## What changed
- Add `EnvironmentNetworkPolicy` as a serializable view of portable domain,
Unix-socket, upstream-proxy, and local-binding restrictions without exposing
controller-owned proxy runtime settings.
- Add an optional `network_policy` field to `EnvironmentConfig` and re-export
the policy and related permission types through the core APIs.
- Reject owner-provided network policies during environment preview and
readiness until runtime enforcement is implemented, while preserving the
existing controller policy when the field is absent.
## Testing
- Cover rejection through both environment preview and readiness, including
preservation of the existing environment selection.

## Why
The app directory is a discovery catalog and can include apps that are not
callable in the active thread. Using it for `$` suggestions can therefore
offer mentions that cannot be used.
## What changed
- Load mention candidates from `app/installed`, enrich callable apps through
bounded `app/read` batches, and retain compatibility with app servers that
do not support `app/installed`.
- Keep the mention catalog separate from the `/apps` directory cache and scope
results to the current thread, workspace, and account.
- Refresh mentions after app notifications, enablement changes, configuration
updates, and apps MCP readiness, while immediately removing disabled apps.
## Testing
Add coverage for batching and fallback behavior, stale scoped results,
notification refreshes, enablement changes, MCP startup races, and filtering
non-callable apps from mentions.
GitOrigin-RevId: 4d9e20794aed30cc97120170792fb555b86fe1e7
## Why
Creating the telemetry shutdown thread during shutdown can fail under resource
pressure, including when the native thread guard page cannot be allocated.
## What changed
- Start and verify a dedicated shutdown worker when `OtelProvider` is created.
- Send the provider to the prepared worker for bounded shutdown, while preserving
timeout behavior and avoiding a potentially blocking destructor if worker
preparation failed.
- Rename the fallible provider constructor to `try_new`.
## Testing
Add Unix regression coverage that injects guard-page allocation failures, plus
coverage for worker preparation failure, successful shutdown, and timeouts.
GitOrigin-RevId: 3656298078a800a7fa392437c2ee4a68753092e3
## Why
The app server sends sub-agent activity in both item-started and item-completed
notifications, causing the TUI to add the same activity to history twice.
## What changed
Render live sub-agent activity when the item completes instead of also rendering
it when the item starts. Preserve the existing replay behavior.
## Testing
Add a regression test that sends matching started and completed notifications
and verifies that the activity produces one history cell.
GitOrigin-RevId: 76a66f3657fe297f37067ed672ab9642997b4499
## What changed
Gate plugin hook resolution in `hooks/list` on both the hooks and plugins
feature flags. When hooks are disabled, return the default empty plugin hook
outcome without loading plugin hook sources or warnings.
GitOrigin-RevId: 166070576effaba248b790c4f2a47e6e9a7b1112
## Why
MCP requests can contain sensitive headers and tool-call bodies. Following a
cross-origin redirect could disclose them to another server.
## What changed
- Follow redirects only when every hop remains on the configured server's
origin, and require HTTPS for redirects on non-loopback hostnames.
- Preserve standard redirect method and body handling while sharing the
original timeout and enforcing a 10-hop limit.
- Avoid replaying plaintext proxy credentials across redirects, while leaving
OAuth requests that stop at redirects unchanged.
## Testing
Add coverage for same-origin and cross-origin redirects, redirect methods,
headers and bodies, proxy credentials, timeouts, hop limits, and legacy MCP
tool calls.
GitOrigin-RevId: 3e267911a1665ad8c2fc63825099a758770f4d68
## What changed
- Register `in_app_chat` and `in_app_dictation` as stable, default-enabled feature gates for desktop apps.
- Allow requirements to disable either capability and expose both keys in the generated configuration schema.
## Testing
- Add configuration tests that verify enterprise requirements can disable each gate.
GitOrigin-RevId: 5bba35d710fb0b6924aa55df98b2e013fa288f6d
## What changed
- Add `cli_auth_credentials_store` and `chatgpt_base_url` as exact managed requirements loaded from local requirements configuration.
- Apply these requirements to runtime and bootstrap authentication configuration, overriding user-configured values.
- Expose the managed values through `configRequirements/read` and reject attempts to change them through config write APIs.
- Ignore these local-only authentication requirements in cloud-managed requirement layers.
## Testing
- Cover requirement loading and composition, runtime and bootstrap overrides, app-server responses, and read-only config writes.
