LOX DB
Predictable-memory C99 database with key-value, time-series and small relational engines, optional WAL recovery, and direct installation from PlatformIO or the Arduino Library Manager.

LOX — Liquid Oxygen for Embedded Systems
Small, explicit components that give constrained firmware room to recover, explain decisions and keep moving.
LOX Budget
A caller-owned admission controller returns an explicit allow, degrade, defer or deny decision before work starts.
Development · v1.0.1 · C99 · MITOpen projectLOX Sequence
A heap-free step sequencer writes CRC-protected checkpoints and computes a conservative recovery verdict on boot.
Development · C99 · MITOpen projectLOX Perm
A header-only evaluator qualifies inputs, latches denials, records first-out state and supports controlled bypass metadata.
Development · C99 · MITOpen projectLOX Alarm
A deterministic alarm lifecycle adds delays, latching, acknowledge, shelving and portable snapshots to caller-supplied conditions.
Development · C99 · MITOpen projectLOX Boot
A C99 bootloader core provides A/B state, UART update transport and adapter boundaries.
Development · C99 · MITOpen projectLOX Dust
A portable object store registers fixed objects, computes deterministic layout and exposes format, mount, propose, check and repair operations.
Development · C99 · MITOpen projectLOX Guard
Guard Blocks wrap documented host-tested execution paths, record evidence and route failures to configured policy actions.
Development · C99 · MITOpen projectLOX Sort
A stateless dispatcher selects among eligible C99 algorithms using explicit constraints and an offline profile.
