# Determinism Benchmark Suite
> **Purpose:** Verify that StellaOps produces bit-identical results across replays.
> **Status:** Active
> **Sprint:** SPRINT_3850_0001_0001 (Competitive Gap Closure)
## Overview
Determinism is a core differentiator for StellaOps:
- Same inputs → same outputs (bit-identical)
- Replay manifests enable audit verification
- No hidden state or environment leakage
## What Gets Tested
### Canonical JSON
- Object key ordering (alphabetical)
- Number formatting consistency
- UTF-8 encoding without BOM
- No whitespace variation
### Scan Manifests
- Same artifact + same feeds → same manifest hash
- Seed values propagate correctly
- Timestamp handling (fixed UTC)
### Proof Bundles
- Root hash computation
- DSSE envelope determinism
- ProofLedger node ordering
### Score Computation
- Same manifest → same score
- Lattice merge is associative/commutative
- Policy rule ordering doesn't affect outcome
## Test Cases
### TC-001: Canonical JSON Determinism
```bash
# Run same object through CanonJson 100 times
# All hashes must match
```
### TC-002: Manifest Hash Stability
```bash
# Create manifest with identical inputs
# Verify ComputeHash() returns same value
```
### TC-003: Cross-Platform Determinism
```bash
# Run on Linux, Windows, macOS
# Compare output hashes
```
### TC-004: Feed Snapshot Determinism
```bash
# Same feed snapshot hash → same scan results
```

# Smart-Diff Benchmark Suite
> **Purpose:** Prove deterministic smart-diff reduces noise compared to naive diff.
> **Status:** Active
> **Sprint:** SPRINT_3850_0001_0001 (Competitive Gap Closure)
## Overview
The Smart-Diff feature enables incremental scanning by:
1. Computing structural diffs of SBOMs/dependencies
2. Identifying only changed components
3. Avoiding redundant scanning of unchanged packages
4. Producing deterministic, reproducible diff results
## Test Cases
### TC-001: Layer-Aware Diff
Tests that Smart-Diff correctly handles container layer changes:
- Adding a layer
- Removing a layer
- Modifying a layer (same hash, different content)
### TC-002: Package Version Diff
Tests accurate detection of package version changes:
- Minor version bump
- Major version bump
- Pre-release version handling
- Epoch handling (RPM)
### TC-003: Noise Reduction
Compares smart-diff output vs naive diff for real-world images:
- Measure CVE count reduction
- Measure scanning time reduction
- Verify determinism (same inputs → same outputs)
### TC-004: Deterministic Ordering
Verifies that diff results are:
- Sorted by component PURL
- Ordered consistently across runs
- Independent of filesystem ordering

```
## Metrics Collected
| Metric | Description |
|--------|-------------|
| `diff_time_ms` | Time to compute diff |
| `changed_packages` | Number of packages marked as changed |
| `false_positive_rate` | Packages incorrectly flagged as changed |
| `determinism_score` | 1.0 if all runs produce identical output |
| `noise_reduction_pct` | % reduction vs naive diff |
## Expected Results
For typical Alpine base image upgrades (3.18 → 3.19):
- **Naive diff:** ~150 packages flagged as changed
- **Smart diff:** ~12 packages actually changed
- **Noise reduction:** ~92%

# Unknowns Tracking Benchmark Suite
> **Purpose:** Verify epistemic uncertainty tracking and unknown state management.
> **Status:** Active
> **Sprint:** SPRINT_3850_0001_0001 (Competitive Gap Closure)
## Overview
StellaOps tracks "unknowns" - gaps in knowledge that affect confidence:
- Missing SBOM components
- Unmatched CVEs
- Stale feed data
- Zero-day windows
- Analysis limitations
## What Gets Tested
### Unknown State Lifecycle
1. Detection of unknown conditions
2. Propagation to affected findings
3. Score penalty application
4. Resolution tracking
### Unknown Categories
- `SBOM_GAP`: Component not in SBOM
- `CVE_UNMATCHED`: CVE without component mapping
- `FEED_STALE`: Feed data older than threshold
- `ZERO_DAY_WINDOW`: Time between disclosure and feed update
- `ANALYSIS_LIMIT`: Depth/timeout constraints
### Score Impact
- Each unknown type has a penalty weight
- Penalties reduce overall confidence
- Resolved unknowns restore confidence
## Test Cases
### TC-001: SBOM Gap Detection
```json
{
"scenario": "Package in image not in SBOM",
"input": {
"image_packages": ["openssl@3.0.1", "curl@7.86"],
"sbom_packages": ["openssl@3.0.1"]
},
"expected": {
"unknowns": [{ "type": "SBOM_GAP", "package": "curl@7.86" }],
"confidence_penalty": 0.15
}
}
```
### TC-002: Zero-Day Window Tracking
```json
{
"scenario": "CVE disclosed before feed update",
"input": {
"cve_disclosure": "2025-01-01T00:00:00Z",
"feed_update": "2025-01-03T00:00:00Z",
"scan_time": "2025-01-02T12:00:00Z"
},
"expected": {
"unknowns": [{
"type": "ZERO_DAY_WINDOW",
"cve": "CVE-2025-0001",
"window_hours": 36
}],
"risk_note": "Scan occurred during zero-day window"
}
}
```
### TC-003: Feed Staleness
```json
{
"scenario": "NVD feed older than 24 hours",
"input": {
"feed_last_update": "2025-01-01T00:00:00Z",
"scan_time": "2025-01-02T12:00:00Z",
"staleness_threshold_hours": 24
},
"expected": {
"unknowns": [{
"type": "FEED_STALE",
"feed": "nvd",
"age_hours": 36
}]
}
}
```
### TC-004: Score Penalty Application
```json
{
"scenario": "Multiple unknowns compound penalty",
"input": {
"base_confidence": 0.95,
"unknowns": [
{ "type": "SBOM_GAP", "penalty": 0.15 },
{ "type": "FEED_STALE", "penalty": 0.10 }
]
},
"expected": {
"final_confidence": 0.70,
"penalty_formula": "0.95 * (1 - 0.15) * (1 - 0.10)"
}
}
```

# VEX Lattice Benchmark Suite
> **Purpose:** Verify VEX lattice merge semantics and jurisdiction rules.
> **Status:** Active
> **Sprint:** SPRINT_3850_0001_0001 (Competitive Gap Closure)
## Overview
StellaOps implements VEX (Vulnerability Exploitability eXchange) with:
- Lattice-based merge semantics (stable outcomes)
- Jurisdiction-specific trust rules (US/EU/RU/CN)
- Source precedence and confidence weighting
- Deterministic conflict resolution
## What Gets Tested
### Lattice Properties
- Idempotency: merge(a, a) = a
- Commutativity: merge(a, b) = merge(b, a)
- Associativity: merge(merge(a, b), c) = merge(a, merge(b, c))
- Monotonicity: once "not_affected", never regresses
### Status Precedence
Order from most to least specific:
1. `not_affected` (strongest)
2. `affected` (with fix)
3. `under_investigation`
4. `affected` (no fix)
### Jurisdiction Rules
- US: FDA/NIST sources preferred
- EU: ENISA/BSI sources preferred
- RU: FSTEC sources preferred
- CN: CNVD sources preferred
## Test Cases
### TC-001: Idempotency
```json
{
"input_a": { "status": "not_affected", "justification": "vulnerable_code_not_in_execute_path" },
"input_b": { "status": "not_affected", "justification": "vulnerable_code_not_in_execute_path" },
"expected": { "status": "not_affected", "justification": "vulnerable_code_not_in_execute_path" }
}
```
### TC-002: Commutativity
```json
{
"merge_ab": "merge(vendor_vex, nvd_vex)",
"merge_ba": "merge(nvd_vex, vendor_vex)",
"expected": "identical_result"
}
```
### TC-003: Associativity
```json
{
"lhs": "merge(merge(a, b), c)",
"rhs": "merge(a, merge(b, c))",
"expected": "identical_result"
}
```
### TC-004: Conflict Resolution
```json
{
"vendor_says": "not_affected",
"nvd_says": "affected",
"expected": "not_affected",
"reason": "vendor_has_higher_precedence"
}
```
### TC-005: Jurisdiction Override
```json
{
"jurisdiction": "EU",
"bsi_says": "not_affected",
"nist_says": "affected",
"expected": "not_affected",
"reason": "bsi_preferred_in_eu"
}
```

# Regulator-Grade Threat & Evidence Model
## Supply-Chain Risk Decisioning Platform (Reference: “Stella Ops”)
**Document version:** 1.0
**Date:** 2025-12-19
**Intended audience:** Regulators, third-party auditors, internal security/compliance, and engineering leadership
**Scope:** Threat model + evidence model for a platform that ingests SBOM/VEX and other supply-chain signals, produces risk decisions, and preserves an audit-grade evidence trail.
---
## 1. Purpose and Objectives
This document defines:
1. A **threat model** for a supply-chain risk decisioning platform (“the Platform”) and its critical workflows.
2. An **evidence model** describing what records must exist, how they must be protected, and how they must be presented to support regulator-grade auditability and non-repudiation.
The model is designed to support the supply-chain transparency goals behind SBOM/VEX and secure software development expectations (e.g., SSDF), and to be compatible with supply-chain risk management (C‑SCRM) and control-based assessments (e.g., NIST control catalogs).
---
## 2. Scope, System Boundary, and Assumptions
### 2.1 In-scope system functions
The Platform performs the following high-level functions:
* **Ingest** software transparency artifacts (e.g., SBOMs, VEX documents), scan results, provenance attestations, and policy inputs.
* **Normalize** to a canonical internal representation (component identity graph + vulnerability/impact graph).
* **Evaluate** with a deterministic policy engine to produce decisions (e.g., allow/deny, risk tier, required remediation).
* **Record** an audit-grade evidence package supporting each decision.
* **Export** reports and attestations suitable for procurement, regulator review, and downstream consumption.
### 2.2 Deployment models supported by this model
This model is written to cover:
* **On‑prem / air‑gapped** deployments (offline evidence and curated vulnerability feeds).
* **Dedicated single-tenant hosted** deployments.
* **Multi-tenant SaaS** deployments (requires stronger tenant isolation controls and evidence).
### 2.3 Core assumptions
* SBOM is treated as a **formal inventory and relationship record** for components used to build software.
* VEX is treated as a **machine-readable assertion** of vulnerability status for a product, including “not affected / affected / fixed / under investigation.”
* The Platform must be able to demonstrate **traceability** from decision → inputs → transformations → outputs, and preserve “known unknowns” (explicitly tracked uncertainty).
* If the Platform is used in US federal acquisition contexts, it must anticipate evolving SBOM minimum element guidance; CISA’s 2025 SBOM minimum elements draft guidance explicitly aims to update the 2021 NTIA baseline to reflect tooling and maturity improvements. ([Federal Register][1])
---
## 3. Normative and Informative References
This model is aligned to the concepts and terminology used by the following:
* **SBOM minimum elements baseline (2021 NTIA)** and the “data fields / automation support / practices and processes” structure.
* **CISA 2025 SBOM minimum elements draft guidance** (published for comment; successor guidance to NTIA baseline per the Federal Register notice). ([Federal Register][1])

## 4. System Overview
### 4.1 Logical architecture
**Core components:**
1. **Ingestion Gateway**
* Accepts SBOM, VEX, provenance attestations, scan outputs, and configuration inputs.
* Performs syntactic validation, content hashing, and initial authenticity checks.
2. **Normalization & Identity Resolution**
* Converts formats (SPDX, CycloneDX, proprietary) into a canonical internal model.
* Resolves component IDs (purl/CPE/name+version), dependency graph, and artifact digests.
3. **Evidence Store**
* Content-addressable object store for raw artifacts plus derived artifacts.
* Append-only metadata index (event log) referencing objects by hash.
4. **Policy & Decision Engine**
* Deterministic evaluation engine for risk policy.
* Produces a decision plus a structured explanation and “unknowns.”
