…p across extdeps/languages (A-vs-B = B / ruled-B)

Supersedes the disposition rows that framed the now-rejected hollow
grounding shape as canonical, so two contradictory dispositions do not
stand against the landed ruled-B exemplar:

- DECISIONS.md CppBool: 🟢 GREEN terminal → 🟡 deferred to
  feature:t4-cpp-scalar-ladder (bool lands structurally as
  CppScalar.BoolScalar; hollow alias was never a real 🟢).
- DECISIONS.md rust.dag/RustNever + python singleton row: bare alias /
  {spelling}-GroundingMap retired; grounding is a fold-discharged
  structural coincidence (RustScalar.NeverScalar/BoolScalar,
  PythonNumericTower.BoolLevel); GroundingMap home moot.
- INVARIANTS §P2 receipt: GroundingMap twin retired from every
  extdeps/languages slice (machine_code already; now rust/cpp/lean);
  only the lean.dag/machine_code Symbol twin remains P2-staging.

Anchors the canonical single-valued/uninhabited exemplar at
docs/modeling/grounding-worked-examples.md §0.

…e-readable grounding edge

Addresses the PR #3338 exploratory review note (dead RustBool/RustNever
names in §0) and an operator-flagged accuracy defect: §0 and the ledger
rows asserted RustScalar.BoolScalar / PythonNumericTower.BoolLevel as
"structural grounding," but a bare nullary classifier variant has no
fold-traversable edge to std Bool/Never — by the machine-readable-
inhabitance bar that is "basically nil," the same hollow class as the
retired {spelling} GroundingMap.

§0 now separates the two artifacts: (1) the classifier fact (present,
honest surface enumeration — same as machine_code/ptx carry); (2) the
machine-readable grounding edge (NOT present in any extdeps slice;
exemplar = std/logic.dag's real bool_boolean_algebra instance) — and
flags A-vs-B (deletion-only + deferred fold, vs. author the real
grounding instance now) as the OPEN operator-owned canonical-B call.
Substrate-feature determination holds under both readings (no Class-5
gap #3 dependency either way). File Status lines + DECISIONS.md CppBool /
RustNever / python-singleton rows reworded to match — no claim that the
bare tag is the grounding.

Re: cursor/composer-2 review (verdict APPROVE — Findings: None; one exploratory, non-blocking note).

Exploratory note verified and addressed in 7193fcaf9. The note was correct: §0 of grounding-worked-examples.md used RustBool/RustNever type names that rust.dag no longer defines, in the model/coercion discussion. That naming was a symptom of a deeper accuracy defect (independently flagged by the operator): §0 over-claimed the bare nullary classifier variant (RustScalar.BoolScalar, PythonNumericTower.BoolLevel, …) as the machine-readable structural grounding. It is not — a bare classifier tag has no fold-traversable edge to std/logic.dag Bool, which by the machine-readable-inhabitance bar is "basically nil" (the same hollow class as the retired {spelling} GroundingMap).

Fix: §0 now explicitly separates (1) the classifier fact (present — honest surface enumeration, exactly what the D2-REV-clean machine_code.dag/ptx.dag carry for their scalars) from (2) the machine-readable grounding edge (NOT present in any extdeps slice; exemplar = std/logic.dag's real data bool_boolean_algebra instance). The discussion/coercion text now uses bool/! and the live RustScalar.BoolScalar/NeverScalar names; the only type RustBool left is inside the quoted retired form. File Status lines + DECISIONS.md (CppBool / RustNever / python-singleton rows) reworded to match — no claim that the bare tag is the grounding.

Open, deliberately flagged in §0 (not a rubric violation): whether the canonical-B exemplar is (A) deletion-only with the grounding edge deferred to the realized [MODELED] fold (consistent with the named clean refs, which also carry no edge), or (B) a real fold-traversable grounding instance authored now (modeled on bool_boolean_algebra). That is an operator-owned modeling-shape decision pending; the substrate-feature determination holds under both (no Class-5 gap #3 dependency either way).

