felixxia-oai 4636819a35 Harden Guardian reviews after context compaction (#42852)
## Why

Guardian reviews must not lose user authorization constraints or reuse an
unreadable or incompatible parent checkpoint after compaction.

## What changed

- Retain bounded excerpts of oversized root user messages across compaction,
  resume, and rollback, and recover excerpts from legacy Guardian history when
  available.
- Require thread-owned Guardian review sessions and asynchronous scoring to
  reuse only non-empty checkpoints produced by a compatible review model.
- Fail closed instead of reviewing without the required checkpoint when reuse
  is disabled, compatibility is unknown, or checkpoint content is unusable.

## Testing

Expanded retained-context, review-session, asynchronous-scoring, and app-server
coverage for oversized instructions, legacy recovery, model incompatibility,
missing content, resume, rollback, and disabled checkpoint reuse.

felixxia-oai 9c4253ffc1 Retain user instructions in Guardian context (#42844)
## Why

Guardian reviews need the original user instructions even when compaction or
transcript selection removes them from the active conversation window.

## What changed

- Capture complete user messages in host-owned retained context and include them
  as ordered authorization evidence alongside verified answers.
- Omit oversized instructions atomically and emit an explicit incomplete-evidence
  notice instead of exposing a potentially misleading partial permission.
- Mark user messages inherited by forked agents so they remain model-visible
  without becoming child-local authorization.

## Testing

- Cover retained instructions across compaction, resume, rollback, and agent
  forks, including oversized evidence and legacy context behavior.

felixxia-oai 99d66aa1c5 Preserve acceptance order in retained thread context (#42770)
## Why

Queued prompts and `request_user_input` answers can be persisted in a different
order from when the host accepted them. Using persistence order can therefore
reorder retained instructions during replay or apply the wrong rollback
boundary.

## What changed

- Reserve an acceptance sequence for user prompts and elicitation responses
  when retained thread context is enabled.
- Persist that sequence with user-message metadata and verified answers, and
  use it when ordering, bounding, replaying, and rolling back retained context.
- Keep events without acceptance metadata compatible with legacy recording
  order.

## Testing

- Cover delayed queued-input recording, rejected prompts, checkpoint replay,
  compaction, rollback migration, and legacy retained-context behavior.

felixxia-oai 80d7ca34bc Retain user instructions in guardian thread context (#42762)
## Why

Guardian review needs the original user instructions alongside verified answers, even after compaction, resume, or rollback. A summarized or legacy checkpoint cannot establish a complete instruction history.

## What changed

- Capture text user messages in retained context when `guardian_thread_context` is enabled, preserving their message identity through compaction and replay.
- Keep retained instructions and verified answers in arrival order, with independent size and completeness tracking for each family.
- Roll back retained evidence at the exact user-message boundary, including steers that share a turn ID, and apply the same semantics during rollout migration.
- Treat checkpoints without retained user messages as incomplete while preserving their verified answers.

## Testing

- Cover capture, compaction, resume, rollback, child forks, legacy checkpoints, storage bounds, and rollout migration.

jif cc4b8bdeb8 Propagate response tickets to Guardian reviews (#42758)
## What changed

- Request and parse server-issued Guardian tickets for eligible Codex backend responses.
- Scope each ticket to the response that produced a Guardian review or classifier request, including HTTP and WebSocket retries, without adding it to model-visible or persisted context.
- Validate ticket shape, reserve its metadata keys, redact it from debug and request-body logging, and attach it only at the Guardian transport boundary.

## Testing

- Cover ticket parsing, endpoint and authentication routing, retry scoping, classifier retries, and redaction for compressed and uncompressed requests.

jif 8e85265c39 Handle pending network reviews after process completion (#42746)
## Why

A remote process can finish while a network policy review is still pending. Normal process cleanup should withdraw that review without turning the completed command into a review failure or losing its output.

