([Gitea: Git with a cup of tea][4]) + +So you can add a third catalog for **native/binary mapping** that behaves the same way. + +--- + +## 2) Layering strategy: what to implement (and in what order) + +You want a **resolver pipeline** with strict ordering from “hard evidence” → “soft evidence”. + +### Layer 0 — In‑image authoritative mapping (highest confidence) + +These sources are authoritative because they come from within the artifact: + +1. **OS package DB present** (dpkg/rpm/apk): + +* Map `path → package` using file ownership lists. +* If you can also compute file hashes/build‑ids, store them as evidence. + +2. **Language ecosystem metadata present** (already handled by language analyzers): + +* For example, a Python wheel RECORD or a Go buildinfo section can directly imply module versions. + +**Decision rule**: If a binary file is owned by an OS package, **prefer that** over any external mapping index. + +### Layer 1 — “Build provenance” mapping via build IDs / UUIDs (strong, portable) + +When package DB is missing (distroless/scratch), use **compiler/linker stable IDs**: + +* ELF: `.note.gnu.build-id` +* Mach‑O: `LC_UUID` +* PE: CodeView (PDB GUID+Age) / build signature + +This should be your primary fallback because it survives stripping and renaming. + +### Layer 2 — Hash mapping for curated or vendor‑pinned binaries (strong but brittle across rebuilds) + +Use SHA‑256 → PURL mapping when: + +* binaries are redistributed unchanged (busybox, chromium, embedded runtimes) +* you maintain a curated “known binaries” manifest + +StellaOps already has “curated binary manifest generation” mentioned in its repo history, and a `vendor/manifest.json` concept exists (for pinned artifacts / binaries in the system). ([Gitea: Git with a cup of tea][5]) +For your ops environment you’ll create a similar manifest **for your fleet**. + +### Layer 3 — Dependency closure constraints (helpful as a disambiguator, not a primary mapper) + +If the binary’s DT_NEEDED / imports point to libs you *can* identify, you can use that to disambiguate multiple possible candidates (“this openssl build-id matches, but only one candidate has the required glibc baseline”). + +This must remain deterministic and rules‑based. + +### Layer 4 — Heuristic hints (never change the core SBOM by default) + +Examples: + +* symbol version patterns (`GLIBC_2.28`, etc.) +* embedded version strings +* import tables +* compiler metadata + +These produce **Unknown evidence/hints**, not a resolved identity, unless a special “heuristics allowed” flag is turned on. + +### Layer 5 — Unknowns Registry output (mandatory when you can’t decide) + +If a mapping can’t be made decisively: + +* emit Unknowns (identity_gap, missing_build_id, version_conflict, etc.) ([Gitea: Git with a cup of tea][2]) + This is not optional; it’s how you prevent silent false negatives. + +--- + +## 3) Concrete data model you should implement + +### 3.1 Binary identity record + +Create a single canonical identity structure that *every layer* uses: + +```csharp +public enum BinaryFormat { Elf, Pe, MachO, Unknown } + +public sealed record BinaryIdentity( + BinaryFormat Format, + string Path, // normalized (posix style), rooted at image root + string Sha256, // always present + string?

you should enforce so triage is **explainable** and approvals are **provably evidence‑linked**. + +--- + +## 1) Start with the invariants (the rules your system must never violate) + +If you implement nothing else, implement these invariants—they’re what make the UX trustworthy and the approvals auditable. + +### Artifact anchoring invariant + +Every finding, every piece of evidence, and every approval must be anchored to an immutable **subject digest** (e.g., container image digest `sha256:…`, binary SHA, or SBOM digest). + +* No “latest tag” approvals. +* No “approve commit” without mapping to the built artifact digest. + +### Evidence closure invariant + +A policy decision is only valid if it references **exactly** the evidence it used: + +* `inputs.sbom_ref` +* `inputs.vex_ref` +* `inputs.reachability_ref` (optional but recommended) +* `inputs.scan_ref` (optional) +* and any config/IaC refs used for boundary/exposure. + +### Signature chain invariant + +Evidence is only admissible if it is: + +1. structured (machine readable), +2. signed (DSSE/in‑toto), +3. verifiable (trusted identity/keys), +4. retrievable by digest. + +DSSE is specifically designed to authenticate both the message and its type (payload type) and avoid canonicalization pitfalls. ([GitHub][1]) + +### Staleness invariant + +Evidence must have: + +* `last_seen` and `expires_at` (or TTL), +* a “stale evidence” behavior in policy (deny or degrade score). + +--- + +## 2) Choose the canonical formats and where you’ll store “proof” + +### Attestation envelope: DSSE + in‑toto Statement + +Use: + +* **in‑toto Attestation Framework** “Statement” as the payload model (“subject + predicateType + predicate”). ([GitHub][2]) +* Wrap it in **DSSE** for signing. ([GitHub][1]) +* If you use Sigstore bundles, the DSSE envelope is expected to carry an in‑toto statement and uses `payloadType` like `application/vnd.in-toto+json`. ([Sigstore][3]) + +### SBOM format: CycloneDX or SPDX + +* SPDX is an ISO/IEC standard and has v3.0 and v2.3 lines in the ecosystem. ([spdx.dev][4]) +* CycloneDX is an ECMA standard (ECMA‑424) and widely used for application security contexts. ([GitHub][5]) + +Pick one as **your canonical** (internally), but ingest both. + +### VEX format: OpenVEX (practical) + map to “classic” VEX statuses + +VEX’s value is triage noise reduction: vendors can assert whether a product is affected, fixed, under investigation, or not affected. ([NTIA][6]) +OpenVEX is a minimal, embeddable implementation of VEX intended for interoperability. ([GitHub][7]) + +### Where to store proof: OCI registry referrers + +Use OCI “subject/referrers” so proofs travel with the artifact: + +* OCI 1.1 introduces an explicit `subject` field and referrers graph for signatures/attestations/SBOMs. ([opencontainers.org][8]) +* ORAS documentation explains linking artifacts via `subject`. ([Oras][9]) +* Microsoft docs show `oras attach … --artifact-type …` patterns (works across registries that support referrers). ([Microsoft Learn][10]) + +--- + +## 3) System architecture (services + data flow) + +### Services (minimum set) + +1. **Ingestor** + + * Pulls scanner outputs (SCA/SAST/IaC), SBOM, runtime signals. +2. **Evidence Builder** + + * Computes reachability, entrypoints, boundary/auth context, score explanation. +3. **Attestation Service** + + * Creates in‑toto statements, wraps DSSE, signs (cosign/KMS), stores to registry. +4. **Policy Engine** + + * Evaluates allow/deny + reason codes, emits signed decision attestation. + * Use OPA/Rego for maintainable declarative policies.
