After RAT-1's architecture audit exposed five systematically
underbuilt components, A (the 4 missing injectors) is being taken by
this agent. The other four are parallel-safe and each gets its own
dispatch brief:
B (Opus) — contemplation produces ratifiable claims (medium)
C (Sonnet) — comprehension reader audit + decision (small→medium)
D (Sonnet) — core teaching coverage CLI (small)
E (Codex) — lexical ratification auto-compile (tiny)
Each brief carries: operator profile, branch name, base, dispatch
line, reads required FIRST, outcome inventory, hard requirements,
tests, truth test. Anti-regression invariants enumerated. All
parallel-safe — no shared file conflicts.
The dispatch DAG names ALL FIVE pieces with A in-flight as a peer.
The user's question — "shouldn't we be running it multiple times so
it can learn? or is that part broken?" — exposed that the math
teaching loop's `ratify → admit` closure had been structurally
broken at the connector between operator ratification and runtime
visibility. The handlers wrote source files (compositions/, frames/)
that the runtime loader never read because no compile step
regenerated the runtime artifacts.
This PR fixes the gap end-to-end AND fires the first live composition
admission on the canonical pack.
Modules
-------
- language_packs/compile_pack.py — unified compile step that
regenerates frames.jsonl + compositions.jsonl + updates
manifest.{frame,composition}_checksum atomically. Idempotent.
- teaching/math_composition_ratification.py — apply_composition_claim
now calls compile_pack at end of successful ratification. Closes
the source-file→runtime-artifact gap.
- teaching/math_frame_ratification.py — same auto-compile wire for
apply_frame_claim.
- generate/math_candidate_parser.py — CandidateInitial gains optional
composition_evidence Mapping field. When populated, signals the
candidate was produced by a registry-gated composition (ADR-0169);
the value/unit/entity are DERIVED arithmetic over grounded inputs.
- generate/math_candidate_graph.py — new _composed_initial_admissible
predicate that branches on composition_evidence. Wrong=0 preserved
by requiring each composition INPUT token (count, amount) to ground
in source_span literally; the derived value is admitted because the
arithmetic over grounded inputs is deterministic.
- generate/math_candidate_graph.py — discourse-level prior_subject
tracking: capture proper-noun subjects from ALL statement sentences
(including ADR-0136.S.0 context-filler sentences that get filtered
out before the candidate loop). Without this, "John adopts a dog"
(no numbers) is dropped and the cross-sentence subject resolver for
case 0019 sees prior_subject=None.
- generate/recognizer_match.py — all four composition matchers
(ME-1 currency-per-unit same-sentence, ME-2 cross-sentence, ME-3
additive, ME-4 subtractive) now populate composition_evidence in
CandidateInitial. Also added standalone " each " / " apiece " to
_PER_UNIT_TOKENS so currency_amount detection-only matcher refuses
per-item costs instead of swallowing them.
CLIs
----
- core teaching compile-pack — explicit operator surface for
regenerating runtime artifacts. JSON output for CI integration.
- core teaching seed-recognizer — operator surface for seeding a
RatifiedRecognizer entry in the proposal log for a given
(shape_category, anchor_kind). Writes created + transition(accepted)
events directly via ProposalLog._append.
Seeded artifacts (the actual loop closure)
------------------------------------------
- proposals.jsonl: new rat1-seed-48dd2673d6ad673d RatifiedRecognizer
entry for shape_category=rate_with_currency,
anchor_kind=currency_per_unit_composition.
- compositions/multiplicative_composition.jsonl: ratified
"bound(count) × bound(unit_cost)" affirms entry sourced from
case 0019 evidence.
- compositions.jsonl + manifest.composition_checksum: compiled
runtime artifact + manifest pin (RAT-1 auto-compile).
Live result on train_sample
---------------------------
- wrong == 0 preserved (3 correct / 47 refused / 0 wrong)
- Case 0050 hazard pin holds (refused)
- public split 150/150 preserved
- Case 0019 sentence 1 ("requires 3 vet appointments, which cost
$400 each") NOW ADMITS via composition. Previously refused with
"recognizer matched but produced no injection". The refusal moved
downstream to sentence 2 (a different currency_amount detection
bottleneck that is its own follow-up).
This is the first time a composition ratification on the canonical
pack actually reaches the runtime. The flywheel turned one
revolution.
Tests
-----
- tests/test_rat1_end_to_end_admission.py — 4 new live tests:
composition statement admits on isolated synthetic problem, case
0019 cross-sentence admission, wrong=0 preserved on train_sample,
case 0050 hazard pin.
- tests/test_consumption_empty_registry_no_op.py — refactored to use
isolated synthetic packs (the canonical pack may now carry ratified
entries).
- tests/test_math_{frame,composition}_ratification.py — updated
"manifest checksum unchanged" tests to "lexicon checksum
preserved" semantics: RAT-1 auto-compile may add the new optional
checksum fields; pre-existing lexicon checksum stays untouched.
Suite results: teaching 93, packs 131 (+4), runtime 20. All green.
Final PR of the matcher-extension wave. Ships:
1. tests/test_me5_all_categories_integration.py — 4 new tests:

- test_all_safe_categories_have_extension_admission: pins that
SAFE_COMPOSITION_CATEGORIES is exactly the three covered

polarity discipline holds across all three matchers

Extends _match_multiplicative_aggregation with a new branch keyed on
anchor_kind="additive_quantity_composition". When a statement carries
"<Subject> <verb> <N> <unit> and <M> <unit>" (same unit) shape, emits
a pre-composed CandidateInitial(N+M, unit) and publishes
composition_shape="bound(qty_a) + bound(qty_b)".
Subject binding under Option A (refuse on pronoun / determiner / no
proper-noun head). Cross-sentence subject support (mirroring ME-2)
is deferred — not needed for the v1 ME-3 canaries.
Verb whitelist: lost / gained / earned / saved / made / paid / spent /
bought / sold / added / removed / received. Verbs that route through
CandidateInitial.matched_anchor's existing post-init whitelist;
unmapped verbs fall back to "had".
Unit normalization: rstrip 's' for plural matching (pounds vs pound).
Cross-unit composition refused — no conversion table in v1.

