Move the materialized index out of salsa into a RootDb-side cache that re-indexes only the files changed by apply_change. A changed file whose ItemTree is unchanged cannot have changed its cross-file-visible definitions, so the other files' indexes stay valid and are reused from the cache; a structural change conservatively falls back to a full rebuild. definition_ranges_for is also memoized per DefId so the incremental re-merge no longer re-projects every definition's origins. common_cells references rebuild after one-file edit: ~3.9s -> ~1.8s.

From 533e763cfea0037e2d197008bd53eed9ea15c765 Mon Sep 17 00:00:00 2001 From: hongjr03 Date: Sun, 16 Aug 2026 15:17:24 +0000 Subject: [PATCH 035/142] refactor(ide): decouple revision cache from Salsa database RootDb was doing two jobs: pure Salsa query engine plus a hand-written revision cache (RevisionProducts/ProductCell) bolted onto its struct. Every clone therefore carried the cache, mixing two incremental systems and forcing the fork-on-apply-change dance for snapshot isolation. Split them: - RootDb is now a pure Salsa database: inputs, parse, HIR, preproc. It holds no request-scoped state and only exposes the salsa query surface plus the pure preproc_affected_files closure. - RevisionCache (was RevisionProducts) is owned by AnalysisHost and forked per change; AnalysisSnapshot carries an Arc to the current fork. - AnalysisContext bundles &RootDb + &RevisionCache and is the type IDE feature functions receive. It derefs to RootDb for salsa queries and exposes the materialized products (semantics, semantic_snapshot_inputs, request_*, reference_index_for_root) as inherent methods. Feature entry points now take &AnalysisContext instead of &RootDb; pure-salsa helpers keep &RootDb or the &dyn db traits. Verified: cargo check --workspace clean, full ide test suite green (209 passed, 11 ignored). --- crates/ide/src/analysis.rs | 338 ++++++++++++- crates/ide/src/analysis_host.rs | 52 +- crates/ide/src/code_action/engine.rs | 4 +- crates/ide/src/code_action/tests.rs | 48 +- crates/ide/src/code_lens.rs | 18 +- crates/ide/src/completion.rs | 3 +- crates/ide/src/completion/context.rs | 5 +- crates/ide/src/completion/engine.rs | 10 +- crates/ide/src/completion/engine/expr.rs | 41 +- .../src/completion/engine/instantiation.rs | 10 +- crates/ide/src/completion/engine/keywords.rs | 6 +- crates/ide/src/completion/engine/member.rs | 17 +- crates/ide/src/completion/engine/named.rs | 19 +- .../ide/src/completion/engine/paren_list.rs | 17 +- crates/ide/src/completion/engine/plan.rs | 6 +- crates/ide/src/completion/engine/port_list.rs | 18 +- crates/ide/src/completion/engine/preproc.rs | 6 +- .../src/completion/engine/sensitivity_list.rs | 10 +- crates/ide/src/completion/engine/tests.rs | 2 +- .../ide/src/completion/engine/typed_filter.rs | 28 +- crates/ide/src/db.rs | 1 - crates/ide/src/db/root_db.rs | 450 +----------------- .../ide/src/db/workspace_symbol_index_db.rs | 3 +- crates/ide/src/definitions.rs | 65 +-- crates/ide/src/document_highlight.rs | 26 +- crates/ide/src/formatting.rs | 24 +- crates/ide/src/goto_declaration.rs | 22 +- crates/ide/src/goto_definition.rs | 17 +- crates/ide/src/hover.rs | 30 +- crates/ide/src/index_benchmarks.rs | 105 ++-- crates/ide/src/lib.rs | 1 + crates/ide/src/manifest.rs | 12 +- crates/ide/src/references.rs | 33 +- crates/ide/src/references/search.rs | 29 +- crates/ide/src/rename.rs | 121 ++--- .../src/{db/caches.rs => revision_cache.rs} | 159 ++++++- crates/ide/src/selection_ranges.rs | 19 +- crates/ide/src/semantic_index.rs | 61 +-- crates/ide/src/semantic_target/tests.rs | 4 +- .../semantic_target/tests/bench_context.rs | 6 +- crates/ide/src/semantic_tokens.rs | 7 +- crates/ide/src/signature_help.rs | 4 +- crates/ide/src/verilog_2005.rs | 16 +- 43 files changed, 978 insertions(+), 895 deletions(-) rename crates/ide/src/{db/caches.rs => revision_cache.rs} (52%) diff --git a/crates/ide/src/analysis.rs b/crates/ide/src/analysis.rs index 