issue832_rss.py -- direct RSS reproduction for #832 (NON-GATING, manual repro tier).
WHY THIS IS NOT A C UNIT TEST
-----------------------------
The RSS ratchet is a property of mimalloc v3's abandoned-page handling
(page_reclaim_on_free=0): pages a worker THREAD abandons at exit are not
reclaimed when the main thread later frees their blocks. That only manifests in
the PROD binary, which links mimalloc as the global allocator (Makefile.cbm:
MI_OVERRIDE=1). The C test-runner and the C repro-runner are built CRT+ASan
(MI_OVERRIDE=0), so mimalloc is inert there and cbm_mem_rss() falls back to
os_rss() -- a C test would be VACUOUS. Hence this drives the real
`build/c/codebase-memory-mcp` server over stdio and samples its RSS from `ps`.
WHAT IT SHOWS
-------------
A long-lived MCP server is driven through K index_repository cycles of the same
fixture. The in-process pipeline (CBM_INDEX_SUPERVISOR=0) is the pre-#832-fix
background-path behaviour: RSS RATCHETS across cycles. The supervised subprocess
path (default) is the fix: each child returns 100% of its RSS on exit, so the
long-lived parent stays ~FLAT. The auto-index (mcp.c) and watcher re-index
(main.c) paths now route through that same supervised subprocess, so they inherit
this flat profile; the deterministic routing proof is the GATING guard
tests/test_mcp.c::index_bg_paths_route_through_supervisor_issue832.
Inherently noisy (allocator/OS dependent) -> thresholds are generous and this is
NOT wired into `make test` / `ci-ok`. Run manually:
make -f Makefile.cbm cbm

* repro_grammar_config.c -- Per-grammar INVARIANT battery for the
* CONFIG / DATA language family.
*
* One TEST() per language so per-language RED/GREEN shows on the bug-repro
* board. Each test runs a battery adapted to what the language actually models:
* most config/data languages are STRUCTURAL-ONLY (no func_types or call_types).
* The battery dimensions applied per language are documented in the per-TEST
* comment.
*
* Languages covered (16) and the CBM_LANG_* enum each uses (all verified in
* internal/cbm/cbm.h):
* JSON -> CBM_LANG_JSON
* JSON5 -> CBM_LANG_JSON5
* YAML -> CBM_LANG_YAML
* TOML -> CBM_LANG_TOML
* INI -> CBM_LANG_INI
* HCL -> CBM_LANG_HCL
* XML -> CBM_LANG_XML
* CSV -> CBM_LANG_CSV
* PROPERTIES -> CBM_LANG_PROPERTIES
* DOTENV -> CBM_LANG_DOTENV
* KDL -> CBM_LANG_KDL
* RON -> CBM_LANG_RON
* PKL -> CBM_LANG_PKL
* NICKEL -> CBM_LANG_NICKEL
* JSONNET -> CBM_LANG_JSONNET
* STARLARK -> CBM_LANG_STARLARK
*
* BATTERY DIMENSIONS
* ------------------
* SINGLE-FILE (cbm_extract_file, via inv_rx + inv_count_* helpers):
* 1. extract-clean : inv_extract_clean(src,lang,file) == 1
* (parser returned a result and did not set has_error).
* 2. labels-valid : inv_count_bad_labels(r) == 0
* (every extracted def label is in the known label set).
* 3. fqn-wellformed : inv_count_bad_fqns(r) == 0
* (no empty / ".." / leading or trailing '.' / whitespace QNs).
* 4. ranges-valid : inv_count_bad_ranges(r) == 0
* (start_line >= 1 and start_line <= end_line).
* 5. defs-present : at least one def with the expected label is extracted.
* SKIPPED for languages whose spec has no func_types,
* class_types, or meaningful var_types that produce
* extractable defs (JSON, JSON5, CSV, KDL, RON, DOTENV).
* 6. calls-extracted : inv_has_call(r, callee) == 1.
* Only asserted for languages that have non-empty
* call_types: HCL (function_call), NICKEL (infix_expr),
* JSONNET (functioncall), STARLARK (call).
*
* FULL-PIPELINE (rh_index_files -> cbm_store_t*, via inv_count_* store helpers):
* 7. callable-sourcing : inv_count_calls_by_source(store,project,&mod,&call).
* Only asserted for languages where both func_types AND
* call_types are non-empty: NICKEL, JSONNET, STARLARK, PKL.
* 8. no-dangling : inv_count_dangling_edges(store, project, "CALLS") == 0.
* Asserted together with dim 7 when the pipeline is run.
*
* ROBUSTNESS (every language):
* R. extract-on-malformed: the extractor must RETURN (not crash/hang) on a
* deliberately truncated/broken version of the fixture. inv_extract_clean
* may return 0 (has_error is fine) but must not return NULL.
* Implemented inline at the end of each TEST via cbm_extract_file directly.
*
* STRUCTURAL-ONLY LANGUAGES (dims 1-4 + R, no calls/pipeline dims):
* JSON -- var_types = pair -> "Variable"; no func/class types.
* Dims 1-4 + R (dim 5 skipped — pair -> Variable may or may not
* extract; no class_types or func_types to assert).
* JSON5 -- same as JSON; spec has only json5_module_types + empty others.
* Dims 1-4 + R.
* YAML -- var_types = block_mapping_pair; no func/class/call types.
* Dims 1-4 + R.
* CSV -- module_types only; nothing structural extracted per-row.
* Dims 1-4 + R.
* KDL -- module_types only; no var/func/class/call types in spec.
* Dims 1-4 + R.
* RON -- module_types only; no func/class/var/call types in spec.
* Dims 1-4 + R.
* DOTENV -- module_types only; no var/func/class/call types in spec
* (key=value nodes are not mapped to any def label).
* Dims 1-4 + R.
*
* STRUCTURAL LANGUAGES WITH DEFS (dims 1-5 + R, no call dims):
* TOML -- class_types = table/table_array_element -> "Class";
* var_types = pair -> "Variable". Dims 1-5 ("Class"). No calls.
* INI -- class_types = section -> "Class"; var_types = setting.
* Dims 1-5 ("Class"). No calls.
* XML -- class_types = element -> "Class". Dims 1-5 ("Class"). No calls.
* PROPERTIES -- var_types = property -> "Variable". Dims 1-5 ("Variable"). No calls.
* PKL -- func_types = classMethod/objectMethod -> "Function";
* class_types = clazz -> "Class"; var_types = classProperty/objectProperty.
* call_types = empty_types. Dims 1-5 ("Function", "Class"). No call dim.
*
* LANGUAGES WITH CALLABLES (dims 1-6 + R, and pipeline dims 7-8 where applicable):
* HCL -- class_types = block -> "Class"; var_types = attribute;
* call_types = function_call. Dims 1-6. No func_types so no pipeline
* dim 7 (calls would be module-sourced with no Function anchor).
* NICKEL -- func_types = fun -> "Function"; call_types = infix_expr.
* Dims 1-8. Dim 7 likely RED: infix_expr nodes represent operator
* application, not named function-call sites; the enclosing-func
* walk may fail to find a parent fun node.
* JSONNET -- func_types = anonymous_function -> "Function";
* call_types = functioncall. Dims 1-8. Dim 7 likely RED:
* anonymous functions have no simple name; the enclosing-func walk
* may attribute calls at Module level.
* STARLARK -- func_types = function_definition/lambda -> "Function";
* call_types = call. Dims 1-8. Dim 7 expected GREEN for def-level
* calls; may be RED if branch walk mis-attributes nested calls.
*
* Coding rule: inline comments are line comments only (no block comments inside
* block comments).

* its body, a class/struct where the language has one, and an idiomatic
* import/include). The shared single-file + pipeline runners keep this DRY.
*
* Languages covered (12) and the CBM_LANG_* enum each uses:
* C -> CBM_LANG_C
* C++ -> CBM_LANG_CPP
* CUDA -> CBM_LANG_CUDA
* Rust -> CBM_LANG_RUST
* Go -> CBM_LANG_GO
* Java -> CBM_LANG_JAVA

*
* BATTERY DIMENSIONS
* ------------------
* SINGLE-FILE (cbm_extract_file, via inv_rx + inv_count_* helpers):
* 1. extract-clean : inv_extract_clean(src,lang,file) == 1
* (parser returned a result and did not set has_error;
* a hard crash would not return at all).
* 2. labels-valid : inv_count_bad_labels(r) == 0 (every def label is in
* the known label set).
* 3. fqn-wellformed : inv_count_bad_fqns(r) == 0 (no empty/".."/leading
* or trailing '.'/whitespace QNs).
* 4. ranges-valid : inv_count_bad_ranges(r) == 0 (start_line >= 1 and
* start_line <= end_line for every def).
* 5. defs-present : the function/class written in the fixture is extracted
* (inv_count_label for the expected def labels > 0).
* 6. calls-extracted : inv_has_call(r, "<callee>") == 1 (the in-body call was
* captured).
*
* FULL-PIPELINE (rh_index_files -> cbm_store_t*, via inv_count_* store helpers):
* 7. callable-sourcing : inv_count_calls_by_source(store,project,&mod,&call);
* assert mod == 0 -- every in-body call must be sourced
* at a Function/Method node, NEVER at a Module node.
* 8. no-dangling : inv_count_dangling_edges(store,project,"CALLS") == 0
* (every CALLS edge resolves both endpoints).
*
* KNOWN GAP (the point of this file): dimension 7 (callable-sourcing) is RED for
* most of the compiled/OOP languages on current code. Per QUALITY_ANALYSIS.md
* (2026-06-24) only ~3.69% of CALLS edges in the real graph are callable-sourced;
* the dominant failure is cbm_enclosing_func_qn falling back to the module QN when
* cbm_find_enclosing_func cannot walk the TSNode ancestry to a function node
* (func_kinds_for_lang in helpers.c not matching the grammar's emitted node
* types), and the LSP rescue cannot compensate because it joins on exact caller_qn
* equality. So dimensions 1-6 and 8 are expected GREEN for these idiomatic
* fixtures; dimension 7 is expected RED for C/C++/Rust/Java/C#/Kotlin/Scala/
* Swift/Obj-C/D and GREEN for Go/CUDA (Go is grep-validated correct; CUDA is a
* listed GREEN in the breadth table). RED dimension-7 rows ARE the deliverable.
*
* Coding rule: inline comments are line comments only (no block comments inside
* block comments).

* repro_grammar_misc.c -- FINAL per-grammar INVARIANT battery covering the
* remaining MISCELLANEOUS language family (hardware-description, CFML dialects,
* niche scripting, structural assembly/linker/tablegen/ledger/IaC). This file
* completes the all-159-grammar reproduce-first coverage: every CBM_LANG_* now
* has a per-language RED/GREEN row on the bug-repro board.
*
* One TEST() per language so per-language RED/GREEN shows on the board. Each
* test runs the battery dimension appropriate to what the language's lang_spec
* actually models (verified against internal/cbm/lang_specs.c and the
* *_func_types / *_class_types / *_call_types arrays):
*
* CALLABLE family (func_types AND call_types both non-empty) -> FULL battery
* (dims 1-8) + robustness:
* VERILOG -> CBM_LANG_VERILOG (func: function_declaration/task;
* call: system_tf_call/subroutine_call)
* SYSTEMVERILOG -> CBM_LANG_SYSTEMVERILOG (func: function_declaration/task;
* call: function_subroutine_call)
* VHDL -> CBM_LANG_VHDL (func: subprogram_declaration/def;
* call: function_call/procedure_call)
* CFML -> CBM_LANG_CFML (func: function_declaration;
* call: call_expression)
* CFSCRIPT -> CBM_LANG_CFSCRIPT (func: function_declaration; call:
* js_call_types = call_expression)
* RESCRIPT -> CBM_LANG_RESCRIPT (func: function; call: call_expression)
* SQUIRREL -> CBM_LANG_SQUIRREL (func: function_declaration; call:
* call_expression)
* PINE -> CBM_LANG_PINE (func: function_declaration_statement;
* call: call)
* TEMPL -> CBM_LANG_TEMPL (func: function_declaration/method;
* call: call_expression)
* SQL -> CBM_LANG_SQL (func: create_function; call:
* function_call/invocation/command)
*
* STRUCTURAL family (asm / linker / data / IaC) -> extract-clean +
* labels/fqn/ranges valid + defs-present (the entities each should extract) +
* robustness; NO call / pipeline dims:
* ASSEMBLY -> CBM_LANG_ASSEMBLY (func_types = {"label"}; defs are
* labels routed through the func-def
* path -> "Function"). defs-present
* asserts "Function".
* LINKERSCRIPT -> CBM_LANG_LINKERSCRIPT (only module_types + call_types; no
* func/class/var defs in spec). NO
* defs-present assertion -- dims 1-4
* + robustness only.
* TABLEGEN -> CBM_LANG_TABLEGEN (func: def/multiclass/defm ->
* "Function"; class: class -> "Class").
* defs-present asserts "Function" and
* "Class". No call_types -> no call dim.
* BEANCOUNT -> CBM_LANG_BEANCOUNT (only module_types + import_types; no
* func/class/var/call defs in spec).
* NO defs-present -- dims 1-4 +
* robustness only.
* BICEP -> CBM_LANG_BICEP (func: user_defined_function ->
* "Function"; class: resource/type/
* module_declaration -> "Class").
* defs-present asserts "Class" for the
* resource declaration. Treated as
* structural per the family split (no
* call/pipeline dim asserted).
*
* BATTERY DIMENSIONS
* ------------------
* SINGLE-FILE (cbm_extract_file, via inv_rx + inv_count_* helpers):
* 1. extract-clean : inv_extract_clean(src,lang,file) == 1
* (parser returned a result and did not set has_error; a
* hard crash would not return at all).
* 2. labels-valid : inv_count_bad_labels(r) == 0
* (every extracted def label is in the known label set).
* 3. fqn-wellformed : inv_count_bad_fqns(r) == 0
* (no empty / ".." / leading or trailing '.' / whitespace QNs).
* 4. ranges-valid : inv_count_bad_ranges(r) == 0
* (start_line >= 1 and start_line <= end_line for every def).
* 5. defs-present : at least one def with each expected label is extracted.
* 6. calls-extracted : inv_has_call(r, callee) == 1 (the in-body call was
* captured). CALLABLE family only.
*
* FULL-PIPELINE (rh_index_files -> cbm_store_t*, via inv_count_* store helpers):
* 7. callable-sourcing : inv_count_calls_by_source(store,project,&mod,&call);
* assert mod == 0 AND call >= 1 -- every in-body call must
* be sourced at a Function/Method node, NEVER at a Module
* node. CALLABLE family only.
* 8. no-dangling : inv_count_dangling_edges(store,project,"CALLS") == 0
* (every CALLS edge resolves both endpoints). CALLABLE
* family only.
*
* ROBUSTNESS (every language):
* R. extract-on-malformed: the extractor must RETURN (not crash/hang) on a
* deliberately truncated/broken version of the fixture. cbm_extract_file may
* set has_error but must not return NULL.
*
* HONEST RED CONTRACT (the point of this file): dimension 7 (callable-sourcing) is
* expected RED for the non-LSP callable languages here. None of VERILOG /
* SYSTEMVERILOG / VHDL / CFML / CFSCRIPT / RESCRIPT / SQUIRREL / PINE / TEMPL / SQL
* has a dedicated cross-LSP rescue, so attribution depends solely on the
* tree-sitter enclosing-func walk (cbm_find_enclosing_func + func_kinds_for_lang in
* helpers.c). When that mapping does not match the grammar's emitted func node
* types, the in-body call falls back to the Module QN -- exactly the enclosing-func
* drift documented for the compiled/OOP family in repro_grammar_core.c. Some of
* these languages may additionally fail dim 6 (calls-extracted) if the grammar's
* call node carries the callee on a child shape the call-extractor does not read,
* or even dim 7 vacuously (0 CALLS edges). RED rows here ARE the deliverable: they
* document the per-language attribution / extraction gaps precisely.
*
* Coding rule: inline comments are line comments only (no block comments inside
* block comments).

* SINGLE-FILE (cbm_extract_file, via inv_rx + inv_count_* helpers):

* 2. labels-valid : inv_count_bad_labels(r) == 0
* 3. fqn-wellformed : inv_count_bad_fqns(r) == 0
* 4. ranges-valid : inv_count_bad_ranges(r) == 0
* 5. defs-present : the function/method written in the fixture is extracted
* 6. calls-extracted : inv_has_call(r, "<callee>") == 1 (the in-body call)
*
* FULL-PIPELINE (rh_index_files -> cbm_store_t*, via inv_count_* store helpers):
* 7. callable-sourcing : module_sourced == 0 -- every in-body call sourced at a
* Function/Method node, NEVER at a Module node.
* 8. no-dangling : inv_count_dangling_edges(store,project,"CALLS") == 0
*
* ROBUSTNESS: each TEST also feeds a deliberately malformed fixture through the
* single-file extractor and asserts it RETURNS (no crash, NULL-or-result both
* acceptable). A hard crash would not return at all and would fail the test.
*
* KNOWN GAP (the point of this file): these are mostly grammar-only (non-LSP)
* languages, so dimension 7 (callable-sourcing) is expected RED for the majority
* via the same cbm_enclosing_func_qn -> Module fallback documented in
* repro_grammar_core.c (func_kinds_for_lang in helpers.c not matching the
* grammar's emitted function node types, with no cross-LSP rescue for these
* langs). Several langs are additionally expected RED at dimension 6
* (calls-extracted) because their call node type is unusual and the in-body
* call may not be captured at all: Wolfram (call=apply), FORM
* (call=call_statement), Agda (call=module_application), MATLAB (command/
* function_call ambiguity). RED rows ARE the deliverable -- they document the
* gap honestly per language.
*
* Coding rule: inline comments are line comments only (no block comments inside
* block comments).

/*
* repro_grammar_scripting.c -- Exhaustive per-grammar INVARIANT battery for the
* SCRIPTING / DYNAMIC language family.
*
* Mirror of repro_grammar_core.c (same helpers, same per-language battery, same
* DRY single-file + pipeline runners). One TEST() per language so per-language
* RED/GREEN shows on the bug-repro board. Each test runs the SAME battery
* against a tiny idiomatic fixture for that language (a function/method that
* CALLS another function strictly inside its body, a class where the language
* has one idiomatically, and an idiomatic import where the language has one).
*
* Languages covered (12) and the CBM_LANG_* enum each uses:
* Python -> CBM_LANG_PYTHON
* Ruby -> CBM_LANG_RUBY
* PHP -> CBM_LANG_PHP
* JavaScript -> CBM_LANG_JAVASCRIPT
* TypeScript -> CBM_LANG_TYPESCRIPT
* TSX -> CBM_LANG_TSX
* Lua -> CBM_LANG_LUA
* Perl -> CBM_LANG_PERL
* R -> CBM_LANG_R
* Julia -> CBM_LANG_JULIA
* Groovy -> CBM_LANG_GROOVY
* Dart -> CBM_LANG_DART
*
* BATTERY DIMENSIONS
* ------------------
* SINGLE-FILE (cbm_extract_file, via inv_rx + inv_count_* helpers):
* 1. extract-clean : inv_extract_clean(src,lang,file) == 1
* (parser returned a result and did not set has_error;
* a hard crash would not return at all).
* 2. labels-valid : inv_count_bad_labels(r) == 0 (every def label is in
* the known label set).
* 3. fqn-wellformed : inv_count_bad_fqns(r) == 0 (no empty/".."/leading
* or trailing '.'/whitespace QNs).
* 4. ranges-valid : inv_count_bad_ranges(r) == 0 (start_line >= 1 and
* start_line <= end_line for every def).
* 5. defs-present : the function/class written in the fixture is extracted
* (inv_count_label for the expected def labels > 0).
* 6. calls-extracted : inv_has_call(r, "<callee>") == 1 (the in-body call was
* captured).
*
* FULL-PIPELINE (rh_index_files -> cbm_store_t*, via inv_count_* store helpers):
* 7. callable-sourcing : inv_count_calls_by_source(store,project,&mod,&call);
* assert mod == 0 -- every in-body call must be sourced
* at a Function/Method node, NEVER at a Module node.
* 8. no-dangling : inv_count_dangling_edges(store,project,"CALLS") == 0
* (every CALLS edge resolves both endpoints).
*
* EXPECTED RED/GREEN (dimension 7, callable-sourcing), per QUALITY_ANALYSIS.md
* (2026-06-24), repro_invariant_calls.c, repro_invariant_breadth.c, and
* repro_invariant_enclosing_parity.c:
* GREEN (callable-sourced; regression guards):
* Python -- func_kinds_python = {function_definition}; grep-validated
* correct in QUALITY_ANALYSIS.
* JavaScript -- func_kinds_js = {function_declaration, method_definition,
* arrow_function, ...}; the simplest free-function case is
* expected callable-sourced.
* TypeScript -- shares func_kinds_js; simplest free-function case expected
* GREEN (the real-graph ts_lsp gap is for more complex bodies).
* TSX -- shares the TS/JS func_kinds; same expectation as TypeScript.
* Lua -- in the enclosing-func switch (repro_invariant_enclosing_
* parity.c); enclosing detection supported.
* Ruby -- in the enclosing-func switch; method bodies source callably.
* PHP -- in the enclosing-func switch; PHP LSP is hybrid; method/
* function bodies source callably.
* RED (module-sourced or no CALLS at all -- reproduces the gap):
* Perl -- NOT in the enclosing-func switch; its enclosing-func drift
* symptom is the documented Perl gap (repro_invariant_graph.c
* INVARIANT 4). The in-body call is sourced at Module.
* R -- "R enclosing-function detection likely missing from
* func_kinds_for_lang; call sourced at Module" (breadth file).
* Julia -- "Julia enclosing-function detection may not map
* function_definition to a callable QN; call sourced at
* Module" (breadth file).
* Groovy -- function_call callee not on a function/name field; no groovy
* branch in extract_calls.c -- likely no in-body CALLS edge,
* so dimension 7 cannot reach >=1 callable-sourced (RED).
* Dart -- selector call node carries no callee field; no dart branch
* in extract_calls.c -- likely no in-body CALLS edge (RED).
*
* Dimensions 1-6 and 8 are expected GREEN for these idiomatic fixtures across
* all 12 languages; dimension 7 is the deliverable RED signal for Perl/R/Julia/
* Groovy/Dart and the GREEN regression guard for Python/JS/TS/TSX/Lua/Ruby/PHP.
*
* Coding rule: inline comments are line comments only (no block comments inside
* block comments).

