feat(cfg): PDG/CFG visitors for all supported languages (#2195) (#2197)
* test(cfg): validate cfg/visitors literals + drop 3 dead TS node types
Extend the grammar-literal CI gate (test/helpers/literal-collectors.ts)
to scan cfg/visitors/*.ts, mapping each visitor file to its grammar via
the existing basename rule (c-cpp -> C/C++, csharp -> C#, java -> Java,
go -> Go, typescript -> TS). Closes the gap where the gate never
validated CFG visitor node-type literals -- the prerequisite for adding
C-family visitors safely (#2195 U1).
The newly-scanned TS visitor surfaced 3 dead literals absent from every
grammar it serves (typescript/javascript/tsx all = 0): for_of_statement
(for-of parses as for_in_statement), async_function_declaration and
async_arrow_function (async functions are function_declaration /
arrow_function + an async child). Removed them; behavior-preserving --
the cases never matched, bench --check fingerprints unchanged, TS
visitor unit tests green.

* test(cfg): language-agnostic CFG unit-test harness (#2195 U1)
Extract the grammar-agnostic engine from ts-cfg-harness into
makeCfgHarness(grammar, visitor, filePath) at test/helpers/cfg-harness.ts.
Function discovery delegates to visitor.isFunction, so the harness carries
no language-specific node-type knowledge -- each C-family visitor's unit
tests can drive the real worker-side builder against real source.
ts-cfg-harness becomes a thin TS binding re-exporting the same
parse/collectFunctions/cfgOf/cfgsOf (behavior-preserving: all 5 existing
consumers -- taint propagate/model-match/summary-harvest/taint-emit + cfg
harvest -- pass unchanged, 223 tests green). New harness.test.ts proves
TS-faithfulness and isFunction-delegation via a stub visitor.
The bench parameterization (measure.mjs) is sequenced into U7, where the
first C-family scaling scenario makes the {grammar, visitorFactory} seam
validatable against a real non-TS language.

* feat(cfg): C and C++ CFG visitor + def/use harvest (#2195 U2)
Add createCCfgVisitor/createCppCfgVisitor over a shared CCfgWalk core.
Grammar introspection confirmed tree-sitter-c and tree-sitter-cpp share
every control-flow node type/field, so CppCfgWalk extends CCfgWalk with
only the C++-only nodes (try/catch/throw/for_range_loop/lambda) via a
visitExtra hook -- no language conditionals (AGENTS no-language-naming).
Wire both into c-cpp.ts providers.
Harvest (c-cpp-harvest.ts): two-phase binding table + per-statement
defs/uses/mayDefs (no sites[] yet -- U6). Edge kinds match the TS
contract; functionStartColumn populated; non-terminating loops (for(;;),
while(1)) emit the structural exit-escape edge so EXIT stays
reverse-reachable and CDG is not silently skipped -- verified against the
production post-dominator + control-dependence solvers (for(;;) -> 3 CDG
edges). buildFunctionCfg returns undefined rather than throwing.
23 real-parser regression tests; grammar-literal gate green (literals
validated against both grammars). Documented gaps: C++ RAII destructors,
setjmp/longjmp, computed goto (route to EXIT + warn).

* feat(cfg): C# CFG visitor + def/use harvest (#2195 U3)
Add createCsharpCfgVisitor + csharp-harvest over the shared CfgBuilder /
ControlFlowContext, modeling the C# statement taxonomy: if/else,
for/foreach/while/do, switch_section (+ switch_expression arms),
try/catch/catch_filter/finally, using + lock (deterministic finalizers --
dispose/release runs on normal AND exception exit, finally-* completion
edges on crossing jumps), goto/labeled, yield (surface only), return/
throw/break/continue. Wire into csharpProvider.
Every literal validated against tree-sitter-c-sharp via the introspection
probe (record_declaration, no else_clause, switch_section, positional
access where no field exists). Edge kinds match the contract;
functionStartColumn populated; while(true) keeps EXIT reverse-reachable
(production CDG probe: 3 edges). buildFunctionCfg returns undefined
rather than throwing.
34 real-parser regression tests; grammar-literal gate green; no
regression (cfg unit dir 256/256, tsc clean). Documented gaps: yield
iterator state machine, goto case/default, async suspension points.

* feat(cfg): Java CFG visitor + def/use harvest (#2195 U4)
Add createJavaCfgVisitor + java-harvest over the shared CfgBuilder /
ControlFlowContext: if/else, classic for, enhanced-for, while, do-while,
classic-vs-arrow switch (switch_block_statement_group fallthrough vs
switch_rule no-fallthrough), try/catch/finally + try-with-resources
(auto-close synthesized as a finalizer, closes on normal AND exception
exit) + synchronized (monitor-release finalizer), labeled break/continue
to the labeled frame, yield, return/throw/break/continue. Wire into
javaProvider.
Every literal validated against tree-sitter-java via the probe
(switch_expression covers both switch forms, generic_type, line_comment,
for init field). Edge kinds match the contract; functionStartColumn
populated; while(true)/for(;;) keep EXIT reverse-reachable (production
CDG probe: 3 edges; hazard fixture: 34 CDG edges). buildFunctionCfg
returns undefined rather than throwing.
43 real-parser regression tests; grammar-literal gate green; no
regression (cfg unit suite 304, tsc clean). Documented gaps: switch-as-
expression-value inline, yield state machine, async/field-write defs.