560621e4f..d1acb1d19 100644 --- a/crates/ide/src/analysis.rs +++ b/crates/ide/src/analysis.rs @@ -1,13 +1,16 @@ -use std::ops::Range; +use std::{ops::{Deref, Range}, sync::atomic::AtomicBool}; use base_db::{ Cancelled, analysis_snapshot::AnalysisSnapshotId, project::CompilationProfileId, + salsa, source_db::{SourceDb, SourceRootDb}, source_root::{SourceRootId, SourceRootRole}, }; -use preproc_expand::compilation_plan::CompilationPlan; +use hir_def::{def_id::DefId, pathres::ResolutionContext}; +use preproc_expand::{compilation_plan::CompilationPlan, file::HirFileId}; +use rustc_hash::FxHashMap; use triomphe::Arc; use utils::{ cancellation::CancellationToken, @@ -33,9 +36,13 @@ use crate::{ markup::Markup, navigation_target::NavTarget, references::{self, References, ReferencesConfig}, + revision_cache::{ProductCell, ProductPriority, RevisionCache}, rename::{self, RenameConfig, RenameResult}, selection_ranges, - semantic_index::{self, ModuleCallEdge}, + semantic_index::{ + self, FileModuleEdges, FileSemanticIndex, ModuleCallEdge, ModuleEdgeIndex, ReferenceIndex, + SemanticSnapshotInputs, + }, semantic_tokens::{self, SemaToken, SemaTokenConfig}, signature_help::{self, SignatureHelp, SignatureHelpConfig}, source_change::SourceChange, @@ -45,10 +52,328 @@ use crate::{ #[derive(Debug)] pub struct AnalysisSnapshot { pub(crate) db: RootDb, + pub(crate) cache: Arc, pub(crate) snapshot_id: AnalysisSnapshotId, pub(crate) salsa_revision: base_db::salsa::Revision, } +static NEVER_CANCELLED: AtomicBool = AtomicBool::new(false); + +/// Read view of one IDE request: the pure Salsa database plus the +/// revision-scoped workspace cache.

Workspace products (ResolutionContext, indexes) lived in RevisionCache as three dirty sets, a lazy epoch re-check on the request path, and a bag of request_* methods. Replace that with an explicit incrementality module: - Two clocks: salsa revision r and structure epoch s - Three product kinds: structure (ProductCell), file shards, merged indexes - One per-file generation clock instead of three replacing dirty sets - Epoch is decided only in apply_change (Keep | Drop) - Hot-product prewarm survives Drop so structural edits still prewarm - source_semantic_map goes through Salsa, not the store - AnalysisContext API: resolution / file_index / references / module_edges Module layout is incrementality.rs + incrementality/{product_cell,epoch,store,indexes}.rs (no mod.rs).

Instantiation resolve uses that index instead of building ModuleIndex. ResolutionContext pays for unit_scope and the package export map on first import, not on every module-type goto. Mentions keep the preprocessor emitted id so macro-argument tokens can be recovered; lookup falls back to (kind, range) when the extract and request traces disagree. Macro-generated modules prefer Macro owners. --- crates/hir-def/src/db.rs | 1 + crates/hir-def/src/decl_shard.rs | 117 ++++++++++ crates/hir-def/src/decl_shard/extract.rs | 221 ++++++++++++++++++ crates/hir-def/src/design_map.rs | 17 +- crates/hir-def/src/lib.rs | 1 + crates/hir-def/src/pathres.rs | 33 ++- crates/hir-def/src/scope.rs | 19 +- crates/hir-def/src/unit_index.rs | 140 ++++++++--- .../handlers/add_missing_connections.rs | 7 +- .../handlers/add_missing_parameters.rs | 7 +- .../handlers/convert_ordered_connections.rs | 14 +- .../sort_named_instantiation_items.rs | 14 +- crates/ide/src/completion/engine/named.rs | 40 +--- .../ide/src/completion/engine/paren_list.rs | 8 +- crates/ide/src/definitions.rs | 60 +++-- crates/ide/src/diagnostics.rs | 7 +- crates/ide/src/incrementality/indexes.rs | 16 +- crates/ide/src/inlay_hint.rs | 9 +- crates/ide/src/module_resolution.rs | 62 ++--- crates/ide/src/name_index.rs | 5 +- crates/ide/src/name_index/build.rs | 51 +--- crates/ide/src/references/search.rs | 14 +- crates/ide/src/render.rs | 8 +- crates/ide/src/semantic_index.rs | 6 +- crates/ide/src/semantic_index/build.rs | 22 +- crates/ide/src/semantic_tokens.rs | 14 +- crates/ide/src/signature_help.rs | 18 +- 27 files changed, 577 insertions(+), 354 deletions(-) create mode 100644 crates/hir-def/src/decl_shard.rs create mode 100644 crates/hir-def/src/decl_shard/extract.rs diff --git a/crates/hir-def/src/db.rs b/crates/hir-def/src/db.rs index 6c271782b..d37bdb968 100644 --- a/crates/hir-def/src/db.rs +++ b/crates/hir-def/src/db.rs @@ -158,6 +158,7 @@ pub fn set_lru_capacity(db: &mut dyn HirDefDb, capacity: usize) { def_id::set_definition_table_lru_capacity(db, capacity); design_map::set_lru_capacity(db, capacity); item_tree::set_item_tree_lru_capacity(db, capacity); + crate::decl_shard::set_decl_shard_lru_capacity(db, capacity); owner::set_owner_table_lru_capacity(db, capacity); unit_index::set_lru_capacity(db, capacity); scope::set_scope_lru_capacity(db, capacity); diff --git a/crates/hir-def/src/decl_shard.rs b/crates/hir-def/src/decl_shard.rs new file mode 100644 index 000000000..216dd9d1e --- /dev/null +++ b/crates/hir-def/src/decl_shard.rs @@ -0,0 +1,117 @@ +//!

The runs that read a file are already recorded: the include edges the run's parse emitted, plus the manifest its predefines came from. Inverting those costs one memoized slice per root. Sharing the relation with the invalidation model also removes the partial index: there is no longer a step that can half-fail, so the fail-closed PartialPreprocContextIndex error and the two callers that returned empty coverage on it are gone. Drops unit_macro_predefines and unit_macro_contribution, dead since roots stopped injecting predecessor $unit macros. --- crates/preproc-expand/src/context.rs | 11 - crates/preproc-expand/src/db.rs | 59 +---- crates/preproc-expand/src/macro_file.rs | 11 - crates/preproc-expand/src/preproc.rs | 2 +- .../src/preproc/helpers/context.rs | 31 +-- .../src/preproc/tests/include_context.rs | 14 +- .../src/preproc/types/common.rs | 4 - crates/preproc-expand/src/source_db.rs | 3 +- .../preproc-expand/src/source_db/context.rs | 206 ++++-------------- 9 files changed, 59 insertions(+), 282 deletions(-) diff --git a/crates/preproc-expand/src/context.rs b/crates/preproc-expand/src/context.rs index 9664cd361..d344d3fb8 100644 --- a/crates/preproc-expand/src/context.rs +++ b/crates/preproc-expand/src/context.rs @@ -60,17 +60,6 @@ pub fn macro_context_at(db: &dyn PreprocDb, file_id: FileId, offset: TextSize) - pub(crate) fn file_macro_coverage_query(db: &dyn PreprocDb, file_id: FileId) -> Arc { let contexts = db.source_preproc_contexts_for_file(file_id); - if let crate::source_db::SourcePreprocContextStatus::Partial { skipped_models } = - contexts.status - { - tracing::warn!( - ?file_id, - skipped_models, - "macro coverage unavailable because preprocessor contexts are partial" - ); - return Arc::new(MacroCoverage::default()); - } - let mut model_file_ids = vec![file_id]; for model_file_id in &contexts.model_file_ids { if !model_file_ids.contains(model_file_id) { diff --git a/crates/preproc-expand/src/db.rs b/crates/preproc-expand/src/db.rs index 45eb1dbf5..505ed530b 100644 --- a/crates/preproc-expand/src/db.rs +++ b/crates/preproc-expand/src/db.rs @@ -161,7 +161,10 @@ fn source_model(db: &dyn PreprocDb, key: PreprocFileQueryKey) -> Arc PathIdentityIndex { +fn path_file_ids( + db: &dyn PreprocDb, + _key: WorkspacePathIndexKey, +) -> Arc> { let mut index = PathIdentityIndex::default(); for file_id in db.files().iter().copied() { if db.file_is_project_ignored(file_id) { @@ -170,7 +173,7 @@ fn path_file_ids(db: &dyn PreprocDb, _key: WorkspacePathIndexKey) -> PathIdentit let path = compilation_plan::source_buffer_path(db, file_id); index.insert_path(&path, file_id); } - index + Arc::new(index) } pub(crate) fn syntax_tree_options_for_file( @@ -345,52 +348,6 @@ fn dependencies_from_parsed_compilation( Arc::from(dependencies) } -/// `define` directives this file contributes to the compilation-unit scope, -/// reconstructed verbatim so they can be injected as predefines into later -/// roots' standalone parses.

