S7 Fable re-audit: close the cone-audit COVERAGE gap (52/52), verify button by exit code

Browse source 
Re-derived S7 as Fable, practicing the standing rule (check exit code +
ALL GREEN, not tail). Confirmed committed button genuinely exits 0.

FINDING: the cone audit had a COVERAGE gap — 34 of 52 proven objects
were pinned; 18 (incl. core defs kbelow/hleaf/hnode and the pin-store
defs pinAccept/pinExtract/acceptCons, plus intermediate lemmas) were
never cone-audited. Transitively safe (Phase 1 forbids axiom under
Proofs/, Phase 2 forbids sorry, universally) — but 'transitively
covered' is not good enough for an externally-reviewed corpus. Closed:
every proven theorem/def now has its EXACT cone pinned, read from
#print axioms (not guessed). Coverage now 52/52, empty unaudited list.

Cones of note: hleaf/hnode = [LTLAcc.sha256] only; kbelow and the pure
arithmetic/list helpers = no hash axiom; the def-level objects that
touch MTH carry the single sha256 boundary. No surprise axioms anywhere.

Button verified: EXIT 0, ALL GREEN, FIDELITY GREEN, 164,479/164,224
pinned. LTL untouched.
