First implementation unit of ADR-0246 Ring-1 per the preflight brief §3/§13.
Promotes the induced-action apparatus from the slice-0 eval prototype into pure,
tested geometry — the single source of truth both the future gate surface and the
§11 grounding-feasibility study will consume.
core/physics/identity_manifold.py:
+ induced_action(versor) A(F) = G^-1 · <a_k, F a_j F~>_0 (§3.1)
+ orthogonality_defect(versor) d_orth = ||A^T G A - G||_F (§3.2)
+ typed_residual_energy(versor) e4/e5/spatial_foreign/unclassified (§3.6)
+ orthogonality_defect_of_action / SPATIAL_GRADE1_INDICES / E4,E5 index pins
core/physics/identity_action.py (new, pure):
+ IdentityStabilizer (locked singleton H_id={I}, §3.3)
+ stabilizer_defect d_stab = min_H ||A - H||_G (§3.2)
G-weighted norm reduces to Frobenius at G=I (default pack)
evals/adr_0246_mismatch_diagnostic: rewired to delegate to the canonical
primitives (removes the duplicate prototype copies; drops unused import).
Scope: off-serving (algebra-only, A-04 quarantine, pinned by test); no gate,
threshold, axis, H_id, corrector, or flag change. identity_wave_gate stays
default-off. Path ledger (§3.4/3.5), gate admit surface (§3.7), and the eval
matrix + §11 feasibility study are subsequent units (brief §0a records the
sequencing). No self-Accept.
[Verification]: uv run core test --suite smoke -q => 176 passed;
tests/test_adr_0246_induced_action.py 12 passed (RED-first);
identity surfaces (mismatch-diagnostic rewired, identity_manifold, identity_gate
wave/runtime/eval, gamma_calibration) 87 passed.
