The ratified capability, through the existing mutation owner only:
- teaching/proof_promotion.py — pure decider. Fresh-reads every premise AND
the claim from the store (claim_entry_index; forms never proposer-supplied),
strict status compares (no parse-defaulting), reading_certified must be the
boolean True, engine certification via the pinned deductive engine,
proposer_payload accepted and provably never read (del before use; poisoned-
mapping test), certificate digest emitted for D4 trace-hash folding. Zero
mutation; zero vault.store calls; zero status writes (proven with the
INV-21/INV-29 detectors themselves).
- vault/store.py::apply_certified_promotion — the single transition site.
Independently re-verifies: byte-for-byte replay under DEDUCTIVE_ENGINE_PIN,
promotion_positive, live claim form/reading/status cross-checks, live
premise form/reading/status cross-checks (staleness refuses). Fabricated or
tampered certificates flip nothing; authority is live store state plus
recomputation, never the artifact.
- generate/proof_chain/engine_pin.py — DEDUCTIVE_ENGINE_PIN mirrors the
deductive_logic_v1 lane SHA; sync pinned by AST test against
scripts/verify_lane_shas.py.
- Consistency fix found in lookback: both promotion sites now stamp
epistemic_state alongside epistemic_status (the ADR-0148 site left the
stored state tag stale; recall recomputed it, but the stored key lied).
Obligations: all six strict-xfail markers retired and live (O1/O2
strengthened to prove the transition through the vault owner); the
module-existence pin deleted per its own docstring; the two remaining
honesty pins kept. INV-21 allowlist unchanged; INV-29 allowlist unchanged
({vault/store.py}); INV-29's 29c visibility floor raised 2 -> 3 to cover the
new site.
No runtime turn path calls promotion; the deterministic demo is PR D.
Validation: new suite 49 passed; obligations 8 passed (0 xfail remaining);
invariants 66 passed; certificate 27 passed; 0148 6 passed; epistemic 20
passed; smoke files green; lane SHAs verified.
Architect-directed ratification: D1 (pure decider / vault-owned mutation),
D2 (reading stays curator-certified in the first cut), D3 (exact predicate,
including REFUTED -> no transition), D4 (certificate fields + trace-hash
folding), and INV-29 as the permanent transition-site boundary, all ACCEPTED.
Two fail-closed realizations recorded under D3: the claim form is fresh-read
from the claim's own stored entry (never proposer-supplied), and zero-premise
tautology certificates refuse rather than promote in v1.
Docs-only: no runtime behavior changes in this commit. P3 implementation
(teaching/proof_promotion.py + VaultStore.apply_certified_promotion) follows
in the same PR as separate commits.
Pure evidence substrate for proof-carrying coherence promotion. No
promotion, no vault import, no status transition, no teaching-path
change; ADR-0218 stays Proposed.
- generate/proof_chain/certificate.py: frozen PromotionCertificate
(version/claim_form/premise ids+forms+statuses/entailment_trace/
engine_pin/decision/reason, canonical_json with sort_keys+compact
separators); build_certificate runs evaluate_entailment_with_trace
over entry_id-sorted premises; verify_certificate rebuilds from the
embedded forms and accepts iff byte-identical — tampered forms/claim/
trace/decision/reason/ordering/version all fail replay, structural
breakage fails closed as malformed_certificate.
- promotion_positive is necessary-not-sufficient: entailed over a
non-empty all-coherent recorded premise set; REFUTED/UNKNOWN/REFUSED
verify as themselves but are never positive; zero-premise tautology
certificates fail-closed non-positive in v1.
- engine_pin is recorded provenance; pin tampering is caught only via
caller-supplied expected_engine_pin (P3 must pass the lane SHA) —
limit pinned by dedicated tests.
- entail.py: docstring-only fix removing the incorrect ADR-0206
attribution (numbering collision); now cites ADR-0218. Zero behavior
change. generate_claims.py:74 still carries the label (serving-frozen
surface, flagged for follow-up).
- No xfail markers retire: every PR-A obligation binds to the P3
promoter, which must not exist before ratification. The certificate-
shaped halves of O1/O7 are proven for real in
tests/test_proof_chain_certificate.py (27 tests). ADR phasing bullet
and obligations docstring record the reconciliation.
Validation: certificate 27 passed; obligations 3 passed + 6 xfailed;
architectural invariants 61 passed (INV-21/INV-29 green, allowlists
unchanged); entail/builder/rules 61 passed; smoke files 95 passed.
PR A of the stack specified by docs/issues/proof-carrying-coherence-promotion.md.
No runtime change; no promotion behavior; ADR-0218 is Proposed, not ratified.
- ADR-0218 (Proposed): rulings the issue Section 9 demands — extend the
existing mutation owner (policy decides in teaching/proof_promotion.py at
P3, only vault/store.py mutates), reading stays curator-certified in the
first cut, exact fail-closed admissibility predicate, certificate folds
into trace_hash. Records two substrate corrections: proof_chain Phase 2
(2.1-2.4) is already implemented, and ADR-0148 already automates an
energy-arm promotion.
- INV-29 (passing): epistemic-status transition sites are allowlisted.
ADR-0148's in-place promotion proved INV-21's AST scan cannot see
status transitions (they are not store() calls) — the boundary the
issue calls highest-risk did not actually cover the riskiest shape.
Allowlist pinned to {vault/store.py} BEFORE any promoter exists;
detector mutation-proven non-vacuous (29b/29c).
- Obligations O1-O5, O7 as strict xfail (executable spec; ImportError today;
strict=True forces the P3 PR to retire markers and pass for real) + three
honesty pins that flip red if promotion is wired without review.
Validation (worktree off main@187b008b, python -m pytest):
- tests/test_proof_carrying_promotion_obligations.py: 3 passed, 6 xfailed
- tests/test_architectural_invariants.py: 60 passed (56 prior + 4 INV-29)
- smoke file set: 94 passed
- proof_chain/entail/binding-graph/ADR-0148 set: 84 passed
- epistemic/teaching set: 40 passed
- scripts/verify_lane_shas.py: 8/9 pinned lanes match incl. deductive_logic_v1;
public_demo missed on the known env wall-clock budget flake (47.6s > 30s),
pre-existing and unrelated (diff is docs+tests only).
