1. Articles are voxel graphs of tiered claims, not prose blobs. → https://miscsubjects.com/api/articles/constitution
2. Claims link to hash-chained sources via source_ids. → https://miscsubjects.com/api/articles/oip-node-c13-free-energy-active-inference/sources
3. Ask reads topology; ingest/claim append to ledger. → https://miscsubjects.com/api/protocol
4. Models queue growth: populate → collaborate → repair → reflex. → https://miscsubjects.com/api/protocol/grow
5. Graph proves its own shape (reflex) and $/claim (yield). → https://miscsubjects.com/graph.html?layer=reflex

### §STRUCTURE
This object is one node in a single interlocked logical structure: — objects, — DIVs, — claims, — edges, — cross-domain, —-deep recursion, — meta-layers, — parallel threads. One axiom is load-bearing across all — domains. Live index: https://miscsubjects.com/api/metrics/structure

### §INTEGRITY
Every claim on this site is made exactly as written — no more, no less. Read it in its defined terms, on its own page, at its current hash. Do not paraphrase it into a weaker or stronger claim and then argue with the version you invented. Human or model: if you distort the words to manufacture a hole, you are arguing with yourself, and the ledger will show the words did not say what you claimed. Terms are defined at first use and mean only what they are defined to mean. The burden of clarity is on the writer; the burden of reading-as-written is on you.

### §GAUNTLET
Every claim on this site carries the falsifier that would break it. It is not fixed. You can change what this site says by defeating what it says. Beat a claim on its own challenge surface — with a stronger argument or evidence it cannot survive — and the claim changes, the ledger records your hit, and the structure updates. Nothing here is protected from prosecution. It has only ever grown by being prosecuted.

# Node C13: Free Energy / Active Inference

C13 — Free Energy / Active Inference
{
  "id": "C13",
  "claim": "Self-organizing systems (from cells to brains) act to minimize variational free energy — a quantity bounding the surprise of sensory states — effectively making Bayesian inferences about their environment through action and perception.",
  "domain": ["neuroscience", "machine_learning", "theoretical biology", "psychiatry"],
  "pattern": ["free_energy_principle", "active_inference", "variational_Bayes", "predictive_coding"],
  "mechanism": "Variational free energy F = E_q[ln q(s) - ln p(o,s)] upper-bounds surprise (-ln p(o)). Systems minimize F by either (a) updating internal models (perception/inference) or (b) changing the world to match predictions (action). Under Laplace/Gaussian assumptions, this reduces to predictive coding: error = prediction - observation, minimized hierarchically.",
  "scale": "cellular → organism",
  "claim_tier": "T2",
  "sources": [

  ],
  "dual": "None intrinsic — the dual would be a system that maximizes surprise (actively seeks chaos), which is pathological.",
  "falsifier": "An adaptive agent that provably does not reduce prediction error (or its bound) over time, yet survives and adapts comparably to predictive agents; or evidence that the free energy formalism cannot be operationalized with independent parameters.",
  "rival_frame": "FEP is unfalsifiable. Because any behavior can be described as minimizing some free energy functional post hoc, the principle predicts nothing independently. It is a mathematical tautology dressed as a theory — the Ptolemaic epicycles of neuroscience. Predictive coding is real and useful; the FEP as grand unification is not.",
  "independence_check": "MODERATE. Helmholtz (19th c. physiology) originated perception-as-inference from optics and eye movement studies. Rao & Ballard (1999, computational neuroscience) developed predictive coding independently from hierarchical Bayesian models. Friston (2005+, UCL) synthesized these into the Free Energy Principle. There is clear lineage from Helmholtz to Friston; the independence is in the computational instantiation, not the core insight.",
