List feature families or return field, type, function-body, source-file, deployment-artifact, or Custom CSS evidence extracted from ICC Plus.

List official viewer classes with source evidence and project-specific escaped row, choice, and selectable-addon selectors.

Statically analyze stored or candidate CSS for syntax, selector specificity, official classes, project ids, inline-style conflicts, and external assets.

Replace, append, prepend, or clear the official project customCSS field with revision protection, dry-run support, and integrated validation.

Read the generated JSON Schema summary, one definition, or the complete project schema.

Create an in-memory project from current upstream defaults. Nothing is written until save is called.

Open a project JSON file from ICCPLUS_WORKSPACE into an isolated revisioned session.

List in-memory project sessions, revisions, dirty state, and compact summaries.

Return revision, dirty state, summary, Custom CSS analysis, validation counts, and optionally project JSON.

Read one or more RFC 6901 JSON Pointers without returning the complete project; preserves exact CSS, HTML, JS, and unknown fields while redacting embedded assets by default.

Search rows, choices, addons, scores, requirements, points, groups, designs, words, variables, sound effects, and categories.

Create any modeled ICC Plus entity with current project defaults, optional overrides, automatic ids, and normalized memberships.

Deep-merge fields into one entity and optionally unset fields. ID changes can rewrite all modeled references.

Duplicate an entity and nested content with fresh ids; optionally remap references within the clone.

Move an entity within its current ordered container and repair stored indices.

Delete one entity. The default policy rejects deletions that create dangling references.

Atomically apply RFC 6902 JSON Patch operations for any current or future ICC Plus field.

Migrate legacy shapes, generate missing ids, repair indices/parents, and rebuild reciprocal group/design memberships.

Run generated structural schema checks plus ids, references, requirements, memberships, cycles, Custom CSS, and export invariants.

Evaluate an entity or supplied requirement tree using ICC Plus operator semantics and return an explainable trace.

Return a row, choice, addon, score, requirement, or feature entity as reusable JSON.

Import a fragment through the same parent/default/normalization layer used for normal entity creation.

Set any string field from a workspace file as a data URL, or from an external/data URL, using an exact JSON Pointer.

Atomically save project JSON inside ICCPLUS_WORKSPACE after optional strict validation.

Package the project into an official web/local viewer template, applying loading config and optional deduplicated image separation.

Undo or redo one in-memory mutation while keeping revision conflict protection.

Close an in-memory session. Unsaved sessions require force=true.
