Completes the recommended fix in docs/issues/default-engine-state-test-hygiene.md.
The root conftest autouse fixture already redirected engine_state._DEFAULT_DIR
per test (the in-process half, req #1); this adds the two missing halves:
- monkeypatch.setenv("CORE_ENGINE_STATE_DIR", isolated) so subprocess / CLI
tests that re-import engine_state in a child process inherit the same
isolation (req #2). A child that sets its own env still overrides and wins.
- @pytest.mark.uses_default_engine_state opt-out (registered in pyproject.toml)
for tests that intentionally exercise the real process-default dir (req #3).
Adds tests/test_conftest_engine_state_isolation.py: non-vacuous proof that each
half fires and that the marker opts out; each assertion fails if its half is
removed (CLAUDE.md "Schema-Defined Proof Obligations").
Validation: full serial baseline on origin/main (95a06a20) = 38 pre-existing
reds (21 failed + 17 error). The only new behavior over baseline is the setenv,
whose sole live effect is child processes; a full re-run of the subprocess/CLI
blast radius shows zero new failures, and the documented test_achat
identity-continuity warning is gone. Does NOT add -n auto adoption or the
fresh-env-dict subprocess hermeticity fix (tracked separately).
* feat(determine): add transitive strict-order relational inference
Add sound transitive closure for declared strict-order relational predicates —
less_than, greater_than, before_event, after_event, and ONLY these. A query
p(a, c) determines True when a same-predicate chain p(a, b), p(b, c), ... over the
predicate's OWN realized edges is found (BFS reachability) and the proof_chain ROBDD
verifies the transitive entailment (search-then-verify, through the UNCHANGED
evaluate_entailment via a new lower_transitive_chain). Mirrors _determine_subsumption.
Scope / firewall:
- TRANSITIVE_PREDICATES is closed and default-off; sibling_of, parent_of,
left_of/right_of, inside_of, during_event, overlaps_event are EXCLUDED.
- Same-predicate edges only — no transitive-through-inverse, no cross-predicate
(triple firewall: recall filter + lowering re-reject + ROBDD re-verify).
- Open-world: asserts only answer=True via the shared _relational_determined
surface (rule="transitive"), so INV-30 stays at exactly 3 Determined sites and
no answer=False is added. One-hop inverse/symmetric (#775) is unchanged.
FrameVerdict / closed-world (ADR-0222) is untouched.
wrong=0 bite (unit + lane + independent oracle): non-transitive-predicate chains,
non-admitted spatial chains, mixed-predicate chains, disjoint chains, reflexive
cycles, and inverse+transitive composition all REFUSE.
Measurement: new evals/relational_transitive lane with an INDEPENDENT BFS
transitive-closure oracle (imports no engine module; INV-25/27), cross-checked both
directions (positives oracle-True, confusers oracle-False). Capability-index breadth
10 -> 11, wrong_total 0, deterministic digest re-frozen.
Cross-PR reconcile: migrated the one-hop confuser rinf-ref-001 (a less_than chain,
which now correctly determines transitively) to a B2 positive; repurposed its unit
test to a non-transitive parent_of chain; corrected a pre-existing stale breadth==9
assertion (#775 added a 10th domain but never updated test_capability_index).
Verified in the worktree: determine + transitive/one-hop lanes + capability
baseline/index + ProofWriter-OWA floor + INV-30/29/21/02 + full smoke — all green.
A 3-skeptic read-only adversarial review found no wrong=0 leak.
* test(determine): B2 hardening — TRANSITIVE_PREDICATES pin + lower_transitive defensive + budget
Add the required B2 hardening tests before merge:
- test_transitive_predicates_closed_and_excludes: the table is EXACTLY
{less_than, greater_than, before_event, after_event}, every member is in
RELATIONAL_PREDICATES, and every deliberately-excluded predicate (sibling_of,
spouse_of, parent_of, child_of, left_of, right_of, inside_of, during_event,
overlaps_event) is explicitly absent. (Closes the gap where relational.py's
comment claimed this test existed but it did not.)
- tests/test_composition_lower_transitive.py: direct defensive tests on
lower_transitive_chain — empty path, mislabeled (cross-predicate) edge, wrong
arity, non-contiguous path, and path-not-reaching-target all lower to None
(refuse); plus exact 2-hop and 3-hop theory pins.
- test_edge_budget_exhaustion_refuses: above _TRANSITIVE_EDGE_BUDGET the transitive
search declines (a safe coverage refusal), never proves.
* feat(eval): ProofWriter-OWA refusal-floor lane (B1) — independent oracle, measure-only
Mastery-v2 Step-3 Brief 1. Proves the open-world soundness floor: determine() never
asserts a query True when the open-world truth is Unknown or False. Hardens
"unknown != false" before the transitive-chain (B2) and closed-world (B4) work can
stress it.
- evals/proofwriter_owa/oracle.py: a SEPARATE minimal OWA label oracle (its own parser
+ reasoner + inverse/symmetric tables), importing NONE of determine, comprehend/
MeaningGraph realization, or production predicate-entailment helpers (INV-25/27 — the
gold producer is disjoint from the solver). Grammar: member/subset/is-a closure,
explicit negation (No X is a Y -> disjointness, the source of gold-False), and #775
inverse/symmetric ONE-HOP relational rules. No transitive relational chains.
- evals/proofwriter_owa/fixtures.jsonl: 19 hand-authored ProofWriter-OWA-style items
(9 True / 7 Unknown / 3 False), SHA-pinned. Gold computed by the oracle; the fixture's
hand-authored `expected` pins the oracle (so the oracle is itself verified).
- evals/proofwriter_owa/score.py: runs the production path (comprehend/comprehend_relational
-> realize -> determine) vs the oracle gold; wrong = determine asserted True on a non-True
gold.
- tests/test_proofwriter_owa_lane.py: SHA pin; oracle==expected; wrong==0; every
serving_support gold-True determines True (no coverage gaps); no answer=False (INV-30).
Result: 19 items -> 9 correct (all serving_support True), 10 refused (Unknown/False),
0 wrong. Measure-only: no engine code touched; deliberately NOT a capability-index domain
(a refusal floor has low coverage and would drag coverage_geomean). INV-30 green; smoke 99/99.
Note: no live ProofWriter dataset access in this environment, so items are hand-authored
in OWA style (provenance.md cites ProofWriter V2020.12.3 / arXiv:2012.13048 for semantics,
attribution only) — but the GOLD is oracle-computed and verified, not hand-asserted.
* harden(eval): OWA lane CLI fails on coverage_gaps too (review #779)
score.py::main() exited nonzero only on wrong>0; it now ALSO exits nonzero when
coverage_gaps is non-empty (serving-supported gold-True items that refused), matching
the acceptance rule the tests already enforce and the module docstring. Both failure
modes print to stderr; exit is 1 if either fires. Verified non-vacuously (injected gap
-> exit 1). Lane test 5/5 green.
The two Gemini robustness nits raced the #774 merge: the patch landed on the
branch after GitHub had merged the pre-patch head, so main shipped the
architecture without the migration-input hardening. This re-lands ONLY the
robustness fixes — no identity-semantics change.
- chat/runtime.py: parse identity_scheme with try/except (TypeError, ValueError)
-> fallback to legacy scheme 1; revision str(... or '') so a null becomes ''
(unverifiable -> conservative DIVERGED), not the literal 'None'.
