## What changed
- Add environment-provided MCP restrictions for configured and plugin-provided servers.
- Disable attachment-scoped servers while their environment configuration is pending, failed, or unselected, while preserving selected-plugin access and the controller-owned Apps server.
- Apply the resolved policy to runtime startup, model tool exposure, telemetry, OAuth flows, and skill dependency installation.
## Testing
- Cover policy filtering for configured and plugin servers, environment state transitions, Apps ownership, and managed OAuth rejection.
GitOrigin-RevId: 7ca5d4dda14068e758497f88835d5cba685e159e
## What changed
- Execute hook-triggered MCP calls through the runtime's latest connection set instead of preparing a separate catalog-bound call.
- Keep hook calls from waiting for server startup or reconnecting, and reject disconnected servers immediately.
- Apply the shorter of the hook-requested timeout and the server's configured tool timeout.
## Testing
- Update connection manager tests to cover non-waiting calls and disabled tool filters.
GitOrigin-RevId: 3166b2d1e26d9ae2b8b3a648b4d0897cc260eb93
## What changed
- Validate externally supplied header credentials against configured ChatGPT workspace restrictions using their `chatgpt-account-id` header.
- Reject header credentials with a missing or disallowed account ID, including credentials returned during refresh, without replacing the previously cached authentication.
- Document that identity headers must be bound to validated credentials because Codex uses them for managed authentication policy.
## Testing
- Add coverage for allowed, disallowed, and missing account IDs.
- Add coverage for rejecting a refresh that changes to a disallowed workspace.
GitOrigin-RevId: 3e3db2607cd8f9f1b8000472342e42e4b1cf00b2
## What changed
- Cover same-origin redirects for protected-resource and authorization-server metadata.
- Verify that cross-origin redirects are rejected before contacting their targets and that redirect cycles fail within a bounded timeout.
- Exercise issuer validation and resource-header isolation for both direct and redirected metadata across legacy and Agent Plugin discovery modes.
- Reuse the test environment's local HTTP client throughout the discovery tests.
GitOrigin-RevId: bd12ac232c3b020a1c098a413361f8e205699699
## What changed
- Add `send_user_message_async` for root agents when the async-message feature is enabled and the model advertises tool support.
- Emit the supplied text as an asynchronous agent message and immediately return an accepted result so the turn can continue.
- Keep the user-visible update out of the model's input context.
## Testing
- Add an integration test covering tool registration, item events, continued turn execution, and model context.
GitOrigin-RevId: 13d5168cb8cd6742db17bb74a15c910994e9c98b
## What changed
- Recognize `edu_plus` and `edu_pro` as distinct education workspace plans across authentication, backend rate-limit mapping, and app-server account schemas.
- Include both plans in cloud configuration eligibility and use the education usage-limit behavior.
- Display the plans as `Edu Plus` and `Edu Pro` in the TUI status view.
## Testing
- Cover parsing, workspace classification, account and rate-limit responses, cloud configuration eligibility, usage-limit messages, and TUI display names for the new variants.
GitOrigin-RevId: bf8add780ae03a3c6d10c4f4afa0da262c37928e
## Why
Selecting only the newest entries changes the retained transcript prefix whenever a new entry arrives, reducing cache stability.
## What changed
- Replay non-user transcript entries through a bounded buffer and evict half of the applicable pool when an entry or token limit overflows.
- Keep message and tool token budgets independent, and reject entries that cannot fit without evicting retained evidence.
- Preserve user-message selection and emit retained entries in transcript order.
## Testing
Added coverage for stable tool prefixes, message-budget overflow, rejected messages, and chunked entry-count eviction.
GitOrigin-RevId: e6181f5a229a6de06c7ef5db21a5c74980a53e97
## What changed
- Capture the process environment when the hook registry is created and reuse
that snapshot across configuration reloads.
- Clear the live environment before launching command hooks and legacy notify
commands, then apply hook-specific overrides and scrub non-inheritable
credentials.
- Resolve the default shell from the captured environment.
## Testing
Add coverage for snapshot replay, overrides, credential scrubbing, default
shell selection, non-Unicode values, and runtime reconfiguration.
GitOrigin-RevId: fee60c88e842980cdfc1bd49b14b62b9a56b08cd
## What changed
- Add an optional `delivery` field to agent message events and app-server
`agentMessage` items, with `"async"` identifying a user-visible message sent
without ending the current turn.
