Moves the side panels from split frames into dock columns, using craft-ui's shared docking.

Layout

• Edit: Tracks and Groups is a full-height dock column on the left (168 pt), and Clips one on the right (230 pt). The MIDI editor sits under the session view, between the two docks. Memory Locations and Undo History float, as before.
• Mix: Tracks and Groups is a dock column on the left, beside the mixer.
• Panels dock into columns:
  • dropped on a group's middle, a panel joins it as a tab;
  • on its top or bottom third, it stacks a new group;
  • on a column edge, it makes a new column;
  • at an empty window edge, it makes a new dock.
    Floats dropped over the session view stay floating.

Saved layouts

• Saved settings carry a docking_version. Settings from before dock columns (no version) load with the new default layouts, once, with every other setting kept. Window configurations reset the same way when recalled.

Reopening panels

• A panel with no recorded place, or whose recorded anchor is gone, reopens at its default place:
  • Tracks and Groups and Clips go back into their dock, and a missing dock is rebuilt at its width;
  • the MIDI editor goes under the session view;
  • Memory Locations and Undo History float at their default rectangles.

Also

• Pins every craft-libs crate (craft-ui, craft-docpath, craft-media, craft-update) at craft-libs main db19c373, which contains the docking work (craft-libs#268, a0916808) and the updater fixes main uses.
• docs/control-protocol.md describes the default layout, drop rules and reopening; ROADMAP.md and docs/ui-parity.md are updated.

Tests

• default_layouts_put_the_side_lists_in_full_height_dock_columns: the Edit and Mix shapes, widths and drawn rectangles.
• a_tab_dropped_on_a_dock_group_joins_it_in_the_middle_and_stacks_below_in_the_lower_third: real pointer drags at points taken from the drawn rectangles.
• a_panel_without_a_recorded_place_reopens_at_its_default_place and a_recorded_place_whose_anchor_is_gone_reopens_at_its_default_place.
• a_floating_list_closed_beside_its_shown_dock_reopens_floating: a recorded floating place wins over the shown dock.
• split_frame_settings_load_as_the_dock_defaults_and_dock_layouts_round_trip, and settings_from_before_dock_columns_load_with_the_default_layouts (config).
• cargo xtask ci passes locally.

Walkthrough

Edit and Mix layouts now use dock columns for side panels. Panel opening uses dock-specific fallback locations. Saved layouts include a version, and older layouts load the new defaults while retaining other settings. Tests cover docking behavior, layout migration, and configuration recall.

Changes: Dock-column layouts and persistence

Layer / File(s)	Summary
Dock-column defaults and panel placement Cargo.toml, crates/ui-egui/src/docking.rs, crates/ui-egui/tests/it/docking_columns.rs, docs/control-protocol.md, docs/ui-parity.md, ROADMAP.md	Edit places Tracks and Clips in side docks, with MIDI below the session view. Mix places Tracks beside the Canvas. Panel opening uses an existing dock when available, or a panel-specific fallback location. Dock styling enables new dock zones. Tests and documentation describe the layouts and placement behavior.
Versioned layouts and configuration restore crates/ui-egui/src/lib.rs, crates/ui-egui/src/docking.rs, apps/soundcraft/src/config.rs, crates/ui-egui/src/menus.rs, crates/ui-egui/src/windows.rs, crates/ui-egui/tests/it/docking_columns.rs, docs/control-protocol.md, ROADMAP.md	UiState and configuration snapshots record the docking layout version. Loading layouts without a current version resets Edit and Mix docking data while retaining other settings. Configuration recall resets outdated layouts, validates both docking layouts, and preserves the current configuration list and theme.
Docking workflow validation crates/ui-egui/tests/it/docking_columns.rs, crates/ui-egui/tests/it/docking_workflows.rs, crates/ui-egui/tests/it/main.rs	Integration tests cover reopening panels with missing or stale saved locations, floating-window serialization, and panel grouping in dock columns.

Merge Risk: Low · up to bc680

The shipped dependency revision differs from the one described in the PR. Confirm the intended revision and correct the description or pin; no docking failure was established.

Security architecture risk: Low · up to bc680

The layout migration preserves unrelated preferences, and replacement layouts are validated before use. No introduced security defect was established. Risk remains low rather than minimal because the shared dependency update also reaches software-update handling, whose upstream changes could not be fully verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The direct migration affects local UI preferences and Edit/Mix workspace state. The dependency update has broader reach into native software-update handling, so its potential host-level consequences cannot be bounded to panel rendering from the available upstream evidence.

Trust Boundaries and Controls

• observed — Persisted JSON is bounded to 4 MiB before deserialization. Workspace acceptance retains upstream validation and application rules protecting the document view, bounding hidden panels, checking hidden restoration locations, and excluding Edit-only visible panels from Mix.

Resilience and Maintainability Implications

• observed — Settings saves retain strict checking of the existing source, exclusive temporary-file creation, file synchronization, and rename-based replacement. Handled write failures attempt temporary-file cleanup. These are existing containment controls, not newly added protections or proof of crash durability or concurrent-writer coordination.

Full details: Title check

Explanation

The title names the Tracks, Groups and Clips panels and full-height dock columns, which match the main change in docking.rs, the docs, and the PR objectives. It is specific about the primary change, but it does not mention the Edit and Mix default layouts, the saved-settings versioning, or the craft-ui pin, so it covers only part of the changeset.

Full details: Docstring Coverage

Explanation

Docstring coverage is 52.27% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 44 functions across 8 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Review comments at @crates/ui-egui/src/docking.rs:
- Around line 274-279: In the panel visibility flow, check whether the hidden
panel has a restorable saved location using `restores` before applying
`default_dock`; when it does, restore it with `set_visible` without an anchor so
its floating rectangle takes precedence. Add a regression test that reopens a
floating Clips panel while the End dock remains visible and verifies the
floating rectangle is restored.

Review comments at @docs/ui-parity.md:
- Line 45: Update the UI parity document’s Last reviewed and Last updated
metadata and revision history to reflect the side-panel dock-column milestone,
keeping the existing target and readiness estimate. Add the dock-column
milestone to the roadmap; do not add a gaps entry.
