-# 053 — Move the log sort selector from Log Preview to the Timeline
-
-## Summary
-
-The "Sort by" control lives in the wrong component. It's currently
-rendered inside `LogPreview`'s own section header
-(`webapp/src/components/LogPreview.tsx:327-336`) as a `SortPicker`
-(`LogPreview.tsx:68-107`, a `<select>` plus an "Fall back to ottyl_seq"
-checkbox), with its `LogSortSettings` type and
-`loadLogSortSettings`/`saveLogSortSettings` persistence helpers
-(`LogPreview.tsx:37-66`, localStorage key `ottyl.logPreview.sort`) also
-defined there. `LogTimeline.tsx` has no sort-related prop at all
-(`LogTimeline.tsx:44-56`) — its header only has time-range preset buttons
-and a "Clear selection" link (`LogTimeline.tsx:118-149`).
-
-The actual sort state is owned one level up, duplicated identically in
-`App.tsx`'s two top-level render modes: `FullApp`
-(`App.tsx:389-394`) and `StandaloneLog` (`App.tsx:263-268`), both via
-`useState<LogSortSettings>(loadLogSortSettings)` plus a
-`handleSortSettingsChange` callback. Both currently pass
-`sortSettings`/`onSortSettingsChange` only to `LogPreview`
-(`App.tsx:361`, `App.tsx:527`), never to `LogTimeline`
-(`App.tsx:237-243`, `354-360`/`520-526`). The setting already drives
-`fetchLogs` (`App.tsx:319-326`, `464-471`, dependency at `App.tsx:347`,
-`494`), which forwards `sortBy`/`sortMissingFallback` to
-`GET /api/logs` via `fetchLogs` in `webapp/src/lib/api.ts:242-262`. The
-backend already fully supports this — `src/dto.rs:86-90`'s
-`sort_by`/`sort_missing_fallback` fields, validated and applied in
-`src/engine.rs:1223-1281` (400 if `sort_by` isn't a declared param,
-`engine.rs:1227`; missing-value fallback behavior at `engine.rs:1260-1281`).
-The timeline query/DTO backing `fetchTimeline`
-(`webapp/src/lib/api.ts:264-274`) has no `sort_by` field and doesn't need
-one — this is a frontend-only relocation of where the control lives, not
-a backend change.
-
-## Scope
-
-- Move `SortPicker` (and ideally the `LogSortSettings` type plus
-  `loadLogSortSettings`/`saveLogSortSettings`) out of `LogPreview.tsx`
-  into `LogTimeline.tsx`, rendering it in the Timeline's header
-  (`LogTimeline.tsx:118-149`) alongside the existing range controls.
-- Add `sortSettings`/`onSortSettingsChange` props to `LogTimeline`.
-- Update both `App.tsx` render sites (`FullApp` around line 237,
-  `StandaloneLog` around line 354/520) to pass `sortSettings`/
-  `onSortSettingsChange` to `LogTimeline` instead of `LogPreview`.
-- `LogPreview` keeps rendering the `logs` prop as already sorted by the
-  parent's `fetchLogs` call — remove its own `SortPicker` usage and the
-  now-unused sort-control markup from its header, but keep consuming
-  `sortSettings` if it still needs read access to it (e.g. for a
-  "sorted by X" label), or drop that too if not needed.
-- No backend changes — `sort_by`/`sort_missing_fallback` on
-  `GET /api/logs` are unaffected.
-
-## Acceptance criteria
-
-- The "Sort by" selector and "fall back to ottyl_seq" checkbox appear in
-  the Timeline component's header, not in Log Preview's.
-- Changing sort order from the Timeline's control changes the order of
-  entries shown in Log Preview (same behavior as today, just relocated).
-- The chosen sort setting still persists across reloads (localStorage key
-  can be renamed if it moves file, but must not silently reset to
-  default on the first load after this change — migrate or fall back
-  gracefully).
-- `make build` (webapp `tsc -b && vite build`) passes with no leftover
-  unused imports/types in `LogPreview.tsx`.
-
-## Depends on
-
-None.