- workbench/readers.py: stored_revision=written_at_revision or '' so a None
revision is handled identically by the shared reconcile helper.
- tests: malformed identity_scheme does not crash the load guard (migrates);
reader falls back to legacy on malformed scheme; reader missing revision is a
conservative break.
Verified: 50 identity/migration/reader tests pass. No lane/serving path touched.
* 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).
Removes code_revision from the engine-identity hash: engine_identity is now the
sha256 of the 5 ratified packs ONLY. The build revision is provenance (the
manifest's written_at_revision), not identity — so a behavior-neutral rebuild is
the SAME identity and the always-on daemon no longer flag-day strict-breaks on
every commit (the ADR-0220 defect).
Core:
- core/engine_identity.py: ratified_substrate/compute_engine_identity drop the
git_revision arg (packs-only); add compute_legacy_engine_identity (reproduces
the pre-split packs+rev hash, for migration verification), ENGINE_IDENTITY_SCHEME=2,
IdentityReconciliation enum, and reconcile_loaded_identity — the single source of
truth for the runtime guard AND the workbench reader.
- chat/runtime.py: the load guard reconciles via scheme. Current scheme -> direct
packs-only compare. Legacy (code_revision-folded) stamp -> a VERIFYING migration:
reconstruct the legacy hash from the persisted written_at_revision; a match proves
packs unchanged (warn + re-stamp, resume, no break) — a mismatch means the packs
genuinely changed (DIVERGED -> strict-refuse). Preserves 'distinct packs => refuse'.
- engine_state/save_manifest: stamp identity_scheme alongside engine_identity
(additive-optional; no schema_version bump).
- workbench/readers.py: continuity reader uses the same reconcile (no phantom break
on legacy checkpoints). cli.py break message reworded (packs, not 'build revision').
Callsite cleanup: drop the now-unused git_revision arg + imports across
always_on.py, evals/l10_always_on/runner.py, workbench/readers.py.
Tests:
- test_identity_provenance_split.py (new): 5 reconcile unit proofs + 3 runtime
integration proofs incl. the wrong=identity defense (legacy stamp of DIFFERENT
packs still strict-refuses) and the re-stamp migration.
- test_engine_identity.py: invert the code-revision test (rev no longer changes
identity); assert the substrate is packs-only.
- Restore 3 lineage tests silently red since ADR-0219 (flat-path _manifest helper
now resolves the gen-dir).
- Update remaining callsites/monkeypatches for the new signature.
Hygiene: .gitignore now covers the ADR-0219 gen-dir runtime files
(current, gen-*/, session_state.json, proposals.jsonl).
Verified: 59 identity/migration/lineage/workbench + 32 L10 + 76 invariants/cli +
34 smoke pass; serving lane SHAs unchanged (no derivation/reliability_gate touch).
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.
* feat(cli): always-on --engine-state PATH + safe identity-break recovery (ADR-0220 PR B)
Operator ergonomics only — no identity-hashing, strict_identity_continuity, or
manifest-schema change (those are gated on ADR-0220 ratification, PR C).
- core always-on --engine-state PATH: surface the existing per-life state-root
concept. run_daemon already accepts engine_state_path; cmd_always_on now
threads the flag through (default None -> $CORE_ENGINE_STATE_DIR / in-repo dir).
- _always_on_identity_break_message: replace the terse IdentityContinuityError
text with revision-aware recovery guidance (reads written_at_revision so
'git checkout <rev>' is copy-pasteable; offers --engine-state and an in-place
clear-runtime-files path). Safe by construction: never suggests mv/rm of the
engine_state dir, which under the default IS the tracked Python package.
- Suppress ADR-0157's revision-mismatch warning while the formatter reads the
manifest (message builder, not a load path).
- Tests: flag default/parse, threading to run_daemon, message is safe +
revision-aware + placeholder-on-no-manifest.
* fix(cli): fall back to <engine_state_dir> placeholder when state dir unresolvable
Gemini review nit on #772: if EngineStateStore construction fails AND no
--engine-state was given, state_dir stayed None and the recovery message printed
a bare 'None' as the dir to clear. Fall back to '<engine_state_dir>'. Adds a test
that forces the store-resolution exception path, and guards the no-manifest test
against 'None' leaking into the message.
Adds empirical coverage of the three ADR-0219 checkpoint sub-steps where
a process kill can occur: PARTIAL_GEN (gen dir exists but partially written),
FULL_GEN_BEFORE_SWAP (all four files written but current pointer not yet swapped),
and AFTER_SWAP (clean-commit control case, already covered by rec_a/rec_b).
For each of the two non-trivial cut-points the harness:
1. runs a probe soak to commit reboot_turn turns,
2. injects the corresponding orphan shape,
3. reads the on-disk manifest to confirm the loader follows `current` and reads
the committed generation (not the orphan),
4. runs two independent recovery soaks (each injecting the same orphan at the
reboot boundary) and verifies their post-reboot trace_hash tails converge,
5. checks versor_condition < 1e-6 throughout every recovery soak.
New predicate evaluate_p4_arbitrary_interruption (predicates.py) expresses
this as a PredicateOutcome with a CutPointEvidence carrier. It has:
- holds gate: recovered_turn_count == expected (orphan was ignored)
- holds gate: tail_hashes_a == tail_hashes_b (two recoveries converge)
- holds gate: all versor_conditions < ceiling (closure throughout)
- bites gate: tested by four mutation tests (wrong count, diverging tails,
vc violation, empty tails)
contract.md: all spec predicates P1-P5c are now covered (NOT_COVERED is empty).
Per CLAUDE.md schema-as-proof: every predicate gate is verified by a *_bites
mutation test — 9 tests total (3 injection unit, 2 real-soak holds, 4 bites)
all pass in 109s.
Adds W1-T: an observational telemetry leaf for idle_tick's learning flywheel,
modeled on core.cognition.leeway (the B4 precedent). Never gates, refuses,
or alters trace_hash.
New core/cognition/backpressure.py:
BackpressureRecord(pending_proposals, candidate_backlog, cap, headroom,
contemplated_this_tick, created_this_tick, at_fixed_point, did_work)
build_backpressure_record(...) — pure function, resolves ADR-0161 cap from
env (CORE_HITL_PENDING_CAP or 256), derives headroom = max(0, cap-pending),
at_fixed_point = (candidate_backlog==0 and created_this_tick==0).
chat/runtime.py:
IdleTickResult gains backpressure: BackpressureRecord | None = None (always
set on a completed tick).
idle_tick builds the record from counts already computed (pending_proposals,
candidate_backlog, contemplated_count, created, did_work) — no new
computation, no serving-path change.
Appends one JSONL line per tick to engine_state/idle_telemetry.jsonl
(best-effort, never crashes the continuous life; accumulates across all
generations so history survives reboot independently of the checkpoint).
tests/test_idle_backpressure_telemetry.py (16 tests):
- field derivation: headroom, cap, at_fixed_point (holds + bites)
- cap resolution: default 256, env override, invalid env fallback
- firewall proof: trace_hash of a served turn is byte-identical whether
idle_tick ran before it or not (the load-bearing invariant)
- integration: record fields on a fresh runtime; telemetry written to
engine_state dir; history accumulates across ticks
All 16 tests pass. ADR-0161 cap and queue_full control logic untouched.
