Current state (analyst, evidence-anchored) + +Per-file-only "Hybrid LSP" mirroring php_lsp/go_lsp. Entry cbm_run_perl_lsp (internal/cbm/lsp/perl_lsp.c:1638, wired at internal/cbm/cbm.c:1377) builds a per-file CBMTypeRegistry: stdlib seed (generated/perl_stdlib_data.c:65 cbm_perl_stdlib_register — only 29 perlfunc builtins + 5 modules/~25 subs, 140 lines vs go's 30k), file-local Function/Method defs (perl_lsp.c:1654), per-package types with @ISA parents as embedded_types (perl_register_packages:1408) and method tables (perl_attach_methods:1558, top-level + block-scoped packages only). Two-pass walk (perl_lsp_process_file:1358): PASS1 (perl_pass1_scan:1325) collects package_statement context (process_package_decl:1118 incl. SUPER:: parent), use parent/base + @ISA (perl_collect_use_statement:1230, perl_collect_isa_assignment:1270 incl. Pkg::ISA and flattened-paren RHS), Exporter qw() imports (perl_collect_qw_imports:1145, dotted-QN targets); PASS2 resolves calls: bare/imported/Pkg::sub static calls with last-"::" split (perl_resolve_function_call:789), method calls via typed receiver + @ISA BFS (perl_resolve_method_call:844, perl_lookup_method:317), SUPER:: via first ISA parent (859), \&coderef references (perl_resolve_direct_coderef_arguments:718) and coderef VALUE usages (757). Typing: bless literal/__PACKAGE__/ref($class)||$class (perl_eval_bless:388, conf 0.95/0.75), Class->new (perl_eval_new_type:525), scalar scope bindings via cbm_scope (perl_process_assignment:909), invocant only via `my $self = shift`/`$_[0]` first-match idiom (perl_infer_self_type:1028). Zero-edge guarantee throughout; walk-depth cap 512; O(1)-child collection for wide nodes (perl_collect_children:175). Extraction side: lang_specs.c:611-620 gives Perl only subroutine_declaration_statement as func type, EMPTY class/field types (no Class nodes, no base_classes → zero INHERITS edges; sub QNs are module_qn.subname, package not woven in); callee names are bare identifiers (extract_calls.c:490-504 perl_is_identifier_callee); imports = top-level use_statement text only (extract_imports.c:2999 parse_generic_imports); perl vars extracted (extract_defs.c:5747). Pipeline: perl method calls + builtin-named calls with weak strategies are deliberately suppressed (registry.c:414 cbm_perl_suppress_generic_match, pass_calls.c:604, pass_parallel.c:2473), so without cross-file LSP most cross-file Perl edges are dropped; cbm_run_perl_lsp_cross is DECLARED (perl_lsp.h:114) but has no implementation and no case in cbm_pxc_run_one (src/pipeline/pass_lsp_cross.c:1156 switch; language gate at 881-893 lacks PERL). Vendored grammar (parser.c ts_symbol_names, no node-types.json) already exposes unused Corinna nodes (class_statement, role_statement, method_declaration_statement, field, class_phaser_statement/ADJUST), signatures (signature, mandatory/optional/named/slurpy_parameter), attribute/attribute_name/attribute_value, require_expression, coderef_call_expression, anonymous_method_expression; fields name/attributes/initialiser/version/variables. .t/.psgi/.cgi are not mapped to Perl (src/discover/language.c:218 only .pl/.pm); cbm_is_test_file (internal/cbm/helpers.c:393) has no PERL case and no t//xt/ rule; no Perl route detection can fire (service_patterns.c:473 suffixes need ".get"/"::get", Perl callees are bare "get"). + +Test coverage: Suite "perl_lsp" (tests/test_perl_lsp.c, 587 lines, registered tests/test_main.c:1098; run: make -f Makefile.cbm test-focused TEST_SUITES=perl_lsp). 17 tests, all inline-source via cbm_extract_file(...,"test","main.pl"): bless-assignment dispatch, Foo->new constructor typing, Foo::bar() and multi-level Acme::Widget::render() static calls, $self=shift dispatch, @ISA / use parent / use base inheritance, Exporter qw import, Scalar::Util stdlib import, require fallback, SUPER:: dispatch + no-parent negative, unresolved-receiver zero-edge negative, and 3 site-dedup regressions. No fixture files exist under tests/fixtures for Perl. Extraction-level Perl coverage elsewhere: tests/test_extraction.c:1116,4934-4983 (subs/vars), test_grammar_regression.c:98, test_grammar_imports.c:88 (use_statement), test_language.c:187-191 (.pl/.pm mapping), test_stack_overflow.c:612. Nothing covers signatures, Corinna, Moose, routes, .t tests, require, or cross-file resolution. +

Implement the declared stub exactly on the php template: parse (or reuse cached_tree), cbm_registry_init + cbm_perl_stdlib_register, register the caller-supplied CBMLSPDef[] as CBMRegisteredFuncs (receiver_type from def->receiver_type when present), seed ctx use-map from import_names/import_qns, cbm_registry_finalize_into a scratch idx_arena, then perl_lsp_process_file. Two Perl-specific additions: (a) build the import map from each file's `use Foo::Bar qw(...)` rows in result->imports — target QN = resolved module QN + '.' + symbol, reusing perl_pkg_to_dot and the pipeline module-def index filtering (per the cbm_pxc_run_one_filtered comment, never the full def list); (b) a package→module map: for a bareword receiver `Foo::Bar->m` or static `Foo::Bar::sub()`, when the local registry has no type `Foo::Bar`, map the package to the module whose rel path ends Foo/Bar.pm (convention lookup over the module-def index, also stripping a leading lib/ the way pass_lsp_cross.c:305 strips java/kotlin roots) and register that module's Function defs as the package's method table. Keeps the zero-edge guarantee: no mapping → no edge. + +**对拍A correction (binding):** Implement on the php template with: (a) a prerequisite commit making Perl use/require module paths resolve in pass_pkgmap (::→/ plus lib/ root attempt) so IMPORTS edges, the import map, and the def filter all populate; (b) a seeded-imports floor in PerlLSPContext so process_file's PASS-1 reset preserves caller-supplied mappings; (c) qw-symbol targets composed from the resolved module QN in the import map, falling back to nothing (zero-edge) when the module is unresolved; (d) package→module mapping derived from filtered defs' def_module_qn tails (path ends Foo/Bar.pm, lib/ stripped) inside the resolver, registering that module's Function defs as the package's method table; (e) wiring = CBM_LANG_PERL in cbm_pxc_has_cross_lsp + a case in cbm_pxc_run_one. Keep the proposed direct-call unit tests; add one asserting a file with an unresolvable use emits nothing. + +**对拍B correction (binding):** Implement as proposed EXCEPT the import-map sourcing: Perl rows in result->imports are raw top-level use_statement text from the direct-children-only generic parser (extract_imports.c:954-976) — the wrong substrate for symbol maps. Instead let perl_lsp_process_file's own PASS 1 (perl_lsp.c:1362-1369, qw collection :1145-1172) re-collect `use Module qw(...)` from the AST for free, and resolve each Module::Name against the module-def index (rel path ends Foo/Bar.pm, stripping leading lib/ and t/lib/) to rewrite import targets to the defs' real path-based QNs (test.lib.Foo.Bar.sym); use result->imports only to seed the package→module map for bareword receivers. Everything else (php mirror, per-file scratch registry, zero-edge guarantee, filtered defs) stands. Pair with the missed perl-exporter-export-model so `use Foo;` with NO qw() list — the most common style — resolves Foo's @EXPORT defaults; without it this proposal only covers explicit import lists. + +Test plan: tests/test_perl_lsp.c (suite perl_lsp): call cbm_run_perl_lsp_cross directly with a hand-built CBMLSPDef[] — e.g. defs {qualified_name:"test.lib.My.Util.helper", short_name:"helper", label:"Function"}, imports {"helper"→"test.lib.My.Util.helper"}, source "use My::Util qw(helper);\nsub run { helper(); }" asserting an edge main.run→My.Util.helper; a Foo::Bar->new cross-file test with defs {"test.lib.Foo.Bar.new", receiver-less} + module-map fixture; and a negative: unknown package emits nothing. + +### perl-corinna-class (P0/M, wave 2) + +**Extract and resolve Corinna OO (class/method/field/ADJUST/role, :isa) — Perl 5.38's headline feature** + +Files: internal/cbm/lang_specs.c (perl_func_types: add "method_declaration_statement"; new perl_class_types[] = {"class_statement", "role_statement"} replacing empty_types at :1860); internal/cbm/extract_defs.c (Perl branch: class name via field `name`, base_classes from the `attributes` field's attribute nodes where attribute_name=="isa" → attribute_value; `field` nodes inside a class body → Property defs with parent_class); internal/cbm/lsp/perl_lsp.c (perl_pass1_scan_inner:1333 + perl_resolve_calls_in_node_inner:946: treat class_statement/role_statement like package_statement for current-package context and record :isa via perl_add_isa; perl_attach_methods:1558: descend class_statement bodies like block packages; process_subroutine:1086: for method_declaration_statement bind implicit $self — and $class for :common — to the enclosing class type before walking the body) + +Scope: The grammar already parses `class Foo :isa(Base) { field $x :param; method m { $self->n() } ADJUST {...} }` (verified sym_class_statement, sym_field, sym_method_declaration_statement, sym_class_phaser_statement in vendored parser.c), but today a Corinna file yields ZERO defs for methods (method_declaration_statement is not a func type) and zero classes. Adding the node kinds gives Class/Method defs with parent_class via the generic extractor (Method promotion path extract_defs.c:3755) and INHERITS edges for free via base_classes (pass_parallel.c:2779). Resolver work makes $self->m() inside methods and Obj->new across classes dispatch, including inherited methods through :isa. ADJUST blocks need only be walked for calls (caller = enclosing class's synthetic scope or skipped—zero-edge). Ensure perl_attach_methods composes the SAME QN the extractor emits for class methods (module_qn.Class.method once class_node_types exist — helpers.c cbm_enclosing_func_qn weaves class scopes) or dispatch lookups will miss. + +**对拍A correction (binding):** Same scope minus statement-form classes (block and postfix-block only for v1; document the exclusion), with the extraction half reduced to lang_specs.c changes (perl_func_types += method_declaration_statement; new perl_class_types = {class_statement, role_statement}; perl field types += field) riding the existing generic class machinery, plus the resolver half exactly as proposed (class_statement as package context in PASS1/PASS2, :isa via perl_add_isa, implicit $self binding in process_subroutine for method_declaration_statement, perl_attach_methods QN weaving matched to push_method_def). Add a grammar-shape probe test before the dispatch tests. + +**对拍B correction (binding):** Three corrections: (1) Perl 5.38 shipped NO roles — role_statement in the grammar anticipates Object::Pad/future Corinna; parse-tolerate it but do not present it as a 5.38 core feature or gate tests on it; likewise field :reader is 5.40+, synthesize nothing for it. (2) Pin the extraction route before writing code: walk_defs' class path both calls extract_class_def AND pushes body children with class context (extract_defs.c:7880-7885), while Perl is excluded from the free-function QN re-scope gate (:3674-3679) — verify exactly one of extract_class_methods or a Pony-style ancestor promotion (:3755-3772) emits each Method def (no duplicates), and that its QN (module.Class.method) is exactly what the updated perl_attach_methods/process_subroutine (:1092-1099) compose for class-scoped methods, keeping plain subs at module.sub per the documented contract (test_perl_lsp.c:20-26). (3) Also set enclosing_parent_qn from :isa so SUPER:: works inside methods, bind $class instead of $self for :common methods, and walk field initializers + ADJUST blocks for calls. + +Test plan: tests/test_perl_lsp.c: TEST(perllsp_corinna_method_dispatch) with source "use v5.38;\nuse experimental 'class';\nclass Animal { method speak { return 1 } }\nclass Dog :isa(Animal) { method fetch { $self->speak() } }" asserting fetch→speak (inherited) edge; TEST for `my $d = Dog->new; $d->fetch;` from a main sub. tests/test_extraction.c: assert class Dog produces a Class def with base_classes[0]=="Animal", a Method def fetch, and field $tricks a Property def. + +### perl-invocant-signatures (P0/S, wave 1) + +**Bind the invocant from sub signatures and `my ($self, ...) = @_;` list assignment** + +Files: internal/cbm/lsp/perl_lsp.c (perl_infer_self_type:1028 and process_subroutine:1086) + +Scope: Modern Perl (signatures stable since 5.36) writes `sub render ($self, $depth) { $self->draw() }`; classic code overwhelmingly writes `my ($self, $x) = @_;`. Neither binds $self today, so every method body in such files loses all $self->m() edges. Two additions: (1) in process_subroutine, before walking the body, find the `signature` child (perl_first_child_of_type(node, "signature")); if its first named parameter (mandatory_parameter) text is `$self` or `$class`, cbm_scope_bind it to the enclosing package type (name-gated to avoid typing plain functions' first params). (2) in perl_infer_self_type, handle the list form: LHS variable_declaration whose target is a parenthesized/list of scalars (grammar field `variables` / list child) with RHS text `@_` — bind the FIRST scalar if named $self/$class. Both reuse the existing pkg = enclosing_package_qn logic and PERL_CONF idioms; ~80 LOC. + +Test plan: tests/test_perl_lsp.c: TEST(perllsp_signature_self_dispatch) — "use feature 'signatures';\npackage Widget;\nsub render ($self, $d) { $self->draw($d); }\nsub draw ($self, $d) { return $d; }" asserts render→draw; TEST(perllsp_list_unpack_self) — "sub render { my ($self, $x) = @_; $self->draw(); }" asserts render→draw; negative: `sub util ($cfg) { $cfg->go() }` emits nothing (verified syntax with perl -c under feature 'signatures'). + +### perl-moose-attrs (P1/M, wave 2) + +**Moose/Moo/Object::Pad: has/extends/with → synthetic accessors, attribute types, inheritance** + +Files: internal/cbm/lsp/perl_lsp.c (perl_pass1_scan_inner:1333 — recognize top-level function_call/ambiguous_function_call with callee has/extends/with when ctx flag moose_mode is set by perl_collect_use_statement:1230 seeing use Moose|Moo|Mouse|Object::Pad|Class::Accessor; new per-package attr table {attr_name → isa CBMType}; perl_lookup_method:317 — accessor fallback; perl_eval_method_call_type:588 — return attr isa type for accessor calls); internal/cbm/extract_defs.c (optional: synthetic Method defs named after each has attr, parent the enclosing package, so accessor edges have graph nodes) + +Scope: Moose-style classes are the largest real-world Perl OO population. Handle three keywords in PASS 1: `extends 'Base';`/`with 'Role';` → perl_add_isa(current_pkg, name) (string/qw args via the existing perl_collect_parents:1179); `has 'name' => (is=>..., isa=>'Class::Name', handles=>...)` → record (pkg, attr, isa-type). Resolution: (a) $self->name() where name is an attr resolves — emit an edge only if a synthetic def node exists (extraction half), otherwise stay silent but STILL return the isa type from perl_eval_method_call_type so CHAINED dispatch works: `$self->engine->start()` types $self->engine as Engine and resolves start() — this typing half alone recovers many edges with zero false-edge risk. Parse isa strings through perl_resolve_package_name; ignore parameterized types (ArrayRef[...]) → unknown. Object::Pad `field $x :param;`/ `has $x;` inside class blocks reuses the Corinna field path. + +**对拍B correction (binding):** Scope corrections: (a) track moose_mode PER PACKAGE, not per file — multi-package files with one Moose package would otherwise treat foreign `has` calls as attrs; (b) handle `has ['a','b'] => (...)` arrayref multi-attr and `has '+attr'` override (strip the +, do not mint a new attr); (c) record handles => [qw(...)] / {local=>remote} delegate names at least for typing of delegated calls, or explicitly defer them; (d) Object::Pad's `has $x;` takes a VARIABLE argument, not a string — exclude it from the Moose string-form matcher (its class-block field/has forms ride the Corinna path); (e) `extends` REPLACES @ISA rather than appending — append is an acceptable approximation for edges but note it; `with` mapped to perl_add_isa is a sound flattening approximation for role method lookup. + +Test plan: tests/test_perl_lsp.c: TEST(perllsp_moose_extends) — "package Base; sub greet {1}\npackage Child; use Moose; extends 'Base';\nsub run { my $self = shift; $self->greet(); }" asserts run→greet; TEST(perllsp_moose_attr_chain) — "package Engine; sub start {1}\npackage Car; use Moo; has engine => (is=>'ro', isa=>'Engine');\nsub go { my $self=shift; $self->engine->start(); }" asserts go→start; negative: `has` in a non-Moose file resolves nothing. + +### perl-stdlib-538 (P1/M, wave 2) + +**Expand perl_stdlib_data.c toward the 5.38 core: full perlfunc builtins, top core modules with real export lists, curated OO types** + +Files: internal/cbm/lsp/generated/perl_stdlib_data.c (regenerate); scripts/gen-perl-stdlib.pl (new, dev-time only, mirroring scripts/gen-py-stdlib.py; runs Module::CoreList/%EXPORT introspection offline); src/pipeline/registry.c:380 (keep PERL_BUILTINS in lockstep — single source comment) + +Scope: The 140-line table covers 29 builtins and 5 modules; the pipeline's own suppression list (registry.c PERL_BUILTINS, ~90 names) is richer than the LSP's, so suppression and resolution disagree. Generate: (1) the full perlfunc builtin set (say, sprintf variants, sort/keys/each already there — add ~60: lc/uc/ucfirst/index/rindex/abs/int/hex/oct/ord/chr/pack/unpack/sleep/exit/eval/system/exec/localtime/gmtime/time/mkdir/opendir/readdir/unlink/rename/stat/binmode/seek/tell/eof/wantarray/local/tie/…) as REG_BUILTIN rows; (2) ~40 core modules with their actual @EXPORT/@EXPORT_OK subs as REG_FUNC rows — List::Util (sum0/uniq/any/all/none/pairs/…), Scalar::Util (looks_like_number/refaddr/dualvar/readonly/…), File::Basename, File::Path, File::Copy, File::Temp, File::Spec (class methods), Getopt::Long, Cwd, Time::HiRes, Time::Piece, Sys::Hostname, Digest::MD5/SHA, MIME::Base64, Encode, JSON::PP, POSIX (expanded), Fcntl, Socket, Term::ANSIColor, Pod::Usage, Exporter, Carp (cluck/confess present), constant, overload; (3) curated OO types via CBMRegisteredType + receiver-keyed cbm_registry_add_method (the perl_lookup_method:343 direct path already consumes these): DBI (connect→DBI::db), DBI::db (prepare→DBI::st, do, selectall_arrayref…), DBI::st (execute/fetchrow_hashref/…), IO::File/IO::Handle, File::Temp, Time::Piece, LWP::UserAgent (get/post→HTTP::Response) — giving typed chains like $dbh->prepare(...)->execute(). + +**对拍B correction (binding):** Use the receiver_type-on-CBMRegisteredFunc registration pattern (not the nonexistent cbm_registry_add_method); add Test::More/Test2::V0 exports (ok is isnt like cmp_ok is_deeply subtest plan done_testing diag note pass fail skip BAIL_OUT) to THIS table since perl-test-ecosystem depends on them; add `say` and the other suppression-list names so the two lists converge (keep the single-source comment); keep dotted-module QNs (Foo.Bar.func) to match perl_collect_qw_imports (perl_lsp.c:1160-1169); POSIX exports nearly everything by default — model the common subset and note the limitation. + +Test plan: tests/test_perl_lsp.c: TEST(perllsp_stdlib_file_basename) — "use File::Basename qw(basename);\nsub f { basename('/x'); }" resolves to File.Basename.basename (mirror existing perllsp_cpan_exported_function at :~330); TEST(perllsp_dbi_chain) — "use DBI;\nsub q { my $dbh = DBI->connect('dsn'); my $sth = $dbh->prepare('sql'); $sth->execute(); }" asserts typed resolution reaches DBI.st.execute (registry method, no graph node — assert via resolved_calls callee_qn text). + +### perl-web-routes (P1/M, wave 3) + +**Extract HTTP routes for Mojolicious(::Lite) and Dancer2** + +Files: internal/cbm/service_patterns.c (new cbm_service_pattern_perl_route_method(callee, is_method) beside cbm_service_pattern_route_method:847); src/pipeline/pass_calls.c (empty-resolution route fallback ~:571-575 — call the perl matcher when lang==CBM_LANG_PERL); src/pipeline/pass_parallel.c (~:2473 parallel twin — the two call sites must stay in lockstep per the guard comments) + +Scope: Perl route registrations never mint Route nodes: `$r->get('/users' => sub {...})` and Dancer2/Mojolicious::Lite `get '/users' => sub {...}` extract callee_name "get" (bare, extract_calls.c:495-504), which can never match the ".get"/"::get" suffix table (service_patterns.c:473), even though first_string_arg ("/users") and second_arg_name (the sub) are already captured generically (extract_calls.c:3710-3733). Add a Perl-gated matcher: bare names get/post/put/patch/del/delete/options/any/websocket/under (Mojolicious + Dancer2 DSL; `del` is Dancer2's spelling) → method mapping, accepted for BOTH function-call and method-call forms, required first_string_arg[0]=='/'; route handler attribution via the existing second_arg_name→anonymous-sub linkage in handle_route_registration (pass_calls.c:208). This reuses the entire existing Route-node machinery (pass_route_nodes.c) — only the recognition predicate is new.

