Moved PRELUDE_AIL const + parse_prelude fn to ailang-surface; re-exported from surface's lib.rs. surface::load_workspace rewritten 3-line shim-call → 7-line composition: load_modules_with → reserved-name check → inject parse_prelude → build_workspace(&["prelude"]). Five deletions in core: PRELUDE_JSON, load_prelude, load_workspace_with (the pd.1 shim), the top-level cfg(test) load_one fn, and the cfg(test) crate::load_module import. Production literal-"prelude" count in crates/ailang-core/src/ is now zero. Cross-form-identity preflight PASSED at module_hash 3abe0d3fa3c11c99 — parse(prelude.ail) ≡ deserialize(prelude.ail.json), so pd.3's deletion of the JSON is safe. Three new pin tests in ailang-surface/tests/: prelude_parse_pin (succeeds + min defs); prelude_module_hash_pin (cross-form-identity + literal-hex anchor); prelude_injection_pin (inject + reservation). Plan deviations (recorded in journal): switched the regression-pin fixture from non-existent examples/hello.ail.json to hello.ail; relocated 10 in-mod core tests to crates/ailang-core/tests/workspace_pin.rs because the dev-dep cycle (core ↔ surface) prevents in-mod aliasing in the lib-test target (form-a.1 T5 precedent); preserved load_one production-symbol-deletion by adding a test-mod-private load_one helper in core's mod tests for the 2 pd.1-introduced tests still consuming it. cargo test --workspace 573 green (+9 net from pd.1 baseline). bench/cross_lang.py + bench/compile_check.py exit 0; bench/check.py exit 1 with established noise envelope (bench_list_sum.bump_s, 13th consecutive observation; pd.2 is workspace-loader-only, no codegen touch — baseline pristine).

//! pd.2 (`prelude-decouple` milestone): pin the canonical identity of
|
|
//! the parsed prelude.
|
|
//!
|
|
//! Two tests:
|
|
//! 1. `prelude_ail_and_json_parse_to_identical_module` — cross-form-
|
|
//! identity preflight. Asserts that parsing `examples/prelude.ail`
|
|
//! via `ailang_surface::parse` produces a `Module` with the same
|
|
//! `module_hash` as deserialising `examples/prelude.ail.json` via
|
|
//! `serde_json::from_str`. This is the load-bearing assumption
|
|
//! that justifies pd.3's deletion of the JSON file. pd.3 drops
|
|
//! this test along with the JSON.
|
|
//! 2. `prelude_parse_yields_canonical_hash` — long-term anchor.
|
|
//! Asserts the literal hex hash of the parsed Module. Updates
|
|
//! intentionally on prelude-content changes (with a JOURNAL entry
|
|
//! naming why); accidental drift trips immediately.
