## Why
Remote compaction already uses the normal Responses API, leaving the legacy `/responses/compact` runner unused.
## What changed
- Remove the legacy runner, endpoint client, request types, analytics variant, and obsolete test helpers and snapshots.
- Move tool-output trimming and its metadata tests into `compact_remote_history` for reuse by remote compaction v2.
- Consolidate retained-history filtering in the v2 implementation and remove redundant `RemoteCompactionV2` settings from tests.
## Testing
Extend the retained-history unit test to explicitly check that hook prompts survive compaction.
GitOrigin-RevId: 999bb1391aa22c3c281d6a96f98817d6c9e46ed9
## What changed
- Route manual and automatic remote compaction through the v2 implementation.
- Retire the `remote_compaction_v2` feature toggle while continuing to advertise it in the model client beta features header.
- Migrate compaction tests from `/responses/compact` to streamed `/responses` requests with `compaction_trigger` items and remove legacy parity coverage.
## Testing
Add streamed compaction coverage for tool search output trimming and session base instruction token estimates. Update app-server tests to verify started/completed notifications for both local and streamed remote compaction.
GitOrigin-RevId: cea392a6166a9b116ff83708fd9126d5546476e4
## What changed
Move the synchronous review loop, outcome mapping, deadline helpers, and session pool into `codex-guardian-reviewer`. Core supplies adapters for evidence capture, authorization checks, session creation, and event publication through the new host interfaces.
Have `guardian-v2` initialize the reviewer pool and host separately, with the pool managing prewarming, session reuse, concurrent forks, invalidation, and shutdown.
## Testing
Extend the app-server reviewer lifecycle test to cover interrupted concurrent reviews as well as completed reviews, including resuming a reviewer after parent shutdown. Adapt core reviewer tests to use the pool and factory interfaces.
GitOrigin-RevId: 2d69bd20c169b20534764b98cbdb63f38564a530
## 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
Replaying tool outputs under a different model can expand or shrink the history shown to the model if truncation uses the new model's budget.
## What changed
Save the originating history truncation budget on function and custom tool outputs and reuse it during replay, preserving existing tool-specific overrides. Include the existing 20% serialization allowance once, before converting byte budgets to tokens.
Rename the metadata field to `history_truncation_token_limit` while retaining `fallback_token_limit_override` as its serialized name for compatibility.
## Testing
Add regression coverage for resume and fork with different model budgets, including custom tool outputs. Extend unit coverage for existing overrides and byte-budget conversion.
GitOrigin-RevId: a62c8fd3e43198e2252b150fba72f022939c1070
## Why
History recording used the model captured at turn start, so switching models within a turn could apply stale image preparation and tool-output truncation rules.
## What changed
Pass explicit model metadata through conversation recording. Record model responses and tool results using their originating step's settings, and capture the current model for pending input recorded during startup interruption or task completion.
## Testing
Add regression coverage for tool results across a model switch, explicit model selection for plain and annotated history, and image input retained during interruption and completion. Extend model-switching tests to verify that prepared media and item identity survive switching back to a multimodal model in live, resumed, and forked threads.
GitOrigin-RevId: 5bc750c30c334acb9b802cb80fdea01daffa84a1
## Why
After a model change within a turn, tools could still use the turn's original model capabilities, output limits, and telemetry attribution.
## What changed
- Build each step's tool plan from its captured model settings.
- Use those settings for image support and detail, command and MCP output truncation, extension metadata, and tool telemetry.
- Preserve the issuing step's model for delayed command completion events while allowing later `write_stdin` calls to use their own step's output limits.
## Testing
Add regression coverage for model changes within a turn, including tool replanning, Code Mode execution, image handling, MCP tool and resource output limits, extension settings, and delayed command completion.
GitOrigin-RevId: ef991598e89a846889baf770a0c9e12e56886d5d
## What changed
Move assessment parsing and schema, model selection, review outcomes, retry handling, and rejection circuit breakers into `codex-guardian-reviewer`. Update core to use the extracted APIs while retaining session execution and decision enforcement in the host.
## Testing
Move existing assessment, circuit breaker, and retry tests into the new crate, including coverage for transient errors, cancellation, and deadlines.
