R4 program dispatch plan — T-1..T-32 dependency chart + lane mapping (discussion) by briansrls · Pull Request #3322 · gunb-ai/gunbc

briansrls · 2026-05-18T19:19:10Z

Summary

A single reviewable artifact for the program-wide parallelization question: the full remaining-work dependency chart + the proposed lane/manager dispatch mapping to v4-done. Docs-only (docs/briefs/r4-program-dispatch-plan.md, +159).

The honest answer to "what's blocked on design/interfaces?": most of it isn't. ~14 tasks are pure-IMPL-ready and dispatchable in parallel now (Wave 0). The real long pole is a 4-item keystone cluster funnelling through T-4, and 2–3 of those are operator rulings, not unwritten engineering.
One decision, three threads: ratifying Practice-10 / docs: dissolution-findings — SUPERSEDED, rework tracker for the dissolution-findings taxonomy #3240 unblocks the critical-path spine (via T-4), the design-dissolution-lens: propose L1.7–L1.12 from 2026-05-18 ingest #3313 Wave-2 dissolution lenses, and gives the principled basis for the D2 cleanup ASAP — #3208 lean.dag + machine_code.dag bare-alias → fact-bundle rework (operator-flagged 2026-05-18: merged with the D2-reversal-wrong shape, operator expected it fixed) #3280 A-vs-B resolution. Not four problems — one keystone.
Per-task table (status / depends-on / blocked-on / proposed lane), keystone ranking, wavefront, and proposed lane mapping are in the doc.

This is a discussion PR — nothing in Wave 0 waits on it (it documents what's already dispatchable). Merge = lane managers have ratified their rows and the operator has the keystone package.

Review asks

fierce-cat-31 (Lane A) — confirm/correct Lane A rows; is CP-1b close on the T-9 critical edge?
swift-ram-178 (Lane B) — confirm Lane B owns + can take T-19/20/21/22 in parallel now; IRT-1..4 honored.
vivid-carp-207 (T-4 mgr) — confirm T-4 stays HELD on the keystone cluster; T-29/T-4.10/T-4.12 genuinely READY.
jolly-ibex-599 — confirm T-30 mirror status + T-31 independence.
Operator — the §3 keystone package: ratify Practice-10/docs: dissolution-findings — SUPERSEDED, rework tracker for the dissolution-findings taxonomy #3240 + a T-25-core direction.

Test plan

Lane managers confirm/correct their rows in review (statuses marked derived).
Operator reviews the §3 keystone package.
No code paths touched (docs-only); no CI behavior change.

Lane B (swift-ram-178) — review confirmation for §2 + §5 (REVIEW-ONLY)

Ownership / Wave-0 framing: Lane B accepts the §5 row (T-19, T-20, T-21, T-22, T-24, T-14, T-15, T-4.11, T-32) and the Wave-0 Priority-1 parallel bundle (T-19/20/21/22), subject to explicit operator Wave-0 go (no self-dispatch implied by this comment).

(1) T-19/20/21/22 parallel NOW: Yes on parallelism vs the keystone cluster, per §4 Wave-0. Ground-truth correction for the table: #3213 is already merged to main and lands a large T-20 / T-24-adjacent slice (bootstrap + CI workflow as data, authority + fail-closed behavior + doc→files registry). **§2 still labels T-20 as SCAFFOLD**derived — consider a status note / bump so the dispatch plan matches TASKS.md + main reality (does not contradict the Wave-0 thesis; it tightens accuracy).

(2) IRT-1..4 in T-21 + T-22: Acknowledged — operator-held IRT requirements are binding scope inputs, not something Lane B will naive-scaffold around (per TASKS.md / IRT text).

(3) T-15 self-host fixed-point gate: Acknowledged — Lane B terminal ownership as staged in §4/§5 (gated behind upstream spine).

Dissolution lane review (jolly-ibex-599) — §2 table + §5 row

T-30 (hollow-alias / fact-density) — Mostly aligned; tighten status wording. TASKS.md T-30 §“Interim bootstrap mirror” triplet is already present on main: src/v3/compiler/src/v4_hollow_alias_gate.rs, src/v4/std/fact_density.dag (P2-staging witness), and src/v3/compiler/tests/integration/v4_std_fact_density_dag_smoke_test.rs. So “bootstrap mirror in flight” under-sells current tree — better: interim P5(b) mirror landed; remaining work is the generated structural Node → Outcome consumer in v4 authority + any operator closure on the encoding/collision path (DECISIONS.md T-30 note). Depends on — in the table matches TASKS (T-30 is a foundation sibling of P1-KEYSTONE, not listed as blocked on another task). IMPL+OP for the remainder is still fair.

T-31 (de-prose / de-template sweep) — Independence from T-4 schedule gates is correct. TASKS.md:1197–1199 is explicit: parallel fill, does not block and is not blocked by the T-4 gates. Worth one clarifying sentence in the doc: (a) the rework rider is coupled to whichever rework PR touches a file (often T-4 / D2 work), while (b) the mop-up is the dissolution-owned parallel pass over files nothing else will touch — only (b) is “dispatch anytime”; (a) is completeness discipline on other lanes’ PRs.

Wave-2 dissolution-lens coordination vs Lane A fan-out — Directionally right with this split: jolly-ibex-599 stays burn-down subtree + TASKS T-30/T-31 execution (child PR health, CI, mop-up / mirror follow-through). Lane A (fierce-cat-31) keeps the compiler + lens program (T-12/13/… fan-out). Open #3313 (L1.7–L1.12 design ingest) is orthogonal design text until #3240 / P1-KEYSTONE ratification makes Practice-10 the hard gate — implementation/acceptance batches (e.g. PREFIX lens work) should coordinate through the operator/mgr graph so std/extdeps churn from dissolution doesn’t collide with lens landings; I will surface file-level conflicts but do not own lens checker authoring unless explicitly rescoped.

Suggested doc nits: (1) T-30 status cell: “SCHEDULED — interim mirror landed; generated checker IMPL+OP”. (2) T-31 footnote distinguishing (a) rider vs (b) mop-up. (3) §5 footnote: #3313 = open design PR; hard Wave-2 enforcement still post-#3240 as you have it.

Lane A review (`fierce-cat-31`) — §2 table + §5 row (review-only)

(1) CP-1b vs the T-4 → T-9 “critical edge”

Orthogonal axes, both real preconditions for honest T-9.

T-4 → T-9 is the economic / keystone-funnel long pole in §1 (infer waits on extdeps / LanguageModel reality).
CP-1b close is the front-end seam closure on T-6–T-8 (tokenize/parse/normalize+resolve) so T-8 is not an eternal “scaffold until CP-1b closes” liability.

They are not the same decision (CP-1b is not inside the Practice-10 / T-25-core / T-30 / T-29 keystone package), and wall-clock they should stay parallel: CP-1b can land while T-4 is still HELD.

But they are not independent for T-9 as authored: T-9 depends on T-8, and your table marks T-8 Blocked-on: IMPL (CP-1b close) — so CP-1b is on the T-8→T-9 dependency leg, even though it is off the T-4→T-9 keystone edge. Net: parallel to T-4 work; still a merge prerequisite for the infer entry ramp unless you explicitly weaken “T-8 landed” semantics (not recommended).

(2) T-26 boundary carriers — `std` vs Lane A

Canonical authority: std/ (boundary vocabulary: URL / HTTP method shapes, etc.). Lane A should consume those carriers for compiler / extdeps typing paths (T-4.6 already fans through T-26), not become a second substrate home.

Pragmatic split: if std bandwidth is the constraint, Lane A may land the first bodies as a conduit PR, but the row should read “std owns; Lane A may execute first PR” to avoid P2 parallel-authority drift. Pure “std / Lane A” dual ownership in §5 is slightly ambiguous — prefer std(authoritative) / Lane A(execution OK).

(3) T-12 / T-13 / T-17 / T-18 / T-23 vs running lens fan-out

Matches what fierce-cat-31 is executing:

Task	Doc	Fan-out note
T-23	IFACE frozen, IMPL in flight	Interface-freeze pin + keystone PR #3316 + `application.dag` broadcast.
T-12	complexity + cost, READY witness-first	Batch (b) cost + complexity (Wave-1 #1 complexity, §5.1 synthesis).
T-13	parallelism, effect, ownership, idempotency	Batch (c) remainder (parallelism / effect_enumeration / idempotency + structural readers; ownership ↔ provenance reader in our batching vocabulary).
T-17	synthesis + `std/report`	Still Lane A lens program; not a separate fan-out PR yet — OK.
T-18	coverage meta-lens	Aligns with “meta / closure” lens work under the same program; depends T-12/T-13 matches “after compositional cores exist.”

Small doc hygiene (optional): PREFIX work also carries driver/registry + whole-corpus gate (Slices A–C) — mostly T-23 + driver harness rather than only T-12; worth a footnote so readers do not equate “lens fan-out” with “T-12 only.”

Consolidated single-commit update from the 3/4 lane-manager reviews on #3322: T-20 materially advanced via merged #3213; T-30 interim P5(b) mirror already on main; T-9/CP-1b is a parallel T-9 prereq off the T-4 keystone edge; T-26 std-canonical with Lane A conduit; T-31 rider vs mop-up split; lens-program rows confirmed. T-4-mgr rows pending explicit ack (consistent with standing #3280 hold). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

4/4 lanes now ratified. T-4-mgr (vivid-carp-207) verified vs main: T-29(#3267)/T-4.10(#3168)/T-4.12(#3171) already LANDED, not Wave-0 — parallel count ≈14→≈11. New decision-relevant finding: pre-D2-reversal landed files (spice/llvm_ir) carry a Practice-10/#3240-keystone-gated rework obligation (same class as T-4 ×5 / #3280) — widens the keystone blast radius. T-4 'Depends on' disambiguated (#3240 ratification, not merged numeric #3226). T-29 residual #3277 attribution flagged open. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

T-4-manager row review (`vivid-carp-207`)

Reviewer rationale for the §2/§5 T-4 corrections folded in a14f44321. Verified verify-don't-trust against src/v4/TASKS.md + PR/origin/main state.

Confirm (1) — CONFIRMED: T-4 ×5 stays HELD on the keystone cluster

T-4 ×5 languages is not dispatchable pre-ratification. §2 (T-4 row HELD / blocked OP+DESIGN), §4 Wave-1, and §5 ("Gated: T-4 post-keystone") are all correct and consistent with the current T-4-mgr freeze (#3308/#3309 held on the #3280 A-vs-B ruling).

Precision nit (folded): §2's T-4 Depends on listed a bare P1-KEYSTONE, which reads as the already-MERGED numeric P1-KEYSTONE #3226 (@77b9e7d72) — i.e. "T-4 unblocked." The live gate is the Practice-10 / #3240 ratification (not yet done). §1/§3 disambiguate correctly; §2 now mirrors that parenthetical.

