## What changed
- Add `features.guardianv2.sync_elastic_budgeting` and `sync_elastic_sections` to configure section minimums, per-entry token caps, and optional section maximums. Require and validate section limits when enabled.
- Use the selected budgeting policy consistently for history capture, resume, prompt preparation, and review input budgeting. Keep fixed budgeting as the default.
## Testing
Add configuration validation tests, capture-and-resume coverage for both budgeting modes, and a request-history snapshot verifying retained instructions and transcript section limits.
GitOrigin-RevId: c7b0bdfd3e0e008d75c4d8a204959bcc58eb1bf8
## What changed
Add the default-off `suppress_model_change_announcements` feature flag. When enabled, incremental context updates omit the model ID announcement after a model switch while still delivering changed base instructions and tool definitions.
Advance the model snapshot even when a switch emits no context update, so subsequent turns recognize the current model.
## Testing
Add coverage for omitted and explicit flag values, snapshot advancement without repeated updates, and request history across model switches, repeated turns, and compaction with announcements suppressed.
GitOrigin-RevId: 89c70f1e9d7981fd945fb8e41b1f98492717a07e
## What changed
Register `guardianv3` as an under-development feature disabled by default. Accept either a boolean toggle or a table with an optional `enabled` field, and include both forms in the configuration schema.
## Testing
Add coverage for boolean and table configuration, default behavior, and profile overrides, including inheritance when a profile omits `enabled`.
GitOrigin-RevId: 75333be61b2e336e22fef907d6363b70f9f7225b
## What changed
Add `RuntimeAuthProvider` to resolve request authentication through the runtime auth manager. Support `dual_header` mode, which sends a bearer credential alongside `x-openai-agent-assertion`, and `assertion_only` mode, which uses `Authorization: AgentAssertion …`.
Replace stale authentication headers and sign a fresh assertion for each request attempt. Propagate registration failures without falling back to credential-only authentication, preserving policy errors and classifying transport failures, rate limits, and server errors as transient.
Add the disabled-by-default `features.runtime_agent_instances` configuration with independent `enabled` and `mode` settings, schema support, and structured override merging. Selecting a mode alone does not enable the feature.
## Testing
Add coverage for both modes with API key and ChatGPT credentials, stale header replacement, fresh assertions, credential refresh without runtime replacement, registration failures, and configuration parsing and merging.
GitOrigin-RevId: 9e93d25762600f0ff592c5248fe4c8c2c8182c8d
## 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
## What changed
Add `features.multi_agent_v2.disable_native_tools` to hide native multi-agent tools while keeping the V2 runtime and its instructions enabled for host-provided tools. The option defaults to `false`, preserving existing tool exposure.
## Testing
Extend configuration parsing tests for the new option and parameterize the multi-agent catalog scenario to cover both settings. Add a snapshot showing native tools are absent while the V2 runtime and instructions remain enabled.
GitOrigin-RevId: 21a53584d2395bb678813c876a8b7927bea61c90
## What changed
Add `preserve_fork_prefix` to the multi-agent v2 configuration, defaulting to `false`. When enabled, full forks retain the parent's model-visible history, including commentary and tool records, and append the child's instructions. Legacy compaction without a reusable context baseline still rebuilds the child context.
Mark copied history as inherited, complete unfinished tool calls in the fork snapshot, and exclude inherited manual approvals from authorization review while retaining them in model context.
## Testing
Add coverage for preserved request prefixes, child instructions, legacy and paginated histories, Code Mode, missing inherited tool outputs, compaction fallback, and approval isolation across checkpoint replay. Update the noisy helper failure test to read its response before starting cleanup.
GitOrigin-RevId: ce9235dfa111c88d6ce66cb93d564fb63b326489
## What changed
Enable `instant_interrupt` by default so new user input can preempt responses and yield foreground code-mode observations. Keep the feature marked as under development and update feature-policy tests to allow this exception.
Explicitly disable instant interrupts in core, TUI, and Python SDK tests that depend on responses completing before steering or processing subsequent input.
GitOrigin-RevId: a8cab2d6c445bfdbd10b0b2abcf7893d32ee8595
## Why
Transcript content can contain forged role headers, transcript boundaries, or claims of user approval. Guardian needs to distinguish that content from host-assigned authorship metadata.
## What changed
- Add `features.guardianv2.transcript_mode` with `line` (the default) and `json` options for synchronous review and asynchronous scoring.
