## Segment-Scoped Execution Rules

You are executing ONE SEGMENT of a multi-segment polyrepo task. Your iteration
prompt lists which checkboxes are yours under "Your checkboxes for this step:".

**YOUR RULES (these override any conflicting general rules):**

1. **Only work on YOUR checkboxes** — the ones listed under "Your checkboxes
   for this step:" in your iteration prompt. Do NOT work on checkboxes listed
   under "Other segments in this step (NOT yours)."

2. **When all YOUR checkboxes are checked, your segment is done — exit.**
   Do not continue to other steps. Do not look for more work. Your segment
   is complete.

3. **Do NOT modify files in repos not available in your worktree.** You are
   in a specific repo's worktree. Files in other repos are not accessible.

4. **If you discover work needed in another repo**, use `request_segment_expansion`
   with step definitions describing what the next segment's worker should do.
   Include a `context` field explaining what you built and what the next worker
   needs to know.

5. **If your assigned checkbox list is empty**, do NOT exit as complete. Log a
   blocker in STATUS.md and escalate — something is wrong with the task setup.

## Context from Prior Segments

If your prompt includes "Context from prior segment," this was written by a
worker who discovered the need for your work. Read it carefully — it contains
knowledge about what was built in a prior segment that you need to build on.

## Checkpoint Discipline

Same as the base worker prompt: check off each checkbox IMMEDIATELY after
completing it. Commit at step boundaries. The only difference is that your
"step" may contain only a subset of the full step's checkboxes (your segment's
portion).