GitOrigin-RevId: 96ec9989a0066acb012bf3bec0b9f7d8bf11a4ef
## Why
Model switches within a turn can leave extension context using stale model metadata. Skill catalogs, context windows, and metric attribution need to match the model captured for each sampling step.
## What changed
- Pass captured model metadata and step-specific telemetry to world-state contributors.
- Use that metadata for skill catalog budgets and usage instructions, preserving configured budget overrides.
- Supply the captured model's usable context window to turn-context contributors, including when rebuilding context.
## Testing
Add regression coverage for model switches during skill discovery, catalog budgets and metric attribution, and extension context windows after `new_context` and retained-step context rebuilds.
GitOrigin-RevId: c51b40b739a380b9767a54ea8c8ee6de45bf01c8
## Why
Model changes during an active turn could leave context using the turn's initial model and settings, even after requests switched to the new model.
## What changed
- Build model, personality, approval, collaboration, app, plugin, and multi-agent instructions from captured step settings.
- Resolve multi-agent policy from the step's effective reasoning effort.
- Use the captured step's context window for full-context metadata and retain that step when rebuilding initial context for compaction.
## Testing
Add regression coverage for model switches updating context without duplicating updates, delegation policy following selected or model-default reasoning effort, and compaction preserving retained context after a model change.
GitOrigin-RevId: 3615c7a3f13f15fdcce9ad13d23311340e0aea88
## Why
Cancelling a session after persistence opens but while MCP startup is still pending can leave its writer held, blocking a subsequent resume.
## What changed
Create `LiveThreadInitGuard` inside the persistence startup future so it protects the live thread while `tokio::join!` waits for other startup work. Dropping the startup future then schedules writer cleanup.
## Testing
Add a regression test that cancels a resume while MCP startup is blocked, verifies the local writer is released, and resumes the same thread successfully.
GitOrigin-RevId: 57d8624e783a7b993579a6386aea35ba845da0e3
## Why
Guardian request and section cost distributions need shared bucket boundaries across synchronous and asynchronous reviewers so their measurements align.
## What changed
- Add `histogram_with_boundaries` to session telemetry and extension metrics while preserving session attribution.
- Use shared request-token buckets up to 2,000,000 tokens and section-cost buckets up to 16,777,216 for both review paths.
## Testing
Extend telemetry tests to verify explicit bucket boundaries and sample counts, and Guardian integration coverage to check exported request and section metric bounds for both synchronous and asynchronous reviews.
GitOrigin-RevId: e34f6972b3418bac3b061939b62eeeccaec5a299
## What changed
Add `ComposedContext::enforce_budget` to fit evidence within the input token allowance after reserving existing context. Preserve required content and message boundaries, reserve an omission notice, and return an error if required evidence cannot fit.
Carry retention policies through transcript rendering and composition. Protect user messages, protected messages, and the newest five tool entries. Remove oversized optional items first, then evict commentary, older tool evidence, and images in priority order. Add image admission support and record omitted content in truncation observations.
## Testing
Add tests for existing-context reservations, required-message preservation, image omission, framing costs, and protection of the newest five tool entries in both context profiles.
GitOrigin-RevId: 8a0f245bad82f562323b4533442385ddbcb6e541
## What changed
- Record per-section text bytes, estimated text tokens, image bytes, and image counts for synchronous reviews and asynchronous scoring without logging evidence payloads.
- Emit estimated request tokens through `codex.guardian.context.request_tokens`. Synchronous estimates include assembled history, instructions, tool definitions, and output format, and measure the full logical request before WebSocket delta generation. Asynchronous estimates cover the assembled input.
- Add shared context budgeting helpers, including conservative image token reservations independent of encoded payload size and model-aware input limit calculation.
## Testing
Add coverage for separate text and image accounting, image estimates independent of encoded size, and section estimates that bound delivered messages. Extend asynchronous scorer and app-server tests to verify cost metric emission.
GitOrigin-RevId: aed45ecd9c23706f88caa51f2a4f2c77872d3bdb
## Why
Credential brokerage must retain trusted destination hints even when shell environment policy hides them from child processes. Snapshot replay also needs to preserve credential aliases when tokens are short or captured dummy values change.
