Two things, both surfaced by finally being able to run the tree.
## A pre-existing silent red
tests/test_lane_sha_verifier.py::TestExpectedLaneCoverage was RED on clean
main — confirmed by running it in a pristine worktree at origin/main, and the
file is untouched by any of this branch's work. deduction_serve_v1 (ADR-0256)
and curriculum_serve_v1 (ADR-0262) shipped during the generalization arc and
neither was added to EXPECTED_LANES.
The roster's `extra` assertion is a deliberate tripwire: a new lane is supposed
to fail it once so an author acknowledges the addition. Nobody did, and nothing
caught it, because that file is in neither `smoke` nor `deductive` — no local
gate and no CI job runs it. Same silent-red family as the exact-tuple pin S5
found in passing, and as the register-axis e2e tests that sat red for two days.
This commit is the acknowledgement the tripwire was asking for.
That it took running the full tree to find is the argument for the rest of this
commit.
## scripts/ci/local-ci.sh
AGENTS.md says the merge bar IS the local run. There was no single entry point
for it, and on any host without Python 3.12.13 exactly there was no local run
at all: pyproject pins requires-python == "3.12.13", so uv sync --locked fails
outright and every gate becomes unrunnable.
sh scripts/ci/local-ci.sh --tier smoke|gate|full
`gate` is the three pre-push steps; `full` is the whole tree in parallel. Suite
membership is read from core/cli_test.py::TEST_SUITES through the CLI and never
restated, so this runner cannot drift from the hook the way smoke.yml drifted
from the local list.
Interpreter contract, deliberately fail-closed: the pinned interpreter is
CANONICAL, and the runner refuses on anything else with instructions.
--allow-interpreter-fallback opts into any 3.12.x and stamps every run
NON-CANONICAL. Same discipline as ratified_ledger's missing_ok and the MLX
skip path: a degraded mode is legitimate, a degraded mode reporting itself as
the real thing is not.
Evidence recorded in the script header so the flag is not cargo-culted: the
committed-SHA / trace_hash / content_sha256 / lane-SHA pin set (119 tests) was
run on 3.12.11 and 118 passed, the one failure being the stale roster above,
which fails on 3.12.13 too. That is evidence the exact pin is not load-bearing
for bit-exactness — it is NOT a ruling that it should be relaxed. Relaxing it
is a reproducibility decision and belongs to a human.
## Observed, not fixed
Something in the suite writes a real proposal artifact into
teaching/proposals/derived_close_facts/ instead of a tmp_path. The three test
files that name that sink all override it correctly, so the leak is elsewhere —
likely an idle_tick/contemplation path exercising DEFAULT_SINK. Untracked
residue, removed here, flagged for follow-up. Notable because it is only
visible now that the parents[3] bug is fixed and the sink resolves inside the
repo.
[Verification]: gate tier via the new runner — smoke 236, warmed_session 10,
deductive 285, all passed, correctly stamped NON-CANONICAL. Fail-closed path
verified (exit 3 with instructions). lane_sha_verifier 6 passed. Full tests/
tree in progress at 63% with 0 failures at time of commit.
NON-CANONICAL: Python 3.12.11, not the pinned 3.12.13. Not merge evidence.

Squashes the arc's work into one commit; the workflow-file edit it originally
carried is excluded (see the end of this message).
## Lane 1 — Workbench recorded a proved answer as ungrounded
With deduction_serving_enabled ratified ON (ADR-0256), workbench/api.py's live
chat route builds a bare ChatRuntime(), so the deduction composer decides
Workbench turns and stamps grounding_source="deduction" — but
_coerce_grounding_source carried a hand-copied whitelist of the six pre-arc
labels and silently rewrote anything else to "none". The runtime comment
reasoned this was inert because "REPL turns do not flow through Workbench's
CognitivePipelineRecord path". True, and irrelevant: the traffic flows the
other way. Stale since 2026-07-24.
Scope is one field. workbench/api.py:818 prefers TurnEvent.epistemic_state,
which read epistemic_state_needed — honest. So the UNregistered path degraded
honestly while the hand-copied whitelist asserted a falsehood; a second copy of
a closed enum was worse than no copy. Hence registration AND derivation:
GROUNDING_SOURCES exposes the Literal's members, and the coercion reads it.
workbench-ui badges/tokens/snapshot follow; enumCoverage.test.ts forces atomicity.
## Lane 2 — the ratification ceremony
The discovery loop was instrumented but not closed. teaching/ratification.py
turns a reviewed decision into a chain record, a corpus commit, and a receipt.
Its design turns on one observation: _ratified_rows DROPS unadmissible rows
silently — correct when serving, a trap when ratifying, because the file grows,
the commit lands, and the band count does not move. So the ceremony refuses to
call an append a ratification until it has re-read the curriculum through the
real loader and seen the chain arrive; a non-admitted append is rolled back.
Validation is a pre-flight courtesy, admission is the proof.
Arena queue entry and ledger reseal are deliberately NOT performed (bridge rule
1); the receipt names them. Front door: `core proposal-queue ratify`, a sibling
of `review` rather than a flag on it.
## Lane 3 — structural closures
- ADR-0263 gains rule 5: absence policy is DECLARED in CAPABILITY_LEDGERS, not
passed at the call site. An AST-matched test fails if a serving path passes
missing_ok again.
- Deductive suite added WHOLE to the pre-push gate: 285 tests in 29s against
smoke's 216 in 62s, so no coverage trade was needed.
- Smoke/CI parity assertion made bidirectional. It was one-directional, and had
drifted.
