Multi-scale Architecture — design · build · operate · policy, from multiverse to city

multiverse · universe · galaxy · planet · country · city × design · build · operate · policy

---

hexa-scale is the multi-scale architecture standalone in the dancinlab HEXA-* family. One lattice spans six magnitudes of habitable scale — multiverse → universe → galaxy → planet → country → city — crossed with four lifecycle phases — design → build → operate → policy. The result is a 6 × 4 = 24-cell matrix, numerically matching the central n=6 identity σ(n)·φ(n) = n·τ(n) = 24 (and the Jordan totient J₂(6) = 24) at n=6.

Note

Sibling of hexa-fusion · hexa-chip · hexa-mind · the other per-domain HEXA-* standalones extracted from dancinlab/echoes. Where the other standalones drill one domain deep, hexa-scale runs the orthogonal axis — scope of habitable place, from cosmological down to civic.

At a glance

Phase ↓ \ Scale →	Multiverse	Universe	Galaxy	Planet	Country	City
Design	parameter selection (Λ · α · masses)	type-Ia inflation regime	spiral arm geometry	atmosphere / hydrosphere targets	territorial bounds + capital siting	grid topology + zoning
Build	⚠ speculative	⚠ speculative	stellar engineering (Dyson-class)	terraforming (Mars / Venus class)	infrastructure rollout (power · water · road · rail · comm)	construction · permitting · trades
Operate	⚠ speculative	⚠ speculative	civilization-level monitoring	climate stabilisation · biosphere mgmt	governance · taxation · defence · diplomacy	utilities · transit · public safety · sanitation
Policy	⚠ speculative	⚠ speculative	first-contact protocols · panspermia treaty	planetary boundaries · climate treaties · biosphere law	constitutions · treaties · trade · IP · immigration · monetary policy	building codes · zoning · noise · land use · taxation

⚠ = currently speculative — no manufactured artifact exists at this scale; cells are research-hypothesis placeholders, not engineering blueprints. See SCALE.md for the full 24-cell breakdown.

Status

• 2026-05-14 — repo bootstrap. Lattice scaffold + 24-cell matrix sketched in SCALE.md. No code yet — this standalone is design SSOT first, implementations follow.
• Reach goals (in order):
  1. Fill the 12 operational cells (planet · country · city × design · build · operate · policy) with real-world references (architects · planners · treaty texts · code books)
  2. Tighten the 4 speculative-row cells (multiverse · universe · galaxy × any phase) with ⚠ honest-caveat tagging and explicit references to mainstream cosmology / astronomy invariants
  3. Galactic-scale operate / policy cells last — they cross both the lattice-policy "external entity" rule (galaxies don't belong to dancinlab) and the "no manufactured artifact" speculative-row rule

Install

No package install yet — hexa-scale is design SSOT first (per AGENTS.tape @D g6 — implementations follow the matrix, not the other way round). Read SCALE.md directly, or clone the repo:

git clone https://github.com/dancinlab/hexa-scale && cd hexa-scale && cat SCALE.md

When downstream tooling lands (matrix linter · cross-cell citation walker · tape_to_agents_md generator hook from AGENTS.tape::@H h1), an hx install hexa-scale entry point will follow.

Run

Not a runtime — no executable. hexa-scale is a design SSOT: the 24-cell matrix is the artifact. Consume it by:

• view — read SCALE.md for the full 6-scale × 4-phase breakdown (each cell carries the ⚠ honest-caveat marker where the row is speculative)
• cite — reference cells in downstream work as hexa-scale::<scale>/<phase> (e.g. hexa-scale::city/policy for zoning / building-code work; hexa-scale::planet/operate for biosphere management)
• preserve honest-caveat — when citing a ⚠ speculative cell (multiverse / universe / galaxy rows), carry the marker forward — downstream work MUST NOT silently promote a speculative cell to an operational claim

6-scale ladder

Order	Scale	Tag	Representative invariants used by mainstream science (not n=6)
1	Multiverse	speculative	Tegmark Level I–IV · Λ-multiplicity (string landscape · 10⁵⁰⁰ vacua)
2	Universe	speculative	Λ-CDM · Hubble H₀ · Ωₘ · Ωₐ · Planck mass · spectral index nₛ
3	Galaxy	speculative	Hubble morphology · Tully-Fisher · stellar mass function · IMF
4	Planet	operational	Bond albedo · Stefan-Boltzmann · gravitational binding · plate tectonics
5	Country	operational	GDP · Gini · trade balance · constitutional separation-of-powers · UN charter
6	City	operational	population density · zoning codes · IBC / IRC / NEC / NFPA / ISO 37120

4 lifecycle phases

Order	Phase	What	Receiving artifact
1	Design	parameter selection + topology + invariant framing	drawing · spec · diagram · simulation
2	Build	physical realisation · construction · deployment	artifact (building · structure · system)
3	Operate	runtime · maintenance · adjustment · users	live system serving stakeholders

Note

Project governance / AI-agent harness lives in AGENTS.tape (.tape v1.2 grammar — §1 @V spec · §2 @I identity · §3 @L layout · §4 @D g1..g9 governance · §5 @F f1..f2 forbidden · §6 @X x1..x5 citations · §7 @N notes · §8 @H generator hooks), not in a separate AGENTS.md. The file's top ~35 lines are a self-describing grammar primer comment block, so any LLM cold-reading it (via CLAUDE.md symlink discovery) can parse the rest. Runtime handoff (decisions in flight · anomalies · planned actions) lives in SEED.tape, separated by purpose. Trade-off documented in AGENTS.tape::g9: agents.md ecosystem tooling that doesn't speak .tape yet can fall back to a generated AGENTS.md via @H h1 (tape_to_agents_md).
