only Root-anchored parse errors resolved. The table is produced by `parser::parse_file_to_hir` (which depends on `hir`), so the resolver cannot live as a plain tracked fn in `hir`. Add `Db::def_location_table` to `hir` and have the concrete databases (`DriverDb`, test `TestDb`) implement it by delegating to the parser (dependency injection, rust-analyzer `Upcast`-style). Resolution stays at the diagnostic/LSP edge so anchor-relative spans keep the Salsa cache byte-shift-invariant.

Contract members may carry `public` and/or `payable` (in that order); both are rejected on free functions with a clear diagnostic (recovering so parsing continues). Add `constructor(...)` and `fallback(...)` contract members via a new `FuncKind`, and thread `public`/`payable` spans into `FuncSig`. Lifts current-corpus parse coverage from 166 to 270 files.

Model these in the HIR (`ImportSelector`, `SelectedName`, `hiding`, `Export`) and update the import DefId fingerprint so structurally distinct imports keep order-independent identities. Atomic grammar change (HIR signature + parser + lowering + fingerprint); the two touched `.snap`s reflect the new expected-token set, not a regression.

Represent tuples n-ary at the SAIL level: `TypeRefKind::Tuple` holds `Vec`, add `ExprKind::Tuple`, with arity rules `()` -> unit (empty tuple), `(T)` -> grouping, `(A, B, ...)` -> n-ary. The shared `lower_type_list_ref` also fixes multi-field data constructors (`data P = P(a, b)`), which no longer lower to `Error`. (Hull's right-nested-pair encoding is deferred to the backend.)

Emit targeted, recovering diagnostics for each. The negative corpus files `public-constructor.solc`/`public-fallback.solc` now correctly fail. - A parenthesized single pattern `(p)` is grouping, not a 1-tuple — mirror the tuple type/expr arity rule in pattern lowering.

Import paths may start with `@lib` marking an external library root (recorded on the HIR Import and folded into the identity fingerprint), and `@T` in type position desugars to `Proxy(T)` per the reference grammar. The invalid-token fixtures switch to `~` now that `@` lexes. With the dot-constructor work this lifts current-corpus parse coverage to 533 files (93%).

Exports gain the module forms (`export mod;`, `export mod as M;`, `export mod.{items};`) and both import/export selector lists accept constructor selectors (`T(*)`, `T(A, B)`), modeled in the HIR and folded into the identity fingerprints. Resolved against the qualified-import work: external `@` marker plus selector/hiding both feed the import fingerprint. Lifts current-corpus parse coverage to 551 files (95.8%).

Integrating this against the comptime-match-label work created a construction-time cycle (`expr -> pat` via the match-arm guard, `pat -> expr` via comptime labels) that overflowed the stack on any parse; the expression and pattern parsers are now built together via `Recursive::declare`/`define` so the mutual reference is resolved at parse time.

charset=UTF-8 Content-Transfer-Encoding: 8bit Final parser sweep against the reference corpus: qualified types and constructor patterns now take arbitrary-depth qualifiers (`mod.Type.Ctor`), import selector lists may mix `*` with names, `@T`/`@(T, U)` proxy sugar works in expression annotations, and match arm bodies accept block statements. Every remaining corpus failure (13 files) is now a confirmed negative — inputs the reference parser also rejects (contract-only modifiers, fallback arity/return rules, selector alias tails, missing data/class `;`). Parse acceptance: 562/575, full parity with the reference.

All 562 vendored ok files satisfy the stricter check. Five parse-clean semantic-diagnostic fixtures wait in corpus/known-diagnostic-gaps/ until type checking exists.

Import/export validation covers the reference diagnostic catalog (SC0109-SC0120): opaque-by-default data exports, `T(*)`/`T(A,B)` constructor visibility, module re-exports, hiding, and ambiguity/duplicate rules. The driver loads reachable modules from the entry file with the vendored `std/` as the std root.

terms = functions + qualified `Type.Ctor`; fields and module qualifiers separate) with SC0108 duplicate diagnostics, a builtin env mirroring the primitives (word, bool, string, unit, pair, sum, integer, the reserved `Int` class), and a per-body resolver honoring the reference scoping rules: params before body, let-initializers before their binder, match-arm/lambda/block scopes, `for` deliberately not scoping, locals shadowing fields and fields beating same-name functions. Bare constructors report SC0106, `.Ctor` defers to inference, and module-qualified names produce placeholder resolutions for the cross-module pass.

Mon Sep 17 00:00:00 2001 From: Yoshitomo Nakanishi Date: Mon, 6 Jul 2026 21:10:04 +0900 Subject: [PATCH 025/505] Join module interfaces with body resolution across modules MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `module_env` combines a module's own item scope with imports resolved against exporters' public interfaces (per-name aliases, hiding, hidden constructors invisible with partial-data metadata retained, local vs import conflicts enforced, instances flowing independently of exports). The body resolver's import hook and the deferred module-qualified markers now resolve through it — `alias.name`, `alias.Type.Ctor`, imported `Class.method`, nested re-export qualifiers — and the driver renders full name-resolution diagnostics after loading. Validated against the reference imports corpus with expectations from the Haskell test suite: 58/58 expected-pass, 32/36 expected-fail; the 4 divergences are later-phase checks (match exhaustiveness, symlink type identity, typechecked private helpers, pragma validation), recorded as known divergences in the test.

383308acd969701608c192d09a9145cec80171bc Mon Sep 17 00:00:00 2001 From: Yoshitomo Nakanishi Date: Mon, 6 Jul 2026 21:17:17 +0900 Subject: [PATCH 026/505] Update dependencies to latest (salsa 0.27) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit salsa 0.25 -> 0.27.2 (no API fallout for our tracked/interned/ accumulator/cycle-recovery usage), compatible bumps across the tree (annotate-snippets 0.12.16, insta 1.48, url 2.5.8). chumsky stays on the 0.12 stable line — 1.0.0-alpha is a pre-release and not production material. Add rustc-hash to the workspace for the FxHash unification.

