dabao1955	cd1df50a2a	Complete the xvmp IR virtualizer end to end and measure the de-virtualization chain on a real fixture ... The public xvmp tree ships a compiler half that was never compiled (no TU includes the virtualizer headers; on dev trees they do not build), a weak empty vm_exec stub, silent skips for unsupported IR, and a companion article describing an earlier prototype that is not in the tree. This change completes and measures the chain: - Completed toolchain, merged into all four omp branches of that tree: gated new-PM pass wiring (-mllvm -irobf-irvm, section .irvm), FORMAT v3 bytecode (8-byte aligned slots, explicit load/store widths, stable CC_ cast kinds, per-index GEP byte scales, branch condition = operand 0), a strong-symbol vm_exec interpreter with a 23-check unit suite, and a VMP.h user header. Virtualized vs native output identical at -O0/-O1/-O2 on all four branches. One branch's ungated IRVM call in Obfuscation::runOnModule (rewrote .irvm functions in plain native builds) removed; IRVM is strictly flag-gated. - Fixture measured end to end (fco+bcfobf+subobf+IRVM build): native-identical output; 17,961-step guest trace via VMP_TRACE; 24.6M-instruction host trace via a ptrace single-stepper; vm_handler_slice yields 95,184 segments / 18 unique signatures; the fla outer state machine separates as a shuttle class, round-boundary segments split the trajectory, positional alignment names every handler segment (59/59 in a round; counts match the guest histograms exactly), zero unmapped with --opcode-map. - Tooling hardening measured on the real fixture: opcode maps key by signature (first-block keys collide under a shared dispatch successor); apply_map keeps first-block keys as fallback, regression tests added. - Environment boundary recorded: frida stalker does not work in these containers (measured past the syscall layer: primitives pass, agent loads, zero denied syscalls; the failure is inside the injected agent's hook machinery), an outer ptrace tracer conflicts with frida spawn, and the ptrace stepper is the working host capture path. Design lesson: a pure virtualized call can still be LICM-hoisted by the compiling optimizer. Records: EXTENSION-sampling-crash.md SS5-SS6 (final-state rewrite), known-limitations.md, ete-diff-tracing.md SS5, vm_handler_slice.py header, capability matrix.	2026-10-16 14:45:03 +08:00
root	ab22b225ff	Hardware pass: hardware watchpoints, ETE differential tracing, kernel-side event injection ... Add the layer under the software tooling, in the repository's shape: what runs on a host is measured, and every device-bound or kernel-bound piece is a gated, labelled template. - scripts/hw_watch.py: arm64 hardware watchpoints/execution breakpoints. WCR/ BCR encoders with the 8-byte-window and alignment rules (unit-tested to the canonical 0x1FFD/0x3F05), a self-contained on-device ptrace helper that compiles clean as a static aarch64 ELF (observed: cross gcc 16.2), adb orchestration, and hit decoding to module+offset. The stealth ledger is stated three times on purpose: the ptrace route leaves TracerPid visible. - scripts/ete_capture.py: CoreSight ETE capture with the five gates (kernel era, coresight sysfs, cs_etm PMU, perf-with-CORESIGHT, permission), the perf/OpenCSD build recipe, and the per-thread record wrapper whose --control one-instruction run must pass before any real capture. - scripts/trace_diff.py: differential reduction of two execution traces into first-divergence / divergent regions / blocks-unique-to-each-side. Producer-agnostic: Stalker BLK logs (raw or run_probe-wrapped) and decoded cs_etm address streams alike, host-tested on synthetic flattened-dispatcher fixtures. - scripts/kernel_instrument_scaffold.py: KPM/LKM watchpoint + register-rewrite templates plus an honest userspace carrier; every kernel file carries a NOT COMPILED AND NOT LOADED banner that verify enforces, and the register-rewrite action is fenced as experimental in the template itself. - references/hardware-watchpoints.md, references/ete-diff-tracing.md, references/kernel-event-injection.md: the mechanism, the gates, the traps, and the composition recipes (watch the key buffer; diff two runs; flip the decision at the trap), with hand-offs instead of duplication. - Registration: 3 symptom rows (SKILL.md + routing mirror), 3 reference rows, 4 script rows, coverage/route-inventory/evidence