First worked attempt at promoting a domain under the ADR-0120
expert promotion contract. The contract refuses honestly.
Gate evaluation against live state:
ADR-0114a obligations: 10 of 10 pass
ADR-0120 contract-level gates:
audit_passed_holds ✓
correct_rate (public) ✓ 150/150 = 1.0
correct_rate (sealed) ✗ 0/1319 = 0.0 < 0.60 floor
signed_expert_claim ✗ (no entry, downstream of correct_rate)
Decision: mathematics_logic NOT promoted; stays at audit-passed.
Substantive blocker: parser grammar covers 0/1319 of real GSM8K.
What this proves
- The contract is genuinely falsifiable. ADR-0120 §"Threshold
rationale" deliberately set the floor above current measurement
so the first attempt would defer honestly. Same load-bearing
pattern as ADR-0107 → ADR-0110 for audit-passed.
- Wrong-zero discipline holds against real GSM8K (the load-
bearing positive claim). CORE refuses every problem outside
its grammar without confabulating on a single one.
What unlocks the promotion
Multi-ADR parser-expansion arc lifting sealed-GSM8K correct_rate
from 0.0 to ≥ 0.60. Each construction class (rate/comparison/
percentage/time-modal/etc.) ships as its own scoped ADR with:
- parser+solver+verifier+realizer extensions
- re-measurement on sealed holdout
- ADR-0118a OOD re-measurement (no surface-feature regression)
- ADR-0125 perturbation re-measurement (no invariance regression)
- ADR-0119.5 adversarial re-measurement (no new misparses)
Honest-fitting discipline: every lift is graded on the anti-
overfit obligations BEFORE the correct_rate change counts.
Tests: 6/6 with CORE_HOLDOUT_KEY; 4/6 + 2 skipped without (matches
ADR-0119.7 seal discipline).
This deferral demonstrates the expert tier's promotion machinery
is load-bearing — the gate has refused at least once before any
domain reaches it.

Defines the `expert` ledger tier (sixth status above `audit-passed`)
and the composition gate that governs every future promotion.
The gate composes ALL TEN ADR-0114a obligations plus three contract-
level checks:
- audit_passed predicate must hold
- correct_rate >= 0.60 on public AND sealed holdout splits
- signed expert_claims entry whose digest reproduces byte-equal
Numeric thresholds (load-bearing choices documented with rationale):
- correct_rate floor: 0.60 ("advanced" — above weak open-source LLMs,
forces real architecture work, raisable later)
- depth-curve flatness ε: 0.05 (accuracy(N) ≥ accuracy(d1) · 0.95^(N-1))
- drift tolerance from promotion: ±0.02
Documents the post-ADR-0120 sequence in Open Candidate Directions:
Phase 1: ADR-0121 first worked math promotion (likely deferral)
Phase 2: parser-expansion arc to lift sealed-GSM8K correct_rate
Phase 3: math expert promotion succeeds
Phase 4: second domain = symbolic_logic (60-70% of math substrate cost;
ProofWriter / PrOntoQA benchmark; same machinery class)
Phase 5: third domain = high-stakes refusal-centric (medical or legal;
wedge-sharpener; needs two prior successes first)
Phase 7: open candidate — multi-reviewer threshold signing for expert
No code lands with this ADR. Implementation ships under ADR-0120a
to keep the contract change reviewable independently.
The first promotion attempt (ADR-0121) will likely defer on the
correct_rate gate — current measurement is 0/1319 on real GSM8K.
That deferral IS the contract working as designed; same load-
bearing pattern ADR-0107 → ADR-0110 demonstrated for audit-passed.

The 1,319 GSM8K test cases are now sealed at
evals/gsm8k_math/holdouts/v1/cases.jsonl.age, age-encrypted to the
ADR-0119.1 recipient. Plaintext never touched disk in the working
tree; only ciphertext is committed.
First honest CORE-vs-real-GSM8K measurement
cases_total: 1319
correct: 0
wrong: 0 ← ADR-0114a Obligation #4 holds against external corpus
refused: 1319
overall_pass: True
Zero confabulation. Parser refuses what it can't grammar-handle; the
"wrong == 0" discipline survives the move from CORE-original cases
to a real public benchmark. The 0/1319 correct rate is the truthful
gap that ADR-0120's threshold work will quantify.