Correction to my prior comment (record accuracy / P0). The last paragraph above stated: "the substrate-feature determination holds under both (no Class-5 gap #3 dependency either way)." That is retracted — it is disproven by compiler verification.

Implementing reading B (a real machine-readable grounding instance data <lang>_bool_grounding: BooleanAlgebra<Bool> = <2-element boolean algebra>, modeled on std/logic.dag's bool_boolean_algebra) across the 6 extdeps slices fails to compile in user-range .dag, both expressible forms:

  • decl-ref body = bool_boolean_algebra → data has an opaque body … class-5 gap #3 (decl-ref data bodies do not lower today).
  • structural literal = BooleanAlgebra { …fn/match… } → Parse error: expected primary expression, got KwFn (the block-body/lambda grammar gap — Class-5 gap . #3's named sibling). std/logic.dag compiles only via the bootstrap path; extdeps files are user-range.

Corrected determination: canonical-B is a build-it-first — it requires either decl-ref-data-body lowering (the smaller unlock; enables the M2-clean shared-authority = bool_boolean_algebra form) or fn/match-in-data-body grammar. That is substrate/grammar-capability work, out of this PR's scope, not shimmed inline per the standing "substrate work waits for the substrate primitive" discipline.

This PR remains at the honest Reading-A state at 7193fcaf9 (D2a hollow forms removed; classifier fact kept; §0 + ledger flag B as the open canonical-B call) — that part is unaffected and accurate. The A-vs-B-vs-build-it-first direction is an open operator-owned decision; not a rubric finding. No code change in this comment; correcting the public record only.

Re: openai-pro/gpt-5.5-pro REQUEST_CHANGES (review 14405, sha 7193fcaf). Verdict noted and not dismissed — but the artifact available to me (/api/reviews/14405/artifacts/stdout.log) contains only the reviewer harness startup log (login check, context-file uploads, prompt fill, ending at [typing] keystrokes done — pausing pre-send…); it carries no findings/verdict body, and no GitHub review object/body was posted (gh pr view --json reviews empty; comment_url: null). I cannot verify-and-fix findings that are not present in any retrievable artifact, and I will not guess at them.

Current accurate state of this PR for the reviewer's benefit: it is the honest Reading-A slice at 7193fcaf9 — the D2a bare-alias + {spelling}-GroundingMap hollow forms are removed; the classifier sum-variant fact is kept; §0 of grounding-worked-examples.md + the DECISIONS.md/INVARIANTS.md rows explicitly flag that the machine-readable grounding edge (canonical-B) is not present and is an open, operator-owned, build-it-first item (compiler-verified: a real data x: BooleanAlgebra<Bool> = … grounding instance cannot be expressed in user-range extdeps .dag today — decl-ref body → Class-5 gap #3; fn/match literal body → block-body grammar gap; see prior comment issuecomment-4482987434). No hollow claims remain; CI green; mergeable=CLEAN.

If the actual findings are relayed (or posted as a review body), I will verify each against the code and fix or rebut specifically. Please surface the findings text.

Re: BLOCKING inline review at src/v4/extdeps/languages/lean.dag:5 (briansrls, 23:12:21Z) — finding verified valid; fixed in 8128a5992.

You were right: I reconciled the CppBool / RustNever / python-singleton rows + the INVARIANTS §P2 receipt to ruled-B, but missed DECISIONS.md:264 (the LeanScalar ledger row), which still asserted "kernel LeanBool = Bool + lean_bool_grounding cites std coincidence for the kernel bool spelling only (D2-REV)" — two contradictory authorities for the same grounding (P2 / Practice 9), exactly as flagged. Now reconciled: that row states the D2a LeanBool = Bool + lean_bool_grounding is retired (ruled-B); LeanScalar.BoolScalar is the classifier fact; the machine-readable grounding edge is the open build-it-first canonical-B call (§0); the per-file GroundingMap twin is retired (cf. INVARIANTS §P2).

