- 19% 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 ↑homeassistant/components/mqtt/config_flow.py is 5,429 lines, 57× this codebase's median file
adequateThe median source file here is 95 lines. 117 files exceed 1,000 lines, the largest being 5,429. 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.

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.

adequateThe newest pre-release, 2026.11.0b4, is not on the branch this survey read; the newest release on it is 2026.10.4. The shipped product may differ from what this report describes. Survey the release branch too. This was read from the most recent 50,000 commits (21 Feb 2024 to 3 Nov 2026) only; older history was not read.

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
adequate4 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; 1 step pipes 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.

17 advisories against this project in the last 24 months, 11 high or critical
adequateThe newest was published on 2026-10-29. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 3 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 2026.10.4. Answer lives in: the release you run, set against each fixed version.
A note that does not affect this rating: it describes the project's advisory record, and no advisory in it is known to affect the surveyed commit.

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
2 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 15,562 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: only 4 of 10 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
- measured 2,437 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- 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 coverageNot rated: only 4 of 16 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
- 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 homeassistant/, packages/, mypy_plugins/. Which of your existing systems would each of those have to absorb or replace?
- The repository carries deployment configuration (Dockerfile and 1 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
Tied to this commit and this date, and it fades after 90 days — an honest badge is one that expires. A repository with significant findings gets a neutral "read" badge rather than a red one: the library is where the range is visible, not someone else's README.
