## Why
On case-insensitive macOS filesystems, paths such as `.GIT/config` refer to protected `.git/config` metadata but can pass case-sensitive write permission checks.
## What changed
Check native filesystem case sensitivity when matching protected metadata paths, including case aliases in workspace roots. Recheck both the target and policy entries with normalized aliases so explicit metadata grants and narrower restrictions retain their precedence. Return errors when filesystem case sensitivity cannot be established.
## Testing
Add macOS coverage for metadata and workspace-root case aliases, explicit grants, narrower restrictions, and missing directories. Strengthen the patch regression test to assert the approval rejection message for both direct `apply_patch` calls and shell interception.
GitOrigin-RevId: 8ae2eb97ce6ec71c51bead130515b9ce6c1cdfab
## What changed
Add an integration test that approves a sandboxed `exec_command` attempt, simulates a sandbox denial, and denies the subsequent unsandboxed retry. Verify that Guardian reviews the retry separately with `require_escalated`, that the denied retry never reaches the executor, and that the tool result includes the denial rationale.
Use a fake executor to exercise the sandbox denial consistently across hosts.
GitOrigin-RevId: cd644255f7a7b7561c9e52a5b6e40f0859b70547
## Why
A failed Guardian inference can retain its input in a reusable session. Tracking transcript progress only after successful reviews can admit the same evidence again on retry.
## What changed
Advance transcript progress when a failed turn has retained its input and the session remains reusable, without counting it as a completed review or changing the committed fork checkpoint. Leave progress unchanged when failure occurs before input admission.
## Testing
Extend regression coverage for encrypted agent messages across review retries, pending evidence after compaction failures, and fork checkpoints after transcript admission without a completed review.
GitOrigin-RevId: 36239ec9d47f484bcfe68d65e7c8d8ab8660db0d
## Why
Guardian approval covers the permissions of the reviewed action. A retry outside the sandbox needs a fresh review of its broader permissions.
## What changed
- Track the initial approval source so Guardian approval does not preapprove an escalated retry, while preserving existing user and hook approval behavior.
- For exec retries that can run without the sandbox, set the approval action to `RequireEscalated` and clear `additional_permissions` so review and caching reflect the retry's actual permissions.
GitOrigin-RevId: 06f8d53745a7bcfe9fdb5628ff9e85da6060547d
## Why
Trimming interleaved realtime transcripts by utterance order can discard the latest speech from an earlier utterance. Evicting after each delta can also drop one speaker before the other speaker's delta from the same frame arrives, losing recent instructions at handoff.
## What changed
Use raw frame recency to trim timed frameless bidirectional transcripts within the 8 KiB budget. Defer eviction until the frame advances or the transcript is consumed, and retain both speakers' suffixes when they share the newest frame. Preserve conversation order and fall back to FIFO eviction when timing is unavailable.
Track trimmed prefixes so final transcripts can extend retained speech without making delayed finals appear newer.
## Testing
Add regression coverage for frame recency, same-frame event ordering, UTF-8 truncation, delayed finals, and untimed fallback. Add an app-server handoff test verifying that both speakers' recent speech and the latest user instruction survive while live transcript notifications remain unchanged.
GitOrigin-RevId: b01b729d8bdd4acb26e0385442ce40819355deac
## What changed
- Verify that freeform `apply_patch` calls and shell-intercepted patches cannot modify `.git/config` through `.GIT/config` when approvals are disabled, while an ordinary workspace file remains writable.
- Add macOS Seatbelt coverage for uppercase protected metadata paths, including absent directories, existing directories with either casing, and case variants of the workspace root. Assert that metadata creation and modification are denied while sibling workspace writes succeed.
The tests skip filesystems that do not support the case-insensitive aliases they exercise.
GitOrigin-RevId: 5cf6b0c36eee348e1ba0db0bc2d3bff072458364
## What changed
Use the active syntax theme's markup foregrounds for headings, emphasis, strong text, list markers, links, and blockquotes. Preserve existing bold, italic, and underline modifiers, and retain previous styles when a scope provides no foreground.
## Testing
Update rendering snapshots and streaming blockquote assertions for themed colors. Exercise existing fallback expectations with an empty syntax theme.
