## What changed
- Require the parent thread to be live before forking its history.
- Read the history mode and multi-agent usage hints from that live parent so
the fork loads and filters history using the active configuration.
- Verify that forking a legacy parent keeps the child in legacy history mode.
GitOrigin-RevId: 79416b78544467a1801f21300d3fe8db4fef59df
## What changed
- Track adjacent cells with the same OSC 8 destination and emit a single
hyperlink around their visible text.
- Close active hyperlinks before non-link content and at the end of a draw.
- Cover a production-length browser authentication URL at narrow terminal
width, including the remote-login guidance and cancellation footer.
GitOrigin-RevId: 9b87166ce78578137dfd2bf19db359ac83a908ee
## Why
Streamed message deltas can be dropped when the transport is saturated, leaving
clients with a truncated final response.
## What changed
- Include the last non-empty final agent message in successful `turn/completed`
notifications and mark the items as a summary.
- Treat completed message content as authoritative in the TUI, repairing an
incomplete stream while avoiding duplicate messages when `item/completed` was
already received.
- Continue backfilling full turn items for persisted `codex exec` threads when a
completion contains only the summary view.
## Testing
Added coverage for completion summaries, dropped stream deltas, duplicate item
handling, and directive-only responses.
GitOrigin-RevId: ffe9d36d683d6b6690e4a468ff68aa9189fe6ab7
## Why
Session header rows can exceed the available inner width when the terminal is
narrow, causing the bordered header to render wider than its requested width.
## What changed
Truncate each session header row to the available inner width and append an
ellipsis when content overflows.
## Testing
Add a snapshot test for a 44-column session header and assert that every
rendered line matches the requested width.
GitOrigin-RevId: 7cf0ea48aa95a6f1ddd1a9dbb7c7fb70bdbcb5a3
## What changed
Apply the existing whitespace-only line normalization to both streaming and
finalized agent Markdown. Blank lines now discard indentation and stale
hyperlinks while preserving their line style.
GitOrigin-RevId: f6150190b02f8cd8c853220cae1a2dcd2f4578a5
## What changed
- Size the unified mention popup from its filtered row count, while keeping a one-row minimum and the existing maximum.
- Update composer snapshots to cover the compact layout when only one mention result is visible.
GitOrigin-RevId: 7cd30a5c53c7e81cf7158a6b3dda3c09bd024f29
## What changed
- Let `exec-server` issue JSON-RPC requests to its client and correlate responses, with bounded concurrency, timeouts, and connection cleanup.
- When `request_policy_decisions` is enabled, forward proxy policy requests with the process ID and network destination, then apply the client's allow, deny, or ask decision.
- Fail closed for invalid inputs, unavailable or malformed responses, timeouts, process shutdown, and disconnects. Keep callbacks active while inherited process streams keep the proxy alive.
## Testing
- Cover response correlation, request limits, timeouts, disconnect cleanup, validation boundaries, decision forwarding, and process lifecycle behavior.
GitOrigin-RevId: 60e658102c50036589ca9de844760a8bffaa53b0
## What changed
- Add a `codex-git-attribution` context contributor that resolves the workspace's `commit_attribution_enabled` setting and supplies matching commit and pull request instructions through World State.
- Cache resolved policy by authentication generation, recover from unauthorized responses, and fail disabled on timeouts or settings errors with deferred retries.
- Handle enabled, disabled, and legacy attribution fragments so policy changes replace stale instructions without duplicating attribution.
## Testing
- Cover World State transitions, policy resolution after unauthorized responses, and authentication changes during an in-flight settings request.
GitOrigin-RevId: 6f733e708b5c960ba5e90751110910a03d1ba2df
## What changed
- Use `ClientRequest::method_name()` directly when preparing typed request
diagnostics for in-process and remote clients.
- Allocate the owned method name only when constructing an error.
- Remove the serialization-based method lookup and the redundant allocating
`ClientRequest::method()` helper.
