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.

apps/server/src/routes/agent/index.ts is 4,017 lines, 60× this codebase's median file

adequate

The median source file here is 66 lines. 13 files exceed 1,000 lines, the largest being 4,017. 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.

Tests are retried until they pass

adequate

The suite is configured to retry failing tests (packages/testing/playwright.config.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.

The contributor who wrote a quarter or more of this has not committed here for more than a year

adequate

One person authored a quarter or more of 2,626 commits and has not committed here for more than a year, while the repository has kept moving. The concentration figure alone would not show this. Whoever is changing this code now is not the person who wrote most of it, which is the situation an acquirer is usually told they are avoiding. The history shows only that no commits of theirs landed here, not why.

107 direct dependencies in a single manifest

adequate

apps/mail/package.json declares 107 direct dependencies. Each one is a maintenance obligation, a supply-chain surface and a potential licence question that transfers with the asset. The count says nothing about whether any given dependency was a good choice; it says how many such choices a buyer inherits.

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.

71 locked dependencies have published vulnerabilities, 44 high or critical in what ships

adequate worth checking first

71 of 2,178 locked dependencies match 163 published advisories in OSV, 88 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.

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 pnpm-lock.yaml settles it. If it holds when someone checks it, this finding is significant.

Evidence
pnpm-lock.yaml pnpm-lock.yaml — happy-dom 12.10.3: GHSA-37j7-fg3j-429f (critical), fixed in 20.0.0; a development dependency

Notes that do not affect this rating
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. 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.

05.20

2 SQL statements built from strings

adequate

2 places in product code build SQL by formatting or joining strings rather than passing parameters. In each, what the code shows going in is a table or column name, a constant, or something the line does not show, not a request's value. Ask whether any value reaches these strings, rather than a parameter.

4 places insert HTML from a variable without sanitising it

adequate

4 places set HTML from a value that is neither a literal nor passed through a sanitiser. Where the value can come from a user, that is stored cross-site scripting, and it is the first thing a buyer's security review looks for in a frontend.

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

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.

BOREHOLE READING NOT A CERTIFICATION JCBN-MGKR-V6J9 2026-11-03 · 3613273 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter JCBN-MGKR-V6J9 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).
