## What changed
Replace external `rg` scans and the fallback walker with an in-process `ignore` walker for bubblewrap deny-glob expansion. Remove scanner lookup and dependency tracking from sandbox integrity checks.
Include hidden and ignored files, respect scan depth limits, and fail closed on traversal errors. Anchor patterns to their static search roots and preserve literal leading `#`, leading `!`, trailing spaces, and unclosed character classes. Follow explicit symlink roots while skipping child symlinks, and mask canonical targets of matched paths.
## Testing
Extend unit and sandbox integration coverage for glob syntax, depth limits, traversal failures, symlink handling, commands launched from `/`, and operation without executing `rg`.
GitOrigin-RevId: 1767d7f37acb149457642bf24ee5971a28696438
## Why
Matches in parent directory names can crowd matching filenames out of limited search results. For example, searching for `ViewModel` should keep `ChatViewModel.kt` visible even when many directories are named `viewmodel`.
## What changed
- Rank basename matches before applying the result limit for single positive fuzzy queries without path separators.
- Prefer exact filenames, then the strongest exact directory match, then other matching filenames. Leave additional directory matches ranked by their paths.
- Compute highlight indices from the basename for promoted results and return scores that reflect the new ranking.
- Rank snapshots in resumable time slices so new queries and cancellation can interrupt the work.
## Testing
Add regression coverage for filename matches surviving the result limit, exact file and directory priority, path queries, and resuming partial rankings. Update app-server score expectations while preserving highlight indices.
GitOrigin-RevId: 41b3420581b4f6490859e809245370b737889544
## Why
A tool can start before an assistant message finishes streaming. The TUI needs to incorporate the completed text without duplicating the reply or leaving Markdown split across interrupted fragments. Some streams also include initial text in `item/started` before sending deltas.
## What changed
- Display initial assistant text from `item/started`, avoiding duplicate starts for the same message.
- Track interrupted replies by turn and item ID, then replace their flushed fragments with the completed message at the reply's original position, preserving intervening tool order.
- Re-render the completed Markdown and update transcript views and scrollback.
## Testing
Extend streaming tests to cover initial text, resumed deltas, Markdown spanning a tool interruption, and matching live and replayed transcripts. Expand completion-repair cases to cover missing text and resumed fragments.
GitOrigin-RevId: 7f35e52d0bca2100baf722d7ef4922cd127bbc45
## Why
Reasoning summaries can arrive with item start or completion events rather than streamed deltas. The TUI can miss or truncate these summaries, and replay after a voice handoff can hide reasoning that started before the handoff.
## What changed
- Initialize reasoning from item start payloads and reconcile live and replayed completions with their full summaries. Preserve streamed text when completion payloads are empty, and continue honoring `show_raw_agent_reasoning`.
- Retain active reasoning payloads across refreshes without resetting an already active item when its start event is replayed.
- Preserve the typed origin of reasoning started before a voice handoff and filter later delegated reasoning starts from buffered replay.
## Testing
Extend regression coverage for summaries supplied at start or completion, partial streamed summaries, active reasoning after refresh, and replay that retains pre-handoff summaries while hiding delegated reasoning even after the handoff marker is evicted.
GitOrigin-RevId: 724b9fc58e10f4d87dabd3d9930e252270855a4f
## What changed
- Map thread listing and creation, paginated turn and item history, and turn submission and interruption to Cloud operations.
- Mark listed and activated threads as using paginated history, and warn when history items cannot be displayed.
- Reject unsupported filters, custom settings, and structured input. Require stable submission IDs and avoid returning a running turn for duplicate or queued submissions.
- Forward optional `turn_trigger` values through the Cloud client.
## Testing
Add coverage for resume-picker pagination, unsupported filters, submission IDs and settings, duplicate and queued admissions, and `turn_trigger` wire encoding.
GitOrigin-RevId: dcbd87d8190786da65e343a3a0f8d849b24a5b26
Give each independent MCP server and session setup its own test identity
and timeout budget by replacing nested loops with `test_case::test_matrix`.
Preserve all 64 configuration combinations and the existing assertions for
direct tool exposure, tool search availability, and advertised tool calls.
GitOrigin-RevId: 74ef56d34b6bab3038b70d7d84183f7d104788a2
Move channel notification formatting into `PostPreview::notification_text()` and use it in the local message-board host. Preserve the notification fields, preview text, and `read_post` hint for truncated posts.
