 3. First check whether the PR is now merged or otherwise closed; if so, report that terminal state and stop polling immediately.

-7. Retry failed checks only when `retry_failed_checks` is present and you are not about to replace the current SHA with a review/CI fix commit.
-8. If you pushed a commit or triggered a rerun, report the action briefly and continue polling (do not stop).
-9. After a review-fix push, proactively restart continuous monitoring (`--watch`) in the same turn unless a strict stop condition has already been reached.

+6. For each surfaced review item from another author, either reply once with an explanation if it is non-actionable or patch/commit/push and then resolve it if it is actionable. If a later snapshot surfaces your own reply, treat it as informational and continue without responding again.

+13. Otherwise sleep according to the polling cadence below and repeat.
 
 When the user explicitly asks to monitor/watch/babysit a PR, prefer `--watch` so polling continues autonomously in one command. Use repeated `--once` snapshots only for debugging, local testing, or when the user explicitly asks for a one-shot check.
 Do not stop to ask the user whether to continue polling; continue autonomously until a strict stop condition is met or the user explicitly interrupts.

+# Workflow Strategy
+
+The workflows in this directory are split so that pull requests get fast, review-friendly signal while `main` still gets the full cross-platform verification pass.
+
+## Pull Requests
+
+- `bazel.yml` is the main pre-merge verification path for Rust code.
+  It runs Bazel `test` and Bazel `clippy` on the supported Bazel targets.
+- `rust-ci.yml` keeps the Cargo-native PR checks intentionally small:
+  - `cargo fmt --check`
+  - `cargo shear`
+  - `argument-comment-lint` on Linux, macOS, and Windows
+  - `tools/argument-comment-lint` package tests when the lint or its workflow wiring changes
+
+The PR workflow still keeps the Linux lint lane on the default-targets-only invocation for now, but the released linter runs on Linux, macOS, and Windows before merge.
+
+## Post-Merge On `main`
+
+- `bazel.yml` also runs on pushes to `main`.
+  This re-verifies the merged Bazel path and helps keep the BuildBuddy caches warm.
+- `rust-ci-full.yml` is the full Cargo-native verification workflow.
+  It keeps the heavier checks off the PR path while still validating them after merge:
+  - the full Cargo `clippy` matrix
+  - the full Cargo `nextest` matrix
+  - release-profile Cargo builds
+  - cross-platform `argument-comment-lint`
+  - Linux remote-env tests
+
+## Rule Of Thumb
+
+- If a build/test/clippy check can be expressed in Bazel, prefer putting the PR-time version in `bazel.yml`.
+- Keep `rust-ci.yml` fast enough that it usually does not dominate PR latency.
+- Reserve `rust-ci-full.yml` for heavyweight Cargo-native coverage that Bazel does not replace yet.

 ### `codex exec` to run Codex programmatically/non-interactively
 
-To run Codex non-interactively, run `codex exec PROMPT` (you can also pass the prompt via `stdin`) and Codex will work on your task until it decides that it is done and exits. Output is printed to the terminal directly. You can set the `RUST_LOG` environment variable to see more about what's going on.
+To run Codex non-interactively, run `codex exec PROMPT` (you can also pass the prompt via `stdin`) and Codex will work on your task until it decides that it is done and exits. If you provide both a prompt argument and piped stdin, Codex appends stdin as a `<stdin>` block after the prompt so patterns like `echo "my output" | codex exec "Summarize this concisely"` work naturally. Output is printed to the terminal directly. You can set the `RUST_LOG` environment variable to see more about what's going on.
 Use `codex exec --ephemeral ...` to run without persisting session rollout files to disk.

 - You may optionally start the tool input with a first-line pragma like `// @exec: {"yield_time_ms": 10000, "max_output_tokens": 1000}`.
 - `yield_time_ms` asks `exec` to yield early after that many milliseconds if the script is still running.
 - `max_output_tokens` sets the token budget for direct `exec` results. By default the result is truncated to 10000 tokens.
-- All nested tools are available on the global `tools` object, for example `await tools.exec_command(...)`. Tool names are exposed as normalized JavaScript identifiers, for example `await tools.mcp__ologs__get_profile(...)`.
-- Tool methods take either string or object as parameter.
-- They return either a structured value or a string based on the description above.
+- When the JS code is fully evaluated, the isolate's lifetime ends and unawaited promises are silently discarded.

 - `exit()`: Immediately ends the current script successfully (like an early return from the top level).

-        Only use `spawn_agent` if and only if the user explicitly asks for sub-agents, delegation, or parallel agent work.
-        Requests for depth, thoroughness, research, investigation, or detailed codebase analysis do not count as permission to spawn.
-        Agent-role guidance below only helps choose which agent to use after spawning is already authorized; it never authorizes spawning by itself.
-        Spawn a sub-agent for a well-scoped task. {return_value_description} This spawn_agent tool provides you access to smaller but more efficient sub-agents. A mini model can solve many tasks faster than the main model. You should follow the rules and guidelines below to use this tool.

-{available_models_description}
-### When to delegate vs. do the subtask yourself
-- First, quickly analyze the overall user task and form a succinct high-level plan. Identify which tasks are immediate blockers on the critical path, and which tasks are sidecar tasks that are needed but can run in parallel without blocking the next local step. As part of that plan, explicitly decide what immediate task you should do locally right now. Do this planning step before delegating to agents so you do not hand off the immediate blocking task to a submodel and then waste time waiting on it.
-- Use the smaller subagent when a subtask is easy enough for it to handle and can run in parallel with your local work. Prefer delegating concrete, bounded sidecar tasks that materially advance the main task without blocking your immediate next local step.
-- Do not delegate urgent blocking work when your immediate next step depends on that result. If the very next action is blocked on that task, the main rollout should usually do it locally to keep the critical path moving.
-- Keep work local when the subtask is too difficult to delegate well and when it is tightly coupled, urgent, or likely to block your immediate next step.
-
-### Designing delegated subtasks
-- Subtasks must be concrete, well-defined, and self-contained.
-- Delegated subtasks must materially advance the main task.
-- Do not duplicate work between the main rollout and delegated subtasks.
-- Avoid issuing multiple delegate calls on the same unresolved thread unless the new delegated task is genuinely different and necessary.
-- Narrow the delegated ask to the concrete output you need next.
-- For coding tasks, prefer delegating concrete code-change worker subtasks over read-only explorer analysis when the subagent can make a bounded patch in a clear write scope.
-- When delegating coding work, instruct the submodel to edit files directly in its forked workspace and list the file paths it changed in the final answer.
-- For code-edit subtasks, decompose work so each delegated task has a disjoint write set.
-
-### After you delegate
-- Call wait_agent very sparingly. Only call wait_agent when you need the result immediately for the next critical-path step and you are blocked until it returns.
-- Do not redo delegated subagent tasks yourself; focus on integrating results or tackling non-overlapping work.
-- While the subagent is running in the background, do meaningful non-overlapping work immediately.
-- Do not repeatedly wait by reflex.
-- When a delegated coding task returns, quickly review the uploaded changes, then integrate or refine them.
-
-### Parallel delegation patterns
-- Run multiple independent information-seeking subtasks in parallel when you have distinct questions that can be answered independently.
-- Split implementation into disjoint codebase slices and spawn multiple agents for them in parallel when the write scopes do not overlap.
-- Delegate verification only when it can run in parallel with ongoing implementation and is likely to catch a concrete risk before final integration.
-- The key is to find opportunities to spawn multiple independent subtasks in parallel within the same round, while ensuring each subtask is well-defined, self-contained, and materially advances the main task."#