Without those, the wiring is correctly positioned but dormant — no

Modules

prior_subject) — refuses on None / empty / pronoun prior_subject;
publishes the same composition_shape + composed_initial payload as

- extract_proper_noun_subject(statement) — head proper-noun extractor
used by callers to track running prior_subject; rejects determiners,
sentence-initial connectors (After/How/Every/...), and pronouns
- match() dispatcher gains keyword-only prior_subject parameter;
when a per-category matcher returns None for a RATE_WITH_CURRENCY

Scope boundary
--------------
The wiring is load-bearing AND tested end-to-end via synthetic
recognizer registry (test_case_0019_admits_with_prior_subject_john
proves the full chain match → inject → admit).
For the LIVE train_sample case 0019 admission, two ratifications must
also be seeded (operator workflow outside this PR's code scope):
1. A RatifiedRecognizer in the proposal log with shape_category=
RATE_WITH_CURRENCY and canonical_pattern carrying
anchor_kind="currency_per_unit_composition"
2. A composition_registry entry for "bound(count) × bound(unit_cost)"
under multiplicative_composition with polarity=affirms
With both ratifications in place, case 0019 admits via the wiring
this PR ships. Without them, the live train_sample run remains at
the 3/47 baseline (preserved; no regression).
Anti-regression invariants preserved
------------------------------------
- wrong == 0 on gsm8k_math public
- Case 0050 hazard pin holds (no _COMPOSITION_SUBJECT_BUY_RE or
_CROSS_SENTENCE_COMPOSITION_RE match on case 0050's sentences)

Stacks on PR #400 (base: feat/matcher-extension-currency-per-unit-composition).
Two pre-public-release refreshes:
1. docs/position_paper.md §4 — refresh refusal taxonomy
The previous table listed an older taxonomy (fraction_operand /
compound_comparative / etc.) that does not match the current
candidate-graph eval output. Replaced with the actual taxonomy
emitted by the train_sample runner — refusals are categorized by
shape (recognized_but_uninjectable + per-ShapeCategory) which ties
directly to the architecture's recognizer/injector concepts.
Also refreshed §5 "Honest Gaps" to describe the active frontier in
terms of injector coverage (the registry-driven composition path)
rather than parser-level grammar extensions. The 47/50 refusal
count, 3/50 correct count, and wrong=0 invariant are unchanged.
2. COMMERCIAL_LICENSE.md — enumerate subsystems explicitly
The previous "vault memory / versor engine / epistemic teaching
loop / ingest / admissibility gate / holonomy encoder" listing
predated the math-domain composition wave. Expanded the list to
cover the full current architecture:
- versor engine + Cl(4,1) algebra
- vault + exact CGA recall
- ingest gate
- admissibility gate + Forward Semantic Control
- holonomy encoder
- epistemic teaching loop (ADR-0055..0057)
- contemplation loop + decomposer (ADR-0080, ADR-0172)
- math-domain ratification handlers (ADR-0167..0169)
- composition-pattern registry + registry-driven injector
- audit-as-teaching-evidence corridor
- identity + safety pack subsystems
- language-pack compiler + verified manifest checksums
- Logos articulation + three-language vocabulary manifold
- Rust algebra backend
- any derived or successor implementation
Explicit "enumerated subsystems are illustrative, not limiting"
clause covers any future module + ADR-ratified contract under the
same terms. New subsystems are covered automatically.
LICENSE (the non-commercial form) is unchanged — it already covers
"Software" broadly. CLAIMS.md is auto-generated and was verified
current (regeneration produces no diff).
Follow-up to PR #398 — lights up the dormant consumption path by
extending _match_rate_with_currency to publish composition_shape +
pre-composed CandidateInitial in parsed_anchors.
Scope: one matcher extension (_match_rate_with_currency) for the
currency-per-unit composition shape ("$X each"). Other composition
shapes (multi-quantity, additive, subtractive) deferred to ME-3/4/5
follow-ups.
Subject binding decision pinned: Option A (refuse when same-sentence
subject is absent). Forbids Option B (placeholder subject —
fabricates attribution). Defers Option C (cross-sentence subject)
to its own ME-2 brief.
Honest consequence: case 0019 stays refused in THIS PR (requires
Option C). Truth-test #1 replaced with a synthetic "Maria bought 3
vet appointments at $400 each" canary that has same-sentence
subject. The flywheel turns one revolution: ratify → compile →
load → consume → admit, end-to-end on the synthetic canary.
Operator profile: Opus (load-bearing wrong=0; pre-composed
CandidateInitial; case 0050 mandatory pin).
Test surface enumerated (4 test files, 12+ tests):
- test_matcher_extension_currency_per_unit (8 narrowness tests)
- test_matcher_extension_case_0050_hazard_pin (mandatory)
- test_matcher_extension_end_to_end_admission (truth test)
- test_matcher_extension_train_sample_baseline_preserved
- test_matcher_extension_public_split_preserved
6-row truth test pinned. Anti-regression invariants enumerated.
Forbidden surface includes Option B + new SAFE category entries +
solver mutation.
Recommended next dispatch sequence: ME-1 → ME-2 (case 0019) →
ME-3/4/5 (remaining composition shapes).
Closes the consumption-half of the math teaching loop for two of three
sub-types per docs/handoff/CONSUMPTION-WIRING-DISPATCH-PACK.md (PR #397).

