downgradeOpenAIReasoningBlocks was only called on model change, but
orphaned reasoning items (e.g. from an aborted stream) can exist without
a model switch and cause a 400 from the OpenAI Responses API.

The Cloud Code Assist API rejects anyOf/oneOf in tool schemas, not just
unsupported keywords. The image tool (index 21) had:
image: { anyOf: [{ type: "string" }, { type: "array" }] }
which caused "JSON schema is invalid" errors when forwarded to Anthropic
via google-antigravity.
simplifyUnionVariants only handles literal unions and single non-null
variants. This adds a fallback in cleanSchemaForGeminiWithDefs that
flattens any remaining anyOf/oneOf to a simple type schema.
Also reverts the previous provider-aware normalizeToolParameters and
sanitizeToolsForGoogle changes, which were incorrect — the cleaning IS
needed for Google's API regardless of which downstream model is used.

google-antigravity serves Anthropic models (e.g. claude-opus-4-6-thinking),
not Gemini. sanitizeToolsForGoogle was stripping JSON Schema keywords
(minimum, maximum, format, etc.) needed for Anthropic's draft 2020-12
compliance, causing "JSON schema is invalid" rejections on tool 21
(web_search).
This was the actual root cause — the earlier normalizeToolParameters
fix was being overridden by this second sanitization pass.

Two fixes for Google Antigravity (Cloud Code Assist) reliability:
1. Forward-compat model fallback: pi-ai's model registry doesn't include
claude-opus-4-6-thinking. Add resolveAntigravityOpus46ForwardCompatModel()
that clones the opus-4-5 template so the correct api ("google-gemini-cli")
and baseUrl are preserved. Fixes#13765.
2. Fix thinking.signature rejection: The API returns Claude thinking blocks
without signatures, then rejects them on replay. The existing sanitizer
strips unsigned blocks, but the orphaned-user-message path in attempt.ts
bypassed it by reading directly from disk. Now applies
sanitizeAntigravityThinkingBlocks at that code path.

* fix(ui): allow relative URLs in avatar validation
The isAvatarUrl check only accepted http://, https://, or data: URLs,
but the /avatar/{agentId} endpoint returns relative paths like /avatar/main.
This caused local file avatars to display as text instead of images.
Fixes avatar display for locally configured avatar files.
* fix(gateway): resolve local avatars to URL in HTML injection and RPC
The frontend fix alone wasn't enough because:
1. serveIndexHtml() was injecting the raw avatar filename into HTML
2. agent.identity.get RPC was returning raw filename, overwriting the
HTML-injected value
Now both paths resolve local file avatars (*.png, *.jpg, etc.) to the
/avatar/{agentId} endpoint URL.
* feat(compaction): add adaptive chunk sizing and progressive fallback
- Add computeAdaptiveChunkRatio() to reduce chunk size for large messages
- Add isOversizedForSummary() to detect messages too large to summarize
- Add summarizeWithFallback() with progressive fallback:
- Tries full summarization first
- Falls back to partial summarization excluding oversized messages
- Notes oversized messages in the summary output
- Add SAFETY_MARGIN (1.2x) buffer for token estimation inaccuracy
- Reduce MIN_CHUNK_RATIO to 0.15 for very large messages
This prevents compaction failures when conversations contain
unusually large tool outputs or responses that exceed the
summarization model's context window.
* feat(ui): add compaction indicator and improve event error handling
Compaction indicator:
- Add CompactionStatus type and handleCompactionEvent() in app-tool-stream.ts
- Show '🧹 Compacting context...' toast while active (with pulse animation)
- Show '🧹 Context compacted' briefly after completion
- Auto-clear toast after 5 seconds
- Add CSS styles for .callout.info, .callout.success, .compaction-indicator
Error handling improvements:
- Wrap onEvent callback in try/catch in gateway.ts to prevent errors
from breaking the WebSocket message handler
- Wrap handleGatewayEvent in try/catch with console.error logging
to isolate errors and make them visible in devtools
These changes address UI freezes during heavy agent activity by:
1. Showing users when compaction is happening
2. Preventing uncaught errors from silently breaking the event loop
* fix(control-ui): add agentId to DEFAULT_ASSISTANT_IDENTITY
TypeScript inferred the union type without agentId when falling back to
DEFAULT_ASSISTANT_IDENTITY, causing build errors at control-ui.ts:222-223.
* Agent: exclude google-antigravity from history downgrade hack
* Lint: fix formatting in test
* Lint: formatting and unused vars in test
* fix: preserve google-antigravity tool calls (#894) (thanks @mukhtharcm)
