fix(codegen): drop branch-consume-split owned params (#63 leg 3)
The last leg of the #63 drop-soundness cluster: an (own ...) heap param consumed on one match-arm / if-branch but live on a sibling was never dropped on the live path, leaking one slab per call. This was the residual live=2 leak in series_sma that kept the series headline from being leak-clean. Root: the per-fn aggregate consume_count (the worst-case max over all branches from uniqueness::merge_states) was codegen's only consume signal, and every owned-param drop site gated on it. A param consumed on SOME branch makes the aggregate >= 1, so every site skipped it — including the branch where it stays live. match and if share this root (if is first-class MTerm::If, not desugared to match). Mechanism (spec 0068): - CAPTURE: uniqueness retains the per-branch consume snapshots it already computes per branch and discarded at the max merge — new BranchConsume + infer_module_with_cross_branches (the aggregate-only infer_module_with_cross now delegates and drops the channel). - CARRY: additive MArm.consume / MTerm::If.{then,else}_consume, attached by lower_to_mir via a traversal-order cursor (post-order pop, kind- and exhaustion-asserts make a desync a loud panic; neutral for const bodies which uniqueness does not walk). The AST carries no node id, so the correspondence is the structural pre-order both walks share — pinned by branch_consume_maps_attach_to_matching_arms. - GATE: emit_leakclass_branch_param_drops fires a fall-through drop only for the leak class (branch_consume==0 AND aggregate>=1), in match arms + both if branches; the pre-tail-call dec switches its gate source from the aggregate to per-arm. The fn-return dec and arm-close pattern-binder dec are UNCHANGED. Safety: - Double-free: the drop sites partition by aggregate (==0 -> existing fn-return/pre-tail-call; >=1 -> new per-branch). Disjoint, so no param is dropped twice — no fn-return disable, no tail-position analysis. - Use-after-free: the checker rejects use-after-consume, so an aggregate>=1 param is provably dead past the construct (path-terminal drop, tail position irrelevant). - Type eligibility (found by the full-suite gate during implement; spec 0068 refined): the new agg>=1 site is the FIRST drop site that can reach a STATIC closure-pair param (a top-level fn ref like inc in Either.either, consumed on one arm, live on the other) — a .rodata constant with no rc-header. field_drop_call routes Type::Fn / static-Str / Type::Var to the bare ailang_rc_dec, which underflowed on it. The helper now drops only params with a real per-type heap-ADT drop fn (field_drop_call != "ailang_rc_dec"). Sound (no underflow) and leak-correct (a static closure/Str allocates nothing). Witnessed green by std_either_demo / std_list_demo / poly_rec_capture_demo. Verification: full workspace suite green (116 binaries); both new leak pins (if + match) and series_sma_no_leak_pin green at live=0; legs 1/2 pins still green; INTERCEPTS<->(intrinsic) bijection intact; no Pattern::Lit reject path added. The leg-3 helper's type precondition was applied inline by the orchestrator (a narrowing guard clause in an already-reviewed Task-4 helper, full context loaded) after the implement-orchestrator correctly surfaced the spec gap rather than papering over the regression. This clears the series_sma leak tail; the series milestone (#61) close stays a separate deliberate step (its end-to-end milestone fieldtest). closes #63 |

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(lang): eliminate the Implicit ownership default — totality + the drop-soundness it demasks (#55)
Deletes `ParamMode::Implicit`. `ParamMode` is now `{Own, Borrow}`:
every fn-type slot on every signature carries an explicit `own` or
`borrow`, no defaulted position survives anywhere (model 0008 §2,
spec 0062). The parser rejects a bare fn-type slot; `borrow-return`
and `borrow-over-value` reject at the signature; the corpus is
migrated to minimal-ownership modes (consumed ⇒ own, read-only-heap
⇒ borrow, value ⇒ trivial-own). The documented `Implicit`-ret-mode
leak is fixed: an owned heap return now drops exactly once (live=0,
acceptance criterion 5).
This was the easy half. Removing the default ACTIVATED a family of
drop paths that `Implicit` had silently skipped — the pre-cutover
language was leaking (and in places mis-dropping) here rather than
crashing, because an Implicit scrutinee turned the drop off. Making
the modes explicit (Own) turned those paths on and exposed two
latent-bug clusters, all fixed RED-first as part of this cutover:
Drop-soundness family (four legs):
A. lit-sub-pattern double-free — the desugar re-matched the same
owned scrutinee in the lit fall-through; fixed by grouping
consecutive same-ctor arms into one match (bind fields once),
in ailang-core desugar.
B. Cons-husk leak on non-tail arm bodies — the lit-sub-pattern
desugar rebound the owned scrutinee via `Let $mp = xs`, which
bumped consume_count and suppressed the existing fn-return
partial_drop. Fixed by not rebinding a bare-Var scrutinee
(one husk-freeing mechanism, not two).
C. polymorphic `drop_<T>` rc_dec'd monomorphised value fields —
the per-ADT drop fn was emitted once from the polymorphic
TypeDef, defaulting type-var fields to ptr and rc_dec'ing
inline Ints (segfault). Fixed with per-monomorph drop
functions (new ailang-codegen::dropmono): the drop set is
collected from the lowered MIR, value-type fields are skipped,
heap fields still freed once; monomorphic-concrete ADTs keep
their byte-identical un-suffixed drop symbol.
D. static Str literal passed to an `(own Str)` param — the
literal lowers to a header-less rodata constant; the callee's
now-active rc_dec read its length field as a refcount and
freed a static address (segfault). Fixed with the missing
fourth StrRep::Static→Heap promotion in lower_to_mir's App arm,
gated on Own mode (borrow args stay static, no regression).
over-strict-mode lint over-fired: it suggested `(borrow V)` for
value-typed params (which `borrow-over-value` rejects — own is the
only legal mode there) and fired on `(intrinsic)` bodies (whose
consumption the linearity walk cannot observe). Tightened to skip
both; contract 0008 updated to the narrowed firing scope.
Irreversible step — canonical-form hash reset (model 0008 §6,
acceptance criterion 6). Every signature now carries explicit modes,
so the hashable canonical JSON changed for every module. RATIFY:
the corpus-wide hash-pin reset (hash_pin, prelude_module_hash_pin,
mono_hash_stability, eq_ord_e2e, embed_export_hash_stable, the
ct4/iter*/loop_recur schema-extension pins) and the list ir_snapshot
golden were regenerated once, deliberately, as the intended one-time
consequence of removing the mode elision from the canonical form —
not a regression. Each regenerated hash verified deterministic across
two runs.
Also fixes a pre-existing latent failure surfaced by the verification
gate, unrelated to this cutover: the `every_contract_names_a_resolvable_
ratifying_test` resolver (design_index_pin) could not resolve the
" + " dual-link ratifying-test form (`uniqueness.rs + linearity.rs`)
that the #57 audit-close (

fix(examples): destructure partition_eithers result once (#57, 0064 iter 4)
Final iteration of spec 0064 (the #55-cutover hardening, #57). Closes class 4, the one genuine corpus bug among the four (not a false positive): std_either_list.partition_eithers projected both (app Pair.fst rest) and (app Pair.snd rest) from one owned `rest`. Pair.fst/snd are own-param projections that move a field out, so each consumes `rest` -> a genuine double-consume that universal linearity activation (#55) would correctly reject. The fix is a body rewrite (destructure `rest` once via (match rest (case (pat-ctor MkPair ls rs) …)) then dispatch on the head), NOT a check change -- the check is right. Latent until activation: partition_eithers' param is a bare (Implicit) slot today, so the check is skipped on it -- no RED->GREEN flip on the real fixture. The rewrite is a pre-emptive corpus fix. Its correctness rests on the unchanged 2 3 2 3 E2E output (std_either_list_demo, a semantically-identical partition) and on the new c4_double_consume must-stay-RED fixture, which -- with explicit modes, so the check is active today -- demonstrates the double-projection shape IS rejected. - examples/std_either_list.ail: partition_eithers Cons arm rewritten; doc updated (destructure-once, no longer "projections"). - examples/c4_double_consume.ail: must-stay-RED pin (the rejected shape), folded into a generalised harden_ownership_heap_double_consume_still_errors loop over {real_consume, c4_double_consume}. - examples/c4_rewrite.ail: stays-clean pin (the accepted destructure-once shape), added to harden_ownership_false_positives_are_clean. No hash-pin on std_either_list (verified); the e2e 2 3 2 3 output pin is the content pin and is preserved. No check/schema/codegen change. Verified: std_either_list checks clean; demo 2 3 2 3; both harden assertions green; cargo test --workspace green; bench/check.py 34/34, compile_check.py 24/24 stable. This is the last of the four #57 hardening classes. Spec 0064 is now code-complete: classes 1 (local fn-param modes), 2 (let-alias redirect), 3 (value-typed let-binder), and 4 (this) all shipped. The cycle is ready for audit; the #55 cutover precondition is met. refs #57 |

