## Why
Saved model selections can outlive their bundled catalog entries and still need migration guidance.
## What changed
- Remove `gpt-5.2` and `gpt-5.4-mini` from the bundled model catalog.
- Preserve migration from saved `gpt-5.4-mini` selections to `gpt-5.6-luna` when the old model is absent, while respecting catalog-provided migration metadata.
- Update tests and snapshots to use current models or explicit test fixtures, and remove the obsolete prompt fixture.
## Testing
Extend migration tests to cover catalog metadata precedence, saved selections, replacement model and reasoning-effort persistence, acknowledged prompts, and missing or hidden migration targets.
GitOrigin-RevId: 82beea504cc4a15699677c28a61ec0939af3069c
## Why
Switching models can send images from conversation history with `detail: original` to a model that does not support it.
## What changed
Normalize image details on request copies using the receiving model's capabilities. Downgrade `original` to `high` when unsupported, covering user messages and function and custom tool outputs. Preserve stored image details so switching back to a supporting model retains `original`, and continue stripping details for Responses Lite.
## Testing
Expand unit coverage across image detail values and model capabilities. Extend integration coverage for model switches within and between turns, text-only models, and resumed and forked threads, including assertions that persisted tool outputs remain unchanged.
GitOrigin-RevId: 2561651ea74f045e00f708ae53771a41dcd49c94
## Why
Switching providers or authentication could reuse a previous identity's model catalog, including its default service tier. An in-flight refresh could also overwrite a newer account's catalog after cache storage completed.
## What changed
- Require a matching provider and auth identity for disk and in-memory catalog reuse. Treat legacy entries without an identity as cache misses and fall back to bundled metadata when the in-memory identity no longer matches.
- Recheck identity after fetching and storing a catalog before publishing it.
- Renew cache freshness only when the client version, identity, and ETag match the stored entry.
- Update cache fixtures to include the configured provider and auth identity.
## Testing
Add regression coverage for provider and auth switches, credential rotation, legacy and mismatched cache entries, conditional TTL renewal, and an account switch during cache storage. Verify that API-key requests do not inherit a ChatGPT catalog's default `service_tier`, while explicit tier selection still works.
GitOrigin-RevId: e15d7ffff238d951d7a1c6a68381cbb479994146
## Why
Background and empty-input turns could lack a `root_turn_id`, and detached memory requests omitted turn identity entirely. Tasks without a root could also adopt one from coalesced mailbox input.
## What changed
- Set `root_turn_id` to the task's turn ID at task start unless an inherited or recovered root is already present.
- Stop assigning roots from mailbox input or steering an active turn.
- Give detached memory requests a fresh UUID for both `turn_id` and `root_turn_id`, included in turn headers and client metadata while still omitting session and thread identity.
## Testing
Extend assertions for background turns, empty input, goal continuations, manual compaction, and detached memory requests. Exercise mailbox coalescing with both independent and inherited roots to verify the task keeps its established root.
GitOrigin-RevId: ee0f2f1b43542a9f5884f694c1d94341b476779c
## Why
Clients need a per-thread Daybreak toggle that survives restarts and can be
restored on resume without changing the access program of an active or future
turn.
## What changed
- Add experimental `daybreakEnabled` support to `thread/metadata/update` and
expose the saved value on thread responses.
- Store the preference in SQLite, including for threads without a first turn,
and preserve it through reads, resumes, reconciliation, and restarts.
- Copy the preference when forking a thread while keeping subsequent updates
independent.
- Keep `daybreakEnabled` separate from the per-turn `cyberAccessProgram` field;
app-server does not derive one from the other.
## Testing
- Cover persistence across restarts, cold reads, reconciliation, and forks.
- Verify metadata updates do not alter the access program of active or later
turns.
GitOrigin-RevId: bcf987a9fcd7b0ac8a88b1c8f0df06b33ed8ad6e
## What changed
- Add the creation-time `originator` to app-server thread responses and `thread/started` notifications.
