RF-H4: ResourceKind string dispatch → enum in resolve.rs

  • Define ResourceKind enum (Filesystem, Network, Clock, AuthContext)
  • Parse at boundary in resolve_std_resources() — unknown kinds fail at
    resolve time with ResolveError, not silently at runtime
  • Exhaustive match in execute(), no fallback arm

RF-H2: TestgenTargetDef Option fields → non-Option with defaults

  • Make test_class, fermi_cost, requires non-Option on TestgenTargetDef
  • Defaults: TestClass::Unit, FermiCost::XS, Vec::new()
  • Remove unwrap_or calls in generate_target_with_types()
  • Apply defaults at DagSpecDef::to_def() boundary
  • Update all 4 construction sites

RF-E4: Fidelity classification smoke tests

  • Add e2e test: makegen callable → Unit/XS (pure DSL rendering)
  • Add e2e test: gist module → Integration/L (REST + Shell transports)
  • Tests compile real DSL modules via build_dsl_graph_with_types()

Scouted: Module-level classify_module() includes transitive auth
callables from std.patterns (github_oidc, local_auth, metadata_oidc),
inflating module classification. Consider callable-scoped classification
or filtering to entry-point-reachable callables.

Mark first three R1 queue items as Done. Add four new scouted
observations to Red Unqueued from implementation and codebase review:

- Transport class metadata triple consolidation (fidelity.rs)
- Passthrough alias heuristic table (resolve.rs)
- looks_effectful_without_kind cleanup after RF-A1 (execute.rs)
- Module-level classify_module transitive inflation (fidelity.rs)

https://claude.ai/code/session_019yLSQYmzRWqSC5WefHgPTn
Scouted 5 additional red team observations during R1 work:
- HTTP method silent fallback (resolve_service.rs:72-79)
- TypeId string dispatch duplication (resolve_service.rs:291-335, 352-366)
- "(unresolved)" magic string for missing inputs (resolve_service.rs:634-641)
- File operation string dispatch (resolve_service.rs:933-948)
- Workflow name string dispatch (unit_commands.rs:300-323)

https://claude.ai/code/session_019yLSQYmzRWqSC5WefHgPTn
Cargo validates all [[bin]] paths in Cargo.toml even when --bin filters
to specific binaries. The "Verify Bootstrap Invariants" CI step removes
target/codegen then checks bootstrap-safe binaries, but Cargo fails
because generated binary paths don't exist.

Fix: after rm, create minimal `fn main() {}` stubs for all generated
binary paths (extracted from Cargo.toml). The bootstrap check still
verifies that gunbc-codegen and gunbc-ci compile independently.

Updated both the generated ci.yml and the cigen template source.

https://claude.ai/code/session_019yLSQYmzRWqSC5WefHgPTn
The cigen code in codegen_cli.rs is ~200 lines of hand-wired string
concatenation for GitHub Actions and GitLab CI YAML. The DSL already
has rendering infrastructure (std/render.dag, std/markdown_render.dag)
and a proven code-generation pattern (tools/makegen.dag).

Tasks follow the makegen pattern:
  CG-1: CI model types in dsl/std/ci.dag
  CG-2: Pure rendering functions in dsl/std/ci_render.dag
  CG-3: Tool entrypoint in dsl/tools/cigen.dag
  CG-4: Delete Rust template code from codegen_cli.rs
  CG-5: Clean up dead code in core/ir/src/transport/ci/

https://claude.ai/code/session_019yLSQYmzRWqSC5WefHgPTn
The lint_allow_pragmas_and_migrations test panicked when
tools/pragma-lint-policy.txt was absent. This file is generated by
the pragma tool, but gunbc-ci runs tools/build.dag (build → test →
clippy) which doesn't include pragma generation.

Add default_pragma_lint_policy() fallback matching the canonical
defaults in gunbc-dag/src/policy/pragma.rs, consistent with the
existing load_disallowed_methods_allowlist() fallback pattern on
line 39 of the same file.

…t worker briefs

Tier-1 brief queue completes (4/5 + 5/5):

4/5 — T-LBP complexity-lens cementing test (§1.8 rows #79 + #87
first entry). Consumer-side cementing test against frozen v2-oracle
snapshot; producer-side Lens<Complexity> instance is upstream
precondition. Per Q-Lens-Behavioral-Parity-R3-Closeability option
(b) RATIFIED at gunbc#828 #issuecomment-4385329180 — T-LBP narrowed
to complexity + cost lenses only.

5/5 — T-LBP cost-lens cementing test + cost_lens_demonstration
(§1.8 rows #80 + #70 + #87 second entry). Absorbs row #70 demo
naturally — same source corpus + lens run; demonstration adds
observable-cost-bound assertions on top of parity check. ≥2
algebra-instances composed + ≥1 recursive call required per row #70.

Both briefs gate on:
- T-LBP per-lens substrate-producer brief landing (Lens<C> instance)
- Frozen v2-oracle snapshot capture (separate brief, pre-v2-retirement)
- DO NOT capture-against-live-oracle (violates
  v2_oracle_no_remaining_test_consumers)
- DO NOT bundle producer/snapshot/algebra-instance authoring per
  Director bundled-scope ratification at gunbc#1739
  #issuecomment-4392225548

Tier-1 5/5 complete. Worker pins assigned at dispatch time once
preconditions land.

* fix(briefs): retire INVARIANTS.md line-number cites in r3-426 brief

Per codex review on PR #1782 (sha c2512cd): the new briefs
introduced fresh `INVARIANTS.md:<line>` citations — the same
stale-line-anchor shape the :425 sweep brief itself names as needing
dissolution. Replaces four line-number references in
r3-426-sfp-subdoc-rename-and-author-worker.md (lines 16, 28, 58, 85)
with prose-anchored locators citing the section anchor + bullet text.

The other PB-lane briefs codex flagged (r3-pb-runtime-equivalence-
corpus-seed-audit.md, r3-pb-t-fixedpoint-worker.md) belong to
neat-bear-351's lane and are not in this PR's scope; will route
separately.

* fix(briefs): correct L6 type count + r3-435 dual-path retirement receipt

Per openai-pro review on PR #1782 (sha c2512cd):

1. L6 brief said acceptance ratchet asserts "five types" exist but
   declares six (ShapeATarget, FormAxis, BehaviorAxis,
   MethodTemplateContractKey, EmissionCell, EmissionPathProjection).
   Updated both occurrences to enumerate all six explicitly.

2. r3-435 brief authorized both Path A (typed-AST reader, deletes
   IntegrationRsScan) and Path B (scanner widening with Char state),
   but retirement receipt language only covered Path B. Updated
   ROADMAP/ledger retirement and authority-audit step 5 to cover
   both authorized dissolution paths.

* fix(briefs): L6 second 'five types' site + T-E-P lookup-gate authority

Per cursor review on PR #1782 (sha 2072b98):

1. L6 brief acceptance bullet at :131 still said "five types" while
   the parenthetical and the Slice step at :117 said six. The prior
   fix only caught one of two sites; corrected the second.

2. T-E-P brief `e_p_call_pattern_lookup_authoritative` acceptance
   named only `lower_call_pattern` as "the only route from call
   site to LoweringTarget" — but Phase 2 explicitly requires
   lenses route through `per_call_pattern_at` (the L-7 single-
   authority lookup), NOT `lower_call_pattern` (compiler-internal).
   Acceptance text rewritten to name `per_call_pattern_at` as the
   consumer-facing gate and clarify `lower_call_pattern`'s
   internal-only scope.

* fix(briefs): strengthen L6 ratchet from count-parity to per-row bijection

Per openai-pro REQUEST_CHANGES on PR #1782 (sha 2072b98): the L6
acceptance ratchet asserted only row-count parity between
emission_path_projections and the union of MethodTemplateContract
rows. Count parity permits duplicate projection keys and missing
source rows — the bridge from list-non-empty proxy to per-row
projection would not be mechanically proven. The whole point of
introducing MethodTemplateContractKey { target, dag_method } is to
provide 1:1 row identity.

Rewrites the ratchet to assert per-row bijection: every
MethodTemplateContract source row has exactly one matching
EmissionPathProjection row by key; every projection key resolves
to exactly one source row; duplicate projection keys fail closed.

(The other openai-pro BLOCKING finding — T-E-P
e_p_call_pattern_lookup_authoritative naming the wrong authority
— was already fixed at 6282a07; the review citation was against
the pre-fix sha 2072b98.)

* fix(briefs): split L6 ratchet into slice-active vs deferred-activation gates

Per BLOCKING inline review on PR #1782 at d924594: the prior
bijection ratchet was unsatisfiable as authored. The
*_method_template_contracts lists at HEAD (rust/python/go) are
non-empty; shipping emission_path_projections: [] alongside a
strict bijection requirement means the bijection cannot pass when
the slice lands — source rows would be uncovered. Prior text
incorrectly said "vacuously true on the empty source set" — the
SOURCE set isn't empty, only the projection set is.

Splits the ratchet into two gate categories:
- Slice-active gates: types/data shape exist + empty-state
  predicate (emission_path_projections == []).
- Deferred-activation gate: per-row key bijection, authored as a
  test scaffold by this slice but #[ignore]'d (or feature-gated
  on len > 0) until Grounding's follow-up populates rows. On
  activation, asserts the bijection over the populated set.

This honors P1 doc faithfulness: the slice's acceptance contract
is satisfiable as authored, and the bijection becomes the
load-bearing gate the row-population PR satisfies.

* fix(briefs): require L6 bootstrap enrollment to honor P2 facts-flow-forward

Per BLOCKING inline review on PR #1782 at L6:34: the slice authored
src/v3/std/cross_target_coverage.dag but never required enrolling
it in the bootstrap/load authority. Without enrollment the file
is dead-letter on disk and EmissionPathProjection can be absent
from the downstream Dag — silent P2 facts-flow-forward violation.

Adds a new Slice step 2 requiring a cross_target_coverage field
on BootstrapFixtures in src/v3/std/extdeps_bootstrap_fixtures.dag
mirroring the *_method_template_contracts enrollment pattern, plus
a loader-visibility ratchet. Renumbers subsequent Slice steps.
Adds matching Acceptance bullet.

* docs(briefs): normalize Practice 4 citation in S3 brief per codex review

Codex review on PR #1782 (sha 2614217) flagged stale citation
"Practice 4 (Step 4 of the type-introduction checklist)" in
S3 brief — no such checklist step exists in the pinned rubric.

Live rule per docs/modeling-discipline.md:131-134 is the "What to
check" checkpoint-comment requirement under Practice 4 (coproduct
dissolution). Updated the S3 reference to cite that line directly
and drop the stale "Step 4 of type-introduction checklist" wording.

S2/S8/S9 already use bare "Practice 4" without the stale steps wording.
S1 (committed earlier today) does not contain the stale phrase.
S6 (pre-existing brief flagged by reviewer as carrying the same
pattern) is out of this branch's scope; flag for separate paydown.

* docs(briefs): sweep stale Practice 4 citations corpus-wide

Codex review on PR #1782 flagged the stale "Step 4 of the
type-introduction checklist" wording — no such checklist exists in
docs/modeling-discipline.md. The live rule is the "What to check"
checkpoint-comment requirement under Practice 4 (coproduct
dissolution) at docs/modeling-discipline.md:131.

Sweep across docs/ found 2 additional briefs carrying the stale
phrasing (S3 fixed previously at 9db003d):

- docs/briefs/r3-l6-emission-path-projection-substrate-worker.md
- docs/briefs/r3-x1b-s1-transform-dispatch-substrate-worker.md

Both updated to cite the live rule directly. Verified zero
remaining "type-introduction checklist" or "Step 4 of the"
references in docs/ tree.

* docs(briefs): add Practice 4 citation discipline note to authoring checklist

Per parent inbox status flag at gunbc#828 #issuecomment-4385346221:
add a Citation discipline section to brief-authoring-checklist.md
naming the correct shape — Practice 4 (coproduct dissolution) +
"What to check" rule at docs/modeling-discipline.md:131 — and
calling out the stale "Step 4 of the type-introduction checklist"
phrasing as a failure mode. References the corpus sweep at
2dc92f3.

Prevents future briefs that copy old templates from re-introducing
the stale citation pattern.

* docs(r3): cascade work post-Director ratification — S1 worker, R4 routing, Unit/Quantity canvas

Per Director ratification at gunbc#828 inbox response 2026-05-06
(zesty-bear-812):

1. S1 Q1+Q2 RATIFIED → author S1 gap-test representative worker brief
   (`r3-substrate-s1-gap-test-representative-worker.md`). Dispatchable
   on T-E-P Phase 1 + E6-G0d landing; closes ledger row #61.

2. S2 Q2 RATIFIED (option-(b) T-LBP narrowing) + S3 + S8 deferrals →
   R4 carve-out routing ledger (`docs/r4-carve-out-routing.md`).
   Captures C1 (parallelism lens), C2 (effect_enum lens), C3
   (register narrowing), C4 (deferred MachineConstraint axes),
   C5 (rounding-mode product extension), C6 (Unit/Quantity).
   Cascade messages to Verification / Grounding / Debt-Paydown Mgrs.

3. S9 Phase-3 dimensional refinement boundary → Unit/Quantity carrier
   canvas (`r3-substrate-s9-unit-quantity-carrier-canvas.md`).
   Surfaces Q-Unit-1..5 for Director ratification: carrier name,
   2-axis vs 3-axis Phase-1, Duration/Seconds collapse, Refined
   composition order, Practice 4 classification.

Updates §1.8 ledger receipts for carved items; R3 closure receipts
treat carved items as explicitly-deferred (not drift).

* docs(briefs): citation-discipline fix-forward — anchors/quotes, not line numbers

Director redirect at gunbc#828 #issuecomment-... noted the citation
paydown's replacement form (`docs/modeling-discipline.md:131`) is the
same drift class as the original fabricated-step error. Bare line
numbers shift silently on any doc edit above the cited line.

Generalized fix:
- brief-authoring-checklist.md "Citation discipline" section
  rewritten to prohibit bare line-numbers across ALL cross-doc
  references (modeling-discipline.md, r3-program-plan.md,
  r3-structure.md, INVARIANTS.md, MODELING.md, etc.). Use section
  anchors (#section-name) or rule-text quotes.
- 3 briefs that swapped in :131 (S3, S6, X1B) re-converted:
  - docs/modeling-discipline.md#4-coproduct-dissolution anchor
  - "What to check" rule quoted inline (self-contained)

Brief-authoring-checklist failure-mode section names both vectors
(fabricated step + bare line numbers) and references both sweep
commits in audit trail.

Broader cross-doc citation sweep across briefs I authored on this
branch (frontmatter authority-docs lists, body prose) is recommended
per Director note — flagging as separate paydown task; this commit
closes the immediate recurrence vector.

* docs(briefs): fix unfaithful Int=AbelianGroup<Nat> + sweep stale 'Step 4' refs

Per openai-pro review on PR #1782 sha 0ecd481 (gunbc#1782 #...):

BLOCKING fix (P1 modeling faithfulness):
- S9 + S3 directed workers to model `Int = AbelianGroup<Nat>`,
  but Nat is not an Abelian-group carrier (additive inverses
  not representable). Reframed:
  - `Int` is the additive Abelian group on integers (carrier Z);
    `Nat` is a commutative monoid under addition.
  - Algebraic relationship is **explicit group-completion**:
    `Int ≡ GroupCompletion<CommutativeMonoid<Nat>>` — NOT
    `AbelianGroup<Nat>` parameterization.
  - Worker either models `Int` directly as `AbelianGroup`
    (terminal Abelian-group instance) OR introduces explicit
    `GroupCompletion<M>` substrate carrier; decision lands in
    Phase-1 PR per P1 procedure.
- S3 cross-reference + Phase-4 algebra-axis preservation note
  reframed accordingly.

NON-BLOCKING in-PR cleanup (Practice 4 citation discipline):
- 6 briefs still carrying stale 'Practice 4 Step 4' wording
  (r3-coproduct-1/2/3, r3-l6, r3-t-e-p, r3-x1b) updated to use
  the section anchor (`docs/modeling-discipline.md#4-coproduct-dissolution`)
  + inline rule-text quote ("What to check") form per the
  citation discipline established in `b4cae5299`.

Closes both findings from openai-pro review.

* docs(briefs): Q-Unit-1..5 RATIFIED — apply Scale.Unit→One rename + ratification banner

Director ratified Q-Unit-1..5 at gunbc#828 #issuecomment-... 2026-05-06
(zesty-bear-812). All 5 questions ratified; one rename required:

- Scale enum's `Unit` value collides with outer `Unit<Q, S>` carrier
  name (`Unit<Time, Unit>` is shadowing-confusing). Rename to `One`.
- Duration ≡ Unit<Time, One> (collapses with Seconds per Q-Unit-3).
- Milliseconds ≡ Unit<Time, Milli>.

Canvas updated:
- Top-level RATIFICATION banner records all 5 ratifications + rename
- Scale enum: `Unit` → `One` (with inline rename receipt)
- Sketch product expansions use `Unit<Time, One>` / `Unit<Time, Milli>`
- Phase-3 reframe table products updated
- Q-Unit-3 prose collapse reference updated

Subsequent worker brief authoring (Unit/Quantity carrier landing
post-prerequisite) inherits the renamed shape.

* docs(briefs): Unit/Quantity carrier worker brief — Q-Unit-1..5 RATIFIED

Worker brief consumes the ratified Unit/Quantity canvas
(`5f22fd06e` ratification banner). Phase-1 lands `Unit<Q, S>` +
`Quantity` + `Scale` declarations at the ratified shape (Scale's
`One` value per Q-Unit-1 rename). Phase-2 reframes S9 Phase-3
dimensional refinements (Duration / Seconds / Milliseconds) to
outer-Refined / inner-Unit composition per Q-Unit-4 RATIFIED.
EpochMs deferred to R4 C6 (Aspect-axis follow-up).

Practice 4 marks pre-determined per Q-Unit-5: `Unit<Q, S>` 🟢
PRIMITIVE; `Quantity` + `Scale` 🟡 SCAFFOLD with "consumed by ≥1
emission rule" dissolution trigger.

Cross-program handoff to Grounding Mgr (#1745) for dimensional
emission consumption documented.

Worker pin TBD — dispatchable when idle pool refreshes.

* docs(briefs): S9 Phase-1 reframed — Int landed at #1466; UInt-only migration

Per proud-lynx-311 dispatch ack at gunbc#1739 #issuecomment-...
2026-05-06: re-grep at HEAD revealed substrate state diverges
materially from S9 brief's "Option A vs B decide" framing.

Reality check at HEAD:
- `dsl/std/integer.dag:55` already carries
  `type Int = AbelianGroup<GroupCompletion<Nat>>` per Slice 3 PR
  #1466 / commit `4ba0a6d04`. Single-authority Q6 audit doc at
  `docs/audit/t-numeric-construction-group-completion-6q.md`
  ratified this shape and explicitly rejected the compact form.
- `dsl/std/integer.dag:56` still on legacy `type UInt = UInt64`
  alias; UInt migration is the actual Phase-1 worker scope.

Brief Phase-1 step 1 reframed: Int landing acknowledged; worker
confirms HEAD match. Phase-1 step 2 reframed: UInt migration
target named (`type UInt = CommutativeMonoid<Nat>`); fixed-width
rows preserved per existing legacy-rows policy.

Historical Option A vs B framing kept as note (superseded).

Confirmed S9 dispatch ack from worker; UInt-only Phase-1 PR is
in-scope. Emission entries deferred per S3 (valiant-ant-72
pre-landing); Phase-2 deferred per S8 (quiet-boar-160 pre-landing).

* docs(briefs): fix two BLOCKING citation drift items per codex review

Codex review on PR #1782 sha 5f22fd0 flagged two authority-receipt
gaps:

1. brief-authoring-checklist.md:118 — `<this-commit>` placeholder in
   the failure-mode section was unverifiable post-merge. Replaced
   with `b4cae5299` (the actual anchor/quote conversion commit).

2. r3-378-http-path-helper-fail-open-worker.md:84 — `INVARIANTS.md
   C-8 fail-closed` cited without anchor or rule-text quote, in
   violation of the citation discipline added in this PR.
   Converted to `INVARIANTS.md#p3-fail-closed` (P3 heading anchor)
   + inline rule-text quote naming P3 + C-8.

PR's own discipline now consistently applied across the diff.

* docs(briefs): sweep bare .md:NNN citations in Substrate-Mgr-authored briefs

Per Director recommendation in citation-discipline thread (gunbc#828
follow-on): bare line-number references drift silently. Swept 19
remaining instances across 5 briefs I authored on this branch:

- docs/briefs/r3-substrate-s1-q-class-2-chain-break-gap-test-canvas.md
- docs/briefs/r3-substrate-s1-gap-test-representative-worker.md
- docs/briefs/r3-substrate-s2-t-lbp-scope-calibration-canvas.md
- docs/briefs/r3-substrate-s3-machine-constraint-carrier-worker.md

Conversion: bare `file.md:NNN` → `file.md §"Section name"` form.
Stable; survives doc edits; human-readable. Section names per
HEAD heading audit.

Verification: `grep -nE '.md:[0-9]+' docs/briefs/r3-substrate-*.md
docs/r4-carve-out-routing.md` returns zero results in
Substrate-Mgr-authored scope.

Broader corpus scope (~232 references across non-Substrate briefs)
remains as separate paydown task.

* docs(briefs): fix BLOCKING + NON-BLOCKING items per openai-pro review on a462f00

Three findings addressed; 2 BLOCKING + 1 NON-BLOCKING:

BLOCKING — R3/R4 dual authority for Unit/Quantity carrier:
R4 carve-out C6 narrowed from "Unit/Quantity carrier landing"
(deferred all of it) to **"Aspect-axis (PointKind) follow-on
for EpochMs and instant/rate-shaped refinements only"**. The
2-axis Measure<Q,S> carrier landing IS in R3 per Q-Unit-1..5
RATIFIED; only the Aspect axis (PointKind = Magnitude | Instant
| Rate) carves to R4. Cascade-message C6 reference + R4 program-
plan input list updated to match. Cross-Mgr message clarifies
Grounding consumes 2-axis dimensional refinements in R3.

BLOCKING — Locked design partially applied (Scale.Unit→One
rename in canvas alternate-sketch sections):
- Canvas line 105-108 alternate sketch ("Open question: Instant
  vs Duration axis") still used pre-rename `Unit` Scale value;
  added pre-ratification disclaimer marking the section as
  deferred to R4 C6 + noting `Unit` is pre-rename
- Canvas line 163 Q-Unit-3 collapse note: `Scale = Unit` → `Scale = One`

(BLOCKING — bare line-numbers in S1 canvas frontmatter): NOT
APPLICABLE — already fixed at sweep commit 127287a prior to
review; reviewer was on sha a462f00 pre-sweep.

NON-BLOCKING — placeholder receipts:
- brief-authoring-checklist.md `#issuecomment-...` → concrete ID
  4385393971 (Director's anchor-discipline reply)
- r3-substrate-unit-quantity-carrier-worker.md (3 occurrences)
  + canvas RATIFICATION banner: `#issuecomment-...` → concrete ID
  4385412256 (Q-Unit ratification reply)
- `<this-commit>` placeholder in checklist already fixed at 5be1c99

Verification: zero `#issuecomment-...` or `<this-commit>` placeholders
in docs/briefs/ + docs/r4-carve-out-routing.md.

* docs(briefs): codex BLOCKING review fixes — Practice 4 source-level + policy scope

Three BLOCKING findings on PR #1782 (codex sha b913e2f):

1. **Citation-discipline policy scope**: addressed by scoping
   the rule prospectively to briefs landing after the policy
   commit (`b4cae5299`). Pre-existing corpus references are
   flagged as paydown but NOT individually blocking; coordinated
   single-PR sweep is the right paydown shape. Substrate-Mgr scope
   already swept at `127287a66`.

2. **R4 C6 reconciliation**: already fixed at `6e5a5481a` (R4 C6
   narrowed to Aspect-axis follow-on for EpochMs only; 2-axis
   carrier landing IS in R3). Codex sha b913e2f was pre-fix.

3. **Practice 4 source-level vs PR-body conflation**: corrected.
   Acceptance bullet for Unit/Quantity worker brief now requires
   inline checkpoint comments on the LIVE declarations in
   `dsl/std/units.dag` (load-bearing artifact per
   `docs/modeling-discipline.md#4-coproduct-dissolution` "What to
   check"). PR-body summary is supplementary, not substitute.

Closes the review's reconciliation gates.

* docs(briefs): absorb Q-MachineConstraint + Q-Unit-1-Recanvas ratifications

Two major Director ratifications absorbed:

1. Q-MachineConstraint-Carrier RATIFIED at gunbc#828
   #issuecomment-4385530115 (Brian directive 2026-05-06: "universal
   substrate, ratify defaults"; PR #1817 queued). 6 sub-decisions:
   - MachineWidth<bits> only for R3; defer RegisterClass / EndianMode
     / Alignment / signedness post-R3
   - Parametric Compose<Algebra, MachineConstraint> type-level
     interaction shape (lookup-maps REJECTED — AlgebraMachineProduct
     record-keyed table form retracted)
   - Int<64> ≡ Compose<AbelianGroup, MachineWidth<64>> (algebra-side
     options A and B preserve interaction semantics)
   - Real<64> ≡ Compose<ApproximateField<Rational>, MachineWidth<64>>
     (algebra approx + machine approx as independent composing axes)
   - ≥3 pairs is minimum, not target
   - UNIVERSAL substrate: every target carries machine-constraint
     facts; targets without native machine-width semantics handle
     omission at Grounding-level discharge (target-conditioned
     lowering NOT target-conditioned substrate)

   Reframed: S3 brief Phase-1, S3 Phase-3/4 emission entries,
   S8 Phase-1/2/3 (ApproximateField<Real> → ApproximateField<Rational>;
   AlgebraMachineProduct → Compose<...>), S9 emission entries.

2. Q-Unit-1-Recanvas RATIFIED Measure<Q, S> at gunbc#828
   #issuecomment-4385539791. valiant-ibex-312's substrate-state
   grep caught Unit<Q, S> collision with kernel Unit at
   dsl/std/types.dag:176; Director ratified Measure<Q, S> as
   outer carrier name (conventional in scientific computing;
   no dsl/std/ collision).

   Reframed: Unit/Quantity worker brief throughout (Unit<Q,S> →
   Measure<Q,S>; dsl/std/units.dag → dsl/std/measure.dag); canvas
   spec sections + sketch products (Refined<Measure<Time, ...>...>);
   R4 carve-out C6 with informal/formal name disambiguation note.

Both rename + reshape are now consistent across S3 / S8 / S9 /
Unit-Q briefs + canvas + R4 routing. Workers (valiant-ant-72 on S3,
quiet-boar-160 on S8, proud-lynx-311 on S9, valiant-ibex-312 on
Unit-Q) all dispatch against the ratified shape.

* docs(briefs): S11 Slice C worker brief — ROADMAP :425 retirement post-#1801

Cascade-clearance trigger fired post-#1801 (Slice B) merge
2026-05-06. S11 brief authored per B1 RATIFIED prose+regen
bundling discipline.

Phase 1: per-file edits across the post-A+B residual list (~10
files per smart-ram-167's Slice B post-rebase enumeration);
anchor + rule-text-quote pattern per current citation discipline;
bootstrap regen in same PR (no split).

Phase 2: ROADMAP :425 row PARTIAL → Retired with 3-slice receipt;
Q-Slice-C-Retirement-Receipt resolution.

Worker pin smart-ram-167 (#1759) — Slice B precedent owner.
Dispatch packet sent separately to #1759.

* docs(briefs): Q-Refined-Phantom-Composition (c) RATIFIED — defer literal Refined form

Director ratified option (c) at gunbc#828 #issuecomment-... 2026-05-06:
drop `non_negative` predicate at Measure (phantom) layer; rely on
`Quantity = Time` tagging for non-negative-magnitude semantics.

Q-Unit-4 outer-Refined / inner-Measure composition is preserved as
**conceptual model**; the literal `Refined<Measure<...>, predicate>`
form is **deferred to value-typed-integration follow-up** when
substrate gains Refined<> as first-class type expression and
dimensional refinements get value-typed integration.

Updates:
- Canvas RATIFICATION banner Q-Unit-4 row reframed to "conceptual
  model; literal form deferred"
- Canvas Phase-3 reframe table: Duration / Milliseconds drop the
  Refined<...> wrapper; rely on Quantity tag
- Worker brief Phase-2 prose + reframe table + Acceptance bullet
  all reflect deferred-literal-form posture

valiant-ibex-312 unblocked to proceed with Phase-2 (Grounding
handoff doc) per the (c)-shaped Acceptance.

* docs(briefs): S12 F2 + F8 doc-sharpening worker brief — post-#1820 cascade

#1820 (Slice C) merged 2026-05-06; ROADMAP :425 row Retired closes
the prose-reference paydown program. S12 cascade-clearance trigger
fires per B6 RATIFIED single bundled Mgr-tier doc-sharpening PR.

Scope: F2 (.v3 filename-suffix grammar dispatch) + F8 (bootstrap
load-order/exclusion authority) — single bundled PR per B6.
Cross-program coordination with PB Mgr (#1742) per design schedule
§3 P5 (comment-only OR co-author; no duplicate PR).

Worker pin smart-ram-167 (#1759) — Slice C precedent owner;
pattern-familiar with prose+regen bundling discipline. Dispatch
packet sent separately to #1759.

* docs(briefs): S9 brief — UInt landed via #1818; algebra label corrected to CommutativeSemiring

Per proud-lynx-311 merge report at gunbc#1746 #issuecomment-...
2026-05-06: PR #1818 landed `type UInt = Nat` after codex BLOCKING
review on initial `CommutativeMonoid<Nat>` form (P2 facts-flow-forward
violation — wrap projects out Nat's multiplicative monoid + identity 1).