* feat(cfg): Go CFG visitor + def/use harvest (#2195 U5)
Add createGoCfgVisitor + go-harvest, the highest-divergence target:
for_statement (all four shapes -- for_clause C-style, while-style,
range_clause, bare for{}), expression/type switch (no implicit
fallthrough) + explicit fallthrough_statement, select_statement, defer
(LIFO finalizer legs at function exit), go (call is straight-line; the
closure body is its own CFG via isFunction), labeled break/continue/goto,
multiple-return assigns (a, b := f() defines each LHS). Wire into
goProvider.
CRITICAL (review A2): every non-terminating shape -- for{}, for cond{},
select{} with no default -- emits a structural exit-escape edge so EXIT
stays reverse-reachable and the production CDG is not silently skipped.
Verified: for{} -> CDG=3, select{} -> CDG=1, for-range -> CDG=2, all
exitReachable=true.
Every literal validated against tree-sitter-go via the probe. 32
real-parser regression tests; grammar-literal gate green; no regression
(186 across all 5 visitors + gate, full cfg unit 331, tsc clean).
Documented gaps: panic/recover unwind, goroutine happens-before.

* feat(cfg): call-site sites[] taint substrate for C-family (#2195 U6)
Extend the C/C++/C#/Java/Go harvests with the call-site sites[] taint
substrate (SiteRecord/SiteArgOccurrence), mirroring the TS shape so the
shared taint matcher consumes all languages uniformly. Extract the
grammar-agnostic site machinery into cfg/visitors/call-site-harvest.ts
(CallSiteFactAccumulator -- names no language); each harvest adds only its
per-grammar visitCall/walkChain over its call node (C/C++ call_expression,
C# invocation_expression, Java method_invocation, Go call_expression).
INERT BY DESIGN: no C-family taint model exists (registerBuiltinTaintModels
is TS/JS only), so getSourceSinkConfig returns undefined for these
languages and the harvested sites produce ZERO TAINTED edges -- the
positive source->sink->TAINTED path is deferred with the model authoring.
sites emitted only when non-empty; facts-only attachment, block/edge
topology unchanged (pre-existing topology + def/use tests byte-identical).
23 new substrate tests; 574 green across the cfg/taint/emit suites; gate
green; tsc clean.

* test(cfg): worker-mode PDG integration + bench parameterization (#2195 U7)
Prove the five C-family visitors build PDG through the REAL worker
pipeline. pipeline-pdg.test.ts: per-language (C/C++/C#/Java/Go) temp repo
run with pdg:true asserts BasicBlock+CFG+REACHING_DEF+CDG all > 0 (CDG>0
proves EXIT stays reverse-reachable end-to-end through the worker, incl.
each fixture's non-terminating loop/select); a paired run with pdg off
asserts == 0, the two flag-off graphs byte-identical (R3), no PDG types
leak, pinned by a golden snapshot. Counts e.g. Go 151 BB / 56 CDG.
Parameterize bench/cfg/measure.mjs by a per-language LANGS registry
resolved generically via getLanguageGrammar + getProvider(X).cfgVisitor
(no static import table). Default TS byte-identical -- all 6 TS
fingerprints unchanged under --check; taint-dense stays TS-only
(TS_JS_TAINT_MODEL never runs against model-less C-family CFGs). Add a
go:branchy scenario+baseline (namespaced) -- its fingerprint shape
(32 blocks/46 edges) matches TS branchy, cross-validating the Go visitor.
15 pipeline tests + bench --check PASS (7 scenarios); 354 unit cfg green;
dist rebuilt clean. Absorbs the bench parameterization deferred from U1.

* feat(cfg): Python CFG visitor + def/use harvest (#2195 U8)
Add createPythonCfgVisitor + python-harvest -- the most structurally
divergent target (indentation blocks, elif, for/while-else, with, try/
except/except-group/else/finally, match/case, comprehensions, walrus),
confirming the shared CfgBuilder/ControlFlowContext core carries no
brace-family assumptions. for/while else-clause sits on the normal-
completion edge (not break); with modeled as try/finally dispose; match
has no fallthrough. Wire into pythonProvider.
Every literal validated against tree-sitter-python via the probe.
while True: keeps EXIT reverse-reachable (production CDG probe: 3 edges;
fixture: 42 CDG edges). 37 real-parser tests; gate green; no regression
(cfg unit 391, tsc clean). Gaps: async/generator suspension, comprehension
scope over-approximation. No sites[] (taint substrate, separate).

* feat(cfg): PHP CFG visitor + def/use harvest (#2195 U9)
Add createPhpCfgVisitor + php-harvest: if/elseif/else (+ alt colon
syntax), for/foreach/while/do-while, switch (fallthrough) + match (no
fallthrough), try/catch/finally, break N/continue N (N-th enclosing
loop), goto, return/throw. Wire into phpProvider.
Every literal validated against tree-sitter-php (php_only) via the probe
(for_statement initialize/condition/update; throw_expression not
throw_statement; break/continue integer child). while(true) keeps EXIT
reverse-reachable (production CDG probe: 3 edges; break 2 escapes the
outer loop). 35 real-parser tests.
Also repoint worker-roundtrip's "non-CFG language" gate test from Python
(which now has a cfgVisitor) to COBOL (the permanent non-goal of the
rollout) -- a stale assertion the Python commit invalidated. Full
in-process sweep green (452 across 18 files). Gaps: match inline value,
goto plain-block.