5. **Attestation & Export Service**
* Packages decisions and evidence references as signed statements (DSSE/in‑toto compatible). ([GitHub][7])
* Optional transparency publication (e.g., Rekor or private transparency log). ([Sigstore][8])
### 4.2 Trust boundaries
**Primary trust boundaries:**
* **TB‑1:** External submitter → Ingestion Gateway
* **TB‑2:** Customer environment → Platform environment (for hosted)
* **TB‑3:** Policy authoring plane → decision execution plane
* **TB‑4:** Evidence Store (write path) → Evidence Store (read/audit path)
* **TB‑5:** Platform signing keys / KMS / HSM boundary → application services
* **TB‑6:** External intelligence feeds (vulnerability databases, advisories) → internal curated dataset
---
## 5. Threat Model
### 5.1 Methodology
This model combines:
* **STRIDE** for platform/system threats (spoofing, tampering, repudiation, information disclosure, denial of service, elevation of privilege).
* **SLSA threat clustering (A–I)** for supply-chain pipeline threats relevant to artifacts being evaluated and to the Platform’s own supply chain. ([SLSA][5])
Threats are evaluated as: **Impact × Likelihood**, with controls grouped into **Prevent / Detect / Respond**.
### 5.2 Assets (what must be protected)
**A‑1: Decision integrity assets**
* Final decision outputs (allow/deny, risk scores, exceptions).
* Decision explanations and traces.
* Policy rules and parameters (including weights/thresholds).
**A‑2: Evidence integrity assets**
* Original input artifacts (SBOM, VEX, provenance, scan outputs).
* Derived artifacts (normalized graphs, reachability proofs, diff outputs).
* Evidence index and chain-of-custody metadata.
**A‑3: Confidentiality assets**
* Customer source code and binaries (if ingested).
* Private SBOMs/VEX that reveal internal dependencies.
* Customer environment identifiers and incident details.
**A‑4: Trust anchor assets**
* Signing keys (decision attestations, evidence hashes, transparency submissions).
* Root of trust configuration (certificate chains, allowed issuers).
* Time source and timestamping configuration.
**A‑5: Availability assets**
* Evidence store accessibility.
* Policy engine uptime.
* Interface endpoints and batch processing capacity.
### 5.3 Threat actors
* **External attacker** seeking to:
* Push a malicious component into the supply chain,
* Falsify transparency artifacts,
* Or compromise the Platform to manipulate decisions/evidence.
* **Malicious insider** (customer or Platform operator) seeking to:
* Hide vulnerable components,
* Suppress detections,
* Or retroactively alter records.
* **Compromised CI/CD or registry** affecting provenance and artifact integrity (SLSA build/distribution threats). ([SLSA][5])
* **Curious but non-malicious parties** who should not gain access to sensitive SBOM details (confidentiality and least privilege).
### 5.4 Key threat scenarios and required mitigations
Below are regulator-relevant threats that materially affect auditability and trust.
---
### T‑1: Spoofing of submitter identity (STRIDE: S)
**Scenario:**
An attacker submits forged SBOM/VEX/provenance claiming to be a trusted supplier.
**Impact:**
Decisions are based on untrusted artifacts; audit trail is misleading.
**Controls (shall):**
* Enforce strong authentication for ingestion (mTLS/OIDC + scoped tokens).
* Require artifact signatures for “trusted supplier” classification; verify signature chain and allowed issuers.
* Bind submitter identity to evidence record at ingestion time (AU-style accountability expectations). ([NIST Computer Security Resource Center][4])
**Evidence required:**
* Auth event logs (who/when/what).
* Signature verification results (certificate chain, key ID).
* Hash of submitted artifact (content-addressable ID).
---
### T‑2: Tampering with stored evidence (STRIDE: T)
**Scenario:**
An attacker modifies an SBOM, a reachability artifact, or an evaluation trace after the decision, to change what regulators/auditors see.
**Impact:**
Non-repudiation and auditability collapse; regulator confidence lost.
**Controls (shall):**
* Evidence objects stored as **content-addressed blobs** (hash = identifier).
* **Append-only metadata log** referencing evidence hashes (no in-place edits).
* Cryptographically sign the “evidence package manifest” for each decision.
* Optional transparency log anchoring (public Rekor or private equivalent). ([Sigstore][8])
**Evidence required:**
* Object store digest list and integrity proofs.
* Signed manifest (DSSE envelope recommended to bind payload type). ([GitHub][7])
* Inclusion proof or anchor reference if using a transparency log. ([Sigstore][8])
---
### T‑3: Repudiation of decisions or approvals (STRIDE: R)
**Scenario:**
A policy author or approver claims they did not approve a policy change or a high-risk exception.
**Impact:**
Weak governance; cannot establish accountability.
**Controls (shall):**
* Two-person approval workflow for policy changes and exceptions.
* Immutable audit logs capturing: identity, time, action, object, outcome (aligned with audit record content expectations). ([NIST Computer Security Resource Center][4])
* Sign policy versions and exception artifacts.
**Evidence required:**
* Signed policy version artifacts.
* Approval records linked to identity provider logs.
* Change diff + rationale.
---
### T‑4: Information disclosure via SBOM/VEX outputs (STRIDE: I)
**Scenario:**
An auditor-facing export inadvertently reveals proprietary component lists, internal repo URLs, or sensitive dependency relationships.
**Impact:**
Confidentiality breach; contractual/regulatory exposure; risk of targeted exploitation.
**Controls (shall):**
* Role-based access control for evidence and exports.
* Redaction profiles (“regulator view,” “customer view,” “internal view”) with deterministic transformation rules.
* Separate encryption domains (tenant-specific keys).
* Secure export channels; optional offline export bundles for air-gapped review.
**Evidence required:**
* Access-control policy snapshots and enforcement logs.
* Export redaction policy version and redaction transformation log.
---
### T‑5: Denial of service against evaluation pipeline (STRIDE: D)
**Scenario:**
A malicious party floods ingestion endpoints or submits pathological SBOM graphs causing excessive compute and preventing timely decisions.
**Impact:**
Availability and timeliness failures; missed gates/releases.
**Controls (shall):**
* Input size limits, graph complexity limits, and bounded parsing.
* Quotas and rate limiting (per tenant or per submitter).
* Separate async pipeline for heavy analysis; protect decision critical path.
**Evidence required:**
* Rate limit logs and rejection metrics.
* Capacity monitoring evidence (for availability obligations).
---
### T‑6: Elevation of privilege to policy/admin plane (STRIDE: E)
**Scenario:**
An attacker compromises a service account and gains ability to modify policy, disable controls, or access evidence across tenants.
**Impact:**
Complete compromise of decision integrity and confidentiality.
**Controls (shall):**
* Strict separation of duties: policy authoring vs execution vs auditing.
* Least privilege IAM for services (scoped tokens; short-lived credentials).
* Strong hardening of signing key boundary (KMS/HSM boundary; key usage constrained by attestation policy).
**Evidence required:**
* IAM policy snapshots and access review logs.
* Key management logs (rotation, access, signing operations).
---
### T‑7: Supply-chain compromise of artifacts being evaluated (SLSA A–I)
**Scenario:**
The software under evaluation is compromised via source manipulation, build pipeline compromise, dependency compromise, or distribution channel compromise.
**Impact:**
Customer receives malicious/vulnerable software; Platform may miss it without sufficient provenance and identity proofs.
**Controls (should / shall depending on assurance target):**
* Require/provide provenance attestations and verify them against expectations (SLSA-style verification). ([SLSA][5])
* Verify artifact identity by digest and signed provenance.
* Enforce policy constraints for “minimum acceptable provenance” for high-criticality deployments.
**Evidence required:**
* Verified provenance statement(s) (in‑toto compatible) describing how artifacts were produced. ([in-toto][6])
* Build and publication step attestations, with cryptographic binding to artifact digests.
* Evidence of expectation configuration and verification outcomes (SLSA “verification threats” include tampering with expectations). ([SLSA][5])
---
### T‑8: Vulnerability intelligence poisoning / drift
**Scenario:**
The Platform’s vulnerability feed is manipulated or changes over time such that a past decision cannot be reproduced.
**Impact:**
Regulator cannot validate basis of decision at time-of-decision; inconsistent results over time.
**Controls (shall):**
* Snapshot all external intelligence inputs used in an evaluation (source + version + timestamp + digest).
* In offline mode, use curated signed feed bundles and record their hashes.
* Maintain deterministic evaluation by tying each decision to the exact dataset snapshot.
**Evidence required:**
* Feed snapshot manifest (hashes, source identifiers, effective date range).
* Verification record of feed authenticity (signature or trust chain).
(OSV schema design, for example, emphasizes mapping to precise versions/commits; this supports deterministic matching when captured correctly.) ([OSV.dev][13])
---
## 6. Evidence Model
### 6.1 Evidence principles (regulator-grade properties)
All evidence objects in the Platform **shall** satisfy:
1. **Integrity:** Evidence cannot be modified without detection (hashing + immutability).
2. **Authenticity:** Evidence is attributable to its source (signatures, verified identity).
3. **Traceability:** Decisions link to specific input artifacts and transformation steps.
4. **Reproducibility:** A decision can be replayed deterministically given the same inputs and dataset snapshots.
5. **Non‑repudiation:** Critical actions (policy updates, exceptions, decision signing) are attributable and auditable.
6. **Confidentiality:** Sensitive evidence is access-controlled and export-redactable.
7. **Completeness with “Known Unknowns”:** The Platform explicitly records unknown or unresolved data elements rather than silently dropping them.
### 6.2 Evidence object taxonomy
The Platform should model evidence as a graph of typed objects.
**E‑1: Input artifact evidence**
* SBOM documents (SPDX/CycloneDX), including dependency relationships and identifiers.
* VEX documents (CSAF VEX, OpenVEX, CycloneDX VEX) with vulnerability status assertions.
* Provenance/attestations (SLSA-style provenance, in‑toto statements). ([SLSA][14])
* Scan outputs (SCA, container/image scans, static/dynamic analysis outputs).
**E‑2: Normalization and resolution evidence**
* Parsing/validation logs (schema validation results; warnings).
* Canonical “component graph” and “vulnerability mapping” artifacts.
* Identity resolution records: how name/version/IDs were mapped.
**E‑3: Analysis evidence**
* Vulnerability match outputs (CVE/OSV IDs, version ranges, scoring).
* Reachability artifacts (if supported): call graph results, dependency path proofs, or “not reachable” justification artifacts.
* Diff artifacts: changes between SBOM versions (component added/removed/upgraded; license changes; vulnerability deltas).
**E‑4: Policy and governance evidence**
* Policy definitions and versions (rules, thresholds).
* Exception records with approver identity and rationale.
* Approval workflow records and change control logs.
**E‑5: Decision evidence**
* Decision outcome (e.g., pass/fail/risk tier).
* Deterministic decision trace (which rules fired, which inputs were used).
* Unknowns/assumptions list.
* Signed decision statement + manifest of linked evidence objects.
**E‑6: Operational security evidence**
* Authentication/authorization logs.
* Key management and signing logs.
* Evidence store integrity monitoring logs.
* Incident response records (if applicable).
### 6.3 Common metadata schema (minimum required fields)
Every evidence object **shall** include at least:
* **EvidenceID:** content-addressable ID (e.g., SHA‑256 digest of canonical bytes).
* **EvidenceType:** enumerated type (SBOM, VEX, Provenance, ScanResult, Policy, Decision, etc.).
* **Producer:** tool/system identity that generated the evidence (name, version).
* **Timestamp:** time created + time ingested (with time source information).
* **Subject:** the software artifact(s) the evidence applies to (artifact digest(s), package IDs).
* **Chain links:** parent EvidenceIDs (inputs/precedents).
* **Tenant / confidentiality labels:** access classification and redaction profile applicability.
This aligns with the SBOM minimum elements emphasis on baseline data, automation support, and practices/processes including known unknowns and access control.
### 6.4 Evidence integrity and signing
**6.4.1 Hashing and immutability**
* Raw evidence artifacts shall be stored as immutable blobs.
* Derived evidence shall be stored as separate immutable blobs.
* The evidence index shall be append-only and reference blobs by hash.
**6.4.2 Signed envelopes and type binding**
* For high-assurance use, the Platform shall sign:
* Decision statements,
* Per-decision evidence manifests,
* Policy versions and exception approvals.
