I’m sharing this because I think the comparison will help sharpen some of the UI/UX & data-model decisions for StellaOps — especially around how “evidence + suppression + audit/export” flows are implemented in existing tools and which patterns we might want to emulate or avoid.

Here’s a compact snapshot (with recent documentation/screens and dates) of how a few major players — Snyk, GitHub (via repo scanning), Aqua Security / container scanning, Anchore/Grype, and Prisma Cloud — handle evidence, ignores (suppression / VEX), and audit/export primitives.

---

## ✅ What works: Evidence & audit flows that provide clarity

**Snyk — good “evidence + data flow + context” for code vulnerabilities**

* In Snyk Code, each issue links to a full “Data flow” trace from source to sink. ([Snyk User Docs][1])
* The UI hyperlinks to the Git repo, providing code-level context and version control traceability. ([Snyk User Docs][1])
* “Fix analysis” surfaces recommended fixes, diff examples, and community-driven suggestions. ([Snyk User Docs][1])

This deep evidence linkage is a valuable pattern for StellaOps triage and remediation.

**Anchore/Grype — VEX-aware suppression + SBOM export readiness**

* Anchore Enterprise documents vulnerability annotations + VEX support (SBOM scanning, annotations, fix statuses). ([Anchore Documentation][2])
* Grype respects VEX statuses (`not_affected`, `fixed`) and can expose suppressed matches via `--show-suppressed`. ([GitHub][3])
* Justifications can be scoped (e.g., `vulnerable_code_not_present` filters) and the API surfaces (Oct 2025) enable automation of SBOM + VEX + diffed results. ([Anchore Documentation][2])

This forms a solid SBOM → vulnerability → VEX → audit/export pipeline.

---

## ⚠️ Where things are brittle

**Snyk — suppression semantics vary across scan types**

* Ignore rules are project/integration-specific; UI ignores may not carry over to CLI import flows. ([Snyk][4])
* Snyk Code uses separate suppression UX (IDE/CLI) from OSS scans, leading to fragmentation. ([Snyk User Docs][5])

**Anchore/Grype — operational caveats**

* Feb 2025 issue: VEX suppression failed for directory scans because the source type wasn’t supported. ([GitHub][6])
* Some suppressions require explicit config (`GRYPE_VEX_ADD`). ([GitHub][3])
* Ensuring SBOM + VEX + diffed outputs for audits often needs extra orchestration.

**Prisma Cloud — audit/export primitives are coarse**

* “Suppress Code Issues” feature exists, but no public doc shows an end-to-end SBOM + VEX + audit export flow. ([Prisma Cloud Documentation][7])
* Repo scanning + suppression features exist, but forensic traceability appears limited to “report + suppress”. ([Prisma Cloud Documentation][8])

---

## 🔑 What StellaOps should copy / avoid

**Copy**

* Snyk Code evidence + fix linking provides actionable traceability.
* Anchore/Grype SBOM → VEX suppression → facade for automation is the workflow to engineer.
* Surface suppression metadata (reason, status, justification) for auditing suppressed items.

**Avoid**

* Fragmented ignore rules per scan surface (OSS vs Code vs Container). Instead, keep suppression consistent.
* Hidden suppression; tie it to the main UI instead of a “show suppressed” toggle.
* Incomplete VEX support for certain source types; test across containers, directories, binaries, SBOMs.

If helpful, I can build a spreadsheet (Snyk, GitHub, Aqua, Anchore/Grype, Prisma Cloud) comparing evidence, suppression, APIs, exports, and gaps with doc links.

## 1. Evidence & context: what a *single finding* looks like

| Dimension                           | Snyk                                                                                                                                                        | GitHub Advanced Security                                                                                                                                         | Aqua / Trivy                                                                                                                                             | Anchore / Grype (Anchore Enterprise)                                                                                                                                                  | Prisma Cloud                                                                                                                                                                                  |
| ----------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Code-level evidence**             | Snyk Code shows a *Data flow* view (taint graph) from source → sink with step-by-step code lines in the UI and IDE. ([docs.snyk.io][1])                     | Code scanning alerts show file/line and, for data-flow rules, a “how data moves through the code” view with **Show paths** for the full flow. ([GitHub Docs][2]) | Trivy is not a SAST engine; evidence is per-file / resource for vulnerabilities & misconfigurations (IaC, K8s, etc.), not data-flow graphs. ([Trivy][3]) | No SAST; evidence is package / image / SBOM level (CVE, package, version, location). Grype is focused on images/filesystems, not code flows. ([Chainguard Academy][4])                | AppSec module shows issues mapped to file & line and offers inline remediation/fix flows; surfaced in console and IDE plugins (JetBrains/VS Code). ([Palo Alto Networks][5])                  |
| **Dependency / container evidence** | For OSS & containers, Snyk shows dependency paths and has a **project issue paths** API that returns the introduction chain for a vuln. ([docs.snyk.io][6]) | Dependabot alerts show vulnerable package, version, advisories, and affected functions to help decide if code actually uses them. ([GitHub Docs][7])             | Trivy shows image → layer → package → vuln with installed/fixed versions; same for repos & filesystems in JSON/SARIF. ([GitHub][8])                      | Grype output lists artifact, package, version, location, severity; when paired with Syft SBOM, you get full component graph for images and other artifacts. ([Chainguard Academy][4]) | Prisma’s Vulnerability Explorer & scan reports show image/host, package, severity and compliance IDs for image and host scans. ([docs.prismacloud.io][9])                                     |
| **SBOM / supply-chain context**     | `snyk sbom` generates CycloneDX and SPDX SBOMs for local projects; Snyk also supports SBOM export in enterprise tiers. ([docs.snyk.io][10])                 | GitHub builds a dependency graph from manifests and ingests SARIF from external scanners; it is SBOM-adjacent but not an SBOM UI. ([GitHub Docs][11])            | Trivy can output SBOMs (CycloneDX, SPDX, SPDX-JSON) and Kubernetes “KBOM” views, and is often used as the SBOM generator. ([Chainguard Academy][12])     | Anchore Enterprise is explicitly “SBOM-powered”; SBOM management views let you navigate applications and export SBOM-centric vulnerability views. ([docs.anchore.com][13])            | Prisma Cloud is inventory-/RQL-centric; SBOMs are not a first-class UI artifact and there is no public doc for full SBOM navigation comparable to Anchore or Trivy. ([Palo Alto Networks][5]) |
| **Where the evidence appears**      | Web UI, CLI, IDEs (VS Code, JetBrains) and PR checks. Ignores for Snyk Code are now “consistent” across UI/CLI/IDE (2025-11 EA). ([docs.snyk.io][14])       | Web UI (Security tab), PR Conversation tab for code scanning reviews, REST & GraphQL APIs, and SARIF imports from many scanners. ([GitHub Docs][15])             | Trivy: CLI / JSON / SARIF / CI integrations (GitHub Actions, etc.). Aqua Platform adds a CNAPP UI with risk-based vulnerability views. ([GitHub][8])     | Grype: CLI & JSON/SARIF outputs; Anchore Enterprise: browser UI (dashboards, SBOM views, reporting) plus REST/GraphQL APIs. ([Chainguard Academy][4])                                 | Prisma Cloud: web console (AppSec dashboards, Vulnerability Explorer), REST APIs, IDE plugins for JetBrains & VS Code. ([docs.prismacloud.io][16])                                            |