This gives LSP-ready per-file grouping with deterministic order, no demand-order dependence, and no side-effect coupling with fixpoint queries. A `Suggestion`/`AnchoredTextEdit` surface is reserved for future quickfixes. The lifetime-free LabelSpan snapshots and edge-only absolute resolution are unchanged — query-level sort keys deliberately avoid absolute offsets; position ordering happens at the render edge. The accumulator path is fully removed; rendered output is byte-identical (no snapshot changes). Atomic API migration across hir/parser/nameres/driver.

Policy now implemented and locked by tests: recovered Error nodes resolve to Resolution::Err silently; a file with parse errors publishes only its parse diagnostics (all nameres kinds suppressed — recovered item boundaries are unreliable, matching the reference which never shows nameres errors alongside parse errors); parse-broken providers are treated as unknown interfaces so importers are not blamed for absence. Parse-clean files keep full diagnostics (positive control).

Diagnostics (lens 4): DiagnosticId hashes level+suggestions, stable sort tie-breaker, content check before absolute resolution in render. Each finding carries a regression test (675 -> 692 tests).

The driver gains --trace and EnvFilter wiring; hot paths stay at trace level with zero cost when disabled.

A BodyTyCatalog carries resolved schemes across the query boundary without leaking inference vars or spans. Typed diagnostics for mismatch/arity/non-word-yul/unknown-field/non-callable/occurs; every class-method use and integer literal emits a deferred obligation for the coming solver.

Instances (plus superclass elaboration and builtin word:Int/integer:Int) become clauses; non-default answers beat default instances and overlapping non-defaults report ambiguity. Inference can now discharge its deferred obligations, recording an evidence tree (Instance{args, sub_evidence} | Builtin) per obligation for the specializer, and emitting typed diagnostics for unsatisfied (SC0207), ambiguous (SC0208), and fuel-exhausted (SC0209) constraints. Soundness conditions and pragma escapes are marked P5 hooks.

lambdas receive the expected function type before body inference; assignments check the RHS against the LHS type; shorthand dot-constructors fail closed (SC0224) on missing/ambiguous expected types; bodies follow the reference result-typing shape (statement types, unified if/match arms, final statement vs declared return, non-final return diagnostic); Yul blocks gain the reference rule set (opcode arity, call/result arity, identifiers, literal kinds).

class arguments unify with substitutions propagated across remaining conditions per the reference byInst; default instances are blocked when any non-default head unifies; imported class origins contribute their superclass clauses to the trait env; superclass derivations record an explicit projection evidence node; local givens take precedence over global instances.

Incrementality: whole-module BodyTyCatalog is replaced by tracked per-definition scheme queries (unrelated signature edits no longer re-run infer_body), deferred obligations solve through a tracked solve_report, TraitEnvId splits into a base env plus local givens. Evidence is addressable per call site via ObligationSource::CallSite for the specializer.

The pragma escapes (no-coverage-condition / no-patterson-condition / no-bounded-variable-condition) suppress globally or per class list, are module-local only (imported pragmas do not leak), matching the reference scoping.

Two root causes fixed along the way: builtin constructors count as dot-shorthand leaves and dot constructors check against concrete builtin expected types. std.solc triaged.

00:00:00 2001 From: Yoshitomo Nakanishi Date: Tue, 7 Jul 2026 04:08:07 +0900 Subject: [PATCH 044/505] Fix solver, alias, and instance-declaration review findings A shared alias-normalization module (cycle and arity diagnostics) now feeds inference unification, numeric/pattern checks, Int obligations, and every solver surface (clauses, goals, givens, signatures). Instance declarations gain the reference checks: declaration-time overlap after normalization, default heads must be type variables, completeness and method-signature conformance against the instantiated class scheme. Solving improvements: instance contexts act as local givens in method bodies, unsolved metavars canonicalize as bindable goal vars instead of grounding to Unknown, superclass projection no longer competes with direct instances, and primitive/ implicit-binder parity matches the reference.

Scoreboard ledger reconciled to reality with typed observed modes, fatal unresolved imports, solver-execution assertions, an instance-soundness backdating regression, and per-family std triage. Frontend parity vs the reference suite: 263/328 (was 198), 65 categorized divergences remain as later-phase inputs.

A tracked per-contract query computes the dispatch surface — ABI signature strings per the reference spelling with placeholder selectors (keccak lands with comptime evaluation), constructor/fallback entries, duplicate-signature diagnostics, and an ABI JSON helper mirroring the reference shape. A tracked desugar plan records if/bool rewrites and storage-access hooks for Hull, which owns physical layout.

calling a non-function value types through an invokable(args, ret) obligation, with builtin function types satisfying it. Generic instances are derived as synthesized clauses with derived evidence, opted out via pragma no-generic-instance-for, and manual instances without the pragma report SC0227. Comptime C3 lands the structural CTC/RTC checks: comptime params demand comptime-known arguments, comptime lets/returns propagate, runtime sources (Yul/storage) are rejected in comptime position, and comptime T stays transparent to typing. Evaluation itself remains P7.

Comptime class-method checking follows selected evidence. Merged with the call-site evidence work: direct calls carry a DirectCallSite while indirect calls keep the invokable lowering path.

modules into a monomorphic IR MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New solcore-specialize crate: an evidence-free Mast-equivalent mono IR (anchor-relative SAIL spans preserved) produced by a driver that walks call graphs from dispatch-surface roots and main, instantiating generics per concrete assignment with reference-style names (map$word), deduped instantiations, and depth fuel. Class-method calls replay recorded call-site evidence — direct instances, superclass projections, derived Generic from/to bodies via derived_generic_plan, builtin/given fallback — leaving no runtime dictionaries; invokable calls become ClosureDispatch entries. Int.fromInteger rewrites per the reference (word -> wordFromInteger, integer -> identity), and free type variables at specialization report the ensureClosed-equivalent error. Comptime/builtin calls pass through for the wave-2 evaluator.

