Add executor-scoped replay cache aligned with Codex HOME replay:
Scope, observe SSE/non-stream responses, store normalized thought_signature
and function_call_part items, apply on the next streamGenerateContent
request, and invalidate on invalid signature responses.
Gemini/flash/agent models use HOME replay; native per-part signature
replay is not wired on upstream/dev. Wire non-stream and stream paths
in antigravity_executor and purge expired entries from signature_cache.
Includes unit tests and HOME-provider-replay documentation.

Use the agy CLI User-Agent family (antigravity/cli/{version} darwin/arm64)
on CPA macOS/arm64 hosts instead of the legacy hub-style antigravity/{version}
string. Resolve the cached version from the CLI auto-updater manifest
(darwin_arm64.json), then the GCS latest pointer, then antigravity-cli GCS
prefix listing, with fallback 1.0.8 when all sources fail.

Adds a fourth value for the disable-image-generation setting:
- false: inject image_generation (unchanged)
- true: strip everywhere + 404 on /v1/images/* (unchanged)
- chat: strip on non-images endpoints, keep /v1/images/* (unchanged)
- passthrough: never inject and never strip on non-images endpoints
(the client payload is forwarded unchanged); behaves like
"chat" on /v1/images/* endpoints.
image_generation injection (codex executors) is already gated on the Off
mode, and the /v1/images/* 404 gate is already gated on the All mode, so
passthrough only required a change to the payload strip logic in
payload_helpers.go, now expressed via shouldStripImageGeneration().

Add a native Antigravity WebSearch path for Claude typed WebSearch requests.
Detect Claude Messages requests whose tools are only typed WebSearch tools
(web_search_20250305 / web_search_20260209), and convert them into an
Antigravity requestType=web_search payload instead of sending the request
through the normal tool-calling path.
Preserve the user's requested model. The native path is enabled only when that
Antigravity model is known to support Google Search. Capability data fetched
from Antigravity model info is used only as an enhancement to the local model
registry, not as a replacement for the existing registry fallback behavior.
Unsupported models keep the existing Antigravity request behavior and are not
silently rerouted to another web-search-capable model.
Translate Claude WebSearch request options to the verified Antigravity
googleSearch shape:
- max_uses -> googleSearch.enhancedContent.imageSearch.maxResultCount
- allowed_domains -> googleSearch.includedDomains
Leave blocked_domains and user_location unmapped because the Antigravity
googleSearch request shape has no verified equivalent for them. This avoids
sending speculative fields or pretending unsupported Claude WebSearch options
are enforced upstream.
Translate Antigravity web-search responses back into Claude-compatible output:
server_tool_use blocks, web_search_tool_result blocks, cited text blocks,
grounding URLs, and usage-compatible stream/non-stream responses.
Cover the behavior with tests for request conversion, response conversion,
grounding URL resolution, domain filter mapping, fetched capability hints,
excluded-model handling, and unsupported-model behavior.
- Added an example plugin `host-model-callback` in Go to summarize host model callbacks.
- Implemented `cliproxy_plugin_init`, `cliproxyPluginCall`, and other plugin functions for callback handling.
- Introduced API handlers for `ModelExecution` and `ModelExecutionStream` with support for both streaming and non-streaming requests.
- Included unit tests (`model_execution_test.go`) to validate execution logic and streaming responses.
Apply review feedback on codexExtractImageResults: preallocate the results
slice to its known maximum capacity to avoid growth reallocations, and guard
the itemsByIndex index-build/sort with a length check so no empty slice is
allocated or sorted when only the fallback items are present.
The OpenAI images path (/v1/images/*) previously called patchCodexCompletedOutput
to concatenate collected output_item.done items back into the completed event and
then re-parsed that rebuilt JSON to pull out the image results. For multi-megabyte
base64 image payloads this produced two extra full-size copies per request (the
concatenated output array plus the rebuilt completed event), inflating peak memory
under concurrent image generation.
Add codexExtractImageResults, which extracts image_generation_call results directly
from either the completed event's response.output or the collected items, without
the concatenate-and-reparse step. Semantics are preserved: completed output is
preferred and collected items are used only when it is empty, matching the original
patchCodexCompletedOutput behaviour. patchCodexCompletedOutput remains in use by the
text/responses path, which still forwards the patched event downstream.
Adds unit tests covering the completed-output path, the ordered fallback to
collected items, output preference, fallback list, and the wrong-event-type guard.

- Added unit test to validate context-based RoundTripper behavior.
- Replaced `NewProxyAwareHTTPClient` with `NewUtlsHTTPClient` in relevant executors for improved TLS fingerprinting.
Closes: #3680

Stop retrying when Home dispatch returns an auth that already failed within the same request.
- Replaced `NewUsageReporter` with `NewExecutorUsageReporter` to include executor type in usage records.

- Removed legacy support for deprecated `Conversation_id` header to clean up API.
- Modified `applyCodexIdentityConfuse*` functions to include `turn_id` and `window_id` in metadata transformations.
- Updated test cases to validate the inclusion and restoration of these fields.
- Removed deprecated `Conversation_id` header support and related logic for cleaner implementation.
When Claude Code sends a stop-hook evaluator request (or any request
without tools), the payload includes "tools": [] (empty array). The
claude->codex translator unconditionally emits tools: [] + tool_choice:
"auto" + parallel_tool_calls: true into the Codex Responses shape.
When that payload is routed to xAI, the upstream rejects with HTTP 400:
"A tool_choice was set on the request but no tools were specified."
Fix entirely in the xAI executor (translator package is policy-locked):
add normalizeXAIToolChoiceForTools() after normalizeXAITools() to drop
tool_choice and parallel_tool_calls whenever tools end up absent or
empty (covering both the empty-from-source case and the
all-filtered-out case where every tool was an unsupported type such as
tool_search or image_generation).
Per code-review feedback: always remove parallel_tool_calls when tools
are missing (not gated on tool_choice presence) and existence-check
each key before sjson delete to avoid unnecessary JSON parse/copy.
Verification:
