Release 0.6.0

Give duplicate Dart method names unique r2 flags and function names
r2 flag names are unique, so flagging a second function with a repeated Dart name (e.g. Native._anon_closure) moved the flag away from the first one, and current r2's af then named it after the Mach-O sym.func.* flag. Suffix repeats with their address, use the same names for afs, and rename analyzed functions after the af pass. Also skip var recovery, call-following and jump tables in the signature af pass (AuthPass -AAA 47s -> 29s) and raise R2R_TIMEOUT to 60s.

 [![ci](https://github.com/trufae/r2flutter/actions/workflows/ci.yml/badge.svg)](https://github.com/trufae/r2flutter/actions/workflows/ci.yml)

-<br />
-The default parser uses radare2 for binary loading but does not rely on existing
-r2 analysis (`afl`/`aflj`); Dart-aware code analysis is opt-in with `-AAA`. The
-Dart parser is self-contained C code (no Dart VM headers or libs) and reads AOT
-snapshots, data images, clusters, ObjectPool records, and instruction tables
-directly.
-</p>
+**r2flutter brings Dart and Flutter AOT awareness to [radare2](https://rada.re/).**
+It reads the snapshots embedded in release builds and turns their metadata into
+useful names, addresses, strings, classes, and references for reverse
+engineering. It is available both as the `bin/r2flutter` command-line tool and
+as an `r2flutter` command inside radare2.

-## Features
+Give it an extracted Android `libapp.so`, an Android directory containing one,
+an iOS `.app` bundle, or a direct AOT binary. AArch64 is the primary analysis
+target. The parser has in-tree layouts for Dart 2.10 through 3.12; see the
+[support matrix](doc/support.md) for platform and version details.

- Support iOS and Android Flutter apps
- Accepts direct binaries, Android directories with `libapp.so`, and iOS `.app`
-  bundles with `Frameworks/App.framework/App`
- Derives names/addresses from Dart snapshots, data images, clusters,
-  ObjectPool records, and instruction tables
- Recovers snapshot headers, functions, classes, fields, string refs, xrefs,
-  reconstructed ObjectPool PP data, and best-effort SBOM/component reports
- Uses radare2 for binary loading while keeping the Dart parser self-contained
- Prints text, JSON, or radare2 command output for supported dump actions
+## What it can do

-## Supported Dart/Flutter Versions
+- Find Dart AOT snapshots in Flutter apps and supported standalone Dart
+  containers.
+- Recover snapshot headers, functions, classes, fields, type names, strings,
+  ObjectPool values, instruction-table entries, and metadata references.
+- Apply recovered names, flags, comments, classes, and code references to a
+  radare2 session.
+- Emit readable text, JSON for automation, or radare2 commands for importing
+  into another session.
+- Use Flutter's `--save-obfuscation-map` output to restore recovered names.

-r2flutter supports Dart AOT snapshots from **Dart 2.10.0 to 3.10.7** (Flutter 1.22.x to 3.38.x).
+r2flutter is a metadata and analysis aid, not a Dart source-code decompiler.
+Recovery depends on what survived in the AOT snapshot, so some names and
+references are necessarily best effort.

-The detailed support matrix, including tag-style changes and Android/iOS-specific notes, lives in [doc/support.md](doc/support.md).
+## Build and install

-Unknown snapshot hashes default to the v3.9.2 profile with ObjectHeader tag encoding.
+You need `radare2` 6.2.2 or newer (or a git build of 6.2.1), including its
+development headers, and `r2` must be on `PATH`. The build obtains the
+required flags from `r2 -H`. Older radare2 versions lack the `ic+` attribute
+support used to register class metadata and are rejected at compile time.

-## Building
-
-This project can be used from the system shell or directly integrated inside radare2:
-
-```bash
+```sh
+git clone https://github.com/trufae/r2flutter.git
+cd r2flutter
 make
 ```

-To get the plugin inside your r2 shell do that:
+The command-line tool is now ready at `bin/r2flutter`.

-```bash
+To install the radare2 plugin for your user account:
+
+```sh
 make user-install
 ```

-## Usage
+For a system-wide command-line tool and plugin, build the plugin first and
+then use the usual install prefix:

-```bash
-Usage: bin/r2flutter [options] <libapp_path_or_dir>
-Modifiers:
-  -h                    Show help
-  -j                    Output in JSON format
-  -n                    Heuristic fallback for unknown functions; may assign wrong names
-  -q                    Compact output; suppress non-essential detail
-  -r                    Output r2 commands for the selected action
-  -v                    Verbose (stderr debug info)
-  -vv                   More verbose (dump headers)
-  -V                    Show version
-Actions:
-  -A                    Analyze Dart snapshot and apply flags/comments
-  -AA                   Analyze with field extraction enabled
-  -AAA                  Run Dart-aware code analysis and recover code refs

+```sh
+make r2
+sudo make install
 ```

-`bin/r2flutter` runs one action per invocation. Directory inputs resolve Android
-first (`libapp.so`), then iOS (`Frameworks/App.framework/App`).
+## First look at an app

-`-f` and the `-A` analysis flow skip loader-provided ELF/Mach-O stub symbols; radare2 already gets those from `RBin`, so `r2flutter` stays focused on Dart-derived metadata.
+Start with the snapshot header. It confirms that r2flutter found a Dart AOT
+image and shows the detected Dart profile:

-`-m` consumes the JSON array emitted by Flutter/Dart `--save-obfuscation-map`. r2flutter inverts that mapping and applies it to recovered functions, instruction-table names, classes, fields, and method owners.
-
-`-n` is intentionally opt-in. It consumes `package:` and `dart:` strings from the data image as a sequential fallback for otherwise unnamed functions, so it can produce plausible but incorrect names when the string order does not match the instruction table.
-
-`-D` forces the Dart profile used for layout/CID decoding without patching the
-input binary. Pass either a known 32-byte snapshot hash or a supported Dart
-version such as `3.8.1`.
-
-`-S` emits a best-effort recovered component report, not a complete dependency
-inventory. JSON output uses `format: "r2flutter-recovered-sbom"` and
-`complete: false`; package versions are usually `null` unless explicit packaged
-metadata such as `pubspec.lock`, `.dart_tool/package_config.json`, or framework
-`Info.plist` survived in the input bundle.
-
-Dump actions honor the global format modifiers:
-
-```bash
-bin/r2flutter -i test/bins/ios/Runner.app
-bin/r2flutter -j -l 16 -i test/bins/ios/Runner.app
-bin/r2flutter -r -l 16 -i test/bins/ios/Runner.app
-bin/r2flutter -jS test/bins/ios/Runner.app
-bin/r2flutter -HHH -l 36 test/bins/android/mafia/libapp.so
-bin/r2flutter -O pp+0x68 test/bins/android/mafia/libapp.so
-bin/r2flutter -qrz test/bins/ios/Runner.app
-bin/r2flutter -rz test/bins/ios/Runner.app
-bin/r2flutter -rzz test/bins/ios/Runner.app
+```sh
+bin/r2flutter -H path/to/libapp.so
 ```

