Command ids are SolveCraft's own: 173 ids that were another product's internal command ids become dotted, lower-case ids (<area>.<thing>[.<variant>]: solid.extrude, sketch.rectangle.two_point, sheet.flange, joint.drive, ...), in the registry, toolbar, dialogs, shortcuts, palette, control channel, MCP, examples, scenarios and docs

The old ids live only in crates/engine/src/legacy_ids.rs (the legacy migration table): find_command maps them, so old scripts, recipes and control calls keep working, and saved shortcuts, recent and pinned commands are migrated on load (designs store no command ids). Parity maps the observed catalog ids to ours through xtask/data/fusion-ids.tsv. The agent rule now reads: our own dotted id, never another product's. Cargo.toml's repository points at github.com/bherbruck/solvecraft.