- Render JSON transcript entries with host-assigned metadata and escaped `text`, and prepend matching provenance instructions to reviewer and classifier prompts.
- Preserve JSON metadata when budget recovery shortens historical text, and keep provenance instructions outside the configured classifier prompt limit.
## Testing
Add coverage for forged roles and approvals remaining within their original entries, JSON metadata surviving budget recovery, and provenance instructions surviving prompt limits. Extend review and scoring integration tests to verify JSON evidence and matching instructions.
GitOrigin-RevId: 81a3580390d3c4d1a664e554976cda5f1adc9a2c
## What changed
- Add `features.guardianv2.async_classifier_mode` with `snapshot` and `conversation` modes. Local configuration overrides model defaults; snapshots remain the fallback.
- Retain completed classifier requests and responses in conversation mode, appending transcript deltas without repeating previously delivered user instructions.
- Rebuild retained history when authorization, classifier instructions, or parent compaction changes, after an incomplete response, or when the next request exceeds the configured token limit. Add `async_classifier_conversation_token_limit`, defaulting to 100,000 tokens, while preserving the model's input limit for fresh requests.
- Serialize conversation requests in observation order, bound outstanding work, and reject stale work after authorization changes or thread shutdown. Record retained and new input token costs.
## Testing
Add tests for configuration precedence, history reuse and resets, ordered admission, queue overflow, and stale or stopped requests. Exercise the approval matrix in both modes, including resume, fork, mandatory review, authorization changes, and stream failure after an early score.
GitOrigin-RevId: 35b9800104648cde4f467086e678dee12458c3e5
## What changed
Add `features.multi_agent_v2.message_board_remote` with a board URL and a bearer token supplied directly or through an environment variable. When configured, use the remote board in preference to local or in-memory storage, including in ephemeral sessions, while preserving the existing board tools and session identity.
Ignore remote board settings in project-local configuration and use the runtime HTTP client and clock for remote requests.
## Testing
Add a mock-server integration test and snapshot covering an ephemeral session posting through the existing tool, with the expected bearer authentication, session identity, timestamp, and returned post.
GitOrigin-RevId: 263413d90a1ee4c0bdba8c1b08ba9f68bdd7a986
## Why
Ephemeral sessions cannot use the SQLite-backed agent message board. An in-memory backend lets agents share discussions without creating durable board storage.
## What changed
- Add the opt-in `message_board_in_memory` setting to the multi-agent v2 configuration, allowing the board to run in ephemeral sessions when both required features are enabled.
- Share board state across agents in the same tree and release it when the last handle is dropped.
- Implement channels, posts, subscriptions, notifications, search, and paginated reads through the existing `AgentMessageBoard` interface, including request deduplication.
## Testing
Add coverage for shared handles, concurrent request deduplication, tree isolation, and state release. Run existing query and tool test cases against both backends, and extend the parent/child scenario to verify ephemeral board sharing without creating a board database.
GitOrigin-RevId: d0b2083f8ea5b1c5a3a70f258ef738b87ea74cef
## What changed
Remove the session-level capture mode and make thread-owned retained context the default throughout history management. Simplify input ordering, compaction identity preservation, fork handling, and approval freshness checks by removing legacy capture branches.
Keep checkpoint compatibility review separate: unknown or incompatible checkpoints can still use legacy review while retaining user evidence. Set the already-removed `guardianv2.thread_context` feature's default to false and remove redundant opt-out test variants.
## Testing
Update checkpoint tests to exercise legacy review through restored checkpoint data. Adapt existing compaction, resume, rollback, and fork tests to use unconditional context capture.
GitOrigin-RevId: ab23a0d7aca71d5a103458cff8b0c68137dd9708
## What changed
- Deprecate and ignore `features.guardianv2.thread_context`, including profile overrides, with a migration notice. Ignore managed requirements for the removed flag with a warning.
- Preserve surviving legacy root instructions across compaction and resume when retained instructions are incomplete. Include unmatched instructions in worker authorization context with an explicit unknown-ordering notice, without replacing newer retained facts or expanding the reviewer's model window.
- Use surviving source calls to roll back verified answers from older checkpoints that lack acceptance-order metadata.
## Testing
Add regression coverage for legacy instruction recovery, compaction and resume, source matching, and answer rollback around same-turn user input. Update configuration and Guardian review tests to verify that the deprecated opt-out still uses thread-owned context and rejects incompatible compaction evidence.
