## What changed
- Handle `TurnModerationMetadata` for the active turn, showing a temporary block notice while an explanation is pending.
- Validate safety recourse metadata and render topic-specific explanations with safer ways to continue for biological and cybersecurity policy blocks. Apply the explanation only when the terminal policy error matches its domain; otherwise retain the existing error handling.
- Queue input while recourse is pending and preserve prepared images when queued messages are submitted.
## Testing
Add an integration test covering biological and cybersecurity blocks, the loading notice, and fallback for a mismatched policy error, plus a snapshot of the cybersecurity explanation. Extend queued-image coverage to verify submission succeeds after the original image file is removed.

## Why
Contention on the writer coordination lock can block writer cleanup indefinitely, preventing idle threads from unloading.
## What changed
Retry coordination lock acquisition every 50 ms and return `io::ErrorKind::TimedOut` after 30 seconds of contention. This lets cleanup release writer ownership and idle unloading finish even while another process holds coordination.
## Testing
Extend writer lock coverage to check the timeout error. Update the idle unload regression test to verify that the thread closes while coordination remains locked and can resume with its persisted turn after the lock is released.
GitOrigin-RevId: 513117fdaf3890283e7acdd149ce9abb66075b63
## Why
The process-local mutex cannot coordinate session name appends and removals from multiple Codex processes sharing the same home directory.
## What changed
- Guard index mutations with a persistent `session_index.jsonl.lock` file, retaining the lock until the blocking worker finishes even if its caller is cancelled.
- Return a timeout error after 30 seconds of lock contention without modifying the index.
- Rewrite removals through a unique temporary file while preserving index permissions, and skip removal when the index is absent.
## Testing
Update regression tests to check lock retention after cancellation, timeout without writing, successful writes after contention clears, and removal with a missing home directory. Retain coverage for cancelled queued updates preserving the next write.
GitOrigin-RevId: 5231c9ff85c6b34de5ee92931d119b6f46bd583b
## Why
`codex migrate-nfs-db` reported a successful migration when the database directory existed but contained no databases.
## What changed
Count databases that were migrated or already use DELETE journal mode. If none are found, print `No databases found.` instead of the migration success message.
## Testing
Extend the CLI integration test to cover an empty directory, a failure on a corrupt logs database after an earlier conversion, and a successful rerun that recognizes the converted database as already in DELETE mode.
GitOrigin-RevId: 16b109645925164f3af5d35a909417872cfa004f
## Why
MXC's `normalize_object_conflicts` can reject otherwise usable Windows policies when a network share does not support `FileIdInfo` or a protected deny path cannot be opened for metadata.
## What changed
Remove object-conflict normalization before and after volume-root expansion. Send explicit path grants directly to BaseContainer, which enforces path and symlink/junction alias precedence.
Document the resulting limitations:
- Hard-link names retain independent permissions, so an allowed name can access the same file through a less restrictive grant.
- Volume roots expand using their declared access without first reconciling aliases. A writable root can therefore generate more-specific writable grants that override a read-only root alias.
GitOrigin-RevId: de0b2d7b5b98eaa358a97156c02e9f7f85860335
## Why
The npm wrapper can exit successfully after its native child is terminated by a signal if Node ignores the re-emitted signal or a forwarding handler intercepts it.
## What changed
Set a fallback exit status of `128 + signal number` and remove listeners for the terminating signal before re-emitting it, preserving signal termination where supported.
## Testing
Add a non-Windows integration test using a built Codex binary to cover numeric argument-error exits, forwarded `SIGHUP` termination, and the fallback exit status for `SIGXFSZ`, which Node ignores by default.
GitOrigin-RevId: cad18a47aa50fd78517c367f8d8aae83bbbf7843
## What changed
Split saved-thread resume into preparation and activation. Preparation resolves configuration and attaches to the destination thread before activation replaces the displayed conversation.
Keep stored-backend configuration and local settings separate from active settings during preparation, while retaining the existing eager settings refresh for active-backend resumes. Use the destination backend for working-directory, permission, and directory-trust checks.
Carry the backend identity in the prepared result and reject activation through a different backend before changing the active conversation or composer.
