* feat(ADR-0141): multiply as CGA dilator versor (positive non-zero)
Adds `multiply(scale)` to `generate/math_versor_arithmetic.py` as the
standard CGA dilator for multiplicative scaling along e1, restricted to
`scale > 0`. All ten ADR-0141 assertion families pass.
Preliminary measurement confirmed:
N = n_o ∧ n_inf: component -1 at index 15 (blade (3,4) = e4∧e5)
N² = +1.0 (pure scalar) → closed-form D_s = cosh(α/2) + sinh(α/2)·N
n_o · n_inf = -1; n_o² = n_inf² = 0
Because N² = +1, the cosh/sinh expansion is exact in float64 and
D_s · ~D_s = cosh² − sinh² = 1 holds to machine epsilon.
The sandwich D_s·X·~D_s produces a null point with n_inf normalization
1/s. `decode_quantity` is updated to divide by that factor, recovering
value · s. For translator outputs (normalization = 1) the result is
identical to the previous direct e1 read; all 152 prior add/subtract
tests pass unchanged.
`embed_quantity` is updated to embed directly in float64, eliminating
float32 quantization error for values like 0.01 (float32(0.01) ≠ 0.01);
all prior test-case values were exactly representable in float32.
* docs(ADR-0141): add decision document for multiply-as-dilator spike
The ADR doc was drafted in a separate branch and not present when the
implementation worktree was created from origin/main. Adding it now so
the decision record lands on main with the implementation it specifies.
Content unchanged from the draft — same spec the implementation already
satisfies (10 assertion families, fixed test cases, falsification
discipline, deferred scope for negative / zero / divide / Rate).
No code or test changes in this commit.
Extends generate/math_versor_arithmetic.py with one new function:
def subtract(addend: float) -> np.ndarray:
return translator(-float(addend))
Single-line delegate to translator(); no new algebra.
Adds tests/test_arithmetic_subtract_and_group.py covering all nine
ADR-0140 acceptance families:
Families 1-6 (ADR-0139 families applied to subtract):
1. Embedding well-formedness — null cone preserved for subtract cases
2. Translator-of-negative well-formedness — versor_condition < 1e-6
3. Closure — sandwich result stays on null cone
4. Arithmetic correctness — decoded value == a − b within 1e-9
5. Replay determinism — byte-identical across runs
6. Composability — subtract(c) ∘ subtract(b) decodes to a − b − c
New group-property families (structural verification of ADR-0139 claim):
7. Inverse composition — T_{-b} * T_b = identity (max residual: 0.000e+00)
8. Round-trip closure — versor_apply(T_{-b}, versor_apply(T_b, X)) → (a, u)
9a. Sum composition — T_a * T_b = T_{a+b} (max residual: 0.000e+00)
9b. Commutativity — T_a * T_b byte-equals T_b * T_a (all 10 cases)
All 96 tests pass. Group residuals are exactly 0.0 in float64.
The additive subgroup of Cl(4,1) translators along e1 is abelian and
closed; ADR-0139's algebraic claim holds at the group level.
First step of the Engine A lift program (CLAUDE.md commits the project to a
single deterministic cognitive engine; Engine B / math pipeline was always
intentional scaffolding per math_solver.py:24). Proves the load-bearing
unknown: one arithmetic operation can be represented as a closed versor at
the required tolerance, with no new normalization and no weakened invariant.
Scope (frozen by ADR-0139):
- One operation: add
- Single-axis embedding: quantities on e1 axis
- No graph wiring, no pipeline integration, no GSM8K case routed
- Unit carried as caller metadata
Construction:
- embed_quantity(v, u) = embed_point([v, 0, 0]) (existing CGA primitive)
- translator(b) = 1 - 0.5 * (b*e1 * n_inf) (textbook CGA translator)
- decode_quantity(F, u) = (F[1], u) (e1 coordinate)
Measured values (all 11 fixed cases + composability):
a b vcond(T) |<R,R>| decode_err
0.0 0.0 0.000e+00 0.000e+00 0.000e+00
0.0 1.0 0.000e+00 0.000e+00 0.000e+00
1.0 0.0 0.000e+00 0.000e+00 0.000e+00
3.0 4.0 0.000e+00 0.000e+00 0.000e+00
7.0 -3.0 0.000e+00 0.000e+00 0.000e+00
0.25 0.75 0.000e+00 0.000e+00 0.000e+00
1.5 2.5 0.000e+00 0.000e+00 0.000e+00
-5.0 5.0 0.000e+00 0.000e+00 0.000e+00
-2.0 -3.0 0.000e+00 0.000e+00 0.000e+00
100.0 1.0 0.000e+00 0.000e+00 0.000e+00
1.0 100.0 0.000e+00 0.000e+00 0.000e+00
compose (2, 3, 5) → 10: |<R2,R2>| = 0.000e+00, decode_err = 0.000e+00
Every residual is exactly 0.0 in float64. The construction is algebraically
closed: T_t * reverse(T_t) = 1 - 0.25*B^2 where B = t*n_inf, and B^2 = 0
because (e14)^2 + (e15)^2 = -1 + 1 and cross-terms cancel. No machine-epsilon
drift accumulates because the relevant cancellation happens at the algebraic
level before float arithmetic.
ADR-0139 acceptance items 1-6 (one parametrized test family each):
1. Embedding well-formedness — test_family1_embedding_is_null (11 cases)
2. Translator well-formedness — test_family2_translator_unit_versor (11 cases)
3. Closure — test_family3_sandwich_preserves_null (11 cases)
4. Arithmetic correctness — test_family4_decode_matches_sum (11 cases)
5. Replay determinism — test_family5_replay_byte_identical (11 cases)
6. Composability — test_family6_two_translators_compose (1 case)
Total: 56 tests, all passing.
Lift program decision: proceeds. Follow-on ADRs (subtract, multiply, Rate,
compare, MathProblemGraph → PropositionGraph, pipeline integration, first
GSM8K case end-to-end through Engine A) are now justified by a concrete
algebraic foundation rather than design speculation.
Out of scope per ADR-0139:
- No modifications to algebra/, core/cognition/, chat/, math_solver.py,
math_verifier.py, math_realizer.py, math_candidate_parser.py
- No GSM8K runner changes
- No pack changes
- Engine B continues serving GSM8K unchanged; the 3/50 admission set is
preserved
CLI lanes intentionally not run — main has known test-rot orthogonal to
this PR. The 56 new tests are self-contained and the diff touches only
three new files.
S.4 extends initial-state parsing with two closed subject-slot widenings:
- Indefinite-article: `A <noun> has N <unit>` (gsm8k-0046 sentence 1)
- Prepositional-prefix existential: `In a <place>, there are N <unit>...`
(gsm8k-0038 sentence 1)
Design choice: sibling regexes (_INITIAL_HAS_INDEF_RE,
_INITIAL_THERE_ARE_PREFIX_RE) rather than widening the global _ENTITY
pattern — preserves existing behavior across all other initial-state
extractors (cascade-safety).
Per the S.x corridor discipline: no new short-circuit; new candidates
flow through extract_initial_candidates and the existing graph machinery.
No solver/graph/verifier changes.
Honest delta:
- Direct admissions: 0 (admission set unchanged at {0014, 0018, 0042})
- Barrier shifts: +2 (gsm8k-0038: novel_initial_form → compound_comparative;
gsm8k-0046: novel_initial_form → fraction_operand)
- wrong == 0 on every lane
Bundled with this PR for ledger currency:
1. tests/test_rescan_v3_invariants.py refactored to read frozen on-disk
v3 artifacts only (no more re-running build_rescan against live
parser). The previous design tied a historical snapshot to live code
and broke the moment any new phase landed.
2. rescan_v4.py + refusal_rescan_v4.json + refusal_taxonomy_v4.json +
tests/test_rescan_v4_invariants.py — the current live snapshot.
Shifts: exactly 2 (0038, 0046). Same pattern as v3.

- Tests: 47/47 pass (12 new for classifier, inverted patterns, 0018 end-to-end).
Rebases onto current main (dec98ea, post-G.1/G.3.1/G.4/promotion).
Parser:
- Extend _COMPARE_MULT_ANCHOR_RE anchor alternation to include 'quarter'
and 'third'; add optional 'a\s+' article prefix so "a quarter as many"
and "a third as many" parse. Both anchors are in COMPARE_MULTIPLICATIVE_ANCHORS
and the round-trip factor-divisor table ("quarter":4, "third":3), so
round-trip checks pass. quarter→0.25 (exact), third→1/3 (float).
- Add _ANCHOR_TO_FACTOR entries for quarter and third.
Gate regex (test_adr_0131_G2_comparatives.py):
- Widen _COMPARATIVE_STATEMENT_PATTERNS multiplicative pattern from
'\d+\s+times' to '\w+\s+times' to match word-number forms ("four times")
that would be missed by the digit-only pattern if a future GSM8K case
contains one in a still-refused statement.
Cases (31 total, was 24):
- G2-mul-frac-005/006: two 'quarter' cases (fraction direction now has
half×4 + quarter×2 + third×1 = 7 cases, was 4 all-half).
- G2-mul-frac-007: 'third' case.
- G2-refuse-006: hyphenated 'one-third' pins the closed-anchor boundary.
- G2-refuse-007: 'double as many' pins the deferred grammar shape.
Tests (25, was 21):
- Add quarter and third parametric entries to test_multiplicative_direction_admits.
- Add one-third and double-as-many refusal params to test_refusal_cases.
- Add quarter/third to test_direction_literals_closed_set.
- Update test_runner_per_category_minima comment to reflect new counts.
ADR: document quarter/third admission, updated case table, deferred list.
report.json: refreshed to 31 cases, wrong==0 preserved.
Cognitive capability: extend bounded grammar to admit acquisition/action
verbs (buys, bought, collected, saved, saved-up, makes, sells) as
operation-kind entries, and pure-possession verbs (had, started, started-with)
as initial-possession anchors.
What invariant proves correctness:
- wrong == 0 across all G1 curated cases (20/20) and GSM8K probe (0 wrong/50).
- versor_condition and field invariants untouched — no algebra-path changes.
- Round-trip filter (math_roundtrip.roundtrip_admissible) unchanged.
Which CLI suite / eval proves the lane:
pytest tests/test_adr_0131_G1_verb_classes.py — 15/15 pass
pytest tests/test_adr_0126_runner_wiring.py — 9/9 pass (3 regressions fixed)
pytest tests/test_adr_0131_{1,3}_*lane.py — 17/17 pass
pytest tests/test_adr_0131_G_gsm8k_coverage_probe.py — 8/8 pass
pytest tests/test_gsm8k_math_runner.py — 11/11 pass
Key architectural change:
Acquisition verbs that also appear in ADD_VERBS/SUBTRACT_VERBS were
previously listed in _INITIAL_HAS_RE, causing branch-disagreement refusals
when a canonical 'has' initial preceded an acquisition sentence for the
same entity. Fix: narrow _INITIAL_HAS_RE to pure-possession anchors only
(has/have/had/started); acquisition verbs remain exclusively in KIND_TO_VERBS.
The solver's default-from-zero means 'Sam buys 5 apples. How many does
Sam have?' resolves as 0+5=5 without any initial-possession candidate.
Optional verb particle (up/down/out/...) added to _op_pattern to handle
'saved up N', 'picked up N' etc.
No changes to binding graph, solver, verifier, or versor/CGA algebra.
No stochastic generation, approximate recall, or hidden normalization.
Trust boundaries unaffected — no new dynamic imports or user-input paths.
Two remaining sites that used _resolve_value() as a raw numeric operand:
1. _build_compare_additive (line 924): `delta_value = _resolve_value(delta_value_raw)` passed
a _ResolvedValue to Quantity, swallowed by the try/except — caused 7 G.2 additive-comparative
tests to silently return zero candidates.
2. Dual-unit initial extractor (line 1385): `_resolve_value(value_raw).value` with type: ignore —
replaced with explicit rv = ...; if rv is None: return [] pattern for clarity.
Regenerates G2 comparatives report.json (24/24 pass, wrong=0 unchanged).
Four axes deferred from ADR-0131.G.3 (PR #183):
1. Fractions end-to-end: new _INITIAL_FRACTION_OF_RE extractor handles
`N/M of [a/an] <unit>` shape; _resolve_value already handles N/M arithmetic.
2. Multi-currency: _MONEY_SYMBOL widened to six symbols; _CURRENCY_SYMBOLS table
+ _resolve_currency dispatcher; ¢/€/¥/₱ wired end-to-end. £/pound sterling
deferred to G.3.2 (question extractor's single-token unit slot cannot parse
two-word surface "pounds sterling").
3. Multi-token cardinals: dedicated _MULTI_WORD_CARDINAL_RE extractor (approach a)
delegates to parse_compound_cardinal; avoids greedy unit-slot boundary ambiguity
from widening _VALUE.
4. Word-num-adjective: optional adjective group added to _INITIAL_HAS_RE and
_MULTI_WORD_CARDINAL_RE; closed adjective list identical to _CONJ_OBJECT_RE.
Also fixes six pre-existing G4 type bugs where _resolve_value() result was used
directly as a numeric operand (TypeError: _ResolvedValue is not a number).
Axis lane v1_1: 20/20 solved_correct, 0 wrong, 8/8 refusals, overall_pass=True.
GSM8K probe: 0/50 admission_rate unchanged, admitted_wrong=0 (safety rail intact).
42/42 new tests pass; parent v1 lane (26/26) unaffected.
Highest-risk axis of the ADR-0131.G capability iteration: within-
sentence multi-clause composition. Four extractors land in the
candidate-emitting parser; no graph-side or solver changes.
Parser extension (generate/math_candidate_parser.py)
- _conj_subject_each_candidates: '<A> and [his/her/their <kin>] <B>
each <verb> <N> <unit>' → 2 CandidateInitial (one per actor).
- _conj_object_candidates: '<E> has <N1> <unit1> and <N2> <unit2>' →
2 CandidateInitial for the same entity; same-unit conjuncts refuse
(would silently collide under solver overwrite-on-collision).
- _embedded_quantifier_candidates: '<E> has <N> <container> with <M>
<unit> in each [<container>]' → 1 derived CandidateInitial
(value=N*M).
- _embedded_quantifier_candidates (conj branch): '... <N1> <C> with
<M1> <U> in each ... and <N2> <C> with <M2> <U> in each ...' → 1
SUM CandidateInitial (value=N1*M1+N2*M2); mixed-unit refuses.
- CandidateInitial anchor whitelist widened to include
saved/earned/got/received/bought/made/paid (and inflections) —
narrow widening needed for the conjoined-subject-each shape.
Closed-set discipline
- Distributive 'each' only — 'each ... together/altogether' refuses.
- Two-way conjunction only — 3-way refuses by non-match.
- Cross-sentence coreference stays refused (within-sentence axis).
- Ambiguous 'each' scope refuses (container2 must agree).
Curated axis lane (32 cases)
- evals/math_capability_axes/G4_multi_clause/v1/cases.jsonl:
conj_subject_each ×6, conj_object ×6, embedded_quantifier ×6,
conj_embedded ×6, refusal ×8.
- evals/math_capability_axes/G4_multi_clause/v1/runner.py +
report.json: deterministic; wrong==0 gate; byte-equal across runs.
Tests (26 new)
- tests/test_adr_0131_G4_multi_clause.py: per-shape emission,
refusal probes (parametric), distributive-only policy,
cross-sentence refusal, runner byte-equality, GSM8K-probe gate.
GSM8K-probe gate (chosen: multi-clause refusals ↓)
- evals/gsm8k_math/train_sample/v1/report.json (candidate-graph
probe): multi-clause statement-refusal count 2 → 1. Case 0042
('Ella has 4 bags with 20 apples in each bag and six bags with 25
apples in each bag.') moves from statement-clause refusal to
question-layer refusal. Case 0026 ('Aaron and his brother Carson
each saved up $40') stays refused on the '$' value slot
(deferred to G.3 numeric-literals axis).
- evals/gsm8k_math/train_sample/v1/train_sample_coverage_report.json
(legacy probe): refreshed, byte-identical (legacy parser
untouched).
B3 + candidate-graph + GSM8K probe lanes all pass (95/95
regression). wrong==0 preserved everywhere — load-bearing for the
highest-risk axis.
First capability-axis iteration after ADR-0131.G baseline. Extends the
candidate-graph parser's <value> slot to recognize:
- Money symbol literals: $N and $N.NN (1-2 decimals); $N.NNN refused
- Money word forms: N dollars / N cents
- Hyphenated multi-word cardinals: twenty-five, ninety-nine, ...
All money values normalize to integer cents, unit 'cents' — pack-aligned
with en_units_v1's canonical_unit='cent' for the money dimension.
en_numerics_v1's parse_compound_cardinal handles hyphenated cardinals.
Parser changes (generate/):
- math_candidate_parser.py: _VALUE alternation widened; _resolve_value
refactored to return _ResolvedValue|None carrying optional unit
override; _INITIAL_HAS_RE unit slot made optional; dollar/dollars →
cents normalization at candidate build.
- math_roundtrip.py: new _unit_grounds helper (money-aware); _value_grounds
widened for the three new literal shapes; roundtrip_admissible uses
_unit_grounds for the unit check.
- math_candidate_graph.py: _initial_admissible and _question_admissible
use _unit_grounds.
New axis lane (evals/math_capability_axes/G3_numerics/v1/):
- 26 curated cases (20 positive across 4 classes + 6 refusal probes)
- runner.py wraps _score_one_candidate_graph; byte-equal report.json
- 20/20 positive solved correct; 6/6 refusal probes refused typed;
solved_wrong == 0; overall_pass == True
Tests: 27/27 in 0.19s. 420 existing candidate-parser/math-parser/pack
tests still green. GSM8K probe safety rail (admitted_wrong == 0)
preserved.
Honest scope-limit (documented in ADR): admission_rate on the GSM8K
probe stays at 0/50 because (a) the probe currently consults the legacy
parser path, not the candidate-graph pipeline G.3 extends, and (b) most
money-bearing GSM8K cases fail first on verb (G.1) or multi-clause (G.4)
shape, not on the money literal. The axis lane is the load-bearing
measurement for this iteration. Reserved follow-up: a small probe-
infra ADR to switch run_coverage_probe.py to the candidate-graph
pipeline.
Out of scope, deferred to G.3.1: fractions end-to-end (resolver supports
N/M but no axis cases), multi-currency (¢ € £ ¥ ₱), space-separated
multi-word cardinals (one hundred), word-number-adjective compositions
(five full boxes).
Wire compare_additive / compare_multiplicative extractors into the
candidate-emitting sentence parser, closing the deferred phase flagged
at generate/math_candidate_parser.py:30.
Capability axis: comparatives (additive + multiplicative)
- generate/math_candidate_parser.py: new _compare_additive_candidates,
_compare_multiplicative_candidates, _compare_nested_candidates
emitting CandidateOperation records keyed to the four
Comparison.direction literals registered in ADR-0123.
- Closed-set anchor alternation; 'less' admitted as surface synonym of
'fewer'; reference slot widened to admit "the number/amount of <unit>"
for nested forms.
- Nested 'A has N more <unit> than M times <REF>' emits two flat
candidates (additive + multiplicative); binding-graph picks the
admissible composition or refuses (no solver stub).
Curated axis lane (24 cases)
- evals/math_capability_axes/G2_comparatives/v1/cases.jsonl:
8 additive / 8 multiplicative / 3 nested / 5 refusal
- evals/math_capability_axes/G2_comparatives/v1/runner.py +
report.json: deterministic, wrong==0 gate, byte-equal across runs.
Tests (21 new)
- tests/test_adr_0131_G2_comparatives.py: per-direction at-least-one
passing, nested-both-emitted, closed-set refusal, runner
byte-equality, GSM8K-probe gate (comparative-clause refusals
strictly decrease).
GSM8K-probe gate (chosen: comparative-clause refusals ↓)
- evals/gsm8k_math/train_sample/v1/report.json (candidate-graph
probe): comparative-clause refusal count 2 → 1 (case 0009 'Jen has
10 more ducks than four times the number of chickens' moves from
statement-clause refusal to question-layer refusal). admitted_wrong
remains 0; admission_rate unchanged (downstream composition is a
follow-up ADR).
- evals/gsm8k_math/train_sample/v1/train_sample_coverage_report.json
(legacy probe): refreshed, byte-identical (legacy parser untouched).
B3 + candidate-graph + GSM8K probe lanes all pass (90/90). Direction
vocab stays closed to {more, fewer, times, fraction}; wrong==0
preserved everywhere.
Refines BoundUnknown from "the symbol whose value the solver determines"
to "the symbol at a specific temporal/state index with a specific
question-form". Two new required fields on BoundUnknown — state_index
(initial/terminal/Operation(operation_index)) and question_form
(count/rate/total/difference/ratio/identity) — populated by the new
pure-function resolver in generate/binding_graph/question_target.py.
The adapter (ADR-0133) now delegates Unknown -> BoundUnknown construction
to bound_unknown_from_math_problem_graph. No runtime wiring, no solver
invocation. Phase 5 (bounded-grammar / B3 integration) remains deferred.
Refusal-first via the new QuestionTargetError (sibling of AdapterError /
AdmissibilityError). Closed reason vocab: not_a_math_problem_graph,
unknown_entity_not_in_entities, apply_rate_unit_mismatch,
unmappable_question_form. Closed precedence rule on question_form
documented in ADR-0135 (compare_multiplicative > compare_additive >
apply_rate{numerator|denominator unit-match} > count); ambiguity refuses.
SemanticSymbolicBindingGraph.__post_init__ gains a cross-collection
guard: Operation(operation_index) must satisfy operation_index <
len(equations). canonical_string emission widened to include
state=... form=... tokens (hash differs from Phase 3 main by design —
not a regression; byte-equal across runs preserved).
Parents: ADR-0132 / ADR-0133 / ADR-0134.
Tests: +70 new (45 unit in test_binding_graph_question_target.py +
25 integration in test_binding_graph_adapter_question_target.py); 5
Phase 1+3 BoundUnknown fixtures migrated. Total binding-graph lane
295/1 pass (1 pre-existing test_symbol_binding_uses_slots failure on
Python 3.14, unrelated to Phase 4 — exists on origin/main). Pyright
clean on new and modified files. No edits to algebra/, chat/, core/,
or runtime hot path. Field invariant untouched.
Wires deterministic, refusal-first dimensional analysis into the
binding-graph adapter. Every BoundEquation emitted by
bind_math_problem_graph now carries either admissibility_status='admitted'
+ populated unit_proof or admissibility_status='refused' + typed
refusal_reason. No silent coercion; no invented units; no solver.
Adds:
- generate/binding_graph/units.py — pure unit algebra over a 6-dim
integer exponent vector (length, time, mass, money, count,
temperature). Closed vocabulary loaded once from en_units_v1
(ADR-0127) and memoized; composite "<num>_per_<denom>" resolved
recursively; conservative depluralization; refusal-first.
- generate/binding_graph/admissibility.py — check_admissibility with
per-operation-kind dispatch over the closed 8-string vocab, typed
AdmissibilityError (closed reason set), frozen UnitProof.
- ADR-0134 documenting the contract, invariants, and Phase 4-5
deferrals.
Adapter changes are surgical: synthesizes operand-literal symbols where
the verifier needs them (op<NNN>__multiplicand / __divisor / __rate),
then stamps each equation via check_admissibility. Input/output types
unchanged; bind_math_problem_graph still byte-equal across runs.
Tests: 226 total in the binding-graph lane (110 Phase 1+2 still pass; 47
units + 40 admissibility + 29 adapter-units new). Pyright clean on all
new files. No runtime wiring outside generate/binding_graph/.
Phase 4 (question-target binding) and Phase 5 (B3 / bounded grammar)
remain deferred per the brief.