-# codex-package-manager
-
-`codex-package-manager` is the shared installer used for versioned runtime bundles and other cached artifacts in `codex-rs`.
-
-It owns the generic parts of package installation:
-
-- current-platform detection
-- manifest and archive fetches
-- checksum and archive-size validation
-- archive extraction for `.zip` and `.tar.gz`
-- staging and promotion into a versioned cache directory
-- cross-process install locking
-
-Package-specific code stays behind the `ManagedPackage` trait.
-
-## Model
-
-The package manager is intentionally small:
-
-1. A `ManagedPackage` implementation describes how to fetch a manifest, choose an archive for a `PackagePlatform`, and load a validated installed package from disk.
-2. `PackageManager::resolve_cached()` returns a cached install for the current platform if `load_installed()` succeeds and the version matches.
-3. `PackageManager::ensure_installed()` acquires a per-install lock, downloads the archive into a staging directory, extracts it, validates the staged package, and promotes it into the cache.
-
-The default cache root is:
-
-```text
-<codex_home>/<default_cache_root_relative>
-```
-
-Callers can override that root with `PackageManagerConfig::with_cache_root(...)`.
-
-## ManagedPackage Contract
-
-The trait is small, but the invariants matter:
-
-- `install_dir()` should be unique per package version and platform. If two versions or two platforms share a directory, promotion and cleanup become unsafe.
-- `load_installed()` must fully validate the installed package, not just deserialize a manifest. `resolve_cached()` trusts a successful load as a valid cache hit.
-- The default `detect_extracted_root()` looks for `manifest.json` at the extraction root or inside a single top-level directory. Override it if your package layout differs.
-- `archive_url()` should be derived from manifest data, not recomputed from unrelated caller state, so manifest selection and download stay aligned.
-
-## Consumer Guidance
-
-- If your feature can install on demand, do not gate feature registration on a preinstalled-cache check alone. `resolve_cached()` only answers "is it already present?" while `ensure_installed()` is the bootstrap path.
-- Keep cache-root overrides inside your manager/config surface. Separate helpers that reconstruct install paths can drift from `PackageManagerConfig`.
-- Prefer surfacing package-specific validation failures from `load_installed()` when debugging. The generic manager treats failed cache loads as cache misses today.
-
-## Security and Extraction Rules
-
-- `.zip` extraction rejects entries that escape the extraction root and preserves Unix executable bits when the archive carries them.
-- `.tar.gz` extraction rejects symlinks, hard links, sparse files, device files, and FIFOs. Only regular files and directories are promoted.
-- The archive SHA-256 is always verified, and `size_bytes` is enforced when present in the manifest.
-
-## Extending It
-
-Typical usage looks like this:
-
-```rust,ignore
-let config = PackageManagerConfig::new(codex_home, MyPackage::new(...));
-let manager = PackageManager::new(config);
-
-let package = manager.ensure_installed().await?;
-```
-
-In practice, most packages should expose their own small wrapper config/manager types over the generic crate so the rest of the codebase does not depend on `ManagedPackage` details directly.

+
+{available_models_description}
+### When to delegate vs. do the subtask yourself
+- First, quickly analyze the overall user task and form a succinct high-level plan. Identify which tasks are immediate blockers on the critical path, and which tasks are sidecar tasks that are needed but can run in parallel without blocking the next local step. As part of that plan, explicitly decide what immediate task you should do locally right now. Do this planning step before delegating to agents so you do not hand off the immediate blocking task to a submodel and then waste time waiting on it.
+- Use the smaller subagent when a subtask is easy enough for it to handle and can run in parallel with your local work. Prefer delegating concrete, bounded sidecar tasks that materially advance the main task without blocking your immediate next local step.
+- Do not delegate urgent blocking work when your immediate next step depends on that result. If the very next action is blocked on that task, the main rollout should usually do it locally to keep the critical path moving.
+- Keep work local when the subtask is too difficult to delegate well and when it is tightly coupled, urgent, or likely to block your immediate next step.
+
+### Designing delegated subtasks
+- Subtasks must be concrete, well-defined, and self-contained.
+- Delegated subtasks must materially advance the main task.
+- Do not duplicate work between the main rollout and delegated subtasks.
+- Avoid issuing multiple delegate calls on the same unresolved thread unless the new delegated task is genuinely different and necessary.
+- Narrow the delegated ask to the concrete output you need next.
+- For coding tasks, prefer delegating concrete code-change worker subtasks over read-only explorer analysis when the subagent can make a bounded patch in a clear write scope.
+- When delegating coding work, instruct the submodel to edit files directly in its forked workspace and list the file paths it changed in the final answer.
+- For code-edit subtasks, decompose work so each delegated task has a disjoint write set.
+
+### After you delegate
+- Call wait_agent very sparingly. Only call wait_agent when you need the result immediately for the next critical-path step and you are blocked until it returns.
+- Do not redo delegated subagent tasks yourself; focus on integrating results or tackling non-overlapping work.
+- While the subagent is running in the background, do meaningful non-overlapping work immediately.
+- Do not repeatedly wait by reflex.
+- When a delegated coding task returns, quickly review the uploaded changes, then integrate or refine them.
+
+### Parallel delegation patterns
+- Run multiple independent information-seeking subtasks in parallel when you have distinct questions that can be answered independently.
+- Split implementation into disjoint codebase slices and spawn multiple agents for them in parallel when the write scopes do not overlap.
+- Delegate verification only when it can run in parallel with ongoing implementation and is likely to catch a concrete risk before final integration.
+- The key is to find opportunities to spawn multiple independent subtasks in parallel within the same round, while ensuring each subtask is well-defined, self-contained, and materially advances the main task."#

This includes `tool_search` (if available) and other means.\n- For connectors/apps that are not installed but needed for an installed plugin, suggest to install them if the task requirements match precisely.\n- For plugins that are not installed but discoverable, only suggest discoverable and installable plugins when the user's intent very explicitly and unambiguously matches that plugin itself.

-//!
-//! On terminals that do not report `KeyEventKind::Release`, space hold-to-talk uses repeated
-//! space key events as "still held" evidence:
-//!
-//! - For pending holds (non-empty composer), if timeout elapses without any repeated space event,
-//!   we treat the key as a normal typed space.
-//! - If repeated space events are seen before timeout, we proceed with hold-to-talk.
-//! - While recording, repeated space events keep the recording alive; if they stop for a short
-//!   window, we stop and transcribe.

-            heard the gulls circling the empty tower, and every dusk she watched ships hesitate at the \
-            mouth of the bay as if listening for a signal that never came. When an old brass key fell \
-            out of a cracked parcel in her workshop, tagged only with the words 'for the lamp room,' \
-            she decided to climb the hill and see what the town had forgotten.";

-            with weather notes, and a lens shrouded beneath salt-stiff canvas. The mechanism was not \
-            broken, only unfinished. Someone had removed the governor spring and hidden it in a false \
-            drawer, along with a letter from the last keeper admitting he had darkened the light on \
-            purpose after smugglers threatened his family. Mara spent the night rebuilding the clockwork \
-            from spare watch parts, her fingers blackened with soot and grease, while a storm gathered \
-            over the water and the harbor bells began to ring.";

-            blind in sheets of rain. Mara wound the mechanism, set the teeth by hand, and watched the \
-            great lens begin to turn in slow, certain arcs. The beam swept across the bay, caught the \
-            whitecaps, and reached the boats just as they were drifting toward the rocks below the \
-            eastern cliffs. In the morning the town square was crowded with wet sailors, angry elders, \
-            and wide-eyed children, but when the oldest captain placed the keeper's log on the fountain \
-            and thanked Mara for relighting the coast, nobody argued. By sunset, Bracken Ferry had a \
-            lighthouse again, and Mara had more clocks to mend than ever because everyone wanted \
-            something in town to keep better time.";

-//! Multi-agent picker navigation and labeling state for the TUI app.
-//!
-//! This module exists to keep the pure parts of multi-agent navigation out of [`crate::app::App`].
-//! It owns the stable spawn-order cache used by the `/agent` picker, keyboard next/previous
-//! navigation, and the contextual footer label for the thread currently being watched.
-//!
-//! Responsibilities here are intentionally narrow:
-//! - remember picker entries and their first-seen order
-//! - answer traversal questions like "what is the next thread?"
-//! - derive user-facing picker/footer text from cached thread metadata
-//!
-//! Responsibilities that stay in `App`:
-//! - discovering threads from the backend
-//! - deciding which thread is currently displayed
-//! - mutating UI state such as switching threads or updating the footer widget
-//!
-//! The key invariant is that traversal follows first-seen spawn order rather than thread-id sort
-//! order. Once a thread id is observed it keeps its place in the cycle even if the entry is later
-//! updated or marked closed.

-/// `App` owns thread lifecycle and UI side effects. This type keeps the pure rules for stable
-/// spawn-order traversal, picker copy, and active-agent labels together and separately testable.

-/// The core invariant is that `order` records first-seen thread ids exactly once, while `threads`
-/// stores the latest metadata for those ids. Mutation is intentionally funneled through `upsert`,
-/// `mark_closed`, and `clear` so those two collections do not drift semantically even if they are

-//! Backtracking and transcript overlay event routing.
-//!
-//! This file owns backtrack mode (Esc/Enter navigation in the transcript overlay) and also
-//! mediates a key rendering boundary for the transcript overlay.
-//!
-//! Overall goal: keep the main chat view and the transcript overlay in sync while allowing
-//! users to "rewind" to an earlier user message. We stage a rollback request, wait for core to
-//! confirm it, then trim the local transcript to the matching history boundary. This avoids UI
-//! state diverging from the agent if a rollback fails or targets a different thread.
-//!
-//! Backtrack operates as a small state machine:
-//! - The first `Esc` in the main view "primes" the feature and captures a base thread id.
-//! - A subsequent `Esc` opens the transcript overlay (`Ctrl+T`) and highlights a user message.
-//! - `Enter` requests a rollback from core and records a `pending_rollback` guard.
-//! - On `EventMsg::ThreadRolledBack`, we either finish an in-flight backtrack request or queue a
-//!   rollback trim so it runs in event order with transcript inserts.
-//!
-//! The transcript overlay (`Ctrl+T`) renders committed transcript cells plus a render-only live
-//! tail derived from the current in-flight `ChatWidget.active_cell`.
-//!
-//! That live tail is kept in sync during `TuiEvent::Draw` handling for `Overlay::Transcript` by
-//! asking `ChatWidget` for an active-cell cache key and transcript lines and by passing them into
-//! `TranscriptOverlay::sync_live_tail`. This preserves the invariant that the overlay reflects
-//! both committed history and in-flight activity without changing flush or coalescing behavior.

