Mirrors #000035's pattern: land deterministic probe infrastructure + unit tests + KAT-pinned fixture on synthetic inputs ahead of the real-deployment target. v7 plastic-training has no representative checkpoint today (per §5 risk + §7 status); Phase 1a closes that gap by giving the probe a synthetic test surface that's verifiable end-to-end without waiting for v7 ramp-up. What §7 now proposes Phase 1a lands: 1. ``bench/scripts/phi_alignment_probe.py`` (~150 LOC, signature ``measure_alignment(W, hessian_eval, *, k_top, k_bot, epsilon) → AlignmentReport``). Lanczos top-k + bottom-k via scipy. 2. ``bench/fixtures/phi-alignment/synthetic-checkpoints.jsonl``: ~30 deterministic-seed (W, H) pairs across three classes: aligned (engineered W in low-λ subspace → expect STRUCTURAL_ALIGNMENT), uniform (Gaussian W per v7 reference → expect NO_ALIGNMENT), anti-aligned (W in high-λ subspace → expect ANTI_ALIGNED). Same KAT-regression discipline as #000035's phi_prg fixture. 3. ``tests/test_phi_alignment_probe.py``: round-trip determinism; verdict thresholds; Lanczos convergence vs dense decomposition on synthetic Hessian; module export shape; KAT regression. 4. New ``[hessian]`` optional-dependencies block in pyproject.toml (numpy>=1.26 + scipy>=1.11). Same gating as the existing ``[math]`` block for sympy — keeps core install lightweight. Tests fail-soft via ``pytest.importorskip`` when absent. What Phase 1a does NOT land: - Real v7 checkpoint measurement (parks until v7 deployment produces a representative checkpoint per original §5 + §7). - M1 / M2 implementation (separate tickets). - Adversarial-training experiment (out-of-scope per §4). Phase 1b (real-checkpoint measurement) preserves the original §7 closure criterion: ticket closes when a v7 checkpoint produces a verdict resolving §9.1 of the soft-hash-channel analysis. Phase 1a is prerequisite infrastructure, not closure. This is doc-only — no code change in this commit. fox decision needed before Phase 1a implementation lands. |
