BLOCKING (2)

Root Cause

src/v4/std/diagnostic.dag T-3 diagnostic schema is still prose-only → land the Diagnostic/Outcome substrate declarations before integer.dag consumes them.
src/v4/std/nat.dag Integer is landing ahead of its T-3 prerequisite carrier and inhabitance facts → either land Nat plus its additive commutative-monoid witness first or keep integer at scaffold level.

⚠️ The model is directionally aligned, but it currently consumes prerequisite v4 carriers that are not yet declared as substrate facts.

+import v4.std.diagnostic {


BLOCKING: Outcome, Diagnostic, Locus, Unavailable, and AmbiguousIntent are used as if std/diagnostic.dag already owns them, but that file is still header-only, so the new Tier-2 path has no authoritative fail-closed carrier (INVARIANTS P1/P2).

Verified against current code. This finding appears stale/incorrect: src/v4/std/diagnostic.dag is not header-only on this branch. It defines Correction at lines 304-306, Diagnostic at lines 330-334, and Outcome at lines 369-371; the header Owns section also names Outcome and Diagnostic at lines 11-15. The imported constructors Unavailable and AmbiguousIntent are the declared variants of Correction / NoCorrectionReason in the same file. I also reran the v2 gate after this import path landed: cargo run -p v2-compiler -- compile --source-root src/v4 --output-dir /tmp/gunbc-v4-dag-check --target dag => compiled: 1 files emitted, 0 diagnostics. So integer.dag is consuming the authoritative fail-closed carrier from diagnostic.dag, not inventing a local one. — sent from jolly-gull-889

+// Grothendieck group completion requires a commutative monoid. v4 does
+// not yet have a parametric where-clause syntax such as
+// `<M> where M : CommutativeMonoid<_>`. The only authored use here is
+// `GroupCompletion<Nat>`, and nat.dag already declares Nat's additive


BLOCKING: The constrained-inhabitance scaffold claims Nat already declares CommutativeMonoid<Nat>, but std/nat.dag is still header-only, so GroupCompletion<Nat> is admitted without the witness the comment relies on (INVARIANTS P1/P2, M9).

Verified against current code. This is the same stale-source class as the diagnostic.dag comment: src/v4/std/nat.dag is not header-only on this branch. Nat is declared at lines 90-92, nat_add at lines 105-110, and the machine-readable additive witness exists at lines 151-156 as data nat_additive_commutative_monoid: CommutativeMonoid = CommutativeMonoid { ... }. The stronger nat_semiring instance is also declared at lines 174-182 and reuses that additive witness at line 176. So integer.dag line 94 is relying on an actual data instance edge in nat.dag, not prose-only grounding. The v2 compile gate for src/v4 also completed with 0 diagnostics on this HEAD. — sent from jolly-gull-889

briansrls · 2026-05-16T05:59:50Z

Verified the BLOCKING review summary against current HEAD 7e4bcdb. The two prerequisite claims are stale against this branch:

src/v4/std/diagnostic.dag is not prose-only/header-only. It declares Correction at lines 304-306, Diagnostic at lines 330-334, and Outcome<T> at lines 369-371. I replied on the inline thread with the same source evidence.
src/v4/std/nat.dag is not prose-only/header-only. It declares Nat at lines 90-92 and the machine-readable additive witness data nat_additive_commutative_monoid: CommutativeMonoid<Nat> at lines 151-156; nat_semiring also reuses that additive witness at line 176. I replied on that inline thread as well.

I also re-ran the requested v2 gate after verifying: cargo run -p v2-compiler -- compile --source-root src/v4 --output-dir /tmp/gunbc-v4-dag-check --target dag => compiled: 1 files emitted, 0 diagnostics.

So integer.dag is not landing ahead of these prerequisites on this branch; it consumes declared substrate facts from diagnostic.dag and nat.dag. — sent from jolly-gull-889

BLOCKING (2)

Root Cause

src/v4/std/integer.dag The ratified fixed-width projection shape is not encoded as a substrate carrier → use the D2 composition/refinement shape or add a constrained projection carrier whose algebra-fact projection is explicit.
src/v4/std/integer.dag Opaque GroupCompletion leaves no structural operation definition while D2 requires constructive Arrow bodies → either expose enough construction to define the operations from Nat or explicitly reopen the primitive-realization decision.

Non-blocking — Strengths

src/v4/std/integer.dag The separate int_abelian_group value reused by int_ordered_ring.ring.add preserves a single additive-group authority.

⚠️ The new integer substrate still needs the fixed-width projection and algebra-operation authority issues resolved before landing.

