Director (α) amendment-PR authorized at #828 #issuecomment-4404398425 post-codex BLOCKING at PR #2222 c#4404360699.

Change

regen_bootstrap_emit.rs cites replaced with scripts/regen_runtime_mirrors.py (the substrate→Rust runtime-mirror generator). Inline notes mark amendment for future-reader audit trail.

D1 (b) ratification UNCHANGED

Only authority-path cites corrected. Carrier slice path #2223 already updated independently.

Docs-only +7/-7. Standing-authority discipline applies.

…nt worker brief

Authored for gunbc#1958 Substrate-owned bridge slice. Targets audit-row #2
(kernel Bool patch BOOL_TYPES_FILE) + row #6 (pipeline authority
PIPELINE_AUTHORITY_FILE) per r3-program-plan.md §5 line 353 scope-narrowing.
Sibling #1959 closed as already-retired by PR #1272.

Surfaces 3 carrier-shape options (α RestResponseProjection variant-tag /
β Declaration variant_projection_metadata / γ free-standing CoproductProjection)
for Director ratification before worker brief authoring. Mgr-tier recommendation
= γ (DeclarationRef-keyed, avoids tag-string-as-identity bridge).

…on anchor

Director calibration (gunbc#2079 #issuecomment-...):
1. Promote ratchet-test cross-Mgr handoff from conditional Acceptance #4
   to upfront same-slice BLOCKING prerequisite gate (per
   feedback_same_slice_dissolution_discipline).
2. Replace `r3-program-plan.md:353` line-cite with `§5 Y4 scope-clarification`
   section anchor (per feedback_section_anchors_over_line_numbers).

Code-line anchors in bootstrap.rs left as-is (anchor sites worker navigates to).

…er discipline

Address BLOCKING inline review at line 46: bridge_source_span_file_participation_retired
is an Open umbrella whose green predicate is "no production code path consults
SourceSpan.file" per r3-structure.md:115. Partial retirement was explicitly
rejected 2026-04-29 (Director acceptance #1130 / dispatch #1139).

Changes:
- Add Ledger-discipline preamble: umbrella row stays Open; receipt updates
  audit-packet enumeration, NOT bridge_ledger.dag.
- Acceptance #3 reframed: do NOT mutate bridge_ledger.dag; mark rows #2 + #6
  retired in the audit packet only.
- Authority anchor updated: status=Open (not Proposed); add r3-structure.md:115
  + bridge_ledger.dag:125-129 line refs.
- Cross-Mgr section reframed: umbrella ratchet cannot flip on this PR alone;
  Verification's ledger-zero audit progress field is post-merge tracking,
  not a same-slice pre-merge blocker. Reconciles with BLOCKING finding
  (Director calibration #1 assumed umbrella ratchet could flip on partial
  retirement, which r3-structure.md:115 forbids).

Director ratification of option γ at gunbc#828 #issuecomment-4394369848.
Free-standing CoproductProjection carrier in src/v3/std/, DeclarationRef-keyed,
typed WireTagValue leaf, 4 same-slice acceptance gates.

Surfaces 3 substrate observations for STOP-and-PING (DeclarationRef String
alias; FieldRef does-not-exist-at-HEAD; tag_field String asymmetry) — worker
must escalate, not silently work around. PB Mgr cross-Mgr ping at carrier
landing (heads-up, not blocker).

…gr contradiction

openai-pro REQUEST_CHANGES at PR #2079 #issuecomment-... flagged Acceptance #4
("ratchet test passes ... confirmed-present at HEAD before merge") contradicting
the reframed Cross-Mgr section ("No same-slice ratchet-test gate applies; post-merge
tracking only"). Both said different things about whether the umbrella ratchet
is a pre-merge blocker.

Resolution: Acceptance #4 reframed to explicitly state "No umbrella-ratchet
pre-merge gate" — worker does NOT wait for Verification ratchet authoring;
acceptance for this slice is the audit-packet receipt update in #3. Cross-Mgr
handoff also updated to remove "ratchet authoring" from Verification's same-slice
duties.