- Preserve the marker through legacy event conversion, thread history
materialization, replay, and generated JSON and TypeScript schemas.
- Require delivery of async agent message completion notifications on the
in-process app-server transport.
## Testing
- Cover preservation of async delivery metadata in thread history.
- Cover delivery-required classification for async agent messages.
GitOrigin-RevId: f92ba25de1293ee271404badfdf0d117d6530329
## Why
An unfamiliar executable can ignore its arguments, so trust in an apparent
inner command must not implicitly trust the executable that runs it.
## What changed
- Evaluate unfamiliar shell executables alongside their parsed commands when
determining unified exec approval requirements. Inner commands can add
restrictions, but cannot grant trust to the executable.
- Include the executable in reusable approval keys so approval for one custom
shell does not apply to another.
- Parse literal PowerShell scripts without launching the requested executable,
preserving command policy checks before approval.
## Testing
Add cross-platform coverage for spoofed shell paths, allowed and forbidden
inner commands, explicit custom-shell approval, and session approval isolation.
GitOrigin-RevId: 0dd2c7e9a2ac30965ef5fe5de1a8d2968bb5f9d0
## What changed
- Carry selected plugin identities from MCP discovery into per-turn extension data, limited to capability roots that are ready for the turn.
- Annotate executor skill catalog entries with the matching plugin ID and `user` scope.
- Include that attribution in `skill_invocation` analytics for both explicit and implicit executor skill invocations.
## Testing
- Extend the executor skills app-server test to verify plugin ID, skill scope, and invocation type for explicit and implicit analytics events.
GitOrigin-RevId: 9345600ae29bcb8eb894fffd2d6f7b05f22ebf74
## What changed
- Treat configuration, action serialization, thread lookup, and classification errors as elevated risk instead of retaining a prior low-risk result.
- Track asynchronous scoring failures separately from completed scores so approval review falls back to strict review when the latest tool call could not be scored.
- Preserve newer classification results when recording a fail-closed score.
## Testing
- Add coverage for each failure path and for ordering fail-closed scores with concurrent classifications.
GitOrigin-RevId: 7012f078a24031848f2943354a206866286ad9f4
## What changed
- Include legacy managed-file and MDM settings when resolving project root markers and project trust in both canonical and executor-local config loads.
- Preserve the existing managed-layer precedence in the final config stack and resolve managed relative paths against the same bases used by the final loader.
- Update explicit-untrusted warnings to describe the effective configuration and direct users to an administrator when the setting is managed.
## Testing
- Cover managed root markers, managed trust overrides, MDM precedence, app-server config reads, and the remote TUI warning.
GitOrigin-RevId: 9b5ddd54b4530f73589d6842a15cbab7e6d6bbb9
## What changed
- Stop writing Guardian v2 security risk scores to rollout history.
- Treat resumed and forked threads as having no previous Guardian score, so their
first tool approval is classified and reviewed normally.
- Remove the now-unused `codex-history` dependency from the Guardian v2
extension.
## Testing
- Update app-server coverage for new, resumed, and forked threads to wait for
classification completion and verify the expected approval reviews.
GitOrigin-RevId: 74d9caa903a1ff9d38e577b4697b5f8970f11ebb
## What changed
- Pass session-attributed extension metrics to the Guardian v2 sampler.
- Record `codex.guardian_v2.classification.token_usage` histograms for total, input, cached input, cache-write input, non-cached input, output, and reasoning output tokens.
- Preserve token accounting when streamed JSON produces an early score by recording usage from the terminal response in the background.
## Testing
- Cover token metrics through the Guardian v2 extension and the sampler's early-score path.
GitOrigin-RevId: 04fadc07f3b9cbe83f9fa3737536860b5cf5b4be
## What changed
- Add `NODE_REPL_AUTH_TOKEN` to the environment variables that model-reachable child processes cannot inherit.
- Remove the variable case-insensitively after shell environment policy overrides and from explicitly configured child command environments.
- Extend the environment scrubber tests to cover inherited and configured forms of the token.
GitOrigin-RevId: 716c65e0a9e222f705c226b7c86545251d3ea580
## Why
Agent roles should customize a child agent without expanding the authority or changing the provider configuration inherited from its parent session.
## What changed
- Apply only supported role overrides for model behavior, developer instructions, personality, service tier, and capability reductions.
- Preserve parent-owned permissions, model providers, endpoints, MCP servers, notifications, and other unrestricted configuration.
- Keep managed feature requirements effective when a role disables capabilities, and reject symlinked user role files.
