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 Remove superseded mutation representations and the ineffective per-markValue dedup layer.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.
* fix(javascript-semantics): keep emitted data out of dispatch listener fields
The EventEmitter operation collector read argument position 1 as the
listener for every event method, so a dispatch such as
bus.emit("ready", data) reported the data binding and its range as the
listener. Only registration and removal name a listener there; emit
passes its remaining arguments to listeners that already exist. Read the
listener argument only for register and remove operations.
Fixes#2574

* fix(javascript-semantics): read listener arguments only for listener-taking methods
removeAllListeners accepts only an optional event name, so gating the
listener argument on operation kind still reported an ignored second
argument as a listener. Gate on the methods whose argument position 1
names a listener instead: the registration methods, off, and
removeListener.
