* feat: port LangSmith LLM Gateway routing from upstream (#1671, #1673, #1674, #1678)
Ports four upstream commits that add opt-in LLM call routing through the
LangSmith Gateway, preserving fork conventions (Bedrock/Fireworks model IDs,
no-agent-attribution, bun toolchain).
- #1671 (e9dc6e01): opt-in gateway routing — new gateway.py, team-settings
toggle, admin UI section, wired into make_model for all graph entrypoints
- #1673 (702ef908): dedicated LANGSMITH_GATEWAY_API_KEY precedence over
platform LANGSMITH_API_KEY
- #1674 (5f7c2f46): fix Fireworks gateway base URL to /fireworks (bare host,
SDK appends /v1/chat/completions) + SanitizeFireworksMessagesMiddleware
- #1678 (73b7d1c0): fix OpenAI Responses reasoning replay —
SanitizeOpenAIResponsesMiddleware, store/include config for encrypted
reasoning content, reasoning_effort coercion for Chat Completions fallback
Refs #134
* fix: downgrade gateway not-routed log to debug, add Bedrock UI note, add sanitizer parity
- Downgrade logger.warning to logger.debug in gateway_overrides for
not-routed providers and missing API key (Bedrock is the default
provider in this fork, so these are expected steady states)
- Add Bedrock to the LLMGatewaySection route-toggle description so
admins know it is not routed through the gateway
- Add SanitizeOpenAIResponsesMiddleware to chat.py for parity with
server.py and reviewer.py
- Restore the Bedrock region comment in model.py that explains the
AWS_REGION / AWS_DEFAULT_REGION precedence
Refs #138

* feat: chat with your PR on the review page
Add a sandbox-less `chat` graph that answers questions about a single PR
from its diff, the published review findings, and read-only GitHub access.
- agent/chat.py: deepagents graph, no sandbox (default StateBackend, file
mutation + execute tools excluded). PR context is seeded as virtual files
under /pr/; a repo-scoped App token is resolved in-graph.
- tools: read_repo_file, search_repo_code, list_review_findings.
- dashboard/review_chat_api.py + routes: per-user chat thread, LangGraph
stream/commands/state/history proxy pinned to the chat assistant, seeds
diff/findings/overview on first run. Gated by repo access.
- UI: Chat tab wired to a chat-scoped StreamProvider (replaces Coming Soon).
* feat: admin setting for review-chat default model
Add a 'Open SWE Review Chat' default to team settings (default_chat_model /
default_chat_reasoning_effort). get_team_default_model("chat") inherits the
Agent default when unset; the chat graph resolves through it. Admin RolePicker
gains an 'Agent default' inherit option that clears the override.
* feat: multi-conversation review chat (tabs, new chat, history)
Replace the single per-PR chat thread with multiple per-user conversations:
- threads minted client-side; first message persists with a title derived
from the prompt.
- list + delete endpoints; chat panel gets a tab strip (history), new-chat
(+), close (x), refresh, an intro greeting, and suggested prompts.
- get_review_chat now returns availability only (ids are client-minted).
* ui fixes
* ui: review-chat history dropdown, full-width AI replies, resizable side panel
* fix(review-chat): enforce per-user thread ownership on proxy endpoints; reseed PR context on head change