- Persist originators in thread metadata and preserve the first recorded value across list, read, resume, rollout, and SQLite paths.
- Add an `originators` allowlist to `thread/list` for hosted backends. The local app-server accepts omitted or empty values but rejects nonempty filters.
## Testing
- Cover originator persistence across server restarts and list, read, and resume requests.
- Verify local `thread/list` handling for nonempty, omitted, null, and empty originator filters.
- Heap-allocate large TUI dispatcher futures in affected tests to keep them within the Windows test-thread stack.
GitOrigin-RevId: 73ad6e61b8fdd2d93a22d1f971723a19ec7be3fc
## What changed
- Remove the per-thread `RealtimeConversation` feature check when starting a realtime session.
- Retain `features.realtime_conversation` as a removed compatibility setting that has no effect, even when set to `false`.
- Document the always-available behavior for `thread/realtime/start`.
## Testing
- Cover realtime startup on forked and cold-resumed threads with the legacy setting absent, disabled, or enabled.
GitOrigin-RevId: d9cd9aa3898d1c2efb9414a8f40c86be8951e210
## What changed
- Add `turn_trigger` and `codex_turn_source` to `codex_turn_event` analytics.
- Read the source from effective Responses metadata, preserving configured-over-client precedence and reflecting accepted steer metadata.
- Omit trigger and source values from analytics when they exceed the existing Responses metadata value limit.
## Testing
- Cover event serialization, turn lifecycle emission, configured and client source precedence, size limits, and source updates after steering.
GitOrigin-RevId: bbd45af4c6af52956d2394b722ea78e65e5b9bd7
## What changed
- Include the complete upstream `response.usage` object in
`ResponseUsageMetadata.metadata` while retaining the existing `amount` field.
- Expose the metadata through `rawResponse/completed` notifications and update
the generated JSON and TypeScript schemas.
## Testing
- Cover SSE, WebSocket, turn, and compaction completion paths.
GitOrigin-RevId: 6d79b1b4c92ac11abf43ec98f380b4868288a701
## What changed
- Cover the default, explicitly enabled, and explicitly disabled states of
`tools.update_plan.enabled`.
- Verify prompt tool lists remain consistent across requests, including when
custom base and developer instructions are configured.
- Explicitly enable `update_plan` in existing fixtures that depend on the tool.
GitOrigin-RevId: 3be279cb5195dfc5892c2c8ff6a1461fac879309
## What changed
- Add the disabled-by-default `omit_app_server_notification_media` feature.
- When enabled, remove inline image and audio content from `item/started`,
`item/completed`, and `rawResponseItem/completed` notifications, including
tool output and image-generation results.
- Keep the media in model input; the filter only changes app-server
notifications.
## Testing
- Verify that image content is absent from all three notification types while
the model request still receives it.
GitOrigin-RevId: 9a4434d18a3dac6d67c2e0c3723ff4595a9b3797
## What changed
- Add an optional `timeoutMs` parameter to `thread/shellCommand` and propagate it to user shell execution.
- Preserve the one-hour default when the parameter is omitted or `null`, allow longer deadlines, and treat `0` as an immediate timeout.
- Reject negative or otherwise invalid values before execution. Timing out an auxiliary shell command leaves its active turn running.
## Testing
- Cover default, extended, immediate, invalid, standalone, active-turn, and interruption behavior.
GitOrigin-RevId: d72f67793d9766b7383f28d30140270a4a76a495
## What changed
- Parse optional `usage_metadata.amount` values from Responses API completion events without converting their string representation.
- Propagate the metadata through SSE and WebSocket streams, regular turns, and remote compaction.
- Add `usageMetadata` to the app-server `rawResponse/completed` notification and its generated schemas.
## Testing
- Cover missing, null, zero, and high-precision amounts, including completion events emitted during compaction.
