iter intrinsic-bodies.1-mechanism (DONE 8/8): Term::Intrinsic leaf + cross-crate wiring (refs #9)
First iteration of the intrinsic-bodies milestone. Introduces the
Form-A `(intrinsic)` body marker as a new leaf AST term and wires it
through surface, checker, codegen, and a kernel_stub ratifier. The
prelude migration + hard-lockstep pin + dead-path removal are .2.
What landed (8 tasks):
Task 1 — Term::Intrinsic unit variant (ast.rs), tag "t":"intrinsic"
via the enum's rename_all=lowercase. Additive: no existing fixture
carries it, hashes bit-identical. In-core exhaustive-match arms
(canonical/hash/visit/pretty/desugar/workspace) added as leaves.
Task 2 — surface parse + print: (intrinsic) as a fn body-slot clause
and a lambda positional body, mapped to/from Term::Intrinsic.
Task 3 — cross-crate walker sweep (check/codegen/prose/ail-main):
leaf no-op/identity arms at every no-wildcard Term match the
compiler flagged.
Task 4 — checker: new Env.current_module_kernel_tier flag (m.kernel
|| m.name=="prelude"), set alongside current_module. A def whose
body is intrinsic (top-level fn OR instance-method lambda, via the
shared is_intrinsic_body helper) is checked signature-only; an
intrinsic body outside kernel-tier/prelude is rejected with
intrinsic-outside-kernel-tier.
Task 5 — codegen: an intrinsic-bodied fn routes through the existing
try_emit_primitive_instance_body / intercepts::lookup path; if no
intercept fired it is an internal error, never a lower_term
fallthrough. lower_term and the synth walker get Term::Intrinsic
internal-error arms (an intrinsic body reaching either is an
escape bug).
Task 6 — answer intercept (ret i64 42) registered in INTERCEPTS;
the `answer : () -> Int` intrinsic added to STUB_AIL;
examples/kernel_intrinsic_smoke.ail added so schema_coverage
observes Term::Intrinsic in the examples/ corpus.
Task 7 — E2E ratifier: examples/kernel_answer.ail calls
kernel_stub.answer and prints 42; answer_intrinsic_builds_and_runs_printing_42
asserts it end-to-end (source → native).
Task 8 — design/contracts/0002-data-model.md gains the
{ "t": "intrinsic" } Term entry + fn/lam prose; form_a.md grammar
note updated.
Verification:
cargo test --workspace → 669 passed, 0 failed (baseline 667 +2:
intrinsic_in_user_module_is_rejected, answer_intrinsic_builds_and_runs_printing_42).
bench/check.py + bench/compile_check.py → 0 regressed.
Reject E2E (subprocess ail check --json, exit 1, code
intrinsic-outside-kernel-tier) GREEN.
Round-trip + hash pins GREEN — Term::Intrinsic is additive, no
existing fixture carries it, no hash moved.
Three implementation completions beyond the plan (all behaviour-
preserving, surfaced during execution):
1. The signature-only skip had to apply at the mono pass's two
synth-on-body re-entry sites (collect_mono_targets,
collect_residuals_ordered), not only check_fn — else an intrinsic
body hits synth's Term::Intrinsic internal-error guard. Repaired by
extracting the shared crate::is_intrinsic_body helper and applying
it at all three synth-on-body paths. Not a representation surprise:
the same signature-only treatment, more call sites.
2. The compiler-enumerated exhaustive-match set was broader than the
plan's named grep set (the plan anticipated this and made the sweep
compile-driven). Extra leaf arms in core desugar/workspace, check
reuse-as + qualify_workspace_term, codegen synth_with_extras,
ail/src/main.rs, and four test targets.
3. Fixture corrections: emit_answer needed the body-close
(block terminator) the plan snippet omitted; kernel_answer.ail's
main is (ret Unit)(effects IO) using (app print ...) since
io/print_int does not exist (the plan flagged this for the
implementer to resolve against real effect-op names).
IR snapshots (hello/sum/list/max3/ws_main.ll) refreshed: purely
additive @ail_kernel_stub_answer fn+adapter+closure, emitted into
every workspace exactly as the pre-existing @ail_kernel_stub_new
already was (kernel_stub is auto-injected; confirmed new was present
in the pre-iter hello.ll baseline). No user-fn IR changed.
The .2 iteration migrates the 18 prelude dummy bodies to (intrinsic),
upgrades registry_contains_all_legacy_arms to a source<->registry
bijection pin, and removes the dead body-lowering path.

