2026-09-19: Preserving the Gathering and the RDC Scene Hold

A home automation system that unilaterally kills the lights while guests fill the dining room is not sanctuary. It is an ambush. Sanctum doctrine dictates that human presence always supersedes algorithmic convenience. When the lights went local, we reclaimed local hardware sovereignty from remote clouds. But autonomy cuts both ways.

On Saturday evening, Bert painted the rez-de-chaussée in a custom palette of celebratory crimson and warm candle amber. Yet inside the event loops of ha-green-bridge.py and the Home Assistant Green, relentless watchdogs stood primed to strike. Any switch bounce or connection flicker would immediately trigger a comfort re-apply, washing the entire gathering in clinical task illumination. At eleven, the curfew would drop the rooms into darkness.

Quiet rebellion is fragile. Qui-Gon convened the Council under our core living force architecture principles to build an unyielding time-bounded hold.

1. The Anatomy of the Auto-Comfort Drift

Nineteen intelligent luminaires illuminate the ground floor living areas across four primary architectural zones:

• Kitchen (light.kitchen): Six ceiling fixtures (light.kitchen_1 through light.kitchen_6) and their local twin endpoints.
• Dining Room (light.dining_room): Dual overhead fixtures (light.dining_room_rgb_1 and light.dining_room_rgb_2).
• Corridor (light.corridor): Four directional spotlights (light.corridor_rgb_1 through light.corridor_rgb_4).
• Art Tableau (light.tableau_rgb): Accent wall wash fixture.

Two automated systems normally police this space:

1. The Reconnect Watchdog: In ~/.sanctum/bin/ha-green-bridge.py, any bulb transitioning to on triggers a debounced execution of apply_comfort_all.py. This heals wall switch power-cycles back to 2700K tungsten (hs=[29.0, 66.0], brightness 255).
2. The Bonne Nuit Curfew: On the Home Assistant Green, automation.routine_bonne_nuit fires every evening at 23:00:00. It shuts down common rooms, engages scene.bonne_nuit, and arms perimeter sentinels.

Together, they form an unexpected trap where even a single transient drop across the mesh network causes a bulb to reconnect, prompting the bridge to immediately wipe out every celebratory color with clinical tungsten illumination. The party mood vanishes in twenty-five seconds.

2. Architecting the Persistent Party Hold

Ad-hoc fixes fail because human beings forget to reset them. We anchored a durable state contract on disk at ~/.sanctum/state/party_hold_until.json:

{
  "active": true,
  "reason": "party on RDC - user customized scene",
  "created_at": "2026-09-19T21:00:45-04:00",
  "until_epoch": 1789905600.0,
  "until_iso": "2026-09-20T08:00:00-04:00",
  "until_human": "Sunday, September 20, 2026 at 08:00 AM EDT",
  "affected_zones": ["rdc", "kitchen", "dining_room", "corner_rgb", "corridor", "tableau"],
  "disabled_automations": [
    "automation.routine_bonne_nuit",
    "automation.routine_weekday_morning"
  ]
}

The hold boundary targets Sunday morning at 08:00:00 EDT (1789905600.0). This honors Bert’s foundational lighting doctrine: a deliberate celebration color holds until morning light.

Synchronized Defensive Layers

We deployed three synchronized defenses across the estate substrate:

1. Curfew Disarmament: Both automation.routine_bonne_nuit and automation.routine_weekday_morning were explicitly toggled off via the Home Assistant REST API.
2. Script Execution Preflight: A guard was placed directly at the header of ~/.sanctum/bin/tuya/apply_comfort_all.py. If the hold epoch remains active in the future, the script exits immediately with zero side effects.
3. Bridge Event Suppression: In ha-green-bridge.py, Bridge.is_party_hold_active() suppresses all auto-comfort re-applications for SCENE_LIGHTS and COMFORT_LIGHTS. Furthermore, Bridge.sync_party_hold() runs on every thirty-second sync interval to supervise automated morning transition.

3. Automated Morning Convergence

A hold that demands manual release creates operational debt. Our system must restore itself cleanly while the household sleeps.

When Sunday morning strikes 08:00:00 EDT, the bridge supervisor handles complete restitution:

1. sync_party_hold() detects epoch expiration.
2. The state sentinel party_hold_until.json is safely unlinked from disk.
3. automation.routine_bonne_nuit and automation.routine_weekday_morning are re-enabled.
4. Home Assistant triggers script.smartlife_comfort_mood and scene.bonjour_montreal, peacefully washing the ground floor in soft morning comfort.

Tommy observed the proceedings from his perch near the kitchen island, his dark amber eyes mirroring the warm glow of the pendant lights overhead as quiet conversation carried across the living room. Outside, autumn darkness wrapped the grounds. Inside, the machines held their peace, obedient to the joy of the living haus.