| **Suppression primitives**               | `.snyk` policy file for OSS & container & IaC; `snyk ignore` CLI; “Ignore” in web UI; Snyk Code uses UI/CLI/IDE ignores but *not* `.snyk`. ([docs.snyk.io][17])                                                               | Code scanning and Dependabot alerts can be **dismissed** with reasons; Dependabot has auto-triage rules (auto-dismiss/snooze). ([GitHub Docs][18])                                             | Trivy: `.trivyignore` / `.trivyignore.yaml` lists vuln IDs; `--ignore-policy` for Rego-based filtering; severity filters. ([aquasecurity.github.io][19])                                                                                                     | Grype: VEX-aware filtering via `--vex` and ignore rules; Anchore Enterprise: UI-driven vulnerability annotations that act as a structured “suppress or re-classify” layer. ([GitHub][20])                                                      | AppSec: “Suppress Code Issues” (per-issue or globally) and more general suppression rules (disable policy / by source / by resource / by tag). ([docs.prismacloud.io][21])                               |
| **Metadata captured with suppression**   | `snyk ignore` supports `--reason` and `--expiry`; UI shows who ignored and allows editing/unignore; APIs expose `ignoreReasons` on issues. ([docs.snyk.io][17])                                                               | Dismissal reason: `false positive`, `won't fix`, `used in tests`; optional comment. Dismissal requests for code scanning add requester/reviewer, timestamps, status. ([GitHub Docs][22])       | Ignores live in repo-local files (`.trivyignore*`) or Rego policies; VEX documents contribute status metadata (per CVE, per product). No central UI metadata by default. ([aquasecurity.github.io][19])                                                      | Annotations carry VEX-aligned status plus explanatory text; RBAC role `vuln-annotator-editor` controls who can create/modify/delete them. ([docs.anchore.com][23])                                                                             | Suppressions include justification text; there is a dedicated API to retrieve suppression justifications by policy ID and query (auditable). ([pan.dev][24])                                             |
| **Scope & consistency**                  | Ignores are *local* to project/integration/org; ignoring in a Git repo project does not automatically ignore the same issue imported via CLI. Snyk Code ignore semantics differ from OSS/Container (no `.snyk`). ([Snyk][25]) | Dismissals attach to a specific alert (repo, branch baseline); PRs inherit baseline. Dependabot has repo-level config (`dependabot.yml`) and org-level alert configuration. ([GitHub Docs][7]) | Suppression is run-local: `.trivyignore` travels with source, policies live in config repos; VEX docs are attached per artifact or discovered via VEX Hub / registries. Reproducible but not centralized unless you build it. ([aquasecurity.github.io][19]) | Grype suppression is per scan & VEX document; Anchore Enterprise stores annotations centrally per artifact and exposes them consistently in UI/API and exported VEX. ([GitHub][20])                                                            | Suppression rules can be global, per source, per resource, or tag-scoped; they affect console views and API results consistently when filters are applied. ([pan.dev][24])                               |
| **VEX support (ingest + semantics)**     | Snyk generates SBOMs but has no documented first-class VEX ingestion or export; VEX is referenced mostly at the SBOM/standards level, not as a product feature. ([Snyk][26])                                                  | No native VEX semantics in alerts; GitHub consumes SARIF only. VEX can exist in repos or external systems but is not interpreted by GHAS. ([GitHub Docs][11])                                  | Trivy has **explicit VEX support**: supports OpenVEX, CycloneDX VEX, and CSAF VEX, using local files, VEX repositories, SBOM externalReferences, and OCI VEX attestations to filter results. ([Trivy][27])                                                   | Grype has VEX-first behavior: `--vex` to ingest OpenVEX; by default `not_affected`/`fixed` go to an ignore set; `--show-suppressed` exposes them. Anchore Enterprise 5.22+ adds OpenVEX export and CycloneDX VEX export (5.23). ([GitHub][20]) | No public documentation of native VEX ingestion or export; prioritization is via policies/RQL rather than VEX semantics.                                                                                 |
| **Default handling of suppressed items** | Ignored issues are hidden by default in UI/CLI/IDE views to reduce noise; some tools like `snyk-to-html` will still show ignored Snyk Code issues. ([docs.snyk.io][28])                                                       | Dismissed / auto-dismissed alerts are *not* shown by default (`is:open` filter); you must explicitly filter for closed / auto-dismissed alerts. ([GitHub Docs][29])                            | When VEX is supplied, non-affected/fixed statuses are filtered out; suppressed entries are generally not shown unless you adjust filters/output. Some edge-cases exist around `.trivyignore.yaml` behavior. ([Trivy][27])                                    | Grype hides suppressed matches unless `--show-suppressed` is set; community discussions explicitly argue for “suppressed hidden by default” across all formats. ([artifacthub.io][30])                                                         | Suppressed / excluded issues are hidden from normal risk views and searches and only visible via explicit filters or suppression APIs. ([pan.dev][24])                                                   |
| **Known pain points**                    | Fragmented semantics: Snyk Code vs OSS/Container vs IaC handle ignores differently; ignores are not global across ingest types. ([docs.snyk.io][31])                                                                          | Dismissal is per-tool: Dependabot rules don’t govern CodeQL and vice-versa; no VEX; you must build cross-tool policy on top.                                                                   | Some rough edges reported around `.trivyignore.yaml` and SARIF vs exit-code behavior; VEX support is powerful but still labeled experimental in docs. ([GitHub][32])                                                                                         | VEX support for certain source types (e.g., some directory + SBOM combos) has had bugs; suppressed entries disappear by default unless you remember `--show-suppressed`. ([GitHub][33])                                                        | No VEX, and suppression semantics may diverge across CSPM/AppSec/Compute; complexity of RQL and multiple modules can make suppression strategy opaque without good governance.

