00 Autonomous Systems Engineering

A rigorous systems model in hours, not months.

seaane turns a specification into a complete, machine-checked SysML v2 model — the full ISO 15288 lifecycle, run by 32 specialized agents. No MBSE department, no six-figure tools, no coverage taken on faith.

01 The problem

A rigorous systems model costs months — and a team most groups don't have.

Model-based systems engineering is how complex programs stay coherent, but the rigor is gated behind scarce specialists, heavyweight tools, and quarters of manual modeling. So the teams who need it most — engineers already at capacity, program leads without a systems-engineering function — wait on the bottleneck, or skip the model and lose the traceability that keeps a build honest.

Cost & time

Months, not hours

A real MBSE model is quarters of specialist effort and six-figure tool seats — out of reach for most programs, and every early team.

Scarcity

The expertise is rare

Fluent SysML modelers are hard to hire and already overloaded, so the model becomes the bottleneck the whole program waits on.

Access

Rigor is locked away

Program leads and domain experts understand the system but can't build the model — so teams without an SE function go without that rigor entirely.

02 The thesis

Everything goes in the model.

One SysML v2 model is the single source of truth. Prose, decks and diagrams are generated from it — never maintained beside it.

Any decision, requirement, structure, behavior, analysis or test is recorded as SysML v2 textual notation. If it isn't in the model, it doesn't exist. That one rule is what makes coverage something a machine can check instead of something a reviewer has to trust.

· Why SysML v2

Open standard

Not a vendor's format

SysML v2 is an open OMG standard — the model isn't trapped in one company's tool, licence, or roadmap. You own it outright.

Plain text

Diff it, review it, version it

Textual notation lives in git like code — no six-figure seats, no proprietary file to open it. Every change is reviewable.

Portable

It outlives the tooling

Any conformant tool can read it, and so can any engineer. The model is an asset you keep, not a rental.

03 How it works

A fleet of agents on a shared model, behind one gate.

Agents never call each other. All coordination happens through shared, typed state — so the interface between agents is diffable, versioned, and checkable.

The contract

Every agent is the same box

A uniform ICOM contract: fixed controls and mechanisms, only inputs and outputs vary. Adding the 33rd agent is configuration, not code.

The data plane

A blackboard, not a mesh

One writer per package; explicit imports; the model is the interface. Worst-case failure is one bad file, caught before hand-off.

The gate

A commit barrier

Nothing is "done" until the linter passes. The gate turns "looks complete" into "is checked complete" — a build failure, not a review comment.

04 Traceability

A stable ID is a foreign key. The chain either closes, or it fails.

Every cross-package link lives in one file, so coverage is auditable in a single pass. A requirement that doesn't reach both a design part and a verification case is a gap the build reports by name.

05 The economics

The cheapest place to fix a requirement is where it's written.

Requirements defects caught at integration or in the field are the classic driver of systems-engineering cost overruns — far more expensive to correct than at the source. seaane moves detection to the moment a gap is introduced, and collapses three drifting documents into one model you never maintain by hand.

Industry range for correcting a requirements defect downstream versus at the source.

Escaped requirements

Nothing ships without a verification link — the gate won't allow it.

Source of truth

Prose and decks are generated, not hand-kept — one artifact to maintain, not three.

24/7

Engineering throughput

The fleet evolves and re-verifies the model on a schedule, between review gates.

// cost-escalation figures are an industry range, not a client-specific projection

06 Deploy & govern

Runs on your cloud — or in an enclave.

Provider-agnostic transport, least privilege by construction, and a versioned model store so every accepted version is auditable and recoverable.

Any backend

Your choice of LLM backend — a hosted API, your own cloud, or an on-prem, air-gapped model. No lock-in.

Least privilege

Capability is granted per agent, not to the fleet — only 7 of 32 agents can execute a shell.

Autonomous or on-demand

Scrape a spec, model it, then evolve and optimize it on a schedule — each run gated before it lands.

Versioned model store

Every accepted model is written to a versioned bucket with an immutable timestamped snapshot per run.

Human review gate

Autonomy iterates in the store; a pull request is still what reaches your repository. The gate to production stays human.

Auditable by design

Every change is a git commit attributable to one agent, paired with a structured report.
