REVIEWED-87's original entry (PENDING-99, the fidelity_equivalence@3
design-gate ruling of 2026-08-05) was replaced this afternoon by the
PENDING-111 amendment block placed at the same heading. The amendment's own
"**Amends:** REVIEWED-87" line then pointed at a record no longer in the
file, and the register could no longer answer what was ruled under 87 — the
register's whole job.
Recoverable, and recovered: the entry was intact in git HEAD and the
underlying jurist ruling is separately filed at
studium-engine/docs/quoted-tier-acceptance-JURIST-RULING-2026-08-05.md. But
the register entry uniquely held Q2's reframing (the route to PENDING-100),
Q3 REJECTED and its strengthened basis, Q5 CONCUR D-1, and the finding that
"the decisive sentence was one the executor had read and not surfaced, which
a verbatim-containment check passes every time."
CAUSE, and it is the executor's. The handoff draft was headed
"## REVIEWED-87 — AMENDMENT 2026-08-07" and described as "the block to
place", with no instruction that it join rather than replace. That reads as a
replacement heading, and the steward's reading of it was reasonable. The
copy-paste-clean discipline exists so a placement cannot be ambiguous, and
this draft was ambiguous.
NOTHING DETECTED IT. It surfaced because a diff was read by hand and the tell
was a deletion count on what should have been a pure append. This is
`removing-a-claim-is-not-removing-the-reliance` at the governance layer: the
amendment's dependency on the original survived the original's removal and
became invisible.
Check 7 added to governance-drift-check.py, which already runs at every wake:
every `## REVIEWED-N — AMENDMENT` requires an un-amended `## REVIEWED-N`
entry, and every `**Amends:** REVIEWED-N` must resolve. Reported separately
from the CLAUDE.md findings so that report's own claim stays true.
Controls per the standing epistemic standard, and the third is the lesson of
the day — a check that has never fired on a known-bad input is unestablished,
so the instrument is run against a synthetic reproduction of the actual
failure. Red-witnessed on a copy of the live file with the deletion replayed:
fires both findings. 11/11 controls pass.
Detection only. REVIEWED.md is [ESCALATE], the steward's hand
(Constitutional Constraint #1); the restoration above was placed by the
steward, not by the executor.
