DD b14: Tetrad Registry (4-element fused patterns)

Decision (TL;DR): This file is the canonical registry of every tetrad (4-element fused pattern) used on balospe.com. Tetrads follow the same formatting and propose-don’t-invent rules as trifectas, but live in their own arity-specific registry to keep the conceptual taxonomy clean.

Status: ACTIVE

Scope: Site-wide. Authoritative for which 4-element patterns are tetrads, their canonical wording, and the contexts where each is most useful.

Settled: 2026m04d24, when LLoL set up the b14–b24 range to reserve one DD per fused-pattern arity (4x through 12x), with b25 as the overview index.

Why a separate DD for tetrads?

Trifectas (3-element fused patterns) live in DD b13: Trifecta Registry. Tetrads are not trifectas: the conceptual structure is different (a 4-step cycle has different ergonomics than a 3-aspect fusion). Mixing them in one registry would blur a distinction that matters when reasoning about which pattern type fits a given context.

Both registries share the same formatting and editorial conventions:

• Single italic span across all member words, no commas, no other separators (per DD b11: Trifectas in Single-Italic-Span, No Commas; the convention is named for trifectas but generalizes to fused patterns of any arity).

• Introduction on public-facing pages follows DD b12: Ladder Pedagogy for Acronyms in Public-Facing Writing.

• Never invent inline; propose explicitly and add here only after LLoL’s go-ahead (per Proposing new tetrads below).

How tetrads relate to trifectas, IronRod, and the broader taxonomy

Tetrads (4x) are one entry in a broader taxonomy of fused patterns covering arities 3 through 12 (and possibly beyond). The taxonomy lives across DDs b13–b24, with DD b25: Fused-Pattern Taxonomy Overview as the overview index. The arity-to-DD mapping is:

• b13 — trifectas (3x)

• b14 — tetrads (4x) (this DD)

• b15–b24 — reserved for 5x through 12x (and possibly higher-arity or compound patterns); see DD b25: Fused-Pattern Taxonomy Overview for the planned mapping (subject to LLoL’s Excel-doc specification).

Many of the higher-arity fused patterns (especially 4e through 12e) echo the structure governed by the IronRod core. See the IronRod landing page (The Iron Rod) for the broader context that gives many of these patterns their semantic backbone.

The registry

Canonical wording	Frame	Scope, equivalences, and context
seed feed grow reap	life-cycle (ZION algorithm)	The 4-step self-correcting cycle that opposes the BABL algorithm. Maps to ZION: Zoning (seed), Investigating (feed), Organizing (grow), Navigating (reap). The order is fixed: seed must come first (preparing ground and sowing); feed second (tending, investigating); grow third (managing the maturing yield); reap fourth (harvesting, navigating to the next cycle, deliberate rest before the next seed). No step can be skipped without breaking the cycle. Used in: any context where a self-correcting cycle is the right model — farming, computer language design, governance, personal life, civilization-scale systems. See War of the Algorithms: BABL Math Destruction vs ZION Math Deduction for the general framework and Evolvix — A Stable Extensible Humane Computer-Language for Biology for the worked computer-language example. Glossary entry behind ZION.

Proposing new tetrads

Same protocol as trifectas (see DD b13: Trifecta Registry proposing-new-trifectas):

1. Notice the candidate when the same 4-element fusion-quality keeps showing up in different contexts.

2. Check existing tetrads first, including whether the candidate is actually a context-shifted version of seed feed grow reap.

3. Propose explicitly in conversation or in an AA file: “I notice a possible new tetrad: <word1 word2 word3 word4> — it names the fused 4-step pattern of [explanation]. Worth discussing or adding to the tetrad registry?”

4. Wait for LLoL’s go-ahead. Either pause for discussion or accept an AA task to draft the addition for review.

5. If accepted, add here. With canonical wording, frame, and the Scope, equivalences, and context column populated.

The opposite of proposing is forbidden. Do not silently use a non-registered tetrad in writing. Repetition of canonical tetrads is a feature — it lets readers see the same pattern recurring across contexts.

When to deviate

Same as DD b13: Trifecta Registry:

• Direct quotations of writing using different wording: quote verbatim.

• Pre-existing site content with non-canonical wording: migrate opportunistically when editing the same paragraph.

• LLoL’s verbatim historical writing (especially archived Zenodo descriptions): exempt unless LLoL explicitly migrates it.

Created by: Claude Opus 4.7 Max in EDEN mode at LLoL’s request (2026m04d24), to register the seed feed grow reap tetrad after the Evolvix bridge page used it and the trifecta registry (DD b13) was determined to be the wrong home (tetrads are not trifectas).