Final landed form preserves full `CommutativeSemiring<Magnitude>`
surface — Nat IS a commutative semiring (addition + multiplication
+ 0 + 1). Algebra-side label for UInt is CommutativeSemiring, NOT
CommutativeMonoid (corrects my earlier dispatch labeling).

S9 Phase-1 step 2 marked LANDED with merge ref. Phase-1 step 3
emission entries reframed:
- Int<N> ≡ Compose<AbelianGroup, MachineWidth<N>>
- UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>>

Worker discipline + reviewer caught a substrate-state error in my
brief framing; brief now matches landed reality.

* docs(briefs): fix contradictory (c) guidance in Unit/Quantity worker brief

Codex BLOCKING review on PR #1825 sha 1bce041 caught a real
contradiction: brief Phase-2 prose at lines 115-118 stated
"predicates do NOT attach at the Measure (phantom) layer" per
Q-Refined-Phantom-Composition (c) RATIFIED, but immediately
following paragraph at lines 130-132 still said "Refined predicate
non_negative applies at the Measure-typed level" — left over from
the original Q-Unit-4 framing.

Updated lines 130-137 to consistently apply (c) shape: predicates
deferred to value-typed-integration follow-up; dimensional semantics
ride on Quantity tag at Measure layer; worker authors 3 in-scope
refinements WITHOUT predicate at this layer.

P2 boundary discipline restored: brief now gives single-authority
guidance for Phase-2 substrate landing.

* docs(briefs): name predicate authority + concretize ratification ID — codex BLOCKING

Codex BLOCKING review on PR #1825 sha 32541a5:

1. (BLOCKING) Q-Refined-Phantom-Composition (c) ratification deferred
   phantom-carrier predicates without naming the value-level predicate
   authority. Updated canvas Q-Unit-4 RATIFICATION row to explicitly
   name: 'predicates re-attach at value-typed Int/UInt level via
   where-sugar (e.g., range(min: 0) per current dsl/std/types.dag
   precedent)' when value-typed integration lands.

2. (BLOCKING) Worker brief option-c reframe didn't sweep the audit
   receipt §5 (Carrier dissolves the bridge). Updated to consistently
   apply (c) shape — dimensional semantics ride on Quantity tag at
   Measure layer; value-level predicate authority deferred; until
   then, range/gt_zero constraints attach at value-typed Int/UInt
   via where-sugar per dsl/std/types.dag convention.

3. (NON-BLOCKING) Canvas had #issuecomment-... placeholder for the
   (c) ratification message ID. Replaced with concrete
   #issuecomment-4385687075 per dashboard relay header.

Brief now names a single value-level authority (Int/UInt where-sugar)
for value-range facts; phantom-layer Quantity tag carries only
dimensional semantics. P2 boundary discipline maintained.

* docs(briefs): S12 RETIRED per Director option (2) ratification

Director ratified option (2) at gunbc#828 #issuecomment-4385873...
2026-05-06 post smart-ram-167's substrate-state STOP-AND-ESCALATE:

- F2 absorbed by 2026-05-04 routing + #1662 closure
  (`Result/DivError span.file-keyed` retired)
- F8 topical concerns distributed across live rows
  (Class 5 Gap 3 `bootstrap.rs::std_fixtures()`; Character-level
  load-set / bootstrap; Filename-sentinel-bridges) with own owners
- Doc-discipline goals absorbed by per-Mgr citation paydown
  routing at gunbc#828 #issuecomment-4385583247

Frontmatter updated to RETIRED with absorption receipt. Worker
(smart-ram-167) pin freed.

Director-side acknowledgment of Substrate Mgr's option (2) recommendation:
"Substrate Mgr's option (2) recommendation is the right move
structurally. Most Mgrs default to 'synthesize work to fill the brief'
when canvas-vs-HEAD mismatch surfaces. Recommending retirement when
the work is genuinely absorbed is harder discipline."

* docs(briefs): S7 PR-F (BoundDeclaration consumer + ReferenceModel<T>) worker brief

Per cascade-clearance trigger fired post-#1782 merge 2026-05-06.
loyal-wolf-828 (#1764) acknowledged S7 dispatch with substrate-state
pre-flight grep (gunbc#1764 #issuecomment-4385872...) and surfaced
await-brief posture. This brief satisfies that prerequisite.

Worker pre-flight inventory absorbed:
- BoundDeclaration substrate landed (substrate.dag StaticBound +
  PlatformDependent); partial BoundDeclarationView consumer in
  fold.rs (ScratchIntExamples scope; doc-explicit partial)
- ReferenceModel<T> NOT yet in dsl/std/ (substrate-fact-introduction
  required; design-emission-model.md §Q2 framing)

Phase-1: BoundDeclaration consumer broadening to full
design-emission-model.md surface (u128 / isize / usize / walker
arms / pilot mirror).

Phase-2: ReferenceModel<T> P1 substrate-fact-introduction with
DFS-of-concept-DAG + Practice 4 in-source checkpoint comment +
named consumer demand (Grounding G1).

Phase-3: cross-program handoff to Grounding Mgr (#1745) for
G1 (T-Ground-Rust Phase 1).

Closure predicate: unblocks Grounding T-Ground-Rust Phase 1.
Worker pin loyal-wolf-828 holds; dispatch fires immediately
on this brief landing.

* docs(briefs): S9 Slice 2.5 — predicate-registry + PB-1 shim retirement (Path 3 RATIFIED)

Director ratified Path 3 at gunbc#828 #issuecomment-4390333451
post proud-lynx-311's pre-flight DFS at gunbc#1746 #issuecomment-4390253616.

Brief reframes Slice 2.5 from S-sized (primitive + 1 consumer) to
L-sized (predicate registry + PB-1 shim retirement). 5 deliverables:
1. gt_zero primitive predicate
2. Predicate registry infrastructure (resolver-side substrate-fact-introduction)
3. PB-1 shim retirement (span.file=='dsl/std/types.dag' special case dissolves)
4. Migration of existing types.dag predicates (range, pattern, etc.)
5. PositiveInt = Refined<Nat, gt_zero> consumer update

Per Director hard scope bars: no parallel predicate-resolution path;
no per-call-site special-casing; PB-1 shim retirement non-negotiable
in same slice. Single PR per Path 3 RATIFIED.

Discipline anchors: feedback_construction_over_ratchets (PB-1 shim
is bridge); feedback_dissolve_bridges (registry is structural fix);
feedback_no_textual_enforcement_bridges (file-path special-case is
anti-pattern shape); P1 substrate-fact-introduction procedure.

Worker pin proud-lynx-311 — Director pre-cleared on pre-flight DFS
context. PR #1840 (partial Slice 2 — NonNegativeInt = Nat) MERGED
at 16:54Z; Slice 2.5 dispatchable immediately on this brief landing.

* docs(briefs): Slice 2.5 audit receipt — Mgr independent grep parallel-verifies worker DFS

Codex BLOCKING review on PR #1845 sha 2d23094 flagged: external PR
receipt absorbed as live substrate state without re-grepping local
std declarations at brief authoring time. Authority receipt §1
cited proud-lynx-311's pre-flight DFS as authority but didn't
record Mgr-side independent verification.

Updated audit receipt §1 + §4 to record Mgr's independent grep at
HEAD as parallel verification:
- gt_zero zero matches in dsl/std/ + src/v3/ (verified)
- NonNegativeInt = Nat at dsl/std/integer.dag:133 (#1840 land)
- PositiveInt = Int where range(min: 1) at dsl/std/types.dag:255
- PB-1 shim doc-block confirms bridge-text framing
- Predicate registry confirmed not present

Worker DFS remains the dispatch-time discipline (substrate-state
grep at dispatch); Mgr's independent grep is parallel verification,
not substitute. Per Director's pattern note at gunbc#828
#issuecomment-4390199218 + #issuecomment-4390333451: dispatch-packet
authoring discipline includes Mgr-side substrate-state-grep, not
just relay of worker findings.

* docs(briefs): Slice 2.5 brief — Int extensibility scope-bound; lower.rs cites anchored

openai-pro REQUEST_CHANGES on PR #1845 sha 2d23094 flagged 2 issues:

BLOCKING — P1 modeling faithfulness / substrate scope leak:
`gt_zero` Int-side extensibility was left to 'worker judgment if
generalization cheap'. Per feedback_construction_over_ratchets:
don't speculatively extend predicate-carrier compatibility ahead
of named consumer demand. Reframed to **EXPLICITLY OUT-OF-SCOPE**
for Slice 2.5; Nat-only registration. Future Int-side consumer
surfaces as separate substrate-fact-introduction (P1 procedure)
brief with own consumer-demand receipt.

NON-BLOCKING — citation discipline self-violation:
3 instances of bare `lower.rs:821-835` line-range citations
contradict the brief's own 'no bare :NNN' requirement at line 211.
Converted to function-name anchored form:
`src/v3/compiler/src/lower.rs` (`lower_type_alias_refinements_phase` doc-block).

Both findings absorbed; no parallel scope ambiguity remains;
brief now self-consistent on citation discipline.

* WIP: R3 Substrate

* docs(briefs): Slice 2.5 brief — audit-receipt cites converted to declaration-name anchors

cursor APPROVE_WITH_COMMENTS on PR #1845 sha ebf6ac1 noted citation
self-inconsistency: audit-receipt section §1 + §4 used bare
`dsl/std/integer.dag:133` and `dsl/std/types.dag:255` line-number
pins despite the brief's own no-bare-:NNN rule.

Converted to declaration-name-anchored form:
- 'declaration named NonNegativeInt' (with reproducible grep command)
- 'declaration named PositiveInt' (with reproducible grep command)
- 'lower_type_alias_refinements_phase doc-block' for PB-1 location

Brief now fully self-consistent on its own citation discipline.
Verified zero remaining .dag:NNN / .rs:NNN / .md:NNN bare cites.

* docs(briefs): Slice 2.5 brief — Path (a) RATIFIED carrier+argument contract verification

Director Path (a) RATIFIED at gunbc#828 #issuecomment-4390760353
(triage) + #issuecomment-4390794121 (convergence ack):
predicate-body lowering with carrier+argument contract
verification at lower-time IN SAME SLICE. Placeholder semantics
REMOVED from registry path.

Codex REQUEST_CHANGES surfaced that registered-predicate-without-
contract = silent acceptance per feedback_fail_closed_discipline.
Brief reframe absorbs Path (a):

Hard scope bar #5 added:
- Same-slice carrier+argument-contract verification
- Mismatched carrier OR malformed argument → Diagnostic::ResolveError
- No 'named but not checked' path remains

Scope expansion section added (L → XL):
- Predicate-body lowering for all 7 registered predicates
- Per-predicate arg-shape validation
- Multi-session work acknowledged
- Carrier-check at 788d6ac retained; predicate-body builds on top

Acceptance bullets updated: gt_zero with arg-shape validation +
all 7 predicates with carrier+argument contract verification.

Director-pinned brief-authoring discipline: dissolution trigger
named in a brief authored as substrate-fact-introduction must
specify same-slice acceptance, not deferred follow-up. Otherwise
the brief encodes 'land bridge + defer dissolution' anti-pattern,
the same shape feedback_construction_over_ratchets warns against
at implementation layer applied at brief authoring layer.

This is the 11th miss this session — but the pattern surfacing it
(direct sweep + Codex REQUEST_CHANGES + Director ratification)
produces structural fixes that prevent the next miss class. Brief
revision is the structural recovery.

* docs(briefs): Slice 2.5 brief — Path 2 RATIFIED (Gap 1 discharge + Q-Regex carve-out)

Director Path 2 RATIFIED at gunbc#828 #issuecomment-4391985613
post Rung 3 STOP at gunbc#1746 #issuecomment-4391946213.

Path 2 narrowing of Path (a):
- gt_zero + range body synthesis already landed (5f3c40c)
- Gap 1 discharge mechanism: extends scalar-literal predicate
  evaluation at lower-time. L-class; lands SAME SLICE per
  same-slice-dissolution discipline
- non_empty + brand body synthesis: lands via Gap 1 discharge
- pattern / format / content: fail-closed-with-named-dep at
  user-code authoring layer (Diagnostic::ResolveError naming
  Q-Regex-Primitive). NOT placeholder; structural rejection
- PB-1 shim FULLY RETIRED per hard scope bar #3
- Q-Regex-Primitive carved as follow-on substrate-fact-introduction
  (XL substrate; not pre-authored per feedback_construction_over_ratchets)

Acceptance updated:
- 4 of 7 body-synthesized in same slice
- 3 of 7 fail-closed-with-named-dep (no placeholder semantics)
- Gap 1 discharge mechanism landed (no partial implementation)

Worker disposition: proud-lynx-311 continues Rung 3 with Gap 1
implementation + non_empty/brand body synthesis + pattern/format/
content fail-closed-with-named-dep diagnostic.

* docs(briefs): S9 Phase-1 Step 3 emission entries — Tier-1 brief authoring (1/5)

First Tier-1 brief landing post Director auto-nudge on assignment
#1858. Authored against Q-MachineConstraint sub-decisions ratified
shape now landed at #1856:

- Int<N> ≡ Compose<AbelianGroup, MachineWidth<N>> → Rust i32/i64/i128
- UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>> → Rust u32/u64/u128
- 6 concrete instantiations (≥3 minimum per sub-decision 5)
- Cross-program handoff to Grounding Mgr (#1745) for G2 emission consumption
- numeric_construction_demonstration Acceptance bullet (Int<32> round-trip);
  Real<64> half deferred to S9 Phase 2 / S8 Float cascade

Brief authored with substrate-state-grep discipline + same-slice-
dissolution discipline (no deferred trigger; demonstration in same
slice or explicitly carved). 5-question authority audit completed
in brief body.

Worker pin proud-lynx-311 (S9 holds); brief queues post-Slice-2.5
completion as natural follow-on.

Tier-1 brief queue progress:
- 1/5 authored (this brief)
- 4 remaining: S9 Phase-2 Float coordination; T-LBP complexity
  cementing; T-LBP cost cementing; S3 Phase-2 parser-grammar

* docs(briefs): S3 Phase-2 parser-grammar surface — Tier-1 brief 2/5

Authored per Director freed-pool pressure at gunbc#828
#issuecomment-4392095857 + Tier-1 brief-queue commitment.

Brief covers parser-grammar surface for Compose<Algebra, MachineConstraint>
interaction syntax post-#1856 (Phase-1 carrier slice landed):

- Phase 2.1: Parser surface per ratified Q-MachineConstraint-Grammar-Shape
- Phase 2.2: Bootstrap demonstrator with >=3 algebra*machine-axis pairs
- Phase 2.3: Class 1 5-criteria Pass receipt (criteria 1-4; criterion 5
  v2-oracle parity may carve)
- Phase 2.4: numeric_construction_demonstration co-receipt with S9 Phase-1
  Step 3 emission entries brief

Director ratification HOLDS on grammar bikeshed:
- Candidate A: Int @ Width<32> (annotation form)
- Candidate B: Int with MachineWidth<32> (with-form)
- Candidate C: Int<32> (positional generic — fits existing convention)
- Candidate D: Compose<AbelianGroup, MachineWidth<32>> (no parser change;
  type aliases provide convenience names)

Worker pin valiant-ant-72 holds (S3 Phase-1 precedent owner); freed-pool
until Director ratifies grammar shape.

Tier-1 brief queue progress: 2/5 authored (this brief + S9 Phase-1 Step 3).
Remaining: S9 Phase-2 Float coordination; T-LBP complexity cementing;
T-LBP cost cementing.

* docs(briefs): S3 Phase-2 brief — fix internal contradiction on Class 1 closure scope

Codex BLOCKING review on PR #1889 sha ec609b4 flagged real
contradiction:

- Provenance section claimed '5-criteria Pass closed' (line 229)
- Phase 2.3 said 'criterion 5 may queue separately' (line 154)
- STOP-AND-ESCALATE bullet 1 ratified 4-of-5 carve-out (line 181)

Updated Provenance to consistently state criteria 1-4 close in this
slice; criterion 5 (v2-oracle parity) cementing test may carve to
separate slice. Single 4-of-5 framing throughout. INVARIANTS.md
'Documentation Describes Live State' satisfied.

Per feedback_construction_over_ratchets: don't claim closure that
isn't structurally complete. 4-of-5 + named carve is the honest
shape; 5/5 only on cementing-test land.

Address openai-pro BLOCKING + NON-BLOCKING findings on PR #1889:

BLOCKING (boundary discipline / same-PR consumer): S9 Phase-1 Step 3
+ Phase-2 Float briefs claimed DECLARED → CONSUMER_LANDED upon merge
while only requiring cross-program handoff receipt to Grounding G2.
For target-primitive substrate entries, handoff is not landed-consumer
proof. Reframed both briefs to advance rows DECLARED → PRODUCER_LANDED;

Director ratified Option A revised at gunbc#1739 #issuecomment-4392329709
(2026-05-06). Final brief shape:
- 4 predicates body-synthesize via Gap 1 (gt_zero / range / non_empty
  / brand)
- pattern / format / content STRUCTURALLY ABSENT from registry (not
  pending-with-placeholder); user-code where-clause produces
  Diagnostic::ResolveError naming Q-Regex-Primitive as separate
  substrate-fact-introduction follow-on
- ~12 types.dag refined-type declarations migrate to drop
  pattern/format/content where-clauses with inline-comment receipts
  pointing to Q-Regex restoration path; 1 extdep (sts_endpoint)
  adapts as needed
- PB-1 shim FULLY RETIRED — no exception, no preserved branch
- Q-Regex-Primitive as separate brief / worker pin / Director
  ratification cycle when concretely needed (Option B XXL bundling
  REJECTED)

Phase ordering rewritten to absorb migration as explicit phase
between predicate enrollment and shim retirement. proud-lynx-311

Tier-1 brief queue completes (4/5 + 5/5):

4/5 — T-LBP complexity-lens cementing test (§1.8 rows #79 + #87
first entry). Consumer-side cementing test against frozen v2-oracle
snapshot; producer-side Lens<Complexity> instance is upstream
precondition. Per Q-Lens-Behavioral-Parity-R3-Closeability option
(b) RATIFIED at gunbc#828 #issuecomment-4385329180 — T-LBP narrowed
to complexity + cost lenses only.

5/5 — T-LBP cost-lens cementing test + cost_lens_demonstration
(§1.8 rows #80 + #70 + #87 second entry). Absorbs row #70 demo
naturally — same source corpus + lens run; demonstration adds
observable-cost-bound assertions on top of parity check. ≥2
algebra-instances composed + ≥1 recursive call required per row #70.

Both briefs gate on:
- T-LBP per-lens substrate-producer brief landing (Lens<C> instance)
- Frozen v2-oracle snapshot capture (separate brief, pre-v2-retirement)
- DO NOT capture-against-live-oracle (violates
  v2_oracle_no_remaining_test_consumers)
- DO NOT bundle producer/snapshot/algebra-instance authoring per
  Director bundled-scope ratification at gunbc#1739
  #issuecomment-4392225548

Tier-1 5/5 complete. Worker pins assigned at dispatch time once
preconditions land.

* canvas: emission-provenance substrate shape disposition (supersedes PR #1902 PROPOSAL)

Substrate Mgr canvas authored post-codex BLOCKING + PM disposition
handoff at gunbc#846 #issuecomment-4392510255.

Two real substrate-shape questions stacked:

Q1 (category mismatch): Lens<C>.read is per-Behavior; emission
provenance is per-emitted-line. 4 options surfaced — (a) per-Behavior
Lens-compatible / (b) per-line instrumentation NOT a lens / (c)
withdraw + re-canvas / (d) Mgr-surface both substrates distinct.
Mgr recommends (d) if visualization is load-bearing; (a) suffices
if per-Behavior aggregate works for the slide. Brian-channel
sub-question surfaced.

Q2 (fold-rule enumerability): T-Rule-Enumeration substrate-fact-
introduction is prerequisite for every Q1 path (rust_target.rs uses
inline &str template names; rules not enumerable). Mgr recommends
parallel-dispatch with Q1 deliberation — satisfies Brian's ASAP
framing while shape ratifies.

Q3 (§1.8 ledger retarget): #89 already taken by T-LAS; new cluster
location follows Q1 disposition.

Director ratification ask + Brian-channel sub-question surfaced.
PR #1902 close-superseded post-ratification.

* briefs: reconcile Compose<...> slot-1 spellings to algebraic-concept names per Q-MC sub-decision 3

Address cursor NON-BLOCKING on PR #1889 sha 2b49b30: S3 Phase-2
brief mixed Compose<AbelianGroup, ...> with Compose<Int, ...>; S9
Phase-1 Step 3 used Compose<AbelianGroup, ...> + Compose<CommutativeSemiring,
...>; S9 Phase-2 used Compose<ApproximateField<Real>, ...>. All wrong
per Q-MC sub-decision 3 critical correction at gunbc#828
#issuecomment-4385530115:

  "prior phrasing Compose<AbelianGroup, MachineWidth<64>> was wrong
  — AbelianGroup<T> is a witness shape over carrier T, not a carrier
  constructor; bare AbelianGroup in slot-1 composes witness rather
  than concept."

Slot-1 is the fully-applied algebraic-concept name:
- Int<N>  = Compose<Int,  MachineWidth<N>>   (Int = AbelianGroup<GroupCompletion<Nat>>)
- UInt<N> = Compose<UInt, MachineWidth<N>>   (UInt = CommutativeSemiring<Nat>)
- Real<N> = Compose<Real, MachineWidth<N>>   (Real = ApproximateField<Rational>)

Phase-2 Float brief also retargets user-facing surface from Float<N>
to Real<N> (Float is target-language name for the Rust primitive;
Real is the algebraic-concept name per Q-MC sub-decision 3 example).

* s9-p1-s3 brief: scope Deliverable 4 to producer-side verification (defer demonstration to Grounding G2)

Address Codex BLOCKING (line 82 inline + bundled review): brief
claimed end-to-end Int<32> → Rust i32 round-trip in Acceptance
while Deliverable 3 said lowering rules belong to Grounding G2
follow-on. Internal contradiction.

Reframe per Director bundled-scope discipline (gunbc#1739
#issuecomment-4392225548 — parallel infrastructure DISALLOWED
same-PR):

- Deliverable 4: producer-side substrate-axis verification only
  (type-check + carrier acceptance + bootstrap snapshot/manifest
  hold). NO end-to-end Rust emission in this PR.
- §1.8 #67 numeric_construction_demonstration receipts split:
  producer half here (entries exist), consumer half on Grounding
  G2 PR (full Int<32> → Rust i32 round-trip).
- Same-PR cross-program co-author available if Substrate Mgr
  coordinates with Grounding Mgr at dispatch; default is split.

* fix(briefs): retire INVARIANTS.md line-number cites in r3-426 brief

Per codex review on PR #1782 (sha c2512cde): the new briefs
introduced fresh `INVARIANTS.md:<line>` citations — the same
stale-line-anchor shape the :425 sweep brief itself names as needing
dissolution. Replaces four line-number references in
r3-426-sfp-subdoc-rename-and-author-worker.md (lines 16, 28, 58, 85)
with prose-anchored locators citing the section anchor + bullet text.

The other PB-lane briefs codex flagged (r3-pb-runtime-equivalence-
corpus-seed-audit.md, r3-pb-t-fixedpoint-worker.md) belong to
neat-bear-351's lane and are not in this PR's scope; will route
separately.

* fix(briefs): correct L6 type count + r3-435 dual-path retirement receipt

Per openai-pro review on PR #1782 (sha c2512cde):

1. L6 brief said acceptance ratchet asserts "five types" exist but
   declares six (ShapeATarget, FormAxis, BehaviorAxis,
   MethodTemplateContractKey, EmissionCell, EmissionPathProjection).
   Updated both occurrences to enumerate all six explicitly.

2. r3-435 brief authorized both Path A (typed-AST reader, deletes
   IntegrationRsScan) and Path B (scanner widening with Char state),
   but retirement receipt language only covered Path B. Updated
   ROADMAP/ledger retirement and authority-audit step 5 to cover
   both authorized dissolution paths.

* fix(briefs): L6 second 'five types' site + T-E-P lookup-gate authority

Per cursor review on PR #1782 (sha 2072b986):

1. L6 brief acceptance bullet at :131 still said "five types" while
   the parenthetical and the Slice step at :117 said six. The prior
   fix only caught one of two sites; corrected the second.

2. T-E-P brief `e_p_call_pattern_lookup_authoritative` acceptance
   named only `lower_call_pattern` as "the only route from call
   site to LoweringTarget" — but Phase 2 explicitly requires
   lenses route through `per_call_pattern_at` (the L-7 single-
   authority lookup), NOT `lower_call_pattern` (compiler-internal).
   Acceptance text rewritten to name `per_call_pattern_at` as the
   consumer-facing gate and clarify `lower_call_pattern`'s
   internal-only scope.

* fix(briefs): strengthen L6 ratchet from count-parity to per-row bijection

Per openai-pro REQUEST_CHANGES on PR #1782 (sha 2072b986): the L6
acceptance ratchet asserted only row-count parity between
emission_path_projections and the union of MethodTemplateContract
rows. Count parity permits duplicate projection keys and missing
source rows — the bridge from list-non-empty proxy to per-row
projection would not be mechanically proven. The whole point of
introducing MethodTemplateContractKey { target, dag_method } is to
provide 1:1 row identity.

Rewrites the ratchet to assert per-row bijection: every
MethodTemplateContract source row has exactly one matching
EmissionPathProjection row by key; every projection key resolves
to exactly one source row; duplicate projection keys fail closed.

(The other openai-pro BLOCKING finding — T-E-P
e_p_call_pattern_lookup_authoritative naming the wrong authority
— was already fixed at 6282a0704; the review citation was against
the pre-fix sha 2072b986.)

* fix(briefs): split L6 ratchet into slice-active vs deferred-activation gates

Per BLOCKING inline review on PR #1782 at d92459423: the prior
bijection ratchet was unsatisfiable as authored. The
*_method_template_contracts lists at HEAD (rust/python/go) are
non-empty; shipping emission_path_projections: [] alongside a
strict bijection requirement means the bijection cannot pass when
the slice lands — source rows would be uncovered. Prior text
incorrectly said "vacuously true on the empty source set" — the
SOURCE set isn't empty, only the projection set is.

Splits the ratchet into two gate categories:
- Slice-active gates: types/data shape exist + empty-state
  predicate (emission_path_projections == []).
- Deferred-activation gate: per-row key bijection, authored as a
  test scaffold by this slice but #[ignore]'d (or feature-gated
  on len > 0) until Grounding's follow-up populates rows. On
  activation, asserts the bijection over the populated set.

This honors P1 doc faithfulness: the slice's acceptance contract
is satisfiable as authored, and the bijection becomes the
load-bearing gate the row-population PR satisfies.

* fix(briefs): require L6 bootstrap enrollment to honor P2 facts-flow-forward

Per BLOCKING inline review on PR #1782 at L6:34: the slice authored
src/v3/std/cross_target_coverage.dag but never required enrolling
it in the bootstrap/load authority. Without enrollment the file
is dead-letter on disk and EmissionPathProjection can be absent
from the downstream Dag — silent P2 facts-flow-forward violation.

Adds a new Slice step 2 requiring a cross_target_coverage field
on BootstrapFixtures in src/v3/std/extdeps_bootstrap_fixtures.dag
mirroring the *_method_template_contracts enrollment pattern, plus
a loader-visibility ratchet. Renumbers subsequent Slice steps.
Adds matching Acceptance bullet.

* docs(briefs): normalize Practice 4 citation in S3 brief per codex review

Codex review on PR #1782 (sha 2614217e) flagged stale citation
"Practice 4 (Step 4 of the type-introduction checklist)" in
S3 brief — no such checklist step exists in the pinned rubric.

Live rule per docs/modeling-discipline.md:131-134 is the "What to
check" checkpoint-comment requirement under Practice 4 (coproduct
dissolution). Updated the S3 reference to cite that line directly
and drop the stale "Step 4 of type-introduction checklist" wording.

S2/S8/S9 already use bare "Practice 4" without the stale steps wording.
S1 (committed earlier today) does not contain the stale phrase.
S6 (pre-existing brief flagged by reviewer as carrying the same
pattern) is out of this branch's scope; flag for separate paydown.

* docs(briefs): sweep stale Practice 4 citations corpus-wide

Codex review on PR #1782 flagged the stale "Step 4 of the
type-introduction checklist" wording — no such checklist exists in
docs/modeling-discipline.md. The live rule is the "What to check"
checkpoint-comment requirement under Practice 4 (coproduct
dissolution) at docs/modeling-discipline.md:131.

Sweep across docs/ found 2 additional briefs carrying the stale
phrasing (S3 fixed previously at 9db003d40):

- docs/briefs/r3-l6-emission-path-projection-substrate-worker.md
- docs/briefs/r3-x1b-s1-transform-dispatch-substrate-worker.md

Both updated to cite the live rule directly. Verified zero
remaining "type-introduction checklist" or "Step 4 of the"
references in docs/ tree.

* docs(briefs): add Practice 4 citation discipline note to authoring checklist

Per parent inbox status flag at gunbc#828 #issuecomment-4385346221:
add a Citation discipline section to brief-authoring-checklist.md
naming the correct shape — Practice 4 (coproduct dissolution) +
"What to check" rule at docs/modeling-discipline.md:131 — and
calling out the stale "Step 4 of the type-introduction checklist"
phrasing as a failure mode. References the corpus sweep at
2dc92f34f.

Prevents future briefs that copy old templates from re-introducing
the stale citation pattern.

