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
Give calls, captures, object operations, promises and effects one callable-owner tracker. Suspend a method while its computed key is evaluated in the enclosing callable; remove the capture-only downstream repair.

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 Remove superseded mutation representations and the ineffective per-markValue dedup layer.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.
Remove forwarding wrappers and shadow aliases, migrate callers and verification scripts to their owners, and share one exhaustive semantic resource-bound projection.
