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.
Replaces the cognition-shape-uniform threshold dispatch in
core/capability/expert_demo.py with an explicit LANE_SHAPE_REGISTRY
mapping 8 ratified lane ids to 5 shapes:
cognition -> cognition_shape
elementary_math_ood -> accuracy_shape
foundational_physics_ood -> accuracy_shape
symbolic_logic -> symbolic_logic_shape
hebrew_fluency -> accuracy_shape
koine_greek_fluency -> accuracy_shape
inference_closure -> inference_shape
fabrication_control -> refusal_shape
Each shape has a documented threshold checker. Unknown lane ids
fail-closed with a named reason. ADR-0106 \xc2\xa71.1/\xc2\xa71.3/\xc2\xa71.4/\xc2\xa71.5
unchanged; only \xc2\xa71.2 (threshold rules) dispatches by shape.
tests/test_lane_shape_thresholds.py pins all four ADR-0109 invariants
plus dead-shape and threshold-value gates (13 new tests).
tests/test_expert_demo_contract.py fixtures updated to provide
shape-appropriate metrics (no semantic change to those tests; same
12 cases still pin the ADR-0106 contract).
ADR-0109 status: Proposed -> Accepted. README sequencing updated
(ADR-0110 now only blocked by inference_closure, not by metric-shape
amendment).
Ledger: all five domains remain reasoning-capable, expert_demo=false.
Amends ADR-0106 \xc2\xa71.2 to dispatch threshold rules by lane shape rather
than imposing cognition-pack-shape metrics uniformly. ADR-0107
surfaced that every non-cognition lane was failing the gate by
absence-of-key, not by substance.
Status: Proposed. Ships five shapes covering every lane currently
attached to a ratified pack: cognition_shape, accuracy_shape,
inference_shape, refusal_shape, symbolic_logic_shape. Four invariants
pinned. Unknown lanes fail closed; new shapes require ADR amendment.
\xc2\xa71.1 (reasoning-capable prereq), \xc2\xa71.3 (signature scoping), \xc2\xa71.4
(domain-aware), \xc2\xa71.5 (replay byte-equality) all preserved. ADR-0106
status remains Accepted.
The ADR-0106 contract correctly refused promotion. ADR-0107 records the
deferral and reserves two follow-up ADRs:
- ADR-0109 (lane-shape-aware threshold amendment): ADR-0106 \xc2\xa71.2
prescribes cognition-pack-shape metrics uniformly, but math /
physics / systems / hebrew-greek lanes carry native shapes
(accuracy, passed_rate, all_pass_rate). Prerequisite for any future
expert-demo promotion.
- ADR-0110 (math re-attempt): conditional on ADR-0109 landing and
inference_closure substantively passing (currently all_pass_rate=0.4
on public).
tests/test_adr_0107_deferral.py pins adr_0107_no_silent_promotion: math
stays at reasoning-capable, has no expert_demo_claims entry, and the
ledger row carries a named refusal reason.
No change to core/capability/expert_demo.py or reporting.py -- the
contract is honored, not amended. README sequencing updated to reflect
ADR-0107 acceptance and the new ADR-0109/0110 prerequisites.
Closes ADR-0106 acceptance evidence:
- ExpertDemoClaim dataclass + additive expert_demo_claims block on
ReviewerRegistry (schema_version stays at 1; backward-compatible).
- New core/capability/expert_demo.py with derive_evidence_digest,
evaluate_expert_demo, collect_domain_lanes, materialise_lane_results.
- core/capability/reporting.py: replaces the cognition-lane-only
predicate (previous lines 418-433) with a domain-aware,
reviewer-signed gate; ledger rows now also carry
expert_demo_reason for operator legibility. Reviewer registry is
fail-closed: an unloadable registry yields zero claims, so a broken
registry never silently grants expert_demo=true.
- tests/test_expert_demo_contract.py covers all three ADR-0106
invariants: requires_signature, domain_aware, replay_byte_equality;
plus threshold + production-ledger-untouched gates. 12 new tests.
- tests/test_reviewer_registry.py extended with TestExpertDemoClaimsSchema
covering omitted block, valid parse, unknown signer rejection,
malformed digest rejection, duplicate domain rejection. 5 new tests.
- README index row + table preface updated to note expert_demo is
contract-gated. Frontier list trimmed (ADR-0106 has landed).
- ADR-0106 Status flipped Proposed -> Accepted.
No domain row's expert_demo field flips by this PR -- only the contract
changes. Promotion of any ratified domain requires a follow-up ADR
(ADR-0107 reserved for mathematics_logic) plus a signed claim.
- ADR-0108 Status: Proposed -> Accepted
- README index row updated to Accepted
- 'Current frontier' rewritten with the ranked Proposed-ADR list mandated
by ADR-0108 \xc2\xa7Decision; removes the now-false 'No ADR currently sits in
a "Proposed but unimplemented" state' sentence
- Open candidate directions (no-ADR-yet) section retained for the
multi-reviewer governance frontier item from ADR-0105
Makes the post-ADR-0105 sequencing of ADR-0080 / 0084 / 0087 / 0106
explicit, durable, and revisable. Status: Proposed. No content of the
four sequenced ADRs is modified — sequencing is meta, not content.
Defines a domain-aware, reviewer-signed expert_demo promotion gate to
replace the current cognition-lane-only predicate in
core/capability/reporting.py:418. Status: Proposed. This ADR does not
promote any domain — it defines the contract that a follow-up ADR (likely
mathematics_logic as ADR-0107) will consume as the first worked
promotion.
Sibling reconciliation PR to #104. The four ADRs explicitly called out as
the 'current implementation frontier' in PR #104 are already implemented
to the same evidence bar as the eight ADRs that PR accepted:
- ADR-0094: teaching/source.py + proposal schema widening + migration
script; tests/test_proposal_source.py green
- ADR-0095: teaching/from_miner.py + miner_loop_closure lane;
SHA-pinned in scripts/verify_lane_shas.py; tests/test_miner_proposals.py
green
- ADR-0098: core/demos/contract.py + adapter surface + demo_composition
lane; SHA-pinned; tests/test_demo_composition.py green
- ADR-0099: core/demos/showcase.py + public_demo lane;
SHA-pinned; tests/test_public_showcase.py green
Three of four lanes are SHA-pinned in CI (a stricter bar than several
already-accepted ADRs). Local pytest run: 85/85 passed across the four
tests/test_*.py files in 17s.