## What changed
- Add `features.network_proxy.credentials` and preserve provider settings when toggling the proxy. Prevent project configuration from overriding providers or their credential and destination environment variables.
- Use provider metadata throughout snapshot capture and replay, and pass hidden destination context to the broker without exposing it in the child environment.
- Rewrite aliases containing short credentials or previously captured dummies, respecting environment filters and explicit overrides.
- Preserve case-distinct `shell_environment_policy.set` keys so Windows credential ambiguity checks survive configuration merging and permission profile changes.
- Restore independent MITM settings when credential brokerage is disabled.
## Testing
Add regression coverage for custom providers, hidden destination hints, Bash and Zsh alias replay, configuration edits and merging, Windows ambiguity handling, and credential protection during approved execution.
GitOrigin-RevId: b2bd935d2d8555be56baf8feb1a8e5b3a0c666bc
## What changed
Increase `GUARDIAN_MAX_ACTION_BYTES` from 8,000 to 200,000 bytes to allow larger actions to be reviewed. Keep unified exec stdin approvals capped at 8,000 bytes with a separate `MAX_STDIN_APPROVAL_BYTES` constant.
## Testing
Update aggregate payload rejection coverage for the new limit and exercise MCP elicitation reviews with tool descriptions exceeding the previous 8,000-byte limit.
GitOrigin-RevId: fd4b97980803a7a687449043931e6f1e57e260d3
## What changed
Pass `StartThreadOptions` through rollout, loaded-history, and prepared forks instead of separate configuration and startup arguments. Replace `options.initial_history` with the fork snapshot while preserving the other supplied startup options, and update app-server and test callers.
Box the app-server's `thread_fork_inner` future to keep the large fork future out of the shared request dispatcher's stack frame.
GitOrigin-RevId: d54eb8b212dedabaf2c5d99d155637cefd7deb7a
## Why
Shell quoting can hide credentials from raw-text checks, and startup files can restore real credentials after the broker replaces them with dummy values.
## What changed
- Decode shell literals without evaluating them and reject snapshots containing credentials in executable source, including aliases, functions, and heredocs.
- Preserve credential policy overrides, explicit unsets, and aliases whose source variables were removed. Support credential aliases in Zsh tied arrays while rejecting credentials that span array elements.
- Guard snapshot replay against credential restoration through shell startup files and preserve unrelated `ENV` settings.
- Apply Windows environment-key casing rules to credential overrides, suppress unredacted sandbox diagnostics during snapshot capture, and clear inherited environment variables before launching escalated commands.
## Testing
Add regression coverage for shell quoting and escaped credentials, Zsh tied arrays, startup-file replay, readonly credentials, policy overrides, and sensitive capture timeout and cancellation handling.
GitOrigin-RevId: 58274c07c715423241d26ce6dd2c2b4230cf0f64
## What changed
Support `model_providers.amazon-bedrock.aws.credential_export` with `command`, `args`, and `timeout_ms` to supply SigV4 signing credentials from a command's JSON output. Accept both flat credential-process output and nested STS `Credentials` objects.
Cache credentials in memory, refresh before expiration, and share exports across sessions with matching AWS configuration. On recoverable authentication failures, run the optional `aws.auth_refresh` command before exporting fresh credentials, coalescing concurrent recovery attempts.
Bound command execution time and output size, and keep credential values out of errors. Reject combining `aws.credential_export` with `aws.profile`. Bedrock setup and login reject changes while an exporter is configured, preserving configuration and saved credentials.
## Testing
Add coverage for output formats, expiration, credential precedence, caching, concurrent recovery, command failures, and secret redaction. Integration tests verify request signing with rotated credentials, bounded recovery attempts, and setup/login rejection across configuration layers.
GitOrigin-RevId: 4ef799f88ab5e3b2578f8f41a5e56e4f30e2cd81
## What changed
Introduce `ExecutedToolCalls` to own optional shared recorder state and centralize feature checks, call recording, and accepted result source lookup. Update session, tool runtime, MCP, and Code Mode callers to use this interface.