-## radare2 Plugin
+Then try a small, practical extraction:

-`make user-install` installs the core plugin command as `r2flutter`. Inside r2,
-the same modifiers apply to dump actions:
+```sh
+# Recovered Dart function entrypoints and names
+bin/r2flutter -f path/to/libapp.so

-```text
-r2flutter -A       analyze and apply flags/comments
-r2flutter -AA      analyze with field extraction enabled
-r2flutter -AAA     run Dart-aware code analysis and recover refs/comments
-r2flutter -C       apply Dart classes, fields, methods and types
-r2flutter -D 3.8.1  override Dart snapshot profile for analysis
-r2flutter -jS      print recovered components/SBOM as JSON
-r2flutter -r -p    map a synthetic ObjectPool and set anal.gp/x27
+# A compact JSON header, useful for scripts
+bin/r2flutter -jH path/to/libapp.so
+
+# The first 20 instruction-table entries
+bin/r2flutter -l 20 -i path/to/libapp.so
 ```

-Plugin config keys:
+Directory and bundle inputs work too. For example, pass an Android directory
+containing `libapp.so`, or an iOS `Runner.app` bundle directly.

- `r2flutter.mapfile`: Flutter obfuscation map JSON path
- `r2flutter.namepool`: enable heuristic name-pool fallback
- `r2flutter.profile`: override Dart profile by snapshot hash or Dart version
+After `make user-install`, open the same binary in radare2 and apply the Dart
+metadata to the analysis session:

-## Dependencies
+```sh
+r2 -q path/to/libapp.so
+> r2flutter -AAA
+> afl~method
+```

- radare2 (with development headers)
- pkg-config
+`-AAA` is the Dart-aware analysis pass. For a concise list of every action and
+output modifier, run `bin/r2flutter -h` or `r2flutter -h` inside radare2.

+# r2flutter — Analysis & Correction Roadmap
+
+Review of the library (`src/lib`), the r2 core plugin (`src/r2`), and the CLI
+(`src/tool`) for inconsistent, confusing, duplicated, or wrong assumptions when
+analyzing Flutter/Dart AOT snapshots on iOS and Android. Findings are verified
+against the source, the sample binaries in `test/bins`, real Dart SDK sources in
+`third_party/dart-sdk`, and a locally built Dart 3.12.2 AOT snapshot.
+
+Maintainer priorities: **1) robust Dart-VM version identification** ·
+**2) performance** · **3) iOS/Android correctness parity**.
+
+Items are ranked **P0** (do next) → **P3** (nice to have). Severity is implied by
+rank; each item states the concrete failure it causes.
+
+---
+
+## Status — what has been fixed (do not redo)
+
+| Commit | What landed |
+|--------|-------------|
+| `d387c0b` | Unknown-hash **fingerprinting** replaces the blind hardcoded "v3.9.2 defaults" (`dart_newest_profile()` auto-tracks the profile table). `-H` reports **`version_source`** (`exact-hash`/`override`/`fingerprint`/`unknown`) and labels guessed layouts `~<ver>+ (fingerprint)`. Report and decode paths now share the same layout (previously decode used a degenerate zeroed struct). Test: `header-fingerprint`. |
+| `2391781` | Explicit **3.7/3.8/3.10/3.11/3.12 CID + layout profiles** (parsed from each release's real `class_id.h`). Also **verified**: the floored tables were already byte-for-byte correct for *every* release 2.10.0–3.12.1, so no CID value changed — the rows are explicit coverage + a regression anchor. |
+| `cd6b655` | Discovery hardening: removed the **bogus instruction-blob classification** (only data snapshots carry magic `0xf5f5dcdc`; a stray hit could poison `iso_instr`); symbol-derived addresses are no longer clobbered by scan guesses; `vaddr==0` duplicates can't erase a good address; magic hits deduped; Mach-O segments skipped. |
+| `0716a95` | **Structural instruction-image location** for symbol-less Mach-O: `vm_instr` = first executable section, `iso_instr = align_up(vm_instr + ImageSize, 64)` from the Dart Image header, with cross-checks that fall back to `0` rather than emit junk. Verified on stripped Runner (`0x4000`/`0xe700`, full 7671 IT entries) and AuthPass (`0x5a80`/`0xfdc0`). The `discovery-stripped-ios` test clones the mapped thin slice with `o:`, clears symbol/export metadata with `wv4`, and reloads it with `ooi`. |
+| `d11ebc3` | **P0.1**: `modern_get_fill_spec`'s fallback `rules[]` is keyed by `DartCidKind` and resolved through a per-layout `by_kind[]` table built once in `modern_cid_cache_init`, instead of literal 3.6-era CIDs. Fixes a whole-block off-by-one on 3.2–3.5 layouts (36 CIDs from `SENTINEL` upward got the neighbouring class's ref/scalar layout) and `MonomorphicSmiableCall`/`UnlinkedCall` on 3.9+, where the two swapped places. Abstract classes that never form a cluster (`CallSiteData`, `AbstractType`, `TypedDataBase`) no longer claim a spec. |
+| `33bb19b` | **P2.5**: one shared cluster walker (`ModernWalk`) replaces the five hand-rolled tag→cid→alloc→fill loops. Consumers register readers in a `DartCidKind`-keyed table and the walker skips every class they don't claim, so tag decoding, alloc/fill skipping, `start_ref` bookkeeping and the inline-string decision each exist **once** (were 4–5× each). `modern_walk_fill_recorded` serves the resolver, which reads each cluster from its own recorded offset. Verified behaviour-preserving: output byte-identical on 5 samples × 21 actions. |
+| `e9fa905` | **Part of P0.2**: the read-only-data rule (`modern_walk_is_rodata`) — the six classes Dart moves into the data image when pointer compression is off (exactly `Serializer::ReadOnlyObjectType`) now correctly emit no fill records. Inert until the gate opens; see P0.2 for what still blocks it. |
