The harbor: verticals on a managed substrate

How founder-owned products sit on the Seitiate+ business layer, with the engine, the trust layer, and the brain underneath. One picture of the architecture these pages are describing.

Verticals — founder-owned products

Each is an independent product home. The platform is neutral and horizontal — it serves whoever brings serious work through a thin contract.

Seitiate+ — the business-as-a-service middleware

The layer that turns a product surface into a business: billing, credits, access, revenue-share, legal-entity ownership, and the graduation path. The engine runs the product; Notary vouches for trust; Seitiate+ runs the business.

The destination: a founder brings real work, and it can run, take payment, and grow on shared rails. The first path is concierge onboarding; the self-serve machine comes later.

Vertical customer lifecyclelifecycle rail
  • apply → approve → subscribe → provision → credits → access
  • Keyed on (tenant, vertical) — one service, three verticals
  • Engine create-or-resolve-by-email seam #120 deployed
Billing + credits (Paddle MoR)commerce rail
  • Agent-C as merchant-of-record (Paddle wired, MoR-shaped)
  • Per-vertical pricing admin + compute / costs (PR #116)
  • Tier grants × exchange-rate peg · FIFO spend · expiry
SEIT — the substrate creditcredit model
  • Closed-loop store credit (1 SEIT = $1); not a cryptocurrency
  • Never redeemable · no inter-vertical transfer · graduation = conversion
  • Per-(tenant, vertical) isolation keeps us out of money-transmission
Opt-in shell + four rolesrole model
  • Default-empty, role-scoped nav (capability_map catalog)
  • Super-CTO · founder-owner · operator · tenant
  • Phase 1 dispatched — no placeholder UIs by construction
Owner-entity + revenue-sharegraduation path
  • owner_entity per vertical (Agent-C → founder's GE LLC)
  • Payouts to owner entities (escrow seed preserved, renamed)
  • Fee placeholder ~15% incubation / ~10% post-graduation
Graduation · Georgian entitylegal path
  • POA → form a Georgian Virtual-Zone LLC the founder owns
  • 0% corporate tax on exported IT; IP assigns to founder entity
  • Held until §11 legal/tax counsel signs off

Engine · Trust · Brain — the foundation

Three repos underneath the harbor. The engine runs the agent loop; the trust layer attests what runs; the brain holds institutional memory. None are vertical-specific — they serve whoever attaches.

Seitiate — the engine

AGPL · open-source

Harness control plane, talent registry, agent runtime. Codex (memory) · Canon (taste) · Governor (quality, two-layer) · crystallization→seity loop · Society of Thought · LLM orchestrator (9+ BYOK providers).

Elixir foundation: the forward engine core loop — session → signed memory → export → offline verify → retrieval. Integration target, not architecture hope.

Notary — the trust layer

private · IP-sensitive

Trust backbone through the entire skill lifecycle: risk classification · sandboxing · certification gauntlet · ES256 attestation machinery · provenance chain.

Also the slop filter at vertical intake — the same certification that vets a skill vets a vertical (mechanical → risk-classify → intent check → sandbox → Governor). AI authorship is fine and expected (90%+ of repos); what we filter is slop, not AI. Load-bearing when hosting third-party verticals — "we run real businesses, so what runs is vetted."

CES — the brain

coordination

Coordination, knowledge, memory, operational tooling. Memo→merge pipeline · task board · agent fleet coordination · NotebookLM institutional memory.

Agentic Contract-CI lives here: governed merge path with independent LLM review, Tier-2 hold, phone approval, audit events — the builder-side proof the substrate governs our own agents.

Serves all verticals; never the Sakme / Sensarra runtime surface.

The moat under the harbor

What travels, and what can't be copied

The seity — accumulated, non-clonable steering judgment bonded to the human, portable across runtimes. We persist the human; we don't ship the agent runtime.

Neutrality — a third party attests what a platform-owner cannot attest for itself.

The provenance stamp that travels — engine-side verification works now; neutral Notary receipts are the next trust-root ceremony. That is the flank.

The intake filter — the same Notary gauntlet that vets a skill vets a vertical before it runs. AI authorship is expected; slop is refused. The economics finish the job: every sandbox run costs the founder real SEIT credits.

The one rule

We never create verticals — founders do.

A vertical exists only when a real person owns it (their IP, their work, their revenue). Manufacture one ourselves to chase a market and we have rebuilt Sensarra — our thing to operate, not a founder's work on our platform. That is the anti-pattern. We are the harbor; we are never the fleet.
