check.sh pipes lean-guard stdout to /dev/null, so the headroom-clamp warning
was invisible: on a loaded desktop (4.3GB avail) the clamp cut -M 4096 to
1263MB, TypesExternal died loading imports, and the bare FAIL read as a proof
regression. All human-facing diagnostics (floor refusal, clamp, TIMEOUT,
KILLED) now go to stderr, and a clamped memory-death prints an explicit 'this
is an environment condition, not a proof failure — free RAM and re-run' note
with the required headroom. Reproduced and verified through the >/dev/null
pipe. Infra only; no proof, model, or gate change.

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).
