refactor(elaborator): identify every declaration by DefId - #1892
Merged
Conversation
An `impl` block was the one declaration the table did not identify, so everything keyed on one — `ImplBlockRef`, `impl_sigs`, `method_sigs`, the impl index — spelled it `(ModuleSource, AstId)` instead. It writes no name, so `name` renders empty and no scope can hold it; a local block is kept out of its block's name map for the same reason. Its methods are members, reached by dispatch like a trait's. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XhVvHrRoLBEabo8aZqSkHG
Every impl index spelled an impl block `(ModuleSource, AstId)` — a pair standing in for the identity the block now has. `TraitImplIndex`, `impl_headers`, `blanket_pack_assocs`, `blanket_param_sources`, `ImplBlockRef`, `BlanketImpl` and `Signatures::impl_sigs` key by the block's `DefId` instead, and a consumer that needed the module reads it off the declaration.

`Signatures` and `ModuleDecls` filed a method, a trait, and an `interface` / `resource` operation under the declaring node. Each is a declaration, so each is keyed by its `DefId` now, and so are the headers and indices that reach them: `ImplMethodHeader`, `MethodSig`, `StaticMethodEntry`, `StaticMethodRef`, `ResourceStaticMethodIndex` and `MethodInfo`. Three lookups that read a declaring node off an identity only to key a map by it lose the round trip. The use→def edge map still names nodes on both sides — navigation recovers a def's module from its id space — so `record_reference_to_decl` reads that node once, at the sink. `trait_env` digested a method header twice, once for a trait's methods and once for an impl's; one producer now answers both. Also fixes two `copied`/`cloned` clippy lints the previous commit introduced.

A parameter default is written in the callee's module and walked from the call site, so a tier order over the *walking* module's names answered with the caller's same-named declaration. The use→def edge then named the caller's function while reify called the callee's, liveness never marked the real one reachable, and the call minted an extern stub for a function the package defines — an ICE. The call's own site was already answered, by the module that wrote it. Read that first. `panic` / `unreachable` reach codegen by name rather than as ordinary callees, so they answer ahead of it.

`function_sigs` was keyed `(ModuleSource, String)`, and seven lookups each spelled their own tier order over it — this module, then the import, then the callee's scope. Three answers to one question, disagreeing exactly where two modules share a spelling. The site was already answered, once, by the module that wrote it. Each lookup now reads it: `free_function_at` / `free_function_sig_at`. The two positions with no site — `builtin::f`, a namespace member's signature — name their module rather than search for one. `CalleeRef` carries the declaration, with the module and name its one constructor reads off the table, so TIR emission needs no table and no rendering is read back. `Rendered` holds what names no declaration in this currency: an effect operation, and the unknown-callee sentinel. Falls out as dead: `symbol_at`, four `CalleeRef` constructors, and the `imported_functions` / `default_scope_module` branches of callee classification.

…gainst `effect_ops` was the last `AstId`-keyed declaration map; the operator path derived an impl's module by walking the receiver's newtype chain comparing renderings, with a by-name lookup behind it. `ArithmeticTraitInfo` carries the block the lookup already matched, so where there is one the module is read off it. The three paths that name no block — an auto-derived `Eq` / `Ord`, and a method reached through a type parameter's bound, whose block monomorphization picks — keep the derivation.

Registering a generic impl's `type X = …` looked its target up by the written name in the impl's module, then scanned every loaded module and took the first match — a build-order pick with no ambiguity check, which WEP 2026-08-12 names as what a derivation may not be. Instrumenting it shows the pick firing: with two modules declaring `Node`, an impl written outside either registers against whichever loaded first. The header names its target at a site of its own, which the writing module answered for — the same read `trait_key` above it already does. The whole-program scan is dropped rather than repaired: the suite passes without it, so nothing consulted what it found. The direct tier is not dead — removing the registration entirely fails the stdlib snapshot. The key stays `AstId`-shaped: its readers arrive through `decl_of_type`, which also answers for monomorphized instances and `BuiltinArray`, neither of which carries a `DefId`.

Six findings from review over the `DefId` re-keying, four of them
regressions this branch introduced.
`panic` / `unreachable` answered ahead of the call's own reference site,
so a module declaring either name of its own lost it: `fn panic(msg) ->
i32` compiled to a `core:rt/panic` call that trapped, with only an
unused-function warning. The site answers first now and the prelude
branch is its fallback, for a synthesised node no walk saw.
Operator dispatch took its module from the matched `impl` block for a
generic block too, but a generic block's post-substitution instance is
materialised in the receiver type's module — the convention
`concrete_impl_module_for` encodes. Only a concrete block names it.
`cm_owner` read the selected method's parent, which is the `impl` block
that declares it rather than a resource, so the spelling fallback it
suppressed never ran and `#[cm("…")]` was dropped. Only a resource's own
method names one.
`function_sigs` assembled by cloning every signature, parameter-default
AST and all, where the per-module digests are shared by `Rc`.
Plus two stale docs: `receiver_site`'s comment had been left above
`callee_site`, and `method_sigs` still said `AstId`.
The local-`impl` identity test now says it covers identity alone:
`TraitEnv::build` walks a module's own items, so nothing a local block
declares is dispatchable yet, which predates this branch.

