## Why
Curated plugin capabilities need to follow the active authentication mode, including after an account switch and when the configured model provider differs from the authentication source.
## What changed
- Select the ChatGPT, remote, or API curated marketplace from the current authentication mode, with an API marketplace fallback for ambient Amazon Bedrock credentials.
- Apply that selection consistently to plugin loading, hooks, skills, installed-plugin conflict filtering, marketplace listing, and `codex mcp` discovery.
- Start the local curated repository sync when an account change makes the remote catalog unavailable, and refresh existing thread MCP runtimes when the effective plugin cache changes.
## Testing
Added coverage for account switches, ChatGPT-authenticated Bedrock sessions, API-key MCP discovery, curated marketplace filtering, hook and skill routing, and existing-thread MCP refreshes.

## What changed
- Clamp the initial `exec_command` yield time to at least 10 seconds on Windows.
- Update the tool description and unit coverage for the new effective range.
- Allow the Windows Ctrl-C integration test up to 20 seconds to complete.
GitOrigin-RevId: 65d4d1c9a89dc9979e10d3e565af61c9f632c058
Initialize the Windows-only `ProcessDriver::tty` field to `false` when
constructing the streaming output test harness.
GitOrigin-RevId: 95683779072cba31664d059750b81ee0d9c17664
## What changed
- Add a character n-gram shadow selector that combines skill descriptions with host interface metadata and tool dependency names and descriptions.
- Bound routing fields, dependency records, and candidate counts before ranking.
- Exclude explicitly selected skills from shadow candidates and only record invocations for skills eligible for the experiment.
## Testing
- Add unit coverage for host interface metadata, connector dependencies, baseline description matches, and long routing metadata.
GitOrigin-RevId: 36ef0cb4a68601f2d9d41c3344c88f7927c32bf4
## What changed
- Insert the `host_skills` world-state section before the permissions section
when permissions are present.
- Verify that skill metadata appears before `<permissions instructions>` in the
rendered developer message.
GitOrigin-RevId: e9fc62f498c384e841fc34ef679850557645f989
## Why
`features.multi_agent_v2` can be represented as either a legacy boolean toggle
or a table with an `enabled` field and nested settings. Layering or editing
configs that mix these forms could replace one form with the other and discard
the enabled state or nested settings.
## What changed
- Normalize boolean toggles to the table's `enabled` field when merging config
layers, applying CLI overrides, and editing user or profile config.
- Preserve nested multi-agent settings when toggling the feature, while keeping
ordinary replacement semantics for unrelated paths.
- Attribute normalized `enabled` values to the layer that supplied the boolean
toggle so config write results report overrides correctly.
## Testing
Added coverage for layered config, CLI overrides, config edits, app-server
writes, and origin metadata using both root and profile feature paths.
GitOrigin-RevId: 38b248c949b9ea5d6340a73d754f91c1834ac486
## Why
Windows non-TTY exec sessions reported interrupts as unsupported, so sending
Ctrl-C through `write_stdin` did not stop the running process.
## What changed
- Route interrupt requests for Windows non-TTY processes through their existing
termination callback, including pipe-backed processes.
- Track whether driver-backed Windows sessions use a TTY so PTY interrupts keep
their existing behavior.
- Consume the terminator after a successful interrupt to avoid invoking it again
when the process handle is dropped.
## Testing
Added coverage for local and remote exec-server sessions, unified exec, pipe
fallbacks, and legacy Windows sandbox processes.
GitOrigin-RevId: 34504d01f091ef57bb961e98ad5a8d9f1acee4ee
## Testing
- Verify full, compacted, and bounded history forks preserve developer messages while removing stale parent usage hints.
- Add an app-server regression test that cold-resumes a root thread and confirms a roleless worker retains inherited developer instructions when lazily reloaded for follow-up work.
GitOrigin-RevId: 40e454a2a2b721ea645cbc607b17a3ae6b617bd9
## What changed
- Forward remote managed-network policy requests to the controller-side decider when Guardian review is enabled.
- Bound callbacks using the configured permission-hook and Guardian review timeouts, restore trusted execution attribution, and recheck live baseline policy before requesting a decision.
- Cancel pending decisions when the process or execution scope ends, and propagate EOF across the sandbox proxy bridge with half-closes.
