* fix(javascript)!: preserve operator influence in semantic traces
* test(javascript): align semantic influence regressions
* style(javascript): format semantic IR
* test(javascript): follow literal argument seed influence
* fix(javascript): keep one literal node per operator operand
Reuse an existing literal for operator influence, and treat TypeScript
assertion wrappers as transparent when deciding whether a call result is used.
* test(mcp): assert bundle path issues by field
compare_bundles reports each relative path as an invalid_format issue
instead of one joined diagnostic sentence.
* fix(javascript): index operator literals by range and initializer
Repeated string operands rescanned every retained literal and every
initializer flow. Lookup now uses those indexes, and a 1200-declaration
file still projects one literal per operand.
* fix(javascript): keep literal and call facts on their own occurrences
Operator literals match their own source range, so a nested function does
not inherit the enclosing declaration's literal. A direct argument still
reaches the call, while the assigned result follows modeled returns.
for-loop initializers and updates are discarded call results.
* test(javascript): expect conditional operand literals beside binding values
A conditional binding keeps one candidate literal per union value and one
operator literal per operand token. Those are different facts, so the
aggregate payload check counts four nodes and compares literal seeds in
query order.
* perf(javascript): index call return flows by call site
projectCalls filtered every call return for each assigned result. Group
those flows once while projecting returns-to-call edges.

Record erasure during definition indexing and reuse it across runtime references, captures, effects, module links, routes, Electron and Vite. Preserve source type links and emitted decorator and computed-key effects; keep actual runtime reads and escapes conservative.
Validation: 1,647 focused tests and 9 documentation tests passed, with build, static and documentation gates. The inherited reference-lifetimes stress file exhausts a 512 MiB worker on both unmodified 18451e479 and this change; that file remains unverified. TypeScript 7.0.2 emit was inspected for ES2022 and ES2018 without executing emitted code.
* feat(javascript): link assignment right-hand sides to their writes
A declaration carries its value forward, but a later assignment to a
variable, a property or through a compound operator stopped the forward
trace at the right-hand-side read. The semantic IR now records one
syntactic assignment flow per simple assignment target (ranges, operator,
owning callable), and the graph projection connects each retained read
of the right-hand side to the write occurrence through a defines
relation. Compound assignments also consume the previous value of the
target; the written value itself stays unknown, keeping the boundary of
#4342 intact.
Fixes#6193

Index unshadowed direct-eval sites once at the semantic owner. Distinguish
lexical rebinding, non-strict eval-introduced names, and possible mutation
of reachable objects. Reuse existing effect timing and capture proofs;
retain original definitions and module origins without inventing assignments
or parsing or executing eval payloads. Query object uncertainty conservatively
across the owning activation so aliases remain covered when names are shadowed
or leave block scope. Retain no binding-by-eval table.
Use the shared facts for values, read provenance, reference effects and child
argument shapes. Preserve indirect/optional/shadowed eval controls, unrelated
activations, immutable shapes, strict-mode bindings and prior primitive
captures. Remove obsolete reference plumbing and the source-wide eval blocker.
Validation: 306 focused checks across 16 files pass, including compiled CLI
and stdio MCP return projections, constructor uncertainty and child-process
consumers. Against the preceding SQLite commit, 9 of 23 selected checks fail
and 14 controls pass. Static/docs/test discovery (1559 files) pass. Two source
reviews found no remaining scoped blocker after alias and sloppy-name fixes.
No analyzed JavaScript, SQLite engine, heavy test or profiler was executed.
Conservative object reachability can intentionally lose exactness; large-case
opaque-query CPU and memory remain unmeasured.
Fixes#4875
After #1542 the longest event-loop blocks on large bundles were single AST
traversals inside one analyzer: member-mutation collection with its
fixpoint, static source analysis, and function fingerprints, each about
one second on Obsidian's 3.7 MB app.js.
- traverseJavaScriptAstSteps yields every 1,024 visited nodes with the
same visit order; traverseJavaScriptAst drains it, so every existing
caller is unchanged.
- Member mutations, static analysis and fingerprints run as steps. The
member-mutation fixpoint yields every 64 references, and fingerprints
yield between callables.
- The now-unused synchronous member-mutation and fingerprint wrappers are
removed.
Graph IDs and complete result digests match main on three inputs,
including obsidian.asar. Over two runs there, the longest block falls
from about 920 ms to 740 ms, the second from 860 to 595 ms, and blocks
over 250 ms from 27 to 18, with total time within 1.5%.

* fix(javascript): yield inside semantic analysis and large projection passes
After #1525 the longest event-loop blocks were single stages on very large
files: semantic analysis of Obsidian's 3.7 MB app.js ran 5.8 s in one piece,
and its object projection 1.8 s.
- analyzeParsedJavaScriptSemanticsSteps yields between the analysis phases
and between the eight derived collectors; the synchronous function drains
it, so results are unchanged.
- Per-file analysis yields between open-receiver classification and static
analysis and drives the semantic steps.
- Semantic node creation, definitions and references, and the object and
frontier passes yield every 64 items. Node creation keeps source order,
which the per-file node budget depends on.
On obsidian.asar the longest block falls from 5,355 ms to 907 ms with the
same total time (40.6 s to 39.5 s). Graph IDs and complete result digests
match main on five inputs. Remaining blocks up to about 0.9 s are single
AST traversal passes inside the analyzers.