What landed
scripts/seal_gsm8k_test.py
- Loads GSM8K via datasets.load_dataset("openai/gsm8k", "main")
- Strips worked-solution prose; extracts final-answer integer/float
after "####" (handles "2,125" → 2125 thousands-separator)
- Reads recipient from docs/holdout_recipients.txt (single repo key
per ADR-0119.1)
- Encrypts via pyrage; writes only ciphertext
- Refuses to overwrite test path with train-derived seal
evals/gsm8k_math/runner.py
- Empty expected_unit (sentinel) skips unit-comparison; grades on
answer value alone. Required because GSM8K answers carry no unit
structurally. wrong-zero discipline preserved.
tests/test_adr_0119_7_sealed_gsm8k.py — 6 invariants:
1. sealed file present + age-formatted
2. no plaintext companion files (sibling-leak guard)
3. decrypted JSONL matches documented schema
4. runner against decrypted suite produces wrong==0
5. tests skip (not fail) when CORE_HOLDOUT_KEY unset
6. case ids match "gsm8k-test-NNNN" pattern
Defensive gitignore: plaintext patterns under
evals/gsm8k_math/holdouts/v1/ are explicitly excluded.
ADR-0114a obligation roll-up
10/10 discharged for the gsm8k_math lane:
#1 ✓ sealed-holdout (fab_control + GSM8K test)
#2..#10 ✓ as before
Phase 5 status: 5.1..5.7 done; 5.8 in flight (PR #149). After 5.8
merges, ADR-0120 (first expert promotion contract) becomes
feasible.
Test plan
- pytest tests/test_adr_0119_7_sealed_gsm8k.py with CORE_HOLDOUT_KEY → 6/6
- pytest without CORE_HOLDOUT_KEY → 3 pass + 3 skip
- core test --suite smoke -q → 67/67
- CLAIMS.md regenerated (no diff)
- HF token NEVER in repo (saved at ~/.cache/huggingface/token, mode 600)

Umbrella ADR for Phase 5 of ADR-0114. Decomposes the eval-lane work
into eight sub-phases (5.1..5.8) that ship under their own ADRs.
Sub-phase scope:
5.1 — sealed-holdout encryption (one lane, fabrication_control)
5.2 — CORE-original GSM8K-style corpus (dev + public, 200 cases)
5.3 — lane runner (parser → solver → verifier → realizer)
5.4 — frontier-baseline comparison (Obligation #7)
5.5 — adversarial generation; misparse rate zero (Obligation #8)
5.6 — depth-curve measurement harness (Obligation #6, measurement)
5.7 — sealed GSM8K test as the holdout (Obligation #1, lane-side)
5.8 — overall lane gate; new gsm8k_capability_shape
Roadmap only — no code lands with this ADR. Each sub-phase ships
independently and discharges a specific ADR-0114a obligation.
Critical invariant: dev + public splits are CORE-original; the real
GSM8K test set enters only via the encrypted holdout under 5.7.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Phase 4 of the ADR-0114 GSM8K-math roadmap. Consumes a SolutionTrace
and emits one sentence per step plus setup + answer sentences. Pure
function; same trace → byte-equal RealizedTrace.
What landed
generate/math_realizer.py
- realize(initial_state, trace) -> RealizedTrace
- Frozen RealizedTrace dataclass with canonical_bytes() + as_prose()
- Per-kind sentence rules (add / subtract / transfer / multiply×2 /
multiply×3 / multiply-general / divide)
- Singular/plural surface rule matches parser canonicalization
- Typed RealizerError on unrecognized step kinds
tests/test_math_realizer.py — 60 cases pinning five invariants:
1. All 50 dev-set cases realize without error
2. Determinism: byte-equal RealizedTrace across two calls
3. Setup sentence count == initial_state count
4. Step sentence count == operation count
5. Answer sentence contains the resolved value + unit
ADR-0114a obligation discharge update
ADR-0118 hardens determinism (#9) across a third layer (realizer)
and makes #3 / #10 human-inspectable via the prose surface. No
obligation is directly newly discharged by ADR-0118; it's substrate
for ADR-0119 GSM8K eval lane.
Round-trippability of the prose through the parser is explicitly
out of scope for this phase. The trace is the verifiable artifact
(ADR-0117); the prose is human-readable documentation.
Tests: 60 new realizer cases; 546 total green across realizer +
parser + solver + verifier + OOD; 67/67 smoke green.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Phase 3 of the ADR-0114 expert-capability roadmap. Re-applies every
step of a SolutionTrace from the input graph's initial state and
asserts byte-equal reproduction of answer_value. Pure function; same
(graph, trace) → byte-equal VerifierVerdict.