Move prompt attachment, retry handling, and metadata budgeting into the `request_metadata` module, preserving existing recording and request behavior.
## Testing
Add coverage for all session and turn feature combinations, lazy result source lookup, and unchanged prompts when recording is disabled. Retain the existing metadata budget and cell completeness tests in the new module.
GitOrigin-RevId: bc19f34317232b6599c7ec71c15db4a80123ff6f
## Why
Credential-brokered commands rebuild shell snapshots on every invocation. Snapshot capture failures can also include credential-bearing startup output, and descendants holding output pipes need cleanup even after the shell exits.
## What changed
- Cache successful protected snapshots per environment, keyed by working directory, shell, login mode, and sandbox configuration. Rebuild missing or stale snapshots while keeping concurrent captures independently cancellable.
- Invalidate snapshots when shell settings or credential broker configuration change, and retry capture once if broker configuration changes during startup.
- Restore credentials and associated provider context while respecting environment policy filters and explicit overrides.
- Keep full-buffer capture subject to timeout and cancellation through output draining, clean up descendants on capture expiration or drain failure, and omit startup output from snapshot errors.
## Testing
Add regression coverage for snapshot reuse, invalidation, recovery after storage failure, concurrent cancellation, credential-safe errors, and descendant cleanup. Verify that successful background startup and output beyond the shell output cap remain supported.
GitOrigin-RevId: 7c7c8455bf6e3b9ca173dbb4277783469f0b45e6
## What changed
Parse optional `generation_id` values from image API responses and carry the selected image's ID through the image generation tool into analytics events. Keep the ID out of serialized extension items, JSON schemas, and TypeScript types. Responses without an ID remain supported.
## Testing
Add coverage for distinct IDs in multi-image responses and responses without IDs. Extend analytics and app-server tests to verify that the selected image's ID reaches analytics, and item tests to verify that it is omitted from serialization and TypeScript types.
GitOrigin-RevId: 70a600856990140b76fdbda51a0d73b3414338b1
## Why
Hosts need to stop new turn-input work during shutdown without consuming pending input or preventing already-running delegated work from finishing.
## What changed
- Add an optional `TurnStartAdmission` extension gate, checked before reserving or starting a new turn. Hosts without a gate retain existing behavior.
- Return `NotSubmittedReason::ServerDraining` for refused starts and surface an app-server error instructing clients to reconnect and retry.
- Keep steering, parent-delegated subagent input, and memory-only mailbox wakeups available during drain, while gating automatic starts.
- Close realtime conversations with an ordered handoff, error, and close event sequence when a handoff is refused during drain.
## Testing
Add regression coverage for rejected input staying out of subsequent requests, persisted queue items remaining available for later starts, delegated agent and review work completing during drain, mailbox wakeups, and realtime handoff error ordering.
GitOrigin-RevId: 03dbdcd71eab200e597c0649e6eb39bd92dbc82f
## Why
Filesystem policies for remote execution need to interpret paths, home directories, and temporary directories using the execution host's context.
## What changed
- Add context-based read-denial matching, read-access checks, glob resolution, and `PathUri` workspace-write constructors without consulting local paths or environment variables.
- Share managed read-denial validation through `DenyReadValidator` and use it in core configuration, preserving required-entry checks, concrete grant validation, and constraint diagnostics.
- Reject invalid or unresolvable denial paths when constructing a context-based matcher, and apply `/tmp` denials according to the execution host's path convention.
- Preserve workspace-root symbols and protected metadata entries when materializing URI-based writable roots.
## Testing
Add regression tests for POSIX, Windows, and UNC path matching; conflicting read and write grants; malformed or unresolvable denials; `/tmp` handling; and workspace metadata protection.
GitOrigin-RevId: aa2b174288d1172ab52ff485f58d306236d27652
## What changed
- Update the status heading from the latest usable reasoning line and retain it through tool activity and empty reasoning items. Keep completed reasoning in the expanded transcript only.
- Restore active reasoning after resume, thread switches, and session refreshes, including when earlier events have left the replay buffer.
- Default new embedded TUI threads to `model_reasoning_summary = "detailed"`, honoring explicit summary settings. Keep `concurrent_reasoning_summaries` opt-in and disable it when summaries are `none`.
