* feat(flutter): identify Dart snapshot builds by pure APK parsing Add a flutter-provider family with one operation, identify_flutter_build, that reads an APK's lib/<abi>/libapp.so and libflutter.so through the hardened ZIP reader and reports build facts as observations: - The Dart VM snapshot hash, read 20 bytes after every snapshot magic (f5f5dcdc). The vm and isolate sections are cross-checked: agreeing sections collapse to one snapshot_hash, disagreeing sections keep every candidate with snapshot_hash null and partial coverage. - Per-ABI library digests and byte sizes, plus the engine library's GNU build-id note and any labeled 'Dart VM version' or Android clang/LLVM toolchain strings, verbatim; release builds without a version string report null rather than a guess. - The APK is digested before parsing so Evidence binds the observation to the exact input, and a target with no libapp.so reports not-detected with complete coverage. The scanner is streaming with explicit pending-magic and rescan bookkeeping, so chunk boundaries cannot double-count or drop sections, and magic-free streams never accumulate. No engine, no external lookups: the hash-to-SDK mapping stays with external datasets by design. Verified against Flutter Gallery 2.9.2 (112 MB, three ABIs): every ABI reports the same agreeing hash 65817c30a78bb44c3dc3771876b6010a from two sections, per-ABI build-ids, and the clang toolchain line; a plain aapt2-built APK reports not-detected with complete coverage. Scanner goldens come from the same libraries. READMEs carry the new 'Flutter apps' row in every supported language. * feat(flutter): inspect Dart AOT snapshots through the ELF symbol table Add inspect_dart_aot to the flutter family: for one ABI's libapp.so it locates the four _kDart*Snapshot* symbols through the ELF dynamic symbol table (ELF32 and ELF64 little-endian, bounds-checked reads; a payload without exported symbols is refused), reports each section's offset and size, validates data-section headers (magic, kind, length; instructions sections honestly report nulls for the fields their layout does not carry), and projects a bounded string pool from the isolate data section: distinct package: source URIs (the app's dependency inventory), dart: SDK URIs, and identifier-shaped tokens, each with counts, bounds, and partial coverage when truncated. The string pool is labeled as a byte-pattern projection, not deserialized cluster semantics: typed class and function recovery remains an SDK-specific parser, which the snapshot hash now unlocks. The ABI is caller-selected with a deterministic default (arm64-v8a, x86_64, then first available). Verified against Flutter Gallery 2.9.2: all four symbols on both ELF64 (arm64-v8a) and ELF32 (armeabi-v7a) images, header validation, hash agreement with identify_flutter_build, and a 756 package: / 201 dart: URI pool from the isolate data section; goldens in DartElf.test.ts come from the same libraries. * fix(flutter): own snapshots, bound image reads, and preserve cancellation Mirror the ownership bar the maintainers applied across the merged JEB, ADB, and Apktool PRs: - Copy the admitted APK into a provider-owned, read-only snapshot (EXCL create, chmod 0400) before digesting and parsing; every later read uses the snapshot, so a concurrently modified original cannot mix into one observation. The result reports the snapshot's byte size and digest. - Retain failed snapshot-root cleanup in a provider set and retry it on close(), throwing an aggregate error when a root is still owned; root removal is injectable so the retention is testable. - Allocate the AOT image buffer at exactly the declared library size before reading (bounded before allocation, not concat-after-stream), keep the 256 MiB ceiling, and check cancellation between digest and stream chunks through a captured abort reason. - Accept APK paths containing spaces (covered by a fixture test) and escape the ABI pattern's dash for v-mode regex compatibility. Also add tests for cleanup retention with close retry and for cancellation before any snapshot root is created. * docs(flutter): cover the Italian README with the Flutter row The Italian translation landed between the merged feature PRs; its table now carries every merged row plus this one, keeping its documentation-link set identical to README.md. * fix(flutter): make the ABI pattern portable for v-mode validators Use a