GitOrigin-RevId: 93859e512a4f20204e0db4f929a2baebe4374ec5
## What changed
Treat `previous_response_not_found` websocket errors as retryable so Codex can
retry with the full request. Preserve the server-provided error message when
available, with a fallback message that explains the retry.
GitOrigin-RevId: 7fb6a1b4f396de561c491a16d793e2730b052f01
## What changed
- Decode `JSONRPCRequest` into `ClientRequest` without serializing the entire request back into an intermediate JSON value.
- Define every client method's wire name explicitly and use it directly for request, response, and tracing method lookups.
- Serialize outgoing transport messages directly to JSON strings instead of first building a `serde_json::Value`.
## Testing
- Add regression coverage that compares direct request conversion with Serde decoding, including omitted and null parameters, legacy methods, and unknown methods.
- Verify that direct outgoing-message serialization preserves the notification wire shape.
GitOrigin-RevId: 304e14bcaea24e32743bf852a60a208e2f273db3
## What changed
- Add the disabled-by-default, under-development `mcp_2026_07_28` feature.
- Include the feature in the configuration schema and app-server experimental
feature enablement API.
GitOrigin-RevId: 869835ee72f063d79ca2ecd9f2655d2efc457292
## Why
Core-compatible catalog rendering needs to preserve the core renderer's skill
priority, including when metadata budgets omit lower-priority entries.
## What changed
- Carry each host skill's `SkillScope` into its catalog entry.
- Under `CoreCompatible`, order visible skills by system, admin, repo, and user
scope, then by name and prompt resource ID.
- Preserve insertion order under `ExtensionCompatible`.
## Testing
Add coverage for propagating host skill scope and for both rendering policies.
GitOrigin-RevId: 9594a177edb2166abf1b5719c51a46fcee000600
## What changed
- Initialize the thread lifecycle input without an MCP resource client.
- Call `contribute_thread_context` without the removed step-scoped data argument.
GitOrigin-RevId: 689a982ba49c2788dde6bc2cbe0d6d7cae6c0a73
## What changed
When even the minimum skill catalog exceeds its metadata budget, render each
included entry without its description. This allows more skill names and
locators to fit before the remaining entries are omitted.
## Testing
Add coverage for extreme budget pressure and verify both the extension and
production-turn catalogs omit descriptions while staying within budget.
GitOrigin-RevId: 72cec10e9587beabbd3d8c6d53b931deb76824e6
## What changed
- Remove the step-scoped `ExtensionData` argument from context, turn-input, and tool contributors.
- Pass the host's optional `McpResourceClient` through `ThreadStartInput` so extensions can retain session capabilities explicitly.
- Keep the MCP resource client in skills-owned session state for catalog loading and skill tools.
GitOrigin-RevId: bafa77bcd998aff408d6a396c5fd9ac268c4cce4
## What changed
- Make `McpResourceClient` resolve resource operations and cache identity from
the latest `McpRuntime` connection snapshot.
- Remove step-bound resource clients from `McpBinding` and the associated
per-binding client identity tracking.
GitOrigin-RevId: ee59f5867308c5a63e6e232384a50cf1e0c2a011
## Why
Long skill descriptions can consume the catalog's metadata budget before later
skills are listed, hiding otherwise usable skills from the model.
## What changed
- Reserve space for every skill's name and locator when those minimum lines fit.
- Distribute the remaining token or character budget across descriptions in
round-robin order.
- Fall back to omitting entries only when the minimum catalog cannot fit.
## Testing
Added extension and production-turn coverage that verifies moderate budget
pressure keeps every catalog entry, shortens descriptions evenly, and avoids an
omission marker.
GitOrigin-RevId: 41971e4b47a86863b3839707b5cffcd8d83b888c
## What changed
- Publish `install.sh` and `install.ps1` from stable release assets to the
mutable `codex/install.sh` and `codex/install.ps1` R2 keys.