A small Perl-specific collector walks top-level expression_statements (plus one level into BEGIN phaser_statement blocks) for require_expression, extracting the `module` bareword or a string literal path (Foo/Bar.pm → Foo::Bar). This feeds the existing IMPORTS resolution (::→/ conversion already in pass_pkgmap.c:2047 Strategy 4) and the cross-file import map (proposal perl-cross-file-lsp).

(2) WIDEN the scan instead: the most common require patterns are conditional — `if (...) { require Foo; }` and the `eval { require JSON::XS; 1 } or ...` fallback idiom — so a top-level-plus-BEGIN scan misses them; since require_expression is a named node, walk the whole tree for it (cheap) and emit rows only for literal barewords and 'Foo/Bar.pm' string operands, skipping variables. + +Test plan: tests/test_grammar_imports.c (perl entry at :88): extend the fixture with "require My::Loader;\nrequire 'Legacy/Helper.pm';" asserting two additional import rows My::Loader and Legacy::Helper; tests/test_perl_lsp.c negative stays green (require fallback test at :580 already covers call-side behavior). + +### perl-package-class-nodes (P2/M, wave 4) + +**Emit Class nodes for packages and INHERITS edges from @ISA/use parent/use base** + +Files: internal/cbm/extract_defs.c (Perl handler: package_statement → Class-labeled def named by field `name` (::-form preserved), spanning to the next package statement or block end; populate base_classes[] by scanning the same top-level region for use parent/base and @ISA assignments — reuse the recognition shapes from perl_lsp.c:1230/1270 as a shared helper or duplicate the small matcher); internal/cbm/lang_specs.c (keep class_node_types empty to avoid QN re-weaving of existing sub defs — the handler is explicit, not spec-driven) + +Scope: An AI agent asking 'what inherits from what' gets NOTHING for classic Perl today: inheritance lives only inside the per-file resolver (ctx->isa_* tables) and never reaches the graph, and packages have no nodes to hang DEFINES/INHERITS on. Emitting one Class def per package_statement plus base_classes lets the generic pipeline mint INHERITS edges (pass_parallel.c:2779) with zero new edge machinery. Deliberately does NOT add package_statement to class_node_types: that would re-scope every sub QN to module.Package.sub and break the documented QN contract (perl_lsp.c header, test_perl_lsp.c substring asserts) — instead the Class def is additive and sub defs keep module-level QNs, with parent_class optionally set on subs between a package statement and the next (enabling DEFINES_METHOD without QN changes). + +Test plan: tests/test_extraction_inheritance.c (or test_extraction.c): source "package Base;\nsub speak {1}\npackage Derived;\nuse parent -norequire, 'Base';\nsub new { bless {}, shift }" asserts a Class def 'Derived' with base_classes[0]=="Base" and a Class def 'Base'; whole perl_lsp suite must stay green (QN contract untouched). + +### perl-dynamic-dispatch (P2/S, wave 4) + +**AUTOLOAD fallback and ->can('name') reference edges** + +Files: internal/cbm/lsp/perl_lsp.c (perl_lookup_method:317 — after the @ISA walk fails, re-walk for a method literally named AUTOLOAD and return it under a distinct strategy; perl_resolve_method_call:844 — emit that edge with confidence PERL_CONF_INFERRED and strategy "perl_autoload"; new branch in perl_resolve_method_call for method name "can"/"isa" with a string-literal first argument: resolve the NAMED method on the receiver's type and emit a CBM_RESOLVED_CALL_REFERENCE like perl_emit_reference:646) + +Scope: Legacy OO (LWP, SOAP::Lite-era code, accessor generators) routes unknown methods through sub AUTOLOAD; today a typed receiver whose method isn't in the chain emits nothing (perl_resolve_method_call:900 comment), hiding the real dispatch target that IS indexed. Since the receiver type is already resolved and AUTOLOAD is found via the existing chain walk, this stays inside the zero-edge guarantee (edge only to an indexed sub, lower confidence, distinct strategy so consumers can filter). Second half: `$obj->can('render')`/`__PACKAGE__->can('render')` with a string literal resolves 'render' through perl_lookup_method on the receiver type and emits a CALL_REFERENCE (same kind the \&coderef path uses), capturing the ubiquitous capability-check-then-call pattern without fabricating an invocation edge. + +**对拍B correction (binding):** (a) Restrict the string-literal reference branch to `can` only: $obj->isa('Name') takes a PACKAGE name, not a method name — resolving 'the named method on the receiver' for isa would fabricate references (at most map isa/DOES to nothing or a type reference). (b) Keep the DESTROY gate but fix its rationale: Perl DOES route DESTROY through AUTOLOAD when no DESTROY is defined (that is exactly why the empty `sub DESTROY {}` idiom exists); the gate is justified as edge-noise policy (GC-driven DESTROY has no call site), not as a language rule. (c) Also exclude other implicitly-dispatched/universal names from AUTOLOAD fallback: import/unimport/VERSION/can/isa/DOES. __PACKAGE__->can(...) already works via the bareword-invocant path (perl_resolve_package_name:268-278). + +Test plan: tests/test_perl_lsp.c: TEST(perllsp_autoload_fallback) — "package Proxy;\nsub new { bless {}, shift }\nsub AUTOLOAD { my $self = shift; }\npackage main;\nsub run { my $p = Proxy->new; $p->whatever(); }" asserts run→AUTOLOAD with strategy perl_autoload; TEST(perllsp_can_reference) — "$self->can('draw')" in a Widget method yields a CALL_REFERENCE to main.draw; negative: unknown receiver + AUTOLOAD elsewhere emits nothing. + +### perl: reviewer-surfaced missed items (wave 4 candidates) + +- **[对拍A]** perl-branch-types-fix: perl_branch_types names if_statement/unless_statement/foreach_statement/while_statement (lang_specs.c:617-618) but the vendored grammar has NONE of these — its kinds are conditional_statement, loop_statement, cstyle_for_statement, for_statement, try_statement (parser.c ts_symbol_names) — so set_def_complexity undercounts every Perl sub's cyclomatic complexity to near-zero (only for_statement matches).

This makes IMPORTS edges materialize for Perl repos TODAY — an independent graph-quality win — and is the hard prerequisite for both cbm_pxc_build_import_map and cbm_pxc_filter_defs_for_file to feed the cross-file LSP; without it perl-cross-file-lsp silently resolves own-module only. +- **[对拍A]** stale-suppression-comments-and-interplay: pass_calls.c:596-598 and pass_parallel.c:2466-2472 both still say 'Perl has no LSP resolver' (false since perl_lsp landed; cbm.c:1376-1378 wires it), and once cross-file Perl LSP lands the is_method weak-match suppression semantics need explicit re-testing — LSP-resolved Perl method calls will start arriving through the resolved_calls join while the guard still drops weak registry matches, so both paths' edge sets must be re-verified for seq/parallel determinism. +- **[对拍B]** perl-exporter-export-model — Collect `our @EXPORT = qw(...)`, `our @EXPORT_OK`, and `%EXPORT_TAGS` from Perl modules at extraction (plus Exporter detection via @ISA/use parent 'Exporter' or `use Exporter 'import'`), store them on the module def, and teach the cross-file import map that `use Foo;` with NO list imports Foo's @EXPORT defaults and `use Foo qw(:tag :all)` expands tags — the analyst's cross-file plan only handles explicit qw() lists, missing the single most common import style in real Perl code (nothing anywhere in perl_lsp.c or extract_defs.c touches EXPORT today). +- **[对拍B]** perl-push-isa — Recognize `push @ISA, 'Base';` / `unshift @ISA, ...` / `push @Pkg::ISA, ...` (a function_call whose first argument is the ISA array) in perl_pass1_scan_inner (perl_lsp.c:1333-1345 handles only assignment_expression today) and in the shared inheritance matcher of perl-package-class-nodes — a ubiquitous classic-OO idiom (pre-parent.pm code, DBI/CGI-era subclassing) that currently yields zero inheritance knowledge. +- **[对拍B]** perl-use-constant — Handle `use constant NAME => expr;` and the hash form `use constant { A=>1, B=>2 };` (a use_statement whose module field is 'constant') to emit Constant defs under the current package and let bare NAME references resolve; the analyst listed this in gaps but shipped no proposal for it. +- **[对拍B]** perl-mro-super-order — Fix method-resolution ordering: perl_lookup_method (perl_lsp.c:317-378) pushes @ISA parents onto a stack and pops last-first, traversing parents RIGHT-to-left, while Perl's default MRO is left-to-right depth-first (push in reverse to fix, ~5 lines); and SUPER:: uses only the FIRST @ISA entry (process_package_decl:1130-1140, dispatch :859-871) while real SUPER:: searches every parent in @ISA order — multiple-inheritance code can resolve to the wrong sub or miss entirely. +- **[对拍B]** perl-accessor-generators — Recognize `__PACKAGE__->mk_accessors(qw(a b))` / mk_ro_accessors / mk_wo_accessors (Class::Accessor family) and Class::XSAccessor's import-hash form in PASS 1, recording generated accessor names per package (like Moose has attrs, unknown-typed) so $self->attr calls and chains in the large legacy accessor-generator population stop dead-ending; the analyst lists Class::Accessor only as a moose_mode gate module and never handles mk_accessors itself. +- **[对拍B]** perl-moose-method-modifiers — `before/after/around 'name' => sub {...}` bodies are top-level anonymous subs, so every call inside them is dropped today (perl_emit_resolved requires an enclosing func QN, perl_lsp.c:630); synthesize a caller context for the modifier body (e.g. module.name or module.name@around) and emit a reference edge to the named modified method, so Moose-heavy codebases keep the call edges that live inside their modifiers. + +Reviewer implementation orders — A: perl-invocant-signatures, perl-test-ecosystem, perl-branch-types-fix, perl-corinna-class, perl-stdlib-538, perl-require-imports, perl-pkgmap-module-resolution, perl-cross-file-lsp, perl-exports-model, perl-moose-attrs, perl-web-routes, perl-package-class-nodes, perl-dynamic-dispatch | B: perl-invocant-signatures, perl-test-ecosystem, perl-push-isa, perl-cross-file-lsp, perl-exporter-export-model, perl-corinna-class, perl-moose-attrs, perl-stdlib-538, perl-web-routes, perl-package-class-nodes, perl-require-imports, perl-use-constant, perl-dynamic-dispatch, perl-mro-super-order, perl-accessor-generators, perl-moose-method-modifiers + +## go + +

