fix: address pre-landing review (codex) on the carve

- cso section: add a scope-gate header so '--owasp' (and other scoped modes)
  run only their selected phases, not every phase bundled in the section
  ('execute in full' no longer overrides Mode Resolution).
- carve-guard-checks: gateAfterStop now compares against the LAST STOP, not the
  first, so a gate stranded between two STOPs in a multi-STOP skeleton fails.
- TODOS: behavioral section-loading hermeticity (verifier matches global-install
  path, not the fixture) — pre-existing in auq-sdk-capture.ts, deferred.

+### P2: Harden behavioral section-loading test hermeticity
+
+**What:** `captureSectionReads` in `test/helpers/auq-sdk-capture.ts` accepts ANY
+Read whose path matches `sections/<file>.md`. The skeleton's STOP-Read directive
+points at the gstack-root install path (`scripts/resolvers/sections.ts` builds it
+from `ctx.paths.skillRoot`), not the planted fixture copy. So a run can satisfy
+the section-read assertion by reading the GLOBAL install's section instead of the
+hermetic fixture.
+
+**Why:** A behavioral test that passes by reading the global install doesn't prove
+THIS branch's carved section loads. If the fixture's section were broken but the
+global install's weren't, the test would still pass.
+
+**Context:** Codex outside-voice finding on the carve-guard ship (v1.57.0.0).
+Pre-existing in `auq-sdk-capture.ts` — affects `skill-e2e-ship-section-loading`,
+`skill-e2e-plan-ceo-review-section-loading`, and the new
+`carve-section-loading.test.ts`. Fix: match the fixture's ABSOLUTE sections path
+(the `planDir` copy), not a bare `sections/<file>.md` regex; or rewrite the STOP
+path to the fixture during the run.
+
+**Effort:** S (human ~3h, CC ~30min). **Depends on:** None.

 Scan git history for leaked credentials, check tracked `.env` files, find CI configs with inline secrets.