* KNOWN GAP (the point of this file): dimensions 6 and 7 are RED for most of the
* systems languages on current code. The root cause for dim 7 is the same as the
* compiled/OOP family: cbm_find_enclosing_func (helpers.c) walks the TSNode
* ancestry looking for a node whose type is in func_kinds_for_lang(lang). Only
* ZIG has a dedicated func_kinds entry among these 12; every other systems lang
* falls through to func_kinds_generic = {"function_declaration",
* "function_definition","method_declaration","method_definition"}. So the
* enclosing-func walk only succeeds (dim 7 GREEN) when the grammar's emitted
* function node type happens to be one of those generic names:
* - Zig -> function_declaration (in func_kinds_zig) -> dim 7 GREEN
* - Hare -> function_declaration (matches generic) -> dim 7 GREEN
* - Solidity -> function_definition (matches generic) -> dim 7 GREEN
* and falls back to the Module QN (dim 7 RED) for the rest, whose function node
* types are unknown to the generic set:
* - Crystal (method_def), Odin (procedure_declaration), Pony (method),
* Ada (subprogram_body), Fortran (function/subroutine),
* COBOL (program_definition), Pascal (defProc), Move (function_item).
* Nim has NO lang_spec / grammar entry at all, so it extracts zero defs and zero
* calls today: dims 5/6/7 are RED for Nim and the fixture documents that gap.
*
* When a language extracts NO in-body call today, dimension 6 (calls-extracted)
* is asserted anyway -- the language SHOULD capture the call -- so the RED row
* documents the gap precisely rather than vacuously passing. Dimensions 1-4 and
* 8 are expected GREEN throughout. RED dimension-6/7 rows ARE the deliverable.
*
* Coding rule: inline comments are line comments only (no block comments inside
* block comments).

* repro_grammar_web.c -- Per-grammar INVARIANT battery for the
* WEB / MARKUP / SCHEMA language family.
*
* One TEST() per language so per-language RED/GREEN shows on the bug-repro
* board. Each test runs a battery adapted to what the language actually models:
* many web/markup/schema languages have NO functions or calls (HTML, CSS, Vue,
* Svelte, Astro, GraphQL, Prisma, JSDoc, GoTemplate as a pure-template host).
* The battery dimensions applied per language are documented in the per-TEST
* comment.
*
* Languages covered (12) and the CBM_LANG_* enum each uses (all verified in
* internal/cbm/cbm.h; none missing, none skipped):
* HTML -> CBM_LANG_HTML
* CSS -> CBM_LANG_CSS
* SCSS -> CBM_LANG_SCSS
* Vue -> CBM_LANG_VUE
* Svelte -> CBM_LANG_SVELTE
* Astro -> CBM_LANG_ASTRO
* GraphQL -> CBM_LANG_GRAPHQL
* Protobuf -> CBM_LANG_PROTOBUF
* Thrift -> CBM_LANG_THRIFT
* Prisma -> CBM_LANG_PRISMA
* GoTemplate -> CBM_LANG_GOTEMPLATE
* JSDoc -> CBM_LANG_JSDOC
*
* BATTERY DIMENSIONS
* ------------------
* SINGLE-FILE (cbm_extract_file, via inv_rx + inv_count_* helpers):
* 1. extract-clean : inv_extract_clean(src,lang,file) == 1
* (parser returned a result and did not set has_error).
* 2. labels-valid : inv_count_bad_labels(r) == 0
* (every extracted def label is in the known label set).
* 3. fqn-wellformed : inv_count_bad_fqns(r) == 0
* (no empty/".."/leading or trailing '/'/whitespace QNs).
* 4. ranges-valid : inv_count_bad_ranges(r) == 0
* (start_line >= 1 and start_line <= end_line).
* 5. defs-present : at least one def with the expected label is extracted.
* SKIPPED for languages whose spec has no func_types,
* class_types, or field_types (HTML, CSS, Vue, Svelte,
* Astro, GoTemplate, JSDoc). A SKIP is annotated in the
* per-TEST comment; the dimension is not asserted.
* 6. calls-extracted : inv_has_call(r, callee) == 1.
* Only asserted for languages that have non-empty
* call_types: CSS (call_expression), SCSS (call_expression,
* include_statement), GoTemplate (function_call /
* template_action). Skipped for all others.
*
* FULL-PIPELINE (rh_index_files -> cbm_store_t*, via inv_count_* store helpers):
* 7. callable-sourcing : inv_count_calls_by_source(store,project,&mod,&call).
* Only asserted when dim 6 is asserted (SCSS, GoTemplate).
* For SCSS: expected RED (mixin_statement is parsed as
* func_types so a "Function" def is extracted, but
* cbm_find_enclosing_func relies on the same node being
* recognised in func_kinds_for_lang; if that mapping is
* absent the call will be sourced at Module).
* For GoTemplate: expected RED (no func_types so no
* Function/Method node exists to source the call).
* 8. no-dangling : inv_count_dangling_edges(store, project, "CALLS") == 0.
* Asserted together with dim 7 when the pipeline is run.
*
* STRUCTURAL-ONLY LANGUAGES (dims 1-5, no call/pipeline dims):

* repro_harness.h — Shared helpers for cross-file / store-level / crash bug
* reproductions (TIER A multi-file, TIER B crashes).
*
* Ported faithfully from the proven static harness in tests/test_lang_contract.c
* so cross-file repro files don't each re-derive it. Header-only (static inline)
* — each TU gets its own copy; no link conflicts. Include AFTER test_framework.h.
*
* Single-file extraction bugs do NOT need this — use cbm_extract_file directly
* (see repro_extraction.c). Use this when the bug only appears once a fixture is
* indexed through the full production pipeline (CALLS/IMPORTS/HTTP_CALLS edges,
* cross-file/cross-package resolution, Route minting, dedup/upsert, etc.).

/*
* repro_invariant_breadth.c -- Cross-language CALLS callable-sourcing invariant.
*
* INVARIANT (gap #6, QUALITY_ANALYSIS.md):
* For every language, a function call written INSIDE a function body must
* produce a CALLS edge whose source node carries label "Function" or "Method"
* (i.e. callable-sourced). It must NOT be sourced at a "Module" node.
* Calls at the top level of a file may legitimately be Module-sourced; only
* in-body calls are asserted here.
*
* QUALITY_ANALYSIS.md gap #6 reports 27 languages failing this. This file
* is the "large breadth table" — one per-language case, table-driven, asserting
* the invariant across 26 languages.
*
* Fixture design rule:
* Each fixture defines exactly TWO functions: a callee (helper) and a caller
* (run) that calls helper strictly INSIDE its body. There are NO top-level
* calls in any fixture. This means ANY Module-sourced CALLS edge is a
* direct violation of the invariant.
*
* Expected RED/GREEN split (as of QUALITY_ANALYSIS.md, 2026-06-24):
* GREEN (already correctly callable-sourced, regression guards):
* elixir, ocaml, fortran, pascal, cuda, d, glsl, hlsl, ispc,
* odin, slang, squirrel, vimscript, cairo (14 cases)
*
* RED (module-sourced or no CALLS at all -- reproduces the gap):
* r, julia, dart, groovy, commonlisp, powershell, ada, clojure,
* fsharp, racket, rescript, scheme (12 cases)
*
* Note: the "suspicious" group (r, julia, ...) from QUALITY_ANALYSIS may be
* GREEN because the calls-breadth table (test_lang_contract.c) already shows
* expect_calls=true for most. The module-sourcing assertion is STRICTER: a
* language can produce a CALLS edge (calls >= 1) but still fail here if the
* edge is sourced at Module rather than Function. Individual case comments
* explain the known failure mode where root-caused.
*
* How to read results:
* PASS -- callable-sourced (Function/Method), no Module-sourced in-body calls.
* If currently GREEN: regression guard -- a future grammar/pipeline
* change that breaks sourcing will turn it RED.
* If currently RED: the bug is confirmed reproduced; fix the
* enclosing-function detection for this language.

* type matches the list, cbm_find_enclosing_func returns a null node and
* cbm_enclosing_func_qn falls back to the module QN. The LSP rescue path
* (pass_lsp_cross.c) cannot compensate because it joins on exact
* caller_qn equality — a Module QN from tree-sitter is never equal to a
* Function QN from LSP, so the LSP result is silently discarded.
*
* EXPECTED per language (based on helpers.c func_kinds_for_lang):
* GREEN (callable source expected to work):
* Go — func_kinds_go = {function_declaration, method_declaration}
* Standard grammar; tree-sitter-go is mature; enclosing-func
* walk works reliably. Python/Go confirmed correct in
* QUALITY_ANALYSIS grep validation.
* Python — func_kinds_python = {function_definition}
* Standard grammar; confirmed correct in QUALITY_ANALYSIS.
*
* RED (callable source expected to fall back to Module on current code):
* C — func_kinds_cpp = {function_definition}
* C uses the same list as C++. QUALITY_ANALYSIS top-file
* list is dominated by C files (extract_defs.c: 182 Module-
* sourced CALLS, c_lsp.c: 86). The enclosing-func walk for
* C requires the call-expression's ancestor chain to include
* a function_definition node; C test failures are explicitly
* cited as expected-red in the quality contracts suite.
* C++ — same func_kinds as C. Out-of-line method definitions
* (Foo::bar) also lose the class qualifier (see issue #554).
* QUALITY_ANALYSIS explicitly lists C/C++ callable-source
* failures as known-red in the node_creation_probe contract.
* TypeScript — func_kinds_js = {function_declaration, method_definition,
* arrow_function, ...}. Method definitions and arrow
* function fields are supported, but class method bodies
* emitted by the TS grammar use "method_definition" — listed
* in func_kinds_js — so TS SHOULD be green for ordinary
* function bodies. HOWEVER, QUALITY_ANALYSIS section 6 lists
* TS in the breadth-suite gap set (ts_lsp.c: 95 Module-
* sourced CALLS in the real graph). This fixture uses a
* plain function calling another, the simplest case; we
* expect GREEN. If TS still fails the test will document it.
* Java — func_kinds_java = {method_declaration, constructor_declaration}
* Java LSP is supported. The real-graph audit shows
* java_lsp.h: 90 Module-sourced CALLS. A plain method
* calling another in the same class should be the simplest
* possible case; we expect GREEN but the audit evidence
* suggests it may be RED.
* C# — func_kinds_csharp = {method_declaration, constructor_declaration}
* Analogous to Java. Similar LSP support. Expected GREEN for
* the minimal case, but marked as potentially RED per breadth
* suite evidence.
* Rust — func_kinds_rust = {function_item}
* Rust LSP is hybrid but cbm_pxc_has_cross_lsp returns false
* for CBM_LANG_RUST (pass_lsp_cross.c:281). The enclosing-
* func walk uses only tree-sitter. Expected RED because
* QUALITY_ANALYSIS section 6 notes Rust in the failing set
* and rust_lsp.h: 102 Module-sourced CALLS appears in the
* top-file list.
*
* ASSERTION (per edge):
* For every cbm_edge_t e where e.type == "CALLS":
* cbm_store_find_node_by_id(store, e.source_id, &src) == CBM_STORE_OK
* AND (strcmp(src.label, "Function") == 0 || strcmp(src.label, "Method") == 0)
* Equivalently: module_sourced_count == 0.
*
* NOTE: inline comments below use line comments only (no block comments

* DISTINCT module QNs → GREEN (guard)
* 5. pkg_a/mod.py + pkg_b/mod.py → different path prefixes → GREEN (guard)
*
* Assertion for RED cases: after indexing, cbm_store_find_nodes_by_name()
* for the shared symbol name returns only 1 node (collapse detected).
* The ASSERT_GTE(distinct, 2) then fires RED, proving the bug.
*
* Assertion for GREEN cases: after indexing, the store holds >= 2 distinct
* nodes for each shared symbol name (both definitions survive).

/*
* repro_invariant_enclosing_parity.c — Enclosing-function detection DRIFT
* (QUALITY_ANALYSIS gap #3).
*
* INVARIANT (same family as repro_invariant_calls.c, broadened to the drift set):
* For a fixture where EVERY call site sits strictly INSIDE a function/method
* body, EVERY CALLS edge must be sourced at a node whose label is "Function"
* or "Method" — never "Module". A Module-sourced CALLS edge proves the
* enclosing-function walk failed.
*
* ROOT CAUSE (verified against the tree, 2026-06-26):
* helpers.c cbm_find_enclosing_func() (helpers.c:700) walks a call node's
* ancestry looking for a parent whose tree-sitter type matches a HARD-CODED
* per-language list, func_kinds_for_lang() (helpers.c:644). Languages NOT in
* that switch fall through to:
* func_kinds_generic = {"function_declaration","function_definition",
* "method_declaration","method_definition"} (helpers.c:641)
* But lang_specs.c defines `*_func_types[]` (the grammar function node types)
* for 100+ languages. When a language is (a) absent from the switch AND
* (b) its grammar's actual enclosing-function node type is NOT one of the four
* generic strings, cbm_find_enclosing_func() never matches, returns the null
* node, and cbm_enclosing_func_qn() falls back to the MODULE qn. Every call
* inside such a function is then attributed to Module. The LSP rescue path
* (pass_lsp_cross.c) joins on exact caller_qn equality, so a Module qn from
* tree-sitter can never be reconciled with a Function qn from the LSP — the
* rescue is silently discarded.
*
* THE SWITCH (helpers.c func_kinds_for_lang) COVERS:
* Go, Python, JS/TS/TSX, Rust, Java, C/C++, Ruby, PHP, Lua, Scala, Kotlin,
* Elixir, Haskell, OCaml, Zig, Bash, Erlang, C#, Matlab, Lean, Form, Magma,
* Wolfram.
* (Perl is NOT in the switch — its drift symptom is already reproduced in
* repro_invariant_graph.c INVARIANT 4; this file does NOT duplicate Perl.)
*
* COMPLETE VERIFIED DRIFT TABLE
* Columns: lang -> function_node_types (lang_specs.c) -> in switch? ->
* intersects generic? -> drift verdict.
* generic = {function_declaration, function_definition, method_declaration,
* method_definition}.
*
* FULLY-DRIFTED (in switch? NO ; generic-intersect? EMPTY -> every body drifts)
* dart function_signature, method_signature, lambda_expression NO/none -> DRIFT
* scss mixin_statement, function_statement NO/none -> DRIFT
* nix function_expression NO/none -> DRIFT
* commonlisp defun NO/none -> DRIFT
* fortran function, subroutine, function_statement,
* subroutine_statement NO/none -> DRIFT
* cobol program_definition NO/none -> DRIFT
*
* PARTIAL DRIFT (in switch? NO ; generic-intersect? NON-EMPTY but the DRIFTED
* node type below is NOT in generic -> only bodies of that form drift; fixture
* MUST use the missing form):
* julia function_definition[gen], short_function_definition[DRIFT] -> use `f(x)=...`
* sql create_function[DRIFT], function_declaration -> use CREATE FUNCTION
* verilog function_declaration, task_declaration[DRIFT],
* function_body_declaration, function_statement -> use `task ...`
* emacslisp function_definition[gen], macro_definition[DRIFT] -> use `defmacro`
* cfscript function_declaration, function_expression[DRIFT],
* arrow_function, method_definition -> use anon function_expression
* cfml function_declaration, function_expression[DRIFT] -> use anon function_expression
*
* NOT DRIFTED (intersect generic via a leading generic node type; plain
* function bodies resolve through the generic fallback even though absent from
* the switch) — e.g. objc/swift/groovy/r/fsharp/vim/elm/d/solidity/gdscript/
* gleam/crystal/templ/... all lead with function_declaration|function_definition.
*
* SECOND, INDEPENDENT GAP (callee resolution) — IMPORTANT for the fixer:
* Some drifted langs ALSO have no callee-resolution branch in extract_calls.c
* (test_lang_contract.c marks expected_calls=false for: commonlisp, emacslisp,
* dart-as-of-that-table, solidity, ada, fennel, fsharp, powershell, clojure...).
* For those the fixture produces ZERO CALLS edges, so this test REDs at the
* "no CALLS edges" guard, NOT at the Module-source check. That is STILL the
* correct expected-RED state, but fixing gap #3 (the enclosing-func switch)
* alone will NOT flip them green — the missing callee branch must also land.
* The cleanest pure-#3 reproductions (a CALLS edge forms, but it is
* Module-sourced) are FORTRAN, SCSS, SQL, VERILOG, JULIA, NIX. Each per-lang
* comment states which failure class applies.
*
* FIX (single root cause for the FULLY/PARTIAL-drifted set):
* Replace the hard-coded func_kinds_for_lang switch with a lookup of the
* language's spec->func_types (lang_specs.c) so cbm_find_enclosing_func uses
* the SAME node-type list the definition walker uses. Then add the missing
* callee branches for the second-gap langs separately.
*
* ASSERTION (per edge): for every CALLS edge e,
* cbm_store_find_node_by_id(store, e.source_id, &src) == CBM_STORE_OK AND
* (src.label == "Function" || src.label == "Method"); i.e. module_sourced == 0.
* PLUS: at least one CALLS edge must exist (zero edges is a no-signal fixture).
*
* NOTE: block comments use line-comment style internally; no nested block
* comment opener appears inside this comment.