GitOrigin-RevId: a65936c9e0b912e7667d1385a2ec53df726565de
## What changed
Add `features.multi_agent_v2.disable_direct_message`, defaulting to `false`. When enabled, omit `send_message` and `followup_task` while preserving spawning, automatic child results, and the remaining agent management tools.
Require an available message-board `post` tool when this option is enabled for sessions using multi-agent v2 collaboration tools, exempting internal worker sessions.
## Testing
Extend configuration parsing tests and run the message-board subscription/resume scenario with direct messaging both enabled and disabled. Verify post search, subscription behavior, and which collaboration tools are exposed.
GitOrigin-RevId: 72ec22ef0b92fa81e02cdeb058d8b4f93aca3be6
## What changed
Mark `guardianv2.thread_context` as stable and enable it by default for synchronous and asynchronous Guardian reviews. Keep it independent of the Guardian v2 `enabled` toggle and preserve explicit configuration and profile overrides. Update the configuration schema documentation to match.
## Testing
Update coverage for default configuration and sender user messages, review prompt snapshots, history retention across compaction, and checkpoint provenance. Assert that later user input invalidates an in-flight review's authorization. Keep legacy transcript budgeting coverage by explicitly disabling thread context in that test.
GitOrigin-RevId: 19afd34d7bfc0ee36bbf878089c68b732a21bc6a
## What changed
Use `tui.fullscreen_transcript` to opt into the fullscreen transcript, including scrolling, selection, and search. It defaults to `false`; `--no-alt-screen` and `tui.alternate_screen = "never"` still take precedence.
The new preference controls both the first frame and application startup. Boolean CLI overrides for it are allowed during daemon startup. The old `features.transcript_v2` flag is deprecated and ignored, with a notice directing users to the new setting; it does not migrate into or override the preference.
## Testing
Add coverage for default terminal scrollback, fullscreen persistence through startup, alternate-screen restrictions, daemon override validation, and independence from the deprecated flag. Update existing history and activity tests to use the new preference.
GitOrigin-RevId: 4117bf1ee548fa8d101a594f9506673d87c74c15
## What changed
- Accept and ignore `features.personality` in user configuration, profiles, and managed requirements.
- Remove feature gating from `personality = "none"`, which strips the literal `# Personality` section when preparing model catalog instructions. Preserve explicit base instructions and existing thread instructions.
- Document deprecated personality fields in configuration, app-server schemas, and the Python SDK: `friendly` and `pragmatic` no longer select a style, and `supportsPersonality` is always `false`.
## Testing
Add regression coverage for ignored legacy flag values and managed requirements, personality opt-out behavior with the flag absent or set to either value, role overrides, and preservation of explicit base instructions, including empty strings.
GitOrigin-RevId: 4e12c66b42bfc59d6f151a5b3c28fadc6654ae99
## Why
Hosted Codex Apps shared the `mcp_2026_07_28` protocol setting with other MCP servers, preventing independent protocol selection.
## What changed
- Add `features.codex_apps_mcp_2026_07_28`, disabled by default, for the host-owned HTTP `codex_apps` server. Enabling it attempts 2026-07-28 discovery with Legacy fallback.
- Keep other servers, including third-party registrations with Apps-like names or URLs and local stdio servers, governed by `mcp_2026_07_28`.
- Support the new flag through `experimentalFeature/enablement/set` and refresh protocol settings in existing sessions. Track protocol mode per server when deciding whether to reuse connections.
## Testing
Add coverage for independent feature and protocol selection, hosted event-stream protocol selection, standalone Legacy defaults and discovery fallback, and runtime enablement refreshing an existing app-server thread.
GitOrigin-RevId: 640e8e251f0c45e5f4829cc2b73c3082cf42f715
## What changed
Replace `features.guardian_thread_context` with `features.guardianv2.thread_context` and update the configuration schema. The setting controls thread-owned context for synchronous and asynchronous Guardian, defaults to `false`, and remains independent of `features.guardianv2.enabled`.
## Testing
Update configuration tests to cover the nested setting, profile overrides, and enabling thread context while Guardian v2 is disabled. Migrate Guardian approval, history, and async scorer tests to the new configuration key.
GitOrigin-RevId: 54a91555eb68001e0adedc8a07bdbc5ea2273f9b
## What changed
- Add the disabled, under-development `guardian_thread_context` feature flag for selecting thread-owned context for Guardian reviewers.
- Expose the boolean setting in the generated configuration schema.
- Verify default, base configuration, and profile override resolution.