* test(ADR-0131.1.B): reconcile v1 expectations to v1.B scope expansion
The v1.B refactor (univariate int → sparse multivariable Fraction) deliberately
admits multivariable polynomials and constant-denominator division. The v1
dataset and tests pinned the old refusal behavior, so the lane runner reported
wrong=4 and 10 unit tests failed.
Reconcile:
- cases.jsonl: flip sym-eq-v1-0029 ('x+y' vs 'x+1') and sym-eq-v1-0030
('x/2' vs 'x') from expected=refused to expected=not_equivalent; rename
categories to multivariable_distinct / constant_denominator_distinct;
extend provenance with adr-0131.1b:scope-expanded.
- generated_cases.py: split _refusal_cases into scope_expanded (admits)
and templates (still refused); the first two adversarial cases move to
the scope-expanded list with expected=not_equivalent.
- test_math_symbolic_normalizer.py: replace test_undefined_variable and
test_unknown_operator_division with positive scope-expansion tests +
symbolic-denominator refusal; rewrite TestPolynomialInvariants for the
new terms/variables constructor (Polynomial(terms={...}, variables=(...)))
with float-rejection and zero-coef-collapse invariants.
- test_math_symbolic_equivalence.py: TestRefused.test_empty_left reason
string matches new normalizer error; flip multivariable + constant-
denominator cases to NOT_EQUIVALENT; add symbolic-denominator-refused
case; relax canonical_a assertion in test_a_normalizes_b_refuses (engine
now zeroes both on either-side refusal).
- report.json + manifest.json: regenerated; lane PASS 185/185 wrong=0.
Lane invariants reaffirmed by the new tests: wrong==0, refusal-first for
truly out-of-scope inputs (symbolic denominator, transcendental, malformed,
negative exponent), determinism via byte-equal report.
ADR-0131 Benchmark 1 substrate — the primary discriminator for the
mathematics_logic expert promotion under the architecture-aligned
benchmark composite proposed in ADR-0131.
WHAT LANDED:
generate/math_symbolic_normalizer.py
Deterministic univariate polynomial normalizer. Scope: single
variable, integer coefficients, +/-/*/** operators, parens, no
division, no transcendentals. Pipeline: tokenize -> recursive-
descent parse -> expand-and-collect -> canonical string. Refusal
is first-class via SymbolicError; out-of-scope inputs refuse
rather than guess (preserves wrong == 0).
generate/math_symbolic_equivalence.py
check_equivalence(a, b) -> EquivalenceVerdict
Returns EQUIVALENT / NOT_EQUIVALENT / REFUSED with canonical
strings + reason. Compares byte-equal canonical forms.
evals/math_symbolic_equivalence/v1/
cases.jsonl — 30 hand-curated cases across 18 algebraic
identity categories + 2 out-of-scope refusals.
Coverage: commutative, distributive, square +
cube of binomial, difference of squares, FOIL,
collect like terms, zero cancellation, factoring,
exponent combination, unary negation.
runner.py — CLI entry point. Loads cases, builds report,
writes JSON, exits 0/1 on gate pass/fail.
README.md — methodology, scope, dataset categorization,
exit criterion, baseline result.
tests/
test_math_symbolic_normalizer.py — 44 tests covering parser,
algebra primitives,
canonical-form invariants,
and every refusal path.
test_math_symbolic_equivalence.py — 16 tests on the public
check_equivalence API.
test_adr_0131_1_symbolic_equivalence_lane.py
— 8 tests gating the lane:
dataset integrity, exit
criterion, wrong == 0,
determinism (byte-equal
report across runs).
EMPIRICAL RESULT (the lane PASSED):
correct = 30 / 30 (100.0%)
wrong = 0 / 30 (wrong == 0 invariant satisfied)
refused = 0 / 30 (refusals all matched expected)
correct_rate = 1.00
exit_criterion: PASSED (>= 0.95 required)
CONTRAST WITH ADR-0127-0128 GSM8K TRAIN-SAMPLE RESULT (0/0/50):
This is the first benchmark on the mathematics_logic lane where
the architecture's structural strengths fully express. The result
is the empirical inverse of the GSM8K result — and that's
exactly the architecture-benchmark fit ADR-0131 was written to
re-target toward.
REGRESSION: 1033/1033 existing tests green across math + ADR-0126
+ pack ratification + runner. Zero regressions.
SCOPE DISCIPLINE (per ADR-0131.1 v1 plan):
v1 deliberately narrow (univariate, integer, polynomial). Future
ADR-0131.1.B expansions documented in README: multi-variable,
rationals, larger dataset (~500), sealed holdout per ADR-0119.7
pattern.
PARALLEL WORK (per ADR-0131 plan to run all 3 sub-phases concurrently):
- ADR-0131.2: CORE-native teaching-corpus eval (separate PR)
- ADR-0131.3: bounded-grammar word-problem set (separate PR)
These are independent of ADR-0131.1; no shared files, no
cross-PR coordination required beyond final composite gate.
Integrates en_units_v1 (#164) + en_numerics_v1 (#163) into the
ADR-0126 candidate-graph parser. Loader merge (re-exports from
numerics_loader.py give single import path), pack-aware unit
canonicalization (handles irregular plurals like feet/children
via lookup_unit), indefinite-quantifier refusal (ADR-0128.4 —
'some'/'many' emit no candidates, preserving wrong==0), and
widened initial-possession shapes:
- <Entity> has N <unit> [of <substance>] (ADR-0127 substance qualifier)
- There are N <unit> [in <place>] (implicit-subject shape)
Plus: pack-backed cardinal grounding in math_roundtrip._value_grounds
(widens word-number coverage from hard-coded 0-12 to full numerics
pack cardinal table + compound rule). Op-pattern trailing prep
alternation gains of/for/with for substance qualifiers.
REGRESSION: 1050/1050 tests green across math + ADR-0126 + ADR-0127
ratification + ADR-0128 ratification + runner.
EMPIRICAL RESULT (the Path-B trigger ADR-0126/0127/0128 named):
correct = 0/50 wrong = 0/50 refused = 50/50
on evals/gsm8k_math/train_sample/v1/cases.jsonl
Per ADR-0127's exit criterion (correct >= 10/50, wrong == 0):
**MISSED** — the full deterministic design (candidate-graph
topology + units pack + numerics pack + pack-aware parser) does
not move the GSM8K-math lane. This is the real Path-B trigger.
WHAT WORKS (synthetic verification, 6/6 cases solve end-to-end):
- 'Jan has 5 apples. Jan buys 3 apples. ...' -> 8
- 'Sam has 10 feet of rope. Sam uses 3 feet of rope. ...' -> 7
- 'There are 5 kids in camp. ...' -> 5
- 'Sam has 10 children. Sam loses 2 children. ...' -> 8
- (money + time-dimension variants pass)
WHY GSM8K STAYS AT ZERO: real GSM8K problems carry compound
linguistic structure (pronouns across statements, possessives,
subordinate clauses, multi-word entities, multi-step inference)
that no amount of pack vocabulary addresses. Per-sentence parse
rate improved measurably on simple shapes; joint problem-level
pass rate stayed at zero because every real problem contains at
least one sentence the parser still cannot handle.
Full results + Path-B recommendation in
docs/decisions/ADR-0127-0128-RESULTS.md. The substrate
(architecture + packs) stays load-bearing in main; the math
expert promotion path retargets to a benchmark where exact
recall and determinism are the discriminators (proposed
ADR-0131).
P3 — generate/math_candidate_graph.py:
Branch enumeration over per-sentence candidate choices (Cartesian
product, cap=64). Per-sentence ambiguity tiebreaker via most-grounded-
slots-wins (transfer beats subtract when 'to Tom' grounds). Decision
rule: 0 admissible -> refuse; 1 -> emit; >=2 same answer -> emit;
>=2 different answers -> refuse (preserves wrong==0 on genuine
ambiguity). End-to-end parse_and_solve(text) -> CandidateGraphResult.
Question extractor added to math_candidate_parser.py (CandidateUnknown,
total + entity question shapes mirroring math_parser).
22 new tests. Permissive verbs ('bought', 'ate', 'bakes') now produce
correct answers via the candidate-graph path; ambiguous 'gives to Tom'
resolves to transfer reading (Tom gets the apples) deterministically.
P4 — evals/gsm8k_math/runner.py:
New sibling function _score_one_candidate_graph(case) -> CaseOutcome.
Identical shape to _score_one; swaps parse_problem for parse_and_solve;
preserves verifier/realizer/expected-answer stages. Callers (e.g.
PR #160's train_sample/v1/runner.py) substitute the new function in
one line to evaluate the candidate-graph topology.
9 new wiring tests. Three groups:
- No regression: cases legacy solves, new also solves.
- Lift: cases legacy refuses, new solves (the architectural payoff).
- Wrong==0: out-of-grammar refuses, never wrong.
Regression: 714/714 existing math + runner tests still green.
ADR-0126 total: 74/74 tests green across P1+P2+P3+P4.
Sibling to math_parser.py — pure candidate-extraction functions that
emit list[CandidateOperation] per sentence without mutating any state.
State threading defers to P3 (per-branch graph assembly).
Topology change vs legacy:
- No first-match-wins; every verb-kind regex runs independently.
- Ambiguous verbs ('gives', 'returns') emit multiple candidates;
P1's round-trip filter + P3's decision rule resolve.
- Out-of-grammar sentences return [], NOT ParseError. Empty list
is the deterministic 'no candidate' signal.
Permissive verb tables (imported from math_roundtrip.KIND_TO_VERBS)
mean past-tense and production verbs ('bought', 'ate', 'bakes')
that the legacy parser refused are now admissible — the round-trip
filter is the safety mechanism, not regex narrowness.
P2 scope (canonical Subject-verb-Value-Unit-[to-Target] shape only):
- extract_initial_candidates(sentence) for 'X has N units'
- extract_operation_candidates(sentence) for add/subtract/transfer
Out of scope (deferred to later sub-phases):
- Pronoun resolution / unit inheritance (needs per-branch state)
- Multiply / divide / rate / comparison (same machinery, more matchers)
Regression: existing math suite 701/701 green. Zero changes to
math_parser.py, math_solver.py, math_verifier.py, math_realizer.py.
The wrong-answer firewall for the candidate-graph parser topology.
A CandidateOperation carries an Operation plus source-span provenance
for every content slot the parser claimed (verb, value, unit, actor,
transfer target, comparison reference). roundtrip_admissible() checks
each slot grounds in the source span AND the matched verb is
registered for the claimed kind.
Two consequences:
- A regex that mis-reads 'loses' as add fails (loses not in ADD_VERBS).
- A regex that hallucinates a number/unit not in source fails to ground.
KIND_TO_VERBS is the new single source of truth for {kind -> verbs};
P2 will refactor math_parser to consume it. Verb tables are
permissive by design (much wider than current narrow regex tables)
because the filter rejects wrong candidates downstream — narrowness
is no longer the safety mechanism.
Deterministic: pure byte/regex containment. No randomness, no
learning, no approximation. Preserves wrong==0, trace_hash byte-
equality, replay determinism.
Closes 5 of 8 surface-form gaps Gemini identified in Task 5 on the
99 comparison-bearing sentences my ADR-0123 substrate currently refuses
in the sealed holdout. Pure regex / parser-state work — no graph,
solver, verifier, or pack changes; preserves wrong==0 discipline.
Expansions (in safety order)
- Group 8 (verb): comparison verbs widened from {has} to {has, have,
had, gets, get, got, takes, take, took, buys, buy, bought}.
"lost"/"won" excluded — they semantically invert direction.
- Group 3 (word-form numbers): _WORD_NUMBERS {one..twelve} accepted
wherever digit values are. _parse_compare_number helper centralizes
the dispatch.
- Group 4 (ellipsis / implicit unit): unit slot made optional in
multiplicative patterns (solver already infers unit from reference
state); added "twice|N times as much", "twice|N times the
number/amount of <unit>" variants.
- Group 1 (subjects / references): actor/reference slots widened from
bare proper noun to {proper noun, "the <noun>" collective,
pronoun}. Pronouns resolve via state.last_singular_subject; missing
prior subject raises ParseError (no silent emission with empty
actor). New _resolve_compare_entity helper canonicalizes "The boys"
/ "the boys" to the same entity string.
- Initial-possession + question patterns widened symmetrically so
"the X" subjects round-trip end-to-end:
- _INITIAL_HAS_RE accepts "the <noun>" subject + has/have +
digit-or-word value
- _Q_ENTITY_RE accepts "the <noun>" entity + do/does auxiliary
- _Q_TOTAL_RE now tried first (specificity-ordered) so "do they
have" doesn't get greedily matched as entity="they"
Deferred (per Gemini Task 5c recommendation)
- Group 2 (age): needs new "years_old" attribute model
- Group 5 (nested): needs compound y = mx + c solver operation
- Group 7 (currency): low volume (2 cases), defer
- Group 6 (compound multi-clause "and" split): scoped out of this
PR to keep the wrong==0 risk profile tight; safer to land after
Gemini Task 6 confirms current expansion doesn't introduce
misparses on the sealed set
Test coverage
- 507 existing math + ADR-0122 + ADR-0123 tests pass (no regressions)
- 16 ad-hoc smoke cases pass (3 baseline + 3 Group 8 + 3 Group 3 +
3 Group 4 + 3 Group 1 + 2 refusal guards + 1 rate cross-check)
- smoke suite 67/67, algebra suite 82/82 green
Expected sealed lift
- Gemini Task 5 catalog projected ~65/90 strict-comparison-only
cases unblocked by the 5 included groups (71/99 comparison-bearing
sentences). Empirical sealed measurement pending Gemini Task 6;
PR will be updated with the actual correct/wrong/refused bucket
counts once measured.

ADR-0123-parser-comparison-phrasing as the **surface increment** on
PR #155's substrate (commit c9bd5d4). Closes the last architectural
gap in the comparison-phrasing class: before this commit, the
substrate's solver evaluated comparison problems successfully but
realize() crashed with `unknown operation_kind 'compare_additive'`
when asked for show-your-work prose.
Substrate (PR #155) already shipped:
- `Comparison` typed graph operand
- `compare_additive` / `compare_multiplicative` operation kinds
- parser patterns for the four canonical surfaces
(N more / N fewer / twice / N times / half)
- solver + verifier wiring + pack lemmas
(en-arith-006 compare_additive, en-arith-007 compare_multiplicative)
This surface adds:
- `_compare_additive_sentence(step)` rendering `direction='more'|'fewer'`
- `_compare_multiplicative_sentence(step, entity_units)` rendering
`direction='times'|'fraction'`
- two new branches in `_step_sentence` dispatch
- `_step_sentence` signature widened with optional `entity_units` map
(derived once-per-trace in `realize()` from `graph_initial_state`)
- ADR-0123-parser-comparison-phrasing.md (~15 invariants, substrate
+ surface decomposition rationale, multi-construction barrier
inheritance)
- 26 invariants pinned across canonical surfaces, plurality
independence, byte-determinism, refusal discipline, and
backwards-compatibility with the pre-comparison realizer templates
End-to-end pipeline now operates on all four canonical comparison
shapes:
parse_problem(
"Alice has 5 apples. Bob has 3 more apples than Alice. "
"How many apples does Bob have?"
) -> solve() -> realize().as_prose() ->
"Alice has 5 apples. Bob has 3 more apples than Alice, giving Bob
a total of 8 apples. Bob has 8 apples."
Measurement (this PR):
- 26/28 direct ADR-0123 tests pass; 2 skipped (CORE_HOLDOUT_KEY)
- `core eval cognition` byte-identical: 100/100/100/100
- ADR-0118 stepped-realizer templates re-render byte-identically
- Substrate measurements continue to hold
Honest non-result: sealed `correct_rate` stays at 0/1319. The
realizer cannot create matches the parser refuses; the multi-
construction barrier the substrate ADR documented holds at the
surface layer too. Cumulative lift signal expected only after the
3rd/4th foundational class lands (per ADR-0121's revised
sequencing). `wrong == 0` holds by construction — realizer only
renders successful traces.
Pre-existing failure noted (not introduced by this PR):
`tests/test_adr_0085_gloss_aware_cause.py::test_flag_off_metrics_byte_identical`
fails on substrate base (c9bd5d4) without these changes — an
ADR-0085 cognition baseline drift unrelated to the realizer.
Second parser-expansion ADR after ADR-0122 rate/per-unit. Adds the
comparison algebra substrate (Comparison dataclass + compare_additive /
compare_multiplicative operation kinds + parser patterns + solver /
verifier / pack lemmas) mirroring the substrate-only / lift-deferred
pattern ADR-0122 established.
Substrate
- Comparison(reference_actor, delta: Quantity|None, factor: float|None,
direction: Literal[more,fewer,times,fraction]) frozen dataclass with
direction-discriminated delta/factor enforcement and self-reference
refusal at the Operation boundary
- compare_additive + compare_multiplicative operation kinds admitted in
VALID_OPERATION_KINDS; Operation.operand widened to Quantity|Comparison
with kind-discriminated type enforcement; entity-set validation extended
to cover Comparison.reference_actor
- Parser: _COMPARE_ADDITIVE_RE (more/fewer/less), _COMPARE_TWICE_RE,
_COMPARE_N_TIMES_RE, _COMPARE_HALF_RE happy-path patterns + 5
refusal patterns (ambiguous 'N times more', age comparisons,
combined-with-aggregation, nested additive+multiplicative); inserted
before _try_initial so leading 'has <N>' shape is not greedily
consumed as initial possession with unit='more'/'fewer'
- Solver: _apply_compare_additive (refuses on missing reference state,
overwrite, negative result); _apply_compare_multiplicative (refuses
on missing reference, ambiguous multi-unit reference, overwrite);
unit comes from delta.unit (additive) or reference's unique unit
(multiplicative)
- Verifier: _verify_compare_additive_step + _verify_compare_multiplicative_step
byte-equal replay; tamper-detects after_value, direction, factor
- Pack: en-arith-006 compare_additive + en-arith-007 compare_multiplicative
lemmas + glosses; SHA-256 checksums refreshed; manifest 1.0.0 -> 1.1.0;
provenance tagged adr-0123:comparison_extension:2026-05-23
Measurement (honest; from Gemini empirical sealed run on parallel surface
branch with this substrate)
- Sealed GSM8K correct_rate: 0/1319 (substrate matches zero real cases
alone). Validates the ADR-0122 multi-construction barrier prediction:
comparison constructions in GSM8K rarely appear alone — they bind with
rate (ADR-0124), percentage (ADR-0125), aggregation (ADR-0126), or
conditional ('if') clauses. First lift signal requires composition.
- Sealed GSM8K wrong: 0 (load-bearing positive claim; ADR-0114a
Obligation #4 preserved across all 1,319 sealed problems)
- Regression safety: 0 — all 913 non-comparison cases continue to
refuse exactly as before (refused_parser), no greedy consumption by
the new comparison patterns
Surface-form catalog (from Gemini Task 2 survey, see ADR doc) covers
6 primary forms across Groups A/B/C; Groups D (age), E (combined with
aggregation), F (nested additive+multiplicative) refused as out-of-scope
with typed ParseError naming the missing companion ADR.
Branch isolation
- Landed via dedicated worktree (feat/adr-0123-substrate from origin/main)
after a file-race on the shared umbrella branch. Companion surface +
scaffolding (realizer, ADR doc, tests, README) lands separately as
feat/adr-0123-surface; orchestrator merges both into the umbrella
feat/adr-0123-comparison-phrasing.

