mrwulf 049a6f6556 verification: --audit-only mode, and the guard that keeps it from becoming evidence (T1)
Gate work dominates this estate's wall-clock: on 2026-07-29, 3.9 hours of a
session went to Lean re-elaborating proofs nobody had edited while the audit
phases themselves took about fifteen seconds. --audit-only runs every gate
against the artifacts a previous full run left behind: ~60s against ~1280s.

IT IS SAFE ONLY BECAUSE IT REFUSES.

  - It requires every shipped .lean to be BYTE-IDENTICAL to a basis recorded by
    a previous full run. Not mtimes: `touch` defeats those, and a stale-artifact
    check that fails open is worse than no shortcut at all, because a green
    button would then describe a corpus that is no longer on disk.
  - The basis is gitignored build state, so a fresh clone cannot inherit
    permission to skip compiling.
  - The closing banner differs and says in words that the run is not evidence.

selftest-auditonly.sh exercises seven cases: no basis, an edited comment
character, a deleted source, a new source, a missing artifact, a truncated
basis, and — asserted as a PASS — every source's mtime touched with bytes
unchanged, which pins the bytes-not-mtimes decision rather than leaving it
implicit. Negative-tested: with the basis comparison disabled a changed source
is wrongly accepted, exit 0 and zero refusals, so the guard is load-bearing.

A PHASE TERMINATOR, because this broke twice. Every self-test lifts a phase
from check.sh by scanning to the next phase marker. The last phase had no
marker after it, so a lift ran to end-of-file and swallowed whatever was
appended later — first Phase 2c into the axgate lift, then T1's tail into the
binding lift, where it referenced $AUDIT_ONLY and died under `set -u`. Both
surfaced as the BASELINE case failing: a self-test blaming a gate for its own
extraction bug. The phases now end at an explicit sentinel and both lifters
stop there, so nothing appended below can silently become part of the last
phase from a lifter's point of view.

TRUSTED-BASE.md records what an audit-only transcript does and does not
establish, and — because it cost a confusing red run today — that lean-guard's
memory clamp presents as `FAIL: Proofs/<module>` while being a resource
condition, not a broken proof.

Verified green: 8 full button runs (four check.sh, four check-scalar.sh) and 20
self-tests across the four repositories, zero red. One earlier run failed on
the memory clamp because the author ran a test suite concurrently; re-run on a
quiet machine, green.
