## Description

Tracker for OQ-06 (`deferred(scope)`): registry/metadata backing store.
This task is not actionable work — it tracks whether the blocking
condition has arrived: concrete metadata-scale requirements (repo count,
metadata fields beyond id/root/visibility/ACL scope, alkcall-hub
integration scope). When they exist, mark completed; OQ-06 transitions to
`open`.

## Work

None by default. On trigger: set OQ-06 to `open` and schedule the backing
decision session.

## Verification

- OQ-06 status matches `docs/architecture/open-questions.md`.

## Out of scope

- Choosing the backing store.

## Summary

> Filled on completion.
