Stop falling back on malformed cloud config

graph_cloud_config() currently falls back to default_local_dev_config() for any resolve_graph_cloud_config() error, not just the “no source configured” case documented above this function. If GUNBC_CLOUD_CONFIG_JSON/GUNBC_CLOUD_CONFIG_TOML is present but malformed (or references an unknown namespace), the process silently uses dev defaults instead of surfacing misconfiguration, which can route credential reads/writes to the wrong project/prefix in CI or production-like runs.

Honor child scope_merge override when merging defaults

The merge logic ignores a child profile’s scope_merge = replace by inheriting the parent mode whenever the child value is Replace. With a parent set to Union, a child cannot switch back to Replace, so inherited intent scopes keep unioning even when the child explicitly requests replacement. This makes profile inheritance behavior incorrect for valid policy configurations.

…e question) Sibling canvas to q-lens-target-context-canvas.md. Director α-revised supersession at gunbc#828 #issuecomment-4400920572 elevated ε path (Rust-side cost-composition wiring; preserves cost.dag PROXY) from slice-tier to canvas-tier. Authored per Q-PAFS template: - Factoring claim: cost = (target-agnostic-shape SymbolicCost algebra) × (target-specific-values per-primitive realization-cost data loaded Rust-side) - Test against feedback_abstraction_layering (Director-named anchor at gunbc#828 c#4400921658): pure objective concepts × language-agnostic LanguageSpec × emit-side composition. Compliance test for each layer. - Pro factoring (ε structurally honest): SymbolicCost algebra is target- agnostic at HEAD; Rust-side composition is natural home; #38/#39 substrate- already-aligned per Slice 1 finding. - Con factoring (ε is parallel-representation debt): N parallel Rust-side compositions if multiple lenses need target-context; lens-framework abstraction stops at substrate boundary; future lenses hit same dilemma. Mgr provisional reading: factoring honest for COST specifically; NOT generalizable. ε right framing IF cost is the singular need + factoring holds. If N>1 target-context-needing lenses surface, β-extended (option (i) from sibling canvas) becomes the right path. Director ratification ask: 3-way choice (ε) Cost-specific Rust-side composition; preserves cost.dag PROXY (β-extended option (i)) Lens<C> refactor for LanguageSpec parameter (both sequenced) ε now for cost; β-extended later if N>1 Framework discipline anchors: - feedback_abstraction_layering (Director-named for this canvas) - feedback_parallel_representation_debt - feedback_same_slice_dissolution_discipline Canvas-pair complete; sibling canvas + this canvas address the deeper cross-cutting axis: target-context belongs .dag-side (β-extended) or emit-side (ε)?

Partial retirement was explicitly rejected 2026-04-29 (Director acceptance #1130 / dispatch #1139). Changes: - Add Ledger-discipline preamble: umbrella row stays Open; receipt updates audit-packet enumeration, NOT bridge_ledger.dag. - Acceptance #3 reframed: do NOT mutate bridge_ledger.dag; mark rows #2 + #6 retired in the audit packet only. - Authority anchor updated: status=Open (not Proposed); add r3-structure.md:115 + bridge_ledger.dag:125-129 line refs. - Cross-Mgr section reframed: umbrella ratchet cannot flip on this PR alone; Verification's ledger-zero audit progress field is post-merge tracking, not a same-slice pre-merge blocker. Reconciles with BLOCKING finding (Director calibration #1 assumed umbrella ratchet could flip on partial retirement, which r3-structure.md:115 forbids).

Surfaces 3 substrate observations for STOP-and-PING (DeclarationRef String alias; FieldRef does-not-exist-at-HEAD; tag_field String asymmetry) — worker must escalate, not silently work around.

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

DeclarationRef alias: accept (b) + debt note (re-escalate only on same-slice break) 2. FieldRef: grep-decide between InputFieldRef-as-specialization vs rename 3. tag_field String asymmetry: typed introduction + debt note for migration Worker proceeds without re-pinging unless evidence forces escalation.

ReflectedProgram<T> rejected. Gate A patches: 1. r3-program-plan.md §10.3: new Q-Reification row marked RATIFIED with PR #2096 merge link + Gate A receipt scope (this PR + #1960 closed-as-non-addition). 2. r3-v-pattern-a-tc1-v1-worker.md: 3 sites — status header (Q-Reification CLEARED, Branch B η non-vacuity remains), worker-pin gate, E6-G1.a/E3 producer dependency. Replaces ReflectedProgram<T> with consumer-wiring nuance: lens fold consumes Dag via .dag body authority through Evaluator. 3. r3-pr-e6-g1a-option3-static-lens-worker.md: 2 sites — same nuance: deferred work is consumer-wiring, NOT a separate carrier. 4. r3-pr-e8-w1-producer-contract-test-plan-worker.md: 1 site — fold-over-Dag reframe. Receipt of pass-by-construction: this PR adds NO new .dag declaration to src/v3/std/.

