## Why
The search tool integration test suite was disabled entirely on Windows.
## What changed
- Remove the suite-wide Windows exclusion and build test fixtures with automatic environment selection.
- Configure stdio MCP fixtures with environment-aware server paths and environment IDs for local and remote runs.
- Skip the three stdio MCP cases that still require a native Windows test server when running through Wine.

## Why
Executor skills required a `skills.list` lookup before their contents could be
read, even when the catalog already identified the skill.
## What changed
- Render executor skill catalog entries as package locators, including shortened
locators when skill roots are aliased.
- Tell the model to pass those packages directly to `skills.read`, while keeping
`skills.list` as the fallback when no package is available.
- Use the shorter package locators when applying the skills context budget.
## Testing
Update catalog, aliasing, budget-pressure, and selected-skill coverage, including
an executor package ID containing a literal backslash.
GitOrigin-RevId: 2ace5e527dc4f29651a8f3214475ccc90d52c73f
## What changed
- Represent MCP tool calls as approval actions and route them through the
session-level approval flow for permission hooks, reviewer selection,
rejection handling, and resolution telemetry.
- Preserve MCP-specific user prompts, session and persistent approval choices,
and the approval policy and reviewer captured for the tool call.
## Testing
- Add coverage for permission hooks resolving MCP calls before user or
automatic review, persistence choices, captured policy routing, and MCP turn
metadata with strict automatic review enabled.
GitOrigin-RevId: 8e134b3d17a19dc62b3b56076d2cd05a54c9f638
## What changed
- Include the connector ID, action name, and model in file creation requests for hosted app tool calls.
- Use the file size returned by upload finalization when available, while falling back to the local size for older server responses.
- Keep upload finalization requests empty for compatibility with older servers.
## Testing
- Cover hosted app upload metadata and legacy finalization responses.
GitOrigin-RevId: 1bc834736db4fe3515f8224965cde0e5d6955ca3
## What changed
Add integration coverage verifying that Guardian receives both the user prompt
and the outer code mode `exec` source when reviewing a nested escalated
`exec_command` call.
GitOrigin-RevId: e78e9d4d69e7ebccc935c548565a07600659f65a
## What changed
- Resolve user message admission when Core accepts the input as a new turn or a steer, without waiting for rollout persistence.
- Remove persistence- and hook-specific admission errors and task bookkeeping.
- Delete queued messages after Core accepts them for turn processing, including messages subsequently stopped by a prompt hook.
## Testing
- Update concurrent admission and queue service tests for acceptance-based admission.
GitOrigin-RevId: 7dcc311cfecd3d710733b420f2add546edb86153
## What changed
- Permit immediate user-message admission to start a turn when `Op::UserInput`
has no items. The turn can proceed with its generated environment context and
does not emit a user-message item.
- Continue rejecting empty input for persisted admission, where there is no
user message to persist.
## Testing
- Cover successful empty-input turn admission and completion.
- Cover prompt rejection of empty persisted admission.
GitOrigin-RevId: d534cf0e228e3bc77f45fe6d9bd25c9073216fbd
## What changed
- Detect executor-owned skill document reads and script executions across native and URI-based working directories.
- Match skills only within the active execution environment while preserving host skill detection for local commands.
- Emit resource-backed implicit invocation events and deduplicate repeated accesses within a turn.
## Testing
- Add unit coverage for document reads, script executions, and environment-scoped matching.
- Add an integration test for environment selection, resource-backed analytics, and repeated-access deduplication.
GitOrigin-RevId: f78a48c3a4766fe8775bd88926b45a76761f6af8
## Why
Threads that share an executor environment can require different capability roots and login-shell policies. Treating readiness configuration as executor-wide can expose one thread's settings to another.
## What changed
- Add `CodexThread::environment_ready` and `EnvironmentConfig` so hosts can install capability roots and login-shell policy for an exact thread, environment, and working-directory attachment.
