refactor(test): hoist duplicated test helpers into ailang-test-support
closes #60 The fixture-corpus filter (NON_PARSEABLE_FIXTURES + list_ail_fixtures) was copy-pasted across three test crates and drifted out of sync as new reject fixtures landed; the examples_dir / workspace_root path walk was reimplemented ~30 more times across the suite, under two spellings (workspace_root / ws_root). Introduce crates/ailang-test-support — a zero-dependency, dev-only leaf crate — as the single home for these helpers: - NON_PARSEABLE_FIXTURES, list_ail_fixtures - workspace_root, examples_dir - canonical_workspace_root (symlink-resolved variant, for the tsan/ race tests that feed the root into native build steps) All integration-test copies across ailang-core, ailang-surface, ailang-prose, ailang-check, and ail now import from the shared crate; the local definitions and their now-orphaned path imports are removed. Path helpers resolve via the support crate's own CARGO_MANIFEST_DIR, so they return the correct absolute paths from any caller. ail_bin helpers are intentionally left in place: they depend on env!("CARGO_BIN_EXE_ail"), which Cargo only defines when compiling the ail crate's own integration tests, so they cannot move to a shared crate. Behaviour-identical: same paths, same fixture lists; full workspace test suite green. Net -177 LOC. |

feat(check): mir.1a — typed-MIR types + post-mono lower_to_mir + elaborate_workspace (additive)
First half of spec iteration mir.1 (docs/specs/0060-typed-mir.md, plan docs/plans/0114-mir.1a-mir-infrastructure.md). Purely additive: a new leaf crate plus a post-mono lowering walk plus the front-end entry. Nothing consumes MIR yet — codegen and the CLI are untouched — so the whole existing suite stays green (102 test-result-ok lines, 0 failed; the one ignored is the #49 pin, which lifts at mir.4). mir.1b flips codegen to consume MIR and deletes the synth_with_extras mirror. What lands: - `ailang-mir` (new leaf crate, depends only on ailang-core): MTerm / MArg / MArm / MLoopBinder / MNewArg / Callee / Mode / StrRep / MirDef / MirModule / MirWorkspace, structurally complete over all 17 Term variants plus the dedicated Str split (MTerm::Str{lit,rep}). Every later-iteration annotation field exists now at a mir.1 default (App.callee = Indirect, MArg.mode/consume_count = Owned/1, Str.rep = Static, New.elem = None); the struct shape will not change across mir.2–mir.5, only the values. MTerm::ty() reads the carried type. - `ailang-check::lower_to_mir`: the post-mono walk. Carries no second type engine — it calls the canonical `synth` per node with fresh throwaway inference scaffolding (subst/counter/residuals/…), applies the substitution, and threads only the lexical locals/loop_stack, maintained by the same push/pop rules synth uses (Let, Loop, Lam, LetRec, and Match via synth's own type_check_pattern). This is the "one engine, not two" property the milestone buys, on the producer side. - `ailang-check::elaborate_workspace`: the single front-end entry — check (diagnostics gate) → desugar+lift → monomorphise → lower_to_mir — transcribed from the CLI build path. check_workspace stays for the diagnostics-only callers. - Three ty-fill pins (crates/ailang-check/tests/lower_to_mir_ty.rs) load the #51/#53/#49 witnesses as fixtures and elaborate the whole workspace, so lower_to_mir is exercised over the full prelude+kernel, not just the tiny witness. Two new witness fixtures (examples/new_{rawbuf_size_only,counter_user_adt}.ail); #49 reuses the existing loop_recur_str_binder_no_leak_pin.ail. Deviations from the plan, all forced by ground truth and verified against the live code before commit: - FnDef.export is Option<String>, not bool — dropped from MirDef (the plan's note allowed this fallback). Codegen reads FnDef.export directly, unaffected. - fn_param_types did not exist — lifted the param-type extraction into a shared pub(crate) fn and rewired both mono.rs sites (collect_mono_targets, collect_rewrite_targets) to it, so the param-type source cannot drift between mono and lower_to_mir. The helper unwraps a top-level Forall then reads Type::Fn.params — identical to the inner_ty extraction it replaces; the early-return non-fn guard is preserved at both sites. Behaviour-preserving (whole suite green; this is the only edit to existing mono behaviour). - lower_module mirrors two more mono.rs scaffolding rules the plan under-transcribed: skip intrinsic-bodied fns (they are signature-only; lowering them would hit synth's Term::Intrinsic guard) and seed env.current_module + env.globals + env.imports per module so synth's Var lookup resolves post-mono specialisations (e.g. compare__Int) in the prelude. - The #53 pin asserts the lowered (new Counter 42) init carries ty Counter, not that it is an MTerm::New: a monomorphic `new` over a user ADT is desugared to a dotted call `(app Counter.new 42)` before lower_to_mir runs (desugar.rs:1078-1098), so it lowers to MTerm::App. MTerm::New survives only for a polymorphic `new` carrying a written NewArg::Type (the #51 RawBuf path, covered by the rawbuf pin). The pin's intent — ty-fill correctness — is preserved; the structural variant is mir.2/mir.5 territory. - ailang-mir uses workspace-inherited Cargo fields for consistency with the existing crates (added it to [workspace.dependencies]). refs #49 |