feat(check): let-alias borrow propagation via alias-redirect (#57, 0064 iter 3)
Third iteration of spec 0064 (the #55-cutover hardening, #57). Closes false-positive class 2: Term::Let walked its value in Position::Consume, so (let a t (match a …)) over a borrow-mode t consumed t at the binding and tripped consume-while-borrowed -- a let-alias of a borrowed value read in a borrow position is not a consume. Fix: the Checker gains a scoped aliases: HashMap<String,String>. A (let a t body) whose value is a bare Var resolving to a tracked binder records a -> root(t) for the body scope and skips the consume walk of the value. A new resolve_alias helper maps a name to its root, preferring a real binder at each chain step -- so an inner binder named `a` (nested let, pattern binder, lam param) automatically shadows the alias with NO change to with_binder/walk_arm/Lam (the shadowing is resolved centrally in the resolver, not at three scattered introduction sites). Every binder-state lookup keyed by name resolves through the map first: use_var, the App borrow bump + decrement (pushing the resolved root to `lent` so the decrement matches), callee_arg_modes, and the reuse-as source. Design calls (orchestrator): - Alias REDIRECT, not state clone (spec scope decision 3): consuming the alias marks the single root consumed, so a real double-consume through an alias is still caught. A clone would track two independent binders and miss it (unsound). Pinned by the new let_alias_of_owned_double_consume_still_errors unit test: (let a p0 (seq a p0)) over an own heap p0 still fires use-after-consume. - resolve_alias prefers binders -> shadowing needs no edits to the binder-introduction sites. Lower-risk than clearing aliases at each. - reuse-as source (linearity.rs:663) is resolved through aliases too: it is the 4th binder-state-reading site; the spec's Fix 3 named three illustratively. Without it, (reuse-as <alias> …) would mis-fire reuse-as-source-not-bare-var on what IS a Var. Faithful completion of Fix 3. The diagnostic now reports the resolved root name (the actual consumed resource), not the surface alias. Closes the design/contracts/0008-memory-model.md let-alias carve-out (was "has not shipped yet") and extends its Ratified-by trailer to name linearity.rs, where the propagation now lives -- a contract change riding with the feature that forces it. RED-first: examples/c2_let_alias.ail added to harden_ownership_false_positives_are_clean (RED: consume-while-borrowed on count's t); GREEN after. Verified: c2 RED->GREEN; 120 linearity unit tests green; the soundness test fires; harden false-positive + heap double-consume guards green; cargo test --workspace green; bench/check.py 34/34, compile_check.py 24/24 stable. Diagnostic-only; no schema/type/codegen change. Class 4 (partition_eithers body rewrite) remains for the final iteration of spec 0064. refs #57 |

feat(check): resolve local function-typed binder modes (#57, 0064 iter 2)
Second iteration of spec 0064 (the #55-cutover hardening, #57). Closes false-positive class 1: applying a local function-typed binder -- a HOF predicate param like std_list.filter's `p` -- treated its arguments as Consume because callee_arg_modes resolved only the global symbol table (locals returned an empty mode vec). So `(app p h)` with `p` a local (borrow ...) predicate consumed the heap element `h`, and reusing `h` in the kept Cons false-fired use-after-consume. Fix: BinderState gains fn_param_modes: Option<Vec<ParamMode>>, seeded at all three function-typed binder introduction sites via a new fn_modes_of helper (strip_forall + Type::Fn { param_modes }, None for non-fn / empty-modes so the caller falls through to globals): params and lam-params from their signature type (param_tys), let-binders from the LetBinderTypes table built in iter 1. callee_arg_modes reads a local Var callee's fn_param_modes before the global lookup (a local binder shadows a global -- correct lexical scope); the existing App arg-walk maps a Borrow mode to a borrow walk unchanged, so the fix is confined to the seeding + the one local-precedence read. Scope call (orchestrator): all three seeding sites, not just the param path that unblocks filter -- the point of this hardening cycle is to leave no latent class (the #57-from-0063-deferral lesson), and the extraction is uniform with the table already built. RED-first: examples/c1_local_hof.ail added to harden_ownership_false_positives_are_clean (RED: use-after-consume on filter_box's h) before the fix; GREEN after. Two in-source unit tests pin both seeding paths (param via signature, let via a hand-built table). Verified: c1 RED->GREEN; 119 linearity unit tests green; harden_ownership_false_positives_are_clean green (now c1 + c3); the heap-double-consume must-stay-RED guard still fires; cargo test --workspace green; bench/check.py 34/34, compile_check.py 24/24 stable. Diagnostic-only; no schema/type/codegen change. The stale `// Locals never carry fn-types in 18c.2` comment in callee_arg_modes (and the fn's doc header) is rewritten to the accurate local-precedence behaviour -- it sat in the replaced lines and directly contradicted the new path. Classes 2 (let-alias redirect) and 4 (partition_eithers rewrite) remain for later iterations of spec 0064. refs #57 |

feat(check): tee let-binder types, exempt value-typed let-binders (#57, 0064 iter 1)
First iteration of spec 0064 (the #55-cutover hardening, #57). Closes
false-positive class 3: a value-typed `let`-binder (e.g. a `Float`
result bound and read more than once) tripped `use-after-consume`
because the linearity walk installed every `let`-binder as a default
heap-tracked BinderState. Spec 0063 deferred exactly this class
("value-typed let-binders ... deferred until a corpus shape demands
it"); eqord_3_newton_sqrt.iterate's `(let xnew (app / …) …)` is that
shape.
Mechanism (the design call, user-delegated): the let-binder's type is
ALREADY computed at synth's Let arm and discarded. Stop discarding it.
synth gains a (def,binder)->Type out-param (LetBinderTypes, defined in
linearity.rs); the Let arm records `subst.apply(&v)`. The table is
allocated per-module in check_workspace, threaded through
check_in_workspace -> check_def -> check_fn/check_const/check_instance
-> synth, and passed (immutable) into check_module_with_visible ->
Checker. linearity's Term::Let seeds BinderState.is_value from the
table via the existing type_is_value predicate -- the same per-binder
flag #56 seeds at param/pattern/lam sites, now extended to the let
site. No schema change, no hash shift, no codegen change; the check
stays diagnostic-only.
Not a re-run of inference in the walk (ruled out by

feat(check): harden the ownership analysis for universal activation (0063)
The strict linearity check (use-after-consume / consume-while-borrowed, linearity.rs) runs today only on the ~45 of 258 all-explicit-mode fns; its activation gate skips any fn with a bare/Implicit param. Deleting ParamMode::Implicit (#55) would turn it on universally and surface ~21% false positives in two classes. This closes both, making the core ownership analysis sharp across the whole codebase for the first time — the precondition for #55. Diagnostic-only: no schema, no hash, no codegen change; the two existing diagnostic codes simply fire on a smaller, more correct set. Fix 1 — value-type exemption. A new is_value_type predicate (ailang-core::primitives) names the unboxed set {Int,Bool,Float,Unit}; BinderState gains an is_value flag seeded from the binder's locally available type (param signatures, ctor field types for pattern binders, lam typed-params), and use_var short-circuits the Consume arm for it. A value type has no refcount and is never consumed, so multi-read is always legal. Str is deliberately NOT in the value set, though is_primitive_name includes it: drop.rs:490-492 lowers only Int/Bool/Float/Unit to non-ptr; Str is a ptr, RC-dec'd, so a multi-consume of Str without clone is a real use-after-free. is_value_type is the Str-excluding subset of is_primitive_name, pinned by a unit test. is_heap_type and the over-strict-mode lint are left untouched (separate concern). Fix 2 — application is a borrow. Term::App walks its callee in Position::Borrow (was Consume). Applying a function value reads it; it stays live for further applications. Global fn-refs are untracked (no-op); a tracked function-typed binder (a HOF param) is no longer consumed by application. This fixes both the own-f-param use-after-consume and the borrow-f-param consume-while-borrowed in the recursion-passing HOF shape (map_int f t). Passing a function value as an arg is unchanged — it follows the callee param_modes. Scope decision: value-typed let-binders stay conservatively tracked as heap (their type is inferred, not annotated, and the linearity walk does not re-run inference). This is soundness-safe — over-strict, never unsound — and not a measured corpus shape; lifting it would need a full binder->type table out of the type-checker. Verification: all three false-positive classes reproduced today against explicit-mode fns and shipped as RED->GREEN fixtures (examples/fp_{value,hof,map}.ail); examples/real_consume.ail stays RED (heap double-consume still fires) to prove the exemption is type-gated. 715 workspace tests green; bench/check.py 0/34 and bench/compile_check.py 0/24 regressed. merge_states carries is_value so the flag survives branch merges. RED-first verified per task. closes #56 |

