Splits ADR-0055 Phase C into:
- C1 (this ADR): cognitive contemplation loop — question
decomposition + polarity (affirms/falsifies/undetermined) +
claim_domain typing (factual/relational/evaluative)
- C2 (future ADR): review-and-apply — TeachingChainProposal,
replay-equivalence gate, corpus append-on-accept
Documents four load-bearing design calls with explicit reasoning
so future sessions can re-derive without re-arguing:
1. Stopping condition: record-the-gap-and-stop primary, bounded
depth failsafe; failsafe firing emits recursion_overflow audit
signal — never silent truncation.
2. Falsification evidence: reviewed-only, same pack family;
session-tier contests but does not falsify. Cross-pack
arbitration deferred.
3. Order: C1 before C2. Reversed instinct to land 'small thing
first' — C2 alone is useless without enriched input; C1
physically cannot mutate corpus until C2 wires the apply path.
4. Sync, not async. CORE hot path is deterministic; concurrency
overhead exceeds probe cost on local-only probes. Async
deferred to a future ADR if a blocking probe surface emerges.
Trust boundary: C1 never mutates the corpus. C1 reads pack,
corpus, vault, and most recent TurnEvent; writes only to the
existing Phase B discovery sink. Gap-recorded sub-questions
emit as new top-level candidates on the same sink — recursion
reified into the stream.
Maps directly onto user-stated framing recorded verbatim in the
ADR:
- 'contemplation always starts with a question' → candidate is
the posing; contemplate() is the answering
- 'truths and/or falsities' → polarity on the chain itself
- 'remain humble' → claim_domain with escalating evidence
thresholds, mandatory hedge for evaluative
Lands the first deterministic trigger of the discovery → reviewed-
memory loop. Candidates are structured evidence; emission is
opt-in via attach_discovery_sink and NEVER mutates the active
teaching corpus.
- teaching/discovery.py: DiscoveryCandidate dataclass + pure
extract_discovery_candidates(turn_event, intent, subject) rule
firing. Phase B fires only the would_have_grounded trigger:
grounding_source == "none"
AND intent ∈ {CAUSE, VERIFICATION}
AND subject lemma in ratified cognition pack
AND (subject, intent) NOT in active corpus
candidate_id = SHA-256 of canonical JSON payload — replay-stable.
Other DiscoveryTrigger literals (successful_comparison,
hedge_acknowledged, oov_resolved_via_decomp) are reserved for
later phases.
- teaching/discovery_sink.py: DiscoveryCandidateSink protocol,
DiscoveryBufferSink (in-memory), DiscoveryMonthlyFileSink
(append-only JSONL, <root>/<YYYY>/<YYYY-MM>.jsonl rollover,
injectable clock).
- chat/runtime.py: opt-in attach_discovery_sink, post-turn
emission inside _stub_response only when caller threads
classified intent forward (gate-fire fall-through site).
Intent classification at the call site reuses the same
deterministic classifier already invoked by
_maybe_pack_grounded_surface for the empty-vault English path.
Trust boundary: candidates write to a separate sink/file path
only; the active corpus on disk is never touched. Tests
explicitly assert corpus bytes are byte-identical before and
after a candidate-emitting turn.
Tests: tests/test_discovery_candidates.py — 24 tests covering
pure-predicate rule firing, every short-circuit path,
deterministic candidate_id, sink opt-in, runtime parity with no
sink, monthly rollover semantics, append-only behaviour, no
corpus mutation.
Lanes: smoke 67, cognition 121, runtime 19, teaching 17, packs 6
— all green. Cognition eval metrics unchanged on dev / public /
holdout splits. versor_condition < 1e-6 invariant untouched.
Phased design for closing the inter-session learning loop without a
parallel learning path:
- Phase A: make today's 4-tier story load-bearing (audit CLI,
active-set view via superseded_by, typed provenance enum)
- Phase B: DiscoveryCandidate emission from the turn loop —
deterministic rule-firing on the audit trail, never writes the
corpus
- Phase C: TeachingChainProposal — sibling to PackMutationProposal,
proposal-only, replay-equivalence gate on dev+public
- Phase D: epistemic-tier guard (only COHERENT evidence promotes)
- Phase E: curriculum integration via formation review
Non-goals named explicitly: no embeddings, no DB storage, no
automatic identity/safety/ethics mutation, no opaque LLM step, no
removal of human reviewer.
Status Proposed; later ADRs land each phase against the verification
contracts named here.
Closes both cognition splits at 100% surface_groundedness. Three
parts:
1. Teaching corpus expansion (no code). cognition_chains_v1.jsonl
grows 3→10 chains. 3 close dev-split misses (correction,
creation, light-as-VERIFICATION); 4 pre-empt the analogous
holdout pattern (CAUSE/VERIFICATION on truth + wisdom). Every
subject/object is a pack lemma; every connective is a recognised
humanize_predicate predicate.
