Round-9 swept all ten instruments per fork instead of only the two buttons,
and found selftest-axgate.sh red in all four. Root cause, identical to the
KERNLOG defect fixed the day before: a self-test lifts one phase out of
check.sh and supplies its variables from a HAND-WRITTEN preamble, and the
phase later grew a dependency nobody told the preamble about.
Phase 2b stopped globbing Proofs/*.olean and started reading $PROOFS by
membership. Bash does not error on an unset array under `set -u` — it
expands to nothing — so the gate silently received
expected := [".olean"]
one entry with an empty name, and rejected the baseline via its own
fail-closed absence check. Exit code right, reason wrong.
· lift-guard.sh (new, pinned): derives every variable the lifted payload
reads, subtracts what the driver defines, and fails AT LIFT TIME naming
the remainder. Wired into all five lifting self-tests; selftest-shapes.sh
drops its inline copy. One implementation, not five, since drifting out
of sync is the entire failure mode.
· selftest-axgate.sh: lifts PROOFS verbatim, and its case 2 now poisons a
MANIFESTED leaf module rather than adding a stray file. The stray-file
attack was a no-op against membership semantics — that is the dead-file
gate's job, proven by selftest-harness case 8 — and it is also the
weaker attack, since adding files to Proofs/ must clear a gate that
editing an already-manifested module does not.
· Phase 2c's accounting identity moves behind its own marker with its own
ACCTFAIL verdict, so the phase is liftable by construction rather than
by a self-test knowing where to stop. Truncating the lift range alone
would have dropped Phase 2c's own verdict and left the test unable to fail.
· The other four lifting self-tests assert on the PAYLOAD rather than the
assembled driver, so a marker in the preamble cannot satisfy a check
meant to prove the lift landed.
Certified: 8/8 self-tests green in all four forks (~212 assertions, none
failing); check.sh bytes unchanged and still matching the pin written before
the 3h08m round-9 sweep, whose 36 GREEN button rows therefore stand.
--audit-only re-run against the new HARNESS.sha256 in every fork.

Phase 2c exists because a source-regex enumerator proved evadable in
ltl-accumulator-verified: attributed, private and `instance` declarations
and a nested-namespace basename collision all slipped past it. The fix was
to stop reading source text and ask the Lean environment, and that fix was
ported here. But a fix ported is not a fix tested. selftest-inventory.sh
proves the GATE reacts to a difference; it feeds synthetic observations and
never runs the walker. Nothing here had ever asked whether the WALKER SEES
a declaration written in an evasive shape.
selftest-shapes.sh adds all four shapes to an audited module, recompiles it,
runs the real Phase 2c, and requires each one to be NAMED in the
UNCLASSIFIED list. Asserting that the gate merely failed would not do: one
shape surfacing fails the run while the other three ride along unseen. All
four forks report all four. Negative-tested by removing the injection — the
run then reports the walker blind and fails.
The victim module is derived from each repo's own manifest, not named: the
forks do not share a corpus (dalek/anza attack Proofs.Basic, risc0/betrusted
Proofs.DecompressMain), and a hard-coded name would have silently found
nothing on half of them. It must be manifested, must not be an inventory or
audit driver, and must be imported by no other manifest module.
Two notes for whoever edits this next. When re-deriving a leaf module, the
inventory drivers must be excluded from the set of IMPORTERS as well as from
the candidates: they import the whole corpus, so leaving them in makes every
module look imported, finds no leaf, and the test silently has no victim at
all. And a lift of Phase 2c needs SCALAR_SH/SCALAR_MANIFEST alongside
PROOFS, or the coverage check dies on an unbound variable.
New executable pinned in HARNESS.sha256. Certified by a full sweep: both
buttons, all four forks, purged trees, machine otherwise idle. 8/8 green.
