## What changed
- Tell the model that generated images are already displayed to the user and should not be repeated as Markdown images or file links.
- Keep generated-image artifact paths and output hints owned by the image generation extension.
- Centralize the availability check for the image generation tool across feature, provider, namespace-tool, model modality, and authentication requirements.
## Testing
- Verify artifact paths sanitize session and call identifiers.
- Verify the model-facing output hint reports that the generated image is already displayed.

## Why
Requests longer than 10 seconds were grouped into the overflow bucket, limiting visibility into long-running request latency.
## What changed
Add second-based duration histogram boundaries at 12, 15, 20, 30, 60, and 120 seconds.
## Testing
Extend the duration histogram test to cover every new boundary and a 121-second overflow value.
GitOrigin-RevId: 063a5d397dbd37d3b3940c7a1632b7b479e874a4
## Why
Pending Guardian review state could outlive an interrupted or completed turn,
leaving stale review details visible during a following goal turn.
## What changed
- Clear pending Guardian reviews during both turn completion and finalization.
- Restore an active MCP startup header after cleanup, falling back to `Working`
when no MCP server is starting.
## Testing
Added coverage for interrupted and completed turns, including goal continuation
and overlapping MCP startup status.
GitOrigin-RevId: a15ed81a5d6005e9294089f4424a8dedbc6e9cb5
## Why
The TUI already receives skill metadata from the app-server protocol, but converted it into the core-skills model before using it.
## What changed
- Use `codex_app_server_protocol::SkillMetadata` throughout skill toggles, mentions, and input submission.
- Remove the protocol-to-core conversion and the TUI's `codex-core-skills` dependency.
GitOrigin-RevId: 43d43d74bfb67fc21ef11a0ca0592aa44b89a122
## What changed
Add a borrowed `Line` conversion and use it when rendering and measuring
hyperlink-aware history and pager content. This preserves line styling and
alignment while avoiding clones of the underlying span strings.
GitOrigin-RevId: c9cd6ff5ec63cd29719ea2ae51acede7364f2bd8
## What changed
- Add one-shot composer and status-line transitions when the active reasoning effort changes to Max or Ultra.
- Keep a tier-specific prompt accent after the transition, including a distinct Ultra prompt glyph.
- Preserve drafts and footer priority, avoid replaying effects for restored or unchanged settings, and disable motion when animations or sufficient terminal color support are unavailable.
## Testing
- Add unit and snapshot coverage for animation frames, prompt accents, status-line transitions, narrow layouts, terminal palettes, restored sessions, and reduced-motion behavior.
GitOrigin-RevId: 6da1d501d228d0cf1144b3d211d5d1304a06f447
## What changed
- Resolve the turn ID for restored token usage before sending resume and fork responses, avoiding a clone of the full thread history.
- Add `ThreadHistoryBuilder::active_turn_id` so attribution can inspect the active turn without materializing its items.
- Stop history reconstruction at the latest persisted `TokenCount` and verify that a later tail turn does not receive the replayed usage.
GitOrigin-RevId: 69c4a9fe04770d1a938470afc933431e61670094
## Why
Large command streams, including commands that never emit a newline, can make an active TUI cell grow without bound.
## What changed
- Retain live output in full up to 1 MiB, then preserve the first and last 50 completed lines plus the current partial line.
- Bound individual long lines while preserving UTF-8 boundaries, visible head and tail content, and ANSI rendering around omission markers.
- Show omitted line and byte counts in previews and transcripts. Final command output still replaces the bounded live preview when execution completes.
## Testing
Added unit and snapshot coverage for chunk boundaries, split CRLF sequences, newline-free and UTF-8 output, truncated ANSI sequences, retained-output limits, and preview and transcript rendering.
GitOrigin-RevId: 3cf3cc862db686f20ac09b1f6e7f9dc6d264e6eb
## What changed
- Encapsulate aggregated command output behind APIs for total and retained line
counts, reversible preview iteration, and full transcript iteration.
- Build truncated command previews from the retained head and tail lines while
preserving the logical omitted-line count.
- Cover head/tail rendering for long streamed agent and user-shell output.