Why this is distinct from the solver
ADR-0116's solver enforces correctness at construction. ADR-0117's
verifier is a SECOND, INDEPENDENT implementation that re-derives
every value the trace claims. The verifier does NOT call solve(). It
re-implements the operation semantics from ADR-0116 directly inside
_verify_step. If the solver had a bug or was tampered with after the
fact, the verifier catches it.
Six checks per verdict (named, ordered, audit-logged):
1. graph_canonical_hash_matches
2. pack_id_matches
3. pack_lemmas_resolve
4. step_pack_lemma_ids_match_bindings
5. step_replay_matches_before_after
6. answer_value_reproduces
Seven named tamper classes all caught:
- mutated before_value / after_value / operand of any step
- mutated pack_lemma_id of any step
- mutated graph_canonical_hash
- mutated answer_value
- mutated pack_id
- mutated target_before / target_after of transfer step
ADR-0114a obligation update
#3 Replay-equal trace — now discharged at VERIFIER FIDELITY
(was solver-only under ADR-0116). A third party with only
(graph, trace, pack) can reproduce the answer byte-equal.
Five of ten obligations now load-bearing: #3, #4, #9, #10 plus
in-flight #2 (Codex's ADR-0118a OOD generator).
Tests: 62/62 verifier suite green; 67/67 smoke green; existing
solver + parser + schema suites unaffected.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Phase 2 of the ADR-0114 expert-capability roadmap. Consumes the
MathProblemGraph from Phase 1 and emits a SolutionTrace — ordered
operation applications ending at a numeric answer, byte-deterministic
across runs, with each step's operation bound to a pack-resolved
lemma identifier.
What landed
generate/math_solver.py
- solve(graph) -> SolutionTrace; pure function, no I/O, no globals
- SolutionStep dataclass with before/after values per step (for
verifier replay; ADR-0117 hardens)
- SolutionTrace with canonical_bytes() byte-deterministic JSON
- SolveError typed refusal: missing pack, division by zero,
unknown-references-nothing
language_packs/data/en_arithmetic_v1/
- 5 operator lemmas: add / subtract / multiply / divide / transfer
- role=operational_base (vocabulary-only; no domain claim)
- SHA-256-anchored lexicon + glosses; manifest carries
provenance=adr-0116:operator_seed:2026-05-22
tests/test_math_solver.py — 109 cases pinning five invariants:
1. Phase 2 exit criterion: ≥ 0.80 on parser-correct dev set
(current: 50/50 = 1.00)
2. Determinism: two solves produce byte-equal trace
3. Trace replay reproduces answer_value (verifier rehearsal)
4. Typed refusal on under-determined inputs
5. Every step.pack_lemma_id resolves to a real lexicon entry
in en_arithmetic_v1
ADR-0114a obligation discharge
Four of ten anti-overfitting obligations now have load-bearing
implementations in code:
#3 replay-equal trace — discharged (solver-layer)
#4 typed refusal — discharged (solver-layer)
#9 determinism — discharged (solver-layer)
#10 operation provenance via pack — DISCHARGED IN FULL
Removing the en_arithmetic_v1 pack now breaks every solve loudly.
The "operations bind to concepts, not hardcoded strings" claim is
architecturally true, not rhetorical.
Tests: 109/109 green on solver suite; 67/67 smoke suite green;
parser + schema suites still green from prior phases.

Documentation-only amendment to ADR-0114. Locks in the 10-point
falsifiable proof framework that any future `expert` ledger-tier
promotion (ADR-0120+) MUST require.
The obligations:
1. Sealed-holdout discipline
2. OOD surface variation ≥ 0.95 of public
3. Every correct answer ships with replay-equal trace
4. Refusal is first-class; misparse rate zero; zero `wrong` answers
5. Reasoning-isolation perturbation suite (invariance + predictable change)
6. Compositional-depth curve flat within documented ε
7. Frontier-baseline comparison on identical items, published
8. Adversarial generation; misparse rate zero
9. Determinism across release boundaries
10. Operation provenance via the pack (not hardcoded strings)
Each obligation is load-bearing and falsifiable: a domain that
cannot satisfy any one stays at `audit-passed`. ADR-0114a binds
ADR-0116..ADR-0120 to carry the obligations into implementation;
ADR-0120 finally invokes all ten as hard gates.
