feat(ci): gunbc_ci affected gate selection from CIWorkflowDag + diff (#103) by briansrls · Pull Request #2798 · gunb-ai/gunbc

briansrls · 2026-05-12T21:47:54Z

SG-0 hand-path delta: +1

SG-0 pairing: (c) dispatch tracked via docs/briefs/r3-wave1-s6-slice7-affected-set-impl-worker.md for remainder of gate #103 (BinaryShim + lens integration); this PR adds one EXPECTED_HAND_AUTHORED_NON_TEST row only.

Auto-opened by session-dashboard for session swift-wren-365.
Pushing to session/swift-wren-365 advances this PR.

Summary

Adds v3_compiler::gunbc_ci: pure affected gate selection over a structural CIWorkflowDag mirror (CiWorkflowDagInput + prerequisite edges) and a gate-id diff (CiWorkflowDiff). Selection expands the touched seed by symmetric CIGateEdge closure (undirected adjacency to fixpoint) so downstream obligations pull in sibling prerequisites, then topologically sorts the induced directed subgraph. Fail-closed superset applies when any touched id is unknown (per docs/design-t-wad-slice-7-binary-shim-affected-set-selection-canvas.md §3).

Authority: docs/briefs/r3-wave1-s6-slice7-affected-set-impl-worker.md Phase B; substrate carrier dsl/gunbc/ci.dag (CIWorkflowDag / CIGateEdge). Git, path-regex, and PR #2713 lens mapping stay outside this module (single-authority at this boundary).

Phase C scaffolding: selection_subset_under_touch_set_growth documents the monotone set-inclusion witness used by ratchet tests.

P5(b) per-PR receipt (INVARIANTS Dispatch-Discipline Mechanisms (b))

Single checkable receipt: SG-0 home-of-record — src/v3/compiler/src/gunbc_ci.rs added to EXPECTED_HAND_AUTHORED_NON_TEST in src/v3/compiler/tests/integration/sg0_census_test.rs with matching dissolution row in INVARIANTS.md under SG-0 hand-authored compiler non-test paths (ROADMAP.md § Forward-Tracked Lane: T-Workflow-As-Data, ≈L57–L63; program gate #103 ci_uses_affected_set_selection per docs/r3-program-plan.md + the Slice-7 worker brief).

Test plan

cargo test -p v3-compiler gunbc_ci — pass (7 unit tests).
cargo test -p v3-compiler sg0_expected_list_is_sorted_and_unique sg0_v3_non_test_hand_authored_subratchet — pass (SG-0 census invariants after the new EXPECTED_HAND_AUTHORED_NON_TEST line).

Response to review #10458 (claude-opus-4-7)

P5 / SG-0: Addressed on 53cee5001. src/v3/compiler/src/gunbc_ci.rs is now on EXPECTED_HAND_AUTHORED_NON_TEST with the paired dissolution row in INVARIANTS.md § SG-0 hand-authored compiler non-test paths — ROADMAP.md § Forward-Tracked Lane: T-Workflow-As-Data (≈L57–L63) + gate #103 authority (docs/r3-program-plan.md, Slice-7 brief). The PR description P5(b) section states this as the single per-PR checkable receipt.

Doc vs implementation: The public docs now describe symmetric edge expansion to fixpoint (connected component under from ↔ to), then topo-sort on the directed prerequisite subgraph — matching the loop and the lint → l1-ratchet → co-parent tests test.

Response to codex review (REQUEST_CHANGES — malformed DAG / cycle handling)

Addressed in 02aed2598:

Unknown edge endpoints: select_affected_gates now rejects any CIGateEdge whose from or to is absent from CiWorkflowDagInput::gates with CiAffectedGatesError::UnknownEdgeEndpoint before closure (roster authority preserved).
Topo fallback: Kahn incompleteness (cycle or broken subgraph) now returns CiAffectedGatesError::NonAcyclicPrerequisiteGraph instead of a sorted fake order.

API is Result<Vec<CiGateId>, CiAffectedGatesError>. Hermetic tests cover phantom endpoint + a↔b cycle.

BLOCKING (1)

Root Cause

src/v3/compiler/src/gunbc_ci.rs CiWorkflowDagInput admits non-unique gate ids and the error model only covers unknown endpoints/cycles → add duplicate-id validation or make the roster keyed by a unique-id carrier before selection.

⚠️ One malformed-carrier case still fails open by collapsing gates, so this should be tightened before the selection surface lands.

