## What changed
Mark `code_mode_only_strict_3p_tools` as removed and stop overriding MCP/app and dynamic tool exposure settings. Code Mode Only now honors `omit_tools_from`, namespace exclusions, direct-only namespaces, and dynamic tool deferral settings without strict-mode exceptions.
## Testing
Update coverage for exposure settings, hidden and policy-denied tools, app access restrictions, and deferred MCP catalog refreshes that preserve the cached prefix while `exec` uses the current tools.
GitOrigin-RevId: 356ccd572f952b5a80ff9a0c31085330b9fe6e8b
## Why
Resolving an existing installation ID takes an exclusive file lock, unnecessarily serializing readers.
## What changed
Read `installation_id` under a shared lock. If its contents are missing or invalid, acquire an exclusive lock and reread the file before generating a UUID, so an ID initialized by another process is reused.
## Testing
Extend the existing UUID reuse test to verify that resolution completes while another shared lock is held on Unix and still restores file permissions to `0o644`.
GitOrigin-RevId: e787d775eddb4d05653d42e809816be9536a94a3
## Why
MCP permission profiles need the directory context used to interpret them. Prepared calls must retain that context alongside their captured permissions across runtime refreshes.
## What changed
- Store each server's permission source as thread permissions or a captured environment `FileSystemSandboxContext`.
- Capture environment working directories, home and temporary directories, and materialized workspace roots. Retain the host working directory for thread permissions.
- Expose the captured source through `PreparedMcpCall::permission_source()`, while keeping hosted Apps on thread permissions even when a local environment is attached.
## Testing
Extend binding tests to verify that prepared calls retain environment sandbox paths across refreshes and expose the host working directory for thread permissions. Update elicitation coverage to include hosted Apps with an attached local environment.
GitOrigin-RevId: 87e94605daece324786eebc07b62a507d35e5ced
## What changed
- Record connection attempts and durations as `codex.websocket.connect` and `codex.websocket.connect.duration_ms`, labeled with `success`, `reauth`, and the configured `product_sku` when present.
- Detect reauthentication by comparing the current auth revision with the last successful connection, preserving that revision across connection resets. Include `auth.reauth` in connection logs and traces.
- Populate session telemetry with the configured product SKU.
## Testing
Extend tests to check reauthentication labels after account switches, product SKU labels for restored sessions, and failed-handshake counts, durations, and labels.
GitOrigin-RevId: 53a38b4460ab9021058dfe2fe104d0441993b18a
## Why
A failed memory-mode update could leave other metadata changes applied. Failed observed metadata writes for paginated threads also need to remain pending so persistence can retry them.
## What changed
- Apply observed metadata, memory mode, and optional recency advancement in one SQLite upsert, preserving monotonic recency.
- Require successful SQLite writes for paginated thread metadata when a state runtime is configured, retaining failed writes for retry.
- Use SQLite busy-retry helpers for read-state writes and immediate transactions.
## Testing
Add regression tests that reject SQLite writes to verify pending metadata survives a failed persist and a rejected memory-mode update leaves existing metadata unchanged. Both tests verify a subsequent retry succeeds.
GitOrigin-RevId: 652bf6ebee0197976852aaf9f096b907697fd590
## Why
SQLx's SQLite migration lock is a no-op, allowing concurrent database openers to race between schema version checks and migration changes.
## What changed
Run schema checks and migrations in one transaction, retrying SQLite busy errors from a fresh snapshot. Databases with a current schema need only a read lock, including on NFS. Include the error cause chain when the app server reports SQLite initialization failures.
## Testing
Add regression tests for eight concurrent database openers applying each migration once and for reopening a current schema while another connection holds a writer reservation with NFS settings.
GitOrigin-RevId: 38004d58a5c637ac1b2be53d07fd9a4c8efec7ab
## What changed
Add `max_total_section_tokens` to `ElasticSectionLimits`, with a builder and accessor. Reject maximums below the section minimum during construction and deserialization. Default to no section maximum and omit the field from serialized output when unset.
Clarify how required evidence uses section minimums and optional evidence can use unused reservations up to section maximums.
GitOrigin-RevId: 850f8ff2795c6e9d2b0d16d3bb0db1c3720e2354
## What changed
- Add `resolve_for_enforcement` to collect filesystem grants, denials, glob patterns, and platform defaults with backend-specific path handling.