Also refreshes docs/decisions/README.md:
- flips the four table rows to Accepted (2026-05-22)
- rewrites the 'Current frontier' section now that no ADR-0091..0102
entry is unimplemented
- enumerates candidate next directions (curriculum proposals,
language-specific holdout splits, expert-demo ratification)
Docs-only change; no runtime code touched.
CLAIMS.md is now mechanically derived from two ground-truth sources:
- core.capability.ledger_report (Tier 1: ratified domains)
- scripts/verify_lane_shas.PINNED_SHAS (Tier 2: pinned lane reports)
The generator is deterministic and gated by
tests/test_claims_md_is_current.py + the lane-shas CI workflow's new
'verify CLAIMS.md is current' step. Drift between in-tree state and
the published claims fails CI before merge.
Tier 1 (5 ratified domains) and Tier 2 (6 pinned lanes) cover every
ADR-0092..0102 invariant currently CI-pinned.
Two pre-existing latent issues fixed:
1. discourse_planner flag catalog drift (test_flag_report failure)
On 2026-05-21 the discourse_planner default was flipped to True
after byte-equality verification (per inline comment in
core/config.py:130-138), but the capability flag catalog at
core/capability/reporting.py was not updated — it still claimed
"flag_shipped_default_off". The test
test_flag_report_tracks_default_off_flags_without_enabling_them
correctly caught the inconsistency; it had been failing across
every commit since ADR-0092 first ran the suite.
Fix:
- New "flag_shipped_default_on" state in _FLAG_CATALOG, added
to flag_report() grouped output
- discourse_planner moved from default_off → default_on
- Test renamed to test_flag_report_classification_matches_actual_defaults,
enforces BOTH directions of the contract (catalog claim must
match DEFAULT_CONFIG value)
- New test test_flag_catalog_state_is_consistent_with_default_config
cross-checks every catalog entry against DEFAULT_CONFIG;
catches future drift before it lands
2. public_demo lane SHA shifted every commit
Each commit advances the showcase's generated_at_revision field
(git HEAD SHA). _strip_volatile in the lane runner was stripping
wall-clock and per-run paths but NOT generated_at_revision, so
the byte-equality case's details.sha256 changed with every commit
even when underlying demos produced identical content. That made
the pin a "did this run today" check rather than a "did the code
produce the right artifact" check — exactly the failure mode
the verifier was supposed to prevent.
Fix:
- Add generated_at_revision to _VOLATILE_KEYS in the public_demo
runner. Lane's invariant is "same code → same SHA," not
"same HEAD → same SHA"; HEAD belongs in the showcase output
(operators need it) but not in the lane's equality projection.
- Pin refreshed once to capture the now-commit-independent SHA;
subsequent commits won't shift it unless underlying demo content
actually changes.
After fix:
- Capability tests: 6/6 passing (was 4/5 with discourse_planner failing)
- Lane SHAs: 6/6 match pinned values; public_demo pin will now survive
routine code changes
- Smoke 67/67, cognition eval byte-identical 100/100/100/100
This is the single known pre-existing test failure cleaned up.
Six lanes (reviewer_registry, miner_loop_closure,
domain_contract_validation, fabrication_control_summary,
demo_composition, public_demo) now have CI-enforced SHA-256 pins.
A failing job means a lane's deterministic output changed without
an explicit ADR-tracked pin update.
- new scripts/verify_lane_shas.py: single source of truth
- PINNED_SHAS dict mapping lane_id → 64-char hex SHA
- LANE_SPECS tuple wiring each lane to its runner module + canonical
report path
- accepts_report_flag handles the fabrication_control runner's
different arg shape (--lane-dir not --report)
- verify_all() runs each lane in subprocess isolation (clean Python
state per lane — relevant for adapters that cache pack loads at
module import)
- --update flag refreshes pins after intentional ADR-tracked changes;
diff is the audit trail
- --json flag emits machine-readable report
- exits non-zero on any mismatch
- new .github/workflows/lane-shas.yml:
- triggers on push to main and pull_request to main
- concurrency group cancels in-progress runs on new commits
- Python 3.11 + pip-cached deps + editable install
- runs verify_lane_shas.py; emits JSON report on failure
- 12-minute timeout (lanes take ~30s in practice)
- new tests/test_lane_sha_verifier.py: cheap local-pytest pinning
- every LaneSpec has a corresponding PINNED_SHAS entry
- no orphan pins without a LaneSpec
- every pin is a 64-char hex SHA-256
- every runner module path exists on disk
- canonical report paths are under repo root
- all six expected lanes (ADR-0092/0093/0095/0096/0098/0099) covered;
ADR-0094 and ADR-0097 are schema/ratification only, intentionally
excluded from EXPECTED_LANES
- 6 tests run in <100ms — catches drift before CI
- evals/public_demo/results/v1_dev.json: refreshed to match the new
pin (21751aaf..) — earlier pin was generated under slightly different
runner argparse defaults; --update produced the canonical bytes
Local verifier: 6/6 lanes match pinned SHAs. Smoke 67/67. Lane SHAs:
reviewer_registry 681a2aab..

fabrication_control_summary 01e1b6b7..
demo_composition 27d83824..
public_demo 21751aaf..
Single 30-second artifact composing four CORE invariants
(determinism, honest unknown, reviewed learning, multi-hop with
trace) by delegating to existing DemoCommand adapters. **No new
mechanism** — every claim is backed by an already-shipped,
separately-tested adapter. Closes the 8-ADR scale-up slate.
- new core/demos/learning_loop_adapter.py: LearningLoopDemo wraps
ADR-0056 reviewed-teaching loop; _strip_volatile_paths drops
transient temp-dir paths from raw before serialization so the
adapter's report_sha256 is content-stable across runs
- new core/demos/showcase_adapters.py:
- FabricationControlPublicDemo: re-runs ADR-0096 public split,
produces 3 claims (refusal_recall_meets_threshold,
fabrication_rate_below_threshold, trace_evidence_present)
- MultiHopTraceDemo: runs 'Does light reveal truth?' with
transitive_surface=True + composed_surface=True against
cognition pack; surfaces a 3-hop walk light→truth→knowledge→
evidence; produces 3 claims (grounded_answer, depth_two_or_more,
walk_evidence_present)
- new core/demos/showcase.py: run_showcase() composes 4 scenes,
emits showcase.json + per-scene artifacts; render_html() produces
presentation-only static HTML with no JS injection vector;
ShowcaseScene dataclass; MAX_RUNTIME_SECONDS=30 hard ceiling
with DemoContractError if exceeded
- CLI: 'showcase' added to demo target choices; --output-dir flag
added; cmd_demo dispatch branch writes showcase.json + showcase.html
- new evals/public_demo/ lane with 4 cases:
- all_claims_supported (each scene + composite)
- determinism_run_to_run_byte_equality (two runs identical after
stripping volatile keys: total_runtime_ms, json_path,
transient_corpus)
- runtime_under_budget (≤30s)
- pure_composition_no_new_mechanism (grep gate over showcase
imports — must come from core/chat/generate/language_packs/
teaching/evals or allowed stdlib only)
- lane is itself byte-identical across runs (sha256 5707db8efc6a..);
runtime case omits exact runtime_ms (it varies near bucket
boundaries) but still asserts ≤ budget
- 8 unit tests with module-scoped fixture (showcase runs once,
~13s total) covering payload shape, scene order, runtime budget,
HTML render absence of <script>, and the pure-composition import
gate independently of the lane
- ADR-0099 measured: total_runtime_ms ~12.8s, well under 30s budget
- smoke 67/67, cognition eval byte-identical 100/100/100/100;
all 6 ADR-0092..0099 lanes byte-identical:
reviewer_registry 681a2aab..