GitOrigin-RevId: 54b23a19e4639e24c5e4778082edbbc6484ecf80
## Why
During TUI startup, `hooks/list` holds the global config queue while an
uncached `model/list` request may also take time. Waiting for
`configRequirements/read` before submitting the model request prevents these
operations from overlapping.
## What changed
Submit `model/list` and `configRequirements/read` together during bootstrap so
the model fetch can overlap the config requests. Preserve the request-specific
error context and update the session state after both requests succeed.
GitOrigin-RevId: 69a866e6d2fd4798b914dd000456194f49fcfef6
## Why
Sizing, rendering, and cursor placement can query the same chat widget layout
multiple times in one frame, repeatedly measuring active transcript cells.
## What changed
- Build one chat widget renderable tree per frame and reuse it for sizing,
rendering, and cursor placement.
- Cache each flex child's desired height by width for the lifetime of that tree.
- Reuse the bottom pane's renderable directly instead of forwarding each
renderable operation through a wrapper.
## Testing
- Verify flex layouts measure a child once across frame passes and remeasure it
when the width changes.
- Verify a chat widget frame measures its active transcript cell once.
GitOrigin-RevId: 5ad1a6711f4011c699b5d002b13dc3319cb4db8e
## What changed
- Move lifecycle and approval payloads into either the interrupt queue or the
immediate handler instead of cloning them for both branches.
- Borrow MCP elicitation request metadata while constructing the corresponding
form, and consume apply-patch changes after collecting notification paths.
## Testing
- Add a history replay test confirming deferred MCP start and completion events
remain FIFO after streaming finishes.
GitOrigin-RevId: 84ed34f6ff173463a1da016dc140405392c0ba45
## What changed
- Record when committed streaming content contains an inline visualization directive and keep using the canonical full-source renderer afterward.
- Restore directive state during full recomputes and clear it when the streaming renderer is reset.
- Cover directive tracking with and without visualization context, including a raw-to-rich render mode switch.
GitOrigin-RevId: 17786851d6dad6805240b79072fcbd0bb441874a
## What changed
- Remove unused APIs and test helpers across the Rust workspace.
- Route Linux sandbox test setup through the shared exec request path.
- Drop dependencies that became unnecessary after the cleanup.
GitOrigin-RevId: 48fd9b2b1575bad7add0819786b4d8ec88d8486f
## Why
The first session metadata record defines a rollout's history mode. If that
record uses an unsupported mode, skipping it as a parse error can cause later
metadata copied from fork history to be treated as canonical.
## What changed
- Validate session metadata history modes before deserializing rollout lines,
while continuing to tolerate unknown modes in copied fork history.
- Simplify thread status registration to pass only the thread ID instead of a
fully materialized `Thread`.
GitOrigin-RevId: 9de4313d4a76b279d32bb49b2016a4f5d07507c1
## Why
zsh prints tied scalar/array exports such as `PATH` and `path` with `-T`
metadata. The snapshot filter rejected that syntax, so commands available only
through the configured `PATH` could not be resolved from a restored snapshot.
## What changed
- Recognize writable tied exports and retain them in zsh shell snapshots.
- Skip readonly exports so restoring a snapshot does not make variables such as
`PATH` immutable.
## Testing
Added macOS coverage for restoring a tied `PATH`, handling entries with spaces,
deduplicating path entries, excluding readonly tied exports, and resolving a
command available only through the restored snapshot.
GitOrigin-RevId: 297cfae3368230c7f6fe5ef84f0a10b35a2c802c
## What changed
- On session startup, remove exact `allow` entries from `rules/default.rules`
for command prefixes that Codex no longer suggests as policy amendments.
- Record the migration in `.sandbox_migration` so it runs only once, preserving
rules created after the migration.
- Skip the migration when user and project exec policy rules are ignored.
- Expand the protected prefix list across shells, interpreters, package runners,
and destructive or privilege-related commands.
## Testing
- Cover selective removal, case-insensitive matching, one-time behavior, and the
startup path with ignored policy rules.
GitOrigin-RevId: a0c60e3f82b9630e621fd034b40462e3ab775102
## What changed
- Skip loaded-subagent backfills for fresh and forked threads, which cannot have pre-existing descendants.
- Keep the backfill after resuming a thread so agent navigation is populated immediately.
