Acceptance now names the discovery fact (console_fact_get fact key err,
returning the effective err channel name) so the clause is testable like
G-007's named facts. Detail file additions: "every -console site" is
satisfied at the module's documented resolution choke points
(console_spec_resolve, hybrid_console_spec, opt_console_* helpers,
spec_to_channelpair, shared PUNKARGS fragments) rather than by per-site
audit; the two consumer-shaped acceptance clauses' division of labour is
stated (internal diagnostics migration = first consumer, external consumer
= public emit form); G-001 backends wanting a distinct diagnostic stream
must set err explicitly (default merges into out); and
previous_stty_state_stderr stays as-is (stty-state restoration, orthogonal
to diagnostic routing).
