History was a date-grouped list you scrolled. Finding a session from last
week meant eyeballing every row. This adds a search field to the existing
filter rail, next to the host picker.
Search runs on the daemon, not the client. The daemon already holds every
persisted agent in memory, so it ranks the whole history and the client
never has to warn that it only looked at the pages it had loaded.
A searched response is one ranked page with no cursor. The global top K is
always contained in the union of each host's own top K, so merging per-host
pages and slicing back to the limit is the exact global answer — no k-way
merge, and no offset into a ranking that is recomputed per request, which
would duplicate and skip rows as history changes underneath it. Past result
200 of a relevance order the answer is a narrower query, so the footer says
that instead of offering a "Load more" that cannot deliver.
Matching is the app's existing picker matcher, moved to the protocol package
so app and daemon share one implementation instead of drifting into two
"why didn't this show up?" rule sets. Typo tolerance is opt-in, so the
comboboxes keep exact narrowing; the budget is per token, and four-character
tokens get transpositions only, because at that length a free substitution
turns "main" into "mail", "maid" and "rain".
Ranked rows carry the spans they matched on, so results can mark them. The
subsequence and typo tiers match characters the eye would never find
unaided, and an unexplained row reads as a bug. The ranker computes the
spans anyway; sending them keeps the client from deriving a second opinion
that could disagree with the ranking it is explaining.
Hosts that fail or are offline are now named above the list. Without that,
"No sessions match" is a claim the app has no basis for.
Gated on server_info.features.agentHistorySearch, checked once against the
connected hosts. Reachability is reported by the banner instead, so one
offline host in the registry no longer hides the field.
