Conversation
This PR documents the new `lake profile` command, which builds an executable target, records a CPU profile with samply, symbolicates and demangles Lean compiler names, and serves the result for Firefox Profiler. Depends on leanprover/lean4#12545 — do not merge until that PR lands. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

This PR documents the
lake samplycommand, which builds an executable target, records a CPU profile of it with samply, symbolicates the raw addresses and demangles Lean's compiled names before writing a Firefox Profiler file.The command is added by "feat: add
lake samplycommand", leanprover/lean4#12545, which is not yet merged.lakeHelpcompares its contents against the output of the installedlake --help, so this cannot build until that lands; it stays a draft until then.🤖 Prepared with Claude Code
