Reads strong. BUSL-1.1 since 2022-09-07: source available, not open source; production use restricted until the change date.

100 checks ran across 6 assessable dimensions. 5 of 6 rated dimensions are strong, 1 is adequate and none is significant. Organization & Key-Person Risk is adequate. 9 findings, each with evidence. One dimension cannot be assessed without an acquirer.

This repository reads strong. Show it in your README: the badge links to a page where anyone can check the reading. 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.

akka-distributed-data/src/main/java/akka/cluster/ddata/protobuf/msg/ReplicatorMessages.java is 23,995 lines, 228× this codebase's median file

adequate

The median source file here is 105 lines. 45 files exceed 1,050 lines, the largest being 23,995. 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. Measured against its own codebase's median, it is larger than 93% of 382 surveyed projects' largest files.

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.

The next contributor after the top one has not committed here for more than a year

adequate

The #3 contributor of the last three years (less than a quarter of the commits) has not committed here for more than a year, while the repository is still active. These are the people a buyer assumes would step up if the top contributor stopped. The history shows only that no commits of theirs landed here, not why.

100 files still carry code deprecated more than two years ago

adequate

100 files were marked deprecated over two years ago and still are, the oldest since Jan 2011. A deprecation is a promise to remove. Ask what still depends on these, and whether removing them is scheduled.

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

The build runs third-party code it does not pin

adequate

8 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.

05.66

The licence is BUSL-1.1: source available, not open source

adequate

LICENSE grants BUSL-1.1: source available, not open source; production use restricted until the change date. The reading comes from the licence's own title and clauses. Whether the terms fit the buyer's intended use, and whether any paid licence transfers with the code, is a question for counsel and the licensor.

A note that does not affect this rating: it names the project's licence, a fact for the first screen rather than a weakness.

Relicensed: Apache-2.0 → BUSL-1.1 (2022-09-07)

adequate

The root licence changed 1 time(s). The latest terms restrict what users, hosts or a buyer may do in ways the earlier ones did not. Code taken under the old terms stays under them, so both matter in diligence.

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".

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.

1 of 1 deployments run a single replica

adequate

1 deployments set `replicas: 1`, and nothing (an autoscaler, a disruption budget) adds more. Every deploy and every node drain is downtime, and the availability the buyer inherits has a ceiling.

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

Check it on the running system

4 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 Scala codebase. Does your engineering organisation already run Scala in production, or would this be the first? 07.1
  2. The bulk of this system sits in akka-docs/, akka-actor/, akka-remote/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. Nothing in the repository says how this is deployed. Is it shipped as a library, a binary or a service, and if it runs somewhere, who owns that environment? 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 DXQF-7HBZ-6REG, not a certification

This commit has been surveyed 6 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).