## What changed

- Record whether a network policy request was withdrawn because the process finished, was cancelled, lost its executor connection, or timed out.
- Treat normal process completion as cleanup while retaining fail-closed behavior for other cancellation causes.
- Preserve explicit network denials before policy persistence so cleanup cannot replace the reported call outcome.

## Testing

Add an integration test that completes a remote process during a pending network review and verifies that the command reports its successful exit and output without approving the withdrawn request.

jif 4e48cd02da Honor model-provided Guardian review policies (#42744)
## What changed

- Add optional per-model Guardian modes for computer use, shell, code mode,
  file changes, MCP, network, and permission requests.
- Apply disabled, synchronous, or adaptive review by action category while
  preserving legacy configuration when model policy is absent.
- Bind cached risk scores to the active model policy, thread settings, and
  environment selections so outdated scores cannot approve later actions.
- Keep unknown review modes on the synchronous path and ignore unknown policy
  fields for forward compatibility.

## Testing

- Cover policy serialization, legacy fallback, scoped tool classification,
  disabled categories, and score invalidation after policy changes.

felixxia-oai ad8ee16a5f Require Guardian review for incompatible compaction checkpoints (#42588)
## Why

Guardian can reuse an opaque parent compaction only when the checkpoint's
recorded producer hash matches the scoring model. Missing or incompatible
provenance must not allow an asynchronous score or cached approval to omit
compacted context.

## What changed

- Record the producing model's compatibility hash on compaction history items
  and expose the latest checkpoint hash through conversation snapshots.
- In thread-owned context mode, fail closed and require synchronous review when
  checkpoint reuse is enabled but the latest checkpoint is incompatible or has
  unknown provenance.
- Reject incompatible checkpoints in the sampler while preserving the legacy
  context behavior.

## Testing

Add coverage for local, remote, resumed, compacted, and rolled-back histories,
including matching, mismatched, missing, and empty compatibility hashes.

felixxia-oai 1d74c3ba1e Persist verified user answers in Guardian thread context (#42579)
## Why

Guardian authorization reviews need host-verified `request_user_input` answers to
remain aligned with thread history across compaction, resume, and rollback.

## What changed

- Record verified question-and-answer pairs in retained thread context when
  `GuardianThreadContext` is enabled, and source both local and delegated Guardian
  review evidence from that context.
- Preserve complete answer records within the evidence budget. Mark authorization
  context incomplete when records are unavailable or oversized, and defer cached
  fast approvals in that case.
- Keep the existing runtime-only answer path for threads that do not enable the
  thread-owned context.

## Testing

- Cover answer retention through compaction and resume, removal after rollback,
  source-call eviction, oversized answers, delegated review evidence, and legacy
  behavior.

iceweasel-oai 7a7c188682 Preserve target-native paths in command approvals (#42577)
## What changed

- Pass the selected executor's `PathUri` through user command approval requests instead of converting the working directory to a host-native path.
- Make native-path permission helpers explicitly local and require executor-aware permission transforms to receive a `FileSystemSandboxPolicyContext`.
- Cover approved remote commands to verify that the approval request reports the selected remote working directory and execution resumes after approval.

Matthew Zeng 460b63e5f4 Honor explicit plugin mentions during MCP startup (#42406)
## Why

Selected plugin MCP servers may be skipped after the optional startup grace
period. When a user explicitly mentions a plugin or MCP server, the turn should
continue waiting so the requested tools are available to the model.

## What changed

- Track explicitly mentioned plugin IDs and MCP servers across later samples,
  steered input, and same-turn restarts.
- Require matching selected-plugin MCP servers to finish startup before
  capturing the tool catalog, while leaving unmentioned servers optional.
- Match `plugin://` identities independently of display names and ignore
  targeting query parameters such as `app` and `browserFamily`.

## Testing

Added coverage for linked and structured plugin mentions, direct and batched
capability discovery, delayed environment attachment, steering, and same-turn
restarts.