- Validate attachment readiness updates, merge ready attachment roots with persisted thread roots, and refresh MCP capabilities when those roots change.
- Preserve installed environment policy across thread settings updates and child-thread inheritance while resetting it when the selected working directory changes.
## Testing
- Cover attachment config inheritance and reset behavior.
- Verify that threads sharing an executor retain independent model-visible capability roots and login-shell tool schemas across updates.
GitOrigin-RevId: 60e7a296b3e41b835b0413aa2837451e8a55c230
## What changed
- Emit skill invocation analytics when a resource-backed skill is explicitly selected or its main resource is successfully read from the first page.
- Preserve provider-supplied skill IDs and user scope when available, and derive a stable ID from the main resource otherwise.
- Deduplicate repeated implicit reads of the same main resource within a turn.
## Testing
- Extend the orchestrator skill integration test to cover explicit and implicit invocation events, stable fallback IDs, failed reads, and repeated-read deduplication.
GitOrigin-RevId: 7d8453b31b5a2205847e65cda2c46183d6c97b45
## What changed
- Set `store` to `false` for every Responses request, including requests sent
through Azure providers.
- Remove the provider-specific storage check and simplify request construction.
- Update the Azure request test to verify that storage is disabled while
prefixed item IDs remain unchanged.
GitOrigin-RevId: 1c71cb80880058cb26789112f03269b73f0645b9
## What changed
- Wrap response items with optional harness-owned metadata while keeping the persisted response payload shape backward compatible.
- Store compacted-history metadata in an aligned sidecar and reject malformed sidecars.
- Carry metadata through history normalization, compaction, resume, fork, truncation, migration, and rollout recording without sending it to model providers.
## Testing
- Cover legacy rollout compatibility, metadata serialization and validation, compaction retention, and resume/fork reconstruction.
GitOrigin-RevId: 17a6127c9048ff984cb4df4d97c0751a38c29f5f
## What changed
- Add a host-owned external auth source that runtime account APIs cannot replace,
clear, or log out, and keep its credentials process-local instead of writing
them to auth storage.
- Let configured providers classify refresh failures. Preserve cached credentials
after permanent reload failures while retaining transient behavior for runtime
providers.
- Compare external ChatGPT token data when detecting auth changes so a refreshed
access token is applied to a retried request.
## Testing
- Cover configured-auth immutability, process-local storage, permanent reload
failures, runtime error classification, and refreshed headers after a `401`.
GitOrigin-RevId: c6d70a39325c8ba6ca65ae68e12b55609f00a876
## What changed
- Add `inject_response_items_for_turn` for callers that inject Responses API
items immediately before admitting user input. It defers the rollout flush so
the injected items and user input are persisted together by turn admission.
- Keep `inject_response_items` behavior unchanged by flushing after it delegates
to the new helper.
- Update the turn-start persistence test to exercise the turn-aware path.
GitOrigin-RevId: 8349b65f937af2b2a95d36b3fd73d862d38e5fd9
## What changed
- Add `auto_review_enabled` to serialized turn metadata for regular and review turns.
- Derive the value from approval-policy routing and reserve the metadata key so client-provided metadata cannot override it.
## Testing
- Cover enabled metadata, reserved-key handling, Guardian review requests, and updated compaction request snapshots.
GitOrigin-RevId: 52773e2bf7d4be251f8466332de9f9c9869dd084
## Why
Cross-platform remote `apply_patch` calls were rejected when filesystem writes
were restricted because patch verification and writes could not be safely
performed against executor files.
## What changed
- Route intercepted and direct remote patches through the executor-managed
filesystem sandbox, including the configured workspace roots.
- Select the restricted-token sandbox for Windows executor paths when no
Windows sandbox level was configured.
- Fail closed when an executor cannot enforce the requested sandbox, and treat
executor-managed access failures as sandbox denials so approval can retry the
patch without sandboxing.
