For example, to disable the archive related functions just define + MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros). + + * Low-level Deflate/Inflate implementation notes: + + Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or + greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses + approximately as well as zlib. + + Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function + coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory + block large enough to hold the entire file. + + The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation. + + * zlib-style API notes: + + miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in + zlib replacement in many apps: + The z_stream struct, optional memory allocation callbacks + deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound + inflateInit/inflateInit2/inflate/inflateReset/inflateEnd + compress, compress2, compressBound, uncompress + CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly routines. + Supports raw deflate streams or standard zlib streams with adler-32 checking. + + Limitations: + The callback API's are not implemented yet. No support for gzip headers or zlib static dictionaries. + I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but + there are no guarantees that miniz.c pulls this off perfectly. + + * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by + Alex Evans. Supports 1-4 bytes/pixel images. + + * ZIP archive API notes: + + The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to + get the job done with minimal fuss. There are simple API's to retrieve file information, read files from + existing archives, create new archives, append new files to existing archives, or clone archive data from + one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h), + or you can specify custom file read/write callbacks. + + - Archive reading: Just call this function to read a single file from a disk archive: + + void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name, + size_t *pSize, mz_uint zip_flags); + + For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central + directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files. + + - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file: + + int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags); + + The locate operation can optionally check file comments too, which (as one example) can be used to identify + multiple versions of the same file in an archive. This function uses a simple linear search through the central + directory, so it's not very fast. + + Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and + retrieve detailed info on each file by calling mz_zip_reader_file_stat(). + + - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data + to disk and builds an exact image of the central directory in memory. The central directory image is written + all at once at the end of the archive file when the archive is finalized. + + The archive writer can optionally align each file's local header and file data to any power of 2 alignment, + which can be useful when the archive will be read from optical media. Also, the writer supports placing + arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still + readable by any ZIP tool. + + - Archive appending: The simple way to add a single file to an archive is to call this function: + + mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name, + const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags); + + The archive will be created if it doesn't already exist, otherwise it'll be appended to. + Note the appending is done in-place and is not an atomic operation, so if something goes wrong + during the operation it's possible the archive could be left without a central directory (although the local + file headers and file data will be fine, so the archive will be recoverable). + + For more complex archive modification scenarios: + 1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to + preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the + compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and + you're done. This is safe but requires a bunch of temporary disk space or heap memory. + + 2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(), + append new files as needed, then finalize the archive which will write an updated central directory to the + original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a + possibility that the archive's central directory could be lost with this method if anything goes wrong, though. + + - ZIP archive support limitations: + No spanning support. Extraction functions can only handle unencrypted, stored or deflated files. + Requires streams capable of seeking. + + * This is a header file library, like stb_image.c. To get only a header file, either cut and paste the + below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it. + + * Important: For best perf. be sure to customize the below macros for your target platform: + #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1 + #define MINIZ_LITTLE_ENDIAN 1 + #define MINIZ_HAS_64BIT_REGISTERS 1 + + * On platforms using

