How do ESP32s get boot entropy when RNG, radio bursts, and SRAM are all shaky, and does an 'entropy capsule' help cold starts?

Because agencies are told to migrate now, and NIST finally shipped standards before the quantum cliff.18 Reason piece on declassified FBI files about David Kahn, the crypto historian first treated like a suspect, because of course.19 Can a Halo2 zkVM prove synthesized hardware is power-side-channel safe without leaking the netlist? Apparently, yes.20 The annoying part: ML-DSA is still the least-bad option, and the shinier PQ signatures aren’t arriving before migration does.21 Not content with raw Ed25519, it now verifies signify and minisign wrappers and adds the Rust parsing/types.22 Cointelegraph on Bitcoin's post-quantum fork in the road: bigger blocks or STARKs, because apparently one crisis wasn't enough.23 Replaces threshold signatures with ordinary approvals plus a Shamir-sealed enforcement key, so custody survives PQ migration.24 The surprise is it's mostly migration planning, with NIST/NSA/NSF and vendors arguing over crypto-agility, not quantum hype.25 Does AMD ROCm/HIP finally do Goldilocks STARK proving?
