## What changed
- Treat plain, Shift-modified, and Windows AltGr character events as text-producing input for paste-burst detection.
- Exclude Super, Hyper, and Meta character events from paste bursts, flushing any pending text before handling them as shortcuts.
## Testing
- Add coverage for plain and Shift-modified spaces, shortcut-modified spaces, pending burst flushes, and platform-specific AltGr input.

Fixes#26025.
## Why
`/goal edit` opens `CustomPromptView`, which did not use the paste-burst
handling that protects the main composer when terminals deliver paste as
rapid key events. On Windows terminals, the first pasted newline could
be treated as Enter-to-submit, truncating the goal edit and leaving the
rest of the paste behind.
## What
This reuses `PasteBurst` in `CustomPromptView` as a lightweight
Enter-suppression detector for paste-like key streams. Characters still
insert directly, explicit paste still goes through the view paste path,
and ordinary text entry still submits on Enter.
## Context
`docs/tui-chat-composer.md` was removed by #20896 as part of removing
local-only docs/specs from the repository. I checked the #20896 file
list and the merge commit: the composer doc was deleted, not moved or
copied, and current `main` does not contain a replacement composer
narrative doc.
Current guidance should keep contributors and agents focused on the docs
that still exist: the module docs in `chat_composer.rs` and
`paste_burst.rs`.
## Summary
- Removes the scoped TUI bottom-pane AGENTS.md requirement to update
`docs/tui-chat-composer.md`.
- Removes stale module-doc references to that deleted narrative doc from
`chat_composer.rs` and `paste_burst.rs`.
## Validation
- Checked #20896 and the merge commit with rename/copy detection to
confirm `docs/tui-chat-composer.md` was deleted rather than moved.
- Searched current `main` for a replacement composer narrative doc.
- Not run; documentation-only change.
## Summary
Fixes#11678 by removing the Windows-specific
`PASTE_BURST_CHAR_INTERVAL` override. Windows now uses the same `8ms`
paste-burst character interval as macOS and Linux, which removes the
extra per-character hold that made fast typing and key repeat feel
delayed on Windows.
The paste-burst heuristic itself is unchanged, and the Windows-specific
active idle timeout remains in place. This PR only restores the shared
character-to-character burst threshold that decides whether adjacent
plain character events are part of a paste.
## Motivation
PR #9348 raised the Windows character interval from `8ms` to `30ms` to
protect the multiline paste behavior tracked in #2137, where pasted
newlines could be interpreted as submits in Windows terminals. That
fixed the paste failure, but it also made ordinary typing visibly laggy
because the TUI waits briefly before flushing a single typed character
while it checks whether a paste burst is forming.
The deployed behavior here is to remove that Windows-only delay and
return to the cross-platform threshold. Manual Windows validation of the
critical VS Code integrated terminal path shows multiline paste still
works with the final `8ms` value, including testing on VS Code
`1.107.0`.
## Testing
- `cargo test -p codex-tui`
- Manual Windows validation in VS Code integrated PowerShell with the
final `8ms` interval
This is a follow-up to https://github.com/openai/codex/pull/15922. That
previous PR deleted the old `tui` directory and left the new
`tui_app_server` directory in place. This PR renames `tui_app_server` to
`tui` and fixes up all references.
This is the part 1 of 2 PRs that will delete the `tui` /
`tui_app_server` split. This part simply deletes the existing `tui`
directory and marks the `tui_app_server` feature flag as removed. I left
the `tui_app_server` feature flag in place for now so its presence
doesn't result in an error. It is simply ignored.
Part 2 will rename the `tui_app_server` directory `tui`. I did this as
two parts to reduce visible code churn.
## Summary
- Increases `PASTE_BURST_CHAR_INTERVAL` from 8ms to 30ms on Windows to
fix multi-line paste issues in VS Code integrated terminal
- Follows existing pattern of platform-specific timing (like
`PASTE_BURST_ACTIVE_IDLE_TIMEOUT`)
## Problem
When pasting multi-line text in Codex CLI on Windows (especially VS Code
integrated terminal), only the first portion is captured before
auto-submit. The rest arrives as a separate message.
**Root cause**: VS Code's terminal emulation adds latency (~10-15ms per
character) between key events. The 8ms `PASTE_BURST_CHAR_INTERVAL`
threshold is too tight - characters arrive slower than expected, so
burst detection fails and Enter submits instead of inserting a newline.
## Solution
Use Windows-specific timing (30ms) for `PASTE_BURST_CHAR_INTERVAL`,
following the same pattern already used for
`PASTE_BURST_ACTIVE_IDLE_TIMEOUT` (60ms on Windows vs 8ms on Unix).
30ms is still fast enough to distinguish paste from typing (humans type
~200ms between keystrokes).
## Test plan
- [x] All existing paste_burst tests pass
- [ ] Test multi-line paste in VS Code integrated PowerShell on Windows
- [ ] Test multi-line paste in standalone Windows PowerShell
- [ ] Verify no regression on macOS/Linux
Fixes#2137

