- README: pyramid-diagram apex row upgraded to the proven full lift
(accepted <=> decompress(R) = [k](-A)+[s]B), status table names all
four button-enforced tiers, apex section gains the phase-2 tier table
(half-lift / point equation / full lift) + the decompress-chain
summary; source pin updated to the pushed patch commit.
- TRUSTED-BASE item 5: rewritten from the single byte-apex certificate
to the FOUR enforced tiers (decompress_of_canonical noted as
standard-three-only).
- gen/CurveField/FunsExternal.lean: stale root-namespace
edwards.decompress.step_1/step_2 axioms removed (dead weight left
behind by un-opaquing; outside every cone, but they forced
fully-qualified unfolds - see control FAILURES.md).
- check.sh Phase 3b success echo aligned to "apex + full-lift" (echo
only; the enforcing greps covered all four tiers already).
Validated by the pass-4 sweep: 9/9 buttons green (this repo's check.sh
+ check-scalar.sh among them), logs retained in the pass workspace.

- README: the pyramid diagram claimed the cofactored ZIP-215 equation,
which is NOT the proven statement - corrected to the actual theorem
(accepted IFF compress([s]B-[k]A) = R, byte-for-byte) and the signature
row now names verify_accepts_iff; new "The signature apex (phase 1)"
section states the theorem, this repo's glue architecture, the exact
button-enforced axiom cone, and the phase-2 deferral.
- TRUSTED-BASE: item 5 rewritten from an aspirational hash paragraph to
the structural boundary - certificate name, exact allowed cone, and the
Phase 3b enforcement that fails the build on any deviation.
- Dead pre-merge artifacts removed: gen/CurveScalar, CurveScalar.llbc,
extract-scalar.sh (the merged gen/CurveField universe is the single
model; check-scalar.sh remains the scalar button, header updated).
- lean-guard: Guard 3a retry ladder (LEAN_MEM_WAIT_SEC) - a clamped run
that dies on memory retries as headroom improves, converting ambient
memory pressure from a deterministic abort into a delayed pass.
Fresh green buttons after these changes: check.sh (incl. Phase 3b apex
audit) + check-scalar.sh, both at shipped defaults, coherence pass 3
sweep 2026-07-05.