GitOrigin-RevId: 8ea9c096386072036ca5441f3d48af8707988a65
## Why
Unified exec could drop network approval registration when a selected environment used a Windows working directory on a non-Windows host because the trigger path could not be converted to a host absolute path.
## What changed
- Keep network approval trigger working directories as `PathUri` values and render them with their inferred native path syntax for Guardian requests.
- Fall back to the selected turn environment only when a trigger path can be converted to a host absolute path.
- Reject selected environment working directories larger than 8 KiB at the thread-manager validation boundary.
## Testing
- Cover managed-network approval registration for a foreign Windows working directory.
- Verify that oversized working directories are rejected as invalid `thread/start` requests.
GitOrigin-RevId: 646fbf12115a35a7e5cb04b511464797bee6647b
## Why
Resumed and forked threads need their persisted Guardian risk state available when routing later approval requests.
## What changed
- Initialize a session's `SecurityRiskScore` from the latest score in its rollout history when no score was supplied explicitly.
- Preserve the inherited score when resuming or forking a thread so low-risk actions can skip redundant Guardian reviews.
## Testing
- Add app-server coverage for inheriting the latest Guardian score when resuming and forking threads.
GitOrigin-RevId: 95a6c803f8dae75516d1da9d66a722379a0a7ef2
## Why
Config reads arriving while a long-running shared read was active waited for that
request to finish, even though they could safely run concurrently.
## What changed
- Admit newly queued shared reads into the active batch until an exclusive write
is queued, preserving the write as a fairness barrier.
- Treat `hooks/list` and `configRequirements/read` as shared config reads.
- Cover concurrent reads, read/write ordering, and config reads completing
alongside a `skills/list` request.
GitOrigin-RevId: 8194301c2ba60be0fc71b8915923af9accc745dc
## What changed
- Add end-to-end app-server tests for MCP tool approvals with Guardian V2 and automatic review enabled.
- Verify that sampling receives the thread context, uses a thread-scoped prompt cache key, and persists the resulting action risk score.
- Cover both routing outcomes: low-risk actions skip later Guardian reviews, while high-risk actions continue through full review.
GitOrigin-RevId: 78ba2b0560caf701ad333785c4dda4f7d2be4f2c
## Why
Durable thread queues can be updated through another SQLite connection, but loaded idle threads need to notice those updates before they can dispatch the new messages.
## What changed
- Track a durable revision for each thread queue, including backfilling existing queues and updating revisions on inserts, updates, and deletes.
- Poll SQLite's data version and query revisions to find changed queues for loaded threads.
- Wake idle threads with pending external messages, discover queued work when threads are loaded or resumed, and retry each thread independently so one blocked queue does not stall others.
## Testing
- Cover cross-runtime queue writes, edits, independent dispatch, wake retries, and resumed threads.
- Cover migration backfills and revision tracking for queue updates and deletes.
GitOrigin-RevId: 906d902bbf6a760be206a1b2c08fd71427b63c46
## Why
Building a resume-picker preview for a legacy session should not require loading its full thread history.
## What changed
- Read up to six preview lines by scanning at most 1 MiB from the end of a local legacy rollout.
- Fall back to the existing history hydration path when the local file is unavailable, the bounded scan is incomplete, or the tail contains a rollback.
- Keep the initial `thread/read` request turn-free while loading the preview.
## Testing
Added coverage for compaction, rollbacks, oversized records, exhausted scan budgets, and app-server request parameters.
GitOrigin-RevId: a8950f03d8b56323f268fd3355c6a38a16cb9833
## Why
Direct access to shimmer primitives can bypass the reduced-motion handling
introduced in https://github.com/openai/codex/pull/20564.
## What changed
- Make `shimmer` a private child of `motion` and restrict `shimmer_spans` to
its parent module, so Rust visibility enforces the animation boundary.
- Remove the source-scanning regression test that previously checked this
boundary with regular expressions.
GitOrigin-RevId: 1f4cccacaa907992c636cd1e9cd2829b7653f811
## What changed
- Reuse shared directory fixtures and local and remote app-server instances across the resume cwd case matrix.
- Seed the runtime working-directory override directly so each case focuses on resume behavior without starting and replacing an extra thread.
- Run the test on a four-thread Tokio runtime and shut down each shared server after all cases complete.
GitOrigin-RevId: 4bc4978abc546882f26bcb5e3591ff9673758b4a
## Why
Pet tests reuse the same blank WebP spritesheet fixture, so encoding a new image
for every temporary path does unnecessary repeated work.
