# APOPHIS Setup — safe-ci preset

This project was scaffolded with \`apophis init --preset safe-ci\`.

## Quick Start

1. Ensure you have a Fastify app with @fastify/swagger registered.
2. Add behavioral contracts to your route schemas using \`x-ensures\`.
3. Run: apophis verify --profile quick

## What This Preset Does

- Runs only behavioral contracts (not schema-only routes).
- No chaos, no observe, no stateful testing.
- Safe for CI pipelines.
- Timeout: 5s per route.

## Example Behavioral Contract

Add this inside your route schema to check that a created resource is retrievable:

\`\`\`javascript
"x-ensures": [
  "response_code(GET /users/{response_body(this).id}) == 200"
]
\`\`\`

If \`apophis verify\` says "No behavioral contracts found", it means your routes have schemas but no \`x-ensures\` or \`x-requires\` clauses. Add at least one clause per route you want to verify.

## Next Steps

- Add more routes to the \`routes\` array in your profile.
- Try \`apophis init --preset platform-observe\` for production readiness.
- Try \`apophis init --preset protocol-lab\` for multi-step flows.

# APOPHIS Setup — platform-observe preset

This project was scaffolded with \`apophis init --preset platform-observe\`.

## Quick Start

1. Ensure you have a Fastify app with @fastify/swagger registered.
2. Configure your reporting sink (see environments.staging.requireSink).
3. Run: apophis observe --profile staging-observe

## What This Preset Does

- Enables observe mode for production readiness checks.
- Validates non-blocking semantics and sink configuration.
- Parallel execution for faster feedback.
- Requires sink config in staging/production.

## Safety

- Observe mode is non-blocking by default.
- Production requires explicit policy to enable blocking.
- Chaos is disabled in this preset.

## Next Steps

- Add a sink configuration to your environment policy.
- Run \`apophis doctor\` to validate the full setup.

## Quick Start

1. Ensure you have a Fastify app with @fastify/swagger registered.
2. Add behavioral contracts to your route schemas using \`x-ensures\`.
3. Run: apophis verify --profile llm-check

## What This Preset Does

- Ultra-minimal preset for LLM-generated codebases.
- 3s timeout per route (fast feedback).
- No observe, no qualify, no chaos — verify only.
- Conservative defaults to avoid surprising failures.

## Example Behavioral Contract

Add this inside your route schema to check that a created resource is retrievable:

\`\`\`javascript
"x-ensures": [
  "response_code(GET /users/{response_body(this).id}) == 200"
]
\`\`\`

If \`apophis verify\` says "No behavioral contracts found", it means your routes have schemas but no \`x-ensures\` or \`x-requires\` clauses. Add at least one clause per route you want to verify.

## Next Steps

- Add routes to the \`routes\` array once you have behavioral contracts.
- Run \`apophis doctor\` to check for missing dependencies.

# APOPHIS Setup — protocol-lab preset

This project was scaffolded with \`apophis init --preset protocol-lab\`.

## Quick Start

1. Ensure you have a Fastify app with @fastify/swagger registered.
2. Define multi-step flows in your route schemas.
3. Run: apophis qualify --profile oauth-nightly --seed 42

## What This Preset Does

- Enables qualify mode for stateful and scenario testing.
- Chaos engineering enabled (local/test only).
- Deep depth for thorough exploration.
- 15s timeout per route.

## Safety

- Chaos is blocked in production by default.
- Use \`apophis doctor\` to validate environment safety before qualifying.

## Machine Output in CI

Qualify can produce large output. In CI, use machine-readable formats and filter events:

- \`--format json\` emits a single stable JSON artifact (good for small-to-medium runs).
- \`--format ndjson\` emits one event per line (good for streaming parsers).
- Use \`--quiet\` to suppress human progress text.
- Pipe ndjson to \`jq\` or a custom filter to extract only failures:
  \`\`\`bash
  apophis qualify --profile oauth-nightly --format ndjson | jq 'select(.type == "route.failed")'
  \`\`\`
- For very large runs, consider writing artifacts to a directory and parsing the JSON file instead of stdout:
  \`\`\`bash
  apophis qualify --profile oauth-nightly --format json --artifact-dir reports/apophis
  \`\`\`

## Next Steps

- Define scenario sequences in your config.
- Add route allowlists for chaos if needed.
- Run \`apophis replay --artifact <path>\` to debug failures.