hex-escaped hyphen in the ABI character class, matching the form the ADB portability fix uses, so clients compiling advertised schemas in unicodeSets mode accept the inspect_dart_aot input schema. * refactor(flutter): reuse shared harnesses and deduplicate the vertical The duplicate-detection gate (jscpd, 2.5% threshold) tipped to 2.51% with the flutter files added. Reuse the existing machinery instead of repeating it: - FlutterBuildAnalysisService delegates to executeProviderOperation, the shared admission/Evidence composition, instead of restating its body. - The CLI registers both commands from one table-driven spec. - Boundary tests use the shared serveCli and assertAdvertisedMcpContracts harnesses rather than hand-rolled equivalents. - The provider test consolidates the four payload-shape cases into one table-driven case; the service test uses one admission table and distinct phrasings. Duplicate lines fall from 2.51% to 2.48%, back under the gate. * fix(flutter): address review findings from real-app verification CassieFox23 verified the PR against three real F-Droid Flutter apps and a control app, and found five gaps. All are fixed and re-verified against cone (info.tangential.cone), one of the tested apps: - Build-id: the scanner now reads the descriptor length from the note header instead of assuming 20 bytes, so 8-byte ids from older toolchains parse; the schema accepts 8-128 hex characters. Verified against cone's readelf-reported ids on all three ABIs. - Compiler line: the toolchain capture bound rises from 200 to 500 characters, keeping cone's 262-character clang line verbatim. - Zero-byte libapp.so: the extraction target is created before streaming, so an empty entry yields a clean unsupported_target refusal for inspect_dart_aot and elf_header_valid: false with partial coverage for identify_flutter_build, instead of a raw ENOENT with code UNKNOWN. - Truncated library: identify_flutter_build marks fewer than two snapshot sections as partial coverage with a limitation naming the count, and a missing ELF magic gets its own limitation. - Docs: the default ABI preference now matches the code exactly (arm64-v8a, x86_64, x86, armeabi-v7a, then the rest alphabetically). Also: every test that read the author's /tmp/opencode goldens now builds a self-contained synthetic ELF64 image with dynsym, four snapshot symbols, two snapshot sections, and a string pool, so the suite runs anywhere; the verify lane now requires a present hex build-id per ABI instead of accepting null. * fix(flutter): address the Codex review findings Eight findings, all applied: - P1: SnapshotHashScanner keeps candidates in a Set (no quadratic Array.includes) with a 64-distinct-hash cap, so a hostile payload of magic+hash records cannot stall the scan or bloat the response. - P1: projectStringPool stops admitting new distinct entries once each category reaches twice its projection bound and reports collectionCapped; allocation and sorting now track the response, not the payload. - P2: ZIP reader rejections during entry iteration or entry streaming map into the typed error algebra (cancellation vs input refusal) instead of escaping as unhandled exceptions in both operations. - P2: magic_valid now marks coverage only for the *Data symbols; a complete four-symbol image with valid data magics reports complete coverage (the instruction symbols intentionally lack the magic). - P2: the MCP server closes the Flutter provider during shutdown, so a retained snapshot root is retried and reported, not leaked. - P2: LabeledStringScanner commits matches only when a printable run is delimiter-terminated; the carry grows to 600 bytes so a 500-character toolchain line survives any chunk boundary untruncated. - P2: both Flutter tool effects declare writesFilesystem: true; the owned APK snapshot and extracted libapp.so are temporary writes. - P2: the verify lane asserts every ABI agrees on exactly one snapshot hash instead of discarding the computed set. * fix(flutter): address the second Codex review round Nine findings on the first-round fixes: - P1: identify_flutter_build enforces a cumulative extraction budget (768 MiB) across every library entry, not just per library, so an APK with many ABIs cannot stream an unbounded total. - P1: a single NUL-free printable run stops materializing at 1024 bytes and marks the pool capped, so an adversarial one-run section cannot allocate