For deployers

Concrete materials for getting a Mariani Village (or comparable DC-native deployment) off the ground.

Mariani Village in one paragraph

ISO 20-foot container units configured as DC-native minimal dwellings (<14 m²), deployed on host sites, repositioned annually between student occupancy (Corte, academic year) and tourist occupancy (Corsican coast, summer). No grid connection required. No licensed electrician. No CONSUEL. Total electrical cost per unit: €2,740–4,080. Commercialised through Dilorta SAS (di l'Orta — of the Orta river, Minesteggio, Corsica).

What a unit contains

Component Spec
Container ISO 20-foot, structural; SELV-certified electrical fit-out
PV array Roof-mounted, sized to seasonal load
Storage LFP battery bank, 48V SELV bus
Distribution DC-first; USB-C PD 3.1 (240W) as the human interface
AC capability Portable 700 Wh battery packet, BLE-tracked, borrowed from a shared charging station
Compute Edge inference node when the stack closes (Ophélia + Agora on-site)
Connectivity Mesh-capable, low-power radio + opportunistic WAN

The 48V SELV bus is the spine. AC is an adapter protocol at the boundary, not the substrate. USB-C PD 3.1 — operating at exactly 48V DC, up to 240W — is touch-safe, power-negotiated, and already in every user's pocket.

See the full layered analysis in dc_native_epn.md.

Regulatory navigation

The reason the unit avoids the licensed-electrician / CONSUEL path is precisely because it stays below the SELV threshold. This is engineering, not loophole exploitation: a 48V DC bus with current-limited outlets is genuinely touch-safe and falls under different regulatory frameworks than a 230V AC installation.

What we navigate for you:

  • SELV electrical codes (NF C 15-100 part 7-701 and related) — keeping the installation below the licensed-installation threshold while meeting safety standards
  • IMDG maritime framework for the LFP container packets traversing ferry routes
  • RGPD/GDPR for any installed sensing (BLE tracking, occupancy, the Atlas of Biodiversity layer if you choose to deploy it)
  • Local zoning — ISO container deployment, host-site agreements, seasonal repositioning permits

The full-stack option

A Mariani Village is wired to be a complete sovereignty site. If you want to close the stack:

  • Inseme Agora locally — assemblies, instant voting, digital gestures for resident deliberation
  • Kudocracy.Survey for consultations across the village
  • Ophélia AI mediator — running on the on-site edge inference node, powered by the on-site PV-backed battery. No vendor API call leaves the site for the mediation work.
  • Atlas of Biodiversity — if your host site has biodiversity observation potential (Corsica almost always does)

This is not required. You can run a Mariani Village as pure housing. But when you do close the stack, every layer is owned and auditable by the residents — and that's the differentiator.

Step-by-step pointers

  1. Read the habitat paper — mariani_village.md. It's the single source of truth on the deployment.
  2. Read the DC architecture — dc_native_epn.md. Needed if your site engineer is going to do anything beyond bolt-on.
  3. Read the founding EPN paper — UNCONSCIOUS_GRID.md. The theory under the practice — useful when objections come in from grid-trained engineers.
  4. For the platform side — see the inseme README. Apps, briques, multi-instance configuration, Ophélia.
  5. For the methodology — and the operational toolchain — see methodology. The corpus is governed by Cogentia Commons; the operational CLI is cogentia.js.

Your deployment as a tracked corpus

A working Mariani Village is also a small Cogentia Commons corpus. The site folder (whether on your own GitHub organization or a private Git host) carries:

  • A research/index.md listing the canonical documents for the site (BOM, site plan, regulatory dossiers, BLE asset registry).
  • A .cogentia.json registering the corpus.
  • A .cogentia/audit.jsonl accumulating one JSONL line per state-changing operation — every commissioning step, every adjustment, every objection filed by residents or by the operator.
  • A .cogentia/continuations/ directory of typed continuation records for any decision that required judgment.

You can run node cogentia.js scan against this corpus to verify that every research-grade document is anchored. You can run cogentia.js check to validate cross-references. If you contract a different firm to extend the site in two years, they get a working corpus, not a folder of PDFs.

This is optional. A Mariani Village runs perfectly well as housing alone. But when you take the corpus practice seriously, the deployment becomes contestable, auditable, and survivable across operator changes.

Cost envelope

Per-unit electrical: €2,740–4,080 (depending on PV/battery sizing). Per-unit total including container, fit-out, and tracking infrastructure varies by site.

The full-stack option (edge inference + civic platform) adds an edge compute node and software integration — quoted per project, since the integration depth varies.

How to engage

We help you with:

  • Site survey and feasibility
  • DC-native node design and bill of materials
  • Deployment supervision and operational training
  • Integration with the cognitive and civic layers if you want the full stack
  • Ongoing operations (optional)

Dilorta SAS is the commercial vehicle for the housing deployment specifically. For other deployment patterns (academic, industrial, cooperative), engagement is direct with FractaVolta.
