Refactor tool acquisition: env node provides resources via edges by briansrls · Pull Request #12 · gunb-ai/gunbc

briansrls · 2026-01-31T20:56:11Z

Replace implicit requires_tools mechanism with explicit env node that provides ToolHandles via DAG edges. This makes tool acquisition visible in the graph structure and naturally interceptable in DryRun mode.

Key changes:

Add path field to ToolHandle for resolved binary location
Create EnvOp that upserts tools and emits handles
Add runner_env node to CI graph that provides tool:clippy
Wire env node to clippy_lint via explicit edge
Remove requires_tools field from Node struct
Remove acquire_node_tools/acquire_tool from executor

Resources now flow from owners (env nodes) to consumers via edges, following the capability grant model where ownership is explicit and compile-time visible.

The node_overrides feature was a workaround for mocking non-transport I/O nodes (e.g., CLI tool ops like clippy_lint) in flow tests. With the clippy work in progress, this hack is no longer needed. Removed from: - BoundaryMocks: field, set_node_override(), get_node_override() - MockSpec: NodeOverride struct, node_overrides field, builder method - execute_flat: override check and tool-acquisition skip logic - CI graph mock: clippy_lint node override usage https://claude.ai/code/session_01TsKdtxekzTSGmEws3FwZNN

Replace implicit `requires_tools` mechanism with explicit env node that provides ToolHandles via DAG edges. This makes tool acquisition visible in the graph structure and naturally interceptable in DryRun mode. Key changes: - Add `path` field to ToolHandle for resolved binary location - Create EnvOp that upserts tools and emits handles - Add runner_env node to CI graph that provides tool:clippy - Wire env node to clippy_lint via explicit edge - Remove requires_tools field from Node struct - Remove acquire_node_tools/acquire_tool from executor Resources now flow from owners (env nodes) to consumers via edges, following the capability grant model where ownership is explicit and compile-time visible.

Keep our changes that remove tool acquisition from executor. The main branch had added node override checks before tool acquisition, but since we removed tool acquisition entirely, we take our version. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Ensure DryRun/Simulate doesn't install tools

EnvOp always calls upsert_tool (check/install) during execution, but execute_flat only intercepts transport-executor nodes, so DryRun/Simulate will still run this I/O and can mutate the environment (e.g., installing clippy) even though the comments state it should be mocked. This makes dry runs side‑effectful and can break CI simulations; consider intercepting EnvOp or wiring mock_env_outputs into the DryRun mocks.

    pub fn run(&self, args: &[&str]) -> CliToolOp {
        CliToolOp::run(self.tool, args)
    }


Use ToolHandle’s resolved path when running tools

ToolHandle::run discards the resolved path and returns CliToolOp::run, which later executes via the tool’s run_cmd on PATH. That means the binary actually executed can differ from the acquired handle if PATH changes between the env node and use (or is shadowed), undermining the capability guarantee the handle is meant to provide. Consider binding the path in ToolHandle::run (or using execute_with_handle) so the resolved binary is actually used.

Useful? React with 👍 / 👎.

- Update CliToolOp::Run execution to use ToolHandle from inputs - Add has_mock() method to BoundaryMocks for checking specific mocks - Update docs to reflect env node as I/O boundary - Update tests to count runner_env as a transport/tool node Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Merged claude/investigate-node-overrides-VShEq which removed node_overrides mechanism. Key fixes: - Add consumes_tool_handle() to detect nodes receiving ToolHandle inputs - Update should_intercept to intercept tool consumer nodes in DryRun - Add mock outputs for clippy_lint node (success, stdout, stderr, skip) This ensures nodes consuming ToolHandle (like clippy_lint) are properly intercepted in DryRun mode instead of trying to execute /mock/clippy.

Correctness fixes: 1. HashBuilder now includes path + delimiter + length to prevent boundary collisions (e.g., A="ab",B="c" vs A="a",B="bc") 2. Glob errors propagated instead of silently dropped 3. CI "Fresh" check now verifies output files exist (handles case where manifest restored from cache but files weren't) 4. Manifest load errors return Error, not Missing (corrupted JSON no longer falls back to file existence) 5. Verify mode is strict: missing manifest = fail (can't prove freshness without it) Design issues documented in TODO_hacks for future cleanup: - #6: Duplicate codegen hash logic (fix with gunbc-infra) - #8: GUNBC_EXEC_MODE env var bridge - #9: ResourceHandle forgeable - #10: ManagedResource::compute_key lacks manifest param - #11: SimpleResource silent empty hash - #12: check_state computes keys when entry missing https://claude.ai/code/session_016pyUtRBESrZGpLuwNX7q1c