## Testing
- Cover sandboxed remote patches, denied writes, approval retries, Windows
sandbox selection, and executor filesystem enforcement.
GitOrigin-RevId: caddeed0b266c456a689080a14a3a58e2bd7887c
## What changed
- Remove effective-config lockfile export, replay, and validation from session startup.
- Remove the `debug.config_lockfile` settings and generated schema entries.
- Remove feature-config materialization helpers that were only used to create lockfiles.
GitOrigin-RevId: a8c07c1c06325b3ec3dae9a97c36c2488d37df25
## Why
Subagents should be able to use known HTTP MCP tool definitions without opening a connection until a tool is actually called.
## What changed
- Add streamable HTTP configurations to the process-scoped MCP tool catalog cache when their authentication identity can be derived safely.
- Fingerprint transport settings, relevant environment variables, protocol mode, plugin status, and client capabilities so catalogs are reused only across equivalent connections.
- Keep OAuth and other dynamically resolved credential configurations out of the shared cache.
## Testing
- Add an integration test proving that a subagent receives cached HTTP tools without reinitializing the server, then starts its own connection when it calls one.
GitOrigin-RevId: bb2787e29e9b71993def31aafd1f0d8f1b728d26
## What changed
- Reject invalid or unsupported image data before producing tool output, so
non-image file contents are not exposed through code mode.
- Preserve valid image bytes and metadata while leaving image preparation and
resizing to the history insertion path.
## Testing
- Cover invalid images in both code mode and standard `view_image` calls.
- Verify that code mode preserves PNG bytes, dimensions, EXIF orientation, and
metadata.
GitOrigin-RevId: 07343ed10b781d0ce0ffb5b24432658be4c046e3
## What changed
- Add `PersistContext` to the thread-store persistence contract so stores can
identify persistence requested immediately before model sampling. A
`TurnStart` request may be enqueued in the background when later flush and
shutdown operations fence it and report any failure; all other persistence
remains synchronous.
- Use the turn-start context only for the initial input of a regular turn, while
admission acknowledgments, steered input, and other persistence paths keep
the standard durability behavior.
- Flush pending metadata before turn-start persistence and ensure shutdown is
still attempted if that metadata update fails.
## Testing
- Verify that developer instructions and user input are persisted before the
model request completes for a default paginated-history thread.
GitOrigin-RevId: 162f0ec796a61aebe66ca0b909fbcccec3047b85
## Why
Background refreshes previously warmed only the on-disk cache, so new sessions in the same process continued using the startup snapshot.
## What changed
- Make `CloudConfigBundleLoader` retrieve the latest shared bundle on each configuration load.
- Update the in-memory bundle after successful refreshes while preserving the last successful bundle when a refresh fails.
- Stop refresh work when its loader is replaced or its final clone is dropped.
## Testing
- Cover refreshed requirements and managed configuration in later sessions.
- Cover concurrent initial loads, refresh failures and recovery, bundle clearing, and refresh-task cancellation.
GitOrigin-RevId: ae3d79b575bad71a1eed370cee6dc66dc022ffa8
## What changed
- Pass image bytes from `view_image` through unchanged for both direct and code-mode calls, leaving decoding and resizing to the shared history-insertion path.
- Represent invalid image data with the existing image-omission placeholder instead of returning a tool error.
## Testing
- Update the `view_image` integration test to cover placeholder output for invalid image data.
GitOrigin-RevId: 62863defd4815efb8a7725712fd583ad81db3fbb
## What changed
- Add `responses_api_metadata` for product-owned key/value metadata included in
every Responses API turn metadata payload, including parent and subagent
requests.
- Limit the map to 16 entries, ASCII identifier keys of at most 64 bytes, and
values of at most 128 bytes. Reject reserved Codex metadata keys and ignore
this setting in project-local configuration.
- Give configured product metadata precedence over app-server client metadata
while keeping it out of metadata sent to external MCP servers.