rows, capability-matrix entries, known-limitations entry, eval case 4, README trees and coverage paragraphs in both languages, and three EXTENSION evidence records stating exactly what was measured on this host (encoders, compile, fixtures, generate/verify) and what was not (no watchpoint armed, no cs_etm stream, nothing kernel-side compiled or loaded anywhere). Hardware pass 2: SPE/BRBE crash forensics, address symbolization, VM de-virtualization Calibrated against the two public obfuscator implementations the user supplied (dpkg123/ollvm-aosp-toolchain: Hikari-family and Pluto-family flattening, the xvmp IR virtualizer at 63fec41f/9b7cf75e; fetched read-only into tools/_work/refs, git-ignored). Source facts observed, runtime inferred. - scripts/trace_addr2sym.py: runtime addresses -> symbol + static offset, zero-dependency ELF64 (PT_LOAD vaddr<->file-off conversion, .dynsym/.symtab, stripped section+off fallback). Host-verified against a real cross-compiled aarch64 .so with readelf as the independent cross-check, plus a hand-built minimal ELF covering vaddr!=offset; accepts hw_watch hits, trace mod+off keys, or raw address lists. Fixes on the way: --base int coercion, and nearest-below symbol semantics for PCs in inter-symbol gaps. - scripts/vm_handler_slice.py: slice an interpreter trace into handler segments (dispatcher detection = histogram top + predecessor diversity; the first 4x-margin rule refused the calibrated fixture itself and was replaced), signature clustering, open-tail handling, and the guest-opcode trajectory via an optional handler->opcode map. Calibrated against xvmp's documented shape: vm_exec(code,size,vm_args,num) stubs, boxed arguments observable before interpretation, 11 opcodes + 19 arithmetic sub-ops, const-materialization dispatch as a distinct segment. - references/hardware-sampling-and-crash.md: SPE (data flow without a known address; PC + data address per sample), BRBE (branch records when a crash stack cannot be trusted), the crash loop (tombstone -> branch records -> symbolize), and what each adds to the OLLVM/VMP routes. All documented-and-gated: no SPE sample or BRBE record was captured here. - Flattening-recipe corrections from source: Hikari keeps a frame-resident switchVar written through an indirect pointer with scramble32-permuted cases; Pluto stores switchVar/switchXor rolling-XOR so memory only ever holds noise -- hardware-watchpoints.md's state-variable recipe now distinguishes the families, and ete-diff-tracing.md carries the family table plus the xvmp shape. AntiDebugging injects raw svc inline asm with randomized fields, so byte signatures cannot survive it; semantic site-location can. - Registration: 3 symptom rows (untrustworthy crash stack; runtime addresses needing symbols; interpreter loop reading as noise), reference/script rows, coverage/evidence/capability-matrix entries, README trees in both languages, and EXTENSION-sampling-crash.md recording exactly what was measured (real .so symbolization, slicer fixtures, the slicer's self-found dispatcher-rule bug) and what was not (no SPE/BRBE capture, no hardened binary ever traced). Fix all PR #1 review findings by severity; un-entrench the tests that pinned them Major (device-breaking / wrong results): - hw_watch: match the arm64 user_hwdebug_state slot ABI (address register first, control second -- the swap armed nothing correctly) - hw_watch: every post-seize error path now clears slots and detaches; PTRACE_O_EXITKILL turned an analysis failure into a SIGKILL of the target - hw_watch: forward genuine target SIGTRAPs (raise/tgkill/int3); only ptrace event stops are consumed -- the reference's signal-preservation promise - hw_watch: run checks push/build/chmod and the helper's exit status; a dead capture is RESULT=blocked, never ok-no-hits - hw_watch: decode offsets from the module base, not each mapping's start - ete_capture: --control now requires the control record to DECODE (perf script event lines), the documented gate, not just a zero exit - ete_capture: -o before the -- workload separator in --cmd mode; all values shell-quoted into su -c; stale remote perf.data removed first; perf exit status checked (timeout's 124 is the normal window end) - kernel scaffold: --set-reg restricted to x0..x30; the rewrite is gated by its own breakpoint event so a watchpoint hit cannot run it; LKM pins the task (get/put_task_struct) across