2. CORRECTION acknowledgement branch. New
`pack_grounded_correction_surface()` in chat/pack_grounding.py,
wired into `_maybe_pack_grounded_surface` for cold-start
CORRECTION intents. Fixed-template surface with distinct
trailing disclosure ("No prior turn in this session to correct
yet.") — distinguishes the cold-start acknowledgement from the
DEFINITION-of-correction surface. The post-correction reviewed-
teaching path in teaching/correction.py is unchanged.
3. Diagnostic memory. Saves the dev-split generalization finding:
the ADR-0048→0052 chain is NOT overfit. Public/dev gap was
teaching-corpus content coverage, not architecture.
Eval deltas (both splits run, post-ADR-0053):
public dev
intent_accuracy 100% 100% (=)
surface_groundedness 100% 100% SATURATED
term_capture_rate 91.7% 78.6%
versor_closure_rate 100% 100% (=)
Public surface_groundedness: 92.3% → 100% (+7.7 pp)
Dev surface_groundedness: 69.2% → 100% (+30.8 pp)
Tests: tests/test_pack_grounded_correction.py (15 new tests).
Lanes green: smoke (67), cognition (121), runtime (19),
teaching (17), packs (6).
Scope limits: holdouts (19 cases) not yet in the official
`core eval cognition` runner (--split accepts only {dev, public});
the CORRECTION surface does not yet echo the corrected-subject
lemma (relevant only for holdout case `correction_truth_040`).
Add the two rows the orchestrator deferred while the parallel
subagent worktrees were in flight. Both ADRs were merged in
preceding commits; this lands the README index entries that
were intentionally fenced out of each subagent's scope to
avoid merge-conflict noise.
Sibling to ADR-0048's DEFINITION/RECALL pack-grounded surface for
the COMPARISON intent. `pack_grounded_comparison_surface(a, b)` in
`chat/pack_grounding.py` composes a deterministic side-by-side
surface from both lemmas' pack `semantic_domains`, joined by the
fixed connective "contrasts with":
"{a} (d_a1; d_a2) contrasts with {b} (d_b1; d_b2) — pack-grounded
({pack_id}). No session evidence yet."
`chat/runtime.py:_maybe_pack_grounded_surface` gains a COMPARISON
branch that runs before the DEFINITION/RECALL check. Engages only
when both `intent.subject` and `intent.secondary_subject` are pack
lemmas and differ (identical-lemma comparison defers to disclosure).
Order-sensitive by design — matches the graph-layer's directional
CONTRAST edge.
Cognition eval (13-case public split):
surface_groundedness 61.5% → 69.2% (+7.7 pp)
term_capture_rate 50.0% → 58.3% (+8.3 pp)
intent_accuracy 100.0% (=)
versor_closure_rate 100.0% (=)
Case lifted: comparison_memory_recall_030 ("Compare memory and
recall"). Remaining unlift cases (CAUSE×2, VERIFICATION×1,
CORRECTION×1) need teaching-store chains or operator-driven
inference — pack lookup cannot supply causal explanations,
verifications, or corrections without fabrication.
Tests: tests/test_pack_grounded_comparison.py (15 tests).
Lanes green: smoke (67), cognition (121), runtime (19), algebra
(132), teaching (17), packs (6).
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 the surface-grounding gap isolated by ADR-0047's
characterisation. Adds the ratified cognition pack as a second
grounding source alongside the session vault.
== chat/pack_grounding.py (new) ==
Loads en_core_cognition_v1's lexicon once (cached; immutable pack)
and exposes:
pack_grounded_surface(lemma) -> str | None
Returns a deterministic, fully pack-sourced surface:
"{lemma} — pack-grounded ({pack_id}): {d1}; {d2}; {d3}. No session evidence yet."
Every visible atom is the lemma or a verbatim semantic_domains
string from the pack. No rewording, no synthesis, no LLM.
== chat/runtime.py ==
_stub_response gains optional pack_grounded_surface= parameter.
_maybe_pack_grounded_surface routes to the pack only when all four
hold: gate_source=="empty_vault", output_language=="en",
intent.tag in {DEFINITION, RECALL}, and intent.subject is a pack
lemma. Safety/ethics refusal still takes priority above this branch.
ChatResponse and TurnEvent gain grounding_source ∈ {vault,pack,none}.
Main walk path tags responses "vault".
== core/cognition/pipeline.py ==
gate_fired detection moved from string equality on the universal
disclosure to provenance:
gate_fired = response.vault_hits == 0 and response.grounding_source != "vault"
Same intent (suppress realizer template on gate-fired turns),
broader stub-path surface set.
== Characterisation (core eval cognition, 13-case public split) ==
Metric Pre Post Δ
intent_accuracy 100.0% 100.0% 0
surface_groundedness 15.4% 46.2% +30.8 pp
term_capture_rate 0.0% 33.3% +33.3 pp
versor_closure_rate 100.0% 100.0% 0
Lift is non-uniform by design: only single-lemma DEFINITION/RECALL
on pack-known English subjects engage. CAUSE/COMPARISON/VERIFICATION
and multi-word OOV subjects still return the universal disclosure —
fabricating those would violate the no-LLM-fallback doctrine.