+| `897a98d` | **P1.1**: one `dart_cid_from_tags` helper now decodes `CID_INT32`, `CID_SHIFT1`, and `OBJECT_HEADER` tags for object inspection, modern and legacy cluster walks, data-image scanners, and InstructionTable discovery. This removes the duplicate decoders and fixes `CID_INT32` being treated as `OBJECT_HEADER` in two paths. |
+| `833f89a` | **P2.1**: deleted the legacy cluster walker — `deserialize_clusters`, `decode_class_cluster`, `decode_function_cluster`, `resolve_names`, the `DartClass`/`DartPoolFunction` types and the `DartCtx.classes`/`.functions` fields that only it wrote (244 lines). It had been running on every `-f`/`-A` alongside the modern scanner while contributing nothing: verified before removal by stubbing it out (50/50 outputs identical), and after by diffing 95 sample×action outputs against the previous commit. `decode_string_cluster`/`skip_generic_cluster`/`free_dart_string` stay — the legacy **class** parser in `dart_pool_classes.c` still uses them for CID_SHIFT1 samples. |
+| `f10d30d` | **P2.2**: the fake `kXxxCid` enum is gone. Only 3 of its 28 values (`Class`, `PatchClass`, `Function`) matched any real Dart release, so the legacy class parser decoded Class/Function clusters and silently skipped String/Array/Type/Mint/Double — the ones it needed for names. Its `switch` is now an `if` chain over `LegacyClusterCids`, resolved per layout via `dart_cid_get`. The two sites that fell back to a *fabricated* id when resolution failed (`dart_pool_data_image.c`, `dart_pool_it.c`) now fail closed, and a third raw `kFieldCid` comparison was resolved the same way. `builtin_type_name` keeps working on `Type.type_class_id` — a class id packed in the type flags, not a ref despite the field name — but against real ids. The `ti->kind` discriminator, which was never a snapshot id, became `DartTypeKind`. |
+| `f10d30d` | **Perf, found via P2.2**: `cid_table_for_layout` resolved the CID table by comparing version *strings* against every row on **every** `dart_cid_get` call, and that call sits per-object on some paths. A one-entry memo keyed on the layout pointer makes it a pointer compare. Synthetic `-x` 4862 → **37 ms** (131×), mafia `-f` 1008 → 550 ms, mafia `-c` 756 → 312 ms. Output unchanged on all 95 comparisons. This was already the dominant cost *before* P2.2 — more evidence for the P3.1 note that the double cluster walk was the wrong suspect. |
+| `251bec7` | **Initial `--dump-xrefs`**: real-binary `-x` tests (`xrefs-android`, `xrefs-ios`) land, so the ObjectPool-use scanner is no longer covered only by the synthetic blob. |
+| `25dc49e` | **P3.5 + two `-x` correctness bugs**: `collect_pool_uses_from_entry` read JSON keys `pdj` does not emit. `offset` (real key: `addr`) always returned 0, so *every* pool use fell back to `entry->address` — the reported address was the function start, never the referencing instruction. `opstr` (real keys: `disasm`/`opcode`) was always NULL, making two of the three parser calls duplicates. The fixed 96-op window also ran past short functions (median Dart function is 28 instructions) into their neighbours; it is now bounded by the next entry's address. After the fix 100% of pool uses lie inside the function they are attributed to (before, 100% sat at a function start, which is why the attribution check could not fail). mafia `-x` 7783 → 4738 ms. Also hardens the `dart_cid_get` memo to key on a copy of the version text, not the (freeable) layout pointer. |
+| `334c97b` | **P2.3**: `cid_table_for_layout`'s fallback for a layout with no usable version now goes through `dart_newest_profile()` instead of the literal `"3.9.2"`, so it agrees with the baseline the version fingerprinter picks for an unknown hash. Verified a no-op today (the two tables have zero differing CIDs); it stops being one the moment a release shifts the numbering. |
+| `540efcf` | **P0.2 largely landed — the modern gate is now open.** `dart_modern_is_supported_snapshot` accepts `cws == 8` **and** `CID_SHIFT1`, not just `cws == 4` / OBJECT_HEADER. The fill desync that blocked this (the roadmap's cluster-12 failure on `hello.aot`) is resolved by `modern_skip_fill_instance` (version-dependent instance fill shape) and `modern_load_rodata_strings`, which reads the six RO-data string classes from the data image where uncompressed builds put them. **Result:** iOS Runner (3.4.3) recovers **6389 method names** where it emitted `func.<addr>` placeholders before; `hello.aot` (3.11.5) recovers 1130/1325. Tests `dump-funcs-ios-runner`/`-authpass`/`dump-it-ios-runner` updated to assert real names. **Still gated:** class/field extraction (`modern_can_extract_classes` keeps `cws == 4`), so `-c` on cws=8 still shows the weak `size=0` fallback — see the trimmed P0.2. |
+| `b6ea0b8` | **Synthetic fixture reconciled** with the varint-tag switch. `6a7e01b` correctly made the legacy class parser read cluster tags as varints (Dart writes them with `Read<uint32_t>`, a varint), which broke `bins/synthetic/field_snapshot.bin` — it stores raw LE u32 tags. Rather than re-encode the blob, the parser branches on `synthetic_legacy_parse`: raw u32 for the fixture, varint for real snapshots. All tests green again. The fixture still has no generator (see P4). |
+| `02efb30` | **String comments in `-AAA` disasm**: `PP+N` ObjectPool loads that resolve to a string now emit a `; dart: string "…"` comment at the referencing instruction. New test `analysis-string-comments`. |
