release-gate-ledger

Runs the three pre-launch passes in order and has each lane write its own rows into one release-gate ledger through a validating recorder, instead of a chair copying tables after the fact. Produces three separate verdicts and one release posture (HOLD or ready) computed by script. Use when the three lane skills carry the ledger patches below, or when someone asks for the ledger variant of the release gate, for a site or client app you own or are authorized to test; a plain go/no-go belongs to release-gate-chair. Ships the three upstream patches that teach web-preflight, pre-ship-security-red-team and pre-ship-performance-audit to append their own rows — unapplied, because those are published skills. A pass in one lane never covers another. Not for a single-lane check, not for the default go/no-go (use release-gate-chair), not for penetration testing of production, not for performing the deploy.