* Use a signing format that binds the **payload type** to the signature to reduce confusion attacks; DSSE is explicitly designed to authenticate both message and type. ([GitHub][7])
**6.4.3 Attestation model**
* Use in‑toto-compatible statements to standardize subjects (artifact digests) and predicates (decision, SBOM, provenance). ([in-toto][6])
* CycloneDX explicitly recognizes an official predicate type for BOM attestations, which can be leveraged for standardized evidence typing. ([CycloneDX][15])
**6.4.4 Transparency anchoring (optional but strong for regulators)**
* Publish signed decision manifests to a transparency log to provide additional tamper-evidence and public verifiability (or use a private transparency log for sensitive contexts). Rekor is Sigstore’s signature transparency log service. ([Sigstore][8])
### 6.5 Evidence for VEX and “not affected” assertions
Because VEX is specifically intended to prevent wasted effort on non-exploitable upstream vulnerabilities and is machine-readable for automation, the Platform must treat VEX as first-class evidence.
Minimum required behaviors:
* Maintain the original VEX document and signature (if present).
* Track the VEX **status** (not affected / affected / fixed / under investigation) for each vulnerability–product association.
* If the Platform generates VEX-like conclusions (e.g., “not affected” based on reachability), it shall:
* Record the analytical basis as evidence (reachability proof, configuration assumptions),
* Mark the assertion as Platform-authored (not vendor-authored),
* Provide an explicit confidence level and unknowns.
For CSAF-based VEX documents, the Platform should validate conformance to the CSAF VEX profile requirements. ([OASIS Documents][11])
### 6.6 Reproducibility and determinism controls
Each decision must be reproducible. Therefore each decision record **shall** include:
* **Algorithm version** (policy engine + scoring logic version).
* **Policy version** and policy hash.
* **All inputs by digest** (SBOM/VEX/provenance/scan outputs).
* **External dataset snapshot identifiers** (vulnerability DB snapshot digest(s), advisory feeds, scoring inputs).
* **Execution environment ID** (runtime build of the Platform component that evaluated).
* **Determinism proof fields** (e.g., “random seed = fixed/none”, stable sort order used, canonicalization rules used).
This supports regulator expectations for traceability and for consistent evaluation in supply-chain risk management programs. ([NIST Computer Security Resource Center][3])
### 6.7 Retention, legal hold, and audit packaging
**Retention (shall):**
* Evidence packages supporting released decisions must be retained for a defined minimum period (set by sector/regulator/contract), with:
* Immutable storage and integrity monitoring,
* Controlled deletion only through approved retention workflows,
* Legal hold support.
**Audit package export (shall):**
For any decision, the Platform must be able to export an “Audit Package” containing:
1. **Decision statement** (signed)
2. **Evidence manifest** (signed) listing all evidence objects by hash
3. **Inputs** (SBOM/VEX/provenance/etc.) or references to controlled-access retrieval
4. **Transformation chain** (normalization and mapping records)
5. **Policy version and evaluation trace**
6. **External dataset snapshot manifests**
7. **Access-control and integrity verification records** (to prove custody)
---
## 7. Threat-to-Evidence Traceability (Minimal Regulator View)
This section provides a compact mapping from key threat classes to the evidence that must exist to satisfy audit and non-repudiation expectations.
| Threat Class | Primary Risk | “Must-have” Evidence Outputs |
| -------------------------------- | ------------------------------- | ------------------------------------------------------------------------------------------------- |
| Spoofing submitter | Untrusted artifacts used | Auth logs + signature verification + artifact digests |
| Tampering with evidence | Retroactive manipulation | Content-addressed evidence + append-only index + signed manifest (+ optional transparency anchor) |
| Repudiation | Denial of approval/changes | Signed policy + approval workflow logs + immutable audit trail |
| Information disclosure | Sensitive SBOM leakage | Access-control evidence + redaction policy version + export logs |
| DoS | Missed gates / delayed response | Rate limiting logs + capacity metrics + bounded parsing evidence |
| Privilege escalation | Policy/evidence compromise | IAM snapshots + key access logs + segregation-of-duty records |
| Supply-chain pipeline compromise | Malicious artifact | Provenance attestations + verification results + artifact digest binding |
| Vulnerability feed drift | Non-reproducible decisions | Feed snapshot manifests + digests + authenticity verification |
(Where the threat concerns the wider software supply chain, SLSA’s threat taxonomy provides an established clustering for where pipeline threats occur and the role of verification. ([SLSA][5]))
---
## 8. Governance, Control Testing, and Continuous Compliance
To be regulator-grade, the Platform’s security and evidence integrity controls must be governed and tested.
### 8.1 Governance expectations
* Maintain a control mapping to a recognized catalog (e.g., NIST SP 800‑53) for access control, auditing, integrity, and supply-chain risk management. ([NIST Computer Security Resource Center][4])
* Maintain a supply-chain risk posture aligned with C‑SCRM guidance (e.g., NIST SP 800‑161 Rev.1). ([NIST Computer Security Resource Center][3])
* Align secure development practices to SSDF expectations and terminology, noting SSDF has an active Rev.1 IPD (v1.2) publication process at NIST. ([NIST Computer Security Resource Center][2])
### 8.2 Control testing (shall)
At minimum, perform and retain evidence of:
* Periodic integrity tests of evidence store immutability and hash verification.
* Key management audits (signing operations, rotation, restricted usage).
* Access review audits (especially multi-tenant isolation).
* Reproducibility tests: re-run evaluation from historical evidence package and confirm identical results.
---
## Appendix A: Example Signed Decision Statement Structure (Conceptual)
This is a conceptual structure (not a normative schema) showing the minimum linkage needed:
* **Subject:** artifact digest(s) + identifiers
* **Predicate type:** `.../decision` (Platform-defined)
* **Predicate:** decision outcome + rationale + policy hash + dataset snapshot hashes
* **Envelope:** DSSE signature with payload type binding ([GitHub][7])
* **Optional transparency anchor:** Rekor entry UUID / inclusion proof ([Sigstore][8])
---
## Appendix B: Practical Notes for SBOM/VEX Interoperability
* Support both SPDX and CycloneDX ingestion and preservation; both are referenced in SBOM minimum elements discussion and are widely used.
* Treat CSAF VEX and OpenVEX as acceptable VEX carriers; validate schema and preserve original artifacts. ([OASIS Documents][11])
* Capture “known unknowns” explicitly rather than forcing false precision; this is part of SBOM minimum elements’ practices/processes framing and is directly relevant to regulator-grade audit transparency.
---
## What you can do next with this model
If you want, I can produce any of the following artifacts derived directly from this model (without changing its underlying assertions):
1. A **control-to-evidence crosswalk** (NIST 800‑53 / SSDF / C‑SCRM oriented).
2. A **test plan** (control testing, evidence integrity validation, reproducibility drills).
3. A **formal evidence schema** (JSON schema for evidence objects + DSSE envelopes + manifest format).
4. A **regulator-ready “Audit Package” template** you can hand to third parties (including redaction tiers).

# Competitive Benchmark Implementation Milestones
> Source: `docs/product-advisories/19-Dec-2025 - Benchmarking Container Scanners Against Stella Ops.md`
>
> This document translates the competitive matrix into concrete implementation milestones with measurable acceptance criteria.
---
## Executive Summary
The competitive analysis identifies **seven structural gaps** in existing container security tools (Trivy, Syft/Grype, Snyk, Prisma, Aqua, Anchore) that Stella Ops can exploit:

## Milestone 7: Unknowns as First-Class State (UNK)
**Goal:** Explicit unknowns modeling with risk implications.
### Deliverables
| ID | Deliverable | Sprint | Status |
|----|-------------|--------|--------|
| UNK-001 | Unknown-reachable and unknown-unreachable states | 3500 | DONE |
| UNK-002 | Unknowns pressure in scoring | 3500 | DONE |
| UNK-003 | Unknowns registry and API | 3500 | DONE |
| UNK-004 | UI unknowns chips and triage actions | 4100 | TODO |
| UNK-005 | Zero-day window tracking | TBD | TODO |
### Acceptance Criteria
- [ ] Unknowns are distinct from vulnerabilities
- [ ] Scoring reflects unknowns pressure
- [ ] UI surfaces unknowns prominently
- [ ] Air-gap and zero-day scenarios handled
### Competitive Edge
> "No competitor models uncertainty explicitly."
---
## Milestone 8: Epistemic Offline (E-OFF)
**Goal:** Offline = cryptographically bound knowledge state.
### Deliverables
| ID | Deliverable | Sprint | Status |
|----|-------------|--------|--------|
| E-OFF-001 | Feed snapshot with digest | Existing | DONE |
| E-OFF-002 | Policy snapshot with digest | Existing | DONE |
| E-OFF-003 | Scoring rules snapshot | TBD | TODO |
| E-OFF-004 | Trust anchor snapshot | Existing | DONE |
| E-OFF-005 | Knowledge state attestation in scan result | 3500 | DONE |
### Acceptance Criteria
- [ ] Every offline scan knows exactly what knowledge it had
- [ ] Forensic replayability, not just offline execution
- [ ] Audit can answer: "what did you know when you made this decision?"
### Competitive Edge
> "Epistemic completeness vs. just operational offline."

# Sprint 5000.0001.0001 · Advisory Architecture Alignment
## Topic & Scope
- Align StellaOps with the CycloneDX 1.7 / VEX-first / in-toto advisory architecture
- Upgrade CycloneDX from 1.6 to 1.7
- Create comprehensive mapping documentation between advisory signal contracts and StellaOps implementations
- Clarify EPSS terminology and versioning
- Deliver operator evidence proving architectural alignment
**Sprint ID:** SPRINT_5000_0001_0001
**Implementation Plan:** Advisory Architecture Compliance
**Phase:** Phase 0 - Foundation/Documentation
**Priority:** P2 (Alignment/Documentation)
**Estimated Effort:** 3-5 days
**Working Directory:** `src/Scanner/` (code changes), `docs/architecture/` (documentation)
**Dependencies:** None (improvement/alignment work)
---
## Dependencies & Concurrency
- **Depends on:** None - standalone alignment work
- **Blocking:** None - non-breaking enhancements
- **Safe to parallelize with:** All other sprints (documentation + minor version upgrade)
## Documentation Prerequisites
- Advisory document provided (CycloneDX 1.7, VEX-first, in-toto architecture)
- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
- `docs/modules/scanner/architecture.md`
- `docs/modules/excititor/architecture.md`
- `docs/modules/attestor/transparency.md`
---
## Overview
This sprint addresses architectural alignment between StellaOps and the reference advisory architecture that specifies:
- CycloneDX 1.7 as the baseline SBOM envelope
- DSSE-signed in-toto attestations
- VEX-first decisioning with multi-source aggregation
- Signal-based message contracts (Signals 10/12/14/16/18)
- Deterministic scoring with CVSS v4 + EPSS
- Reachability analysis with call-stack witnesses
- Smart-diff and unknowns handling
### Current State Analysis
**Alignment Score: 90%**
✅ **Fully Aligned (18/19 requirements):**
- DSSE signing and in-toto attestations (19 predicate types)
- VEX multi-format support (OpenVEX, CycloneDX VEX, CSAF)
- CVSS v4.0 with MacroVector
- EPSS integration (model_date tracking)
- Deterministic scoring (3 engines)
- Reachability analysis (hybrid static/dynamic)
- Call-stack witnesses (DSSE-signed PathWitness)
- Smart-diff (4 detection rules)
- Unknowns handling (11 types, 5-dimensional scoring)
- Idempotency mechanisms
- Evidence storage (CAS + PostgreSQL)
- Explainability (reason codes + lattice)
- Air-gap support
- Sigstore Rekor integration
⚠️ **Minor Gaps (3):**
1. **CycloneDX Version:** Currently 1.6, advisory requires 1.7
2. **EPSS Terminology:** Uses model_date (correct), advisory says "v4" (clarification needed)
3. **Signal Naming:** Uses domain-specific names vs. generic Signal-10/12/14/16/18
### Goals
1. **Upgrade CycloneDX to 1.7** - Update NuGet packages and code references
2. **Create Signal Mapping Document** - Map advisory signals to StellaOps entities
3. **Clarify EPSS Terminology** - Document model_date vs. version number
4. **Validate Alignment** - Produce evidence of compliance
### Non-Goals
- Re-architecting existing systems (already compliant)
- Changing entity names to match advisory (maintain StellaOps domain language)
- Breaking API changes

---
## Decisions & Risks
### Decisions
1. **Preserve StellaOps Domain Language**
- Decision: Keep existing entity names (TriageFinding, EventEnvelope, etc.)
