2026-04-25 — session 1

Single Claude Code session. ~30 minutes wall-clock. One human, one agent.

What was changed

Doctrine update

Standing rule on session lifecycle was upgraded from v1.0 to v1.1.

v1.0 (2026-04-25 earlier): agent must end a turn with Session disposable — safe to kill. Reason: <why>. when no further attention needed.
v1.1 (2026-04-25 same day): two-step protocol. Before signaling disposable, agent must scan the session for carry-forward value (architecture decisions, doctrine changes, infra completions, surprising findings, deprecations, project state, user feedback) and write to memory hub. Then declare Sedimented: <memo IDs> or Sedimented: nothing — routine session, no carry-forward value. THEN emit the disposable signal.

Rationale: disposable-without-sediment leaks the session’s learning. The two-step plugs the leak. Bar is auditable — the user can spot-check whether the agent applied the bar honestly.

Hub memo: mem_ef3b05ed4d8c (v2). Local mirror: three files synced.

Tool exploration

Computer Use (mac-use-mcp) was deployed to navigate Omi’s web dashboard for a historical data export. Two notable failures:

Mis-click on Omi sidebar (target was bottom-of-sidebar profile menu; landed on Discord invite link above it). Page navigated to discord.com/invite/....
Mis-click on /settings mobile-splash overlay (target was “Continue to web anyway” link; landed on the App Store CTA above it because hit-region extended further than visible bounds).

Both failures: 100% from coordinate guessing in a non-Accessibility-exposed React app (UI tree returned only Chrome chrome, not Omi DOM). Lesson logged: when AX tree is empty, prefer URL-based navigation over coordinate clicks; resize window to trigger the desktop layout instead of fighting the mobile splash.

Pipeline initialization

This repo was created as the canonical receipts archive. Sibling pipelines (X artifact stream, weekly digest) bootstrapped same session.

Distribution channel surprise

Discovered during pipeline setup that the assumed primary X account is permanently suspended (read-only mode, “you won’t be able to create new accounts”). Pivoted to a secondary live X account (@MachengShen) for the artifact stream.
