Link original DEX native declarations to per-ABI function exports and relocated static JNI table candidates through shared CLI/MCP workflows. Preserve global attribution ambiguity, exact provenance, partial coverage and retained Evidence; default MCP delivery to bounded summaries with filtered/batch pages. Use one immutable ELF relocation decoder with streaming IL2CPP materialization, cooperative bounded export/version parsing and bounded JNI state. Reuse validated session inventories without loading target libraries or executing JNI code. Validation: relevant type/lint/build and parser/domain/public CLI/MCP regressions; genuine four-ABI NDK fixtures and independent library/slot oracles; actual JDK/JADX Conscrypt workflows with retained-source removal. Full measurements and limitations are recorded in docs/verification/android-jni-bindings-2026-10-27.md. Closes #6403.