GitOrigin-RevId: b16d81e8350eab0dc7ff613d0dc9dbed73041713
## What changed
- Add an optional `toolOutput` to `turn/start` for starting or steering a turn with a named function-call output instead of user input.
- Emit standalone outputs as `functionCallOutput` thread items, persist them in durable history, and include them in resumed threads.
- Validate that tool outputs have a name, are not combined with nonempty `input`, satisfy the text-size limit, and use supported image URLs.
## Testing
- Cover standalone tool-output notifications, model input, and resumed history in both legacy and paginated history modes.
- Cover the text-size limit for structured tool output.
GitOrigin-RevId: a1eeec7b9b7de67b1a1c5e829a54552b85ec118b
## Why
Linux managed networking routed proxy connections through filesystem-backed Unix sockets, requiring an extra readable sandbox path and stale socket cleanup.
## What changed
- Transfer loopback TCP listeners from the sandbox namespace to host bridge processes over anonymous Unix socket pairs.
- Validate transferred descriptors, keep bootstrap channels private to each sandbox launch, and close them before running untrusted commands.
- Tie proxy bridge lifetime to the sandbox so cancellation closes active upstream connections.
## Testing
- Cover descriptor validation and interrupted handoffs.
- Verify concurrent sandboxes keep proxy endpoints isolated and do not inherit privileged sockets.
- Exercise managed networking end to end through `app-server`, confirming proxied access succeeds while direct host access remains blocked.
GitOrigin-RevId: 6561e09c83b927c604951bf2aa00ff532d179da5
## What changed
- Add the experimental `turn/start.cyberAccessProgram` option with `standard`,
`daybreakBlue`, and `daybreakRed` values.
- Forward the selection as `access_programs.cyber` on Responses, WebSocket,
and remote-compaction requests made with ChatGPT authentication, while
omitting it for API-key and custom-provider requests.
- Preserve the per-turn selection across recovery, compaction, and child-agent
turns without making it a persistent thread setting.
## Testing
- Cover app-server forwarding, authentication boundaries, WebSocket reuse,
turn recovery, compaction, and child-agent inheritance.
GitOrigin-RevId: d2eb468f365b2214c5099bc21741cf30f8bd2eb5
## What changed
- Add an optional `turnTrigger` field to app-server `turn/start` requests and
expose it in the generated protocol schemas.
- Propagate non-empty trigger values to Responses request metadata as the
reserved `turn_trigger` field, while preserving the original value when a
request steers an active turn.
- Classify turns started by queue dispatch, goal continuation, retry recovery,
and realtime handoff.
## Testing
- Cover HTTP and WebSocket metadata forwarding, steering behavior, reserved
metadata handling, and the built-in trigger classifications.
GitOrigin-RevId: c12fe2c522286db21b76081ae6154fbf6bfb3639
## What changed
- Add the experimental `turn/settings/update` method for changing `model`,
`effort`, `summary`, and `serviceTier` on a specific live turn without
changing future turns.
- Report whether the update was applied or the target turn was unavailable,
and reject unsupported fields, disabled feature use, unsafe model changes,
and direct updates to parent-owned subagents.
- Document the method's feature requirements, null handling, and limits.
## Testing
- Cover current-turn and future-turn isolation, rejected and unavailable
targets, feature and capability gates, saved threads, and subagent ownership.
GitOrigin-RevId: 18440f6d7ee5fcd06ae23bd41b22c492b62bb2b5
## What changed
- Add `serviceTierForTurn` to `turn/start` so a newly started turn can override the service tier without changing the thread's saved tier.
- Treat `"default"` as standard speed and omitted or `null` values as inheriting the thread tier.
- Keep `serviceTier` authoritative for subsequent turns when both fields are supplied, and ignore the turn-scoped override when steering an active turn.
## Testing
- Extend the app-server turn-start test to verify both the one-turn `"default"` override and inheritance on the following turn.
