The skeleton-era docs said 'six hash oracles' including prf — written
before the cone analysis showed prf/prf_msg are sign-side only. The
extracted model and FunsExternal carry exactly FIVE oracle axioms
(h_msg, f, h, t_l, t_len); the documented boundary now matches the
real one in README, TRUSTED-BASE, and extract.sh. Caught by the
post-flip drill's cross-consistency pass.

Subject pinned: integritychain/fips205 @ 30bac08 via
saymrwulf/fips205-source @ 5dca0db. Parameter set SLH-DSA-SHA2-128s.
Scope: verify path only (slh_verify -> ... -> chain); six SHA-2 hash
oracles opaque per the standing boundary.
Gate-0 record (2026-07-22): charon clean on the full verify cone;
aeneas translates everything except the Hashers fn-pointer struct
(3 unique errors, the sole obstruction) -> phase 1 = named-opaque-
free-function compat patch in the snapshot repo, the established
dalek sha512-shim pattern.
check.sh exits non-green and says NOTHING PROVEN YET (H5, R3).
lean-guard copied; every future compile runs under it (S1, S2).
