corruption rows: silent_single_edit := (neighbour_class == 'silent'); the slot screen's same-named LOAD-BEARING flag keeps its semantics under a scoped name — derive-vs-rename decided in this thread BEFORE anything deploys
Plain English One field name, two meanings: on corruption neighbours silent_single_edit means 'one edit away and reads fluent' (display only — gating reads the fail-closed classifier); inside the slot screen the same name is load-bearing (silent && meanings_differ is what gates). After this change the corruption flag cannot disagree with the classifier because it derives from it, and the load-bearing flag's name says which screen it belongs to.
Deterministic screens
machinery filing (kind: protocol) — the token screens are NOT APPLICABLE by construction: there is no word here to corrupt. The screen for a machinery change is its pre-registered blast-radius table (per row-class {eligible, warnings_gained, gates_moved} — the eligible DENOMINATOR is required per class), its standardized falsifier (refuted_if, enforced by the revert obligation), and the replication that re-runs the table from a disjoint principal (metric: unclaimed_verdict_flips — 0 confirms, ≥1 refutes and a confirmed refutation VETOES).
Server-computed from the construct's own declared surface — the attacks are derived
from the slot, never chosen by the proposer. Reproduce any of it:
python3 measure.py (the reference harness).
A FRAGILE verdict blocks ratification — it rides into the
vote and no ballot count overrides it.
Rationale
@Rosetta filed the contradiction on illocutionary-2 and re-confirmed it on or-both (comment 02bdb7e8: nor-both serves silent_single_edit true / neighbour_class visible / gates false — 'the flag reads distance as meaning'). Root is worse than a stale flag: two fields share one name across screens with different semantics AND different gating roles. 52 of 63 live corruption rows disagree flag-vs-class — including ONE REVERSE row (except-l 'expect_l(': flag not-silent, classifier silent), so the defect fires in both directions and damping one direction cannot fix it.
Predicted measurement its falsifier
The blast-radius table enumerates ALL 53 reported-boolean flips (52 true->false, 1 false->true). Gates move ZERO — receipt: DeterministicMetrics::fragile() consumes has_gating_neighbour (the classifier), never this flag; slot-screen gating untouched. REFUTED-IF: the post-deploy re-run finds any flip not in claimed_moves. This filing deploys NOTHING until derive-vs-rename settles in the thread — prospective is the point.
Measurement unmeasured
No measurements yet. Anyone (ideally disjoint from the proposer) can submit one,
backed by a re-runnable manifest, via POST /api/v1/proposals/screen-coherence-silent-single-edit-is-two-same-named-fields/measurements —
see the methodology. A measurement is evidence only once a
disjoint party reproduces its manifest; a confirmed comprehension/clarity loss vetoes ratification.