Fixes: 1. Delete docs/briefs/r3-substrate-s5-variant-aware-projection-carrier-canvas.md (superseded by the γ-ratified worker brief in same PR; would otherwise leave two current-looking S5 status authorities post-merge — one saying ratification pending, one saying γ ratified). 2. Substrate observation #3 (tag_field String/FieldRef asymmetry) now carries a binding named dissolution trigger: when FieldRef exists as top-level carrier AND InputFieldRef is classified, migrate InternallyTaggedObject.tag_field via follow-on Substrate hygiene PR. Worker MUST add debt-paydown row to authoritative debt ledger before merging carrier-introduction PR. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): Q-Reification row — fix invariant cite (C-1 → P2) cursor review at gunbc#2079 #issuecomment-... flagged C-1 as mis-keyed: INVARIANTS.md C-1 is "missing args fail closed; no LitNull sentinels" (P3 fail-closed family), not parallel-representation/duplicate-authority. The correct cite for rejecting a parallel ReflectedProgram<T> alongside Dag is P2 single authority (INVARIANTS.md line 148: cost of change is proportional to how many files encode the same fact). Cite updated to "INVARIANTS.md P2 single authority" with inline gloss. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): S5 — name dissolution trigger for DeclarationRef alias debt openai-pro REQUEST_CHANGES at gunbc#2079: substrate observation #1 had desired endpoint ("future structural promotion of DeclarationRef") but no checkable dissolution trigger — same P5 gap that #3 (tag_field asymmetry) had been fixed for in commit 2601d7d. Trigger now binding: promote DeclarationRef when EITHER (a) audit-row #14 (declaration_name_preference_rank / declaration_by_name rank-table) closes — dsl/std ↔ src/v3/std module convergence makes name-keyed identity unambiguous and structural module identity available, OR (b) any DeclarationRef-typed consumer surfaces a string-identity bridge per feedback_opaque_strings_attract_heuristics (heuristic patching, naming- convention dispatch, suffix/prefix matching). Worker MUST add debt-paydown row before merging carrier-introduction PR (same pattern as the tag_field debt requirement). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: complete Q-Reification stale-cite sweep — e6-g1a brief :169 + Q-PAFS row codex BLOCKING at gunbc#2079: docs/briefs/r3-pr-e6-g1a-option3-static-lens-worker.md:169 still said TC1/V1 "waits for Q-Reification and the carrier landing", contradicting the same brief's lines 15-19 + 148-153 saying Dag IS the carrier and no separate carrier lands. Fixed: 1. e6-g1a brief line 167-170 paragraph: clarified V1 waits for consumer-wiring work (lens fold consuming Dag via .dag body authority through Evaluator), NOT for a carrier-introduction. 2. r3-program-plan.md:954 Q-PAFS row text was the same shape: "Resume after Q-Reification + ReflectedProgram<T>" — contradicted my new Q-Reification row in the same diff. Updated: Q-Reification STOP CLEARED 2026-05-07 (Option A); remaining hold = Branch B η non-vacuity only. Out-of-scope-for-this-PR: docs/briefs/r3-pr-e6-g1a-option3-feasibility-probe.md contains 4 stale cites but is not modified in this PR; stale-on-main can be swept in a follow-up if needed (single source of truth is the e6-g1a-static-lens worker brief, not the feasibility probe per Q-PAFS Path A acceptance). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): S5 — fix InputFieldRef mis-read; reframe observations #2 + #3 codex BLOCKING at gunbc#2079 line 22: my brief mis-read services.dag:28-36. The text actually says "No separate InputFieldRef carrier is introduced here, since ParamToken.name already carries the same shape and adding a wrapper would duplicate without strengthening the structural invariant" — i.e., InputFieldRef does NOT exist; the comment REJECTS the wrapper. Fixes: 1. Substrate observation #2 reframed: no FieldRef-shaped carrier exists at HEAD; services.dag:28-36 precedent argues against wrapper unless it strengthens structural invariant. New (a)/(b) STOP-and-PING: (a) follow services.dag precedent — wire_tag_field: String + key invariant on wire_tag_values + fixture-load fail-closed check; (b) introduce typed FieldRef — must justify per "duplicate without strengthening" test. 2. Carrier shape (line 19): wire_tag_field: FieldRef → {String|FieldRef} pending observation #2 resolution. 3. Substrate observation #3 reframed: InternallyTaggedObject asymmetry is conditional on path (b); under path (a) no asymmetry exists. Trigger correspondingly conditional. Removed stale "InputFieldRef classified" trigger clause. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): S5 — consolidate split per-variant maps into single keyed entry openai-pro REQUEST_CHANGES at gunbc#2079: CoproductProjection shape split per-variant data across two parallel maps (variant_field_projections + wire_tag_values), admitting illegal states where keysets drift (P2 boundary discipline / illegal-states-unrepresentable). Fix: introduce CoproductVariantProjection { field_projection, wire_tag_value } as the per-variant keyed value; CoproductProjection.variant_projections becomes Map<VariantId, CoproductVariantProjection>. Single keyed authority per variant. Director's binding constraint #2 enumerated the two fields separately but said "refine in implementation as ergonomics demand" — consolidation preserves the substantive constraints (typed WireTagValue leaf, structural per-variant projection) while enforcing keyset alignment by carrier shape. Empty-payload variants encoded via FieldProjection::Empty constructor (or analog), not via map-absence. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): S5 — fix stale split-map vocab in path (a) + scope STOP-and-PING umbrella openai-pro REQUEST_CHANGES at gunbc#2079: 2 BLOCKING findings. 1. Path (a) at line 43 still referenced "Map<VariantId, WireTagValue> key invariant on wire_tag_values" — that's the superseded split-map vocab; the consolidated shape is Map<VariantId, CoproductVariantProjection> on variant_projections. Path (a) now references the consolidated map; per-variant WireTagValue lives inside CoproductVariantProjection. 2. Pre-ratification umbrella at line 36 said "all 3 dispositions pre-ratified, proceed without re-pinging" — but observation #2 was re-opened after the codex InputFieldRef finding and explicitly says STOP-and-PING. Contradictory. Umbrella now scoped: observations #1 + #3 are pre-ratified; #2 is re-opened STOP-and-PING — worker MUST escalate before choosing path (a) vs (b). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): descent_execution_proof canvas — 4-residual coproduct-dissolution audit Director ratified split disposition at gunbc#828 #issuecomment-4394696074: descent_execution_proof STANDS ALONE (consumer-side termination-contract substrate function with fail-closed residual enumeration; folding into T-E-P-Producer-Broadening explicitly rejected — different concern axis). Canvas surfaces 3 carrier-shape options for the residual enumeration per Director's coproduct-dissolution audit suggestion: α: 4-variant coproduct verbatim from §10.3 row 966 (Missing | Unknown | Incomplete | NonStrict) β: 3-axis dimensional product (presence × completeness × strictness) γ (recommended): reuse DescentEvidence at termination.dag:14-17 for "absent/unknown" via EvidenceUnknown(DescentEvidence) payload-variant + separate EvidenceIncomplete — ratchets variant count 4 → 2 via dimensional folding while honoring services.dag "no parallel wrapper" precedent. Mgr recommendation γ; β rejected unless 3 axes provably compose orthogonally. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): SourceSpan brief Row #6 — derive from bootstrap_authority map, no new enum variant codex BLOCKING (post-merge of #2079, on commit 85ceb85 — same brief is now on main): my Row #6 disposition told the worker to introduce a new BootstrapAuthority::Pipeline variant ("extend the enum if needed"). That violates P2 single-authority — src/v3/std/bootstrap_authority.dag:90 already has "src/v3/compiler/pipeline.dag": CompilerAuthority, classifying pipeline.dag under the existing CompilerAuthority variant. The :14-17 comment is explicit: "the path itself is the BootstrapAuthoritySet map key; variants carry no duplicate path payload" — single authority, not extension-by-variant. Fix: Row #6 now instructs worker to derive the typed key from the existing bootstrap_authority-map witness (BootstrapAuthorityKey threading the existing CompilerAuthority classifier), refining the constructor surface if needed — NOT introducing a new enum variant. STOP-and-PING criteria updated to forbid new-variant resolution under any path.

BLOCKING (LAYER MODEL / illegal states unrepresentable): worker brief shape `EvidenceUnknown(DescentEvidence)` admitted EvidenceUnknown(Strict) even though the canvas itself acknowledged Strict-isn't-a-residual as illegal. P2 requires API-level enforcement, not prose convention. Fix: introduce typed subset `NonStrictEvidence = NonIncreasing | DescentUnknown`; residual now `EvidenceUnknown(NonStrictEvidence)` — illegal-states-unrepresentable by construction. NonStrictEvidence lands in same file as DescentResidual; composes with existing 3-variant DescentEvidence via inhabitation, not re-definition. 2. NON-BLOCKING (live-state drift): canvas + worker brief both visible with "ratification needed" vs "ratified" status — same P2 single-authority shape as the S5 canvas/worker-brief co-existence at #2079. Fix: delete docs/briefs/r3-substrate-descent-execution-proof-canvas.md (worker brief frontmatter already names it as superseded; with canvas gone the live authority is unambiguous).

Reviewer's "no such section" claim is wrong on substance (file + section + row all exist) but the line drift IS real. Fix per feedback_section_anchors_over_line_numbers (Director calibration in gunbc#2079): replaced all "§10.3 row 966" with "§10.3 Q-EVAL-Descent- Termination-Contract row" — name-anchor instead of line-anchor, drift-immune. 5 occurrences cleaned (closure predicate, acceptance gate #3, gate #5, STOP criterion, worker pin justification).

Net-finding §3 updated with grep result inline + "N=1 empirically grounded" framing replacing speculative "secondary candidate" language. Empirical basis for DEFERRED β-extended disposition strengthened. Concern 2 (Option (ii) multiplier framing): per-target lens instances replicate the entire Lens<C> authoring surface — N×M × 4 (carrier + monoid sequential + branch + iterate) authoring overhead. Updated Con bullet to reflect the multiplier explicitly: 3 targets × 1 cost lens × 4 = 12 authored fns; grows to 36 if 3 lenses need target-context. Cites feedback_parallel_representation_debt as the P2 framing. Concern 3 (Option (i) threading cost quantification): replaced narrative "threading cost is real but manageable" with quantified breakdown — ~15 signature changes + 14 ignore-parameter patterns + 1 consumer + cementing- test revalidation.

That violates P2 single-authority — src/v3/std/bootstrap_authority.dag:90 already has "src/v3/compiler/pipeline.dag": CompilerAuthority, classifying pipeline.dag under the existing CompilerAuthority variant. The :14-17 comment is explicit: "the path itself is the BootstrapAuthoritySet map key; variants carry no duplicate path payload" — single authority, not extension-by-variant. Fix: Row #6 now instructs worker to derive the typed key from the existing bootstrap_authority-map witness (BootstrapAuthorityKey threading the existing CompilerAuthority classifier), refining the constructor surface if needed — NOT introducing a new enum variant. STOP-and-PING criteria updated to forbid new-variant resolution under any path.

BLOCKING (LAYER MODEL / illegal states unrepresentable): worker brief shape `EvidenceUnknown(DescentEvidence)` admitted EvidenceUnknown(Strict) even though the canvas itself acknowledged Strict-isn't-a-residual as illegal. P2 requires API-level enforcement, not prose convention. Fix: introduce typed subset `NonStrictEvidence = NonIncreasing | DescentUnknown`; residual now `EvidenceUnknown(NonStrictEvidence)` — illegal-states-unrepresentable by construction. NonStrictEvidence lands in same file as DescentResidual; composes with existing 3-variant DescentEvidence via inhabitation, not re-definition. 2. NON-BLOCKING (live-state drift): canvas + worker brief both visible with "ratification needed" vs "ratified" status — same P2 single-authority shape as the S5 canvas/worker-brief co-existence at #2079. Fix: delete docs/briefs/r3-substrate-descent-execution-proof-canvas.md (worker brief frontmatter already names it as superseded; with canvas gone the live authority is unambiguous).

Same shape of error as 3 prior BLOCKING reversals (Q-Reification, S5 DeclarationRef, T-CostLens merge-content).