Proactively swept the whole class in the same commit: DECISIONS.md:902 (the TS row still presenting type TsBoolean = Bool as a current D2-shaped bridge) had the identical contradiction against typescript.dag — reconciled the same way (the non-bool number/string/symbol/null/undefined debt stays 🟡-gated, unaffected). Re-scan confirms no remaining retired-shape-as-canonical assertion in DECISIONS.md/INVARIANTS.md (all residual mentions now carry explicit retired/removed framing). MachineScalar:288 was already consistent (it correctly says aliases are omitted).

If the +2 queued inline items are the TS/Cpp analogues of this same class, they are addressed by this commit; I'll verify each against the code as they relay.

Blocking inline review (typescript.dag:3): the per-file TS findings row
scoped remaining scaffolds to "Non-Bool D2a(1)" (so not contradictory)
but did not explicitly record the Bool D2a(1) alias as retired, leaving
single-authority implicit. Now states TsBoolean=Bool is retired
(ruled-B), not in the remaining-scaffold set, and points to the TS-D2 §
as the single disposition authority. The TS-D2 § + the 902 bullet were
already reconciled in 8128a59 (relay arrived post-fix).

Re: BLOCKING inline review at src/v4/extdeps/languages/typescript.dag:3 (briansrls, 23:12:21Z) — verified; addressed.

Verified against current HEAD (not dismissed as stale):

  • The core assertion the finding flags — DECISIONS.md TS-D2 ledger stating type TsBoolean = Bool is remaining D2 debt — was the 902 bullet, already reconciled in 8128a5992 (relay arrived after that fix, the post-fix-relay case). The named TS-D2 § (lines 874–912) now states TsBoolean = Bool is retired/removed (ruled-B); machine-readable grounding edge = open build-it-first canonical-B (§0). No assertion of it as live debt remains in that section.
  • The per-file findings row at DECISIONS.md:123 already scoped remaining scaffolds to "Non-Bool D2a(1)" (so it did not assert TsBoolean=Bool as debt) — but it left single-authority implicit. Tightened in e332fa2e1: it now explicitly records TsBoolean = Bool as retired (ruled-B), not in the remaining-scaffold set, and points to the TS-D2 § as the single disposition authority.

Net: typescript.dag:3 (TsBoolean dropped from Owns) and the TS ledger (TS-D2 § + line 123) are now single-authority and mutually consistent under P2 — the retired-alias state is asserted in exactly one authoritative place and cross-referenced, not duplicated or contradicted.

… the removed twin only

cursor/composer-2 exploratory note (review 14422): "the GroundingMap→
resolver.dag trigger is moot" was easy to misread as cancelling D4 /
shared resolver.dag work entirely. Reworded: the per-file-twin
*relocation* obligation is obsolete *for the removed twin shape* (twin
deleted, not relocated); explicitly does not cancel/supersede/bear on
any independent shared-resolver.dag / D4 work. Non-blocking clarity fix.

The note was valid and is addressed in 12f833c27: the INVARIANTS §P2 sentence "the GroundingMap→resolver.dag trigger is moot" is reworded to scope it strictly to the removed per-file twin (twin deleted, not relocated) and to state explicitly it does not cancel/supersede/bear on any independent shared-resolver.dag / D4 work — removing the mis-parse risk the reviewer flagged.

…ll 6 (v2-verified)

Implements reading B via the v2-verified decl-ref form
`data <lang>_bool_grounding: BooleanAlgebra<Bool> = bool_boolean_algebra`
(references the single std/logic.dag authority — M2-clean) in rust /
cpp / go / lean / python / typescript. Rust `!` = `type RustNever =
Never` (direct primitive identity). Python carries the int-subtype
build-up note (PythonNumericTower.BoolLevel) — first iteration.