* feat(cfg): Ruby CFG visitor + def/use harvest (#2195 U10)
Add createRubyCfgVisitor + ruby-harvest: if/unless/elsif/else +
statement-modifier forms (x if c, x while c), while/until/for (until
inverts the sense), case/when + case/in (pattern, no fallthrough),
begin/rescue/else/ensure (ensure=finally, rescue=catch) + retry
(loop-back into begin), return/break/next/redo, blocks/lambdas as their
own closure CFGs. Wire into rubyProvider.
Every literal validated against tree-sitter-ruby via the probe (case vs
case_match, modifier nodes, typed rescue/ensure children). loop do /
while true keep EXIT reverse-reachable (production CDG probe: 3 edges).
34 real-parser tests; comprehensive sweep green (486). Gaps: yield,
expression-position if/case/begin inline, ivar/gvar non-local defs.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat(cfg): Rust CFG visitor + def/use harvest (#2195 U11)
Add createRustCfgVisitor + rust-harvest for the expression-oriented Rust:
if/else + if-let, loop (infinite -- structural escape edge), while/
while-let/for, match (no fallthrough) + guards, labeled break/continue
('outer), break-with-value, ? operator (try_expression) as an
early-return throw edge to EXIT, let-else (diverging else). visitLet
handles control-flow in value position (let x = loop/if/match). Wire into
rustProvider.
Every literal validated against tree-sitter-rust via the probe (label is
a named child not a field; line_comment; _ pattern). loop {} keeps EXIT
reverse-reachable (production CDG probe: 3 edges). 33 real-parser tests;
comprehensive sweep green (519). Gaps: panic, async/.await, macro bodies.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat(cfg): Swift CFG visitor + def/use harvest (#2195 U12)
Add createSwiftCfgVisitor + swift-harvest (vendored tree-sitter-swift via
requireVendoredGrammar): if/else + optional binding (if let), guard...else
(diverging early exit), for-in/while/repeat-while (bottom-test), switch
(no implicit fallthrough; explicit fallthrough keyword; where guards),
do/catch + try/try?/try!, defer (LIFO finalizer at scope exit), labeled
break/continue, control_transfer_statement (one node for break/continue/
return/throw). Wire into swiftProvider.
Every literal validated against the vendored grammar via the probe (no
block node; if-let folds into condition+bound_identifier; defer parses as
a call_expression with trailing closure). while true keeps EXIT
reverse-reachable (production CDG probe: 3 edges). 24 real-parser tests;
comprehensive sweep green (543). Gaps: computed properties, defer
block-scope approx, fatalError traps.

* feat(cfg): Kotlin CFG visitor + def/use harvest (#2195 U13)
Add createKotlinCfgVisitor + kotlin-harvest (vendored tree-sitter-kotlin):
if/else, when (subject + subjectless, no fallthrough), for/while/do-while,
try/catch/finally, jump_expression (return/return@/break/break@/continue/
continue@/throw), labeled loops, control_structure_body unwrapping,
expression-body functions. The grammar is field-less for control flow, so
the visitor navigates by child type+position. Wire into kotlinProvider.
Every literal validated against the vendored grammar via the probe
(line_comment/multiline_comment, not comment). while (true) keeps EXIT
reverse-reachable (production CDG probe: 3 edges; worker-mode fixture:
BB=82, CDG=41). 28 real-parser tests; comprehensive sweep green (571).
Gaps: value-position if/when/try inline, inline-fun non-local return,
getters/setters.

* feat(cfg): Dart CFG visitor + def/use harvest (#2195 U14)
Add createDartCfgVisitor + dart-harvest (vendored tree-sitter-dart):
if/else, C-for/for-in/while/do-while, switch (empty-case fallthrough +
explicit continue-label) + switch_expression, try/on/catch/finally +
rethrow + assert (throw edges), return/break/continue/throw, labeled
loops, arrow bodies, closures. Dart splits a function into sibling
signature + function_body nodes, so the body (or function_expression) is
the CFG-bearing node. Wire into dartProvider.
Every literal validated against the vendored grammar via the probe (only
constant_pattern exists; removed speculative relational/logical pattern
names). while (true) keeps EXIT reverse-reachable (production CDG probe:
3 edges). 34 real-parser tests; comprehensive sweep green (605). Gaps:
labeled-loop grammar quirk (read via ERROR sibling), async straight-line,
value-position if/switch inline.

* feat(cfg): Vue (reuse TS visitor) + worker-mode proof for all langs (#2195 U15)
Vue SFC <script> blocks are extracted and parsed with the TS grammar
(parse-worker languageMap[Vue] = TypeScript.typescript), so wire
vueProvider.cfgVisitor = createTypeScriptCfgVisitor() -- pure reuse, no
Vue-specific visitor. vue-visitor.test.ts replicates the worker path
(extractVueScript -> TS parse -> CFG) and confirms branch edges + EXIT
reverse-reachable + CDG>0.
Extend pipeline-pdg.test.ts with a worker-mode block covering all eight
remaining languages (Python/PHP/Ruby/Rust/Swift/Kotlin/Dart/Vue): per-
language temp repo, real worker pool, BasicBlock+CFG+REACHING_DEF+CDG all
> 0 with --pdg (CDG>0 proves EXIT reverse-reachable end-to-end through the
worker despite each fixture's non-terminating loop), == 0 without. Counts
e.g. Ruby 122 BB/45 CDG, Vue 49 BB/11 CDG. 30 pipeline tests green.
COBOL: documented as the deliberate PDG non-goal (no grammar, exotic
PERFORM/GO-TO control flow) in cobol.ts + the worker-roundtrip gate.
This completes PDG language coverage: every supported language except
COBOL now builds CFG/REACHING_DEF/CDG under --pdg.

* fix(cfg): surface skippedUnsoundFunctions in per-language stats (#2195 U2)
emitFileCdg computes skippedUnsoundFunctions (functions whose CDG is
withheld because EXIT isn't reverse-reachable from all blocks) but run.ts
dropped it on the floor — only cdgEdges/cdgDropped were aggregated. Add
the aggregation + a stats-line segment so CDG coverage gaps are an
explicit signal, not silent. Establishes the baseline skip count that
makes the U1 synthetic-escape pass's effect (the drop to genuine
anomalies only) measurable.
Additive; no emit-logic change. The emit-side field is covered by
cfg-emit.test.ts (asserts skippedUnsoundFunctions===1 + the warn on a
disconnected-block CFG); the run.ts aggregation is a thin pass-through.