## Testing
Extend coverage for preserving active settings and composer drafts during preparation, rejecting activation through another backend, applying destination remote-permission checks, and retaining active-backend settings refresh behavior.
GitOrigin-RevId: 7171f1abcf4bdd62793c21232a8b895bb809cf70
## What changed
Add optional `approvals.granular` catalog fields for the policy introduction and prompted and rejected category lists. Preserve template strings verbatim in `GranularApprovalMessages`, leaving validation and rendering to consumers.
Document the 500-byte template limit, required `{{ policy }}` and `{{ categories }}` markers, and fallback rules.
## Testing
Extend serialization tests to cover null, empty, and populated granular templates, and verify their preservation through model responses and base instruction overrides.
GitOrigin-RevId: ce32e41a9b37e2e7c45ac9b079708a640c99326c
## What changed
Add the `features.simplified_selection_hints` flag, disabled by default. When enabled, replace detailed plugin capability instructions with a concise developer message identifying the selected plugin and directing the model to use its available skills and tools.
Continue omitting hints for plugins without available capabilities and bounding hint length. Preserve the existing detailed instructions when the flag is disabled.
## Testing
Cover plugin refresh in an existing thread with the flag enabled and disabled. Verify that explicit skill prompts precede the simplified plugin hint and that the hint uses the developer role.
GitOrigin-RevId: 64fc3347bd49fffe675f343a4733ced1b4e5e88c
## Why
A subagent failure ends its work without requiring user action, but the agent command center treated it as needing attention and promoted its parent task into the `Needs you` group.
## What changed
Classify failed subagents as inactive when computing task groups and selecting details. Recognize subagents by either a parent thread or a subagent session source, including background workers without a parent.
Keep approval and user-input requests from descendants actionable, even beneath a failed agent. Show these requests as `Needs input` rather than `Error` when the displayed task is a failed subagent. Errors in non-subagent tasks continue to require attention.
## Testing
Add and update regression tests and a snapshot covering stable ordering after subagent failures, idle parents staying ready, failed background workers, and pending requests beneath failed agents.
GitOrigin-RevId: 1a06d5d00c08bb77c9ed36aadffd5e0514f0b2c6
## Why
Rust formatting should include source files that Cargo cannot discover, while keeping command lines within Windows limits.
## What changed
- Update `scripts/format.py` to discover tracked and non-ignored untracked Rust files with Git and invoke `rustfmt` in batches of 64 files. Use the workspace configuration and skip recursive child-module formatting.
- Pass `SystemDrive` and `LOCALAPPDATA` to Windows Bazel tests.
- Extend the spelling allowlist, remove a manifest feature exception, and clean up an unused import, an empty MCP scenario module, and its snapshot.
GitOrigin-RevId: c0d625fda9290ead6a63919325d65f7352abfa40
## What changed
Allow omitting `gateway_oauth.delivery` to send the gateway token as `Authorization: Bearer …`. Custom headers and cookies remain available when a provider also needs its own credentials.
Reject conflicting provider authentication and duplicate delivery headers with actionable errors. For gateway bearer delivery, require `model_catalog_url` to share the scheme, host, and port of `base_url`. Consistently reject request header collisions across auth application methods.
## Testing
Add coverage for omitted delivery, provider credential conflicts, and model catalog origin validation. Update inference tests to verify gateway-only authentication while signed in and combined ChatGPT and gateway credentials in separate headers.
GitOrigin-RevId: 8564d3998511b3f6c55f3b65a01ed9056a90417e
## Why
Tool calls can emit multiple outputs, and compaction can trim output content while retaining the same call and item IDs. The trace reducer rejected these versions as conflicting content. Late tool and code-cell events could also link outputs in map-key order instead of conversation order.
## What changed
- Preserve distinct tool output versions while retaining consistency checks for tool invocations.
- Link tool and code-cell outputs in thread history order, and resolve pending code cells after the entire event has been reduced.
- Prevent snapshot reconciliation from reusing the same conversation item twice when identical items move within history.
## Testing
Extend reducer regression tests for trimmed outputs, changed images and metadata, reordered identical messages, and late tool and code-cell events spanning the item-ID ordering boundary.