* repro_invariant_lsp_rescue.c — QUALITY_ANALYSIS gap #5 / #5a:
* the LSP rescue cannot recover a bad tree-sitter caller QN because the
* join key is exact caller-QN string equality.
*
* THE BLOCKER (file:func:line):
* cbm_pipeline_find_lsp_resolution (src/pipeline/lsp_resolve.h:48)
* joins each LSP-resolved call (CBMResolvedCall) to the tree-sitter call
* (CBMCall) with EXACT string equality on the caller QN:
*
* lsp_resolve.h:65:
* if (strcmp(rc->caller_qn, call->enclosing_func_qn) != 0)
* continue;
*
* Consumed by:
* - src/pipeline/pass_calls.c:369 (sequential pipeline,
* resolve_single_call → emit_classified_edge)
* - src/pipeline/pass_parallel.c:1797 (parallel pipeline)
*
* When tree-sitter's enclosing-func walk FAILS, cbm_enclosing_func_qn
* falls back to the MODULE QN, so call->enclosing_func_qn is the module
* QN. The C/C++ LSP cross resolver (internal/cbm/lsp/c_lsp.c) builds its
* OWN enclosing QN from scope resolution — for an out-of-line method
* Foo::bar it produces the real method QN "<proj>.<module>.Foo.bar"
* (c_process_function, c_lsp.c:4138-4143) and emits a CBMResolvedCall
* with caller_qn = that real method QN, strategy = "lsp_direct" /
* "lsp_implicit_this" / "lsp_type_dispatch", confidence 0.95
* (c_emit_resolved_call, c_lsp.c:3287-3296). 0.95 is well above
* CBM_LSP_CONFIDENCE_FLOOR (0.6f, lsp_resolve.h:36).
*
* So the LSP HAS the correct caller, but the join key on the
* tree-sitter side is the MODULE QN. module-QN != real-method-QN, the
* strcmp at lsp_resolve.h:65 never matches, find_lsp_resolution returns
* NULL, the LSP rescue branch (pass_calls.c:370-385) is skipped, and the
* edge falls through to the registry resolver — staying Module-sourced
* with a registry strategy. The LSP rescue is silently DISCARDED.
*
* FIXTURE RATIONALE (C++ out-of-line method — the #554 family):
* A free function helper() and a class Processor with an OUT-OF-LINE
* method definition Processor::run that calls helper(v). For the
* out-of-line method body, tree-sitter's cbm_find_enclosing_func cannot
* walk the call-expression's ancestry back to a node whose type is in
* func_kinds_cpp = {"function_definition"} in a way that yields the
* class-qualified method QN, so cbm_enclosing_func_qn falls back to the
* module QN (issue #554 / extract_defs.c + c_lsp.c dominate the
* QUALITY_ANALYSIS Module-sourced-CALLS top-file list). C/C++ has a
* cross-file LSP wired up (cbm_pxc_has_cross_lsp, pass_lsp_cross.c:281),
* so the LSP DOES resolve the real Processor::run caller. This is the
* cleanest fixture where tree-sitter attribution lands on Module but the
* LSP resolves the real enclosing function — exactly gap #5a.
*
* EXPECTED vs ACTUAL:
* EXPECTED (correct, what the fix must produce): the helper() CALLS edge
* is sourced at the real callable node Processor::run (label
* "Function"/"Method"), via the LSP rescue, and its properties_json
* carries the LSP strategy marker (strategy starts with "lsp_") and the
* LSP confidence (0.95).
* ACTUAL (today, RED): the join discards the LSP result, so the edge is
* Module-sourced and its properties carry a registry strategy
* (same_module / import_map / ...), never an "lsp_" strategy.
*
* This file deliberately complements repro_invariant_calls.c: that file
* asserts the broad "zero Module-sourced CALLS" invariant; THIS file
* pins the *mechanism* — that the LSP rescue specifically is the missing
* recovery, by also asserting the rescued edge preserves the LSP
* strategy/confidence in its properties_json (gap #5a, second assertion).
*
* NOTE: line comments only inside this header (no block comments inside a

* repro_issue221.c -- Regression guard for bug #221.
*
* Bug #221: "'install' command does not work for opencode in windows 11"
*
* ROOT CAUSE:
* find_in_path (src/cli/cli.c) probed only the bare executable name
* "opencode" for each PATH entry. On Windows, CLI tools installed via
* mise/npm/scoop ship as extension-bearing shims (.cmd, .ps1, .exe), so
* the bare-name probe never matched and cbm_find_cli("opencode", ...) always
* returned an empty string. The installer therefore concluded opencode was
* absent and skipped wiring it even when it was present on PATH.
*
* FIX (commit 0485d3f, "fix(cli): probe Windows PATHEXT variants in
* find_in_path (#221)"):
* On _WIN32, find_in_path now iterates the common PATHEXT variants
* (.exe, .cmd, .bat, .ps1) for each PATH directory after the bare-name
* probe fails, matching whichever extension-qualified file is present.
*
* REGRESSION GUARD -- expected GREEN on current main (fix is in):
* The fix was committed as 0485d3f and CI (build-windows + test-windows)
* was green before merge. This test is therefore expected to PASS on the
* current codebase. It will turn RED if find_in_path is accidentally
* regressed to bare-name-only lookup.
*
* CROSS-PLATFORM STRATEGY:
* On POSIX: create a plain executable named "opencode" (no extension).
* Bare-name lookup has always worked here, so the test confirms
* cbm_find_cli("opencode", ...) resolves correctly -- the baseline.
* On Windows: create "opencode.cmd" (the most common shim format).
* Before the fix, find_in_path returned "" for this case; after
* the fix it returns the .cmd path -- the regression guard proper.
* Both branches exercise the same public function and assertion; only the
* fixture filename differs.
*
* NOTE: no slash-star inside this block comment to avoid nested-comment UB.

/*
* repro_issue333.c — Reproduce-first case for OPEN bug #333.
*
* Bug #333: "Silent index degradation — status:'indexed' but only ~500 nodes
* for 72k LOC Rust" (reclassified as Rust extraction-depth gap).
*
* ROOT CAUSE — push_nested_class_nodes silently drops trait method defs:
* When the definition walker encounters a Rust `trait_item` node it is
* classified as a class (label "Interface") and `push_class_body_children`
* is called to schedule its children for further traversal.
* `push_class_body_children` finds the `declaration_list` body node (the
* Rust grammar's name for a trait body) and delegates to
* `push_nested_class_nodes` (extract_defs.c ~line 4890).
* `push_nested_class_nodes` only re-queues children that are in
* `spec->class_node_types` (struct_item, enum_item, etc.) or are named
* "field_declaration" / "template_declaration" / "declaration".
* It does NOT re-queue `function_item` or `function_signature_item` nodes.
* Therefore every method defined inside a trait body — both abstract
* declarations (function_signature_item, e.g. `fn area(&self) -> f64;`)
* and default implementations (function_item, e.g. `fn describe(&self) {}`)
* — is silently dropped and never reaches `extract_func_def`.
*
* EXPECTED (correct) behaviour:
* Extracting a Rust source file that defines a trait with methods must
* produce:
* - The trait itself as label "Interface" (already works).
* - Every method declared in the trait body as label "Method" (broken).
* Specifically for the fixture below:
* - Trait "Shape" → Interface node (already present)
* - Abstract method "area" inside trait Shape → Method node (MISSING)
* - Abstract method "perimeter" inside trait Shape → Method node (MISSING)

* `r->defs` contains the Interface node for Shape but zero Method nodes
* for the three methods declared in its body. The ASSERT_EQ(3, ...) below
* evaluates to ASSERT_EQ(3, 0) and FAILs → RED.
*
* NOT covered by existing tests:
* - test_extraction.c::rust_struct tests `impl` block methods via the
* separate `extract_rust_impl` path, which is NOT affected by this bug.
* - test_rust_lsp.c trait tests (rustlsp_cov_trait_simple_method, etc.)
* only check `r->resolved_calls` (the LSP layer), never `r->defs`, so
* they do not detect missing trait-method def nodes.
* - test_matrix_new_constructs.c::mn_multiple_trait_bounds_rust tests a
* function with trait BOUNDS, not a trait DEFINITION with methods.
* No existing test asserts that method definitions inside a Rust `trait`
* body appear in `r->defs` — this is the first.
*
* FIX LOCATION:
* `push_nested_class_nodes` in internal/cbm/extract_defs.c (~line 4900):

*
* Issue: #363 — "Linux: cbm_system_info / cbm_default_worker_count don't
* respect cgroup CPU/memory limits"
*
* Both axes of #363 have shipped; this case is now a permanent GREEN guard:
*
* CPU axis — FIXED in v0.8.0 (commit a5a3d1d).
* cbm_detect_cgroup_cpus() reads /sys/fs/cgroup/cpu.max (v2) or
* .../cpu/cpu.cfs_quota_us + .../cpu/cpu.cfs_period_us (v1); the result
* feeds detect_system_linux(). cbm_default_worker_count() also honours the
* CBM_WORKERS env override (commit d952238). Both tested in test_platform.c.
*
* Memory axis — FIXED.
* cbm_detect_cgroup_mem() reads /sys/fs/cgroup/memory.max (v2) or
* .../memory/memory.limit_in_bytes (v1); detect_system_linux() applies
* min(cgroup, host). The missing env knob — the "EXACT OPEN GAP" this
* repro was filed for — now exists: cbm_mem_init() reads CBM_MEM_BUDGET_MB
* and routes it through the pure cbm_mem_resolve_budget() (explicit
* override > implicit detection, mirroring CBM_WORKERS).
*
* IMPORTANT — clamp semantics:
* cbm_mem_resolve_budget() clamps the override to effective (cgroup/host) RAM
* so it can never claim more than the box has. So a *large* override is NOT
* honoured verbatim on a small host — it clamps to total_ram. This guard
* therefore uses a small budget (REPRO363_BUDGET_MB) that is at/below any
* realistic host's RAM, so it is honoured exactly and the assertion is stable
* on every runner. The clamp behaviour itself is unit-tested separately in
* tests/test_mem.c (resolve_budget_override_clamped_to_total).
*
* NOTE on cbm_mem_init() caching:
* g_budget is initialised once via atomic_compare_exchange_strong, so this
* guard relies on running before any suite that calls cbm_mem_init(); the
* repro runner does not init the budget before this suite.

/*
* repro_issue382.c — Reproduce-first case for OPEN bug #382.
*
* Bug #382: "Java: @Annotation, signatures, and all AST properties missing
* from graph nodes"
*
* Root cause (confirmed by maintainer + reporter re-open):
* extract_decorators() in internal/cbm/extract_defs.c first scans
* ts_node_prev_sibling() looking for nodes of type "annotation" /
* "marker_annotation". In the Java AST emitted by tree-sitter-java, those
* nodes are NOT prev-siblings of either the class_declaration or the
* method_declaration — they live INSIDE the node's own `modifiers` child:
*
* class_declaration
* modifiers
* marker_annotation <- @Entity
* marker_annotation <- @RestController
* type_identifier: "User"
* class_body
* method_declaration
* modifiers
* marker_annotation <- @Override
* annotation <- @GetMapping("/users")
* type_identifier: "String"
* ...
*
* The code does have a fallback that calls find_jvm_modifiers() to search
* the `modifiers` child when prev-sibling count == 0, which covers the
* simple @GetMapping-on-method case already tested in test_extraction.c
* (extract_java_method_annotations_issue382, which passes green on v0.7.0).
*
* What is NOT covered by that existing test:
* a) CLASS-LEVEL annotations (@Entity, @RestController) on the class node
* itself — the existing test only extracts Method nodes; it never
* checks the Class node's .decorators.
* b) marker_annotation (no-arg form, e.g. @Override, @Entity) on methods
* — the existing test uses @GetMapping("/x") which is a full
* `annotation` node with arguments and does a substring match against
* the whole text "@GetMapping(\"/x\")". marker_annotations have a
* different tree-sitter node type and are historically mis-counted.
* c) Multiple stacked annotations on a single method/class.
*
* These cases regress when the fallback path is absent or broken (e.g. the
* fix only wired the method path, not the class path, or it works for
* `annotation` nodes but not `marker_annotation`).
*
* Expected (correct) behaviour:
* - The Class def for "User" carries decorators:
* decorators[0] contains "Entity"
* decorators[1] contains "RestController" (or vice-versa)
* - The Method def for "getUser" carries decorators:
* at least one entry contains "Override"
* at least one entry contains "GetMapping"
* - method "getUser" has a non-empty signature.
*
* Actual (buggy) behaviour:
* - Class def for "User": decorators == NULL (no annotations extracted)
* - Method def for "getUser": marker_annotation @Override is dropped;
* decorators may be NULL or miss @Override.
* → assertions below are RED on current code if either path is broken.
*
* Why this is STRONGER than the existing test_extraction.c #382 reference:
* 1. It asserts decorators on the CLASS node — never checked before.
* 2. It specifically asserts that a marker_annotation (@Override, @Entity)
* is captured, not just a full annotation with arguments.
* 3. It asserts BOTH annotations on a multi-annotated class, exercising the
* count loop that must find > 1 entry.
* 4. It uses ASSERT_NOT_NULL(m->decorators) before touching decorators[i],
* so a NULL decorators field fails loudly rather than crashing/skipping.

* repro_issue403.c -- Reproduce-first case for OPEN bug #403.
*
* Issue: #403 -- "The IDE's installation directory is unnecessarily indexed"
* https://github.com/DeusData/codebase-memory-mcp/issues/403
*
* Wrongly-indexed directory: AppData/Local/Programs/Antigravity
* (the Antigravity IDE install tree; reported name confirmed in issue comments)
*
* Root cause (src/discover/discover.c):
* cbm_should_skip_dir() (line 339) tests only the BARE directory name
* (entry->name, the last path component) against ALWAYS_SKIP_DIRS and
* FAST_SKIP_DIRS. None of "AppData", "Local", "Programs", or "Antigravity"
* appears in either list. Therefore cbm_discover() walks straight into the
* IDE install tree and indexes every source-like file it contains.
*
* There is no install-directory guard at ANY layer:
* - ALWAYS_SKIP_DIRS covers VCS, build tools, and caches -- not IDE
* install prefixes (Programs, AppData/Local/Programs, etc.).
* - The .gitignore path is only loaded when a .git directory is present
* (is_git_repo gate, line 777 of discover.c). An IDE install dir does
* not contain .git, so .gitignore exclusions never fire.
* - The cbmignore path (opts->ignore_file or .cbmignore at root) is
* similarly absent from an install dir by default.
* Result: any source-extension file found under Antigravity/ is returned
* as a discovered file, bloating the graph with IDE internals.
*
* Expected (correct) behaviour:
* When cbm_discover() is called on a directory that contains an
* "Antigravity" subdirectory (or more generally any IDE install subtree),
* files under that subdirectory must NOT appear in the discovered file list.
* The correct fix (per the issue owner's comment) is to add "Antigravity"
* (and the broader "Programs" / install-dir pattern) to the exclusion layer,
* OR to extend the exclusion to root-path patterns so auto-index never picks
* an install dir as a project root in the first place.
*
* Actual (buggy) behaviour:
* cbm_discover() returns files under Antigravity/ as normal discovered
* files because the bare dirname "Antigravity" is absent from ALWAYS_SKIP_DIRS.
*
* Why RED on current code:
* The fixture creates a temp dir with:
* normal.py -- a legitimate source file (control: MUST appear)
* Antigravity/ide.py -- sentinel inside the IDE install dir (MUST NOT appear)
* cbm_discover() is called on the temp dir. The loop below asserts that
* ide.py is NOT in the result. On current code "Antigravity" is not skipped,
* so ide.py IS discovered and the ASSERT_FALSE fires RED.
*
* Fix location (not implemented here):
* src/discover/discover.c, ALWAYS_SKIP_DIRS array:
* Add "Antigravity" (and any other IDE install dir names to be excluded)
* to the NULL-terminated list. The broader fix is to extend the list with
* install-path components ("Programs", "AppData") or, per the issue owner,
* to implement a root-path exclusion in the auto-index root-selection logic
* so directories under AppData/Local/Programs are never chosen as repo roots.
*
* Exclusion is NOT config-driven in the current code. The closest knob is a
* .cbmignore file at the repo root (loaded unconditionally, unlike .gitignore
* which requires .git/). Passing opts->ignore_file also works. However,
* neither is set in this test -- we assert on the default behaviour, which is
* what the bug reporter experiences.

* repro_issue408.c — Reproduce-first case for OPEN bug #408.
*
* Issue #408: "package.json `workspaces` cross-repo IMPORTS still produce
* zero edges"
*
* Root cause (pass_pkgmap.c / pipeline.c):
* In a Yarn/Lerna-style JS/TS monorepo, `packages/b` imports a sibling by
* its declared package name (`import { x } from '@org/a'`). pass_pkgmap.c
* is supposed to:
* 1. Walk the repo filesystem for package.json manifests (cbm_pkgmap_scan_repo).
* 2. Parse each sibling package.json, mapping its `"name"` field to its
* entry-point QN (parse_package_json → pkg_entries_push).
* 3. On import resolution (cbm_pipeline_resolve_module), perform an exact
* lookup of `"@org/a"` in the pkgmap hash table to obtain the sibling's
* QN, then produce an IMPORTS edge to that node.
*
* The reporter's debug trace (macOS arm64, v0.7.0) shows that the pkgmap
* pass never emits any `pkgmap.*` log lines:
* pipeline.done nodes=12 edges=9 elapsed_ms=71
* — zero IMPORTS edges despite a bare-specifier workspace import. The
* maintainer confirmed: on macOS/Linux cbm_pkgmap_scan_repo may resolve
* workspace names at the manifest-parse level (cbm_pkgmap_try_parse), but
* the resolved entry-QN is never matched against the in-graph node produced
* by indexing `packages/a/index.js`. The mismatch means the exact-lookup
* in cbm_pipeline_resolve_module (step 3) silently falls through to
* default (unresolved) QN resolution, and no cross-package IMPORTS edge is
* ever produced.
*
* Expected (correct) behaviour:
* Indexing a minimal monorepo:
* root/package.json { "workspaces": ["packages/<glob>"] }
* packages/a/package.json { "name": "@org/a", "main": "index.js" }
* packages/a/index.js export function fromA() { return 1; }
* packages/b/package.json { "name": "@org/b", "main": "index.js" }
* packages/b/index.js import { fromA } from '@org/a';
* export function useA() { return fromA(); }
* must produce AT LEAST ONE IMPORTS edge in the graph.
* (The only possible target of `import … from '@org/a'` is the sibling
* package — there are no relative imports in this fixture.)
*
* Actual (buggy) behaviour:
* rh_count_edges(store, project, "IMPORTS") == 0
* The assertion ASSERT_GTE(imports, 1) FAILS → RED.
*
* Why STRONGER than the existing weak test
* (`contract_edge_workspaces_imports_issue408` in tests/test_lang_contract.c):
*
* The existing test asserts `edge_present(f, 5, "IMPORTS", 1)`, which
* succeeds whenever ANY IMPORTS edge exists in the indexed project. In the
* original test_lang_contract.c fixture this is satisfied trivially by a
* relative import or a self-import resolved within a single package — the
* cross-package bare-specifier resolution is never exercised.
*
* This repro fixture is DESIGNED so the only source of IMPORTS edges is the
* bare-specifier cross-package import in packages/b/index.js:
* import { fromA } from '@org/a';
* Neither packages/a/index.js nor packages/b/index.js contains any
* relative import ("./…") or intra-package import. Therefore:
* rh_count_edges(..., "IMPORTS") >= 1
* is ONLY satisfiable if the cross-package workspace resolution succeeded.
* On current (buggy) code this count is 0, so the assertion is RED.
*
* In addition, the fixture omits `"dependencies"` from packages/b/package.json
* on purpose: workspace resolution must be driven purely by the monorepo
* `"workspaces"` glob, not by an explicit `dependencies` field — matching
* the reporter's minimal repro from the issue comments.

* repro_issue409.c — Reproduce-first case for OPEN bug #409.
*
* Issue #409: "v0.7.0 install/update wires the legacy blocking PreToolUse
* gate, not hook_augment (regresses #214)"
*
* Root cause (as filed):
* cbm_install_hook_gate_script wrote the legacy blocking shell gate
* (keyed on $PPID, emitting `exit 2` to block tool calls) instead of the
* non-blocking augmenter shim that delegates to `<binary> hook-augment`.
* On an upgrade from a pre-v0.7.0 install the old gate script remained on
* disk (or was rewritten with blocking content), so every Grep/Glob call
* was blocked rather than being non-blocking augmented — the exact symptom
* of #214 which was supposed to be fixed.
*
* Expected (correct) behaviour after cbm_upsert_claude_hooks +
* cbm_install_hook_gate_script:
* 1. The gate script written to
* <home>/.claude/hooks/cbm-code-discovery-gate
* MUST contain "hook-augment" (delegating to the compiled augmenter).
* 2. The gate script MUST NOT contain "PPID" (the $PPID-keyed blocking
* logic) or "exit 2" (the blocking exit code).
* 3. The settings.json PreToolUse command must reference
* "cbm-code-discovery-gate" (the shim), not an inline blocking script.
*
* Actual (buggy) behaviour (if bug is present):
* The gate script still contains $PPID and exit 2; the assertions below
* that check for absence of "PPID" and "exit 2" FAIL -> RED.
*
* Upgrade scenario tested here (NOT covered by existing tests):
* This test simulates an upgrade from a pre-v0.7.0 install by:
* a) Pre-seeding the gate-script path with the OLD blocking content
* (containing $PPID and exit 2) — as would be present on disk after
* a pre-v0.7.0 install.
* b) Pre-seeding settings.json with a stale CMM hook entry using the
* old "Grep|Glob|Read" matcher and an old command string.
* Then running both cbm_upsert_claude_hooks + cbm_install_hook_gate_script
* (the actual install/update code path) and asserting the CORRECT result.
*
* This is the critical gap: existing tests call cbm_install_hook_gate_script
* into an EMPTY directory (no pre-existing script). The upgrade path
* (old script on disk) was not verified to be overwritten correctly.
*
* Relationship to existing tests:
* cli_hook_gate_script_no_predictable_tmp_issue384 (test_cli.c:2196):
* Tests cbm_install_hook_gate_script in isolation on a fresh dir.
* Does NOT test the upgrade/overwrite scenario.
* cli_upsert_claude_hook_fresh (test_cli.c:2167):
* Tests cbm_upsert_claude_hooks in isolation on fresh settings.json.
* Does NOT test the integrated (both calls) upgrade path.
*
* NOTE (2026-06-26): Code review of the current codebase shows that
* cbm_install_hook_gate_script already uses fopen(path, "w") (truncate)
* and writes the non-blocking shim. If this test is GREEN it means the bug
* is fixed on main and the issue can be closed (the test then acts as a
* permanent regression guard for this upgrade scenario).

