Bun (package manager) vs mise

   Bun install is scriptable and non-interactive by default (no prompts documented), supports --frozen-lockfile for reproducible CI installs, and errors out when a required dependency isn't cached (bun-docs-5, bun-docs-20, bun-docs-35). However, docs never explicitly discuss exit-code semantics or structured error output for agent consumption, and community reports note install crashes/bugs under certain conditions (bun-comm-7), suggesting real-world reliability caveats. missing for 10: explicit exit-code documentation, structured/parseable error output, independent verification that failures are cleanly reported rather than crashing.

However, none of the evidence explicitly documents exit-code semantics or structured error reporting, and the interactive 'trust' prompt for project configs (mise-docs-23) is a friction point for a fully non-interactive agent flow unless bypassed by config not shown here. missing for 10: explicit exit-code/error-format documentation, confirmation that trust prompts can be disabled non-interactively, and independent evidence of reliable failure signaling.

   The evidence confirms mise's source code is publicly hosted and readable on GitHub (jdx/mise), which the docs and community reference directly for real usage examples. However, none of the evidence explicitly names or cites an open-source license (e.g., MIT/Apache) file or statement, so the 'open license' claim isn't directly verified in this pack. Missing for 10: explicit license file/text citation, license badge or docs statement confirming license type, independent legal/third-party confirmation of licensing terms.

   Bun's docs and marketing page publish concrete speed claims (25x/30x faster) and even a specific measured number comparison (bun v1.4 0.21s vs npm v12.0.2 4.45s), which goes beyond a bare marketing slogan. However, these are all first-party vendor numbers with no disclosed benchmark methodology (hardware, package set, versions) and no independent third-party benchmark reproduction in the evidence; community comments only vaguely corroborate perceived speedups (e.g., isolated installs 10-20x faster on Windows) without rigorous numbers.
