Remove the per-user oneliner watermark, which was previously used to
generate ETags for the `/api/oneliners` endpoint. The watermark was
intended to track the last successful oneliner write for each user.
The ETag generation has been refactored to use a deterministic FNV-1a
hash. This hash is computed over a sorted list of tuples containing
`(case_id, last_recording_at_ns, oneliner_mtime_ns)` for all visible
cases. This approach ensures that the ETag changes whenever any
listen-relevant file system modification occurs, such as a new
recording, oneliner regeneration, soft-delete, undo, or
upload-auto-reopen. This new method is more robust and avoids the
complexity of managing per-user state.
The `OnelinerWatermark` type alias and its associated logic have been
removed from `AppState` and the relevant modules (`transcribe::worker`,
`transcribe::recovery`, `routes::oneliners`, `main`). New integration
tests have been added to verify that various delete operations (single
delete, undo delete, bulk delete) correctly trigger an ETag update,
ensuring cache invalidation.
Introduce `last_recording_at` to `OnelinerEntry` and use it as the
primary sort key for cases. This ensures that cases with recent
dictation activity are prioritized, even if their initial creation date
is older.
The logic for determining a case's activity has been updated to consider
the most recent `.m4a` file's modification time (`last_recording_at`),
falling back to `updated_at` or `created_at` if necessary.
This change also refactors the timestamp formatting and handling within
the web interface to correctly display and sort cases based on their
actual last activity time, improving user experience and data relevance.
The `now_rfc3339` function is updated to strip sub-second precision for
consistent filename generation.
This commit introduces a new API endpoint `/api/oneliners` that allows
authenticated users to retrieve a list of their recent oneliners.
The endpoint supports conditional GET requests using the `ETag` header
for efficient caching. It also allows specifying a time window for the
oneliners via the `hours` query parameter, with sensible defaults and
clamping.
The implementation includes:
- A new route handler `handle_oneliners`.
- A new type `OnelinerWatermark` for tracking user-specific timestamps.
- Logic for scanning user data directories, filtering by time, and
handling deleted cases.
- Test cases to cover various scenarios, including caching, time
windowing, and edge cases.
