mrwulf 922bd0e8e1 verification: build hygiene, and the hidden dependency it exposed (P0-a)
Phase 0a purges every .olean before compiling, bans stray Lean files at the
verification root (LEAN_PATH contains $PWD, so they join the build unaudited),
and requires gen/ to be exactly the model manifest plus its pinned templates.
The templates are KEPT, unlike SLH-DSA which deletes them: extract.sh directs
the operator to diff the hand-written external models against them, so they are
the reference for that comparison and P2-c will enforce it.

The purge is skipped under --audit-only, which exists to audit the artifacts a
previous full run produced. Those two features would otherwise destroy each
other, and it is a further reason an audit-only transcript is not evidence: it
has not had this hygiene applied.

WHAT THE PURGE EXPOSED, and it is the point of the whole item:

This button had never compiled the corpus from nothing. The signature apex
rests on scalar arithmetic — PointLiftSpec -> ScalarPackSpec ->
ScalarFromBytesSpec, and SigApexSpec -> ScalarDenote — and TWELVE of the scalar
layer's thirteen modules are transitive prerequisites of this manifest. They
were never compiled here. The button worked because check-scalar.sh had run at
some earlier point and left its .olean files behind. .olean is gitignored, so
no git status could ever have shown that the verdict rested on untracked
artifacts produced by a different script.

Nothing about the proofs was wrong. The evidence was resting on something
invisible, for the entire life of these repositories, and it surfaced the
moment something finally cleaned up before verifying.

Those twelve are now compiled here as PREREQ — BORROWED, NOT OWNED.
check-scalar.sh still audits them; Phase 1b asserts every borrowed name belongs
to the other manifest and to neither twice, so the list cannot become a second
ownership claim.

Two consequences fixed along the way, both the spelling-versus-membership error
that ScalarPackSpec has now taught four times:
  - Phase 2b globbed Proofs/*.olean and would have demanded artifacts this
    button never builds. It now scans its manifest by membership and fails
    closed on a missing one.
  - The three inventory drivers were exempted from the dead-file gate and
    compiled in a later phase; after a purge they were absent when Phase 2b
    ran. They are now in the manifest like everything else, and three
    exemptions are gone.

The sweep runner now reports RESOURCE rather than RED when it sees a
memory_exception: lean-guard's clamp is not a broken proof, and it has misled
the operator once and the author once.

Verified green: 8 full runs from completely purged trees — four check.sh, four
check-scalar.sh — zero red, zero resource. Every artifact rebuilt from
committed source. These are the first runs in this repository's history whose
verdict provably depends on nothing but the bytes in git.
