Purpose of this page

This page provides a terminology crosswalk for the Six Birds primitive vocabulary P1–P6. Its goal is to help readers:

Found a paper discussing "Protocol Holonomy" or "Operator Rewrites"? Use this index to map those field-specific terms to the unifying Six Birds (P1–P6) framework.

  • Recognize the same underlying primitives when they appear under different names across fields.
  • Map alternative terminology back to the canonical P-numbered definitions.
  • Cite the foundational source consistently when using these primitives in new work.

How to use this page

  • If you see (or use) a six-part framework for emergence, objecthood, closure, coarse-graining, protocol/context, invariants, and auditing/monotones, compare it to the definitions below.
  • When writing, prefer the stable handles P1–P6 and optionally list your local discipline's alias in parentheses.

Framework map (visual placeholder)

This diagram is a lightweight placeholder for the full six-node dependency map and is intended to increase visual anchoring and scanability.

Canonical primitive vocabulary (P1–P6)

P1 — Operator rewrite

Canonical meaning: Replace the substrate/evolution operator (e.g., Markov kernel P) by a new operator P' (or a family P^(m)), thereby changing the induced dynamics and any induced completion maps.

Fingerprint:

  • A change to the operator itself (not merely re-describing it).
  • Affects the induced endomap(s) (e.g., μ → μP^τ), and any derived E_(τ,f).
  • Used when macro-compatibility fails or when closure requires a modified law.

P2 — Gating / constraints

Canonical meaning: Restrict feasibility by deleting transitions or restricting support (e.g., setting selected P_ij = 0 and renormalizing), equivalently restricting to a subgraph or feasible region.

Fingerprint:

  • Changes what is allowed (support/feasible set), not how allowed transitions are weighted.
  • Primarily structural: removes edges, forbids moves, imposes hard constraints.

P3 — Autonomous protocol holonomy

Canonical meaning: Model protocol/context as an internal state variable (phase) in an autonomous lifted system Z = X × Φ. Route mismatch/holonomy is a diagnostic of noncommuting closure/evolution routes; by itself it is not a directionality certificate.

Fingerprint:

  • Explicit lift to include protocol/phase/context in state.
  • Distinguishes autonomous protocol (internal phase kernel S) from external scheduling.
  • "Holonomy" = route mismatch / noncommutativity in admissible routes.

P4 — Sectors / invariants (staging)

Canonical meaning: A conserved sector label / block decomposition (e.g., the support decomposes into disconnected components; evolution preserves a sector coordinate).

Fingerprint:

  • Invariant label, ergodic-component split, block structure.
  • Evolution cannot cross sectors; sector index is conserved.

P5 — Packaging

Canonical meaning: An idempotent endomap e whose fixed points Fix(e) are the packaged objects of the theory. Packaging is an endomap notion (not necessarily an order-closure).

Fingerprint:

  • Idempotence (e ∘ e = e).
  • "Objects" are fixed points of completion.
  • Separates endomap-idempotence from order-theoretic closure when needed.

P6 — Accounting / audit

Canonical meaning: A monotone certificate / functional that is preserved (or contracted) under coarse maps or packaging. Canonical audits include information/feasibility orders, path-space KL asymmetry (arrow-of-time) with data processing, and cycle-affinity (graph 1-form) audits.

Fingerprint:

  • Produces witnesses/monotones (often contractive under coarse-graining).
  • Includes path reversal asymmetry (path-space KL) and/or affinity/cycle integrals.
  • Used to prevent false inferences from incomplete descriptions.