- language_packs/compiler.py — manifest verification extended for
frame_checksum + composition_checksum, mirroring the proven

Scope Boundary (honest finding)
-------------------------------
Rows #1 and #3 (case 0019 admission) require a matcher extension that
publishes ``composition_shape`` + a pre-composed CandidateInitial in
parsed_anchors. The existing currency_amount / multiplicative_aggregation
matchers in generate/recognizer_match.py are detection-only (return
empty parsed_anchors). This PR ships the consumption infrastructure
correctly but the runtime path remains dormant until a follow-up PR
extends the matcher. The dispatch pack's truth test #1/#3 cannot fire
without that extension.
The wiring is positioned correctly: inject_from_match → consult
composition_registry → admit on affirms-with-payload, suppress on
falsifies, refuse on absence. A synthetic recognizer match with
populated composition_shape + composed_initial DOES admit through the
new path (covered by 6 tests in test_composition_consult_in_injector.py).
A follow-up brief naming the matcher-extension work is the
recommended next step.
Anti-regression invariants verified
-----------------------------------
- wrong == 0 on core eval gsm8k_math (public 150/150)

- ADR-0167 partition — no cognition imports in any new module

- SAFE_COMPOSITION_CATEGORIES enforced at write AND load

Production-line dispatch form of the consumption-wiring brief in
PR #396. One bundled PR recommended (CW-1 + CW-2 share pack-compile
+ manifest extension + case 0050 pin). Split only if CI cycle time
forces.
CW-1 — Frame consumption:
language_packs/compile_frames.py + generate/comprehension/frame_registry.py
+ reader wire + manifest frame_checksum extension.
CW-2 — Composition consumption:
language_packs/compile_compositions.py +
generate/comprehension/composition_registry.py + injector wire in
generate/recognizer_anchor_inject.py + manifest
composition_checksum extension. SAFE_COMPOSITION_CATEGORIES
enforced at load (defense in depth); polarity "falsifies"
suppresses injection (not silently "affirms").
Truth test pinned as binding (6-row table). PR is not done unless
case 0019 admits, case 0050 stays refused, train_sample moves from
3/47 → ≥4/46, wrong==0 holds, public split unchanged (150/150),
empty-registry runtime byte-identical to today.
Operator profile: Opus (load-bearing wrong=0 surface; case 0050
mandatory pin; same rigor as CC-2).
Names the structural gap discovered in the first end-to-end
CompositionClaim ratification (2026-05-27 post-#393):
ratification handler writes JSONL artifacts cleanly, but no runtime
code reads compositions/*.jsonl or frames/*.jsonl. Two of three
sub-types ship the ratification half of the loop without the
consumption half.
State:
lexicon/ writer ✓ reader ✓ (LexicalClaim — closed)
frames/ writer ✓ reader ✗ (FrameClaim — half-open)
compositions/ writer ✓ reader ✗ (CompositionClaim — half-open)
Proposes one bundled PR (CW-1 + CW-2) mirroring the proven
generate/comprehension/lexicon.py::load_lexicon pattern:
CW-1 — Frame consumption: pack-compile frames/*.jsonl into a
runtime-loadable artifact; new load_frame_registry()
loader; reader wire.
CW-2 — Composition consumption: pack-compile compositions/*.jsonl;
new load_composition_registry(); injector wire in
generate/recognizer_anchor_inject.py.
Hard requirements: SAFE_COMPOSITION_CATEGORIES allowlist enforced
at both write and load (defense in depth); polarity "falsifies"
honored; manifest checksum extended per CLAUDE.md "Semantic Pack
Discipline"; empty-registry runtime byte-identical to today.
Truth-test pinned: success is the EVAL DELTA, not the artifact
append. PR is "done" when case 0019 (the canary I ratified) admits
under train_sample, train_sample moves from 3 correct / 47 refused
to ≥4 correct / 46 refused, case 0050 stays refused, wrong==0 holds.
This brief is orthogonal to the workbench UI wave (W1..W4); both
can ship in parallel. Recommended operator: Opus (load-bearing
wrong=0 surface; same rigor as CC-2).
W0 of the workbench-UI wave per WORKBENCH-UI-WAVE-SCOPING.md.
Pure docs PR; no UI code.
Decision: the workbench is a local keyboard accelerator for the
existing local-CLI ratification surface (ADR-0161 Surface C), not a
fourth ratification surface and not a new trust boundary. Every
workbench-driven ratification action invokes the same Python
entrypoint as the corresponding CLI invocation, with identical
preconditions, exceptions, and append-only JSONL effects.
Amends ADR-0160 v1 read-only stance narrowly: admits driving the
three Tier 1.5 handlers (apply_lexical_claim, apply_frame_claim,
apply_composition_claim) and the existing core teaching review path
through the workbench API. Honors ADR-0161's surface set unchanged
(workbench is part of Surface C, not a new surface). Honors ADR-0162
no-go list and pins the keyboard contract referenced in §7.
Five open questions from the scoping brief resolved:
Q1 in-process via existing Python entrypoints
Q2 single-operator (multi-operator deferred)
Q3 same chat/telemetry.py JSONL sink, new event kinds
(operator_ratify / operator_reject / operator_defer /
operator_navigate); no parallel log
Q4 fonts and icons bundled locally; no CDN
Q5 dist/ gitignored; CI verifies build, does not commit artifact
Ratification record extended with ratifier_kind: "workbench" — audit
forensic discriminant only, not a permission gate. proposal_id + to

no remote operator, no CORS relaxation, no new mutation paths, no
auto-ratify, no batch ratification, no engine_state writes outside
the existing checkpoint path, no parallel workbench-events log, no
mobile/responsive form factors (ratification stays on Surfaces A+B

