Field case 2026-08: the display isolate invalidated the only real render endpoint; the mic held the Steam Streaming Microphone, the Speakers were blacklisted, and the capture loop re-ran the full wiring pass — three IPolicyConfig SetDefaultEndpoint writes included — every 2 s for 8+ minutes, retrying a verdict that could never change. - wiring_plan: a plan with no loopback is a typed structural verdict (Wiring::loopback_unsatisfiable + an endpoint-set fingerprint); the dead leftover() tier (byte-identical to real_hw()) becomes a real last resort that accepts ONLY the Steam Streaming Speakers, flagged loopback_last_resort — a known-silent-loopback QUALITY risk, never the cable/VoiceMeeter echo CORRECTNESS risks. excluded_from_loopback stays untouched (judge_default's mid-stream snap-back semantics). - wasapi_cap: an unsatisfiable plan errors ONCE per topology with the render inventory, per-endpoint rejection reasons and only the remedies not already taken, then parks on a cheap enumerate-and-hash poll and re-plans the instant the set changes; transient failures get a real capped exponential backoff (2 s → 60 s, reset on success or set change); a last-resort capture re-plans on any set change and promotes the 30 s zero-packet breadcrumb to warn. - audio_control: the recording default is asserted only when the plan changed or the default drifted — set_default_endpoint fires all three SetDefaultEndpoint roles unconditionally, so the 2 s loop silently stomped any operator recording-device change; the "attach one, or let the host install the Steam Streaming pair" warn (already satisfied in the field case) is replaced by the same diagnosis. Verified: 19/19 wiring_plan tests (native rustc --test and the Linux CI image via docker); both Windows files type-check and clippy clean against wasapi 0.23.0 / windows 0.62.2 for x86_64-pc-windows-msvc via an xcheck-style stub harness (the in-tree target check dies in openh264-sys2's build script on macOS, as scripts/xcheck.sh documents).
