Plan subagent with model:sonnet reviewed Phase 0-4 with raw artifacts
(no curation per dev process). Two findings:
1. H.264 SSIM precedent framing — "mirrors fresnel iter1 exactly"
overstates the cross-host link. Two independent empirical data
points on two different rkvdec generations (RK3399 0.6431 vs
RK3588 0.6676) that converge, not a cross-verified anchor.
Reframe in iter1_close.md.
2. C7 deferral framing — "rig blocker" misframes a deliberate
scope boundary (headless-ssh by design) as a rig deficit.
Reframe in iter1_close.md.
Both findings are pure framing changes (no code/data/struct claim),
so no test-verify gate. Per empirical-over-theoretical guardrail,
adoption is direct.
Reviewer also confirmed the codec fragmentation rationale and
kernel-agent-vs-backend issue assignment as correct (no cross-codec
coupling problem).
Plan sound, proceed to Phase 6 with the two amendments applied.
