# v0.6.17

> 2026-09-12

Devin CLI session memory, on-demand SQLite page reads, and task/session binding fixes.

## Enhancements

### Devin CLI session adapter

`trellis mem` reads Cognition Devin CLI sessions from `~/.local/share/devin/cli/sessions.db` (WAL SQLite) through the existing zero-dependency parser. This is not `trellis init --devin` (Desktop/Cascade) and not Factory Droid. (#614)

* `--platform devin` on `list` / `search` / `extract` / `context` / `projects`
* OpenCode, ZCode, and Devin share `packages/core/src/mem/internal/sqlite-adapter.ts` and `packages/core/src/mem/platforms.ts`
* Devin forests require `main_chain_id`; a missing tip is `devin-main-chain-missing` (no `max(node_id)` fallback)
* `CREATE TABLE` `--` line comments are stripped so `parent_node_id` and `chat_message` parse on live `sessions.db` files

## Bug Fixes

### Lazy SQLite main-page reads

The zero-dependency SQLite reader in `packages/core/src/mem/internal/sqlite-readonly.ts` loads main-file pages on demand instead of reading the whole database into memory. (#596)

### Pi headless subagent prompts

Pi `trellis_subagent` forwards ask-policy prompts to the parent session. The serving heartbeat sets `PI_SUBAGENT_PARENT_SESSION` (not a stale `PI_SESSION_ID`), sets `PI_SUBAGENT_CHILD=1`, and drops inherited `PI_SESSION_ID` so the child mints its own. (#611)

### Active-task session fallback

Resolving an active task from a missing session id no longer falls back to the only session in the project. That fallback is explicit opt-in, so one session cannot bind another session's task. (#608)

### Archive child unlink restore

If `task.py archive` fails after unlinking some children, it restores each child's `parent` link from a snapshot taken before the clear. A duplicated `children` entry is snapshotted once so a second visit cannot restore `parent: null`. (#613)

## Upgrade

```bash theme={null}
npm install -g @mindfoldhq/trellis@latest
trellis update
```

No `--migrate` required.
