A choice of RPL-1.5 or a commercial licence since 2025-07-02: open source; offering it over a network counts as distributing it, so a hosted product's changes must be published; deploying it, even for internal business use, obliges publishing the source of any changes and extensions.
1 of 6 assessable dimensions carries significant findings, 1 is adequate and 3 are strong. 8 findings, each with its evidence: the commit, path and lines it rests on, or, when something is missing, what was looked for. One dimension cannot be assessed without an acquirer.

03 · significant findings · ratings ↑Bus factor 1: recent work is concentrated in one contributor
significant findingsIn the last 24 months, one contributor authored three-quarters or more of 125 non-merge commits among 6 authors; across all history, a quarter or more of 3,494. This is the single most expensive thing to discover after closing, and the repository cannot tell you whether that person is part of the transaction.

Respond to this finding
Your response is published beside the finding, not instead of it. A finding you can argue with is the point — and a wrong one is calibration data we want.
An owner's response is removed only when it is unlawful, impersonates someone, publishes personal data or a credential, or is not about the finding. Disagreeing with the report is never a reason. To report a response, or to reach us about one, write to takedown@borehole.dev.
The contributor who wrote a quarter or more of this has not committed here for more than a year
adequateOne person authored a quarter or more of 3,494 commits and has not committed here for more than a year, while the repository has kept moving. The concentration figure alone would not show this. Whoever is changing this code now is not the person who wrote most of it, which is the situation an acquirer is usually told they are avoiding. The history shows only that no commits of theirs landed here, not why.

The next contributor after the top one has not committed here for more than a year
adequateThe #2 contributor of the last three years (less than a quarter of the commits) has not committed here for more than a year, while the repository is still active. These are the people a buyer assumes would step up if the top contributor stopped. The history shows only that no commits of theirs landed here, not why.

Product & Engineering Maturity
04 · strong · ratings ↑Effort is shifting from building to rewriting
adequateDeleted lines per line added rose from 0.86 to 1.20 between the first and second halves of this history. Rework is normal and often healthy, but a rising ratio means an increasing share of the team's time is spent replacing code that already exists rather than building what does not. Whether that is deliberate repayment or churn is a question for the team.
A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

The build runs third-party code it does not pin
adequate3 third-party CI actions are referenced by a tag or branch rather than a commit, so they run whatever that tag points to on the day. Tags have been moved to malicious commits in real supply-chain attacks, and a piped script is whatever the server returns that minute. Pinning to a commit is the fix, and it is small.

The licence is a choice of RPL-1.5 or a commercial licence
adequateLICENSE.md grants a choice of RPL-1.5 or a commercial licence: open source; offering it over a network counts as distributing it, so a hosted product's changes must be published; deploying it, even for internal business use, obliges publishing the source of any changes and extensions. 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.
A note that does not affect this rating: it names the project's licence, a fact for the first screen rather than a weakness.

07 · not assessable · ratings ↑Not rated: structurally not assessable from a repository. What a person adds here.
Check it on the running system
1 check against the running system follow from the findings above: what a buyer's engineer will try, how to run it first, and what to have ready. A paid survey of this repository includes them.
A paid survey of a public repository is also reviewed: a language model reads each finding against the code and withdraws only findings it judges the code contradicts, each listed with its reason. The review is a language model's reading of the findings against the code, and it can be wrong. It never adds a finding, never raises a band, and never removes a finding from a proven check or an advisory that affects the surveyed version.
What a person adds
The survey reads what the repository can show. The code cannot settle these questions, and on them this report states nothing. Each says where its answer lives: your own engineer, the company, or an assessor you choose can settle it. Questions marked measured open with something this repository shows.
Architecture & Codebase — including AI provenance
01 · full coverage- Is the architecture right for the next three years of the product?
- Were the home-grown components reasonable choices when they were made, and are they now?
Engineering Process & SDLC Maturity
02 · high coverage- Is review real or a rubber stamp? Comment depth and time to approve need the pull request history.
- Is delivery planned and measured, or heroic?
- How are incidents run, reviewed and learned from?
Organization & Key-Person Risk
03 · partial coverage- measured One contributor authored a quarter or more of the commits in this history. Is that person part of the transaction, and for how long after it?
- Who mentors whom, and would that survive a departure?
- Can the team grow, and who stands behind the top three contributors?
- Is the seniority mix sound, and will pay survive your salary bands?
- Is the pace sustainable? Commit times cannot say: git keeps no reliable local time.
- Does the team want to stay after close?
- How are decisions made and disagreements resolved?
Product & Engineering Maturity
04 · minimal coverage- measured 91 commits landed in the last year, against 34 the year before (+168%). What drove it: new people, a deadline, or code produced faster than before?
- Can this team deliver the stated roadmap on the stated timeline?
- Does leadership know about the debt, and is time budgeted to repay it?
- Is the engineering shape consistent with the commercial story?
Security & Reliability Posture
05 · partial coverage- What has actually broken, how often, and how badly?
- What did external testing find, and was it fixed?
- What is the SOC 2, ISO 27001 or GDPR status, and where is the evidence?
Observability & Operations
06 · partial coverageNot rated: only 5 of 16 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
- Are the dashboards opened, the alerts acknowledged and the pages answered?
- Are the service-level objectives actually met?
- Who carries the pager, and how often does it go off?
- What does it cost to run, and how much headroom is there?
Fit with the Acquirer
07 · none coverageNot rated: structurally not assessable from a repository.
- This is primarily a C# codebase. Does your engineering organisation already run C# in production, or would this be the first?
- The bulk of this system sits in src/. Which of your existing systems would each of those have to absorb or replace?
- Nothing in the repository says how this is deployed. Is it shipped as a library, a binary or a service, and if it runs somewhere, who owns that environment?
- What is your tolerance for the findings above remaining unaddressed for the first two quarters after close, given everything else that will compete for this team's time?
- Which of these systems duplicate yours, and which get retired?
- What will integration cost, and in what order?
- Where does the team land in your organisation, and who reports to whom?
- Are there earn-outs, retention packages or contractor IP to assign?
- Do customer contracts limit hosting, regions or vendors?
A human assessment is Borehole's own paid service, €12,000+ (total price is determined per engagement; travel billed at cost). It is not independent of this report: the same business produced both. It is a separate contract, with its own scope, terms and reliance.

A survey is a reading by a particular version of the assessor. Older readings are kept rather than replaced, because a verification mark attests to the survey it was issued for — overwriting one would make every code already in circulation read as tampered.