+| `2db2a74` | **`-AAA` PP-string comments work on iOS.** A new direct resolver (`dart_modern_collect_direct_object_pool_string_refs`) resolves ObjectPool slots to string literals straight from the cluster graph, so `flutter_analysis.c` can annotate loads without a disasm round-trip. New test `analysis-string-comments-ios` asserts an `https` string comment on Runner. (Does **not** touch `-x`, which still round-trips through `pdj` — see the P3.1 note.) |
+| `bea45d8` | **Public API rename sweep**: `dart_modern_is_supported_snapshot`→`modern_supported`, `dart_ctx_effective_version/_hash`→`dart_ctx_version/_hash`, `dart_pool_enumerate`→`dart_pool_scan`, `dart_pool_dump_pp`→`dump_pool`, `dart_pool_extract_object_pool_strings`→`extract_pool_strings`, `dart_pool_dump_entrypoint`→`dump_entry`. No behaviour change. |
+| `43671cf` / `ef2fd32` / `791547c` | Test-only (authpass tutorial uses pure r2 commands; extras/analysis output) and README. No source behaviour change. |
+| *(uncommitted)* | **P0.2 second half — class/field extraction on `cws == 8`.** Two changes: `modern_extract_classes` now calls `modern_load_rodata_strings` after the cluster walk (the string classes live in the RO-data image on uncompressed builds, so their names were unresolved — every class came out `class_NNNN size=…`), and `modern_can_extract_classes` drops the `cws == 4` gate. The fill readers already decoded varints and scaled by `compressed_word_size`, so no reader change was needed. **Result** (OBJECT_HEADER cws=8): `hello.aot` 480/501 classes with real names+sizes+fields+methods (was 0), Runner 2233/2254 (was 0). cws=4 byte-identical (mafia unchanged). Graceful fallback preserved where the modern walk can't run: 2.18.2 (`android/first`) still desyncs in fill and AuthPass is `CID_SHIFT1` (class gate still requires OBJECT_HEADER) — both byte-identical to before. Goldens `classes-ios`/`types-ios`/`xrefs-ios` regenerated to the real output. |
+
+Corrections to earlier assumptions, worth remembering:
+- **The CID tables are not the problem.** Flooring is exactly correct 2.10→3.12,
+  verified against SDK sources. Only a *future* CID shift needs action, and the
+  generator adds a profile automatically when one appears.
+- **The `kDart*` snapshot symbols survive `strip`** — they are external/global and
+  load-bearing (the engine resolves them at runtime). Symbol-less iOS is an edge
+  case (obfuscators/repackagers), not the norm.
+- **The VM snapshot's canonical string cluster carries no canonical-set table**,
+  unlike the isolate's. Measured on `android/mafia`: skipping one there consumes
+  the next cluster's bytes and desynchronises the whole walk. This contradicts
+  the SDK, where `StringDeserializationCluster::ReadAlloc` always calls
+  `BuildCanonicalSetFromLayout` and both snapshots are read with
+  `is_non_root_unit=false`. Unexplained; `modern_vm_strings_alloc` encodes the
+  measured behaviour. Worth revisiting — it may mean the VM cluster range is
+  being located slightly wrong and the strings we recover are a happy accident.
+
+---
+
+## The finding that reshaped priorities — now largely acted on
+
+Historically **only 1 of 5 sample binaries** reached the "modern" (good) cluster
+decoder, because `dart_modern_is_supported_snapshot()` gated on
+`tag_style == OBJECT_HEADER && cws == 4`. `540efcf` opened that gate:
+
+| Sample | Dart | tag_style | cws | modern **name** path | modern **class/field** path |
+|--------|------|-----------|-----|-----------------|-----------------|
+| `android/mafia` | 3.9.2 | OBJECT_HEADER | 4 | **yes** | **yes** |
+| `android/first` | 2.18.2 | OBJECT_HEADER | 8 | **yes** | no — fill desync (see below) |
+| `ios/Runner.app` | 3.4.3 | OBJECT_HEADER | 8 | **yes** | **yes** (2233/2254) |
+| `ios/AuthPass.app` | 3.2.5 | CID_SHIFT1 | 8 | **yes** | no — class gate is OBJECT_HEADER-only |
+| `macos/hello.aot` | 3.11.5 | OBJECT_HEADER | 8 | **yes** | **yes** (480/501) |
+
+Name recovery runs on all five; class/field extraction now runs on every
+**OBJECT_HEADER** sample regardless of pointer width. Two hold-outs remain, both
+falling back gracefully (byte-identical to the old string-scan output):
+- **`android/first` (2.18.2)**: the modern fill walk desyncs at cluster 0
+  (`cid=92`) — a genuinely version-dependent fill shape in a pre-3.0 release, the
+  same class of problem P0.1 addressed for CIDs but for fill *layout*. This is the
+  only remaining fill-desync case in the corpus.
+- **`ios/AuthPass.app` (3.2.5, CID_SHIFT1)**: `modern_can_extract_classes` still
+  requires OBJECT_HEADER. The name path handles CID_SHIFT1; extending class
+  extraction to it is untried.
+
+---
+
+## P0 — correctness bugs with no test coverage
+
+### P0.2 (done for OBJECT_HEADER; two edge cases left)
+Class/field extraction on `cws == 8` **landed** (see status table): the gate
+dropped and `modern_load_rodata_strings` now runs on the class path. `hello.aot`
+and Runner recover real classes, fields and methods. Two follow-ups remain, both
+lower-value than the main win and both currently falling back cleanly:
+
+1. **2.18.2 fill desync** (`android/first`). The modern walk fails at cluster 0
+   (`cid=92`, an `Array`/string cluster in that era). Some pre-3.0 fill shape
+   differs from `rules[]`. To fix: bisect the first divergent cluster by diffing
+   per-class `ReadFill` between an old SDK and current (`third_party` has both),