- Require both installer assets and verify each uploaded object's size,
SHA-256 metadata, and CRC64 checksum before completing publication.
- Leave prerelease publication unchanged.
GitOrigin-RevId: 869f5fcd6c5f5d7fa4dc39c5216b31409d595fc9
## Why
Startup prewarms and Guardian review sessions do not need workspace Git metadata. Collecting it for those requests performs redundant work, while user turns still need a fresh view of the repository.
## What changed
- Add a per-session Git enrichment policy.
- Skip enrichment for startup prewarm, preview, and Guardian review turns.
- Keep fresh enrichment enabled for regular sessions and one-shot delegated turns.
## Testing
- Cover prewarm and Guardian requests omitting workspace metadata while subsequent user turns observe repository changes.
- Cover concurrent repositories and worktrees retaining distinct metadata.
- Verify concurrent enrichment is coalesced and canceled enrichment can be retried.
GitOrigin-RevId: 4a68615288bb568c75f2e487d9c0776e3e80f191
## What changed
- Treat output-task closure as the signal that trailing output is complete, drain any remaining chunks before publishing command completion, and retain the grace period as a fallback.
- Wait for deferred network-denial classification before emitting the final command result.
- Serialize `write_stdin` interaction and completion events so an interaction that exits a process is published first, and avoid pruning processes while their terminal events are being finalized.
## Testing
- Add coverage for late output, missing output-close signals, late network denials, interaction/completion ordering, cross-platform aggregated output, and pruning during finalization.
GitOrigin-RevId: 46a118552bb1a4658b78aa5a5ca76eb8c5fba571
## What changed
- Use `McpConnectionSet` as the primary name for the collection of active MCP
server connections throughout `codex-mcp` and its callers.
- Keep `McpConnectionManager` as a backward-compatible type alias.
GitOrigin-RevId: 9753838b4fd0a0b6429a9c4af0c077137616f388
## What changed
- Add the action-risk review prompt template and default generic security policy to the `codex-auto-review` catalog entry.
- Define its `never` approval and `danger_full_access`, `workspace_write`, and `read_only` permission messages.
GitOrigin-RevId: 025bb609c12ae9d5235054747267a1ee46d118ef
## What changed
- Include the Codex `session-id` and `thread-id` headers when starting realtime conversations over WebSocket or WebRTC.
- Add coverage confirming that WebRTC call creation forwards both identifiers while preserving the existing realtime request metadata and SDP payload.
GitOrigin-RevId: 668bee9a7d4797ad0a396e9ca4dc56b2c379cba7
## What changed
- Use the configured route-aware HTTP client pool for LM Studio server requests.
- Add connection-timeout support to `HttpClientBuilder` and route-aware pools, and keep LM Studio's five-second limit scoped to connection establishment.
- Verify that LM Studio accepts a response that arrives after the connection timeout has elapsed once the connection is established.
GitOrigin-RevId: c4300f4b5d37c4418822783ab09cb50d506ee423
## What changed
- Document `codex-http-client` as the owner of direct `reqwest` integration and shared outbound request policies.
- Explain how to select outbound proxy policies, retain clients for connection reuse, and use route-aware pooling for multi-URL and redirecting traffic.
- Add examples for constructing policy-aware clients and transports, plus guidance for direct routing and sensitive request data.
GitOrigin-RevId: 892db4be92af5ec42eced8d7dec4651c9f464689
## Why
Forking a persisted thread could lose its approvals reviewer and fall back to
configuration defaults.
## What changed
- Restore the latest persisted approvals reviewer from the full source history
when creating a fork, while continuing to honor explicit overrides.
- Keep boundary-based history truncation independent from reviewer restoration,
so a fork at an earlier turn retains the source thread's latest setting.
## Testing
- Add an app-server test that sets auto-review, forks at an earlier turn, and
verifies the fork reports auto-review.
GitOrigin-RevId: 41c515755de7de600f71c1259f96908f2d169ca7
## Why
ChatGPT token refresh requests need to follow the same configured routing policy as other authentication traffic, including environments that use the system proxy.
