Why

resolve_project_id let any 36-character UUID through unchecked, so a stale id in an agents projects definition read as "no issues". agi-ui's recorded Linear id (2a56fa44-…) no longer exists in the workspace, yet linear tasks --project 2a56fa44-… --json printed "count": 0 with exit 0. The AGI EXT Project panel would show an empty Issues tab instead of an error.

What

• Strict resolution (every explicit --project) now checks a UUID against list_team_projects. This is the same membership check resolve_auto_project_id already does for the cwd binding. A miss raises LookupError, which every strict caller already turns into Error: … and exit 1.
• Non-strict callers keep the pass-through and make no extra API call.
• CHANGELOG entry under Unreleased.

This is part of routing the Project panel's Linear reads through agents projects tickets in agents-cli. It is independent of #74.

Independent review by a non-author code-reviewer subagent. Verdict: APPROVED (non-blocking findings addressed).

• Every strict resolve_project_id caller handles LookupError. python3 -m unittest test_linear: 283 OK.
• Fixed in 0fbc352: an unreadable (empty) project list no longer reports a valid id as stale, and the message names archived projects.
• Re-run: 284 OK. A live stale id exits 1 with the message; the live AGI id lists.