- Reuse thread status collected during backfill when opening the agent picker, avoiding duplicate `thread/read` requests while preserving liveness from live event channels.
## Testing
- Add a WebSocket-backed session lifecycle test that records app-server requests across fork, fresh-session, resume, and agent-picker flows.
GitOrigin-RevId: 604742b3cb495da12c97908d7a0ffa4ebc6a6da3
## Why
The transcript overlay cached every committed cell's height. Cells whose content changes after insertion, such as refreshed status output or newly available visualizations, could outgrow that cached height and be clipped.
## What changed
- Let history cells declare whether their transcript height is stable, and remeasure dynamic cells on later overlay renders.
- Preserve cached heights for stable cells when appending a committed cell instead of rebuilding all renderables.
## Testing
- Cover status output growing after a rate-limit refresh.
- Cover a visualization link replacing its unavailable placeholder.
- Verify that appending a cell preserves cached measurements for stable cells.
GitOrigin-RevId: 03e7166cb94d7353c9b89bff8abb3b7ccb84a6bb
## Why
Paginated threads need explicit user-facing names to remain distinct from
derived titles and previews without requiring rollout metadata writes.
## What changed
- Add a nullable `name` column to persisted thread metadata and use it as the
canonical name for paginated threads.
- Route paginated name updates through the state database while retaining the
name index as best-effort compatibility data and preserving legacy thread
behavior.
- Return persisted names when reading, listing, searching, and resuming
paginated threads, and include them in state-database search matching.
## Testing
- Cover paginated name updates, reads, list/search results, and metadata-only
resume behavior, including stale or unavailable compatibility data.
GitOrigin-RevId: 5ac4dfa2a83682b43d59ecc87e0f515580164dca
## Why
Multi-agent exec sessions can receive child `turn/completed` notifications on
the same event stream as the primary turn. Backfilling those unrelated
completions issues unnecessary `thread/read` requests.
## What changed
Run completion-item backfill only after a notification has been matched to the
primary exec thread and turn.
## Testing
Add an integration test that delivers a child completion before the primary
completion and verifies that only the primary completion triggers backfill.
GitOrigin-RevId: 46a41236ee6a39e4b341570ff4826a71fa02bb32
## What changed
- Consume and sort `DiffSummary` entries directly when building renderables.
- Borrow paths and `FileChange` values in the shared row representation used by line-based summaries.
- Share line-count calculation between both rendering paths.
GitOrigin-RevId: b02668074def7529ff39445e9970a1fec209f02b
## Why
Finalized Markdown can be rendered repeatedly at the same width while measuring and displaying transcript history.
## What changed
- Cache the latest rendered lines for finalized agent messages and proposed plans.
- Invalidate cached lines when the width, syntax theme, terminal colors, or color level changes.
- Keep visualization directives uncached because resolving their local files depends on current filesystem state.
## Testing
Add tests for cache reuse, render-state invalidation, raw Markdown rendering, and visualization cache bypass.
GitOrigin-RevId: ba08140041a229b8cb9d297de87dc7bb39ebfe5d
## Why
Raw response items, realtime audio, and other notifications that the TUI does
not consume during replay can carry large payloads. Retaining them in each
thread's replay buffer wastes memory and can evict useful buffered events.
## What changed
- Skip replay buffering for notification types that are handled before routing
or ignored during replay, while still updating turn and approval state.
- Borrow notifications when recording events for an active thread so routing
does not require an extra clone.
## Testing
Add coverage that repeatedly sends large MCP progress and realtime audio
notifications and verifies that the replay buffer, pending approval, and active
turn state remain intact.
GitOrigin-RevId: 5b3414f1db7f3ae1feea4fe6c0275e4a7a1a4174
## Why
App-server command output deltas populate an exec cell before the command
finishes. Treating the presence of output as completion can therefore mark a
streaming command inactive too early and mishandle it when the turn is
interrupted.
## What changed
- Use the recorded duration, which is set when a command ends, as the exec
call's completion marker.
- Preserve streamed output when marking unfinished calls as failed and render
status lines only after completion.
- Keep a single aggregated output representation and render truncated output
without collecting every line first.
