- Expired the per-credential usage report cache after recording observed OpenCode Go spend.\n- Threaded provider base URL into OpenCode Go cost recording so the invalidation targets the same cache key /usage uses.\n- Added regression coverage for refreshing cached OpenCode Go limits immediately after a completed turn.\n\nFixes #2942
- Added an OpenCode Go usage provider that synthesizes 5h, weekly, and monthly cap windows from OMP-observed request costs.\n- Recorded OpenCode Go assistant request costs against the active credential so /usage can report local cap utilization.\n- Added regression coverage for fresh keys and observed spend aggregation.\n\nFixes #2942

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.
- 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).
- Extended session persistence to externalize oversized image payloads in both content and details.images, enabling tool result images to survive session reload.
- 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.
- Guarded `session_stop` continuations against aborted or superseded hook results before queueing hidden follow-up turns.
- Reported compaction recovery continuations from `#checkCompaction` and skipped stop hooks while internal recovery owns the next turn.
- Let terminal empty-stop retry caps fall through to `session_stop` and added regression coverage for aborts, empty-stop caps, and promotion recovery.
- 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.
- Added antigravityEndpointMode setting with auto/production/sandbox endpoint selection.
- Added 429/5xx endpoint failover for Gemini stream, usage, search, and image calls.
- Fixed context breakdown to anchor estimates on the latest completed assistant usage message after compaction.
- Adjusted pending-context usage selection to prefer an in-turn provider anchor when available at/after cutoff.
- Added a contextUsageRevision cache token so status-line context memo invalidates after snapshot clear.
- Added context snapshot metadata to AssistantMessage for prompt and non-message token history.
- Anchored context usage calculations on assistant snapshots and computed percent numerically.
- Updated status-line, /context, selector, and interactive mode flows to share session usage totals.
- Extended status-line cache fingerprinting and invalidation for assistant usage and prompt/tool/skill changes.
- Added `images.describeForTextModels` configuration defaulting to true for text models.
- Added `describeAttachedImagesForTextModel` to persist images and generate local:// descriptions.
- Added image-description notices to session flow with hidden typing and pre-user insertion.
- Added fallback behavior that returns notes when vision is unavailable or output is empty.
Recorded todo reminder developer messages in the session log so JSONL transcripts match model-visible context when reminders are enabled.\n\nFixes #2824
- Sanitized artifact filenames by normalizing tool names before composing spill paths.
- Applied `wrapToolWithMetaNotice` to custom tool adapters and RPC-host tools in agent-session setup.
- Wrapped SDK-registered extension/custom tools with the same meta-notice adapter during session creation.
- Fixed cold revival flow so parked subagents are restored from persisted sessions at startup.
- Fixed session-init persistence to include spawns and readSummarize fields for replay accuracy.
- Fixed latest-session lookup by adding peekSessionInit for lock-free persisted contract access.
- Added lifecycle and session tests for cold-revive success, decline, and retry paths.
- Queued advisor concern cards now get reclaimed as visible advice during settle when auto-resume suppression is active and the session is idle.
- Preserve logic was narrowed to keep advisor cards hidden only during abort teardown, allowing steers during resumed streaming turns.
- A regression test was added to verify stranded advisor steers are persisted as visible advice without triggering an advisor-only resume turn.
Kept shutdown flushes lazy while allowing explicit atomic rewrites to materialize pre-assistant session entries.
Added regression coverage for rewriteEntries before the first assistant message.
Fixes#2800
- Added resolveAdvisorDeliveryChannel in advisor tooling to map each note to aside, steer, or preserve using severity, auto-resume suppression, core-streaming, and abort state.
- Updated AgentSession advice enqueuing to route concern/blocker notes through that resolver, preserving them only when the interrupted turn is idle or tearing down and steering them during active resumed turns.
- Added regression tests for resolveAdvisorDeliveryChannel covering nit versus interrupting severities across streaming, aborting, and suppression combinations.
Prevented shutdown flushes from materializing sessions that never produced assistant output, and kept close from marking a non-existent session file current.
Added regression coverage for opening omp and exiting before any prompt or assistant turn reaches history.
Fixes#2800
- Added LaTeX math and Mermaid allowances in terminal and final-chat prompts.
- Added inline math tokenization in TUI for $, $$, \(\), and \[\].
- Added LaTeX-to-Unicode conversion helpers and exports for math rendering.
- Fixed inline math detection to skip escaped dollars and currency-like spans.
- Rewrote `formatSessionDumpText` in `session-dump-format.ts` to emit the pre-16.x full dump: system-prompt prelude, model/thinking config, tool inventory with parameters, and the transcript as markdown role headings (`## User`, `## Assistant`, `### Tool Call`/`### Tool Result`), reusing `renderDelimitedThinking` for `<thinking>` blocks.
- Dropped the compact default and the `[raw]` flag from `/dump`: removed the `isRaw` parameter from `handleDumpCommand` in `command-controller.ts`, `interactive-mode.ts`, and `types.ts`, and removed the `inlineHint: "[raw]"`/`compact` plumbing in `builtin-registry.ts`.
- Updated the `formatSessionAsText` doc comment in `agent-session.ts` to describe the verbose dump shape.
- Removed the obsolete `formatSessionDumpText raw thinking` suite from `advisor.test.ts` and refreshed `session-dump-format.test.ts` to assert the verbose dump output.
- Recorded the revert in the coding-agent changelog and trimmed `/dump` from the compact transcript tool-intent-prefix entry.
- Introduced advisory note output as `<advisory>` tags with optional severity and guidance.
- Updated session transcript formatting to `### Session update` and inline watched role labels.
- Added shared `escapeXmlText` utility and escaped XML-sensitive text in advisor outputs.
- Added one-shot success run token metrics and one-shot statistics reporting.
