ContentIdentity missing UUID

Error message

ContentIdentity missing UUID

What it means

The content_identity row was found but its uuid column is NULL. The proxy generator keys generated artifacts off content_uuid (stable across path changes), so a NULL uuid makes proxy generation impossible. Rows without uuid come from partial inserts, older schema versions before the column existed without backfill, or write paths that skip uuid assignment.

Solutions

1. Backfill content_identity.uuid for existing rows (generate v4 uuids) via migration
2. Audit all content_identity insert paths to confirm uuid is always set
3. Skip and re-identify affected entries so a fresh, complete identity row is written

Example fix

-- before: rows like (id, uuid=NULL, ...)
-- after: backfill migration
UPDATE content_identity SET uuid = random_blob(16) WHERE uuid IS NULL; -- sqlite example; use proper uuid generation

// Skip identities lacking a uuid and queue them for re-identification
let usable = ci.as_ref().map_or(false, |c| c.uuid.is_some());
if !usable { /* re-identify entry instead of proxying */ }

fn has_content_uuid(ci: &content_identity::Model) -> bool {
    ci.uuid.is_some()
}

let content_uuid = match ci.uuid {
    Some(u) => u,
    None => return Ok(ProcessorResult::failure("ContentIdentity missing UUID".to_string())),
};

When it happens

Trigger: Database migrated from a version where content_identity.uuid was not populated; a code path inserting content_identity without setting uuid; an interrupted update that cleared the column.

Common situations: Upgrades without uuid backfill migrations; mixed-version clients writing to one library; hand-crafted or restored rows missing the column value.
