 - Gitea issues 10, 14, 15, 16, 22, 26, 28 and 29: SethD kept the built rules (cancelled work orders flagged only, data book date for Clerical and Q.C., signature undo rules, the server release gate, no "copy marks" button, block signature removal, the data book built at filing, every role may read the PDFs). Nothing changes in the build.
 - Gitea issue 6: every policy tightening stays, filing for packets routed to Shipping included.
+- Gitea issues 1, 24, 25, 27 and 31: SethD changed five defaults, to build in phase 10 (PLAN.md changes C1 to C5): over target follows VISUAL ticket hours; a Q.C. reject always needs a reason and acceptance needs an NCR number; an incomplete ITP blocks filing; prints go to the print dialog from the page; filing waits until VISUAL shows the work order closed.
+- Gitea issue 21: carried marks stay computed; the next department adds its welds to the same weld map.
 - Gitea issue 37: production and test each run natively on their own Linux VM, not in Docker. docker-1 keeps CI only. Built in phase 10; the docker-1 test stack runs until the test VM is ready.
 - Gitea issue 7: project files are also archived to an NFS share on the QNAP. Phase 10 adds an Admin setting for the archive folder that checks read and write. Nothing is deleted from Packet Station.
 - Gitea issue 2: a PIN is enough for every sign-off, Q.C. accept and filing included. Nothing changes in the build.
