## Why
MCP inventory can be cached or collected separately from a thread's live
connections, so tool availability alone does not describe the current runtime
state.
## What changed
- Add a nullable `runtimeStatus` to `mcpServerStatus/list` for thread-scoped
requests, covering not-started, starting, connected, authentication-required,
failed, cancelled, and disabled connections.
- Observe published connection state without starting or reconnecting servers,
and return an unknown status when no thread is supplied or the active
configuration no longer matches the published registration.
- Show connection state and tool counts in the compact `/mcp` view while
retaining the detailed inventory in `/mcp verbose` and compatibility with
servers that omit `runtimeStatus`.
## Testing
- Cover runtime status transitions, deferred and disabled servers, closed
transports, configuration changes, protocol compatibility, and TUI rendering.

## Why
The `fast-mode` status item showed `Fast off` even when the selected model did not support Fast mode.
## What changed
- Hide the Fast mode status value when the current model is known not to support Fast mode.
- Continue showing the value for supported and uncatalogued models.
## Testing
- Cover visibility updates when switching among supported, unsupported, and uncatalogued models.
- Update the footer snapshot to verify that an unsupported model omits the Fast mode value.
GitOrigin-RevId: c297655189efc719b2097c2aa415029b01d6873e
## What changed
- Open a picker for `/copy` with the whole response plus each fenced code block and blockquote from the latest response.
- Label code blocks by language, show content previews, and preserve source whitespace and nested quote Markdown when copying an individual target.
- Keep the picker from disturbing terminal scrollback or queued input, retain clipboard leases, and avoid writing copied content to the session log.
## Testing
- Add coverage for target extraction, picker navigation and cancellation, exact copied content, plan responses, queued input, scrollback preservation, clipboard failures, and session logging.
GitOrigin-RevId: 77a35bc99f4f45932d39914f9a709b30fe8cd7c2
## What changed
- Add a top-level `allow_browser_and_computer_use` requirement.
- Support browser requirements for history access, automatic review, persistent approvals, and default or per-origin access policies.
- Support computer-use requirements for persistent approvals, default app access, macOS bundle IDs, Windows AUMIDs, and Windows executables.
- Preserve these settings and their sources when composing layered requirements.
## Testing
- Cover deserialization, empty-value detection, source propagation, and layered TOML merging for the new requirements.
GitOrigin-RevId: d14a10b64465f1c54e9bcc3795dc93031e6b029b
## What changed
- Use one binding-aware description for each keymap action instead of swapping
in separate text for the selected item.
- Keep the action menu content unchanged as the selection moves between items.
- Update key and key-chord replacement descriptions to name the affected
binding directly.
## Testing
- Extend the keymap action menu test to move through every item and verify that
the rendered picker remains unchanged.
GitOrigin-RevId: bbd2bd08ca444c76c28c5213ae077ad85bc50f27
## Why
Draining every queued active-thread event in one foreground pass can overrun the
frame budget. Buffered thread events can also race ahead of queued replay and
startup app events, causing the TUI to switch views before the corresponding
history and operations have been applied.
## What changed
- Bound active-thread draining to one target frame interval and leave remaining
notifications queued for a later frame.
- Prioritize queued app events over active-thread events so replay state is
applied before buffered closures or other thread notifications.
- Block startup input only for pending requests, rather than ordinary queued
notifications whose draining yielded at the frame deadline.
- Leave selected side-thread closure handling to the foreground event loop.
## Testing
Added tests covering deadline-limited notification draining and foreground
handling of a selected side thread closing.
GitOrigin-RevId: 41080d3df13ca308eec1ea0fbb0ba067a4640c4c
## What changed
- Add unbound `previous_permission_mode` and `next_permission_mode` actions to
`tui.keymap.chat` so users can configure shortcuts that cycle through the
available built-in permission modes.
- Apply shortcut selections only to the active session, without writing them
to `config.toml`, and report update failures in the transcript.
- Exclude modes disallowed by managed requirements or platform safety checks,
reject printable-key bindings, and ignore these bindings in project config.