* exactly ONE mcp.json path for VS Code:
* macOS - <home>/Library/Application Support/Code/User/mcp.json

*
* Expected (correct) behaviour:
* When Code/User/profiles/<id>/ directories exist at install time, the
* install should ALSO write an mcp.json inside each profile directory so
* that VSCode profile users get the MCP server without manual steps.
* Concretely: after cbm_build_install_plan_json() (the dry-run oracle for

/*
* repro_issue434.c - Reproduce-first case for OPEN bug #434.
*
* Issue: #434 - "cursor | vscode : persistence=true is silently ignored on
* first artifact creation"
*
* Root cause:
* In src/pipeline/pipeline_incremental.c, the static function
* dump_and_persist() (around line 668) auto-exports the artifact only when
* one ALREADY exists on disk:
*
* if (repo_path && cbm_artifact_exists(repo_path)) {
* cbm_artifact_export(db_path, repo_path, project, CBM_ARTIFACT_FAST);
* }
*
* It never consults p->persistence. So when index_repository is called with
* persistence=true for the FIRST time (no prior artifact), the incremental
* path skips the export entirely. The full-pipeline path in pipeline.c
* correctly gates on p->persistence (line 933: if (p->persistence) {...}),
* but cbm_pipeline_run_incremental() calls the local dump_and_persist()
* which only checks cbm_artifact_exists(), not the pipeline flag.
*
* The MCP handler in mcp.c (line 2794) further exposes the symptom:
* if (persistence && has_artifact) { ... artifact_hint ... }
* This condition can never be true on a first run because has_artifact is
* checked AFTER the incremental path ran and produced no artifact.
*
* Expected (correct) behaviour:
* Calling index_repository with persistence=true on a repo that has no
* prior artifact MUST create .codebase-memory/graph.db.zst after the run.
* cbm_artifact_exists(repo_path) MUST return true after the first
* persistence=true index, not only after a second run.
*
* Actual (buggy) behaviour:
* After the first persistence=true call on a fresh repo, no artifact is
* written. cbm_artifact_exists() returns false. Only a SECOND call (when
* the artifact now exists from a prior run) writes the file.
*
* Why RED on current code:
* We call index_repository once with persistence=true on a fresh fixture
* repo (no prior artifact). We then assert cbm_artifact_exists() returns
* true. On buggy code dump_and_persist() skips the export because
* cbm_artifact_exists() was false at the time of the check, so the
* assertion fires RED.
*
* Fix location (not implemented here):

* repro_issue471.c - Reproduce-first case for OPEN bug #471.
*
* Issue: #471 - "GLR ambiguity-merge is O(n^2) for deeply-nested ambiguous
* grammars (e.g. Perl), even with the recursion-depth cap"
*
* Pathological construct:
* A deeply-nested Perl function call chain of the form:
* f(f(f(f(... f(1) ...))))
* where `f` is called with paren-optional syntax, causing the Perl grammar to
* produce `ambiguous_function_call_expression` nodes at every nesting level.
* This is the exact shape named by the original reporter (halindrome) and
* confirmed in the maintainer comment on #471.
*
* Why O(n^2):
* tree-sitter's GLR merge path in `stack_node_add_link`
* (internal/cbm/vendored/ts_runtime/src/stack.c, function starting at line 200)
* is called recursively when two candidate parse-stack heads share compatible
* predecessor nodes (same TSStateId, same byte position, same error_cost).
* For an N-deep ambiguous call chain, the merge loop at the outermost level
* iterates over N-1 existing links while each inner recursive call adds another
* sweep over the growing link list. The result is O(N^2) total
* stack_node_add_link invocations.
*
* The `CBM_TS_STACK_MERGE_MAX_DEPTH` cap added in #461 bounds call-stack
* RECURSION DEPTH (preventing SIGSEGV) but does NOT cap the total number of
* iterations across all recursive calls. Hence: no crash, but superlinear
* parse time that grows without bound as N increases.
*
* Evidence from issue #471 (post-cap measurements):
* N=2000 -> completes in < 1 s (sub-quadratic or near-linear at small N)
* N=30000 -> takes > 5 minutes (clearly superlinear; effectively a hang)
* We choose N=5000 as the reproduction depth:
* - O(N^2) at N=5000 is ~6x more work than at N=2000, which already
* finishes in <1 s, putting the blowup firmly inside the alarm window.
* - A correct O(N) or O(N log N) implementation finishes at N=5000
* in well under 1 s, so the 15-second bound is a very generous pass
* threshold for a fixed implementation.
*
* Expected (correct) behaviour after fix:
* Parsing the N=5000 deeply-nested Perl file completes within 15 seconds,
* i.e. the forked child exits normally (WIFEXITED, not WIFSIGNALED).
*
* Actual (buggy) behaviour on current code:
* The GLR merge work grows superlinearly; the child exceeds the 15-second
* wall-clock budget and is killed by SIGALRM. The parent's waitpid() sees
* WIFSIGNALED(status) && WTERMSIG(status) == SIGALRM, so
* ASSERT_FALSE(WIFSIGNALED(status)) fires RED.
*
* Timing-based flakiness note:
* Any timing reproduction carries inherent flakiness on loaded machines.
* Mitigations applied:
* 1. The alarm bound (15 s) is ~15x the expected buggy blowup threshold
* and far above the expected pass time (<1 s) for a fixed impl.
* 2. N=5000 was chosen to sit in the steeply-growing O(n^2) regime
* (not the knee) so the gap between pass and fail is large.
* 3. The fork/alarm pattern isolates wall-clock from test-runner load.
* On a very heavily loaded machine a false PASS is more likely than a
* false FAIL (the OS may slow a fixed impl to near the bound), but a
* false FAIL for a correct O(n) impl at this bound is implausible.
*
* Fix location (not implemented here):
* internal/cbm/vendored/ts_runtime/src/stack.c, `stack_node_add_link`:
* bound the total merge work (an overall ambiguity-merge iteration budget
* or memoization of already-merged node pairs) consistent with the existing
* MAX_LINK_COUNT bail-out at line 249, so parse time stays near-linear for
* adversarially ambiguous input.

* under heavy CI load, so the assertion "the deeply-nested ambiguous parse
* TERMINATES within ALARM_SECONDS (no hang/crash from the #461-capped GLR
* recursion)" is now deterministic on every platform. The O(n^2) PERFORMANCE bug

* repro_issue480.c — Reproduce-first case for OPEN bug #480.
*
* Issue: #480 — "trace_path returns empty for all functions despite
* traversable CALLS edges (v0.8.1, macOS arm64)"
*
* Root cause (identified by maintainer DeusData + reporter halindrome):
* handle_trace_call_path() calls cbm_store_find_nodes_by_name() to locate
* the start node for BFS. On the affected build, the name-to-node lookup
* returns node_count == 0 for EVERY function name — even names that the
* graph clearly contains (confirmed by query_graph Cypher returning the same
* function with 5–8 inbound CALLS edges). The fallback to
* cbm_store_find_node_by_qn() also returns nothing, so the handler exits
* with a "function not found" error OR (when the node IS found by name)
* the BFS start-node id does not match any edge endpoint stored in the
* graph, so cbm_store_bfs() returns visited_count == 0 and the "callers"
* / "callees" JSON arrays are serialised empty.
*
* The split: query_graph Cypher (direct SQL) traverses the same edges
* correctly, while trace_path (BFS via start-node id) yields nothing.
* This isolates the bug to trace_path's own start-node lookup or to how
* the resolved node id is passed to cbm_store_bfs(), NOT to edge creation.
*
* Expected (correct) behaviour:
* After indexing a two-function Python file where caller() calls callee(),
* trace_path for "callee" with direction="inbound" must return a non-empty
* "callers" array that contains a node named "caller".
*
* Actual (buggy) behaviour:
* trace_path returns {"function":"callee","direction":"inbound","callers":[]}
* — an empty "callers" array — even though CALLS edges exist in the graph
* and are walkable via query_graph.
*
* Why RED on current code:
* The precondition assertion (CALLS edges > 0) passes because edge creation
* is correct. The subsequent assertion that resp contains the string
* "\"caller\"" (the caller function's name embedded in the callers array)
* FAILS because cbm_store_bfs() finds no hops from the resolved start node.
*
* How this isolates the traversal bug from an extraction bug:
* If CALLS edges were the problem, rh_count_edges(store, …, "CALLS") would
* return 0 and the ASSERT_GT precondition would fire RED — visibly flagging
* an extraction failure instead. By asserting the precondition GREEN and
* the trace_path result RED, we prove the edges exist and the fault lies
* exclusively in trace_path's traversal layer.
*
* Fix location (not implemented here):
* cbm_store_find_nodes_by_name() or cbm_store_bfs() in
* src/store/store.c — the node id returned by name lookup must match
* the source/target ids stored in the edges table.

* repro_issue495.c — Reproduce-first case for issue #495:
* "cfg-gated twin functions collapse into one node; get_code_snippet
* returns the inactive branch's body"
*
* ROOT CAUSE (extraction layer):
* extract_func_def() computes:
* def.qualified_name = cbm_fqn_compute(project, rel_path, name)
* for every Rust function_item it visits. Two same-named functions
* guarded by mutually-exclusive #[cfg(...)] attributes both parse as
* distinct function_item nodes and both pass through extract_func_def,
* but they receive the SAME qualified_name (no cfg predicate is folded
* in). When the graph store upserts them it hits the UNIQUE(project,
* qualified_name) constraint and the second write silently overwrites
* the first — one branch is lost entirely.
*
* EXPECTED (correct) behavior:
* Each cfg-gated twin must receive a DISTINCT qualified_name that
* encodes its cfg predicate, e.g.
* "t.src.try_extract_pdf_text" (active / feature branch)
* "t.src.try_extract_pdf_text#cfg(not(feature=\"rag-pdf\"))" (stub)
* So that the graph can keep BOTH nodes and get_code_snippet can return
* the correct body for the requested cfg context.
*
* ACTUAL (buggy) behavior:
* Both defs carry identical qualified_name "t.src.try_extract_pdf_text".
* The assertion `qn_a != qn_b` FAILS (both equal the same string), so
* this test is RED on unpatched code.
*
* SECONDARY assertions (also RED until fixed, targeting the same root
* cause from different angles):
* • The REAL-body function has param name "bytes" (no underscore);
* the STUB has "_bytes". Each def's signature must correspond to its
* own branch — i.e. BOTH signatures must appear in the result, one
* containing "bytes" without a leading underscore and one with "_bytes".
* • Each def's decorators[0] must contain the cfg predicate of ITS OWN
* branch (not the other's), so that a fixer can easily scope-qualify
* the QN from the already-captured decorator text.
*
* Why these assertions are RED on current code:
* All three assertions require distinguishing the two defs by their QN.
* Since both QNs are currently identical, any loop looking for "the
* active branch" finds the SAME node twice, and the body-token /
* decorator checks collapse to checking ONE def against itself.

* repro_issue510.c — Reproduce-first case for OPEN bug #510.
*
* Issue: #510 — ".gitignore (non repo root) gaps and overrides"
*
* Root cause (discovered via discover.c):
* cbm_discover_ex() loads the root .gitignore ONLY when a .git directory is
* present at repo_path (is_git_repo gate, ~line 777). For a non-git-root
* call (e.g. indexing pkg/ directly), is_git_repo = false and gitignore =
* NULL. The nested-gitignore fallback also fails: try_load_nested_gitignore()
* has the guard "if (frame->local_gi || frame->prefix[0] == '\0') return NULL"
* (line 630). The initial walk frame always has prefix == "" (empty), so
* prefix[0] == '\0' is true and the function returns NULL without even
* stat-ing the .gitignore file. Result: the .gitignore sitting at the root
* of the indexed directory is completely silently ignored, so every file
* that it excludes gets indexed anyway.
*
* Expected (correct) behaviour:
* When cbm_discover() is called on a directory that is NOT a git repo root
* but DOES contain a .gitignore, that .gitignore MUST be honoured.
* A file matching a pattern in that .gitignore must NOT appear in the
* discovered file list.
*
* Actual (buggy) behaviour:
* cbm_discover() returns the excluded file as a normal discovered file
* because try_load_nested_gitignore() refuses to load .gitignore when
* the walk frame prefix is empty (i.e. the indexed directory itself).
*
* Why RED on current code:
* The fixture creates a directory WITHOUT a .git sub-directory (so the
* is_git_repo gate stays false), writes a .gitignore containing "secret.py",
* and writes secret.py + keep.py. After cbm_discover(), the loop below
* checks that secret.py is NOT in the result. On the current code the
* check FAILS because secret.py is present in the discovered list.
*
* Fix location (not implemented here):
* src/discover/discover.c, function try_load_nested_gitignore():
* Remove (or invert) the "frame->prefix[0] == '\0'" early-return guard so
* that the function also loads .gitignore from the root indexed directory.
* Additionally, cbm_discover_ex() should attempt to load a root .gitignore
* even when the directory is not a git repo.

/*
* repro_issue514.c -- Reproduce-first case for OPEN bug #514.
*
* Issue: #514 -- "trace_path data_flow mode doesn't surface arg expressions;
* NestJS DI patterns defeat ~70% of caller resolution"
*
* Sub-claim reproduced: (A) data_flow mode omits argument expressions.
*
* Why sub-claim A over sub-claim B (NestJS DI caller resolution):
* (A) has a crisp binary assertion: the "e" field either appears in the JSON
* output or it does not. (B) is a statistical claim (~70% failure rate) that
* requires a NestJS-specific fixture and a headcount of resolved callers across
* many call sites -- impossible to assert precisely in a unit test. (A) can
* be reproduced with a small two-function Python fixture and one strstr check.
*
* Root cause:
* The MCP schema for trace_path documents data_flow mode as "follow CALLS +
* DATA_FLOWS with arg expressions" (mcp.c line 356-357 and 363-364). Argument
* expressions at each call site ARE stored in the graph: pass_parallel.c::
* append_args_json serializes each CBMCallArg as {"i":<index>,"e":"<expr>,...}
* into the CALLS edge properties_json column. However,
* bfs_to_json_array() (mcp.c ~line 2283) only emits the node fields (name,
* qualified_name, hop, risk, is_test) from cbm_node_hop_t. The edge that
* carried the arg expressions is NOT propagated by cbm_store_bfs() into the
* cbm_traverse_result_t (cbm_edge_info_t carries only from_name, to_name,
* type, confidence -- no properties_json). So even if the user requests
* mode="data_flow", every hop in the response lacks the "args" field and the
* individual arg expression text ("e") is permanently absent from the output.
*
* Expected (correct) behaviour:
* After indexing a two-function Python file where caller() passes a compound
* expression (payload_info + 1) to callee(), a trace_path call with
* mode="data_flow" and direction="outbound" on "caller" must include the
* argument expression text "payload_info" in the response JSON -- either in an
* "args" array inside the hop object, or as a standalone "e" field.
*
* Actual (buggy) behaviour:
* The response is:
* {"function":"caller","direction":"outbound","mode":"data_flow",
* "callees":[{"name":"callee","qualified_name":"...","hop":1}]}
* The hop object contains NO "args" and NO "e"/"arg_expr" field.
* strstr(resp, "payload_info") returns NULL.
*
* Why RED on current code:
* The precondition assertion (CALLS edges >= 1) passes -- edge creation
* and arg serialisation in pass_parallel.c are correct. The final
* ASSERT_NOT_NULL(strstr(resp, "payload_info")) FAILS because
* bfs_to_json_array() never reads or re-emits edge properties_json, so the
* arg expression "payload_info" stored in the CALLS edge is permanently
* discarded before it reaches the MCP JSON output.
*
* Fix location (not implemented here):
* cbm_store_bfs() in src/store/store.c must propagate edge properties_json
* into the cbm_traverse_result_t (extend cbm_edge_info_t or cbm_node_hop_t).
* bfs_to_json_array() in src/mcp/mcp.c must then emit an "args" field when

* repro_issue521.c — Reproduce-first case for issue #521.
*
* BUG: "Route nodes created from URL strings in config / non-source files"
*
* Root cause (pipeline.c:try_upsert_infra_route + helpers.c:is_url_like):
*
* 1. extract_unified.c:handle_string_refs() walks every string node in a
* YAML file. Any value containing "://" passes cbm_classify_string()
* as CBM_STRREF_URL, landing in CBMFileResult.string_refs.
*
* 2. pipeline.c:cbm_pipeline_extract_infra_routes() iterates files that
* match is_infra_file() — which includes ".yaml" / ".yml" — and calls
* try_upsert_infra_route() for every CBM_STRREF_URL entry whose value
* contains "://".
*
* 3. try_upsert_infra_route() unconditionally mints a "Route" node:
* cbm_gbuf_upsert_node(gbuf, "Route", sr->value, route_qn, ...)
* with no check for whether the URL is an upstream-config value (e.g.
* an auth-server JWKS URL, a Terraform registry URL, a healthcheck
* target) versus an actual route this service exposes.
*
* Correct behaviour: a YAML/config file that only contains upstream URL
* strings (no route-registration syntax, no handler definitions) MUST NOT
* yield any Route node in the graph.
*
* Why RED on current code: try_upsert_infra_route has no guard that
* prevents minting Route nodes from arbitrary CBM_STRREF_URL values in
* config files. Indexing the fixture below produces ≥ 2 Route nodes
* (one per upstream URL string), so ASSERT_EQ(route_count, 0) FAILS.

/*
* repro_issue523.c — Reproduce-first case for issue #523.
*
* BUG: "cross-repo-intelligence returns 0 edges for a byte-identical call/route"
*
* Root cause (pass_calls.c::resolve_single_call):
*
* When a Python client uses `import requests` and calls
* `requests.get("/api/orders/{id}")`, the `requests` package is an external
* pip dependency whose source is NOT present in the indexed tree.
* `cbm_registry_resolve` resolves the callee name to a candidate QN
* containing "requests", but `cbm_gbuf_find_by_qn(ctx->gbuf, res.qualified_name)`
* returns NULL — the node does not exist in the graph because `requests` was
* never indexed. The guard at pass_calls.c::resolve_single_call line ~406:
*
* const cbm_gbuf_node_t *target_node = cbm_gbuf_find_by_qn(ctx->gbuf, res.qualified_name);
* if (!target_node || source_node->id == target_node->id)
* return 0; ← call is SILENTLY DROPPED
*
* causes the call to be silently dropped before it ever reaches
* `emit_classified_edge` / `emit_http_async_edge`. No HTTP_CALLS edge is
* created in the client project DB.
*
* Without an HTTP_CALLS edge in the client DB, `match_http_routes` in
* pass_cross_repo.c finds nothing to iterate over, and `cbm_cross_repo_match`
* returns http_edges == 0 — even when the server project has a perfectly
* matching Route node (byte-identical path, correct method) and a HANDLES
* edge pointing to the handler function.
*
* Expected (correct) behaviour:
* A call to an external HTTP client library (e.g. `requests.get`) with a
* URL/path first argument MUST produce an HTTP_CALLS edge in the client
* project DB, even when the library's source is not indexed. The linker
* should detect the service-pattern match on the resolved QN substring
* ("requests") and emit the edge before consulting the node graph.
* Subsequently, `cbm_cross_repo_match` must produce at least one
* CROSS_HTTP_CALLS edge linking the client caller to the server route handler
* when the client url_path (canonicalized) matches the server Route QN.
*
* Actual (buggy) behaviour:
* cbm_cross_repo_match returns http_edges == 0. The assertion below is RED.
*
* Companion: pass_calls.c (sequential path) and pass_parallel.c (parallel path)
* both share the same guard; fixing one requires fixing both.
*
* Note on parallel pipeline:
* HTTP_CALLS edges are produced on BOTH the sequential (< 50 files) and
* parallel (>= 50 files) pipeline paths, so this test uses a small fixture
* (< 50 files) and exercises the sequential path. The parallel path has the
* same root cause and is covered by the same fix (pass_parallel.c::
* finalize_and_emit has an identical unindexed-node guard).

