For every `view` function in a `verity_contract`, the macro now auto-generates a `@[simp]` theorem `_is_view` stating: FunctionSpec.isView (_model) = true This is provable by `rfl` because the macro already sets the flag. The `stmtWritesState` validation in `Validation.lean` guarantees the body contains no state-writing statements, so the flag accurately reflects the function's behavior. Changes: - Specs/Common.lean: add `viewPreservesState` predicate (full state unchanged frame condition, covering all storage + context + events + knownAddresses) with `@[simp]` reflexivity theorem - Macro/Bridge.lean: add `mkViewTheoremCommand` that generates the `_is_view` simp lemma for a view function - Macro/Elaborate.lean: call `mkViewTheoremCommand` in the per-function loop for view functions - MacroTranslateInvariantTest.lean: compile-time assertion that the `MutabilitySmoke.currentOwner_is_view` theorem exists Verified: `lake build` succeeds, `make check` passes, all existing contracts (ERC20, Vault, SimpleToken, Ledger, etc.) unaffected.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add a `types` section to the verity_contract grammar that lets users declare semantic newtypes (e.g. `TokenId : Uint256`). At the language level the types are distinct identifiers; at the EVM/Yul level they are erased to their base types (zero overhead). Changes: - Syntax.lean: declare verityNewtype syntax category, add optional `types` section before `storage` in verityContractCmd - Translate.lean: NewtypeDecl structure, parseNewtype with scalar-only validation, thread newtypes array through all parse* and valueTypeFromSyntax functions, resolve unknown idents against newtypes before erroring - Elaborate.lean: destructure the new newtypes return value - Smoke.lean: NewtypeSmoke test contract (TokenId, Amount, Owner) with #check_contract - MacroTranslateInvariantTest: specs, signatures, selectors, theorems - MacroTranslateRoundTripFuzz: specs - generate_macro_property_tests.py: parse `types` section, resolve newtypes to base types in function params/return types - PropertyNewtypeSmoke.t.sol: auto-generated property tests Co-Authored-By:

Binds a success flag (0/1) to successVar and return values to resultVars. The caller is responsible for checking the success flag and handling failures. Source-level syntax: let (success, result) ← tryExternalCall "echo" [x] -- single-return let (success, a, b) ← tryExternalCall "fanout" [x] -- multi-return let success ← tryExternalCall "voidFn" [x] -- zero-return Compiles to Yul call to {externalName}_try which returns (success, result...) instead of reverting on failure. Also lifts the multi-return external restriction — externals with multiple return values are now allowed; the auto-revert expression form (externalCall) still requires single-return but tryExternalCall supports any return count.

emit adtTypes in spec - Update AdtSmoke: ADT-typed storage field + rfl assertions proving spec.adtTypes carries both type definitions with correct variant counts Co-Authored-By: Claude Opus 4.6 --- Contracts/Smoke.lean | 12 +++-- Verity/Macro/Elaborate.lean | 4 +- Verity/Macro/Translate.lean | 97 +++++++++++++++++++++++++------------ 3 files changed, 78 insertions(+), 35 deletions(-) diff --git a/Contracts/Smoke.lean b/Contracts/Smoke.lean index 1ca5e6974..8e250e949 100644 --- a/Contracts/Smoke.lean +++ b/Contracts/Smoke.lean @@ -1905,10 +1905,10 @@ example : CustomNamespacedSmoke.owner.slot ≠ 1 := by decide example : CustomNamespacedSmoke.balance.slot ≠ NamespacedStorageSmoke.balance.slot := by decide example : CustomNamespacedSmoke.spec.storageNamespace.isSome = true := rfl --- ADT (inductive) section smoke test (#1727, Axis 1 Step 5a) +-- ADT (inductive) section smoke test (#1727, Axis 1 Steps 5a/5b) -- Declares algebraic data types with typed variant fields. --- At this step the ADTs are parsed and validated but not yet used in IR --- generation (that is Step 5b). +-- ADT type definitions flow through to ContractSpec.adtTypes. +-- ADT-typed storage fields are represented as Uint256 (tag value) at the EVM level. verity_contract AdtSmoke where types TokenId : Uint256 @@ -1917,6 +1917,7 @@ verity_contract AdtSmoke where Result := | Ok(amount : Uint256, recipient : Address) | Err(code : Uint256) storage counter : Uint256 := slot 0 + result : OptionalUint := slot 1 function increment () : Unit := do let current ← getStorage counter @@ -1924,6 +1925,11 @@ verity_contract AdtSmoke where #check_contract AdtSmoke +-- Verify ADT type definitions flow through to spec (#1727, Step 5b plumbing) +example : AdtSmoke.spec.adtTypes.length = 2 := rfl +example : AdtSmoke.spec.adtTypes.map (·.name) = ["OptionalUint", "Result"] := rfl +example : (AdtSmoke.spec.adtTypes.map (·.variants.length)) = [2, 2] := rfl + -- Unsafe block smoke test (#1424, Phase 6 Step 6a). -- `unsafe "reason" do` wraps a block of statements;

