Purpose

Records everything that landed on main since #677 in the devlog and the backlog. It also moves completed work to the backlog's Complete section, instead of leaving it deleted or described inline.

Changes

• Devlog
  • A new October 6 entry covers the 20 PRs merged that day, [ai][go][docs] l1packets: read PCAP packets in place #679 to Bump the "documentation" group with 1 update across multiple ecosystems #703. The open [ai][go][js][docs] Harden access with Tailscale operation permissions #684 appears as a branch bullet.
  • October 5 gains [ai][docs] devlog register format and PR numbers; 0.5.2 backlog cleanup #677's devlog and backlog work.
  • The five {dd/lidar/span-selection} bullets on October 5 now end in ([ai][go][docs] select the span and near-edge percentiles, balanced timing, D2 corpus refresh, and #676's records #678), and the tag is gone.
• Backlog
  • [ai][go][js][docs] run statistics and track quality columns: store what the tracker counts #690 and [ai][go][docs] lidarbench: compare distinct confirmed tracks as workload identity #692 removed their items when they merged. Remediation Phases 1, 2 and 4 and the perf track-count identity are now Complete entries.
  • [ai][go][docs] select the span and near-edge percentiles, balanced timing, D2 corpus refresh, and #676's records #678, [ai][go][docs] scene headway: clip encounters crossing the scene window (R4) #686 and [ai][go][docs] held-out scoring v2: pin reference content, gate unmatched references (R6) #688 left finished work inline in their parent items, under branch names. That work moves to Complete, and each parent keeps only what remains.
  • [ai][go] api: read an overflowing long-poll version as 0, not MaxUint64 #682 completes the Tailscale long-poll item.
  • [ai][cfg][docs] perf: recapture the mac baselines after #613 moved the tuning fingerprint #680 completes the mac half of the perf-baseline item. The CI half stays as "Capture ci perf baselines".
  • [ai][go][docs] replayeval frame timing: A2 moves the frame 2-7% at p99 where its update is 9-21x #689's frame timing is recorded beside the solid-body item it informs.
• Docs: the sprint review's R4 and R6 status lines and the PCAP read-in-place report cite [ai][go][docs] scene headway: clip encounters crossing the scene window (R4) #686, [ai][go][docs] held-out scoring v2: pin reference content, gate unmatched references (R6) #688 and [ai][cfg][docs] perf: recapture the mac baselines after #613 moved the tuning fingerprint #680 instead of branch names.

The branch was rebased onto main. The four commits from #677 that it carried were already on main through #677's squash, so the rebase dropped them.