## 3. Audit & export primitives

| Dimension                                  | Snyk                                                                                                                                                                                                        | GitHub Advanced Security                                                                                                                                                                                                            | Aqua / Trivy                                                                                                                                                                                                                            | Anchore / Grype (Anchore Enterprise)                                                                                                                                                                                   | Prisma Cloud                                                                                                                                                                                                   |

| **Built-in UI exports**                    | Reporting UI lets you export reports as PDF and table data as CSV; you can also download CSV from several report views. ([docs.snyk.io][34])                                                                | UI is mostly “view only”; some security overview exports are available, but reports are usually built via API or marketplace actions (e.g., PDF report GitHub Action). ([GitHub Docs][35])                                          | Aqua Platform provides CSV exports and API integrations for vulnerability reports; on-prem deployments can export “user policy data, vulnerability data and system settings data.” ([Aqua][36])                                         | SBOM/Vulnerability views have an **Export CSV** button; the Reports service aggregates via GraphQL into CSV/JSON from pre-built templates and dashboards. ([docs.anchore.com][37])                                     | Vulnerability Explorer and scan reports allow CSV export; code-build issues can be exported with filters as CSV from the AppSec UI. ([docs.prismacloud.io][16])                                                |
| **Machine-readable exports / APIs**        | REST Issues API; Export API (GA) to create CSV exports via async jobs; SBOM CLI (`snyk sbom`) for CycloneDX/SPDX; audit log export for user actions. ([docs.snyk.io][38])                                   | SARIF input/output; REST & GraphQL APIs for code scanning & Dependabot; many third-party actions to transform alerts into PDFs/CSVs or send to other systems. ([GitHub Docs][11])                                                   | Trivy outputs JSON, SARIF, CycloneDX, SPDX, SPDX-JSON, GitHub formats; these can be uploaded into GHAS or other platforms. Aqua exposes vulnerability data via API. ([Trivy][39])                                                       | Grype outputs JSON, table, CycloneDX, SARIF, plus Go-template based CSV; Anchore Enterprise exposes APIs for vulnerabilities, policies, and reports. ([Chainguard Academy][4])                                         | CSPM/AppSec APIs: `vulnerabilities/search` (JSON) and `.../search/download` (GZIP CSV) for RQL queries; broader Prisma Cloud API for automation/integration. ([pan.dev][40])                                   |
| **VEX / “authoritative statement” export** | No native VEX export; at best you can export SBOMs and issues and post-process into VEX with external tooling. ([Snyk][26])                                                                                 | None. Vendors can publish VEX separately, but GHAS doesn’t emit VEX.                                                                                                                                                                | Trivy consumes VEX but does not itself author VEX; Aqua operates VEX Hub as a central repository of vendor VEX documents rather than as a generator. ([Trivy][27])                                                                      | Anchore Enterprise 5.22/5.23 is currently the most “productized” VEX exporter: OpenVEX and CycloneDX VEX including annotations, PURLs, metadata about the scanned image. ([docs.anchore.com][41])                      | No VEX export; risk posture is expressed via internal policies, not standardized exploitability statements.                                                                                                    |
| **Suppression / ignore audit**             | Ignored issues can be exported by filtering for “Ignored” in Reporting and downloading CSV; APIs expose ignore reasons; audit log export records user actions such as ignoring issues. ([docs.snyk.io][42]) | Code scanning dismissal requests are full audit records (who requested, who approved, reason, timestamps). Dependabot dismissal comments & auto-dismissed alerts are queryable via GraphQL/REST and UI filters. ([GitHub Docs][43]) | Auditability is repo-driven: `.trivyignore`/VEX/rego live in version control; Aqua’s own reporting/APIs can include current vulnerability state but do not (publicly) expose a dedicated VEX change log. ([aquasecurity.github.io][19]) | Annotations are first-class objects, controlled via RBAC and exportable as OpenVEX/CycloneDX VEX; this effectively *is* an audit log of “why we suppressed or downgraded this CVE” over time. ([docs.anchore.com][23]) | Suppression justification APIs provide a structured record of why and where policies are suppressed; combined with CSV/API exports of vulns, this gives a workable audit trail for regulators. ([pan.dev][24]) |

## 4. What this suggests for StellaOps UX & data-model

### Patterns worth copying

1. **Data-flow & path-level “evidence” as the default detail view**

   * Snyk Code’s taint-flow UI and GitHub’s “Show paths” for CodeQL alerts make a single issue *explain itself* without leaving the tool. ([docs.snyk.io][1])
   * For StellaOps:

     * For code: provide a path graph (source → sanitizers → sinks) with line-level jumps.
     * For SBOM/containers: mirror Snyk’s Project Issue Paths & Grype/Syft by showing a dependency path or image-layer path for each CVE.

2. **VEX-first suppression semantics**

   * Trivy and Grype treat VEX as the *canonical* suppression mechanism; statuses like `not_affected` / `fixed` hide findings by default, with CLI flags to show suppressed. ([Trivy][27])
   * Anchore Enterprise adds a full annotation workflow and emits OpenVEX/CycloneDX VEX as the authoritative vendor statement. ([docs.anchore.com][23])
   * For StellaOps: make VEX status the **single source of truth** for suppression across all modules, and always be able to reconstruct a proof tree: SBOM → vuln → VEX statement → policy decision.

3. **Rich suppression metadata with explicit justification & expiry**

   * Snyk captures reason + expiry; GitHub uses structured reasons + free-form comment; Prisma provides a dedicated suppression-justification API. ([docs.snyk.io][17])
   * For StellaOps: require a reason taxonomy + free-text + optional “proof link” (e.g., internal ticket, upstream vendor VEX) for any “Not Affected” or “Won’t Fix,” and store that as part of the public proof spine.

4. **Strong export & API stories for regulators**

   * Snyk’s Export API, Anchore’s Reports service, and Prisma’s RQL+CSV APIs give customers reliable machine-readable exports for audits and custom BI. ([updates.snyk.io][44])
   * Anchore’s CycloneDX VEX export is the best current model for “signable, portable, regulator-friendly” proofs. ([Security Boulevard][45])
   * For StellaOps:

     * Treat CSV/JSON/SBOM/VEX exports as *first-class* features, not add-ons.
     * Tie them to deterministic scan manifests and graph revision IDs (your “trust algebra” backbone) so an auditor can replay any historical report.

5. **Repo-local suppression files as “policy as code”**

   * `.snyk`, `.trivyignore`, Rego policies, and VEX docs living alongside source are proven patterns for reproducible suppression. ([docs.snyk.io][46])
   * For StellaOps: mirror this with a small set of declarative files (`stellaops.vexmap.yaml`, `trust-lattice.yaml`) that your engine and UI both honor.

### Patterns to deliberately avoid

1. **Fragmented ignore semantics by scan type**

   * Snyk’s different behavior across Code vs OSS vs Container vs IaC (e.g., `.snyk` not honored for Snyk Code) is a recurring source of confusion. ([docs.snyk.io][31])
   * For StellaOps: a single suppression model (VEX+policy) must apply consistently whether the evidence came from SAST, SBOM, container scan, or runtime telemetry.

2. **Making suppressed issues effectively invisible**

   * Grype and GitHub both hide suppressed/dismissed issues by default and require extra flags/filters to see them. ([artifacthub.io][30])
   * For StellaOps:

     * Default UI for any artifact should show a small, always-visible “suppressed” counter with a click-through view.
     * Every export format should have an option to include suppressed entries with their VEX status and reasoning.

