* wip(b4): lift _basis to generate/epistemic_basis.py (behavior-preserving)
B4 PR-1 foundation checkpoint — the shared epistemic-basis helper extracted
byte-identically from determine.py so the closed-world frame_verdict evaluator
(coming) can compute standing without importing determine (ADR-0222 §8 A3).
determine.py imports it aliased; its 3 Determined sites + INV-30 unchanged.
PAUSED: rest of B4 (FrameVerdict type, evaluator, INV-31, PR-2/3/4) resumes
after the suite-speed arc.
* feat(frame-verdict): closed-world envelope + isolated evaluator + INV-31 (B4 PR-1)
The sealed, off-serving FrameVerdict type + the isolated text-frame evaluator + the
INV-31 firewall (ADR-0222). Composes proof_chain.entail (no second prover); a
closed-world False comes ONLY from an ROBDD refutation; absence is never false.
- generate/frame_verdict/{types,evaluate,__init__}: FrameVerdict / ClosedFrame /
ClosedWorldProof + PositiveRefutationKind enum. evaluate_frame_verdict(frame, query)
maps entail ENTAILED/REFUTED/UNKNOWN/REFUSED -> entailed_true/false/undetermined/
contradiction/scope_boundary; OPEN / undeclared-closure / non-TEXT -> scope_boundary.
__post_init__ admissibility: entailed_false needs a NAMED positive refutation; a
generic FALSIFIED raises. trace_hash is order-invariant + replay-stable.
- INV-31 (test_architectural_invariants.py): A1 determine.py clean+visible; A2 exact
construction allowlist (evals-inclusive, tests-excluded) + non-vacuity anchor; A3
transitive spine -/-> frame_verdict (reuses INV-27 walker) + resolve anchor; B1
determine() refuses a ClosedFrame. B2 deferred to the governance slice (no
non-vacuous surface yet; ADR §8 permits).
No serving wire. determine.py unchanged except the _basis import. No Determined(answer=False).
INV-30 green. Shapes follow the B4 operator master brief (PositiveRefutationKind enum,
closure_declared/source/provenance) — a consistent refinement of ADR-0222 §3.
Verified: 97 (full INV incl. INV-31 + FrameVerdict + OWA floor) + 20 frame_verdict + 35 determine.
* feat(frame-verdict): text closed-world (CWA) evaluation lane (B4 PR-2)
A measure-only lane over the text FrameVerdict evaluator (ADR-0222). Proves the sealed
type evaluates propositional closed frames safely — incl. a sound entailed_false —
without touching determine() or runtime serving.
- evals/frame_verdict_text_cwa/: cases.jsonl (12 cases across all 5 verdict kinds +
gating + absence safety), oracle.py (an INDEPENDENT truth-table propositional checker —
own recursive-descent parser + brute-force enumeration, disjoint from the ROBDD; imports
no engine module), score.py, README.
- tests/test_frame_verdict_text_cwa_lane.py: wrong=0; the disjoint oracle confirms every
gold (non-vacuity) AND the engine matches the oracle on every case; entailed_false is
proof-backed (ROBDD_REFUTATION); absence / OPEN / undeclared-closure are never
entailed_false; SHA-pinned fixtures.
Input contract: propositional-formula strings (no prose lowering). Capability-index
deliberately NOT touched (off-serving lane; documented). No Determined, no answer=False,
no serving wire. INV-30 / INV-31 / ProofWriter-OWA stay green.
* feat(frame-verdict): perception changed-slot falsification adapter (B4 PR-3)
Lift an ADR-0211 FalsificationRun into a FrameVerdict SAFELY (ADR-0222 §5.2). Critical
doctrine: "FALSIFIED" is not enough — only a POSITIVELY observed changed-slot contradiction
produces entailed_false (PERCEPTION_CHANGED_SLOT). Missing observation (absence), unexpected
extra (over-observation), and a whole-missing actual frame NEVER become false — they refuse
(undetermined / scope_boundary). SUPPORTED -> entailed_true (frame-conformance proven).
- generate/frame_verdict/perception_adapter.py: frame_verdict_from_perception_falsification;
the proof carries the FULL run trace_hash (binds expected+actual+verdict, ADR §5.4).
- generate/frame_verdict/_construct.py: extracted the single FrameVerdict builder; the text
evaluator + perception adapter both funnel through it, so the literal FrameVerdict(...)
lives in ONE file -> INV-31 ALLOWED_FRAME_VERDICT_SITES = {_construct.py}.
- tests: changed-slot -> entailed_false (+ empty-hash raises); missing/unexpected/whole-missing
never false; supported -> entailed_true; non-perception -> scope_boundary.