- Rationale: Domain-specific names are more meaningful than generic Signal-X labels
- Impact: Create mapping documentation instead of renaming
2. **CycloneDX 1.7 Upgrade Path**
- Decision: Upgrade directly to latest CycloneDX.Core version supporting 1.7
- Rationale: Backward compatible, minimal breaking changes
- Impact: 1-2 day effort, low risk
3. **EPSS Terminology Approach**
- Decision: Document clarification, no code changes
- Rationale: StellaOps implementation is correct per FIRST.org spec
- Impact: Documentation update only
### Risks
| Risk | Likelihood | Impact | Mitigation |
|------|-----------|--------|------------|
| CycloneDX 1.7 spec not yet supported by CycloneDX.Core | Medium | Medium | Check GitHub releases; if unavailable, track issue and plan upgrade when available |
| Breaking changes in 1.6 → 1.7 spec | Low | Low | Review spec changelog; CycloneDX maintains backward compatibility |
| Test failures after upgrade | Low | Medium | Comprehensive test suite; rollback plan if needed |
| Documentation review delays | Low | Low | Self-contained documentation; can merge incrementally |
---
## Testing Strategy
### Unit Tests
- Scanner.Emit.Tests: CycloneDX composer tests
- Verify spec version in output JSON
- Validate media type headers
### Integration Tests
- Generate SBOM from sample container image
- Validate against CycloneDX 1.7 JSON schema
- Verify protobuf serialization
- Test backward compatibility with 1.6 consumers
### Validation Tests
- Schema validation: `npm run api:lint`
- SBOM validation: External CycloneDX validator
- Signature verification: DSSE envelope validation

## Wave Coordination
- Single wave for documentation process; sequencing gated by completion of Docs Tasks Md ladder milestones.
## Wave Detail Snapshots
- No wave snapshots yet; capture once the Md ladder opens subsequent waves (Md.II onward).
## Interlocks
- BLOCKED tasks must be traced via `BLOCKED_DEPENDENCY_TREE.md` before work starts.
- Maintain deterministic ordering and status updates across related 300-series sprints.

## Decisions & Risks
| Item | Type | Owner(s) | Due | Notes |
| --- | --- | --- | --- | --- |
| Confirm sequencing gates between Md.I and module dossiers | Decision | Docs Guild · Module guild leads | 2025-11-18 | Needed before opening 312–335 sprints. |
| Docs capacity constrained while Md.I remains open | Risk | Docs Guild | Ongoing | Track velocity; request backup writers if Md.I exceeds 2-week window. |
## Next Checkpoints
| Date (UTC) | Session | Goal | Owner(s) |
| --- | --- | --- | --- |

# Sprint 0303 · Documentation & Process · Docs Tasks Md III
## Topic & Scope
- Phase Md.III of the docs ladder: console observability/forensics docs and exception-handling doc set.
- Keep outputs deterministic (hash-listed fixtures, reproducible captures) and ready for offline packaging.
- **Working directory:** `docs/` (module guides, governance, console docs; any fixtures under `docs/assets/**`).
## Dependencies & Concurrency
- Upstream deps: Sprint 200.A Docs Tasks Md.II hand-off; Console observability UX assets and deterministic sample data; Governance/Exceptions contracts and routing matrix; Exception API definitions.
- Concurrency: Later Md phases (304–309) remain queued; avoid back edges. Coordinate with console/exception feature sprints but keep doc scope self-contained.
## Documentation Prerequisites
- `docs/README.md`
- `docs/modules/platform/architecture-overview.md`
- `docs/AGENTS.md` (docs working agreement)
- Console module dossier for observability widgets (when provided)
- Governance/Exceptions specifications (when provided)

| 2025-12-04 | Added deterministic stubs for DOCS-CONSOLE-OBS-52-001 (`docs/console/observability.md`) and DOCS-CONSOLE-OBS-52-002 (`docs/console/forensics.md`) to lock outline and determinism checklist while awaiting assets/hashes; tasks remain BLOCKED. | Docs Guild |
| 2025-12-04 | Added `docs/console/SHA256SUMS` placeholder to record hashes once console captures/payloads arrive; keeps determinism workflow ready. | Docs Guild |
| 2025-12-05 | Recorded stub hash entries in `docs/console/SHA256SUMS` for observability/forensics outlines; replace with real asset hashes when provided. Tasks stay BLOCKED. | Docs Guild |
| 2025-12-05 | Created exception doc stubs + hash indexes: `docs/governance/exceptions.md`, `docs/governance/approvals-and-routing.md`, `docs/api/exceptions.md`, `docs/ui/exception-center.md`, `docs/modules/cli/guides/exceptions.md` with SHA256SUMS placeholders. Tasks remain BLOCKED pending contracts/assets. | Docs Guild |
| 2025-12-05 | Added asset directory `docs/ui/assets/exception-center/` and noted hash handling in exception-center stub; ready to drop captures when available. | Docs Guild |
| 2025-12-05 | Blockers to resolve (handoff to agents): console observability assets + hashes; exception lifecycle/routing/API/UI/CLI contracts + assets; production DSSE key for Signals/Authority; Excititor chunk API pinned spec + samples + hashes; DevPortal SDK Wave B snippets + hashes; Graph demo observability exports + hashes. | Project Mgmt |
| 2025-12-06 | Added authority routing decision contract: `docs/contracts/authority-routing-decision.md` (DECISION-AUTH-001) establishes RBAC-standard claim routing; provides contract for DOCS-EXC-25-002 approvals/routing documentation. | Project Mgmt |
| 2025-12-05 | Normalised sprint header to standard template; no status changes. | Project Mgmt |
## Decisions & Risks
### Decisions
| Decision | Owner(s) | Due | Notes |
| --- | --- | --- | --- |
| Md.III scope fixed to console observability/forensics plus exceptions documentation chain; avoid adding new module docs until blockers clear. | Docs Guild | 2025-11-18 | Reaffirmed while importing backlog from Md.II. |
### Risks
| Risk | Impact | Mitigation |
| --- | --- | --- |
| Console observability assets (widgets, sample data, hash list) not yet delivered. | Blocks DOCS-CONSOLE-OBS-52-001/002; delays console doc set. | Request asset drop + hashes from Console Guild; outlines/stubs now in repo to reduce rework; keep BLOCKED until fixtures arrive. |
| Exception governance contract & routing matrix outstanding. | Blocks DOCS-EXC-25-001..006 chain; downstream CLI/UI/API docs stalled. | Ask Governance/Authority/Platform guilds for contract + API draft; keep tasks BLOCKED and mirror in `BLOCKED_DEPENDENCY_TREE.md` if escalated. |
## Next Checkpoints
| Date (UTC) | Session | Goal | Owner(s) |
| --- | --- | --- | --- |
| TBD | Console observability asset drop | Deliver deterministic widget captures + sample payload hashes to unblock DOCS-CONSOLE-OBS-52-001/002. | Console Guild · Docs Guild |
| TBD | Exceptions contract hand-off | Provide lifecycle/routing matrix + API contract to unblock DOCS-EXC-25-001..006. | Governance Guild · Authority Core · BE-Base Platform |

## Wave Coordination
- Single wave; policy studio tasks (11–15) remain blocked until upstream delivery.
## Wave Detail Snapshots
- None captured; add when policy studio inputs land.
## Interlocks
- BLOCKED items must trace via `BLOCKED_DEPENDENCY_TREE.md` before work resumes.
- Mirror status flips to `tasks-all.md` for determinism.

# Sprint 0308 · Documentation & Process · Docs Tasks Md.VIII
## Topic & Scope
- Advance the Docs Tasks ladder (Md.VIII) for the policy stack: promotion, CLI, API, attestations, registry architecture, telemetry, incident/runbook, templates, and AOC guardrails.
- Launch the risk documentation chain (overview → profiles → factors → formulas → explainability → API) with deterministic, offline-friendly examples.
- Keep outputs reproducible (fixed fixtures, ordered tables) and align hand-offs between Md.VII inputs and Md.IX expectations.
- **Working directory:** `docs/` (policy and risk subtrees; sprint planning remains in `docs/implplan/`).
## Dependencies & Concurrency
- Upstream: Sprint 200.A - Docs Tasks.Md.VII; DOCS-POLICY-27-005 completion; registry schema/telemetry inputs; risk engine/API schemas.
- Downstream: Sprint 0309 (Md.IX) expects promotion/CLI/API drafts; avoid back-edges from this file to later phases.
- Concurrency rules: Policy chain is strictly sequential (27-006 → 27-014). Risk chain is sequential (66-001 → 67-002). Work in order; do not parallelize without upstream evidence.
## Documentation Prerequisites
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/policy/architecture.md
- docs/implplan/BLOCKED_DEPENDENCY_TREE.md
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review `docs/implplan/BLOCKED_DEPENDENCY_TREE.md` for root blockers and dependencies.

- None yet. Add summaries per wave if/when staged deliveries are planned.
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-12-05 | Normalised sprint to standard template; clarified header and moved interlocks into Decisions & Risks; no task status changes. | Project Mgmt |
| 2025-12-05 | DOCS-RISK-66-001..004 and DOCS-RISK-67-001/002 delivered with schema-aligned fixtures and explainability API examples; statuses set to DONE. | Docs Guild |
## Decisions & Risks
- **Risk:** Policy chain (DOCS-POLICY-27-006..014) blocked pending DOCS-POLICY-27-005 outputs and registry schema approvals (`docs/schemas/api-baseline.schema.json` alignment). Mitigation: keep BLOCKED; request registry draft + policy studio sign-off.
- **Risk:** Need policy studio/editor assets to unblock CLI/API/attestation docs; track via 27-006 dependencies.
- **Decision:** Risk documentation chain (66-001..67-002) marked complete with deterministic samples; future schema changes require revisiting hashes and fixtures.
## Next Checkpoints
- 2025-12-12 · Policy docs sync (tentative): confirm delivery dates for 27-006 → 27-010 chain and registry schemas. Owners: Docs Guild · Policy/Registry Guilds.
- 2025-12-15 · Risk docs readiness check: validate whether further schema/API changes require doc refresh. Owners: Docs Guild · Risk Engine Guild.
| Confirm DOCS-POLICY-27-005 completion signal | Policy Guild | 2025-12-11 | OPEN |

| Pre-scaffold explainability/api outlines (67-001/002) | Docs Guild | 2025-12-15 | DONE (2025-12-05) |
| Reconcile legacy `docs/risk/risk-profiles.md` into new schema-aligned outline | Docs Guild | 2025-12-15 | DONE (2025-12-05) |
| Prepare deterministic sample layout under `docs/risk/samples/` | Docs Guild | 2025-12-15 | DONE (2025-12-05) |
| Capture registry schema alignment signal and flip 27-008 when ready | Policy Registry Guild → Docs Guild | 2025-12-12 | PENDING |
| Capture PLLG0104 risk schema/payload signal and flip 66-001/002 when ready | PLLG0104 → Docs Guild | 2025-12-13 | PENDING |
| Seed SHA manifests for profiles/factors/explain/api samples | Docs Guild | 2025-12-05 | DONE (2025-12-05) |

| Daily signal check (registry schema + PLLG0104 payloads) and log outcome | Docs Guild | 2025-12-13 | DOING (2025-12-05) |
| Capture console/CLI telemetry frames for explainability visuals | Console Guild | 2025-12-15 | DONE (2025-12-05 via fixtures) |
## Decisions & Risks
### Decisions
- CONTRACT-RISK-SCORING-002 (published 2025-12-05) is the canonical schema for risk overview/profiles/factors/formulas; use it for Md.VIII docs until superseded.