…pt-5-5-pro reflective) Director synthesis 2026-04-28 surfaced 5 NEW design considerations from gpt-5-5-pro reflective + exploratory analyses against main@74b1e46. Director ask: items (1) and (2) feel critical to land before #1078 promotes since they're foundational to the lens framework declaration. Items (3), (4), (5) named as cascade items. ================================================== (1) Lens<C>: monoid-witness inhabitance ================================================== gpt-5-5-pro Finding #4 (NOVEL): AnalysisDimension<Carrier> at src/v3/std/dimensions.dag:63-78 already duplicates Monoid<Carrier> (dsl/std/algebra.dag:108-112 — op + identity) under different field names. The file documents the monoid law but can't mechanically enforce it because the monoid witness isn't a field. Lens<C>'s prior parallel `compose: (C, C) → C` + `unit: C` fields had the same drift. Fix: replace the parallel pair with structural inhabitance: sequential: Monoid<C> // BindNode composition; structural // inhabitance of Monoid<C> from // dsl/std/algebra.dag:110 Same modeling-discipline move as Q1's Interval<D> consolidation (feedback_epistemic_stacking — every concept attaches to ontological DAG; no parallel-rep). Monoid law (associativity + identity) becomes structurally enforceable; downstream consumers project from sequential.op / sequential.identity rather than reading two parallel fields. Future algebraic refinements (CommutativeMonoid for unordered sequential; Group for invertible composition) attach by extending the parent. `branch` stays NOT a monoid op — exclusive choice doesn't require an identity (no "no-op branch"). It's a standalone (C, C) → C with max/join semantics. User instances may declare branch: Monoid<C> for their own use case. 3 worked instances updated to the inhabitance shape: - Complexity: sequential = Monoid<SymbolicCost> with op = work-additive + span-additive + class-max; identity = zero-cost - Tenant-flow: sequential = Monoid<CapSet> with op = set union; identity = {} (note: actually CommutativeMonoid since union is commutative; framework only requires Monoid) - IFC: sequential = Monoid<SecurityLabel> with op = lattice join; identity = Public (lattice bottom; refinement is BoundedSemilattice via BoundedLattice<SecurityLabel>) ================================================== (2) SymbolicCost algebra witness ================================================== gpt-5-5-pro Finding #6 (NOVEL): SymbolicCost has de-facto semiring/ lattice behavior but no declared algebra witness. sequential ≈ additive monoid, iterate ≈ multiplication, branch ≈ lattice meet/order. Without explicit witnesses, complexity/cost consumers can't compose generically. Fix: declare the algebra explicitly in design-lens-framework.md Instance 1 (cost basis): inhabits SymbolicCost : Monoid<SymbolicCost> // sequential inhabits SymbolicCost : JoinSemilattice<SymbolicCost> // branch inhabits BigOClass : BoundedLattice<BigOClass> // class The lens framework reads these via Dag::declarations(); the Lens< SymbolicCost> instance projects from the inhabitance witnesses rather than free-standing functions. ================================================== (3) MethodContract consolidation — cascade item ================================================== gpt-5-5-pro Finding #11 (NOVEL): runtime.dag declares MethodTranslation { dag_method, rust_template } AND emit.dag declares SimpleMethodSpec { method_name, template, wraps_result } — same fact, different schemas, ALREADY-DRIFTED templates: Rust count: runtime "{recv}.len()" vs emit "({recv}.len() as i64)" placeholders: {arg0} (runtime) vs {arg} (emit) Pattern across Rust/Python/Go = parallel-rep x 3. Fix: named as substrate-completion sub-lane in design-emission-model.md §"Cascade across upstream docs" — single MethodContract { dag_method, runtime_template, emit_template, wraps_result, placeholder_convention } per-target row in T-Ground-LanguageSpec scope. Method-translation IS substrate; two parallel authorities violates engine-retraction discipline directly. ================================================== (4) Bool inhabits BooleanAlgebra<Bool> dissolution — cascade item ================================================== gpt-5-5-pro Finding #1+#2: src/v3/compiler/src/bootstrap.rs:91-174 has patch_kernel_bool_boolean_algebra_inhabits because v2 compiler surface doesn't accept `type … inhabits … =` in dsl/. Comment names dissolution explicitly. Fix: named as cascade target in design-emission-model.md §"Cascade across upstream docs" — when v2 surface lands, declare `type Bool inhabits BooleanAlgebra<Bool> = True | False`; patch + operator-resolver fallback retire mechanically. Lane home: T-Ground- Coercion-Fold (substrate-completion) or future T-Bridge-Retirement. ================================================== (5) include_str! retirement — cascade item ================================================== gpt-5-5-pro Finding #12: src/v3/compiler/src/pipeline_authority.rs: 135-178 does include_str!("../pipeline.dag") then line-parses source text to extract stage names — same fact lives as PipelineStageBinding data AND as compile-body source-text lines. Fix: named as R3 T-Bridge-Retirement sub-lane in design-emission-model §"Cascade across upstream docs" — unified ledger of include_str! side-channels across the codebase; each instance retires when its consumer can read the structured authority directly. ================================================== Items (6)-(8) — Director-owned post-#1078 work ================================================== These are tracked in PR thread; not in this commit: 6.

