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) 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

No --migrate required.