## Testing
- Cover mode cycling, unavailable modes, session-only updates, server errors,
stale threads, keymap validation, and project-config sanitization.
GitOrigin-RevId: c3cfdf1e732b7b7bfe8f53fcac19a37e593bbfab
## Why
`codex agents` rejected invocation-specific configuration, preventing the
dashboard from applying settings when starting a shared thread.
## What changed
- Accept interactive options such as model, approval, sandbox, search, working
directory, and configuration overrides when opening the agents dashboard.
- Forward supported session-flag configuration into threads started through an
embedded or remote app server, while excluding unrelated values.
- Continue to reject initial prompts and images, along with local provider and
additional-directory settings that cannot be applied to a remote server.
## Testing
- Cover accepted dashboard options and rejected incompatible inputs.
- Verify that explicit feature and sandbox overrides reach shared threads in
both embedded and remote modes.
GitOrigin-RevId: f10aa1e16ff62b49d55679e987d9e458438ba3f8
## Why
Pending input previews display at most three wrapped rows, but previously wrapped every logical line before truncating the result. This made rendering do unnecessary work for very large multiline inputs.
## What changed
Limit pending steers, rejected steers, and queued follow-up inputs to four source lines before wrapping: three for the preview and one to detect overflow and render the ellipsis.
## Testing
Keep multiline preview coverage for queued messages and pending steers, including blank lines near the truncation boundary.
GitOrigin-RevId: 4c300b13532983ff9c3bdfbd62d6ca722ea3a5aa
## What changed
- Add `hostname` as a selectable status-line item and show it in setup previews.
- Read the normalized operating-system hostname without triggering DNS resolution, and omit the item when no hostname is available.
## Testing
- Cover hostname normalization, status-line rendering, and setup and surface previews.
GitOrigin-RevId: c5e4e0ee1dba6e4bfdf942562a6b037835ff9e69
## What changed
- Add experimental `mcpServer/event/stream/start` and `mcpServer/event/stream/stop` requests for hosted apps, plus `mcpServer/event/stream/notification` forwarding.
- Scope subscriptions to the owning app-server connection and subscribed thread, enforce unique IDs and a per-connection limit, and clean them up when the thread is unsubscribed or the connection closes.
- Wait for the MCP active notification before completing startup, retry streams that close immediately, and terminate them when authentication or hosted runtime ownership changes.
## Testing
- Add an app-server integration test covering activation, event forwarding, duplicate subscription rejection, and explicit cancellation.
GitOrigin-RevId: 8a6fc1615adfc5af7e67def3b824fa5909ab3e7b
## What changed
- Add `additional_developer_instructions` to managed requirements and expose it through `configRequirements/read` as `additionalDeveloperInstructions`, independently of ordinary developer instructions.
- Include the managed instructions in model context, emit explicit replacement or removal messages when requirements change, and preserve the current value across compaction, resume, and agent forks without duplication.
- Reject managed instructions whose rendered context exceeds 10,000 estimated tokens.
## Testing
- Cover requirements layering and API serialization, context updates and removal, size validation, repeated model requests, compaction and resume, rollout migration, and agent forks.
GitOrigin-RevId: bc0b70fb7988944c2f68176dff55f5ed61eb46c8
## What changed
Return the initial wrapping ranges directly when the composer input produces a
single line and its byte length is less than the available width. This avoids
the additional grapheme and word-boundary pass for input that cannot wrap.
GitOrigin-RevId: 55d990a354fcc61e9a90d5796b4b39d16742cc50
## Why
A newly started thread may not have materialized its rollout before the TUI
receives `ThreadStarted`. Trying to infer session state from that path can wait
through rollout reader retries even when a lifecycle response already provided
the authoritative session.
## What changed
- Preserve session state already stored for a known thread instead of inferring
it again from `ThreadStarted`.
- Continue updating agent-picker metadata from the notification.
- Restrict fallback session inference to newly observed `ThreadStarted`
notifications that do not already have session state.
## Testing
Added a startup test that verifies a known thread routes `ThreadStarted`
immediately, retains its configured session, buffers the notification, and
updates agent metadata when the rollout does not exist yet.