## Testing
- Cover callback enablement, strict allowlist behavior, live policy updates, trusted attribution, and execution-scope cancellation.
GitOrigin-RevId: 83b47657c8c4546dfe98eec8b272833e96a46b7e
## Why
Refreshing the terminal palette on a focus event can block the input loop and
discard keystrokes entered while focus is returning.
## What changed
- Keep the palette cached by the startup probe when handling `FocusGained`.
- Continue updating focus state and requesting a redraw without issuing new
foreground or background color queries.
## Testing
- Verify a queued key is delivered after `FocusGained`.
- Exercise focus regain in a pseudo-terminal with immediate and delayed input,
and verify it emits no additional palette queries.
GitOrigin-RevId: 16e26f81c1343d01f6d0baeff3f204bcc91dd6f3
## What changed
- Skip threads whose rollout files cannot be found while continuing through
database pages until the requested number of valid threads is collected.
- Retain the skipped threads and their rollout paths in the state database
instead of deleting their metadata during listing.
## Testing
- Update the state-backed listing test to verify that a missing rollout path
does not consume a page slot or remove the stored thread metadata.
GitOrigin-RevId: 51c03a78434b0aeeb5a2dc685b97243b6ad958bf
## What changed
- Guard `OtelProvider::shutdown` so exporters shut down at most once, including when an explicit shutdown is followed by `Drop`.
- Let tracer provider shutdown handle flushing without a separate `force_flush` call.
- Add regression tests for explicit shutdown and drop-only shutdown.
GitOrigin-RevId: f3c8769146ee57102477eb9ee7fd948f688efb79
## Why
Cursor session messages can place `<cursor_commands>` and `<timestamp>` context
before the actual `<user_query>`. Treating both external session formats with one
parser left that context in the imported message and generated title.
## What changed
- Route detected sessions through format-specific Claude and Cursor parsers.
- Strip recognized Cursor context wrappers when extracting a trailing
`<user_query>`, while preserving messages with unknown leading context.
- Keep shared content-block, tool-call, and timestamp parsing in a common module.
## Testing
Add parser coverage for wrapped Cursor queries, unknown context, working-directory
precedence, Claude metadata, content hashing, and shared tool annotations.
GitOrigin-RevId: b49328d46ab4937e3c599588a3d3081e8ab798cd
## What changed
Set `excludeTurns` on `codex exec` thread resume requests so the app server
does not return reconstructed turns or replay their restored token usage.
## Testing
Extend the `resume --last` integration test to verify that resuming a session
emits only the live turn's `thread/tokenUsage/updated` event.
GitOrigin-RevId: 3347071142e7453ea9e3ac9ac292aa5384d98430
## What changed
- Add token-budget settings to model catalog messages and apply them when the
feature is enabled without explicit token-budget configuration.
- Keep explicit user settings authoritative, reject invalid catalog defaults,
and preserve resolved defaults in exported config locks.
- Manage context-window guidance through world state so it updates once when
the active model changes while retaining prior conversation history.
## Testing
- Cover catalog defaults, explicit overrides, disabled features, invalid
values, config-lock replay, and model switching.
GitOrigin-RevId: 54544fefaa14b09f5ef5bad9967a13c52b87b0fe
## Why
Empty rendered skill catalogs skipped catalog telemetry instead of reporting
zero-valued counts.
## What changed
- Record a default render report when thread, turn-input, or executor catalog
rendering produces no fragment.
- Record zero-valued host world-state metrics when skill instructions are
enabled but no host skills are available.
- Preserve the `catalog_surface` tag so empty host and executor catalogs remain
distinguishable.
## Testing
Add coverage for empty catalog rendering and mixed nonempty-executor,
empty-host world state.
GitOrigin-RevId: f68d65806703c0ded1ece1e5ae1ffaf6d6045126
## What changed
- Add an optional `ExtensionMetrics` capability to thread, turn-input, and world-state contributors, backed by session telemetry in the host.
- Record skill counts, omissions, and truncated description characters for extension-rendered catalogs, tagged by the catalog surface.
- Preserve host session attribution on extension metrics, including the effective model for each turn, and prevent extension tags from overriding host metadata.
- Avoid duplicate host-catalog samples by recording world-state metrics only when the section is published or changes.
