Section 3 claimed playout is pinned to exactly 1024 frames; the code now
follows the graph's Buffer::requested() quantum (pipewire_impl.rs:229-237),
with 1024 only as a fallback -- the doc described the pre-fix behavior that
caused crackle. Flagged by the 2026-06-15 Codex/GPT-5.5 review (backlog A20).
The broader ARCHITECTURE refresh (missing modules, persistent identity, signed
gossip, friends/W7, recording modes) remains under A20.