iter prep.2-term-new-construct (DONE 4/4): Term::New AST + Form-A surface + checker + drift — closes #32
Second iteration of the kernel-extension-mechanics milestone. Ships
the `new` Form-A keyword + `Term::New { type_name, args: Vec<NewArg> }`
AST variant + `NewArg::Type|Value` enum end-to-end through schema /
surface / checker, with two new diagnostics
(`NewTypeNotConstructible`, `NewArgKindMismatch`), a new arm in
prep.1's workspace-wide normalisation pre-pass `qualify_workspace_term`
that rewrites bare `Term::New.type_name` to qualified form
(symmetric to the existing `Term::Ctor` arm), and the data-model.md
+ form_a.md anchor additions. Codegen out of scope per spec; codegen
sites get `CodegenError::Internal` arms naming the raw-buf milestone
as the carrier.
Verification:
- `cargo test --workspace`: 654 tests passing, 0 failed.
- 3 new in-source checker tests pin the elaboration paths:
`new_resolves_via_type_scope` (the spec's worked Counter example
checks cleanly), `new_type_not_constructible` (missing `new` def
in home module fires the new diagnostic), `new_arg_kind_mismatch_value_where_type`
(kind-mismatch detection).
- 2 new schema-drift pins (`term_new_round_trips`,
`term_new_type_arg_round_trips`) ratify the JSON byte shape:
`{"t": "new", "type": "<TypeName>", "args": [{"kind": "type"|"value",
"value": ...}]}`.
- 1 new surface round-trip pin exercises mixed-kind args through
Form-A → JSON → Form-A.
- 44+ exhaustive Term-match sites across 24 files extended with
`Term::New` arms — workspace-wide cargo build clean.
Concerns documented inline:
- `crates/ailang-core/tests/schema_coverage.rs` deliberately does
NOT register `VariantTag::TermNew` in the `EXPECTED_VARIANTS`
set. The coverage test asserts every declared variant is
observed in the .ail fixture corpus; no .ail fixture in the
current tree emits `"t": "new"` (codegen-runnable Term::New
programs require the raw-buf milestone's plugin registry).
Registering would fail the coverage check. The `visit_term` arm
IS extended (compile-forced); only the enum registration is
deferred. Inline rationale in the source. Future milestone that
ships a Term::New fixture extends both sides.
- `crates/ailang-surface/src/print.rs` `write_term` Term::New arm
was added in Task 1 (not Task 2 as planned), because without it
ailang-core's tests fail to compile (the surface crate is in
the dependency graph of ailang-core's test binaries). Task 2's
round-trip pin verified the arm's correctness.
- Task 3 (synth elaboration) needed one implementer re-loop: the
first attempt over-qualified within-module type-references via
`qualify_local_types` on `new`'s signature when the home module
was the calling module itself. Fixed by skipping qualification
when `home_module == env.current_module`.
Architectural composition with prep.1: `Term::New` joins
`Term::Ctor` as a `type_name`-bearing site that goes through
`qualify_workspace_term`'s bare→qualified rewrite before the
checker sees it. The checker's `synth` arm for `Term::New`
therefore receives an already-qualified `type_name` (or a local
bare name for same-module construction).
Milestone status: kernel-extension-mechanics (Gitea #6) advances
2/3 iters. Next: prep.3 (kernel-tier modules + param-in), issue #33.

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 design-md-rolesplit.1 (DONE 9/9): DESIGN.md -> design/ ledger role-split
The 3020-line docs/DESIGN.md is replaced by the design/ ledger:
design/INDEX.md (sole addressable spine, typed Contracts+Models tables,
polymorphic links — prose file OR authoritative source //!), 14
design/contracts/*.md test-linked invariants + 3 source-link-only
contracts (mangling/env-construction/qualified-xref, no prose file —
code is SoT), 5 design/models/*.md whitepapers, and
docs/journals/2026-05-19-design-decision-records.md (the
relitigation-guard archive — every why/rejected/does-not-do/rollback/
empirical ### moved out at ###-granularity). Clean cut: git rm
docs/DESIGN.md, no stub.
