Nothing significant. Questions worth asking about Security & Reliability Posture, Observability & Operations.

104 checks ran across 6 assessable dimensions. None found a significant problem; 5 raised something worth a question. 11 findings, each with evidence. One dimension cannot be assessed without an acquirer.

zellij-server/src/tab/unit/tab_tests.rs is 17,918 lines, 81× this codebase's median file

adequate

The median source file here is 219 lines. 32 files exceed 2,190 lines, the largest being 17,918. 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 305 surveyed projects' largest files, where this check begins to count.

7% of recent commits change more than 2,000 lines

adequate

42 of 564 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.

Bus factor 1: recent work is concentrated in one contributor

adequate

In the last 24 months, one contributor authored three-quarters or more of 609 non-merge commits among 86 authors; across all history, a quarter or more of 3,151. In a project with 86 recent contributors and 6 years of history, that is a question about one person's role rather than a fragile team — but it is the question to ask.

10% of bug fixes add or change a test

Of 319 fixes in the last 24 months, 31 touched a test. A fix without the test that would have caught the bug can quietly come back, and the suite never learns from what went wrong.

Security & Reliability Posture

05 · adequate · ratings ↑
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.

Evidence
.github/workflows/e2e.yml .github/workflows/e2e.yml:35 — action pinned by tag

Notes that do not affect this rating
05.26

12 locked dependencies have published vulnerabilities

adequate

12 of 536 locked dependencies match 13 published advisories in OSV. 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.

05.9

1 vendored component with no licence

adequate

Third-party code is committed into this repository without any statement of the terms it arrived under. Unknown terms are harder to deal with than inconvenient ones: an awkward licence can be complied with, an absent one cannot. Each of these needs its origin established before the code changes hands.

Observability & Operations

06 · adequate · ratings ↑
06.1

No telemetry or error reporting is wired in anywhere

adequate

None of 500 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 500 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

06.9

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.

Evidence
error reporting no error reporter initialised

1 of 1 deployed images carry no version, or `latest`

1 images in the deployment configuration are named without a version or as `latest`. A redeploy can change the software without a commit, a rollback has nothing to roll back to, and nobody can say from the repository what is running.

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.

Not rated: structurally not assessable from a repository.

  1. This is primarily a Rust codebase. Does your engineering organisation already run Rust in production, or would this be the first? 07.1
  2. The bulk of this system sits in zellij-server/, zellij-utils/, src/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (docker-compose.yml). 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.

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.

Borehole reading YR0P-AWFR-EF17, not a certification

This commit has been surveyed 8 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).
