Struct AvailabilityBlock 

pub struct AvailabilityBlock {
    pub degraded_stale: bool,
    pub kev: Option<String>,
    pub epss: Option<String>,
    pub exploitation_fusion: Option<String>,
}

Cycle-15 honesty signal block on the SDK Verdict shape. Mirrors the App wire-shape cleanlib_core::AvailabilityBlock. Option<bool>-style passthrough for degraded_stale so pre-cycle-15 payloads (without the block) deserialize cleanly.

CLEANLIB-105 App-3.2 M1/M2 additions: kev / epss / exploitation_fusion sub-fields as Option<String> (SDK-passthrough per §5 ripple discipline). String tags: "available" | "not_applicable" | "unavailable" | "degraded_stale" per cleanlib_core::FieldAvailability snake_case serde. Option on the SDK side (vs FieldAvailability non-Optional on the App side) lets pre-M1 payloads without any sub-field key deserialize cleanly to None — the SDK’s derive_status.rs treats None and "unavailable" identically (both fail the “== Some("available")” check on lines 76+).

NOTE: no skip_serializing_if on any field — this struct is bincode- serialized (positionally) by cleanlib-cli::PersistentCache, and conditional omission would corrupt the cache alignment (§CLEANLIB-104 design doc §3.M3 cache-shape note). The parent Verdict documents this invariant at the previous_verdict field. Fields that need to be omitted from the customer-facing JSON envelope are re-shaped by crate::verdict_to_envelope::verdict_to_envelope_v1 (which is the customer wire path), not by field-level serde attributes here.
