2026-08-31 — Degrade itd-185's four semantic supply-regime signatures

2026-08-31 — Degrade itd-185's four semantic supply-regime signatures (RG-EVAL-ORDERING, RG-EVAL-RECOMMENDATION, RG-REG-FIXPROPOSAL, RG-EXPL-DISPOSITION) from enforce to flag: a hit raises a review flag on the run record and the item lands. This is the reserved degradation path spc-63 names, taken deliberately, and it weakens the claimed property from ENFORCED to OBSERVED. The structural halves are untouched and stay absolute — the reserved names and the strict per-position schema still refuse. THE EVIDENCE IS SYNTHETIC, and saying so is the point: the itd-185 fidelity audit constructed a corpus of 34 realistic reading outputs and 14 were caught, every one of them for REPORTING what the read document said rather than for proposing anything (the disposition detector fires on any claim quoting the token this repository's records carry everywhere; "section 3 says the fix is already merged while section 8 says it is pending" is the canonical shape of a detection finding and fires too). No reading has ever been run through this verb — every payload the delivery has validated is synthetic — so the ruled condition, "degradation only on observed noise" (BUILD-PLAN.md:70, spc-63), is NOT met and this departs from the ruled design. Taken anyway because the alternative departs further: the gate is currently enforced over a calibration that has never been taken, which is the standing tension itd-185 already records against widen-options' "calibrated before it gates", and waiting for observed noise means enforcing indefinitely on no calibration, because the assembled input is about 9.8 MB and cannot be handed to a reading at all (iss-2608311501186646). Of the two departures this one cannot produce a false refusal of a real reading, and it is reversible by the same one-line mode change. REVISIT POINT: the first real reading. When the instrument can be run, the flags it raises are the observed calibration, and the mode is reconsidered on that evidence rather than left at flag by default. Rejected: keep enforcing — defensible under the letter of "degradation only on observed noise" and indefensible under "calibrated before it gates", and on the synthetic evidence it would refuse roughly two in five legitimate outputs the first time a reading ran. Consequences recorded in the same change: TestEverySignatureShipsEnforced is replaced by a test pinning each entry's mode by name so a silent flip in either direction fails; itd-185's ac-5 and ac-9 are rewritten to say flag rather than refuse; the ingested audit verdict rcp-fe3450ca55ff records those two criteria MET on the strength of a refusal and therefore describes superseded behaviour needing re-issue at the next audit; and the disclosed residue on itd-185 and spc-63 is widened to name over-catching beside under-catching, with the propose-versus-report distinction as the reason.