* docs(r3): cascade work post-Director ratification — S1 worker, R4 routing, Unit/Quantity canvas

Per Director ratification at gunbc#828 inbox response 2026-05-06
(zesty-bear-812):

1. S1 Q1+Q2 RATIFIED → author S1 gap-test representative worker brief
   (`r3-substrate-s1-gap-test-representative-worker.md`). Dispatchable
   on T-E-P Phase 1 + E6-G0d landing; closes ledger row #61.

2. S2 Q2 RATIFIED (option-(b) T-LBP narrowing) + S3 + S8 deferrals →
   R4 carve-out routing ledger (`docs/r4-carve-out-routing.md`).
   Captures C1 (parallelism lens), C2 (effect_enum lens), C3
   (register narrowing), C4 (deferred MachineConstraint axes),
   C5 (rounding-mode product extension), C6 (Unit/Quantity).
   Cascade messages to Verification / Grounding / Debt-Paydown Mgrs.

3. S9 Phase-3 dimensional refinement boundary → Unit/Quantity carrier
   canvas (`r3-substrate-s9-unit-quantity-carrier-canvas.md`).
   Surfaces Q-Unit-1..5 for Director ratification: carrier name,
   2-axis vs 3-axis Phase-1, Duration/Seconds collapse, Refined
   composition order, Practice 4 classification.

Updates §1.8 ledger receipts for carved items; R3 closure receipts
treat carved items as explicitly-deferred (not drift).

* docs(briefs): citation-discipline fix-forward — anchors/quotes, not line numbers

Director redirect at gunbc#828 #issuecomment-... noted the citation
paydown's replacement form (`docs/modeling-discipline.md:131`) is the
same drift class as the original fabricated-step error. Bare line
numbers shift silently on any doc edit above the cited line.

Generalized fix:
- brief-authoring-checklist.md "Citation discipline" section
  rewritten to prohibit bare line-numbers across ALL cross-doc
  references (modeling-discipline.md, r3-program-plan.md,
  r3-structure.md, INVARIANTS.md, MODELING.md, etc.). Use section
  anchors (#section-name) or rule-text quotes.
- 3 briefs that swapped in :131 (S3, S6, X1B) re-converted:
  - docs/modeling-discipline.md#4-coproduct-dissolution anchor
  - "What to check" rule quoted inline (self-contained)

Brief-authoring-checklist failure-mode section names both vectors
(fabricated step + bare line numbers) and references both sweep
commits in audit trail.

Broader cross-doc citation sweep across briefs I authored on this
branch (frontmatter authority-docs lists, body prose) is recommended
per Director note — flagging as separate paydown task; this commit
closes the immediate recurrence vector.

* docs(briefs): fix unfaithful Int=AbelianGroup<Nat> + sweep stale 'Step 4' refs

Per openai-pro review on PR #1782 sha 0ecd4818 (gunbc#1782 #...):

BLOCKING fix (P1 modeling faithfulness):
- S9 + S3 directed workers to model `Int = AbelianGroup<Nat>`,
  but Nat is not an Abelian-group carrier (additive inverses
  not representable). Reframed:
  - `Int` is the additive Abelian group on integers (carrier Z);
    `Nat` is a commutative monoid under addition.
  - Algebraic relationship is **explicit group-completion**:
    `Int ≡ GroupCompletion<CommutativeMonoid<Nat>>` — NOT
    `AbelianGroup<Nat>` parameterization.
  - Worker either models `Int` directly as `AbelianGroup`
    (terminal Abelian-group instance) OR introduces explicit
    `GroupCompletion<M>` substrate carrier; decision lands in
    Phase-1 PR per P1 procedure.
- S3 cross-reference + Phase-4 algebra-axis preservation note
  reframed accordingly.

NON-BLOCKING in-PR cleanup (Practice 4 citation discipline):
- 6 briefs still carrying stale 'Practice 4 Step 4' wording
  (r3-coproduct-1/2/3, r3-l6, r3-t-e-p, r3-x1b) updated to use
  the section anchor (`docs/modeling-discipline.md#4-coproduct-dissolution`)
  + inline rule-text quote ("What to check") form per the
  citation discipline established in `b4cae5299`.

Closes both findings from openai-pro review.

* docs(briefs): Q-Unit-1..5 RATIFIED — apply Scale.Unit→One rename + ratification banner

Director ratified Q-Unit-1..5 at gunbc#828 #issuecomment-... 2026-05-06
(zesty-bear-812). All 5 questions ratified; one rename required:

- Scale enum's `Unit` value collides with outer `Unit<Q, S>` carrier
  name (`Unit<Time, Unit>` is shadowing-confusing). Rename to `One`.
- Duration ≡ Unit<Time, One> (collapses with Seconds per Q-Unit-3).
- Milliseconds ≡ Unit<Time, Milli>.

Canvas updated:
- Top-level RATIFICATION banner records all 5 ratifications + rename
- Scale enum: `Unit` → `One` (with inline rename receipt)
- Sketch product expansions use `Unit<Time, One>` / `Unit<Time, Milli>`
- Phase-3 reframe table products updated
- Q-Unit-3 prose collapse reference updated

Subsequent worker brief authoring (Unit/Quantity carrier landing
post-prerequisite) inherits the renamed shape.

* docs(briefs): Unit/Quantity carrier worker brief — Q-Unit-1..5 RATIFIED

Worker brief consumes the ratified Unit/Quantity canvas
(`5f22fd06e` ratification banner). Phase-1 lands `Unit<Q, S>` +
`Quantity` + `Scale` declarations at the ratified shape (Scale's
`One` value per Q-Unit-1 rename). Phase-2 reframes S9 Phase-3
dimensional refinements (Duration / Seconds / Milliseconds) to
outer-Refined / inner-Unit composition per Q-Unit-4 RATIFIED.
EpochMs deferred to R4 C6 (Aspect-axis follow-up).

Practice 4 marks pre-determined per Q-Unit-5: `Unit<Q, S>` 🟢
PRIMITIVE; `Quantity` + `Scale` 🟡 SCAFFOLD with "consumed by ≥1
emission rule" dissolution trigger.

Cross-program handoff to Grounding Mgr (#1745) for dimensional
emission consumption documented.

Worker pin TBD — dispatchable when idle pool refreshes.

* docs(briefs): S9 Phase-1 reframed — Int landed at #1466; UInt-only migration

Per proud-lynx-311 dispatch ack at gunbc#1739 #issuecomment-...
2026-05-06: re-grep at HEAD revealed substrate state diverges
materially from S9 brief's "Option A vs B decide" framing.

Reality check at HEAD:
- `dsl/std/integer.dag:55` already carries
  `type Int = AbelianGroup<GroupCompletion<Nat>>` per Slice 3 PR
  #1466 / commit `4ba0a6d04`. Single-authority Q6 audit doc at
  `docs/audit/t-numeric-construction-group-completion-6q.md`
  ratified this shape and explicitly rejected the compact form.
- `dsl/std/integer.dag:56` still on legacy `type UInt = UInt64`
  alias; UInt migration is the actual Phase-1 worker scope.

Brief Phase-1 step 1 reframed: Int landing acknowledged; worker
confirms HEAD match. Phase-1 step 2 reframed: UInt migration
target named (`type UInt = CommutativeMonoid<Nat>`); fixed-width
rows preserved per existing legacy-rows policy.

Historical Option A vs B framing kept as note (superseded).

Confirmed S9 dispatch ack from worker; UInt-only Phase-1 PR is
in-scope. Emission entries deferred per S3 (valiant-ant-72
pre-landing); Phase-2 deferred per S8 (quiet-boar-160 pre-landing).

* docs(briefs): fix two BLOCKING citation drift items per codex review

Codex review on PR #1782 sha 5f22fd06 flagged two authority-receipt
gaps:

1. brief-authoring-checklist.md:118 — `<this-commit>` placeholder in
   the failure-mode section was unverifiable post-merge. Replaced
   with `b4cae5299` (the actual anchor/quote conversion commit).

2. r3-378-http-path-helper-fail-open-worker.md:84 — `INVARIANTS.md
   C-8 fail-closed` cited without anchor or rule-text quote, in
   violation of the citation discipline added in this PR.
   Converted to `INVARIANTS.md#p3-fail-closed` (P3 heading anchor)
   + inline rule-text quote naming P3 + C-8.

PR's own discipline now consistently applied across the diff.

* docs(briefs): sweep bare .md:NNN citations in Substrate-Mgr-authored briefs

Per Director recommendation in citation-discipline thread (gunbc#828
follow-on): bare line-number references drift silently. Swept 19
remaining instances across 5 briefs I authored on this branch:

- docs/briefs/r3-substrate-s1-q-class-2-chain-break-gap-test-canvas.md
- docs/briefs/r3-substrate-s1-gap-test-representative-worker.md
- docs/briefs/r3-substrate-s2-t-lbp-scope-calibration-canvas.md
- docs/briefs/r3-substrate-s3-machine-constraint-carrier-worker.md

Conversion: bare `file.md:NNN` → `file.md §"Section name"` form.
Stable; survives doc edits; human-readable. Section names per
HEAD heading audit.

Verification: `grep -nE '.md:[0-9]+' docs/briefs/r3-substrate-*.md
docs/r4-carve-out-routing.md` returns zero results in
Substrate-Mgr-authored scope.

Broader corpus scope (~232 references across non-Substrate briefs)
remains as separate paydown task.

* docs(briefs): fix BLOCKING + NON-BLOCKING items per openai-pro review on a462f007

Three findings addressed; 2 BLOCKING + 1 NON-BLOCKING:

BLOCKING — R3/R4 dual authority for Unit/Quantity carrier:
R4 carve-out C6 narrowed from "Unit/Quantity carrier landing"
(deferred all of it) to **"Aspect-axis (PointKind) follow-on
for EpochMs and instant/rate-shaped refinements only"**. The
2-axis Measure<Q,S> carrier landing IS in R3 per Q-Unit-1..5
RATIFIED; only the Aspect axis (PointKind = Magnitude | Instant
| Rate) carves to R4. Cascade-message C6 reference + R4 program-
plan input list updated to match. Cross-Mgr message clarifies
Grounding consumes 2-axis dimensional refinements in R3.

BLOCKING — Locked design partially applied (Scale.Unit→One
rename in canvas alternate-sketch sections):
- Canvas line 105-108 alternate sketch ("Open question: Instant
  vs Duration axis") still used pre-rename `Unit` Scale value;
  added pre-ratification disclaimer marking the section as
  deferred to R4 C6 + noting `Unit` is pre-rename
- Canvas line 163 Q-Unit-3 collapse note: `Scale = Unit` → `Scale = One`

(BLOCKING — bare line-numbers in S1 canvas frontmatter): NOT
APPLICABLE — already fixed at sweep commit 127287a66 prior to
review; reviewer was on sha a462f007 pre-sweep.

NON-BLOCKING — placeholder receipts:
- brief-authoring-checklist.md `#issuecomment-...` → concrete ID
  4385393971 (Director's anchor-discipline reply)
- r3-substrate-unit-quantity-carrier-worker.md (3 occurrences)
  + canvas RATIFICATION banner: `#issuecomment-...` → concrete ID
  4385412256 (Q-Unit ratification reply)
- `<this-commit>` placeholder in checklist already fixed at 5be1c99f2

Verification: zero `#issuecomment-...` or `<this-commit>` placeholders
in docs/briefs/ + docs/r4-carve-out-routing.md.

* docs(briefs): codex BLOCKING review fixes — Practice 4 source-level + policy scope

Three BLOCKING findings on PR #1782 (codex sha b913e2f4):

1. **Citation-discipline policy scope**: addressed by scoping
   the rule prospectively to briefs landing after the policy
   commit (`b4cae5299`). Pre-existing corpus references are
   flagged as paydown but NOT individually blocking; coordinated
   single-PR sweep is the right paydown shape. Substrate-Mgr scope
   already swept at `127287a66`.

2. **R4 C6 reconciliation**: already fixed at `6e5a5481a` (R4 C6
   narrowed to Aspect-axis follow-on for EpochMs only; 2-axis
   carrier landing IS in R3). Codex sha b913e2f4 was pre-fix.

3. **Practice 4 source-level vs PR-body conflation**: corrected.
   Acceptance bullet for Unit/Quantity worker brief now requires
   inline checkpoint comments on the LIVE declarations in
   `dsl/std/units.dag` (load-bearing artifact per
   `docs/modeling-discipline.md#4-coproduct-dissolution` "What to
   check"). PR-body summary is supplementary, not substitute.

Closes the review's reconciliation gates.

* docs(briefs): absorb Q-MachineConstraint + Q-Unit-1-Recanvas ratifications

Two major Director ratifications absorbed:

1. Q-MachineConstraint-Carrier RATIFIED at gunbc#828
   #issuecomment-4385530115 (Brian directive 2026-05-06: "universal
   substrate, ratify defaults"; PR #1817 queued). 6 sub-decisions:
   - MachineWidth<bits> only for R3; defer RegisterClass / EndianMode
     / Alignment / signedness post-R3
   - Parametric Compose<Algebra, MachineConstraint> type-level
     interaction shape (lookup-maps REJECTED — AlgebraMachineProduct
     record-keyed table form retracted)
   - Int<64> ≡ Compose<AbelianGroup, MachineWidth<64>> (algebra-side
     options A and B preserve interaction semantics)
   - Real<64> ≡ Compose<ApproximateField<Rational>, MachineWidth<64>>
     (algebra approx + machine approx as independent composing axes)
   - ≥3 pairs is minimum, not target
   - UNIVERSAL substrate: every target carries machine-constraint
     facts; targets without native machine-width semantics handle
     omission at Grounding-level discharge (target-conditioned
     lowering NOT target-conditioned substrate)

   Reframed: S3 brief Phase-1, S3 Phase-3/4 emission entries,
   S8 Phase-1/2/3 (ApproximateField<Real> → ApproximateField<Rational>;
   AlgebraMachineProduct → Compose<...>), S9 emission entries.

2. Q-Unit-1-Recanvas RATIFIED Measure<Q, S> at gunbc#828
   #issuecomment-4385539791. valiant-ibex-312's substrate-state
   grep caught Unit<Q, S> collision with kernel Unit at
   dsl/std/types.dag:176; Director ratified Measure<Q, S> as
   outer carrier name (conventional in scientific computing;

* docs(briefs): S11 Slice C worker brief — ROADMAP :425 retirement post-#1801

Cascade-clearance trigger fired post-#1801 (Slice B) merge
2026-05-06. S11 brief authored per B1 RATIFIED prose+regen
bundling discipline.

Phase 1: per-file edits across the post-A+B residual list (~10
files per smart-ram-167's Slice B post-rebase enumeration);
anchor + rule-text-quote pattern per current citation discipline;
bootstrap regen in same PR (no split).

Phase 2: ROADMAP :425 row PARTIAL → Retired with 3-slice receipt;
Q-Slice-C-Retirement-Receipt resolution.

Worker pin smart-ram-167 (#1759) — Slice B precedent owner.
Dispatch packet sent separately to #1759.

* docs(briefs): Q-Refined-Phantom-Composition (c) RATIFIED — defer literal Refined form

Director ratified option (c) at gunbc#828 #issuecomment-... 2026-05-06:
drop `non_negative` predicate at Measure (phantom) layer; rely on
`Quantity = Time` tagging for non-negative-magnitude semantics.

Q-Unit-4 outer-Refined / inner-Measure composition is preserved as
**conceptual model**; the literal `Refined<Measure<...>, predicate>`
form is **deferred to value-typed-integration follow-up** when
substrate gains Refined<> as first-class type expression and
dimensional refinements get value-typed integration.

Updates:
- Canvas RATIFICATION banner Q-Unit-4 row reframed to "conceptual
  model; literal form deferred"
- Canvas Phase-3 reframe table: Duration / Milliseconds drop the
  Refined<...> wrapper; rely on Quantity tag
- Worker brief Phase-2 prose + reframe table + Acceptance bullet
  all reflect deferred-literal-form posture

valiant-ibex-312 unblocked to proceed with Phase-2 (Grounding
handoff doc) per the (c)-shaped Acceptance.

* docs(briefs): S12 F2 + F8 doc-sharpening worker brief — post-#1820 cascade

#1820 (Slice C) merged 2026-05-06; ROADMAP :425 row Retired closes
the prose-reference paydown program. S12 cascade-clearance trigger
fires per B6 RATIFIED single bundled Mgr-tier doc-sharpening PR.

Scope: F2 (.v3 filename-suffix grammar dispatch) + F8 (bootstrap
load-order/exclusion authority) — single bundled PR per B6.
Cross-program coordination with PB Mgr (#1742) per design schedule
§3 P5 (comment-only OR co-author; no duplicate PR).

Worker pin smart-ram-167 (#1759) — Slice C precedent owner;
pattern-familiar with prose+regen bundling discipline. Dispatch

* docs(briefs): S9 brief — UInt landed via #1818; algebra label corrected to CommutativeSemiring

Per proud-lynx-311 merge report at gunbc#1746 #issuecomment-...
2026-05-06: PR #1818 landed `type UInt = Nat` after codex BLOCKING
review on initial `CommutativeMonoid<Nat>` form (P2 facts-flow-forward
violation — wrap projects out Nat's multiplicative monoid + identity 1).

Final landed form preserves full `CommutativeSemiring<Magnitude>`
surface — Nat IS a commutative semiring (addition + multiplication
+ 0 + 1). Algebra-side label for UInt is CommutativeSemiring, NOT
CommutativeMonoid (corrects my earlier dispatch labeling).

S9 Phase-1 step 2 marked LANDED with merge ref. Phase-1 step 3
emission entries reframed:
- Int<N> ≡ Compose<AbelianGroup, MachineWidth<N>>
- UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>>

Worker discipline + reviewer caught a substrate-state error in my
brief framing; brief now matches landed reality.

* docs(briefs): fix contradictory (c) guidance in Unit/Quantity worker brief

Codex BLOCKING review on PR #1825 sha 1bce0418 caught a real
contradiction: brief Phase-2 prose at lines 115-118 stated
"predicates do NOT attach at the Measure (phantom) layer" per
Q-Refined-Phantom-Composition (c) RATIFIED, but immediately
following paragraph at lines 130-132 still said "Refined predicate
non_negative applies at the Measure-typed level" — left over from
the original Q-Unit-4 framing.

Updated lines 130-137 to consistently apply (c) shape: predicates
deferred to value-typed-integration follow-up; dimensional semantics
ride on Quantity tag at Measure layer; worker authors 3 in-scope
refinements WITHOUT predicate at this layer.

P2 boundary discipline restored: brief now gives single-authority
guidance for Phase-2 substrate landing.

* docs(briefs): name predicate authority + concretize ratification ID — codex BLOCKING

Codex BLOCKING review on PR #1825 sha 32541a56:

1. (BLOCKING) Q-Refined-Phantom-Composition (c) ratification deferred
   phantom-carrier predicates without naming the value-level predicate
   authority. Updated canvas Q-Unit-4 RATIFICATION row to explicitly
   name: 'predicates re-attach at value-typed Int/UInt level via
   where-sugar (e.g., range(min: 0) per current dsl/std/types.dag
   precedent)' when value-typed integration lands.

2. (BLOCKING) Worker brief option-c reframe didn't sweep the audit
   receipt §5 (Carrier dissolves the bridge). Updated to consistently
   apply (c) shape — dimensional semantics ride on Quantity tag at
   Measure layer; value-level predicate authority deferred; until
   then, range/gt_zero constraints attach at value-typed Int/UInt
   via where-sugar per dsl/std/types.dag convention.

3. (NON-BLOCKING) Canvas had #issuecomment-... placeholder for the
   (c) ratification message ID. Replaced with concrete
   #issuecomment-4385687075 per dashboard relay header.

Brief now names a single value-level authority (Int/UInt where-sugar)
for value-range facts; phantom-layer Quantity tag carries only
dimensional semantics. P2 boundary discipline maintained.

* docs(briefs): S12 RETIRED per Director option (2) ratification

Director ratified option (2) at gunbc#828 #issuecomment-4385873...
2026-05-06 post smart-ram-167's substrate-state STOP-AND-ESCALATE:

- F2 absorbed by 2026-05-04 routing + #1662 closure
  (`Result/DivError span.file-keyed` retired)
- F8 topical concerns distributed across live rows
  (Class 5 Gap 3 `bootstrap.rs::std_fixtures()`; Character-level
  load-set / bootstrap; Filename-sentinel-bridges) with own owners
- Doc-discipline goals absorbed by per-Mgr citation paydown
  routing at gunbc#828 #issuecomment-4385583247

Frontmatter updated to RETIRED with absorption receipt. Worker
(smart-ram-167) pin freed.

Director-side acknowledgment of Substrate Mgr's option (2) recommendation:
"Substrate Mgr's option (2) recommendation is the right move
structurally. Most Mgrs default to 'synthesize work to fill the brief'
when canvas-vs-HEAD mismatch surfaces. Recommending retirement when
the work is genuinely absorbed is harder discipline."

* docs(briefs): S7 PR-F (BoundDeclaration consumer + ReferenceModel<T>) worker brief

Per cascade-clearance trigger fired post-#1782 merge 2026-05-06.
loyal-wolf-828 (#1764) acknowledged S7 dispatch with substrate-state
pre-flight grep (gunbc#1764 #issuecomment-4385872...) and surfaced
await-brief posture. This brief satisfies that prerequisite.

Worker pre-flight inventory absorbed:
- BoundDeclaration substrate landed (substrate.dag StaticBound +
  PlatformDependent); partial BoundDeclarationView consumer in
  fold.rs (ScratchIntExamples scope; doc-explicit partial)
- ReferenceModel<T> NOT yet in dsl/std/ (substrate-fact-introduction
  required; design-emission-model.md §Q2 framing)

Phase-1: BoundDeclaration consumer broadening to full
design-emission-model.md surface (u128 / isize / usize / walker
arms / pilot mirror).

Phase-2: ReferenceModel<T> P1 substrate-fact-introduction with
DFS-of-concept-DAG + Practice 4 in-source checkpoint comment +
named consumer demand (Grounding G1).

Phase-3: cross-program handoff to Grounding Mgr (#1745) for
G1 (T-Ground-Rust Phase 1).

Closure predicate: unblocks Grounding T-Ground-Rust Phase 1.
Worker pin loyal-wolf-828 holds; dispatch fires immediately
on this brief landing.

* docs(briefs): S9 Slice 2.5 — predicate-registry + PB-1 shim retirement (Path 3 RATIFIED)

Director ratified Path 3 at gunbc#828 #issuecomment-4390333451
post proud-lynx-311's pre-flight DFS at gunbc#1746 #issuecomment-4390253616.

Brief reframes Slice 2.5 from S-sized (primitive + 1 consumer) to
L-sized (predicate registry + PB-1 shim retirement). 5 deliverables:
1. gt_zero primitive predicate
2. Predicate registry infrastructure (resolver-side substrate-fact-introduction)
3. PB-1 shim retirement (span.file=='dsl/std/types.dag' special case dissolves)
4. Migration of existing types.dag predicates (range, pattern, etc.)
5. PositiveInt = Refined<Nat, gt_zero> consumer update

Per Director hard scope bars: no parallel predicate-resolution path;
no per-call-site special-casing; PB-1 shim retirement non-negotiable
in same slice. Single PR per Path 3 RATIFIED.

Discipline anchors: feedback_construction_over_ratchets (PB-1 shim
is bridge); feedback_dissolve_bridges (registry is structural fix);
feedback_no_textual_enforcement_bridges (file-path special-case is
anti-pattern shape); P1 substrate-fact-introduction procedure.

Worker pin proud-lynx-311 — Director pre-cleared on pre-flight DFS
context. PR #1840 (partial Slice 2 — NonNegativeInt = Nat) MERGED
at 16:54Z; Slice 2.5 dispatchable immediately on this brief landing.

* docs(briefs): Slice 2.5 audit receipt — Mgr independent grep parallel-verifies worker DFS

Codex BLOCKING review on PR #1845 sha 2d230949 flagged: external PR
receipt absorbed as live substrate state without re-grepping local
std declarations at brief authoring time. Authority receipt §1
cited proud-lynx-311's pre-flight DFS as authority but didn't
record Mgr-side independent verification.

Updated audit receipt §1 + §4 to record Mgr's independent grep at
HEAD as parallel verification:
- gt_zero zero matches in dsl/std/ + src/v3/ (verified)
- NonNegativeInt = Nat at dsl/std/integer.dag:133 (#1840 land)
- PositiveInt = Int where range(min: 1) at dsl/std/types.dag:255
- PB-1 shim doc-block confirms bridge-text framing
- Predicate registry confirmed not present

Worker DFS remains the dispatch-time discipline (substrate-state
grep at dispatch); Mgr's independent grep is parallel verification,
not substitute. Per Director's pattern note at gunbc#828
#issuecomment-4390199218 + #issuecomment-4390333451: dispatch-packet
authoring discipline includes Mgr-side substrate-state-grep, not
just relay of worker findings.

* docs(briefs): Slice 2.5 brief — Int extensibility scope-bound; lower.rs cites anchored

openai-pro REQUEST_CHANGES on PR #1845 sha 2d230949 flagged 2 issues:

BLOCKING — P1 modeling faithfulness / substrate scope leak:
`gt_zero` Int-side extensibility was left to 'worker judgment if
generalization cheap'. Per feedback_construction_over_ratchets:
don't speculatively extend predicate-carrier compatibility ahead
of named consumer demand. Reframed to **EXPLICITLY OUT-OF-SCOPE**
for Slice 2.5; Nat-only registration. Future Int-side consumer
surfaces as separate substrate-fact-introduction (P1 procedure)
brief with own consumer-demand receipt.

NON-BLOCKING — citation discipline self-violation:
3 instances of bare `lower.rs:821-835` line-range citations
contradict the brief's own 'no bare :NNN' requirement at line 211.
Converted to function-name anchored form:
`src/v3/compiler/src/lower.rs` (`lower_type_alias_refinements_phase` doc-block).

Both findings absorbed; no parallel scope ambiguity remains;
brief now self-consistent on citation discipline.

* WIP: R3 Substrate

* docs(briefs): Slice 2.5 brief — audit-receipt cites converted to declaration-name anchors

cursor APPROVE_WITH_COMMENTS on PR #1845 sha ebf6ac12 noted citation

Converted to declaration-name-anchored form:

* docs(briefs): Slice 2.5 brief — Path (a) RATIFIED carrier+argument contract verification

Director Path (a) RATIFIED at gunbc#828 #issuecomment-4390760353
(triage) + #issuecomment-4390794121 (convergence ack):
predicate-body lowering with carrier+argument contract
verification at lower-time IN SAME SLICE. Placeholder semantics
REMOVED from registry path.

Codex REQUEST_CHANGES surfaced that registered-predicate-without-
contract = silent acceptance per feedback_fail_closed_discipline.
Brief reframe absorbs Path (a):

Hard scope bar #5 added:
- Same-slice carrier+argument-contract verification
- Mismatched carrier OR malformed argument → Diagnostic::ResolveError
- No 'named but not checked' path remains

Scope expansion section added (L → XL):
- Predicate-body lowering for all 7 registered predicates
- Per-predicate arg-shape validation
- Multi-session work acknowledged
- Carrier-check at 788d6acb4 retained; predicate-body builds on top

Acceptance bullets updated: gt_zero with arg-shape validation +
all 7 predicates with carrier+argument contract verification.

Director-pinned brief-authoring discipline: dissolution trigger
named in a brief authored as substrate-fact-introduction must
specify same-slice acceptance, not deferred follow-up. Otherwise
the brief encodes 'land bridge + defer dissolution' anti-pattern,
the same shape feedback_construction_over_ratchets warns against
at implementation layer applied at brief authoring layer.

This is the 11th miss this session — but the pattern surfacing it
(direct sweep + Codex REQUEST_CHANGES + Director ratification)
produces structural fixes that prevent the next miss class. Brief
revision is the structural recovery.

* docs(briefs): Slice 2.5 brief — Path 2 RATIFIED (Gap 1 discharge + Q-Regex carve-out)

Director Path 2 RATIFIED at gunbc#828 #issuecomment-4391985613
post Rung 3 STOP at gunbc#1746 #issuecomment-4391946213.

Path 2 narrowing of Path (a):
- gt_zero + range body synthesis already landed (5f3c40c3a)
- Gap 1 discharge mechanism: extends scalar-literal predicate
  evaluation at lower-time. L-class; lands SAME SLICE per
  same-slice-dissolution discipline
- non_empty + brand body synthesis: lands via Gap 1 discharge
- pattern / format / content: fail-closed-with-named-dep at
  user-code authoring layer (Diagnostic::ResolveError naming
  Q-Regex-Primitive). NOT placeholder; structural rejection
- PB-1 shim FULLY RETIRED per hard scope bar #3
- Q-Regex-Primitive carved as follow-on substrate-fact-introduction
  (XL substrate; not pre-authored per feedback_construction_over_ratchets)

Acceptance updated:
- 4 of 7 body-synthesized in same slice
- 3 of 7 fail-closed-with-named-dep (no placeholder semantics)
- Gap 1 discharge mechanism landed (no partial implementation)

Worker disposition: proud-lynx-311 continues Rung 3 with Gap 1
implementation + non_empty/brand body synthesis + pattern/format/
content fail-closed-with-named-dep diagnostic.

* docs(briefs): S9 Phase-1 Step 3 emission entries — Tier-1 brief authoring (1/5)

First Tier-1 brief landing post Director auto-nudge on assignment
#1858. Authored against Q-MachineConstraint sub-decisions ratified

- UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>> → Rust u32/u64/u128
- 6 concrete instantiations (≥3 minimum per sub-decision 5)
- Cross-program handoff to Grounding Mgr (#1745) for G2 emission consumption
- numeric_construction_demonstration Acceptance bullet (Int<32> round-trip);
  Real<64> half deferred to S9 Phase 2 / S8 Float cascade

Brief authored with substrate-state-grep discipline + same-slice-
dissolution discipline (no deferred trigger; demonstration in same
slice or explicitly carved). 5-question authority audit completed
in brief body.

