/**
 * E2E capability-wiring tests for the API-coverage gate (#1562).
 *
 * Drives the real CLI subprocess (`loop render-hooks verify:pre` and
 * `check api-coverage.verify-pre`) against temp projects to prove:
 *   - the gate is data-driven (activates/deactivates by config) — acceptance #5
 *   - the seal contract (block / pass) — acceptance #1, #2, #4
 *   - the matrix persists on disk and is read at seal time — acceptance #6
 *
 * CONTENT/E2E only: every test drives a real CLI subprocess. No readFileSync
 * source-grep. Genuine assertions: each case asserts the SPECIFIC differing
 * value (block true/false, capId presence), not a count.