GitOrigin-RevId: fd3596c45194c958817a24f8fc35a886f766a84b
## What changed
Remove `summarize_sandbox_policy` and its public export from `codex-utils-sandbox-summary`, leaving `summarize_permission_profile` as the summary API. Migrate the external-sandbox, read-only, and workspace-write summary tests to permission profiles.
GitOrigin-RevId: 2ea039a2573e05c17edb8356aa7e04e065ef592a
## What changed
Add a `Housekeeper` that uses an isolated reviewer runtime to route captured original evidence into topic channels and update their discovery descriptions. Keep originals intact and batch inputs within the selected model's tool-output budget.
Validate routing responses before writing to the message board. Advance the evidence cursor only after all writes succeed, stop the worker after an error, and return the runtime disposition so callers can manage session reuse.
## Testing
Add integration coverage for routing originals to multiple channels, updating descriptions, preserving capture boundaries, batching within the input budget, and leaving the cursor unchanged on write failure.
GitOrigin-RevId: 670508c7ecf2ddffdd2946f1b25dd7e071318c5a
## Why
Evidence capture previously reloaded the full history without tracking consumer progress. Live consumers need to read new originals from activation onward and acknowledge them after downstream writes succeed.
## What changed
- Add an in-memory `EvidenceCursor` that starts at the current complete tail without backfilling, captures a fixed unread range, and supports partial acknowledgements. Reads leave progress unchanged.
- Add `ThreadStore::read_original_history` to read original records and their source positions through a fixed cutoff. Local storage supports append-only paginated root histories, including compressed rollouts, and defers unfinished records.
- Reject unsupported histories and invalid ranges, and retain source ordinals as evidence IDs.
## Testing
Add coverage for partial records, compressed suffixes, fixed cutoffs, mismatched thread positions, and truncation. Extend evidence tests to cover activation without backfill, partial acknowledgements, later appends, stale captures, and unchanged cursor progress after capture errors.
GitOrigin-RevId: c7a13749fedc4f44fadddc9dd9875043bccebd95
## What changed
Add `EvidenceSnapshot::capture` to read original evidence from `ThreadStore` into an immutable snapshot with root-history ordinals. Preserve accepted user messages, assistant messages, tool activity, verified answers, delivered assistant messages, and host-annotated approvals without changing their contents or provenance.
Exclude generated context and compaction output. Reject forked or reverted histories, inherited or ambiguously attributed user messages, and incomplete retained evidence. Capture currently supports append-only root histories and requires the host to flush pending originals first.
## Testing
Add an integration test covering content preservation, generated-context filtering, approval provenance, isolation from later appends, and rejection of ambiguous user messages.
GitOrigin-RevId: f464a2714c2678bcffe7abf0a8224196bfe48692
## What changed
When `features.guardian_denial_reconsideration` is enabled, retry the first terminal denial once using the unchanged inference request. Buffer provisional output so only the selected response enters reviewer history, while allowing tool calls to proceed normally.
Preserve the original denial if the retry fails or times out, and continue to honor cancellation. Account for token usage from both attempts, including failed reviews.
Remove `auto_review.experimental_denial_reconsideration_prompt` and warn when it remains in configuration.
## Testing
Update the Guardian scenario and snapshot to verify identical retry inputs, retained tool evidence, and reuse of the selected assessment in a subsequent review, with asynchronous compaction enabled.
GitOrigin-RevId: cc4e303d40a02acc824c8b4b954852325e64ad52
## Why
Guardian scoring and cached approvals need to use the requesting turn's captured policy even when the live thread configuration changes. Newly tightened mandatory review requirements must still prevent cached approvals.
## What changed
- Pass captured turn configuration through tool lifecycle and approval review inputs, and use it to resolve Guardian policy and classifier instructions.
- Apply current reviewer and model requirements before scoring and cached approval, including rechecking restrictions after collecting score authorization.
- Count computer-use JavaScript execution attempts even when background scoring is disabled, so a synchronous call consumes the initial-call allowance.
- Retain runtime configuration snapshots when applying agent role overrides, and share Guardian policy text resolution between configuration loading and runtime publication.
## Testing
Add and extend regression coverage for captured policy instructions, reviewer restrictions, stale cached evidence, and a synchronous computer-use call followed by an adaptive turn.