has already settled (ADR-0160 stack pins + read-only trust boundary;
ADR-0162 design system + 15-component must-ship list + no-go list),
catalogs the current state (backend complete, frontend zero), surfaces
the five operator pain points sourced from the 2026-05-27 demo and the
CompositionClaim brief pack, and proposes a five-wave sequence:
W0 (docs) — Trust-boundary ratchet ADR (ADR-0173 working title)
admitting operator ratification through the workbench,
scoped to existing Tier 1.5 handlers (Lexical / Frame /
Composition) and pinning the keyboard contract.
W1 (base) — workbench-ui/ scaffold per ADR-0162 Branch 1.
W2 (read) — ProposalQueue + ProposalCard + ProposalDetailPanel.
W3 (act) — RatificationCommandPanel + handler dispatch (the
throughput multiplier).
W4 (verify)— TraceDrawer + ReplayTheater + EvalCenter.
Guardrails enumerated: CLAUDE.md docs discipline, ADR-0162 no-go list,
determinism, trust boundary, wrong==0, case 0050 hazard pin,
keyboard-first, accessibility, local-first, no engine_state writes
outside the checkpoint path.
Open questions (in-process vs out-of-process ratification, single- vs
multi-operator, telemetry path, font/icon bundling, build artifact
location) listed for W0 resolution. No code in this brief.
* docs(tier1.5+tier2): FrameClaim handler + Tier 2 W5 schema brief pack
Two parallel briefs ready for dispatch:
- F1: FrameClaim ratification handler (Opus) — implements ADR-0168 +
ADR-0168.1; turns 2 of 8 Tier 1 proposals into real GSM8K
admissions on ratify
- T2-W5: MathReaderInferenceProposal schema (Sonnet) — Tier 2 substrate
with two-arm test-and-learn type contract
Zero file overlap between briefs; safe to dispatch concurrently. W6+
deferred until FrameClaim is live (Arm 2 known-good preservation needs
a working handler to verify against).
* docs(briefs): correct pack + workbench paths in Tier 1.5/Tier 2 brief
Operator dispatching F1 (PR #389) discovered:
- Pack path is language_packs/data/en_core_math_v1/, not packs/en_core_math_v1/
- Workbench dispatch table lives in workbench/readers.py, not workbench/api.py
Both operators landed on the correct locations regardless. Folding the
corrections into #387 directly so future operators reading the brief
get the real paths.
Bundles three post-Tier-1 follow-ups into one PR (no scope change, no
new ADR — implementation tightening on the already-shipped corridor).
(1) Standalone JSONL self-containment
teaching/math_contemplation_proposal.py
+ to_jsonl_record() — emits proposal_id + full evidence_pointers
(nested dicts including audit_row) + full reasoning_trace.steps
+ from_jsonl_record() — inverse; goes through build_proposal()
so all invariants are re-validated; raises on proposal_id mismatch
canonical_bytes() UNCHANGED (still the content-hash function;
trace_id/proposal_id stability preserved)
core/cli.py W3 lane now writes to_jsonl_record() output instead of
canonical_bytes() — same compact-JSON encoding (sort_keys=True,
ensure_ascii=False, separators=(",", ":"))
workbench/readers.py loads via self-contained record fields directly;
decompose_audit() re-run removed. read_math_proposal() now reads
reasoning_trace.steps and evidence_pointers from the JSONL record.
(2) Widened change_kind heuristic dispatch
teaching/math_contemplation.py
+ _CHANGE_KIND_BY_PAIR table on (refusal_reason, missing_operator):

(unexpected_category, fraction_percentage_literal) → matcher_extension
(unexpected_category, descriptive_frame_question) → frame_reclassification

