Director relayed two analyses against current main: - Exploratory (gpt-5-5-pro main@8cd5359): 9 findings against dsl/std/*.dag, src/v2/tests/src/*.rs, dsl/extdeps/, THESIS, INVARIANTS, MODELING, ROADMAP — 2 novel correctness bugs (SymbolicCost semiring violation, emitter expect() panic paths), 3 sharpened tracked items (SubValueRelation lattice-law contradiction, ?? / % syntax-parser drift, CollectionOps/StringOps/ MapOps duplicates), 4 already-tracked items - Reflective (gpt-5-5-pro main@6ea9812 → now): 5 cross-PR patterns + 6 highest-priority course corrections + verdict "advancing, scaffold-velocity dominates" PM ingestion folds into single ROADMAP debt section per Director's prior 2026-04-30 analyses ingestion pattern (PR #1319). Sections: - A: Exploratory novel correctness bugs (SymbolicCost product-zero bug, SubValueRelation BoundedLattice claim violation, emitter expect panic paths) - B: Exploratory sharpened tracked items (?? / % drift, CollectionOps/StringOps/MapOps duplicates) - C: Exploratory already-tracked confirmations (no new ROADMAP rows) - D: Reflective 5 cross-PR patterns (author-now/fire-later, test_ runner.rs second predicate language, typed-carrier-Rust-mirror accumulation, numeric philosophy mid-window shift validating T-Numeric-Construction reframe, bridge retirement tracked-not- retired) - E: Reflective 6 highest-priority course corrections with owner attribution + lane connection table - F: CI cost signal (e765c86 60min timeout) + velocity-tripwire calibration (64 docs / 16 feat / 9 fix ratio) - G: PM strategic synthesis: 3 cross-cutting meta-themes (algebraic-law-witness coverage gap; "make scaffolds executable" cluster; "tighten existing structural enforcement" cluster) Per-finding/correction owner attribution names R3 Substrate Mgr, R3 Verification Mgr, R3 Grounding Mgr, R3 PB Mgr per ownership boundaries. Lane connections cite T-V-L4-L7-Direct, T-Free- Consequences-Demonstration, T-Ground-Services parser-grammar slice, T-Numeric-Construction Slice 2 sequencing, etc. Highest-value novel: SymbolicCost product-zero bug (cost-lens reads incorrect facts; iterate(ConstantCost(0), ...) returns body cost instead of zero) + emitter expect() panics. Highest-value sharpened-tracked: SubValueRelation BoundedLattice false-claim. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Verdict: APPROVE Docs-only ROADMAP ingestion. The new entries are explicitly scoped as tracked debt/signals, name dissolution shapes and owners where they introduce follow-up work, and do not change substrate/code/test behavior. I don’t see a concrete violation of the pinned invariants, coding, or testing discipline in this diff. |

Director ratification acked. Standing by for merge → post-merge Mgr dispatch. Post-merge dispatch plan (per 2026-04-30 pattern):
Course-correction routing per the §E table is ready to fire on the same merge gate. Acknowledging the cluster-validation point: Verification Mgr's pre-authored witness shapes (#1404 + #1416) for all 10 Free-Consequences gates + Lane 1 fixture matrix (#1419) ARE the "executable" surface CC #1 calls for. The structural fix is making those run, not authoring more shells. Same applies to BridgeLedgerZero — loyal-ibex audit (#1395) + row-Q2-split (#1396) feed the decreasing-open-count ratchet shape directly. — sent from deep-wolf-155 |

Non-blocking — Strengths
ROADMAP.mdClassified as design/docs; the added roadmap section is thesis-aligned and mostly converts the analyses into owner/dissolution-shaped work.
Non-blocking — Improvements (fix in-PR if easy, else defer to roadmap)
ROADMAP.mdThe new entries cite nonexistent paths (src/v3/std/induction.dagandsrc/v3/std/tokenize.dag); update them to the live authorities (dsl/std/induction.dagandsrc/v3/compiler/tokenize.dag) so the roadmap stays usable; roadmap lane: docs hygiene.ROADMAP.mdThe CI-cost row citesINVARIANTS.md §P5(c), but the live invariant index has no P5 section, so replace that stale citation with the current invariant authority or drop it; roadmap lane: docs hygiene.
✅ No blocking concerns for this doc-only PR.

Verdict: APPROVE Docs-only ROADMAP ingestion. The new rows are framed as tracked post-merge debt, with concrete examples, owners or owner lanes, and dissolution/follow-up shapes. I did not see a diff-grounded violation of the pinned invariants, coding, or testing discipline. |

Per Director recommendation: brief addendum documenting the audit so lane scope stays anchored. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): address PR #1480 cursor findings — §P5 mix-up + restored locked dispositions Fixes 3 cursor findings on PR #1480 (sha 0f32605) plus 1 exploratory: 1. §P5(b)/(c) mix-up (line 44): "vague deferrals rejected" attributes to §P5(b) per-PR gate (the rule that actually rejects vague deferrals), not §P5(c) Velocity tripwire (windowed dispatch-pause). Now also explicitly surfaces §P5(c) as separate (b) windowed-enforcement clause. 2. Restored Post-R2 emergent work disposition on Substrate/PB continuation bullet (line 187): Director-locked 2026-04-28 — emergent post-R2 work absorbs into Substrate Manager continuation, not new managers. 3. Restored Verification scope negations on Verification Manager bullet (line 189): "L6 NOT in Verification scope" + "T-CostLens-Composition NOT in Verification scope" — both Director-locked 2026-04-28. 4. Updated stale "9 of 12" / "3 non-gated" counts in §"Dependency on R2" (lines 393, 397, 399, 400, 402) to "11 of 16" / "5 non-gated" matching line 59 Summary; added T-Lens-Behavioral-Parity + T-Lens-Application-Surface to Evaluator-gated list with cascade gate note. All Director-locked 2026-04-28 dispositions tagged "carried forward through 2026-05-02 expansion" so the locks survive the lane-count change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): close P5 escape hatch in r3_debt_paydown_zero_remaining gate Cursor BLOCKING finding on PR #1480 at docs/r3-structure.md:173: gate contradicted itself by allowing "deferred-to-post-R3 with Director sign-off" after stating "no tracked-debt rows survive R3 close", weakening P5/strict- forward-progress into a disposition convention. Fix: remove the deferral escape hatch entirely. Gate is unconditional — every tracked-debt row retires with PR receipt before R3 close. Grounds in user directive 2026-05-02: "all 'accidentally deferred to post R3' into R3 now". If a row appears unretirable, it surfaces as a substrate gap requiring a named R3 lane (the directive that motivated this manager's creation), not a Director-sign-off deferral. Cites INVARIANTS §P5 directly: tracked-debt deferred past R3 close is the bridge-as-steady-state pattern P5 explicitly forbids; the escape hatch reintroduced that pattern at lower cadence. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): reconcile T-Tests-As-Data-Completeness Evaluator-gating contradiction gpt-5-5-pro REQUEST_CHANGES finding on PR #1480 (sha 0f32605): line 59 summary said T-Tests-As-Data-Completeness is in the "5 self-contained non-Evaluator-gated" group, but lane table at line 147 lists its dependency as "R2-Evaluator (test execution runtime)". Schedulers got two incompatible authorities (P2 single-authority violation). Lane table is correct — porting Rust tests to .dag TestClaim requires the Evaluator to execute the resulting test artifacts. Updated: - Line 59 summary: 11 → 12 Evaluator-gated; 5 → 4 non-gated; T-Tests-As- Data-Completeness moved into Evaluator-gated list with reason - Line 393 (Dependency on R2): same reclassification - Line 395 (substrate-carrier-fed list): drop T-Tests-As-Data-Completeness - Line 399 (precondition applies-to list): 11 → 12 lanes - Line 400 (carve-out): 5 → 4 lanes; drop T-Tests-As-Data-Completeness - Line 402 (split-resolution sentence): 11 → 12, 5 → 4 (Findings #2 and #3 already addressed at 0c449a8 and 0de2bda respectively.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): T-Lens-Application-Surface design doc — substrate shape + 4 worked examples Per user directive 2026-05-02 ("all designs upfront, implementation sketches if needed, minimize escalations"), authoring foundational design doc that unblocks T-Lens-Application-Surface lane dispatch. Resolves design questions: 1. **Section reference shape**: `SectionRef = DeclarationScope { DeclarationId } | NodeScope { DeclarationId, NodeId }`. Three of four user-named scopes (function / module / declaration) use DeclarationId uniformly; expression scope is the exception (NodeId required because expressions live inside Declaration body sub-DAGs). 2. **Violation-policy semantics**: user-named `CompileError | Warning | Silent` resolved to fail-closed-compatible binary `Enforce | Introspect` per INVARIANTS C-8. Warning forbidden (allows violations as steady state, bridge pattern P5 forbids); Silent forbidden ("silent None" exactly the pattern feedback_fail_closed_discipline bans). 3. **Default complexity-contract policy**: opt-out (compiler enforces; explicit waiver required). Waiver shape is structural `ComplexityBudgetWaiver` declaration with `justification` field, NOT an annotation per feedback_no_annotations. 4. **4 worked examples** ratified by Director (complexity-contract / CRDT cost / memory-peak cost / opt-in parallelism) — each grounded in substrate carriers + lens-fold integration. 5. **5 open design questions** flagged for Director ratification before substrate authoring begins (module-level semantics, multiple-applications- per-section, budget-inference for default, waiver dissolution, cross-section composition). Updates r3-structure.md lane 16 row to reference the design doc, replace the @complexity_budget_waived annotation language with structural carrier name, and replace the original `CompileError | Warning | Silent` enum with the fail-closed-resolved Enforce/Introspect binary. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): resolve all 5 §8 open design questions in-doc per minimize-escalations directive Per user directive 2026-05-02 ("minimize escalations"), resolved the 5 open design questions that were flagged for Director ratification: §8.1 — Module-level semantics: aggregate-across-module (preserves structural distinction between module-scope and per-function-scope). §8.2 — Multiple applications: fail-closed reject duplicate (lens, section) Enforce-mode pairs; multiple Introspect admitted (idempotent). §8.3 — Default-application budget: regression-detection class, gated on T-Lens-Behavioral-Parity COMPLETE; pre-cascade Introspect-only. §8.4 — Waiver lifecycle: future lens_stale_waivers lens with named dissolution trigger; tracked in lens-library-design.md §6. §8.5 — Cross-section composition: read declared budget, not computed class (preserves abstraction barrier; cost-of-change=1). Each resolution carries explicit reasoning grounded in INVARIANTS P2/P5 + feedback memory. Implementation can proceed once cascade gates clear (T-Lens-Behavioral-Parity COMPLETE for §8.3 flip; R2-Evaluator landed for worker dispatch precondition). No further Director ratification needed on these specific points. r3-structure.md row 16 updated to reflect the design-doc resolution. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): cross-design coherence pass + master design index Coherence audit across the 5 design docs identified 5 cross-doc conflicts; this commit resolves all 5 and lands the master index linking them. Fixes: 1. **Producer-query single-authority** (P2): complexity-lens §2 + cost-lens §3.2 now both reference `per_call_pattern_at(d, call_site) -> CallPattern?` as the typed query surface (single authority); the underlying `per_call_descent_evidence` side-table is named as the storage backend only. Eliminates parallel-authority risk. 2. **Cementing-test shape unified** (DB-15): cost-lens §5 reshaped from custom `ForAll { p: SourceProgram in programs }` (which violated tests- as-data §2.5 — quantifiers belong on claims, not predicates) to `QuantifiedTestClaim { generator, quantifier: ForAll, predicate: DifferentialEquals }`. Now matches complexity-lens §4 and tests-as-data §2.2 shape. 3. **DB-18 element-type-refinement cross-reference**: effect-enumeration §4.1 now explicitly states that DB-18's STOP-AND-ESCALATE locks the `WorkflowEffect` variant set + variant payload shape, not element-type within `LinearEffect.ops: List<X>`. The `OperationEffect` → `Operation` retypes is additive tightening within DB-18's permitted refinement scope. 4. **Resource-threaded signature compatibility**: cost-lens §3.3 now explicitly notes that `per_call_pattern_at` reads from threaded arrow signatures (per effect-enumeration §2.4) — signature-shape-agnostic producer; broadening covers both pre-migration and post-migration signature shapes. 5. **TestClaim shape for lens-application demonstrations**: lens-application §4 now declares all 4 worked-example closure gates use `TestClaim` (DB-15 enumerated form), not `QuantifiedTestClaim`. Property tests over the lens-application substrate live in T-Tests-As-Data scope, not T-Lens-Application-Surface scope. 6. **Register-migration sequencing**: tests-as-data §8.3 now lists the 4 sibling lens design docs whose register-row "→ COMPLETE" closure steps depend on the markdown→.dag migration landing first (substrate work in sibling lanes does NOT depend; only the closure-gate row update does). Plus: NEW `docs/design-r3-lens-substrate-index.md` — master index linking all 5 design docs, documenting cross-doc edges (substrate authority single-points + cementing-test format + cross-cutting invariants), and naming lane dispatch order. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): address 4 cursor findings on PR #1480 (sha 16340c5) 1. **Lane 16 row 40 stale text vs row 148 resolved** (P2 single-authority): row 40 still carried the original `CompileError | Warning | Silent` enum + `@complexity_budget_waived` annotation language; row 148 had the resolved `ViolationPolicy = Enforce | Introspect` + structural `ComplexityBudgetWaiver` carrier. Updated row 40 to match the resolved story (single authority). 2. **Line 44 duplicate (b) and (c) labels**: the Hybrid mechanism outer enumeration used (a)/(b)/(c) but referenced INVARIANTS §P5 sub- mechanisms (a)/(b)/(c) inside; same letter labels at different levels confused parsing. Renamed outer enumeration to (1)/(2)/(3) with footnote explaining the distinction. 3. **Line 175 contradicts line 173** (P5): line 175 said "Does enforce: tracked-debt rows get retirement PRs or explicit deferral" — the "or explicit deferral" reads like deferral remains an outcome, contradicting line 173's unconditional "no post-R3 deferral path". Removed the deferral language; line 175 now restates the unconditional rule + names the substrate-gap escalation path. 4. **design-complexity-lens-behavioral-completeness.md:125-127 variant- count mismatch** (P1 self-faithfulness): comment said "closed seven-variant set" / "Adding an eighth variant" but `AsymptoticClass` enumerates 8 variants (ClassConstant/Log/Linear/Linearithmic/ Quadratic/Polynomial/Exponential/Unknown). Updated comment to "eight-variant" / "ninth". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): retract cost-lens parallel SizeExpr proposal — align with complexity-lens single authority Cursor BLOCKING finding on PR #1480: cost-lens proposed a new SizeExpr 5-variant coproduct as authority, while complexity-lens proposed SizeVariable.display_name enrichment for the same SymbolicCost payloads. P2/P5 violation — same substrate fact, two incompatible target shapes. Resolution: complexity-lens has the structurally correct framing. - DB-7's SymbolicCost is the unified algebra (locked). - SymbolicCost already covers SizeAdd (via SumCost) and SizeMax (via dominance ordering) — no parallel SizeExpr algebra needed. - Descent semantics like "n - 1" live in std.computation::CallPattern (the canonical E-C site), not in size expressions. A SizeShrink variant would duplicate that fact in parallel. - Asymptotically O(n - 1) ≡ O(n); descent is a call-site property, not a size-shape property. Aligned cost-lens to complexity-lens: SizeVariable gains an optional display_name: String? field; no parallel SizeExpr carrier; SymbolicCost DB-7 lock preserved unchanged. Updated: - §1.1 problem framing — drop "size arithmetic" / "aggregate sizes" framing (already covered by SymbolicCost); keep only the "named-binding semantics" gap that motivates display_name. - §1.2 target shape — SizeVariable.display_name: String? (matches complexity-lens §1.2 verbatim). - §1.3 explicit rationale for unified-algebra over parallel-SizeExpr. - §1.4 migration shape — additive field, no carrier rename, no deletion. - §3 / §5 code examples — replaced SizePort with SizeVariable shape. - §8.1 resolved-question reframe — names the rejected alternative (parallel SizeExpr) for future readers. - §8.2 names-on-carrier resolution — display_name shape per §1.2. - §10 implementation step 1 closure gate renamed size_expr_substrate_landed → sizevariable_displayname_landed. P2 single-authority restored across the 5-doc design surface. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): effect-enumeration — read/write distinction via algebra inhabitance, not signature shape Cursor BLOCKING finding on PR #1480 at design-effect-enumeration-resource- threading.md:151: the design's "structural recognition" claim was actually convention-level. \`R in / R out\` and \`R in / R' out\` (same type, different value) have the SAME typed signature — \`.dag\` doesn't encode value- preservation as a substrate fact. ReadShaped vs WriteShaped via signature shape alone was P1 modeling-faithfulness violation. Resolution: split the unified rule into two structural carriers per §2.4: (a) Effect SET — derived from signature: resource types in input ∩ output. Structural; the signature carries it. (b) Effect KIND — declared via algebra inhabitance on the callable: \`inhabits IdempotentRead<R>\` (read), \`inhabits Mutating<R>\` (write), \`inhabits Append<R>\` (append). Structural; the inhabitance carrier captures it. The lens consults BOTH — signature for set, inhabitance for kind. Absence of any kind inhabitance with the resource in the effect set is a fail- closed Diagnostic (EffectKindUndeclared), not a silent default. Updates: - §2.1 line 151: replace "same-value vs modified" framing with explicit effect-set-vs-effect-kind distinction; cross-link to §2.4 + §8.1. - §2.3: same fix for Network read example. - §2.4: split the unified rule into (a) effect SET (signature) + (b) effect KIND (algebra inhabitance) with pseudocode for the lens-side classification. - §4.3: update EffectShape derivation source from "signature shape" to "algebra inhabitance lookup". - §8.1: full reframe — from "same-value resolved" to "algebra inhabitance is the structural authority", with explicit rationale (per-callable authority, not per-call; rejected phantom-marker alternative per feedback_no_annotations). - §3 lens fold pseudocode: dispatch on §2.4(a) for set + §2.4(b) for kind. Preserves the existing EffectShape = IsIdempotent | IsBreaking partition (per design-composed-effect-reshape.md PR #529 R3) — only the source of the shape changes (declared inhabitance, not derived from signature). P1 modeling-faithfulness restored. Cursor finding fully resolved. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): lens-application — collapse ApplicationConfig into sum-type, illegal states unrepresentable Cursor BLOCKING finding on PR #1480 at design-lens-application-surface.md:43: ApplicationConfig was a record with budget: LensBudget? + violation_policy: ViolationPolicy as separate fields. This admitted illegal state combinations: - Enforce + budget=None (illegal: enforcement requires a budget) - Introspect + budget=Some(_) (illegal: introspection takes no budget) The doc explicitly noted these as type-checker-enforced invariants (lines 136-137), but per feedback_state_space_vs_behavioral_invariants those are behavioral invariants, not state-space invariants — exactly the bug pattern modeling-discipline principles 2/6 prohibit. Illegal states must be unrepresentable at the type level. Resolution: collapse ApplicationConfig and ViolationPolicy into a single sum-type that pairs budget with Enforce by construction: ```dag type ApplicationConfig = Enforce { budget: LensBudget, diagnostic_severity: DiagnosticSeverity } | Introspect ``` By construction: - Enforce ALWAYS has a budget (it's a coordinate of the variant). - Introspect NEVER has a budget (it has no payload). The "Enforce without budget" and "Introspect with budget" combinations cannot be constructed; the type-checker has no rejection rule to enforce them — they don't exist in the state space. Updates: - §2: replaced ApplicationConfig record + ViolationPolicy sum with single ApplicationConfig sum carrying budget inside Enforce variant. - §3: rewrote framing to match — the binary Enforce/Introspect is the ApplicationConfig sum itself; budget pairing is structural. - §4: all 4 worked-example syntaxes updated to `Enforce { budget, diagnostic_severity }` directly (no separate violation_policy field). - §5.1: synthesized default-application uses `Enforce { budget: <inferred>, diagnostic_severity: Error }` shape. - §3.2: explicit-introspection override syntax `apply_lens(complexity, fn, Introspect)` (no separate budget=None). - r3-structure.md rows 40 + 148: updated substrate-carrier description to name ApplicationConfig as sum-type with the structural-invariance note. Modeling principles 2/6 honored. P1 modeling-faithfulness restored. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): codex non-blocking findings #2 + #3 — heading/count consistency Codex review on PR #1480 sha 58f49e9 noted two non-blocking inconsistencies: NB2: design-cost-lens-sizevar-dimension-wiring.md §4.2 heading said 'CommutativeSemiring<SymbolicCost>' but §8.5 resolves to 'Semiring<SymbolicCost>' (multiplicative side does NOT enforce commutativity per §8.5 reasoning). Fixed §4.2 heading to match §8.5 resolution. NB3: design-tests-as-data-completeness.md §3.1 said 'six classes' / 'decomposes into six structural classes' but §10 step 3 enumerates C1-C7 (seven classes). Fixed §3.1 to say 'seven classes' with explicit C1-C7 cross-reference. Both load-bearing for doc-as-authority discipline (P1 modeling-faithfulness of the spec to itself). (All 4 BLOCKING findings from same review at sha 58f49e9 are already addressed at earlier commits — see PR comment for the receipts: ef21e1a / 92d9b11 / 255cca3 / 8640e67.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): fix line 199 active-surface arithmetic + line 23 exploratory clarity Cursor APPROVE_WITH_COMMENTS finding on PR #1480 sha 92d9b11: **Main finding (line 199)**: arithmetic was internally inconsistent — "expanded from 13 active surfaces" + "4 new lanes + 1 new standing program" = 18, not 17. The baseline should have been 12 (12 lanes + 0 standing programs at the 2026-04-30 lock), making 12 + 5 = 17 consistent. Fixed by restating the baseline as 12 with explicit arithmetic: 4 new lanes (enumerated by name) + 1 new standing program = +5; 12 + 5 = 17. Also pinned T-Behavioral-Expectations-Documentation explicitly as "parallel-dispatchable across existing lanes, not a separate surface" so readers don't double-count it as a 5th new lane. **Exploratory finding (line 23)**: the "added..." list mixed 4 new lanes + T-Behavioral-Expectations-Documentation (not a separate lane) + standing program in one breath. Restructured the parenthetical to enumerate the 4 new lanes by name and call out T-Behavioral-Expectations-Documentation as parallel-dispatchable explicitly. Reader can no longer mis-count.

