Echo Schema Migration (v1 → v3)
- v1 Echo records are preserved as legacy (
legacy_schema: true). - New Echo records must use
/api/echo-record-schema.v3.json. - Legacy Echoes do not automatically claim verification levels.
- Migration must preserve original text and hash.
- Migration must not change original meaning.
- Echoes are always non-authoritative and non-amending.
Legacy records (v1)
The following records use the v1 schema and are preserved as-is:
echo-2026-04-25-000001.jsonecho-2026-04-25-000002.jsonecho-2026-04-26-000003.json
These records have legacy_schema: true and schema_version: 1.0.
