# Architecture Decision Records

This directory contains the Architecture Decision Records (ADRs) for the CORE project.

ADRs record significant architectural decisions: what was decided, why, what alternatives were considered, and what consequences follow. They are permanent records — superseded ADRs are archived, not deleted.

## ADR-0024 chain — Forward Semantic Control closure

ADR-0022 through ADR-0026 form a single coherent chain that closes
forward semantic control as a non-stochastic, replay-deterministic,
trace-evidenced mechanism.  Read in order:

1. **ADR-0022** — Forward Semantic Control.  Establishes the
   `AdmissibilityRegion` data structure (allowed indices, relation
   blade, frame versor) and the contract that a region restricts the
   admissible token set at generation time.
2. **ADR-0023** — Proof Evidence.  Boundary-only proof that the
   admissibility region is honored at the *region intersection* level
   but not yet at the destination-token level.
3. **ADR-0024** — Inner-Loop Per-Rotor Admissibility.  Adds the
   destination-side check: each per-step selection is re-evaluated by
   `cga_inner(versor(candidate), relation_blade) > threshold`, with
   honest refusal (`InnerLoopExhaustion`) when every admissible
   candidate is rejected.  Six phases of implementation evidence
   (Phases 1-6) plus typed `RefusalReason` taxonomy.
4. **ADR-0025** — Rotor / Frame Admissibility.  Adds the rotor-side
   check: when a region carries a `frame_versor`, the rotor's effect
   on the field state (`versor_apply(V, F)`) is additionally checked
   against the frame for positivity in CGA inner product.  Lives in
   `generate/rotor_admissibility.py` — a sibling-but-separate module,
   not in `algebra/versor.py` (would couple algebra to pack state)
   and not in `field/propagate.py` (forbidden normalization site).
5. **ADR-0026** — Ranked Admissibility with Margin.  Replaces static
   threshold tuning with a scale-invariant margin gate: admit iff
   the top blade-score exceeds the second by ≥ δ.  Defaults to
   δ = 0.4.  Falsifiable; characterization documented in
   `docs/evals/phase5_stratified_findings.md`.

Implementation evidence:

| Phase | Commit | Tests |
|---|---|---|
| Phase 1 — pack-grounded fixtures | `3940290` | (rewrites) |
| Phase 2 — typed refusals + trace fold | `310793a` | +10 |
| Phase 3 — ranked-with-margin gate | `639e107` | +13 |
| Phase 4 — rotor / frame admissibility | `542e13d` | +11 |
| Phase 5 — stratified mechanism-isolation | `b664984` | +20 |
| Phase 6 — comparative demo vs baseline | `a076506` | +17 |
| CLI surface (suite aliases + `core demo`) | `36aad75` | +14 |

Runtime contracts for the chain are pinned in
[`docs/runtime_contracts.md`](../runtime_contracts.md) (Refusal
contract, Margin contract, Rotor admissibility contract sections).

## Pack-Layer chain — ADR-0027 through ADR-0045

ADR-0027 through ADR-0045 form the second coherent chain in the
project: a load-bearing three-tier pack architecture (identity /
safety / ethics) with deterministic remediation, full-stream audit,
machine-readable telemetry, an operator-facing CLI readout, and an
investor-facing walkthrough.  Read in order:

| Group | ADRs | What it adds |
|---|---|---|
| **Identity** | ADR-0027 / ADR-0028 | Identity manifold loads from a swappable JSON pack at composition time.  Pack carries `surface_preferences` that visibly drive hedging and claim strength. |
| **Identity surface refinements** | ADR-0030 / ADR-0031 | Depth-language hedge; score-decomposition surface. |
| **Safety** | ADR-0029 / ADR-0032 | Five universal safety boundaries unioned into every runtime manifold; SafetyCheck registry-of-predicates surface (observational). |
| **Ethics** | ADR-0033 / ADR-0034 | Third pack tier — deployment commitments, swappable like identity but propositional like safety; EthicsCheck predicate surface. |
| **Turn-loop wiring** | ADR-0035 | Both checks auto-invoked at end of every turn; verdicts attached to `ChatResponse` and `TurnEvent`. |
| **Remediation tiers** | ADR-0036 / ADR-0037 / ADR-0038 | Safety-only typed refusal → per-commitment ethics refusal opt-in → hedge injection.  Three tiers per ethics commitment: audit / hedge / refuse. |
| **Audit completeness** | ADR-0039 | `TurnVerdicts` bundle + stub-path `TurnEvent` emission + `refusal_emitted` / `hedge_injected` flags.  `rt.turn_log` covers every turn. |
| **Machine + operator surfaces** | ADR-0040 / ADR-0041 | Structured JSONL sink with redact-by-default trust boundary; `FanOutSink` composer; `core chat --show-verdicts` operator readout. |
| **Demo** | ADR-0042 | `core demo audit-tour` — four-scene investor-facing walkthrough; test-gated `all_claims_supported` flag. |
| **Phase-2 measurements** | ADR-0043 | Pack-driven identity-divergence + refusal-calibration runners convert load-bearing claims into CI-enforced numbers across the three ratified packs; combined report at `evals/results/phase2_pack_measurements.json`. |
| **Worked-example domain pack** | ADR-0044 | `medical_clinical_ethics_v1` — six commitments across all three remediation tiers (refuse / hedge / audit); ratified end-to-end through `scripts/ratify_ethics_pack.py`; composes into the runtime manifold alongside the universal safety floor. |
| **Long-context comparison** | ADR-0045 | CORE exact needle-in-a-haystack measurement at N ∈ {100, 1k, 10k, 100k} paired with frozen transformer baselines (Claude 2.1, GPT-4 Turbo 128k, Gemini 1.5 Pro, RULER); `recall_pct=100` for CORE by construction. |

