/**
 * qa-l9-matrix.mjs — the L9 release-candidate QA matrix, in one command.
 *
 * L9 = the final live keyed end-to-end QA pass
 * (P1-5) + the browser tracking gate (P1-7) + a re-confirmation of the release
 * bar, run against the release candidate before the repo goes public.
 *
 * This runner does everything in that matrix that a machine can honestly do:
 *
 *   A · REPO     static gates — unit suite, build, the Node-24 allocation gate,
 *                secret/private-name scans, LAN-safe defaults, public files.
 *   B · FEED     server-side probes — does each keyed proxy actually return
 *                live data, and does a MISSING key degrade honestly?
 *   C · APP      one real browser session — layers populate, credits list,
 *                clean-UI keeps attribution, no key leaks into the client.
 *   D · HARNESS  the existing qa-*.mjs fleet, invoked as subprocesses and
 *                aggregated. This runner never reimplements what they cover.
 *   M · MANUAL   the owner-eyes checks (3 voice mic round trips, the LAN
 *                warning, the live-vessel transfer, …). Always reported as
 *                SKIPPED/OWNER-RUN so the coverage math stays honest — the
 *                steps live in the maintainers' release runbook.
 *
 * Honest degradation is the core contract: a check that needs a key THIS run
 * does not have is SKIPPED with an OWNER-RUN tag, never failed. A FAIL always
 * means "the product is wrong", not "my environment was thin".
 *
 * Run:
 *   node scripts/qa-l9-matrix.mjs                        # against :4173
 *   node scripts/qa-l9-matrix.mjs --url http://localhost:4220
 *   node scripts/qa-l9-matrix.mjs --cheap                # read-only, no heavy harnesses
 *   node scripts/qa-l9-matrix.mjs --only A,B             # groups or ids
 *   node scripts/qa-l9-matrix.mjs --skip D8,D12          # drop specific checks
 *   node scripts/qa-l9-matrix.mjs --list                 # print the matrix and exit
 *   node scripts/qa-l9-matrix.mjs --json out.json        # machine-readable results
 *   node scripts/qa-l9-matrix.mjs --headful              # watch the browser group
 *
 * Exit codes: 0 = no FAILs · 1 = at least one FAIL · 2 = target unreachable.