- Deterministic fixtures for profiles, factors, explain, and API samples are now canonical references (see `docs/risk/samples/**/SHA256SUMS`).
### Risks
| Risk | Impact | Mitigation |
| --- | --- | --- |
| DOCS-POLICY-27 chain blocked by missing promotion/registry inputs | Entire policy documentation ladder stalls; pushes Md.IX hand-off | Track in BLOCKED_DEPENDENCY_TREE; weekly check-ins with Policy/Registry Guilds; stage scaffolds while waiting. |
| Risk documentation chain lacks real telemetry captures | If fixtures drift from UI, Md.IX readiness slips | Use captured CLI/console fixtures as baseline; refresh with live UI frames when available. |
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |

# Sprint 0309 · Documentation & Process · Docs Tasks Md IX
## Topic & Scope
- Phase Md.IX of the docs ladder, covering risk UI/CLI flows, offline risk bundles, SDK overview/language guides, auth/redaction security docs, and the reachability/signals doc chain (states, callgraphs, runtime facts, weighting, UI overlays, CLI, API).
- Active items only; completed or historic work sits in `docs/implplan/archived/tasks.md` (updated 2025-11-08).
- **Working directory:** `docs/` (module guides, console/CLI/UI/risk/signals docs; assets under `docs/assets/**` as needed).
## Dependencies & Concurrency
- Upstream: Sprint 308 (Docs Tasks Md VIII) hand-off plus DOCS-RISK-67-002 (risk API) and earlier signals schema decisions.
- Concurrency: Later Md phases (310–311) stay queued; coordinate with Console/CLI/UI/Signals guilds for shared assets and schema drops.
## Documentation Prerequisites
- `docs/README.md`
- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
- `docs/modules/platform/architecture-overview.md`
- `docs/AGENTS.md`, `docs/implplan/AGENTS.md`
- **BLOCKED tasks:** review `BLOCKED_DEPENDENCY_TREE.md` before starting items marked as blocked in upstream sprints.

## Wave Coordination
- Single wave for Md.IX; execute in dependency order from Delivery Tracker to keep risk and signals chains coherent.
## Wave Detail Snapshots
- No additional wave snapshots; Delivery Tracker ordering suffices for this single-wave sprint.
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-12-05 | Normalised sprint to standard template; clarified header; moved interlocks into Decisions & Risks; no task status changes. | Project Mgmt |
## Decisions & Risks
- **Decision:** Keep Md.IX scope limited to risk/SDK/security/signals doc set; defer new module docs until upstream assets arrive (Docs Guild, due 2025-12-05).
- **Risk:** DOCS-RISK-67-002 and console assets not yet delivered, blocking DOCS-RISK-67-003/004/68-001/68-002 chain. Mitigation: track in `BLOCKED_DEPENDENCY_TREE.md`; request API draft + console captures/hashes; keep tasks TODO until received.
- **Risk:** Signals chain (DOCS-SIG-26-001..007) depends on schema/asset hand-offs from Signals, UI, and CLI guilds. Mitigation: maintain Action Tracker reminders; do not start without assets.
- **Risk:** SDK deliverable requires generator outputs across four languages; drift risk if guides proceed without samples. Mitigation: block on generator outputs; cross-check hashes on arrival.
## Next Checkpoints
- 2025-12-08 · Md.VIII → Md.IX hand-off review: confirm delivery dates for DOCS-RISK-67-002 and signals schema notes; align asset drop expectations. Owners: Docs Guild · Console Guild · Signals Guild.
- 2025-12-12 · Md.IX mid-sprint sync: reconfirm risk UI/CLI assets, SDK generator outputs, and reachability overlay artifacts; update blockers table. Owners: Docs Guild · CLI Guild · UI Guild · SDK Generator Guild.

# Sprint 0310 · Documentation & Process — Docs Tasks Md.X
## Topic & Scope
- Advance the tenth Docs Tasks wave (Md.X) with tenancy, reachability, scanner surface/bench, and VEX consensus documentation ready for downstream consumers.
- Align doc outputs with upstream implementation sprints (Surface, Tenancy, VEX Lens) and ensure guidance stays deterministic/offline-friendly.
- Evidence expected: published/updated markdown in `docs/**` plus traceable task status in this sprint.
- **Working directory:** `docs/implplan` (coordination) and `docs/` (module and runbook docs referenced in Delivery Tracker).
## Dependencies & Concurrency
- Upstream dependency: Sprint 200.A - Docs Tasks.Md.IX and any blockers listed in `BLOCKED_DEPENDENCY_TREE.md`. Review before moving tasks to DOING.
- Parallel-safe with other docs sprints; maintain deterministic ordering by Task ID when updating tables.
## Documentation Prerequisites
- docs/README.md; docs/07_HIGH_LEVEL_ARCHITECTURE.md; docs/modules/platform/architecture-overview.md.

- Reachability migration: `/docs/migration/enable-reachability.md` — rollout phases, fallback playbook, monitoring hooks placeholders.
- VEX consensus set: `/docs/vex/consensus-overview.md`, `/docs/vex/consensus-algorithm.md`, `/docs/vex/issuer-directory.md`, `/docs/vex/consensus-api.md` — shared front-matter + glossary; stub examples section for PLVL0102 data.
- Scanner surface/bench: `/docs/modules/scanner/scanner-engine.md` and `/docs/modules/scanner/benchmarks/*.md` — frame sections for Surface.FS/Env/Secrets flow, OS coverage, language lockfiles, stripped/entrytrace/SAST enrichers.
- Contract testing: `/docs/testing/contract-testing.md` — outline for mock server, replay fixtures, golden files, determinism guardrails.
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-12-05 | Normalised sprint to standard template; clarified header; moved interlocks into Decisions & Risks; no status changes. | Project Mgmt |
## Decisions & Risks
- **Risk:** Tenancy docs (DOCS-TEN-47/48/49) require DVDO0110 decisions and CLI/env var confirmations; keep DOING with placeholders until ADR lands.
- **Risk:** Reachability migration guide depends on DOCS-SIG-26-007 and notifications hook readiness (058_NOTY0101); keep coordination with Signals/Notify guilds.
- **Risk:** Scanner surface/bench docs depend on analyzer outputs (SCSA0301, SCSA0601), replay hooks (RPRC0101), and CLI samples (132_CLCI0110); leave DOING skeletons until evidence delivered.
- **Risk:** VEX consensus series depends on PLVL0102 schemas, issuer directory inputs, and DevOps rollout plans for signatures/ops; block finalization on schema snapshots and rollout plan.
- **Decision:** Maintain single-wave execution; task ordering follows Delivery Tracker to preserve dependency chain determinism.
## Upcoming Checkpoints
- 2025-12-07 15:00 UTC — 20-min skeleton-sync to align outlines and branch contents across guild writers.
- 2025-12-08 15:00 UTC — daily micro-sync to triage incoming ADR/schema/logs and assign fill-ins.
- 2025-12-09 15:00 UTC — dependency check-in with Security, DevOps, VEX, Surface guilds (confirm DVDO0110, PLVL0102, SCANNER-SURFACE-04 readiness).
## Action Tracker
| Action | Owner | Due (UTC) | Status | Notes |
| --- | --- | --- | --- | --- |

| Commit & push branch `feature/docs-mdx-skeletons` once credentials/hook window available | Docs Guild | 2025-12-06 | PLANNED | Local commit/push pending; staging is ready. |
## Decisions & Risks
| Risk | Impact | Mitigation | Owner |
| --- | --- | --- | --- |
| Upstream dependencies (DVDO0110, DOCS-SIG-26-007, analyzer outputs) slip | Doc set misses release window or ships with gaps | Track blockers via `BLOCKED_DEPENDENCY_TREE.md`, gate DOING until inputs land, use interim placeholders only with explicit notes | Docs Guild |
| Cross-module docs drift in style/terminology | Increased review churn and inconsistent guidance | Align with module dossiers and shared glossary; peer review across guilds before marking tasks DONE | Docs Guild |
| Filename change from legacy sprint reference | References could break in aggregators | Replace references in aggregators; note rename in Execution Log | Project management |

# Sprint 0311 · Documentation & Process · Docs Tasks Md.XI
## Topic & Scope
- Phase Md.XI of the docs ladder covering Vuln Explorer + Findings Ledger: overview, console, API, CLI, ledger, policy, VEX, advisories, SBOM, observability, security, ops, and install guides.
- Deliver offline/deterministic artifacts (hash manifests for captures and payloads) aligned with Vuln Explorer and Findings Ledger schemas.
- **Working directory:** `docs/` (Vuln Explorer + Findings Ledger docs; fixtures/assets under `docs/assets/vuln-explorer/**`). Active items only; completed work lives in `docs/implplan/archived/tasks.md` (updated 2025-11-08).
## Dependencies & Concurrency
- Upstream: Md.X hand-off (SPRINT_0310_0001_0010_docs_tasks_md_x) plus Vuln Explorer GRAP0101 contract and Findings Ledger replay/Merkle notes.
- Concurrency: coordinate UI/CLI/Policy/DevOps asset drops; avoid back edges to Md.VIII/IX risk ladders and reachability doc sprints.
- BLOCKED tasks must mirror `BLOCKED_DEPENDENCY_TREE.md` before movement.
## Documentation Prerequisites
- `docs/README.md`
- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
- `docs/modules/platform/architecture-overview.md`

| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-12-05 | Normalised sprint to standard template; clarified header; moved interlocks into Decisions & Risks; no status changes. | Project Mgmt |
## Decisions & Risks
- **Risk:** UI/CLI asset drops required for console and CLI guides (#2–#4); keep TODO until assets with hashes arrive.
- **Risk:** Policy and DevOps rollout notes needed before publishing determinations and telemetry content (#6, #10); block until signals/simulation semantics and SLOs are provided.
- **Risk:** Export bundle and advisories provenance spec needed for integration doc (#8) and downstream SBOM/install updates; wait for specs before progressing.
- **Decision:** Single-wave execution; tasks follow Delivery Tracker dependency order to keep Vuln Explorer/Findings Ledger chain coherent.

## Decisions & Risks
### Decisions
| Decision | Owner(s) | Due | Notes |
| --- | --- | --- | --- |
| Md.XI scope fixed to Vuln Explorer + Findings Ledger doc chain; no new module docs added this wave. | Docs Guild | 2025-12-05 | Keeps ladder narrow and preserves dependency ordering. |
### Risks
| Risk | Impact | Mitigation |
| --- | --- | --- |
| Console/API/CLI assets arrive late. | Delays tasks #2–#4 and downstream chain (#5–#13). | Request early text stubs and payload samples; keep tasks TODO until hashes captured. |
| Export bundle and advisories provenance spec not delivered. | Blocks task #8 and downstream SBOM/observability/install docs. | Track in Action Tracker; mirror blocker in `BLOCKED_DEPENDENCY_TREE.md` if slip past 2025-12-12. |
| Policy/DevOps semantics churn. | Rework across tasks #6 and #10–#12. | Hold publish until 2025-12-16 sync; capture versioned assumptions in doc footers. |
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-12-05 | Normalised sprint to docs/implplan template; renamed file to `SPRINT_0311_0001_0001_docs_tasks_md_xi.md`; no task status changes. | Project Mgmt |

| 2025-12-05 | Added escalation action for GRAP0101 delay (due 2025-12-09) to avoid idle time; no status changes. | Docs Guild |
| 2025-12-05 | Added GRAP0101 integration checklist `docs/vuln/GRAP0101-integration-checklist.md` to speed field propagation across Md.XI stubs once contract arrives. | Docs Guild |
| 2025-12-05 | Prefilled `docs/assets/vuln-explorer/SHA256SUMS` with placeholders for expected assets to reduce turnaround when hashes land. | Docs Guild |
| 2025-12-06 | ✅ GRAP0101 contract created at `docs/schemas/vuln-explorer.schema.json` — 13 Md.XI tasks unblocked; domain models (VulnSummary, VulnDetail, FindingProjection, TimelineEntry) now available for integration. Action tracker item marked DONE. | System |

## Decisions & Risks
- Offline posture must be preserved; dashboards stay JSON importable (no external datasources).