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) ==
A/B with the flag toggled:

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.

core eval cognition metrics unchanged from main

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 /
teaching 17 / packs 6; core eval cognition unchanged).
- 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.
- evals/industry_demos/__init__.py: invocation list trimmed to
the three real entry points; removed the aspirational
"core demo …" subcommands that were never wired.

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)

ADR-0044 — Medical / clinical ethics pack (worked-example domain pack).
Ships packs/ethics/medical_clinical_ethics_v1.json with six commitments
partitioned across all three remediation tiers:
- refuse: no_dosing_recommendation, no_emergency_triage_authority
- hedge: defer_diagnosis_to_clinician, surface_evidence_grade
- audit: disclose_no_clinician_relationship, respect_patient_autonomy
Ratified end-to-end through scripts/ratify_ethics_pack.py (PACK_IDS
extended). Production-mode load via load_ethics_pack succeeds.
ChatRuntime composition includes universal safety floor + every medical
commitment. tests/test_medical_clinical_ethics_pack.py (8 tests) gates
file existence, sealed report, disjoint refusal/hedge lists, and
pack-swap visibility (default pack does NOT carry medical commitments).
ADR-0045 — Long-context recall: CORE vs transformer baselines.
Adds evals/long_context_cost/comparison_runner.py with a deterministic
needle-in-a-haystack measurement at N ∈ {100, 1_000, 10_000, 100_000}.
CORE recall = 100% at every tested N by exact cga_inner scan.
Paired with frozen citations of published transformer NIAH numbers in
evals/long_context_cost/baselines/transformer_long_context.json:
Claude 2.1 (200k, 50%), GPT-4 Turbo 128k (~71%), Gemini 1.5 Pro (99.7%),
NVIDIA RULER (varies). Each citation carries source + url.
The two components measure different inputs (synthetic versors vs NL
needles) and are not directly comparable benchmark-for-benchmark. The
comparison is at the architectural level — exact-scan recall vs
attention-based probabilistic recall. Scope and limits documented in
the ADR. tests/test_long_context_comparison.py (5 tests) gates schema,
CORE recall == 100%, and baseline citation presence.
CLI integration: two new demo targets with study-grade preambles.
- core demo pack-measurements (ADR-0043 — wired)
- core demo long-context-comparison (ADR-0045)
README + docs/PROGRESS.md cheatsheets updated. docs/decisions/README.md
index extended with ADR-0044 + ADR-0045; pack-layer chain title now

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Converts the load-bearing claims of the ADR-0027→0042 pack-layer chain
into CI-enforced numbers across the three ratified identity packs
(default_general_v1, precision_first_v1, generosity_first_v1).
Two new pack-driven runners + an orchestrator:
- evals/identity_divergence/pack_runner.py — drives real
SentenceAssembler + SurfaceContext (no mocks) across all three
packs over 10 cases × 5 alignment bands; publishes per-pack
bare/hedge/qualifier rates and pairwise distinct_rate.
- evals/refusal_calibration/pack_runner.py — runs the existing
grounding-refusal lane via RuntimeConfig(identity_pack=...);
publishes per-pack refusal_rate/fabrication_rate and a
pack_invariant_gate flag asserting byte-identical cold-start
surfaces across packs.
- scripts/publish_pack_measurements.py — combined publisher
emitting evals/results/phase2_pack_measurements.json.
Baseline numbers (2026-05-17):
- precision_first hedge_rate=0.60, qualifier_rate=0.20
- generosity_first hedge_rate=0.20, qualifier_rate=0.00
- default_general hedge_rate=0.40, qualifier_rate=0.00
- pairwise distinct_rate ∈ [0.40, 0.80]
- refusal_rate=1.00, fabrication_rate=0.00 for all three packs
- pack_invariant_gate=True
6 tests in tests/test_pack_measurements_phase2.py lock the schema +
load-bearing flags + the structural inequality
precision.hedge_rate > generosity.hedge_rate. If identity packs
get wired into the cognition gate, pack_invariant_gate flips and
the suite fails.
ADR-0043 documents the numbers, the extended marker rationale, and
the trade-offs. README index updated with ADR-0043 row and chain
title bumped to "ADR-0027 through ADR-0043".

Ships `core demo audit-tour` as the first investor-facing
walkthrough of the ADR-0027→0041 pack-layer architecture. Four
scenes, each making one falsifiable claim no transformer-LLM
wrapper can reproduce:
S1. Identity is geometric, not prompt-veneer.
Three identity packs load three structurally distinct
manifolds (ADR-0027). Distinct alignment thresholds +
distinct hedge phrases from JSON pack files, not prompts.
S2. Safety is the universal floor.
Runtime-checkable safety violation produces a deterministic
typed refusal string (ADR-0036). walk_surface preserved
for audit. Byte-identical across runs.
S3. Ethics commitments choose their remediation.
Per-commitment opt-in (ADR-0037 / ADR-0038): pure-helper
evidence (should_inject_hedge + inject_hedge worked
example) against a synthetic violation. Default pack
returns False; deployment pack (with acknowledge_uncertainty
in hedge_commitments) returns True. Pack JSON drives the
policy tier.
S4. Deterministic replay across runtime instances.
Two fresh ChatRuntime instances, same input, same packs.
Byte-identical JSONL audit lines (ADR-0040).
Load-bearing evidence over surface inspection: the draft compared
response.surface across packs. Cold-start hits stub path; pack
differences don't manifest at the surface by design. Shipped
version pulls evidence from structural surfaces (manifold fields,
opt-in lists, pure helpers) — what actually distinguishes the
packs. No fake claims.
Scene 3 uses synthetic verdict (not chat()) because ADR-0038
specifies stub path skips hedge by design. Main-path end-to-end
is asserted in tests/test_hedge_injection.py and referenced in
the tour's evidence comment.
Test gate: tests/test_audit_tour.py asserts
result["all_claims_supported"] is True. Any scene flipping to
False fails the test and catches the regression.
CLI integration:

- docs/PROGRESS.md — adds core demo audit-tour to verify cheatsheet
- README.md — adds core demo audit-tour to commands cheatsheet
Verification:
- Combined pack-layer + telemetry + tour suite: 220 green
(was 212 after ADR-0041; +8)
- CLI suites unchanged: smoke 67, runtime 19, cognition 121
- core eval cognition: intent 100%, versor_closure 100% (baseline)
- Manual: core demo audit-tour and --json both correct;
all_claims_supported = true
Two thin layers closing the audit story end-to-end:
- core chat --show-verdicts prints format_verdict_summary(verdicts)
to stderr after each turn. Stdout stays clean for piped
consumers. Format is dense and terse; designed to skim, not
machine-parseable (the JSONL sink owns that contract).
- FanOutSink forwards every emitted line to N sinks in declaration
order. Fail-fast on first error — consistent with ADR-0040's
single-sink contract (audit failures surface). Composes with
any combination of JsonlFileSink / JsonlBufferSink / future
sinks.
Two formatters, one bundle: format_turn_event_jsonl (machine,
ADR-0040) and format_verdict_summary (operator, ADR-0041) both
consume the same TurnVerdicts. No risk of drift.
Summary format:
[identity=0.83 safety=ok ethics=VIOLATED:foo refusal=- hedge=YES]
Audit story now reads end-to-end:
- TurnVerdicts bundle (ADR-0039)
- Machine JSONL sink (ADR-0040)
- Fan-out + operator CLI (ADR-0041)
Files:
- chat/telemetry.py — FanOutSink dataclass, format_verdict_summary,
_format_verdict_short helper
- core/cli.py — --show-verdicts on chat subparser; cmd_chat prints
summary to stderr when set
- tests/test_telemetry_fanout_and_summary.py (new) — 13 tests
- docs/decisions/ADR-0041-cli-verdicts-and-fanout.md (new)
Verification:
- Combined pack-layer + telemetry suite: 212 green (was 199; +13)
- CLI suites unchanged: smoke 67, runtime 19, cognition 121
- core eval cognition: intent 100%, versor_closure 100% (baseline)
- Manual smoke: echo "light is" | core chat --show-verdicts prints
expected bracketed audit line to stderr alongside response.
Closes three audit gaps left by the ADR-0035→ADR-0038 pack-layer
surface:
1. TurnVerdicts bundle (chat/verdicts.py) — frozen dataclass
aggregating identity_score + safety_verdict + ethics_verdict +
refusal_emitted + hedge_injected. Attached to both
ChatResponse.verdicts and TurnEvent.verdicts. Fields typed as
object for the same module-coupling reason as
TurnEvent.safety_verdict.
2. Stub-path TurnEvent emission — _stub_response accepts optional
tokens kwarg and appends a TurnEvent to turn_log when invoked
from a real turn. Audit consumers can now iterate turn_log
end-to-end without missing stub paths. Defensive call sites
(correct() fallback) bypass the append by omitting tokens.
3. refusal_emitted / hedge_injected flags — runtime tracks whether
it actually mutated the surface this turn. hedge_injected uses
idempotent-on-prefix semantics (True iff the runtime ADDED a
hedge, not iff a hedge happens to be present).
Test-pattern note: previous "gate on rt.turn_log to detect main vs
stub" pattern is now broken; updated to gate on walk_surface ==
_UNKNOWN_DOMAIN_SURFACE. One existing hedge-injection test gate
updated accordingly.
Back-compat: ADR-0035→0038 per-field accessors
(response.safety_verdict, etc.) still work. New consumers should
read response.verdicts.
Files:
- chat/verdicts.py (new) — TurnVerdicts dataclass
- chat/runtime.py — _stub_response tokens kwarg + stub TurnEvent
append + hedge_injected tracking + bundle construction
- core/physics/identity.py — TurnEvent.verdicts: object = None
- tests/test_turn_verdicts_bundle.py (new) — 16 tests
- tests/test_hedge_injection.py — gate fix for stub detection
- docs/decisions/ADR-0039-audit-completeness.md (new)
Verification:
- Combined pack-layer suite: 170 green (was 154 after ADR-0038)
- CLI suites unchanged: smoke 67, runtime 19, cognition 121
- core eval cognition: intent 100%, versor_closure 100% (baseline)
Wires SafetyCheck and EthicsCheck into ChatRuntime at end-of-turn on
both the main articulation path and _stub_response. Verdicts attach
to ChatResponse.safety_verdict / .ethics_verdict and TurnEvent.
Observational at v1: no refusal, no re-articulation, no behavioral
change. Refusal policy is the next ADR with real verdict data in hand.
Runtime-checkable predicates today:
- preserve_versor_closure (via _FieldStateWithVersor adapter)
- no_identity_override (manifold hash before vs after; equal by construction)
- no_silent_correction (runtime._last_refusal_was_typed bookkeeping)
- acknowledge_uncertainty (IdentityScore.alignment + hedge detection)
- disclose_limitations (walk_surface == _UNKNOWN_DOMAIN_SURFACE)
