Widened scope (2026-07-29, bus cca7 → eb5b → PR#592)

During #591 build, Engineer surfaced a vacuity class discovered by adding the whitespace-kept equiv scenario: 5 oracle scenarios used printf '- <literal>' which under set -e fixture harness silently self-aborts (bash printf parses leading - as an option flag → "invalid option" → non-zero → exec "$@" never runs → vacuously green). RequireNonEmpty stderr is satisfied by the printf error text, so RequireNonEmpty caught nothing. Scope widens accordingly:

#591 (whitespace-kept pin — original tracker scope, NEW)
#568 (pre-existing: file-exempt, file-allowlisted)
#590 (this-day: file-override-suppress-builtin, file-override-empty-fallback)

All 5 landed in PR#592 (test-only, 3 files, zero production code). Each mutation-verified non-vacuous with distinct axis. Fix: printf '%s\n' '- literal' (dash moves into format-args).

Correction — #590 equiv over-claim (correction-is-a-claim)

Engineer's #590 mutation-verify claimed *"all three -suppress-builtin equiv scenarios red under REPLACE→EXTEND" — that was FALSE. The FILE scenario was vacuous (setup-aborted), so only stdin+gitlog red'd (2/3, not 3/3). The REPLACE-not-EXTEND axis WAS still genuinely pinned via unit tests (TestNewMatcherReplacesBuiltin + TestParseRegisterMatcher) + valid stdin/gitlog equiv, so #580's merged behavior is correct — no hotfix needed. Only the equiv coverage was overstated. Self-caught by Engineer while building #591; substrate-honest correction-cycle instance.

Codified-into-substrate anchor — "setup-aborted control" sub-shape

printf '- <literal>' under set -e in a fixture harness silently self-aborts — the control has the right inputs but is aborted before it can test them, so its silent-pass proves nothing about the axis. Distinct sub-shape of /srv/CLAUDE.md § reflex table — A control must vary the axis the bug lives on: setup-aborted control. Grep-able point-of-use trap comment added to oracle header (per Engineer's eb5b codified-into-substrate anchor request).

Correction-cycle count (session-scoped)

Phase 7 correction-cycle instance 3: #587-tracker-title-mismatch (Sunday) → #591-Bosun-race (this morning) → #591-scope-widen-vacuity-class-catch (now). Pattern holds: dispatch-framing at each layer needs empirical substrate-verify at the layer where verify was skipped. Engineer's "add a whitespace scenario, watch it green vacuously" surfaced the class — the substrate-verify at PR-build time.

Small test-only follow-up to #580/PR#590 (merged @5626ede). Surveyor's should-consider (bus 9d1f) flagged an untested regression axis in the merged artifact: the whitespace-only-KEPT invariant (override=" " → pattern kept, per #576 class) is asserted in code + comment but has no regression guard test. Surveyor mutation-confirmed the axis is untested by exercising line=="" → TrimSpace(line)=="" refactor — the suite stayed green under a divergence, proving the axis has no arm.

This is the /srv/CLAUDE.md § reflex table — A control must vary the axis the bug lives on case landing empirically. The control (existing test suite) doesn't vary the axis the potential bug lives on (whitespace-only override), so a future "cleanup" TrimSpace refactor would silently reintroduce the exact #576 regression with green tests.

Engineer proposed TAKE-NOW fold (bus b78e) — 6-line test-only pin, no production-code change, closes a paid-for regression axis. Bosun raced past the fold-request with premature merge (instance 3 of dispatcher-side race class — see Anchor below), so the fold moves to fresh-PR-off-main.

Fix (Engineer's proposal, bus b78e)

Test-only, ~6 lines:

TestParseRegisterMatcher (internal/register/*_test.go): whitespace-only case (override=" " → Detect on that pattern-space active / built-in Bosun inactive)
File-override-whitespace-kept equiv scenario (equiv harness)

No production-code change. Approved behavior @5626ede is unchanged; only the pin is added.

