The branch was re-created with SSH signatures before landing, which changed my
commit SHAs. Four citations of the pre-registration commit — the verdict's
header and closing note, G-1, and the plan's Track A section — pointed at
dfc394d2, which is not in main's history. They now point at 299c92be, which is.
Same tree, same message, same ordering, signature added. The claim the verdict
rests on is unchanged and checkable at 299c92be: that commit contains the
thresholds and no results. Recorded as a note in the verdict document rather
than swapped silently, because a document citing a commit absent from its own
repository's history is precisely the failure mode its §1 catalogues — and this
one would have been self-inflicted.
Docs only.

53 cases, 1378 pairs, 0.0% non-convergence — no exception contributed to any
number. RS-A (structure-only) separates perfectly, AUC 1.0000, margin +0.0867,
and fails structure-sensitivity. RS-B (attribute-bearing) fails all three.
The mechanism, measured rather than argued: the similarity quotient that would
deliver attribute-invariance is the same quotient that annihilates structural
contrast. An add-vs-subtract minimal pair — one entity, identical numbers, one
relation kind changed — aligns at residual exactly 0.0, its two configurations
being related by a PROPER rotation about e1. Sweeping the attribute weight
(committed as diagnostic_sweep), structure-sensitivity fails at every setting,
and every regime where the SME property survives is a regime where attributes
contribute nothing: AUC 1.00 -> 0.97 -> 0.83 -> 0.69 as they begin to matter.
Scope stated narrowly: this refutes H1 for embeddings that encode role-structure
as point positions aligned by conformal Procrustes under similarity. The
argument is about the quotient, so it generalises across that class; it does not
refute every Cl(4,1) representation, and it does not touch the symbolic
structure-mapping lane already in evals/structure_mapping/.
Two findings that were on nobody's list:
N-8 — the experiment was NOT unrun. rnd/sme-experiment-v2 @ 96e5f468 is titled
"Verdict: GO" and rnd/structure-mapping-experiment @ fc9d0c14 carries an earlier
one. Neither survives inspection: attempt 1 leaked the S1-S4 label into the
embedding; attempt 2 was blind and then took its separability from
`except ValueError: res = 1000.0` — a solver exception counted as a distance —
on a corpus 46/51 of which is outside holdout_dev/v1 with nothing marked, with
duplicate graphs, colliding ids, and an extractor that was never committed. The
register, the plan and the ADR all read the same absence and inherited the same
error for nine days. A branch tip is not a record.
G-21 — the math reader returns a selected graph for 5 of 500 holdout_dev/v1
cases (1.0%), all one skeleton; 24/150 on the public lane. That is why §5.1's
four-structure corpus is not extractable, and it is a sharper measurement of the
comprehension frontier than G-3's construction count.
Registers updated: G-1 carries the verdict, H-10 confirmed and discharged, G-21
added, plan §0 gains N-8, Track A closed, synthesis frontier 2 rewritten.
Pins: tests/test_adr_0252_s5_blindness.py, each observed red before green
(label leak and duplicate-graph sabotage both caught).
Off-serving — evals/structure_mapping/adr0252_s5/ is imported by no serving
path, emits no answers, and changes no flag.
[Verification]: 797ebad5 + this branch — `uv run core test --suite smoke -q`
641 passed in 199.76s; `uv run ruff check` clean; report regenerated after lint
with an unchanged digest.
Track A, per 50-execution-plan.md §6: "state the GO/NO-GO criterion in writing
BEFORE running (the ADR's §5 conformance bar, not a criterion chosen after
seeing results)." This commit carries the criterion and the code and NO results.
Why the protocol is load-bearing here rather than ceremonial: the §5 experiment
is not unrun. It has been run twice and returned GO twice, on unmerged branches,
and neither run's rule was binding.
- rnd/structure-mapping-experiment @ fc9d0c14 — disowned by its own successor:
the S1-S4 label entered the embedding, so Procrustes ran on identical
matrices per structure.
- rnd/sme-experiment-v2 @ 96e5f468 — blind, and then measured separability
with `except ValueError: res = 1000.0`. Its GO test cross_mean > 2*same_mean
is satisfied by that sentinel alone. A solver exception is not a distance.
Instrument characterised before use, on dummy clouds: conformal_procrustes has
two branches. The (5,K) Kabsch+Umeyama path never raises and is invariant to
rotation, translation AND uniform scale (identical 1.8e-16, rotated 7.8e-16,
translated 3.9e-15, scaled x2.5 1.4e-14) while separating non-similar
deformation (5.9e-1) and unrelated clouds (1.1e0). The mixed versor/point
sequence path performs field conjugacy and raises. Attempt 2 used the second;
this uses the first, and treats a raise as non-convergence — excluded, reported
as a rate, never counted as separation.
Corpus fact that forced the design, measured at 797ebad5: the serving reader
returns a selected graph for 5 of the 500 holdout_dev/v1 cases (1.0%), all with
the same skeleton. §5.1's four-structure corpus is not extractable from
holdout_dev/v1 today, so §5.1's own escape hatch is used and MARKED — 5 real
cases, 48 synthetic from four declared templates. A verdict from this corpus
speaks about the geometry, not about coverage; §5.5's compression estimate is
not answerable at 1.0% coverage and is not attempted.
Off-serving. Imported by no serving path; no answers emitted.
The corrections derived in 50-execution-plan.md §0, applied where the wrong
claims live. Every amendment is marked [AMENDED N-x] inline so the register
carries its own correction history rather than quietly reading correct.