GitOrigin-RevId: eb4242d6a2d32d61c3caab9d3cc3cf6b374ce799
## Why
When workspace discovery receives a 401 and token refresh is permanently rejected, the generic discovery error hides the guidance to sign in again.
## What changed
Propagate cached permanent refresh-token failures for the current credentials through workspace routing and model-provider resolution as `CodexErr::RefreshTokenFailed`. Preserve account-change checks and only surface the cached rejection when external authentication is absent and the auth generation is unchanged.
## Testing
Add an app-server regression test that simulates `refresh_token_reused` during workspace discovery and verifies that the turn fails with `Unauthorized` and tells the user to sign in again.
GitOrigin-RevId: cf89c71fd6a2103e56d637838b0cb34d58b3cc32
## What changed
Collect original retained instructions, assistant context, and verified answers before applying synchronous request limits in `guardian-context` preparation. Carry original record sizes through collection, preserving whole-record omission notices, source ordering, and host assistant-context framing.
Apply retained transcript source size checks during synchronous transcript preparation as well.
## Testing
Extend regression assertions for synchronous/asynchronous retained-context parity and equivalent verified-answer omissions when oversized records are filtered during preparation.
GitOrigin-RevId: 9042ee3fe60ebd455f6656b4008efb2acc44ac3d
## What changed
- Move plugin install and uninstall errors and telemetry classification helpers into `codex-rs/core-plugins/src/manager_errors.rs`, preserving the existing public re-exports and error classifications.
- Box the realtime text routing future to bound the handoff future's size while retaining the admission permit across the await.
GitOrigin-RevId: ccf0c3bb93a8c69a0a618b96cd1525da87003176
## What changed
- Add `gpt-6.1-terra` to the bundled catalog and GCP Vertex model picker.
- Add `openai.gpt-6.1-terra` to Amazon Bedrock catalogs, including Global and US cross-region runtime variants.
- Use `gpt-6.1-terra` as GCP's preferred memory consolidation model.
## Testing
Extend catalog, model picker, thread startup, and Vertex request tests to cover GPT-6.1 Terra.
GitOrigin-RevId: edb3be3c4286c191349cdee742005ed3c67029e8
## Why
Async question replies appeared as plain user text, leaving Markdown formatting literal and repeating the full question above each answer.
## What changed
- Accent question titles with a `?` prefix while preserving Markdown in titles and suggestions.
- Render replies with a `↪ Re:` question caption and a Markdown answer. Limit captions to two rows with an ellipsis on overflow, while keeping answers complete.
- Apply the same rendering to live messages and loaded transcripts, preserving inline styles, hyperlinks, and Markdown when copying selections.
## Testing
Add snapshots and assertions for matching live and loaded transcript rendering, plus tests for caption clipping, hyperlink bounds, Markdown copying, partial selections, and whitespace-only or nonprinting answers.
GitOrigin-RevId: 0290d8a2ebfb42bd5d7374c7037cde5ae8a13b5d
## What changed
Replace `UserHistoryCell`'s `spoken` boolean with `UserMessagePresentation`, defaulting to `Plain` and using `Spoken` for speech transcripts. Route rendering checks through `is_spoken()`, preserving the existing prompt styling and whitespace handling.
GitOrigin-RevId: d0683a2b536a7d71f68fd9a089e6839d0ab0cc65
## What changed
- Add `codex-plugin-host` to launch a helper with a cleared environment, verify its readiness handshake, and expose framed stdin/stdout pipes with a 256 KiB frame limit and write backpressure.
- Support startup cancellation and process-group cleanup, retaining exit status and the last 16 KiB of stderr while omitting raw diagnostics from `Debug` output.
- Extend the Bazel crate macro to support test-only binaries and fixture entry points outside `src/`.
## Testing
Add process integration tests for framed communication, startup cancellation, helper and descendant cleanup, repeated close calls, and bounded diagnostics from startup and runtime failures.
GitOrigin-RevId: ed539e7899af06ee83a0d8c2d0ea8cec10f19afb
## What changed
Keep inherited incremental tool declarations in MCP-disabled prediction forks and `thread/sample` requests, and append a developer notice that MCP tools are unavailable. Skip tool declaration updates within the inherited context window; new windows still declare the current tools.
Add the default-enabled `prediction_preserve_parent_tools` feature flag and its configuration schema entries.