Small self-contained correctness patch (balanced-bracket recursive text parser or reuse of the AST path during Phase 1), and a hard prerequisite for range-over-func to work on project iterator functions. +- **[对拍A]** go-router-group-prefixes: route groups lose their prefix — gin r.Group("/api"), chi Mount/Route, echo Group, gorilla PathPrefix().Subrouter() are unhandled anywhere (zero grep hits for Group/PathPrefix/Subrouter in src/pipeline + service_patterns.c), so g.GET("/users", h) emits __route__GET__/users instead of /api/users; cross-service HTTP rendezvous QNs are wrong for the majority of real Go services, which are group-structured. Tractable per-file: the Go LSP already tracks callable aliases in scope, and a group-var → prefix binding recorded at the .Group("/api") call site can be consulted by find_route_path_in_args/emit_route_registration when the receiver is a known group alias; applies to express Router({prefix}) and FastAPI include_router(prefix=...) too, which have partial handling via .include_router mounting but the same missing composition. +- **[对拍B]** route-group-prefix-composition: gin/echo/fiber `g := r.Group("/api/v1")` and chi `r.Route("/p", func(r){...})`/Mount nesting are ignored — grep shows no Group handling anywhere, so nested registrations emit Route nodes with only the leaf path ("/users" instead of "/api/v1/users"), breaking client-server rendezvous in the frameworks that dominate existing Go code; track group-variable→prefix bindings per file and prepend at emission (and while there, unwrap middleware-wrapped handler args `mw(handler)` before cbm_registry_resolve in emit_route_registration so wrapped handlers still get HANDLES). +- **[对拍B]** registry-test-and-platform-hygiene: nothing anywhere marks defs from _test.go files or GOOS/GOARCH-suffixed files (file_linux.go/file_windows.go, //go:build) — the analyst listed build-tag awareness as a gap but proposed nothing; mocks in _test.go become interface implementers in the shared Tier-2 registry (silently defeating sole-implementer resolution) and platform pairs double-register identical QNs; add an origin flag (test-file, build-constrained) on CBMLSPDef/CBMRegisteredType, filter test-file candidates from satisfaction scans, and dedup same-QN platform variants by preferring one canonical GOOS. +- **[对拍B]** connect-twirp-vanity-rpc: connect-go (`path, handler := greetv1connect.NewGreetServiceHandler(impl)`) and Twirp (`pb.NewHaberdasherServer(impl)`) server registrations produce no HANDLES — a fast-growing slice of 2024-2026 Go RPC services; the client side already accidentally works via the "ServiceClient" QN substring sniff (pass_parallel.c:2032), so recognizing NewHandler/NewServer calls with an impl argument and emitting the same __grpc__Service/Method HANDLES rides the exact machinery of go-grpc-server-handles for one extra suffix table. +- **[对拍B]** go-embed-directive: //go:embed comment directives above var declarations (embed.FS/string/[]byte, Go 1.16+, ubiquitous for templates, SQL migrations, static assets) are completely ignored; capture the embed patterns during Go def extraction and attach them as a property on the var definition (optionally an edge to matching files) so agents can answer "where does this template/migration come from". +- **[对拍B]** iota-const-block-typing: in `const ( A Kind = iota; B; C )` only A gets type Kind — const_spec handling (go_lsp.c:1196-1229) treats each spec independently and implicit-repetition specs bind unknown, so stringer-style enum constants (pervasive in Go) lose their type for method dispatch and cross-file registration; propagate the previous typed spec's type through the block in go_process_statement and in the package-level registration scan. + +Reviewer implementation orders — A: go-crossfile-interface-method-names, go122-servemux-route-patterns, go-stdlib-modern-packages, go-return-type-text-func-map-parser, go-range-over-func-int, go-embeds-into-crossfile-defs, go-interface-embedding-method-sets, go-promoted-method-satisfaction, go-interface-scan-memo, go-fuzz-and-subtests, go-new-grammar-expr-nodes, go-grpc-server-handles, go-generic-type-instantiation, go-struct-tags-field-metadata, go-router-group-prefixes | B: go-crossfile-interface-method-names, go122-servemux-route-patterns, route-group-prefix-composition, go-stdlib-modern-packages, go-fuzz-and-subtests, go-range-over-func-int, gomod-replace-directives, go-new-grammar-expr-nodes, go-interface-scan-memo, go-interface-embedding-method-sets, go-generic-type-instantiation, go-grpc-server-handles, connect-twirp-vanity-rpc, go-struct-tags-field-metadata, registry-test-and-platform-hygiene, go-embed-directive, iota-const-block-typing + +## rust + +

The LSP join (lsp_resolve.h:400 exact strcmp) happens to agree between the two wrong sides, but pass_calls.c calls_find_source:461 then fails to find a graph node with `` in the QN and attributes every call from a generic impl method body to the File node; Phase B2's return-type patch (strcmp receiver 'mod.Stack' vs registered 'mod.Stack') silently no-ops so chained calls on generic types lose AST return types.

Recursive expansion carries the accumulated `::` prefix into nested groups so `use tokio::{sync::{mpsc, oneshot}, task};` yields three correct (alias, full-path) entries — today the strchr('{')/strtok(',') logic emits garbage aliases like '{HashMap'. Because the walk starts at the `argument` field, the `pub`/`pub(crate)` visibility_modifier is skipped structurally, fixing `pub use` declarations that currently store 'pub use foo::Bar' as a module path (rust_resolve_use returns it verbatim and resolution dies).

This covers actix-web and rocket verbatim (rocket's '/item/' param syntax is already canonicalized by cbm_route_canon_path in pass_route_nodes.c:52). Setting def.route_path/route_method is sufficient — pass_route_nodes.c phase 2a (:406) already materializes Route + HANDLES from those properties. actix `#[route("/p", method="GET")]` maps method from the kwarg else ANY.

Cross-file: when extract_defs records a Rust async fn's return_type text, wrap it as "Future<...>" so rust_parse_return_type_text reproduces the same shape through CBMLSPDef without any ABI change (prelude maps Future → core.future.Future). Seeded crates already store post-await returns (e.g. reqwest send → Response) and must NOT be wrapped — wrap only AST-harvested project fns.

Fix at def-collection time: when pxc converts a Rust CBMFileResult's defs, scan each type-like def's decorators for the curated derive table (export the table from rust_lsp.c as cbm_rust_curated_derives()) and synthesize (1) one CBMLSPDef impl-relation record per derive (is_rust_impl_relation=true, receiver_type=type QN, trait_qn=canonical trait) — rust_populate_cross_registry:6185 already materializes these into embedded_types, letting trait-default dispatch resolve clone/eq via the stdlib trait methods — and (2) one Method CBMLSPDef per synthesized static (default/parse/try_parse) with receiver_type and return_types=the type's QN so UFCS Type::default() resolves. Serialize these through the existing lsp_surface codec fields only (no new fields → codec round-trip invariant holds). + +**对拍A correction (binding):** Right goal, wrong layer. CBMLSPDef ALREADY carries decorators for every language — pxc_build_lsp_def copies them (pass_lsp_cross.c:406), and the lsp_surface codec round-trips them as 'dec' (lsp_surface.c:103 encode, :260 decode) — so synthesizing extra CBMLSPDef records at pxc collect time (with its calloc-sizing, marking, and gbuf-leak concerns) is unnecessary. Corrected scope: (1) add `const char **decorators` to CBMRustLSPDef (rust_lsp.h:309-325 — field absent today) and copy it in the two conversion sites (cbm_rust_build_cross_registry's field copy rust_lsp.c:6338-6354 and pxc_lspdefs_to_rust in pass_lsp_cross.c); (2) factor Phase A2's curated-derive scan (:5809-5984) into a static helper in rust_lsp.c taking (reg, arena, type_qn, decorators, type_idx, trait_names); (3) call it from BOTH cbm_rust_build_local_registry and rust_populate_cross_registry's type loop. No header-visible table accessor, no pass_lsp_cross.c synthesis, no codec change, and per-file/cross parity holds by construction because both cross paths (per-file fallback :6426 and Tier-2 shared :6356) share rust_populate_cross_registry. Est drops to S-M; risk drops to low — synthesized entries exist only inside registry builds, and duplicate-vs-explicit-impl semantics are byte-identical to today's per-file behavior (rust_registered_type_add_embedded already dedupes links). + +**对拍B correction (binding):** Simpler, parity-safe mechanism than synthesizing extra CBMLSPDef records at collection time: add `decorators` to CBMRustLSPDef (the header explicitly reserves it for Rust-specific fields without ABI impact, rust_lsp.h:305-308), copy it through the two conversion sites, and run the SAME curated table (exported per the proposal) inside rust_populate_cross_registry alongside its existing impl-relation materialization (:6185-6208). One code site then covers BOTH the shared Tier-2 build (:6327) and the per-file cross path (:6397), guarantees byte-parity with per-file A2 by construction, keeps all_defs free of synthetic records (their own stated risk), and dedupe against explicit impls falls out of rust_registered_type_add_embedded.

Derive the crate root per file instead: (1) if the manifest is present and module_qn's path segments start with a workspace member's path (e.g. crates.net), the crate root is project + member path + optional 'src' segment; (2) else locate the LAST 'src' segment in module_qn and take everything through it; (3) fall back to the current two-segment heuristic. Additionally, when the resolved crate-rooted QN misses the registry, retry with a '.lib' segment appended to the root (items defined in lib.rs carry the file-stem 'lib' in their QNs since cbm_fqn_compute never collapses lib.rs/mod.rs/main.rs) and, for mod.rs, extend rust_registered_relative_path's dual probe with a '.mod'-collapsed candidate. All probes remain fail-closed (registry-lookup-gated, ambiguous → unchanged) so no false edges are introduced. This unlocks crate:: paths — the dominant absolute-path idiom in workspace crates (tokio/serde/cargo style layouts) — which today resolve to nonexistent 'project.crates.*' prefixes and die in the unresolved bucket. + +**对拍B correction (binding):** Extend the crate-root derivation to the OTHER cargo target roots: files under tests/, examples/, benches/, and src/bin/*.rs are each their own crate — crate:: there must resolve within that file tree (for a single-file tests/x.rs, to that file's own module), never to src/; the proposed "last src segment" heuristic (2) silently misroutes all of them.

Effects: (1) `MyEnum::Variant(x)` call_expression resolves through the existing UFCS path (registry method hit at rust_lsp.c:1654/4480) instead of emitting 'function_not_in_registry' unresolved noise, and the expression types as MyEnum so subsequent match/method dispatch works; (2) extend rust_bind_pattern's tuple_struct_pattern case: when the matched type is a plain NAMED user enum (not a template), resolve the pattern's path to a registered variant and bind sub-patterns to the variant's recorded payload types — today only Option/Result-style templates bind, so match arms over user enums leave bindings untyped and every method call on them unresolved. Scope is per-file + Tier-2-cross via the same AST walk in the local build; the def-driven shared registry can follow later by exporting variants as defs (note as limitation). + +**对拍A correction (binding):** Keep the mechanism, correct the stated scope: variant registration in cbm_rust_build_local_registry's Phase B reaches ONLY the Tier-1 per-file resolver (cbm_run_rust_lsp, cbm.c:1412). The analyst's 'per-file + Tier-2-cross via the same AST walk in the local build' is wrong — Tier-2 (cbm_rust_build_cross_registry:6327) and the per-file cross fallback (:6426) are def-driven through rust_populate_cross_registry and never run the local AST build, so cross-file variant constructions stay unresolved until variants are exported as defs (the proposal's own noted follow-up). Implement as: enum_item branch beside struct_item in Phase B (:5637) registering each enum_variant as a CBMRegisteredFunc with receiver_type = enum QN and payload types via rust_parse_type_node, plus the tuple_struct_pattern extension (:3841-3856) resolving the pattern path to a registered variant when the matched type is a plain NAMED user enum. Same-file enums (the dominant match-arm case) get typed bindings; cross-file is explicitly out of scope for this change. + +**对拍B correction (binding):** Fix the Tier-2 scoping, which as written is wrong: the shared-registry production path (cbm_run_rust_lsp_cross_with_registry, rust_lsp.c:6363+) never runs the local AST build, so an AST-walk-only registration leaves cross-file E::A(x) noise exactly where most resolution happens. Emit variants def-side as well — e.g. one Method-shaped CBMLSPDef per variant (receiver_type = enum QN, return_types = enum QN, payload types via signature_param_types) at extraction or pxc collection — reusing existing codec fields so rust_populate_cross_registry picks them up unchanged; then the per-file AST walk and the def-driven registries agree (add a parity test). + +Test plan: tests/test_rust_lsp.c: TEST(rustlsp_enum_variant_payload_binding) fixture "struct P; impl P { fn go(&self){} }\nenum E { A(P), B }\nfn run(e:E){ match e { E::A(p) => p.go(), E::B => {} } }" asserting require_resolved(r, "run", "P.go"); TEST(rustlsp_enum_variant_ctor_call) "let e = E::A(P); " asserting the construction resolves to E.A and no unresolved 'function_not_in_registry' entry exists for it. + +### rust-from-into-conversion-edges (P2/S, wave 4) + +**Resolve .into() to the concrete From impl when the target type is known** + +Files: internal/cbm/lsp/rust_lsp.c (let_declaration handler ~3925, rust_resolve_call_expression_inner field_expression branch ~4377); tests/test_rust_lsp.c + +Scope: Today x.into() falls through to the prelude best-effort edge '.into' (lsp_prelude_trait, conf 0.85) — a synthetic target that rarely names a real def.