- test_prior_surface_deduction_binding.py pins correction binding on the
deduction path. The review's diagnosis did NOT reproduce — hash_surface moves
in lockstep — so it pins what is there. Mutation-checked.
- Domain-keyed ADR index over 312 flat-numbered files, explicitly partial.
- Arc-close brief template, plus this arc's own brief filled in against it.
## Lanes 4 and 5 — two premises falsified by measurement, one of them mine
Math 4.2: baseline reproduced (correct=5 wrong=0 refused=495); all four named
cases traced to one seam with each gap isolated by one-variable probes. Then the
number that changes the recommendation: the gap blocking case 0000 affects 1
case in 500, the 'than' gap blocking 0001 affects 2. ADR-0251's prohibition on
per-case growth now rests on a count. No reader change made.
CGA: versor_condition is 0.22% of a turn, not the "~10x proof latency" I claimed
— that multiplied an isolated microbenchmark by a call count and compared it to
a single verdict's latency. The real cost is geometric_product at 33,986
calls/turn (~73%) via cga_inner in search paths. The obvious closed form is NOT
bit-exact (954/4000 in f32); backend.vault_recall's serial fold IS (3000/3000,
worst-rel 0) and is the correct target. cargo test could not run —
static.crates.io is denied by the sandbox network policy — so the Rust parity
question stays open and the typestate lane is carried forward, not shipped
uncompiled.
## Not landed: three lines owed to .github/workflows/smoke.yml
The CI smoke gate is narrower than the local one —
test_pack_draft_serve_boundary.py (ADR-0253 INV-33) has been local-only, unseen
because the parity pin checked one direction. The edit was authored and rejected
at push for lacking the `workflow` OAuth scope, so it is recorded as a named,
dated PENDING_IN_CI exception rather than dropped: the assertion still fires on
any new divergence, and a second guard fires once the three land.
[Verification]: pre-push gates all green — smoke 236 passed, warmed_session 10
passed, deductive 285 passed. Ratification 14, ADR index 5, CLI suites 10.
Grounding/epistemic sweep 741 passed 1 skipped. workbench-ui 598 passed across
73 files, tsc -b clean. capability index 11 passed, digest unchanged. Math
holdout correct=5 wrong=0 refused=495. Committed chain corpora byte-unchanged
after the tests that write to them.
Environment caveat: the repo pins requires-python ==3.12.13, which uv cannot
fetch for linux-x86_64, so `uv sync --locked` fails. All Python runs used a
scratch venv on 3.12.11 with declared deps — not the locked universe, not the
full ~12k suite. The pin was left untouched. Re-run on a 3.12.13 host before
treating this as merge evidence.

Archaeology (six worktree measurements) shows public_demo's stale pin
(7d8ba0db..., last set 2026-07-14) predates two commits that changed its
content deterministically: e7d116c9 (trace-hash format widening, benign)
and e0d1b475 (the register-axis regression's introduction, benign for
this lane at that point). But starting at 5a343b49 (T13's back-stamp,
2026-07-22) public_demo's own all_claims_supported case genuinely FAILS
and stays failing through 5224b5e0 (2026-07-24), fixed only as a side
effect of PR #110's unrelated register-axis restoration (f95ac26e) —
public_demo embeds the same register-tour scene demo_composition does.
The standing "public_demo red = the env-timeout flake, ignore it" memory
was true only for the runtime_under_budget case; it caused this real
all_claims_supported regression to hide for two days behind the same
label. Corrected the memory to triage by which case failed, not by lane
name. Re-pinned to da7fad65... (current main, 4/4 passing, verified
stable across three independent measurements) and regenerated CLAIMS.md.
Phase 2 of the generalization arc, implementing the plan's §4
curriculum-entailment gold contract. "Does force cause acceleration?" is
answered from the ratified physics chain corpus and nothing else; "Does
gravity cause acceleration?" is declined because gravity is in no pack
CORE has been taught; "Does force cause motion?" is unsettled even though
the curriculum contains both links, because nothing ratified says
causation composes.
Path (flag-gated, default off): closed question grammar -> subject routing
by ratified vocabulary -> family-scoped premise compilation from reviewed,
pack-resident chains -> the SAME argument bands (ADR-0260/0261) -> the
ROBDD engine. Zero subject-specific decision code: physics differs from
philosophy only in which rows load.
Epistemology enforced mechanically, not by convention:
- gold is a function of (curriculum, question); cases pin chain ids and
the runner FAILS a case whose pinned chain is absent or unratified;
- untaught => UNKNOWN, never "no" (open-world; silence is not denial);
- an independent oracle (own loader, ratification predicate, family table,
agreement rules, verdict rule) re-derives every gold — it disagreed once,
on "entropy reveals energy" vs "entropy causes energy", and the ORACLE
was the side that was wrong;
- anti-recall probes are a lane GUARD: a split without >=3 true-but-untaught
probes refuses to run.
Findings recorded rather than worked around (ADR-0262 §5):
- every curriculum band is UNEARNED and every answer is hedged. A band needs
n>=657 with a real outcome mix; physics teaches 7 causal + 9 modal
relations, so at most 16 questions in the subject can ever be ENTAILED.
A balanced band needs ~219 taught relations per subject×family — a ~25x
gap that only ratified curriculum content closes. Phase 2's blocker is
curriculum volume, not machinery.
- REFUTED is unreachable from present corpora (every chain is positive).
