- **fixed** — Fix crash during mass-ulw, DAG, and task work caused by pi-tui barrel being accessed before it was loaded by sharing warm-up state across bundle copies via globalThis symbols
- **fixed** — Prevent task bundle status widget timer from killing sessions by containing render faults to log once and skip instead of propagating errors
- **fixed** — Long sessions no longer stop compacting after ten successful compactions
- **fixed** — Todo snapshots no longer recursively retain full history, preventing KB to MB growth that refilled context after compaction
- **fixed** — Manual /compact command no longer aborts an in-flight continuation when there is nothing to summarize
- **changed** — Update @anthropic-ai/sdk pin to satisfy claude-agent-sdk's >=0.93.0 peer range
- **added** — Add artifact-level regression tests that inspect built bundles to prevent minification from silently stranding lazy barrels

##### OmO 5.0.0-beta.21 — hotfix

**If beta.20 killed your sessions, this is the release you want.**

###### The crash that killed sessions (beta.20) — fixed
`Error: The @earendil-works/pi-tui barrel was accessed before it was loaded` terminating the whole OmO process during mass-ulw / DAG / task work (#7339, #7340, #7351). Root cause: `omo-task.js` ships as an independent bundle with its own private copy of the lazy pi-tui state; the compose-level warm-up only warmed `omo.js`'s copy, the minifier collapsed the cold accessor into an unconditional throw, and the status-widget timer detonated it outside any try/catch.

The fix (#7354) is three layers deep:
- **Shared warm-up state across bundle copies** — both lazy boundaries (pi-tui and the senpi engine barrel) keep their memoized state on `globalThis` under process-wide symbols, so warming any copy satisfies every copy.
- **The task bundle warms its own copy at registration** — keeping its dynamic import alive through minification.
- **Render-fault containment** — task/DAG status widgets render from bare timers; a faulting frame now logs once and skips instead of killing your session. Ever again.
- Plus artifact-level regression tests that inspect the *built bundles* so minification can never silently strand a lazy barrel again.

###### Compaction reliability (the beta.19 complaints) — Senpi 2026.8.26 (#1124)
- Long sessions no longer stop compacting after ten successful compactions (the absolute cap is telemetry-only now; the failure circuit breaker still guards runaways).
- Todo snapshots no longer recursively retain full history (KB -> MB growth that refilled context right after compaction).
- A manual `/compact` with nothing to summarize no longer aborts an in-flight continuation.

###### Install hygiene (#1125)
- `bun i -g omo-ai@beta` no longer warns `incorrect peer dependency "@anthropic-ai/sdk@0.91.1"` — the SDK pin now satisfies claude-agent-sdk's `>=0.93.0` peer range (audited symbol-by-symbol, additive-only).

###### Credits
Community diagnosis nailed this one: @sanguneo (#7350), @NetVar1337 (#7341), @amsminn (#7352) — all three independently identified the bundle-copy split; their approaches are co-authored into the fix commits. Compaction fixes by @haamsuk-collab (#1124).

Install: `npm i -g omo-ai@beta`
