Use Database spelling only to select a candidate. Reuse shared expression
provenance and indexed mutation facts to omit proven local constructors and
retain known SQLite API origins separately from uncertain names. Match ESM
default/namespace and CommonJS export forms without collapsing their identity.
Keep type-only import origins as ambiguous runtime values, including aliases.
Carry candidate interpretation through the worker schema and graph nodes and
edges with low confidence, explicit limitations and distinct identities.
Remove the name-only SQLite storage classifier. Other storage APIs retain
existing handling; PR4863's separate Map endpoint work is not integrated.
Validation: initial9negative controls fail unchangedf5fcf5216 while4positive
controls pass; final67focused checks/8files plus60provenance-consumer checks/
4files pass. Static/docs/discovery1557 pass. Two source reviewers clear after
correcting namespace constructor identity. Public CLI checks worker/schema
projection and separate exact/candidate identities with the same filename.
Twelve small completed CLI workflows preserve exact known-API replies and
remove false local-class storage facts. No speedup/large-case memory or real
SQLite execution claim. Direct eval's existing generic invalidation defect
remains tracked separately in #4875. Heavy tests/profiling remain stopped.
Additional consumer validation caught and corrected runtime import-equals
classification: require-mode import origins remain runtime values. Three new
SQLite controls cover runtime and erased import-equals forms; compiled
child-process CLI/MCP stdio workflows pass after the correction.
Fixes#4854
Select binding facts at reads without mixing whole-binding and temporal values. Share conditional activation rules, preserve partial expression order, and bound immutable ancestry work. Memoize temporal results within each query using initializer identity, capture point, budget and dependency proofs; preserve depth limits and source Evidence.
Fixes#3881
Fixes#3933. Part of #4027.
Normalize exact literals and configuration defaults through the shared primitive owner. Preserve tagged limits through member/destructuring projection and record encountered bounds in per-analysis state independently of later selected values. Remove the retained-value rescan and duplicate default reader. Preserve source Evidence, bounded/null values, aggregate wire capacity and complete endpoint lookup identities for query/trace/comparison.
Validated 66 focused and 932 semantic tests on the restored identical runtime; final public selection 7/7 adds an augmented large-endpoint acceptance (67 distinct focused cases across invocations). Full static/docs and fresh real Obsidian controls passed. Compact measurements and rejected attempts remain recorded.

Own skipped-write interpretation at definition collection, including conditional branches, loop iterations and optional-chain arguments. Remove the narrower initializer-only representation.
Fixes#2562
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.
Replace the implicit local-provenance fallback with explicit locally constructed values. Keep opaque results, parameters and caught values unknown; follow assignment and sequence results while retaining exact module aliases. Clarify that alias provenance does not represent transitive data taint.
Validation: 26 focused provenance/module-link tests, 135 semantic and graph-builder tests, six application module-relationship boundary tests, and the fast typecheck/lint gate.
* fix(javascript): resolve module-relative Worker URL references
* fix(javascript): validate Worker URL paths independently of suffixes
* fix(javascript): preserve directory-form Worker URL paths
* fix(javascript): unwrap type assertions in Worker URL references
* fix(javascript): validate Worker bindings before URL resolution
* fix(javascript): leave drive-letter Worker URLs unresolved
Use WHATWG file URL parsing before pathname decoding to detect drive-letter
forms whose resource identity depends on the unmodeled source URL scheme.
Preserve encoded and ordinary relative pipe paths, and cover false matches
through the compiled CLI and resolver boundary tests.
* fix(javascript): preserve Worker URL identity boundaries
Recognize known Worker bindings before filtering callee spellings so ESM
aliases and transparent constructor wrappers reach URL analysis. Keep
root-relative module URLs unknown without a modeled runtime base root.
Index direct source-local global writes with the shared mutation collector
before promoting URL and browser Worker constructors. Preserve lexical
shadowing and unrelated property identities, and exercise all three review
regressions through the compiled CLI.
* fix(javascript): invalidate mutated import.meta URL bases
Track source-local import.meta writes alongside ambient global writes so
Worker URL expressions keep an unknown base after a possible URL mutation.
Tag the identity roots independently and cover direct mutation and unrelated
property cases through the compiled CLI.
* fix(javascript): close Worker URL identity and pathname gaps
Resolve ambient object identities before appending written properties, and
retain possible source-local aliases across rebinding. Reuse intrinsic
invocation handling for aliased and bound mutators, array spreads, and
transparent TypeScript wrappers while preserving Electron write semantics.
Keep malformed-percent nested Worker URL pathnames unknown because the base
scheme is unavailable and Node rejects these file URLs. Preserve tolerant
HTML URL handling, valid escapes, and query/fragment evidence.
Cover the new cases and unrelated writes through the compiled CLI with
existing-file decoys. All 591 targeted tests and npm run check pass.
* fix(javascript): bound alias expansion and classify Worker paths
Join ambient identity projections instead of enumerating alias histories.
Memoize repeated value and provenance queries while preserving capture,
depth, and cycle-dependent uncertainty.
Keep Node Worker string arguments unresolved without filesystem or cwd
context, and admit qualified global URL constructors through identity checks.
Validate three 40-level alias branch shapes through the compiled CLI,
925 source tests, 25 CLI/boundary tests, and the full npm run check gate.
* fix(server): preserve partial Evidence target-content provenance
Pass the exact named contract returnsTargetContent flag through the shared partial-Evidence error delivery path introduced by the shortlist integration.
Exercise successful and failed recording through in-memory MCP for marked and unmarked contracts, preserving source payload and original failures. Observe both shared-handler emission and wire delivery so the SDK error-marker fallback cannot hide omissions. Suppressing the flag fails exactly the two marked cases.
Validation: check:fast, check, 736 semantic tests, 29 MCP transport/error tests and six compiled static Worker CLI journeys pass. No live target/provider execution or hosted publication.
* fix(javascript): structurally share semantic dependency proofs

