## Why
`AbsolutePathBuf::relative_to_current_dir` previously read the current directory even for absolute paths, causing resolution to fail if the current directory had been deleted.
## What changed
Route absolute inputs through `from_absolute_path` without querying the current directory. Relative inputs continue to resolve against the current directory.
## Testing
Extend the Unix regression test to verify that `relative_to_current_dir` succeeds with a deleted current directory and produces the same normalized path as `from_absolute_path`.
GitOrigin-RevId: 6bc6cb43d9f4d57359639708c4d30524d89cfa92
## Why
The managed daemon writes an executable and Unix-style state beneath `CODEX_HOME`. Windows-mounted WSL filesystems (DrvFS/9p) do not reliably support the required permission semantics, which can cause startup to fail before the TUI opens.
## What changed
Detect WSL homes on 9p filesystems, checking an existing ancestor when `CODEX_HOME` does not yet exist. Keep the TUI in embedded mode instead of automatically starting the shared background server, and show a startup warning explaining the exclusion.
## Testing
Extend the daemon exclusion warning snapshot to cover the Windows-mounted WSL message.
GitOrigin-RevId: 995e6236d79d8190b0ab1e6b4761eeef3c068467
## Why
In `CodeModeOnly`, MCP resource helper definitions changed when the first server was added or the last server was removed.
## What changed
Always register `list_mcp_resources`, `list_mcp_resource_templates`, and `read_mcp_resource` in `CodeModeOnly`, even without configured MCP servers. This keeps their definitions stable across server configuration changes.
## Testing
Add a regression scenario that calls all three helpers before adding a server, with a server registered, and after removing it. Assert identical tool definitions across requests, empty resource and template lists, and the expected error when reading from an unknown server.
GitOrigin-RevId: c5777efac250b83dd4bb1c9100a6b6169470556f
## What changed
When `IncrementalTools` is enabled for Responses Lite, track tool definitions in world state and conversation history. Send the initial catalog once, then append only added or changed definitions while preserving earlier request history. Emit developer notices for removed tools and namespace instruction changes.
Use history-supplied definitions for normal requests and remote compaction, and omit empty `additional_tools` prefixes. Keep the existing tool delivery behavior for the Responses API and when the feature is disabled.
## Testing
Add unit and snapshot coverage for catalog and namespace transitions, empty catalogs, and stable hashing across JSON object key order. Add a request-history scenario covering unchanged tools, a model switch that changes one definition, persisted catalog hashes, and Responses API behavior.
GitOrigin-RevId: 76bde175973b81f8ad23873919da3c8ddcdf6065
## Why
Changing a deferred tool's output schema could add or remove the shared MCP type preamble from the `exec` description.
## What changed
Include the default or configured MCP TypeScript preamble whenever `code_mode_only` is enabled, regardless of the available tools' output schemas. Preserve an empty preamble override as a way to omit the section.
## Testing
Add a regression test that checks description stability when a deferred tool gains an MCP output schema, covering default, custom, and empty preambles. Update description expectations, request snapshots, and two Guardian context-budget test thresholds for the added preamble.
GitOrigin-RevId: 725035d6159e9da3c4beff5482c426c082e768b4
## Why
When `flush_transcript_tail_on_session_end` is enabled, remaining speech must be available in thread history as soon as realtime closure is reported, even while a model response is still running. Saving that transcript should not trigger another model request.
## What changed
Record the transcript tail directly in model and client history, attaching it to the active turn or creating a completed history turn when idle. Flush persistence before emitting `RealtimeConversationClosed`, and keep realtime context active until recording finishes so the return to text instructions follow the transcript.
## Testing
Extend core and app-server tests to cover immediate history visibility in paginated and legacy modes, idle and active turns, closure without extra inference, transcript reuse in subsequent text turns, and interruption after closure.
GitOrigin-RevId: ae323b711f22aa88db1432e24ad4bb3eb3f08f6b
## Why
Flattened notification settings prevent `serde_ignored` from detecting unknown keys in `[tui]`, allowing them to pass `--strict-config` validation.
## What changed
Detect unknown TUI keys by comparing configured keys with a serialized `Tui`, keeping accepted keys derived from the configuration type. Apply this check to config files and `-c`/`--config` overrides so keys such as `tui.bogus_key_xyz` produce an unknown-field error while valid notification settings remain accepted.
