docs: correct the lamassu-machine licensing boundary to commit c0b69d1

Browse source 
The provenance section claimed v8.1.5 was the last fully-open release.
GitHub history says otherwise: a9234d124d ("chore: add LICENSE",
2023-09-19) removed UNLICENSE and added the proprietary Appendix A SLA,
and the v8.1.5 tag (2023-09-21) already ships it. The true public-domain
boundary is that commit's parent, c0b69d1 ("chore: v8.6.0-beta.9") —
which is further along than 8.1.5 feature-wise.

lamassu-server's own boundary is unverified; flagged in the doc.

## Provenance + legal status
The HAL drivers (validators / dispensers / printers) and the cash-flow state machine derive from Lamassu Industries AG's open-source `lamassu-machine` and `lamassu-server` repositories, **only up to v8.1.5** — the last release published under a fully-open license. Lamassu transitioned to a proprietary, source-available license (their custom "Appendix A SLA") on 2024-01-26 and gated v8.1.6+ behind a paid OSA subscription.
The HAL drivers (validators / dispensers / printers) and the cash-flow state machine derive from Lamassu Industries AG's `lamassu-machine` repository, **only up to commit `c0b69d1ed196d396c5f057478c2ea290babd58ab`** ("chore: v8.6.0-beta.9", 2023-09-19) — the last commit published into the public domain (`UNLICENSE` in tree). The very next commit, `a9234d124d` ("chore: add LICENSE (#1019)", 2023-09-19), removed `UNLICENSE` and added Lamassu's proprietary "Appendix A SLA". **The `v8.1.5` tag (2023-09-21) already ships the Appendix A license** — the previously documented "8.1.5 is the open boundary" was wrong (verified against GitHub history 2026-07-04). Note the public-domain boundary sits on the 8.6-beta line, which is *further along* than 8.1.5 feature-wise.
**Hard rule when working in this repo:** do not pull, port, or copy code from lamassu-machine / lamassu-server at v8.1.6 or later. If a HAL bug fix or feature exists upstream past 8.1.5, either (a) reimplement from protocol docs / hardware specs without looking at v8.1.6+ source, or (b) raise the question with the maintainer first. The 8.1.5 tree is fair game; everything after is licensed code we have no rights to.
**Hard rule when working in this repo:** do not pull, port, or copy lamassu-machine code from `a9234d124d` or later (which includes every 8.1.5+ tag). Reference only `c0b69d1` or earlier. If a HAL bug fix or feature exists upstream past that commit, either (a) reimplement from protocol docs / hardware specs without looking at the licensed source, or (b) raise the question with the maintainer first. To fetch the open tree safely: `git fetch --depth 1 origin c0b69d1ed196d396c5f057478c2ea290babd58ab` — never check out a tag.
The `lamassu-server` boundary has not been re-verified against its own history and may differ — check its license-change commit before referencing it.