unbounded strings. - P1: ELF cString bounds the NUL-terminator scan to the name maximum plus one, so malformed symbol tables cannot scan the whole image per entry. - P2: mapReaderFailure distinguishes ArtifactReaderFailure texts — budget/limit rejections map to resource constraints, integrity failures (CRC/overlap/signature) to their own input refusal — instead of collapsing all reader failures into one message. - P2: the labeled-string carry is cleared when a delimiter commits a run, so consecutive toolchain lines are never concatenated. - P2: string-pool counts are renamed *_count_at_least and documented as lower bounds, because capped collection discards values beyond twice the projection bound. - P2: inspect_dart_aot marks hash disagreements, non-pair source counts, and candidate-cap saturation as partial coverage. - P2: only valid lowercase-hex hash records count as snapshot sources; complete magic records with non-hex fields do not inflate agreement. - P2: the per-entry size refusal in inspect_dart_aot moves after ABI selection, so an oversized unselected ABI no longer refuses a small request. * fix(flutter): address the third Codex review round Five findings: - P2: the owned snapshot revalidates the source after the copy (size, mtime, inode), so an in-place replacement or swap mid-copy refuses the observation instead of publishing mixed bytes. - P2: a failed ZipArtifactReader close retains the snapshot root for close() retry instead of silently swallowing the descriptor leak, in both operations. - P2: snapshot headers are parsed within their symbol bounds and a symbol smaller than the 16-byte header reports magic_valid false, so trailing-image bytes can no longer fake a valid data section. - P2: the verify lane counts provider.close() cleanup failures as lane failures instead of certifying a run with retained roots. - P2: LabeledStringScanner reports toolchain_capped when further distinct matching lines are observed past the 4-line projection; identify marks such results partial with a naming limitation. * fix(flutter): address rounds three and four of the Codex review Round three (one missed finding) plus round four (five findings): - P2: the GNU build-id note descriptor size is decoded from all four bytes of the little-endian field, rejecting nonzero high bytes instead of masking them to 16 bits. - P1: the Flutter MCP handlers route through createContractToolHandler and the session's analysisAdmission, so close_binary and snapshot operations drain in-flight Flutter calls instead of racing them. - P2: the owned-snapshot copy is a streamed, abort-checked write (no copyFile), so cancellation stops the write promptly while the source-identity revalidation (size, mtime, inode) still guards against mid-copy replacement. - P2: identify marks any snapshot_hash_sources value other than exactly two as partial, matching the inspection path's pair requirement. - P2: the verify lane refuses to run without --apk (exit 2) instead of printing a false-green pass, and the engine check requires every libapp-carrying ABI to have a present libflutter with a valid hex build-id rather than filtering missing engines away vacuously. * fix(flutter): address the fifth Codex review round Six findings plus the upstream duplication baseline: - P2: the flutter-provider kind reports available in the capability inventory, so binary_session no longer lists always-registered Flutter tools as provider_missing. - P2: printable runs that exceed the 1024-byte cap are discarded at their delimiter instead of emitting their truncated prefix as a fabricated observation. - P2: ELF symbols must fit inside the file-backed portion of their PT_LOAD segment (p_filesz), so addresses in gaps or BSS are refused instead of accepting unrelated bytes. - P2: the build-id carry spans the complete 80-byte maximum note (16-byte header + 64-byte descriptor) so chunk-boundary splits cannot drop the first byte. - P2: the labeled-string carry is sized for the toolchain pattern's true 605-byte maximum, not the previous 600. - P2: the AOT completeness predicate requires exactly two sources and one candidate unconditionally, so zero-source images with valid data magics report partial instead of complete. Also: the shared ELF fixture builder and snapshot-section helper moved to a dedicated FlutterTestFixtures module, eliminating cross-file test duplication; jscpd now passes at 2.50% while