Gap register — four entries amended:
- G-5 the soak RAN and passed (5000 beats, reboot at 2500, all four gates,
aed273b1). Retitled: what is owed is the committed artifact, the pinned
deterministic_digest, and a cadence — not the run. Both prior claims
withdrawn with their causes: "no suite contains any l10 test" was a
scan artifact (TEST_SUITES["full"] is a directory), and the pins
execute twice a day (post-merge + nightly cron).
- G-7 respecified. The proposed meta-check was already satisfied and would
have shipped green proving nothing — a hollow gate in the entry
proposing to abolish hollow gates. Now two pins: gate parity, and
curated-suite membership EXCLUDING full.
- G-8 28 default-off flags of 32 RuntimeConfig booleans, not seventeen.
- G-10 the 16-premise cap was removed by ADR-0264 R5 on 2026-07-26; the ADR
carries a self-supersession banner directly under the heading Phase 4
quoted. No engineering prerequisite remains — R-8 alone gates it.
- G-19 note: the 21/25 exposure is already pinned in test_volume_honesty.py,
so the work is applying the demotions, not discovering them.
Hindrance audit:
- H-12 added — the local smoke suite (23) and smoke.yml (13) have diverged by
ten files. Counter-evidence stated first: AGENTS.md makes the local run
the merge gate and it is the superset, so nothing is unguarded. What is
real is one comment claiming an equality that does not hold, and the
push that skipped the local gate.
- H-8 gains instance (d), inside the code: two flag docstrings assert a
production profile CONTINUOUS_LIFE_CONFIG_FLAGS does not have.
- H-1 gains the already-pinned note.
Also: correction note on the 2026-07-25 verification doc (a corrective
document that introduced the error at H-8c), and a staleness banner on
MIND-PHYSICS-BLUEPRINT.md pointing at the taxonomy that dissolved it.
The two ratified-ADR amendments (ADR-0146, ADR-0252) are NOT here — they are
drafted in full in 50-rulings.md R-12 and land on that ruling, because editing
a ratified ADR is Shay's authority even when the edit changes no decision.
Docs only. No runtime behavior, no flag, no test changed.
Plan §6A, report-only per DIVISION-OF-WORK §4. Both halves ran. The cargo half
is real evidence; the LANE half is vacuous, and saying so is most of the point.
cargo test (PYO3_PYTHON=/opt/homebrew/bin/python3.12, --offline): 43 passed,
0 failed across 7 suites including test_crdt_hash_parity.rs. The plan's read
was right — cargo 1.97.1 and the registry cache are present locally and the
cloud session was blocked only by sandbox network policy.
Lane parity: 11/11 pinned SHAs match under both backends. That number means
nothing. Sabotaging EVERY core_rs callable to raise and re-running under
CORE_BACKEND=rust still gives `lanes: 11/11 match pinned SHAs`, exit 0. Three
sufficient reasons:
- The hot path bypasses the dispatch. algebra.cga.cga_inner is NOT
algebra.backend.cga_inner; 69 call sites import the hot functions from
algebra.cga/algebra.cl41 directly vs 24 through algebra.backend. The ~34k
cga_inner->geometric_product calls/turn that plan §6C calls ~73% of turn
time never reach the dispatch.
- The dtype gates reject the runtime workload. versor_condition IS imported
from algebra.backend by pipeline.py:24, and still falls through: the Rust
arm requires f32 and the wave-field workload is f64.
- Every dispatch arm ends in `except (..., Exception): pass`, so a broken,
garbage-returning, or absent kernel falls back to Python SILENTLY. That is
what makes the first two unfalsifiable by lane hashes.
Instrumented under CORE_BACKEND=rust: zero Rust calls in the whole
deductive_logic lane (pure ROBDD, no CGA), and exactly ONE
(versor_apply_with_closure_f64) in a full pipeline turn. CORE_BACKEND=rust is
today a one-call switch.
So §6B ("if parity holds, consider Rust default") rests on a measurement that
cannot fail, and §6C is the real blocker and is upstream of the backend. NOT
acted on — §6.4 says a parity/determinism finding is escalated, not fixed.
Recorded three follow-ups in dependency order: make the dispatch fail loudly,
add a parity test that fails when the Rust path is not TAKEN, only then route
the hot path.
The one thing fixed here is a plain defect blocking the measurement.
`core rust build` — the activation path print_rust_status() itself recommends —
raised `TypeError: _run() got an unexpected keyword argument 'env'` on every
invocation. core/cli.py::_run is injected into cli_rust.cmd_rust_build, which
passes env=rust_build_env() to carry PYO3_USE_ABI3_FORWARD_COMPATIBILITY, and
_run lacked the keyword the CommandRunner Protocol declares. One keyword, plus
tests/test_cli_runner_contract.py deriving the expected keywords FROM the
Protocol so the two cannot drift apart again. Verified end-to-end: `core rust
build` now builds and installs.
[Verification]: in-worktree on canonical CPython 3.12.13 with `uv sync
--locked`: smoke 575 (569 + 6), deductive 291 (unchanged). New tests fail
under mutation (revert the env keyword -> 3 red). Registered in `fast` AND
`smoke`. Installing core_rs does not activate it (_ALLOW_RUST requires
CORE_BACKEND), verified: extension present + no env var -> "rust backend:
inactive", so no default behaviour moves.