/*
* repro_issue546.c — Reproduce-first case for OPEN bug #546.
*
* Issue: #546 — "trace_path / reverse-dependency returns an INCOMPLETE caller
* set when a symbol is duplicated by an ambient .d.ts declaration
* (callers silently split by import style)"
*
* Root cause (graph layer — node identity / dedup across the ambient declaration):
* When a TypeScript symbol is BOTH defined in a real .ts source file AND
* re-declared (body-less, signature only) in an ambient .d.ts shim file,
* the indexer creates TWO distinct Function nodes for the same logical symbol
* (one rooted at the .ts implementation, one rooted at the .d.ts stub).
*
* CALLS edges from consumers are then partitioned across the two nodes based
* on which import form each consumer used:
* - consumer importing via relative path ("./scroll") → CALLS edge targets
* the IMPLEMENTATION node (packages/widget/src/scroll.ts)
* - consumer importing via path alias ("@widget") → CALLS edge targets
* the .d.ts STUB node (app/types/widget-shim.d.ts)
*
* trace_path resolves the symbol name to EXACTLY ONE of the two nodes (the
* first one returned by cbm_store_find_nodes_by_name) and BFS-traverses only
* that node's inbound CALLS edges. The callers whose edges point to the OTHER
* node are silently omitted from the result. There is no warning that the
* symbol resolved to multiple nodes and the caller set is therefore partial.
*
* Expected (correct) behaviour:
* trace_path(function_name="alignToEdge", direction="inbound") must return
* ALL callers, regardless of which import style they used:
* {"callers": [{name: "internalConsumer", ...}, {name: "externalConsumer", ...}]}
* Both "internalConsumer" AND "externalConsumer" must appear in the response.
*
* Actual (buggy) behaviour:
* Only ONE of the two callers appears in the "callers" array. The other is
* silently dropped because its CALLS edge points to the sibling node (the
* other representation of the same logical symbol) that trace_path did not
* select as its BFS root.
*
* Why RED on current code:
* The final assertion checks that BOTH caller names appear in the trace_path
* JSON response. On buggy code, trace_path picks one of the two Function
* nodes for "alignToEdge" as its BFS root; the inbound CALLS edges of the
* OTHER node are never visited; one caller name is absent from the JSON;
* the strstr check for the missing name returns NULL →
* ASSERT_NOT_NULL(strstr(resp, "...")) FAILS → RED.
*
* Precondition strategy:
* Before driving trace_path, the test checks that BOTH callers produced
* at least one CALLS edge each (total CALLS edges ≥ 2). If this precondition
* fires RED it flags an extraction failure (TS CALLS extraction not working),
* not the #546 traversal bug. Separation keeps the root cause unambiguous.
*
* TS CALLS extraction reliability note:
* TypeScript CALLS extraction is confirmed reliable for simple intra-package
* call expressions by existing integration tests (test_extraction.c and the
* regression suite). The known risk here is the path-alias import form
* ("@widget") — the extractor may or may not resolve the alias and produce
* a CALLS edge for externalConsumer. If the precondition (total CALLS ≥ 2)
* fires first, the alias resolution is the cause, not the #546 split.
* A secondary precondition after the main assertion ensures that even if only
* one CALLS edge is produced (alias unresolved), the test is still RED for
* the right reason: incomplete caller set.
*
* Fix location (not implemented here):
* Either in cbm_store_find_nodes_by_name / cbm_store_bfs (union traversal
* across all nodes sharing name+signature), or in the pipeline dedup step
* where body-less .d.ts stub nodes should be merged/aliased into their
* implementation counterpart rather than stored as separate graph nodes.

/*
* repro_issue548.c — Reproduce-first case for OPEN bug #548:
* "D:\\ drive and custom path cannot be selected in server UI"
*
* Issue #548 — reporter: navigating to a non-C: drive path (e.g. D:\projects\x)
* or any custom path via the server UI file-picker results in the path being
* rejected by the backend. The user cannot index a repository on D:\ (or any
* drive other than C:\) through the browser UI.
*
* ROOT CAUSE — handle_browse() in src/ui/http_server.c, specifically two
* co-located defects in the GET /api/browse handler:
*
* DEFECT A (line ~411) — missing cbm_normalize_path_sep() before cbm_is_dir():
* The raw "path" query parameter (which may carry Windows backslash
* separators, e.g. "D:\projects\demo") is passed directly to cbm_is_dir()
* without first normalizing backslashes to forward slashes via
* cbm_normalize_path_sep(). On POSIX cbm_is_dir() never matches a path
* containing literal backslashes (the backslash is a valid filename
* character on POSIX, so "D:\projects\demo" is a single path component
* that does not exist). Result: a real directory on a Windows D: drive
* always triggers the "not a directory" 400 error — the UI can never open
* it. cbm_normalize_path_sep() is already called on the repo_path in the
* MCP handler (mcp.c:2806) and in cbm_project_name_from_path() (fqn.c:332),
* but the browse handler was skipped.
*
* DEFECT B (line ~461) — drive-root parent truncated to bare "X:":
* After a successful directory listing, handle_browse() computes the
* "parent" directory with:
*
* char *last_slash = strrchr(parent, '/');
* if (last_slash && last_slash != parent)
* last_slash = '\0';
* else
* snprintf(parent, sizeof(parent), "/");
*
* For a normalized Windows drive-root path "D:/" the last '/' is at
* index 2 ("D:/", positions 0='D', 1=':', 2='/'). Since index 2 != 0
* (not the same as 'parent' pointer), the branch takes the truncation
* path and sets parent = "D:" (strips the '/'). The resulting "parent"
* field in the JSON response is "D:" — a bare drive spec without a
* trailing separator. When the UI navigates to that parent, the next
* browse request calls cbm_is_dir("D:") which on Windows resolves to the
* current directory on drive D (not the drive root), and on POSIX fails
* entirely. The user is stuck: they can enter the drive but cannot
* navigate back to its root, blocking path selection.
*
* Correct behavior: the parent of "D:/" must be "D:/" itself (the drive
* root is its own parent, the same convention POSIX uses for "/").
*
* EXPECTED (correct) behavior:
* A valid Windows path such as "D:/projects/demo" (or the backslash form
* "D:\projects\demo") submitted as a browse query must be:
* 1. Normalized to forward slashes before reaching cbm_is_dir().
* 2. Responded to with a 200 JSON listing (not a 400 error) when the
* directory exists.
* Additionally, when browsing a drive root "D:/", the returned "parent"
* field must be "D:/" (self-referential root, matching POSIX "/" convention),
* NOT the truncated bare-drive form "D:".
*
* ACTUAL (buggy) behavior:
* DEFECT A: browse with a backslash path (path=D:\projects\demo) returns 400
* because cbm_is_dir() sees the un-normalized backslash string.
* DEFECT B: browse for "D:/" returns parent="D:" instead of "D:/", stranding
* the user at the drive root because the next cbm_is_dir("D:") fails or
* resolves to the wrong directory.
*
* WHY RED on current code:
* test_repro_issue548_cbm_is_dir_rejects_backslash_path:
* Creates a real tmpdir on disk. Converts the forward-slash path to a
* backslash form (simulating what the Windows UI sends). Asserts that
* cbm_is_dir() returns true for the backslash form — exactly what
* handle_browse() would require after the missing normalize call.
* On POSIX, cbm_is_dir() always returns false for a backslash path
* (the OS treats backslash as a valid filename character, not a separator,
* so the path does not exist). ASSERT fails → RED.
* This directly documents the missing cbm_normalize_path_sep() call in
* handle_browse(): the normalize function IS correct (see TEST C), but
* handle_browse() never calls it before cbm_is_dir().
*
* test_repro_issue548_drive_root_parent_correct:
* Reproduces the parent-path computation from handle_browse() using the
* exact same strrchr logic. Feeds "D:/" and asserts that the computed
* parent equals "D:/" (drive root is its own parent). On current code the
* strrchr branch strips the trailing '/' and produces "D:" →
* strcmp(parent, "D:/") != 0 → ASSERT_STR_EQ FAILS → RED.
* This test is 100% cross-platform (pure string logic, no I/O, no D: drive
* required) and will be RED on all platforms including macOS CI.
*
* FIX LOCATION (not implemented here — reproduce only):
* DEFECT A: add cbm_normalize_path_sep(path) after cbm_http_query_param()
* in handle_browse() (src/ui/http_server.c, around line 409).
* DEFECT B: in the parent-path computation block, check whether the stripped
* result ends with ':' (bare Windows drive spec) and restore the trailing
* '/' when it does; or, more generally, treat "X:/" as a drive root whose
* parent is itself (analogous to POSIX "/" whose parent is itself).
*
* COVERAGE CAVEAT:
* Neither test exercises the full handle_browse() HTTP handler end-to-end
* (handle_browse is a static function; calling it requires a live HTTP
* server and a real socket connection). TEST A is a direct call to
* cbm_is_dir() on the un-normalized path — it proves the gate that
* handle_browse() uses would reject the backslash form, but does not drive
* the HTTP layer. TEST B is pure string logic verbatim-copied from the
* handler. Both tests are sufficient to pin the root causes and will turn
* GREEN when the two-line fix is applied to handle_browse().

*
* WHY RED on current code (DEFECT A):
* handle_browse() (src/ui/http_server.c:411) calls cbm_is_dir(path) before
* calling cbm_normalize_path_sep(path). When the query param carries
* Windows backslashes (e.g. "D:\projects\demo"), the raw backslash string
* reaches cbm_is_dir() un-normalized.
*
* On POSIX (macOS/Linux CI), cbm_is_dir() wraps stat(2). The OS treats
* backslash as a valid filename character — not a path separator — so the
* path "tmp\cbm_repro548_abc123" (with backslashes) is a single component
* that does not exist in the filesystem. stat() returns ENOENT →
* cbm_is_dir returns false. The handler then returns 400 "not a directory".
*
* This test creates a real tmpdir so that cbm_is_dir() WOULD return true if
* the path were normalized (forward slashes). It then converts the path to
* backslash form (mimicking the Windows browser UI) and asserts that

/*
* repro_issue557.c -- Reproduce-first case for OPEN bug #557.
*
* Issue: #557 -- "cbm v0.8.1 silently deletes project DBs on 'corrupt'
* detection -- data loss with no recovery"
*
* DESTROYING CODE PATH:
* src/mcp/mcp.c resolve_store() lines 796-810
*
* The sequence is:
* 1. resolve_store() opens the project DB with cbm_store_open_path_query().
* 2. It calls cbm_store_check_integrity() (src/store/store.c:664).
* That function returns false when the projects table contains a row
* whose root_path does not start with '/', 'A'-'Z', or 'a'-'z' (the
* numeric-string corruption pattern -- e.g. "826" -- observed in the
* binary and confirmed in the issue report).
* 3. On false, resolve_store() calls cbm_unlink(path) at mcp.c:803,
* then cbm_unlink(wal_path) and cbm_unlink(shm_path) -- with NO rename,
* NO backup, NO recovery path. The user's indexed project is gone.
*
* ROOT CAUSE:
* "Delete on first suspicion" design in resolve_store(). The unlink is
* unconditional and irreversible. Any false-positive integrity signal
* (WAL/SHM leftover after SIGKILL, schema-version drift between standard
* and UI binary variants, or a root_path value that happens not to match
* the narrow whitelist) causes permanent data loss.
*
* EXPECTED (correct) behaviour:
* After cbm_store_check_integrity() returns false and resolve_store()
* executes its cleanup path, EITHER:
* (a) the original DB file must still exist at db_path (zero deletion), OR
* (b) a backup file must exist at a nearby path (e.g. "<db_path>.corrupt"
* or "<db_path>.bak") so the user can recover the data.
* The original DB must NOT be silently destroyed with no recovery path.
*
* ACTUAL (buggy) behaviour on v0.8.1:
* cbm_unlink(path) at mcp.c:803 destroys the DB file. After resolve_store()
* returns, access(db_path, F_OK) returns -1 (ENOENT) and no backup file
* exists -- total data loss.
*
* WHY RED on current code:
* The final ASSERT_TRUE checks that EITHER db_still_exists OR backup_exists.
* On buggy code cbm_unlink() runs with no rename, so both conditions are
* false and ASSERT_TRUE fires -- RED.
*
* TRIGGER:
* We construct the scenario directly at the store API level (no full index
* needed -- the integrity check runs before any graph data is consulted):
*
* 1. Set CBM_CACHE_DIR to a temp directory so the DB lands in a controlled
* location and does not pollute the real cache.
* 2. Create the DB via cbm_store_open_path() (creates schema + tables).
* 3. Insert one projects row with root_path = "826" -- the exact numeric
* string from the binary evidence in the issue report. This passes the
* "> 5 rows" check (only 1 row) but trips the bad_root_path check in
* cbm_store_check_integrity() because '8' is not '/', 'A'-'Z', or 'a'-'z'.
* 4. Close the store, verify the DB file exists (precondition).
* 5. Call cbm_mcp_handle_tool(srv, "search_graph", ...) with the project
* name. search_graph resolves the project store via resolve_store(),
* which opens the DB, runs the integrity check, detects bad_root_path,
* and executes the destroying cbm_unlink() at mcp.c:803.
* 6. Assert survival: DB file still exists OR a backup exists.
*
* NOTE on determinism:
* The "826" root_path value is a deterministically planted value -- not
* dependent on kill timing or WAL state. cbm_store_check_integrity() is
* a pure SQL query; its result for root_path="826" is guaranteed to be
* false on any build. The trigger is 100% reproducible.
*
* FIX LOCATION (not implemented here):
* src/mcp/mcp.c resolve_store() around line 803:
* Replace cbm_unlink(path) with a rename to a timestamped .corrupt path,
* then log a prominent error so the user knows where the preserved file is.

/*
* repro_issue56.c — Reproduce-first case for OPEN bug #56.
*
* Bug #56: "Cross-crate call graphs stop at boundaries" (Rust)
*
* ROOT CAUSE (pipeline / Rust LSP path):
* The tree-sitter-only Rust extractor has no access to Cargo metadata
* at extraction time, so when it sees `crate_a::helper()` inside
* crate_b, it records a raw call-site for the path but has no registry
* entry for `crate_a::helper` — only the definitions in the *same file*
* were seeded. The LSP resolver therefore cannot match the call-site to
* a callee QN across the crate boundary, and the resulting
* CBMResolvedCall is either absent or marked with low confidence and
* discarded. When the pipeline writes graph edges for this project, no
* CALLS edge is minted for the cross-crate call — the call graph stops
* at the crate edge.
*
* v0.8.1 added a hybrid-LSP Rust path that "materially improves" this
* (issue comment, maintainer 2026-06-25), but the reporter was asked to
* retest; the issue remains OPEN because no retest confirming resolution
* was provided. The workspace-member wiring test
* (rustlsp_extra_cargo_wires_workspace_member in test_rust_lsp.c) only
* exercises the *single-file LSP* layer with a manually-parsed manifest;
* it does NOT verify that the full production pipeline (rh_index_files →
* cbm_pipeline → graph store) persists a cross-crate CALLS edge for a
* real multi-file Cargo workspace fixture. That gap is what this test
* fills.
*
* FIXTURE:
* A minimal Cargo workspace with two crates:
*
* [workspace Cargo.toml] — workspace root, declares members
* crate_a/Cargo.toml — library crate "crate_a"
* crate_a/src/lib.rs — exposes `pub fn helper() {}`
* crate_b/Cargo.toml — binary crate "crate_b", depends on crate_a
* crate_b/src/main.rs — calls `crate_a::helper()` from `fn run()`;
* also defines a LOCAL `fn helper()` to break
* bare-name uniqueness (see note below)
*
* The only meaningful cross-crate CALLS edge is:
* crate_b::run → crate_a::helper
*
* EXPECTED (correct) behaviour:
* After indexing the workspace through the production MCP pipeline, the
* graph store must contain at least one CALLS edge whose TARGET node's
* qualified_name contains "crate_a" (i.e. routes into the crate_a
* namespace, not into crate_b's local helper).
*
* ACTUAL (buggy) behaviour:
* The pipeline extracts both files, but the cross-crate path
* `crate_a::helper` in crate_b/src/main.rs is not resolved to a graph
* node in crate_a because Cargo workspace member metadata is not
* plumbed into the per-file extraction phase. Result: zero CALLS edges
* to the crate_a namespace.
*
* WHY THIS IS RED ON CURRENT CODE (even post-v0.8.1):
* The rustlsp_extra_cargo_wires_workspace_member unit test exercises only
* the LSP layer (cbm_run_rust_lsp_with_manifest called with a parsed
* CBMCargoManifest) and confirms the resolver *can* route
* `engine::boot()` to `engine.boot` when given the manifest explicitly.
* BUT: the production pipeline's per-file extraction path
* (cbm_extract_file → cbm_run_rust_lsp) does NOT receive a pre-parsed
* workspace manifest — it only gets the individual file's content.
* Additionally, cbm_pxc_has_cross_lsp() returns false for CBM_LANG_RUST
* (pass_lsp_cross.c), so the cross-file LSP pass is never invoked for
* Rust. Therefore a real workspace indexed through index_repository
* produces no CALLS edges crossing into crate_a, and this test is RED.
*
* WHY THE OLD >= 2 COUNT TEST FALSE-PASSED:
* With a unique `helper` name in the project (one definition in crate_a,
* no other `helper` anywhere), the generic pipeline name resolver
* (registry.c, resolve_name_lookup) resolves `crate_a::helper` to the
* sole `helper` candidate by bare-name suffix scoring — WITHOUT needing
* any cross-crate workspace metadata. This produced calls >= 2 (the
* intra-file main→run plus the bare-name-resolved run→helper), making
* the old ASSERT_GTE(calls, 2) GREEN even though the bug was not fixed.
*
* Fix: add a LOCAL `fn helper()` in crate_b/src/main.rs so there are
* now TWO `helper` candidates in the project registry. The generic
* resolver either picks the wrong one (crate_b-local) or abstains
* (ambiguous). Only a correctly crate-qualified resolver routes
* `crate_a::helper` specifically to crate_a's node. The assertion then
* checks the TARGET node's qualified_name contains "crate_a" — a count
* check is no longer sufficient because the local helper also contributes
* a CALLS edge (run_local→helper).
*
* UNCERTAINTY:
* If a future version plumbs workspace metadata or wires Rust lsp_cross
* correctly, this test will go GREEN — that is the intended outcome.