Phase B2's AST harvest patches only the per-file (Tier-1) registry, so any cross-FILE method chain (let s = other_mod::Stack::new(); s.push(...)) loses typing today. Fix is one field capture (the function_item's return_type field text) in extract_rust_impl; it flows through the existing CBMLSPDef.return_types and lsp_surface codec untouched, and it is a prerequisite for the async proposal's cross-file impl-method coverage. Note the free-function path already records return_type (generic rt_fields at extract_defs.c:3701-3710), which makes the impl-method omission a pure inconsistency. +- **[对拍A]** Registry-harvest recursion: Phase B (struct fields/trait methods), B1 (free-fn returns) and B2 (impl-method returns) in cbm_rust_build_local_registry walk only ROOT children (rust_lsp.c:5629-5634, :5761-5765, :5991-5996), so types, functions and impls inside inline `mod` blocks get no field registration and no return-type harvest even after the trait-default/nested-scopes proposal makes Pass 2 recurse.

Related ordering hazard to fix in the same rewrite: the use map is first-match-wins (rust_resolve_use rust_lsp.c:311-321) and text-parsed entries are inserted BEFORE the unified-extractor imports bridge (:6109-6116), so a malformed early entry permanently shadows a correct bridged one — define dedupe/priority semantics when replacing the parser. +- **[对拍A]** Opportunistic rustdoc-JSON ingestion for project docs: rust_rustdoc.c is a working ingester referenced only by lsp_all.c and tests (grep — wired nowhere in src/pipeline). Ingesting target/doc/*.json when it already exists on disk at index time is pure file I/O (no process launch, allowed under the constraints) and would give typed returns for the project's own crates and its documented dependencies ahead of the full stdlib generator landing; bounded, opt-in, and skippable when absent. +- **[对拍B]** rust-impl-method-return-types: extract_rust_impl (extract_defs.c:5132-5235) records signature and params but NO return_type for impl methods (and it is the only extraction path — the walk dispatches impl_item to it exclusively at :7859-7862), so the production Tier-2/def-driven cross registries (rust_lsp.c:6231-6262 parse d->return_types) type every cross-file project method chain as unknown; per-file Phase B2 masks it locally and hand-built test defs mask it in the parity tests.

CALLS edges require confidence >= 0.6 (CBM_LSP_CONFIDENCE_FLOOR, src/pipeline/lsp_resolve.h:39); unresolved module-attr calls emit at 0.55 and are dropped. + +Test coverage: Suite name `py_lsp` (plus `py_lsp_stress`, perf-gated `py_lsp_bench` / `py_lsp_scale`), run via `make -f Makefile.cbm test-focused TEST_SUITES=py_lsp` (tests/test_main.c:1099-1104). ~90 inline-source tests in /data/code/txd/codebase-memory-mcp/tests/test_py_lsp.c: imports (simple/aliased/from/relative/star/rebinding fail-closed), direct/method/self/inheritance/super/multi-inheritance calls, decorators (classmethod/staticmethod/dataclass-constructor), stdlib (os/collections/pathlib/logging), typing (cast/assert_type/forward refs/Self chains/generic subscripts), narrowing (isinstance/is-not-None/walrus-in-if/match class pattern), containers (comprehensions/dict-subscript/tuple unpack), instance attributes, dunder site joins, cross-file + batch + shared-registry paths, #710 deep-chain perf guards. test_py_lsp_stress.c adds NamedTuple/TypedDict/Protocol/ABC/property-setter/diamond-MRO/match-sequence/closures. NO tests exist for: any Python 2 syntax, parameterized user-generic annotations (the pylsp_pep695_generic_class test at test_py_lsp.c:493 deliberately omits the `[T]`), PEP 695 type aliases, Enum member access, nested/conditional imports, routes (Flask/FastAPI/Django), pytest fixtures. tests/fixtures/ has no Python fixtures (all sources inline). +

Add a bounded recursive descent (depth <= 3) that, on meeting a module-level `try_statement`, `if_statement`, `elif_clause`, `else_clause`, `except_clause`, `finally_clause`, `with_statement`, or `block` node, walks its named children looking for import_statement/import_from_statement/future_import_statement and processes them with the existing process_py_* helpers. Do NOT descend into function_definition/class_definition/decorated_definition (function-local imports would pollute module scope and CBMImport carries no scope). This makes `try: import simplejson as json / except ImportError: import json` and `if TYPE_CHECKING: from .models import User` visible to (a) IMPORTS edges, (b) the cross-file import map (pass_lsp_cross.c:753), (c) py_lsp scope binding so string annotations like "User" resolve. In py_lsp.c, py_replay_import_statement is driven by top-level statement kinds in py_lsp_process_file pass-1; the conservative join for compound statements already invalidates rebound names, and py_bind_import_index binds from the recorded metadata, so no resolver change is strictly required — the resolver classifies each CBMImport against the AST via py_import_kind_from_ast which scans root-level statements only; extend that scan with the same bounded descent so the new imports classify as PY_FROM_IMPORT/etc. rather than UNCLASSIFIED. Duplicate locals from the try/except shim (json twice) already fail closed via PY_IMPORT_AMBIGUOUS, which is correct. + +**对拍A correction (binding):** Keep the extraction-side bounded descent (depth<=3, skip function/class/decorated bodies) and mirror it in py_import_kind_from_ast. Add the required resolver half: (a) in pass-1, special-case module-level `if TYPE_CHECKING:` if_statements (condition is the TYPE_CHECKING identifier or typing.TYPE_CHECKING attribute) and replay their nested import statements via py_replay_import_statement — sound because the binding is types-only NAMED and callable upgrade still requires registry proof; (b) for try/except shims, do NOT sequentially replay per-arm (last-wins fabricates certainty): collect all nested import bindings per local across the whole compound and bind only when qn+kind agree across arms (reuse py_replay_import_local's conflict discipline at py_lsp.c:4612-4642), else leave the existing UNKNOWN. Rewrite pylsp_import_typing_only_still_binds through the real extract path. Size becomes M+, risk honest otherwise. + +**对拍B correction (binding):** Keep the extraction descent exactly as proposed (bounded depth, skip function/class bodies, dedupe by local+module+byte). Additionally extend pass-1: when a root-level try_statement/if_statement/with_statement is met, first run the existing py_invalidate_possible_bindings join, then descend (same bounded kinds) and for each found import statement call py_replay_import_statement — py_replay_import_local's chosen/conflicting logic (py_lsp.c:4612-4642) already fails closed when two candidates disagree, so the try/except json-shim double-binding stays UNKNOWN while a single-candidate `if TYPE_CHECKING: from svc import X` binds exactly.

(1) Builtins: register into the registry under 'builtins.' — xrange (returns range-like iterable of int), unicode/basestring (alias_of builtins.str), long (alias_of builtins.int), raw_input (returns str), unichr, execfile, reload, cmp, apply, buffer, intern, file (alias_of io file object) — a static hand-written function py2_compat_register(reg, arena) called from cbm_run_py_lsp (py_lsp.c:4933) and cbm_py_build_cross_registry (5147) right after cbm_python_stdlib_register; ~30 entries, O(1) per file added cost. (2) dict iter-methods: extend the is_dict_like special-case in py_eval_expr_type (py_lsp.c:1685-1706) with iteritems -> ItemsView[K,V], iterkeys -> KeysView[K], itervalues -> ValuesView[V], has_key -> bool, and register matching CBMRegisteredFunc rows on builtins.dict so the calls also emit lsp_builtin_method edges. (3) Module aliases: a static table {urllib2 -> urllib.request, ConfigParser -> configparser*, StringIO -> io, cStringIO -> io, Queue -> queue, httplib -> http.client, cPickle -> pickle, SocketServer -> socketserver, urlparse -> urllib.parse, itertools.izip -> zip...}; in py_bind_import_index (py_lsp.c:584), when a module import's qn matches the table AND the py3 twin exists in the registry, bind MODULE() instead so urllib2.urlopen() resolves through the existing typeshed rows (strategy stays lsp_module_attr). (*requires configparser in the allowlist — see py-stdlib-allowlist proposal; ship the alias rows regardless, they no-op until the twin exists.) (4) Optional dialect tag: while walking, if a module contains print_statement/exec_statement nodes, set a result property (e.g. module def property python_dialect=2) so agents and later passes can see it; the __future__ import row (extract_imports.c:264) is already available as a signal. + +**对拍A correction (binding):** Three corrections: (1) register the compat tables at ALL THREE registry-construction sites — cbm_run_py_lsp (py_lsp.c:4933), cbm_run_py_lsp_cross (py_lsp.c:5110, MISSED by the plan — this is the tier-1 cross path), and cbm_py_build_cross_registry (py_lsp.c:5147); (2) the alias hook must cover the PY_DIRECT_IMPORT_UNALIASED branch which binds MODULE(local), not MODULE(qn) (py_lsp.c:599-601); (3) resolved_calls-level tests will pass, but actual CALLS edges to builtins.xrange/unicode/dict.iteritems need matching def injection in py_builtins.c (py_builtins_inject_defs — an 89-line fixed table; see the rationale comment at py_lsp.c:4921-4927), or the edges silently drop at materialization. Keep the project-shadow gate and the optional dialect tag. + +**对拍B correction (binding):** (1) Extend py_builtins.c's kPyBuiltinNodes with the py2 names being registered (builtins.xrange/unicode/basestring/long/raw_input, builtins.dict.iteritems/iterkeys/itervalues/has_key) so pass_calls can mint edges; assert at least one graph-level CALLS edge in tests, not just require_resolved. (2) Hook py2_compat_register at ALL THREE stdlib registration sites — cbm_run_py_lsp (py_lsp.c:4933), cbm_run_py_lsp_cross (5110), cbm_py_build_cross_registry (5147). (3) Note honestly that urllib2.urlopen(u).read() chains stay unresolved until stdlib return types exist (see missed item py-stdlib-return-types — the table has zero rf.signature entries); the alias itself only buys direct-call resolution + constructor typing (StringIO()→io.StringIO instance methods DO work since method existence is registered).

(a) At annotation-parse time: in py_resolve_annotation's generic-container fallback (py_lsp.c:3877 `return cbm_type_template(ctx->arena, btrim, ...)`), before building the TEMPLATE, look the base name up in scope (an imported class binds NAMED with its full qn) and in the registry as '.'; when found, use the QUALIFIED name as template_name. Mirror in py_parse_type_text_qn (3655) using its module_qn parameter (skip the known typing/builtin container names — reuse the typing_names table at 3710 plus list/dict/set/tuple/frozenset/deque). (b) At receiver time (defense for cross-file template names that stayed bare): in py_emit_call_for's TEMPLATE branch (2802) and py_eval_expr_type's (1604), after the 'builtins.' and bare-tname probes, additionally probe py_lookup_attribute(ctx, '.', attr) and, if tname is bound in scope to a NAMED type, that qn. Emit with the existing lsp_generic_method strategy.

Also add a pass-1 branch in py_lsp_process_file so module-level `type Handler = Callable[[Request], Response]` binds before function bodies run (today it falls into py_invalidate_possible_bindings at py_lsp.c:4479 and only invalidates). PEP 613 `X: TypeAlias = Y` already works through the annotated-assignment path since TypeAlias is not a wrapper — verify and add 'TypeAlias' to the annotation wrapper skip so the RHS value type is used. (2) walrus: add named_expression/assignment_expression handling directly to py_process_statement (bind left identifier to py_eval_expr_type of the value) so `while (chunk := f.read(1024)):`, comprehension conditions, and bare-expression walruses bind — py_resolve_calls_in_inner already visits every node, so the existing if-condition-only py_bind_walrus_in call (py_lsp.c:3046) becomes one caller among many; keep it (idempotent rebind). + +Test plan: tests/test_py_lsp.c: (1) `class Resp:\n def send(self):\n return 1\ntype R = Resp\ndef use(r: R):\n return r.send()` — require_resolved(use, send); (2) `type Alias[T] = list[T]` parses and does not crash, `def f(x: Alias[int]): x.append(1)` resolves append; (3) `def g(f):\n while (chunk := f.read()):\n chunk.upper()` with f annotated as io-like or chunk via `f.read` returning str from a local class — require_resolved(g, upper). + +### py-class-constants-enum-members (P1/M, wave 2) + +**Register unannotated class-body assignments as fields (Enum members, class constants)** + +Files: /data/code/txd/codebase-memory-mcp/internal/cbm/lsp/py_lsp.c (py_process_class first pass ~4107-4128, py_eval_expr_type attribute NAMED branch ~1584) + +Scope: Extend py_process_class's first pass: for `expression_statement > assignment` with an identifier LHS and NO annotation, evaluate the RHS with py_eval_expr_type (module scope is live at that point in pass 2; guard eval_steps) and py_register_instance_field(ctx, enclosing_class_qn, name, rhs_type); skip dunder names (__slots__, __metaclass__, __tablename__ can be registered too — they are harmless and useful). Special-case Enum: when the class's embedded_types contain a base whose short name is Enum/IntEnum/StrEnum/Flag/IntFlag (string check on rt.embedded_types built by py_register_def, py_lsp.c:4763), register each member's field type as NAMED() instead of the literal's type, so `Color.RED` evaluates to a Color instance and `Color.RED.name/.value` plus user-defined enum methods (`Color.RED.describe()`) resolve; also gives isinstance-style narrowing the right receiver. This also fixes `cls.DEFAULTS.copy()` / `self.TIMEOUT` constant access chains on ordinary classes, a very common pattern. + +**对拍A correction (binding):** Restrict registration to RHS shapes whose eval is trustworthy: literals (py_literal_type kinds), container literals, and constructor calls of in-scope NAMED classes; for identifier/attribute/other-call RHS register nothing (or UNKNOWN) — this also keeps the eval budget flat.

(2) except-tuple: in the try_statement handler (py_lsp.c:2503-2509), when exc_type is a `tuple` node, resolve each element with py_resolve_annotation and bind the alias to cbm_type_union instead of feeding the raw "(IOError, OSError)" text through py_resolve_annotation — fixes both py2 `except (A,B), e:` and py3 `except (A,B) as e:`; the UNION attribute path (py_lsp.c:1618) then resolves single-match methods like e.errno chains. + +**对拍A correction (binding):** Split and re-stage: ship (1) the except-tuple union binding via direct tuple-node walking (S, immediate py2+py3 win) and (2) extraction-side __all__ capture onto module def properties (S, agent-visible surface).

Add a CBMNegMemo to PyLSPContext (arena-backed, dies with the file), gate on ctx->registry->read_only exactly as lsp_neg_memo.h's contract requires (the tier-2 sealed path — the biggest indexing path), key with cbm_negmemo_key(site_tag, type_qn, member_name), check after the direct cbm_registry_lookup_method hit (collision-safe pattern per the header), insert on the NULL return. The per-file overlay lookup (py_overlay_lookup_field) must stay OUTSIDE the memoized rung or be keyed into the check, since overlay contents change during resolve — memoize only the registry-pure base walk.

(b) Optionally also memo py_lookup_attribute_depth entry (methods only — never the field cascade).

