Migrate off direct provider APIs: AWS Bedrock for Anthropic/Claude via the
cross-region inference profile us.anthropic.claude-opus-4-8, Fireworks AI for
all non-Claude models. Drop OpenAI (gpt-5.5) and Google (gemini-3.5-flash)
entirely. DEFAULT_MODEL_ID is now Bedrock Claude; all Fireworks models stay
freely selectable for the agent and reviewer graphs and via team/profile
defaults.
- pyproject: add langchain-aws (ChatBedrockConverse + boto3)
- options.py: Bedrock Claude entry + default; remove openai/google entries
- model.py: bedrock_converse provider_model_kwargs (effort -> thinking budget),
region pin in make_model, bedrock<->fireworks fallback pairing, AWS_REGION/
FIREWORKS_API_KEY local-dev validation
- server.py: provider-aware fallback kwargs build
- sanitize_thinking_blocks: also sanitize ChatBedrockConverse thinking blocks
- model_fallback: treat transient botocore ClientError codes as fallback-worthy
- eval_jobs: repoint hardcoded eval model id to Bedrock Claude
- tests: repoint dropped model ids; drop obsolete google test module
* feat: AI-sorted PR review view with diff grouping
Group a PR's changed files into a logical top-to-bottom walkthrough via a best-effort structured-output LLM pass, kicked off concurrently with the reviewer run (~0 added latency) and persisted on reviewer thread metadata. Results render in the review UI behind an AI sorted / file tree toggle that persists across PRs; the view falls back to the file tree when groups are absent or stale.
Adds a grouping-model team default (inherits the Reviewer subagent model when unset) and the admin RolePicker for it.
* feat(reviews): richer AI-sorted explanations + sidebar polish
Sidebar group rows get Devin-style spacing (dividers, padding), a per-group file list (click a file to jump to its diff), inline-code chips in titles, and an accent Read explanation link.
Group explanations are now rich markdown: the grouping prompt feeds per-hunk line ranges and asks for inline code, a short code block, and [path:line](#loc=...) references. The Markdown renderer turns those #loc= links into in-page buttons that scroll the diff to the hunk and highlight the range, reusing the existing selectedLines path.
* fix(reviews): drop stale diff groups from the AI-sorted view
When groups were generated for a previous head, a persisted "ai" view in localStorage still rendered the outdated walkthrough. groupedView now returns null on diff_groups_stale, so the file-tree fallback is used and the view toggle hides until fresh groups arrive.