Phase 4 of the ADR-0114 GSM8K-math roadmap. Consumes a SolutionTrace
and emits one sentence per step plus setup + answer sentences. Pure
function; same trace → byte-equal RealizedTrace.
What landed
generate/math_realizer.py
- realize(initial_state, trace) -> RealizedTrace
- Frozen RealizedTrace dataclass with canonical_bytes() + as_prose()
- Per-kind sentence rules (add / subtract / transfer / multiply×2 /
multiply×3 / multiply-general / divide)
- Singular/plural surface rule matches parser canonicalization
- Typed RealizerError on unrecognized step kinds
tests/test_math_realizer.py — 60 cases pinning five invariants:
1. All 50 dev-set cases realize without error
2. Determinism: byte-equal RealizedTrace across two calls
3. Setup sentence count == initial_state count
4. Step sentence count == operation count
5. Answer sentence contains the resolved value + unit
ADR-0114a obligation discharge update
ADR-0118 hardens determinism (#9) across a third layer (realizer)
and makes #3 / #10 human-inspectable via the prose surface. No
obligation is directly newly discharged by ADR-0118; it's substrate
for ADR-0119 GSM8K eval lane.
Round-trippability of the prose through the parser is explicitly
out of scope for this phase. The trace is the verifiable artifact
(ADR-0117); the prose is human-readable documentation.
Tests: 60 new realizer cases; 546 total green across realizer +
parser + solver + verifier + OOD; 67/67 smoke green.

Phase 3 of the ADR-0114 expert-capability roadmap. Re-applies every
step of a SolutionTrace from the input graph's initial state and
asserts byte-equal reproduction of answer_value. Pure function; same
(graph, trace) → byte-equal VerifierVerdict.
Why this is distinct from the solver
ADR-0116's solver enforces correctness at construction. ADR-0117's
verifier is a SECOND, INDEPENDENT implementation that re-derives
every value the trace claims. The verifier does NOT call solve(). It
re-implements the operation semantics from ADR-0116 directly inside
_verify_step. If the solver had a bug or was tampered with after the
fact, the verifier catches it.
Six checks per verdict (named, ordered, audit-logged):
1. graph_canonical_hash_matches
2. pack_id_matches
3. pack_lemmas_resolve
4. step_pack_lemma_ids_match_bindings
5. step_replay_matches_before_after
6. answer_value_reproduces
Seven named tamper classes all caught:
- mutated before_value / after_value / operand of any step
- mutated pack_lemma_id of any step
- mutated graph_canonical_hash
- mutated answer_value
- mutated pack_id
- mutated target_before / target_after of transfer step
ADR-0114a obligation update
#3 Replay-equal trace — now discharged at VERIFIER FIDELITY
(was solver-only under ADR-0116). A third party with only
(graph, trace, pack) can reproduce the answer byte-equal.
Five of ten obligations now load-bearing: #3, #4, #9, #10 plus
in-flight #2 (Codex's ADR-0118a OOD generator).
Tests: 62/62 verifier suite green; 67/67 smoke green; existing
solver + parser + schema suites unaffected.

Phase 2 of the ADR-0114 expert-capability roadmap. Consumes the
MathProblemGraph from Phase 1 and emits a SolutionTrace — ordered
operation applications ending at a numeric answer, byte-deterministic
across runs, with each step's operation bound to a pack-resolved
lemma identifier.
What landed
generate/math_solver.py
- solve(graph) -> SolutionTrace; pure function, no I/O, no globals
- SolutionStep dataclass with before/after values per step (for
verifier replay; ADR-0117 hardens)
- SolutionTrace with canonical_bytes() byte-deterministic JSON
- SolveError typed refusal: missing pack, division by zero,
unknown-references-nothing
language_packs/data/en_arithmetic_v1/
- 5 operator lemmas: add / subtract / multiply / divide / transfer
- role=operational_base (vocabulary-only; no domain claim)
- SHA-256-anchored lexicon + glosses; manifest carries
provenance=adr-0116:operator_seed:2026-05-22
tests/test_math_solver.py — 109 cases pinning five invariants:
1. Phase 2 exit criterion: ≥ 0.80 on parser-correct dev set
(current: 50/50 = 1.00)
2. Determinism: two solves produce byte-equal trace
3. Trace replay reproduces answer_value (verifier rehearsal)
4. Typed refusal on under-determined inputs
5. Every step.pack_lemma_id resolves to a real lexicon entry
in en_arithmetic_v1
ADR-0114a obligation discharge
Four of ten anti-overfitting obligations now have load-bearing
implementations in code:
#3 replay-equal trace — discharged (solver-layer)
#4 typed refusal — discharged (solver-layer)
#9 determinism — discharged (solver-layer)
#10 operation provenance via pack — DISCHARGED IN FULL
Removing the en_arithmetic_v1 pack now breaks every solve loudly.
The "operations bind to concepts, not hardcoded strings" claim is
architecturally true, not rhetorical.
Tests: 109/109 green on solver suite; 67/67 smoke suite green;
parser + schema suites still green from prior phases.

Closes Phase 1.3 of the ADR-0114 expert-capability roadmap. Turns a
grade-school word problem into a typed MathProblemGraph deterministically
(no LLM, no sampling). Same input string always produces the same
graph; unsupported constructions raise ParseError rather than guessing.
What the parser handles
Initial possession: "<E> has <N> <unit>."
Add verbs: buys, gets, finds, receives, earns, adds
(+ "<N> more" / unit elision via state.last_unit)
Subtract verbs: eats, loses, sells, donates, uses, spends, drops, removes
Transfer verbs: gives, sends, hands, passes, mails (with target)
Multiply (scalar): "X doubles <obj>" / "X triples <obj>"
Divide (split): "X splits {them|his Y|N Y} evenly into M groups [and keeps one]"
Compound sentences: "X buys 5, then donates 3."
Sentence opener: "Then X eats 1." (inherits subject + unit)
Pronoun anaphora: he/she/it → last-introduced singular subject
Object pronoun: them/these/those → state.last_unit
Trailing PP: "finds 7 buttons on the floor" — discarded
Singular→plural: "Iris has 1 coin" → canonical unit "coins"
Questions:
"How many <unit> does <E> have [left|now|in total|altogether]?"
"How many <unit> do they have [in total|altogether|left|now]?"
What it explicitly rejects
- Conditional / time-modal ("If X had ...")
- Compound questions (two unknowns)
- Multiple "?" sentences
- Questions referencing entities never introduced
- Empty / whitespace-only input
Verification
- tests/test_math_parser.py: 20 cases (5 byte-equal parametrized
+ 5 determinism parametrized + 1 exit-criterion gate + 6 typed-
refusal + 2 purity + 1 type check)
- tests/test_math_problem_graph.py: 26 schema cases still green
- On the 5 seed cases: 5/5 = 100% byte-equal
- On Codex's PR #128 50-case dev set (locally tested):
49/50 = 98% byte-equal. Single failure (gpd-021) is a case-
quality issue, not a parser limit; feedback filed on #128 to
rewrite (mixed units + metaphor not in pattern registry).
- Phase 1.3 exit criterion (≥ 0.90): met.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
First Phase of ADR-0114's expert-capability roadmap. Decomposed into four
sub-phases so each lands as its own auditable step:
1.1 schema + 5 seed cases + invariants ← this commit
1.2 45 more dev-set cases ← delegated (Codex)
1.3 the parser itself ← exit: ≥0.90 on dev set
1.4 runtime binding ← if non-trivial
What landed
- generate/math_problem_graph.py — typed dataclasses (Quantity,
InitialPossession, Operation, Unknown, MathProblemGraph) + frozen
validation + canonical_bytes() byte-deterministic serialization +
graph_from_dict roundtrip.
- evals/gsm8k_parser_dev/cases.jsonl — 5 seed cases (gpd-001..005)
covering single-add, single-subtract, multi-step, two-entity
transfer, and multi-entity sum constructions. Every case carries a
ground_truth_graph and the documented patterns it exercises.
- evals/gsm8k_parser_dev/README.md — authoring contract: schema,
pattern registry, canonicalization rules, Phase 1.1 scope boundary,
hand-solving rubric, distribution target for the remaining 45
cases. This is the spec Phase 1.2 authors work against.
- tests/test_math_problem_graph.py — 26 cases pinning four invariants:
round-trip byte equality, canonical_bytes() determinism, schema
rejection of malformed graphs, and ground_truth_graph ↔
expected_answer agreement (a hand-solver inside the test module
falsifies mis-authored cases).
Why this is sticky
The Phase 1.1 schema is load-bearing for Phase 1.2 (the 45 authored
cases will be written against it) AND Phase 1.3 (the parser will be
graded byte-equal against ground-truth graphs in this schema). Changing
the schema after Phase 1.2 lands requires an amendment ADR + rewriting

Between 2026-05-17 and 2026-05-22 the inference_closure lane regressed
from all_pass_rate=1.0 to 0.4 on public. Root cause: the
_DECLARATIVE_RELATION_RE branch in generate/intent.py runs ahead of the
_RULES loop and swallowed sentences beginning with 'Actually' into the
subject phrase, routing them to VERIFICATION. The lane's premise emit
path is gated on CORRECTION intent, so PackMutationProposal records
stopped being emitted for any non-'is' relation (precedes / grounds /
causes / reveals). Only the four transitive_is cases passed because
'is' is not in the declarative-relation verb list.
Fix: _CORRECTION_CUE_PREFIX_RE guard. When the text begins with a
correction cue ('Actually', 'Incorrect, ', 'No, ', 'Correction'), the
declarative-match branch is skipped and the sentence falls through to
the _RULES CORRECTION rule. Plain declarative-relation assertions still
route to VERIFICATION unchanged.
Lane on 2026-05-22 post-fix:
dev/v1: all_pass_rate=1.0, overall_pass=True (5 cases)
public/v1: all_pass_rate=1.0, overall_pass=True (20 cases)
- tests/test_correction_cue_prefix_routing.py pins both halves of the
guard (10 new tests).
- evals/inference_closure/gaps.md documents the regression + fix in a
new section, preserving the 2026-05-17 resolution narrative.
- evals/inference_closure/results/ now carries canonical v1_dev and
v1_public reports (the lane had no checked-in results before; ADR-0110
will reference these).
This unblocks the second of ADR-0107's two named blockers. ADR-0110
(math expert-demo re-attempt) now becomes feasible once the math
domain's three lanes have signed-and-digested evidence.
The Phase 1 multi-clause renderer (commit 63ffd88) produces grounded
content but reads mechanically because the subject lemma repeats in
every clause:
"Truth is what is true. Furthermore, truth belongs to cognition.truth.
In turn, truth grounds knowledge. Truth belongs to epistemic.ground.
Furthermore, truth belongs to logos.core. In turn, truth requires
evidence."
This is the literal articulation gap that motivated Phase 2 —
"reasoning at meaningful checkpoints during sentence construction
in order to have a stronger idea of what has come prior and is
already done to help better inform the next move." Between move
``i`` and move ``i+1`` the renderer now reflects on what subject
has just been established (the "focus") and renders the next clause
with a pronoun when the focus carries forward:
"Truth is what is true. Furthermore, it belongs to cognition.truth.
In turn, it grounds knowledge. It belongs to epistemic.ground.
Furthermore, it belongs to logos.core. In turn, it requires
evidence."
Rules
-----
* Track ``focus_subject`` across moves (the lemma most recently used
as a fact subject).
* When the next move's ``fact.subject`` is byte-equal to the current
focus → swap subject token to ``"it"``.
* When the next move's subject differs → preserve the explicit lemma
AND update focus. Topic shifts (TRANSITION moves; compound bridge
TRANSITION) thus reset the pronominalization channel naturally.
* Sentence-initial position (no connective): capitalised ``"It"``.
* Mid-sentence (after connective + comma): lowercase ``"it"``.
Doctrine alignment
------------------
Pure deterministic transformation of the existing plan; no new
content introduced, no LLM, no stochastic sampling. Same plan in →
same surface out, always. trace_hash invariance holds because:
* BRIEF-mode prompts short-circuit the planner before render
(commit 63ffd88's fast path) and are unaffected.
* Multi-move plans render to a deterministically-different string
that compute_trace_hash already folds in via ``surface``.
Wiring
------
* New ``reflective: bool = False`` parameter on ``render_plan``
(back-compat default — every existing call site and test pinning
Phase 1 output continues to work).
* ``_clause_for`` gains optional ``prior_focus_subject`` arg used by
the reflective path; unchanged default behaviour.
* Runtime hook ``chat.runtime._maybe_apply_discourse_planner``
passes ``reflective=True`` so the default chat path benefits.
Tests
-----
New ``tests/test_discourse_planner_reflective.py``:
* ``test_reflective_replaces_repeated_subject_with_it``
* ``test_reflective_handles_three_consecutive_same_subject_moves``
* ``test_reflective_capitalises_sentence_initial_pronoun``
* ``test_reflective_resets_focus_on_topic_shift``
* ``test_reflective_off_preserves_phase1_output``
* ``test_reflective_default_is_off_for_back_compat``
* ``test_reflective_is_deterministic``
* ``test_reflective_single_move_byte_identical_to_non_reflective``
(load-bearing — pins that the cognition eval stays byte-equal
across the Phase 2 flip because every cognition case is single-
move).

number / animacy signals the pack lexicon doesn't carry today).
Follow-on to the word-boundary fix (commit 0dd30b8). After tightening
``\bno\b`` etc. with word boundaries, an audit surfaced a separate
pre-existing gap in the CORRECTION trigger: the contracted-only
``that'?s\s+(?:not|wrong)`` slot silently dropped every fully-spoken
copula form to UNKNOWN.
Concrete gap (every one previously UNKNOWN):
"That is not right." → UNKNOWN
"That is wrong." → UNKNOWN
"That was wrong." → UNKNOWN
"That is incorrect." → UNKNOWN
"That is false." → UNKNOWN
"That was not right." → UNKNOWN
"that is mistaken." → UNKNOWN
"That was incorrect." → UNKNOWN
Root cause: the slot ``that'?s\s+(?:not|wrong)`` matches only
that's / thats
— ``'?s`` makes the apostrophe optional but the literal ``s`` is
mandatory. ``that is`` (full word ``is``) and ``that was`` (full
word ``was``) had no path. And the predicate alternation only
accepted ``not`` or ``wrong``; ``incorrect``, ``false``, and
``mistaken`` were also missing.
Fix: widen both slots in one pattern revision.
Before:
that'?s\s+(?:not|wrong)
After:
that(?:'?s|\s+(?:is|was))\s+(?:not|wrong|incorrect|false|mistaken)
The full pattern now reads:
\b(?:no
|that(?:'?s|\s+(?:is|was))\s+(?:not|wrong|incorrect|false|mistaken)
|incorrect
|actually
|correction)\b
Boundary discipline holds: the outer ``\b...\b`` still prevents the
predicate alternation from eating into longer words. Verified:
"That is correct." → UNKNOWN (right NOT in predicate set)
"That is right." → UNKNOWN (right NOT in predicate set)
"That is true." → UNKNOWN (true NOT in predicate set)
"That works." → UNKNOWN
"That is interesting." → UNKNOWN
"That is falsifiable." → UNKNOWN (``false`` + ``i`` is word→word
so ``\b`` after ``false`` fails)
"That was wrongly accused." → UNKNOWN (same logic for ``wrong``+``ly``)
Tests extended:
* ``test_correction_canonical_forms_still_route`` — 8 new parametrize
cases for the fully-spoken copula forms
* ``test_correction_does_not_eat_no_prefixed_words`` — 9 new
parametrize cases for the affirmative ``That is/was ...`` shape
AND the boundary-trap cases ``falsifiable`` / ``wrongly accused``