GitOrigin-RevId: c4878be96d12f4ccd84356df15d3e55f13ac141f
## What changed
- Add a stable `sleep_tool` feature that can enable or disable registration of the built-in sleep tool independently of the clock tool.
- Support structured `features.sleep_tool` configuration with `model_driven` and `always_on` modes. The default `model_driven` mode preserves the existing model and `current_time_reminder` behavior, while `always_on` registers sleep whenever the feature is enabled.
- Preserve nested sleep-tool configuration across CLI overrides, config merges, and feature toggles, and expose the settings in the generated config schema.
## Testing
- Cover feature-map overrides, both selection modes, legacy clock settings, config merging and editing, and invalid mode rejection.
GitOrigin-RevId: 18eadc582f8a4445958c29d063e5be495276703e
## What changed
- Add the `features.guardianv2.persist_scores` configuration option for debugging.
- Default the option to `false`, so Guardian V2 reviewed actions and risk scores are only written to rollout files when explicitly enabled and the session is not ephemeral.
## Testing
- Cover configuration deserialization, default non-persistence, and opt-in persistence for nested code-mode actions.
GitOrigin-RevId: 452af99ef14553d45140340ececc2913389124d0
## What changed
- Add the opt-in `features.guardianv2.free_guardian` setting to route eligible
Guardian reviews to `/guardian` and asynchronous classifications to
`/guardian-classifier`.
- Support endpoint selection for both HTTP and WebSocket Responses clients,
including endpoint-aware connection reuse.
- Keep `/responses` for API-key authentication, custom provider URLs,
non-Guardian models, and configurations where the option is disabled.
- Omit routing hints and `service_tier` from requests sent to the dedicated
Guardian endpoints.
## Testing
- Cover route selection across authentication modes, provider URLs, HTTP
fallback, WebSocket review sessions, and classifier sampling.
GitOrigin-RevId: 9c88673c710d009e0239559b9245a4e6c4f4befc
## What changed
- Add the under-development `transcript_v2` feature for the interactive
transcript composer and turn-selection UI.
- Keep it disabled by default and expose it through the configuration schema
and `codex features enable transcript_v2`.
## Testing
- Verify explicit configuration overrides and CLI persistence for the new
feature.
GitOrigin-RevId: 138ab7851621c066e8121cc3eb6cd4e7299f9c31
## What changed
- Add `features.guardianv2.review_scope.computer_use_only` to restrict asynchronous classification and fast approvals to browser and computer-use REPL tools.
- Keep other tools on the synchronous approval path without letting them age or reuse scores from in-scope calls.
- Give this scope precedence over `sandboxed_exec_commands` when both options are enabled.
## Testing
- Cover configuration precedence, direct and code-mode tool detection, fast-approval isolation, and end-to-end approval routing for browser, computer-use, and unrelated MCP servers.
GitOrigin-RevId: bfd9ab6abdbd90634b265d354e038724b1e81d65
## What changed
- Exclude sandboxed `exec_command` and `shell_command` calls from Guardian v2 classification by default while continuing to classify calls that request `require_escalated` permissions.
- Add `guardianv2.review_scope.sandboxed_exec_commands` to opt sandboxed shell commands back into classification.
- Keep other tools and namespaced shell tools in scope, and advance tool-call progress when a call is skipped.
## Testing
- Cover the default and configured review scopes, tool namespaces, permission modes, and skipped-call progress tracking.
GitOrigin-RevId: 32fb540c69959b9a82569f0f2fc76b5517496e6b
## What changed
- Add the opt-in `cwd_relative_turn_diffs` feature.
- When enabled, render turn diff paths relative to each selected environment's
working directory instead of the detected Git root.
- Preserve repository-root-relative paths when the feature is disabled.
## Testing
- Cover enabled and disabled behavior for nested working directories across
supported originators.
GitOrigin-RevId: 8b4908706a82b01f33ccd035b0945f9a29fce26f
## What changed
- Track the latest tool call and latest scored tool call for each Guardian v2 thread.
- Skip approval review when the score lags by more than `max_tool_call_lag` tool calls.
- Add `max_tool_call_lag` to the Guardian v2 configuration and schema, with a default of three.
## Testing
- Cover approval review at, above, and after recovering from the configured lag limit.
- Cover deserialization of `max_tool_call_lag`.
GitOrigin-RevId: fd870e143d95ee76491180e2aed742717248ff78
## What changed
- Add the `features.guardianv2.transcript.include_images` opt-in setting.
- Include recent images from user and assistant messages and configured tool outputs in Guardian v2 sampling requests.
