Preserve CommonJS literal paths and confined ESM URL semantics, including package main fallback, directory intent, Unicode identity, and present opaque modules. Parse extraction inputs at their AST/source owner, retain skipped HTML and source-map coverage, and distinguish endpoint candidates from proven receiver facts. Version structural fingerprints with computed literal contents and propagate them through worker contracts. Reviewed fixes include #1810, #1840, #2642, #2700, #2702, #2714, #2803, #2960, #2968, #2986, #3035, and #3036. Validation: 158 resolver tests passed; public CLI/MCP module lookup controls, package-main/Unicode workflows, and six builtin workflows passed in the current compiled lane. Worker schema/fingerprint regressions passed. Large public pdf.js completion and real Electron analysis remain unverified.