## Testing
- Cover metric values and surface tags, session metadata preservation, turn-level model changes, and host world-state publication behavior.
GitOrigin-RevId: 9059e521943a8f81df25a38b03692eddbc1d990d
## What changed
Update the v2 `wait_agent` timeout description to recommend minute-scale waits
that avoid busy polling, matching the existing v1 guidance. Extend the tool-spec
test to cover the updated description.
GitOrigin-RevId: 615dfbd7cb5038013131ae8cb959d35e07c6f48a
## Why
Cached MCP definitions can be supplied to inference without waiting for the
server to finish initializing.
## What changed
- Publish cached tools while startup is still in progress, clearing their
potentially stale read-only hint.
- Wait for the selected server to start before executing a tool call, then
prepare the call against the refreshed live binding.
- Keep cached tools visible in a binding even when no live client is available,
while rejecting attempts to prepare those calls.
## Testing
- Cover cached-tool visibility before startup and replacement with live tool
metadata afterward.
- Verify cached definitions reach inference before MCP initialization and that
calls unavailable in the live catalog return the expected model-visible
error.
GitOrigin-RevId: 3aae8f474c344ccdc5e08fe321bbad21d85bffd1
## What changed
- Add the stable, default-enabled `in_app_updates` requirements-only feature.
- Allow administrators to disable in-app updates through `[features]` in `requirements.toml`.
- Expose the policy through `configRequirements/read` and include it in the config schema.
## Testing
- Verify that in-app updates are enabled by default and disabled by the managed requirement.
- Verify that `configRequirements/read` returns the configured policy.
GitOrigin-RevId: e9c7074b516fe58385fdf7dc8420c0109c0c3df6
## What changed
- Add model and personality sections to the persisted world-state snapshot.
- Generate model-switch and personality instructions through world-state diffs, including when prior state must be inferred during replay.
- Keep those instruction fragments in standalone developer messages instead of merging them with adjacent context updates.
## Testing
- Cover initial, unchanged, and changed model and personality states.
- Verify that model changes are recorded in rollout world-state items.
GitOrigin-RevId: 497e29cf38cac08e992e546df900f6f8b01120f9
## What changed
Only collect buffered requests from inactive threads whose event store reports
pending user input or approval. This keeps unrelated requests from being
considered when pending interactions are surfaced after leaving a side
conversation.
## Testing
Extend the side-conversation routing test with an unrelated dynamic tool request
and verify that only the pending subagent approval is selected.
GitOrigin-RevId: 388968277bde34bedc43187c1d1746d76166131e
## Why
When rebuilding a thread from rollout events, errors embedded in turn completion
events were ignored. Failed retries could therefore be restored as completed
turns, causing warnings such as model-overload errors to disappear from the TUI
transcript.
## What changed
- Mark turns with terminal completion errors as failed and retain their message
and structured error information.
- Apply late completion errors to their matching historical turn without
interrupting the active turn.
## Testing
Added history-builder coverage for current and late completion errors, plus a
TUI replay snapshot covering repeated overload failures.
GitOrigin-RevId: 5c474baa0fd5c73368b444d79fb850cbd4c8023a
## Why
Detached processor work can retain outgoing message senders, so waiting for
channel closure can keep the in-process app-server's outbound router alive
during shutdown.
## What changed
Add an explicit shutdown signal for the outbound router and prioritize it over
pending outgoing messages. Send that signal after processor tasks are stopped
so runtime shutdown no longer depends on every sender being dropped.
## Testing
Add a paused-time test that verifies the router exits and closes its channel
even when an outgoing sender is still retained.
GitOrigin-RevId: a8f88d88a0950f50339b1c56909fedb781f178d4
## What changed
- Set the Rust recursion limit to 256 for both the MCP server library and binary crates.
- Populate `started_at_ms` in the thread-fork test's completed-item fixture.
GitOrigin-RevId: b25eeaeecaf94265fe3be8f23cb3c395595afc2a
## What changed
- Exclude `SkillScope::System` roots from watcher registration because generated
system skills are installed before the watcher starts.
- Ignore events under the system skill cache that arrive through the recursively
watched legacy user-skills root, avoiding unnecessary cache clears and
`SkillsChanged` notifications.
