* fix(javascript): preserve literal percent runtime paths * fix(javascript): ignore resolve prefixes before the final anchor * fix(electron): retain application roots for loadFile declarations * fix(electron): resolve loadFile from enclosing application package * fix(electron): retain outer application root across package scopes * fix(electron): derive application ownership from inventoried packages * fix(electron): retain resolved package entrypoint ownership * fix(electron): preserve competing application ownership * fix(electron): retain invalid and omitted runtime ownership * fix(electron): preserve omitted module ownership and runtime paths * fix(electron): preserve proven roots before confining page paths * fix(electron): retain possible owners behind missing imports * fix(electron): distinguish absent imports and owned page candidates * fix(electron): keep unavailable JSON out of owner gaps * fix(electron): retain exact loader formats and default entry status * fix(electron): retain unavailable entrypoint ownership candidates * test(ghidra): preserve Windows Node probe prerequisites * test(ghidra): assert cancellation during profile shutdown * fix(electron): separate examined imports from frontend ownership * fix(electron): retain unavailable directory entrypoint owners * test(jeb): retain Linux ownership prerequisite in isolation * fix(javascript): retain unchecked loader ownership and literal main paths * fix(javascript): preserve runtime paths and call-site module aliases * fix(javascript): bound module alias traversal and preserve projections * fix(javascript): retain host module and nested artifact path boundaries * fix(javascript): preserve ESM and archive module loader provenance * test(javascript): distinguish unmapped containers from missing exports * fix: retain default module aliases and Electron builtin imports * fix: preserve host file URL and inward ASAR ownership * fix: preserve CommonJS file URL classification in CI fixtures * fix: retain bound module loaders and Windows entrypoint uncertainty * fix: retain ASAR uncertainty and invalidate changed Electron app roots * fix(javascript): retain ownership uncertainty across loader boundaries * fix(javascript): preserve loader sources and bound alias queries * fix(javascript): retain destructured loader sources * fix(javascript): preserve loader uncertainty at resolution boundaries * fix(javascript): preserve callable and package launch ownership * fix(javascript): preserve captured values across member reads * test(process): assert tagged filesystem cancellation failures * fix(javascript): preserve inventory bases and invocation read timing * fix(javascript): preserve ownership across indirect and unread loads * test(javascript): order fixture directory creation on Windows * test(javascript): share ordered filesystem fixture writer * fix(javascript): unify loader provenance and package validation * fix(javascript): preserve captured Node require loader values * fix(javascript): preserve loader invocation authority * fix(javascript): verify generic loader invocation authority * fix(javascript): preserve conditional loader method alternatives * fix(javascript): require proven factories for source association * fix(javascript): honor replaced Electron app path setters * fix(javascript): prove path and assignment source ownership * fix(javascript): retain native delegate eligibility through shared writes * fix(process): settle stale baseline errors after confirmed absence * fix(javascript): preserve assignment and path boundary evidence * fix(javascript): prove source-directory resolve anchors * fix: preserve application path provenance and portable schemas * fix(javascript): retain CommonJS exported setter effects * fix: isolate Linux identity observations and retain native module exports * fix(javascript): preserve published app and helper provenance * fix(javascript): normalize typed stores and native path fixtures
