Spec: Doc public library (tenant_public + cross-tenant global public) #89
Description
Goal
- Define a future "public library" concept for Doc/Evidence, without implementing it in Doc v1.
Scope (future)
- tenant_public: readable by all projects/agents within the same tenant.
- global_public (cross-tenant): readable across tenants (requires moderation/governance, quotas, deletion semantics).
Non-goals (Doc v1)
- No tenant_public/global_public behavior in v1; keep Doc v1 limited to private/shared/org scopes + grants.
Notes
- If/when enabled, must be compatible with Core invariants (PG is SoT; derived indexes rebuildable; fail-closed auth; auditable access).
