## What changed
- Tell the `spawn_agent` tool to set `model` only when the user explicitly
requests a different model.
- Update the tool-description test to enforce the stricter guidance.
GitOrigin-RevId: ed46bcb544876e408896e0d8c54292192369951c
## Why
Model settings can change between steps in the same turn. Token-budget defaults,
context-window limits, and model-visible guidance need to stay aligned with the
model captured for each step.
## What changed
- Preserve the turn's original token-budget preferences and resolve model-owned
defaults when each `StepContext` is created.
- Use the step's model to determine context-window availability and token-budget
guidance, while keeping explicit user settings unchanged.
- Emit one-time replacement or removal notices when context-window guidance
changes, including compatibility with previously persisted world-state
snapshots.
- Add `ModelInfo::usable_context_window()` to distinguish reserved-headroom
capacity from the resolved context window and auto-compaction limit.
## Testing
- Cover mid-turn model switches with model defaults, explicit settings, config
reloads, missing context windows, and missing destination guidance.
- Cover unchanged, replaced, removed, blank, and legacy guidance transitions.
GitOrigin-RevId: 91100a9f3625bef8a79ecd158eb028051c309eee
## Why
Reviewing a shortened `write_stdin` action while sending the complete input could allow unreviewed bytes to reach an escalated terminal.
## What changed
- Require the fully formatted action and approval reason to fit within 8,000 bytes.
- Reject truncated or oversized actions before requesting approval or writing any bytes to the terminal.
- Document the reviewed stdin size limit in the app-server protocol.
## Testing
Add an integration test that uses JSON escaping to push a formatted action over the limit and verifies that it is neither offered for approval nor executed, while a subsequent valid write still succeeds.
GitOrigin-RevId: f6c96a78a65a136366c8119a7d242dfc2ec05fe6
## What changed
- Lower the default `max_tool_call_lag` from three tool calls to two, causing
older async risk scores to fall back to strict review sooner.
- Update the async scorer integration test to verify score expiration using the
default lag instead of a test-specific override.
GitOrigin-RevId: a07cae3634428a1e64745674eced92fb770f441a
## Why
Guardian classification must not proceed after silently dropping a parent
compaction that cannot fit within its configured size limit.
## What changed
- Distinguish an absent or unusable parent compaction from serialization and
size-limit failures.
- Record a fail-closed score and failed classification when the latest encrypted
parent compaction cannot be serialized or exceeds the complete-item byte
budget.
- Preserve omission of compactions with missing or empty encrypted content
without falling back to older context.
## Testing
Cover compactions at the exact byte limit, one byte over it, and oversized
passthrough metadata.
GitOrigin-RevId: 8e607c88f10003cdfab273963bc73c848b09c821
## What changed
- Move bounded planned-action JSON rendering from the Guardian V2 extension implementation into a dedicated `async_scorer::action` module.
- Keep the structural size-limit tests alongside the extracted implementation.
GitOrigin-RevId: 9292b164588ba0119b4c5ff81056bf7416352d69
## What changed
- Store per-turn trusted skill paths directly in a `BTreeSet` instead of a
mutex-protected set.
- Mutably record paths and consume the collection when producing the final
ordered path list.
- Strengthen the bounded-deduplication test to verify the exact collected paths.
GitOrigin-RevId: 69e87fc7783738d85ed204f18a3968d0837c3693
## What changed
Represent completed and superseded Guardian V2 classifications with a dedicated
`ClassificationOutcome` enum. Map the typed outcome to the existing metrics
status and emit truncation metrics only for scored classifications.
GitOrigin-RevId: b00d345cb0162ed3fc7f53632630b631f18820e7
## Why
Large or minified diffs can require substantial work to allocate wrapped rows and syntax-highlighted spans in the inline patch view.
## What changed
- Limit inline patch previews to 12 rendered rows across all changed files, while retaining file summaries and directing users to the transcript when content is omitted.
- Preserve complete diff content in transcript and raw views.
- Bound preview source scanning to 64 KiB so zero-width content cannot bypass the row budget.
## Testing
Add coverage for added, deleted, updated, renamed, minified, narrow-width, wide-character, combining-character, and multi-file diffs, including preservation of complete transcript and raw output.
GitOrigin-RevId: 1899129ab548771c29d226ff624549573fb2f688
## Why
Guardian reviews for delegated workers need to recognize skills explicitly
invoked by the user on the root turn.