Net-finding §3 updated with grep result inline + "N=1 empirically grounded" framing replacing speculative "secondary candidate" language. Empirical basis for DEFERRED β-extended disposition strengthened. Concern 2 (Option (ii) multiplier framing): per-target lens instances replicate the entire Lens<C> authoring surface — N×M × 4 (carrier + monoid sequential + branch + iterate) authoring overhead. Updated Con bullet to reflect the multiplier explicitly: 3 targets × 1 cost lens × 4 = 12 authored fns; grows to 36 if 3 lenses need target-context. Cites feedback_parallel_representation_debt as the P2 framing. Concern 3 (Option (i) threading cost quantification): replaced narrative "threading cost is real but manageable" with quantified breakdown — ~15 signature changes + 14 ignore-parameter patterns + 1 consumer + cementing- test revalidation.

ReflectedProgram<T> rejected. Gate A patches: 1. r3-program-plan.md §10.3: new Q-Reification row marked RATIFIED with PR #2096 merge link + Gate A receipt scope (this PR + #1960 closed-as-non-addition). 2. r3-v-pattern-a-tc1-v1-worker.md: 3 sites — status header (Q-Reification CLEARED, Branch B η non-vacuity remains), worker-pin gate, E6-G1.a/E3 producer dependency. Replaces ReflectedProgram<T> with consumer-wiring nuance: lens fold consumes Dag via .dag body authority through Evaluator. 3. r3-pr-e6-g1a-option3-static-lens-worker.md: 2 sites — same nuance: deferred work is consumer-wiring, NOT a separate carrier. 4. r3-pr-e8-w1-producer-contract-test-plan-worker.md: 1 site — fold-over-Dag reframe. Receipt of pass-by-construction: this PR adds NO new .dag declaration to src/v3/std/.

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

The correct cite for rejecting a parallel ReflectedProgram<T> alongside Dag is P2 single authority (INVARIANTS.md line 148: cost of change is proportional to how many files encode the same fact).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): S5 — name dissolution trigger for DeclarationRef alias debt openai-pro REQUEST_CHANGES at gunbc#2079: substrate observation #1 had desired endpoint ("future structural promotion of DeclarationRef") but no checkable dissolution trigger — same P5 gap that #3 (tag_field asymmetry) had been fixed for in commit 2601d7d. Trigger now binding: promote DeclarationRef when EITHER (a) audit-row #14 (declaration_name_preference_rank / declaration_by_name rank-table) closes — dsl/std ↔ src/v3/std module convergence makes name-keyed identity unambiguous and structural module identity available, OR (b) any DeclarationRef-typed consumer surfaces a string-identity bridge per feedback_opaque_strings_attract_heuristics (heuristic patching, naming- convention dispatch, suffix/prefix matching). Worker MUST add debt-paydown row before merging carrier-introduction PR (same pattern as the tag_field debt requirement).

Fixed: 1. e6-g1a brief line 167-170 paragraph: clarified V1 waits for consumer-wiring work (lens fold consuming Dag via .dag body authority through Evaluator), NOT for a carrier-introduction. 2. r3-program-plan.md:954 Q-PAFS row text was the same shape: "Resume after Q-Reification + ReflectedProgram<T>" — contradicted my new Q-Reification row in the same diff. Updated: Q-Reification STOP CLEARED 2026-05-07 (Option A); remaining hold = Branch B η non-vacuity only. Out-of-scope-for-this-PR: docs/briefs/r3-pr-e6-g1a-option3-feasibility-probe.md contains 4 stale cites but is not modified in this PR; stale-on-main can be swept in a follow-up if needed (single source of truth is the e6-g1a-static-lens worker brief, not the feasibility probe per Q-PAFS Path A acceptance).

The text actually says "No separate InputFieldRef carrier is introduced here, since ParamToken.name already carries the same shape and adding a wrapper would duplicate without strengthening the structural invariant" — i.e., InputFieldRef does NOT exist; the comment REJECTS the wrapper. Fixes: 1. Substrate observation #2 reframed: no FieldRef-shaped carrier exists at HEAD; services.dag:28-36 precedent argues against wrapper unless it strengthens structural invariant. New (a)/(b) STOP-and-PING: (a) follow services.dag precedent — wire_tag_field: String + key invariant on wire_tag_values + fixture-load fail-closed check; (b) introduce typed FieldRef — must justify per "duplicate without strengthening" test. 2. Carrier shape (line 19): wire_tag_field: FieldRef → {String|FieldRef} pending observation #2 resolution. 3. Substrate observation #3 reframed: InternallyTaggedObject asymmetry is conditional on path (b); under path (a) no asymmetry exists. Trigger correspondingly conditional. Removed stale "InputFieldRef classified" trigger clause. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): S5 — consolidate split per-variant maps into single keyed entry openai-pro REQUEST_CHANGES at gunbc#2079: CoproductProjection shape split per-variant data across two parallel maps (variant_field_projections + wire_tag_values), admitting illegal states where keysets drift (P2 boundary discipline / illegal-states-unrepresentable). Fix: introduce CoproductVariantProjection { field_projection, wire_tag_value } as the per-variant keyed value; CoproductProjection.variant_projections becomes Map<VariantId, CoproductVariantProjection>. Single keyed authority per variant. Director's binding constraint #2 enumerated the two fields separately but said "refine in implementation as ergonomics demand" — consolidation preserves the substantive constraints (typed WireTagValue leaf, structural per-variant projection) while enforcing keyset alignment by carrier shape. Empty-payload variants encoded via FieldProjection::Empty constructor (or analog), not via map-absence. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): S5 — fix stale split-map vocab in path (a) + scope STOP-and-PING umbrella openai-pro REQUEST_CHANGES at gunbc#2079: 2 BLOCKING findings. 1. Path (a) at line 43 still referenced "Map<VariantId, WireTagValue> key invariant on wire_tag_values" — that's the superseded split-map vocab; the consolidated shape is Map<VariantId, CoproductVariantProjection> on variant_projections. Path (a) now references the consolidated map; per-variant WireTagValue lives inside CoproductVariantProjection. 2. Pre-ratification umbrella at line 36 said "all 3 dispositions pre-ratified, proceed without re-pinging" — but observation #2 was re-opened after the codex InputFieldRef finding and explicitly says STOP-and-PING. Contradictory. Umbrella now scoped: observations #1 + #3 are pre-ratified; #2 is re-opened STOP-and-PING — worker MUST escalate before choosing path (a) vs (b).

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

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): SourceSpan brief Row #6 — derive from bootstrap_authority map, no new enum variant codex BLOCKING (post-merge of #2079, on commit 85ceb85 — same brief is now on main): my Row #6 disposition told the worker to introduce a new BootstrapAuthority::Pipeline variant ("extend the enum if needed"). That violates P2 single-authority — src/v3/std/bootstrap_authority.dag:90 already has "src/v3/compiler/pipeline.dag": CompilerAuthority, classifying pipeline.dag under the existing CompilerAuthority variant. The :14-17 comment is explicit: "the path itself is the BootstrapAuthoritySet map key; variants carry no duplicate path payload" — single authority, not extension-by-variant. Fix: Row #6 now instructs worker to derive the typed key from the existing bootstrap_authority-map witness (BootstrapAuthorityKey threading the existing CompilerAuthority classifier), refining the constructor surface if needed — NOT introducing a new enum variant. STOP-and-PING criteria updated to forbid new-variant resolution under any path.

BLOCKING (LAYER MODEL / illegal states unrepresentable): worker brief shape `EvidenceUnknown(DescentEvidence)` admitted EvidenceUnknown(Strict) even though the canvas itself acknowledged Strict-isn't-a-residual as illegal. P2 requires API-level enforcement, not prose convention. Fix: introduce typed subset `NonStrictEvidence = NonIncreasing | DescentUnknown`; residual now `EvidenceUnknown(NonStrictEvidence)` — illegal-states-unrepresentable by construction. NonStrictEvidence lands in same file as DescentResidual; composes with existing 3-variant DescentEvidence via inhabitation, not re-definition. 2. NON-BLOCKING (live-state drift): canvas + worker brief both visible with "ratification needed" vs "ratified" status — same P2 single-authority shape as the S5 canvas/worker-brief co-existence at #2079. Fix: delete docs/briefs/r3-substrate-descent-execution-proof-canvas.md (worker brief frontmatter already names it as superseded; with canvas gone the live authority is unambiguous).

