Universal Chat Provider is a VS Code extension that surfaces Claude,
ChatGPT/Codex, Antigravity, Grok, and Kimi subscriptions as native
language models in GitHub Copilot Chat, using CLIProxyAPI as a fully
managed background server.

- Introduced `activeRecords` and `activeRecordsFromSnapshot` to filter current plugin records more efficiently.
- Updated all instances of `Snapshot().records` across code and tests to use `activeRecords`.
- Added additional checks for `recordCurrent` and plugin identity validation in several plugin capability calls.
- Enhanced test logic to validate `activeRecords` usage and ensure consistent behavior.
* fix(oauth): force-map responses to config alias not request suffix
Rewrite client-visible model fields using oauth-model-alias Alias from config
(e.g. gpt-5.4-fast) instead of mirroring the requested model string when the
client adds thinking suffixes (e.g. gpt-5.4-fast(high)). Upstream routing
still preserves suffixes on the resolved upstream model.
* test(oauth): gate response rewrite on ForceMapping and document OriginalAlias
- Document that OriginalAlias is only applied when ForceMapping is true
- Set OriginalAlias to config alias only when force-mapping is enabled
- Add tests: no non-stream/stream payload rewrite when ForceMapping is false
* test(oauth): assert disabled force mapping response
- Introduced `model` field in `videoAuthBinding` for model tracking.
- Enhanced binding store with `setWithModel` and `getBinding` methods for binding models.
- Updated handlers to propagate execution models during video processing.
- Added tests to verify model binding, retrieval, and propagation logic.
Add OAuthModelAlias.ForceMapping to rewrite client-visible model fields in non-stream and SSE stream responses while leaving request-log upstream payloads unchanged.
- Wire config, watcher diff, and conductor execute/stream paths
- Rewrite force-mapped responses in Antigravity credits fallback paths
- Prevent buffered SSE chunks from being emitted by line-wise fallback
- Preserve thinking suffixes for same-base force-mapping aliases
- Cover codex, antigravity, kimi, and xai with live-derived fixtures and regression tests
- Document a conservative antigravity-only force-mapping example in config.example.yaml
Direct OpenAI image calls can inherit downstream User-Agent values from the Gin request context, which may trigger upstream Cloudflare 1010 blocks.
Clone inbound Codex headers for direct image requests and remove only User-Agent before applying defaults. This keeps Version, X-Codex-Turn-Metadata, X-Client-Request-Id, and Originator forwarding intact.
Expand direct image regression coverage for downstream identity headers and align edit endpoint expectations with /images/edits.

- Replaced legacy fallback logic with normalized attribute-based handling in `AuthKind`.
- Consolidated metadata inspection for both API key and OAuth attributes.
- Updated calls to replace direct `AccountInfo` usage with `AuthKind` and `AuthSourceKind`.
- Enhanced unit tests to validate explicit and fallback credential resolution scenarios.
- Added NodeID field to HomeConfig for better identification.
- Updated ConfigFromJWT to populate NodeID from claims.
- Introduced new Redis keys for managing plugin status and tasks.
- Implemented RPushPluginStatus and GetPluginTasks methods in the client for handling plugin-related data.
- Enhanced Sync functionality to include detailed reporting on plugin installation and deletion tasks.
- Added error handling and reporting for plugin synchronization failures.
- Created tests for new plugin synchronization and management features.
- Improved the overall structure and readability of the plugin synchronization logic.
Add Grok-native reasoning replay for Claude-sourced xAI Responses requests. Replay state is scoped by model and session, normalized to reasoning/function_call/custom_tool_call items, and injected with the same tool-call alignment semantics used by Codex.
Include the minimal Grok encrypted_content validator needed on upstream/dev so replay cache entries cannot accept Codex/GPT, Gemini, or Claude signature shapes. Cache completed output items from HTTP, streaming, and WebSocket xAI responses.
Cover two-turn Claude replay, tool_result continuity, valid Grok cache storage, and rejection of Codex-shaped encrypted_content.
* Drop foreign encrypted_content before xAI Grok upstream
xAI Grok accepts provider-native encrypted_content as opaque replay state, but GPT/Codex reasoning signatures, Gemini thoughtSignature blobs, and Claude thinking signatures can all travel through OpenAI Responses-style reasoning.encrypted_content while remaining incompatible with xAI. Forwarding those foreign blobs to Grok causes upstream validation failures, especially when the foreign value is high-entropy enough to look ciphertext-like.
Add a Grok encrypted_content transport validator that stays conservative and shape-oriented:
- require unpadded standard base64 with no foreign characters
- reject obvious GPT/Codex gAAAA reasoning signatures before decode
- reject strict Claude thinking signatures in both official E-form and Antigravity R-form
- reject known Gemini thoughtSignature envelopes by reusing the central Gemini validator, covering Gemini 2.5 field-1 and Gemini 3.x field-2 shapes
- require decoded payloads to be long enough and high-entropy enough to look like native Grok ciphertext
- avoid decrypting, protobuf-parsing, or otherwise interpreting native Grok payloads on the hot path
Wire the validator into the xAI Responses request preparation path for reasoning and compaction input items. Invalid encrypted_content fields are deleted before the request is sent upstream, while the surrounding item is preserved and debug logging records only redacted metadata.
Extend coverage with native Grok corpus preservation, Gemini field-1/field-2 rejection, Claude E-form and R-form rejection, invalid-blob sanitizer tests, and compact/websocket replay preservation. The foreign-provider checks are deliberately narrow so high-entropy Grok blobs are not rejected merely because they look random.
