mrwulf 2da0a79981 Review round 4: F1* absorbed (lied-size boundary), acceptCons_sound, kit reproducibility
Round-3 verdicts: GPT-5.6 conditionally approves (blockers closed, one
portability finding); the Claude reviewer's Socratic addendum produced
F1*, the strongest finding of the series — deployed verify_consistency
and mechanized ConsRec are NOT extensionally equal. Reproduced exactly
(witness verify_consistency(1,3,R2,R3,P(2→3))=True vs ConsRec reject;
3,405 divergences n<60; strictly one-sided; power-of-two seeding
mechanism confirmed in source).

- KNOWN-GAPS gap 14: witness, mechanism, one-sidedness, and the
  pinned-pair side condition under which Theorem 3 transfers to the
  deployed verifier (pacta's pin-store flow supplies it by
  construction). No pacta code change; deployed behavior matches
  upstream RFC 9162 implementations.
- fidelity: lied-size family — 73,573 boundary cases, 3,867 expected
  divergences PINNED, one-sided direction asserted per case. Banner
  rescoped: agreement over pinned families, not extensional equality.
- Theorem3.lean: acceptCons_sound (F2) — soundness over the named
  acceptCons predicate, n₀=0 discharged from the non-prefix premise,
  size bound derived from acceptance via new consRec_some_le. Cones
  read from #print axioms; CONES/AxiomCheck/allowlist updated
  (218 → 222 constants, diff = the two theorems + two generated
  auxiliaries).
- F3/GPT§7: verification/lean-toolchain pin + run_bare.sh (reviewer's
  standalone runner, plain public lean — verified green: 61 cones, 222
  constants, gate green) + AENEAS_ENV override in check.sh and
  selftest_audit.sh.
- F4: awk field-equality replaces regex-with-dots in Phase 3b.
- F5: git-tracked .pyc removed (worse than reported — it was in the
  repo, not just the kit); __pycache__ gitignored; round-4 kit ships a
  corpus MANIFEST.sha256 + pinned commit (also GPT's governance
  condition).

check.sh exit 0, ATTESTATION GREEN; selftest exit 0, 9/9 + control.
Live LTL untouched (12 leaves, bcd15f9d…); attestation still gated on
ePrint decision + author review + explicit operator order.
