fix(cognition): pre-stage land repairs after L2/PASSTHROUGH excision

Close residual failures from geometric sovereignty hardening without
restoring scalar-L2 or PASSTHROUGH authority:

- Ratify CORRECTION/COMPARISON via vocab-grounded tag and multi-token
  subject anchors so teaching capture and cognition intent accuracy hold.
- Keep observational wave leakage from vetoing teaching while
  identity_wave_gate is off; syntactic override still rejects.
- Surface GoldTetherViolationError as fail-closed tether residual rather
  than aborting lifecycle observation.
- Replace excised legacy identity-eval path with a geometry-blind baseline.
- Align sensorium corridor and lift instrument assertions with sandwich
  unitary close and honest PARITY when baseline already solves.

[Verification]: smoke 176 passed; cognition 122 passed 1 skipped;
teaching 109 passed; claim batch 34 passed