Worker pin proud-lynx-311 (S9 holds); brief queues post-Slice-2.5
completion as natural follow-on.

Tier-1 brief queue progress:
- 1/5 authored (this brief)
- 4 remaining: S9 Phase-2 Float coordination; T-LBP complexity
  cementing; T-LBP cost cementing; S3 Phase-2 parser-grammar

* docs(briefs): S3 Phase-2 parser-grammar surface — Tier-1 brief 2/5

Authored per Director freed-pool pressure at gunbc#828
#issuecomment-4392095857 + Tier-1 brief-queue commitment.

Brief covers parser-grammar surface for Compose<Algebra, MachineConstraint>
interaction syntax post-#1856 (Phase-1 carrier slice landed):

- Phase 2.1: Parser surface per ratified Q-MachineConstraint-Grammar-Shape
- Phase 2.2: Bootstrap demonstrator with >=3 algebra*machine-axis pairs
- Phase 2.3: Class 1 5-criteria Pass receipt (criteria 1-4; criterion 5
  v2-oracle parity may carve)
- Phase 2.4: numeric_construction_demonstration co-receipt with S9 Phase-1
  Step 3 emission entries brief

Director ratification HOLDS on grammar bikeshed:
- Candidate A: Int @ Width<32> (annotation form)
- Candidate B: Int with MachineWidth<32> (with-form)
- Candidate C: Int<32> (positional generic — fits existing convention)
- Candidate D: Compose<AbelianGroup, MachineWidth<32>> (no parser change;
  type aliases provide convenience names)

Worker pin valiant-ant-72 holds (S3 Phase-1 precedent owner); freed-pool
until Director ratifies grammar shape.

Tier-1 brief queue progress: 2/5 authored (this brief + S9 Phase-1 Step 3).
Remaining: S9 Phase-2 Float coordination; T-LBP complexity cementing;
T-LBP cost cementing.

* docs(briefs): S3 Phase-2 brief — fix internal contradiction on Class 1 closure scope

Codex BLOCKING review on PR #1889 sha ec609b4a flagged real
contradiction:

- Provenance section claimed '5-criteria Pass closed' (line 229)
- Phase 2.3 said 'criterion 5 may queue separately' (line 154)
- STOP-AND-ESCALATE bullet 1 ratified 4-of-5 carve-out (line 181)

Updated Provenance to consistently state criteria 1-4 close in this
slice; criterion 5 (v2-oracle parity) cementing test may carve to
separate slice. Single 4-of-5 framing throughout. INVARIANTS.md
'Documentation Describes Live State' satisfied.

Per feedback_construction_over_ratchets: don't claim closure that
isn't structurally complete. 4-of-5 + named carve is the honest
shape; 5/5 only on cementing-test land.

- 4 predicates body-synthesize via Gap 1 (gt_zero / range / non_empty
  / brand)
- pattern / format / content STRUCTURALLY ABSENT from registry (not
  pending-with-placeholder); user-code where-clause produces
  Diagnostic::ResolveError naming Q-Regex-Primitive as separate
  substrate-fact-introduction follow-on
- ~12 types.dag refined-type declarations migrate to drop
  pattern/format/content where-clauses with inline-comment receipts
  pointing to Q-Regex restoration path; 1 extdep (sts_endpoint)
  adapts as needed
- PB-1 shim FULLY RETIRED — no exception, no preserved branch
- Q-Regex-Primitive as separate brief / worker pin / Director

Q1 (category mismatch): Lens<C>.read is per-Behavior; emission
provenance is per-emitted-line. 4 options surfaced — (a) per-Behavior
Lens-compatible / (b) per-line instrumentation NOT a lens / (c)
withdraw + re-canvas / (d) Mgr-surface both substrates distinct.
Mgr recommends (d) if visualization is load-bearing; (a) suffices
if per-Behavior aggregate works for the slide. Brian-channel
sub-question surfaced.

Q2 (fold-rule enumerability): T-Rule-Enumeration substrate-fact-
introduction is prerequisite for every Q1 path (rust_target.rs uses
inline &str template names; rules not enumerable). Mgr recommends
parallel-dispatch with Q1 deliberation — satisfies Brian's ASAP
framing while shape ratifies.

Q3 (§1.8 ledger retarget): #89 already taken by T-LAS; new cluster
location follows Q1 disposition.

Director ratification ask + Brian-channel sub-question surfaced.
PR #1902 close-superseded post-ratification.

* briefs: reconcile Compose<...> slot-1 spellings to algebraic-concept names per Q-MC sub-decision 3

Address cursor NON-BLOCKING on PR #1889 sha 2b49b30f: S3 Phase-2
brief mixed Compose<AbelianGroup, ...> with Compose<Int, ...>; S9
Phase-1 Step 3 used Compose<AbelianGroup, ...> + Compose<CommutativeSemiring,
...>; S9 Phase-2 used Compose<ApproximateField<Real>, ...>. All wrong
per Q-MC sub-decision 3 critical correction at gunbc#828
#issuecomment-4385530115:

  "prior phrasing Compose<AbelianGroup, MachineWidth<64>> was wrong
  — AbelianGroup<T> is a witness shape over carrier T, not a carrier
  constructor; bare AbelianGroup in slot-1 composes witness rather
  than concept."

Slot-1 is the fully-applied algebraic-concept name:
- Int<N>  = Compose<Int,  MachineWidth<N>>   (Int = AbelianGroup<GroupCompletion<Nat>>)
- UInt<N> = Compose<UInt, MachineWidth<N>>   (UInt = CommutativeSemiring<Nat>)
- Real<N> = Compose<Real, MachineWidth<N>>   (Real = ApproximateField<Rational>)

Phase-2 Float brief also retargets user-facing surface from Float<N>
to Real<N> (Float is target-language name for the Rust primitive;
Real is the algebraic-concept name per Q-MC sub-decision 3 example).

* s9-p1-s3 brief: scope Deliverable 4 to producer-side verification (defer demonstration to Grounding G2)

Address Codex BLOCKING (line 82 inline + bundled review): brief

while Deliverable 3 said lowering rules belong to Grounding G2
follow-on. Internal contradiction.

Reframe per Director bundled-scope discipline (gunbc#1739
#issuecomment-4392225548 — parallel infrastructure DISALLOWED
same-PR):

- Deliverable 4: producer-side substrate-axis verification only
  (type-check + carrier acceptance + bootstrap snapshot/manifest
  hold). NO end-to-end Rust emission in this PR.
- §1.8 #67 numeric_construction_demonstration receipts split:
  producer half here (entries exist), consumer half on Grounding
  G2 PR (full Int<32> → Rust i32 round-trip).
- Same-PR cross-program co-author available if Substrate Mgr
  coordinates with Grounding Mgr at dispatch; default is split.

* WIP: R3 Substrate

* briefs: address codex BLOCKING bundle (sha 2ed1046e) — record-form provenance + emit_model carrier alignment + T-Rule-Enumeration retirement flag

Three findings addressed:

1. Lens brief (Finding #1 — provenance shape conflates source vs rule
   attribution): replaced typed-sum EmissionOrigin with record
   EmissionProvenance { rule: EmissionRule [mandatory], source_span:
   Option<SourceSpan> [optional] }. Co-inhabitance is real (e.g.,
   #[derive(Debug)] line has both rule=derive_for_disj AND span
   attribution to Foo decl). Rule-mandatory enforces fail-closed
   structurally; Practice 4 N/A (record, not coproduct).

2. T-Rule-Enumeration brief (Finding #2 — rule authority lives in
   spec/rust.dag + v3.std.emit_model, not call-site strings): brief
   status flipped to FLAGGED FOR RETIREMENT. Same finding as
   smart-ram-167 STOP at gunbc#1759 #issuecomment-4392696623; Reading
   C surfaced to Director at gunbc#828 #issuecomment-4392780871.

3. Rust-primitive-full-coverage brief (Finding #3 — BoundDeclaration
   not wired into TargetIntegerInhabitanceBound row surface):
   reframed Deliverable 2 to target the actual carrier
   `v3.std.emit_model::TargetIntegerInhabitanceBound` (used by
   `TargetIntegerTypeInhabitance` rows in src/v3/spec/rust.dag lines
   169-207). Two paths surfaced: Option (i) wire BoundDeclaration into
   TargetIntegerInhabitanceBound; Option (ii) populate via existing
   variants if PlatformDependent already exists on the live carrier.
   Worker DFS at dispatch picks. Deliverable 3 retargeted to
   TargetIntegerTypeInhabitance rows (the actual surface).

* rust-primitive-full-coverage: codex inline confirms TargetIntegerInhabitanceBound has no PlatformDependent variant — Option (ii) infeasible; carrier refactor REQUIRED

Codex BLOCKING inline at PR #1910 line 65 (sha 98507c432) verified at
HEAD: TargetIntegerInhabitanceBound = BoundUnspecified | StaticBoundFact(IntInterval).
No PlatformDependent variant. Earlier brief framing of Option (ii)
(populate via existing variants) was infeasible.

Brief reframed: carrier refactor is required (not optional). Two
structural shapes for the refactor — (i.a) embed BoundDeclaration
(Mgr recommendation; single-authority discipline) vs (i.b) extend
variant set with PlatformDependent. Existing 5 rows migrate either
way; bootstrap snapshot semantic-equivalence non-negotiable.

* fix(briefs): retire INVARIANTS.md line-number cites in r3-426 brief

Per codex review on PR #1782 (sha c2512cde): the new briefs
introduced fresh `INVARIANTS.md:<line>` citations — the same
stale-line-anchor shape the :425 sweep brief itself names as needing
dissolution. Replaces four line-number references in
r3-426-sfp-subdoc-rename-and-author-worker.md (lines 16, 28, 58, 85)
with prose-anchored locators citing the section anchor + bullet text.

The other PB-lane briefs codex flagged (r3-pb-runtime-equivalence-
corpus-seed-audit.md, r3-pb-t-fixedpoint-worker.md) belong to
neat-bear-351's lane and are not in this PR's scope; will route
separately.

* fix(briefs): correct L6 type count + r3-435 dual-path retirement receipt

Per openai-pro review on PR #1782 (sha c2512cde):

1. L6 brief said acceptance ratchet asserts "five types" exist but
   declares six (ShapeATarget, FormAxis, BehaviorAxis,
   MethodTemplateContractKey, EmissionCell, EmissionPathProjection).
   Updated both occurrences to enumerate all six explicitly.

2. r3-435 brief authorized both Path A (typed-AST reader, deletes
   IntegrationRsScan) and Path B (scanner widening with Char state),
   but retirement receipt language only covered Path B. Updated
   ROADMAP/ledger retirement and authority-audit step 5 to cover
   both authorized dissolution paths.

* fix(briefs): L6 second 'five types' site + T-E-P lookup-gate authority

Per cursor review on PR #1782 (sha 2072b986):

1. L6 brief acceptance bullet at :131 still said "five types" while
   the parenthetical and the Slice step at :117 said six. The prior
   fix only caught one of two sites; corrected the second.

2. T-E-P brief `e_p_call_pattern_lookup_authoritative` acceptance
   named only `lower_call_pattern` as "the only route from call
   site to LoweringTarget" — but Phase 2 explicitly requires
   lenses route through `per_call_pattern_at` (the L-7 single-
   authority lookup), NOT `lower_call_pattern` (compiler-internal).
   Acceptance text rewritten to name `per_call_pattern_at` as the
   consumer-facing gate and clarify `lower_call_pattern`'s
   internal-only scope.

* fix(briefs): strengthen L6 ratchet from count-parity to per-row bijection

Per openai-pro REQUEST_CHANGES on PR #1782 (sha 2072b986): the L6
acceptance ratchet asserted only row-count parity between
emission_path_projections and the union of MethodTemplateContract
rows. Count parity permits duplicate projection keys and missing
source rows — the bridge from list-non-empty proxy to per-row
projection would not be mechanically proven. The whole point of
introducing MethodTemplateContractKey { target, dag_method } is to
provide 1:1 row identity.

Rewrites the ratchet to assert per-row bijection: every
MethodTemplateContract source row has exactly one matching
EmissionPathProjection row by key; every projection key resolves
to exactly one source row; duplicate projection keys fail closed.

(The other openai-pro BLOCKING finding — T-E-P
e_p_call_pattern_lookup_authoritative naming the wrong authority
— was already fixed at 6282a0704; the review citation was against
the pre-fix sha 2072b986.)

* fix(briefs): split L6 ratchet into slice-active vs deferred-activation gates

Per BLOCKING inline review on PR #1782 at d92459423: the prior
bijection ratchet was unsatisfiable as authored. The
*_method_template_contracts lists at HEAD (rust/python/go) are
non-empty; shipping emission_path_projections: [] alongside a
strict bijection requirement means the bijection cannot pass when
the slice lands — source rows would be uncovered. Prior text
incorrectly said "vacuously true on the empty source set" — the
SOURCE set isn't empty, only the projection set is.

Splits the ratchet into two gate categories:
- Slice-active gates: types/data shape exist + empty-state
  predicate (emission_path_projections == []).
- Deferred-activation gate: per-row key bijection, authored as a
  test scaffold by this slice but #[ignore]'d (or feature-gated
  on len > 0) until Grounding's follow-up populates rows. On
  activation, asserts the bijection over the populated set.

This honors P1 doc faithfulness: the slice's acceptance contract
is satisfiable as authored, and the bijection becomes the
load-bearing gate the row-population PR satisfies.

* fix(briefs): require L6 bootstrap enrollment to honor P2 facts-flow-forward

Per BLOCKING inline review on PR #1782 at L6:34: the slice authored
src/v3/std/cross_target_coverage.dag but never required enrolling
it in the bootstrap/load authority. Without enrollment the file
is dead-letter on disk and EmissionPathProjection can be absent
from the downstream Dag — silent P2 facts-flow-forward violation.

Adds a new Slice step 2 requiring a cross_target_coverage field
on BootstrapFixtures in src/v3/std/extdeps_bootstrap_fixtures.dag
mirroring the *_method_template_contracts enrollment pattern, plus
a loader-visibility ratchet. Renumbers subsequent Slice steps.
Adds matching Acceptance bullet.

* docs(briefs): normalize Practice 4 citation in S3 brief per codex review

Codex review on PR #1782 (sha 2614217e) flagged stale citation
"Practice 4 (Step 4 of the type-introduction checklist)" in
S3 brief — no such checklist step exists in the pinned rubric.

Live rule per docs/modeling-discipline.md:131-134 is the "What to
check" checkpoint-comment requirement under Practice 4 (coproduct
dissolution). Updated the S3 reference to cite that line directly
and drop the stale "Step 4 of type-introduction checklist" wording.

S2/S8/S9 already use bare "Practice 4" without the stale steps wording.
S1 (committed earlier today) does not contain the stale phrase.
S6 (pre-existing brief flagged by reviewer as carrying the same
pattern) is out of this branch's scope; flag for separate paydown.

* docs(briefs): sweep stale Practice 4 citations corpus-wide

Codex review on PR #1782 flagged the stale "Step 4 of the
type-introduction checklist" wording — no such checklist exists in
docs/modeling-discipline.md. The live rule is the "What to check"
checkpoint-comment requirement under Practice 4 (coproduct
dissolution) at docs/modeling-discipline.md:131.

Sweep across docs/ found 2 additional briefs carrying the stale
phrasing (S3 fixed previously at 9db003d40):

- docs/briefs/r3-l6-emission-path-projection-substrate-worker.md
- docs/briefs/r3-x1b-s1-transform-dispatch-substrate-worker.md

Both updated to cite the live rule directly. Verified zero
remaining "type-introduction checklist" or "Step 4 of the"
references in docs/ tree.

* docs(briefs): add Practice 4 citation discipline note to authoring checklist

Per parent inbox status flag at gunbc#828 #issuecomment-4385346221:
add a Citation discipline section to brief-authoring-checklist.md
naming the correct shape — Practice 4 (coproduct dissolution) +
"What to check" rule at docs/modeling-discipline.md:131 — and
calling out the stale "Step 4 of the type-introduction checklist"
phrasing as a failure mode. References the corpus sweep at
2dc92f34f.

Prevents future briefs that copy old templates from re-introducing
the stale citation pattern.

* docs(r3): cascade work post-Director ratification — S1 worker, R4 routing, Unit/Quantity canvas

Per Director ratification at gunbc#828 inbox response 2026-05-06
(zesty-bear-812):

1. S1 Q1+Q2 RATIFIED → author S1 gap-test representative worker brief
   (`r3-substrate-s1-gap-test-representative-worker.md`). Dispatchable
   on T-E-P Phase 1 + E6-G0d landing; closes ledger row #61.

2. S2 Q2 RATIFIED (option-(b) T-LBP narrowing) + S3 + S8 deferrals →
   R4 carve-out routing ledger (`docs/r4-carve-out-routing.md`).
   Captures C1 (parallelism lens), C2 (effect_enum lens), C3
   (register narrowing), C4 (deferred MachineConstraint axes),
   C5 (rounding-mode product extension), C6 (Unit/Quantity).
   Cascade messages to Verification / Grounding / Debt-Paydown Mgrs.

3. S9 Phase-3 dimensional refinement boundary → Unit/Quantity carrier
   canvas (`r3-substrate-s9-unit-quantity-carrier-canvas.md`).
   Surfaces Q-Unit-1..5 for Director ratification: carrier name,
   2-axis vs 3-axis Phase-1, Duration/Seconds collapse, Refined
   composition order, Practice 4 classification.

Updates §1.8 ledger receipts for carved items; R3 closure receipts
treat carved items as explicitly-deferred (not drift).

* docs(briefs): citation-discipline fix-forward — anchors/quotes, not line numbers

Director redirect at gunbc#828 #issuecomment-... noted the citation
paydown's replacement form (`docs/modeling-discipline.md:131`) is the
same drift class as the original fabricated-step error. Bare line
numbers shift silently on any doc edit above the cited line.

Generalized fix:
- brief-authoring-checklist.md "Citation discipline" section
  rewritten to prohibit bare line-numbers across ALL cross-doc
  references (modeling-discipline.md, r3-program-plan.md,
  r3-structure.md, INVARIANTS.md, MODELING.md, etc.). Use section
  anchors (#section-name) or rule-text quotes.
- 3 briefs that swapped in :131 (S3, S6, X1B) re-converted:
  - docs/modeling-discipline.md#4-coproduct-dissolution anchor
  - "What to check" rule quoted inline (self-contained)

Brief-authoring-checklist failure-mode section names both vectors
(fabricated step + bare line numbers) and references both sweep
commits in audit trail.

Broader cross-doc citation sweep across briefs I authored on this
branch (frontmatter authority-docs lists, body prose) is recommended
per Director note — flagging as separate paydown task; this commit
closes the immediate recurrence vector.

* docs(briefs): fix unfaithful Int=AbelianGroup<Nat> + sweep stale 'Step 4' refs

Per openai-pro review on PR #1782 sha 0ecd4818 (gunbc#1782 #...):

BLOCKING fix (P1 modeling faithfulness):
- S9 + S3 directed workers to model `Int = AbelianGroup<Nat>`,
  but Nat is not an Abelian-group carrier (additive inverses
  not representable). Reframed:
  - `Int` is the additive Abelian group on integers (carrier Z);
    `Nat` is a commutative monoid under addition.
  - Algebraic relationship is **explicit group-completion**:
    `Int ≡ GroupCompletion<CommutativeMonoid<Nat>>` — NOT
    `AbelianGroup<Nat>` parameterization.
  - Worker either models `Int` directly as `AbelianGroup`
    (terminal Abelian-group instance) OR introduces explicit
    `GroupCompletion<M>` substrate carrier; decision lands in
    Phase-1 PR per P1 procedure.
- S3 cross-reference + Phase-4 algebra-axis preservation note
  reframed accordingly.

NON-BLOCKING in-PR cleanup (Practice 4 citation discipline):
- 6 briefs still carrying stale 'Practice 4 Step 4' wording
  (r3-coproduct-1/2/3, r3-l6, r3-t-e-p, r3-x1b) updated to use
  the section anchor (`docs/modeling-discipline.md#4-coproduct-dissolution`)
  + inline rule-text quote ("What to check") form per the
  citation discipline established in `b4cae5299`.

Closes both findings from openai-pro review.

* docs(briefs): Q-Unit-1..5 RATIFIED — apply Scale.Unit→One rename + ratification banner

Director ratified Q-Unit-1..5 at gunbc#828 #issuecomment-... 2026-05-06
(zesty-bear-812). All 5 questions ratified; one rename required:

- Scale enum's `Unit` value collides with outer `Unit<Q, S>` carrier
  name (`Unit<Time, Unit>` is shadowing-confusing). Rename to `One`.
- Duration ≡ Unit<Time, One> (collapses with Seconds per Q-Unit-3).
- Milliseconds ≡ Unit<Time, Milli>.

Canvas updated:
- Top-level RATIFICATION banner records all 5 ratifications + rename
- Scale enum: `Unit` → `One` (with inline rename receipt)
- Sketch product expansions use `Unit<Time, One>` / `Unit<Time, Milli>`
- Phase-3 reframe table products updated
- Q-Unit-3 prose collapse reference updated

Subsequent worker brief authoring (Unit/Quantity carrier landing
post-prerequisite) inherits the renamed shape.

* docs(briefs): Unit/Quantity carrier worker brief — Q-Unit-1..5 RATIFIED

Worker brief consumes the ratified Unit/Quantity canvas
(`5f22fd06e` ratification banner). Phase-1 lands `Unit<Q, S>` +
`Quantity` + `Scale` declarations at the ratified shape (Scale's
`One` value per Q-Unit-1 rename). Phase-2 reframes S9 Phase-3
dimensional refinements (Duration / Seconds / Milliseconds) to
outer-Refined / inner-Unit composition per Q-Unit-4 RATIFIED.
EpochMs deferred to R4 C6 (Aspect-axis follow-up).

Practice 4 marks pre-determined per Q-Unit-5: `Unit<Q, S>` 🟢
PRIMITIVE; `Quantity` + `Scale` 🟡 SCAFFOLD with "consumed by ≥1
emission rule" dissolution trigger.

Cross-program handoff to Grounding Mgr (#1745) for dimensional
emission consumption documented.

Worker pin TBD — dispatchable when idle pool refreshes.

* docs(briefs): S9 Phase-1 reframed — Int landed at #1466; UInt-only migration

Per proud-lynx-311 dispatch ack at gunbc#1739 #issuecomment-...
2026-05-06: re-grep at HEAD revealed substrate state diverges
materially from S9 brief's "Option A vs B decide" framing.

Reality check at HEAD:
- `dsl/std/integer.dag:55` already carries
  `type Int = AbelianGroup<GroupCompletion<Nat>>` per Slice 3 PR
  #1466 / commit `4ba0a6d04`. Single-authority Q6 audit doc at
  `docs/audit/t-numeric-construction-group-completion-6q.md`
  ratified this shape and explicitly rejected the compact form.
- `dsl/std/integer.dag:56` still on legacy `type UInt = UInt64`
  alias; UInt migration is the actual Phase-1 worker scope.

Brief Phase-1 step 1 reframed: Int landing acknowledged; worker
confirms HEAD match. Phase-1 step 2 reframed: UInt migration
target named (`type UInt = CommutativeMonoid<Nat>`); fixed-width
rows preserved per existing legacy-rows policy.

Historical Option A vs B framing kept as note (superseded).

Confirmed S9 dispatch ack from worker; UInt-only Phase-1 PR is
in-scope. Emission entries deferred per S3 (valiant-ant-72
pre-landing); Phase-2 deferred per S8 (quiet-boar-160 pre-landing).

* docs(briefs): fix two BLOCKING citation drift items per codex review

Codex review on PR #1782 sha 5f22fd06 flagged two authority-receipt
gaps:

1. brief-authoring-checklist.md:118 — `<this-commit>` placeholder in
   the failure-mode section was unverifiable post-merge. Replaced
   with `b4cae5299` (the actual anchor/quote conversion commit).

2. r3-378-http-path-helper-fail-open-worker.md:84 — `INVARIANTS.md
   C-8 fail-closed` cited without anchor or rule-text quote, in
   violation of the citation discipline added in this PR.
   Converted to `INVARIANTS.md#p3-fail-closed` (P3 heading anchor)
   + inline rule-text quote naming P3 + C-8.

PR's own discipline now consistently applied across the diff.

* docs(briefs): sweep bare .md:NNN citations in Substrate-Mgr-authored briefs

Per Director recommendation in citation-discipline thread (gunbc#828
follow-on): bare line-number references drift silently. Swept 19
remaining instances across 5 briefs I authored on this branch:

- docs/briefs/r3-substrate-s1-q-class-2-chain-break-gap-test-canvas.md
- docs/briefs/r3-substrate-s1-gap-test-representative-worker.md
- docs/briefs/r3-substrate-s2-t-lbp-scope-calibration-canvas.md
- docs/briefs/r3-substrate-s3-machine-constraint-carrier-worker.md

Conversion: bare `file.md:NNN` → `file.md §"Section name"` form.
Stable; survives doc edits; human-readable. Section names per
HEAD heading audit.

Verification: `grep -nE '.md:[0-9]+' docs/briefs/r3-substrate-*.md
docs/r4-carve-out-routing.md` returns zero results in
Substrate-Mgr-authored scope.

Broader corpus scope (~232 references across non-Substrate briefs)
remains as separate paydown task.

* docs(briefs): fix BLOCKING + NON-BLOCKING items per openai-pro review on a462f007

Three findings addressed; 2 BLOCKING + 1 NON-BLOCKING:

BLOCKING — R3/R4 dual authority for Unit/Quantity carrier:
R4 carve-out C6 narrowed from "Unit/Quantity carrier landing"
(deferred all of it) to **"Aspect-axis (PointKind) follow-on
for EpochMs and instant/rate-shaped refinements only"**. The
2-axis Measure<Q,S> carrier landing IS in R3 per Q-Unit-1..5
RATIFIED; only the Aspect axis (PointKind = Magnitude | Instant
| Rate) carves to R4. Cascade-message C6 reference + R4 program-
plan input list updated to match. Cross-Mgr message clarifies
Grounding consumes 2-axis dimensional refinements in R3.

BLOCKING — Locked design partially applied (Scale.Unit→One
rename in canvas alternate-sketch sections):
- Canvas line 105-108 alternate sketch ("Open question: Instant
  vs Duration axis") still used pre-rename `Unit` Scale value;
  added pre-ratification disclaimer marking the section as
  deferred to R4 C6 + noting `Unit` is pre-rename
- Canvas line 163 Q-Unit-3 collapse note: `Scale = Unit` → `Scale = One`

(BLOCKING — bare line-numbers in S1 canvas frontmatter): NOT
APPLICABLE — already fixed at sweep commit 127287a66 prior to
review; reviewer was on sha a462f007 pre-sweep.

NON-BLOCKING — placeholder receipts:
- brief-authoring-checklist.md `#issuecomment-...` → concrete ID
  4385393971 (Director's anchor-discipline reply)
- r3-substrate-unit-quantity-carrier-worker.md (3 occurrences)
  + canvas RATIFICATION banner: `#issuecomment-...` → concrete ID
  4385412256 (Q-Unit ratification reply)
- `<this-commit>` placeholder in checklist already fixed at 5be1c99f2

Verification: zero `#issuecomment-...` or `<this-commit>` placeholders
in docs/briefs/ + docs/r4-carve-out-routing.md.

* docs(briefs): codex BLOCKING review fixes — Practice 4 source-level + policy scope

Three BLOCKING findings on PR #1782 (codex sha b913e2f4):

1. **Citation-discipline policy scope**: addressed by scoping
   the rule prospectively to briefs landing after the policy
   commit (`b4cae5299`). Pre-existing corpus references are
   flagged as paydown but NOT individually blocking; coordinated
   single-PR sweep is the right paydown shape. Substrate-Mgr scope
   already swept at `127287a66`.

2. **R4 C6 reconciliation**: already fixed at `6e5a5481a` (R4 C6
   narrowed to Aspect-axis follow-on for EpochMs only; 2-axis
   carrier landing IS in R3). Codex sha b913e2f4 was pre-fix.

3. **Practice 4 source-level vs PR-body conflation**: corrected.
   Acceptance bullet for Unit/Quantity worker brief now requires
   inline checkpoint comments on the LIVE declarations in
   `dsl/std/units.dag` (load-bearing artifact per
   `docs/modeling-discipline.md#4-coproduct-dissolution` "What to
   check"). PR-body summary is supplementary, not substitute.

Closes the review's reconciliation gates.

* docs(briefs): absorb Q-MachineConstraint + Q-Unit-1-Recanvas ratifications

Two major Director ratifications absorbed:

1. Q-MachineConstraint-Carrier RATIFIED at gunbc#828
   #issuecomment-4385530115 (Brian directive 2026-05-06: "universal
   substrate, ratify defaults"; PR #1817 queued). 6 sub-decisions:
   - MachineWidth<bits> only for R3; defer RegisterClass / EndianMode
     / Alignment / signedness post-R3
   - Parametric Compose<Algebra, MachineConstraint> type-level
     interaction shape (lookup-maps REJECTED — AlgebraMachineProduct
     record-keyed table form retracted)
   - Int<64> ≡ Compose<AbelianGroup, MachineWidth<64>> (algebra-side
     options A and B preserve interaction semantics)
   - Real<64> ≡ Compose<ApproximateField<Rational>, MachineWidth<64>>
     (algebra approx + machine approx as independent composing axes)
   - ≥3 pairs is minimum, not target
   - UNIVERSAL substrate: every target carries machine-constraint
     facts; targets without native machine-width semantics handle
     omission at Grounding-level discharge (target-conditioned
     lowering NOT target-conditioned substrate)

   Reframed: S3 brief Phase-1, S3 Phase-3/4 emission entries,
   S8 Phase-1/2/3 (ApproximateField<Real> → ApproximateField<Rational>;
   AlgebraMachineProduct → Compose<...>), S9 emission entries.