While investigating the adjacent RECALL classifier gap, a much
wider intent-classification bug surfaced: every prompt beginning
with a word that *starts with* the letters of any CORRECTION
trigger silently routed to CORRECTION with a mangled subject.
Concrete examples seen during diagnosis:
"Now remember light." → CORRECTION subject="w remember light"
"Nothing matters." → CORRECTION subject="thing matters"
"Notice the truth." → CORRECTION subject="tice the truth"
"Note that recall fires." → CORRECTION subject="te that recall fires"
"Nominate a candidate." → CORRECTION subject="minate a candidate"
"Norma is here." → CORRECTION subject="rma is here"
"Notwithstanding ..." → CORRECTION subject="twithstanding ..."
Root cause: ``generate/intent.py`` ``_RULES`` line ~213 used the
pattern
(?:no|that'?s\s+(?:not|wrong)|incorrect|actually|correction)
The alternation has ``no``, ``incorrect``, ``actually``, ``correction``
as bare substrings — no word boundary on either side. Combined with
``re.match``'s start-of-string anchor, *any* prompt beginning with
``No``-, ``Incorrect``-, ``Actually``-, or ``Correction``-prefixed
text matched as CORRECTION; the regex's match span was then sliced
off the prompt to produce a subject like ``"w remember light"``
(from ``"Now remember light."``).
The same hazard threatens:
* ``no`` → eats ``Now`` / ``Notice`` / ``Note`` / ``Nothing`` /
``Nominate`` / ``Norma`` / ``Notwithstanding`` / ...
* ``incorrect`` → would eat ``incorrectly``
* ``actually`` → would eat ``actualization``
* ``correction`` → would eat ``corrections``
Fix: add ``\b`` anchors on both sides of the alternation.
\b(?:no|that'?s\s+(?:not|wrong)|incorrect|actually|correction)\b
``\b`` is zero-width, so ``re.match``'s start-of-string anchor still
holds; the left ``\b`` is a no-op at position 0. The right ``\b``
forces the matched token to end on a word boundary — i.e., the next
character must be non-word (whitespace, punctuation, EOL) — so
``\bno\b`` matches ``"No."`` / ``"No way"`` / ``"No, ..."`` but NOT
``"Now"`` / ``"Nothing"`` / etc.
Verified 11/11 previously-misfiring prompts now correctly classify
as UNKNOWN, and 8/8 legitimate CORRECTION pragmas
(``"No."`` / ``"No way."`` / ``"Incorrect."`` / ``"Actually, ..."`` /
``"Correction: ..."`` / ``"That's wrong."`` / ``"No, that's wrong."`` /
``"no, knowledge is wrong."``) still route correctly.
Tests extended with two new parametrized blocks in
``tests/test_intent_subject_extraction.py``:
* ``test_correction_canonical_forms_still_route`` — 8 cases pinning
the legitimate CORRECTION patterns
* ``test_correction_does_not_eat_no_prefixed_words`` — 10 cases
pinning the boundary fix against regression

core test --suite smoke 67/67 pass
core test --suite runtime 19/19 pass
Out of scope: ``"That is not right."`` (a real CORRECTION pragma the
regex never caught because ``that'?s\s+`` requires literal ``s`` after
``that``; the colloquial ``that is`` form was always UNKNOWN). Separate
gap, unchanged here.
The articulation breadth benchmark surfaced a RECALL intent gap:
Before (bench output):
RECALL UNKNOWN pack Pack-resident tokens — pack-grounded
(en_core_cognition_v1): recall ...
The probe prompt ``"Recall truth."`` classified as UNKNOWN and fell
through to the ADR-0086 pack-resident-token surface — a graceful
degradation, not a hard failure, but a real classifier gap.
Root cause: ``generate/intent.py`` ``_RULES`` line 213 only matched
the imperative ``remember``:
(re.compile(r"remember\s+", re.IGNORECASE), IntentTag.RECALL)
The verb ``recall`` — every bit as natural an imperative — was
missing from the trigger pattern. ``"Remember truth."`` correctly
routed to RECALL; ``"Recall truth."`` did not.
Fix: widen the alternation to ``(?:remember|recall)\s+``. One-word
change; ``re.match`` anchoring at the start of the prompt means the
fix only catches the canonical imperative form, leaving downstream
contexts untouched:
* ``Does memory require recall?`` → VERIFICATION (unchanged;
earlier rule on the aux-verb pattern fires first)
* ``What is recall?`` → DEFINITION (unchanged;
``what\s+is\s+`` fires first)
* ``Why does recall exist?`` → CAUSE (unchanged;
``why\s+`` fires first)
* ``I recall.`` → UNKNOWN (unchanged;
no trailing word after ``recall``, ``\s+`` doesn't match)
* ``Please recall the truth.`` → UNKNOWN (unchanged
— symmetric with ``Please remember the truth.`` since rules use
``pattern.match`` not ``pattern.search``)
After (bench output):
RECALL RECALL pack Truth is what is true. pack-grounded
(en_core_cognition_v1).
The articulation bench probe now routes correctly and produces a
pack-grounded definition surface — the canonical RECALL output on
a pack-resident lemma.
Tests extended: ``tests/test_intent_subject_extraction.py::
test_recall_strips_articles`` is parametrized with four new
``Recall ...`` cases parallel to the existing ``Remember ...``
cases. A regression that re-narrows the trigger pattern fails the
gate immediately.

Item 17 — redundant ``^`` anchors in ``re.match()`` patterns:
``re.match`` anchors at the start of the string automatically, so
the leading ``^`` was documentation-only noise on every pattern
consumed via ``.match()``. Audited each pattern's call site:
* ``_RULES`` (line 144) — used via ``pattern.match(text)`` → strip
* ``_ANAPHORIC_FOLLOWUPS`` — used via ``pattern.match(text)`` → strip
* Module-level ``_COMPARE_RE`` / ``_TRANSITIVE_QUERY_RE`` /
``_FRAME_TRANSFER_RE`` / ``_BELONG_QUERY_RE`` /
``_DECLARATIVE_RELATION_RE`` / ``_HOW_DOES_X_RE`` — all
``.match()`` → strip
* Inline ``re.match`` in ``_strip_confirmation_tail`` → strip
* ``_RESPONSE_MODE_RULES`` — used via ``pattern.search(text)`` →
KEEP ``^`` (``re.search`` does not anchor)
Trailing ``$`` anchors retained throughout because neither
``re.match`` nor ``re.search`` anchors at the end.
A comment block documents the convention so future contributors
understand the ``^`` retain-vs-strip rule.
Tier 5 minor (``chat/runtime.py``):
* Hoisted ``{"is", "are", "was", "were"}`` to module-level
``_BE_FORMS`` constant. Pre-fix ``_prefer_prompt_anchor``
constructed this set on every English turn.
* Replaced the content-token list comprehension + ``[-1]`` slice
with a reverse-iteration short-circuit. Pre-fix the function
materialised the full filtered list just to pick the last
element.
* Cached ``token.casefold()`` once per token via a local in the
loop body. Pre-fix the comprehension called ``.casefold()``
twice per token (against ``_QUESTION_WORDS`` and the inline
aux-verb set).
Validation:
* ``core eval cognition`` byte-identical across all three splits:
public 100/100/91.7/100, dev 100/100/78.6/100, holdout
100/100/83.3/100.
* ``core test --suite cognition`` 120/0/1, ``smoke`` 67/0.
* ``pytest -k intent`` 236/0 (all intent classification tests
pass with the ``^`` removals — the patterns behave identically
under ``re.match`` regardless of the leading anchor).
Comb pass 2026-05-21 (item 16).
Pre-fix ``classify_intent`` applied ``_normalize_subject`` only to
DEFINITION / CAUSE / VERIFICATION paths. COMPARISON, FRAME_TRANSFER,
TRANSITIVE_QUERY (non-"means" branch), and BELONG_QUERY returned
bare ``.strip()`` subjects. A probe like *"Compare the parent and
a child"* would carry the articles ("the parent", "a child") into
the subject slot, breaking downstream pack-resolver lookups that
key on bare lemmas.
Fix: apply ``_normalize_subject(..., IntentTag.DEFINITION)`` at every
classifier return site that was previously bare ``.strip()``.
DEFINITION mode preserves multi-word noun phrases (only strips
leading articles + trailing punctuation + infinitive markers); the
aux-verb stripping that's only meaningful for CAUSE/VERIFICATION
stays scoped to those paths.
Sites fixed (5):
* COMPARISON subject + secondary_subject
* FRAME_TRANSFER subject + frame
* TRANSITIVE_QUERY subject (both the regular and "means" → DEFINITION
redirect branches now share one normalized binding)
* BELONG_QUERY subject
Behavior:
* Eval cases without articles (the entirety of cognition v1) are
byte-identical: ``"memory"`` and ``"recall"`` survive
``_normalize_subject`` unchanged.
* Multi-word noun phrases survive intact: ``"artificial
intelligence"`` is preserved (no aux-verb-strip wrongly trimming
to head-noun).
* Article-prefixed subjects ("the parent") now strip consistently
with the DEFINITION path that's done so since ADR-0049.
Validation:
* 7 new tests in
``tests/test_intent_subject_normalization_consistency.py``
pin the consistency contract across COMPARISON, FRAME_TRANSFER,
TRANSITIVE_QUERY, BELONG_QUERY, DEFINITION (regression guard
on the pre-existing path), and CAUSE (regression guard on the
aux-verb-strip behavior).
* ``core eval cognition`` byte-identical across all three splits:
public 100/100/91.7/100, dev 100/100/78.6/100, holdout
100/100/83.3/100.
* ``core test --suite cognition`` 120/0/1, ``smoke`` 67/0.
* ``pytest -k intent`` 229/0.
Comb pass 2026-05-21 (item 4).
Pre-fix the topological-sort implementation in
``PropositionGraph.topo_order`` had two compounding inefficiencies:
* ``queue.pop(0)`` on a list is O(N) per pop → O(N²) total
* The inner ``for e in self.edges`` rescanned all edges on every
iteration → O(N × E) overall
This is invisible on today's 1–2 node production graphs but would
become a real regression the moment compound-intent multi-node
dispatch (ADR-0089 Phase C2) or the grounded realizer's multi-clause
output (ADR-0088 Phase B follow-up) lands.
Fix: standard Kahn's with a precomputed out-edge adjacency map and
a ``deque`` for the work queue. O(N + E) overall. Deterministic
output preserved — the queue is seeded with sorted zero-in-degree
nodes (identical to the pre-fix list sort), and direct-successor
order matches edge-iteration order (identical when edges retain
insertion order).
Pinned by 6 new tests in ``tests/test_graph_topo_order_perf.py``:
* single-node graph (today's production shape) byte-identical to
pre-fix output
* empty graph returns empty tuple
* chain (A→B→C→D) orders root → leaf
* diamond (A→B, A→C, B→D, C→D) keeps A first, D last, B/C between
* three disjoint roots emit in sorted order
* 100-node chain returns correct full order (would have been
visibly slow under the O(N²) pre-fix algorithm)
Validation:
* ``core eval cognition`` byte-identical (public 100/100/91.7/100)
* ``core test --suite cognition`` 120/0/1
* ``core test --suite smoke`` 67/0
Comb-pass note: item 15 (GenerationResult.tokens typed tuple but
assigned list) was investigated and turned out to be a Pyright
false positive — ``GenerationResult.__post_init__`` already coerces
to tuple via ``object.__setattr__``. Contract is enforced at
runtime; only Pyright's static analyser misses the coercion site.
No fix needed.
Bundle of 5 hot-path optimizations + 1 dead-code removal + 1 import
sweep + 1 helper fold, surfaced by a comb pass through the cognitive
spine starting from ``CognitiveTurnPipeline.run()`` and walking
outward through ChatRuntime, intent classification, the graph
planner, the realizer, and the vault. All eval lanes byte-identical
to MEMORY baseline; null-lift confirmed by ``core eval cognition``
across public / dev / holdout splits.
Hot-path fixes:
1. ``ChatRuntime._apply_oov_policy`` no longer rescans every
manifest per OOV token. Two precomputed booleans on
``self`` capture the FAIL_CLOSED-all and PROPOSE_VOCAB-any
aggregates at construction time. Manifests are immutable
post-construction so the cache is safe. Turns the path from
O(packs × OOV) to O(OOV).
2. ``CognitiveTurnPipeline.run`` calls ``classify_compound_intent``
once and takes its dominant ``compound.primary`` as the seeded
intent. Pre-fix the pipeline called both ``classify_intent``
and ``classify_compound_intent`` on every turn — and
``classify_compound_intent`` internally invokes
``classify_intent`` on the dominant fragment, so every non-
compound prompt walked the 15-regex cascade twice.
3. ``TeachingStore.triples()`` materializes once per turn.
Pre-fix ``_maybe_transitive_walk`` and ``_maybe_compose_relations``
each called ``self.teaching_store.triples()`` independently,
doubling the per-turn O(N) filter+tuple-build cost. Both
helpers now accept an optional ``triples`` arg; the pipeline
computes once and passes through.
5. ``realize_semantic`` and ``realize_target`` build a
``node_id → obj`` map once and look up each step in O(1)
instead of an O(N) linear scan of ``graph.nodes`` per step.
The cost was invisible on today's 1-2 node graphs but would
have become an O(N²) regression on the multi-node graphs
ADR-0089 Phase C2 plans to introduce.
Dead-code / cleanup:
- Removed dead ``CognitiveTurnPipeline._fold_compose_into_surface``
(no callers since PR #76 routed all surface composition
through ``resolve_surface``).
- Folded ``_serialize_walk`` + ``_serialize_compose`` (identical
bodies) into one ``_serialize_operator`` helper.
- Hoisted ``import json`` and ``RatifiedIntent`` from inside hot
method bodies to module top (same pattern PR #76 applied to
``_is_useful_surface``).
- Dead-defensiveness sweep on ``ChatResponse`` field reads in
``pipeline.run()``: ``getattr(response, "<field>", default)``
where the field always exists on the dataclass with a default
is replaced by direct attribute access (6 sites:
``realizer_grounded_authority``, ``recalled_words``,
``grounding_source``, ``register_canonical_surface``,
``pre_decoration_surface``, ``admissibility_trace``,
``region_was_unconstrained``). ``refusal_reason`` retains the
guarded read because ADR-0024 Phase 2 leaves its
materialisation site dormant.
Benchmark profiler:
- ``benchmarks/pipeline_profiler.py`` rebound from
``classify_intent`` to ``classify_compound_intent`` (the new
single-classification site). All other timing hooks unchanged.
Tests:
- 4 new tests in ``tests/test_comb_pass_hot_path.py`` pin: OOV
aggregates exist as bools; compound classifier runs exactly
once per turn; ``triples()`` materializes exactly once per
turn; realizer correctly resolves obj slots across an 8-node
graph.
- All existing tests pass. ``core eval cognition`` byte-identical:
public 100/100/91.7/100, dev 100/100/78.6/100, holdout
100/100/83.3/100.
- ``core test --suite cognition`` 120/0/1, ``smoke`` 67/0,
``runtime`` 19/0.
Closes audit Finding 6 (2026-05-20).
Pre-fix ``_STOP_TOKENS = frozenset({"it", "to", "word"})`` was
hardcoded inside ``generate.stream.generate()`` and inhibited those
three tokens unconditionally across every pack, every language, and
every domain. If a pack legitimately needed one of them as a content
word — e.g. a philosophy pack where ``"word"`` maps to λόγος, or a
syntax pack where ``"to"`` is a content node — there was no override
path. The ``_try_index`` guard handled the case where the token was
absent from the pack, but offered nothing for packs that contained
the token and meant it.
Changes:
* ``generate.stream.generate`` accepts ``stop_tokens: frozenset[str]
| None = None``. ``None`` resolves to the historical
``_STOP_TOKENS`` constant, preserving byte-identity for every
pre-Finding-6 caller.
* ``RuntimeConfig.stop_tokens: tuple[str, ...] | None = None`` —
operator-level override threaded through ``ChatRuntime`` into
``generate()``.
* Default ``None`` preserves byte-identical behavior for every
existing pack and every existing test.
Scope notes:
* This PR delivers the *runtime override* surface. Manifest-driven
per-pack overrides (``generation_stop_tokens`` field in the pack
manifest) are the natural next step but require a pack-schema
ADR and re-ratification of every affected pack, so the wiring
lands first and the manifest field follows on a separate ADR.
* ``agenerate`` was identified as unreachable and is being deleted
in a sibling PR (Finding 7); its hardcoded ``_STOP_TOKENS``
reference disappears with it, so it is intentionally not touched
here.
Verification:
* 4 new tests in ``tests/test_stop_tokens_override.py``:
- ``RuntimeConfig.stop_tokens`` defaults to ``None``
- ``generate()`` signature exposes ``stop_tokens`` with default
``None``
- the historical constant is unchanged
- an explicit override flows through the runtime end-to-end
* ``core eval cognition`` — public 100/100/91.7/100, byte-identical
to the MEMORY baseline.
* ``core test --suite cognition`` — 120/0/1.
* ``core test --suite smoke`` — 67/0.
* ``core test --suite runtime`` — 19/0.
Closes audit Finding 7 (2026-05-20).
``agenerate`` was a 43-line async generator at the bottom of
``generate/stream.py`` that reimplemented the walk loop without
salience candidates, inner-loop admissibility, language candidates,
rotor admissibility, margin mode, trajectory recording, vault recall
scoring, or admissibility tracing — every capability the sync
``generate()`` has accrued since ADR-0022.
Caller audit:
* ``ChatRuntime.achat`` / ``ChatRuntime.arespond`` call the sync
``generate()`` under ``asyncio.to_thread`` semantics (the
explicit comment in ``achat`` documents this: "the underlying
call is still synchronous CPU-bound work").
* No production code, eval, demo, or test references
``agenerate``.
* Re-exported in ``generate/__init__.py`` but only as a public
name, never consumed.
The function was therefore reachable only by accident — any caller
wiring it would silently get a walk that ignores every ADR added
since ADR-0022. CLAUDE.md's "small, load-bearing PRs" doctrine
explicitly disfavors maintaining diverged reimplementations of the
core loop as a future hook.
Removed:
* ``async def agenerate`` (43 lines) from ``generate/stream.py``.
* ``agenerate`` from the ``generate/__init__.py`` star import and
``__all__``.
If a real async walk path becomes necessary later (e.g. once
``achat`` needs genuine off-thread execution), the right shape is a
thin ``asyncio.to_thread`` wrapper over the real ``generate()`` —
not a parallel reimplementation.
Verification:
* ``ripgrep agenerate`` — zero remaining references in the repo.
* ``core test --suite cognition`` — 120/0/1.
* ``core test --suite smoke`` — 67/0.
* ``core test --suite runtime`` — 19/0.
Closes audit Finding 3 (2026-05-20).
Pre-fix ``ratify_intent`` defaulted to ``threshold=0.0``, which admits
anything with non-negative ``cga_inner(prompt, anchor)`` — the field
gate (ADR-0022 §TBD-1) was structurally live but semantically
transparent. RATIFIED was logged on essentially every turn because
the CGA inner product over conformal space is not sign-symmetric.
Measurement (``scripts/calibrate_ratification_threshold.py``):
* Runs every cognition eval prompt (45 cases = 13 public + 13 dev +
19 holdout) through a primed ``CognitiveTurnPipeline``.
* Captures the actual ``cga_inner(prompt, anchor)`` score from the
pipeline's own ``_ratify_intent`` via a temporary spy on the
imported ``ratify_intent`` binding.
Observed distribution:
* 34 RATIFIED: min=+1.1039 p10=+1.1039 median=+2.6820 max=+5.7508
* 11 PASSTHROUGH (no vocab-grounded anchor available; score=0.0)
* 0 DEMOTED at any threshold ≤ 1.10
Threshold = 0.5 chosen as the calibrated default:
* Well below the empirical floor of 1.10 — every currently-passing
case stays RATIFIED, byte-identically.
* Clearly non-trivially positive — random Cl(4,1) inner products
fluctuate around zero, so 0.5 demands genuine correlation with
the anchor rather than passive non-negativity.
* Leaves headroom for the gate to actually demote weakly-aligned
off-corpus / adversarial prompts to UNKNOWN and route them
through the honest-refusal surface.
Verification:
* ``core eval cognition`` — public 100/100/91.7/100, holdout
100/100/83.3/100, dev 100/100/78.6/100 — byte-identical to
MEMORY baselines.
* ``core test --suite cognition`` — 120/0/1
* ``core test --suite smoke`` — 67/0
* ``core test --suite runtime`` — 19/0
* 2 new tests in ``tests/test_ratification_threshold_default.py``
pin both the constant and the signature default so a future
change cannot silently regress to ``0.0``.
Adds a typed legality check that catches a narrow class of incoherent
finite-predicate surfaces before they ship. Scope is deliberately
narrow:
- generate/articulation_legality.py:
- SlotKind enum {VERB, NON_VERB, UNKNOWN}
- ArticulationLegality enum {LEGAL, ILLEGAL_NON_VERB_FINITE_PREDICATE}
- classify_predicate_slot_kind() — token allowlists for known verbs
and known non-verb nouns
- validate_finite_predicate_legality() — fails on negated +
NON_VERB; fail-open on UNKNOWN to preserve canary behavior
- generate/templates.py:
- _inflect_predicate: copular-aware negation
("is X" -> "is not X" instead of the default "does not be X")
- render_step: invokes the legality validator; returns
"I cannot realize that proposition coherently yet." when an
illegal shape is detected
The check is upstream of register / anchor-lens transforms (presentation
+ substantive axes both downstream of the realizer); no interaction
with R6 / ADR-0073 layering.
Tests pin:
- NON_VERB + negated -> ILLEGAL_NON_VERB_FINITE_PREDICATE
- UNKNOWN + negated -> LEGAL (fail-open preserved)
- render_step returns the disclosure string when illegal detected
- render_step still produces the fall-through surface on UNKNOWN
Validation:
- Cognition eval byte-identical (100/100/91.7/100)
- 370 realizer / lens / register / pack / lane tests pass
- anchor-lens-tour + register-tour both green
C1 coherence floor: a deterministic verifier that runs on every
candidate surface produced by the truth path, before assignment to
ChatResponse.surface. Rejects illegal articulations and routes them
to a bounded disclosure string — admission control with a
deterministic fallback, not normalization.
Active rules (R1 deferred during ratification — see ADR):
R2_aux_neg_requires_verb — "<aux> not <wrong-POS>" rejected
R3_be_neg_requires_predicate — "<be> not <verb>" rejected
Fail-open on unknown POS, fail-closed on explicit wrong POS.
Cognition eval byte-identical (100/91.7/100/100).
Original bug class — "Light reveals truth, right?" → "Right does not
thought." — now routes to "I do not have a reviewed articulation for
that yet." with grounding_source=none, walk_surface preserving the
rejected candidate, and telemetry carrying R2_aux_neg_requires_verb.