feat(codegen): StrRep loop-carried Str ⇒ Heap, close the #49 recur leak
mir.4 closes bug #49 (a heap-Str loop binder replaced across `recur`
leaks every superseded slab; the loop result leaks too) structurally,
by making every Str a loop binder holds OR a loop returns an owned heap
slab — then deleting the `!is_str` carve-out from BOTH codegen gates
that carried it. The leg-by-leg `!is_str` patches are gone.
Mechanism (the milestone thesis: representation in MIR, codegen reads
it). lower_to_mir sets rep = StrRep::Heap on every Str literal in a
loop-carried position; codegen's MTerm::Str arm promotes a Heap literal
via ailang_str_clone (a fresh ailang_rc_alloc slab, rc_header refcount
1). Three promotion positions, all in the Loop/Recur lowering:
1. binder seed inits (is_str_ty on the binder type);
2. recur args at Str-binder positions (read off the innermost
loop_stack frame);
3. exit-arm tail result literals (promote_tail_str_literals walks the
loop body's tail positions when the loop returns Str).
With every loop-carried Str now owned-heap, both gates lose !is_str:
the recur superseded-value dec (lib.rs) frees each intermediate slab;
the loop-result trackability gate (drop.rs:493) lets the caller's
scope-close free the final slab.
Why both gates, and the planning-time error this corrects. The original
plan/spec scoped the deletion to the recur dec gate only, reasoning the
#49 loop result is "consumed by print". The implement-orchestrator
landed that scope (Tasks 1-2) clean and correctly BLOCKED: it took #49
from live=3 to live=1, the residual being the loop RESULT. I verified
the diagnosis empirically:
- print BORROWS its arg (prelude: `(let s (show x) (do io/print_str
s))`, the eob.1 heap-Str discipline), so `(print s)` does not free
the loop result; the caller's let-binder does, via drop.rs:493.
"consumed by print" != "freed by print" — that was the error.
- Deleting drop.rs:493's !is_str takes #49 and the recur-literal
fixture to live=0.
- Deleting drop.rs:493 WITHOUT exit-arm promotion SIGSEGVs (exit 139)
on a loop returning a static Str literal — hence the third
promotion position and the static-exit witness.
The agent surfaced a real spec defect via an empirical BLOCK rather
than guessing; I corrected the spec refinement note (both gates, three
positions) and completed the loop-result leg inline, the context
already loaded from verifying the BLOCK (CLAUDE.md "already loaded
context" carve-out). drop.rs:493's Str carve-out is now sound to delete.
Boundary (asserted ill-typed, not constructible): a borrowed static-Str
Var seeded/recur'd into a consumed Str loop binder — rejected upstream
by uniqueness (a consumed binder position is owned).
Verification (orchestrator-run): all four leak fixtures reach live=0
under AILANG_RC_STATS — #49 (xyyy), recur-literal (reset), static-exit
(result), and the

feat(codegen): fill MArg.mode for App args, read the anon-temp drop gate off it, delete module_def_ail_types (mir.3b)
Second of two iterations delivering spec 0060's mir.3 row (plan docs/plans/0118-mir.3b-marg-mode-and-table-delete.md). lower_to_mir's Term::App arm fills each MArg.mode from the resolved callee's param_modes (the sig = synth_pure(callee) it already holds); codegen's emit_call anon-temp borrow-slot drop gate reads arg.mode instead of re-looking-up the callee's param_modes from the module_def_ail_types table; and — since that gate was the table's only reader — the module_def_ail_types field plus all its construction and threading are deleted. Two refinements to the spec's mir.3b sketch, settled in planning from a focused recon and recorded in spec 0060: 1. module_def_ail_types is deleted in mir.3b, not mir.5. A grep proved self.module_def_ail_types had exactly ONE reader (the anon-temp gate); the own-param drop reads param_modes from the def's own f.ty, not this table. Once the gate moves onto MArg.mode the table is dead, so it is removed now rather than carried as dead code to mir.5. The mir.5 row's "last re-derivation residue" shrinks to the element-type / Term::New (New.elem) work. 2. MArg.mode is filled for App args only; MTerm::Let.mode is not filled. Only App args have a real per-arg mode source (the callee Type::Fn.param_modes). Do args (EffectOpSig has no param modes), Ctor args (no per-field mode), and Recur args (loop binders carry no mode) stay Mode::Owned. Let.mode has no source (ast::Term::Let has no mode field) and no consumer (the let-drop gate reads consume, not Let.mode), so it stays Owned — filling it would invent a value nobody reads. Safety property held: MArg.mode is filled from the same callee fn-type the gate read from the table, so the drop fires identically. For (app RawBuf.get (app RawBuf.set …) 0), RawBuf.get's param 0 is borrow, so args[0].mode = Borrow — exactly the value module_def_ail_types yielded. Confirmed by the anon-temp witness staying green. ParamMode -> Mode conversion: Borrow -> Mode::Borrow; Own and Implicit (the Implicit ≡ Own contract) -> Mode::Owned. The own-param drop keeps reading ParamMode off f.ty (Type/ParamMode imports retained, live readers at lib.rs:1356/1507). Also retires three now-stale doc comments that named the deleted module_def_ail_types field (ailang-check/src/lib.rs, uniqueness.rs, and the codegen_import_map_fallback_pin test doc) — a direct consequence of the deletion, reworded to the current architecture. Verification (orchestrator, post-implement inspect): diff matches the plan (App-arg m_args built before m_callee consumes sig — the benign borrow-order deviation the plan's note flagged); module_def_ail_types grep-clean across all of crates/; cargo build --workspace clean (no unused/dead_code); cargo test --workspace 702 passed / 0 failed / 3 ignored (+1 = the new producer pin app_arg_carries_callee_borrow_mode; no #[ignore] added). The anon-temp drop-correctness witness raw_buf_owned_drop_balances_rc_stats stays live=0, now driven by MArg.mode; the other RC-stats leak pins green; #49 stays #[ignore] (mir.4); #51/#53 build guards green. mir.3 is now complete (3a relocated consume_count + deleted the second uniqueness run; 3b filled the mode annotation + deleted module_def_ail_types). Remaining: mir.4 (#49 StrRep RED->GREEN), mir.5 (element-type/Term::New + ledger). |

feat(codegen): relocate per-binder consume_count into MIR; delete codegen's second uniqueness run (mir.3a)
First of two iterations delivering spec 0060's mir.3 row (plan docs/plans/0117-mir.3a-consume-count-relocation.md). The per-binder consume_count — the only thing codegen read from its second infer_module_with_cross run — now lives on a new binder-keyed MirDef.consume: BTreeMap<String,u32>, filled once by lower_to_mir on the post-mono body. Codegen builds its existing (def,binder)->consume_count lookup from those maps and the three scope-close drop sites (own-param, let-binder, match-arm) read it; the codegen uniqueness run, its UniquenessTable field, and the import are deleted. mir.3 is split into two iterations (recorded in spec 0060): the named deletion depends ONLY on consume_count. All three drop sites read consume_count from self.uniqueness, while the modes they also gate on (param_modes for the own-param dec, scrutinee_is_owned for the match dec) come from the type, not the uniqueness pass (UniquenessInfo carries no mode). So mir.3a relocates consume_count and ships the deletion; mir.3b (next) fills MArg.mode/MTerm::Let.mode and switches emit_call's anon-temp gate onto MArg.mode. The split halves the change at the codebase's highest-risk surface (RC/drop correctness, the raw-buf leak saga) and makes each half independently verifiable against the live=0 leak pins. Design: consume_count lands on MirDef (binder-keyed), NOT on MArg. The drop sites key by (def, binder_name) — a per-binder aggregate — while the spec-sketched MArg.consume_count is per-arg-position and never reaches them; the per-def map matches the UniquenessTable's own keying and all three binder kinds (param/let/pattern) uniformly. MArg.consume_count stays a mir.1 default. Source = run check's infer_module_with_cross inside lower_to_mir post-mono (the synth_pure single-engine-re-walked pattern); retaining a check-time result is blocked (check's uniqueness is pre-mono and runs on-demand-from-codegen, never in check_workspace, so it would miss the mono specialisations). cross_module_types (= codegen's module_def_ail_types) is rebuilt in elaborate_workspace from the post-mono workspace. Safety property held: this is a PURE RELOCATION of an identical computation — infer_module_with_cross ran on the post-mono module in codegen and now runs on the same post-mono module in lower_to_mir, so drop placement is byte-identical. cross_module_types matches module_def_ail_types exactly (both insert f.name->f.ty over post-mono Def::Fn), confirmed by the leak pins staying green. Verification (orchestrator, post-implement inspect): diff matches the plan; codegen grep-clean for infer_module_with_cross + UniquenessTable (now ailang-check-internal); cargo build --workspace clean (no errors, no unused warnings — module_def_ail_types survives for emit_call's anon-temp param_modes gate); cargo test --workspace 701 passed / 0 failed / 3 ignored (+1 = the new producer pin mirdef_consume_is_populated_for_let_binder; no #[ignore] added). The live=0 drop-correctness witnesses all green: alloc_rc_loop_valued_rawbuf_binder_drops_at_scope_close (#43/#47), alloc_rc_heap_loop_binder_replaced_by_recur_does_not_leak, alloc_rc_print_int_does_not_leak_show_result_str. #49 stays #[ignore] (mir.4); #51/#53 build guards green. |