2. Q-Unit-1-Recanvas RATIFIED Measure<Q, S> at gunbc#828
   #issuecomment-4385539791. valiant-ibex-312's substrate-state
   grep caught Unit<Q, S> collision with kernel Unit at
   dsl/std/types.dag:176; Director ratified Measure<Q, S> as
   outer carrier name (conventional in scientific computing;
   no dsl/std/ collision).

   Reframed: Unit/Quantity worker brief throughout (Unit<Q,S> →
   Measure<Q,S>; dsl/std/units.dag → dsl/std/measure.dag); canvas
   spec sections + sketch products (Refined<Measure<Time, ...>...>);
   R4 carve-out C6 with informal/formal name disambiguation note.

Both rename + reshape are now consistent across S3 / S8 / S9 /
Unit-Q briefs + canvas + R4 routing. Workers (valiant-ant-72 on S3,
quiet-boar-160 on S8, proud-lynx-311 on S9, valiant-ibex-312 on
Unit-Q) all dispatch against the ratified shape.

* docs(briefs): S11 Slice C worker brief — ROADMAP :425 retirement post-#1801

Cascade-clearance trigger fired post-#1801 (Slice B) merge
2026-05-06. S11 brief authored per B1 RATIFIED prose+regen
bundling discipline.

Phase 1: per-file edits across the post-A+B residual list (~10
files per smart-ram-167's Slice B post-rebase enumeration);
anchor + rule-text-quote pattern per current citation discipline;
bootstrap regen in same PR (no split).

Phase 2: ROADMAP :425 row PARTIAL → Retired with 3-slice receipt;
Q-Slice-C-Retirement-Receipt resolution.

Worker pin smart-ram-167 (#1759) — Slice B precedent owner.
Dispatch packet sent separately to #1759.

* docs(briefs): Q-Refined-Phantom-Composition (c) RATIFIED — defer literal Refined form

Director ratified option (c) at gunbc#828 #issuecomment-... 2026-05-06:
drop `non_negative` predicate at Measure (phantom) layer; rely on
`Quantity = Time` tagging for non-negative-magnitude semantics.

Q-Unit-4 outer-Refined / inner-Measure composition is preserved as
**conceptual model**; the literal `Refined<Measure<...>, predicate>`
form is **deferred to value-typed-integration follow-up** when
substrate gains Refined<> as first-class type expression and
dimensional refinements get value-typed integration.

Updates:
- Canvas RATIFICATION banner Q-Unit-4 row reframed to "conceptual
  model; literal form deferred"
- Canvas Phase-3 reframe table: Duration / Milliseconds drop the
  Refined<...> wrapper; rely on Quantity tag
- Worker brief Phase-2 prose + reframe table + Acceptance bullet
  all reflect deferred-literal-form posture

valiant-ibex-312 unblocked to proceed with Phase-2 (Grounding
handoff doc) per the (c)-shaped Acceptance.

* docs(briefs): S12 F2 + F8 doc-sharpening worker brief — post-#1820 cascade

#1820 (Slice C) merged 2026-05-06; ROADMAP :425 row Retired closes
the prose-reference paydown program. S12 cascade-clearance trigger
fires per B6 RATIFIED single bundled Mgr-tier doc-sharpening PR.

Scope: F2 (.v3 filename-suffix grammar dispatch) + F8 (bootstrap
load-order/exclusion authority) — single bundled PR per B6.
Cross-program coordination with PB Mgr (#1742) per design schedule
§3 P5 (comment-only OR co-author; no duplicate PR).

Worker pin smart-ram-167 (#1759) — Slice C precedent owner;
pattern-familiar with prose+regen bundling discipline. Dispatch
packet sent separately to #1759.

* docs(briefs): S9 brief — UInt landed via #1818; algebra label corrected to CommutativeSemiring

Per proud-lynx-311 merge report at gunbc#1746 #issuecomment-...
2026-05-06: PR #1818 landed `type UInt = Nat` after codex BLOCKING
review on initial `CommutativeMonoid<Nat>` form (P2 facts-flow-forward
violation — wrap projects out Nat's multiplicative monoid + identity 1).

Final landed form preserves full `CommutativeSemiring<Magnitude>`
surface — Nat IS a commutative semiring (addition + multiplication
+ 0 + 1). Algebra-side label for UInt is CommutativeSemiring, NOT
CommutativeMonoid (corrects my earlier dispatch labeling).

S9 Phase-1 step 2 marked LANDED with merge ref. Phase-1 step 3
emission entries reframed:
- Int<N> ≡ Compose<AbelianGroup, MachineWidth<N>>
- UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>>

Worker discipline + reviewer caught a substrate-state error in my
brief framing; brief now matches landed reality.

* docs(briefs): fix contradictory (c) guidance in Unit/Quantity worker brief

Codex BLOCKING review on PR #1825 sha 1bce0418 caught a real
contradiction: brief Phase-2 prose at lines 115-118 stated
"predicates do NOT attach at the Measure (phantom) layer" per
Q-Refined-Phantom-Composition (c) RATIFIED, but immediately
following paragraph at lines 130-132 still said "Refined predicate
non_negative applies at the Measure-typed level" — left over from
the original Q-Unit-4 framing.

Updated lines 130-137 to consistently apply (c) shape: predicates
deferred to value-typed-integration follow-up; dimensional semantics
ride on Quantity tag at Measure layer; worker authors 3 in-scope
refinements WITHOUT predicate at this layer.

P2 boundary discipline restored: brief now gives single-authority
guidance for Phase-2 substrate landing.

* docs(briefs): name predicate authority + concretize ratification ID — codex BLOCKING

Codex BLOCKING review on PR #1825 sha 32541a56:

1. (BLOCKING) Q-Refined-Phantom-Composition (c) ratification deferred
   phantom-carrier predicates without naming the value-level predicate
   authority. Updated canvas Q-Unit-4 RATIFICATION row to explicitly
   name: 'predicates re-attach at value-typed Int/UInt level via
   where-sugar (e.g., range(min: 0) per current dsl/std/types.dag
   precedent)' when value-typed integration lands.

2. (BLOCKING) Worker brief option-c reframe didn't sweep the audit
   receipt §5 (Carrier dissolves the bridge). Updated to consistently
   apply (c) shape — dimensional semantics ride on Quantity tag at
   Measure layer; value-level predicate authority deferred; until
   then, range/gt_zero constraints attach at value-typed Int/UInt
   via where-sugar per dsl/std/types.dag convention.

3. (NON-BLOCKING) Canvas had #issuecomment-... placeholder for the
   (c) ratification message ID. Replaced with concrete
   #issuecomment-4385687075 per dashboard relay header.

Brief now names a single value-level authority (Int/UInt where-sugar)
for value-range facts; phantom-layer Quantity tag carries only
dimensional semantics. P2 boundary discipline maintained.

* docs(briefs): S12 RETIRED per Director option (2) ratification

Director ratified option (2) at gunbc#828 #issuecomment-4385873...
2026-05-06 post smart-ram-167's substrate-state STOP-AND-ESCALATE:

- F2 absorbed by 2026-05-04 routing + #1662 closure
  (`Result/DivError span.file-keyed` retired)
- F8 topical concerns distributed across live rows
  (Class 5 Gap 3 `bootstrap.rs::std_fixtures()`; Character-level
  load-set / bootstrap; Filename-sentinel-bridges) with own owners
- Doc-discipline goals absorbed by per-Mgr citation paydown
  routing at gunbc#828 #issuecomment-4385583247

Frontmatter updated to RETIRED with absorption receipt. Worker
(smart-ram-167) pin freed.

Director-side acknowledgment of Substrate Mgr's option (2) recommendation:
"Substrate Mgr's option (2) recommendation is the right move
structurally. Most Mgrs default to 'synthesize work to fill the brief'
when canvas-vs-HEAD mismatch surfaces. Recommending retirement when
the work is genuinely absorbed is harder discipline."

* docs(briefs): S7 PR-F (BoundDeclaration consumer + ReferenceModel<T>) worker brief

Per cascade-clearance trigger fired post-#1782 merge 2026-05-06.
loyal-wolf-828 (#1764) acknowledged S7 dispatch with substrate-state
pre-flight grep (gunbc#1764 #issuecomment-4385872...) and surfaced
await-brief posture. This brief satisfies that prerequisite.

Worker pre-flight inventory absorbed:
- BoundDeclaration substrate landed (substrate.dag StaticBound +
  PlatformDependent); partial BoundDeclarationView consumer in
  fold.rs (ScratchIntExamples scope; doc-explicit partial)
- ReferenceModel<T> NOT yet in dsl/std/ (substrate-fact-introduction
  required; design-emission-model.md §Q2 framing)

Phase-1: BoundDeclaration consumer broadening to full
design-emission-model.md surface (u128 / isize / usize / walker
arms / pilot mirror).

Phase-2: ReferenceModel<T> P1 substrate-fact-introduction with
DFS-of-concept-DAG + Practice 4 in-source checkpoint comment +
named consumer demand (Grounding G1).

Phase-3: cross-program handoff to Grounding Mgr (#1745) for
G1 (T-Ground-Rust Phase 1).

Closure predicate: unblocks Grounding T-Ground-Rust Phase 1.
Worker pin loyal-wolf-828 holds; dispatch fires immediately
on this brief landing.

* docs(briefs): S9 Slice 2.5 — predicate-registry + PB-1 shim retirement (Path 3 RATIFIED)

Director ratified Path 3 at gunbc#828 #issuecomment-4390333451
post proud-lynx-311's pre-flight DFS at gunbc#1746 #issuecomment-4390253616.

Brief reframes Slice 2.5 from S-sized (primitive + 1 consumer) to
L-sized (predicate registry + PB-1 shim retirement). 5 deliverables:
1. gt_zero primitive predicate
2. Predicate registry infrastructure (resolver-side substrate-fact-introduction)
3. PB-1 shim retirement (span.file=='dsl/std/types.dag' special case dissolves)
4. Migration of existing types.dag predicates (range, pattern, etc.)
5. PositiveInt = Refined<Nat, gt_zero> consumer update

Per Director hard scope bars: no parallel predicate-resolution path;
no per-call-site special-casing; PB-1 shim retirement non-negotiable
in same slice. Single PR per Path 3 RATIFIED.

Discipline anchors: feedback_construction_over_ratchets (PB-1 shim
is bridge); feedback_dissolve_bridges (registry is structural fix);
feedback_no_textual_enforcement_bridges (file-path special-case is
anti-pattern shape); P1 substrate-fact-introduction procedure.

Worker pin proud-lynx-311 — Director pre-cleared on pre-flight DFS
context. PR #1840 (partial Slice 2 — NonNegativeInt = Nat) MERGED
at 16:54Z; Slice 2.5 dispatchable immediately on this brief landing.

* docs(briefs): Slice 2.5 audit receipt — Mgr independent grep parallel-verifies worker DFS

Codex BLOCKING review on PR #1845 sha 2d230949 flagged: external PR
receipt absorbed as live substrate state without re-grepping local
std declarations at brief authoring time. Authority receipt §1
cited proud-lynx-311's pre-flight DFS as authority but didn't
record Mgr-side independent verification.

Updated audit receipt §1 + §4 to record Mgr's independent grep at
HEAD as parallel verification:
- gt_zero zero matches in dsl/std/ + src/v3/ (verified)
- NonNegativeInt = Nat at dsl/std/integer.dag:133 (#1840 land)
- PositiveInt = Int where range(min: 1) at dsl/std/types.dag:255
- PB-1 shim doc-block confirms bridge-text framing
- Predicate registry confirmed not present

Worker DFS remains the dispatch-time discipline (substrate-state
grep at dispatch); Mgr's independent grep is parallel verification,
not substitute. Per Director's pattern note at gunbc#828
#issuecomment-4390199218 + #issuecomment-4390333451: dispatch-packet
authoring discipline includes Mgr-side substrate-state-grep, not
just relay of worker findings.

* docs(briefs): Slice 2.5 brief — Int extensibility scope-bound; lower.rs cites anchored

openai-pro REQUEST_CHANGES on PR #1845 sha 2d230949 flagged 2 issues:

BLOCKING — P1 modeling faithfulness / substrate scope leak:
`gt_zero` Int-side extensibility was left to 'worker judgment if
generalization cheap'. Per feedback_construction_over_ratchets:
don't speculatively extend predicate-carrier compatibility ahead
of named consumer demand. Reframed to **EXPLICITLY OUT-OF-SCOPE**
for Slice 2.5; Nat-only registration. Future Int-side consumer
surfaces as separate substrate-fact-introduction (P1 procedure)
brief with own consumer-demand receipt.

NON-BLOCKING — citation discipline self-violation:
3 instances of bare `lower.rs:821-835` line-range citations
contradict the brief's own 'no bare :NNN' requirement at line 211.
Converted to function-name anchored form:
`src/v3/compiler/src/lower.rs` (`lower_type_alias_refinements_phase` doc-block).

Both findings absorbed; no parallel scope ambiguity remains;
brief now self-consistent on citation discipline.

* WIP: R3 Substrate

* docs(briefs): Slice 2.5 brief — audit-receipt cites converted to declaration-name anchors

cursor APPROVE_WITH_COMMENTS on PR #1845 sha ebf6ac12 noted citation
self-inconsistency: audit-receipt section §1 + §4 used bare
`dsl/std/integer.dag:133` and `dsl/std/types.dag:255` line-number
pins despite the brief's own no-bare-:NNN rule.

Converted to declaration-name-anchored form:
- 'declaration named NonNegativeInt' (with reproducible grep command)
- 'declaration named PositiveInt' (with reproducible grep command)
- 'lower_type_alias_refinements_phase doc-block' for PB-1 location

Brief now fully self-consistent on its own citation discipline.
Verified zero remaining .dag:NNN / .rs:NNN / .md:NNN bare cites.

* docs(briefs): Slice 2.5 brief — Path (a) RATIFIED carrier+argument contract verification

Director Path (a) RATIFIED at gunbc#828 #issuecomment-4390760353
(triage) + #issuecomment-4390794121 (convergence ack):
predicate-body lowering with carrier+argument contract
verification at lower-time IN SAME SLICE. Placeholder semantics
REMOVED from registry path.

Codex REQUEST_CHANGES surfaced that registered-predicate-without-
contract = silent acceptance per feedback_fail_closed_discipline.
Brief reframe absorbs Path (a):

Hard scope bar #5 added:
- Same-slice carrier+argument-contract verification
- Mismatched carrier OR malformed argument → Diagnostic::ResolveError
- No 'named but not checked' path remains

Scope expansion section added (L → XL):
- Predicate-body lowering for all 7 registered predicates
- Per-predicate arg-shape validation
- Multi-session work acknowledged
- Carrier-check at 788d6acb4 retained; predicate-body builds on top

Acceptance bullets updated: gt_zero with arg-shape validation +
all 7 predicates with carrier+argument contract verification.

Director-pinned brief-authoring discipline: dissolution trigger
named in a brief authored as substrate-fact-introduction must
specify same-slice acceptance, not deferred follow-up. Otherwise
the brief encodes 'land bridge + defer dissolution' anti-pattern,
the same shape feedback_construction_over_ratchets warns against
at implementation layer applied at brief authoring layer.

This is the 11th miss this session — but the pattern surfacing it
(direct sweep + Codex REQUEST_CHANGES + Director ratification)
produces structural fixes that prevent the next miss class. Brief
revision is the structural recovery.

* docs(briefs): Slice 2.5 brief — Path 2 RATIFIED (Gap 1 discharge + Q-Regex carve-out)

Director Path 2 RATIFIED at gunbc#828 #issuecomment-4391985613
post Rung 3 STOP at gunbc#1746 #issuecomment-4391946213.

Path 2 narrowing of Path (a):
- gt_zero + range body synthesis already landed (5f3c40c3a)
- Gap 1 discharge mechanism: extends scalar-literal predicate
  evaluation at lower-time. L-class; lands SAME SLICE per
  same-slice-dissolution discipline
- non_empty + brand body synthesis: lands via Gap 1 discharge
- pattern / format / content: fail-closed-with-named-dep at
  user-code authoring layer (Diagnostic::ResolveError naming
  Q-Regex-Primitive). NOT placeholder; structural rejection
- PB-1 shim FULLY RETIRED per hard scope bar #3
- Q-Regex-Primitive carved as follow-on substrate-fact-introduction
  (XL substrate; not pre-authored per feedback_construction_over_ratchets)

Acceptance updated:
- 4 of 7 body-synthesized in same slice
- 3 of 7 fail-closed-with-named-dep (no placeholder semantics)
- Gap 1 discharge mechanism landed (no partial implementation)

Worker disposition: proud-lynx-311 continues Rung 3 with Gap 1
implementation + non_empty/brand body synthesis + pattern/format/
content fail-closed-with-named-dep diagnostic.

* docs(briefs): S9 Phase-1 Step 3 emission entries — Tier-1 brief authoring (1/5)

First Tier-1 brief landing post Director auto-nudge on assignment
#1858. Authored against Q-MachineConstraint sub-decisions ratified
shape now landed at #1856:

- Int<N> ≡ Compose<AbelianGroup, MachineWidth<N>> → Rust i32/i64/i128
- UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>> → Rust u32/u64/u128
- 6 concrete instantiations (≥3 minimum per sub-decision 5)
- Cross-program handoff to Grounding Mgr (#1745) for G2 emission consumption
- numeric_construction_demonstration Acceptance bullet (Int<32> round-trip);
  Real<64> half deferred to S9 Phase 2 / S8 Float cascade

Brief authored with substrate-state-grep discipline + same-slice-
dissolution discipline (no deferred trigger; demonstration in same
slice or explicitly carved). 5-question authority audit completed
in brief body.

Worker pin proud-lynx-311 (S9 holds); brief queues post-Slice-2.5
completion as natural follow-on.

Tier-1 brief queue progress:
- 1/5 authored (this brief)
- 4 remaining: S9 Phase-2 Float coordination; T-LBP complexity
  cementing; T-LBP cost cementing; S3 Phase-2 parser-grammar

* docs(briefs): S3 Phase-2 parser-grammar surface — Tier-1 brief 2/5

Authored per Director freed-pool pressure at gunbc#828
#issuecomment-4392095857 + Tier-1 brief-queue commitment.

Brief covers parser-grammar surface for Compose<Algebra, MachineConstraint>
interaction syntax post-#1856 (Phase-1 carrier slice landed):

- Phase 2.1: Parser surface per ratified Q-MachineConstraint-Grammar-Shape
- Phase 2.2: Bootstrap demonstrator with >=3 algebra*machine-axis pairs
- Phase 2.3: Class 1 5-criteria Pass receipt (criteria 1-4; criterion 5
  v2-oracle parity may carve)
- Phase 2.4: numeric_construction_demonstration co-receipt with S9 Phase-1
  Step 3 emission entries brief

Director ratification HOLDS on grammar bikeshed:
- Candidate A: Int @ Width<32> (annotation form)
- Candidate B: Int with MachineWidth<32> (with-form)
- Candidate C: Int<32> (positional generic — fits existing convention)
- Candidate D: Compose<AbelianGroup, MachineWidth<32>> (no parser change;
  type aliases provide convenience names)

Worker pin valiant-ant-72 holds (S3 Phase-1 precedent owner); freed-pool
until Director ratifies grammar shape.

Tier-1 brief queue progress: 2/5 authored (this brief + S9 Phase-1 Step 3).
Remaining: S9 Phase-2 Float coordination; T-LBP complexity cementing;
T-LBP cost cementing.

* docs(briefs): S3 Phase-2 brief — fix internal contradiction on Class 1 closure scope

Codex BLOCKING review on PR #1889 sha ec609b4a flagged real
contradiction:

- Provenance section claimed '5-criteria Pass closed' (line 229)
- Phase 2.3 said 'criterion 5 may queue separately' (line 154)
- STOP-AND-ESCALATE bullet 1 ratified 4-of-5 carve-out (line 181)

Updated Provenance to consistently state criteria 1-4 close in this
slice; criterion 5 (v2-oracle parity) cementing test may carve to
separate slice. Single 4-of-5 framing throughout. INVARIANTS.md
'Documentation Describes Live State' satisfied.

Per feedback_construction_over_ratchets: don't claim closure that
isn't structurally complete. 4-of-5 + named carve is the honest
shape; 5/5 only on cementing-test land.

- 4 predicates body-synthesize via Gap 1 (gt_zero / range / non_empty
  / brand)
- pattern / format / content STRUCTURALLY ABSENT from registry (not
  pending-with-placeholder); user-code where-clause produces
  Diagnostic::ResolveError naming Q-Regex-Primitive as separate

- ~12 types.dag refined-type declarations migrate to drop
  pattern/format/content where-clauses with inline-comment receipts

  adapts as needed
- PB-1 shim FULLY RETIRED — no exception, no preserved branch
- Q-Regex-Primitive as separate brief / worker pin / Director

  REJECTED)

Phase ordering rewritten to absorb migration as explicit phase
between predicate enrollment and shim retirement. proud-lynx-311

Substrate Mgr canvas authored post-codex BLOCKING + PM disposition
handoff at gunbc#846 #issuecomment-4392510255.

Two real substrate-shape questions stacked:

Q1 (category mismatch): Lens<C>.read is per-Behavior; emission
provenance is per-emitted-line. 4 options surfaced — (a) per-Behavior
Lens-compatible / (b) per-line instrumentation NOT a lens / (c)
withdraw + re-canvas / (d) Mgr-surface both substrates distinct.
Mgr recommends (d) if visualization is load-bearing; (a) suffices
if per-Behavior aggregate works for the slide. Brian-channel
sub-question surfaced.

Q2 (fold-rule enumerability): T-Rule-Enumeration substrate-fact-
introduction is prerequisite for every Q1 path (rust_target.rs uses
inline &str template names; rules not enumerable). Mgr recommends
parallel-dispatch with Q1 deliberation — satisfies Brian's ASAP
framing while shape ratifies.

Q3 (§1.8 ledger retarget): #89 already taken by T-LAS; new cluster
location follows Q1 disposition.

Director ratification ask + Brian-channel sub-question surfaced.

per Q-MC sub-decision 3 critical correction at gunbc#828
#issuecomment-4385530115:

  "prior phrasing Compose<AbelianGroup, MachineWidth<64>> was wrong
  — AbelianGroup<T> is a witness shape over carrier T, not a carrier
  constructor; bare AbelianGroup in slot-1 composes witness rather
  than concept."

Slot-1 is the fully-applied algebraic-concept name:
- Int<N>  = Compose<Int,  MachineWidth<N>>   (Int = AbelianGroup<GroupCompletion<Nat>>)
- UInt<N> = Compose<UInt, MachineWidth<N>>   (UInt = CommutativeSemiring<Nat>)
- Real<N> = Compose<Real, MachineWidth<N>>   (Real = ApproximateField<Rational>)

Phase-2 Float brief also retargets user-facing surface from Float<N>

Real is the algebraic-concept name per Q-MC sub-decision 3 example).

* WIP: R3 Substrate

* briefs: address codex BLOCKING bundle (sha 2ed1046e) — record-form provenance + emit_model carrier alignment + T-Rule-Enumeration retirement flag

Three findings addressed:

1. Lens brief (Finding #1 — provenance shape conflates source vs rule
   attribution): replaced typed-sum EmissionOrigin with record
   EmissionProvenance { rule: EmissionRule [mandatory], source_span:
   Option<SourceSpan> [optional] }. Co-inhabitance is real (e.g.,
   #[derive(Debug)] line has both rule=derive_for_disj AND span
   attribution to Foo decl). Rule-mandatory enforces fail-closed
   structurally; Practice 4 N/A (record, not coproduct).

2. T-Rule-Enumeration brief (Finding #2 — rule authority lives in
   spec/rust.dag + v3.std.emit_model, not call-site strings): brief
   status flipped to FLAGGED FOR RETIREMENT. Same finding as
   smart-ram-167 STOP at gunbc#1759 #issuecomment-4392696623; Reading
   C surfaced to Director at gunbc#828 #issuecomment-4392780871.

3. Rust-primitive-full-coverage brief (Finding #3 — BoundDeclaration
   not wired into TargetIntegerInhabitanceBound row surface):
   reframed Deliverable 2 to target the actual carrier
   `v3.std.emit_model::TargetIntegerInhabitanceBound` (used by
   `TargetIntegerTypeInhabitance` rows in src/v3/spec/rust.dag lines
   169-207). Two paths surfaced: Option (i) wire BoundDeclaration into
   TargetIntegerInhabitanceBound; Option (ii) populate via existing
   variants if PlatformDependent already exists on the live carrier.
   Worker DFS at dispatch picks. Deliverable 3 retargeted to
   TargetIntegerTypeInhabitance rows (the actual surface).

Codex BLOCKING inline at PR #1910 line 65 (sha 98507c432) verified at
HEAD: TargetIntegerInhabitanceBound = BoundUnspecified | StaticBoundFact(IntInterval).
No PlatformDependent variant. Earlier brief framing of Option (ii)
(populate via existing variants) was infeasible.

Brief reframed: carrier refactor is required (not optional). Two
structural shapes for the refactor — (i.a) embed BoundDeclaration
(Mgr recommendation; single-authority discipline) vs (i.b) extend
variant set with PlatformDependent. Existing 5 rows migrate either
way; bootstrap snapshot semantic-equivalence non-negotiable.

* emission-provenance lens brief: absorb codex BLOCKING bundle (sha 4229cd09 post-merge findings)

Two findings from codex bundled review on now-merged PR #1910 sha
4229cd09 land as brief revisions for the in-flight smart-ram-167
authoring cycle (PR #1928):

1. Field-path identity threading: render_named_template call sites
   receive template values extracted from binding structs; field-path
   may not be carried alongside the value at emission time. New STOP
   trigger flags this as substrate-cascade if threading isn't
   structurally possible (typed template-with-rule-path or
   DeclarationRef carrier needed).

2. Read domain coverage gap: Lens<C>.read is per-Behavior; emitted
   output also includes declarations + program scaffold. Acceptance
   scope explicitly narrowed to Behavior-attributable lines only;
   declarations + scaffold provenance out-of-scope (separate substrate
   cascade if surfaced). Acceptance bullet retargeted to
   "Behavior-attributable span-Some + Behavior-attributable span-None"
   rather than full-emission coverage.

* rust-primitive-full-coverage: revert to Option (ii) — Mgr ratification-state-grep miss caught by valiant-ibex-312

valiant-ibex-312 ratification-state-grep at gunbc#1761
#issuecomment-4393074602 surfaced that origin/main HEAD has
TargetIntegerInhabitanceBound with 3 variants including
PlatformDependentFact (mirrors BoundDeclaration::PlatformDependent).
Earlier brief framing at 4229cd09d was against pre-PlatformDependentFact
state per codex BLOCKING reading; main moved since.

Option (ii) IS feasible: isize/usize rows populate via existing
PlatformDependentFact variant directly; u128 row populates StaticBoundFact
with BigInt-widened ExactInterval (Deliverable 1 unchanged). No
carrier refactor needed; 5 existing rows untouched.

Second Mgr-tier ratification-state-grep miss today (first was symbol-only
grep on T-Rule-Enumeration; now stale-codex-vs-current-HEAD on
TargetIntegerInhabitanceBound). Worker-tier discipline caught it before
sinking time into invasive Option (i.a) refactor.

Single-authority concern (parallel-named variants on
TargetIntegerInhabitanceBound vs BoundDeclaration) noted as future
substrate-fact-introduction; not blocking this slice — explicit-mirror
is the existing convention.

* rust-primitive-full-coverage: align Acceptance + Phase ordering + STOP triggers to Option (ii) (resolve codex internal-contradiction finding)

codex BLOCKING on PR #1929 sha 14f68b63 caught real internal contradiction: Context section flipped to Option (ii) feasible at 57ae4349b but Acceptance + Phase ordering still referenced BoundDeclaration migration / RustPrimitive bound field refactor from earlier Option (i.a) framing.

All sections now consistent with Option (ii):
- Phase 4 = no-op (TargetIntegerInhabitanceBound carrier untouched)
- Phase 5 = spec/rust.dag rows for isize/usize via existing PlatformDependentFact variant
- Phase 6 = u128 row via StaticBoundFact(IntInterval) + ratchet update
- Acceptance retargeted to row-population shape (no carrier refactor; existing 5 TargetIntegerTypeInhabitance rows untouched)
- STOP triggers retargeted to TargetIntegerInhabitanceBound variant-set sufficiency at HEAD
- Why-bundled rationale rewritten to Option (ii) shape (Phase A widening unblocks u128 StaticBoundFact; isize/usize use existing PlatformDependentFact)

codex BLOCKING #2 on PR #1929 sha 812602b4 caught: Acceptance + STOP triggers narrowed to Behavior-attributable lines but Deliverable 3 cementing-test step 4 still said 'every emitted line'. Now consistent — step 4 explicitly scopes to Behavior-attributable subset; declarations + program scaffold OUT-OF-SCOPE per same Finding #2 framing.

(codex BLOCKING #1 — claim that PlatformDependentFact NOT on main — is wrong; verified at origin/main HEAD: TargetIntegerInhabitanceBound has 3 variants including PlatformDependentFact. Rebut on PR.)

Per cursor review on PR #1782 (sha 2072b986):

1. L6 brief acceptance bullet at :131 still said "five types" while
   the parenthetical and the Slice step at :117 said six. The prior
   fix only caught one of two sites; corrected the second.

