Nothing significant. Questions worth asking about Organization & Key-Person Risk, Engineering Process & SDLC Maturity.
104 checks ran across 6 assessable dimensions. None found a significant problem; 2 raised something worth a question. 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:34
- Words about people are today's: bands rather than exact shares, dates or day counts, and what the history measured rather than why.
- 2 findings from checks Borehole's calibration found wrong more often than right are no longer published.

Architecture & Codebase — including AI provenance
01 · strong · ratings ↑rich/_emoji_codes.py is 3,611 lines, 38× this codebase's median file
adequateThe median source file here is 94 lines. 6 files exceed 1,000 lines, the largest being 3,611. 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.

Engineering Process & SDLC Maturity
02 · adequate · ratings ↑26% of commit subjects say nothing about the change
adequate887 of 3,387 subjects are either under twelve characters or one of the standard placeholders — wip, fix, update. The history is therefore not usable for reconstructing why a decision was taken, which is the main thing an inheriting engineer needs it for. It says nothing about code quality and a great deal about how much context transfers with the asset.

Organization & Key-Person Risk
03 · adequate · ratings ↑Bus factor 1: recent work is concentrated in one contributor
adequateIn the last 24 months, one contributor authored three-quarters or more of 345 non-merge commits among 33 authors; across all history, more than half of 3,271. In a project with 33 recent contributors and 7 years of history, that is a question about one person's role rather than a fragile team — but it is the question to ask.

The bus factor fell from 5 to 1
adequateYear by year, newest first, the number of people who wrote half the changes was 1, 1, 5, 2. The team narrowed to one person, which is a different risk from one that always was: the code does not say why.

Security & Reliability Posture
05 · strong · ratings ↑The build runs third-party code it does not pin
adequate3 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. 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.
A note that does not affect this rating: notes like it are common in well-run projects.

6 locked dependencies have published vulnerabilities, 3 high or critical
adequate6 of 49 locked dependencies match 13 published advisories in OSV, 3 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.
A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.
| poetry.lock | poetry.lock — virtualenv 20.34.0: GHSA-94p9-xgh2-xp45 (high), fixed in 21.7.12; a development dependency |

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- 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 more than half of the commits in this history. Is that person part of the transaction, and for how long after it?
- measured imgs/ (less than a quarter of the files) has not changed in 18 months while the rest of the repository moved. 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- 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 5 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 rich/, assets/, questions/. Which of your existing systems would each of those have to absorb or replace?
- Nothing in the repository says how this is deployed. Is it shipped as a library, a binary or a service, and if it runs somewhere, 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?
- 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.

4 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.