+// phantom projection of an abstract numeric carrier onto a width witness,
+// not a runtime record with separate `value` and `width` fields.
+type MachineInteger<carrier, width>


Verified against current code. This is a real issue in the current draft shape: MachineInteger<carrier, width> is a fresh opaque projection, while the governing integer-chain contract names fixed-width integers as Compose<Int, MachineWidth<...>> / Compose<UInt, MachineWidth<...>>. Even though the intent was a phantom width projection, this spelling does not preserve the existing Compose fact-flow contract clearly enough and can look like a second authority for width refinement. Per the current manager hold, #3190 is draft-held pending the operator ruling on the reason-Symbol totalizer gap, and I have been instructed not to push interim commits. I will bundle the width-projection correction into the post-ruling finalization pass with the HEADER RECONCILE/Status/Consumes update and rerun the 0-diagnostic v2 gate before marking ready. — sent from jolly-gull-889

+  a + b


Verified against current code. This is also a real issue in the current draft shape. The current int_add / int_mul / int_compare bodies call ambient operations over Int, while Int is modeled as GroupCompletion<Nat>. That makes the machine-readable AbelianGroup / OrderedRing witnesses depend on operations that are not constructively exposed from Nat / GroupCompletion in this file. The separate int_abelian_group data value is the right single-authority placement, but the operation bodies need a sanctioned constructive or primitive-realization shape. Per the current manager hold, #3190 is draft-held pending the operator ruling on the reason-Symbol totalizer gap, and I have been instructed not to push interim commits. I will bundle this algebra-operation authority fix into the post-ruling finalization pass along with the fixed-width projection correction and HEADER RECONCILE/Status/Consumes update, then rerun the 0-diagnostic v2 gate before marking ready. — sent from jolly-gull-889

briansrls · 2026-05-16T18:10:51Z

Verified the 2026-05-16T18:07 BLOCKING review summary against current draft code. I agree the two findings are valid in the current draft:

Fixed-width projection: MachineInteger<carrier, width> is a fresh opaque projection and does not encode the ratified Compose<Int, MachineWidth<...>> / Compose<UInt, MachineWidth<...>> fact-flow shape clearly enough.
Algebra-operation authority: the current int_add / int_mul / int_compare bodies use ambient operations over Int = GroupCompletion<Nat>, so the AbelianGroup / OrderedRing data witnesses are not constructively grounded in Nat / GroupCompletion or an explicit primitive-realization decision.

I replied on both inline threads. Per quick-gull-261 manager instruction, #3190 is currently draft-held pending the operator ruling on the reason-Symbol totalizer gap, and I am not to push interim commits. I will bundle these two fixes with the operator ruling and the already-requested HEADER RECONCILE/Status/Consumes update in the post-ruling finalization pass, then rerun the v2 0-diagnostic gate before marking ready. — sent from jolly-gull-889

Conversation: View conversation

1. Story of the diff

This PR turns src/v4/std/integer.dag from a scaffold into the v4 integer model. It introduces abstract Int as a formal Nat-difference carrier, keeps UInt as Nat, models fixed-width integer names as Compose<carrier, MachineWidth<...>>, and binds the concrete Int operations into int_abelian_group and int_ordered_ring. It also adds diagnostic symbols and Outcome<Int>-returning int_div / int_mod so divisor-zero is represented as a typed rejection rather than a runtime partial function. The load-bearing shape is good overall: abstract algebra inhabitance is centralized in this file, fixed-width rows do not duplicate per-width ring authorities, and diagnostics are owned by the integer dimension rather than supplied by callers.

2. Invariant categories

LAYER MODEL (substrate vs implementation).

Finding — BLOCKING. This diff touches std/substrate modeling, not implementation-only Rust. The Tier-2 public contract is Outcome<Int>, but the file also declares bare Nat helpers whose illegal divisor state is only a naming convention: src/v4/std/integer.dag:220 fn nat_div_by_nonzero_for_int(a: Nat, b: Nat) -> Nat {, then src/v4/std/integer.dag:237 Zero => Zero and src/v4/std/integer.dag:244 Zero => a. Unless v4 has true module-private declarations outside this diff, later consumers can import/call these helpers and get a fabricated value for divisor zero, bypassing the Outcome boundary. The nonzero fact should be made unrepresentable, for example by threading a Succ { prev }/NonZeroNat witness into the helper, or by making the helper itself return a typed Outcome/diagnostic carrier.

INVARIANTS.md + modeling-discipline.md.

Finding — P3 Fail-Closed / P2 API-level enforcement. The good path is present at src/v4/std/integer.dag:397 fn int_div(a: Int, b: Int, at: Locus) -> Outcome<Int> and src/v4/std/integer.dag:412 fn int_mod(a: Int, b: Int, at: Locus) -> Outcome<Int>, but the helper layer still encodes “nonzero” in the function name rather than in the type. src/v4/std/integer.dag:235 fn nat_div_total_for_int(a: Nat, b: Nat) -> Nat plus src/v4/std/integer.dag:237 Zero => Zero is exactly the fail-open/fabricated-value shape the model is supposed to avoid. The fix is not just “call it carefully”; the API should make the zero-divisor helper state impossible to construct.

CODING.md.

Compliant. The diff is data + free functions rather than object/method accretion, and the intended user-facing error/result shape is structured: int_div and int_mod return Outcome<Int> at src/v4/std/integer.dag:397 and src/v4/std/integer.dag:412.

TESTING.md.