## Testing
Update core snapshots and app-server tests to cover inherited declarations, the MCP-unavailable notice, preservation across MCP refresh, and continued parent tool availability.
GitOrigin-RevId: 3adf96c7d0e0093986dbdbd540bd47674a2c105c
## What changed
Accept `[network_proxy]` in `requirements.toml`, retaining `[experimental_network]` as a compatibility alias. Reject both names in a single layer and normalize them before merging across layers so precedence and source tracking are preserved.
Honor the new spelling during credential broker project discovery, display `network_proxy` in debug configuration, and update diagnostics and documentation. Document the distinction between managed requirements, proxy feature configuration, and permission profiles. Policy publishers must keep using `[experimental_network]` until all clients and policy validation layers support the new spelling.
## Testing
Add coverage for alias equivalence, duplicate rejection, cross-layer precedence and sources, and broker project discovery. Exercise both spellings in proxy configuration, network approval routing, app-server requirements responses, and Windows machine policy validation.
GitOrigin-RevId: 5c5bb82bd4b6b1431aa97f27248775820eae6302
## Why
Mouse capture prevents the terminal from handling link-opening gestures in expanded questions.
## What changed
Disable mouse capture while questions are expanded and the TUI owns the screen, unless an interactive modal is active. Restore the default capture policy when questions collapse.
## Testing
Add a regression test covering expansion, collapse, non-owned screens, and link visibility with warnings open.
GitOrigin-RevId: 1fd37feb5c9cd374b492218eeef8c80316bb1cf9
## What changed
Replace screen-specific `OverlayInput` variants with `MouseCapture::{Inherit, Enabled, Disabled}` and rename the setter to `set_mouse_capture`.
Preserve existing capture behavior: transcript and usage overlays enable capture, onboarding and static pagers disable it, and the inherited policy follows screen ownership. Update the alternate-screen and lifecycle tests to use the new policy.
GitOrigin-RevId: 965a3bb6d0854e289d2b0dbeedbf2b252b98293d
Compact token counts can round to `1000K`, `1000M`, or `1000B` near unit boundaries. Promote these values to the next suffix so, for example, `999,500` tokens displays as `1M` instead of `1000K`.
GitOrigin-RevId: 803e7c8c8eebd61522fb717275b43904a5da056f
## Why
Remote App Server sessions support the command center, but the empty-prompt Left shortcut and its footer hint were enabled only for local daemon sessions.
## What changed
Enable the shortcut and `← for agents` hint for remote sessions. Centralize command center availability in `AppServerTarget::supports_command_center()` and use it consistently across navigation, lifecycle handling, trust prompts, and command center actions. Embedded sessions keep command center support disabled.
## Testing
Extend navigation coverage to verify the footer hint and opening the agents overview for both local daemon and remote sessions, while keeping navigation disabled for embedded sessions. Add a remote-session footer snapshot and update related UI tests to use the shared capability flag.
GitOrigin-RevId: 8148812217f68cf0fd441c35ed3c5b466ecc9cbd
## Why
MCP completion events can truncate large results and omit content removed for model consumption. Rollout traces need the original response, including content and metadata, as well as results for calls denied before reaching the backend.
## What changed
- Record MCP runtime results before callbacks, content filtering, and UI truncation, and record skipped calls as failures.
- Stop deriving MCP runtime completion records from protocol events to avoid duplicate records.
- Treat MCP runtime payloads as opaque results when reducing agent interactions.
- Buffer JSON trace writes and explicitly flush them.
## Testing
Extend app-server tests to verify that traces retain oversized MCP text, audio, structured content, and metadata while UI results remain truncated, and that denied calls produce exactly one failed runtime result with the denial reason.
GitOrigin-RevId: 57880770545eb5869420d7dc6fa4a15e481cae9d
## What changed
When `features.untrusted_as_tool_output` is enabled, emit untrusted additional context as `function_call_output` items in the `agent` namespace before user input. Use the explicit context name when supplied; otherwise derive a bounded name from the source key, falling back to `untrusted_content`.
Deduplicate these outputs by name and truncated value so name changes are emitted while changes confined to truncated content are ignored. Application context remains in developer messages, and disabling the feature preserves the existing message format.
