# APOPHIS
|
|
|
|
Behavioral confidence for Fastify services.
|
|
|
|
APOPHIS checks whether route behavior holds across operations, states, and protocol flows.
|
|
|
|
Supported Node.js versions: 20.x and 22.x.
|
|
|
|
```bash
|
|
npm install apophis-fastify fastify @fastify/swagger
|
|
apophis init --preset safe-ci
|
|
apophis verify --profile quick --routes "POST /users"
|
|
```
|
|
|
|
## Cross-Route Failure Example
|
|
|
|
Add one behavioral contract next to a route schema. APOPHIS can verify cross-route behavior, such as whether a resource created by one route is retrievable through another.
|
|
|
|
**Route:**
|
|
|
|
```javascript
|
|
app.post('/users', {
|
|
schema: {
|
|
'x-category': 'constructor',
|
|
'x-ensures': [
|
|
// BEHAVIORAL: Creating a user must make it retrievable
|
|
'response_code(GET /users/{response_body(this).id}) == 200'
|
|
]
|
|
}
|
|
}, async (request, reply) => {
|
|
const { name } = request.body;
|
|
const id = `usr-${Date.now()}`;
|
|
reply.status(201);
|
|
return { id, name };
|
|
});
|
|
```
|
|
|
|
**APOPHIS output:**
|
|
|
|
```text
|
|
Contract violation
|
|
POST /users
|
|
Profile: quick
|
|
Seed: 42
|
|
|
|
Expected
|
|
response_code(GET /users/{response_body(this).id}) == 200
|
|
|
|
Observed
|
|
GET /users/usr-123 returned 404
|
|
|
|
Why this matters
|
|
The resource created by POST /users is not retrievable.
|
|
|
|
Replay
|
|
apophis replay --artifact reports/apophis/failure-2026-04-28T12-30-22Z.json
|
|
|
|
Next
|
|
Check the create/read consistency for POST /users and GET /users/{id}.
|
|
```
|
|
|
|
JSON Schema cannot express this relationship. APOPHIS turns it into an executable check.
|
|
|
|
## Three Modes
|
|
|
|
| Mode | Purpose | Default Environments |
|
|
|---|---|---|
|
|
| `verify` | Deterministic CI and local contract verification | local, test, CI |
|
|
| `observe` | Runtime visibility and drift detection without blocking | staging, prod |
|
|
| `qualify` | Exercise scenarios, stateful flows, and configured chaos checks before release | local, test, staging |
|
|
|
|
## Quickstart: 3 Commands
|
|
|
|
```bash
|
|
# 1. Install
|
|
npm install apophis-fastify fastify @fastify/swagger
|
|
|
|
# 2. Scaffold
|
|
apophis init --preset safe-ci
|
|
|
|
# 3. Verify
|
|
apophis verify --profile quick --routes "POST /users"
|
|
```
|
|
|
|
See [docs/getting-started.md](docs/getting-started.md) for the full walkthrough.
|
|
|
|
## Trust and Safety
|
|
|
|
- **Deterministic replay**: Every failure includes a seed and a one-command replay.
|
|
- **CI-safe default path**: `verify` is deterministic and safe for CI pipelines.
|
|
- **Production-safe observe path**: `observe` is non-blocking by default. Blocking behavior requires explicit break-glass policy.
|
|
- **Qualify path gated away from prod**: `qualify` is blocked in production by default.
|
|
- **Explicit environment boundaries**: Config rejects unknown keys and unsafe environment mixes.
|
|
|
|
## LLM-Safe
|
|
|
|
APOPHIS gives coding agents a constrained, repeatable way to encode and verify behavior:
|
|
|
|
- Official scaffolds (`safe-ci`, `llm-safe`, `platform-observe`, `protocol-lab`)
|
|
- `apophis doctor` checks for missing dependencies, malformed config, and unsafe modes
|
|
- CI policy guards catch unknown keys, unsafe environments, and missing seeds
|
|
- Generated code follows the same pattern in every repo
|
|
|
|
See [docs/llm-safe-adoption.md](docs/llm-safe-adoption.md) for templates and CI policy.
