1. Plugin and Platform declaration contract

• 1.1 Add safe logical file-directory/file and modeled-field contracts to plugin manifests, Platform domain/DTO projections, copying, and validation.
• 1.2 Declare SCUM configuration/log files and bounded Chinese configuration field metadata, then remove legacy SCUM overview page declarations.
• 1.3 Add focused Platform validation/projection tests for safe declaration and field ownership behavior.
• 1.4 Add a bounded redacted Platform projection for completed declared-file read results.

2. SCUM file and configuration workbench

• 2.1 Add frontend declaration contracts and resolver for the SCUM files-config default workbench and legacy route migration.
• 2.2 Build the shared-theme selection-based file list, selected-file modeled configuration form, raw config mode, unknown-field list, preview diff, and declared write dispatch experience.
• 2.3 Add declared log-file scope and Platform log stream content reading without path exposure.
• 2.4 Render the SCUM workbench embedded in server detail and keep unrelated Companion feature panels out of the file-management tab.

3. Verification

• 3.1 Add/update focused backend, plugin, route, contract, and component tests for selection state, raw mode, and embedded rendering.
• 3.2 Run strict OpenSpec validation, relevant backend/plugin/frontend checks, browser verification, and scripts/check-structure.sh.
