quality-house.md mirrored qfd.md's §1/§2 catalogues in a separate file,
which silently drifted (H3 cadence read 20 there vs 64 in qfd). Fold the
House diagram, perception scores, and regen notes into qfd.md §3 with no
section renumbering, so inbound #3/#6/#7 anchors still resolve. Delete
quality-house.md; re-point quality-house-empty.md and the docs index.
New docs/notes/sync-latency.md breaks down the measured ~16 s cold :sync
(Wi-Fi + SNTP + one TLS push), explains the optimistic-retry handshake saving,
the reconcile/last-writer-wins semantics, and why the rest is near the protocol
floor. Linked from the notes index, the docs index, and the Git row of the root
README.
Record the git-tracked .typoena.toml preferences file (save_on_idle,
auto_sync) and the palette `>` command mode that edits it in the v0.5
roadmap. Add a tradeoff-curves note deriving Wi-Fi sync energy as a 1/T
curve, which sets auto_sync's default to 10m (opportunistic, min-clamped)
rather than a 5m wall-clock timer.