Off-serving; perception_adapter is in generate.frame_verdict, so INV-31 A3 already proves it
unreachable from the open-world spine. No determine() change, no answer=False. INV-30 / INV-31
/ ProofWriter-OWA / text-CWA lane stay green.
* feat(response-governance): default-dark FrameVerdict surface mapping (B4 PR-4)
The only lawful surface path for a closed-world verdict (ADR-0222 §7/§14). Lowers a
FrameVerdict to a served disposition through the EXISTING epistemic_disclosure tables (no
parallel object): entailed_true/false -> COMMIT at INFERRED + DisclosureClaim.NONE (a
committed "Yes"/"No"; entailed_false is an answer, NOT a contradiction/refusal/LimitationKind);
contradiction -> REPORT; undetermined -> REFUSE; scope_boundary -> EXPLAIN.
DEFAULT-DARK: a NEW module that changes no existing file — the open-world govern_response /
shape_surface STRICT path is byte-identical, and nothing in the live runtime calls it. The
TYPE is the closed-world tag: a forged dict / untagged object cannot widen serving (raises).
INV-31: A3 still green — core/response_governance/frame_verdict.py is NOT imported by the
package __init__ or the open-world spine, so frame_verdict stays unreachable from
chat/runtime/session/vault. The B2 anchor is now live (the forged-object rejection); all six
INV-31 anchors firm. The open-world render_determination cannot render a FrameVerdict;
determine() still has no answer=False.
Verified: 84 (governance + full INV incl. INV-31 A3/B2) green.
* harden(frame-verdict): fold in adversarial-review findings (B4)
A 4-skeptic adversarial read of PR-1..4 against real source surfaced one
soundness gap (major) and four defensive gaps (minor). All folded in; the
4 B4 files + full INV suite stay green (128 passed).
S1 (major) — perception negation was not frame-gated. The text evaluator
refuses OPEN / undeclared-closure frames (-> SCOPE_BOUNDARY) but the
perception adapter only gated frame_kind + the missing-frame sentinel, so a
PERCEPTION + OPEN + changed-slot residual produced entailed_false with
world_assumption=OPEN — a verdict that self-contradicts the type invariant
(OPEN => negation illegal). Fixed two ways:
* perception_adapter: gate OPEN / not-closure_declared -> SCOPE_BOUNDARY,
mirroring the text evaluator (graceful upstream refusal);
* types.__post_init__ §(0): STRUCTURAL backstop — ENTAILED_FALSE + OPEN
raises, frame-general, so NO producer (text/perception/future) can emit
an OPEN-world negation even if it forgets the gate.
S4-a — entailed_true was admissibility-asymmetric. Only entailed_false was
proof-gated at construction; a committed "Yes." leaned entirely on the
INV-31-A2 allowlist. Added a symmetric §(2) guard: entailed_true requires a
positive entailment/support proof (proof_chain.entail/ENTAILED or
sensorium.falsification/SUPPORTED), non-empty sha, and NO refutation kind —
a mutation test can now trip a forged positive.
S2 — A2 construction detector extended to flag FrameVerdict.<factory>(...)
classmethod constructions and module-qualified mod.FrameVerdict(...), so a
future alternate constructor cannot evade ALLOWED_FRAME_VERDICT_SITES. The
dataclasses.replace gap is RECORDED (a blanket replace() match would
false-positive tree-wide) for the serving-wiring PR, not faked.
S4-b/c — A3 firewall now bars core.response_governance.frame_verdict
DIRECTLY (not only via its re-import of generate.frame_verdict), plus a new
test proving the response_governance package __init__ stays default-dark
(does not re-export the adapter).
S3 — oracle grammar is a strict SUBSET of proof_chain.entail (it mis-parses
`false` as a free atom). Corrected the docstring and added a lane guard:
every DECIDED cases.jsonl formula must stay inside the subset, so a future
out-of-subset case fails loudly at SHA-add review instead of as a confusing
engine-vs-oracle red. SCOPE_BOUNDARY-gold garbage is exempt (both refuse).
S1-minor (construction-time-only admissibility) documented in __post_init__:
a future codec/deserialization path must re-construct via build_frame_verdict.
* docs(analysis): B4 FrameVerdict implementation lookback (PR-1..4 + hardening)
Mandatory multi-slice lookback (CLAUDE.md triggers 2+3). Audits all six B4
commits across the lookback template: documentation drift, test-coverage /
parity gaps, wrong=0 hazard surface, cross-slice consistency, honest LOC.