The §8.2 implementation note confirmed the parallel: "when display_name = Some(name), renderer uses it directly; when None, falls back to InternTable lookup". P2 single-authority violation; consumers could diverge on the same source_port. BLOCKING #4: master index design-r3-lens-substrate-index.md still claimed SizeExpr replaces SizeVariable, but cost-lens design (post-ef21e1a00) had already retracted SizeExpr in favor of unified SymbolicCost. Cross-doc authority drift. Resolution (both BLOCKINGs): - Drop display_name field entirely from cost-lens + complexity-lens designs. - SizeVariable substrate stays UNCHANGED at { source_port: PortId }. - InternTable is the single canonical name authority — already populated at parse time keyed by port_id. Renderer reads via intern_table::name_of(source_port). - The "Named SizeVar" gap from the capability register is closed by renderer-side wiring (no substrate change), not by adding a field. - Master index updated: SizeVariable line replaces the old SizeExpr line; notes InternTable as name authority. Updates: - design-cost-lens §1.2: target shape removes display_name field from SizeVariable carrier; rationale rewritten as InternTable-as-single-authority. - design-cost-lens §1.4 / §3 / §5 / §8.1 / §8.2: all display_name references scrubbed; "renderer-side InternTable name wiring" replaces "SizeVariable. display_name enrichment" throughout. - design-cost-lens §10 step 1: closure gate renamed sizevariable_displayname_landed -> renderer_intern_table_name_wiring_landed. - design-complexity-lens §1.2: same rewrite — SizeVariable carrier UNCHANGED; InternTable as name authority; explicit cross-link to cost-lens §1.2. - design-complexity-lens §7.2: resolved-question reframe. - design-r3-lens-substrate-index.md: SizeVariable line replaces SizeExpr line with InternTable-name-authority note. P2 single-authority restored. Cross-doc consistency restored.

