- Review 614b6263 (codex, P2): `opencode session delete` removes the child
sessions with their parent, but their 1.x rows stayed and the parent's
residual was empty. The child sessions (session_v2 and a 1.x session
table, any depth) are taken before the delete; the 1.x tables (message,
part, todo, session_share, session) are cleaned for all of them, and the
residual also reports a child still on record (a failed delete).
- The in-use check counted any process holding the shared opencode.db; the
per-user 2.x background service (`serve --service`) holds it for every
session, so every opencode purge was refused while it ran (it does on
this Mac). It no longer counts; any other holder and a command line
naming the session still do.
- The data dir follows the caller's XDG_DATA_HOME when ctx is the caller's
own home (else <home>/.local/share), for debug paths, the fallback and the
residual scan (review 614b6263 / f4cedbae N4).
- resident_children = ('opencode',): the --standalone server stays the TUI's
idle child; what runs under it still counts (review 1abe0a90).
- Tests: child sessions on a migrated database, a failed delete, the service
holder, XDG, resident children, drift C pinning the parent over a newer
child session (review f4cedbae N2), and the real-binary test no longer
depends on PATH (N1).