## Testing
Add regression coverage for unknown TUI keys, diagnostic source ranges, valid notification settings, and generic validation behavior. Extend CLI tests to cover TUI overrides and config validation before terminal checks.
GitOrigin-RevId: b04467523442183e7a54415d82c3f632f97ef319
## What changed
Add a scenario test and snapshot covering the request before remote `/compact`, the compaction request, the persisted replacement history, and the first subsequent user turn.
Capture the replacement history before the next turn can update its context, and assert that the compaction request contains one `compaction_trigger` and the next request includes the returned encrypted checkpoint.
GitOrigin-RevId: e22e12f16bdb11b1296e81a2e0ffd5f70e560ff6
## What changed
After successful Amazon Bedrock setup, check whether the configuration uses AWS GovCloud. If detected, show application configuration and security guidance with a terminal hyperlink and require an explicit Enter press to continue. Allow scrolling in short panes while keeping the acknowledgment visible.
Continue onboarding without the warning for non-GovCloud configurations, failed checks, or checks that exceed the 15-second timeout.
## Testing
Add snapshots and tests for the checking and warning screens, explicit acknowledgment, guidance hyperlinks, and scrolling in short panes, including a one-row content viewport.
GitOrigin-RevId: d5d0352af0a50b58e8b8feab5daf75fde428ece7
## What changed
Persist the service's last reported lifecycle reason and numeric HRESULT in the existing service registry key. Distinguish requested stops, shutdown, owner removal, startup failure, broker failure, and interrupted registration, and reset the record on startup. Recording is best-effort and does not affect the service lifecycle.
Emit `codex.windows_sandbox.service_stopped` when a provisioning client observes a stopped service, including the recorded reason, HRESULT, and Windows service exit codes. Recheck the service status and registry record before emitting to avoid pairing inconsistent evidence during a concurrent restart. The metric counts observations, not unique outages; the recorded reason is advisory.
Update the cached service status only after `SetServiceStatus` succeeds. Extract diagnostic error codes from typed errors without collecting error text or user data.
## Testing
Add a test covering Win32-to-HRESULT conversion, preservation of Windows HRESULTs through error context, and a zero fallback for untyped error text.
GitOrigin-RevId: d0d39d091410e2b5499a0803475804d12235f836
## Why
Archiving or deleting the selected task could make Command Center selection jump to the current task instead of a neighboring task in the displayed list.
## What changed
Choose the next surviving task in displayed order before removing tasks, falling back to the previous task when needed. Apply this selection behavior to archive, delete, and hide actions, respecting filtering and grouping.
Preserve the pending selection across view rebuilds, batched removals, and duplicate server notifications. Allow selection to fall back when a rename target disappears while retaining the existing notice about its unsubmitted title.
## Testing
Add regression tests and snapshots for archive/delete selection across project, status, and model grouping, with and without filtering. Cover removal of the attached task, external removal notifications, removal of a pending successor, repeated repaints, and an empty task list. Update the disappeared-rename-target snapshot to verify that the remaining selection is preserved.
GitOrigin-RevId: ca93d664fadbc602993fbdae316c7a375b449345
## What changed
Render confirmation dialogs as centered overlays while preserving the composer or parent picker behind them. Share dialog sizing and cursor placement across stacked views and full transcript rendering, with input still routed exclusively to the active dialog.
Use the shared confirmation preset for prompts including full access, session archive/delete, goal changes, and log upload consent.
## Testing
Add coverage for backdrop retention and cursor routing at multiple terminal sizes, and for preserving the compact viewport and composer draft after dismissing a confirmation without replaying history. Update confirmation snapshots to show the retained backdrop.
GitOrigin-RevId: 026af89904ec345e2b330317b8cc844512125d0e
## Why
Accepting a Find result must not let a held `Enter` submit the composer draft, including when terminals report repeated keys as fresh presses.
## What changed
- Make `Enter` accept the displayed result for reading, while `Ctrl+P` and `Ctrl+N` navigate older and newer matches.
- Make `Escape` cancel query editing and restore the pre-search presentation; after acceptance, it returns to the latest transcript content.
- Consume unmodified `Enter` while reading a result, but let modified `Enter` reach configured composer bindings.
- Update footer hints to show acceptance, cancellation, and the active Find state.
## Testing
Extend input-routing coverage for repeated `Enter` presses and modified composer bindings. Update search tests and footer snapshots for acceptance, cancellation, and result navigation.