…ition); add STOP #12 for toolchain/edition delta from pin

openai-pro reviewer (PR #1783, on commit 0d1bac6) flagged two self-contradictions in dispatch authority: 1. **Manager routing R2 vs R3**: line 7 said "R2 Grounding Manager" but line 252 + cross-program signal use "R3 Grounding Manager (#1745)". Future workers would have conflicting STOP-escalation targets. Resolved: line 7 now reads "R3 Grounding Manager (#1745)" with explicit absorption note for the R2→R3 rename. All routing now targets #1745 consistently. 2. **Allocator-axis single-authority conflict**: line 85 said "every collection carrier carries hidden generic parameters (allocator A, hasher S) that the brief MUST surface" but line 89 + STOP #11 say allocator is unstable on 1.86 stable / out of scope for Phase 1. Resolved: line 85 reframed as "stable parameters at the pinned 1.86.0 toolchain" — hasher is in scope (stable), allocator is held under STOP #11/#12 (unstable). Authoring an allocator-axis under the stable pin is itself a P1 violation (unstable spec fact under stable pin). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Requiring exactly one base_trait dropped auto-traits-only trait-object facts under P1/extdeps fidelity. - §A line 68: base_trait: TraitRef -> Option<TraitRef>; "exactly one" -> "at most one (zero valid for auto-traits-only objects)". - §A line 71: dyn-compatibility check applies only when Some(_); None case vacuously satisfied (auto traits are always dyn-compatible). - §C line 122: TraitObjectPrimitive mirrors the Optional shape + vacuous-satisfaction note.

Downstream grounding lost callable/admissibility facts under P1/P2. Added derivation receipt sub-bullet on the FunctionItemPrimitive row: - Unconditional Copy/Clone/Send/Sync (zero-sized, no captures). - Conditional Fn/FnMut/FnOnce derived from item_decl qualifiers: inhabits all three iff unsafe = false AND abi = Rust AND target_feature = None; otherwise blocked. - Trait-inhabitance is DERIVED not stored (P2; mirrors ClosurePrimitive derived-not-stored rule for the same trait family).

Other new variants (FloatPrimitive, TextualPrimitive, NeverPrimitive, CompoundPrimitive, FunctionPointerPrimitive, ClosurePrimitive, ReferencePrimitive, TraitObjectPrimitive, ImplTraitArgPrimitive, ImplTraitReturnPrimitive) dropped the fact under P2 facts-flow. Added "Per-variant is_copy derivation receipt" section after the variant list with structural derivation for every new variant, citing Rust Reference §"Copy" + §"Special types and traits" + §"Auto traits" (pinned to 1.86.0). is_copy is DERIVED not stored on every variant, mirroring the lends_to_future/fn_traits discipline in ClosurePrimitive and the FunctionItemPrimitive precedent. Companion is_clone/is_send/ is_sync facts follow the same per-variant rule. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(brief): FunctionPointerPrimitive — FnSignature shape + variadic + HRTB axes Reviewer (PR #1783 inline at line 120) correct: FunctionPointerPrimitive delegated to an undefined FnSignature and only named unsafe/abi, leaving variadic extern signatures (e.g., unsafe extern "C" fn(*const u8, ...) -> i32) and higher-ranked binders (e.g., for<'a> fn(&'a T) -> &'a T) without a substrate home under P1/P2. Extended the row with three additions: 1. FnSignature shape pinned: { params: List<Param>, return: ReturnType } per Rust Reference §"Function pointer types"; ReturnType distinguishes Never from () (the -> ! divergent return is structurally distinct). Same type shared by FunctionItem/Closure signatures (not undefined). 2. variadic: Bool axis with cross-axis constraint (variadic = true ⇒ abi ≠ Rust per Rust Reference §"Variadic functions"; emit-time error otherwise). Required to round-trip extern variadic signatures. 3. hrtb: List<LifetimeParam> axis carrying the for<'a, ...> binder list. HRTB lifetimes introduce a fresh binder, structurally distinct from outer-scope lifetimes — for<'a> fn(&'a T) and fn(&'static T) are distinct types and the row MUST distinguish them or P1 fidelity is lost.

