Disposition	Reframed
GGA basis	Blueprint pp. 6, 17 (GGA-Requirement-Register)
Replaced or carried by	GS10-staged, GS17-staged
Still open	GQ04-staged
What changes	Each applicant’s pitch is separate and isolated from other applicants. Separate discussion threads stay a Proposed carry-forward.

The 1.3 text below is kept verbatim as history. Where the disposition is Reframed, Superseded or Parked it is not the GGA oracle; use the replacing scenario. A Parked scenario has no GGA feedback and stays a Proposed carry-forward. The status stays Not executed. Register: Scenario-Dispositions.

Given

A-B and A-C contain distinct canary messages, EOI terms and next actions.

When

B and C exchange messages with A, then request each other’s IDs, lists, counts and links.

Then / oracle

A can work both authorised threads; B cannot read, infer or change C’s private engagement and vice versa. Shared public opportunity content remains visible. Neither respondent list exposes competitor identity/activity.

Evidence required

Canary absence across response bodies, counts, snippets, notifications and errors; positive counterparty evidence.

Decision dependency (verbatim)

Q08: DG metadata allowlist; private respondent counts are not public by default.