-//! Application-level events used to coordinate UI actions.
-//!
-//! `AppEvent` is the internal message bus between UI components and the top-level `App` loop.
-//! Widgets emit events to request actions that must be handled at the app layer (like opening
-//! pickers, persisting configuration, or shutting down the agent), without needing direct access to
-//! `App` internals.
-//!
-//! Exit is modelled explicitly via `AppEvent::Exit(ExitMode)` so callers can request shutdown-first
-//! quits without reaching into the app loop or coupling to shutdown/exit sequencing.

-# TUI bottom pane (state machines)
-
-When changing the paste-burst or chat-composer state machines in this folder, keep the docs in sync:
-
-- Update the relevant module docs (`chat_composer.rs` and/or `paste_burst.rs`) so they remain a
-  readable, top-down explanation of the current behavior.
-- Update the narrative doc `docs/tui-chat-composer.md` whenever behavior/assumptions change (Enter
-  handling, retro-capture, flush/clear rules, `disable_paste_burst`, non-ASCII/IME handling).
-- Keep implementations/docstrings aligned unless a divergence is intentional and documented.
-
-Practical check:
-
-- After edits, sanity-check that docs mention only APIs/behavior that exist in code (especially the
-  Enter/newline paths and `disable_paste_burst` semantics).

-//! The chat composer is the bottom-pane text input state machine.
-//!
-//! It is responsible for:
-//!
-//! - Editing the input buffer (a [`TextArea`]), including placeholder "elements" for attachments.
-//! - Routing keys to the active popup (slash commands, file search, skill/apps mentions).
-//! - Promoting typed slash commands into atomic elements when the command name is completed.
-//! - Handling submit vs newline on Enter.
-//! - Turning raw key streams into explicit paste operations on platforms where terminals
-//!   don't provide reliable bracketed paste (notably Windows).
-//!
-//! # Key Event Routing
-//!
-//! Most key handling goes through [`ChatComposer::handle_key_event`], which dispatches to a
-//! popup-specific handler if a popup is visible and otherwise to
-//! [`ChatComposer::handle_key_event_without_popup`]. After every handled key, we call
-//! [`ChatComposer::sync_popups`] so UI state follows the latest buffer/cursor.
-//!
-//! # History Navigation (↑/↓)
-//!
-//! The Up/Down history path is managed by [`ChatComposerHistory`]. It merges:
-//!
-//! - Persistent cross-session history (text-only; no element ranges or attachments).
-//! - Local in-session history (full text + text elements + local/remote image attachments).
-//!
-//! When recalling a local entry, the composer rehydrates text elements and both attachment kinds
-//! (local image paths + remote image URLs).
-//! When recalling a persistent entry, only the text is restored.
-//! Recalled entries move the cursor to end-of-line so repeated Up/Down presses keep shell-like
-//! history traversal semantics instead of dropping to column 0.
-//!
-//! # Submission and Prompt Expansion
-//!
-//! `Enter` submits immediately. `Tab` requests queuing while a task is running; if no task is
-//! running, `Tab` submits just like Enter so input is never dropped.
-//! `Tab` does not submit when entering a `!` shell command.
-//!
-//! On submit/queue paths, the composer:
-//!
-//! - Expands pending paste placeholders so element ranges align with the final text.
-//! - Trims whitespace and rebases text elements accordingly.
-//! - Expands `/prompts:` custom prompts (named or numeric args), preserving text elements.
-//! - Prunes local attached images so only placeholders that survive expansion are sent.
-//! - Preserves remote image URLs as separate attachments even when text is empty.
-//!
-//! When these paths clear the visible textarea after a successful submit or slash-command
-//! dispatch, they intentionally preserve the textarea kill buffer. That lets users `Ctrl+K` part
-//! of a draft, perform a composer action such as changing reasoning level, and then `Ctrl+Y` the
-//! killed text back into the now-empty draft.
-//!
-//! The numeric auto-submit path used by the slash popup performs the same pending-paste expansion
-//! and attachment pruning, and clears pending paste state on success.
-//! Slash commands with arguments (like `/plan` and `/review`) reuse the same preparation path so
-//! pasted content and text elements are preserved when extracting args.
-//!
-//! # Remote Image Rows (Up/Down/Delete)
-//!
-//! Remote image URLs are rendered as non-editable `[Image #N]` rows above the textarea (inside the
-//! same composer block). These rows represent image attachments rehydrated from app-server/backtrack
-//! history; TUI users can remove them, but cannot type into that row region.
-//!
-//! Keyboard behavior:
-//!
-//! - `Up` at textarea cursor `0` enters remote-row selection at the last remote image.
-//! - `Up`/`Down` move selection between remote rows.
-//! - `Down` on the last row clears selection and returns control to the textarea.
-//! - `Delete`/`Backspace` remove the selected remote image row.
-//!
-//! Placeholder numbering is unified across remote and local images:
-//!
-//! - Remote rows occupy `[Image #1]..[Image #M]`.
-//! - Local placeholders are offset after that range (`[Image #M+1]..`).
-//! - Deleting a remote row relabels local placeholders to keep numbering contiguous.
-//!
-//! # Non-bracketed Paste Bursts
-//!
-//! On some terminals (especially on Windows), pastes arrive as a rapid sequence of
-//! `KeyCode::Char` and `KeyCode::Enter` key events instead of a single paste event.
-//!
-//! To avoid misinterpreting these bursts as real typing (and to prevent transient UI effects like
-//! shortcut overlays toggling on a pasted `?`), we feed "plain" character events into
-//! [`PasteBurst`](super::paste_burst::PasteBurst), which buffers bursts and later flushes them
-//! through [`ChatComposer::handle_paste`].
-//!
-//! The burst detector intentionally treats ASCII and non-ASCII differently:
-//!
-//! - ASCII: we briefly hold the first fast char (flicker suppression) until we know whether the
-//!   stream is paste-like.
-//! - non-ASCII: we do not hold the first char (IME input would feel dropped), but we still allow
-//!   burst detection for actual paste streams.
-//!
-//! The burst detector can also be disabled (`disable_paste_burst`), which bypasses the state
-//! machine and treats the key stream as normal typing. When toggling from enabled → disabled, the
-//! composer flushes/clears any in-flight burst state so it cannot leak into subsequent input.
-//!
-//! For the detailed burst state machine, see `codex-rs/tui/src/bottom_pane/paste_burst.rs`.
-//! For a narrative overview of the combined state machine, see `docs/tui-chat-composer.md`.
-//!
-//! # PasteBurst Integration Points
-//!
-//! The burst detector is consulted in a few specific places:
-//!
-//! - [`ChatComposer::handle_input_basic`]: flushes any due burst first, then intercepts plain char
-//!   input to either buffer it or insert normally.
-//! - [`ChatComposer::handle_non_ascii_char`]: handles the non-ASCII/IME path without holding the
-//!   first char, while still allowing paste detection via retro-capture.
-//! - [`ChatComposer::flush_paste_burst_if_due`]/[`ChatComposer::handle_paste_burst_flush`]: called
-//!   from UI ticks to turn a pending burst into either an explicit paste (`handle_paste`) or a
-//!   normal typed character.
-//!
-//! # Input Disabled Mode
-//!
-//! The composer can be temporarily read-only (`input_enabled = false`). In that mode it ignores
-//! edits and renders a placeholder prompt instead of the editable textarea. This is part of the
-//! overall state machine, since it affects which transitions are even possible from a given UI
-//! state.
-//!
-//! # Voice Hold-To-Talk Without Key Release
-//!
-//! On terminals that do not report `KeyEventKind::Release`, space hold-to-talk uses repeated
-//! space key events as "still held" evidence:
-//!
-//! - For pending holds (non-empty composer), if timeout elapses without any repeated space event,
-//!   we treat the key as a normal typed space.
-//! - If repeated space events are seen before timeout, we proceed with hold-to-talk.
-//! - While recording, repeated space events keep the recording alive; if they stop for a short
-//!   window, we stop and transcribe.