- Persist the request's captured reasoning summary setting in context updates and local and remote compaction checkpoints.
- Animate status text with a smooth, grapheme-aware shimmer that respects terminal colors and reduced motion.
## Testing
Add regression coverage for reasoning status updates, transcript visibility, resume and buffered replay, outbound summary configuration, and summary settings across all three compaction modes. Add shimmer snapshots and checks for smooth brightness changes and Unicode grapheme preservation.
GitOrigin-RevId: 725c7de20f23166d7a3da6daeca617add5cbc600
Add `CodexThread::queued_event_count()` to support a finite event drain
before transferring the receiver. Callers must remain the sole event reader
until they consume the snapshot count, leaving later events for the next reader.
GitOrigin-RevId: 55f9dd1cf8ebd396fdb60a1dc3d1428ed28cc2d2
## What changed
Add tracing spans for `AGENTS.md` discovery and loading, local file reads and metadata lookups, and filesystem sandbox request preparation and execution. Record the instruction byte limit, whether file operations use the sandbox, and the permission entry count during sandbox preparation, while skipping automatic argument capture.
GitOrigin-RevId: a6aab1cbac975f8042ce48d6a238c48816f7bd77
## Why
Guardian reviewers can inherit token-budget mode from the parent session or model defaults, causing context rollover instead of summary-based compaction.
## What changed
Clear inherited token-budget startup activation, set an explicit default `TokenBudgetConfig`, and disable `Feature::TokenBudget` and `Feature::ContextManagement` for Guardian review sessions.
## Testing
Update regression coverage to verify that reviewers compact with a summary even when the parent and model enable token budgets. Cover both transcript modes and browser evidence, checking that review requests omit `token_budget.context_window` and retain the compaction summary.
GitOrigin-RevId: e1a84f9c7752a712399cd749c3834b2a7bb4a7e6
## Why
Shell startup files can introduce credentials or overwrite brokered dummy values. Snapshot capture and replay need to respect the command's sandbox and environment policy without persisting real credentials.
## What changed
- Capture and validate brokered snapshots per command using its requested shell, working directory, login mode, sandbox, and environment policy.
- Discover shell-initialized credentials and prepare snapshot exports for brokered replay. Preserve shell functions and aliases while preventing startup files from overwriting dummy credentials during replay.
- Rebuild snapshots as credential broker state changes and retain each command's snapshot for the lifetime of its process.
- Reject brokered POSIX shell execution when a protected snapshot cannot be created, and reject brokerage with `shell_zsh_fork`. Restore real credentials and remove brokerage markers for unsupported PowerShell and Cmd execution; escalated commands bypass protected snapshots.
## Testing
Add regression coverage for credential discovery and redaction, environment filtering, readonly exports, shell function and heredoc replay, command working directories and login modes, sandbox enforcement, and missing or disabled snapshots.
GitOrigin-RevId: 685356cb9e80f11cf69d053e4d239ee6ccf43a9e
## Why
Line-based export parsing can truncate multiline values or mistake their contents for declarations. Snapshot replay also needs to restore Bash options before parsing functions that use extended glob syntax.
## What changed
- Capture shell state, aliases, and complete export records with NUL-delimited boundaries, separating capture, credential preparation, and rendering.
- Apply credential and environment policy to whole exports, preserving multiline values and making credential aliases follow allowed overrides.
- Restore Bash `shopt` options before functions, including for Bash running as `sh`.
- Support non-evaluating POSIX `ENV` path expansion and preserve native environment metadata and unset exports.
- Move core and exec-server snapshot consumers to the shared capture parser. Allow capture overhead while enforcing the exec-server's 512 KiB state-and-environment limit before filtering.
## Testing
Add regression coverage for complete capture records, multiline export filtering and replay, credential alias overrides, `ENV` expansion, and `PATH` export state. Extend exec-server tests to cover Bash-backed `sh`, `extglob`, `nocasematch`, `set -u`, and large environments.
GitOrigin-RevId: 7589ab4d137529a395dcee10b5162718de24a621
## Why
Code-mode callbacks can resume outside the turn's local span ancestry, leaving tool dispatch traces without the thread identity inherited from a turn span.