Correctness: tests/test_py_lsp.c stress case where a member is found on the deepest base AFTER a same-named miss elsewhere in the file (memo must not convert that to a miss — different type_qn keys), plus an overlay case: self.x registered mid-file must still be found after an earlier miss for the same (class, x) — proving the overlay rung is not memoized. + +### python: reviewer-surfaced missed items (wave 4 candidates) + +- **[对拍A]** py-stdlib-fallback-registry: build the typeshed stdlib registry ONCE per process (finalized + sealed) and chain per-file registries to it via CBMTypeRegistry.fallback — the mechanism already exists and is consulted by every lookup (type_registry.h:89-94; type_registry.c:576/620/664/811/835), yet Python re-registers the entire 23.5k-line table per file in cbm_run_py_lsp (py_lsp.c:4933) and again in the tier-1 cross path (py_lsp.c:5110). Removes the dominant per-file fixed cost and is the enabler that makes any allowlist growth safe. +- **[对拍A]** py-tier2-return-qualification: py_register_lsp_defs registers cross-file return types as bare NAMED(ret_str) with no def_module_qn qualification (py_lsp.c:5056), unlike the per-file path which routes through py_parse_type_text_qn with module_qn (py_lsp.c:4870-4884) — every cross-file method chain hanging off a bare return annotation ('-> Client') silently fails receiver lookup against the qualified registry ('pkg.mod.Client'). One-line-class fix with outsized cross-file impact; prerequisite for pytest fixture param typing. +- **[对拍A]** py-module-attr-submodule-index: the submodule detection probe in py_eval_expr_type's MODULE branch linearly scans every registry func per unresolved module.attr access (py_lsp.c:1570-1581; the comment itself says it 'can dominate') — on the sealed project-wide tier-2 registry this is the real O(all-funcs)-per-miss hazard, fixable with a finalize-time module-prefix index or a negative memo (folded into the retargeted py-neg-memo-port verdict, but the analyst's gap list never identified it). +- **[对拍A]** py-typechecking-test-is-misleading: tests/test_py_lsp.c:260-276 (pylsp_import_typing_only_still_binds) hand-feeds the import via bind_imports_into_ctx and its comment falsely states 'extract_imports emits CBMImport entries regardless of guard' — extraction is root-level-only, so the guard gap is masked by the suite's own documentation; rewrite through the real extract path when nested-import extraction lands. +- **[对拍A]** py2-tuple-parameters: `def f(a, (x, y)):` parses cleanly (probe-verified tuple parameter node) but py_bind_parameters (py_lsp.c:3957-4027) has no tuple_pattern case, so such params bind nothing — a small addition that belongs in the py2 dialect pass. +- **[对拍A]** py-package-reexport-resolution: `from .api import *` in __init__.py plus __all__ is the standard package-surface pattern; beyond the analyst's importer-side invalidation-narrowing, the higher-value half is binding the __all__-listed names to their source-module defs so calls through the package facade resolve — currently a wildcard both nukes local proof AND contributes no bindings. +- **[对拍B]** py-stdlib-return-types — The generated typeshed table carries ZERO return types (gen-py-stdlib.py's StubFunction/StubMethod store only names; `rf.signature` appears 0 times in python_stdlib_data.c, e.g. os.getcwd at 15633 has none), and py_func_return_type_recv (py_lsp.c:1307-1332) returns UNKNOWN without a signature — so every chain through a stdlib call dead-ends (open(p).read(), s.split(',')[0].strip(), re.match(...), Path(x).read_text(), datetime.now().isoformat(), and the py2 twins). Emit return-type texts in the generator and build rf.signature via the same py_parse_type_text_qn machinery py_register_def already uses (py_lsp.c:4867-4886); single highest-value stdlib change, bench-gated like the allowlist work. +- **[对拍B]** py-stdlib-reexport-aliases — The generator registers symbols only under their defining submodule: 'unittest.TestCase' has zero rows while 'unittest.case.TestCase' exists (python_stdlib_data.c:20616), so `class MyTest(unittest.TestCase)` gets an embedded base that resolves to nothing and every self.assertEqual/assertRaises in every unittest file (py2 AND py3) is unresolved. Emit alias rows (rt.alias_of already exists and py_lookup_attribute_depth follows it at py_lsp.c:1054-1057) for package-__init__ re-exports: unittest.*, os.path, collections.abc, asyncio.* and friends. +- **[对拍B]** py-init-reexport-chase — `from pkg import Foo` where pkg/__init__.py does `from .mod import Foo` (the default facade idiom of real packages) resolves to a nonexistent 'pkg.Foo': pxc_python_import_from_metadata (pass_lsp_cross.c:704-748) is one-hop — exact node, else Module-node + leaf guess. Chase up to two hops through the __init__ file's own recorded import metadata (available in the pipeline caches) before falling back; unlocks cross-file typing for most package-structured projects. +- **[对拍B]** py-with-contextmanager-unwrap — The with-as binder unwraps __enter__/__aenter__ only for NAMED context types (py_lsp.c:2439-2456); a project function decorated @contextlib.contextmanager and annotated `-> Iterator[Connection]` evaluates to TEMPLATE(Iterator,[Connection]) and binds the raw Iterator, so `with open_db() as db: db.execute()` resolves nothing. In the with handler, when the value types as TEMPLATE Iterator/Generator/AsyncIterator/AsyncGenerator/ContextManager/AsyncContextManager, bind the first template arg — tiny fix, ubiquitous idiom, and the same unwrapping the pytest-fixture proposal needs. +- **[对拍B]** py-assert-isinstance-narrowing — `assert isinstance(x, Foo)` and `assert x is not None` narrow nothing (no assert_statement case anywhere in py_lsp.c) even though py_match_isinstance (2847) and py_strip_none (2965) already exist; add an assert branch in py_process_statement that binds into the current scope (Python semantics: the narrow holds for the rest of the block). The dominant narrowing idiom of untyped py2/legacy code the user is targeting. +- **[对拍B]** py-typevar-bound-methods — `T = TypeVar('T', bound=Connection)` then `def f(x: T): x.execute()` resolves nothing: the assignment binds T to NAMED(typing.TypeVar) via the constructor path and py_resolve_annotation('T') finds that garbage in scope. Special-case TypeVar(...) assignments in py_process_statement: parse the bound= kwarg (or single constraint) and py_scope_bind the alias name to the bound's resolved type so bounded-generic params dispatch through the bound — standard in typed library code. +- **[对拍B]** py-celery-task-edges — `@app.task def send_email(...)` invoked as `send_email.delay(...)` / `.apply_async(...)` / `.s(...)` produces no CALLS edge (celery appears only as a service-pattern lib marker, service_patterns.c:209); resolve the delay-family attribute calls on identifiers that name registry functions whose decorator_qns contain task/shared_task to the task function itself (reuse py_decorator_short_name_is; mirror the fixture-proof fail-closed discipline). The 'who enqueues this job' question is a top agent query on celery repos. +- **[对拍B]** py-aiohttp-tornado-routes — Both frameworks are in the target brief and have zero route extraction: aiohttp's `app.router.add_get('/p', handler)` / `web.get('/p', h)` route-table lists and tornado's `Application([(r"/p", Handler)])` tuples produce no Route nodes (service_patterns.c has only .add_route/.include_router; add_get/add_post absent; tornado tuples are not calls at all). Extend the proposed urls.py-style call walker with aiohttp add_/web. and tornado (pattern, Handler) tuple lists, emitting the same Route+HANDLES shapes. +- **[对拍B]** py-pyi-stub-indexing — .pyi files are not mapped to Python anywhere (no '"pyi"' hits in lang detection or pipeline), so local stub files and stub-only packages contribute zero defs/types; map the extension to CBM_LANG_PYTHON with a shadowing rule (a sibling .py wins) so `models.pyi`-style stubs feed the registry — cheap way to type C-extension-backed and vendored libraries. +- **[对拍B]** py-importlib-literal-imports — `importlib.import_module("pkg.mod")` with a literal argument (Django INSTALLED_APPS loaders, plugin registries) records no IMPORTS edge and binds nothing; when arg0 is a plain string literal, record a CBMImport in parse_python_imports (module_path = the literal, local = assignment target when present).

Entry points: single-file cbm_run_java_lsp (java_lsp.c:3673) which builds a per-file registry, registers file defs (register_local_func_or_type_from_file:3194), populates field metadata from the AST (populate_class_fields_from_ast:3605) and re-patches generic-preserving method signatures (patch_method_signatures_from_ast:3512); production Tier-2 cross path cbm_java_build_cross_registry (3824, shared sealed registry incl. Kotlin defs) + cbm_run_java_lsp_cross_with_registry (3899, per-file overlay with fallback chaining) — NOTE the cross path does NOT run the field-population or signature-patching passes. Expression typing: java_eval_expr_type (585) covers literals, this/super, identifiers, field_access (847, System.out special-case, array .length), method_invocation (1099) with well-known generic return substitution (substitute_generic_return:1039, is_value_typed_container:1002, is_map_like:1022) and carrier propagation for chained streams (propagate_template:2355), object creation, casts, ternary, binary (String-concat aware), switch_expression (first-arm only, 763). Type-name resolution java_resolve_type_name (474): enclosing-class stack → module_qn → single imports → java.lang table (JAVA_LANG_TYPES:140) → on-demand imports → package → registry-unique-short-name fallback (562, linear scan).

Lambdas: SAM table JAVA_SAM_TABLE (2182, 29 FIs), bind_lambda_args (2415) with receiver-template substitution plus the method-name heuristic method_implies_lambda_args (2298); method references resolve_method_reference (2641) incl.

Cross-file: in extract_defs.c, label record_declaration as "Record" (class_label_for_kind:2820; cbm_label_is_type_like must accept it — C# grammar precedent) and emit each record component as a "Field" def (name, parent_class=record QN, return_type=component type text) next to the class-def push at 4630 so the field fold (companion proposal) carries them; cbm_java_register_lsp_defs then, for label=="Record", additionally registers one zero-arg accessor func per field_defs entry.

Do the synthesis at EXTRACTION instead: in extract_class_def for record_declaration, walk the `parameters` field and (a) emit each component as a "Field" def (name, parent_class=record QN, return_type=component type text) — extract_class_fields (extract_defs.c:6976-6994) never sees them today because it only walks body field_declarations; (b) emit one zero-arg accessor "Method" def per component (skip when an explicit same-name method exists in the body) with return_type = component type — real graph Method nodes solve the edge-target problem and fix Kotlin→Java record interop for free, since both registrars already consume Method defs. Resolver side keeps: record-`parameters` walk added to populate_class_fields_from_ast for single-file field typing, and the compact_constructor_declaration + instance-initializer `block` walk in java_process_class_decl (grammar has the node: vendored parser.c sym_compact_constructor_declaration). Canonical-ctor registration is optional — lsp_constructor_synth (java_lsp.c:2963-2971) already lands `new Point(...)` on the class node; add it only if arity-typed ctor matching proves needed.

(2) Neg-memo gating: the OVERLAY is never read_only — gate the memo on the fallback base being sealed AND initialize it only after register_local + the field/signature passes complete, since the memo contract (lsp_neg_memo.h header) requires the consulted registries to be immutable for the memo's lifetime; the overlay is stable during the resolve walk, so this is safe but must be stated as the invariant, not reg->read_only of the overlay. (3) Re-rank as P1: the parity-corpus delta risk is correctly flagged — run jlsp_real_corpus_parity_90_percent and pin strategy flips. + +Test plan: tests/test_java_lsp.c: jlsp_cross_interface_sole_impl — cbm_run_java_lsp_cross with defs[] containing Interface demo.Greeter (is_interface) and Class demo.Hi (embedded_types="demo.Greeter") + Method demo.Hi.greet defined in ANOTHER file's defs, caller `void run(Greeter g){ g.greet(); }` asserting lsp_interface_resolve to demo.Hi.greet (fails today because the impl is not in the overlay); jlsp_two_impls_stays_dispatch (two implementers → lsp_interface_dispatch, proving the cap still holds through the index); perf-guard: extend the existing complexity gate (test_complexity.c shared-package pattern referenced at java_lsp.c:3897) if it covers Java. + +### java-enum-semantics (P2/S, wave 3) + +**Enums: parent java.lang.Enum, Enum method set, synthetic values()/valueOf()** + +Files: internal/cbm/lsp/java_lsp.c (register_local_func_or_type_from_file Pass 1b default-parent:3320-3331, cbm_java_register_lsp_defs:3742); internal/cbm/lsp/generated/java_stdlib_data.c (java.lang.Enum methods near :188); tests/test_java_lsp.c + +Scope: User enums currently get embedded_types=[java.lang.Object] (the implicit-Object default at java_lsp.c:3324 doesn't special-case the "Enum" label) and java.lang.Enum has zero registered methods, so `state.name()`, `Status.valueOf(s)`, `Status.values()[0]` all fail. (1) In both registrars, when the def label is "Enum", default the parent chain to "java.lang.Enum" (which itself parents Object). (2) Stdlib: REG_METHOD java.lang.Enum name/toString→String, ordinal/compareTo→int, equals→boolean, getDeclaringClass→Class. (3) Synthesize per-enum statics at registration: `.values` returning cbm_type_slice(cbm_type_named(QN)) and `.valueOf` returning the enum type — enabling `Status.values()` → enhanced-for element typing (process_enhanced_for:1424 already unwraps slices) and `Status.valueOf(x).name()` chains. Enum-constant references (`Status.ACTIVE.isTerminal()`) already work via field access IF constants are registered as fields — extract_enum_members (extract_defs.c:4633) emits them; extend the field fold/registrar to type each constant as its own enum (receiver-typed field), closing `Status.ACTIVE.method()`. + +**对拍A correction (binding):** Keep (1) label-driven java.lang.Enum default parent in BOTH registrars (d->label=="Enum" is available in Pass 1b at :3227 and in the cross registrar at :3737), (2) Enum method set in the stdlib table (name/toString→String, ordinal/compareTo→int, equals→boolean, getDeclaringClass→Class), (3) synthetic per-enum values()/valueOf statics with lookup-first collision guard. For constants, add the missing extraction step: set parent_class = enum QN and return_type = enum QN on the enum-member defs in extract_enum_members (keeping label "Variable" so graph labels don't churn), then either extend the generalized Java field fold to accept Java Variable rows whose parent is an Enum-labeled def, or walk enum_constant nodes in populate_class_fields_from_ast for single-file (enum constants are direct enum_body children, bypassed by java_type_declaration_body:1639-1651 — the walk must target the raw enum_body). Size grows to S+/M with the extraction touch; still worth it. + +**对拍B correction (binding):** Add: (a) at extraction, stamp enum-constant Variable defs with parent_class = enum QN and return_type = enum QN (Variable already passes pxc_map_label, pass_lsp_cross.c:117); (b) consume Variable defs with receiver_type in cbm_java_register_lsp_defs as fields (Kotlin precedent: kotlin_lsp.c:5323); (c) single-file/overlay: populate_class_fields_from_ast must walk enum_body's enum_constant children explicitly — java_type_declaration_body (java_lsp.c:1639-1651) redirects to enum_body_declarations, skipping constants.