-//! The bottom-pane footer renders transient hints and context indicators.
-//!
-//! The footer is pure rendering: it formats `FooterProps` into `Line`s without mutating any state.
-//! It intentionally does not decide *which* footer content should be shown; that is owned by the
-//! `ChatComposer` (which selects a `FooterMode`) and by higher-level state machines like
-//! `ChatWidget` (which decides when quit/interrupt is allowed).
-//!
-//! Some footer content is time-based rather than event-based, such as the "press again to quit"
-//! hint. The owning widgets schedule redraws so time-based hints can expire even if the UI is
-//! otherwise idle.
-//!
-//! Terminology used in this module:
-//! - "status line" means the configurable contextual row built from `/statusline` items such as
-//!   model, git branch, and context usage.
-//! - "instructional footer" means a row that tells the user what to do next, such as quit
-//!   confirmation, shortcut help, or queue hints.
-//! - "contextual footer" means the footer is free to show ambient context instead of an
-//!   instruction. In that state, the footer may render the configured status line, the active
-//!   agent label, or both combined.
-//!
-//! Single-line collapse overview:
-//! 1. The composer decides the current `FooterMode` and hint flags, then calls
-//!    `single_line_footer_layout` for the base single-line modes.
-//! 2. `single_line_footer_layout` applies the width-based fallback rules:
-//!    (If this description is hard to follow, just try it out by resizing
-//!    your terminal width; these rules were built out of trial and error.)
-//!    - Start with the fullest left-side hint plus the right-side context.
-//!    - When the queue hint is active, prefer keeping that queue hint visible,
-//!      even if it means dropping the right-side context earlier; the queue
-//!      hint may also be shortened before it is removed.
-//!    - When the queue hint is not active but the mode cycle hint is applicable,
-//!      drop "? for shortcuts" before dropping "(shift+tab to cycle)".
-//!    - If "(shift+tab to cycle)" cannot fit, also hide the right-side
-//!      context to avoid too many state transitions in quick succession.
-//!    - Finally, try a mode-only line (with and without context), and fall
-//!      back to no left-side footer if nothing can fit.
-//! 3. When collapse chooses a specific line, callers render it via
-//!    `render_footer_line`. Otherwise, callers render the straightforward
-//!    mode-to-text mapping via `render_footer_from_props`.
-//!
-//! In short: `single_line_footer_layout` chooses *what* best fits, and the two
-//! render helpers choose whether to draw the chosen line or the default
-//! `FooterProps` mapping.

-//! The bottom pane is the interactive footer of the chat UI.
-//!
-//! The pane owns the [`ChatComposer`] (editable prompt input) and a stack of transient
-//! [`BottomPaneView`]s (popups/modals) that temporarily replace the composer for focused
-//! interactions like selection lists.
-//!
-//! Input routing is layered: `BottomPane` decides which local surface receives a key (view vs
-//! composer), while higher-level intent such as "interrupt" or "quit" is decided by the parent
-//! widget (`ChatWidget`). This split matters for Ctrl+C/Ctrl+D: the bottom pane gives the active
-//! view the first chance to consume Ctrl+C (typically to dismiss itself), and `ChatWidget` may
-//! treat an unhandled Ctrl+C as an interrupt or as the first press of a double-press quit
-//! shortcut.
-//!
-//! Some UI is time-based rather than input-based, such as the transient "press again to quit"
-//! hint. The pane schedules redraws so those hints can expire even when the UI is otherwise idle.

-//! Multi-select picker widget for selecting multiple items from a list.
-//!
-//! This module provides a fuzzy-searchable, scrollable picker that allows users
-//! to toggle multiple items on/off. It supports:
-//!
-//! - **Fuzzy search**: Type to filter items by name
-//! - **Toggle selection**: Space to toggle items on/off
-//! - **Reordering**: Optional left/right arrow support to reorder items
-//! - **Live preview**: Optional callback to show a preview of current selections
-//! - **Callbacks**: Hooks for change, confirm, and cancel events
-//!
-//! # Example
-//!
-//! ```ignore
-//! let picker = MultiSelectPicker::new(
-//!     "Select Items".to_string(),
-//!     Some("Choose which items to enable".to_string()),
-//!     app_event_tx,
-//! )
-//! .items(vec![
-//!     MultiSelectItem { id: "a".into(), name: "Item A".into(), description: None, enabled: true },
-//!     MultiSelectItem { id: "b".into(), name: "Item B".into(), description: None, enabled: false },
-//! ])
-//! .on_confirm(|selected_ids, tx| { /* handle confirmation */ })
-//! .build();
-//! ```

-//! Paste-burst detection for terminals without bracketed paste.
-//!
-//! On some platforms (notably Windows), pastes often arrive as a rapid stream of
-//! `KeyCode::Char` and `KeyCode::Enter` key events rather than as a single "paste" event.
-//! In that mode, the composer needs to:
-//!
-//! - Prevent transient UI side effects (e.g. toggles bound to `?`) from triggering on pasted text.
-//! - Ensure Enter is treated as a newline *inside the paste*, not as "submit the message".
-//! - Avoid flicker caused by inserting a typed prefix and then immediately reclassifying it as
-//!   paste once enough chars have arrived.
-//!
-//! This module provides the `PasteBurst` state machine. `ChatComposer` feeds it only "plain"
-//! character events (no Ctrl/Alt) and uses its decisions to either:
-//!
-//! - briefly hold a first ASCII char (flicker suppression),
-//! - buffer a burst as a single pasted string, or
-//! - let input flow through as normal typing.
-//!
-//! For the higher-level view of how `PasteBurst` integrates with `ChatComposer`, see
-//! `docs/tui-chat-composer.md`.
-//!
-//! # Call Pattern
-//!
-//! `PasteBurst` is a pure state machine: it never mutates the textarea directly. The caller feeds
-//! it events and then applies the chosen action:
-//!
-//! - For each plain `KeyCode::Char`, call [`PasteBurst::on_plain_char`] (ASCII) or
-//!   [`PasteBurst::on_plain_char_no_hold`] (non-ASCII/IME).
-//! - If the decision indicates buffering, the caller appends to `PasteBurst.buffer` via
-//!   [`PasteBurst::append_char_to_buffer`].
-//! - On a UI tick, call [`PasteBurst::flush_if_due`]. If it returns [`FlushResult::Typed`], insert
-//!   that char as normal typing. If it returns [`FlushResult::Paste`], treat the returned string as
-//!   an explicit paste.
-//! - Before applying non-char input (arrow keys, Ctrl/Alt modifiers, etc.), use
-//!   [`PasteBurst::flush_before_modified_input`] to avoid leaving buffered text "stuck", and then
-//!   [`PasteBurst::clear_window_after_non_char`] so subsequent typing does not get grouped into a
-//!   previous burst.
-//!
-//! # State Variables
-//!
-//! This state machine is encoded in a few fields with slightly different meanings:
-//!
-//! - `active`: true while we are still *actively* accepting characters into the current burst.
-//! - `buffer`: accumulated burst text that will eventually flush as a single `Paste(String)`.
-//!   A non-empty buffer is treated as "in burst context" even if `active` has been cleared.
-//! - `pending_first_char`: a single held ASCII char used for flicker suppression. The caller must
-//!   not render this char until it either becomes part of a burst (`BeginBufferFromPending`) or
-//!   flushes as a normal typed char (`FlushResult::Typed`).
-//! - `last_plain_char_time`/`consecutive_plain_char_burst`: the timing/count heuristic for
-//!   "paste-like" streams.
-//! - `burst_window_until`: the Enter suppression window ("Enter inserts newline") that outlives the
-//!   buffer itself.
-//!
-//! # Timing Model
-//!
-//! There are two timeouts:
-//!
-//! - `PASTE_BURST_CHAR_INTERVAL`: maximum delay between consecutive "plain" chars for them to be
-//!   considered part of a single burst. It also bounds how long `pending_first_char` is held.
-//! - `PASTE_BURST_ACTIVE_IDLE_TIMEOUT`: once buffering is active, how long to wait after the last
-//!   char before flushing the accumulated buffer as a paste.
-//!
-//! `flush_if_due()` intentionally uses `>` (not `>=`) when comparing elapsed time, so tests and UI
-//! ticks should cross the threshold by at least 1ms (see `recommended_flush_delay()`).
-//!
-//! # Retro Capture Details
-//!
-//! Retro-capture exists to handle the case where we initially inserted characters as "normal
-//! typing", but later decide that the stream is paste-like. When that happens, we retroactively
-//! remove a prefix of already-inserted text from the textarea and move it into the burst buffer so
-//! the eventual `handle_paste(...)` sees a contiguous pasted string.
-//!
-//! Retro-capture mostly matters on paths that do *not* hold the first character (non-ASCII/IME
-//! input, and retro-grab scenarios). The ASCII path usually prefers
-//! `RetainFirstChar -> BeginBufferFromPending`, which avoids needing retro-capture at all.
-//!
-//! Retro-capture is expressed in terms of characters, not bytes:
-//!
-//! - `CharDecision::BeginBuffer { retro_chars }` uses `retro_chars` as a character count.
-//! - `decide_begin_buffer(now, before_cursor, retro_chars)` turns that into a UTF-8 byte range by
-//!   calling `retro_start_index()`.
-//! - `RetroGrab.start_byte` is a byte index into the `before_cursor` slice; callers must clamp the
-//!   cursor to a char boundary before slicing so `start_byte..cursor` is always valid UTF-8.
-//!
-//! # Clearing vs Flushing
-//!
-//! There are two ways callers end burst handling, and they are not interchangeable:
-//!
-//! - `flush_before_modified_input()` returns the buffered text (and/or a pending first ASCII char)
-//!   so the caller can apply it through the normal paste path before handling an unrelated input.
-//! - `clear_window_after_non_char()` clears the *classification window* so subsequent typing does
-//!   not get grouped into the previous burst. It assumes the caller has already flushed any buffer
-//!   because it clears `last_plain_char_time`, which means `flush_if_due()` will not flush a
-//!   non-empty buffer until another plain char updates the timestamp.
-//!
-//! # States (Conceptually)
-//!
-//! - **Idle**: no buffered text, no pending char.
-//! - **Pending first char**: `pending_first_char` holds one ASCII char for up to
-//!   `PASTE_BURST_CHAR_INTERVAL` while we wait to see if a burst follows.
-//! - **Active buffer**: `active`/`buffer` holds paste-like content until it times out and flushes.
-//! - **Enter suppress window**: `burst_window_until` keeps Enter treated as newline briefly after
-//!   burst activity so multiline pastes stay grouped.
-//!
-//! # ASCII vs Non-ASCII
-//!
-//! - [`PasteBurst::on_plain_char`] may return [`CharDecision::RetainFirstChar`] to hold the first
-//!   ASCII char and avoid flicker.
-//! - [`PasteBurst::on_plain_char_no_hold`] never holds (used for IME/non-ASCII paths), since
-//!   holding a non-ASCII character can feel like dropped input.
-//!
-//! # Contract With `ChatComposer`
-//!
-//! `PasteBurst` does not mutate the UI text buffer on its own. The caller (`ChatComposer`) must
-//! interpret decisions and apply the corresponding UI edits:
-//!
-//! - For each plain ASCII `KeyCode::Char`, call [`PasteBurst::on_plain_char`].
-//!   - [`CharDecision::RetainFirstChar`]: do **not** insert the char into the textarea yet.
-//!   - [`CharDecision::BeginBufferFromPending`]: call [`PasteBurst::append_char_to_buffer`] for the
-//!     current char (the previously-held char is already in the burst buffer).
-//!   - [`CharDecision::BeginBuffer { retro_chars }`]: consider retro-capturing the already-inserted
-//!     prefix by calling [`PasteBurst::decide_begin_buffer`]. If it returns `Some`, remove the
-//!     returned `start_byte..cursor` range from the textarea and then call
-//!     [`PasteBurst::append_char_to_buffer`] for the current char. If it returns `None`, fall back
-//!     to normal insertion.
-//!   - [`CharDecision::BufferAppend`]: call [`PasteBurst::append_char_to_buffer`].
-//!
-//! - For each plain non-ASCII `KeyCode::Char`, call [`PasteBurst::on_plain_char_no_hold`] and then:
-//!   - If it returns `Some(CharDecision::BufferAppend)`, call
-//!     [`PasteBurst::append_char_to_buffer`].
-//!   - If it returns `Some(CharDecision::BeginBuffer { retro_chars })`, call
-//!     [`PasteBurst::decide_begin_buffer`] as above (and if buffering starts, remove the grabbed
-//!     prefix from the textarea and then append the current char to the buffer).
-//!   - If it returns `None`, insert normally.
-//!
-//! - Before applying non-char input (or any input that should not join a burst), call
-//!   [`PasteBurst::flush_before_modified_input`] and pass the returned string (if any) through the
-//!   normal paste path.
-//!
-//! - Periodically (e.g. on a UI tick), call [`PasteBurst::flush_if_due`].
-//!   - [`FlushResult::Typed`]: insert that single char as normal typing.
-//!   - [`FlushResult::Paste`]: treat the returned string as an explicit paste.
-//!
-//! - When a non-plain key is pressed (Ctrl/Alt-modified input, arrows, etc.), callers should use
-//!   [`PasteBurst::clear_window_after_non_char`] to prevent the next keystroke from being
-//!   incorrectly grouped into a previous burst.