- For eligible ChatGPT Plus, Pro, and Pro Lite sessions using the Codex backend, enable token-budget context, history notes, and the `new_context` tool when experimental context management is configured.
- Keep the feature disabled for custom providers, provider credentials, non-Codex endpoints, and temporary structured threads.

## Testing

- Cover subscription eligibility, backend restrictions, configuration resolution, token-budget guidance, and temporary-thread overrides.

dhruvgupta-oai 5037919777 Add Luna Reserve usage fallback to the TUI (#42372)
## Why

When ordinary included usage is exhausted, eligible users need a way to keep working with the backend-provided Luna Reserve quota and return to their previous model once ordinary usage recovers.

## What changed

- Automatically switch eligible TUI tasks to Luna Reserve after an authoritative account usage read, preserving the prior model and reasoning effort per task.
- Restrict model selection while on Reserve to its supported reasoning levels, keep queued turns on the accepted model, and restore the saved model after a fresh read confirms recovery.
- Surface Reserve usage in the composer and `/status`, and expose `normalModelSlug` in app-server rate-limit snapshots so clients can use the associated model's display metadata without changing the request model.
- Poll account limits more frequently near exhaustion and retain compatibility with app servers that only accept the legacy null request parameters.

## Testing

- Added coverage for Reserve entry, queued-turn handling, task reconstruction, recovery authorization, account changes, model selection, usage rendering, and banner dismissal.

felixxia-oai 0d502a4230 Support durable reasoning configuration updates (#42328)
## Why

Reasoning configuration changes need to retain their position and trusted provenance when model history is persisted and replayed. Client-injected history must not be able to forge these controls.

## What changed

- Add a typed `configuration_update` response item carrying reasoning effort, including custom model-defined values.
- Persist harness-authored updates with provenance and preserve them across history reconstruction, thread resume, raw response notifications, and agent forks.
- Exclude untrusted configuration updates from model history, strip client-supplied provenance metadata, and reject configuration updates supplied as turn input.
- Export the new item through the JSON and TypeScript app-server schemas and classify it in telemetry and persistence metrics.

## Testing

- Cover serialization, provenance persistence, history filtering and rollback, resume reconstruction, and injection attempts before and after restart.

iceweasel-oai eb078b4f44 Preserve target-native cwd in permission approval requests (#42314)
## Why

Permission requests can originate in an environment whose path convention differs from the Codex host. Requiring the request working directory to be host-native prevents those requests from reaching interactive approval.

## What changed

- Carry the request `cwd` as a `LegacyAppPathString` through core events and the app-server protocol so the target environment's native representation is preserved.
- Convert the preserved value back to a `PathUri` when materializing permission grants.
- Regenerate the JSON and TypeScript protocol schemas for the updated `cwd` type.

## Testing

- Exercise the app-server permission request round trip with a target-native working directory across host path conventions.
- Verify remote permission requests retain their environment working directory and granted access still unblocks later execution.

felixxia-oai 5971d42847 Preserve verified answers across history compaction (#42293)
## Why

Compaction replaces the model history window, but host-verified user answers may
still be needed for the rest of the owning thread.

## What changed

- Add bounded, model-invisible retained context for verified
  `request_user_input` answers.
- Persist retained context in rollout events and compaction checkpoints, and
  restore it when a thread resumes.
- Remove answers when their source turns are rolled back, and prevent
  parent-local answers from being inherited by child forks.

## Testing

Add lifecycle coverage for deduplication and size limits, compaction and resume,
rollback, rollout migration, and child forks.

rka-oai 2c79ee6dac Add structured asynchronous user input requests (#42178)
## What changed

- Replace `send_user_message_async` with `request_user_input_async`, accepting one or more questions with optional suggested answers while allowing the turn to continue.
- Attach structured question metadata to asynchronous agent messages while retaining readable fallback text, and preserve it through app-server events, thread history, and generated schemas.
- Continue enabling the new tool for model catalogs that advertise either the old or new tool name.

