* feat(native): decode Android .note.android.ident ELF notes Decode Android NDK NT_ANDROID_TYPE_IDENT (.note.android.ident, owner Android, type 1) notes in inspect_elf_notes across legacy 4-byte and modern >=132-byte descriptors with bounded TextBudget accounting. * fix(native): isolate Android note scan budget test, scope contract import, and add feature spec * test(native): use domain tool contract in elfNotesMcp boundary test

# Implementation plan
|
|
|
|
## Boundary and contract
|
|
|
|
Extend `ELF_NOTE_TYPE_NAMES`, `androidNoteTypeName`, and `elfNotesSchema` in
|
|
`src/domain/native/elfNotes.ts` with `"android_ident"` and nullable
|
|
`android: { android_api, ndk_version, ndk_build_number }` on each note entry.
|
|
|
|
Implement `scanAndroidIdentSlot` and `decodeAndroid` in
|
|
`src/native/elf/ElfNoteParser.ts`, invoked from `toEntry` alongside `decodeGnu`
|
|
and `decodeCore`. Cache the 128-byte fixed-slot scan per descriptor range under
|
|
`android:${byteOffset}:${length}` in `TextBudget.scans`, charge `scanned` once
|
|
per distinct range, and charge retained `ndk_version` and `ndk_build_number`
|
|
lengths to `TextBudget.used`. Update the `inspect_elf_notes` description in
|
|
`src/contracts/native/binaryDiagnosticsToolContracts.ts` and the owning guide
|
|
[ELF note tables](../../../elf-notes.md).
|
|
|
|
## Incremental work and validation
|
|
|
|
1. Extend `src/domain/native/elfNotes.ts` and add unit tests in
|
|
`src/domain/native/elfNotes.test.ts`.
|
|
2. Add `androidIdentNote` fixture support in `src/native/elf/ElfNotes.fixture.ts`
|
|
and implement `decodeAndroid` in `src/native/elf/ElfNoteParser.ts` with
|
|
endianness, malformed-slot degradation, and `TextBudget` accounting tests in
|
|
`src/native/elf/ElfNoteParser.test.ts`.
|
|
3. Add MCP boundary tests (`tests/boundary/mcp/elfNotesMcp.test.ts`) and
|
|
CLI/stdio-MCP parity acceptance tests (`tests/acceptance/elfNotesAndroid.test.ts`)
|
|
importing `BINARY_DIAGNOSTICS_TOOL_CONTRACTS`.
|
|
4. Update [ELF note tables](../../../elf-notes.md) and the feature specification
|
|
index; pass formatting, static, typed-lint, test, and documentation gates.
|
|
|
|
## Effects and compatibility
|
|
|
|
`inspect_elf_notes` / `inspect-elf-notes` entries gain additive `"android_ident"`
|
|
and nullable `android` fields while preserving existing `gnu`, `core`, and
|
|
raw `descriptor` provenance. No external tools, network calls, or target
|
|
execution are introduced.
