Problem

The os-sdlc-subagent-stop hook fails with exit 3 when it runs from a git worktree. It works from the main checkout.

Observed

decision-model implementation 6 (#16), worktree .claude/worktrees/ticket-16 (its .sdlc/pipeline.db is a link). The behavior-verifier (dispatch 67) got:

os-sdlc-subagent-stop: harness error: Sequel::Error: No database associated with Sequel::Model: have you called Sequel.connect or Sequel::Model.db= ?

I sent the same saved handoff JSON on stdin from the main checkout directory. It succeeded.
A later programmer dispatch saw the same error once. It succeeded when re-run from the worktree directory.

So the failure seems to depend on the working directory. Cause not confirmed.

Acceptance criteria

Given a session in a git worktree with a linked .sdlc/pipeline.db, when a subagent stops, then os-sdlc-subagent-stop connects to the database and exits 0.
Given the database cannot be opened, when the hook runs, then it reports the path it tried, not only the Sequel error.
