Readiness levels A0–A4

PlannedThe levels are defined. `davirix app check` is not implemented yet.

Each domain is graded separately. The level is not requested — it follows from which items are done.

Levels

Section titled “Levels”
What exists What the agent can do
A0 Contracts exist, no AI metadata ⛔ nothing
A1 4 query types · _label · typed errors 👁 reads — answers questions
A2 + Commands · idempotency: required · permissions ✍️ writes — result is ACKNOWLEDGED
A3 + verification on every command ✅ can say “done”
A4 + Evaluation baseline · degenerate mode 🚀 can run autonomously

What each level unlocks

Section titled “What each level unlocks”

A1 — reads

Section titled “A1 — reads”

The agent can answer questions: “How many receipts today?”, “What is running low?”

⛔ It can change nothing.

A2 — writes

Section titled “A2 — writes”

The agent records receipts and movements. But the result is ACKNOWLEDGED — “the domain replied”, not VERIFIED.

⚠ It cannot tell the user “done”. Only “sent”.

A3 — confirms

Section titled “A3 — confirms”

⚡ The critical threshold. Every command has a read-back partner and a declared predicate. Now the agent is entitled to say “receipt recorded” — because the source confirmed it.

A4 — autonomous

Section titled “A4 — autonomous”

An evaluation baseline exists: how correctly the agent behaves is measured. And every capability works in degenerate mode (one branch, one person, no approver).

⚠ A2 → A3 — where most domains stop

Section titled “⚠ A2 → A3 — where most domains stop”
verification present → A3 possible
verification absent  → STAYS at A2

This is not a technical difficulty — it is a forgotten decision:

“What proves this operation actually happened?”

Every command needs an answer. No answer means the operation is never confirmed.

Checking

Section titled “Checking”
Terminal window
$ davirix app check


A1 ✅   A2 ✅   A3 ⛔   A4 ⛔


Missing (A3):
  inventory.stock.receive    — no `verification` block
  inventory.stock.write_off  — no `verification` block


  ⚠ These two operations will NEVER be VERIFIED.


Missing (A4):
  no evaluation baseline
  inventory.stock.receive — degenerate mode untested

Degenerate mode — the A4 precondition

Section titled “Degenerate mode — the A4 precondition”

Every domain must also work for a sole trader: one branch, one person, no approver.

⛔ Breaks it ✅ Correct
“Select a branch” — mandatory With one branch, chosen automatically
“Manager must approve” — mandatory With no approver, it passes
Department structure required Optional

⚠ And when they grow — no migration. Adding a second branch must not break the same capability.

Certificate

Section titled “Certificate”

A3 and above are certified, like connectors:

{
  "domain_id": "inventory",
  "version": "2.1.0",
  "contracts_digest": "sha256:...",
  "level": "A3",
  "issued_at": "...",
  "expires_at": "..."
}

⚡ This matters for third-party domains: an inventory or HR domain written by another developer that reaches A3 can be trusted without our review.