Dispatch surfaces now carry real keccak256(signature)[0..4] selectors via a tracked abi_selector query. The C5 guard rejects integer-typed ids/params/returns surviving evaluation. Backend comptime corpus: 7 positive fixtures fold to their reference verdicts, 6 negatives diagnose; OneOne.solc stays gapped on omitted-return-annotation inference (recorded).

MPTC context-only variables recover from matched instance heads and equality predicates before naming; instance-method names use only the class head main type; closure failures abort the specialization key instead of emitting unchecked types; omitted return annotations specialize from inferred types (closing the OneOne gap); specialized names are module/contract-qualified; mono contracts carry full dispatch metadata (selector bytes, signatures, payability, ABI params) and desugar/storage/closure hooks; C3 obligations ride in mono side tables for the evaluator.

charset=UTF-8 Content-Transfer-Encoding: 8bit Primitive folding keys on resolved MonoCallOrigin (builtin/std identity), never bare names — user functions shadowing builtin names no longer fold; assignments preserve the LHS root and invalidate by target identity; unknown conditionals and match arms evaluate under masked environments with pattern binders shadowing outer constants and merge-invalidation after; comptime enforcement stays active inside comptime-param functions with post-evaluation discharge of LetInit/Return/CallParam/PatternLabel obligations; the erasure guard recurses through every expression, pattern, annotation, argument, scrutinee, condition, and comptime label. Merged with the specializer rework: evidence-resolved calls thread origins alongside the qualified naming and metadata surfaces.

emission from the mono IR reusing derived_generic_plan so ADT layouts match the Generic encoding exactly (nullary unit payloads, right-nested products/sums), bool as (unit + unit), n-ary tuples normalized to right-nested pairs, and match compilation to nested annotated matches with source-constructor comments; a Hull validation pass (annotations, first-order, all paths return/revert); and a pretty- printer locked to the documented .hull syntax via README-example snapshots. Corpus smoke categorizes residual emission gaps (dispatcher plumbing deferred with the reference, which also does not synthesize it).

charset=UTF-8 Content-Transfer-Encoding: 8bit Runtime objects now contain a working dispatcher built from mono dispatch metadata: selector match over calldata, word argument decode, nonpayable guards, the specialized call, and word/product-word return encoding with a reverting fallback (the reference injects SAIL-level dispatch pre-typecheck via std; synthesizing at Hull emission is the equivalent our pipeline supports today — noted in the code). Hull gains loops; unshadowed word-like contract fields lower to sload/sstore slot access; known function/lambda closure callees lower to direct calls. Emission success grows 153 -> 240 of 398 smoke files, with dispatcher and loop residual categories closed and the remainder categorized.

charset=UTF-8 Content-Transfer-Encoding: 8bit The solving engine now implements Selsam, Ullrich, and de Moura's tabled typeclass resolution (arXiv:2001.04301, the Lean 4 algorithm): a per-query table of canonical goals holding deduped abstracted answers and registered consumers, generator nodes iterating ordered clauses (givens, non-default instances, superclass projections; defaults in a second phase), consumer nodes suspended on subgoal entries, and a worklist that replays every answer to every consumer — late consumers receive prior answers on registration. Cycles saturate and diamonds share entries, both asserted by tests (no fuel diagnostics fire; solver stats exposed through SolverReport). The recursive active-goal guard is gone; the reference semantics layer (ambiguity, defaulting, given precedence, evidence trees, salsa keying) is unchanged. Also removes a stray committed test file.

non-exhaustive matches emit compile diagnostics. Single-constructor matches project payloads from the scrutinee (no synthetic unbound binders), recursive ADT layouts are cycle-safe via named layout references, and logical not lowers as a bool-sum branch swap. Emission crashes drop to zero on the smoke corpus.

Runtime dispatch gates behind calldatasize() >= 4 with short calldata routed to the fallback, static-arg calls verify the ABI head size (revert 0x08638556), and unsupported public selectors are hard emission diagnostics instead of silent revert arms. Match-lowering tests tolerate dispatch-eligibility diagnostics, which are covered by their own suite.

charset=UTF-8 Content-Transfer-Encoding: 8bit The checker gains the reference assembly model — Yul local scopes, return counts, call and usr$ arity, word-only arguments, and the full raw Yul builtin table including the deployment builtins — plus Bool enforcement on for-conditions, terminal Yul return/revert in terminator analysis with unit-return relaxation, and verification of expression type annotations against inferred types (mismatch diagnostics). The pretty-printer emits the reference parenthesized for-loop form.

charset=UTF-8 Content-Transfer-Encoding: 8bit Every TypeckDiagnostic variant now snapshots anchor-relative LabelSpans at creation — expression spans for mismatches, both sites for conflicts, signature spans for arity and annotation errors, instance heads for the soundness conditions, obligation sources for solver diagnostics, and comptime obligation sites — and lowering attaches primary/secondary labels, so CLI output renders caret snippets. Driver e2e tests assert the snippets for SC0201, SC0207, and SC0212.

charset=UTF-8 Content-Transfer-Encoding: 8bit Expectations now cover all 577 corpus files — cases, spec (incl. attic), comptime, dispatch, invokable, top-level examples, imports, and diagnostics — each section citing its reference-suite source, with inferred classifications marked. The scoreboard discovers the full corpus, runs the complete frontend with std/@extlib-aware loading, and reports per-area parity: 340/423 expected-pass and 134/154 expected-fail in parity, 103 divergences recorded non-stale (dispatch/ invokable areas dominated by specializer/std-instance dependencies).

