This change introduces a new `openrouter` API type and extensively refactors OpenAI-family streaming providers, centralizing shared logic and improving robustness.
Key changes include:
- **Unified OpenAI-family Logic:** Consolidated core utilities, compat resolution, request shaping, and stream processing into `openai-shared.ts`, reducing duplication across `openai-completions`, `openai-responses`, and `openai-codex-responses`.
- **OpenRouter API Type:** Introduced a dedicated `openrouter` API type with dual-surface compatibility, allowing it to dispatch requests as either OpenAI Chat Completions or Responses.
- **Enhanced Provider Integration:**
- Improved Perplexity search to leverage shared OpenAI streaming transports, including API-key fallback to OpenRouter and support for Perplexity's Responses API.
- Integrated xAI-specific logic directly into the shared `stream.ts` dispatch, removing the dedicated `xai-responses` provider.
- Refined credential parsing for Google Gemini CLI and handling of Azure deployment names.
- **Robustness & Consistency:** Improved error handling for Codex, standardized output token parameter resolution, and ensured consistent application of reasoning suppression across all Chat Completions dialects.
- **New Documentation:** Added `provider-endpoint-constraints.md` to detail endpoint-specific behaviors and quirks for various providers.
- **Telemetry & Debugging:** Extended telemetry propagation to advisor calls and overflow compaction tasks. Improved debugging for Codex WebSocket failures and stream error messages.
- **Tooling & Security:** Updated browser stealth scripts to prevent detection and added a new `ts-no-inline-cast-access` TTSR rule.
- Bound native Reflect methods to local variables in the browser launch script to prevent detection.
- Updated stealth injection scripts to use the bound Reflect methods instead of global Reflect calls.
- Fixed a type assertion issue in the AgentSession tool proxy.
- Added a new builtin rule definition file, `ts-no-inline-cast-access.md`, with AST patterns that flag inline cast member access and usage guidance.
- Registered the new rule in `src/discovery/builtin-rules/index.ts` so it is included in the built-in TypeScript rule set.
- Updated `ts-no-any.md` to recommend schema parsing at trust boundaries and clarified when to choose schema parsing, guards, or unchecked casts.
- Added a top-level `ttsr` CLI command with `list` and `test` actions.
- Added snippet input handling for inline text, `--file` path, and stdin via `--file -`.
- Added test-mode context inference and result output for matched and unmatched rules.
- Added CLI tests for source inference, explicit source overrides, JSON output, and list mode.
- Wrapped MCP call and result renderers in WidthAwareText so formatting can use runtime content width.
- Computed inline argument preview budget from the available content width instead of a fixed 70-character cap.
- Updated raw text truncation in MCP results to target the measured content width while preserving expand hints and warnings.
- Introduced a WidthAwareText component that formatted fallback content during render using the computed content width.
- Updated ToolExecutionComponent to use WidthAwareText and invalidate cached text instead of a fixed-width Text path.
- Reworked generic tool output formatting to derive inline and output truncation budgets from terminal width rather than hard-coded 70/80 columns.
- Added PDF member read syntax (`doc.pdf:<member>`) and trailing-colon listing.
- Added asset-read handling to serve extracted PDF images as inline image content.
- Added PDF image extraction caching keyed by size and mtime with marker files for retries.
- Added basename validation that rejects unknown/traversal-like PDF members and shows available names.
- Added new `tui.tight` setting with default `false` and documented behavior.
- Added global tight-mode APIs and `setIgnoreTight` propagation across Box, Text, and Markdown.
- Handled `tui.tight` updates to refresh UI borders and trigger rerendering.
- Updated key message components to ignore tight mode selectively and preserve intended spacing.
- Removed ANTIGRAVITY_NO_PREAMBLE_INSTRUCTION from the shared Gemini header constants.
- Updated Gemini CLI and web search request builders to prepend only ANTIGRAVITY_SYSTEM_INSTRUCTION before existing system parts.
- Adjusted the Gemini CLI alignment test to stop asserting the removed anti-preamble prompt lines.
- Changed provider delta input comparisons in `buildResponsesDeltaInput` to use `Bun.deepEquals` instead of stringified JSON checks.
- Updated session message diffing to return early on length changes and compare normalized entries with deep equality.
- Replaced JSON-string assertions in the issue-966 repro test with `Bun.deepEquals` for stable equality checks.
- Tracked completed primary turns in `AgentSession` and started an immune-turn window after each interrupting advisor steer.
- Routed follow-on `concern`/`blocker` notes to the aside channel while the immune window is active, while preserving prior auto-resume-suppressed handling.
- Added the `advisor.immuneTurns` setting and tests for immune-turn detection and delivery-channel decisions.
- Added Matplotlib figure PNG rendering and display tracking in Python runner to emit PNG output immediately when figures are displayed via display(fig).

- Enhanced session loader to resolve image data payloads and blob references across content and details.images during session reconstruction.
- Added image cache invalidation in TUI image component when image protocol, cell dimensions, or Kitty Unicode placeholder mode changes.
- Added comprehensive test coverage for Matplotlib display, image persistence across reload, and TUI image rendering with protocol and dimension changes.
- Updated `executeSearch` to read `providers.antigravityEndpoint` once and catch uninitialized-settings errors, so web search fallback no longer aborts before any provider runs.
- Added missing `Vision` and `Git` entries to `TAB_GROUPS` so those new settings now render in their intended setting-section groups.
- Adjusted context and idle-compaction tests to wait for prompt-in-flight transitions and provide `getContextUsage` for deterministic snapshots during pending turns.

- Added `sdk-dialect` coverage for unclassified tool-less models alongside MiniMax preferred dialect routing.
- Updated the coding-agent changelog entry to mention MiniMax auto-mode routing.
- Routed `resolveDialect("auto")` through `preferredDialect(model.id)` when a tool-less model exposes an id, preserving the legacy GLM fallback for id-less models.
- Added `sdk-dialect` coverage for MiniMax and Qwen auto owned dialect selection while keeping native and explicit dialect behavior unchanged.
- Updated getApiKey signatures to accept a Model and return ApiKey or ApiKeyResolver.
- Updated stream key handling to resolve credentials per model and use seedApiKeyResolver for retries.