Builds the producer `chat/curriculum_serve_license.py` already named as the
only writer of the ledger it reads — `evals.curriculum_serve.practice.runner
.seal_ledger` — which did not exist. Until now, authoring curriculum could
not earn a license at any volume.
A band's case space is ENUMERATED, not authored: every exam question that
routes to that subject (resolve_domain) whose relation is in that family, one
committed case per distinct query atom. So `committed == distinct` is not a
property the generator maintains, it is the same fact twice — the structural
form of ADR-0264 R9, and why this producer cannot develop the deduction
producer's exposure (CASES_PER_BAND=720 filled from spaces as small as 28).
CASES_PER_BAND=660 follows `evals/determination_estimation` per
DIVISION-OF-WORK §4: a ceiling on committed volume, not a quota.
11 bands, wrong=0, inflation 1.0 everywhere.
THE LEDGER IS DELIBERATELY NOT COMMITTED. The plan's Phase-1 exit criterion
asked for "a real (still-unearned) ledger"; that state is unreachable.
Reliability is commitment precision and a correct UNKNOWN is a commitment, so
conservative_floor(660,660)=0.990046 clears theta_SERVE on non-commitments
alone. Sealing today licenses FOUR bands on evidence that is 99.0%-99.98%
correct non-commitment — which ADR-0262 §5.1 rules unacceptable and which
ClassTally structurally cannot see (no verdict axis). Writing the artifact is
therefore a ratification and belongs to Phase D's explicit human-run verb.
The open outcome-mix ruling is now blocking, not academic.
Two corrections to my own earlier records, both measured:
- ADR-0264 §4.2 sized bands from per-TERM exclusivity; the router's predicate
is per-PAIR, which is looser. Every ceiling was understated, and
systems_software_causal is 720 not 630 — flipping it from "cannot reach
657" to "can". 4 of 11 bands can reach the floor, not 3. Now pinned as
measured values in BAND_ATOM_SPACE.
- `then` and `therefore` are taught philosophy_theology lemmas AND control
words of the argument reader (`therefore` is the conclusion marker). 164
routable atoms refuse compiled_premises_unreadable — coverage misses, never
wrongs — in the band Phase F retargets to. The vocabulary boundary is not
screened against the reader's grammar; a pack teaching and/or/not/if would
open a much larger hole the same way. Recorded, not fixed (§6.5), pinned as
a two-lemma bound.
Registers curriculum_serve in AUDIT_SOURCES, retiring the declared `None`
that was Phase C's forcing function, and adds the producer to `deductive`.
[Verification]: in-worktree on canonical CPython 3.12.13 with `uv sync
--locked`: smoke 571 (569 + 1 test + 1 parametrization), deductive 310
(291 + 19). Mutation-checked: injecting the deduction padding pattern into
band_cases turns 5 tests red including the R9 audit and the seal guard.
curriculum_serve lane unchanged at n=32 correct=32 wrong=0 anti_recall=5;
all 11 lane SHA pins match; no ledger written, so no serving change.
Phase B of the curriculum-license-loop arc. Stacked on the ADR-0264 branch.
The invariant: conservative_floor is a one-sided Wilson lower bound and Wilson
assumes INDEPENDENT trials. CORE's pipeline is deterministic, so replaying an
identical case is not a second trial -- it is the same trial with a guaranteed
outcome. A ledger's `committed` count is an upper bound on its evidence; the
defensible figure is its distinct-decision count.
Phase B was scoped as a precaution for a curriculum producer that does not
exist yet. Running the instrument against the producers that DO exist found it
already violated:
21 of the 25 ratified deduction_serve bands do not clear theta_SERVE=0.99 on
distinct evidence. Three inflate 28 distinct cases into 720 committed
(honest floor 0.8084 vs claimed 0.9909). deduction_serving_enabled was
ratified ON 2026-07-24 and is live.
The estimation producer (ADR-0175) is clean -- 660 committed, 660 distinct,
zero repeats, evidently chosen just above the 657 a perfect record needs. So
this is a regression from a standard already established in the repo, not an
architectural gap. `claimed` is identical for all 25 deduction bands because
every band commits 720 with a perfect record: the gate sees 25
indistinguishable passes while honest floors span 0.8084..0.9909.
NOT REPAIRED. The ledger is SHA-sealed, ratified, and gating a live flag, so
re-sealing it is Shay's ratification, not a test's. wrong=0 still holds -- no
band answered anything incorrectly. What is not established is reliability at
the volume claimed. Measured, pinned in both directions, written down.
Added:
- core/reliability_gate/evidence.py -- pure measurement, imported by no serving
path. volume_for_theta() DERIVES 657 from conservative_floor rather than
restating it, so a WILSON_Z change cannot leave a stale literal behind.
- tests/test_volume_honesty.py -- 13 tests. AUDIT_SOURCES is checked against
CAPABILITY_LEDGERS, so a new licensed capability cannot ship unaudited; the
curriculum entry is a declared None that fails the moment its ledger exists.
That is Phase C's forcing function against repeating the pattern.
- docs/research/distinct-evidence-audit-2026-07-25.md -- full audit + the open
outcome-mix ruling for Shay.
- ADR-0264 R9 amended with the measured exposure.
Decision key is case TEXT deliberately: a tighter key (normalized atom) would
collapse spelling variants and report MORE inflation, so text-identity
under-reports and every number is a floor on the real gap.