## What changed
- Require an `AuthRouteConfig` throughout login, logout, token refresh, personal access token, and agent identity flows.
- Build auth HTTP clients directly from that configuration instead of falling back to a default HTTP client when routing configuration is absent.
## Testing
- Add an integration test that refreshes a token through a cached system-proxy route and verifies the proxy receives the expected request.
GitOrigin-RevId: 7d54ab3219939a49921c51faf08cd4c2eabca51c
## Why
Turn diffs need to render paths from remote environments whose path convention may differ from the Codex host.
## What changed
- Preserve `PathUri` values through applied patch deltas, display-root discovery, and turn-diff tracking.
- Add host-independent relative-path rendering and normalize Windows drive-letter case in `PathUri`.
- Render paths relative to each environment's repository root while keeping Git diff headers slash-separated.
## Testing
- Cover POSIX, Windows, UNC, encoded-separator, and opaque URI relative paths.
- Verify an applied patch in a remote Windows working directory emits a portable unified diff.
GitOrigin-RevId: 526f70ae36a40627de5496d375310d12295b69bb
## What changed
- Send the streaming SSE request-body drain test through `HttpClientFactory`.
- Replace the test-support crate's direct `reqwest` dependency with
`codex-http-client`.
- Remove `core_test_support` from the temporary direct-`reqwest` exceptions.
GitOrigin-RevId: 16ea4309d0b575592c2e59991eb6dce18d9467ed
## Why
Auth managers should use the application's resolved HTTP client factory instead
of silently falling back to the transport's default proxy behavior.
## What changed
- Make `AuthRouteConfig` required when constructing an `AuthManager` or
`AuthConfig`.
- Pass each production caller's resolved routing configuration through without
wrapping it in an optional value.
- Add a test helper that explicitly selects the transport-default proxy policy
for callers that do not exercise custom routing.
GitOrigin-RevId: d89a3b1f8b5d4007650cdac0aae241c94d598580
## Why
Auth routing represented the default proxy policy as an absent configuration,
leaving consumers to reconstruct the fallback HTTP client independently. Carry
the application's resolved policy explicitly so auth and related requests use
the same client configuration.
## What changed
- Build `AuthRouteConfig` from the resolved `HttpClientFactory` for both
`ReqwestDefault` and `RespectSystemProxy` policies.
- Pass that route configuration through login, auth, cloud task, and cloud
configuration flows, and reuse its factory when loading cloud configuration.
- Log cloud-task configuration load failures before falling back to the
transport-default proxy policy.
## Testing
Extended configuration tests to verify that effective and bootstrap auth routes
select the expected proxy policy when system-proxy support is enabled or
disabled by feature requirements.
GitOrigin-RevId: d03802e2660f5cf6d940e8e718ec5c82ede7eab1
## What changed
- Assign IDs to client-created response items in every session, including streamed items, forked history, compaction results, and non-OpenAI provider requests.
- Preserve server-provided IDs and stable generated IDs across persisted and resumed conversations while continuing to omit unprefixed server IDs from outbound requests.
- Retire `features.item_ids` as a configurable feature. Existing configuration and CLI toggles remain accepted as compatibility no-ops.
## Testing
- Cover default ID assignment, persistence and resume behavior, remote compaction, provider requests, WebSocket requests, and removed-feature compatibility.
GitOrigin-RevId: 7a09e2d07d2606c2ef1e8e2283d36cb555557eae
## Why
Git can interpret a requested commit SHA as a branch name when the remote's
default branch has the same name. This can cause a marketplace plugin source
to materialize a different commit than the one it pinned.
## What changed
Resolve `HEAD` after checking out a SHA-pinned Git plugin source and reject the
source when the resolved commit does not exactly match the requested SHA.
Ref-name checkouts retain their existing behavior.