Internal inconsistency. Fix: §Lane structure table row 138 updated to 13 types in scope, with explicit citation chain: - original 8-type count from PR #1430 §A audit - extended to 13 after fresh PM sweep found 5 additional Int-inherited refinement types (RetryCount / HttpStatus / Port / PositiveInt / NonNegativeInt) at dsl/std/types.dag:232-245 - Substrate Mgr ack at gunbc#1130 comment 4360482400 Includes: Nat-alignment opportunity flagged (NonNegativeInt → Nat, PositiveInt → Nat where range(min: 1)), cost-lens candidates for bounded-range types (RetryCount → Nat<3>, HttpStatus → Nat<10>, Port → Nat<16>) once refinement composition lands. Per Director recommendation: brief addendum documenting the audit so lane scope stays anchored. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): address PR #1480 cursor findings — §P5 mix-up + restored locked dispositions Fixes 3 cursor findings on PR #1480 (sha 0f32605d) plus 1 exploratory: 1. §P5(b)/(c) mix-up (line 44): "vague deferrals rejected" attributes to §P5(b) per-PR gate (the rule that actually rejects vague deferrals), not §P5(c) Velocity tripwire (windowed dispatch-pause). Now also explicitly surfaces §P5(c) as separate (b) windowed-enforcement clause. 2. Restored Post-R2 emergent work disposition on Substrate/PB continuation bullet (line 187): Director-locked 2026-04-28 — emergent post-R2 work absorbs into Substrate Manager continuation, not new managers. 3. Restored Verification scope negations on Verification Manager bullet (line 189): "L6 NOT in Verification scope" + "T-CostLens-Composition NOT in Verification scope" — both Director-locked 2026-04-28. 4. Updated stale "9 of 12" / "3 non-gated" counts in §"Dependency on R2" (lines 393, 397, 399, 400, 402) to "11 of 16" / "5 non-gated" matching line 59 Summary; added T-Lens-Behavioral-Parity + T-Lens-Application-Surface to Evaluator-gated list with cascade gate note. All Director-locked 2026-04-28 dispositions tagged "carried forward through 2026-05-02 expansion" so the locks survive the lane-count change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): close P5 escape hatch in r3_debt_paydown_zero_remaining gate Cursor BLOCKING finding on PR #1480 at docs/r3-structure.md:173: gate contradicted itself by allowing "deferred-to-post-R3 with Director sign-off" after stating "no tracked-debt rows survive R3 close", weakening P5/strict- forward-progress into a disposition convention. Fix: remove the deferral escape hatch entirely. Gate is unconditional — every tracked-debt row retires with PR receipt before R3 close. Grounds in user directive 2026-05-02: "all 'accidentally deferred to post R3' into R3 now". If a row appears unretirable, it surfaces as a substrate gap requiring a named R3 lane (the directive that motivated this manager's creation), not a Director-sign-off deferral. Cites INVARIANTS §P5 directly: tracked-debt deferred past R3 close is the bridge-as-steady-state pattern P5 explicitly forbids; the escape hatch reintroduced that pattern at lower cadence. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): reconcile T-Tests-As-Data-Completeness Evaluator-gating contradiction gpt-5-5-pro REQUEST_CHANGES finding on PR #1480 (sha 0f32605d): line 59 summary said T-Tests-As-Data-Completeness is in the "5 self-contained non-Evaluator-gated" group, but lane table at line 147 lists its dependency as "R2-Evaluator (test execution runtime)". Schedulers got two incompatible authorities (P2 single-authority violation). Lane table is correct — porting Rust tests to .dag TestClaim requires the Evaluator to execute the resulting test artifacts. Updated: - Line 59 summary: 11 → 12 Evaluator-gated; 5 → 4 non-gated; T-Tests-As- Data-Completeness moved into Evaluator-gated list with reason - Line 393 (Dependency on R2): same reclassification - Line 395 (substrate-carrier-fed list): drop T-Tests-As-Data-Completeness - Line 399 (precondition applies-to list): 11 → 12 lanes - Line 400 (carve-out): 5 → 4 lanes; drop T-Tests-As-Data-Completeness - Line 402 (split-resolution sentence): 11 → 12, 5 → 4 (Findings #2 and #3 already addressed at 0c449a869 and 0de2bda06 respectively.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): T-Lens-Application-Surface design doc — substrate shape + 4 worked examples Per user directive 2026-05-02 ("all designs upfront, implementation sketches if needed, minimize escalations"), authoring foundational design doc that unblocks T-Lens-Application-Surface lane dispatch. Resolves design questions: 1. **Section reference shape**: `SectionRef = DeclarationScope { DeclarationId } | NodeScope { DeclarationId, NodeId }`. Three of four user-named scopes (function / module / declaration) use DeclarationId uniformly; expression scope is the exception (NodeId required because expressions live inside Declaration body sub-DAGs). 2. **Violation-policy semantics**: user-named `CompileError | Warning | Silent` resolved to fail-closed-compatible binary `Enforce | Introspect` per INVARIANTS C-8. Warning forbidden (allows violations as steady state, bridge pattern P5 forbids); Silent forbidden ("silent None" exactly the pattern feedback_fail_closed_discipline bans). 3. **Default complexity-contract policy**: opt-out (compiler enforces; explicit waiver required). Waiver shape is structural `ComplexityBudgetWaiver` declaration with `justification` field, NOT an annotation per feedback_no_annotations. 4. **4 worked examples** ratified by Director (complexity-contract / CRDT cost / memory-peak cost / opt-in parallelism) — each grounded in substrate carriers + lens-fold integration. 5. **5 open design questions** flagged for Director ratification before substrate authoring begins (module-level semantics, multiple-applications- per-section, budget-inference for default, waiver dissolution, cross-section composition). Updates r3-structure.md lane 16 row to reference the design doc, replace the @complexity_budget_waived annotation language with structural carrier name, and replace the original `CompileError | Warning | Silent` enum with the fail-closed-resolved Enforce/Introspect binary. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): resolve all 5 §8 open design questions in-doc per minimize-escalations directive Per user directive 2026-05-02 ("minimize escalations"), resolved the 5 open design questions that were flagged for Director ratification: §8.1 — Module-level semantics: aggregate-across-module (preserves structural distinction between module-scope and per-function-scope). §8.2 — Multiple applications: fail-closed reject duplicate (lens, section) Enforce-mode pairs; multiple Introspect admitted (idempotent). §8.3 — Default-application budget: regression-detection class, gated on T-Lens-Behavioral-Parity COMPLETE; pre-cascade Introspect-only. §8.4 — Waiver lifecycle: future lens_stale_waivers lens with named dissolution trigger; tracked in lens-library-design.md §6. §8.5 — Cross-section composition: read declared budget, not computed class (preserves abstraction barrier; cost-of-change=1). Each resolution carries explicit reasoning grounded in INVARIANTS P2/P5 + feedback memory. Implementation can proceed once cascade gates clear (T-Lens-Behavioral-Parity COMPLETE for §8.3 flip; R2-Evaluator landed for worker dispatch precondition). No further Director ratification needed on these specific points. r3-structure.md row 16 updated to reflect the design-doc resolution. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): cross-design coherence pass + master design index Coherence audit across the 5 design docs identified 5 cross-doc conflicts; this commit resolves all 5 and lands the master index linking them. Fixes: 1. **Producer-query single-authority** (P2): complexity-lens §2 + cost-lens §3.2 now both reference `per_call_pattern_at(d, call_site) -> CallPattern?` as the typed query surface (single authority); the underlying `per_call_descent_evidence` side-table is named as the storage backend only. Eliminates parallel-authority risk. 2. **Cementing-test shape unified** (DB-15): cost-lens §5 reshaped from custom `ForAll { p: SourceProgram in programs }` (which violated tests- as-data §2.5 — quantifiers belong on claims, not predicates) to `QuantifiedTestClaim { generator, quantifier: ForAll, predicate: DifferentialEquals }`. Now matches complexity-lens §4 and tests-as-data §2.2 shape. 3. **DB-18 element-type-refinement cross-reference**: effect-enumeration §4.1 now explicitly states that DB-18's STOP-AND-ESCALATE locks the `WorkflowEffect` variant set + variant payload shape, not element-type within `LinearEffect.ops: List<X>`. The `OperationEffect` → `Operation` retypes is additive tightening within DB-18's permitted refinement scope. 4. **Resource-threaded signature compatibility**: cost-lens §3.3 now explicitly notes that `per_call_pattern_at` reads from threaded arrow signatures (per effect-enumeration §2.4) — signature-shape-agnostic producer; broadening covers both pre-migration and post-migration signature shapes. 5. **TestClaim shape for lens-application demonstrations**: lens-application §4 now declares all 4 worked-example closure gates use `TestClaim` (DB-15 enumerated form), not `QuantifiedTestClaim`. Property tests over the lens-application substrate live in T-Tests-As-Data scope, not T-Lens-Application-Surface scope. 6. **Register-migration sequencing**: tests-as-data §8.3 now lists the 4 sibling lens design docs whose register-row "→ COMPLETE" closure steps depend on the markdown→.dag migration landing first (substrate work in sibling lanes does NOT depend; only the closure-gate row update does). Plus: NEW `docs/design-r3-lens-substrate-index.md` — master index linking all 5 design docs, documenting cross-doc edges (substrate authority single-points + cementing-test format + cross-cutting invariants), and naming lane dispatch order. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): address 4 cursor findings on PR #1480 (sha 16340c52) 1. **Lane 16 row 40 stale text vs row 148 resolved** (P2 single-authority): row 40 still carried the original `CompileError | Warning | Silent` enum + `@complexity_budget_waived` annotation language; row 148 had the resolved `ViolationPolicy = Enforce | Introspect` + structural `ComplexityBudgetWaiver` carrier. Updated row 40 to match the resolved story (single authority). 2. **Line 44 duplicate (b) and (c) labels**: the Hybrid mechanism outer enumeration used (a)/(b)/(c) but referenced INVARIANTS §P5 sub- mechanisms (a)/(b)/(c) inside; same letter labels at different levels confused parsing. Renamed outer enumeration to (1)/(2)/(3) with footnote explaining the distinction. 3. **Line 175 contradicts line 173** (P5): line 175 said "Does enforce: tracked-debt rows get retirement PRs or explicit deferral" — the "or explicit deferral" reads like deferral remains an outcome, contradicting line 173's unconditional "no post-R3 deferral path". Removed the deferral language; line 175 now restates the unconditional rule + names the substrate-gap escalation path. 4. **design-complexity-lens-behavioral-completeness.md:125-127 variant- count mismatch** (P1 self-faithfulness): comment said "closed seven-variant set" / "Adding an eighth variant" but `AsymptoticClass` enumerates 8 variants (ClassConstant/Log/Linear/Linearithmic/ Quadratic/Polynomial/Exponential/Unknown). Updated comment to "eight-variant" / "ninth". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): retract cost-lens parallel SizeExpr proposal — align with complexity-lens single authority Cursor BLOCKING finding on PR #1480: cost-lens proposed a new SizeExpr 5-variant coproduct as authority, while complexity-lens proposed SizeVariable.display_name enrichment for the same SymbolicCost payloads. P2/P5 violation — same substrate fact, two incompatible target shapes. Resolution: complexity-lens has the structurally correct framing. - DB-7's SymbolicCost is the unified algebra (locked). - SymbolicCost already covers SizeAdd (via SumCost) and SizeMax (via dominance ordering) — no parallel SizeExpr algebra needed. - Descent semantics like "n - 1" live in std.computation::CallPattern (the canonical E-C site), not in size expressions. A SizeShrink variant would duplicate that fact in parallel. - Asymptotically O(n - 1) ≡ O(n); descent is a call-site property, not a size-shape property. Aligned cost-lens to complexity-lens: SizeVariable gains an optional display_name: String? field; no parallel SizeExpr carrier; SymbolicCost DB-7 lock preserved unchanged. Updated: - §1.1 problem framing — drop "size arithmetic" / "aggregate sizes" framing (already covered by SymbolicCost); keep only the "named-binding semantics" gap that motivates display_name. - §1.2 target shape — SizeVariable.display_name: String? (matches complexity-lens §1.2 verbatim). - §1.3 explicit rationale for unified-algebra over parallel-SizeExpr. - §1.4 migration shape — additive field, no carrier rename, no deletion. - §3 / §5 code examples — replaced SizePort with SizeVariable shape. - §8.1 resolved-question reframe — names the rejected alternative (parallel SizeExpr) for future readers. - §8.2 names-on-carrier resolution — display_name shape per §1.2. - §10 implementation step 1 closure gate renamed size_expr_substrate_landed → sizevariable_displayname_landed. P2 single-authority restored across the 5-doc design surface. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): effect-enumeration — read/write distinction via algebra inhabitance, not signature shape Cursor BLOCKING finding on PR #1480 at design-effect-enumeration-resource- threading.md:151: the design's "structural recognition" claim was actually convention-level. \`R in / R out\` and \`R in / R' out\` (same type, different value) have the SAME typed signature — \`.dag\` doesn't encode value- preservation as a substrate fact. ReadShaped vs WriteShaped via signature shape alone was P1 modeling-faithfulness violation. Resolution: split the unified rule into two structural carriers per §2.4: (a) Effect SET — derived from signature: resource types in input ∩ output. Structural; the signature carries it. (b) Effect KIND — declared via algebra inhabitance on the callable: \`inhabits IdempotentRead<R>\` (read), \`inhabits Mutating<R>\` (write), \`inhabits Append<R>\` (append). Structural; the inhabitance carrier captures it. The lens consults BOTH — signature for set, inhabitance for kind. Absence of any kind inhabitance with the resource in the effect set is a fail- closed Diagnostic (EffectKindUndeclared), not a silent default. Updates: - §2.1 line 151: replace "same-value vs modified" framing with explicit effect-set-vs-effect-kind distinction; cross-link to §2.4 + §8.1. - §2.3: same fix for Network read example. - §2.4: split the unified rule into (a) effect SET (signature) + (b) effect KIND (algebra inhabitance) with pseudocode for the lens-side classification. - §4.3: update EffectShape derivation source from "signature shape" to "algebra inhabitance lookup". - §8.1: full reframe — from "same-value resolved" to "algebra inhabitance is the structural authority", with explicit rationale (per-callable authority, not per-call; rejected phantom-marker alternative per feedback_no_annotations). - §3 lens fold pseudocode: dispatch on §2.4(a) for set + §2.4(b) for kind. Preserves the existing EffectShape = IsIdempotent | IsBreaking partition (per design-composed-effect-reshape.md PR #529 R3) — only the source of the shape changes (declared inhabitance, not derived from signature). P1 modeling-faithfulness restored. Cursor finding fully resolved. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): lens-application — collapse ApplicationConfig into sum-type, illegal states unrepresentable Cursor BLOCKING finding on PR #1480 at design-lens-application-surface.md:43: ApplicationConfig was a record with budget: LensBudget? + violation_policy: ViolationPolicy as separate fields. This admitted illegal state combinations: - Enforce + budget=None (illegal: enforcement requires a budget) - Introspect + budget=Some(_) (illegal: introspection takes no budget) The doc explicitly noted these as type-checker-enforced invariants (lines 136-137), but per feedback_state_space_vs_behavioral_invariants those are behavioral invariants, not state-space invariants — exactly the bug pattern modeling-discipline principles 2/6 prohibit. Illegal states must be unrepresentable at the type level. Resolution: collapse ApplicationConfig and ViolationPolicy into a single sum-type that pairs budget with Enforce by construction: ```dag type ApplicationConfig = Enforce { budget: LensBudget, diagnostic_severity: DiagnosticSeverity } | Introspect ``` By construction: - Enforce ALWAYS has a budget (it's a coordinate of the variant). - Introspect NEVER has a budget (it has no payload). The "Enforce without budget" and "Introspect with budget" combinations cannot be constructed; the type-checker has no rejection rule to enforce them — they don't exist in the state space. Updates: - §2: replaced ApplicationConfig record + ViolationPolicy sum with single ApplicationConfig sum carrying budget inside Enforce variant. - §3: rewrote framing to match — the binary Enforce/Introspect is the ApplicationConfig sum itself; budget pairing is structural. - §4: all 4 worked-example syntaxes updated to `Enforce { budget, diagnostic_severity }` directly (no separate violation_policy field). - §5.1: synthesized default-application uses `Enforce { budget: <inferred>, diagnostic_severity: Error }` shape. - §3.2: explicit-introspection override syntax `apply_lens(complexity, fn, Introspect)` (no separate budget=None). - r3-structure.md rows 40 + 148: updated substrate-carrier description to name ApplicationConfig as sum-type with the structural-invariance note. Modeling principles 2/6 honored. P1 modeling-faithfulness restored.