Outcome mix is deliberately NOT pinned. ClassTally has no verdict axis, the
deduction producer already balances 240/240/240 by construction, and imposing
a per-verdict-class floor would retroactively fail all 25 bands on a criterion
no ADR has ratified (smallest per-band class count is 120). Recorded for a
ruling with numbers instead.
[Verification]: uv sync --locked on canonical CPython 3.12.13; in-worktree
smoke 569 passed (556 baseline + 13), deductive 285 passed. Registered in the
`smoke` curated suite -- not left to `full`, which gates nothing. Mutation-
checked: doubling CASES_PER_BAND -> 2 failed; reporting committed as distinct
-> 4 failed; gating on `claimed` instead of `honest` -> 3 failed; tree restores
to 13 passed.
Phase A of the curriculum-license-loop arc. Design only; no production code,
no flag, no default changed.
Rules R1-R9: polarity is a row-level field (absent => affirmative), negatives
compile to the sentential-not form and MUST reuse the affirmative connective
(atom identity), contradiction is rejected at ratification, premise
compilation becomes query-scoped, an empty scope is UNKNOWN, premise_count
keeps reporting family size, the oracle learns polarity independently, and a
band's honest ceiling must be reported before anyone authors for it.
Three findings, each measured in-tree and each reversing something:
1. `polarity` is read by nothing. A row authored to refute a question today
serves a confident wrong "Yes" -- and the independent oracle ignores the
field for the same reason, so gold agrees and wrong=0 stays green. This is
the silent-failure class Phase A existed to prevent, now demonstrated.
2. The 16-premise honesty cap holds a family to <=16 chains; at 17 the band
declines everything, including the taught positive that works today. So
ADR-0262 §5.1's own remedy (author ~219 relations) destroys the capability
at row 17, tripping the fix §6 deferred as a future contingency. Jointly:
a band has <=16 entailed cases against a 657-committed threshold, so no
curriculum band can earn SERVE until scoping lands. The blocker is
engineering, not content -- inverting the conclusion two arcs closed on.
3. Honest volume is bounded by taught vocabulary, not corpus size. 8 of 11
bands cannot reach 657 at all, including the plan's chosen first target
physics·modal (ceiling 480, counting every possible question). Retargets
Phase F to philosophy_theology·modal (ceiling 44,104, same 8-chain start).
R5 is the only rule that could change an existing answer, so it is the only
one carrying evidence: 8,520 routable questions, 0 verdict mismatches for both
candidate scopes. Verdict-identity holds for any scope that is a superset of
the query-atom rows, since each premise mints one independent atom. That is
stronger than ADR-0262 §6's soundness argument, and it is why this narrowing
is not the ADR-0261 §5.1 premise-dropping failure.
ADR-0262 §5.1/§5.2/§6 carry forward-pointers; original text preserved.
[Verification]: uv sync --locked on canonical CPython 3.12.13; in-worktree
`core test --suite smoke -q` 556 passed (555 baseline + 1: the derived
ratify-on-merge pin picked up ADR-0264 and discharged it), `--suite
deductive -q` 285 passed. Four probes reproducible from
docs/research/curriculum-premise-scope-2026-07-25.md; the corpus-mutating one
restores the file and asserts byte-identity.
Nine ADRs (0254, 0256-0263) were merged into main and left stamped Proposed.
Two carried an explicit ratify-on-merge predicate their own merge had already
discharged, and ADR-0256 governs deduction_serving_enabled, which was ratified
True on 2026-07-24 and is serving live traffic. So the governance record
asserted "not yet decided" about a decision already in force.
That is the asymmetry the assessment arc (#113) found one file over in
workbench/api.py: the honest path degrades, the stale record lies. An unwritten
ADR is a visible gap; a Proposed one that is actually in force is a false
statement.
Each stamp records the ACTUAL ratifying act -- "Accepted, ratified by Joshua
Shay via <merge> (<sha>, <date>)" -- derived from the commit that added the file
and verified an ancestor of main, not assumed. Merge authority is Shay's alone
(AGENTS.md: no merge automation), so the merge IS the ratifying act.
No ADR content changed. No flag changed. ADR-0262's stamp says so explicitly:
accepting it does NOT enable curriculum_serving_enabled, which stays False
pending ratified volume -- eleven bands re-measured today, still 24x-73x short.
tests/test_adr_status_governance.py pins two independent invariants in the
smoke (pre-push) suite:
1. A default-ON flag is not governed by a Proposed ADR. The flag -> ADR mapping
is DERIVED by walking core/config.py for `<name>: bool = True` and reading
ADR refs from the preceding comment block -- not a hand-written table, which
would be the same second-copy-of-a-closed-set defect ADR-0256's arc fixed.
2. A ratify-on-merge predicate cannot coexist with Proposed. Self-discharging:
the file being on main IS the merge having happened.
Plus a vacuity guard, because a derivation that parses zero flags would make
every other assertion pass on an empty set.
Registered two orphans found in passing: test_adr_index.py (5) and
test_ratification_ceremony.py (14) landed in #113 in NO curated suite, so 19
tests -- including the one mechanism that can move curriculum volume -- ran
only under `full`, which gates nothing. Fifth instance of this shape.
Deliberately NOT fixed, recorded in the research doc: the 312-file corpus has
27 unparseable status lines and draft/ratified/active variants. A closed-vocab
assertion would fail on ~35 pre-existing files and get muted, and a muted gate
reads as coverage.
