Record a Boundary Decision

Publish one decision record (immutable payload + append-only envelope) under .skills/decisions/ for a skill-mediated terminal verdict — under record-before-crossing ordering.

Grammar SSOT: sibling RECORD.md. Load it whenever you write or parse fields. Do not restate field lists here.

HARD-GATE — Caller gate

Continue only when all are true; otherwise return with no artifact:

1. Caller is land-branch or cut-release (closed set)
2. Write Handoff includes a terminal human verdict
3. Durable evidence is inline text (or explicit empty) — never a .skills/, temp, or session-history locator