* fix(cfg): synthetic-escape pass restores CDG for exit-unreachable cycles (#2195 U1)
Unconditional goto-cycles (C/C++/C#/Go) wire a backward seq edge with no
structural exit-escape edge, so EXIT becomes non-reverse-reachable and
emitFileCdg silently skipped ALL control-dependence for the function.
New cfg/synthetic-escape.ts: a pure deterministic SCC routine (iterative
Tarjan, sorted adjacency) + augmentForPostDom(cfg). No-op when EXIT is
already reverse-reachable (terminating fns + visitor-escaped loops are
byte-identical — returns the same object). Otherwise it batch-bridges
every exit-less SCC by adding an ANALYSIS-ONLY escape edge from the SCC's
controlling block (highest out-degree branch; lowest-index tie-break) to
EXIT, on a shallow-cloned FunctionCfg — never mutating persisted
cfg.edges. emitFileCdg threads that augmented view through BOTH
isExitReachableFromAllBlocks AND computeControlDependence (the Ferrante
walk re-reads cfg.edges, so a tree-only augmentation would be wrong).
Precision (anti-masking): only a trapped region containing a control
point (>=2-successor block) is bridged — a branch-less trapped region
carries no recoverable control-dependence and is indistinguishable from a
genuine construction anomaly, so it stays on the skip path (the existing
disconnected-block skip test still skips, skippedUnsoundFunctions===1). A
residual non-cycle dangling block is never bridged.
repro `void handler(int a){ start: if(a>0){work();} goto start; }`:
before exitReachable=false/CDG=0 → after one synthetic 2->1 edge,
exitReachable=true, exact CDG = {2->2:T,2->2:F,2->3:T,2->4:T,2->4:F}
(pinned exactly, not CDG>0 — catches a wrong representative). AC2 property
test extended to the augmented graph; per-language goto-cycle regressions
(C/C++/C#/Go). 199 cfg tests green; bench --check fingerprints unchanged
(analysis-only, zero persisted drift).

* test(cfg): isolate the non-terminating-loop hazard in worker CDG asserts (#2195 U3)
The pipeline-pdg worker-mode blocks asserted a whole-fixture cdg>0
aggregate (satisfied by any branching fn) while the comment claimed it
proved the non-terminating-loop EXIT-reachability end-to-end. Add a per-
language `hazard` marker + isolate the assertion: locate the hazard
function's BasicBlocks by its anchor and assert >=1 CDG edge is sourced
within it (a marker mutation now fails the test — non-vacuous). C# keeps
the aggregate (its fixture has no infinite loop). Comments corrected.
Switch the 7 visitor unit tests (java/csharp/dart/kotlin/php/swift/c-cpp)
from the local exitReachableFromAll CFG-shape helper to the production
isExitReachableFromAllBlocks + computeControlDependence on the hazard
function, matching go/python/ruby/rust/vue. 241 unit + 30 pipeline green.

* test(cfg): gate vendored-grammar worker assertions on isLanguageAvailable (#2195 U4)
The Swift/Kotlin/Dart worker-mode pipeline-pdg cases require a vendored
grammar prebuild that may be absent on a CI platform — they'd go red
there. Mark those three REMAINING_LANGS entries `vendored` and gate both
the --pdg-on and --pdg-off `it`s on isLanguageAvailable(SupportedLanguages
[lang]) → it.skip when the grammar can't load. Installed-grammar
languages stay unconditional. Grammars present here, so all 30 run green.

* refactor(cfg): remove dead useCount() from swift + rust harvests (#2195 U5)
useCount() was declared on the local FactAccumulator in swift-harvest.ts
and rust-harvest.ts but never called (a copy-paste artifact; ruby's copy
IS used in an emit guard, so it stays). Pure deletion — the swift/rust
visitor suites stay green.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* refactor(cfg): standardize harvester API table()->bindingTable() (#2195 U9)
The binding-table accessor was named table() in the C/C++/C#/Go harvests
but bindingTable() in the other 7. Rename the 4 (definitions + their
visitor call sites) to the majority name bindingTable(). Pure rename; the
4 visitor suites stay green and tsc confirms no call site was missed.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* refactor(cfg): consolidate scope-tree substrate into ScopeTreeHarvester (#2195 U6)
The Go/Java/C#/C-C++ def/use harvesters each carried a byte-identical copy
of the lexical scope-tree machinery (Scope record, two-phase resolution
cache, openScope/nearestScopeOf/resolve/def/use/conditional/bindingTable,
~270 lines total). Extract it into an abstract ScopeTreeHarvester base; the
four harvesters now extend it and supply only their genuine per-language
variation (the prescan switch, plus Go's _-blank-identifier overrides of
declare/def/use). Net -422 lines. Mechanical and byte-equivalent: cfg unit
suite 613 passed, bench --check fingerprints unchanged.

* refactor(cfg): consolidate no-site def/use accumulator into DefUseAccumulator (#2195 U7)
The Kotlin/Python/Ruby/Rust/Dart/Swift harvesters each carried a
byte-identical copy of the no-site def/use accumulator (~270 lines total;
only Ruby's adds the live useCount() emit-guard helper). Extract it as an
exported DefUseAccumulator beside CallSiteFactAccumulator in
call-site-harvest.ts (the PR's own model for the with-site superset); the six
harvesters import it under their existing local FactAccumulator name. Pure
byte-equivalent move, no logic change: cfg unit suite 613 passed, tsc clean,
bench --check fingerprints unchanged (TS/Go paths untouched).

* test(cfg): consolidate copied visitor-test helpers into cfg-harness (#2195 U8)
The 13 *-visitor.test.ts files each copied a byte-identical set of CFG-shape
helpers (edgeKinds/block/reaches/reachable/bindingIdx/allSites/hasAnySites,
~380 lines total). Export them once from test/helpers/cfg-harness.ts and import
per file (only the subset each references). Also drop each file's local
exitReachableFromAll — a re-implementation of the production
isExitReachableFromAllBlocks (semantically identical: false iff some
entry-reachable non-EXIT block can't reach EXIT) — and point its live call
sites at the already-imported production function. Pure test-only mechanical
move, behavior-preserving: tsc clean, test/unit/cfg/ 613 passed unchanged.