## Testing
- Cover reserved-key validation, metadata precedence, MCP isolation, and
propagation to parent and subagent Responses API requests.
GitOrigin-RevId: a7be798294fde25145ab375a468321bb4e4a49f1
## What changed
- Decode image data in the `view_image` handler and return a clear error for invalid or unsupported input.
- Re-encode code-mode images as PNG pixel data while preserving original image bytes for direct tool calls.
- Cover code-mode PNG output and rejection of invalid image data.
GitOrigin-RevId: 0a00e595ab749c19eab866a22f6577b6627e19f1
## What changed
- Parse safety-buffering payloads from typed `response.metadata` SSE events.
- Preserve the existing top-level `safety_buffering` field as the authoritative value when it is present, including when it is null or malformed.
- Continue applying the header-provided fallback model when the metadata payload omits `retry_model`.
## Testing
- Add parser coverage for metadata fallback, top-level precedence, and unrelated metadata events.
- Exercise metadata-based safety-buffering delivery through the core SSE integration test.
GitOrigin-RevId: 7dadfd54be28f2f33c2283de92fd49da0557d98a
## Why
Managed networking implicitly selected the elevated Windows sandbox backend,
even when the sandbox was configured to use a restricted token.
## What changed
- Select the Windows sandbox backend solely from `WindowsSandboxLevel`.
- Reject managed networking with a restricted-token sandbox before spawning a
process, since managed networking requires the elevated backend.
- Cover the rejection through sandbox preparation, unified exec, and Windows
sandbox session tests.
GitOrigin-RevId: 308858652d7b629af623d22896dafde3a23d3758
## What changed
- Add `codex-history` for model-history and persisted-rollout domain types, including `RolloutItem`, `RolloutLine`, `CompactedItem`, and initial/resumed history state.
- Re-export the persisted types from `codex-rollout` and update consumers to use the new crate boundary instead of `codex-protocol`.
- Preserve existing rollout serialization, including legacy numeric compacted-window IDs.
## Testing
- Add `codex-history` tests for rollout JSON round trips, compacted-history compatibility, persisted history modes, and multi-agent version selection.
GitOrigin-RevId: 944daa9297ddd231d3aebbdcb05fff4adf8b4e1b
## What changed
- Reject patches containing multiple operations whose paths resolve to the same file, such as `duplicate.txt` and `./duplicate.txt`.
- Preserve support for patches that update multiple distinct files.
## Testing
- Add CLI integration coverage for distinct updates and duplicate resolved paths.
GitOrigin-RevId: 0fb7f69ae31acc5c677268ffd9e38ad8d8314276
## What changed
- Cover non-blocking credential probes when the file or secrets store is locked, including retaining only a matching prior credential snapshot and recovering after the lock is released.
- Extend the streamable HTTP OAuth round trip to verify that user turns continue during store contention, newly discovered servers recover after contention, and logged-out servers do not reuse authenticated connections.
- Cover reconciliation of authentication failures and effective `Authorization` headers.
GitOrigin-RevId: 8e377644001bd0be04dc9f79841080094d09d199
## What changed
- Send Unix `execve` approvals intercepted by the zsh fork through the shared approval pipeline, including permission hooks, Guardian review, user prompts, and telemetry.
- Resolve the active turn and its auto-review setting when an intercepted command needs approval, so commands sent to persistent terminals use the current turn's reviewer.
- Give each intercepted command a distinct approval ID and propagate an aborted approval as a turn abort.
## Testing
- Cover Guardian review for intercepted `unified_exec` commands and persistent terminals across turns.
- Verify repeated identical intercepted commands receive separate user approvals.
GitOrigin-RevId: e6cccf160637e4246aff4714c22f08c90b65306d
## What changed
- Restore a V2 agent's inherited environment selections when reloading its
thread after residency eviction.