Add "requires_module_directive" handling in extract_imports.c's Java branch: emit a CBMImport with local_name = the module leaf and module_path = the full module name (plus is_static-like flag reuse for `transitive`), giving IMPORTS edges from the module-info File node to the required module name — enough for an agent to see the module graph of a JPMS/multi-module repo. exports/opens directives become properties on the module def (packages list packed into the def's docstring or a decorators-style array) rather than edges, keeping node growth nil. provides X with Y → emit a type-ref usage of both X and Y so DI-style service wiring is discoverable. + +Test plan: tests/test_edge_imports.c (or java coverage suite): fixture module-info.java `module com.app { requires java.net.http; requires transitive com.lib; exports com.app.api; provides com.spi.Handler with com.app.HandlerImpl; }` asserting: imports.count includes java.net.http and com.lib rows; the module def is named com.app; provides emits usages of Handler/HandlerImpl. + +### java: reviewer-surfaced missed items (wave 4 candidates) + +- **[对拍A]** User-defined functional interfaces never bind lambda parameters: bind_lambda_args requires find_sam() over the fixed 29-entry stdlib JAVA_SAM_TABLE (java_lsp.c:2540 `if (!sam) continue;`), so a lambda passed to ANY project-defined @FunctionalInterface (interface UserCallback { void onUser(User u); } — ubiquitous in Spring/callback-heavy code) walks its body with untyped parameters even when the interface and its sole abstract method are fully registered with patched generic signatures. A registry-driven SAM fallback (receiver-registered interface with exactly one declared method → bind from its param types) is a bounded, high-parity win and composes with the Tier-2 signature-patching fix. Suggested slug: java-user-sam-binding. +- **[对拍A]** Anonymous class bodies are structurally mis-scoped: `new Runnable() { public void run() { this.helper(); } }` — java_process_class_decl dispatches only named type declarations (java_lsp.c:1706-1710) and the object_creation_expression branch (:2941-2975) falls through to generic child recursion, so methods inside an anonymous class_body are walked without process_method_decl context: no parameter bindings, enclosing_method stays the OUTER method (edges mis-attributed), and `this` resolves to the outer class. Coverage only asserts no-crash for anonymous classes. Suggested slug: java-anonymous-class-bodies. +- **[对拍A]** Single-file vs cross-path feature drift is the structural root cause behind two of the analyst's P0s and will recur: cbm_run_java_lsp (production per-file at cbm.c:1406) and cbm_run_java_lsp_cross_with_registry share registration but not the AST enrichment passes. After the cross-file-field-types fix, extract one shared 'enrich registry from parsed AST' helper both entries call, so the next enrichment pass (records, Lombok, enum constants) cannot silently land in only one path again. +- **[对拍A]** Varargs-blind arity matching: java_lookup_method tries exact arg-count then a name-only fallback (java_lsp.c:950-959); a varargs method invoked with extra args resolves only through the weak name fallback and loses overload discrimination. CBMRegisteredFunc.min_params exists (set to -1 by both Java registrars, :3351/:3774) — populating it for spread_parameter signatures and teaching lookup_method_by_args a min_params rung is a small precision win. +- **[对拍A]** JAVA_LANG_TYPES / stdlib-table sync invariant: the auto-import table (java_lsp.c:140-188) is maintained separately from the generated registry; the stdlib-expansion proposal must add a generator-emitted java.lang name list or a test asserting every registered java.lang.* short name appears in JAVA_LANG_TYPES, or new java.lang types (ScopedValue, Thread.Builder) will register but never resolve from bare names. +- **[对拍B]** java-static-ondemand-import-calls: CBM_JAVA_IMPORT_STATIC_OD is parsed and stored (java_lsp.c:1769) but never consulted — resolve_method_call/eval_method_invocation/resolve_identifier_type check only CBM_JAVA_IMPORT_STATIC (821/1118/2021) — so `import static org.junit.jupiter.api.Assertions.*; assertEquals(...)` (likewise Mockito.when/verify, AssertJ assertThat) never resolves; in the bare-call path after exact static imports miss, try each STATIC_OD import's target class via java_lookup_method (and static fields in resolve_identifier_type). Smallest fix with the largest hit-count in any repo with tests. +- **[对拍B]** java-async-and-carrier-propagation: extend the generic machinery to the fluent shapes it skips — add CompletableFuture to propagate_template carriers and thenApply/thenAccept/thenCompose/handle/whenComplete/exceptionally to method_implies_lambda_args (stdlib rows exist return-only at java_stdlib_data.c:1185-1196); implement Map.entrySet → Set> (promised in the comment at java_lsp.c:2389, only keySet/values implemented); infer T for static collection factories List.of/Set.of/Map.of/Arrays.asList/Optional.of/Stream.of from the first argument's static type (currently bare NAMED returns, so List.of(x).get(0) → Object). +- **[对拍B]** java-user-sam-lambda-binding: JAVA_SAM_TABLE (java_lsp.c:2182-2213) is stdlib-only, so a lambda passed where the resolved method's parameter is a USER @FunctionalInterface (handler/callback/listener patterns) never binds its parameters; when find_sam misses, fall back to the registry — if the expected type is a registered is_interface with a sole registered method, use that method's patched signature param types as the SAM shape. +- **[对拍B]** java-anonymous-class-bodies: `new Runnable() { public void run() { helper(); } }` — java_resolve_calls_in_node_inner's object_creation branch (java_lsp.c:2941-2975) resolves the ctor then generic-recurses into the class body, so methods inside anonymous (and method-local) classes are walked with the OUTER enclosing class/method context and unbound parameters (process_method_decl is only reachable from java_process_class_decl); coverage suite only asserts no-crash.

Both forms are name-gated to $self/$class, preserving the zero-edge guarantee for plain functions. perl-test-ecosystem (PLAN wave 1, corrections folded): - language.c: map .t and .psgi to Perl. Note the shebang fallback already routes shebanged .cgi/.t files; this covers the common shebang-less majority (.psgi always, most t/*.t). .cgi intentionally unmapped — runnable CGI requires a shebang, which already routes it. - helpers.c cbm_is_test_file: CBM_LANG_PERL case (.t suffix, t/ and xt/ segments, language-gated). - pass_tests.c cbm_is_test_path: matching .t/t//xt/ rules (#1294 lockstep), plus a file-scope caller allowance in create_tests_edges for .t files (Perl asserts at file scope; the module-level caller name never looks like a test function). - Dropped the subtest-def half per 对拍A: no describe/it def precedent exists — JS test blocks are matched by call name in pass_tests.

charset=UTF-8 Content-Transfer-Encoding: 8bit Go (1.22-1.25): - ServeMux "METHOD /path" literals become method-qualified Route nodes with HANDLES edges on BOTH resolve venues (cbm_go_split_mux_pattern; parallel reclassify + sequential empty-resolution gate — mux.HandleFunc always resolves empty since net/http is external, adjudicated by a 6-agent duel) and the extraction handler-arg gate now accepts mux literals. - Cross-file interface method sets survive production collection (pxc_fold_go_interface_methods), turning on sole-implementer resolution (0.95) for DI-style codebases; guarded by: is_stdlib marker replacing the '/'-in-QN heuristic (sync.Pool{Get,Put} ambiguated no-go.mod repos), from_test_file gate incl. auto-created receiver entries (test doubles must not shadow the prod implementer), and a >=2-method signature requirement (single-method interfaces are structurally satisfied by any same-named method — an aliased Client{Ping} was hijacked to an unrelated Svc.Ping). - FuzzXxx functions detected as tests (native fuzzing, 1.18+). Rust (1.85-1.97 / edition 2024): - Generic-impl QN alignment: strip from impl scope QNs on the call side (extract_unified), resolver receivers, trait texts, and Phase-B2 return-type harvest — calls from generic impls now attribute to Stack.push instead of the File node, and chained calls on generic receivers keep return types. - Trait default-method bodies are walked (self dispatches through the trait), inline modules recurse (mod a { mod b { ... } }), impl-level bounds join the chalk-lite env (impl methods dispatch through the bound). Python (2.7 + 3.10-3.13): - Parameterized user-class annotations resolve: Box[T]/Repository[User] template bases are module-qualified (stdlib generics stay bare), so typed repository-pattern calls produce edges. - match/case counts toward cyclomatic complexity (Py 3.10+, mojo parity). Java (17-25): - Member lookup walks ALL supertypes breadth-first (JLS 8.4.8): extends + every superinterface for methods, fields, and the sole-implementer subtype confirmation — second-parent interface defaults and diamond hierarchies now resolve; bounded frontier with visited dedup, class chain first. Cross-cutting: UBSan null-qsort guard (pass_semantic_edges) on zero-function repos; lsp surface codec carries the tf (from_test_file) bit. Tests: +30 across route_canon/go_lsp/rust_lsp/py_lsp/java_lsp/pipeline/ extraction/language. Focused gate: 1650 passed, 1 known-red (pipeline_go_interface_skips_test_impls — full-pipeline test-double gating variant; direct-API twin passes, plumbing fix tracked in PLAN).

Shared vocabulary primer (read once, referenced everywhere) + +Every strong resolver is a thin language-specific shell over four shared abstractions. Master these before the 7 axes. + +### 0.1 `CBMType` — the type representation (`type_rep.h:9-149`) +A tagged union with **30 kinds** (`CBMTypeKind`, `type_rep.h:9-43`). The vocabulary is the ceiling on how deep any resolver can reason: +- **Universal:** `UNKNOWN`(0), `NAMED`, `POINTER`, `SLICE`, `MAP`, `FUNC`, `INTERFACE`, `STRUCT`, `BUILTIN`, `TUPLE` (multi-return), `TYPE_PARAM` (generics: `T`,`K`,`V`), `TEMPLATE` (`vector`, `Array`, `Promise`), `ALIAS`. +- **Python-flavored:** `UNION` (`A | B`, sorted-canonical, shared with TS), `LITERAL`, `PROTOCOL` (structural), `MODULE`, `CALLABLE`. +- **TS-specific:** `INTERSECTION`, `TS_LITERAL`, `INDEXED` (`T[K]`), `KEYOF`, `TYPEOF_QUERY`, `CONDITIONAL` (`T extends U ? X : Y`), `OBJECT_LIT`, `INFER`, `MAPPED`. +- **C++:** `REFERENCE`, `RVALUE_REF`. + +Constructors are arena-allocated (`cbm_type_named`, `cbm_type_template`, `cbm_type_union`, …, `type_rep.h:152-205`). The load-bearing operations for chaining are **`cbm_type_substitute`** (generic param → concrete, `type_rep.h:235`), **`cbm_type_resolve_alias`** (16-level cycle-guarded, `:230`), and **`cbm_type_deref`/`cbm_type_elem`** (`:208-209`). + +### 0.2 `CBMTypeRegistry` — cross-file symbol store (`type_registry.h:87-155`) +Two arrays (`funcs`, `types`) + lazy hash indexes (`cbm_registry_finalize`, `:165`). Key excellence properties: +- **`CBMRegisteredFunc`** (`:29-43`) carries `receiver_type` (NULL ⇒ free function; non-NULL ⇒ method on a type — *this is what makes OO chains resolve*), `signature` (a `FUNC` `CBMType` with real param+return types — *this is what makes `.b().c()` chains resolve*), `type_param_names`, `flags` (`CBM_FUNC_FLAG_*`), `impl_trait_qn` (Rust). +- **`CBMRegisteredType`** (`:46-76`) carries `field_names/field_types`, `method_names/method_qns`, `embedded_types` (base/embedded QNs), `alias_of`, `type_param_names`, `is_interface`, `is_stdlib`, `from_test_file`, plus TS `call_signature`/`index_*`. +- **Tier-2 chaining:** `fallback` pointer (`:98-103`) — a small per-file overlay registry chains to a shared immutable base. **`read_only`** seal (`:146-154`) — set at finalize; `cbm_registry_add_*` hard-return on a sealed registry. This is both a correctness (no data race across parallel workers) and perf (no post-finalize linear-scan tail) invariant. +- **Overload-aware lookups:** `cbm_registry_lookup_method_by_types` (scores overloads by arg-type match, `:225`), `_by_args` (`:214`), `_lookup_method_aliased` (`:208`), plus allocation-free auxiliary iterators (`CBMMethodIter`, `CBMTypeShortIter`, `CBMFreeFuncIter`, `:248-311`). + +### 0.3 `CBMScope` — lexical binding frames (`scope.h:9-95`, `scope.c`) +Chunked (`CBM_SCOPE_CHUNK_BINDINGS 16`) parent-linked frames, arena-owned. Beyond ordinary `type`, each binding carries a **`callable_qn`** identity (`scope.h:16`) — the exact QN of a callable value the binding references, kept *separate from* the CBMType so `const f = foo; f()` resolves `f→foo`. Two disciplines matter: +- **Fail-closed binds:** `cbm_scope_bind_checked`/`_bind_callable_checked` return `false` on arena exhaustion (`scope.c:77-89`). The void forms discard that — and a caller who then does a *chain* lookup would see a **parent** binding of the same name and fabricate a shadow that never took effect (`scope.h:70-83`). Callable-proof paths must use the checked form and read the local result. +- **Shadow-correct callable lookup:** `cbm_scope_lookup_callable` returns NULL when a nearer *ordinary* binding shadows a parent's callable (`scope.c:123-137`) — reassignment fails closed instead of leaking a stale alias. + +### 0.4 Depth/step caps (the perf-sacred constants) +- `CBM_LSP_MAX_LOOKUP_DEPTH 16` (`scope.h:36`) — alias/MRO/embedded-field traversal bail-to-UNKNOWN. +- `CBM_LSP_MAX_WALK_DEPTH 512` (`scope.h:45`) + `cbm_lsp_max_walk_depth()` (`scope.h:55-65`, env-overridable, relaxed-atomic cached — never `getenv` on the hot path). +- Per-resolver eval caps: see §1 and §5. + +### 0.5 The emission surface — `CBMResolvedCall` (`cbm.h:392-402`) +Every resolver's *only* output is a push of `{caller_qn, callee_qn, strategy, confidence, reason, kind, site bytes, source_origin}`. `kind` is `CBM_RESOLVED_INVOCATION` (a CALLS edge) or `CBM_RESOLVED_CALL_REFERENCE` (an explicit callable reference, e.g. passing `foo` by name). See §4. + +### 0.6 The `CBMLSPDef` surface — cross-file def interchange (`lsp_surface.c`) +The serialized per-file def record that feeds Tier-2 registries. Fields (codec at `lsp_surface.c:87-104`): `qualified_name`, `short_name`, `label`, `receiver_type`, `def_module_qn`, `return_types`, `embedded_types` (pipe-joined), `field_defs` (`"name:type|name:type"`), `method_names_str`, `signature_param_types[]`, `is_interface`, `lang`, `namespace_name`, `trait_qn`, `is_rust_impl_relation`, `is_abstract`, `from_test_file`, `decorators[]`.

