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.

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.

Suite status (all green):
cognition 121, teaching 17, runtime 19, formation 182, smoke 67
identity / safety / surface divergence suites: 108 tests passing
(was 88 before this ADR; +20 safety-check tests)
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.
Suite status (all green):
cognition 121, teaching 17, runtime 19, formation 182, smoke 67
identity+safety+English+depth divergence 71
score decomposition 17
Scope limits (documented in ADR-0031):
- English-only at v1 (depth languages use canonical ADR-0030 phrases)
- Lex tie-break is operational not semantic — pack authors can re-key
if they need a different priority
- No dominance-driven phrasing (Interpretation A); preserved as
forward-compatible follow-up
Docs: ADR-0031 (Accepted) recorded; docs/identity_packs.md gains
§Axis-specific hedge phrases section and updated v1-pack SHAs; memory
'identity-packs.md' refreshed.
Closes the 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).
test_identity_packs.py: 23 -> 26. cognition / smoke green.
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
generosity_first_v1 -> 91716117558113f74b2c6d07a804cb324f262d62b743523d901d1386a4f85ae4
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).
Suite status: cognition 121, teaching 17, runtime 19, formation 182,
smoke 67 — all green.
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.
