# Revision Plan

## Blocking changes

- Add explicit rejection behavior for unauthenticated portable trust assertions.
- Strengthen stale-data handling for expired assertions.
- Add a clearer abstract field or token for trust statement model identification.
- Clarify whether negative portable assertions require evidence reference, explanation code, or one of the two.

## High-value improvements

- Add one compact example assertion and one multi-issuer conflict example.
- Clarify revocation versus supersession.
- Decide whether trust events are first-class interoperable objects in v1 or primarily internal feeder records.
- Tighten abstract and terminology wording.

## Deferred items

- cross-issuer aggregation algorithms
- global reputation semantics
- large shared registries
- mandatory numeric scoring

## Draft order for next iteration

1. Tighten Sections 4 through 8 around portable assertion conformance.
2. Add explicit model identification and stale-data rules.
3. Add negative-assertion handling rules and examples.
4. Revisit Security, Privacy, IANA, and References for final consistency.