The audit-passed tier (ADR-0106/0109/0113) is unaffected. The two
tiers measure orthogonal properties: audit-passed verifies CORE
claim-shape compliance (transformer-unreachable invariants); expert
verifies capability with anti-overfitting proof.
No code change. Pure forward contract for the next phase of work.

First Phase of ADR-0114's expert-capability roadmap. Decomposed into four
sub-phases so each lands as its own auditable step:
1.1 schema + 5 seed cases + invariants ← this commit
1.2 45 more dev-set cases ← delegated (Codex)
1.3 the parser itself ← exit: ≥0.90 on dev set
1.4 runtime binding ← if non-trivial
What landed
- generate/math_problem_graph.py — typed dataclasses (Quantity,
InitialPossession, Operation, Unknown, MathProblemGraph) + frozen
validation + canonical_bytes() byte-deterministic serialization +
graph_from_dict roundtrip.
- evals/gsm8k_parser_dev/cases.jsonl — 5 seed cases (gpd-001..005)
covering single-add, single-subtract, multi-step, two-entity
transfer, and multi-entity sum constructions. Every case carries a
ground_truth_graph and the documented patterns it exercises.
- evals/gsm8k_parser_dev/README.md — authoring contract: schema,
pattern registry, canonicalization rules, Phase 1.1 scope boundary,
hand-solving rubric, distribution target for the remaining 45
cases. This is the spec Phase 1.2 authors work against.
- tests/test_math_problem_graph.py — 26 cases pinning four invariants:
round-trip byte equality, canonical_bytes() determinism, schema
rejection of malformed graphs, and ground_truth_graph ↔
expected_answer agreement (a hand-solver inside the test module
falsifies mis-authored cases).
Why this is sticky
The Phase 1.1 schema is load-bearing for Phase 1.2 (the 45 authored
cases will be written against it) AND Phase 1.3 (the parser will be
graded byte-equal against ground-truth graphs in this schema). Changing
the schema after Phase 1.2 lands requires an amendment ADR + rewriting
authored cases. The schema choices here are intentionally conservative.
Tests: 26/26 new; 67/67 smoke green.

The word "expert" in the previous status name implied raw-capability parity
with frontier LLMs on the same benchmark — which the gate does NOT verify.
What the gate actually verifies is CORE *claim-shape compliance*:
* signed digest (replay-reproducible from on-disk lane results)
* replay determinism (same inputs → byte-equal trace_hash)
* typed refusal (fabrication refused, not paraphrased)
* exact recall (no ANN, no cosine, no attention bottleneck)
* grounding-source provenance
These are claim shapes a transformer LLM cannot structurally produce
regardless of raw accuracy. A frontier LLM might score higher on the
same benchmark but cannot pass this contract.
Rename scope (semantics only, per ADR-0113):
status string "expert-demo" → "audit-passed"
predicate key predicates.expert_demo → predicates.audit_passed
reason key expert_demo_reason → audit_passed_reason
YAML key expert_demo_claims → audit_passed_claims
CLI command core demo expert → core demo audit-passed
output dir evals/expert_demos/ → evals/audit_passed/
artifact filenames expert_demo.{json,html} → audit_passed.{json,html}
HTML title CORE Expert-Demo: X → CORE Audit-Passed: X
Internal Python identifiers (module/file/function/class names like
`expert_demo.py`, `evaluate_expert_demo`, `ExpertDemoClaim`,
`expert_demo_claim_for`) are deliberately kept to minimize churn. ADR
file titles (ADR-0106..0112) preserved as historical record.
`expert` namespace reserved for ADR-0114+: an actual capability tier
above `audit-passed` backed by a public benchmark with a stated
threshold. ADR-0114 proposes the first such target — GSM8K-math —
laying out a falsifiable 7-phase arc (parser → solver → verifier →
stepped-realizer → eval lane → first `expert` ledger tier promotion).
Tests: 184 directly-affected tests green (140 capability/expert-demo
suite + 34 demo/audit-tour + 10 correction-cue). Smoke suite 67/67.

Closes the asymmetry between the `expert-demo` ledger status (audit
artifact only) and the actual `core demo` surface (runnable
walkthroughs producing HTML + JSON). Until this commit the word
"demo" in `expert-demo` was aspirational; now it corresponds to
something a reader can open.