- Bound image context to the four most recent images and 8 MiB total, and omit image detail hints when constructing the sampling request.
## Testing
- Cover configuration parsing and image forwarding from messages and tool outputs.
GitOrigin-RevId: b0ae6b6182535fd084ea103ed01dc3c803d7d1f7
## What changed
- Add `max_parent_compaction_tokens`, defaulting to 25,000 tokens, to the Guardian v2 feature configuration.
- Reuse the latest encrypted parent compaction only when its complete serialized item fits within the configured limit.
- Fail closed with the maximum action-risk score when the latest encrypted compaction is oversized, instead of sampling with older context.
## Testing
- Cover exact-boundary and oversized compaction items, including oversized passthrough metadata.
- Verify that an oversized latest compaction bypasses sampling and prevents approval.
GitOrigin-RevId: 0b308e7bec0f41d46433dfdf656948cee5cba667
## What changed
- Allow `features.guardianv2` to remain a boolean toggle or specify classifier instructions, the review threshold, reasoning effort, and action and instruction token limits.
- Add transcript controls for included sources, per-entry and total token budgets, and the number of recent non-user entries.
- Validate configured ranges and relationships, expose them in the generated config schema, and apply the resolved settings throughout Guardian v2 classification and approval review.
## Testing
- Cover boolean compatibility, configuration parsing and boundaries, config-manager rejection, and the resulting classifier request and approval decision.
GitOrigin-RevId: dc018b53b782e2d6b4d6a795cca4945130a71678
## 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
## 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
## What changed
Rename `features.tool_registry.include_tool_namespaces_info` to
`features.tool_registry.include_tool_metadata` across configuration parsing,
schema generation, resolved configuration locking, and tests. Update its
description to cover authoritative tool information in request metadata.
GitOrigin-RevId: 93b404483b71fed04031d767a41ac2bb70b836b2
## What changed
- Add `features.tool_registry.include_tool_namespaces_info` to the TOML model,
generated schema, and resolved runtime configuration. The setting defaults to
`false` and controls whether per-turn request metadata includes the resolved
tool namespace inventory.
- Preserve the resolved setting in session configuration locks.
- Cover top-level and profile-scoped strict configuration, deserialization,
resolution, and lock-file persistence.
GitOrigin-RevId: 74124086c0d7de30094b411001f0ec0af490935d
## What changed
- Track the first duplicate effective tool name while assembling the tool registry, including collisions introduced by external tools, code mode, and tool search.
- When `[features.tool_registry].error_on_tool_collisions` is enabled, fail the turn with a `duplicate tool: <namespace>.<name>` error before sending a model request.
- Continue allowing identical tool names in different namespaces, and preserve the existing collision behavior when strict checking is disabled.
## Testing
- Cover registry collision tracking, strict tool planning across tool sources, namespace isolation, failure before sampling, and pre-sampling compaction.
GitOrigin-RevId: 4cf83538fb513cec0b9c8b567780caaaadd3243d
## What changed
- Add `features.tool_registry.error_on_tool_collisions`, defaulting to `false`, to the TOML model, generated schema, and resolved runtime configuration.
- Treat `tool_registry` as structured configuration rather than a feature toggle, including in strict config validation and profile configuration.
- Preserve the resolved collision policy in session config lockfiles when it is enabled or explicitly configured.
## Testing
- Cover deserialization, strict validation, default and enabled resolution, feature materialization, and config lockfile serialization.
GitOrigin-RevId: 2c27109dcf2a3d1e51064cc60088703e36a0f85a
## What changed
- Add `features.multi_agent_v2.subagent_developer_instructions` to override inherited developer instructions for subagents that do not define role-specific instructions.
- Preserve role-specific instructions as the higher-precedence setting, and carry the effective instructions through full and bounded forks, compacted histories, and cold resume without duplication.
- Treat an unset override as inheritance and a blank override as clearing inherited instructions.
## Testing
- Cover configuration parsing and materialization, instruction precedence, fork modes, compaction, role application, and resumed subagents.
GitOrigin-RevId: 32321e61abc59b14a1be5f31e6bd6570bb1cd89d
## What changed
- Allow `features.code_mode_host` to use a configuration table with
`disable_in_process_fallback`. When enabled, failure to start the standalone
host is returned as tool output instead of falling back to embedded V8.
- Preserve the existing fallback behavior by default and continue accepting the
boolean feature toggle.