GitOrigin-RevId: b00aa4af30f73f538ff5f888a0f9b4edbdc15893
## What changed
Render local viewed images and generated image artifacts as bounded thumbnails in the rich fullscreen transcript using Kitty or Sixel graphics. Viewed images appear when their activity is expanded or the detailed presentation is active; generated images appear alongside their saved-path entry.
Keep previews clipped to the viewport, retain graphics across unrelated redraws, and remove them when overlays open. Bound image decoding and cache memory, and preserve text-only entries for remote workspaces, unsupported terminals, missing files, and oversized images. Image rows do not enter searchable or selectable text.
## Testing
Add layout and snapshot coverage for disclosure, viewport clipping, rewrapping, raw-mode fallback, deleted files, and oversized rasters. Add terminal coverage for retained Kitty graphics, repainting after a clear, local-file transport, and overlay cleanup.
GitOrigin-RevId: fb2ec146331acfcfc82b2b283616671c9ee93757
## What changed
- Remove feature-flag checks from managed worktree creation and repository-aware session discovery, while retaining local workspace and trust checks.
- Make TUI voice availability follow platform support instead of `features.realtime_conversation`.
- Ignore `features.worktrees` and `features.realtime_conversation` configuration overrides, warn when managed requirements reference them, and hide both flags from `/experimental`, including catalogs from older servers.
## Testing
Add coverage for ignored configuration overrides and managed requirements, and update session filtering, worktree grouping, and experimental feature discovery tests for the retired flags.
GitOrigin-RevId: 1d64e890e6e2f8a78926a9ea163126c0890b068e
## Why
MCP servers at `https://gov.chatgpt.com` were treated as untrusted for ChatGPT authentication and switched to OAuth, preventing local Gov Apps from retaining the ChatGPT auth provider.
## What changed
Trust the `https://gov.chatgpt.com` origin alongside the existing ChatGPT origin when resolving MCP server authentication. Origin matching preserves scheme, host, and port restrictions.
## Testing
Add regression coverage for Gov Apps URL construction, trusted origin normalization, rejection of lookalike hosts and nonstandard schemes or ports, and retention of the local ChatGPT auth provider. Verify that explicit OAuth servers and servers in remote environments do not receive the host provider.
GitOrigin-RevId: 7ceaf7c524d963005d9f23204489bbde269f0dd5
## Why
The app server retained its startup model provider for catalog requests, so signing in or out could leave `model/list` using stale provider settings or requiring a restart after managed provider requirements changed.
## What changed
- Invalidate the catalog after successful login and logout, then reload the effective configuration on the next model list or background refresh. Rebuild the models manager when the provider or catalog changes, while preserving existing threads' routes.
- Retain the original project context and the TUI's `--oss` provider selection across reloads. Retry configuration loading after falling back to defaults so temporary failures do not pin the fallback catalog.
- Keep provider policy checks for cached catalogs and apply runtime `api_key_model_discovery` toggles to the active catalog manager.
## Testing
Add and extend tests for provider selection and definition changes after login, catalog reloads after logout, OAuth gateway transitions, fallback recovery, project context, and runtime model discovery toggles.
GitOrigin-RevId: bce2e23ff567e1a52eac2b6ad736a6e63ff61e2b
## Why
The `/keymap` action catalog and root-config binding lookup duplicated the same action inventory, requiring both to be maintained together.
## What changed
Use `define_keymap_actions!` to generate `KEYMAP_ACTIONS` and `binding_slot` from a single declaration grouped by context. Preserve the existing action order, descriptions, feature gates, and binding mappings.
GitOrigin-RevId: 182e937d9642a8b5a4aa787691da793712f29010
## Why
Direct mode serves executor requests but applied the client's 8 KiB inbound request limit, causing larger `fs/writeFile` requests to disconnect the executor.
## What changed
Use a dedicated direct WebSocket connection constructor that omits the client inbound request limit while retaining WebSocket message and frame limits.
## Testing
Add a regression test that runs the direct environment and verifies successful file writes above the client request limit using both text and binary WebSocket messages.