What it does
- Reads the signed expert_demo_claims entry from docs/reviewers.yaml
- Loads latest on-disk result files for each attached lane × split
- Re-derives the evidence-bundle digest and asserts byte-for-byte
match against the signed claim_digest — this is the load-bearing
audit step, now exercised at two independent enforcement points
(ledger gate + showcase)
- Runs each lane's metrics through the ADR-0109 lane-shape registry
and surfaces the verdict
- Picks the first three cases from each split verbatim (deterministic
by file order) and renders them as HTML for inspection
- Emits expert_demo.json (canonical bytes, deterministic) + expert_demo.html
Surface
core demo expert --domain mathematics_logic
core demo expert --domain physics
# → evals/expert_demos/<domain>/latest/expert_demo.{json,html}
Read-only by construction: cannot mutate docs/reviewers.yaml or any
lane result file. Tested. Unpromoted domains raise ValueError —
no silent fallback, no "preview" mode that fakes a showcase.
Generated artifacts are gitignored — the inputs they derive from are
already committed, so duplicating the renders would just churn the
tree.
Tests: 16 new cases pinning all five ADR-0112 invariants. Smoke suite
still 67/67 green.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Second worked promotion exercising the ADR-0106 + ADR-0109 contract
on a domain distinct from mathematics_logic. No contract change.
Evidence:
- foundational_physics_ood: accuracy=1.0 (117/117 public, 39/39 holdout)
- inference_closure: all_pass_rate=1.0 (shared with math, distinct digest via domain_id)
- fabrication_control: refused=n, fabricated=0 across all classes (shared)
Signed claim digest: a104cad136f3219df05dc7ce6a78437c02f7b5827cd3cdce568db3acda6a43ed
Bridge landed: cases_plaintext.jsonl dev-mode fallback for
foundational_physics_ood (matches ADR-0105 convention; analogous to the
math/inference bridges in ADR-0110). One small file, not a contract change.
Tests:
- tests/test_adr_0111_physics_expert_demo.py — 4 invariants, 6 cases
- tests/test_adr_0110_math_expert_demo.py — relaxed "only math promoted"
to "math stays promoted" (load-bearing for ADR-0110 is persistence)
- tests/test_capability_reports.py — physics row now expert-demo
Retires the "first promotion was math-specific" objection: the bridges
ADR-0110 landed were correctly scoped, and the contract holds across
two distinct domains using shared lane infrastructure with distinct
digests.

- README.md: fix broken evals/CLAIMS.md link to root CLAIMS.md;
add 'Evidence-Governed Domain Layer' section pointing to the
ADR-0091/0096/0106/0109 contract chain and current ledger state
(math at expert-demo, four other domains at reasoning-capable).
- docs/decisions/README.md: extend the 'fully accepted' slate from
0091..0105 to 0091..0110 with ADR-0106 through 0110 entries; extend
the 'Evidence-governed domain chain' chain-notes section to reflect
the expert-demo arc (refused-amended-succeeded narrative).
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.
Two new intent shapes + composers turn the runtime's corpus
density into operator-visible articulation. Both consult the
cross-corpus aggregator from ADR-0064; no new ratification needed.
P3.3 — chat/narrative_surface.py + IntentTag.NARRATIVE.
Classifier patterns (registered BEFORE generic DEFINITION):
^tell\s+me\s+about\s+
^describe\s+
^what\s+(?:can|do)\s+you\s+(?:say|know)\s+about\s+
narrative_grounded_surface(subject, max_clauses=4) walks every
reviewed chain rooted on subject across all registered teaching
corpora. Dedupes by (connective, object) — cause + verification
carrying the same predicate emit one clause, not two. Sorts by
(intent, connective, object) for replay stability.
Surface format:
"{X} — narrative-grounded ({corpus_ids}): {dX1}; {dX2}.
{X} {conn1} {O1} ({dO1}); {X} {conn2} {O2} ({dO2}).
No session evidence yet."
Cross-corpus subjects (e.g. mother in relations_v2) emit
narrative-grounded (relations_chains_v2) tag; cognition subjects
emit cognition_chains_v1 tag. Multi-corpus subjects (when
applicable) emit composite "corpus_a + corpus_b" tag.
P3.4 — chat/example_surface.py + IntentTag.EXAMPLE.