GitOrigin-RevId: 24ed4a1b6ce1733ad775790f30e440da614f9cd6
## Why
`pin-utils` 0.1.0 is unmaintained with no patched release and remains a transitive dependency through AWS Smithy and `loom` under `tokio-graceful`.
## What changed
Add `RUSTSEC-2026-0441` to the ignore lists in `codex-rs/.cargo/audit.toml` and `codex-rs/deny.toml`. Document the dependency paths and remove the exception when they drop `pin-utils`.
GitOrigin-RevId: 803d519ad3ad044d49d73ff2a172c6e0b01fc8d3
## Why
A Code Mode script can start a command without returning its session handle. Make retained sessions visible to the model so it can find running commands and collect exited results with `write_stdin`.
## What changed
- Add the disabled-by-default `command_sessions_world_state` feature.
- Publish snapshots of up to 16 retained sessions with their IDs, running or exited status, and whether they are in use. Report omitted sessions and suppress unchanged updates.
- Preserve session visibility when `write_stdin` is unavailable and refresh snapshots after compaction. Clear stale session handles after restart or when the feature is disabled.
## Testing
Add an end-to-end scenario and model-visible history snapshot covering a dropped command handle, unchanged state, unavailable polling, compaction, exit and result collection, and stale-handle cleanup after restart.
GitOrigin-RevId: 45704d8c6403149997231aafb8496c12879aff23
## What changed
Remove `dynamic_network_policy`, which only converted `SandboxPolicy` to `NetworkSandboxPolicy`. Update the Seatbelt network policy tests to call `dynamic_network_policy_for_network` directly with explicit `Restricted` or `Enabled` policies, preserving the existing assertions.
GitOrigin-RevId: 8d712cc542a07e516de677d69499aff7f3918354
## What changed
Allow experimental clients to request `deferOutput: {"commandExecution": true}` in `thread/items/list` for a specific `turnId`. Completed commands with a recorded completion time, exit code zero, and nonempty saved output return `outputDeferred: true` and `item.aggregatedOutput: null`. Clients can retrieve the complete output through `thread/items/read` using the turn and item IDs.
Keep full output by default and for listings across turns. Make conversion from `ThreadItemEntry` to `ThreadItem` fallible so Rust consumers detect deferred output instead of treating an incomplete item as complete.
## Testing
Add integration coverage for experimental capability gating, default and disabled options, command status and output eligibility, listings across turns, deferred-item conversion, and full output retrieval by item ID.
GitOrigin-RevId: d6bfac34bb68f7e3b327fd5553270ed6d0fe87cf
## What changed
Add the disabled-by-default `async_compaction_root_only` feature flag. When enabled, it restricts background compaction to root sessions, excluding non-root agents. Expose the flag in the configuration schema.
## Testing
Add a parameterized test covering root session eligibility and eligibility for review subagents and guardian sessions with the flag enabled and disabled.
GitOrigin-RevId: b4cce3f24f7f418ae61a82a7aef310f849cfd532
## What changed
Add configurable pane actions with default leader shortcuts:
- `leader z` zooms or restores the focused conversation pane.
- `leader ,`, `leader .`, and `leader =` minimize, maximize, or equalize pane widths within layout limits.
- `leader shift-h` and `leader shift-l` move the divider while the side pane has focus.
- `leader r` enters resize mode, highlighting the divider and showing keyboard hints. Arrow keys or `h`/`l` move it one column; Shift+Left/Right move it ten columns. Enter or Esc saves the width to `tui.sidebar_width_percent`.
Discard resize previews when terminal focus is lost or the split layout becomes unavailable. Preserve exact column widths at the current terminal size for presets and completed keyboard resizing, avoiding percentage-rounding drift.
## Testing
Extend TUI tests and snapshots to cover zoom and restore, width presets, divider movement, resize previews and persistence, and interrupted resizing. Extend keymap tests to cover zoom binding conflicts and custom chords.
GitOrigin-RevId: 7dd823fd8c2a0c90368c66f254c4fdd7c863c8a8
## Why
Shared hosts serve independent chats and their subagents. Larger callback workloads need room for unrelated work and control messages, while gRPC completion bursts can exhaust HTTP/2's small-DATA-frame budget and disconnect shared sessions.
## What changed
- Raise the active-cell limit from 128 to 2,048 and the pending delegate callback limit from 1,024 to 4,096. Expand request and transport queues to leave room for completion bursts and control traffic.
