Add HP to the OAuth compatibility list (needs one vendor link)

`data/devices.json` records, for each vendor, whether their hardware can do OAuth 2.0 once Microsoft 365 stops accepting Basic authentication for SMTP AUTH in December 2026. It has 15 entries. **HP is not one of them**, and HP printers and MFPs (LaserJet, OfficeJet, PageWide) are in a very large number of offices. That gap is the whole task. ## What to send One entry, in the shape the file already uses: ```json { "vendor": "HP", "product": "printers and MFPs (LaserJet, OfficeJet, PageWide)", "status": "check-advisory", "models": ["the models the statement actually names"], "evidence": "https://link-to-the-published-hp-statement", "notes": "What breaks, which flow is supported, and which models are not promised anything." } ``` `status` is one of: `available`, `partial`, `check-advisory`, `unsupported`, `none-planned`. ## The one rule that matters **Every entry must carry an `evidence` URL pointing at something HP published.** A support page, a firmware release note, a KB article, a PDF. Not a forum post, not "my printer does this", not a guess. If HP has published nothing, that is a real and useful answer — say so in the issue and we will not invent an entry. A wrong row here sends an administrator to buy hardware they did not need, or to skip a migration they did need. `models` may be empty if the statement is vendor-wide rather than per-model. ## Where it goes Edit `data/devices.json` only. The table in `docs/DEVICE-COMPATIBILITY.md` is **generated** from it by `tools/build-device-table.py` and checked in CI, so the two cannot drift — do not edit the table by hand, it will be overwritten. Run this before opening the pull request: ```bash python tools/build-device-table.py ``` ## Why it is worth your twenty minutes This file is the only thing here that nobody else has: a hardware-confirmed record, each row backed by a link to what the vendor actually said. It is why people cite this repository. Your row is a row somebody else does not have to research at 2am with a broken scanner. Comment before you start so two people do not research the same vendor. Ask anything in the thread - a half-finished answer with a good link beats a perfect one that never arrives.