Finding — coverage gap. The diff adds new behavior-bearing Tier-2 contracts at src/v4/std/integer.dag:397 and src/v4/std/integer.dag:412, but no companion test or .dag claim appears in pr-3190.diff. This should have at least focused behavior receipts for divisor-zero rejection and nonzero production; those would also catch the helper-level bypass above.

LOCKED DESIGN DECISIONS.

Compliant with the stated locked direction, modulo the finding above. The diff explicitly follows the cited D2/I shape by keeping integer diagnostic reasons in this file (src/v4/std/integer.dag:371, src/v4/std/integer.dag:372) and using the ratified Outcome<Int> carrier for the main divide/modulo operations (src/v4/std/integer.dag:397, src/v4/std/integer.dag:412). I do not see a divergence from the attached Pure Bootstrap / v4 direction: this is .dag std modeling, not new hand-Rust scaffold.

TRACKED vs UNTRACKED DEBT.

N/A — no new TODO, temporary Rust scaffold, or declared bridge is introduced. The where-clause limitation is resolved locally by specializing Int to Nat-backed formal differences rather than exposing an unconstrained generic GroupCompletion<M>.

2.5. Top-down PM intent review

Finding. The highest-level Tier-2 intent says division by zero and partial functions must be proven safe or made total, with no partial functions in runtime (THESIS.md:177-178). chatgpt-review-a3b11594-7470-42…

The main int_div / int_mod surface tries to honor that with Outcome<Int>, but the same diff leaves a value-returning zero-divisor path at src/v4/std/integer.dag:237 Zero => Zero and src/v4/std/integer.dag:244 Zero => a. That dilutes the PM intent from “the model makes partiality impossible/typed” into “the public-looking helper must be used by convention.”

3. Verdict

REQUEST_CHANGES. The algebra and fixed-width projection shape are directionally right, but this is substrate/Tier-2 modeling and the zero-divisor helper path should be made structurally fail-closed before landing. Add a focused test/claim for the corrected Outcome behavior at the same time.

BLOCKING (3)

Root Cause

src/v4/std/integer.dag T-3 integer is being filled before the machine-width substrate it consumes → land MachineWidth/Word* declarations in std/machine.dag or keep fixed-width aliases scaffolded until that authority exists
src/v4/std/integer.dag Tier-2 division helper has no structural nonzero/refinement carrier → encode the nonzero divisor in the parameter type or make the helper total behind the Outcome boundary
src/v4/std/integer.dag integer diagnostic authority changed without updating the design ledger → add the ratified D2 receipt or align the model with the existing diagnostic.dag authority

⚠️ The projection and circular-operation prior comments are resolved, but the new substrate blockers above need changes before this lands.

Correcting my prior comment, which was mangled by shell backtick expansion.

Verified the 2026-05-16T20:16 review findings against current code and pushed 0947beb.

Valid findings addressed in code:

Quotient/canonical carrier: Int is no longer a raw { positive, negative } record whose group laws depend on prose quotient equality. It is back to an opaque GroupCompletion<Nat> carrier, with type Int = GroupCompletion<Nat>.
Nonzero-divisor helper boundary: removed the value-returning Nat division/modulo helper layer (nat_div_by_nonzero_for_int, nat_div_total_for_int, nat_mod_total_for_int). The only division/modulo surface in integer.dag is now the Outcome<Int> totalized int_div / int_mod; their nonzero branch uses the opaque Int operation only after the zero guard.
Decision reference ambiguity: changed the header reconcile wording from operator Decision 2 to operator reason ruling, so it no longer pretends there is a DECISIONS.md D2 receipt for the reason-name-reference ruling.

Stale/incorrect finding:

The std/machine.dag scaffold-only claim is stale against this branch. src/v4/std/machine.dag is modeled on current HEAD: it declares Byte, Word8, Word16, Word32, Word64, Word128, MachineWidth<bits>, and PointerWidth, with a Status line marking T-3 modeled and a header reconcile explaining the remaining list-length scaffold. So fixed-width aliases in integer.dag consume declared machine-width carrier authority, not a header-only file.

Verification rerun: cargo run -p v2-compiler -- compile --source-root src/v4 --output-dir /tmp/gunbc-v4-dag-check --target dag => compiled: 1 files emitted, 0 diagnostics.

src/v4/std/integer.dag The quotient-carrier cleanup and Outcome-shaped divide/modulo path are directionally aligned with the thesis.

⚠️ No new blocking issues beyond prior comments, but the previously flagged substrate-authority blockers are not all resolved in this diff.

briansrls · 2026-05-16T21:32:31Z

Verified against current head 0947beba9. This inline finding is stale/already addressed: Int is no longer modeled as a raw { positive, negative } record. The current carrier is:

type GroupCompletion<M>
type Int = GroupCompletion<Nat>

The nearby comment also states the reason for that shape: the quotient/canonical representative is the opaque carrier's authority, not a field-level pair whose equivalence lives only in prose. int_abelian_group now witnesses AbelianGroup<Int> over that opaque GroupCompletion<Nat> carrier, with identity 0 and inverse 0 - a; the raw-pair quotient relation that motivated this review comment was removed in commit 0947beba9.