- there is NO biology domain-chain corpus; the biology OOD lane measures
fluency, not truth. The four subjects with ratified chains and mounted
packs are physics, mathematics_logic, systems_software,
philosophy_theology — the composer serves all four.
[Verification]: curriculum lane 32/32 wrong=0 with 5 anti-recall probes and
all three contract guards passing; tests/test_curriculum_serve.py 20 passed;
core test --suite deductive 252 passed; lane pinned as curriculum_serve_v1.
Completes the all/no/some square. `some` is read for the first time:
"All mammals are vertebrates. Some whales are mammals. Therefore some
whales are vertebrates." is decided entailed; "All unicorns are horned.
Therefore some unicorns are horned." is decided unsettled, with the
no-existential-import reading disclosed in the surface.
Mechanism (generate/proof_chain/exist.py): v5-VP's per-individual
lowering over a domain widened by one Skolem witness per existential
premise and — the load-bearing part — one ARBITRARY element per
existential conclusion, at which every universal still instantiates and
about which no premise asserts anything. Refuting an existential means
deriving a universal, and the arbitrary element is what makes that
derivation genuine instead of an assumption of domain closure: without
it "Rex is a wolf. Rex is not tame. Therefore some wolves are tame."
reads as REFUTED from a domain of one wolf. With it, UNKNOWN.
Four `en_exist_*` bands earned SERVE at 720x wrong=0 on the first arena
seal (25-band ledger); the 32-case hand-authored v2_exist split passed
32/32 first run; full lane 166/166 wrong=0 across six splits.
Also fixes a wrong-answer path this work uncovered in Band v1b
(ADR-0261 §5.1): `to_syllogism` FILTERED premises it could not express
out of the projection and answered from the remainder, so "Aristotle is
a philosopher. All philosophers are scholars. Therefore some scholars
are philosophers." lost its only witness and was served "that doesn't
follow". It now refuses — matching its propositional sibling
`to_deductive_logic`, which always has — and the argument falls through
to the bands that can hold a singular fact. The categorical band
re-earned SERVE 720/720 after the change; both examples are pinned as
regression cases.
Promotion: `ds-mem-0020` declined -> unknown (ADR-0258's existential
scope-out, now read; an anonymous witness never transfers to a named
individual, so UNKNOWN is its honest verdict, not entailed).
[Verification]: core test --suite deductive 232 passed; reader tests
33/33; register+surface tests 52 passed; arena 25 bands x 720 wrong=0
(all SERVE); lane 166/166 wrong=0; lane SHAs 9/10 match (public_demo
drift is pre-existing on the base commit and unrelated — evidence in
the Tier-S brief).
Generalization arc Phase 1.1 (Tier F, docs/plans/generalization-arc-2026-07-24.md):
"All philosophers teach. Socrates is a philosopher. Therefore Socrates
teaches." now reads and decides — the ADR-0258 §6.3 verb-predicate
scope-out, and the reading gate for Phase 2's subject serving.
generate/proof_chain/verb.py extends v3-MEM's per-individual lowering with
a second atom family in one shared space: membership atoms (v3-MEM's own
parsers reused verbatim) + verb atoms (individual, verb-lemma-group,
object-term). Verb universals instantiate as mem(i,C) -> [~]verb(i), so a
copula-minted membership fact discharges a verb rule. The ONE new semantic
identification is closed 3sg agreement (verb-specific irregular table +
the three regular suffix rules — deliberately NOT the noun table, which
would misroute "lives"/"leaves"). Scope-tight segmentation: single-token
name/class/verb/object shapes only; everything longer refuses typed
(tense_out_of_band joins the closed reason vocabulary). Rendered by
render_entailment_verb (member surface, UNKNOWN scoping extended to the
verb reading). Rides deduction_serving_enabled (default off); pure
widening — every previously-served argument byte-identical, no existing
lane case changed outcome.
Earned: 4 en_verb_* bands x 720 arena wrong=0 (first seal), ledger resealed
at 21 bands; corpus soundness asserted against the independent truth-table
oracle over each template's intended lowering (15,120 cases, INV-25).
Lane: v2_verb 28 hand-authored real cases 28/28 first run; full lane
134/134 wrong=0 across five splits. Surgical single-line pin update +
CLAIMS regen.
Stacked on feat/generalization-phase0 (merge that first — shared
verify_lane_shas.py / CLAIMS.md / generate_claims.py lane-ADR mapping).
[Verification]: verb reader tests 34/34; deduction battery 86/86
(surface +5, e2e +1, lane +1) in-worktree; arena seal + oracle
cross-check green; smoke + warmed_session via pre-push gate.
Plan of record for the generalization arc lands here
(docs/plans/generalization-arc-2026-07-24.md) with the risk-tiered
handoff pack (docs/handoff/generalization-2026-07/); Phase 0.1 executed.
Root-caused the three stale lane pins (docs/research/lane-drift-
investigation-2026-07-24.md):
- miner/curriculum: 5c69b741 (ADR-0244 §2.7) widened content digests
16→64 hex; intentional, pins were simply never updated. Re-pinned
surgically; SHAs triple-run deterministic.
- demo_composition: a REAL serving regression. #76's canonical-first
base precedence in resolve_surface, activated when #96 routed pipeline
turns through the resolver, served the pre-R6 canonical — the register
axis (ADR-0077 R6 substantive + ADR-0071 R4 decoration) was silently
stripped from every pipeline-served turn. T13's back-stamp then made
telemetry mirror the stripped bytes; register-tour claims went red and
the e2e tests pinning the axis (outside smoke) were failing on main.
