DecisionsQ08

Given

DG has approved membership/operational tools and admin MFA; B/C private canaries exist.

When

DG opens routine metadata views and attempts private-body routes; exercise any expressly approved support-access path.

Then / oracle

Candidate routine DG allowlist: opaque record/event IDs, approved event/state labels and timestamps only. Exclude bodies, terms, decline reasons and contact data. Company/participant identifiers await Q08. Private-body routes deny by default. Any approved support exception is scoped, time-limited, authorised and audited; otherwise disabled.

Evidence required

Field-by-field metadata allow/deny tests; synthetic bodies/terms/reasons/contacts absent; support grant/revoke audit if approved.

Decision dependency (verbatim)

Q08: final metadata/identifier allowlist and support authoriser/scope/expiry. Candidate is not approved production data access.
