* fix: resolve provider alias before matching _PROVIDER_MODELS (#6148)
* fix(backend): resolve model prefix through _PROVIDER_ALIASES before matching
- Fix IndentationError: dedent _canon_prefix assignment to 8 spaces
- Rebased onto upstream/master
- Add regression test: alias prefix (z-ai) resolves to canonical key (zai)
and routes cross-provider through OpenRouter (#6131)
* fix(#6131): canonicalize both sides via _canonicalise_provider_id (idempotent) + regression tests
Codex found _resolve_provider_alias breaks Qwen (qwen->alibaba, not in _PROVIDER_MODELS)
and cross-routes alias-of-active-provider (raw vs canon asymmetry). Use the idempotent
_canonicalise_provider_id for both membership and equality. Adds 2 regression tests.
* docs(changelog): stamp #6148 alias-prefix model routing fix

* fix(#6389): remove clear_offline_buffer() teardown blocks that cause data loss on late reconnects
Keep the real leak fixes:
- unregister_stream_owner() in both streaming.py and gateway_chat.py
- AGENT_INSTANCES.pop() in gateway_chat.py
The clear_offline_buffer() calls could clear a channel's offline buffer
after a late reconnect already fetched the channel but before it subscribed,
causing the reconnecting client to lose all buffered events (including
stream_end) and hang indefinitely on heartbeats.
STREAMS.pop() already releases registry ownership; GC reclaims the buffer
once the last outstanding channel reference is dropped, correctly preserving
replay for in-flight reconnects.

* fix: Fix height of consolidated kanban board
There was a lot of empty space below the kanban board columns
in the condolidated view (particularly on desktop). Modify the
CSS such that the consolidated view always fills the viewport
vertical space.

* fix: Fix kanban scrolling in mobile viewports
Scrolling vertically (particularly in expanded view) in kanban on
a mobile viewport is difficult. The columns have overscroll
disabled, meaning tap and drag will only scroll within the column
and will not continue to the next section. On desktop it's much
easier to get the mouse outside the column div, on mobile you have
to deliberately try to tap very close to the edge of the viewport.
Disabling that behavior makes the experience much better

* fix(webui): keep the content search from evicting the user's working set
/api/sessions/search?content=1 walks EVERY session and pulls each one through
get_session(), which inserts it into the SESSIONS LRU and marks it
recently-used. On any install with more sessions than sessions_cache_max
(default 300), a single search therefore flushes the whole cache and refills it
with sessions the user is not looking at — the classic buffer-pool
scan-pollution problem. The sessions actually open in the UI are exactly the
ones evicted, and the search is keystroke-debounced, so it repeats while typing.
A scan reads each session exactly once, so nothing it touches has earned
"recently used". get_session_for_scan() reuses a resident session without
promoting it, and reads a cold one straight from disk without caching it. It
returns None rather than raising, since a scan skips what it cannot open.
This is a correctness fix for cache behaviour, not a latency fix. The
multi-second searches that led here were contention, not scan cost: a trivial
/api/profiles took 9.2s in the same window, and a full read+parse of ~1700 real
sessions measures ~4s total.
test_sessions_search_depth_validation patched api.routes.get_session. With the
search reading through the scan accessor it now patches get_session_for_scan —
left unfixed, two of its cases fail and the third passes vacuously against an
empty result set.
Validation:
pytest tests/test_issue4765_sessions_lru_eviction.py
tests/test_sessions_search_depth_validation.py -> 13 passed
Both added eviction tests fail on the pre-fix accessor (verified by revert):
the working set drops from 4/4 to 0/4 resident after one scan.

* feat(terminal): broadcast output to every viewer instead of one shared queue
TerminalSession.output was a single queue.Queue read destructively by the SSE
handler. Two tabs/windows viewing the SAME session each open their own
EventSource, so two _handle_terminal_output handlers competed on that one queue:
every PTY chunk was delivered to exactly one of them. Each tab saw a disjoint
half of the byte stream, and only one ever received terminal_closed.
Output now fans out, mirroring StreamChannel/SessionChannel: each SSE consumer
subscribe()s its own queue (seeded with a bounded backlog so a first/late attach
still replays the recent scrollback, preserving the old buffer-until-first-
consumer behaviour), and put_output broadcasts to all subscribers. A slow
viewer's queue drops its own oldest chunk (drop-oldest, isolated per subscriber)
so one lagging tab can't starve another. The handler unsubscribes in a finally
so the subscriber list can't grow.
Stacked on the terminal fd-leak fix (same file).

Per maintainer review, the try/except wrapper is defense-in-depth only —

Updated log message and added inline comment to make this explicit.

* perf: optimize large session reconnect by adding file-size threshold to tail optimization (#6241)
When a sidecar JSON file exceeds 500 KB, the display-path tail optimization
now fires even if the message count is within the raw_budget. This prevents
sessions with few messages but large tool outputs (multi-MB JSON) from
forcing a full-scan merge of all messages on reconnect.
Changes:
- Added _sidecar_file_exceeds_threshold() helper
- Added _SIDECAR_BYTE_TAIL_THRESHOLD = 500_000 constant
- Fall-through to truncation in _state_db_since_timestamp_for_limited_display
when the sidecar file exceeds the threshold, regardless of message count
* CHANGELOG: byte-size reconnect tail optimization (#6260)