Fixed §4.2 heading to match §8.5 resolution. NB3: design-tests-as-data-completeness.md §3.1 said 'six classes' / 'decomposes into six structural classes' but §10 step 3 enumerates C1-C7 (seven classes).

The baseline should have been 12 (12 lanes + 0 standing programs at the 2026-04-30 lock), making 12 + 5 = 17 consistent. Fixed by restating the baseline as 12 with explicit arithmetic: 4 new lanes (enumerated by name) + 1 new standing program = +5; 12 + 5 = 17. Also pinned T-Behavioral-Expectations-Documentation explicitly as "parallel-dispatchable across existing lanes, not a separate surface" so readers don't double-count it as a 5th new lane. **Exploratory finding (line 23)**: the "added..." list mixed 4 new lanes + T-Behavioral-Expectations-Documentation (not a separate lane) + standing program in one breath. Restructured the parenthetical to enumerate the 4 new lanes by name and call out T-Behavioral-Expectations-Documentation as parallel-dispatchable explicitly. Reader can no longer mis-count.

The §8.2 implementation note confirmed the parallel: "when display_name = Some(name), renderer uses it directly; when None, falls back to InternTable lookup". P2 single-authority violation; consumers could diverge on the same source_port. BLOCKING #4: master index design-r3-lens-substrate-index.md still claimed SizeExpr replaces SizeVariable, but cost-lens design (post-ef21e1a00) had already retracted SizeExpr in favor of unified SymbolicCost. Cross-doc authority drift. Resolution (both BLOCKINGs): - Drop display_name field entirely from cost-lens + complexity-lens designs. - SizeVariable substrate stays UNCHANGED at { source_port: PortId }. - InternTable is the single canonical name authority — already populated at parse time keyed by port_id. Renderer reads via intern_table::name_of(source_port). - The "Named SizeVar" gap from the capability register is closed by renderer-side wiring (no substrate change), not by adding a field. - Master index updated: SizeVariable line replaces the old SizeExpr line; notes InternTable as name authority.

Fix: SectionedLensApplication<C> + ApplicationConfig<C> parametric in the lens carrier C; lens: Lens<C> and config.budget: C share the same C structurally. Mismatch is unrepresentable, not type-checker-rejected. Per-lens budgets dissolve into the existing Lens<C> carrier — no separate ComplexityBudget/CostBudget/ParallelismBudget carriers needed. BLOCKING #2: complexity-lens Certainty composed independently from cost dominance. Fix: define joint compose_summary function (§3.1) where certainty composition is cost-aware — when dominance drops a cost component, that component's certainty does NOT enter the result. Surfaces v2's implicit Θ(n²) Proven semantics; cost-unaware certainty would diverge from v2 on the cementing fixture corpus. BLOCKING #3: effect-enumeration line 17 prose still claimed signature is "one structural authority" for effects. Fix: updated to name the two orthogonal authorities — signature for effect SET, algebra inhabitance for effect KIND. Aligned with §2.4 + §8.1 that I'd already fixed at 92d9b11cf. BLOCKING #4: sibling lens docs and tests-as-data didn't share one cementing closure shape — complexity + effect proposed Rust cementing tests, cost (after my earlier fix at ef21e1a00) proposed QuantifiedTestClaim. Inconsistency. Fix: align all three on **Rust cementing today + dissolution trigger to tests-as-data step 5 .dag port**. Per-lens divergence is now explicitly forbidden in the master index. NB1: cost-lens §1.4 still said "single field addition" / "Rust mirror single field add" after the InternTable fix removed the field add. Cleaned up to "renderer-only, no substrate change". NB2: tests-as-data §3 said "17 variants" but enumerated 22 (Compiles ... BridgeLedgerZero). Fixed count to 22.

Three lines still referenced the old non-parametric framing: - Line 100: "type-checker verifies b inhabits lens.budget_type" — type-checker convention rather than structural typing. - Line 114: ApplicationConfig redeclared without <C> parameter. - Line 262: substrate-owner mention of "per-lens budget_type declaration extension". - Line 351: "each lens owns its own LensBudget definition" — implied separate budget carriers. - Line 357: implementation step said "Lens<C>.budget_type field added". All updated to reflect the parametric resolution (per §2): - ApplicationConfig<C> parametric in lens carrier C; lens/budget pair is structural via shared C. - Mismatch is unrepresentable, NOT type-checker-rejected. - No budget_type field on Lens<C>; the parameter C IS the structural authority. - Each lens's existing Lens<C> carrier IS the budget type; no new per-lens budget carriers. References to "budget_type" / "LensBudget" remain only in negation form ("not via budget_type field", "no LensBudget definition") to document the rejected alternative for future readers. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): lens-application — dissolve regression_baseline_pinned optional field Cursor BLOCKING at sha 98f2fc4f line 323 (actually line 308 — drift after prior edits): regression_baseline_pinned: AsymptoticClass? was an optional field on SectionedLensApplication where absence = introspection mode and presence = enforcement mode. This re-creates EXACTLY the illegal-states-representable pattern that the §2 ApplicationConfig sum-type fix dissolved (the original finding at design-lens-application- surface.md:43 from a prior wave). Fix: dissolve the optional field. The cascade-flip (T-Lens-Behavioral- Parity COMPLETE flipping default complexity from Introspect to Enforce) is purely SYNTHESIZER-side, not substrate-side: - Pre-cascade: synthesizer emits `Introspect` for every default complexity application. - Post-cascade: synthesizer emits `Enforce { budget: <computed class>, diagnostic_severity: Error }` — the computed class IS the regression baseline; the variant choice carries the fact structurally. No optional field on the carrier. The cascade just changes which variant the synthesizer constructs. Same illegal-states-unrepresentable discipline as §2. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): drop certainty_lattice — Certainty composition is cost-aware, not lattice-fold Cursor BLOCKING at sha 98f2fc4f line 196: join_certainty's "Proven wins under alternative" semantic was P1 unfaithful — a Proven branch arm could hide a Conservative arm carrying the actual worst-case bound, so the result's certainty would no longer faithfully describe the bound it qualifies. Same cost-unaware pattern as the §3.1 BLOCKING from earlier in the wave (composition independent from cost dominance). Resolution: drop the BoundedLattice<Certainty> declaration entirely. Certainty does NOT compose via lattice meet/join; composition is cost-aware per §3.1 compose_summary_* family. The lattice declaration was misleading — it suggested an independent composition pattern that contradicts the cost-aware design. Updates: - §1.5: removed `data certainty_lattice` declaration + meet_certainty + join_certainty function bodies. Replaced with prose explaining cost-aware composition + tightness-ordering distinction (ordering is implicit when projecting; not a composition operation). - §3.1: meet_certainty(...) call → meet_pair(...) inline helper, with explicit comment that it's used ONLY when both contributions survive cost composition (NOT a free-standing lattice op). - §11 cascade-gate list: removed "data certainty_lattice" from the class-5-grammar dependent declarations list with explanatory note. Same illegal-states-unrepresentable + cost-aware-composition discipline preserved end-to-end across the §3.1 + §1.5 + §3.x compose_summary_* chain.

This contradicts §2.4's locked rule that effect KIND is declared only via algebra inhabitance (inhabits IdempotentRead<R>), NOT derived from signature shape — same modeling-discipline violation as the line 151 BLOCKING from the prior wave (cursor BLOCKING #2 of this codex-wave). Resolution: rewrite §8.4 to derive readonly's deletion rationale from algebra inhabitance, not signature shape: - After migration, read kind is declared via `inhabits IdempotentRead<R>` on the callable (per §2.4 + §8.1) — structural fact. - The `readonly` keyword duplicates that inhabitance: same fact, two carriers. P2 single-authority + feedback_no_annotations forbid this. - Keyword is redundant AND drift-prone (feedback_state_space_vs_ behavioral_invariants: keyword could disagree with inhabitance). - Implementation-mechanical: every operation currently using `readonly` already has a corresponding `inhabits IdempotentRead<R>` declared at the migration site (one-to-one mapping in the atomic PR per §6). The §2.4 → §8.1 → §8.4 chain is now consistent end-to-end: signature carries effect SET; algebra inhabitance carries effect KIND; the readonly annotation is the same parallel-authority bug pattern P5/P2 forbid.

Tightened to commit to the stronger claim: cementing asserts structural equivalence on the FULL SymbolicCost/CostExpr carrier shape (not a projection). Asymptotic-class equivalence is a downstream consequence, not a substitute. Aligns with the structural_equivalent() function shape already declared at line 318. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): remove implicit Enforce-with-inferred-baseline; align Certainty no-lattice references Codex BLOCKING on PR #1488 sha 265d8ef7: §8.3 + §3.2 + §5.1 said the default complexity application post-cascade flips to Enforce mode with "budget = computed asymptotic class at synthesis time" — but the synthesizer recomputes from the current body each compile, so the baseline moves with the body. Whatever class the function has becomes both "current" and "baseline"; they always agree; no regression ever fires. The fact the design claimed to enforce was lost on every recompile. P2 single-authority + facts-flow-forward violation. Resolution: remove the implicit Enforce mode entirely. Default is Introspect-only for unannotated functions; user explicitly authors Enforce { budget: <chosen class>, ... } to opt into enforcement. No auto-inferred baseline — those would need persisted authority (either generated source, forbidden by feedback_no_generated_code_on_disk, or sidecar files, same problem). The structural answer: complexity contracts are user-authored. Re-framing "opt-out for complexity" per the original user directive: the user can opt out (by not authoring an Enforce application or by authoring Introspect); compile errors fire when the user opts IN with a budget the actual function exceeds. ComplexityBudgetWaiver retains its purpose — accepting known violations of explicit user contracts. Codex NB: residual references to "Certainty + lattice declaration" / "two new lattice instances" in complexity-lens lines 535 + 579 didn't match the §1.5 lattice deletion. Updated both to single BoundedLattice<AsymptoticClass> instance + Certainty 2-variant sum WITHOUT lattice (composition is cost-aware via §3.1 compose_summary_*). Updates: - §3.2 (Default policy): full reframe to user-driven contracts. - §5.1 (Default-application synthesis): synthesizer never emits Enforce; only Introspect for unannotated functions. - §8.3 (Default-application semantics): RESOLVED with new framing — user-driven contracts; no implicit baseline; explicit rationale for why generated-source is not the answer. - complexity-lens §5 step 2 + §7.4: drop "Certainty + lattice declaration" and "BoundedLattice<Certainty>" from the substrate-landing list and ROADMAP-P2 dissolution accounting. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): lens-application — add LensEnforcement<Output, Budget> projection carrier Codex BLOCKING on PR #1488 sha 265d8ef7 line 100: tying ApplicationConfig<C> to the same C as Lens<C> made the complexity lens budget = AsymptoticClass, but the complexity-lens design publishes Lookup<ComplexitySummary> with work/span/certainty as the lens output. Either drop downstream facts (force output = AsymptoticClass) or contradict the lens-output contract (output = ComplexitySummary; budget = AsymptoticClass; type system can't enforce compatibility). P1 modeling faithfulness + facts-flow-forward violation. Resolution: introduce LensEnforcement<Output, Budget> projection carrier in §2. Each lens declares both: - Lens<Output> for the read function (rich output type — load-bearing for lens-fold composition per compose_summary_*) - LensEnforcement<Output, Budget> for the projection from Output to the budget-comparable type (identity for cost; summary.asymptotic_class for complexity) SectionedLensApplication<Output, Budget> is parametric in BOTH parameters; the type system enforces lens/projection/budget compatibility through the shared Output and Budget. Mismatched triples (e.g., complexity-lens with SymbolicCost budget) are unrepresentable. Why projection rather than single-carrier: the lens output for complexity is rich (ComplexitySummary {work, span, asymptotic_class, certainty}) — required by §3.1 compose_summary_* composition. The budget is simple — the user's "function should be O(log n)" contract. Forcing budget = output over-constrains user authoring; forcing output = budget drops facts the composition needs. The projection separates the concerns. Updates: - §2: introduce LensEnforcement<Output, Budget>; SectionedLensApplication becomes parametric in (Output, Budget). Worked examples for all 4 lens enforcements added. - §3: ApplicationConfig<Budget> (was <C>); narrative updated to reference Output + Budget pair. - §6: Substrate Manager scope expanded to include LensEnforcement declarations. - §9 (NOT-modify list): per-lens budget types now declared via LensEnforcement, not via shared C. - §10 step 1: closure gate adds lens_enforcement_carrier_landed; substrate authoring includes per-lens LensEnforcement declarations. - design-r3-lens-substrate-index.md substrate-authority table: updated to list the 4 parametric carriers.

But §3 + line 129 said Introspect has "no projection or comparison" — leaving Introspect carrying enforcement metadata it cannot consume. P2 / illegal-states-unrepresentable: an Introspect application should not have enforcement axes. Resolution: split into two carriers + sum: - EnforcedApplication<Output, Budget> — carries lens, enforcement, section, budget, diagnostic_severity, span. Both type parameters relevant. - IntrospectApplication<Output> — carries only lens, section, span. No Budget axis, no enforcement projection. - SectionedLensApplication = Enforce<O,B>(EnforcedApplication<O,B>) | Introspect<O>(IntrospectApplication<O>) — sum where each variant carries exactly its required parameters. Now Introspect cannot accidentally carry enforcement state; mismatched triples (lens, projection, budget) remain unrepresentable for Enforce applications. Both illegal classes structurally rejected. BLOCKING #2 (cost-lens line 332): residual paragraph still said "The QuantifiedTestClaim runs..." asserting equivalence on asymptotic class only — contradicted line 312's "Rust cementing test today" + line 316's "full SymbolicCost/CostExpr structural equivalence" Band-C parity claim. Two incompatible closure-gate authorities in same section. Resolution: rewrote line 332 to align with Rust cementing + full SymbolicCost/CostExpr structural equivalence. Single authority restored. Also updated downstream references: - §3 narrative: ApplicationConfig sum-type declaration removed (folded into EnforcedApplication directly per §2). Pairing semantics still documented; the carrier shape is the single authority. - §3.2 ComplexityBudgetWaiver rationale: updated to "an Introspect application" instead of "SectionedLensApplication { config: Introspect }". - §4.1 worked example: substrate-after-parsing block now uses Enforce<ComplexitySummary, AsymptoticClass>(EnforcedApplication { ... }) with all coordinates explicit. - §5.1 default synthesis: synthesizer emits Introspect<ComplexitySummary>(IntrospectApplication { ... }). - §6 substrate-owner scope: 5 carriers now (was 4 before split). - §10 step 1: closure gates updated; substrate authoring includes per-variant carriers + per-lens LensEnforcement declarations. - master index substrate-authority table: row updated to reflect the carrier split. - r3-structure.md rows 40 + 148: lane-row carriers list updated to match the per-variant shape.