Fix: response-first base precedence (served bytes = post-guard, post-R6,
post-R4) + new SurfaceResolution.hash_surface carrying the truth-path
canonical-precedence bytes through substrate overrides, folds, hedge,
logos-morph, and the speculative marker. compute_trace_hash folds
hash_surface, so the register axis varies the served surface ONLY and
trace_hash stays register-invariant (ADR-0069 inv C). _prior_surface
(correction binding) stays on the truth path. Dead FailureClass import
and _assessment_residual removed.
Also: generate_claims.py had raised on every run since the
deduction_serve_v1 pin landed without a _LANE_ADR entry — mapping added
(ADR-0256), CLAIMS.md regenerated, --check green.
[Verification]: register tour 6/6 claims (substantive-differs restored,
all_trace_hashes_identical held); 88 tests green in-worktree
(test_surface_resolution incl. 2 new fallback tests,
test_register_substantive_consumption incl. previously-red e2e tests,
test_grounded_open_hedge_arm, test_cognitive_turn_pipeline,
test_warmed_session_lane 10/10 T13 consistency); miner/curriculum lane
SHAs byte-identical across three runs; deduction_serve + deductive_logic
lane reports byte-identical to their unchanged pins; smoke suite via
pre-push gate.
Composes v2-EN's connective grammar (if/then, or, and, either) with
v3-MEM's singular-membership sentence reading over one shared
per-individual atom space, so "If Socrates is a man then Socrates is
mortal. Socrates is a man. Therefore Socrates is mortal." decides — the
exact gap ADR-0258 §6.1 reserved. Genuinely fuses the two mechanisms: a
bare universal's instantiated atom can unify (via the same closed
morphology relation) with a connective leaf's atom, deciding arguments
neither band alone could.
- generate/proof_chain/cond_member.py: new reader. A sentence is checked
for a connective token BEFORE the universal-lead check (so a stray
connective can never leak into an opaque name/class run); reuses v3-MEM's
own _parse_singular/_parse_universal verbatim (already negation-aware,
so no separate negation layer is needed, unlike v2-EN's opaque minter).
Four new shape-bands (fused/disjunctive/chain/conditional), each earning
its own SERVE license.
- chat/deduction_surface.py: new fallback tier tried strictly after v3-MEM
— pure widening, every previously-served argument stays byte-identical.
- evals/deduction_serve/practice/gold.py: 4 new synthetic template groups
(20 templates), reusing the v3-MEM case generator; intended formulas
cross-checked against the independent oracle (INV-25).
- evals/deduction_serve/v2_condmem/: 26 hand-authored real-English cases,
content-disjoint from the synthetic corpus.
- ds-mem-0024 promoted declined -> unknown (not entailed — the antecedent
is never asserted in that text; this is the first promotion in the
corpus that doesn't land on entailed).
- Ledger re-sealed to 17 bands; deduction_serve_v1 lane SHA re-pinned
(surgical single-line edit, not a blanket --update).
Verification: core test --suite deductive 160 passed (31 new reader
tests); practice arena 17 bands x 720 wrong=0, all SERVE-licensed; lane
splits v1 28/28, v2_en 26/26, v2_member 26/26, v2_condmem 26/26; smoke 180
passed; warmed_session 10 passed. Flag deduction_serving_enabled stays
default-off.
CORE now decides natural-English deductive arguments end-to-end:
'If it rains then the ground is wet. It rains. Therefore the ground
is wet.' -> ENTAILED, rendered over the user's own clauses. Both of
ADR-0256's documented boundary cases (multiword conditional, nested-
negation contraposition) are now decided; their lane gold updated
declined->entailed.
- generate/proof_chain/english.py (new): closed function-word grammar
over OPAQUE clause-atoms (minted ids); if/then, [either] or, and,
three negation forms (leading not / sentential / copular incl.
contractions); typed refusals; honesty caps. Soundness: positive
verdicts are substitution-closed; UNKNOWN is scoped + guarded
(quantifier-led, is-a membership, unnormalizable negation refuse
out of the opaque band).
- render_entailment_english: verdicts quoted back verbatim; UNKNOWN
phrasing explicitly scoped to the opaque reading.
- chat/deduction_surface.py: v2-EN fallback tier AFTER v1/v1b —
monotone widening, byte-identical on previously-served arguments.
- Four en_* shape-bands EARN SERVE via the ADR-0199 arena (720/band,
wrong=0, reliability 0.99087 >= 0.99); 9-band ledger re-sealed.
- evals/deduction_serve/v2_en: 26 hand-authored real-English cases
(content disjoint from the synthetic lexicon), wrong=0; report
re-pinned.
- realizer guard (ADR-0075): deduction surfaces exempt — quoted
templates are not slot-composed articulations (pack 'open'=VERB
was rejecting an honest quoted 'the door is not open'); pinned
cold+warm in e2e.
[Verification]: deductive 84 passed; smoke 180 passed; cognition 122
passed 1 skipped; arena 9x720 wrong=0 all SERVE; lanes v1 28/28,
v2_en 26/26.
core chat now decides Aristotelian syllogisms end-to-end -- the marquee
'basic logical work' widening. Closes Phase 0's fork: the ONLY categorical
decider was evals/syllogism/oracle.py (the sealed independence oracle serving
must not import; INV-25). This ships a production decider.
generate/proof_chain/categorical.py lowers a categorical argument to the
propositional regime (one Boolean atom per term-membership profile) and rides
the already-verified ROBDD engine -- no new decision procedure, soundness
inherits from the flagship. Sound AND complete for the modern/Boolean reading
(Darapti + existential-import-only forms correctly INVALID), with no reliance
on a lucky domain size. Independent of the eval oracle by mechanism (ROBDD-
over-profiles vs brute-force finite-model enumeration); proven by case-for-case
agreement with it across the whole syllogism gold lane.
New: generate/proof_chain/categorical.py, render_syllogism (deterministic
valid/invalid/inconsistent templates), CATEGORICAL shape-band, arena
categorical band (4 valid forms + 2 invalid, by-construction gold cross-checked
vs the independent syllogism oracle), tests/test_categorical_decider.py (8
tests incl. the independence-by-agreement proof).
Changed: chat/deduction_surface.py (categorical branch, license-gated via a
shared _license_gate helper; propositional path byte-identical), arena
DeductionSolver dual-path in lock-step with the composer, re-sealed ledger (5
bands, categorical earns SERVE at 0.99087 wrong=0), Phase-2 lane decide()
mirrors the dual path with the 3 categorical cases reclassified to their true
valid/invalid verdicts + 1 invalid case (n 27->28), report+SHA regenerated.
Honest wrinkles: irregular plurals ('fish') decline with unknown_morphology
(a reader limit, correctly not a wrong); surfaces read in singularized terms
('all whale are animal') -- the exact ids the engine reasoned over, no cosmetic
re-pluralization that could drift from the decision.
[Verification]: smoke 180 passed; cognition 122 passed/1 skipped; core test
--suite deductive 45 passed; test_categorical_decider 8 passed; practice
runner 5 bands all SERVE wrong=0; deduction_serve lane SHA regenerates to the
committed pin.
New evals/deduction_serve/ lane scores the PRODUCTION serving decider
(the exact comprehend -> to_deductive_logic -> evaluate_entailment_with_trace
pipeline chat/deduction_surface.py runs) end-to-end from raw text --
distinct from evals/deductive_logic (bare engine vs formula strings) and
evals/comprehension/propositional_runner.py (reader fidelity vs the
independent oracle, not the production engine). This is the only lane
proving the capability core chat actually serves.
27 hand-authored cases (gold computed by independent logical reasoning,
not copied from a first engine run), 4 classes: entailed/refuted/unknown/
declined. 27/27 correct, wrong=0. Wired into core test --suite deductive
(tests/test_deduction_serve_lane.py) and SHA-pinned in
scripts/verify_lane_shas.py (deduction_serve_v1).
Honesty check during authoring: a case intended as 'entailed'
(contraposition, 'Therefore if not q then not p') actually declined --
tracing why found a genuine reader-grammar boundary (negation cannot
nest inside an if/then clause; generate/meaning_graph/reader.py's _chunk
rejects it). Reclassified to declined/out_of_band_nested_negation
(documented in contract.md) rather than forcing an artificial pass, and
added a replacement entailed case (three-hop chain) to keep coverage.
Out-of-scope finding (documented, not fixed here): running
scripts/verify_lane_shas.py --update to compute this lane's pin also
re-executed every OTHER registered lane and surfaced two pre-existing,
unrelated problems on main -- miner_loop_closure/curriculum_loop_closure/
demo_composition regenerate non-deterministic content IDs (their
committed pins don't reproduce even on a clean checkout), and public_demo
errors outright (matches the known env-timeout flake in project memory).
Reverted all four lanes' results/*.json and PINNED_SHAS entries to their
original committed values -- this PR's only PINNED_SHAS change is the new
deduction_serve_v1 entry.
[Verification]: smoke 180 passed; cognition 122 passed/1 skipped;
core test --suite deductive 25 passed; evals.deduction_serve.runner
27/27 wrong=0; pinned SHA independently re-verified against the
committed report.json bytes.
2026-07-23 directive: instrument candidates-proposed-per-served-turn on
clean, post-reset traffic. Adds an additive-optional turn_count_baseline
manifest field (engine_state) stamping the turn_count at the last clean
reset of the discovery-candidate ledger, a pure compute_discovery_yield
function (teaching/discovery_yield.py), and a read-only `core teaching
discovery-yield` CLI surface. Fails closed (returns None / exits 1) when
no baseline has been stamped rather than fabricating a denominator.
scripts/ops/stamp_discovery_yield_baseline_20260723.py stamps the T11
reset epoch into the live store, mirroring reset_candidate_corpus_t11's
atomic generation-dir pattern. Dry-run verified against a throwaway copy
of the live store's gen-21703; not yet executed against the real store
(see PR body).
Weekly-audit 2026-07-22 closeout — T13 decision (3) CI gate + T11 execution.
- scripts/hooks/pre-push + install.sh: a core.hooksPath pre-push gate that runs
the smoke suite PLUS the warmed_session consistency lane pin — the T13
telemetry-consistency regression class that smoke does NOT cover. The full
~12k fast-lane stays async CI by design; the gate is deliberately targeted so
it blocks the regression class without gridlocking pushes. Fail-closed on
empty stdin; skips deletion-only pushes; emergency bypass git push --no-verify.
- scripts/ops/reset_candidate_corpus_t11_20260722.py: provenance record of the
T11 live-store reset. The 465 discovery candidates predated the #100
isolation fix and carried no per-record test/prod discriminator, so a surgical
quarantine was impossible; ruling was to clear (not asterisk). Executed as an
ADR-0219 atomic generation reset (empty candidate ledger, keep=1) — candidates
465 -> 0, turn_count 14990 and identity lineage preserved, tainted generations
GC'd. Data lives in gitignored engine_state/; this script is the audit trail.
