RT4a: Synthesize compute nodes for complex return expressions by briansrls · Pull Request #89 · gunb-ai/gunbc

briansrls · 2026-02-27T19:57:30Z

Summary

Implement RT4a support to handle complex return expressions (BinOp, UnaryOp, If, Match, Pipe) by synthesizing dedicated compute nodes that evaluate them at runtime. This allows callables to return computed values instead of just direct references to callable/service outputs.

Key Changes

New PrimitiveOpKind::ReturnExprCompute: Added a primitive operation kind that stores a lowered expression to be evaluated at runtime with actual input values.
Expression leaf collection and rewriting: Implemented collect_return_expr_leaves() to walk AST expressions, extract all leaf references (callable/service outputs and parameters), and rewrite them as input port identifiers (input_0, input_1, etc.).
Compute node synthesis: Added synthesize_return_compute_node() to create DAG nodes with:
- Input ports for each unique leaf reference
- Output port matching the return output name/type
- Stored lowered expression for runtime evaluation
- Automatic wiring from source nodes to compute node inputs
Runtime execution: Implemented ReturnExprComputeOp in the resolver that evaluates the lowered expression using the evaluator with actual input values.
Diagnostic infrastructure: Added LowerWarning::UnwiredReturnOutput to track unsupported expression types that fall back to the old behavior (no wiring), with structured diagnostics for future diagnostics channels.
Integration points:
- Updated resolve_return_expr_source() to attempt compute node synthesis for complex expressions
- Updated wire_callable_return_outputs() to emit warnings when expressions cannot be wired
- Updated emit pipeline and Rust runtime to handle the new primitive kind
- Updated test fixtures to reflect new pure node count

Implementation Details

Leaf resolution uses the same logic as existing parameter/callable/service source resolution
Rewritten expressions reference inputs by name, allowing the evaluator to resolve them from the compute node's input map
Unresolved references (unbound variables) cause fallback to no wiring, triggering a warning
The compute node is created with a unique ID based on module, callable, output name, and disambiguator
Output type is preserved from the original return port definition

RT4a — Synthesize ReturnExprCompute nodes for BinOp/UnaryOp return expressions. The lowerer's resolve_return_expr_source() previously silently dropped complex expressions (BinOp, UnaryOp, If, Match, Pipe) by falling through to `_ => None`. Now BinOp and UnaryOp expressions are lowered into PrimitiveOpKind::ReturnExprCompute nodes that collect leaf references, rewrite them to input_N identifiers, and evaluate the lowered expression at runtime via evaluate_fn_body(). This fixes the root cause of the gunbc-ci false failure where overall_success (build.success && test.success && clippy.success) was silently dropped, producing Value::Skipped. RT4b — Structured diagnostic in execute_with_declared_output_passthrough() for when a declared output port has no wired __out: input and falls back to Value::Skipped. Defense-in-depth against silent output loss. RT4c — LowerWarning::UnwiredReturnOutput structured diagnostic type for when the lowerer can't wire a non-optional return output. Compile-time defense against silent expression dropping. Also reverts the ci.rs success_port workaround back to overall_success, and fixes pre-existing snapshot drift in s5_ci_pipeline.json and module_graph.rs (workflows.makegen 2→5, std.virtual_io added). https://claude.ai/code/session_019makpLTtwnnCyyPaP1yJCq

Wave 1 (safety fixes): - RT38: Replace FileOp panic with LowerError::InvalidFileOp - RT39: Replace silent advance on non-ident auth/auth_input with parse error - RT40: Add is_optional field to OutputFieldSpec, replace string suffix check Wave 2 (parser/AST): - RT42: Add PipeMethod enum (24 variants) replacing hardcoded string allowlist - RT47: Extract try_parse_multi_param_lambda() with read-only lookahead Wave 3 (eval/fidelity type safety): - RT45: Add Value::Enum variant for typed enum values from evaluator - RT46: Replace fidelity silent fallbacks with explicit panic on classification failure Wave 4 (lowerer enhancements): - RT43: Nested field access via ReturnExprCompute, delete extract_secret workaround - RT44: Add max_by pipe method to evaluator, 14 new eval tests expanding coverage 18 files changed across core/ir, core/daglang, core/exec, gunbc-dag, dsl. https://claude.ai/code/session_019makpLTtwnnCyyPaP1yJCq