miner_loop_closure 9f071733..
domain_contract_validation f9c06cde..
fabrication_control sum 01e1b6b7..
demo_composition 27d83824..
public_demo 5707db8e..
DemoCommand Protocol + thin adapters retrofit shipped tours to a
typed composition contract. Composability becomes a structural
property: the ADR-0099 showcase will consume DemoResult through one
stable type rather than special-casing each tour. No demo behavior
changes — adapters wrap underlying run_tour() entry points.
- new core/demos/ package:
- contract.py: frozen Claim / DemoResult dataclasses, runtime-checkable
DemoCommand Protocol, canonical_json() sanctioned serializer
(sorted keys, 2-space indent, trailing newline), CLAIM_CONTRACT_VERSION
- audit_tour_adapter.py: AuditTourDemo (5 claims from ADR-0042 scenes
1-4: identity_pack_swaps_visible, safety_typed_refusal,
ethics_opt_in_deployment_fires, ethics_default_silent,
replay_byte_identical)
- tour_adapters.py: shared pattern for register/anchor-lens/orthogonality
tours; _extract_claims walks the dict tree for *_supported booleans
and builds Claim objects in deterministic sorted order
- global-state-mutation detector (ADR-0098 invariant #2):
capture_state() snapshots a load-bearing subset of process state
(CORE_* env vars + module identities for chat.telemetry,
chat.runtime, language_packs.compiler);
verify_no_global_state_mutation() ignores None→id transitions
(benign lazy import) and only flags env-var changes or module
identity rebindings
- new evals/demo_composition/ lane (ADR-0098 invariant proving):
- 6 cases asserting byte-equality + no-state-mutation across the
three fast adapters (audit-tour, register-tour, orthogonality-tour)
- composition_read_only: confirms two adapter results compose into
a composite claim set without mutating either
- stateful_fixture_rejected: negative control — a deliberately
stateful adapter MUST trigger divergence detection
- anchor-lens-tour adapter is exercised by tests, not the lane,
to keep wall time bounded
- byte-identical across runs (sha256 27d838241bf3..)
- 26 unit tests covering Claim/DemoResult validation, canonical_json
determinism, state-mutation detector (including the lazy-import
benign case), Protocol conformance (isinstance check + claim
contract version) for all four adapters, seed-rejection per
adapter (all current adapters are fully deterministic), and an
audit-tour integration smoke verifying 5 claims + byte-equality +
no state mutation across two consecutive runs
- smoke 67/67, cognition eval byte-identical 100/100/100/100, all
five lanes byte-identical (reviewer_registry 681a2aab..,
miner_loop_closure 9f071733.., domain_contract_validation f9c06cde..,
fabrication_control summary 01e1b6b7.., demo_composition 27d83824..)
First concrete domain claim under ADR-0091's Domain Pack Contract v1.
en_mathematics_logic_v1 is now formally ratified as reasoning-capable
in the capability ledger: 9/9 ADR-0091 predicates pass.
ADR-0097 §"No code changes outside pack artifacts and corpus" relaxed
to include two latent bug fixes that ADR-0093's predicate enforcement
just exposed:
1. language_packs/schema.py: LanguageRole enum widened to include
DOMAIN_SEED. Three in-tree packs (en_mathematics_logic_v1,
en_physics_v1, en_systems_software_v1) have declared role="domain_seed"
since landing but the enum was never updated; load_pack() always
raised on them. ADR-0093's P1 predicate exposed the mismatch.
2. core/capability/domain_contract_predicates.py: P2 (gloss checksum)
was reading manifest["checksums"]["glosses_sha256"]; the canonical
in-tree location is manifest["glosses_checksum"] (top-level). Fixed
to prefer the canonical key and fall back to the nested form for
forward compatibility.
ADR-0097 manifest additions to en_mathematics_logic_v1:
- domain_contract_version: 1
- domain_id: "mathematics_logic"
- axioms: null (rules in v1 — pack proves reasoning via chain
composition, not declarative axioms)
- rules: null
- teaching_chains: ["mathematics_logic_chains_v1"]
- eval_lanes: three lanes with dev/public/holdout (elementary_mathematics_ood,
inference_closure, fabrication_control)
- reviewers: ["shay-j"] (resolved via ADR-0092 registry)
- known_gaps: [] (all math/logic gaps in docs/gaps.md were [x])
- provenance: "adr-0097:reviewed:2026-05-21"
Verified evidence:
- core capability domain-contract --pack-id en_mathematics_logic_v1
→ all_passed=True (P1-P9 all pass)
- core capability ledger → mathematics_logic row shows
status=reasoning-capable, predicates.reasoning_capable=True,
predicates.expert_demo=False, open_gaps=[],
operator_chain_coverage all ready=True (8 chains each),
intent_shapes_present=5
- 14 ADR-0097 invariant tests in
test_adr_0097_mathematics_logic_ratification.py pin
status/provenance/expert-demo-gate/contract shape
Two pre-existing tests updated for the new CLI default
(predicate-running, non-zero on missing contract):
- test_capability_domain_contract_json_absent_contract_is_noop now
uses --structural-only to assert legacy parse-only shape
- test_cli_returns_nonzero_on_missing_contract switched its fixture
pack from en_mathematics_logic_v1 (now has a contract) to
en_core_cognition_v1 (no contract)
The pre-existing test_flag_report_tracks_default_off_flags failure
(discourse_planner flag default mismatch, seen since ADR-0092) is
unchanged and unrelated.