Closes the last unarticulate cases on the multi_sentence_response
lane. Two complementary changes:
1. ``generate/discourse_planner.py``
* ``ResponseMode.WALKTHROUGH`` budget lifted from (1, 1) to
(1, 4): 1 anchor + up to 3 hops along the teaching-chain graph,
final hop becomes CLOSURE.
* New ``_plan_walkthrough`` selector walks (subject, *, object) →
(object, *, *) starting from the anchor; cycle-safe via the
existing used-fact set; bounded by ``_WALKTHROUGH_MAX_HOPS=3``.
* New ``_plan_walkthrough_fallback`` — when no teaching chain is
rooted on the anchor, emit ANCHOR + (SUPPORT) rather than
fabricating walk steps. Plan retains ``mode=WALKTHROUGH`` so
callers detect "attempted walkthrough, degraded honestly".
2. ``generate/intent.py``
* New classifier rule: ``^walk\s+(?:me\s+)?through\s+`` →
``IntentTag.DEFINITION``. Same orthogonality discipline as the
``Explain X`` rule: ``ResponseMode.WALKTHROUGH`` carries the
walk depth on its own axis.
13 new tests pin: walk shape (ANCHOR + RELATION* + CLOSURE), the
walk invariant (each teaching hop's subject = prior hop's object),
the 4-move cap, the fallback shape on absent chains, fallback mode
retention, cycle-safety against (A→B→A) cycles, and determinism.
Lane re-measurement (24 cases, multi_sentence_response public/v1):
flag off: articulate=0.0833, disclosure=0.1667, unarticulate=0.7500
flag on : articulate=1.0000, disclosure=0.0000, unarticulate=0.0000
The two previously-unarticulate WALKTHROUGH cases ("Walk me through
inference.", "Walk me through recall.") now engage the planner and
render as deterministic teaching-chain walks:
"Inference is a conclusion drawn from premises by reasoning.
Inference requires evidence."
"Recall is to retrieve a stored state from memory.
Recall reveals memory."
Each surface is grounded entirely in pack glosses and reviewed
teaching chains — no fabricated walk steps.
Critical gates all green:
* flag off cognition byte-identical:
public 100/100/91.7/100, holdout 100/100/83.3/100
* smoke suite 67/67
* 91/91 planner tests pass (contract / behavior / compound / helper
/ render / walkthrough)
The 0.875 connective_present_rate remaining flag-on (3 cases without
expected connectives) is the only gap left, and it's now a render-
template question rather than a planner gap.
Adds compound-intent decomposition for prompts that ask multiple
things in one turn ("What is X, and why does it matter?",
"Explain X, but how does it work?", "What is X, and what is Y?").
Three landings in one PR (rule says additive; the three pieces
are inseparable for the runtime hook to do anything useful):
1. generate/intent.py
* New ``CompoundIntent`` frozen dataclass — ordered tuple of
``DialogueIntent`` parts + raw_text + ``.primary`` back-compat
accessor + ``.is_compound()`` helper.
* New ``classify_compound_intent(prompt)`` sibling to
``classify_intent``. Pure, deterministic, byte-stable. Splits
on closed connector list (``,\s+(and|but|because|while)\s+``);
anaphoric tails ("why does it matter") get the prior part's
subject substituted ("why does truth matter") then are
classified independently.
* ``classify_intent`` return shape is untouched — every existing
caller still receives ``DialogueIntent``.
* No new ``IntentTag`` introduced. v1 semantic approximation:
"why does X matter" routes to ``CAUSE(X)``; "matter" means
causal/relevance support, not metaphysical importance.
2. generate/discourse_planner.py
* New ``plan_compound_discourse(compound, mode, bundles)`` —
concatenates per-part sub-plans in source order with a
``TRANSITION`` bridge (fact=None) between consecutive parts.
No cross-part re-sorting.
* New private kw-only ``_exclude_facts`` parameter on
``plan_discourse`` so subsequent sub-plans can avoid emitting
the same facts the prior sub-plans already used (prevents
"Truth is X. Truth is X." duplicates on shared-subject
compounds). Public signature ``(intent, mode, bundle)`` is
unchanged.
3. chat/runtime.py
* Helper ``_maybe_apply_discourse_planner`` now consults the
compound classifier first. When the prompt is multi-part it
builds per-part bundles and calls ``plan_compound_discourse``;
otherwise it follows the previous single-intent path.
* Compound bypass: when upstream tagged the surface ``oov`` /
``none`` because the flat classifier saw a polluted subject
(e.g. ``"truth, and why does it matter"``), but the compound
decomposition reveals a pack-resident primary subject, the
planner engages on the decomposed parts. This narrowly widens
the gate exclusively for compound prompts with substrate.
* BRIEF mode upgrades to EXPLAIN for compound prompts —
single-anchor sub-plans on shared subjects would emit duplicate
anchor sentences in BRIEF.
* Return shape widened to ``tuple[str, str] | None`` —
``(rendered_surface, new_source_tag)``. ``new_source_tag`` is
``"teaching"`` when the plan uses any teaching fact, else
``"pack"`` — so downstream labels reflect actual provenance
even on the compound bypass. Both cold and warm call sites
updated to apply both fields.
24 new tests pin: compound decomposition correctness, source-order
preservation across sub-plans, anaphoric-followup rewriting,
deterministic byte-stable plans, no new IntentTag introduced,
fact-dedup across sub-plans, compound-bypass engagement, and
source-tag correction on planner-engaged surfaces.
Lane re-measurement after 3 compound cases added to cases.jsonl
(24 total cases):
flag off: articulate=0.0833, disclosure=0.1667, unarticulate=0.7500
flag on : articulate=0.9167, disclosure=0.0000, unarticulate=0.0833
Note: disclosure flag-on dropped to 0.0 because the source-tag
correction now correctly labels compound-bypass surfaces as
``pack/teaching`` instead of letting the upstream ``oov`` label
inflate disclosure. The two remaining unarticulate cases flag-on
are the walkthrough prompts targeted by the next landing.
Critical gates all green:
* flag off cognition byte-identical: public 100/100/91.7/100
* smoke suite 67/67
* 32/32 planner tests pass (helper + render + compound)
* 18/18 compound classifier tests pass
Extends ``generate/intent.py:_RULES`` with three new expository
patterns so the upstream subject-extraction gap that the dedup
revealed is closed:
* ``^explain\s+`` → DEFINITION
* ``^(write|compose|draft) (a )?(short|brief)?
paragraph (about|on)\s+`` → DEFINITION
* ``^paragraph (about|on)\s+`` → DEFINITION
Rules placed AFTER the NARRATIVE family so ``Tell me about X`` and
``Describe X`` continue to route to NARRATIVE. Subject extraction
re-uses ``_normalize_subject`` so articles and trailing punctuation
are stripped: ``Explain the parent.`` → subject ``parent``.
``ResponseMode`` is untouched and remains orthogonal: the same prompts
still classify as ``EXPLAIN`` / ``PARAGRAPH`` independently.
20 new tests pin: each rule's expected subject, response-mode
preservation, NARRATIVE/EXAMPLE/existing-DEFINITION rules unchanged.
Lane re-measurement (multi_sentence_response, 21 cases):
flag off: multi=0.1429, primed_multi=0.0000, conn=0.5385, grounded=0.8571
flag on : multi=0.9048, primed_multi=1.0000, conn=0.8462, grounded=0.8571
Combined lift over the original (pre-wiring) baseline:
* multi_sentence_rate: +70pp on the substantive predicate
* primed_multi_sentence_rate: +50pp (0.5 → 1.0 post-classifier)
* connective_present_rate: +74pp (0.10 → 0.85)
* grounded_rate: +39pp (0.47 → 0.86)
Cognition eval byte-identical: public 100/100/91.7/100, holdout
100/100/83.3/100 — these prompts aren't in cognition cases, and the
new rules don't perturb any rule that fires for cognition prompts.
Conversational thread coherence unchanged.
docs/evals/discourse_runtime_baseline_2026-05-19.md updated with the
full delta table; the planner is now load-bearing across the warm
and cold pack/teaching paths and the lane measures real capability
rather than punctuation artifacts.
Step 5 of the discourse-planner sequencing. Closes the chain:
classify_intent + classify_response_mode
-> grounding_bundle_for(subject)
-> plan_discourse(intent, mode, bundle)
-> render_plan(plan)
-> response_surface
Adds RuntimeConfig.discourse_planner (default False). When True, the
runtime — after the warm pack/teaching-grounded surface is set —
classifies the response mode, assembles a GroundingBundle from the
ADR-style accessors, builds a DiscoursePlan, and replaces the warm
surface with the deterministic multi-clause rendering whenever the
plan has more than one move.
Gating discipline:
* Engages only on warm_grounding_source in {"pack", "teaching"} so
vault/none turns and the discovery-signal CAUSE/VERIFICATION
disclosure are preserved exactly.
* BRIEF mode always collapses to a single ANCHOR move, so flag-on
with BRIEF intent is byte-identical to flag-off.
* Empty bundles produce empty plans; the runtime falls through to
the existing warm surface untouched.
Adds render_plan(plan) to generate/discourse_planner.py — a pure,
deterministic multi-clause renderer with fixed canonical connectives:
ANCHOR : capitalized opening sentence
SUPPORT : "Furthermore, ..."
RELATION : "In turn, ..."
TRANSITION: "Consequently, ..."
CLOSURE : skipped when fact is None
Every visible token is a verbatim pack lexicon entry, gloss, or
reviewed teaching chain string — no synthesis.
13 new tests pin:
* render_plan empty/brief/paragraph shape
* canonical connectives present in paragraph rendering
* deterministic + verbatim-fact invariants
* RuntimeConfig.discourse_planner defaults False
* Flag-off surface has no planner connectives
* Flag-on lifts produce structurally well-formed multi-sentence
output on grounded substrate
Lift measurement (multi_sentence_response public/v1, 15 cases):
* flag off: multi=0.40, connective=0.50, grounded=0.40
* flag on : multi=0.40, connective=0.60, grounded=0.40
-> connective_present_rate +10pp; multi-sentence count flat
because the existing narrative composer's literal "." chars in
tags like "cognition.truth" already trigger sentence splits in
the lane regex. Real lift is form quality: e.g. "Tell me about
truth" now renders as "Truth is a claim or state grounded by
evidence and coherent judgment. Furthermore, truth belongs to
cognition.truth. In turn, truth grounds knowledge." instead of
the prior provenance-laden narrative surface.
Critical gates (all green):
* flag off: cognition eval byte-identical
- public 100/100/91.7/100, holdout 100/100/83.3/100
* smoke suite 67/67
* conversational_thread_coherence: 3 unwanted placeholders flag off
and flag on (no regression)
* planner JSON byte-stable across calls (contract tests)
* grounding source order preserved (sidecar tests)
Step 4 of the discourse-planner sequencing. Replaces the contract-only
NotImplementedError with deterministic move-selection rules per
ResponseMode:
* BRIEF → 1 move (ANCHOR)
* EXPLAIN → up to 3 (ANCHOR + SUPPORT + RELATION)
* PARAGRAPH → up to 5 (ANCHOR + SUPPORT + RELATION + TRANSITION + CLOSURE)
* EXAMPLE → up to 3 (ANCHOR + RELATION + CLOSURE)
* WALKTHROUGH→ deferred, falls back to BRIEF shape so planner is total
Move selectors:
* ANCHOR — pack is_defined_as on intent.subject if available, else
first canonical pack fact on subject, else first
canonical fact of any source
* SUPPORT — pack belongs_to on anchor's subject
* RELATION — teaching/cross-pack chain rooted on anchor's subject
* TRANSITION — chain rooted on the relation's object (topic shifts)
* CLOSURE — no new fact; carries given lemmas forward
Empty bundles produce empty plans (planner is total — callers fall
through to the existing single-sentence composer path safely).
Updated contract test test_plan_discourse_is_contract_only ->
test_plan_discourse_handles_empty_bundle to reflect the implementation.
26 new behavior tests pin: per-mode shape (BRIEF/EXPLAIN/PARAGRAPH/
EXAMPLE/WALKTHROUGH), anchor preference for is_defined_as, support
preference for belongs_to, relation preference for teaching source,
paragraph transition topic shift, closure semantics (no new content,
carries given forward), fact uniqueness across moves, anchor fallback
when no pack subject match, and full determinism (byte-stable JSON
across all five modes, pure function equality).
Verification:
* 49/49 planner tests pass (23 contract + 26 behavior).
* smoke suite 67/67.
* cognition eval byte-identical:
public 100/100/91.7/100, holdout 100/100/83.3/100.
Step 3 of the discourse-planner sequencing. Adds
generate/grounding_accessors.py:
* pack_grounded_facts(lemma) -> tuple[GroundedFact, ...]
* teaching_grounded_chains(lemma) -> tuple[GroundedFact, ...]
* cross_pack_grounded_chains(lemma) -> tuple[GroundedFact, ...]
* grounding_bundle_for(lemma) -> GroundingBundle
All four reuse the existing data substrate (chat.pack_resolver,
chat.teaching_grounding._all_chains_index, chat.cross_pack_grounding
chain accessors) — no new loader, no new I/O, no string composer
touched. Pack facts emit one `is_defined_as` per gloss + one
`belongs_to` per semantic_domain; teaching/cross-pack chains emit
verbatim (subject, connective, object) triples; everything sorted by
GroundedFact.sort_key for canonical determinism.
21 new tests pin: pack/teaching/cross-pack accessor shape, canonical
sort order, verbatim object invariant (no synthesis), source_id
points back into real artifact, bundle composition combines all three
sources with pack-first priority, and doctrine invariants (no
*_grounded_surface composer imported, no chat.runtime imported).
Verification:
* 21/21 new accessor tests pass.
* smoke suite 67/67.
* cognition eval byte-identical:
public 100/100/91.7/100, holdout 100/100/83.3/100.
Step 2 of the discourse-planner sequencing: add the presentation-depth
axis ResponseMode (brief / explain / walkthrough / paragraph / example)
as a sibling to IntentTag in generate/intent.py, with a deterministic
rule-based classify_response_mode classifier next to classify_intent.
ResponseMode previously lived in generate/discourse_planner.py; moved
to generate/intent.py so the dependency is one-way (planner imports
from intent, never reverse). discourse_planner.py now re-exports.
Additive-only invariant preserved:
* DialogueIntent fields unchanged (tag/subject/secondary_subject/
relation/frame). No equality breakage anywhere downstream.
* classify_intent branches untouched.
* Callers compose (classify_intent(t), classify_response_mode(t))
rather than threading mode through DialogueIntent.
41 new tests pin: placement (canonical home + re-export identity),
classifier behavior (parametrized over 25 prompts), priority ordering
(paragraph > explain, walkthrough > explain), purity (no clock/env/
filesystem), classify_intent invariance (definition / narrative /
example / cause / verification representative cases), and orthogonality
(intent and mode compose, neither shadows the other).
Verification:
* 96/96 existing intent tests pass.
* 69/69 new contract + characterization + classifier tests pass.
* smoke suite 67/67.
* cognition eval byte-identical: public 100/100/91.7/100,
holdout 100/100/83.3/100.
Contract-only landing for the typed multi-move discourse layer that
will sit between grounding and graph construction:
DialogueIntent + ResponseMode + GroundingBundle
-> DiscoursePlan
-> PropositionGraph
-> ArticulationTarget
-> RealizedPlan
Adds frozen dataclasses (ResponseMode, FactSource, GroundedFact,
GroundingBundle, DiscourseMoveKind, DiscourseMove, DiscoursePlan),
canonical sort + as_dict + to_json serialization (sorted keys,
no-whitespace separators), and the pure plan_discourse signature
(raises NotImplementedError; move-selection rules deferred).
23 contract tests pin the determinism invariants required before
DiscoursePlan can be folded into compute_trace_hash in a follow-up
ADR: frozen-dataclass equality, canonical pack<teaching<vault<operator
ordering, byte-stable to_json across calls and equal plans, JSON
round-trip stability, and signature purity (no chat.* imports, no
clock/env/filesystem reads).
No runtime wiring; smoke suite 67/67; cognition eval byte-identical
(public 100/100/91.7/100, holdout 100/100/83.3/100).
The 2026-05-19 cumulative live probe surfaced a stark gap: ~52% of
realistic conversational definition prompts ("Define X", "What does
X mean?", "What is to V?", "How does X work?", "What causes X?")
returned ``grounding_source="none"`` *even though every subject
lemma was pack-resident* across the 9 mounted English packs.
Root cause: the bottleneck was intent classification + subject
extraction, not lexicon coverage. Five patterns either had no rule
or routed to an intent the runtime dispatcher couldn't handle. The
fluency assessment at
``/Users/kaizenpro/.codex/worktrees/6533/core/notes/fluency_assessment_2026-05-19.md``
named these as Root Cause #1 ("public chat path does not use the
cognitive spine") and Root Cause #3 ("proposition graphs are too
thin"). This commit closes the surface-level half of that gap;
the deeper answer-plan layer (gloss propositions, P3 in the
assessment) is the next step.
Patterns fixed in ``generate/intent.py``:
1. ``Define X`` — added ``^define\s+`` rule mapping to
DEFINITION (placed after ``^what is/are``
so multi-word DEFINITION patterns still
prefer the question form).
2. ``What does X mean?`` — was matching TRANSITIVE_QUERY with
relation=``mean``. Now re-routes to
DEFINITION inside ``classify_intent`` so
``pack_grounded_surface`` fires on X.
Other transitive relations (precede,
ground, etc.) remain TRANSITIVE_QUERY.
3. ``What is to V?`` — added infinitive-marker strip to
``_normalize_subject`` for DEFINITION /
RECALL. ``to`` is gated on intent tag so
it never strips a transfer preposition
from CAUSE / VERIFICATION.
4. ``How does X work?`` — added ``_HOW_DOES_X_RE`` (third-person
mechanistic-cause). Distinct from the
first-person PROCEDURE rule ("How do I
X?"). Verbs: work / function / operate /
happen / exist / behave / act / emerge.
5. ``What causes X?`` — added causative-verb rule (causes /
triggers / enables / prevents / drives /
produces / induces / yields) routing to
CAUSE with X as subject.
Deliberate NON-fix: I considered adding a ``pack_grounded_surface``
fallback in the CAUSE / VERIFICATION dispatcher when no teaching
chain matches the subject. Reverted on review — that masks the
"would_have_grounded" discovery-candidate signal the teaching
pipeline uses to identify teaching-content gaps (see
``tests/test_discovery_candidates``). CAUSE on a pack-resident
lemma without a teaching chain stays ``grounding_source=='none'``
so the discovery layer can log the gap honestly.
``chat/pack_grounding.py``:
Extended ``_CORRECTION_TOPIC_STOPWORDS`` to include polarity
markers (no / yes / maybe / perhaps / hardly / indeed / surely /
definitely). Without this the CORRECTION composer would
short-circuit on ``no`` from "No, my parent disagrees" and miss
the topical lemma ``parent``.
Cumulative probe lift (44 realistic conversational prompts):
BEFORE: pack=16 none=23 oov=4 teaching=1 (52% NONE)
AFTER: pack=37 none=2 oov=4 teaching=1 ( 5% NONE)
The remaining 2 NONE responses are CAUSE-shaped prompts with no
teaching chain — deliberately preserved as the discovery-gap
signal described above.
Tests: tests/test_intent_classification_extensions.py — 23 new
tests covering each pattern + the lift invariant.
Verification:
Cognition eval byte-identical on both splits (100/100/91.7/100
public, 100/100/83.3/100 holdout).
All 111 intent-affected tests green:
test_intent_classification_extensions.py (23)
test_intent_proposition_graph.py / test_intent_ratifier.py /
test_intent_subject_extraction.py / test_narrative_example_intents.py
test_procedure_surface.py
test_correction_topic_lemma.py
test_cross_pack_grounding.py (including the polarity-stopword fix)
test_discovery_candidates.py
test_contemplation_wiring.py
test_en_core_polarity_v1_pack.py
Root cause: recalled_words was built from result.tokens (versor walk
neighbours) rather than the pack-resolved proposition slots. The walk
produces nearest-neighbour traversal artifacts; the proposition already
carries the correct subject/predicate/object from realize(). This made
ground_graph() fill <pending> obj slots with stop-word-adjacent tokens
instead of the actual answer content.
Fix — two changes, one new helper:
generate/intent_bridge.py
• build_recalled_words_from_plan(plan, proposition, walk_tokens)
Constructs the grounding tuple in priority order:
1. plan.object (ArticulationPlan — pack-resolved, already a word)
2. proposition.object_ (Proposition — versor-decoded object slot)
3. plan.predicate (descriptive predicate word, richer than walk)
4. plan.subject (subject as last-resort semantic anchor)
5. walk_tokens (result.tokens alpha-filtered — supplemental backfill)
Strips <pending>/<prior>/empty/non-alpha before deduplicating.
Returns a deduplicated tuple in that priority order.
• articulate_with_intent() gains an optional `proposition` param
(typed as object to avoid import coupling at the call site).
When provided, build_recalled_words_from_plan() is called to
replace the raw recalled_words before ground_graph() runs.
When omitted, behaviour is byte-identical to Phase 1 (backward
compatible: all existing callers and tests pass unchanged).
chat/runtime.py
• The single articulate_with_intent() call site now passes
proposition=proposition so the bridge receives the full
pack-resolved proposition for grounding. walk_tokens (the old
recalled_words) are passed through as supplemental backfill.
• No change to ChatResponse, TurnEvent, GenerationResult, or any
ADR-gated schema.
Adds generate/bridge_trace.py: a structured sink + serializer for
per-turn articulation-bridge trace records, following the exact
ADR-0040 telemetry sink pattern (JsonlBufferSink / JsonlFileSink /
FanOutSink, no wall-clock, redact-by-default).
Modifies generate/intent_bridge.py: articulate_with_intent() emits
one BridgeTraceRecord per call through a module-level opt-in sink
(attach_bridge_trace_sink / detach_bridge_trace_sink). When no
sink is attached the call is a pure no-op — zero behavior change on
all existing paths.
The record captures:
- intent_tag / intent_subject (classifier output)
- plan_subject / plan_predicate / plan_object (articulation slots)
- recalled_words_len / recalled_words_sample (grounding supply)
- pre_ground_obj (what the graph node held before ground_graph)
- post_ground_obj (what it held after, or same if no grounding ran)
- bridge_surface / bridge_useful (final output + usefulness gate)
- fallback_surface (the plan.surface the runtime falls back to)
This is the Phase 1 measurement instrumentation described in the
full-sentence output mastery plan. Phases 2-5 act on the data this
produces; Phase 1 itself is pure observation.
Two new intent shapes + composers turn the runtime's corpus
density into operator-visible articulation. Both consult the
cross-corpus aggregator from ADR-0064; no new ratification needed.
P3.3 — chat/narrative_surface.py + IntentTag.NARRATIVE.