GitOrigin-RevId: e8e77a5e8581ab9eb98446e23b77a6da41d64868
## What changed
Tag `codex.tools.incremental_updates` counters with the qualified tool name alongside the action. Continue excluding initial catalogs and namespace headers, while counting each removed namespace member.
Add `codex.tools.spec_description_bytes` to measure UTF-8 description bytes when an existing tool definition is replaced. Skip definitions without descriptions and use logarithmic histogram boundaries up to 1 MiB.
## Testing
Extend namespace transition tests to check per-tool counts and description sizes. Add scenario assertions for replacement metrics with incremental tool updates and their absence on the non-incremental request path.
GitOrigin-RevId: e20e6d81f21a867b285df1f0da005c2806dd03c6
## Why
With granular sandbox approvals disabled, `write_stdin` rejected input to terminals retaining additional permissions even when those permissions were still granted.
## What changed
Let input reach approval review when the terminal's retained permissions match active grants for its environment. Require identical filesystem grants, including entry order, and an active network grant when retained permissions enable network access. Each input still requires review.
Keep rejecting input when retained authority is no longer covered or the approval policy changes to `Never`.
## Testing
Add regression coverage for user and Guardian review, turn grant expiry, session grants, and switching to `Never`. Cover filesystem restrictions, protected metadata, symlinks, and ordered denials, and verify that rejected input never reaches the terminal.
GitOrigin-RevId: 9abf7da8d03b1526d26ca2a718e36349a255330b
## Why
Terminal status previously collapsed completed and failed turns into `idle` and reported blocking prompts without a reason. Blocking detection also depended on terminal title settings.
## What changed
- Emit `done` and `error` through OSC 7501 for live turn results, retaining them until deliberate keyboard, paste, or mouse input acknowledges them. Mouse movement does not acknowledge results.
- Classify blocking requests with `kind=permission`, `kind=question`, or `kind=auth`, including requests hidden behind another view or delayed while typing, independently of terminal title settings.
- Keep pending follow-up work and active goals `working`. Treat interrupted turns and replayed results as `idle` rather than new results.
- Preserve the existing iTerm2 OSC 21337 labels and indicators, mapping `done` and `error` to `Idle`.
## Testing
Add lifecycle and input-acknowledgment tests covering approvals, completion, failure, interruption, replay, pending follow-ups, and active goals. Extend blocking-request assertions and terminal protocol snapshots for the new states and reasons.
GitOrigin-RevId: 90bad1d54d8b3b9e3cec66fbd3bf3df0c42b995b
## What changed
Use the stable and experimental bundles generated by `//bazel/schema:app-server` as compile-time inputs for `app-server-protocol` instead of the checked-in bundles.
Generalize `schema_generator_sources` to `schema_sources` so it can stage Rust sources alongside generated bundles. Keep empty bundle placeholders for the on-demand schema generator, which derives its output from Rust sources.
GitOrigin-RevId: a976c420a3698d631f3ea7c698b15b82391158e5
## What changed
Wait for the subprocess readiness marker before cancelling in
`process_exec_tool_call_cancellation_allows_sigterm_cleanup`, removing the
one-second polling cutoff. Poll readiness alongside execution under the existing
five-second timeout, then cancel and await execution if that timeout expires so
cleanup completes before the test fails.
GitOrigin-RevId: ba47dad9ba87fb5dc3bd087380811655387f825a
## Why
Environment tool availability and selectors should remain stable as selected environments become ready.
## What changed
- Keep configured environment tools advertised even when no execution environment is ready, and derive `environment_id` selectors from all selected environments.
- Return guidance to wait when an environment is unavailable, while preserving errors for unknown environment IDs. Require a usable primary environment for `write_stdin`.
- Always include `shell` and `login` in the `exec_command` schema and mark `stable_environment_tools` as removed.
## Testing
Update integration tests to expect environment tools with empty or starting environments, and remove explicit feature opt-ins from affected scenarios.
GitOrigin-RevId: 1590c1b5be16a39e4a370663c552b881602545b5
## What changed
Emit the Daybreak notice after replacing or removing the placeholder session header so the notice follows the configured header.
## Testing
Extend the resumed-history snapshot test to start with a placeholder header and verify the full transcript order: session header, Daybreak notice, and replayed user and assistant messages.
