Vigil

Preserved from the original build record. Product status and offers may have changed; the current project summary appears above.

• Problem: the occupant dot vanished after less than a second of sitting still — the tracker applied its full evidence weight on every engine tick, so a moment of quiet convinced it the house was empty. Fix: time-normalized the belief update so evidence strength depends on elapsed time, not tick rate. Any filter fed at engine rate now has to pass that rule.
• Problem: recalibration learned the occupant as the floor — the system relearned a room's baseline with a person sitting in it, then read him as absent in his own bedroom. Fix: a baseline is only accepted after the spatial signature stays genuinely still for the entire calibration window.
• Problem: even after both fixes, the dot flickered out during walks between rooms. Fix: detections now feed belief directly, stillness holds the last position instead of clearing it, and presence in another room hands the dot off rather than blanking it. Verified live: 25 of 25 samples held with zero blinks.
• Problem: the app kept 'breaking' under load — the sensing engine's frame endpoint stalled past the app's timeout, blanking the display while every node was healthy. Fix: each frame is serialized once per tick and served from cache; measured latency went from seconds to under a millisecond.
• Problem: a node stopped being seen by the system entirely, which reads to the owner as 'it isn't finding me'. Fix: nodes are told where the host is and re-adopted by an explicit sweep, and stillness now holds an occupant rather than dropping them. Both landed in the source before they landed in the owner's installed build — a gap we now treat as part of the defect, not separate from it.
• Problem: we were building two overlapping home products, and the broader one was not good enough to sell. Fix: we killed it in July 2026 and folded everything into Vigil rather than selling two half-products.
• Where we are now, honestly: a working prototype in one test house. The owner's own July 2026 assessment is that it is nowhere near finished and not yet properly connected, and we would rather print that than a launch date. It is sold as early access at $25 a month plus $25 per node, and data stays on-device throughout.