GitOrigin-RevId: 4c2c4db21d8d31617a7a6e6df65bf54834e72383
## Why
Analytics need to associate subagent activity with the top-level turn that
caused it, while avoiding a stale association when steering makes that origin
ambiguous.
## What changed
- Add `root_turn_id` to turn and tool-item analytics events.
- Read the root from live turn metadata when each event is built, reporting
`null` when the root is unknown or ambiguous.
- Propagate the metadata through control-tool and code-mode completion facts so
correlated and background tool events retain the correct root.
## Testing
- Cover root IDs for top-level turns, subagent turns, correlated code-mode
calls, and tool events emitted after turn completion.
- Verify that queued and subsequent events report `null` after the live root is
invalidated.
GitOrigin-RevId: 42fd76541c3c716cec74787d47b50adb2d22e6d2
## Why
Parent-owned Multi-Agent V2 subagents must remain controlled by their parent,
but several app-server endpoints could still mutate them directly.
## What changed
- Centralize the direct-input ownership check and apply it to turn injection,
MCP calls, reviews, compaction, rollback and revert, shell and Guardian
actions, realtime requests, and goal mutations.
- Enforce the same policy for goal mutations on unloaded threads while keeping
goal reads and turn interruption available.
- Document the affected endpoint behavior and continue exposing
`canAcceptDirectInput: false` for parent-owned subagents.
## Testing
- Cover direct-input rejection for both legacy and paginated thread history.
- Cover goal mutation ownership checks for unloaded V2 subagents, V1
subagents, and non-subagent V2 threads.
GitOrigin-RevId: 791b7af98490aed5eab4e672b90661acad11ec23
## What changed
- Apply the existing direct-input restriction to `thread/settings/update` for
parent-owned Multi-Agent V2 subagents.
- Document the restriction and extend the direct-input test to verify that the
request returns an invalid-request error.
GitOrigin-RevId: 2eead01c6f54ec637c68573378f3b56a7ee85652
## What changed
- Remove the legacy `shell_command` handler and runtime, leaving `exec_command`
and `write_stdin` as the shell execution tools.
- Treat legacy `shell_command` model metadata as `unified_exec`, and normalize
legacy user opt-outs so they do not disable command execution. Managed feature
requirements and `shell_tool` can still disable it.
- Preserve shell approvals, sandboxing, zsh-fork support, and output truncation
through the unified execution path.
## Testing
- Cover legacy configuration and model-metadata compatibility.
- Exercise unified shell execution, approvals, truncation, and `apply_patch`
serialization across the app-server and core test suites.
GitOrigin-RevId: 5c2fd6164fc3519cdae4944cb9db276b8467311c
## What changed
- Emit started and completed collaboration tool events for multi-agent v2
`spawn_agent` calls, including failed invocations.
- Record execution duration and successful child-agent configuration metadata
without including the spawn prompt.
- Deduplicate collaboration and subagent activity items by call ID when
calculating per-turn subagent tool counts.
## Testing
- Extend the app-server multi-agent v2 integration test to cover successful
and failed spawn telemetry, duration, prompt omission, and turn counts.
GitOrigin-RevId: c1c2fb9cc2a1a9b0f63ef68509ad36d11a92d1e5
## Why
Project instructions must respect the selected environment's filesystem read
permissions. Tightening those permissions for a later turn must not allow
previously cached instructions to reach the model.
## What changed
- Apply each environment's filesystem sandbox while discovering and reading
`AGENTS.md` files.
- Fail thread or turn setup when sandboxing blocks a discovered instruction
file, while allowing a restricted project with no instructions to start.
- Clear cached instructions before refresh and include the Windows sandbox
level in the cache key.
- Ignore inaccessible ancestor marker probes so readable instructions in the
selected working directory can still load.
## Testing
Added coverage for restricted projects, denied instruction files, cache
invalidation after permissions tighten, and unreadable ancestor markers.