## What changed
- Record verified user-owned skill paths as bounded, turn-matched Guardian
evidence.
- Include trusted paths from the current worker and its root snapshot when
building review context.
- Exclude skill trust from later root turns so stale authorization is not
inherited.
## Testing
- Add an app-server lifecycle test covering inheritance of a root-invoked
skill by a delegated worker and its removal on the next root turn.
GitOrigin-RevId: aa28f485edb7a447e51d51de8dc89b959fd63d40
## Why
Plugin MCP trust decisions must describe the exact host-discovered server
registration. Looking up a plugin again by ID can resolve a different root.
## What changed
- Retain the host plugin root in MCP catalog attribution and connection identity.
- Reconnect an MCP server when its attributed plugin root changes.
- Pass the retained root through tool lifecycle attribution and use it directly
when building trusted tool context.
## Testing
Add coverage for catalog identity, connection reconciliation, lifecycle
attribution, and rejecting a different root associated with the same plugin ID.
GitOrigin-RevId: bc92743dd40ab44065a07c3ea972b4956ef8351f
## What changed
Define a shared 30-second timeout for Guardian V2 async tests and use it
for classifier requests, score updates, and authentication refresh waits.
GitOrigin-RevId: fa0e63e5e4c2b9ba0e3a09f0c8758886a867e546
## What changed
- Record classified risk levels in `codex.guardian_v2.classification.risk`.
- Record fast approval outcomes and their reasons in
`codex.guardian_v2.fast_decision`, including low-risk approvals and deferred
decisions caused by missing, stale, failed, out-of-scope, or elevated-risk
scores.
- Cover the new metric labels across approval and failure paths.
GitOrigin-RevId: e180054e0b3796e479a706157dd9ea7c9f03c001
## What changed
- Recognize `codex_sensitive_action: true` on MCP approval elicitations.
- Route marked actions to the synchronous Guardian reviewer instead of extension fast approval. Absent or false values preserve the existing path.
- Cover ordinary and strict auto-review configurations, including marked, unmarked, and explicitly false metadata.
GitOrigin-RevId: dce13d1696568ca81c8d2b08a7ef0d5f13e155bf
## What changed
- Parse optional `usage_metadata.amount` values from Responses API completion events without converting their string representation.
- Propagate the metadata through SSE and WebSocket streams, regular turns, and remote compaction.
- Add `usageMetadata` to the app-server `rawResponse/completed` notification and its generated schemas.
## Testing
- Cover missing, null, zero, and high-precision amounts, including completion events emitted during compaction.
GitOrigin-RevId: b16d81e8350eab0dc7ff613d0dc9dbed73041713
## What changed
- Add optional Browser Use and Computer Use confirmation-policy Markdown to model catalog messages.
- Send the configured documents verbatim in `openai/confirmation_policies` metadata for `node_repl` and `cua_repl` tool calls. Send an empty object when the issuing model has no policies so runtime defaults are cleared.
- Use the issuing step's model snapshot across approval waits, and omit the metadata for other MCP servers and Guardian sessions.
## Testing
- Cover policy serialization, configuration overrides, model changes, approval waits, partial or empty policies, eligible server filtering, and Guardian exclusion.
GitOrigin-RevId: 038c4c262a31fc71986e4a2a947fe9bcbd407acc
## What changed
Expand the `send_user_message_async` tool description to:
- identify questions, blockers, significant findings, and in-progress replies as
messages that may need immediate user attention;
- distinguish those messages from routine progress updates that belong in
commentary;
- clarify that sending a message neither ends the turn nor waits for a reply;
and
- encourage formatting questions so they are easy to notice and answer.
GitOrigin-RevId: 004ba7fd77b2e225a4baa2ab69d08660a2cf73d7
## What changed
- Serialize each history and notes request's output truncation policy into the
`x-openai-tool-output-truncation-policy` header.
- Forward the invoking tool call's policy for tool requests and use the thread
hint byte limit for context-contributor requests.
GitOrigin-RevId: 9d4e61480397b325efdb033861893e88c708de3b
## Why
Executed-tool metadata for a Code Mode cell can span its `exec` and `wait`
outputs. Consumers need to know whether that metadata contains the cell's full
tool call inventory or only a partial record.
## What changed
- Associate recorded tool calls with the originating Code Mode cell across
`exec` and `wait` outputs.
