aklivity/zilla: technical due diligence, read from its repository
What Borehole read in aklivity/zilla's code and history at cee0600: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Architecture & Codebase — including AI provenance
strongruntime/binding-mcp-kafka/src/main/java/io/aklivity/zilla/runtime/binding/mcp/kafka/internal/stream/McpKafkaProxyFactory.java is 10,092 lines, 129× this codebase's median file
adequateThe median source file here is 78 lines. 104 files exceed 1,000 lines, the largest being 10,092. 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.
Engineering Process & SDLC Maturity
adequate18% of recent commits change more than 2,000 lines
adequate163 of 882 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.

Product & Engineering Maturity
strongNo finding.
Security & Reliability Posture
adequate37 credential-shaped strings in the tree sit in tests, examples, documentation or local development settings
adequateStrings 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. 2 other matchs set aside: expired tokens, licence tokens a vendor verifies with a public key, or placeholder text where a key would go. None grants access to anything.
| 2 cited: AWS access key, where fakes are usual |
| 3 cited: private key block, where fakes are usual |
1 Dockerfile runs the application as root
adequateNo 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.

The build runs third-party code it does not pin
adequate9 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.

Observability & Operations
adequateNo structured logging library is in use
adequateNothing 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.
| searched 8,356 files for 10 structured logging libraries; 0 matched |
No error reporter is wired in
adequateNothing 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.
| no error reporter initialised |