GitOrigin-RevId: 2a2b7c389240ffa941e3623d7fb7d877455fa9a5
## Why
Daemon updates discard installer stderr, leaving failed installs with only an exit status and no installer diagnostics.
## What changed
Capture the last 2 KiB of installer stderr and append it to errors when the installer exits unsuccessfully. Drain stderr concurrently and wait at most one second after failure so subprocesses holding the pipe open cannot delay error reporting indefinitely. Keep captured details within the manual update response limit, and configure PowerShell output as UTF-8 to preserve non-ASCII diagnostics.
## Testing
Add coverage for stderr tail truncation, bounded draining when a subprocess keeps stderr open, and manual update responses containing heavily escaped diagnostics. Extend the Windows installer test to check non-ASCII error text.
GitOrigin-RevId: d0da19b233006f97770d3f7f5f057e5e98fd2913
## Why
Registration-only refreshes retain the existing sandbox, so package maintenance should not require another cloud-policy fetch.
## What changed
Skip managed configuration loading when a provisioning request has both `registered_core` and `refresh_only` set. The registered-runtime transaction still checks the existing owner, accounts, and unchanged settings under the setup lock. Other provisioning requests continue to enforce managed policy.
## Testing
Update the invalid-impersonation-token test to cover all four flag combinations, verifying that only registered refreshes succeed without loading configuration.
GitOrigin-RevId: e65ba1359be65e6314fa483b24fb66ed57a444ac
## What changed
Remove the fixed 64 KiB output cap from `WorkspaceCommand` and send
`output_bytes_cap: None` in `command/exec` requests so bounded commands use
the app-server default. Preserve `disable_output_cap` for commands that need
uncapped output, including Git diffs.
GitOrigin-RevId: 6f2ed0d127d9ff2317670851894ae4988f7c7508
## Why
Bedrock catalogs cleared all service-tier metadata, and requests omitted every selected tier. This prevented users from selecting `ultrafast` or using tiers defined in custom catalogs.
## What changed
- Advertise `ultrafast` for `openai.gpt-6-astra` on Mantle and the `global.openai.gpt-6-astra` and `us.openai.gpt-6-astra` Runtime variants, while retaining the implicit default tier unless users select otherwise.
- Preserve custom catalog speed tiers, service-tier definitions, and defaults while continuing to normalize Bedrock web search compatibility.
- Send selected service tiers only when the Bedrock model advertises them, including `flex`.
## Testing
Add coverage for `model/list` tier discovery, custom catalog preservation, configured and per-turn HTTP request tiers, and TUI slash-command selection, toggling, and model switching.
GitOrigin-RevId: 4793e7af7b9f604a6b7812611030da6adb8acd35
## Why
Truncating the preview alone can leave the serialized MCP tool result above its byte budget because JSON escaping and the result wrapper add bytes.
## What changed
Measure the complete serialized replacement and progressively reduce the preview budget until the result fits or the preview is empty.
## Testing
Strengthen the regression test with quotes, backslashes, and newlines. Assert that the serialized result fits within the 1,024-byte budget and that truncating it again returns the existing result unchanged.
GitOrigin-RevId: ebd97b1a6ca71343941a96e472cb313028ac680c
## Why
Copying rendered transcript selections added Markdown formatting and escapes to the plain-text clipboard payload. Selecting bold text such as `hello` could paste as `**hello**`.
## What changed
Separate the literal selection text from the Markdown source used to render clipboard HTML. Plain-text copies omit inline formatting delimiters, added code fences, and Markdown escapes while retaining list and table structure. Rich-text pastes continue to preserve formatting through HTML.
## Testing
Update clipboard and transcript selection tests to verify literal text alongside rich HTML, including lists, inline code, paths with Markdown punctuation, hard breaks, streamed code blocks, and tables across layout widths.
GitOrigin-RevId: 980ee2ed0b0e201b581a3a301fa04d796c65af2e
## Why
Remote executors need to recover from confirmed authentication-service outages and spread reconnect attempts after a shared outage. Registration retries must remain limited to confirmed failures before a write, since replaying an ambiguous request can replace a newer registration.
## What changed
- Retry registry responses with HTTP 502 and `authentication_service_unavailable`, alongside the existing HTTP 503 `registration_conflict` retries.
- Accept structured registry errors in `detail`, keeping the canonical `error` authoritative when both are present.
- Randomize reconnect delays between half and all of the current exponential backoff, retaining the 30-second cap.