RED-first crates/ailang-core/tests/design_index_pin.rs — the 4-clause
anti-regrowth spine (DESIGN.md-gone / every-INDEX-link-resolves /
every-contract-names-a-resolvable-ratifier /
contracts-carry-no-decision-record-prose) — demonstrably RED before,
GREEN after. Build-atomic by task ordering: design_schema_drift.rs's
include_str! (the only compile-time consumer) retargeted to
design/contracts/data-model.md BEFORE the deletion; its
## Data model/## Pipeline slicer dropped (a simplification the split
enables). 2 NoInstance diagnostics + 2 lockstep E2Es retargeted to
design/contracts/{float-semantics,typeclasses}.md. ~12 agent reading
lists + 5 SKILL bodies + CLAUDE.md + skills/README.md + ~25
code/C/.ail/spec comment xrefs retargeted; OQ7 dangling 'Iter 13b'
cite deleted (no forward target — a pointer would be fiction).
honesty-rule.md rewritten so the rule names the new home
(rationale->journals), resolving the recon-found internal
contradiction; the two docs_honesty_pin.rs:70,72 pinned phrases kept
verbatim+contiguous.
Boss-verified independently: cargo test --workspace 646 passed /
0 failed; design_index_pin 4/4; acceptance grep CLEAN of live
DESIGN.md refs (residuals = only the spec-mandated clause-4
deletion-enforcer). 2 DONE_WITH_CONCERNS routed to the mandatory
milestone-close audit: (a) str-abi.md:23 '(iter str-concat,
2026-05-13)' provenance stamp trips advisory architect_sweeps Sweep-1
— Boss-confirmed byte-identical to DESIGN.md@deeffb1:2062-2065, a
faithfully-migrated PRE-EXISTING anchor (regexes verbatim, only path
retargeted), NOT split-introduced — RATIFY-or-tidy at audit; (b) a
now stale-direction intra-prose 'see Str ABI below' cross-ref in
float-semantics.md — audit-adjudication candidate. Plan defect noted:
Task 9 Step 4's verbatim acceptance grep used a ^./ anchor not
matching the system's grep -rIn output; substance re-verified CLEAN.

iter remove-mut-var-assign.1: atomic removal of mut/var/assign
mut/var/assign removed from AILang entirely and atomically. Deleted: Term::Mut/Term::Assign/struct MutVar; the three Form-A keywords + parse_mut/parse_assign + grammar EBNF; the 4 mut CheckError variants; the mut_scope_stack synth threading (param dropped from synth + every internal/external/test caller); the two lower_term arms; and every exhaustive no-_ Term::Mut/Term::Assign match arm across 17 source files — cut in lockstep with DESIGN.md, fixtures, the drift trio, carve-out and roadmap so the schema is honest at every commit. No catch-all wildcard introduced (verified). loop/recur + let/if are the surviving forms. The shared codegen alloca machinery survives (loop reuses it): mut_var_allocas renamed binder_allocas (representation-only, loop codegen byte-identical) and the shared Term::Lam escape guard simplified to !loop_stack.is_empty() with the loop half (LoopBinderCapturedByLambda) byte-equivalent. Feature-acceptance applied inverted: the removed feature fails clause 2 (redundant) and clause 3 (IS the iterated-mutable-state bug class). Behaviour preservation is executable: mut_counter/mut_sum_floats still print 55 after the faithful let/if rewrite. The removal is made executable by the new mut_removed_pin.rs (4 must-fail pins). Independent verification: cargo test --workspace 605/0, zero residual mut symbols in any crate source, loop/recur non-regression all green (55 / 500000500000 / infinite-compiles / the lambda_capturing_loop_binder pin), roundtrip_cli PASS. One DONE_WITH_CONCERNS: a 4th recurrence of the recon-undercount class (in-source mod tests + a drift-pin fn + 5 orphaned mut .ail.json carve-outs + a non-enumerated E0599); all resolved within implementer remit, no behaviour change. Milestone-close audit then fieldtest remain. spec docs/specs/2026-05-18-remove-mut-var-assign.md (grounding PASS) plan docs/plans/remove-mut-var-assign.1.md |

iter it.1: loop/recur additive — Term::Loop/Term::Recur/LoopBinder end-to-end
Iteration-discipline milestone, 1 of 3. Adds named loop + recur as strictly-additive first-class AST nodes: parse/print/prose/serde/ round-trip/schema lockstep, typecheck (binder typing + recur arity/type unification via loop_stack threaded as mut.2's mut_scope_stack; recur-tail-position via verify_loop_body), codegen (loop-header + one phi per binder; recur back-edge br with a NEW parallel block_terminated setter; lambda-boundary loop_frames save/restore). Four Recur* CheckError variants. Strictly additive: zero deletions touch tail-app/tail-do or the seven existing block_terminated sites — this is what makes the destructive it.3 safe. recur synth = fresh metavar (resolves the plan's flagged Type::unit() risk). loop_counter->55, loop_in_lambda->49, four negatives fire, tail-app byte-identical, cargo test --workspace green.

iter mut.1: AST extension + Form A surface for local mutable state
First iteration of the mut-local milestone (foundation step on the
Stateful-islands roadmap path). Lands the schema + surface tier:
Term::Mut, Term::Assign, and the nested MutVar struct become
first-class AST nodes that round-trip cleanly through Form A.
Typecheck and codegen recognition are deferred to mut.2 and mut.3
per the spec's out-of-iteration boundary; reaching either dispatch
entry point with these variants produces CheckError::Internal /
CodegenError::Internal with a 'deferred to iter mut.{2,3}' message.
Concretely:
- crates/ailang-core/src/ast.rs: two new Term variants behind
#[serde(tag = 't')]; pub struct MutVar { name, ty, init } adjacent
to Arm. Two canonical-bytes pin tests for the explicit-empty-vars
serialisation and the assign round-trip.
- ~25 substantive Term-walker arms across ailang-core/desugar,
ailang-core/workspace, ailang-check (lib + lift + linearity + mono
+ pre_desugar_validation + reuse_shape + uniqueness),
ailang-codegen (escape + lambda + lib), ailang-prose, and
crates/ail/src/main.rs. Universal policy: substantive recurse-into-
children at every site; only the two dispatch entry points
(synth in ailang-check, lower_term in ailang-codegen) stub with
Internal-error. One test-side walker arm in
crates/ail/tests/codegen_import_map_fallback_pin.rs not
enumerated by the plan was added as well (defensive recursion).
- ailang-surface: parse_mut + parse_assign helpers; Term::Mut
body desugared from a flat statement sequence into a right-folded
Term::Seq chain inside the JSON-AST. Print arms in print.rs match
the parser convention. EBNF prologue + crates/ailang-core/specs/
form_a.md productions updated. Four new parser pin tests cover
the empty-mut, single-var, body-required, and vars-only-no-body
cases.
- Drift + coverage tests extended: design_schema_drift.rs adds two
exemplars + match arms; schema_coverage.rs adds two VariantTag
entries + EXPECTED_VARIANTS + visit_term arms; spec_drift.rs adds
two exemplars + match arms. DESIGN.md §'Term (expression)' gets
jsonc-blocked schemas for the two new variants.
- examples/mut.ail: six-fn round-trip fixture exercising empty mut,
single-var, two-var, nested-shadow, and the four supported scalar
return types (Int, Float, Bool, Unit). The round_trip auto-glob
and schema_coverage corpus walker both pick it up.
Plan deviation: the plan named lib.rs:2572 as the typecheck
dispatch stub site, but that line is actually verify_tail_positions
(substantive walker). The real dispatch is synth (3403-area, stub
at 3489); the orchestrator routed correctly.
Tests: 564 → 579 green; cargo build green; round-trip green for
the new fixture; all drift + coverage tests green.