3. **Lack of a standard “authoritative statement” artifact**

   * Snyk, GitHub, Prisma Cloud all rely on internal notions of suppression and policy without emitting a standardized VEX or equivalent artifact. ([Snyk][26])
   * For StellaOps: your “Proof-of-Integrity Graph” and VEX exports should be the primary way vendors and customers communicate risk, not just internal UI states.

4. **Over-reliance on informal text for serious decisions**

   * Many tools lean heavily on free-form comments (GitHub dismissal comments, Snyk ignore reasons) without tying them to structured policies or verifiable upstream evidence. ([GitHub Docs][22])
   * For StellaOps: keep free text, but anchor it in structured fields (VEX status, justification category, linked upstream VEX/SBOM, ticket ID) and make these queryable across the entire system.

If you want, next step can be a **StellaOps UX spec** that maps each of these rows to concrete screens and micro-interactions (e.g., “Finding details drawer,” “Suppression dialog,” “Export / attest dialog”) so your .NET/Angular team has something they can implement directly.

Matrix built. I’ll keep it compact enough to scan quickly, but detailed enough that you can lift it straight into a Google Sheet / Confluence page.

## 1. Evidence & context: what a *single finding* looks like

| Dimension                           | Snyk                                                                                                                                                        | GitHub Advanced Security                                                                                                                                         | Aqua / Trivy                                                                                                                                             | Anchore / Grype (Anchore Enterprise)                                                                                                                                                  | Prisma Cloud                                                                                                                                                                                  |
| ----------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Code-level evidence**             | Snyk Code shows a *Data flow* view (taint graph) from source → sink with step-by-step code lines in the UI and IDE. ([docs.snyk.io][1])                     | Code scanning alerts show file/line and, for data-flow rules, a “how data moves through the code” view with **Show paths** for the full flow. ([GitHub Docs][2]) | Trivy is not a SAST engine; evidence is per-file / resource for vulnerabilities & misconfigurations (IaC, K8s, etc.), not data-flow graphs. ([Trivy][3]) | No SAST; evidence is package / image / SBOM level (CVE, package, version, location). Grype is focused on images/filesystems, not code flows. ([Chainguard Academy][4])                | AppSec module shows issues mapped to file & line and offers inline remediation/fix flows; surfaced in console and IDE plugins (JetBrains/VS Code). ([Palo Alto Networks][5])                  |
| **Dependency / container evidence** | For OSS & containers, Snyk shows dependency paths and has a **project issue paths** API that returns the introduction chain for a vuln. ([docs.snyk.io][6]) | Dependabot alerts show vulnerable package, version, advisories, and affected functions to help decide if code actually uses them. ([GitHub Docs][7])             | Trivy shows image → layer → package → vuln with installed/fixed versions; same for repos & filesystems in JSON/SARIF. ([GitHub][8])                      | Grype output lists artifact, package, version, location, severity; when paired with Syft SBOM, you get full component graph for images and other artifacts. ([Chainguard Academy][4]) | Prisma’s Vulnerability Explorer & scan reports show image/host, package, severity and compliance IDs for image and host scans. ([docs.prismacloud.io][9])                                     |
| **SBOM / supply-chain context**     | `snyk sbom` generates CycloneDX and SPDX SBOMs for local projects; Snyk also supports SBOM export in enterprise tiers. ([docs.snyk.io][10])                 | GitHub builds a dependency graph from manifests and ingests SARIF from external scanners; it is SBOM-adjacent but not an SBOM UI. ([GitHub Docs][11])            | Trivy can output SBOMs (CycloneDX, SPDX, SPDX-JSON) and Kubernetes “KBOM” views, and is often used as the SBOM generator. ([Chainguard Academy][12])     | Anchore Enterprise is explicitly “SBOM-powered”; SBOM management views let you navigate applications and export SBOM-centric vulnerability views. ([docs.anchore.com][13])            | Prisma Cloud is inventory-/RQL-centric; SBOMs are not a first-class UI artifact and there is no public doc for full SBOM navigation comparable to Anchore or Trivy. ([Palo Alto Networks][5]) |
| **Where the evidence appears**      | Web UI, CLI, IDEs (VS Code, JetBrains) and PR checks. Ignores for Snyk Code are now “consistent” across UI/CLI/IDE (2025-11 EA). ([docs.snyk.io][14])       | Web UI (Security tab), PR Conversation tab for code scanning reviews, REST & GraphQL APIs, and SARIF imports from many scanners. ([GitHub Docs][15])             | Trivy: CLI / JSON / SARIF / CI integrations (GitHub Actions, etc.). Aqua Platform adds a CNAPP UI with risk-based vulnerability views. ([GitHub][8])     | Grype: CLI & JSON/SARIF outputs; Anchore Enterprise: browser UI (dashboards, SBOM views, reporting) plus REST/GraphQL APIs. ([Chainguard Academy][4])                                 | Prisma Cloud: web console (AppSec dashboards, Vulnerability Explorer), REST APIs, IDE plugins for JetBrains & VS Code.