BLOCKING inline (duplicate roster / HashSet collapse) — addressed

select_affected_gates now calls validate_unique_gate_roster before building the known: HashSet<&str> roster. Duplicate [CiGateMeta::id] values return CiAffectedGatesError::DuplicateGateRosterId (no silent drop). Doc + hermetic test select_affected_gates_rejects_duplicate_gate_roster_ids.

validate_unique_gate_roster runs before HashSet construction so duplicate CIGate.id rows cannot collapse silently (P2/P3). Co-authored-by: Cursor <cursoragent@cursor.com>

claude-opus-4-7 APPROVE + exploratory notes

Approve: Taken as-is — thanks for the P5 / modeling read.

Exploratory (deferred, non-blocking):

selection_subset_under_touch_set_growth → Result<bool, …>: agree it would separate “subset false” from “either side Err”; leaving bool for now since the helper is only used by hermetic unit tests and the doc already states both-Err → false. Happy to widen the witness API in a tiny follow-on if a consumer needs the distinction.
Symmetric closure: remains intentionally load-bearing; module rustdoc + select_affected_gates_lint_only_pulls_l1_and_shared_prereqs pin it.

Merge readiness (dashboard): dashboard-ops reviews still shows codex REQUEST_CHANGES on an older SHA (pre duplicate-roster / fail-closed topo fixes); current HEAD 598e50ea5 has claude + cursor approvals. Not squash-merging until dashboard clears codex (or a fresh codex pass on HEAD) and v3 check finishes green.

claude-opus-4-7 (review 10523) — APPROVE + symmetric vs directed

Verified on HEAD: The exploratory note matches the implementation: select_affected_gates expands the seed under symmetric adjacency on prerequisite edges, so the affected vertex set is the whole weakly-connected component before topo on the directed subgraph (see module rustdoc “Expansion semantics” / select_affected_gates doc: connected component under symmetric closure).

No commit: This is an APPROVE with a non-blocking product/dissolution observation. A strictly downstream-only walk would indeed yield a (possibly) smaller plan; that alternative belongs in the .dag-owned dispatch lane called out in ROADMAP / the P5 receipt (no parallel Rust mirror over dsl/gunbc/ci.dag), not as a silent semantic change to this ratchet substrate. Current behavior is an explicit, documented choice for the demo-shaped carrier + tests.

cursor/composer-2 (review 10538) — APPROVE + PR body / `blocking`

Diff / mechanism (b): Confirmed — no doc violation on changed lines; SG-0 census line and matching INVARIANTS.md row are paired in the same change.

PR description (out-of-diff): Checked on the PR page — body already carries SG-0 hand-path delta / pairing at column 0 and a P5(b) subsection with the single checkable receipt (census + INVARIANTS dissolution row citing T-Workflow-As-Data / gate #103 / program plan + brief). No edit needed for social template.

Exploratory CiGateMeta::blocking: Already pinned on 1653318fc: CiGateMeta rustdoc states select_affected_gates consults only id; blocking is DSL carrier parity for CIGate-shaped BinaryShim / dispatch wiring (not dead weight).

BLOCKING (1)

Root Cause

src/v3/compiler/src/gunbc_ci.rs CiWorkflowDagInput is accepted as an unvalidated Vec-based carrier and acyclicity validation is scoped to the selected component → validate the whole prerequisite graph before selection or introduce a validated acyclic workflow carrier.

ROADMAP — Verified

T-Workflow-As-Data / gate #103: The added SG-0 receipt ties the new hand-Rust path to the forward-tracked T-Workflow-As-Data lane and the ci_uses_affected_set_selection gate.

⚠️ One malformed-carrier path still succeeds in narrow mode, so the fail-closed DAG validation needs tightening before merge.

Inline review (`gunbc_ci.rs` — HashSet roster / duplicates)

Not reproducible on current HEAD: select_affected_gates calls validate_unique_gate_roster(dag)? before building known: HashSet<&str> from dag.gates. Duplicate CIGate.id values therefore return CiAffectedGatesError::DuplicateGateRosterId and never reach the HashSet roster view, so nothing is dropped from the plan silently.

Relevant order:

validate_unique_gate_roster(dag)? — rejects duplicate roster ids up front.
let known: HashSet<&str> = dag.gates.iter().map(|g| g.id.as_str()).collect(); — only runs when the roster is already proven unique (set size equals gates.len() for ids).

Module rustdoc and select_affected_gates_rejects_duplicate_gate_roster_ids already pin this fail-closed path (P2/P3).

If the inline thread was generated against an older SHA before validate_unique_gate_roster landed, please re-resolve against current head.

Inline review (`gunbc_ci.rs` — global cycle vs subset topo)

Verified valid on bce13c07: topo_sort_subset only ran on the symmetrically expanded touch component, so a directed cycle elsewhere could still yield Ok in narrow mode.

