# Read Before Coding

Before editing code, verify that the implementation plan passed both the Concurrent Task Gate and Planning Gate. Confirm the task ID, branch, worktree, owner, and active task record still match.

If the plan is stale, ownership changed, or new peer scope affects the plan, return to `read-before-planning.md`. Keep every later file and Git operation rooted in the owned worktree.

Read the source files directly related to the target modules. Record feature progress, discovered constraints, verification, and promotion candidates in `.project-docs/30-worklog/tasks/{task_id}.md`; leave canonical project memory to Integration Gate.