Smoke 67/67, packs 6/6, capability tests 49/50, cognition eval
byte-identical 100/100/100/100; lanes byte-identical:
reviewer_registry 6/6, miner_loop_closure 6/6,
domain_contract_validation 9/9, fabrication_control dev 12/12 +
public 9/9.
First negative-control measure. Proves the runtime refuses (or
honestly limits) on composable-looking but unsupported prompts
rather than synthesizing phantom answers. Mirrors the ADR-0022
forward-semantic-control structure: constrained run plus reported
coincidence rate.
- new evals/fabrication_control/ lane with three case classes:
- Class A (phantom_endpoint): nonsense vocabulary outside the
runtime's lexicon → expected grounding_source ∈ {none, oov}
- Class B (cross_pack_non_bridge): English vocab spanning two
mounted packs with no alignment/teaching_chains bridge →
expected grounding_source = none
- Class C (sibling_collapse): prompt conflating two distinguished
lemmas → expected refusal of conflation, grounding_source = none
- pinned thresholds frozen at lane creation:
fabrication_rate ≤ 0.01, refusal_recall ≥ 0.95,
trace_evidence_present == 1.00,
grounding_source_matches_expected == 1.00
- three-set discipline per docs/capability_roadmap.md Rule 1:
cases/dev.jsonl (12 cases, 4/class), cases/public.jsonl (9 cases),
cases/holdout.jsonl (empty — reserved for first version cut)
- runner.py drives each case through ChatRuntime.chat(), captures
surface + grounding_source, computes the five metrics, and
evaluates against pinned thresholds; public-split violations
cause non-zero exit; dev/holdout always report but never block
- coincidence_rate reported as 0.0 with a note that unconstrained
baseline is reserved for future comparison (the current runtime
is fully constrained)
- 30 unit tests covering refusal/fabrication marker detection,
metric computation, threshold evaluation, case loading, plus a
one-case ChatRuntime integration smoke
- v1 results:
dev: n=12 refusal_recall=1.0 fabrication_rate=0.0 PASSED
public: n=9 refusal_recall=1.0 fabrication_rate=0.0 PASSED
- byte-identical across runs (dev sha256=d6757e0e3f96..,
public sha256=9b502878fcb7.., summary sha256=01e1b6b71114..)
- smoke 67/67, teaching 17/17, cognition 120/121 (pre-existing skip);
cognition eval byte-identical 100/100/100/100
Closes the Phase-5 contemplation loop in code. Articulation-quality,
contradiction-detection, and frontier-compare miners (already shipping)
now have a route to file PackMutationProposal candidates that traverse
the single reviewed teaching path. Construction-only; never promotes
to coherent.
- new teaching/from_miner.py: from_finding() / from_findings() turn
ContemplationFinding records (kind=PACK_MUTATION_CANDIDATE) into
PackMutationProposal candidates with source.kind="miner",
source.source_id=<miner_id>, status=SPECULATIVE
- proposal_id = SHA-256(canonical(miner_id, finding, revision))[:16]
— same inputs → byte-identical proposal_id; different miner_id or
revision → different id
- identity-pack defense AT CONSTRUCTION: reuses teaching.review.
_is_identity_override() against finding.subject AND
finding.proposed_action; miner-sourced identity-override attempts
never reach the proposal log
- pluggable ReplayEquivalenceChecker Protocol with ReplayEquivalenceResult;
NoOpReplayChecker default explicitly notes "deferred to production
checker"; production checker integration is downstream of this ADR
- from_findings() batch path collects identity-override and
replay-equivalence rejections in a typed rejection log rather than
raising, so a mixed batch can proceed with audit evidence
- serialize_proposal_emitted_event() emits ADR-0040-compliant redacted
telemetry shape: type, proposal_id, source.serialize(),
epistemic_status only (no raw subject/correction_text)
- 22 unit tests covering positive construction, identity defense in
subject+proposed_action, malformed input, determinism (same inputs,
different revision, different miner_id, batch stream), replay
pre-gate (single + batch), telemetry redaction, and the structural
grep gate enforcing miner_proposal_single_review_path (only
teaching/review.py and teaching/store.py may promote to COHERENT)
- new evals/miner_loop_closure/ lane: 6 case classes (positive_basic,
identity_override_subject, identity_override_action,
replay_equivalence_failed, wrong_finding_kind, determinism) passing
6/6 with byte-identical SHA-256 across runs
- smoke 67/67, teaching 17/17, cognition 120/121 (1 pre-existing skip);
cognition eval byte-identical 100/100/100/100
Closes the load-bearing gap blocking every reasoning-capable claim
under ADR-0091: docs/reviewers.yaml was previously `reviewers: []` and
unparsed. Now schema-validated at v1, with a bootstrap shay-j entry
self-sealed via provenance.
- new core.capability.reviewers module: frozen Reviewer/ReviewerRegistry
dataclasses, strict load_reviewer_registry parser, ReviewerRegistryError
- enforces ADR-0092 schema rules: schema_version==1, no unknown
top-level keys, no unknown reviewer fields, role∈{primary,domain},
primary must claim ["*"], domain must NOT claim "*", review_scope
subset of {pack,proposal,chain,eval}, no duplicate reviewer_ids
- can_review(reviewer_id, domain_id, scope) helper implements
ADR-0092 rules 2-4 for downstream use by ADR-0093 validator
- docs/reviewers.yaml updated to v1 schema with shay-j bootstrap
- ledger_report() evidence_counts now exposes structured
reviewer_registry status (valid, schema_version, reviewer_count,
reviewer_ids, error) alongside the legacy reviewers_present bool
- new evals/reviewer_registry/ lane: 6 cases (2 positive + 4 negative)
covering empty-registry, wrong-version, domain-wildcard rejection,
and unknown-field rejection
- runner emits deterministic JSON report; two runs produce byte-identical
output (sha256 verified)
- 26 unit tests in tests/test_reviewer_registry.py
- capability ledger test extended to assert new reviewer_registry block
- smoke suite green (67/67); lane passes 6/6
The pre-existing test_flag_report_tracks_default_off_flags failure is
unrelated (discourse_planner flag default) and not introduced here.
Eight load-bearing ADRs closing the loop from contemplation Phase 5 through
a public showcase demo. Each one is small and evidence-bearing; together
they sequence the next arc without duplicating existing substrate.
- 0092 Reviewer Registry v1 — populates docs/reviewers.yaml schema;
unblocks all reasoning-capable claims under ADR-0091.
- 0093 Domain Pack Contract v1 Implementation — wires ADR-0091's five
follow-up items (parser, dry-run validator, chain registry, eval lane
refs, reviewer resolution) so manifest fields actually gate status.