## What changed
Encode the test spritesheet once with `LazyLock`, then write the cached WebP bytes
to each requested fixture path.
GitOrigin-RevId: 26d75bb1bac448717ca63aeb82eb4e500c86fad8
## Why
The 1,000-character human-like typing test waited on the wall clock after
every keypress, making the test unnecessarily slow.
## What changed
Advance an injected timestamp by the recommended paste flush delay and flush
the paste-burst detector explicitly after each character. This preserves the
coverage that slow typing appears directly without creating a paste
placeholder, without sleeping between keypresses.
GitOrigin-RevId: 0c1beb40283f7d73a381cd221725ab4227c8e233
## What changed
Construct the oversized unified diff fixture directly instead of generating it
from two large input strings. Keep the fixture just above
`MAX_HIGHLIGHT_LINES` so the test continues to verify that syntax highlighting
is skipped for large updates.
GitOrigin-RevId: 8f8853e03a50ff9f53e77b2ba0956cf85ee17c07
## Why
MCP tool results can contain multi-megabyte image, audio, or resource bodies,
even though TUI history renders only summaries for those content types.
## What changed
- Project completed MCP results into width-independent display data, dropping
media and resource bodies that history does not render.
- Preserve text output, JSON fallbacks, error state, Node REPL rendering, and
the fully decoded image-output marker.
- Add tests covering width-dependent rendering, image validation, and Node REPL
text fields on non-text and unknown content blocks.
GitOrigin-RevId: 2cfddf0864093e6837a4431e541f7a9cab544a68
## Why
Keeping overflowing separators with the following word can add whitespace-only
rows and make composer wrapping differ from the queued-input preview.
## What changed
- Hang breakable whitespace from the preceding visual row at soft word breaks
while preserving the underlying editable text.
- Keep indentation, trailing whitespace, mandatory breaks, and nonbreaking spaces
visible and editable according to their existing semantics.
- Align cursor placement, scrolling, vertical navigation, masked rendering, and
styled overlays with the visible wrapped content, including after resizes.
## Testing
Add focused wrapping, rendering, cursor, editing, scrolling, navigation, Unicode
separator, long whitespace-run, and resize coverage.
GitOrigin-RevId: 7fbdb0a4bf33cfee20c4c19dca5aee74df4f892c
## Why
Windows named pipe servers can impersonate connected clients. IDE context
connections only require the server to identify the client, so they should not
grant broader impersonation rights.
## What changed
Open Windows IDE context pipes with `SECURITY_SQOS_PRESENT` and
`SECURITY_IDENTIFICATION`, limiting the server's impersonation token to the
identification level.
## Testing
Add a Windows regression test that connects to a named pipe, asks the server to
impersonate the client, and verifies that the resulting token has the
`SecurityIdentification` level.
GitOrigin-RevId: 51ef080f3367857987e03b0113a476040ea40e56
## Why
Headers configured for an MCP resource can contain credentials and must not be
forwarded to a different origin during OAuth discovery, registration, or token
exchange.
## What changed
- Apply configured resource headers only to OAuth requests on the MCP resource
origin, while allowing OAuth-generated headers to take precedence.
- Follow credentialed OAuth redirects only when each destination remains on the
resource origin. Preserve redirect method semantics, the overall timeout, the
response size limit, and a maximum of 10 redirects.
- Use the Codex MCP user agent for requests to authorization-server origins.
## Testing
Add coverage for cross-origin header isolation, same-origin dynamic client
registration redirects, OAuth header precedence, token refresh, timeout
accounting, and response size limits.
GitOrigin-RevId: 609d06e2b065e4aa9ca5382b4ae60455f9e26db9
## What changed
- Define MCP server identities, matchers, requirements, and per-plugin MCP requirements in the new `codex_protocol::mcp_policy` module.
- Keep requirement validation and matching against `McpServerConfig` in `codex-config`.
- Re-export the moved types from `codex-config` to preserve existing consumers.
GitOrigin-RevId: ad8a107e3085191241a5766f061dd004103e21e6
## Why
Short continuation prompts such as `continue` do not contain enough context for
skill selection on their own.
## What changed
- Add the `task_context_fusion_v1` shadow selector, combining the current request
with up to two prior substantive requests and recently relevant skills.
- Record explicit skill intent and successful skill invocations for future turns,
while excluding same-turn observations from predictions.