GitOrigin-RevId: 536f717b2859d2fe319756f52123b4cd0407cb66
## What changed
- Add `//bazel/schema:app-server` to generate stable and experimental schemas from Rust sources without depending on committed precomputed bundles.
- Add `//sdk/python:generated` to generate Python SDK models, the notification registry, and API methods from the stable schema in scratch space, using dependencies from `uv.lock`.
- Add `generate-types --no-format` to skip formatters for build outputs while preserving formatting by default.
## Testing
Extend contract generation tests to regenerate in a temporary SDK copy, checking byte equality for formatted output and AST equality for unformatted output.
GitOrigin-RevId: 9ca7daa8ac0a33c4106a9e95c2f48bbded07df21
## Why
MCP request failures and tool errors reported only through `codex/telemetry` metadata previously received an `unknown` error code, obscuring the failure category.
## What changed
- Classify typed request failures into bounded codes such as `request_timeout`, `transport_closed`, and `protocol_error`, and carry them into MCP call metrics and spans before errors become strings.
- Preserve typed timeouts when a prepared tool call exhausts its deadline during trusted access lookup.
- Accept allowlisted `error_code` values from `codex/telemetry` as a fallback after structured content and connector authentication metadata. Keep model output unchanged and ignore unrecognized metadata codes.
## Testing
Add coverage for typed errors wrapped in context, prepared-call timeout classification, metadata precedence and rejection, unchanged model output, and exported span error attributes.
GitOrigin-RevId: d7a440a6c9119b8a07a7f1fad697eb25af506f00
## What changed
- Upgrade `rules_python` from 1.7.0 to 2.4.2 and update `MODULE.bazel.lock`.
- Enable `--windows_enable_symlinks` in `.bazelrc`, as `rules_python` 2.x requires symlink support for Windows Python launchers.
GitOrigin-RevId: 303da258c74b18d0d0df8d4eebb830c57f14cca4
## Why
Advancing the test clock expires the review, but command cancellation and output drainage still run asynchronously. The model can poll before the final timeout failure is available.
## What changed
Hold the initial tool result until the command emits `ExecCommandEnd`, with a bounded wait that also catches unexpected approval requests or turn completion. Only request a poll when the initial result reports a running process, and accept the timeout output from either `exec_command` or `write_stdin`.
Keep the assertions that the model receives the timeout explanation without a user approval prompt or a misleading user-rejection message.
GitOrigin-RevId: 219a1579dce35caf8f0d45b1d92a7343ec1a8935
## What changed
Add `ListKeymap::vertical_action_for` and `ScrollState::apply_vertical_action` to share key resolution, selection movement, and visibility handling across the experimental features, hooks, memories, skills, and multi-select views. Preserve navigation priority, search input handling, and item reordering precedence.
## Testing
Update scroll-state tests to exercise the shared action handler and picker tests to navigate through key events. Cover overlapping page-down and move-left bindings when item reordering is disabled.
GitOrigin-RevId: 29927b0a4de0fbeb4c0dd19c418b8f60fffb8a7d
## Why
Coordinated MCP OAuth refresh must stop retrying a definitively rejected refresh token, including after the runtime is rebuilt.
## What changed
Remove the rejected refresh token while preserving the access token and credential record. Compare stored credentials under the appropriate locks before writing so a replacement login is preserved, and update file entries using their existing keys.
Keep rejection handling alive through caller cancellation and prevent reuse within the runtime even if persistence fails. For ordinary direct-keyring credentials shared across `CODEX_HOME` directories, retire the token only in the current runtime because locking does not span those directories. Report persistence failures without exposing backend diagnostics.
## Testing
Add coverage for reauthentication after runtime rebuild, legacy file keys, cancellation with a concurrent credential replacement, keyring scope, and persistence failures with diagnostic redaction.
GitOrigin-RevId: a6e602ca2e2893ed711d853becc45142d9575fab
## Why
PowerShell safety checks can mistake a literal `start` argument for a URL-launch command, or combine a process launch with a URL from a separate command.