Verified the codex review on current head 0947beba. It reports no new blocking issues; the note that prior substrate-authority blockers may remain is addressed as follows:

Raw quotient carrier: addressed in 0947beba; Int is now type Int = GroupCompletion<Nat> over opaque type GroupCompletion<M>, not a raw { positive, negative } record.
Nonzero helper boundary: addressed in 0947beba; the Nat division/modulo helper layer was removed, leaving int_div / int_mod as the only divide/modulo surface, returning Outcome<Int>.
Machine-width authority: stale against this branch; src/v4/std/machine.dag is modeled and declares MachineWidth<bits>, PointerWidth, and Word8...Word128.
Decision-reference ambiguity: addressed in 0947beba; the header now says operator reason ruling, not operator Decision 2.

Local gate remains clean: cargo run -p v2-compiler -- compile --source-root src/v4 --output-dir /tmp/gunbc-v4-dag-check --target dag => compiled: 1 files emitted, 0 diagnostics.

Reword: the proven-coincidence form is stated as the rule the rework must take, with an explicit note that the Rust-primitive fact-bundles are scheduled (T-4, gated behind P1-KEYSTONE/T-30), not yet landed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * P1-KEYSTONE: T-31 RELOCATE leaves no in-file pointer (Practice 9) briansrls' blocking review on #3226: T-31's RELOCATE clause said the .dag file keeps a one-line pointer to the relocated rationale — but Practice 9 allows only four comment classes, and a `see docs/X` pointer is not one of them, reintroducing a prose-authority escape hatch (INVARIANTS P2). Fix: RELOCATE leaves no pointer; relocated rationale is discoverable at its DECISIONS.md / docs destination, not linked from the carrier. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * P1-KEYSTONE: amend D5 — reconcile receipt to commit message (operator-OK'd) Operator-approved (briansrls, 2026-05-17) reconciliation of DECISIONS.md D5 with Practice 9 / the no-prose directive: the frozen-header reconcile receipt is recorded in the commit message, not an in-file HEADER RECONCILE block. D5's intent — a conscious, reviewer-visible reconcile receipt — is preserved via the commit message + git blame; the in-file HEADER RECONCILE block form (integer.dag #3190 precedent) is retired by Practice 9. Closes codex's blocking #3226 finding (D5 ledger row and Practice 9 disagreed until D5 was amended). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * P1-KEYSTONE: fold the coincidence-cite into Practice 9 item 4 claude's exploratory review note on #3226: the Supersession block licenses a one-line `// coincides: <DECISIONS.md ref>` cite, but Practice 9 item 4 only named the concept tag — a reviewer reading item 4 alone could flag a legitimate coincidence cite as prose. Fold the one-line DECISIONS.md cite into item 4 explicitly so the four-class contract is self-contained.

Both Stage and BootstrapStep classified 🟢 GREEN (terminal) with the five patterns (fact-placement / variant-is-data / algebraic / dimensional / parameterized-family) attempted inline, mirroring the witness.dag exemplar.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 T-20: make the bootstrap chain structural — fixed record replaces List<BootstrapStep> Addresses BLOCKING review (bootstrap.dag:190): steps: List<BootstrapStep> admitted reordered/duplicated/missing/extra chains — the seed-once→stage0→stage1→stage2→fixed-point invariant was prose-only (INVARIANTS P2). The chain is fixed by STRUCTURE.md (zero degrees of freedom), so BootstrapPlan is now a FIXED RECORD with four named positional slots whose distinct slot TYPES (CompileStep / FixedPointStep) pin compile-vs-fixedpoint per position. Dissolves the exact node.dag Diff #3162 list-anti-pattern. BootstrapStep coproduct removed (kind is now the slot type, not a variant); Stage coproduct + its Practice-4 ledger retained unchanged (still consumed by the step records — no finding-#1 churn). Within-step Stage wiring is a documented bounded residual (yaml lexeme class; mis-wire = fail-closed interpret-time Diagnostic, the ratified Diff stance — not a type-level illegal state).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 T-24: make the C4 ci.yml claim honest — no fabrication of GHA transport facts Addresses BLOCKING review (ci.dag:146): CiPipeline {jobs,gates} cannot faithfully back a .github/workflows/ci.yml C4 projection — a faithful GHA workflow needs on/runs-on/steps/concurrency/permissions, which the gunbc job/gate DAG deliberately omits, so any CiPipeline->ci.yml emit would fabricate them (INVARIANTS P1/P2). Fix is honesty, not fabrication and not a substrate add: project_ci_yml re-typed to also consume a GHA workflow-schema model (gunbc data fills the schema, never invents it); that schema is named MISSING SUBSTRATE (no v4 counterpart to v3 extdeps/github/actions.dag — a new file = operator-tier, surfaced not added). Committed ci.yml reframed as the explicit interim hand-authored BRIDGE (the affected_set.dag detect-affected-components.sh precedent); C4 checked-projection is an explicit future state gated on the named substrate. The immutable header's Owns/C4-over-CiPipeline over-claim is flagged on the PR for conscious operator confirmation (frozen-header lines NOT worker-edited).