- 0094 Proposal Source Provenance — sealed ProposalSource type widening
proposal schemas ahead of 0095.
- 0095 Miner-Sourced Teaching Proposals — closes the contemplation
loop: articulation_quality / contradiction_detection / frontier_compare
miners emit PackMutationProposal candidates routed through the single
reviewed teaching path; identity-pack defense at construction, not
review; replay-equivalence pre-gate.
- 0096 Fabrication-Control Eval Lane — first negative-control measure;
three case classes (phantom endpoint, cross-pack non-bridge, sibling
collapse) with frozen thresholds (fabrication_rate ≤ 0.01).
- 0097 Mathematics-Logic Reasoning-Capable Ratification — first
domain claim under ADR-0091; chain corpus + eval lanes already
exist, this is the formal contract ratification.
- 0098 Demo Composition Contract — DemoCommand protocol so demos can
be composed without reimplementation; deterministic JSON, no global
state mutation, declared output paths only.
- 0099 Public Showcase Demo — composes four scenes (determinism /
honest unknown / reviewed learning / multi-hop+trace) under 30s;
pure composition enforced by grep gate; JSON byte-equality CI-pinned.
Landing order: 0092 → 0094 → 0095 → 0093 → 0096 → 0097 → 0098 → 0099.
Deliberately not included: curriculum compiler, formation course
runner, calculator operators, response-mode taxonomy expansion,
learning-scale 10k harness. Each is deferred with a documented reason.
Phase 5 landed in commit 327047c (articulation-quality miner +
runtime sink wiring + full end-to-end loop tests). Extending the
session note in-place per its own append-only convention so the
single document covers the complete arc Phases 1–5.
Sections updated
----------------
* §0 executive summary
- commit count: 9 → 11
- phases shipped: 4 → 5 (new Phase 5 row in the deliverables
table)

``attach_articulation_sink`` and
``mine_articulation_observations``
- test artifacts: 6 → 8 files, 64 → 82 cases
* §3.5 NEW — full architectural walkthrough of Phase 5
- Why the loop closes (links the user's

doctrine-aligned realisation: reviewable evidence, not
autonomous mutation)

- Recorded demo output from the commit message
- Doctrine pin table mapping each constraint to its test
* §4 pipeline diagram extended to show Phase 5 sink + offline
miner branches
* §5 verification table gains four new rows for Phase 5 claims
(full-loop emission, byte-equal finding IDs across two e2e
runs, JSONL round-trip identity, opt-in gating)

closing one-line story across all five phases for one prompt
("What is truth, and why does it matter?")
* §7 architecture surfaces table grows a row for
chat/articulation_telemetry.py and adds the miner to the
contemplation subsystem row
* §9 inverted from "what would close the loop" (future work) to
"SHIPPED — here's what it now unlocks":
- production sink + retention policy
- additional aggregation rules
- CLI hook
- review-loop wiring back into PackMutationProposal
* §10 reference index grows new lines for
chat/articulation_telemetry.py,
core/contemplation/miners/articulation_quality.py,
tests/test_articulation_quality_miner.py, and
tests/test_articulation_quality_e2e.py
* Footer updated: notes the arc is complete; future arcs should
start a new session-notes file and cross-link rather than
rewriting this one.
The session-notes file is now 1100+ lines — the complete frozen
reference for the articulation arc that took CORE from one-sentence
pack-grounded surfaces to a full live-reasoning + offline-mining
+ reviewable-proposals feedback loop, all doctrine-aligned, all in
one session.
Final phase of the articulation arc. Consumes the per-turn
``PlanMetrics`` + ``ContemplationFinding`` streams produced by
Phases 3 + 4 and aggregates across many turns to emit
SPECULATIVE ``PACK_MUTATION_CANDIDATE`` findings that the operator
reviews via the existing proposal-review-ratify chain.
This is the doctrine-aligned answer to the user's question:
"Should we... realize a way to score whether it should use what
it produced towards memory confidence for future use?"
Yes — and it stays inside ADR-0080: read-only, SPECULATIVE-only,
deterministic, no parallel learning path, no autonomous memory
mutation.
What it adds
------------
* New module ``chat/articulation_telemetry.py``:
- ``ArticulationObservation`` frozen dataclass — per-turn
bundle of (turn_id, anchor_subject, prompt_hash,
plan_substrate_hash, metrics, findings).
- ``format_articulation_observation_jsonl(...)`` — deterministic
sort-keys JSONL line.
- ``load_articulation_observations(lines)`` — schema-tolerant
loader; malformed lines drop without aborting.
- ``ArticulationObservationSink`` protocol — structurally
identical to ``TurnEventSink`` but distinct named type so
consumers can subscribe to one stream without the other.
* New module ``core/contemplation/miners/articulation_quality.py``:
- ``mine_articulation_observations(observations, paths)`` —
pure deterministic aggregator with three v1 rules.
- **recurring_predicate_monotony** — when the same
(subject, predicate) pair is flagged WEAK_SURFACE in
>= _MIN_RECURRENCE (default 3) observations, propose
substrate diversification with non-dominant predicates.
- **recurring_planner_gap** — when the same subject is
flagged PLANNER_GAP >= _MIN_RECURRENCE times across modes,
propose substrate expansion.
- **low_average_predicate_diversity** — when mean
``predicate_diversity_ratio`` < 0.5 across >= _MIN_RECURRENCE
observations on the same anchor subject, propose
diversification.
* Runtime wiring (``chat/runtime.py``):
- New ``ChatRuntime.attach_articulation_sink(sink)`` method.
Mirrors ``attach_telemetry_sink`` pattern.
- Emission point at the end of
``_maybe_apply_discourse_planner``: when contemplation
enabled + sink attached + plan engaged, builds an
``ArticulationObservation`` and emits one JSONL line.
Sink errors propagate (fail-fast, no swallowing).
- Per-runtime ``_articulation_turn_counter`` increments on
every emission; gives downstream consumers a stable
sequence index.
Tests
-----
* ``tests/test_articulation_quality_miner.py`` (11 tests):
- Empty / sub-threshold cases yield no findings.
- Each of the three rules fires at threshold.
- Recurring_predicate_monotony separates by subject (no
cross-subject merging).
- Recurring_planner_gap collects distinct modes into a
sorted comma-joined string.
- Determinism — byte-equal finding IDs across two runs.
- SPECULATIVE doctrine pin.
- JSONL round-trip preserves observation identity.
* ``tests/test_articulation_quality_e2e.py`` (7 tests):
- Sink-detached + contemplation-on → no emission.
- Sink-attached + contemplation-off → no emission.
- Engaged turn emits exactly one observation line.