GitOrigin-RevId: 6ea1a27b9c873a6260e4f87d42ae1317a6a4ae4b
## What changed
- Remove `untrusted` from the CLI, configuration schema, and MCP tool interface. Explicit `approval_policy = "untrusted"` settings now fail with an actionable error.
- Remove the known-safe command allowlist. Projects marked untrusted now request approval for every command unless an explicit exec policy rule allows it.
- Keep command parsing conservative by treating in-place `sed` forms as mutating and ignoring unrecognized commands when recording memory usage.
## Testing
- Cover rejection of the retired configuration value and approval requests for commands in untrusted projects.
GitOrigin-RevId: d6bf425edddfffbb325eee6acf383434af5fd33b
## What changed
- Emit `codex_control_tool_call_event` for built-in control tools such as
`request_user_input`, `update_plan`, `view_image`, and goal tools.
- Record correlation and timing metadata plus completed, failed, rejected, or
interrupted outcomes, and include these calls in turn-level tool counts.
- Keep tool arguments out of control-tool analytics events.
## Testing
- Extend the app-server turn profile test to cover successful and failed
control tools, event correlation, turn counts, and argument exclusion.
GitOrigin-RevId: c20f73dfb79654e31b4b5040eddb0e0d91cae10d
## Why
The model provider does not reliably identify which curated plugin catalog is
available. ChatGPT authentication can be used with a custom provider, while an
unauthenticated session should use the API-compatible catalog regardless of its
provider.
## What changed
- Select the ChatGPT curated catalog only for authentication modes that use the
Codex backend; use the API curated catalog for API-key and unauthenticated
sessions.
- Initialize standalone plugin managers with the current authentication mode
across CLI, app-server, MCP, and external-agent migration paths.
- Preserve authentication mode while detecting and importing migrated plugins.
## Testing
- Cover catalog and skill routing across ChatGPT, API-key, unauthenticated,
Bedrock, and custom-provider configurations.
- Verify authenticated plugin migration uses the ChatGPT curated marketplace.
GitOrigin-RevId: 660a339ee8891c33aad961078d3a979242a6a166
## What changed
- Add `TurnInputRequest` and typed submission results for atomically starting a turn, steering the active turn, or declining input with a specific reason.
- Expose `start_or_steer_turn`, `start_turn_if_idle`, and `steer_turn` on `CodexThread`, and migrate Core consumers to these APIs.
- Make app-server `turn/start` steer an active regular turn and return that turn's ID. Reject incompatible output schemas and non-steerable turns without applying settings or enqueueing input.
## Testing
- Cover concurrent start-or-steer submissions, accepted and rejected settings updates, output-schema compatibility, idle-start rejection, and app-server steering.
GitOrigin-RevId: dd9b5528d76ec650c019e97af420bc13190ea86a
## Why
Client-facing command execution items can include recognizable secrets in the
rendered command or parsed command actions.
## What changed
- Redact secrets in `commandExecution.command` and `commandActions` for live
items, completed items, and replayed thread history.
- Keep command approval requests backed by the original executable command and
parsed actions while using the redacted representation for display items.
- Document that execution item commands are redacted display values rather than
executable commands.
## Testing
- Cover redaction for command conversion, parsed search actions, legacy replay,
approval flows, completion notifications, and rejected commands.
GitOrigin-RevId: 2ad056f21882bf5166182ad1a4ff0bf6471d9c0e
## What changed
- Emit dynamic tool-call analytics for code mode `exec` and `wait` calls, including duration and terminal status.
- Associate code-mode cells and their nested tool calls with the originating and subsequent model response IDs.
- Buffer correlated tool events until the next response is known, while flushing pending events when turns, threads, or the analytics queue close.
## Testing
- Add reducer coverage for correlating `exec`, `wait`, and nested tool events across turns.
- Add an app-server test that verifies production analytics include the cell and response IDs for a code-mode `exec` call.
GitOrigin-RevId: 8b34ab59c1ad68ebbd57f9c8a05f19ab04df48a4
## What changed
- Record the effective detail setting and source and prepared dimensions for
successfully decoded images.