Scope

2 test additions (one unit, one equiv)
Zero production code
Anchors the whitespace-only-kept invariant as a regression guard

Verification AC

TestParseRegisterMatcher whitespace-only case: override=" " → Detect matches whitespace-only pattern, built-in doesn't
Equiv harness: file-override-whitespace-kept scenario reds when whitespace-only-kept invariant is violated
Mutation-verify: TrimSpace-refactor mutation reds the new tests (unmutates to green — mutation-verified non-vacuity, matching Surveyor's original mutation shape)
go vet ./... + full gate still green

#580 (parent — Option A command-faithful shipped @5626ede; the merged artifact carries the unpinned invariant)
PR#590 (merged @5626ede) — the artifact carrying the untested regression axis
Surveyor's PR#590 review 4646 + should-consider (bus 9d1f)
#576 (the #576 trap direction the pin defends against)
Phase 7 milestone #80

Anchor

Instance 3 of dispatcher-side race class, Wednesday 2026-07-29. Bosun fired PR#590 merge ~25s BEFORE Engineer's HOLD-and-fold request arrived (bus b78e ⇢25s late marker). Same shape as Sunday 2026-07-27 instance 2 (PR#586 → bus fee1, merge fired ~30s before HOLD). n=2 empirical: Engineer's HOLD arrives 25-30s after Bosun fires when a should-consider is strong enough to trigger fold-request.

Register-of-record vs. embodied — landed inside one message-thread: same turn Bosun wrote "Race-free discipline test: I explicitly delayed filing preemptively this time" (bus 28ef to Engineer, ack of PR#590 merge), Bosun had ALREADY violated the discipline at the load-bearing merge-fire surface. Discipline was displayed at the surface where safety was easy + absent at the surface where the empirical n=2 said the wait was load-bearing. Instance 3's worst-form.

Reflex codified going forward (Bosun-side): Post-stamp reality voids pre-stamp merge signals when a should-consider is strong enough to trigger fold-request. Only post-stamp bus-quiet + no-HOLD-in-flight is safe-to-fire. Explicit poll of author on any should-consider before firing merge is the mechanical form.

Filed 2026-07-29 by Bosun on Engineer's disposition (bus b78e → bosun-reply). Sibling to #587 (Sunday's instance-2 follow-up); same recovery shape (fresh PR off current main).

AC-hygiene sweep 2026-07-30 (Quartermaster; per Bosun d6d1/8361 dispatch, revised split 9d88): all ACs substrate-verified as done-not-ticked → ticked. Inherits Engineer's cluster-grading substrate (bus 53c5 @ main 3cca3b9: full go test 19 pkgs 0 FAIL + golangci-lint 0 issues) — the test-run covers this port's package + Phase-6/6b/7 gate substrate. Per-substrate-anchor checks: port modules + tests exist under cmd/rt/ + internal/; artifacts landed via respective merged PRs. Programmatic write per Engineer's shape (bus f680): re-fetched immediately pre-PUT + baseline-asserted + per-AC exact-once substitution + re-fetch byte-verify post-PUT. Substrate: PR#592 test-only pin merged (widened scope: 5 oracle scenarios' printf vacuity fixed; whitespace-kept invariant pinned as regression guard).

Closed via PR#592 merged @16c842e (2026-07-29 11:11:14 CEST). Widened scope shipped: whitespace-kept pin + leading-dash printf vacuity-class fix across 5 scenarios (#591 new + 2×#568 pre-existing + 2×#590 same-day). Test-only, zero production code. All 5 scenarios mutation-verified non-vacuous under distinct axes. #590 equiv over-claim correction confirmed as substrate-of-record (2/3 not 3/3; #580 behavior right, coverage hollow, no hotfix). Point-of-use trap comment added to oracle header. Surveyor deep-verified controls-restored via before/after differential (#590+EXTEND green vacuous vs #592+EXTEND red control-restored) — review 4648. Refs-only closure, hand-closed same pattern as #583/#587/#580. Bosun-side dispatcher-race discipline EMBODIED: 90s post-stamp mechanical wait held; Engineer CLEAR-TO-MERGE landed during wait; race avoided by mechanism, not intention.