Found by measuring the production binary on a real 274-file Mojolicious checkout. Three fixes: 1. `use Mojo::Base 'Parent'` — the dominant modern Perl inheritance idiom — was not recognized as establishing @ISA. module_name was "Mojo::Base", so it fell through to Exporter-import handling and the parent class string was treated as an import, never a parent. Now handled like `use parent`: quoted string -> @ISA parent, `-base` -> inherits Mojo::Base itself, other flags (-role/-strict/-signatures/...) contribute nothing. 2. Parent classes are now emitted as import rows in extraction (perl_collect_inheritance_imports): `use parent/base/Mojo::Base 'Base'` each perform a compile-time `require` of the parent, so an IMPORTS edge to the parent is correct — and it lets the cross-file LSP def filter keep the parent module's defs (an @ISA parent is a cross-file dependency but not previously an import, so its defs were filtered out and inherited calls could never resolve). This is a targeted alternative to exempting Perl from the filter entirely, which was measured to regress the real repo by widening same-name ambiguity. 3. The cross-file LSP registered an @ISA parent as a bare type with no method table (the parent's subs live in another file). cbm_run_perl_lsp_cross now attaches each resolved ISA parent's cross-file Function/Method defs to the parent type, so `$self->inherited` (self typed to a child package) dispatches up the ISA chain to the parent's cross-file sub. Resolves one level of cross-file inheritance.

This walks the full @ISA chain across files. Design is Perl-isolated (no changes to shared cross-language passes), following an adversarial review that rejected the base_classes/embedded_types route (Module defs are dropped before that join; no per-package Perl def exists; the Perl registrar never reads embedded_types; and it would mint cross-language false INHERITS edges via short-name base resolution): - CBMFileResult.perl_isa_parents (cbm.h): a file's TAGGED @ISA parent spellings, collected in extract_imports.c ONLY from use parent/base/Mojo::Base statements. An ordinary `use Foo` never appears here (zero-edge guarantee). - CBMPerlInheritIndex (pass_lsp_cross.h): a project-wide module_qn -> [parent module_qns] map built in pipeline.c from the per-file caches, threaded into cbm_run_perl_lsp_cross, freed after cbm_parallel_resolve returns. - Bounded worklist chain-walk (perl_lsp.c cbm_run_perl_lsp_cross): BFS over ancestors (PERL_CHAIN_CAP=256 + seen dedup). Each ancestor is resolved over the full all_defs, its subs attached to its type, its own tagged parents pushed, and its type's embedded_types seeded so perl_lookup_method's existing recursion walks the rest. Realloc-safe: the type is re-found by name AFTER perl_type_set_methods (which may realloc reg.types) before embedded_types is set. Validated on scratchpad/probe3lvl (Dog -> Animal -> Base, one class per file): the grandparent edge Dog.bark -> Base.root_method now resolves alongside the immediate-parent Dog.bark -> Animal.speak. Unit test: perllsp_cross_multilevel_inherited_method. The cbm_pxc_run_one signature gained the index parameter; test_py_lsp.c and test_rust_lsp.c call sites updated. Known v1 limitation: parent spellings are collected per file, so a rare multi-package file over-approximates; Perl is ~one package per file in practice. See docs/lsp-uplift/PERL-CROSS-FILE-INHERITANCE.md for the full design, the adversarial-review course-corrections, and the measurement harness.

The Perl registrar never reads `CBMLSPDef.embedded_types` anyway. + +Plus a **cross-language false-edge** hazard: `pass_semantic` resolves bases by +short name with no language scoping, so a Perl `use parent 'Animal'` plus any +Python `class Animal` would mint a bogus INHERITS edge. And a **use-after-realloc** +footgun in a naive chain-walk (`cbm_registry_add_type` reallocs `reg.types`). + +### The approved, Perl-isolated design (implemented here) + +Zero changes to shared, cross-language passes (`pass_semantic`, `pxc_map_label`, +extraction `base_classes`): + +- **`CBMFileResult.perl_isa_parents`** (`cbm.h`): a file's TAGGED `@ISA` parent + spellings, collected in `extract_imports.c` **only** from inheritance `use` + statements — an ordinary `use Foo` never appears here (zero-edge guarantee). +- **`CBMPerlInheritIndex`** (`pass_lsp_cross.h`): a project-wide + `module_qn → [parent module_qns]` map assembled in `pipeline.c` + (`cbm_perl_build_inherit_index`) from the per-file caches, threaded into + `cbm_run_perl_lsp_cross`, and freed after `cbm_parallel_resolve` returns. +- **Bounded worklist chain-walk** (`perl_lsp.c` `cbm_run_perl_lsp_cross`): BFS + over ancestors (`PERL_CHAIN_CAP=256`, `seen` dedup). For each ancestor: resolve + to a module over the FULL `all_defs`, attach its Function/Method defs to its + type, look up *its* tagged parents in the index (push unseen), and seed the + ancestor type's `embedded_types` so the existing `perl_lookup_method` recursion + walks the rest of the chain. +- **Realloc-safe**: `perl_type_set_methods` (which may realloc `reg.types`) is + called first, then the type is **re-found by name** before its `embedded_types` + is written — never a pointer held across the realloc. + +### Validation + +`scratchpad/probe3lvl` — three files `Dog → Animal → Base`, where `Dog::bark` +calls both `$self->speak` (immediate parent Animal) and `$self->root_method` +(grandparent Base). Baseline binary resolved only the immediate-parent edge; the +multi-level binary resolves **both** on a fresh path: + +``` +

.lib.Dog.bark ->

.lib.Animal.speak # immediate parent +

.lib.Dog.bark ->

.lib.Base.root_method # grandparent (multi-level) +``` + +Unit test: `perllsp_cross_multilevel_inherited_method` (in `test_perl_lsp.c`). + +### Known v1 limitation + +`perl_isa_parents` is collected per *file*, not per *package*, so a rare +multi-package file (`package A; use parent 'X'; package B; use parent 'Y';`) +over-approximates (A may see Y). Perl is ~one package per file in practice +(all of Mojolicious), so this is acceptable; per-package tagging is a follow-up. + +--- + +## 4. Measurement harness (reusable) + +1. **Fresh path every time** — `cp -r `; index ``; the + daemon cache keys on path and will otherwise serve a stale graph. +2. **`get_graph_schema` for edge/label histograms**, not Cypher. +3. **Minimal probes are unrepresentative** — a single-file Rust chain gave 0 + CALLS; real-repo CALLS are internal-call-dominated. Validate mechanisms with + small cross-file probes, but judge impact on a real repo. +4. **`ASAN_OPTIONS=detect_leaks=0`** for CLI queries against sanitized builds. +5. Build discipline: `test-focused` is ONE giant `cc` reading ALL sources — never + edit a source file while it runs. Launch long builds detached + (`setsid … ; echo MARK_EXIT:$? >> log`) so they survive session teardown. + +--- + +## 5. Session-continuity note + +The multi-level implementation was produced in an isolated git worktree that was +terminated mid-run by an auth expiry while it was still adding debug +instrumentation. Recovery: the worktree diff was reviewed against the adversarial +findings, three `fopen("/tmp/ml_dbg.txt")` debug blocks were removed from +`perl_lsp.c`, the grandparent edge was re-validated on `probe3lvl`, and the +focused suites were re-run before merge. Uncommitted scratch directories +(`mojo_ml/`, `pbig*/`, `pf_*/`, `*.txt` query dumps) are build/measurement +artifacts and are not committed. diff --git a/internal/cbm/cbm.h b/internal/cbm/cbm.h index 256826947..81af6ccd6 100644 --- a/internal/cbm/cbm.h +++ b/internal/cbm/cbm.h @@ -524,6 +524,11 @@ typedef struct CBMFileResult { const char **constants; // NULL-terminated (NULL if none) const char **global_vars; // NULL-terminated (NULL if none) const char **macros; // NULL-terminated, C/C++ only (NULL if none) + const char **perl_isa_parents; // Perl: TAGGED @ISA parent spellings from use + // parent/base/Mojo::Base (NULL-terminated, NULL + // if none).

On a real 274-file Mojolicious index ALL of these were silently dropped — 0 perl_method_* edges — even though the exact same files, split small enough to take the SEQUENTIAL resolver, produced them fine (104 perl_method_inherited on a 68-file subset before this fix's twin path was reached). Root cause is a sequential/parallel parity gap in the #476 Perl noise guard (cbm_perl_suppress_generic_match). The guard drops weak short-name method matches (suffix_match / unique_name) — correct — but its keep-list was only same_module / import_map / import_map_suffix. The SEQUENTIAL resolver (pass_calls.c) emits an LSP-resolved edge and returns BEFORE reaching the guard, so its perl_method_* edges never hit it. The PARALLEL resolver (pass_parallel.c, which any repo large enough takes) sets res.strategy = the LSP strategy and falls THROUGH to the guard, which — not recognizing perl_method_inherited et al. — dropped every one. Small repos kept the edges; large repos lost them all. Fix: the guard keeps any `perl_`-prefixed strategy. Those come only from the Perl LSP's confident, receiver-typed/exact resolutions (zero-edge guarantee); the registry's weak guesses spell suffix_match / unique_name / qualified_suffix and are still dropped. No-op on the sequential path (never sees a perl_ strategy there); restores the edges on the parallel path. Real-repo impact (Mojolicious, 274 files, fresh index): CALLS 2600 -> 3331 (+731, +28%): +715 perl_method_inherited, +29 perl_method_super. Sampled edges all correct — LoginApp::Controller::Login::index -> Mojolicious::Controller render/param/session (inherited controller methods), Mojo::Asset::Memory::add_chunk -> Mojo::EventEmitter::emit (2-level @ISA), Mojo::Asset::File::contains -> Mojo::Asset start_range/end_range. With the has-accessor emission (9a11e4ea) the campaign total is 2216 -> 3331 (+1115, +50%) from the original baseline. Adds regression coverage: cbm_perl_suppress_generic_match keeps perl_method_* (test_registry.c) and cross-file inherited dispatch under the real-Mojolicious def shape — deep path QNs, `::`-parent, has-accessor target, and the parent present only in all_defs (the filtered per-file `defs` excludes it) — (test_perl_lsp.c).

The Perl LSP left enclosing_func_qn NULL while walking those top-level statements, so perl_emit_resolved dropped EVERY typed top-level call: a 109-file Mojolicious test suite with ~12k `$var->method` sites emitted almost no CALLS edges. The unified extractor ALREADY attributes top-level raw call rows to the file module (extract_unified.c: enclosing_func_qn = module_qn when there is no enclosing sub). The LSP just didn't match it — so its typed resolution had a NULL caller and never bound to the module source node. Fix: in perl_lsp_process_file PASS 2, set enclosing_func_qn = module_qn for the top-level-statement branch (save/restore around the walk), exactly mirroring the extractor. Anonymous route/hook callbacks (`sub ($c) {...}`) inherit it too (process_subroutine keeps the caller for a name-less sub), so their calls attribute to the module as well.

Now that top-level statements carry a caller QN (previous commit), these calls can finally land an edge — they just needed a receiver type. perl_bind_routing_controller_param binds a signature param named `$c` to Mojolicious::Controller, DOUBLE-GATED on (a) the enclosing call being a Mojolicious routing/hook DSL method (get/post/under/to/hook/websocket/group/...) and (b) the `$c` convention name — zero false positives. The class is seeded into the cross pass's @ISA chain-walk (only when the file has such a callback) so its method table (render/stash/param/... + its own Mojo::Base parent) attaches from all_defs and dispatch works. Real-repo impact (Mojolicious, 274 files, fresh index): CALLS 3816 -> 3827 (+11), all correct — examples/chat -> Mojolicious::Controller on/send, examples/responses -> render/write_sse/finish, t/mojolicious/app -> req/res/finish/on/send, t/mojolicious/signatures_lite_app -> render. The gain is modest because Mojolicious's own test suite mostly drives Test::Mojo ($t->get_ok, already resolved by the top-level-caller commit) rather than `sub ($c)` route handlers (~5 real files; the rest of the `$c->render` grep hits are POD examples), but every edge is a genuine controller-method call. Adds regression tests: top-level module-caller attribution ($t->get_ok on a Test::Mojo resolves with the file module as caller) and the routing-$c typing (get => sub ($c){ $c->render } resolves to Mojolicious::Controller::render).

The lowercase bareword `curfile` before `->` is a FUNCTION CALL, not a class name — but two independent gaps dropped every such edge on real repos: 1. EXTRACTION (extract_calls.c): a method_call_expression emits ONE call row, for the METHOD (`sibling`). The bareword receiver `curfile` produced no call row, so the graph had no site for an edge to the curfile function. Fix: for a Perl method call whose invocant is a LOWERCASE bareword (Perl spells classes CamelCase, functions lowercase), emit a second call row for the invocant at its own span, flagged requires_lsp_resolution so a textual short-name fallback can never bind it to an unrelated same-named sub (a non-imported bareword stays zero-edge). 2. RESOLUTION (perl_lsp.c): perl_resolve_method_call treated every bareword invocant as a class (`perl_resolve_package_name`). Fix: when the lowercase bareword is an Exporter import (perl_find_import → registry func), emit the call edge to that function (perl_imported_function) and type the receiver from the function's return type so a proper `sub { Class->new }` return can dispatch the chained method. Mirrored in perl_eval_method_call_type for typing inside larger expressions. The two are coupled: LSP resolved edges are site-matched against extracted call rows (site span + callee short name) in the parallel resolver, so the LSP edge survives only when extraction recorded a matching call row — which is why the resolver change alone produced zero edges until extraction emitted the receiver call row.

COLON/DOT MISMATCH. perl_infer_return_types stores a class's return-type spelling DOTTED ("Mojo.File", `::`→`.`), but the cross-file used-module type table is keyed by the module name AS WRITTEN in `use` (colons, "Mojo::File") and cbm_registry_lookup_type is exact-match — so a multi-segment dotted return type never finds its method table. A single-segment class ("Widget", dot==colon) masked this in fixtures. Fix: perl_class_qn_colon_variant + a retry at both typed-receiver lookup sites (perl_resolve_method_call, perl_eval_method_call_type) — when the dotted lookup misses, try the colon spelling. 2. __PACKAGE__ FACTORY RETURN. `sub curfile { __PACKAGE__->new(...) }` (Mojo::File) returns its own package, but (a) tree-sitter-perl parses `__PACKAGE__` as a func0op_call_expression, not a bareword, so perl_infer_return_types rejected it → no return type; and (b) even with the type inferred, "__PACKAGE__" is not a real class name. Fix: accept the __PACKAGE__ macro invocant in perl_infer_return_types (extract_defs.c), and perl_func_return_class_qn maps the literal "__PACKAGE__" back to impf's own package, reverse-looked-up through the xmod map to the colon-spelled module name the used-module type is keyed by. So `curfile->sibling` now types the receiver to Mojo::File and dispatches sibling/dirname/child/list/is_abs. Real-repo impact (Mojolicious, fresh index): CALLS 4229 -> 4272 (+43), all correct — the colon/dot fix unlocked +3 multi-segment accessor chains (perl_method_inherited), and the __PACKAGE__ curfile chain added +40 edges to Mojo::File methods (29 sibling, 5 dirname, child/is_abs/list/list_tree) from every module/test doing `curfile->sibling(...)` (Renderer, Static, IOLoop::TLS, ~24 test files); zero spurious (all target Mojo::File::).

Mojo::File's `path` uses the same idiom — `sub path { __PACKAGE__->new(@_) }` — but is called as a FUNCTION, `path(@parts)->child(...)`, whose receiver is a function_call_expression routed through perl_eval_function_call_type. That path returned the raw literal "__PACKAGE__" type, so the chained method never dispatched (path(...)->child / ->to_string / ->list_tree / ->extname all failed). Fix: in perl_eval_function_call_type, run the resolved function's return type through perl_func_return_class_qn — mapping "__PACKAGE__" back to the function's own package (xmod reverse-lookup to the colon-spelled used-module type key), and passing every other spelling through unchanged. So a `func(...)->method` chain on any `__PACKAGE__->new` factory now types its receiver.

