| 1 | //! One projection of durable saved sessions, shared by every surface that |
| 2 | //! browses them (#2934 / #4397). |
| 3 | //! |
| 4 | //! Before this module the TUI session picker and the Runtime API answered |
| 5 | //! "what sessions are there?" with two different shapes: the picker filtered, |
| 6 | //! sorted, and fuzzy-matched [`SessionMetadata`] in place, while |
| 7 | //! `GET /v1/sessions` returned an unfiltered, unsorted metadata dump with an |
| 8 | //! ad-hoc substring search. That divergence is exactly what the web dashboard |
| 9 | //! could not consume, and it is what made "the rail says one thing, the |
| 10 | //! dashboard says another" possible. |
| 11 | //! |
| 12 | //! Everything here is pure and offline: |
| 13 | //! |
| 14 | //! * no provider or network call — browsing and resuming must never talk to a |
| 15 | //! model, so a projection is computed from already-read metadata only; |
| 16 | //! * no session-file reads — [`SessionSummary`] is built from |
| 17 | //! [`SessionMetadata`], which the manager already extracts from a bounded |
| 18 | //! 64 KB prefix. A rail that re-read every transcript on every render would |
| 19 | //! be a per-keystroke I/O storm on a 50-session store. |
| 20 | //! |
| 21 | //! The consequence is deliberate and worth stating plainly: a summary's |
| 22 | //! `preview` is the session's own title, not its last message. Session |
| 23 | //! metadata does not record a last message, and inventing one by reading N |
| 24 | //! transcripts per frame would trade a truthful cheap row for an expensive |
| 25 | //! one. Full transcript preview stays where it already works — the session |
| 26 | //! picker, which reads one selected session and caches it. |