-//! The main Codex TUI chat surface.
-//!
-//! `ChatWidget` consumes protocol events, builds and updates history cells, and drives rendering
-//! for both the main viewport and overlay UIs.
-//!
-//! The UI has both committed transcript cells (finalized `HistoryCell`s) and an in-flight active
-//! cell (`ChatWidget.active_cell`) that can mutate in place while streaming (often representing a
-//! coalesced exec/tool group). The transcript overlay (`Ctrl+T`) renders committed cells plus a
-//! cached, render-only live tail derived from the current active cell so in-flight tool calls are
-//! visible immediately.
-//!
-//! The transcript overlay is kept in sync by `App::overlay_forward_event`, which syncs a live tail
-//! during draws using `active_cell_transcript_key()` and `active_cell_transcript_lines()`. The
-//! cache key is designed to change when the active cell mutates in place or when its transcript
-//! output is time-dependent so the overlay can refresh its cached tail without rebuilding it on
-//! every draw.
-//!
-//! The bottom pane exposes a single "task running" indicator that drives the spinner and interrupt
-//! hints. This module treats that indicator as derived UI-busy state: it is set while an agent turn
-//! is in progress and while MCP server startup is in progress. Those lifecycles are tracked
-//! independently (`agent_turn_running` and `mcp_startup_status`) and synchronized via
-//! `update_task_running_state`.
-//!
-//! For preamble-capable models, assistant output may include commentary before
-//! the final answer. During streaming we hide the status row to avoid duplicate
-//! progress indicators; once commentary completes and stream queues drain, we
-//! re-show it so users still see turn-in-progress state between output bursts.

-
-• I’m evaluating how binary size is influenced by various factors. There are
-  many binaries, such as codex and codex-exec, which include dependencies by
-  default, pulling in features like Tokio and hyper. For instance, reqwest
-  includes default features like TLS through rustls. If default features remain
-  enabled, it inflates the size with many additional components. I notice
-  that for musl targets, using vendored builds of OpenSSL could significantly
-  increase binary size. This is quite the intricate web of dependencies!
-
-  Analyzing musl and binary size
-
-  I’m considering the implications of building for musl with static linking.
-  In this case, OpenSSL might come into play through some crates, but reqwest
-  defaults to using rustls, although openssl-sys vendored could increase
-  binary size. It’s interesting to think about whether they’re targeting musl,
-  especially since it seems they might often be building for Mac and Linux with
-  dynamic linking instead.
-
-  I also realize there’s a difference between debug and release builds — release
-  should be smaller due to optimizations, but if they’re defaulting to debug
-  builds, that could lead to much larger binaries.
-
-  Assessing crate impacts on size
-
-  I need to be precise when analyzing binary sizes from various crates. Some
-  crates, like ratatui-image, include heavy features such as libjpeg decoders,
-  which can really bulk things up. Then there are the tree-sitter crates that
-  contain large static grammar tables, adding significant size. The starlark
-  crate and tracing-subscriber also contribute to size increases.
-
-  With static linking per binary being standard in Rust, it leads to multiple
-  copies of the same dependencies unless cdylibs are used. That makes the
-  compile times longer, but using LTO helps reduce bloat somewhat through
-  deduplication.
-
-  Evaluating binary size factors
-
-  Having multiple binaries indeed increases the overall size significantly.
-  I'm considering options like upgrading to "opt-level = 'z'" or using
-  "strip=debuginfo" for reducing size. It's interesting that while the profile
-  only sets symbols for stripping, not debuginfo, this could inflate sizes if
-  retained in release builds.
-
-  The distinction between "symbols" and "debuginfo" is critical; "symbols"
-  keeps debug information which may not align with the goal of minimizing
-  size. I’d like to verify with the Rust documentation, but my network access
-  is restricted.
-
-  Explaining large binary sizes
-
-  I’m analyzing why binaries in this project are so large. The primary reasons
-  include monolithic static linking, where each binary includes the full
-  dependency graph without shared libraries. Heavy dependencies such as reqwest,
-  hyper, and TLS components also contribute significantly to size, along with
-  image decoders and other libraries.
-
-  Using MUSL targets means vendored OpenSSL can drastically increase the
-  size due to static linking. Furthermore, if the release profile keeps debug
-  information due to using "strip = symbols," that can lead to larger binaries
-  as well. It’s a mix of several factors, including panic strategies and
-  platform-specific linking behavior.
-
-  Identifying binary size contributors
-
-  I’m considering why binaries are still large even without static linking. The
-  tracing-subscriber crate potentially adds weight because it includes regex,
-  though it can sometimes use a lighter version. References from files like
-  "core/Cargo.toml" show dependencies like reqwest and tokio, while the tui uses
-  the image crate.
-
-  To present this clearly, I’ll format the final answer with two main sections:
-  "Main Causes" and "Build-Mode Notes." I can also include brief suggestions for
-  reducing size, but I want to stay focused on answering the user's question.
-
-─ Worked for 0s ────────────────────────────────────────────────────────────────
-
-• Here’s what’s driving size in this workspace’s binaries.
-
-  Main Causes
-
-  - Static linking style: Each bin (codex, codex-tui, codex-exec, codex-mcp-
-  server, etc.) statically links its full dependency graph, so common code isn’t
-  shared at runtime across executables.
-  - Heavy deps (HTTP/TLS): reqwest brings in Hyper, HTTP/2, compressors,
-  and a TLS stack (rustls by default; OpenSSL on musl). In core, login, tui,
-  and ollama you enable reqwest with json/stream, which still pulls a large
-  transitive set.
-  - Image/terminal stack: codex-tui includes image (with jpeg), ratatui,
-  crossterm, and ratatui-image, which together contribute significant code size
-  (decoders, pixel ops, terminal backends).
-  - Parsers/VMs: tree-sitter + tree-sitter-bash (in core and apply-patch) and
-  starlark (in execpolicy) include sizeable parser/VM tables and runtimes.
-  - Tokio runtime: Broad tokio features (rt-multi-thread, macros, process,
-  signal) across many crates inflate code size even if only subsets are used
-  per bin.
-  - Panic + backtraces: Default panic = unwind and backtrace support keep
-  unwinding tables and symbols that add weight.
-  - Per-target OpenSSL (musl): For *-unknown-linux-musl, core enables openssl-
-  sys with vendored, compiling OpenSSL into the binary—this adds multiple
-  megabytes per executable.
-
-  Build-Mode Notes
-
-  - Release settings: You use lto = "fat" and codegen-units = 1 (good for size),
-  but strip = "symbols" keeps debuginfo. Debuginfo is often the largest single
-  contributor; if you build in release with that setting, binaries can still
-  be large.
-  - Debug builds: cargo build (dev profile) includes full debuginfo, no LTO, and
-  assertions—outputs are much larger than cargo build --release.
-
-  If you want, I can outline targeted trims (e.g., strip = "debuginfo", opt-
-  level = "z", panic abort, tighter tokio/reqwest features) and estimate impact
-  per binary.

