# SuiteLink Test Fixtures

This folder stores small binary packet fixtures used by protocol codec tests.

## Source and intent

- These fixtures are based on fixed vectors already used in tests and aligned with the reverse-engineered SuiteLink dissector behavior used in this repo's design docs.
- They are intentionally minimal and validate specific assumptions, not full protocol coverage.

## Fixtures

- `handshake-ack-normal.bin`
  - Bytes: `06 00 01 00 A1 B2 C3 A5`
  - Assumption validated: normal handshake ACK frame type is `0x0001` with payload bytes preserved.
- `advise-tagid-11223344-item-A.bin`
  - Bytes: `0A 00 10 80 44 33 22 11 01 41 00 A5`
  - Assumption validated: ADVISE message type bytes are `10 80` (little-endian `0x8010`) and item encoding is UTF-16LE length-prefixed.
- `update-binary-tag-1234-true.bin`
  - Bytes: `0D 00 09 00 34 12 00 00 0A 00 C0 00 01 01 A5`
  - Assumption validated: UPDATE type bytes are `09 00` and binary value decode path maps to `true`.

## Notes

- Keep fixture count modest and focused on wire-level assumptions that are easy to regress.
- If a fixture changes, update corresponding tests and document why the protocol assumption changed.