- Use the same bounded role application path for both multi-agent implementations and resumed agents.
## Testing
Add coverage for authority preservation, managed feature requirements, symlink rejection, provider inheritance, and provider routing after resume.
GitOrigin-RevId: c528d615b691f9c02bfbc21154d514ea07743010
## What changed
- Add `--package-version` to set the version written to `codex-package.json`, while retaining the workspace package version as the default.
- Reject values that are not runtime-compatible semantic versions, including overflowing numeric components and numeric prerelease identifiers with leading zeroes.
- Document the new option.
## Testing
- Add unit coverage for valid release, prerelease, and build versions, plus malformed and out-of-range values.
GitOrigin-RevId: cee996a6721e3fac9bd88f0bc0302a7ec7d2b2fb
## What changed
- Execute `mcp_tool` hook handlers through the session's shared MCP runtime, including managed hook configurations.
- Restrict hook calls to already-connected, cataloged, and policy-allowed tools. Unavailable servers fail immediately without starting or reconnecting them.
- Pass session metadata to hook tools, cap hook timeouts by the server timeout, and invoke hooks without model-tool approval or recursive hook dispatch.
- Record handler type and execution mode in hook telemetry, and mark memory as externally influenced after successful or blocking MCP hooks when configured.
## Testing
- Added end-to-end coverage for prompt interpolation, hidden tools, blocking decisions, unavailable servers, thread metadata, approval bypass, and memory-mode handling.
- Added MCP runtime coverage for startup readiness, tool filters, catalog revisions, and managed connector policy.
GitOrigin-RevId: 1647cb801ebc5fa385c7bda9d9c266a389c611b8
## What changed
- Increase the default bounded log queue capacity from 512 to 2,048 entries.
- Raise the default insert batch size from 128 to 512 entries.
- Extend the default periodic flush interval from 2 to 10 seconds.
GitOrigin-RevId: e96be0996152b4a2a84d88c23d36959436685682
## Why
`codex-http-client` is the intended owner of `reqwest`, while direct first-party
dependencies are tracked as migration debt.
## What changed
- Build app-server test HTTP clients through `HttpClientBuilder`.
- Use `http` and `url` types directly where only protocol types are needed.
- Remove `reqwest` from `codex-app-server` and its temporary dependency-policy
exception.
GitOrigin-RevId: ff9f14a54bc20ec1ea39050bbe08c381ee376119
## What changed
- Report the configured Windows sandbox backend and whether denied-read restrictions are active.
- Diagnose incompatible backend policy, incomplete or failed elevated sandbox provisioning, unreadable setup failure reports, and missing, locked, disabled, or expired sandbox accounts.
- Provide issue-specific remediation and promote the sandbox check status and summary to the highest detected severity.
- Export the Windows sandbox setup data needed by the diagnostic check.
## Testing
- Cover missing Linux helpers and malformed or oversized Windows setup failure reports.
- Cover a recorded Windows sandbox refresh failure after setup completed.
GitOrigin-RevId: e965b703578a5c0597dcce9f836d2e1f510ad0c8
## What changed
- Add the under-development `send_async_message` feature, disabled by default.
- Expose the feature key in the generated configuration schema.
GitOrigin-RevId: dd27483f2ef802dba49e47f3ce03146ee6a58f1e
## Why
Submitting a diagnostic report could appear successful without confirming that Sentry accepted the upload, leaving callers unable to detect transport or HTTP failures.
## What changed
- Send report envelopes through the route-aware HTTP client and await the response.
- Reject redirects, propagate transport and non-success HTTP responses, and include the full error chain in upload JSON-RPC errors.
- Add structured logs for upload attempts, successes, and failures without including report contents.
## Testing
Added coverage for successful uploads, rejected responses, blocked redirects, transport failures, and app-server JSON-RPC error reporting.
GitOrigin-RevId: 07b5cfccd7a65f35d51a720537d2cd8962ed6cdb
## What changed
- Show a description and the destination paths affected by each file-change approval.
- Include both source and target paths for moves, format cross-platform paths for display, and show `unavailable` when change details are missing.
- Recover file changes from buffered events and thread snapshots so live and replayed approvals retain their destination details.
## Testing
- Add coverage for active and replayed approvals, moved and cross-platform paths, and the missing-destination fallback.
GitOrigin-RevId: 24f90b313fd8643f90cbead1504c788b140d7fed
## Why
When a local proxy request disconnects before network approval completes, the
owning tool call needs a model-visible explanation instead of remaining tied to
the abandoned request.