iter raw-buf.2-kernel-rename (DONE 2/2): ailang-kernel-stub → ailang-kernel family-crate (refs #7)
Pure crate rename, zero behavioural change. ailang-kernel-stub becomes
the ailang-kernel family-crate: a re-export hub (src/lib.rs) plus one
submodule per kernel-tier module (today only kernel_stub:
src/kernel_stub/{mod.rs, source.ail}). raw-buf.3 plugs raw_buf in as a
sibling submodule; this iter only builds the home.
Task 1 (atomic — the rename breaks the build until every site is
threaded):
- git mv crates/ailang-kernel-stub → crates/ailang-kernel.
- Carved the STUB_AIL Form-A body verbatim (byte-identical, verified
via diff against HEAD's raw string) into src/kernel_stub/source.ail,
loaded by mod.rs via include_str!. The answer (intrinsic) fn is
byte-preserved — its INTERCEPTS bijection partner stays pinned.
- lib.rs is now the hub: `pub use kernel_stub::SOURCE as STUB_AIL;`.
The public symbol STUB_AIL is preserved, so ailang-surface and the
bijection test bind to it unchanged.
- 8 compile sites threaded across 6 files: Cargo package name,
workspace member + dep-alias, ailang-surface dep, loader.rs
use-paths (ailang_kernel_stub → ailang_kernel). Cargo.lock
auto-regenerated.
Task 2 (doc/ledger honesty, no build impact):
- design/INDEX.md, CLAUDE.md code-layout row + lockstep-pair row,
design/models/0007 ×2 — crate-path strings updated to the new
ailang-kernel/src/kernel_stub path.
- Scope note: the spec's raw-buf.2 Components row named only
design/INDEX.md + the CLAUDE.md code-layout row. plan-recon found two
more present-tense crate-path refs (CLAUDE.md:312 lockstep row,
model 0007:8/235). Folded them in per the honesty-rule — a rename
that leaves stale present-state paths is an incomplete rename.
Path-only; the retirement narrative stays for raw-buf.4.
The AILang module name kernel_stub (the Form-A string + parse_kernel_stub
fn) is deliberately unchanged — only the crate identifier moved.
Verification (orchestrator, this session): cargo build --workspace
clean; cargo test --workspace 669 passed / 0 failed / 2 ignored
(baseline held exactly — no test added/removed). Carve byte-identity
confirmed by diff; no stale ailang-kernel-stub / ailang_kernel_stub
refs remain in-tree (git grep, excl. history + lockfile). The four
rename-invisible ratifiers (kernel_stub_module_round_trips,
intercepts_bijection_with_intrinsic_markers, .ll snapshots,
workspace_pin) all green via the preserved re-export.