iter form-a.1 (Tasks 1-5): additive phase + relocation
First half of the form-a-default-authoring milestone-close iter (Boss-decided strategy C, big-bang). All five tasks DONE; cargo test --workspace green at every per-task boundary. T1 — Add three new tests: - parse_is_deterministic_over_every_ail_fixture (round_trip.rs) - cli_parse_then_render_then_parse_is_idempotent (roundtrip_cli.rs) - carve_out_inventory.rs (new file; #[ignore]'d until T8 deletion) T2 — Bulk-render the 99 missing examples/<stem>.ail files via `ail render`. Corpus 58 .ail (pre-iter) -> 157 .ail. Eight .ail.json carve-outs (7 §C4(a) subject-matter + 1 §C4(b) prelude) preserved. One re-loop triggered: load_workspace prefers .ail siblings since ext-cli.1, so the newly-rendered imports broke seven Group-A entries whose JSON entry-paths now resolved imports to fresh .ail. Repair: pre-emptive forward-pull of five T3 migrations + 4 transient #[ignore]s on workspace.rs mod tests (cleanly relocated in T5). T3 — 14 Group-A test files migrated from ailang_core::load_workspace to ailang_surface::load_workspace + .ail paths. Carve-out lines preserved verbatim (7 sites in typeclass_22b2.rs / typeclass_22b3.rs). T4 — 12 Group-B test files: bulk regex flip on build_and_run / build_and_run_with_alloc / build_and_run_with_rc_stats call sites (~70 e2e.rs invocations + 11 subprocess sites). Four files mis-classified Group-A as Group-B in plan recon (mono_hash_stability, prelude_free_fns, print_mono_body_shape, show_mono_synthesis); two files mis-classified Group-B as Group-A (mono_recursive_fn, mono_xmod_qualified_ref). Migrated per actual shape, not plan label. T5 — Relocated #[cfg(test)] mod tests from production source to integration test crates with ailang-surface dev-dependency: - crates/ailang-core/tests/hash_pin.rs (10 tests from hash.rs) - crates/ailang-core/tests/workspace_pin.rs (10 non-carve-out tests from workspace.rs) - crates/ailang-codegen/tests/eq_primitives_pin.rs (3 tests from codegen/src/lib.rs:3717-3799) - ailang-prose/tests/snapshot.rs migrated (helper + 8 fixtures) to .ail + ailang_surface::load_module Carve-out tests in workspace.rs mod tests preserved in-place (3× 22b2 + 3× ct1 = 6 tests). Tempdir-based loader-mechanism tests (3 sites) also preserved — they don't consume examples/. Tests: 560 passed, 0 failed, 4 ignored (was 558 + 3 T1 new - 1 transit carve_out_inventory #[ignore] = 560 active). Tasks 6-12 (bench-driver suffix flips, e2e diff-test rewrite + 4 additional raw-JSON-inspect handlers, .ail.json deletion, retiring obsolete roundtrip tests + schema_coverage corpus flip, §C3 DESIGN.md restatement, §A4 doctrine edits, WhatsNew + roadmap strike) ship in the next dispatch on this iter ID. Known debt inherited to T6-12: 4 raw-JSON-inspect tests in e2e.rs (borrow_own_demo / reuse_as_demo / render_parse_round_trip_canonical / ail_run_accepts_ail_source_with_same_stdout_as_ail_json dual-form smoke) need rewrite or #[ignore] before T8 deletion; recorded in journal Concerns + Known debt sections. |

iter 24.tidy: close 5 actionable drift items from audit-24
Documents the three iter-24.3 strengthenings as load-bearing invariants and tightens two error-handling sites: T1: DESIGN.md gains new subsection §Cross-module references in synthesised bodies (between Resolution-and-monomorphisation and Defaults-and-superclasses) documenting three invariants installed in iter 24.3 — (1) MonoTarget::FreeFn::type_args carries canonical types post-collection via normalize_type_for_lookup; (2) post-mono synthesised body cross-module refs may bypass the source template's import_map (codegen falls back to module_user_fns / module_def_ail_types); (3) FreeFnCall synth pushes one ResidualConstraint per declared forall-constraint with rigid vars substituted by fresh metavars. T2: codegen_import_map_fallback_pin.rs (integration test) asserts the synthesised prelude.print__<IntBox> body references show_user_adt.show__<IntBox> AND prelude module's imports do not contain show_user_adt — proving the cross-module ref bypasses import_map at codegen. T3: polyfn_dot_qualified_branch_pin.rs (integration test) asserts bare-name print f (f : Int -> Int) fires exactly one no-instance diagnostic at typecheck with zero unknown-variable diagnostics — proving the bare-name resolution reaches the dot-qualified synth branch where the constraint-residual push fires. T4: check/lib.rs:2858 unwrap_or_default() replaced with .expect() carrying the registry-coherence message — class_methods index drift now surfaces explicitly rather than rendering NoInstance with an empty method name. T5: mono.rs gains apply_subst_and_normalize helper (Option<Type> return) extracted from two byte-identical call sites at collect_mono_targets and collect_residuals_ordered. Each call site retains its own rigid-var / unit-default policy in the None arm (site 1: rigid → has_rigid+break, unbound → Type::unit; site 2: non-concrete → Type::unit). Byte-identity invariant on mono-symbol hashes enforced by construction. Tests: 558 passed (was 556 + 2 new pins). No production semantic change — pure documentation + test pin + error-handling tightening + helper refactor. bench/cross_lang exit 0; bench/compile_check + bench/check exit 0 this run (latency.implicit_at_rc / latency.explicit_at_rc / bench_list_sum.bump_s noise envelope unobserved, lineage continues at 10th consecutive observation without firing this run). |
