- Derive replay session from generateStableSessionID when sessionId is absent
- Merge cached thoughtSignature into existing functionCall by call id
- Allow filter to pass function_call_part when only signature replay is needed
- Include native functionCall id in replay dedupe keys
- Add unit tests for signature merge, stable scope, and parallel tool ids
Trim call_id once for matching-function-response checks; use args.Value()
in synthetic model functionCall insertion; guard functionResponse lookup
when call_id is empty.
When HOME replay restores a cached function_call_part and the request
already contains the matching functionResponse, insert a synthetic
role=model content with functionCall (and thoughtSignature) immediately
before that response content instead of writing into the same index.
Add regression tests for user/model functionResponse shapes.
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.
Update AntigravityUserAgent helpers and executor default UA comment to match.