GitOrigin-RevId: ce8ba28ba873372b638950b676e4d09172a5c688
## What changed
- Stack action descriptions below their labels when the keymap action menu is too narrow for a readable description column.
- Keep descriptions column-aligned at wider terminal widths.
- Show a dash instead of a number beside the disabled remove-binding action.
## Testing
- Add snapshot coverage for the action menu at 48, 64, and 96 columns.
GitOrigin-RevId: 25b97fd2d8764563e0a0c36d436711f2429093c4
## What changed
- Restart file search whenever a unified mention popup opens so restored or repeated queries receive results instead of inheriting stale search state.
- Cache the popup's filtered rows and refresh them when the query, file matches, search mode, skills, or plugins change.
## Testing
- Add regression tests for bare, reopened, and restored unified mention searches.
GitOrigin-RevId: 9d38438fade01a0552e03cb05e023ee64af60a4c
## Why
The Code Mode tool-name mapping is unbounded and can make HTTP and WebSocket
headers grow without limit.
## What changed
Omit `code_mode_tool_names` from the direct `x-codex-turn-metadata`
compatibility header while retaining it in the canonical
`client_metadata["x-codex-turn-metadata"]` payload.
GitOrigin-RevId: 494a30b6846e32ab44eb79b08dfec63360f563a7
## What changed
- Add an optional `started_at_ms` field to `ItemCompletedEvent`, retaining
compatibility with older persisted events that lack it.
- Track the first start timestamp for each in-flight item and attach it when
emitting and persisting the completion event. If no start was recorded, use
the completion timestamp as a fallback.
- Emit a complete start/completion lifecycle for subagent activity items.
## Testing
- Cover concurrent item timing, repeated starts, turn-boundary cleanup, the
missing-start fallback, subagent activity, and persisted web-search events.
GitOrigin-RevId: e7cec9c4f1ef6ba67f287e81fb4d7d856fcf87a7
## What changed
- Add client-side handling for exec-server network policy requests, including request validation, per-process decision routing, and allow, deny, or ask responses.
- Bound concurrent callbacks and fail closed when requests are invalid, exceed capacity, time out, or outlive their process session.
- Replace the callback opt-in flag with a launch-level `policyDecisionTimeoutMs` value and include transport overhead in the executor timeout.
- Preserve callback admission limits across connection recovery and clean up policy state when process startup is abandoned or a session ends.
## Testing
- Cover decision forwarding, invalid and excess requests, cancellation during process cleanup, abandoned starts, timeout propagation, and launch-config serialization.
GitOrigin-RevId: 6ee2a0139e0f8170cf1a5cdd646bd811b7d3c1f6
## What changed
- Leave plugin MCP servers unchanged when every plugin requirement omits
`mcp_servers`.
- Continue treating an explicitly empty `mcp_servers` allowlist as deny-all.
## Testing
Added coverage for both absent and explicitly empty plugin MCP allowlists.
GitOrigin-RevId: 80bb9aa6bbd779d669c573f63681dc46019b668c
## What changed
- Preserve the current tracing span and subscriber when lazy remote environment
startup runs in a background task.
- Add spans for the remote connection, environment registry, Noise, and
rendezvous WebSocket stages, including relevant environment and registration
identifiers.
- Propagate the current trace context to environment registry connection and
harness-key validation requests.
GitOrigin-RevId: 0044c3eb94d59c6a6b92752d3d372195be4adb81
## What changed
- Add `code_mode_tool_names` to Responses Lite turn metadata, mapping each normalized code-mode identifier to its structured `ToolName`.
- Reserve the metadata key against client overrides and omit it from metadata exposed to external MCP servers.
- Keep non-Lite requests and the legacy top-level client metadata unchanged.
## Testing
- Cover HTTP and WebSocket Responses Lite requests, including switching from a non-Lite model.
- Verify reserved-key handling and external MCP metadata filtering.
GitOrigin-RevId: b678afba13d57a91e26f5895aa37238fbb4cb276
## What changed
- Scope pending network approvals to a turn and execution while still coalescing duplicate requests within one execution.
- Fail abandoned approval owners closed, cancel denied executions, resolve any waiting requests, and cancel in-flight Guardian reviews when their owner is dropped.