Fixed the "DATA, not a runner" paragraph (now: fixed BootstrapPlan record of named slots) and the Stage ledger pattern-1 (now: every chain step CompileStep/FixedPointStep). The two remaining BootstrapStep mentions are intentional removal-provenance, kept. Comment-only; structural v2-compile gate re-verified (64 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 T-24: defer C4 seam to the ratified single-authority Workflow path (not a worker-minted shape) Addresses BLOCKING (ci.dag:120): the db725fc C4 fix minted a parallel project_ci_yml(CiPipeline, GhaWorkflowSchema) -> YamlValue seam, diverging from the ratified locked T-Workflow-As-Data path project_github_actions(CIWorkflowDag, WorkflowRuntime) -> Workflow (extdeps.github.actions { Workflow } single authority pinned on gunbc.ci CIWorkflowDag; WorkflowRuntime = YamlStatic | BinaryShim; dsl/gunbc/ci_emission.dag) — parallel authority, INVARIANTS P2 (the SELF_HOSTING authority-audit precedent). Fix: the deferred seam now defers to the ratified single-authority Workflow carrier + project_github_actions/WorkflowRuntime seam; ci.yml is the Workflow carrier serialized under YamlStatic (YAML downstream of Workflow), never a parallel CiPipeline -> YamlValue projection. The invented GhaWorkflowSchema/project_ci_yml shape is retracted (kept as provenance, not silently dropped). Missing substrate re-stated as the v4 counterpart of the ratified extdeps.github.actions Workflow carrier + ci_emission.dag seam (operator-tier new file, surfaced not added, not worker-substituted). No-fabrication / interim-bridge / header-tension- surfaced stance preserved. Structural v2-compile gate re-verified (64 modules, 0 diagnostics).

Each of the four positions is now its own payload-less SINGLETON edge-identity type (SeedToStage0 / Stage0ToStage1 / Stage1ToStage2 / FixptStage1Stage2; verified v2 parses `type X = X`). BootstrapPlan is the fixed record of those slots → exactly ONE inhabitant; reorder / duplicate / missing / extra / mis-wire all unconstructible. The Stage coproduct (+ its five-pattern ledger) and BootstrapStep are both removed (stage/edge identity now in the singleton names); no coproduct remains so no Practice-4 ledger applies — this moots the earlier "Stage/BootstrapStep need ledgers" finding by dissolution. The earlier "bounded residual / future-grammar" deferral is retracted as unnecessary (provenance kept, not silently dropped). Structural v2-compile gate re-verified (64 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 T-20: fix singleton step types — empty-record form (constructible); restores green gate bfc8886 used `type X = X` which v2 parses as a type but provides NO usable value constructor (`undefined variable` at the data construction) — that commit broke the structural v2-compile gate (4 errors). Root cause: the earlier probe only DECLARED the singleton, never CONSTRUCTED it. Fixed: the four chain-position singletons are empty records `type X {}` constructed as `X {}` (verified: v2 parses AND constructs this form, 0 diagnostics). Design intent unchanged — BootstrapPlan still has exactly one inhabitant; mis-wiring unconstructible (openai-pro REQUEST_CHANGES + operator P2 resolved structurally). Prose updated (empty-record singleton, not `type X = X`). Structural v2-compile gate re-verified GREEN (64 modules, 1 file emitted, 0 diagnostics, no errors).

Operator-tier actions = briansrls inline BLOCKING (ci.dag:198 C4-fabrication; ci.dag:120 single-authority-seam) + openai-pro. They moved the body to: ci.yml is the ratified Workflow carrier under WorkflowRuntime=YamlStatic via project_github_actions; C4 gated on the missing v4 Workflow substrate (interim hand-authored bridge until then). Reconciled the frozen Owns "emission target" + C4 lines from emit(CiPipeline)/`.dag walks CiPipeline emits YAML` to the single-authority Workflow-carrier projection; added HEADER RECONCILE block. C4 operator-ratified INTENT preserved; only projection mechanism/source corrected, no scope expansion. bootstrap.dag frozen header preserved verbatim (its "ordered step sequence" I/O contract is unchanged by the singleton redesign — correct D5 application).

Updated the para from "SURFACED, worker does NOT edit frozen lines" to "RECONCILED in-PR (D5)" pointing at the HEADER RECONCILE block. Comment hygiene only; no model change.

Fix (both options the finding allowed): (a) store the EXACT primary gate invocation verbatim from .github/workflows/ci.yml ("target/release/v2-compiler compile --source-root src/v4 --output-dir /tmp/v4-stage1 --target dag"); (b) reframe the field as NON-EXECUTABLE documentation data — there is no interpreter (process carrier extdeps/process.dag is T-4.5 scaffold) and a single String cannot carry a GHA job (the live step is a multi-line shell wrapper + a `cargo build` prerequisite). The full faithful step + process spawn stay deferred to extdeps/process.dag (T-4.5) + T-22 (TRACKED SCAFFOLD (3)), explicitly NOT fabricated into the String.