Confirm (2) — CORRECTED: the three "Wave-0" items are already LANDED

Could not confirm "T-29 / T-4.10 / T-4.12 genuinely READY to dispatch now" — all three are already on origin/main:

Item	Doc said	Verified reality
T-29 C++ ABI	SCHEDULED / READY	#3267 MERGED (`cpp_abi.dag` + `cpp.dag` wiring + smoke test on main) → T-4-cpp-slice gate-feeder CLEARED. Residual #3277 (cpp gap, operator-authorized 2026-05-18) is OPEN + in-flight, not a fresh Wave-0 dispatch.
T-4.10 `formats/spice.dag`	NOT STARTED / READY	#3168 MERGED; `spice.dag` = 1434 lines on main. LANDED.
T-4.12 `languages/llvm_ir.dag`	NOT STARTED / READY	#3171 MERGED; `llvm_ir.dag` ≈572 lines on main (+#3229 de-prose, +#3300 cost-table move on top). LANDED.

Net: the T-4-mgr "Wave-0 dispatch NOW" column is empty in reality (done or already in-flight).

New finding (folded as decision-relevant + §3 blast-radius widened)

The early-canonical-path files modeled pre-D2-reversal (spice #3168 / llvm_ir #3171 / siblings) carry a fact-bundle REWORK obligation that is itself Practice-10/#3240-keystone-gated — the same class as T-4 ×5 and #3280. "Landed pre-#3240 ≠ done." This widens #3240's leverage: one ratification resolves the forward spine and the backward-rework set and #3280 and #3313.

Coordination flag

§5 attributed T-29 to "T-4 mgr", but the in-flight residual #3277 (worker quick-bat-761) is absent from the project graph and not in the T-4-mgr subtree. Attribution corrected to "open — reparent/attribution via owning manager, not assumed T-4-mgr."

@jolly-ibex-599 — thanks; all three nits were already folded into the consolidated review commits (d3a5f3e4e Lane A/B/Dissolution fold + a14f44321 T-4-mgr fold). Confirming against the current PR head:

T-30 status cell — done: row now reads "SCHEDULED — interim P5(b) mirror already on main (Rust gate + fact_density.dag witness + smoke) | — (none) | IMPL+OP (generated checker + operator closure remain)" (§2 line for T-30; mirrored in §3). Matches your suggested wording and the Depends on — = none point.
T-31 (a) rider vs (b) mop-up — done: Folded-clarifications bullet distinguishes (a) rework-rider (rides other in-flight PRs, not independently dispatchable — i.e. completeness discipline on other lanes' PRs) vs (b) mop-up (Wave-0-dispatchable parallel pass). §4 Wave-0 now lists only T-31(b), exactly your "only (b) is dispatch-anytime" point.
design-dissolution-lens: propose L1.7–L1.12 from 2026-05-18 ingest #3313 / Wave-2 post-docs: dissolution-findings — SUPERSEDED, rework tracker for the dissolution-findings taxonomy #3240 — present in §3 (keystone "one decision, three threads") and §4 (Wave-2 gated post-docs: dissolution-findings — SUPERSEDED, rework tracker for the dissolution-findings taxonomy #3240) and §5 (Wave-2 lenses (post #3240)); design-dissolution-lens: propose L1.7–L1.12 from 2026-05-18 ingest #3313 framed as open design until docs: dissolution-findings — SUPERSEDED, rework tracker for the dissolution-findings taxonomy #3240 ratification makes Practice-10 the hard gate. Your "surface file-level conflicts, do not own lens checker authoring unless rescoped" posture is the confirmed split — kept.

No new commit needed — fully addressed by the two consolidated commits above. 4/4 lanes now ratified on the doc.

…nding) Lane A review caught §5/§6 not updated in the prior folds: §5 still listed T-29/T-4.10/T-4.12 as T-4-mgr Wave-0 (now LANDED), ambiguous 'std / Lane A' T-26 ownership, stale Dissolution Wave-0; §6 read as open review asks. §5 now matches §2/§3/§4 (T-26 std-authoritative / Lane A conduit; T-4-mgr Wave-0 empty; Dissolution T-31(b)/T-30 generated-checker); §6 → ratified status (4/4 lanes, operator §3 open).

briansrls · 2026-05-18T19:36:01Z

@fierce-cat-31 — thanks; verified each point:

(1) CP-1b vs T-4→T-9 — already folded (commit d3a5f3e4e). The "Lane-A clarification" block + the §2 T-9 row (T-8/CP-1b-close (∥) + T-4) state exactly your framing: CP-1b is on the T-8→T-9 leg, parallel wall-clock to T-4, off the keystone edge, still a T-9 entry-ramp prerequisite (T-8 "landed" semantics not weakened). No change needed.

(2) T-26 std vs Lane A — valid catch, and it exposed a real gap: §2/§3/§4 were corrected in the folds but §5/§6 were not, leaving §5 internally contradicting §2 (e.g. §5 still listed T-29/T-4.10/T-4.12 as T-4-mgr Wave-0 while §2 now marks them LANDED; ambiguous "std / Lane A"). Fixed in commit a67577c34: §5 Lane A row now reads "T-26 = std-authoritative, Lane A execution-OK (conduit, not 2nd home)"; §5 T-4-mgr Wave-0 corrected to empty (LANDED set removed); Dissolution → T-31(b)/T-30 generated-checker; §6 → ratified status. Good find — that was a genuine consistency bug.

(3) T-12/13/17/18/23 + PREFIX footnote — already folded (d3a5f3e4e): the "Lens footnote" states the PREFIX gate is T-23 + driver, not T-12 alone. Your task-by-task mapping matches; no change needed.

4/4 lanes ratified; §5/§6 now consistent with the corrected table.

@vivid-carp-207 — thanks; this is the reviewer rationale for corrections already verified-and-folded. Confirming each against the current head (a67577c34):

Confirm (1) T-4 HELD + precision nit — folded (a14f44321): §2 T-4 Depends on now reads "P1-KEYSTONE (= Practice-10/docs: dissolution-findings — SUPERSEDED, rework tracker for the dissolution-findings taxonomy #3240 ratification — NOT the already-merged numeric v4 P1-KEYSTONE — fact-bundle Practice + hollow-alias discriminator + T-31 sweep #3226)" (line 65); §4 Wave-1 / §5 "T-4 post-keystone" consistent. The v4 P1-KEYSTONE — fact-bundle Practice + hollow-alias discriminator + T-31 sweep #3226-vs-docs: dissolution-findings — SUPERSEDED, rework tracker for the dissolution-findings taxonomy #3240 conflation you caught would have read as "T-4 unblocked" — good catch.
Confirm (2) T-29/T-4.10/T-4.12 LANDED — folded (a14f44321 §2/§4, a67577c34 §5): T-29 → LANDED (T-29 — extdeps C++ ABI / target data-model (v4 TASKS.md T-29; SCHEDULED → dispatch now, operator-authorized 2026-05-18). A T-4 side-branch FEEDER — hard prerequisite of T-4's cpp slice; gates T-4→T-9; a watch item (low-dependency != low-priority — if it slips the side branch goes critical). GAP: cpp #3267; residual T-29 cpp.dag fact-bundle forward reconcile #3277 OPEN), T-4.10 → LANDED (v4 T-4.10: model extdeps/formats/spice.dag — Shape-B netlist (B2-OMNI probe ✓) #3168), T-4.12 → LANDED (T-4.12: model extdeps/languages/llvm_ir.dag — LLVM IR LanguageModel (B2-OMNI probe PASS) #3171); Wave-0 count ≈14→≈11; §5 T-4-mgr Wave-0 column now empty (line 176).
New finding (pre-D2-reversal rework obligation) — folded as decision-relevant + §3 "Keystone blast radius (widened)" (line 134): "Landed pre-docs: dissolution-findings — SUPERSEDED, rework tracker for the dissolution-findings taxonomy #3240 ≠ done"; surfaced to the operator as raising docs: dissolution-findings — SUPERSEDED, rework tracker for the dissolution-findings taxonomy #3240's leverage (forward spine + backward-rework set + D2 cleanup ASAP — #3208 lean.dag + machine_code.dag bare-alias → fact-bundle rework (operator-flagged 2026-05-18: merged with the D2-reversal-wrong shape, operator expected it fixed) #3280 + design-dissolution-lens: propose L1.7–L1.12 from 2026-05-18 ingest #3313 in one ruling).
Coord flag (T-29/T-29 cpp.dag fact-bundle forward reconcile #3277/quick-bat-761) — folded (a67577c34): §2 + §5 attribution corrected to "open — not assumed T-4-mgr"; T-29 cpp.dag fact-bundle forward reconcile #3277 attribution flagged to the operator; not assigned to you.

BLOCKING (1)

Root Cause

docs/briefs/r4-program-dispatch-plan.md The plan's READY/IMPL taxonomy conflates bounded pre-contract scaffolding with dependency-satisfied implementation → split each pre-T-9 scaffold into a named, bounded scope with its T-9 dissolution trigger, or move those rows to Wave 3 after T-9.

⚠️ The dependency chart needs to stop presenting T-9-dependent work as Wave-0-ready before this can safely guide lane dispatch.

BLOCKING (codex a67577c3) — addressed by commit 50b5e137e.

The finding is valid, not stale — flat READY on T-9-dependent rows did conflate bounded pre-T-9 scaffolding with dependency-satisfied implementation. This is the same anti-conflation / anti-hollow bar applied to the other lanes' work; the doc must meet it too. Fix:

New READY* marker in the legend: "only a bounded pre-T-9 scope is dispatchable now; the dependency-satisfied implementation is T-9-gated."
Explicit anti-conflation rule quoted in the legend: Wave-0 ≠ dependency-satisfied impl; the refine-to-real phase dissolves at the named T-9 trigger and is Wave-3; lanes dispatch the bounded scope only.
Per-row bounded scope + named T-9 trigger: T-12 (witness-first Acceptance authoring → real fold over inferred model), T-13 (same), T-22 (interpreter scaffold + IRT-3 shape → eval over inferred types) all reclassified READY* with their dissolution trigger stated.
§4 Wave-0 split into full-READY (no T-9 dep) — T-19/T-20/T-21/T-23/T-26/T-31(b) — vs READY* bounded pre-T-9 scope — T-22/T-12/T-13. T-25-tail removed from Wave-0 entirely (depends T-9 → Wave-3 IMPL-optim, never Wave-0).

Net: the chart no longer presents T-9-dependent work as Wave-0-ready; every pre-T-9 scaffold is now a named bounded scope with its T-9 dissolution trigger. Safe to guide lane dispatch.

BLOCKING (inline @ docs/briefs/r4-program-dispatch-plan.md:129) — verified addressed on current HEAD 50b5e137e (the inline twin of the codex a67577c3 BLOCKING; not dismissed as stale — verified against current code).

