Flip §A live health TUI pane to pending-live-QA (fd67a6c), register the QA
gate in §F, add docs/qa/QA-health-tui-pane.md. Note that §4 health-checks is
now feature-complete in code (3 probes + pane) — retire as a unit once QA passes.
Synthesize the five 2026-06-13 design specs and session memory into a
single outstanding-work list. Header rules: resolved items move to
RETRO.md; every finished feature gets a live-QA plan before it counts as
resolved. Add docs/qa/TEMPLATE.md as the observable-evidence QA form.