GitOrigin-RevId: 7ed98fb46df17566c4a61ac677f60fc8d94f7321
## What changed
- Add `in_app_browser.allow_external_browser_settings_import` to managed requirements, preserving explicit Boolean values through layered composition while leaving an omitted value unset.
- Return the policy as `inAppBrowser.allowExternalBrowserSettingsImport` from `configRequirements/read` and include it in the generated protocol schemas.
- Keep the import policy independent from the in-app browser feature flag and agent Browser Use requirements.
## Testing
- Cover parsing, managed-layer precedence, invalid values, user and session override resistance, and app-server response serialization.
GitOrigin-RevId: efa2621d2b1cf503f1bee2505d9914cb4fb7221d
## Why
The TUI session logger is meant to record only the variant for unhandled app
events. Parsing `Debug` output removed tuple payloads but retained fields from
struct variants.
## What changed
Derive `IntoStaticStr` for `AppEvent` and use that conversion when recording
fallback `app_event` entries, so the `variant` field consistently contains only
the enum variant name.
GitOrigin-RevId: 5b539f414269c6b001e69cf9496db5b49aceb759
## What changed
- Add the configurable `vim_normal.replace_char` action, bound to `r` by default, to replace the grapheme under the cursor while remaining in normal mode.
- Support change-operator motions such as `cw`, `c$`, `cj`, and `ck`, plus the repeated `cc` command for changing the current line.
- Let `Esc` cancel a pending replacement before it reaches composer-level handling.
- Preserve existing custom Vim bindings and chord prefixes when introducing the new default.
## Testing
- Cover replacement, grapheme boundaries, remapping and unbinding, change motions, cancellation, keymap conflicts, and keymap picker snapshots.
GitOrigin-RevId: 98feb4eeb57142c37adb73abfe58d1f703b9270d
## What changed
- Add Linux-specific install and launch guidance to the generic and paid tooltip pools when `DISPLAY` or `WAYLAND_DISPLAY` is set.
- Keep the Linux tooltip hidden in WSL and headless sessions, and preserve platform-specific macOS and Windows behavior.
## Testing
- Add coverage for native graphical Linux, WSL, headless Linux, macOS, and Windows tooltip selection.
GitOrigin-RevId: cbe9435db064d5718a591db363dcb7cc1429d5ee
## Why
Starting an archived session with `codex resume` or `codex fork` stopped with
guidance to run a separate `codex unarchive` command first.
## What changed
- Detect archived-session startup failures and offer to unarchive and retry the
requested operation.
- Allow the user to cancel without modifying the archived session.
- Render the confirmation in the alternate screen when available and preserve
inline terminal context when `--no-alt-screen` is set.
- Preserve `--no-alt-screen` whether it appears before or after the `resume` or
`fork` subcommand.
## Testing
- Cover confirmation, cancellation, retry behavior, and unrelated startup
failures for both resume and fork.
- Add prompt interaction and terminal rendering coverage, including narrow and
inline viewports.
GitOrigin-RevId: 382cdbd15b5d12c091e554d6d3a2f9b3589654f4
## What changed
- Render `StrictReviewRequired` notifications as warning history cells that explain tool calls may take extra time.
- Preserve the active command and task-running state when the notification arrives.
## Testing
- Add a TUI snapshot test covering the warning and continued command output.
GitOrigin-RevId: bf01b612a22b537b247b6df6818080fc73b5414d
## Why
The Linux sandbox represents missing protected metadata paths such as `.git`
with empty read-only directories. Repository and project discovery treated any
`.git` directory as a checkout root, so this synthetic directory could hide a
real parent repository and its trust configuration.
## What changed
- Treat a `.git` directory as repository metadata only when it contains
`HEAD`, while continuing to recognize file-based `.git` entries.
- Protect missing `.git` paths with the same read-only synthetic mounts as
other workspace metadata without disrupting parent-repository discovery.
- Canonicalize and read-only bind the synthetic-mount registry into the
sandbox, and make protected-path cleanup handle read-only directory trees.
## Testing
Added coverage for repository, project-root, trust, synthetic-mount, and
Landlock behavior, including nested incomplete `.git` directories and a
redirected `TMPDIR`.
