# Synthetic network fixture

`synthetic_history_network.json` is the committed end-to-end packet fixture for
the exporter test suite. It contains UDP payloads for Permanent Board and Arc
history requests/responses, plus isolated protocol edge cases.

The fixture is safe to publish:

- endpoints use the RFC 5737 documentation ranges `192.0.2.0/24` and
  `198.51.100.0/24`;
- packet and history timestamps are deterministic synthetic values;
- it contains no game user UID, account/session data, cookies, tokens, or raw
  capture metadata;
- the test suite checks every payload with the UID extractor before accepting
  it.

Tests load the fixture through helpers in `tests/support.py`. The `replay`
scenario is fed through `LiveHistorySession`; `protocol_sample` packets cover
points gifts, chase rewards, batched pages, and bit-packed responses.

Do not replace this file with a real `.pcap`, `.flows`, or exported account
history. Add new cases by constructing the smallest relevant payload, replacing
all timestamps and endpoints, and extending the privacy assertions.