- Use the shared result in Linux bubblewrap and macOS Seatbelt policy generation, including Seatbelt scratch access and filesystem policy equivalence checks.
- Pass already-derived filesystem and network policies to Linux seccomp setup instead of converting the permission profile again.
## Testing
Extend the Seatbelt glob test to execute sandboxed commands and verify that relative deny patterns through a symlink block reads and writes while sibling files remain editable.
GitOrigin-RevId: 748603f6b5a6db739b198a0f93a899041612370a
## What changed
- With multi-backend support enabled, show the current host before the first submission and use `leader b` to cycle through available connections. Expose the shortcut as `tui.keymap.global.change_host`.
- Preserve the conversation name and composer draft, including cursor position, attachments, pending pastes, and literal versus shell-command interpretation of `!`.
- Save explicit host choices in user-only `tui.default_hosts`, scoped to the local project and user identity. Use the saved host for new conversations, falling back to the first available connection when it is unavailable.
- Prepare the destination and check directory trust before replacing the current conversation. Block switching during voice calls and active turns, and remove replaced blank conversations from the session overview.
## Testing
Add coverage for shortcut visibility and remapping, draft and name preservation, project/user preference isolation, unavailable-host fallback, destination trust and startup failures, and voice-call guards.
GitOrigin-RevId: def7b088951336bec8fe3962954fba9b861f91c6
## Why
Elastic entry caps can shorten review framing and authorization warnings along with supporting evidence. Those boundaries and warnings need to remain intact when evidence is truncated.
## What changed
- Preserve protected framing, host notices, and exact planned actions during elastic entry preparation.
- Carry protection metadata through root conversation, trusted answer, and `node_repl` evidence composition while allowing supporting text to be capped.
- Wrap sender evidence in protected boundaries and a warning that partial context does not transfer permission.
## Testing
Extend elastic-budget regression coverage to verify that exact action JSON, permission boundaries, and sender evidence warnings survive while supporting text is capped.
GitOrigin-RevId: 0b4bebb5a9da3611c92d8176cec99c504e8b7b7b
## What changed
Add an integration test that verifies environment connection events follow the active turn's environment selection:
- A deselected remote environment emits no connection events for that thread.
- Thread startup and reselecting an already connected environment do not replay connection events.
- A reconnected environment notifies threads that select it without duplicate connection events.
Reuse the remote exec-server initialization helper to exercise reconnection.
GitOrigin-RevId: 7e1e630af2e3f051b3367e7cfcb4a0acc0771edc
## What changed
Expose `InheritedSessionId` so a host can supply a root session ID through `ExtensionDataInit` when starting a fresh child thread. The child retains its distinct thread ID, and the inherited session ID is persisted in rollout metadata and restored on resume.
Reject inherited session IDs for resumed, forked, or native agent threads, and reject an inherited session ID that equals the child thread ID.
## Testing
Add an integration test covering distinct child identity, inherited session metadata, and restoration after shutdown and resume.
GitOrigin-RevId: e3462433f9d8a0bba24251ee2b6d5329557ddb31
## Why
Switching back to a running thread can lose the active turn's state after its `TurnStarted` notification falls out of the bounded replay buffer, breaking steering.
## What changed
Retain the evicted active turn and include it in replay snapshots when it is missing from the stored turns. Clear the retained turn when turns are replaced, the active turn completes, or the thread closes.
## Testing
Add a regression test that evicts the turn-start notification, restores the thread, and submits two steering messages while preserving a queued follow-up. A snapshot verifies the steering messages and queued input remain visible.
GitOrigin-RevId: a4302a2e0990b907207c229361cbcec68ebbbdc4
## Why
A completed environment hook can be held up by a queued output-read RPC when its executor is busy, delaying the hook's decision.
## What changed
- Race pushed process events against output polling so a complete, ordered event stream can deliver the hook's output and exit status immediately. Retain polling as a fallback when events are incomplete or unavailable.
- Include launch-parameter preparation in the hook's timeout budget.
## Testing
Extend the executor ownership test to hold the owner's RPC slot while a `PreToolUse` hook finishes. Cover both allowing and blocking commands, checking that the decision arrives before the slot is released and that only the owning executor receives the hook.