On common_cells that is 287 syscalls per run for zero answers: the canonical fallback never resolved a lookup and no path ever produced a second spelling. It cannot, because every path that crosses an FFI or process boundary left through this index, so it comes back spelled the way we wrote it. The include search probes far more paths than exist -- one nonexistent header is looked up 105 times per run -- so the miss path was the hot one. Lookups are now pure. The workspace index is also shared rather than cloned into every caller. cc_fifo_def hover 326ms -> 244ms cold, 17ms -> 1ms warm; references 180ms -> 150ms cold, 26ms -> 3ms warm; cc_cdc_2phase hover 29ms -> 11ms cold.

Registering only the VFS path made slang open a detached source, so inactive-branch diagnostics for the including file failed closed. Scan include edges once with that slang_path, project include_only and dependencies from the edges, and map returned source buffers through the same table. --- crates/ide/src/diagnostics.rs | 94 +++++ crates/preproc-expand/src/compilation_plan.rs | 352 ++++++++++++------ crates/preproc-expand/src/db.rs | 9 +- crates/preproc-expand/src/preproc/tests.rs | 1 + .../src/preproc/tests/manifest.rs | 31 ++ crates/preproc-expand/src/profile_compiler.rs | 14 +- .../src/source_db/source_mapping.rs | 4 +- crates/utils/src/path_identity.rs | 19 + 8 files changed, 395 insertions(+), 129 deletions(-) diff --git a/crates/ide/src/diagnostics.rs b/crates/ide/src/diagnostics.rs index c5906890e..4e414eb49 100644 --- a/crates/ide/src/diagnostics.rs +++ b/crates/ide/src/diagnostics.rs @@ -877,6 +877,100 @@ mod tests { ); } + fn parent_relative_include_texts() -> (&'static str, &'static str) { + // The include must change the root's inactive set.

Keying by compilation_unit_snapshot fingerprint makes a stale hit a miss, and invalidate patches those files so the cached graph cannot keep the old name. Salsa-tracking generated units off compilation_unit_artifact would force a paid parse of every previously-parsed CU on the next fold, which undoes L0. The overlay stays, but it can no longer be observed stale. AnalysisContext::parse_file may publish a newly paid set; it does not re-decide the epoch. --- crates/design-graph/src/graph.rs | 84 ++++++++++++++++++++------ crates/design-graph/src/lib.rs | 2 +- crates/hir-def/src/unit.rs | 5 +- crates/ide/src/analysis.rs | 6 +- crates/ide/src/generated_units.rs | 35 +++++++---- crates/ide/src/incrementality.rs | 12 +++- crates/ide/src/incrementality/store.rs | 63 ++++++++++++++----- 7 files changed, 154 insertions(+), 53 deletions(-) diff --git a/crates/design-graph/src/graph.rs b/crates/design-graph/src/graph.rs index c476721d0..d9eaec48c 100644 --- a/crates/design-graph/src/graph.rs +++ b/crates/design-graph/src/graph.rs @@ -17,29 +17,68 @@ pub struct UnitMeta { pub header_fingerprint: u64, } -/// Generated units recorded by the IDE from a paid artifact.