- AGENTS.md: document the automated pre-push gate under the Local-First CI
Validation Protocol.
- weekly-audit ledger: T10 merged (#100), T11 ruled+executed, T13 (2) hedge-arm
ruling + (3) pre-push gate recorded.
[Verification]: smoke 180 passed (132.9s) + warmed_session lane 10 passed
(140.5s), exit 0 — worktree core-wt-infra @ base 9a428d84.
The inverted-seed P2 regex treated optional "times" as optional, so
additive "8 more" on multi-entity zoo case 0361 extracted as pure S1 and
the three-gate corridor emitted 1.125 vs gold 114.0 (wrong≠0).
- Require explicit multiplicative surface (times as many / twice the …)
- Fail-closed purity gate: multi-clause markers, multi-numeric, multi-mult
- Regression tests for 0361 and bare "N more"
- measure --mode full-holdout-wrong0 over all 500 holdout cases
[Verification]: full-holdout emit_ok=9 wrong=0 refused=491; unit 37 passed
Increment 2 for ADR-0252 Track B. Extends Increment 1's structure-mapping
slice with pure-family canonicals S2–S4, overlapping-waves selector, and a
structure-mapping-owned pure-S1 text extract that recovers four real
holdout cases the serving reader misses (0148, 0228, 0234, 0441).
Bar results (command-backed via scripts/measure_trackb_inc2.py):
- generalization ratio S1 = 9.0 (9 holdout cases / 1 template)
- coverage gain organ 5 → trackb 9, wrong=0
- selector routes S1/S2/S3; refuses empty; surface≠structure
Off-serving: no organ retirement, serving reader untouched. S2–S4 holdout
ratios are 0 (parser frontier). S3/S4 emit refuses at multi-register scope
without weakening the three-gate wrong=0 path.
[Verification]: Smoke suite passed locally (~132s, 176 passed);
trackb unit tests 35 passed; measure_trackb_inc2 all modes green.
ADR-0252 §5 geometric SME is NO-GO; this is Track B Increment 1.
Adds role-predicate conversion from MathProblemGraph, S1 canonical skeleton,
blind symbolic mapper (match/refuse + binding), and solve via classical
verify plus multi-register certificate. Research report and holdout measures
included. Serving reader unchanged; no S2–S4 generalization.
lane-shas.yml has intermittently failed under Act-runner contention with
truncated/ambiguous logs (see docs/plans/adr-0241-0242-session-completion-
summary-2026-07-15.md #38 postmortem: run #167 failed at ~22m39s, but local
verify_lane_shas.py showed 9/9 pins matching — the failure was never
conclusively attributed to a timeout vs an incomplete log, because the
script buffers all per-lane output until every lane finishes).
Two changes, no lane logic touched:
1. Stream progress per lane (`-> lane_id ... done (Ns)`, flush=True) instead
of buffering until the end, so a hang shows exactly which lane and for
how long even if the job is killed before the final summary prints.
2. Make the per-lane subprocess timeout configurable via
CORE_LANE_VERIFY_TIMEOUT_S (default unchanged at 900s — same knob shape
as CORE_SHOWCASE_HARD_BUDGET), and report a TimeoutExpired distinctly
from a genuine SHA mismatch so the remediation text stops suggesting
`--update` (re-pinning) for what is actually runner contention.
[Verification]: tests/test_lane_sha_verifier.py 6 passed; ruff clean;
scripts/verify_lane_shas.py run locally with the new streaming output
confirmed correct per-lane timing (e.g. demo_composition 154s) end to end.
Root cause of demo_composition pin thrash was not cancelled CI runs:
verify_no_global_state_mutation dumped full env_subset before/after
tuples into the lane report, embedding CORE_ENGINE_STATE_DIR temp
paths (and any ambient CORE_* host values). Each hermetic run then
produced a different report SHA.
Fix for good:
- Report key-level env deltas only (+/- / changed), with path-like
CORE_* values redacted to <path> in the message text.
- Detection still uses raw snapshots (mutations are not ignored).
- Hermetic CORE_ENGINE_STATE_DIR for demo_composition and all
verify_lane_shas invocations.
- Dual-run-stable re-pin: demo_composition e2ba2314…,
public_demo 7d8ba0db… (matches CI-observed soft-budget SHA).
- Drop dead CORE_SHOWCASE_SKIP_BUDGET workflow env (soft is default).
- Tests pin the delta format and hermetic-path stability.
Lane: python scripts/verify_lane_shas.py → 9/9 match.
* feat(bench): add Apple UMA demo package builder
* test(bench): cover Apple UMA demo package builder
* docs(outreach): add Apple UMA demo package runbook
* feat(bench): harden Apple UMA demo package workflow
* feat: implement kernel substrate tranche 1 base-layer foundations
* fix(kernel): ground scalar spans and tighten morphology labels
Add extract_scalar_candidates() with exact source spans and problem_text
provenance while keeping canonicalize_scalar() as the detached pack helper.
Morphology labels now emit missing_* only when substrate frame/unit lookups
actually fail, not on mere trigger-surface presence.
Introduce deterministic practice-memory infrastructure that adapts sealed
scout output into compact, retention-gated ExperienceRecords with family,
hazard, and promotion-candidate summaries. No serving, corpus, pack, or
report.json mutation — measurement-only adapter for future sprint reuse.