feat(codegen): pre-resolve the App callee in MIR; delete is_static_callee + type_home_module (mir.2)
Second re-deriver removal of the typed-MIR milestone (spec
docs/specs/0060-typed-mir.md, plan docs/plans/0116-mir.2-callee-static.md).
Static-callee resolution moves out of codegen and into lower_to_mir:
every Term::App callee is classified once, mirroring check's own synth
Term::Var ladder (lib.rs:3409-3582), and emitted as a resolved Callee.
Codegen reads the callee identity off MIR and routes each kind to the
right lowering. The codegen re-derivers is_static_callee and
type_home_module are deleted, and the lower_app <-> is_static_callee
lockstep pair is struck from CLAUDE.md.
Callee reshape (beyond the spec's original {module, fn_name} sketch —
spec 0060's Concrete-code-shapes block is updated in this iteration):
pub enum Callee {
Static { module, fn_name, sig: Type }, // user/prelude fn -> emit_call, module pre-resolved
Builtin { name, sig: Type }, // operator/intrinsic -> inline opcode lowering
Indirect(Box<MTerm>), // dynamic: fn-pointer / closure / shadowed name
}
Two forced refinements, both settled in planning:
- sig:Type on each resolved variant. drop::synth_callee_ret_mode reads
the callee ret_mode, today off Callee::Indirect(inner).ty(). A
resolved callee has no sub-term, so the sig (= synth_pure(callee),
mode-preserving) is the lossless replacement. This is NOT a mir.3
pull-forward: the MArg param-mode / consume_count fields stay at their
mir.1 defaults. Without it, every statically-resolved call would lose
its drop signal and the RawBuf / int_to_str RC-stats pins mir.1b fixed
would regress.
- Builtin variant. Operators and the str-num builtins (+, not,
str_concat, ...) are lowered inline by name and have no module/fn_name;
a separate variant is cleaner than a sentinel module. The classifier
decides Builtin vs Static from CHECK'S OWN resolution (a name in
env.globals with no owning module is a builtin), never a copy of
codegen's old is_static_callee allowlist. The recon's divergence audit
confirmed check's builtin set and codegen's inline-arm set match
exactly, so the single-engine rule is mechanically satisfiable with no
env threading gap.
type_home_module is fully deletable: a workspace-wide grep confirmed no
program references a type-scoped T.fn as a value, so its only other
consumer (resolve_top_level_fn) collapses to the module-name fallback
with no behaviour change. (The spec's "x3 mirrors" wording over-counted;
the live surface was the definition plus two call sites.)
Alternatives rejected during planning: sentinel module in Static
(ugly); builtins left as Indirect (breaks — no fn-pointer for an
operator); name-rewrite Static{name,sig} keeping lower_app's by-name
dispatch (blurs builtin/user and still needs sig). The mir.1b
re-synth-strictness trap (post-mono synth_pure re-unify surfacing
mode-strip / bare-vs-qualified / metavar leaks) did NOT fire under the
new producer path — qualify_local_types mode-preservation and the $u
wildcard normalisation from mir.1b held.
Verification (orchestrator, post-implement inspect): diff matches the
plan; grep-clean for is_static_callee + type_home_module across
ailang-codegen and ail; cargo build --workspace green; cargo test
--workspace 700 passed / 0 failed / 3 ignored (no #[ignore] added this
iteration — the 3 are the pre-existing #49 Str-leg pin + two doctests).
Acceptance witnesses green: #53 (mono_new_over_user_adt_builds_and_runs),
#51 (rawbuf_new_int_size_only_builds_and_runs still builds), show_print
cross-module (print_user_adt_runs_end_to_end), the new mir.2 pins
(mir2_resolved_callee_kinds_run_end_to_end, callee_classification_*,
strengthened new_over_user_adt_carries_node_types asserting Callee::Static).
#49 heap-Str loop binder stays #[ignore] (lifts at mir.4).
Two new examples/ fixtures back the new pins (classify_pin.ail for the
producer classification pin, mir2_callee_kinds.ail for the E2E),
ail-parse / round-trip clean.
Forward note (cycle-close architect): crates/ail/tests/codegen_import_map_fallback_pin.rs:14-15
doc prose names lower_app's cross-module arm and synth_with_extras as
failure-mode targets — both now deleted (mir.2 / mir.1b). The pin's
protected invariant is still valid and green; the prose is stale and
wants a doc-honesty reword, left out of this iteration's footprint.

fix(check): preserve fn-type modes through Subst::apply
`Subst::apply` rebuilt every `Type::Fn` with `param_modes: vec![]` and `ret_mode: Implicit`, discarding the modes the surrounding type carried. That was harmless while nothing downstream of inference read fn-type modes — but it is a latent under-specification: substitution is meant to be type-preserving, and a fn type's modes are part of its identity (an `(own T) -> (own U)` contract is not the same contract as its borrow-returning sibling). Modes are positional over `params`, and substitution remaps each param type element-wise without changing the arity, so the mode lists stay aligned — preserving them is a clone, not a re-derivation. The typed-MIR boundary (milestone 0060) makes this load-bearing: a node type synthesised by `lower_to_mir::synth_pure` ends with `subst.apply`, and the codegen drop path reads `ret_mode == Own` off a call's callee node to decide RC trackability. With the modes stripped here, an Own-returning call read back `Implicit`, nothing was trackable, and a heap-allocated binder leaked at scope close. Preserving the modes restores that signal at the source rather than re-deriving it in codegen (which is exactly the re-derivation the milestone exists to delete). Safe by construction: `unify`'s Fn arm destructures modes with `..` and compares only params/ret/effects, so carrying modes through `apply` cannot change unification; and `Type`'s custom `PartialEq` already treats `Implicit` and `Own` as interchangeable (only `Borrow` is distinct), so equality outcomes are unaffected except where preserving a `Borrow` is the more correct answer anyway. Whole `ailang-check` suite stays green. RED pin: crates/ailang-check/tests/subst_preserves_modes.rs. |

fix(check): localize own-ADT type-args in free-fn mono; complete the lower_to_mir producer
Additive producer-side work for the typed-MIR milestone (spec
docs/specs/0060-typed-mir.md), surfaced while building the mir.1b
codegen-consumption switch. Nothing here consumes MIR — codegen is
untouched; the whole existing suite stays green and one new RED pin
goes green. The mir.1b codegen switch itself stays in the working tree.
Headline fix — own-ADT type-arg localization in free-fn mono:
monomorphise_workspace's free-fn arm normalises every observed
type-arg through Registry::normalize_type_for_lookup. That
normalisation is load-bearing for cross-module dedup and a stable
specialisation symbol name, but it qualifies a *defining-module-own*
ADT to `<module>.<T>`. synthesise_mono_fn_for_free_fn then substitutes
those qualified type-args into the polymorphic source signature and
body, which are in the module's own *bare* convention (the qualify
pre-pass deliberately leaves own-module type-cons bare — lib.rs:4358,
"the current module sees its own types bare"). The result is a
self-inconsistent specialisation: e.g. fold_left specialised with
accumulator b := List<Int> minted
((std_list.List<Int>, Int) -> std_list.List<Int>,
std_list.List<Int>, List<Int>) -> std_list.List<Int>
— a qualified accumulator parameter against a bare list argument and a
bare Lam body. check_workspace never hits this (it synths the pre-mono
bodies, bare throughout); the old codegen tolerated it via the
now-deleted synth_arg_type's loose type-tracking. The post-mono synth
re-entry in lower_to_mir does full unification and correctly rejects
it: `expected std_list.List<Int>, got List<Int>`.
Fix: localize_own_types (mono.rs) strips the `<defining_module>.`
prefix back to bare for the module's own ADTs, applied to the type-args
before they are substituted, so the synthesised signature and body stay
uniformly bare-own. The *stored* type_args remain normalised, so the
symbol name and the Phase-3 rewrite-cursor key on the same canonical
form — the byte-identity invariant between synthesis and rewrite is
untouched. The ClassMethod arm needs no analogue: it already
substitutes the un-normalised target.type_ (mono.rs:841).
Alternatives rejected: (a) drop the normalisation in the shared
apply_subst_and_normalize helper — breaks cross-module dedup, mints
duplicate specialisations under divergent names. (b) Make
lower_to_mir's synth treat `<owner>.T` and bare `T` as equal during
unification — papers over the producer inconsistency in the consumer
and contradicts the established own-types-stay-bare invariant the rest
of check relies on. (c) Qualify the whole synthesised def own->qualified
— fights lib.rs:4358 and would require the lower path to also flip,
cascading the convention change through synth.
Producer completeness (additive, mirrors existing guards):
- lower_module skips Type::Forall defs (lower_to_mir.rs), mirroring
emit_module's guard. Polymorphic defs are stale source kept for
round-trip; their bodies carry mono-rewritten call names for
specialisations that were never synthesised, so a synth re-entry
would hit UnknownIdentifier.
- lower_module lowers non-literal const bodies to typed MTerm, carried
in MirModule.consts (+ MirConst in ailang-mir). A non-literal const
(e.g. a List ctor expression) needs a typed body once the consumer
walk takes &MTerm; literal consts emit a global and need no body.
- MirModule gains `ast: Module`, populated by lower_module — forward
scaffolding the mir.1b codegen consumption reads for module
structure. Populated here, consumed by the in-tree switch.
Verification: full `cargo test --workspace` green (697 passed, 0 failed)
with the codegen-consumption switch stashed out, including the new pin
crates/ailang-check/tests/lower_to_mir_ty.rs::poly_free_fn_accumulating_into_own_adt_elaborates
(RED before the localize fix with the exact mismatch above, GREEN after)
and the full e2e corpus (the own-ADT-poly demos elaborate clean and run
through the old codegen). This proves the producer fix is
regression-free and the remaining 22 e2e reds in the working tree are
codegen-consumption defects, not producer defects.