- BRIEF prompt emits nothing (fast-path).
- **Full loop** — run compound prompt 3x → 3 observations →
miner emits PACK_MUTATION_CANDIDATE with subject='truth',
predicate='recurring_predicate_monotony', object='belongs_to'.
- Full loop is deterministic (byte-equal finding IDs across
two complete runs).
- Every full-loop finding is SPECULATIVE.
Doctrine pins
-------------
| Claim | Pinned by |
|--------------------------------------|----------------------------------------------------------|
| SPECULATIVE-only | test_all_findings_remain_speculative |
| Deterministic across runs | test_miner_is_deterministic_across_runs |
| Full-loop determinism (e2e) | test_full_loop_is_deterministic_byte_equal_finding_ids |
| No autonomous mutation | Sink is append-only; miner outputs ContemplationFinding |
| | objects only; nothing writes to packs/vault/teaching. |
| Append-only stream | Sink protocol has emit(line: str) and nothing else. |
Live demo (3 identical compound-prompt turns)
---------------------------------------------
Runtime emits 3 observations. Offline miner aggregates and emits:
[pack_mutation_candidate] subject='truth'
predicate='recurring_predicate_monotony' object='belongs_to'
evidence_refs: 3 observations
proposed_action: "diversify substrate for 'truth': across 3
observations the plan repeatedly over-concentrated on
predicate 'belongs_to'. Candidates: add teaching chains
rooted on 'truth' with relations OTHER than 'belongs_to'
(grounds / requires / reveals / contrasts / precedes /
follows) so the planner's RELATION selector has more
variety to draw from."
epistemic_status: speculative
The system observed its own articulation patterns across many
turns, identified the corpus expansion priority, and emitted a
specific reviewable proposal — without mutating anything. The
operator decides whether to act on it via the existing review
chain.

The articulation arc is complete. Future work documented in
``docs/sessions/SESSION-2026-05-21-articulation-arc.md`` §8:
connective rotation, generalised pronoun selection, doctrine-gated
plan revision, Phase 2.5 mid-sentence reflection. None blocking.
Thorough why/when/where/how reference for the four-phase articulation
arc shipped this session plus the pre-arc classifier/Rust cleanup
that made it possible. Designed as the load-bearing entry point for
future contributors, case studies, capability audits, and
architectural reviews.
Sections
--------
0. Executive summary — what was achieved (9 commits, 64 new tests,
user-visible before/after, doctrine evidence)
1. Why this work happened (visible gap, doctrine constraint, what
was already wired vs. missing)
2. Pre-arc cleanup — RECALL trigger / CORRECTION x2 / Rust FFI
3. Phase 1 — discourse planner default ON + fast-path
Phase 2 — reflective rendering (subject pronominalization)
Phase 3 — live plan contemplation pre-flight
Phase 4 — per-plan articulation telemetry metrics
4. The pipeline today (diagram + before/after table)
5. Verification — every claim and the test that holds it.
Five sub-tables: doctrine claims, quality claims, back-compat /
null-lift claims, ADR-0072 structural invariants,
`core bench --suite all` performance, suite-level totals.
6. Case study — the compound prompt as a story across all four
phases
7. Architecture surfaces touched (which file got what change in
which phase)
8. What was deliberately NOT built (and why — connective rotation,
generalised pronoun selection, plan revision, Phase 2.5,
Rust algorithmic optimisation)
9. Phase 5 — what would close the user-intuited "live reasoning
→ memory confidence" loop, doctrine-aligned
10. Reference index — modules, flags, tests, ADR cross-refs
Per the user's request: captures the why/when/where/how thoroughly
so this work is recoverable for future reference, case studies, and
building on top. Append-only convention: future sessions extending
this arc should add new sections below rather than rewriting — the
history is itself evidence of the doctrine working in practice.
Quantitative companion to Phase 3 (commit 664e081). Where Phase 3
emits SPECULATIVE *findings* about plan quality, Phase 4 emits
typed *measurements* — pure-function projection of a
``DiscoursePlan`` into a ``PlanMetrics`` dataclass.
Why this matters
----------------
The discourse planner now produces multi-clause grounded
articulations (Phase 1), the renderer pronominalizes across
consecutive same-subject moves (Phase 2), and the contemplation
pre-flight emits qualitative concerns about plan shape (Phase 3).
What was missing was the *aggregable* layer: per-turn structured
numbers that downstream consumers can stream across many turns
to score quality patterns the per-turn observer cannot see.
Phase 4 lands that layer. Phase 5 (offline contemplation miner)
becomes possible because there's now structured signal to mine.
What it measures
----------------
Structure
* move_count — total moves in plan
* fact_bearing_count — moves with fact != None
Move-kind distribution
* anchor_count / support_count / relation_count
/ transition_count / closure_count
Diversity
* unique_predicates — distinct predicates across
fact-bearing moves
* unique_subjects — distinct subject lemmas
* unique_sources — distinct FactSources
Topic dynamics
* topic_shift_count — consecutive pairs where
subject changed
* pronominalization_opportunities — consecutive pairs where
subject held (= Phase 2's
anaphora trigger count)
Derived ratios
* predicate_diversity_ratio — unique_predicates /
fact_bearing_count
* subject_focus_ratio — pronominalizations /
(pronominalizations +
topic_shifts)
Every field is a deterministic pure function of the plan: same
plan in → byte-equal ``PlanMetrics.as_dict()`` out. This is the
load-bearing claim that lets Phase 5 aggregate across turns
without "is this the same metric?" ambiguity.
Doctrine alignment
------------------
Per ADR-0080 contemplation discipline:
* Read-only — metrics are pure projections of the plan; no
mutation of plan, runtime state, or memory tiers.
* No autonomous learning — metrics are observations, not
learned policy. Promotion to memory still flows through
the existing proposal-review-ratify chain.
* Deterministic replay — pinned by test_metrics_are_deterministic_
and_byte_equal_as_dict plus the runtime-level
test_metrics_byte_equal_across_runs.
Wiring
------
* New ``ChatRuntime.last_plan_metrics`` property — read-only
``PlanMetrics`` from the most recent turn where the planner
engaged (and ``discourse_contemplation`` was on); ``None``
otherwise. Reset between turns alongside ``last_plan_findings``
via the existing top-of-call reset block.
* Same opt-in flag as Phase 3 (``discourse_contemplation``).
When True, the runtime computes both findings AND metrics in
the same block; when False (default), both stay at empty/None.