- Limit displayed host paths in spawn errors to 512 bytes while retaining the
executable-bearing suffix and valid UTF-8 boundaries.
## Testing
- Cover boolean and table-based feature configuration, fallback-disabled host
failures, and bounded ASCII and UTF-8 error paths.
GitOrigin-RevId: ab3d014e79054c2f8beef9a658915f01cca197b2
## What changed
- Accept a table form of `features.non_prefixed_mcp_tool_names` with an
optional `server_names` list while preserving the existing boolean form.
- Omit the legacy `mcp__` namespace prefix only for tools from selected MCP
servers. When no server list is provided, the enabled feature continues to
omit the prefix for every server.
- Cover configuration resolution, tool normalization, and an MCP stdio
round trip with selected servers.
GitOrigin-RevId: bdfb7ac54226de5051f06610e2c6b78b23912ef0
## What changed
- Add a default-on `features.multi_agent_v2.wait_agent_enabled` setting.
- Omit `collaboration.wait_agent` from the tool plan when the setting is disabled, independently of `features.current_time_reminder.sleep_tool`.
## Testing
- Cover configuration parsing and tool exposure with both clock sleep states.
GitOrigin-RevId: c2f34c5edd5bc191d6a5ac41d7bbb80708da1202
## What changed
- Assign IDs to client-created response items in every session, including streamed items, forked history, compaction results, and non-OpenAI provider requests.
- Preserve server-provided IDs and stable generated IDs across persisted and resumed conversations while continuing to omit unprefixed server IDs from outbound requests.
- Retire `features.item_ids` as a configurable feature. Existing configuration and CLI toggles remain accepted as compatibility no-ops.
## Testing
- Cover default ID assignment, persistence and resume behavior, remote compaction, provider requests, WebSocket requests, and removed-feature compatibility.
GitOrigin-RevId: 7a09e2d07d2606c2ef1e8e2283d36cb555557eae
## What changed
- Remove the `spawn_agents_on_csv` and `report_agent_job_result` tools and their agent-job runtime and state models.
- Drop the legacy `agent_jobs` and `agent_job_items` tables during state database migration.
- Keep `features.enable_fanout` and `agents.job_max_runtime_seconds` accepted as no-op compatibility settings while omitting them from the generated configuration schema.
## Testing
- Verify upgrades remove both legacy agent-job tables.
- Verify the removed feature and configuration keys still parse without taking effect.
GitOrigin-RevId: 8cc3337da78c67162229f02f40a747f503542646
## What changed
- Classify `multi_agent_v2` as stable while keeping it disabled by default.
- Exclude structured `multi_agent_v2` configuration from under-development feature warnings.
## Testing
- Update the warning-event test to verify that only the remaining under-development feature is reported.
GitOrigin-RevId: 12cb661dde9bc7b5aeae2f83476cb5ff75e0c959
## What changed
Remove tests that only restate feature registry metadata or constant values. Keep coverage for behavioral contracts such as feature aliases, dependency normalization, deprecated settings, and ignored removed settings.
GitOrigin-RevId: 45e2919dc3d854da3192ad7057a0f1c5c60271b9
## Why
Selected capability roots can contribute plugins, MCP servers, connectors, and
skills. Discovering each contribution separately requires repeated access to the
executor filesystem.
## What changed
- Add the `capabilityRoots/discoverV1` exec-server RPC to scan selected roots and
materialize recognized plugin manifests, configuration files, skill
instructions, and skill metadata in one bounded request.
- Add the opt-in `executor_capability_discovery` feature, with a thread-scoped
cache and per-step snapshot shared by MCP and skill discovery.
- Parse MCP, connector, and skill contributions from the materialized snapshot,
including serving cached skill instructions without another filesystem read.
## Testing
- Cover discovery limits, manifest precedence, root-local failures, cache reuse,
plugin contributions, and parity with the existing environment skill loader.
GitOrigin-RevId: f98fd2321cafb58c596db02da1f83c09d8eb375d
## What changed
- Add the `features.multi_agent_v2.expose_spawn_agent_model_overrides` setting, enabled by default, to expose `model` and `reasoning_effort` on the v2 `spawn_agent` tool.
- Keep these controls available when other spawn metadata is hidden, while allowing them to be disabled independently.
- Add root-agent and subagent guidance that overrides require a partial or context-free fork and should only be used when explicitly authorized.
## Testing
- Cover configuration parsing and defaults, usage-hint preservation, and tool-schema behavior with override exposure enabled and disabled.