- Negotiate larger callback budgets through the stdio `delegate-capacity-4096` capability and gRPC `max_pending_delegate_calls` field. Preserve the 1,024-callback budget for legacy clients and enforce both session and shared host limits on gRPC.
- Limit concurrent gRPC completion RPCs to 64 across a provider's sessions, allowing queued completions to be canceled without waiting for delivery capacity.
## Testing
Add stdio and gRPC integration tests covering 256 cells and 4,096 callbacks across shared sessions while unrelated work completes. Add tests for callback budget isolation and reuse, rejection of zero capacity, and cancellation of queued completions. Include an ignored resource-intensive test for full host capacity.
GitOrigin-RevId: e85bfa24cc46cc8a735b464d80adf8066a6a6d3a
## Why
Pets were unavailable in tmux even when fullscreen Codex could render Kitty images through passthrough.
## What changed
- Enable pet images and picker previews in fullscreen tmux panes with Kitty passthrough, and update the unavailable notice to recommend fullscreen mode with `allow-passthrough all`.
- Use pane-specific image IDs and virtual placements for pets and previews, reserving separate IDs from transcript images. Repaint underlying text when pet placeholders move or disappear.
- Draw pets and previews when refreshing the fullscreen transcript, and consume preview areas once per render.
## Testing
Extend the owned-screen lifecycle test to verify that preparing fullscreen enables the Kitty protocol in tmux and returning to scrollback disables it. Update `/pets` notice assertions and the popup snapshot.
GitOrigin-RevId: 02c838ceb06abcbb45314e1d38ff4cde77221426
## What changed
Enable composer and transcript image previews in owned-screen mode under tmux when the client is Ghostty or Kitty, RGB is supported, and `allow-passthrough` is `all`.
Use Kitty virtual placements and Unicode placeholders so images move with their pane. Allocate image IDs per pane and repaint the viewport when replacing or removing images to clear stale placeholders.
## Testing
Extend image rendering tests to cover tmux virtual placements, placeholder snapshots, redraw retention, and overlay cleanup. Add probe coverage for pane-specific image IDs and rejection of visible-only passthrough.
GitOrigin-RevId: d34abacabfabc47a4354eab016ee4370835cadc9
## What changed
- Share the harness runtime identity with analytics delivery and turn-cost queries, and resolve request authentication together with its account-bound transport policy.
- Add runtime authentication to ChatGPT request helpers and `codex cloud`, including environment discovery. Resolve environment credentials for each request and honor CLI configuration overrides when loading cloud authentication.
- Preserve custom-backend authentication, validate runtime destinations, and keep cloud requests from following redirects.
- Forward only organization and project selectors from model-provider headers to API-key analytics requests.
## Testing
Add regression coverage for runtime request signing, credential refresh, account and resource selection, redirect credential handling, custom destinations, and cloud credential-store overrides.
GitOrigin-RevId: 75f33961ee6482881e9ff9817e99d977f31b65b8
## What changed
- Add `--chatgpt-token-stdin` for remote HTTPS registration and optional `--chatgpt-account-id`, which must match the token's account claim when present. Read a bounded, newline-terminated token from a pipe without persisting it to `auth.json`.
- Load managed configuration using the supplied account, enforce account restrictions, and preserve configured policy-server authentication. Skip ChatGPT policy lookup only for known plans that do not require managed configuration.
- Allow `--exit-on-stdin-close` to cancel pending policy loading, and redact the registration bearer from registry diagnostics.
- Reject incompatible stdin credential options, including flags placed on opposite sides of `forward`, and disallow ChatGPT token stdin authentication with `forward`.
## Testing
Add coverage for account-claim validation, policy selection, policy-server sign-in requirements, shutdown during policy loading, credential flag conflicts, and bearer redaction.
GitOrigin-RevId: b6b50565e1f150b96edf3cee796909a991f1b47f
## What changed
- Use the shared runtime and effective configuration for account API clients and remote plugin requests, including standalone plugin commands.
- Support dual-header and assertion-only authentication for remote plugins and MCP file uploads when runtime agent instances are enabled.
- Keep plugin credentials and caches scoped to the thread's account when resuming with different credentials. Bind request pools and multi-step plugin storage operations to the selected account so account replacement revokes stale operations.
- Protect runtime credentials on cross-origin redirects while preserving configured routing policies and legacy authentication for custom backends.
- Apply server-provided `upload_headers` to file storage uploads.