## Testing

- Cover tool registration, question validation, emitted items, continued turn execution, history preservation, and backwards-compatible deserialization.

jif e576993911 Skip Guardian reviews in Full Access (#42147)
## Why

Full Access already combines `approvalPolicy: "never"` with unrestricted
permissions, so confirmation-only actions do not require a model review.

## What changed

- Detect Full Access consistently across the thread and every selected
  environment. Pending, failed, or restricted environments are not treated as
  Full Access.
- Approve confirmation-only Guardian and MCP requests without synchronous
  review, sampler prewarming, or background scoring. Cancellation, explicit
  denials, and forms that require user input keep their existing behavior.
- Re-evaluate the active permission state on each turn so an existing thread
  can enter or leave Full Access safely.

## Testing

Added coverage for switching approval modes, strict sensitive MCP
confirmations, failed and pending environments, and suppression of Guardian
requests and background-scoring connections.

iceweasel-oai cd8bd62c6e Resolve permission requests in the executor context (#42146)
## Why

`request_permissions` paths and grants need to be evaluated against the selected executor environment, including its path convention, home directory, workspace roots, and temporary directories.

## What changed

- Resolve relative and home-relative permission paths using the executor context, reject mismatched path conventions and lossy paths, and support legacy `read` and `write` path lists.
- Move grant intersection into core so requested and granted permissions use the originating environment's sandbox context. Preserve deny entries conservatively when a special path cannot be resolved.
- Keep the full originating environment with pending permission requests so delayed responses are normalized against the same context.

## Testing

- Cover POSIX, Windows, UNC, relative, and home-relative path resolution and invalid path contexts.
- Verify end-to-end app-server grants are limited to the requested workspace scope and unresolved temporary-directory denies are preserved.

- Add `guardian_v2_enabled` to turn analytics, accounting for review scope
  and model requirements.

## Testing

- Extend the Guardian V2 app-server coverage to verify event payloads,

jif 612e6491d5 Prewarm shell snapshots for eligible turns (#42137)
## Why

Shell Snapshot V2 previously captured the login-shell environment lazily when a
command started, adding that work to the command path.

## What changed

- Start one asynchronous snapshot capture after turn hooks accept the turn, so
  eligible local `exec_command` calls can reuse it without blocking the model.
- Use the turn's resolved tools, permissions, sandbox, environment, and shell
  configuration, and skip prewarming for unsupported or network-managed cases.
- Cancel outstanding prewarming during shutdown. Keep failed speculative
  captures retryable by real commands without consuming their retry budget.

## Testing

Added coverage for non-blocking capture and reuse, failure recovery, sandbox and
permission isolation, shutdown cancellation, hook-stopped turns, eligibility
gates, and concurrent capture retries.

Charlie Marsh 8436b749a4 Bound Git root discovery for metadata enrichment (#42132)
## Why

Git root discovery is optional metadata work, but filesystem probes can block. They should not exhaust Tokio's blocking pool, delay runtime shutdown, or prevent later turns from observing repository changes.

## What changed

- Add a shared `GitRootDiscovery` service that coalesces concurrent lookups for the same working directory and limits probes across directories.
- Run probes on detached threads, retain in-flight work across caller cancellation, and discard completed results instead of caching them.
- Use the service for turn and memory metadata enrichment, abort unused turn enrichment when its state is dropped, and limit memory metadata waits to one second.

## Testing

Add coverage for probe sharing, capacity limits, cancellation, fresh discovery, runtime shutdown, memory timeouts, and repositories restored after startup prewarming.

- Keep legacy refresh behavior in builds where coordination is unavailable and emit a warning when coordinated mode is selected.