iter prep.3-kernel-tier-modules (DONE 9/9): kernel-tier modules + param-in + stub crate — closes #33
Terminal iteration of the kernel-extension-mechanics milestone. Ships
the four language-level mechanisms named in the spec's § Goal:
Module.kernel + TypeDef.param-in schema, their Form-A surface,
flag-driven kernel-tier auto-injection, and generic param-in checker
enforcement with a new diagnostic.
Schema (Tasks 1+2). Module gains a `kernel: bool` field
(skip_serializing_if = is_false), TypeDef gains a
`param_in: BTreeMap<String, BTreeSet<String>>` field
(skip-if-empty, kebab-renamed to "param-in"). Both fields are
strictly additive — every pre-existing fixture's canonical-JSON hash
is bit-stable except `prelude.ail`, which intentionally gains
`(kernel)`. The struct-literal sweep covered ~104 Module sites and
~35 TypeDef sites across the workspace; the additive serde-default
covers JSON deserialise paths, only Rust struct literals broke.
Form-A surface (Tasks 3+4). `(kernel)` is a bare module-header
attribute; `(param-in (a Int Float) (b Str))` is one outer
TypeDef-body clause carrying one or more inner var-lists (OQ1
decision — mirrors `(ctors …)`, one parser arm, deterministic
BTreeMap iteration). Both round-trip Form-A → JSON → Form-A
bit-identical.
Workspace-load migration (Task 5). The hardcoded `&["prelude"]`
literal at loader.rs:108 became a `modules.values().filter(|m|
m.kernel)` derivation; `parse_prelude()` injection stays because
the prelude has no on-disk manifest in user workspaces. Prelude
now carries `(kernel)` in its source, so the new filter picks it
up automatically. Code-path migration only — observable behaviour
is identical (prelude_free_fns.rs stays green). prelude hash
re-pinned (af372f28c726f29f) with Honesty-Rule provenance comment.
WorkspaceLoadError::ReservedModuleName diagnostic prose
repurposed: any built-in kernel module name is reserved
(currently prelude + kernel_stub), not specifically prelude. CLI
mapping at main.rs updated in lockstep.
Stub crate (Task 6). New `crates/ailang-kernel-stub/` is a
zero-dependency leaf crate carrying only `pub const STUB_AIL:
&str` with the Form-A source of the kernel_stub module (one
parametric TypeDef with param-in, one ctor). The parse hop —
`parse_kernel_stub()` — lives in ailang-surface next to
parse_prelude, keeping the crate-dependency graph acyclic
(`ailang-surface → ailang-kernel-stub → ailang-core`, no
back-edge). The stub is injected unconditionally in all builds as
the ratifying fixture for the kernel-extension mechanism; future
base extensions may add more or retire the stub. Drift-pinned by
`kernel_stub_module_round_trips`.
Checker (Task 7). New `CheckError::ParamNotInRestrictedSet`
variant + code() + ctx() arms + enforcement in
`check_type_well_formed`'s Type::Con arm — generic, data-driven
from the TypeDef, mentions no specific extension type. Two
in-source tests pin both the rejection (`Str` outside `{Int,
Float}`) and the acceptance (`Int` inside) paths.
Workspace-load integration tests (Task 8). New
`workspace_kernel.rs` integration-test crate with three tests:
auto-import without explicit `(import …)` declaration, two
kernel-tier modules co-load, explicit-import-overrides-auto-
import precedence preserved. Loader is import-tree-only so the
auto-import tests use a bridge module that brings the kernel
module into the workspace via the import graph — docstring
captures the reachability nuance for future readers.
Doc-state transitions (Task 9). INDEX.md kernel-extensions row
annotation transitions from "design accepted 2026-05-28; impl in
progress" to "mechanisms milestone closed 2026-05-28; raw-buf and
series milestones pending". Whitepaper STATUS + auto-import +
param-in sections transitioned forward→present for shipped
mechanisms; forward-tense survives only in sections describing
the still-pending raw-buf/series milestones (per Honesty-Rule).
data-model contract gains anchor blocks for both new schema
fields.
Side-effect: every binary's IR snapshot now contains ~52 lines
for `drop_kernel_stub_StubT` because the stub is auto-injected
into every workspace load. Snapshots refreshed; e2e expects 4
modules per workspace (prelude + kernel_stub + entry + zero or
more user modules) instead of the previous 3.
Plan defects scrubbed in the implementation (folded back into
the planner template via the planner's self-review checklist
next time): Task 4 sample test src used fictional
`(ctors (MkT a))` list form (project grammar is per-`(ctor MkT
a)`); Task 6 original wiring would have created a cycle
ailang-surface → ailang-kernel-stub → ailang-surface (inverted —
stub crate is zero-dep, parse hop lives in surface); Task 7 in-
source tests referenced a fictional `check_type_in_module`
helper (used the existing Workspace + check_workspace
convention); Task 8 first integration test expected loader to
auto-load kernel modules from disk (loader is import-tree-only;
tests use a bridge module).
Concern-5 fix folded in pre-commit: workspace.rs ReservedModuleName
doc-prose initially said "in test/dev builds" for kernel_stub —
but stub is unconditionally injected in all builds. Doc copy
tightened to present-state per Honesty-Rule.
Stats: 0 spec-review-loops, 0 quality-review-loops, 2 sweep-script
retries on Task 2 (brace-depth bug on nested vec![Ctor{…}],
recovered via per-file checkout + rewritten anchor-on-existing-
field sweep), 1 e2e-snapshot refresh on Task 6.