- Bound retained requests, augmented queries, and skill history, including safe
truncation at UTF-8 character boundaries.
## Testing
Add unit and extension tests for continuation prompts, explicit intent, turn
isolation, cold thread state, bounded history, and unchanged control selectors.
GitOrigin-RevId: 72eca3f0d64620a0d24e95d5675f126ac982f8c7
## Why
Guardian stores a `SecurityRiskScore` before advancing its scored-tool-call
counter. Waiting only for the score can therefore let the test continue while
the asynchronous sampler is still updating its progress state.
## What changed
Wait for `latest_scored_tool_call` to advance before exercising Guardian v2
approval decisions, and reuse the same progress tracker for the subsequent
assertions.
GitOrigin-RevId: 3d92c9a3ccf52f4f43a2454aac60d2479258c1c8
## What changed
- Track app-server turn lifecycle events for OpenAI API-key sessions when OTLP telemetry export is enabled.
- Query the turn-cost endpoint after completed or aborted turns and emit `codex.turn_cost` with the estimated USD cost, interruption state, model, speed, and reasoning effort.
- Preserve provider organization and project headers, wait for all observed responses to be priced, and retry pending or transiently failed queries with bounded tracking.
- Re-probe availability after authentication changes and shut the worker down with other app-server background tasks.
## Testing
- Cover late API-key login, transient probe failures, telemetry after thread removal, and turns with multiple responses.
- Verify turn-cost requests use API-key authentication and provider scope headers and deserialize priced response data.
GitOrigin-RevId: a303162a54798b554fcb2e9e2b372e1cf9f49f39
## Why
Guardian V2 should not override a managed approval-reviewer policy that excludes
the user reviewer.
## What changed
- Force `features.guardianv2` off when `allowed_approvals_reviewers` does not
include `user`, for both local requirements and cloud config bundles.
- Preserve Guardian V2 when the user reviewer remains allowed or when only
legacy Guardian feature settings are present.
- Return the effective disabled value through `config/read`.
## Testing
Added coverage for cloud requirements and the app-server config RPC.
GitOrigin-RevId: 82b6d0aaf47fbaa58ae349d4e56777cd442f5807
## What changed
- Track the latest tool call and latest scored tool call for each Guardian v2 thread.
- Skip approval review when the score lags by more than `max_tool_call_lag` tool calls.
- Add `max_tool_call_lag` to the Guardian v2 configuration and schema, with a default of three.
## Testing
- Cover approval review at, above, and after recovering from the configured lag limit.
- Cover deserialization of `max_tool_call_lag`.
GitOrigin-RevId: fd870e143d95ee76491180e2aed742717248ff78
## Why
Guardian sampling can encounter temporary connection or service failures while
opening a WebSocket, starting a request, or consuming its response stream.
## What changed
- Retry transient transport, streaming, rate-limit, and server failures up to
two times across the full sampling flow.
- Recover from unauthorized responses through the configured auth manager and
discard pooled connections that may contain stale credentials.
- Allow sampler initialization to continue when its initial WebSocket prewarm
fails, so the first sample can establish a fresh connection.
## Testing
Added coverage for recovery after prewarm failures and `503` responses, and for
stopping once the transient retry budget is exhausted.
GitOrigin-RevId: af74c2df95c4241184ca641ef4418db6aa4ab695
## What changed
- Stop fetching the ChatGPT workspace `enable_plugins` setting.
- Let the effective Codex feature configuration control app and plugin APIs,
plugin-provided skills and hooks, and experimental feature reporting.
GitOrigin-RevId: 46aebf0f07cd47e093e48663e41207cdf9a38c9f
## What changed
- Add shadow selectors that fuse recently invoked skills with character routing-card matches using reciprocal rank fusion.
- Add a second variant that also incorporates weighted lexical matches.
- Record both variants in the existing shadow-selection experiment, capped at 50 candidates.
## Testing
- Cover cold starts, duplicate removal, short exact matches, deterministic ranking, result limits, and truncation metadata.
- Extend the skills integration test to verify both selectors recover a skill invoked on an earlier turn.
GitOrigin-RevId: 4ff9e91da8cb49ecbce54ab8e760820616e1a1d3
## What changed
- Add optional `guardian_v2` model-message defaults for classifier instructions,
review thresholds, reasoning effort, transcript selection and limits, and
action and compaction token limits.
- Apply those defaults when Guardian v2 samples a tool call, while preserving
explicit `[features.guardianv2]` settings over catalog values.
