Hazards: +//! - `#[trusted]` → `AxiomUsage::postulate`.

Walks a project root, finds every `*.ads` (spec) and `*.adb` (body) +//! file (excluding `.git`, `target`, `obj`, `lib`, `b~`, `gnatprove`), +//! and extracts a structural index. +//! +//! Ada/SPARK is one of the estate's two standard TCB languages, and +//! `ZigProve`'s obligation model is shaped after SPARK's, so this is the +//! adapter whose vocabulary the rest of the trust pipeline is written +//! in. The interesting cases are not "is there a procedure" but "what +//! did the contract say, and was any of it *assumed* rather than +//! proved". +//! +//! What we recognise: +//! - `package P is`, `package body P is` (dotted names included) — the +//! module and its unit name. +//! - `with A.B;` / `use A.B;` / `limited with A.B;` / `private with` +//! — imports. +//! - `procedure N (...)`, `function N (...)`, `overriding` forms, +//! `generic` subprograms, and nested declarations. +//! - `type T is ...`, `subtype S is ...`, `task T`, `protected T`. +//! - Contract aspects: `Pre`, `Post`, `Contract_Cases`, +//! `Loop_Invariant`, `Loop_Variant`, `Global`, `Depends`, +//! `SPARK_Mode`, `Ghost`, `Always_Terminates`, `Subprogram_Variant`. +//! - GNATprove / sparklib lemma convention: a `Ghost` procedure named +//! `Lemma_*` (or `Lemma_*` with a `Post` of `True`), which is how +//! `sparklib` encodes reusable lemmas. Recorded as +//! `sparklib:lemma` in `AxiomUsage::other` so the training pipeline +//! can tell a reusable lemma from an executable subprogram. +//! +//! Hazards (GNATprove's escape hatches — flagged for human review): +//! - `pragma Assume` and the old `--# assume` comment form. Both are +//! mapped to `AxiomUsage::postulate`: GNATprove accepts the predicate +//! without proof, which is exactly the semantics of a postulate. +//! - `pragma Annotate (GNATprove, ...)` with `Skip_Proof` / +//! `Proved => False` / `Check => Disable` — proof obligations switched +//! off in source. +//! - `pragma Suppress (...)` — runtime checks removed. +//! - `Unchecked_Conversion` / `Unchecked_Deallocation` — the type system +//! is bypassed at the boundary. +//! - `pragma Import` / `pragma Interface` — the body is trusted, not +//! proved (`spark:trusted_import`). This is the estate's Zig FFI edge, +//! so it is tagged rather than banned. +//! - `SPARK_Mode => Off` — the unit is outside the proved subset. +//! +//! ## Heuristics (not a parser) +//! +//! Ada is indentation-insensitive and `end` is heavily overloaded, so +//! subprogram bodies are delimited by the first `end ;` after the +//! body's `is`, and a declaration terminates at the first depth-0 `;` +//! (spec only) or `is` (spec + body). Comments are blanked before +//! structural scanning — but the *original* text is what lands in +//! `statement` / `proof`, so `--#` annotations stay visible to hazard +//! detection and to the discipline detector. + +#![allow(dead_code)] + +use std::collections::HashSet; +use std::path::{Path, PathBuf}; + +use anyhow::{Context, Result}; + +use super::{AxiomUsage, Corpus, CorpusEntry, DeclKind, ModuleEntry}; + +/// Walk `root` and produce a corpus from every Ada/SPARK unit. +/// +/// Pairs specifications with bodies, records textual dependencies and hazards, +/// and builds lookup and discipline indices.
