feat(adr-0044, adr-0045): domain ethics pack + long-context comparison

Browse source 
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.

Reference: ADR-0027 through ADR-0042 (the pack-layer architecture).
Two pack-driven runners produce per-pack measurements across the three

Invokes the production SentenceAssembler with each pack's SurfaceContext
over 10 cases × 5 alignment bands. Reports per-pack rates of bare /

same code path used by the runtime.
Runner 2 — Pack-aware refusal calibration

This report combines a controlled CORE measurement with frozen citations of
published transformer long-context recall figures. The two measurements use
different inputs (synthetic float32 versors vs natural-language needles) and
are not directly comparable on benchmark-for-benchmark grounds; the
comparison is at the architectural level — exact-scan recall vs

Procedure: for each N ∈ {100, 1_000, 10_000, 100_000}, populate a fresh
VaultStore with N-1 random float32 versors and one distinguished needle
at a known index; query the vault with the needle vector; verify the
top-1 result is the planted index. Determinism: fixed seed schedule.
Component 2 — Published transformer baselines (frozen citations)
Anthropic Claude 2.1, OpenAI GPT-4 Turbo 128k, Google Gemini 1.5 Pro,

# ADR-0044 — Medical / clinical ethics pack (worked-example domain pack)
Status: Accepted (2026-05-17)
## Context
ADR-0033 shipped the third pack-layer sibling (`packs/ethics/`) with
exactly one ratified pack: `default_general_ethics_v1`. Through
ADR-0034 → ADR-0042, the per-commitment remediation tiers (audit /
hedge / refuse) and the full audit + telemetry stack landed. The
shape of the system is complete; the worked example is missing.
Robotics, healthcare, legal, and financial deployments are the
audience the pack-layer architecture exists to serve. Until at least
one domain pack ratifies end-to-end through the formation pipeline,
the deployment story is "you could do this" rather than "here is what
that looks like."
## Decision
Ship `packs/ethics/medical_clinical_ethics_v1.json` as the worked
example. Six commitments, partitioned across the three remediation
tiers:
| Commitment | Tier |
|---|---|
| `no_dosing_recommendation` | refuse |
| `no_emergency_triage_authority` | refuse |
| `defer_diagnosis_to_clinician` | hedge |
| `surface_evidence_grade` | hedge |
| `disclose_no_clinician_relationship` | audit |
| `respect_patient_autonomy` | audit |
The pack is ratified through `scripts/ratify_ethics_pack.py` (which
now drives both packs). A companion `medical_clinical_ethics_v1.mastery_report.json`
self-seal lands next to it. Production-mode loading verifies the
seal; dev override remains `CORE_ALLOW_UNRATIFIED_ETHICS=1`.
`tests/test_medical_clinical_ethics_pack.py` (8 tests) gates the
load-bearing claims:
1. The pack file + mastery report exist on disk and the sha is set.
2. `load_ethics_pack("medical_clinical_ethics_v1")` succeeds (sealed
report verifies).
3. The six commitments are present, with refusal/hedge lists disjoint
and subset of the commitment set.
4. `ChatRuntime(config=RuntimeConfig(ethics_pack="medical_clinical_ethics_v1"))`
composes the manifold with the safety floor *plus* every medical
commitment.
5. The default general pack does *not* carry the medical floor — pack
swap is visible and load-bearing.
## Consequences
**Positive.**
- Deployers now have a worked example to fork. The path is:
author JSON → `scripts/ratify_ethics_pack.py` → drop into config.
- The medical pack exercises all three remediation tiers; downstream
packs can mix-and-match without architectural friction.
- The composition test (`safety ∪ ethics ⊆ manifold`) lifts from
abstract to concrete: every safety boundary plus every medical
commitment appears in `identity_manifold.boundary_ids`.
**Trade-offs.**
- The pack ships with general clinical-deployment commitments; it is
*not* a substitute for a clinician-reviewed deployment policy. The
pack's description states this plainly.
- Six commitments is a starter set, not a comprehensive medical-ethics
taxonomy. Adding commitments later requires re-ratification (the
script is idempotent).
- The `domain` field is constrained to the registry in
`packs/ethics/loader.py` (`general`, `medical`, `legal`, `financial`,
`robotics`, `custom`). Adding a new domain string requires
extending the loader's `_validate_domain` allowlist.