2. T-E-P brief `e_p_call_pattern_lookup_authoritative` acceptance
   named only `lower_call_pattern` as "the only route from call
   site to LoweringTarget" — but Phase 2 explicitly requires
   lenses route through `per_call_pattern_at` (the L-7 single-
   authority lookup), NOT `lower_call_pattern` (compiler-internal).
   Acceptance text rewritten to name `per_call_pattern_at` as the
   consumer-facing gate and clarify `lower_call_pattern`'s
   internal-only scope.

* fix(briefs): strengthen L6 ratchet from count-parity to per-row bijection

Per openai-pro REQUEST_CHANGES on PR #1782 (sha 2072b986): the L6
acceptance ratchet asserted only row-count parity between
emission_path_projections and the union of MethodTemplateContract
rows. Count parity permits duplicate projection keys and missing
source rows — the bridge from list-non-empty proxy to per-row
projection would not be mechanically proven. The whole point of
introducing MethodTemplateContractKey { target, dag_method } is to
provide 1:1 row identity.

Rewrites the ratchet to assert per-row bijection: every
MethodTemplateContract source row has exactly one matching
EmissionPathProjection row by key; every projection key resolves
to exactly one source row; duplicate projection keys fail closed.

(The other openai-pro BLOCKING finding — T-E-P
e_p_call_pattern_lookup_authoritative naming the wrong authority
— was already fixed at 6282a0704; the review citation was against
the pre-fix sha 2072b986.)

* fix(briefs): split L6 ratchet into slice-active vs deferred-activation gates

Per BLOCKING inline review on PR #1782 at d92459423: the prior
bijection ratchet was unsatisfiable as authored. The
*_method_template_contracts lists at HEAD (rust/python/go) are
non-empty; shipping emission_path_projections: [] alongside a
strict bijection requirement means the bijection cannot pass when
the slice lands — source rows would be uncovered. Prior text
incorrectly said "vacuously true on the empty source set" — the
SOURCE set isn't empty, only the projection set is.

Splits the ratchet into two gate categories:
- Slice-active gates: types/data shape exist + empty-state
  predicate (emission_path_projections == []).
- Deferred-activation gate: per-row key bijection, authored as a
  test scaffold by this slice but #[ignore]'d (or feature-gated
  on len > 0) until Grounding's follow-up populates rows. On
  activation, asserts the bijection over the populated set.

This honors P1 doc faithfulness: the slice's acceptance contract
is satisfiable as authored, and the bijection becomes the
load-bearing gate the row-population PR satisfies.

* fix(briefs): require L6 bootstrap enrollment to honor P2 facts-flow-forward

Per BLOCKING inline review on PR #1782 at L6:34: the slice authored
src/v3/std/cross_target_coverage.dag but never required enrolling
it in the bootstrap/load authority. Without enrollment the file
is dead-letter on disk and EmissionPathProjection can be absent
from the downstream Dag — silent P2 facts-flow-forward violation.

Adds a new Slice step 2 requiring a cross_target_coverage field
on BootstrapFixtures in src/v3/std/extdeps_bootstrap_fixtures.dag
mirroring the *_method_template_contracts enrollment pattern, plus
a loader-visibility ratchet. Renumbers subsequent Slice steps.
Adds matching Acceptance bullet.

* docs(briefs): normalize Practice 4 citation in S3 brief per codex review

Codex review on PR #1782 (sha 2614217e) flagged stale citation
"Practice 4 (Step 4 of the type-introduction checklist)" in
S3 brief — no such checklist step exists in the pinned rubric.

Live rule per docs/modeling-discipline.md:131-134 is the "What to
check" checkpoint-comment requirement under Practice 4 (coproduct
dissolution). Updated the S3 reference to cite that line directly
and drop the stale "Step 4 of type-introduction checklist" wording.

S2/S8/S9 already use bare "Practice 4" without the stale steps wording.
S1 (committed earlier today) does not contain the stale phrase.
S6 (pre-existing brief flagged by reviewer as carrying the same
pattern) is out of this branch's scope; flag for separate paydown.

* docs(briefs): sweep stale Practice 4 citations corpus-wide

Codex review on PR #1782 flagged the stale "Step 4 of the
type-introduction checklist" wording — no such checklist exists in
docs/modeling-discipline.md. The live rule is the "What to check"
checkpoint-comment requirement under Practice 4 (coproduct
dissolution) at docs/modeling-discipline.md:131.

Sweep across docs/ found 2 additional briefs carrying the stale
phrasing (S3 fixed previously at 9db003d40):

- docs/briefs/r3-l6-emission-path-projection-substrate-worker.md
- docs/briefs/r3-x1b-s1-transform-dispatch-substrate-worker.md

Both updated to cite the live rule directly. Verified zero
remaining "type-introduction checklist" or "Step 4 of the"
references in docs/ tree.

* docs(briefs): add Practice 4 citation discipline note to authoring checklist

Per parent inbox status flag at gunbc#828 #issuecomment-4385346221:
add a Citation discipline section to brief-authoring-checklist.md
naming the correct shape — Practice 4 (coproduct dissolution) +
"What to check" rule at docs/modeling-discipline.md:131 — and
calling out the stale "Step 4 of the type-introduction checklist"
phrasing as a failure mode. References the corpus sweep at
2dc92f34f.

Prevents future briefs that copy old templates from re-introducing
the stale citation pattern.

* docs(r3): cascade work post-Director ratification — S1 worker, R4 routing, Unit/Quantity canvas

Per Director ratification at gunbc#828 inbox response 2026-05-06
(zesty-bear-812):

1. S1 Q1+Q2 RATIFIED → author S1 gap-test representative worker brief
   (`r3-substrate-s1-gap-test-representative-worker.md`). Dispatchable
   on T-E-P Phase 1 + E6-G0d landing; closes ledger row #61.

2. S2 Q2 RATIFIED (option-(b) T-LBP narrowing) + S3 + S8 deferrals →
   R4 carve-out routing ledger (`docs/r4-carve-out-routing.md`).
   Captures C1 (parallelism lens), C2 (effect_enum lens), C3
   (register narrowing), C4 (deferred MachineConstraint axes),
   C5 (rounding-mode product extension), C6 (Unit/Quantity).
   Cascade messages to Verification / Grounding / Debt-Paydown Mgrs.

3. S9 Phase-3 dimensional refinement boundary → Unit/Quantity carrier
   canvas (`r3-substrate-s9-unit-quantity-carrier-canvas.md`).
   Surfaces Q-Unit-1..5 for Director ratification: carrier name,
   2-axis vs 3-axis Phase-1, Duration/Seconds collapse, Refined
   composition order, Practice 4 classification.

Updates §1.8 ledger receipts for carved items; R3 closure receipts
treat carved items as explicitly-deferred (not drift).

* docs(briefs): citation-discipline fix-forward — anchors/quotes, not line numbers

Director redirect at gunbc#828 #issuecomment-... noted the citation
paydown's replacement form (`docs/modeling-discipline.md:131`) is the
same drift class as the original fabricated-step error. Bare line
numbers shift silently on any doc edit above the cited line.

Generalized fix:
- brief-authoring-checklist.md "Citation discipline" section
  rewritten to prohibit bare line-numbers across ALL cross-doc
  references (modeling-discipline.md, r3-program-plan.md,
  r3-structure.md, INVARIANTS.md, MODELING.md, etc.). Use section
  anchors (#section-name) or rule-text quotes.
- 3 briefs that swapped in :131 (S3, S6, X1B) re-converted:
  - docs/modeling-discipline.md#4-coproduct-dissolution anchor
  - "What to check" rule quoted inline (self-contained)

Brief-authoring-checklist failure-mode section names both vectors
(fabricated step + bare line numbers) and references both sweep
commits in audit trail.

Broader cross-doc citation sweep across briefs I authored on this
branch (frontmatter authority-docs lists, body prose) is recommended
per Director note — flagging as separate paydown task; this commit
closes the immediate recurrence vector.

* docs(briefs): fix unfaithful Int=AbelianGroup<Nat> + sweep stale 'Step 4' refs

Per openai-pro review on PR #1782 sha 0ecd4818 (gunbc#1782 #...):

BLOCKING fix (P1 modeling faithfulness):
- S9 + S3 directed workers to model `Int = AbelianGroup<Nat>`,
  but Nat is not an Abelian-group carrier (additive inverses
  not representable). Reframed:
  - `Int` is the additive Abelian group on integers (carrier Z);
    `Nat` is a commutative monoid under addition.
  - Algebraic relationship is **explicit group-completion**:
    `Int ≡ GroupCompletion<CommutativeMonoid<Nat>>` — NOT
    `AbelianGroup<Nat>` parameterization.
  - Worker either models `Int` directly as `AbelianGroup`
    (terminal Abelian-group instance) OR introduces explicit
    `GroupCompletion<M>` substrate carrier; decision lands in
    Phase-1 PR per P1 procedure.
- S3 cross-reference + Phase-4 algebra-axis preservation note
  reframed accordingly.

NON-BLOCKING in-PR cleanup (Practice 4 citation discipline):
- 6 briefs still carrying stale 'Practice 4 Step 4' wording
  (r3-coproduct-1/2/3, r3-l6, r3-t-e-p, r3-x1b) updated to use
  the section anchor (`docs/modeling-discipline.md#4-coproduct-dissolution`)
  + inline rule-text quote ("What to check") form per the
  citation discipline established in `b4cae5299`.

Closes both findings from openai-pro review.

* docs(briefs): Q-Unit-1..5 RATIFIED — apply Scale.Unit→One rename + ratification banner

Director ratified Q-Unit-1..5 at gunbc#828 #issuecomment-... 2026-05-06
(zesty-bear-812). All 5 questions ratified; one rename required:

- Scale enum's `Unit` value collides with outer `Unit<Q, S>` carrier
  name (`Unit<Time, Unit>` is shadowing-confusing). Rename to `One`.
- Duration ≡ Unit<Time, One> (collapses with Seconds per Q-Unit-3).
- Milliseconds ≡ Unit<Time, Milli>.

Canvas updated:
- Top-level RATIFICATION banner records all 5 ratifications + rename
- Scale enum: `Unit` → `One` (with inline rename receipt)
- Sketch product expansions use `Unit<Time, One>` / `Unit<Time, Milli>`
- Phase-3 reframe table products updated
- Q-Unit-3 prose collapse reference updated

Subsequent worker brief authoring (Unit/Quantity carrier landing
post-prerequisite) inherits the renamed shape.

* docs(briefs): Unit/Quantity carrier worker brief — Q-Unit-1..5 RATIFIED

Worker brief consumes the ratified Unit/Quantity canvas
(`5f22fd06e` ratification banner). Phase-1 lands `Unit<Q, S>` +
`Quantity` + `Scale` declarations at the ratified shape (Scale's
`One` value per Q-Unit-1 rename). Phase-2 reframes S9 Phase-3
dimensional refinements (Duration / Seconds / Milliseconds) to
outer-Refined / inner-Unit composition per Q-Unit-4 RATIFIED.
EpochMs deferred to R4 C6 (Aspect-axis follow-up).

Practice 4 marks pre-determined per Q-Unit-5: `Unit<Q, S>` 🟢
PRIMITIVE; `Quantity` + `Scale` 🟡 SCAFFOLD with "consumed by ≥1
emission rule" dissolution trigger.

Cross-program handoff to Grounding Mgr (#1745) for dimensional
emission consumption documented.

Worker pin TBD — dispatchable when idle pool refreshes.

* docs(briefs): S9 Phase-1 reframed — Int landed at #1466; UInt-only migration

Per proud-lynx-311 dispatch ack at gunbc#1739 #issuecomment-...
2026-05-06: re-grep at HEAD revealed substrate state diverges
materially from S9 brief's "Option A vs B decide" framing.

Reality check at HEAD:
- `dsl/std/integer.dag:55` already carries
  `type Int = AbelianGroup<GroupCompletion<Nat>>` per Slice 3 PR
  #1466 / commit `4ba0a6d04`. Single-authority Q6 audit doc at
  `docs/audit/t-numeric-construction-group-completion-6q.md`
  ratified this shape and explicitly rejected the compact form.
- `dsl/std/integer.dag:56` still on legacy `type UInt = UInt64`
  alias; UInt migration is the actual Phase-1 worker scope.

Brief Phase-1 step 1 reframed: Int landing acknowledged; worker
confirms HEAD match. Phase-1 step 2 reframed: UInt migration
target named (`type UInt = CommutativeMonoid<Nat>`); fixed-width
rows preserved per existing legacy-rows policy.

Historical Option A vs B framing kept as note (superseded).

Confirmed S9 dispatch ack from worker; UInt-only Phase-1 PR is
in-scope. Emission entries deferred per S3 (valiant-ant-72
pre-landing); Phase-2 deferred per S8 (quiet-boar-160 pre-landing).

* docs(briefs): fix two BLOCKING citation drift items per codex review

Codex review on PR #1782 sha 5f22fd06 flagged two authority-receipt
gaps:

1. brief-authoring-checklist.md:118 — `<this-commit>` placeholder in
   the failure-mode section was unverifiable post-merge. Replaced
   with `b4cae5299` (the actual anchor/quote conversion commit).

2. r3-378-http-path-helper-fail-open-worker.md:84 — `INVARIANTS.md
   C-8 fail-closed` cited without anchor or rule-text quote, in
   violation of the citation discipline added in this PR.
   Converted to `INVARIANTS.md#p3-fail-closed` (P3 heading anchor)
   + inline rule-text quote naming P3 + C-8.

PR's own discipline now consistently applied across the diff.

* docs(briefs): sweep bare .md:NNN citations in Substrate-Mgr-authored briefs

Per Director recommendation in citation-discipline thread (gunbc#828
follow-on): bare line-number references drift silently. Swept 19
remaining instances across 5 briefs I authored on this branch:

- docs/briefs/r3-substrate-s1-q-class-2-chain-break-gap-test-canvas.md
- docs/briefs/r3-substrate-s1-gap-test-representative-worker.md
- docs/briefs/r3-substrate-s2-t-lbp-scope-calibration-canvas.md
- docs/briefs/r3-substrate-s3-machine-constraint-carrier-worker.md

Conversion: bare `file.md:NNN` → `file.md §"Section name"` form.
Stable; survives doc edits; human-readable. Section names per
HEAD heading audit.

Verification: `grep -nE '.md:[0-9]+' docs/briefs/r3-substrate-*.md
docs/r4-carve-out-routing.md` returns zero results in
Substrate-Mgr-authored scope.

Broader corpus scope (~232 references across non-Substrate briefs)
remains as separate paydown task.

* docs(briefs): fix BLOCKING + NON-BLOCKING items per openai-pro review on a462f007

Three findings addressed; 2 BLOCKING + 1 NON-BLOCKING:

BLOCKING — R3/R4 dual authority for Unit/Quantity carrier:
R4 carve-out C6 narrowed from "Unit/Quantity carrier landing"
(deferred all of it) to **"Aspect-axis (PointKind) follow-on
for EpochMs and instant/rate-shaped refinements only"**. The
2-axis Measure<Q,S> carrier landing IS in R3 per Q-Unit-1..5
RATIFIED; only the Aspect axis (PointKind = Magnitude | Instant
| Rate) carves to R4. Cascade-message C6 reference + R4 program-
plan input list updated to match. Cross-Mgr message clarifies
Grounding consumes 2-axis dimensional refinements in R3.

BLOCKING — Locked design partially applied (Scale.Unit→One
rename in canvas alternate-sketch sections):
- Canvas line 105-108 alternate sketch ("Open question: Instant
  vs Duration axis") still used pre-rename `Unit` Scale value;
  added pre-ratification disclaimer marking the section as
  deferred to R4 C6 + noting `Unit` is pre-rename
- Canvas line 163 Q-Unit-3 collapse note: `Scale = Unit` → `Scale = One`

(BLOCKING — bare line-numbers in S1 canvas frontmatter): NOT
APPLICABLE — already fixed at sweep commit 127287a66 prior to
review; reviewer was on sha a462f007 pre-sweep.

NON-BLOCKING — placeholder receipts:
- brief-authoring-checklist.md `#issuecomment-...` → concrete ID
  4385393971 (Director's anchor-discipline reply)
- r3-substrate-unit-quantity-carrier-worker.md (3 occurrences)
  + canvas RATIFICATION banner: `#issuecomment-...` → concrete ID
  4385412256 (Q-Unit ratification reply)
- `<this-commit>` placeholder in checklist already fixed at 5be1c99f2

Verification: zero `#issuecomment-...` or `<this-commit>` placeholders
in docs/briefs/ + docs/r4-carve-out-routing.md.

* docs(briefs): codex BLOCKING review fixes — Practice 4 source-level + policy scope

Three BLOCKING findings on PR #1782 (codex sha b913e2f4):

1. **Citation-discipline policy scope**: addressed by scoping
   the rule prospectively to briefs landing after the policy
   commit (`b4cae5299`). Pre-existing corpus references are
   flagged as paydown but NOT individually blocking; coordinated
   single-PR sweep is the right paydown shape. Substrate-Mgr scope
   already swept at `127287a66`.

2. **R4 C6 reconciliation**: already fixed at `6e5a5481a` (R4 C6
   narrowed to Aspect-axis follow-on for EpochMs only; 2-axis
   carrier landing IS in R3). Codex sha b913e2f4 was pre-fix.

3. **Practice 4 source-level vs PR-body conflation**: corrected.
   Acceptance bullet for Unit/Quantity worker brief now requires
   inline checkpoint comments on the LIVE declarations in
   `dsl/std/units.dag` (load-bearing artifact per
   `docs/modeling-discipline.md#4-coproduct-dissolution` "What to
   check"). PR-body summary is supplementary, not substitute.

Closes the review's reconciliation gates.

* docs(briefs): absorb Q-MachineConstraint + Q-Unit-1-Recanvas ratifications

Two major Director ratifications absorbed:

1. Q-MachineConstraint-Carrier RATIFIED at gunbc#828
   #issuecomment-4385530115 (Brian directive 2026-05-06: "universal
   substrate, ratify defaults"; PR #1817 queued). 6 sub-decisions:
   - MachineWidth<bits> only for R3; defer RegisterClass / EndianMode
     / Alignment / signedness post-R3
   - Parametric Compose<Algebra, MachineConstraint> type-level
     interaction shape (lookup-maps REJECTED — AlgebraMachineProduct
     record-keyed table form retracted)
   - Int<64> ≡ Compose<AbelianGroup, MachineWidth<64>> (algebra-side
     options A and B preserve interaction semantics)
   - Real<64> ≡ Compose<ApproximateField<Rational>, MachineWidth<64>>
     (algebra approx + machine approx as independent composing axes)
   - ≥3 pairs is minimum, not target
   - UNIVERSAL substrate: every target carries machine-constraint
     facts; targets without native machine-width semantics handle
     omission at Grounding-level discharge (target-conditioned
     lowering NOT target-conditioned substrate)

   Reframed: S3 brief Phase-1, S3 Phase-3/4 emission entries,
   S8 Phase-1/2/3 (ApproximateField<Real> → ApproximateField<Rational>;
   AlgebraMachineProduct → Compose<...>), S9 emission entries.

2. Q-Unit-1-Recanvas RATIFIED Measure<Q, S> at gunbc#828
   #issuecomment-4385539791. valiant-ibex-312's substrate-state
   grep caught Unit<Q, S> collision with kernel Unit at
   dsl/std/types.dag:176; Director ratified Measure<Q, S> as
   outer carrier name (conventional in scientific computing;
   no dsl/std/ collision).

   Reframed: Unit/Quantity worker brief throughout (Unit<Q,S> →
   Measure<Q,S>; dsl/std/units.dag → dsl/std/measure.dag); canvas
   spec sections + sketch products (Refined<Measure<Time, ...>...>);
   R4 carve-out C6 with informal/formal name disambiguation note.

Both rename + reshape are now consistent across S3 / S8 / S9 /
Unit-Q briefs + canvas + R4 routing. Workers (valiant-ant-72 on S3,
quiet-boar-160 on S8, proud-lynx-311 on S9, valiant-ibex-312 on
Unit-Q) all dispatch against the ratified shape.

* docs(briefs): S11 Slice C worker brief — ROADMAP :425 retirement post-#1801

Cascade-clearance trigger fired post-#1801 (Slice B) merge
2026-05-06. S11 brief authored per B1 RATIFIED prose+regen
bundling discipline.

Phase 1: per-file edits across the post-A+B residual list (~10
files per smart-ram-167's Slice B post-rebase enumeration);
anchor + rule-text-quote pattern per current citation discipline;
bootstrap regen in same PR (no split).

Phase 2: ROADMAP :425 row PARTIAL → Retired with 3-slice receipt;
Q-Slice-C-Retirement-Receipt resolution.

Worker pin smart-ram-167 (#1759) — Slice B precedent owner.
Dispatch packet sent separately to #1759.

* docs(briefs): Q-Refined-Phantom-Composition (c) RATIFIED — defer literal Refined form

Director ratified option (c) at gunbc#828 #issuecomment-... 2026-05-06:
drop `non_negative` predicate at Measure (phantom) layer; rely on
`Quantity = Time` tagging for non-negative-magnitude semantics.

Q-Unit-4 outer-Refined / inner-Measure composition is preserved as
**conceptual model**; the literal `Refined<Measure<...>, predicate>`
form is **deferred to value-typed-integration follow-up** when
substrate gains Refined<> as first-class type expression and
dimensional refinements get value-typed integration.

Updates:
- Canvas RATIFICATION banner Q-Unit-4 row reframed to "conceptual
  model; literal form deferred"
- Canvas Phase-3 reframe table: Duration / Milliseconds drop the
  Refined<...> wrapper; rely on Quantity tag
- Worker brief Phase-2 prose + reframe table + Acceptance bullet
  all reflect deferred-literal-form posture

valiant-ibex-312 unblocked to proceed with Phase-2 (Grounding
handoff doc) per the (c)-shaped Acceptance.

* docs(briefs): S12 F2 + F8 doc-sharpening worker brief — post-#1820 cascade

#1820 (Slice C) merged 2026-05-06; ROADMAP :425 row Retired closes
the prose-reference paydown program. S12 cascade-clearance trigger
fires per B6 RATIFIED single bundled Mgr-tier doc-sharpening PR.

Scope: F2 (.v3 filename-suffix grammar dispatch) + F8 (bootstrap
load-order/exclusion authority) — single bundled PR per B6.
Cross-program coordination with PB Mgr (#1742) per design schedule
§3 P5 (comment-only OR co-author; no duplicate PR).

Worker pin smart-ram-167 (#1759) — Slice C precedent owner;
pattern-familiar with prose+regen bundling discipline. Dispatch
packet sent separately to #1759.

* docs(briefs): S9 brief — UInt landed via #1818; algebra label corrected to CommutativeSemiring

Per proud-lynx-311 merge report at gunbc#1746 #issuecomment-...
2026-05-06: PR #1818 landed `type UInt = Nat` after codex BLOCKING
review on initial `CommutativeMonoid<Nat>` form (P2 facts-flow-forward
violation — wrap projects out Nat's multiplicative monoid + identity 1).

Final landed form preserves full `CommutativeSemiring<Magnitude>`
surface — Nat IS a commutative semiring (addition + multiplication
+ 0 + 1). Algebra-side label for UInt is CommutativeSemiring, NOT
CommutativeMonoid (corrects my earlier dispatch labeling).

S9 Phase-1 step 2 marked LANDED with merge ref. Phase-1 step 3
emission entries reframed:
- Int<N> ≡ Compose<AbelianGroup, MachineWidth<N>>
- UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>>

Worker discipline + reviewer caught a substrate-state error in my
brief framing; brief now matches landed reality.

* docs(briefs): fix contradictory (c) guidance in Unit/Quantity worker brief

Codex BLOCKING review on PR #1825 sha 1bce0418 caught a real
contradiction: brief Phase-2 prose at lines 115-118 stated
"predicates do NOT attach at the Measure (phantom) layer" per
Q-Refined-Phantom-Composition (c) RATIFIED, but immediately
following paragraph at lines 130-132 still said "Refined predicate
non_negative applies at the Measure-typed level" — left over from
the original Q-Unit-4 framing.

Updated lines 130-137 to consistently apply (c) shape: predicates
deferred to value-typed-integration follow-up; dimensional semantics
ride on Quantity tag at Measure layer; worker authors 3 in-scope
refinements WITHOUT predicate at this layer.

P2 boundary discipline restored: brief now gives single-authority
guidance for Phase-2 substrate landing.

* docs(briefs): name predicate authority + concretize ratification ID — codex BLOCKING

Codex BLOCKING review on PR #1825 sha 32541a56:

1. (BLOCKING) Q-Refined-Phantom-Composition (c) ratification deferred
   phantom-carrier predicates without naming the value-level predicate
   authority. Updated canvas Q-Unit-4 RATIFICATION row to explicitly
   name: 'predicates re-attach at value-typed Int/UInt level via
   where-sugar (e.g., range(min: 0) per current dsl/std/types.dag
   precedent)' when value-typed integration lands.

2. (BLOCKING) Worker brief option-c reframe didn't sweep the audit
   receipt §5 (Carrier dissolves the bridge). Updated to consistently
   apply (c) shape — dimensional semantics ride on Quantity tag at
   Measure layer; value-level predicate authority deferred; until
   then, range/gt_zero constraints attach at value-typed Int/UInt
   via where-sugar per dsl/std/types.dag convention.

3. (NON-BLOCKING) Canvas had #issuecomment-... placeholder for the
   (c) ratification message ID. Replaced with concrete
   #issuecomment-4385687075 per dashboard relay header.

Brief now names a single value-level authority (Int/UInt where-sugar)
for value-range facts; phantom-layer Quantity tag carries only
dimensional semantics. P2 boundary discipline maintained.

* docs(briefs): S12 RETIRED per Director option (2) ratification

Director ratified option (2) at gunbc#828 #issuecomment-4385873...
2026-05-06 post smart-ram-167's substrate-state STOP-AND-ESCALATE:

- F2 absorbed by 2026-05-04 routing + #1662 closure
  (`Result/DivError span.file-keyed` retired)
- F8 topical concerns distributed across live rows
  (Class 5 Gap 3 `bootstrap.rs::std_fixtures()`; Character-level
  load-set / bootstrap; Filename-sentinel-bridges) with own owners
- Doc-discipline goals absorbed by per-Mgr citation paydown
  routing at gunbc#828 #issuecomment-4385583247

Frontmatter updated to RETIRED with absorption receipt. Worker
(smart-ram-167) pin freed.

Director-side acknowledgment of Substrate Mgr's option (2) recommendation:
"Substrate Mgr's option (2) recommendation is the right move
structurally. Most Mgrs default to 'synthesize work to fill the brief'
when canvas-vs-HEAD mismatch surfaces. Recommending retirement when
the work is genuinely absorbed is harder discipline."

* docs(briefs): S7 PR-F (BoundDeclaration consumer + ReferenceModel<T>) worker brief

Per cascade-clearance trigger fired post-#1782 merge 2026-05-06.
loyal-wolf-828 (#1764) acknowledged S7 dispatch with substrate-state
pre-flight grep (gunbc#1764 #issuecomment-4385872...) and surfaced
await-brief posture. This brief satisfies that prerequisite.

Worker pre-flight inventory absorbed:
- BoundDeclaration substrate landed (substrate.dag StaticBound +
  PlatformDependent); partial BoundDeclarationView consumer in
  fold.rs (ScratchIntExamples scope; doc-explicit partial)
- ReferenceModel<T> NOT yet in dsl/std/ (substrate-fact-introduction
  required; design-emission-model.md §Q2 framing)

Phase-1: BoundDeclaration consumer broadening to full
design-emission-model.md surface (u128 / isize / usize / walker
arms / pilot mirror).

Phase-2: ReferenceModel<T> P1 substrate-fact-introduction with
DFS-of-concept-DAG + Practice 4 in-source checkpoint comment +
named consumer demand (Grounding G1).

Phase-3: cross-program handoff to Grounding Mgr (#1745) for
G1 (T-Ground-Rust Phase 1).

Closure predicate: unblocks Grounding T-Ground-Rust Phase 1.
Worker pin loyal-wolf-828 holds; dispatch fires immediately

* docs(briefs): S9 Slice 2.5 — predicate-registry + PB-1 shim retirement (Path 3 RATIFIED)

Director ratified Path 3 at gunbc#828 #issuecomment-4390333451
post proud-lynx-311's pre-flight DFS at gunbc#1746 #issuecomment-4390253616.

Brief reframes Slice 2.5 from S-sized (primitive + 1 consumer) to
L-sized (predicate registry + PB-1 shim retirement). 5 deliverables:
1. gt_zero primitive predicate
2. Predicate registry infrastructure (resolver-side substrate-fact-introduction)
3. PB-1 shim retirement (span.file=='dsl/std/types.dag' special case dissolves)
4. Migration of existing types.dag predicates (range, pattern, etc.)
5. PositiveInt = Refined<Nat, gt_zero> consumer update

Per Director hard scope bars: no parallel predicate-resolution path;
no per-call-site special-casing; PB-1 shim retirement non-negotiable
in same slice. Single PR per Path 3 RATIFIED.

Discipline anchors: feedback_construction_over_ratchets (PB-1 shim
is bridge); feedback_dissolve_bridges (registry is structural fix);
feedback_no_textual_enforcement_bridges (file-path special-case is
anti-pattern shape); P1 substrate-fact-introduction procedure.

Worker pin proud-lynx-311 — Director pre-cleared on pre-flight DFS
context. PR #1840 (partial Slice 2 — NonNegativeInt = Nat) MERGED
at 16:54Z; Slice 2.5 dispatchable immediately on this brief landing.

* docs(briefs): Slice 2.5 audit receipt — Mgr independent grep parallel-verifies worker DFS

Codex BLOCKING review on PR #1845 sha 2d230949 flagged: external PR
receipt absorbed as live substrate state without re-grepping local
std declarations at brief authoring time. Authority receipt §1
cited proud-lynx-311's pre-flight DFS as authority but didn't
record Mgr-side independent verification.