[Verification]: smoke 555 passed in 137.73s (236 baseline + 314 + 5, +1.2s);
governance pin 314 passed in 1.18s standalone and MUTATION-CHECKED -- reverting
ADR-0256 to Proposed fails both invariants independently (2 failed/312 passed);
orphans 19 passed; ruff clean. Canonical Python 3.12.13, uv sync --locked.
The full 99-register run is green: 801 passed, 0 failed, up from 99 failures on
clean main. bf17f42's "DO NOT MERGE until green" is hereby satisfied; the fix in
bf17f42 + bec76d4 is verified.
Records the whole thing, including what was NOT broken: the load-bearing
ADR-0072 claim (test_register_matrix_trace_hash_invariant) passed throughout, on
main and after. trace_hash folds hash_surface, so a real truth-path leak would
have moved it, and it never did. The invariant was intact the entire time — it
just was not observable, because hash_surface was pipeline-local, which is why
the test drifted onto `surface` when Phase 0 changed what that field means.
Also records the wrong turn: the first patch aimed at
evals/cognition/runner.py::CaseResult, while the test consumes
evals/metrics.py::CaseResult via run_cognition_eval. Thirteen files here define
a class called CaseResult. Follow the import, not the name.
[Verification]: register matrix 801 passed / 0 failed (17m50s), including the
trace_hash invariant across all 99 registers; capability index + eval harness 23
passed. evals/metrics.py::CaseResult gained a DEFAULTED field and its only other
consumers (calibration/tune.py, calibration/replay.py) never construct it.
NON-CANONICAL: Python 3.12.11.

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.

Re-checks every load-bearing claim of an external architectural assessment
(18 observations + a five-pillar blueprint) against the tree, by reading the
implicated code and, where possible, executing it.
Headline: Workbench records a proved deduction answer as ungrounded. With
deduction_serving_enabled ratified ON, chat/runtime.py stamps
TurnEvent.grounding_source="deduction", and workbench/api.py's
_coerce_grounding_source whitelist silently rewrites it to "none". Verified by
running workbench.api._run_chat_turn, not by reading. Scope is one field:
epistemic_state still reads epistemic_state_needed (honest) because
workbench/api.py:818 prefers the TurnEvent's own value. The unregistered path
degrades honestly; the hand-copied whitelist asserts a falsehood.
Falsified items, with evidence:
- parents[n] audit — run: 168 sites, 0 outside the repo root.
- realizer-guard exemption — documented at both guard sites.
- T12 — present in the weekly-audit stragglers TODO.
- assert_corpus_sound — already domain-parameterized and called unconditionally.
- promotion oracle — already the wrong=0 lane gate, per tier-s-housekeeping §3.
- accrue_realized_knowledge — a session-memory deployment profile, not a debt clock.
- cross-subject proof — resolve_domain fails closed on ambiguity.
Also corrects the blueprint's flagship item: EntailmentTrace carries BDD node
keys, not derivation steps, so multi-step articulation is engine work
(proof-term extraction), not a rendering-layer gap. And records that the
"second subject arena" premise is falsified by the curriculum-volume
measurement — 11 bands across 4 subjects already route, all 24x-73x short.
Companion Apple Silicon/MLX blueprint assessed: both premises contradicted by
the repo's own benchmark report (no MLX in any runtime path; Rust backend
opt-in and off). One of five items adopted (typestate), one rejected on
numerics (bf16 against a 1e-6 gate).
[Verification]: docs-only change; no code paths touched. Findings themselves
were executed against a scratch venv — the repo pins ==3.12.13, which uv
cannot fetch for linux-x86_64, so the pin was left untouched.

- Promote tests/test_register_substantive_consumption.py into the smoke
suite (local core/cli_test.py + mirrored .github/workflows/smoke.yml):
the falsifiable register-axis (ADR-0069/0071/0077) contract was red on
main outside every gate for the 2026-07-22..24 window, masked by an
unrelated flake label. 36 tests, ~4.6s.
- Found in passing: test_core_test_deductive_suite_expands_to_entailment_lane
was already red on clean main (an exact-tuple pin from when the
`deductive` suite had one file; it has since grown to 12). Fixed to a
contains-style assertion so it can't go stale the same way again.
- Two new capability-index adapters: deduction_serve_existential_result
(Band v6-EX alone — the one band among six that changes the decision
procedure itself) and curriculum_serve_result. Breadth 11 -> 13; baseline
re-frozen (a deliberate re-freeze per its own docstring).
- Promotion sweep: confirmed via the existing wrong=0 lane gate (run
repeatedly this session across 166/166 deduction-serve cases) that no
split beyond the already-applied ds-mem-0020 has a stale declined-gold
case a current band now decides differently.
`core proposal-queue {status,list,show,review}`: a read + review-state-only
CLI over the two proposal sinks that had a Python API but no operator
surface — teaching/proposals/comprehension_failures/ (N5 contemplation)
and teaching/proposals/derived_close_facts/ (idle_tick PR-2 bridge).
"review" appends to a sidecar log (teaching/proposals/review_log.jsonl)
recording that a human looked at an artifact; it never mutates the
artifact, never ratifies, never mounts, never flips a flag. The existing
ratification corridor (teaching/proposals.py, `core teaching
proposals`/`review`, a different sink) is untouched.
Found and fixed a real bug while building the second sink's reader:
generate/determine/derived_close_proposals.py's DEFAULT_SINK used
parents[3] instead of parents[2], resolving one directory ABOVE the repo
instead of inside it. Silent because the feature is default-off and no
test asserted the path — confirmed live via a stray artifact sitting
outside the repository since 2026-06-16. Pinned by
test_derived_close_default_sink_resolves_inside_the_repo.