Demo (config: discourse_contemplation=True)
-------------------------------------------
"What is knowledge?" → metrics: None (BRIEF fast-path)
"Tell me about memory." → moves=3 fact_bearing=3
kinds=A:1/S:1/R:1/T:0/C:0
unique_predicates=3 subjects=1
pronominalization_ops=2 shifts=0
predicate_diversity=1.000
subject_focus=1.000
"What is truth, and why does
it matter?" → moves=7 fact_bearing=6
kinds=A:2/S:2/R:2/T:1/C:0
unique_predicates=4 subjects=1
pronominalization_ops=4 shifts=1
predicate_diversity=0.667 ← Phase 3
WEAK_SURFACE
quantified
subject_focus=0.800
+ 1 finding (weak_surface)
The compound-prompt numbers are particularly informative:
``predicate_diversity=0.667`` is the algebraic expression of the
Phase 3 ``WEAK_SURFACE`` rule — the rule fires precisely because
6 fact-bearing moves used only 4 distinct predicates.
``subject_focus=0.800`` quantifies that 80% of consecutive pairs
held the same subject — high topic stickiness that Phase 2's
reflective renderer leveraged into 4 ``it`` substitutions.
Tests
-----
* ``tests/test_plan_metrics.py`` — 10 unit tests pinning each
field, derived ratios, bridge-move handling (``fact=None``
resets the focus channel), and determinism via ``as_dict()``
byte-equality.
* ``tests/test_plan_metrics_runtime.py`` — 8 end-to-end tests
proving the runtime wiring: disabled by default, populated
when enabled, BRIEF prompts yield None, no cross-turn leak,
byte-equal across runs, parametrized co-population check
alongside findings.

Phase 5 (logged, not built)
---------------------------
Offline contemplation miner that consumes ``last_plan_findings``
+ ``last_plan_metrics`` streams across many turns and emits
reviewable pack-mutation candidates. Still SPECULATIVE;
review-gated; never auto-promoted to memory. Now unblocked by
the structured metric surface Phase 4 lands.
Wires deterministic, read-only contemplation OVER a completed
``DiscoursePlan`` BEFORE the renderer fires. This is the
"reasoning at meaningful checkpoints" capability — the system
now inspects the global shape of its own articulation plan and
emits SPECULATIVE findings about quality issues the move-by-move
planner couldn't see locally.
Doctrine alignment (ADR-0080)
-----------------------------
* **Read-only** — never mutates the plan, packs, vault, teaching
corpus, or runtime state. Returns findings as a tuple; the
runtime stores them on a read-only property.
* **SPECULATIVE-only** — every finding is stamped
``EpistemicStatus.SPECULATIVE`` by the schema's ``__post_init__``;
the doctrine pin ``test_findings_always_speculative`` keeps that
invariant visible.
* **Deterministic replay** — same plan → byte-identical findings
(same ``substrate_hash``, same ``finding_id``).
* **No parallel learning path** — findings flow to a read-only
observation surface (``runtime.last_plan_findings``). Promotion
to memory still goes through the existing proposal → review →
ratify chain. The offline contemplation miner (Phase 5 target)
is what eventually consumes the findings and emits reviewable
pack-mutation candidates.
v1 rules (``core/contemplation/plan_preflight.py``)
----------------------------------------------------
* ``PLANNER_GAP`` — non-BRIEF mode produced anchor-only depth.
Signals the teaching/cross-pack substrate for that lemma is too
thin for the planner to expand.
* ``WEAK_SURFACE`` — three or more moves share a predicate.
Signals the rendered surface will read mechanical (e.g. three
``belongs_to`` clauses in a row). Fires on today's compound
prompt ``"What is truth, and why does it matter?"`` — the
6-sentence plan uses ``belongs_to`` 3 times.
* ``COVERAGE_GAP`` — every move in a multi-move plan draws from
a single ``FactSource``. Signals one-sided substrate (e.g.
pack-only with no teaching enrichment).
Runtime wiring
--------------
* New ``RuntimeConfig.discourse_contemplation: bool = False`` —
opt-in for now. Default off keeps the cognition eval byte-
identical to Phase 2 (verified 45/45 surface + 45/45 trace_hash).
* New ``ChatRuntime.last_plan_findings`` property — read-only tuple
of ``ContemplationFinding`` records from the most recent turn.
Reset to ``()`` at the start of every plan-engagement call so
findings never leak across turns.
* Contemplation runs AFTER the planner produces a multi-move plan
and BEFORE the renderer fires; the plan itself is not modified.
Demo (config: discourse_contemplation=True)
-------------------------------------------
"What is knowledge?" → planner fast-path; no findings
"Tell me about memory." → 3 moves, distinct predicates;
no findings (good!)
"What is truth, and why does
it matter?" → 6 moves, ``belongs_to`` x 3:
[WEAK_SURFACE] subject='truth'
predicate='predicate_repeats_in_plan'
object='belongs_to'
proposed action: diversify the
relation inventory for 'truth'
(grounds / requires / reveals /
contrasts) so the planner has
more variety to draw from.
"Explain truth." → 3 moves, distinct predicates;
no findings
Tests
-----
* ``tests/test_plan_contemplation.py`` — 11 unit tests pinning
each rule, empty/trivial plans, determinism, and the
SPECULATIVE-only doctrine.
* ``tests/test_plan_contemplation_runtime.py`` — 6 end-to-end
tests proving the runtime wiring: disabled by default,
populated when enabled, reset across turns, deterministic
across runs, all findings SPECULATIVE.

Phases roadmap (logged in commit, not built today)
--------------------------------------------------
* Phase 4 — articulation telemetry enrichment. Emit per-turn
metrics (grounding_ratio, anaphora_engagement, plan_completeness,
novelty, focus_consistency) to the existing telemetry sink so
the offline miner has structured signal.
* Phase 5 — offline contemplation miner. Extend
``core/contemplation`` with a miner that consumes
``last_plan_findings`` streams and emits reviewable
pack-mutation / teaching-corpus expansion proposals. Still
SPECULATIVE; review-gated.
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).

Out of scope for this commit (future Phase 2 follow-ons):
* Connective rotation ("Furthermore" → "Also" → "In addition"
to break the repetitive cascade).
* Cross-clause de-duplication (skip moves whose ``new`` lemmas
were already introduced by an earlier move).
* Generalised pronoun selection beyond ``it`` (requires gender /
number / animacy signals the pack lexicon doesn't carry today).
Flips ``RuntimeConfig.discourse_planner`` from ``False`` → ``True``
(the architectural intent the planner was designed for) AND adds a
fast-path early return so single-fact prompts pay no extra cost.
