## Summary
When network requests were blocked, downstream code often had to infer
ask vs deny from free-form response text. That was brittle and led to
incorrect approval behavior.
This PR fixes the proxy side so blocked decisions are structured and
request metadata survives reliably.
## Description
- Blocked proxy responses now carry consistent structured policy
decision data.
- Request attempt metadata is preserved across proxy env paths
(including ALL_PROXY flows).
- Header stripping was tightened so we still remove unsafe forwarding
headers, but keep metadata needed for policy handling.
- Block messages were clarified (for example, allowlist miss vs explicit
deny).
- Added unified violation log entries so policy failures can be
inspected in one place.
- Added/updated tests for these behaviors.

## Notes / Edge Cases
- In steer mode while typing, the queue hint no longer replaces the mode
label; it renders as `tab to queue message · {Mode}`.
- Collapse priorities differ by state:
- With the queue hint active, `% context left` is hidden before
shortening or dropping the queue hint.
- In the empty + non-running state, `? for shortcuts` is dropped first,
and `% context left` is only shown if `(shift+tab to
cycle)` can also fit.
- Transient instructional states (`?` overlay, Esc hint, Ctrl+C/D
reminders, and flash/override hints) intentionally suppress the
mode label (and context) to focus the next action.
## Implementation Notes
- Renamed the base footer modes to make the state explicit:
`ComposerEmpty` and `ComposerHasDraft`, and compute the base mode
directly from emptiness.
- Unified collapse behavior in `single_line_footer_layout` for both base
modes, with:
- Queue-hint behavior that prefers keeping the queue hint over context.
- A cycle-hint guard that prevents context from reappearing after
`(shift+tab to cycle)` is dropped.
- Kept rendering responsibilities explicit:
- `single_line_footer_layout` decides what fits.
- `render_footer_line` renders a chosen line.
- `render_footer_from_props` renders the canonical mode-to-text mapping.
- Expanded snapshot coverage:
- Added `footer_collapse_snapshots` in `chat_composer.rs` to lock the
distinct collapse states across widths.
- Consolidated the width-aware snapshot helper usage (e.g.,
`snapshot_composer_state_with_width`,
`snapshot_footer_with_mode_indicator`).
# Terminal Detection Metadata for Per-Terminal Scroll Scaling
## Summary
Expand terminal detection into structured metadata (`TerminalInfo`) with
multiplexer awareness, plus a testable environment shim and
characterization tests.
## Context / Motivation
- TUI2 owns its viewport and scrolling model (see
`codex-rs/tui2/docs/tui_viewport_and_history.md`), so scroll behavior
must be consistent across terminals and independent of terminal
scrollback quirks.
- Prior investigations show mouse wheel scroll deltas vary noticeably by
terminal. To tune scroll scaling (line increments per wheel tick) we
need reliable terminal identification, including when running inside
tmux/zellij.
- tmux is especially tricky because it can mask the underlying terminal;
we now consult `tmux display-message` client termtype/name to attribute
sessions to the actual terminal rather than tmux itself.
- This remains backwards compatible with the existing OpenTelemetry
user-agent token because `user_agent()` is still derived from the same
environment signals (now via `TerminalInfo`).
## Changes
- Introduce `TerminalInfo`, `TerminalName`, and `Multiplexer` with
`TERM_PROGRAM`/`TERM`/multiplexer detection and user-agent formatting in
`codex-rs/core/src/terminal.rs`.
- Add an injectable `Environment` trait + `FakeEnvironment` for testing,
and comprehensive characterization tests covering known terminals, tmux
client termtype/name, and zellij.
- Document module usage and detection order; update `terminal_info()` to
be the primary interface for callers.
## Testing
- `cargo test -p codex-core terminal::tests`
- manually checked ghostty, iTerm2, Terminal.app, vscode, tmux, zellij,
Warp, alacritty, kitty.

```
## Notes / Follow-ups
- Next step is to wire `TerminalInfo` into TUI2’s scroll scaling
configuration and add a per-terminal tuning table.
- The log output in TUI2 helps validate real-world detection before
applying behavior changes.
Wait for newlines, then render markdown on a line by line basis. Word wrap it for the current terminal size and then spit it out line by line into the UI. Also adds tests and fixes some UI regressions.

I personally introduced it to dozens if not hundreds of projects already
and so far only positive feedback.
CI workflow has 'permissions' set only to 'read' so also should be safe.
Let me know if just want to take typo fixes in and get rid of the CI