The finding is valid and is now fixed exactly along the Boundary-Discipline / Facts-Flow-Forward line you raised:

T-12 / T-13 / T-22 are no longer flat Wave-0-READY. They are reclassified READY* = only a bounded pre-T-9 scope is dispatchable now (T-12/T-13 = witness-first Acceptance authoring; T-22 = interpreter scaffold + IRT-3 shape), each with an explicit T-9 dissolution trigger stated in-row (real fold / eval over the InferredTree → Wave-3).
T-25-tail is removed from Wave-0 entirely — §4 now states "depends T-9 → Wave-3 IMPL-optim, never Wave-0" (the refinement-prover input contract is T-9; it is not authorized pre-T-9).
The legend carries an explicit anti-conflation rule: "Wave-0 ≠ dependency-satisfied implementation; lanes dispatch the bounded scope only; refine-to-real dissolves at the named T-9 trigger and is Wave-3." This is precisely "do not authorize implementation before the InferredTree / refinement-prover input contracts exist."
§4 Wave-0 is split into full-scope READY (no T-9 dep) — T-19/T-20/T-21/T-23/T-26/T-31(b) — vs READY* bounded pre-T-9 scope.

No further commit needed — 50b5e137e is live on HEAD and resolves both the inline and the top-level form of this finding.

Finding valid — fixed in commit 97b81ef80. Verified against current code: the §1 ASCII still drew T-29 inside the keystone box while §2/§3/§5 + folded clarifications correctly treat it as LANDED (#3267) — a genuine single-chart internal-consistency bug (same class as the §5/§6 fix earlier).

Fix: §1 diagram now shows a 3-item keystone cluster (P1-KEYSTONE / T-25-core / T-30) feeding T-4→T-9→…→T-15, with an explicit line below: T-29 (C++ ABI) = LANDED (#3267) — NOT a keystone; residual #3277 in-flight. The diagram now matches §3's keystone table and the §1 folded clarifications — single coherent wall-chart.

No "pre-T-29-removal" disclaimer needed; the graphic itself is corrected.

Operator ruled 2026-05-18: substrate-native (B2). registry.dag splits to its own .dag PR (lands now); the ~467-LOC tools/ Rust crate dropped entirely, B1 also rejected — no interim out-of-substrate enforcement shell (Python OR Rust), same thesis ruling as the de-prose-py kill. Whole-corpus gate re-scoped to the v2 filesystem-walk substrate primitive = the T-21/T-24 corpus-drive capability (PREFIX = first consumer). Operator-accepted: CI lens gate lands when that lands.

(1) #3240 is a CLOSED/SUPERSEDED tracker, NOT ratifiable — the keystone artifact is a not-yet-drafted modeling-discipline.md fold PR that still-hawk-102 owns drafting; §7 #3a → "authorize draft", §3 rewritten. (2) "one decision" overstated → "2-3 distinct operator items"; A-vs-B=B stated as IMPLIED by the keystone-fold, not equivalent. (3) §5 two-owner lens seam fixed: Fresh Compiler-Pipeline lens scope GATED on fierce-cat-31 fan-out closeout (one lens owner; no P2 parallel-authority drift). (4) §7 #2 no-revert-of-862bbde6e clause added. Self-consistency pass: fixed 2 stale "ratify #3240" stragglers (§3 blast-radius, §6 r5).

#3313 author flagged two real Wave-2 sequencing gaps: (1) unenumerated std/ prerequisite carriers the L1.x lenses read (canonical_observations, CanonicalConcept, 3 Exemption registries) — T-25-core-class, no owning T-# yet (P10-shape gap); (2) three derived lens-stages (match_arm_shape, closed_vocab_scan, concept_home) = Compiler-Pipeline+Lens lane, NOT Dissolution. Added §4 Wave-2-prereq block + cross-lane edge (Compiler-Pipeline builds → Dissolution Wave-2 consumes); §5 Dissolution row annotated. Reinforces batch-(d) hold.

still-hawk-102 verify-don't-trust'd its own review #1: the keystone FOLD is ALREADY on main (modeling-discipline.md §581-763). Both prior framings ('ratify #3240' and 'authorize a drafting effort') were wrong. Corrected verified-exact: operator ratifies the verbatim invariant blockquote at modeling-discipline.md ~§594-600 (exists, flagged proposed/#3240-A1); still-hawk then lands it into INVARIANTS.md+ MODELING.md + de-hedges 3 sites — SMALL (~30-60 ln, mechanical, low-risk), ratify-exact-text-today not a drafting effort.

…fication (A) still-hawk-102 third self-correction, verified: #3241 (fold) + #3242 (🟡-legend) BOTH merged; the v4 audit sweep #3240-C1 was gated on #3242 (merged), NOT on the A1 invariant — C1 already in motion independently. Retracted the 'authorizing A1 kicks off the v4 sweep' framing in §3(a)/§7#3a: A1 ⇒ ONLY the small placement PR, maximally low-stakes. (B) sunny-wolf-435 (#3313 author) classification, verified NONE fold under T-25-core: (1a) canonical_observations/CanonicalConcept → NEW T-# 'lens-supporting concept registries'; (1b) 3 Exemption registries → fold into each lens's own task, no T-#; (2) 3 derived lens-stages → NEW shared T-# 'Wave-2-prereq lens-pipeline derivations'.

BLOCKING (inline @ :211) — valid; fixed in 9cd983189. Verified: §2 + TASKS.md make T-16 (omni demo) depend on T-11; §4 had both in the T-10 wave (Wave 4) — consumer same-wave as a fresh input. Confirmed, not stale.

Fix is structural, not a patch: replaced the weak "intra-wave ordering" convention with a topological invariant (a task sits strictly later than every task it depends on; within a wave all tasks are mutually independent — dispatch-safe on its face). Re-sorted accordingly: T-16 → Wave 5 (after T-11 in Wave 4); also pre-emptively moved T-4.8 → Wave 3 (deps T-4.7) and T-17 → Wave 4 (deps T-12 real in Wave 3) — that's the same finding-class as the +1 you have queued, now resolved; T-15 → Wave 6 (terminal, deps T-16). Every consumer is now strictly after its fresh inputs.

codex BLOCKING (vs ed8b3b9, pre-resort) demanded T-18-after-T12/13, T-16-after-T-11, AND 'mirror that gating in §5'. §4 was already fixed by 9cd9831; the residual was §5 not mirroring it — the Compiler- Pipeline 'Gated' cell was a flat 'post-T-4' bag obscuring the wave sequence. Now §5 Compiler-Pipeline + Test/Bootstrap-Infra gated columns explicitly mirror §4 topology (W2 T-9 → … → W5 T-16 → W6 T-15). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

codex BLOCKING (2) @ ed8b3b98) — verified against current head; addressed. The review ran on ed8b3b98 (pre-fix); not dismissing as stale — verified the current head satisfies both demands:

§4 dep-edges — already fixed in 9cd983189 (topological re-sort): T-18 → Wave 4 (after T-12/T-13 real in W3), T-16 → Wave 5 (after T-11 W4), plus the same finding-class T-4.8 → W3 (deps T-4.7) and T-17 → W4 (deps T-12 real), T-15 → W6. The weak intra-wave convention was replaced with a strict topological invariant (a task is in a wave strictly later than every dep; within-wave = mutually independent). Zero consumers remain in the same-or-earlier wave as a fresh input.
"mirror that gating in §5" — this was the real residual (§4 fixed, §5 not yet). Now fixed in 7c5bb7476: the §5 Compiler-Pipeline and Test/Bootstrap-Infra "Gated" columns explicitly mirror the §4 wave topology (W2 T-9 → W3 T-10/T-4.8 → W4 T-11/T-17/T-18 → W5 T-16 → W6 T-15) instead of the prior flat "post-T-4" bag.

Both §4 and §5 are now topologically consistent and dispatch-safe on their face.

codex REQUEST_CHANGES — VALID, verified, fixed in d86a217c1. Verified against origin/main: TASKS.md :64 (### Side branch — {P1-KEYSTONE, T-30, T-29, T-25-core} → T-4 → T-9), :286 (T-4 ... [needs T-3, P1-KEYSTONE, T-29, T-30, T-25-core] ... for the cpp slice — the T-29 C++ ABI), :1035 (T-29 ... a hard prerequisite of T-4's cpp slice) — and #3277 (T-29 residual) is OPEN (only #3267 core merged). You're right: the "T-29 LANDED / not a keystone / removed from the critical branch" reclassification was a real P2/Practice-9 documentation-authority violation — the dispatch graph disagreeing with the source of truth, which could mis-sequence T-4's cpp slice.

Fix: T-29 restored as a TASKS.md-declared keystone-cluster T-4-cpp-slice feeder across every load-bearing locus — §1 graph (4-item cluster = TASKS.md:64 exact set), §2 row, §3 keystone table, §4 wave note, §5 extdeps/T-4, §6 review-status. Accurate status now: core #3267 merged; residual #3277 OPEN; remains a declared feeder per TASKS.md; de-classify ONLY when #3277 lands AND TASKS.md updates — authority = TASKS.md, not this plan. The plan no longer contradicts the source of truth.

…cal L1.x keys Bundles three changes operator-routed via witty-cat-59 as the #3313 stabilization trigger: 1. **L1.11 plausible-fallback** — drop the "return type is not Outcome<_>" carve-out that was a false negative on `fn(...) -> Outcome<T>; None => Produced { value: ... }`. Replaces with a structural FailClosedDiagnostic registry declaring Outcome::Rejected as the registered fail-closed constructor. The lens fires on RHS Ctors that are not registered as fail-closed, covering both the F10 bare-return case AND the Outcome-wrapped fabricated-success case the prior signature missed. or_default-style total-by-design helpers escape via a structural PlausibleFallbackExemption row, same shape as L1.8 WrongHomeExemption and L1.9 VacuousArmExemption — no comment anchors. 2. **L1.12 parallel-authority** — reframe so lexical-name collision is the *trigger* (not the conclusion), with four resolution paths the lens checks against the substrate: (1) same-concept-with-alias (CanonicalConcept row + alias edge) → passes (2) same-concept-without-alias (CanonicalConcept row but no alias) → fires (the original duplicate-authority case) (3) distinct-concepts (ConceptDisambiguation row marks them as legitimately different) → passes (4) silence (no row in either registry) → **fires as unresolved-duplicate** The prior formulation only fired on (2) and missed (4) — the F9 motivating case where Bool was declared in two files with no CanonicalConcept row anywhere. The substrate must take a position on every cross-file lexical collision; silence fails closed. 3. **§5.1 Canonical L1.x acceptance-key names** — new subsection enumerating the stable canonical key names downstream consumers (e.g. coverage.dag's dissolution_l1_* rows) must use. The lens suite is the single authority; downstream key sets are projections. Includes explicit migration notes: - `dissolution_l1_6_emit_template` → retired, no L1.6 key - `dissolution_l1_10_string_escape_hatch` → split into `dissolution_l1_10_a_template_hole` AND `dissolution_l1_10_b_canonical_carrier` This is the #3313-stabilization step in #3322's closeout register (item 7). On land: - warm-koi-304's #3318 (held-at-track-not-finalize) can rebase against the stable §5.1 enumeration - batch-(d) remains held until A1 invariant placement PR lands too Routed via witty-cat-59 (program-coordination); follow-up PR owned by sunny-wolf-435 as #3313 author per #3322 closeout-register row 7.

But §2 :85/:86 declare T-4.5 deps {T-3,T-25-core} and T-4.6 deps {T-25-core,T-26} — neither needs P1-KEYSTONE/T-30/T-29. Wave 1 text now gates only T-4 ×5 on the full ×4; T-4.5/T-4.6 unblock on T-25-core (their sole cluster feeder) + own §2 deps, potentially earlier. §2 table reaffirmed as the dependency authority.

One latent ambiguity remained: §5 extdeps/T-4 gated cell listed "T-4.5–4.8" right after "T-4 (post the full feeder set)", readable as T-4.5–4.8 being full-×4-gated. Hardened it to state T-4.5–4.8 follow their own §2 deps (not the full ×4) + §2 is the sole dependency authority — closing the class that successive reviews kept finding one instance of, rather than waiting for the next gap-by-gap flag.

Root cause is hardcoded internal line anchors that re-stale on every edit. Per openai-pro's own "remove the numeric suffix" option, converted ALL internal self-anchors to name-based refs: §5 ":81" dropped; Wave 1 "§2 :85/:86" → "per the §2 T-4.5/T-4.6 row". External src/v4/TASKS.md:NN anchors untouched (different stable file). Permanently closes the brittle-self-anchor sub-class rather than chasing the number each pass.

…cal L1.x keys (#3334) * design-dissolution-lens: propose L1.7–L1.12 from 2026-05-18 ingest Adds six proposed Layer-1 lenses derived from the 2026-05-18 review ingest against `main@e7b8a8d` (corroborated against worktree HEAD). Each section follows the existing L1.x format (signature / decidability / verdict / escape / kills) and includes concrete code-level match cases + clean-shape examples, so the structural signature is reviewable without chasing repo paths. - L1.7 Off-substrate-fact — prose-asserted facts (F3 lattice, F4 width, F11 opacity). Generalizes the standing "machine-readable inhabitance" ruling. - L1.8 Wrong-home — orphan operations (F5 `nat_compare` in float.dag). Mechanizes MODELING M9. - L1.9 Vacuous-arm — exhaustive-but-empty match (F1 `ComputationNode { behavior: _ } => true`). - L1.10 String-escape-hatch — typed-model bypass via String (F6 `ShellCommand { command: String }` vs typed `process.Command`). Generalizes L1.6. - L1.11 Plausible-fallback — fabricated-sibling fallthrough (F10 `DELETE None => CreateEffect`). - L1.12 Parallel-authority — unmarked duplicate concept homes (F9 `dsl/std` vs `src/v4/std`; D2-resolver provisional + planned-absent). Each carries `Status: proposed` in the section header. Slipped-by ledger (§8) gains corresponding rows pinned to current main file locations so the evidence is grep-anchored per §3 methodology.