Fixed on aaf1fb5a4: After roster + edge-endpoint checks, select_affected_gates now runs topo_sort_subset(dag, &known)? once on the full roster vertex set, so the entire directed prerequisite graph must be acyclic before any touch expansion or empty-diff fast path. Rustdoc + NonAcyclicPrerequisiteGraph docs updated; new tests: select_affected_gates_rejects_global_cycle_even_when_touch_isolated, select_affected_gates_empty_touch_rejects_when_global_graph_has_cycle.

claude-opus-4-7 (review 10577) — APPROVE + non-blocking notes

Topo complexity: Confirmed — topo_sort_subset rescans dag.edges for each popped node (while × inner for), so work is O(|subset| · |E|) in the worst case. Gate rosters stay tiny; no change unless profiling says otherwise.

selection_subset_under_touch_set_growth: Confirmed — rustdoc already states both sides must be Ok for a meaningful subset witness; any Err collapses to false (carrier invalid vs genuine anti-monotonicity). Callers that need disambiguation should branch on select_affected_gates first; no API change in this PR.

cursor/composer-2 (review 10586) — APPROVE

Verified on 679d14ed: Matches the tree — gunbc_ci is pure Rust mirrors + select_affected_gates / Result errors; fail-closed paths cover duplicate roster ids, unknown edge endpoints, global prerequisite non-DAG (topo_sort_subset(dag, &known)? before touch expansion), unknown-touch superset, symmetric expansion + directed topo on the induced set; in-module fixtures align with TESTING.md unit-first posture. SG-0 / INVARIANTS pairing is out-of-diff on this head but already landed on the PR branch per prior commits.

No code change — review lists no findings.

Nit (selection_subset_under_touch_set_growth): Confirmed — false on either-side Err is intentional for the in-module ratchet witness; rustdoc already calls out both-Ok for a real subset read.