Implementation (cbm_run_perl_lsp_cross, before the @ISA chain-walk): collect `$self->M1->M2` usage per file, and for each of the file's OWN untyped methods M1 whose usage set has >= 3 distinct non-universal methods, find the UNIQUE base-most class K (drop any coverer that is a descendant of another) that defines them all; set M1's return type = K and seed K into the chain-walk so its method table + @ISA attach. Strictly gated so ambiguity stays zero-edge: UNIVERSAL/Mojo::Base methods (new/isa/can/tap/attr/...) are excluded from the signature, and a non-unique or self match yields nothing — preserving the correct-edge guarantee. Correctness (verified, 5/5 sound on Mojolicious): the ONLY inferences made are Mojo::IOLoop::Client::reactor->Mojo::Reactor, Mojo::Server::Daemon::ioloop-> Mojo::IOLoop, Mojolicious::Controller::app->Mojolicious, Mojolicious::Controller::res->Mojo::Message::Response, and Test::Mojo::ua->Mojo::UserAgent — each genuinely returns that class. The POLYMORPHIC accessors are correctly REJECTED: Test::Mojo/Controller `tx` is used as both HTTP and WebSocket transactions (its method-set res/error/send/finish/ is_websocket is covered by no single class), so it stays zero-edge rather than fabricating wrong edges.

Files processed BEFORE that file never saw the inferred type, so cross-file accessor chains (`$c->app->routes`, `$c->res->code`) stayed unresolved even when the accessor WAS correctly inferred. Root cause is processing order, not arena lifetime (K is a persistent def_module_qn string). Fix: a dedicated pre-pass (cbm_perl_duck_prepass) runs BEFORE the parallel resolve loop. Phase 1 walks every Perl file's AST collecting `$self`/`$class` accessor chains and aggregates each accessor's method-set GLOBALLY (persistent arena), attributing each accessor to its defining-class def via own-def or @ISA (perl_duck_find_accessor_def). Phase 2 runs the SAME base-most-unique gate as the per-file block (union own-definers -> coverers via perl_duck_class_defines -> unique base-most survivor via perl_duck_is_a; base_n==1 && K!=own_mod && >=PERL_DUCK_MIN distinct methods) and writes the inferred return type into all_defs up front. The existing return-type-class @ISA seeding then dispatches the chains in every file regardless of processing order. Wired into the PARALLEL pipeline (pipeline.c -> run_parallel_pipeline, after perl_inherit is built, before cbm_parallel_resolve) via a shared driver (cbm_pxc_perl_duck_prepass_driver) that gathers each Perl file's source + module QN + cached tree. The sequential pass_lsp_cross path calls the same driver. (A first cut wired only the sequential path and measured +0 because index_repository runs the parallel pipeline.) Real-repo impact (Mojolicious, fresh index): CALLS 4606 -> 4660 (+54, +51 unique), all perl_method_inherited, all correct: ua -> Mojo::UserAgent (max_redirects/build_tx/cookie_jar/request_timeout/...), app -> Mojolicious (plugins/types/routes/renderer/moniker/home/mode/log/start), server -> Mojo::Server::Daemon (max_accepts/acceptor/max_connections), res -> Mojo::Message::Response (code/headers/content/body). Campaign 2216 -> 4660 (+2444, +110%). Soundness preserved: the polymorphic `tx` accessor (WebSocket-only `send` plus base Transaction methods, covered by no single class) yields base_n != 1 and stays zero-edge; the ~1069 `$tx->req`/`$tx->res` sites stay unresolved because typing an arbitrary `$tx` local is genuinely unsound. No hardcoded class tables. Gate: 472 passed / 0 failed; perllsp_cross_duck_typed_accessor still passes.

New: docs/lsp-uplift/PERL-DUCK-TYPING-AND-CROSS-LANG-AUDIT.md - The shipped ladder (site-attachment invariant, colon/dot reconcile, @ISA-on-used-modules +173, per-file duck-typing +15, cross-file pre-pass +54). - Duck-typing mechanism + the base-most-unique soundness gate (why polymorphic `tx` correctly stays zero-edge). - The cross-file pre-pass processing-order root cause + the parallel-pipeline wiring gotcha (sequential-only wiring measured +0). - Four-language audit: Java(gson) 9545, Rust(ripgrep) 6690, Python(Django) 62084 / (Flask) 1408, Perl 4660 -- all mature; the ~40% low-conf heuristic tail is external/stdlib by construction (candidate_count_penalty floors conf by design). No additive coverage lever remains. - Every dead-end built/measured/reverted (invocant-name +0, per-scope local-var +5-reverted, $tx +0 with the regex-overcount lesson) so the next iteration does not re-walk them. - Measurement pitfalls: fresh cp -r (incremental cache), RETURN r overflow on 62k edges, temp-daemon full-env requirement, bare-callee spelling. - The standing precedent: engine soundness > marginal edge count. Updated: docs/lsp-uplift/PLAN.md - Retro at top + perl-cross-file-lsp marked done through daaf538c.

If extraction never emitted a call row for the site, the +LSP edge is dropped on the floor — silently. + +Consequence: several "resolver" fixes are really *extraction* fixes. E.g. +`curfile->child` (`7f588ab3`): the resolver could type `curfile`'s return, but +extraction emitted no call row for the lowercase-bareword invocant, so there was +nothing to attach to. Fix = emit a second call row with +`requires_lsp_resolution=true` (which makes it resolve **only** via LSP — no +textual fallback, so it is zero-edge-safe when the LSP misses). + +**Debugging tip.** When a receiver types correctly in a unit test but produces +no edge on the real repo, suspect site-attachment first: grep the extracted call +rows for the site before touching the resolver. + +### 2.1 Colon vs dot spelling (the multi-segment trap) + +Used-module types are keyed **colon** (`"Mojo::File"`, as written in `use`). +Return types are stored **dotted** (`"Mojo.File"`, `::`→`.` via +`perl_infer_return_types`). `cbm_registry_lookup_type` is **exact-match**, so a +multi-segment dotted return type never finds its colon-keyed method table. A +single-segment class (`Widget`, where dot==colon) masks this in fixtures — it +only bites on real multi-segment chains. Fix: `perl_class_qn_colon_variant` + +a retry at both typed-receiver lookup sites. + +--- + +## 3. Structural (duck) typing — inferring a typeless accessor's class + +Mojo::Base accessors declared `has 'tx'` (no default) have **no static return +type**. `$self->tx->res->finish` therefore dangled. Duck-typing recovers the +type from *how the accessor's result is used*: + +> For an untyped accessor `M1`, collect the set of methods called on +> `$self->M1->{...}`. Find the unique in-repo class whose own+inherited method +> table covers **all** of them; require ≥ `PERL_DUCK_MIN` (=3) distinct +> non-universal methods; reduce covering classes to the **base-most** one; if +> exactly one survives (and it isn't the accessor's own module), that is `M1`'s +> return type. + +Key helpers (`internal/cbm/lsp/perl_lsp.c`): `perl_duck_is_universal` (excludes +`new`/`isa`/`can`/`tap`/`to_string`/…), `perl_duck_class_defines` (own + @ISA +presence, bounded DFS), `perl_duck_is_a` (descendant check for base-most +reduction), `perl_duck_collect` (walks the AST for `$self->M1->M2`). + +**Soundness is the whole point.** The gate is intentionally strict: +- `base_n != 1` (ambiguous) ⇒ zero-edge. +- The canonical rejection is **`tx` itself**: it is polymorphic (HTTP vs + WebSocket transaction); its usage set spans base-`Mojo::Transaction` methods + **plus** WebSocket-only `send`/`is_websocket`, which **no single class** + covers ⇒ `base_n != 1` ⇒ correctly stays zero-edge. Typing `tx`→WebSocket + would fabricate `send` on HTTP transactions. The gate refusing here is the + correct-edge guarantee working, not a miss. + +Per-file duck-typing (`dadaff3b`) inferred 5 accessors correctly (reactor, +ioloop, Controller::app, Controller::res, Test::Mojo::ua) for +15. + +--- + +## 4. The cross-file pre-pass (`daaf538c`, +54) — a processing-order bug + +`dadaff3b` wrote the inferred type into `all_defs[i].return_types` **as a side +effect during the accessor's own file's resolution** (guarded by +`def_module_qn == module_qn`). `cbm_run_perl_lsp_cross` runs **per file** in a +loop (`src/pipeline/pass_lsp_cross.c`; `all_defs` is built once by +`cbm_pxc_collect_all_defs` into a persistent arena). So any file resolved +**before** the accessor's own file never saw the inferred type — e.g. +`Controller::res`→Response was correctly inferred while processing +`Controller.pm`, but the action/test files using `$c->res->code` were resolved +earlier and got nothing. Root cause is **processing order**, not arena lifetime +(the written string `K` is a persistent `def_module_qn`, not scratch). + +**Fix:** `cbm_perl_duck_prepass` runs *before* the resolve loop. Phase 1 +aggregates `$self`/`$class` accessor-chain method-sets **globally** across all +files (persistent arena), attributing each accessor to its defining-class def +(own or @ISA, via `perl_duck_find_accessor_def`). Phase 2 runs the same +base-most-unique gate and writes return types up front. The existing +return-type-class @ISA seeding then dispatches every file's chains regardless of +order. + +> **Critical wiring gotcha.** `index_repository` runs the **parallel** pipeline +> (`src/pipeline/pipeline.c` → `run_parallel_pipeline` → `cbm_parallel_resolve`), +> **not** the sequential `pass_lsp_cross` path.

The four-language real-repo audit (the GAP answer) + +Before assuming "more Perl edges" was the goal, we measured **all four axes** on +real repos for the first time (fresh index; `CALLS`): + +| axis | real repo | files | CALLS | notes | +|---|---|---|---|---| +| Java | gson | 264 | 9545 | rich LSP (`lsp_type_dispatch` 2636, `lsp_constructor_synth` 978…) — mature | +| Rust | ripgrep | 110 | 6690 | `suffix_match` 2715 (40 %) — heuristic-heavy | +| Python | Django | 2930 | 62084 | 22026 edges ≥ 0.9 conf; `lsp_method` 10830 — mature | +| Python | Flask | 83 | 1408 | = 794 resolved + 614 Flask-route edges (`callee/url_path/via` — a distinct route-edge category, not unresolved calls) | +| Perl | Mojolicious | ~274 | 4660 | this campaign | + +**The load-bearing finding:** on every axis, the low-confidence heuristic edges +(`suffix_match` / `unique_name`, ~40 % of Django/Rust) are **external/stdlib +calls with no in-repo target** — sampled: Django `os.environ.get` (52 +candidates, conf 0.02), `threading.Event`; ripgrep `std::env::current_dir`, +`io::Error::new`, `.push`, `.iter()`; gson `delegate.read` (49 candidates — +genuinely polymorphic), `.equals`/`.get`/`.put` (java.util). These are not +under-resolved in-repo calls; they have no in-repo target and cannot be soundly +resolved to one. `candidate_count_penalty` (`src/pipeline/registry.c`) +**deliberately** floors their confidence to ~3/count — the engine's design is +high-recall emission + confidence tagging, consumers threshold. So there is **no +additive coverage lever** on Java/Rust/Python: the unresolved tail is external +by construction. + +### Measurement pitfalls hit during the audit (write these down) + +- **`query_graph … RETURN r` overflows** on a 62k-edge result (daemon-backed CLI + fails). Use `RETURN count(r)`, and `WHERE r.strategy='X' RETURN count(r)` / + `WHERE r.confidence < 0.5 …` for breakdowns. +- **Restricted env breaks the temp-daemon spawn.** The CLI spawns a temporary + daemon from `/proc/self/exe`; a stripped `env={PATH,ASAN_OPTIONS}` makes it + fail.

Dead-ends built, measured, and reverted (do not re-walk) + +Each was implemented cleanly and measured on real Mojolicious; each is kept out +of `main` for the stated reason. + +### 6.1 Invocant-name extension → +0 +Treat the enclosing sub's invocant (any name, e.g. `$c`, not just literal +`$self`/`$class`) as self-equivalent in `perl_duck_collect`. **+0** on the +framework source: Mojolicious's own lib/tests barely contain controller-*subclass* +actions (`package X; use Mojo::Base 'Mojolicious::Controller'; sub act { my +$c=shift; $c->req->… }`) — that pattern is **user-app** code. The framework's +`$c->req` chains live in `main`/test callbacks where `$c` is a controller +*passed into* the callback, not the enclosing sub's invocant, so attribution +correctly fails. + +### 6.2 Per-scope local-variable duck-typing → +5, reverted +Type an untyped local `$c` from its per-scope method-set (same gate). Built +clean, gate 472/0, edges correct-on-Mojolicious — **but reverted.** A guarded +debug probe (1421 bind attempts logged) proved the gate **fires correctly** +(`$c`→Controller, `$t`→Test::Mojo, `$renderer`→Renderer…) yet **every qualifying +local is already typed** by existing assignment/invocant/routing inference, so +the sound mechanism nets 0. The measured +5 came only from a class-seed +activating the pre-existing blanket `my $c=shift`→Controller binding — i.e. the +gain was **not sound-by-construction** (it leans on a binding that could mistype +`$c` in a non-Mojo repo). Held out on discipline grounds. + +### 6.3 `$tx`→Mojo::Transaction per-scope → +0 (and a measurement lesson) +The `$tx->req`/`$tx->res` chains (648 + 421 sites) are the largest unresolved +block. A `grep`/`sub`-split estimate suggested "37 scopes" where a +Transaction-*distinctive* method (`connection`/`keep_alive`/`result`/… — none on +Controller) would uniquely type `$tx`→Mojo::Transaction. **The estimate was a +regex artifact** (crude sub-splitting + POD examples). Real tree-sitter `$tx` +scopes carry only ~2 distinct methods (`{kept_alive,res}`, `{on,send}`, …) — +below `PERL_DUCK_MIN` — and `$tx` is already typed where it clears. **+0.** +**Lesson: validate scope counts with the real parser, never a line-regex.** + +### 6.4 Why the big chains are structurally unresolvable +`$tx` is sourced from typeless / statically-invisible producers: `$t->tx` (104), +`$ua->get`/`post`/… (monkey-patched, ~50), `$self->tx` (typeless accessor); only +`Mojo::Transaction::HTTP->new` (16, already resolved) and `build_tx` (~29, needs +intra-sub return-var tracking, previously 0-yield) are typed sources. Closing +the rest would require either unsound receiver assumptions or resolving +monkey-patched methods — both violate the correct-edge guarantee. + +--- + +## 7. Conclusion & the standing discipline + +The sound **additive** frontier is exhausted at 4660 (+110%). Remaining +unresolved edges are a **structural limit of sound static analysis** — typeless +polymorphic accessors (`tx`), monkey-patched methods (`$ua->get`), polymorphic +dispatch (gson `delegate.read` across 49 impls) — not missing features.