## Testing
Add coverage for reconnect jitter bounds, authentication-outage retry cancellation, error-envelope precedence, and preservation of Noise identity and initialized sessions across retries. Make the HTTP-header helper cleanup test wait for the helper PID before cancellation and verify process termination when the provider is dropped.
GitOrigin-RevId: 35fdb57732d17b0bbfeca8a4dc557a0988e29a31
Register `incremental_tools` as an under-development feature that is disabled by default, and expose it in the configuration schema for top-level and profile feature settings.
GitOrigin-RevId: 9579822c745e9fce598085bdc5ef8da6aabb06d7
## Why
Delegated turns can begin without a user message, leaving threads without a task preview. Populate the preview from delegated input so these threads are discoverable before a user follow-up.
## What changed
- Extract previews from completed `create_thread` and `send_message_to_thread` outputs in the `codex_app` and `codex_tui` namespaces.
- Unwrap recognized `<codex_delegation>` inputs and decode their escaped task text for display, preserving model content. Keep plain or unrecognized wrappers as text and ignore blank inputs.
- Fill missing previews in state metadata extraction and live thread metadata updates without replacing existing previews or setting the title or `first_user_message`.
## Testing
Add tests for delegation decoding and tool filtering, preview-only metadata updates, preservation of later user-message metadata, and database listing before a user follow-up in both legacy and paginated history modes.
GitOrigin-RevId: f7b3c60ef75e08c76b4084d043e3967bf2bade22
## What changed
Allow Responses-compatible providers to configure live web access and remote compaction under `model_providers.<id>.capabilities`:
```toml
[model_providers.custom.capabilities]
external_web_access = false
remote_compaction = "v2"
```
`external_web_access = false` keeps hosted web search from accessing the live web. `remote_compaction` accepts `v2` to send `compaction_trigger` items through the Responses endpoint, or `unsupported` to use local compaction. Omitted capabilities retain existing provider defaults.
## Testing
Add unit coverage for preserving unspecified defaults and a request-snapshot scenario verifying cached web search and V2 compaction for a custom provider.
GitOrigin-RevId: fbcc4870aa51c112af575d711679a3941d1e7878
## Why
Paginated thread history can persist large MCP results in completed tool-call items. Bound these stored results to avoid retaining multi-megabyte payloads.
## What changed
Apply a 64 KiB preview budget when persisting oversized MCP results in paginated history. Replace the result with a truncated text preview of its serialized JSON, preserving `is_error` and clearing `structuredContent` and `_meta`. Leave small results unchanged.
Share the truncation helper with the existing MCP tool-call event path.
## Testing
Add helper tests for unchanged small results and oversized results with structured content and metadata. Add a thread-history test verifying that persisted MCP results contain a bounded preview with the beginning, end, and truncation marker while preserving tool arguments.
GitOrigin-RevId: 09dce73c70bfd357c9b9630f456e9e5c1d8492cf
## What changed
- Record original and persisted item sizes in `codex.rollout.persistence.item_bytes_v2`, distinguished by stage, and record positive size reductions in `codex.rollout.persistence.bytes_removed`. Count the full original size as removed for dropped items.
- Use explicit histogram boundaries from 1 KiB to 64 MiB for item sizes, bytes removed, and `codex.rollout.persistence.turn_bytes_v2`. Larger values remain represented in the overflow bucket and histogram sum.
- Align item and turn size stages and report a measurement error when a kept item's persisted size cannot be measured.
GitOrigin-RevId: 6487acf1c6f2c041ab9680ab398491d3c1541388
## What changed
- Remove `namespace_tools` from `ProviderCapabilities` and `namespaceTools` from `ModelProviderCapabilitiesReadResponse`, updating generated schemas and SDK types.
- Preserve tool namespaces and configured collaboration tool namespaces without a provider capability check, and always use Responses Lite tool serialization for Responses Lite requests.
- Gate tool search on `supports_search_tool` and retain the existing image generation and web search checks without requiring a namespace capability.
GitOrigin-RevId: ae1843563736765a40e03a02c41ff5e470018a93
## What changed
- Combine file-backed rollouts and buffered rollout prefixes into `rollouts.tar.gz`, keeping diagnostics as separate attachments.
- Bound the archive and its upload envelope by the existing size limit, skip invalid or duplicate archive filenames, and fall back to individual rollout attachments if archiving fails.
