@oh-my-pi/pi-ai

Dropped unsigned thinking blocks from Antigravity Claude requests instead of sending them without a signature, preventing HTTP 400 responses when resuming sessions or switching models.
Classified Antigravity HTTP 429 responses from structured google.rpc.ErrorInfo reasons (QUOTA_EXHAUSTED, RATE_LIMIT_EXCEEDED, and INSUFFICIENT_G1_CREDITS_BALANCE), using retry delays of five minutes or longer to distinguish rotatable quota windows from transient throttling instead of relying only on message regexes.

Removed the Antigravity identity-prompt injection (ANTIGRAVITY_SYSTEM_INSTRUCTION and shouldInjectAntigravitySystemInstruction): Cloud Code Assist accepts arbitrary system instructions on gemini-3.x and Claude routes (verified live), and the injected stub never matched the real client's system prompt anyway. User system prompts are now sent unmodified (still tagged role: "user").
Fixed Antigravity auto mode not failing over to the sandbox endpoint when the daily endpoint returned a thinking-only STOP, which caused Advisor turns to be falsely recorded as empty-response failures (#8480).

Added support for the deepseek-v4-pro:preview model
Added support for the gemini-3.7-flash model
Added dynamic Antigravity client-version discovery from the official update manifest (darwin/arm64 channel), so version-gated models appear without a code change; PI_AI_ANTIGRAVITY_VERSION remains available as an override.

Fixed Antigravity discovery missing Gemini 3.7 Flash: Cloud Code Assist gates newer models on the client version in the User-Agent, and the pinned antigravity/hub/2.1.4 was too old. The user-agent now matches the captured 2.8.0 client format (antigravity/hub/2.8.0 (aidev_client; os_type=darwin; arch=arm64; cl=963137146)); os_type/arch stay pinned to the darwin/arm64 reference client. Overridable via PI_AI_ANTIGRAVITY_VERSION / PI_AI_ANTIGRAVITY_CL / PI_AI_ANTIGRAVITY_OS / PI_AI_ANTIGRAVITY_ARCH.

Removed ANTIGRAVITY_SYSTEM_INSTRUCTION from wire/gemini-headers; the Antigravity transport and web search no longer inject a fake identity prompt.

Fixed the parent TUI stalling after a subagent submits its result until terminal focus or resize wakes the event loop (#8462).
Fixed omp update misclassifying foreign npm/bun bin aliases while preserving package-manager ownership for globally linked checkouts (#8468).
Fixed read hashline headers collapsing nested in-workspace paths to the bare basename, which let a same-basename file at the session cwd capture a verbatim follow-up edit and deterministically reject it with hash is not from this session. Headers now retain the workspace-relative path (e.g. [src/settings.json#0063]) (#8482).

Fixed fetchWithRetry() aborts during retry backoff to preserve the documented "Request was aborted" error contract (#8450).