The lens's case is sharper, not weaker, once the existing tags are visible: they classify the finding shape (dissolution status, scanner anchor) but neither *designates authority* between the two parallel declarations.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * L1.7 / L1.8 / L1.12: tighten hard-gate semantics per codex review Addresses three BLOCKING findings on the L1.7–L1.12 proposal: L1.7 — width discharge must be recursive. The previous signature/clean shape allowed a `Word64 { bytes: List<Byte> where len(_) == 8 }` that bottomed out at an unconstrained `Byte`, so an arbitrary-bit-count `Byte` still inhabited a "well-formed" `Word64`. Signature now requires a recursively-discharged refinement chain down to a fixed-cardinality leaf or primitive bit; clean-shape example shows the full Word64 → Byte → Bit chain and structurally distinct Float32/Float64 exponent/significand widths instead of a shared `FloatBody`. L1.8 — primary-concept selector replaces the argument-files heuristic. Previous signature ("every argument's type lives in file X") missed witness-target homing (a `meet` field of `Lattice<T>` belongs with T, not with whichever file declared its argument types). New four-rule structural cascade in priority order: (1) declared witness target → algebra's type parameter is the home; (2) same-type closure (`fn(T,T)→T` etc.) → T is the home; (3) upstream argument+return convergence on file X → X is the home; (4) no single owner → cross-cutting, lens does not fire. L1.12 — escape valve must be structural, not prose. The previous "// Authority: canonical | historical" comment markers were prose- as-authority — exactly the shape L1.7 exists to kill. The lens is now self-consistent: only structural shapes discharge it — alias/import identity from historical to canonical, a `data ... : HistoricalDeclaration` row in a retirement ledger read as data, or deletion+migration in the same change. Comment markers explicitly do not satisfy the escape, by construction. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.9 / L1.10 / L1.12: remove naming heuristics; substrate-declared facts only Addresses three BLOCKING findings from codex review on cfbc247: L1.9 — replace function-name suffix vocabulary with intra-match asymmetry. The previous signature gated on `*_well_formed` / `*_valid` suffixes — naming as a structural fact, which violates P1 ("heuristics are never structurally necessary"). New signature is purely structural: a single match where ≥1 arm has a trivial-literal RHS AND ≥1 sibling arm does non-trivial structural work. The discipline-role is inferred from the fact that the author already wrote real work for some variants, which makes the trivial siblings a vacuum. The F1 node_locally_well_formed case still fires (TypeNode arm calls edges_conform, ComputationNode arm returns true). L1.10 — replace hardcoded `command`→Command / `path`→Path / `url`→Url field-name table with a substrate-declared canonical-carrier registry. A typed carrier declares `data X: CanonicalCarrier<X> = { supersedes_string: { in_role: <role-tag> } }`; the lens reads the registry. Adding a new typed carrier is now a `data` row in `extdeps/`, not an edit to the lens definition. The lens carries no domain names. L1.12 — split planned-absent-import out of the duplicate-authority lens. They are different failure shapes: duplicate `type T` in two files is a duplicate-authority finding; a dangling import path is an unresolved-reference / fail-closed P3 finding. Collapsing them under one verdict reports the wrong root cause. L1.12 narrows to duplicate-declaration; planned-absent moves to an L0.8-extended row in the slipped-by ledger. The D2-resolver concrete-match block is retitled as a cross-reference note explaining why it does *not* collapse into L1.12. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * L1.10 / L1.12: close opt-in bypass, broaden type-decl signature codex review on 3fb3e4d raised two valid findings: L1.10 — the role-tag refinement created an opt-in opportunity for authors to bypass the typed-carrier rule by omitting the tag. The escape "no role-tag refinement, passes" was convention-level enforcement, not API-level. New signature drops the role-tag mechanism entirely. The CanonicalCarrier registry declares a `supersedes_string_at_field_named` set (substrate data); the lens fires on any String field whose name appears in any in-scope registry entry, unconditionally. The author cannot bypass by omitting an annotation because there is no annotation — the trigger is the field name they chose plus the registry-declared coverage. Legitimate raw-string exemptions move to structural Exemption rows in the same registry, read as data. L1.12 — the prior signature said "type T = ..." literally, which only matches the alias/sum form. The slipped-by ledger row claims coverage of duplicate machine-word homes, but `type Word64 { bytes: List<Byte> }` is record form and would have escaped the literal signature. Broadened to "any `type T` declaration form" — sum/alias, record, unit, generic — with explicit enumeration of the covered forms so the signature unambiguously matches the cases in the section's own examples and ledger. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * L1.1–L1.6: add Concrete match + Clean shape code examples The original L1.1–L1.6 sections describe each lens by signature / decidability / verdict / escape / kills, but did not show what the matching code or the discharging code actually look like. Adds the same "Concrete match" + "Clean shape" example blocks the proposed L1.7–L1.12 sections use, so each lens is concretely readable without chasing the referenced PRs. - L1.1: basic discriminant shape (`nat_is_zero`) + the laundered constant-algebra fold (`free_monoid_is_empty`-via-fold). - L1.2: (a) struct-of-functions (`ListMap<A,B>` wrapper) and (b) N near-identical single-field structs (`{ spelling: String }` ×N). - L1.3: declared-but-never-inhabited type (`ParseError` with no constructor, no `data`, no alias, no field). - L1.4: `Outcome<T>` clone (`NormalizeChildrenResult`), with the three-variant `Cached | Produced | Rejected` shape as the escape. - L1.5: clean recursion mirroring data shape (`ci_member` over List) and the short-circuit `match acc { Rejected => propagate; Ok => continue }` ladder (resolve/normalize walkers). - L1.6: type-construction template tables (`list_template: "Vec<{0}>"`) vs. structural target-type modeling. No signature, verdict, or escape semantics changed; this commit only adds illustrative code blocks. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * A0 umbrella + cross-cutting themes + L1.6→L1.10 merge Implements the consolidation feedback as a middle path: tightens the conceptual scaffolding without dismantling the lens catalog. - §1: introduces A0 ("every semantic fact must have exactly one structural witness") as the umbrella invariant, with A1 retained underneath as the operation-specific specialization. Explicitly framed as operationalizing modeling-discipline.md Practice 10, not as a parallel rulebook, to avoid the L1.12-class parallel-authority hazard of duplicating Practice 10's principles here. - §5.0 (new): adds the three-levels framing (Invariant / Theme / Lens), the lens → theme(s) catalog (derive / witness / canonical-home / fail-closed), and the explicit disclaimer "themes are explanatory tags only — they do not define CI gates, test-corpus boundaries, or implementation passes; the mechanically enforced unit remains the L1.x lens signature." Per the §3 methodology, each lens's signature must be the smallest structural pattern that catches its finding's class with zero false positives, so theme-sharing alone does not collapse machinery. - L1.6 → L1.10 merge: the only mechanical merge in this rev, because the prior doc already stated that L1.10 generalizes L1.6. L1.10 is renamed "Textual-bypass lens" with two sub-signatures: L1.10.a TemplateHole — registry-free, catches `{0}`/`{1}` positional-placeholder string literals used as emitters L1.10.b CanonicalCarrier — substrate-declared registry, catches String fields whose name appears in a CanonicalCarrier coverage set L1.6 section becomes a one-paragraph pointer to L1.10.a, preserving anchor compatibility. The slipped-by ledger's F6 row is repointed to L1.10.b and a new F8 row is added for L1.10.a. L1.2/L1.3/L1.4, L1.8/L1.12, and L1.9/L1.11 are intentionally not merged — their detection machines are mechanically distinct (different signatures, decidability arguments, escape valves) and the operator TDD-pairs directive requires distinct test corpora per lens. They share themes in the §5.0 catalog without sharing implementation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * A0 tightening: witness-path / lens-family / Practice-10 ratification Five sharpening edits from operator review of the A0/themes pass: 1. A0 rephrased: "exactly one structural witness" → "exactly one canonical structural witness *path*". Alias / re-export edges, retirement-ledger rows, and derived operations reading the same witness all point at one authority; they are the path, not a multiplicity that violates A0. 2. §2 "one substrate gap" claim updated. The original sentence was true for the L1.1/L1.5 seed findings but too narrow for A0's broader territory. Now distinguishes the seed gap (no derived discriminant/catamorphism → workers hand-roll them) from the general gap (missing witness table / authority map / refinement edge / diagnostic carrier → workers encode locally in prose / names / strings / duplicate homes / plausible defaults). 3. L1.10 explicitly renamed "Textual-bypass lens family" with an "Exception to §5.0" note: L1.10.a TemplateHole and L1.10.b CanonicalCarrier are the mechanical units, sharing a finding family and reporting label but keeping separate signatures, decidability arguments, escapes, and test corpora. Resolves the tension between §5.0 ("the mechanically enforced unit is the L1.x signature") and L1.10's two-detector structure. 4. L1.6 stub retitled "Deprecated alias — see L1.10.a `TemplateHole`" so old test names and slipped-by references remain traceable. 5. §8 trailing prose fixed: "all four are burn-down substrate PRs" was true when the ledger had four rows; now it has the four seed rows plus the ingest extension. Reframed as "Pattern from the seed PR rows" with an explicit note that the ingest rows extend the ledger to A0's broader territory. 6. A0/A1 ratification sentence made authority-chain explicit: "Once ratified into Practice 10, A0/A1 become citable hard rules; this doc remains the enforcement mechanism." Avoids the rulebook-ish phrasing that suggested A0/A1 were independently citable. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * §10 Dependency model — lenses are pipeline stages, not infrastructure Adds a new §10 (renumbering audit to §11) answering the "how does this run / is it parallelizable / how much work" questions operationally. The core framing: there is no "lens framework" separate from the compiler pipeline. Lenses are .dag stages that declare consumes: edges against the existing parse/resolve/infer producers, and the compiler's stage-ordering schedules them automatically. - §10.1: shared-indices taxonomy — maps each shared structural fact (AST, symbol resolution, variant lists, inhabitance edges, witness registries, refinement clauses, import graph, fail-closed return- type carriers) to the existing pipeline stage that produces it and the lenses that consume it. Most of what lenses need is already computed; lenses just query. - §10.2: three small derived stages cover what the existing pipeline doesn't yet expose — match_arm_shape (reusable by L1.1, L1.9, L1.11, L0.7, L0.13), closed_vocab_scan (L1.7), concept_home (L1.8). Each is a single deterministic fold; reusable across multiple lenses by design. - §10.3: a lens is just another .dag stage with declared dependencies. Adding a lens = land a stage; the existing compiler stage-ordering handles scheduling. No new framework. - §10.4: per-file and per-lens parallelism fall out of the dependency graph automatically; affected_set integration scales CI cost with PR size, not corpus size. - §10.5: summary of operational properties — one dependency model across pipeline + lenses, lens addition = stage land, index addition = small derivation stage shared by all lenses that need it, self-application clean (the compiler enforces the discipline it follows). This is the L1.12-class self-consistency check: a separate "lens framework" with its own dependency model would itself be parallel authority, which the lens suite exists to kill. The dependency-model section makes explicit that the lens framework reuses the pipeline's existing modeling — one dependency system for everything. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * design-dissolution-lens: stabilize #3313 — L1.11/L1.12 fixes + canonical L1.x keys Bundles three changes operator-routed via witty-cat-59 as the #3313 stabilization trigger: 1. **L1.11 plausible-fallback** — drop the "return type is not Outcome<_>" carve-out that was a false negative on `fn(...) -> Outcome<T>; None => Produced { value: ... }`. Replaces with a structural FailClosedDiagnostic registry declaring Outcome::Rejected as the registered fail-closed constructor. The lens fires on RHS Ctors that are not registered as fail-closed, covering both the F10 bare-return case AND the Outcome-wrapped fabricated-success case the prior signature missed. or_default-style total-by-design helpers escape via a structural PlausibleFallbackExemption row, same shape as L1.8 WrongHomeExemption and L1.9 VacuousArmExemption — no comment anchors. 2. **L1.12 parallel-authority** — reframe so lexical-name collision is the *trigger* (not the conclusion), with four resolution paths the lens checks against the substrate: (1) same-concept-with-alias (CanonicalConcept row + alias edge) → passes (2) same-concept-without-alias (CanonicalConcept row but no alias) → fires (the original duplicate-authority case) (3) distinct-concepts (ConceptDisambiguation row marks them as legitimately different) → passes (4) silence (no row in either registry) → **fires as unresolved-duplicate** The prior formulation only fired on (2) and missed (4) — the F9 motivating case where Bool was declared in two files with no CanonicalConcept row anywhere. The substrate must take a position on every cross-file lexical collision; silence fails closed. 3. **§5.1 Canonical L1.x acceptance-key names** — new subsection enumerating the stable canonical key names downstream consumers (e.g. coverage.dag's dissolution_l1_* rows) must use. The lens suite is the single authority; downstream key sets are projections. Includes explicit migration notes: - `dissolution_l1_6_emit_template` → retired, no L1.6 key - `dissolution_l1_10_string_escape_hatch` → split into `dissolution_l1_10_a_template_hole` AND `dissolution_l1_10_b_canonical_carrier` This is the #3313-stabilization step in #3322's closeout register (item 7). On land: - warm-koi-304's #3318 (held-at-track-not-finalize) can rebase against the stable §5.1 enumeration - batch-(d) remains held until A1 invariant placement PR lands too Routed via witty-cat-59 (program-coordination); follow-up PR owned by sunny-wolf-435 as #3313 author per #3322 closeout-register row 7. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.12 wording: "three resolutions" → "four outcomes (three passing + silence)" cursor/composer-2 review noted editorial inconsistency: the text said "exactly one of three resolutions" but the list enumerated 1-4 with silence as case (4). Corrected to "one of four outcomes — three passing resolutions plus a fail-closed silence case" so the prose matches the structural enumeration that follows. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.12: close the decision table — five outcomes, all in-table Reviewer (briansrls 2026-05-18T23:26Z) flagged that the prior wording said "three passing resolutions" but the enumerated 1-4 list had only TWO passing (alias, ConceptDisambiguation) and TWO firing (same-concept-without-alias, silence). The HistoricalDeclaration retirement-ledger and deletion/migration paths from the Escape section were "outside the stated decision table" — a P2 decidable-single- authority violation. Fix: restructure the enumeration to cover ALL mechanically-distinct outcomes inline, so the decision table is closed: (1) Same-concept-with-alias → passes (2) Same-concept-with-retirement-record → passes (new: was in Escape) (3) Distinct concepts (ConceptDisambiguation) → passes (4) Same-concept-without-alias-or-retirement → fires (original duplicate-authority case) (5) Silence → fires (unresolved-duplicate) Three passing + two firing = the arithmetic now matches. Deletion / migration is explicitly noted as "not a fifth resolution" — it removes the trigger condition entirely (no lexical collision), so the lens never engages, which is mechanically distinct from a resolution. The Escape section is collapsed to a pointer at outcomes (1)/(2)/(3) to avoid duplicating the decision-table content. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.12 Decidable bullet: include HistoricalDeclaration registry Closes the residual gap on the wrap BLOCKING review: outcome (2) "Same-concept-with-retirement-record" consults a HistoricalDeclaration registry row, but the prior Decidable bullet listed only CanonicalConcept + structural-alias + ConceptDisambiguation. Now every registry the 5-outcome decision table consults is named in the decidability statement explicitly. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * L1.11 Verdict: per-case fix guidance (bare-return vs Outcome-wrapped) cursor/composer-2 review caught a contradictory-guidance bug: the new L1.11 bullets explicitly include the Outcome-wrapped case (fn(...) -> Outcome<T>; None => Produced { value: ... }) as firing, but the Verdict still said "lift the return type to Outcome<T> and return Rejected" — which doesn't address the case that's already Outcome-wrapped. Split the fix into two case-specific guidances: - Bare-return case: lift return type to Outcome<T>, return Rejected. - Outcome-wrapped case: replace Produced ctor with Rejected { diagnostic: DerivationUnknown } on the missing-info arm. Same underlying fix shape (escalate missing info through the registered fail-closed-diagnostic variant) — just two distinct starting points depending on which form of fabricated-success the lens caught. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.12: restore concept-level detection via two-trigger union (lexical OR CanonicalConcept co-membership) codex review (REQUEST_CHANGES) caught a real semantic weakening in the prior "lexical collision is the trigger" rewrite: two parallel homes for ONE concept with DIFFERENT names would slip past the lens entirely, contradicting P2 / Practice 5's concept-level single-authority demand. Fix: restore concept-level detection by adding Trigger B (concept- graph) alongside the existing Trigger A (lexical). The lens fires on parallel authority detectable in EITHER way: - **Trigger A (lexical):** cross-file `type T` declarations sharing a simple name. (Existing; catches the F9 motivating case.) - **Trigger B (concept-graph):** two `type T1` / `type T2` declarations in different files that are co-members of a `CanonicalConcept` row, regardless of whether their lexical names match. (NEW; catches the same-concept-different-name case the prior rewrite missed.) Either trigger enters the same 5-outcome resolution table. Per-outcome under Trigger B: - (1) alias / (2) retirement-record / (4) no-resolution apply cleanly to both triggers - (3) ConceptDisambiguation under Trigger B would CONTRADICT the CanonicalConcept co-membership row — registry-inconsistency, caught by L0-class checks, not L1.12 - (5) silence is NOT reachable under Trigger B (the trigger IS a registry row's presence); only reachable under Trigger A Also added an explicit Decidability Boundary note: the lens cannot catch the case where two homes use different names AND no CanonicalConcept row registers them as the same concept. That's a P2 violation but mechanically undetectable from parsed substrate alone — closing it requires either operator judgment or a future structural-similarity-fold primitive. Per §3 methodology, lens signatures catch their class with zero false positives; Trigger B's CanonicalConcept-driven gate is the structural surface decidable today.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.9 / L1.10 / L1.12: remove naming heuristics; substrate-declared facts only Addresses three BLOCKING findings from codex review on cfbc247: L1.9 — replace function-name suffix vocabulary with intra-match asymmetry. The previous signature gated on `*_well_formed` / `*_valid` suffixes — naming as a structural fact, which violates P1 ("heuristics are never structurally necessary"). New signature is purely structural: a single match where ≥1 arm has a trivial-literal RHS AND ≥1 sibling arm does non-trivial structural work. The discipline-role is inferred from the fact that the author already wrote real work for some variants, which makes the trivial siblings a vacuum. The F1 node_locally_well_formed case still fires (TypeNode arm calls edges_conform, ComputationNode arm returns true). L1.10 — replace hardcoded `command`→Command / `path`→Path / `url`→Url field-name table with a substrate-declared canonical-carrier registry. A typed carrier declares `data X: CanonicalCarrier<X> = { supersedes_string: { in_role: <role-tag> } }`; the lens reads the registry. Adding a new typed carrier is now a `data` row in `extdeps/`, not an edit to the lens definition. The lens carries no domain names. L1.12 — split planned-absent-import out of the duplicate-authority lens. They are different failure shapes: duplicate `type T` in two files is a duplicate-authority finding; a dangling import path is an unresolved-reference / fail-closed P3 finding. Collapsing them under one verdict reports the wrong root cause. L1.12 narrows to duplicate-declaration; planned-absent moves to an L0.8-extended row in the slipped-by ledger. The D2-resolver concrete-match block is retitled as a cross-reference note explaining why it does *not* collapse into L1.12. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * L1.10 / L1.12: close opt-in bypass, broaden type-decl signature codex review on 3fb3e4d raised two valid findings: L1.10 — the role-tag refinement created an opt-in opportunity for authors to bypass the typed-carrier rule by omitting the tag. The escape "no role-tag refinement, passes" was convention-level enforcement, not API-level. New signature drops the role-tag mechanism entirely. The CanonicalCarrier registry declares a `supersedes_string_at_field_named` set (substrate data); the lens fires on any String field whose name appears in any in-scope registry entry, unconditionally. The author cannot bypass by omitting an annotation because there is no annotation — the trigger is the field name they chose plus the registry-declared coverage. Legitimate raw-string exemptions move to structural Exemption rows in the same registry, read as data. L1.12 — the prior signature said "type T = ..." literally, which only matches the alias/sum form. The slipped-by ledger row claims coverage of duplicate machine-word homes, but `type Word64 { bytes: List<Byte> }` is record form and would have escaped the literal signature. Broadened to "any `type T` declaration form" — sum/alias, record, unit, generic — with explicit enumeration of the covered forms so the signature unambiguously matches the cases in the section's own examples and ledger.