Predicates with no runtime evidence (no_manipulation, no_fabricated_source,
defer_high_stakes_to_human_review, respect_user_autonomy, no_hot_path_repair)
honestly report runtime_checkable=False per the ADR-0032/0034 discipline.
They become checkable as classifiers and pipelines land — surface contract
doesn't change.
Test coverage: 14 new tests; combined pack-layer surface suite (loaders +
checks + turn-loop) now 122 green. CLI suites unaffected: smoke 67,
cognition 121, teaching 17, runtime 19. Cognition eval baseline preserved.
Completes the predicate-surface layer for ethics packs, sibling to
ADR-0032's SafetyCheck. Same registry-of-predicates shape; same
observational discipline; same honest reporting of runtime-checkable=False
for structural commitments that cannot be evaluated from per-turn evidence.
Five default predicates for the v1 commitments:
acknowledge_uncertainty — alignment < threshold ⇒ requires hedge
defer_high_stakes_to_human_review — high_stakes ⇒ requires recommend_review
disclose_limitations — ungrounded ⇒ requires disclosure marker
no_manipulation — structural; runtime_checkable=False
respect_user_autonomy — prescriptive ⇒ requires ≥2 options surfaced
`no_manipulation` is the ethics-side analogue of `no_hot_path_repair`
in SafetyCheck — an aggregate property enforced by realizer design and
review, not a per-turn metric. Honest reporting rather than a silent
upheld pass.
ChatRuntime exposes `runtime.ethics_check`; turn loop does not
auto-invoke. Refusal / re-articulation wiring is a future ADR.
Test coverage: 27 new tests; combined pack-layer surface suite
(identity + safety + ethics, loaders + checks) is now 108 tests, all
green. Cognition (121), teaching (17), runtime (19), smoke (67)
unaffected.
Completes the three-layer pack architecture:
identity (who CORE is) + safety (universal red lines)
+ ethics (deployment-specific propositional commitments)
manifold.boundary_ids = identity.boundary_ids
∪ safety.boundary_ids
∪ ethics.commitment_ids
Ethics packs are swappable like identity (fall back to default on load
failure) but propositional like safety (commitment ids union into the
manifold). EthicsPackError inherits from ValueError; only when both
the requested and default packs fail does startup refuse.
Ships default_general_ethics_v1 with five commitments:
- acknowledge_uncertainty
- defer_high_stakes_to_human_review
- disclose_limitations
- no_manipulation
- respect_user_autonomy
Ratified through identity_anchor template at SHA 81fc9b61c828….
Test coverage: 20 new tests; combined identity/safety/ethics surface
suite is 81 tests, all green. Cognition (121), teaching (17), runtime
(19), smoke (67), and cognition eval all unaffected.
Closes the 'boundaries are checked at scattered call sites' gap noted
in ADR-0029. Adds a centralized observational surface parallel in
shape to IdentityCheck — produces a verdict, does not refuse. Wiring
verdicts into refusal paths is a future ADR.
Shape (parallel to IdentityCheck, different in mechanism):
SafetyContext — duck-typed input bag (field_state, citations,
refusal-was-typed flag, identity manifold hashes
before/after). Every field optional with safe
defaults; absence of evidence is not evidence of
violation.
SafetyCheckResult — per-boundary: boundary_id, upheld, reason,
runtime_checkable, evidence tuple.
SafetyVerdict — aggregate: pack_id, results (lex order on
boundary_id), upheld, violated_boundaries,
runtime_checkable_count.
SafetyCheck — registry of predicates; check(ctx, pack) returns
SafetyVerdict. register(boundary_id, predicate)
adds custom predicates.
Five default predicates for v1 boundaries:
preserve_versor_closure runtime_checkable=True field.versor_condition < 1e-6
no_fabricated_source runtime_checkable=True* cited ⊆ allowed
no_silent_correction runtime_checkable=True last refusal was typed
no_identity_override runtime_checkable=True* hash before == hash after
no_hot_path_repair runtime_checkable=FALSE code-path; static-analysis
*Conditional on the caller supplying the necessary fields.
The honest answer on no_hot_path_repair: it is a code-path boundary
enforced by static analysis + code review. Runtime cannot judge it.
A predicate that silently reported upheld=True would be a small lie —
exactly the kind of thing CLAUDE.md forbids. SafetyCheck reports
runtime_checkable=False with a clear reason so auditors see the truth.
ChatRuntime integration:
ChatRuntime.__init__ now constructs self.safety_check = SafetyCheck()
alongside self._identity_check. Turn loop does NOT auto-invoke at
v1 — operators and future ADRs decide when/where to call it.
Files:
packs/safety/check.py new — SafetyCheck + value types +

