acinq/eclair: technical due diligence, read from its repository
What Borehole read in acinq/eclair's code and history at c96c3d4: 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
strongeclair-core/src/main/scala/fr/acinq/eclair/channel/fsm/Channel.scala is 4,022 lines, 23× this codebase's median file
adequateThe median source file here is 172 lines. 3 files exceed 1,720 lines, the largest being 4,022. 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.

Security & Reliability Posture
adequate1 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.

Observability & Operations
strongNo 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.
