Placing a palette component no longer edits <schema> straight away. The kit is noted as pending, its manifest is compiled so the box can be painted, and the status bar says the kit will be declared on save. The <schema> block is then reconciled when the file is written, in the one place that can report the whole kit list the file will carry, with each kit's version and checksum. What a kit's manifest depends on counts as used too, transitively, so placing a component can bring in more than one entry: hvac pulls in types, ontrolPion pulls in ontrolPlatform. New Kits > Manage Kits... dialog lists every kit in three groups -- needed by the app, declared but unused, and merely installed -- with the pinned build, the newest installed build, and an Action dropdown of every build a kit ships. The tick means the schema declares the kit: grey and fixed for kits the app needs, unticked to remove, ticked to add at the newest build. "Upgrade all kits to latest version" moves every declared kit; "Update kits" applies the ticks and the Action column, additions and removals included. Every schema change is applied as a batch, then verified: a missing manifest or a component type that stops resolving reverts the whole block and reports why, and a kit the app needs cannot be removed. Changes are one undo step, which recompiles the slot registry in both directions since a repin can change a component's slots. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