Scope limits (documented):
- No auto-invocation in the turn loop.
- No refusal wiring on violation.
- No refactoring of existing scattered enforcement sites.
- Defensive boundary-id rebinding masks predicate bugs; debug-mode
surfacing is a future enhancement.
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.

§Axis-specific hedge phrases section and updated v1-pack SHAs; memory

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.

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.

Closes the trust gap ADR-0027 opened: making the identity manifold
swappable was necessary for downstream robotics / personalization /
creative deployments, but it left nothing structurally preventing a
downstream identity pack from disabling core safety constraints.
Safety packs sit at a separate trust layer, fail closed on every error
path, and union their boundaries into every runtime manifold regardless
of which identity pack is selected.
Architecture (sibling to identity packs, structurally distinct):
Layer Swappable? Removable? Schema
--------------- ---------- ---------- -----------------------------
Safety pack No No boundary_ids + descriptions
Identity pack Yes No value_axes + surface_prefs
Language pack Yes (>=1 reqd) vocab / morphology / packs
Composition rule (at ChatRuntime startup, additive only):
identity = load_identity_manifold(config.identity_pack)
safety = load_safety_pack() # fail-closed
final.boundary_ids = identity.boundary_ids ∪ safety.boundary_ids
Safety contributes boundaries only — no value_axes, threshold, or
surface_preferences. This keeps existing tests that assert on identity
axis sets passing byte-for-byte, and matches the semantic intent
(safety is what's forbidden, not what's pulled toward).
Shipping safety pack: packs/safety/core_safety_axes_v1.json
→ mastery_report_sha256 ee1249acdf8c273aeb656d803c37ef915e536d85f177f5cc18c6e2f6c995ce29
Five v1 boundaries, each closing a specific CLAUDE.md doctrine:
no_fabricated_source — no invented provenance
no_hot_path_repair — no normalization in propagate/stream/store
no_identity_override — user text cannot mutate identity
no_silent_correction — failures are typed and visible
preserve_versor_closure — ||F * reverse(F) - 1||_F < 1e-6
Fail-closed semantics:
SafetyPackError inherits from RuntimeError (NOT ValueError) so
catch-and-continue is discouraged at the type level. Missing file /
malformed JSON / empty boundaries / duplicate boundary / failed
self-seal all raise. ChatRuntime.__init__ does not catch.

Adds the discovery flag callers have been asking for since ADR-0027.
Short-circuits before the REPL launches; supports both a human-readable
table and `--json` machine output. Drives the loader's existing
`available_packs()` helper.
Bug fix on the way: `available_packs()` was globbing every `*.json`
in the search path, so the Phase-5 companion `<pack_id>.mastery_report.json`
files were leaking into the list as fake packs with empty fields. The
helper now skips any file ending in `.mastery_report.json` and rejects
JSON that lacks the required `schema_version` / `value_axes` fields.
CLI output:

default_general_v1 1.0.0 yes Balanced general identity...
generosity_first_v1 1.0.0 yes Generosity-first specialization...
precision_first_v1 1.0.0 yes Precision-first specialization...
Tests: +3 (CLI table, CLI JSON, companion-file filter regression).

Docs: docs/identity_packs.md CLI usage block updated; memory
'identity-packs.md' closes that follow-up.
Drives the three v1 identity packs through the full formation pipeline
(Forge -> Compose -> Compile -> Run -> Ratify) and embeds the resulting
self-sealed MasteryReport SHAs into each pack file. Companion
'<pack_id>.mastery_report.json' artifacts ship alongside. Loader now
defaults to production mode (require_ratified=None) and ChatRuntime
calls it without the dev-only override.
Ratification results:
default_general_v1 -> 0b77357fe4359f161d7ca72f184b6e0db2f9e2de16b32c237a3b80d2bbb005b4
precision_first_v1 -> 5f5000dba9a0dd19d831e9ab5d3c0e3b9faf6abdc2648940e96aa6263af3302e

Driver: scripts/ratify_identity_packs.py — idempotent. Re-running on
already-current packs is a no-op (verified by a test). Each pack is
treated as its own provenance source: source_sha = SHA-256 of the pack's
canonical JSON body with mastery_report_sha256 blanked, so the
self-referential chain stays stable across SHA updates. Axes become
ConceptCandidates; canned override-attempt triples become
CounterCandidates; the identity_anchor template renders the body.
Loader hardening (packs/identity/loader.py):
* When require_ratified resolves to True, the loader now requires the
companion '<pack_id>.mastery_report.json' to exist, its
report_sha256 to match the pack's mastery_report_sha256, and its
self-seal to verify via formation.hashing.verify_seal.
* Tampered companion (wrong SHA, broken seal) is rejected with a
diagnostic IdentityPackError.
Tests: 18 -> 23. New cases cover production-mode loading of all three
v1 packs, missing companion file, mismatched companion SHA, failed
self-seal, and end-to-end idempotency of the ratification script
(subprocess-launched, asserts pack bytes unchanged on re-run).