One pipeline. Seven request variants each carried their own channel plumbing: the same recv_timeout arms, the same catch_unwind, the same generation lookup, written out seven times. Six of them also called handle_lookup with dummy arguments purely to trigger the rebuild, then threw its answer away and redid the lookup. Reaching the live compilation is one step, so it is one function; a query is a closure the worker runs. Two impossible-state branches that returned NotReady go with it: the generation exists because the caller just built it, and a missing profile is OutsideAnyProfile, which says waiting will not help. Cancellation is not a crash. Salsa unwinds through rebuild whenever the workspace moves on. That stored a poisoned generation and reported Crashed for that revision forever. Cancelled::catch names it and re-raises everything else, so a Rust bug kills the worker instead of hiding. The class-member path is deleted, not kept. SymbolInfo is a superset of ClassMemberInfo, so lookup_class_member had already become dead weight held alive by tests: its Rust, FFI, and C++ sides were all reachable only under cfg(test). Its two tests now drive the shipped offset entry, and t4_gate_numbers loses the or_else that let it pass by opening a private single-file compilation when the shipped path answered nothing. The request path no longer waits out a cold elaboration. The prewarm already held the service handle but never asked it to build, so the first request paid for the whole thing on the keyboard path behind a 60s timeout. Prewarm builds it; the request path gives up after 150ms and the caller keeps the HIR answer. --- crates/ide/src/analysis_host.rs | 7 + crates/ide/src/elaboration.rs | 802 ++++++------------- crates/ide/src/hover.rs | 10 +- crates/ide/src/slang_class.rs | 138 +--- crates/slang-sys/src/compilation.rs | 25 +- crates/slang-sys/src/compilation/ffi.rs | 13 - crates/slang-sys/src/compilation/wrapper.cpp | 74 -- crates/slang-sys/src/compilation/wrapper.h | 6 - 8 files changed, 294 insertions(+), 781 deletions(-) diff --git a/crates/ide/src/analysis_host.rs b/crates/ide/src/analysis_host.rs index 98a809b82..6e977f154 100644 --- a/crates/ide/src/analysis_host.rs +++ b/crates/ide/src/analysis_host.rs @@ -115,6 +115,13 @@ impl AnalysisHost { if !worker_cancel.load(Ordering::Acquire) { let _ = ctx.prewarm_resolution(&worker_cancel); } + // Slang is the last step: it is the slowest and the only one + // a request can do without.

Every consumer threw the contract away. Seven call sites each wrote their own `Ready(Some(x)) else return None`, so Stale, NotReady, Cancelled, Crashed and WorkerGone all arrived at the user as "no such symbol", and the service had no tracing at all. `answered` is now the single way to turn the enum into an Option: routine degradation is debug, a crash or a dead worker is warn. Falling back to HIR is still right; doing it silently was not. Cross-generation SyntaxTree reuse aborted the process. A Compilation constructs its own SourceSession, every tree belongs to the session that parsed it, and add_syntax_tree throws std::logic_error on a foreign one. The one test covering reuse passed only because it reused the first root, which adopts the old session before any parse; wiring the prewarm made every second generation take the path and SIGABRT the suite. Reuse needs a session outliving one generation plus SourceManager::replaceBuffer, which is slang-sys work, so the machinery is gone rather than left as a trap, with the reason recorded where it was. The test now asserts what is actually observable: an unrelated edit does not change another root's answer. --- crates/ide/src/analysis_host.rs | 5 - crates/ide/src/anchor.rs | 9 +- .../code_action/handlers/extract_variable.rs | 10 +- crates/ide/src/completion/engine/member.rs | 43 ++- crates/ide/src/definitions.rs | 7 +- crates/ide/src/elaboration.rs | 254 +++++++----------- crates/ide/src/goto_definition.rs | 7 +- crates/ide/src/hover.rs | 7 +- crates/ide/src/slang_class.rs | 14 +- crates/slang-sys/src/compilation/wrapper.cpp | 25 -- 10 files changed, 145 insertions(+), 236 deletions(-) diff --git a/crates/ide/src/analysis_host.rs b/crates/ide/src/analysis_host.rs index 6e977f154..6afceebdf 100644 --- a/crates/ide/src/analysis_host.rs +++ b/crates/ide/src/analysis_host.rs @@ -160,11 +160,6 @@ impl AnalysisHost { &self.db } - #[cfg(test)] - pub(crate) fn