Phase 2 — Corpus observation runner (inner_loop_runner.py):
- Four-condition matrix: boundary_only / null_control / inner_loop_t0 / inner_loop_tpos.
- Added `inner_loop_force_admit` to generate() — exercises the inner-loop
code path but force-breaks on first candidate. Eval-only null control:
isolates rejection as the causal factor for any pass-rate delta.
- Metrics: pass_rate, mean_rejection_count_per_turn,
non_empty_rejected_attempts_rate, exhaustion_rate (gated at 5%),
mean_admissibility_checks_per_turn, mean/p95 added_latency_ms,
trace_hash_stability across 5 reruns per case.
- Finding on v1+dev: causal_attribution_valid=True, code_path_residual=0.0,
but exhaustion_rate=0.33 at t=0 — chain outer-product blade is
geometrically blind to the active pack.
- Tests (tests/test_inner_loop_phase2.py, 5 pass): pin
causal-attribution and live-corpus trace-hash stability invariants.
Phase 3 — Mechanism-isolation v2 corpus (5 cases, v2_runner.py):
- Synthetic adversarial cases with controlled geometry — each case
specifies seed_token, admissible_tokens, relation_blade_token, and
admissibility_threshold. Field state is constructed directly from
the seed token versor, not via priming.
- For every case: boundary-only selects the forbidden decoy and
inner-loop selects the expected endpoint with the forbidden token
appearing in rejected_attempts.
- Result: mechanism_isolated=true on 5/5. boundary_decoy_rate=1.0,
rejection_traced_rate=1.0. Inner-loop rejection is demonstrably
doing causal semantic work on real packs.
- Tests (tests/test_inner_loop_phase3.py, 8 pass): GATE on
mechanism_isolated.
Phase 4 — Threshold characterization (threshold_characterization.py):
- Distribution mapping per-case AND globally on v1+dev, v2, combined.
- Per-threshold sweep over [-1.0, -0.5, 0.0, 0.1, 0.25, 0.5, 1.0].
- Finding: per-case geometry separates cleanly (correct_min > incorrect_max
on every v2 case), BUT no global static threshold passes the
separation_quality >= 0.8 gate. Blade norms vary ~10x across cases.
- Static thresholds (global, relation-typed, or constant frame-derived)
are geometrically insufficient. Per-case-normalized thresholds
(e.g. fraction of blade self-score) are the recommended next step.
- v1 chain-token outer-product cases all skipped — the corpus's chain
tokens (alpha, beta, gamma, delta) are not grounded in the active
pack. Load-bearing finding for ADR-0025 region construction.
- Tests (tests/test_inner_loop_phase4.py, 5 pass): pin the finding
diagnostically (not gated).
Phase 5 — ADR-0025 design note (draft):
- No code changes proposed. Scopes three architectural questions:
(1) home (algebra/versor.py vs field/propagate.py vs generate/) —
preliminary stance: algebra/versor.py.
(2) threshold scheme (blade-normalized fraction recommended over
static; learned/adaptive rejected for determinism).
(3) teaching-loop boundary — Stance A confirmed: rejections are
runtime hygiene only, no entanglement with teaching/*.
- Decisions to be closed before Draft → Accepted.

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.

Session logs record the decisions and rationale from individual working sessions. They are not ADRs — they are the narrative record that informed the ADRs.