The parser rejected `?.` with "ternary operator is not supported", causing `local_auth()` body to be marked lossy (empty stmts). The lowerer couldn't extract any transport nodes, forcing runtime-only execution. Fix: when the parser sees `?` followed by `.`, it desugars `expr?.field` to `if expr != None { expr.field } else { None }` — no new AST variant needed, fully transparent to lowerer and evaluator. Result: `local_auth()` in `dsl/std/patterns.dag` now parses non-lossily. The lowerer extracts shell.Env.Get, fs.read, shell.OAuth2.RefreshToken, and shell.GCloud.AuthPrintAccessToken as compile-time transport nodes. All 287 daglang-cli snapshot tests pass unchanged. https://claude.ai/code/session_019makpLTtwnnCyyPaP1yJCq

…me resolution - OutputValueKind enum on OutputFieldSpec with value_kind() method — replaces duplicate match field.type_id.as_str() in extract_output_field() and default_output_value(). Single canonical dispatch point. - workflow_unit_commands() now uses catalog::resolve_workflow_variant() for name resolution instead of reimplementing normalize + alias handling. - Fix passthrough_callables allowlist for RT43 credential.dag changes (acquire_gcp_secret now appears as passthrough callable after extract_secret deletion). https://claude.ai/code/session_019makpLTtwnnCyyPaP1yJCq

- GenericRestParseOp status code check: already done (rest.is_success() at line 185, with full error context including auth) - GNUmakefile --mode=ensure flag: already fixed (no invalid flags) - find crates exit 1: fixed by RT-I4 (SplitLines returns empty list) - looks_effectful_without_kind: corrected classification — NOT dead code, it's a validation safety net, low priority https://claude.ai/code/session_019makpLTtwnnCyyPaP1yJCq

…obligation.rs Production code in testgen/obligation.rs was using raw "res:credential" string literal instead of PortName::RESOURCE_CREDENTIAL. Test-only assertions are left as-is per RT31 migration policy. https://claude.ai/code/session_019makpLTtwnnCyyPaP1yJCq

Both branches changed obligation counts: our branch added 1 obligation (RT changes), main added 3 readonly_targets (blue team SDLC PR). Combined: readonly_targets=3, total_obligations=231. https://claude.ai/code/session_019makpLTtwnnCyyPaP1yJCq

… classification Address three PR feedback issues in return-expression compute node synthesis: 1. Parameter leaves: resolve_leaf_source now resolves parameters to param_source_* nodes when they exist in the DAG (func items), and returns None when they don't (fn items). Added DAG node existence check to prevent missing-node errors. 2. If/Match recursion: collect_return_expr_leaves now recurses into If, Match, Call, and Record expressions using a recurse! macro (avoids closure borrow issues). Pipe, Lambda, and For expressions are intentionally NOT recursed into — Pipe has complex runtime evaluation requirements and lowest-precedence parsing issues; Lambda introduces bound variables the walker can't distinguish from DAG nodes; For is effectful iteration. 3. exec-runtime classification: ReturnExprCompute nodes are now classified as HandlerKind::Passthrough instead of returning None, which caused the emit pipeline to skip them. https://claude.ai/code/session_019makpLTtwnnCyyPaP1yJCq

…brief — status PROPOSAL pending Substrate Mgr canvas Codex BLOCKING at sha 3c96212 (PR #1902) surfaced 3 substantively valid findings; all PM grep-verified before applying. Finding 1 (optional+invariant origin → typed-sum origin) APPLIED: type EmissionOrigin = SubstrateDeclMirror { span: SourceSpan } | FoldRuleAutoEmit { rule_name: String } type EmissionProvenance { emitted_line: Int origin: EmissionOrigin // REQUIRED } The Disj carrier makes "at least one origin class present" structurally true; eliminates the prior optional+runtime-invariant structural recovery pattern. Per feedback_state_space_vs_behavioral_invariants (type enforcement > API enforcement). Finding 2 (Lens<C> read shape category mismatch) FLAGGED: Lens<C>.read: fn(Dag, Behavior) -> Witness<C> per src/v3/std/lens.dag — per-Behavior read. Emission provenance is per-emitted-LINE, not per-Behavior. Real category mismatch. Brief reframed to status: PROPOSAL pending Substrate Mgr canvas. Three reframing paths surfaced for Substrate Mgr disposition: (a) per-Behavior framing (Lens<C>-compatible; narrower scope; doesn't directly support Brian's slide visualization) (b) per-emitted-line instrumentation (NOT a lens; matches Brian's visualization; different substrate shape entirely) (c) withdraw + canvas first; re-author once shape ratified. PM recommendation: (c). Substantive reshape needs Substrate Mgr canvas, not PM tactical pre-authoring. Finding 3 (§1.8 #89 already taken) APPLIED: PM grep-verified §1.8 #89 is `section_ref_substrate_landed` under T-Lens-Application-Surface (already declared 2026-05-06). My citation was wrong. Brief frontmatter retargeted to "TBD — gate authority pending"; cites 3 candidate retarget paths for Substrate Mgr disposition: (a) new gate under T-CostLens-Composition cluster (#37-#40 analog); (b) new gate under T-LAS; (c) deferred until per-Behavior framing ratified. Brief is now NOT dispatch-ready — explicitly PROPOSAL status until Substrate Mgr canvas resolves Finding 2 + gate authority.

