What

testing/suites/v2g/: a software-in-the-loop suite where an EVerest EVSE and an EVerest EV (Josev) complete DC charging sessions over a veth pair, for ISO 15118-2 and DIN 70121, each recorded on the link.

• just test-v2g runs it (Linux Docker; the EVerest image is pinned by digest, about 15.6 GB on disk, so no CI job yet).
• just v2g-record records captures/{iso2-dc,din-dc}.pcapng again, each with a .messages.csv sidecar: frame number, direction and EVerest's own message name per V2GTP frame.

Tests

Test	Asserts
test_session[iso2], [din]	protocol selected; SessionSetup through SessionStop in order with a CurrentDemand loop; FIN, no RST
test_ev_unplug_mid_current_demand	session ends in CurrentDemand with no stop sequence
test_isolation_fault	CableCheck fails, no PreCharge, no CurrentDemand
test_capture_fixture	the committed captures and sidecars pass the same link checks; needs only tshark

Local run on this branch: 6 passed in 132 s (Docker Desktop, arm64).

Notes

• SLAC is simulated in process (no HomePlug frames on the link): real SLAC over a veth needs a modem to answer CM_SET_KEY.
• EXI is not decoded by the suite; frames are named by the EVSE's record of them, matched on bytes. Requests only: this EVerest release logs responses with the request's header.
• Not verified on a native amd64 Linux host.
