Integration Gate

Use this gate to promote completed task facts into canonical project memory.

Requirements

Run in an exclusively owned integration worktree.
Hold the repository integration lock.
For a single completed Feature, create the Integration worktree from that Feature commit so its task-owned records are already inside the Integration task's recorded base. Verify the target default branch is an ancestor or reconcile it explicitly before canonical edits; starting from the older default branch and then introducing another task's record will correctly fail the drift gate.
Verify the task commits being integrated are present.
Review source task records, task-prefixed supporting records, promotion candidates, and semantic conflicts in read-only mode.
Write integration notes only to the integration task's own task record or {task_id}__<slug>.md supporting records.
Ask before changing architecture direction, product behavior, or accepted decisions.
Record source task or merge commits under Integrated Through in current-state.md.

Do not resolve meaningful document conflicts with ours, theirs, or union merge rules.
