Nothing significant. Questions worth asking about Security & Reliability Posture, Observability & Operations.

105 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 12 findings, each with evidence. One dimension cannot be assessed without an acquirer.

Worth checking first

Borehole's proprietary scoring is calibrated across hundreds of repositories. Each finding here reads significant, but its check has not yet held up often enough in that calibration to rate significant on its own. If one holds when someone checks it, it is significant.

9 of 24 notebooks are committed with their outputs

adequate

38% of the notebooks carry cell outputs in git, and nothing strips them before commit. Outputs bloat the history, make changes unreadable in review, and carry whatever the cells printed: data, and sometimes keys.

daft/dataframe/dataframe.py is 6,691 lines, 61× this codebase's median file

adequate

The median source file here is 109 lines. 38 files exceed 1,090 lines, the largest being 6,691. 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.

05.1

3 credential-shaped strings in the tree sit in tests, examples, documentation or local development settings

adequate

Strings shaped like credentials appear only where fakes are usual: test fixtures, examples, documentation, placeholders and local stacks. They are almost always fakes. Ask someone to confirm that none of them works anywhere, because a real key in a development file is still a real key.

Evidence
AWS access key 3 cited: AWS access key, where fakes are usual

05.6

1 Dockerfile runs the application as root

adequate

No 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.

Evidence

05.26

36 locked dependencies have published vulnerabilities, 8 high or critical in what ships

adequate worth checking first

36 of 1,490 locked dependencies match 121 published advisories in OSV, 65 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.

The check that found this reads significant, but it has not yet held up often enough in Borehole's calibration to rate a finding significant on its own. Opening src/daft-dashboard/frontend/package-lock.json and the 1 other file it cites settles it. If it holds when someone checks it, this finding is significant.

Evidence
src/daft-dashboard/frontend/package-lock.json src/daft-dashboard/frontend/package-lock.json — next 16.2.12: GHSA-2464-fhr4-w9xw (critical), fixed in 16.4.1

05.27

The build runs third-party code it does not pin

adequate

17 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.

05.21

2 shell commands built from strings

adequate

2 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.

3 deserialisers that can run code

3 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.

One request cannot be followed through the logs

06.9

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.

06.33

1 of 2 deployments run a single replica

adequate

1 deployments set `replicas: 1`, and nothing (an autoscaler, a disruption budget) adds more. Every deploy and every node drain is downtime, and the availability the buyer inherits has a ceiling.

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. 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.

  2. The bulk of this system sits in src/, daft/, tutorials/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (k8s/charts/quickstart/Chart.yaml and 11 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?

  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 NZXD-EEJ5-XVVR 2026-10-23 · 06C1FA2 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter NZXD-EEJ5-XVVR 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.

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).
