Agent Composer v1.3.2 – Stabilized rendered previews

SmartCloud Agent Composer 1.3.2

This release stabilizes rendered previews and adds instance-level addressing for repeated synced patterns.

Fixed

• Prevented rendered-draft and publication-approval previews from resizing the entire embedded app while content, styles, and fonts load.
• Kept approval headers and actions fixed while only the preview area scrolls.
• Deferred preview visibility until its assets and fonts are ready.
• Suppressed duplicate preview delivery and refreshed the preview resource URIs for cache invalidation.
• Fixed ambiguous overrides when the same synced pattern appears multiple times on a page or blueprint.

Added

• Stable patternInstanceId values for individual synced pattern instances.
• Override operations addressed by pattern_instance_id and field_id.
• Independent native Pattern Overrides for repeated instances of the same synced pattern.
• Slot-level allowed_patterns constraints.
• Per-pattern minimum and maximum occurrence constraints.
• Recursive synced-pattern reference, contract-version, and content-hash validation.
• Cycle and nesting-depth protection for nested synced patterns.

Upgrade notes

Restart the MCP runtime and refresh client tools and resources after installing this update so clients load the new preview resources and semantic schemas.

Existing synced-pattern instances remain readable. Composer persists a compatibility instance ID when a legacy instance is first updated.

To use allowed_patterns, pattern_occurrences, or pinned content_hash values, clone the active Config Set, update it, validate it, and activate the new version.