This was a substrate-correctness defect — would mark &uniq-capturing closures Copy contrary to Rust's own closure trait rules. Two fixes in one commit: 1. ClosurePrimitive is_copy rule (line 154): "mode = SharedBorrow" only; both MutableBorrow AND UniqueImmutableBorrow now block Copy. Authority pinned: https://doc.rust-lang.org/1.86.0/reference/types/closure.html. 2. Acceptance test #9 added: behavior-driven coverage of derived is_copy + closure-trait correctness with six closure cases (no captures, SharedBorrow, MutableBorrow, UniqueImmutableBorrow negative, ByValue Copy, ByValue non-Copy) + one function-item case (unsafe/extern qualifier blocks Fn-tower). Catches drift in the per-variant derivation rules before walker rows land. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: proud-lark-674 * fix(brief): RPIT capture matrix — item_kind-scoped + per-abstract-type openai-pro reviewer (PR #1783, on commit 251cabb, REQUEST_CHANGES) correct on two RPIT capture-rule defects per Rust Reference §"Impl Trait" → "Capturing": 1. **Default capture: edition rule scoped to item_kind** (line 136). Old text said "Rust 2015/2018/2021 captures lifetimes only if named in trait_bounds" (edition-only rule). The pre-2024 lifetime exception applies ONLY to free fns + inherent associated fns/methods. Trait methods + trait-impl methods capture ALL in-scope generics (type, const, AND lifetime) regardless of edition. Following the old rule would under-capture lifetimes on trait-method RPIT rows (P1 violation). Default-capture is now derived from (edition, item_kind, trait_bounds) jointly, with explicit item_kind-by-item_kind enumeration. 2. **use<> legality: per-abstract-type, NOT cross-sibling** (line 139). Old text said use<> must include lifetimes from "other return bounds in the same function signature" (cross-sibling). Rust Reference rule is per abstract return type: each return's use<> only needs lifetimes from its OWN bounds. Cross-sibling enforcement authors parallel/fictional authority and rejects legal Rust signatures (P1/P2). Removed other_return_bounds from the input list (was 7 inputs, now 6); rule reframed as "lifetimes appearing in THIS abstract type's own trait_bounds". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(brief): §A RPIT capture summary defers to §C item_kind matrix openai-pro reviewer (PR #1783, on commit 7f32aec, REQUEST_CHANGES) correct: when fixing §C in commit 7f32aec, I left §A line 74 with the old edition-only lifetime-capture rule. §A and §C now disagreed on the same RPIT lifetime-capture fact — duplicate authority for a substrate fact (P1/P2 violation). Resolved at §A line 74: - "Edition only governs lifetime default-capture" → "Default capture is item_kind-dependent, NOT edition-only". - Pre-2024 lifetime exception explicitly scoped to free fns + inherent associated fns/methods only; trait methods + trait-impl methods capture ALL in-scope generics regardless of edition. - §A explicitly defers to §C for the authoritative item_kind-by- item_kind matrix. - use<> constraint #2 also synced to §C: per-abstract-type lifetime rule, NOT cross-sibling. Single authority restored: §C is the source of truth, §A is a summary that points at it.

Resolved by adding an explicit "Authority-file rename pending" note: file rename is Director-routed scope (out of this lane); citations to r2-grounding-manager.md:NN reference the live HEAD path verbatim and remain valid until rename lands; STOP routing already targets #1745. Treats the two as a single coordinated authority, not a contradiction. 2. **ReturnType = Type | Never duplicated NeverPrimitive** (line 94): FnSignature gave `!` a second representation alongside the existing NeverPrimitive row (P2 single-authority violation). Resolved: ReturnType reduced to `Type`. The `-> !` divergent return is a Type whose row is NeverPrimitive. `-> ()` is a Type whose row is CompoundPrimitive { kind: Tuple, elements: [] }. 3. **variadic + abi cross-axis precondition violated illegal-states discipline** (line 95): variadic: Bool + abi: AbiTag let variadic=true ∧ abi=Rust be representable, then relied on validation. Resolved: variadic moved INSIDE the AbiKind sum's Extern arm. AbiKind = Rust | Extern { abi: ExternAbi, variadic: Bool }. The illegal state is now un-representable at the type level (P2 / API-level enforcement, not runtime validation).

Per MODELING.md M9 (DFS the concept DAG), each row should attach to the existing concept it refines. Fixed: Vec<T> now opens with "Inhabits List<T> = FreeMonoid<T>" per the M9 substrate parent (consistent with String inhabiting FreeMonoid<Char>). Refinement axes follow as narrowing facts. 2. **Lending derivation reads (mode, body_use) jointly** (line 127): prior rule classified all UniqueImmutableBorrow captures as non-lending. But a &uniq T capture is itself a borrow of an &mut T referent — if the future MUTATES through the referent (body_use ∈ {mutate, consume}), the underlying mutable place is aliased across calls, which is lending. Fixed: lending rule now reads BOTH mode and body_use per capture. Three lending triggers: - mode = MutableBorrow (any body_use) - mode = ByValue (consumed by future) - mode = UniqueImmutableBorrow AND body_use ∈ {mutate, consume} Non-lending: SharedBorrow (any body_use) or UniqueImmutableBorrow with body_use = read only, OR deref-projection exception.

Fixed: claim narrowed to "Validates PR-F's Q1 lock only"; Q2 explicitly noted as NOT exercised by this slice (separate slice required).

Codex correctly flagged that both projection reports were calling `evaluate_body(...

Route the compare projection through `RightFirst` so the two projections are genuinely distinct evaluator runs.

* R3 gate #13: tc3 pattern a second mover executable Bounded-runner Pattern-A second-mover bridge analogous to gate-#12 TC2 Church-Rosser: the test runner detects the fixture-local `tc3_evaluation_step_baseline_dimension_report` / `tc3_evaluation_step_compare_dimension_report` role pair, evaluates the embedded `succ(succ(0))` top-level value bind under `evaluate_body`, and materializes two `DimensionReport::DimensionOk` projection reports with distinct `dimension_name` keys. Equivalence under `BinaryDimensionReportEquals` (same `Value`, distinct projection-name keys, empty witness lists) yields `Pass` for the §1.8 gate-#13 canonical claim `tc3_pattern_a_second_mover_executable`. Single forward dissolution trigger: D4 eval-step / bounded-step producer surface + G1.a static-lens-fold producer-surface-wiring per `docs/briefs/r3-evaluator-tc3-d4-eval-step-producer-worker.md` — when those producers land on `origin/main`, this runner arm migrates to live producer-emitted `DimensionReport<Dag>` values (replacing the proxy `composed` clone + empty witness lists) without changing fixture or claim name. §1.8 ledger row #13 flipped to CONSUMER_LANDED + PASSING; integration test flips from shape-valid `NotYetImplemented` to `Pass` without fixture edits.

