## Description

Tracker for OQ-05 (`deferred(scope)`): sha256 support policy. Not
actionable work — tracks whether ecosystem need arrives (a real
client/repo requiring sha256, or upstream gix sha256 maturity worth
testing). On trigger: mark completed, OQ-05 transitions to `open`.

## Work

None by default.

## Verification

- OQ-05 status matches `docs/architecture/open-questions.md`.

## Out of scope

- sha256 implementation.