GitOrigin-RevId: 0724c54d56531143bb28011e4ca414cd3b0212be
## Why
Windows Terminal can discard rows scrolled through a partial DEC scroll region instead of retaining them in terminal scrollback.
## What changed
- Detect Windows Terminal, including via `WT_SESSION`, and use full-screen scrolling for inline viewport growth and history insertion.
- Keep the existing terminal-wrapped history behavior for Zellij while centralizing terminal-specific scrollback selection.
## Testing
Add VT100-backed tests covering strategy selection and preservation of scrollback during history insertion and viewport growth.
GitOrigin-RevId: 209a7a8053a1fcf911d6e0aee764e563b8725bd1
## What changed
- Initialize custom text prompts with the main composer's editor keybindings and Vim setting.
- Support Vim mode transitions, operator sequences, cursor styles, keymap contexts, and mode-aware footer hints in these prompts.
- Start Vim prompts in insert mode, use the first `Esc` to enter normal mode, and preserve `Esc` cancellation outside Vim.
## Testing
- Cover remapped editor and Vim commands, mode and context transitions, paste handling, cancellation, and footer rendering at different widths.
GitOrigin-RevId: 7a678310639dafb938084197df23d6d2a080a051
## What changed
- Ignore Guardian warning notifications that report a successful automatic approval review, keeping approved reviews out of TUI history.
- Continue displaying all other Guardian warnings.
- Extend the approved-review history test to cover the notification path.
GitOrigin-RevId: 719e84bc5b20c0a5364d10f84be9c6ac96158719
## Why
Paste placeholders and deferred slash-command parsing can hide the meaning of an input until it is expanded or a session is configured. Draining such input as an ordinary message can accidentally treat pasted text beginning with `!` as a shell command or lose `/plan` behavior.
## What changed
- Track paste-expanded inputs that begin with `!` as literal model input through history, queue editing, retries, and startup queues.
- Defer `/plan` parsing when session or model state is unavailable, then submit it in plan mode with shell escapes disabled.
- Drain queued input only after session configuration, and keep later queued prompts pending when an initial prompt cannot be submitted.
- Suppress queue auto-send before applying a replayed thread session so input from the outgoing thread is not submitted during restoration.
## Testing
Add coverage for direct, recalled, edited, interrupted, rejected, startup-queued, and plan-mode paste flows, including placeholder collisions and rejected initial images.
GitOrigin-RevId: d482220d8df21754f166fea5b54e9945f622a978
## Why
Bedrock sessions that use the AWS SDK credential chain need a way to recover when credentials expire during a request.
## What changed
- Add `aws.auth_refresh` provider configuration with an `aws` command, arguments, and a configurable timeout.
- Run the command for refreshable Bedrock authentication failures, reload the SDK credentials, re-sign the request, and retry it.
- Share refresh state across matching provider configurations so concurrent failures invoke the command only once. Bearer tokens, command auth, and static environment credentials do not use this recovery path.
## Testing
- Add coverage for configuration validation, refreshable error classification, concurrent refresh sharing, and an end-to-end retry signed with refreshed credentials.
GitOrigin-RevId: 0302fe3aabdbc1097e7bd62a74d407ba38a3cc57
## What changed
- Resolve duplicate exact-name matches to the most recent session instead of rejecting the queue request as ambiguous.
- Include non-interactive and custom-source sessions in name-based queue lookups.
- Prefer state database matches before falling back to rollout scanning.
## Testing
- Cover queueing to non-interactive and custom-source sessions, including duplicate names and a state database match that avoids importing a legacy rollout.
GitOrigin-RevId: 5b019da0a950c9381d324a09a21c78a9d0ac2252
## Why
Approval and item IDs can collide across concurrent threads. Tracking pending app-server approvals by ID alone can therefore resolve, submit, or dismiss a request from the wrong thread.
## What changed
- Key command execution, file change, and permissions approvals by both thread ID and approval ID.
- Route approval responses through the originating thread and require the thread to match when processing resolution notifications or dismissing approval prompts.
- Canonicalize parseable thread IDs so equivalent UUID representations still match.