- Add a host-owned `tool_calls_complete` marker when recording finishes without
dropped or truncated calls. The marker describes inventory completeness, not
tool success.
- Preserve the cell metadata through replay and pruning, and clear the
completeness marker when prompt budgeting makes the record incomplete.
## Testing
Add coverage for multi-wait cells, retries, interruptions, recording limits,
argument truncation, prompt budgeting, and rejection of input-forged metadata.
GitOrigin-RevId: 377014edec06aab42aadab78b8b5dccc0a1c83ba
## What changed
- Add bundled proactivity and follow-up guidance when `ReasoningEffort::Persistent` is selected.
- Allow model metadata to override or disable the guidance with `persistent_instructions`.
- Track the instructions as world state so effort and model changes replace or retire stale guidance without duplicating unchanged context.
- Tailor approval guidance to `send_user_message_async` availability, rebuild it for forked agents and rolled-back history, and exclude Guardian sessions.
## Testing
- Cover default, overridden, disabled, replaced, and retired instructions.
- Cover model changes, history transitions, agent forks, Guardian sessions, and asynchronous-message tool availability.
GitOrigin-RevId: 78e05d0335a70b385bd069b45edcd4ba570cef91
## Why
Delegated prompts should retain the authority of the TUI tool that sent them instead of being recorded as user input.
## What changed
- Start delegated `create_thread` and `send_message_to_thread` turns with a namespaced tool output and an empty user input list.
- Recognize delegated outputs from trusted Codex namespaces when building activity summaries.
- Render replayed delegation outputs in history and transcripts with their source task attribution, without adding them to composer history.
## Testing
- Cover turn request encoding, namespace filtering, activity summaries, and replayed history/transcript rendering.
GitOrigin-RevId: aeb2f5c8ad2f2a898c80e8fc791ed879a0ab655d
## What changed
- Mark history and notes search queries, appended note text, and replacement note text as encrypted in their tool schemas.
- Send `x-openai-encrypted-tool-arguments: true` for the corresponding backend routes without changing the JSON request body.
## Testing
- Cover encrypted schema fields and backend headers for history search, notes search, append, and write calls.
- Verify unrelated history and notes requests do not receive the encrypted-arguments header.
GitOrigin-RevId: 58263cff832c979b436ddb4013b5c27218aca678
## Why
Trusted Guardian reviewer sessions can emit events without an app-server listener, leaving their turns and tool usage absent from analytics.
## What changed
- Translate Guardian session lifecycle and canonical tool item events into analytics notifications while excluding messages, reasoning, and review content.
- Preserve Guardian lineage during prewarming even when inherited client metadata is not yet available, without emitting an incomplete thread initialization event.
- Limit direct session tracking to trusted Guardian children so resumed threads that have an app-server listener do not report duplicate events.
## Testing
- Cover completed, failed, and interrupted Guardian turns, tool counts and timing, lineage, content exclusion, prewarmed lineage, and resumed-thread deduplication.
GitOrigin-RevId: 70ace5f7ed30a7e3b6a9d6097c8b2a6a326dc4f7
## What changed
- Add callback lifetimes to extension `ToolCall`, `ToolEnvironment`, turn-input context, and skill-read request types.
- Require extension tool executors to handle calls for any invocation lifetime and tie their returned futures to that lifetime.
- Update built-in extensions, adapters, and tests to use the lifetime-scoped APIs without retaining host-owned environment capabilities.
GitOrigin-RevId: aca9ce3a1b6870df550bc84ec9308cc65533f161
## What changed
- Inject W3C `traceparent` metadata into code-mode session and execution requests.
- Carry each execution's trace context on streamed tool callbacks so callback and nested-tool spans remain connected across the gRPC boundary.
- Preserve the relevant spans when execution, callback, and dispatch work moves into spawned tasks.
GitOrigin-RevId: 6482963cb9b2e2f0ea27f1345bba208b70a80d0b
## Why
Repeated skill locator roots can make catalog prompts larger even when the
catalog fits within its metadata budget.
## What changed
Evaluate aliased catalogs regardless of budget pressure and select them when
they preserve skill inclusion and description content while reducing prompt
size. Apply the same selection to combined host, executor, and orchestrator
catalogs.
## Testing
Add coverage for alias selection in full host-only catalogs and update skill,
symlink, and orchestrator resource tests to expect shortened locators and their
root mappings.