- Add `rollout_archive_filename` to the report thread index so rollout filenames identify archive entries or fallback attachments.
## Testing
Add an upload test that extracts the archive and verifies the filenames and contents of both a compressed file-backed rollout and a buffered rollout. Update the thread index test to check the archive filename.
GitOrigin-RevId: 973da6eec2249b04ef7992b5e1e4fd27f044b80f
## What changed
Strengthen `tool_call_timing_guard_ignores_code_mode_source` to capture tracing output and assert that direct and nested code-mode calls together emit exactly one `codex.tool_call` event. Disable ANSI formatting and keep callsite interest independent of untraced parallel test threads.
GitOrigin-RevId: cbf0c9bf6d4e5a72b6a1eb08e6aac43e257f2dcb
## Why
Tokio's paused clock can auto-advance while tests await the V8 thread. The service tests need explicit control over time when checking yield limits and grace periods.
## What changed
- Hold virtual time with a blocking-task guard that is released when dropped.
- Replace bounded polling loops with tool-start notifications and direct awaits of response tasks.
- Return an error from the test helper if the cell closes before a nested tool starts.
## Testing
Add tests covering tool-start acknowledgement when a cell throws or is terminated before invoking a nested tool, including assertions on the resulting cell responses.
GitOrigin-RevId: c221c0501ec0354052102c0211cc651008babff3
## What changed
Add optional `native_usage_usd_micros` fields to thread usage totals and breakdown groups, and carry backend values through the client alongside existing credit and USD estimates. Missing or null native amounts remain `None`, while explicit zero amounts remain `Some(0)`.
## Testing
Add coverage for native totals and group amounts, mixed batches with legacy responses, and the distinction between missing, null, and zero native group amounts.
GitOrigin-RevId: 53891fc95807138e2eccb99d4cda1520b857dba4
## Why
World-state sections could return only a single optional text fragment, with message separation controlled by the fragment itself. They could not contribute explicit `ResponseItem` values alongside instructions.
## What changed
- Let sections return ordered `WorldStateUpdate` values containing fragments or response items, with `Prefix`, `Standalone`, or `Mergeable` placement.
- Preserve explicit item boundaries when grouping context updates, and place prefix updates first when assembling initial context.
- Move standalone-message decisions from fragments to world-state updates and retain snapshot handling.
## Testing
Add tests for mixed fragment/item ordering, role and standalone boundaries, initial-context prefix placement, and snapshot restoration without repeated updates.
GitOrigin-RevId: c2514c3c98538da83f5140c10a9d89f531de6549
## What changed
Add `codex sandbox uninstall` to remove machine-wide legacy Windows sandbox accounts and network rules with administrator privileges. Run cleanup without loading configuration, preserving Codex home, sandbox directories, and filesystem permissions. Reject the command on other platforms.
Keep commands after `--` forwarded to the sandbox, including `codex sandbox -- uninstall --help`.
## Testing
Add parsing coverage for the uninstall subcommand and command separator. Add an integration test verifying that help and invalid arguments work with malformed configuration and leave configuration and credentials unchanged.
GitOrigin-RevId: d2b02ef7bc0a05742dd5eb3c47292ad517d46664
## Why
`additional_tools` response items were excluded from rollout persistence, dropping their tool definitions from saved history.
## What changed
- Persist `additional_tools` items in both legacy and paginated history modes.
- Expose the variant in generated JSON schemas, TypeScript types, and Python models, with an optional `id`, a `role`, and arbitrary JSON tool definitions.
## Testing
Add a recorder round-trip test that verifies tool definitions survive recording and loading in both history modes without parse errors.
GitOrigin-RevId: 0e7c7b1c10401ec6513fb744de642a1cf9e461d7
## What changed
- Make `/copy` select the latest completed response directly in the owned transcript. Navigate user messages, code blocks, and blockquotes with arrow keys or `j`/`k`, use `g`/`G` to jump to the ends, and press Enter to copy or Escape to close.
- Highlight selected blocks and keep surrounding context visible during navigation and resizing. Preserve source payloads for code and quotes, including rendered Mermaid diagrams and fenced Markdown tables.
- Pause queued submissions until copy mode closes, and report clipboard results in the transcript footer.
## Testing
Add tests for copy routing, keyboard navigation, highlighting and resize behavior, source whitespace and line endings, clipboard completion, and queued-input resumption.