| **Suppression primitives**               | `.snyk` policy file for OSS & container & IaC; `snyk ignore` CLI; “Ignore” in web UI; Snyk Code uses UI/CLI/IDE ignores but *not* `.snyk`. ([docs.snyk.io][17])                                                               | Code scanning and Dependabot alerts can be **dismissed** with reasons; Dependabot has auto-triage rules (auto-dismiss/snooze). ([GitHub Docs][18])                                             | Trivy: `.trivyignore` / `.trivyignore.yaml` lists vuln IDs; `--ignore-policy` for Rego-based filtering; severity filters. ([aquasecurity.github.io][19])                                                                                                     | Grype: VEX-aware filtering via `--vex` and ignore rules; Anchore Enterprise: UI-driven vulnerability annotations that act as a structured “suppress or re-classify” layer. ([GitHub][20])                                                      | AppSec: “Suppress Code Issues” (per-issue or globally) and more general suppression rules (disable policy / by source / by resource / by tag). ([docs.prismacloud.io][21])                               |
| **Metadata captured with suppression**   | `snyk ignore` supports `--reason` and `--expiry`; UI shows who ignored and allows editing/unignore; APIs expose `ignoreReasons` on issues. ([docs.snyk.io][17])                                                               | Dismissal reason: `false positive`, `won't fix`, `used in tests`; optional comment. Dismissal requests for code scanning add requester/reviewer, timestamps, status. ([GitHub Docs][22])       | Ignores live in repo-local files (`.trivyignore*`) or Rego policies; VEX documents contribute status metadata (per CVE, per product). No central UI metadata by default. ([aquasecurity.github.io][19])                                                      | Annotations carry VEX-aligned status plus explanatory text; RBAC role `vuln-annotator-editor` controls who can create/modify/delete them. ([docs.anchore.com][23])                                                                             | Suppressions include justification text; there is a dedicated API to retrieve suppression justifications by policy ID and query (auditable). ([pan.dev][24])                                             |
| **Scope & consistency**                  | Ignores are *local* to project/integration/org; ignoring in a Git repo project does not automatically ignore the same issue imported via CLI. Snyk Code ignore semantics differ from OSS/Container (no `.snyk`). ([Snyk][25]) | Dismissals attach to a specific alert (repo, branch baseline); PRs inherit baseline. Dependabot has repo-level config (`dependabot.yml`) and org-level alert configuration. ([GitHub Docs][7]) | Suppression is run-local: `.trivyignore` travels with source, policies live in config repos; VEX docs are attached per artifact or discovered via VEX Hub / registries. Reproducible but not centralized unless you build it. ([aquasecurity.github.io][19]) | Grype suppression is per scan & VEX document; Anchore Enterprise stores annotations centrally per artifact and exposes them consistently in UI/API and exported VEX. ([GitHub][20])                                                            | Suppression rules can be global, per source, per resource, or tag-scoped; they affect console views and API results consistently when filters are applied. ([pan.dev][24])                               |
| **VEX support (ingest + semantics)**     | Snyk generates SBOMs but has no documented first-class VEX ingestion or export; VEX is referenced mostly at the SBOM/standards level, not as a product feature. ([Snyk][26])                                                  | No native VEX semantics in alerts; GitHub consumes SARIF only. VEX can exist in repos or external systems but is not interpreted by GHAS. ([GitHub Docs][11])                                  | Trivy has **explicit VEX support**: supports OpenVEX, CycloneDX VEX, and CSAF VEX, using local files, VEX repositories, SBOM externalReferences, and OCI VEX attestations to filter results. ([Trivy][27])                                                   | Grype has VEX-first behavior: `--vex` to ingest OpenVEX; by default `not_affected`/`fixed` go to an ignore set; `--show-suppressed` exposes them. Anchore Enterprise 5.22+ adds OpenVEX export and CycloneDX VEX export (5.23). ([GitHub][20]) | No public documentation of native VEX ingestion or export; prioritization is via policies/RQL rather than VEX semantics.                                                                                 |
| **Default handling of suppressed items** | Ignored issues are hidden by default in UI/CLI/IDE views to reduce noise; some tools like `snyk-to-html` will still show ignored Snyk Code issues. ([docs.snyk.io][28])                                                       | Dismissed / auto-dismissed alerts are *not* shown by default (`is:open` filter); you must explicitly filter for closed / auto-dismissed alerts. ([GitHub Docs][29])                            | When VEX is supplied, non-affected/fixed statuses are filtered out; suppressed entries are generally not shown unless you adjust filters/output. Some edge-cases exist around `.trivyignore.yaml` behavior. ([Trivy][27])                                    | Grype hides suppressed matches unless `--show-suppressed` is set; community discussions explicitly argue for “suppressed hidden by default” across all formats. ([artifacthub.io][30])                                                         | Suppressed / excluded issues are hidden from normal risk views and searches and only visible via explicit filters or suppression APIs. ([pan.dev][24])                                                   |
| **Known pain points**                    | Fragmented semantics: Snyk Code vs OSS/Container vs IaC handle ignores differently; ignores are not global across ingest types. ([docs.snyk.io][31])                                                                          | Dismissal is per-tool: Dependabot rules don’t govern CodeQL and vice-versa; no VEX; you must build cross-tool policy on top.                                                                   | Some rough edges reported around `.trivyignore.yaml` and SARIF vs exit-code behavior; VEX support is powerful but still labeled experimental in docs. ([GitHub][32])                                                                                         | VEX support for certain source types (e.g., some directory + SBOM combos) has had bugs; suppressed entries disappear by default unless you remember `--show-suppressed`. ([GitHub][33])                                                        | No VEX, and suppression semantics may diverge across CSPM/AppSec/Compute; complexity of RQL and multiple modules can make suppression strategy opaque without good governance.

| **Built-in UI exports**                    | Reporting UI lets you export reports as PDF and table data as CSV; you can also download CSV from several report views. ([docs.snyk.io][34])                                                                | UI is mostly “view only”; some security overview exports are available, but reports are usually built via API or marketplace actions (e.g., PDF report GitHub Action). ([GitHub Docs][35])                                          | Aqua Platform provides CSV exports and API integrations for vulnerability reports; on-prem deployments can export “user policy data, vulnerability data and system settings data.” ([Aqua][36])                                         | SBOM/Vulnerability views have an **Export CSV** button; the Reports service aggregates via GraphQL into CSV/JSON from pre-built templates and dashboards. ([docs.anchore.com][37])                                     | Vulnerability Explorer and scan reports allow CSV export; code-build issues can be exported with filters as CSV from the AppSec UI.

| **Machine-readable exports / APIs**        | REST Issues API; Export API (GA) to create CSV exports via async jobs; SBOM CLI (`snyk sbom`) for CycloneDX/SPDX; audit log export for user actions. ([docs.snyk.io][38])                                   | SARIF input/output; REST & GraphQL APIs for code scanning & Dependabot; many third-party actions to transform alerts into PDFs/CSVs or send to other systems. ([GitHub Docs][11])                                                   | Trivy outputs JSON, SARIF, CycloneDX, SPDX, SPDX-JSON, GitHub formats; these can be uploaded into GHAS or other platforms. Aqua exposes vulnerability data via API. ([Trivy][39])                                                       | Grype outputs JSON, table, CycloneDX, SARIF, plus Go-template based CSV; Anchore Enterprise exposes APIs for vulnerabilities, policies, and reports. ([Chainguard Academy][4])                                         | CSPM/AppSec APIs: `vulnerabilities/search` (JSON) and `.../search/download` (GZIP CSV) for RQL queries; broader Prisma Cloud API for automation/integration. ([pan.dev][40])                                   |
| **VEX / “authoritative statement” export** | No native VEX export; at best you can export SBOMs and issues and post-process into VEX with external tooling. ([Snyk][26])                                                                                 | None.

([docs.anchore.com][41])                      | No VEX export; risk posture is expressed via internal policies, not standardized exploitability statements.                                                                                                    |
| **Suppression / ignore audit**             | Ignored issues can be exported by filtering for “Ignored” in Reporting and downloading CSV; APIs expose ignore reasons; audit log export records user actions such as ignoring issues. ([docs.snyk.io][42]) | Code scanning dismissal requests are full audit records (who requested, who approved, reason, timestamps). Dependabot dismissal comments & auto-dismissed alerts are queryable via GraphQL/REST and UI filters. ([GitHub Docs][43]) | Auditability is repo-driven: `.trivyignore`/VEX/rego live in version control; Aqua’s own reporting/APIs can include current vulnerability state but do not (publicly) expose a dedicated VEX change log. ([aquasecurity.github.io][19]) | Annotations are first-class objects, controlled via RBAC and exportable as OpenVEX/CycloneDX VEX; this effectively *is* an audit log of “why we suppressed or downgraded this CVE” over time. ([docs.anchore.com][23]) | Suppression justification APIs provide a structured record of why and where policies are suppressed; combined with CSV/API exports of vulns, this gives a workable audit trail for regulators. ([pan.dev][24]) |

## 4. What this suggests for StellaOps UX & data-model

### Patterns worth copying

1. **Data-flow & path-level “evidence” as the default detail view**

   * Snyk Code’s taint-flow UI and GitHub’s “Show paths” for CodeQL alerts make a single issue *explain itself* without leaving the tool. ([docs.snyk.io][1])
   * For StellaOps:

     * For code: provide a path graph (source → sanitizers → sinks) with line-level jumps.
     * For SBOM/containers: mirror Snyk’s Project Issue Paths & Grype/Syft by showing a dependency path or image-layer path for each CVE.