…rector-ratified (#1902) * docs(briefs): add Lens<EmissionProvenance> worker brief — PM-authored under Director ratification Per Director ratification at gunbc#828 #issuecomment-4392256151 (zesty-bear-812 — "Lens<EmissionProvenance> as another Lens<C> instance per feedback_lenses_not_passes; Substrate authors instance carrier; Verification asserts gate") and Brian directive 2026-05-06 chat ("R3 has idle workers under several managers, so we should put them to work asap"). Brief covers: - EmissionProvenance C-type with fail-closed discipline (at least one of source_span / fold_rule present per emitted line per feedback_fail_closed_discipline C-8) - Lens<EmissionProvenance> instance per existing Lens<C> 6-field shape (Director-locked at src/v3/std/lens.dag); shape parity with existing T-CostLens-Composition Lens<SymbolicCost> precedent - Cementing test verifying inverse mapping closes (every emitted line has either populated source_span OR fold_rule; both-absent fails closed) - 4 STOP triggers (missing fold-rule names; Lens<C> shape gaps; third origin class surface; substrate-state-grep mismatch) - Cross-lane refs to T-LAS (instance becomes consumable via apply_lens post-T-LAS); Grounding (downstream consumer optional, R3 scope is instance landing only); T-CostLens-Composition (shape precedent) - Worker pin candidates: smart-ram-167 OR valiant-ibex-312 (Mgr discretion) - §1.8 ledger gate #89 emission_provenance_lens_landed (proposed) Brief is pre-authored per feedback_pre_authored_brief_queue discipline. Substrate Mgr disposes dispatch readiness at brief-PR-merge time; adjusts content lightly if substrate state shifts (does not re-author from scratch). Forward direction (.dag → diagnostic source-span) already exists structurally (SourceSpan on every Behavior + Declaration per dag.rs:47-48); inverse direction (emitted Rust → .dag origin) is implicit in the fold but not currently exposed as metadata stream. This lens instance landing exposes it. PR #1879 (emission-intuition slide) surfaced the gap; visualization claim benefits from this lens once landed.

Optional<T> canonical shape: PM grep-verified that .dag uses T? suffix (e.g., String? at src/v3/std/anthropic_schema.dag:115-119); named Optional carriers like OptionalDiagnostic exist at src/v3/std/dimensions.dag:41 but generic Optional is T? suffix. Updated EmissionProvenance C-type fields: - source_span: OptionalSourceSpan -> SourceSpan? - fold_rule: OptionalString -> String? Added explicit "Optional shape note" with grep references. 2. STOP trigger #1 (missing fold-rule names) reframed as likely prerequisite-not-mid-implementation-STOP: claude observed that STOP #1 is most likely-to-fire one — really a prerequisite, not a stop-condition. PM grep-verified at authoring-time that fold-rule names are NOT enumerable in src/v3/compiler/src/ (0 hits for RuleName / FoldRule / fn emit_derive). Updated STOP trigger #1 to surface this as PM-side recommendation: Substrate Mgr disposes resolution before worker dispatch (rule-name enumeration substrate as separate brief OR confirm grep was incomplete OR re-scope to land partial-provenance only). Avoids mid-implementation discovery of a hard prerequisite. Both observations are non-blocking per claude verdict (APPROVE) but worth applying for downstream worker quality + Substrate Mgr prerequisite-resolution-before-dispatch.

…#1902 PROPOSAL) Substrate Mgr canvas authored post-codex BLOCKING + PM disposition handoff at gunbc#846 #issuecomment-4392510255.

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.

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.

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.

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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.

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.

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.

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`.

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.

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.

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'.

Placeholder semantics REMOVED from registry path. Codex REQUEST_CHANGES surfaced that registered-predicate-without- contract = silent acceptance per feedback_fail_closed_discipline.