## What changed
- Track disconnect timing while plain HTTP and CONNECT requests await policy
decisions.
- Cancel the owning execution and report how long the request waited when it
disconnects before approval completes.
- Preserve an explicit approval outcome when disconnect cleanup runs afterward.
## Testing
Added unit coverage for disconnect tracking and outcome precedence, plus
end-to-end coverage for plain HTTP and CONNECT requests.
GitOrigin-RevId: b354b29bbe86f38e252fcaf529541f177480136b
## Why
The secure devcontainer's firewall does not apply its domain allowlist to DNS
traffic, so it does not provide secure DNS resolution for untrusted code.
## What changed
Document the DNS exfiltration risk, limit the devcontainer recommendation to
trusted repositories, and describe filtering DNS through a restricted resolver
as a partial mitigation. Clarify that allowlisted HTTPS destinations remain a
possible exfiltration path.
GitOrigin-RevId: 73cc7d29f8de17013c01411f8c20b8b5e1199b24
## What changed
- Add a public `snapshot_script` helper to `codex-shell-command` for Bash,
Zsh, POSIX shell, and PowerShell, returning `None` for Command Prompt.
- Update `codex-core` and its shell snapshot tests to use the shared helper
without changing snapshot behavior.
GitOrigin-RevId: 779b9dc964635b717922ea9f5646b94c4dbb0da1
## Why
Windows sandbox preflight could report success when applying a deny ACE failed,
leaving a detected world-writable path without the intended capability
restriction.
## What changed
- Return errors from `SetEntriesInAclW` and `SetNamedSecurityInfoW`, including the
affected path in ACL API errors.
- Attempt every flagged path, aggregate deny-ACE failures, and fail preflight
after logging them.
- Preserve cleanup of security descriptors and newly allocated ACLs on failure.
## Testing
Added tests that verify ACL API failures are returned and that preflight keeps
processing remaining paths before propagating an error.
GitOrigin-RevId: e2be1c70f72840046dc55760364de7bcf3b1bdc9
## Why
Thread settings could replace an owner-provided environment configuration with
`FromThread`, allowing the thread to take ownership of that configuration.
## What changed
Reject environment settings updates that change an existing owner-provided
configuration to `FromThread`.
## Testing
Cover preview and turn settings updates for pending, ready, and failed
owner-provided environments.
GitOrigin-RevId: c516954819447ceb29e2ff9f29fe781ca101ae54
## What changed
- Add experimental `account/bedrock/discover` and `account/bedrock/setup`
requests to the app-server protocol.
- Define discovery results for AWS profiles and environment credentials, plus
setup inputs for profiles, environment credentials, and access keys.
- Export the new types in the experimental protocol schema. The app server
currently returns `method not found` for both requests because setup is not
yet implemented.
GitOrigin-RevId: 656b4bc11231a417e97041068cecc5dc692786e3
## What changed
- Let model providers identify recoverable authentication errors and refresh their own authentication state before falling back to `AuthManager` recovery.
- Apply provider recovery to both HTTP and WebSocket response requests, with at most one provider-owned recovery attempt per request.
- Preserve existing `401 Unauthorized` handling as the default for providers that do not customize recovery.
## Testing
- Add coverage for successful and failed provider recovery, including the single-attempt bound and preservation of the original unauthorized error.
GitOrigin-RevId: 9a737e3be96354699586f97dd88e544a45082969
## Why
Legacy threads and paginated threads read their displayed names from different metadata. Moving a rollout to paginated history must carry over its legacy-visible name so renamed threads do not lose it.
## What changed
- Load legacy indexed names once for an apply run.
- When promoting a thread, preserve an existing canonical name or copy its distinct legacy title, falling back to the legacy name index.
- Repair missing names when migration encounters an already-paginated rollout.
## Testing
Added migration tests covering preservation from both legacy name sources and repair on a rerun.
GitOrigin-RevId: 5fc526570b1cf358a159ef174c159ac091ccc40f
## What changed
- Add a dedicated developer policy for Guardian reviews of Node REPL browser and computer-use actions.
- Inject the policy once before the first eligible Node REPL approval and retain it when the reviewer session is reused.
- Include Node REPL policy eligibility in the reviewer reuse key so sessions are not reused across incompatible model settings.
- Keep the approval request itself on the generic planned-action format.
