Building BIOS Architecture

Boot Completion is the formal declaration that the BIOS has established a valid operating condition for the selected building mode.

Boot shall be considered complete only when:

BIOS integrity is verified;

authoritative configuration is loaded;

essential Core services are healthy;

required registries are available;

required Interfaces and Cartridges are discovered or accounted for;

identities are sufficiently verified;

topology is reconstructed;

configuration validation is complete;

state conflicts affecting operation are resolved or isolated;

essential dependencies are available;

required safety-system status is known;

authorized services are activated;

startup events are stored;

recovery status is confirmed.

Boot completion may result in:

full normal operation;

partial operation;

degraded operation;

maintenance mode;

emergency mode;

safe mode;

recovery mode;

boot failure.

The BIOS shall publish a Boot Status Record containing:

boot identifier;

start and completion times;

boot type;

BIOS version;

configuration version;

operating mode;

unavailable entities;

active restrictions;

faults;

services started;

required human actions.

Higher-level systems shall not infer normal building readiness from BIOS network availability alone. They shall read the authoritative Boot Status and their own service authorization.