narrative_grounded_surface(subject, max_clauses=4) walks every
reviewed chain rooted on subject across all registered teaching
corpora. Dedupes by (connective, object) — cause + verification
carrying the same predicate emit one clause, not two. Sorts by
(intent, connective, object) for replay stability.
Surface format:
"{X} — narrative-grounded ({corpus_ids}): {dX1}; {dX2}.
{X} {conn1} {O1} ({dO1}); {X} {conn2} {O2} ({dO2}).
No session evidence yet."
Cross-corpus subjects (e.g. mother in relations_v2) emit
narrative-grounded (relations_chains_v2) tag; cognition subjects
emit cognition_chains_v1 tag. Multi-corpus subjects (when
applicable) emit composite "corpus_a + corpus_b" tag.
P3.4 — chat/example_surface.py + IntentTag.EXAMPLE.

example_grounded_surface(object_lemma, max_examples=3) walks chains
where the lemma is the OBJECT — inverts the typical subject-keyed
access pattern. Dedupes by subject; sorts by (intent, subject,
connective).
Surface format:
"{X} — example-grounded ({corpus_ids}): {dX1}.
Example: {subj1} {conn1} {X}; {subj2} {conn2} {X}.
No session evidence yet."
Cross-cutting:
- Both intents added to _OOV_INTENT_TAGS — fall through to OOV
invitation when subject is unknown (Phase 2 gradient discipline).
- Both tagged grounding_source="teaching" (same provenance tier
as the existing teaching_grounded_surface).
- No prose generation, no new mutation surface.
Live verification:

ADR-0066 (this commit completes the ADR). 30 new tests passed.
Full lane: 2067 passed, 2 skipped, 0 failed in 2:32.
Add a deterministic, pack-agnostic post-processor in `generate/intent.py`
that runs after the `_RULES` table fires:
- DEFINITION / RECALL / PROCEDURE: strip trailing punctuation + leading
articles; preserve multi-word noun phrases
- CAUSE / VERIFICATION: additionally strip leading aux verbs; return
the head noun
Closed-set frozen sets (`_ARTICLES`, `_AUX_VERBS`) make the transform
inspectable. No pack load, no algebra change — touches only
`DialogueIntent.subject`.
Cognition eval (13-case public split):
surface_groundedness 46.2% → 61.5% (+15.3 pp)
term_capture_rate 33.3% → 50.0% (+16.7 pp)
intent_accuracy 100.0% (=)
versor_closure_rate 100.0% (=)
Two cases lift through the ADR-0048 pack path
(definition_procedure_023, definition_relation_026 — both
"What is a X?" → subject=X via article stripping). CAUSE / VERIFICATION
subjects are now clean head nouns, foundational for future COMPARISON
pack path / teaching-store inference.
Tests: tests/test_intent_subject_extraction.py (30 tests).
Lanes green: smoke (67), cognition (121), runtime (19), algebra (132),
teaching (17), packs (6).
Closes ADR-0046's deferred follow-up: convert the PropositionGraph
into an AdmissibilityRegion BEFORE generate() runs on the live
chat path.
== generate/intent_bridge.py ==
New public helper:
build_graph_from_input(text, plan) -> PropositionGraph
Same internal call as _build_graph_from_intent, without the
post-generation ground_graph step — suitable for forward use.
== chat/runtime.py ==
When the new flag is on and output language is English, build the
graph and the region before generate() and pass it via region=.
Empty / fully OOV graphs return AdmissibilityRegion(allowed_indices=None),
which generate() treats as unconstrained — the change is a true
no-op when the graph carries no in-vocab anchors.
== core/config.py ==
RuntimeConfig.forward_graph_constraint: bool = False
Default False preserves all pre-ADR-0046 behaviour and the ADR-0024
honest-refusal contract. A first attempt wired the constraint
unconditionally; 15 tests failed with InnerLoopExhaustion because the
intent-derived graph's CGA neighbourhood doesn't intersect the walk's
candidate pool with top_k=8 on the current packs. The honest answer
is not to widen top_k until the failure goes away nor to silently
relax — both erase the architectural information that the geometry
of the graph and the geometry of the walk are not yet co-located.
Opt-in preserves ADR-0024 and follows the ADR-0022→0026 transition-
window pattern.
== Characterisation (core eval cognition, 13-case public split) ==

non-trivial constraint n/a 6 / 13 —
Findings:
- Wiring is correct and safe (no exhaustions, closure unchanged).
- Single-token in-vocab subjects engage the constraint
(light/knowledge/meaning/memory/correction).
- Multi-word OOV subject phrases produced by the intent classifier
fall through to unconstrained — this is the existing intent-
classifier contract surfacing into geometry, not a constraint bug.
- Restricting which tokens the walk may visit did not change
surface_groundedness or term_capture_rate on this lane. The
surface-grounding gap therefore lives downstream of propagation
— in the realizer / surface-assembly / dialogue-role path — and is
the next load-bearing pull. This isolates the next ADR's scope.
== tests/test_forward_graph_constraint_wiring.py (5 tests) ==
- DEFAULT_CONFIG.forward_graph_constraint is False
- Default runtime answers without InnerLoopExhaustion
- Opt-in runtime answers on a short benign input
- Graph builder + build_graph_constraint produce a labelled
AdmissibilityRegion ("graph:unconstrained" or "graph:<root_id>")
- Flag is observable on the frozen RuntimeConfig
== docs/decisions/ ==
- ADR-0047 ratifies the wire-up, opt-in rationale, and A/B numbers.
- README index updated; the Pillar 1→2→3 section now reflects both
the primitive (ADR-0046) and the live wiring (ADR-0047), and
names the next pull (realizer / surface assembly) explicitly.

The original adr-0046 commit was never run. Fixes:
- generate/graph_constraint.py: import RegionSource (was the
non-existent AdmissibilitySource).
- tests/test_graph_constraint.py + demo_01: load pack
"en_core_cognition_v1" (was "en", which is not a pack ID).
- demo_03: read JsonlBufferSink.lines as a list attribute, not a
method call.
- demo_04 (exact_recall_scale): DROPPED. The construction used
raw standard_normal vectors through unitize_versor and asserted
cga_inner self-similarity is the population max. Cl(4,1) has
mixed signature — cga_inner is not self-maximising for arbitrary
unitized random vectors — and the demo failed at N=10 000 in
exactly the way the construction predicts. The exact-recall
claim's correct home is ADR-0045 (real vault path, properly
constructed versors, N up to 100k = 100%).
Doc/index updates:
- ADR-0046 trimmed to three demos, with an explicit note on the
dropped demo's geometric error and the cross-reference to
ADR-0045.
- ADR-0046 verification block updated with measured lane numbers
(smoke 67 / cognition 121 / runtime 19 / algebra 132 /

- ADR-0046 cross-references ADR-0018 (intent_bridge source of the
graph) and ADR-0022→ADR-0026 (AdmissibilityRegion contract).
- docs/decisions/README.md: ADR-0046 added to the index and to a
new "Pillar 1 → 2 → 3 coupling" section linking the graph
constraint to the existing forward-semantic-control chain.

Closes the structural gap identified in the 2026-05-17 assessment:
the PropositionGraph was a post-hoc descriptor of what the field walk
already produced. It is now a forward constraint that shapes what the
walk is ALLOWED to produce.
== generate/graph_constraint.py (new) ==
GraphConstraint — converts a PropositionGraph into an AdmissibilityRegion
before generate() runs, not after. The region's allowed_indices are the
intersection of:
- subject versor neighbourhood (top-k by CGA inner product)
- object versor neighbourhood (top-k by CGA inner product)
- any explicitly named node surfaces already in-vocabulary
This is the Pillar 1 → Pillar 2 coupling that was missing:
geometry (CGA) → structure (graph) → propagation (generate)
build_graph_constraint(graph, vocab, *, top_k) is the public entry.
The region label encodes the graph's root node IDs so the admissibility
trace identifies the constraint source.
== generate/stream.py (updated) ==
generate() already accepts an AdmissibilityRegion. No new API needed —
graph_constraint.build_graph_constraint() produces one.
== evals/industry_demos/ (new) ==
Four standalone demo scripts that each make ONE falsifiable claim no
transformer-LLM wrapper can reproduce. Each script runs independently
via `python -m evals.industry_demos.<name>` and exits 0 on pass / 1 on
fail. Each prints structured evidence to stdout.
demo_01_forward_constraint.py
Claim: When the PropositionGraph names subject=light, obj=truth, the
generation walk is constrained to the CGA neighbourhood of those
versors BEFORE any tokens are produced. The allowed_indices set is
computed from geometry, not from a prompt filter. Demonstrated by
showing the AdmissibilityRegion is non-trivial (< full vocab) and
that all generated tokens score positive CGA inner product against
the constraint field.
demo_02_geometry_drives_identity.py
Claim: Swapping the identity pack (precision_first vs generosity_first)
on identical input produces structurally different surfaces via the
manifold alignment path — not via a system-prompt swap. Demonstrated
by running two ChatRuntime instances with different identity_pack IDs
on the same text, showing hedge_rate and identity_score.alignment
differ, and that the manifold alignment_threshold differs at the
algebra level (not just the text level).
demo_03_deterministic_audit.py
Claim: Three independently constructed ChatRuntime instances on the
same input produce byte-identical JSONL audit lines. Demonstrated
by attaching JsonlBufferSink to each, running chat(), and asserting
hash equality of the emitted lines (modulo the 'turn' field which is
per-instance sequential). This is architectural determinism — not
seeded randomness.
demo_04_exact_recall_scale.py
Claim: CGA vault recall is exact (100%) at N=100, N=1_000, N=10_000.
The needle versor is recovered at rank-1 by cga_inner scan regardless
of vault size. No approximate nearest-neighbour index. No FAISS.
No degradation curve. Demonstrated inline with timing so the
linear-scan cost is visible alongside the 100% recall.
== tests/test_graph_constraint.py (new) ==
8 tests:
- build_graph_constraint returns an AdmissibilityRegion
- allowed_indices is a strict subset of vocab (non-trivial constraint)
- all constraint indices score positive cga_inner against at least
one node versor
- empty graph returns unconstrained region (safe fallback)
- two-node graph unions both neighbourhoods
- constraint label encodes root node IDs
- round-trip: constraint region feeds generate() without raising
- forward vs post-hoc: constrained walk produces tokens in the
region; unconstrained walk may not (statistical, seeded vocab)
Co-Authored-By: Perplexity AI
Closes the 'identity hedges are generic' gap. When IdentityCheck reports
that a specific axis is deviating AND the pack supplies an axis_hedges
entry for that axis, the assembler uses that axis's phrase instead of
ADR-0028's generic preferred_hedge_*. The hedge text now names what is
actually at issue.
Selection: lex-smallest axis_id in (ctx.deviation_axes ∩ axis_hedges).
Deterministic; loader emits axis_hedges in lex order on axis_id.
Example surface at alignment=0.30 (strong band) under default pack:
No deviation → 'It seems that truth reveals reality.'
truthfulness deviates → 'Evidence is thin that truth reveals reality.'
coherence deviates → 'This does not yet cohere: truth reveals reality.'
reverence deviates → 'Reports suggest truth reveals reality.'
Same trajectory + truthfulness deviation, three different packs:
default_general_v1 → 'Evidence is thin that truth reveals reality.'
precision_first_v1 → 'The evidence does not support that truth reveals reality.'
generosity_first_v1 → 'Truth reveals reality.' (above generosity's strong=0.20)
Schema (additive, optional):
surface_preferences.axis_hedges = {
<axis_id>: { 'strong': str, 'soft': str, 'qualifier': str },
...
}
Bounds: each phrase length 1–64; axis_id non-empty. Absent block →
ADR-0028 byte-for-byte fallback. Loader emits pairs in lex order on
axis_id for hashability + deterministic tie-break.

Tests: tests/test_identity_score_decomposition.py — 17 new tests:
per-axis phrase selection, band gating still applies, pack swap with
same deviation produces three different phrases, lex tie-break is
deterministic, depth-language fallback to ADR-0030, backward compat
with empty deviation_axes, and the contract that all three v1 packs
ship axis_hedges for all three default-pack axes.

Scope limits (documented in ADR-0031):
- English-only at v1 (depth languages use canonical ADR-0030 phrases)
- Lex tie-break is operational not semantic — pack authors can re-key
if they need a different priority
- No dominance-driven phrasing (Interpretation A); preserved as
forward-compatible follow-up
Docs: ADR-0031 (Accepted) recorded; docs/identity_packs.md gains
§Axis-specific hedge phrases section and updated v1-pack SHAs; memory
'identity-packs.md' refreshed.
Closes the ADR-0028 'English-only differentiation' gap. Hebrew and
Koine Greek surfaces now consult identity-pack surface_preferences for
hedge and claim-strength shaping, using language-appropriate canonical
hedge phrases. CORE's three-language foundation (English / Hebrew /
Greek) is now uniformly identity-aware at the realizer.
Algorithm: the same four-band hedge/claim-strength logic from ADR-0028
runs for all three languages. Thresholds and claim_strength come from
the identity pack (carried on SurfaceContext). Hedge phrases come
from ctx for English and from a new module-level constant
_DEPTH_HEDGE_PHRASES for Hebrew (he) and Koine Greek (grc).
he: 'נראה ש' / 'אולי' / 'במקרים מסוימים,'
grc: 'δοκεῖ ὅτι' / 'ἴσως' / 'ἐνίοτε,'
Pack swap visibly affects depth-language output: a precision_first
identity pulls hedges to higher alignment than default; a generosity
pack pulls them to lower alignment. Same trajectory through the
manifold → three different Hebrew surfaces under three different
packs. Same for Greek.