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New dev-only solcore-uitest crate owns ALL failure-case testing: stage-organized fixture trees (parse/nameres/typeck/solver/comptime/ specialize/hull) driven by dir-test with insta snapshots of the rendered, path-normalized diagnostics — migrated from the parser hand-written fail fixtures, nameres failure tests, and the inline negative tests scattered through hir-ty/specialize/hull. hir-ty OK cases become ordinary dir-test fixtures asserting a clean full frontend. A shared solcore-test-utils crate provides the frontend TestDb, std-aware fixture loading, and the deterministic renderer, replacing duplicated test scaffolding. The corpus parity scoreboard and incremental event-log harnesses stay separate concerns. Net +38 tests (63 consolidated, 101 added).

charset=UTF-8 Content-Transfer-Encoding: 8bit An exhaustive audit of the reported defect classes drove three mechanism fixes, no special cases: (1) error poisoning — InferTy::Error absorbs unification in both directions and every emitted diagnostic poisons its expression, so one user error yields one diagnostic (the Opt.None(1) cascade collapses to the single arity error); (2) failed obligations classify by source and concreteness before lowering — integer-literal obligations on concrete non-numeric types report a mismatch at the literal instead of constraint noise, non-callable call sites report NonCallable, and PredKind::Eq commits real unification instead of manufacturing Int obligations; (3) value positions classify Resolution exhaustively — type/class/module/ type-var names used as values are typed errors (SC0228), class-as-type diagnoses (SC0229), and nothing falls open to fresh variables. Unresolved inference variables render as _ in all user-facing output. Fifteen audit fixtures lock the matrices in uitest; corpus parity improved (fail-parity 135, divergences 102).

charset=UTF-8 Content-Transfer-Encoding: 8bit New solcore-yul crate: a Yul AST with strict-assembly printing (objects, code/data blocks, switch/if/for, hex and string literals) and Hull lowering per the reference ToYul scheme — words as stack values, products flattened to component slots with shape-preserving projections, sums as tag plus padded payload (boolean tags for binary sums, numeric for in(k)), match as switch, and inline assembly substituting Hull variables to generated locations. The driver gains --emit-yul and --emit-hull (stdout or file) with CLI regressions, and golden snapshots lock the doc examples. All 254 Hull-clean corpus files translate with zero Yul failures.

Yoshitomo Nakanishi Date: Tue, 7 Jul 2026 14:08:47 +0900 Subject: [PATCH 066/505] Execute emitted contracts on a real EVM end to end MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A gated (E2E=1) harness compiles emitted Yul with solc --strict-assembly, deploys through anvil, calls main() or dispatch selectors via cast, and compares decoded returns against the reference-suite expectations. All 14 configured programs — 13 spec files plus a selector-dispatch contract — pass on-chain; 42 Yul-translating files await recorded expectations.

charset=UTF-8 Content-Transfer-Encoding: 8bit if-expressions evaluate only the selected branch — statements and copies live inside their own switch arms (a deliberate semantic deviation from the reference's inherited eager pattern); InK lowers through nested binary Inr/Inl preserving layout with copy arity enforced; inline-assembly substitution is shadow-aware through lets, params, returns, and nested blocks; top-level Hull programs assemble per the reference with an OutputDeploy wrapper and _mainresult return.

Yoshitomo Nakanishi Date: Tue, 7 Jul 2026 15:13:28 +0900 Subject: [PATCH 068/505] Make emitted Yul strict-assembly safe MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Hygienic naming (AsmScopes) for every identifier — source variables, params, returns, and inline-assembly declarations/lvalues — avoiding Yul builtins, reserved words, and literal names, with assembly shadowing resolved locally before outer substitution; strict rendering enforces one top-level object per file with --emit-yul-object selection and a listing diagnostic for multi-contract input; decimal literals canonicalize (no octal-looking forms) and hex validates; break/continue placement is validated. solc --strict-assembly acceptance over all snapshots and shadowing repros is locked in a gated test. Also repairs the two stale doc snapshots from the lazy-if lowering.

Tue, 7 Jul 2026 15:29:16 +0900 Subject: [PATCH 069/505] Widen the E2E harness with a blocked-gap ledger The dispatcher accepts ABI bool as a canonical 0/1 static word, the harness decodes bool and multi-word product returns, selectors derive from the compiler ABI metadata instead of hardcoding, constructor calldata is size-guarded, and anvil lifecycle/timeout/log handling is hardened. The expectation manifest grows to 52 executed programs with the 36 reference-derivable-but-pipeline-blocked files recorded as categorized blocked entries (unannotated-entry-specialization 13, non-word-abi-dispatch 19, needs-std-instances 4) that fail the harness when stale; 16 programs pass value parity on a real EVM, unknown files still fail.

charset=UTF-8 Content-Transfer-Encoding: 8bit Inferred body types now flow into function_scheme and contract dispatch lowering when a legacy entry omits its return annotation, so spec-style 'public function main() { return 42; }' entries specialize with closed types instead of failing FreeTypeVariable — without relaxing ensure_closed or the SignatureRequirement::Complete negatives. Three E2E entries move from blocked to passing on real-EVM parity.

contract ABI resolution follows imported std types, and match pattern binders materialize before branch bodies (unblocking assembly uses).

Constant match folding compares constructors by normalized canonical identity with matching types instead of raw strings, fixing three real-EVM value miscompiles (dwarves/food0/food returned the wildcard arm); tree-shape and value regressions lock the behavior.

