The summary_actions table records the maintainer's act on a summary, the
column that makes the Stage-0 headline test ("acts on >=1 summary") queryable
(ui-spec.md §5, ADR-011). This is the gate lanes B/C build on.
- Migration 002: summary_actions (id, user_id, video_id TEXT, action, acted_at)
with a CHECK on action IN ('watched','skipped','saved') and a UNIQUE
(user_id, video_id, action). Per-user isolation: every row carries user_id.
- New actions.go: SetAction (idempotent, atomic watched<->skipped mutual
exclusion in one tx; saved independent), ClearAction, ActionsFor for the list
view, plus Go-side action validation.
- reads.go: additive SummaryRow.Actions, populated by composing ActionsFor
(Go-side, not a SQL join — summaries.video_id is UUID, actions.video_id TEXT).
- embedded-postgres tests: set/clear, mutual exclusion, saved coexistence,
idempotency, invalid rejection, user scoping, read-view surfacing.

ListSummaries (recent-first, user-scoped, limit) and GetSummaryByVideo
LEFT JOIN videos for title/url/published_at, null-safe when no videos
row exists. Channel mirrors provider for now — channel_title lives on
the not-yet-migrated subscriptions table (data-model.md). New file so it
does not collide with Worker F's concurrent edits to store.go.
