## Progress log
- **2026-10-12:** `soundcraft-cli convert` rejects an unparsable or zero `--rate` and an unknown `--bit-depth` (exit 1, nothing written) instead of converting with a default (#256)
- **2026-10-12:** Timecode labels with huge fields no longer overflow: frame counts are computed in 128 bits and clamp, so `setup.current_timecode` and `session.format_time` saturate instead of failing (#248)
- **2026-10-12:** `session.format_time` with the smallest bar number no longer fails with an internal error: the bar offset saturates (#249)
- **2026-10-10 (UI docking):** Tracks and Groups, Clips, MIDI Editor, Memory Locations, and Undo History use movable panels. Edit and Mix retain separate arrangements; Clips and MIDI Editor belong to Edit. Transport, plug-in, and specialist utility windows retain their existing hosts. Panel moves and reset are available as UI commands, and saved UI preferences retain arrangements. Common toolbar and track record-enable buttons share interaction, accessible labels and keyboard focus through `craft-ui`, retaining blue tool selection and red record-arm states. No readiness percentage change.
- **2026-10-10** — Stage re-normalized to **pre-alpha** by the core-workflow gate (interface recording, MIDI recording and session interchange fail). Full re-measure against Pro Tools Ultimate 2026.4.1 and the standard

//! The folders automation may read and write.
//!
//! `soundcraft-cli mcp --automation-read-root <dir> --automation-write-root <dir>` confines the
//! files an agent's commands reach. [`AutomationRoots`] holds the two folders. While they are in
//! force, every path a command reads goes through [`check_read`] and every path it writes through [`check_write`]:
//!
//! - The path is made absolute against the working directory, as the file system reads it. Its
//! links are followed: for a file that doesn't exist yet, the links of its nearest existing
//! folder, the rest of the path being plain names (`..` below a missing folder is refused, and so
//! is a link that leads nowhere).
//! - The result must lie inside the root, compared by whole components (`/work2` isn't inside
//! `/work`), without regard to case on Windows.
//! - Read and write access are separate: a root given alone grants only its own kind of access.
//!
//! Roots are in force on a thread inside [`confine`], and in the whole process after
//! [`confine_process`] (`soundcraft-cli mcp`), except inside [`unconfined`]. Without roots
//! nothing is checked.
//!
//! A path is checked, then opened: a process that can change the folders in between (swapping in
//! a link) can still win that race. The roots keep an agent to the files it was given; they don't
//! guard against other programs on the computer.