2. **VEX-first suppression semantics**

   * Trivy and Grype treat VEX as the *canonical* suppression mechanism; statuses like `not_affected` / `fixed` hide findings by default, with CLI flags to show suppressed. ([Trivy][27])
   * Anchore Enterprise adds a full annotation workflow and emits OpenVEX/CycloneDX VEX as the authoritative vendor statement. ([docs.anchore.com][23])
   * For StellaOps: make VEX status the **single source of truth** for suppression across all modules, and always be able to reconstruct a proof tree: SBOM → vuln → VEX statement → policy decision.

3. **Rich suppression metadata with explicit justification & expiry**

   * Snyk captures reason + expiry; GitHub uses structured reasons + free-form comment; Prisma provides a dedicated suppression-justification API. ([docs.snyk.io][17])
   * For StellaOps: require a reason taxonomy + free-text + optional “proof link” (e.g., internal ticket, upstream vendor VEX) for any “Not Affected” or “Won’t Fix,” and store that as part of the public proof spine.

4. **Strong export & API stories for regulators**

   * Snyk’s Export API, Anchore’s Reports service, and Prisma’s RQL+CSV APIs give customers reliable machine-readable exports for audits and custom BI. ([updates.snyk.io][44])
   * Anchore’s CycloneDX VEX export is the best current model for “signable, portable, regulator-friendly” proofs. ([Security Boulevard][45])
   * For StellaOps:

     * Treat CSV/JSON/SBOM/VEX exports as *first-class* features, not add-ons.
     * Tie them to deterministic scan manifests and graph revision IDs (your “trust algebra” backbone) so an auditor can replay any historical report.

5. **Repo-local suppression files as “policy as code”**

   * `.snyk`, `.trivyignore`, Rego policies, and VEX docs living alongside source are proven patterns for reproducible suppression. ([docs.snyk.io][46])
   * For StellaOps: mirror this with a small set of declarative files (`stellaops.vexmap.yaml`, `trust-lattice.yaml`) that your engine and UI both honor.

### Patterns to deliberately avoid

1. **Fragmented ignore semantics by scan type**

   * Snyk’s different behavior across Code vs OSS vs Container vs IaC (e.g., `.snyk` not honored for Snyk Code) is a recurring source of confusion. ([docs.snyk.io][31])
   * For StellaOps: a single suppression model (VEX+policy) must apply consistently whether the evidence came from SAST, SBOM, container scan, or runtime telemetry.

2. **Making suppressed issues effectively invisible**

   * Grype and GitHub both hide suppressed/dismissed issues by default and require extra flags/filters to see them. ([artifacthub.io][30])
   * For StellaOps:

     * Default UI for any artifact should show a small, always-visible “suppressed” counter with a click-through view.
     * Every export format should have an option to include suppressed entries with their VEX status and reasoning.

3. **Lack of a standard “authoritative statement” artifact**

   * Snyk, GitHub, Prisma Cloud all rely on internal notions of suppression and policy without emitting a standardized VEX or equivalent artifact. ([Snyk][26])
   * For StellaOps: your “Proof-of-Integrity Graph” and VEX exports should be the primary way vendors and customers communicate risk, not just internal UI states.

4. **Over-reliance on informal text for serious decisions**

   * Many tools lean heavily on free-form comments (GitHub dismissal comments, Snyk ignore reasons) without tying them to structured policies or verifiable upstream evidence. ([GitHub Docs][22])
   * For StellaOps: keep free text, but anchor it in structured fields (VEX status, justification category, linked upstream VEX/SBOM, ticket ID) and make these queryable across the entire system.

If you want, next step can be a **StellaOps UX spec** that maps each of these rows to concrete screens and micro-interactions (e.g., “Finding details drawer,” “Suppression dialog,” “Export / attest dialog”) so your .NET/Angular team has something they can implement directly.

I’ll treat this as a concrete UX blueprint your .NET/Angular team can build against, centered on three pillars:

1. Evidence views (how a single finding “explains itself”)
2. Suppression/VEX (how risk decisions are captured)
3. Audit/export (how you prove those decisions later)

---

## 1. Design principles specific to StellaOps

1. **Graph-first:** Every view is anchored to a graph snapshot ID from your trust algebra / proof engine. Users always know “which build / which graph revision” they’re looking at.
2. **Single suppression model:** One suppression semantics layer (VEX + policy) across code, SBOM, containers, and runtime.
3. **Evidence before opinion:** Detail views always show raw evidence (paths, SBOM lines, runtime traces) before risk ratings, policies, or comments.
4. **Audit-ready by default:** Any action that changes risk posture automatically leaves a machine-readable trail that can be exported.

---

## 2. Core information architecture

Primary entities in the UX (mirroring your backend):

* **Organization / Workspace**
* **Application / Service**
* **Artifact**

  * Build (commit, tag, CI run)
  * Container image
  * Binary / package
  * SBOM document
* **Scan Result**

  * Scanner type (SAST, SCA, container, SBOM-only, IaC, runtime)
  * Graph snapshot ID
* **Finding**

  * Vulnerability (CVE, GHSA, etc.)
  * Misconfiguration / policy violation
  * Supply-chain anomaly
* **Evidence**

  * Code path(s)
  * Dependency path(s)
  * SBOM node(s)
  * Runtime event(s)
* **VEX Statement**

  * Status (`affected`, `not_affected`, `fixed`, `under_investigation`, etc.)
  * Justification (standardized + free text)
* **Suppression Decision**

  * “Suppressed by VEX”, “De-prioritized by policy”, “Won’t fix”, etc.
* **Export Job / Proof Bundle**
* **Audit Event**

  * Who, what, when, against which graph snapshot

The UI should surface these without drowning the user in jargon: names can be friendlier but map cleanly to this model.

---

## 3. UX spec by primary flows

### 3.1 Landing: Inventory & posture overview

**Screen: “Inventory & Risk Overview”**

Purpose: Secure default entry point for security engineers and auditors.

