# Doc-impl alignment grep, promoted from the manual verification step
# to a permanent gate. Run from anywhere; resolves to the plugin tree itself.
#
# Verifies:
#   1. Every `outlook-*` tool name in `platform/plugins/docs/references/outlook-guide.md`
#      resolves to a `server.tool("outlook-...", ...)` registration in mcp/src/index.ts.
#   2. Every `[outlook-mcp]` log-line shape in outlook-guide.md matches a
#      log({event:"..."}) literal in mcp/src/.
#   3. Every tool name in `PLUGIN.md` frontmatter matches a registration in mcp/src/index.ts.
#   4. Public-agent isolation: `outlook` does not appear in public-agent assembly files.
#   5. Bearer-token redaction: log.ts contains the redaction regex pair.
#
# Exit non-zero on any mismatch. Print the first diverging item.