GitOrigin-RevId: ccedd3f3f6c7efaa1e5177a2d8c3d81d59239f52
## Why
Guardian treated all skill instructions as untrusted, so it could not use the
invocation of a user-owned skill as authorization evidence.
## What changed
- Record explicit and implicit skill invocations through extension contributors.
- Send Guardian a bounded, deduplicated list of canonical skill paths only when
they resolve under the user's Codex or `.agents` skill directories.
- Keep repository skills and symlinks that escape trusted roots untrusted, and
send only verified paths rather than skill contents to the classifier.
- Avoid recording host skill prompts that were superseded by core skill
injection.
## Testing
- Added unit coverage for trusted roots, symlink escapes, deduplication, and
size limits.
- Added integration coverage showing that Guardian trusts invoked user skills
while rejecting a forged repository skill.
GitOrigin-RevId: 1cc0be230f7e6649110201c23c3de8f26447ff36
## What changed
- Fetch ChatGPT account access and attach `cyber_trusted_access` under
`openai/entitlementContext` when an installed or selected plugin explicitly
requests it from a local, read-only stdio tool with no arguments.
- Reject caller-supplied entitlement context on direct MCP calls, and fall back
to an `unknown` status when access cannot be verified or the account changes
during the lookup.
- Count entitlement lookup time against the MCP tool-call timeout.
## Testing
- Cover eligible calls plus unowned, remote, HTTP, mutable, argument-bearing,
API-key, undeclared, direct, and account-switch cases in core and app-server
integration tests.
GitOrigin-RevId: 303b61585ef4530276c373d914a2d0ccef1f4ac2
## What changed
- Add an optional `toolOutput` to `turn/start` for starting or steering a turn with a named function-call output instead of user input.
- Emit standalone outputs as `functionCallOutput` thread items, persist them in durable history, and include them in resumed threads.
- Validate that tool outputs have a name, are not combined with nonempty `input`, satisfy the text-size limit, and use supported image URLs.
## Testing
- Cover standalone tool-output notifications, model input, and resumed history in both legacy and paginated history modes.
- Cover the text-size limit for structured tool output.
GitOrigin-RevId: a1eeec7b9b7de67b1a1c5e829a54552b85ec118b
## Why
Filesystem policies can describe paths using a convention that differs from the
host running Codex. Native path comparisons can therefore mis-handle cases such
as case-variant Windows paths or ambiguous encoded components.
## What changed
- Resolve policy entries and special roots as `PathUri` values using the
executor's path convention.
- Use validated URI components for containment, overlap, and precedence, and
fail closed when component boundaries are ambiguous.
- Restrict relative joins to descendants and apply the same matching rules to
protected metadata paths and permission-profile intersections.
## Testing
Added coverage for Windows case variants, encoded and opaque paths, repeated
separators, descendant joins, special roots, metadata protection, and preserved
deny entries.
GitOrigin-RevId: fb09d44d11df25faaac806fe00457e6f6b0d8596
## Why
Linux managed networking routed proxy connections through filesystem-backed Unix sockets, requiring an extra readable sandbox path and stale socket cleanup.
## What changed
- Transfer loopback TCP listeners from the sandbox namespace to host bridge processes over anonymous Unix socket pairs.
- Validate transferred descriptors, keep bootstrap channels private to each sandbox launch, and close them before running untrusted commands.
- Tie proxy bridge lifetime to the sandbox so cancellation closes active upstream connections.
## Testing
- Cover descriptor validation and interrupted handoffs.
- Verify concurrent sandboxes keep proxy endpoints isolated and do not inherit privileged sockets.
- Exercise managed networking end to end through `app-server`, confirming proxied access succeeds while direct host access remains blocked.
GitOrigin-RevId: 6561e09c83b927c604951bf2aa00ff532d179da5
## What changed
- Promote `compaction_image_budget` to stable and enable it by default.
- Charge retained images against the remote compaction context budget unless the feature is explicitly disabled, trimming older images as needed.
## Testing
- Update remote compaction coverage for the default, explicitly enabled, and explicitly disabled behavior.
GitOrigin-RevId: 0f715347cefc33b814bdcfd9b430ef453d3bd6df
## Why
Executor plugin manifests are unsigned, so cleanup hooks must remain limited to
explicitly trusted plugin identities and MCP targets.