## Testing
- Cover colliding approval IDs across threads, mismatched resolution notifications, prompt dismissal, and response routing for primary and background threads.
GitOrigin-RevId: c2d899a1e4b6a6413c78a0595a5311f5fabb9815
## What changed
- Recognize `edu_plus` and `edu_pro` as distinct education workspace plans across authentication, backend rate-limit mapping, and app-server account schemas.
- Include both plans in cloud configuration eligibility and use the education usage-limit behavior.
- Display the plans as `Edu Plus` and `Edu Pro` in the TUI status view.
## Testing
- Cover parsing, workspace classification, account and rate-limit responses, cloud configuration eligibility, usage-limit messages, and TUI display names for the new variants.
GitOrigin-RevId: bf8add780ae03a3c6d10c4f4afa0da262c37928e
## What changed
- Add an optional `delivery` field to agent message events and app-server
`agentMessage` items, with `"async"` identifying a user-visible message sent
without ending the current turn.
- Preserve the marker through legacy event conversion, thread history
materialization, replay, and generated JSON and TypeScript schemas.
- Require delivery of async agent message completion notifications on the
in-process app-server transport.
## Testing
- Cover preservation of async delivery metadata in thread history.
- Cover delivery-required classification for async agent messages.
GitOrigin-RevId: f92ba25de1293ee271404badfdf0d117d6530329
## What changed
- Include legacy managed-file and MDM settings when resolving project root markers and project trust in both canonical and executor-local config loads.
- Preserve the existing managed-layer precedence in the final config stack and resolve managed relative paths against the same bases used by the final loader.
- Update explicit-untrusted warnings to describe the effective configuration and direct users to an administrator when the setting is managed.
## Testing
- Cover managed root markers, managed trust overrides, MDM precedence, app-server config reads, and the remote TUI warning.
GitOrigin-RevId: 9b5ddd54b4530f73589d6842a15cbab7e6d6bbb9
## What changed
- Show a description and the destination paths affected by each file-change approval.
- Include both source and target paths for moves, format cross-platform paths for display, and show `unavailable` when change details are missing.
- Recover file changes from buffered events and thread snapshots so live and replayed approvals retain their destination details.
## Testing
- Add coverage for active and replayed approvals, moved and cross-platform paths, and the missing-destination fallback.
GitOrigin-RevId: 24f90b313fd8643f90cbead1504c788b140d7fed
## Why
When the app server reports a misalignment policy violation, the TUI must stop the affected chat rather than allow more work to continue in it.
## What changed
- Finalize the active turn, clear queued and draft input, disable the composer, and reject further operations and interactive requests for the stopped chat.
- Interrupt an active side conversation when its parent reports the violation, and prevent queued turns, forks, approvals, or goal resumption from restarting work.
- Show a non-dismissible precaution view that directs users to start a new chat or resume another one, with agent command center navigation for remote sessions.
## Testing
Added coverage for stopped-chat behavior, parent/side-thread handling, blocked goal resumption, navigation actions, and narrow and remote-session rendering.
GitOrigin-RevId: 0268c46a19294a17765ea4099f389f15ffaaf030
## Why
Compaction can remove the tool-call events that associate an MCP app widget with
the tool, account, and URI needed to authorize later resource reads.
## What changed
- Store a bounded MCP resource-origin checkpoint with each compacted rollout.
- Restore the checkpoint when resuming a session so existing widgets remain
readable after compaction and restart.
- Discard saved origins when rollback rewrites history across the compaction
boundary, and reject oversized or invalid checkpoints during restoration.
## Testing
- Extend the app-server MCP resource-origin test to compact a paginated thread,
continue the conversation, and read the original widgets before and after a
restart.
- Verify rollback clears provenance that no longer matches retained history.
GitOrigin-RevId: 7f91c6202fe8d9be21c78dda42fa205937c44263
## What changed
- Add the experimental `autoApprovalReview/strictReviewRequired` app-server notification with the review's `threadId`, `turnId`, and `startedAtMs`.
- Emit it when Guardian v2 leaves an approval review in progress because the action risk is elevated or its score is stale.
