Research direction

Start with packages/core/src/session/store.ts around line 108 and compare the project-scoped filter with packages/opencode/src/session/session.ts around lines 970-976. Check how SessionStore.list handles a root subpath and reproduce the query against rows where path IS NULL. Done means correctly attributed root sessions appear in the project list without changing all-project behavior.

Description

Description

Sessions with path = NULL are missing from project session lists after the v1→v2 upgrade, even though their project_id is correct.

v1 began with no path column; 20260428004200_add_session_path added it (default NULL), and v1's inserts still left it NULL for root-level sessions for a while (in our DB: a clean NULL window 2026-04-03→05-05, with every later session writing ''). The v1→v2 importer copies path verbatim, so these rows arrive in session_v2 with path IS NULL. The project-scoped picker sends {project, subpath: ''} and SessionStore.list filters with an exact eq(SessionTable.path, input.subpath) (packages/core/src/session/store.ts:108) — in SQL, NULL = '' is not true, so the rows are excluded. The projector only rewrites the path of the session that triggered a Resolved event; historical rows are never backfilled.

Scope in our DB (opencode 2.0.14, upgraded from 1.18.x): 90 sessions — 88 in one git repo (87 top-level, mostly user-initiated forks, ~1,300 messages total) + 2 in a second repo. All have directory = project.worktree, so the correct value is ''. They are only reachable via "all projects" scope / global search.

This is a different defect from #50980 (where the row is absent from session_v2 entirely) and from the project_id='global' family (#50551, #50800, #50999): here the project attribution is right, only path is null.

Plugins

None relevant (server-side data/filter behavior).

OpenCode version

2.0.14 (affected, by source comparison: 2.0.14–2.0.16; not fixed on latest tag)

Steps to reproduce
  1. In opencode v1, create sessions in a git repo root during the window where v1 didn't write path (around the 20260428004200_add_session_path change — e.g. after the path column exists but before v1 started writing '').
  2. Upgrade to v2.0.14–2.0.16 and open that repo. The import copies path = NULL into session_v2.
  3. List sessions in the project: the NULL-path sessions don't appear, though "all projects" scope shows them.

Check your own DB:

SELECT project_id, directory, COUNT(*) FROM session_v2 WHERE path IS NULL GROUP BY 1, 2;
Expected Behavior

Sessions whose directory equals the project worktree should be listed at subpath = '', i.e. NULL should be treated as the empty path (the dev branch already adds this: and(isNull(path), eq(directory, …)) at packages/opencode/src/session/session.ts:970-976).
