Repo/Adopt mode (POST /api/lanes/ensure) treated lanes.cwd as globally
unique, so adopting a path already driven by one CLI silently ignored a
different tool choice. Uniqueness moves to the composite (cwd, tool):
one directory can now back a claude lane and a codex lane side by side.
- server/db.js: drop the column-level UNIQUE on cwd, migrate existing
DBs via table rebuild, add idx_lanes_cwd_tool.
- resolveLaneByCwd gains an optional tool filter; hook ingestion always
pins to "claude" since Codex has no hook mechanism here, so a hook
event never touches a codex lane sharing the path.
- POST /ensure resolves the existing owner by (cwd, tool) instead of
cwd alone, so a different tool creates a sibling lane.
- LaneConsolePane's cwd-only lane lookups now also match tool, so a
shared cwd doesn't attach a run to the wrong sibling lane.
Worktree mode is unaffected (already allocates a unique directory per
lane). docs/LANES.md and CLAUDE.md updated to describe the new
composite uniqueness.
