Use zip.js's parsed symlink fact for inventory and open refusal. Treat an unmatched Godot trailer as an unconfirmed candidate while preserving failures for confirmed malformed packs. Report entropy path-resolution failures at the selected-input boundary. Separate Go header discovery from inline string extents in ELF and Mach-O, and apply the aggregate content allowance after validating real source ranges. Normalize binary plist UID widths through the existing scalar-copy owner, budget exact clone growth, preserve source identity, and refuse inexact UIDs. Validation: 389 distinct tests passed, one Linux /proc test skipped on Darwin; build, typecheck/lint, docs, single-thread formatting, and discovery (2142 files) passed. CLI/MCP Go fixtures and public ZIP/Godot/keyed-archive workflows ran. Real producer prevalence and external provider execution were not established. Repeated ordinary keyed-archive CLI inventory facts and estimated reply tokens were equal before/after. Warm median elapsed was 0.5166s / 0.5177s; no speed claim.
