Nothing significant. Questions worth asking about Observability & Operations.

105 checks ran across 6 assessable dimensions. None found a significant problem; 1 raised something worth a question. 5 findings, each with evidence. One dimension cannot be assessed without an acquirer.

Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.
  • 1 finding from checks Borehole's calibration found wrong more often than right is no longer published.

  • 5% 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
  • only 40 non-merge commits to measure across
  • deep scan blamed 134 of 134 counted files
644 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.

02.6

Almost no process scaffolding exists in the repository

adequate

Of five ordinary markers — CI workflows, CODEOWNERS, a pull-request template, pre-commit hooks, contribution guidance — none are present. Branch protection itself is a GitHub setting rather than a file, so this is a reading of proxies and not of the rules themselves. What it does establish is that the process is not written down anywhere a new engineer would find it.

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

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.

Observability & Operations

06 · adequate · ratings ↑
06.1

No telemetry or error reporting is wired in anywhere

adequate

None of 131 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 131 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 131 files for 10 structured logging libraries; 0 matched

06.8

One request cannot be followed through the logs

adequate

Nothing in the service carries a request or correlation id, and there is no tracing. When a customer reports a failure, the log lines that belong to their request cannot be picked out from everyone else's.

Evidence
request ids no request id, correlation id or tracing found

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.

error reporting no error reporter initialised

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.

Fit with the Acquirer

07 · none coverage

Not rated: structurally not assessable from a repository.

  1. This is primarily a JavaScript codebase. Does your engineering organisation already run JavaScript in production, or would this be the first? 07.1
  2. The bulk of this system sits in executors/, collectors/, models/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (executors/wechat-mp-publish/deploy/Dockerfile and 1 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?
  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.

Embed the badge

Tied to this commit and this date, and it fades after 90 days — an honest badge is one that expires. A repository with significant findings gets a neutral "read" badge rather than a red one: the library is where the range is visible, not someone else's README.

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.