## What changed

- Store the bounded, model-invisible Guardian transcript alongside compacted rollout history and restore it from the newest surviving checkpoint during replay.
- Trim Guardian history at rollback boundaries, clearing it when the boundary has already been evicted.
- Preserve the checkpoint for user-initiated forks, but remove it when spawning a subagent so parent review evidence is not inherited.
- Keep the new rollout field optional for compatibility with existing compacted records and legacy readers.

## Testing

## Why

Realtime history should be recorded consistently for every Core host, including
when no app-server event listener is attached.

## What changed

- Move transcript segmentation, session boundaries, and backing-agent artifact
  promotion into Core for paginated threads.
- Persist canonical realtime items through the thread store in event order and
  emit dedicated history lifecycle events for hosts to present.
- Translate those Core events into the existing app-server realtime item
  notifications without app-server persisting the items a second time.

## Testing

- Cover Core-only persistence across repeated sessions, ephemeral sessions,
  accepted and rejected steering, typed input ordering, and artifact promotion.
- Verify app-server notifications correspond to the persisted timeline.

- Add `auto_review.node_repl_policy` to model messages for `node_repl` and `cua_repl` reviews.
- Use the reviewer model's configured policy, falling back to the bundled policy when the field is absent and skipping injection when it is explicitly empty.
- Include the effective policy in Guardian session reuse checks and reject unsafe parent-model fallback transitions that would change it.

## Testing

- Cover catalog, bundled, and explicitly empty policies across Node and CUA review paths.
- Verify that policy changes invalidate cached reviewer sessions and incompatible fallback transitions.

- Add durable `TokenUsageRecord` rollout items with response, turn, thread, session, and root-turn attribution.
- Restore accumulated usage on resume and snapshot the latest record plus the compaction response ID in compaction checkpoints.
- Preserve root-turn lineage in persisted turn context, while ensuring forked child threads start with their own usage totals.

## Testing

- Cover usage accumulation across multiple responses and resumed turns.
- Cover local and remote compaction checkpoints, invalid remote compaction output, rollout reconstruction, and fork isolation.

Bryan Ashley f88ff940c0 Load bounded context after empty wake turns (#41901)
## Why

Paginated threads can accumulate wake turns with no user-message boundary. The
reverse context scan could not use those turns as a bounded replay cutoff, even
when a compaction and its resume state provided everything needed to reconstruct
the latest model context.

## What changed

Treat a full world-state snapshot that survives the latest compaction as a
durable baseline when it is paired with a compatible turn context. This lets the
scan stop at empty wake turns while still scanning further back for patches,
snapshots before compaction, or missing and mismatched turn contexts.

## Testing

Add coverage for repeated empty wake turns and verify that bounded replay
matches full rollout reconstruction across successive compaction windows.

Benjamin Carlsson 9d19c7426e Box the session startup future at its API boundary (#41853)
## What changed

- Make `Session::spawn` return a `BoxFuture` while preserving lazy session
  initialization.
- Prevent the startup wrapper from being inlined so callers do not expose its
  concrete future.
- Await the returned future directly at session creation call sites.

jif 1c1e17782a Preserve Guardian review evidence across compaction (#41846)
## Why

Context compaction can replace original conversation items that Guardian still needs to review approval-sensitive actions.

## What changed

- Retain a bounded, chronological review history independently of the model's compacted history.
- Keep separate limits for user messages and other transcript items so tool traffic cannot evict user instructions.
- Use the retained evidence for synchronous and asynchronous Guardian transcripts, while resetting it after rollback or history reconstruction.

## Testing

- Cover retention through compaction and eviction, reset behavior after rollback, independent size limits, and asynchronous transcript construction.

pmccrary-oai d58d0e5841 Allow models to enable token budgeting by default (#41803)
## What changed

- Add model metadata flags for enabling token budgeting and its history-notes extension.
- Apply those activation defaults once at thread startup when the user has not explicitly configured token budgeting, while respecting managed feature requirements.
- Continue resolving model-owned prompts for the active model so model switches can use their own token-budget guidance.