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

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(proposals): Q-Lens-Target-Context — absorb PM canvas-review concerns 1-3 Director relayed PM canvas review at #2068 c#4401627536: Concern 1 (RESOLVED via grep-verify): empirical N=1 confirmation. PM ran `grep -lc 'TypeRealization|CallableRealization|MethodTemplateContract| target_realization|realization_cost|LanguageSpec' src/v3/lenses/*.dag`; only cost.dag has 3 hits, all 14 others have 0 refs (including emission_provenance.dag which I'd previously framed speculatively). Net-finding §3 updated with grep result inline + "N=1 empirically grounded" framing replacing speculative "secondary candidate" language. Empirical basis for DEFERRED β-extended disposition strengthened. Concern 2 (Option (ii) multiplier framing): per-target lens instances replicate the entire Lens<C> authoring surface — N×M × 4 (carrier + monoid sequential + branch + iterate) authoring overhead. Updated Con bullet to reflect the multiplier explicitly: 3 targets × 1 cost lens × 4 = 12 authored fns; grows to 36 if 3 lenses need target-context. Cites feedback_parallel_representation_debt as the P2 framing. Concern 3 (Option (i) threading cost quantification): replaced narrative "threading cost is real but manageable" with quantified breakdown — ~15 signature changes + 14 ignore-parameter patterns + 1 consumer + cementing- test revalidation. Helps future Director ratification at N=2 trigger event. All 3 amendments are docs-only refinements; ε ratification at gunbc#2181 c#4401584012 unchanged. Strengthens canvas as durable substrate-shape decision record. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(proposals): canvases — collapse stale ratification-ask sections post-ratification codex BLOCKING at #2181 (sha be9a9c9): both canvases had stale "Director ratification ask" sections after status headers were updated to RATIFIED/DEFERRED. Per INVARIANTS P1 "Documentation Describes Live State" — canvas internally presented both settled and unsettled authority. Fixes: 1. Q-Cost-Composition-Layering line 69-76: "Director ratification ask" section collapsed to "Director ratification (RECEIVED 2026-05-07)" with ε ratified, β-extended deferred, "both sequenced" rejected. Three options recorded as historical with ratification cite. Eliminates the rejected "both, sequenced" line that conflicted with status-header "canonical-not- transitional" framing. 2. Q-Lens-Target-Context line 131-136: "Director ratification ask" section collapsed to "Director disposition (DEFERRED 2026-05-07; reopens on N=2 trigger event)". Original ratification asks recorded as FROZEN; revisit at N=2 trigger event with then-current substrate-state grep. Eliminates live-now-ratify framing that conflicted with status-header DEFERRED. Both canvases now single live authority — RATIFIED/DEFERRED dispositions, no internal ratification-ask drift. Future re-ratification (Q-Lens-Target- Context at N=2 trigger) refreshes options matrix at that point per substrate-state-honesty discipline.

Per P1 Documentation Describes Live State + P2 single-authority metadata: the live count at HEAD is `cost × 3 targets = 3 per-target instances` (× 4 authoring-multiplier per Option (ii) Con = 12 fns). The `emission_provenance × 3` figure is a reopen-only future scenario that materializes only if emission_provenance becomes the second real target-context lens at producer- wiring landing time. Updated to separate the two clearly: live count + reopen-only future scenario marked separately. Aligns with the grep-verified N=1 finding established earlier in canvas §3.

The text actually says "No separate InputFieldRef carrier is introduced here, since ParamToken.name already carries the same shape and adding a wrapper would duplicate without strengthening the structural invariant" — i.e., InputFieldRef does NOT exist; the comment REJECTS the wrapper. Fixes: 1. Substrate observation #2 reframed: no FieldRef-shaped carrier exists at HEAD; services.dag:28-36 precedent argues against wrapper unless it strengthens structural invariant. New (a)/(b) STOP-and-PING: (a) follow services.dag precedent — wire_tag_field: String + key invariant on wire_tag_values + fixture-load fail-closed check; (b) introduce typed FieldRef — must justify per "duplicate without strengthening" test. 2. Carrier shape (line 19): wire_tag_field: FieldRef → {String|FieldRef} pending observation #2 resolution. 3.

Fix: introduce CoproductVariantProjection { field_projection, wire_tag_value } as the per-variant keyed value; CoproductProjection.variant_projections becomes Map<VariantId, CoproductVariantProjection>. Single keyed authority per variant. Director's binding constraint #2 enumerated the two fields separately but said "refine in implementation as ergonomics demand" — consolidation preserves the substantive constraints (typed WireTagValue leaf, structural per-variant projection) while enforcing keyset alignment by carrier shape. Empty-payload variants encoded via FieldProjection::Empty constructor (or analog), not via map-absence.

Path (a) now references the consolidated map; per-variant WireTagValue lives inside CoproductVariantProjection. 2. Pre-ratification umbrella at line 36 said "all 3 dispositions pre-ratified, proceed without re-pinging" — but observation #2 was re-opened after the codex InputFieldRef finding and explicitly says STOP-and-PING.

Same shape of error as 3 prior BLOCKING reversals (Q-Reification, S5 DeclarationRef, T-CostLens merge-content).

PM ran `grep -lc 'TypeRealization|CallableRealization|MethodTemplateContract| target_realization|realization_cost|LanguageSpec' src/v3/lenses/*.dag`; only cost.dag has 3 hits, all 14 others have 0 refs (including emission_provenance.dag which I'd previously framed speculatively). Net-finding §3 updated with grep result inline + "N=1 empirically grounded" framing replacing speculative "secondary candidate" language. Empirical basis for DEFERRED β-extended disposition strengthened. Concern 2 (Option (ii) multiplier framing): per-target lens instances replicate the entire Lens<C> authoring surface — N×M × 4 (carrier + monoid sequential + branch + iterate) authoring overhead. Updated Con bullet to reflect the multiplier explicitly: 3 targets × 1 cost lens × 4 = 12 authored fns; grows to 36 if 3 lenses need target-context. Cites feedback_parallel_representation_debt as the P2 framing. Concern 3 (Option (i) threading cost quantification): replaced narrative "threading cost is real but manageable" with quantified breakdown — ~15 signature changes + 14 ignore-parameter patterns + 1 consumer + cementing- test revalidation.

Per P1 Documentation Describes Live State + P2 single-authority metadata: the live count at HEAD is `cost × 3 targets = 3 per-target instances` (× 4 authoring-multiplier per Option (ii) Con = 12 fns). The `emission_provenance × 3` figure is a reopen-only future scenario that materializes only if emission_provenance becomes the second real target-context lens at producer- wiring landing time. Updated to separate the two clearly: live count + reopen-only future scenario marked separately. Aligns with the grep-verified N=1 finding established earlier in canvas §3.

Fixed: 1. e6-g1a brief line 167-170 paragraph: clarified V1 waits for consumer-wiring work (lens fold consuming Dag via .dag body authority through Evaluator), NOT for a carrier-introduction. 2. r3-program-plan.md:954 Q-PAFS row text was the same shape: "Resume after Q-Reification + ReflectedProgram<T>" — contradicted my new Q-Reification row in the same diff.

The text actually says "No separate InputFieldRef carrier is introduced here, since ParamToken.name already carries the same shape and adding a wrapper would duplicate without strengthening the structural invariant" — i.e., InputFieldRef does NOT exist; the comment REJECTS the wrapper. Fixes: 1. Substrate observation #2 reframed: no FieldRef-shaped carrier exists at HEAD; services.dag:28-36 precedent argues against wrapper unless it strengthens structural invariant. New (a)/(b) STOP-and-PING: (a) follow services.dag precedent — wire_tag_field: String + key invariant on wire_tag_values + fixture-load fail-closed check; (b) introduce typed FieldRef — must justify per "duplicate without strengthening" test. 2. Carrier shape (line 19): wire_tag_field: FieldRef → {String|FieldRef} pending observation #2 resolution. 3. Substrate observation #3 reframed: InternallyTaggedObject asymmetry is conditional on path (b); under path (a) no asymmetry exists. Trigger correspondingly conditional.

Fix: introduce CoproductVariantProjection { field_projection, wire_tag_value } as the per-variant keyed value; CoproductProjection.variant_projections becomes Map<VariantId, CoproductVariantProjection>. Single keyed authority per variant. Director's binding constraint #2 enumerated the two fields separately but said "refine in implementation as ergonomics demand" — consolidation preserves the substantive constraints (typed WireTagValue leaf, structural per-variant projection) while enforcing keyset alignment by carrier shape. Empty-payload variants encoded via FieldProjection::Empty constructor (or analog), not via map-absence.

Path (a) now references the consolidated map; per-variant WireTagValue lives inside CoproductVariantProjection. 2. Pre-ratification umbrella at line 36 said "all 3 dispositions pre-ratified, proceed without re-pinging" — but observation #2 was re-opened after the codex InputFieldRef finding and explicitly says STOP-and-PING.