* fix(javascript): bound value evaluation through nested closure aliases
A closure that aliases a binding from its enclosing scope evaluates that
binding once live and once at its own capture point. The capture cannot
order a binding declared in another function, so it fell back to a second
live evaluation. Only primitive results were kept, so every level of
nesting doubled the work: 20 nested closures over a non-constant value
took about 14 s, and a 443 KB generated wrapper reached the 300 s
analysis timeout.
Keep a live binding value when no caller could change it: no alias cycle
closes on or above the binding and the expression depth budget was not
reached. Bindings on a cycle are still re-evaluated, so their values and
reasons are unchanged.
Found while building a source-owned reproduction for #1847; that report's
worker heap exhaustion is a separate, already closed defect.
* fix(javascript): keep the expression depth budget for retained values
Reusing a retained composite value from any depth let a chain of wrappers
(s1 = {x: s0}, s2 = {x: s1}, ...) nest past the expression depth budget:
300 wrappers produced a 299-level value where the budget stops at 86, the
serialized IR grew quadratically, and 3,000 wrappers overflowed the stack
in JSON.stringify.
Record the expression depth at which each caller-independent value was
derived and reuse it only at that depth or shallower. A deeper reader
derives the value again and reaches the budget exactly as before. Closure
aliases read their outer binding at one depth on both paths, so nested
closures stay linear.
Reuse semantic module provenance for aliases and keep property path segments intact through Electron matching. Reject shadowed names and nested or dotted lookalikes. Reassigned and conditionally initialized module origins remain ambiguous, with their source origins retained.
Add a compiled CLI/stdio MCP regression for windows, preloads, context bridges, IPC operations, pairing, and source ranges. Validate 771 JavaScript domain tests, seven composition tests, the public acceptance workflow, build, and check:fast.
Fixes#1656
Track active bindings with per-evaluation push/pop instead of copying ancestor sets on every alias. Restore membership in finally so cycles and sibling branches keep their existing semantics.
Validation: 173 domain tests, compiled CLI/stdio MCP returned-reference acceptance, and check:fast pass. A randomized six-block Flameox experiment retained identical complete semantic output and reduced the bounded 112-alias analyzer median from 36.33 ms to 17.00 ms.
Repeated property writes to one object made member-mutation collection
cubic. Each write evaluated its target binding to rule out a primitive,
and every evaluation folded all earlier mutation paths, copying every
slot once per path. 2,000 writes to one object took 27 s and 4,000 took
203 s.
- A recorded write always leaves a non-primitive binding value, so only
the first write to a binding needs the primitive check.
- Apply mutation paths per slot in one pass with the same ordering
semantics instead of one full slot copy per path.

Remove forwarding wrappers and shadow aliases, migrate callers and verification scripts to their owners, and share one exhaustive semantic resource-bound projection.
Use one explicit object/array slot model and JSON-pointer property identity across mutation analysis, return projection, and semantic graphs. Require observed presence for discriminants and resolve writes only through retained object or array receivers.
BREAKING CHANGE: projected return fields require explicit presence and semantic object operations carry full property paths.
