/**
 * E2E content tests for plan:post hook — gap-analysis gate.
 *
 * ADR-857 phase 6 backlog: check-gap-analysis-plan-post-e2e.test.cjs
 *
 * Tests exercise:
 *   - loop render-hooks plan:post (gate discovery)
 *   - check gap-analysis.plan-post (advisory gate check)
 *
 * HARD RULES enforced here:
 *   - Every test runs a real CLI subprocess or the real resolver + real registry.
 *   - No readFileSync + .includes() source-grep on workflow files.
 *   - Asserts TYPED CONTENT (JSON fields, counts, booleans, strings).
 *   - Each test fully isolated (own fixture), cleanup in afterEach.
