Two new per-viewer flags on activities, mirroring the heart/done shape:
- ARCHIVE: any viewer (incl. the owner) can archive a row. Out of
sight by default but the permalink still resolves. For owners,
archive also filters the row out of their /<bruker>/liste public
page — "I'm done sharing this."
- HIDE: only non-owners. "This doesn't appeal to me." Endpoint
returns 400 cannot_hide_own when the owner tries it (they should
delete or archive instead).
Both default-filtered from GET /api/activities. Opt-in via query
params with three modes each: exclude (default), include (1), only.
?archived=1&hidden=1 includes both; ?archived=only shows just the
archive. The list endpoint composes the SQL filters per-viewer
(anonymous viewers have no rows in either table → no-ops).
Schema: two new tables user_archived_activities and
user_hidden_activities, both composite-PK on (user_id, activity_id),
cascade on both refs. Same shape as the existing engagement tables.
Types: viewer_archived + viewer_hidden on every Activity variant.
viewer_hidden on private is always false (the endpoint refuses);
docstring on the type explains why.
Bulk lookups extended so the list endpoint stays at constant queries.
Single-row paths get per-row viewerArchived/viewerHidden helpers.
fetchRowForViewer keeps preserving the viewer's custom sort_position
on toggles.
UI: two new buttons in ActivityRow's action row — "📦 Arkiver" /
"📦 Arkivert" (everyone) and "🙈 Gjem" / "🙈 Skjult" (non-owners
only). Two new checkboxes near the search field on /hjem: "📦 Vis
arkivert" and "🙈 Vis skjult". Toggling either re-fetches from the
server because the filtering is server-side. When an archive/hide
flips the row out of the current view, Home.svelte triggers a
refetch so the row disappears in real time.
Public-list endpoint (/api/users/:bruker/list) also filters out the
owner's own archived rows — consistent with "archive means filed
away from active view."
Tests: 3 new in engagement.test.ts — viewer archives + per-viewer
isolation, owner's archive filters their public list, hide refuses
on own row + ?hidden=only path. Suite goes 102 → 105.