Single-key fallback (lexicon_entry/narrowness_violation/
frame_unrecognized) retained for completeness.
hypothesis-step justification text updated to reflect new table.
Result on audit_brief_11.json:
3 matcher_extension (was 0)
2 frame_reclassification (was 0)
3 injector_sub_shape (was 8)
0 vocabulary_addition (no unknown_word group ≥2 in train sample)
(3) shape_category structural gap
MathReaderRefusalEvidence does not carry shape_category, so the
proposal cannot derive it. All proposals continue to emit
ShapeCategory.UNCATEGORIZED with a structural-gap comment. No
invented values — handler dispatch decision (per ADR-0167-FOLLOWUPS
§1) drives ratification routing today, not shape_category.
Tests
+ W1: 5 new tests (to_jsonl_record self-containment, round-trip,
byte stability, proposal_id mismatch rejection, canonical_bytes
unchanged invariant)
+ W2: 3 new pair-dispatch tests + real-audit change_kind distribution
test + shape_category-uncategorized test
+ W3: 2 new tests (records are self-contained, round-trip via
from_jsonl_record); existing byte-comparison test updated to use
proposal_id ordering instead of canonical_bytes
+ W4: existing 6 tests updated to build JSONL via to_jsonl_record;
+ 1 new decoupling test that drops teaching.math_contemplation from
sys.modules and verifies the workbench still loads + serves detail
Verification
- core eval math-contemplation produces the expected 3/2/3 distribution
- core test --suite teaching -q → 33 passed
- core test --suite runtime -q → 20 passed
- All 57 ADR-0172 W1-W4 tests pass (49 existing + 8 new)
Determinism / invariants preserved
- canonical_bytes() byte-stable (test pins this)
- to_jsonl_record() byte-stable via sort_keys=True + no floats
- wrong=0 invariant: proposals stay evidence-only; no auto-apply
- ChangeKind Literal unchanged (4 values; no new ones invented)
Wires teaching/math_proposals/proposals.jsonl into the CORE Workbench
API (ADR-0160) alongside the existing cognition proposal queue:
workbench/schemas.py
- MathReasoningStep, MathProposalSummary, MathProposalDetail,
MathRatifyResult schemas
workbench/readers.py
- MATH_PROPOSALS_JSONL + _DEFAULT_MATH_AUDIT_PATH constants
- teaching/math_proposals added to ALLOWED_ARTIFACT_ROOTS
- _HANDLER_DISPATCH table (vocabulary_addition→LexicalClaim; all
others not yet implemented)
- list_math_proposals(), read_math_proposal(), ratify_math_proposal()
- read_math_proposal() re-runs decompose_audit() to recover full
4-step reasoning trace (canonical_bytes only carries trace_id)
- ratify_math_proposal() raises NotImplementedError with clear
"handler not yet implemented: {change_kind}" for unhandled kinds
workbench/api.py
- GET /math-proposals, GET /math-proposals/{id}
- POST /math-proposals/{id}/ratify → _math_ratify()
(vocabulary_addition→200/routed; unhandled→501 with loud message)
tests/test_adr_0172_w4_workbench_e2e.py — 6 tests:
1. loads from JSONL
2. renders domain:math badge (distinct from cognition /proposals)
3. ratify-vocabulary_addition routes to LexicalClaim (200)
4. ratify-matcher_extension fails loudly (501 "handler not yet
implemented")
5. all 4 trace steps visible in detail response
6. no cross-contamination between math and cognition queues
teaching + runtime suites green (28 + 20 passed).
Brief-gap note: canonical_bytes() excludes proposal_id and serialises
evidence pointers as hashes only. D1 loader derives proposal_id via
sha256(line_bytes) and re-runs decompose_audit() to recover full trace
for read_math_proposal(). This works but means the JSONL cannot be
loaded without the original audit file. If a future wave needs
standalone JSONL loading, C1 should emit a richer format.
Add decompose_audit(audit_path) to teaching/math_contemplation.py.
Groups audit_brief_11.json refusal rows by
(refusal_reason, missing_operator), emits one
MathReaderRefusalShapeProposal per group of >=2 rows, each carrying a
4-step ReasoningTrace (observation -> grouping -> hypothesis ->
conclusion).
Determinism:
- Group iteration sorted by (refusal_reason, missing_operator).
- Evidence per group sorted by case_id.
- Output tuple sorted by proposal_id.
- 10x rerun -> byte-identical proposals + trace_ids.
Pure read-only: audit file is not mutated, no proposals written to
disk, no chat/field/generate/algebra imports.
Tests (tests/test_adr_0172_w2_decomposer.py): real-audit emission,
determinism (10x), evidence floor, change-kind dispatch over all four
heuristic branches, four-step trace, case_id sort, proposal_id sort,
empty input -> empty tuple, unmapped operator skip, missing file ->
FileNotFoundError, no-mutation contract.
Added to core test --suite teaching.
New module `teaching/math_contemplation_proposal.py` defines the
`MathReaderRefusalShapeProposal` dataclass — the math-domain analog of
`TeachingChainProposal` for the Tier-1 contemplation corridor.
- `build_proposal` enforces all seven invariants: math domain, ShapeCategory
enum membership, ≥2 evidence pointers, valid ChangeKind Literal, JSON-
serializable payload, ≥40-char wrong_zero_assertion, and non-None
reasoning_trace with a non-empty trace_id.
- `canonical_bytes` / `compute_proposal_id` produce stable sha256-based IDs;
evidence reduced to evidence_hash, trace to trace_id for stability.
- `ReasoningTrace` imported under TYPE_CHECKING only (W0/A1 not yet merged);
duck-typed at runtime via trace_id attribute.
- 16 tests cover all eight brief obligations plus freeze and sensitivity checks.
- `core test --suite teaching -q` green (17 passed).
Schema-only module defining ReasoningStep / ReasoningTrace with
byte-identical canonical serialization and sha256 trace_id derivation.
Replay-equivalence is enforced by:
- sorted-key JSON, no whitespace, ensure_ascii=False, allow_nan=False
- recursive rejection of float values in payloads (replay hazard)
- step_index monotonicity from 0
- empty trace rejected
- Literal-checked step_kind across all eight Tier 1+2 kinds
No runtime hook. No import from chat/field/generate/algebra.
Downstream (W1 ShapeProposal, W2 decomposer) consume this schema.
Tests: 12 new, full teaching suite green (17 passed).
The brief pack referenced `teaching/audit_evidence.py` in 3 spots
(A2 schema field, A2 read-required list, B2 algorithm step 3a). The
actual module on main is `teaching/math_evidence.py` (carries
`MathReaderRefusalEvidence` per ADR-0167).
Sonnet (A2 / PR #380) discovered the discrepancy and correctly used
the real module. This patch corrects the brief so Wave B operators
(B1 / B2) do not hit the same gap on dispatch.
No runtime change. Pure docs.
Coordination artifact for ADR-0172 Tier 1 dispatch. Six PRs in the
ADR (W0, W0.1, W1, W2, W3, W4) collapsed into a 4-wave DAG with two
concurrent briefs per wave A and B.
Operators are dispatched in their own UIs by pointing at the
section heading — "read §Brief A1" etc. Bundling options A/B/C
inside the doc let the operator choose CI economy vs wall-clock.
No runtime change. Pure docs.
Second implementation PR of the ADR-0170 wave. Extends the DCS injector
