virgili0/virgilio: technical due diligence, read from its repository
What Borehole read in virgili0/virgilio's code and history at 678bd1a: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Architecture & Codebase — including AI provenance
strongCommit messages are templated rather than written
adequate67% of commit subjects are exact repeats of another subject, and subject length varies by only 15.0 characters. A log written by someone explaining their reasoning to a future reader does not look like this. The log is therefore weak evidence of intent, whatever the code is like.

Engineering Process & SDLC Maturity
adequateTests are absent or token
adequate0 test files against 22 source files (0.0%). This does not measure whether the tests are good, only whether enough of them exist for the codebase to be changed safely by someone who did not write it — which is exactly the situation after an acquisition.
| 0 test files / 22 source files |
Nothing in the history is tagged as a release
adequateAcross 6.6 years of history there is not one tag. There may still be a deployment process, but this repository holds no record of what shipped when — which is the record a buyer needs to reconstruct an incident or a regression after the fact.
| 0 tags across 1,373 commits and 2408 days |
Almost no process scaffolding exists in the repository
adequateOf five ordinary markers — CI workflows, CODEOWNERS, a pull-request template, pre-commit hooks, contribution guidance — 1 is present: CI workflows. Branch protection itself is a GitHub setting rather than a file, so this is a reading of proxies and not of the rules themselves. What it does establish is that the process is not written down anywhere a new engineer would find it.
| 1 of 5 markers present across 164 tracked files |
Product & Engineering Maturity
not assessableChange keeps returning to the same few files
adequateFive files out of 586 absorb 25% of all file-level change. Concentration like this is where debt is usually being serviced rather than repaid: the same code is reopened because it is load-bearing, fragile, or both. A repository cannot tell you which — that is a conversation with the team.

Security & Reliability Posture
adequateNone of the standard security guard rails are configured
adequateThere is no disclosure policy, no automated dependency updates, no named code owners and no pre-commit configuration. None of these is load-bearing on its own. Their collective absence says that security posture here is whatever the current team happens to remember to do, which is not a posture that survives the team changing.

The licence is CC-BY-NC-SA-4.0: source available, not open source
adequateLICENSE grants CC-BY-NC-SA-4.0: source available, not open source; commercial use not allowed. The reading comes from the licence's own title and clauses. Whether the terms fit the buyer's intended use, and whether any paid licence transfers with the code, is a question for counsel and the licensor.
LICENSE:1 — 437 lines, CC-BY-NC-SA-4.0 |
Relicensed: GPL-3.0 → CC-BY-NC-SA-4.0 (2020-05-03)
adequateThe root licence changed 1 time(s). The latest terms restrict what users, hosts or a buyer may do in ways the earlier ones did not. Code taken under the old terms stays under them, so both matter in diligence.
LICENSE.md — GPL-3.0 from 2019-03-24 |
LICENSE — CC-BY-NC-SA-4.0 from 2020-05-03 |