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.
Adds the P5a recall-precision predicate that was listed as NOT_COVERED in
the L10 continuity lane. Closes the gap in the schema-as-proof discipline
(CLAUDE.md): every predicate must have both a *_holds test (real soak) and
a *_bites mutation test so a passing lane cannot silently miss the violation
it nominally catches.
Changes:
- runner.py: ProbeRecord dataclass + probe_at/verify_probes_at params on
run_soak(). Registers a field state (float32 bytes, matching vault's
_exact_index dtype) at a named turn and recalls it against the vault at a
later turn — including after a reboot, which is the cross-reboot claim.
- predicates.py: evaluate_p5a_recall_precision — fails if any ProbeRecord
has rank=None or rank>top_k, or if no cross-reboot probe was recorded.
- report.py: wires P5a into build_report(); probe registered at turn 1,
verified at reboot_turn+2 (intentionally before the vault's
null_project auto-reproject cycle at store_count=20, which would destroy
all CGA inner-product scores — documented as a real finding, deferred to
a follow-up increment); NOT_COVERED is now empty ().
- contract.md: P5a row in the predicate table + reprojection-boundary
scope note.
- test_l10_continuity.py: 4 tests — holds (real 6-turn soak across reboot)
+ 3 bites (rank=None, no cross-reboot probe, empty probe_records).
Key finding: vault.null_project() fires every vault_reproject_interval=20
stores and produces CGA-orthogonal versors (inner product → 0.0 with the
original), completely destroying both exact-match and ranked recall. This
is a long-horizon vault stability issue, recorded here rather than silently
avoided. The P5a probe window is constrained to the pre-reproject interval
to keep wrong=0 intact while documenting the gap.
Closes the cross-file checkpoint-atomicity gap in ADR-0156. The four
checkpoint files now live in a committed gen-NNNN/ directory; the single
atomic os.replace of a 'current' pointer file is the commit boundary.
A kill before the pointer swap leaves the prior committed generation
intact; a kill after commits the new generation. Unreferenced gen dirs
are ignored. ADR-0156's deferred parent-dir fsync is also closed.
Key changes:
- engine_state/__init__.py: begin_generation() + commit_generation() +
_resolve_dir() for all load_* methods. Flat-layout legacy checkpoints
migrate into gen-0000 on first begin_generation call. GC retains K=2
committed generations.
- chat/runtime.py: checkpoint_engine_state uses the two-phase commit;
finalize_turn_trace_hash no longer writes discovery_candidates outside
the generation sequence (the second unguarded write path is closed).
- evals/l10_continuity/runner.py: _inject_orphan_tmp updated to inject
the two orphan shapes of the generation model.
- tests/test_adr_0219_generation_checkpoint.py: 18 tests, one per
acceptance-gate bullet + biting mutation variant each.
L10 lane: all_gates_pass=true; versor_condition<1e-6 throughout.
Smoke: 95 passed. Runtime: 20 passed.
* feat(l10): autonomous idle frontier-contemplation — the always-on life learns on its own
Frontier survey move #2, path (c): give the always-on idle life a stream of experience via
SYMBOLIC intake (not the afferent→field seam, which is deferred pending a commensurability
ruling — docs/analysis/afferent-field-ingest-scope-2026-06-15.md). The idle heartbeat
converges (idle_tick drains a finite backlog + saturates is-a closure, then does nothing
forever); this makes it autonomously MINE its frontier with no user turn.
Reuse-heavy (the mechanism largely existed): a gated idle pass wires ADR-0080 contemplation
into the always-on loop.
- core/config.py: contemplate_frontier_during_idle (default off → no behavior change).
- chat/runtime.py: idle_tick pass 2b — when on, runs core.contemplation.run_contemplation()
(mines the checked-in frontier-compare reports) and persists a reviewable ContemplationRun
to <engine_state>/contemplation_runs/idle_<substrate_hash>.json. IDEMPOTENT per frontier
(an already-mined frontier is not re-persisted → the life converges, no churn) and MEMOIZED
per session (the static frontier is mined once, not re-read every beat). SPECULATIVE-only
(ADR-0080: ContemplationFinding.__post_init__ RAISES if not SPECULATIVE → wrong=0 by
construction; never ratified here — the HITL path is untouched). IdleTickResult gains
frontier_findings.
- chat/always_on.py: run_continuous did_work + HeartbeatRecord count frontier work, so the
heartbeat/soak convergence (H3) stays honest.
- core/cli.py: `core always-on --contemplate-frontier` (explicit learning-daemon mode) +
honest per-beat log ("+N findings").
Adversarial 3-lens review (wrong=0/convergence, determinism/trust-boundary, test-vacuity)
found 7; fixed the real ones: the MEDIUM torn-write (write_contemplation_run is now atomic
temp+os.replace — the indefinite-uptime daemon expects SIGKILL mid-write, and the skip-guard
would never repair a torn canonical file), the gitignore breadth (contemplation_runs/ at any
engine-state root), the 64-bit filename truncation (full substrate_hash), and the
re-mine-every-beat cost (session memoization). Deferred + documented: the shared
contemplation miner embeds absolute report paths in finding CONTENT — a portability wrinkle
that does NOT affect wrong=0/convergence/soak determinism (those key on the content-only
substrate_hash) and touches shared code + its test surface; a follow-up.
Tests (non-vacuous): 7 — off-by-default (no behavior change), mines-when-enabled,
findings-SPECULATIVE (wrong=0), converges-idempotent, heartbeat-mines-then-converges,
mines-once-per-session (memoization), atomic-no-orphan. 55 idle/contemplation/always-on +
96 invariants/contemplation + 28 smoke green; `core always-on --contemplate-frontier` mines
end-to-end. engine_state contemplation_runs are per-life runtime state (gitignored).
* fix(l10): isolate idle frontier pass + persist frontier_findings (#758)
Three review blockers on the autonomous idle frontier-contemplation pass:
1. Daemon isolation. idle_tick's pass 2b called run_contemplation /
write_contemplation_run bare inside the always-on loop (run_continuous
wraps idle_tick in nothing but an exit-checkpoint finally), so a malformed
frontier report or a transient FS fault would propagate out and KILL the
continuous life. Wrap the optional pass best-effort (the exit-checkpoint
boundary idiom): degrade to 0 findings + RuntimeWarning, leave did_work
untouched, let a later beat retry.
2. Durable did_work explanation. HeartbeatRecord carried frontier_findings
but serialize_report omitted it and AlwaysOnReport had no run total, so
lived_life.json could show did_work=true with facts=0/proposals=0 and no
persisted cause. Persist frontier_findings per-record + total_frontier_findings.
3. Honest HITL claim. The docstring/CLI/config said findings are "reviewable
via the HITL path", but the existing HITL queue + workbench reader scan
<repo>/contemplation/runs while the pass writes <engine_state>/contemplation_runs/.
Narrow the claim to "persisted reviewable artifact, not yet in the HITL
queue" (wiring that discovery is a follow-up).
Tests: 4 new non-vacuous regressions (mining-failure degrade, write-failure
degrade, always-on loop survives frontier failure, lived_life persists
frontier_findings) — all fail against the unpatched pass. 38 L10/always-on/
workbench tests green.