## Testing

- Update the token-budget integration test to verify that model metadata activates the feature without manual configuration.

rka-oai a9519cbcdd Make the update_plan tool opt-in (#41744)
## What changed

- Default `tools.update_plan.enabled` to `false`; users can explicitly enable it to expose `update_plan`.
- Remove bundled `update_plan` guidance from model, collaboration-mode, multi-agent, compaction, prewarm, and goal-continuation prompts when the tool is disabled.
- Preserve custom base instructions, model catalog instructions, collaboration policies, and user goal text even when they mention planning or `update_plan`.

## Testing

- Cover default and explicitly enabled tool registration, prompt consistency across request paths, and preservation of custom instructions.

pmccrary-oai b7cd519c76 Mark history ingestion requests in turn metadata (#41743)
## What changed

- Set `history_ingest_requested` to `true` in Responses turn metadata when the
  history-notes token-budget extension is enabled.
- Reserve the metadata key so caller-provided metadata cannot override the
  core-owned value, and omit it when the extension is disabled.

jif 0a12b855a0 Preserve Guardian authorization across history compaction (#41660)
## Why

Compaction and host-injected context can rewrite the model-visible conversation
without changing what the user authorized. Treating those updates as authorization
changes prevents Guardian from reusing an otherwise valid review.

## What changed

- Track a host-owned user-message revision separately from the conversation history
  generation.
- Advance the revision for genuine user messages and history resets, while preserving
  it across compaction and internal context injection.
- Use message content-kind metadata to distinguish host context from user input,
  conservatively treating unknown or incomplete metadata as user authorization.

## Testing

Added coverage that cached Guardian authorization survives compaction and internal
context, but is invalidated by user input and rollback.

## What changed

- Cover the default, explicitly enabled, and explicitly disabled states of
  `tools.update_plan.enabled`.
- Verify prompt tool lists remain consistent across requests, including when
  custom base and developer instructions are configured.
- Explicitly enable `update_plan` in existing fixtures that depend on the tool.

rhan-oai f5636bb733 Restore thread cwd from owned settings snapshots (#41567)
## Why

Resuming a thread without an explicit `cwd` should restore that thread's latest
retained setting. Forked history can contain settings copied from another
thread, while compaction can move the latest setting outside the replay window.

## What changed

- Record the owning thread ID on new settings snapshots and only use snapshots
  owned by the resumed thread when restoring `cwd`. Older snapshots without an
  owner remain readable but do not override the startup `cwd`.
- Checkpoint the current settings after compaction and serialize checkpoints
  with settings updates so the retained history contains an accepted, current
  snapshot.
- Cover resume behavior across compaction, forks, reverts, legacy histories,
  and concurrent settings updates.

Eric Traut 4210c08def Preserve turn lineage across goal continuations (#41562)
## Why

Automatic goal continuations should remain attributable to the turn that created the goal. External input, hook context, or goal edits can make that attribution ambiguous and must not leave stale lineage metadata behind.

## What changed

- Carry the trusted root and previous parent turn through successive automatic goal continuations.
- Invalidate stored lineage when external context reaches an active turn or when a goal is edited or cleared.
- Preserve lineage for async hook results only when they belong to the receiving turn.

## Testing

- Cover goal continuations across intervening user turns and external objective edits.
- Cover active, buffered, and externally injected hook or response context.

Tamir Duberstein 6478a751fd Organize bundled Rust resources under asset directories (#41477)
## Why

The `core` and `tui` Bazel targets treated nearly their entire crate trees as
compile-time data, mixing embedded runtime resources with source files and test
fixtures.

## What changed

- Move embedded resources for `core` and `tui` into dedicated `assets/`
  directories and update their `include_str!` paths.
- Restrict Bazel compile data to explicit asset and frame directories.
- Move test-only prompts into `tests/fixtures`, resolve the core prompt through
  `find_resource!`, and reuse the integration-test file glob when assembling
  Bazel test data.

