(a) documented: deleting a vacuum marker erases its server trail at once
and a re-added marker starts from scratch (VACUUM.md + both USER-GUIDEs).
(b) smoothVacPath reports dropped non-finite segments — one console warn
per call with the count — instead of hiding the whole trail silently on a
broken calibration matrix. (c) room climate (#317) now reaches legacy
markers whose exported config carries an ABSENT area key rather than an
explicit null: `== null` where the placement is decided. (d) the armed
furniture preview follows Shift without mouse movement — window
keydown/keyup listeners live exactly as long as the palette is armed,
detached at every palette teardown. (e) only the primary mouse button
places decor/furniture: a right or middle click with an armed tool is a
no-op, touch/pen untouched. (f) a device whose registry entities were ALL
deliberately disabled by the user no longer glows as an alive controller —
the #318 entityless-active rule now requires a genuinely empty roster.
(g) furniture-pack author corrected to Sergey Matyunin (Сергей Матюнин)
per the owner's decision — LICENSE.md, README.md, pack.json,
docs/FURNITURE.md, the provenance check in generate-furniture-assets and
its unit; the source archive bytes are unchanged and the README notes the
romanisation fix.
Proofs: units for (b)/(c)/(f) including the #318 regression pair; new
smoke_furniture_polish for (d)/(e) with listener add/remove counters and
both mouse buttons; five registry mutants, one per code change.
Issue: #369
