Nothing significant. Questions worth asking about Security & Reliability Posture, Architecture & Codebase — including AI provenance.

104 checks ran across 6 assessable dimensions. 2 findings are worth checking first. 11 findings, each with evidence. One dimension cannot be assessed without an acquirer.

What the repository says about itself
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.

  • 05.20 16 SQL statements built from strings
  • 05.26 11 locked dependencies have published vulnerabilities, 5 high or critical in what ships
Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.
  • 2 findings from checks Borehole's calibration found wrong more often than right are no longer published.
  • The file and line of 5 credential-shaped matches are withheld. File and line are shown to whoever GitHub says controls this repository, signed in, and to a buyer of this report.

  • 50% 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
388,734 lines excluded as lockfiles, vendored or generated.
This is a lower bound. It counts what the repository declares. Undeclared AI authorship is invisible here, and a single rebase removes the trailers this rests on. Absence of a declaration is absence of disclosure, not absence of AI authorship.

1 base image floats: no version, or `latest`

adequate

1 of 7 `FROM` lines in product Dockerfiles name an image without a version, or with `latest`. Each build pulls whatever the registry serves that day, so the image that ships can change without a commit, and last month's build cannot be reproduced. Pin a version, or a digest.

Evidence
Dockerfile Dockerfile:64 — base image without a version

headroom/proxy/handlers/openai.py is 11,767 lines, 55× this codebase's median file

adequate

The median source file here is 211 lines. 15 files exceed 2,110 lines, the largest being 11,767. 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.

Tests are retried until they pass

adequate

The suite is configured to retry failing tests (sdk/typescript/test/client.test.ts). A retry turns a flaky test green without saying why it failed, so a green build means the tests passed eventually. Ask how many retries a typical run needs, and which tests need them.

A note that does not affect this rating: notes like it are common in well-run projects.

31 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
JWT 5 cited: JWT, where fakes are usual

16 SQL statements built from strings

adequate worth checking first

16 places in product code build SQL by formatting or joining strings rather than passing parameters, and in 12 of them a value, not a table or column name, goes into the string. Where any of those values comes from a request, it is an injection point. Each site needs a look; the fix, parameters, is small.

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 headroom/cli/memory.py:107 settles it. If it holds when someone checks it, this finding is significant.

Evidence

11 locked dependencies have published vulnerabilities, 5 high or critical in what ships

adequate worth checking first

11 of 832 locked dependencies match 58 published advisories in OSV, 38 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 uv.lock and the 1 other file it cites settles it. If it holds when someone checks it, this finding is significant.

Evidence
uv.lock uv.lock — certifi 2026.1.4: GHSA-6q48-6c7w-9gw2 (critical), fixed in 2026.10.19

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; 2 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.

1 advisory against this project in the last 24 months, 1 high or critical

The newest was published on 2026-08-27. 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.

No structured logging library is in use

adequate

Nothing references a structured logging library. Logs that are written to be read by a person are not searchable by a machine, which means incident response here is proportional to how well someone remembers the codebase rather than to what the tooling can find.

Evidence

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.

Not rated: structurally not assessable from a repository. What a person adds here.

Check it on the running system

6 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.

  1. This is primarily a Python codebase, with Rust alongside (20% of source files). 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 headroom/, crates/, plugins/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (Dockerfile and 5 more). Does that match your deployment and on-call model, or does it need rehosting first? 07.2

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.

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).
