Stack context

The prerequisite #4619 has merged into canary. It provides the shared pure-BAML compiler-test harness used here, so this PR now stands alone against canary; its behavior change is generic function values.

Problem

BAML can infer generic type arguments independently at each direct call, but local function values are monomorphic: a stored callable must have one realized function signature. Previously, the compiler accepted a bare generic function as though the local binding itself remained generic:

function identity<T>(value: T) -> T {
  value
}

function polymorphic_value_examples() -> string[] {
  let copy = identity
  let number = copy(7)
  let word = copy("eight")
  [number.to_string(), word]
}

That implies first-class polymorphism—copy would need to choose a fresh T at each indirect call—but BAML function values carry a concrete realized signature. This PR rejects the unsupported value at the binding instead of allowing the invalid program to proceed.

After this PR

The example above produces one E0001 on identity:

generic function `identity` needs concrete type arguments before it can be stored in `copy`. Specialize it explicitly, for example `identity<int>`. Or write the concrete function type after the binding name: `let copy: (int) -> int throws never = identity`. Calling `identity(...)` directly works only when that call's arguments or expected result determine every type argument

The diagnostic deliberately explains all three relevant choices:

  1. Store one explicit specialization:

    let copy = identity<string>
  2. Give the binding one concrete function type and let that context specialize the function:

    let copy: (string) -> string throws never = identity
  3. Keep independent inference by calling the generic function directly:

    let number = identity(7)
    let word = identity("eight")

If the program truly needs two stored versions, it can bind two explicit specializations:

let copy_int = identity<int>
let copy_string = identity<string>

Behavioral boundaries

Scenario Result Why
identity(7) followed by identity("eight") Compiles Every direct call gets fresh type-argument inference.
let copy = identity E0001 No concrete function type realizes the stored value.
let copy: (string) -> string throws never = identity Compiles The annotation determines every user type parameter.
Passing identity to a concrete callback parameter Compiles The callback type supplies the concrete signature.
Returning or storing identity in a concretely typed field, list, map, branch, optional arm, or default Compiles The surrounding value slot supplies one unambiguous function type.
let f: reflect.AnyFunction = identity E0001 The erased reflection type does not reveal a concrete signature.
Passing identity where the expected type is a union of function types E0001 The compiler does not guess which callable arm was intended.
phantom<T>() -> string in a () -> string context E0001 T does not occur in the function signature, so context cannot infer it.
A later use of copy provides a concrete callback type Still E0001 at the binding Inference does not travel backward and turn an existing local into a generic binding.

Diagnostic edge cases

Multiple generic parameters and function arity

Generic-parameter arity is independent of callable arity:

function project<A, B>(first: A, second: B, fallback: B) -> B {
  second
}

let project_value = project

The diagnostic suggests project<int, int> and derives the concrete annotation (int, int, int) -> int throws never. It never collapses that to the incorrect project<int> or confuses two type parameters with three function inputs.

Bounds

For bounded parameters, the compiler does not manufacture an example that could violate a declared bound. Instead, it names all parameters and shows the signature shape:

choose concrete types for A, B; each type must satisfy its declared bounds
using `(A, B) -> A throws never` as the shape

Generic methods

Method values follow the same rule. A bare box.same reports fixes using box.same<int> and a signature-derived annotation.

Qualified interface projections need additional care. The stored form (Plate<int> as Embosser).emboss cannot accept method type arguments in that syntactic position, so the diagnostic does not recommend the invalid (Plate<int> as Embosser).emboss<int>. It recommends the available concrete annotation instead:

let stamp: (int) -> string throws never =
  (Plate<int> as Embosser).emboss

Callback effects still propagate correctly

Specializing a generic callback must not erase its throws type:

function fail_zero<T>() -> T throws string {
  throw "boom"
}

function foo(cb: () -> string) -> string {
  cb()
}
  • foo(fail_zero) compiles when the caller admits throws string.
  • A throws never caller receives E0096: declared throws is never, but this function may also throw string.
  • A callback parameter explicitly declared throws never rejects fail_zero with a precise function-type mismatch.
  • Merely receiving but not invoking the callback does not propagate its effect.
  • Invoking it under a catch closes the effect before it escapes the wrapper.