The always-on PROCESS shipped (run_continuous + daemon + CLI), but the claim "it holds
over uptime" was UNFALSIFIED: the existing evals/l10_continuity soak drives the TURN loop
and is disjoint from run_continuous; the daemon path was covered only by ≤5-beat unit
tests. This lane converts "built" → "proven over horizon" for the idle path.
evals/l10_always_on/ mirrors the l10_continuity predicate/mutation harness but drives the
IDLE heartbeat: it seeds a real continuous life (held self + a cognitive turn to excite the
field), runs N beats with NO user turn, and gates four falsifiable predicates, each with a
*_holds (real soak) AND a *_bites (mutation) test per CLAUDE.md schema-as-proof:
- H1 closure — every observed idle beat versor_condition < 1e-6 (held over uptime, READ
never repaired); bites on a breached beat AND on a vacuous no-field soak.
- H2 bounded idle — a no-work beat adds NOTHING to the vault (no idle leak — invisible at
5 beats, fatal at 100k); bites on idle vault growth.
- H3 convergence — a saturated idle life SETTLES and stays settled (no re-awakening), at
rest at the end, closure intact on the tail; bites on never-settling + on re-awakening.
- H4 reboot resume — a reboot mid-soak resumes the SAME life (strict identity guard passes,
pre-reboot DERIVED learning survives, post-reboot closure holds); bites on failed
resume + on lost learning.
Measured (5000 idle beats, reboot@2500, ~20s): ALL gates pass — versor_condition flat at
1.389e-07 (no drift, no repair), vault bounded at 6 (no idle leak), converged at beat 1
with a 4999-beat at-rest tail, reboot resumed the same life with learning intact. This is
the empirical resolution of the L10 riskiest-unknown FOR THE IDLE PATH (the closure-by-
construction ruling covered the field-transition walk; this covers indefinite idle uptime).
Honestly NOT covered (recorded in the report, no silent skip): the continuously-LEARNING
life's resource cost under a sustained new-fact stream (O(n²) snapshot; per-run lived_life)
— out of scope until an afferent/intake feed + incremental persistence exist (the next
frontier).
Run on demand: PYTHONPATH=. python -m evals.l10_always_on [n_beats] [reboot_beat]. Path-
scoped out of CI smoke (like l10_continuity); runs in post-merge full-pytest. Additive — a
new eval lane, no existing files touched. 12/12 lane tests + architectural invariants green.
The L10 heartbeat loop (run_continuous) had no process to drive it; `core always-on`
is that process — the T-experience spine made runnable. It ticks idle_tick on a wall-clock
cadence so the engine LIVES and LEARNS with no user turn, persists lived_life.json (the
workbench Lived Life surface) + the checkpoint, and resumes the SAME life on restart.
- chat/always_on.py: run_continuous gains unbounded operation (heartbeats=None, runs until
stop) + an interruptible inter-beat wait (_sleep_until_stop) so shutdown latency is one
slice, not the cadence interval. Persists the run's identity pack ids (resume-verdict
faithfulness). on_heartbeat is now best-effort (a broken log pipe can't kill the life).
- chat/always_on_daemon.py (new): the daemon shell — a single-instance OS lock (fcntl.flock:
kernel-held, atomic, auto-released on death — no stale window, no PID-reuse, no half-written
race), SIGINT/SIGTERM -> graceful stop (handlers saved/restored), the continuous-life config
FORCED on, ephemeral (--no-load-state) writes no durable artifact. Foreground + explicit:
no hidden background execution (CLAUDE.md); only writes the engine-state dir it was given.
- core/cli.py: `core always-on [--interval --max-beats --no-load-state --quiet]` with per-beat
+ summary logging; validates --interval; reports IdentityContinuityError / IncompatibleEngine
StateError (the "different life / newer build" cases) as clean refusals, not tracebacks.
- workbench/readers.py: ENGINE_STATE_ROOT now honors CORE_ENGINE_STATE_DIR (= the daemon's
resolved dir), so the workbench can't be split-brained (reading REPO_ROOT/engine_state while
the daemon writes elsewhere); the Lived Life resume verdict recomputes from the persisted
pack config, not a default config (no false substrate_changed for a non-default-pack life).
- Lived Life absence state now points at the real `core always-on` command (loop closed).
Adversarial 4-lens review (lock/concurrency, signals/shutdown, invariants/trust-boundary,
test-vacuity/CLI) caught 16 findings; this fixes all real ones — the HIGH lock races (two
daemons over one life), the env split-brain, the IO-kill, the uncaught identity/schema errors,
the unvalidated interval, the ephemeral-artifact shadow, and the resume-verdict pack-id bug —
and closes the two test-coverage gaps it flagged (real SIGTERM path + config-forcing-at-the-
runtime boundary).
Tests (non-vacuous): 11 daemon (flock live-holder refusal, leftover-lock reclaim, unbounded+
stop, interruptible sleep, forced-config-at-boundary, no-load-state guard, REAL SIGTERM
subprocess) + the reader pack-id discrimination test (fails under the old default-config bug).
245 workbench+invariants+always-on Python green; frontend tsc + vitest green; `core always-on`
verified end-to-end (bounded, real SIGTERM graceful stop, interval rejection).
engine_state/always_on.lock is runtime state (gitignored, ADR-0146 pattern).
The L10 heartbeat (chat/always_on, #747) holds CORE alive over uptime but had no
surface. This adds the read-only Lived Life route that renders the continuous-life
evidence: the heartbeat over uptime + the resume-as-same-life verdict — both halves
of "one continuous life" on one surface.
Persist-first, never recompute engine-owned values:
- chat/always_on: serialize_report + write_lived_life persist a run deterministically
(sorted keys) to engine_state/lived_life.json; run_continuous gains an opt-in
report_path so a real continuous-life run leaves its evidence where the workbench
reads it. closure_ceiling is persisted so the artifact is self-describing.
- workbench/lived_life.py: projection + a fail-closed validate() gate — the wrong=0
analogue for the continuity surface: closure_held/closure_observed/totals/converged
are each re-checked against the per-beat measurements, and resume_status is re-checked
against identity-vs-current-substrate, so a tampered artifact RAISES rather than
rendering a false claim (a beat lying about a breached ceiling, an inflated closure,
a miscounted total, a falsely-claimed resume).
- workbench/readers.lived_life(): reads the artifact, computes the resume verdict from
the persisted identity vs the canonical engine_identity_for_config (fail-soft ->
"unknown", like IdentityContinuity). Honest absence when no run has been persisted.
- GET /lived-life + LivedLife/LivedLifeHeartbeat schemas (snapshot regenerated; the
schema-drift gate proves every field is mirrored in src/types/api.ts).
The resume verdict made felt: would_resume / substrate_changed / unknown IS the L11
reboot guarantee (a reboot recomputes identity and refuses if it differs) — so the
surface shows this life wakes up as ITSELF, not a copy. The per-reboot lineage chain
stays owned by Runs > Identity (honest cross-link).
Frontend: /lived-life route (Evidence section, route count 15 -> 16). Renders the
headline (heartbeats, closure-held-by-construction, learned-while-idle, at-rest, resume
pill), the summary, the heartbeat timeline (closure flat below the ceiling — read, never
repaired), and the resume verdict. Honest absence + ADR-0162 route conformance
(loading/error/empty), fail-closed like Vault/Calibration.
Tests (non-vacuous): 12 backend (every tamper case raises; resume tracks identity vs
substrate; run_continuous(report_path) round-trips a readable+valid artifact) + 4
frontend render tests (recorded life renders; a breached beat shows the warning, never a
false "held"; a changed substrate shows would-refuse, never a false resume; absent shows
honest absence). All workbench Python (167) + affected vitest (167) + tsc + vite build
green; architectural invariants green.
engine_state/lived_life.json is runtime state (gitignored, ADR-0146 pattern).
The 'one continuous life' telos had three built pieces (turn loop, Shape B+ resume,
idle_tick learning) but no process holding the engine alive+learning over uptime. This
adds that heartbeat loop: chat/always_on.run_continuous ticks idle_tick on a cadence so
the engine LIVES and LEARNS even when no one is talking to it, READS (never repairs) the
closure invariant as evidence each beat, and persists so the life survives interruption
and resumes as the SAME life.
Proven by 3 falsifiable soak tests (non-vacuous): lives (closure observed + held, real
field excited, ~7x under the 1e-6 ceiling); learns while idle (Step-D consolidation
DERIVES and STORES member(socrates,mortal) during idle — absent before the heartbeat,
present after); converges (saturated life stops churning); survives interruption as the
SAME life (strict identity guard enforces it on reboot + the consolidated STORED record
survives, not mere re-derivation); never repairs (field byte-identical after the run).
Safety by composition, no new authority: idle_tick stays proposal-only (HITL untouched)
+ sound proof-gated SPECULATIVE session-memory consolidation; closure owned by
algebra/versor.py (heartbeat only reads versor_condition — no hot-path repair).
Adversarial 3-reviewer panel: no-hot-path-repair PASS, wrong=0 PASS; the panel's
proof-quality findings are fixed — removed the tautological identity_continuous claim
(engine identity is config-derived, invariant by construction), reframed the resume test
to prove ACCUMULATED learning survived (stored record, not re-derivation) under the strict
identity guard, surfaced final_checkpoint_ok (no silent swallow), and softened the
docstring (this is the heartbeat LOOP a daemon runs; the daemon shell is a follow-up).
Scope: the reusable loop ships; a production daemon (CLI entry, real cadence, signals)
is a thin follow-up. Purely additive (no existing file touched).
First phase of the domain-general compositional reading layer (the comprehension
coverage wall is composition — docs/analysis/comprehension-coverage-wall-map-2026-06-14.md).
M1 is a pure PARITY refactor on the flagship logic path, no new capability:
- new generate/composition/ package: LogicChainPlan (plan.py) + lower_logic_chain
(lower_logic.py), the is-a chain lowering extracted BYTE-IDENTICALLY from
determine.py::_verify_subsumption.
- _verify_subsumption now builds a plan -> lowers it -> routes through the UNCHANGED
evaluate_entailment gate. The composer proposes structure; the sound ROBDD gate
remains the sole wrong=0 firewall.
- only the logic instantiation ships; no math lowering, no join-op vocabulary
(defer-substrate-vocab-commitment — the chain discriminates on its relational
predicate, an explicit join-op field lands when a second op dispatches on it).
Verification: byte-identical lowering (3-reviewer adversarial panel: byte-parity PASS
char-for-char, wrong=0 PASS — the instance-of-fallacy refusal mutation-proven
load-bearing); 5 new non-vacuous lowering tests; 28 determine/transitive/consolidation
+ 163-test broad sweep (incl. gsm8k serving + ADR-0218) green; cognition eval 100%.
A1 (substrate fix, not UI): en_collapse_anchors_v1 declared only love/peace/justice,
but the logos packs reference covenant_love/shalom/tzedek + heart/soul/breath/holy/time.
Declare all 8 with their real ADR-0073 provenance (source-concept names where they
exist) and recompute the lexicon checksum. Now every cross_lang.no_english_collapse
edge resolves to a real declared entry — grc_logos_cognition_v1 and he_core_cognition_v1
go from 7 invalid targets to 0 (verdict warning -> unknown; never CLEAR while holonomy
proof is absent). The geometry resolves; the check is NOT suppressed (the LG-1
relation/prefix carve-out stays removed). Test updated to assert real resolution;
invalid-detection branch still covered by the ghost-target fixture.
A2: Identity tab shows the real pack manifest (now fetched via /contents) instead of
an overview projection — the actual passport, data already present.
NOTE (curation follow-up): love (Greek agape collapse) and covenant_love (Hebrew chesed
collapse) may be intentionally distinct per-language anchors or duplicates of one
concept — left both declared rather than gamble on consolidating curated theology.
Backend 25 + frontend 520 tests pass; tsc + build clean.
Measuring the holonomy tri-language resonance (intended for a Studio proof-card)
showed it is NOT a robust proof: the engine's own holonomy_similarity (CGA inner
product) anti-correlates, and the Euclidean 'aligned closer than misaligned'
claim passes only via averaging in the close Hebrew distance + one cherry-picked
negative (1.3% margin) — the aligned Greek clause is itself farther than the
negative, and the verdict flips ±20-55% under other negatives. Decoration, not
proof (CLAUDE.md, Schema-Defined Proof Obligations).
- docs/analysis/holonomy-resonance-proof-not-robust-2026-06-14.md: the rigorous
finding (numbers), why a Holonomy proof tab cannot be built honestly yet
(stays missing_evidence), and bounded research questions.
- Downgrade the two clause-resonance decoration tests to honest tripwires that
assert the true state and fail (pointing to the doc) if the resonance becomes
real. Token-pair cga_inner tests left intact + flagged as a separate, un-audited
claim.
70 holonomy-adjacent tests pass.
Clears the long-standing B4 block: the leeway decision was already made on the
serving path (chat/runtime.py::_surface_estimate has a real LicenseDecision +
the ReachPolicy) and then DISCARDED — never threaded to the result, and the
workbench can't import reliability_gate. This wires it through.
Producer (observational, never authorizing):
- core/cognition/leeway.py: LeewayRecord + build_leeway_record(reach_level,
license_decision) — duck-typed on the decision, zero new cross-package
coupling. Maps to: no decision -> "unknown" (STRICT, no latitude); denied
-> "blocked" (gate consulted, said no); licensed SERVE/PROPOSE widening ->
the real class / theta / "[approximate]" disclosure. "verified" is never
emitted (RESERVED state). source_digest content-addresses the decision
(deterministic, no wall-clock).
- core/cognition/result.py: additive `leeway: LeewayRecord | None = None` on
CognitiveTurnResult.
- core/cognition/pipeline.py: build it at result construction from the data
the runtime ALREADY exposes (response.reach_level +
runtime.last_turn_accrual().license). chat/runtime.py is UNTOUCHED.
- workbench/api.py: _leeway_evidence_from_result maps result.leeway ->
LeewayEvidence (pure projection; no reliability_gate import — firewall
intact). The journal already persists it; the B4a UI (Replay / Proposals /
RightInspector) already renders it — no frontend or schema change needed.
Safety (this touches the serving path, so proven, not asserted):
- trace_hash is a NAMED-field hash (core/cognition/trace.py); `leeway` is not
in it -> byte-identical serving. All provenance/trace tests pass.
- response_governance STRICT stays byte-identical (375 governance/serving/
provenance tests green, incl. the live-wiring + estimation-lane + ADR-0206
seam tests).
- core eval cognition: 13 cases, 100% intent / groundedness / versor closure.
- replay determinism holds (leeway is in CRITICAL_FIELDS; deterministic).
Tests: engine (build_leeway_record: strict/blocked/SERVE/PROPOSE, no "verified",
deterministic digest) + workbench mapping (field-for-field, honest absence,
invalid-enum clamp) + integration (a real turn now carries an honest leeway
record, not the null "No evidence recorded"). 151 workbench/leeway Python + 68
frontend (leeway/replay/proposals/schemaDrift) green; schema-snapshot unchanged.
Docs: gate cleared (b4-leeway-feasibility-gate.md), residue ledger flipped to
implemented, scope brief is b4-leeway-producer-scope-2026-06-13.md.
The "they'd want to use it" first-run surface: a curated narrative that makes
the engine's discipline legible to a newcomer — bring a claim from any model and
watch it get decided, refused, or replayed. Proposer authority ignored.
Honest by construction (the risk with a narrative surface is theater):
- workbench/tour.py determinism_tour() is a curated ordered narrative BOUND to
the real demo registry. Intro (provider-agnostic thesis) → three demo steps
(deductive entailment decides only on engine+oracle agreement; epistemic
truth-state refuses a wrong proposer; proof-carrying promotion ignores
proposer authority) → payoff (replay-to-same-hash + the citable evidence
bundle).
- Each demo step's what_this_proves / what_this_does_not_prove cards and the
demo title are PULLED FROM THE REAL DEMO SPEC — never re-authored — so the
tour can never claim more than the demo it points at.
- A step referencing a missing demo FAILS CLOSED (KeyError), not a dead link.
Tests assert both (cards == spec; phantom demo raises).
Backend: schemas.py DeterminismTour/TourStep; GET /tour. schema-snapshot regen.
Frontend: /tour route registered in the registry (Determinism section, 14
routes; nav/palette/guide counts updated); TourRoute — thesis hero + ordered
step cards with the honesty cards + links to the real demos / replay.
Validation: 140 workbench Python tests incl. tour drift guards; 472/472 frontend
incl. routes/routeConformance/routes.docs (guide↔registry), Shell+palette counts
(14), schemaDrift, and the tour UI test; pnpm build clean; git diff --check
clean. No serving-path imports.
The "they'd want to use it" deliverable: a turn's evidence exported as ONE
deterministic, content-addressed, citable artifact — composing the Phase-C
evidence (pipeline + field) with the trace and the calibration leeway verdict.
Backend (read-only, no engine execution):
- schemas.py: EvidenceBundle.
- workbench/evidence_bundle.py: build_evidence_bundle(entry) assembles a turn
journal entry into the bundle and computes bundle_digest. The digest
content-addresses the DETERMINISTIC cognitive evidence only — journal
position + wall-clock (turn_id, journal_digest, replay_reproducer,
generated_from) are carried for provenance but EXCLUDED, so the same turn
content reproduces the same digest regardless of journal position.
- api.py: GET /trace/{turn_id}/bundle. schema-snapshot.json regenerated.
The bundle carries a replay *reproducer* command (how to verify) rather than a
live-run replay, so the artifact itself stays deterministic — verification is
the consumer's step: re-run the prompt sealed, confirm trace_hash, recompute the
bundle, check the digest.
Frontend:
- types/api.ts EvidenceBundle; client/query hook; Trace route **Bundle** tab —
citable digest, "what this proves / does not prove" honesty note, the
reproducer, and a deterministic JSON download (Blob anchor, leak-safe).
Validation: 135 workbench Python tests incl. non-vacuous bundle guards (digest
reproducible, journal-position/wall-clock excluded, any evidence change flips
the digest, missing Phase-C evidence honest); 468/468 frontend incl. schemaDrift
+ the citable-download bundle test; pnpm build clean; git diff --check clean. No
serving-path imports.
C2-a surfaced contemplation runs but rendered each scene as a flat JSON dump —
outputs, not process. C2-b makes the loop legible: every scene is now a typed
stage in the canonical ADR-0172 arc.
Reader-first (no theater):
- schemas.py: ContemplationScene gains a typed loop projection — stage_role
(cold_attempt | engine_enrichment | engine_proposal | operator_ratifies |
grounded | other) plus the connective ids (proposal_id, candidate_id,
proposal_state, grounding_source). New ContemplationStageRole Literal.
- readers.py: _contemplation_scenes derives stage_role from the scene id
(closed set, "other" fallback) and pulls the connective ids out of the raw
detail. schema-snapshot.json regenerated.
UI:
- ContemplationRoute: the run detail now renders the arc as a staged process —
"attempt → enrich → propose → ratify → grounded" with named stage roles,
cold→grounded bookends (surfaces pulled out of before/after), the connective
ids as evidence, and the raw detail tucked into a collapsible (not lost).
Honest wrinkle (surfaced, not faked): the fixture proposals do NOT resolve in
the live proposal log (source_kinds exemplar_corpus/operator, none
contemplation), so the proposal id is shown as evidence but is intentionally
NOT a clickable cross-route link — a dead link would be theater. Live
Proposals/Calibration navigation is deferred to reader-verified linking once
real contemplation proposals reach the log.
Validation: 128 workbench Python tests + new reader-projection tests (canonical
arc → roles, unknown → "other", id extraction, detail preserved); 466/466
frontend incl. schemaDrift + the staged-process / no-dead-link test; pnpm build
clean; git diff --check clean. No serving-path imports.
Makes the CL(4,1) field geometry legible, honestly. The engine owns the field;
this surfaces ONLY the exact scalar invariants it computes — never the raw
multivector — so the workbench shows "this is the geometry, it's exact, it
can't fake coherence" without a decorative blob or any motion.
Persist-first (the C3 gating work was Python, not React): the honest scalars
were computed live per turn but discarded. Now captured per turn into the
journal so a read-only surface has real evidence.
Backend:
- workbench/field_evidence.py: FieldEvidence computed from the engine result —
exact versor_condition, field_valid (vs the 1e-6 ceiling), a content-
addressed field_digest (sha256 of the engine-canonical array bytes), and
cga_inner(before, after) as the exact transition value. Raw field bytes
never cross the boundary: only floats + digests. validate() is fail-closed —
field_valid can never disagree with versor_condition vs the ceiling (the
wrong=0 analogue for the geometry). No engine math re-implemented
(versor_condition / cga_inner imported from algebra; bytes via array_codec).
- workbench/schemas.py: FieldEvidence dataclass; field_evidence on
ChatTurnResult + TurnJournalEntrySchema. schema-snapshot.json regenerated.
- workbench/journal.py + api.py: persisted at from_chat_turn; first-class read
endpoint GET /trace/{turn_id}/field (trace facet, consistent with /pipeline).
- workbench/replay.py: field_evidence classified CRITICAL — replay now also
proves field determinism (digest + scalars must match on re-execution).
Frontend:
- types/api.ts FieldEvidence + field_evidence passthrough; client/query hook;
FieldInvariantCard (measured value vs ceiling, cga_inner transition, digests;
honest missing_evidence; no blob, no motion); Trace route Field tab.
Honest-empty for pre-widening journal rows (missing_evidence). Deferred:
cross-turn field-coherence trends, session-level field persistence.