Key the guard on (DefId, args) — same-instantiation recursion still hits the guard; different instantiations expand structurally, matching the reference's translateTCon substitution. - encode_constructor derived injection depth from the type structure (sum_arity through strip_named), counting a sum-typed payload as extra constructors and emitting a spurious inl. Bound the recursion by the ADT's constructor count like the reference's encodeCon, which peels one sum level per remaining constructor and never walks payloads.

deliberately superseded by 02nid.solc. - 052negPair.solc: legacy inline instance-context syntax was removed from the reference grammar; after syntax modernization the reference still rejects incomplete instance-method signatures, matching our SC0226 policy; superseded by 11negPair.solc. - 101struct1Field/102uintField/103struct3Fields/105nestedStruct/ 111storageStruct: class heads lack forall binders (rejected since upstream commit 7ad5622); pre-std experiments superseded by std/assign.solc's StructField machinery. Introduce SpecExpectation::Neg { reason } in the E2E harness: a Neg fixture must produce at least one pipeline diagnostic to count in the new neg-parity scoreboard bucket; if it unexpectedly compiles it is reported as a stale negative and the harness fails, so drift is caught exactly like stale blocked entries. Empty Neg reasons are rejected by spec_cases() and the manifest coverage test asserts the new variant. Flip the seven expectations.txt lines to expected-typecheck-FAIL (solcore-rs already emits diagnostics for all seven) and delete the now-satisfied known! divergence entries in the same commit so the stale_known assertion stays clean.

Ground goals still report immediately, and a final phase re-solves the remaining deferred goals in ascending obligation order with today's diagnostics. Evidence, call-site evidence, and diagnostics stay sorted by obligation index so round interleaving cannot perturb downstream consumers. This makes callee-first obligations like `?lhs:Assign(word)` wait for the argument-side goal that improves ?lhs (the 113counter pattern), and it parity-fixes seven std-importing corpus fixtures plus std.solc's own ordering-induced SC0207 family, whose stale known-divergence entries are dropped from the reference scoreboard.

Only three unqualified forms are legal: primitive constructors (true/false/()/pair/inl/inr), constructors sharing their type's name, and leading-dot shorthand. solcore-rs previously bound lowercase nullary user constructors in pattern position as fresh local binders (first arm always matches, silent wrong code) and resolved bare constructor leaves in expression position to DotCtorDeferred, which later died as an internal Hull UndefinedVariable instead of a source diagnostic. Wire up the previously dead NameresDiagnostic::UnqualifiedConstructor: - PatKind::Var: keep builtin true/false interception, resolve same-name constructors, reject other in-scope user constructor leaves, and only then bind a local. - PatKind::Ctor (unqualified): keep primitive leaves on DotCtorDeferred, reject user constructor leaves that are not same-name. - resolve_ident/resolve_call_ident: drop the bare-identifier DotCtorDeferred fallback; report SC0106 where the name would otherwise be undefined, matching the reference's catch-all order (types and modules still win).

Teach the two Var-pattern consumers to honor that resolution instead of binding a fresh local: hir-ty infers it through the regular constructor-pattern scheme (and poisons Resolution::Err patterns already reported as SC0106), and the specializer lowers it to a nullary MonoPatKind::Con so match folding and codegen discriminate on the constructor.

Mirror the reference's NameResolution desugaring exactly: `+` and `-` elaborate as qualified Add.add/Sub.sub class-method calls, `>` as Ord.gt, while `<`, `<=`, `>=` resolve the plain lt/le/ge functions through normal import-sensitive scope (which is why ltproxy imports std.{lt} and why the reference rejects dispatch/fib.solc, now tracked as an expected failure). Specialization replays the operator evidence so instance-dispatched operators lower to specialized method calls. Indexed compound assignment keeps a conservative word/uint/uint256 gate: its lowering is still raw word add/sub, so only element types whose instances coincide with the primitive are accepted. *, /, %, bitwise, ==, !=, &&, || remain on their existing word/bool paths; their ADT-operand behavior still diverges from the reference operator table and is tracked for follow-up.

From 8ac8927e3e41614c61ddd6be4699578a6d11e684 Mon Sep 17 00:00:00 2001 From: Yoshitomo Nakanishi Date: Wed, 8 Jul 2026 11:01:34 +0900 Subject: [PATCH 112/505] Wrap out-of-range word literals to 256 bits in Hull backend Word literals >= 2^256 were emitted raw into Yul, producing invalid literals; the reference masks them to value mod 2^256 (2^256 -> 0). Add a shared Hull word-literal helper and apply it when emitting numeric word expressions, when building match decision trees (huge pattern literals), and in Hull-to-Yul translation.

Root result literals and integer patterns still default to word where the reference permits. Also close the SC0240 hole where generic helpers forward runtime values into comptime class-method parameters.

With defaulting deferred past class solving, those literals need the std word:Int instance on the module path. Route these tests through a std-aware specialize helper (writing the source under a temp main root) and update the mangled-name assertions to the resulting main_ module prefix. The emitted Hull is unchanged and still materializes the storage slot before the RHS.

From fb275dd95cac239758b400f14cdbd13c51243a0c Mon Sep 17 00:00:00 2001 From: Yoshitomo Nakanishi Date: Wed, 8 Jul 2026 11:54:32 +0900 Subject: [PATCH 124/505] Enforce complete function signatures Align top-level and contract function signature checking with the ac6f8957 reference by emitting SC0220 for incomplete signatures unconditionally. Remove the require-annotation filename gate and renumber incomplete-instance diagnostics from SC0220 to SC0244 to avoid the reference code collision.

