**Description**: Add an offline-friendly perf harness for EPSS ingest without committing a huge static dataset.

|
||||
**Deliverables**:
|
||||
- New test project: `src/Scanner/__Tests/StellaOps.Scanner.Storage.Performance.Tests/`
|
||||
- Deterministic generator: 310k rows with fixed seed, stable row order, and controlled CVE distribution.
|
||||
- Test tagged so it does not run in default CI (`[Trait("Category","Performance")]` or equivalent).
|
||||
- Local run snippet (exact `dotnet test` invocation + required env vars for Testcontainers).
|
||||
- Perf harness: `src/Scanner/__Benchmarks/StellaOps.Scanner.Storage.Epss.Perf/`
|
||||
- Deterministic generator: 310k rows with fixed seed, stable row order, and reproducible SHA-256 hashes.
|

- Local run snippet (exact `dotnet run` invocation + required env vars for Testcontainers).
|

|

**Acceptance Criteria**:
|
||||
- [ ] Generator produces identical output across runs (same seed ⇒ same SHA-256 of CSV bytes)
|
||||
- [ ] Perf test runs locally in <= 5 minutes on a dev machine (budget validation happens in CI)

# Transparency (DOCS-ATTEST-74-002)
|
||||
|
||||
- Optional Rekor/witness integration.
|
||||
- In sealed mode, use bundled checkpoints and disable live witness fetch.
|
||||
- Verification: compare embedded checkpoint with bundled; log discrepancies.
|
||||
- Record transparency fields on verification result: `{uuid, logIndex, checkpointHash}`.
|
||||
Last updated: 2025-12-18
|
||||
|
||||
## Purpose
|
||||
|
||||
StellaOps uses transparency logs (Sigstore Rekor v2 or equivalent) to provide tamper-evident, timestamped anchoring for DSSE bundles.
|
||||
|
||||
This document freezes the **offline verification inputs** used by Attestor in sealed/air-gapped operation and points to the canonical schema for `rekor-receipt.json`.
|
||||
|
||||
## Offline Inputs (Air-Gap / Sealed Mode)
|
||||
|
||||
Baseline directory layout is defined in `docs/product-advisories/14-Dec-2025 - Offline and Air-Gap Technical Reference.md`:
|
||||
|
||||
```
|
||||
/evidence/
|
||||
keys/
|
||||
tlog-root/ # pinned transparency log public key(s)
|
||||
tlog/
|
||||
checkpoint.sig # signed tree head / checkpoint (note format)
|
||||
entries/ # *.jsonl entry pack (leaves + proofs)
|
||||
```
|
||||
|
||||
### Rekor Receipt (`rekor-receipt.json`)
|
||||
|
||||
The offline kit (or any offline DSSE evidence pack) may include a Rekor receipt alongside a DSSE statement.
|
||||
|
||||
- **Schema:** `docs/schemas/rekor-receipt.schema.json`
|
||||
- **Source:** `docs/product-advisories/14-Dec-2025 - Rekor Integration Technical Reference.md` (Section 13.1) and `docs/product-advisories/14-Dec-2025 - Offline and Air-Gap Technical Reference.md` (Section 1.4)
|
||||
|
||||
Fields:
|
||||
- `uuid`: Rekor entry UUID.
|
||||
- `logIndex`: Rekor log index (integer, >= 0).
|
||||
- `rootHash`: expected Merkle tree root hash (lowercase hex, 32 bytes).
|
||||
- `hashes`: Merkle inclusion path hashes (lowercase hex, 32 bytes each; ordered as provided by Rekor).
|
||||
- `checkpoint`: either the signed checkpoint note text (UTF-8) or a relative path (e.g., `checkpoint.sig`, `tlog/checkpoint.sig`) resolved relative to the receipt file.
|
||||
|
||||
### Checkpoint (`checkpoint.sig`)
|
||||
|
||||
`/evidence/tlog/checkpoint.sig` is the pinned signed tree head used for offline verification.
|
||||
|
||||
Contract:
|
||||
- Content is **UTF-8 text** using **LF** line endings.
|
||||
- The checkpoint **MUST** parse to the checkpoint body shape used by `CheckpointSignatureVerifier` (origin, tree size, base64 root hash, optional timestamp).
|
||||
- In offline verification, the checkpoint from receipts SHOULD match the pinned checkpoint (tree size + root hash).
|
||||
|
||||
### Entry Pack (`entries/*.jsonl`)
|
||||
|
||||
`/evidence/tlog/entries/*.jsonl` is an optional-but-recommended offline mirror snapshot for bulk audit/replay.
|
||||
|
||||
Contract:
|
||||
- Files are **NDJSON** (one JSON object per line).
|
||||
- Each line uses the "Rekor Entry Structure" defined in `docs/product-advisories/14-Dec-2025 - Rekor Integration Technical Reference.md` (Section 4).
|
||||
- **Deterministic ordering**:
|
||||
- File names sort lexicographically (Ordinal).
|
||||
- Within each file, lines sort by `rekor.logIndex` ascending.
|
||||
|
||||
## Offline Verification Rules (High Level)
|
||||
|
||||
1. Load the pinned Rekor log public key from `/evidence/keys/tlog-root/` (rotation is handled by shipping a new key file alongside the updated checkpoint snapshot).
|
||||
2. Verify the checkpoint signature (when configured) and extract tree size + root hash.
|
||||
3. For each `rekor-receipt.json`, verify:
|
||||
- inclusion proof path resolves to `rootHash` for the given leaf hash,
|
||||
- receipt checkpoint root matches the pinned checkpoint root (same tree head).
|
||||
4. Optionally, validate that each receipt's UUID/digest appears in the entry pack and that the recomputed Merkle root matches the pinned checkpoint.