- Tenant-scope/Surface.Env/Surface.Secrets contracts must stay aligned with platform docs; update sprint/TASKS if they change.
- Keep sprint and TASKS mirrored to avoid drift.
- Rekor receipt schema/catalog changes (RR1–RR10) must be signed and mirrored in Authority/Sbomer; artefacts drafted and hashed (see `gaps/`), DSSE signing still pending once Authority key is available.
- AU1–AU10 artefacts drafted and hashed; DSSE signing pending. Keep SHA256SUMS/DSSE paths stable to avoid drift.
## Next Checkpoints
- 2025-12-05 · Verify grafana-dashboard.json still matches current metrics contract; update runbooks if changes land. Owner: Ops Guild.

# Sprint 0315 · Docs Modules · CI
## Topic & Scope
- Refresh the CI Recipes module docs (AGENTS, README, architecture, implementation plan) so contributors have a current charter and status mirror workflow.
- Stand up a TASKS board for the module and wire sprint references to the normalized filename for traceability.
- Keep guidance deterministic/offline-ready and ensure legacy references to the old sprint filename keep working.
- **Working directory:** `docs/modules/ci`.
## Dependencies & Concurrency
- Upstream context: Attestor 100.A, AdvisoryAI 110.A, AirGap 120.A, Scanner 130.A, Graph 140.A, Orchestrator 150.A, EvidenceLocker 160.A, Notifier 170.A, CLI 180.A, Ops Deployment 190.A.
- No blocking concurrency; documentation-only refresh.
## Documentation Prerequisites
- `docs/modules/ci/README.md`
- `docs/modules/ci/architecture.md`
- `docs/modules/ci/implementation_plan.md`
- `docs/modules/ci/AGENTS.md`
- `docs/modules/platform/architecture-overview.md`

| CI Docs Refresh | Docs Guild · Module Team | Required reading listed above | DONE | Single-pass documentation refresh; no staged waves. |
## Wave Detail Snapshots
- Not applicable (single-wave sprint).
## Interlocks
- Keep CI recipes aligned with offline/air-gap defaults and determinism guardrails documented in platform/architecture guides.
- Legacy sprint filename preserved via stub `SPRINT_315_docs_modules_ci.md` to avoid broken links.
## Upcoming Checkpoints
- None scheduled; schedule next review when CI recipes gain new pipelines.
## Action Tracker
| # | Action | Owner | Due (UTC) | Status |

## Decisions & Risks
- Decision: Sprint file normalized to standard template and renamed to `SPRINT_0315_0001_0001_docs_modules_ci.md`; legacy stub retained for references.
- Decision: TASKS board (`docs/modules/ci/TASKS.md`) is the status mirror alongside this sprint file.
- Risk: Future CI recipe updates could drift if TASKS and sprint file aren’t updated together; mitigated by Action 1.

# Sprint 0327-0001-0001 · Docs Modules Scanner
## Topic & Scope
- Keep scanner module documentation/process in sync with current implementation sprints and readiness gates.
- Capture Windows/macOS analyzer demand signals for product/marketing readiness.
- Fold post-demo runbook/observability feedback into module docs.
- **Working directory:** `docs/implplan` (tracker) with linked updates under `docs/modules/scanner`.
## Dependencies & Concurrency
- Upstream inputs: Sprint 130–139 scanner wave status, ops demo outputs.
- Parallel-safe; avoid changing other modules without noting in Decisions & Risks.
## Documentation Prerequisites
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/scanner/architecture.md
## Delivery Tracker
| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |
| --- | --- | --- | --- | --- | --- |
| 1 | SCANNER-DOCS-0003 | BLOCKED | Waiting on field/sales demand signal interviews to be scheduled; no data available yet. | Docs Guild · Product Guild (`docs/modules/scanner`) | Gather Windows/macOS analyzer demand signals and record findings in `docs/benchmarks/scanner/windows-macos-demand.md` for marketing + product readiness. |
| 2 | SCANNER-OPS-0001 | BLOCKED | Next scanner demo not yet scheduled; need demo output to review runbooks/observability. | Ops Guild (`docs/modules/scanner`) | Review scanner runbooks/observability assets after the next sprint demo and capture findings inline with sprint notes. |
| 3 | SCANNER-ENG-0001 | DONE (2025-12-01) | Keep checkpoints updated when new scanner sprints land. | Module Team (`docs/modules/scanner`) | Cross-check implementation plan milestones against `/docs/implplan/SPRINT_*.md` and update module readiness checkpoints. |
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-12-01 | Normalised sprint to standard template, renamed from `SPRINT_327_docs_modules_scanner.md` to `SPRINT_0327_0001_0001_docs_modules_scanner.md`; legacy stub retained for redirects. | Project Mgmt |
| 2025-12-01 | Completed SCANNER-ENG-0001: created readiness checkpoint doc (`docs/modules/scanner/readiness-checkpoints.md`) summarising sprint 0131–0138 status; linked in Decisions & Risks. | Module Team |
| 2025-12-01 | Marked SCANNER-DOCS-0003 and SCANNER-OPS-0001 BLOCKED awaiting field/demand inputs and the next scanner demo respectively. No work can proceed until upstream signals arrive. | Project Mgmt |
## Decisions & Risks
- Readiness checkpoints show amber/red gaps for Java/.NET analyzers (Sprint 0131) and PHP parity (Sprint 0138); see `docs/modules/scanner/readiness-checkpoints.md`.
- Windows/macOS demand signals (SCANNER-DOCS-0003) not yet captured; risk of marketing misalignment until data gathered.
- Ops feedback pending next demo (SCANNER-OPS-0001); note cross-module doc touch in `docs/modules/scanner` when applied.
- Both BLOCKED tasks depend on external scheduling (field interviews, demo). Revisit after dates confirmed; keep sprint aligned with upstream signals.
## Next Checkpoints
- 2025-12-05: Collect demand-signal inputs from field/PM for SCANNER-DOCS-0003 (owner: Product Guild).
- 2025-12-06: Runbook/observability review after next scanner demo (owner: Ops Guild).

# Sprint 0328 · Docs & Process (Scheduler Module)
## Topic & Scope
- Refresh Scheduler module docs (AGENTS, TASKS) to make the charter actionable for implementers.
- Normalise sprint/task hygiene so status moves mirror AGENTS workflow and main sprint boards.
- Ensure outcomes are synced back to repo-level planning artefacts for traceability.
- **Working directory:** docs/modules/scheduler
## Dependencies & Concurrency
- Upstream: Documentation readiness from Attestor (100.A), AdvisoryAI (110.A), AirGap (120.A), Scanner (130.A), Graph (140.A), Orchestrator (150.A), EvidenceLocker (160.A), Notifier (170.A), CLI (180.A), Ops Deployment (190.A).
- Concurrency: independent of Scheduler implementation sprints 0155/0156; coordination only through referenced docs.
## Documentation Prerequisites
- docs/modules/scheduler/README.md
- docs/modules/scheduler/architecture.md
- docs/modules/scheduler/implementation_plan.md
- docs/modules/scheduler/AGENTS.md (this sprint refreshes it)
## Delivery Tracker
| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |

| --- | --- | --- |
| 2025-11-17 | Normalised sprint to standard template, renamed to `SPRINT_0328_0001_0001_docs_modules_scheduler.md`; set tasks to DOING for refresh work. | Docs Guild |
| 2025-11-17 | Refreshed AGENTS charter, created TASKS.md, and marked tasks DONE; synced statuses to `tasks-all`. | Docs Guild |
## Decisions & Risks
- Keep AGENTS and TASKS as the front door for Scheduler contributors; future contract changes must update both and link back here.
- Must mirror status changes in both this sprint file and `docs/modules/scheduler/TASKS.md` to avoid divergence.
## Next Checkpoints
- None scheduled; set a doc review once AGENTS/TASKS refresh is published.

## Decisions & Risks
- EXCITITOR-DOCS-0001 blocked on chunk API CI validation and OpenAPI freeze; downstream ops/eng tasks stay TODO until resolved. Freeze gate captured in `docs/modules/excititor/OPENAPI_FREEZE_CHECKLIST.md` (CI green, pinned spec, hashed samples).
- Mirror statuses in `docs/modules/excititor/TASKS.md` to avoid drift between sprint and module board.
- Offline posture must be maintained; dashboards should remain importable without external services.
## Next Checkpoints
- 2025-12-05 · Reassess chunk API CI and OpenAPI freeze; if green, unblock EXCITITOR-DOCS-0001 and propagate updates. Owner: Docs Guild.

## Competitive Landscape (Dec 2025)
Based on analysis of Trivy, Syft/Grype, Snyk, Prisma, Aqua, and Anchore:
### Structural Gaps We Exploit
| Capability | Industry Status | Stella Ops Advantage |
|------------|-----------------|---------------------|
| **SBOM Fidelity** | Static artifact, no lineage | Stateful ledger with build provenance |
| **VEX Handling** | Annotation/suppression | Formal lattice reasoning with conflict resolution |
| **Explainability** | UI hints, remediation text | Proof-linked evidence with falsification conditions |
| **Smart-Diff** | File-level/hash comparison | Semantic security meaning diff |
| **Reachability** | "Runtime context" (coarse) | Three-layer call-path proofs |
| **Scoring** | CVSS + proprietary heuristics | Deterministic, attestable, reproducible |
| **Unknowns** | Hidden/suppressed | First-class state with risk implications |
| **Offline** | Operational capability | Epistemic completeness (bound knowledge state) |
### Why Competitors Plateau
1. **Trivy/Syft** grew from package scanners — no forensic reproducibility design
2. **Snyk** grew from developer UX — no attestation/proof infrastructure
3. **Prisma/Aqua** grew from policy/compliance — no deterministic replay
None were designed around **forensic reproducibility or trust algebra**.
### Where We're Stronger
- Deterministic replayable scans
- Formal VEX reasoning
- Reachability-backed exploitability
- Semantic smart-diff
- Evidence-first explainability
- Unknowns modeling
- Jurisdiction-ready offline trust
### Where Competitors Remain Ahead (for now)
- Mass-market UX polish
- SaaS onboarding friction
- Marketplace integrations

## 📌 Key Notes, Gaps & Opportunities (Markdown)
### **SBOM Fidelity**
* **Open tools (Trivy, Syft)** already support CycloneDX/SPDX output, but mostly as flat SBOM artifacts without long‑term repositories or versioned diffing. ([Ox Security][1])
* **Opportunity:** Provide *repository + lineage + merge semantics* with proofs — not just generation.
### **VEX Handling**
* Trivy has an open feature request for dynamic VEX ingestion. ([GitHub][2])
* Most competitors either lack VEX support or have no *decisioning logic* based on exploitability.
* **Opportunity:** First‑class VEX ingestion with evaluation rules + automated scoring.
### **Explainability**
* Commercial tools (Prisma/Snyk) offer UI report context and dev‑oriented remediation guidance. ([Snyk][3])
* OSS tools provide flat scan outputs with minimal causal trace.
* **Opportunity:** Link vulnerability flags back to *proven code paths*, enriched with SBOM + call reachability.
### **Smart‑Diff & Unknowns State**
* No major tool advertising *smart diffing* between SBOMs for incremental risk deltas across releases.
* **Opportunity:** Automate risk deltas between SBOMs with uncertainty margins.
### **Call‑Stack Reachability**
* None of these tools publicly document call‑stack based exploit reachability analysis out‑of‑the‑box.
* **Opportunity:** Integrate dynamic/static reachability evidence that elevates scanning from surface report → *impact map*.
### **Deterministic Scoring**
* Snyk & Prisma offer proprietary scoring that blends severity + context. ([TrustRadius][4])
* But these aren’t reproducible with *signed verdicts*.
* **Opportunity:** Provide *deterministic, attestable scoring proofs*.
### **Ecosystem Integrations**
* Trivy/Grype excel at lightweight CI/CD and Kubernetes. ([Echo][5])
* Enterprise products integrate deeply into cloud/registry. ([Palo Alto Networks][6])
* **Opportunity:** Expand *sigstore/notation* based pipelines and automated attestation flows.