## Testing
Add coverage for shared runtime registration, both authentication modes, configuration reloads, resumed-thread account selection, account replacement during plugin uploads and downloads, and credential stripping on redirects. Extend file upload tests to verify runtime assertions and storage-only upload headers.
GitOrigin-RevId: 68aef81051a6f9bf919fffda52f372b108fce805
Replace loopback TCP sockets with an in-memory duplex connection in
`malformed_handshakes_preserve_active_streams_and_admission_recovers`
so Tokio can advance deadlines after both peers become idle.
Service keepalive pings while waiting for the handshake failure cooldown,
and remove the blocking clock guard and switches to real time for validation
timeouts and connection shutdown.
GitOrigin-RevId: 5c468ee9f150f701a819936322430e23ef3046a7
## What changed
Add a Model providers entry under Sessions to browse the connected app server's provider catalog. Show the current chat's provider and the default for new chats, with scrollable details for endpoints, authentication settings, and provider-specific configuration. Browsing does not change the active provider.
Handle loading, dismissal, stale responses, disconnected servers, and unsupported server versions. Refresh an open provider list when the first chat attaches.
## Testing
Add tests and snapshots covering provider lists, scrollable details, initial chat attachment, nested views, stale results after dismissal and reopening, and unsupported server methods.
GitOrigin-RevId: 2deb4e286b2648d9f459e403361e5501db98ca96
## Why
Decimal IDs of up to three digits fit in a single token. Issuing shorter IDs first keeps identifiers compact in model context.
## What changed
Add `codex-utils-model-facing-id` with deterministic, seed-based ID generation. Each salt prefixes the displayed ID and derives a separate sequence from the session seed. The generator shuffles decimal pools, exhausting `000`–`999` before issuing six-digit suffixes, then expanding in groups of three digits.
Support serializable, versioned snapshots that resume at the next unissued ID, plus suffix-only formatting for protocols that supply their own prefix.
## Testing
Add integration tests for pool exhaustion, stable outputs across pool boundaries, serialization and restore, salt-based seed derivation, invalid snapshots, and wraparound after the last `u64` ordinal.
GitOrigin-RevId: 80ffbf861106980b731d34a61ca2b9448d3bbb0d
## What changed
- Support `canonical_matching=True` in `prefix_rule` and `canonical_matching = true` in managed TOML prefix rules. Apply Unicode canonical caseless matching to every prefix token, including alternatives, while keeping exact matching as the default.
- Match case and canonically equivalent Unicode spellings, such as `bash` and `bAſh`, without resolving executables on the filesystem.
- Preserve managed restrictions when checking absolute-path rule amendments, and enforce applicable `host_executable` path allowlists during basename fallback.
## Testing
Add coverage for case folding, Unicode normalization, token alternatives, exact-match defaults, and host executable allowlists. Extend managed-policy and shell-execution tests to cover canonical matching.
GitOrigin-RevId: c2f79069dc38d55c77028c457b22beb468d5c571
## What changed
- Expose `AgentSessionReader` and `AgentRef` for read-only access to host-owned agent session membership.
- Read direct children when rendering V2 environment context, using the existing roster size limits. Refresh membership when rebuilding context after compaction, and omit the roster if the provider is absent or the read fails.
- Preserve unrecorded initial input across suspension or interruption while waiting for a roster read. Resolve the roster before advancing the compaction window.
## Testing
Add coverage for roster refreshes after compaction, unchanged environments avoiding extra reads, unavailable rosters, recoverable input during blocked reads, and stale compaction results rejected after a concurrent history replacement.
GitOrigin-RevId: 3c7e3822af09e9295d405e53dabb87b020c8f00c
## What changed
Add optional executor workspace roots to `SandboxTransformRequest` and resolve symbolic workspace rules after merging additional permissions. Preserve explicit deny rules and treat an empty root list as granting no workspace access.
Route Windows restricted-token preparation through the shared transform path and use explicit roots when building its direct-spawn wrapper. Update Windows MXC debug launches to bind configured roots before adding the managed CA read grant.
## Testing
Extend sandbox manager tests to cover workspace and subpath expansion, empty root lists, deny preservation, and the roots and write permissions serialized into the Windows wrapper.
GitOrigin-RevId: 0bebdb08b67cbbc182c18b031b9d13a21a799682
## What changed
- Allow dragging the pane divider and save the preferred width in `tui.sidebar_width_percent`, defaulting to one third of the terminal. Defer reflow until release when retained images are present.