Adds the same "Concrete match" + "Clean shape" example blocks the proposed L1.7–L1.12 sections use, so each lens is concretely readable without chasing the referenced PRs. - L1.1: basic discriminant shape (`nat_is_zero`) + the laundered constant-algebra fold (`free_monoid_is_empty`-via-fold). - L1.2: (a) struct-of-functions (`ListMap<A,B>` wrapper) and (b) N near-identical single-field structs (`{ spelling: String }` ×N). - L1.3: declared-but-never-inhabited type (`ParseError` with no constructor, no `data`, no alias, no field). - L1.4: `Outcome<T>` clone (`NormalizeChildrenResult`), with the three-variant `Cached | Produced | Rejected` shape as the escape. - L1.5: clean recursion mirroring data shape (`ci_member` over List) and the short-circuit `match acc { Rejected => propagate; Ok => continue }` ladder (resolve/normalize walkers). - L1.6: type-construction template tables (`list_template: "Vec<{0}>"`) vs. structural target-type modeling. No signature, verdict, or escape semantics changed; this commit only adds illustrative code blocks. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * A0 umbrella + cross-cutting themes + L1.6→L1.10 merge Implements the consolidation feedback as a middle path: tightens the conceptual scaffolding without dismantling the lens catalog. - §1: introduces A0 ("every semantic fact must have exactly one structural witness") as the umbrella invariant, with A1 retained underneath as the operation-specific specialization. Explicitly framed as operationalizing modeling-discipline.md Practice 10, not as a parallel rulebook, to avoid the L1.12-class parallel-authority hazard of duplicating Practice 10's principles here. - §5.0 (new): adds the three-levels framing (Invariant / Theme / Lens), the lens → theme(s) catalog (derive / witness / canonical-home / fail-closed), and the explicit disclaimer "themes are explanatory tags only — they do not define CI gates, test-corpus boundaries, or implementation passes; the mechanically enforced unit remains the L1.x lens signature." Per the §3 methodology, each lens's signature must be the smallest structural pattern that catches its finding's class with zero false positives, so theme-sharing alone does not collapse machinery. - L1.6 → L1.10 merge: the only mechanical merge in this rev, because the prior doc already stated that L1.10 generalizes L1.6. L1.10 is renamed "Textual-bypass lens" with two sub-signatures: L1.10.a TemplateHole — registry-free, catches `{0}`/`{1}` positional-placeholder string literals used as emitters L1.10.b CanonicalCarrier — substrate-declared registry, catches String fields whose name appears in a CanonicalCarrier coverage set L1.6 section becomes a one-paragraph pointer to L1.10.a, preserving anchor compatibility. The slipped-by ledger's F6 row is repointed to L1.10.b and a new F8 row is added for L1.10.a. L1.2/L1.3/L1.4, L1.8/L1.12, and L1.9/L1.11 are intentionally not merged — their detection machines are mechanically distinct (different signatures, decidability arguments, escape valves) and the operator TDD-pairs directive requires distinct test corpora per lens. They share themes in the §5.0 catalog without sharing implementation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * A0 tightening: witness-path / lens-family / Practice-10 ratification Five sharpening edits from operator review of the A0/themes pass: 1. A0 rephrased: "exactly one structural witness" → "exactly one canonical structural witness *path*". Alias / re-export edges, retirement-ledger rows, and derived operations reading the same witness all point at one authority; they are the path, not a multiplicity that violates A0. 2. §2 "one substrate gap" claim updated. The original sentence was true for the L1.1/L1.5 seed findings but too narrow for A0's broader territory. Now distinguishes the seed gap (no derived discriminant/catamorphism → workers hand-roll them) from the general gap (missing witness table / authority map / refinement edge / diagnostic carrier → workers encode locally in prose / names / strings / duplicate homes / plausible defaults). 3. L1.10 explicitly renamed "Textual-bypass lens family" with an "Exception to §5.0" note: L1.10.a TemplateHole and L1.10.b CanonicalCarrier are the mechanical units, sharing a finding family and reporting label but keeping separate signatures, decidability arguments, escapes, and test corpora. Resolves the tension between §5.0 ("the mechanically enforced unit is the L1.x signature") and L1.10's two-detector structure. 4. L1.6 stub retitled "Deprecated alias — see L1.10.a `TemplateHole`" so old test names and slipped-by references remain traceable. 5. §8 trailing prose fixed: "all four are burn-down substrate PRs" was true when the ledger had four rows; now it has the four seed rows plus the ingest extension. Reframed as "Pattern from the seed PR rows" with an explicit note that the ingest rows extend the ledger to A0's broader territory. 6. A0/A1 ratification sentence made authority-chain explicit: "Once ratified into Practice 10, A0/A1 become citable hard rules; this doc remains the enforcement mechanism." Avoids the rulebook-ish phrasing that suggested A0/A1 were independently citable. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * §10 Dependency model — lenses are pipeline stages, not infrastructure Adds a new §10 (renumbering audit to §11) answering the "how does this run / is it parallelizable / how much work" questions operationally. The core framing: there is no "lens framework" separate from the compiler pipeline. Lenses are .dag stages that declare consumes: edges against the existing parse/resolve/infer producers, and the compiler's stage-ordering schedules them automatically. - §10.1: shared-indices taxonomy — maps each shared structural fact (AST, symbol resolution, variant lists, inhabitance edges, witness registries, refinement clauses, import graph, fail-closed return- type carriers) to the existing pipeline stage that produces it and the lenses that consume it. Most of what lenses need is already computed; lenses just query. - §10.2: three small derived stages cover what the existing pipeline doesn't yet expose — match_arm_shape (reusable by L1.1, L1.9, L1.11, L0.7, L0.13), closed_vocab_scan (L1.7), concept_home (L1.8). Each is a single deterministic fold; reusable across multiple lenses by design. - §10.3: a lens is just another .dag stage with declared dependencies. Adding a lens = land a stage; the existing compiler stage-ordering handles scheduling. No new framework. - §10.4: per-file and per-lens parallelism fall out of the dependency graph automatically; affected_set integration scales CI cost with PR size, not corpus size. - §10.5: summary of operational properties — one dependency model across pipeline + lenses, lens addition = stage land, index addition = small derivation stage shared by all lenses that need it, self-application clean (the compiler enforces the discipline it follows). This is the L1.12-class self-consistency check: a separate "lens framework" with its own dependency model would itself be parallel authority, which the lens suite exists to kill. The dependency-model section makes explicit that the lens framework reuses the pipeline's existing modeling — one dependency system for everything. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * design-dissolution-lens: stabilize #3313 — L1.11/L1.12 fixes + canonical L1.x keys Bundles three changes operator-routed via witty-cat-59 as the #3313 stabilization trigger: 1. **L1.11 plausible-fallback** — drop the "return type is not Outcome<_>" carve-out that was a false negative on `fn(...) -> Outcome<T>; None => Produced { value: ... }`. Replaces with a structural FailClosedDiagnostic registry declaring Outcome::Rejected as the registered fail-closed constructor. The lens fires on RHS Ctors that are not registered as fail-closed, covering both the F10 bare-return case AND the Outcome-wrapped fabricated-success case the prior signature missed. or_default-style total-by-design helpers escape via a structural PlausibleFallbackExemption row, same shape as L1.8 WrongHomeExemption and L1.9 VacuousArmExemption — no comment anchors. 2. **L1.12 parallel-authority** — reframe so lexical-name collision is the *trigger* (not the conclusion), with four resolution paths the lens checks against the substrate: (1) same-concept-with-alias (CanonicalConcept row + alias edge) → passes (2) same-concept-without-alias (CanonicalConcept row but no alias) → fires (the original duplicate-authority case) (3) distinct-concepts (ConceptDisambiguation row marks them as legitimately different) → passes (4) silence (no row in either registry) → **fires as unresolved-duplicate** The prior formulation only fired on (2) and missed (4) — the F9 motivating case where Bool was declared in two files with no CanonicalConcept row anywhere. The substrate must take a position on every cross-file lexical collision; silence fails closed. 3. **§5.1 Canonical L1.x acceptance-key names** — new subsection enumerating the stable canonical key names downstream consumers (e.g. coverage.dag's dissolution_l1_* rows) must use. The lens suite is the single authority; downstream key sets are projections. Includes explicit migration notes: - `dissolution_l1_6_emit_template` → retired, no L1.6 key - `dissolution_l1_10_string_escape_hatch` → split into `dissolution_l1_10_a_template_hole` AND `dissolution_l1_10_b_canonical_carrier` This is the #3313-stabilization step in #3322's closeout register (item 7). On land: - warm-koi-304's #3318 (held-at-track-not-finalize) can rebase against the stable §5.1 enumeration - batch-(d) remains held until A1 invariant placement PR lands too Routed via witty-cat-59 (program-coordination); follow-up PR owned by sunny-wolf-435 as #3313 author per #3322 closeout-register row 7. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.12 wording: "three resolutions" → "four outcomes (three passing + silence)" cursor/composer-2 review noted editorial inconsistency: the text said "exactly one of three resolutions" but the list enumerated 1-4 with silence as case (4). Corrected to "one of four outcomes — three passing resolutions plus a fail-closed silence case" so the prose matches the structural enumeration that follows. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.12: close the decision table — five outcomes, all in-table Reviewer (briansrls 2026-05-18T23:26Z) flagged that the prior wording said "three passing resolutions" but the enumerated 1-4 list had only TWO passing (alias, ConceptDisambiguation) and TWO firing (same-concept-without-alias, silence). The HistoricalDeclaration retirement-ledger and deletion/migration paths from the Escape section were "outside the stated decision table" — a P2 decidable-single- authority violation. Fix: restructure the enumeration to cover ALL mechanically-distinct outcomes inline, so the decision table is closed: (1) Same-concept-with-alias → passes (2) Same-concept-with-retirement-record → passes (new: was in Escape) (3) Distinct concepts (ConceptDisambiguation) → passes (4) Same-concept-without-alias-or-retirement → fires (original duplicate-authority case) (5) Silence → fires (unresolved-duplicate) Three passing + two firing = the arithmetic now matches. Deletion / migration is explicitly noted as "not a fifth resolution" — it removes the trigger condition entirely (no lexical collision), so the lens never engages, which is mechanically distinct from a resolution. The Escape section is collapsed to a pointer at outcomes (1)/(2)/(3) to avoid duplicating the decision-table content. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.12 Decidable bullet: include HistoricalDeclaration registry Closes the residual gap on the wrap BLOCKING review: outcome (2) "Same-concept-with-retirement-record" consults a HistoricalDeclaration registry row, but the prior Decidable bullet listed only CanonicalConcept + structural-alias + ConceptDisambiguation. Now every registry the 5-outcome decision table consults is named in the decidability statement explicitly. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * L1.11 Verdict: per-case fix guidance (bare-return vs Outcome-wrapped) cursor/composer-2 review caught a contradictory-guidance bug: the new L1.11 bullets explicitly include the Outcome-wrapped case (fn(...) -> Outcome<T>; None => Produced { value: ... }) as firing, but the Verdict still said "lift the return type to Outcome<T> and return Rejected" — which doesn't address the case that's already Outcome-wrapped. Split the fix into two case-specific guidances: - Bare-return case: lift return type to Outcome<T>, return Rejected. - Outcome-wrapped case: replace Produced ctor with Rejected { diagnostic: DerivationUnknown } on the missing-info arm. Same underlying fix shape (escalate missing info through the registered fail-closed-diagnostic variant) — just two distinct starting points depending on which form of fabricated-success the lens caught. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * L1.12: restore concept-level detection via two-trigger union (lexical OR CanonicalConcept co-membership) codex review (REQUEST_CHANGES) caught a real semantic weakening in the prior "lexical collision is the trigger" rewrite: two parallel homes for ONE concept with DIFFERENT names would slip past the lens entirely, contradicting P2 / Practice 5's concept-level single-authority demand. Fix: restore concept-level detection by adding Trigger B (concept- graph) alongside the existing Trigger A (lexical). The lens fires on parallel authority detectable in EITHER way: - **Trigger A (lexical):** cross-file `type T` declarations sharing a simple name. (Existing; catches the F9 motivating case.) - **Trigger B (concept-graph):** two `type T1` / `type T2` declarations in different files that are co-members of a `CanonicalConcept` row, regardless of whether their lexical names match. (NEW; catches the same-concept-different-name case the prior rewrite missed.) Either trigger enters the same 5-outcome resolution table. Per-outcome under Trigger B: - (1) alias / (2) retirement-record / (4) no-resolution apply cleanly to both triggers - (3) ConceptDisambiguation under Trigger B would CONTRADICT the CanonicalConcept co-membership row — registry-inconsistency, caught by L0-class checks, not L1.12 - (5) silence is NOT reachable under Trigger B (the trigger IS a registry row's presence); only reachable under Trigger A Also added an explicit Decidability Boundary note: the lens cannot catch the case where two homes use different names AND no CanonicalConcept row registers them as the same concept. That's a P2 violation but mechanically undetectable from parsed substrate alone — closing it requires either operator judgment or a future structural-similarity-fold primitive. Per §3 methodology, lens signatures catch their class with zero false positives; Trigger B's CanonicalConcept-driven gate is the structural surface decidable today. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * docs(design): read/edit pipeline — node-centric agent surface (design spec) Frames the substrate's read/edit surface for arbitrary code at the Node level — not the file level. Files are a delivery / persistence mechanism modeled via extdeps/file_system.dag; the language doesn't couple to them. Reads target Nodes (and scopes within Nodes); writes are structural Edits to Nodes; Node-to-File binding is its own concern, modeled alongside Node, not inside it. Operator-stated motivation (2026-05-19): the mechanical part of shifting bits isn't the hard part — the INTERFACE is. This doc captures the design intent + worked examples + open interface questions, especially for LLM/agent consumers. Doc structure: - §0-1: framing — why node-centric, not file-centric (3 reasons: files decoupled from concepts; edits should be structural; agent reasoning is at concept level) - §2: read interface — apply_lens(lens, scope, mode) per QRY-1 ratification (2026-05-15); no separate query subsystem; lens catalog + composition - §3: write interface — Path/Edit/Diff per #3162 ratification; apply_diff fold semantics (all-or-nothing fail-closed) - §4: read → edit pipeline — six-step closed loop (Read → Diagnose → Propose → Gate → Apply → Re-emit). Files only re-enter at Re-emit; they're a downstream effect of substrate state. - §5: three worked examples — (A) bare-alias refactor to canonical-B (same shape as #3338); (B) rename a concept across the corpus via CanonicalConcept registry cascade; (C) TestClaim breakage diagnosis + fix - §6: six open interface questions — higher-order Edit combinators, composition under overlap, intent-shaped declarations (generalized Track 2), LLM-targeted diagnostic shape, workflow-as-data for the agent loop, structural provenance traces - §7-8: scope clarifications + status Status: design spec; mechanical primitives exist, T-23 realizes them; the six open interface questions are where the substantive interface design work lives. No implementation prescribed. This is operator-requested framing work, not action work. Each open question becomes its own follow-up doc / PR when picked up. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * WIP: PM * design-read-edit-pipeline: fix two P2 / THESIS-narrowing findings from openai-pro RC openai-pro (gpt-5-5-pro) review on f15b2b0 flagged two valid issues: **Finding 1: affected_set as implicit third scope (P2 violation).** §2 said "frontier is itself a scope" and §5/§6 examples passed `affected_set(dag, diff)` as `NodeScope(affected)`, but the ratified SectionRef is two-branch only (DeclarationScope | NodeScope). Treating `Witness<ReExecFrontier>` as a NodeScope-compatible value is an implicit coercion the typed surface doesn't model — violates P2 illegal-states-unrepresentable. Fix: clarify §2 that the frontier is a SET of declaration/node refs the caller folds over by re-applying the lens at each member's existing DeclarationScope/NodeScope. Rewrite all five affected worked-example sites (Examples A + 6.3 + 6.6) to fold over `affected.frontier.for_each(ref => apply_lens(_, ref, Enforce))` instead of passing `NodeScope(affected)`. SectionRef stays two-branch; gating over the affected frontier is composition, not a new scope shape. **Finding 2: workflow/agent_loop.dag conflicts with THESIS narrowing (LOCKED DESIGN DECISIONS).** §7.5 proposed extending self-application to `workflow/agent_loop.dag`, but THESIS retracted meta-process / work-direction modeling on 2026-05-15; self-application is narrowed to gunbc's own build/CI pipeline (workflow/{bootstrap, ci} only). The reviewer correctly noted my open question would reopen exactly the surface THESIS removed. Fix: reframe the open question per the reviewer's "out-of-scope / user-program workflow" option. The agent loop is a USER PROGRAM composing substrate primitives (apply_lens, apply_diff, affected_set, emit) — not an extension of gunbc's workflow/ surface. Renamed §7.5 from "Workflow-as-data for the agent loop" to "Agent-loop composition at the user-program level" and explicitly stated `workflow/agent_loop.dag` is not the right place; THESIS narrowing stands. The substantive open question (what user-program-side carriers ship with gunbc as conveniences vs are user-program-authored) is preserved without reopening the locked surface. §6.6 (CLI-driven concept declaration hero case) cross-reference also updated to call it out as a user-program composing primitives, not gunbc self-application. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * design-read-edit-pipeline: honest accounting of Node→File binding gap openai-pro BLOCKING inline at line 33 (sha c431266) flagged that the doc overclaimed file_system.dag's coverage: it models POSIX file operations (open/read/write/close) but does NOT yet carry a Node→File rendering binding as a first-class substrate fact. The relationship is currently emergent from the emit stage, not stored as queryable substrate data — claiming "file-tying is a structural fact" left the central file-binding authority off-substrate. Fixes: 1. **§1 rewrite (lines 41-44)**: replace the overclaim "the substrate models File explicitly ... so file-tying is a structural fact" with an honest accounting: file_system.dag is POSIX ops only; the Node-to-File relationship is currently emergent from emit, NOT a queryable data row. Design intent is right (file-tying as substrate data so it's queryable and auditable, not implicit in emit behavior), but the primitive doesn't exist yet. Tracked as a §6.8 gap. 2. **§6.8 addition (item 6)**: add Node→File binding registry to the missing-substrate list. Concrete shape: `data <node>_rendered_into: NodeToFileBinding = { node, file, region }`. Closes the "files are a downstream effect of substrate state" framing — that effect becomes a structurally-recorded fact, not just a compile-time side effect. The design intent (node-centric, file-as-effect) survives intact; the honest update is that one of the substrate primitives needed to make it fully structural still has to land. That's the right shape per INVARIANTS P2 (illegal-states-unrepresentable / single authority): don't claim a structural fact that isn't yet stored as queryable data — name the gap as a tracked dependency. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * design-read-edit-pipeline: mirror ratified Edit definition exactly (replacement only) openai-pro BLOCKING inline at line 81 flagged that the doc's description of Edit as "Replace / insert / delete at a position" contradicted the ratified std/node.dag authority, which defines: type Edit { at: Path, replacement: Node } type Diff { edits: List<Edit> } type Path { steps: List<Symbol> } Edit is a SINGLE replacement at a Path — no separate insert / delete variants. The "Replace / insert / delete" prose introduced operations the ratified type doesn't model, violating P2 single-authority. Fix: replace the prose with the exact ratified shape, noting that insertions and deletions are expressed by replacing the parent node with a new parent whose children list includes / excludes the targeted child. This is the natural decomposition under the ratified single-Edit shape and avoids inventing a parallel contract. Same single-authority fix shape as the earlier SectionRef + apply_diff alignments — point at the ratified definition rather than restate with diverged wording. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * design-read-edit-pipeline: mark §5/§6 examples as future-combinator-layer pseudo-code codex BLOCKING review (sha:1dcf5193) wrap raised three findings; two were already addressed in prior commits (c431266 affected_set scope collapse + ab4bcdb Edit shape mismatch). The third is the worked examples using higher-level edit verbs (replace_with, replace, insert, insert_field) that don't map directly to the ratified Edit { at: Path, replacement: Node } shape. Per the reviewer's "either express as replacement-at-path rewrites or mark them as a future combinator layer" binary: chose mark-as-future- combinator-layer because the examples are illustrative intent shapes, not authoritative Edit constructors. Rewriting each into explicit parent-replacement decomposition would make the examples much longer and harder to read for the design intent they're meant to convey. Added a clear pseudo-code disclaimer at the top of §5 ("worked examples") that covers both §5 and §6 examples: - States the verbs (replace_with, replace, insert, insert_field) are future-combinator-layer shorthand, NOT literal .dag - Cites §3 for the ratified Edit { at: Path, replacement: Node } - Explains the decomposition: insertions/field-additions land as parent-replacement (build a new parent node whose children list includes the desired child, single Edit at parent_path) - Points at §6.8 items 1 + 3 (machine-readable Clean shape + DAG-of-edits composition) as the substrate work that builds the combinator layer - "Treat the examples as intent illustrations, not authoritative Edit constructors" This restores single-authority discipline: §3 names the ratified Edit shape, and the examples are explicitly framed as combinator-layer pseudo-code that compresses common intent shapes for readability. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * design-read-edit-pipeline: candidate-state gating + grounded L1.12 transform openai-pro REQUEST_CHANGES on b26f0d8 raised two valid design-level defects, both blocking: **Finding 1 — gate/apply ordering bug** (P3 fail-closed / structure gates emission). The §4 pipeline was: 4. Gate on affected_set (pre-edit graph) 5. Apply diff That gates the PRE-edit state then applies the Diff, letting a Diff introduce post-edit invariant violations that never get enforced before re-emit. Violates THESIS:13-15 + :453-457 "compiler validates every causal link before emitting to targets." Fix: rewrite §4 as a SEVEN-step candidate-state pattern: 1. Read 2. Diagnose 3. Propose Diff 4. Candidate: candidate_dag = apply_diff(dag, Diff) # uncommitted 5. Gate: enforce lenses against the CANDIDATE state 6. Commit: dag := candidate_dag (only if every gate passed) 7. Re-emit Added explicit "Why gate the candidate, not the pre-edit graph" paragraph naming the semantic gap the prior ordering would have created. The "fail-closed promise honest" framing: validation happens against the state that will be emitted, not against a state already known to be valid. Updated worked examples (§5.A, §6.3 catamorphism pipeline, §6.6 CLI pipeline) to use the candidate-state ordering throughout — apply_diff to candidate, gate against candidate, commit if green. **Finding 2 — L1.12 transform with ungrounded canonical-home pick.** §6.4 L1_12_transform called `pick_canonical_home(matched_pair)` in the outcome (5) silence case (no CanonicalConcept row anywhere). That's ungrounded inference — picking which side is canonical when the substrate has no canonical authority declared. INVARIANTS:31-32 says missing facts should be authored, not inferred by shortcuts. Fix: rewrite L1_12_transform to branch on outcome: - **Outcome (4)** same-concept-without-alias-or-retirement: a CanonicalConcept row EXISTS; READ canonical_home from it. Auto(Diff). - **Outcome (5)** silence: no canonical authority declared. NeedsDecision { because: no_canonical_authority, needs: operator_authors_CanonicalConcept_row { candidates: pair } }. Never an inferred pick. Added the general pattern statement: "transforms ground in substrate-declared authority; absence of authority becomes NeedsDecision, never an inferred guess." This is the design rule for every L1.x transform — auto-fix only when the substrate gives you grounded structural facts to fix toward. Both fixes preserve the design direction and tighten it on the fail-closed-and-no-inferred-authority discipline the project thesis demands. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * design-read-edit-pipeline: add hero case (f) — mechanical refactor Operator-articulated hero case (2026-05-19): mechanical refactors — declarative model-A → model-B transitions across the corpus — are "a good use case for more mechanical things (i.e. the only judgement applied is in which command to run, not literally changing each line)." Adds §6.7b as the sixth hero case, between merge-sort synthesis (§6.7) and the missing-substrate enumeration (§6.8). Key positioning: - **Cleanest convolution shape** — judgment at command-selection, zero per-site judgment. Distinguished from the other cases: (a) one lens auto-fix (b) one lens with conditional outcomes (c) per-site conditional cascade (f) declarative target, uniform per-site application - **Substrate guarantees** — uses the §4 candidate-state pattern to give the atomicity guarantee the user asked about ("how can we guarantee a successful migration"): either complete or no-op, never a half-migrated state. LOC count is irrelevant; the substrate handles 10 sites or 10,000 the same way. - **Affected-LOC enumeration** — pre-execution preview of site_count + exact_paths + re_exec_scope, structurally, not by grep. Direct answer to the user's "what are all the affected LOC" question. - **Composes per-lens transforms from §6.2** — a mechanical refactor often decomposes into per-lens auto-fixes from the L1.x catalog. Canonical-B decomposes into L1.7 transforms + L1.12 outcome (4) transforms. Agent picks the named refactor; substrate composes the per-lens transforms that implement it. - **PR #3338 as the worked example** — canonical-B across 6 languages + 7 v3 ratchet dissolutions, two operator decisions ("use decl-ref for Bool" + "dissolve the 7 v3 ratchets") plus 13 uniform per-class site applications. Hand-executed in #3338; the substrate (had it been operational) could have applied the entire refactor mechanically from those two decisions. §6.9 recommended ordering updated: (f) mechanical refactor slots between (b) L1.12 and (c) interface cascade — it's the most directly useful hero shape for day-to-day refactoring work, and demonstrates the composition pattern that the agent-shape cases (c)/(d)/(e) build on. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * design-read-edit-pipeline: fix §6.10 RootScope slip — use the §2 corpus-fold idiom cursor/composer-2 review caught a slip: §6.10 wrote `auto_fix_for_lens(L1.5, RootScope)` while §2 (lines 74-77) explicitly rules out RootScope as a scope variant ("no separate RootScope / corpus-wide variant — corpus-wide application is achieved by composition over the declaration set"). Replaced the RootScope call with the explicit fold over `declarations_in(dag)`: declarations_in(dag).for_each(d => auto_fix_for_lens(L1.5, DeclarationScope(d)) ) Added clarifying sentence: "auto_fix_for_lens itself takes a SectionRef (DeclarationScope or NodeScope) — never an invented RootScope." Keeps the doc internally consistent on the single structural scope vocabulary per INVARIANTS P2 / Practice 5. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * design-read-edit-pipeline: track L1.12 concept-identity carriers as §6.8 item 8 + §6.4 dependency caveat codex BLOCKING (sha:77469d84) raised two findings; one valid, one factually wrong. **Finding 1 — valid.** L1.12 concept identity depends on undeclared registry carriers (CanonicalConcept, ConceptDisambiguation, HistoricalDeclaration). Verified absent from src/v4/std/*.dag, src/v4/lens/*.dag, src/v4/extdeps/*.dag — they only exist as design in docs/design-dissolution-lens.md (PR #3334, operator manual-merge queue), not as ratified .dag substrate. Fix: - Added §6.8 item 8 explicitly tracking the L1.12 concept-identity carriers as missing substrate (alongside item 1 machine-readable Clean shapes, item 2 ConditionalDiff ADT, etc.). Lists the three carrier shapes and notes the design-pending status. - Added a dependency caveat callout at the top of §6.4 hero case (b) pointing at §6.8 item 8 so a reader hitting the example sees the carrier-not-yet-substrate dependency immediately. Finding 2 — factually wrong (rebutted on-PR, not in this commit). THESIS.md:232 explicitly carries the retraction with the "operator-ratified 2026-05-15" stamp. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * design-read-edit-pipeline: add §5 Example B dependency caveat matching §6.4 Same finding fired again at line 255 of pre-fix sha (§5 Example B "rename a concept across the corpus", which also references CanonicalConcept). The global §6.8 item 8 + §6.4 inline caveat from 07d862f cover the case, but a reader entering at §5 Example B should see the dependency callout immediately — same shape as the §6.4 callout. Both inline caveats point at §6.8 item 8 as the global tracking entry. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: PM * design-read-edit-pipeline: candidate root explicit in gate surface + LOC rename openai-pro REQUEST_CHANGES on f3d146b raised two valid design-level findings; both addressed. **Finding 1 — candidate authority not typed into gate surface.** The candidate-state pattern from earlier was correct in intent, but the worked examples called `apply_lens(_, ref, Enforce)` with a bare ref — leaving the candidate-vs-pre-edit context to a prose comment ("evaluated in candidate_dag context"). A worker following the pseudo-code could accidentally enforce against the wrong root. Fix: introduce `scope_in(root: Node, ref: NodeRef) -> SectionRef` as the helper that **explicitly binds a frontier ref to a dag root**. Updated §4 pipeline + §5 Example A + §6.3 catamorphism + §6.6 CLI + §6.7b mechanical refactor — every gate call now reads `apply_lens(_, scope_in(candidate_dag, ref), Enforce)`. The candidate root is structurally visible in every call; can't be lost via comment-level convention. **Finding 2 — "affected LOC" reintroduces file/line authority before Node→File binding exists.** §6.7b promised "affected LOC" structurally — but §1 explicitly says file/line is emergent-not-substrate. Promising LOC enumeration before the Node→File binding registry (§6.8 item 6) is built contradicts the node-centric framing. Fix: rename §6.7b "Affected-LOC enumeration" → "Affected-structural- paths enumeration"; the inline preview computes structural Paths, not file:line. Added a callout explicitly tying the LOC translation to the Node→File binding registry (§6.8 item 6) — until that registry lands, the substrate-native answer is in terms of Paths. LOC is the downstream projection of "affected sites" via emit's mapping; the substrate-native fact is "affected structural sites." Also updated the "guarantee is structural" close-out: "LOC count is irrelevant" → "Site count is irrelevant." Keeps the doc consistent that the substrate-native unit is the Path/site, not LOC. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * design-read-edit-pipeline: fix §6.10 auto_fix_for_lens straggler — scope_in everywhere codex APPROVE_WITH_COMMENTS caught one remaining apply_lens call site I missed in the prior candidate-authority pass: §6.10 auto_fix_for_lens workflow at line 851 still used `apply_lens(lens, ref, Enforce)` with the bare ref. Fixed to `apply_lens(lens, scope_in(candidate_dag, ref), Enforce)` matching §4's "candidate root explicit in the gate surface" rule and the rest of the worked examples. Verified: only remaining `apply_lens(_, ref, Enforce)` in the doc is the §4 anti-pattern call-out itself (explaining what NOT to do). All actual call sites are consistent.