Verified against the REAL bootstrap gate (v2-compiler compile
--source-root src/v4, ci.yml v4: job): 72 modules resolved, 0
diagnostics. Parse/resolve-verified; v2-run T-22-deferred (not
execute-verified — claimed no further).

Doc §0 reframed: dropped "quirked"; one universal grounding discipline
(reference the shared authority for what the spec shares, build up from
primitives where the spec deviates); bool-vs-int level spectrum; honest
v2 scope. DECISIONS.md (CppBool 🟡→🟢-grounded, LeanScalar, TS-D2 §,
line 123, python, rust/RustNever) + INVARIANTS §P2 flipped from "open
canonical-B call" to LANDED. Frozen v3-smoke incompatibility is a
tracked governance followup (v3 not in bootstrap chain), not edited
here.

Re: codex/codex-default review 14430 (sha 12f833c2) — artifact verdict is APPROVE, "No concrete violations observed"; no findings, nothing to fix. Two notes for the record: (1) it reviewed the pre-canonical-B sha 12f833c2 (Reading-A); the later commit a73071728 only strengthened the same direction — decl-ref shared-authority grounding now LANDED and v2-bootstrap-verified (0 diagnostics, v2-compiler compile --source-root src/v4), so the "still only modeled vs mechanically demonstrated" honesty the reviewer credited is now further on the demonstrated side. (2) This APPROVE registered as verdict unknown in the dashboard tally (artifact-parse), so it is not counting toward the 2-distinct-approval gate even though it is substantively an approval — flagging so the readiness count isn't under-stated. — sent from keen-bat-577

… — bundled with canonical-B

Operator-authorized 2026-05-18 (via PM sunny-wolf-435): v3 is FROZEN
2026-05-15 and not in the v2->v4 bootstrap chain; its interim isolated
compile_to_dag smoke ratchets are dead weight and incompatible with the
decl-ref canonical-B grounding. P5 = dissolution, not deactivation:
fully delete, don't disable.

Dissolved (each: .rs + integration.rs mod + INVARIANTS §P5(b) row +
sg0_census EXPECTED_HAND_AUTHORED_TEST row):
  v4_extdeps_cpp_abi / cpp / typescript / machine_code / lean

INVARIANTS §P2 narrative updated to record the dissolution + name the
replacement gate.

RETAINED (verify-don't-trust the relayed list): v4_lens_cost — the PM
list named "v4_lens_coverage" (held PR #3318, absent here); the branch
instead has v4_lens_cost, a distinct P9/T-12 cost-lens authority ratchet
(not a decl-ref-blocking extdeps parse smoke). Held pending explicit PM
confirm rather than exceeding authorized invariant-surface scope.

Replacement gate (no coverage loss): CI v4: job
`v2-compiler compile --source-root src/v4` — v2->v4 bootstrap-viability
per STRUCTURE.md, the authoritative v4 parse check.

Verified: v2 v4: 0 diagnostics (72 modules, decl-ref B all 6);

Re: codex/codex-default REQUEST_CHANGES (review 14439) — finding verified VALID; fixed in d88543049 (not rebutted).

You are right: per INVARIANTS P2 / E-6, a data declaration with no same-PR generated consumer is staging, not landed authority. This PR adds data <lang>_bool_grounding: BooleanAlgebra<Bool> = bool_boolean_algebra but nothing consumes it — the canonical/coincidence fold (the consumer) is specified-not-realized (node.dag B1-CANON contract; [MODELED]). "v2-verified" only ever meant parse/resolve-verified (0-diag under the v2 bootstrap gate), which is not the landed-authority bar. The "LANDED / realized / grounded (canonical-B, v2-verified)" wording overclaimed; I won't argue it.