…-and-PING items

Director pre-ratified dispositions at gunbc#828 #issuecomment-4394416049:
1. DeclarationRef alias: accept (b) + debt note (re-escalate only on same-slice break)
2. FieldRef: grep-decide between InputFieldRef-as-specialization vs rename
3. tag_field String asymmetry: typed introduction + debt note for migration

Worker proceeds without re-pinging unless evidence forces escalation. STOP-criteria
section narrowed accordingly.

Director ratification at gunbc#828 #issuecomment-4394427814 + proposal merge
at PR #2096 (commit fec8692): src/v3/std/substrate.dag::Dag IS the reflected
program; no new substrate carrier required. ReflectedProgram<T> rejected.

Gate A patches:
1. r3-program-plan.md §10.3: new Q-Reification row marked RATIFIED with PR #2096
   merge link + Gate A receipt scope (this PR + #1960 closed-as-non-addition).
2. r3-v-pattern-a-tc1-v1-worker.md: 3 sites — status header (Q-Reification
   CLEARED, Branch B η non-vacuity remains), worker-pin gate, E6-G1.a/E3
   producer dependency. Replaces ReflectedProgram<T> with consumer-wiring
   nuance: lens fold consumes Dag via .dag body authority through Evaluator.
3. r3-pr-e6-g1a-option3-static-lens-worker.md: 2 sites — same nuance: deferred
   work is consumer-wiring, NOT a separate carrier.
4. r3-pr-e8-w1-producer-contract-test-plan-worker.md: 1 site — fold-over-Dag
   reframe.

Receipt of pass-by-construction: this PR adds NO new .dag declaration to
src/v3/std/. The ratification is structurally a non-addition (Option A
correctness proof per same-slice dissolution discipline).

…r for tag_field asymmetry

openai-pro REQUEST_CHANGES at gunbc#2079: 2 BLOCKING findings (P2 single-authority
+ P5 dissolution trigger).

Fixes:
1. Delete docs/briefs/r3-substrate-s5-variant-aware-projection-carrier-canvas.md
   (superseded by the γ-ratified worker brief in same PR; would otherwise leave
   two current-looking S5 status authorities post-merge — one saying ratification
   pending, one saying γ ratified).
2. Substrate observation #3 (tag_field String/FieldRef asymmetry) now carries a
   binding named dissolution trigger: when FieldRef exists as top-level carrier
   AND InputFieldRef is classified, migrate InternallyTaggedObject.tag_field via
   follow-on Substrate hygiene PR. Worker MUST add debt-paydown row to authoritative
   debt ledger before merging carrier-introduction PR.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
cursor review at gunbc#2079 #issuecomment-... flagged C-1 as mis-keyed:
INVARIANTS.md C-1 is "missing args fail closed; no LitNull sentinels" (P3
fail-closed family), not parallel-representation/duplicate-authority. The
correct cite for rejecting a parallel ReflectedProgram<T> alongside Dag is
P2 single authority (INVARIANTS.md line 148: cost of change is proportional
to how many files encode the same fact).

Cite updated to "INVARIANTS.md P2 single authority" with inline gloss.

…debt

openai-pro REQUEST_CHANGES at gunbc#2079: substrate observation #1 had desired
endpoint ("future structural promotion of DeclarationRef") but no checkable
dissolution trigger — same P5 gap that #3 (tag_field asymmetry) had been fixed
for in commit 2601d7d.

Trigger now binding: promote DeclarationRef when EITHER
  (a) audit-row #14 (declaration_name_preference_rank / declaration_by_name
      rank-table) closes — dsl/std ↔ src/v3/std module convergence makes
      name-keyed identity unambiguous and structural module identity available,
  OR
  (b) any DeclarationRef-typed consumer surfaces a string-identity bridge per
      feedback_opaque_strings_attract_heuristics (heuristic patching, naming-
      convention dispatch, suffix/prefix matching).

Worker MUST add debt-paydown row before merging carrier-introduction PR (same
pattern as the tag_field debt requirement).