* test(cfg): pin *-harvest.ts literals to their own grammar in the gate (#2195 U10)
The grammar-literal validation gate scans cfg/visitors/, but a <lang>-harvest.ts
basename was not in BASENAME_LANGS, so fileLanguages() fell it through to the
weak ALL_LANGS valid-if-any bucket — a node-type literal dead in its own grammar
but valid in some other grammar would pass undetected. Strip the -harvest suffix
and reuse the visitor basename map so go-harvest -> Go, c-cpp-harvest -> C+C++,
typescript-harvest -> TS, etc. The two language-agnostic harvesters
(call-site-harvest, scope-tree-harvest) name no grammar and stay valid-if-any.
Also corrects the now-inaccurate mode2Files comment. Adds a fileLanguages unit
test; the existing gate stays green (no harvest file has a dead literal), and a
scratch probe confirmed a bogus go-harvest literal is now caught.

* feat(cfg): defensive per-statement cap on harvested taint sites (#2195 U11)
A statement's harvested sites[] had no explicit bound — a pathological or
machine-generated statement (hundreds of nested calls) could grow it without
limit. Add DEFAULT_PDG_MAX_SITES_PER_STATEMENT (512, mirroring the PDG edge/fact
cap style): openCallSite/addMemberRead check-before-push and stop at the cap,
keeping the first 512 sites fully intact and setting an observable
sitesTruncated flag. A cap-dropped openCallSite returns a -1 sentinel that
pushFrame/setSite*/the occurrence fan-out all tolerate (no dangling parent/via,
no clobber of kept sites). Generous enough that no real statement is affected:
bench --check fingerprints unchanged, cfg unit suite 617 passed.

* ci(codeql): exclude nested test fixtures from the CodeQL gate (#2195)
The CodeQL results gate failed on test/integration/cfg/fixtures/python-hazards.py
('total' may be used before init, unused vars) — but that file is an intentional
CFG/PDG hazard fixture, exactly the synthetic broken-code the existing
'**/test/fixtures/**' exclusion is meant to skip. That glob does not match the
deeper test/integration/cfg/fixtures/ path, so the hazard fixtures leaked into
the scan. Add '**/test/**/fixtures/**' to cover fixtures nested anywhere under a
test tree. Analyze (python) and Analyze (javascript-typescript) both already pass
— production code is clean; this only silences fixture noise.

* style(cfg): apply prettier + drop unused imports across the PDG files (#2195)
The merge of main into this branch pulled in the stricter quality gates
(prettier --check . and eslint .), which surfaced pre-existing formatting in the
PDG/CFG rollout (line-width wrapping across the visitor + harvest files, bench,
tests) plus 9 no-unused-imports errors. Mechanical autofix only — npm run
format + lint:fix equivalent, scoped to gitnexus/: removes unused FunctionCfg/
SiteRecord type imports left by the U8 helper consolidation and stale
FinalizerFrame imports in python.ts/ruby.ts. No behavior change: tsc clean, cfg
unit suite 617 passed, eslint 0 errors. (gitnexus-web class-order noise is a
local tailwind-plugin artifact CI does not flag — left untouched.)

* fix(cfg): harvest C++ structured-binding defs (auto [a,b]=e) (#2195)
The C++ def/use harvester only recorded a def when an init_declarator's
declarator was a plain identifier, so a structured binding (auto [a,b] = mk(),
incl. the auto& reference form whose binding sits under a reference_declarator)
declared only the first name in phase 1 and emitted ZERO defs in phase 2 — a,b
were walked as spurious uses and later use(a)/use(b) resolved to a synthetic
module binding, silently corrupting REACHING_DEF/taint for an idiomatic C++17
shape. Unwrap the structured_binding_declarator in both phases and def every
identifier leaf; result-of-initializer flows to the whole list. Inert for C
(no structured bindings). Characterization tests added (plain + reference form).

* fix(cfg): model C++ co_return as a return terminator to EXIT (#2195)
co_return_statement was neither in CPP_CONTROL_FLOW_TYPES nor dispatched, so a
coroutine's co_return coalesced into a straight-line block and emitted a
spurious seq fallthrough to the following statement instead of an edge to EXIT
— statements after co_return looked reachable and the terminator edge was
missing, corrupting CFG/CDG for coroutines. Add the node type to the C++
control-flow set and dispatch it through visitReturn (block -> EXIT 'return',
no fallthrough). C path untouched; co_await/co_yield remain plain expressions.
Characterization test added; c-cpp suite + grammar-literal gate green, bench
--check unchanged.

* fix(cfg): harvest C# out-var and deconstruction-declaration defs (#2195)
Two idiomatic C# write shapes recorded ZERO defs, silently breaking
REACHING_DEF/taint:
- out-var (G(out var n) / G(out int n)) parses as a declaration_expression;
it was neither declared (phase 1) nor def'd (phase 2), so n resolved to a
synthetic module binding and the callee-written value had no reaching def.
- deconstruction declaration (var (a, b) = T()) has a variable_declarator whose
name slot is a tuple_pattern (null name field), so declareVariableDeclaration
+ the variable_declaration walk skipped it entirely (only the assignment form
(a,b)=T() was handled). Both a and b were dropped.
Declare + def the declaration_expression's identifier (must-def: out params are
definitely-assigned), and route a null-name variable_declarator through the
tuple_pattern via the existing declareForeachTarget/defTupleTargets helpers.
Characterization tests added; csharp suite 42 passed, grammar gate + bench
--check green.

* fix(cfg): put embedded-script CFGs in file coordinates via lineOffset (#2195)
A Vue SFC <script> block parses at row 0 but lives at lineOffset in the .vue
file. Every other worker-emitted graph node adds lineOffset to reach file
coordinates, but collectFunctionCfgs built FunctionCfgs from the extracted
script's raw rows and never offset them. Two consequences for .vue files:
- inter-procedural taint silently resolved NOTHING — the summary-harvest join
keys graph Function/Method nodes by their (offset) startLine but looked up the
CFG's (unoffset) functionStartLine, missing by exactly lineOffset, so no
FunctionSummary was ever produced;
- persisted BasicBlock startLine/endLine (and the id's functionStartLine
segment) pointed at the wrong .vue line, breaking source mapping.
Thread lineOffset into collectFunctionCfgs and shift every CFG source-line field
(functionStartLine/End, block start/end, statement + non-synthetic binding
lines) into file coordinates at the one production chokepoint. A 0 offset
returns the CFG unchanged, so .ts/.js/etc. stay byte-identical (bench --check
fingerprints unchanged; worker-roundtrip + pipeline-pdg green). Unit tests for
the shift + the 0-offset no-op added.