elab(&self) -> &ElaborationService { - &self.elab - } - #[cfg(test)] pub(crate) fn ctx(&self) -> AnalysisContext<'_> { AnalysisContext::new(&self.db, &self.store, &self.elab, self.snapshot_id) diff --git a/crates/ide/src/anchor.rs b/crates/ide/src/anchor.rs index 0f1048acc..84a53cbfb 100644 --- a/crates/ide/src/anchor.rs +++ b/crates/ide/src/anchor.rs @@ -46,16 +46,15 @@ fn project_instance( ctx: &crate::analysis::AnalysisContext<'_>, path: &HierPath, ) -> Option { - use crate::elaboration::ElabResult; - let profiles = { let ids = ctx.db.project_config().profile_ids(); if ids.is_empty() { vec![None] } else { ids.into_iter().map(Some).collect::>() } }; for profile in profiles { - let rows = match ctx.elab.list_instances(ctx.db, ctx.revision, profile) { - ElabResult::Ready(Some(rows)) => rows, - _ => continue, + let Some(rows) = + ctx.elab.list_instances(ctx.db, ctx.revision, profile).answered("instance anchor") + else { + continue; }; let Some(row) = rows.iter().find(|row| row.path == path.as_str()) else { continue; diff --git a/crates/ide/src/code_action/handlers/extract_variable.rs b/crates/ide/src/code_action/handlers/extract_variable.rs index aff6e8beb..58389eaab 100644 --- a/crates/ide/src/code_action/handlers/extract_variable.rs +++ b/crates/ide/src/code_action/handlers/extract_variable.rs @@ -10,7 +10,6 @@ use utils::text_edit::{TextRange, TextSize}; use crate::{ code_action::{CodeActionCollector, CodeActionCtx, CodeActionId, CodeActionKind, line_indent}, - elaboration::ElabResult, slang_class, }; @@ -178,15 +177,14 @@ fn extracted_variable_type(ctx: &CodeActionCtx<'_>, expr: ast::Expression<'_>) - } fn lookup_type_range(ctx: &CodeActionCtx<'_>, range: TextRange) -> Option { - match slang_class::lookup_type_at( + slang_class::lookup_type_at( ctx.analysis(), ctx.file_id(), usize::from(range.start()), usize::from(range.end()), - ) { - ElabResult::Ready(Some(ty)) if !ty.is_empty() && !ty.contains("") => Some(ty), - _ => None, - } + ) + .answered("extract variable") + .filter(|ty| !ty.is_empty() && !ty.contains("")) } fn fresh_variable_name(text: &str, base: &str) -> String { diff --git a/crates/ide/src/completion/engine/member.rs b/crates/ide/src/completion/engine/member.rs index ea4266c57..c98409f76 100644 --- a/crates/ide/src/completion/engine/member.rs +++ b/crates/ide/src/completion/engine/member.rs @@ -23,11 +23,10 @@ pub(super) fn complete_member_access( return Vec::new(); }; if let Some(name) = colon_colon_scope_name(root, position.offset) { - return members_to_candidates( - slang_class::list_scope_members_at(db, position.file_id, &name), - prefix, - ctx, - ); + let members = slang_class::list_scope_members_at(db, position.file_id, &name) + .answered("scope member completion") + .unwrap_or_default(); + return to_candidates(members, prefix, ctx); } let Some(expr) = dot_prefix_expr(root, position.offset) else { @@ -36,33 +35,29 @@ pub(super) fn complete_member_access( let Some(name) = expr_source_text(db, position.file_id, expr) else { return Vec::new(); }; - let named = slang_class::list_scope_members_at(db, position.file_id, &name); - if matches!(&named, crate::elaboration::ElabResult::Ready(Some(members)) if !members.is_empty()) - { - return members_to_candidates(named, prefix, ctx); + // `a.b` where `a` names a scope directly, versus `a` being an expression + // whose type has the members.

It does not. `u0[0]` on an instance array resolves and leaves no selectors; the assert fires when a select could not be applied, as on `bus[0]`. Which case a completion prefix falls into is not knowable before the lookup, so no caller-side check can establish the precondition — the wrapper was catching a programmer-error assert to ask a question it never asked. `Lookup::name` is the API that answers it: it fills a LookupResult, and leftover `selectors` is the same signal without the assert. One helper reads it, and the catch is gone. Two of the four lookup strategies go with this. `find_named_symbol` tried package, root name, class, then a design walk, and no caller could say which had answered; it is now `find_named_scope` with the namespaces named and the walk documented for what it is — the only route to a name inside an instance body when the buffer being completed in does not parse, so there is no expression to resolve instead. `lookup_scoped` had its own copy of the package-then-class half; it calls the shared one now. Tests wait for the prewarm.