Gate A1 and related cognition-path changes shifted the showcase
determinism fingerprint (86db25b6…) while the lane pin still reflected
the pre-drift artifact (e323adb3…). Re-pin to the CI-verified SHA
2895df08… and refresh v1_dev.json + CLAIMS.md.
Hermetic demo hygiene: use no_load_state for register-tour, learning-
loop, and multi-hop showcase adapters, and isolate CORE_ENGINE_STATE_DIR
in the public_demo lane runner so local engine_state/ pollution cannot
affect eval output or wall-clock.
* feat(derivation): Workstream A inc 2 — frontier report + rate_with_currency apply_rate injection
- scripts/gsm8k_frontier_report.py + test (stable buckets; rate_with_currency surfaced)
- docs/recognizer-registry.md + math_candidate_graph.py comments repaired (current refusal doctrine; old skip-only marked historical)
- generate/math_roundtrip.py: add 'a','an' to RATE_ANCHORS (with doc update)
- generate/recognizer_anchor_inject.py: inject_rate_with_currency (narrow ProperName actor, Rate/apply_rate CandidateOperation, rejects unsafe); registered in _INJECTORS; module docs updated
- tests/test_*_rate_injection*.py + frontier test (8+ unit cases, confusers, synthetic wiring, real-report frontier pin)
- ratification doc (pre-code)
- lookback (post-impl, truthful)
All required local commands exercised (pytest green for new + prior extract/invariants; frontier script shows rate bucket; runner per brief; shas captured).
wrong=0 held. No sealed movement. Proxy still expected !passed (correct_min=10).
See ratification and lookback for scope, hazards, exact outputs.
* fix(derivation): dollar grounding, roundtrip proofs, stale comment, lookback commit, a/an containment, duplicate import
- math_roundtrip: add explicit 'dollar'/'dollars' + '$' branch in _unit_grounds (symmetric to cent) + doc alignment.
- tests: assert roundtrip_admissible True for the emitted rate cands; add a/an containment/confuser test (dollar unit only grounds with $ present); add lower-level _apply_rate solver reach test; remove conditional happy-paths that tolerated refusal; clean duplicate __future__.
- math_candidate_graph: update active stale comment (injector-empty now leads to explicit refusal, not drop/preserve-zero).
- Commit the Inc2 lookback (was local-only).
All per lead block list. New head will be pushed.
* fix(derivation): address remaining Inc2 blockers (locate_rate_verb via matcher token, dispatch test, lookback accuracy, narrow symbols, tests)
- recognizer_match: updated _CURRENCY_AMOUNT_RE + parsing to populate 'rate_anchor_token' localized to the rate span (prevents whole-sentence 'a' hazard from 'a lemonade stand').
- recognizer_anchor_inject: use 'rate_anchor_token' from anchor (with allowed-set check); fallback only if absent. Added Alexa-style confuser coverage.
- injector: narrowed _CURRENCY_SYMBOL_TO_UNIT to $ only for Inc2.
- tests: strengthened dispatch to require live-registry non-empty + roundtrip_admissible; added rate_anchor_token confuser test proving 'per' (not earlier 'a') is used; roundtrip asserts already present.
- lookback: updated to 10 files, 10+6 test counts, current head reality, shas/runner status exact, no rebaseline.
- math_candidate_graph comment already corrected in prior.
All Semantic Rigor / wrong=0 invariants preserved. New tip after push.
* fix(inc2): remove rate fallback to _locate_rate_verb; mandatory rate_anchor_token; hard 'for one cup' confuser; strengthen per-span test; update lookback
- injector: for currency_per_unit_rate, rate_anchor_token is now mandatory. Absent or invalid → immediate return ().
No call to _locate_rate_verb for these anchors.
- tests: _rate_anchor helper now passes rate_anchor_token.
- Added hard confuser test for 'Alexa ... for one cup.' — live registry + inject_from_match must emit ().
- Strengthened distracting-a ' per' test to unconditional: m not None, RATE_WITH_CURRENCY, len==1, matched_verb=='per', roundtrip_admissible True.
- lookback updated for 11 files, include matcher.py, rate_anchor_token centrality, exact counts after this.
* docs: pin exact final SHA in Inc2 lookback

Read-only /logos frontend route (Wave M CORE-Logos read-only wave, LG-2):
- route registered via WORKBENCH_ROUTES + lazy ROUTE_ELEMENTS (Substrate section)
- Overview / Identity / Safety tabs over live /logos/packs, /{id}, /safety only
(no /contents or /alignment — those are LG-3 / LG-4)
- 10 Logos* TS interfaces mirrored; NOT_YET_MIRRORED shrunk back to empty
- SafetyVerdict UI badge + dump-enums.py source + enum-snapshot + coverage test
- logos_pack evidence subject (logos:<pack_id>) + round-trip
- bottom strip "proposal mode: none — read-only"; holonomy rendered as
missing_evidence (no tab, no proof card); invalid alignment targets surfaced
honestly in Safety; verdict never mapped to "clear" for warning/unknown
Depends on LG-1 (#737). No mutation endpoints, no engine math in the UI.
scripts/workbench — a single robust entrypoint so a fresh clone runs the
Workbench the FIRST time, not sometimes:
- doctor: fail-loud preflight (uv, node>=20, pnpm via corepack, curl) — each
failure prints the exact fix, never a half-started UI
- setup: idempotent — uv venv + editable CORE install + pnpm frozen install,
only when actually missing; re-runs instant
- up: health-gated start of the stdlib API (:8765 /health) + Vite UI (:5173),
reuses already-healthy ports, invokes vite directly so Ctrl+C tears down
both cleanly (TERM-then-KILL, EXIT trap); logs to /tmp/core-workbench-*.log
- pure-Python backend (numpy) — no Rust build required to run the Workbench
- API_PORT / UI_PORT overridable
Tested end-to-end: up in ~5s (API /health 200, UI 200), clean teardown
frees both ports. README gains a 'CORE Workbench — one command' quick-start
as the most-discoverable visual entry, with the first-time-works guarantees
spelled out for an external evaluator.