Validation: 138 workbench/practice Python tests (incl. non-vacuous field guards
+ replay field-determinism); 465/465 frontend incl. schemaDrift; pnpm build
clean; git diff --check clean. No generate.derivation / reliability_gate /
stream / field.propagate / vault.store imports.
Lands the Phase C "make cognition legible" slice plus Phase A residue, all
backend-reader-first over real engine data (no theater, read-only doctrine
intact, zero serving-path imports).
C1-a — Cognitive pipeline record (persistence-first, per #729 worthiness edit):
- workbench/pipeline_record.py: curated CognitivePipelineRecord over the real
CognitiveTurnResult (input → intent → proposition_graph → articulation_target
→ realizer → walk_telemetry → trace_hash). Raw field multivectors are
DELIBERATELY excluded; _assert_no_raw_field_payload recursively rejects raw
field keys, and validate_pipeline_record fails closed on missing/duplicate
stages, non-recorded status, or dangling edges — the UI can never receive a
partial record that claims to be complete.
- test_workbench_pipeline_record.py: non-vacuous guards — missing stage,
monkeypatched new required stage, and injected raw {"F": [...]} each raise.
C2-a — Contemplation as a process: /contemplation route over real persisted
contemplation/runs/*.json (glob reader; honest-empty when absent).
C4-a — Identity continuity (L10/L11): RunDetail.identity_continuity + Runs
Identity tab, sourced from the real core.engine_identity (engine_identity /
parent_engine_identity lineage relation, re-derived to verify).
Demo Theater: renders backend-owned proof-promotion + entailment DAGs.
Phase A residue: density preference wired end-to-end (settings → shell → tokens);
cross-route consistency touch-ups.
Infra: local API CORS now echoes only validated 127.0.0.1/localhost origins
(hostname-checked, not arbitrary reflection) so Vite fallback ports work.
Route chunk-split keeps the build warning-free.
Cleanup: corrected the stale ADR-0175 practice-lane assertions (build_report is
6 correct / 0 wrong / 44 refused after the current serving lane; wrong=0 held)
and the two registry-derived count tests (LeftNav + CommandPalette 12 → 13 for
the new Contemplation route).
Docs: runtime_contracts.md (pipeline-record contract), UI-UX-GUIDE,
api-contract-v1, data-shapes-v1, wave-M-worthiness, phase-a-residue-ledger.
Validation: 106 workbench/practice Python tests green (incl. wrong=0 lane +

Completes the Wave M B3.5 consolidation slice (b–e), built on #728.
B3.5-b — calibration as a first-class evidence subject (`calibration_class`,
address `calibration:<class_name>`): RightInspector projection + Evidence
Chain Rail semantics (serving-discipline evidence, not runtime truth).
B3.5-c / B4a — nullable `LeewayEvidence` read model threaded through turn,
replay, cognition-proposal, and math-proposal surfaces, with a shared
absence-honest card. B4 is gated correctly: the tuple exists in typed data but
no producer populates it, so the card renders absence (verified: no non-null
producer in workbench/core/chat).
B3.5-d/e — UI-UX-GUIDE.md, b4-leeway-feasibility-gate.md, phase-a-residue-ledger.md.
Practice artifact — earn-it-for-real (runner-reproducible). The committed
`report.json` (additive earns PROPOSE @0.861, 95/5/50) is now emitted by a
deterministic runner rather than copied from the queue. `propose_runner`
gains `regenerate_practice_artifacts()`, which runs ONE sealed `resolve_pooled`
practice pass and writes BOTH report.json (the per-class ledger the calibration
reader consumes) and ratification_queue.json — two projections of one ledger,
coherent by construction and byte-reproducible. `runner.main()` delegates to
it (lazy import, no cycle), so both entry points produce the identical pair.
This closes the gap where a hand-copied report.json agreed with the queue but
no runner produced it. `resolve_pooled` is the aggressive sealed PROPOSE-regime
scorer (proposal-only/HITL, unsafe for serving, legitimate for
attempt-and-eliminate); wrong=5 is the sealed-practice learning signal, NOT the
serving wrong=0. No serving/derivation/reliability_gate source touched; the
practice lane is not in the serving-frozen SHA gate.

First Wave M / Phase B piece (GATING): read-only backend that makes the
calibrated-learning / serving-discipline loop inspectable — 'the engine
earns the right to guess', ADR-0175.
The workbench computes NONE of these numbers:
- GET /calibration/classes — per-class gold-tether view from the persisted
practice arena ledger (evals/gsm8k_math/practice/v1/report.json per_class).
Each class's reliability_floor is the engine's own one-sided Wilson
conservative_floor (via ClassTally.reliability); PROPOSE (θ=0.85) / SERVE
(θ=0.99) license verdicts come from core.reliability_gate.license_for.
Failures-first ordering. A test proves the reader's floor equals a direct
conservative_floor() call — no re-implementation.
- GET /serving/metrics — the live correct/refused/wrong counts read unchanged
from the committed train_sample + holdout_dev report.json (currently
4/46/0 and 5/495/0 — wrong=0). Never re-runs a lane.
Honest current state: the committed practice ledger's three classes
(additive/divisive/multiplicative) are all below N_MIN=10, so none has
earned a license yet — the reader shows exactly that, no fake green light.
- workbench/calibration.py: pure readers; imports core.reliability_gate;
EvidenceUnavailableError -> 501 (fail-closed) when the artifact is absent.
- schemas + TS mirrors (CalibrationClass, ServingMetrics); both snapshots
regenerated (deterministic); both drift gates pass.
- trust boundary: read-only over committed artifacts + engine-owned
derivation; no execution, no mutation, no license ever changed.
Verified: 30 Python tests (incl. the no-reimplementation proof + fail-closed),
390 vitest, both schema drift gates, snapshots deterministic.
Replaces the W-026 501 stub. Re-executes a journaled prompt in a sealed
fresh runtime (ChatRuntime(no_load_state=True): no checkpoint load, no
checkpoint write, no proposal lineage) and compares the envelope
leaf-by-leaf against the recorded TurnJournalEntry.
Design correction vs the scoping doc (amended in-doc): journaled turns
each ran in a fresh ChatRuntime(), never one continuous session, so
genesis-PREFIX replay would manufacture spurious divergence; shipped
basis is sealed_fresh_runtime_single_turn (O(1)). origin_state:
"unrecorded" — the journal does not record whether the original turn's
runtime loaded a checkpoint, so divergence is reported as nondeterminism
OR origin-state influence, never disambiguated.
- workbench/replay.py: pure comparison + injected executor; every
TurnJournalEntry field classified critical/informational exactly once
(exhaustiveness enforced by test)
- api.py: route wiring under _CHAT_TURN_LOCK; runtime failure -> 500
runtime_unavailable, no comparison may be fabricated
- schemas: additive TurnReplayComparison/TurnReplayDivergence (W-026
artifact-keyed pair retires with the frontend Replay Moment PR)
- tests: 10 obligations incl. tamper-prompt, tamper-leaf precision,
no-execution-no-comparison, no-trace (journal + engine_state bytes),
wall-clock tolerance, sealed-construction proof
- snapshot regenerated; NOT_YET_MIRRORED debt entries for the two new
classes (mirrors land with the frontend PR)
- api-contract-v1.md § Replay rewritten for the turn-keyed shape
Append-only JSONL journal records the exact ChatTurnResult envelope returned by /chat/turn with stable turn_id, trace_hash, all three surfaces, verdicts, and deterministic journal_digest.