GitOrigin-RevId: bc80b99a2a32379e3c2eafefe6db66a6a20f4048
## What changed
- Add the disabled-by-default `tui_workspace` feature for the owned transcript view. At terminal widths of at least 100 columns, show the parent conversation beside its side conversation, with only the focused composer accepting input.
- Retain the inactive conversation's transcript, draft, and status, and restore reading and search state when switching focus.
- Keep drawing and input paused until history replay completes, while refreshing skills in the background.
## Testing
Add snapshots and regression tests for pane resizing and composer styling, retained streaming output, history search after replay, pending skills refreshes, and modal input protection.
GitOrigin-RevId: 68938f263353b0cd3a9e9562e06293bfc8251cc6
## Why
The keypress inspector could not display `ctrl-alt-c` or `ctrl-shift-c` because these keys bypassed the active view as if they were plain `Ctrl+C`.
## What changed
Require the modifier set to be exactly Control for the `Ctrl+C` exception when routing keys to active views. Keys with additional modifiers now reach the active view.
## Testing
Add regression coverage verifying that the inspector displays `ctrl-alt-c` and `ctrl-shift-c`, while plain `Ctrl+C` still closes it for either uppercase or lowercase `C`.
GitOrigin-RevId: cdad4dc73c096e6f07d1a951123db981c4837eac
## What changed
Once Responses requests fall back to HTTP after exhausting WebSocket retries or receiving HTTP 426, keep subsequent requests and turns on HTTP for the remainder of the session. Clear cached WebSocket state and remove background recovery probes, recovery trials, and their acknowledgement timeout.
## Testing
Update fallback tests to verify that a second turn stays on HTTP without additional WebSocket attempts. Adjust retry and `Retry-After` request-count assertions to exclude background probes.
GitOrigin-RevId: a4f6376604527c14db8d60f79bd21c3aaf289f70
## Why
Injected agent messages need to reach active sampling before stale tool calls execute, while messages queued around a final answer must wait for the next task without requesting another response.
## What changed
- Include injected `agent_message` items in mailbox preemption checks when the matching turn still accepts mail and `DeferMailboxPreemption` is disabled.
- Treat injected agent messages as queue-only mail so they do not reopen delivery after a final answer or force a follow-up response.
## Testing
Add a streaming scenario and context snapshot covering idle injection, active sampling preemption, deferred delivery around a final answer, and preservation of message payloads and ordering before the next task.
GitOrigin-RevId: 70f49cbe5074725c11e1fcb33eea05e0e92e17f7
## What changed
Add `BoardBackend` so the core adapter selects the configured backend and supplies a `MessageBoardHost`, while the extension opens MCP, connected, remote, in-memory, and local boards at thread startup.
Move remote credential handling, HTTP client construction, and backend installation into `codex-agent-message-board-extension`, preserving existing notification delivery semantics.
GitOrigin-RevId: 98fa5525f142596c6cc6b203198fd537546c01d5
## Why
Hosts need to apply subagent-style capability restrictions without changing a thread's session attribution, agent lineage, or permission profile.
## What changed
Add the public `RestrictRootCapabilities` marker to thread startup extension data. Capture the restriction once at startup and apply it alongside the restrictions native subagents already receive. Hosts must supply the marker again when cold-resuming a restricted thread.
Use the restriction to gate user-input and plugin-install requests, async user messaging, legacy MCP tool approvals, and Full Access MCP form input. Exclude inherited user messages from Guardian's retained authorization context for restricted threads, including after cold resume.
## Testing
Add coverage for host-restricted tool registration, MCP approval rejection, Full Access form-input handling, and inherited instruction authorization after cold resume. Update handler tests to exercise the shared restriction flag.
GitOrigin-RevId: 4d6d7102a20dc747431c7511a74a204c773e8420
## Why
Session recovery needs time for reconnecting and replaying process output, with server retention allowing for differences in when each side detects a disconnect.
## What changed
- Extend client recovery to 50 seconds, reserving the final 5 seconds for process replay, and retain detached sessions and RPC process output for 80 seconds.
- Bound recovery registry requests to 6 seconds and allow 20 seconds for Noise handshake and initialization.
- Abort pending transport tasks when a Noise handshake fails or is cancelled, closing the WebSocket.
- Record recovery timeout stages and retention expiration reasons.
## Testing
Add coverage for closing the WebSocket when a Noise handshake is cancelled and for timing out stalled recovery registry requests while leaving retries to session recovery.