GitOrigin-RevId: bd4f58ec17568f95d0e91014e5ddba33ca8bd57c
## What changed
Allow accounts using an API key with the OpenAI provider to access `/daybreak` and Daybreak policy notices. Model availability and the connected server still determine program access.
Use the same eligibility checks for turn submission, continuation, and retries. For API-key accounts, send the selected `cyberAccessProgram` when Daybreak is enabled and omit it when Daybreak is off.
## Testing
Extend session lifecycle coverage to check API-key turn parameters with Daybreak enabled and disabled. Add an API-key `/daybreak` help snapshot and update the signed-out error snapshot.
GitOrigin-RevId: ab6d4313c430f316ef9835d4facb878aab0b9725
## What changed
Keep Markdown link destinations attached to prompt and last-message previews in the agents overview details pane as text wraps and is clipped. Render visible links as terminal hyperlinks, while keeping truncation ellipses unlinked.
## Testing
Add a regression test and snapshot covering links that span multiple rows, prompt links, and clipped previews with unlinked ellipses.
GitOrigin-RevId: d121e062b197790ce45a70d6d64aadcb181e4dde
## Why
Paginated history previously persisted completed commands' full `aggregated_output`, allowing large command outputs to inflate stored history.
## What changed
- Limit persisted command `aggregated_output` to 64 KiB, including a truncation marker. Preserve the beginning and end of the output without splitting UTF-8 characters.
- Apply the shared persistence policy to rollout recording, thread-store appends, and legacy-to-paginated history migration.
- Measure persisted payload bytes after truncation so persistence metrics reflect the stored representation.
## Testing
Add coverage for the byte limit, UTF-8 boundaries, unchanged inputs that fit, and markers that exceed the budget. Verify capped output in paginated thread history and migrated legacy history, and verify persistence metrics use the truncated payload size.
GitOrigin-RevId: 01d420d396ad34b42dc5dc208c0bf88d890639ee
## Why
Streamed `response.failed` events can carry retry advice in `response.error.headers`. Ignoring it loses server-provided delays or uses a conflicting delay from a rate-limit message.
## What changed
- Parse nested `Retry-After` headers using the existing HTTP header validation and retry parser, and preserve them for rate-limit, overload, and generic retryable failures.
- Prefer valid headers over rate-limit message advice, falling back to the message when the header is absent or invalid. Keep terminal error classifications unchanged.
- Reject unrepresentable plaintext retry durations without panicking.
## Testing
Add regression coverage for header precedence, validation, and terminal errors, plus retry-loop coverage for SSE sampling, remote compaction, and WebSocket failures.
GitOrigin-RevId: 46433c2e9e6d5e804211ef96950fadd70e322b49
## What changed
Label the `/new` and `/fork` picker options “Use current Git worktree” and “Create new Git worktree”. Explain that creating a worktree makes a separate checkout of the repository in another directory.
## Testing
Update picker assertions and snapshots for both commands to cover the revised labels and description.
GitOrigin-RevId: b7fb1aac3107e39c324707f9ae69c210a97346d7
## What changed
- Remove `stdout`, `stderr`, and `formatted_output` from `CommandExecutionItem` and `ExecCommandEndEvent`, retaining `aggregated_output` as the output field.
- Update command event producers, legacy conversion, rollout traces, and the precomputed schema. Use aggregated output for terminal trace results.
- Clear `interaction_input` in emitted and migrated command completion items.
## Testing
Update command execution and trace tests to use aggregated output, and assert that legacy rollout migration preserves `aggregatedOutput`.
GitOrigin-RevId: ed59827d4a5ec9a767084ee4feac72c2042440f2
## Why
Transcript scrolling hardcoded `PageUp` and `PageDown` to full-page movement, ignoring customized pager bindings.
## What changed
Resolve unmodified `PageUp` and `PageDown` through the pager's scroll bindings so they can scroll by a full page, half a page, or one row, or remain unbound. Preserve the one-row overlap for full-page scrolling and leave pager typing shortcuts unhandled by the transcript.
## Testing
Add a regression test and snapshot covering default, half-page, single-row, and unbound configurations. Verify that `PageDown` reverses `PageUp` scrolling and that `j` and `Ctrl+u` remain unhandled.
GitOrigin-RevId: 945e99d7370f84f326ab71037be2924dddada32c
## Why
Transcript selection can consume a configured composer shortcut such as `ctrl-space`, preventing it from submitting a prompt or steering a running turn.
