Nothing significant. Questions worth asking about Architecture & Codebase — including AI provenance, Engineering Process & SDLC Maturity.
102 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.
- 02.3 Tests are absent or token
- 2 findings from checks Borehole's calibration found wrong more often than right are no longer published.

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.
App/Functions/Editor/ViewerControl.cs is 1,349 lines, 18× this codebase's median file
adequateThe median source file here is 73 lines. 4 files exceed 1,000 lines, the largest being 1,349. 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 382 surveyed projects' largest files, where this check begins to count.

Engineering Process & SDLC Maturity
02 · adequate · ratings ↑Little of the recent change carries a trace of review
adequateIn the last 24 months, 4 of 122 commits (3.3%) carry any trace of review: a merge, a pull-request reference, a Reviewed-by or Reviewed-on trailer, a Closes/Fixes reference, a maintainer's sign-off on someone else's change, or a change applied by someone other than its author. That is low but not absent. Review may happen in a workflow this history does not record; a buyer should ask how change is approved before it ships.

Tests are absent or token
adequate worth checking first0 test files against 325 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.
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. If it holds when someone checks it, this finding is significant.

Organization & Key-Person Risk
03 · not assessable · ratings ↑Not rated: this repository belongs to a person rather than an organisation, so a finding about one contributor would be about someone the address names; the public report does not carry those, and does not rate this dimension without them. What a person adds here.
Product & Engineering Maturity
04 · not assessable · ratings ↑Not rated: only 9 of 19 checks could reach a conclusion here; the rest do not apply to this repository or could not read it. The findings below are what it could still read.
Effort is shifting from building to rewriting
adequateDeleted lines per line added rose from 0.05 to 1.03 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.

Security & Reliability Posture
05 · strong · ratings ↑2 advisories against this project in the last 24 months, 1 high or critical
adequateThe newest was published on 2025-11-17. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 2 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 1.1.1. Answer lives in: the release you run, set against each fixed version.
A note that does not affect this rating: it describes the project's advisory record, and no advisory in it is known to affect the surveyed commit.

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 No architecture or design document is in the tree, across 610 product files. Where does the design live, and who holds it?
- 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 coverageNot rated: this repository belongs to a person rather than an organisation, so a finding about one contributor would be about someone the address names; the public report does not carry those, and does not rate this dimension without them.
- Which of the people who wrote this are 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 coverageNot rated: only 9 of 19 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
- 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 App/. 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.
