Fixture Manifests

Status: draft | Updated 2026-07-06 | Applies to: AMPG and AMPB compatibility checks

AMPG writes deterministic fixture manifests so AMPB can verify that generated site variants route to the expected browser transport and profile.

Output

ampg build writes one manifest per site:

<site.outputs.root>/ampg-fixture-manifest.json

The manifest contains public route expectations only:

• site id, domain, and canonical URL.
• enabled protocol fixtures.
• protocol renderer and relative output path.
• route URL for AMPB checks.
• expected AMPB transport and profile.
• declared interaction tier, identity adapter, payment adapter, realtime flag, and public exposure flag.
• optional route-group metadata for configured public route policies.

It must not contain private host inventory, hidden-service keys, tunnel keys, credentials, or deployment notes.

Commands

python3 -m ampg --config examples/wownero.gateway.toml build
python3 -m ampg --config examples/wownero.gateway.toml manifest

build emits the manifest after writing protocol outputs. manifest rewrites only the manifest and does not rebuild protocol outputs.

Address Status

Some transports may not have final public addresses when a fixture is generated. In those cases AMPG uses route-valid placeholders such as http://wownero.onion/ so AMPB can still verify transport selection without contacting the network.

Interaction Policy

Fixture interaction policy defaults to:

{
  "tier": "static",
  "identity": "none",
  "payments": "none",
  "realtime": false,
  "public_allowed": true
}

Protocol-level options can declare the base fixture policy that AMPB should check.

When [[site.interactions.route]] entries are configured, AMPG emits additional fixtures for public route groups. Routes with tier = "internal", public_allowed = false, or a match covered by deny_routes are not emitted.

Routes imported from site.interactions.route_manifest are treated the same way as inline TOML routes.

AMPG also omits route fixtures whose interaction tier exceeds the protocol target's max_tier. When max_tier is not configured, AMPG uses the transport capability defaults from the generated interaction capability matrix.
