/* ══════════════════════════ MODULE I: Lattice Kernel ══════════════════════
 *  The reduction.
 *
 *  phi_lattice[4096] is not just the entropy seed — it IS the security state.
 *  Three primitive operations cover every cryptographic OS need:
 *
 *    lk_read(ctx, out, n)    derive n bytes for a named context (HKDF domain)
 *    lk_advance()            ratchet: mix OS entropy + step → irreversible
 *    lk_commit(sig, pub)     PhiSign(H(lattice)) = PCR-equivalent attestation
 *
 *  Higher-level OS primitives are pure composition:
 *    lk_seal / lk_unseal     sealed storage  (phi_stream AEAD, key from lattice)
 *    lk_proc_context(pid)    per-process entropy isolation
 *
 *  OS model (lattice as hardware security register):
 *    boot       lk_advance() per stage    → lattice encodes full boot history
 *    interrupt  lk_advance() on each IRQ  → entropy evolves with system activity
 *    syscall    lk_read("cap-N", ...)     → per-capability sealed token
 *    process    lk_proc_context(pid)      → isolated per-process entropy stream
 *    storage    lk_seal(data)             → TPM-equivalent sealed blob
 *    audit      lk_commit()              → attested PCR chain
 *
 *  No key store.  No PKI.  No key manager daemon.
 *  The lattice state IS the security state.  Wu-wei: no forcing.

 *   3. Entropy generation rate           (IEEE-754 → bytes)
 *   4. Prime-lattice pipeline            (phi_filter over seeded slots)
 *   5. Scheduler derive latency          (slot → sched param, all 10)
 *   6. Seed folding rate                 (XOR-fold 64 slots)
 *   7. Full re-seed cycle                (50-step Weyl on N=4096)
 *   8. Slot derive throughput            (derive all 50 slots)
 *   9. Container apply latency           (docker exec roundtrip)

 *    RDTSC      : current TSC tick count  (crystal × PLL multiplier)

 *
 *  Phi-resonance SIMD compute with hardware-entropy crystal seeding.
 *  This is the "fire" — phi-Weyl + resonance at hardware peak throughput.
 *
 *  What "quantum" means here:
 *    4-wide double    :  __m256d processes 4 amplitudes simultaneously
 *    8-wide float     :  __m256  processes 8 phase scores simultaneously
 *    FMA              :  phi*(v+1) = fmadd(v, phi, phi)  — 1 instruction,
 *                        no intermediate rounding, full Skylake FP precision
 *    Crystal-aligned  :  inner loops of 117 = 1 crystal oscillation period
 *    Analog cascade   :  float32 analog sieve → only survivors go to MR
 *
 *  Skylake peak (measured TSC = 2808 MHz):
 *    4× double FMA:  4 × 2 FLOPS × 2 units = 16 FLOPS/cycle → 44.9 GFLOPS
 *    8× float  FMA:  8 × 2 FLOPS × 2 units = 32 FLOPS/cycle → 89.9 GFLOPS
 *    L1 bandwidth:  2 × 256-bit loads/cycle = 179 GB/s
 *    Lattice sweep:  32 KB / 179 GB/s = 179 ns per full pass