Trio convergence (algebra + Phase 1.5 PR + Phase 3 emission + parity) is the *gating precondition* that authorizes cut-over dispatch, not the authority flip itself. - dsl/ctrl/README.md §"Authority": rewritten to name cut-over as the single trigger; trio as gating precondition. - worker brief module-header receipt: STAGED → AUTHORITY trigger named as the cut-over event; trio reframed as the precondition list that authorizes cut-over dispatch. - Mgr brief §"Wave-1-trio checkpoint": Wave-1-trio convergence qualified as "gating precondition for Phase 4 cut-over dispatch, NOT itself the STAGED→AUTHORITY flip."

Parity-proof is the precondition for cut-over dispatch; not sufficient alone. No overlap window between substrates. #2 (inline BLOCKING / worker brief :77): AttachedUrlContainer widened to include ReviewCommentBody without matching source-fact import (extract_attached_urls only takes PullRequest + List<IssueComment> + List<PullReview>; no List<ReviewComment>). Resolved by dropping ReviewCommentBody from this worker's scope: AttachedUrlContainer = PrBody | IssueCommentBody | PullReviewBody, one-to-one with the imported source-fact set. ReviewCommentBody gates on a follow-up Phase 1.5 PR that adds ListReviewComments to imports. Until then no AttachedUrl value can claim a ReviewComment source — INVARIANTS P2 single-authority holds.

dag/test/claim/effect_expectation_probe_test.dag matched the `_test.dag` suffix discovery enrolls on (cli_run.rs:1746) while containing zero `test fn`. That is "enrolled, zero executions" — the coverage-by-illusion the Phase-0 admission invariant exists to red — introduced in the same session that removed a vacuous witness for being unable to fail. Keeping it would have been worse than deleting it. Its arms cannot discriminate in-language: all three corners of the seam return the same Bool, and the observable that separates them is whether the Failed line renders. Dressing that up as a `test fn` over the verdicts would have produced exactly the shape ffc1eec's own commit message criticises. The three-corner receipt is not lost — it is recorded verbatim in ffc1eec, proven by execution. What is missing is an AUTOMATED consumer that fails if the threading regresses, and that is now tracked (task #12) with the seed's own precedent named: dispatch_shell_wiring_refuses_oversized_argv exists because predicate-only tests do not exercise that call path, and the same gap applies here.

CI red on b2411f0, batch 3, and the failure is mine: both wall arms hit "hermetic mode: no mock_response for operation Run — refusing to fabricate Unit". The wall spawns claim_batch as a CHILD PROCESS to read a passing corpus's own stderr, so it is Wet by construction, and I let filename convention enroll it into the hermetic discovery corpus. The refusal is correct and worth stating rather than routing around: a mocked child emits no real observation stream, so a hermetic version of this witness could only ever pass VACUOUSLY — which is precisely the defect class the wall was built to end. ci_layer_roots' install_media_real_execution_wet_note already described this exact failure ("no mock_response for operation Dir"), so the lane and its idiom existed; I simply did not declare into it. Fixed the way the corpus already does it: a WitnessExclusionRow carves the file out of per-PR hermetic discovery with a typed reason, and two bin_wet rows enroll both arms on the wet lane beside the other real-execution witnesses. Not a mock, not a skip — the same mechanism, declared. The dissolve_on says no dissolution is expected, deliberately. Reading a real run's rendered stream is the irreducible content of this check, so it stays Wet while the glyph wall exists; it deletes only if a structural lens over the effect graph supersedes it (task #15). I FLAGGED THIS ONE TURN EARLY AND MISREAD IT. I wrote that the wall's cost was unmeasured and it "may need enrolling on the bin-wet lane" — right lane, wrong reason. It is not a budget question at all: a Wet witness cannot live in hermetic discovery at any cost, because the mode refuses it. Naming a risk is not the same as classifying it, and I shipped on the weaker read. Verified: ci_floor_plan_witnesses green, witness_exclusion_frontier_ reconciliation_holds green (the exclusion is reconciled, not orphaned), and both wall arms still green locally. ALSO CONFIRMED THIS TURN, by perturbation: re-hardwiring dispatch_shell's binding back to ExpectSuccess and rebuilding all three bins REDS the wall. So the wall is already an executing consumer for the threading — task #12's core regression case is covered, and a separate Rust wiring test would have been redundant. Its remaining residue is narrower than filed: the ExpectFailure x ObservedSuccess divergence corner has no live site, and the OutcomeIsData-consumer-disappears case still needs one.