+   using byte-per-object as the oracle, then make the affected rule version-aware
+   — same method the roadmap sketched for the (now-resolved) cluster-12 case.
+   Guard rails: `-c` must stay byte-identical on the working samples.
+2. **CID_SHIFT1 class extraction** (`ios/AuthPass.app`, 3.2.5).
+   `modern_can_extract_classes` requires OBJECT_HEADER; the name path already
+   handles CID_SHIFT1, so the cluster walk works — the untested part is whether
+   the class *fill* reader is correct under the shifted tag encoding. Try opening
+   it and check AuthPass `-c` against a known class list.
+
+### P0.3 Test corpus does not cover the decoders we ship
+Progress: iOS **name** recovery on cws=8 is now asserted
+(`dump-funcs-ios-runner`/`-authpass`, `dump-it-ios-runner`), and `-x` has
+real-binary coverage (`xrefs-android`/`-ios`). Remaining gaps:
+- a **Dart 3.4/3.5-era compressed-pointer** app (P0.1 is fixed but still has no
+  end-to-end regression test; it was verified only by resolving `rules[]` against
+  each layout in isolation);
+- cws=8 class/field extraction is now covered on both paths: iOS (`classes-ios`,
+  `types-ios` on Runner) and macOS/standalone (`dump-classes-macos` on
+  `hello.aot`, added alongside this note). The macOS golden is a real regression
+  anchor — reverting the `cws==8` gate fails all six of its assertions;
+- more **iOS** binaries generally, ideally real obfuscated/stripped release
+  `App`s (also broadens the `0716a95` structural path, per `COMMIT2.md`);
+- a **32-bit ARM** app if one can be found (validates P1.2).
+The remaining gaps (3.4/3.5-era compressed, obfuscated iOS, 32-bit) all need
+apps **collected externally** — the installed Dart SDK is 3.12.2, so a locally
+built AOT would exercise the modern decoder but *not* the old CID layout P0.1
+corrected, which is the one that still lacks an end-to-end test.
+
+---
+
+## P1 — correctness, lower prevalence or already-guarded
+
+### P1.2 Hardcoded 8-byte target word / arm64 assumptions
+- `modern_target_word_size()` (`dart_pool_modern.c:1196-1199`) **ignores `ctx` and
+  returns 8** — it takes `ctx` only to `(void)` it. All ObjectPool `pp_offset`
+  math (`:1201-1208`) and the synthetic-PP builder (`:2243-2262`) are wrong on
+  32-bit ARM, so `PP+N` lookups resolve to the wrong entry.
+- Entry-point stride hardcodes `*4` (`dart_pool_clusters.c:164`,
+  `dart_pool_classes.c:170`, `dart_pool_it.c:349,399`).
+- `-AAA` (`src/r2/flutter_analysis.c:104-129`) is entirely arm64 (PP=`x27`,
+  `x15/x29`, AAPCS64 clobber) with **no arch guard**; on arm32/x64 it emits wrong
+  PP annotations instead of bailing. Neither frontend checks `asm.arch`/`bits`.
+  **Fix:** gate on arch, derive the PP register, or refuse with a clear message.
+
+### P1.3 Plugin/CLI frontend drift (AGENTS.md violations)
+Two hand-maintained parsers: CLI getopt (`main.c:118`) vs plugin
+(`core_flutter.c:192+`).
+- **`-r` is missing in the plugin** (it only has `-*`), directly violating
+  AGENTS.md ("-q, -j and -r flags are modifiers"). `r2flutter -f -r` errors.
+- Plugin **silently no-ops under `r2 -n`** (`dart_app_new_from_core` returns NULL
+  via `R_UNWRAP4(core,bin,cur,file)`), so `-f/-A/-R` do nothing while `-H/-z/-i`
+  work — and `r2 -n` is the workflow AGENTS.md recommends.
+- CLI help advertises `[jr*]`/`-c*` but `*` is not in the getopt string.
+- Plugin help omits `-q` and `-f <N>`; `-C` is plugin-only; `-E` is CLI-only;
+  `-f <N>` grammar differs (CLI treats the number as the path).
+**Fix:** one shared parser/dispatch in the library so the modifier contract holds
+once. Cheap, visible, and unblocks consistent `-q/-j/-r` everywhere.
+
+### P1.4 iOS `LC_NOTE` (`__dart_app_snap`) container is CLI-only
+`main.c:84-97` extracts the embedded inner Mach-O; the plugin has no equivalent,
+so `r2flutter -H` inside r2 analyses the outer VM shell and fails, and
+`dctx.container_*` stays empty. **Fix:** move detection/extraction into the
+library so both frontends share it.
+
+### P1.5 Single-data-snapshot aliasing
+`pick_vm_iso_by_size` (`dart_pool_discovery.c:25-49`) with one snapshot assigns
+the same address to both `vm_data` and `iso_data` (visible on the synthetic bin:
+both `0x4`), so one is parsed as the other. The `sbom-synthetic` golden currently
+*encodes* this, so fixing it means deciding the right semantics (probably: lone
+snapshot is the isolate, leave `vm_data = 0`) and updating that test.
+
+---
+
+## P2 — duplication, dead code, structural debt
+
+### P2.4 CID/layout data still lives in three places
+`offsets.json` (source of truth, generated from SDK), `dart_cid.c` `cid_tables[]`
+(generated ✔), and `dart_offsets.h` `dart_hash_entries[]` — which only carries
+`hash → compressed_word_size`, a value already derivable from the profile and then
+overridden by the feature flags anyway (cws is decided three times, flags win).
+**Fix:** drop the hash→cws table or derive it.
+
+### P2.6 `data_image_base` recomputed in ≥3 places with a magic-16 fallback
+`dart_object.c:304-305`, `dart_pool_classes.c:1646-1655`, plus IT callers each do
+`snapshot + align_up(total_len, layout->max_alignment ?: 16)`. Extract one helper
+and confirm alignment is genuinely derived (it can be raised to 64) rather than
+silently defaulted.
+
+### P2.7 `-x`/`-z` special-case in both frontends (partly overtaken)
+`core_flutter.c` (`case 'x'`) and `main.c` set `string_refs = true` for *any*
+`-x`. The dispatch is now live (`case 'x' → dart_pool_dump_xrefs`), so the
