The supersession declared pin 0's "no mechanism to detect a
reduction-semantics change" false because version mismatches are now
rejected. That conflates two different claims, and it contradicted this same
contract's requirement 3 thirty lines below, which says no mechanism can
detect a missed bump. CLAUDE.md, the handoff, and epiphany-ops's own
authority doc all state the correct version.
Only one of the two claims moved:
- Declared-version mismatch -- a base whose recorded
reduction_algorithm_version differs from the running authority -- is now
ENFORCED, refused with CanonicalBaseRequiresRebuild on read and write.
- A semantics change is STILL UNDETECTABLE. Nothing compares the semantics
the code implements against the number it declares, and nothing can.
So S27's enforcement is conditional on the bump discipline, not a substitute
for it. If this rung changes CreateStaffGroup's verdict and the bump is
missed, every base it produces declares 0, matches an authority still reading
0, and passes every check S27 installed -- the enforcement fires correctly on
a number that is itself wrong. That is exactly why pin 0's requirement 3
inverts into a mandatory bump rather than dissolving: S16's bump to 1 is the
human-enforced half of the guarantee, and the only half that applies to
itself.
Changes:
- The falsified-claims table splits the row in two: the accepted-stale-base
consequence is false now; the no-detection claim is marked STILL TRUE.
- New "Enforcement is not detection" section states the split as a table so
the two cannot collapse into each other again.
- The discharge marker before pin 0 no longer lists no-detection among the
falsified claims and warns not to read the discharge as closing that gap.
- Pin 11's retained blockquote had the same defect: it was annotated "every
claim in this quoted block is now false," but "no mechanism comparing
either against the semantics it actually implements" is still true -- S27
compares a declared number against a declared number. Annotation now
separates what is false from what stands.