/*
* repro_issue570.c -- Reproduce-first case for OPEN bug #570.
*
* BUG #570: "Installer adds hooks to both hooks.json and config.toml"
* https://github.com/DeusData/codebase-memory-mcp/issues/570
*
* TWO FILES WRONGLY WRITTEN (Codex SessionStart hook):
* ~/.codex/config.toml -- always written by cbm_upsert_codex_hooks()
* ~/.codex/hooks.json -- pre-existing JSON hook representation
*
* ROOT CAUSE (src/cli/cli.c, install_cli_agent_configs, ~line 3116-3130):
* The Codex install path unconditionally passes config.toml as the hook
* target to cbm_upsert_codex_hooks():
*
* snprintf(cp, sizeof(cp), "%s/.codex/config.toml", home);
* ...
* cbm_upsert_codex_hooks(cp);
*
* It never checks whether ~/.codex/hooks.json already exists. When a user
* has configured Codex via hooks.json (the JSON representation), the
* installer still writes the SessionStart hook into config.toml, causing
* Codex to warn about loading hooks from both representations simultaneously.
*
* The same blind write is reflected in the install plan path (~line 3123):
*
* if (g_install_plan)
* plan_record("Codex CLI", "hook", cp); -- cp is always config.toml
*
* So cbm_build_install_plan_json() always lists config.toml as the Codex
* hook target, even when hooks.json is already in use.
*
* EXPECTED vs ACTUAL (oracle: cbm_build_install_plan_json plan JSON):
* Scenario: ~/.codex/ exists AND ~/.codex/hooks.json exists.
*
* Expected: hooks_planned for Codex CLI lists ~/.codex/hooks.json as the
* hook target (the representation already in use). config.toml
* may still appear as an mcp_config target, but NOT as a hook.
* Actual: hooks_planned lists ~/.codex/config.toml -- the wrong file --
* even though hooks.json is present. The test asserts the correct
* single-target behavior, so it is RED on unpatched code.
*
* WHY RED:
* The PRIMARY assertion below checks that the plan does NOT list
* config.toml as a hook target for Codex. On current code the plan
* always records "hook" -> config.toml regardless of hooks.json, so the
* assertion ASSERT_NULL(strstr(json, "\"hook\"")) combined with the check
* that config.toml appears ONLY as a config path (not a hook) fails.
*
* Concretely: the JSON will contain a hooks_planned entry with
* "config.toml" in the path field, which the test asserts must NOT be
* there. ASSERT_NULL(config_toml_as_hook) fires -> RED.
*
* WHAT MAKES CODEX "DETECTED":
* cbm_detect_agents() sets agents.codex = dir_exists("~/.codex").
* Creating the directory ~/.codex is sufficient for detection.
* Creating ~/.codex/hooks.json in addition signals the JSON representation
* is already in use and is the trigger for the correct single-target behavior.
*
* FIX LOCATION (after this test is written):
* install_cli_agent_configs() in src/cli/cli.c:
* - Before choosing the hook target path for Codex, check whether
* ~/.codex/hooks.json exists.
* - If it does, pass that path to cbm_upsert_codex_session_hooks_json()
* (or equivalent JSON-format writer) and update plan_record accordingly.
* - Only fall back to config.toml when hooks.json does not exist.

*
* Oracle: cbm_build_install_plan_json(home, binary) -- dry-run plan, no writes.
*
* Assertion (correct behavior that the bug violates):
* The hooks_planned array for Codex CLI must reference hooks.json, NOT
* config.toml. Specifically: the plan JSON must NOT contain a hooks_planned

*
* RED condition on unpatched code:

*
* ROOT CAUSE (src/pipeline/fqn.c, cbm_project_name_from_path, lines ~341-348):

* unsigned char c = (unsigned char)path[i];
* bool safe = (c >= 'a' && c <= 'z') || ... || c == '-';
* if (!safe) path[i] = '-';
*
* UTF-8 encodes each CJK code-point as 3 consecutive bytes, all with
* values >= 0x80 (> 127). Every one of those bytes fails the safe-char
* test and is rewritten to '-'. The subsequent dash-collapse pass then
* folds the run of dashes from a CJK segment into a single '-', and the
* leading/trailing trim can erase it entirely if it was the final segment.
*
* For the exact path from the issue report:
* Input: "/Users/yunxin/Desktop/开发/后端/信租风控通后端"
* Buggy: "Users-yunxin-Desktop" (all three CJK segments stripped)
* Correct: result MUST contain something beyond "Users-yunxin-Desktop"
* and MUST NOT be empty. Whether the fix preserves the raw
* UTF-8 bytes ("开发"), percent-encodes them ("%E5%BC%80%E5%8F%91"),
* or uses another scheme is left to the implementer — this test
* pins the invariants:
* (a) non-NULL and non-empty result
* (b) for a path whose last segment is purely CJK, the output
* is LONGER than the result produced from the ASCII-only
* prefix of that same path (proving the CJK segment
* contributes something rather than collapsing to nothing)

// repro_issue581.c -- Reproduce-first case for OPEN bug #581.
//
// Issue: #581 -- "Memory leak: process grows to 50+ GB virtual memory over
// hours/days, crashes Windows"
// https://github.com/DeusData/codebase-memory-mcp/issues/581
//
// OBSERVED BEHAVIOUR:
// codebase-memory-mcp in stdio MCP server mode grows from ~12 MB working
// set to 50-107 GB virtual memory over 12-48 hours while the agent issues
// repeated queries (search_graph, query_graph, get_architecture, etc.).
// The reporter confirmed auto_index=false, so indexing is NOT the growth
// path -- the leak occurs purely from query/read operations.
//
// ROOT-CAUSE HYPOTHESIS (two-part):
//
// 1. SQLite WAL file: every query-only store open uses WAL journal mode
// (configure_pragmas, store.c:343) and mmap_size=64 MB
// (store.c:355-358). The WAL file accumulates un-checkpointed frames
// on every write-side flush (which happens from other operations even
// on a "read-only" query session because SQLite WAL readers also
// participate in the WAL protocol). The only checkpoint in the MCP
// event loop is SQLITE_CHECKPOINT_PASSIVE, which never ftruncates
// (mcp.c:869). Over thousands of operations the WAL grows without
// bound, with each page mapped via mmap into virtual address space.
//
// 2. mimalloc page retention: cbm_mem_collect() is called after
// index_repository (mcp.c:2866, 4616) and after delete_project
// (mcp.c:1860), but NEVER after query operations. mimalloc retains
// freed arena pages in its internal free-lists so they show up as
// committed virtual memory (visible on Windows as "commit charge")
// even after the query result is freed.
//
// The combination -- SQLite WAL mapped pages + mimalloc retained pages
// not returned to OS -- accumulates monotonically across thousands of
// query iterations without any compaction trigger.
//
// BOUNDED REPRODUCTION STRATEGY:
// Repeat a single MCP query tool call (search_graph) N=150 times against
// a small indexed project. Measure current RSS (not peak) at warmup
// (iteration 10) and at the end (iteration 150). Assert that end RSS is
// not more than LEAK_FACTOR x warmup RSS.
//
// The real-world leak is 50 GB over hours (~thousands of operations).
// Per-query accumulation is therefore large but the signal over 150
// iterations is proportionally small. We choose a generous threshold
// (3.0x) so a truly bounded implementation passes easily, while a
// genuinely leaking implementation that retains ~10-100 kB per query
// accumulates enough to exceed 3x warmup after 150 iterations (at
// 10 kB/call on a 30 MB baseline: 30 MB + 1.5 MB = 1.05x -- borderline).
//
// IMPORTANT CAVEATS / FLAKINESS NOTES:
//
// (a) RSS MEASUREMENT: we use cbm_mem_rss() (src/foundation/mem.c) which
// calls mi_process_info() for current RSS, or falls back to
// /proc/self/statm (Linux), mach_task_basic_info.resident_size (macOS),
// or GetProcessMemoryInfo.WorkingSetSize (Windows). This is CURRENT
// RSS, not peak -- suitable for detecting steady-state growth.
//
// (b) ASan BUILD PITFALL: the repro runner uses ASAN_OPTIONS=detect_leaks=0,
// so LSan won't catch this class of leak here (mimalloc/WAL accumulated
// pages are not classically leaked -- they are reachable but never freed).
// This test is an RSS-growth test, not a LSan test. ASan instrumentation
// inflates per-allocation overhead ~3x; iteration count (150) is chosen
// conservatively to stay well within CI time budgets even with ASan.
//
// (c) THRESHOLD 3.0x: the warmup RSS includes the full SQLite page cache
// and mimalloc initial arenas. On an 8-core machine warmup may be
// 50-100 MB; 3x would be 150-300 MB, achievable with a bad leak rate of
// ~1 MB/query over 150 queries. On a FIXED implementation the end RSS
// should be close to 1.0-1.2x warmup (GC cycle, small jitter).
// If this test produces a false FAIL on a correct implementation (warmup
// RSS is very small, e.g. 5 MB, and allocator variance causes spike), the
// threshold can be increased to 4x or the warmup moved later; this is
// documented as a known-fragile point.
//
// (d) LINUX-ONLY ALTERNATIVE: if cbm_mem_rss() returns 0 (e.g. MI_OVERRIDE=0
// without the OS fallback compiled), the test falls back to reading
// /proc/self/statm directly below. On macOS and Windows cbm_mem_rss()
// is expected to return non-zero. If all RSS readings are zero the test
// is declared inconclusive and PASSES to avoid false failures (the
// growth assertion requires reliable RSS readings).
//
// FIX LOCATION (not implemented here -- this test must stay RED until fixed):
// Two complementary fixes are needed:
// 1. src/mcp/mcp.c, cbm_mcp_server_run event loop (or after each tool call
// in cbm_mcp_handle_tool): periodically call
// sqlite3_wal_checkpoint_v2(..., SQLITE_CHECKPOINT_TRUNCATE, ...)
// and cbm_mem_collect() after query bursts (e.g. every N=50 calls or
// after exceeding a RSS threshold via cbm_mem_over_budget()).
// 2. src/mcp/mcp.c, cbm_mcp_server_evict_idle: on idle eviction, call
// cbm_mem_collect() so mimalloc returns pages to the OS, matching the
// same pattern used after index_repository.
//

/*
* repro_issue607.c -- Reproduce-first / regression guard for bug #607.
*
* Issue #607: "installing again via install script is dark pattern:
* 'rebuild index' message followed by delete index action"
*
* ORIGINAL DESTROYING CODE PATH (pre-fix):
* src/cli/cli.c cbm_cmd_install() printed
* "Found %d existing index(es) that must be rebuilt:\n"
* then called cbm_remove_indexes(home) which unlinked every .db and NEVER
* rebuilt. The word "rebuilt" implied preservation; the action was deletion.
* The user's indexed graph was silently, irrecoverably destroyed.
*
* APPROVED FIX (#607):
* The install-time index handling was extracted into a testable helper:
*
* int cbm_install_handle_existing_indexes(const char *home,
* bool reset, bool dry_run);
*
* Default (reset=false): PRESERVE the indexes. The helper prints an honest
* "Keeping them" message + lists them and returns 1 WITHOUT deleting
* anything. Deletion was never a schema requirement (the store uses
* CREATE TABLE IF NOT EXISTS, no migrations); re-indexing after install
* picks up extraction improvements without destroying data.
*
* Opt-in (reset=true, via `install --reset-indexes`): keep the original
* prompt-and-delete behaviour with honest "Delete" wording.
*
* WHAT THIS TEST ASSERTS (retargeted to the new behaviour):
* 1. preserves_index: after the DEFAULT path
* cbm_install_handle_existing_indexes(home, reset=false, dry_run=false)
* the index DB MUST still exist on disk.
* - RED before the fix: the helper did not exist / install deleted the
* DB, so the file was gone and the ASSERT_TRUE fired.
* - GREEN after the fix: the default path never unlinks, the file
* remains, the assertion holds.
* 2. reset_deletes: the explicit opt-in path
* cbm_install_handle_existing_indexes(home, reset=true, dry_run=false)
* MUST still delete the DB (proving the destroy primitive is reachable
* only behind the explicit flag). The prompt auto-answers "yes" via
* CBM_ASSUME_YES so the test is non-interactive.
*
* The helper is intentionally NOT declared in cli.h (internal install helper).
* cli.c is linked into the bug-repro runner ($(CLI_SRCS) is in $(PROD_SRCS)),
* so we link against it directly with an extern forward declaration below.

/*
* repro_issue627.c -- Reproduce-first case for OPEN bug #627.
*
* Issue: #627 -- "Crash when calling query_graph"
* Reporter: zbynekwinkler
*
* EXACT CRASHING INPUT (from issue body):
*
* MATCH (f:Function)
* WHERE NOT f.file_path CONTAINS 'ext'
* AND NOT f.file_path CONTAINS 'Tests'
* AND NOT f.file_path CONTAINS 'examples'
* AND NOT f.name = 'main'
* OPTIONAL MATCH (c)-[:CALLS]->(f)
* WITH f, c
* WHERE c IS NULL
* RETURN f.name, f.qualified_name, f.file_path, f.start_line
* ORDER BY f.file_path
* LIMIT 50
*
* ROOT CAUSE (src/cypher/cypher.c, expand_additional_patterns + cross_join_with_rels):
*
* When executing the second pattern "OPTIONAL MATCH (c)-[:CALLS]->(f)",
* expand_additional_patterns() (line ~4201) checks whether nodes[0] of the
* second pattern (variable "c") is already bound. "c" is a NEW variable, so
* start_bound=false and execution falls into the else branch (line ~4210).
*
* That branch calls scan_pattern_nodes() for "c" -- returning ALL nodes in the
* graph (no label filter on "c") -- and then cross_join_with_rels() to combine
* each candidate "c" with the existing "f" bindings.
*
* cross_join_with_rels() computes its pre-allocation as:
*
* malloc((*bind_count * extra_count * CYP_GROWTH_10 + 1) * sizeof(binding_t))
*
* All three operands are "int". With a graph of ~29 K nodes:
* bind_count ~ 29 000 (Function nodes from the first MATCH after WHERE)
* extra_count ~ 29 000 (ALL nodes scanned for unbound "c")
* CYP_GROWTH_10 = 10
*
* 29000 * 29000 * 10 = 8 410 000 000 -- overflows signed 32-bit int, wrapping
* to a small/negative value. cast to size_t this becomes a near-zero or
* near-SIZE_MAX value. malloc returns either NULL (OOM) or a tiny block.
* The subsequent loop writes new_bindings[new_count++] past the allocation
* boundary, corrupting the heap -> SIGSEGV / SIGABRT.
*
* A secondary bug compounds the crash: even when the multiplication does NOT
* overflow (small graphs), expand_additional_patterns() ignores the fact that
* the second pattern's terminal node "f" IS ALREADY BOUND. process_edges()
* (line ~2860) calls binding_set(&nb, "f", &found) unconditionally, overwriting
* the caller's copy of "f" with whatever node the edge leads to, instead of
* filtering to only edges whose target matches the already-bound "f". This
* produces semantically wrong results: the final WHERE c IS NULL filter and
* the RETURN f.name etc. operate on corrupted "f" bindings.
*
* EXPECTED (correct) behaviour:
* query_graph returns -- without crashing -- the list of Function nodes that
* have NO inbound CALLS edges (i.e. dead-code / uncalled functions). In our
* fixture, "orphan_func" is defined but never called; "leaf_func" is called by
* "caller_func". The correct result set must include "orphan_func" and must
* NOT include "leaf_func".
*
* ACTUAL (buggy) behaviour:
* On a graph with tens of thousands of nodes: SIGSEGV / SIGABRT (integer
* overflow in the malloc size, heap OOB write).
* On a small fixture: wrong result set due to overwritten "f" bindings; the
* assertion that "orphan_func" appears in the result and "leaf_func" does not
* fails.
*
* WHY RED on current code:
* - The fork detects a crash signal (WIFSIGNALED) if it occurs.
* ASSERT_FALSE(WIFSIGNALED(st)) fires when the child is killed by a signal.
* - Even without a crash signal the result-content assertion is RED: because
* expand_additional_patterns() misbinds "f", the query does not correctly
* identify uncalled functions. "orphan_func" may be absent or "leaf_func"
* may be present in the response, causing one of the content assertions to
* fail -> RED.
*
* Fix location (NOT implemented here):
* src/cypher/cypher.c -- expand_additional_patterns() must detect when the
* TERMINAL node of the additional pattern is already bound (here "f") and drive
* the join from that side (inbound edge scan from f), not by scanning all nodes
* for "c". Additionally, process_edges() must check whether to_var is already
* bound and, if so, only emit a match when the found node's id equals the
* already-bound node's id. The malloc in cross_join_with_rels() must use
* size_t arithmetic (not int) to avoid the overflow.

/*
* repro_issue787.c -- Reproduce-first / regression guard for bug #787.
*
* Issue #787: "Nondeterministic Java USAGE-edge misattribution across
* same-package files — USAGE sources vary per run"
*
* ROOT CAUSE (introduced by PR #667, merge commit 36d83280):
* PR #667 switched Java/Go module QNs from filename-stem-based
* ("proj.pkg.OwnerController") to DIRECTORY-based ("proj.pkg"), so all
* files in the same Java package share a single module QN. This QN also
* collides with the pipeline's Folder node for that directory.
*
* When a source-node finder (find_enclosing_node in pass_usages.c,
* find_source_node in pass_parallel.c, calls_find_source in pass_calls.c)
* resolves a CLASS-LEVEL usage (e.g., a field type reference
* `private IRepository repo;`), the enclosing_func_qn equals the shared
* directory module QN. Looking that QN up in the graph buffer returns the
* ONE Folder/Project node shared by every file in the package. That shared
* node's file_path was clobbered by each file's always-emitted Module def —
* through TWO code paths:
* - sequential: cbm_gbuf_upsert_node updated name/file_path/range in
* place (its #667 guard only protected the label);
* - parallel: merge_update_existing applied unconditional "src wins"
* when merging worker-local gbufs, even relabelling the Folder node to
* Module — and worker merge ORDER varies per run (the race flavor).
* USAGE edges from all same-package class-level references then share a
* single source node whose file_path is whichever file won the last write.
*
* Spring-petclinic oracle:
* MATCH (c {name:'OwnerRepository'})<-[r:USAGE]-(m) RETURN m.file_path
* should yield exactly 7 distinct files; HEAD (dcf98dc) returns 4-6 with
* bogus entries varying per run.
*
* FIX (three co-ordinated parts):
* 1. graph_buffer.c cbm_gbuf_upsert_node: a Module def colliding with a
* Project/Folder node no longer updates ANY field (was: label only).
* 2. graph_buffer.c merge_update_existing: same guard on the parallel
* worker-gbuf merge path.
* 3. pipeline finders (pass_usages/pass_parallel/pass_calls): a lookup that
* lands on a structural directory container (Folder/Project — see
* cbm_pipeline_node_is_dir_container) is treated as a miss, falling
* through to the per-file File node, so every file's class-level usages
* attribute to that file's unique File node.
*
* FIXTURE DESIGN (minimal spring-petclinic analog):
* Package owner/ — three Java files:
* IRepository.java defines interface IRepository (the used type)
* ServiceA.java field `IRepository repo;` (class-level USAGE)
* ServiceB.java field `IRepository repo;` (class-level USAGE)
* Package web/ — one Java file:
* WebController.java field `IRepository repo;` (cross-package USAGE)
*
* Correct USAGE edges to IRepository must source from EXACTLY:
* owner/ServiceA.java, owner/ServiceB.java, web/WebController.java
* (3 distinct source files, each appearing exactly once).
*
* Pre-fix: owner/ServiceA.java and owner/ServiceB.java share the same
* source node (the "proj.owner" Folder/Module node), so the query returns
* at most 2 distinct file_paths (and one of the two is random).
* Post-fix: each file gets its own source → 3 distinct, stable file_paths.
*
* WHY RED on buggy HEAD:
* The stability assertion (same source set across N runs) fires because the
* shared Folder node's file_path changes between indexing passes (different
* file write orders can produce different results each run). The exactness
* assertion (set equals the expected three files) fires because the owner/
* package's two callers are conflated into one node whose file_path is
* whichever of ServiceA.java / ServiceB.java was extracted last.
*
* NOTE: this test uses N=5 independent full-pipeline index+query rounds so
* that any ordering-based nondeterminism has several opportunities to
* surface. Each round opens a fresh in-memory project (different tmpdir →
* different project name → completely isolated store).

