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

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 They are permanent records — superseded ADRs are archived, not deleted.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:
- ADR-0022 — Forward Semantic Control. Establishes the
AdmissibilityRegiondata structure (allowed indices, relation blade, frame versor) and the contract that a region restricts the admissible token set at generation time. - 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.
- 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 typedRefusalReasontaxonomy. - 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 ingenerate/rotor_admissibility.py— a sibling-but-separate module, not inalgebra/versor.py(would couple algebra to pack state) and not infield/propagate.py(forbidden normalization site). - 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.

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.

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.