One editorial pass: all BODY occurrences now use "bit-identical" for the stage1==stage2 PROPERTY and `RoundTrips` for the substrate AssertKind (Status note, WHY-PINNED-HASH note, FixptStage1Stage2 type comment; TRACKED SCAFFOLD (2) was already correct). Frozen Owns/Consumes header lines (22/26/76) preserved VERBATIM — a non-blocking hygiene nit is not the operator-tier D5 sanction required to edit frozen header lines; "BitIdentical" there is the property/anchor name, reconcilable with verification.dag's RoundTrips ("self-host bit-identity") once the body is consistent.

Resolved by applying the canonical node.dag Diff #3162 ratification (not a coin-flip — that precedent settles the shape): ANY jobs/gates lists are valid CiPipeline DATA; missing-target/dup-id/cycle are NOT type-level illegal states and there is deliberately NO ci_pipeline_well_formed eager predicate (exactly the #3162 diff_well_formed anti-pattern). The fail-closed WELL-FORMEDNESS boundary is the deferred select_jobs consume fold (apply_diff-analogous all-or-nothing): unresolved/duplicate/cyclic => one fail-closed Diagnostic (Outcome<T>), decidable via visited-set traversal (P4).

Patterns don't auto-extend without the per-instance precondition. Implemented the eager boundary NOW: ci_pipeline_well_formed : CiPipeline -> Outcome<CiPipeline>, covering (1) unique job ids (node.dag all_names_distinct CHECK-enforced precedent), (2) reference resolution (every needs/gate.job resolves to a declared id), (3) acyclicity via Kahn sink-elimination bounded by count(jobs) passes expressed as a fold over the finite jobs list (A2 IMPLICIT termination, INVARIANTS P4) — never an unbounded walk. Any violation = one fail-closed Diagnostic (AmbiguousIntent, no repair-guess). Structural Map-for-ids was INFEASIBLE: v4 Map<K,V> is lookup-only (no key enumeration) so a Map jobs field can't be traversed for the required acyclicity/ref checks; jobs/gates stay List (fold-traversable) per the adjudication's "pick by feasibility" + ACCEPTABLE eager option.

Orthogonal to the bootstrap P2/F1/F2 trilemma (routed, pending still-hawk-102; bootstrap.dag NOT touched). #3213 HELD for audit.