## Testing
Extend core and app-server tests and add request-history snapshots covering both formats, turn start and steering, derived names, truncation, and deduplication.
GitOrigin-RevId: cd5e2f4b3121714acb7f4baf5607f3c27d408cae
## What changed
- Separate native child spawn preparation from submission and move forked-history loading and filtering into `agent::history`.
- Group resolved session startup dependencies in `ThreadStartupContext` and extract helpers for effective spawn configuration and inherited environment requests.
- Share loaded-recipient message submission and capture only the content needed for communication logging, avoiding a clone of the full message.
GitOrigin-RevId: 4417ba6ca35e9f293064600f0a54932de514636f
## What changed
Remove the `i18n-config` Git patch and its `cargo-deny` Git source allowance. Update the Cargo and Bazel lockfiles to use the crates.io release of `i18n-config` `0.4.8`, restoring its `basic-toml` dependency and adjusting the locked TOML dependencies.
GitOrigin-RevId: 4d4f6c52dddf79d2006e170432347ab79280da51
## What changed
Add `WorldStateSectionContribution::with_window_prefix()` to render extension developer fragments as separate messages before retained history when building a context window, including after compaction. Updates within an existing window still append to history. Ignore fragments with other roles for sections that opt in.
## Testing
Add a unit test for prefix placement and duplicate avoidance, plus local and remote compaction scenarios covering live updates, persisted replacement history, and rejection of non-developer fragments.
GitOrigin-RevId: 8621457c6eec17f1585ca8e6fa154b1bf3257330
## Why
Image generation usage-limit errors with the `imagegen_premium` limit ID were not recognized as structured `UsageLimitExceeded` failures.
## What changed
Recognize `imagegen_premium` alongside `image_gen`, preserving the limit ID and available reset time in image generation failure metadata.
## Testing
Extend app-server coverage to verify premium limit metadata and reset-time fallback in completion events, thread reads, and resumed threads. Add unit coverage for missing exhausted-window reset times and unrelated or absent limit IDs.
GitOrigin-RevId: 8cf991776403ddce1f45d9780b8040982fd0fcfe
## What changed
Collect REPL evidence as shared immutable response records, then select and render it during synchronous context preparation. Share response selection logic between text and multimodal layouts while preserving rendering limits, omission markers, and image order.
Use the shared `NodeReplResponse` type in core evidence storage and preserve existing snapshots through copy-on-write image eviction.
## Testing
Extend tests to verify shared response identity during collection, unchanged rendering after preparation, and snapshot stability when storage pressure evicts images.
GitOrigin-RevId: 8564d3732faa5adf01a66bca523d4c03cfbe1822
## What changed
- Validate inherited options before and after the `queue` subcommand, with explicit errors for unsupported flags and positional prompts.
- Reject `--model` and `-c model=...` because queued messages use the thread's model.
- Allow `--cd` for local server startup, but reject it with `--remote`.
- Hide unsupported inherited options from queue help and clarify the scope of startup configuration overrides.
## Testing
Add regression coverage for unsupported options in both argument scopes, model configuration overrides, remote `--cd` conflicts, and queue help output. Preserve coverage for overrides that bypass a running local daemon.
GitOrigin-RevId: 703ba26f38930a01559847e66e1af3d0d338d1e9
## What changed
Add session options for client- or server-owned output truncation and optional `max_output_tokens` budgets for wait and terminate observations. Introduce `TerminateRequest` and update session implementations and callers to use it.
Extend the stdio and gRPC schemas with optional truncation settings and budgets, and define the `bounded-output-v1` capability. Existing sessions retain client-side truncation; providers reject server mode by default. This change defines the contracts without enabling server-side truncation.
## Testing
Extend protocol serialization coverage for `outputTruncation: "server"` while preserving existing wire shapes when optional fields are absent.
GitOrigin-RevId: 22145897ea16d385c5ba9e7549109f7a669fceb4
## What changed
- Allow selecting warning text while preserving wrapped URLs and hard line breaks when copying.
- Add mouse-wheel scrolling within the warning body and keep page navigation working after selection.
- Use the shared menu surface and show configured scroll hints only for directions with more content.
- Preserve painted backgrounds when rendering text selections.