…-PAFS row

codex BLOCKING at gunbc#2079: docs/briefs/r3-pr-e6-g1a-option3-static-lens-worker.md:169
still said TC1/V1 "waits for Q-Reification and the carrier landing", contradicting
the same brief's lines 15-19 + 148-153 saying Dag IS the carrier and no separate
carrier lands.

Fixed:
1. e6-g1a brief line 167-170 paragraph: clarified V1 waits for consumer-wiring
   work (lens fold consuming Dag via .dag body authority through Evaluator), NOT
   for a carrier-introduction.
2. r3-program-plan.md:954 Q-PAFS row text was the same shape: "Resume after
   Q-Reification + ReflectedProgram<T>" — contradicted my new Q-Reification row
   in the same diff. Updated: Q-Reification STOP CLEARED 2026-05-07 (Option A);
   remaining hold = Branch B η non-vacuity only.

Out-of-scope-for-this-PR: docs/briefs/r3-pr-e6-g1a-option3-feasibility-probe.md
contains 4 stale cites but is not modified in this PR; stale-on-main can be
swept in a follow-up if needed (single source of truth is the e6-g1a-static-lens
worker brief, not the feasibility probe per Q-PAFS Path A acceptance).

…+ #3

codex BLOCKING at gunbc#2079 line 22: my brief mis-read services.dag:28-36.
The text actually says "No separate InputFieldRef carrier is introduced here,
since ParamToken.name already carries the same shape and adding a wrapper would
duplicate without strengthening the structural invariant" — i.e., InputFieldRef
does NOT exist; the comment REJECTS the wrapper.

Fixes:
1. Substrate observation #2 reframed: no FieldRef-shaped carrier exists at HEAD;
   services.dag:28-36 precedent argues against wrapper unless it strengthens
   structural invariant. New (a)/(b) STOP-and-PING:
   (a) follow services.dag precedent — wire_tag_field: String + key invariant
       on wire_tag_values + fixture-load fail-closed check;
   (b) introduce typed FieldRef — must justify per "duplicate without
       strengthening" test.
2. Carrier shape (line 19): wire_tag_field: FieldRef → {String|FieldRef}
   pending observation #2 resolution.
3. Substrate observation #3 reframed: InternallyTaggedObject asymmetry is
   conditional on path (b); under path (a) no asymmetry exists. Trigger
   correspondingly conditional. Removed stale "InputFieldRef classified" trigger
   clause.

…ed entry

openai-pro REQUEST_CHANGES at gunbc#2079: CoproductProjection shape split
per-variant data across two parallel maps (variant_field_projections +
wire_tag_values), admitting illegal states where keysets drift (P2 boundary
discipline / illegal-states-unrepresentable).

Fix: introduce CoproductVariantProjection { field_projection, wire_tag_value }
as the per-variant keyed value; CoproductProjection.variant_projections becomes
Map<VariantId, CoproductVariantProjection>. Single keyed authority per variant.

Director's binding constraint #2 enumerated the two fields separately but said
"refine in implementation as ergonomics demand" — consolidation preserves the
substantive constraints (typed WireTagValue leaf, structural per-variant
projection) while enforcing keyset alignment by carrier shape.

Empty-payload variants encoded via FieldProjection::Empty constructor (or
analog), not via map-absence.

…-and-PING umbrella

openai-pro REQUEST_CHANGES at gunbc#2079: 2 BLOCKING findings.

1. Path (a) at line 43 still referenced "Map<VariantId, WireTagValue> key invariant
   on wire_tag_values" — that's the superseded split-map vocab; the consolidated
   shape is Map<VariantId, CoproductVariantProjection> on variant_projections.
   Path (a) now references the consolidated map; per-variant WireTagValue lives
   inside CoproductVariantProjection.