- Associate message images with their role and tool-output images with their
originating call ID.
- Include the collected image preparation metadata in the corresponding turn
analytics event.
## Testing
- Cover image resize metadata, tool-output attribution, turn aggregation, event
serialization, and app-server analytics output.
GitOrigin-RevId: dbfb5ba1ce7cb02dd93d9b579c5109817f16aef5
## What changed
- Load and cache the host skill provider catalog during world-state contribution.
- Render host skill listings from that catalog with Core-compatible budgeting, while preserving Core's full prompt injection for selected host skills.
- Reuse the cached host catalog for shadow selection, including when skill listings are disabled.
- Preserve an empty Core-compatible skills fragment when every entry exceeds the metadata budget, and make budget warnings independent of the configured percentage.
## Testing
- Cover provider-backed host listings, selected-skill prompt injection, shadow selection, disabled listings, oversized prompts, empty fragments, metrics, and warnings.
GitOrigin-RevId: b6b2d8ea14386356094cff5783d121d74657e9e3
## Why
The notification helper buffers unrelated server requests, so the session-scoped
file change approval test could overlook an unexpected second approval request.
## What changed
- Consume approval resolution and file change completion events directly and
verify their request, thread, turn, and item identities.
- Fail if the second patch requests approval after the first patch was accepted
for the session.
- Shut down the app server gracefully and assert that it exits successfully.
GitOrigin-RevId: 53a3f746940677043e097094862c28faf4db1a8d
## What changed
- Disable shell snapshot startup so the test stays focused on file change approval.
- Shut down the app server cleanly and assert that the turn makes exactly two Responses API requests.
GitOrigin-RevId: b19a67791d1bd371523e68ad6fae32d1dd426f2f
## What changed
- Enrich `thread/list` and `thread/search` results for loaded spawned threads with live status and `canAcceptDirectInput`.
- Report `true` for V1 agents that accept direct input and `false` for parent-owned V2 agents, while leaving the capability `null` when it is unavailable or inapplicable.
- Distinguish untracked threads from threads known to have shut down when resolving loaded status.
## Testing
- Cover list, search, ancestor-filtered list, and rejected V2 direct-input behavior.
GitOrigin-RevId: d5faf2fc379a236661ff9167391541473ce5c1eb
## What changed
- Add optional `plugin_id` and `script_path` fields to execution approval and guardian assessment events.
- Propagate validated plugin attribution through delegated approvals, guardian-reviewed command items, app-server notifications, thread history, and rollout traces.
- Preserve attribution on both started and completed command items, including declined commands.
## Testing
- Extend core, app-server, thread-history, and rollout-trace tests to cover plugin attribution propagation and serialization.
GitOrigin-RevId: 723684d010cab04142918d7a95e06ed95d008da1
## What changed
- Resolve shell and unified-exec commands against the trusted plugin roots loaded for each turn.
- Add optional `pluginId` and safe plugin-relative `scriptPath` fields to command execution items and legacy execution events, and propagate them through app-server notifications.
- Include the attribution in command execution analytics while rejecting absolute, unsafe, and unattributed script paths.
## Testing
- Cover attribution for cached curated and remote plugin scripts from command execution through core and app-server events.
- Verify analytics serialization and unsafe-path filtering.
GitOrigin-RevId: 02fac3a233284ccfc6642fa502a95f1881dba83d
## What changed
- Add typed helpers for initialized app-server instances, JSON-RPC requests,
responses, notifications, and thread startup.
- Add a composable `MockResponsesConfig` builder while preserving the existing
mock config writers.
- Migrate the app-server integration suite to the shared helpers, removing
repeated request ID management, deserialization, initialization, and config
assembly.
## Testing
- Add unit coverage for composing mock provider, feature, and extra config, and
for compatibility of the existing mock config writer.