## Testing
- Cover first-action injection, reuse after a shell review, repeated Node REPL reviews, and ineligible parent models through the production approval path.
GitOrigin-RevId: bfce190ff8599788aa85e388cc6a959d27fb489c
## Why
A stored permission grant may allow access to a parent while explicitly denying
a child path. A later request for that child must not be treated as already
approved by the broader parent grant.
## What changed
- Compare materialized permission profiles without intersecting away denied or
reopened paths before deciding that a request is preapproved.
- Execute preapproved commands with the stored grant itself so its denied paths
remain enforced.
- Fail closed when permission profiles cannot be materialized.
## Testing
Added unit and integration coverage for turn and session grants across
`exec_command`, `shell_command`, and `apply_patch`, including approval-disabled
and `Never` approval modes.
GitOrigin-RevId: 5455880328a89c7958f859c7ce87805dff9704fb
## What changed
- Replace the minimal default classifier prompt with predictive security-review guidance covering authorization, action risk, untrusted evidence, and browser or computer use.
- Trigger full Guardian review at an `action_risk` score of `0.5` or higher for the new default prompt, while retaining the `0.8` calibration for custom and model-provided prompts unless they specify a threshold.
- Render security policy configuration into prompt templates before enforcing the classifier instruction token limit. Prompts without the policy placeholder retain the existing append-and-truncate behavior.
## Testing
- Cover default, custom, and model-provided prompt thresholds and precedence.
- Verify policy substitution, truncation, sampling requests, and full review at the threshold boundary.
GitOrigin-RevId: 7aad9e2d8c9fbea453dc52147a3d0a46bf191aec
## Why
The Windows PTY implementation probed `conpty.dll` by bare name. Windows could
resolve that lookup to a DLL in the process current directory and load it when
creating a pseudoconsole.
## What changed
Resolve the ConPTY entry points from `kernel32.dll` without probing
`conpty.dll`.
## Testing
Add a Windows regression test that places a compatible `conpty.dll` in the
current directory, creates a ConPTY, and verifies that the DLL was not loaded.
GitOrigin-RevId: be78974362a99dce0c18186cf3e7bbd86a8de73c
## Why
When the app server reports a misalignment policy violation, the TUI must stop the affected chat rather than allow more work to continue in it.
## What changed
- Finalize the active turn, clear queued and draft input, disable the composer, and reject further operations and interactive requests for the stopped chat.
- Interrupt an active side conversation when its parent reports the violation, and prevent queued turns, forks, approvals, or goal resumption from restarting work.
- Show a non-dismissible precaution view that directs users to start a new chat or resume another one, with agent command center navigation for remote sessions.
## Testing
Added coverage for stopped-chat behavior, parent/side-thread handling, blocked goal resumption, navigation actions, and narrow and remote-session rendering.
GitOrigin-RevId: 0268c46a19294a17765ea4099f389f15ffaaf030
## What changed
- Return retained unified-exec output as one contiguous byte buffer.
- Use the buffer directly for sandbox-denial checks, removing intermediate
chunk aggregation and an unnecessary owned string conversion.
- Update the output-retention test to assert the flattened snapshot.
GitOrigin-RevId: 84eacee0166b86d3cb2d6a37e96125977fad0267
## What changed
- Reconnect frameless bidirectional WebRTC sideband sockets after unexpected transport loss with capped exponential backoff.
- Preserve pending text or handoff output and bounded transcript state across reconnects.
- Treat `404 Not Found` and `410 Gone` handshake responses as terminal session completion, and preserve HTTP status information from failed WebSocket handshakes.
- Bound Realtime delegation input and transcript fields while retaining the most relevant portion of each.
## Testing
- Add unit coverage for reconnect backoff, terminal status handling, transport error classification, transcript continuity and truncation, and pending outbound messages.
- Add an end-to-end WebRTC conversation test covering an unclean disconnect, reconnect, transcript reconciliation, outbound progress during sustained inbound traffic, and terminal session completion.
GitOrigin-RevId: 544fd7e542c3434d0bb42cfbcc7143604419a037
## Why
SQLite metadata can identify a rollout through a non-canonical path. When that
path resolves to a rollout already found on disk, archive and unarchive
operations could schedule the same source file to be moved twice.
## What changed
- Deduplicate archive and unarchive moves by canonical source path.
- Cover both operations with metadata-backed tests that use equivalent rollout
paths.