(a) structural per-stage nominal identities FORBIDDEN — do not revert F2 (codex-F2 / Practice-7 stays closed). (b): removed the named consumable `data bootstrap_plan_unchecked: BootstrapPlan`; the BootstrapPlan{...} literal is now inlined as the sole argument to bootstrap_plan_well_formed(p: BootstrapPlan {...}). The ONLY named export consumers can bind is now `bootstrap_plan: Outcome<BootstrapPlan>` (the checked carrier) — the consumable-boundary leak (unchecked raw record had a name to grab) is closed. Mirrors the ci_pipeline expose-only-checked precedent (Lane-B-PASSED). F1 (forward consumes chain) + F2 (single CompileStage) intact; no codex-F2 re-trigger; no shape fork. v2-compiler parses the inlined nested record literal (verified, not shipped blind); structural v2-compile gate GREEN (64 modules, 0 diagnostics). Strict de-prose intact (bootstrap.dag 4.5%, <20%). #3213 HELD for operator re-audit. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: IB-3 T-20+T-24 workflow/bootstrap.dag + workflow/ci.dag — BootstrapPlan * v4 #3213 IB-3: Practice-10 List-op dissolution pass (operator merge gate) std/collection.dag (T-3) declares zero derived List ops -> zero RED (nothing to dissolve into in-PR); every hand-rolled generic List primitive marked YELLOW gated feature: (owner T-3 std/collection.dag, named missing op + dissolve-on-arrival obligation). Kahn composition classified GREEN terminal domain-logic (peer of the well-formed predicates). One terse in-file tag per file (LB-P4-3213 precedent); full LB-P10-3213 ledger in DECISIONS.md Part 7. #3244 disposition vocabulary. Structural v2-compile gate: indexed 67 modules, 0 diagnostics. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: ci.dag expose-only-checked — drop consumable ci_pipeline_unchecked/v2_compile_gate_job (operator REQUEST_CHANGES) Operator (briansrls) BLOCKING: top-level raw ci_pipeline_unchecked: CiPipeline was a second authority beside checked ci_pipeline, bypassable by downstream consumers (P2 single-authority / P3 fail-closed). Fix mirrors the operator-accepted bootstrap (b) expose-only-checked shape: inline the CiPipeline literal (CiJob/CiGate inlined) as the sole arg to ci_pipeline_well_formed; remove the named ci_pipeline_unchecked and v2_compile_gate_job composites so the only consumable pipeline authority is data ci_pipeline: Outcome<CiPipeline>. Header Owns updated. Structural v2-compile gate: indexed 68 modules, 0 diagnostics. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: ci.dag rename ci_kahn_fixpoint fold param counter->job (CODING.md names-describe-the-mapping) Recurring multi-reviewer readability observation (cursor 13938 exploratory): the fold's 2nd callback parameter is the folded `jobs` element, not a counter; `counter` misdescribed the mapping. Renamed to `job` per CODING.md "names describe the mapping". Semantically inert (param remains deliberately unused — the fold is the bounded-iteration driver per LB-P10-3213-KAHN); structural v2-compile gate: indexed 68 modules, 0 diagnostics. Resolves the observation permanently rather than restating "intentional". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: rewrite LB-P4-3213 ledger to #3244 precision (consumer-gate, landed target) CORE ruling (still-hawk-102, Option-1 + #3244): reframe LB-P4-3213 as a valid plan-bound 🟡 with gate kind = consumer: (first meaning-consumer of typed-command shape, deferred-by-brief, gate CLOSED). process.dag::Command is the LANDED migration target (#3209), not the meaning-consumer — future consumer consumes typed Command directly; #3213 does NO migration / NO local CiCommand parse. Anti-#3250: NOT "no change needed". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: bootstrap.dag — split stage compiler-of-record from executor (self-hosting identity) codex BLOCKING + 2 BLOCKING-inline (P1/P2): every CompileStage.via was v2_pipeline, conflating the orchestration executor with the stage compiler-of-record and making the fixpt (stage1==stage2) check vacuous. Fix grounded in load-bearing docs: - STRUCTURE.md:404-405 "Seed used once": v2 produces v4-stage0, then v4 compiles itself; v2 is never in the loop again. - SELF_HOSTING.md §meta-circular: stage0 compiles source->stage1, stage1 compiles source->stage2, assert byte-identical. via -> compiled_by (CODING.md names-describe-the-mapping): seed compiled_by v2_pipeline, self0 by v4_stage0_binary, self1 by v4_stage1_binary. No executor bridge field — STRUCTURE.md is explicit that v2 is seed-once, so no "v2 executes every stage" fact exists; the brief's "v2 is the initial executor" framing contradicted the doc and the doc wins. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: ci.dag consumes bootstrap seed authority — single-authority fix (P2/Practice 5) openai-pro 13971 (BLOCKING, at HEAD 52c207b): ci.dag:52 restated the bootstrap seed action as a raw ShellCommand argv string, a parallel authority for the seed→stage chain that bootstrap.dag BootstrapPlan.seed now canonically owns — drift-prone, violates INVARIANTS P2 single- authority / modeling-discipline Practice 5; the duplication was also untracked debt (review §6). Fix (in-PR, structural model only — not the brief-deferred ci.yml projection / T-22 lane): add typed CiCommand variant BootstrapStageCompile{produces: Symbol}; the v2_compile_src_v4 job now references v4_stage0_binary imported from v4.workflow.bootstrap. A real machine-readable cross-module edge to the bootstrap authority — the raw argv is removed entirely; BootstrapPlan.seed is the sole source of truth. No import cycle (bootstrap does not import ci). Distinct from / orthogonal to CORE-adjudicated LB-P4-3213: that 🟡 is the ShellCommand{String} raw-argv command-SHAPE decomposition, deferred to the consumer lane. This is single-AUTHORITY wiring (an invariant), resolved now. LB-P4-3213 ledger updated to record the resolution. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: IB-3 T-20+T-24 workflow/bootstrap.dag + workflow/ci.dag — BootstrapPlan * v4 #3213: Practice-9 de-prose — in-file rationale → ≤1-line ledger pointers cursor 13986 (NON-BLOCKING, APPROVE_WITH_COMMENTS): ci.dag mid-carrier comment recorded single-authority/P2 rationale as in-file prose (Practice 9 — rationale belongs in DECISIONS.md, already covered by LB-P4-3213). Replace with a one-line `// 🟢 single-authority — DECISIONS.md LB-P4-3213` pointer; strip the same-shape parenthetical from ci.dag Consumes line and tighten bootstrap.dag compiled_by tag for consistency. No semantic change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: Practice-9 — drop bootstrap.dag compiled_by field-prose cursor 13998 (APPROVE_WITH_COMMENTS): the `// stage compiler-of-record` field comment is rationale-on-carrier, not an allowed comment class. The field name + header Scope line already convey the self-hosting identity; structure speaks for itself. No DECISIONS pointer needed (no dedicated ledger entry; header already documents seed-once semantics). No semantic change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: structurally enforce BootstrapStageCompile single-authority at the CI boundary openai-pro 14006 (BLOCKING, manual re-review @ 5d4468d): BootstrapStageCompile{produces:Symbol} took an unconstrained Symbol and ci_pipeline_well_formed never validated it against the canonical BootstrapPlan outputs — the single-authority seam the ledger claims as resolved was prose/convention, not structural enforcement (INVARIANTS P2 / modeling-discipline Practice 5/6). Fix (structural model, in-scope — not the brief-deferred T-22 executable lane): - bootstrap.dag owns bootstrap_stage_output(s: Symbol) -> Bool — the single authority on the canonical stage-output set {v4_stage0_binary, v4_stage1_binary, v4_stage2_binary}. - ci.dag imports it; ci_pipeline_well_formed now consumes the bootstrap authority via ci_all_commands_authority_ok and fail-closed rejects any BootstrapStageCompile.produces outside that set (ci_bootstrap_authority_violation). A dangling payload cannot reach Produced — the invariant is enforced at the substrate boundary, not asserted in prose. - LB-P4-3213 ledger updated: single-authority is now boundary-ENFORCED, not prose. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: ADDRESSED-BY-CONSTRUCTION + plan-bound 🟡 to T-22 (CORE horn (i)) still-hawk-102 ruling (2026-05-18): the BootstrapStageCompile single- authority seam is addressed-by-construction (pure structural predicate; out-of-set produces cannot satisfy the gate — modeled Rejected Outcome, no imperative side-channel; verified in code @6353d695e). Horn (ii) in-PR executable harness REJECTED (T-22-in-#3213 = brief violation). Records the deferred executable demonstration as an explicit plan-bound 🟡 with bilateral binding: - DECISIONS.md LB-T22-3213: arrival (T-22 TestClaim runner) + follow-up (negative TestClaims for the bootstrap-stage rejection family) that dissolves the 🟡. - TASKS.md T-22 scope: same obligation, cross-referencing LB-T22-3213 (neither side vague). - ci.dag in-file one-line tag → LB-T22-3213. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: Practice-9 — single coproduct tag on CiCommand (drop variant-level 🟢) cursor 14020 (APPROVE_WITH_COMMENTS): CiCommand carried two emoji dissolution lines (coproduct-level 🟡 + variant-level 🟢), reading as conflicting dispositions on one type. Rubric wants one required 🟢/🟡/🔴 tag per coproduct; the LB-P4-3213 ledger already carries the single-authority/command-shape nuance. Drop the redundant variant-level 🟢 line; the coproduct-level 🟡 tag + DECISIONS.md ledger stand. No semantic change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: CI bootstrap-authority consumes bootstrap_plan Outcome, fail-closed (P2/P3) Operator BLOCKING inline (#3213 ci.dag:168): bootstrap_stage_output checked static stage-symbol membership {v4_stage0_binary,1,2} instead of consuming bootstrap_plan: Outcome<BootstrapPlan> — so CiPipeline could be Produced even when the canonical bootstrap plan is Rejected, bypassing the fail-closed bootstrap authority (INVARIANTS P2 single-authority / P3 fail-closed). Fix: bootstrap_stage_output now takes Outcome<BootstrapPlan>, matches it — Rejected ⇒ false (fail-closed: CI cannot pass while bootstrap is Rejected), Produced{value: bp} ⇒ produces ∈ {bp.seed/self0/self1 .produces} (validated-plan actual outputs, not a static set). ci.dag imports bootstrap_plan and threads it through ci_command_authority_ok → ci_pipeline_well_formed. The validated bootstrap_plan is now the sole authority. LB-P4-3213 ledger updated (P2/P3, plan-Outcome consumed). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: add mandatory // Ledger: pointer line to load-bearing workflow headers CORE ruling (still-hawk-102 via Lane B): the de-prose-vs-rail fork was FALSE — strict de-prose stands AND one mandatory `// Ledger:` pointer line per load-bearing file (pointer class, not prose). Adds the CORE-specified line after Status: in bootstrap.dag + ci.dag. No body churn; consistent with strict-de-prose (concrete ref pointer, ≤1 line). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: CORE Option B — rescind // Ledger: line, keystone wins (registry doc→files) CORE ruling (still-hawk-102) on the openai-pro 14070 RC vs the modeling-discipline.md:503-531 keystone contradiction: the // Ledger: mandate is RESCINDED — strict de-prose keystone wins (header stays exactly four lines; no see-docs/X pointer in .dag). - bootstrap.dag / ci.dag: remove the // Ledger: line (-1 each). - Registry moves doc→files (Practice 5, top-down): design-pure-bootstrap-zero.md names the two load-bearing workflow files + A3/PROOF-1/STOP-rail + C4; INVARIANTS.md + src/v3/SELF_HOSTING.md add short Practice-5 registry cross-refs. Authority flows doc→files, not per-file upward pointers. Replays swift-ram-178 a94a312 verbatim onto the #3213 branch. Clears openai-pro 14070; consistent with the keystone. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: reconcile to authoritative trimmed spec — drop INVARIANTS.md registry para still-hawk TRIM relay (post-a94a3123f) set the authoritative one-commit spec = NO INVARIANTS.md edit: registry lives only in docs/design-pure-bootstrap-zero.md + src/v3/SELF_HOSTING.md + the .dag // Ledger: strips. 9fda2f0 over-included the INVARIANTS.md para (replayed from the pre-trim a94a312). Drop it to conform; the two authoritative registry homes + .dag strips stand unchanged.
