* fix(javascript): bind defaulted and destructured Webpack factory roles
A Webpack factory whose module parameter was defaulted (`e = {}`) or
destructured (`{exports: x}`) reported an exact empty export list with
complete coverage, because roles were taken only from plain identifiers.
Bind factory roles once, by position, in javascriptBundlerFactoryRoles.
Defaulted module/exports parameters keep their role (the convention always
supplies the argument), `{exports: alias}` binds the alias to
module.exports, and a repeated sloppy parameter name binds its last
argument. Other role patterns (rest, array, nested or computed keys, a
non-identifier loader) receive no role and count as an unknown finding,
so the file's analysis is partial instead of claiming no exports. The
export collector, the factory require name and the standalone bootstrap
externals all use these parsed roles.

* fix(javascript): keep factory receivers through unordered reads
A defaulted role parameter kept the unused default in the binding facts
passed to write ordering, so a receiver read inside a loop, nested block
or closure was unresolved and its export silently dropped while the
module stayed complete.
The role owner now removes defaults the calling convention never runs
before ordering. Separately, an export-shaped write through a role
binding whose read stays unordered now counts as an unknown finding
instead of being dropped, so an incomplete list is never reported as
complete.

* fix(javascript): treat never-run factory parameter defaults as dead code
Removing unused defaults from binding facts let writes inside a default
expression reach the export collector: `(e = {}, t = (() => {
e.exports.ghost = 1; })())` reported `ghost` although Webpack supplies
both arguments. Loader calls in such defaults also produced require
references and async chunk keys.
The role owner now records the default of every role parameter, any
binding pattern included, as never run. The export collector, the
async-chunk walk and the static source traversal skip those subtrees,
so they yield no exports, references or chunk keys. Defaults of later,
non-role parameters still run and are still reported.

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.
The canonical `n.n` getter proof scanned for direct `loader.n =` assignments
and four Object methods on its own. `Reflect.set`, `Reflect.defineProperty`,
`delete`, destructuring and unknown-key writes left the proof intact, so a
replaced or deleted getter still attributed BrowserWindow calls to Electron.
Any Object method call on the loader also rejected the proof, even for an
unrelated key.
The proof now uses the shared identity-write owner
(`collectJavaScriptIdentityWritesSteps` with the module interop's intrinsic
resolution), as ambient writes already do. A write whose path may select `n`
(the key itself, an unknown key, or the whole loader) counts; exactly one
canonical assignment installed before entry dispatch remains required.

Track module writes and escapes at their owner, preserve capture and reassignment ordering, and share CommonJS/default namespace identity without erasing parent-slot changes. Carry write sites into ambient alias resolution and use parsed write targets across consumers. Deduplicate returned-reference work with cycle context; retain unchanged temporal selection identity so provenance memoization stays effective.
Reviewed fixes include #2041, #2465, #2830, #2881, and #2948. Remove superseded mutation representations and the ineffective per-markValue dedup layer.
Validation: 380 focused JavaScript tests passed under a 384 MiB heap cap, including the previously aborting 30-level/128-call alias regression. Six public CLI/MCP builtin tests passed. Exact pdf.js completed-workflow performance remains unmeasured.