* feat(cfg): surface CDG soundness skips at warn, not just debug (#2195)
skippedUnsoundFunctions (a function whose EXIT is not reverse-reachable from
all blocks, so control dependence is withheld) was only reported inside the
per-language logger.debug stats line — while the taint/RD coverage-gap and
cap-drop counts surface unconditionally at warn. A language that systematically
trapped EXIT (an unmodeled non-terminating / multi-terminal shape the
synthetic-escape pass can't bridge) would silently lose all CDG. Add a parallel
unconditional warn (R8) alongside the R4 taint-gap warn. Observability only —
no graph change; emit-layer skip counting stays covered by cfg-emit's
skippedUnsoundFunctions test.

* fix(cfg): harvest Kotlin x++/--x as a def (#2195)
The Kotlin harvester had no postfix_expression/prefix_expression case, so an
increment/decrement fell to the default descent and recorded its operand as a
use only — never a def. Every sibling harvester (Java/C#/C++/Dart/TS/PHP) models
inc/dec, so a Kotlin counting loop (while/for using i++) silently dropped the
loop-carried reaching-def of the counter. Add the case: def AND use the operand
when it is a plain simple_identifier and the operator is ++/-- (other pre/postfix
forms — -x, !x, x!!, x? — stay pure reads, byte-identical to the old descent).
Characterization tests for postfix + prefix added; kotlin suite 30 passed,
grammar gate + bench --check green.

* fix(cfg): harvest Go select channel-receive binding as a def (#2195)
walkValue had no receive_statement case, so a select receive (case v := <-ch:)
fell to the default descent: v was recorded as a USE of an uninitialized var
and the channel-sourced definition was invisible to REACHING_DEF/taint —
channels are a primary taint source in Go. Add the case mirroring
short_var_declaration: def each left identifier, use the <-ch right, attach
resultDefs for the := short form. prescan already declared the binding; this
completes the phase-2 fact. go:branchy bench fingerprint unchanged; go suite
40 passed, grammar gate green.

* fix(cfg): harvest all names of a Dart multi-variable declaration (#2195)
`var a = 1, b = 2;` is one initialized_variable_definition whose first binding
is the name/value field pair and whose subsequent bindings are trailing
initialized_identifier children. Both prescan (declareInitializedVar) and the
walkValue case read only the name/value fields, so every name after the first
was never declared or def'd — `b` resolved to a synthetic module binding and
its REACHING_DEF/taint flow was lost. Iterate the trailing initialized_identifier
nodes in both phases. (Dart-3 record/list pattern declarations `var (a,b)=pair`
remain a separate follow-up.) dart suite 35 passed, tsc + grammar gate green.

* fix(cfg): bind Swift switch-case value patterns (case let n) (#2195)
A switch value-binding (case let n where …, case .some(let v)) was never
declared in prescan, so n/v resolved to a synthetic module binding and a body
use(n) did not link to any def — a very common Swift idiom silently lost its
data dependence. Declare the switch_pattern's bindings (prescan, reusing
declarePattern) and emit them as MAY-defs on the dispatch block (a case may not
match) via a new switchPatternFacts, propagated into the case body. swift suite
25 passed, tsc + grammar gate green. (The rare ?? / ternary-arm may-def — Swift
assignment-as-expression — remains a separate follow-up.)

* fix(cfg): wire Swift multi-catch throw edges to every handler (#2195)
visitDo routed the protected body's throw edge only to handlerEntries[0], so a
do { try r() } catch A {} catch {} left the 2nd..Nth catch handlers UNREACHABLE
from ENTRY — orphaned blocks whose error bindings + def/use facts were stranded
in a dead component (a soundness gap for idiomatic Swift typed multi-catch).
Swift tries the catch clauses in order and the thrown type is unknown at CFG
time, so every protected block may reach ANY clause: edge each protected block
to every handlerEntry. Found by the per-language CFG/CDG verification swarm
(reproduced: 2-catch=1, 3-catch=3 unreachable blocks). swift suite 26 passed,
tsc clean.

* fix(cfg): synthesize a protected block for an empty Kotlin try {} (#2195)
An empty `try {}` body produced zero protected blocks, so visitTry's throw-edge
loop wired nothing to the catch and the try's entry fell through to the finally
— leaving the catch handler block + its error binding orphaned (unreachable from
ENTRY), a malformed CFG with stranded def/use facts. Mirror the existing
empty-`catch` synthesis: when the try body is empty and there is a catch or
finally, synthesize one protected block so the catch handler(s) are wired and
the try entry is the body, not the finally. Found by the per-language CFG
verification swarm. Non-empty try is byte-identical; kotlin suite 31 passed,
tsc clean.

* perf(cfg): bound the reaching-defs fixpoint with a per-block visit ceiling (#2195)
The per-language verification swarm reproduced, AT PRODUCTION DEFAULTS, a
reaching-defs blow-up: a machine-generated ~2000-line all-loops function (under
DEFAULT_PDG_MAX_FUNCTION_LINES) reaches ~10k basic blocks because loops emit ~5
blocks/line, and the dataflow fixpoint is O(blocks^2.3) on deep loop nests —
measured 62s (C/C++) and 2.05s + 810MB (Go) for ONE function. maxFacts does not
help: the fact count stays LINEAR, so it never fires.
Iterative reaching-defs on a reducible CFG converges in O(loop-nesting-depth)
passes, so a worklist re-visits each block a small multiple of times for real
code. Add a maxBlockVisits ceiling (emit passes blocks.length × 64 — far beyond
any hand-written nesting depth, ~15) that bails when the fixpoint has not
converged. An unconverged fixpoint's in/out sets are not sound, so it returns
NO facts (status 'truncated', like the existing 'overflow' guard) — a per-
function coverage gap, never wrong facts. Real code is byte-identical: full cfg
suites 725 passed, bench --check fingerprints unchanged.
NOTE: computeControlDependence's O(N²) up-walk on deep post-dom chains is the
sibling concern but stays ~13ms in production (bounded by the line cap + the
CDG materialization cap); a CDG work-budget is a documented follow-up.