main sits at 2.52%. * fix(flutter): address the sixth Codex review round Five findings: - P2: snapshot-hash scanning is bounded to the exported data symbols' byte ranges, so decoy or stale magic/hash sequences elsewhere in the image cannot inflate source counts or contribute candidates. - P2: labeled-string runs longer than the carry bound are rejected instead of truncated, preventing a regex prefix from being published as a verbatim source string. - P2: the AOT image reread checks cancellation between file reads and before the synchronous parsing stage, so a cancelled caller cannot receive a success from a completed 256 MiB read. - P2: the verify lane requires exactly two snapshot sources per ABI, matching the provider's pair requirement, instead of accepting any count >= 2. - P2: ELF section and program header entry sizes are validated against the class-defined minimum widths before walking either table, so undersized entries cannot cause field reads to cross into neighboring bytes. * fix(flutter): address the seventh Codex review round Six findings: - P2: data-symbol ranges are deduplicated by offset and size, so aliased symbols mapping to the same bytes are scanned once and the result marks partial coverage with a limitation naming the shared range. - P2: openEntrySafely forwards return/throw to the underlying Readable's iterator, so an early for-await exit closes the ZIP entry stream and releases its producer instead of leaking a backpressured pipe. - P2: inspect_dart_aot now reports snapshot_hash_candidates and snapshot_hash_sources alongside snapshot_hash, so a null hash from conflicting evidence is distinguishable from missing hash data. - P2: overlong printable runs only set toolchain_capped when they begin with a recognized label prefix (Dart VM version: or Android (); other long strings such as license text are skipped without marking partial. - P2: readElfSymbol falls back to PT_DYNAMIC/DT_SYMTAB when section headers are absent (e_shnum 0, ET_DYN), so stripped Flutter libraries with exported snapshot symbols are no longer refused; the dynamic table is bounded by DT_STRSZ, DT_SYMENT, and the image end. - P2: the verify lane exercises inspect_dart_aot for every ABI carrying libapp.so, not just the preferred default. * fix(flutter): address the eighth Codex review round Five findings: - P2: each data-symbol range gets a fresh SnapshotHashScanner so the carry from one noncontiguous slice cannot fabricate a record spanning into the next; results are aggregated after scanning. - P2: dynsym name lookups are bounded to the linked string table — st_name offsets outside the table and terminators beyond it are rejected instead of reading unrelated payload bytes as symbol names, in both the section-header and PT_DYNAMIC paths. - P2: identify_flutter_build routes its reader.entries and reader.open calls through the same collectEntriesSafely and openEntrySafely wrappers as inspect_dart_aot, so malformed ZIPs surface as input refusals instead of AnalysisProtocolError. - P2: mapReaderFailure recognizes ArtifactReaderFailure texts carrying a cancelled reason, mapping them to AnalysisCancelledError instead of AnalysisInputError. - P2: the cumulative extraction cap is enforced inside the chunk loop, not after each library completes, so refusal happens before the remaining bytes are streamed and hashed. * fix(flutter): harden streaming, sizes, and cancellation after self-review Four issues found in a systematic self-audit across all bug classes from eight Codex rounds: - createReadStream in both the digest function and the owned-snapshot copy now receives the AbortSignal directly, so cancellation aborts the filesystem read at the source instead of waiting for the next chunk to arrive on a slow filesystem. - The owned snapshot enforces a 2 GiB APK-level size cap before any copy I/O, so a path pointing at an enormous file is refused before disk usage grows. - identify_flutter_build preflights the sum of declared entry sizes against the 768 MiB cumulative budget, refusing before any ZIP extraction when the declared total already exceeds it. - The LabeledStringScanner triple result() call is collapsed to a single invocation (the previous code called result() three times in the emission, relying on end() being idempotent). No behavior change for valid inputs; all 36 tests, check:fast, and the cone verify lane pass unchanged. * fix(flutter): require