Remove two hir-ty ok fixtures (spec/010answer, spec/011id) that the ac6f8957 reference now rejects with SC0220, and repoint downstream specialize/hull/yul/hir-ty tests at reference-passing fixtures or in-memory sources where they previously used programs the current reference rejects.

semicolon-less `data` decls in existing fixtures were given explicit `;`.

keep input/path options as OsString/PathBuf so a non-UTF-8 path argument yields a clean IO error instead of a panic - name the missing external-lib root (with a fix-it note) when a reachable import resolves through a missing/not-a-directory configured root - add reference-compatible flags: -f/--file, --unicode, --diagnostic-width, --warnings, and real --abi emission (via hir_ty::contract_abi_json) honoring -o Defers --type-class-resolution/--pe-fuel and the DriverDb salsa-input rewrite (proposals recorded).

add conservative edit-distance "did you mean" suggestions for unresolved names/imports/modules; point missing-module errors at the path token; add a private-declaration secondary label + note; give value-as-type and unqualified-constructor errors concrete fix-it help; suppress bad-import follow-on cascades.

bare `string` return type now rejects with SC0103 - type contract storage fields as storage(T) and read/assign through visible CanStore, so storage(string)/storage(bytes) roundtrips typecheck - a whole contract-field mapping read keeps type storage(mapping(..)), so returning it as a bare mapping rejects with SC0201 - reserve generated dispatch type names;

Derive the concrete type directly (storage(mapping)->storage(mapping), storage(string|bytes)->memory(..), storage(t)->t) while keeping the CanStore obligation for validation, and record concrete base-ref types for indexed storage assignments.

charset=UTF-8 Content-Transfer-Encoding: 8bit The module doc still claimed a "minimal" solver that "only consumes the resulting clauses" and left instance soundness as "hook points" — both stale: the solver is a full tabled-resolution engine and the coverage/Patterson/ bounded-variable checks are implemented in instance_soundness_diagnostics. Rewrite the module doc to describe the actual engine (canonicalized subgoal tables, generator/consumer nodes, answer deduplication, diamond sharing, cycle termination, fuel backstop), document the previously-undocumented engine types and pivotal methods, and cite the tabling approach it follows: Selsam, Ullrich & de Moura, "Tabled Typeclass Resolution", arXiv:2001.04301. Comments only; no behavior change.

mod.rs re-exports the public surface so hir_ty::contract::* paths and all tracked queries are unchanged. Move-only; ABI JSON bytes and dispatch order preserved, 1074 tests green, clippy clean.

Move-only; anchor-relative query_sort_key kept distinct from absolute edge sort_key (no absolute-span resolution in tracked paths), diagnostic IDs and render output byte-identical, 1074 tests green, clippy clean.

Move-only; tracked queries unchanged, 1074 tests green, clippy clean.

Move-only; import/export/diagnostic ordering preserved, 1074 tests green, clippy clean.

mod.rs re-exports the public surface. Move-only; answer ordering, default-instance priority, and ambiguity reporting preserved, 1074 tests green, clippy clean.

Tabling memoizes each distinct (canonicalized) subgoal in a `TableEntry` +//! that records both the answers found so far and the consumers suspended on +//! it: +//! +//! - a `GeneratorNode` resolves the program clauses applicable to a subgoal +//! (local givens, instances, superclass projections, and — only when nothing +//! else applies — default instances) one at a time, producing answers; +//! - a `ConsumerNode` is a partially-solved clause suspended on one of its +//! condition subgoals; it resumes (`WorkItem::Resume`) once per answer that +//! subgoal yields, threading the answer's substitution and evidence; +//! - `produce_answer` admits an answer only when an equal one is not already +//! tabled (the paper's answer-subsumption step, here exact-duplicate +//! elimination on the canonical substitution), so duplicate answers are never +//! stored or re-propagated. +//! +//!

charset=UTF-8 Content-Transfer-Encoding: 8bit Decompose the largest file in the codebase — the 11773-line Hindley-Milner inference engine — into cohesive submodules: table (ena-backed InferTy unifier), ctx (InferCtx state + root/finish/scopes), stmt, expr, storage, pattern, coverage_adapter, yul (inline-assembly inference), unify, obligations (obligation solving + defaulting + evidence), schemes (tracked scheme queries), comptime (ComptimeChecker), diagnostics, lookup, tests; mod.rs re-exports all hir_ty::infer::* items and impl InferCtx is split across modules via pub(super). Move-only; tracked scheme queries and cycle recovery unchanged, no absolute-span resolution added to tracked code, 1074 tests green, clippy clean.

parse/mod.rs keeps parse_supported_items and parse_body_statements as the pub(crate) facade. Move-only; chumsky recovery order, error messages/notes, and absolute LexSpan handling byte-identical (664 parser tests incl. incremental_spans and def-identity green), 1074 workspace tests green, clippy clean.

mod.rs keeps module name `evaluate` and re-exports EvaluateOptions/evaluate_module. Move-only; bigint/word semantics, keccak, and fuel accounting byte-identical, 1074 tests green, clippy clean.

mod.rs keeps module name `specialize` and re-exports specialize_module/specialize_name. Move-only; specialization queue order, mono/mangled names, and right-nested sum encoding byte-identical, 1074 tests green, clippy clean.

e283e8d104e13908d11d0344a6128af1b2609afc Mon Sep 17 00:00:00 2001 From: Yoshitomo Nakanishi Date: Wed, 8 Jul 2026 17:52:06 +0900 Subject: [PATCH 155/505] refactor(hull): split emit.rs (4.9k) into emit/ modules Decompose the 4911-line SAIL->Hull emitter into cohesive submodules: emitter (core Emitter + stmt/expr lowering), contract, dispatch (selector dispatcher + ABI cleaning + nonpayable checks), abi (encode/decode), storage (StorageLowerer), match_compile (decision-tree compilation), layout (bool-as-sum/word-slot/shape helpers), yul_build, reachability (deployment closure), diagnostics; mod.rs re-exports emit_module and the public surface. Move-only; ABI/selector order, $altN match naming, dispatcher, and deployment-object bytes byte-identical, 1074 tests green, clippy clean.

charset=UTF-8 Content-Transfer-Encoding: 8bit Decompose the 1950-line Parsed->HIR (SAIL) lowering into cohesive submodules: context (LoweringCtx + DefId allocation), span (anchor-relative span helpers), fingerprint (structural DefId fingerprints), items, body, yul; lower/mod.rs keeps parse_file_to_hir_impl as the sole crate entry. Move-only, with DefId allocation order, owner chains, anchor base offsets, and structural fingerprints kept byte-identical — the def_identity (11), incremental_spans (2), and lowering_regressions (8) suites stay green, so Salsa cache stability is preserved. 1074 tests green, clippy clean.