## What changed
- Allow the bundled Browser, Chrome, Chrome Dev, and Chrome Internal plugins to
run the existing `Stop` hook for `node_repl.turn_ended`.
- Continue allowing the bundled Computer Use plugin and rejecting unlisted or
lookalike marketplace identities.
## Testing
- Extend manifest-filtering coverage for unlisted bundled plugins and marketplace
name variants.
GitOrigin-RevId: 1ad5d679a1530994df5a9628c2117ce509fec9ad
## What changed
- Add `TrustedAccessContext` to fetch account-bound cyber verified-access grants and attach them as host-owned `openai/entitlementContext` metadata.
- Replace caller-supplied entitlement metadata and return an `unknown` status when authentication, identity consistency, response validation, size limits, or the lookup deadline cannot be verified.
- Add `HttpResponseBodyStream::from_chunks` for lightweight in-memory streaming clients.
## Testing
- Cover grant mapping, unsupported authentication, account and workspace changes, malformed or oversized responses, duplicate programs, and lookup timeouts.
GitOrigin-RevId: 343b6a6608c98c45a34939ef507c2183516a11c1
## What changed
- Allow `start_or_steer_turn` to accept named `function_call_output` items without a `call_id`, starting a turn when idle or steering the active turn.
- Preserve standalone outputs as pending input, assign response item IDs, and record them in conversation history without treating them as user prompts.
## Testing
- Cover starting a turn with a standalone output and steering an active turn with one.
- Verify passive response items do not signal pending steering activity.
GitOrigin-RevId: e32b292106b3c5a5f03577b8ebf67d2d7dee4e5d
## What changed
- Add the zero-based `window_number` to Responses turn metadata and include it in prewarm requests.
- Persist `forked_from_ordinal_exclusive` separately from the physical history base so fork lineage remains accurate after reverts and cold resumes.
- Report context-inheriting subagents through `parent_thread_id` without also emitting fork lineage.
- Reserve the new metadata keys while accepting and filtering previously valid configured values so Codex-owned values take precedence.
## Testing
- Cover window numbering across compaction, resume, and fork operations.
- Cover fork cutoff persistence across direct forks, legacy rollouts, reverts into inherited history, and cold resumes.
GitOrigin-RevId: 288f6cd632254814c1f166668b33828082d799a1
## Why
Opening Guardian's initial WebSocket connections can be delayed, but thread startup and resume do not need to wait for those connections.
## What changed
- Install the Guardian sampler and related thread state before opening its initial connections.
- Prewarm the sampler's WebSocket pool in a background task while retaining the existing on-demand connection behavior.
## Testing
- Verify extension startup returns before a delayed WebSocket handshake completes, then warms the full initial connection pool.
- Verify resuming a thread likewise returns before Guardian's delayed handshake completes.
GitOrigin-RevId: 58c91cf045b223f917c67d7e8dc82eac529db4ce
## What changed
- Return the number of directories flagged by successful Windows sandbox world-writable scans.
- Record that count in the `codex.windows_sandbox.world_writable_scan_flagged_directories` histogram for startup and warning-triggered scans.
- Tag each measurement with a `success` or `error` result, using a count of zero when the scan fails.
GitOrigin-RevId: 076160f36b1d62fa737f4b2d0318774e6c44a4b1
## What changed
- Add a bounded developer context fragment identifying the MCP server or connector and the user-owned configuration that declared it.
- Emit the fragment only when the effective entry matches the user configuration or an active plugin declaration resolves inside the Codex home directory.
- Keep tool descriptions, outputs, and unrelated tools untrusted, and reject unsupported sources or paths that escape through symlinks.
## Testing
- Cover user-configured servers and connectors, plugin-provided capabilities, token truncation, symlink escapes, and app-server request integration.
GitOrigin-RevId: 0bfe2a2f3a48334d1d5faad692b5d36452febb68
## What changed
Point the stable exec-server compatibility test at the pinned Codex 0.150.0
Linux x86_64 release and update the release archive checksum.
GitOrigin-RevId: 6178a1170faffe3dc70c9cfbfcbe3439b201096f
## What changed
- Add the `write_stdin_approval` feature flag, disabled by default, to require a fresh approval before sending non-empty input to an escalated unified-exec terminal.
- Route these reviews through hooks, Guardian, app-server, and the TUI as `writeStdin` approvals while keeping the parent command item unchanged.