GitOrigin-RevId: 1fe5e41805b7d1bf1aea636f192092d7ec0adcd3
## What changed
- Add critical path capture status and duration fields to `codex.turn_profile` traces.
- Emit capture counts for complete and incomplete profiles, and total and component duration histograms for complete profiles, tagged by product SKU and reasoning effort. Record metrics once per turn timing state and skip disabled captures.
- Extend critical path histogram boundaries up to two hours to cover long turns.
## Testing
Add coverage for duplicate reporting, disabled and incomplete captures, product SKU normalization, trace fields, component durations, and extended histogram boundaries.
GitOrigin-RevId: 5b1af9255f1c4a376b61c81eb68c7a74b01ae9ae
## Why
Host-owned runtimes skip controller rollout-budget accounting. Give hosts an optional callback to account for inference spending and signal budget exhaustion.
## What changed
- Add `AgentUsageAccounting`, `AgentUsageReport`, and `UsageAccountingDecision`, captured at startup and supported by host child spawn reservations.
- Await per-response usage reports with thread and turn attribution, including provider budget units and foreground and background compaction usage.
- Map host exhaustion to `SessionBudgetExceeded` and accounting failures to fatal errors without retrying inference. Preserve the original error for incomplete responses.
- Keep controller accounting unchanged and leave accounting disabled for host-owned runtimes without a provider.
## Testing
Add coverage for usage attribution, child accounting, budget exhaustion, nonretryable accounting failures, incomplete responses, and compaction reporting, including background usage charged once to its originating turn.
GitOrigin-RevId: 887703f50fe882497e4e8cb33259072935ec82e0
## Why
`codex exec --output-last-message` wrote through a pathname after tools finished, allowing sandbox activity to redirect the final write by replacing that path with a symlink. The related risk is described in https://github.com/openai/codex/pull/25956.
## What changed
- Open the destination before starting the agent and retain its handle until the final write.
- Reject symlinks, Windows reparse points, and multiply linked files; verify that the pathname still identifies the bound file before truncating and after writing.
- Propagate output errors so the command fails when the destination cannot be opened or written safely.
- Preserve inherited Unix output streams, FIFOs, devices, and Windows `NUL` support, while avoiding duplicate final answers when human output targets stdout.
## Testing
Add regression coverage for sandbox-created symlinks across consecutive invocations, redirected stdout, delayed truncation, hard links, replaced paths, and Windows stream binding and filesystem identity checks.
GitOrigin-RevId: 4a31bd28a5eb2d0a9e200cb658eb7d19dc93e933
## What changed
Enable `multi_agent_v2` and the new `agent_message_board_mcp` feature to automatically start a temporary, tree-scoped HTTP MCP message board without plugin or endpoint configuration. The MCP feature defaults off and takes precedence over `agent_message_board`.
Share board state across parent and child agents while retaining each caller's host binding. Keep the server alive while participating threads remain, and serialize board tool calls through the MCP server configuration.
## Testing
Extend the HTTP board integration scenario to cover automatic discovery, parent-child message sharing, child subscriptions and posts after the parent unloads, serialized mutations, and absence of a persistent board database.
GitOrigin-RevId: 613183c14b2ab67dfb1aaf3a3abf338376d1cc05
## Why
Pressing `Esc` in the memory reset confirmation could also close the memories settings popup instead of returning to it.
## What changed
Stop forwarding `Esc` to a view's key handler when its cancellation handler has already handled the event, even if the view remains open.
## Testing
Extend the memory reset confirmation test to verify that the first `Esc` returns to settings and the second closes the popup.
GitOrigin-RevId: b842fdaed69a1ac2a6af6fc454e02be2ac8946e6
## Why
Saving a generated title awaited thread metadata reads and name writes in the TUI event handler, delaying its return to keyboard polling.
## What changed
Move automatic title persistence into the background title-generation task. Make metadata reads cancellable and serialize automatic writes with manual renames so a manual name takes precedence, including when an automatic write is already in flight.
## Testing
Extend title tests to check that completion dispatch returns immediately, canceled metadata reads finish, and manual renames wait for in-flight automatic writes. Retain coverage for saving titles to the originating thread after switching threads and preserving existing names.
