Glossary

Each term below is used in the theory in a specific, often non-standard sense. v0.6 vocabulary throughout. When in doubt while reading, return here.

TermDefinition
Interaction The single substance. Atomic 6-tuple: A, B, local space, local time, mark, Propagation. Comes into being only when B becomes aware of A's mark.
Pole One of the two ends of an interaction (A = mark-leaver, B = aware). Intrinsic to the interaction, not a free-standing thing.
Awareness The primitive non-interactional act by which B brings the interaction into being. Not detection. Not itself an interaction.
Mark A bit set by A and delivered to B by Propagation. Always 1 when actual (existence vs void). Moved, never copied. Not computed by the interaction. Its entire content: "agent B — agent A exists." All complexity lives in the time-and-space variance of many marks, never in any mark's content. For Mass, primitive — the simplest fact of distinction.
Source The one agent occupying the A-pole of every Mass-interaction (v0.14) — and it is the One Interaction's own A-pole: the Big Bang's mark-leaver is the mark-leaver at every leaf. A leaf cannot supply its own mark-leaver; the Source fills that slot for all of them — it sets every floor bit. One Source ⇒ one world. Within our universe it is never a B-pole; it may be the B-pole of an interaction outside our universe — outside scope.
Event (formalism) One completed interaction, as the clean-room mathematics names it: an element of the actual set E. Candidates not yet completed live in the potential Ω and do not (yet) exist. The same thing as "interaction," in math clothing — the word is borrowed from the mathematics of causal orders.
Propagation The internal process of an interaction: the carrying of the mark from A to B — down A's substrate to Mass, across the floor, up B's substrate. Its medium is the subtree of sub-interactions. Always inside an interaction; has no existence outside one. Not a Form, not a Protocol, not a tier. (Replaced "Computation" in v0.13 — the mark is carried, not computed.)
Mass The atomic, leaf-level interaction. Has no sub-interactions. Lacks a local agent A — its A is the Source; its primitive mark is the Source's bit. The substance out of which all higher interactions are composed. The origin of all interactions.
One Interaction The universe. Root of the tree. Its interior contains everything we can observe. Its mark is forever hidden from us by construction.
Local spacetime The space and time intrinsic to a particular interaction. There is no universal spacetime; what we experience as "the" spacetime is the interior of the One Interaction.
Agent A bundle of pole-positions tied together by shared awareness. Not a separate primitive — derivative of interactions.
Form A constituted agent — ever-changing, not fixed; categorized by its Protocol-profile (the Protocols it manifests). Form_N is the agent that emerges when many alike Form_{N−1} interact according to a Protocol_N. Recursive all the way down to Mass.
Protocol The regular pattern between alike Forms, established via their structurally-isomorphic interactions with lower-complexity forms. Emergent-over its substrate (uses it as medium but carries structure of its own). Genealogically built layer by layer; primitive at level 1 (between Mass-interactions). Matches the everyday meaning of the word.
Solidification Achievement of a self-reinforcing autopoietic loop. The Form becomes a stable attractor against the substrate's dissolution-tendency.
Crystallization The process by which the structurally-isomorphic lower-level patterns of alike Forms stabilize into a regular medium, and by which the higher-order Protocol regularities emerge over that medium. Two coupled aspects: substrate stabilization and emergence of Protocol-level structure.
Alikeness Structural isomorphism of lower-level interaction patterns. Same kind of structure performing the same kind of role — not literal identity, not mere overlap. Recursively defined for Forms above level 1; primitive at level 1.
Action The way a Form maintains its own existence. Autopoiesis enacted. A filter over the interaction-potential. Not evidence of a Form's existence — it is the existence.
Interaction-potential The space of possible interactions. The "abyss of randomness" out of which Forms emerge.
Decay The substrate's default tendency toward disorder and data loss. Active everywhere. What every Form is working against.
Emergence The substrate's countervailing tendency: the spontaneous crystallization of patterns from high-density chaotic interactions. The source of all Forms.
Hub The structural form of every agent: one downward axis (its own internal Propagation, decipherable) and many upward axes (the parent interactions it participates in, indecipherable from inside).
Asymmetric Epistemic Principle An agent can decipher its sub-interactions but never fully decipher the parent interactions in which it participates. Downward science is possible; upward decipherment is not.
Cross-level interaction asymmetry (v0.3) An agent interacts with lower-complexity Forms (via lower-level protocols), interacts with same-level Forms (via the level's Protocol), but cannot interact with higher-complexity Forms in which it participates — only be part of them. Down: interaction. Up: constitution.
Time (v0.5) The order of succession of a parent interaction's children's completions. Read upward. One-dimensional — each interaction has exactly one awareness-pole, so a parent reads exactly one completion-sequence.
Space (v0.5) The order of coexistence of a parent's children — the room granted for them to be many at once. Allocated downward.
Spacetime (v0.5) The populated interior of an interaction. Space and time are two readings of it — coexistence versus succession. The split is a choice of reading-angle.
Interaction-throughput (the budget) (v0.5) The fixed total an agent spends, split between completion (→ time) and propagation (→ space). Its conserved magnitude is c.
Mass (v0.5) Ongoing/bound interaction — the completion-component of an agent's budget. Refines, not replaces, the leaf-interaction sense of Mass: both are "interaction as substance." Masslessness is pure propagation (interaction in transit), travelling at c.
Reference frame (v0.5) A parent interaction's interior. All motion and all space/time splits are relative to it; there is no master frame.
c (light speed) (v0.5) The exchange rate between the succession-axis (time) and the coexistence-axis (space); the conserved magnitude of the interaction-throughput budget.
Energy (v0.6) The rate at which a Form completes the interactions that constitute and maintain it — the dynamic measure of bound interaction (mass is the static measure). Equivalently, the rate of Action.
Rest energy (v0.6) The maintenance-rate a Form must sustain merely to persist against decay; the irreducible cost of existing. Equals mc².
Momentum (v0.6) The propagation-share (space-component) of an agent's interaction-throughput, as energy is the completion-share (time-component).
