Nothing significant. Questions worth asking about Security & Reliability Posture, Organization & Key-Person Risk.
103 checks ran across 6 assessable dimensions. None found a significant problem; 4 raised something worth a question. 9 findings, each with evidence. One dimension cannot be assessed without an acquirer.
- 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 ↑locust/runners.py is 1,536 lines, 32× this codebase's median file
adequateThe median source file here is 48 lines. 2 files exceed 1,000 lines, the largest being 1,536. 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.

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 more than half of 921 non-merge commits among 81 authors; across all history, a quarter or more of 5,215. In a project with 81 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.

One person alone changes authentication
adequateIn the last 24 months, of 81 contributors, a single person made every change to: authentication (10 commits). These are the parts where a mistake is expensive and where knowledge is hardest to rebuild. Ask who else could change them safely tomorrow.

Security & Reliability Posture
05 · adequate · ratings ↑The build runs third-party code it does not pin
adequate7 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.

2 shell commands built from strings

16 locked dependencies have published vulnerabilities, 21 high or critical
adequate16 of 1,023 locked dependencies match 44 published advisories in OSV, 21 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.

Observability & Operations
06 · adequate · ratings ↑No structured logging library is in use
adequateNothing references a structured logging library. Logs that are written to be read by a person are not searchable by a machine, which means incident response here is proportional to how well someone remembers the codebase rather than to what the tooling can find.

No error reporter is wired in
adequateNothing in the service initialises an error reporter (Sentry, Rollbar, Bugsnag, Honeybadger or an APM agent). An exception in production reaches a person only if someone is reading the logs, which usually means a customer reports it first.

Fit with the Acquirer
07 · not assessable · ratings ↑Not rated: structurally not assessable from a repository. What a person adds here.
Check it on the running system
5 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 No architecture or design document is in the tree, across 205 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 coverage- measured 396 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- 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- measured No threat model is in the tree of what looks like a running service. Does one exist elsewhere, and who owns 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 coverage- measured Nothing in the tree backs up or restores data. How is data backed up, and has a restore ever been rehearsed?
- measured No alert rule is defined in the repository. Where are alerts defined, who receives them, and when did one last fire?
- 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 TypeScript codebase, with Python alongside (33% of source files). Does your engineering organisation already run TypeScript in production, or would this be the first?
- The bulk of this system sits in locust/, pytest_locust/. Which of your existing systems would each of those have to absorb or replace?
- The repository carries deployment configuration (Dockerfile and 2 more). Does that match your deployment and on-call model, or does it need rehosting first?
- 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.