## Testing
Add a regression test with a default branch named after another commit's SHA
and verify that materialization rejects the mismatched checkout.
GitOrigin-RevId: c19cbd98ee6167dad7b2ee72e283b3bd30b59713
## Why
`codex-http-client` is the intended owner of direct `reqwest` usage.
## What changed
- Build Codex's default and route-aware clients with `HttpClientBuilder`, and return `HttpClient` directly to API, model discovery, auth, remote control, skills, and extension callers.
- Preserve custom CA, proxy, Cloudflare cookie, sandbox, and request-logging policies while removing `codex-login`'s direct `reqwest` dependency.
- Use shared HTTP types for auth headers, status codes, transport errors, and login-server tests.
## Testing
- Add a Linux integration test verifying that a regular Responses API turn traverses the configured system proxy.
GitOrigin-RevId: 714695fb80762d2083e2f7a6414183e2b3b63854
## What changed
- Make the generated Linux proxy socket directory readable inside restricted
`bubblewrap` sandboxes so the proxy bridge can connect.
- Route `WS_PROXY` and `WSS_PROXY` through the Linux managed proxy bridge.
- Remove inherited proxy attribution tokens from unscoped executions while
continuing to replace them with the current token for scoped executions.
## Testing
- Exercise `WSS_PROXY` routing with a minimal filesystem policy.
- Cover attribution-token removal and replacement during environment setup.
GitOrigin-RevId: 2f14ddb26baab0147a786bc354d93eb5aad059f3
## Why
The PTY and pipe spawn helpers now require callers to specify which file
descriptors should be inherited, following
https://github.com/openai/codex/pull/13644.
## What changed
Pass empty inherited-FD slices from the Windows process-tree tests, which do
not need to preserve any file descriptors.
GitOrigin-RevId: 5e578df34e195251490608a163f8aaee0a6e681c
## What changed
- Apply root and scoped project instructions using the established precedence for `AGENTS.override.md`, `AGENTS.md`, and configured fallback files.
- Treat findings as rule-supported only when repository guidance adds material, repository-specific context beyond generic correctness advice.
- Deduplicate findings without losing their supporting rules, and cite the applicable instruction file and smallest relevant line range in each rule-supported finding.
- Continue reporting ordinary findings independently of whether repository rules apply.
GitOrigin-RevId: 64b26555d92c0baa7e8e005130a7fb032b91d170
## What changed
- Handle app-server `turn/start` rejections for pending user turns as turn
errors instead of exiting the TUI.
- Finalize the pending turn, display the failure in the transcript, and resume
queued input handling.
- Add coverage that submits a turn to a missing thread and verifies that the
error is shown while the app continues running.
GitOrigin-RevId: 6d291ba62b9e50d49dd4e3d7c429e98c1f754680
## Why
`codex-http-client` is the intended owner of direct `reqwest` usage.
## What changed
- Route agent identity registration, task registration, and JWKS requests through `HttpClient`.
- Preserve retry classification using `HttpError` and `http::StatusCode`.
- Remove `codex-agent-identity` from the temporary direct-`reqwest` dependency exceptions.
GitOrigin-RevId: 7445c9f2521e6d8ef0969a1483c81f797bf91316
## What changed
- Add `HttpClientBuilder` for configuring default headers, redirects, the
Cloudflare cookie store, and request diagnostics without exposing the
underlying transport.
- Provide factory-backed construction for fixed destinations that respects
outbound proxy policy, alongside explicit direct and legacy
transport-default construction paths.
- Preserve the request-logging setting in `ReqwestTransport`, so disabling
diagnostics also suppresses transport-level URL and request-body traces.
- Add `HEAD`, `DELETE`, and query-parameter helpers to the shared client
wrappers.
## Testing
- Verify builder configuration survives policy-aware construction and custom
CA fallback.
- Verify disabled request logging omits request URLs and bodies from transport
traces.