…e stages at arm time Step 0 of the review disposition, plus the two findings fixable without the run_stage extraction. The remaining findings are named, not silently carried. REBASE, and the conflict was load-bearing exactly as predicted. #7467 added floor_component_receipt_ok to the walk verdict; this branch had replaced that composition with ordinary_failed || on_success_failed. Resolved by folding the component receipt INTO ordinary_failed, so a component-receipt construction or write failure is an ordinary-floor failure that blocks every success stage — dropping it would have reopened the very ordering defect this branch exists to close. The test fixture also gained #7467's new BatchRecord label/selection_tag fields. THE CARRIER NOW DESCRIBES THE EXECUTOR IT HAS, not the one it wants. The note claimed members within a stage run concurrently and that each stage writes its receipt before the next begins; neither is true today — members run serially and one aggregate receipt is written after the whole sequence. A carrier promising a guarantee its executor does not provide is the defect this type exists to end, and I had reintroduced it. The note now states the barrier that IS real (stage N completes before N+1; a failed stage prevents every later one) and names three gaps: serial members, stages bypassing the ordinary unit-lane partition and therefore governor admission and clamps, and the aggregate receipt. The repair — extracting the ordinary batch machinery into a reusable run_stage so both populations share one executor — is named on the carrier as the next step. ARM-TIME STAGE VALIDATION. Success-stage admissibility is checked immediately after the plan parses, BEFORE the governor arms and before any ordinary batch runs: a plan-shape error is knowable at parse time, and discovering it after a 20-30 minute floor spends the whole walk to report something the parse already had. Refuses discovery runnables (no defined green-only meaning), empty entry/function, and heavy-whole-tree-resolve claims (which would bypass governor admission through the weaker route). ONE HONEST NARROWING: I first wrote the validator against profile.spawns_host_compiler and profile.memory — fields the Rust Runnable does not carry. Only use_walk_memo (the parsed form of heavy_whole_tree_resolve) and execution_mode survive parsing, so the validator walls the heavy-resolve case and says so; walling the other two requires retaining them on Runnable, which lands with the run_stage extraction. The wall is narrower than intended and the code says which part is missing rather than implying full coverage. VERIFIED: cargo test 37/37 (including both floor-finalization arms against the rebased BatchRecord); the WalkPlan parser RED still refuses a bare-list plan post-rebase; generated artifacts regenerate clean; fmt clean. STILL OWED, from the review and unstarted: run_stage extraction with real intra-stage concurrency and per-stage receipts; finalization policy carried by WalkPlan rather than selected by plan-function name; schedule-lens projections that see the stage population; the discriminating executor control set; then the admission occupants and the task #12 deletion.

