Pure derive_pr_labels (foundation/policy/pr_labels.py) maps a PR's shape
to a stable org-structure label set: to master/to slave (is_root_pr
discriminator), root, MegaTask, and the owning layer (main-pm /
cell/{team} / subtask/{team}). Mirrors batch.py: object|None inputs,
enum-or-string normalization, no DB/I/O. Full slave-targeting semantics
(base_branch vs default_branch) land with the slave/master wiring (W-H);
YAGNI now.
GitService._apply_pr_labels posts the result to the GitHub labels API
best-effort (create-before-add, swallow 422/409, never raises) so a label
failure can never block PR creation. Wired at all three PR-opening sites:
create_pr (gateway path), create_pull_request (REST/task path), and
_push_and_open_conventions_pr (static chore label). Existing PR tests
mock _apply_pr_labels so they never hit the real labels API.