## What changed
Let explicitly configured shortcuts for active actions take precedence over transcript key handling when no transcript interaction is active. Include global binding fallbacks, while preserving empty `Enter` returning to the latest transcript content and default `PageUp` scrolling.
## Testing
Add regression coverage for `ctrl-space` submission with idle and running turns, default `PageUp` scrolling, and empty `Enter` returning to latest with composer or global submit bindings.
GitOrigin-RevId: 16613043a7634b47fd24e4ee9feacdce94a9fabd
## Why
If required MCP startup outlasts the requesting connection's cleanup, the newly created thread can remain loaded without subscribers because its listener is never started.
## What changed
Start the thread listener even when the requesting connection has already closed, allowing normal idle unloading to clean up the thread while preserving the `ConnectionClosed` result.
## Testing
Add a regression test that disconnects during blocked required MCP startup, then releases startup and verifies a `thread/closed` notification, an empty `thread/loaded/list`, and MCP process exit on Unix.
GitOrigin-RevId: 4ad912a82177266316042d806f5faa1713a48fa4
## Why
GNU Screen truncates Unicode in OSC titles to a byte, which can turn visible characters into control bytes and spill title text into the terminal.
## What changed
Detect Screen through `STY` and convert the full terminal title to printable ASCII. Map activity spinners and the status dot to ASCII equivalents, and replace other non-ASCII content with `?`. Keep Unicode titles outside Screen and preserve Unicode in TUI status rendering.
## Testing
Add coverage for ASCII title output with activity indicators and Unicode names, preserved Unicode outside Screen, and removal of control and invisible formatting characters.
GitOrigin-RevId: e6b45b9be0d06ab3c3eece89885647f3e9db17da
## What changed
Remove `initial_messages` from `SessionConfiguredEvent` and the corresponding schema. Stop attaching replay history to startup events for resumed or rejoined threads, and remove `InitialHistory::get_event_msgs`.
## Testing
Update the MCP resume test to verify persisted tool events through `load_history`, and retain coverage that resumed requests include prior conversation items.
GitOrigin-RevId: 54b72bc44423c9b1ef2051891ef392c0ede32fe5
## Why
Hook system messages were rendered as plain text, leaving ANSI formatting uninterpreted.
## What changed
Parse hook system messages into styled spans so colors and text styles render across lines. Preserve hook prefixes, continuation indentation, and trailing blank lines.
## Testing
Add a snapshot test for multiline ANSI styling and style resets, and extend multiline coverage to include a combining character and a trailing newline.

registered legacy config key. This avoids recursively visiting unrelated
subtrees while preserving alias normalization along matching paths.

## Why
Closed WebSocket connections previously triggered immediate reconnects, and successful handshakes reset backoff even when connections were short-lived.
## What changed
- Delay automatic reconnects before token refresh or enrollment, and report `Connecting` while waiting.
- Use exponential backoff with jitter between half and all of the delay, starting at 5 seconds and capped at 30 seconds.
- Retain backoff across short-lived connections and reset it after a connection lasts at least 60 seconds.
- Interrupt the reconnect delay on shutdown, auth owner invalidation, or enable/disable changes, including an immediate disable/enable pair.
## Testing
Add connection tests for delayed token refresh, backoff retention and reset, explicit re-enabling, and prompt shutdown. Update retry tests to check jitter bounds, saturation during sustained failures, and backoff retention after a successful handshake.

## Why
Cached subagents can remain in the TUI picker after being archived, including when archive notifications are missed.
## What changed
- Hide archived threads from the picker and keyboard navigation, and restore them when unarchived.
- Refresh both active and archived descendants to reconcile cached visibility, including after dropped server events. Queue a follow-up refresh when needed and preserve visibility changes received during an in-flight refresh.
- Preserve picker selection by thread ID as visible rows change, and mark archived thread attachments as replay-only.
## Testing
Extend regression coverage for missed archives, unarchive notifications, hidden subagent navigation, and the subagent enable prompt when only archived subagents are cached.

## What changed
Add an MCP integration test that forwards sandbox state from tool-call metadata unchanged to `codex sandbox --sandbox-state-json` and runs a real subprocess.
Verify that workspace writes succeed, overwriting an existing file outside the workspace fails and preserves its contents, and relative paths resolve against `sandboxCwd` rather than the MCP server's working directory.
