CDFD Part IV: Universal Adaptive Flux Limitation

This release is the public Part IV archive for Constraint-Driven Flux Dynamics. Part IV takes the flow, constraint, responsiveness, and memory notation from the earlier CDFD releases and tests how far it can travel across Earth systems, engineered systems, socioeconomic systems, domain applications, cosmic and subatomic systems, and abstract or cognitive systems.

Manuscript Upgrade Standard

Every active Part A-G manuscript now contains:

• a paper-specific observable map for Phi, C, S, M_s, and the target outcome;
• a minimal coupled model that separates throughput, constraint accumulation, response, retained state, and cross-node coupling;
• a declared spatial, temporal, or network scale;
• a native TikZ architecture diagram;
• an evidence ladder with a load-ramp test, recovery-memory test, baseline-model comparison, and explicit falsifier;
• direct citations to CDFD Parts I-IV and the CDFD Runtime, plus the verified cross-domain reference layer appropriate to the paper family.

The synthesis paper also embeds the two release-local runtime PNGs. The reproducible manuscript transformation is maintained in Part_E_Synthesis/supplementary/major_upgrade_partiv_manuscripts.py.

Current Runtime Discoveries

The Part IV release has a current-runtime discovery pass:

• Part_E_Synthesis/supplementary/run_partiv_discovery.py imports the adjacent CDFD-Runtime and writes all artifacts inside this release tree.
• Part_E_Synthesis/outputs/universal_collapse.json stores the universal network-cascade stress test with finite-value auditing.
• Part_E_Synthesis/outputs/domain_adapter_sweep.csv and .json hold the full selected-domain adapter sweep.
• Each non-synthesis Part folder has its own outputs/domain_adapter_sweep.csv and .json slice.
• Part_E_Synthesis/figures/universal_cascade.png and Part_E_Synthesis/figures/domain_sweep_psi.png visualize the candidate cascade and adapter sweep.
• Part_E_Synthesis/outputs/partiv_discovery_summary.md records the numbers that the papers cite.

These files record what the current runtime produces. They are useful for checking the model and planning later measurement; they are not field evidence.

Review Status

These manuscripts are research/preprint materials. Part IV uses CDFD/AFL notation as a modelling language across many domains. A domain claim becomes strong only when the variables, proxies, datasets, time scales, and failure conditions are made concrete enough for another person to test.

Public CDFD Runtime

The CDFD Runtime is the reusable implementation target for CDFL, the flow-constraint-memory language used across the CDFD series. This Part IV release is a scholarly archive: paper-local scripts import selected runtime modules to reproduce diagnostics, and the archive remains cited and licensed separately from the runtime itself.