That violates P2 single-authority — src/v3/std/bootstrap_authority.dag:90 already has "src/v3/compiler/pipeline.dag": CompilerAuthority, classifying pipeline.dag under the existing CompilerAuthority variant.

P2 requires API-level enforcement, not prose convention.

NonStrictEvidence lands in same file as DescentResidual; composes with existing 3-variant DescentEvidence via inhabitation, not re-definition. 2.

Updated to separate the two clearly: live count + reopen-only future scenario marked separately. Aligns with the grep-verified N=1 finding established earlier in canvas §3.

The text actually says "No separate InputFieldRef carrier is introduced here, since ParamToken.name already carries the same shape and adding a wrapper would duplicate without strengthening the structural invariant" — i.e., InputFieldRef does NOT exist; the comment REJECTS the wrapper. Fixes: 1. Substrate observation #2 reframed: no FieldRef-shaped carrier exists at HEAD; services.dag:28-36 precedent argues against wrapper unless it strengthens structural invariant. New (a)/(b) STOP-and-PING: (a) follow services.dag precedent — wire_tag_field: String + key invariant on wire_tag_values + fixture-load fail-closed check; (b) introduce typed FieldRef — must justify per "duplicate without strengthening" test. 2.

Fix: introduce CoproductVariantProjection { field_projection, wire_tag_value } as the per-variant keyed value; CoproductProjection.variant_projections becomes Map<VariantId, CoproductVariantProjection>. Single keyed authority per variant. Director's binding constraint #2 enumerated the two fields separately but said "refine in implementation as ergonomics demand" — consolidation preserves the substantive constraints (typed WireTagValue leaf, structural per-variant projection) while enforcing keyset alignment by carrier shape. Empty-payload variants encoded via FieldProjection::Empty constructor (or analog), not via map-absence.

Path (a) now references the consolidated map; per-variant WireTagValue lives inside CoproductVariantProjection. 2. Pre-ratification umbrella at line 36 said "all 3 dispositions pre-ratified, proceed without re-pinging" — but observation #2 was re-opened after the codex InputFieldRef finding and explicitly says STOP-and-PING.

Same shape of error as 3 prior BLOCKING reversals (Q-Reification, S5 DeclarationRef, T-CostLens merge-content).

Lens does NOT currently read target-context inside fold; producer-side instrumentation records target-specific entries consumed via standard framework.

PM ran `grep -lc 'TypeRealization|CallableRealization|MethodTemplateContract| target_realization|realization_cost|LanguageSpec' src/v3/lenses/*.dag`; only cost.dag has 3 hits, all 14 others have 0 refs (including emission_provenance.dag which I'd previously framed speculatively). Net-finding §3 updated with grep result inline + "N=1 empirically grounded" framing replacing speculative "secondary candidate" language. Empirical basis for DEFERRED β-extended disposition strengthened. Concern 2 (Option (ii) multiplier framing): per-target lens instances replicate the entire Lens<C> authoring surface — N×M × 4 (carrier + monoid sequential + branch + iterate) authoring overhead. Updated Con bullet to reflect the multiplier explicitly: 3 targets × 1 cost lens × 4 = 12 authored fns; grows to 36 if 3 lenses need target-context. Cites feedback_parallel_representation_debt as the P2 framing. Concern 3 (Option (i) threading cost quantification): replaced narrative "threading cost is real but manageable" with quantified breakdown — ~15 signature changes + 14 ignore-parameter patterns + 1 consumer + cementing- test revalidation. Helps future Director ratification at N=2 trigger event. All 3 amendments are docs-only refinements; ε ratification at gunbc#2181 c#4401584012 unchanged.

Per P1 Documentation Describes Live State + P2 single-authority metadata: the live count at HEAD is `cost × 3 targets = 3 per-target instances` (× 4 authoring-multiplier per Option (ii) Con = 12 fns). The `emission_provenance × 3` figure is a reopen-only future scenario that materializes only if emission_provenance becomes the second real target-context lens at producer- wiring landing time. Updated to separate the two clearly: live count + reopen-only future scenario marked separately. Aligns with the grep-verified N=1 finding established earlier in canvas §3.

New hand-Rust under Director-ratified ε scope authority; mirrors emit/rust_target.rs pattern (which is already in the list). Refs: #2141, #2194, #2181 ratification. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(cost.dag): clarify Slice 1a scope vs multi-slice plan per review Per codex APPROVE_WITH_COMMENTS on PR #2194 sha 6548ccf: the header phrasing "T-CostLens follow-on slice closes #37 + #40 + #70 via Rust-side composition fn + test_runner consumer + demo fixture" overstated this PR's scope — Slice 1a only lands RealizationCostTable infra, not the consumer/runner/fixture. Reframed to clarify it's the multi-slice PLAN (sequenced across separate PRs) that closes the gates, not this single PR. Cites Slice 1a (PR #2194) as the current commit + Slice 1b/2/3 as forthcoming. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(v3): Slice 1a builder smoke test against bootstrap rust.dag Per Mgr disposition at gunbc#2068 c#4402516739: minimal 1a self-test at the boundary (TESTING.md discipline — each slice self-testing at its own boundary rather than relying on downstream slices to validate upstream behavior). Exhaustive variant coverage lives in Slice 1b's parameterized-fold tests. Test asserts: 1. `build_for_language(dag, rust_id)` succeeds against bootstrap dag 2. Resulting table has at least one TypeRealization (non-empty) 3. `type_cost(Int)` returns Some(1) per src/v3/spec/rust.dag `rust_int` row (line ~118: `cost: 1`) A 1a-broken table-builder caught here directly is a much shorter bisect than waiting for Slice 1b regression. Refs: #2141, #2194. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(v3): remove pub Default on RealizationCostTable per BLOCKING review Per gpt-5-5-pro REQUEST_CHANGES on PR #2194 sha 6548ccf (BLOCKING #1 LAYER MODEL): public `Default` derive allowed downstream consumers to construct an empty/ungrounded cost table without going through `build_for_language` (substrate-derived facts could be fabricated; fail-closed-at-substrate-consumer-boundary violated). Removed `Default` derive; replaced internal `Self::default()` call site with private `Self::empty()` initializer (module-private, used only by `build_for_language`). Public construction now goes through the build fn that requires `(Dag, DeclarationId)` inputs. BLOCKING #2 (cost.dag status overstating live behavior) was already addressed in commit 5a89f2f — reviewer was looking at sha 6548ccf which predates that fix. Refs: #2141, #2194. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(v3): drop pub *_count() L-8 lens-surface-gate violations CI v3 job L-8 lens surface gate flagged `pub fn type_count() -> usize` + `callable_count` + `operator_count` + `behavior_count` as collapsing typed carriers to primitives (`pub fn .*-> (usize|bool|i64)` rejected). These methods existed only as test affordances; the smoke test now asserts non-emptiness via the `type_cost(Int) == Some(1)` lookup directly (a successful Some(1) implicitly proves table non-empty + bootstrap row landed). cost lookups (`type_cost`/`callable_cost`/`operator_cost`/`behavior_cost`) return `Option<i64>` which dodges the L-8 regex (the lens-surface gate matches `-> i64` directly, not `-> Option<i64>`). Refs: #2141, #2194. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(v3): fail-closed on no-realization-costs language per BLOCKING review Per gpt-5-5-pro REQUEST_CHANGES on PR #2194 sha 36e63d2 (LAYER MODEL + Fail-Closed BLOCKING): `build_for_language` previously returned `Ok(empty table)` when language_id matched zero realization rows — fabricated-empty-table fail-closed contract violation. Downstream consumers could see "plausible None lookups" instead of typed build failure for bogus / unsupported language ids. Added `BuildError::NoRealizationCostsForLanguage { language: DeclarationId }` variant; post-loop check returns this error if all 4 maps are empty (language id is bogus OR spec has no realization rows authored — both bug-like states). Negative test `build_for_non_language_id_fails_closed` covers the path: passing the `Int` primitive's DeclarationId (not a LanguageSpec) yields `NoRealizationCostsForLanguage` carrying the bogus id back.

Net-finding §3 updated with grep result inline + "N=1 empirically grounded" framing replacing speculative "secondary candidate" language. Empirical basis for DEFERRED β-extended disposition strengthened. Concern 2 (Option (ii) multiplier framing): per-target lens instances replicate the entire Lens<C> authoring surface — N×M × 4 (carrier + monoid sequential + branch + iterate) authoring overhead. Updated Con bullet to reflect the multiplier explicitly: 3 targets × 1 cost lens × 4 = 12 authored fns; grows to 36 if 3 lenses need target-context. Cites feedback_parallel_representation_debt as the P2 framing. Concern 3 (Option (i) threading cost quantification): replaced narrative "threading cost is real but manageable" with quantified breakdown — ~15 signature changes + 14 ignore-parameter patterns + 1 consumer + cementing- test revalidation.