+"dead branch" framing no longer holds — but the unconditional `string_refs`
+plus the `if (cmd->action != 'z')` guard still reads as accidental coupling
+between `-x` and `-z`. Re-audit against current line numbers before acting;
+lower priority than when first written.
+
+---
+
+## P3 — performance
+
+Read caching (`read_mem`, `dart_pool_snapshot.c:10-44`) already turns per-byte
+varint reads into a 1 MB sliding window. Remaining hotspots, largest first:
+
+### P3.1 Redundant full passes over the same regions
+A single `-f`/`-A` walks the cluster stream twice and the data image 2–3 times.
+
+**This was claimed to be the biggest perf win; measured, it is not.** Removing
+the whole legacy cluster walk changes runtime by ~1%, inside noise (mafia `-f`
+993 → 1005 ms; AuthPass `-f` 616 → 618 ms) — it bails out early rather than
+re-walking the stream.
+
+The real cost was elsewhere, and profiling found it: `dart_cid_get` re-resolved
+the CID table by version-string comparison on every call (see the status table).
+Memoising it took mafia `-f` from 1008 → 550 ms and the synthetic `-x` from 4862
+→ 37 ms — far more than P2.1 could ever have given. **Profile before spending
+time here.**
+
+`-x` was the next slowest; `25dc49e` fixed its correctness bugs and the window
+bound cut mafia `-x` 7783 → 4738 ms. The `pdj` JSON round-trip is now gone too
+(*uncommitted*): `collect_pool_uses_from_entry` decodes each instruction with
+`r_core_anal_op` and feeds `op->mnemonic` to the existing operand parsers — the
+same disassembly text, minus the JSON build/parse, matching the `-AAA` path in
+`flutter_analysis.c`. Output byte-identical on all 5 samples; mafia `-x`
+6052 → 3842 ms (~1.6×). AuthPass gains less (12776 → 11398 ms) — it spends most
+of its `-x` time in name resolution, not disasm. A full structured-operand
+rewrite (reading `RAnalValue` instead of `op->mnemonic` text) could skip capstone
+text rendering too, but arm64 operand modelling is unreliable enough that it
+would need per-encoding output diffing — not worth the risk for the remainder.
+
+**The 4096-entry scan cap is justified, not a bug — measured.** Removing it
+(scanning all 37258 IT entries) takes mafia `-x` from ~3.8 s to **55.8 s**; the
+per-instruction disasm dominates and there is no cheap way around it. The real
+wart is that `-l` conflates two limits: the output-line cap (`append_xref_info`)
+*and* the pool-use entry-scan cap (`collect_pool_uses`, default 4096 when no
+`-l`). Passing `-l 100` to trim output also silently narrows the scan to 100
+entries. Untangling them (a separate scan-depth control) belongs with the
+frontend-parser work (P1.3), not here.
+
+### P3.2 Brute-force InstructionTable header search
+`dart_pool_it.c:233-330` probes `{16,0,8,12} × delta -64..64 step 4`, then scans
+the whole data image every 16 bytes (`:209-231`), then a third linear scan
+`+0x40..+0x40000 step 8` (`:289-320`); `decode_pool_and_emit` additionally retries
+`dart_it_emit_varint` across `delta -64..64`. O(image) per lookup because the
+header location isn't derived. **Fix:** compute it from the layout — the Image
+header format is now understood (see `COMMIT2.md`: word0 `ImageSize`, word1
+`InstructionsSectionOffset`, 64-byte header), which should make the IT header
+directly addressable.
+
+### P3.3 Per-value snapshot-header re-parse
+`dart_object.c:296-312` calls `dart_snapshot_header_read(ctx, ctx->iso_data, …)`
+for *every* scalar value decode just to recompute `data_base`. Cache on the ctx.
+
+### P3.4 Read-cache tail cliff + forward-only thrash
+The 1 MB refill (`:37`) needs the whole range readable, so the last <1 MB of each
+section degrades to one syscall per byte; the window is forward-only, so name
+resolution alternating between the cluster stream and the string heap refills
+repeatedly. Consider a small multi-window/LRU cache and a short-read-tolerant refill.
+
+---
+
+## P4 — test quality (beyond the corpus gaps in P0.3)
+
+- **The synthetic fixture has no generator and is fragile.** `bins/synthetic/field_snapshot.bin`
+  is a hand-authored blob. It has already forced two special cases as the parser
+  was corrected: P2.2 had to renumber its cluster tags to real CIDs, and `b6ea0b8`
+  had to branch the tag reader on `synthetic_legacy_parse` because it stores raw
+  LE u32 tags while real snapshots use varints. Every future layout/encoding fix
+  risks a third. **Write a generator** so the fixture tracks the parser instead of
+  pinning obsolete conventions; the `synthetic_legacy_parse` branch could then go.
+- **Obfuscation-map tests are tautological**: `test/db/cmd/obf-map`,
+  `test/custom/obf-funcs-ios.json`, `obf-it-android.json` load a map whose keys
+  match nothing in the sample, so output is identical to the no-`-m` run. They
+  prove loading doesn't crash, never that renaming works. Add a fixture whose
+  keys actually occur.
+- `analyze-aaa-android.json` only greps `"Flutter analysis:"` — passes even if
+  nothing is recovered. Assert a recovered count/name.
+- Header tests pin entire JSON blobs incl. full CID tables: deterministic but
+  brittle (one new field broke ~10 tests during `d387c0b`). Consider
+  field-subset assertions like the `test/custom` specs already use.
+- Missing behaviours: plugin `-r`, plugin under `r2 -n`, gapped-layout structural
+  discovery (macOS, see `COMMIT2.md`), stripped **ELF**.
+- Directory-form input only recognises Android `libapp.so` / iOS