structurally parseable ELF headers for complete coverage CassieFox23's third corrupt-header case: an ELF with valid magic but zeroed section/program header offsets passes the 4-byte magic check and the byte scanner still finds hash patterns in the data sections, so identify_flutter_build reports complete coverage for a structurally broken file. The elf_header_valid check now also verifies beyond the magic: e_type must be a known value (ET_REL/ET_EXEC/ET_DYN), at least one of e_shoff/e_phoff must be non-zero, and at least one of e_shnum/e_phnum must be non-zero. A file with valid magic but zeroed structure reports partial coverage with the existing ELF-magic limitation. * fix(flutter): validate ELF and snapshot coverage Share bounded ELF header parsing between identification and inspection. Accumulate headers across ZIP chunks and validate table entry widths and extents before claiming complete identification coverage. Bind AOT hashes to the exported VM and isolate headers, validate stored snapshot lengths including the magic bytes, and preserve partial evidence for missing, malformed, aliased, or overlapping data headers. Preserve native stream cancellations and APK resource constraints across both operations. Bound snapshot copies while streaming and retain useful input-failure diagnostics and lower-bound count wording. Validation: 72 focused tests; check:fast; check including formatting; docs:check; test discovery; jscpd; real cone APK and non-Flutter control on Linux. Verified CLI/MCP parity for valid and corrupted ELF headers and AOT inspection across three ABIs. Native Windows and macOS were not run. * fix(flutter): unify artifact ownership and bound ELF evidence * fix(flutter): preserve ELF provenance and partial coverage Read GNU build IDs only from bounded ELF note ranges and retain conflicting candidates. Preserve source versus owned storage failures and honor cancellation through parsing and final cleanup. Separate snapshot structure from string-pool coverage. Verify every Gallery ABI with digest-bound engine labels and URI counts, and document the supported snapshot-kind layout. --------- Co-authored-by: REA Contributor <contributor@rea.tools> Co-authored-by: morluto <76467478+morluto@users.noreply.github.com>

Melihat fitur dalam suatu aplikasi yang ingin Anda hadirkan di produk sendiri? Minta agen Anda menyelidikinya menggunakan REA. REA dapat memeriksa aplikasi tanpa kode sumbernya, menjelaskan cara kerja fitur tersebut, menunjukkan bukti, dan membangun versi untuk proyek Anda.
REA menghubungkan agen Anda dengan berbagai alat untuk memeriksa biner native, aplikasi JavaScript dan Electron, assembly .NET, serta situs web. Anda juga dapat menggunakan alat yang sama dari terminal. Analisis dijalankan secara lokal, dan hasilnya mencakup bukti serta keterbatasan yang mendasari setiap kesimpulan.
Proses penyiapan mendaftarkan REA ke agen Anda dan memasang instruksi alur kerja yang sesuai. Analisis native dapat menggunakan instalasi Hopper, Ghidra, atau IDA yang sudah ada. Proses penyiapan juga dapat memasang Hopper secara opsional setelah mendapatkan persetujuan. Analisis JavaScript statis tidak memerlukan mesin analisis native.
Kunjungi situs web REA untuk mendapatkan petunjuk penyiapan, panduan bergambar, dan studi kasus nyata.
Mulai Cepat
Siapkan agen Anda
Dengan Node.js dan npm yang telah terpasang, jalankan:
npx rea-agents setup
Pilih agen yang ingin digunakan, tinjau perubahan yang diusulkan, lalu setujui perubahan tersebut. Proses penyiapan menambahkan server MCP REA dan instruksi alur kerja yang sesuai, serta membuat cadangan konfigurasi yang sudah ada. Setelah itu, mulai ulang agen Anda.
Penyiapan mendukung Claude Code, Codex, Cursor, Gemini CLI, Grok Build, dan agen lainnya. Lihat instalasi dan penyiapan untuk konfigurasi penyedia dan pendaftaran MCP secara manual.
Minta agen Anda
Pahami cara kerja pencarian di aplikasi Notes, tunjukkan buktinya, dan buat fitur serupa untuk proyek saya.
Ganti Notes dengan aplikasi target dan fitur yang ingin Anda pahami.
Gunakan terminal
Periksa direktori aplikasi JavaScript/Electron yang telah diekstrak atau berkas ASAR:
npx -y rea-agents@latest analyze-javascript-application /absolute/path/to/app --json
Hasilnya mencakup modul, impor, batas antarkomponen Electron, dan bukti yang mendasarinya. Ganti jalur tersebut dengan lokasi target Anda, misalnya "D:/apps/example" di Windows.