Classifier patterns:
^(?:give|show)\s+(?:me\s+)?an?\s+(?:example|instance)\s+of\s+
^example\s+of\s+
example_grounded_surface(object_lemma, max_examples=3) walks chains
where the lemma is the OBJECT — inverts the typical subject-keyed
access pattern. Dedupes by subject; sorts by (intent, subject,
connective).
Surface format:
"{X} — example-grounded ({corpus_ids}): {dX1}.
Example: {subj1} {conn1} {X}; {subj2} {conn2} {X}.
No session evidence yet."
Cross-cutting:
- Both intents added to _OOV_INTENT_TAGS — fall through to OOV
invitation when subject is unknown (Phase 2 gradient discipline).
- Both tagged grounding_source="teaching" (same provenance tier
as the existing teaching_grounded_surface).
- No prose generation, no new mutation surface.
Live verification:
> Tell me about truth.
[teaching] truth — narrative-grounded (cognition_chains_v1):
cognition.truth; logos.core. truth grounds knowledge
(cognition.knowledge); truth requires evidence (cognition.evidence).
> Give me an example of knowledge.
[teaching] knowledge — example-grounded (cognition_chains_v1):
cognition.knowledge. Example: truth grounds knowledge;
understanding requires knowledge; evidence grounds knowledge.
> Tell me about mother.
[teaching] mother — narrative-grounded (relations_chains_v2):
kinship.parent.female. mother precedes daughter (kinship.child.female).
> Describe photosynthesis.
[oov] I haven't learned 'photosynthesis' yet (intent: narrative). ...

Mirrors the chain-gap pipeline (Phase 1.1+1.2) for vocabulary gaps:
the OOV invitation surface (P2.1) now emits structured signals that
operators can aggregate, rank, and auto-promote into reviewed
PackMutationProposal candidates — closing the OOV loop the same way
Phase 1 closed the chain loop.
Three new modules + two new CLI surfaces:
teaching/oov_sink.py.
OOVCandidate dataclass mirroring teaching.discovery.DiscoveryCandidate.
OOVBufferSink (in-memory) + OOVMonthlyFileSink (append-only JSONL
under <root>/<YYYY>/<YYYY-MM>.jsonl — same layout as discovery sink
so the aggregator reuses the file-walk machinery).
hash_oov_candidate_id(token, intent, trace_hash) — deterministic
32-char hex id matching DiscoveryCandidate's replay invariant.
format_oov_candidate_jsonl — sorted-keys compact JSONL line.
teaching/oov_gaps.py.
aggregate_oov_gaps(root, since, sample_limit) groups emitted
candidates by token, tracks intent-shape union (a token asked under
multiple intents is a stronger curriculum signal), splits
boundary_clean from boundary_tainted counts, supports --since
YYYY-MM filtering via the sink's file naming convention.
Pure reader; never mutates the sink. Deterministic ordering:
(count desc, token asc).
teaching/oov_promotion.py.
promote_oov_gaps(gaps, threshold, include_tainted, suggested_packs)
lifts threshold-crossing tokens to OOVPromotion records.
- boundary_clean_count gates promotion by default (tainted-only
tokens may indicate the prompt hit a safety axis rather than a
vocab gap).
- --include-tainted flag for operator override.
- threshold < 1 raises.
- queue_id deterministic: ``oov:<token>@<threshold>`` — diffable
across runs.
- suggested_packs lists mounted packs but does NOT recommend one
— domain inference is out of scope (would require a stochastic
classifier). Operator picks the destination.
Runtime wiring:
ChatRuntime.attach_oov_sink(sink) mirrors attach_discovery_sink.
Runtime emits one OOVCandidate JSONL line per turn whose
grounding_source == "oov", no-op when no sink is attached.
Intent classifier is now invoked when EITHER sink is attached
(was: only discovery sink) — both downstream paths need it.
CLI:
core teaching oov-gaps [--top N] [--since YYYY-MM] [--root PATH]
[--sample-limit N] [--json]
core teaching oov-queue [--threshold N] [--include-tainted]
[--root PATH] [--since YYYY-MM] [--json]
ADR-0065 documents the full design (five-tier honesty gradient,
P2.1-P2.4 architecture). README.md updated with the ADR-0065
index entry.

ADR-0064 is the corpus-layer sibling of ADR-0063. The teaching-grounded
surface composer was hardcoded to cognition_chains_v1, so kinship CAUSE/
VERIFICATION prompts fell through to the universal disclosure even though
en_core_relations_v1 was mounted on the live runtime (ADR-0063).