First R3 (Theater) piece. Reworks the stale artifact-keyed ReplayRoute into
the turn-keyed hero over the #716 sealed-replay backend, and fully retires
the dead W-026 artifact-keyed machinery on both sides (the NOT_YET_MIRRORED
comment anticipated this).
The hero makes determinism *felt*: pick a journaled turn, CORE re-executes
its prompt in a sealed fresh runtime, and the result renders as a hash
verdict (≡ equivalent / ≠ diverged) + the original/replay DigestBadges + a
leaf diff (critical weighted above informational, each with a ≠ glyph). The
'What this proves' card surfaces comparison_basis + origin_state and states
the honest limit: a divergence means nondeterminism OR origin-state
influence, never rendered on its own as a determinism failure.
Retirement (verified zero serving uses):
- Python schemas.py: removed ReplayComparison/ReplayDivergence/ReplayStatus/
ReplayDivergenceSeverity; scripts/dump-enums.py drops the two replay enums;
both snapshots regenerated (deterministic: dump == committed)
- TS: removed ReplayComparison/ReplayDivergence/ReplayDivergenceSeverity;
added TurnReplayComparison/TurnReplayDivergence (+ basis/origin/severity
unions); NOT_YET_MIRRORED now empty (every engine schema mirrored)
- badges: removed ReplayStatusBadge + ReplayDivergenceSeverityBadge +
meta/enums + their enumCoverage cases (hero renders severity inline)
- api: fetchReplayComparison/useReplayComparison -> fetchTurnReplay/
useTurnReplay (/replay/<turnId>)
- deleted ArtifactList, ReplayComparisonPanel, ReplayDiffViewer,
ReplayMetadataTable, old replay.test.tsx
- App route /replay/:artifactId? -> /replay/:turnId?; conformance row
turn-keyed (loading 'Loading turns...', empty 'No turns recorded yet.')
Tests: ReplayRoute.test.tsx (equivalence hero + honesty card, diverged
critical leaf, informational-only label, replace-mode select, j/k spine).
Full vitest 358 green; workbench Python 34 green; both snapshots deterministic.
Follow-up flagged (not in this PR to keep it focused): the artifact query
hooks (useArtifacts/useArtifactDetail/fetchArtifacts*) are now orphaned but
entangled with the still-live artifact EvidenceSubject kind — a separate
cleanup once an Artifacts route or that subject's fate is decided.
Brief: docs/handoff/wave-R3-briefs-2026-06-13.md (all four R3 pieces).
- EvidenceChainRail: the spine's seven stages rendered per subject with
the honesty contract — lit/hollow/dim derive ONLY from carried fields
(a trace hash lights 'replay' as RECORDED, never as verified); pure
deriveStages() with meaningfully-fail tests (remove one field -> exactly
its stage hollows).
- Hash display standard: DigestBadge default 12-char + copy everywhere;
CopyableHash consolidated away (2 call sites swapped, file deleted).
- Typography: tabular-nums on MetadataTable values + eval metrics;
text-wrap balance on Panel titles + EmptyState statements.
- Selection unification: new --color-selected-bg/-border tokens; selected
(persistent) vs focused (transient) now visually distinct across
Proposals/Replay/Evals lists; focus-ring no longer doubles as selection.
- EmptyState gains a deterministic monochrome inline-SVG glyph.
- Panel adopted in Evals lane list + Proposals queue.
- Doctrine-as-tests: hexScan (no palette literals outside tokens.css/
generated tokens.ts) + schemaDrift gate (scripts/dump-schemas.py AST
walk -> schema-snapshot.json -> every dataclass field mirrored in
types/api.ts; explicit shrink-only NOT_YET_MIRRORED debt list).
The drift gate caught real drift on first run: ChatTurnResult.turn_id
existed in Python, missing from TS — now mirrored.
Verified: build green; vitest 36 files / 279 tests EXIT=0; playwright
12/12; dump-schemas.py runs clean.
ADR-0184 S4b — the replay/provenance equivalence boundary, the
precondition for any semantic-primary path. After #685 the in-repo
legacy path delegates to the semantic boundary, so old-vs-new is
vacuous; the durable reference is a pinned canonical trace artifact
(evals/gsm8k_math/equivalence/v1/, 937 problems) whose authority is
the #684/#685 cross-tree differentials (documented provenance chain).
- state/provenance.py: replay_is_faithful — the replay bridge's law as
a checkable structural property (no verify/pool import; covered by
the #685 authority scan).
- equivalence/trace.py: canonical traces (worlds, candidates, order,
multiplicity, classifications, resolutions) + authority_violations
re-deriving the pool commit law from trace content.
- scripts/verify_semantic_equivalence.py: check / --update gate
mirroring verify_lane_shas.py.
- tests/test_adr_0184_s4b_replay_equivalence.py: full-corpus live-vs-
pinned equality, corpus-wide authority + faithfulness, and 17
single-mutation non-vacuity proofs.
Pure additions; verify.py/pool.py untouched; no serving, CLAIMS,
metrics, or lane pins moved.
