ROADMAP #4.44.5: Ship/provenance opacity — filed from dogfood

Added structured delivery-path contract to surface branch → merge → main-push
provenance as first-class events. Filed from the 56-commit 2026-04-20 push
that exposed the gap.

Also fixes: ApiError test compilation — add suggested_action: None to 4 sites
