braid_event_delta_gcl.py
|
||
========================
|
||
|
||
Delta-GCL + metaprobe pass over `compute_event` from
|
||
5-Applications/tools-scripts/braid/braid_photonic_emulator.py.
|
||
|
||
V3 — Mathematical improvements sourced from Lean formal model:
|
||
|
||
v1 → v2 = canonicalization (13 magic numbers → 6 named params)
|
||
v2 → v3 = Lean-derived structural improvements:
|
||
|
||
1. **Parity-of-event modulation** (GeneticCode.lean §1)
|
||
XOR(et_bits, polarity_sign) → Fc parity gate.
|
||
Purine/pyrimidine sign × canonical/wobble magnitude × parity flip.
|
||
|
||
2. **Spectral resonance echo coupling** (ShellModel.lean §4)
|
||
Echo weights scaled by spectral resonance degeneracy between
|
||
current and past event types (overlapping spectral peaks).
|
||
|
||
3. **Forward scorpion-tail echo**
|
||
Anticipatory term from known shell geometry:
|
||
the next shell-crossing position is always (k+1)², so we add a
|
||
forward-looking standing wave component.
|
||
|
||
4. **Phase formula refinement** (ShellModel.lean §5)
|
||
Discrete mass-gated interaction term combined with smooth tanh.
|
||
phase = clip(linear_term + tanh_term + mass_gate_term).
|
||
|
||
5. **Extended tail depth** (tail_depth 3 → 5)
|
||
With interaction-modulated adaptive decay: weights are
|
||
modulated by whether the past event had the same parity as current.
|
||
|
||
Goal
|
||
----
|
||
"Squeeze the lemon" on the braid event formula by applying the project's own
|
||
Delta GCL three-layer compression stack and metaprobe verification frame:
|
||
|
||
Layer 1 — Delta encoding (encode event[n+1] as diff from event[n])
|
||
Layer 2 — PTOS field dictionary (factor magic-number tables to byte indices)
|
||
Layer 3 — Variable-length codon (et ∈ {A,G,C,T} → fixed-Huffman codon)
|
||
Metaprobe gate — bit-exact round-trip + SI compression ratio vs zlib baseline