- Keep the restored execution environment and its tools available when the
agent receives a follow-up task.
## Testing
- Add an integration test that evicts and reloads a V2 agent, then verifies
its environment selection and `exec_command` tool are preserved.
GitOrigin-RevId: a5d4ad0fa465c717b32b7ae6807486429187a41d
## Why
The plugin and skill test suites were excluded wholesale on Windows, even though
most cases do not depend on POSIX behavior.
## What changed
- Make generated TOML and JSON fixtures escape Windows paths correctly.
- Use Windows-safe path canonicalization and normalize advertised skill paths.
- Select test environments through the environment-aware builders.
- Run the suites on Windows while narrowly skipping cases that execute POSIX
commands or require matching host and executor path conventions.
GitOrigin-RevId: aadf31013c2bf9bac728adc4dd96f572d4a3bf3f
## What changed
- Make `package` the only required argument to `skills.read`, resolving the
owning orchestrator or executor catalog automatically.
- Default omitted `resource` values to the package's main `SKILL.md`.
- Render orchestrator skills as package locators and instruct the model to read
them directly without first calling `skills.list`.
- Update skill extension and app-server coverage for direct main-resource
reads, referenced resources, aliases, and the revised tool schema.
GitOrigin-RevId: 9faf57a8d0935566a15094931eaabaa8f0613e9e
## What changed
- Add the `apply_patch_preserve_line_endings` feature, disabled by default, to
preserve CRLF, CR, and mixed line endings when `apply_patch` updates files.
- Apply the feature consistently to built-in patch handling and patches invoked
through shell, user-shell, unified-exec, and app-server command execution.
- Keep the active feature configuration authoritative over inherited, shell
snapshot, and client-provided environment values.
## Testing
- Cover line-ending behavior with the feature enabled and disabled for custom
tool calls, shell heredocs, command execution, and the `apply_patch` CLI.
GitOrigin-RevId: 531a7c66761959c650270559f57941929f03e6c4
## Why
Deferred environments can become ready after a turn starts. Guardian approval
reviews must use the environment selected for the current step so their working
directory and permission context are not taken from the stale turn snapshot.
## What changed
- Carry `StepContext` through tool execution and approval handling.
- Add a Guardian review context that pairs the parent turn with the current
step's environment snapshot.
- Use that snapshot for Guardian prompts, reviewer sessions, and delegated
reviewer threads while retaining turn-level fallbacks for callers without a
step context.
## Testing
Added an integration test that makes a deferred remote environment ready before
an escalated command and verifies Guardian receives that environment's working
directory and denied-read policy instead of the initial local environment's.
GitOrigin-RevId: 779096bc7d0e0c7453a009c02141029714b9b407
## Why
Hook configurations can mark command handlers as asynchronous, but Codex previously skipped those handlers outside `SessionEnd`.
## What changed
- Run asynchronous command hooks in the background with a per-session concurrency limit, while keeping `SessionEnd` hooks synchronous.
- Prevent asynchronous hooks from blocking, stopping, rewriting, or otherwise controlling the operation that launched them.
- Deliver warnings and additional context at safe turn boundaries: inject results into an active turn after sampling, or buffer them ahead of the next user prompt when the session is idle.
- Preserve in-flight hooks across configuration reloads, scope spilled output to the thread, and abort outstanding work during session shutdown.
## Testing
Add unit and integration coverage for background scheduling, concurrency, output parsing, active and idle result delivery, configuration reloads, and shutdown cleanup.
GitOrigin-RevId: 8094552e4afe7b47b09a61bb575bb20f4e491d8d
## What changed
- Filter saved `allow` prefix rules from the execution policy for cyber-specialized models and models listed in `auto_review.ignore_rules`, while preserving prompt, forbidden, network, and host-executable policy entries.
- Apply the filtered policy consistently to permission instructions, shell commands, unified exec, and the zsh-fork backend.