Updated audit receipt §1 + §4 to record Mgr's independent grep at
HEAD as parallel verification:
- gt_zero zero matches in dsl/std/ + src/v3/ (verified)
- NonNegativeInt = Nat at dsl/std/integer.dag:133 (#1840 land)
- PositiveInt = Int where range(min: 1) at dsl/std/types.dag:255
- PB-1 shim doc-block confirms bridge-text framing
- Predicate registry confirmed not present

Worker DFS remains the dispatch-time discipline (substrate-state
grep at dispatch); Mgr's independent grep is parallel verification,
not substitute. Per Director's pattern note at gunbc#828
#issuecomment-4390199218 + #issuecomment-4390333451: dispatch-packet
authoring discipline includes Mgr-side substrate-state-grep, not
just relay of worker findings.

* docs(briefs): Slice 2.5 brief — Int extensibility scope-bound; lower.rs cites anchored

openai-pro REQUEST_CHANGES on PR #1845 sha 2d230949 flagged 2 issues:

BLOCKING — P1 modeling faithfulness / substrate scope leak:
`gt_zero` Int-side extensibility was left to 'worker judgment if
generalization cheap'. Per feedback_construction_over_ratchets:
don't speculatively extend predicate-carrier compatibility ahead
of named consumer demand. Reframed to **EXPLICITLY OUT-OF-SCOPE**
for Slice 2.5; Nat-only registration. Future Int-side consumer
surfaces as separate substrate-fact-introduction (P1 procedure)
brief with own consumer-demand receipt.

NON-BLOCKING — citation discipline self-violation:
3 instances of bare `lower.rs:821-835` line-range citations
contradict the brief's own 'no bare :NNN' requirement at line 211.
Converted to function-name anchored form:
`src/v3/compiler/src/lower.rs` (`lower_type_alias_refinements_phase` doc-block).

Both findings absorbed; no parallel scope ambiguity remains;
brief now self-consistent on citation discipline.

* docs(briefs): Slice 2.5 brief — Path (a) RATIFIED carrier+argument contract verification

Director Path (a) RATIFIED at gunbc#828 #issuecomment-4390760353
(triage) + #issuecomment-4390794121 (convergence ack):
predicate-body lowering with carrier+argument contract
verification at lower-time IN SAME SLICE. Placeholder semantics
REMOVED from registry path.

Codex REQUEST_CHANGES surfaced that registered-predicate-without-
contract = silent acceptance per feedback_fail_closed_discipline.
Brief reframe absorbs Path (a):

Hard scope bar #5 added:
- Same-slice carrier+argument-contract verification
- Mismatched carrier OR malformed argument → Diagnostic::ResolveError
- No 'named but not checked' path remains

Scope expansion section added (L → XL):
- Predicate-body lowering for all 7 registered predicates
- Per-predicate arg-shape validation
- Multi-session work acknowledged
- Carrier-check at 788d6acb4 retained; predicate-body builds on top

Acceptance bullets updated: gt_zero with arg-shape validation +
all 7 predicates with carrier+argument contract verification.

Director-pinned brief-authoring discipline: dissolution trigger
named in a brief authored as substrate-fact-introduction must
specify same-slice acceptance, not deferred follow-up. Otherwise
the brief encodes 'land bridge + defer dissolution' anti-pattern,
the same shape feedback_construction_over_ratchets warns against
at implementation layer applied at brief authoring layer.

This is the 11th miss this session — but the pattern surfacing it
(direct sweep + Codex REQUEST_CHANGES + Director ratification)
produces structural fixes that prevent the next miss class. Brief
revision is the structural recovery.

* docs(briefs): Slice 2.5 brief — Path 2 RATIFIED (Gap 1 discharge + Q-Regex carve-out)

Director Path 2 RATIFIED at gunbc#828 #issuecomment-4391985613
post Rung 3 STOP at gunbc#1746 #issuecomment-4391946213.

Path 2 narrowing of Path (a):
- gt_zero + range body synthesis already landed (5f3c40c3a)
- Gap 1 discharge mechanism: extends scalar-literal predicate
  evaluation at lower-time. L-class; lands SAME SLICE per
  same-slice-dissolution discipline
- non_empty + brand body synthesis: lands via Gap 1 discharge
- pattern / format / content: fail-closed-with-named-dep at
  user-code authoring layer (Diagnostic::ResolveError naming
  Q-Regex-Primitive). NOT placeholder; structural rejection
- PB-1 shim FULLY RETIRED per hard scope bar #3
- Q-Regex-Primitive carved as follow-on substrate-fact-introduction
  (XL substrate; not pre-authored per feedback_construction_over_ratchets)

Acceptance updated:
- 4 of 7 body-synthesized in same slice
- 3 of 7 fail-closed-with-named-dep (no placeholder semantics)
- Gap 1 discharge mechanism landed (no partial implementation)

Worker disposition: proud-lynx-311 continues Rung 3 with Gap 1
implementation + non_empty/brand body synthesis + pattern/format/
content fail-closed-with-named-dep diagnostic.

* docs(briefs): S9 Phase-1 Step 3 emission entries — Tier-1 brief authoring (1/5)

- UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>> → Rust u32/u64/u128
- 6 concrete instantiations (≥3 minimum per sub-decision 5)
- Cross-program handoff to Grounding Mgr (#1745) for G2 emission consumption
- numeric_construction_demonstration Acceptance bullet (Int<32> round-trip);
  Real<64> half deferred to S9 Phase 2 / S8 Float cascade

Brief authored with substrate-state-grep discipline + same-slice-
dissolution discipline (no deferred trigger; demonstration in same
slice or explicitly carved). 5-question authority audit completed
in brief body.

Worker pin proud-lynx-311 (S9 holds); brief queues post-Slice-2.5

Authored per Director freed-pool pressure at gunbc#828
#issuecomment-4392095857 + Tier-1 brief-queue commitment.

Brief covers parser-grammar surface for Compose<Algebra, MachineConstraint>
interaction syntax post-#1856 (Phase-1 carrier slice landed):

- Phase 2.1: Parser surface per ratified Q-MachineConstraint-Grammar-Shape
- Phase 2.2: Bootstrap demonstrator with >=3 algebra*machine-axis pairs
- Phase 2.3: Class 1 5-criteria Pass receipt (criteria 1-4; criterion 5
  v2-oracle parity may carve)
- Phase 2.4: numeric_construction_demonstration co-receipt with S9 Phase-1
  Step 3 emission entries brief

Director ratification HOLDS on grammar bikeshed:
- Candidate A: Int @ Width<32> (annotation form)
- Candidate B: Int with MachineWidth<32> (with-form)
- Candidate C: Int<32> (positional generic — fits existing convention)
- Candidate D: Compose<AbelianGroup, MachineWidth<32>> (no parser change;
  type aliases provide convenience names)

Worker pin valiant-ant-72 holds (S3 Phase-1 precedent owner); freed-pool
until Director ratifies grammar shape.

Tier-1 brief queue progress: 2/5 authored (this brief + S9 Phase-1 Step 3).
Remaining: S9 Phase-2 Float coordination; T-LBP complexity cementing;
T-LBP cost cementing.

* docs(briefs): S3 Phase-2 brief — fix internal contradiction on Class 1 closure scope

Codex BLOCKING review on PR #1889 sha ec609b4a flagged real
contradiction:

- Provenance section claimed '5-criteria Pass closed' (line 229)
- Phase 2.3 said 'criterion 5 may queue separately' (line 154)
- STOP-AND-ESCALATE bullet 1 ratified 4-of-5 carve-out (line 181)

Updated Provenance to consistently state criteria 1-4 close in this
slice; criterion 5 (v2-oracle parity) cementing test may carve to
separate slice. Single 4-of-5 framing throughout. INVARIANTS.md
'Documentation Describes Live State' satisfied.

Per feedback_construction_over_ratchets: don't claim closure that
isn't structurally complete. 4-of-5 + named carve is the honest
shape; 5/5 only on cementing-test land.

- 4 predicates body-synthesize via Gap 1 (gt_zero / range / non_empty
  / brand)
- pattern / format / content STRUCTURALLY ABSENT from registry (not
  pending-with-placeholder); user-code where-clause produces
  Diagnostic::ResolveError naming Q-Regex-Primitive as separate
  substrate-fact-introduction follow-on
- ~12 types.dag refined-type declarations migrate to drop
  pattern/format/content where-clauses with inline-comment receipts
  pointing to Q-Regex restoration path; 1 extdep (sts_endpoint)
  adapts as needed
- PB-1 shim FULLY RETIRED — no exception, no preserved branch
- Q-Regex-Primitive as separate brief / worker pin / Director
  ratification cycle when concretely needed (Option B XXL bundling
  REJECTED)

handoff at gunbc#846 #issuecomment-4392510255.

Two real substrate-shape questions stacked:

provenance is per-emitted-line. 4 options surfaced — (a) per-Behavior
Lens-compatible / (b) per-line instrumentation NOT a lens / (c)
withdraw + re-canvas / (d) Mgr-surface both substrates distinct.
Mgr recommends (d) if visualization is load-bearing; (a) suffices
if per-Behavior aggregate works for the slide. Brian-channel
sub-question surfaced.

Q2 (fold-rule enumerability): T-Rule-Enumeration substrate-fact-
introduction is prerequisite for every Q1 path (rust_target.rs uses
inline &str template names; rules not enumerable). Mgr recommends
parallel-dispatch with Q1 deliberation — satisfies Brian's ASAP
framing while shape ratifies.

Q3 (§1.8 ledger retarget): #89 already taken by T-LAS; new cluster
location follows Q1 disposition.

EmissionOrigin (sibling row emission_origin_classification_green to
parent emission_provenance_lens_landed gate).

* briefs: Practice 4 terminal receipt for EmissionOrigin + bound for β scaffold

Address openai-pro BLOCKING (sha f36e1205, ran post-rubric-rename):

1. EmissionOrigin GREEN terminal classification needs documented
   attempted-dissolutions per modeling-discipline.md "no richer
   source exists" framing. Added 3 attempted dissolutions:
   - collapse to optional-pair (rejected by codex Finding 1 prior)
   - factor common richer source (orthogonal payload types prevent)
   - third arm for unattributable lines (rejected per Slice 2.5
     Option 4 placeholder anti-pattern)

2. T-Rule-Enumeration β (YELLOW) scaffold needs bound per three-part
   bridge rule. Added: allowed call sites scoped to emission code only;
   max lifetime gated on rule_name_typo_fail_closed_landed graduation;
   new emission-introspection consumers MUST author against closed-sum
   α form, not β.

* WIP: R3 Substrate

* briefs: address codex BLOCKING bundle (sha 2ed1046e) — record-form provenance + emit_model carrier alignment + T-Rule-Enumeration retirement flag

Three findings addressed:

1. Lens brief (Finding #1 — provenance shape conflates source vs rule
   attribution): replaced typed-sum EmissionOrigin with record
   EmissionProvenance { rule: EmissionRule [mandatory], source_span:
   Option<SourceSpan> [optional] }. Co-inhabitance is real (e.g.,
   #[derive(Debug)] line has both rule=derive_for_disj AND span
   attribution to Foo decl). Rule-mandatory enforces fail-closed
   structurally; Practice 4 N/A (record, not coproduct).

2. T-Rule-Enumeration brief (Finding #2 — rule authority lives in
   spec/rust.dag + v3.std.emit_model, not call-site strings): brief
   status flipped to FLAGGED FOR RETIREMENT. Same finding as
   smart-ram-167 STOP at gunbc#1759 #issuecomment-4392696623; Reading
   C surfaced to Director at gunbc#828 #issuecomment-4392780871.

3. Rust-primitive-full-coverage brief (Finding #3 — BoundDeclaration
   not wired into TargetIntegerInhabitanceBound row surface):
   reframed Deliverable 2 to target the actual carrier
   `v3.std.emit_model::TargetIntegerInhabitanceBound` (used by
   `TargetIntegerTypeInhabitance` rows in src/v3/spec/rust.dag lines
   169-207). Two paths surfaced: Option (i) wire BoundDeclaration into
   TargetIntegerInhabitanceBound; Option (ii) populate via existing
   variants if PlatformDependent already exists on the live carrier.
   Worker DFS at dispatch picks. Deliverable 3 retargeted to
   TargetIntegerTypeInhabitance rows (the actual surface).

* rust-primitive-full-coverage: codex inline confirms TargetIntegerInhabitanceBound has no PlatformDependent variant — Option (ii) infeasible; carrier refactor REQUIRED

Codex BLOCKING inline at PR #1910 line 65 (sha 98507c432) verified at
HEAD: TargetIntegerInhabitanceBound = BoundUnspecified | StaticBoundFact(IntInterval).
No PlatformDependent variant. Earlier brief framing of Option (ii)
(populate via existing variants) was infeasible.

Brief reframed: carrier refactor is required (not optional). Two
structural shapes for the refactor — (i.a) embed BoundDeclaration
(Mgr recommendation; single-authority discipline) vs (i.b) extend
variant set with PlatformDependent. Existing 5 rows migrate either
way; bootstrap snapshot semantic-equivalence non-negotiable.

* emission-provenance lens brief: absorb codex BLOCKING bundle (sha 4229cd09 post-merge findings)

Two findings from codex bundled review on now-merged PR #1910 sha
4229cd09 land as brief revisions for the in-flight smart-ram-167
authoring cycle (PR #1928):

1. Field-path identity threading: render_named_template call sites
   receive template values extracted from binding structs; field-path
   may not be carried alongside the value at emission time. New STOP
   trigger flags this as substrate-cascade if threading isn't
   structurally possible (typed template-with-rule-path or
   DeclarationRef carrier needed).

2. Read domain coverage gap: Lens<C>.read is per-Behavior; emitted
   output also includes declarations + program scaffold. Acceptance
   scope explicitly narrowed to Behavior-attributable lines only;
   declarations + scaffold provenance out-of-scope (separate substrate
   cascade if surfaced). Acceptance bullet retargeted to
   "Behavior-attributable span-Some + Behavior-attributable span-None"
   rather than full-emission coverage.

* rust-primitive-full-coverage: revert to Option (ii) — Mgr ratification-state-grep miss caught by valiant-ibex-312

valiant-ibex-312 ratification-state-grep at gunbc#1761
#issuecomment-4393074602 surfaced that origin/main HEAD has
TargetIntegerInhabitanceBound with 3 variants including
PlatformDependentFact (mirrors BoundDeclaration::PlatformDependent).
Earlier brief framing at 4229cd09d was against pre-PlatformDependentFact
state per codex BLOCKING reading; main moved since.

Option (ii) IS feasible: isize/usize rows populate via existing
PlatformDependentFact variant directly; u128 row populates StaticBoundFact
with BigInt-widened ExactInterval (Deliverable 1 unchanged). No
carrier refactor needed; 5 existing rows untouched.

Second Mgr-tier ratification-state-grep miss today (first was symbol-only
grep on T-Rule-Enumeration; now stale-codex-vs-current-HEAD on
TargetIntegerInhabitanceBound). Worker-tier discipline caught it before
sinking time into invasive Option (i.a) refactor.

Single-authority concern (parallel-named variants on
TargetIntegerInhabitanceBound vs BoundDeclaration) noted as future
substrate-fact-introduction; not blocking this slice — explicit-mirror
is the existing convention.

* rust-primitive-full-coverage: align Acceptance + Phase ordering + STOP triggers to Option (ii) (resolve codex internal-contradiction finding)

codex BLOCKING on PR #1929 sha 14f68b63 caught real internal contradiction: Context section flipped to Option (ii) feasible at 57ae4349b but Acceptance + Phase ordering still referenced BoundDeclaration migration / RustPrimitive bound field refactor from earlier Option (i.a) framing.

All sections now consistent with Option (ii):
- Phase 4 = no-op (TargetIntegerInhabitanceBound carrier untouched)
- Phase 5 = spec/rust.dag rows for isize/usize via existing PlatformDependentFact variant
- Phase 6 = u128 row via StaticBoundFact(IntInterval) + ratchet update
- Acceptance retargeted to row-population shape (no carrier refactor; existing 5 TargetIntegerTypeInhabitance rows untouched)
- STOP triggers retargeted to TargetIntegerInhabitanceBound variant-set sufficiency at HEAD
- Why-bundled rationale rewritten to Option (ii) shape (Phase A widening unblocks u128 StaticBoundFact; isize/usize use existing PlatformDependentFact)

* lens brief: narrow Deliverable 3 verification step 4 to Behavior-attributable lines (resolve codex #2 consistency)

codex BLOCKING #2 on PR #1929 sha 812602b4 caught: Acceptance + STOP triggers narrowed to Behavior-attributable lines but Deliverable 3 cementing-test step 4 still said 'every emitted line'. Now consistent — step 4 explicitly scopes to Behavior-attributable subset; declarations + program scaffold OUT-OF-SCOPE per same Finding #2 framing.

(codex BLOCKING #1 — claim that PlatformDependentFact NOT on main — is wrong; verified at origin/main HEAD: TargetIntegerInhabitanceBound has 3 variants including PlatformDependentFact. Rebut on PR.)

…pendencies (codex BLOCKING)

codex inline BLOCKING @ docs/audit/r3-r4-carve-substrate-readiness-2026-05-09.md:112: prior cascade chain "C3 cascade-gates on parallelism lens BEHAVIORALLY COMPLETE" understated the lane-level dependency.

Per r3-structure.md:61: T-Lens-Application-Surface lane depends on T-Lens-Behavioral-Parity COMPLETE (all 4 in-R3 lenses: complexity #79 + cost #80 + parallelism #81 + effect_enum #82), not only C1.

Fix: §3.1 distinguishes:
- Lane-level (T-LAS Slice B substrate authoring complete): gates on full T-LBP COMPLETE.
- Gate-level (#95 specific demo): gates on parallelism-lens projection within Slice B + parallelism BEHAVIORALLY COMPLETE (C1).

Both dependencies named explicitly. The simplified "cascade-gates on Slice B + C1" framing was correct for #95-specific firing but understated the lane-level closure dependency.

codex inline BLOCKING @ docs/audit/r3-cluster-f-sequencing-plan-2026-05-09.md:22: prior single-phase F-γ collapsed two gates with different prerequisite sets — only #95 cascade prerequisites named (post-F-α + T-LAS Slice B), allowing #83 register to be scheduled before cost (#79) / effect_enum (#82) completion.

Fix: F-γ split into F-γ.1 + F-γ.2 with distinct cascade prerequisites:
- F-γ.1 (#95 demo): cascade post-F-α (parallelism BEHAVIORALLY COMPLETE) + T-LAS Slice B (per-lens LensEnforcement projection)
- F-γ.2 (#83 register full-scope): cascade post-ALL 4 lenses BEHAVIORALLY COMPLETE — F-α (#81 parallelism) + F-β (#82 effect_enum) + #79 (complexity, T-LBP existing) + #80 (cost, T-LBP existing)

…or-greenlit (α) carve-promotion-IN-R3) (#2363)

* docs(audit): R3 R4-carve substrate-readiness audit (C1/C2/C3) — Director-greenlit per (α) ratification

Per Director ratification at gunbc#846 #issuecomment-4412330468 (2026-05-09): RATIFIED PM (α) carve-promotion-IN-R3 recommendation per operator's 2026-05-09 framing "R3 close = 0 hand-Rust including tests AND stage0; bootstrap is data + self-generated."

Substrate-readiness audit findings:

**C1 #81 parallelism lens**: substrate-ready. effects.dag provides EffectShape/OperationEffect/CompositionVerdict; workflow_parallelism.rs imports map cleanly; port-and-rewire bounded (M-sized lane). RECOMMENDATION: full carve-promotion to R3.

**C2 #82 effect_enumeration lens**: MIXED. 4a/4b/4d bounded (consumer migration + cleanup); 4c (caller-side effect-set pinning carrier) is NEW P1 substrate-fact-introduction not landed at HEAD. RECOMMENDATION: Director disposition between (a) full carve-promotion with 4c canvas authoring in R3 (PM-recommended per strict-zero framing) OR (b) γ .dag-stub-form interim with 4c R4-carved.

**C3 #95 opt-in iteration parallelism via lens application**: substrate-ready conditional on C1. lens_application.dag exists; cascade-gated on C1 BEHAVIORALLY COMPLETE. RECOMMENDATION: full carve-promotion to R3 (cascade post-C1).

Cluster F sequencing folder: #81 + #82 + #95 fold into existing T-LP-Retirement (lens-producer-retirement structural framing). Sub-phase α (#81 port) + β (#82 per disposition) + γ (#95 demo cascade post-α).

Velocity-to-zero update: original 4-6 bulk events → 5-9 bulk events post-carve-promotion. Bounded substrate/cluster work per "staffing not concern."

Out-of-scope follow-ups: UNACCOUNTED entries in non-test census (Director's separate ask) — handled in Task 13 follow-up audit, not this artifact.

* fix(audit): §0 + §2.3 — P1 modeling-vs-process layers + decision-state scope clarification (openai-pro REQUEST_CHANGES)

openai-pro review on PR #2363 sha c3a4b11: 2 valid findings.

**Finding 1 — P1 substrate-fact-introduction procedure misrepresented**:
§2.3 line 87 cited "INVARIANTS.md P1 procedure" but listed 4 dispatch/process gates (confirmed bridge consumer / carrier shape ratification / worker brief authoring / substrate-introduction PR). The actual P1 procedure (INVARIANTS.md:94-129) is 3 modeling checks: DAG-ancestor / coproduct-vs-coordinate / primitive-vs-lens-extensible. Folding both into one "P1" label authorizes carve-promotion without proving the new carrier is the right substrate fact.

Fix: §2.3 now explicitly separates two layers — Layer 1 is the actual P1 modeling checks (cited with line references INVARIANTS.md:100-128); Layer 2 is dispatch/process gates. Layer 1 must surface in canvas authoring before carrier shape ratification; Layer 2 is the dispatch sequence. Both required.

**Finding 2 — Decision-state ambiguity (α ratified vs C2 disposition open)**:
Doc said audit is per Director (α) ratification but kept C2 as "Director disposition needed" — read as competing decision states. Cluster F dispatch couldn't tell whether (a) is ratified or γ-stub remains alternative.

Fix: §0 adds explicit scope clarification — (α) thesis (carves dissolve; #81/#82/#95 R3-load-bearing) is RATIFIED at thesis level; C2 #82 sub-disposition (a vs γ-stub) is finer-grain decision *within* (α) framework. Both paths satisfy operator strict-zero framing; they differ on R3 (path (a)) vs R4 (path (γ)) timing of #82's behavioral completion. Two scopes, no contradiction.

* fix(audit): C2/C3 substrate-readiness — design-doc authority + Slice B scope (codex BLOCKING round 1)

codex top-level BLOCKING on PR #2363 sha c3a4b11: 4 findings, 3 of which were new (Finding 2 already addressed at e54d880). Major C2 + C3 corrections:

**Finding 1 — C2 audit relied on grep names instead of locked design authority**:
Prior framing claimed 4c (caller-side effect-set pinning carrier) is NEW substrate-fact-introduction. Verified against locked design at docs/design-effect-enumeration-resource-threading.md §3.2 + §6.2: "The pinning substrate carrier ALREADY EXISTS at src/v3/std/services.dag::Operation. No new top-level carrier is required." §6.2: "Operation already exists. No new substrate type."

Carve doc's "4c is NEW substrate intro required" claim is stale relative to the more recent locked design. C2 is substrate-ready (atomic migration shape per §6.2), not substrate-cliff.

Fix: §2 major rewrite — replaced grep-based assessment with design-doc authority cite. C2 reclassified substrate-ready (same shape as C1). The earlier "(a) full carve-promotion vs (γ) stub" disposition is MOOT — there's no 4c canvas to author since the carrier already exists.

**Finding 3 — C3 readiness treated design sketch as landed substrate**:
Prior framing said "lens_application.dag exists" → "substrate-ready conditional on C1." Codex correct: Slice A landed (#88-#90 PR #2145) but Slice B (#91 per-lens LensEnforcement projection + violation routing) is pending per design §10 step 2.

Fix: §3 corrects scope. C3 cascade-gates on (a) T-LAS Slice B landing + (b) C1 parallelism lens BEHAVIORALLY COMPLETE. Both prerequisites named explicitly.

**Finding 4 — C3 scoped to opt-in parallelism worked example instead of shared lens-application surface lane**:
Prior framing treated #95 as separate carve. Per r3-structure.md:164: #95 is the "fourth worked example (design §4.4)" — a demonstration gate UNDER the T-Lens-Application-Surface lane. It's a worked-example demo, not a separate substrate carve.

Fix: §3 corrects scope alignment with r3-structure.md + design-lens-application-surface.md. #95 promotes as worked-example demo gate; substrate prerequisites (Slice B + C1) tracked in their respective lanes.

**Net audit revision**: all 3 carves substrate-ready (was: 2 ready + 1 cliff). No substrate-cliff in any carve. §0 + §4 + §5 + §6 updated to reflect.

* fix(audit): §3.1 C3 cascade — distinguish gate-level vs lane-level dependencies (codex BLOCKING)

codex inline BLOCKING @ docs/audit/r3-r4-carve-substrate-readiness-2026-05-09.md:112: prior cascade chain "C3 cascade-gates on parallelism lens BEHAVIORALLY COMPLETE" understated the lane-level dependency.

Per r3-structure.md:61: T-Lens-Application-Surface lane depends on T-Lens-Behavioral-Parity COMPLETE (all 4 in-R3 lenses: complexity #79 + cost #80 + parallelism #81 + effect_enum #82), not only C1.

Fix: §3.1 distinguishes:
- Lane-level (T-LAS Slice B substrate authoring complete): gates on full T-LBP COMPLETE.
- Gate-level (#95 specific demo): gates on parallelism-lens projection within Slice B + parallelism BEHAVIORALLY COMPLETE (C1).

Both dependencies named explicitly. The simplified "cascade-gates on Slice B + C1" framing was correct for #95-specific firing but understated the lane-level closure dependency.

* fix(audit): C3 §3.1 live-ledger reading + parent-doc on-main scope (codex BLOCKING round 2)

codex review on PR #2363 sha 32afcd3: 2 BLOCKING findings.

**BLOCKING #1 — non-live parent authorities**

Parent docs section listed `r3-pb0-velocity-walk-2026-05-09.md` as
authority but it's not on main (concurrent PR #2358). Codex's broader
"first two parent authority links absent" framing is a tree-visibility
false positive on r4-carve-out-routing.md + r3-program-plan.md (both
exist on main per `git ls-tree origin/main`), but the underlying
finding about authority-chain live-state grounding is valid.

Fix: split parent docs into "Parent docs (live state on main)" vs
"In-flight authorities" sections. On-main set: r4-carve-out-routing.md
+ r3-program-plan.md + r3-structure.md + design-effect-enumeration-
resource-threading.md + design-lens-application-surface.md (each
verified via git ls-tree on origin/main). In-flight: velocity-walk
(PR #2358) cited inline only for routing context — substrate state of
effects.dag + workflow_parallelism.rs is independently verifiable on
main without needing the velocity-walk authority.

**BLOCKING #2 — C3 imports PR/status claims instead of live state**

Prior §3.1 misidentified gate-number → carrier mapping:
- Cited "Slice A landed (#88-#90)" + "Slice B (#91 per-lens
  LensEnforcement projection + violation routing) NOT yet landed"
- Live ledger on main says #90 = lens_enforcement_carrier_landed
  (CONSUMER_LANDED Slice A; parametric carrier landed; per-lens
  data instances pending Slice B per #90 Pass condition); #91 =
  enforce_violation_routing_landed (DECLARED; substrate routing
  surface landed PR #2145; CONSUMER_LANDED requires fold-pass
  consumer per design §10 step 2 — deferred to Slice B)

Fix: replaced grep-based gate-status framing with live-ledger
reading table citing exact §1.8 row content from r3-program-plan.md
on main. What's actually pending for Slice B (per #90 + #91 Pass
conditions on main): per-lens data instances of LensEnforcement
co-located with each lens (parallelism specifically for #95) +
fold-pass consumer for #91 violation routing.

§3.2 Cascade-gating chain rewritten as 4-step ordering with substrate
prerequisite (carrier landing before #95) made explicit per codex
BLOCKING ratification.

* fix(audit): §0 C3 + §0 prerequisites — live-state mapping cascade (codex BLOCKING round 3)

codex review on PR #2363 sha 54e4baf: BLOCKING — "Audit still imports
non-live PR/status claims as live authorities → replace the missing
parent docs with live repo authorities and rebase C3 on the current
T-LAS design/readiness docs with carrier landing as a prerequisite."

§3.1 live-ledger table (added at sha 54e4baf) correctly mapped gates
#88/#89/#90/#91 to live blob in src/v3/std/lens_application.dag, but
§0 summary table row C3 + §0 prerequisites bullet still used the
prior PR-status framing that misidentified #91 as
"per-lens LensEnforcement projection + violation routing" — that's
actually #90's Pass condition Slice B requirement (parametric
carrier landed Slice A; per-lens instances pending Slice B).

Fix: cascade §3.1's live-state mapping into §0:
- §0 row C3: cite live blob (`src/v3/std/lens_application.dag`,
  blob `968aa84a` per git ls-tree origin/main) + correct gate-to-Slice
  mapping + Slice B prereqs split (a) per-lens instance per #90 Pass
  condition; (b) fold-pass consumer for #91 violation routing per
  locked design §10 step 2
- §0 prerequisites bullet: same 3-prong split (a)+(b)+(c)
  parallelism BEHAVIORALLY COMPLETE; cross-ref to §3.1 table for
  live-state authority

…r3-program-plan + r4-carve-out-routing (#2364)

* docs(r3): Task 12 carve-promotion amendment — Cluster F sequencing + r3-program-plan + r4-carve-out-routing

Per Director (a) ratification at gunbc#846 #issuecomment-4412380947 (carve-promotion-IN-R3 + 4-phase Cluster F sequencing) + greenlight at #issuecomment-4412392036 ("PM authors carve-promotion amendment PR").