GET /trace/turns and GET /trace/{turn_id} serve journal evidence for the Trace route frontend. Read model only; no teaching, pack, or journal-owned engine_state mutation.
Local deterministic demo exposing the formal entailment substrate as its
own public authority: the proposer's verdict/confidence/proof are data
only; CORE recomputes propositional entailment through the pinned ROBDD
engine (generate.proof_chain.entail.evaluate_entailment_with_trace),
independently cross-checks with the deductive lane's code-disjoint
truth-table oracle (evals.deductive_logic.oracle.oracle_entailment), and
serves entailed/refuted/unknown only when both procedures agree —
refusing on inconsistent premises (no vacuous entailment), out-of-regime
input (by design, before grammar), a distinct-atom regime bound (honors
the brute-force oracle's small-atom contract), and engine/oracle
disagreement (test-only fault injection, defensive refusal).
Seven committed scenarios with byte-pinned expected artifacts; 38 tests
covering recursive schema closure, output-smuggling-before-evaluation,
proposer-garbage byte-invariance in both directions, oracle module
disjointness, trace-hash folding of trace + oracle verdict, runner
hardening, and INV-21/24/29 discipline of the demo files.
Two-pass hardening of the #690 demo so no epistemic state is proposer-mintable:
Pass 1 (sealed corpus, from the reconciliation pass):
- evidence items are references only (evidence_id + content_sha256) resolved
against a committed content-addressed corpus (evidence_corpus.json)
- support derived from committed subject/predicate match; independence from
distinct provenance_root values; proposer support/independence labels are
rejected by the closed schema
- evidence-strength taxonomy (substrate-capability vs interface-contract) in
PUBLIC-DEMO-ROADMAP / DEMO-PACKAGING-CHECKLIST; position-paper refinements
Pass 2 (entailment-decided inference, closes a live false-status hazard):
- the merged inferred leg required only that premise IDs resolve — a claim
with no support citing one unrelated record as a premise was assigned
'inferred' (empirically confirmed). inferred is now decided by
generate.proof_chain.entail (sound+complete ROBDD) over resolved corpus
premises, cross-checked against the independent truth-table oracle
(evals.deductive_logic.oracle, no shared code); proof keys + oracle verdict
in the trace; disagreement => defensive refusal; refutation => contradicted
- committed adversarial scenario unrelated-premise-still-undetermined proves
the attack now lands on undetermined
- corpus seal (corpus_sha256) pinned into every evaluated trace; scope
refusals no longer consult the corpus; corpus cache hands out copies;
claim subject/predicate constrained to atom-compatible snake_case
- .gitignore: private packet dir, agent worktrees, tooling artifacts
Validation: 30 demo tests; 96 across all three demo suites; 7/7 scenarios
double-run byte-identical; 61 architectural invariants green.
Local deterministic public evidence for the ratified PCCP capability:
proposer submits claim + proof candidate + status/confidence garbage; CORE
ignores proposer authority, fresh-reads curator-certified store state,
recomputes the proof under the pinned engine, and promotes/refuses only
through VaultStore.apply_certified_promotion. The trace proves the decision.
- demos/proof_carrying_promotion/{schema.json,authority.py,run_demo.py}:
closed recursive schema (output fields unsuppliable at the root), the REAL
decider (teaching.proof_promotion.certify_promotion) and the REAL owner —
no demo-local promotion reimplementation. The local arena is rebuilt via
VaultStore.from_dict over dict-literal metadata: demos/ is scanned by
INV-21/INV-24/INV-29, and the demo adds no vault writer, no recall site,
and no status-transition site (proven in tests with the invariants' own
detectors).
- 8 fixtures + pinned expected artifacts: entailed-promotes,
proposer-status-ignored, non-coherent-premise, uncertified-reading,
tampered-certificate (fails byte replay), stale-premise-status (same
honest certificate digest as the promoting run — live state is what
differs), non-sequitur, invalid-state-smuggling (rejected before
evaluation, authority_evaluated=false, null digest).
- Hardened runner per the #688/#690 pattern: default out/ dir, unsafe
output roots refused, --write-expected explicit, double-run byte-identity
enforced per fixture, scenario pass/fail summary.
- tests/test_proof_carrying_promotion_demo.py (26): expected-artifact
conformance, tamper detection, proposer-garbage decision-invariance (incl.
on the promotable setup), refused-cases-mutate-nothing, REFUTED-never-
demotes, trace-hash folds certificate digest, forbidden-import/call scan
(incl. uuid/random/time), INV-21/INV-29 allowlists pinned unchanged, no
named-company/strategy terms.
No runtime turn integration; promotion remains SPECULATIVE->COHERENT only;
README carries the full honesty ledger.
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.
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.
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).
This demo assigns epistemic truth-state only and runs no normative/
safety/ethics clearance pass, so it has no basis to positively clear
a claim. Drop the verified->cleared mapping: verified now reports
normative_clearance=unassessable like every other non-invalid output.
Updates authority.py, regenerates the affected expected trace hashes,
tightens the test (verified asserts unassessable) and adds an invariant
test that no non-invalid output is ever cleared, and corrects the README
honesty ledger.
A model-style proposer submits a claim, evidence bundle, and optional
bounded-inference block; CORE alone assigns the typed epistemic state
drawn from the canonical core.epistemic_state taxonomy (no parallel
enum) and emits a deterministic, replayable evidence artifact.
The proposer cannot set assigned_state, status, trace_hash,
authority_path, evidence_ledger, or normative_clearance: the closed
recursive schema rejects any root-level injection before state
evaluation runs, and proposer-supplied proposed_state/trace_hash are
recorded as ignored and never read.
Adds closed schema, six fixtures, pinned expected artifacts, a
double-run byte-identical runner with hardened output-dir policy, and a
22-test suite. No network, subprocess, eval/exec, model API, or side
effects beyond demo output.
A narrow, auditable proof path for the hybrid-mode boundary: a
Claude/Fable-style System 1 proposer submits an MCP-shaped tool call
(core.semantic_derivation.verify); CORE re-derives via the ADR-0184
derivation lane, keeps sole acceptance authority, refuses or asks when
it cannot honestly answer, and emits a deterministic replay/provenance
trace for every decision.
Boundary properties (each pinned by a failing-if-removed test):
- the proposer has no commit path: additionalProperties:false schema,
and the demo modules import nothing from generate.* (AST-scanned with
a planted-bypass self-test) — the lane is consumed only through the
ADR-0184 S4b audited trace facade;
- 'verified' requires pool commit AND clean commit-law/faithfulness
audits AND a gold-audited envelope.json entry AND byte-match to the
pinned derivation trace (measured: 118 of the off-serving pool's 231
corpus commits disagree with lane gold, so a bare pool commit is
never served — scenario s4 shows the refusal on a commit that even
matches gold);
- the ask leg is the real Q1 stack (router -> limitation -> Q1-D
producer -> carried handle -> gated serving), dark by default,
tamper-fail-closed on the content hash;
- authority_path names only consulted authorities; responses are
deterministic (double-run byte-identical) and pinned under expected/.
No serving/runtime change; no CLAIMS/metrics/telemetry/lane-pin
movement; no network or Anthropic API dependency (System 1 payloads are
clearly-labeled static fixtures).
