Remove the fixed pseudorange start offset, preserve per-PRN navigation assistance across RF loss and power cycles, and seed coherent navigation measurement phase on reacquisition. Add full LNAV almanac visibility scheduling, power-safe QSPI journaling, RF-domain reset isolation, and PPS Gray CDC hardening with Linux, sanitizer, RTL, and end-to-end coverage.
Wait for every navigation-ready tracking channel in a GPS epoch, remove unlocked channels without a timeout, and keep late joins for the next epoch. Reset PLIC ownership during warm initialization and extend Linux synthetic, integrity, and fake-MMIO regression coverage.