- Support scrolling and loading older history in the unfocused pane, opening links, copying selections, and clicking its composer to switch focus while preserving the clicked text position.
- Keep assistant replies, running command completion, and turn status current in the unfocused pane without duplicating answers or completion metadata when focus returns.
## Testing
Add regression coverage for divider previews and saved widths, image-aware resizing, composer clicks, unfocused history pagination and copying, and streaming replies and command completion across focus changes.
GitOrigin-RevId: a26accc0f8df3c17f53bc915db29a11c8de3c480
## Why
The cloud backend discarded item start and completion events, preventing clients from receiving user message receipts and complete assistant messages through those notifications.
## What changed
Convert cloud user and agent message summaries into `ItemStarted` and `ItemCompleted` notifications. Preserve user submission IDs and text, assistant text and questions, and lifecycle timestamps. Continue ignoring unsupported item types.
## Testing
Add unit tests covering user receipt identity and text, plus completed assistant message text, questions, and timestamp.
GitOrigin-RevId: 3e88129553844a90eea2a006d35f32a0b7d9e53a
## Why
Saving local secrets invalidated the decrypted cache, forcing the next read to decrypt contents already available in memory.
## What changed
Populate the cache with the saved snapshot after the atomic write succeeds. Only cache the current schema version, leaving normalization and rejection of other versions to the read path. Reads continue to verify the ciphertext and keyring before reusing cached contents.
## Testing
Add coverage across all four local secrets namespaces for cache reuse after saving, including through backend clones, and preservation of the committed snapshot after a failed write. Update existing tests to verify cache reuse after setting and deleting secrets while retaining concurrent cold-read coverage.
GitOrigin-RevId: 61519aadc16bbe8db8c5055b126885500716418a
## Why
UI tree limits previously applied during rendering, silently dropping content
beyond the budgets. Validate the whole JSON tree before rendering so oversized
inputs are rejected, including content outside the visible line.
## What changed
- Add a `UiTree` string parser that limits JSON to 64 KiB, nesting depth to 16,
non-null nodes to 256, and total string content to 16 KiB of UTF-8.
- Represent text as string leaves or `text` elements with children. Remove node
keys, `spacer`, and `divider` elements.
- Require an explicit `row` gap as a non-negative JavaScript-safe integer measured
in terminal columns. Bound rendered spacing by the viewport and skip empty
children when inserting gaps.
- Update footer content and built-in status lines to use the revised tree format.
## Testing
Add coverage for malformed elements and gaps, whole-tree size boundaries, URL
length limits, large-gap rendering, and bounded UTF-8 prefixes for directly
constructed text. Update hyperlink and footer clipping tests for the new format.
GitOrigin-RevId: 3c00881d3e7f2d79d11aa188f64f0725cd47ee68
## What changed
Replace parallel lookup sets and per-turn maps with a single arrival-ordered list of pending interactive requests. Centralize request matching for replay filtering and cleanup, deduplicate repeated requests, and resolve user input answers against the oldest pending question for the turn.
GitOrigin-RevId: c02115c289718a39359a6e6653d1dc7d588d2f90
## What changed
Add `Client::list_threads` with cursor pagination, page limits, sorting, and originator filtering for unarchived threads. Return thread snapshots, optional read states, and forward and backward cursors while preserving server order and duplicate entries.
Allow stored thread snapshots to contain empty session IDs and model providers while retaining nonempty requirements for activation. Preserve the original snapshot protobuf bytes.
## Testing
Add fixture tests for pagination requests, default query encoding, snapshot and read-state preservation, legacy empty metadata, invalid responses, and activation validation.
GitOrigin-RevId: 6492cb60573d13cc7b7d0aa583d1dab6bccafc4d
## What changed
- Extend server-owned fresh-start bootstrap to embedded connections, preserving explicit profile and launch overrides.
- Require `config/read` to succeed before starting a fresh thread, including on servers that do not support the method.
- Prefetch `model/list` alongside `hooks/list` and reuse the result during bootstrap.
## Testing
Extend startup coverage for managed model and reasoning-effort defaults across embedded, daemon, and remote connections. Verify startup failure shuts down all initial backends, and directory-trust startup requests the model catalog exactly once while `hooks/list` is outstanding.
GitOrigin-RevId: c96edfbc13c98203b7c2a809a87d225e05cf5f1b
## What changed
Accept an optional `_meta` object on `mcpServer/resource/read` and forward it to MCP `resources/read`, including reads bound to an originating tool call. Update the protocol schemas and generated TypeScript and Python types.