2. Pre-ratification umbrella at line 36 said "all 3 dispositions pre-ratified,
   proceed without re-pinging" — but observation #2 was re-opened after the
   codex InputFieldRef finding and explicitly says STOP-and-PING. Contradictory.
   Umbrella now scoped: observations #1 + #3 are pre-ratified; #2 is re-opened
   STOP-and-PING — worker MUST escalate before choosing path (a) vs (b).

…issolution audit

Director ratified split disposition at gunbc#828 #issuecomment-4394696074:
descent_execution_proof STANDS ALONE (consumer-side termination-contract
substrate function with fail-closed residual enumeration; folding into
T-E-P-Producer-Broadening explicitly rejected — different concern axis).

Canvas surfaces 3 carrier-shape options for the residual enumeration per
Director's coproduct-dissolution audit suggestion:

α: 4-variant coproduct verbatim from §10.3 row 966 (Missing | Unknown |
   Incomplete | NonStrict)
β: 3-axis dimensional product (presence × completeness × strictness)
γ (recommended): reuse DescentEvidence at termination.dag:14-17 for
   "absent/unknown" via EvidenceUnknown(DescentEvidence) payload-variant +
   separate EvidenceIncomplete — ratchets variant count 4 → 2 via dimensional
   folding while honoring services.dag "no parallel wrapper" precedent.

Mgr recommendation γ; β rejected unless 3 axes provably compose orthogonally.

…ty map, no new enum variant

codex BLOCKING (post-merge of #2079, on commit 85ceb85 — same brief is now on
main): my Row #6 disposition told the worker to introduce a new
BootstrapAuthority::Pipeline variant ("extend the enum if needed"). That
violates P2 single-authority — src/v3/std/bootstrap_authority.dag:90 already
has "src/v3/compiler/pipeline.dag": CompilerAuthority, classifying pipeline.dag
under the existing CompilerAuthority variant. The :14-17 comment is explicit:
"the path itself is the BootstrapAuthoritySet map key; variants carry no
duplicate path payload" — single authority, not extension-by-variant.

Fix: Row #6 now instructs worker to derive the typed key from the existing
bootstrap_authority-map witness (BootstrapAuthorityKey threading the existing
CompilerAuthority classifier), refining the constructor surface if needed —
NOT introducing a new enum variant. STOP-and-PING criteria updated to forbid
new-variant resolution under any path.

…riant residual)

Director ratification at gunbc#828 #issuecomment-4395060514:
- DescentResidual = EvidenceUnknown(DescentEvidence) | EvidenceIncomplete
  (4 → 2 dissolution: Missing+Unknown fold via DescentUnknown injection;
  NonStrict folds via NonIncreasing wrap; Incomplete retained — different
  concern axis from evidence-lattice)
- DescentEvidence 3-variant lattice at termination.dag:14-17 confirmed as
  authoritative composition target
- Type signature from §10.3 row 966 confirmed verbatim-binding

Director-asked canvas-shape verification absorbed: worker STOPs if
EvidenceIncomplete decomposes into payload-variants (timeout / depth-bound /
evaluator-error-during-proof-construction); proceeds as 2-variant otherwise.

7 same-slice acceptance gates incl Evaluator E2 #1971 consumer wiring in same
PR + §10.3 row 966 row-text refresh to cite γ-disposition.

Worker pin: quick-koi-190 (pre-authorized per §10.3 row 966).

Auto-spawn HOLD per L-sized threshold; surgical-recreate path ratified
case-by-case if critical path blocked.

…d via NonStrictEvidence subset; delete superseded canvas

openai-pro REQUEST_CHANGES at gunbc#2105: 2 findings.

1. BLOCKING (LAYER MODEL / illegal states unrepresentable): worker brief
   shape `EvidenceUnknown(DescentEvidence)` admitted EvidenceUnknown(Strict)
   even though the canvas itself acknowledged Strict-isn't-a-residual as
   illegal. P2 requires API-level enforcement, not prose convention.

   Fix: introduce typed subset `NonStrictEvidence = NonIncreasing |
   DescentUnknown`; residual now `EvidenceUnknown(NonStrictEvidence)` —
   illegal-states-unrepresentable by construction. NonStrictEvidence lands in
   same file as DescentResidual; composes with existing 3-variant
   DescentEvidence via inhabitation, not re-definition.

