saymrwulf 5f785a75a3 coherence pass 2: restore the one-button property, institutionalize audits
- check.sh: proofs memory default 6144 -> 8192 (ReduceSpec's norm_num
  step peaks above 6144; guard aborted gracefully — R3 was broken, S1
  held). Matches pasta's calibration.
- check.sh: dead-file gate now exempts Scalar* (delegated to
  check-scalar.sh); the gate had been un-passable since the scalar layer
  landed, masked by the memory failure.
- check.sh: axiom-audit phase routed through lean-guard (cgroup + flock;
  was raw lean -M), audit temp file moved into the workspace (lake env
  rejects /tmp inputs — the /tmp phase had never run green).
- check-scalar.sh: NEW Phase 3 kernel axiom audit — ScalarProofs.L_val
  must report exactly [propext, Classical.choice, Quot.sound].
- README: signature layer ' planned' (was 'in progress' with nothing
  started); planned certificate names marked as such.

Validated: full check.sh + check-scalar.sh green end-to-end in the pass-2
sweep (see formal-verification-control/COHERENCE-PASS-2.md).