to emit ``CandidateOperation(kind='add')`` for acquisition verbs
alongside the existing ``CandidateInitial`` emission for possession
verbs. Proves the W1 type-widening with real emission of both union
members.
## What changes
### `generate/recognizer_match.py`
- New `_ACQUISITION_VERBS` frozenset (12 verbs: collect/get/receive/buy
inflections). Each member is a subset of `ADD_VERBS` so the downstream
CandidateOperation post-init whitelist accepts the matched_verb token.
- Extractor now accepts either possession OR acquisition verbs and
records `anchor_kind` (`"possession"` | `"acquisition"`) plus
`verb_token` in the parsed anchor schema.
### `generate/recognizer_anchor_inject.py`
- `inject_discrete_count_statement` dispatches on `anchor_kind`:
- `"possession"` → `CandidateInitial` (existing behavior unchanged)
- `"acquisition"` → `CandidateOperation(add)` (new)
- New helper `_build_operation_from_discrete_count_acquisition`
constructs the operation. Operand uses `_resolve_count_value`;
matched_verb uses `_locate_token` for round-trip ground check.
- Return type uses `InjectorEmission` from W1.
### Tests
- `tests/test_adr_0170_w2_dcs_acquisition_verbs.py` (new) — 22 tests:
- Verb-set membership pins
- Acquisition ⊂ ADD_VERBS sanity check
- Possession + Acquisition disjoint
- Extractor records anchor_kind correctly
- Injector emits CandidateOperation for acquisition verbs
- Possession path still emits CandidateInitial unchanged
- Deliberate exclusions (gained / donated / saved) still refuse
- Case 0050 hazard pinned (does/contemplates not in either set)
- Determinism + roundtrip_admissible passes
- Updated `tests/test_adr_0163_d2_discrete_count_injection.py` to
reflect new anchor schema fields (anchor_kind, verb_token).
- Updated `tests/test_adr_0170_w1_injector_type_widening.py` —
the DCS injector now legitimately returns
`tuple[InjectorEmission, ...]` (not narrower).
## Deliberate exclusions
These verbs are NOT in `_ACQUISITION_VERBS` and the extractor refuses
them — preserving wrong=0:
- `gained / gains / gain` — delta-of-attribute (weight, age), not
acquisition. Admitting as add-operation would risk wrong>0 on
questions that ask total state.
- `donated / donates / donate` — SUBTRACT semantics (actor gives away).
- `saved / saves / save` — ambiguous (time vs money vs effort).
Widening this set is operator-reviewable per `feedback-wrong-zero-
hazard-case-0050` discipline.
## ADR-0131.G.1 branch-disagreement discipline preserved
The regex parser already emits `CandidateOperation(add)` for
acquisition verbs via `ADD_VERBS` for single-word units. The new DCS
injector path emits the same kind of operation for multi-word units
(where the regex parser fails). Collapsed-tie when both paths emit
identical operations on overlapping shapes; no disagreement.
## Test plan
- tests/test_adr_0170_w2_dcs_acquisition_verbs.py: 22 passed (new)
- tests/test_adr_0163_d2_discrete_count_injection.py: ~30 passed
(existing tests updated for new schema fields)
- tests/test_adr_0170_w1_injector_type_widening.py: 6 passed
- tests/test_recognizer_skip_wrong_zero.py + brief_11b + brief_11 +
candidate_graph_wiring + candidate_domain_partition: passed
- evals/gsm8k_math/train_sample/v1: counts=correct=3 refused=47 wrong=0
unchanged (case 0023 still has S2/S3 downstream blockers; W2's value
is infrastructure, not direct lift)
## Hard invariants
- `wrong == 0` preserved (case 0050 hazard pin + deliberate verb
exclusions + roundtrip_admissible gate)
- ADR-0166: no new eval lanes
- No teaching-store / pack mutation
- ADR-0131.G.1 branch-disagreement discipline preserved (acquisition →
operation, not initial)
- Five-layer wrong=0 safety net (ADR-0163.D.2) intact and extended
## W3 NOT in this PR — honest skip
Initial plan was to bundle W2 + W3 (A1 currency_amount injector).
Inspection of the 4 actual `currency_amount` GSM8K refusals showed
none match A1's narrow form (`<ProperNoun> earns|charges $<amount>`):
| Case | Statement | Reason narrow form doesn't fit |
|---|---|---|
| 0019 | "this requires 3 vet appointments, which cost $400 each" | anaphoric subject + multi-quantity |
| 0026 | "Aaron and his brother Carson each saved up $40" | multi-subject + "each" |
| 0028 | "It cost $100,000 to open initially" | pronoun subject |
| 0043 | "Her mother gave her an additional $4, and her father twice as much" | multi-clause + comparative + transfer |
Shipping W3 as-designed would have re-introduced the dead-code pattern
#373 just cleaned up. Skipped honestly; ADR-0172 Tier 1's decomposer
(the next wave) will surface category-shape mismatches like this
programmatically.
* docs(ADR-0172): math-domain corpus-decomposition mechanism (Learning Arc analog)
Scoping ADR for the math-domain analog of cognition's
`teaching/contemplation.py` corpus-decomposition loop (Learning Arc
milestone 2026-05-25).
## What this ADR scopes
A mechanism that reads the math audit corpus and emits
`MathReaderRefusalShapeProposal` records — structural commonalities
across N refusal cases, paired with the candidate mechanism change
that would resolve them (matcher extension, injector sub-shape,
vocabulary addition, frame reclassification).
Today the operator does this decomposition by hand (reads
audit_brief_11.md, identifies the commonality across 21 DCS
refusals, scopes the matcher/injector extension, files a focused PR).
ADR-0172 shifts the decomposition to the engine, with HITL
ratification preserved.
## Sequencing — explicit
ADR-0172 ships AFTER ADR-0170 (injector contract widening),
ADR-0168 (FrameClaim handler), and ADR-0169 (CompositionClaim
handler — reserved). Without those substrates, the decomposer can
identify patterns but cannot route them to a ratification handler
that knows how to materialize them. Cognition's learning arc
followed this same sequencing: substrate first, then decomposer.
## Why this matters
ADR-0167 LexicalClaim shipped the math-domain wire from refusal →
evidence → operator-ratification. ADR-0172 closes the gap to the
engine-decomposes loop — the moment cognition's learning arc
qualitatively shifted from "engine refuses + operator authors" to
"engine teaches itself through reviewed correction."
The Learning Arc memory entry (2026-05-25) names that moment as
when measurable progress accelerated. ADR-0172 makes the math-domain
trajectory toward the same loop explicit in the queue.
## Hard invariants preserved
- wrong=0 by construction (proposals are evidence-only)
- ADR-0166: no new eval lanes
- No teaching-store / pack mutation
- No non-deterministic mechanism (rule-based grouping, not learned
classification)
- Cross-domain partition (ADR-0167 W2-C) preserves cognition
contemplation behavior
No code, no test, no eval, no pack change in this PR.
## Cross-references
- ADR-0056/0057 — cognition contemplation/proposal substrate (template)
- ADR-0167 + FOLLOWUPS §1 — parent evidence wire
- ADR-0168 + ADR-0168.1 — FrameClaim (ratification target)
- ADR-0169 (reserved) — CompositionClaim (ratification target)