- Append grouped exploration calls in place and coalesce adjacent reads while
rendering without cloning the calls.
## Testing
- Add snapshots covering active streamed output, transcript output, and the
resulting history entry after interruption.
- Add coverage for truncating newline-dense output.
GitOrigin-RevId: 420ac1e5fe1b9fcdbdaa5a8998f3e43a5b720254
## Why
Providing an inline visualization context forced every streamed Markdown update
to rerender the full response, even when the source contained no visualization
directives.
## What changed
- Preserve the stable rendered prefix when visualization context is available
but no directive is present.
- Continue using canonical full rendering when the source contains a
visualization directive.
## Testing
Added a regression test that verifies directive-free streams match full
rendering while advancing the stable source boundary.
GitOrigin-RevId: cd70d2ba052db822d474eba8619d04cedf4c0573
## What changed
- Allocate Markdown table widths in bulk while preserving the existing column
shrink priorities and balancing behavior.
- Reuse flattened styled-line data during adaptive wrapping and detect URLs
across span boundaries.
- Remap wrapped terminal hyperlinks with a single forward scan.
## Testing
- Verify bulk table shrinking matches the previous one-cell-at-a-time results,
including a token-heavy column with a million-character width.
- Cover URLs split across styled spans and multiple links on indented Unicode
lines.
GitOrigin-RevId: 24a6fd6fdace6ca948e613d67c130a3a7f8d1a4e
## Why
The MCP image output cell only renders a fixed placeholder, so it does not need
to keep the decoded image alive for the lifetime of the history cell.
## What changed
Decode image content to validate it, then return a marker cell without storing
the resulting `DynamicImage`. The rendered history output remains unchanged.
GitOrigin-RevId: b2c12d08e8ba281d2bb993a8524d338c26d52b96
## What changed
Make the hyperlink-aware history insertion helper accept a slice and borrow
pending history batches when flushing them. This avoids cloning each batch's
entire `Vec<HyperlinkLine>` before insertion.
GitOrigin-RevId: 0bc86c33e2f047c62de60b7642899c4aaa4bb6b8
## Why
The `thread/started` notification for a newly forked side conversation can arrive after the fork response. Selecting the side thread in that window could incorrectly report that it was unavailable.
## What changed
- Seed agent navigation from the side-fork response before selecting the new thread.
- Skip redundant liveness and parent-title reads for side threads that already have local state, while preserving liveness checks for uncached agent threads.
## Testing
- Cover side-thread selection before `thread/started` is delivered.
- Verify uncached threads are still checked and regular forks still resolve their parent title.
GitOrigin-RevId: 1f9fb0586db8094bf5a2624bc4e1de06c9a783a1
## What changed
- Fork side conversations with `exclude_turns` so their initial UI starts empty instead of displaying the parent thread's turns.
- Keep regular fork responses unchanged, including for ephemeral threads.
## Testing
- Add coverage that compares regular and side-conversation forks of the same saved thread.
GitOrigin-RevId: 662607e9f588c20a2e06656deefa5b70bde19cd2
## What changed
- Return committed byte ranges from `MarkdownStreamCollector` so the streaming controller can render and scan the collector's source directly.
- Transfer the complete source out of the collector during finalization, preserving the final unterminated line while removing the controller's duplicate source buffer.
- Cover finalization of an empty collector and update streaming tests to validate the collector-backed source.
GitOrigin-RevId: 0aca912c53080267a2d12ad397e548641171942a
## What changed
Make `thread_to_transcript_cells` consume its `Thread` so transcript rendering can
move owned turn items, message content, IDs, and plan text into history cells
instead of cloning them.
GitOrigin-RevId: 80200ba8928a3ea0e91cbff8a13dd00e21432426
## Why
Clients that use full-history resume or request full items in turn pages should
work consistently across legacy and paginated threads.
## What changed
- Materialize complete turns and items from the paginated projection for
`thread/resume` and `thread/turns/list` when requested.
- Support `initialTurnsPage` during paginated resume, including merging a live
active turn while preserving the requested page size and cursors.
- Keep metadata-only resume behavior and backwards cursors available through
`excludeTurns: true`.
## Testing
- Extend app-server coverage for full paginated history, full item views, and
initial resume pages on running threads.