…— see known gaps) (#7470) * WalkPlan: give walk plans an on-success stage population, parsed strictly Foundation commit of the success-stages redesign (operator design ruling 2026-07-30). This lands the carrier, the strict parser, the renames, and sequential fail-fast stage execution in the executor. Every plan declares on_success_stages: [] today, so runtime behavior is unchanged until the merge-admission migration populates the floor plan's stages in a follow-up commit on this branch. THE CARRIER. std.realization_schedule gains type WalkPlan { batches: List<List<Runnable>> on_success_stages: List<List<Runnable>> } Two populations with different ordering laws, and the type says so where a bare List<List<Runnable>> could not: batches are the ordinary floor under FloorBatchStopPolicy; on_success_stages run only after the ordinary floor completed AND its receipts wrote, each stage a barrier, always fail-fast between stages — FullLedger is an ordinary-floor policy and never applies between stages. The carrier note records BOTH prior defects: the trailing-batch fail-open, and its sibling — members WITHIN a stage run concurrently, so anything sequential must be ONE claim whose body sequences its steps (the first repair draft re-created exactly that bug and the note names it so the next author does not). THE RENAMES, because a function whose value now carries postcondition stages must not keep a name that says it returns only batches: gunbc_ci_floor_batches -> gunbc_ci_floor_plan gunbc_ci_regen_floor_batches -> gunbc_ci_regen_floor_plan gunbc_ci_plan_artifact_batches -> gunbc_ci_plan_artifact_plan gunbc_falsifier_batches -> gunbc_falsifier_plan The four argv/step consumers followed automatically because they derive from the floor_plan_function / plan_artifact_plan_function / regen_floor_plan_function / falsifier_plan_function constants — the constants are the single naming authority and were renamed with the functions; ci.yml and falsifier.yml regenerate with the new names at all three invocation sites. The internal batch builders survive as *_ordinary_batches, which the structural witnesses now target. The budget_red_control fixture renames with the floor fn it impersonates (the clamp arms by name). Executor string keys (clamp gate, falsifier budget flag, eager compile-clean install, arm-time refusal roster) renamed in the same motion. THE PARSER is one and strict. walk_plan_from_plan requires BOTH fields; a plan with no postconditions declares an empty list, never omits the field, and there is deliberately NO fallback from a failed record parse to a bare-list reading — that fallback would run a malformed plan with its success stages silently dropped, the silent-widen arm section 5 forbids. STAGE EXECUTION in run_walk: gated on the whole ordinary floor contract this process owns — batch verdicts AND every receipt write — not just any_failed. Members execute serially in-process via run_memo_shared_claims with a stage-local memo, so an entry shared by stages resolves once and is reused; serial execution provides more order than the contract promises, which is safe, while the contract itself promises none. A non-claim runnable in a stage is a typed refusal, never a widen. Stage materialization is structurally NOT folded into the floor materialization receipt: stage memo contexts drop after it is written. A new receipt class, target/floor-on-success-receipt.txt, records declared/run counts, per-stage verdicts, and on_success_resolves_total — separate from the ordinary resolve receipt BY LIFECYCLE, so ci_floor_declared_resolve_count measures exactly the population it always did. On a red ordinary floor the receipt still writes, loudly, with skipped=ordinary_floor_failed and zero stages run — a typed diagnostic, never an admission artifact. VERIFIED BY EXECUTION: RED a bare-list plan fn refuses: "malformed plan value (gunbc_ci_floor_ordinary_batches): WalkPlan missing field `batches`", exit 1 — no fallback. (This control also caught a missed internal call site at ci_floor_plan.dag:1360.) GREEN gunbc_ci_floor_plan parses to the same 5 batches, then this container's pre-existing FloorBudgetBelowMinimumFootprint fail-fast — which itself proves the parse ran first. ci_floor_plan_witness_test 14/14 · ci_spec_witness_test 27/27 · falsifier_workflow_witness_test 11/11 · gunbc_invoke_witness_test 7/7 · pr_native_batch_test 2/2 · realization_schedule_witness 4/4. Generated artifacts regenerate; cargo fmt --check clean; claim_executor and gunbc build clean. (Workspace-wide cargo build fails in v1-stage0-std-core with 7 pre-existing errors, present on clean origin/main with this change stashed; CI builds named bins only.) REMAINING ON THIS BRANCH, per the settled design: executor-level floor finalization (resolve law + materialization disclosure in-process, the two GitHub gate steps deleted), the tools.merge_admission entry (capture_tested_subject as the first ordinary batch, stamp_tested_floor, refresh_target_and_gate), attempt-scoped receipt schema v2, the task #12 dead-emitter deletion, timeout derivation as the two-budget sum, and the operator's witness list including the stage-barrier latch test. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7LfCpidMuDjV3FxYUHv1K * Floor finalization moves in-executor; the two receipt-gate steps delete Phase 1 of the success-stages redesign (operator ruling 2026-07-30): the resolve-count law and the materialization disclosure law now run INSIDE claim_executor as ordinary-floor finalization, after the receipts write and before any on-success stage. The old shape ran them as two GitHub shell steps AFTER the floor step, so a receipt-law violation could red the job after admission had already stamped — the can-red-after-admission hole. In here, a violation is an ordinary-floor failure and blocks every on-success stage by construction. MECHANISM. The floor plan projects its law into its own closure: gunbc_ci_floor_declared_resolve_count in ci_floor_plan.dag reads the ci_materialization authority (single authority; the projection is a read, not a second declaration). The executor reads it fail-closed at arm time for the floor plan only — a floor-named plan whose law cannot be read refuses the run rather than walking without its contract — and validates: law 1: resolves_total (recomputed from batch_records by the SAME nonzero-resolve_nanos rule the receipt writer uses, never re-parsed from the file we just wrote) equals the declared count law 2: the materialization receipt exists, keyed/unkeyed/duplicated parse, and keyed_calls is nonzero Violations are typed FLOOR-FINALIZATION-REFUSED lines, counted into failure_details. Regen, falsifier, and plan-artifact declare no finalization and are byte-unchanged in behavior. DELETED, NOT UNWIRED: both gate scripts and their Scaffold rows in ci_materialization, both step constructors in ci_workflow, and the two aux terms in the ci job backstop (100 -> 90, still the exact step-sum + prelude). A surviving script would be a second representation of the floor-completion rule whose still-green tests could mask a live-path regression — the exact shape that hid the lost admission fetch. The receipt FILES keep writing; they are observability, and only the shell re-validation of them is