Diagnostic assertions

The compiler coverage is pure BAML under:

crates/baml_tests/baml_src/ns_compiler/ns_generics/ns_function_values/

It uses the shared harness from the parent PR:

  • DiagnosticExpectation makes matching policies extensible.
  • ExactDiagnostic checks the complete diagnostic code and complete message.
  • AssertRejected requires exactly one diagnostic.
  • AssertMultiRejected requires the exact count and matches each diagnostic independently in source order.

This prevents a weak assertion where fragments from two different errors accidentally satisfy one expected message. The suite includes two invalid bindings in one file to exercise distinct ordered diagnostics.

The former reflect.call_any runtime test for a bare generic value is removed because that program is now rejected before runtime reflection. Its specific erased-AnyFunction behavior is covered by an exact BAML compiler diagnostic, while the neighboring explicitly instantiated reflection test continues to cover valid runtime dispatch.

One inherited optional-parameter snapshot is refreshed because the parent PR now suppresses that cascaded mismatch diagnostic.

Collapse the two had_expected_type arms into one.

The two match arms are identical except for the literal true/false pattern on had_expected_type and the corresponding literal argument passed to write_generic_function_value_diagnostic. had_expected_type is an ordinary bool field; bind it directly instead of splitting into two arms. This also matches how other arms in this file (for example ConditionAlwaysConstant) bind their bool fields in a single arm.

Add focused unit tests for the branching in write_generic_function_value_diagnostic.

This function has three top-level branches and a four-way branch, but no direct Rust test calls it in isolation. Existing coverage only exercises a subset of the combinations indirectly, through full BAML compilation and snapshot tests in explicit_type_args.rs and the new .baml fixtures. A direct unit test that calls this function (or Display on the enum variant) with each combination of had_expected_type, binding_name, specialization_example, specialization_syntax_available, annotation_example, and function_shape would catch regressions faster and more exhaustively than compiling BAML fixtures for each case.

As per coding guidelines: "**/*.rs: Prefer writing Rust unit tests over integration tests where possible".

…ML#4593)

## Stack context

[BoundaryML#4626](BoundaryML#4626), the independent
deterministic LSP test fix that formed the lower stack layer, is merged
into `canary`. [BoundaryML#4621](BoundaryML#4621),
whose pure-BAML compiler-test harness is used here, is also merged.
Review this PR relative to `canary`.

## Problem

BAML already infers the values that can escape through `throw`. An
explicit `throws` clause is a bound on those inferred values, but
`unknown` was treated as an automatic escape hatch from unused-contract
diagnostics.

That allowed declarations such as these to compile without explaining
the real behavior:

```baml
function DoesNotThrow() -> int throws unknown {
  1
}

function ThrowsOnlyInt() -> int throws unknown {
  throw 1
}
```

The first function does not throw. The second throws only `int`. In both
cases, `throws unknown` is broader than the implementation and hides
useful compiler information.

This precision requirement is specific to `unknown`. An ordinary
explicit bound may remain conservative: `throws A | B | C` is valid when
the function only throws `A | B`.

## After this PR

Both imprecise `unknown` declarations are rejected with E0097.

For a function that does not throw:

```text
`throws unknown` is unnecessary: BAML infers thrown types automatically, and this function does not throw. Remove the declaration; write an explicit `throws` type only to bound what may escape
```

For a function whose inferred thrown type is narrower:

```text
`throws unknown` is imprecise: this function only throws `int`. BAML infers thrown types automatically, so remove the declaration; write `throws int` only to explicitly bound what may escape
```

There are three intended remedies.

