Operator-flagged 2026-06-01: clicking a Provenance post title from the
view modal opens the post in the posts feed scoped to that artist
(`/posts?post_id=N&artist_id=A`), but the older/newer infinite-scroll
loaded UNFILTERED global posts instead of staying in the artist's
stream. Root cause: the posts store's loadAround/loadOlder/loadNewer
sent only `{around, cursor, direction}` — never the `artist_id` /
`platform` filters. Backend `/api/posts` accepts them on every path
(post_feed_service.scroll filters via `Source.artist_id`); the
frontend just wasn't passing them.
Fix:
- `posts.js` `loadAround(postId, filters)` now takes the filter
snapshot and stores it. `_aroundParams(extra)` mixes the active
filters into around/cursor calls.
- `PostsView.vue` `loadAroundAndAnchor` passes `artist_id` +
`platform` from the route query.
Provenance "View post" deep-links to /posts?post_id=X, which now opens the
feed centered on that post with infinite load in BOTH directions.
Backend: PostFeedService.scroll gains a direction (older|newer); new
around(post_id) returns a window of newer + the post + older with a cursor
for each end. /api/posts accepts ?around= and ?direction=. + API tests.
Frontend: posts store gains loadAround/loadOlder/loadNewer (older appends,
newer prepends) with per-end cursors; PostsView's anchored mode scrolls to
the post, observes top + bottom sentinels, and preserves scroll position on
upward prepend so the page doesn't jump. Normal feed mode unchanged.
Closes the remaining half of the post-navigation work.

New composables/useAsyncAction.js owns the loading/error/try-finally
lifecycle. Migrated 11 stores: credentials, downloads, sources, posts
(error=raw) + ml, artistDirectory, tagDirectory, showcase, suggestions,
seriesReader, modal (error=message). The errorAs option preserves each
store's existing error shape so store.error keeps the same type for
components (~50 consumption sites unchanged). Stores whose catch also
reset data (suggestions/seriesReader/modal) clear it upfront instead.
Deliberately NOT migrated (special control flow, would change behavior):
artist (conditional 404 catch + dual loading states), migration (rethrows),
gallery (inflight-id stale-response guard), and the Shape-B no-catch /
loaded-guard / keyed-cache stores.
Net -77 lines.