GitOrigin-RevId: b284a06ca3f0fdcf22fd2fc87b07447f8ab754c0
## What changed
- Skip rendered-row counting during history hydration when there is no row budget or no next item page.
- Return early when checking history insertion prefixes if there is no active cell or the placeholder session header must remain active.
GitOrigin-RevId: 669ebf0ceb0fc01c8a7bfd8d2addbcbb6fc6a364
## What changed
Add `AgentRuntimeOwnership::Host` and an `AgentTurnAdmission` provider so hosts can acquire execution capacity before runtime tasks run, including root turns. Require the provider at startup and retain its execution guard for the task lifetime. Controller ownership remains the default; host ownership skips controller rollout-budget accounting, budget reminders, and subagent roster context.
Keep pending admission interruptible without blocking input submission. Report admission failures through the turn lifecycle, record accepted input before exposing the error, and unwind task setup such as review mode. Preserve recoverable input during suspension. On interruption, skip prompts that still require a `UserPromptSubmit` hook rather than recording them without inspection.
## Testing
Add integration tests for missing-provider startup cleanup, denial and immediate retry, steering during admission, cancellation, execution guard lifetime, submit-hook handling, suspension recovery, and review-mode cleanup. Add a context snapshot verifying retained input reaches the next admitted turn.
GitOrigin-RevId: 9ee85fad2ecfbfb38735bac8ef88888fb179a967
## Why
Deduplicating against optional transcript entries can remove retained instructions or required tool calls even though the optional copies may later be evicted. Elastic instruction caps can also report evidence loss for revisions already delivered in full.
## What changed
- Capture the review's budget policy and use it for feasibility checks, admission, and restoration after compaction.
- Prefer required and protected native messages over optional duplicates, and use only complete, required pending transcript entries as proof of instruction delivery.
- Match elastic instruction duplicates by source revision and discard truncation observations for copies already delivered in full.
## Testing
Extend coverage for compaction recovery under fixed and elastic budgets, required and protected tool-call deduplication, and capped instruction duplicates covered by complete delivery metadata.
GitOrigin-RevId: fe456e645cdba6f782fb16ad582702d3b7ed012c
## What changed
- Consult SQLite before scanning for ancestor rollouts when no prefetched path is available. Validate that indexed paths resolve to managed storage and match the expected rollout ID and owner.
- Fall back to another copy when an indexed rollout is invalid, preserving the indexed copy's error if recovery fails.
- Skip ancestor cutoff validation when resolving history pages, which read projected rows and only need ancestor metadata for lineage bounds.
## Testing
Add regression coverage for indexed archived and compressed rollouts, invalid paths and owners, fallback recovery during context loading and forking, and history paging with an incomplete compressed ancestor.
GitOrigin-RevId: 486afdc8d49c829130b34d1544f325907c67628a
## Why
A fork's inherited history can become unreadable when the preferred ancestor rollout is truncated or has an incomplete compressed frame, even when a usable archived copy exists.
## What changed
- Retry failed ancestor reads using another copy of the same rollout, validating its owner and location before rebuilding the lineage.
- Apply fallback to model-context loading, fork and revert preparation, and paginated history reads. Preserve the original error when no usable replacement exists.
- Validate inherited byte offsets when opening ancestors for consumption, allowing a newer model-context checkpoint to avoid reading an unusable ancestor.
- Limit ancestor materialization to the inherited history boundary while preserving any existing progress beyond it.
## Testing
Add regression coverage for incomplete compressed ancestors, replacement ownership checks, archived-copy recovery during resume and fork, and materialization boundaries. Add an app-server test that cold-resumes a fork and pages inherited turns and items from an archived copy when the active ancestor is too short.
GitOrigin-RevId: 43730c17329ac759f7292b16ddf0d9eb463e3310
## Why
Automatic Git marketplace upgrades can repeatedly check out the same revision only to reject it because its manifest name differs from the configured marketplace name.
## What changed
Cache name mismatch rejections and reuse the error when the configured name, source hash, ref, sparse paths, and remote revision are unchanged. Store the cache outside the checkout without persisting the source URL.
Manual upgrades bypass the cache. Only cache rejections when the checked-out revision matches the queried remote revision and the manifest paths contain no symlinks, since symlink targets can change without a new commit.
## Testing
Add a regression test covering skipped repeat checkouts, manual retries, ref changes at the same revision, and successful recovery after a new revision restores the configured name.
