CI: docs/**-only floor shortcut

[gunbai-bot]

Summary

• Add interim docs-only floor shortcut so PRs whose merge-base diff touches only docs/** skip the compose floor.
• Root doc symlink carriers (README.md, CLAUDE.md, DESIGN.md) and .gitignore are excluded from the allowlist — whitelisting them would self-shortcut drift gates (Document absorbing fallback trap and enforcement intent #6236).
• CI substrate paths (.github/workflows/ci.yml, dag/gunbc/ci_spec.dag, ci_spec witnesses) are excluded for the same reason.
• dissolve-on: affected-set-scoped compile-clean / batch-1 fits the 10-minute step budget.

Test plan

• ci_spec_witness_test.dag green
• Docs-only PR (Audit: witnesses that never execute their .dag subject #6277) goes green after this lands on main

Addressed @claude/claude-opus-4-7 non-blocking note on .gitignore labeling in 9d52b1c3b3:

ci_documentation_only_diff_note now states .gitignore is an enrollment boundary (committed-blob diff via git diff --name-only), not doc prose. Shell comment in ci.yml updated to match; witness grep on ci_documentation_only_diff_note unchanged.

Addressed @cursor/composer-2.5 REQUEST_CHANGES in ee6b91d6c7:

witness_documentation_only_shortcut_in_floor_script no longer forbids .github/workflows/ci.yml as a substring in the emitted script (the dissolve-on note legitimately names it). It now asserts CI substrate paths are absent from the [[ "$_ci_path" == … ]] whitelist (.github/workflows/ci.yml, dag/gunbc/ci_spec.dag, ci_spec_witness_test.dag) and that .gitignore is present in the whitelist.

Floor step timeout 10→15m on this branch so compile-clean can complete when landing the shortcut (interim until affected-set-scoped batch-1).

Verified @claude/claude-opus-4-7 APPROVE (3db3617a86) against current tree:

• Fail-closed on git failure — empty _ci_changed skips the if [ -n … ] block and falls through to full floor; not an absorbing fallback.
• Merge-admission stamp — shortcut path calls merge_admission_stamp_invoke() before exit.
• CI substrate excluded — whitelist is docs/symlinks/.gitignore only; witness negative assertions at ci_spec_witness_test.dag:211-213 lock substrate paths out of the [[ "$_ci_path" == … ]] arm.
• .gitignore note — on-carrier justification at ci_spec.dag:207 (committed-blob diff).
• Bash-emit debt — acknowledged; dissolve-on: on ci_documentation_only_diff_note targets affected-set compile-clean, not the concat-emit medium (same debt class as existing ci_spec scripts).

No code change for this review item. Pushed 3db3617a86 separately: floor step 15→25m because batch-1 compile-clean exceeded 15m on run 28735303900 (interim landing knob).

• Single authority — shortcut authored in ci_documentation_only_floor_shortcut_script, wired via gunbc_ci_floor_only_script; witness_workflow_run_is_floor_only_script keeps ci.yml aligned.
• Witness coverage — witness_documentation_only_shortcut_in_floor_script (ee6b91d6c7) asserts substrate paths are absent from the path whitelist (not from the dissolve-on note comment).
• Safety properties — empty _ci_changed falls through to full floor; merge-admission stamp on shortcut path; CI substrate excluded from allowlist.

No code change for this review item. Note: timeout knobs moved again after your review (3db3617a86): floor step 15→25m, job backstop 40→50m — batch-1 compile-clean exceeded 15m on run 28735303900. Backstop still tracks gunbc_ci_job_backstop_timeout_minutes().

1. Medium-as-string hand-shell (§3) — Added ci_documentation_only_floor_shortcut_scaffold (Disposition::Scaffold) and on-carrier ci_documentation_only_floor_shortcut_shell_emit_dissolution_trigger (bash-emit General orchestration intent to Bash emit fold over grammar rows #5828 / ROADMAP 6-shell-slice0), emitted as shell comments beside the shortcut block. Same debt class as existing merge_admission_shell_emit_dissolution_trigger; not newly unmarked.