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.

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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.

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.

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.

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.

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`.

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-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).

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.

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").

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.

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.

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).

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.

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'.

Converted to function-name anchored form: `src/v3/compiler/src/lower.rs` (`lower_type_alias_refinements_phase` doc-block).

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.

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.

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.

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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.

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.

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`.

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).

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.

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.

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.

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.

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.

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'.

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).

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.

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.

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).

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.

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.

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.

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) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.)

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.

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.

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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.

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.

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.

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.

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'.

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.

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.

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).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): apply 2 claude APPROVE-with-observations refinements Per claude review at sha 3c96212 (PR #1902 #issuecomment-4392308244): 1. Optional<T> canonical shape: PM grep-verified that .dag uses T? suffix (e.g., String? at src/v3/std/anthropic_schema.dag:115-119); named Optional carriers like OptionalDiagnostic exist at src/v3/std/dimensions.dag:41 but generic Optional is T? suffix. Updated EmissionProvenance C-type fields: - source_span: OptionalSourceSpan -> SourceSpan? - fold_rule: OptionalString -> String? Added explicit "Optional shape note" with grep references. 2. STOP trigger #1 (missing fold-rule names) reframed as likely prerequisite-not-mid-implementation-STOP: claude observed that STOP #1 is most likely-to-fire one — really a prerequisite, not a stop-condition. PM grep-verified at authoring-time that fold-rule names are NOT enumerable in src/v3/compiler/src/ (0 hits for RuleName / FoldRule / fn emit_derive). Updated STOP trigger #1 to surface this as PM-side recommendation: Substrate Mgr disposes resolution before worker dispatch (rule-name enumeration substrate as separate brief OR confirm grep was incomplete OR re-scope to land partial-provenance only). Avoids mid-implementation discovery of a hard prerequisite. Both observations are non-blocking per claude verdict (APPROVE) but worth applying for downstream worker quality + Substrate Mgr prerequisite-resolution-before-dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): apply 3 codex BLOCKING findings on emission-provenance brief — status PROPOSAL pending Substrate Mgr canvas Codex BLOCKING at sha 3c96212 (PR #1902) surfaced 3 substantively valid findings; all PM grep-verified before applying. Finding 1 (optional+invariant origin → typed-sum origin) APPLIED: type EmissionOrigin = SubstrateDeclMirror { span: SourceSpan } | FoldRuleAutoEmit { rule_name: String } type EmissionProvenance { emitted_line: Int origin: EmissionOrigin // REQUIRED } The Disj carrier makes "at least one origin class present" structurally true; eliminates the prior optional+runtime-invariant structural recovery pattern. Per feedback_state_space_vs_behavioral_invariants (type enforcement > API enforcement). Finding 2 (Lens<C> read shape category mismatch) FLAGGED: Lens<C>.read: fn(Dag, Behavior) -> Witness<C> per src/v3/std/lens.dag — per-Behavior read. Emission provenance is per-emitted-LINE, not per-Behavior. Real category mismatch. Brief reframed to status: PROPOSAL pending Substrate Mgr canvas. Three reframing paths surfaced for Substrate Mgr disposition: (a) per-Behavior framing (Lens<C>-compatible; narrower scope; doesn't directly support Brian's slide visualization) (b) per-emitted-line instrumentation (NOT