- Serialize session policy updates with approval caches so concurrent allow and deny decisions cannot leave enforcement and cached decisions inconsistent.
- Give user approval requests and permission hooks unique per-execution identifiers.
## Testing
- Cover approval deduplication boundaries, abandoned-owner cleanup, cancellation outcomes, replacement requests, and Guardian cancellation events.
GitOrigin-RevId: 11e184dd1c70294a99581b6ff0d4b6607d9ea1d9
## What changed
- Allow `features.code_mode_host` to use a configuration table with
`disable_in_process_fallback`. When enabled, failure to start the standalone
host is returned as tool output instead of falling back to embedded V8.
- Preserve the existing fallback behavior by default and continue accepting the
boolean feature toggle.
- Limit displayed host paths in spawn errors to 512 bytes while retaining the
executable-bearing suffix and valid UTF-8 boundaries.
## Testing
- Cover boolean and table-based feature configuration, fallback-disabled host
failures, and bounded ASCII and UTF-8 error paths.
GitOrigin-RevId: ab3d014e79054c2f8beef9a658915f01cca197b2
## What changed
- Add `remote_plugin_id` to skill invocation facts and analytics event parameters.
- Propagate the ID for both explicit and implicit plugin skill invocations.
## Testing
- Cover explicit and implicit remote plugin skill invocations with analytics integration tests.
GitOrigin-RevId: 3e1d25b5ff88dcff9c2b6c9fe44bca97e8778221
## What changed
- Carry a plugin's local and remote identities together from plugin loading into
`SkillMetadata`.
- Resolve remote IDs from the installed-plugin snapshot when available, falling
back to persisted install metadata only when no snapshot exists.
- Include plugin identity in skill cache keys so identity changes refresh cached
skill metadata.
## Testing
- Cover snapshot and persisted identity resolution, local marketplace isolation,
cached skill refreshes, and propagation through plugin skill snapshots.
GitOrigin-RevId: aabeeb631a43361fe817358ace7f1ea8ba5db708
## What changed
- Add nullable `canPublishToWorkspace` metadata to plugin share contexts and `plugin/share/save` responses.
- Preserve the remote capability through catalog parsing and app-server responses so clients can decide whether to offer workspace-directory publishing.
- Document that clients should fail closed when the capability is unavailable.
## Testing
- Cover remote catalog parsing, share-save response propagation, and protocol serialization.
GitOrigin-RevId: b0346b3b330169838f800dfdf21dfa5db1a47f4d
## What changed
- Allow `thread/fork` to create an ephemeral fork from paginated history when
`excludeTurns: true` is set, and return an invalid-request error otherwise.
- Preserve the selected history and fork preview without creating a rollout
path or exposing the ephemeral thread through `thread/list`.
## Testing
- Cover full-history and bounded ephemeral forks, active-turn boundaries,
preview selection, model input, and thread listing behavior.
GitOrigin-RevId: 4c0d9739b3310d7d0d7389bec127045ac4f55b44
## Why
MCP authentication checks need to use the same HTTP routing as the MCP
transport so servers reached through configured proxies can be discovered
reliably.
## What changed
- Resolve OAuth discovery and authentication status through each server's
runtime HTTP client for both local and managed environments.
- Keep local discovery capped at five seconds while allowing explicit login
requests to retain their requested timeout.
- Resolve refreshed MCP configuration and its runtime context from the same
snapshot.
## Testing
- Cover OAuth discovery through an environment proxy and macOS system proxy
resolution.
- Cover proxied MCP startup and runtime refresh with updated authorization
headers.
- Verify capped and preserved OAuth discovery timeout policies.
GitOrigin-RevId: 461fb1d4786e547df8b1e6b2215a8ac40438a3aa
## What changed
- Recognize `ent26` in authentication, account protocol, backend rate-limit
payloads, and generated app-server schemas.
- Treat it as an enterprise workspace plan for cloud-config eligibility and
business-style usage-limit guidance.
- Cover token parsing, serialization, backend mapping, plan classification,
cloud-config access, and usage-limit formatting with tests.
GitOrigin-RevId: 537d897c8b1d80bcdb66d0fd402563fbb8c5a277
## Why
Hooks can only consume a transcript path when the thread has a local rollout.
## What changed
- Resolve the local rollout path before materializing the transcript.