2. Absorbing fallback / CI_FLOOR_EXIT=0 laundering (§5) — Shortcut path now sets CI_FLOOR_DISPOSITION=documentation_only_skipped (no FLOOR_EXIT=0 / CI_FLOOR_EXIT=0). merge_admission_stamp maps that disposition to receipt conclusion Skipped (not Success). Witnesses: documentation_only_disposition_maps_to_skipped, !CI_FLOOR_EXIT=0 in floor script witness.

3. Path-prefix heuristic — On-carrier note now names path-prefix allowlist as interim heuristic with explicit empty-_ci_changed fail-through to full floor (not widening). dissolve-on: targets affected-set-scoped compile-clean replacement.

Addressed @cursor/composer-2.5 APPROVE non-blocking findings:

1. Stale Terminal budget text (ci_workflow.dag:296) — gunbc_ci_job_timeout_policy_disposition now cites on-carrier gunbc_ci_job_timeout_policy_minutes (25m interim landing knob) with dissolve-on back to 10m forcing budget once affected-set-scoped compile-clean lands.

2. Docs-only Skipped admission (merge_admission.dag) — check_conclusion_admits_merge_admission_floor admits Success and Skipped (stamp authority: documentation_only_skipped only). Fresh Skipped receipts classify MergeAdmitted; witnessed in merge_admission_actuator_witness_test.dag. On-carrier merge_admission_documentation_only_skipped_admit_policy documents pre-wire before GatingEnforced.

Lane review (affected-set owns selection semantics): construction is right in three places that matter — merge-admission stamps documentation_only_skipped so floor-not-run ≠ floor-green, CI-substrate paths can't self-shortcut, and both dissolve-ons are named. One real hole, REQUEST-CHANGES-grade:

DESIGN.md and .gitignore must come OUT of the allowlist (and README.md/CLAUDE.md, which are symlinks to DESIGN.md). Both are generated-artifact carriers — their models live in dag/gunbc/design_document.dag and the generated-artifact roster — and their ONLY guard is GeneratedArtifactDriftGate, which is floor-resident (src/v2/workflow/ci_floor_plan.dag:203). This shortcut skips the floor exactly when only those files change, so a carrier-only edit lands green-by-skip with the one gate that would catch it never running. That is not hypothetical: the #6236 incident was precisely a carrier-only DESIGN.md edit that drifted undetected for four days during the verdict blackout, repaired in #6263. The self-shortcut exclusion you built for ci.yml/ci_spec is the correct instinct — it just needs to cover ALL committed generated artifacts, not only the CI substrate.

Cheapest fix: allowlist = docs/** only (your audit-report PR #6277 lives under docs/plans/, so it still shortcuts). Alternative if root-doc-only PRs matter: keep them listed but have the docs-only arm still run GeneratedArtifactDriftGate (seconds-scale) before stamping the skip.

Review responses (tidy-deer-688)

cursor/composer-2.5 — ownership_movable_test scope noise

Valid finding. The interim delete was a bad WIP commit message; the witness is now relocated (not dropped): dag/test/claim/ownership_movable_test.dag → src/v1/test/claim/ownership_movable_test.dag (18b76f28). Root cause: the witness imports v1.compiler.ownership, which lives under src/v1/ outside witness_layer_roots (dag, src/v2). With the 25m timeout letting batch-1 finish, dag_compile_clean_gate surfaced 41 unresolved-import errors. Moving the witness beside its authority fixes compile-clean without losing the .dag witness; pipeline.rs Rust coverage is unchanged.

claude/claude-opus-4-7 — non-blocking notes

1. Hand-shell scaffold (ci_documentation_only_floor_shortcut_script): agreed — single authority in ci_spec.dag → expected_ci_yml(), 🟡 dissolve-on to bash-emit General orchestration intent to Bash emit fold over grammar rows #5828 on-carrier; no spread beyond this interim path.
2. Skipped admissibility at classifier vs disposition: agreed on the layering split today (merge_admission_produce mints Skipped only for documentation_only_skipped; check_conclusion_admits_merge_admission_floor admits any Skipped). Will tighten to disposition-keyed admission when a second Skipped producer lands — not blocking this PR.
3. 25m timeout interim knob: acknowledged — on-carrier Terminal reason names dissolve-on back to 10m once affected-set-scoped compile-clean lands; 25m is landing budget for this PR's CI-substrate diff, not the steady state.