GitOrigin-RevId: 586e6247a18a79563be168ff9da5b30573ecc497
## Why
Host-provided context such as budget reminders can become stale while compaction runs. Replaying a captured value or retaining its comparison snapshot can prevent the next step from emitting a fresh reminder, even when the remaining budget has changed.
## What changed
- Add `WorldStateSectionContribution::without_full_context()` to omit a section's fragment and comparison snapshot from initial and compacted context rebuilds while preserving ordinary step updates.
- Reset comparison state after prefix compaction for sections excluded at either capture or installation, including when their messages survive in the live suffix.
- Include step World State updates when building debug prompt input.
## Testing
Add regression coverage for budget reminders refreshing after remote compaction within the same threshold, unchanged request prefixes within a context window, refreshes with a retained live suffix, and step reminders in debug prompts.
GitOrigin-RevId: ea4456755e16c93b5d16e8c762b26a33f8571a86
## What changed
Register Guardian evidence-board cleanup with the app server's thread store when Guardian V3 is enabled. Leave Guardian storage untouched when the feature is disabled, and report cleanup failures as thread-store errors.
## Testing
Extend deletion tests to cover feature gating, preservation of unrelated boards and a surviving main thread's board, and corrupt-database recovery. Expand message-board tests to verify namespace isolation and persistent deletion markers that prevent later writes.
GitOrigin-RevId: d9119d22607769c92448d0f3cacbbfd03fbdf943
## What changed
Replace `thread_store_from_config` with `ThreadStoreBuilder`, exported through `codex_core` and `codex_core_api`, and migrate callers to the builder.
Allow hosts to register `with_additional_cleanup` for permanent deletion in local stores. The callback runs after successful agent-board cleanup and before rollout deletion, under the existing deletion locks. Document that cleanup must be idempotent and must avoid thread-store operations that reacquire those locks. In-memory stores do not invoke the callback.
Preserve the existing backend selection, startup rollout migration, and compression behavior.
GitOrigin-RevId: f2853d7de06fe12ef29451b204cf9fcbb349c359
## What changed
Add `RealtimeSidebandTransport` and `Op::RealtimeConversationAttachStream` so callers can attach Core to an existing realtime call through bounded JSON channels without opening or reconnecting a socket.
Read events independently of outbound backpressure, enforce a 1 MiB message limit, and drain accepted input on detach or channel closure before flushing the transcript. Pending writes are never replayed.
## Testing
Add transport and Core integration tests covering delegation without a callback socket, stalled output, attachment replacement and detach, channel closure, oversized messages, and preservation of queued transcripts in history.
GitOrigin-RevId: 06b7d1dfe2388054438d72d925e510a959dfe106
## Why
A transient WebSocket failure previously kept the session on HTTP for its remaining lifetime, even if WebSocket connectivity recovered.
## What changed
- Probe WebSocket connectivity in the background during HTTP fallback, allowing a subsequent request to use a ready connection without delaying HTTP requests.
- Verify recovery with a real request and bound its first-response wait to five seconds. Keep HTTP 426 responses and recovery timeouts on HTTP for the rest of the session.
- Keep retries of an HTTP request on HTTP. If a recovered connection fails before output, replay the request over HTTP without consuming its ordinary retry budget; failures after output use normal retry accounting.
- Rate-limit recovery probes and honor `Retry-After` deadlines.
## Testing
Extend integration coverage for successful recovery within a turn, disconnects before and after output, full-context replay followed by incremental WebSocket requests, persistent HTTP 426 fallback, and retry deadlines.
GitOrigin-RevId: 1c139a4bbce1a67442db5622fd70ff0cc8056c9c
## Why
Delegation messages containing `<source_orbit_id>` fail sender provenance parsing, leaving Guardian without the sender's instructions.
## What changed
Accept an optional `<source_orbit_id>` between `<source_thread_id>` and `<input>`, rejecting values containing `<`. Continue to derive sender authority from the source thread ID.
## Testing
Update the cross-host sender context scenario and snapshot to include orbit attribution. The scenario checks that sender evidence reaches Guardian after compaction and rollback without exposing it to the receiving agent.
GitOrigin-RevId: 463b18667384d30297245eedcd0f6bcbf683634e
## Why
After provider setup, new threads could still use the models manager created for the server's startup provider, leaving their default model inconsistent with the model picker.