# ADR-0045 — Long-context recall: CORE vs transformer baselines
Status: Accepted (2026-05-17)
## Context
The long-context-cost lane (`evals/long_context_cost/runner.py`)
publishes CORE's vault-recall *latency* as a function of stored-entry
count `N` (linear scan, ~0.22ms @ 1k, ~21ms @ 100k). What the lane
does *not* publish is a comparison against the alternative
architecture every reviewer asks about: a transformer's in-context
recall.
The architectural claim CORE has made since ADR-0001 is that vault
recall is *exact by construction* — `cga_inner` scan over every
stored versor, no approximate index, no embedding compression, no
attention bottleneck. That claim is true by inspection of
`vault/store.py`, but it has not been published as a measurement
alongside the transformer numbers it contrasts with.
## Decision
Ship a deterministic needle-in-a-haystack measurement against CORE's
vault at multiple `N`, paired with frozen citations of published
transformer long-context recall numbers.
### Component 1 — CORE measurement
`evals/long_context_cost/comparison_runner.py` plants a distinctive
versor at a known index alongside `N-1` random distractors, queries
the vault, and asserts `top_k=1` returns the planted needle. Default
`N ∈ {100, 1_000, 10_000, 100_000}`.
Expected recall: **1.0 at every N** by construction. If it ever
drops, the vault has been broken.
### Component 2 — Transformer baselines
`evals/long_context_cost/baselines/transformer_long_context.json`
freezes the comparator numbers as cited published figures:
| System | Context | Reported recall |
|---|---|---|
| Anthropic Claude 2.1 | 200k | 50% (NIAH, no prompt engineering) |
| OpenAI GPT-4 Turbo 128k | 128k | ~71% (NIAH aggregate) |
| Google Gemini 1.5 Pro | 1M | 99.7% (NIAH headline) |
| NVIDIA RULER (eval) | 131k | varies — most models drop below 80% well before nominal context limit |
These are *not* re-measured here. Citations point to the original
vendor / paper. When a new published number warrants an update, the
baselines file is the single edit point.
### Combined artifact
`evals/long_context_cost/results/comparison_v1.json` carries both:
the CORE measurement and the frozen transformer citations, with a
`claim_supported` boolean gating the headline.
`tests/test_long_context_comparison.py` (5 tests) locks:
1. Schema stability.
2. `claim_supported == True` and CORE recall_pct == 100.0 across the
tested N range.
3. Baselines retain `source` + `url` for every entry.
4. The default N range exercises at least 100k.
5. The `core_guarantee` block advertises `recall_kind ==
"exact_cga_inner_scan"`.
## Scope and limits of the comparison
The two components measure different inputs. CORE's needle-in-a-haystack
is over synthetic float32 versors of shape `(32,)`; the cited transformer
baselines are over natural-language needles in natural-language haystacks.
The comparison is at the *architectural* level — exact-scan recall vs
attention-based probabilistic recall — and is not a benchmark-for-benchmark
score.
What the CORE measurement does establish:
1. The `cga_inner`-based recall in `vault/store.py` returns the planted
needle at top-1 for every tested N, at all four scales.
2. This holds independent of vault size up to 100,000 entries (the largest
N reported here; the latency curve in `results/v1_metrics.json` extends
the same primitive to 100k with linear cost).
What the cited baselines establish:
1. Published transformer NIAH recall is < 100% at moderate-to-long context
lengths. Headline figures range from 50% (Claude 2.1 at 200k tokens
without prompt engineering) to 99.7% (Gemini 1.5 Pro at 1M tokens,
single-needle).
2. RULER (Hsieh et al., 2024) shows most open-source models' effective
context length is materially shorter than their advertised limit.
The architectural difference is structural, not benchmark-tuned: CORE's
recall path has no approximation, no index compression, and no learned
component, so its correctness on synthetic versors generalizes to any
content type the vault stores. Transformer NIAH performance is itself
benchmark-specific and varies with elicitation, needle depth, and
context-length stress.
## Consequences
**Positive.**
- The architectural claim about exact recall is now a published
measurement, not a docstring.
- Comparison is honest: CORE numbers are measured here; transformer
numbers are cited from published sources, not strawmanned.
- The needle-in-a-haystack test is structural — any future change to
the vault that breaks exact top-1 recall fails the suite.
**Trade-offs.**
- The CGA inner product for these synthetic float32 vectors can
produce non-finite scores at conformal-point-at-infinity-like
configurations. Scores are sanitized to `null` in the JSON
artifact; correctness (top-1 is the needle) is the load-bearing
signal and is unaffected.
- The transformer baselines are point-in-time. They will need to be
refreshed as vendors publish new long-context recall figures.
- We deliberately do *not* run a transformer head-to-head here. That
would require API budget and harness work disproportionate to the
worked claim. The frozen-citations approach honors the claim
("CORE is exact") without overreaching ("CORE beats every
transformer on every benchmark").

"""Long-context recall comparison: CORE vault vs transformer baselines (ADR-0045).
Two things are compared:
1. **Recall correctness** — CORE's vault recall is exact-by-construction
(`cga_inner` scan over every stored versor; no approximate index).
Transformer in-context recall is probabilistic and is published by
vendors / benchmarks (frozen citations in
`baselines/transformer_long_context.json`).
2. **Recall correctness under controlled needle-in-a-haystack stress** —
ship a deterministic NIAH probe against CORE's vault at multiple N
to demonstrate the correctness claim holds *under measurement*, not
only by construction. CORE's needle is a known versor stored at a
known index alongside `N-1` random distractors; the runner checks
the recall returns the needle at top_k=1. Expected recall: 1.0.
Output: `evals/long_context_cost/results/comparison_v1.json`.
This is ADR-0045's load-bearing measurement: CORE's recall guarantee
is not "probably high" or "high on the cases we benchmarked" — it is
1.0 at every N tested, and the same `cga_inner` math runs at every N.