registration and calls the four-argument register_user_hw_breakpoint; --break rows initialize .addr/.len/.bp_type (there is no .pc member); --id validated against the module-id grammar - trace_addr2sym: exact module matching (path or basename, never substring); load bias aligned against the PT_LOAD (bias = start - (foff - p_offset) - p_vaddr); PCs outside the ELF span are refused instead of landing on the last symbol; --json stdout is a pure document (RESULT= in text mode only) - trace_diff: block keys need 0x or >=8 hex digits (PIDs/counts no longer parse); vm_handler_slice: dispatcher needs predecessor diversity, no frequency-margin fallback; both JSON outputs pure (check_commands' rule) Minor/nitpick: - capability-matrix + evidence-summary: trace reduction status ok->partial (no real-target producer ran it; the file's own definition of ok) - hardware-sampling-and-crash.md and the script examples carry --elf - kernel-event-injection.md no longer claims the callback's first statement is a filter (it prints unfiltered; the filter is a required change) - Elf64 caches symbol addresses for per-row bisect - docstring coverage of the touched surface: 16.67% -> 100% Tests: every json.loads workaround stripping RESULT= is gone; new regression tests cover the slot ABI, release-on-error, SIGTRAP forwarding, non-first mapping offsets, -o placement and su -c quoting, the control decode gate, x31/--id refusals, the guarded rewrite, outside-ELF PCs and bias math, short-token refusal and the dispatcher margin rule. The minimal-ELF fixture now packs a full 8-field Elf64_Phdr (its 7-field pack silently shifted p_memsz onto p_align). 739 passed; flake8/mypy and all five gates clean. Address the follow-up review on 0bd8dfe (6 findings) - ete_capture: two-layer quoting for the control-record, decode and cleanup commands -- shlex.quote spliced between literal single quotes broke out of su -c for any spaced output name; --seconds must be positive (timeout 0 disables the timer), refused before any adb check - kernel scaffold: --set-reg now refuses sp/pc as well (the template has no rewrite path for them; a generate that silently drops the action is the misleading kind of success); both templates arm with a sampling period (LKM via hw_breakpoint_init, KPM spells out sample_period=1) -- a zero period is a non-sampling event whose callback never fires: armed, silent - trace_addr2sym: contains_vaddr tests each PT_LOAD's loaded span instead of the whole-file extent; a PC in the unmapped gap between segments is refused rather than named after the nearest symbol below - trace_diff: a bare all-digit token is indistinguishable from a date or count, so block keys need 0x or a non-decimal hex digit; a date-only log stays refused as a capture failure Tests: two-layer quoting with a spaced control name, --seconds refusal, sp/pc in the rejection list, sampling-period assertions for both templates, a two-segment gap fixture, and a date-only parser case. 743 passed; flake8, mypy and all five gates clean.	2026-10-15 15:33:28 +08:00
inliver233	5aa4c97050	Merge PR #2 (dabao1955): expand the CI matrix, and finish the dcc.py declaration ... The PR diagnosed the same CI failure this branch had just fixed, from the other end, and two of its three changes are kept. .github/workflows/ci.yml KEPT. The matrix was ["3.11", "3.13"] while the frontmatter claims Python 3.9+; it is now 3.11-3.14. Both new versions were checked here before taking it: the gates and the full suite pass on 3.12 and 3.14. check_commands.py KEPT. dcc.py added to EXTERNAL_SCRIPTS. This branch reached the same conclusion structurally -- recognition by filename needs the gitignored tools/ tree to exist -- and the explicit entry is the better belt for the same braces, because it names the situation instead of inferring it. Both spellings are declared: the bare dcc.py the java2c record uses and the ./dcc.py this branch''s record uses. its new test KEPT, with one assertion corrected. It pinned workbench-after-cd when the workbench was present and xternal when it was not, so it asserted one mechanism at a time -- and would have failed on any machine with tools/ present once the declaration above exists, i.e. it was itself machine-dependent, which is the defect the test guards. It now asserts the property both mechanisms produce. Verified on the merged tree, in both shapes: with tools/ present, 619 passed / 158 skipped / 25 xfailed and all five gates exit 0; with tools/ hidden to imitate a clean checkout, 596 passed / 181 skipped / 25 xfailed and all five gates still exit 0. The second shape is the one CI runs, and it is the check that was missing when the previous commit was pushed.	2026-09-22 17:12:45 +08:00