Benchmark & Crypto Mass Conservation (CMC) Protocol + +This document specifies the blind-labelling rules, conservation metrics, and exact steps required for any independent evaluator to reproduce ECDAT's benchmark results from scratch. + +--- + +## 1. Principles & Non-Negotiables + +### 1.1 Blind-Labelling Rule +1. **Ground Truth Before Rule Tuning**: Ground truth labels in `bench/truth.json` are established and committed in isolation before detector rules are run or tuned. +2. **Never Tune on HOLD**: Real-world evaluation datasets (`bench/real_world/`) serve as a strict HOLD corpus. No rule may be fitted to specific HOLD samples. +3. **Honest Accounting**: Residue is never silently discarded. A high residue figure indicates unexplained evidence mass and represents a real finding, not a failure to hide. + +### 1.2 Adversarial Independence +1. **Extraction Independence**: The feature extractors (`backend/engine/extract/`) detect structural suspicion mass (entropy anomalies, bijection tables, ARX patterns, big-integer loop structures, framing shapes, and literal densities) without importing or knowing anything about algorithmic rules. +2. **CI-Enforced Boundary**: Any import from `engine.rules` or rule-specific logic into `engine.extract` fails CI immediately. + +### 1.3 Conservation Invariant +Every artifact evaluated must satisfy the fundamental conservation invariant: +$$\text{attributed\_mass} + \text{excluded\_mass} + \text{residue\_mass} = \text{total\_suspicion\_mass}$$ +- **Attributed Mass**: Suspicion intervals overlapping with verified cryptographic finding spans. +- **Excluded Mass**: Suspicion intervals matched against falsifiable exclusion predicates (e.g., CRC32 tables, Base64 character maps, dead/unreachable code). +- **Residue Mass**: Unexplained suspicion intervals, clustered by content hash for cross-estate stability. +- **Coverage Ratio**: $\frac{\text{attributed\_mass}}{\text{total\_suspicion\_mass}}$ (reported honestly in every CBOM). + +--- + +## 2. Evaluation Metrics + +### Detection Performance +- **True Positives ($TP$)**: Detections matching ground truth on `(path, family, function, line)`. +- **False Positives ($FP$)**: Detections produced by the engine not present in ground truth. +- **False Negatives ($FN$)**: Ground truth usages not discovered by the engine. +- **Precision**: $\frac{TP}{TP + FP}$ (CI-enforced floor: $\ge 0.9500$). +- **Recall**: $\frac{TP}{TP + FN}$. +- **F1 Score**: $\frac{2 \times \text{Precision} \times \text{Recall}}{\text{Precision} + \text{Recall}}$. + +### Coverage Performance +- **Total Suspicion Mass ($M_{\text{total}}$)**: Cumulative magnitude of all structural evidence spans. +- **Attributed Mass ($M_{\text{attr}}$)**: Evidence mass explained by rule findings. +- **Residue Mass ($M_{\text{res}}$)**: Unexplained evidence mass. +- **Coverage Ratio**: $\frac{M_{\text{attr}}}{M_{\text{total}}}$. + +--- + +## 3.

A cryptographic object passed through multiple wrapper layers or assigned to deeply nested structures across module boundaries requires inter-procedural points-to analysis. +2. **Dynamic Invocation / Reflection**: + Java reflection (`Class.forName(...).getMethod(...)`), .NET reflection, or Python `getattr()` dynamic calls without string literals cannot be statically attributed. They surface as residue mass if structural primitives (tables/entropy) are present, but remain unattributed without dynamic tracing. +3. **Non-Cryptographic Big-Integer Loops**: + Scientific math and arbitrary-precision integer libraries (e.g. GMP wrappers) that perform modular exponentiation for non-cryptographic calculations may trigger `bigint.py` suspicion spans. These must be handled via `ecdat debt accept` with documented owner justifications. +4. **Stripped Binary Attribution**: + In stripped binaries with no symbols, the engine reliably flags evidence mass (via AES S-box tables, SHA-256 K-tables, and ARX opcode density), but cannot pinpoint higher-level protocol names without symbolic metadata. diff --git a/backend/bench/public/score.py b/backend/bench/public/score.py new file mode 100644 index 0000000..b81e39d --- /dev/null +++ b/backend/bench/public/score.py @@ -0,0 +1,397 @@ +"""Universal CycloneDX 1.6 CBOM Benchmark Scorer. + +Scores ANY tool's CycloneDX CBOM output against ground truth. +Measures: +1.

Coverage measures what fraction of *all* extracted cryptographic suspicion evidence across an actual target codebase was accounted for ($M_{\text{attributed}} / M_{\text{total}}$). A tool can have 99% recall on known library patterns while achieving low coverage on proprietary, hand-rolled, or obfuscated crypto it has never seen. + +**Why is a high residue number honest rather than embarrassing?** +High residue openly reports unmodeled, suspicious cryptographic evidence (unexplained S-boxes, ARX rotations, modular loops) instead of sweeping it under the rug. Hiding unexplained evidence produces an illusion of complete safety that misleads security officers. Presenting residue with exact byte ranges empowers engineering teams to investigate, promote to rules, or document debt. + +**Why can't an ML-based tool produce a stable residue set?** +ML and LLM detectors rely on probabilistic token distributions that fluctuate across inference runs, temperatures, and model versions. Residue clusters require deterministic byte-level attribution and content-hash invariance to track cryptographic debt reliably across scans. If evidence shifts spuriously without underlying code changes, debt ledgers, drift tracking, and attestation digests become useless. + +**What did we deliberately NOT build, and why?** +We deliberately did not build multi-tenant RBAC/SSO, automatic in-place code rewrites, or direct cloud KMS discovery for Azure Key Vault and GCP KMS (which are honestly marked `[Roadmap]` alongside our LocalStack AWS KMS). We do not perform unconstrained dynamic execution or symbolic execution of arbitrary stripped binaries. Our scope is focused strictly on deterministic, air-gapped discovery, mass conservation coverage, and quantum-risk scoring. + +--- + +### Engineering & Methodology Details + +**Why not use an LLM/ML for detection or scoring?** +Determinism and auditability: the same input must always produce the +same finding and the same score, with a reason a reviewer can trace back +to a fixed rule (`backend/engine/families.py`'s V-table, +`backend/engine/risk.py`'s formula), not a model's internal state that +can drift between runs or providers. `scripts/verify_airgap.py` enforces +this mechanically — zero LLM/AI-SDK imports permitted anywhere in +`api/`/`engine/`/`scheduler/`. + +**Do you cover C/C++ and firmware?** +C/C++ source: yes — `backend/engine/source_c.py`, real precision/recall +in the per-language table (`docs/BENCHMARK.md`).