- Export the notification through the Rust, TypeScript, and JSON schema surfaces and route it to the associated thread.
## Testing
- Cover strict-review reason tracking for elevated and stale risk scores.
- Verify that high-risk approval routing emits one notification whose identifiers and timestamp match the review-started event.
GitOrigin-RevId: e65352894520bfb756c75b2c95e2e149f9767bb2
## What changed
- Add `tui.keymap.global.open_agents`, defaulting to `alt-a`, to open the shared agents overview.
- Add an `agents` keymap context for search, new task, rename, stop, and grouping actions.
- Expose the new actions in the keymap picker and render dashboard hints from the resolved bindings.
- Preserve existing custom `alt-a` bindings by disabling the new default when it would conflict.
## Testing
- Cover remapping, reserved keys, conflicts, and compatibility with existing bindings.
- Verify that configured dashboard shortcuts act on the selected filtered task.
GitOrigin-RevId: 98c48a332e06cb96dbf0e59647ce7959d45b9988
## Why
Some managed filesystem permission profiles cannot be represented by the
legacy app-server sandbox policy without changing which paths are accessible.
## What changed
- Require legacy sandbox conversion to preserve the filesystem policy's
semantics, and reject unsupported profiles with an actionable error.
- Keep queued follow-up messages and safety-buffered retries intact when
permissions are rejected, resuming queued input only after a compatible
profile is selected.
- Cover compatible profiles, lossy restrictions and write roots, turn-start
handling, and safety-buffered retries with regression tests.
GitOrigin-RevId: 345cc2a839206b2b1997e8981feb59f91b6975cc
## What changed
- Add `codex agents` to open the shared agents overview without creating a new session.
- Start the local background app server automatically on Unix, or connect to a server supplied with `--remote`.
- Reject invocation-specific session overrides that cannot apply to shared sessions.
- When the overview is opened from an embedded session, offer to start the background server without moving or interrupting the current session.
## Testing
- Cover command-line parsing and rejection of incompatible overrides.
- Snapshot the embedded-session background-server prompt.
GitOrigin-RevId: 60845dfebc48d820dc4ff090626d30452127f062
## What changed
- Let users start tasks, open root sessions, rename tasks, and stop active work directly from the agents overview.
- Show details for the selected task on wide terminals and limit the overview to root sessions while still reflecting background activity.
- Preserve draft input and pending server requests when switching sessions so running roots and their subagents can continue in the background.
- Apply the selected project's working directory when dispatching from project grouping, including remote workspaces.
## Testing
- Expand overview rendering and interaction coverage for root filtering, dispatch, search, selection, renaming, and responsive input.
- Cover switching away from roots with running subagents and retaining background server requests.
GitOrigin-RevId: b7b0d33b7ecc077498efb756a0ad2fd425158b17
## What changed
- Pass the screen size already available to TUI draw and history-tail paths into history insertion.
- Use the terminal's cached screen size for direct history insertion calls instead of querying the backend again.
- Extend the terminal size-query regression test to cover history insertion.
GitOrigin-RevId: 44c7a0f0bc5bc365d8d0c72d7e26587ed17a4821
## What changed
- Add `/agents` to open a full-screen dashboard of loaded root sessions from the shared app server, with subagent status reflected in each root session.
- Support search, navigation, and grouping sessions by project or status.
- Refresh the dashboard when relevant thread notifications arrive, while preserving its selection and view preferences.
- Show a clear message when the dashboard is unavailable with the embedded app server.
## Testing
- Add coverage for dashboard rendering, status grouping, persisted view state, and restoring the conversation viewport after closing the dashboard.
- Cover `/agents` command discovery and dispatch from parent-owned threads.
GitOrigin-RevId: 6651f4c47358116e1809da3ac8844a5842026a95
## What changed
- Add `codex queue --thread <THREAD> --message <TEXT>` to submit a text message through the `thread/queue/add` app-server API.
- Resolve active sessions by UUID or exact name across interactive, exec, and custom sources, and reject ambiguous names.
- Support local and explicit remote app servers while reporting incompatible servers and configuration overrides instead of silently changing the target.
