- 18% of non-merge commits carry any trailer at all
- low trailer coverage: the convention may not be in consistent use
- no widespread author/committer date divergence

Architecture & Codebase — including AI provenance
01 · strong · ratings ↑scaffold/acme_root/clients/typescript/src/schema.d.ts is 4,169 lines, 52× this codebase's median file
adequateThe median source file here is 80 lines. 6 files exceed 1,000 lines, the largest being 4,169. 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.

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.
Engineering Process & SDLC Maturity
02 · adequate · ratings ↑16% of recent commits change more than 2,000 lines
adequate23 of 146 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.

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

Security & Reliability Posture
05 · strong · ratings ↑2 SQL statements built from strings
adequate2 places in product code build SQL by formatting or joining strings rather than passing parameters. 1 of them put a value into the string; in the rest, what the code shows going in is a table or column name, a constant, or something the line does not show. Ask whether any value reaches these strings, rather than a parameter.

1 locked dependency has published vulnerabilities
adequate1 of 394 locked dependencies match 1 published advisories in OSV. 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.

Observability & Operations
06 · strong · ratings ↑No finding. 16 checks ran and none fired; the rejection log below says why each did not.
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
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 The tree carries design documentation (architecture.md and 49 more). Does it match what the team believes today? Ask them to walk through it against the code.
- 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 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 Alert rules are defined in the repository. 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, with TypeScript alongside (21% of source files). Does your engineering organisation already run Python in production, or would this be the first?
- The bulk of this system sits in scaffold/, checkers/, skills/. Which of your existing systems would each of those have to absorb or replace?
- The repository carries deployment configuration (scaffold/acme_root/deployment/docker/api.Dockerfile and 107 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.
Embed the badge