* repro_issue842.c -- Reproduce-first / regression guard for bug #842.
*
* Issue #842: "graph: same clobber class as #787 in env-access CONFIGURES
* sources and resolve_file_throws"
*
* Follow-up disclosed during #828's review (stable USAGE-edge ownership,
* #787): #828 fixed three source-node finders (find_enclosing_node in
* pass_usages.c, find_source_node in pass_parallel.c, calls_find_source in
* pass_calls.c) so a class-level construct's enclosing-QN lookup that lands
* on the shared Folder/Project node (directory-module languages, Java/Go)
* falls back to the per-file File node instead of conflating every
* same-package file onto one source. #828 deliberately left two adjacent
* direct enclosing-QN lookups out of scope:
*
* 1. create_env_configures_for_file (pass_definitions.c) — CONFIGURES edge
* source for an env-var access.
* 2. resolve_file_throws (pass_parallel.c) — THROWS/RAISES edge source for
* a thrown/raised exception.
*
* Both called cbm_gbuf_find_by_qn(enclosing_func_qn) directly, with no guard
* against the lookup landing on a Folder/Project node — the exact #787 root
* cause, just unguarded at two more sites.
*
* FIXTURE: two directory-module languages, one per call site, both exercising
* the same "no enclosing function -> enclosing_func_qn falls back to the
* MODULE QN" condition (helpers.c:900-902), which for a directory-based-module
* language collides with the shared package Folder node's QN:
*
* - THROWS: two same-package Java files (owner/ServiceA.java,
* owner/ServiceB.java), each throwing a shared exception type from a
* static initializer block (no enclosing method/constructor).
* - CONFIGURES: two same-package Go files (goenv/service_a.go,
* goenv/service_b.go), each reading the same env var in a package-level
* var declaration (no enclosing function). Go was used here instead of
* Java because Java's env-access detection (System.getenv) is separately
* broken -- extract_env_key_from_call reads a "function" field that
* Java's method_invocation node doesn't have (it uses "object"/"name"
* instead), so no EnvVar node is ever created for Java. That is a
* pre-existing, unrelated bug in the extraction layer, out of scope here.
*
* Correct THROWS sources targeting the ConfigException Class node, and
* CONFIGURES sources targeting the DB_URL EnvVar node, must each be exactly
* two distinct files.
*
* RED on unfixed HEAD: both same-package files collapse onto the single
* shared Folder/Module node for their package, so each query returns at most
* 1 distinct source instead of 2. Confirmed empirically that this only
* reproduces on resolve_file_throws's parallel (>MIN_FILES_FOR_PARALLEL=50
* files) worker-merge path -- the small sequential fixture already attributes
* correctly even on unfixed HEAD, so the THROWS test pads with 60 inert
* same-package filler classes (see build_parallel_fixture) to force that
* path, mirroring #787's own two-fixture (sequential + parallel) precedent.
* create_env_configures_for_file's CONFIGURES bug, by contrast, reproduces on
* the small sequential fixture already, so the CONFIGURES test needs no
* padding.

/*
* repro_issue964.c — Reproduce-first case for OPEN bug #964.
*
* Issue: #964 — "C/C++ #include not mapped as IMPORTS edges — expected or a
* bug?" (triaged as a bug: header files look disconnected; the reporter's
* zero-inbound query returns 194 of 214 files on a PlatformIO project).
*
* Root cause (deeper than the report guesses):
* cbm_pipeline_fqn_compute (src/pipeline/fqn.c) strips the file extension,
* so a header and its same-stem source collide on BOTH derived QNs:
* NodeController.h -> module "proj.NodeController",
* file "proj.NodeController.__file__"
* NodeController.cpp -> module "proj.NodeController",
* file "proj.NodeController.__file__"
* Node upserts match by QN, so the header's File node is merged into the
* source's — the header has NO node of its own in the graph at all. The
* `#include "NodeController.h"` import then resolves to the shared module
* (named after the .cpp), and the header can never receive an inbound
* IMPORTS edge. Headers without a same-stem sibling keep a node but the
* include-edge targeting still lands on the module, not the header file.
*
* NOTE: the module-QN unification itself is (at least partly) load-bearing
* for C/C++ — header declarations and source definitions sharing a module
* QN is what lets cross-file call resolution join them. The fix must give
* headers their own FILE identity + point include edges at it WITHOUT
* splitting the shared module QN. Both File-node creation sites (pipeline.c
* full build; pipeline_incremental.c changed-file re-creation) must agree,
* and the incremental site is concurrently being fixed by PR #995 (#994) —
* implement this fix on top of that landing, never in parallel with it.
*
* Expected (correct) behaviour:
* 1. NodeController.h has its own File node (distinct from the .cpp's).
* 2. main.cpp's `#include "NodeController.h"` produces an IMPORTS edge
* whose target is the HEADER's node, so the header is not disconnected.
*
* Why RED on current code: the header's File node does not exist (merged by
* QN collision), so both assertions fail.

/*
* repro_lsp_c_cpp.c — EXHAUSTIVE per-LSP-pass invariant suite for the C/C++
* hybrid LSP (internal/cbm/lsp/c_lsp.c).
*
* WHAT THIS ASSERTS — the LSP RESOLUTION CONTRACT, one invariant per strategy.
* The C/C++ cross resolver resolves each call via a specific STRATEGY and tags
* the resulting CALLS edge in its properties_json with
* "strategy":"lsp_<name>"
* (see c_emit_resolved_call, c_lsp.c:3287-3296; every emit site passes a
* literal "lsp_..." string). Each strategy keys on a precise C++ construct.
* This suite builds the MINIMAL fixture that exercises exactly one strategy,
* indexes it through the full production pipeline, and asserts TWO things:
* (a) callable-sourcing — the inner call is sourced at a Function/Method
* node, never at a Module/File node (inv_count_calls_by_source →
* module_sourced == 0). A Module-sourced call is the #554 attribution
* bug; this is the broad correctness floor.
* (b) strategy-presence — some CALLS edge carries "lsp_<strategy>" in its
* properties_json (inv_edge_has_strategy). This is the PRECISE per-pass
* invariant: it proves that exact resolution path fired and survived
* into the graph.
*
* RED vs GREEN — this is a STATUS BOARD, not a pass/fail gate (runs only under
* make test-repro / bug-repro.yml, never the branch-protection ci-ok gate):
* - GREEN = the LSP strategy works end-to-end = a permanent regression
* guard that it keeps working.
* - RED = the strategy is dropped, or the call lands Module-sourced, or
* the rescue is discarded. Either way the per-pass TEST DOCUMENTS
* the exact gap for the eventual fixer.
*
* TIE TO repro_invariant_lsp_rescue.c — that file pins the MECHANISM by which
* these can silently fail: cbm_pipeline_find_lsp_resolution
* (src/pipeline/lsp_resolve.h:65) joins each LSP-resolved call to the
* tree-sitter call by EXACT caller-QN string equality. When tree-sitter's
* enclosing-func walk falls back to the MODULE QN (common for out-of-line
* method bodies, #554) but the LSP built the real method QN, the strcmp never
* matches, the LSP rescue is discarded, and the edge stays Module-sourced
* with a registry strategy — NEVER an "lsp_" strategy. So a strategy that is
* correctly EMITTED by c_lsp.c can still be ABSENT from the graph here: the
* exact-QN join suppresses it. Whenever a strategy below is RED, suspect that
* join first (an in-line / free-function fixture sidesteps it; an out-of-line
* method fixture triggers it).
*
* STRATEGY INVENTORY — every literal "lsp_..." emitted by c_lsp.c, grepped from
* the source (grep '"lsp_' internal/cbm/lsp/c_lsp.c), with its keying site:
* lsp_direct (c_lsp.c:3650) free/global function call f()
* lsp_implicit_this (c_lsp.c:3655) member calls sibling member, no this->
* lsp_scoped (c_lsp.c:3489/3509/3525) Ns::f() / Class::g()

* lsp_virtual_dispatch (c_lsp.c:3401) base*->virt(), override found on derived
* lsp_base_dispatch (c_lsp.c:3403) inherited method, no derived override
* lsp_smart_ptr_dispatch (c_lsp.c:3409) std::unique_ptr<T>->method()
* lsp_template (c_lsp.c:3576) f<T>(args) explicit template call
* lsp_template_instantiation(c_lsp.c:393) template<T> body t.m() resolved at instantiation
* lsp_func_ptr (c_lsp.c:3605) call via tracked function pointer
* lsp_dll_resolve (c_lsp.c:3605) call via fp whose target is external.* (DLL)
* lsp_operator (c_lsp.c:3624/3789/3821/3845/3889) overloaded operator use
* lsp_constructor (c_lsp.c:3641/3715/3745) new Foo() / Foo x(args)
* lsp_destructor (c_lsp.c:3765) delete p (p : Foo*)
* lsp_copy_constructor (c_lsp.c:3922) Foo a = b; (b : Foo)
* lsp_conversion (c_lsp.c:3946) if (obj) with operator bool
* lsp_adl (c_lsp.c:3674) unqualified call resolved by ADL

/*
* repro_lsp_go_py.c — EXHAUSTIVE per-LSP-pass invariant suite for the Go and
* Python hybrid LSPs (internal/cbm/lsp/go_lsp.c, internal/cbm/lsp/py_lsp.c).
*
* WHAT THIS ASSERTS — the LSP RESOLUTION CONTRACT, one invariant per strategy.
* Each cross resolver resolves a call via a specific STRATEGY and tags the
* resulting CALLS edge in its properties_json with
* "strategy":"lsp_<name>"
* (Go: emit_resolved_call, go_lsp.c:1084-1094; Python: py_emit_resolved_call,
* py_lsp.c:322-353; every emit site passes a literal "lsp_..." string). Each
* strategy keys on a precise Go/Python construct. This suite builds the
* MINIMAL fixture that exercises exactly one strategy, indexes it through the
* full production pipeline, and asserts TWO things:
* (a) callable-sourcing — the inner call is sourced at a Function/Method
* node, never at a Module/File node (inv_count_calls_by_source →
* module_sourced == 0). A Module-sourced call is the #554 attribution
* bug; this is the broad correctness floor.
* (b) strategy-presence — some CALLS edge carries "lsp_<strategy>" in its
* properties_json (inv_edge_has_strategy). This is the PRECISE per-pass
* invariant: it proves that exact resolution path fired and survived
* into the graph.
*
* RED vs GREEN — this is a STATUS BOARD, not a pass/fail gate (runs only under
* make test-repro / bug-repro.yml, never the branch-protection ci-ok gate):
* - GREEN = the LSP strategy works end-to-end = a permanent regression
* guard that it keeps working.
* - RED = the strategy is dropped, or the call lands Module-sourced, or
* the rescue is discarded. Either way the per-pass TEST DOCUMENTS
* the exact gap for the eventual fixer.
*
* TIE TO repro_invariant_lsp_rescue.c — that file pins the MECHANISM by which
* these can silently fail: cbm_pipeline_find_lsp_resolution joins each
* LSP-resolved call to the tree-sitter call by EXACT caller-QN string
* equality. When tree-sitter's enclosing-func walk falls back to the MODULE
* QN but the LSP built the real method QN, the strcmp never matches, the LSP
* rescue is discarded, and the edge stays Module-sourced with a registry
* strategy — NEVER an "lsp_" strategy. So a strategy that is correctly
* EMITTED by the LSP can still be ABSENT from the graph here: the exact-QN
* join suppresses it. Whenever a strategy below is RED, suspect that join
* first (a same-file in-function fixture sidesteps it).
*
* GO STRATEGY INVENTORY — every literal "lsp_..." emitted by go_lsp.c, grepped
* from the source (grep '"lsp_' internal/cbm/lsp/go_lsp.c), with its keying
* site:
* lsp_direct (go_lsp.c:1139/1265) pkg.Func() or local f()
* lsp_type_dispatch (go_lsp.c:1161) obj.Method() on a concrete
* value type (receiver type
* == method receiver type)
* lsp_embed_dispatch (go_lsp.c:1164) embedded-struct promoted
* method (method receiver
* type != outer type)
* lsp_interface_resolve (go_lsp.c:1226) call through an interface
* with EXACTLY ONE concrete
* implementer in the project
* lsp_interface_dispatch (go_lsp.c:1236) call through an interface
* with 0 or >=2 implementers
* (generic fallback)
* lsp_strategy_cross_file (go_lsp.c:2925) cross-file fast-resolve of
* an unresolved call against
* the global registry
* lsp_unresolved (go_lsp.c:1103) fallback marker for an
* unresolved call
*
* PYTHON STRATEGY INVENTORY — every literal "lsp_..." emitted by py_lsp.c
* (grep '"lsp_' internal/cbm/lsp/py_lsp.c), with its keying site:
* lsp_direct (py_lsp.c:1631) module-local f()
* lsp_constructor (py_lsp.c:1624) ClassName() where the name is a
* NAMED type in scope
* lsp_method (py_lsp.c:1731) obj.method() on a NAMED-typed
* receiver (covers self.other())
* lsp_super (py_lsp.c:1693) super().method() resolved on a
* base class (non-__init__)
* lsp_super_init (py_lsp.c:1702) super().__init__()
* lsp_module_attr (py_lsp.c:1719) mod.func() after `import mod`,
* func is a registered symbol
* lsp_module_attr_unresolved(py_lsp.c:1724) mod.func() where func is NOT a
* registered symbol of the module
* lsp_dict_dispatch (py_lsp.c:1662) funcs["key"]() dispatch table
* lsp_operator_dunder (py_lsp.c:2120) a + b where a is a NAMED type
* defining __add__
* lsp_builtin (py_lsp.c:1637) print()/len()/... a builtins
* symbol (needs typeshed registry)
* lsp_builtin_constructor (py_lsp.c:1643) str()/list()/... a builtins type
* lsp_builtin_method (py_lsp.c:1741) "x".upper() — method on a
* builtin-typed receiver
* lsp_generic_method (py_lsp.c:1753) method on a TEMPLATE-typed
* receiver (list[T]/dict[K,V])
* lsp_method_union (py_lsp.c:1778) method on a UNION-typed receiver
* with exactly one matching member
*
* EXPECTED-RED NOTES (documented gaps, not suite bugs):
* - lsp_builtin / lsp_builtin_constructor / lsp_builtin_method /
* lsp_generic_method: resolution requires the builtins/typeshed registry
* ("builtins.print", "builtins.str.upper", ...) to be loaded into the
* per-file registry. A single-file fixture has no typeshed, so these are
* expected ABSENT (RED) — they document that the builtins-registry binding
* the single-file harness can't synthesize is required.
* - lsp_method_union: needs a union-typed receiver (e.g. `x: A | B`) where
* exactly one member defines the method; the annotation must resolve both
* members to in-file NAMED types. Documented if it does not surface.
*
* NOTE: line comments only inside this header (no nested block comments, per
* coding rules).

/*
* repro_lsp_java_cs.c — EXHAUSTIVE per-LSP-pass invariant suite for the Java
* (internal/cbm/lsp/java_lsp.c) and C# (internal/cbm/lsp/cs_lsp.c) hybrid LSPs.
*
* This MIRRORS repro_lsp_c_cpp.c: same shared assert_lsp_strategy runner, same
* two invariants per strategy (callable-sourcing floor + strategy-presence),
* one TEST per (language, strategy), a single SUITE(repro_lsp_java_cs).
*
* WHAT THIS ASSERTS — the LSP RESOLUTION CONTRACT, one invariant per strategy.
* Each cross resolver resolves a call via a specific STRATEGY and tags the
* resulting CALLS edge in its properties_json with "strategy":"<name>" (Java:
* java_emit_resolved, java_lsp.c; C#: cs_emit_resolved, cs_lsp.c). Each
* strategy keys on a precise language construct. This suite builds the MINIMAL
* fixture that exercises exactly one strategy, indexes it through the full
* production pipeline, and asserts TWO things:
* (a) callable-sourcing — the inner call is sourced at a Function/Method
* node, never at a Module/File node (inv_count_calls_by_source ->
* module_sourced == 0). A Module-sourced call is the #554 attribution
* bug; this is the broad correctness floor.
* (b) strategy-presence — some CALLS edge carries the exact strategy string
* in its properties_json (inv_edge_has_strategy). This is the PRECISE
* per-pass invariant: it proves that exact resolution path fired and
* survived into the graph.
*
* CRITICAL NAMING DIFFERENCE FROM C/C++ AND JAVA — C# strategies are NOT
* "lsp_*". The C/C++ resolver and the Java resolver both emit "lsp_<name>"
* strings, but cs_lsp.c emits "cs_<name>" strings (cs_emit_resolved sites,
* cs_lsp.c:1468-1604). The task brief assumed C# emitted lsp_interface_resolve
* / lsp_method_dispatch / lsp_static_import — those are JAVA strategies; C#
* has its own "cs_" vocabulary. The fixtures below use the ACTUAL strings
* grepped from each source, not the assumed ones.
*
* RED vs GREEN — this is a STATUS BOARD, not a pass/fail gate (runs only under
* make test-repro / bug-repro.yml, never the branch-protection ci-ok gate):
* - GREEN = the LSP strategy works end-to-end = a permanent regression
* guard that it keeps working.
* - RED = the strategy is dropped, or the call lands Module-sourced, or
* the rescue is discarded. Either way the per-pass TEST DOCUMENTS
* the exact gap for the eventual fixer.
*
* Like repro_invariant_lsp_rescue.c, a strategy correctly EMITTED by the
* resolver can still be ABSENT here if cbm_pipeline_find_lsp_resolution
* (src/pipeline/lsp_resolve.h) fails to join the LSP-resolved call to the
* tree-sitter call by exact caller-QN equality (#554). The in-line / method
* fixtures below keep the call inside a real callable so the join target is a
* method QN, not the module QN.
*
* JAVA STRATEGY INVENTORY — every literal "lsp_..." emitted by java_lsp.c,
* grepped from source (grep '"lsp_' internal/cbm/lsp/java_lsp.c):
* lsp_type_dispatch (1823/1923) obj.method() / bare call on own class

/*
* repro_lsp_kt_php_rust.c — EXHAUSTIVE per-LSP-pass invariant suite for the
* Kotlin, PHP and Rust hybrid LSPs
* (internal/cbm/lsp/kotlin_lsp.c, php_lsp.c, rust_lsp.c).
*
* MIRRORS repro_lsp_c_cpp.c exactly: same shared assert_lsp_strategy runner,
* same two invariants per (lang,strategy) — (a) inv_count_calls_by_source
* module_sourced == 0 and a callable-sourced CALLS edge exists, and (b)
* inv_edge_has_strategy(store, project, "<strategy>"). One TEST per
* (lang,strategy); SUITE(repro_lsp_kt_php_rust) at the bottom.
*
* WHAT THIS ASSERTS — the LSP RESOLUTION CONTRACT, one invariant per strategy.
* Each hybrid LSP resolves a call via a specific STRATEGY and tags the
* resulting CALLS edge in its properties_json with a literal strategy string.
* The minimal fixture exercises exactly one strategy, indexes it through the
* full production pipeline (language picked from the file extension: ".kt" →
* Kotlin, ".php" → PHP, ".rs" → Rust), and asserts:
* (a) callable-sourcing — the inner call is sourced at a Function/Method
* node, never at a Module/File node (the #554 attribution bug).
* (b) strategy-presence — some CALLS edge carries the strategy literal in
* its properties_json (inv_edge_has_strategy, substring match).
*
* STRATEGY-STRING NOTE — the assertion string is the ACTUAL literal each LSP
* emits (substring-matched by inv_edge_has_strategy), NOT a uniform
* "lsp_<name>" mould:
* - Kotlin emits "lsp_kt_*" (kt_emit_resolved, kotlin_lsp.c:299).
* - PHP emits mostly "php_*" plus "lsp_unresolved" (emit_resolved /
* emit_unresolved, php_lsp.c:1238/1251). The "php_*" literals are the
* real keys — the reference suite's "lsp_<strategy>" shorthand does not
* apply to PHP, so the assertions below use the php_* literals verbatim.
* - Rust emits "lsp_*" (rust_emit_resolved_call, rust_lsp.c).
*
* RED vs GREEN — STATUS BOARD, not a pass/fail gate (runs only under
* make test-repro / bug-repro.yml, never the branch-protection ci-ok gate):
* - GREEN = the strategy works end-to-end = a permanent regression guard.
* - RED = the strategy is dropped, lands Module-sourced, or never reaches
* the graph. The TEST documents the exact gap for the fixer.
*
* RUST CROSS-LSP IS NOT WIRED (documented gap). src/pipeline/pass_lsp_cross.c
* has NO CBM_LANG_RUST case in either cbm_pxc_has_cross_lsp (lines 282-298)
* or the cbm_pxc_run_one dispatch (lines 372-407). Go/C/C++/Python/PHP/Java/
* Kotlin are wired; Rust is absent. So rust_lsp.c can EMIT every strategy
* below, but those resolved calls never reach pass_lsp_cross → never become
* tagged CALLS edges in the graph. Every Rust strategy test is therefore
* expected RED until rust_lsp.c is wired into the pipeline. We assert the
* CORRECT (resolved) outcome anyway, per the reproduce-first contract: the
* red test is the durable record of the gap and turns GREEN the moment Rust
* is wired and resolving correctly.
*
* SKIPPED STRATEGIES (documented, not tested):
* Kotlin:
* - lsp_kt_safe — listed in the kotlin_lsp.c header comment (line 32) but
* NEVER emitted: grep for the literal finds only the
* header. A `obj?.foo()` safe call routes through the
* generic navigation handler and emits "lsp_kt_method"
* (kt_eval_navigation_expression_type does not branch on
* `?.` vs `.`). No fixture can produce "lsp_kt_safe".
* - lsp_kt_import — likewise header-only (line 34), never emitted. Import
* targets surface through the top-level / method paths.
* Rust:
* - lsp_mod_decl — emitted (rust_lsp.c:4347) but DELIBERATELY Module-
* sourced: it temporarily sets enclosing_func_qn =
* module_qn so the edge is attributed to the file's
* synthetic module scope (a `mod foo;` declaration has no
* enclosing callable). It would violate invariant (a)
* (module_sourced == 0) by construction, so the shared
* runner cannot express it. Also blocked by the unwired-
* Rust gap above.
* - lsp_deref_dispatch / lsp_bound_dispatch / lsp_prelude_trait /
* lsp_short_name_unique / lsp_trait_ufcs_amb — emitted on harder-to-
* fixture paths (Deref chains, type-param bounds, prelude best-effort,
* crate-prefix short-name scan, multi-impl ambiguity). They are all also
* blocked by the unwired-Rust gap, so adding fragile fixtures for them
* buys nothing over the representative dispatch tests below; skipped.
*

