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`](https://github.com/dancinlab/hexa-fusion) · [`hexa-chip`](https://github.com/dancinlab/hexa-chip) · [`hexa-mind`](https://github.com/dancinlab/hexa-mind) · the other per-domain HEXA-* standalones extracted from [`dancinlab/echoes`](https://github.com/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`](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`](AGENTS.tape) `@D g6` — implementations follow the matrix, not the other way round). Read [`SCALE.md`](SCALE.md) directly, or clone the repo:
```sh
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`](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::/` (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 |
| 4 | **Policy** | rules · norms · enforcement · accountability | written code · treaty · constitution · regulation |

> [!NOTE]
> Project governance / AI-agent harness lives in [`AGENTS.tape`](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`](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`).