- Reject empty messages and image attachments.
## Testing
- Add CLI coverage for remote submission, validation, unsupported servers, and local-daemon routing.
- Add session lookup and queue tests for stale, non-interactive, custom, and duplicate session names.
GitOrigin-RevId: 44c233f752b63a85c85b92fa6da303336e4ddeca
## What changed
- Use `/subagents` consistently for the subagent picker and status UI, removing the `/agent` alias.
- Rejoin already-loaded subagent threads without overriding their existing settings.
- Route notifications and approval requests only to the active thread or its known subagents, discard unrelated startup events, and avoid replaying resolved approvals.
## Testing
- Add coverage for filtering buffered startup events, dropping resolved approvals, preserving owned subagent approvals, and resuming threads without setting overrides.
GitOrigin-RevId: b4e597f7cd4756faccf31d8b964e7a172f5ab0eb
## Why
Filesystem permission paths can use a convention that differs from the host
running Codex. Converting them immediately to native absolute paths can change
the meaning of ambiguous paths such as `/C:/secret` or Windows UNC paths.
## What changed
- Store literal filesystem permission paths as `PathUri` values through the
runtime policy and execution protocol.
- Keep legacy string-based serialization at explicit protocol boundaries and
reject conversions that cannot be represented losslessly.
- Encode native paths as opaque URIs when a normal file URI would imply the
wrong path convention.
## Testing
Added coverage for cross-platform and ambiguous path round trips, UNC path
variants, permission-profile serialization, and deny-policy enforcement.
GitOrigin-RevId: 5247713796d1f2bb4e02f94eb9fc82d4698060f0
## What changed
- Query the remote app server for project config layers before starting a thread and show the trust prompt when the project has no existing decision.
- Resolve relative remote working directories and repository-root trust targets, then persist accepted trust through `config/batchWrite` on the remote server.
- Preserve existing trusted and untrusted decisions, including an untrusted repository that contains the requested working directory.
- Exit when the remote trust prompt is declined and ignore repeated key events in the trust selector.
## Testing
- Add coverage for remote trust detection, persistence, thread startup, existing decisions, nested untrusted projects, and rendering a remote Git subdirectory.
GitOrigin-RevId: e5fba2ea23bad1fb28f01df522cadbe05fcbb942
## Why
The per-thread replay buffer limited its event count, but streamed agent-message
deltas could still retain an unbounded amount of text while a thread was
inactive.
## What changed
- Coalesce adjacent deltas for the same thread, turn, and item into chunks of up
to 4 KiB.
- Limit buffered agent-message deltas to 256 KiB, discard a single delta larger
than that limit, and evict the oldest events when either buffer limit is
exceeded.
- Keep pending input and approval state in sync when eviction removes the
corresponding request, including clearing side-thread status indicators.
## Testing
Added coverage for delta coalescing, byte-based eviction, oversized deltas,
replaying only retained text, and side-thread status updates after eviction.

## Why
In-process app-server filesystem requests use typed protocol requests and do
not need JSON-RPC parameters.
## What changed
Pass remote filesystem parameters to `request_fs_path` as closures and
evaluate them only when the session uses a remote request handle.

## Why
The custom TUI buffer diff emitted `ClearToEnd` for unchanged trailing blank
regions, producing unnecessary terminal output.
## What changed
- Clear a row tail only when its cached contents changed or a wide glyph overlaps
the clear boundary.
- Keep blank cells marked `AlwaysUpdate` in the drawable region so viewport
invalidation still forces them to repaint.
- Preserve Ratatui's native cell diff behavior for the remaining updates.
## Testing
Add coverage for unchanged row tails, forced blank-cell updates, and shrinking
wide graphemes, including half-width katakana with combining marks.

## What changed
- Skip hyperlink layout for wrapped rows above the scroll offset and stop once
processing reaches the bottom of the viewport.
- Resolve each rendered link destination once while marking its visible cells.
- Add coverage for hyperlinks that span visible wrapped rows after scrolling.

## What changed
- Stop treating Vim normal-mode history-up as an alias for editing the latest queued message.
