Quentin Limo e4d3e1399d feat(flutter): identify Dart snapshot builds and inspect AOT payloads by pure APK parsing (#1582)
* 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.

Hai visto una funzionalità in un'app che vorresti nel tuo prodotto? Chiedi al tuo agente di analizzarla con REA. Può ispezionare l'app senza il suo codice sorgente, spiegare come funziona la funzionalità, mostrare le prove e realizzare una versione per il tuo progetto.

REA collega il tuo agente a strumenti per ispezionare binari nativi, app JavaScript ed Electron, assembly .NET e siti web. Puoi usare gli stessi strumenti anche dal terminale. L'analisi viene eseguita localmente e i risultati includono le prove e i limiti dietro ogni conclusione.

La configurazione registra REA con il tuo agente e installa le istruzioni di workflow corrispondenti. L'analisi nativa può usare un'installazione esistente di Hopper, Ghidra o IDA; la configurazione può installare opzionalmente Hopper previa approvazione. L'analisi statica JavaScript non richiede alcun motore di analisi nativo.

Visita il sito web di REA per istruzioni di configurazione, guide illustrate e veri casi studio.

Avvio rapido

Configura il tuo agente

Con Node.js e npm installati, esegui:

npx rea-agents setup

Scegli i tuoi agenti, rivedi le modifiche proposte e approvale. La configurazione aggiunge il server MCP di REA e le istruzioni di workflow corrispondenti, con backup della configurazione esistente. Riavvia quindi il tuo agente.

La configurazione supporta Claude Code, Codex, Cursor, Gemini CLI, Grok Build e altri agenti. Vedi installazione e configurazione per la configurazione dei provider e la registrazione manuale MCP.

Chiedi al tuo agente

Spiega come funziona la ricerca nell'app Note, mostrami le prove e realizza
una funzionalità simile per il mio progetto.

Sostituisci Note con la tua app di destinazione e la funzionalità che vuoi capire.

Usa il terminale

Ispeziona una directory di app JavaScript/Electron estratta o un ASAR:

npx -y rea-agents@latest analyze-javascript-application /percorso/assoluto/verso/app --json

Il risultato include moduli, import, confini Electron e le relative prove. Sostituisci il percorso con il tuo bersaglio, ad esempio "D:/apps/example" su Windows.

Per installare il comando rea per un uso regolare:

npm install --global rea-agents
rea --help

Per l'analisi nativa, configura prima un provider. Vedi la guida CLI ed Evidence per i comandi nativi, la selezione del provider, gli snapshot e lo scripting.

Aggiorna REA

REA cambia rapidamente e le nuove versioni includono correzioni di bug frequenti. Tieni aggiornata la tua installazione.

Per una CLI installata con npm install --global o bun add --global:

rea update

Gli aggiornamenti globali con Bun richiedono Bun 1.2.17 o versioni successive. Con una versione precedente di Bun, aggiorna Bun manualmente prima di eseguire rea update.

Per aggiornare le registrazioni del tuo agente e lo skill, esegui il comando di configurazione mostrato dall'aggiornamento.

Se usi npx, aggiorna la configurazione del tuo agente con:

npx rea-agents@latest setup

Rivedi le modifiche di configurazione e riavvia il tuo agente. Per comandi CLI singoli, usa npx rea-agents@latest seguito dal comando. Con Bun, usa bunx rea-agents@latest al posto di npx rea-agents@latest.

Come funziona REA

Il tuo agente chiama REA tramite MCP per ispezionare il bersaglio e tracciare il codice rilevante. REA restituisce i risultati con le relative prove. L'agente li usa per fare domande di approfondimento, spiegare il comportamento o scrivere e testare un'implementazione. Anche i comandi CLI usano gli stessi workflow.

Flusso di indagine REA: il tuo agente pone domande su un bersaglio locale, REA lo ispeziona e ne traccia il codice usando strumenti di analisi, e l'agente usa il codice, i riferimenti e gli elementi sconosciuti restituiti per spiegare, implementare e testare.

Apri la figura a dimensione intera.

FAQ

Quali agenti possono usare REA?

Qualsiasi agente che supporti server MCP locali. La configurazione configura gli agenti supportati; altri client possono usare la registrazione MCP manuale.

Ho bisogno di Hopper, Ghidra o IDA?

L'analisi nativa profonda ne usa uno. L'ispezione statica di JavaScript e .NET funziona senza un motore di analisi nativo. La configurazione può installare Hopper previa approvazione; Ghidra e IDA usano le tue installazioni esistenti. Vedi configurazione provider.

Devo avviare Hopper per primo?

REA avvia Hopper quando un'operazione ne ha bisogno. Su macOS, una finestra di dialogo al primo avvio potrebbe chiederti di scegliere la modalità demo o di attivare la licenza. Vedi avvio di Hopper e risoluzione dei problemi.

Cosa fa l'installazione dello skill da skills.sh?

Lo skill fornisce istruzioni di indagine per il tuo agente. Usa npx rea-agents setup per registrare il server MCP di REA e installare le istruzioni corrispondenti, quindi riavvia il tuo agente. Vedi installazione solo skill.

Quale codice restituisce REA?

L'analisi nativa restituisce pseudocodice e assembly. L'analisi JavaScript/Electron recupera moduli e le loro relazioni. Il tuo agente usa questi risultati per scrivere e testare un'implementazione; gli showcase offrono esempi concreti.

REA carica la mia app da qualche parte?

REA analizza i bersagli localmente. Il tuo agente riceve i risultati degli strumenti e il suo provider di modello ha la propria politica sui dati.

Cosa devo fare se trovo un bug?

Aggiorna prima; una release recente potrebbe averlo già risolto.

Per una CLI installata con npm install --global o bun add --global:

rea update

Per la configurazione dell'agente tramite npx:

npx rea-agents@latest setup

Se stai usando un agente, completa l'aggiornamento della configurazione e riavvialo. Riprova lo stesso task. Se il problema persiste, apri un issue con la tua versione di REA, il tipo di bersaglio, i passaggi per riprodurlo e l'output di errore.
