Session 😺🤖 2026-07-31 (job 3d51bfb5), 07:40 → ~08:45 EDT — the session-framework improvements session: three roadmap artifacts shipped to the review gate in about an hour, all by one Opus sibling while the lead stayed thin. #91 retargeted from sub-30s to sub-10-second session startup with a measured design published; #146 (durable todo list) and #147 (concurrent sessions) filed as new requirements under goal #73. The headline measurement: the init's entire network surface is ~4 seconds cold — ~99% of session-start latency is model round-trips, which reframed #91 from an API problem into an orchestration problem. Provenance note: this session ended mid-checkpoint and its draft was lost with the deleted job; the entry was recomposed from the session scratchpad and posted during session 2's wrapup.
#91 retargeted to sub-10s — title + body reworked around a measured Data Requirement, a 3-tier Design published to the site (design doc, deploy green), board Backlog → Design, decisions D1–D7 opened.
#146 durable todo list posted as obotclaw — one permanent list per goal and overall, updated not rewritten; sub-issue of goal #73, Requirement Gathering, 2026q3.
#147 concurrent sessions posted as obotclaw — autonomous runs alongside @jwildfire's and each other; sub-issue of goal #73, Requirement Gathering, 2026q3. Concurrency had no covering issue before this.
The init critical path, measured (input to #91's design): local hand-off reads 38ms · gh searches 0.9s/0.7s · project item-list 2.4s · session-hub sweep 3.8s cold / 2ms warm — full network surface ~4s cold, so the sub-10s bar is won or lost in model orchestration, not API calls.
Lists-over-prose preference captured to memory mid-checkpoint — bulleted lists in all agent output (diary sections, drafts, chat) unless a technical deep dive is asked for; this entry and its sibling are the first written under it.
Overnight, before the session: the roadmap-audit routine posted its 2026-07-31 pass (29 findings, 0 high, commit e1db0d5).
Sibling heartbeat timestamps drift — 👯🤖 session-improvements logged 08:56–09:13 lines while wall-clock was ~08:21: timestamps were modeled, not shelled. Fix direction (mandate $(date +%H:%M) in the append command) validated at briefing level in session 2; skill-level fix tracked on oa#57 (heartbeat hardening).
21 review decisions opened in one session (7 each on #91/#146/#147) — descriptive: the review-gate queue grows faster than it drains; see the 🙋 list.
Next session: loose ends