GitOrigin-RevId: e340f44d631ce135895c95d7e1baa7bfecd86e71
## What changed
- Add an optional `initialItems` field to `thread/realtime/start` for seeding
realtime V3 session history with `user`, `developer`, and `assistant` text.
- Encode the items in Frameless Bidi session bootstrap payloads for websocket
and WebRTC transports while preserving existing payloads when the list is
omitted or empty.
- Reject non-empty initial items for V1 and V2, more than 128 items, any item
over 8,192 estimated tokens, or a combined total over 8,192 estimated tokens.
## Testing
- Cover protocol serialization, app-server forwarding, websocket and WebRTC
payloads, empty-list compatibility, version checks, and size limits.
GitOrigin-RevId: 09af367f9a07543e3f8d59b7fa5387f932dc5a6a
## What changed
- Redraw assistant and plan stream tails only when a completed line changes the visible tail.
- Cache the first reasoning header and update the status indicator only when its visible state changes, while restoring the cached header if the indicator is recreated.
- Keep regular commit ticks able to clear stale stream tails.
## Testing
- Add coverage for unchanged partial deltas, changed newline-delimited tails, reasoning-header redraws, recreated status indicators, stale plan tails, and history-line draw scheduling.
GitOrigin-RevId: 9016175f97ef2db2edc2fd5ba13a4d731dc2d98c
## What changed
Update normal-mode reasoning shortcuts to emit only an
`UpdateReasoningEffort` event instead of reapplying the current model alongside
the new effort.
Extend the shortcut tests to verify that both increasing and decreasing
reasoning effort leave the model unchanged.
GitOrigin-RevId: cf5206a3a8e0a0bf66ecc2d0bfcc1ba44c98fead
## Why
Streaming TUI responses repeatedly rendered the entire accumulated Markdown source for each committed delta, including blocks whose output could no longer change.
## What changed
- Retain rendered output for completed top-level Markdown blocks and rerender only the final mutable block as new source arrives.
- Track block boundaries during the existing Markdown parser pass and map them through table-fence normalization.
- Preserve canonical full rendering when source-wide state may affect earlier output, including reference link definitions and inline visualizations, and when the width or render mode changes.
- Append raw-mode lines directly while preserving blank lines.
## Testing
Added coverage that compares incremental output with full rendering across paragraphs, headings, lists, block quotes, code fences, tables, HTML blocks, links, visualizations, render-mode changes, and normalized table fences.
GitOrigin-RevId: 748171c4ed58923329b59c48ea3c2afa4819ec88
## Why
The thread inventory check compared state database rows only with plain
`.jsonl` rollout files. Once a rollout was compressed to `.jsonl.zst`, the
check could report its canonical database row as stale and omit the rollout
from parity results.
## What changed
- Scan completed compressed rollouts and match them to database rows using
their canonical `.jsonl` paths.
- Prefer a plain rollout when both plain and compressed siblings exist, and
ignore compression temporary files.
- Keep unreadable compressed rollouts in the set of existing paths so they
produce scan errors without also producing misleading stale-row reports.
- Use canonical paths when deriving legacy thread IDs and archived status.
## Testing
Added coverage for active and archived compressed rollouts, plain/compressed
siblings, metadata and legacy filename IDs, corrupt compressed data, and
compression temporary files.
GitOrigin-RevId: 2461376432194a4062beedbe875aa7002dd2049f
## What changed
- Add `audio` to the model input modalities exposed by the protocol and generated app-server schemas.
- Preserve audio in prompts for models that advertise audio input, and replace historical audio with an omission marker for models that do not.
## Testing
- Cover prompt normalization with and without audio support.
- Extend the model-switching integration test to verify that switching from a multimodal model to a text-only model strips prior image and audio content.
GitOrigin-RevId: c18e47ad602720216303ff9abb5bca4d508391ee
## What changed
- Add structured `turn_id`, `retries`, `max_retries`, and `sampling_error` fields to sampling-stream retry warnings.
- Add a focused test that captures the warning and verifies its retry and error context.
GitOrigin-RevId: dea868875d162b3f97b3c8a256359278f7267c1c
## What changed
- Set the bundled GPT-5.6 model variants' context windows to 272,000 tokens.