## What changed
Record `thread.id` directly on the `dispatch_tool_call_with_code_mode_result` span using the session's thread ID.
## Testing
Add a regression test that dispatches a code-mode tool callback from a fresh task without a turn span and verifies that the dispatch span records the thread ID, tool name, and an `exec-` call ID with a valid UUID.
GitOrigin-RevId: a25a0d8fcaf1b6501473151c486fc9940065df91
## Why
Resuming a thread should retain its selected workspace folders, including additional roots and explicit empty selections. Resume overrides also need to survive a subsequent resume when no turn has run.
## What changed
- Persist `runtime_workspace_roots` in startup metadata and thread settings snapshots, separately from explicit environment selections and permission-profile roots.
- Restore roots from the latest snapshot owned by the resumed thread, falling back to owned startup metadata only when no snapshot exists. Honor explicit `runtimeWorkspaceRoots` overrides, retarget the old `cwd` root when `cwd` changes, deduplicate roots, and validate restored paths for the current host.
- Checkpoint effective settings on resume and restored settings after revert. Reload resume configuration if saved workspace roots change during loading.
- Normalize Windows rollout path spellings when matching thread search results, preserving selection of the correct rollout after revert, including compressed rollouts.
## Testing
Add regression coverage for workspace restoration, empty and explicit overrides, foreign paths, compaction and revert, resume checkpoints without recency changes, concurrent settings persistence, and rollout search path matching.
GitOrigin-RevId: d98d9d34dd63934d441120916c61c12b69e7f062
## Why
Enterprise sign-in needs to keep browser completion separate from credential storage so callers can recheck the active account and configuration before saving a grant. Logout must also prevent an earlier sign-in from restoring credentials, including from another process sharing `CODEX_HOME`.
## What changed
- Add enterprise login APIs in `rmcp-client` that return an authorization URL and stage validated credentials for an explicit `commit_if` call. Store grants only in the keyring after rechecking caller authority under the credential lock.
- Require a registered client ID, published metadata matching the configured issuer, HTTP loopback callbacks, a refresh token, and a valid OIDC identity assertion. Request `openid` and `offline_access` with `prompt=consent`, and omit MCP resource indicators from authorization and code exchange.
- Persist a login generation under the credential lock so logout invalidates pending and staged sign-ins across processes, even when no grant is stored.
- Keep credentials and account identifiers out of enterprise error chains and logs, and avoid logging callback payloads when the receiver has closed.
## Testing
Add coverage for discovery validation, loopback callbacks, PKCE, staged keyring storage, cancellation, stale attempts, cross-process logout, and error/log privacy. Preserve ordinary MCP OAuth login without a refresh token, and adjust the terminal polling test deadline to include the minimum empty-poll wait.
GitOrigin-RevId: 2a27b9a26505a2f6fdecce8877f6e2c21e148f72
## Why
Allow v2 memories to build in the background while the selected memory version continues supplying context, and let clients check whether v2 has enough consolidated data and a valid summary to use.
## What changed
- Add `memories.dual_write`, disabled by default, to run v1 and v2 extraction and consolidation concurrently with separate stores and directories.
- Add the experimental `memory/status` endpoint, returning `v2ConsolidatedThreads` and `v2Ready`. Readiness requires a valid v2 summary and a consolidation thread count meeting `minConsolidatedThreads` (default 20, supported range 1–4096).
- Persist the largest thread count from a successful consolidation across pruning and clear it on memory reset.
- Share v2 summary validation between consolidation and status reporting, and tag memory metrics with `memory_version`.
## Testing
Add tests for independent dual-write outputs, preserving existing notes without importing them into v2, and readiness behavior across consolidation ownership checks, missing summaries, configurable thresholds, thread deletion, and memory reset.
GitOrigin-RevId: 54417cc60bf419062401355c0da8c79119995f61
## What changed
- Consolidate v2 rollout summaries into `memory_summary.md` without generating `raw_memories.md` or requiring `MEMORY.md`. Validate the summary's required sections and size below 10,000 UTF-8 bytes.