## What changed

- Defer legacy sandbox policy projection until a working-directory change may require rebinding project-root writes.
- Keep client name and version updates from resolving filesystem paths or altering the existing permission snapshot.

## Testing

- Add regression coverage for updating client metadata with a managed, restricted filesystem policy that includes both a writable path and a nested denied path.

rhan-oai 3c062df036 Source async user message descriptions from the model catalog (#41461)
## What changed

- Add model message metadata for built-in tool descriptions.
- Use the active step model's catalog description for `send_user_message_async`, including after a mid-turn model change.
- Fall back to the built-in description when catalog metadata is absent, while preserving an explicitly empty description.

## Testing

- Cover catalog serialization, fallback and empty-value behavior, and model changes within a turn.

rhan-oai 03861e69ef Source proactive multi-agent instructions from the model catalog (#41457)
## What changed

- Add an optional `proactive` multi-agent mode message to model metadata.
- Use the catalog's proactive message for `Ultra` reasoning when no general mode hint is configured. A missing value falls back to the built-in proactive instructions, while an empty value suppresses the mode message.
- Keep explicit mode behavior for other reasoning efforts and refresh the applicable catalog message when the model changes.

## Testing

- Cover proactive overrides, built-in fallback, empty-value suppression, mode-hint precedence, non-`Ultra` behavior, and model switches.

victor-openai eec4a23cb1 Support openai/elicitation form requests (#41447)
## What changed

- Advertise `openai/elicitation` form support when the client declares an
  object-valued `form` capability, without deriving it from the legacy
  `openai/form` capability.
- Handle `openai/elicitation/create` requests in `form` mode and forward their
  metadata and opaque schema through app-server as `openaiForm`, preserving
  `x-openai-*` annotations.
- Keep legacy form handling independent and have the TUI automatically decline
  the new form requests it cannot render.

## Testing

- Add an app-server round-trip test for capability negotiation, request
  forwarding, and accepted responses.
- Extend MCP capability filtering coverage for `openai/elicitation.form`.

Krish Chainani 0d22692962 Retain the last selected step context for each turn (#41429)
## What changed

- Store the most recently captured execution `StepContext` in the active turn state.
- Keep speculative model-fallback captures from replacing that context, and update it only when the fallback is selected for remote compaction.
- Preserve the retained context when a turn completes or is interrupted.

## Testing

- Add coverage for completed and interrupted turns, successful primary compaction, fallback compaction, and interruption while a fallback is running.

jif f9cdc90c2c Preserve context baselines across nested agent forks (#41424)
## What changed

- Treat a surviving full world-state snapshot as a context baseline when a fork removes the associated user message.
- Restore the previous turn settings and reference context from that baseline, without treating the segment as a user turn for rollback.
- Ignore partial snapshots and full snapshots superseded by compaction.

## Testing

- Cover resumed rollout reconstruction with removed task messages, partial snapshots, and compaction.
- Verify nested agents inherit developer instructions and environment context exactly once across history modes and compacted histories.

## What changed

- Add a positive `output_token_limit` setting to each entry under an MCP server's `tools` configuration.
- Apply the most restrictive limit when plugin and user policies overlap, while keeping approval policy independent.
- Carry the effective MCP output budget in conversation history so tool output, post-tool hook responses, and resumed sessions use the same truncation limit.

## Testing

- Cover configuration parsing, serialization, schema validation, and plugin policy merging.
- Cover MCP output below and above the configured limit, post-tool hook responses, and session resume.

## What changed

- Add an optional `timeoutMs` parameter to `thread/shellCommand` and propagate it to user shell execution.
- Preserve the one-hour default when the parameter is omitted or `null`, allow longer deadlines, and treat `0` as an immediate timeout.
- Reject negative or otherwise invalid values before execution. Timing out an auxiliary shell command leaves its active turn running.

## Testing

- Cover default, extended, immediate, invalid, standalone, active-turn, and interruption behavior.