inliver233	dd8057cfcb	Make the command gate machine-independent, and calibrate the budget fallback ... CI went red on `1dc1d9b` in both jobs while the identical command passed locally, and the reason is worth keeping: the checks depended on state that only exists on a developer's machine. check_commands.py -- the gate's verdict depended on a gitignored directory The previous commit's fix recognised a workbench script by matching its name against a walk of `tools/`. That tree is gitignored, so a clean checkout has none of it: `dcc.py` matched locally and skipped, and on CI nothing matched, it fell through to `missing-script`, and the gate reported drift for three quoted lines. A check whose verdict changes with a directory CI does not have is not a check. Two changes remove the dependency: * `qualified_basenames()` collects every `.py` the *document itself* writes with a path, so a bare name the document has already located elsewhere is a skip, computed from the text. * `./dcc.py` is a declared upstream entry point, checked before the workbench-name test. * a bare name after a `cd` that resolves nowhere is `after-cd-unresolved` -- unverifiable, which is not the same claim as broken, and is now reported as such instead of as drift. Verified by running the whole CI sequence against a tree with `tools/` hidden: five gates exit 0, the suite passes. That experiment is the one that should have been run before the first push. check_budget.py -- the measurement was installation-dependent The gate measures the always-loaded body in tokens, preferring `tiktoken` and falling back to `characters / N`. `N` had been guessed at 3.6 rather than calibrated, so a machine with tiktoken saw ~11.1k tokens and passed while a machine without it saw ~14.2k and warned -- and CI's 3.11 job is the one without it. `N` is now the measured 4.285 characters per token (47,629 chars -> 11,114 tokens on SKILL.md), both paths agree within one token, and `tests/unit/test_budget_measurement.py` forces both paths and asserts they do not straddle the budget. CI now installs `tiktoken` so the comparison exercises the real tokenizer instead of skipping. Also: two `.py` files are formatted for consistency, and the reconstruction record documents the CI-only failure, since "it passed on my machine" is the lesson rather than an aside. Gates: check_repo 0 problem, check_refs 0 dangling / 0 warning, check_routing coherent, check_budget 0 failure / 0 warning (both measurement paths), check_commands 154 checked / 0 drift, pytest 617 passed on 3.14 and 609 on 3.11.	2026-09-22 17:09:22 +08:00

inliver233	1dc1d9b707	Fix the command gate's blind spot, and make --json actually be JSON ... A reviewer reported seven drifting commands in the evidence record. Reproduced, the report split three ways, and the middle category was the useful one: the gate had been scoring them clean. Not reproducible, with the measurement: tests/run_tests.py -q runs. The wrapper forwards its arguments to pytest (`args = list(argv[1:]) or ["-q"]`), and documents that in its own usage. dcc.py already written as `cd tools/_work/bench/repos/dcc` followed by `python dcc.py ...` -- an external checkout, not a shipped script. Real, and fixed here: seven commands in two evidence records named a **workbench** script with no path at all (`analyze_pair.py`, `make_skeleton.py`, `ttd_attach.py`, `b2_measure.py`). The files exist under `tools/`, which .gitignore excludes, so a reader copying one from the repository root gets "No such file" -- and two of those documents wrote the correct path elsewhere, so they disagreed with themselves. **The actual defect was in `check_commands.py`, not in the seven lines.