- Limit cyber-model command approvals to one-time decisions without proposing reusable policy amendments. General models continue to honor saved prefixes, including after switching models within a thread.
## Testing
- Add policy-level coverage for filtering allow-prefix rules while retaining restrictive and network rules.
- Add end-to-end coverage across shell and unified exec paths, zsh-fork execution, user and automatic review, and model switching.
GitOrigin-RevId: f3bd3872424291b12354ec415f33986ec369a368
## What changed
- Add the managed `auto_review.required_on_models` requirement, unioning model slugs across requirement layers and exposing the result through `configRequirements/read`.
- Force listed models to use `on-request` approvals with the `auto_review` reviewer. Downgrade Full Access to workspace-write when starting a protected session, and reject incompatible runtime overrides or use when automatic review is disabled.
- Preserve these protections across thread starts, resumes, forks, model changes, turn overrides, MCP approvals, and TUI session attachment.
## Testing
- Add coverage for layered model requirements and exact provider-alias matching.
- Add app-server tests for protected thread lifecycle operations, unsafe setting overrides, legacy thread upgrades, disabled automatic review, and requirements API output.
GitOrigin-RevId: c4b1d52c3b5b75e86880725412b8f0812e0dfcd9
## What changed
- Add the effective permission profile as `sandbox_mode` in turn metadata for regular, prewarm, compaction, and detached memory requests.
- Reserve `sandbox_mode` so client-provided metadata cannot override the computed value.
## Testing
- Cover metadata headers and request bodies for read-only and danger-full-access modes.
GitOrigin-RevId: 13c690cc99bc2691023f281ca527af049bb1286f
## What changed
- Add `HostSkillsSnapshot::load_skill_prompts` so the skills extension owns reading and rendering selected host skills.
- Keep explicit invocation telemetry, unreadable-skill warnings, plugin prompt ordering, and suppression of host prompts superseded by provider prompts.
- Remove the legacy prompt injection and fragment implementation from `codex-core-skills`.
## Testing
- Cover prompt truncation without an installed skills extension, skill/plugin ordering, selective provider supersession, unreadable skills, and contextual fragment detection.
GitOrigin-RevId: 9c8b84ad54b90d174abc287ab49cc5a231e9e1aa
## What changed
- Stop adding `code_mode_tool_names` to Responses Lite turn metadata.
- Keep `code_mode_tool_names` reserved so client metadata cannot reintroduce the removed, unbounded inventory.
- Use the opt-in `tool_namespaces_info` metadata, including each function's `code_mode_name`, when authoritative tool details are requested.
## Testing
- Update Responses Lite and code-mode tests to verify the opt-in namespace metadata and normalized code-mode names.
GitOrigin-RevId: cbfb9af984de71c7cc175d0cd47ae799a5275309
## What changed
- Add opt-in `tool_namespaces_info` metadata for Responses Lite turns when
`tool_registry.turn_metadata_includes_tool_info` is enabled.
- Describe each model-visible function's namespace, direct and deferred
exposure, Code Mode name, and harness or MCP ownership.
- Reject visible namespaces shared by different owners when strict collision
checking and tool inventory metadata are enabled.
- Keep tool inventories out of compatibility headers and metadata sent to MCP
servers.
## Testing
- Cover opt-in behavior, MCP exposure details, namespace ownership collisions,
reserved metadata handling, and Responses Lite request serialization.
GitOrigin-RevId: 6a6965d2ba98e29444fdfbb4ccec6aafcf0391e6
## Why
Long executor and orchestrator resource identifiers can consume enough of the
skills context budget to omit otherwise available skills.
## What changed
- Add source-aware root aliases for executor, orchestrator, and host skill
catalogs, including catalogs with a single shared root.
- Select the best combination of aliased catalogs under the shared metadata
budget while accounting for root tables and alias usage instructions.
- Explain how to expand shortened `skill://` locators and accept the resulting
description-shortening warning in app-server coverage.