Mgr lean: (b) codegen-generation. Path (a) mirror-parity perpetuates parallel-representation debt; (b) dissolves the dual-taxonomy class by construction (substrate canonical, Rust codegens). Map dup-key gap handled via (ii) Rust-side post-codegen wrapping (substrate stays minimal). Director ratification ask: D1 (b) + D1-followup (ii).

Partial retirement was explicitly rejected 2026-04-29 (Director acceptance #1130 / dispatch #1139). Changes: - Add Ledger-discipline preamble: umbrella row stays Open; receipt updates audit-packet enumeration, NOT bridge_ledger.dag. - Acceptance #3 reframed: do NOT mutate bridge_ledger.dag; mark rows #2 + #6 retired in the audit packet only. - Authority anchor updated: status=Open (not Proposed); add r3-structure.md:115 + bridge_ledger.dag:125-129 line refs. - Cross-Mgr section reframed: umbrella ratchet cannot flip on this PR alone; Verification's ledger-zero audit progress field is post-merge tracking, not a same-slice pre-merge blocker.

Substrate observation #3 (tag_field String/FieldRef asymmetry) now carries a binding named dissolution trigger: when FieldRef exists as top-level carrier AND InputFieldRef is classified, migrate InternallyTaggedObject.tag_field via follow-on Substrate hygiene PR.

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

The text actually says "No separate InputFieldRef carrier is introduced here, since ParamToken.name already carries the same shape and adding a wrapper would duplicate without strengthening the structural invariant" — i.e., InputFieldRef does NOT exist; the comment REJECTS the wrapper. Fixes: 1. Substrate observation #2 reframed: no FieldRef-shaped carrier exists at HEAD; services.dag:28-36 precedent argues against wrapper unless it strengthens structural invariant. New (a)/(b) STOP-and-PING: (a) follow services.dag precedent — wire_tag_field: String + key invariant on wire_tag_values + fixture-load fail-closed check; (b) introduce typed FieldRef — must justify per "duplicate without strengthening" test. 2. Carrier shape (line 19): wire_tag_field: FieldRef → {String|FieldRef} pending observation #2 resolution. 3. Substrate observation #3 reframed: InternallyTaggedObject asymmetry is conditional on path (b); under path (a) no asymmetry exists. Trigger correspondingly conditional.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(briefs): S5 — consolidate split per-variant maps into single keyed entry openai-pro REQUEST_CHANGES at gunbc#2079: CoproductProjection shape split per-variant data across two parallel maps (variant_field_projections + wire_tag_values), admitting illegal states where keysets drift (P2 boundary discipline / illegal-states-unrepresentable). Fix: introduce CoproductVariantProjection { field_projection, wire_tag_value } as the per-variant keyed value; CoproductProjection.variant_projections becomes Map<VariantId, CoproductVariantProjection>. Single keyed authority per variant. Director's binding constraint #2 enumerated the two fields separately but said "refine in implementation as ergonomics demand" — consolidation preserves the substantive constraints (typed WireTagValue leaf, structural per-variant projection) while enforcing keyset alignment by carrier shape. Empty-payload variants encoded via FieldProjection::Empty constructor (or analog), not via map-absence.

Path (a) at line 43 still referenced "Map<VariantId, WireTagValue> key invariant on wire_tag_values" — that's the superseded split-map vocab; the consolidated shape is Map<VariantId, CoproductVariantProjection> on variant_projections. Path (a) now references the consolidated map; per-variant WireTagValue lives inside CoproductVariantProjection. 2. Pre-ratification umbrella at line 36 said "all 3 dispositions pre-ratified, proceed without re-pinging" — but observation #2 was re-opened after the codex InputFieldRef finding and explicitly says STOP-and-PING. Contradictory. Umbrella now scoped: observations #1 + #3 are pre-ratified; #2 is re-opened STOP-and-PING — worker MUST escalate before choosing path (a) vs (b).

That violates P2 single-authority — src/v3/std/bootstrap_authority.dag:90 already has "src/v3/compiler/pipeline.dag": CompilerAuthority, classifying pipeline.dag under the existing CompilerAuthority variant. The :14-17 comment is explicit: "the path itself is the BootstrapAuthoritySet map key; variants carry no duplicate path payload" — single authority, not extension-by-variant. Fix: Row #6 now instructs worker to derive the typed key from the existing bootstrap_authority-map witness (BootstrapAuthorityKey threading the existing CompilerAuthority classifier), refining the constructor surface if needed — NOT introducing a new enum variant.

Same shape of error as 3 prior BLOCKING reversals (Q-Reification, S5 DeclarationRef, T-CostLens merge-content). Substrate-state-grep is being treated as retrospective-correction rather than prerequisite. Tightening: this is the 4th occurrence; should be hard-prerequisite-discipline going forward. Fixes: 1. Q-Lens-Target-Context inventory section: replaced approximate "15+ lens instances" framing with exact `ls`-grep registry (15 .dag files listed by name), notes infer_helpers + lower_helpers are helper modules authoring shared structural fns rather than top-level lens instances. 2. emission_provenance.dag analysis grounded in HEAD file status header: STATUS = STRUCTURALLY TERMINAL; LENS-INSTANCE FIXTURE-BOUND; BEHAVIORALLY DEFERRED. `read` body is fail-closed Empty stub. Lens does NOT currently read target-context inside fold; producer-side instrumentation records target-specific entries consumed via standard framework. Reframed as "ungrounded at HEAD" rather than "POSSIBLY target-context need" — re-evaluates at producer-wiring landing. 3.

PM ran `grep -lc 'TypeRealization|CallableRealization|MethodTemplateContract| target_realization|realization_cost|LanguageSpec' src/v3/lenses/*.dag`; only cost.dag has 3 hits, all 14 others have 0 refs (including emission_provenance.dag which I'd previously framed speculatively). Net-finding §3 updated with grep result inline + "N=1 empirically grounded" framing replacing speculative "secondary candidate" language. Empirical basis for DEFERRED β-extended disposition strengthened. Concern 2 (Option (ii) multiplier framing): per-target lens instances replicate the entire Lens<C> authoring surface — N×M × 4 (carrier + monoid sequential + branch + iterate) authoring overhead. Updated Con bullet to reflect the multiplier explicitly: 3 targets × 1 cost lens × 4 = 12 authored fns; grows to 36 if 3 lenses need target-context. Cites feedback_parallel_representation_debt as the P2 framing. Concern 3 (Option (i) threading cost quantification): replaced narrative "threading cost is real but manageable" with quantified breakdown — ~15 signature changes + 14 ignore-parameter patterns + 1 consumer + cementing- test revalidation. Helps future Director ratification at N=2 trigger event. All 3 amendments are docs-only refinements; ε ratification at gunbc#2181 c#4401584012 unchanged.

Per P1 Documentation Describes Live State + P2 single-authority metadata: the live count at HEAD is `cost × 3 targets = 3 per-target instances` (× 4 authoring-multiplier per Option (ii) Con = 12 fns). The `emission_provenance × 3` figure is a reopen-only future scenario that materializes only if emission_provenance becomes the second real target-context lens at producer- wiring landing time. Updated to separate the two clearly: live count + reopen-only future scenario marked separately. Aligns with the grep-verified N=1 finding established earlier in canvas §3.

Changes: 1. `src/v3/std/substrate.dag` — new `fn declaration_by_name` host fn below `declaration_by_id`; comment refresh at line 54 reflecting accessor now-landed. 2. `src/v3/spec/rust.dag` — `rust_declaration_by_name_accessor` carrier (`({p0}).declaration_by_name(&{p1}).cloned()`) + binding to `rust_language`. Mirrors declaration_by_id_binding_rust shape. 3. **Delete** `src/v3/compiler/src/lens_cost_target_composition.rs` (the 374-line stage0 hand-Rust addition NACK'd by Director at gunbc#828 c#4402795815 for P0 zero-hand-Rust violation). 4.