2. NON-BLOCKING (live-state drift): canvas + worker brief both visible with
   "ratification needed" vs "ratified" status — same P2 single-authority
   shape as the S5 canvas/worker-brief co-existence at #2079.

   Fix: delete docs/briefs/r3-substrate-descent-execution-proof-canvas.md
   (worker brief frontmatter already names it as superseded; with canvas
   gone the live authority is unambiguous).

… row

codex BLOCKING at gunbc#2105 line 47: my brief cited "§10.3 row 966" but the
actual line is now 986 (after my Q-Reification row insert in PR #2079 shifted
§10.3 by 20 lines). Reviewer's "no such section" claim is wrong on substance
(file + section + row all exist) but the line drift IS real.

Fix per feedback_section_anchors_over_line_numbers (Director calibration in
gunbc#2079): replaced all "§10.3 row 966" with "§10.3 Q-EVAL-Descent-
Termination-Contract row" — name-anchor instead of line-anchor, drift-immune.
5 occurrences cleaned (closure predicate, acceptance gate #3, gate #5, STOP
criterion, worker pin justification). Stylistic "row row-text" repetition
collapsed to "row text".

…osition shape (#1957)

Pre-staged per Director endorsement of T-CostLens-Composition canvas-shape
authoring. Surfaces 3 composition options for the Lens<SymbolicCost> instance:

α: two separate lenses, externally joined — REJECTED (violates §1.8 gate #39
   no_coercion_cost_dimension by construction)
β: single Lens<SymbolicCost> with composed witness in read — strong but
   requires Lens<C> carrier-shape refactor (target-context threading)
γ (recommended): Lens<SymbolicCost> reads structural cost via algebra-fold +
   target-realization composed via existing Lookup<SymbolicCost> substrate at
   lookup.dag:48-60 — preserves generic Lens<C> carrier; satisfies all 4 §1.8
   gates (#37-40) by construction; aligns with feedback_audit_adjacent_authority_first

Adjacent substrate verified at HEAD: lens.dag:70-77 (Lens<C>), algebra.dag:12+
(SymbolicCost 7-variant + Semiring), lookup.dag:48-60 (Lookup<SymbolicCost> +
MissingCost lens-boundary).

Pre-staged per Director endorsement. Q-Workflow-As-Data-Carriers (§10.3 row 983)
named 5 carriers; grep-verified at HEAD that 4 of 5 ALREADY EXIST in
dsl/extdeps/github/actions.dag (218 lines). Only WorkflowSecret<Name> is
wholly net-new substrate.

Surfaces 3 options:
α: maximalist 5-carrier introduction in dsl/std/workflow.dag — REJECTED
   (admits parallel-representation debt vs audit-receipt #1771 reuse-first
   directive)
β (recommended): minimalist — only WorkflowSecret<Name> + Cron<Schedule>
   refinement net-new; lens consumes extdeps.github.actions directly. Honors
   feedback_audit_adjacent_authority_first.
γ: like β + WorkflowObservationAnchor for typed lens-consumption-shape;
   natural ratchet from β if evidence accumulates.

Sequencing: dispatch-ready post-T-LBP COMPLETE per §S4 design-schedule:95;
brief authoring lands in advance per pre-staging discipline.

Director ratification at gunbc#828 #issuecomment-4395691775:
- γ option ratified (Lens<SymbolicCost> + Lookup<SymbolicCost> composition)
- Lens<C> generic at lens.dag:70-77 confirmed authoritative (no refactor in scope)
- symbolic_cost_dimension: AnalysisDimension<SymbolicCost> defers to separate
  Dimensions sub-lane

Critical reframing absorbed: src/v3/lenses/cost.dag ALREADY EXISTS (status:
STRUCTURALLY TERMINAL; BEHAVIORALLY PROXY). T-CostLens-Composition is
behavioral-completion + target-realization-wiring, NOT P1 carrier introduction.
Worker reads existing lens; advances PROXY → BEHAVIORALLY COMPLETE via
Lookup<SymbolicCost> composition.

