maplibre/maplibre-compose: technical due diligence, read from its repository
What Borehole read in maplibre/maplibre-compose's code and history at e29304e: 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
stronglib/maplibre-compose/src/commonMain/kotlin/org/maplibre/compose/map/MapRuntime.kt is 1,516 lines, 21× this codebase's median file
adequateThe median source file here is 71 lines. 3 files exceed 1,000 lines, the largest being 1,516. 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
adequate5% of recent commits change more than 2,000 lines
adequate52 of 1001 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
strong26 locked dependencies have published vulnerabilities, 43 high or critical
adequate26 of 1,230 locked dependencies match 68 published advisories in OSV, 43 of them rated high or critical. 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. None of the high or critical ones is in what the product ships: they are development dependencies. This lockfile pins development tools alongside what ships and does not say which is which, so some of these may never reach a user.
