Organismal candidate attractor · a form that holds itself

Growth & Repair

A body-plan grows to a target shape — then, cut it, and watch it regrow the missing part.

Kernel role Organismal · developmental — a candidate attractor (BEP §3.4). An authored design claim, not a measurement.
Stack No. A single panel, not a vertical layering of dependent layers.
Substrate Synchronous (α = 1). Temporal order is partly supplied by the clock rather than produced by the system.
The four sovereignty conditions (SOV §7.2) — what this panel supplies, not how it scored
  • exercised 1 · Recursion lock. Morphology is a maintained attractor (BEP §3.4): the body grows to a target shape and, when a chunk is cut away, the still-connected tissue regrows to target while an isolated fragment withers — you can watch identity restored or lost.
  • exercised 2 · Internal recurcline persistence. The match-to-target either recovers after damage or the fragment fails to regenerate. Caveat: The update runs synchronously at α=1, and the morphogen field is computed globally each step, so part of both the temporal and positional order is supplied.
  • exercised 3 · Boundary retention. Unlike the other panels, a boundary IS modeled here: the connected-tissue rule maintains a form against damage. Tissue disconnected from the organizer dies, so the body's distinction from empty space is actively restored.
  • supplied 4 · Maintenance-bearing continuation. The organizer cell always survives and is the free signal source, and growth into the target radius is at an authored rate with no modeled inflow — so the maintenance of form is bought with an authored organizer, not paid by the structure.

No sovereignty verdict is claimed here or anywhere in this gallery. The Sovereign column is empty, and that emptiness is the honest reading: no panel here has been shown to produce its own order.

The molecular and population panels asked whether a flow could hold a basin. This one asks a different question: can a shape hold itself? A form grows outward from an organizer until it matches a target body-plan, then stops. The real test is what happens when you damage it: a self-holding form treats its shape as an attractor — disturb it and it returns. This is morphological regeneration, the planaria trick, made runnable, and it maps to BEP (§3.4): identity sustained while the boundary is restored.

The target is authored — watch the return, not the shape

The target body-plan is supplied by the modeler: an organizer emits a signal, and cells grow or die to match how far that signal says the boundary should reach. That authored target is the supplied structure, shown plainly. What is worth watching is not that it reaches the shape — it is whether it returns to the shape after damage, and how much damage it can take before the form fails to come back (a rupture, β).

Draw on the canvas to cut away tissue, or use the buttons. Small wounds heal; a large enough excision can push the form past recovery. No sovereignty verdict is claimed — only the observable: did the form regenerate, or rupture?

at target form — holding
Synchronous substrate (α = 1); the target is authored. The organizer's signal and the target radius are supplied — shown, not hidden. What you can trust is the run: after a cut, does the boundary return to the target, or fail? Space is kept honest on Duncan(√5). No sovereignty verdict is claimed — that is gated.
