/**
 * 17-silence-blank-handling.test.mjs
 *
 * Tests the silence / blank handling (留白) mechanism.
 * Validates that the system gracefully handles:
 * - No intervention preferred
 * - Silence decision enumeration (none/no_card/defer/intentional_silence)
 * - Defer with deadline requirement
 * - Interrupt with justification requirement
 * - Attention budget exceeded → automatic silence
 * - Graceful degradation for missing capabilities
 * - Empty run artifacts rejection
 * - No-data-safe default behavior
 *
 * Validates:
 * - silencePolicy contract compliance
 * - defaultNoCardPolicy
 * - Graceful fallback for undefined behavior
