/**
 * audit-command-cutover.test.cjs — ADR-959 phase 4d-impl-3 equivalence tests.
 *
 * Verifies that `audit-uat` and `audit-open`, after cutover from the hardcoded
 * `case 'audit-uat':` and `case 'audit-open':` arms in msd-tools.cjs to the
 * capability registry dispatch path (default → dispatchCapabilityCommand →
 * audit-command-router.cjs → routeAuditUat | routeAuditOpen), behave
 * identically to the old inline cases.
 *
 * Test categories:
 *   1. UNIT (recording mock) — precise arg/call equivalence for each router
 *   2. DISPATCH — commands reach routers via default-case registry dispatch
 *   3. BEHAVIOR — subprocess tests with real output-shape assertions
 *   4. JSON-ERRORS — structured {ok:false,reason,message} for error paths
 *   5. REGISTRY — commandFamilies entries, audit capability in registry

 *
 *   1. Bare `output(...)` calls (only `core.output` is in scope) → ReferenceError.
 *   2. Even after switching to `core.output(formatted, raw)`, the human-readable
 *      branch JSON-stringifies the formatted string because `core.output` only
 *      bypasses JSON encoding when called as `core.output(null, true, rawValue)`.
 *      Result: stdout contains `"### Milestone Close: …\n…"` (a JSON string
 *      literal) instead of the rendered report.
 *
 * The shape assertions below catch both regressions structurally — never via
 * substring matching on serialized output:
 *
 *   - text mode: parse stdout as a sequence of lines and assert the expected
 *     section headers exist as standalone lines (i.e. raw text, not escaped).
 *     If the report is JSON-stringified, the stdout is a single line wrapped
 *     in double quotes with `\n` escapes — line-array assertions fail.
 *   - --json mode: JSON.parse the stdout and assert the keys returned by
 *     `auditOpenArtifacts(cwd)` (scanned_at, has_open_items, counts, items)

 * Regression tests for bug #950
 *
 * audit-open chronically flagged genuinely-complete quick tasks as [unknown]
 * because NO shipped summary template carried a `status:` frontmatter field —
 * so status was only emitted when the writing agent improvised it.
 *
 * The fix: add `status: complete` to all four summary templates and enforce it
 * in the executor agent + quick.md workflow. Tests here exercise the scanner
 * directly via auditOpenArtifacts() and also guard template text as a secondary
 * contract check.
 *
 * Primary guard:   behavioral audit-scanner tests (tasks read by scanQuickTasks)
 * Secondary guard: template-contract text checks (template text IS the runtime contract)
 * Writer-path guard: contract assertions on quick.md + msd-executor.md (source-text-is-the-product)

// so an item still unresolved when a milestone closed now resurfaces at
// EVERY later close, forever — `[A] Acknowledge all` documented that
// decision to STATE.md but never suppressed it. This suite verifies the
// suppression seam: `audit_acknowledged` is VERDICT-PRESERVING (never
// touches the artifact's own `status:` verdict) and SELF-INVALIDATING (a
// stale acknowledgment resurfaces automatically the moment the artifact's
// current state stops matching the marker's recorded snapshot).