Parallel prose authority for the same decision violated P2 (single authoritative description) — r3-structure summary contradicted the canonical owning design doc. Fixed both occurrences to match the resolved framing: - Unannotated functions: synthesized Introspect-only. - Enforcement: requires explicit user authoring of apply_lens with Enforce + budget. - "Opt-out" reframed: user can opt out (no Enforce / explicit Introspect); compile errors fire when user opts IN with a budget the function exceeds. - ComplexityBudgetWaiver preserved purpose: accepting known violations of explicit user contracts.

The check would have been API-level convention (the fold-pass hardcoding "use lattice ordering for AsymptoticClass / dominance for SymbolicCost / mode-mismatch for ParallelismMode" instead of reading declared facts). P2/P6 single-authority + API-level-enforcement violation. Resolution: extend LensEnforcement<Output, Budget> to carry both the projection AND the violation relation: ```dag type LensEnforcement<Output, Budget> { project: Output -> Budget violates: (declared: Budget, observed: Budget) -> Bool } ``` Each per-lens enforcement declares its own violation semantics structurally: - complexity_enforcement.violates: lattice ordering on AsymptoticClass - cost_enforcement.violates: dominance ordering on SymbolicCost (observed dominates declared) - parallelism_enforcement.violates: mode-mismatch (OptInIndependent declared but lens computed Sequential = violation) The fold-pass dispatch reads the per-lens violation relation directly (no hardcoded comparison logic in the fold-pass; the dispatch is fully substrate-driven). Updates: - §2 LensEnforcement carrier definition: extended with violates field + rationale. - §2 per-lens enforcement examples: each declares both project and violates. - §4.1 worked example "Compiler-side processing": fold-pass description reads enforcement.project then enforcement.violates. - §5 lens-fold integration step 2: dispatch reads project + violates.

Span has independent dominance from work (different inputs to iterate — span uses outer.work + body.span, while work uses outer.work + body.work). A conservative span contributor could be dropped from work's dominance walk while its span bound survived in span's dominance walk — the surviving span contributor's certainty would not enter the result's certainty. P1 modeling faithfulness + facts-flow- forward: certainty no longer faithful to the bound it qualifies on the span dimension. Resolution: per-dimension cost-aware certainty composition. Each dimension (work, span, future per-DB-3) computes its own surviving- contributor certainty independently; the result certainty is the meet across dimensions (any unproven dimension makes the whole result unproven). ```dag let work_cert = certainty_of_surviving_per_dim(outer, body, outer.work, body.work, composed_work) let span_cert = certainty_of_surviving_per_dim(outer, body, outer.work, body.span, composed_span) let composed_certainty = meet_pair(work_cert, span_cert) ``` certainty_of_surviving_per_dim is generalized to take per-dimension inputs (outer's contribution to this dimension, body's contribution, the composed dimension result) and walks dominance specifically on that dimension. Updates: - §3.1 compose_summary_iterate: per-dimension certainty composition with explicit work + span tracking. - §3.1 certainty_of_surviving renamed to certainty_of_surviving_per_dim; signature parameterized over dimension. - §3.1 compose_summary_sequential / compose_summary_branch comments updated to name the per-dimension pattern. - §1.5 (Why no BoundedLattice<Certainty>): updated to reference certainty_of_surviving_per_dim and per-dimension composition.

But callable_arrow_effect TODAY derives effect kind from signature/body shape — if the body stays unchanged, it does NOT consume the new inhabits IdempotentRead<R> / inhabits Mutating<R> facts. Facts-flow-forward / P2 violation: new substrate authority not consumed by downstream. Resolution: the lens body MUST change in its kind-classification dispatch. Specifically: - The fold STRUCTURE (per-callable walk + report aggregation) is unchanged. - The per-callable kind classifier IS rewritten — from signature/body shape inference to algebra-inhabitance lookup (callable_inhabits(callable, idempotent_read_for(resource)) / callable_inhabits(callable, mutating_for(resource))). Updates: - §6.2 first reason: lens body framing flipped from "does not change" to "changes only in its kind-classification dispatch", with explicit rationale citing this BLOCKING. - §9 NOT-modify list: lens fold STRUCTURE preserved; per-callable kind classifier explicitly listed as modified (with cross-reference). - §9 size estimate: "lens-fold itself is unchanged" → "lens-fold structure is unchanged; per-callable kind classifier rewrite is S". - §10 implementation order: NEW step 5 ("Lens kind-classifier rewrite") inserted between OperationEffect retirement (step 4) and cementing test (now step 6).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): §8.5 implementation note — read EnforcedApplication.budget, not config.budget Codex BLOCKING on PR #1488 sha a525baf0: §8.5 still pointed implementers at `config.budget`, but the per-variant split at 968994843 dissolved ApplicationConfig — budget now lives on EnforcedApplication<Output, Budget> inside the Enforce variant of SectionedLensApplication. Stale implementation guidance pointing at non-existent authority. P2 violation. Fixed: §8.5 now describes the lens-fold matching on Enforce(EnforcedApplication { budget, ... }) and the Introspect case (no budget). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): effect-enumeration lens body reads signature directly, not via LensEnforcement Cursor BLOCKING on PR #1488 sha c41b8ce8 line 373: my §6.2 fix said the new effect_enumeration lens body "reads enforcement.project for the effect set". But LensEnforcement is the lens-application-surface budget-projection carrier (T-Lens-Application-Surface lane). The effect-enumeration lens body is part of T-Lens-Behavioral-Parity slice 4 — which CASCADES into T-Lens-Application-Surface (the latter gates on the former being COMPLETE). Reading enforcement.project from the lens body inverts the cascade AND gives the effect-set fact a second authority (signature-derived per §2.4(a) vs LensEnforcement projection). Resolution: lens body reads effect set DIRECTLY from the callable's arrow signature (existing substrate query — resource types in input ∩ output, per §2.4(a)). Kind classification reads callable_inhabits(...) per §2.4(b). Both queries are within T-Lens-Behavioral-Parity slice 4 scope; neither depends on LensEnforcement. Updated §6.2 line 373 to: - Replace "reads enforcement.project for the effect set" with "reads the effect set directly from the callable's arrow signature (existing substrate query; structurally derivable per §2.4(a) without any lens-application-surface artifact)". - Add explicit "neither depends on LensEnforcement from T-Lens- Application-Surface (cascade flows the other direction)". Cascade direction preserved: T-Lens-Behavioral-Parity COMPLETE → T-Lens-Application-Surface, not vice versa. Effect-set fact has single authority (signature query); kind fact has single authority (algebra inhabitance). No lens-application carriers consumed by lens body. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): per-coordinate certainty on ComplexitySummary (no global collapse) Codex BLOCKING on PR #1488 sha 75a6ab57: §3.1 computed independent work_cert and span_cert per-dimension, then immediately collapsed them into one global ComplexitySummary.certainty via meet_pair. That collapse loses the per-dimension proof-tightness fact: if work is Proven but span is Conservative (or vice versa), downstream display/enforcement consumers see only "globally Conservative" and cannot know the work bound was proven. P1 modeling faithfulness + P2 facts-flow-forward violation: the certainty fact each dimension carries gets fused into ambiguity. Resolution: ComplexitySummary now carries per-coordinate certainty — work_certainty and span_certainty as independent fields. No global certainty field; no meet across dimensions. Each coordinate's certainty stays on that coordinate through composition. ```dag type ComplexitySummary { work: SymbolicCost span: SymbolicCost asymptotic_class: AsymptoticClass work_certainty: Certainty // per-coordinate per BLOCKING fix span_certainty: Certainty } ``` Updates: - §1.7 ComplexitySummary declaration: split certainty into work_certainty + span_certainty with explicit rationale citing this BLOCKING. - §3 ComplexitySummary declaration in lens body section: same split. - §3 outer Loop construction: outer.span = outer.work, so both certainties = bound_cert. - §3.1 compose_summary_iterate: drop the global meet across dimensions; work_certainty := work_cert, span_certainty := span_cert independently. - §3.1 certainty_of_surviving_per_dim signature: takes per-dimension certainty inputs (outer_cert, body_cert) explicitly; no global outer.certainty / body.certainty lookup. - §3.1 compose_summary_sequential / compose_summary_branch comments: pattern updated to "no meet across dimensions; per-coordinate independence preserved on output". asymptotic_class is still a projection of work; its certainty is work_certainty (no separate class_certainty since the class is derived, not independent). All facts faithful to the dimension they qualify. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): align lens-application doc with per-coordinate certainty (work_certainty / span_certainty) Cursor APPROVE_WITH_COMMENTS finding on PR #1488 sha 37f3bc62: lens- application-surface lines 125 + 152 still described ComplexitySummary with a single `certainty` field, but my fix at 955cafe2c split certainty into per-coordinate work_certainty + span_certainty in the complexity- lens design. Sibling-doc mismatch — same carrier shape described two ways across two design docs in the same PR. Updated lines 125 + 152 to match complexity-lens §1.7's per-coordinate shape: - Line 125 inline comment: "rich output: work/span/asymptotic_class/ work_certainty/span_certainty". - Line 152 narrative: "rich (ComplexitySummary { work, span, asymptotic_class, work_certainty, span_certainty } — per complexity- lens §1.7, certainty is per-coordinate to avoid collapsing per- dimension proof-tightness facts)". - "Forcing output = budget would drop work/span/certainty facts" → "drop work/span/per-coordinate-certainty facts". Cross-doc carrier-shape consistency restored.

Verified: src/v3/std/algebra.dag:143 explicitly says "InternTable lookup the lens doesn't yet run". v3 has some InternTable machinery (PR #367 Phase 1) but the port-id-to-name query is NOT landed. Cannot assume it. Resolution: re-introduce SizeVariable.display_name: String? as the single substrate authority for the user-facing name. No InternTable lookup assumed. Field is single-source (not parallel with anything); parser populates from authored binding names where present, None for inferred. Earlier "parallel authority" concern (gpt-5-5-pro at ef21e1a0) doesn't apply because there's no second source — InternTable lookup isn't landed and isn't claimed. BLOCKING #2 (per-variant generics): doc declared SectionedLensApplication = Enforce<Output, Budget>(...) | Introspect< Output>(...) — but v3 .dag sums use uniform type parameters across variants (e.g., Lookup<C> = Miss | Hit(C); both share C). Per-variant parameter binding / existential packaging not currently supported. Resolution: drop the SectionedLensApplication SUM. Use TWO SEPARATE top-level carriers — EnforcedApplication<Output, Budget> and IntrospectApplication<Output>. Lens-fold pass walks two separate lists and emits Diagnostics from Enforce walks, records values from Introspect walks. No per-variant generics required. Each lens application in .dag source is one or the other; user authoring chooses at apply_lens site. BLOCKING #3 (TestPredicate maturity): doc said "Today's TestPredicate coproduct covers 22 variants" listed by name, treating them as uniformly-live substrate. Per verification.dag inline annotations, many are 🟡 Scaffold with named dissolution triggers (ExecuteCommand, ForAllTargets, LensOutputEquals, DifferentialEquals, BinaryDimensionReportEquals, AlgebraicLaw, ReleaseDeferredClaim, SubstrateResearchDeferredClaim). Resolution: §1 explicitly disclose 🟢 TERMINAL vs 🟡 Scaffold partition; note that ports landing on Scaffold variants are inherently scoped by that variant's named dissolution trigger; new-carrier residual is in scope of T-Tests-As-Data-Completeness, not assumed live. Updates: - design-cost-lens §1.2: SizeVariable.display_name reintroduced as single authority; revert §1.4 from renderer-only to additive field; both wave reviews now reconciled. - design-lens-application-surface §2: SectionedLensApplication sum removed; two top-level carriers (EnforcedApplication + IntrospectApplication). Downstream §3 + §4 + §5 + §6 + §8.5 + §9 + §10 references updated to "two separate top-level carriers" framing. - design-tests-as-data §1: TestPredicate maturity disclosure (TERMINAL vs Scaffold partition with named dissolution triggers per verification.dag inline annotations). - design-r3-lens-substrate-index: substrate-authority table updated to drop "sum" and list two separate carriers. All three BLOCKINGs reflect the constraint: design docs cannot assume substrate facilities not yet landed, and cannot use shapes v3 cannot currently express.

Now also explicitly surfaces §P5(c) as separate (b) windowed-enforcement clause. 2. Restored Post-R2 emergent work disposition on Substrate/PB continuation bullet (line 187): Director-locked 2026-04-28 — emergent post-R2 work absorbs into Substrate Manager continuation, not new managers. 3. Restored Verification scope negations on Verification Manager bullet (line 189): "L6 NOT in Verification scope" + "T-CostLens-Composition NOT in Verification scope" — both Director-locked 2026-04-28. 4. Updated stale "9 of 12" / "3 non-gated" counts in §"Dependency on R2" (lines 393, 397, 399, 400, 402) to "11 of 16" / "5 non-gated" matching line 59 Summary; added T-Lens-Behavioral-Parity + T-Lens-Application-Surface to Evaluator-gated list with cascade gate note. All Director-locked 2026-04-28 dispositions tagged "carried forward through 2026-05-02 expansion" so the locks survive the lane-count change.

