 2026-11-06 | mvp3-archive-child (#797 lane) | feat/mvp3-project-archive from 05fdfef9e: owner-only project.archive/unarchive (schema 3s→3t project_archives journal), project.list includeArchived, archived-project refusals on thread/room sends, Console archive UI (new project-archive files), CLI project archive/unarchive/list --archived, restore-guard lists | bus 1601/1601 (Node 24; Node 26 pre-existing socket stall), webui 582/582, plugins 132/132, cli 1191/1194 with two pre-existing load flakes (row253 C4 timing, land_work; both pass isolated, base full-suite fails four of the same family); committed locally, not pushed; report /mnt/storage/scratch/mosaic-lead/mvp3/project-archive-r1-report.md
 2026-11-06 | mvp3-archive-r2-child (#797 lane) | feat/mvp3-project-archive-r2 from 3e21d239b: close archived thread/session and product/request/PRD/task/bootstrap/manifest admissions; preserve accepted completion, cleanup and reads; repair archived navigation and two-hook styling | bus 1618/1618, WebUI 583/583, other consumers 230/230, lifecycle/launch 67/67; CLI path run 585/587 with both dependency-fixture failures reproduced then superseded by whole-file case2-install 28/28 after self-link cleanup.