The two distinct module-for-def lookup flavors are unified into named helpers (module_for_def_via_graph vs via_tree) in a new hir-ty support module, kept separate because they resolve via module_graph vs module_tree respectively. The tracked module_for_def query keeps its identity and delegates to the graph helper. Behavior-preserving, 1074 tests green, zero snapshot changes, clippy clean.

Add a DiagnosticCode registry so phase code() methods return named constants, plus a test that rejects undocumented duplicate SC codes (intentional aliases allow-listed). All emitted code strings and diagnostic ordering byte-identical; 1075 tests green (adds the registry test), zero snapshot changes, clippy clean.

00:00:00 2001 From: Yoshitomo Nakanishi Date: Wed, 8 Jul 2026 19:15:36 +0900 Subject: [PATCH 159/505] refactor(specialize): add Mono-IR visitor, dedup traversal Add ir::visit with a Visitor trait and walk_stmt/walk_expr/walk_pat that encode the Mono IR child-traversal order once, then migrate the read-only analyses (dead-code call collection, type-reg collection, pattern binders, purity, write-effects, storage-index detection, integer-erasure traversal) onto it. Scope-sensitive collectors that track locals/branch binders per arm are deliberately left with bespoke traversal. Traversal order preserved, behavior-preserving, 1075 tests green, zero snapshot changes, clippy clean.

InferTable now holds &dyn Db so inference diagnostics share the same formatter. AST-syntax formatters (format_type_ref) are left separate as they render parsed syntax, not semantic Ty. Diagnostic text byte-identical, 1075 tests green, zero snapshot changes, clippy clean.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace ItemRef.constructors: Option> — a three-state sentinel (None=not-data, Some(empty)=opaque, Some(set)=visible) — with an explicit ConstructorVisibility { NotData, OpaqueData, Visible(_) } enum, where Visible wraps a non-empty VisibleConstructors so Visible(empty) is unrepresentable. All ItemRef construction and import/export/re-export constructor filtering migrated. The public Interface/ModuleEnv constructor_visibility maps and partial_data (consumed outside nameres) are left as-is and populated from the enum with identical behavior.

From f4f19a6517d522d9e290da4b42909dcc35cf7c60 Mon Sep 17 00:00:00 2001 From: Yoshitomo Nakanishi Date: Wed, 8 Jul 2026 20:25:24 +0900 Subject: [PATCH 164/505] refactor: collapse seven assignment variants into Assign{op} Replace the seven duplicated `{ lhs, rhs }` assignment statement variants (Assign/AddAssign/SubAssign/BitXorAssign/BitAndAssign/BitOrAssign/ModAssign) in both HIR StmtKind and mono MonoStmtKind with a single Assign { op, lhs, rhs } carrying an AssignOp { Plain, Add, Sub, BitXor, BitAnd, BitOr, Mod } (reused across both IRs). The parser maps its assign token to AssignOp during lowering; all readers (hir-ty inference/comptime/desugar, specialize body/ evaluator/visitor, hull emit) migrate to a single match. Hull/Yul plain assignment surfaces are left unchanged (no compound ops there). Operator semantics byte-identical, 1075 tests green, zero snapshot changes.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace unreadable positional bools with named enums: allow_contract_modifiers -> FunctionContext{Module,Contract} (parser), and nameres strict -> ExportResolutionMode{Lenient,Strict}, include_data_ctors -> CtorInclusion, and parse-error suppression -> BodyDiagnosticPolicy. The tracked body_diagnostics query keeps its bool parameter (salsa identity rule). Purely an ergonomics/type change — same branch taken for the same policy; parser corpus and nameres module-system snapshots byte-identical, 1075 tests green, clippy clean.

charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce a ModuleFsSnapshot salsa input (existing_files + sibling_stems) and make the tracked resolve_module_path query pure over it: the std-vs-local fallback disambiguation and module-not-found suggestions now read the snapshot instead of live is_file()/read_dir() calls. The driver and test DBs populate the snapshot from the real filesystem during pre-load discovery (untracked context). This removes a latent LSP staleness hazard — file add/remove now correctly invalidates the narrow module-resolution dependency instead of leaving stale live-FS observations cached; no std::fs/is_file/ read_dir/exists call remains reachable from any tracked nameres query. Behavior byte-identical (same modules resolved, same fallbacks, same suggestion text); adds an incremental_cache proof test showing a sibling snapshot edit re-executes resolution and updates the suggestion. 1076 tests green, incremental_cache/incremental_spans suites green, zero snapshot changes, clippy clean.

Add ItemScopeFacts/ItemScopeDiagnostics and ItemResolutionFacts/ItemResolutionDiagnostics (the existing structs stay as compatibility composites that deref to facts), a ModuleImportSurface, and facts-only queries (item_scope_facts, resolve_item_type_facts, module_import_surface, item_resolution_facts_for_module). Type lowering, alias normalization, schemes, trait-env, generic derivation, contract dispatch, and body resolution now consume the facts; diagnostic aggregation keeps using the composites. This decouples inference from diagnostic churn: an edit that only shifts an import-conflict diagnostic's span no longer re-runs body inference. Adds a proof test (import_diagnostic_span_edit_does_not_rerun_unrelated_body_inference: infer_body executions 2 -> 0 after a diagnostic-only edit). Output byte-identical, 1077 tests green, existing incremental assertions unchanged, zero snapshot changes, clippy clean.

Centralize the non-empty scope-stack invariant in a ScopeStack helper across emit/check/storage. Decision-tree algorithm and generated Hull/Yul ($altN order/names) byte-identical; 9 hull snapshots green, clippy clean.

a debug_assert keeps a real invariant break visible in debug builds. Well-formed indexed programs are unaffected (accessors succeed). Unrelated invariant panics left as-is. No new diagnostic text; output for valid programs byte-identical.