- Memory: Learning Arc Milestone 2026-05-25 — the moment to recreate
- Thesis: decoding, not generating — the principle preserved
* amend(ADR-0172): add Tier 2 — intensional contemplation with test-and-learn loop
Per operator feedback during ADR-0172 review: the corpus-decomposition
mechanism should not only emit explicit rules (extensional) but also
develop inference (intensional) — recognizing structural equivalence
classes across surface variations without enumerating them.
## Tier 2 — intensional contemplation
Engine recognizes that 'Sam has 5 apples' and 'Sam collected 5 apples'
carry the same canonical proposition structure, without an explicit
verb-list extension. Emits MathReaderInferenceProposal records that
name structural equivalence classes rather than enumerable rules.
This is the thesis word the original draft missed: rationalization.
Tier 1 ratifies rules; Tier 2 ratifies inference.
## Test-and-learn loop
Tier 2 proposals carry held-out test evidence:
1. Decomposer surfaces hypothesis
2. Held-out subset of corpus reserved
3. Bridge applied to held-out cases; admissibility gates run
4. Outcome scored (positive / negative / neutral)
5. Negative-evidence proposals auto-rejected before HITL
6. Operator reviews proposal + test result, not bare claim
This makes Tier 2 thesis-coherent: engine decodes a structural
pattern, tests it against unseen corpus cases, surfaces the test
result. Wrong=0 cannot leak through — held-out test failures reject
internally.
## Updated implementation outline
Tier 1 wave: W1-W4 (schema, decomposer, CLI, workbench integration)
Tier 2 wave: W5-W9 (schema, equivalence-class recognizer, test-and-learn
loop, HITL integration, bridge application path)
## Hard invariants preserved at both tiers
- wrong=0 by construction (Tier 1: evidence-only proposals; Tier 2:
held-out test rejects wrong-admitting bridges internally)
- ADR-0166: no new eval lanes
- No non-deterministic mechanism (rule-based grouping + deterministic
test-and-learn, not learned classification)
- Cross-domain partition preserves cognition contemplation behavior
* amend(ADR-0172): split Tier 2 test-and-learn into two-arm confirmation
Per operator feedback during ADR-0172 review: 'confirm against known
facts/prior solutions' is the missing arm. The Tier 2 test-and-learn
loop now has BOTH:
- Arm 1 (negative / wrong=0 on held-out refusals) — already drafted
- Arm 2 (positive / known-good preservation) — NEW
Arm 2 inherits ADR-0057's replay-equivalence contract: any
inferential bridge that would change a currently-correct outcome is
REJECTED INTERNALLY before reaching HITL, even if the new outcome is
defensible. Existing truth survives; new truth is gated.
Both arms must PASS or be neutral. Either arm rejecting → proposal
does not reach the operator. This makes the engine's reasoning
provably conservative: it confirms against truth it already knows AND
truth it hasn't yet decided.
The 5-step proposal lifecycle is updated to reflect both arms +
test-set partition + per-case verdict tables in the emitted proposal.
No code change. No runtime effect.
* amend(ADR-0172): add foundational reasoning-articulation substrate
Per operator feedback: for the engine to infer/test/learn from
feedback, it must first be able to ARTICULATE its own reasoning in a
structured, persistent, replayable form.
Articulation is the project thesis's 5th anchor ("listen → comprehend
→ recall → think → articulate → learn from reviewed correction →
replay"). Today CORE articulates SURFACE (templated realizer output)
but does not articulate REASONING — the inference chain that took the
engine from refusal corpus to hypothesis to proposal.
Without reasoning-articulation, none of the three loops can work:
- Loop 1 (self-test) has nothing to record about what it tested or why
- Loop 2 (HITL review) sees a black-box conclusion, not inference chain
- Loop 3 (feedback) has no specific step the operator can target with
a rejection rationale
## Substrate: ReasoningTrace schema
Every proposal carries a typed, content-addressable
ReasoningTrace recording each inference step:
ReasoningStep:
step_kind: observation | grouping | abstraction | hypothesis |
test_design | test_application | test_result | conclusion
input_pointers: prior steps + evidence rows
claim: human-readable assertion at this step
justification: why the engine made the claim
output_payload: type-discriminated by step_kind
The trace is byte-identical across replays of the same corpus +
verdict history. Inherits CORE's existing determinism discipline.
## Sequencing
Articulation ships FIRST (new W0 wave) — it is the prerequisite for
Tier 1 and Tier 2 and Loop 3. Each downstream wave emits or consumes
ReasoningTraces.
## Hard invariants preserved
- Deterministic-replay (trace byte-identical under same inputs)
- ADR-0057 replay-equivalence (trace IDs stable across reruns)
- No non-determinism added (rule-based step emission, not learning)
- ADR-0166: no new eval lanes
No code, no test, no eval, no pack change in this PR.
The G.2 test \`_comparative_clause_refusal_count\` reads \`report.json\`
and counts refusals whose reason quotes a statement clause containing
comparative anchors ("more/less than", "twice as many", etc.). After
#359's wrong=0 fix, the candidate-graph emits two refusal-reason
families that both quote a statement:
1. "no admissible candidate for statement: '...'" — parser-path
refusal (the comparative-parse-failure family this metric tracks).
2. "recognizer matched but produced no injection for statement:
'...'" — recognizer-path refusal; the quoted statement may
incidentally contain comparative anchors but the refusal cause is
the missing injector, NOT the comparative parse.
The pre-#359 counter only saw family (1) reasons; post-#359 it
over-counts whenever a recognizer-path refusal quotes a statement
containing comparative anchors. This was the test failure A2's PR
(#369) and the cleanup PR (#373) both surfaced.
## Fix
Filter the counter to exclude family (2) explicitly. Recognizer-path
refusals are tracked separately by the recognizer-wiring test suite;
they don't belong in the G.2 metric.
Result on current main:
- total statements with comparative anchors in refusal reasons: 2
- parser-path: 1 (case 0009, the legitimate G.2-tracked refusal)
- recognizer-path: 1 (filtered out — incidental anchor in #359-format reason)
- G.2 metric correctly reports 1 < baseline 2 → assertion passes
## Also: refresh report.json
The checked-in \`report.json\` was generated pre-#359 with the legacy
refusal-reason format. The runner now emits the new format on every
run; checking in the current output makes the baseline reproducible
and clears the CI friction that A2 originally flagged.
## Test plan
- tests/test_adr_0131_G2_comparatives.py: 25 passed (was 24 pass / 1 fail)
- tests/test_adr_0131_G4_multi_clause.py + G5_aggregate + S1_rate_events: 105 passed
- tests/test_brief_11b_audit_artifact + step2_lexicon + recognizer_skip + brief_11_audit + wiring + partition + adr_0163_d2: 89 passed
- Total: 219 passed
## Hard invariants
- No runtime change
- wrong=0 invariant preserved
- ADR-0166: no new eval lanes
- No teaching-store / pack mutation
First implementation PR of the ADR-0170 wave. Type-level widening only:
the recognizer-injector dispatch now returns
``tuple[InjectorEmission, ...]`` where
``InjectorEmission = CandidateInitial | CandidateOperation``.
The existing ``inject_discrete_count_statement`` continues to emit only
``CandidateInitial`` — the widening unlocks but does not exercise
operation emission. Subsequent W2-W5 PRs ship the per-injector emission
shapes:
- W2 — DCS-S1 acquisition verbs (CandidateOperation(add))
- W3 — A1 currency_amount (CandidateInitial reimplementation)
- W4 — A3 multiplicative_aggregation (CandidateInitial(product))
- W5 — A4 temporal_aggregation (deferred until apply_rate primitive)
## Changes
### `generate/recognizer_anchor_inject.py`
- New `InjectorEmission = Union[CandidateInitial, CandidateOperation]`
- `inject_from_match` return type widened to
`tuple[InjectorEmission, ...]`
- `__all__` exports `InjectorEmission`
- Documentation comment names ADR-0170 §"Implementation outline"
### `generate/math_candidate_graph.py` (admissibility dispatch)
The per-statement admission loop now dispatches admissibility on the
concrete candidate type:
if isinstance(c, CandidateInitial):
if _initial_admissible(c): admitted.append(c)
elif isinstance(c, CandidateOperation):
if roundtrip_admissible(c): admitted.append(c)
No new admission semantics — each type is gated by the predicate it was
already gated by elsewhere in the codebase. The dispatch unifies the
injector path with the parser path.
### `tests/test_adr_0170_w1_injector_type_widening.py` (new)
- Pin: `InjectorEmission` union members are exactly the two candidate types
- Pin: `inject_from_match` return type is widened
- Pin: `inject_discrete_count_statement` still emits CandidateInitial (W1
is type-level only)
- Hazard pin: case 0050 remains refused
- Hazard pin: unparseable-verb refusal path (#359) unchanged
- Anti-regression: canonical DCS narrow-form extraction still works
## Test plan
- tests/test_adr_0170_w1_injector_type_widening.py: 6 passed (new)
- tests/test_adr_0163_d2_discrete_count_injection.py: 21 passed
(existing D.2 v1 injector regression)
- tests/test_brief_11b_audit_artifact.py + step2_lexicon +
recognizer_skip_wrong_zero + brief_11_audit: 55 passed
- tests/test_candidate_graph_recognizer_wiring.py: 7 passed
- tests/test_candidate_domain_partition.py: 5 passed
- tests/test_adr_0131_G2_comparatives + G4 + G5 + S1_rate_events:
130 passed
- Total: 225 passed
- evals/gsm8k_math/train_sample/v1: counts=correct=3 refused=47 wrong=0
(unchanged; verified no behavioral regression)
## Hard invariants
- `wrong == 0` preserved (admissibility dispatch is type-aware but
semantically identical to the parser path's gating)
- ADR-0166: no new eval lanes
- No teaching-store / pack mutation
- Five-layer wrong=0 safety net (ADR-0163.D.2) intact
- Reader path unchanged
Three concrete cleanup items from the day's work, per the
cleanup-as-you-find memory principle.
## 1. Remove inject_rate_with_currency stub
PR #369 (A2 rate_with_currency) shipped a function that always returns
() with an extensive docstring documenting the Rate-not-in-SentenceChoice
schema gap. The function is dead at runtime — `_INJECTORS.get(category)`
returning None has the same downstream behavior as the function
returning (). The 16 tests pinned the empty-tuple return; the case-0050
hazard pin is duplicated in test_recognizer_skip_wrong_zero.py and
test_brief_11b_step2_lexicon.py.
The schema gap is now properly documented in ADR-0170 (PR #372). A
dispatch-table comment at the removal site retains the at-code pointer
to that ADR for anyone wiring a new injector.
Removed:
- `inject_rate_with_currency` function in generate/recognizer_anchor_inject.py
- Its `_INJECTORS` dispatch table entry
- Its `__all__` export
- tests/test_injector_rate_with_currency.py (371 lines, 16 tests)
## 2. Remove docs/handoff/GPT55-MOBILE-DISPATCH.md
Single-session travel-time scaffolding. The 5 tasks it named are
complete or superseded by ADR-0170's findings. Pure historical artifact.
## 3. Remove docs/handoff/WAVE-NEXT-INJECTORS.md
Superseded by docs/handoff/WAVE-NEXT-REVISED.md, which captures
everything load-bearing from the original brief in its A1–A4 findings
table. The "kept for history" justification didn't survive scrutiny:
the document was misframed (over-promised lift; misframed schema work
as injector work). Lessons captured in REVISED + ADR-0170.
Updated cross-references:
- WAVE-NEXT-REVISED.md: removed the "supersedes ... kept for history"
pointer; tightened cross-reference list
- ADR-0167-FOLLOWUPS.md §7: rewrote pointer to name ADR-0170 + REVISED
as the live plan rather than "the original is retained"
## Test plan
- 219 tests passed across G.2/G.4/G.5/S1/Brief 11/B1/B11A/wiring/partition/DCS-D.2
- evals/gsm8k_math/train_sample/v1/report.json untouched (regen
surfaces a separate stale-baseline test issue — out of cleanup scope)
- No runtime behavior change
## Net impact
- 5 files removed (~1200 lines)
- 1 file modified for explanatory comment (~30 lines)
- 2 doc files updated to remove dangling cross-references
- 0 behavioral change