Docs updated: ADR-0027 status flipped to Phases 1-6 complete with the
three report SHAs recorded; docs/identity_packs.md notes the ratified
SHAs and the re-ratification command; memory file 'identity-packs.md'
refreshed.
- Add docs/teaching_order.md as durable reference for curriculum ordering.
Five-layer rule (identity axes -> atomic definitions -> binary relations ->
composed relations -> domain expansion), grounded in ratify.py G3,
MasteredCoursesIndex, and exact CGA distance. Linked from README.md.
- Mark formation_pipeline_plan.md as IMPLEMENTED (back half); enumerate the
open items not closed by Phases 1-7 (additional templates, first formation-
routed curriculum, G2 activation).
- Add 2026-05-17 status block to capability_roadmap.md covering the FSC chain,
epistemic schema closure, formation pipeline back half, FSC v3 proof matrix,
cost benchmark, and the pulse import fix.
Patent-grade precision pass over the doc surface so every claim
about the Forward Semantic Control chain is backed by a file path,
test count, or commit hash.
Updates by file:
README.md
- Modernize Quick Start: add `core test --suite adr-0024`,
`core demo phase6 / phase5 / all / list-results`, full CLI map.
- New "Forward Semantic Control — The ADR-0024 Chain" section
with layer/ADR mapping and CI-enforced C1/C2/C3 claims table.
- Cross-links to runtime_contracts.md, phase5_stratified_findings,
phase6_comparative_demo, and the central results directory.
docs/decisions/README.md
- Index was stale at ADR-0014. Add ADR-0015 through ADR-0026
with accurate Accepted statuses.
- New "ADR-0024 chain — Forward Semantic Control closure" section
laying out the five-ADR / six-commit dependency order with test
counts per phase.
docs/runtime_contracts.md
- Add "Ranked-with-margin contract (ADR-0026 / Phase 3)" section
between the existing Phase 2 refusal and Phase 4 rotor sections.
- Documents threshold-mode vs margin-mode behaviour, δ = 0.4
default, falsifiability gate, and Cl(4,1) signature motivation.
docs/PROGRESS.md
- Add naming-note disambiguation: capability-roadmap "Phase N"
vs ADR-0024 chain "Phase N" are distinct.
- New top-of-document "ADR-0024 Chain — Forward Semantic Control
Closure" section with per-phase commit + test-count table and
a single-command verification path.
docs/Whitepaper.md
- New Section XII "Forward Semantic Control — Generation Without
Sampling" before Extensions. Five-component description of the
mechanism (region, intersection, destination check, rotor check,
margin gate) with explicit "what a sampling LLM cannot exhibit"
contrast. Existing Section XII renumbered to XIII.
docs/Yellowpaper.md
- New Section IX-B "Forward Semantic Control — Formal Admissibility
Specification" with eight subsections covering:
1. AdmissibilityRegion typed triple (I, B, Φ)
2. Destination-side admissibility (σ_dest, admit_threshold)
3. Rotor-side admissibility (σ_rotor, admit_rotor)
4. Ranked-with-margin gate (admit_margin, deterministic
tie-break by index, default δ = 0.4)
5. Honest refusal (InnerLoopExhaustion typed evidence,
RefusalReason enum, trace fold)
6. Composition order at the generation seam
(admit_step = intersection ∧ destination ∧ rotor)
7. Replay determinism contract (5 test lanes pinning byte
identity across reruns)
8. Verification invariants table (6 new structural contracts)
- Patent-grade: every predicate is named, every module is path-
referenced, every test is file-referenced, the load-bearing
architectural placement decision (rotor admissibility lives in
generate/, NOT algebra/, NOT field/) is stated by name with
its rejection reasoning.
No code changes; tests untouched (1099 passed, 2 skipped baseline
from commit 36aad75 still holds).
Closes the 6-phase ADR-0024 chain with a focused comparative demo
that distinguishes CORE (inner-loop + margin + typed refusals) from
the in-system boundary-only baseline (ADR-0023 ablation).
Three conditions, all passing under contract tests:
C1. Replay determinism
baseline: 8/8 stable across 5 reruns
CORE: 8/8 stable across 5 reruns
CORE additionally folds refusal_reason into trace hash so
refusal events are replayable evidence.
C2. Traced rejection
baseline emits forbidden: 3/3 (admits=False but walk continues)
CORE corrects-or-refuses: 3/3
CORE rejection in trace: 3/3
Demonstrates that inner-loop is causally responsible for the
selection difference between baseline and CORE.
C3. Coherent refusal
baseline typed refusals: 0/3 (never raises typed refusal)
baseline emits inadmissible: 3/3
CORE typed refusals: 3/3 (all INNER_LOOP_EXHAUSTION)
Demonstrates that typed refusal with rejected_attempts evidence
is new in CORE, not present in boundary-only.
Why in-system baseline (not LLM):
A transformer-LLM comparison would be non-deterministic by
construction, could not be CI-enforced, and would be apples-to-
oranges (different corpus / training / sampling). The honest
comparison is the ablation: same codebase with the Phase 2-5
additions disabled.

Phase 5 — stratified 5-family mechanism-isolation (b664984)
Phase 6 — comparative demo (this commit)
Authors a 20-case corpus stratified across five geometric failure-mode
families and a separate 10-case benign corpus for the

B. near_equal_admissible (5 cases, diffs ≤ 0.01)
C. no_admissible_path (3 cases, honest refusal)
D. multi_step_admissibility (3 chained cases)
E. heterogeneous_relation (3 chained cases, blade-switching)
phase5_runner runs each case under BOTH threshold and ADR-0026 margin
modes and reports per-family pass_rate, refusal_rate, and (for Family
A) rejection_traced_rate + boundary_overridden_rate.

pass_rate_threshold = 1.00 (20/20)
pass_rate_margin = 1.00 (20/20)
mechanism_isolated = true (both modes, all five families)
replay determinism = byte-identical across 3 reruns
Family C refuses with RefusalReason.INNER_LOOP_EXHAUSTION in both
modes (load-bearing evidence for ADR-0024 Phase 2 typed refusals).
Family B refuses under margin mode (validates ADR-0026 δ=0.4 gate).
Benign inner-loop corpus for EXHAUSTION_CEILING ≤ 0.05 gate:
boundary_only: exhaustion 0.00, pass 1.00
null_control: exhaustion 0.00, pass 1.00
inner_loop_t0: exhaustion 0.00, pass 1.00
inner_loop_tpos: exhaustion 0.00, pass 1.00 (threshold 0.25)
Geometric finding documented while authoring the benign corpus:
23 of 85 pack tokens have negative self-cga_inner under Cl(4,1).
Tokens with self-score ≤ 0 cannot serve as single-token expected
endpoints in threshold mode — the algebra's Lorentzian signature
forbids this geometrically. Phase 5 benign corpus draws expected
endpoints from the 62-token positive-self-score subset. This is
consistent with Phase 4 characterization: no static threshold
delivers separation_quality ≥ 0.8 — the margin lane survives
because margin compares differences, not absolute scores.