- Add v2 read instructions for selective history retrieval, evidence-grounded preferences, citations, and explicit memory edits. Split injected instructions into fragments to preserve the complete summary within fragment byte limits.
- Record memory citation usage in the store selected by `memories.version`.
## Testing
Add coverage for v2 consolidation without a handbook, summary validation, version-isolated memory reads, and resetting both memory versions while preserving threads.
GitOrigin-RevId: 1d895fb4a23a973f1a45ba03be07a1f480c10227
Move `extraction_messages` from `MemoryContextFragment` in `codex-core` to
`codex-rs/memories/write/src/rollout_input.rs` and update the phase-one caller.
Preserve the existing 8,900-byte chunk limit and Unicode-safe boundaries.
Move the accompanying test with the helper, retaining coverage that bounded
user messages reconstruct the original evidence without loss.
GitOrigin-RevId: 48ac501acbfa50c4195195fd40efc7588a6c714d
## What changed
Add `ContextProfile` to `codex-guardian-context` and route synchronous and asynchronous Guardian transcript rendering through it. Move default limits, retention, formatting, and async chunked eviction into the shared crate while preserving the distinct retention policies and host-managed full/delta cursors.
Carry transcript truncation observations through `RenderedTranscript` into context composition, and derive async image collection flags from the resolved profile.
## Testing
Add a profile regression test covering distinct sync/async retention priorities, original entry numbering, omission notes, and async truncation observations. Adapt existing transcript tests to the updated input API.
GitOrigin-RevId: 7f7dc249629d8017e9547085f6617f815ae43a1b
## Why
Synchronous approval reviews and asynchronous scoring assemble Guardian evidence separately, duplicating transcript framing and section placement.
## What changed
- Move evidence ordering, framing, and delivery into `codex-guardian-context`, while keeping transcript retention, budgets, and delta cursors with their callers.
- Pass composed messages directly to the asynchronous sampler, preserving roles, annotations, trusted message boundaries, and image placement.
- Reject unsupported synchronous delivery with `SectionError::UnsupportedDelivery` instead of silently dropping content.
## Testing
Add composition coverage for preserving separate messages and rejecting them for synchronous delivery. Extend Guardian integration coverage to check trusted tool and skill messages, mixed text and image evidence ordering, and full and delta review framing.
GitOrigin-RevId: efc06695ee4e2b7400b123b77ef2a21c8bf40646
## Why
Memory extraction has a limited rollout budget. Select evidence by source so human input and assistant final responses take priority over commentary, context, and tool output.
## What changed
- Use tiered selection for memory v2, preferring newer evidence within each tier and rendering selected items in chronological order with omission markers.
- Keep answered `request_user_input` questions alongside human replies, label evidence sources, replace message media with placeholders, and bound tool output and individual rows.
- Add typed memory context fragments with bounded messages and Unicode-safe extraction chunking.
## Testing
Add tests for memory v2 startup using tiered input and for extraction chunks preserving Unicode evidence within message bounds.
GitOrigin-RevId: 1b2bba4e3264b4fda271e429ad3b7d5f69caed59
## What changed
- Add `memories.version` with `v1` as the default and `v2` as an opt-in selection.
- Route memory generation, summaries, and retrieval tools through the selected version. Store `v2` artifacts in `memories_v2` and lazily create a separate SQLite database, keeping jobs and outputs isolated while sharing the thread catalog.
- Preserve the initial memory version across extension config updates so summaries and retrieval tools use the same namespace.
- Clear both versions on memory reset and remove thread memory from both stores on thread deletion. Recognize both artifact roots in shell usage telemetry.
## Testing
Add regression coverage for version defaults and validation, independent job claims and outputs, deletion and reset across versions, and shell usage classification for both memory roots.

## Why
With reasoning effort overrides enabled, compaction used the selected effort even when sampling requests still used an earlier pinned effort. Successful compaction also left that old pin active in the new context window.
## What changed
- Use the pinned request effort for local and remote compaction when it matches the model.
- Resolve fallback models' effort without mutating the live pin, preserving it if compaction fails.
- Reset the pin after successful compaction so the next sampling request establishes the selected effort as its baseline without a redundant `configuration_update`.