Replace the old timing-dependent non-ASCII paste test with deterministic
coverage by forcing an active `PasteBurst` and asserting the exact flush
payload.
Add focused unit tests for `PasteBurst` transitions, and add short
"Behavior:" rustdoc notes on chat composer tests to make the state
machine contracts explicit.
Add a narrative doc and inline rustdoc explaining how `ChatComposer`
and `PasteBurst` compose into a single state machine on terminals that
lack reliable bracketed paste (notably Windows).
This documents the key states, invariants, and integration points
(`handle_input_basic`, `handle_non_ascii_char`, tick-driven flush) so
future changes are easier to reason about.
## Summary
This PR builds _heavily_ on the work from @occurrent in #8021 - I've
only added a small fix, added additional tests, and propagated the
changes to tui2.
From the original PR:
> On Windows, Codex relies on PasteBurst for paste detection because
bracketed paste is not reliably available via crossterm.
>
> When pasted content starts with non-ASCII characters, input is routed
through handle_non_ascii_char, which bypasses the normal paste burst
logic. This change extends the paste burst window for that path, which
should ensure that Enter is correctly grouped as part of the paste.
## Testing
- [x] tested locally cross-platform
- [x] added regression tests

fixing drag/drop photos bug in codex
state of the world before:
sometimes, when you drag screenshots into codex, the image does not
properly render into context. instead, the file name is shown in
quotation marks.
https://github.com/user-attachments/assets/3c0e540a-505c-4ec0-b634-e9add6a73119
the screenshot is not actually included in agent context. the agent
needs to manually call the view_image tool to see the screenshot. this
can be unreliable especially if the image is part of a longer prompt and
is dependent on the agent going out of its way to view the image.
state of the world after:
https://github.com/user-attachments/assets/5f2b7bf7-8a3f-4708-85f3-d68a017bfd97
now, images will always be directly embedded into chat context
## Technical Details
- MacOS sends screenshot paths with a narrow no‑break space right before
the “AM/PM” suffix, which used to trigger our non‑ASCII fallback in the
paste burst detector.
- That fallback flushed the partially buffered paste immediately, so the
path arrived in two separate `handle_paste` calls (quoted prefix +
`PM.png'`). The split string could not be normalized to a real path, so
we showed the quoted filename instead of embedding the image.
- We now append non‑ASCII characters into the burst buffer when a burst
is already active. Finder’s payload stays intact, the path normalizes,
and the image attaches automatically.
- When no burst is active (e.g. during IME typing), non‑ASCII characters
still bypass the buffer so text entry remains responsive.
- ensure paste burst flush preserves ASCII characters before IME commits
- add regression test covering digit followed by Japanese text
submission

This PR fixes two edge cases in managing burst paste (mainly on power
shell).
Bugs:
- Needs an event key after paste to render the pasted items
> ChatComposer::flush_paste_burst_if_due() flushes on timeout. Called:
> - Pre-render in App on TuiEvent::Draw.
> - Via a delayed frame
>
BottomPane::request_redraw_in(ChatComposer::recommended_paste_flush_delay()).
- Parses two key events separately before starting parsing burst paste
> When threshold is crossed, pull preceding burst chars out of the
textarea and prepend to paste_burst_buffer, then keep buffering.
- Integrates with #2567 to bring image pasting to windows.