### **Policy Engine**
* Prisma & Aqua have mature enterprise policies. ([Aqua][7])
* OSS tools have limited simple allow/deny.
* **Opportunity:** Provide *lattice/constraint policies* with proof outputs.
### **Offline/Air‑Gapped**
* Anchore supports air‑gapped deployment in enterprise contexts. ([Anchore][8])
* Support across all open tools is ad‑hoc at best.
* **Opportunity:** Built‑in deterministic offline modes with offline SBOM stores and VEX ingestion.
### **Provenance/Attestations**
* Syft supports SBOM output in various formats; also *in‑toto* for attestations. ([Ox Security][1])
* Most competitors don’t prominently advertise *attestation pipelines*.
* **Opportunity:** End‑to‑end DSSE/in‑toto provenance with immutable proofs.
---
### 📌 Public Evidence Links
* **Trivy / Syft / Grype SBOM support & formats:** CycloneDX/SPDX; Syft as generator + Grype scanner. ([Ox Security][1])
* **Trivy VEX feature request:** exists but not mainstream yet. ([GitHub][2])
* **Snyk platform capability:** scans containers, IaC, dev‑first prioritization. ([Snyk][3])
* **Prisma Cloud container security:** lifecycle scanning + policy. ([Palo Alto Networks][6])
* **Anchore Enterprise SBOM mgmt & policy:** central imports + CI/CD ecosystem. ([Anchore Docs][9])

Below is a **deep, implementation-grade elaboration** that turns the comparison matrix into **actionable architecture and product differentiation** for Stella Ops. I will deliberately avoid marketing language and focus on **mechanics, evidence, and execution gaps**.
---
## 1. Why existing tools plateau (root cause analysis)
Across Trivy, Syft/Grype, Snyk, Prisma, Aqua, Anchore, there is a **structural ceiling** they all hit — regardless of OSS vs enterprise.
### Shared structural limitations
1. **SBOM is treated as a static artifact**
* Generated → stored → scanned.
* No concept of *evolving truth*, lineage, or replayability.
2. **Vulnerability scoring is probabilistic, not provable**
* CVSS + vendor heuristics.
* Cannot answer: *“Show me why this CVE is exploitable here.”*
3. **Exploitability ≠ reachability**
* “Runtime context” ≠ call-path proof.
4. **Diffing is file-level, not semantic**
* Image hash change ≠ security delta understanding.
5. **Offline support is operational, not epistemic**
* You can run it offline, but you cannot **prove** what knowledge state was used.
These are not accidental omissions. They arise from **tooling lineage**:
* Trivy/Syft grew from *package scanners*
* Snyk grew from *developer remediation UX*
* Prisma/Aqua grew from *policy & compliance platforms*
None were designed around **forensic reproducibility or trust algebra**.
---
## 2. SBOM fidelity: what “high fidelity” actually means
Most tools claim CycloneDX/SPDX support. That is **necessary but insufficient**.
### Current reality
| Dimension | Industry tools |
| ----------------------- | ---------------------- |
| Component identity | Package name + version |
| Binary provenance | Weak or absent |
| Build determinism | None |
| Dependency graph | Flat or shallow |
| Layer attribution | Partial |
| Rebuild reproducibility | Not supported |
### What Stella Ops must do differently
**SBOM must become a *stateful ledger*, not a document.**
Concrete requirements:
* **Component identity = (source + digest + build recipe hash)**
* **Binary → source mapping**
* ELF Build-ID / Mach-O UUID / PE timestamp+hash
* **Layer-aware dependency graphs**
* Not “package depends on X”
* But “binary symbol A resolves to shared object B via loader rule C”
* **Replay manifest**
* Exact feeds
* Exact policies
* Exact scoring rules
* Exact timestamps
* Hash of everything
This is the foundation for *deterministic replayable scans* — something none of the competitors even attempt.
---
## 3. VEX handling: ingestion vs decisioning
Most vendors misunderstand VEX.
### What competitors do
* Accept VEX as:
* Metadata
* Annotation
* Suppression rule
* No **formal reasoning** over VEX statements.
### What Stella Ops must do
VEX is not a comment — it is a **logical claim**.
Each VEX statement:
```
IF
product == X
AND component == Y
AND version in range Z
THEN
status ∈ {not_affected, affected, fixed, under_investigation}
BECAUSE
justification J
WITH
evidence E
```
Stella Ops advantage:
* VEX statements become **inputs to a lattice merge**
* Conflicting VEX from:
* Vendor
* Distro
* Internal analysis
* Runtime evidence
* Are resolved **deterministically** via policy, not precedence hacks.
This unlocks:
* Vendor-supplied proofs
* Customer-supplied overrides
* Jurisdiction-specific trust rules
---
## 4. Explainability: reports vs proofs
### Industry “explainability”
* “This vulnerability is high because…”
* Screenshots, UI hints, remediation text.
### Required explainability
Security explainability must answer **four non-negotiable questions**:
1. **What exact evidence triggered this finding?**
2. **What code or binary path makes it reachable?**
3. **What assumptions are being made?**
4. **What would falsify this conclusion?**
No existing scanner answers #4.
### Stella Ops model
Each finding emits:
* Evidence bundle:
* SBOM nodes
* Call-graph edges
* Loader resolution
* Runtime symbol presence
* Assumption set:
* Compiler flags
* Runtime configuration
* Feature gates
* Confidence score **derived from evidence density**, not CVSS
This is explainability suitable for:
* Auditors
* Regulators
* Courts
* Defense procurement
---
## 5. Smart-Diff: the missing primitive
All tools compare:
* Image A vs Image B
* Result: *“+3 CVEs, –1 CVE”*
This is **noise-centric diffing**.
### What Smart-Diff must mean
Diff not *artifacts*, but **security meaning**.
Examples:
* Same CVE remains, but:
* Call path removed → risk collapses
* New binary added, but:
* Dead code → no reachable risk
* Dependency upgraded, but:
* ABI unchanged → no exposure delta
Implementation direction:
* Diff **reachability graphs**
* Diff **policy outcomes**
* Diff **trust weights**
* Diff **unknowns**
Output:
> “This release reduces exploitability surface by 41%, despite +2 CVEs.”
No competitor does this.
---
## 6. Call-stack reachability: why runtime context isn’t enough
### Current vendor claim
“Runtime exploitability analysis.”
Reality:
* Usually:
* Process exists
* Library loaded
* Port open
This is **coarse correlation**, not proof.
### Stella Ops reachability model
Reachability requires **three layers**:
1. **Static call graph**
* From entrypoints to vulnerable symbols
2. **Binary resolution**
* Dynamic loader rules
* Symbol versioning
3. **Runtime gating**
* Feature flags
* Configuration
* Environment
Only when **all three align** does exploitability exist.
This makes false positives *structurally impossible*, not heuristically reduced.
---
## 7. Deterministic scoring: replacing trust with math
Every competitor uses:
* CVSS
* EPSS
* Proprietary weighting
Problem:
* Scores are **non-reproducible**
* Cannot be attested
* Cannot be audited
### Stella Ops scoring
Score = deterministic function of:
* Evidence count
* Evidence strength
* Assumption penalties
* Trust source weights
* Policy constraints
Same inputs → same outputs → forever.
This enables:
* Signed risk decisions
* Cross-org verification
* Legal defensibility
---
## 8. Unknowns as a first-class state
Industry tools suppress uncertainty.
Stella Ops must **surface it**.
States:
* Known-safe
* Known-vulnerable
* **Unknown-reachable**
* **Unknown-unreachable**
Unknowns are **risk**, but different from vulnerabilities.
This is critical for:
* Air-gapped environments
* Novel exploits
* Zero-day windows
No competitor models this explicitly.
---
## 9. Offline / air-gapped: epistemic completeness
Competitors:
* “Yes, we can run offline.”
But cannot answer:
> “Exactly what knowledge did you have when you made this decision?”
Stella Ops must:
* Snapshot feeds
* Snapshot policies
* Snapshot scoring rules
* Snapshot trust anchors
Then bind them cryptographically to scan results.
This creates **forensic replayability**, not just offline execution.
---
## 10. Strategic conclusion (no hype)
### Where Stella Ops can **objectively dominate**
1. Deterministic replayable scans
2. Formal VEX reasoning
3. Reachability-backed exploitability
4. Semantic smart-diff
5. Evidence-first explainability
6. Unknowns modeling

## 📌 Key Notes, Gaps & Opportunities (Markdown)
### **SBOM Fidelity**
* **Open tools (Trivy, Syft)** already support CycloneDX/SPDX output, but mostly as flat SBOM artifacts without long‑term repositories or versioned diffing. ([Ox Security][1])
* **Opportunity:** Provide *repository + lineage + merge semantics* with proofs — not just generation.
### **VEX Handling**
* Trivy has an open feature request for dynamic VEX ingestion. ([GitHub][2])
* Most competitors either lack VEX support or have no *decisioning logic* based on exploitability.
* **Opportunity:** First‑class VEX ingestion with evaluation rules + automated scoring.
### **Explainability**
* Commercial tools (Prisma/Snyk) offer UI report context and dev‑oriented remediation guidance. ([Snyk][3])
* OSS tools provide flat scan outputs with minimal causal trace.
* **Opportunity:** Link vulnerability flags back to *proven code paths*, enriched with SBOM + call reachability.
### **Smart‑Diff & Unknowns State**
* No major tool advertising *smart diffing* between SBOMs for incremental risk deltas across releases.
* **Opportunity:** Automate risk deltas between SBOMs with uncertainty margins.
### **Call‑Stack Reachability**
* None of these tools publicly document call‑stack based exploit reachability analysis out‑of‑the‑box.
* **Opportunity:** Integrate dynamic/static reachability evidence that elevates scanning from surface report → *impact map*.
### **Deterministic Scoring**
* Snyk & Prisma offer proprietary scoring that blends severity + context. ([TrustRadius][4])
* But these aren’t reproducible with *signed verdicts*.
* **Opportunity:** Provide *deterministic, attestable scoring proofs*.
### **Ecosystem Integrations**
* Trivy/Grype excel at lightweight CI/CD and Kubernetes. ([Echo][5])
* Enterprise products integrate deeply into cloud/registry. ([Palo Alto Networks][6])
* **Opportunity:** Expand *sigstore/notation* based pipelines and automated attestation flows.
### **Policy Engine**
* Prisma & Aqua have mature enterprise policies. ([Aqua][7])
* OSS tools have limited simple allow/deny.
* **Opportunity:** Provide *lattice/constraint policies* with proof outputs.
### **Offline/Air‑Gapped**
* Anchore supports air‑gapped deployment in enterprise contexts. ([Anchore][8])
* Support across all open tools is ad‑hoc at best.
* **Opportunity:** Built‑in deterministic offline modes with offline SBOM stores and VEX ingestion.
### **Provenance/Attestations**
* Syft supports SBOM output in various formats; also *in‑toto* for attestations. ([Ox Security][1])
* Most competitors don’t prominently advertise *attestation pipelines*.
* **Opportunity:** End‑to‑end DSSE/in‑toto provenance with immutable proofs.
---
### 📌 Public Evidence Links
* **Trivy / Syft / Grype SBOM support & formats:** CycloneDX/SPDX; Syft as generator + Grype scanner. ([Ox Security][1])
* **Trivy VEX feature request:** exists but not mainstream yet. ([GitHub][2])
* **Snyk platform capability:** scans containers, IaC, dev‑first prioritization. ([Snyk][3])
* **Prisma Cloud container security:** lifecycle scanning + policy. ([Palo Alto Networks][6])
* **Anchore Enterprise SBOM mgmt & policy:** central imports + CI/CD ecosystem. ([Anchore Docs][9])

Below is a **deep, implementation-grade elaboration** that turns the comparison matrix into **actionable architecture and product differentiation** for Stella Ops. I will deliberately avoid marketing language and focus on **mechanics, evidence, and execution gaps**.
---
## 1. Why existing tools plateau (root cause analysis)
Across Trivy, Syft/Grype, Snyk, Prisma, Aqua, Anchore, there is a **structural ceiling** they all hit — regardless of OSS vs enterprise.
