desktop: all projects show no sessions — session list fails with 'Path is not absolute: .' from a legacy session row (v1.18.31, Windows)

Summary

On Windows, OpenCode Desktop (stable 1.18.31) shows no sessions under any project ("아직 아무것도 없습니다 / 세션을 생성하시 시작하세요"). The session list fails to load because at least one legacy session row has a non-absolute directory value ("." or "/"), which trips a path assertion:

Error: Path is not absolute: .

Since the list query (V2Session.list) validates/decodes every row, one malformed row breaks the entire session list, so every project appears empty — even though 433 sessions exist in the DB.

Environment

• opencode desktop: 1.18.31.0 (%LOCALAPPDATA%\Programs\OpenCode\OpenCode.exe)
• opencode CLI: 1.18.31
• OS: Windows 11 Enterprise, build 26100 (AMD64)
• DB: %USERPROFILE%\.local\share\opencode\opencode-desktop.db (same rows also exist in opencode.db)

Steps to reproduce

1. Have a session row whose directory is not an absolute path (e.g. "." or "/") — from legacy sessions (version 1.2.x, ACP/Codex).
2. Launch the desktop app and open any project.
3. The project's session list is empty; the server log shows the error below. The same happens for all projects.

Expected behavior

Sessions list normally. A single malformed/legacy row should not fail the entire list.

Actual behavior

GET /api/session (session list) fails; the UI shows no sessions for every project.

Server log (%USERPROFILE%\.local\share\opencode\log\opencode.log):

level=ERROR message=failed error="EffectDrizzleQueryError: Failed query: select \"id\", \"project_id\", \"workspace_id\", \"parent_id\", \"slug\", \"directory\", \"path\", \"title\", \"version\", ... from \"session\" order by \"session\".\"time_created\" desc, \"session\".\"id\" desc limit ?
params: 5000 (cause: Cause([Fail(Error: Path is not absolute: .)]))"
    at V2Session.list (file:///.../app.asar/out/main/chunks/node-Cc1MVJxA.js:733450:40)
    ...
  [cause]: Error: Cause([Fail(Error: Path is not absolute: .)])

DB evidence

SELECT id, directory, path, title, project_id, version FROM session
WHERE directory IN ('.', '/', '') OR directory IS NULL;

Result (present in both opencode-desktop.db and opencode.db):

ses_3905a52d4ffewsWT8Upaxth7fs  directory='.'  title='ACP Session d63e4d24-59e0-455d-92d1-46eb7fec80a1'  project_id='global'  version='1.2.4'
ses_3a1418943ffeufvbTzooPhgAAb  directory='/'  title='현재 codex 연결 여부 확인 대화'                         project_id='global'  version='1.2.3'

Total sessions: 433; non-absolute directory: 2.

Root cause (analysis)

A path helper asserts that a location is absolute. The session list validates each row's location, so a single legacy row with directory="." throws and the whole list request fails, leaving every project's session list empty. This looks like the same "Path is not absolute" assertion family seen in the workspace=global reports, but here the offending value is a stored session directory ("."), it affects stable 1.18.31 on Windows, and the failure is data-driven rather than workspace-driven.

Impact

All projects show no sessions in the desktop UI even though sessions exist in the DB. Data is intact.

Workaround

With the app closed, normalize/repoint the offending rows:

UPDATE session
SET directory = 'C:/Users/<user>'
WHERE directory IN ('.', '/', '') OR directory IS NULL;

After this, the session list renders again.

Suggested fix

• Skip or normalize rows with a non-absolute directory instead of failing the whole list.
• Add a migration to repair legacy rows where directory is in ('', '.', '/').
• Consider hardening the path normalization used by Session.list.
