Nothing significant. Questions worth asking about Organization & Key-Person Risk, Architecture & Codebase — including AI provenance.
103 checks ran across 6 assessable dimensions. None found a significant problem; 4 raised something worth a question. 6 findings, each with evidence. One dimension cannot be assessed without an acquirer.
- 8 submodule(s) this survey does not read: vendor/zippy, vendor/sat, vendor/checksums .gitmodules:1
- 3 findings from checks Borehole's calibration found wrong more often than right are no longer published.

Architecture & Codebase — including AI provenance
01 · adequate · ratings ↑src/nimble.nim is 2,795 lines, 215× this codebase's median file
adequateThe median source file here is 13 lines. 7 files exceed 1,000 lines, the largest being 2,795. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down. Measured against its own codebase's median, it is larger than 92% of 382 surveyed projects' largest files.
A note that does not affect this rating: notes like it are common in well-run projects.

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.
Engineering Process & SDLC Maturity
02 · adequate · ratings ↑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.
A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

Organization & Key-Person Risk
03 · adequate · ratings ↑Bus factor 1: recent work is concentrated in one contributor
adequateIn the last 24 months, one contributor authored three-quarters or more of 392 non-merge commits among 28 authors; across all history, a quarter or more of 1,447. In a project with 28 recent contributors and 16 years of history, that is a question about one person's role rather than a fragile team — but it is the question to ask.

The contributor who wrote a quarter or more of this has not committed here for more than three years
adequateOne person authored a quarter or more of 1,447 commits and has not committed here for more than three years, 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.

04 · adequate · ratings ↑Change keeps returning to the same few files
adequateFive files out of 870 absorb 27% 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.

The build runs third-party code it does not pin
adequate4 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.

Check it on the running system
2 checks 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- measured The repository pulls code in through git submodules (.gitmodules). A buyer receives pointers, not that code. Can every submodule be fetched without the team's credentials, and who owns each one?
- 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 140 people have committed here. Which of them are you acquiring, and which are you replacing?
- 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 252 commits landed in the last year, against 140 the year before (+80%). 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 coverageNot rated: only 16 of 34 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
- 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 4 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 Nim codebase. Does your engineering organisation already run Nim in production, or would this be the first?
- The bulk of this system sits in src/, pubgrub/, nimble-guide/. 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.
Embed the badge

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.