### Shared structural limitations
1. **SBOM is treated as a static artifact**
* Generated → stored → scanned.
* No concept of *evolving truth*, lineage, or replayability.
2. **Vulnerability scoring is probabilistic, not provable**
* CVSS + vendor heuristics.
* Cannot answer: *“Show me why this CVE is exploitable here.”*
3. **Exploitability ≠ reachability**
* “Runtime context” ≠ call-path proof.
4. **Diffing is file-level, not semantic**
* Image hash change ≠ security delta understanding.
5. **Offline support is operational, not epistemic**
* You can run it offline, but you cannot **prove** what knowledge state was used.
These are not accidental omissions. They arise from **tooling lineage**:
* Trivy/Syft grew from *package scanners*
* Snyk grew from *developer remediation UX*
* Prisma/Aqua grew from *policy & compliance platforms*
None were designed around **forensic reproducibility or trust algebra**.
---
## 2. SBOM fidelity: what “high fidelity” actually means
Most tools claim CycloneDX/SPDX support. That is **necessary but insufficient**.
### Current reality
| Dimension | Industry tools |
| ----------------------- | ---------------------- |
| Component identity | Package name + version |
| Binary provenance | Weak or absent |
| Build determinism | None |
| Dependency graph | Flat or shallow |
| Layer attribution | Partial |
| Rebuild reproducibility | Not supported |
### What Stella Ops must do differently
**SBOM must become a *stateful ledger*, not a document.**
Concrete requirements:
* **Component identity = (source + digest + build recipe hash)**
* **Binary → source mapping**
* ELF Build-ID / Mach-O UUID / PE timestamp+hash
* **Layer-aware dependency graphs**
* Not “package depends on X”
* But “binary symbol A resolves to shared object B via loader rule C”
* **Replay manifest**
* Exact feeds
* Exact policies
* Exact scoring rules
* Exact timestamps
* Hash of everything
This is the foundation for *deterministic replayable scans* — something none of the competitors even attempt.
---
## 3. VEX handling: ingestion vs decisioning
Most vendors misunderstand VEX.
### What competitors do
* Accept VEX as:
* Metadata
* Annotation
* Suppression rule
* No **formal reasoning** over VEX statements.
### What Stella Ops must do
VEX is not a comment — it is a **logical claim**.
Each VEX statement:
```
IF
product == X
AND component == Y
AND version in range Z
THEN
status ∈ {not_affected, affected, fixed, under_investigation}
BECAUSE
justification J
WITH
evidence E
```
Stella Ops advantage:
* VEX statements become **inputs to a lattice merge**
* Conflicting VEX from:
* Vendor
* Distro
* Internal analysis
* Runtime evidence
* Are resolved **deterministically** via policy, not precedence hacks.
This unlocks:
* Vendor-supplied proofs
* Customer-supplied overrides
* Jurisdiction-specific trust rules
---
## 4. Explainability: reports vs proofs
### Industry “explainability”
* “This vulnerability is high because…”
* Screenshots, UI hints, remediation text.
### Required explainability
Security explainability must answer **four non-negotiable questions**:
1. **What exact evidence triggered this finding?**
2. **What code or binary path makes it reachable?**
3. **What assumptions are being made?**
4. **What would falsify this conclusion?**
No existing scanner answers #4.
### Stella Ops model
Each finding emits:
* Evidence bundle:
* SBOM nodes
* Call-graph edges
* Loader resolution
* Runtime symbol presence
* Assumption set:
* Compiler flags
* Runtime configuration
* Feature gates
* Confidence score **derived from evidence density**, not CVSS
This is explainability suitable for:
* Auditors
* Regulators
* Courts
* Defense procurement
---
## 5. Smart-Diff: the missing primitive
All tools compare:
* Image A vs Image B
* Result: *“+3 CVEs, –1 CVE”*
This is **noise-centric diffing**.
### What Smart-Diff must mean
Diff not *artifacts*, but **security meaning**.
Examples:
* Same CVE remains, but:
* Call path removed → risk collapses
* New binary added, but:
* Dead code → no reachable risk
* Dependency upgraded, but:
* ABI unchanged → no exposure delta
Implementation direction:
* Diff **reachability graphs**
* Diff **policy outcomes**
* Diff **trust weights**
* Diff **unknowns**
Output:
> “This release reduces exploitability surface by 41%, despite +2 CVEs.”
No competitor does this.
---
## 6. Call-stack reachability: why runtime context isn’t enough
### Current vendor claim
“Runtime exploitability analysis.”
Reality:
* Usually:
* Process exists
* Library loaded
* Port open
This is **coarse correlation**, not proof.
### Stella Ops reachability model
Reachability requires **three layers**:
1. **Static call graph**
* From entrypoints to vulnerable symbols
2. **Binary resolution**
* Dynamic loader rules
* Symbol versioning
3. **Runtime gating**
* Feature flags
* Configuration
* Environment
Only when **all three align** does exploitability exist.
This makes false positives *structurally impossible*, not heuristically reduced.
---
## 7. Deterministic scoring: replacing trust with math
Every competitor uses:
* CVSS
* EPSS
* Proprietary weighting
Problem:
* Scores are **non-reproducible**
* Cannot be attested
* Cannot be audited
### Stella Ops scoring
Score = deterministic function of:
* Evidence count
* Evidence strength
* Assumption penalties
* Trust source weights
* Policy constraints
Same inputs → same outputs → forever.
This enables:
* Signed risk decisions
* Cross-org verification
* Legal defensibility
---
## 8. Unknowns as a first-class state
Industry tools suppress uncertainty.
Stella Ops must **surface it**.
States:
* Known-safe
* Known-vulnerable
* **Unknown-reachable**
* **Unknown-unreachable**
Unknowns are **risk**, but different from vulnerabilities.
This is critical for:
* Air-gapped environments
* Novel exploits
* Zero-day windows
No competitor models this explicitly.
---
## 9. Offline / air-gapped: epistemic completeness
Competitors:
* “Yes, we can run offline.”
But cannot answer:
> “Exactly what knowledge did you have when you made this decision?”
Stella Ops must:
* Snapshot feeds
* Snapshot policies
* Snapshot scoring rules
* Snapshot trust anchors
Then bind them cryptographically to scan results.
This creates **forensic replayability**, not just offline execution.
---
## 10. Strategic conclusion (no hype)
### Where Stella Ops can **objectively dominate**
1. Deterministic replayable scans
2. Formal VEX reasoning
3. Reachability-backed exploitability
4. Semantic smart-diff
5. Evidence-first explainability
6. Unknowns modeling
7. Jurisdiction-ready offline trust
### Where competitors remain stronger (for now)
* Mass-market UX polish
* SaaS onboarding friction
* Marketplace integrations
These are solvable later. The **hard parts** above are not.
---
If you want, next I can:
* Convert this into **developer implementation milestones**
* Map features → **moat strength vs competitors**
* Design the **Trust Algebra / Lattice Engine spec**
* Produce a **regulator-grade threat & evidence model**
Tell me which vector you want next.

### 5.10 Vulnerability Surfaces (Sprint 3700)
Vulnerability surfaces identify **which specific methods changed** in a security fix, enabling precise reachability analysis:
- **Surface computation**: Download vulnerable and fixed package versions, fingerprint all methods, diff to find changed methods (sinks).
- **Trigger extraction**: Build internal call graphs, reverse BFS from sinks to public APIs (triggers).
- **Per-ecosystem support**:
- NuGet: Cecil IL fingerprinting
- npm: Babel AST fingerprinting
- Maven: ASM bytecode fingerprinting
- PyPI: Python AST fingerprinting
- **Integration**: `ISurfaceQueryService` queries triggers during scan; use triggers as sinks instead of all package methods.
- **Storage**: `scanner.vuln_surfaces`, `scanner.vuln_surface_sinks`, `scanner.vuln_surface_triggers` tables.
- **Docs**: `docs/contracts/vuln-surface-v1.md` for schema details.
### 5.11 Confidence Tiers
Reachability findings are classified into confidence tiers:
| Tier | Condition | Display | Implications |
|------|-----------|---------|--------------|
| **Confirmed** | Surface exists AND trigger method is reachable | Red badge | Highest confidence—vulnerable code definitely called |
| **Likely** | No surface but package API is called | Orange badge | Medium confidence—package used but specific vuln path unknown |
| **Present** | No call graph, dependency in SBOM | Gray badge | Lowest confidence—cannot determine reachability |
| **Unreachable** | Surface exists AND no trigger reachable | Green badge | High confidence vulnerability is not exploitable |
- Tier assignment logic in `SurfaceAwareReachabilityAnalyzer`
- API responses include `confidenceTier` and `confidenceDisplay`
- UI badges reflect tier colors
- VEX statements reference tier in justification
### 5.12 Reachability Drift (Sprint 3600)
Track function-level reachability changes between scans:
- **New reachable**: Sinks that became reachable (alert)
- **Mitigated**: Sinks that became unreachable (positive)
- **Causal attribution**: Why change occurred (guard removed, new route, code change)
- **Components**: `DriftDetectionEngine`, `PathCompressor`, `DriftCauseExplainer`
- **API**: `POST /api/drift/analyze`, `GET /api/drift/{id}`
- **UI**: `PathViewerComponent`, `RiskDriftCardComponent`
- **Attestation**: DSSE-signed drift predicates for evidence chain

## Reachability Drift (Sprint 3600)
Reachability Drift Detection tracks function-level reachability changes between scans:
### Libraries
- `StellaOps.Scanner.ReachabilityDrift` - Drift detection engine, API models, attestation
- `StellaOps.Scanner.CallGraph` - Language-specific call graph extractors
- `StellaOps.Scanner.VulnSurfaces` - Vulnerability surface computation (trigger methods)
### Key Types
- `ReachabilityDriftResult` - Drift analysis output (newly reachable, mitigated paths)
- `DriftedSink` - Sink that changed reachability state with cause attribution
- `DriftCause` - Causal explanation (guard removed, new route, code change)
- `CompressedPath` - Compact path representation (entrypoint → key nodes → sink)
- `ReachabilityConfidenceTier` - Confirmed/Likely/Present/Unreachable tiers
### Predicate Schema
- URI: `stellaops.dev/predicates/reachability-drift@v1`
- DSSE-signed attestations for drift evidence chain
### Call Graph Support
- **.NET**: Roslyn semantic analysis (`DotNetCallGraphExtractor`)
- **Node.js**: Babel AST analysis (`NodeCallGraphExtractor`)
- **Future**: Java (ASM), Go (SSA), Python (AST)
### Entrypoint Detection
- ASP.NET Core: `[HttpGet]`, `[Route]`, minimal APIs
- Express/Fastify: route handlers
- Background: `IHostedService`, `BackgroundService`
- CLI: `Main`, command handlers
### Drift API Endpoints
- `POST /api/drift/analyze` - Compute drift between two scans
- `GET /api/drift/{driftId}` - Retrieve drift result
- `GET /api/drift/{driftId}/paths` - Get detailed paths
### Testing
- Unit tests: `src/Scanner/__Tests/StellaOps.Scanner.ReachabilityDrift.Tests/`
- Benchmark cases: `bench/reachability-benchmark/`
- Golden fixtures: deterministic path compression, DSSE output
## Vulnerability Surfaces (Sprint 3700)
Compute vulnerability surfaces by diffing vulnerable vs fixed package versions:
### Libraries
- `StellaOps.Scanner.VulnSurfaces` - Surface builder, method fingerprinting, trigger extraction
### Key Types
- `VulnSurface` - Computed surface with sink methods and triggers
- `VulnSurfaceSink` - Method that changed in security fix
- `VulnSurfaceTrigger` - Public API that can reach sink
- `MethodFingerprint` - Stable method identity across versions
### Per-Ecosystem Support
- **NuGet**: Cecil IL fingerprinting
- **npm**: Babel AST fingerprinting
- **Maven**: ASM bytecode fingerprinting
- **PyPI**: Python AST fingerprinting
### Integration with Reachability
- `ISurfaceQueryService` - Query triggers for CVE during scan
- Confidence tiers: Confirmed (trigger reachable) > Likely (API reachable) > Present (dep only)
- Path witnesses include surface evidence for audit trail