* fix(cfg): raise the parse-worker stack limit for deep CFG recursion (#2195)
The CFG visitors build per-function control-flow graphs by recursive descent
over the tree-sitter AST, so deeply-nested source overflows the worker thread's
call stack (~1.5k nesting levels) — caught per-function (R4 try/catch) but the
function silently gets no PDG. A worker thread's stack is governed by
resourceLimits.stackSizeMb (Node default 4 MB); the main process's
--stack-size=4096 flag does NOT propagate to worker threads (confirmed by prior-
art research on Node worker_threads). Raise it to 16 MB, pushing the overflow
threshold to several-thousand nesting levels — far beyond any hand-written code,
so only machine-generated/obfuscated nesting can still hit it (and that stays a
caught per-function skip, never a crash). Complements a future proactive depth
guard. pipeline-pdg worker tests 30 passed, tsc clean.

* perf(cfg): compute control dependence as a reverse-CFG dominance frontier (#2195)
The Ferrante §3.1.1 up-walk re-climbed the ipdom chain once per CFG edge,
which is Θ(N²) on a deep post-dom chain (a single branch fanning into a
shared spine took ~7.1s at 16k blocks). Replace it with the reverse-CFG
post-dominance-frontier formulation (Cytron, Ferrante, Rosen, Wegman &
Zadeck 1991): control dependence IS the dominance frontier of the reverse
CFG, computed bottom-up over the post-dom tree (PDF_local from a node's CFG
in-edges + PDF_up from its post-dom-tree children) in O(N + E + output).
LLVM (ReverseIDFCalculator), Joern (CdgPass) and WALA use the same form.
Output is the IDENTICAL deduped/sorted (controller, dependent, label) set:
verified byte-identical across all cfg unit+integration suites, the
cdg-snapshot oracle, and bench --check fingerprints (unchanged). The PDF
unions a label SET per (controller, dependent) pair, preserving the
multi-label rows the old per-row dedup kept on opposite-sense (goto-cycle)
arms. buildArmSenses, labelFor, the final sort and the maxEdges truncation
cap are kept verbatim; the post-order walk is iterative so a chain-deep
post-dom forest cannot overflow the stack.
Adds three regressions: multi-label-per-pair preservation, the literal
self-edge / NO_IPDOM seed guard (a !== x), and a fan-into-chain perf
tripwire (linear vs the former quadratic up-walk).

* docs(cfg): record the reaching-defs WTO no-go decision (#2195)
Weak-topological-order / loop-aware iteration (Bourdoncle 1993) was
evaluated as the fix for the O(blocks²) deep-loop-nest blow-up and
rejected: a faithful WTO solver was 104/104 byte-identical to the RPO
worklist but 0% faster — the cost is inherent dense-set propagation +
lattice merges, not visitation order, and the loop-body-skip shortcut is
unsound on irreducible (goto) CFGs. Document this at the RPO-order site
and the emit.ts revisit-ceiling constant so the shipped blocks×64 bound
reads as the sound backstop it is, with SSA-sparse reaching-defs named as
the deferred real fix. Comment-only; no behavior change.

* feat(cfg): proactive visitor nesting-depth guard + observable CFG skips (#2195)
The CFG visitors are recursive-descent with no shared base, so a
pathologically nested function (machine-generated / adversarial) could
overflow the worker's native stack — a nondeterministic RangeError that
escaped to the language-group catch and silently dropped EVERY remaining
file's CFG.
Guard it proactively: CfgBuilder tracks live recursive-descent nesting
depth via enterNesting/exitNesting, called at each visitor's visitBody and
visitSeq choke points (visitBody covers nested control constructs incl.
else-if ladders; visitSeq covers deeply-nested bare blocks). Exceeding
MAX_CFG_NESTING_DEPTH (500, far below the ~1.2k+ native limit and far above
real code's ≤~50) throws a typed, DETERMINISTIC CfgNestingDepthError instead
of waiting for the engine's nondeterministic overflow.
collectFunctionCfgs now isolates the build PER FUNCTION: the depth bail or
any other throw is caught, counted, and skipped — one bad function no longer
loses the whole file's CFGs. CollectedCfgs.skipped widens from a bare number
to reason-counted buckets (tooManyLines / tooDeeplyNested / buildError). The
worker stops discarding that count (parse-worker.ts), aggregates it
per-language onto ParseWorkerResult.cfgSkipped (survives the parse cache via
slim's `...result`), and mergeChunkResults merges + warns per-language so a
CFG coverage gap is observable, not silent.
Behavior-preserving on normal code: the guard never fires below 500 nesting,
so the cfg unit+integration suites (731), the CDG/RD/CFG snapshots and the
bench --check fingerprints are all byte-identical. The worker stackSizeMb
4→16MB bump shipped earlier (