## Testing
Add regression coverage for remote compaction success and failure, fallback model effort selection, pin preservation during fallback lookup, and compaction after resuming with overrides disabled.

## Why
Reasoning-effort changes should preserve the request baseline while trusted `configuration_update` items carry the selected effort.
## What changed
- Pin request-level reasoning effort for the current model when reasoning-effort overrides are available, including during WebSocket prewarm.
- Re-establish the selected effort after rollback, resume, or a model switch, refreshing the trusted override even when the selection is unchanged.
- Continue using the selected request effort when overrides are unavailable.
## Testing
Add regression coverage for WebSocket prewarm and reconnect, rollback, resume, and model switches. Update transition tests to assert that request-level effort stays pinned while configuration updates change.

## What changed
Add `tui.show_server_version_notice`, enabled by default. Set it to `false` to suppress informational notices about older stable app servers at startup, on reconnect, and in the agents overview. Compatibility errors and version status remain unaffected.
Refresh the overview notice when local settings change, clearing pending notices when the setting is disabled.
## Testing
Add coverage for disabling and re-enabling overview notices, clearing pending notice state, and preserving remote version status. Extend reconnect and local-settings tests to cover the new setting.

## What changed
Add `is_worktree` to thread initialization analytics and the `codex.thread.started` metric using validated Git repository metadata. Classify linked worktrees as `true` and primary checkouts as `false`; report an unavailable classification as `null` in analytics and `unknown` in metrics. Subagent initialization analytics leave the field unset (`null`).
## Testing
Add analytics coverage for primary checkouts, linked worktrees, unknown repositories, and event serialization. Extend the account-switch telemetry test to check that the `is_worktree` tag reaches the next account's collector.

## What changed
Move completed REPL response rendering into `codex-guardian-context` and register a synchronous-only `NodeReplEvidence` section. Core supplies a borrowed view of its evidence snapshot and retains responsibility for capture, storage eviction, and the delivery cursor.
Preserve the existing text and multimodal layouts, rendering bounds, omission markers, image ordering, and deduplication. Exclude evidence payloads from the rendered section's debug output.
## Testing
Adapt the existing evidence tests to exercise the shared renderer. Extend registry coverage to verify synchronous-only inclusion, rendered content, and omission of evidence payloads from debug output.

## What changed
Move bounded transcript image collection into `codex-guardian-context` and expose it through an optional `TranscriptImages` section. Update the async scorer to consume this section, preserving source filtering, image detail, omission accounting, and the existing limits of four images and 8 MiB of image URL data.
## Testing
Add coverage for source order, tool-output filtering, disabled image collection, oldest-image eviction, oversized images, and omitted-byte accounting.

## What changed
Move trusted skill rendering into `codex-guardian-context` as `TrustedSkills` and collect it through an async-only context section. Pass the collected section to the sampler, preserving the separate developer message and bounded JSON rendering. Omit skill paths from `Debug` output, exposing only their count.
## Testing
Move rendering tests alongside the shared type, covering multiple paths and escaped UTF-8 within the size budget. Extend registry tests to cover async-only inclusion, omission for empty input, section ordering, and path redaction in debug output.

## What changed
Represent host-verified tool metadata as `TrustedTool` in `codex-guardian-context` and collect it through an async-only context section. Route Guardian v2 sampling through that section while preserving separate developer-message delivery and the 512-token rendering budget. Omit tool metadata from debug output.
## Testing
Move the rendering-budget test into the shared crate, extend registry coverage for async-only collection and debug redaction, and narrow the scoped approval test to messages tagged `guardian.trusted_tool`.

## What changed
Move prior-review rendering and developer-message construction into `codex_guardian_context`, and route async scorer evidence through a dedicated `PreviousReviews` context section.
Validate a maximum of eight review fragments and a per-fragment byte budget equivalent to 1,000 approximate tokens. Reject oversized evidence without rewriting or dropping records, and fail closed when validation fails. Preserve authorization-version filtering and the existing developer-role delivery. Keep review contents out of debug output.
## Testing
Add coverage for count and UTF-8 byte-size boundaries, preservation of accepted fragments, async-only section delivery, and omission of review contents from debug output.