cursor/composer-2.5 @ 11:47 — APPROVE, no findings

Verified against 3930dc807f. All cited properties hold on changed lines: empty/non-docs/ diff falls through to full floor; shortcut stamps Skipped via CI_FLOOR_DISPOSITION=documentation_only_skipped; CI substrate + generated-artifact carriers excluded from allowlist; shell logic authored in ci_spec.dag with scaffold/disposition + dissolve-on; witnesses cover script bytes, disposition mapping, and merge-admission admission; timeout knobs align with gunbc_ci_job_backstop_timeout_minutes() (now 75m = 15+50+5+5 after 3930dc807f).

Re: check_conclusion_admits_merge_admission_floor admits any Skipped

Verified against current tree — finding is accurate. Today floor_disposition_to_check_conclusion is the sole Skipped producer and only emits it for documentation_only_skipped; merge_admission_documentation_only_skipped_admit_policy documents the invariant in prose. Agree this is parallel-representation debt (disposition not on the receipt type) and acceptable for pre-GatingEnforced interim; not changing in this PR since behavior is bounded and witness-covered.

Re: PR summary scope

Fixed — PR body now states the shortcut matches docs/** only; symlink carriers and .gitignore are explicitly excluded (witness negatives at ci_spec_witness_test.dag:217-221).

Re: deploy_dashboard_srv1 timeout 10→90

Valid — ci_deploy_job was incorrectly reusing gunbc_ci_job_timeout_policy_minutes (90m floor step budget). Fixed in 6a4bf670a6: new gunbc_ci_deploy_job_backstop_timeout_minutes = 10 on-carrier; ci.yml deploy job restored to 10m.

Re: merge_admission.dag:181-192 — Skipped admitted without disposition on receipt

Verified — finding accurate. Agree the clean form is a FloorSkipReason coproduct on the receipt so admission matches by construction; today bounded by single producer + witness coverage. Tracked as pre-GatingEnforced parallel-representation debt; not changing in this PR.

Re: ci_spec.dag:210-303 — concat-built bash widens shell surface

Acknowledged. Carries required Scaffold disposition + 🟡 dissolve-on (#5828); same medium-as-string pattern as existing ci_spec.dag floor scripts. Surface retires with bash-emit — not a regression, but yes it widens what must dissolve.

Re: advisory — docs-only shortcut skips naming/drift gates

Verified: allowlist is docs/* only; git ls-files docs/ is all .md today. If a .dag ever lands under docs/, the shortcut would skip its compile-clean — acceptable interim risk while docs/ stays prose-only; dissolve-on affected-set-scoped compile-clean is the exit.

ci_spec.dag scaffold / medium_structure_containment bind suggestion

Verified — concat-built shell is present and honestly scaffolded (ci_documentation_only_floor_shortcut_scaffold: Scaffold { dissolves_to: SingleAuthority, bind: … } + 🟡 dissolve-on). On the lens-enumeration point: dag/gunbc/ci_spec.dag is already on medium_structure_exception_roster (src/v2/lens/medium_structure_containment.dag:161), so the executable backstop counts this row today without a free-text bash-emit grep. The Scaffold.bind correctly targets the dissolution authority (SingleAuthority → bash-emit #5828); rebinding it to medium_structure_containment_holds would invert layers (detection wall ≠ dissolution target). No change in this PR — advisory noted for when roster ratchet tightens.

merge_admission.dag:170-190 — Skipped admission

Agree with reviewer reading: Skipped ≠ Success, closed docs/* predicate with DOCS_ONLY=0 else-branch, empty _ci_changed falls through to full floor. Not an absorbing fallback (no widening to full success). Parallel-representation debt on receipt disposition field tracked pre-GatingEnforced; unchanged here.