8 same-slice acceptance gates incl §1.8 #37-40 + #70 demonstration + lens
status header refresh + §10.3 row text refresh.

Out-of-scope (deferred per Director): symbolic_cost_dimension; Lens<C>
generic refactor (STOP-and-PING if implementation reveals need).

Canvas deleted per single-authority discipline (same precedent as S5 +
descent_execution_proof canvas deletions).

…ctoring tested, ε precedent does NOT apply)

Director authorized canvas authoring at #828 c#4402669133 as
parallel structure to Q-Cost-Composition-Layering (ε RATIFIED). Substrate-
grep on src/v3/lenses/complexity.dag at HEAD shows the factoring claim
DIFFERS from cost-lens:

- Cost-lens needed (target-agnostic shape × target-specific values)
  factoring → Rust-side composition (ε)
- Complexity-lens has NO target-specific axis; output is structural
  property of DAG topology + algebra-instance composition; substrate-
  native fully-on-.dag-side completion

Mgr provisional reading: ε precedent does NOT apply; complexity-lens
BEHAVIORAL COMPLETION is direct slice-tier substrate authoring (carrier
introduction follows SymbolicCost precedent + T-E-P P1 carrier
consumption). Director ratification ask: Q1 (factoring finding correct),
Q2 (slice-tier directly bypassing canvas), Q3 (fresh worker pin).

Cross-Mgr: Verification Mgr (#2075) pinged on v2-oracle snapshot capture

… (Q1/Q2/Q3 RATIFIED)

Pre-authored brief for complexity-lens BEHAVIORAL COMPLETION substrate
work per Director Q1/Q2/Q3 ratification at #828 c#4402714255.

Three deliverables: carrier introduction (ComplexityCost / WorkSpan /
AsymptoticClass following SymbolicCost precedent) + lens widening
(complexity.dag PROXY → COMPLETE) + T-E-P P1 carrier consumption
(DescentEvidence / CallPattern / SubValueRelation for asymptotic
classification of recursive-call behavior).

Indirect-variant dependency surfaced as worker-grep concern at slice-
authoring time (T-E-P P1 Slice 5+ pending; eager-bat-178 stream).

Cementing test (#1950) is separate downstream brief; v2-oracle snapshot
ownership pending Q4 cross-Mgr ratification.

Worker pin: fresh-pool pick at dispatch time (NOT eager-bat-178 per
Director Q3 framing; NOT fierce-ram-21 busy with cost-lens ε).

Same-window-dispatch discipline applies post-canvas-merge (PR #2197).

Pre-authored vs pre-known discipline applied per

…hority (codex BLOCKING fix)

Codex BLOCKING (3 findings) at #2199 sha 7a8bb6d:
1. Brief authored against missing canvas instead of reconciling with
   docs/design-complexity-lens-behavioral-completeness.md (which exists
   at HEAD with comprehensive substrate spec)
2. Producer coverage treated as optional corpus scope; should be hard
   T-E-P-Producer-Broadening prerequisite
3. Stale/non-in-repo planning authority cited; should be r3-structure.md
   row 146 (T-LBP slice 1)

All three BLOCKING findings VALID — substrate-grep-before-authoring
discipline failure on my part (feedback_substrate_grep_before_authoring
already memorialized; violated own discipline).

Rewrite delegates carrier shape, dimension wiring, and consumer rewrite
to live design doc §§1.1-1.6 verbatim:
- §1.1 SymbolicCost — already at algebra.dag; no change
- §1.2 SizeVariable — display_name enrichment
- §1.3 work_dimension + span_dimension — two AnalysisDimension instances
- §1.4 AsymptoticClass + BoundedLattice instance
- §1.5 Certainty (cost-aware composition; no lattice)
- §1.6 cost_bound_to_symbolic projection
- §1.7 ComplexitySummary record + lens widening

T-E-P P1 hard prerequisite per design's authority discipline + r3-
structure.md row 146; STOP-and-PING if T-E-P P1 not COMPLETE at slice
authoring time. Authority cites updated to live r3-structure.md row 146.

