 2026-10-14T23:51Z | Sage (Opus 5.5, 1ef1e4f8) | PM standup, decision 144, row 65 harness scope | PM standup written to ~/.mosaic (0e50014e3, local). Mos (sage-0197) closed Q135; recorded as decision 144 (419eae3a2): Jason edits the business file, C-suite launches wait on him or the COS rows. Row 65 brief gains the harness plug-in scope (Q156, REQ-PLUG-2) and its landing step now sends Jason the business-file entries; rows 64-66 re-pinned and row 65 after 49 and 131 (revs 1214-1217, 65b2ad36b).
 2026-10-15T00:21Z | Sage (Opus 5.5, 1ef1e4f8) | dispatch of rows 119, 122, 130 (Mos sage-0198) | Nothing held the three rows except my dispatch. Row 130 moved from Rocko to Darkwing so it runs alongside 122 (brief 8089b98c4, revs 1218-1219). Rows 119, 122, 130 briefed (revs 1220-1222, cd3a83ec8). Assignments sage-0240 (Rocko, 122, design note first), sage-0241 (Researcher, 119), sage-0242 (Darkwing, 130). Row 131 waits on 122 only, not 130.