-//! Exercises `ChatWidget` event handling and rendering invariants.

-//! These tests treat the widget as the adapter between `codex_protocol::protocol::EventMsg` inputs and

-//! Clipboard text copy support for `/copy` in the TUI.
-//!
-//! This module owns the policy for getting plain text from the running Codex
-//! process into the user's system clipboard. It prefers the direct native
-//! clipboard path when the current machine is also the user's desktop, but it
-//! intentionally changes strategy in environments where a "local" clipboard
-//! would be the wrong one: SSH sessions use OSC 52 so the user's terminal can
-//! proxy the copy back to the client, and WSL shells fall back to
-//! `powershell.exe` because Linux-side clipboard providers often cannot reach
-//! the Windows clipboard reliably.
-//!
-//! The module is deliberately narrow. It only handles text copy, returns
-//! user-facing error strings for the chat UI, and does not try to expose a
-//! reusable clipboard abstraction for the rest of the application. Image paste
-//! and WSL environment detection live in neighboring modules.
-//!
-//! The main operational contract is that callers get one best-effort copy
-//! attempt and a readable failure message. The selection between native copy,
-//! OSC 52, and WSL fallback is centralized here so `/copy` does not have to
-//! understand platform-specific clipboard behavior.

-//! Renders unified diffs with line numbers, gutter signs, and optional syntax
-//! highlighting.
-//!
-//! Each `FileChange` variant (Add / Delete / Update) is rendered as a block of
-//! diff lines, each prefixed by a right-aligned line number, a gutter sign
-//! (`+` / `-` / ` `), and the content text.  When a recognized file extension
-//! is present, the content text is syntax-highlighted using
-//! [`crate::render::highlight`].
-//!
-//! **Theme-aware styling:** diff backgrounds adapt to the terminal's
-//! background lightness via [`DiffTheme`].  Dark terminals get muted tints
-//! (`#212922` green, `#3C170F` red); light terminals get GitHub-style pastels
-//! with distinct gutter backgrounds for contrast. The renderer uses fixed
-//! palettes for truecolor / 256-color / 16-color terminals so add/delete lines
-//! remain visually distinct even when quantizing to limited palettes.
-//!
-//! **Syntax-theme scope backgrounds:** when the active syntax theme defines
-//! background colors for `markup.inserted` / `markup.deleted` (or fallback
-//! `diff.inserted` / `diff.deleted`) scopes, those colors override the
-//! hardcoded palette for rich color levels.  ANSI-16 mode always uses
-//! foreground-only styling regardless of theme scope backgrounds.
-//!
-//! **Highlighting strategy for `Update` diffs:** the renderer highlights each
-//! hunk as a single concatenated block rather than line-by-line.  This
-//! preserves syntect's parser state across consecutive lines within a hunk
-//! (important for multi-line strings, block comments, etc.).  Cross-hunk state
-//! is intentionally *not* preserved because hunks are visually separated and
-//! re-synchronize at context boundaries anyway.
-//!
-//! **Wrapping:** long lines are hard-wrapped at the available column width.
-//! Syntax-highlighted spans are split at character boundaries with styles
-//! preserved across the split so that no color information is lost.

-/// via the raw `has_wt_session` flag.
-///
-/// These signals are intentionally not equivalent: `terminal_name` is a
-/// derived classification with `TERM_PROGRAM` precedence, so `WT_SESSION`
-/// can be present while `terminal_name` is not `WindowsTerminal`.
-///
-/// When `WT_SESSION` is present, we promote to truecolor unconditionally
-/// unless `FORCE_COLOR` is set. This keeps Windows Terminal rendering rich
-/// by default while preserving explicit `FORCE_COLOR` user intent.
-///
-/// Outside `WT_SESSION`, only ANSI-16 is promoted for identified
-/// `WindowsTerminal` sessions; `Unknown` stays conservative.

-// -- Style helpers ------------------------------------------------------------
-//
-// Each diff line is composed of three visual regions, styled independently:
-//
-//   ┌──────────┬──────┬──────────────────────────────────────────┐
-//   │  gutter  │ sign │              content                     │
-//   │ (line #) │ +/-  │  (plain or syntax-highlighted text)      │
-//   └──────────┴──────┴──────────────────────────────────────────┘
-//
-// A fourth, full-width layer — `line_bg` — is applied via `RtLine::style()`
-// so that the background tint extends from the leftmost column to the right
-// edge of the terminal, including any padding beyond the content.
-//
-// On dark terminals, the sign and content share one style (colored fg + tinted
-// bg), and the gutter is simply dimmed.  On light terminals, sign and content
-// are split: the sign gets only a colored foreground (no bg, so the line bg
-// shows through), while content relies on the line bg alone; the gutter gets
-// an opaque, more-saturated background so line numbers stay readable against
-// the pastel line tint.
-
-/// Full-width background applied to the `RtLine` itself (not individual spans).
-/// Context lines intentionally leave the background unset so the terminal
-/// default shows through.

-//! Transcript/history cells for the Codex TUI.
-//!
-//! A `HistoryCell` is the unit of display in the conversation UI, representing both committed
-//! transcript entries and, transiently, an in-flight active cell that can mutate in place while
-//! streaming.
-//!
-//! The transcript overlay (`Ctrl+T`) appends a cached live tail derived from the active cell, and
-//! that cached tail is refreshed based on an active-cell cache key. Cells that change based on
-//! elapsed time expose `transcript_animation_tick()`, and code that mutates the active cell in place
-//! bumps the active-cell revision tracked by `ChatWidget`, so the cache key changes whenever the
-//! rendered transcript output can change.

-//! Overlay UIs rendered in an alternate screen.
-//!
-//! This module implements the pager-style overlays used by the TUI, including the transcript
-//! overlay (`Ctrl+T`) that renders a full history view separate from the main viewport.
-//!
-//! The transcript overlay renders committed transcript cells plus an optional render-only live tail
-//! derived from the current in-flight active cell. Because rebuilding wrapped `Line`s on every draw
-//! can be expensive, that live tail is cached and only recomputed when its cache key changes, which
-//! is derived from the terminal width (wrapping), an active-cell revision (in-place mutations), the
-//! stream-continuation flag (spacing), and an animation tick (time-based spinner/shimmer output).
-//!
-//! The transcript overlay live tail is kept in sync by `App` during draws: `App` supplies an
-//! `ActiveCellTranscriptKey` and a function to compute the active cell transcript lines, and
-//! `TranscriptOverlay::sync_live_tail` uses the key to decide when the cached tail must be
-//! recomputed. `ChatWidget` is responsible for producing a key that changes when the active cell
-//! mutates in place or when its transcript output is time-dependent.