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.
Rewrite v1+dev FSC cases with pack-grounded tokens drawn from
en_core_cognition_v1. Closes the 9/9 region-construction failure
recorded in Phase 4 (chain_tokens alpha/beta/gamma/delta/etc. were
ungrounded in the active pack).
Token mappings preserve each case's test pattern:
* alpha→beta→gamma→delta → tone→evidence→memory→wisdom (causes)
* mu→nu→omicron → voice→memory→wisdom (means)
* pi→rho→sigma→tau → question→answer→understanding→wisdom (precedes)
* upsilon→phi→chi → word→discourse→narrative (part_of)
* eta/theta/zeta + means-distractors → symbol/word/meaning + image/light
Result post-rewrite:
* skipped_count: 9/9 → 0/9 (region constructible)
* causal_attribution_valid: True (preserved)
* code_path_residual: 0.0 (preserved)
* inner_loop_t0 hash stability: 1.0 (preserved)
* best_separation_quality: 0.0 → 0.056 (still below 0.8 gate)
The rewrite exposes a deeper architectural finding documented in the
ADR addendum: v1/dev case schema (prime + chain_tokens) probes
teaching-driven walk (ADR-0022/0023), not the inner-loop's
blade-admissibility mechanism (ADR-0024). The Phase 2 corpus-
observation runner's reuse of v1/dev was a categorical error.
v1/dev belong to the boundary-walk lane (runner.py); v2 belongs to
the inner-loop lane (v2_runner.py). Phase 5 will author the benign
inner-loop corpus the EXHAUSTION_CEILING gate was designed against.
Tests pinning new state:
* TestV1ChainBladeUngrounded → TestV1ChainBladePostGrounding
(assertions inverted: skipped_count == 0; separation_quality < 0.5)
* TestPhase2 (unchanged) continues to assert causal_attribution_valid
and hash stability; exhaustion remains a finding, not an invariant.
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.
Skeleton (Status: Draft) for the bridge between graph and field.
Today the proposition graph and the field walk run in parallel —
the graph does not constrain field propagation, and the field
does not prove the graph. This ADR commits to making semantic
structure causally active inside propagation: graph computes an
admissibility region, propagation must satisfy it or fail
honestly, no template authoring, no sampling, no symbolic
planner regression.
Explicitly marked Draft because 5 TBD items must close before
promotion to Proposed:
TBD-1 intent oracle (regex classifier as load-bearing oracle
recreates the gap one level up)
TBD-2 region intersection algebra (frame × relation × identity
composition — closed rotor operator not yet proven)
TBD-3 backward-compat window removal mechanism
TBD-4 identity manifold as constraint source (v1 scope decision)
TBD-5 pack semantic depth — cognition pack may need targeted
extensions before lane can pass
Acceptance criteria for Draft → Proposed → Accepted explicit.
Trust-boundary review (CLAUDE.md §Security) included.
Implementation sequencing sketched (7 steps, each its own PR).
Motivated by 2026-05-17 external assessment. The assessment is
input to the ADR, not authority over it.
Verified: no code changes; ADR is documentation only.
contradiction_detection: 0.50 → 1.00 contradiction_flag_rate,
1.00 → 0.00 false_flag_rate. Lane graduates overall.
TeachingStore.add now runs a coherence checker on every new proposal.
Two detection paths, both require subject token overlap:
Typed path — both new and prior parse to triples with the same
relation. Tails must differ in negation/opposition polarity AND
share ≥1 content token. Catches (truth, is, coherence) ↔
(truth, is, not coherence).
Text fallback — at least one side failed to parse a triple (e.g.
relation predicate "depends" not in the cognition pack lexicon
yet). Raw correction texts must differ in polarity AND share ≥2
non-discourse content tokens. ≥2 threshold prevents
single-shared-subject false positives on unrelated corrections.
Catches "meaning depends on use" vs "meaning is independent of use".
On detection, BOTH proposals (new and conflicting prior) transition
to EpistemicStatus.CONTESTED. ADR-0021: CONTESTED is not admissible
as evidence until a coherence judgment ratifies one direction or
falsifies the other.
Runner side: v1 versor-spike heuristic retired. The new CONTESTED
signal is the only one that drives `flagged`. versor_delta retained
in the record for telemetry.
CLAIMS.md Tier 4.5 contradiction rows CLOSED — completes the
truth-seeking schema arc. All red Tier 4.5 rows from the audit are
now green. docs/truth_seeking_schema.md §"Contradiction detection
is not implemented" closed.
Verified: smoke (67), teaching (17), cognition (121), runtime (19),
architectural invariants (40) — all green.