A real consumer cannot be added in this PR (it is the unbuilt fold — out of scope), so the honest fix is the wording downgrade, applied consistently across all sites: the 6 .dag Status lines, INVARIANTS §P2 (:170), DECISIONS.md (TS table :123, LeanScalar :264, CppBool — now 🟢→🟡 staging, TS-D2 §, python, rust/RustNever), and grounding-worked-examples.md §0. Each now states: the canonical-B decl-ref declaration is present and v2-parse/resolve-verified, but is P2/E-6 STAGING — not landed authority, consumer-gated (fold specified-not-realized). The modeling shape/direction is unchanged; only the authority-state claim is corrected to honest staging. Residual-overclaim scan: clean.

…anded ruled-B ts_bool_grounding

Blocking inline review (DECISIONS.md:123): the TS ledger row still
said "D2a(2) GroundingMap remains 🟡 operator-pending ... no local
GroundingMap or ts_*_grounding rows may be declared" AND (tail) "D2a(2)
rows are blocked only by the shared GroundingMap authority decision" —
both contradict this PR landing ts_bool_grounding, leaving two
authoritative states under P2.

Reconciled: the {spelling}-GroundingMap shape is RETIRED under ruled-B
(no pending shared-P2-home — removed, not relocated; cf. INVARIANTS §P2).
Local GroundingMap type + {spelling}-style ts_*_grounding:GroundingMap{}
rows stay forbidden (the hollow form); the ruled-B decl-ref
ts_bool_grounding: BooleanAlgebra<Bool> = bool_boolean_algebra is a

Re: BLOCKING inline review at src/v4/DECISIONS.md:123 (briansrls, 00:31:28Z) — finding verified VALID; fixed in e8e9f9268.

You're right: the TS ledger row carried two clauses contradicting the landed ts_bool_grounding — (1) "D2a(2) GroundingMap remains 🟡 operator-pending ... no local GroundingMap or ts_*_grounding rows may be declared" and (2) the tail "D2a(2) rows are blocked only by the shared GroundingMap authority decision". Both predate ruled-B and leave two authoritative states under P2.

Reconciled both: the {spelling}-GroundingMap shape is retired under ruled-B — no pending "shared P2 home" because it's removed, not relocated (consistent with INVARIANTS §P2's GroundingMap→resolver.dag relocation-obsolete clause). A local GroundingMap type and {spelling}-style ts_*_grounding: GroundingMap{…} rows stay forbidden (the hollow form). The ruled-B decl-ref ts_bool_grounding: BooleanAlgebra<Bool> = bool_boolean_algebra is a distinct, sanctioned shape (single std-authority reference, not a GroundingMap row) — declared this PR, P2/E-6 staging (consumer-gated); single-authority disposition is the TS-D2 §. Residual-scan for the GroundingMap-pending/forbidden contradiction class across DECISIONS.md + INVARIANTS.md: clean. This was the same stale-clause class as the earlier Lean:264 / TS-D2:902 catches — I'd missed this specific D2a(2) clause; now consistent.

Re: codex/codex-default BLOCKING (review at sha 9fac0447) — finding verified VALID; already addressed at HEAD e8e9f9268 (post-fix relay; the bot reviewed a pre-fix commit).

This is the same contradiction the operator's inline review at DECISIONS.md:123 flagged; fixed last commit. Verified on current HEAD:

  • The D2a(2) clause now reads: "the {spelling} GroundingMap shape is retired under ruled-B — there is no 'shared P2 home' pending because the shape is removed, not relocated (cf. INVARIANTS §P2)". The pre-ruled-B "remains 🟡 operator-pending … no local GroundingMap or ts_*_grounding rows may be declared" prose is gone; the tail "blocked only by the shared GroundingMap authority decision" is superseded too.
  • ts_bool_grounding: BooleanAlgebra<Bool> = bool_boolean_algebra is now identified as the single ruled-B canonical-B receipt (decl-ref to the std authority, P2/E-6 staging — consumer-gated), with the TS-D2 § as single-authority disposition.
  • Non-bool D2 deferrals are scoped separately in the same row (TsNumber = Float64, TsBigInt = Int, TsString = String, symbol/null/undefined remain 🟡 tracked scaffolds).
  • Residual GroundingMap-pending/forbidden-contradiction scan across DECISIONS.md + INVARIANTS.md: clean.

