Session 🦾🤖 2026-08-01 140-design (job 4a6f66b8), 08:00 → ~09:40 EDT — the fourth A1 autonomous run: init selected the carried #140 design increment and delegated it whole to one Opus sibling, which shipped the design to the review gate 13 minutes after spawn. Also the first run to share the day with a live parallel session — @jwildfire's interactive session 2 started at 08:13 (the #91 speed test) and confirmed the in-flight increment rather than duplicating it, so #147's concurrent-sessions question is no longer hypothetical. Headline: the design pass surfaced a new guardrail hole — obot-merge trusts the invoking worktree's policy.json, making the carve-out gate removable by the very PR it governs — now tracked as oa#75.

Work completed
#140 Design shipped to the review gate (goal #73; 👯🤖 140-design, Opus 5): design doc published (hub main c646fb4, deploy green, page 200) covering Gate A (carve-out enforcement — oa#65's fix via a repo-qualified v3 schema + changed-files check forcing the attested lane), Gate B (the new authority-ref hole), and truthful --check (Ideas #141 — separate policy and mergeability verdicts). D1–D8 queued for review; nothing implemented, no obot.agent code touched.
Board and body synced: #140 stage Requirement Gathering → Design; body's Design section points at the doc and its stale Migration paragraph was corrected; obotclaw comment on #140; reply in Ideas #141.
Two measured facts now constraining the implementation: gh pr view --json files truncates at 100 files (paginated REST returns all 318 on the probe PR), and mergeable/mergeStateStatus come back UNKNOWN on the first query — the check needs a re-poll.
Risk filed: oa#75 (Gate B) with three mitigation options, recommending the fix ride the #140 implementation PR together with Gate A.
Traceability comments: on oa#65 (design published, measured facts, expected single-PR shape) and on oa#57 (briefing-contract scope add — see blockers).
Init hygiene: hand-off read from all three sources (converged), delta agent clean (no overnight changes; sv#122 confirmed merged 07-31; Ideas #135/#137 closed as promoted; all 7 open PRs untouched since 07-29), ideas inbox empty on both lanes.
PRs / issues touched
Opened: oa#75 — Gate B authority-ref hole (risk + mitigations).
Advanced: #140 (→ Design, design published) · oa#65 and oa#57 (comments) · Ideas #141 (reply; stays open until #140's design is approved).
Merged / closed: none — design-only increment.
Blockers / risks
Gate B — obot-merge resolves policy from the invoking worktree, so the carve-out gate is removable by the PR it governs (third instance of the oa#60 family) → filed as oa#75 with a recommendation to land it inside the #140 implementation PR.
Finished siblings read as running — a sibling that closes out in the scratchpad but doesn't end its final message with a result: line never goes terminal in job state; this false-tripped the lead's 40-minute stall monitor and leaves the agents view showing a done sibling as active → scope added to oa#57 (one-line session-spawn briefing fix).
Transient: the auto-mode permission classifier was briefly unavailable mid-session (upstream model outage), delaying the lead's verification pass ~45 minutes — no action to take; context for the oa#74 classifier-lane family.
Next session: loose ends
#140 implementation — after D1–D8 review: one obot.agent PR closing oa#65 + oa#75 + Ideas #141 (D7 decides whether oa#37's CI gate folds in). (new)
Draft the #34 app-first plan rewrite — after demo review notes (goal #79). (carried)