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 |

fix(check): qualify cross-module kernel type-cons in user ADT fields
A consumer module's ADT field could reference a kernel-tier auto-imported type by its bare name in op/value positions (`(new RawBuf ...)`, `RawBuf.get`) but NOT in the type-constructor position of the field declaration: `(con RawBuf (con Int))` stayed the unqualified `RawBuf<Int>` and failed to unify with the constructor argument's `raw_buf.RawBuf<Int>`, so a RawBuf could not be stored in a user ADT field without spelling the qualified `raw_buf.RawBuf`. `qualify_workspace_module` skipped `Def::Type` entirely, and the `Term::Ctor` arm only qualified field types of cross-module *owning* types — a *local* type carrying a cross-module field was the uncovered case. The fix qualifies each ctor field type in the `Def::Type` arm via the existing `qualify_workspace_types`, which upgrades only genuinely cross-module type-cons (skips `own_local_types` and primitives), so a purely-local field is never spuriously rewritten. This is a check-side workspace transform, not the on-disk canonical form, so no module hash drifts (both hash-pin tests stay green). RED test `rawbuf_in_user_adt_field_resolves_bare_name` in crates/ailang-check/tests/workspace.rs, with the bare-name fixture (now checks/builds/runs -> 42, live=0, the ADT drop cascade frees the buffer slab) and the qualified control twin. This is the Series-substrate shape (a RawBuf wrapped in a user ADT), so the inconsistency would have bitten the pending series milestone. closes #50 |

fix(check): resolve type-scoped borrow-receiver ops in linearity (closes #46)
A function whose parameter is `borrow (RawBuf a)` and which calls RawBuf.get or RawBuf.size on that parameter even once was rejected at `ail check` with [consume-while-borrowed] — the exact borrow-receiver use the ledger advertises for get/size. The diagnostic also misnamed the cause: the receiver is read, not consumed. Root cause: the linearity walk's callee_arg_modes looked up the callee under its spelled name. A type-scoped polymorphic op is spelled `RawBuf.get` at the call site, but check_module_with_visible registers the kernel raw_buf ops under their bare def names (get/size). The lookup missed, the receiver arg defaulted to Consume, and consuming a binder whose borrow_count==1 (the Borrow param) fired the false positive. The kernel signatures themselves are correct (receiver slot is `borrow`); the only defect was the name-resolution gap in the linearity globals lookup. Fix: on a direct-lookup miss, fall back to the bare method name via the existing parse_method_qualifier + qualifier_is_class_shape resolvers, gated on a class/type-shaped qualifier so lowercase cross-module-fn qualifiers (std_list.length) are excluded. This is how the rest of the checker already treats type-scoped polymorphic ops; the fix is general, not RawBuf-specific. This unblocks the natural borrow-helper decomposition (a shared read-only buffer behind a helper fn) — the shape the downstream series milestone's Series.at / Series.total_count need. Surfaced by the raw-buf fieldtest (finding B1, docs/specs/0058). RED-first: rawbuf_borrow_receiver_read_is_linearity_clean. |

GREEN: pre-pass/resolver asymmetry — same-module bare + kernel-tier qualifier acceptance (closes F1, F3)
Two minimal edits in ailang-check that bring the resolver's acceptance set into line with what prep.1's workspace pre-pass (`prepare_workspace_for_check`) actually produces. The pre-pass itself is unchanged — its qualification rules are correct per spec § "Realisation mechanism — workspace pre-pass". RED tests landed in 4d39fdc; both turn GREEN, both fieldtest fixtures that surfaced the bugs now `ail check` clean. F1 — same-module type-scoped call (kem_2b_min_repro.ail). The dot-qualified `Term::Var` arm in `synth_term` (`crates/ailang-check/src/lib.rs` ~line 3425) was unconditionally rewriting the resolved fn signature via `qualify_local_types`, so a call like `(app Counter.value c)` from inside Counter's home module produced a return type `<this>.Counter` — but the matching `Term::Ctor` arm (~line 3644) and the pre-pass itself both leave own-module type-names bare. The two halves of the resolver disagreed. Fix: branch on `target_module == env.current_module` — when true, skip the qualification (the raw type is already in the form the rest of the resolver speaks); when false, qualify as before. `owner_types` lookup moved inside the else-branch since it's only consulted when qualification runs. A short comment names the pre-pass and the sibling Term::Ctor arm so a future reader sees the three-way symmetry. F3 — kernel-tier qualifier acceptance (kem_3_stub_consumer.ail). The env-builder paths `build_check_env` (~line 1653) and `check_in_workspace` (~line 1807) force-injected only `"prelude"` into `env.imports` / `env.module_imports`. The loader meanwhile derives the implicit-imports list from `modules.values().filter(|m| m.kernel)` (since prep.3) — so `kernel_stub` flows into runtime resolution but not into the checker's qualifier-validity check (~line 1968). Bare `StubT` got qualified by the pre-pass to `kernel_stub.StubT`, then bounced off the validity check as "unknown module prefix". Fix at both sites: keep the unconditional `"prelude"` literal injection AND additively insert every workspace module with `kernel: true` into the per-module import map (skip self-injection). Idempotent for production (where prelude also carries `kernel: true`) and preserves the `bare_name_resolves_through_implicit_import_to_free_fn` unit-test contract — that test deliberately constructs a prelude module with `kernel: false` to pin the legacy "prelude is always implicit" guarantee per se, independent of the kernel flag. Mirrors the loader's kernel-flag filter, making the env-builder and the loader speak the same set. Sibling pin `crates/ailang-check/tests/env_construction_pin.rs` (the frozen-reproduction copy of `build_check_env`'s `module_imports` loop) updated in lockstep so it remains a meaningful drift detector after the env-builder change. The pin is intentionally designed to track legitimate behavioural changes. Verification: - tests::type_scoped_call_in_same_module_resolves GREEN - tests::kernel_tier_module_qualifier_resolves_… GREEN - examples/fieldtest/kem_2b_min_repro.ail ail check ok - examples/fieldtest/kem_3_stub_consumer.ail ail check ok - cargo test --workspace 666 / 0 (664 prior baseline + 2 RED→GREEN this iter) Implementer notes: one re-loop on the F3 site after the first edit replaced the legacy "prelude" literal injection wholesale with the kernel-flag filter — that broke the unit-test contract above. Restored the literal AND added the filter on top per the "don't adapt tests to bugs" memory. No spec-review or quality-review loops. prep.1's pre-pass design (spec § "Realisation mechanism") was correct as written — the symmetry between owner-side `qualify_local_types` and consumer-side `prepare_workspace_for_check` holds. What was missing was uniform resolver-side acceptance of the qualifiers the pre-pass produces. With these two edits, the following equivalences hold throughout the checker: bare T ≡ <this-module>.T (F1, same-module rule) bare T ≡ <kernel-module>.T (F3, kernel-tier rule) via the loader-driven implicit-imports list that now drives both the checker's import map and the type-validity check. |

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

iter prep.1-type-scoped-namespacing (DONE 5/5): TypeDef-first resolution + workspace pre-pass — closes #31
First iteration of the kernel-extension-mechanics milestone. Ships
the type-scoped `<TypeName>.<member>` resolution path as the
canonical form for type-associated operations, narrows the
`BareCrossModuleTypeRef` / `BadCrossModuleTypeRef` diagnostics from
"bare = strictly local" to "bare = in-scope by any path", migrates
12 std-library example fixtures, and introduces a workspace-wide
normalisation pre-pass `prepare_workspace_for_check` shared between
`check_workspace` and `monomorphise_workspace`.
Architectural discovery during implementation: the plan covered the
`Term::Var` dot-qualified resolver layer plus the workspace
validator's bare-name acceptance, but the migration of bare-form
fixtures exposed five sites where bare vs. qualified type-names
needed symmetric treatment — `Term::Ctor` resolution, `Type::Con`
well-formedness, mono's poly-free-fn name/constraint-count
enumeration, codegen's `lookup_ctor_by_type` bare-name path, and
the upstream desugar-then-qualify composition. Rather than
scattering TypeDef-first ladders across each site, the implementer
centralised the work into one pre-pass that walks every consumer
module's `Type::Con.name` and `Term::Ctor.type_name`, rewriting
bare cross-module references to their qualified `<home>.<Type>`
form. This is symmetric to the pre-existing `qualify_local_types`
(owner-side); the new pre-pass is the consumer-side mirror.
Downstream passes see qualified Types regardless of authoring form.
The TypeDef-first ladder still lives in `synth`'s `Term::Var` arm
because `<TypeName>.<member>` is term-position-only — `Maybe.from_maybe`
is a Var, not a Type expression, and the pre-pass does not rewrite
Var names.
Alternatives considered:
(a) Add TypeDef-first ladder at every resolution site separately
(the plan's implicit assumption). Rejected: O(N) extension
sites, each carrying the same workspace-walking logic; the
pre-pass version is O(1) — one pass, every downstream consumer
benefits.
(b) BLOCKED + spec re-brainstorm. Rejected: the architecture
extension is consistent with prep.1's thesis (bare type-name
resolves to the workspace-wide TypeDef) and forward-compatible
with prep.2 (Term::New.type_name falls under the same rewrite)
and prep.3 (kernel-tier TypeDefs enter the workspace map
automatically). No design regression to bounce back over.
Spec updated to document the realisation mechanism honestly: the
"Realisation mechanism — workspace pre-pass" subsection clarifies
that the resolver-level semantics described in "Implementation
shape" are the user-facing contract, and the actual code path is
the pre-pass.
Verification:
- `cargo test --workspace`: ALL GREEN. 87 e2e + every crate's unit
+ integration tests pass with no regressions.
- Three NEW in-source tests pin Task 1's resolver paths:
`type_scoped_member_resolves`, `type_scoped_member_not_found`,
`type_scoped_receiver_not_a_type`.
- One NEW workspace test pins the narrowed validator:
`ct1_validator_accepts_bare_with_explicit_import`.
- One renamed-and-flipped existing test:
`ct1_validator_rejects_bare_xmod_with_import_candidate` →
`ct1_validator_accepts_bare_xmod_with_import_candidate` (the
bare-with-import path is now ACCEPTED).
- One NEW companion test for the workspace-wide ctor lookup:
`ct2_term_ctor_bare_cross_module_via_workspace_resolves`.
- Two pre-existing tests' assertions updated for the new error
wording: `ct1_check_cli::check_human_mode_emits_actionable_message_to_stderr`
and `crates/ailang-check/tests/workspace.rs::unknown_module_prefix_is_reported`.
- 12 migrated `.ail` fixtures verified via the existing e2e
suite (each fixture is the test runner's target for an existing
`build_and_run` assertion).
- Negative fixture `ct_2_bare_cross_module.ail` semantically
preserved: dropped its `(import std_maybe)` so bare `Maybe` is
out-of-scope under the narrowed rule and still fires
`BareCrossModuleTypeRef`.
Concerns:
- The pre-pass introduces a new architectural layer (consumer-side
qualification) that the spec did not originally anticipate. Spec
amendment in this commit documents the layer. Future iterations
reference `prepare_workspace_for_check` as established
infrastructure.
- `examples/test_ct1_bare_xmod_rejected.ail.json` switched its
offending name from bare `Ordering` (which under the prep.1
semantics may now resolve via implicit prelude) to a still-
unresolvable `Mystery_Type`. The CLI test's intent (assert that
a human-mode `ail check` exits non-zero on a still-RED case) is
preserved.
Milestone status: kernel-extension-mechanics (Gitea #6) advances
1/3 iters. Next: prep.2 (`Term::New` construct) issue #32.