Fix: remove the deferral escape hatch entirely. Gate is unconditional — every tracked-debt row retires with PR receipt before R3 close. Grounds in user directive 2026-05-02: "all 'accidentally deferred to post R3' into R3 now". If a row appears unretirable, it surfaces as a substrate gap requiring a named R3 lane (the directive that motivated this manager's creation), not a Director-sign-off deferral. Cites INVARIANTS §P5 directly: tracked-debt deferred past R3 close is the bridge-as-steady-state pattern P5 explicitly forbids; the escape hatch reintroduced that pattern at lower cadence.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): T-Lens-Application-Surface design doc — substrate shape + 4 worked examples Per user directive 2026-05-02 ("all designs upfront, implementation sketches if needed, minimize escalations"), authoring foundational design doc that unblocks T-Lens-Application-Surface lane dispatch. Resolves design questions: 1. **Section reference shape**: `SectionRef = DeclarationScope { DeclarationId } | NodeScope { DeclarationId, NodeId }`. Three of four user-named scopes (function / module / declaration) use DeclarationId uniformly; expression scope is the exception (NodeId required because expressions live inside Declaration body sub-DAGs). 2. **Violation-policy semantics**: user-named `CompileError | Warning | Silent` resolved to fail-closed-compatible binary `Enforce | Introspect` per INVARIANTS C-8. Warning forbidden (allows violations as steady state, bridge pattern P5 forbids); Silent forbidden ("silent None" exactly the pattern feedback_fail_closed_discipline bans). 3. **Default complexity-contract policy**: opt-out (compiler enforces; explicit waiver required). Waiver shape is structural `ComplexityBudgetWaiver` declaration with `justification` field, NOT an annotation per feedback_no_annotations. 4. **4 worked examples** ratified by Director (complexity-contract / CRDT cost / memory-peak cost / opt-in parallelism) — each grounded in substrate carriers + lens-fold integration. 5. **5 open design questions** flagged for Director ratification before substrate authoring begins (module-level semantics, multiple-applications- per-section, budget-inference for default, waiver dissolution, cross-section composition). Updates r3-structure.md lane 16 row to reference the design doc, replace the @complexity_budget_waived annotation language with structural carrier name, and replace the original `CompileError | Warning | Silent` enum with the fail-closed-resolved Enforce/Introspect binary. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): resolve all 5 §8 open design questions in-doc per minimize-escalations directive Per user directive 2026-05-02 ("minimize escalations"), resolved the 5 open design questions that were flagged for Director ratification: §8.1 — Module-level semantics: aggregate-across-module (preserves structural distinction between module-scope and per-function-scope). §8.2 — Multiple applications: fail-closed reject duplicate (lens, section) Enforce-mode pairs; multiple Introspect admitted (idempotent). §8.3 — Default-application budget: regression-detection class, gated on T-Lens-Behavioral-Parity COMPLETE; pre-cascade Introspect-only. §8.4 — Waiver lifecycle: future lens_stale_waivers lens with named dissolution trigger; tracked in lens-library-design.md §6. §8.5 — Cross-section composition: read declared budget, not computed class (preserves abstraction barrier; cost-of-change=1). Each resolution carries explicit reasoning grounded in INVARIANTS P2/P5 + feedback memory. Implementation can proceed once cascade gates clear (T-Lens-Behavioral-Parity COMPLETE for §8.3 flip; R2-Evaluator landed for worker dispatch precondition). No further Director ratification needed on these specific points. r3-structure.md row 16 updated to reflect the design-doc resolution. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): cross-design coherence pass + master design index Coherence audit across the 5 design docs identified 5 cross-doc conflicts; this commit resolves all 5 and lands the master index linking them. Fixes: 1. **Producer-query single-authority** (P2): complexity-lens §2 + cost-lens §3.2 now both reference `per_call_pattern_at(d, call_site) -> CallPattern?` as the typed query surface (single authority); the underlying `per_call_descent_evidence` side-table is named as the storage backend only. Eliminates parallel-authority risk. 2. **Cementing-test shape unified** (DB-15): cost-lens §5 reshaped from custom `ForAll { p: SourceProgram in programs }` (which violated tests- as-data §2.5 — quantifiers belong on claims, not predicates) to `QuantifiedTestClaim { generator, quantifier: ForAll, predicate: DifferentialEquals }`. Now matches complexity-lens §4 and tests-as-data §2.2 shape. 3. **DB-18 element-type-refinement cross-reference**: effect-enumeration §4.1 now explicitly states that DB-18's STOP-AND-ESCALATE locks the `WorkflowEffect` variant set + variant payload shape, not element-type within `LinearEffect.ops: List<X>`. The `OperationEffect` → `Operation` retypes is additive tightening within DB-18's permitted refinement scope. 4. **Resource-threaded signature compatibility**: cost-lens §3.3 now explicitly notes that `per_call_pattern_at` reads from threaded arrow signatures (per effect-enumeration §2.4) — signature-shape-agnostic producer; broadening covers both pre-migration and post-migration signature shapes. 5. **TestClaim shape for lens-application demonstrations**: lens-application §4 now declares all 4 worked-example closure gates use `TestClaim` (DB-15 enumerated form), not `QuantifiedTestClaim`. Property tests over the lens-application substrate live in T-Tests-As-Data scope, not T-Lens-Application-Surface scope. 6. **Register-migration sequencing**: tests-as-data §8.3 now lists the 4 sibling lens design docs whose register-row "→ COMPLETE" closure steps depend on the markdown→.dag migration landing first (substrate work in sibling lanes does NOT depend; only the closure-gate row update does). Plus: NEW `docs/design-r3-lens-substrate-index.md` — master index linking all 5 design docs, documenting cross-doc edges (substrate authority single-points + cementing-test format + cross-cutting invariants), and naming lane dispatch order. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): address 4 cursor findings on PR #1480 (sha 16340c52) 1. **Lane 16 row 40 stale text vs row 148 resolved** (P2 single-authority): row 40 still carried the original `CompileError | Warning | Silent` enum + `@complexity_budget_waived` annotation language; row 148 had the resolved `ViolationPolicy = Enforce | Introspect` + structural `ComplexityBudgetWaiver` carrier. Updated row 40 to match the resolved story (single authority). 2. **Line 44 duplicate (b) and (c) labels**: the Hybrid mechanism outer enumeration used (a)/(b)/(c) but referenced INVARIANTS §P5 sub- mechanisms (a)/(b)/(c) inside; same letter labels at different levels confused parsing. Renamed outer enumeration to (1)/(2)/(3) with footnote explaining the distinction. 3. **Line 175 contradicts line 173** (P5): line 175 said "Does enforce: tracked-debt rows get retirement PRs or explicit deferral" — the "or explicit deferral" reads like deferral remains an outcome, contradicting line 173's unconditional "no post-R3 deferral path". Removed the deferral language; line 175 now restates the unconditional rule + names the substrate-gap escalation path. 4. **design-complexity-lens-behavioral-completeness.md:125-127 variant- count mismatch** (P1 self-faithfulness): comment said "closed seven-variant set" / "Adding an eighth variant" but `AsymptoticClass` enumerates 8 variants (ClassConstant/Log/Linear/Linearithmic/ Quadratic/Polynomial/Exponential/Unknown). Updated comment to "eight-variant" / "ninth". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): retract cost-lens parallel SizeExpr proposal — align with complexity-lens single authority Cursor BLOCKING finding on PR #1480: cost-lens proposed a new SizeExpr 5-variant coproduct as authority, while complexity-lens proposed SizeVariable.display_name enrichment for the same SymbolicCost payloads. P2/P5 violation — same substrate fact, two incompatible target shapes. Resolution: complexity-lens has the structurally correct framing. - DB-7's SymbolicCost is the unified algebra (locked). - SymbolicCost already covers SizeAdd (via SumCost) and SizeMax (via dominance ordering) — no parallel SizeExpr algebra needed. - Descent semantics like "n - 1" live in std.computation::CallPattern (the canonical E-C site), not in size expressions. A SizeShrink variant would duplicate that fact in parallel. - Asymptotically O(n - 1) ≡ O(n); descent is a call-site property, not a size-shape property. Aligned cost-lens to complexity-lens: SizeVariable gains an optional display_name: String? field; no parallel SizeExpr carrier; SymbolicCost DB-7 lock preserved unchanged. Updated: - §1.1 problem framing — drop "size arithmetic" / "aggregate sizes" framing (already covered by SymbolicCost); keep only the "named-binding semantics" gap that motivates display_name. - §1.2 target shape — SizeVariable.display_name: String? (matches complexity-lens §1.2 verbatim). - §1.3 explicit rationale for unified-algebra over parallel-SizeExpr. - §1.4 migration shape — additive field, no carrier rename, no deletion. - §3 / §5 code examples — replaced SizePort with SizeVariable shape. - §8.1 resolved-question reframe — names the rejected alternative (parallel SizeExpr) for future readers. - §8.2 names-on-carrier resolution — display_name shape per §1.2. - §10 implementation step 1 closure gate renamed size_expr_substrate_landed → sizevariable_displayname_landed. P2 single-authority restored across the 5-doc design surface. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): effect-enumeration — read/write distinction via algebra inhabitance, not signature shape Cursor BLOCKING finding on PR #1480 at design-effect-enumeration-resource- threading.md:151: the design's "structural recognition" claim was actually convention-level. \`R in / R out\` and \`R in / R' out\` (same type, different value) have the SAME typed signature — \`.dag\` doesn't encode value- preservation as a substrate fact. ReadShaped vs WriteShaped via signature shape alone was P1 modeling-faithfulness violation. Resolution: split the unified rule into two structural carriers per §2.4: (a) Effect SET — derived from signature: resource types in input ∩ output. Structural; the signature carries it. (b) Effect KIND — declared via algebra inhabitance on the callable: \`inhabits IdempotentRead<R>\` (read), \`inhabits Mutating<R>\` (write), \`inhabits Append<R>\` (append). Structural; the inhabitance carrier captures it. The lens consults BOTH — signature for set, inhabitance for kind. Absence of any kind inhabitance with the resource in the effect set is a fail- closed Diagnostic (EffectKindUndeclared), not a silent default. Updates: - §2.1 line 151: replace "same-value vs modified" framing with explicit effect-set-vs-effect-kind distinction; cross-link to §2.4 + §8.1. - §2.3: same fix for Network read example. - §2.4: split the unified rule into (a) effect SET (signature) + (b) effect KIND (algebra inhabitance) with pseudocode for the lens-side classification. - §4.3: update EffectShape derivation source from "signature shape" to "algebra inhabitance lookup". - §8.1: full reframe — from "same-value resolved" to "algebra inhabitance is the structural authority", with explicit rationale (per-callable authority, not per-call; rejected phantom-marker alternative per feedback_no_annotations). - §3 lens fold pseudocode: dispatch on §2.4(a) for set + §2.4(b) for kind. Preserves the existing EffectShape = IsIdempotent | IsBreaking partition (per design-composed-effect-reshape.md PR #529 R3) — only the source of the shape changes (declared inhabitance, not derived from signature).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): lens-application — collapse ApplicationConfig into sum-type, illegal states unrepresentable Cursor BLOCKING finding on PR #1480 at design-lens-application-surface.md:43: ApplicationConfig was a record with budget: LensBudget? + violation_policy: ViolationPolicy as separate fields. This admitted illegal state combinations: - Enforce + budget=None (illegal: enforcement requires a budget) - Introspect + budget=Some(_) (illegal: introspection takes no budget) The doc explicitly noted these as type-checker-enforced invariants (lines 136-137), but per feedback_state_space_vs_behavioral_invariants those are behavioral invariants, not state-space invariants — exactly the bug pattern modeling-discipline principles 2/6 prohibit. Illegal states must be unrepresentable at the type level. Resolution: collapse ApplicationConfig and ViolationPolicy into a single sum-type that pairs budget with Enforce by construction: ```dag type ApplicationConfig = Enforce { budget: LensBudget, diagnostic_severity: DiagnosticSeverity } | Introspect ``` By construction: - Enforce ALWAYS has a budget (it's a coordinate of the variant). - Introspect NEVER has a budget (it has no payload). The "Enforce without budget" and "Introspect with budget" combinations cannot be constructed; the type-checker has no rejection rule to enforce them — they don't exist in the state space. Updates: - §2: replaced ApplicationConfig record + ViolationPolicy sum with single ApplicationConfig sum carrying budget inside Enforce variant. - §3: rewrote framing to match — the binary Enforce/Introspect is the ApplicationConfig sum itself; budget pairing is structural. - §4: all 4 worked-example syntaxes updated to `Enforce { budget, diagnostic_severity }` directly (no separate violation_policy field). - §5.1: synthesized default-application uses `Enforce { budget: <inferred>, diagnostic_severity: Error }` shape. - §3.2: explicit-introspection override syntax `apply_lens(complexity, fn, Introspect)` (no separate budget=None). - r3-structure.md rows 40 + 148: updated substrate-carrier description to name ApplicationConfig as sum-type with the structural-invariance note. Modeling principles 2/6 honored. P1 modeling-faithfulness restored.