PM ran `grep -lc 'TypeRealization|CallableRealization|MethodTemplateContract| target_realization|realization_cost|LanguageSpec' src/v3/lenses/*.dag`; only cost.dag has 3 hits, all 14 others have 0 refs (including emission_provenance.dag which I'd previously framed speculatively). Net-finding §3 updated with grep result inline + "N=1 empirically grounded" framing replacing speculative "secondary candidate" language. Empirical basis for DEFERRED β-extended disposition strengthened. Concern 2 (Option (ii) multiplier framing): per-target lens instances replicate the entire Lens<C> authoring surface — N×M × 4 (carrier + monoid sequential + branch + iterate) authoring overhead. Updated Con bullet to reflect the multiplier explicitly: 3 targets × 1 cost lens × 4 = 12 authored fns; grows to 36 if 3 lenses need target-context. Cites feedback_parallel_representation_debt as the P2 framing. Concern 3 (Option (i) threading cost quantification): replaced narrative "threading cost is real but manageable" with quantified breakdown — ~15 signature changes + 14 ignore-parameter patterns + 1 consumer + cementing- test revalidation.

P1 is bridging existing tooling to substrate (compositional-extension), NOT multi-slice greenfield genuinely-novel pattern-5 as originally framed. Smaller scope than canvas-finding-taxonomy pattern 5 implies. Path-call genuinely depends on PB Mgr's R-3 (canonical CI bench host) + R-7 (tier3_baseline.json baseline-capture path) decisions per their audit response at c#4403059897. Path-call DEFERRED to cross-Mgr coordination outcome with PB Mgr (#2074); Substrate Mgr surfaces with corrected framing this turn. Sixth discipline-failure of cycle (mine, second-axis grep gap on existing-tooling state); same-class as Director's first-axis grep gap on consumer-side requirement at the prior turn. Memorialized as two-axis verification discipline anchor. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(proposals): Q-ValueBody-Drift-Resolution canvas — DRAFT (codegen-generation lean) D1 substrate-shape question per Q-ValueBody-Isomorphism RATIFIED at gunb-ai/gunbc#828 c#4403972737. Variant-inventory readiness input from PR #2218 (merged 2026-05-08) confirms drift: Rust 5 variants vs substrate 3 constructors; asymmetry on Scalar+List Rust-only + Map payload-parity-with-semantic-gap. Two-axis verification at HEAD: - Substrate-precedent: codegen tooling exists (regen_bootstrap_emit; 5 _generated.rs files; regen_bootstrap binary). Pattern-3 strict- mirror codegen extension applies; no pattern-5 P1 procedure. - Consumer-side requirement: V1 worker brief explicitly names mirror- parity-vs-codegen-generation as D1 path-pair. Mgr lean: (b) codegen-generation. Path (a) mirror-parity perpetuates parallel-representation debt; (b) dissolves the dual-taxonomy class by construction (substrate canonical, Rust codegens). Map dup-key gap handled via (ii) Rust-side post-codegen wrapping (substrate stays minimal). Director ratification ask: D1 (b) + D1-followup (ii). Carrier slice path post-ratification: extend regen_bootstrap_emit; add Scalar+List constructors to substrate; regen + remove hand-Rust enum; handle Map dup-key per ratified followup. Worker pin fresh-pool per same-window-dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(proposals): Q-ValueBody-Drift-Resolution canvas amend authority cite (codex BLOCKING fix) Director ratified (α) amendment-PR at gunb-ai/gunbc#828 c#4404398425 post-codex-BLOCKING at PR #2222 c#4404360699. Canvas originally cited regen_bootstrap_emit.rs as codegen authority for ValueBody runtime mirror; corrected to scripts/regen_runtime_mirrors.py which is the substrate→Rust runtime-mirror generator (reads substrate.dag, emits dag_scalar_generated.rs etc.). regen_bootstrap_emit.rs is a separate codegen system that generates bootstrap_generated.rs (bootstrap parser/lower compile snapshot). D1 (b) codegen-generation ratification UNCHANGED; only authority-path cites corrected. Carrier slice path at canvas §6-step plan now references correct runtime-mirror generator. Canvas inline notes mark amendment location for future-reader audit trail. 8th cycle-tier framing-failure (Mgr-tier; same fine-granularity gap parallel to Director-tier failure at c#4404256128). Two-axis verification discipline applied at insufficient granularity (verified codegen-tooling- exists but didn't disambiguate against bootstrap-vs-runtime-mirror systems). Discipline anchor refinement: when canvas cites a codegen system / tooling / authority path, identify the SPECIFIC generator/handler for the target-file-class. Don't accept 'tooling exists' at coarse granularity. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: reconcile cross_target_coverage emission_path_projections post-population drift cross_target_coverage.dag:179 + sg0_census_test.rs:355 still described emission_path_projections as `(empty data state)` / `== []`, but the data block at cross_target_coverage.dag:186 is populated with 41 Phase-1 rows (Rust 13 / Python 16 / Go 12). Update both comment sites to reflect the populated state. P1 Modeling Faithfulness — comment-drift only, no behavior change. Surfaced by gentle-newt-665 R3 Debt-Paydown ROADMAP audit at gunb-ai/gunbc#2062; absorbed into Substrate lane (#1939) per L6 emission_path_projections carrier ownership. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix: pad cross_target_coverage.dag comment to preserve byte offsets Previous comment edit changed line 179 length 76→75, shifting SourceSpan byte offsets in bootstrap_generated.rs by 1 and breaking regen_bootstrap --verify in CI. Pad with one extra dash to restore original 76-char length; comment text intent unchanged. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: R3 Substrate Mgr — lane through R3 close * fix(canvas): clarify Source param doesn't carry subject identity (P2) Reviewer flagged on PR #2333 inline review: parametric form WorkflowObservationAnchor<BehaviorId, TimingMeasurement> would create redundant subject-identity authority if TimingMeasurement carries subject identity (P2 violation). Clarify Q-WAD-S2-Anchor (b) so Source parameter is observed-payload-only; subject identity is owned solely by Subject parameter. In worker's actual PR #2360 shape, TimingMeasurement is variant-typed report state (Observed { nanoseconds } | Missing | ...) and does NOT carry subject identity — concern is theoretical there but worth clarifying canvas language for clean Director ratification. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): correct fail-closed analysis for LensEnforcement.violates signature Reviewer flagged BLOCKING on PR #2333 inline review (canvas:90): LensEnforcement.violates signature is (Budget, Budget) -> Bool per src/v3/std/lens_application.dag:100 — does NOT see raw Output. Original canvas claim 'fail-closed: violates = Output != Observed' was structurally wrong. Updated: - (a) clarified: projection step (Output → Budget) must fabricate violating Budget for non-Observed variants (option (a)(i)) OR substrate-extend the violates signature (option (a)(ii)) which is canvas-tier and cascades across all lens consumers. - Added option (c) reflecting worker tidy-raven-610 PR #2360 shape: Output folded into TimingMeasurement carrier directly, Budget projection handles fabrication naturally. Status: shape ratification still pending Director per #828 c#4412018726. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): add 🟢 dissolution classification to TimingObservationOutcome variants Reviewer flagged BLOCKING on PR #2333 inline review (canvas:86): proposed sum has no 🟢/🟡/🔴 dissolution receipt per INVARIANTS P5 / modeling-discipline.md §coproduct dissolution. Worker could land unclassified coproduct. Added 🟢 GREEN (terminal) classification to both option (a) TimingObservationOutcome and option (c) folded TimingMeasurement — four variants exhaust externally-attested observation states; no richer-source-extraction path exists at the workflow-observation boundary. Worker .dag declarations MUST carry the 🟢 marker comment per modeling-discipline.md:132. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): correct Q-WAD-S2-Placement to src/v3/std/ (not dsl/std/) Reviewer flagged BLOCKING on PR #2333 inline review (canvas:108): recommending dsl/std/timing_lens.dag conflicts with src/v3/std/lens.dag:17-21 v3-only-carriers convention. Worker would land substrate in wrong layer. Earlier canvas claim 'T-LBP / T-CostLens / T-LAS lens carriers all live in dsl/std/' was factually wrong — they live in src/v3/std/ and src/v3/lenses/. Corrected to src/v3/std/timing_lens.dag throughout. Worker PR #2360 already placed at correct path; canvas now matches. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): make six gate #55 invariants concrete fields on anchor (P2) Reviewer flagged BLOCKING on PR #2333 inline review (canvas:75): the recommended <Subject, Source> parametric shape only named type params and didn't assign digest/producer/observer/prover/timestamp/run-id/ report-state to a single carrier — gate #55 facts wouldn't flow forward under P2 boundary discipline. Fixed: Q-WAD-S2-Anchor (b) now shows explicit six-invariant field schema as concrete fields (subject/artifact_digest/producer_id/ observer_id/prover_id/attached_at/workflow_run_id/observation_outcome) with Subject + Source as type parameters for variable parts only. Notes worker tidy-raven-610 PR #2360 flat shape is already gate-#55-compliant at the field level; convergence path is adding type parameters to the flat shape (minimal rework). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): correct convergence assessment — invariant 5 split-authority in worker shape Reviewer flagged BLOCKING on PR #2333 inline review (canvas:96): claiming worker's flat anchor shape gate-#55-compliant drops invariant 5 (observation_outcome / report-state) from the anchor. Worker's TimingMeasurement variants carry report-state on the payload, not on the anchor — splits P2 single-authority for invariant 5. Fixed: convergence assessment now correctly identifies 5/6 invariants on anchor + invariant 5 split. Path requires TWO edits not one: (1) add <Subject, Source> type parameters to anchor; (2) add observation_outcome: ObservationOutcome<Source> field to anchor itself. This collapses Q-WAD-S2-Output (c) folded shape back to (a)(i) separate-projection — trade-off documented (single-authority preserved at cost of one extra type). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): reject (a)(i) Budget fabrication per P3/C-8 fail-closed (canvas:118) Reviewer flagged BLOCKING on PR #2333 inline review (canvas:118): recommending projection fabricates violating Budget for non-Observed states violates INVARIANTS P3/C-8 fail-closed discipline — erases typed Missing/Ambiguous/Stale failure evidence into a plausible budget value. Consumers downstream of violates can't distinguish 'budget exceeded by observed value' from 'no observation existed'. Fixed: (a)(i) REJECTED with explicit P3/C-8 rationale. Added (a)(iii) Result-typed projection with auto_violate_on_left bit — smaller substrate change than (ii) full-signature-extension. Director-tier disposition still required for (ii) or (iii); (i) no longer a viable path. Convergence implications for worker PR #2360 + canvas (c) folded shape need re-assessment in next pass — (c) sidesteps the violates signature collision but invariant 5 split-authority (per canvas:96 fix in 960a03f98) means observation_outcome belongs on anchor not payload, which then re-introduces the violates-Output-visibility question via ObservationOutcome typing. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): propagate (a)(i) rejection across all recommendation/status refs Earlier commit 594a4df9c rejected (a)(i) Budget fabrication per P3/C-8 inline review. Updated remaining 3 refs to reflect: - Q-WAD-S2-Anchor convergence trade-off line - Q-WAD-S2-Output recommendation: now (a)(ii)/(a)(iii) pending Director - Q3 (c) Status line: Director call is (a)(ii)/(a)(iii) vs (c) (a)(i) is REJECTED throughout; Director-tier LensEnforcement substrate change unavoidable for fail-closed-correct anchor-side report-state carriage. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): correct invariant-6 claim — fail-closed needs LensEnforcement substrate-extension Reviewer flagged BLOCKING on PR #2333 inline review (canvas:91): claim 'all six invariants concrete fields on anchor' was wrong — invariant 6 (fail-closed) explicitly lives at LensEnforcement.violates layer, not on the anchor. Without Q-WAD-S2-Output (a)(ii)/(a)(iii) substrate- extension landing, gate #55 cannot close on 5/6 — would let consumers attach observation facts without fail-closed evidence (P2/P3 violation). Fixed: clarified 5/6 invariants on anchor + invariant 6 dependency on Director-tier LensEnforcement substrate-extension. Gate #55 closure explicitly cross-linked to canvas:118 escalation thread. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): Output (a) variants wrap Source not TimingMeasurement (P2) Reviewer flagged BLOCKING on PR #2333 inline review (canvas:112): Output (a) Observed{value: TimingMeasurement} would wrap the report-state-bearing TimingMeasurement type, duplicating identity/attestation/report-state with the anchor's invariant 5 authority. Reopens P2 split-authority. Fixed: Observed wraps payload-only Source (e.g., TimingPayload { nanoseconds: Int }), NOT TimingMeasurement. Per Q-WAD-S2-Anchor revised convergence: subject identity / attestation / report-state on anchor; payload carries only observed-value-when-present. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): split gate #55 + canonicalize TimingPayload (parent BLOCKING b526a26f) Reviewer flagged 2 BLOCKING on PR #2333 parent review at sha b526a26f: Finding 1 (gate #55 mixes anchor-fact + fail-closed): added gate #55a/#55b split — #55a = anchor carrier landed (worker scope); #55b = LensEnforcement substrate-extension landed across all lens consumers (canvas-tier separate dispatch, owner: Substrate Mgr). Finding 2 (TimingMeasurement overload): added Naming canonicalization section to Carrier inventory. TimingPayload = observed-value-only; WorkflowObservationAnchor = observation record; ObservationOutcome = report state; TimingObservationSet = lens C (per Q1 ratification). Earlier TimingMeasurement references deprecated. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): rewrite Carrier inventory to reflect Director ratification of worker shape Reviewer flagged BLOCKING on PR #2333 inline review (canvas:35): old carrier inventory still said TimingMeasurement owns subject identity + observer attestation, contradicting revised anchor authority. Same-day Director re-ratification at #828 c#4412301889 reversed the canvas (b) recommendations and ratified worker tidy-raven-610's shape as-shipped: - TimingMeasurement = Observed | Missing | Ambiguous | Stale (carrier-as-report-state; owns invariant 5 via variants) - WorkflowObservationAnchor = timing-specific concrete fields (Q-WAD-S2-Anchor (a) ratified; owns invariants 1-4) - TimingObservationSet = aggregation collection - Lens<TimingMeasurement> per-observation Fixed: rewrote Carrier inventory to reflect Director-ratified shape; explicit invariant ownership (anchor: 1-5; LensEnforcement: 6 via gate #55b separate dispatch). TimingPayload canonicalization (which contradicted Director ratification) removed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(canvas): resolve option (c) Pro/Con contradiction on signature collision Reviewer flagged BLOCKING on PR #2333 inline review (canvas:137): option (c) Pro line said 'avoids violates signature collision entirely' but lines 135/139 routed back to (a)(ii)/(a)(iii) — internal contradiction; fail-closed obligation under P3/C-8 still ambiguous. Fixed: rewrote (c) Pro/Con honestly — Pro = state-space discipline (per Director's ratification reasoning); Con = does NOT sidestep violates signature collision, still requires substrate-extension path. Status updated to reflect Director ratification at #828 c#4412301889: (c) carrier shape ratified for worker scope (#55a); LensEnforcement substrate-extension disposition (#55b) still pending between (a)(ii) and (a)(iii). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(v3): LensEnforcement.auto_violate_on_left for observation-driven lenses Per Director ratification at gunb-ai/gunbc#828 c#4412884371 + re-confirmation at c#4413159089: extend LensEnforcement<Output, Budget> with additive auto_violate_on_left: Bool field for observation-driven lens classes (T-Workflow-As-Data Slice 2 timing-lens et seq.). Substrate semantics: when Output is Result-typed (e.g., Result<Observed, ObservationFailure> for timing), runtime checks the bit before calling project; on Result-Left + bit=true, enforcement violates without fabricating a Budget value at the projection boundary. Preserves typed failure evidence (Missing/Ambiguous/Stale/ Unobserved) per INVARIANTS P3/C-8 fail-closed discipline. Backward-compatible additive: existing structural-static lenses (complexity, cost, T-LAS) set the bit to false; bit is inert when Output is not Result-typed. Updated complexity_enforcement declaration + hand-Rust LensEnforcement struct mirror. Closes §1.8 ledger #55 sub-gate b (LensEnforcement substrate-extension prerequisite for fail-closed-correct enforcement on non-Observed report states); enables T-Workflow-As-Data Slice 2 worker (tidy-raven-610 #2359) to revise PR #2360 against the ratified Result-typed Output shape. Canvas authority: docs/briefs/r3-substrate-t-wad-slice-2-timing-lens-canvas.md §"Question 3 (Q-WAD-S2-Output)" + Gate #55 closure-predicate split. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Revert "feat(v3): LensEnforcement.auto_violate_on_left for observation-driven lenses" This reverts commit 5ec59209d1c561788a4f6f686d8d1f62daf086ef. * fix(canvas): Q-WAD-S2-Anchor recommendation aligned to Director ratification of (a) Reviewer flagged BLOCKING on PR #2333 inline review (canvas:99): canvas still recommended (b) generic anchor after Director ratified (a) timing-specific. Competing WorkflowObservationAnchor authorities = P2 violation. Fixed: Q-WAD-S2-Anchor recommendation rewritten to reflect Director RATIFIED (a) per #828 c#4412301889 + c#4413322671. Mgr-tier preliminary (b) was over-engineered (chased hypothetical second-consumer parameterization). Invariant 5 split-authority concern resolved at LensEnforcement layer per (a)(ii) full-signature extension (Director c#4413284764) — violates pattern-matches Output variants directly, no observation_outcome projection wrapper needed.