ABI writer; ty helpers Add InferCtx::emit_expr_error/emit_pat_error/emit_error_with_poison so a diagnostic and its expr/pat poison are emitted together (preventing a missed poison that would change cascade behavior), and migrate the repeated push+poison sites. Replace infallible write!(String).unwrap() in ABI JSON rendering with push helpers while still propagating real component-validation errors. Add InferCtx::{unit,word,bool,string} helpers for the repeated primitive-type construction. Cascade behavior and ABI JSON byte-identical, incremental_cache green.

The final solver clause order is preserved EXACTLY (builtins, superclass modules in unique_modules order, instance origins in env.instances order, then derived Generic), so tabled-SLG answer ordering, default-instance priority, superclass non-competition, and evidence selection are byte-identical. Editing one imported instance now reuses the interned builtin/superclass/other-instance/derived subsets instead of rebuilding the whole environment key.

Selection behavior is byte-identical: is_default was only ever true for Instance clauses, so the new `ClauseOrigin::is_default()` helper preserves answer_priority (default-instance=3, superclass=2, else=1, local-given short-circuit=0), answer_root (DefaultInstance vs Instance), evidence construction, and clause filtering. same_table_answer drops the now-redundant is_default term because a given instance def is uniquely default-or-not, so origin equality subsumes it. ProgramClause is a #[returns(ref)] field of the salsa-interned TraitClauseSetId; the fold is bijective on previously distinguishable states, so interned-clause set identity is preserved. soundness.rs check_default_instance_head (unrelated InstanceDef bool) left untouched. 96 hir-ty tests green.

Two distinct enums (not a shared one) to keep param vs let free to diverge. The HIR->mono rule (param_comptime(param) || ty_is_comptime(db, ty)) is preserved verbatim, only wrapped in ParamMode::from_bool. Evaluator, erasure, and the hull emitter read via is_comptime(); the "comptime parameter" diagnostic string is unchanged. bool<->2-variant is value-isomorphic and mono IR carries no salsa/interned identity, so behavior and diagnostics are byte-identical. 69 specialize+hull tests green.

The raw `check_duplicate: bool` threaded through add_* is gone. Builder-internal only: finish() still yields plain Vec, so stored ItemScopeFacts/ContractScope types and all downstream/salsa surfaces are unchanged. Duplicate diagnostics (SC0108) keep identical spans, first-wins "previous declaration" anchor, and contract-name context; add_module's silent first-wins dedup preserved. 190 uitest snapshots unchanged.

The index is derived deterministically from insertion order, so Eq/Hash/salsa::Update stay a pure function of the ordered entries and salsa memo identity of the tracked item_scope/item_scope_facts queries is preserved.

The resolver's if leading_dot.is_some() / else-if qualifier / else chain becomes a match on head with each branch body preserved verbatim; behavior is identical because the parser never emits dot+qualifier together (expr_pat sets exactly one), so the enum faithfully represents every reachable state. Parser-owned ParsedPatKind::Ctor is left unchanged; lowering builds the head. PatKind is salsa-tracked FuncBody arena data (not a key); PatCtorHead derives salsa::Update and preserves spans verbatim, so span anchoring is unaffected.

The mono layer already carried selectors as [u8;4], so the specialize driver drops the fragile selector_bytes(&hex).expect(...) parse-back and reads method.selector.0 directly; the now-dead selector_bytes helper and its re-export are removed. AbiSelector::to_hex reproduces the exact canonical lowercase 0x+8-hex string for the two callers that still want it (test assert, e2e cross-check). abi_selector stays #[salsa::tracked] over the interned AbiSignature key; the value type changes from String to a Copy [u8;4] wrapper with no cache-identity impact.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the stringly-typed AbiParam.ty / MonoAbiParam.ty (String) with an AbiType enum { Uint256, Bool, String, Unit, Tuple, Named(String), Unsupported } whose Display reproduces every current canonical string byte-for-byte (uint256/bool/string, empty for Unit, "tuple", the user type name — or the {:?} kind fallback — for Named, ""). The ABI-JSON renderer writes ty.to_string() into internalType and type, and the "" string sentinel checks become matches!(.., AbiType::Unsupported). Hull's ABI layout predicates (is_dynamic/_static_word/_address/_bool and the "tuple" check) become AbiType matches that preserve the exact builtin-vs-user-name behavior (e.g. a user type named "bool" still matches both the builtin Bool and Named("bool")). All new types are return-value-only in tracked contract_dispatch_surface queries (not keys) and derive salsa::Update+Hash; mono is salsa-free. 355 hir-ty+specialize+hull+uitest tests green, ABI-JSON and Yul snapshots unchanged.

charset=UTF-8 Content-Transfer-Encoding: 8bit Pure mechanical rename of the MonoCallOrigin::Unknown variant to ByName. "Unknown" wrongly implied an unresolved/error state — it is in fact a fully RESOLVED, name-only call origin (resolved operator overloads, evidence- resolved class methods/invokables, int fromInteger, builtins whose kind maps to no intrinsic, and closure-dispatch to a known function); genuinely unresolved calls use MonoExprKind::Error/ClosureDispatch instead. Every producer and the explicit match arms are renamed; the intentional asymmetric grouping is preserved verbatim (call_name keeps Source|ByName => name; display_call_name keeps Builtin|ByName => backend symbol). Zero behavior change; emitted Yul and diagnostics byte-identical, 259 tests + snapshots green. NOTE: the audit's FL3-12 goal (drop the variant / publish only {Source, Builtin} or fold into Error) was verified NOT behavior-preserving — the two consumers group this variant asymmetrically (Source-like in emit, Builtin- like in erasure) so no 2-variant collapse preserves both surfaces, and folding to Error would delete codegen for correct programs. This rename is the behavior-preserving kernel; the structural split is deliberately not done.
