  • 37% 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

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.

packages/features/watchlist/lib/freeEmailDomainCheck/freeEmailDomains.ts is 4,769 lines, 128× this codebase's median file

adequate

The median source file here is 37 lines. 26 files exceed 1,000 lines, the largest being 4,769. 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/platform/examples/base/playwright.config.ts); 1 test is individually marked to retry. 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.

117 direct dependencies in a single manifest

adequate

apps/web/package.json declares 117 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.

Fixes are 70% of recent work, up from 46%

adequate

In the last two quarters 70% of commits were fixes, against 46% in the quarters before. Rising fix work usually means quality debt is coming due, and it takes time that new work would have had.

Node.js 20 is past end of life

adequate

The code is pinned to Node.js 20 (end of life 2026-04-30). None of these receives security fixes any more; the first stopped on 2026-04-30. Moving off an unsupported runtime is rarely a one-line change, so a buyer should ask whether the upgrade is planned and what it touches.

1 credential-shaped string 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 JWT, where fakes are usual

2 Dockerfiles run 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

05.27

The build runs third-party code it does not pin

adequate

11 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; 1 step pipes 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.

75 locked dependencies have published vulnerabilities, 86 high or critical

adequate

75 of 3,815 locked dependencies match 168 published advisories in OSV, 86 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.

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

13 places insert HTML from a variable without sanitising it

adequate

13 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.

Relicensed: MIT → AGPL-3.0 (2021-09-20) → MIT (2026-04-15)

adequate

The root licence changed 2 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.

4 advisories against this project in the last 24 months, 4 high or critical

adequate

The newest was published on 2026-01-13. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 1 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 6.2.0. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: its keyword search for 'cal com' is too broad to read whole (8,357 records).

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.

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.

BOREHOLE READING NOT A CERTIFICATION MRPA-Q2Q5-MP55 2026-10-04 · 54343AA BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter MRPA-Q2Q5-MP55 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/calcom/cal.com/54343aa.svg "Borehole free reading: not for reliance. See the full report.")](https://borehole.dev/verify/MRPAQ2Q5MP55?via=badge)

Borehole reading MRPA-Q2Q5-MP55, not a certification

This commit has been surveyed 17 times

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.

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 — 3 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).