-//! Syntax highlighting engine for the TUI.
-//!
-//! Wraps [syntect] with the [two_face] grammar and theme bundles to provide
-//! ~250-language syntax highlighting and 32 bundled color themes.  The module
-//! owns four process-global singletons:
-//!
-//! | Singleton | Type | Purpose |
-//! |---|---|---|
-//! | `SYNTAX_SET` | `OnceLock<SyntaxSet>` | Grammar database, immutable after init |
-//! | `THEME` | `OnceLock<RwLock<Theme>>` | Active color theme, swappable at runtime |
-//! | `THEME_OVERRIDE` | `OnceLock<Option<String>>` | Persisted user preference (write-once) |
-//! | `CODEX_HOME` | `OnceLock<Option<PathBuf>>` | Root for custom `.tmTheme` discovery |
-//!
-//! **Lifecycle:** call [`set_theme_override`] once at startup (after the final
-//! config is resolved) to persist the user preference and seed the `THEME`
-//! lock.  After that, [`set_syntax_theme`] and [`current_syntax_theme`] can
-//! swap/snapshot the theme for live preview.  All highlighting functions read
-//! the theme via `theme_lock()`.
-//!
-//! **Guardrails:** inputs exceeding 512 KB or 10 000 lines are rejected early
-//! (returns `None`) to prevent pathological CPU/memory usage.  Callers must
-//! fall back to plain unstyled text.

-/// Interactive session picker that lists recorded rollout files with simple
-/// search and pagination.
-///
-/// The picker displays sessions in a table with timestamp columns (created/updated),
-/// git branch, working directory, and conversation preview. Users can toggle
-/// between sorting by creation time and last-updated time using the Tab key.
-///
-/// Sessions are loaded on-demand via cursor-based pagination. The backend
-/// `RolloutRecorder::list_threads` returns pages ordered by the selected sort key,
-/// and the picker deduplicates across pages to handle overlapping windows when
-/// new sessions appear during pagination.
-///
-/// Filtering happens in two layers:
-/// 1. Provider and source filtering at the backend (only interactive CLI sessions
-///    for the current model provider).
-/// 2. Working-directory filtering at the picker (unless `--all` is passed).

-**Codex just got an upgrade. Introducing gpt-5.3-codex.**
-
-Codex is now powered by gpt-5.3-codex, our most capable agentic coding model yet. It's built for long-running, project-scale work, with mid-turn steering + frequent progress updates so you can collaborate while it runs (and it's faster too).
-
-Learn more: https://openai.com/index/introducing-gpt-5-3-codex/
-
-You can keep using gpt-5.1-codex if you prefer.

-**Codex just got an upgrade. Introducing gpt-5.3-codex.**
-
-Codex is now powered by gpt-5.3-codex, our most capable agentic coding model yet. It's built for long-running, project-scale work, with mid-turn steering + frequent progress updates so you can collaborate while it runs (and it's faster too).
-
-Learn more: https://openai.com/index/introducing-gpt-5-3-codex/
-
-You can keep using gpt-5.1-codex if you prefer.

-//! Adaptive stream chunking policy for commit animation ticks.
-//!
-//! This policy preserves the baseline user experience while adapting to bursty
-//! stream input. In [`ChunkingMode::Smooth`], one queued line is drained per
-//! baseline commit tick. When queue pressure rises, it switches to
-//! [`ChunkingMode::CatchUp`] and drains queued backlog immediately so display
-//! lag converges as quickly as possible.
-//!
-//! The policy is source-agnostic: it depends only on queue depth and queue
-//! age from [`QueueSnapshot`]. It does not branch on source identity or explicit
-//! throughput targets.
-//!
-//! # Mental model
-//!
-//! Think of this as a two-gear system:
-//!
-//! - [`ChunkingMode::Smooth`]: steady baseline display pacing.
-//! - [`ChunkingMode::CatchUp`]: full queue draining while backlog exists.
-//!
-//! The transition logic intentionally uses hysteresis:
-//!
-//! - enter catch-up on higher-pressure thresholds
-//! - exit catch-up on lower-pressure thresholds, held for [`EXIT_HOLD`]
-//! - after exit, suppress immediate re-entry for [`REENTER_CATCH_UP_HOLD`]
-//!   unless backlog is severe
-//!
-//! This avoids rapid gear-flapping near threshold boundaries.
-//!
-//! # Policy flow
-//!
-//! On each decision tick, [`AdaptiveChunkingPolicy::decide`] does:
-//!
-//! 1. If queue is empty, reset to [`ChunkingMode::Smooth`].
-//! 2. If currently smooth, call [`AdaptiveChunkingPolicy::maybe_enter_catch_up`].
-//! 3. If currently catch-up, call [`AdaptiveChunkingPolicy::maybe_exit_catch_up`].
-//! 4. Build [`DrainPlan`] (`Single` for smooth, `Batch(queued_lines)` for catch-up).
-//!
-//! # Concrete examples
-//!
-//! With current defaults:
-//!
-//! - `Smooth` drains one line per commit tick.
-//! - `CatchUp` drains all currently queued lines in a tick.
-//!
-//! # Tuning guide (in code terms)
-//!
-//! Prefer tuning in this order so causes remain clear:
-//!
-//! 1. enter/exit thresholds: [`ENTER_QUEUE_DEPTH_LINES`], [`ENTER_OLDEST_AGE`],
-//!    [`EXIT_QUEUE_DEPTH_LINES`], [`EXIT_OLDEST_AGE`]
-//! 2. hysteresis windows: [`EXIT_HOLD`], [`REENTER_CATCH_UP_HOLD`]
-//! 3. severe gates: [`SEVERE_QUEUE_DEPTH_LINES`], [`SEVERE_OLDEST_AGE`]
-//!
-//! Symptom-oriented adjustments:
-//!
-//! - lag starts too late: lower enter thresholds
-//! - frequent smooth/catch-up chatter: increase hold windows, or tighten exit
-//!   thresholds
-//! - catch-up re-enters too eagerly after exit: increase re-entry hold
-//!
-//! # Responsibilities
-//!
-//! - track mode and hysteresis state
-//! - produce deterministic [`ChunkingDecision`] values from queue snapshots
-//! - preserve queue order by draining from queue head only
-//!
-//! # Non-responsibilities
-//!
-//! - scheduling commit ticks
-//! - reordering stream lines
-//! - transport/source-specific semantics
-//!
-//! Markdown docs remain supplemental:
-//!
-//! - `docs/tui-stream-chunking-review.md`
-//! - `docs/tui-stream-chunking-tuning.md`
-//! - `docs/tui-stream-chunking-validation.md`

-//! Orchestrates commit-tick drains across streaming controllers.
-//!
-//! This module bridges queue-based chunking policy (`chunking`) with the concrete stream
-//! controllers (`controller`). Callers provide the current controllers and tick scope; the module
-//! computes queue pressure, selects a drain plan, applies it, and returns emitted history cells.
-//!
-//! The module preserves ordering by draining only from controller queue heads. It does not schedule
-//! ticks and it does not mutate UI state directly; callers remain responsible for animation events
-//! and history insertion side effects.
-//!
-//! The main flow is:
-//! [`run_commit_tick`] -> [`stream_queue_snapshot`] -> [`QueueSnapshot`] ->
-//! [`resolve_chunking_plan`] -> [`ChunkingDecision`]/[`DrainPlan`] ->
-//! [`apply_commit_tick_plan`] -> [`CommitTickOutput`].

-//! Terminal-title output helpers for the TUI.
-//!
-//! This module owns the low-level OSC title write path and the sanitization
-//! that happens immediately before we emit it. It is intentionally narrow:
-//! callers decide when the title should change and whether an empty title means
-//! "leave the old title alone" or "clear the title Codex last wrote".
-//! This module does not attempt to read or restore the terminal's previous
-//! title because that is not portable across terminals.
-//!
-//! Sanitization is necessary because title content is assembled from untrusted
-//! text sources such as model output, thread names, project paths, and config.
-//! Before we place that text inside an OSC sequence, we strip:
-//! - control characters that could terminate or reshape the escape sequence
-//! - bidi/invisible formatting codepoints that can visually reorder or hide
-//!   text (the same family of issues discussed in Trojan Source writeups)
-//! - redundant whitespace that would make titles noisy or hard to scan

-//! Builds the `/theme` picker dialog for the TUI.
-//!
-//! The picker lists all bundled themes plus any custom `.tmTheme` files found
-//! under `{CODEX_HOME}/themes/`.  It provides:
-//!
-//! - **Live preview:** the `on_selection_changed` callback swaps the runtime
-//!   syntax theme as the user navigates, giving instant visual feedback in both
-//!   the preview panel and any visible code blocks.
-//! - **Cancel-restore:** on dismiss (Esc / Ctrl+C) the `on_cancel` callback
-//!   restores the theme snapshot taken when the picker opened.
-//! - **Persist on confirm:** the `AppEvent::SyntaxThemeSelected` action persists
-//!   `[tui] theme = "..."` to `config.toml` via `ConfigEditsBuilder`.
-//!
-//! Two preview renderables adapt to terminal width:
-//!
-//! - `ThemePreviewWideRenderable` -- vertically centered, inset by 2 columns,
-//!   shown in the side panel when the terminal is wide enough for side-by-side
-//!   layout (>= 44-column side panel and >= 40-column list).
-//! - `ThemePreviewNarrowRenderable` -- compact 4-line snippet stacked below the
-//!   list when side-by-side does not fit.