gone. ci_spec_witness_test gains the negative witness that both step names are absent from the emitted workflow. THE FIXTURE follows the name it impersonates: budget_red_control_plan declares the law (1 — it runs exactly one single-claim batch) because the floor name now arms finalization as well as the clamp; before that row landed, running it WITHOUT the law was the executable RED of the fail-closed read. ONE MORE TRANSCRIPTION DELETED, caught by this change redding it: ci_job_backstop_equals_one_hundred_minutes mirrored the derived step-sum as a literal 100, so this correct change reported as a failure and the reviewer move would have been editing the number to 90 — the same class as the roadmap 63-declared pin, deleted under the same ruling. The magnitude-independent invariants stay: exact step-sum + prelude (its conscious double-entry copy updated to the four remaining aux terms) and the dropped selection-control term. VERIFIED BY EXECUTION: projection reads 1 from the plan closure (gunbc run) RED fixture without the law: "gunbc_ci_floor_declared_resolve_count unavailable (fail-closed)", exit 1, before any batch walks unit arms (cargo test, 2 new): count mismatch refuses in BOTH directions; matching count leaves exactly the missing-receipt refusal when no materialization file exists — absence never passes ci_spec_witness_test 28/28 · ci_workflow_witness_holds PASS ci.yml regenerates: both gate steps gone, ci job timeout 100 -> 90 NOT PROVEN HERE: the full-floor green path through finalization — the fixture walk now proceeds past the arm into the eager whole-tree compile-clean install (~72min class) and was killed at a local 10-minute cap, and the real floor fail-fasts on this container's memory. Owed to the fleet run with the rest of the merge bar. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7LfCpidMuDjV3FxYUHv1K * Attempt-scoped admission carrier: receipt v2, TestedSubject, WrongAttempt Phase 3 slice of the success-stages redesign (operator ruling 2026-07-30): the pure carrier for attempt-scoped merge admission, landed add-replacement beside the live v1 format. No consumer migrates yet — the wet entry, the plan wiring, and the v1/emitter-web deletion follow on this branch — so runtime behavior is unchanged; this slice is the vocabulary the migration will speak, proven hermetically before anything wet depends on it. THE CARRIER. MergeAdmissionReceiptV2 carries the walk-attempt identity IN THE PAYLOAD, not just the path: a misrouted read must fail on content too. TestedSubject {attempt_id, head_sha, base_ref, base_tree_hash} is the subject the floor tested, captured pre-floor and bound into the receipt by the stamp — the stamp must never re-read HEAD or re-observe the target at stamp time, because main can advance during a tens-of-minutes floor and a post-floor observation would claim the floor tested a tree it never saw. THE VERDICT gains MergeDeniedWrongAttempt, checked FIRST: a receipt from another attempt is neither stale nor fresh — it is not the subject, and asking whether a foreign receipt's base is current answers a question about the wrong run. Growing the coproduct forced every exhaustive match to take a position (non-fold residue, no wildcards): the gate's verdict_reason, would_block, and the enforcement/actuator witnesses each gained the arm consciously, and the compiler's exhaustiveness refusal located the one site the sweep missed (receipt_is_admissible) — the coproduct growth is complete by construction, not by grep. ATTEMPT IDENTITY composes from GITHUB_RUN_ID + RUN_ATTEMPT + JOB, pure composition here, env observation deferred to the wet entry. Every part must be nonempty or the composition refuses — never a silent 'local' constant, which would make every non-GitHub run one attempt and leave the wrong-attempt refusal unreachable off CI (the unreachable-arm shape §5 forbids). Non-GitHub execution supplies GUNBC_WALK_ATTEMPT_ID explicitly, same nonempty law. WIRES are self-identifying (schema tag line 1), unlike positional v1: a v1 wire fed to the v2 parser refuses on the tag rather than mis-binding fields by position, and the two v2 wire kinds refuse each other. Paths are attempt-scoped: .gunbc/merge-admission/<attempt-id>/{tested-subject, floor-receipt}.wire. VERIFIED BY EXECUTION — 13/13 new hermetic witnesses, including the ordering proof (a receipt that is simultaneously foreign, Failure, stale- base, AND stale-roster classifies WrongAttempt — precedence, not coincidence), both cross-parser refusals, both roundtrips, the nonempty refusals, and path distinctness across attempts. Existing admission witnesses regress clean: producer 15/15, enforcement 13/13, actuator 8/8. Generated artifacts unchanged (model + tests only). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7LfCpidMuDjV3FxYUHv1K * Carry finalization policy in WalkPlan; regenerate the stale stage0 seed Two halves: review finding 4, and the fix for the regen red CI just reported on this branch. WALKFINALIZATION IN THE CARRIER. The finalization policy was selected by plan-function name — `if plan_function == "gunbc_ci_floor_plan" read the law from the closure` — which is the same hidden seed-roster convention the WalkPlan carrier was built to remove, reintroduced in the same PR. The RED fixture made the coupling visible: it had to impersonate the production plan name and then define a projection fn because that name silently enrolled the contract. The policy is now a FIELD: type WalkFinalization = NoWalkFinalization | FloorFinalization { declared_resolve_count: Int require_materialization_disclosure: Bool } type WalkPlan { batches, finalization, on_success_stages } Every plan declares it explicitly — the floor carries its law, regen / plan-artifact / falsifier say NoWalkFinalization, never omission. The strict parser requires the field, so a floor plan without its law is now UNWRITABLE rather than discovered missing at arm time — the fail-closed arm-time read this replaces is deleted along with the projection fn and the fixture's name-impersonated law. Schedule lenses and plan artifacts can now see the policy, because it is part of the parsed value. THE REGEN RED, diagnosed from the job log: regen_verify_gate_passes returned false on this branch's previous head because the WalkPlan carrier change touched dag/std/realization_schedule.dag, which is in v1's regen input closure, and the committed stage0 seed was stale against it. regen_stage0 confirms the diagnosis exactly: of 108 written files, precisely ONE differs — std_realization_schedule.rs, the emitted Rust of the carrier — now regenerated against the current tree (including WalkFinalization, so one seed covers both changes) and proven byte-stable on a second regen run. VERIFIED: cargo build clean; the two floor-finalization unit arms pass against the field-carried struct; gunbc-eval of gunbc_ci_floor_plan shows the plan value carrying FloorFinalization { declared_resolve_count 1, require_materialization_disclosure true }; generated artifacts regenerate clean; fmt clean. Local executor parse probes of the fixture and regen plans were killed by this container's timeout during the multi-minute prelude, before reaching the parse line — inconclusive, not failing; the pushed run is the parse evidence.
