Significant: one contributor carries the recent work.
1 of 6 assessable dimensions carries significant findings, 2 are adequate and 3 are strong. 11 findings, each with its evidence: the commit, path and lines it rests on, or, when something is missing, what was looked for. One dimension cannot be assessed without an acquirer.
- 03.1 Significant: Bus factor 1: recent work is concentrated in one contributor
- 1 finding from checks Borehole's calibration found wrong more often than right is no longer published.

- low trailer coverage: the convention may not be in consistent use
- no widespread author/committer date divergence
- the declared share is neither decisive nor negligible, so the true figure is more sensitive to undeclared work

03 · significant findings · ratings ↑Bus factor 1: recent work is concentrated in one contributor
significant findingsIn the last 24 months, one contributor authored three-quarters or more of 91 non-merge commits among 10 authors; across all history, a quarter or more of 1,179. This is the single most expensive thing to discover after closing, and the repository cannot tell you whether that person is part of the transaction.

The contributor who wrote a quarter or more of this has not committed here for more than a year
adequateOne person authored a quarter or more of 1,179 commits and has not committed here for more than a year, 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.

Product & Engineering Maturity
04 · strong · ratings ↑Effort is shifting from building to rewriting
adequateDeleted lines per line added rose from 0.50 to 2.27 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 · adequate · ratings ↑1 Dockerfile runs the application as root
adequateNo USER instruction switches away from root, so the process runs with full privileges inside the container. It is a one-line fix and an ordinary expectation, which is why its absence is worth asking about: it usually says more about whether anyone has reviewed the deployment than about this container specifically.

The build runs third-party code it does not pin
adequate2 steps pipe a download straight into a shell. 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.

5 locked dependencies have published vulnerabilities, 6 high or critical
adequate5 of 94 locked dependencies match 10 published advisories in OSV, 6 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. None of the high or critical ones is in what the product ships: they are development dependencies; they are optional extras of a package, installed only on request.

Relicensed: MIT → AGPL-3.0 (2019-03-17)
adequateThe root licence changed 1 time(s). The latest terms restrict what users, hosts or a buyer may do in ways the earlier ones did not. Code taken under the old terms stays under them, so both matter in diligence.
A note that does not affect this rating: a licence change is a fact for the first screen, and only a narrowing of rights within two years of the surveyed commit costs "strong".

Observability & Operations
06 · adequate · ratings ↑No telemetry or error reporting is wired in anywhere
adequateNone of 231 readable files references an instrumentation, metrics or error-reporting library. If this system is in production, nobody learns that it broke from the system itself — they learn it from a customer. That is a reliability finding before it is an observability one.

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.

One request cannot be followed through the logs

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
8 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- 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 One contributor authored a quarter or more of the commits in this history. Is that person part of the transaction, and for how long after it?
- measured The repository went quiet for 12 months, from July 2024 to August 2025, then 36 commits landed in the six weeks after. Where was the work of that period done, and is it in this history? The history shows the gap, not why it happened.
- 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 89 commits landed in the last year, against 2 the year before (+4350%). 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- 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 Python codebase. Does your engineering organisation already run Python in production, or would this be the first?
- The bulk of this system sits in roles/, library/, playbooks/. Which of your existing systems would each of those have to absorb or replace?
- 92% of lines added in the last 12 months (19% of added lines) came through AI-declared commits. Does your organisation have a policy on inheriting and maintaining that code, and does your engineering team's tooling match how it was produced?
- The repository carries deployment configuration (Dockerfile). 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.