## Testing
Add coverage for warning selection without changing the draft, paging after selection, wheel scrolling and directional hints, and selection boundaries in scrolled text containing tabs and wrapped words. Update warning panel snapshots.
GitOrigin-RevId: c4b77277a60b7b4af92043cb3761769ddc636454
## Why
Sandbox invocations without an explicit permissions profile and remote `exec-server` connections using ChatGPT auth need access to cloud-defined model providers and managed requirements. Cloud bootstrap requests must also respect local application network policy.
## What changed
- Bootstrap sandbox cloud config whenever managed config is included, even without an explicit profile. Skip bootstrap when `--sandbox-state-json` supplies the sandbox state.
- Load cloud config for remote executors beyond workload identity, while skipping forwarders and executors using stdin credentials, AWS SigV4, or agent identity auth. Honor `CODEX_API_KEY` selection so API key connections skip ChatGPT cloud config.
- Apply local application network policy during cloud bootstrap and activate effective application network policy before exec-server clients are created.
## Testing
Add coverage for cloud-defined providers in sandbox and remote exec-server invocations, API key bypass, local policy blocking bundle requests, cloud policy blocking remote registration, and bootstrap exclusions.
GitOrigin-RevId: e8bd6210751e96161f575ade309ebf41bf10f8b5
## Why
The Bazel V8 source build supported Windows GNU but lacked an MSVC-targeting toolchain to produce `*-pc-windows-msvc` archives.
## What changed
- Add opt-in archive targets for native Windows x64 and ARM64 hosts, selected by `//third_party/v8:rusty_v8_native_windows_archive_for_target`.
- Fetch pinned LLVM and scope its `clang-cl` toolchain to V8 artifacts, using the installed Microsoft SDK. Bundle Chromium libc++ and compiler-rt builtins into the resulting `.lib`.
- Adapt V8 dependencies, assembly, snapshot generation, and platform feature settings for MSVC, and derive test metadata from the selected engine features.
- Document the native build workflow. Existing MSVC consumers continue using prebuilt artifacts; generated Rust bindings and publishing integration remain separate.
GitOrigin-RevId: abd5049245aece90a116fc3bfeac2b158a76f6af
## What changed
Emit `codex.tui.embedded_start` when the TUI successfully connects to an embedded app server, with a `reason` tag identifying daemon exclusions, disabled auto-start, failed daemon connections, or agent startup without a discovered daemon.
Distinguish `--search` from other configuration overrides when it is the only configuration exclusion preventing daemon use.
GitOrigin-RevId: b837ad2e83af17ea92392ffa6d5f91108ceaeecc
## Why
Cloud conversations own their execution settings and workspace. TUI requests must preserve those settings instead of overriding them with local configuration.
## What changed
- Add a distinct cloud parameter mode that omits local execution settings from thread start, resume, and turn requests, including misalignment continuations.
- Route cloud model and reasoning selections through `thread/settings/update`, requiring server acceptance rather than falling back to local changes or saved defaults.
- Use server model defaults and tolerate an unavailable `configRequirements/read` method during cloud bootstrap.
- Skip local tool setup and TUI-generated titles, and report that permission selection, forking, and conversation recaps are unavailable for cloud conversations.
## Testing
Add regression coverage for cloud request parameters, bootstrap without configuration requirements, rejected model changes, and suppression of unsupported requests.
GitOrigin-RevId: a2dafb6c8a6b0db8607575e2291fee739c2fb2b1
## What changed
- Make the `fast-mode` status line and terminal title items show the current model's processing tier name, falling back to `Standard`, instead of `Fast on` or `Fast off`.
- Share tier label resolution with `model-with-reasoning`, including `Flex` for configured providers other than Amazon Bedrock, and remove the ChatGPT account requirement for displaying tier names.
- Refresh model-dependent surfaces when Fast or Ultrafast mode is enabled or disabled.
## Testing
Update status surface tests and snapshots to cover tier selection, feature toggles, model changes, and provider-specific `Flex` fallback behavior.
GitOrigin-RevId: 7d67ae6177bb1b3c0be4ecf0910106aaaf2bd0be
## What changed
- Add optional `omitted_paths` and `denied_reads` fields to catalog permission messages. The latter requires exactly one `{{ denied_reads }}` placeholder.
