Subject: [PATCH 05/23] test: deflake JWT tamper assertions and fuzzy picker
 widget driver

Tamper tests rewrote the last two base64url characters of the signature,
which on roughly 1 in 250 RS256 tokens (1 in 1000 HS256) only touched
padding bits, so the decoded signature was unchanged and still verified.
Corrupt the decoded signature bytes instead.

The fuzzy picker driver sent keys after fixed sleeps, so a slow worker
could receive the filter text before the widget had highlighted the match.
Wait on the widget's highlighted choice instead.

Subject: [PATCH 09/23] test: deflake guardrail mapping leak, tag routing
 randomness, and liveliness timing

TestStreamingScanDedup restored the reduced module-level translation
mapping on teardown via monkeypatch, so under --dist=loadscope the
worker that ran only that class carried the reduced mapping into the
streaming block test modules. Tag routing tests now assert the eligible
deployment set directly instead of sampling ten random picks. The
liveliness latency check measures steady-state polls after a warm-up
request rather than the first request through a fresh app.

Subject: [PATCH 10/23] test: deflake redis loop-stall burst test and
 pre-commit interrupt cleanup

The redis breaker test raced the event loop: the fake call had to still be
pending when a real time.sleep stall began, which needs the loop to get from
scheduling to the stall in under 1ms. The fake now holds its answer behind an
asyncio.Event so the whole burst times out deterministically.

The pre-commit interrupt test found a real leak: lint_dashboard creates its
eslint report with mktemp and only removed it on the happy path, so an
interrupt landing during the whole-folder eslint run left the file behind.
The subshell now removes it from an EXIT trap, and the test drives the
interrupt while that eslint run is in flight.

 group responses

The access group detail page rendered MCP servers, agents, attached teams and keys as bare ids, so an admin had to look each one up elsewhere to audit a group

Every access group response now also carries access_mcp_servers, access_agents, assigned_teams and assigned_keys as {id, name} pairs. Names come from the DB rows first and fall back to config-declared MCP servers and agents (including legacy agent ids), resolved with one query per table across all groups in a list call. The existing *_ids columns are unchanged

The UI renders the name with the id in a tooltip, links teams and keys to their detail pages, and shows the raw id only when nothing resolves

Subject: [PATCH 18/23] feat(complexity_router): let the LLM classifier see
 request images (#39825)

The classifier scores extracted text, so a turn whose complexity lives in
its image is invisible to it: a screenshot of a stack trace classifies on
its caption, and an image-only turn flattens to empty text and never
reaches the classifier at all.

classifier_llm_config.vision opts in, off by default, with max_images
bounding what one turn can add. Images are still dropped when the
classifier model is declared supports_vision false. Anthropic and
Responses image parts are rewritten into chat-completions dialect before
they reach the classifier call, since /v1/messages hands the pre-routing
hook its own dialect untranslated.

The local scorer no longer short-circuits heuristic_first or hybrid on a
turn carrying forwarded images, because it reads text alone and its
confidence describes a request it has only partly seen.

* feat(otel): stamp litellm.request.route on the LLM call span

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* refactor(otel): drop redundant comment on REQUEST_ROUTE

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* style(otel): Final-annotate route test locals, drop field comment

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(otel): read litellm.request.route off the server span

The LLM call span took the auth-normalized literal path from logging
metadata, which disagrees with the SERVER span wherever FastAPI matched a
template: on /engines/{model:path}/chat/completions the LLM span spelled the
model name while http.route carried the template, so the two spans grouped
into different buckets and the PR's premise did not hold.

Read the value off the span that already holds it. The request's root SERVER
span is anchored per request for parenting, and its attributes stay readable
after it ends, so request_root_http_route() answers from the async close
callback with the same http.route the SERVER span exports: the route template
on a normal route, the literal path where the passthrough hook rewrote it, and
the mount point on an MCP call. Nothing has to re-derive any of that, so the
two spans cannot drift apart.

The route the proxy recorded at auth stays as the backstop for a deployment
whose FastAPI instrumentation never mounted, where there is no server span to
disagree with. Off the proxy the attribute is omitted rather than empty.