convention: counter-prefix file naming across docs/specs/, docs/plans/, design/contracts/, design/models/
All 176 files in the four accumulating directories now use a zero-padded 4-digit counter prefix that reflects creation order (`NNNN-slug.md`). The counter is assigned per directory in strict git-log creation order; ties broken alphabetically by original name. The old `YYYY-MM-DD-` prefix on docs/specs/ and docs/plans/ files is dropped — the date is recoverable from git log and the counter carries the ordering. A file's counter is stable for the life of the file: never reassigned, never reused, never compacted. Deleted files retire their counter; subsequent files do not fill the gap. This is the property that lets cross-references stay literal — refs use the full filename including the counter (`design/contracts/0007-honesty-rule.md`) so they grep cleanly and resolve directly without a glob step. 313 cross-references updated across .md/.rs/.toml/.c/.json files (test pins, include_str! paths, design-INDEX entries, baseline notes, runtime C comments, inter-contract markdown links incl. bare basename and `../models/foo.md` forms). CLAUDE.md gets a new "File-naming convention" section spelling out the rule and rationale. skills/brainstorm/SKILL.md and skills/planner/SKILL.md updated so new spec/plan creation produces counter-prefixed names from the start. The full test suite (cargo test --workspace) passes. |

iter rt.1: roundtrip-invariant audit tests — 3 new tests, all PASS first-shot
Three new reader-only tests pin the .ail.json / .ailx bijection plus AST-variant coverage. All three passed first observation across the current corpus — no roundtrip, schema-coverage, or CLI-drift gaps surfaced. - every_ailx_fixture_matches_its_json_counterpart (replaces the 3-pair handwritten exhibits): 57 paired .ailx fixtures pass. - every_ast_variant_is_observed_in_the_fixture_corpus (new): 34/34 AST variants exercised across 136 fixtures; exhaustive matches without _ wildcard so AST drift fails the build. - cli_render_then_parse_preserves_canonical_bytes_on_every_fixture (new): 136 fixtures round-trip through ail render → tempfile → ail parse with BLAKE3 identity on canonical bytes. No production code, no DESIGN.md changes (those follow in later iterations). Tests are pure readers of the repo per spec acceptance #7 — tempfile crate added as workspace dep for the CLI roundtrip's intermediate file outside the repo. |

prose: human-readable projection renderer (iter 20a)
New crate ailang-prose with one public fn module_to_prose(&Module) -> String. Rust-flavour with braces, =>-match-arms, mode keywords (own/borrow), effects as trailing 'with IO', Cons(1, Nil) ctor form, /// doc strings. Lossy projection where the LLM can re-derive: (con T) wrap, (fn-type ...) wrap, (term-ctor ...) wrap. Load-bearing semantic detail stays visible (modes, effects, clone, reuse-as, doc strings, type annotations, tail flag). CLI: 'ail prose <file.ail.json>' prints the projection. 3 snapshot fixtures + 28 unit tests. 215-line .ail.json reduces to ~18 lines of legible source. 20b queued: infix arithmetic, paren elision, let-inlining, do prettify. |

Iter 14c: ailang-surface ships — form (A) parser + pretty-printer
Strictly additive new crate per Decision 6 architectural pin. JSON-AST stays the source of truth; ailang-surface is one producer/consumer of ailang_core::ast::Module values. ailang-check and ailang-codegen unchanged. Crate contents: - src/lex.rs (~264 LOC): 3-rule lexical core. Whitespace and parens delimit tokens; semicolon to EOL is comment; first-character classifier (digit -> int, " -> string, else -> ident). - src/parse.rs (~1041 LOC): hand-written recursive descent. One Rust fn per EBNF production. No parser-combinator dep. - src/print.rs (~371 LOC): deterministic pretty-printer. Round-trip contract with parse() is the surface's correctness gate. - tests/round_trip.rs (~128 LOC): integration test runs every examples/*.ail.json fixture through print -> parse -> canonical JSON, asserts canonical-byte equality with the original. Two AST-driven form widenings beyond the 14b sketch (both folded into DESIGN.md Decision 6): - lam-term carries (typed name type) params, ret type, and optional effects (Term::Lam has parallel param_tys/ret_ty/ effects fields). - import-clause admits (import name (as alias)?) (Import.alias is Option<String>). Production count ~28, under 30-rule budget. Constraint 1 (formalisable for foreign LLM) intact. Verification: - cargo build --workspace green. - cargo test --workspace: 76 tests green (was 64; +9 surface unit, +2 round-trip integration). All 17 fixtures round-trip byte-identical at canonical level. 3 hand-written .ailx exhibits parse to canonical JSON identical to their .ail.json siblings. - cargo doc --no-deps zero warnings (DESIGN.md item 6 invariant). Manual smoke test (ail parse → ail run): hello, box, list_map_poly all produce expected output through the form-(A) authoring lane end-to-end. CLI: ail parse <file.ailx> [-o <file.ail.json>]. .ail.json remains a first-class input to every existing subcommand. Plan 14d: stdlib (std_list.ailx with length/filter/fold/concat/ reverse/head/tail), authored in form (A) from day one. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