- Preserve mandatory denial and no-bypass warnings, path/glob facts, and existing path selection limits. Limit each override to 500 UTF-8 bytes and fall back independently to bundled wording for invalid overrides.
- Pin `i18n-config` to an upstream revision that removes the unmaintained `basic-toml` dependency, updating Cargo and Bazel lockfiles.
## Testing
Add serialization and rendering coverage for sparse values, invalid templates, byte limits, and preserved policy facts. Extend model-switch scenarios to verify that warning wording follows the selected model while preserving request history and permission annotations.
GitOrigin-RevId: f5fa1a978abe07d90917f552c64e7c8fc257c061
## What changed
- Add the disabled-by-default `skill_catalog_deltas` feature flag to append new and updated skills without repeating unchanged catalog entries.
- Share a cumulative metadata budget across executor, cloud, and host catalogs, preserving usage across turns and resume. Removals emit no update and do not refund budget.
- Rebuild the current catalog and reset its budget after compaction, including any required skill root mappings in updates.
## Testing
Add unit and integration coverage for update costs, shared source budgets, feature rollback, and catalog updates across resume and compaction, with a request-history snapshot.
GitOrigin-RevId: e88b4265d7361498113d43fdc2e0260a9f930bbc
## What changed
Extract patch parsing, verification, and permission assessment into request preparation helpers used by the tool handler and intercepted shell patches. Execute the prepared `ApplyPatchRequest` through the existing runtime and derive auto-approval status from its approval requirement.
Move approval action construction onto `ApplyPatchRequest` and update the existing approval tests to use the new helpers.
GitOrigin-RevId: 7f07d38f0dbf2a971c94b897281651b7a174fd05
## What changed
Introduce `PreparedPermissionRequest` to encapsulate argument parsing, path resolution, permission normalization, and approval action construction. Pass the prepared request, including the selected environment ID, into session permission handling.
## Testing
Extend the selected-environment path resolution test to assert that the prepared approval action carries the expected environment, reason, and resolved permissions, matching the emitted permission request.
GitOrigin-RevId: ebd34fad0e5d4c9f98330d17a6254325526b8c78
## Why
Async question titles support Markdown, but named choices display Markdown syntax as plain text.
## What changed
Render named choices with Markdown styling and terminal hyperlinks, wrapping them to the available width after the numbered prefix. Use the rendered rows for height measurement and scrolling, and reuse layout measurements for the option tip.
Share viewport-aware Markdown rendering between question titles and choices, preserving hyperlink destinations when splitting overwide tokens.
## Testing
Extend tests to cover Markdown-aware height measurement, italic styling, and terminal hyperlinks in selected choices. Update the long-choice snapshot to show text starting beside its numbered prefix.
GitOrigin-RevId: 7a1292ac7dff16b55439888d569fc7fa7c6ef689
## Why
Cache presence and freshness checks deserialize full plugin records even when callers only need to decide whether a cached catalog is available.
## What changed
- Probe cache availability without deserializing plugin records, while still requiring a valid catalog envelope and a `plugins` array.
- Let `PreferFreshCache` reject stale catalogs from a 256-byte prefix when the header provides enough information; fall back to a full read otherwise.
- Limit discovery cache probes to the user and workspace scopes that need them, skipping the global cache probe.
- Serialize cached plugin slices directly without cloning them.
## Testing
Add coverage for malformed cache headers and payloads, reordered fields, stale-prefix rejection, and deferring plugin-record validation until a full catalog load.
GitOrigin-RevId: 1e5ec95917f38c84bba30dbd3bb8c2f91cc7e3a8
## Why
Tool suggestions loaded and cloned the cached connector directory even when no candidates remained after excluding accessible apps.
## What changed
- Filter out accessible connectors before loading the directory, skipping the lookup when no candidates remain.
- Share cached directory entries through `Arc<[AppInfo]>` and clone only matching entries for suggestions.
- Preserve placeholder suggestions for candidate connectors missing from the directory.
## Testing
Add coverage for skipping directory lookups with no remaining candidates, sharing cached storage, and preserving directory metadata and missing-connector fallbacks while excluding accessible apps, including disabled ones.