## What changed
Classify independently parsed literal PowerShell commands separately so commands such as `Write-Output start 'https://example.com'` do not trigger URL-launch checks. Retain conservative checks for pipelines, script state, executable strings, and shell or terminal wrappers, while continuing to detect actual URL launches and destructive commands.
## Testing
Add policy regression coverage for literal arguments, separate commands, URL launches, wrappers, and destructive commands, plus a Windows integration test covering execution and policy rejection.
GitOrigin-RevId: 2878aa86bc36b44c60230cc1de3430922b28b81a
## What changed
Rename the grant manager and supporting modules in `codex-rs/login` to expose `OAuthSessionManager`, its configuration and status types, `OAuthLoginControl`, and `subscribe_oauth_session_status`.
Keep the existing gateway API names as compatibility aliases and retain the credential storage paths and namespace so saved credentials remain usable. Update the existing authentication tests to use the OAuth session API.
GitOrigin-RevId: 72cea12be606dde28cf42809e7f8b8807cbc4a2a
## Why
Remote MCP environment filtering could drop `SystemDrive` and `LocalAppData`. Explicit overrides also need Windows-aware merging to replace inherited variables with differently cased names.
## What changed
- Preserve `SYSTEMDRIVE` and `LOCALAPPDATA` when remote environment variables activate the allowlist.
- Apply explicit environment overrides through the executor environment policy, while retaining the final overlay for variables excluded by the allowlist.
## Testing
Extend environment-policy tests to cover the additional Windows variables, overrides with differently cased names, and the final overlay used by older executors.
GitOrigin-RevId: 36df69117f248536e47cf7e1d855b99a138fe698
## Why
Unarchiving a thread previously read rollout metadata across both active and archived history, including unrelated threads.
## What changed
Use `RolloutReferenceIndex::scan_archived_threads` to restrict discovery to archived files whose canonical filenames match the requested thread. Continue validating ownership through session metadata and include compressed and reverted rollouts.
## Testing
Add coverage for compressed and replacement archived rollouts, metadata ownership mismatches, unrelated filenames, and exclusion of active rollouts.
GitOrigin-RevId: 8784f3502b839dcb4a3839744010e350d0196545
## Why
Thread stores need a way to reuse history and writer state loaded while preparing a resume, rather than loading them again during session startup.
## What changed
- Add an opaque, single-use `ThreadStoreResumePreparation` and an optional preparation in `StartThreadOptions`.
- Pass preparation through session startup to `ThreadStore::resume_thread_with_preparation`, which defaults to an unsupported-operation error.
- Reject preparation for ephemeral threads or threads without resumed history. Continue using `resume_thread` when no preparation is supplied.
## Testing
Add a regression test verifying that supplied preparation selects the prepared store path and propagates its unsupported-operation error instead of falling back to ordinary resume.
GitOrigin-RevId: 26537d9b83443bd56341d6afc713f32b999dc67c
## Why
Native extensions need configured Responses metadata for request attribution, but extension calls used the MCP metadata template, which omits it. Image requests also did not forward the turn metadata to the backend.
## What changed
Use the Responses metadata template for native extension calls while continuing to exclude tool inventory. Forward the resulting metadata in the `x-codex-turn-metadata` header on image generation and edit requests.
## Testing
Extend metadata tests to cover configured values in extension calls and app-server tests to verify `display_name` and `turn_trigger` on image generation and edit requests, including a Unicode display name.
GitOrigin-RevId: a2ffaa4d15259c662917612391b8717ee34b9c6c
## Why
Unsupported evidence currently shares a single Decisions comparison reason, making it difficult to distinguish why a comparison was skipped.
## What changed
Report separate reasons for unsupported developer messages, other non-user messages, trusted skills, images, and audio. Keep these outcomes classified as `skipped` and retain the generic reason for other unsupported evidence. Expose `TrustedSkills::KIND` for identifying trusted skill fragments.
## Testing
Expand adapter tests for the distinct rejection reasons and add a lifecycle case verifying that trusted skill evidence skips the Decisions request, reports `trusted_skills`, and preserves the baseline score.
GitOrigin-RevId: 98f076d1aa6771d0209e7f5910eed0dcc40c6263
## Why
Concurrent TLS client builds can independently load the same platform trust store. Share overlapping loads while preserving fresh trust reads for later builds.
