A restricted non-tadpole inventory

For the following ledger only, assume:

1. auxiliary fields are eliminated algebraically;

2. contractions join matching species, except for the ghost–antighost pairing;

3. a fixed normal-ordering convention removes self-contractions at a single vertex;

4. connected graphs are counted in the flat free carrier, with no added explicit quantum counterterm.

These are inventory conventions, not an interaction construction for the source-switched map.

At order $\kappa$, the relevant quantum leg types are