## What changed
- Build a models manager from the thread's configuration when its provider differs from the startup provider.
- Invalidate the model catalog after successful Amazon Bedrock setup so subsequent model listings reflect the configured provider.
## Testing
Extend Bedrock and GCP setup integration tests to verify that a new thread's model matches the refreshed model listing. The Bedrock test also checks that the thread uses `amazon-bedrock`.
GitOrigin-RevId: 1db30ad040ba97e2f4f31c9e162a2b73af1377fa
## What changed
Eligible interactive launches now start or reuse the shared daemon regardless of `features.daemon_auto_start`. Remote-control daemon eligibility also no longer checks this flag. Use `--no-daemon` to run without the shared background server.
Treat `daemon_auto_start` as removed: ignore configured values with a migration notice, ignore managed requirements with a warning, and hide the flag from experimental feature discovery. Remove its launch telemetry tag.
## Testing
Extend retired-feature requirement coverage and add a migration-notice snapshot. Update CLI and TUI integration tests for daemon startup and explicit `--no-daemon` usage.
GitOrigin-RevId: e0290e5acd4bc0169a0f71c3296c567e46269ce3
## Why
The previous histogram placed post-truncation values just over 4,000 bytes in a bucket ending at 8,000 bytes, obscuring their size near the truncation cap.
## What changed
Use logarithmic boundaries through 4 MiB for `codex.additional_context.value_bytes`, with an explicit 4 KiB boundary near the truncation cap.
## Testing
Add a regression test verifying that post-truncation samples between 4,024 and 4,043 bytes land in buckets ending at or below 4 KiB while preserving their sum and count.
GitOrigin-RevId: af268fc0de3d5ceb648ce51fced3918317f2457a
## Why
`CodexThread::call_mcp_tool` returns only the tool result, so computing attribution and creating a cached runtime binding for these calls is unnecessary.
## What changed
Add `McpRuntime::latest_call_tool_without_attribution` and use it for direct thread calls. Validate the call, wait for server startup, and dispatch through the latest connections without capturing an attribution binding.
## Testing
Extend the runtime binding cache test to verify that a successful call without attribution leaves the cached binding empty. Update the test server to return a successful tool result.
GitOrigin-RevId: 898e655d9a0174ddaf71c390757d6fc9a5a61780
## What changed
Strengthen the execution cancellation test to verify that a session approval wakes a queued request before it is polled again. Assert that the request remains unwoken while the session policy commit lock is held, then receives a wakeup after the grant completes.
Wait for the second request to hold a prompt queue reference and install a counting waker on its semaphore. Share `WakeCount` with the existing manual prompt wakeup tests.
GitOrigin-RevId: c559a7c31385000347cd1c7dace25e84d1099db9
## What changed
Move inline tests for authentication, bearer auth, model endpoints, and providers into dedicated `*_tests.rs` files. Register workspace-routing tests under the `workspace_routing` module and keep test-only imports with the tests.
GitOrigin-RevId: 9ba043c82814e27be63432a0e13a4929dc3ea372
## What changed
- Thread `ContextBudgeting` through synchronous context and image preparation. Elastic mode preserves candidates for later entry capping and allocation; existing reviewer callers continue to use `Fixed`.
- Defer transcript selection, supporting-text caps, and image budget admission in elastic mode while preserving exact planned actions. Mark host framing as protected and distinguish optional user messages from required manual approvals.
- Add `ElasticBudgetConfig` validation requiring section minimums, including fallback policies, to sum to `DEFAULT_MAX_INPUT_TOKENS`.
## Testing
Extend tests for elastic transcript preservation, deferred native tool-call limits, oversized planned actions, image allocation, and section minimum totals above and below the required budget.

## Why
Connected legacy MCP sessions and HTTP keep-alive connections can retain message-board state after shutdown. Pending board bindings also need cancellation before they can dispatch a tool call.
## What changed
Explicitly close MCP sessions after HTTP drains and track binding factories and handlers until they release their state. Cancel pending bindings during shutdown while allowing already-dispatched board operations to finish. Clarify that `LocalServer::shutdown` waits for cleanup, while dropping the server initiates it.
## Testing
Add regression coverage for shutdown with a connected legacy client, a paused board binding, and an unauthenticated keep-alive connection. Assert that shutdown releases the board host before returning.