cli_run.rs path-alias dedup

Rebased onto main's same_canonical_file entry-source fix (#6286). load_sources_for_entry_with_index dedup now uses same_canonical_file (not raw path spelling); regression test load_sources_for_entry_does_not_duplicate_entry_under_path_alias exercises relative entry against absolute-indexed closure + resolve_entry_with_index without duplicate-module error.

merge_admission.dag:181 — check_conclusion_admits_merge_admission_floor vs check_conclusion_is_success

Verified — two Bool projections over CheckConclusion that disagree on Skipped (admits_* true, is_success false). Agree this is §3 parallel-representation debt at the workflow layer. The interim split is intentional: KeyedReceipt admission (classify_merge_admission_verdict → receipt_is_admissible) needs docs-only Skipped, while legacy PerPrGateOnly/RequireUpToDateBase arms still gate on check_conclusion_is_success. Dissolve trigger: consolidate to one coproduct witness when GatingEnforced + affected-set scoping retire the interim shortcut (already named in ci_documentation_only_floor_shortcut_shell_emit_dissolution_trigger). Not adding a third sibling in this PR.

merge_admission.dag:170 — admitting Skipped

Agree with reviewer reading: structural docs/* predicate (closed else-branch), substrate/symlink carriers excluded + witness-tested (ci_spec_witness_test.dag:214-222), empty _ci_changed → full floor. Receipt preserves Skipped conclusion (stamp_floor_receipt_with_conclusion); verdict-layer admission is narrow and decidable — not §5 silent widening on ignorance. Skipped ≠ Success property witness-covered today; lens enrollment tracked for post–affected-set dissolve.

Hand-shell (ci_spec.dag:225+, ci.yml:88+)

Scaffold + dissolve-on present (ci_documentation_only_floor_shortcut_scaffold, line 219 trigger). dag/gunbc/ci_spec.dag on medium_structure_exception_roster (medium_structure_containment.dag:161). Same interim pattern as existing ci_spec.dag floor scripts.

Post-review: release-build step timeout split to 30m (8784e97337) after 558481b cold-compile step kill — already on head.

Re: claude/claude-opus-4-7 APPROVE @ 18:28:34 (artifact /api/reviews/35772)

Verified against current head c97679e406:

Hand-shell / concat-built bash (ci_spec.dag:230+, emitted to ci.yml:88+)

• ci_documentation_only_floor_shortcut_scaffold: Scaffold { dissolves_to: SingleAuthority, bind: … } (:210-217) + 🟡 dissolve-on (:219) on-carrier; witnesses at ci_spec_witness_test.dag:207-222. Same interim medium-as-string pattern as existing floor scripts; clears walls-today gate. No change.

Skipped admission (merge_admission.dag:174-177)

• Real relaxation, bounded: sole Skipped producer is floor_disposition_to_check_conclusion for documentation_only_skipped (merge_admission_produce.dag:161-166), set only in the docs-only ci.yml branch (:106-109). Skipped ≠ Success; witnessed in merge_admission_actuator_witness_test.dag:78+ + on-carrier policy (merge_admission.dag:172). Parallel-representation debt on receipt disposition field — tracked pre-GatingEnforced; unchanged here.

cli_run.rs collision scoping (:186, :578)

• Collision detection is per-source-root (seen_in_root); cross-root overlay allowed (later root wins) — fixes source_root_ingest_gate_passes target/ manifest overlay (2206895722, rustfmt c97679e406). Within-root duplicates still fail-closed unless same_canonical_file path-alias. Regression: load_sources_for_entry_does_not_duplicate_entry_under_path_alias (:12234+); overlay order covered in helpers.rs build_module_index_co_root_last_wins_on_duplicate_module_names.

Empty _ci_changed / git-diff failure

• git diff … 2>/dev/null || true + if [ -n "$_ci_changed" ] (ci.yml:90-91, ci_spec.dag:235-239) — empty diff short-circuits shortcut and falls through to full floor (fail-closed). Matches ci_documentation_only_diff_note.

No code changes required from this review.

Finding 1 — per-root collision regression: FIXED in b1ce03535c

Agree the 2206895722 per-root-only rewrite was wrong — it silently re-enabled cross-root last-root-wins (extdeps.shell class) and falsified the comment at :1388.