Fixed the assertion to match +the real, correct new behavior (2 rows, in order) rather than weakening +it. Re-ran: 217/217 passed. Also rebased the whole branch onto +`chore/repo-hygiene`'s actual merge commit (`3b9ecad`) -- the branch had +silently forked from a pre-hygiene `main` despite the mandate's own +"rebase on main first" prerequisite; clean rebase, no conflicts, gates +re-verified green after (218/218, the +1 being M4's own new test). + +### M4: coverage in drift and trend +Found two real gaps while implementing: `ScanSnapshot.coverageRatio`/ +`residueMass` existed in the Python model and DB schema (M1/M2) but were +never populated by `create_snapshot()`, and were never declared in +`contracts/openapi.yaml` at all (a real blind spot in +`scripts/contract_diff.py`, which only flags contract fields missing +from the app, never the reverse -- noted, not fixed, out of this track's +`contracts/openapi.yaml`-only ownership of that boundary). +`DriftSummary.coverageDelta`/`residueMassDelta` were declared in the +contract but never computed. + +Wired all of it: `create_snapshot()` now looks up the scan's +already-persisted `CoverageCertificate` and carries it onto the +snapshot; `db.snapshot_to_record()`/`record_to_snapshot()` pass the +fields through; `calculate_drift()` computes the deltas from the two +snapshots being compared. Added the missing `ScanSnapshot` properties to +`contracts/openapi.yaml`. + +Also found and fixed a real, currently-dormant bug while wiring this: +`save_coverage()` persisted a certificate keyed by `cert.scanId` (a +caller-supplied field) instead of its own explicit `scan_id` parameter -- +harmless today only because nothing in `engine/` yet populates +`ScanResult.coverage_certificate`, so the fallback path always +self-consistently set `cert.scanId == scan_id`. Surfaced immediately by +M4's own test (a manually-constructed certificate for the "before" and +"after" snapshots): `get_coverage_certificate(scan_id)` returned `None` +for a real scan whose cert had been silently saved under a different +key. Fixed by forcing `cert.scanId = scan_id` inside `save_coverage()` +itself. + +New test, real HTTP endpoint, not just the store function: +`test_drift_reports_falling_coverage_when_unexplained_crypto_appears` +(`tests/test_targets_scheduler.py`) -- two snapshots with real, different +coverage certificates (1.0 -> 0.758 coverage, 0.0 -> 24.2 residue mass) +produce a drift response whose `summary.coverageDelta` is negative and +`residueMassDelta` is positive, proving the exit criteria: coverage +falls even with **zero new Findings**, because unexplained residue is +the real signal, not just finding count. + +### Real request/response evidence (2026-09-21, live server, port 8020) +``` +$ curl -sS http://127.0.0.1:8020/api/v1/scans/scan_stub_001/coverage +{"scanId":"scan_stub_001","artifactCount":482,"totalMass":100.0, + "attributedMass":100.0,"excludedMass":0.0,"residueMass":0.0, + "coverageRatio":1.0,"residueClusterCount":0, + "computedAt":"2026-09-21T01:35:45.761267Z"} + +$ curl -sS http://127.0.0.1:8020/api/v1/residue +[] + +$ curl -sS http://127.0.0.1:8020/api/v1/criticality +[] + +$ curl -sS http://127.0.0.1:8020/api/v1/cloud/keys +{"keys":[],"roadmap":"[Roadmap] AWS KMS via LocalStack is actively + supported in v1.0.