+  `App.framework/App` (`main.c:62-74`); `-H <dir-with-hello.aot>` errors "does
+  not exist". Broaden the resolver or document it.
+
+---
+
+## Suggested execution order
+
+1. **P1.3** — shared frontend parser (fixes the `-r`/`r2 -n` AGENTS.md
+   violations). While there, untangle `-l` for `-x`: give the pool-use scan its
+   own depth control instead of reusing the output-line limit (see P3.1).
+2. **P0.2 edge cases** — the 2.18.2 fill desync and CID_SHIFT1 class extraction
+   (both above). Smaller than the main win; do only if those eras matter.
+3. **P0.3** — a 3.4/3.5-era compressed sample for the still-untested P0.1 fix
+   (needs an externally-collected app; the local SDK is 3.12.2).
+4. **P1.2** — arch gating.
+5. **Write a synthetic-fixture generator** (see P4) so parser fixes stop needing
+   blob special-cases.
+6. **P3.2** — now a *lower* suspect than it looked; it never showed up in the
+   `-x` profile. Remaining P2 cleanups and test hardening.
+
+Done since last revision: P0.2 name+class paths (`540efcf`, `f85bd3b`), the
+macOS class regression test (`75ad39a`), and the `-x` `r_anal_op` rewrite
+(uncommitted).
+
+`COMMIT2.md` tracks the narrower follow-ups left over from the discovery work
+(gapped layouts, more iOS fixtures, stripped ELF, P1.5 semantics).

+# r2flutter binary release
+
+This package contains:
+
+* `bin/r2flutter` — the standalone command line tool
+* `plugins/core_flutter.{so,dylib,dll}` — the radare2 core plugin
+
+## Installing
+
+Copy the tool anywhere in your `$PATH` and drop the plugin into the radare2
+plugin directory reported by r2:
+
+```sh
+r2 -H R2_USER_PLUGINS   # per user, no root needed
+r2 -H R2_LIBR_PLUGINS   # system wide
+```
+
+For example:
+
+```sh
+mkdir -p "$(r2 -H R2_USER_PLUGINS)"
+cp plugins/core_flutter.* "$(r2 -H R2_USER_PLUGINS)"
+cp bin/r2flutter /usr/local/bin
+```
+
+On Windows the plugin directory is usually `%HOMEPATH%\.local\share\radare2\plugins`.
+
+## Checking the installation
+
+```sh
+r2 -qc 'Lc~r2flutter' --
+r2flutter -V
+```
+
+The plugin must match the radare2 version it was built against, otherwise r2
+refuses to load it.

+# AuthPass.app Dart AOT TLS tutorial
+
+This tutorial uses the iOS fixture:
+
+```text
+test/bins/ios/AuthPass.app
+```
+
+Run commands from the repository root. The Dart AOT image is not the top-level
+`Runner` executable; it is:
+
+```sh
+IOS_BUNDLE=test/bins/ios/AuthPass.app
+IOS_APP="$IOS_BUNDLE/Frameworks/App.framework/App"
+```
+
+Rebuild the tools and plugin before following the r2 steps:
+
+```sh
+make
+make r2
+make user-install
+```
+
+## Challenge 1: recover Dart AOT method names and map the TLS handshake path
+
+Start by verifying that r2flutter recognizes the snapshot:
+
+```sh
+bin/r2flutter -j -H "$IOS_BUNDLE"
+```
+
+Expected important values:
+
+```text
+"dart_version":"3.2.5"
+"hash":"f71c76320d35b65f1164dbaa6d95fe09"
+"it_len":37092
+"tag_style":"CID_SHIFT1"
+```
+
+Dump recovered functions and resolve the TLS methods by semantic name. Do not
+hardcode the private suffix; AuthPass uses `14069316`, but that value changes
+between snapshots.
+
+```sh
+FUNCS=$(mktemp)
+bin/r2flutter -q -f "$IOS_BUNDLE" > "$FUNCS"
+
+BAD_CERT_ADDR=$(awk '/method\._RawSecureSocket_.*\._onBadCertificateWrapper_/ { print $1; exit }' "$FUNCS")
+REGISTER_ADDR=$(awk '/method\._SecureFilterImpl_.*\.registerBadCertificateCallback$/ { print $1; exit }' "$FUNCS")
+REGISTER_IMPL_ADDR=$(awk '/method\._SecureFilterImpl_.*\._registerBadCertificateCallback_/ { print $1; exit }' "$FUNCS")
+HANDSHAKE_ADDR=$(awk '/method\._RawSecureSocket_.*\._secureHandshake_/ { print $1; exit }' "$FUNCS")
+MARK_TRUSTED_ADDR=$(awk '/method\._SecureFilterImpl_.*\._markAsTrusted_/ { print $1; exit }' "$FUNCS")
+
+printf 'wrapper=%s register=%s register_impl=%s handshake=%s mark=%s\n' \
+  "$BAD_CERT_ADDR" "$REGISTER_ADDR" "$REGISTER_IMPL_ADDR" "$HANDSHAKE_ADDR" "$MARK_TRUSTED_ADDR"
+rm -f "$FUNCS"
+```
+
+Expected output:
+
+```text
+wrapper=0x3199d4 register=0x3194ec register_impl=0x31954c handshake=0x31749c mark=0x31925c
+```
+
+Apply r2flutter flags in r2 and confirm that the same method flags exist:
+
+```sh
+r2 -q -e scr.color=0 -e bin.relocs.apply=true \
+  -c 'r2flutter -A' \
+  -c 'f~onBadCertificateWrapper' \
+  -c 'f~registerBadCertificateCallback' \
+  -c 'f~secureHandshake' \
+  -c q "$IOS_APP"
+```
+
+Expected method flags:
+
+```text
+0x003199d4 0 method._RawSecureSocket_14069316._onBadCertificateWrapper_14069316
+0x003194ec 0 method._SecureFilterImpl_14069316.registerBadCertificateCallback
+0x0031954c 0 method._SecureFilterImpl_14069316._registerBadCertificateCallback_14069316
+0x0031749c 0 method._RawSecureSocket_14069316._secureHandshake_14069316
+```
+
+Now disassemble the handshake:
+
+```sh
+r2 -q -e scr.color=0 -e bin.relocs.apply=true \
+  -c 'r2flutter -A' \
+  -c "s ${HANDSHAKE_ADDR:-0x31749c}" \
+  -c 'pd 104' \
+  -c q "$IOS_APP"
+```
+
+Useful lines:
+
+```asm
+0x003174e4  bl method._SecureFilterImpl_14069316.handshake
+0x00317514  bl method._RawSecureSocket_14069316._secureHandshake_14069316

+```
+
+The boolean constants are visible in this cluster:
+
+- `x22 + 0x20` is Dart `true`.
+- `x22 + 0x30` is Dart `false`.
+
+## Challenge 2: patch `_RawSecureSocket._onBadCertificateWrapper`
+
+Disassemble the wrapper:
+
+```sh
+r2 -q -e scr.color=0 -e bin.relocs.apply=true \
+  -c 'r2flutter -A' \
+  -c "s ${BAD_CERT_ADDR:-0x3199d4}" \
+  -c 'pd 24' \
