-# 045 — Timeline/log ordering by params other than `ottyl_ts`, with drop/fallback toggle
-
-## Summary
-
-Log lines are currently rendered in whatever order the backend returns
-them, which is ingest order (`sequence`, monotonically increasing per
-`src/ingest.rs`) surfaced via `webapp/src/components/LogPreview.tsx:258-261`
-(`log.sequence`/`log.timestamp_ms`). `webapp/src/components/LogTimeline.tsx`
-only draws pre-bucketed histogram bars from `fetchTimeline`
-(`webapp/src/lib/api.ts:257` → `GET /api/timeline`, `src/api.rs:249
-get_timeline`) and has no per-line sort control at all. There is no way to
-order by a declared param, and no defined behavior for lines missing
-whatever param is chosen for ordering.
-
-## Scope
-
-- Default ordering stays by `ottyl_ts` (see ticket 044 for the rename).
-- Add the ability to choose a different declared param as the sort key for
-  the timeline/log list (backend: extend the timeline/log query path in
-  `src/api.rs`/`src/engine.rs` to accept a sort-by param; frontend: expose
-  the choice near the timeline/log controls, likely in
-  `LogTimeline.tsx`/`LogPreview.tsx` or their shared settings).
-- Add an explicit toggle controlling how lines lacking the chosen sort
-  param are handled: (a) fall back to ordering those lines by `ottyl_seq`,
-  or (b) drop them from view entirely. Persist this toggle alongside other
-  view settings.
-- Ensure the toggle and sort-by selection are scoped sensibly (e.g. per
-  timeline/session) rather than silently global if that would surprise
-  users switching between dashboards.
-
-## Acceptance criteria
-
-- User can pick any declared param as the ordering key for the
-  timeline/log view, in addition to the `ottyl_ts` default.
-- With the fallback toggle on, lines missing the sort param appear
-  ordered by `ottyl_seq` relative to each other; with it off, those lines
-  are excluded from the view — both verified with a seeded fixture mixing
-  lines with and without the param.
-- Existing default (`ottyl_ts`-ordered) behavior is unchanged when no
-  alternate sort param is selected.
-
-## Depends on
-
-044 (reserved param naming — this ticket's default sort key and fallback
-key should use the renamed `ottyl_ts`/`ottyl_seq`).