1. Let BAML infer the thrown type:

```baml
function ThrowsOnlyInt() -> int {
  throw 1
}
```

2. Keep an explicit, precise bound when the API contract should spell it
out:

```baml
function ThrowsOnlyInt() -> int throws int {
  throw 1
}
```

3. Keep `throws unknown` at a real unknown boundary:

```baml
function Rethrow(value: unknown) -> int throws unknown {
  throw value
}
```

## Behavioral boundaries

| Declaration and implementation | Result |
| --- | --- |
| `throws A \| B \| C`, only `A \| B` escapes | Compiles; ordinary
explicit bounds may be wider than inferred throws |
| `throws unknown`, no escaping throw | E0097: unnecessary |
| `throws unknown`, only `int` escapes | E0097: imprecise |
| `throws string \| unknown`, only `string` escapes | E0097: imprecise |
| `throws unknown`, an `unknown` value escapes directly | Compiles |
| `throws Alias`, where `type Alias = unknown`, and an unknown value
escapes | Compiles |
| `throws unknown`, unknown escapes through a called function | Compiles
|
| `throws string \| unknown`, both string and unknown can escape |
Compiles |
| `throws unknown \| UnusedError`, unknown escapes but `UnusedError`
does not | Compiles with the existing E0097 warning for the unused
concrete member |
| Signature-only interface requirement with `throws unknown` | Remains a
valid contract |

## Diagnostic edge cases

### Concrete superset bounds

The compiler does not require every concrete member of an explicit
`throws` union to appear in the current function body. A bound such as
`throws A | B | C` may intentionally reserve `C` for implementations or
future behavior even when inference currently finds only `A | B`.

`unknown` is different because it admits every value and therefore
erases all useful precision when no unknown-typed value can escape. Only
that unused open member becomes an error.

### Written union surfaces

Finalizing `unknown | SomeError` produces semantic `unknown`, which
would normally erase `SomeError`. The coverage check therefore preserves
the written surface for open unions so that an unused concrete member
still receives the existing warning.

Other contracts continue to use the finalized surface. This avoids false
unused-member warnings for types that reduce through projections or
aliases.

### Aliases and propagated throws

A direct `unknown`, an alias that resolves to `unknown`, and an
`unknown` value propagated through a call all satisfy the contract. The
diagnostic is based on the inferred escaping type, not only on a
syntactic `throw` in the current function.

### Compiler acceptance coverage

The former `ns_fixtures/ns_throws_unknown` corpus fixture has been
replaced with explicit `AssertCompiles` cases. Direct and aliased
unknown bounds, mixed unions, signature-only interface bounds, ordinary
unknown value flow, and callback error translation now state their
expected zero-error behavior at the public compiler boundary.

Iterator functions that either do not throw or fully handle their errors
no longer declare `throws unknown`.

The broader Rust integration-test programs also omit 177 executable
`throws unknown` convenience clauses. Signature-only interface
requirements, callback and function types, pattern checks, and the
dedicated precision tests retain their explicit open contracts.

## Diagnostic assertions

The public behavior is covered in pure BAML at:

```text
crates/baml_tests/baml_src/ns_compiler/ns_throws/ns_unknown_contracts/precision.baml
```

The tests use the shared `reflect.Package._compile` harness from BoundaryML#4621:

- `AssertRejected` and `ExactDiagnostic` lock the exact E0097 code and
message for direct, union, aliased, no-throw, and narrower-throw cases.
- `AssertCompiles` locks concrete superset bounds, accepted unknown
boundaries, transitive propagation, interface signatures, and callback
translation.
- A focused compiler test verifies that an unused concrete member beside
`unknown` remains a warning; successful `_compile` results intentionally
do not expose warnings.

## Validation

- [x] 9 pure-BAML `reflect.Package._compile` contract tests
- [x] Compiler/corpus snapshot coverage updated for the removed fixture
- [x] Mechanical audit of 177 executable test-helper migrations
- [x] Intentional signature and function-type `throws unknown` surfaces
preserved
- [x] Diff and whitespace checks
- [ ] CI after integration-test migration
