Nothing significant. Questions worth asking about Organization & Key-Person Risk, Security & Reliability Posture.
35 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 10 findings, each with evidence. One dimension cannot be assessed without an acquirer.
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.
- 03.5 The contributor who wrote more than half of this has not committed here for more than three years
- Words about people are today's: bands rather than exact shares, dates or day counts, and what the history measured rather than why.
- 1 finding rated significant by a check that has not yet held up in Borehole's calibration is now worth checking first.
- 1 finding from checks Borehole's calibration found wrong more often than right is no longer published.

Architecture & Codebase — including AI provenance
01 · adequate · ratings ↑test/app.router.js is 1,218 lines, 16× this codebase's median file
adequateThe median source file here is 75 lines. 2 files exceed 1,000 lines, the largest being 1,218. 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.

Engineering Process & SDLC Maturity
02 · adequate · ratings ↑Almost no process scaffolding exists in the repository
adequateOf five ordinary markers — CI workflows, CODEOWNERS, a pull-request template, pre-commit hooks, contribution guidance — 1 is present: CI workflows. Branch protection itself is a GitHub setting rather than a file, so this is a reading of proxies and not of the rules themselves. What it does establish is that the process is not written down anywhere a new engineer would find it.

Organization & Key-Person Risk
03 · adequate · ratings ↑Bus factor 1: the history is concentrated in one contributor
adequateOne contributor authored more than half of 5,685 non-merge commits across 394 distinct authors. 1 author accounts for half of all commits. 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.

76% of contributors committed exactly once and never returned
adequate299 of 394 contributors made a single commit. That is the signature of a codebase that is hard to join: people arrive, land one change and do not come back. It matters after an acquisition because putting new engineers on this system is the first thing anyone will try to do.

The contributor who wrote more than half of this has not committed here for more than three years
adequate worth checking firstOne person authored more than half of 5,685 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.
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.

Product & Engineering Maturity
04 · adequate · ratings ↑Change keeps returning to the same few files
adequateFive files out of 1,042 absorb 26% of all file-level change. Concentration like this is where debt is usually being serviced rather than repaid: the same code is reopened because it is load-bearing, fragile, or both. A repository cannot tell you which — that is a conversation with the team.

Security & Reliability Posture
05 · adequate · ratings ↑37 dependencies float, and no lockfile is committed
adequateDependency versions are declared as ranges and no lockfile is committed, so a build today does not necessarily produce what a build last month produced. That matters twice over in a transaction: the thing being bought cannot be reproduced exactly, and a compromised upstream release arrives without anyone choosing to take it.

Licence text does not match a standard licence
adequateLICENSE exists but its text does not match any standard licence. A bespoke or hand-edited licence is not wrong, but it cannot be cleared by recognising its name: counsel has to read it, and until they do neither side knows precisely what rights transfer with the code.

Observability & Operations
06 · adequate · ratings ↑No telemetry or error reporting is wired in anywhere
adequateNone of 164 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.

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.
Engineering Process & SDLC Maturity
02 · high coverage- Incident response practice is not visible in a repository.
Organization & Key-Person Risk
03 · partial coverage- Hiring pipeline, bench depth and retention are not visible in a repository.
- Whether the dominant contributor is part of the transaction.
- Seniority, levelling and who actually mentors whom.
- Whether the team wants to stay after the deal closes.
Product & Engineering Maturity
04 · minimal coverage- Roadmap credibility requires the data room.
- Whether technical debt is acknowledged and funded.
Security & Reliability Posture
05 · partial coverage- Incident history and failure-mode analysis are not in the repository.
Observability & Operations
06 · partial coverage- Whether anyone watches the telemetry that exists.

07 · none coverageNot rated: structurally not assessable from a repository.
- This is a JavaScript codebase. Does your engineering organisation already run JavaScript in production, or would this be the first?
- One contributor authored 62% of this history. Is that person part of the transaction, and for how long after it?
- The bulk of this system sits in test/, lib/, docs/. Which of your existing systems would each of those have to absorb or replace?
- There is no deployment configuration in the repository. Where does this actually run today, and 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?
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.

5 pieces of evidence on this report quote the repository directly. Four checks quote text: up to five TODO-style comments, up to four commit subjects, up to five unpinned dependency lines and one status line from the README's first screen, such as “no longer maintained”. In each case the text is the evidence, which is why it is kept by default.
This rewrites every stored reading of this repository, and every later reading, including a re-read, is stored without the quoted text. The facts we keep to re-read it still hold the lines, as the privacy notice says. The pointers stay.
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.