Layout:

* **Header bar**

  * Org selector
  * Global search (by application, artifact, CVE, VEX ID, SBOM component)
  * “Exports & Proofs” shortcut
  * User menu

* **Left nav (primary)**

  * Inventory
  * Findings
  * VEX & Policies
  * Exports & Proofs
  * Settings

* **Main content: 3 panels**

  1. **Applications list**

     * Columns: Name, Owner, #Artifacts, Open findings, Suppressed findings, Last build, Risk score.
     * Row click → Application view.
  2. **Top risks**

     * Cards: “Critical vulns”, “Unsigned artifacts”, “Unknown SBOM coverage”, each showing counts and a “View findings” link (pre-filtered).
  3. **Compliance viewpoint**

     * Tabs: “Operational”, “Regulatory”, “Attestations”.
     * Simple status indicators per framework (e.g., SLSA level, NIST SSDF coverage) if you support that.

Micro-interactions:

* Clicking any numeric count (e.g., “12 suppressed”) opens a pre-filtered Findings list.
* Hover tooltip on risk counts shows breakdown by source (SAST vs SBOM vs runtime).

---

### 3.2 Application & artifact detail: evidence-centric view

**Screen: “Application detail”**

Purpose: Navigate from high level risk to specific artifacts and findings.

Layout:

* Tabs: Overview | Artifacts | Findings | SBOM graph | History

**Overview tab:**

* Top: Application summary (owners, repos, deployment targets).
* Middle: Tiles for “Latest build”, “Prod artifacts”, “SBOM coverage”.
* Bottom: “Recent decisions” timeline (suppression, VEX updates, exports).

**Artifacts tab:**

* Table with:

  * Artifact type (image, binary, SBOM-only)
  * Identifier (tag/digest, CI job ID)
  * Environment (dev, staging, prod)
  * Graph snapshot ID
  * Findings (open / suppressed chips)
  * Last scanned

Selecting a row opens **Artifact detail**.

---

### 3.3 Artifact detail & Finding details drawer

**Screen: “Artifact detail”**

Layout:

* Header:

  * Artifact identity (name, version/tag, digest)
  * Environment badges
  * Graph snapshot ID with “Copy” control
  * Primary actions: “Download SBOM”, “Export proof bundle”

* Sub-tabs:

  * Findings
  * Evidence graph
  * SBOM tree
  * History

**Findings sub-tab**

* Filters on left:

  * Severity, status (Open / Suppressed / Only suppressed), source (SAST/SBOM/container/runtime), VEX status, CWE/CVE.
* Table in center:

  * Columns: Severity, Type, ID (CVE-XXXX-XXXX), Component/Code location, Status (Open/Suppressed), VEX status, Last updated.
* Row click opens a **Finding details drawer** sliding from the right.

**Finding details drawer (core evidence UX)**

This is the primary place where “evidence explains itself.”

Structure:

1. **Header area**

   * Title: “CVE-2023-XXXX in `openssl`”
   * Badges: severity, status (Open / Suppressed by VEX), VEX status (`not_affected`, `fixed`, etc.)
   * Scope indicator: where this finding appears (e.g., “1 artifact (this), 3 environments, 2 images”).

2. **Tabs within drawer**

   * **Evidence** (default)

     * Section: “Where this comes from”

       * Scanner source, scan timestamp, graph snapshot ID.
     * Section: “Code path” (for SAST)

       * A vertical list of steps: `source` → `propagation` → `sink`.
       * Clicking a step shows code snippet with line highlighting.
       * “Open in Git” and “Open in IDE (deeplink)” actions.
     * Section: “Dependency path” (for SCA / SBOM)

       * Path view: `app -> module -> transitive dependency -> vulnerable package`.
       * Option to switch between “tree view” and “collapsed chain”.
     * Section: “Runtime signals” (if available)

       * Call-site frequency, exploit attempts, telemetry tags.

   * **Impact & reach**

     * A small graph panel: how many artifacts, environments, and applications share this finding.
     * Link: “View all affected artifacts” → filtered Findings view.

   * **VEX & decisions**

     * Shows current VEX statements attached:

       * Table: Status, Justification (standardized), Source (vendor vs internal), Effective scope (artifact / app / org), Last changed by.
     * Shows local suppression decisions beyond VEX (e.g., “De-prioritized due to compensating controls”).
     * Primary action: “Update status / Add VEX decision”.

   * **History**

     * Timeline of events for this finding:

       * Detected
       * VEX attached/updated
       * Suppression added/edited
       * Exported in bundles (with links)
     * Each item shows user, timestamp, and delta.

Micro-interactions:

* The drawer should support deep-linking: URL reflects `artifactId + findingId + snapshotId`.
* Keyboard: `Esc` closes drawer, `←` / `→` cycles findings in the table.

---

## 4. Suppression & VEX UX

Goal: one consistent model across all scan types, anchored in VEX semantics.

### 4.1 “Update status / Add VEX decision” dialog

Entry points:

* From Finding details drawer > “VEX & decisions” tab > primary button.
* Bulk selection from Findings table > “Update status”.

Dialog steps (single modal with progressive disclosure):

1. **Select decision type**

   Radio options:

   * “System is affected”

     * Sub-options: `under_investigation`, `affected_no_fix_available`, `affected_fix_available`.
   * “System is *not* affected”

     * Sub-options (justification): `vulnerable_code_not_present`, `vulnerable_code_not_in_execute_path`, `vulnerable_configuration_not_present`, `inline_mitigation_applied`, `other`.
   * “Fixed”

     * Sub-options: `fixed_in_this_version`, `fixed_in_downstream`, `fixed_by_vendor`.
   * “Won’t fix / accepted risk”

     * Sub-options: `business_acceptance`, `low_likelihood`, `temporary_exception`.

2. **Scope definition**

   Checkboxes + selectors:

   * Scope:

     * [x] This artifact only
     * [ ] All artifacts of this application
     * [ ] All artifacts in this org with the same component & version
   * For each, display a short estimate: “This will apply to 3 artifacts (click to preview).”

3. **Metadata**

   * Required:

     * Justification category (if not chosen above).
     * Free-text “Reason / supporting evidence” (min length e.g., 20 characters).
   * Optional:

     * Expiry date (for temporary exceptions).
     * Link to ticket / document (URL).
     * Attach external VEX file ID or reference (if you’ve ingested vendor VEX).

4. **Output preview**

   A read-only JSON-like preview of the VEX statement(s) to be generated, with a friendly label: “These statements will be added to the proof graph for snapshot XYZ.”
   This makes the model transparent to power users.

On submit:

* Show a small toast: “Status updated · VEX statement anchored to snapshot [ID] · Undo” (undo limited to a short window).
* The Finding row and drawer update immediately (status badges, history timeline).

### 4.2 Bulk suppression & policy overlay

**Screen: “VEX & Policies”**

Tabs:

1. **VEX statements**

   * Table: VEX ID, CVE/ID, Status, Scope, Created by, Last updated, Source (vendor/internal).
   * Filters: status, scope, target (component, application, artifact).
   * Bulk actions: Export VEX (OpenVEX / CycloneDX VEX), disable / supersede.

