Fixes the inconsistency where switching the memo list to update_time
left the activity heatmap aggregating by created_time. The heatmap
now follows the same time basis as the list it sits next to.
Backend
- UserStats gains memo_updated_timestamps (additive proto field, tag 8).
- GetUserStats and ListAllUserStats populate it alongside the existing
memo_created_timestamps. No DB migration; memo.updated_ts already
exists on every row.
Frontend
- useFilteredMemoStats reads timeBasis from ViewContext and selects
the matching timestamp source.
- StatisticsView and MonthNavigator forward timeBasis through to
MonthCalendar / YearCalendar so tooltip text matches the basis
("X memos in DATE" vs "X memos updated on DATE").
- Falls back to memoCreatedTimestamps when an old server returns an
empty memoUpdatedTimestamps array (detected by length divergence,
since protobuf-es deserializes missing repeated fields as []).
Tests
- Backend: TestGetUserStats_MemoUpdatedTimestamps verifies the field
is populated and reflects post-creation updates.
- Frontend: filtered-memo-stats covers create/update source switching
and the old-server fallback path; activity-calendar-tooltip covers
basis-aware label selection.
Spec and implementation plan committed under docs/superpowers/.
Gate auto-save on initialization to prevent empty content from overwriting
cached drafts on remount. Flush drafts synchronously on visibilitychange/
pagehide so Chromium tab suspension cannot drop pending debounced saves.
Restore cached draft over saved memo content when they differ (inline editing).
- simplify ActivityCalendar state handling and shared max-count utilities
- remove calendar ring styling and darken the default dark theme primary colors
- tighten the audio recorder panel layout and action sizing
Keep the unpublished image-sharing flow scoped to memo detail pages.
- add a dedicated share-image preview and export pipeline
- measure the rendered memo card so preview and exported image stay aligned
- move the entry point into the detail sidebar and drawer only
- split attachment page states and primitives into focused components
- unify card and list item presentation across media, audio, documents, and unused uploads
- move attachment paging and cleanup flows onto shared query and view-model hooks