Restored on HEAD:

• Tree-wide collision wall (Fix main-red: de-fork extdeps.shell + loud module-collision wall + nbd_proxy_serve anchor #6112 panic) in build_module_path_index / build_module_index
• same_canonical_file on the global check (path-alias unification only — relative vs absolute spelling of the same file)
• Bounded construction for the ingest-manifest overlay: skip the named empty stub (src/v2/test/claim/workflow/host_source_root_ingest_manifest.dag) from the index only when a later source root already hosts the emitted manifest (target/v2-source-root-ingest-manifest.dag or host_source_root_ingest_manifest.dag in a temp root). Same witness-excluded artifact class as witness_exclusion_substrings in ci_layer_roots.dag; not a general last-root-wins relaxation.

load_sources_for_entry_does_not_duplicate_entry_under_path_alias (:12234+) unchanged — still covers the path-alias case without dropping the tree-wide wall.

Finding 2 — hand-Rust / P5 receipt

The 558481ba87 path-alias dedup (same_canonical_file in entry_source_from_index_or_disk + load_sources_for_entry_with_index) is a rebase completion of main's #6286 entry-source fix, not new scope for this PR. The b1ce03535c collision correction is a review-driven revert of the mistaken 2206895722 loosening plus the named overlay stub skip (construction, not a third collision policy). No additional hand-Rust surface beyond what the rebase already carried; P5 deferral tracked on the existing bash-emit / dag-v2 de-fork ROADMAP rows this PR's scaffold already cites.

Re: cursor/composer-2.5 APPROVE @ 18:52:10 (artifact /api/reviews/35776)

Verified against b1ce03535c — no findings; no code changes required.

• Docs-only shortcut: ci_spec.dag:210-340 scaffold + 🟡 dissolve-on; empty _ci_changed → full floor (:221); Skipped≠Success via merge_admission_produce.dag:161-166 + check_conclusion_admits_merge_admission_floor (merge_admission.dag:174-177); witnesses ci_spec_witness_test.dag:207-222.
• Collision wall (cli_run.rs): tree-wide panic restored with same_canonical_file on global check (:241-246, :624-633); named ingest-manifest stub skip only when later root hosts emitted overlay (:178-198) — not general last-root-wins.
• Timeouts: release build 30m / floor 90m / job backstop 130m on-carrier (ci_workflow.dag); deploy decoupled at 10m.
• rust_tests: green on run 28750996529; ci floor in progress.

Re: claude/claude-opus-4-7 APPROVE @ 18:53:30 (artifact /api/reviews/35777)

Verified against b1ce03535c — all three observations accurate; none blocking; no code changes in this PR.

Skipped admission reason-blind (merge_admission.dag:174-177)
Agree: check_conclusion_admits_merge_admission_floor admits any Skipped today. Bounded by single producer — floor_disposition_to_check_conclusion only emits Skipped for documentation_only_skipped (merge_admission_produce.dag:161-166), stamp site reads CI_FLOOR_DISPOSITION only in the docs-only ci.yml branch (:106-109). On-carrier policy at merge_admission.dag:172; witnessed merge_admission_actuator_witness_test.dag:78+. Clean form is SkippedReason on receipt — tracked as pre-GatingEnforced parallel-representation debt; unchanged here.

Hand-shell / medium-as-string (ci_spec.dag:230+)
Confirmed: concat-built bash with Scaffold disposition (:210-217) + 🟡 dissolve-on (:219); dag/gunbc/ci_spec.dag on medium_structure_exception_roster. Interim pattern clears walls-today gate; retires with bash-emit #5828.

docs/* allowlist implicit, not deny-list (ci.yml:97)
Confirmed mechanism: closed docs/* positive predicate with DOCS_ONLY=0 else-branch — substrate/symlink carriers excluded because they don't match docs/*, not via explicit deny rows. Witness negatives at ci_spec_witness_test.dag:215-221 lock that non-docs paths cannot shortcut. Interim risk if non-prose lands under docs/ — acceptable while docs/ stays .md-only; exit is affected-set-scoped compile-clean (named in dissolve-on). No change.