Architectural change in chat/teaching_grounding.py:
- New TeachingCorpusSpec dataclass (corpus_id, path, pack_id).
- TEACHING_CORPORA tuple registers every active corpus. Each
corpus is 1:1-bound to one lexicon pack — cross-domain triples
deferred per docs/teaching_order.md §5.
- _load_corpus(spec) loads one corpus with pack-residency scoped
to its declared pack.
- _all_chains_index() aggregates across all registered corpora
(first-match-wins; cognition first preserves byte-identity).
- _pack_for_corpus(corpus_id) → bound pack lexicon.
- clear_teaching_caches() atomic cache invalidation.
- TeachingChain gains corpus_id field → surface tag follows resolving corpus.
Wiring updates:
- teaching_grounded_surface + teaching_grounded_surface_composed
consult _all_chains_index; surface tag follows chain.corpus_id.
- teaching/discovery.py gate uses chat.pack_resolver.is_resolvable
(any mounted pack) + _all_chains_index (any registered corpus).
- teaching/replay.py _swap_corpus_path rewrites the registry path
+ clears all teaching caches during the gate's transient phase.
Active corpus bytes unchanged (replay invariant preserved).
- evals/learning_loop/run_demo.py scene-5 swap mirrors the new
pattern so the demo still grounds against transient corpora.
Back-compat preserved: _corpus_index, _CORPUS_PATH, TEACHING_CORPUS_ID
remain cognition-corpus-specific for audit/replay consumers.
Phase 1.4 — relations_chains_v1 seeded with 7 reviewed kinship chains:
cause_parent_precedes_child
cause_child_follows_parent
cause_ancestor_precedes_descendant
cause_descendant_follows_ancestor
cause_family_grounds_parent
verification_child_requires_parent
verification_descendant_requires_ancestor
5 of 8 relations lemmas covered. All connectives already humanised.
Strict pack-internal to en_core_relations_v1 (no cross-domain in v1).
Seed pattern matches cognition_chains_v1's original pre-ADR-0055 seed.
Live verification:
> Why does parent exist?
parent — teaching-grounded (relations_chains_v1):
kinship.ascendant.direct; kinship.parent.
parent precedes child (kinship.descendant.direct).
grounding_source = teaching
Cognition eval byte-identical to pre-ADR baseline:
public: intent 100% / surface 100% / term 91.7% / closure 100%
holdout: intent 100% / surface 100% / term 83.3% / closure 100%
Lanes green: smoke 67 / cognition 121 / teaching 17 / packs 6 /
runtime 19 / algebra 132 / full 1933 passed.
ADR-0063 closes the ADR-0048/0050/0053/0061 hardcoded-cognition-pack
asymmetry. New chat/pack_resolver.py provides resolve_lemma(lemma,
pack_ids) → (resolving_pack_id, semantic_domains) across an ordered
tuple of mounted lexicon packs (first-match-wins, lru_cache per-pack).
Surface composers in chat/pack_grounding.py now consult the resolver
instead of a hardcoded en_core_cognition_v1. en_core_relations_v1
joins RuntimeConfig.input_packs defaults; kinship lemmas now ground
on the live path:
> What is a parent?
parent — pack-grounded (en_core_relations_v1):
kinship.ascendant.direct; kinship.parent; biology.progenitor.
No session evidence yet.
Cross-pack comparison (knowledge × parent) renders composite tag
(en_core_cognition_v1 × en_core_relations_v1). Cognition lane
remains byte-identical: cognition is resolved first and the surface
format for cognition lemmas is unchanged.
Cognition eval (byte-identical to pre-ADR baseline):
public → intent 100% / surface 100% / term 91.7% / closure 100%
holdout → intent 100% / surface 100% / term 83.3% / closure 100%
Curated lanes green: smoke 67 / cognition 121 / teaching 17 /
packs 6 / runtime 19 / algebra 132.
New tests: test_pack_resolver.py (28) + test_cross_pack_grounding.py
(17). test_en_core_relations_v1_pack.py: default-input-packs guard
inverted. test_pack_grounding.py: two stale ADR-0048 tests rewritten
(premises invalidated by ADR-0052/0061; now use fully-out-of-pack
prompts).
chat/teaching_grounding.py UNCHANGED — cognition_chains_v1 corpus
stays cognition-only. Cross-pack teaching corpora are the natural
ADR-0064.