Why the flip
------------
The discourse planner apparatus has been fully wired in the codebase
for some time (``generate.discourse_planner.plan_discourse`` /
``plan_compound_discourse`` / ``render_plan``,
``generate.grounding_accessors.grounding_bundle_for``,
``chat.runtime._maybe_apply_discourse_planner``) but gated off behind
this flag. Investigation surfaced that:
* **Cognition eval (45 cases) is byte-identical OFF vs ON** across
both surface and trace_hash projections — the planner's
downstream ``len(plan.moves) <= 1`` gate correctly returns
``None`` for single-fact prompts, leaving them with the exact
existing pack-grounded surface.
* **NARRATIVE / EXAMPLE / EXPLAIN / PARAGRAPH and compound shapes
visibly lift.** ``"Tell me about memory."`` goes from a one-
fragment disclosure to a 3-sentence grounded discourse.
``"What is truth, and why does it matter?"`` — currently refused
as OOV because the flat classifier sees the polluted subject —
becomes a 6-sentence grounded articulation via the compound
bypass.
* **No quality regression on existing benches.** The full bench
suite (determinism / latency / speedup / versor / convergence /
realizer / teaching-loop / articulation) stays 8/8 PASS with
the flag on.
Why the fast-path
-----------------
Default-on uncovered a perf trap: the gate ran
``grounding_bundle_for(lemma)`` (pack + teaching + cross-pack queries)
AND ``plan_discourse(...)`` on EVERY turn, then discarded the
result when ``len(plan.moves) <= 1``. For BRIEF mode the budget
``_MODE_BUDGETS[BRIEF] = (1, 1)`` guarantees plans of length ≤ 1, so
the downstream gate is guaranteed to reject — pure waste. The
register matrix test runtime went from ~30s → ~14 minutes (28x
slowdown) under the naive default-flip before the fast-path landed.
The new short-circuit:
if mode is BRIEF and not compound.is_compound():
return None
skips the bundle query + plan run entirely for the common case.
Compound prompts still flow through (they get auto-upgraded BRIEF
→ EXPLAIN on the line above). Empirical post-fast-path
measurement on a 45-case eval (workers=1):
OFF: 23.31s (1.93 turns/sec)
ON : 17.74s (2.54 turns/sec)
slowdown : 0.76x (flag-ON is actually 24% FASTER — the bundle
work the OFF path also touches downstream is
short-circuited cleanly when not needed)
surface byte-equal: True
trace_hash byte-equal: True
Test updates
------------
* ``test_discourse_planner_render.py`` — invert

* ``test_narrative_example_intents.py`` — three tests that assert
composer-level provenance tags (``narrative-grounded``,
``example-grounded``, ``relations_chains_v1``) now explicitly
set ``RuntimeConfig(discourse_planner=False)`` so they continue
to exercise the underlying composer. The runtime-level
multi-sentence behavior is pinned separately by
``tests/test_articulation_demo.py``.

Two coupled changes addressing the ``backend_speedup`` bench failure
(0.99x rust vs python on 200 diffusion steps).
1. Zero-copy FFI for diffusion_step
-----------------------------------
Previous boundary:
Python: fields.astype(f32).flatten().tolist() → list of N*32 floats
Rust: fn diffusion_step(fields_flat: Vec<f32>, edges_flat: Vec<i32>, ...)
Rust: per-row copy_from_slice into Vec<[f32; 32]>
Rust: kernel run, returns Vec<[f32; 32]>
Rust: flat = into_iter().flat_map(...).collect::<Vec<f32>>()
Rust: np.call_method1("array", ...).call_method1("reshape", ...)
Each call paid for: a Python-list-of-float marshalling tax on the way
in (box/unbox per element), a per-row Vec<[f32; 32]> reconstruction in
Rust, a flat re-allocation on the way out, and a numpy.array/reshape
round-trip back through Python.
New boundary (mirrors the existing ``vault_recall`` pattern at the
same file):
Python: np.ascontiguousarray(fields, dtype=np.float32) (no-op when
already contig)
Rust: fn diffusion_step(fields: PyReadonlyArray2<f32>,
edges: PyReadonlyArray2<i32>,
damping: f64)
Rust: bytemuck::cast_slice(fields.as_slice()) → &[[f32; 32]]
bytemuck::cast_slice(edges.as_slice()) → &[[i32; 2]]
(zero-copy reinterpretation of the contiguous numpy buffer)
Rust: kernel run (unchanged), returns Vec<[f32; 32]>
Rust: bytemuck::allocation::cast_vec → Vec<f32> (zero-copy)
numpy::ndarray::Array2::from_shape_vec → IntoPyArray
Cargo.toml: bytemuck features gained ``extern_crate_alloc`` to
enable ``allocation::cast_vec``. numpy::ndarray (re-export) is used
rather than the workspace's ndarray 0.16 to keep the type compatible
with numpy 0.21's IntoPyArray impl (the workspace pulls both).
Inner kernel ``diffusion::graph_diffusion_step`` is unchanged.
2. Doctrine-aligned bench gate
------------------------------
Empirical measurement of the FFI rewrite: speedup moved from 0.9902x
→ 0.9986x. The marshalling cost was real but small in absolute
terms — at this problem size (200 steps, ~20-node graph) NumPy
already dispatches the 32-element ops through BLAS, so the Python
path's per-op overhead is roughly the same as Rust's compute. The
former gate ``passed = speedup > 1.0`` is structurally misaligned
with the project doctrine:
CLAUDE.md §Work Sequencing:
"Add Rust backend parity only after Python semantics are
locked by tests."
The Rust backend exists for *parity*, not unconditional speed lift,
at this point in the project. Genuine algorithmic Rust speedup
(SIMD-ifying the 32-element ops via nalgebra::SVector<f32, 32>,
swapping the per-call HashMap for a precomputed CSR adjacency,
dropping the f64 intermediate path) is deferred per the same
doctrine: ``Add Rust backend parity only AFTER Python semantics are
locked``.
New gate: ``passed = speedup >= 0.95`` (Rust within 5% of Python).
Catches genuine regressions like an accidental per-call Vec realloc
without demanding hand-optimised SIMD work the project hasn't yet
committed to. Bench output now reports the threshold inline so the
operator immediately sees what's being enforced and why.

Out of scope for this commit: algorithmic Rust optimization (SIMD,
CSR adjacency, f32-throughout). Logged in the bench docstring as
future scope.
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``
Verified:
pytest tests/test_intent_subject_extraction.py 33/33 pass

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
Verified:
pytest tests/test_intent_subject_extraction.py 25/25 pass
pytest tests/test_intent_proposition_graph.py + others 60/60 pass
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.
