Skeletons for new files only; existing files change by exact edits, so no task overwrites an earlier one's work. Each task's tests were run against a reference built in order from master, with the gate at each step and mutations checked; each skeleton compiles and fails its tests, and every todo!() comment was read beside its signature. The reference is kept off this machine. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

//! Text from outside (model output, tool arguments, server errors) made safe to show: control

//! characters, zero-width and bidirectional marks, line separators and the BOM become `\uXXXX`.
|
|
//! Used by `bxctl` for the terminal and by `gatewayd` for Mattermost, so both show the same.

// The control bytes, the zero-width and Unicode line/paragraph separators, and the BOM. A code