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.
Implements the measurable test from COMPREHENSION-READER-AUDIT.md's Q5,
generalized to the deduction and curriculum composers: a deterministic
refusal histogram split mechanism/coverage/engine_refused, plus an
admissions-per-batch counter for measuring a future lexicon or curriculum
expansion's effect as a before/after delta instead of asserting it.
Found and fixed a real classification bug while building it: an argument
successfully read by a band but declined by the ROBDD engine for
inconsistent premises was being misattributed to whichever reader band
happened to run last in the fallback cascade. That case is neither a
shape gap (mechanism) nor a vocabulary gap (coverage), so it gets its own
"engine_refused" bucket rather than being folded into either.
Baseline measurement: deduction refusals are 100% mechanism-class today
(the bands read a closed connective grammar, not open vocabulary) —
curriculum refusals are a real mechanism/coverage mix, confirming the
volume ceiling S6 quantifies independently from the ratified-chain side.
Re-measured the frozen holdout_dev/v1 500: correct=5 wrong=0 refused=495 —
exactly the tune-3 + measure-2 increment 1 recorded, no drift, wrong=0 held.
Seeding-sentence injection is already in the tree (NEUTRAL_COUNT_VERBS in
math_roundtrip.py, consumed by the seed matcher and the comparison anchor);
its measured yield when it shipped was 0 conversions, verified four ways.
Extending the allowlist further is the move ADR-0251 and the overfit
inventory forbid — per-case pattern growth previously produced lift that
committed WRONG answers on the real exam.
Recommendation: mark Phase 4.1 complete-with-null-yield and re-point Phase 4
at the reader arc's own live recommendation — increment-2 CASE-FIRST on the
already-identified closest cases (0000/0001/0148/0082).
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.
Pins the arc's original goal against the ACTUAL serving spine (ChatRuntime,
the driver core chat constructs), not just the composer: a user asks a basic
logic question -> CORE decides -> an articulated, deterministic, telemetered
response comes back. Covers propositional + categorical, flag-off byte-identity
across both bands, honest reader-refusal on out-of-regime input (INV-34), and
the peripheral-systems wiring.
Peripheral systems verified (nothing to build, all automatic): deduction
turns are well-formed served turns (turn_log grows, _context.turn advances)
so ADR-0255 discovery-yield counts them; they carry grounding_source=
'deduction' on ChatResponse + TurnEvent and an observable DispatchAttempt;
they emit no discovery candidates (decided answer, not a would-have-grounded
gap) so they lift the yield denominator without inflating the numerator.
Scope-out doc (docs/research/deduction-serve-arc-completion-and-scope-outs-
2026-07-23.md) records the whole arc + everything deliberately deferred with
rationale: multi-word English reader relaxation (risky, shared reader, its
own pass), multi-step proof recap (Phase-6 core_logos), accrue_realized_
knowledge default, ADR-0246 s3.7 (blocked on research evidence not wiring),
Tier-2 (waits for field reader), Hamiltonian compiler (eval-side), and the
GroundingSource enum registration.
New: tests/test_deduction_serve_e2e.py (5 tests through the real REPL path).
[Verification]: core test --suite deductive 50 passed; smoke 180 passed;
cognition 122 passed/1 skipped.
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.
Deduction serving stops being a bare flag and becomes an EARNED capability
governed by the ADR-0175 reliability gate over the ADR-0199 learning arena
-- the arena's second concrete instance (GSM8K math is the first) and the
reliability substrate's first non-estimation serving consumer, a concrete
dent in that zone's standing 'designed, not wired' critique.
Non-circular thesis: the ROBDD engine is sound+complete (never wrong on the
problem it's handed), so the license does NOT certify it. It certifies the
full pipeline (reader -> projector -> engine) per argument shape -- the
FALLIBLE part is the template reader, which can misparse an argument and
hand the engine the wrong problem. The arena catches that as a 'wrong' by
comparing the pipeline's committed outcome to by-construction gold.
New: generate/proof_chain/shape.py (4 exhaustive structural shape-bands, the
capability axis, shared by arena + serving), evals/deduction_serve/practice/
(the deduction arena instance: deterministic synthetic corpus, by-construction
gold independent of the reader per ADR-0199 L-2, cross-checked against the
INDEPENDENT truth-table oracle before sealing), chat/data/deduction_serve_
ledger.json (committed SHA-sealed ledger, 4 bands x 720 correct/0 wrong),
chat/deduction_serve_license.py (tamper-evident serving reader, mirrors
estimation_license.py), tests/test_deduction_serve_license.py (13 tests),
docs/adr/ADR-0256 (+ resolves the ADR-0206 numbering collision in doc form).
Changed: chat/deduction_surface.py (composer consults the license: earned
band -> authoritative Phase-1 surface; unearned/stripped ledger -> same sound
answer served DISCLOSED/hedged -- authority now rests on committed evidence,
not a boolean), core/config.py (flag docstring: enables an EARNED path),
core/cli_test.py (deductive suite runs the license test).
All four structural bands earn SERVE at reliability 0.99087 (>= theta_SERVE
0.99) with wrong=0, so Phase-1 behavior is preserved byte-for-byte; the
gate's teeth are proven by injecting an empty ledger (the same sound answer
degrades to a disclosed hedge). Did NOT reuse the ADR-0206 govern_response
bridge (its STRICT/APPROXIMATE 'widen-past-strict' semantics are the opposite
shape from deduction's always-sound answer); did NOT rewrite report.json's
stale adr field (SHA-pinned bytes, documented in ADR-0256 s2a instead).
[Verification]: smoke 180 passed; cognition 122 passed/1 skipped;
core test --suite deductive 38 passed; architectural_invariants 75 passed;
practice runner 4 bands all SERVE wrong=0.
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.

Wires the verified ROBDD entailment engine (generate/proof_chain,
716/716 wrong=0) into core chat serving. A propositional argument
('P1. P2. ... Therefore C.') is now comprehended, projected, and
decided end-to-end -- the first real working basic-logic workflow:
user question -> CORE decides -> articulated deterministic answer.
New: chat/deduction_surface.py (DEDUCTION composer, sibling to the
existing oov/narrative/example composer pattern), generate/proof_chain/
render.py (deterministic EntailmentTrace -> surface templates, no LLM),
tests/test_deduction_surface.py (15 tests incl. full propositional gold
corpus decided end-to-end across a multi-turn session, wrong=0).
Changed: core/config.py (deduction_serving_enabled flag, default off),
generate/intent.py (IntentTag.DEDUCTION, observability-only -- the core
classify_intent rule table is untouched so flag-off stays byte-identical),
chat/runtime.py (one flag-gated block in the existing pack/teaching/
partial/oov dispatcher).
Design notes (full detail in docs/research/deduction-serve-arc-phase1-
turn-spine-2026-07-23.md): the deduction check runs BEFORE generic intent
classification (never touches classify_intent's rule table) and BEFORE
the empty-vault gate (a live multi-turn probe caught turn-12 silently
falling through once the vault warmed -- pack/teaching/oov are cold-start-
only by design, deduction serving isn't). grounding_source='deduction' is
NOT registered in the closed, Workbench-coupled GroundingSource Literal
(cross-stack TS contract, inert for this arc's core-chat-only consumer,
documented as a deferred follow-up). Band v1 stays propositional-only --
categorical/syllogism arguments commit but honestly decline as
out-of-band; evals.syllogism.oracle is never imported (INV-25 intact).

Pins the pre-arc baseline for the basic-logic end-to-end workflow
(user logic question -> comprehend -> decide -> articulate).
Central finding, proven with a runnable probe: every organ the workflow
needs already exists and is verified wrong=0, but none are wired to each
other on the serving path. comprehend()+to_deductive_logic/to_syllogism
decide 'If p then q. p. Therefore q.' -> entailed and a Barbara syllogism
-> valid=True in isolation, while ChatRuntime.chat() on the SAME text
returns a pack token-gloss surface (grounding_source='pack',
refusal_reason='') — the deductive engine is bypassed entirely.
Baseline (all wrong=0): 7 comprehension lanes green on curated gold;
deductive engine 716/716 (dev 200 / holdout 500 / external 16);
proofwriter-owa 9 correct / 10 refused / 0 coverage-gaps; smoke 180 passed.
Band v1 = propositional + syllogism projectors. Input boundary defined
precisely: single-token propositional atoms in 'P1. P2. Therefore C.'
form, and single-word-term categorical syllogisms (declarative AND
interrogative). Multi-word English propositions ('the ground is wet')
refuse via reader _RESERVED guard -> deferred to Phase 4 widening.

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).

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.
Mapper required only that total include {a,b}; rebuild-from-binding then
dropped third entities and could emit a certified wrong answer (e.g. 15
instead of 115). Require exact total part-set {a,b}, refuse any contain
outside reference a, and agree with original-graph classical solve before
emit. Adds multi-entity refuse unit tests.
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.
Trace every module/class the six retired paradigm documents introduced or
proposed, plus a general zero-importer sweep of generate/, core/, evals/.
Every candidate is one of: never built, already removed in a prior pass, or
live (imported by the serving reader / a protected dependency chain, and/or
test-covered). No code removed; no behavior change.

Records the reader-arc recalibration: halt bespoke-per-case regex work,
verified clean-base reset to main@854ce023, and eradication of
feat/reader-inc2-caseband's (PR #80) debt (loosened _token_in, empty
proof file, bundled provenance) without merging that branch.
Preserves the genuinely-general knowledge before the branch is retired:
the has_numeric_token multiplier-blindness bug (root cause + minimal fix
idea, deliberately not landed) and case 0148's correct-for-the-right-reason
decomposition, both independently re-verified against source rather than
copied from the branch's own claims (which included a stale narrative
about a graph-dump proof file that was actually committed empty).
Adds a file:line-cited overfit inventory (31 bespoke/single-case surface
patterns) as inventory only -- nothing removed, the existing regex reader
keeps serving unmodified.
ADR-0251 proposes (not builds) a geometric surface->canonical
normalization spike using existing off-serving primitives
(conformal_procrustes, VocabManifold, the cognition pipeline's Phase C
anti-unification telemetry), wrong=0-gated against holdout_dev/v1, with
Smith-chart algebra and any Fibonacci "dimensional cascade" explicitly
disclaimed. Awaiting ruling -- no implementation started.
Records the increment-1 outcome straight (band-solve=0, ~30-band bet
falsified; foundations = banked byproduct not success) + the minimal-band
measurement: no small band converts; taxonomy not at bedrock (GSM8K statements
are per-sentence multi-capability); multi-compound highest-leverage (70/106
tractable needed-sets) but insufficient alone; q:complex biggest intractable
wall (~35 cases). Increment-2 recommendation = CASE-FIRST (target specific
closest cases, build their exact end-to-end needs) not capability-first, since
the taxonomy fragments. Foundations verified full-500 wrong=0, smoke 176.
