dandavison/delta: technical due diligence, read from its repository
What Borehole read in dandavison/delta's code and history at 5ddd7fa: 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.

Product & Engineering Maturity
strongChange keeps returning to the same few files
adequateFive files out of 405 absorb 31% of all file-level change. Concentration like this is where debt is usually being serviced rather than repaid: the same code is reopened because it is load-bearing, fragile, or both. A repository cannot tell you which — that is a conversation with the team.

Security & Reliability Posture
not assessableThe build runs third-party code it does not pin
adequate6 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.

10 locked dependencies have published vulnerabilities
adequate10 of 277 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.