## What changed
- Share one in-flight native root load without reusing completed loads.
- Bypass sharing when `SSL_CERT_FILE` or `SSL_CERT_DIR` is set, and continue reading custom CA bundles independently for every build.
## Testing
Add tests for overlapping loads, fresh trust after completion, and recovery from a panicking loader. Extend TLS handshake coverage to verify that replacing a custom CA file affects new configurations while existing configurations retain their trust, and that empty or removed files produce errors.
GitOrigin-RevId: 1465ef3faf82f53651d9dbfe314341b17346580b
## Why
Clients need a way to update individual turn metadata entries without replacing the existing client metadata map.
## What changed
Add the experimental `responsesapiClientMetadataPatch` field to `turn/start` and `turn/steer`. Patches add or overwrite entries while retaining other keys and apply after `responsesapiClientMetadata` when both are supplied. The existing field retains replacement semantics, including clearing unprotected entries with an empty map.
Continue protecting reserved metadata keys and preserving targeted `misalignment_override` continuations across updates.
## Testing
Extend the app-server metadata integration test to cover replacement and patch steering, patch precedence at turn start, preservation of unrelated entries during patches, and protection of targeted continuations.
GitOrigin-RevId: 8c4da3ba1b87329da20b5295846bdcf3a88126de
## Why
A queued skill refresh can outlive the workspace it was requested for when the working directory changes.
## What changed
- Refresh skills for the current working directory when the skills management popup closes.
- Ignore queued `ListSkills` commands whose directories do not include the current working directory.
- Require an explicit working directory when constructing `WorkspaceCommand` and always pass it to app-server command execution. Update Git and GitHub metadata probes to use the constructor.
## Testing
Extend regression tests to verify that closing skill management refreshes the configured working directory and that stale skill refreshes after a directory change do not issue a `skills/list` request.
GitOrigin-RevId: 47ad1d95930840b3f6f0e20d7d8fe8d025e789e6
## Why
The Agent Command Center does not open a workspace, so viewing it should not require consent for the launch directory.
## What changed
Skip startup folder consent when opening the agents overview, while preserving initialization for the embedded fallback. Check folder trust before starting the first task, including through `/new` after dismissing the overview. On Windows, retain the sandbox setup prompt after folder trust is granted.
## Testing
Add CLI tests for starting a task from an untrusted folder through the overview and through `/new` after dismissing it. A terminal snapshot verifies that the overview appears before folder consent.
GitOrigin-RevId: 129be14a354b8abde2e8430c81599e2064ccac87
## Why
Replaying an in-progress turn reset the TUI's `Working` timer to zero, hiding time already spent on the turn.
## What changed
Initialize the status timer from the turn's `started_at` timestamp when replaying turns or turn-start notifications. Keep the zero-time fallback when the timestamp is missing, and clamp future timestamps to zero elapsed time.
## Testing
Extend history replay tests to verify elapsed time for both thread snapshots and replayed in-progress turns, and normalize the timer in rendering snapshots.
GitOrigin-RevId: 36a48f43d0d7aa530f1bfe6dbefa9f0885cbd6c7
## What changed
- Preserve approval resolution sources through tool errors and tag cancelled MCP approvals with `error_type=approval`, `error_code=cancelled`, and `approval_source` (`guardian`, `user`, `hook`, or `unknown`). The source identifies the reviewer, not who caused cancellation.
- Record `context_changed` when validating a Guardian allow against changed authorization or review context, even when a concurrent stop or history reset determines the outcome. Retain the flag across retries and fresh-checkpoint recovery, and include it in the Guardian review counter.
GitOrigin-RevId: a19a986a7565f9a78a9bb2eaabdb5651834d28b8
## Why
Loading older history could place transcript entries before the `Thread forked from` notice, separating fork lineage from the session header.
## What changed
Treat fork lineage as a session prefix in both the TUI transcript and transcript overlay so older pages are inserted after it.
## Testing
Add regression tests for repeated history prepends in both paths, verifying that fork lineage stays first.
