Useful beyond the agent loop (CI / pre-commit) + machine-readable

v0.2.0 — useful beyond the agent loop (CI / pre-commit) + machine-readable

v0.2.0 takes the proof-gate from an in-loop guardrail to something you can also
gate CI, pre-commit, and release on — and makes every decision
machine-readable so other tools can build on it.

What's new

• done-gate.sh assert — verify the ledger without running anything, for
  CI / pre-commit / release gates. Require one or more labels (--label,
  repeatable), reject stale receipts (--ttl), and constrain the recorded
  command class (--allow-command-regex / AGENT_DONE_ALLOWED_COMMANDS).

  bash done-gate.sh assert --label test --label build --ttl 3600

• --json on capture, assert, verify, and show — stable,
  dependency-free decision objects for Actions, hooks, and editor integrations.
• Trust pack: README badges, a comparison table (vs a plain CLAUDE.md
  rule), a "how it can and can't be fooled" threat model, an FAQ, SECURITY.md,
  examples/proof.jsonl, and an asciinema cast at docs/demo.cast.

Changed

• epoch is documented in proof.schema.json; freshness is judged from the
  recorded epoch, never file mtime.
• Tests: 18 → 28 (assert pass/fail/all-labels/ttl/regex + --json parse checks),
  green on Ubuntu + macOS.

Notes

• Backward compatible with v0.1.0 — capture / verify / show are unchanged;
  assert and --json are additive.
