Reads strong: 3 of 5 rated dimensions are strong, 2 are adequate and none is significant.
101 checks ran across 6 assessable dimensions. Observability & Operations and Security & Reliability Posture are adequate. 7 findings, each with evidence. One dimension cannot be assessed without an acquirer.
- states a policy on AI-generated contributions .github/pull_request_template.md:3
- names Open Home Foundation .github/pull_request_template.md:5
- Words about people are today's: bands rather than exact shares, dates or day counts, and what the history measured rather than why.
- 3 findings from checks Borehole's calibration found wrong more often than right are no longer published.
- 2 findings about one contributor are withheld: one author wrote nearly all of this repository's commits; a buyer of this report reads them.

- 16% 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
- the declared share is neither decisive nor negligible, so the true figure is more sensitive to undeclared work
Architecture & Codebase — including AI provenance
01 · strong · ratings ↑Sources/Shared/Resources/Swiftgen/Strings.swift is 10,519 lines, 134× this codebase's median file
adequateThe median source file here is 78 lines. 10 files exceed 1,000 lines, the largest being 10,519. 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.

Organization & Key-Person Risk
03 · not assessable · ratings ↑Not rated: one author wrote nearly all of this repository's commits, so a finding about one contributor would be about someone its history all but names; the public report does not carry those, and does not rate this dimension without them. What a person adds here.
Product & Engineering Maturity
04 · strong · ratings ↑Ruby 3.1 is past end of life
adequateThe code is pinned to Ruby 3.1 (end of life 2025-03-26). None of these receives security fixes any more; the first stopped on 2025-03-26. Moving off an unsupported runtime is rarely a one-line change, so a buyer should ask whether the upgrade is planned and what it touches.
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 ↑The app allows plain HTTP to any server
adequateThe app's manifest allows unencrypted HTTP app-wide (NSAllowsArbitraryLoads, or cleartext traffic permitted), rather than for named domains. Anything sent over plain HTTP can be read on the network, and enterprise security reviews ask about it. Some apps need it by nature (a podcast or feed reader fetches whatever URL a feed gives), so ask which case this is.
| Sources/App/Resources/Info.plist | Sources/App/Resources/Info.plist:87 — cleartext allowed app-wide |

3 locked dependencies have published vulnerabilities, 2 high or critical
adequate3 of 110 locked dependencies match 3 published advisories in OSV, 2 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.

Observability & Operations
06 · adequate · ratings ↑No telemetry or error reporting is wired in anywhere
adequateNone of 2,928 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.
| telemetry-scan | searched 2,928 tracked text files for 16 known instrumentation libraries; manifests for metrics, tracing and error-reporting families; locked dependencies for the packages that emit; 0 matched |

One request cannot be followed through the logs

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
7 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 2,886 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 coverageNot rated: one author wrote nearly all of this repository's commits, so a finding about one contributor would be about someone its history all but 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?
- Is that code finished, or abandoned, and who still knows how it works?
- 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 1,155 commits landed in the last year, against 350 the year before (+230%). 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 05.5 found credential-shaped strings in this repository. Was each one revoked at the provider? Deleting it from the code revokes nothing; only the provider's audit log shows that it was.
- 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 Swift codebase. Does your engineering organisation already run Swift in production, or would this be the first?
- The bulk of this system sits in Sources/, HomeAssistant.xcodeproj/, fastlane/. Which of your existing systems would each of those have to absorb or replace?
- The repository carries deployment configuration (Sources/PushServer/Dockerfile and 3 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.