** `resolve_script()` tried the document's own directory first, so a bare `analyze_pair.py` inside `docs/tool-verification/` resolved to `tools/_work/bench/unpack/b3/analyze_pair.py` -- a real file -- and passed. Resolution now follows the order a reader would try (repository root, then the skill's scripts, then the document's own directory, which is what `../x.py` in a nested README legitimately means); a bare name that only resolves under `tools/` is `unqualified-workbench`; and that class counts as **drift, not as a skip**, because it is a one-token fix that a reader cannot run. The first attempt classified it as a low-confidence warning, which would have left all seven in place. One exception is honoured and pinned: a code block opening with `cd tools/_work/bench/repos/dcc` is telling the reader where to stand, so a bare `python dcc.py` after it is correct. `documented_commands()` now reports whether a `cd` preceded the command in the same block, and that case is skipped as `workbench-after-cd`. Two defects of this pass's own, found while fixing it: --json emitted the RESULT= token after the JSON document, so `--json | jq` failed with "Extra data". The token is gone from that path; the status is a field in the document, and the exit code carries the same meaning. The fix's own substitution left four literal backslashes before `$` in the two files it edited -- a character a reader would copy by mistake. Removed, and verified absent. `tests/integration/test_check_commands_gate.py` pins the resolution order, the drift classification, the `cd` exception, and a clean pass over the committed tree, so this cannot come back silently. Gates: check_commands 153 checked / 0 drift, check_repo 0 problem, check_refs 0 dangling / 0 warning, check_routing coherent, check_budget 0 failure / 0 warning, pytest 613 passed / 158 skipped / 25 xfailed.	2026-09-22 02:18:40 +08:00
inliver233	2beade67f2	Reconstruction pass: make the gates tell the truth, make the package self-contained, keep the one-hop symptom index ... An external audit of this repository landed on four structural findings, and this pass is the response to them. Everything below was re-measured on this tree before being acted on; two of the audit's claims needed a correction of my own, and both corrections are noted in place. **The gates were optimistic, and one of them did not read content at all.** doctor.py the capability table was hard-coded (`repack + sign = bool(java) and python`), so a machine with a JDK and no zipalign/apksigner was told it could re-sign; the script inventory was a hand-written list of 28 against 51 files on disk, omitting the nine most important scripts. It now scans the directory (`registered/checked = 52 / 52`, unjudgeable entries counted as `unknown`, never skipped) and resolves capability as a real requires-closure, reporting BLOCKED with the missing piece and an installable next step. Measured: the old doctor reports `[OK] repack + sign` on a JDK-only PATH where keytool, jarsigner, zipalign, apksigner and all eight smali jars are absent. The report is allowed to look bad; that is the point. check_commands.py (new) anchor checks prove a section exists, never that a command runs. This parses each script's argparse table with `ast` and checks every documented invocation against it. 146 commands / 41 interfaces, 0 drift. It caught `sig_probe.py --live --pkg`, which does not exist -- the reference had been wrong since it was written. check_routing.py (new) the symptom index now has one home (`SKILL.md`, because symptom -> file must stay one hop) and the inventory has another (`references/routing.md`). This gate proves the mirror agrees, that every reference file is named, and that every script is named. **so_constpatch.py was corrupting APKs it rebuilt.** The writer copied filename and timestamp onto a fresh ZipInfo and recompressed the whole archive: 435-entry real package, `extra` lost on 205 entries, `external_attr` rewritten on all 435, 132 untouched entries recompressed, and `resources.arsc` pushed to an unaligned offset. Android's own `zipalign -c -v 4` fails the old output and passes the new one; a 26-case fixture suite pins it, and `extractNativeLibs="false"` is now refused by default with a pointer at `repack.py`. Fixing it exposed the same defect in `repack.py`, where `^lib/[^/]+\.so$` cannot match `lib/arm64-v8a/*.so` -- so its alignment handling had never once fired on a real APK. **The package was not self-contained.