Reject caller metadata containing host-owned `threadId`, `x-codex-turn-metadata`, or `codex/connectionLease` keys. For `codex_apps`, also reserve `connector_id`, `link_id`, and `_codex_apps.resource_uri` to preserve app and account routing.
## Testing
Add integration coverage for metadata forwarding through stdio, hosted app reads with and without a thread, and origin-bound widget reads. Cover rejection of reserved keys and non-object metadata.
GitOrigin-RevId: 227ee0fb5fe15fa2ff2ec66d4d5ae16de8935a8c
## What changed
Configure managed memory consolidation agents with a `PermissionProfile` directly and explicitly bind both configuration and permission workspace roots to the memory directory. Keep network access disabled and exclude temporary directories from writable roots. Preserve disabled and externally managed parent permission profiles.
## Testing
Extend regression coverage to check that inherited workspace roots remain readable but are not writable, protected metadata stays read-only whether or not it exists, and incompatible permission constraints prevent agent configuration. Verify effective filesystem enforcement, network policy, and disabled approvals across parent permission profiles.
GitOrigin-RevId: b1ae115cade059da9e5fb83c218a1d89185b4a70
## Why
Changing the default model provider should not prevent users from resuming or continuing a thread that uses another configured provider.
## What changed
- Resolve cold resumes using the thread's saved provider and reject explicit attempts to switch it on resume.
- Use retained provider configuration for loaded threads without reloading the current default selection, while continuing to enforce managed provider policy.
- Preserve errors for missing provider definitions and policy conflicts.
## Testing
Update app-server and TUI coverage for resuming with a different default, recovering after restoring a missing provider definition, preserving drafts across resume retries, and continuing loaded threads with malformed system defaults.
GitOrigin-RevId: c5bf3b03cacde7349480c94c2f10bac827a0eb1f
Update `workspace_policy_change_rejects_pending_transient_auth_fallback` to

checking the fallback credentials.
GitOrigin-RevId: 09b7812f2f072389f9633de977e63edfa45186ed
## What changed
- Log `thread/items/list` request IDs, cursor kinds, page sizes, next-page availability, elapsed time, and success status.
- Log remote-control item-page response preparation and WebSocket write times, along with request and stream IDs, sequence IDs, frame counts, wire bytes, and success, interruption, or write-error outcomes. Collect these transport metrics only when debug logging is enabled.

## Why
An enabled legacy feature flag could prevent a project's `agents.enabled = true` from overriding a lower-priority legacy opt-out, leaving V1 agent tools unavailable.
## What changed
Only stop scanning configuration layers at an explicit legacy feature opt-out. Enabled flags now allow the scan to continue, so project opt-ins can override lower-priority opt-outs while same-layer and higher-priority opt-outs remain effective.
## Testing
Extend the model runtime selector regression test to cover enabled `features.collab` flags in project configuration and CLI overrides, and verify that explicit `false` values still disable V1 agent tools.

## What changed
Update `seed_gateway_auth` to seed either the keyring or file credential store according to the provider's configuration, using `GatewayAuthManager::credential_id()` to identify credentials.
Use file storage in the gateway model-cache reuse and login-required invalidation tests to keep keyring latency outside the behavior under test.

## What changed
Expose `cloud_backend::connect` to adapt an authenticated `codex-cloud-client` client to `AppServerClient`. Support account reads, resuming a conversation by ID with saved settings, reading its metadata, listing the loaded thread, and unsubscribing.
Forward turn lifecycle events and agent message deltas, and track thread status from attachment notifications. Keep the previous attachment when a replacement fails, report stream disconnections, and reject turns without an active attachment. Unsupported requests and approval replies return explicit errors.
## Testing
Add tests covering failed attachment replacement, turn admission after disconnect, and thread status tracking across notifications and reattachment.

## Why
A temporary external credential provider failure should not clear cached authentication or appear as a logout.
## What changed
Retain cached credentials after transient external auth failures when they still satisfy the current login and workspace restrictions. Advance the auth generation when the forced workspace policy changes so pending reloads cannot publish credentials validated against an outdated policy.
## Testing
Add regression tests for retaining credentials without auth change notifications during a transient failure, notifying watchers after recovery, rejecting credentials disallowed by a workspace policy change, and discarding a pending fallback validated before that change.
