Para Mensch Commons

para-mensch-commons

A single entry point for the universal Para-mensch atom — the categorical-cybernetics learner block whose three closures are Play (forward), Witness (residual/conservation), Coplay (parameter feedback) — and the constellation of skills that instantiate, compose, or audit it.

The mensch (observer / world-bearer / interviewer / scheduler / experimenter) rides exclusively in the parameter slot P. Substrate runs through the data slot S → T. The audit lives at the residual port M with a GF(3) trit. Conservation = ∑ trit ≡ 0 (mod 3). Three closures, one fixed-point.

Three diagrammatic rewrite operations are the three traces of this open block. Para(Optic(𝓒)) provides the home; contextads (Capucci–Gavranović 2024) provide the 2-categorical composition; the random_walk_verifier style of yb-translator certifies hexagon coassociativity.

Domain instantiations (the 23 disjoint substrates)

Each of the 23 rows is one EM-coalgebra of the same 2-comonad (contextad). The "no canonical" rows are graph-holes — places where the corpus has not yet manifested the parable. They are H¹ obstructions in the Čech audit of bartons-law-sheaf.

Cross-family threading

• Hedges chain rule = the inhabitant of Para(Lens) whose backward pass is the transpose-Jacobian. Skills: parametrised-optics-cybernetics ↔ reverse-derivative-coordinator ↔ dialectica.
• Open-games ⊗ Bayesian via Stoch: open-games × monad-bayes-asi-interleave = probabilistic learner with explicit prior in P.
• Conservation ⊣ Tambara closure: lyapunov-function ⊣ gf3-conservation-oracle. The Tambara module is the configurable choice of permitted losses.
• Yang-Baxter coherence ↔ yb-translator hexagon check: yang-baxter-integrability instantiates the 2-cell that yb-translator/scripts/random_walk_verifier.clj empirically verifies on the corpus.
• Coplay ⊗ Coplay via Kan: composing two backward passes is kan-extensions of reverse-derivative-coordinator — left-Kan along the parameter substitution.

yb-translator parable (per its own format)

CONCEPT: Para-mensch atom
BIOLOGY: chaperone-substrate complex with feedback-regulated ATPase
ONTOLOGY: GO — protein folding chaperone (GO:0044183), ATPase activity (GO:0016887),
          regulation of catalytic activity (GO:0050790)
EXAMPLE: HSP70 binds nascent polypeptide (S), couples ATP hydrolysis (P parameter),
         emits folded protein (T); Hsp40/Hop/Bag1 control parameter feedback (◁);
         3'-5' proofreading on cofactor identity emits the trit (◇)

The 23 domains above each unfold under Δ to a distinct ontology branch, but every unfolding satisfies the same coalgebra coherence — the surprising-effectiveness theorem.

Use when

• Picking a categorical home for a new learning task
• Auditing an existing pipeline's conservation predicate
• Threading control / Lyapunov / Birkhoff arguments across substrate boundaries
• Locating the right hub for a new skill that "runs a process on bearers"
• Establishing src↔dest bidirectional traversal at the contextad level (after repl-commons does it at the runtime level)

Atlas

• REPL atlas hub: repl-commons (runtime-substrate level)
• ACP client atlas: see acp-clients-landscape memory
• Para-mensch atlas hub: this skill (categorical-substrate level)

Three nested atlases at three levels of abstraction. Same Δ/ε shape; different 𝓒 underneath.

CT lattice (category-theory orphan capture)

43 skills in the pure category-theory lattice are wired through para-mensch-commons as their natural home -- the Para(Optic) atom IS the categorical context for these constructions.