- Refresh model instructions and message configuration.
- Record reasoning-summary support and update skills, permissions, and auto-review metadata across the model catalog.
GitOrigin-RevId: 8be55124bf50af14756a174033a5cb362f4db714
## What changed
- Add `tui.resume_cwd` with `current` and `session` modes for resume and fork flows.
- Let users persist either mode directly from the working-directory prompt, while preserving one-time choices when no preference is configured.
- Apply the preference consistently during startup and in-app resume, honor explicit `--cd` overrides, and reject unsupported or unavailable directory choices with a clear error.
## Testing
- Cover configuration parsing and persistence, prompt behavior, startup and in-app flows, session metadata fallback, and remote workspace constraints.
GitOrigin-RevId: 7bf144c4b8c55bdb868cc8a71caf397c7740451a
## What changed
- Model permission instructions as a world-state section keyed by a stable hash of their rendered developer message.
- Re-emit permission context when its model-visible contents change or the retained fragment is missing, while avoiding duplicates when matching instructions already exist in history, including bundled developer messages.
- Normalize CRLF line endings when hashing world-state fragments so equivalent content produces the same snapshot.
## Testing
- Add snapshot coverage for unchanged, changed, absent, and unknown permission state.
- Cover bundled retained permissions and restored world-state baselines during rollout reconstruction.
GitOrigin-RevId: 7d8d212460c1690ca617859f66dcd825987f1e23
## What changed
- Add `SqliteConfig` as the shared entry point for read-write and read-only SQLite pools.
- Apply consistent WAL, synchronization, auto-vacuum, busy-timeout, logging, and pool-size settings to writable Codex databases.
- Route state runtime, audit, CLI, and test database connections through the shared configuration.
## Testing
- Run migration tests against temporary on-disk databases opened through `SqliteConfig`, including the concurrent-writer repair case.
GitOrigin-RevId: e3946b98bde04c47574532ac8b1a7bb2b03edd97
## Why
Audio variants were available in the user-input protocol but were replaced with unsupported-input placeholders instead of being sent to the model.
## What changed
- Serialize audio data URLs as `input_audio` content and convert local `wav`, `mp3`, `m4a`, `webm`, and `ogg` files to labeled data URLs.
- Validate and canonicalize base64 audio before requests, enforce the 50 MiB input limit, and replace invalid, unsupported, or oversized audio with explanatory text.
- Preserve audio attachments when mapping response items back to user-message events and document the app-server input variants.
## Testing
- Add unit coverage for local-file conversion, data URL validation, size and format errors, event mapping, and attachment extraction.
- Add client tests that verify data URL and local audio payloads sent to the Responses API.
GitOrigin-RevId: f72cd6b6e43ab12757eeb47621b1d670594ac7d9
## What changed
- Add `HistoryPosition` to identify a source thread and an exclusive rollout
prefix by ordinal and JSONL byte offset.
- Add optional `history_base` metadata to `SessionMeta` so a thread can record
an inherited prefix of another paginated rollout.
- Default missing `history_base` metadata to `None` and omit it when unset to
preserve compatibility with existing rollout metadata.
## Testing
- Verify that legacy session metadata without `history_base` deserializes with
no inherited history position.
GitOrigin-RevId: 3b2b07a2dfee793d3b37b0a60529f856f167dbc1
## What changed
- Exclude remote and local audio inputs from thread-history searchable text.
- Add a `unit_test_args` option to `codex_rust_crate` and forward it to the
generated unit-test wrapper.
GitOrigin-RevId: f0aeb7f811163c3c80aa6f8ef4104650e698347c
## Why
Windows hook commands whose executable paths contain spaces fail when their
outer quotes are escaped during argument construction.
## What changed
- Pass hook command strings as raw arguments to the default Windows shell.
- Do the same for configured shells that use the case-insensitive `/c` flag,
while retaining normal argument handling for other shells.
## Testing
Add a Windows regression test that runs a quoted `.cmd` hook from a directory
with spaces through both the default shell and an explicit `COMSPEC /c` shell.
GitOrigin-RevId: 0e7ce44203e01d3823daaaec750c2aeadfcd34b7