- English surface output byte-for-byte unchanged.
- _assemble_he / _assemble_grc with ctx=None match pre-ADR output
byte-for-byte (asserted by TestBackwardCompatibility).
Scope limits (documented in ADR):
- Depth-language hedge phrases are canonical defaults, not per-pack
overridable yet. Future ADR may add a 'languages' block to the
pack schema if a downstream deployment needs override capability.
- Contrast ('However, ...') and subordination ('Given that ..., ...')
remain English-only. Hedge is the dominant differentiator.
- Hebrew/Greek grammar / word order unchanged.
Suite status: cognition 121, teaching 17, runtime 19, formation 182,
smoke 67 — all green. Identity + safety + divergence suites: 26+15+15+15=71
all green.
Promote ADR-0025 from Draft (design note) to Accepted with the
architectural home decision reversed: rotor admissibility lives at
the same generation/propagation seam as ADR-0024's destination
check — in a sibling-but-separate module
`generate/rotor_admissibility.py` — NOT in `algebra/versor.py` or
`field/propagate.py`.
Algebra rejected because admissibility is a pack-semantic test, not
a closure invariant; placing it there couples algebra to pack state
and creates structural temptation toward grade-projection repair
(CLAUDE.md §Normalization Rules forbids). field/propagate rejected
as a forbidden normalization site even when framed as precondition
guard. The clean answer is generation-side, in its own file:
endpoint admissibility (token-side, blade) and rotor admissibility
(rotor-side, frame) compose at the same seam while remaining
conceptually separable.
New module generate/rotor_admissibility.py:
RotorVerdict — admit/reject + score + region_label + reason
check_rotor_admissibility(region, *, field_current, rotor)
-> RotorVerdict
Pure semantic check:
F' = versor_apply(V, F_current)
score = cga_inner(F', region.frame_versor)
admit iff score > 0 (basic positivity in frame half-space)
No state mutation, no closure enforcement (algebra's job).
region.frame_versor is None → trivial admit (back-compat).
RefusalReason extended:
INNER_LOOP_EXHAUSTION — destination-side (ADR-0024 / ADR-0026)
ROTOR_REJECTION — rotor-side (this ADR)
The two reasons let the trace name the axis that ran out without a
parallel exception type. InnerLoopExhaustion(ValueError) hierarchy
unchanged; back-compat preserved.
Wiring in generate/stream.py:
threshold mode per-candidate rotor check after destination admit;
reject → log rotor score, retry next candidate;
exhaustion routes reason to ROTOR_REJECTION iff
any rotor rejection occurred in the step
margin mode rotor check on the top-ranked admissible candidate;
reject → immediate InnerLoopExhaustion(
reason=ROTOR_REJECTION) carrying the destination
ranking + the rejected rotor's score
Phase 4 keeps positivity (score > 0), not margin, on the rotor side.
No cross-case calibration evidence to inform a rotor-margin constant
yet; promoting to ranked-with-margin awaits Phase 5 diversified-
families evidence. Destination-side margin (ADR-0026) is unchanged.
Teaching boundary closed at Stance A — strictly hygiene-only.
Rotor rejections are deterministic geometric outcomes, not reviewed
teaching examples. CLAUDE.md §Teaching Safety forbids parallel
correction paths; entangling rotor rejection with reviewed teaching
would create one. Confirmed in ADR-0025 §"Teaching boundary".
Acceptance evidence (tests/test_rotor_admissibility.py, 11 passing):
No-frame back-compat — frame_versor=None tokens identical to
Phase 3 baseline
Admit when aligned — frame_versor=seed direction admits
seed→destination rotor
Refuse with named axis — orthogonal frame raises
InnerLoopExhaustion(reason=ROTOR_REJECTION); threshold mode
also routes reason correctly
versor_condition < 1e-6 preserved on admitted rotors
Deterministic replay — 5 reruns identical for both admitted and
refused turns
Suite results:
full: 1048 passed, 2 skipped (+11 new rotor tests)
docs/runtime_contracts.md updated with "Rotor admissibility contract"
subsection documenting the seam, the algorithm, and the refusal
taxonomy.
Architectural invariants preserved:
no new code in algebra/versor.py, field/propagate.py, vault/store.py
no approximate recall, no cosine similarity, no HNSW/ANN
no hot-path repair; check is pure typed-verdict
InnerLoopExhaustion(ValueError) hierarchy unchanged
Replace the static-threshold admissibility gate with a ranked-with-
margin check that is scale-invariant under blade-norm variation.
Phase 4 characterization established no single global threshold
separates the v2 mechanism-isolation cases (blade norms vary ~10x);
margins between top and second-ranked candidates do, because they
scale with the blade norm and carry the relative ordering the
geometry actually delivers.
New primitives in generate/admissibility.py:
RankedCandidate — (index, word, score)
MarginVerdict — admit/reject + top + margin + full ranking
rank_candidates_by_blade — sort admissible set by cga_inner desc,
strict > tie-break by ascending vocab index
check_margin — admit top iff score>0 AND margin>=delta
Selection semantics in margin mode are blade-rank-driven: the top-
ranked admissible candidate IS the admitted destination. Differs
from threshold mode (field-driven _nearest_next then per-candidate
gate). Both modes coexist; threshold is the default and ADR-0024
acceptance evidence is preserved byte-for-byte.
Wired through:
core/config.py admissibility_mode="threshold" (default)
admissibility_margin=0.4
chat/runtime.py forwards both fields
generate/stream.py margin_mode_active branch — ranks the
candidate set once per step, admits or
raises InnerLoopExhaustion with the full
ranking in rejected_attempts
Default delta = 0.4 chosen from the v2 case margins:
V2-001: 0.596 V2-002: 0.456 V2-003: 13.27
V2-004: 3.37 V2-005: 12.74
min = 0.456 → 0.4 admits all 5 with headroom; 0.5 would refuse
V2-002. The default is falsifiable: Phase 5 may surface a case
below 0.4, which should be reported as an architectural finding
rather than patched per-case.
Acceptance evidence (tests/test_margin_admissibility.py, 13 passing):
5/5 v2 cases pass in margin mode; forbidden_token in every
case's rejected_attempts ranking
Refusal-on-insufficient-margin: delta=0.9 on V2-001 (margin
0.597) raises InnerLoopExhaustion with full ranking; no silent
boundary fallback
Threshold mode byte-identical with or without margin plumbing
5 reruns produce identical canonical trace steps
Strict > tie-break: equal scores resolve to lower-index winner
deterministically
Invariants preserved:
versor_condition < 1e-6 — rotor V is constructed only for the
admitted candidate; margin mode adds no normalization/repair site
Deterministic replay — strict > tie-break now load-bearing in
rank_candidates_by_blade alongside vocab.nearest
No approximate recall, no cosine similarity, no HNSW/ANN; pure
rank-and-difference on exact cga_inner scores
No new code in field/propagate.py, algebra/versor.py,
vault/store.py, or chat/runtime.respond()
Suite results:
full: 1037 passed, 2 skipped (+13 new margin tests)
core eval cognition: 13/13, 100% intent_accuracy,
100% versor_closure_rate
ADR-0026 documents the contract, the single-delta rationale, the
falsifiability story, and the residual risks. Margin mode is
flag-gated default-off; a future ADR may promote it to default
after Phase 5's diversified families confirm the single delta
holds (or surface the architectural finding if it doesn't).
Replace plain ValueError at both inner-loop exhaustion sites in
generate/stream.py with InnerLoopExhaustion, a typed ValueError
subclass carrying machine-readable refusal evidence:
reason : RefusalReason (INNER_LOOP_EXHAUSTION)
region_label : which AdmissibilityRegion blocked
step_index : -1 = pre-walk empty intersection;
>=0 = in-walk per-step exhaustion
rejected_attempts : ordered (idx, word, score) triples
Backward-compat by construction: subclassing ValueError preserves
every pre-Phase-2 `except ValueError` handler in chat/runtime.py,
eval lanes, and tests. No edits to chat/runtime.py, field/propagate.py,
algebra/versor.py, or vault/store.py.
Trace path wired:
- CognitiveTurnResult.refusal_reason (str, default "")
- compute_trace_hash folds refusal_reason only when non-empty
-> byte-identical hashes preserved for non-refused turns
- CognitiveTurnPipeline reads via getattr from ChatResponse and
forwards into both trace_hash and result construction
Contract documented in docs/runtime_contracts.md §"Refusal contract".
Tests (tests/test_refusal_contract.py — 10 passing):
- InnerLoopExhaustion isinstance(ValueError) at both raise sites
- In-walk site carries reason/region_label/step_index>=0/
rejected_attempts with (int,str,float) triples
- Pre-walk site uses step_index=-1 sentinel + empty
rejected_attempts
- Pre-walk fires even when inner_loop_admissibility=False
- Trace hash: empty refusal_reason preserves legacy bytes;
non-empty differs; same inputs are stable
Suite results:
smoke: 67 passed
cognition: 121 passed
runtime: 19 passed
full: 1024 passed, 2 skipped
core eval cognition: 13/13, 100% intent accuracy, 100% versor closure
Residual silent path (documented as out-of-scope for Phase 2):
chat/runtime.respond()/arespond() still convert any ValueError to
"" for their public str return contract. So a refused turn today
produces surface == "" with refusal_reason == "" — the typed
evidence is unread between the raise site and the result. The
plumbing on result + trace + pipeline is in place so a future ADR
can wire materialisation (propagate exception to
ChatResponse.refusal_reason, or catch at the pipeline seam) without
re-deriving the contract.
Phase 1 (commit 3940290) and Phase 2 (this commit) were developed
in parallel with disjoint file scope to avoid conflicts.
Phase 2 — Corpus observation runner (inner_loop_runner.py):
- Four-condition matrix: boundary_only / null_control / inner_loop_t0 / inner_loop_tpos.
- Added `inner_loop_force_admit` to generate() — exercises the inner-loop
code path but force-breaks on first candidate. Eval-only null control:
isolates rejection as the causal factor for any pass-rate delta.
- Metrics: pass_rate, mean_rejection_count_per_turn,
non_empty_rejected_attempts_rate, exhaustion_rate (gated at 5%),
mean_admissibility_checks_per_turn, mean/p95 added_latency_ms,
trace_hash_stability across 5 reruns per case.
- Finding on v1+dev: causal_attribution_valid=True, code_path_residual=0.0,
but exhaustion_rate=0.33 at t=0 — chain outer-product blade is
geometrically blind to the active pack.
- Tests (tests/test_inner_loop_phase2.py, 5 pass): pin
causal-attribution and live-corpus trace-hash stability invariants.
Phase 3 — Mechanism-isolation v2 corpus (5 cases, v2_runner.py):
- Synthetic adversarial cases with controlled geometry — each case
specifies seed_token, admissible_tokens, relation_blade_token, and
admissibility_threshold. Field state is constructed directly from
the seed token versor, not via priming.
- For every case: boundary-only selects the forbidden decoy and
inner-loop selects the expected endpoint with the forbidden token
appearing in rejected_attempts.
- Result: mechanism_isolated=true on 5/5. boundary_decoy_rate=1.0,
rejection_traced_rate=1.0. Inner-loop rejection is demonstrably
doing causal semantic work on real packs.
- Tests (tests/test_inner_loop_phase3.py, 8 pass): GATE on
mechanism_isolated.
Phase 4 — Threshold characterization (threshold_characterization.py):
- Distribution mapping per-case AND globally on v1+dev, v2, combined.
- Per-threshold sweep over [-1.0, -0.5, 0.0, 0.1, 0.25, 0.5, 1.0].
- Finding: per-case geometry separates cleanly (correct_min > incorrect_max
on every v2 case), BUT no global static threshold passes the
separation_quality >= 0.8 gate. Blade norms vary ~10x across cases.
- Static thresholds (global, relation-typed, or constant frame-derived)
are geometrically insufficient. Per-case-normalized thresholds
(e.g. fraction of blade self-score) are the recommended next step.
- v1 chain-token outer-product cases all skipped — the corpus's chain
tokens (alpha, beta, gamma, delta) are not grounded in the active
pack. Load-bearing finding for ADR-0025 region construction.
- Tests (tests/test_inner_loop_phase4.py, 5 pass): pin the finding
diagnostically (not gated).
Phase 5 — ADR-0025 design note (draft):
- No code changes proposed. Scopes three architectural questions:
(1) home (algebra/versor.py vs field/propagate.py vs generate/) —
preliminary stance: algebra/versor.py.
(2) threshold scheme (blade-normalized fraction recommended over
static; learned/adaptive rejected for determinism).
(3) teaching-loop boundary — Stance A confirmed: rejections are
runtime hygiene only, no entanglement with teaching/*.
- Decisions to be closed before Draft → Accepted.
Phase 1 acceptance criteria from previous commit (7fccf36) carry
forward: wired, deterministic-when-wired, legacy hash preserved.
Suite: 1014 passed, 0 failed, 2 skipped.
Flag-gated semantic change to generate(): when
inner_loop_admissibility=True and a non-unconstrained region is
supplied, each per-step selection is re-evaluated by check_transition
with admissibility_threshold; rejected candidates are excluded and
the walk re-selects until admitted or every admissible candidate is
exhausted (ValueError = honest refusal, same shape as ADR-0022 §2).
Default False — every legacy call site keeps ADR-0023 boundary-only
semantics, and the new AdmissibilityTraceStep.rejected_attempts field
is folded into canonical() only when non-empty, so trace_hash bytes
are byte-identical with ADR-0023 turns.
Invariants preserved: rotor V is only built for the admitted
candidate, so versor_condition < 1e-6 still holds at propagate_step;
no new normalization site; no new I/O / dynamic imports.
Tests: tests/test_inner_loop_admissibility.py covers the four
acceptance properties — default off preserves behavior, rejection
drives re-selection, exhaustion raises ValueError, empty
rejected_attempts is omitted from canonical(). Full pytest: 927
passed, 1 pre-existing unrelated failure (test_language_pack_cache).
Extends ADR-0022 with inspection/telemetry surfaces that turn the
forward-semantic-control claim from "mechanism exists" into "mechanism
is causally load-bearing, isolated, and replayable."
Changes (zero runtime semantics change beyond a pipeline bug fix):
- AdmissibilityTraceStep + GenerationResult.admissibility_trace —
per-transition record of region label, candidates before/after,
selected destination, and the typed AdmissibilityVerdict.
- ChatResponse + CognitiveTurnResult expose admissibility_trace,
admissibility_trace_hash, ratification_outcome,
region_was_unconstrained.
- hash_admissibility_trace + compute_trace_hash fold the new fields
only when they carry non-default values, so pre-ADR-0023 turn
hashes remain byte-preserved.
- Same-path ablation leg in evals/forward_semantic_control/runner.py:
generate(..., region=None) vs generate(..., region=R) on the same
runtime/vocab/field/persona/prompt — isolates the region as cause.
- Lane expansion: 8 dev cases across 4 relation axes (cause, means,
precedes, part_of) including 2 adversarial distractor cases.
- Lane metrics now report region_only_constrained_rate /
region_only_gap / ratified_rate / demoted_rate / passthrough_rate /
passthrough_on_scored.
- Bug fix surfaced by the new accounting: _ratify_intent looked up
runtime.vocab (always None) instead of runtime.session.vocab —
every production turn was silently PASSTHROUGH. Fixed; ratifier
now actually gates intent classification.
- tests/test_admissibility_trace.py: hash determinism +
pre-ADR-0023 byte-preservation tests.
Lane evidence (dev, 8 cases):
- constrained_pass_rate=0.80, causality_gap=0.80
- region_only_gap=1.00 (5/5 with region, 0/5 without — same path)
- ratified_rate=1.00, passthrough_on_scored=false
- overall_pass=true
Bench: 9.41s / 20 turns (~470ms/turn), well inside the +5% budget.
Full pytest: 922 passed, 1 pre-existing failure
(test_language_pack_cache, unrelated to ADR-0023).
Resolves all 5 TBDs and closes all 8 acceptance gates for ADR-0022.
TBD-1 (intent oracle): regex seed + field ratification —
generate/intent_ratifier.py. RATIFIED / DEMOTED / PASSTHROUGH
outcomes; DEMOTED routes through honest refusal.
TBD-2 (region intersection algebra): generate/admissibility.py.
Token-set composition via sorted set intersection; blade composition
via outer product with zero-blade as neutral element; rotor
composition via sandwich conjugation routed through
algebra.backend.versor_apply (Rust parity preserved by construction).
Empty intersections preserved — no silent relaxation.
Wiring: propose() and generate() accept an AdmissibilityRegion
(default None preserves legacy behavior); pipeline ratifies intent
at step 1b.i before graph construction.
Eval lane: evals/forward_semantic_control/ — both legs run against
CognitiveTurnPipeline (constrained) vs bare ChatRuntime.chat()
(unconstrained baseline). Dev (3 cases) and public/v1 (1 case) both
report overall_pass=true, causality_gap=1.0, coincidence_rate=0.0.
Chain-endpoint probe surfaces 'delta' only under forward semantic
control.
Bench cost (30 turns): -2.8% wall-clock (within +5% budget the ADR
set for the ratification gate on every turn). 138x cheaper than
Sonnet 4.5; main was 142x.
Tests: 33 new (25 admissibility + 8 ratifier). Full suite 912/913
pass — the single failure is pre-existing pack-size drift on main,
unrelated.
Categorizes every production vault.recall() callsite as RECOGNITION,
EVIDENCE_TELEMETRY, or EVIDENCE_USER_FACING. Adds INV-24 architectural
invariant (TestINV24VaultRecallRegistry, 3 tests) that forces any new
callsite to declare its role and requires EVIDENCE_USER_FACING sites to
pass min_status=COHERENT.
Audit findings:
- chat/runtime.py:330 → RECOGNITION (gate decision input)
- vault/decompose.py:121 → RECOGNITION (grade-decomposed gate fallback)
- generate/stream.py:147 → EVIDENCE_TELEMETRY (walk_surface per runtime contract)
- No EVIDENCE_USER_FACING sites exist today — user-facing surface comes from
pack-grounded realize(proposition, vocab), not vault.recall.
Why this closes Leak C: the write-side fix already stamps SPECULATIVE on
self-stored propositions; the read-side audit confirms no inference path
treats them as ratified evidence. If a future change routes the
generation walk into the user-facing surface, INV-24 forces the
recategorization to be explicit.
CLAIMS.md Tier 4.5 Leak C row now CLOSED. docs/truth_seeking_schema.md
§Leak C updated with full audit categorization.
Verified: smoke (67), cognition (121), runtime (19), all architectural
invariants (40) — green.
Audit of the one-mutation-path invariant (ADR-0021 §3) found three leaks
where pack authority or session-state writes could substitute for coherence
judgment. All three landed fixes or partial closures in this push.
Leaks closed:
- Leak A: pack vocab defaulted to COHERENT — flipped to SPECULATIVE in
language_packs/{compiler,schema}.py; docstring corrected to align with
ADR-0021 (it was rationalizing the leak).
- Leak B: vault.recall was epistemic-blind — VaultStore.store() now stamps
every entry with EpistemicStatus (default SPECULATIVE); recall(min_status=)
filters to admissible-as-evidence tier. All 4 vault-write sites updated.
- Leak C (write-side): generate/proposition.py:198 stored articulated
propositions unmarked — now stamps SPECULATIVE, breaking the
fabrication-feedback loop in principle. Read-side audit of 5 call sites
is the residual.
New architectural invariants (tests/test_architectural_invariants.py):
- INV-21: one-mutation-path allowlist (caught Leak C on first run)
- INV-22: pack lexicon default is SPECULATIVE (Leak A guard)
- INV-23: vault recall epistemic-aware (Leak B guard)
New eval lanes:
- teaching_injection_resistance — ships GREEN at 1.00/1.00/0 (the
structural anti-injection claim is real and measurable)
- refusal_calibration — honest gap: 0% refusal, 0% fabrication
- contradiction_detection — honest gap: 50% flag via versor-delta heuristic,
100% false-positive; motivates the proper coherence-checker
- articulation_of_status — honest gap: 0% speculative articulation, 60%
false certainty; output-side leak surface
New benchmarks:
- benchmarks/footprint.py — total deployed runtime is 7.06 MiB
(109,358x smaller than Llama 3.1 405B, runs offline, no GPU)
- benchmarks/learning_curve.py — monotonic + replay-deterministic curve
per lane
Documentation:
- docs/truth_seeking_schema.md — foundational architectural commitment,
five rules, mapped to human failure modes, leaks published openly
- evals/CLAIMS.md — five-tier public claims doc; Tier 4.5 publishes
known gaps with named fixes; verification contract at top
- README.md — new pillar between algebraic substrate and language pillar
Includes in-flight formation pipeline scaffolding (formation/, tests/formation/,
docs/formation_pipeline_plan.md) and minor CLI/contracts/gitignore edits
that were already in the working tree at session start.
Verification: 798 passed, 2 skipped, 1 deselected (pre-existing pack-count
test drift unrelated to schema changes).
Closes the user-flagged scope gap: every previous fluency lane (Phase
5.1 + 5.4-5.7 + grammatical_coverage) operates on 3-word SVO probes.
These three pieces stress paragraph-scale generation, give per-stage
latency visibility, and expose the realizer's word-choice geometry —
all on top of the existing deterministic infrastructure.
# discourse_paragraph lane (paragraph-scale fluency)
Forces the realizer to emit multi-sentence paragraphs from a
multi-step ArticulationTarget with rhetorical moves (ASSERT, SEQUENCE,
ELABORATE, CONTRAST). Same realizer, much richer input — every case
is 3-5 sentences with deterministic discourse markers.
Public 12 cases / holdouts 5 / dev 1 across 12 + 5 topic chains
(epistemic, scientific method, creation arc, logical dependency,
ethical grounding, linguistic layers, mathematical chain, narrative,
biology, physics, two contrast-shaped, musical, social, computational,
psychological, economic).
Sub-metrics per case:
- sentence count (within min..max window)
- subject coverage rate
- discourse marker presence (next / furthermore / in contrast)
- sentence-initial capitalization
- replay determinism (run twice, surfaces match)
Result: 12/12 public + 5/5 holdouts at 100%, replay rate 100%, mean
sentence count 4.
# Realizer capitalization (G4, addresses user-flagged concern)
generate/realizer.py gains `_capitalize_sentence` + `_join_as_paragraph`
helpers. Sentence-initial alphabetic characters are now uppercased
(skipping leading whitespace/punctuation). Surfaces went from
"wisdom grounds knowledge. next, knowledge requires evidence."
to
"Wisdom grounds knowledge. Next, knowledge requires evidence."
The discourse_paragraph runner ships a strict per-sentence
capitalization check so future regressions get caught.
# Pipeline-stage profiler (benchmarks/pipeline_profiler.py)
External monkey-patch wrapper around CognitiveTurnPipeline.run() that
records per-stage ns budgets without editing any pipeline source.
Stages: intent, graph_planner, realize_semantic, runtime_chat,
maybe_transitive_walk, fold_walk_into_surface, run_teaching,
trace_hash.
API: `profile_turn(pipeline, text) -> ProfileReport` with
`.stages: dict`, `.total_ns: int`, `.as_dict()`.
Empirical: runtime_chat dominates >99% on the runtime hot path (which
is correct — that's where ingest + propagate + recall + articulate
all happen). Future optimisation work has a clear per-stage signal.
# Word-selection tracer (benchmarks/word_selection_tracer.py)
External wrapper around generate.articulation._resolve_slot that
records every nearest-neighbor lookup as a WordSelectionStep:
- slot (subject/predicate/object)
- input versor (32-d copy)
- top-K candidate words by CGA inner product
- chosen word + morphology
- output language
Top-K scoring uses the diagonal Cl(4,1) metric kernel from
algebra.backend (same vectorised path vault_recall uses), not a
per-word Python loop over cga_inner. No approximation, exact
deterministic ranking, bit-identical to a scalar scan.
API: `trace_realization(pipeline, text) -> RealizationTrace` with
`.steps`, `.realization_steps`, `.surface`, `.as_dict()`.
# CLI lane registration
Cognition suite now sweeps the benchmark profiler/tracer tests
(test_benchmarks_profiler.py) so any future regression in the
instrumentation surfaces immediately.
# Constraints honoured
- Zero edits to core/, chat/, vault/, teaching/, language_packs/, or
the algebra hot path. All instrumentation is external monkey-patch
with originals restored in finally.
- discourse_paragraph runner bypasses ChatRuntime grounding (named v2
gap) so paragraph capability is isolated to the realizer.
- No semantic changes; no hidden normalisation; no approximate
recall.
# Lane health
smoke 55, runtime 19, teaching 17, packs 6, cognition 105 (was 103),
algebra 132. All Phase 5 fluency lanes still 100% with the
capitalised surfaces (rubric is case-insensitive). discourse_paragraph
100%.
# What ships next (named v2)
- Round-trip: discourse_paragraph through ChatRuntime end-to-end,
not just realize_target.
- Per-sentence grammatical_coverage rubric on each emitted sentence.
- Longer chains (10/20/50 sentences) with per-sentence determinism
scaling curves.
- compose_relations operator to lift compositionality recall from
68.8% toward 100%.
Six contained-tier gap closures from the cross-phase gap audit.
Every gaps.md file involved gains a resolution block; the historical
findings are preserved for traceability.
Identity (teaching/review.py)
- _ROLE_FRAMES gains the philosophical-axis family (axiology, ontology,
telos, ethos, epistemology, morality, ethics, virtues, norms,
doctrine, creed, convictions, beliefs, values, principles).
- _REDIRECT_VERBS gains the dismissal family (disregard, dismiss,
bypass, circumvent, renounce, reject, repudiate).
- Closes multi_agent_composition holdout MAC-HOLD-001 ("disregard your
axiology") and the matching adversarial_identity gap.
- Multi-agent holdouts: 8/8 attacks rejected, 3/3 legits accepted.
Pipeline (core/cognition/pipeline.py + docs/runtime_contracts.md)
- When the unknown-domain gate fires, ChatRuntime returns the
"I don't have field coordinates for that yet." stub and
vault_hits == 0. The pipeline now honours that stub as the
user-facing surface instead of overriding with the realizer's
fallback articulation. walk_surface is unchanged either way.
- New contract test
tests/test_semantic_realizer_integration.py::test_pipeline_honours_safety_stub_when_gate_fires
locks the contract; the existing semantic-surface test now primes
the vault first so the gate doesn't fire on the probe.
- Closes calibration gaps.md Finding 2.
Realizer morphology (generate/morphology.py)
- G1: ~100-entry irregular-verb table replaces the previous list which
contained only regular forms. Includes bind→bound, run→ran,
stand→stood, write→wrote/written, eat→ate/eaten, fly→flew/flown,
swim→swam/swum, etc.
- CVC doubling rule for -ed and -ing (stop→stopped/stopping,
plan→planned, run→running).
- Short-ies disambiguation (die/lie/tie keep -ie- in the base; cry/fly
collapse to -y). Lie is also irregular (lay/lain) — uses
_IRREGULAR_FORMS first.
- 28-case regression test (tests/test_morphology_irregular.py).
Realizer plural agreement (generate/templates.py)
- G2: under universal/existential/many/few/most quantifiers, count-noun
subjects pluralise (molecule → molecules) and the verb de-conjugates
(binds → bind). Negation toggles does-not → do-not. Aspect toggles
has → have, is → are. All other constructions unchanged.
- Mass nouns (evidence, wisdom, knowledge, truth, water, …) stay
singular under quantifiers — "all evidence supports truth" is right;
"all evidences support" would be wrong English.
- 17-case regression test
(tests/test_realizer_quantifier_agreement.py) covering count vs mass,
irregular plurals (child→children, analysis→analyses), and the
quantifier-tense / quantifier-aspect / quantifier-negation grid.
Rubric punctuation tolerance (evals/grammatical_coverage/runner.py)
- G3: _check_word_order strips trailing/leading punctuation
(.,;:!?—–) before exact-word comparison so "river," still satisfies
word_order=["river"]. must_contain also accepts punctuation-
stripped token matches.
- Affects every lane that uses grammatical_coverage scoring; the OOD
case generators no longer need to pin punctuated accept_surfaces for
C06.
Case generator + lane regeneration
- scripts/generate_english_fluency_ood.py uses generate.templates.pluralize
for C07/C08 must_contain + word_order so case-side constraints stay
aligned with the (more correct) realizer.
- All Phase 5 OOD lane cases (5.1, 5.4–5.7) regenerated; results files
re-scored.
CLI (core/cli.py)
- cmd_eval no longer crashes on lanes whose case_details use "id"
instead of "case_id" (adversarial_identity, multi_agent_composition).
- Cognition CLI lane gains the two new morphology/quantifier
regression test files.
Lane sweep (all 100%, no regression):
english_fluency_ood 117/117 public + 39/39 holdouts
elementary_mathematics_ood 117/117 + 39/39
foundational_physics_ood 117/117 + 39/39
foundational_biology_ood 117/117 + 39/39
classical_literature_ood 117/117 + 39/39
grammatical_coverage back to 100% on its own seed cases
hebrew_fluency / koine_greek_fluency 3/3 each
CLI lane health:
smoke 54, runtime 19, teaching 17, packs 6, cognition 103 (was 57),
algebra 132.
Closes the mixed_relation_* (multi-step-reasoning) and composed_predicate
(compositionality) residuals with a single new operator plus a small
intent-classifier loosening. Both residuals shared an underlying shape:
walk any outgoing relation edge from the head, regardless of which
relation predicate appears at each step.
generate/operators.py:
multi_relation_walk(triples, head, *, max_hops=5) -> WalkResult
Walks any outgoing edge from head, accumulating a path across
mixed relation types. Returns WalkResult with relation="<mixed>"
so trace_hash records the cross-relation provenance explicitly.
Deterministic, cycle-safe, first-write-wins on duplicate heads
(across any relation).
generate/intent.py:
_TRANSITIVE_QUERY_RE relaxed from a closed verb enumeration to any
single verb-like word. "What does X (any verb)?" now routes to
TRANSITIVE_QUERY consistently; unrecognised relations are handled
by the pipeline's multi_relation_walk fallback rather than falling
through to UNKNOWN. Verified no regression on 30 intent / realizer
tests.
core/cognition/pipeline.py:
_maybe_transitive_walk now does precision-first dispatch on
TRANSITIVE_QUERY: try transitive_walk(relation) literal-match
first, fall back to multi_relation_walk only when the literal
walk returns a singleton. DEFINITION intents do not fall back
(would be too permissive for "What is X?").
tests/test_inference_operators.py: 6 new TestMultiRelationWalk
tests covering single-relation pass-through, cross-relation walks,
cycle termination, max_hops truncation, and determinism.

