/**
* Static invariant tests for /spec (consolidates 13 gate-tier checks).
*
* Each test asserts a specific contract the spec/SKILL.md.tmpl must encode.
* If the template drifts away from a contract, the test fails immediately —
* no LLM, no E2E cost.
*
* Covers (W7 plan):
* spec-phase-gating — Phase 1 hard gate ("no issue after first message")
* spec-phase4-revise — Phase 4 "what did I get wrong" loop
* spec-dedupe-no-gh — graceful skip on gh missing / unauth / rate-limit
* spec-dedupe-matches — merge-with-or-file-new AskUserQuestion for matches
* spec-execute-dirty — porcelain check + 3-path AUQ + TOCTOU re-check
* spec-execute-race — unique branch spec/<slug>-$$ + SHA pin
* spec-quality-gate-fallback — codex timeout/unavailable skip-with-warn
* spec-quality-gate-redaction — fail-closed secret regex list + BLOCKED
* spec-quality-gate-secret-sink — invariant: raw spec not persisted on block
* spec-archive — gstack-paths eval + atomic tmp/mv + PID suffix
* spec-archive-sync-exclusion — /specs/ auto-exclude from sync allowlist
* spec-audit-flag — flag routes to Audit/Cleanup template
* spec-concurrency — PID suffix in branch + atomic archive write
* spec-plan-mode-detection — reads GSTACK_PLAN_MODE env
