|

//! Acceptance suite for T M7.9 ("Audit lint configuration"). The
|
|
//! five tests below correspond, in order, to the five bullets in
|
|
//! `spec/pmacs-tasks.tex` § "T M7.9 -- Audit lint configuration".
|
|
//!
|
|
//! Bullet 1: detects all seven rule classes
|
|
//! Bullet 2: emits JSON with file/line/rule/snippet
|
|
//! Bullet 3: sample CI workflow YAML present for three forges
|
|
//! Bullet 4: lint over the (pre-M7.11) REPL package's in-tree source
|
|
//! Bullet 5: 1000-line package lints in under one second

// The spec lists seven *rule classes*; the implementation expands them into
|
|
// fifteen tree-sitter patterns (e.g., the "no-FFI escape hatches" class
|
|
// covers four distinct patterns: ffi.cdef/load/metatype, package.loadlib,
|
|
// package.cpath mutation; consolidating them under a single rule name would
|
|
// make findings less actionable). The acceptance check confirms every
|
|
// *class* fires at least once; the per-pattern test suite in
|
|
// `src/audit/mod.rs::tests` verifies the discrimination within a class.