** 59 references pointed at the repository root, which `npx skills add` does not install. They now converge on `references/evidence-summary.md` (capability, conclusion, strength, evidence that ships) plus `evidence/` with the machine-readable companions: 8 references remain and each is explicitly labelled "repository root, not shipped". A drill in which the new files were copied to an isolated directory and asked three questions answered all three. **SKILL.md: 572 lines / 15,733 tokens -> 398 lines / ~10,900 tokens**, without losing the two things that had to stay. The symptom index remains inline; the reference and script indexes moved to the on-demand routing file. The freed budget went into making the rules *stronger*, not shorter: the constraints section is now a table of thirteen non-negotiable constraints each paired with the check that catches a violation, and the tooling obligations are instructions whose violation is a defect (hedging language in SKILL.md: 1 line, down from a paragraph of hedged advice). Long references gained a navigation head so a reader can decide from the top whether to load one. **New: an executable test layer.** `tests/` (unit, CLI contract, no-device integration) plus `pytest.ini`, `tests/run_tests.py`, a minimal CI job, and `evals/evals.json` written but never run -- stated as such in the file. 608 passed / 158 skipped / 25 xfailed. The 25 xfails are a work order, not a pass: thirteen scripts report a missing input by exiting 1 instead of 2, seven let a traceback escape, four treat `--help` as an error, and `preflight --json` lacks a `status` field. A regression row for `dex_patch_bytes.py` reproduces a previous artifact byte-for-byte (`67ae1e58e7a44777e5ac8f9f823ab21e…`) and additionally pins the four bytes that may move. **Two real defects the new tests found in the tooling itself.** `check_repo.py` decoded subprocess output with the locale encoding, so on a GBK console a script printing an em dash in its usage line was reported as crashed; it now decodes UTF-8 explicitly. And a CLI contract test drove a *real attached device* through `coldstart.py` -- logcat, screenshots, five orphan `adb logcat` processes -- which is fixed twice over: child processes run in a private temporary cwd, and the fifteen device-bound scripts are never executed beyond `--help`/argument parsing. **Quoting on the device side is now one implementation.** `devsh.su` escaped only double quotes, so `;`, `$( )` and backticks in a caller-supplied value still reached the device shell while `coldstart.Device.shell` quoted correctly. Both use `scripts/device_shell.py` now: POSIX single-quote escaping, argv arrays by default, and identifier validation that refuses a malformed package, path or component with exit 2 instead of a traceback. The integration test that used to pin the *defect* (it asserted `su -c "…"` with `\"` escapes) now asserts the property, across five metacharacter payloads. Gates: check_repo 0 problems (including the content-reading identity scan over git ls-files), check_refs 0 dangling / 0 warning, check_routing coherent (53 symptom / 45 reference / 54 script rows), check_budget 0 failure / 0 warning with the always-loaded body now measured in tokens rather than in "narrative lines with the index excluded", check_commands 146 checked / 0 drift, pytest 608 passed. Not done, and stated rather than implied: CI has never run on a runner; the evals have never been executed; the 25 xfails are open; no device-side install/launch was performed in this pass.	2026-09-22 01:37:51 +08:00
inliver233	6cffc3d2ac	Absorption pass: take the mechanics from four external skill repositories, keep our discipline ... Four projects were cloned for comparison (reverse-skill, awesome-game-security, android-reverse-engineering-claude-skill, MobileRE-Skill) and read for what they do that this repository does not. None is vendored and none becomes a runtime dependency: what crosses over is a phase order, a checklist or a command pattern, with the source URL and the retrieval date recorded in the file that absorbed it. The rule applied to every candidate: does this make a judgement easier or a verification harder? The repository is a decision-and-verification layer, and the four things kept are all of that kind. new scripts/scan_leaks.py target identity scanned before publishing, with an explicit do-not-anonymize list and four RESULT=/exit states new references/precedents/ the positive half of the record: route including dead ends, a grade per assertion, measured pits, and a write-back checklist new scripts/svc_scan.py does a libc-level hook structurally see this call at all new scripts/anti_detect_probe.js observer-only: name