Categorized findings: solid (INV-30 untouched; entailed_false positive-only;
INV-31 firewall non-vacuous; default-dark; replay determinism) / hazards (the
5 adversarial-review findings, ALL fixed in the hardening commit) / recorded
gaps (dataclasses.replace A2 hole + construction-time-only admissibility,
both deferred with an explicit guard obligation on the serving-wiring PR) /
drift (type shapes are a consistent refinement of ADR-0222 §3; one non-gating
ADR note filed). Global red-line ledger: all green.
* feat(determine): one-hop sound relational entailment — inverse/converse + symmetric
Mastery-v2 Step 3 lead capability (core). DETERMINE could perceive relational
structure (16 predicates, breadth-complete) but could not derive the simplest
entailed relational facts — it read only the stored direction. This adds two
SOUND one-hop rules that read a stored edge in its other lawful direction:
INVERSE/converse greater_than(a,b) <= told less_than(b,a)
SYMMETRIC sibling_of(b,a) <= told sibling_of(a,b)
Strictly scoped (per review): OPEN-WORLD (asserts only True, never False — the
answer=False path stays unbuilt, INV-30's firewall holds), ONE hop (NO transitive
chaining), DECLARED rules only. Ontology/metadata-driven, not prose intuition:
- generate/meaning_graph/relational.py: declarative algebra tables — _INVERSE_PAIRS
(the converse edges; the pack carries no inverse metadata) + INVERSE_OF (derived,
an involution) + SYMMETRIC_PREDICATES (mirrors the pack's graph.edge.symmetric tag).
load_relational_pack_symmetric() reads the pack ontology; a test pins the constant
equal to it (no silent divergence).
- generate/determine/determine.py: _relational_one_hop() between direct entailment
and transitive subsumption; new Determined.rule provenance field (direct/inverse/
symmetric/subsumption) — replay-safe (render reads only basis; trace hashes surface).
wrong=0 confuser block proves the rule cannot over-fire: less_than is not
self-inverse, sibling_of does not imply parent_of, greater_than does not imply
equal_to, NO transitive chain (direct or through-inverse), and no answer=False is
ever emitted. An obsolete pin (test_symmetric_converse_is_not_faked, which asserted
the pre-rule direct-only floor) is updated to the new sound behavior and a preserved
asymmetric-converse bite.
Tests: test_determine_relational_inference.py (13, the capability contract) +
updated test_relational_reader.py. Broad relational/determine/grounding +
capability_index baseline sweep: 114 green; baseline digest UNCHANGED (this is a
determination capability; the comprehension lanes are untouched).
REMAINING for the full lead PR (next): the measurement lane — an independent-oracle
evals/relational_inference lane + a capability_index adapter + baseline re-freeze
(breadth 9->10, wrong_total still 0), so the capability registers on the yardstick.
INTEGRATION NOTE (cross-PR): this adds 2 Determined() construction sites (now 4:
direct/inverse/symmetric/subsumption, ALL answer=True). When rebased onto main with
INV-30 (PR #770), update INV-30's test_determine_construction_sites_are_visible count
2 -> 4 and confirm all four assert True. Merge order: #770 -> this.
* feat(capability-index): relational-inference lane — breadth 9->10, wrong=0
Mastery-v2 Step 3 lead, measurement half. Puts the one-hop relational-inference
capability ON the capability index with an independent-oracle lane:
- evals/relational_inference/v1/: cases.jsonl (13 positive: 8 inverse + 5 symmetric,
authored from the relation algebra INDEPENDENTLY of determine/relational per
INV-25/27), refusals.jsonl (8 confusers that MUST refuse), provenance.md (incl. the
honest overlaps_event reader-surface coverage gap).
- evals/comprehension/relational_inference_runner.py: told fact(s) -> determine(query)
vs gold; refusal = coverage miss, disagreement = wrong (structurally 0 on positives).
- evals/capability_index/adapters.py: comprehension_relational_inference_result added
to ADAPTERS.
- baseline.json re-frozen: breadth 9 -> 10, capability_score 0.94403 -> 0.949483,
wrong_total still 0, digest deliberately changed (35dea2b2...).
- tests/test_relational_inference_lane.py: SHA-pinned gold, positive wrong=0 +
coverage>0, and the confuser wrong=0 BITE (every confuser must refuse).
Also reconciles INV-30 (now in main via #770): determine.py grew from 2 to 3
Determined() construction sites (direct, the shared relational one-hop constructor,
transitive subsumption) — ALL answer=True. test_determine_construction_sites_are_visible
updated 2 -> 3 (correcting the prior commit note's overcount of 4; inverse and symmetric
share the single _relational_determined constructor, so it is ONE new site).
Also fixes a .gitignore gap: ADR-0219 gen-dir checkpoints (engine_state/current,
engine_state/gen-*/) were not ignored (only the old flat engine_state/*.json patterns
were), so runtime checkpoints could be committed by accident.
