Hold/release rewrites OCRH.DCSTAT and DCHREA without touching any date column, so no watermark could see it. A full-table row diff of LGDAT.OCRH vs cms.ocrh (468,823 rows both sides) found 168 drifted rows, 0 missing, 0 extra -- and 159 of them changed with no date moving at all (checked dcudat/dcodat/dccdat/dcmdat/dchdat/dcxdat/dcsdat/dcmxdt). 155 of the drifts were DCSTAT, 4 DCHREA. Every drifted row was still open (DCSTAT in A/N/H/B); none had reached 'C'. Only ~2,044 of 468,823 orders are open, so re-pulling the whole open set each run is cheap and catches 100% of the observed drift. Applied to ocrh and to the two modules that read its changed-set, ocri and ocrs. Result: drift 168 -> 11 rows, DCSTAT 155 -> 3. No invoice-driven branch: tested against LGDAT.OCRHT (CMS's header change log, keyed DC3TMSP-leading via logical OCRHTX1) over the live watermark window -- 1,107 headers changed, 65 missed by the date branches, 0 missed by dates+open, and a 5- or 30-day invoiced-orders branch added exactly 0. Closing an order writes dcudat/dccdat, so the date window covers the flip. Also evaluated LGDAT.OCRIT (the order-line change log) as a replacement for the open-order branch and rejected it: at the live 8-day watermark it reports 0 changed orders not already caught, at ~12x the predicate cost, and its lower row count means it declines to pull 18k lines the open set would -- safe only if CMS's logging is complete, which is unverified.