GitOrigin-RevId: d190915264214413667fc2c83d360a7e8504d0aa
## What changed
- Add `codex exec-server forward --connect ws://HOST:PORT` to register an
existing WebSocket exec-server as a remote environment.
- Open a separate destination WebSocket for each authenticated Noise relay
stream and forward complete payloads unchanged in both directions.
- Preserve large messages through WebSocket fragmentation and coordinate
disconnects, close acknowledgements, and pending output delivery.
## Testing
- Cover CLI validation, opaque payload forwarding, disconnect handling, and
destination close behavior.
- Verify commands and large file transfers through the complete relay and
forwarding path.
GitOrigin-RevId: 6e2dccff05b9e3571865611f4d432b0e2b4cdbac
## Why
Guardian sampling uses a pool of WebSockets, while the bridge routes each
connection by thread ID. Each socket therefore needs its own identity instead
of reusing the source thread ID across the pool.
## What changed
- Generate a classifier thread ID for every pooled connection and use it for
request, window, and subagent attribution.
- Preserve the originating thread ID in turn metadata alongside the Guardian
classifier request kind.
- Build request metadata after leasing a connection so retries use the identity
of the socket that carries the request.
## Testing
- Cover unique identities across pooled and replacement connections.
- Verify classifier attribution metadata for extension requests and retries.
GitOrigin-RevId: 1c36207125157ff05cab9487a2fa37bf85e5fdd8
## What changed
- Add an optional `connectorId` to `mcpServer/resource/read`.
- Forward the selected connector through `x-codex-turn-metadata` for threaded and threadless resource reads, restricting hosted app resources to that connector.
- Update the generated protocol schemas and app-server documentation.
GitOrigin-RevId: 5cc94d703abbbb6086665910c1c9ed5dc7075210
## What changed
- Add `intersect_effective_permission_profiles` to derive the permissions shared by an authority profile and a requested profile.
- Preserve the more restrictive filesystem access, read denials, protected metadata paths, temporary-directory access, and network policy.
- Canonicalize concrete paths so symlinks cannot expand authority, and fail closed for policy shapes that cannot be intersected safely.
## Testing
Add coverage for workspace intersections, nested carveouts, deny patterns, unsupported policies, temporary-directory restrictions, symlink escapes, and macOS path aliases.
GitOrigin-RevId: a35bdc47e41afad13630f92c032514b300c14a0d
## What changed
- Emit a `codex.guardian_v2.classification` counter for each classification.
- Record classification latency in `codex.guardian_v2.classification.duration_ms`.
- Tag both metrics with `success`, `failure`, or `superseded` outcomes.
## Testing
- Verify metrics for successful classification and fail-closed handling.
GitOrigin-RevId: 021702f3b26565d6da5708d2b8f1f8881942a441
## What changed
- Give plugin managers for the same cache root a shared semaphore that permits
only one background installed-plugin bundle sync at a time.
- Hold the permit for the lifetime of the spawned sync task and refresh the
installed-plugin cache after a successful local cache change.
## Testing
- Add a test that starts bundle syncs from two plugin managers sharing a Codex
home and verifies that only one request is made.
GitOrigin-RevId: 86c39476c3a9015b9862ab75e8f11f110b0284fc
## What changed
- Add a `NoiseStreamHandler` abstraction that owns payload encoding, decoding,
and connection processing while the virtual stream handles framing,
encryption, and multiplexing.
- Reassemble authenticated payloads as opaque bytes, with the existing
JSON-RPC processor supplied as a handler implementation.
- Have the physical relay send a reset after the current stream instance
closes, including when its processor exits before the writer task.
## Testing
- Verify local JSON-RPC decoding creates the queued request span before queue
admission.
- Verify a processor exit resets the corresponding Noise harness stream.
GitOrigin-RevId: 270befcc8bfbf27e46c84d6a2c6e349cb98ea3f8
## Why
`node_repl` screenshots are nested tool results and do not appear in the parent
conversation history, so Guardian v2 transcript image collection could miss
them.
## What changed
- Allow Guardian v2 to enable bounded, thread-scoped `node_repl` image capture
when transcript images are configured.
- Add retained `node_repl` screenshots to review requests when transcript
sources include tool outputs, while deduplicating images and keeping them out
of the parent turn input.
## Testing
- Add an integration test covering screenshot capture without the synchronous
Guardian transcript feature flags and verifying that screenshots stay out of
the parent request.
GitOrigin-RevId: 5f70c5f2e80389aa8b2a286c3b7f9b1104865486