## Testing
- Add rendering and production-turn coverage for singleton, executor,
orchestrator, host, and combined catalog aliases.
GitOrigin-RevId: c1bc1f3d371eae9526232674060235272cc28f16
## What changed
- Classify HTTP connection failures separately from other network errors without exposing request URLs.
- For sampling requests, retry connection failures with exponential delays from 5 to 60 seconds and show a `Reconnecting... waiting for network` stream error.
- Preserve the normal stream retry budget while waiting for the provider to become reachable. Keep the existing bounded retry behavior for other retryable errors.
## Testing
- Verify connection errors are classified without leaking URL contents.
- Verify a turn recovers after its provider becomes reachable and still applies the configured retry limit to a subsequent incomplete stream.
GitOrigin-RevId: 646553290c865a1332abd30c4a64ed9266bbfc6f
## Why
Interrupting a turn should also stop code-mode work that the turn left running.
## What changed
- Add the disabled-by-default `code_mode_interrupt` feature.
- When an interrupted turn has the feature enabled, terminate all active code-mode cells and propagate cancellation through nested tool calls.
- Keep the reusable code-mode session alive so its stored state remains available to later turns.
## Testing
Add an integration test that interrupts a long-running nested tool, verifies that active and background cells are removed, and confirms that session state is preserved.
GitOrigin-RevId: 2b8634776a89b636318a39b9e9ad2eefc07cead8
## What changed
- Preserve executor-native working directories, workspace roots, and permission profiles when preparing remote `exec_command` requests instead of resolving them through the host platform.
- Send sandbox intent to the remote executor, including a restricted-token default for Windows executors and `-NoProfile` for elevated PowerShell commands.
- Reject intercepted cross-platform `apply_patch` commands when filesystem writes are restricted, while continuing to allow them for unsandboxed or full-disk-write profiles.
## Testing
Extended remote unified-exec coverage for foreign Windows workspaces, elevated PowerShell, sandbox metadata, and restricted and unrestricted intercepted patches.
GitOrigin-RevId: 9fd328879fa2c15594fd58e40b6b32e8ba0847e7
## What changed
- Add the tool call ID to `_meta.callId` for every MCP tool request.
- Rename `features.tool_registry.include_tool_metadata` to
`features.tool_registry.turn_metadata_includes_tool_info` to clarify that the
setting controls authoritative tool information in per-turn metadata.
- Update config parsing, schema generation, and session config locking for the
renamed setting.
## Testing
- Cover `callId` metadata for custom, plugin, and Codex Apps MCP calls.
- Update strict-config, config-loading, feature-config, and config-lock tests for
the renamed setting.
GitOrigin-RevId: ac0e58c489b03bd9b55a356f545de86c8ecaf865
## Why
Plugin suggestions should report skills only when the plugin has an enabled skill.
## What changed
- Load suggestion metadata through the shared plugin skill-root loader.
- Apply skill configuration when setting `has_skills` on suggestion candidates.
## Testing
Added coverage for local plugin suggestions with the plugin skill both enabled and disabled.
GitOrigin-RevId: bceb14528c9042b474eaad6efaf919bef72e0ca4
## Why
Persisted base instructions need to retain whether they were explicitly customized or generated from a model template. Without that distinction, forks and config-lock replays can treat model-generated instructions as custom and keep the wrong template after a model or personality change.
## What changed
- Record custom or model provenance with base instructions in rollouts and config locks.
- Preserve custom instructions across model changes, while allowing model-generated instructions to follow the selected model and personality.
- Keep legacy rollouts without provenance compatible and propagate provenance through forks and spawned agents.
## Testing
- Cover provenance serialization and legacy rollout decoding.
- Cover role personality changes, forked model changes, config-lock replay, and multi-agent configuration.
GitOrigin-RevId: 801c26559835f558027ce5112700c0cd31fcb21b