- Preserve the new catalog configuration when applying model overrides.
## Testing
- Cover model-catalog serialization and model override behavior.
- Verify that sampling uses catalog defaults while retaining local overrides.
GitOrigin-RevId: 4ae9ec235c647acbca05a20b7c4b87a4e1331161
## What changed
- Add the `features.guardianv2.transcript.include_images` opt-in setting.
- Include recent images from user and assistant messages and configured tool outputs in Guardian v2 sampling requests.
- Bound image context to the four most recent images and 8 MiB total, and omit image detail hints when constructing the sampling request.
## Testing
- Cover configuration parsing and image forwarding from messages and tool outputs.
GitOrigin-RevId: b0ae6b6182535fd084ea103ed01dc3c803d7d1f7
## What changed
- Add `max_parent_compaction_tokens`, defaulting to 25,000 tokens, to the Guardian v2 feature configuration.
- Reuse the latest encrypted parent compaction only when its complete serialized item fits within the configured limit.
- Fail closed with the maximum action-risk score when the latest encrypted compaction is oversized, instead of sampling with older context.
## Testing
- Cover exact-boundary and oversized compaction items, including oversized passthrough metadata.
- Verify that an oversized latest compaction bypasses sampling and prevents approval.
GitOrigin-RevId: 0b308e7bec0f41d46433dfdf656948cee5cba667
## What changed
- Add `[skills].max_context_tokens` to override the token budget used to render the available-skills catalog.
- Require a positive value and cap configured budgets at 10,000 tokens.
- Preserve the existing default of 2% of the model context window when the option is unset.
## Testing
- Cover configuration parsing, override behavior, the 10,000-token cap, and catalog rendering within the configured budget.
GitOrigin-RevId: f29ddcb57fc2d800c0006d03e1c33cbe3ab6272d
## What changed
- Ignore the default `CODEX_HOME/managed_config.toml` on Windows and exclude it
from local managed-configuration detection.
- Emit a startup warning when the deprecated file exists, directing users to
`%ProgramData%\OpenAI\Codex\requirements.toml` for enforced settings or
`config.toml` for defaults.
- Preserve explicit managed-config path overrides and Unix legacy-file support.
## Testing
- Add Windows tests covering ignored legacy settings, the startup warning, and
managed-configuration detection through `requirements.toml`.
GitOrigin-RevId: a61d9d9912b13817ba82807a486c9ed92e49c7bc
## What changed
- Add an optional restrictive execution policy to `EnvironmentConfig` and merge it over the active command policy for shell execution and approval decisions.
- Reject environment policies that contain allow rules, so environment configuration can only tighten command access.
- Include the environment policy fingerprint in cached approval keys so policy changes require fresh session approvals.
## Testing
- Cover restrictions overriding saved prefix approvals, policy changes invalidating session approvals, and environment overlays remaining effective when model-specific prefix filtering is active.
GitOrigin-RevId: e94f877549ed5e0f577b8cb52f3c1872c58f029d
## Why
`CODEX_EXEC_SERVER_NOISE_AUTH_TOKEN` is an execution-server credential and
must not be exposed to model-reachable commands or command hooks, including
when shell environment policy explicitly sets a case variant of the name.
## What changed
- Add `CODEX_EXEC_SERVER_NOISE_AUTH_TOKEN` to the shared list of
non-inheritable environment variables.
- Keep the environment variable constant in `codex-protocol` so the exec
server and environment scrubber use the same definition.
- Verify case-insensitive removal after policy overrides for shell commands
and command hooks.
GitOrigin-RevId: 759b224b6a7fb4f56f7b1a6d94ffbb0b188c658f
## What changed
- Group consecutive successful agent and unified-exec startup commands into a compact `Ran N commands` entry while preserving their full transcript.
- Flush command groups at interaction boundaries, after failures, and after 32 completed commands. Keep manual shell commands and failed or declined commands visible.
- Apply the same grouping rules when replaying thread history without duplicating command starts or disturbing unrelated active commands.
## Testing
- Add TUI coverage for live and replayed grouping, transcript preservation, failures, overlapping commands, group limits, and interaction boundaries.
GitOrigin-RevId: d6602a20201644012fcff3d6cecf4690024383a9
## Why
App-server request deserialization otherwise ignores unknown fields, so clients using the removed `permissionProfile` field could have their requested permission settings silently ignored.