/*
* repro_lsp_ts.c — EXHAUSTIVE per-LSP-pass invariant suite for the TypeScript /
* JavaScript / JSX hybrid LSP (internal/cbm/lsp/ts_lsp.c).
*
* WHAT THIS ASSERTS — the LSP RESOLUTION CONTRACT, one invariant per strategy.
* The TS cross resolver resolves each call via a specific STRATEGY and tags the
* resulting CALLS edge in its properties_json with
* "strategy":"lsp_<name>"
* (see ts_emit_resolved_call, ts_lsp.c:109-120; every concrete emit site passes
* a literal "lsp_ts..." string). Each strategy keys on a precise TS/TSX
* construct. This suite builds the MINIMAL fixture that exercises exactly one
* strategy, indexes it through the full production pipeline, and asserts TWO
* things:
* (a) callable-sourcing — the inner call is sourced at a Function/Method
* node, never at a Module/File node (inv_count_calls_by_source →
* module_sourced == 0). A Module-sourced call is the #554 attribution
* bug; this is the broad correctness floor.
* (b) strategy-presence — some CALLS edge carries "lsp_<strategy>" in its
* properties_json (inv_edge_has_strategy). This is the PRECISE per-pass
* invariant: it proves that exact resolution path fired and survived into
* the graph.
*
* RED vs GREEN — this is a STATUS BOARD, not a pass/fail gate (runs only under
* make test-repro / bug-repro.yml, never the branch-protection ci-ok gate):
* - GREEN = the LSP strategy works end-to-end = a permanent regression
* guard that it keeps working.
* - RED = the strategy is dropped, or the call lands Module-sourced, or
* the rescue is discarded. Either way the per-pass TEST DOCUMENTS
* the exact gap for the eventual fixer.
*
* TIE TO repro_invariant_lsp_rescue.c — that file pins the MECHANISM by which
* these can silently fail: cbm_pipeline_find_lsp_resolution joins each
* LSP-resolved call to the tree-sitter call by EXACT caller-QN string equality.
* When tree-sitter's enclosing-func walk falls back to the MODULE QN but the
* LSP built the real method QN, the strcmp never matches, the LSP rescue is
* discarded, and the edge stays Module-sourced with a registry strategy —
* NEVER an "lsp_" strategy. So a strategy that is correctly EMITTED by ts_lsp.c
* can still be ABSENT from the graph here: the exact-QN join suppresses it.
* Whenever a strategy below is RED, suspect that join first (a same-file
* in-function fixture sidesteps it; a cross-file fixture exercises it).
*
* STRATEGY INVENTORY — every literal "lsp_..." emitted by ts_lsp.c, grepped from
* the source (grep '"lsp_' internal/cbm/lsp/ts_lsp.c), with its keying site:
* lsp_ts_local (ts_lsp.c:2322) bare identifier call f() resolving to a
* module-local function (call_expression
* function is an `identifier`, found in the
* module registry).
* lsp_ts_method (ts_lsp.c:2284) obj.method() type-based dispatch on a
* receiver whose type is a NAMED in-file
* class (member_expression, lookup_method
* hits).
* lsp_ts_namespace (ts_lsp.c:2246) Ns.fn() where Ns is a namespace import
* (`import * as Ns from "./mod"`); the
* member_expression object is an identifier
* matching an import local name, fn resolves
* in that module's registry.
* lsp_ts_import (ts_lsp.c:2334) bare identifier call to an imported
* function (`import { helper } ...`); the
* identifier matches an import local name and
* resolves in the imported module's registry.
* lsp_ts_jsx (ts_lsp.c:2647) <Comp/> JSX element whose tag is a
* module-local component function (TSX only;
* uppercase tag, resolves via the module
* registry).
* lsp_ts_jsx_import (ts_lsp.c:2657) <Comp/> JSX element whose tag is an
* imported component (TSX only; tag matches
* an import local name → synthetic
* "<module>.<Comp>" QN). NOTE: this site
* builds the callee QN WITHOUT verifying the
* symbol exists in the registry, so it can
* emit even when the import target is absent.

* lsp_unresolved (ts_lsp.c:128) fallback marker for an unresolved call
* (ts_emit_unresolved_call, confidence 0.0).
* A 0.0-confidence unresolved entry is

*
* LANGUAGE SELECTION — the filename extension picks the language exactly as the
* production indexer does: ".ts" → CBM_LANG_TYPESCRIPT, ".tsx" → CBM_LANG_TSX.
* jsx_mode (required by resolve_jsx_element, ts_lsp.c:2620) is enabled ONLY for
* CBM_LANG_TSX (cbm.c:619, pass_lsp_cross.c:267), so the two JSX fixtures use
* ".tsx" files; the non-JSX fixtures use ".ts".
*

/*
* repro_new_cypher_limit_zero.c -- Reproduce-first case for a NEW, un-filed
* bug discovered during QA sweep (2026-06-26).
*
* BUG: `LIMIT 0` in a Cypher query does NOT return 0 rows; instead it
* returns ALL rows, treating `LIMIT 0` as equivalent to "no limit".
*
* ROOT CAUSE -- src/cypher/cypher.c, two co-located guards that conflate
* "no limit specified" (limit==-1 or limit==0 as sentinel) with
* "explicitly requested limit of zero".
*
* GUARD 1 -- rb_apply_skip_limit (~line 3095):
*
* if (limit > 0 && rb->row_count > limit) { ... rb->row_count = limit; }
*
* When limit==0 (from LIMIT 0), the condition `limit > 0` is FALSE, so
* the row count is never trimmed to zero.
*
* GUARD 2 -- execute_single RETURN path (~line 4249):
*
* rb_apply_skip_limit(rb, ret->skip,
* ret->limit > 0 ? ret->limit : max_rows);
*
* When ret->limit==0, `ret->limit > 0` is FALSE so max_rows is passed
* as the limit argument instead of 0, returning ALL rows.
*
* GUARD 3 -- with_sort_skip_limit / bindings_skip_limit (~line 3409):
*
* if (limit > 0 && *count > limit) { ... *count = limit; }
*
* Same pattern: limit==0 never triggers the trim.
*
* The root cause: the engine uses `limit == 0` as the sentinel value for
* "no LIMIT clause was specified" rather than using a distinct negative
* sentinel (e.g. -1). When the user explicitly writes `LIMIT 0`, the
* parsed value is also 0 -- indistinguishable from "unset" -- so all
* guards treat it as "no limit".
*
* EXPECTED (correct) behavior:
* `MATCH (f:Function) RETURN f.name LIMIT 0` must return 0 rows.
* In standard Cypher, LIMIT N is an upper bound; LIMIT 0 means "at most
* 0 rows", i.e., an empty result set.
*
* ACTUAL (buggy) behavior:
* All rows are returned (row_count == 4 in the standard fixture).
* ASSERT_EQ(r.row_count, 0) fires -> RED.
*
* HOW TO CONFIRM WITHOUT COMPILING:
* 1. cypher.c parse_return_or_with (~line 1665): `LIMIT N` sets
* r->limit = strtol(num->text) = 0 for `LIMIT 0`.
* 2. rb_apply_skip_limit (~line 3095): guard `if (limit > 0 ...)` --
* FALSE for limit=0 -- trimming is skipped.
* 3. execute_single return path (~line 4249): `ret->limit > 0 ?
* ret->limit : max_rows` evaluates to max_rows when limit==0, so
* the full row set is preserved.
*
* FIX LOCATION (not implemented here):
* Use a sentinel of -1 (not 0) for "LIMIT not specified" so that
* limit==0 can be distinguished as an explicit request for zero rows.
* Change the initializer in cbm_return_clause_t to use -1, update the
* parser to set limit = (int)strtol() only (already correct), and change
* all guards from `limit > 0` to `limit >= 0` (or `limit != -1`).

/*
* repro_new_py_tuple_unpack.c -- Reproduce-first case for a NEW, un-filed
* bug discovered during QA sweep (2026-06-26).
*
* BUG: Python module-level tuple-unpacking assignments silently produce no
* Variable definitions. `x, y = some_func()` is in py_var_types
* (as "assignment") but the Python branch of extract_vars_mainstream()
* only emits a def when the `left` child is a plain `identifier`. When
* `left` is a `pattern_list` (the tree-sitter node type for comma-separated
* LHS in an assignment), the guard fails silently and zero Variable defs
* are emitted for x or y.
*
* PATTERN AFFECTED:
* x, y = some_func() # left is pattern_list
* a, b, c = 1, 2, 3 # left is pattern_list
* result, err = parse(data) # common Go-style unpack in Python
*
* ROOT CAUSE -- extract_defs.c, extract_vars_mainstream(), Python case
* (~line 4068):
*
* case CBM_LANG_PYTHON: {
* TSNode left = ts_node_child_by_field_name(node, TS_FIELD("left"));
* if (!ts_node_is_null(left) && strcmp(ts_node_type(left), "identifier") == 0) {
* push_var_def(ctx, cbm_node_text(a, left, ctx->source), node);
* }
* break;
* }
*
* The guard `strcmp(ts_node_type(left), "identifier") == 0` passes only
* for single-variable assignments (`x = 1`). For `x, y = func()` the
* tree-sitter-python grammar produces `left` as a `pattern_list` node
* containing two `identifier` children. The strcmp fails -> no
* push_var_def is called -> both `x` and `y` are silently dropped.
*
* py_var_types (lang_specs.c) includes both "assignment" AND
* "augmented_assignment", so the walk_variables path DOES reach
* extract_vars_mainstream for these nodes -- the gap is purely inside
* the Python case guard.
*
* EXPECTED (correct) behavior:
* `x, y = some_func()` at module level must produce AT LEAST one
* Variable def; ideally one for `x` and one for `y`.
* `result, err = parse(data)` must produce Variable defs for `result`
* and `err`.
*
* ACTUAL (buggy) behavior:
* r->defs contains zero Variable defs for these assignments.
* ASSERT_GT(count, 0) fires -> RED.
*
* HOW TO CONFIRM WITHOUT COMPILING:
* 1. lang_specs.c: py_var_types = {"assignment", "augmented_assignment", NULL}
* -> walk_variables correctly calls extract_var_names for "assignment" nodes.
* 2. extract_defs.c extract_vars_mainstream() Python case (~4068):
* left node for `x, y = ...` is of type "pattern_list" (confirmed by
* tree-sitter-python grammar symbol sym_pattern_list = 200).
* 3. The strcmp("pattern_list", "identifier") == 0 check FAILS -> no def.
*
* FIX LOCATION (not implemented here):
* extract_defs.c extract_vars_mainstream() Python case: when left is
* "pattern_list", iterate its named children and call push_var_def for
* each child that is an "identifier".

/*
* repro_new_ts_class_field_arrow.c -- Reproduce-first case for a NEW, un-filed
* bug discovered during QA sweep (2026-06-26).
*
* BUG: TypeScript class field arrow functions are silently dropped from
* the Method definition list AND calls inside them receive the wrong
* enclosing_func_qn (the class QN instead of the method QN).
*
* PATTERN AFFECTED:
* class Foo {
* handleClick = () => {
* helper();
* };
* }
*
* This is an extremely common React/TypeScript pattern for event handlers.
*
* ROOT CAUSE -- TWO co-located defects:
*
* DEFECT A -- extract_defs.c, extract_class_methods() (~line 3578):
* The function iterates the class body's direct children. For each child it
* checks:
* cbm_kind_in_set(method_node, spec->function_node_types)
* "public_field_definition" is NOT in ts_func_types -- only
* "function_declaration", "arrow_function", "method_definition", etc. are.
* So the body-scan loop hits `continue` and the method is never emitted.
*
* The parallel path (extract_func_def, called from walk_defs when the DFS
* visits the inner "arrow_function" node) also fails: it calls
* resolve_toplevel_arrow_name() which only handles the `variable_declarator`
* and `pair` parent cases -- NOT `public_field_definition`. So it returns
* NULL and extract_func_def() returns early with no def emitted.
*
* DEFECT B -- extract_unified.c, push_boundary_scopes() / compute_func_qn():
* When the DFS cursor visits the `arrow_function` node inside
* `public_field_definition`, it IS in ts_func_types so push_boundary_scopes
* calls compute_func_qn(). compute_func_qn() calls resolve_func_name_node()
* which only handles the `variable_declarator` parent -- NOT
* `public_field_definition`. So name_node is NULL -> compute_func_qn
* returns NULL -> no SCOPE_FUNC is pushed for this arrow function.
*
* Consequence: any call inside the arrow function body runs handle_calls()
* with state->enclosing_func_qn still set to state->enclosing_class_qn
* (the class "proj.ts.Foo"), NOT the method "proj.ts.Foo.handleClick".
*
* EXPECTED (correct) behavior:
* A. cbm_extract_file must emit a Method def with name="handleClick"
* and qualified_name containing both "Foo" and "handleClick".
* B. The call to helper() inside handleClick must have
* enclosing_func_qn pointing to the handleClick method, NOT just
* the class "Foo". Specifically enclosing_func_qn must contain
* "handleClick" and must NOT equal the module QN.
*
* ACTUAL (buggy) behavior:
* A. r->defs contains no Method entry for "handleClick" -- the def is
* silently dropped. ASSERT_NOT_NULL(method_def) fires -> RED.
* B. The helper() call has enclosing_func_qn == class QN ("proj.ts.Foo"),
* not the method QN. ASSERT_NOT_NULL(strstr(enc, "handleClick")) fires
* -> RED.
*
* HOW TO CONFIRM THE BUG WITHOUT COMPILING:
* 1. extract_class_methods (extract_defs.c ~3578): iterates body children;
* line ~3620 guards on cbm_kind_in_set(method_node, spec->function_node_types);
* "public_field_definition" is absent from ts_func_types (lang_specs.c ~237)
* -> guard fails -> no Method emitted.
* 2. resolve_toplevel_arrow_name (extract_defs.c ~598): only handles
* variable_declarator and pair parents -- not public_field_definition.
* 3. resolve_func_name_node (extract_unified.c ~91): same gap for
* push_boundary_scopes scope tracking.
*
* FIX LOCATION (not implemented here):
* extract_defs.c extract_class_methods: add a peek-through for
* "public_field_definition" (similar to the decorated_definition peek),
* extract the inner arrow_function's name from the field's "name" child,
* and call push_method_def.
* extract_unified.c resolve_func_name_node: add a "public_field_definition"
* / "field_definition" parent case (similar to the variable_declarator case)
* so compute_func_qn can push a SCOPE_FUNC for the arrow function.

/*
* repro_parallel_determinism.c — RED reproduction for the parallel-indexing
* edge-loss / non-determinism bug (REAL-REPO TIER).
*
* DISCOVERED: while verifying F6 (2026-07), re-indexing the SAME corpus with the
* correct cache cleared produced DIFFERENT edge counts run-to-run when
* multi-threaded (kernel fs/xfs: 58548 / 58552 / 58557 / 58573; kernel-rust:
* 44445 / 44775 / 44857) and the multi-threaded counts trend BELOW the
* single-threaded reference (xfs ST 58573). I.e. parallel indexing both flickers
* AND drops edges vs the single-threaded graph.
*
* INVARIANT (green <=> fixed): indexing a fixed corpus is DETERMINISTIC and the
* multi-threaded graph equals the single-threaded graph exactly. This test indexes
* the corpus single-threaded (reference) then K times multi-threaded (fresh store
* each run) and asserts every MT sorted edge set equals the ST one. Comparison is
* over the SORTED (source_qn, type, target_qn) triples — NOT raw counts.
*
* WHY A REAL-REPO TIER (honest calibration record): a self-contained synthetic C
* corpus could NOT trigger the divergence in three escalating attempts —
* (1) 300 files, dense cross-file CALLS only;
* (2) 500 files, big per-function bodies (fingerprinted, nodes_with_fp=500);
* (3) 600 files, TOKEN-IDENTICAL clustered bodies (to force SIMILAR_TO edges);
* all produced a fully DETERMINISTIC graph across ST + 6 MT runs, and the
* similarity pass emitted 0 edges on synthetic C (`pass.similarity edges=0`). The
* race clearly needs real-code edge diversity/volume (real SIMILAR_TO / semantic /
* cross-file type edges) that synthetic C does not produce. Rather than ship a
* false guard (green on buggy code), this uses the smallest REAL corpus on which
* the flicker was directly observed — the kernel's fs/xfs subtree — and SKIPs when
* that corpus is absent (e.g. CI). It is RED on the dev machine where the race
* lives, which is where the fix (deferred) will be developed and guarded.
*
* SUSPECTED ROOT CAUSE (for the fixer): a race in parallel edge production/merge —
* per-worker edge-buffer merge (pass_parallel 2_merge_edge_bufs_seq), graph-buffer
* edge dedup under concurrent append (edge_by_key check-then-insert), similarity
* edge emission (symmetric SIMILAR_TO from both sides), or resolve_worker emission
* ordering. The single-threaded edge set is the reference semantics. Fix DEFERRED —
* this stays on the known-red board until the race is fixed.

/*
* repro_ts_inherited_method.c — RED reproduction: TypeScript CROSS-FILE
* INHERITED method call resolution gap (ts_lsp).
*
* THE GAP: a typed call to a method the receiver's class INHERITS from a base
* class defined in ANOTHER file is never resolved by the TS LSP:
*
* base.ts: export class Base { greet(): string { ... } }
* derived.ts: import { Base } from "./base";
* export class Derived extends Base { ... }
* export function callSite(): string {
* const d: Derived = new Derived();
* return d.greet(); <-- inherited, cross-file
* }
*
* CORRECT behaviour (asserted here, so this test is RED until fixed): a CALLS
* edge from the caller (callable-sourced, QN contains "callSite") to the BASE
* method definition (target QN suffix ".Base.greet" — mirroring the
* java/kotlin/php inherited-dispatch convention: resolution lands on the base
* class's method def, since Derived declares no `greet` and no such node can
* exist), carrying a genuine TS-LSP resolution strategy ("lsp_ts_*" in the
* edge's properties_json, per the ts_emit_resolved_call contract documented in
* repro_lsp_ts.c).
*
* WHY the strategy tag is part of the invariant: before the weak-short-name
* suppression (PR #840, recovering withdrawn #836/#835), this scenario looked
* resolved via a unique_name REGISTRY fallback — "greet" is unique in a 2-file
* fixture, so a short-name guess happened to bind the right node (a false
* green; in a real repo the same guess binds an arbitrary same-named method).
* PR #840 flipped the probe lrp_ts_s6_inherited_method
* (tests/test_lsp_resolution_probe.c) to assert that this weak edge is
* SUPPRESSED (calls == 0) — correct, but it leaves the underlying resolution
* gap without any red reproduction. THIS test is that reproduction:
* - on pre-#840 code the lucky edge exists but carries NO "lsp_ts" strategy
* -> RED (the green was never genuine);
* - on post-#840 code the weak edge is suppressed, no edge exists at all
* -> RED;
* - only genuine ts_lsp cross-file inheritance resolution turns it GREEN.
*
* ROOT-CAUSE POINTER (for the eventual fixer): ts_lsp cross-file inheritance
* resolution — internal/cbm/lsp/ts_lsp.c resolve_member_call/lookup_method
* only walks methods declared on the receiver's OWN class as registered in the
* module registry; it does not follow the (correctly extracted) INHERITS edge
* from Derived to an imported Base to find `greet` there. See PR #836/#840 and
* the S6 probe lrp_ts_s6_inherited_method for the full analysis. The INHERITS
* edge and both defs ARE in the graph (asserted below as preconditions), so a
* red here is the RESOLUTION gap, not an extraction failure.
*
* NOTE: line comments only inside this header (no nested block comments, per
* coding rules).