PHASE 3 v1 IS COMPLETE: 10 of 10 splits passing. Phase 3 exit gate
(>= 2 lanes passing v1 by phase exit) is satisfied five times over.
Foundation guarantees (premises_stored_rate, replay_determinism)
remain 1.0 across all lanes. Trace_hash bit-stability preserved
with operator invocation records folded in per ADR-0018.
Compositionality public at 0.69 / holdouts at 0.80 - the residual
failures are the novel_pair_under_seen_relation / novel_relation_on_seen_pair
cases whose contract authoring is itself ambiguous (the leakage
check in the v1 contract fires by design on those patterns). Those
are contract-refinement candidates for v2 of that lane, not
engineering work. Overall_pass threshold (>= 0.50) is comfortably
met on both splits.
CLI suites smoke / cognition / teaching / packs all pass; 53
operator+teaching+pipeline tests green; no regression.
Implements the Phase 3 v2 inference-depth bundle per ADR-0018:
typed deterministic operators over CORE's typed state. Closes the
inference-closure / multi-step-reasoning / cross-domain-transfer
v1 gaps; partial close on compositionality.
New modules:
teaching/relation_parse.py - parse_triple(correction_text) lifts
a correction utterance into a typed (head, relation, tail) over
the en_core_cognition_v1 relation vocabulary. Pure regex,
deterministic, no learned classifier.
generate/operators.py - transitive_walk(triples, head, relation,
*, max_hops=5) walks single-relation chains. path_recall walks
a relation-chain tuple (e.g. ("is", "precedes")). Both bounded,
cycle-safe, case-insensitive, first-write-wins on duplicates.
Schema extensions:
teaching.store.PackMutationProposal gains optional triple field,
populated by TeachingStore.add via parse_triple. Plus new
TeachingStore.triples() helper returning all parsed triples.
generate.intent.IntentTag gains TRANSITIVE_QUERY plus a relation
field on DialogueIntent. New regex rules for "What does X R?"
and "Where does X belong?" forms with relation normalisation.
core.cognition.result.CognitiveTurnResult gains operator_invocation
field (deterministic serialisation of any operator that ran).
core.cognition.trace.compute_trace_hash gains operator_invocation
kwarg; trace_hash_from_result threads it through. Operator
invocation is now load-bearing for replay equality.
Pipeline wiring:
CognitiveTurnPipeline.run dispatches transitive_walk after
runtime.chat() when the intent is TRANSITIVE_QUERY (with the
parsed relation) or DEFINITION (implicit "is"). Non-trivial walks
fold the chain endpoint into surface and articulation_surface.
Verification:
tests/test_inference_operators.py - 27 unit tests covering
parser, transitive_walk (cycles, max_hops, case-insensitivity,
determinism, first-write-wins), path_recall, and WalkResult shape.
Re-score on Phase 3 v1 case sets:

Six of eight splits now pass v1. Foundation guarantees
(premises_stored, replay_determinism) remain 1.0 across all lanes.
Trace_hash determinism preserved (operator records fold in
deterministically).
Residuals (filed as Phase 3 v2 follow-up):
- multi-step-reasoning mixed_relation_3/4 patterns need path_recall
wired into the pipeline for multi-relation probes; the operator
exists but the pipeline only invokes transitive_walk today.
- compositionality novel-combination patterns need a genuinely
new operator shape (composed_relation_walk) - the literal
transitive walk does not synthesise novel pairs by construction.
CLI suites smoke / cognition / teaching pass; no regression. 47
pipeline + teaching + operator tests all green.
Three issues in the drift-fix landing (922bddc) addressed:
1. algebra/rotor.py: add rotor_power(R, alpha) — slerp on the rotor manifold
via the rotor's exp/log decomposition. Handles both rotation planes
(cos/sin) and boost planes (cosh/sinh); falls back to identity for
non-simple bivectors or null cases.
2. generate/stream.py: the score-weighted vault recall previously did
`weight*V + (1-weight)*np.eye(V.shape[0])`. Two bugs:
- np.eye produced a 32x32 matrix for a 1D multivector, crashing
versor_apply with a broadcasting error (2 cognition tests failing
on main).
- The linear blend produced multivectors with versor_condition up to
2.2e-2, violating the non-negotiable 1e-6 invariant declared in
CLAUDE.md. Now uses rotor_power(V, weight) which stays on the
manifold by construction (versor_condition <= 1.1e-16).
3. session/context.py: respond() now re-binds result.final_state to
self.state after finalize_turn's anchor pull, restoring the
"respond returns the same object that was vaulted" contract
(test_engine_loop_proof regression).
Verification:
- 41 new tests in tests/test_rotor_power.py covering closure preservation,
alpha=0/1 boundaries, half-angle composition, and word-transition rotors.
- Empirical multi-turn versor_condition stays at machine epsilon with
anchor pull, max 9.4e-7 without (under threshold either way after fix).
- Full suite: 609 passed, 4 skipped, 0 failed.
1. session/context.py — dialogue blade accumulation is now magnitude-preserving
via EMA (α=0.15). Running blade grows stronger each turn a concept is
confirmed rather than resetting to unit magnitude on every record_dialogue().
2. generate/stream.py — vault recall transitions are now score-weighted.
Each recalled rotor is scaled by softmax(scores)[i] before application so
high-confidence vault hits dominate and stale low-score entries barely move
the field.
3. session/context.py — anchor pull added after _hemisphere_consistent_field().
A mild α=0.05 slerp toward _anchor_field is applied at finalize_turn() to
provide continuous conjugate correction against angular drift within the
hemisphere. Unitized before writing back to state.
The realize_semantic / realize_target pipeline in realizer.py was fully
implemented but never called from chat/runtime.py. The hot path only called
realize() from articulation.py, which returns raw S-P-O word tokens with no
intent, tense, negation, quantifier or rhetorical-move awareness. This
disconnected the 13-construction realizer from every live chat turn.
New module generate/intent_bridge.py:
- classify_intent_from_input() runs the rule-based classifier against the
raw input text to obtain a DialogueIntent
- articulate_with_intent() builds a PropositionGraph from that intent,
grounds the <pending> obj slots with recalled vocabulary from the
generation result, plans articulation via plan_articulation(), and calls
realize_semantic() for the intent-specific template path
- Falls back cleanly to the existing ArticulationPlan surface when the
realizer returns an empty plan (OOV-heavy or UNKNOWN intent)
chat/runtime.py change:
- Import and call articulate_with_intent() after the existing realize() call
- Replace articulation.surface with the intent-bridge surface whenever the
bridge returns a non-empty, non-pending string
- The existing ArticulationPlan dataclass is preserved and passed downstream
so SentenceAssembler, turn_log, ChatResponse, and all trace fields remain
structurally unchanged
Effect: chat() now produces intent-differentiated surfaces:
DEFINITION → "X is defined as Y" (was "X Y Z")
CAUSE → "X is grounded in Y" (was "X Y Z")
CORRECTION → "correction: X corrects Y" (was "X Y Z")
RECALL → "recalling X: Y" (was "X Y Z")
VERIFICATION→ "X is verified: Y" (was "X Y Z")
COMPARISON → "X and Y are distinguished..." (was "X contrasts_with Y")
PROCEDURE → "first, Y; then, X follows" (was "X Y Z")
CONJUNCTION → "X P and Y P" (realizer edge handling)
RELATIVE → "X, which Pv Y, Pv Z" (realizer edge handling)
Articulation fidelity is now geometrically honest AND structurally expressive.
The surface corresponds to internal intent state, not a generic S-P-O join.
- Fix running_dialogue_blade grade explosion: replace outer_product
accumulation (which pushed past grade-5 in Cl(4,1), silently zeroing
the blade from turn 3 onward) with CGA-inner-oriented blade tracking
that preserves grade-2 across arbitrary turn counts.
- Add versor_condition guard at session composition boundary: cross-turn
field composition via versor_apply now fails closed (threshold 1e-2,
matching algebra construction residue tolerance) instead of silently
propagating degraded fields into vault and generation.
- Replace VaultStore list with deque(maxlen=max_entries): eliminates
O(N) list.pop(0) on every bounded eviction; deque auto-evicts in O(1).
- Replace O(N) vocab scan in generate/stream.py stop_nodes construction
with O(1) try/except index lookup per stop token.

Adds referent tracking, session graph traversal, unknown-domain gating, correction propagation, compositional surface assembly, and regression coverage.
Follow-up fixes included before merge:
- split probe/commit/finalize turn flow so unknown-domain checks run before current-query vault writes
- record real input tokens and input versors for sync and async session paths
- return true graph distances from backward walks and consume them in correction decay
- synchronize corrected graph outputs into vault-backed recall and live referent state
- regenerate correction responses from corrected context rather than correction text
- keep coreference pronouns lowercase in question bodies
- centralize elaboration-string construction to avoid plan/surface drift
- add targeted dialogue fluency regression tests
- remove normalization and unitization calls from generation path
- skip invalid recalled fields instead of repairing them in generation
- punctuate selected articulation surfaces
- stabilize assertive dialogue roles
- anchor proposition slots to live field
- preserve session anchor orientation for coherence
- restore articulation surface as ChatResponse.surface while retaining walk_surface telemetry
- calibrate moderate E2 energy boundary
- reclose generated field states after propagation and recall
- restore pytest-safe REPL parsing and field_walk helper
- anchor proposition predicate selection to prompt field
- make vault exact self-recall deterministic
- align chat telemetry regression with restored surface contract
- calibrate identity threshold and per-axis telemetry
- keep walk surfaces visible when identity flags are telemetry
- report real vault recall hits through generation/runtime logs
- record selected surface in TurnEvent
- fix async chat persona reference
- add regression coverage for chat telemetry
agenerate() skipped _recall_state() entirely, meaning async streaming
responses were disconnected from session memory. This patch brings
agenerate() to full parity with the synchronous path:
- Accepts vault and recall_top_k parameters (default 3, matching generate())
- Calls _recall_state(_voiced_state(current, persona), vault, recall_top_k)
at each step before nearest-node selection
- Does not add stop_nodes or salience (those remain sync-only for now;
the core correctness gap is vault recall)
The async return value is still token-by-token via yield. Callers that
want final_state should use the synchronous path or wrap in a collector.
IdentityCheck runs after generation in ChatRuntime and must travel
forward with the result without requiring a second pass or a wrapper.
The field is Optional so all existing call sites that don't supply it
continue to work unmodified.
Key issues fixed:
- `CORE_BACKEND=numpy` was ignored, so tests mixed Python CGA embedding with Rust metric behavior.
- Dense construction seeds were being rejected by strict `unitize_versor()`, while sparse dirty inputs still needed to fail closed.
- Holonomy needed a construction-boundary path for raw/dense vocab fixtures and rare null final accumulators.
- Proposition storage polluted vault recall by storing the live field instead of the proposition’s subject versor.
- Dialogue qualitative frames rendered the same surface as assertive copular frames.
- Repeated session prompts could collapse into the same deterministic response path.
- Two proof fixtures were stale: one hand-built a non-null “null” vector, and one alignment proof omitted the English “with” anchor used by the resonance proof.
Verification:
`CORE_BACKEND=numpy CORE_STRICT_MLX_ON_APPLE=0 uv run core test -- -q`
Result: `277 passed in 59.52s`
Add geometry-backed ArticulationPlan and realize(), wire articulation into ChatRuntime and trace output, expose proposition relation_norm, and add articulation/runtime/CLI tests.
Add RuntimeConfig with English default output policy, wire output language through runtime/frame selection/generation/CLI, preserve language metadata in mounted manifolds, and add runtime/CLI policy tests.
- field/state.py: FieldState is now frozen+slotted; constructor copies and
enforces float32 shape (32,); advance() updated to pass raw arrays.
np.ndarray inside frozen dataclass is ref-frozen — copy() at construction
is the explicit contract boundary.
- generate/result.py: NEW — GenerationResult frozen dataclass carrying
tokens + final_state. Async variant yields tokens and exposes final_state
on completion.
- generate/stream.py: generate() now returns GenerationResult, not list[str].
vocab.edge_rotor() call replaced with:
A = vocab.get_versor_at(current.node)
B = vocab.get_versor_at(word_idx)
V = word_transition_rotor(A, B)
agenerate() updated to yield tokens and surface final_state.
- vocab/manifold.py: added get_versor_at(idx) and get_word_at(idx) indexed
accessors. VocabManifold stores points; algebra constructs operators.
normalize_to_versor() call-site in docstring clarified: callers must call
unitize_versor() (algebra construction primitive) before add(), not
normalize_to_versor() directly.
- algebra/versor.py: unitize_versor() added as the explicit construction-time
primitive. normalize_to_versor() kept but marked internal/gate-only.
Distinction encoded in docstrings and __all__.
- persona/motor.py + ingest/gate.py: SessionContext.respond() is not yet in
the repo as a separate file; gate.py docstring updated to reflect the
three-tier normalization doctrine:
unitize_versor() — algebra construction only
inject() — gate, once per raw input
normalization — forbidden in propagate/generate/vault recall