workflow: delete docs/journals/ and docs/journal-archive.md
Strict application of the "Future-Use, not Verlauf" criterion to the
two remaining journal artefacts:
- `docs/journals/` (110 files): the per-iter and audit journals from
2026-05-11 onward. Pure history; no live reader after the previous
sweep. Entire directory removed.
- `docs/journals/2026-05-19-design-decision-records.md`: the one file
that had live readers (`docs_honesty_pin.rs:108`, `parse.rs:80`,
`duplicate_ctor_pin.rs:8`, three roadmap.md mentions) and was framed
as a "relitigation guard". On re-examination its three asserted
pinned phrases ("Regions were considered and rejected", the
"demands annotations *because*" rationale, the prose-render
placeholder statement) are rationale-prose, not load-bearing
invariants — the test pinned itself, not a system property. Any
Decision that still holds lives in the code, `design/contracts/`,
or `design/models/`. Removed with the rest.
- `docs/journal-archive.md` (pre-2026-05-11 history): content-frozen
long-tail history with no live reader. Removed; if anyone ever
needs the pre-cutoff rationale they can `git log --before=2026-05-11
--grep=<keyword>`.
Live-file consequences:
- `docs_honesty_pin.rs` `design_md_present_tense_anchors_present`:
the three `records.*` assertions and the `read("docs/journals/…")`
are dropped; the contract/model anchor pins remain.
- `duplicate_ctor_pin.rs`: the "why-two-overlays rationale lives in
docs/journals/…" comment is replaced with the rationale inline.
- `parse.rs`: the "form-refinement rationale lives in docs/journals/…"
comment is dropped (the rule body already states the refinement).
- `roadmap.md`: the decision-records mention in the DESIGN.md →
design/ entry's body is dropped; the journal-archive.md `context:`
pointers across ~12 closed entries are either rephrased to point
at the relevant iter/audit (no path), or simplified to a one-line
comment when the iter name alone carries the story.
- `CLAUDE.md` Roles section: the `docs/journal-archive.md` slot is
removed; vocabulary note rephrased.
- `design/INDEX.md`: the Docs bullet drops `journal-archive.md`.
- `skills/README.md` bootstrap-rationale pointer rephrased.
`docs/specs/` and `docs/plans/` (per-milestone specs and per-iteration
plans) are unaffected — they remain the structured-design artefacts
they were before this sweep.
Workspace builds, full test suite green.

workflow: replace per-iter journal system with git log + BLOCKED.md
The per-iter journal under docs/journals/ duplicated the iter commit body's substance and accumulated as Verlauf-Doku with no Future-Use. Sweep across all live control documents: CLAUDE.md, the 7 SKILL.md files, the 11 agent files, design/INDEX.md and the contracts/models that referenced journals, docs/roadmap.md, and the handful of source comments + tests that pointed at journal files for rationale. Mechanism changes: - Standing-reading-lists in every agent now read `git log -N --format=full` for recent project state, never per-iter journal files. The architect reads `git log <prev-milestone-close>..HEAD --format=full` for audit scope. - implement-orchestrator no longer writes a journal file. DONE outcomes emit just code + stats; the end-report is the per-task summary the Boss uses to write the commit body. PARTIAL/BLOCKED outcomes emit BLOCKED.md at the repo root — uncommitted by convention, Boss removes on repair or discard. New iron-law line + four-rationalisation row + red-flag bullet codify it. - audit ratify mechanic: --update-baseline is now paired with an explicit ratify paragraph in the audit-close commit body, not a separate JOURNAL ratify entry. - design/contracts/honesty-rule.md: "history and rationale lives in docs/journals/" → "lives in git log (iter and audit commit bodies)". Pinned phrase preserved verbatim. - CLAUDE.md "Roles of …" section reframed: design/, git log, journal-archive.md (content-frozen), roadmap.md, specs/, plans/. No docs/journals/ slot anymore. - roadmap.md context-lines that pointed at per-iter journals are dropped where the spec/commit already carries the rationale, or rephrased to "shipped in the <iter> iter commit" / "docs/journal- archive.md (<date> entry)" for pre-2026-05-11 references. What stays (this commit): - docs/journals/ directory and contents are NOT touched. Removing the contents is a separate follow-up. - docs/journals/2026-05-19-design-decision-records.md still has live readers (docs_honesty_pin.rs Z 108 + parse.rs + duplicate_ctor_pin.rs + 3 roadmap mentions) — also follow-up. - docs/journal-archive.md still exists; its self-pointer header has been updated to drop the "see docs/journals/INDEX.md" mention. Workspace builds, full test suite green. |

design/ + source rustdoc: replace opaque shorthand with content phrases + links
Reader-facing prose and rustdoc carried opaque shorthand like
"Decision 10", "clause-5", "mq.1", "ct.1", "eob.1", "rpe.1",
"post-mq.3", and "Iter 22b.1:" with no in-repo definition the reader
could follow. This commit replaces every such occurrence in the
durable tier the reader is most likely to land on (design/ ledger +
source //! module headers + the central /// public-item rustdoc) with
an inline content phrase plus, where applicable, a Markdown link to
the file that defines the referenced concept.
design/ ledger — 16 files:
Definition-site headings demoted from "Decision N: <title>" to
"<title>": authoring-surface, tail-calls, memory-model section in
rc-uniqueness.md, dual-allocator section, typeclass design,
effects "pure core + algebraic effects".
Cross-reference sites: "Decision 1" -> canonical-schema principle
(data-model); "Decision 3/4" -> effects + scope-boundaries; "Decision
6" -> authoring-surface; "Decision 8" -> tail-calls; "Decision 9" ->
rc-uniqueness (dual-allocator); "Decision 10" -> memory-model;
"Decision 11" -> typeclasses (model). "clause-5" -> body-link
durability gate. "clause-3" (in language-constraints) ->
bug-class-reintroduction discriminator. "mq.1/2/3", "ct.1/4",
"eob.1", "rpe.1" -> the canonical-form rule / the type-driven
dispatch / the Str carve-out / etc. "post-mq.3" -> "type-driven".
design/contracts/feature-acceptance.md: file-local "clauses 1/2/3"
-> "criteria 1/2/3" (sprachliche Kohärenz mit der File-Überschrift
"Feature-acceptance criterion"); "the clause-3 mechanism" -> "the
bug-class-reintroduction discriminator".
Source //! module headers — 24 files:
Stripped "Iter X.Y:" prefixes and "(Decision N)" / "(mq.X)" tags
from spec_drift, uniqueness, reuse_shape, migrate_canonical_types,
typeclass_22b{2,3,c}, suppress_filter, lift, mono, linearity,

print_no_leak_pin, cli_diag_human_workspace_load_error,
ct1_check_cli, prose snapshot, unbound_in_instance_method_pin,
mono_xmod_ctor_pattern, desugar.
Central /// public-item rustdoc:
ast.rs (full sweep — every "Iter X" + "Decision N" prefix
reformulated; mode/Type::Fn rustdoc now points at memory-model.md;
Constraint / SuperclassRef / InstanceDef / ClassDef rustdoc points
at typeclasses contract).
diagnostic.rs (all "(Iter X)" / "(mq.X)" tags on diagnostic codes
removed).
lib.rs (FORM_A_SPEC rustdoc points at authoring-surface.md
instead of "Decision 6").
canonical.rs (type_hash + Float-literal rustdoc).
Still outstanding (for a follow-up commit): ~500 inline `//`
code-body comments with `Iter X.Y` markers across the workspace, and
a handful of `///` rustdoc items in hash_pin / workspace_pin / lift /
mono / suppress_filter test-pin and internal-function bodies. Code
identifiers (test filenames like `mq3_multi_class_e2e.rs`, function
names like `iter18e_drop_iterative_default_preserves_hashes`) stay
verbatim per the user's "code identifiers stay verbatim" rule.
Tests: design_index_pin 5/5 + docs_honesty_pin 5/5; workspace builds
clean; full `cargo test --workspace` previously green (every
`test result: ok` line, no FAILED line).

