- Assert the eval tool hides disabled backends from the model-facing wire
schema (language enum + field descriptions), summary, and description by
default (rb/jl off), and advertises them once enabled — including the
enabled-subset case.

Filtered failed and incomplete OpenAI Responses image_generation_call items out of native history replay while preserving completed inline results. Added regression coverage for the request shape that produced OpenAI 404s on transient ig_ item ids.\n\nFixes #3225
The login validator pinged `/inference/v1/models`, which Fireworks
serves from the per-account deployment registry and 500s with
`Error listing deployed models` for accounts without active
deployments. Valid `fw_…` keys were rejected during `/login`.
Switched validation to the static control-plane `List Models` API
(`GET /v1/accounts/fireworks/models?filter=supports_serverless=true&pageSize=1`),
the same endpoint discovery already uses. Authentication no longer
depends on the caller owning any deployments.
Fixes#3219
- Refined obfuscation logic to use granular, typed transformations instead of generic object traversal.
- Enforced an 8-character minimum for secret patterns and restricted redaction to user-authored content to prevent false positives.
- Preserved system prompts, tool schemas, and opaque remote replay data to maintain provider context and data integrity.
- Integrated protected snapshot exports with targeted redaction to safeguard sensitive information in shared sessions.
Re-added the isConfigured guard inside applyDefaultSettingOverrides so the
runtime override applied at RPC/ACP startup only fills holes — explicit
embedder/project/--config/global values now survive for task.isolation.{mode,
merge,commits}, task.{eager,batch,maxConcurrency,maxRecursionDepth,disabledAgents,
agentModelOverrides}, memory.backend, memories.enabled, advisor.{enabled,
subagents,syncBacklog,immuneTurns}, plus the RPC-only async.{enabled,maxJobs}
and bash.autoBackground.{enabled,thresholdMs}. The guard was originally added
for #2598 and had quietly regressed, so the override re-asserted the schema
default and clobbered every explicit value — matching the contract problem
#2828 already fixed for the todo paths.
Replaced the prior 'default-disables advisor' test (which codified the
clobbering as the contract) with a comprehensive 'honors explicit
host-defaulted settings' regression covering every contested path across
rpc/rpc-ui/acp.
Fixes#3207
- Enabled Julia language support by adding a sub-syntax definition file.
- Integrated the new syntax into the highlighter by updating the syntax set builder.
- Configured the dependency to support YAML syntax loading via syntect feature flags.
- Introduced `web-palette.ts` to implement the collab-web pink/purple brand identity for HTML exports.
- Updated `generateThemeVars` to support a `palette` option, allowing users to choose between the brand-web aesthetic and a specific TUI theme.
- Configured public exports and the share-viewer script to default to the brand-web palette rather than inheriting the user's terminal theme.
- Refactored `AgentSession.exportToHtml` to align with the new branding defaults while allowing for per-export theme overrides.
- Adjusted `dark.json` background values to ensure better visual consistency across internal surfaces.
Trimmed stored image_generation_call output items before replaying OpenAI Responses native history so provider-only fields like action no longer leak into the next input array.
Added a regression test covering the proxy-rejected replay shape.
Fixes#3201
- Implemented `waitForSelector` and `waitForNavigation` methods in the browser tool API.
- Introduced per-operation fail-fast budget management with dynamic timeout clamping.
- Added validation for selector engines to reject unsupported Playwright-only platform features.
- Standardized error handling to provide descriptive, named timeouts for stalled browser operations.
- Updated model detection to exclude WebP format for Codex-based providers, which do not support it.
- Forced the image resize pipeline to encode to PNG or JPEG for incompatible models to resolve transmission errors.
- Added test coverage to verify that WebP images are re-encoded when using the Codex Responses backend.
- Added extended idle timeouts for Xiaomi MiMo Pro and Alibaba Coding Plan models.
- Updated the stream timeout logic to support these providers, preventing premature stream termination due to long pre-event stalls.
Fixes#1770
- Included the timeout option in the initialization object when prepareInit is absent.
- Ensured that custom timeout settings are preserved for long-running streams instead of being silently dropped.
Fixes#2422
Added clearOptimisticUserMessage and replaceOptimisticUserMessage stubs to the EventController message_start test double so the optimistic-submission case no longer throws when the controller reconciles the signature.
Fixes#3199
Skipped optimistic replacement when a user message_start matches another recorded local submission, preserving the pending prompt bubble until its own expanded event arrives.
Added coverage for the queued-message drain race between startPendingSubmission and prompt dispatch.
Fixes#3199
Updated optimistic replay to track the replacement component handles created during transcript rebuilds, so expanded slash prompts still replace the raw replayed message.
Extended the regression test to cover the rebuild window called out in review.
Fixes#3199
