Nothing significant. Questions worth asking about Security & Reliability Posture, Observability & Operations. People was not rated.

102 checks ran across 6 assessable dimensions. None found a significant problem; 2 raised something worth a question. 10 findings, each with evidence. One dimension cannot be assessed without an acquirer. Last commit 26 October 2026.

What the repository says about itself
An earlier reading. This is the survey of 2026-11-03 by borehole 0.7.15, which is what its verification code attests to. A newer reading of the same commit exists: read the newest.
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.
  • 2 findings about one contributor are withheld: one author wrote nearly all of this repository's commits; a buyer of this report reads them.

01.6

packages/lab/src/mercury/app/widget.ts is 2,135 lines, 11× this codebase's median file

adequate

The median source file here is 188 lines. 1 file exceed 1,880 lines, the largest being 2,135. 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.

Respond to this finding

Your response is published beside the finding, not instead of it. A finding you can argue with is the point — and a wrong one is calibration data we want.

An owner's response is removed only when it is unlawful, impersonates someone, publishes personal data or a credential, or is not about the finding. Disagreeing with the report is never a reason. To report a response, or to reach us about one, write to takedown@borehole.dev.

01.15

34 errors caught and discarded in product code

adequate

34 places catch an error and do nothing with it, across 10 files (0.7 per thousand lines). Each is a failure the system will not report. They surface later as problems nobody can explain, and they are cheap to fix now.

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

05 · adequate · ratings ↑
05.2

None of the standard security guard rails are configured

adequate

There is no disclosure policy, no automated dependency updates, no named code owners and no pre-commit configuration. None of these is load-bearing on its own. Their collective absence says that security posture here is whatever the current team happens to remember to do, which is not a posture that survives the team changing.

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

34 locked dependencies have published vulnerabilities, 75 high or critical

adequate

34 of 1,632 locked dependencies match 122 published advisories in OSV, 75 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.

Relicensed: AGPL-3.0 → Apache-2.0 (2025-11-20)

adequate

The root licence changed 1 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.

A note that does not affect this rating: a licence change is a fact for the first screen, and only a narrowing of rights within two years of the surveyed commit costs "strong".

05.65

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

adequate

The newest was published on 2026-10-26. 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: 39 records name mercury with nothing tying them to this repository (CVE-2001-0442, CVE-2004-1211, CVE-2005-4406, …).

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.

Observability & Operations

06 · adequate · ratings ↑
06.1

No telemetry or error reporting is wired in anywhere

adequate

None of 262 readable files references an instrumentation, metrics or error-reporting library. If this system is in production, nobody learns that it broke from the system itself — they learn it from a customer. That is a reliability finding before it is an observability one.

Evidence
telemetry-scan searched 262 tracked text files for 16 known instrumentation libraries; manifests for metrics, tracing and error-reporting families; locked dependencies for the packages that emit; 0 matched

06.2

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
logging-scan searched 262 files for 10 structured logging libraries; 0 matched

A note that does not affect this rating
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.

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

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

Check it on the running system

8 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.

07 · none coverage

Not rated: structurally not assessable from a repository.

  1. This is primarily a Python codebase, with TypeScript alongside (28% 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 mercury/, packages/, mercury_app/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (Dockerfile). 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 SFAM-7S73-0VR4 2026-11-03 · A092E9E BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter SFAM-7S73-0VR4 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/mljar/mercury/a092e9e.svg "Borehole free reading: not for reliance. See the full report.")](https://borehole.dev/verify/SFAM7S730VR4?via=badge)

Borehole reading SFAM-7S73-0VR4, not a certification

This commit has been surveyed 2 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 — 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).