+  -c q "$IOS_APP"
+```
+
+Important instructions:
+
+```asm
+0x003199d4  stp x29, x30, [x15, -0x10]!
+0x003199ec  ldr x0, [x29, 0x18]
+0x003199f0  ldur x1, [x0, 0x5f]
+0x003199f4  cmp x1, x22
+0x003199f8  b.eq 0x319a28
+0x00319a00  stp x16, x1, [x15]
+0x00319a0c  ldur x2, [x0, 0x37]
+0x00319a10  blr x2
+0x00319a1c  ret
+```
+
+AuthPass differs from the Android samples: on the normal path the wrapper
+returns the app-provided bad-certificate callback result unchanged. The bypass
+target is still the wrapper entry. Returning Dart `true` before the callback
+logic makes the certificate decision succeed.
+
+For this fixture, `rabin2 -S "$IOS_APP"` reports equal `__text` physical and
+virtual addresses:
+
+```sh
+rabin2 -S "$IOS_APP" | rg '__TEXT.__text'
+```
+
+Expected:
+
+```text
+0   0x00005a80  0x6f8bd0 0x00005a80  0x6f8bd0 -r-x 0x0   REGULAR  0.__TEXT.__text
+```
+
+That means the recovered method virtual address is also the raw file offset for
+this fixture. If this is not true for another Mach-O, translate with:
+
+```text
+section_paddr + (method_vaddr - section_vaddr)
+```
+
+Patch a copy first:
+
+```sh
+cp "$IOS_APP" "$IOS_APP.bak"
+
+r2 -q -w -n -e scr.color=0 \
+  -c "s ${BAD_CERT_ADDR:-0x3199d4}" \
+  -c 'wx c0820091c0035fd6' \
+  -c q "$IOS_APP"
+```
+
+Patch bytes:
+
+```text
+c0820091 c0035fd6
+```
+
+Decoded AArch64:
+
+```asm
+add x0, x22, 0x20
+ret
+```
+
+Verify:
+
+```sh
+r2 -q -n -a arm -b 64 -e scr.color=0 \
+  -c "s ${BAD_CERT_ADDR:-0x3199d4}" \
+  -c 'p8 8' \
+  -c 'pd 2' \
+  -c q "$IOS_APP"
+```
+
+Expected:
+
+```text
+c0820091c0035fd6
+add x0, x22, 0x20
+ret
+```
+
+Restore the fixture after testing:
+
+```sh
+cp "$IOS_APP.bak" "$IOS_APP"
+```
+
+You can also use the generic qjs helper on a copy:
+
+```sh
+TMP_APP=$(mktemp /tmp/r2flutter-authpass-app.XXXXXX)
+cp "$IOS_APP" "$TMP_APP"
+r2 -q -w -e bin.relocs.apply=true \
+  -i scripts/dart_cert_bypass.qjs \
+  "$TMP_APP"
+r2 -q -n -a arm -b 64 -e scr.color=0 \
+  -c 's 0x3199d4' \
+  -c 'p8 8' \
+  -c 'pd 2' \
+  -c q "$TMP_APP"
+rm -f "$TMP_APP"
+```
+
+The script resolves `method._RawSecureSocket_*._onBadCertificateWrapper_*`
+through r2flutter flags, translates the method address to a file offset using
+section metadata, and writes the same two AArch64 instructions. It expects the
+actual Dart image to be opened in r2: Android `libapp.so` or iOS
+`Frameworks/App.framework/App`.
+
+## Challenge 3: trace callback registration and direct xrefs
+
+Disassemble callback registration:
+
+```sh
+r2 -q -e scr.color=0 -e bin.relocs.apply=true \
+  -c 'r2flutter -A' \
+  -c "s ${REGISTER_ADDR:-0x3194ec}" \
+  -c 'pd 44' \
+  -c q "$IOS_APP"
+```
+
+Useful lines:
+
+```asm
+0x0031950c  stur x0, [x1, 0xf]
+0x00319530  bl method._SecureFilterImpl_14069316._registerBadCertificateCallback_14069316
+0x00319534  mov x0, x22
+0x00319540  ret
+```
+
+Run lightweight reference analysis and query the resolved TLS addresses:
+
+```sh
+r2 -q -e scr.color=0 -e bin.relocs.apply=true \
+  -c 'r2flutter -A' \
+  -c 'aar' \
+  -c "axt @ ${BAD_CERT_ADDR:-0x3199d4}" \
+  -c "axt @ ${REGISTER_ADDR:-0x3194ec}" \
+  -c "axt @ ${REGISTER_IMPL_ADDR:-0x31954c}" \
+  -c "axt @ ${HANDSHAKE_ADDR:-0x31749c}" \
+  -c q "$IOS_APP"
+```
+
+Observed direct xrefs:
+
+```text
+0x3199bc -> 0x3199d4  _RawSecureSocket._anon_closure -> _onBadCertificateWrapper
+0x316cd8 -> 0x3194ec  _RawSecureSocket constructor -> registerBadCertificateCallback
+0x319530 -> 0x31954c  registerBadCertificateCallback -> _registerBadCertificateCallback
+0x317028 -> 0x31749c  _RawSecureSocket constructor -> _secureHandshake
+0x317514 -> 0x31749c  _secureHandshake -> _secureHandshake
+0x3178b4 -> 0x31749c  _tryFilter -> _secureHandshake
+0x317e04 -> 0x31749c  _closeHandler -> _secureHandshake
+```
+
+The call into the app-provided certificate callback inside the wrapper is
+indirect (`blr x2`), so it is not expected to produce a stable direct `axt`
+target. The stable evidence is the callback registration, the wrapper body, the
+TLS method cluster, and the direct references to the wrapper.
+
+## Regression tests
+
+The tutorial workflow is covered by:
+
+```sh
+r2r -u test/db/cmd/authpass-r2-tutorial
+```
+
+The tests validate:
+
+- r2 plugin flag recovery for the AuthPass TLS methods.
+- wrapper and handshake disassembly landmarks.
+- direct xref/callsite sources without running full analysis in the test.
+- the generic qjs bypass script on a temporary copy.
+
+Patching the embedded iOS framework invalidates the bundle code signature. A
+real deployment requires re-signing with the appropriate identity/provisioning
+workflow.

+ * Patch Dart AOT RawSecureSocket bad-certificate wrappers in an opened r2 file.
+ *
+ * Usage:
+ *   r2 -w -e bin.relocs.apply=true -i scripts/dart_cert_bypass.qjs libapp.so
+ *   r2 -w -e bin.relocs.apply=true -i scripts/dart_cert_bypass.qjs Runner.app/Frameworks/App.framework/App
+ *
+ * The opened file must be the Dart AOT image itself, not an APK/IPA/bundle
+ * directory. Android usually uses libapp.so. iOS Flutter apps usually use
+ * Frameworks/App.framework/App.
+ *
+ * This script is intentionally suffix-agnostic: it resolves the
+ * method._RawSecureSocket_*._onBadCertificateWrapper_* flag produced by
+ * r2flutter, translates the method vaddr to a raw file offset, and writes:
+ *
+ *   add x0, x22, 0x20
+ *   ret
+ *
+ * Those bytes are AArch64-specific and return Dart true in the observed
+ * Android/iOS AOT snapshots.