The baseline should have been 12 (12 lanes + 0 standing programs at the 2026-04-30 lock), making 12 + 5 = 17 consistent. Fixed by restating the baseline as 12 with explicit arithmetic: 4 new lanes (enumerated by name) + 1 new standing program = +5; 12 + 5 = 17. Also pinned T-Behavioral-Expectations-Documentation explicitly as "parallel-dispatchable across existing lanes, not a separate surface" so readers don't double-count it as a 5th new lane. **Exploratory finding (line 23)**: the "added..." list mixed 4 new lanes + T-Behavioral-Expectations-Documentation (not a separate lane) + standing program in one breath.

The §8.2 implementation note confirmed the parallel: "when display_name = Some(name), renderer uses it directly; when None, falls back to InternTable lookup". P2 single-authority violation; consumers could diverge on the same source_port. BLOCKING #4: master index design-r3-lens-substrate-index.md still claimed SizeExpr replaces SizeVariable, but cost-lens design (post-ef21e1a00) had already retracted SizeExpr in favor of unified SymbolicCost. Cross-doc authority drift. Resolution (both BLOCKINGs): - Drop display_name field entirely from cost-lens + complexity-lens designs. - SizeVariable substrate stays UNCHANGED at { source_port: PortId }. - InternTable is the single canonical name authority — already populated at parse time keyed by port_id. Renderer reads via intern_table::name_of(source_port). - The "Named SizeVar" gap from the capability register is closed by renderer-side wiring (no substrate change), not by adding a field. - Master index updated: SizeVariable line replaces the old SizeExpr line; notes InternTable as name authority.

Fix: SectionedLensApplication<C> + ApplicationConfig<C> parametric in the lens carrier C; lens: Lens<C> and config.budget: C share the same C structurally. Mismatch is unrepresentable, not type-checker-rejected. Per-lens budgets dissolve into the existing Lens<C> carrier — no separate ComplexityBudget/CostBudget/ParallelismBudget carriers needed. BLOCKING #2: complexity-lens Certainty composed independently from cost dominance. Fix: define joint compose_summary function (§3.1) where certainty composition is cost-aware — when dominance drops a cost component, that component's certainty does NOT enter the result. Surfaces v2's implicit Θ(n²) Proven semantics; cost-unaware certainty would diverge from v2 on the cementing fixture corpus. BLOCKING #3: effect-enumeration line 17 prose still claimed signature is "one structural authority" for effects. Fix: updated to name the two orthogonal authorities — signature for effect SET, algebra inhabitance for effect KIND. Aligned with §2.4 + §8.1 that I'd already fixed at 92d9b11cf. BLOCKING #4: sibling lens docs and tests-as-data didn't share one cementing closure shape — complexity + effect proposed Rust cementing tests, cost (after my earlier fix at ef21e1a00) proposed QuantifiedTestClaim. Inconsistency. Fix: align all three on **Rust cementing today + dissolution trigger to tests-as-data step 5 .dag port**. Per-lens divergence is now explicitly forbidden in the master index. NB1: cost-lens §1.4 still said "single field addition" / "Rust mirror single field add" after the InternTable fix removed the field add. Cleaned up to "renderer-only, no substrate change". NB2: tests-as-data §3 said "17 variants" but enumerated 22 (Compiles ... BridgeLedgerZero). Fixed count to 22.

All updated to reflect the parametric resolution (per §2): - ApplicationConfig<C> parametric in lens carrier C; lens/budget pair is structural via shared C. - Mismatch is unrepresentable, NOT type-checker-rejected. - No budget_type field on Lens<C>; the parameter C IS the structural authority. - Each lens's existing Lens<C> carrier IS the budget type; no new per-lens budget carriers.

This re-creates EXACTLY the illegal-states-representable pattern that the §2 ApplicationConfig sum-type fix dissolved (the original finding at design-lens-application- surface.md:43 from a prior wave). Fix: dissolve the optional field. The cascade-flip (T-Lens-Behavioral- Parity COMPLETE flipping default complexity from Introspect to Enforce) is purely SYNTHESIZER-side, not substrate-side: - Pre-cascade: synthesizer emits `Introspect` for every default complexity application. - Post-cascade: synthesizer emits `Enforce { budget: <computed class>, diagnostic_severity: Error }` — the computed class IS the regression baseline; the variant choice carries the fact structurally. No optional field on the carrier. The cascade just changes which variant the synthesizer constructs. Same illegal-states-unrepresentable discipline as §2. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): drop certainty_lattice — Certainty composition is cost-aware, not lattice-fold Cursor BLOCKING at sha 98f2fc4f line 196: join_certainty's "Proven wins under alternative" semantic was P1 unfaithful — a Proven branch arm could hide a Conservative arm carrying the actual worst-case bound, so the result's certainty would no longer faithfully describe the bound it qualifies. Same cost-unaware pattern as the §3.1 BLOCKING from earlier in the wave (composition independent from cost dominance). Resolution: drop the BoundedLattice<Certainty> declaration entirely. Certainty does NOT compose via lattice meet/join; composition is cost-aware per §3.1 compose_summary_* family. The lattice declaration was misleading — it suggested an independent composition pattern that contradicts the cost-aware design. Updates: - §1.5: removed `data certainty_lattice` declaration + meet_certainty + join_certainty function bodies. Replaced with prose explaining cost-aware composition + tightness-ordering distinction (ordering is implicit when projecting; not a composition operation). - §3.1: meet_certainty(...) call → meet_pair(...) inline helper, with explicit comment that it's used ONLY when both contributions survive cost composition (NOT a free-standing lattice op). - §11 cascade-gate list: removed "data certainty_lattice" from the class-5-grammar dependent declarations list with explanatory note. Same illegal-states-unrepresentable + cost-aware-composition discipline preserved end-to-end across the §3.1 + §1.5 + §3.x compose_summary_* chain.

This contradicts §2.4's locked rule that effect KIND is declared only via algebra inhabitance (inhabits IdempotentRead<R>), NOT derived from signature shape — same modeling-discipline violation as the line 151 BLOCKING from the prior wave (cursor BLOCKING #2 of this codex-wave). Resolution: rewrite §8.4 to derive readonly's deletion rationale from algebra inhabitance, not signature shape: - After migration, read kind is declared via `inhabits IdempotentRead<R>` on the callable (per §2.4 + §8.1) — structural fact. - The `readonly` keyword duplicates that inhabitance: same fact, two carriers. P2 single-authority + feedback_no_annotations forbid this. - Keyword is redundant AND drift-prone (feedback_state_space_vs_ behavioral_invariants: keyword could disagree with inhabitance). - Implementation-mechanical: every operation currently using `readonly` already has a corresponding `inhabits IdempotentRead<R>` declared at the migration site (one-to-one mapping in the atomic PR per §6). The §2.4 → §8.1 → §8.4 chain is now consistent end-to-end: signature carries effect SET; algebra inhabitance carries effect KIND; the readonly annotation is the same parallel-authority bug pattern P5/P2 forbid.

Tightened to commit to the stronger claim: cementing asserts structural equivalence on the FULL SymbolicCost/CostExpr carrier shape (not a projection). Asymptotic-class equivalence is a downstream consequence, not a substitute. Aligns with the structural_equivalent() function shape already declared at line 318. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): remove implicit Enforce-with-inferred-baseline; align Certainty no-lattice references Codex BLOCKING on PR #1488 sha 265d8ef7: §8.3 + §3.2 + §5.1 said the default complexity application post-cascade flips to Enforce mode with "budget = computed asymptotic class at synthesis time" — but the synthesizer recomputes from the current body each compile, so the baseline moves with the body. Whatever class the function has becomes both "current" and "baseline"; they always agree; no regression ever fires. The fact the design claimed to enforce was lost on every recompile. P2 single-authority + facts-flow-forward violation. Resolution: remove the implicit Enforce mode entirely. Default is Introspect-only for unannotated functions; user explicitly authors Enforce { budget: <chosen class>, ... } to opt into enforcement. No auto-inferred baseline — those would need persisted authority (either generated source, forbidden by feedback_no_generated_code_on_disk, or sidecar files, same problem). The structural answer: complexity contracts are user-authored. Re-framing "opt-out for complexity" per the original user directive: the user can opt out (by not authoring an Enforce application or by authoring Introspect); compile errors fire when the user opts IN with a budget the actual function exceeds. ComplexityBudgetWaiver retains its purpose — accepting known violations of explicit user contracts. Codex NB: residual references to "Certainty + lattice declaration" / "two new lattice instances" in complexity-lens lines 535 + 579 didn't match the §1.5 lattice deletion. Updated both to single BoundedLattice<AsymptoticClass> instance + Certainty 2-variant sum WITHOUT lattice (composition is cost-aware via §3.1 compose_summary_*). Updates: - §3.2 (Default policy): full reframe to user-driven contracts. - §5.1 (Default-application synthesis): synthesizer never emits Enforce; only Introspect for unannotated functions. - §8.3 (Default-application semantics): RESOLVED with new framing — user-driven contracts; no implicit baseline; explicit rationale for why generated-source is not the answer. - complexity-lens §5 step 2 + §7.4: drop "Certainty + lattice declaration" and "BoundedLattice<Certainty>" from the substrate-landing list and ROADMAP-P2 dissolution accounting. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): lens-application — add LensEnforcement<Output, Budget> projection carrier Codex BLOCKING on PR #1488 sha 265d8ef7 line 100: tying ApplicationConfig<C> to the same C as Lens<C> made the complexity lens budget = AsymptoticClass, but the complexity-lens design publishes Lookup<ComplexitySummary> with work/span/certainty as the lens output. Either drop downstream facts (force output = AsymptoticClass) or contradict the lens-output contract (output = ComplexitySummary; budget = AsymptoticClass; type system can't enforce compatibility). P1 modeling faithfulness + facts-flow-forward violation. Resolution: introduce LensEnforcement<Output, Budget> projection carrier in §2. Each lens declares both: - Lens<Output> for the read function (rich output type — load-bearing for lens-fold composition per compose_summary_*) - LensEnforcement<Output, Budget> for the projection from Output to the budget-comparable type (identity for cost; summary.asymptotic_class for complexity) SectionedLensApplication<Output, Budget> is parametric in BOTH parameters; the type system enforces lens/projection/budget compatibility through the shared Output and Budget. Mismatched triples (e.g., complexity-lens with SymbolicCost budget) are unrepresentable. Why projection rather than single-carrier: the lens output for complexity is rich (ComplexitySummary {work, span, asymptotic_class, certainty}) — required by §3.1 compose_summary_* composition. The budget is simple — the user's "function should be O(log n)" contract. Forcing budget = output over-constrains user authoring; forcing output = budget drops facts the composition needs. The projection separates the concerns. Updates: - §2: introduce LensEnforcement<Output, Budget>; SectionedLensApplication becomes parametric in (Output, Budget). Worked examples for all 4 lens enforcements added. - §3: ApplicationConfig<Budget> (was <C>); narrative updated to reference Output + Budget pair. - §6: Substrate Manager scope expanded to include LensEnforcement declarations. - §9 (NOT-modify list): per-lens budget types now declared via LensEnforcement, not via shared C. - §10 step 1: closure gate adds lens_enforcement_carrier_landed; substrate authoring includes per-lens LensEnforcement declarations. - design-r3-lens-substrate-index.md substrate-authority table: updated to list the 4 parametric carriers.

But §3 + line 129 said Introspect has "no projection or comparison" — leaving Introspect carrying enforcement metadata it cannot consume. P2 / illegal-states-unrepresentable: an Introspect application should not have enforcement axes. Resolution: split into two carriers + sum: - EnforcedApplication<Output, Budget> — carries lens, enforcement, section, budget, diagnostic_severity, span. Both type parameters relevant. - IntrospectApplication<Output> — carries only lens, section, span. No Budget axis, no enforcement projection. - SectionedLensApplication = Enforce<O,B>(EnforcedApplication<O,B>) | Introspect<O>(IntrospectApplication<O>) — sum where each variant carries exactly its required parameters. Now Introspect cannot accidentally carry enforcement state; mismatched triples (lens, projection, budget) remain unrepresentable for Enforce applications. Both illegal classes structurally rejected. BLOCKING #2 (cost-lens line 332): residual paragraph still said "The QuantifiedTestClaim runs..." asserting equivalence on asymptotic class only — contradicted line 312's "Rust cementing test today" + line 316's "full SymbolicCost/CostExpr structural equivalence" Band-C parity claim. Two incompatible closure-gate authorities in same section. Resolution: rewrote line 332 to align with Rust cementing + full SymbolicCost/CostExpr structural equivalence. Single authority restored. Also updated downstream references: - §3 narrative: ApplicationConfig sum-type declaration removed (folded into EnforcedApplication directly per §2). Pairing semantics still documented; the carrier shape is the single authority. - §3.2 ComplexityBudgetWaiver rationale: updated to "an Introspect application" instead of "SectionedLensApplication { config: Introspect }". - §4.1 worked example: substrate-after-parsing block now uses Enforce<ComplexitySummary, AsymptoticClass>(EnforcedApplication { ... }) with all coordinates explicit. - §5.1 default synthesis: synthesizer emits Introspect<ComplexitySummary>(IntrospectApplication { ... }). - §6 substrate-owner scope: 5 carriers now (was 4 before split). - §10 step 1: closure gates updated; substrate authoring includes per-variant carriers + per-lens LensEnforcement declarations. - master index substrate-authority table: row updated to reflect the carrier split. - r3-structure.md rows 40 + 148: lane-row carriers list updated to match the per-variant shape.

Parallel prose authority for the same decision violated P2 (single authoritative description) — r3-structure summary contradicted the canonical owning design doc. Fixed both occurrences to match the resolved framing: - Unannotated functions: synthesized Introspect-only. - Enforcement: requires explicit user authoring of apply_lens with Enforce + budget. - "Opt-out" reframed: user can opt out (no Enforce / explicit Introspect); compile errors fire when user opts IN with a budget the function exceeds. - ComplexityBudgetWaiver preserved purpose: accepting known violations of explicit user contracts.