Conflicting dispatch vs the comment block above. Fix-forward: Phase A list now has only the gt_one addition (genuinely required for PolyLogExponent = Rational where gt_one). Explicit parenthetical: gt_zero extension NOT required; range allowed_carriers already includes Int for ExponentialBase. Only gt_one is new. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): gate #105 — Q6 zero-degree collision + Q7 worker semantics + AP count Codex BLOCKING review 4bd0cb5 — 2 BLOCKING + 1 non-blocking: 1. Q6 carrier admits degree=0 colliding with ConstantCost (n^0 ≡ 1): Fix-forward: keep ratified plain signed Rational carrier; add explicit canonicalize-fold rule canvas §6.1 + worker §6 algebra: `canonicalize(PolyCost(_, 0)) ⇒ ConstantCost(1)`. Same dissolution discipline class as Q2-Y LinearCost ≡ PolyCost(d=1) collapse. Single authority for "value=1 constant" via ConstantCost, not parallel via PolyCost(_, 0). 2. Q7 output-semantics drift between canvas + worker §14: Fix-forward: worker §14 reframed — symbolic_cost_of returns EXACT canonical SymbolicCost (Q7 contract change, not backwards-compatible reduction). Big-O is derived via dominant_term projection. Legacy single-term consumers MUST wrap with dominant_term; canonical-form change is expected and ratified. 3. Anti-pattern off-by-one (non-blocking): worker §11 enumerated 11 items but header + §12 + §13 + §15 PR template said 10. Fix-forward: updated all 4 cite-list surfaces to 11 (7 Director-enumerated + 4 Mgr-derived). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): gate #105 — Q6 Option B Practice-2 carrier refinement (msg_b80bcaa8) Director RATIFIED Option B on Q6 zero-degree Practice-2 tension via msg_b80bcaa8 (relayed by PM msg_9d248cbd 2026-05-13). Practice-2 carrier-level `where nonzero` refinement preferred over Practice-4 canonicalize-fold dissolution; sign-admission intent preserved. Director-distilled discipline rule (NEW, load-bearing): > Same-variant redundancy → Practice-4 collapse (Q2-Y LinearCost ≡ > PolyCost(d=1)). Cross-variant redundancy → Practice-2 carrier > refinement (PolyCost(d=0) ≡ ConstantCost(1)). Type-level state-space > tightening beats API-level normalization when redundant state crosses > variant boundaries. Canvas + worker fix-forward: - §1 PROMOTE / §3 Q2-Y candidate / §6 STOP-SIGNAL / §6.1 dissolution text: `Rational` → `Rational where nonzero` (sign-admission via msg_2c1bfb0e preserved; only degree=0 excluded) - Canvas §6.1: reframed from canonicalize-fold to carrier-level refinement; Practice-2 vs Practice-4 disambiguation rule encoded - Worker §5 Phase A KNOWN_PREDICATES list: add `nonzero` predicate (allowed_carriers: Rational; arg_shape: Bare); now 2 new predicates (gt_one + nonzero), not 1 - Worker §5 "ZERO new authority" line: cite cross-variant vs same-variant rule - Worker §6 algebra table: canonicalize-fold rule REMOVED (type prevents construction); multiplicative cancellation rule split into d1+d2≠0 and d1+d2=0 cases (=0 maps to ConstantCost(1) directly without PolyCost(d=0) intermediate which is type-rejected) - Worker §7 bootstrap ratchet: type-rejection negative test added (PolyCost(_, Rational(0)) must be structurally rejected; ±n admits) - §11 anti-pattern #12 (new, Director-added): forbid canonicalize-fold for cross-variant redundancy when carrier refinement available - AP cite-list counts: 11 → 12 across §11 header / §12 / §13 / §15 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): gate #105 canvas — reconcile Q2-Y refinement + variant arithmetic Cursor APPROVE_WITH_COMMENTS 10980 — 2 internal-consistency findings: 1. Q2-Y parenthetical "no where refinement" contradicted the snippet directly above showing `where nonzero` (post msg_b80bcaa8 Option B). Reconciled: explicit "no positivity / gt_zero refinement" framing per Director msg_2c1bfb0e sign-admission intent, AND explicit acknowledgment that `where nonzero` IS present per msg_b80bcaa8 Practice-2 carrier-level Option B (sign-orthogonal, excludes only 0). 2. Q2-Y Pros bullet "11 → 10 net" contradicted §4 closing "**9** net under Q2-Y". Reconciled: corrected to "7 → 9 net" matching §1 ratified scope (+3 new variants -1 collapsed = +3 net over existing 7) and §4 closing reconciliation pointer. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): gate #105 — codex 77088ff non-blocking wording hygiene Codex no-blocking + 2 non-blocking improvements (77088ff review): - worker L156: "no such refinement" → "no positivity refinement, but DOES carry where nonzero" (clarifies sign-admission vs zero-exclusion distinction for downstream readers). - canvas L285: §10 anti-pattern header "7 Director + 3 Mgr-derived" → "7 Director + 5 Mgr-derived; 12 total" (matches actual 12-item list per worker §11 cite-list). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: R3 Substrate Mgr — lane through R3 close * docs(r3): gate #105 — named NonZeroRational alias (codex worker:167) Codex BLOCKING worker:167: inline `Rational where nonzero` in struct field types is unsupported by HEAD parser/lowerer — `where` refinements attach only to type aliases / parameters (precedent `type PositiveInt = Nat where gt_zero` at dsl/std/integer.dag:181). Inline use would require unsupported substrate syntax instead of making illegal degree=0 unrepresentable through a proper named refinement carrier. Fix-forward: introduce `type NonZeroRational = Rational where nonzero` at the type-alias layer (alongside existing `PolyLogExponent = Rational where gt_one` + `ExponentialBase = Int where range(min: 2)`). PolynomialCost.degree field type references the named alias: `degree: NonZeroRational`. Updates across both briefs: - All `degree: Rational where nonzero` → `degree: NonZeroRational` (5 canvas occurrences + 10 worker occurrences) - Worker §5.0 dag block: NonZeroRational alias declaration added with rationale comment citing codex worker:167 + HEAD parser constraint - Canvas §6 refinement-carriers list: NonZeroRational row added with named-alias note - Worker §5.0 HARD STOP directive: NonZeroRational added to the hard-stop list (named alias, not fresh record); HEAD parser constraint cited - Worker §10 STOP #4 variant-collision list: NonZeroRational added - Worker §5.0 P1/P2 narrative: clarified "DOES carry NonZeroRational named-alias" framing - Worker §7 bootstrap ratchet test: type-rejection test asserts both the type-alias declaration AND the degree=0 rejection at carrier level - Worker §13 verification axis: NonZeroRational added to refinement- carriers test list INVARIANTS P2 + Practice 2 carrier-level illegal-states-unrepresentable satisfied via named alias (P5 / parser-supported substrate syntax). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(r3): gate #105 canvas — fix §6 'no refinement' stale text (codex canvas:218) Canvas §6 closing paragraph still said "PolynomialCost.degree intentionally has no refinement" — pre-msg_b80bcaa8 framing that contradicts the NonZeroRational alias declared 3 lines above + ratified by msg_b80bcaa8. Fix-forward: reframe as "no positivity refinement, but DOES carry NonZeroRational named alias for zero-exclusion". Sign-admission preserved (msg_2c1bfb0e); zero-exclusion enforced (msg_b80bcaa8). Also added explicit reference to degree=0 alongside exponent≤1 / base≤1 in the structurally-unrepresentable set.

Canvas STOP-SIGNAL aligned to msg_d86a5987 for single-authority trace. INVARIANTS P2 single authoritative trace restored.