…procedure per Q6 RATIFIED)

Director Q6 RATIFIED canvas-tier-required at #828 c#4403163639
for PerfWithinBaseline TestPredicate variant authoring. Three substantive
substrate-shape questions resolved:

Q1 baseline shape: (a) literal-Int rejected as strict-mirror-of-CostBounded
defeats semantic load; (b) DeclarationRef-to-stored-data composes
LensOutputEquals + data X: SymbolicCost precedent at HEAD; (c) runtime-
fixture-injection over-authors. Mgr lean (b).

Q2 ComparisonOp composition: (i) reuse existing ComparisonOp via test-
runner-side resolution matches LensOutputEquals path; (ii) new relative-
op-set introduces parallel-representation debt. Mgr lean (i).

Q3 baseline-storage scope: (α) in-scope slice authors example data; (β)
out-of-scope variant-only slice + PB consumer authors baseline data
matches existing layering. Mgr lean (β).

Combined Mgr lean: Q1(b) + Q2(i) + Q3(β) — variant authored as
compositional extension; baseline-storage is PB consumer-tier work.

Cross-Mgr: PB Mgr #2138 worker (crisp-swift-433) holds dispatch on #2204

- P2 explicitly post-R3 per Director-locked recommendation (zero in-R3
  effort; structural close per r3-structure.md:461 'R3 deliverable is
  structural close; perf is downstream')

Mgr lean: P2 — Director-locked recommendation explicit; trigger-
condition ('someone authors perf-budget claim with concrete numbers
and tooling') not met; R3 horizon constraint argues against multi-
slice perf-budget substrate adding to 5-orthogonal-dependency picture.

Original canvas at q-perf-within-baseline-canvas.md retained with
SUPERSEDED-BY header per durable-decision-record discipline.

5th discipline-failure of 2026-05-08 cycle: substrate-grep verified
substrate-precedent but missed consumer-side requirement at canonical
authority doc; Director self-flagged symmetric two-axis verification
gap; canvas-finding-taxonomy needs precondition 'consumer-side
requirement grep-verified at canonical authority doc'.

…r-condition framing per Director c#4403297623

Director caught second-axis grep failure on revised canvas: my P2
reasoning #1 ("path-trigger condition for P1 is not met") was
structurally wrong. Existing tooling at HEAD substantially meets the
Director-locked 2026-04-28 trigger-condition ("someone authors the
perf-budget claim with concrete numbers and tooling"):

- docs/briefs/r3-pb-tier3-perf-budget-worker.md
- docs/audit/c1-tier3-perf-budget-readiness-matrix.md
- src/v3/compiler/benches/tier3_mirror_perf.rs
- docs/audit/c1-tier3-baseline-capture-procedure.md
- docs/audit/c1-r3-canonical-bench-host-decision-matrix.md

Plus thresholds (≤2× median, ≤5× p99) + capture discipline (N=3 min,
N=5 preferred) + canonical bench host option matrix.

P1 is bridging existing tooling to substrate (compositional-extension),
NOT multi-slice greenfield genuinely-novel pattern-5 as originally
framed. Smaller scope than canvas-finding-taxonomy pattern 5 implies.

Path-call genuinely depends on PB Mgr's R-3 (canonical CI bench host)
+ R-7 (tier3_baseline.json baseline-capture path) decisions per their
audit response at c#4403059897. Path-call DEFERRED to cross-Mgr
coordination outcome with PB Mgr (#2074); Substrate Mgr surfaces with
corrected framing this turn.

Sixth discipline-failure of cycle (mine, second-axis grep gap on
existing-tooling state); same-class as Director's first-axis grep gap
on consumer-side requirement at the prior turn. Memorialized as
two-axis verification discipline anchor.