Boss spec-consistency repair (M2.1-precedent class): orchestrator correctly BLOCKED Task 5 on a genuine spec defect -- the single-ctx-readback allocs==frees proof model is unsatisfiable for borrow (and only coincidentally passes for own) because M2's TLS-ctx is bound only during the synchronous forwarder call, so host-side decs land on g_rc_*, not ctx. Boss-verified globally leak-free + value-correct both modes. Spec + plan + harness amended to the stronger global model (sum all ailang_rc_stats: lines; the M2-TLS cross-attribution documented as correct behaviour).

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.

iter mut.4-tidy + audit close — mut-local milestone closed
Tidy iter addressing the audit-mut-local drift. Plus paired baseline
update on bench/baseline_compile.json (audit-skill discipline).
Architect [high] items closed:
1. CheckError::MutVarCapturedByLambda rejects lambdas whose body
free vars include a mut-var of the enclosing mut_scope_stack.
Uses the existing ailang_core::desugar::free_vars_in_term walker
(which honours Term::Match pattern bindings). The scan runs only
when mut_scope_stack is non-empty.
2. crates/ailang-codegen/src/lambda.rs: the capture-not-in-locals
path that previously raised CodegenError::Internal blaming the
typechecker now uses unreachable!. The companion comment block
was rewritten to state the current reality.
Architect [medium] items closed (stale mut.1-stub history comments):
3. docs/DESIGN.md §'Term (expression)' mut/assign block: the
trailing paragraph describing the iter mut.1 stub state was
replaced with one describing the current mut.3-end-state. The
inline jsonc comment on {'t': 'assign'} was updated to drop the
'deferred to mut.2/mut.3' language.
4. crates/ailang-codegen/src/lib.rs: the stale comment block above
the real Term::Mut arm describing the mut.1 stub was removed
entirely.
Other:
- Short-circuit on empty mut_scope_stack in synth's Term::Var arm:
the iter mut.2 prepend now skips the iter-and-find walk when
the stack is empty, eliminating any per-Var-resolution overhead
for the common case (programs with no mut blocks). The
short-circuit did NOT close the check_ms regression — see ratify
below.
- Spec docs/specs/2026-05-15-mut-local.md §'Out of scope' amended
with the lambda-capture rejection bullet.
- Negative fixture examples/test_mut_var_captured_by_lambda.ail.json
+ driver test extension in crates/ailang-check/tests/
mut_typecheck_pin.rs (6th test) +
crates/ailang-core/tests/carve_out_inventory.rs EXPECTED bumped
12 → 13.
Bench-regression ratify:
bench/compile_check.py check_ms showed a uniform ~30-50% relative
shift across the entire 11-fixture suite (~0.5ms absolute on a
1.4-1.5ms baseline). The uniformity across fixtures of very
different Var counts argues for a fixed-cost-per-invocation tax,
not a Var-proportional hot path. The Term::Var short-circuit
falsified the hot-path hypothesis. The plausible remaining causes
(synth-parameter-passing through ~19 recursive sites, and binary-
size startup tax from mut-* adding ~1400 LOC to typecheck/codegen)
are both feature-cost, not pathological. Ratified by paired
journal entry; bench/baseline_compile.json updated to the post-
mut-local numbers via 'bench/compile_check.py --update-baseline'.
bench/check.py continues to show the established tail-latency-noise
envelope from audit-pd (2026-05-14) — no separate ratify needed.
bench/cross_lang.py clean.
Tests: 594 → 598 green (4 new lib.rs mod tests + 1 driver test +
1 fixture-corpus uptake).

iter mut.2: typecheck for Term::Mut + Term::Assign
Replaces the iter mut.1 dispatch stubs in synth with real typecheck
logic. Codegen stubs stay (deferred to mut.3); examples/mut.ail now
typechecks clean but still cannot run end-to-end.
Concretely:
- crates/ailang-check/src/lib.rs: three new CheckError variants
(MutAssignOutOfScope, AssignTypeMismatch, UnsupportedMutVarType)
with #[error('[code]: msg')] Display attrs matching the cli-diag-
human bracketed-code convention; code() + ctx() arms emit
kebab-case codes and structured JSON payloads.
- synth signature: new parameter mut_scope_stack: &mut Vec<IndexMap<
String, Type>> after locals, threaded through every recursive call
site (synth's 18 internal calls + mono.rs:712/1337 re-synth +
lift.rs:723 + builtins.rs test helpers + the mq.3 in-test helper
at lib.rs:6663). Stack is per-walk and lexically scoped — push on
Term::Mut entry, pop on exit. Each frame is an IndexMap so
declaration order is preserved for the diagnostic 'available' list.
- Term::Var resolution: prepended with innermost-first mut-scope
lookup. Mut-vars are monomorphic — no Forall instantiation, no
free_fn_owner recording. Innermost-wins shadowing falls out of
the iteration order.
- Term::Mut arm: gate var types to Int/Float/Bool/Unit only via
a small is_supported_mut_var_type helper; each var's init is
synth'd in the in-progress scope (the var itself is not yet
bound, so it does not self-shadow during init); push completed
frame, synth body, pop. Block's type is body's type.
- Term::Assign arm: walk mut_scope_stack innermost-first looking for
name. On miss: MutAssignOutOfScope with available flattened
across all frames (innermost-first, deduplicated, preserving
order). On hit: synth value, unify against declared type — on
mismatch emit AssignTypeMismatch with rendered types; on success
produce Type::unit().
- Five .ail.json fixtures under examples/ exercising each
diagnostic plus a positive nested-shadow sanity case, driven by
the new pin test crates/ailang-check/tests/mut_typecheck_pin.rs
(load_workspace + check_workspace + assert exact codes).
- carve_out_inventory.rs EXPECTED extended 7 → 12 to cover the new
negative-fixture set (consistent with the form-a-default-authoring
spec §C4(b) precedent for type-rejection fixtures staying as
.ail.json-only).
Plan deviations from recon: three additional synth() call sites
beyond the four enumerated (lift.rs:723, builtins.rs x2,
lib.rs:6663) surfaced via the build-red structural signal; each
threaded with a fresh empty stack. carve_out_inventory.rs extension
was required by the existing pin but not named in the recon — a
documentary concern for the next planner pass.
Tests: 579 → 592 green; examples/mut.ail typechecks clean
('ok (26 symbols across 2 modules)') via cargo run --bin ail --
check examples/mut.ail; cargo build green; full workspace test
green.

iter rpe.1: retire per-type print effect-ops
Single iter shipping the post-milestone-24 follow-up named in
docs/specs/2026-05-14-retire-per-type-print-effects.md. After this
iter the only surviving direct-output effect-op is `io/print_str`;
all per-type print primitives are replaced by the polymorphic
`print` helper (prelude, iter 24.3).
Components:
- 92 examples/*.ail fixtures migrated (do io/print_<T> x) →
(app print x); 6 .prose.txt snapshots regenerated via `ail prose`.
- Four-site lockstep compiler deletion: crates/ailang-check/src/builtins.rs
(3 effect_ops.insert blocks + 3 list() rows + the
install_io_print_float_signature test + module + EffectOpSig
doc-comments); crates/ailang-codegen/src/lib.rs lower_app
(3 arms + lowers_io_print_float test); crates/ailang-codegen/src/synth.rs
builtin_effect_op_ret match-arm pattern. Dead `intern_string`
helper removed as a follow-up.
- Five incidental test-body migrations (ailang-check x2, ailang-core
spec_drift + design_schema_drift, ailang-surface/src/lex.rs,
ailang-prose/src/lib.rs round-trip test).
- Cat B test-harness patch: six IR-shape tests in
crates/ail/tests/e2e.rs gained a monomorphise_workspace call
before lower_workspace_with_alloc so they follow the same
pipeline as `ail build` (the home-rolled desugar+lift loop
stayed because mono's precondition is "already lifted"; mono
inserts after lift).
- Six doc-comment touch-ups (lex.rs module doc, parse.rs
diagnostic example, ail/src/main.rs x2, runtime/str.c %g anchor,
crates/ailang-core/specs/form_a.md surface-spec example).
- DESIGN.md seven-site sweep (Decision 11 example, Polymorphic
print past-tense, Heap-Str output sentence, effect-op
invocation comment, Float NaN paragraph re-anchored on
float_to_str, two "What is supported" lists).
- Three E2E test-comment polish + four IR-snapshot refresh + one
canonical-hash pin update (plan-unanticipated downstream
consequences of the corpus migration).
- bench/{check,compile_check,cross_lang}.py: all exit 0; no
ratification needed.
- Roadmap entry struck through; per-iter journal at
docs/journals/2026-05-14-iter-rpe.1.md.
Tests 564/0/3. cargo clippy and cargo doc: zero warnings.
Two upstream codegen bugs surfaced during the first BLOCKED
attempt and were fixed in separate iters before this retry:

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 24.2: class Show + 4 primitive instances + 22b TShow migration
Ships class Show a where show : (a borrow) -> Str in the prelude
plus primitive Show Int / Bool / Str / Float instances. Each
instance body is a single-application lambda invoking the
corresponding runtime primitive (int_to_str, bool_to_str,
str_clone, float_to_str) — first prelude instance bodies to call
runtime primitives directly. Float is included in Show (unlike
Eq/Ord) because textual representation is well-defined modulo the
NaN-spelling caveat at DESIGN.md §Float semantics.
The 22b typeclass test corpus is migrated preemptively: 21 fixture
files and 6 consumer files (typeclass_22b{2,3}.rs +
hash.rs ct4 pin + workspace.rs iter22b1 tests + the
instance_present.prose.txt snapshot) rename class Show / show
to class TShow / tshow, analogous to the existing TEq/TOrd
convention. Migration runs before the prelude additions so the
workspace stays green throughout.
Three new tests pin the post-mono shape: show_mono_synthesis.rs
(existence of show__Int/Bool/Str/Float as Def::Fn entries in the
prelude post-mono module), show_dispatch_pin.rs (bare show and
tshow both Step-2 singletons workspace-globally),
mono_hash_stability.rs::primitive_show_mono_symbol_hashes_stay_bit_identical
(body hashes pinned for the 4 new mono symbols).
DESIGN.md §Prelude (built-in) classes drops Show from the
deferred-features list and appends a milestone-24 paragraph
naming the class signature + the 4 instances + the body shape.
print rewire stays deferred to iter 24.3.
Tests: 552 passed (was 548 + 4 new). bench/compile_check +
bench/cross_lang exit 0. bench/check exits 1 on the recurring
noise envelope per the conservative-call lineage.

iter mq.3: retire MethodNameCollision + multi-class E2E + DESIGN.md sync
Closes the module-qualified-class-names milestone. Deletes the workspace-load workaround; the two-libraries case now resolves via type-driven dispatch at the call site with explicit qualifier as the LLM-author's disambiguation tool. Resolves both mq.2 known-debt items (active_declared_constraints plumbing, (class,method) re-key). New synth warnings channel emits class-method-shadowed-by-fn at all three fn-precedence branches per spec section Class-fn collisions. Three new E2E fixtures + integration tests cover the ambiguous, qualified, and class-fn-shadow trajectories. DESIGN.md class-names paragraph rewritten, new section Method dispatch added. Roadmap P2 marked done, milestone-24 unblocked for re-brainstorm. 9/9 tasks. 545 tests green. bench/compile_check.py + cross_lang.py exit 0; bench/check.py exit 1 (2 noise-class regressions, runtime uncoupled to typecheck iter). |

iter mq.2: type-driven dispatch mechanism installed (mechanism-before-exercise)
Installs the dispatch infrastructure for type-driven method resolution without retiring MethodNameCollision yet. The new multi-candidate path is exercised exclusively by 15 unit tests; real workspaces continue producing single-class residuals (candidates: None) and every pre-mq.2 fixture typechecks unchanged. Three new CheckError variants: - AmbiguousMethodResolution (multi-candidate after type-driven filter) - UnknownClass (explicit qualifier names a class not in registry) - NoInstance gains additive candidate_classes field (Vec<String>) Schema/Env additions: - Env.method_to_candidate_classes: BTreeMap<String, BTreeSet<String>> workspace-flat inverse of class_methods, built in build_check_env. - ResidualConstraint.candidates: Option<BTreeSet<String>> — None preserves pre-mq.2 single-class semantics; Some(set) carries the multi-candidate residual that discharge refines. - ResidualConstraint visibility bumped pub(crate) → pub for unit-test crate access. New helpers: - MethodDispatchOutcome enum + pure resolve_method_dispatch implementing the spec's 5-step rule (qualifier → singleton → type-driven filter → constraint-driven filter → Multi for discharge-time refinement). - parse_method_qualifier splits Term::Var.name into (method_name, optional_qualifier_prefix) at the last dot. - RefineOutcome enum + refine_multi_candidate_residual for discharge-time refinement. - resolve_residual_class_for_mono wires the refinement into mono's collect_residuals_ordered residual-to-target mapping. Synth Var-arm class-method branch rewritten via parse_method_qualifier with inner-dot gate (qualifier must be <module>.<Class>; single-dot names fall through to the existing qualified-fn path). Constraint-discharge in check_fn uses expanded (post-superclass- expansion) constraints for the rigid-var path — sounder than raw declared_constraints. Plan-invented format_type_for_display replaced with the existing ailang_core::pretty::type_to_string (one less duplicate). Synth-time declared_constraints: &[] is a deliberate gap documented as known debt — load-bearing only post-mq.3 for the rigid-var fallback (env-plumbing the active fn's constraints into the Var arm is a ~10-line edit slated for mq.3). 9/9 tasks, 539 tests green (was 520 pre-mq.2; +15 mq.2 unit tests + 4 pre-existing). bench/compile_check.py + cross_lang.py clean; bench/check.py 1 regression (latency noise — runtime cannot be touched by a typecheck-side iter). |

iter mq.1: class-ref canonical-form extension + workspace-internal class-name qualification
Three schema fields move bare → canonical (bare for same-module,
<module>.<Class> for cross-module): InstanceDef.class,
Constraint.class, SuperclassRef.class. Symmetric to ct.1's
Type::Con.name rule. ClassDef.name stays bare.
validate_canonical_type_names gains three field-walks via new
check_class_ref helper + two sibling diagnostics
BareCrossModuleClassRef / BadCrossModuleClassRef.
check_class_name_fields narrowed to ClassDef.name-only.
Workspace-internal class-name keys all qualified:
class_def_module, class_by_name, registry entries.0,
ClassMethodEntry.class_name, class_superclasses, mono's
class_index, Origin::Class.class_name. New qualify_class_ref
helper at workspace.rs scope plus sibling
qualify_class_ref_in_check in ailang-check.
Two new positive on-disk fixtures (mq1_xmod_constraint_class{,_dep})
exercise the qualified Constraint.class shape.
Recon claim that all existing fixtures' class-refs are intra-module
was empirically wrong — 10 fixtures required minimal canonical-form
migration. Duplicate-instance test architecturally restructured:
post-mq.1 orphan-freedom makes two-modules-on-same-(class,type)
structurally impossible; new test_22b1_dup_same_module fixture
lands both instances in the class's module.
Plan defects fixed inline: Origin::Class.class_name single
construction site (plan recon off-by-one); build_class_index in
mono.rs needed qualifying; build_module_globals needed Def::Instance
carve-out; check_fn declared-constraint matching needed inline
canonical-form lifting; NoInstance Float-aware message arm needed
prelude.Eq/prelude.Ord match; coherence type-leg needed qualified-
head split-and-lookup. Tasks 3-6 ran as one coherent fix.
7/7 tasks, 520 tests green. bench/compile_check.py + cross_lang.py
exit 0; bench/check.py exit 1 (4 improvements-beyond-tolerance,
audit-ratifiable, not a regression).
MethodNameCollision + dispatch path unchanged; iters mq.2 + mq.3
land them.

iter 22b.1.2: workspace registry skeleton + coherence checks
Adds the workspace-global typeclass instance registry per Decision 11
"Resolution and monomorphisation". Built at the end of load_workspace
after the DFS over imports completes; keyed by (class-name, type-hash)
where type-hash uses the new canonical::type_hash (16-hex prefix,
parallel to def_hash and module_hash).
Three coherence checks fire from build_registry, each surfacing as a
distinct WorkspaceLoadError variant:
- OrphanInstance: `instance C T` not in C's or T's defining module.
- DuplicateInstance: two entries share the same (class, type-hash) key.
- MissingMethod: instance omits a required (non-default) method.
The CLI's workspace_error_to_diagnostic is extended with the three new
codes (orphan-instance / duplicate-instance / missing-method).
All existing Workspace { ... } construction sites get the new
`registry` field, defaulting to Registry::default() at synthetic /
test-only paths and threading through ws.registry.clone() at codepath
sites that already hold a real workspace.
Includes hash-stability regression tests (iter22b1_schema_extension_*
and iter22b1_classdef_empty_optionals_hash_stable) and the empty-
registry positive test against examples/sum.ail.json. Test count:
288 → 291 (3 new tests, all pass).

check: mode-strict-because suppression (iter 19b)
Closes the 19a/19a.1/19b arc. Corpus signal from 19a.1 (5/65
fixtures fire over-strict-mode, all deliberate RC codegen-test
fixtures) justified shipping the suppress mechanism end-to-end.
Schema: Suppress { code, because } on FnDef. Pre-19b hashes
bit-identical via skip_serializing_if. Typechecker drops matching
diagnostics; empty 'because' is Error severity; wrong codes are
silent no-ops (open-set registry).
Form-A: (suppress (code "...") (because "...")) clause, parser
+ printer round-trip clean. Form-B: '// @suppress <code>: <reason>'
above the doc string, lossless contract metadata.
5 RC fixtures migrated (.ail.json + .ailx + .prose.txt). Corpus
signal: 5/65 -> 0/65. Lint still fires on any future fn that's
accidentally over-strict without an authored reason.
Test counts: ailang-check 55->61, ailang-core 26->28, ailang-surface
21->26, ailang-prose 49->52, e2e 70 unchanged.
Known debt: .ailx comment headers lost on regen (ail render's
contract excludes comments); parse_suppress_attr accepts
duplicate code/because attrs without diagnose (bounded by canonical
print order).