GitOrigin-RevId: 71497fb7ffa992c72ee08617d318aa3119e71275
## Why
An asynchronous approval currently waits for the redundant synchronous review to finish cancellation cleanup before returning a decision.
## What changed
Cancel the redundant review and let it drain under the parent's `ReviewerTasks` tracker so a current approval can return immediately. Revalidate the approval and check cancellation before approving the action. Hosts without a task tracker continue to wait for cleanup.
Keep the reviewer reservation held until cleanup completes, and let shutdown join the tracked attempt. Discard late results and evidence from the cancelled review.
## Testing
Add tests covering current, invalidated, and cancelled approvals while cleanup is blocked, suppression of late evidence, reviewer reservations during cleanup, and shutdown waiting for abandoned attempts.
GitOrigin-RevId: f227738e545243f99c19a6c557a78d330f9d2767
## What changed
Increase memory extension resource retention from 7 to 14 days before pruning.
## Testing
Update pruning and startup test fixtures for the 14-day retention window, including resources at the exact cutoff.
GitOrigin-RevId: 5044a1262c8806245d90d567cd84b21aa0d3da43
## Why
Collecting a diff previously launched a Git process for every untracked file at once, allowing process counts to grow with the number of files.
## What changed
Limit untracked-file diffs to eight concurrent operations per collection while preserving patch order and skipping failed file diffs. Concurrent collections each retain their own limit.
## Testing
Add tests for independent concurrency limits, failed-file handling, and patch order and application with tracked changes, binary files, and filenames containing spaces or a leading dash.
GitOrigin-RevId: 896e896eae62ba9b7acf3e8946c235fe725ced40
## Why
Windows MXC needs valid host startup variables, while an empty child environment must remain empty for the SDK to select Windows user-profile defaults.
## What changed
- Replace caller overrides of `SystemDrive` and `LOCALAPPDATA` case-insensitively with nonempty Unicode host values, failing before launch if either is unavailable.
- Track whether the original child environment was empty, ignoring launcher transport keys. Supply host `SystemRoot` for launcher bootstrap in that case, then clear the bootstrap environment before the SDK selects defaults.
## Testing
Extend transport tests to cover host-value replacement and preservation of empty child environments. Strengthen the PowerShell fallback RPC test to require `SystemDrive`, `LOCALAPPDATA`, `USERPROFILE`, and `PATH` in the child.
GitOrigin-RevId: a097e1079069ef897ebb5ba5e63546328c5faeaa
## Why
Compression replaces `.jsonl` rollout files with `.jsonl.zst` files, so checking only the original path can skip existing sessions. Compression can also replace a file between path lookup and canonicalization.
## What changed
- Resolve compressed rollout alternatives when selecting the latest local session.
- Retry rollout path resolution when files disappear during lookup or canonicalization.
## Testing
Extend coverage to verify latest-session filtering after startup compression and resuming a compressed rollout through its original relative `.jsonl` path with preserved turns.
GitOrigin-RevId: a4d5c399567ab4c7cd8aaa8b5f38821ee8b8d802
## Why
Doctor's rollout statistics only counted `.jsonl` files, omitting storage used by compressed `.jsonl.zst` rollouts.
## What changed
Recognize compressed rollouts when collecting active and archived file counts, total bytes, and average bytes. Count both physical files when plain and compressed representations coexist, while continuing to ignore unrelated files and compression temporary files.
## Testing
Extend the rollout statistics test to cover nested plain and compressed files, coexisting representations, archived compressed rollouts, and ignored files, with a snapshot of the reported counts and sizes.
GitOrigin-RevId: 46197f9741884668b50fb6a1d0a07060020f12ed
## Why
Filesystem lookups by thread or rollout ID check whether unrelated compressed rollouts have an uncompressed sibling. These checks are unnecessary when the filename does not match the requested ID.
## What changed
Apply the thread or rollout ID filter before resolving plain/compressed file precedence. Preserve preference for uncompressed files and selection of the newest rollout for a thread.
## Testing
Extend lookup tests to cover unrelated compressed files, uncompressed-file precedence, missing rollout IDs, and rollout ID tie-breaking for files with the same timestamp.
GitOrigin-RevId: 5bdb56ebec8031fceb5f6adbfcf644ad010e52f2