Verification: new lane 13/0/0 coverage 1.0; capability_baseline digest matches the
re-freeze; INV-30 + architectural invariants green; smoke 99/99.
* docs+test: reconcile stale relational-inference docstrings; assert rule provenance (review #775)
Addresses two review-requested cleanups on #775:
1. Stale docstrings. generate/meaning_graph/relational.py said the symmetric converse
is "a sound-but-incomplete refusal at DETERMINE" and there is "NO transitive/
symmetric/rule inference"; generate/determine/determine.py said "symmetric-converse
questions are Undetermined", "no transitive/symmetric/rule inference", and "asserts
only answer=True on a direct hit". All false after the one-hop relational algebra
landed. Updated: the reader does direct-reading only; DETERMINE applies declared
one-hop inverse/converse + pack-declared symmetric (plus the existing member/subset
subsumption), still open-world / never answer=False; transitive relational closure,
negation, and closed-world falsehood remain out of scope.
2. Rule-provenance gold now meaningful. The relational_inference runner compared only
(answer, predicate, subject, object), ignoring res.rule though the gold carries
"rule": "inverse"/"symmetric". Added res.rule to the got/gold tuple so a "right
answer via the wrong rule path" can no longer pass silently. Lane still 13/0/0;
baseline counts (and digest) unchanged.
Verification: runner 13/0/0; lane + capability_baseline + unit + INV-30 green (22).
Adds the one missing mechanical firewall in the learning-boundary set: the
open-world determination gear (generate/determine/determine.py) may construct
only Determined(answer=True) or refuse (Undetermined) — it can never assert
answer=False. Absence never refutes (open-world); a False from absence would be
an unsound, wrong=0-class assertion. The planned DEEPEN/Step-2b closed-world
entailed-negation capability (ProofWriter-CWA / FOLIO two-sided labels) must use
a distinct closed-world result type and entry point, so this invariant keeps it
lane-scoped by construction rather than by reviewer vigilance.
INV-30 follows the existing suite's Schema-Defined-Proof-Obligation discipline:
- test_no_determined_asserts_false — the firewall (project-wide AST scan)
- test_detector_is_non_vacuous — proves it FAILS on injected answer=False
- test_detector_ignores_true_and_reads — proves no false positives
- test_determine_construction_sites_are_visible — proves the scan is not blind
Doctrine: CLAUDE.md Teaching Safety + docs/runtime_contracts.md now state the
corrected typed-learning boundary (durable=reviewed/proof-carrying;
provisional=autonomous iff typed/isolated/replayable/non-masquerading) and cite
the enforcing invariants INV-21/22/23/24/29/30, including the honest wrinkle that
ADR-0148 promote_eligible_entries is a second, opt-in, default-off COHERENT path.
No source code changed; firewall is additive.
Full architectural invariant suite: 65/65 green.
Close the deferred Vault item 4: a read-only endpoint proving a selected
vault entry is recallable by CORE's actual exact CGA machinery, surfaced
in the entry inspector.
Backend (read-only, cold-persisted only):
- GET /vault/entries/{index}/recall rehydrates the persisted VaultStore
(VaultStore.from_dict — bit-exact versors, no reprojection) and runs the
real VaultStore.recall using the entry's own stored versor as the query.
Exact cga_inner scan — never ANN / cosine / approximate.
- recall's +inf exact-self-match sentinel never crosses the boundary: the
genuine finite cga_inner is reported plus an exact_self_match flag. The
raw versor never leaves the engine — only content-addressed digests.
- Trust boundary: caller-controlled index -> 404 (out of range / non-int);
absent persisted snapshot -> 501. The file is never written; the live
runtime is never touched; recall is deterministic over persisted bytes.
Frontend:
- "Exact CGA Recall" inspector panel, collapsed by default so the read is
opt-in (the query hook only mounts on expand). Copy says "exact CGA
recall" / cga_inner — never similarity / relevance / score / ANN /
cosine. Honestly surfaces that a byte-identical self-match is promoted
ahead of metric ranking (CGA null-vector self inner-product ~0).
INV-24: register workbench/readers.py in VAULT_RECALL_SITES as
EVIDENCE_TELEMETRY (operator inspection evidence, not claim-shaping), and
tighten the recall-site detector to recognise VaultStore.from_dict factory
bindings so the obligation is real rather than silently bypassed.
Tests: backend 501/404/self-recall/determinism/no-mutation/JSON-safety +
API status codes; frontend collapsed-doctrine + expanded self-recall
evidence. Full workbench suite (192) + architectural invariants (61) +
vault-touching vitest (70) all green.
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.
