# Agent-Safe Unique Inventory specification changelog

## v0.1 — 2026-07-31

- Published the vendor-neutral field dictionary, JSON Schema, JSON-LD context,
  cross-field validator, accepted and rejected records, and self-declared
  conformance template.
- Distinguished physical-object, product/model, commercial-offer, and channel
  listing identities.
- Added optional aliases and redirect targets for merged object records.
- Documented the proposed, not-shipped relationship to a future UCP vendor
  extension projection.

Version 0.x is unstable. A removal, type change, semantic change, new required
field, or lifecycle change is breaking and requires a new minor version,
parallel versioned URLs, migration notes, and a deprecation date. Editorial
clarifications that do not change validation behavior may be patched in place
and must still be recorded here.