Untuk memasang perintah rea agar dapat digunakan secara rutin:
npm install --global rea-agents
rea --help
Untuk analisis native, konfigurasikan penyedia terlebih dahulu. Lihat Panduan CLI dan Bukti untuk perintah native, pemilihan penyedia, snapshot, dan pembuatan skrip.
Perbarui REA
REA berkembang dengan cepat, dan rilis baru sering menyertakan perbaikan bug. Pastikan instalasi Anda selalu diperbarui.
Untuk CLI yang dipasang melalui npm install --global atau bun add --global:
rea update
Pembaruan global dengan Bun memerlukan Bun 1.2.17 atau yang lebih baru. Pada rilis Bun yang lebih lama, perbarui Bun secara manual sebelum menjalankan rea update.
Untuk memperbarui pendaftaran agen dan skill Anda, jalankan perintah penyiapan yang ditampilkan oleh proses pembaruan.
Jika Anda menggunakan npx, perbarui penyiapan agen dengan:
npx rea-agents@latest setup
Tinjau perubahan penyiapan dan mulai ulang agen Anda. Untuk menjalankan perintah CLI sekali pakai, gunakan npx rea-agents@latest diikuti dengan perintah yang diinginkan. Dengan Bun, gunakan bunx rea-agents@latest sebagai pengganti npx rea-agents@latest.
Cara Kerja REA
Agen Anda memanggil REA melalui MCP untuk memeriksa target dan menelusuri kode yang relevan. REA mengembalikan temuan beserta bukti pendukungnya. Agen kemudian menggunakan temuan tersebut untuk mengajukan pertanyaan lanjutan, menjelaskan perilaku, atau menulis dan menguji implementasi.
Perintah CLI menggunakan alur kerja yang sama.
Buka ilustrasi dalam ukuran penuh.

FAQ
Agen apa saja yang dapat menggunakan REA?
Agen apa pun yang mendukung server MCP lokal dapat menggunakan REA. Proses penyiapan mengonfigurasi agen yang didukung. Klien lain dapat menggunakan pendaftaran MCP manual.
Apakah saya memerlukan Hopper, Ghidra, atau IDA?
Analisis native mendalam menggunakan salah satu dari ketiganya. Pemeriksaan JavaScript dan .NET statis dapat dilakukan tanpa mesin analisis native.
Proses penyiapan dapat memasang Hopper setelah memperoleh persetujuan. Ghidra dan IDA menggunakan instalasi yang sudah tersedia. Lihat penyiapan penyedia.
Apakah saya harus menjalankan Hopper terlebih dahulu?
REA akan menjalankan Hopper saat suatu operasi membutuhkannya. Di macOS, dialog saat pertama kali dijalankan mungkin meminta Anda memilih mode demo atau mengaktifkan lisensi.
Apa fungsi memasang skill dari skills.sh?
Skill tersebut menyediakan instruksi investigasi untuk agen Anda. Gunakan npx rea-agents setup untuk mendaftarkan server MCP REA dan memasang instruksi yang sesuai, lalu mulai ulang agen Anda.
Lihat instalasi khusus skill.
Kode seperti apa yang dihasilkan REA?
Analisis native menghasilkan pseudocode dan assembly. Analisis JavaScript/Electron memulihkan modul dan hubungan antarmodulnya. Agen Anda menggunakan temuan tersebut untuk menulis dan menguji implementasi. Contoh penggunaan menyediakan contoh yang telah dikerjakan.
Apakah REA mengunggah aplikasi saya?
REA menganalisis target secara lokal. Agen Anda menerima hasil alat, sedangkan penyedia model yang digunakannya memiliki kebijakan datanya sendiri.
Apa yang harus saya lakukan jika menemukan bug?
Perbarui terlebih dahulu. Rilis terbaru mungkin sudah memperbaiki masalah tersebut.
Untuk CLI yang dipasang melalui npm install --global atau bun add --global:
rea update
Untuk penyiapan agen melalui npx:
npx rea-agents@latest setup
Jika Anda menggunakan agen, selesaikan pembaruan penyiapan dan mulai ulang agen tersebut.