Previously these hardcoded [] which would fail at compile time for any function body containing Stmt.matchAdt. Medium: Validate that match branch bound variable count matches variant field count in compileMatchAdtBranches. Previously providing too many or too few bindings would silently read unrelated slots or drop fields. P2: mkStorageNamespaceCommand now accepts the resolved Option Nat from parseContractSyntax and uses it when available. Previously it always recomputed from contract name, ignoring storage_namespace "custom.key" overrides. Added rfl assertion in Smoke confirming the exported constant matches the spec value for CustomNamespacedSmoke.

exprReadsStateOrEnv: recurse into adtConstruct args instead of returning true unconditionally, matching exprWritesState behavior and avoiding false rejection of pure functions constructing ADTs - CompileDriver: forward denyUnsafe through both compileSpecsWithOptions and compileModulesWithOptions wrappers so --deny-unsafe works via the public Compiler API - CompileDriverTest: add allowPostInteractionWrites to linkedLibrarySpec's storeHash (external call followed by storage write is a CEI violation that new validation correctly catches) - SourceSemantics proof: handle ADT expr

[PATCH 33/61] fix: update proof infrastructure for adtTypes parameter in compilation pipeline Propagate the new `adtTypes` parameter through all proof files in the IRGeneration chain. The `compileFunctionSpec` and `compileInternalFunction` functions gained an `adtTypes` positional parameter, requiring updates to every call site in the proof files and threading `hnoAdtTypes` hypotheses through the theorem signatures. - SupportedSpec: add `noAdtTypes` field and shortcut theorems - GenericInduction: thread `hnoAdtTypes` hypothesis through induction lemmas - FunctionBody: add `hnoAdtTypes` to body correctness theorems - Function: add `hnoAdtTypes` to function-level theorems, bridge type mismatches with rewrite/subst patterns - Dispatch: insert `[]` for adtTypes at all `compileFunctionSpec` call sites - Contract: insert `[]` for adtTypes, update `compileValidatedCore` rewrites -

no_external_calls validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Internal calls (internalCall, internalCallAssign) have callee bodies that are not visible at single-function validation scope. Previously: 1. `modifies(...)` only checked `stmtWrittenFields` which returns [] for call statements, silently allowing internal calls to write to any field. 2. `no_external_calls` only checked `stmtContainsExternalCall` which only looked at direct external calls, missing external calls inside callees. Added two conservative validation functions: - `stmtHasUntrackableWrites`: flags internal calls for modifies() validation - `stmtMayContainExternalCall`: flags internal calls for no_external_calls External calls (externalCallBind, tryExternalCallBind, ecm) are correctly excluded from the modifies() check — they target other contracts and cannot directly modify the current contract's storage fields.

Since none of the supported statement forms (letVar, assignVar, require, return, stop, mstore, tstore, ite, setStorage, setMapping, etc.) consume events or errors during compilation, these proofs hold for arbitrary event/error lists. This generalization eliminates the need for Contract.lean to rewrite `model.events → []` and `model.errors → []` in the compilation layer, which is the foundational step toward removing `noEvents`/`noErrors` from `SupportedSpecSurface` entirely once Function.lean is similarly generalized.

This fixes the CI build failure on the `build` job. Affected theorems: - exec_compileStmtList_core (StmtListCompileCore, length+1 fuel) - exec_compileStmtList_core_extraFuel (StmtListCompileCore, length+extraFuel+1 fuel) - execStmtList_terminal_core_not_continue (StmtListTerminalCore, no IR) - exec_compileStmtList_terminal_core_sizeOf_extraFuel (StmtListTerminalCore, sizeOf fuel) Each mstore case: compile offset+value, show source continues with updated memory, show IR continues with matching state, recurse on tail.

theorem was hardcoded to work only with empty events, errors, and adtTypes lists, causing type mismatch errors in GenericInduction.lean callers that pass general values. Generalizing the implicit parameters fixes the CI build failure while remaining backwards-compatible with all existing callers (which unify [] with the new implicit params). Also cleans up several linter warnings: unnecessary simpa → simp/exact, and simpa using → simp at for contradiction-based proofs.

Add `stmtMayPersistentlyWrite` — a conservative variant that treats `internalCall` and `internalCallAssign` as potential persistent writes (since their callee bodies are not visible at single-function scope). Use it in the CEI write-after-call check. Note: internal calls do NOT set `seenCall` for CEI purposes — each callee function has its own CEI validation, so treating internal calls as both interactions and writes would produce false positives on contracts like DirectHelperCallSmoke. Also fix a guard_pending state leak in generate_macro_property_tests.py where `#guard_msgs in` / `#check_contract Foo` would incorrectly skip the next `verity_contract` declaration (affected RolesCEISmoke, ModifiesRolesSmoke, UnsafeCEICompliant property test generation).
