v3.7.0

[3.7.0] - 2026-07-20

Changed

• Failed MCP tool calls now expose a canonical structured result with success: false, a stable error message, and details, while retaining the first human-readable text block.
• Error results preserve content annotations, non-text content, and MCP _meta, and append exactly one compact JSON text mirror for clients that do not consume structuredContent.
• Typed output schemas for apps_list, apps_search, apps_get_details, and webhooks_verify_signature now admit the canonical error shape without changing their successful result fields.

Fixed

• Normalize direct worker errors and converted thrown errors at the central WorkerManager transport boundary so all 390 tools return consistent machine-readable failures.
• Redact sensitive error values before transport while preserving semantic identifiers and stable redaction markers across repeated normalization.
• Return canonical structured errors from the three apps_get_metadata no-version, missing-state, and missing-localization paths instead of embedding an entire JSON object inside the error string.

Compatibility

• No public MCP tool or input was added, removed, or renamed; successful tool results remain unchanged.
• Error results retain their first human-readable text block and may now include an additional compact JSON text mirror plus structuredContent; clients assuming exactly one error content block should select the first human block or consume structuredContent.
• The strict contract pin remains unchanged at 2,154 optional Apple inputs: 730 bound, 6 internally controlled, 1,010 intentionally omitted, and 408 still queued for domain review.
