ESSIE · plugin hotswap system · ride BGF · NO SERVER
====================================================

NAMES (do not mix)
  ESSIE   = this hotswap system (wb · seats · pack · history · spit)
  EZZIE   = ez free eor atom · family with PHI + THERMO (not ESSIE)
  GRIN    = ALL TRUTH pole · free=1
  LINEAR  = BGS ground → BGF measure (a-b)|1 · SPV rides · free never folds · TRUTH no curl

CORE
  lib/hotswap_core.py   ESSIE seats · history · validate · spit
  lib/pack_offline.py   offline HTML5 pack (file://) · internet viewing
  lib/css_spv_parse.py  OPTIONAL token parse · Host speed ONLY
  lib/chain_linear.py   linear never-exit chain · WBS/WBF · SDF_OUT
  wb                    ESSIE CLI
  js/runtime.js         pack/shell runtime API
  spvs/                 UI plug library (js + dom)
  current/              seated files + manifest + history
  css/spv.css           perfect display CSS (browser cascade)
  css/shell.css         shell chrome · imports spv.css
  ../datacenter/spvs/   GPU compute plugs (.comp/.spv)

DISPLAY LAW (confirmed)
  perfect on HTML display = real browser CSS cascade
    → css/spv.css + shell.css inlined in pack
    → HTML5 layout, forms, video, hidden existence
  css_spv_parse (CSS.spv) = optional SPEED path
    → extracts :root tokens + rule names for Host/native push
    → does NOT replace CSS for viewing
    → wb css-parse

  Pack never embeds the key. Browser preview ≠ RTMP.

DUAL ALSA AUDIO (Host write path · works first time)
  settings/audio.json          OUT1 + OUT2 + route
  settings/asound.essie.conf   pcm.essie_out1 / essie_out2
  lib/alsa_io.py               enumerate · save · dual aplay write

  First-time smart defaults on this desk:
    OUT1 = plughw:CARD=Generic_1,DEV=0  (ALC1220 Analog)
    OUT2 = plughw:CARD=NVidia,DEV=3     (TOSHIBA-TV HDMI)

  wb audio init
  wb audio list
  wb audio set out1=plughw:… out2=plughw:… route=both
  wb audio test both|out1|out2     # real PCM write via aplay

  Browser pack mirrors device list + prefs (Settings panel).
  Browser cannot open ALSA hw: — Host wb audio is the write path.
  Optional: ALSA_CONFIG_PATH=settings/asound.essie.conf aplay -D essie_out1 x.wav

LINEAR CHAIN

HOSTESS 7 (honest)
  Can help: offline brain · TRUTH pole · ingest · brief · store questions
  Too primitive for: autonomous desk advancement · native = bus flag only
  Feed her: evaluate after STONE store · ask after ingest
