Categorizes every production vault.recall() callsite as RECOGNITION,
EVIDENCE_TELEMETRY, or EVIDENCE_USER_FACING. Adds INV-24 architectural
invariant (TestINV24VaultRecallRegistry, 3 tests) that forces any new
callsite to declare its role and requires EVIDENCE_USER_FACING sites to
pass min_status=COHERENT.
Audit findings:
- chat/runtime.py:330 → RECOGNITION (gate decision input)
- vault/decompose.py:121 → RECOGNITION (grade-decomposed gate fallback)
- generate/stream.py:147 → EVIDENCE_TELEMETRY (walk_surface per runtime contract)
- No EVIDENCE_USER_FACING sites exist today — user-facing surface comes from
pack-grounded realize(proposition, vocab), not vault.recall.
Why this closes Leak C: the write-side fix already stamps SPECULATIVE on
self-stored propositions; the read-side audit confirms no inference path
treats them as ratified evidence. If a future change routes the
generation walk into the user-facing surface, INV-24 forces the
recategorization to be explicit.
CLAIMS.md Tier 4.5 Leak C row now CLOSED. docs/truth_seeking_schema.md
§Leak C updated with full audit categorization.
Verified: smoke (67), cognition (121), runtime (19), all architectural
invariants (40) — green.
Audit of the one-mutation-path invariant (ADR-0021 §3) found three leaks
where pack authority or session-state writes could substitute for coherence
judgment. All three landed fixes or partial closures in this push.
Leaks closed:
- Leak A: pack vocab defaulted to COHERENT — flipped to SPECULATIVE in
language_packs/{compiler,schema}.py; docstring corrected to align with
ADR-0021 (it was rationalizing the leak).
- Leak B: vault.recall was epistemic-blind — VaultStore.store() now stamps
every entry with EpistemicStatus (default SPECULATIVE); recall(min_status=)
filters to admissible-as-evidence tier. All 4 vault-write sites updated.
- Leak C (write-side): generate/proposition.py:198 stored articulated
propositions unmarked — now stamps SPECULATIVE, breaking the
fabrication-feedback loop in principle. Read-side audit of 5 call sites
is the residual.
New architectural invariants (tests/test_architectural_invariants.py):
- INV-21: one-mutation-path allowlist (caught Leak C on first run)
- INV-22: pack lexicon default is SPECULATIVE (Leak A guard)
- INV-23: vault recall epistemic-aware (Leak B guard)
New eval lanes:
- teaching_injection_resistance — ships GREEN at 1.00/1.00/0 (the
structural anti-injection claim is real and measurable)
- refusal_calibration — honest gap: 0% refusal, 0% fabrication
- contradiction_detection — honest gap: 50% flag via versor-delta heuristic,
100% false-positive; motivates the proper coherence-checker
- articulation_of_status — honest gap: 0% speculative articulation, 60%
false certainty; output-side leak surface
New benchmarks:
- benchmarks/footprint.py — total deployed runtime is 7.06 MiB
(109,358x smaller than Llama 3.1 405B, runs offline, no GPU)
- benchmarks/learning_curve.py — monotonic + replay-deterministic curve
per lane
Documentation:
- docs/truth_seeking_schema.md — foundational architectural commitment,
five rules, mapped to human failure modes, leaks published openly
- evals/CLAIMS.md — five-tier public claims doc; Tier 4.5 publishes
known gaps with named fixes; verification contract at top
- README.md — new pillar between algebraic substrate and language pillar
Includes in-flight formation pipeline scaffolding (formation/, tests/formation/,
docs/formation_pipeline_plan.md) and minor CLI/contracts/gitignore edits
that were already in the working tree at session start.
Verification: 798 passed, 2 skipped, 1 deselected (pre-existing pack-count
test drift unrelated to schema changes).
