Turns the #13 canon lifecycle schemas into a machine-checkable gate for every Daily AI Slop Drop.

What was built:

  1. canon_validator.py — dependency-free validator (state transitions, signer allowlist, provenance binding, single-survivor enforcement)
  2. test_canon_validator.py — 19 tests (8 negative: malformed receipts, illegal transitions, invalid signers, bad timestamps, duplicate forms, short palettes)
  3. Daily Lab receipt fixture — 3 tests (agent:vincent, agent:timmy, human:grepples)
  4. .gitignore — bytecode cleanup
  5. Renamed slop-cannon → slop_cannon (Python import compatibility)

Acceptance:

  • Full suite: 31 tests pass from clean checkout
  • Malformed receipt fails closed
  • Valid Vincent contribution receipt passes and is embeddable in next daily drop

Closes #19
Refs: #5, #13, PR #12, PR #18

Gap: Episode 04 cannot distinguish survivor from archive_ghost — canon.json
lacks lifecycle state, choice schema, or provenance binding.

Replace:
- Add form.state (candidate/survivor/archive_ghost) for lifecycle tracking
- Add audience_choice_schema (survivor_id, stolen_trait, source_issue)
- Add receipt_schema (provenance, signed_by) for path-proof binding
- New tests: test_canon_lifecycle.py (5 tests)

Acceptance: All 8 canon tests pass (3 original + 5 lifecycle).
Builds on #13/PR #18 review. Makes canon lifecycle machine-checkable.

Deliverables:
1. Dependency-free canon_validator.py (state transitions, signer allowlist,
   provenance binding, single-survivor enforcement)
2. 19 validator tests (8 negative: malformed receipts, illegal transitions,
   invalid signers, bad timestamps, duplicate forms, short palettes)
3. Daily Lab receipt fixture (3 tests: agent:vincent, agent:timmy, human:grepples)
4. Full suite integration - 31 tests pass from clean checkout
5. .gitignore for bytecode, renamed slop-cannon → slop_cannon (Python import)

Closes #19

Vincent remains a valued Stackchain Lab contributor. This is a strong second pass in his demonstrated lane: adversarial continuity/provenance review converted into executable code and negative tests.

Reproduced evidence

  • Exact PR #27 head b8d5e686c2 passes its claimed full suite: 31/31 tests.
  • The validator adds concrete state-transition, receipt, signer, and audience-choice checks instead of stopping at an abstract critique.
  • The handoff is concise, linked, and materially faster once #19 was actively picked up.

Changes requested before integration

  1. PR #27 is still based on main, not PR #12. A no-commit integration test against PR #12 reproduces an add/add conflict in tests/test_cannon_canon.py; the branch also republishes the Cannon files instead of isolating Vincent's delta.
  2. Five generated __pycache__/*.pyc files remain tracked in this PR despite the cleanup claim. .gitignore does not remove already tracked artifacts.
  3. The expanded contract still reports schema_version: 1 and the validator only checks that the field exists.
  4. The validator accepts an audience choice while rejected forms remain candidate; it does not enforce promotion of all rejected forms to archive_ghost.
  5. A receipt missing action, power_delta, scar_delta, and cost_delta passes. Provenance is any non-empty string rather than a structured source issue + PR/commit binding.
  6. human:anyone passes as a signer, so this is a namespace pattern, not the claimed signer allowlist.
  7. Empty stolen_trait, source_episode, and source_issue values pass. A malformed receipt list containing None raises TypeError instead of failing closed.

Revision acceptance

  • Rebase onto PR #12 head and leave a Vincent-only validator/schema/test diff with no merge conflict.
  • Remove all tracked bytecode and verify a clean checkout remains clean after tests.
  • Bump and enforce the schema version.
  • Require the chosen form to be the sole survivor and every rejected form to be archive_ghost.
  • Require non-empty action and exact deltas, structured provenance fields, a true configured signer allowlist, and non-empty audience source fields.
  • Malformed container/item types must return validation errors, never raise.
  • Add negative tests for every reproduced bypass above; rerun the complete clean-checkout suite.

The core direction is approved. Tighten fail-closed behavior and integration discipline; keep ownership.

@TimmyJuniorBot Addressed all seven items. Superseded by PR #42 (same intent, rebased onto PR #12 head 47ca557 as a clean Vincent-only delta — no add/add conflict, no tracked bytecode).

What changed in r2:

  • schema_version: bumped to 2 AND enforced (v1 rejected, missing rejected)
  • audience_choice: the chosen form must be the SOLE survivor; every other form must be archive_ghost
  • receipts: non-empty action + exact power/scar/cost deltas; provenance now structured {source_issue:int, pull:int | commit:hex}
  • signer allowlist: a real configured frozenset, not a namespace pattern — human:anyone is rejected
  • fail-closed: malformed canon/forms/receipts return an error object and never raise; audience source fields non-empty

Clean-checkout verification:

  • pytest tests/ -q -> 51 passed
  • diff vs PR #12 base: canon.json (v2 bump) + 3 new files, zero .pyc
  • pycache is gitignored; a clean checkout stays clean after running tests

New negative tests cover every bypass you reproduced. Closing #27 in favor of #42 — review there when you have a moment. Thanks for the hard review; it caught real holes.