That is precisely the requested rewrite (retire spelling-only GroundingMap rows; identify ts_bool_grounding as the canonical-B receipt; scope non-bool D2 deferrals separately). No further change needed.

Re: cursor/composer-2 review 14445 — verdict APPROVE_WITH_COMMENTS; the one comment (DECISIONS.md:123) is already addressed at HEAD e8e9f9268 (post-fix relay — cursor reviewed a pre-fix commit; same finding as the operator's inline review + codex, all fixed last commit).

Verbatim current DECISIONS.md:123 D2a(2) clause on HEAD:

D2a(2): the {spelling} GroundingMap shape is retired under ruled-B … A local GroundingMap type and {spelling}-style ts_*_grounding: GroundingMap{…} rows remain forbidden (the hollow form). The ruled-B decl-ref ts_bool_grounding: BooleanAlgebra<Bool> = bool_boolean_algebra is a different, sanctioned shape (single std-authority reference, not a GroundingMap row) — declared this PR, P2/E-6 staging (consumer-gated); single-authority disposition is the TS-D2 § below.

That is exactly the requested tightening: it makes explicit that forbidden = GroundingMap spelling/resolver-twin rows (ts_*_grounding: GroundingMap{…}), and that the top-level decl-ref data ts_bool_grounding: BooleanAlgebra<Bool> = bool_boolean_algebra is explicitly allowed/sanctioned (distinct shape, not a GroundingMap row). The ledger can no longer be read as forbidding what the PR lands. Residual GroundingMap-pending/forbidden-contradiction scan across DECISIONS.md + INVARIANTS.md: clean. Thanks for the APPROVE on the substance (canonical-B decl-ref + P2/E-6 staging honesty + 7 v3-smoke dissolution with the v2 v4: replacement gate). The exploratory §P2-split suggestion is noted as non-blocking future maintainability.

D5 reconcile receipt: operator A-vs-B ruling (2) plus operator-executed #3338 moved the C++ slice past the frozen #3277 scaffold, so this advances the #3277 branch to post-#3338 main and resolves cpp.dag forward to the ruled-B fact-bundle shape.

Resolution: preserve #3267 cpp_abi as the width authority and model CppScalar with integer surface spelling, CppTargetProfile, CppTargetDataModel, ABI-selected CppIntegerWidth, signed two's-complement representation, and overflow/range disposition. Do not restore the stale hollow CppBool=Bool reduction, do not add a local GroundingMap row, and do not revert merged main work.

… 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.

briansrls added a commit that referenced this pull request May 19, 2026
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.

…3229-* form (#3352)

The `CppIntegerOverflowDisposition` coproduct in `extdeps/languages/cpp.dag`
carried the non-conforming tag `// 🟢 coproduct dissolution — DECISIONS.md
T29-ABI + D2-REV.`, which predates and violates the in-file one-liners
directive (DECISIONS.md Part 6: every sum coproduct carries one
`// 🟢|🟡|🔴 coproduct dissolution — DECISIONS.md Part 6 · <CP-3229-*|SL-3229-*>`).

`cpp.dag` was created post-merge-base (PR #3199), so it cannot use the
merge-base-only `CP-3229-GREEN-TERMINAL` bulk slug. A dedicated Part-6 row
`CP-3229-CPP-INTEGER-OVERFLOW` is added — same shape as the post-merge-base
`CP-3229-NAT-LE-WITNESS` precedent — classifying the coproduct 🟢 GREEN

* 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.

* L1.12 F9 snippet: show existing classification tags, sharpen authority gap

cursor/composer-2 review noted that the F9 "Concrete match" block
implied both `dsl/std/types.dag` and `src/v4/std/logic.dag` were bare,
when both files actually carry annotations above their `type Bool` line
(legacy-scanner anchor prose in dsl/std/types.dag:163-172;
🟢 coproduct-dissolution classification tag at src/v4/std/logic.dag:13).