- Preserve the terminal environment, launch directory, and escalation state across turns, and revalidate the process identity after approval before writing input.
## Testing
- Cover approval routing, policy decisions, process reuse, terminal identity preservation, app-server events, analytics, and TUI rendering.
GitOrigin-RevId: 4ba29eaae6208e934737ba078c96e589c7c2164d
## What changed
- Add optional `McpToolContext` metadata to `ToolStartInput`, exposing the
model-visible MCP tool details and its source classification without exposing
the executable client.
- Classify MCP calls as connectors, configured servers, plugin servers,
executor-selected plugins, or other registrations based on the prepared call.
- Prepare each MCP call before notifying tool lifecycle contributors and reuse
that same call for execution so the callback describes the call that runs.
## Testing
- Cover host-owned connector calls and extension-owned Apps server calls,
including their distinct provenance and executed tool names.
GitOrigin-RevId: efd23f511b1045ffdd96349d621ad62365569b2b
## Why
Models that require automatic review previously skipped Guardian v2 risk scoring
entirely, even when Guardian was limited to computer-use tools. That scope cannot
use a low-risk result to approve unrelated tools, so the blanket skip is
unnecessary.
## What changed
- Retain Guardian v2 risk scoring for required-review models in
`ComputerUseOnly` scope while continuing to skip it in standard scope.
- Preserve strict automatic approval review for Node REPL-backed tools, including
when classification fails.
## Testing
Added coverage for low-risk, high-risk, and invalid classifications across the
Node REPL and computer-use REPL paths, plus an unrelated MCP tool.
GitOrigin-RevId: ee38fabf82e196df0ae13b4216b5892be9b799cf
## What changed
Remove `minimum`, `maximum`, and `maxLength` from the supported tool input
schema representation. Schema parsing now drops these bounds instead of
including them in generated tool declarations, including declarations for
reserved history and notes tools.
GitOrigin-RevId: b7c7733651e65d38cc3d0cef2efa127ab3f8a32f
## What changed
- Add a synchronous reviewer prompt builder that combines root authorization,
trusted user answers, bounded conversation history, parent environment and
permission context, retained REPL evidence, and the proposed action.
- Select text or image REPL evidence from Guardian feature and transcript
settings while respecting the reviewer model's supported modalities and
shared image limits.
- Render network access requests with trigger-specific guidance and bound
approval reasons and nested action strings before including them.
## Testing
- Add a prompt test covering root authorization, untrusted transcript framing,
retry reasons, denied-read restrictions, and action serialization.
GitOrigin-RevId: d1cf886c2e30f7abbf94cce977cef14439ef3f2e
## Why
Responses Lite rebuilds its tools and base-instruction prefix for each request. Stable item identities let follow-up WebSocket requests recognize that unchanged prefix and send only incremental input.
## What changed
- Derive deterministic IDs for additional-tools and base-instruction items from the thread ID and each item's serialized payload.
- Preserve IDs when rebuilding an unchanged request or resuming a session, while changing them when the thread or payload changes.
## Testing
- Cover ID stability and payload/thread sensitivity in request construction.
- Verify resumed Responses Lite sessions reuse prefix IDs and WebSocket follow-ups use `previous_response_id` with only new input items.
GitOrigin-RevId: 3c8548b96979d7578865b0ccc51c147926823478
## Why
Filesystem helpers should not inherit access to system scratch directories beyond the paths granted by their filesystem policy, while ordinary processes still need scratch access for compatibility.
## What changed
- Move the `/tmp` and `/var/tmp` read/write grants, including their `/private` aliases, from the shared platform defaults into the process-only Seatbelt defaults.
- Keep process access to `/Applications` alongside the scratch-directory grants.
## Testing
Add a macOS Seatbelt test that verifies the generated policies and, when nested Seatbelt execution is available, confirms process scratch access, helper denial, and helper access to an approved project path.
GitOrigin-RevId: 26d83f09c131c1f1d000163b2f8929f601749719
## What changed
- Add `gg` and `G` motions to jump to the first and last buffer lines.
- Support the motions with delete, change, and yank operators, including dot-repeat for edits.
- Expose normal-mode and operator-motion bindings in the configurable keymap while preserving conflicting user bindings.
## Testing
- Cover buffer jumps, operator combinations, repeat behavior, chord routing, and custom remapping.
GitOrigin-RevId: 24a9178cf7964053aaf9a8cd268c5434dda0778e