GitOrigin-RevId: 529c33abefeb88f38ff9a0ead374d29fcc872e6a
## What changed
- Check writable-root permissions for the sandbox group and root capability SID from a single DACL snapshot, and refresh the ACL when either SID is missing the required access or has a stale explicit delete-child grant.
- Start the command runner without loading a user profile and poll more frequently while waiting for it to become ready.
- Make the Windows sandbox binaries available to Bazel tests.
## Testing
- Add coverage that verifies ACL refresh checks every requested SID.
- Add an elevated non-TTY command test that verifies environment forwarding, stdout, and exit-code propagation.
GitOrigin-RevId: 657ed9dc906039299f9ffa4772e0926c47066a73
## Why
A fixed character limit does not account for the different context-window sizes supported by models.
## What changed
- Budget extension-rendered skill metadata at 2% of the resolved model context window, capped at 4,000 tokens.
- Keep the existing 8,000-character fallback when model context metadata is unavailable.
- Include the omission marker in the budget and still emit it when no skill entry fits.
- Apply the same resolved budget to executor and host skill catalogs assembled for a turn.
## Testing
- Cover proportional and capped budgets, multibyte fallback accounting, and omission-marker behavior.
- Verify through the production turn path that larger model context windows include more catalog entries without exceeding the computed budget.
GitOrigin-RevId: 4667293f1594de4dd605b32b9fa4255d26772c0f
## Why
Crossterm's Windows event backend expects Win32 input records. When the console
inherits virtual terminal input mode, or another console client restores it,
navigation keys instead arrive as literal escape bytes.
## What changed
- Keep the Windows console in input-record mode while the event stream is
polled, and disable focus-change reporting on Windows.
- Preserve and restore the console's original virtual terminal input setting
when the TUI shuts down.
## Testing
- Add unit coverage for clearing and restoring the virtual terminal input bit.
GitOrigin-RevId: 792b99e354fce357d51810a6c3b437e972ad11ce
## Why
Terminating a Windows execution session must also stop child processes, while a
normal root-process exit must continue to allow background descendants to run.
## What changed
- Assign Windows pipe, ConPTY, and sandbox processes to job objects and terminate
the job when a session is cancelled, times out, or is explicitly stopped.
- Preserve descendants when the root process exits normally.
- Attach ConPTY and sandbox processes to their jobs atomically at creation; keep
root-process termination as a fallback where job setup is unavailable.
## Testing
Added Windows coverage for descendant termination and preservation across pipe,
ConPTY, capture, cancellation, and legacy sandbox execution paths.
GitOrigin-RevId: 8f831f2fc4caaa7b79ce842a3ed7192bd02dd3b4
## What changed
- Resolve the full rollout lineage when loading model context for paginated threads.
- Reverse-scan each lineage segment up to its recorded byte boundary, stopping at segment metadata and preserving the requested thread's canonical session metadata.
- Add a bounded reverse-scanner constructor for scanning a frozen JSONL prefix.
## Testing
- Cover frozen-prefix reverse scans and nested lineages whose root rollout has been archived.
GitOrigin-RevId: 8b97da43a263b7bd09cb7883450bb19eba5f195f
## What changed
- Define the `network/policyRequest` RPC payloads for associating a network request with a process and returning an `allow`, `deny`, or `ask` decision.
- Cover HTTP, HTTPS CONNECT, and SOCKS5 TCP/UDP requests, with shared size limits for callback fields.
- Add the backward-compatible `requestPolicyDecisions` remote proxy option so executors can opt in to sending policy decisions to clients.
- Re-export the new protocol types from `codex-exec-server`.
## Testing
- Verify the request and decision JSON shapes.
- Verify that the proxy opt-in is omitted and defaults to `false` for legacy configurations, while an enabled value round-trips.
GitOrigin-RevId: 65b0a0723d1abb6e4f504a41d3a0dd41f5f21bf7
## What changed
Set `missing_path_behavior` to `None` for the minimal and project-root
filesystem entries in the custom-`arg0` exec-server test.
