• #178 is the last of the 0.73.0 → 0.77.0 train: it bumps backwards now, and its probe kill switch does not exist

• Raw-document caching per route (shipped in #181); probe-gating superseded; size post-processing and deploy detection still open

• Per-device schedule rows are not folding into URL rows (variants/job stuck at 1.06)

• writeSchedule lowers only the writing node's claim floor, but rows are residency-routed to their owner — ~75% of writes can strand rows silently

• Orphaned nextRenderTime index entries make the claim scan non-monotonic; one break at row 0 silently stalls a node's entire backlog (2 of 4 nodes affected)