## What changed
- Reject `permissionProfile` with an invalid-params error on `thread/start`, `thread/resume`, `thread/fork`, and `turn/start`.
- Direct clients to select a named profile through `permissions` instead.
- Continue accepting unrelated unknown fields for forward compatibility.
## Testing
- Cover rejection of the obsolete field on all four affected methods and verify that the connection remains usable.
- Cover successful `thread/start` requests that combine named `permissions` with an unknown field.
GitOrigin-RevId: a63764fb899bc5f212d60617dc32e911bde8073e
## What changed
- Probe the configured Responses inference endpoint with Codex's route-aware HTTP client, including configured proxy and custom CA behavior.
- Classify TLS, proxy authentication, proxy configuration, resolution, and timeout failures into actionable diagnostics.
- Report privacy-safe macOS system proxy state and suggest enabling `respect_system_proxy` when a configured proxy is otherwise unused.
- Preserve system-root fallback when a custom CA is invalid, and account for provider-specific API key configuration when selecting the probe route.
## Testing
- Cover inference endpoint selection, invalid custom CA fallback, proxy authentication failures, TLS classification, and macOS proxy reporting.
GitOrigin-RevId: c30a3ca5a332119e2b2f8c65341ef9b2251a28a2
## Why
Permission profiles written before the rename to `:workspace_roots` can still
contain `:project_roots`. Treating that token as unknown ignores its entries and
can drop filesystem restrictions.
## What changed
- Parse `:project_roots` as an alias for `:workspace_roots`.
- Cover deny rules and read-only subpath carveouts in legacy profiles.
GitOrigin-RevId: 10aafc9e15372d1a8bcc2dbcf3ad7cc987f4e67e
## What changed
Stop visiting remaining `ColumnRenderable` children once the render position
reaches the bottom of the available area.
GitOrigin-RevId: 5b7f2c657f65879119b1b840e82f47b1c5f9e3db
## What changed
- When the composer is empty in Vim normal mode, make the configured history-up binding restore the latest queued follow-up for editing.
- Remove the restored message from the queue so submitting the edited version replaces it instead of creating a duplicate.
- Preserve normal history navigation when the composer has text or a popup is active, and honor remapped Vim bindings.
## Testing
- Add TUI tests covering repeated edit-and-requeue cycles and a remapped history-up binding.
GitOrigin-RevId: 0b04dd964d3fc6fdcd10712aa4d5fd81cbbd2255
## What changed
- Carry `ShellEnvironmentPolicy` in each resolved `EnvironmentConfig` and use
the selected turn environment's policy for shell commands, user shell tasks,
and unified exec.
- Infer the policy from the thread configuration when an environment does not
provide its own resolved configuration.
- Redact the policy from `EnvironmentConfig` debug output because it can contain
explicit environment variable values.
## Testing
- Verify shell handlers and unified exec filter inherited variables according
to the selected environment while preserving its explicit overrides.
GitOrigin-RevId: 9f6a52aa4af60e5f17251a0e1b11e1926b779055
## What changed
- Define and export `RequirementsExecPolicy` from `codex-execpolicy`, alongside the
underlying `Policy` type.
- Re-export the type from `codex-config` so existing config consumers retain the
same API.
- Preserve its order-independent equality and `AsRef<Policy>` behavior.
GitOrigin-RevId: e94c56b36824d07f2bc7ba14ce40bdb770d4ab46
## What changed
- Add `/cd [path]` for changing an idle local session's working directory while preserving conversation history. Relative paths resolve from the current directory, and omitting the path selects `~`.
- Reload project configuration, instructions, permissions, keybindings, file search, and hooks for the destination before replacing the active session.
- Reject unsafe transitions, including active or queued work, background terminals, remote environments, untrusted destinations, and incompatible permission profiles.
- Add `/pwd` and its `/cwd` alias to display the current working directory, and discard asynchronous results left over from the previous directory.
## Testing
- Cover command parsing, aliases, default paths, session eligibility, transition failures, history preservation, destination policy loading, hooks, and stale events.
GitOrigin-RevId: 1a987c029f157a087ba02c0f26e022260409132b
## What changed
Load the persisted maxima for `updated_at_ms` and `recency_at_ms` with separate
scalar subqueries during state initialization. This restores each timestamp
counter independently when the maxima belong to different threads.
## Testing
Add a regression test that reopens the state database and verifies both
independent maxima are restored.
GitOrigin-RevId: aeb9cc005d52c4a02dc7a220a817e6d40c0e01d4