…-generation lean)

D1 substrate-shape question per Q-ValueBody-Isomorphism RATIFIED at
#828 c#4403972737. Variant-inventory readiness input from
PR #2218 (merged 2026-05-08) confirms drift: Rust 5 variants vs
substrate 3 constructors; asymmetry on Scalar+List Rust-only +
Map payload-parity-with-semantic-gap.

Two-axis verification at HEAD:
- Substrate-precedent: codegen tooling exists (regen_bootstrap_emit;
  5 _generated.rs files; regen_bootstrap binary). Pattern-3 strict-
  mirror codegen extension applies; no pattern-5 P1 procedure.
- Consumer-side requirement: V1 worker brief explicitly names mirror-
  parity-vs-codegen-generation as D1 path-pair.

Mgr lean: (b) codegen-generation. Path (a) mirror-parity perpetuates
parallel-representation debt; (b) dissolves the dual-taxonomy class
by construction (substrate canonical, Rust codegens). Map dup-key gap
handled via (ii) Rust-side post-codegen wrapping (substrate stays
minimal).

Director ratification ask: D1 (b) + D1-followup (ii).

Carrier slice path post-ratification: extend regen_bootstrap_emit;
add Scalar+List constructors to substrate; regen + remove hand-Rust
enum; handle Map dup-key per ratified followup. Worker pin fresh-pool
per same-window-dispatch.

…cite (codex BLOCKING fix)

Director ratified (α) amendment-PR at #828 c#4404398425
post-codex-BLOCKING at PR #2222 c#4404360699.

Canvas originally cited regen_bootstrap_emit.rs as codegen authority
for ValueBody runtime mirror; corrected to scripts/regen_runtime_mirrors.py
which is the substrate→Rust runtime-mirror generator (reads substrate.dag,
emits dag_scalar_generated.rs etc.). regen_bootstrap_emit.rs is a
separate codegen system that generates bootstrap_generated.rs (bootstrap
parser/lower compile snapshot).

D1 (b) codegen-generation ratification UNCHANGED; only authority-path
cites corrected. Carrier slice path at canvas §6-step plan now references
correct runtime-mirror generator. Canvas inline notes mark amendment
location for future-reader audit trail.

8th cycle-tier framing-failure (Mgr-tier; same fine-granularity gap
parallel to Director-tier failure at c#4404256128). Two-axis verification
discipline applied at insufficient granularity (verified codegen-tooling-
exists but didn't disambiguate against bootstrap-vs-runtime-mirror systems).

Discipline anchor refinement: when canvas cites a codegen system /
tooling / authority path, identify the SPECIFIC generator/handler for
the target-file-class. Don't accept 'tooling exists' at coarse granularity.

Director confirmation: amendment-PR ratified; standing-authority merge applies

Canvas authority cite correction (regen_bootstrap_emit.rs → scripts/regen_runtime_mirrors.py) is the right surgical fix per my disposition (α) at c#4404398425 + your absorption at c#4404441818. D1 (b) ratification stands; only authority cite needed correction.

Empirical observation (worth noting cycle-side)

This PR's auto-opened body ALREADY carries the new ctrl#818 scaffold-content template:

## Worker attestation
- [ ] Title describes the change ...
- [ ] PR body summarises ...
- [ ] Tests run ...
- [ ] If this closes a work item, the body contains a `Closes #N` directive.
- [ ] No commits on this branch are surprises ...
- [ ] No secrets / credentials / large binaries staged.

## Summary
TODO: replace this paragraph ...

## Test plan
- TODO: list the commands ...

This is the first post-ctrl#818 auto-opened PR with the new template — confirms ctrl#818 deploy worked structurally. Debt-Paydown's wave 5 worker (#2225) just got their empirical baseline sample.

Cross-link: confirms the third sub-fix in the ctrl picture I summarized at c#4404446463 — scaffold-content infrastructure ✓ DEPLOYED is now empirically validated post-merge.

Flip to ready

Standing-authority merge applies. Docs-only (+7/-7); no code/test surfaces; no SG-0 ratchet impact.