INV-29 is the load-bearing contribution of #693, so its detector must match
its claim. The assignment-only scan missed common write indirections; the
widened _status_transition_writes (renamed from _status_assignment_targets)
now also catches:
- m.update({"epistemic_status": ...}) / update(epistemic_status=...) /
update(**{...}) / update(dict(epistemic_status=...))
- m.setdefault("epistemic_status", ...)
- bound and unbound __setitem__ with the literal key
- setattr(entry, "epistemic_status", ...)
- writes hidden in tuple-unpacking assignment targets
29b now proves all 13 shapes are flagged (per-shape, so one regression names
itself); new 29b' proves reads, other keys, and dict-literal construction do
NOT flag (false positives would train reflexive allowlisting). Honest scope
note added: variable keys / exec / C-level aliasing are statically
undetectable and belong to review.
Pre-scan confirmed zero production call-shape writes exist, so the widened
detector flags nothing new; ALLOWED_STATUS_TRANSITION_SITES stays
{"vault/store.py"}. No runtime change; ADR-0218 still Proposed.
Validation:
- tests/test_architectural_invariants.py: 61 passed
- tests/test_proof_carrying_promotion_obligations.py: 3 passed, 6 xfailed
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).
REALIZE roadmap Step 3, slice R0: the boundary that turns comprehension from an
EVAL ARTIFACT into accumulating living knowledge. A comprehended declarative fact is
integrated into the held self as a structured vault entry (versor, metadata) — NOT a
new store — so it inherits exact cga_inner recall, EpistemicStatus stamping, and
bit-exact Shape B+ persistence for free. Scope: docs/analysis/REALIZE-scope-2026-06-06.md.
generate/realize/realize.py — realize_comprehension(Comprehension|Refusal, ctx) ->
Realized(record, created) | NotRealized(reason):
- eligibility: a Comprehension (not Refusal) with NO queries and EXACTLY ONE
non-negated relation whose subject grounds IN-VOCABULARY. Everything else is a
typed NotRealized with zero vault writes (wrong=0).
- in-vocab-subject only: OOV grounding is non-deterministic across reboots (an
empirically-confirmed substrate gap), so OOV subjects are declined in R0.
- SPECULATIVE always (COHERENT is never a default — ADR-0021); provenance via
MeaningSpan source_span + structure_canonical; content_hash + replay_hash via
canonical-JSON SHA-256 (floats forbidden).
- idempotency: dedup by content_hash within the session (exact-canonical,
span-inclusive — safe direction only, never drops a distinct fact).
- durable schema admits a 2nd substrate later via structure_kind/structure_canonical.
- stores via the existing VaultStore.store path: no new embedder, no normalization
(closure stays algebra/versor.py), no parallel learning path.
Explicitly OUT of R0: COHERENT promotion, teaching-loop proposals, trace-folding,
relation-space recall, the arithmetic/binding_graph path.
tests/test_realize_r0.py (10) — eligibility (refusal/query/multi-relation/OOV all
write nothing); record fields; idempotency (re-told fact doesn't grow the vault);
SPECULATIVE status firewall (recall(min_status=COHERENT) excludes it); the
falsifiable exit gate (told -> realize -> snapshot -> reboot -> recall: byte-exact
content_hash + score + versor bytes, speculative, versor_condition<1e-6); and
replay_hash re-derivable after reboot. Gate verified to BITE (COHERENT default,
refusal-writes, reprojection-on-load all fail it).
INV-21: generate/realize/realize.py added to ALLOWED_VAULT_WRITERS — a sanctioned
writer (same VaultStore.store path, SPECULATIVE default, nothing on Refusal).
Adversarially reviewed (3 lenses: invariants/wrong0/honesty, determinism/boundary,
scope/adjustments) — no critical/high/medium findings; low/nit honesty wrinkles
folded (state-dependent-placement wording, span-inclusive-dedup note, direct
versor-bytes gate assert, replay_hash re-derivation test). 10 R0 + 90 smoke green;
lane SHAs 8/9 (sole miss = public_demo env flake; deductive_logic + math_teaching
unchanged -> no GSM8K coupling).
The binding-graph's FIRST comprehension consumer (doctrine-aligned: quantities live
in binding_graph, NOT the MeaningGraph). generate/quantitative_comprehension.py
reads arithmetic prose into SymbolBinding/BoundFact/BoundEquation and runs the REAL
check_admissibility (shell -> verify -> rebuild with the actual UnitProof) — there
is NO stamped "admitted": an equation is admitted only if its operand units verify.
Then to_relational_metric projects the binding-graph to the independent
relational_metric oracle for the verdict.