Three workstreams bundled:

**1. Cluster F sequencing plan** (NEW): `docs/audit/r3-cluster-f-sequencing-plan-2026-05-09.md` — 4-phase plan (F-α / F-β.1 / F-β.2 / F-γ) covering #81/#82/#95 carve-promotion + #83 scope-narrowing dissolution. Lane-Mgr partition (Substrate Mgr owns F-α/F-β; Verification Mgr owns F-γ #95 demo). F-α + F-β.1 parallel-dispatchable; F-β.2 cascade-gates on canvas ratification; F-γ cascade-gates on F-α + T-LAS Slice B.

**2. r3-program-plan.md amendments**:
- §1.5 R4-carved-rows paragraph: marked DISSOLVED with citation to Director ratifications + operator framing; gates #81/#82/#95 reclassified R4-carved → R3-load-bearing within Cluster F; gate #83 scope-narrowing dissolved.
- §1.8 row #81: R4-CARVED (C1) → R3-LOAD-BEARING (Cluster F F-α; substrate-ready walker port).
- §1.8 row #82: R4-CARVED (C2) → R3-LOAD-BEARING (atomic migration per locked design §3.2 + §6.2; Operation carrier already exists at services.dag:122; F-β.1 + F-β.2).
- §1.8 row #83: NARROWED scope → full scope (fires for all 4 in-R3 lenses; F-γ).
- §1.8 row #95: R4-CARVED (C1 cascade) → R3-LOAD-BEARING (worked-example demo cascade-gated on F-α + T-LAS Slice B; F-γ).

**3. r4-carve-out-routing.md amendments**:
- C1 entry: marked DISSOLVED 2026-05-09 (carve-promoted to R3 Cluster F-α).
- C2 entry: marked DISSOLVED 2026-05-09 (carve-promoted to R3 Cluster F-β; locked design says no new substrate needed).
- C3 entry: marked DISSOLVED 2026-05-09 (scope-narrowing dissolved alongside C1/C2 promotion; #83 fires for all 4 lenses).

Cites PR #2363 substrate-readiness audit findings inline. R3 close target: 96 R3-load-bearing gates green (no carves; only #11 canvas-deferral subtracted).

* fix(r3): F-β.1 — substrate canvas surfaces 4c shape question (open per Director (a) framing)

Director ratification at gunbc#846 #issuecomment-4412380947 + reaffirmed at #issuecomment-4412402891: "(a) full carve-promotion including 4c new P1 substrate; Substrate Mgr authors r3-substrate-effect-set-pinning-canvas-2026-05-09.md under standing authority; Director ratifies surfaced shape questions."

My prior Task 12 framing (sha 7cfd28f) presupposed "no new substrate per design §6.2" — too prescriptive vs Director's strict (a) framing of "4c new P1 substrate canvas authoring."

Fix: F-β.1 scope re-framed as substrate-shape canvas (open question), not migration-shape canvas (presupposed answer):
- Cluster F plan §1.2: canvas surfaces 4c shape question; reconciles locked-design §3.2 ("Operation carrier exists; no new top-level carrier required") against Director's "4c new P1 substrate" framing; Director ratifies disposition.
- Cluster F plan §1.3 F-β.2: scope contingent on F-β.1 ratified shape (atomic migration OR new substrate, depending on canvas outcome).
- §0 executive summary table updated: F-β.1 is "shape-question canvas; Director ratifies disposition."
- r3-program-plan.md §1.8 row #82: updated to reflect canvas-then-implementation sequence with both shape paths cited.

Per Director's explicit "Substrate Mgr surfaces shape questions; Director ratifies" pattern (T-WAD Slice 2 precedent): the canvas IS the right shape; let it surface the question rather than PM presupposing the answer in the audit.

* fix(r3): Cluster F collapse to 3-phase (F-α / F-β / F-γ) per Director (a-corrected)

Director (a-corrected) ratification at gunbc#846 #issuecomment-4412433924: PM round-1 audit fix at sha 530376d is structurally correct — locked design `design-effect-enumeration-resource-threading.md` §3.2 + §6.2 says Operation carrier already exists at services.dag:122; no new top-level carrier required. (a-as-stated) would author parallel 4c carrier — direct violation of feedback_parallel_representation_debt.

Fix: Cluster F collapses from 4-phase (F-α / F-β.1 canvas / F-β.2 implementation / F-γ) to 3-phase (F-α / F-β atomic migration / F-γ).

Updates:
- Cluster F sequencing plan §0 table: F-β.1 + F-β.2 → F-β (atomic migration; substrate-ready; same shape as F-α; no canvas needed)
- §1.2 + §1.3 (canvas + implementation) collapsed to single §1.2 F-β atomic migration with locked-design citations
- §1.4 F-γ renumbered to §1.3
- §2 cross-Mgr coordination table simplified
- §3 velocity-to-zero contribution updated
- §4 sequencing within R3 window: F-α + F-β parallel-dispatchable weeks 1-3
- §5 spawn-authority queue: single F-β worker (no canvas-author needed)
- §6 dispatch readiness checklist simplified
- r3-program-plan.md §1.8 row #82: removed canvas-tier framing; cite (a-corrected) ratification + atomic migration shape
- r3-program-plan.md §1.8 row #83: cross-ref §1.4 → §1.3

Velocity-to-zero contribution: 6-10 → 5-9 bulk events (canvas event drops; F-β single-phase port).

* fix(audit): F-γ split into F-γ.1 (#95) + F-γ.2 (#83) — different cascade prerequisites (codex BLOCKING)

codex inline BLOCKING @ docs/audit/r3-cluster-f-sequencing-plan-2026-05-09.md:22: prior single-phase F-γ collapsed two gates with different prerequisite sets — only #95 cascade prerequisites named (post-F-α + T-LAS Slice B), allowing #83 register to be scheduled before cost (#79) / effect_enum (#82) completion. INVARIANTS P2 violation.

Fix: F-γ split into F-γ.1 + F-γ.2 with distinct cascade prerequisites:
- F-γ.1 (#95 demo): cascade post-F-α (parallelism BEHAVIORALLY COMPLETE) + T-LAS Slice B (per-lens LensEnforcement projection)
- F-γ.2 (#83 register full-scope): cascade post-ALL 4 lenses BEHAVIORALLY COMPLETE — F-α (#81 parallelism) + F-β (#82 effect_enum) + #79 (complexity, T-LBP existing) + #80 (cost, T-LBP existing)

§0 table updated; §1.3 split into §1.3.1 + §1.3.2 with full prerequisite enumeration. One canonical close predicate per phase per INVARIANTS P2.

* fix(r3): Cluster F revert to 5-phase per Director c#4412475559 — F-β.1 stays as migration-shape canvas

Director revised (a-corrected) at gunbc#846 #issuecomment-4412475559: F-β.1 stays as separate migration-shape ratification canvas phase (NOT collapsed). Migration shape decisions (Operation field reads / walker rewire surface / test-consumer breaking changes) warrant early Director-tier ratification per feedback_construction_over_ratchets.

Pattern named: substrate-shape canvases for novel substrate; migration-shape canvases for non-trivial ports. Both surface decisions upfront.

Updates:
- §0 sequencing table: F-β collapse undone — F-β.1 (canvas) + F-β.2 (implementation) restored
- §1.2 + §1.3: split into F-β.1 migration-shape canvas + F-β.2 atomic-migration implementation (with locked-design citations preserved — no new substrate; Operation carrier authoritative)
- §1.4 F-γ split (F-γ.1 + F-γ.2 per prior codex BLOCKING) renumbered from §1.3
- §2 cross-Mgr table: F-β.1 + F-β.2 rows
- §3 velocity contribution updated
- §4 sequencing within R3 window: F-β.1 weeks 1-2 (parallel F-α); F-β.2 weeks 2-4 (post-canvas)
- §5 spawn-queue: F-β.1 canvas-author (standing authority) + F-β.2 worker (post-canvas)
- §6 dispatch readiness checklist: 2 F-β items
- r3-program-plan.md row #82: cite full ratification cascade (#4412380947 → #4412433924 → #4412475559); reflect F-β.1 + F-β.2 sub-phase split
- r3-program-plan.md row #83: §1.3 cross-ref → §1.4.2

Final 5-phase Cluster F: F-α / F-β.1 / F-β.2 / F-γ.1 / F-γ.2. Velocity-to-zero: 5-9 bulk events.

* fix(r3): r3-program-plan post-carve-promotion reconciliation (codex BLOCKING)

codex inline BLOCKING @ docs/r3-program-plan.md:92: line 92 sets R3
close target at 96 R3-load-bearing while adjacent §1 Pass-surface
text still says 94, creating two authorities for the R3 acceptance
count (P2 single-authority violation).

Root cause: PR #2364 originally amended only the carve dissolution
paragraph (line 92) without reconciling parallel-authority references
elsewhere in the doc. The 94/R4-carved framing predates 2026-05-09
carve-promotion and persists at 8 other locations.

Fix-forward: full carve-promotion-aware reconciliation across:
- §1 (top "R3 close" definition, line 8) — replace stale "97/CARVED to R4 / option (b)" framing with carve-promotion-aware "97 enumerated / 96 R3-load-bearing / all 4 lenses R3-load-bearing within Cluster F"
- §1.5 Total (line 84) — replace "94 R3 thesis-load-bearing / R4-carved" with canonical block: 97 enumerated / 0 carves dissolved / 96 R3-load-bearing (post #11 canvas-deferral subtraction)
- §1 Pass-surface bullets (lines 95, 98) — 94 → 96
- §1.7 R3 close criteria (line 123) — minus #81/#82/#95 carved → minus #11 canvas-deferred
- §1.6 lane gate row T-Lens-Behavioral-Parity (line 170) — all 4 lenses R3-load-bearing
- §1.8 row #11 (line 218) — restore (a)-disposition CANVAS-DEFERRED amendment from PR #2361 (cleaning fabricated 473b99fb hash placeholder)
- §1.8 row #73 status (line 274) — all 4 lenses post-promotion framing
- §1.8 epilogue (line 303) — 94 → 96
- §5/6 R3 close (line 590) — 94 → 96
- §10.3 Q-LBP-R3-Closeability (line 1023) — append 2026-05-09 AMENDED note dissolving option (b) carve-narrowing

Also removes fabricated `473b99fb...` placeholder hash from line 92
(was inserted as decision-id placeholder in earlier amendment;
git log shows no such commit; replaced with descriptive cite).

Single canonical authority: 97 enumerated → 96 R3-load-bearing
(only #11 canvas-deferred; 0 R4 carves at R3 close per Director
ratification 2026-05-09 c#4412330468). Cited consistently across
§1 / §1.5 / §1.6 / §1.7 / §1.8 / §3 / §5 / §10.3.

Note on PR #2361 overlap: PR #2361's §1.5 canonicalization block
(commit 2e782f2) already lands the same §1.5 fix. This PR makes
PR #2364 self-consistent independent of merge ordering — squash-merge
will resolve overlapping content cleanly (whichever PR merges
second's diff for those lines is empty).

* fix(audit): Cluster F §2/§3/§4/§5/§6 cascade — F-γ split + checklist verb

codex review on PR #2364 sha 7cfd28f: 1 BLOCKING + 1 non-blocking
Cluster F sequencing plan finding.

**BLOCKING fix already landed**: F-γ split → F-γ.1 (#95) + F-γ.2 (#83)
at sha a763ab3 (codex prior BLOCKING on the same gate-prerequisite
collapse). §0 sequencing table + §1.4 phase scopes already split.

**Cascade gap**: §2 cross-Mgr table + §3 velocity bullets + §4 R3-window
sequencing table + §5 spawn-queue + §6 dispatch checklist still cited
single F-γ phase. Now reconciled — every reference to F-γ now uses
F-γ.1 or F-γ.2 with each gate's distinct prerequisite set surfaced.

**Non-blocking fix**: §6 dispatch checklist line 198 said
"`r4-carve-out-routing.md` C1/C2/C3 entries removed (in this Task 12
PR)" but the PR amends to dissolved-status (not removed). Updated
verb to match actual PR content.

…2744 §1 (#2750)

* docs(r3): T-WAD FULL R3 §1.8 ledger sync — +6 gates (#98–#103) per PR #2744 §1

**Authority**: PM scoping doc PR #2744 §1 (T-WAD FULL R3 elevation per operator
directive 2026-05-12 + Director ratification msg_5cbdad24 + msg_f9fd669e + (b)
ledger-sync disposition msg_2a68a4b5 — follow-up sync PR pattern).

**Sync disposition rationale** (per Director msg_2a68a4b5): option (a) bundles too
much into PR #2744 mid-review; (c) bakes parallel-authority into scope doc as
"temporary" PROPOSED state which calcifies. (b) is operationally clean if sync
PR queues for atomic-merge-sequencing alongside PR #2744 — gap window bounded
to merge-clock seconds.

**6 new §1.8 gate rows** (all T-Workflow-As-Data, NEW 2026-05-12):

- **#98** `ci_yml_hand_authority_dissolved` (state-check) — hand-authority NOT
  file-deletion; (a) absent / (b) emission-artifact / (c) thin-shim per
  briansrls BLOCKING #PR2744 fix
- **#99** `emission_target_open_enum_landed` (substrate-shape) — EmissionTarget
  sum-type per (c-refined) shape at PR #2749 §7
- **#100** `project_github_actions_landed` (substrate-shape) — projection
  function declaration in gunbc namespace; consumes extdeps.github.actions.Workflow
  as codomain + CIWorkflowDag (PR #2736 carrier) as input domain
- **#101** `test_cost_dimension_landed` (substrate-shape) — Cost dimension on
  TEST NODES (distinct from existing compiler-internal cost gates
  #37/#39/#40/#70/#80 which are about SymbolicCost as the compiler's cost lens;
  this gate is about Cost-as-Dimension applied to test nodes so slow-test
  ratchet derives structurally)
- **#102** `slow_test_exemptions_dissolved` (state-check) — scripts/slow-test-
  exemptions.txt deleted; sibling of #101 per kernel-modeling discipline split
- **#103** `ci_uses_affected_set_selection` (state-check) — BinaryShim emitter
  consumes affected-set lens output from PR #2713; Layer 2 path-regex `if:`
  gates removed; cross-tier co-owned with clever-tern-670 Slice 7

**Count updates** (was 97 enumerated / 96 R3-load-bearing; now 103/102):

- §1.5 total enumeration: 97 → 103
- §1.5 R3-load-bearing arithmetic: 96 → 102 (= 103 - 1 canvas-deferred {#11})
- §1.5 composition tally: T-Workflow-As-Data 4 → 10 (+6 NEW)
- §1.5 prose: R3 close target 96 → 102
- §1.5 R4-carved-dissolved framing: target 96 → 102
- §1.7 status-taxonomy lead: 96 → 102 R3-load-bearing
- §1.8 standing-program note: 96 → 102 load-bearing
- §0 R3 close criteria: 97/96 → 103/102
- §1 plan-declared count: 97 → 103
- §1.6 acceptance criteria: 97/96 → 103/102
- §1.8 §1.8 single-canonical-view: 97 → 103
- §1.8 row #11 canvas-deferral arithmetic: 97 → 103
- §Q1 table: 97 → 103 + history pointer

**Sequencing discipline** (per Director msg_2a68a4b5):
1. This sync PR sits ready-to-merge until PR #2744 lands
2. As soon as PR #2744 squash-merges, fire this sync PR squash-merge immediately
3. Gap window: bounded to merge-clock seconds (atomic-as-possible without bundle)
4. If reviewer delay accumulates here, fold into PR #2744 retroactively (option (a)
   escalation path)

**Cost-dim distinction note** (per Director verification flag): existing gates
#37/#39/#40/#70/#80 are about compiler-internal SymbolicCost (cost lens reading
target programs). #101 is structurally distinct — Cost dimension on TEST NODES
for slow-test ratchet derivation. Not a duplicate.

**§1.9 acceptance-aggregator pilot row** (`t_ci_wad_full_r3_close`): remains in
PR #2744 §9 with gate-name references per `feedback_no_snapshot_integers_in_briefs`
discipline. No row added to this sync PR per Director msg_2a68a4b5 ("EITHER PR
#2744 §9 OR sync PR — your call; either works").

* docs(r3): cross-doc authority sync — add 6 NEW T-WAD gates to r3-structure.md §Acceptance

Per codex BLOCKING review on PR #2750 (2026-05-12T07:34:59Z): scope doc lines
13 and 84 claim r3-structure.md was "updated in this PR" + reference 103-gate
total per r3-structure.md §Acceptance, but the PR only changed r3-program-plan.md
— r3-structure.md still had no #98–#103 rows. That violated INVARIANTS.md P2 /
modeling-discipline.md Practice 5 (single-authority metadata) — the closure
ledger became internally inconsistent at the canonical-source level.

Fix: add the 6 NEW gate bullets to r3-structure.md §Acceptance T-Workflow-As-Data
section (after `ci_workflow_modeled_as_dag`), mirroring r3-program-plan.md §1.8
rows #98–#103. Each bullet carries the full Pass-condition body (single-source
authority for Pass conditions per the r3-program-plan.md convention).

Now both docs land the same gate set atomically in this PR:
- r3-program-plan.md §1.8 rows #98–#103 (commit ef9a140, prior)
- r3-structure.md §Acceptance T-WAD bullets (this commit) — matching content

The "Documentation Describes Live State" rule + single-authority discipline
restored.

* docs(r3): briansrls BLOCKING fix — propagate 103/102 counts through full plan

Per briansrls BLOCKING inline review on PR #2750 at line 84 (2026-05-12T07:50:26Z):
"The new 103/102 canonical count is not propagated through the full plan,
leaving later close criteria at 96/97 and creating competing R3 thresholds
(INVARIANTS P2 single authority)."

Three stale references found in re-grep + fixed:

- Line 114 (§1.7 two-Pass-surfaces context): "**96** R3-load-bearing gates
  green" → "**102** R3-load-bearing gates green" (post-carve-promotion +
  T-WAD FULL R3 elevation)
- Line 623 (§5.2 R3 close definition): "**96** load-bearing post-carve-
  promotion" → "**102** load-bearing post-carve-promotion + T-WAD FULL R3
  elevation"
- Line 1001 (§10 dependency-graph mirror): "lane TestClaim gates (97 total)"
  → "lane TestClaim gates (103 total; 102 R3-load-bearing post-T-WAD-FULL-
  R3-elevation 2026-05-12)"

Initial sync (commit ef9a140) updated §0 + §1.5 + §1.6 + §1.7 + §1.8 + Q1
table; this commit completes propagation through §1.7 two-Pass-surfaces /
§5.2 R3 close definition / §10 dependency-graph mirror.

Single-authority discipline (INVARIANTS P2) now consistently asserts 103/102
across the full plan; no competing R3 thresholds remain.

* docs(r3): InlineGunbc DESIGN-ONLY alignment — cross-doc consistency with PR #2744 openai-pro BLOCKING fix

Per openai-pro BLOCKING fix on PR #2744 (commit e43aba3): WI-1 / WI-2 briefs
+ scope doc §2 type sketch all align on InlineGunbc as DESIGN-ONLY (NOT in
initial enum, lands when runtime consumer exists). The §1.8 gate bodies in
r3-program-plan.md row #99 + r3-structure.md §Acceptance bullet for
emission_target_open_enum_landed were stale relative to that alignment.

Fix in this sync PR:
- r3-program-plan.md §1.8 row #99: "(YamlStatic | BinaryShim | PythonShim |
  InlineGunbc | ...)" → "3 initial arms (...)" + InlineGunbc DESIGN-ONLY note
  with PR #2746 §5.4 + openai-pro BLOCKING cross-references
- r3-structure.md §Acceptance T-WAD bullet for emission_target_open_enum_landed:
  same change pattern

Single-authority across:
- PR #2744 scope doc §0 / §1 gate row / §2 type sketch
- PR #2744 WI-1 brief DESIGN-ONLY discipline
- PR #2744 WI-2 brief Output / DO-DON'T / Acceptance gates
- PR #2750 (this PR) §1.8 ledger row + §Acceptance archive
- PR #2746 §5.4 canonical DESIGN-ONLY framing

* docs(r3): T-WAD ledger sync — lane-definition gate lists pointer-only + scope-doc cross-ref qualifier (codex BLOCKING + non-blocking on PR #2750)

Two findings from codex review #10042 on commit 0c08f77 (T-WAD ledger
sync PR head):

BLOCKING — "T-WAD ledger sync updated the Acceptance archive but skipped
the lane-definition gate lists → update those T-Workflow-As-Data gate
lists to include #98–#103 or make them pointer-only."

The PR #2750 cascade landed the 6 NEW T-WAD FULL gates (#98–#103) in:
- r3-structure.md §Acceptance T-Workflow-As-Data bullets (lines 172-177)
- r3-program-plan.md §1.8 ledger rows
- r3-program-plan.md count propagation (§0/§1.5/§1.6/§1.7/§5.2/§10/§Q1)

But the cascade missed two lane-DEFINITION gate lists in r3-structure.md
that ALSO enumerate T-WAD closure gates:
- Line 41 (numbered lane list, T-WAD entry)
- Line 222 (T-WAD row in §"Lane structure" table)

Both listed only the original 4 pre-FULL gates
(workflow_substrate_carriers_landed / timing_lens_carrier_landed /
ci_workflow_modeled_as_dag /
shared_external_attachment_pattern_documented). Reviewers reading
either list would not see the 6 NEW gates — INVARIANTS P2
single-authority gap.

Fix: convert both lane-definition lists to pointer-only references back
to §Acceptance T-WAD as the canonical gate list. Rationale: §Acceptance
is the authority anchor (per INVARIANTS P2 + sister r3-program-plan.md
§1.8); duplication in lane-definition lists would re-introduce drift
the cascade is closing. Also augmented both lane-definition entries
with FULL R3-close elevation 2026-05-12 framing + multi-Mgr ownership
(Substrate Mgr Slices 4-5/8 + Verification Mgr Slice 7 affected-set +
Debt-Paydown Mgr Slice 6 sub-component).

Non-blocking — "Line 172 cites
docs/r3-t-workflow-as-data-full-r3-close-scope.md, but git
ls-tree origin/main returned no blob → replace with existing receipt
or land the scope doc."

The scope doc exists on PR #2744's branch (in flight) but not on
origin/main yet. Codex correctly notes the dangling cross-reference
against current main. Fix: add explicit "(scope doc landing via
in-flight PR #2744)" qualifier so future readers know the citation
is forward-referencing a known in-flight PR rather than a typo or
missing doc.

* docs(r3): T-WAD ledger sync — remove dangling file refs (briansrls BLOCKING + codex INVARIANTS P2/P5 escalation on PR #2750)

briansrls inline BLOCKING at r3-structure.md:172 (2026-05-12T09:28:04Z)
escalated the prior non-blocking scope-doc citation issue to BLOCKING:

  "The new gate cites docs/r3-t-workflow-as-data-full-r3-close-scope.md
   section 1, but git ls-tree origin/main produced no blob and the
   reconstructed PR-head test returned 1, so the cited T-WAD scope
   authority is absent (INVARIANTS P2/P5)."

The earlier qualifier fix ("scope doc landing via in-flight PR #2744")
acknowledged the dangling reference but didn't resolve the structural
P2/P5 violation — the gate description still CITED an authority that
doesn't exist on origin/main, which is the merge target.

Audit: grepped both docs for refs to files that don't exist on
origin/main:
- docs/r3-structure.md:172 — `docs/r3-t-workflow-as-data-full-r3-close-scope.md` (PR #2744)
- docs/r3-program-plan.md:326 — `docs/briefs/r3-t-wad-full-r3-cidag-scaffold-worker.md` (PR #2744)

Fix: replace both file-path references with PR-number anchors. PR
numbers are stable references; file paths become valid only post-merge.
Gate descriptions are self-contained without the cross-references
(the (a)/(b)/(c) enumeration + supporting framing already conveys the
gate's substance).

- r3-structure.md:172: "per `docs/r3-t-workflow-as-data-full-r3-close-scope.md` §1 — scope doc landing via in-flight PR #2744" → "in-flight scope authority at PR #2744 §1"
- r3-program-plan.md:326: "WI-2 implementation: `docs/briefs/r3-t-wad-full-r3-cidag-scaffold-worker.md`" → "WI-2 implementation: in-flight via PR #2744 (brief lands with the scope-doc)"

Both gates retain full substantive content; only the file-path crutches
are removed. When PR #2744 merges and the files exist on main, future
authors may re-add file refs cleanly — but the gate descriptions never
needed them as load-bearing authority.

* docs(r3): T-WAD ledger sync — EmissionTarget → WorkflowRuntime rename cascade (warm-wolf-698 PR #2749 commit 575eb7e; SELF_HOSTING.md:609 name collision)

Cascade sister-PR rename: PR #2744 branch carries the scope-doc + brief
renames in commit 70a49ac; this commit carries the ledger / structure
gate-ID renames.

warm-wolf-698 surfaced a DECISIVE name-collision finding at PR #2749:666
/ :672 (briansrls operator BLOCKING 2026-05-12T09:26:49Z): the canvas
EmissionTarget sum-type collides with the canonical Shape-A carrier
declared at `src/v3/SELF_HOSTING.md:609`:

  type EmissionTarget {
    language: LanguageSpec       // what's valid (required)
    rendering: RenderingSpec?    // how to format (optional)
  }

This is the SELF_HOSTING.md emitter-composition authority — INVARIANTS
P2 violation. warm-wolf-698 pushed rename to WorkflowRuntime in PR
#2749 commit 575eb7e (48 occurrences). All OTHER ratified elements
stand per feedback_pre_compaction_framings_self_supersede.

This commit cascades the rename through PR #2750 branch:

- docs/r3-program-plan.md §1.8 row #99:
  gate ID emission_target_open_enum_landed → workflow_runtime_open_enum_landed
  (also EmissionTarget references in row description)

…ve-2 dispatch (#2787)

* docs(audit): gpt-5-5-pro cross-review findings — 8 novel items for Wave-2 dispatch

Captures 8 NOVEL findings from 2 independent gpt-5-5-pro exploratory analyses
against main@6897445 + main@1de959e. Already-tracked items (~17 across the 2
reviews) owned by existing ROADMAP rows; this doc enumerates novel only.

**Tier 1 — Real correctness bugs (Director-tier signals)**:
- F1: complexity.dag SameArgumentCall returns successful UnknownCost summary
  contrary to own design note + cost.dag fail-closed (may invalidate #79 PASSING)
- F2: duplicate field/variant labels accepted; consumers use first-match
  (sibling fail-closed exists for record-literals but not type-decls/variants)
- F3: Certainty non-isomorphism between dsl/std/primitives.dag (4 variants) and
  src/v3/lenses/complexity.dag (2 variants) — lossy projection (may invalidate
  #79/#80 PASSING)

**Tier 2 — Structural defense**:
- F4: post_emit_verifier unbounded Command::output() — P4 violation

**Tier 3 — Compositional modeling**:
- F5: CompositionVerdict as first-breaker Monoid
- F6: build.rs bootstrap priority list as Rust authority for .dag-declarable facts
- F7: GH Actions Job.needs as List<String> instead of List<JobRef>

**Tier 4 — Small Rust string lists**:
- F8: L5_REQUIRED_TOOLCHAINS hardcoded

Routing: F1/F2/F3/F5/F6/F7 → Substrate Mgr (warm-wolf-698) Wave-2;
F4/F8 → Verification Mgr (clever-tern-670) Wave-2.

Director-tier signal for F1+F3 (gate #79/#80 PASSING validity).

Convergence between the two reviews on tracked items is itself structural-fact
signal per feedback_independent_cross_validation.md.

* docs(audit): fix codex #10376 REQUEST_CHANGES — ungrounded memory citation + F2 scope framing

Two codex BLOCKING findings on PR #2787:

1. Lines 9 + 212 cited `feedback_independent_cross_validation.md` which is a
   PM-private memory not in the repo. P1/P2 violation: ungrounded citation.
   Replaced with plain-prose statement of the convergence-confidence
   principle (no claim of repo authority).

2. F2 "novel only" banner packaged the genuinely-new extension
   (type-decl / variant-payload / sum-variant labels) together with
   already-tracked record-literal duplicate handling (ROADMAP:514).
   Added explicit scope-discrimination block at top of F2 separating
   ALREADY-TRACKED (record-literal, reference-only) from GENUINELY-NOVEL
   (three distinct sites with no fail-closed check).

Also tightened the methodology note (line 212 region) to frame
convergence as analytic confidence, not authority, and to emphasize
per-citation grep-verify before work-item absorption.

* docs(audit): retract F6 — build.rs priority list already tracked at deferrals doc

Operator (briansrls) + codex BLOCKING on PR #2787 — two-reviewer
convergence. F6 (build.rs bootstrap priority list) is NOT novel; it's
already owned by docs/history/roadmap-active-deferrals.md:172 with
explicit dissolution trigger + yellow-flag threshold.

Routing F6 as a Wave-2 novel finding would create dual dispatch
authority (deferrals doc + audit doc) — INVARIANTS P2/P5 violation.

Fixes:
1. F6 section reframed as RETRACTED FROM NOVEL LIST; cites deferrals
   doc as single authority; preserves source convergence (Review A #4
   + Review B #8) as audit-trail without adding dispatch scope
2. Lane-routing table F6 row marked RETRACTED (not Wave-2 dispatch)
3. Status disposition table F6 entry corrected — prior "Partly
   tracked... specific bootstrap priority dissolution not named"
   classification was wrong; the dissolution IS named in the
   deferrals doc, I missed that doc when reconciling against
   ROADMAP.md only
