Reads strong: 5 of 6 rated dimensions are strong, 1 is adequate and none is significant.

104 checks ran across 6 assessable dimensions. Security & Reliability Posture is adequate. 9 findings, each with evidence. One dimension cannot be assessed without an acquirer.

This repository reads strong. Show it in your README: the badge links to a page where anyone can check the reading. If you embed it: link it to the report, remove it if the report is delisted, and do not present it as a certification or an endorsement.

src/zenml/zen_stores/sql_zen_store.py is 17,109 lines, 234× this codebase's median file

adequate

The median source file here is 73 lines. 46 files exceed 1,000 lines, the largest being 17,109. 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. Measured against its own codebase's median, it is larger than 93% of 382 surveyed projects' largest files.

119 of 288 migrations cannot be rolled back

adequate

119 schema migrations (41%) have no working way back: an empty `downgrade`, a `down` that does nothing, or a data migration with no reverse. A bad deploy that includes one is recovered from a backup, not reverted. Ask when a restore was last rehearsed.

155 dependencies float, and no lockfile is committed

adequate

Dependency 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.

A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

05.27

The build runs third-party code it does not pin

adequate

4 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; 7 steps pipe 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.

05.21

4 shell commands built from strings

adequate

4 places run a command through a shell (`shell=True`, `os.system`, `exec` with a template) rather than passing arguments. Where any part comes from outside, it is command injection. Ask where each one's input comes from.

1 deserialiser that can run code

adequate

1 places read data with a deserialiser that executes what it reads (pickle). That is safe on data the system wrote itself and remote code execution on anything else. Ask where each one's input comes from.

1 of 2 Kubernetes workloads declare no resource limits

adequate

1 workload manifests set no CPU or memory limits. One pod that leaks memory or spins can starve everything else on its node, and the scheduler cannot plan capacity for what it cannot see.

6 advisories against this project in the last 24 months, 2 high or critical

adequate

The newest was published on 2026-08-07. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. None of them affects the surveyed version. The record is incomplete: NVD: 2 records name zenml with nothing tying them to this repository (CVE-2024-28424, CVE-2024-4680).

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.

No error reporter is wired in

adequate

Nothing 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.

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. See the tiers.

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.

Fit with the Acquirer

07 · none coverage

Not rated: structurally not assessable from a repository.

  1. This is primarily a Python codebase. Does your engineering organisation already run Python in production, or would this be the first? 07.1
  2. The bulk of this system sits in src/, infra/, helm/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (docker-compose.yml and 26 more). Does that match your deployment and on-call model, or does it need rehosting first? 07.2
  4. 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?
  5. Which of these systems duplicate yours, and which get retired? Answer lives in: Your architecture07.11
  6. What will integration cost, and in what order? Answer lives in: The engagement07.12
  7. Where does the team land in your organisation, and who reports to whom? Answer lives in: Your org design07.13
  8. Are there earn-outs, retention packages or contractor IP to assign? Answer lives in: Deal terms07.14
  9. Do customer contracts limit hosting, regions or vendors? Answer lives in: Customer contracts07.15

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.

BOREHOLE READING NOT A CERTIFICATION 36HA-8G0Z-3JQ2 2026-10-22 · F3824DF BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter 36HA-8G0Z-3JQ2 at borehole.dev/verify.

The code commits to the 106 checks this run performed, the bands they produced, and the commit they were read at. It does not cover checks written since.

Put the mark in your README

The image is wrapped in a link to the verification page, so a reader can check it rather than take it on trust. If you embed it: link it to the report, remove it if the report is delisted, and do not present it as a certification or an endorsement.

[![Borehole reading, not a certification](https://borehole.dev/badge/zenml-io/zenml/f3824df.svg "Borehole free reading: not for reliance. See the full report.")](https://borehole.dev/verify/36HA8G0Z3JQ2?via=badge)

Borehole reading 36HA-8G0Z-3JQ2, not a certification

Quoted evidence

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.

Where this scan ran

This scan ran on ordinary cloud infrastructure (cloud-run), not in a hardware-isolated confidential VM. Nothing about it is attested by Google.

What an attested survey proves, and what it does not.

What this scan did with the repository — 7 steps

Written by the steps themselves as they ran, not described afterwards. A hand-written account of a data flow drifts the first time somebody changes the flow and not the account.

An automated reading of a repository's code and its history up to one commit, with public advisory records. It may be wrong, it is not legal, financial, investment or security advice, and it does not replace diligence by a qualified person. It is provided for information: nobody may rely on it (Borehole's terms, section 3).