2. **Policies**

   * Declarative rules like: “Treat `vulnerable_code_not_present` from vendor X as authoritative” or “Do not auto-suppress based on `inline_mitigation_applied` without internal confirmation.”
   * This expresses how raw VEX translates into “suppressed” vs “needs review” in the UI.

UX pattern:

* Each VEX row includes a small indicator: `S` (suppresses findings under current policy) or `R` (requires review).
* Clicking a row opens a side drawer with:

  * Statements content (normalized).
  * Affected findings count.
  * Policy evaluation result (“This statement currently suppresses 47 findings”).

---

## 5. Findings list: global “inbox” for risk

**Screen: “Findings”**

This is the cross-application queue, similar to Snyk’s project list + GitHub’s security tab, but with VEX semantics.

Layout:

* Filters on the left:

  * Application / artifact
  * Severity
  * Status (Open / Suppressed / Only suppressed / Needs review)
  * VEX status
  * Source (SAST, SBOM, container, runtime)
* Table in center:

  * Columns: Severity, ID, Application, Artifact, Status, VEX status, “Decision owner” (user or team), Age.
* Top bar:

  * “Assign to…” for workflow
  * “Update status / Add VEX decision” for bulk
  * “Export current view” (CSV/JSON)

Micro-interactions:

* “Status” column clearly distinguishes:

  * Open (no VEX)
  * Open (VEX says `affected`)
  * Suppressed (VEX says `not_affected` / `fixed`)
  * Suppressed (policy exception: “Won’t fix”)
* Hover on “Suppressed” shows a tooltip with the justification and who made the decision.

---

## 6. Audit & export / Proof bundles

### 6.1 Exports list

**Screen: “Exports & Proofs”**

Purpose: centralized, auditable place for generating and revisiting proofs.

Layout:

* Top actions:

  * “New export / proof bundle”
  * Filters: type (CSV, JSON, SBOM, VEX, composite bundle), created by, status.

* Table:

  * Name / description
  * Type (e.g., “OpenVEX for app ‘payments’”, “Proof bundle for prod rollout 2025-03-01”)
  * Scope (org / app / artifact / snapshot range)
  * Includes suppressed? (Yes/No)
  * Status (Complete / Failed)
  * Created by, Created at
  * Download button

### 6.2 “New export / proof bundle” flow

1. **What do you need?**

   Choices:

   * SBOM export (CycloneDX/SPDX)
   * VEX export (OpenVEX / CycloneDX VEX)
   * Findings export (CSV / JSON)
   * Proof bundle (zip containing SBOM + VEX + findings + manifest)

2. **Scope**

   * Radio:

     * A single artifact (picker)
     * All artifacts of an application (picker)
     * Entire org, limited by:

       * Time window (from..to)
       * Environments (prod only / all)
   * Optional: choose graph snapshot(s) (latest vs explicit ID).

3. **Options**

   * Include suppressed findings:

     * [x] Yes, include them, with reasons
     * [ ] No, only unresolved
   * Mask sensitive fields? (e.g., repository URLs)
   * Include audit log excerpt:

     * [x] VEX & suppression decisions
     * [ ] All user actions

4. **Review & create**

   * Show a summary:

     * N artifacts, M findings, K VEX statements.
   * Button: “Create export”.

Once complete:

* Row in the table is updated with a download button.
* Clicking a row opens an **Export detail drawer**:

  * Manifest preview (JSON-like).
  * Link to the associated graph snapshot IDs.
  * Embedded notice that “Regulators can verify this bundle by validating manifest signature and graph snapshot hash” (if you sign them).

Micro-interaction:

* For artifacts and applications, the Artifact detail and Application detail pages should have contextual buttons:

  * “Export SBOM”
  * “Export VEX”
  * “Download proof bundle”

These open the same export dialog pre-populated with the relevant scope.

---

## 7. History & audit trail UX

Audit must be first-class, not buried.

**Pattern: Timeline component**

Used in:

* Application > History
* Artifact > History
* Finding > History
* VEX statement > History
* Export > Details

Timeline item shape:

* Icon (type of action: scan, decision, export)
* Title (short, human readable)
* Metadata:

  * User
  * Timestamp
  * Graph snapshot ID
* Detail:

  * Before/after summary (e.g., “VEX status: `affected` → `not_affected`”)

Filters:

* By actor (user / system)
* By action type (scan, VEX change, suppression, export, policy change)
* By time range

Long-term: this timeline can become your “forensic report” generator.

---

## 8. Role-based slices

You can keep a single UX codebase but offer different “home” experiences per role.

1. **Security engineer**

   * Default landing: “Findings” with open & needs-review filters.
   * Emphasis on Evidence & VEX decisions.
   * Quick actions: create VEX, adjust policies.

2. **Developer**

   * Default landing: “My assignments” (subset of Findings where they’re the owner).
   * Simplified VEX dialog:

     * Emphasis on “Fixed in commit X” and “Provide more evidence” rather than full-blown VEX authoring.
   * Tight links to repo/IDE.

3. **Auditor / Compliance**

   * Default landing: “Exports & Proofs”.
   * Views oriented around applications and time windows, not individual findings.
   * Read-only access to VEX & policies; can request evidence rather than editing it.

Role behavior is enforced by RBAC, but the UX is guided by ship-ready presets.

---

## 9. Implementation checklist for your .NET/Angular team

To make this action-ready:

1. **Routes / pages**

   * `/inventory`
   * `/applications/:appId`
   * `/artifacts/:artifactId`
   * `/findings`
   * `/vex`
   * `/exports`
   * `/settings`

2. **Core reusable components**

   * Graph snapshot badge (with copy & deeplink).
   * Findings table (configurable columns, selection).
   * Finding details drawer (tabs: Evidence / Impact / VEX & decisions / History).
   * VEX status badge.
   * Timeline component.
   * Export job dialog & list.

3. **API contracts to align with UX**

   * `GET /artifacts/:id/findings?snapshot=...`
   * `GET /findings/:id?includeEvidence=true`
   * `POST /vex/statements` (supports scoped statements).
   * `GET /vex/statements?filters...`
   * `POST /exports` + `GET /exports/:id`
   * `GET /audit?scopeType=&scopeId=&range=...`

4. **Deep-linking**

   * URLs should embed at least `snapshotId` for deterministic views:

     * `/artifacts/:artifactId/findings/:findingId?snapshot=:snapshotId`

5. **Telemetry for UX refinement**

   * Track frequency of:

     * Evidence tab switches (Code vs Dependency vs Runtime).
     * VEX edits per finding.
     * Export jobs by type.
   * Use this to prioritize which evidence views to optimize first.

---

If you want a next step, I can translate this into:

* A low-fidelity screen map (per route, per component), or
* An example JSON schema for VEX statements + proof bundles that matches the UI’s expectations,

so your backend and frontend teams can converge on a single contract.