-//! Event stream plumbing for the TUI.
-//!
-//! - [`EventBroker`] holds the shared crossterm stream so multiple callers reuse the same
-//!   input source and can drop/recreate it on pause/resume without rebuilding consumers.
-//! - [`TuiEventStream`] wraps a draw event subscription plus the shared [`EventBroker`] and maps crossterm
-//!   events into [`TuiEvent`].
-//! - [`EventSource`] abstracts the underlying event producer; the real implementation is
-//!   [`CrosstermEventSource`] and tests can swap in [`FakeEventSource`].
-//!
-//! The motivation for dropping/recreating the crossterm event stream is to enable the TUI to fully relinquish stdin.
-//! If the stream is not dropped, it will continue to read from stdin even if it is not actively being polled
-//! (due to how crossterm's EventStream is implemented), potentially stealing input from other processes reading stdin,
-//! like terminal text editors. This race can cause missed input or capturing terminal query responses (for example, OSC palette/size queries)
-//! that the other process expects to read. Stopping polling, instead of dropping the stream, is only sufficient when the
-//! pause happens before the stream enters a pending state; otherwise the crossterm reader thread may keep reading
-//! from stdin, so the safer approach is to drop and recreate the event stream when we need to hand off the terminal.
-//!
-//! See https://ratatui.rs/recipes/apps/spawn-vim/ and https://www.reddit.com/r/rust/comments/1f3o33u/myterious_crossterm_input_after_running_vim for more details.

-//! Word-wrapping with URL-aware heuristics.
-//!
-//! The TUI renders text that frequently contains URLs — command output,
-//! markdown, agent messages, tool-call results. Standard `textwrap`
-//! hyphenation treats `/` and `-` as split points, which breaks URLs
-//! across lines and makes them unclickable in terminal emulators.
-//!
-//! This module provides two wrapping paths:
-//!
-//! - **Standard** (`word_wrap_line`, `word_wrap_lines`): delegates to
-//!   `textwrap` with the caller's options unchanged. Used when the
-//!   content is known to be plain prose.
-//! - **Adaptive** (`adaptive_wrap_line`, `adaptive_wrap_lines`):
-//!   inspects the line for URL-like tokens; if any are found, the
-//!   wrapping switches to `AsciiSpace` word separation and a custom
-//!   `WordSplitter` that refuses to split URL tokens. Non-URL tokens
-//!   on the same line still break at every character boundary (the
-//!   custom splitter returns all char indices for non-URL words).
-//!
-//! Callers that *might* encounter URLs should use the `adaptive_*`
-//! functions. Callers that definitely will not (code blocks, pure
-//! numeric output) can use the standard path for speed.
-//!
-//! URL detection is heuristic — see [`text_contains_url_like`] for the
-//! rules. False positives suppress hyphenation for that line; false
-//! negatives let a URL get split. The heuristic is intentionally
-//! conservative: file paths like `src/main.rs` are not matched.

-# Headers, primary, and secondary text
-
-- **Headers:** Use `bold`. For markdown with various header levels, leave in the `#` signs.
-- **Primary text:** Default.
-- **Secondary text:** Use `dim`.
-
-# Foreground colors
-
-- **Default:** Most of the time, just use the default foreground color. `reset` can help get it back.
-- **User input tips, selection, and status indicators:** Use ANSI `cyan`.
-- **Success and additions:** Use ANSI `green`.
-- **Errors, failures and deletions:** Use ANSI `red`.
-- **Codex:** Use ANSI `magenta`.
-
-# Avoid
-
-- Avoid custom colors because there's no guarantee that they'll contrast well or look good in various terminal color themes. (`shimmer.rs` is an exception that works well because we take the default colors and just adjust their levels.)
-- Avoid ANSI `black` & `white` as foreground colors because the default terminal theme color will do a better job. (Use `reset` if you need to in order to get those.) The exception is if you need contrast rendering over a manually colored background.
-- Avoid ANSI `blue` and `yellow` because for now the style guide doesn't use them. Prefer a foreground color mentioned above.
-
-(There are some rules to try to catch this in `clippy.toml`.)

Though the moon rose each evening, its pallid glow was always pierced by sparks that danced from the ancient Emberstone, a relic said to house a living fire. The stone rested in a cavern beneath the old Keep of Liora, guarded by the Order of Light, who swore to keep it untarnished from any mortal touch.\n\nAmong the village was a boy named Caelan. He had grown up hearing the legends – the tale of the Emberstone that kept the valley alive, of those who dared to steal its heart, and of the cursed ones who turned from the light. Caelan's mother, a healer known as Maeve, warned him never to venture beyond the river. Yet his eyes were always drawn toward the glimmering blue that peeked from the depths of the keep.\n\nOne crisp autumn night, a strange light fluttered across the sky, a comet streak that hung longer than it should. Caelan slipped away, his cloak a blur against the silvered riverbanks. He ran into the forest, guided by the comet’s tail, until he found himself at the base of the Keep of Liora. The stone walls gleamed, and an ancient oak's roots twined like silver cords across the stone.\n\nInside the keep, the corridors were maze-like, the air heavy with the scent of stone and lingering incense. At the heart of the labyrinth lay the Chamber of Ember, a vast vault carved out of obsidian, its walls pulsing faintly. The Emberstone lay atop a dais, surrounded by glyphs of forgotten runes that flickered like nervous fireflies.\n\nCaelan's heart hammered as he approached. He remembered Maeve's words: \"The fire of Evernight is not a tool to be wielded, but a covenant.\" Yet the ache of longing burned stronger—he wanted the light to pierce his village's nights, to cure the ailing crops, to ease his mother's grief. In a moment that felt like a choice between life and death he placed his palm upon the cool stone.\n\nSuddenly, a voice resonated through the chamber, not from any mortal ear, but from the very fire that had kept the valley alive: \"Child of ember, you seek light that cannot be taken. Do you dare become the flame?\"\n\nFrom behind him stepped a figure—tall and cloaked in a mantle of darkness that seemed to devour surrounding light. The figure revealed himself as Azrion the Keeper, the guardian who had sworn his oath to the stone for centuries. His eyes contained centuries of sorrow. \"I see your heart is pure,\" he intoned. \"But we are bound to the cycle.\"\n\nCaelan listened, heart pounding. \"I will spare the village,\" he said, voice trembling. \"But my mother suffers from illness. Will you grant me a sliver of fire?\"\n\nAzrion sighed. The Emberstone, however, had a memory. It remembered all that had come to its fore. The ancient runes whispered a verdict: the Emberstone can grant a single boon to a pure heart for a single sacrifice and that after the act, the light would be forever extinguished.\n\nCaelan realized the magnitude of his decision. If he used the fire, the valley would be plunged into darkness forever, but perhaps this one act would save a life. He closed his eyes, taking a deep breath, and placed the stone under a palm of his own. The ember sparked, a golden breath that curled into his fingers. Instinctively, he carried a vial of fire.\n\nHe returned to the village as the night fell. The flames were small and trembling, yet they lit the wounds of his mother's fever. Her eyes widened as warmth flooded through her bones. She smiled, a small but sincere expression of gratitude. \"My love,\" she whispered, \"you have saved me. I cannot say I understand how you'd choose our safety for a single flame...\"\n\nAfter that night, Caelan sealed the Emberstone back in its sanctuary and took the responsibility of keeping the light to the keep. Though the valley was robbed of its eternal ember, the memory lasted. His mother, healed, lived many more years. The village adapted, learning to find joy in the flicker of a single candle each night.\n\nYears turned into decades, and then centuries, until the Great Storm swept across Everglen, breaking the veil of the once unbreakable stone walls. The storm tore the Keep of Liora into ruins, leaving the Emberstone unprotected. In the ruins, whispers spread that someone from the past had stolen the ember, or that it had been left behind.\n\nIt was then that a new chapter began. A young woman named Aria, descendant of Caelan's line, with a keen curiosity and an unflinching resolve, would find her way. She would hear of the old stories of the stone's ember, the memory that carried the weight of choice.\n\nAria walked along the river and found herself at the ruins. She felt a pull in her heart and felt a stirring of destiny. She discovered, in the middle of the ruins, a cavity that glowed faintly in the moonlight: the Emberstone, broken, yet still lit, the same ember that had lived on Caelan's finger.\n\nWith careful hands, she reached for it. It was warm, and when she embraced it, she felt a vision: the valley under a storm, the light of the ember, Caelan's smile, the hope he brought to his mother. She understood then the weight of decisions, the price paid.\n\nAria understood that she must protect the ember, as the Order had done for centuries. She pledged to keep it safe again, so the valley might thrive, and the history of compassion that had guided generations might continue.\n\nSo the ember returned to its keep. It was a small, steady flame amid darkness, its light a reminder that even in times of great loss, there is always a spark that persists. The people of Everglen learned to cherish the ember, to pass down the stories of Caelan's sacrifice, and to respect its significance. The final ember did not extinguish the entire valley, it taught them something more profound: that the light is both a blessing and a burden. In Everglen, the fire was never just a physical flame; it became a guiding star—a symbol of humanity’s ability to make difficult choices, and the unwavering hope that even one ember can endure forever."}}}