Templates (digits only; non-digit quantity REFUSES):
"<X> has <N> <unit>" -> BoundFact(X = N)
"<Y> has <N> more <unit> than <X>" -> BoundEquation(Y = X + N) op=add
"<Y> has <N> fewer <unit> than <X>" -> BoundEquation(Y = X - N) op=subtract
"How many <unit> does <Y> have" -> ask Y
"How many <unit> do <X> and <Y> have"-> total = X + Y; ask total
Unit modelling (honest, not faked): a noun the closed en_units_v1 pack knows is
used verbatim (dollars -> dollar/money); an UNKNOWN sortal noun (stickers, coins)
is a count of discrete objects -> the existing 'item' lemma (dimension count). So
admissibility stays a REAL check: count+count admits, count+money (a mixed-unit
sum) REFUSES with unit_mismatch — verified to bite.
comprehension_relational_metric: 15/15 wrong=0 (full coverage). Located OUTSIDE
generate/meaning_graph (it targets binding_graph, not the MeaningGraph) so INV-28
neutrality stays intact; oracle imports none of the SUT (new INV-25 lane).
Capability index breadth 7->8, score 0.928622 -> 0.937258, wrong_total 0, digest
50e0675b…
Tests: reader templates + count/known-unit modelling + admissibility-bite (mixed
unit refuses) + non-digit refusal; end-to-end full-coverage wrong=0; arithmetic
added to the structure-preservation generative panel (projected relations+query ==
ground truth); capability breadth 7->8; INV-25 arithmetic lane. 93 targeted + 90
smoke green; lane SHAs 8/9 (sole miss = public_demo env flake; deductive_logic +
math_teaching unchanged -> no GSM8K coupling).
Addresses the review's hygiene point: the comprehension lanes deserve the same
repo-wide independent-gold + neutrality discipline as the older reasoning lanes.
INV-25 (independent gold): register the four comprehension lanes
(set_membership / syllogism / total_ordering / propositional) so their domain
oracles are statically proven to import NONE of the comprehension organ
(generate.meaning_graph reader + projectors). The gold the reader is scored
against is thereby independent of the reader — the anti-overfit firewall now covers
comprehension, not just the structured-input lanes. All four oracles are clean
(stdlib-only), so the firewall passes.
INV-28 (MeaningGraph neutrality): a new repo-wide invariant mirroring INV-26's
binding-graph neutrality — no generate/meaning_graph module imports
field/algebra/evals/vault/chat/core/sensorium or numpy. The MeaningGraph is the new
neutral meeting point where prose-read structure projects into independent oracles;
it earns the same firewall. numpy is forbidden too: Path β reads structure
SYMBOLICALLY and quantities are the binding-graph's domain, not the MeaningGraph's.
Non-vacuity test included (the predicate flags a module known to import the field
engine).
Tests-only. 56 architectural-invariant tests pass (was 53 + 3 new INV-28 +
4 INV-25 lanes wired into the existing oracle-firewall test).
Measurement #1 of the field-reasoner falsifiable experiment: does the CL(4,1) field,
given an honest metric encoding, read forward-substitutable quantitative-relational
problems from TEXT with wrong==0? It does — 14/15 correct, 0 wrong, 1 refused
(precision ceiling), scored against an independent arithmetic oracle.
- generate/relational_field_reader.py: reads problem text into conformal points on
the e1 number line; additive/part-whole relations are conformal TRANSLATOR versors
(versor_apply(T_delta, embed[x]) == embed[x+delta], exact); the answer reads back
by projective dehomogenization. Refusal-first: fences multiplicative/ratio (the
sign/orientation-blind cases), the precision ceiling, non-forward-substitutable
references, negatives. A per-step exactness self-check turns any f64 translator
drift into a refusal (precision_drift) — it NEVER commits a wrong integer. Its
parser is an independent reimplementation importing no generate.derivation/math_*.
- evals/relational_metric/: independent arithmetic oracle (computes gold from the
STRUCTURE, shares no code with the reader), 15-case fixture, and a runner that
enforces gold integrity + wrong==0.
- INV-25: relational_metric registered in INDEPENDENT_GOLD_LANES (oracle proven
code-disjoint from the field reader and the algebra engine). The independently
golded panel is now three domains: deductive, dimensional, relational-metric.
Green: smoke 87, 53 architectural invariants, 16 new tests; deductive + dimensional
lanes unperturbed (wrong=0).
Phase 0 of the field-reasoner wedge — net hardening regardless of the
experiment's outcome.
- algebra/cga.py: embed_point gains a dtype kwarg (f32 default byte-unchanged;
cl41.geometric_product already preserves f64) + read_scalar_e1 projective
dehomogenization read-back (weight-invariant; correct for dilations, where a
raw distance-from-origin is wrong) + EMBED_EXACT_MAX pinned magnitude ceiling.
f32 silently collapsed integer coordinates past ~1e4.
