SRP's actor-based framing resolves the Observer-Mediator distribution-centralization tradeoff through principled judgment (actor dependency analysis determines whether distributed or centralized communication preserves responsibility boundaries), and this judgment is supported by the catalog's restraint infrastructure (Mediator's optional abstraction class enabling incremental adoption) — making the tradeoff navigable rather than merely recognized.
SRP provides the selection criterion and restraint infrastructure provides the graceful-degradation mechanism for navigating the Observer-Mediator tradeoff
