Nothing significant. Questions worth asking about Organization & Key-Person Risk, Engineering Process & SDLC Maturity.
104 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 7 findings, each with evidence. One dimension cannot be assessed without an acquirer.
- 04.62 Releases are cut from another branch than the one surveyed
Borehole's proprietary scoring is calibrated across hundreds of repositories. Each finding here reads significant, but its check has not yet held up often enough in that calibration to rate significant on its own. If one holds when someone checks it, it is significant.
- 05.26 11 locked dependencies have published vulnerabilities, 18 high or critical in what ships
- Words about people are today's: bands rather than exact shares, dates or day counts, and what the history measured rather than why.
- 2 findings from checks Borehole's calibration found wrong more often than right are no longer published.

Architecture & Codebase — including AI provenance
01 · strong · ratings ↑src/Humanizer/FluentDate/On.Days.cs is 2,345 lines, 57× this codebase's median file
adequateThe median source file here is 41 lines. 12 files exceed 1,000 lines, the largest being 2,345. 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.
A note that does not affect this rating: measured against its own codebase's median, it is below the 85th percentile of 305 surveyed projects' largest files, where this check begins to count.

adequate30 of 404 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.

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 430 non-merge commits among 35 authors; across all history, less than a quarter of 2,395. In a project with 35 recent contributors and 14 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 bus factor fell from 4 to 1
adequateYear by year, newest first, the number of people who wrote half the changes was 1, 4, 1. The team narrowed to one person, which is a different risk from one that always was: the code does not say why.
A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

Security & Reliability Posture
05 · adequate · ratings ↑11 locked dependencies have published vulnerabilities, 18 high or critical in what ships
adequate worth checking first11 of 1,238 locked dependencies match 34 published advisories in OSV, 18 of them rated high or critical. A lockfile says which version is installed, not whether the flawed code is reachable from this product, so each needs a look. Most are fixed by an upgrade, and the advisory names the version.
The check that found this reads significant, but it has not yet held up often enough in Borehole's calibration to rate a finding significant on its own. Opening website/pnpm-lock.yaml settles it. If it holds when someone checks it, this finding is significant.
| website/pnpm-lock.yaml | website/pnpm-lock.yaml — brace-expansion 1.1.18: GHSA-6j4f-fj2g-mc7p (high), fixed in 1.1.19 |

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- measured The tree carries design documentation (ARCHITECTURE.md and 1 more). Does it match what the team believes today? Ask them to walk through it against the code.
- 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 288 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 369 commits landed in the last year, against 61 the year before (+505%). 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/, website/. 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.