- core/reasoning/evidence.py: verify_tier2_agreement now keys independence on a
reader_lineage pathway token (refuses SAME_READER_LINEAGE), replacing the
label-only len(set(signatures))<2 check a single reader could satisfy by
relabeling. reader_lineage is excluded from canonical serialization, so the
entailment trace_hash is unchanged.
- tests INV-27: transitive reader-disjointness over TIER2_READER_PATHWAYS makes
the lineage check load-bearing (distinct lineage => proven import-disjoint
pathway). The two seeded readers share zero transitive first-party modules.
Green: smoke 87, algebra 82, cognition 121, 53 architectural invariants,
reasoning/deductive/r1 50; 16 new f64-exactness tests; zero regressions.
The first non-GSM8K consumer of the binding-graph interlingua's unit algebra as a
load-bearing reasoner: given two units and an operation, decide the result's
dimension. SUT = generate.binding_graph.units; gold = evals/dimensional/oracle.py,
a genuinely INDEPENDENT dimensional reasoner (own unit->base-exponent table, own
exponent arithmetic, own canonical-string renderer; shares no code with the SUT).
12 cases (area / speed / wage / mass-density / dimensionless / 2 refused) gated by
SUT == oracle == gold (wrong=0). Registered in INV-25's INDEPENDENT_GOLD_LANES,
proving the independent-gold discipline generalizes to a SECOND oracle.
This is the 3rd structurally-distinct golded domain (logic / grounding / dimensional)
— the anti-overfit >=2-domain panel is now real, and the interlingua is load-bearing
beyond GSM8K.
Declares SemanticSymbolicBindingGraph the universal problem-structure interlingua
(the corpus callosum where the geometric field and symbolic ROBDD decodings meet
and must agree). INV-26 enforces that neutrality structurally: 26a no binding-graph
module imports field/algebra/eval/vault/chat/core/sensorium; 26b the core imports
no domain reader (only allowlisted bridges adapter/question_target may); 26c proven
non-vacuous (flags pipeline.py's field import + the adapter's domain import).
Amends the plan doc with the structurally-diverse checkable panel (logic/grounding/
dimensional/execution/constraint, each with independent gold) and the 'a capability
change must move >=2 structurally-distinct domains or it is suspected overfitting'
rule, woven in from Phase 2 — the anti-overfit instrument the train_sample breach
proved we need.
Validated: architectural invariants 49 + binding_graph model = 118 passed.
INV-25 makes the GSM8K lesson structural: no capability claim is valid unless
its gold is computed by a procedure sharing no code with the system under test.
Three meaningfully-failing checks (proven able to fail): 25a oracle imports no
SUT module (AST); 25b every committed deductive gold is reproduced by the
independent oracle AND matched by the engine; 25c an unsound engine disagrees
on committed cases.
SHA-pin the deductive lane (deductive_logic_v1, dev+holdout+external 716/716,
wrong=0, refused=0) via a deterministic --report writer + run_as_module (the
lane dir's local generate.py shadows the package in script mode) + CLAIMS regen.
Fix drift the review surfaced: contract.md + pivot doc claimed an 8,000/7,340
fuzz and an 'external mirror' -> corrected to the real gated 3,000-case fuzz
(2,796 definite) and 'hand-authored, NOT a published-benchmark mirror'; pivot
doc GSM8K holdout 0->5 (all 5 are R1 reconstruction; composer scored 0).
Validated: smoke 78, deductive 23, proof 29, invariants 44, lane-sha+claims 9.
Both INV-02/INV-21/INV-24 scan functions walked into .claude/worktrees/
and found vault recall/write callsites in the stale
step-3-submission-invariants checkout, producing 3 false failures.
Fix: add '.claude' to the os.walk exclusion set (INV-02) and to
EXCLUDED_DIRS (INV-21/INV-24). Defensive against any future worktree
that agents create under .claude/worktrees/.
Also pruned 58 stale worktree git-dir entries via git worktree prune
and removed the step-3-submission-invariants worktree directory.
Smoke suite: 67/67 passed.
The issue #300 regression test calls normalize_to_versor() directly
to verify its closure contract — identical justification to
test_versor_closure.py. Without the allowlist entry, INV-02 fails
in CI on every PR rebased on top of the #312 fix.

Two follow-up fixes from end-of-session verification of recent merges:
1. core/cli.py — wire `core contemplation` subcommand
PR #55 + #58 added the contemplation CLI at python -m core.contemplation
but never registered it under the `core` umbrella command, so
`core --help` didn't show it. Adds a subparser mirroring the existing
pattern (chat/test/check/.../doctor) that delegates to the existing
core.contemplation.__main__:main() — no duplication of arg parsing.
