Module retention 

Retention items and availability (spec 004, 3.1.2, 3.1.6 and 3.1.7).

The host owns storage, access checks, expiry and erasure. A retention item declares what the host kept of one document and until when; Rustev validates the declaration and, at a caller-supplied time, the bytes. A digest proves integrity relative to expected bytes, never truth, authorization or producer identity.

Structs

RetentionItem

One retained document, as the host declares it.

Enums

Availability

What a retained input is at replay time. Only available contributes to reproduction; none of the others is a pass.

Retention

How the bytes were kept. Every mode has an expiry.

Constants

DEFAULT_METADATA_LIFETIME_MS

A new bundle’s metadata lifetime unless the host chooses otherwise.

MAX_BUNDLE_LIFETIME_MS

The hard maximum lifetime of a bundle, from its creation. Extending it requires an amendment; the host may enforce a shorter cap.