Three sibling pack types compose into every runtime manifold:

```
identity.boundary_ids ∪ safety.boundary_ids ∪ ethics.commitment_ids → manifold.boundary_ids
```

Per-commitment ethics policy lives in two opt-in lists on the
ethics pack: `refusal_commitments` (hard stop) and
`hedge_commitments` (soft prepend), mutually exclusive at load time.
Safety is always in scope for refusal; the floor never moves.

Verification surface:

| Layer | Tests | Live demo |
|---|---|---|
| Identity packs | `tests/test_identity_packs.py`, `tests/test_identity_surface_divergence.py` | `core demo audit-tour` Scene 1 |
| Safety pack + refusal | `tests/test_safety_pack.py`, `tests/test_safety_check.py`, `tests/test_safety_refusal.py` | `core demo audit-tour` Scene 2 |
| Ethics pack + opt-ins | `tests/test_ethics_packs.py`, `tests/test_ethics_check.py`, `tests/test_ethics_refusal_opt_in.py`, `tests/test_hedge_injection.py` | `core demo audit-tour` Scene 3 |
| Turn-loop verdicts + bundle | `tests/test_turn_loop_verdicts.py`, `tests/test_turn_verdicts_bundle.py` | `core chat --show-verdicts` |
| Telemetry sink | `tests/test_telemetry_sink.py`, `tests/test_telemetry_fanout_and_summary.py` | `core demo audit-tour` Scene 4 |
| Audit tour gate | `tests/test_audit_tour.py` — asserts `all_claims_supported` | `core demo audit-tour` |

---

## Pillar 1 → 2 → 3 coupling — ADR-0046 / ADR-0047

ADR-0046 extends the **ADR-0022 → ADR-0026** forward-semantic-control
chain by giving the `AdmissibilityRegion` a new, geometry-derived
source: the `PropositionGraph`.

The graph was previously built **after** `generate()` ran, from the
walk's nearest-node results — a post-hoc descriptor of what the field
had already produced.  ADR-0046 converts each graph's named-node
versors into an `AdmissibilityRegion` **before** `generate()` is
called, via the exact CGA top-k neighbourhood.  The walk is now
constrained by the proposition's geometric meaning rather than
described by it after the fact.

```
geometry (CGA versor neighbourhood)
  → structure (PropositionGraph nodes)
    → propagation (AdmissibilityRegion fed to generate())
```

Three industry-facing demos under `evals/industry_demos/` carry the
falsifiable claims for this coupling.  The exact-recall-at-scale claim
remains under ADR-0045 / `evals/long_context/`, where it is measured
on the real vault path and not duplicated under a weaker construction.

| Layer | Tests | Live demo |
|---|---|---|
| Forward graph constraint (primitive) | `tests/test_graph_constraint.py` — 8 tests | `python -m evals.industry_demos.demo_01_forward_constraint` |
| Forward graph constraint (live wiring) | `tests/test_forward_graph_constraint_wiring.py` — 5 tests | `RuntimeConfig(forward_graph_constraint=True)` then `core eval cognition` |
| Geometry-driven identity | `tests/test_identity_packs.py`, `tests/test_identity_surface_divergence.py` | `python -m evals.industry_demos.demo_02_geometry_drives_identity` |
| Architectural determinism | `tests/test_telemetry_sink.py`, `tests/test_telemetry_fanout_and_summary.py` | `python -m evals.industry_demos.demo_03_deterministic_audit` |

ADR-0047 lands the wire-up behind an opt-in `RuntimeConfig` flag.  The
characterisation it carries (`A/B` on the public cognition split)
shows the wiring is correct and safe but does not move
`surface_groundedness` or `term_capture_rate` on this lane — isolating
the next load-bearing pull to the realizer / surface-assembly path
rather than to propagation.