Surface preserved verbatim: reports (positional, 1+), --lane
{frontier_compare, contradiction_detection}, --pack-id, --note,
--report, --sink-root.
2. tests/test_architectural_invariants.py — restore INV-02 allowlist
PR #57's evals/lab/phi_separation_probe.py imports normalize_to_versor
for construction-time experimental rotor + embedding work, which
triggered INV-02's AST-scan failure (the test enforces that
normalize_to_versor is only called from a small allowed file set).
evals/lab/ is research-only, never imported by runtime — adding the
probe to allowed_files doesn't weaken the runtime invariant the
test enforces.

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).
Closes the two skipped null-preservation tests and the architectural
gap behind them. In CGA, null vectors represent Euclidean points;
under a conformal transformation a point must map to a point —
applying a versor sandwich to a null vector must preserve null
property. The previous implementation forced everything onto the
unit-versor shell, which is correct for field-state propagation but
wrong for geometric point input.
Implementation
- algebra/versor.py: new `_input_is_null(F)` checks `cga_inner(F,F) ≈ 0`;
`versor_apply` routes null inputs around `_close_applied_versor`
and returns the raw sandwich V·F·rev(V), which algebraically
preserves null property. Non-null inputs unchanged.
- core-rs/src/versor.rs: `versor_apply_closed_f64` gains the same
null-check branch via `input_is_null_f64`. ADR-0020 parity
preserved (8/8 versor_apply bit-identity tests still pass).
Test changes
- tests/test_architectural_invariants.py::TestINV06NullConePreservation::
test_versor_apply_preserves_null_property — un-skipped, passes.
- tests/test_rust_backend.py::test_rust_versor_apply_preserves_null_vectors
— un-skipped, passes.
- tests/test_versor_closure.py::test_versor_apply_closes_null_like_field_
results_for_runtime_contract — renamed to
test_versor_apply_preserves_null_property_for_null_inputs and
rewritten to assert the now-correct semantics (null in → null out).
The old contract over-specified closure for null inputs and
contradicted the architectural invariant; that's what kept the
invariant test skipped.
Stale gap docs updated
- inference_closure / cross_domain_transfer / multi_step_reasoning
gaps.md now lead with a resolution block: lanes pass at 100% on
both splits after the typed operators (transitive_walk,
multi_relation_walk, path_recall in generate/operators.py) +
pipeline wiring (_maybe_transitive_walk + _fold_walk_into_surface)
landed. The historic findings are preserved below for traceability.
- compositionality gaps.md: partial resolution — recall up from
6.25% to 68.75%; overall_pass True; residual ~30% miss requires
a relation-aware `compose_relations` operator (v2 follow-on).
Lane health unchanged: algebra 132, smoke 55, runtime 19, teaching 17,
packs 6, cognition 103. Cognition eval 100%. Four formerly-"blocked"
reasoning lanes confirmed 100% / overall_pass=True end-to-end.
Remove shelved identity/drive tests that existed to justify premature
persona wiring, and update remaining tests to match the current runtime
contract: empty vault triggers unknown_domain gate on first turn, versor_apply
always closes to unit versor, and null-cone preservation is deferred to an
explicit geometry API.
562 passed, 4 skipped, 0 failed.
Key issues fixed:
- `CORE_BACKEND=numpy` was ignored, so tests mixed Python CGA embedding with Rust metric behavior.
- Dense construction seeds were being rejected by strict `unitize_versor()`, while sparse dirty inputs still needed to fail closed.
- Holonomy needed a construction-boundary path for raw/dense vocab fixtures and rare null final accumulators.
- Proposition storage polluted vault recall by storing the live field instead of the proposition’s subject versor.
- Dialogue qualitative frames rendered the same surface as assertive copular frames.
- Repeated session prompts could collapse into the same deterministic response path.
- Two proof fixtures were stale: one hand-built a non-null “null” vector, and one alignment proof omitted the English “with” anchor used by the resonance proof.
Verification:
`CORE_BACKEND=numpy CORE_STRICT_MLX_ON_APPLE=0 uv run core test -- -q`
Result: `277 passed in 59.52s`
algebra/rotor.py and persona/motor.py were calling normalize_to_versor()
which is the gate-only injection primitive. Both are construction-time
sites (building rotors and motors from raw arrays), so the correct call
is unitize_versor().
Also tightens TestINV02 to scan for normalize_to_versor violations only —
unitize_versor has its own legitimate call sites and is not under the
same single-site restriction. Adds a new TestINV02b that verifies
unitize_versor is NOT called inside propagation, generation, or vault
recall paths.
Fixes: INV-02 architectural invariant test failure.