the check, and report the environment it reads new references/desensitization-and-leak-scans.md new references/dart-aot.md sections the 32-bit snapshot's real string-record format check_repo.py now delegates the identity scan to scripts/scan_leaks.py and runs it over git ls-files, so the gate reads content instead of layout for the first time. An explicit file list cannot be narrowed by the default work-area exemptions -- that defect was caught by the gate itself. Two claims that this repository had already written down turned out to be wrong, and both are recorded as refuted rather than quietly rewritten: dart-aot.md the armv7 string table was documented as [len*2 u32le][UTF-16LE]. It is not. The same extractor keeps 4,980 chained entries on arm64 and zero on armv7, and the byte layer shows the 32-bit record is [header u32][byte-count u32le][UTF-8 payload]: two adjacent literals carry 0x46 (70) and 0x48 (72), exactly their byte lengths. The zero was a format mismatch, not an empty table. The engine-version banner on the same target is 66 bytes of "0.0.1" with a blank build id, so the documented regex returns a version-shaped lie. leak scan the pass that added the scanner found 26 strong hits inside its own evidence file on the day it was written -- the fixture's literal match values, quoted to prove the rules fire. The corpus may contain values; the published surface may not. Measured, not asserted. The check that fires was named on a public MASTG target: three arms with one variable, the control alive at the end and the probe arm dead in about 300 ms, with strstr("frida") at t=303 ms and no tombstone. Reproducibility is bounded honestly -- one full sequence in three arms, on a target whose whole window is sub-second. svc_scan.py's two independent decoders agree on an identical 214-site set, and ptrace-free dumping gained a negative boundary: a target whose dex is deflated inside its APK has no whole-image dex in memory to export, for reasons that say nothing about protection. Also in this pass: the detector-locating pipeline (detection-and-anti-analysis.md Step 3) with its branch conditions; the layered Java-to-svc descent and the dump's honesty boundary in advanced-unpacking.md; a sourced capability-gap list in toolchain.md where every row is graded URL-verified or measured; the RESULT=-token convention; and SKILL.md opening with an immediate-action block, because the symptom index and the gates were sitting in the part of a long file nobody reads. Gates: check_repo.py 0 problem, check_refs.py 0 dangling / 0 warning, check_budget.py 0 failure / 0 warning / 1 pre-existing note. The scan reports RESULT=leaks_found_strong_only, exit 0: four endpoint/weak hits, all of them addresses from the RFC 5737 documentation range in usage examples.	2026-09-21 22:51:09 +08:00
inliver233	6221a072ca	Benchmark pass: measure the documented routes, close five tool gaps, correct four claims ... Public targets under the existing routes, recorded per row in tests/benchmark.md with each row's own strength label: the MASTG crackmes (equal-length patch -> repack -> re-sign with a zero-change control, and the anti-debug race with its time-to-death baseline), DexPatcher's ezAndroid sample, two real split APK sets, and a self-built extraction-skeleton set. Hardening-shape discrimination now separates Java2C from an extraction shell, a VMP and JNI sinking. New: java2c_probe.py and java2c-and-jni-sinking.md; split-apk.md with repack.py growing set inventory, unified re-signing and merge; protobuf_decode_raw.py cross-checked against the official runtime; vmp_diff_harness.py and its cost table; kernelsu_syscall_mask.py with three kernel-side templates; stalker_trace.js gains Stalker.exclude() and a zero-event warning. Corrections, each because a measurement contradicted a recorded conclusion: the trivial-body ratio is bimodal rather than a threshold and the old threshold claim was deleted; a Dex-VMP verdict was withdrawn after dexdump contradicted a hand-written opcode table; the assumption that Stalker.exclude() fixes zero-event delivery is disproved (it keeps the process alive, nothing more); and a repack.py signing-path claim expired mid-pass when a second writer added one. Emulated and kernel-side routes are labelled unverified where no toolchain or device could run them; each evidence file states what was not run.	2026-09-21 21:57:23 +08:00