GitOrigin-RevId: 62da177c1d6e8299400de64bd6766567bf1ba3d8
## Why
Streamed message deltas can be dropped when the transport is saturated, leaving
clients with a truncated final response.
## What changed
- Include the last non-empty final agent message in successful `turn/completed`
notifications and mark the items as a summary.
- Treat completed message content as authoritative in the TUI, repairing an
incomplete stream while avoiding duplicate messages when `item/completed` was
already received.
- Continue backfilling full turn items for persisted `codex exec` threads when a
completion contains only the summary view.
## Testing
Added coverage for completion summaries, dropped stream deltas, duplicate item
handling, and directive-only responses.
GitOrigin-RevId: ffe9d36d683d6b6690e4a468ff68aa9189fe6ab7
## Why
Permission profiles defined by `requirements.toml` can be selected as active,
but their network configuration was not included when resolving the network
proxy specification for that selection.
## What changed
Merge managed permission profiles from `requirements.toml` with configured
profiles before looking up the active profile's network proxy settings.
## Testing
- Verify config loading retains the proxy settings of an active managed
profile.
- Verify `turn/start` accepts a managed profile with network settings.
GitOrigin-RevId: 3374f82a8fb0ce8f338fa2cea77c28ea2eb89636
## What changed
- Change `ReviewDecision::Denied` to carry a rejection string and update the generated protocol schemas.
- Preserve specific rejection reasons through command, patch, network, MCP, delegated, and automatic approval flows so tool results can return them to the model.
- Distinguish invalid approval responses from user declines and truncate oversized rejection messages before adding them to model context.
## Testing
- Add coverage for denial serialization, invalid app-server approval responses, dropped automatic reviews, network rejection propagation, and rejection-message truncation.
GitOrigin-RevId: d48a55643aa03c7ecfa08a8e4b669913eec5464a
## What changed
Add `cacheWriteInputTokens` to the usage breakdown in the
`rawResponse/completed` JSON schema, defaulting it to zero. Update the
compaction and turn-start notification expectations for the expanded usage
breakdown.
GitOrigin-RevId: d9232b724d646b803c7f5a64c5daa311f77ad408
## Why
Clients that account for individual upstream Responses API calls need the exact
usage for each completion rather than accumulated or estimated thread usage.
## What changed
- Add the opt-in `rawResponse/completed` app-server notification with the
`threadId`, `turnId`, `responseId`, and upstream `usage` payload.
- Emit the transient event for normal turns and compaction requests when
`experimentalRawEvents` is enabled. The event is not persisted or replayed,
and `usage` is `null` when the upstream response omits it.
- Export the notification in the app-server schemas and document its behavior.
## Testing
- Cover exact token breakdowns for turn and compaction completions.
GitOrigin-RevId: 49040a060bf1784c1ff1dd62112efb4a778428c4
## Why
Multi-environment turns can run against different filesystems, so a single
thread-wide workspace-root list cannot accurately describe every selected
environment.
## What changed
- Add optional `runtimeWorkspaceRoots` to each app-server environment selection.
Omitted roots default to that environment's `cwd`, while an empty list selects
no roots.
- Carry environment-native roots through turn selection, model-visible context,
permission materialization, and tool sandboxing.
- Keep the top-level `runtimeWorkspaceRoots` field as a compatibility input when
constructing default environment selections; explicit selections use their
own roots.
## Testing
- Cover thread and turn API defaults, overrides, empty roots, and schema
round-tripping.
- Verify foreign roots remain model-visible and remote execution applies the
target environment's roots before sandbox selection.
GitOrigin-RevId: c6e7a62883c45c676c153055f46a55ee15a323a4
## What changed
- Stop the TUI and app server from inspecting existing sessions at startup to
set `personality = "pragmatic"` automatically.
- Remove the migration marker, helper APIs, and associated tests.
GitOrigin-RevId: 9e963bf113aff21651696bbc463f2749ac0f510a
## Why
We should be running as many integrations tests as possible against the
split cross-OS configuration.
