mache

Author a mache projection schema (Topology→Node→Leaf) that maps structured data or source code into a filesystem/graph. Use when creating or debugging a *-schema.json for a new data source (SQLite/JSON) or a new source language. Covers both dialects — tree-sitter S-expression selectors for code, and JSONPath selectors for data — the gotchas (@scope on inner nodes, nested $[*], _parent traversal, the .db vs JSON-walker capability split), and how to validate the result.

Add a find_smells rule to mache — a SQL query over the projected code graph that surfaces a code smell (duplication, complexity, dead code, drift). Use when adding or debugging a SmellRule in cmd/smell_rules.go or an external $MACHE_SMELL_RULES_DIR rule. Covers the SmellRule struct, the standalone-vs-_ast table capability split, severity/polarity, tags, and the adversarial-fixture test discipline.

Mount a mache FUSE filesystem inside the project directory so agents can explore structured data without per-file permission prompts.
