Latched Hyperprior

latched-hyperprior

The Latched Hyperprior Hypothesis (LHH) (Johnson 2023): if a vascular contraction is held long enough it engages the latch-bridge common to smooth muscle — myosin latches to actin and holds tension without ongoing ATP. This durably freezes the nearby circuit, isolating it from conscious experience and global updating: a committed hyperprior. The latch releases once the prediction it stabilizes is resolved. This is the −1 / coplay leg of the vasocomputation timescale triad: the durable commit.

Use When

• Modeling durable commitments / "holding tension in the body" (latches persist seconds → years)
• Trauma / PTSD as a hyperprior cemented against incoming data
• Latch spirals: latch → ↓blood flow → ↓energy → can't release (migraine, cluster headache, neuropathy)
• The cross-substrate view of a latch (below) — the single fixed point read mechanically, bioelectrically, immunologically, sheaf-theoretically

What is a latch? — one fixed point, four substrates

A latch is not four lookalikes; it is one self-stabilizing fixed point of the body's distributed inference, read at four levels at once:

• Bioelectric (Levin): bistable Vmem holds its own setpoint with no ongoing instruction (cf. the planarian two-head: a stable bioelectric memory surviving regeneration, genome unchanged). Gap junctions are the restriction maps of the body's sheaf: open → local sections glue → H¹=0 → latches cycle; closed → local section isolated → H¹≠0 → a held prior that can't be corrected by neighbors. Pushed to also recruit proliferation, this is Levin's cancer = cells that bioelectrically disconnect from the morphogenetic field — a latch that learned to copy itself.
• Löb fixed point: □(commitment) → commitment. The latch is the contact locus = fixed-point set of the body's □(self-model) — the oldies contact manifold = fixed-point set of □(Nash) at somatic scale.
• Release is active: unlatching costs activation energy (Johnson) = immune resolution programs (resolvins/lipoxins) actively terminate, not passive decay. Sauna + cold plunge, attention into the tissue, and psychedelics force the clench–release cycle.

GF(3) Balanced Triad

compressive-vasomotion (+1) ⊗ vascular-clamp (0) ⊗ latched-hyperprior (−1) = 0 (mod 3)

Skill Trit: −1 (Coplay / commit — the consolidated hold; a sticky latch is a nogood-H¹ to repair, distinct from content-H¹ legitimately-held disagreement to preserve).

Honesty markers

Grounded: latch-bridge ATP-free hold; Vmem bistability/hysteresis; gap-junction uncoupling isolating domains; cancer-as-bioelectric-disconnection (Levin); active inflammation-resolution. Structural correspondence (not asserted biology): latch = Löb fixed point = H¹ of the body's justification sheaf; gap junctions = restriction maps.

Concomitant Skills

Current literature (2024–2026)

• Hai & Murphy (1988); Dillon et al. (1981); Rembold (2004) — the four-state latch; detachment is rate-limiting (slow k7), high force at low phosphorylation; an "ultraslow" PKC latch holds even longer.
• Pezzulo, LaPalme, Durant & Levin (2019) — planarian two-headed form is a stable bioelectric attractor, rewritten by gap-junction blockade (octanol), reset by the ion-pump blocker SCH28080 — permanence with a wild-type genome.
• Levin (2014, Mol Biol Cell) — Vmem as epigenetic switch; cancer = loss of gap-junction coupling (bioelectric disconnection).
• van der Kolk (2014); Schleip (fascial plasticity) — sustained load "freezes" a defensive posture; collagen cross-linking gives the weeks–years tail.
• Capdeville-Atkinson (1994); FHM2 Ca²⁺-sensitization (2018) — cluster-headache temporal arteries show spontaneous rhythmic VSMC contraction; MYPT1 = a genetic latch-bias.
• Key sharpening: a latch is kinetic, not thermodynamic — a fixed point defended by a rate-limited exit barrier (hard to leave, not hard to hold). MLCK↑ / MLCP↓ is the commit knob; gap-junction uncoupling = isolation from global updating, literally.
• Hook / falsifier: heat (sauna) and Ca²⁺/Mg²⁺ shifts favour release; octanol flips the attractor and SCH28080 reset falsifies "permanent."
• Grounded: latch kinetics, Vmem/GJ bistability, fascial cross-linking, VSMC hypercontractility. Speculative (structural analogy): the sheaf-H¹ / Löb-fixed-point layer — no cohomology is computed; keep as content-H¹ hypothesis, not asserted biology.

Counterfactual structure

A latch is a held counterfactual — a prediction kept against reality until action makes it true (or it is abandoned). This gives LHH a causal-inference reading:

• Treatment effect: latch-above-baseline = E[tension | do(hold)] − E[tension | never] — the causal effect of the contraction (factual vs counterfactual), already computed in vasocompute.bb.
• Latch spiral = do(ischemia) (Pearl rung 3): ATP depletion blocks cross-bridge detachment (rigor → k7→0), so the latch cannot release. Counterfactual harm = tension(ischemic) − tension(factual) = "had flow been restored, this tissue would have released." The Mongolian gerbil (incomplete circle of Willis) is the do(occlude) preparation that measures it (CA1 delayed neuronal death).
• Overhypothesis (Kemp & Tenenbaum): a latch stores not a datum but a learned prior over priors — the computational content of a hyperprior.
• Resolvability = the repair criterion: a latch whose counterfactual can be made true is a nogood-H¹ to repair (release on resolution); one in an uncontrollable domain (counterfactual unsatisfiable) is content-H¹ — the irreducible suffering term (TUAI failure mode 2).

See chirho-counterfactual for the rigorous SCM version of the do(k7→0) query.