- Return no transcript path for non-local thread stores without persisting them.
- Continue materializing lazy local rollouts before passing their path to hooks.
## Testing
Added session and hook tests covering both non-local thread stores and lazy local rollouts.
GitOrigin-RevId: c742984d146f7a3e1048b848198198fc7a64f4de
## Why
`thread/fork` rejected threads using paginated history, so they could not use the same fork workflow as legacy threads.
## What changed
- Create paginated forks by referencing a frozen source-history prefix while persisting only child-owned records in the new rollout.
- Support latest, `lastTurnId`, and `beforeTurnId` boundaries, including inherited lineage, model-context reconstruction, interruption markers, and approval-reviewer inheritance.
- Make paginated reads and occurrence search traverse referenced history while excluding source records added after the fork.
- Coordinate fork preparation with archive and delete operations, and materialize compressed rollouts before they become fork references.
## Testing
Added app-server and thread-store coverage for boundary selection, active turns, inherited reads and search, compressed lineage, and concurrent source lifecycle operations.
GitOrigin-RevId: 66052d69517d7fb97a3b7817ab77a39c5ad995fd
## What changed
- Add a best-effort MCP configuration refresh that logs per-thread load errors and continues refreshing the remaining threads.
- Use the best-effort path after account or plugin changes before invalidating MCP runtimes.
## Testing
- Add a test confirming that a thread with a configuration load failure does not prevent healthy threads from receiving updated configuration.
GitOrigin-RevId: 34708d46f63fbe8617567ced16b4c199456ab078
## Why
MCP config reloads updated resolved server and authentication values, but did not
carry managed server constraints or plugin requirements into active threads.
## What changed
- Refresh MCP state from the typed thread config, including its managed
requirements, while retaining the thread's user layer and unrelated settings.
- Apply the refreshed config directly through `CodexThread` instead of encoding it
as a protocol operation.
- Re-evaluate effective plugins immediately after account changes so their MCP
requirements reach existing threads.
## Testing
- Cover replacement and enforcement of managed server and plugin requirements.
- Verify refreshed MCP settings are installed without changing the active model.
GitOrigin-RevId: 3cf0d69f51ef4893a4d722ee803fcbfdf1cd959e
## Why
MCP elicitation reviewers are reused across runtime refreshes, while an active
turn can retain the approval settings it started with. Reviewing against that
turn could therefore apply stale authority after session settings changed.
## What changed
- Read the latest published MCP runtime configuration when reviewing an
elicitation, including the approval policy, permission profile, configuration
layers, and reviewer selection.
- Apply `never` and granular MCP-elicitation policy decisions before routing an
eligible request to Guardian.
- Keep MCP runtime startup registered for refresh invalidation through session
creation.
## Testing
Added coverage that refreshes a running session and verifies the same reviewer
uses the latest authority for Guardian routing, denial, and empty-form
auto-approval.
GitOrigin-RevId: 826a157aa70fc8e3a9e3a14ecb0261bf7b63f63a
## Why
MCP configuration can change while a thread is still starting, before it appears in the thread manager's loaded-thread list. In that window, invalidation could miss the new thread and leave it with a stale MCP runtime.
## What changed
- Centralize MCP runtime invalidation in `ThreadManager` so it refreshes loaded threads and marks in-progress thread startups for refresh after publication.
- Use the centralized invalidation path for account and plugin changes.
- Invalidate MCP runtimes after successful server and plugin OAuth logins.
## Testing
- Add a regression test that pauses thread startup, invalidates MCP runtimes, and verifies that the newly published thread refreshes its MCP projection.
GitOrigin-RevId: 8944f5a21816a1405e038a0d4c08b66362ea9368
## Why
Executor skills that disallow implicit invocation are omitted from `skills.list`, so an explicitly selected skill did not provide the authority and package identifiers needed to read its referenced resources.
## What changed
- Add `resource_access` metadata to injected instructions for explicit-only executor skills.
- Teach the `skills.read` description to accept that metadata as well as values returned by `skills.list`.
- Keep discoverable executor skill instructions unchanged.
## Testing
Add an app-server integration scenario that selects an explicit-only executor skill, confirms it remains absent from `skills.list`, and reads a referenced file through `skills.read`.
