// 02 · Failure modes

Why smart homes fail.

Consumer platforms optimize for convenience. Estates need resilience, separation, and accountability. Here is the gap — and how HouseCommand answers it.

// 08 · Safety & trust

Accountable by construction.

Every action — and every refusal — is written to a tamper-evident, hash-chained record. Nothing the platform does is unattributable. The chain below is real — SHA-256, computed in your browser. Try to get away with an edit.

Every command logged

Executed, confirmed, refused, recommended, rolled back — all recorded.

Tamper-evident chain

Each record hashes the last; any edit, insert, or deletion is detectable.

Verified actuation

Safety-critical commands confirm device state by read-back before they count as done.

Manual override preserved

Physical switches, valves, keys, and breakers always work — independent of the platform.