`of_ast_id(node).expect("every … is a declaration")` had grown to
seventeen sites under eight wordings, all asking the one question
`DefTable::def_at` now answers — and its panic names the node, which
none of the eight did.
`CalleeRef::declared(resolutions.defs(), …)` likewise: `callee_of` takes
the declaration and `callee_in_module` the two-step behind it, so no
call site threads the table to build a callee.
The rest is comments the code says for itself, and one duplicated
lookup: `effect_ops` re-derived the owner two lines under the binding
that already held it.

The pipeline table merged everything from analyze to TIR emission into one `Annotate | TIR + facts` row, so nothing pointed at resolve, liveness or reify, and `TirModule` was attributed to annotate.

`X.tysys.resolutions.defs().def_at(id)` stood at ten call sites across four receivers; `TypeParamScope` derefs to the walker, so one method serves them all. An `Arc::clone` guarded a borrow that was never taken: `cm_owner`'s `or_else` reads `&self` like everything around it. The fixtures said in a header what their own `test` names already said, and each sub-module re-explained the entry module's half.

`decl_in_module` joins the sanctioned list: it is `lookup_in_module` read back as an identity, for the qualified positions no reference site answers. `impl_target_decl_key` was listed as going once the impl index carried `DefId`s. It carries them now, and the entry survives — a dispatch that matched a concrete block reads the module off it, but an auto-derived `Eq` / `Ord` and a bound-reached method name no block to read. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XhVvHrRoLBEabo8aZqSkHG
`type_params.is_empty()` stood at three sites asking it — the module
index's `concrete_only` filter, method lookup's `skip_filter`, and
operator dispatch — so `ImplHeader::is_concrete` answers instead.
The WEP entry this branch added said `decl_in_module` served "the two
qualified positions". It serves four, and one of them — a default
expression's own module — is not qualified. Its neighbour narrated the
change ("now carries `DefId`s") where a WEP states what stands.

The gap named one registry built before bodies are walked. There are two, and only `TraitEnv` yields to a body walk — `Signatures` is frozen between the declaration pass and that walk, while a local `impl`'s target interns its `TypeId` inside it. Recorded with what a first attempt hits: the orphan rule reads a function-local target as foreign, and indexing `TraitEnv` alone turns the diagnostic into a panic. The walker slim-down drops a field count that has since moved. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XhVvHrRoLBEabo8aZqSkHG

…claration
A static call resolved its impl blocks from the receiver's written spelling.
Under `use { Meters as M }`, `M::from(3)` compared the impl header's head
(`Meters`) against the call's spelling (`M`), matched nothing, and reached WIR
build with an unresolved call. Where the spelling was the declared name that
the caller never imported, the derived key indexed nothing at all.
`locate_static_method_impl` and `conversion_impl_survey` now compare against
the target declaration's own name, and take the resolved `ImplTargetKey` from
the paths that already hold one: `resolve_static_method_call` off the receiver
type, and the newtype base in `resolve_static_method_call_from_qualified`.

…eiver An impl block writes its target under whatever name its own module imported, so a header's head is neither the declaration's name nor a call site's: `impl From<Instant> for ClockInstant` in core:temporal targets wasi:clocks' `Instant`. Comparing the head against the declared name dropped such an impl and left the mangled call unresolved at WIR build. The head is canonicalised in the impl's own module first, as the argument-type match beside it already does.

- Around line 3304-3306: Update the target-head computation around
get_type_name_static and import_original_name so names found in
header.type_params retain their binder spelling; only canonicalize non-binder
heads. Ensure both lookup paths preserve impl<T> ... for T when an alias such as
Thing as T is in scope, and add a shadowing fixture covering this case.
In `@wado-compiler/tests/fixtures/aliased_impl_head.wado`:
- Around line 16-19: Add a trailing __DATA__ JSON expectation section to the
fixture after the test block, using the field names and structure defined by the
serde expectation structs in tests/e2e.rs so the harness records this conversion
regression.

A block's own type parameter shadows any import, so a head its `type_params` bind is already a declaration name and must not be resolved through the module's aliases. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XhVvHrRoLBEabo8aZqSkHG
The five copies of "the caller's resolved key, else the written name" become one helper, and the receiver-target step folds into the impl-key lookup it only ever fed. Drops the `_keyed` suffix where no unkeyed sibling remains. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XhVvHrRoLBEabo8aZqSkHG

elaborate, a declaration is aDefId. A site — an expression, a call, a reference — stays anAstId, which is whatResolutionsis keyed by and what a binder gets. Every table that files a declaration keys by identity.DefTableidentifiesimplblocksAn
implblock writes no name, so no symbol table row named it and it had no identity. It gets one (DefKind::Impl), and its methods become members under it, reached by dispatch like a trait's. The block renders an empty name because it writes none, which is also what keeps it out of every scope; a local block is excluded from its block's name map for the same reason.The tables that follow

ItsRenderedcase is what genuinely names no declaration: an effect operation, whose module is the namespace WIR keys on, and the unknown-callee sentinel.DefTable::def_atanswers "the declaration at this node" once, andElaborator::{def_at, free_function_at, free_function_sig_at, decl_in_module, callee_of, callee_in_module, record_reference_to_decl}are the walker's reads of it.Three defects the identities close
A bare call is answered by its own reference site. Seven lookups each spelled a tier order over the walking module's names — this module, then its imports, then the callee's scope. A parameter default is written in the callee's module and walked from the call site, so a caller declaring the same spelling took the answer: the use→def edge went to the caller's function while reify emitted a call to the callee's, and the package minted an extern stub for a function it defines. Fixture:
