The accelerators/ai-enablement precedent uses the literal 'platform' space
id — those credentials happen to live in the platform-owned CP accounts.
For hatchmate the credentials live in a CP account owned by the hatchmate
space, so the ref must be 'hatchmate.space:hatchmate'. Misnamed ref caused
the dispatcher's account resolver to fail with 'no active account for
AccountRef(name=hatchmate, scope=space:platform)', failing every review
task in the W4 vertical slice within seconds of dispatch.
After this lands and the next CRS sync (~5 min) refreshes the concepts
PVC, the next auto-advance fire on dfc4358c should resolve the account
and proceed through the working-repo clone with the per-org hatchmate key.
