This is a quality-control route, not a mathematical one. It changes no rung of any claim by itself; it changes what an embedded PASS is allowed to mean. Rung of the observation behind it: **verified** (three accepted returns, quoted below). Rung of the route's payoff: none until a validator is audited.\n\n## The observation, from three lanes\n\nThree accepted break returns on three unrelated documents each found a served check that cannot fail on the data it is given:\n\n- Return #25 (`research/verify-ladder.js`): the \"survived\" column is computed as D − new and so restates D = (p−2)·D_prev rather than checking it; the Seam Lemma checks to folds 997 and 9973 have no refutation power for any odd prime.\n- Return #28 (`research/exact-g2-ladder.js`): the header's claim that section 3 \"FAILS if the arithmetic is done in Number and passes only in BigInt\" is false for the file's own data (every certificate holds in Number); the phase-1 validation of the run filter ran at THRESH = 1, where the filter is vacuous; the filter code is not served.\n- Return #31 (`research/grouped-divisor-validation.js`): eleven of twelve single-edit mutants (a cut deleted or moved) leave the served validator passing, because the archived partition asserts inclusion–exclusion, an identity true for any three sets, and the `droppedVerticalCut` control is incremented unconditionally; the vertical half of cut C has empty support at every retained scale.\n\n`research/qc/embed.js` documents its own scope: the OUTPUT block proves the output came from the code and \"says nothing about whether the code is right\". The calibration legend's rung \"verified: a finite computation ran and matched\" has no clause about what a wrong input would have produced. No standing rule requires a validator to fail on a corrupted input: grep of `research/OUTCOMES.md`, `research/RESEARCH-EXECUTION.md`, `research/README.md`, `research/qc/README.md`, `qc/embed.js` and `qc/questions.js` for \"mutant\", \"cannot fail\", \"self-check\" gives zero hits (\"negative control\" appears four times in OUTCOMES.md as per-attack counts). This route is not in the \"Closed routes\" register (115 rows read today); it is not a route to the conjecture and does not claim to be.\n\n## The route\n\nOne return per served validator (`research/*-validation.js`, `research/verify-*.js`, `research/exact-*.js`, `research/qc/*.js` with embedded PASS lines), each shipping:\n\n1. A mutant table: for every assertion the validator prints as PASS, one single-edit corruption of the input or of the checked constant that ought to make it fail, with the observed exit code and whether stdout changed. Return #31 section 2 is the template (twelve mutants, two caught).\n2. For each assertion no mutant can make fail: either a patch that replaces it with a named assertion that flips at the boundary (return #31 section 6, mutants P01–P09 all caught after the patch), or a one-line statement in the validator's header that the check is custody only.\n3. A re-embed of the OUTPUT block where code above the banner changed (`node research/qc/embed.js --force`), so the served hash stays honest.\n4. A one-line edit to the calibration legend (`CLAUDE.md` or wherever the legend is served) once three such returns are accepted: \"verified\" for an embedded PASS requires a mutant table on record.\n\nOrder of attack: the validators that carry a PROVEN or VERIFIED rung in `research/G2-STATE.md` or in a paper first, since a vacuous check there props up the highest rungs. Cost: return #31's twelve mutants took one session; a validator of ordinary size is one assignment at 2 h.\n\n## What would kill it\n\nA served rule that already requires mutant evidence (none found today); a reading of the legend's \"matched\" that already excludes vacuous checks (the text does not say so); or a survey showing the three cases are the only ones, which would make this a three-line audit rather than a lane. The survey is the first return of the route either way.\n\n## Sources\n\nReturns #25, #28, #31 (@Benjaminsen, break, accepted), sections quoted above; `research/qc/README.md` and `research/qc/embed.js` (served 2026-09-11); `research/OUTCOMES.md` \"Closed routes\" from line 2712; `research/README.md` lines 127–130.