fix(security): Harden CI permissions (#1454)
* Initial plan * chore(security): harden workflow permissions and pin Docker base image digests Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/2ddc8f2b-7355-48cf-9a0b-c06df66c3f47 * fix(security): restore permissions: {} on publish + release-candidate workflows These two release-publishing workflows had permissions: {} (the strictest valid form) before PR #1454, which replaced it with permissions: read-all. Every job in both files already declares its own permissions block, so the workflow-level default is only the safety net for future jobs added without one — read-all weakens that net for no benefit. Restore {} and the explanatory comment. Scorecard's TokenPermissions check accepts both forms, so this preserves U9 compliance. * fix(security): narrow permissions: read-all to contents: read on 13 workflows PR #1454 added permissions: read-all to 13 workflows that previously had no top-level permissions block. read-all is Scorecard-compliant but unnecessarily broad — every job in scope only needs contents:read at the workflow level (job-level blocks already grant the writes that any job actually performs). Snapshot of every job in the 13 workflows confirms contents:read is sufficient: - ci.yml: quality/tests/scope-parity have explicit contents:read job blocks; save-pr-meta uses upload-artifact only (no token scopes needed); ci-status is pure shell. - ci-e2e.yml, ci-quality.yml, ci-scope-parity.yml, ci-tests.yml: all jobs do checkout + npm + tsc/vitest/playwright/upload-artifact only; no API token scopes required. - claude.yml, codeql.yml, dependency-review.yml, docker.yml, gitleaks.yml, pr-labeler.yml, trivy.yml, workflow-lint.yml: all jobs already declare their own job-level blocks (security-events:write, pull-requests:write, packages:write, etc.) so the workflow-level default does not gate them. zizmor (--min-severity high) is clean on the resulting tree. Pre-existing medium findings (secrets-inherit, artipacked) are in unrelated workflows and untouched by this commit. scorecard.yml also uses read-all but pre-existed PR #1454 and is deferred to a follow-up PR per the plan's scope boundary. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: Gergő Magyar <gergomagyar@icloud.com> |

chore(quality): exclude test/fixtures from CodeQL, ESLint, and Prettier (#1313)
Test fixtures are intentionally synthetic inputs (broken/unused code, malformed samples) used to exercise the analyzer. Quality-tool findings on them are noise, not real bugs — they were drowning out actionable signal in the GitHub Security tab. - CodeQL: add `**/test/fixtures/**` to paths-ignore in codeql.yml - ESLint: add `gitnexus-web/test/fixtures/**` to global ignores (the gitnexus/ counterpart was already ignored) - Prettier: add `gitnexus-web/test/fixtures/` to .prettierignore (same gap as ESLint) Real test files (*.test.ts) remain in scope so genuine issues like js/file-system-race and js/insecure-temporary-file in test code still surface. |

Reporting. Documents in-CI scans landed in this branch and recommended
admin actions for forks.
Plan: docs/plans/2026-05-03-001-feat-automated-security-scans-plan.md (U7)
* fix(review): apply autofix feedback
- CodeQL paths-ignore: replace brace expansion (parser.{c,js}) with two
explicit entries — CodeQL uses .gitignore-style globs that do NOT support
brace expansion, so the original pattern matched no files.
- Trivy: pin aquasecurity/trivy-action from @master to @0.28.0 — mutable
refs are a supply-chain risk and are exactly what zizmor (added in this
same plan) is meant to flag.
ce-code-review run: /tmp/compound-engineering/ce-code-review/20260503-104259-279c3bc4/
* docs(review): record residual review findings
ce-code-review autofix run flagged three downstream-resolver items
that are not blockers but should land before promoting any of the new
security workflows to required PR checks.
Source: /tmp/compound-engineering/ce-code-review/20260503-104259-279c3bc4/
* fix(ci-security): address all zizmor + dependency-review violations
Resolves all GitHub Advanced Security findings on PR #1297:
- Add 'persist-credentials: false' to actions/checkout in 5 workflows
(codeql, dependency-review, gitleaks, trivy, workflow-lint). Prevents
the GITHUB_TOKEN from persisting in .git/config for downstream steps
to read. Scorecard already had it.
- Pin every net-new third-party Action to a commit SHA (was: major-tag
refs flagged by zizmor as 'unpinned action reference'):
github/codeql-action -> v3.35.3 (0daab03)
actions/dependency-review-action -> v4.9.0 (2031cfc)
gitleaks/gitleaks-action -> v2.3.9 (ff98106)
ossf/scorecard-action -> v2.4.3 (4eaacf0)
docker/build-push-action -> v6.19.2 (10e90e3)
- Bump aquasecurity/trivy-action 0.28.0 -> 0.36.0 (ed142fd). Versions
< 0.35.0 are flagged by GHSA-69fq-xp46-6x23 (briefly compromised
supply chain). Caught by Dependency Review on the introducing PR.
- Pin pipx-installed zizmor to 1.24.1 (was unpinned 'pipx install
zizmor' resolving to latest at run time).
Removes the now-stale residual-findings doc since every item it
recorded is resolved on this branch.
* fix(ci-security): clear remaining zizmor findings
After landing the new security workflows, zizmor reported 5 high+
findings against pre-existing workflows (none introduced by this PR's
new files, all introduced by zizmor's wider scope). Resolved per
research at docs.zizmor.sh and PyO3/maturin issue #2425:
Real fixes (cache-poisoning):
- publish.yml + release-candidate.yml: add 'package-manager-cache:
false' to actions/setup-node. setup-node v5+ enables caching by
default when a packageManager field is present in package.json;
explicit opt-out keeps release installs hermetic and clears the
audit. Cost: ~30s slower per release run.
Documented exemptions (dangerous-triggers, .github/zizmor.yml):
- ci-report.yml: workflow_run is REQUIRED to post sticky comments
on fork PRs (forks have read-only GITHUB_TOKEN on pull_request).
- claude.yml: pull_request_target is required by claude-code-action
to access secrets and post fork-PR review comments. PR checkouts
pin fork HEAD SHA to mitigate TOCTOU.
- pr-labeler.yml: pull_request_target on the autolabel job needs
pull-requests:write. release-drafter runs with dry-run:true and
reads config from the BASE ref only.
Each exemption carries the documented mitigation in zizmor.yml.
workflow-lint.yml now passes --config to both the SARIF and the
gate invocations.
Local 'zizmor --config .github/zizmor.yml --min-severity high .'
reports: No findings to report. Good job!