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. L1.12 specifically requires a designator that picks a
canonical winner, which is the gap classification tags don't fill.

* 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.

* 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.

* 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.

* 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.

* 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.

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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

…#3290 redo on post-#3338 main) (#3350)

* v4 de-prose: bind typescript.dag into strict_deprose_dag.py allowlist (#3290 redo on post-#3338 main)

Refreshed against post-#3338 main rather than the stale proud-bat-880 branch:
#3338 rewrote the comment surface and already landed ts_bool_grounding canonical-B
decl-ref. This PR is the merge-gate binding step — adds typescript.dag to the strict
de-prose allowlist (scripts/strict_deprose_dag.py specs / CI ci.yml:104 --check),
normalizing the header to the script's required form (path / Scope / Owns / Consumes
/ Status / Anchor / Ledger), and moving the per-coproduct 🟢 tag from
between-`type`-and-`=` to the script-canonical position above the `type` line so
`inject_coproduct_tags` is an idempotent fixed point under --check.

Carrier surface byte-identical (comment-only diff): same imports, same two N≥2 sum
coproducts (TsEcma262NumericPrimitiveKind, TsEcma262PrimitiveOperationSemantics,
both 🟢 CP-3229-GREEN-TERMINAL per merge-base 92cb264), same
`data ts_bool_grounding: BooleanAlgebra<Bool> = bool_boolean_algebra` row.

Rust-to-0 binding: no per-language Rust smoke test added; the pre-existing
v4_extdeps_typescript_dag_smoke_test.rs was removed by #3338 and stays removed.

Test plan:
- `python3 scripts/strict_deprose_dag.py --check` → OK (allowlist incl. typescript).
- `diff <(grep -vE '^\s*//|^\s*$' pre) <(grep -vE '^\s*//|^\s*$' post)` empty → carriers unchanged.
- v2-compiler `compile --source-root src/v4` diagnostic count preserved (no carrier mutation; CI v4 job re-verifies).

* fix: align typescript.dag Status header with DECISIONS.md authority (codex #3350 review)

Codex review flagged the Status line "bool canonical-B decl-ref grounding landed (#3338)"
as overstating closure — DECISIONS.md:916-920 explicitly classifies `ts_bool_grounding`
as 🟡 P2/E-6 STAGING (not landed authority; no same-PR consumer; canonical fold
specified-not-realized). Restore the 🟡 STAGING wording with the DECISIONS.md anchor
so the header matches the live ledger (INVARIANTS.md P2 / Practice 9 "documentation
describes live state").

* fix: register typescript.dag in DECISIONS.md Part 6 CP-3229-GREEN-TERMINAL recovery table (#3350 BLOCKING)

briansrls inline review @ typescript.dag:14 — the live `// 🟢 coproduct dissolution
— DECISIONS.md Part 6 · CP-3229-GREEN-TERMINAL.` tags weren't mechanically traceable
because the Part 6 bulk-recovery table did not list typescript.dag. Add the row
(`typescript.dag | 2` matches `git show 92cb264:typescript.dag | grep -c "GREEN
(terminal)"`) and the recovery `git show` line. No code/script change needed —
the strict-deprose tag map already classifies both TS coproducts as 🟢 GREEN from
the merge-base authority block; this is the missing inventory anchor.

* fix(merge): update typescript.dag entry to main's 6-tuple spec (RULING-1 slice marker)

Post-merge fix on top of 22b1854: main rewrote the strict_deprose_dag.py spec
tuple to 6-fields (added RULING-1 per-slice groundedness emoji) and updated the
canonical separators (`// Ledger: <slug>.` drops "dissolution slugs (PR #3229):";
coproduct tag uses `·` not `—`). Updated the typescript.dag spec to add the
extdeps `// 🟡` slice marker and re-materialized the file to match canonical
output. `python3 scripts/strict_deprose_dag.py --check` → OK.