The check would have been API-level convention (the fold-pass hardcoding "use lattice ordering for AsymptoticClass / dominance for SymbolicCost / mode-mismatch for ParallelismMode" instead of reading declared facts). P2/P6 single-authority + API-level-enforcement violation. Resolution: extend LensEnforcement<Output, Budget> to carry both the projection AND the violation relation: ```dag type LensEnforcement<Output, Budget> { project: Output -> Budget violates: (declared: Budget, observed: Budget) -> Bool } ``` Each per-lens enforcement declares its own violation semantics structurally: - complexity_enforcement.violates: lattice ordering on AsymptoticClass - cost_enforcement.violates: dominance ordering on SymbolicCost (observed dominates declared) - parallelism_enforcement.violates: mode-mismatch (OptInIndependent declared but lens computed Sequential = violation) The fold-pass dispatch reads the per-lens violation relation directly (no hardcoded comparison logic in the fold-pass; the dispatch is fully substrate-driven). Updates: - §2 LensEnforcement carrier definition: extended with violates field + rationale. - §2 per-lens enforcement examples: each declares both project and violates. - §4.1 worked example "Compiler-side processing": fold-pass description reads enforcement.project then enforcement.violates. - §5 lens-fold integration step 2: dispatch reads project + violates.

Span has independent dominance from work (different inputs to iterate — span uses outer.work + body.span, while work uses outer.work + body.work). A conservative span contributor could be dropped from work's dominance walk while its span bound survived in span's dominance walk — the surviving span contributor's certainty would not enter the result's certainty. P1 modeling faithfulness + facts-flow- forward: certainty no longer faithful to the bound it qualifies on the span dimension. Resolution: per-dimension cost-aware certainty composition. Each dimension (work, span, future per-DB-3) computes its own surviving- contributor certainty independently; the result certainty is the meet across dimensions (any unproven dimension makes the whole result unproven). ```dag let work_cert = certainty_of_surviving_per_dim(outer, body, outer.work, body.work, composed_work) let span_cert = certainty_of_surviving_per_dim(outer, body, outer.work, body.span, composed_span) let composed_certainty = meet_pair(work_cert, span_cert) ``` certainty_of_surviving_per_dim is generalized to take per-dimension inputs (outer's contribution to this dimension, body's contribution, the composed dimension result) and walks dominance specifically on that dimension. Updates: - §3.1 compose_summary_iterate: per-dimension certainty composition with explicit work + span tracking. - §3.1 certainty_of_surviving renamed to certainty_of_surviving_per_dim; signature parameterized over dimension. - §3.1 compose_summary_sequential / compose_summary_branch comments updated to name the per-dimension pattern. - §1.5 (Why no BoundedLattice<Certainty>): updated to reference certainty_of_surviving_per_dim and per-dimension composition.

But callable_arrow_effect TODAY derives effect kind from signature/body shape — if the body stays unchanged, it does NOT consume the new inhabits IdempotentRead<R> / inhabits Mutating<R> facts. Facts-flow-forward / P2 violation: new substrate authority not consumed by downstream. Resolution: the lens body MUST change in its kind-classification dispatch. Specifically: - The fold STRUCTURE (per-callable walk + report aggregation) is unchanged. - The per-callable kind classifier IS rewritten — from signature/body shape inference to algebra-inhabitance lookup (callable_inhabits(callable, idempotent_read_for(resource)) / callable_inhabits(callable, mutating_for(resource))). Updates: - §6.2 first reason: lens body framing flipped from "does not change" to "changes only in its kind-classification dispatch", with explicit rationale citing this BLOCKING. - §9 NOT-modify list: lens fold STRUCTURE preserved; per-callable kind classifier explicitly listed as modified (with cross-reference). - §9 size estimate: "lens-fold itself is unchanged" → "lens-fold structure is unchanged; per-callable kind classifier rewrite is S". - §10 implementation order: NEW step 5 ("Lens kind-classifier rewrite") inserted between OperationEffect retirement (step 4) and cementing test (now step 6). Total steps 6 → 7; steps-summary paragraph updated. Facts-flow-forward restored across the full migration: new inhabitance authority lands → lens classifier reads it → effect kind facts flow into ReadShaped / WriteShaped lens output. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): add lens_enforcement_carrier_landed to r3-structure lane gates gpt-5-5-pro REQUEST_CHANGES on PR #1488 sha 85a6bb0e (BLOCKING #3): design-lens-application-surface §10 step 1 declared lens_enforcement_ carrier_landed as a closure gate, but the r3-structure.md lane summary (lines 40 + 148) omitted it from the authoritative gate list. Per "tracked vs untracked debt" discipline: a named substrate carrier (LensEnforcement<Output, Budget>) without a tracked landing gate in the roadmap leaves new substrate work outside the closure-receipt mechanism. Resolution: add lens_enforcement_carrier_landed to both lane-summary gate lists (line 40 + line 148) with explanatory note that it covers the per-lens projection + violation-relation declarations co-located with each lens. (BLOCKINGs #1 + #2 from same review wave at sha 85a6bb0e are already addressed at e554f85e6 — LensEnforcement carries both project AND violates per-lens violation relation; substrate authority for budget-exceeded check is structural, not API-level.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): §8.5 implementation note — read EnforcedApplication.budget, not config.budget Codex BLOCKING on PR #1488 sha a525baf0: §8.5 still pointed implementers at `config.budget`, but the per-variant split at 968994843 dissolved ApplicationConfig — budget now lives on EnforcedApplication<Output, Budget> inside the Enforce variant of SectionedLensApplication. Stale implementation guidance pointing at non-existent authority. P2 violation. Fixed: §8.5 now describes the lens-fold matching on Enforce(EnforcedApplication { budget, ... }) and the Introspect case (no budget). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): effect-enumeration lens body reads signature directly, not via LensEnforcement Cursor BLOCKING on PR #1488 sha c41b8ce8 line 373: my §6.2 fix said the new effect_enumeration lens body "reads enforcement.project for the effect set". But LensEnforcement is the lens-application-surface budget-projection carrier (T-Lens-Application-Surface lane). The effect-enumeration lens body is part of T-Lens-Behavioral-Parity slice 4 — which CASCADES into T-Lens-Application-Surface (the latter gates on the former being COMPLETE). Reading enforcement.project from the lens body inverts the cascade AND gives the effect-set fact a second authority (signature-derived per §2.4(a) vs LensEnforcement projection). Resolution: lens body reads effect set DIRECTLY from the callable's arrow signature (existing substrate query — resource types in input ∩ output, per §2.4(a)). Kind classification reads callable_inhabits(...) per §2.4(b). Both queries are within T-Lens-Behavioral-Parity slice 4 scope; neither depends on LensEnforcement. Updated §6.2 line 373 to: - Replace "reads enforcement.project for the effect set" with "reads the effect set directly from the callable's arrow signature (existing substrate query; structurally derivable per §2.4(a) without any lens-application-surface artifact)". - Add explicit "neither depends on LensEnforcement from T-Lens- Application-Surface (cascade flows the other direction)". Cascade direction preserved: T-Lens-Behavioral-Parity COMPLETE → T-Lens-Application-Surface, not vice versa. Effect-set fact has single authority (signature query); kind fact has single authority (algebra inhabitance). No lens-application carriers consumed by lens body. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): per-coordinate certainty on ComplexitySummary (no global collapse) Codex BLOCKING on PR #1488 sha 75a6ab57: §3.1 computed independent work_cert and span_cert per-dimension, then immediately collapsed them into one global ComplexitySummary.certainty via meet_pair. That collapse loses the per-dimension proof-tightness fact: if work is Proven but span is Conservative (or vice versa), downstream display/enforcement consumers see only "globally Conservative" and cannot know the work bound was proven. P1 modeling faithfulness + P2 facts-flow-forward violation: the certainty fact each dimension carries gets fused into ambiguity. Resolution: ComplexitySummary now carries per-coordinate certainty — work_certainty and span_certainty as independent fields. No global certainty field; no meet across dimensions. Each coordinate's certainty stays on that coordinate through composition. ```dag type ComplexitySummary { work: SymbolicCost span: SymbolicCost asymptotic_class: AsymptoticClass work_certainty: Certainty // per-coordinate per BLOCKING fix span_certainty: Certainty } ``` Updates: - §1.7 ComplexitySummary declaration: split certainty into work_certainty + span_certainty with explicit rationale citing this BLOCKING. - §3 ComplexitySummary declaration in lens body section: same split. - §3 outer Loop construction: outer.span = outer.work, so both certainties = bound_cert. - §3.1 compose_summary_iterate: drop the global meet across dimensions; work_certainty := work_cert, span_certainty := span_cert independently. - §3.1 certainty_of_surviving_per_dim signature: takes per-dimension certainty inputs (outer_cert, body_cert) explicitly; no global outer.certainty / body.certainty lookup. - §3.1 compose_summary_sequential / compose_summary_branch comments: pattern updated to "no meet across dimensions; per-coordinate independence preserved on output". asymptotic_class is still a projection of work; its certainty is work_certainty (no separate class_certainty since the class is derived, not independent). All facts faithful to the dimension they qualify. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): align lens-application doc with per-coordinate certainty (work_certainty / span_certainty) Cursor APPROVE_WITH_COMMENTS finding on PR #1488 sha 37f3bc62: lens- application-surface lines 125 + 152 still described ComplexitySummary with a single `certainty` field, but my fix at 955cafe2c split certainty into per-coordinate work_certainty + span_certainty in the complexity- lens design. Sibling-doc mismatch — same carrier shape described two ways across two design docs in the same PR. Updated lines 125 + 152 to match complexity-lens §1.7's per-coordinate shape: - Line 125 inline comment: "rich output: work/span/asymptotic_class/ work_certainty/span_certainty". - Line 152 narrative: "rich (ComplexitySummary { work, span, asymptotic_class, work_certainty, span_certainty } — per complexity- lens §1.7, certainty is per-coordinate to avoid collapsing per- dimension proof-tightness facts)". - "Forcing output = budget would drop work/span/certainty facts" → "drop work/span/per-coordinate-certainty facts". Cross-doc carrier-shape consistency restored. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: Gunbc PM * docs(r3): codex BLOCKINGs #1-3 (sha 37f3bc62) — substrate assumptions aligned with v3 reality 3 BLOCKINGs at sha 37f3bc62, all claiming docs lock substrate assumptions v3 cannot currently express: BLOCKING #1 (cost-lens SizeVariable label): doc said renderer reads via intern_table::name_of(port_id). Verified: src/v3/std/algebra.dag:143 explicitly says "InternTable lookup the lens doesn't yet run". v3 has some InternTable machinery (PR #367 Phase 1) but the port-id-to-name query is NOT landed. Cannot assume it. Resolution: re-introduce SizeVariable.display_name: String? as the single substrate authority for the user-facing name. No InternTable lookup assumed. Field is single-source (not parallel with anything); parser populates from authored binding names where present, None for inferred. Earlier "parallel authority" concern (gpt-5-5-pro at ef21e1a0) doesn't apply because there's no second source — InternTable lookup isn't landed and isn't claimed. BLOCKING #2 (per-variant generics): doc declared SectionedLensApplication = Enforce<Output, Budget>(...) | Introspect< Output>(...) — but v3 .dag sums use uniform type parameters across variants (e.g., Lookup<C> = Miss | Hit(C); both share C). Per-variant parameter binding / existential packaging not currently supported. Resolution: drop the SectionedLensApplication SUM. Use TWO SEPARATE top-level carriers — EnforcedApplication<Output, Budget> and IntrospectApplication<Output>. Lens-fold pass walks two separate lists and emits Diagnostics from Enforce walks, records values from Introspect walks. No per-variant generics required. Each lens application in .dag source is one or the other; user authoring chooses at apply_lens site. BLOCKING #3 (TestPredicate maturity): doc said "Today's TestPredicate coproduct covers 22 variants" listed by name, treating them as uniformly-live substrate. Per verification.dag inline annotations, many are 🟡 Scaffold with named dissolution triggers (ExecuteCommand, ForAllTargets, LensOutputEquals, DifferentialEquals, BinaryDimensionReportEquals, AlgebraicLaw, ReleaseDeferredClaim, SubstrateResearchDeferredClaim). Resolution: §1 explicitly disclose 🟢 TERMINAL vs 🟡 Scaffold partition; note that ports landing on Scaffold variants are inherently scoped by that variant's named dissolution trigger; new-carrier residual is in scope of T-Tests-As-Data-Completeness, not assumed live. Updates: - design-cost-lens §1.2: SizeVariable.display_name reintroduced as single authority; revert §1.4 from renderer-only to additive field; both wave reviews now reconciled. - design-lens-application-surface §2: SectionedLensApplication sum removed; two top-level carriers (EnforcedApplication + IntrospectApplication). Downstream §3 + §4 + §5 + §6 + §8.5 + §9 + §10 references updated to "two separate top-level carriers" framing. - design-tests-as-data §1: TestPredicate maturity disclosure (TERMINAL vs Scaffold partition with named dissolution triggers per verification.dag inline annotations). - design-r3-lens-substrate-index: substrate-authority table updated to drop "sum" and list two separate carriers. All three BLOCKINGs reflect the constraint: design docs cannot assume substrate facilities not yet landed, and cannot use shapes v3 cannot currently express. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): cementing test asserts per-coordinate certainty (work + span), not collapsed Codex BLOCKING on PR #1488 sha e3010014: §1.7 changed ComplexitySummary to per-coordinate work_certainty + span_certainty (closing the global- collapse bug at PR #1488 / 955cafe2c), but §4.1 cementing test still asserted a single global v3.certainty. Internally inconsistent: closure gate would not validate the per-coordinate claim §1.7 makes; the test would…