a lens; matches Brian's visualization; different substrate shape entirely) (c) withdraw + canvas first; re-author once shape ratified. PM recommendation: (c). Substantive reshape needs Substrate Mgr canvas, not PM tactical pre-authoring. Finding 3 (§1.8 #89 already taken) APPLIED: PM grep-verified §1.8 #89 is `section_ref_substrate_landed` under T-Lens-Application-Surface (already declared 2026-05-06). My citation was wrong. Brief frontmatter retargeted to "TBD — gate authority pending"; cites 3 candidate retarget paths for Substrate Mgr disposition: (a) new gate under T-CostLens-Composition cluster (#37-#40 analog); (b) new gate under T-LAS; (c) deferred until per-Behavior framing ratified. Brief is now NOT dispatch-ready — explicitly PROPOSAL status until Substrate Mgr canvas resolves Finding 2 + gate authority. PM tactical-authority limit acknowledged: emission-provenance is substantively richer than I initially scoped; Substrate Mgr canvas is the right next step, not worker dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): tighten EmissionOrigin — typed LangSpecRule ref, not arbitrary String Per codex BLOCKING inline at brief line 57 (sha 3c96212) — same finding-class as parent BLOCKING but more pointed: while my prior fix (commit 0110f73) eliminated the both-absent admittance via typed Disj, FoldRuleAutoEmit { rule_name: String } still admitted arbitrary fold-rule strings. P2 illegal-states-unrepresentable requires typed LangSpec rule ref, not free String. Fix: FoldRuleAutoEmit { rule: LangSpecRule } where LangSpecRule is a typed enumeration of LangSpec emission rules. Now both structural invariants hold by construction: - "at least one origin class is present" (typed Disj over the 2 classes) - "rule names are well-formed LangSpec identifiers" (typed enumeration) This reinforces the rule-name-enumeration prerequisite already cross-relayed to Substrate Mgr at gunbc#1739 #issuecomment-4392435376: LangSpecRule typed enumeration MUST exist as substrate carrier before this brief can dispatch. Substrate Mgr disposes: (a) author LangSpecRule enumeration substrate first; (b) confirm grep was incomplete and rules ARE enumerable elsewhere; (c) brief dispatched only after typed-rule prerequisite lands. Per feedback_state_space_vs_behavioral_invariants — eliminates structural-recovery pattern by making invariants type-true rather than runtime-asserted. Brief stays status: PROPOSAL pending Substrate Mgr canvas on Finding 2 (Lens<C> read-shape category mismatch) + Finding 3 (gate retargeting). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): deepen F2 reframing — Lens<C> read DOMAIN mismatch (not just granularity) Per codex BLOCKING inline at line 73 (sha c375eba): the Lens<C> read shape mismatch is deeper than initially framed. Initial frame: "Lens<C> is per-Behavior; goal is per-emitted-line — category mismatch on granularity." Deeper frame (PM grep-verified): Lens<C>.read domain is `Behavior = Value | Transform | Branch` per src/v3/std/substrate.dag:465. The brief's acceptance surface includes lines from: - Declaration-origin (e.g., pub enum Sum<A,B> from .dag type Sum declaration; pub struct HttpError from type HttpError declaration) - LangSpec auto-emits (e.g., #[derive], impl X { is_left }, impl X { new }) Declarations are at src/v3/std/substrate.dag:235 — structurally separate from Behaviors. Auto-emits have no .dag source at all. Both are OUTSIDE Lens<C>.read's domain entirely. So the mismatch is structural at TWO axes simultaneously: - Granularity: per-Behavior (lens) vs per-emitted-line (goal) - Domain coverage: Lens<C> can only read Behaviors; brief's acceptance includes Declaration-origin + auto-emits which Lens<C> structurally cannot see Reframing paths revised (deeper): (a) Per-Behavior, narrow domain — Lens<C>-compatible, EXCLUDES Declaration-origin + auto-emit lines entirely; very narrow; doesn't support Brian's visualization (b) Per-emitted-line instrumentation, NEW substrate — NOT a lens; requires substrate-fact-introduction (P1 procedure); matches visualization need (c) Withdraw + canvas first — stronger PM recommendation given the deeper mismatch PM-side stance: brief stays status: PROPOSAL pending Substrate Mgr canvas. The Lens<C> framing isn't just narrow; it's structurally insufficient for the brief's acceptance surface. Substantive reshape needs Substrate Mgr canvas + Director ratification on the right shape. Per feedback_corrections_must_grep_verify_source — both axes of the mismatch grep-verified: - Behavior shape at src/v3/std/substrate.dag:465 (3-variant Disj) - Declaration shape at src/v3/std/substrate.dag:235 (separate type) - Lens<C>.read at src/v3/std/lens.dag (per-Behavior fold) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): mark §S6 EmissionPathProjection carrier (L6) CLOSED — closure receipt for #1842 + #1852 - Append CLOSED 2026-05-07 marker to §S6 heading - Add closure receipt block citing absorbing PRs (#1842 carrier + populate; #1852 per-row projection conversion) - Note R2-side L6 gate (l6_structural_form_coverage) authority remains in T-Ground-CrossTarget-Meta per r3-structure.md:87 engine-reframe - Record PM-side discipline lesson (grep-verify work-shape at brief-authoring time) absorbed via #1979 near-miss Per Director ratification at gunbc#828 #issuecomment-4394697875 (path 1: R3 design-schedule §S6 close mark) following Grounding Mgr audit at gunbc#2063 #issuecomment-4394494437.

Codex BLOCKING flagged at gunbc#2103 review (commit b825bb0).

…dex 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).

…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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.
