Nothing significant. Questions worth asking about Organization & Key-Person Risk.

103 checks ran across 6 assessable dimensions. None found a significant problem; 1 raised something worth a question. 3 findings, each with evidence. One dimension cannot be assessed without an acquirer.

Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.
  • 3 findings from checks Borehole's calibration found wrong more often than right are no longer published.

Bus factor 1: recent work is concentrated in one contributor

adequate

In the last 24 months, one contributor authored more than half of 70 non-merge commits among 20 authors; across all history, a quarter or more of 3,242. In a project with 20 recent contributors and 17 years of history, that is a question about one person's role rather than a fragile team — but it is the question to ask.

Evidence
git shortlog -sn last 24 months: top author more than half of 70 commits; bus factor 1; 20 authors
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.

03.5

The contributor who wrote a quarter or more of this has not committed here for more than three years

adequate

One person authored a quarter or more of 3,242 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.

16 locked dependencies have published vulnerabilities, 14 high or critical

adequate

16 of 97 locked dependencies match 54 published advisories in OSV, 14 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. This lockfile pins development tools alongside what ships and does not say which is which, so some of these may never reach a user.

A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

Evidence
Gemfile.lock Gemfile.lock — activestorage 8.1.3: GHSA-xr9x-r78c-5hrm (critical), fixed in 8.1.3.1
Gemfile.lock Gemfile.lock — rack-session 2.1.1: GHSA-33qg-7wpp-89cq (critical), fixed in 2.1.2
Gemfile.lock Gemfile.lock — concurrent-ruby 1.3.6: GHSA-h8w8-99g7-qmvj (high), fixed in 1.3.7

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. See the tiers.

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.

Not rated: structurally not assessable from a repository.

  1. This is primarily a Ruby codebase. Does your engineering organisation already run Ruby in production, or would this be the first? 07.1
  2. The bulk of this system sits in lib/, gemfiles/, app/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. 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? 07.2
  4. 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?
  5. Which of these systems duplicate yours, and which get retired? Answer lives in: Your architecture07.11
  6. What will integration cost, and in what order? Answer lives in: The engagement07.12
  7. Where does the team land in your organisation, and who reports to whom? Answer lives in: Your org design07.13
  8. Are there earn-outs, retention packages or contractor IP to assign? Answer lives in: Deal terms07.14
  9. Do customer contracts limit hosting, regions or vendors? Answer lives in: Customer contracts07.15

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.

Tied to this commit and this date, and it fades after 90 days — an honest badge is one that expires. A repository with significant findings gets a neutral "read" badge rather than a red one: the library is where the range is visible, not someone else's README.

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.

This scan ran on ordinary cloud infrastructure (cloud-run), not in a hardware-isolated confidential VM. Nothing about it is attested by Google.

What an attested survey proves, and what it does not.

What this scan did with the repository — 3 steps