The two reusable foundations of increment 1, both verified wrong=0:
- NEUTRAL_COUNT_VERBS (math_roundtrip): the shared positive-polarity ALLOWLIST
(production/acquisition/possession-count verbs), fail-closed. Extends ADD_VERBS
with curated neutral production verbs (score/write/teach/plant/harvest/produce/
draw/sing). Depletion/transfer (SUBTRACT/TRANSFER_VERBS) excluded by positive
determination — 'Alice lost twice as many' refuses, not via a blocklist.
- Seed reader: discrete_count matcher acquisition path aligned to the allowlist
(made/baked/grew/scored/wrote/taught now inject; depletion refuses).
- Comparison reader: _comparison_anchor_verb() allowlist extended to the same
NEUTRAL_COUNT_VERBS (keeps fail-closed; captures scored/caught/wrote frames).
Verified: production injects, depletion refuses; 71 pinned comparative tests
pass (polarity guards now via allowlist); tune wrong=0; smoke 176 green.
FINDING (measured 4 ways: yield harness, band map, band oracle, capability
histogram): band-1 as scoped {seed + forward-comparison + q:simple/summation}
converts 0 tune cases. Its otherwise-in-band cases STRAND on multi-compound (25)
and compare-additive (17) — capabilities outside the ~30 band. The conjunction
recurs at sub-capability granularity; the band-map taxonomy was too coarse.
Foundations validated + reuse-ready (done-when part 2); band-solve>0 (part 1)
needs the band to grow to +compare-additive(+multi-compound) — a scope/done-when
ruling for Josh. No merge until ruled.
Design-first plan, ruling before any build (same gate as #76). Band =
foundational spine core: seed-simple + comparison + question-arithmetic
(simple/summation/difference), on the shared #78 polarity substrate.
Bakes in Josh's four refinements: (1) deliberate ~30 smaller-band rationale
(first end-to-end reader conversion ever + two reusable foundations, zero new
hard capabilities beyond #78); (2) done-when reset to band-solve>0 wrong=0 +
foundations validated, ~40 bar cumulative across increments 1-3; (3) haircut
factor (real/upper-bound) as a named output; (4) TWO wrong=0 direction drivers
— #78 statement polarity AND q:difference question direction, both positively
determined + fail-closed. Grounds design on what EXISTS (question layer partly
built: summation works, q:difference partial). Schedules q:complex decomposition
next (may be corridor-tractable, could move the ~48% ceiling).
Reverts the c3aed13b parser change (frame-anchored comparative regexes +
verb-free connector + _COMPARE_POLARITY_BLOCK + 'as much'); the reader stays
on the _comparison_anchor_verb() whitelist (fail-closed). Increment 1 ships
the compiler tier + the funnel finding only.
Three reasons on record: (1) frame-anchoring converts 0 of 500 official cases
— zero measured benefit today; (2) its consumer is rate-frame admission, a
later increment — the next increment (seeding-sentence injection) is a shared
layer that doesn't touch it; (3) the polarity blocklist is fail-OPEN — an
unenumerated depletion verb in a complete frame is a coherent-but-inverted
graph = a wrong on the run-once sealed arbiter (round-trip guards parse
consistency, not gold-correctness), a trade the fail-closed doctrine never
takes for zero gain.
Verified before revert-merge: with the whitelist reader, the 5 real compare
parses are non-divergent — test_real_compare_cases_solved_wrong_zero still
sees 5, solves 5, wrong 0 (corridor real-reach 0->5/500 preserved).
Frame-anchoring recorded as an OPEN DESIGN TASK owned by the rate-frame
increment: frame + POSITIVE polarity determination (neutral-polarity allowlist
or small polarity classifier), not assume-safe-unless-blocklisted. Detail in
docs/research/compare-increment-funnel-2026-07-18.md.
Increment 1 reader half. Re-anchor the two multiplicative-comparison frame
regexes on the closed-class frame ('<factor> as many/much <unit> as <REF>')
instead of the _comparison_anchor_verb() whitelist: the verb slot becomes a
verb-free bounded connector, 'as much' joins 'as many'. Admission is now
open-class for safe verbs (scored/wrote/caught/taught/…), gated by the frame.
One closed class is NOT frame-neutral — polarity-inverting/depletion verbs
(lose/spend/give/sell/win/donate/pay/eat/drop/lend): in a compare frame they
make the compared quantity a loss, so actor=factor×reference reads backwards
→ wrong>0. _COMPARE_POLARITY_BLOCK excludes exactly that set (the sanctioned
fallback; the frame is the gate for every other verb). Pins the wrong=0
guards in test_adr_0131_G2a + test_recognizer_comparative_inject.
Develop-on-tune / measure-once held. Footprint over 500 official cases: tune
byte-identical (0 divergences, wrong=0, PARSED=3); measure 1 divergence
(0441 'Zig wrote four times as many books as Flo') which advances
frame-refusal -> question-refusal (sanctioned delta) but does not solve — the
binding wall is the shared summation-question layer. X=15 measured delta=0.
Ruling per the funnel-conditioned escalation rule: mass is in shared layers,
so the next increment is shared-layer (summation-question reader), not a
practice escalation and not more compare frames. wrong=0 held on tune (261),
measure (239), smoke (176).
