Raw Blame History

Pack 19 — Security consolidated around release decisions + audit outputs (preserving all PoC screens; reachability stays 2nd‑class)

Below:

  1. Security menu graph (Mermaid)

  2. For each screen:

    • Formerly (old name/location)
    • Why moved/reshaped
    • Screen navigation graph (Mermaid)
    • ASCII mock

19.1 Security menu graph (Mermaid)

This keeps every PoC screen, but organizes them in a “Stella Ops” order: decision‑centric first, then exploration, then data backends, then attestations/waivers.

flowchart TD
  SEC[Security (ROOT)] --> SEC_OV[Risk Overview]
  SEC --> SEC_FIND[Findings Explorer]
  SEC --> SEC_VULN[Vulnerabilities Explorer]
  SEC --> SEC_SBOM[SBOM Data]
  SEC_SBOM --> SEC_LAKE[SBOM Lake]
  SEC_SBOM --> SEC_GRAPH[SBOM Graph]
  SEC --> SEC_VEX[VEX & Exceptions]
  SEC_VEX --> SEC_VEXH[VEX Hub]
  SEC_VEX --> SEC_EXC[Exceptions]

  %% Cross-links (no duplication)
  SEC_OV -. "data confidence" .-> OPS_DI[Ops: Data Integrity]
  SEC_FIND -. "open env" .-> RC_ENV[Release Control: Env Detail]
  SEC_FIND -. "open bundle version" .-> BVER[Bundles: Bundle Version Detail]
  SEC_FIND -. "export decision pack" .-> EVID[Evidence: Export Center]
  SEC_VULN -. "graph" .-> SEC_GRAPH
  SEC_EXC -. "approval gating" .-> APPR[Approvals]
  SEC_VEXH -. "issuer trust" .-> TRUST[Evidence: Trust & Signing]

Key consolidation rule:

  • Findings = “what is actually present in a specific env/bundle/digest, and is it reachable?”
  • Vulnerabilities = “the CVE/catalog view (global), then drill down to where it hits.”
  • SBOM Lake/Graph = storage/exploration backends (kept, but demoted under “SBOM Data”).
  • VEX/Exceptions = disposition/waiver layer tied to approvals and audit.

19.2 Security screen — Risk Overview

Formerly

  • Security → Overview (security overview.png) (cards and summary, not tightly tied to env/bundle decision outcomes)

Why changed like this

This becomes the security commander’s “brief”: what blocks promotions, which envs have critical reachable, SBOM freshness/coverage, VEX/exceptions posture, and data confidence (feeds/jobs/integrations).

Reachability is not promoted to a top-level area; it appears as:

  • summary metrics
  • filters
  • drilldowns into Findings.

19.3 Security screen — Findings Explorer

Formerly

  • Security → Findings (findings.png) (global list; in PoC the table looked empty / placeholder)

Why changed like this

Findings are what matter for release decisions. This screen becomes the primary explorer with first-class filters:

  • Region / Env / Env type
  • Bundle version (manifest digest)
  • Component digest
  • Severity
  • Reachability class (reachable / not reachable / unknown)
  • Hybrid evidence presence (B/I/R) as filters/columns (2nd-class, but not buried)
  • SBOM freshness status (ok/stale/missing/pending)

It also shows a Data Confidence banner so you never misread stale results as “clean”.

19.4 Security screen — Finding Detail (new, minimal but necessary)

Formerly

  • No explicit “Finding Detail” screen shown; users would pivot:

    • Vulnerabilities list
    • SBOM Graph
    • VEX Hub
    • Exceptions …without a single “case file.”

Why changed like this

This is the decision artifact:

  • “Is it reachable?” and why (and with what hybrid evidence)
  • What envs/bundles are impacted
  • Whether VEX exists / whether an exception exists
  • Links to approvals blocked by this finding

19.5 Security screen — Vulnerabilities Explorer

Formerly

  • Security → Vulnerabilities (vulnerabilities.png) (CVE catalog list)

Why changed like this

This remains the catalog view, but becomes release-relevant by adding:

  • “impacted environments count”
  • “crit reachable envs count”
  • “affected bundle versions count”
  • quick filters: “only affecting prod”, “only reachable”, “only without VEX”, “only with expiring exception”.

Reachability remains 2nd-class: it’s derived from correlated findings, not a separate domain.

This is the “CVE dossier” inside Stella:

  • shows where it hits (envs/bundles/components)
  • reachability distribution
  • VEX statements and exceptions status
  • links to SBOM Graph paths and evidence export

19.9 Security screen — VEX Hub

Formerly

  • Security → VEX Hub (vex hub.png) (statement ingestion/management)

Why changed like this

Keep intact, but align to governance:

  • show “statements affecting blocked approvals”
  • show issuer trust status (links to Evidence → Trust & Signing)
  • provide “apply VEX to finding” workflow as a controlled action (audited)

19.10 Security screen — Exceptions

Formerly

  • Security → Exceptions (exceptions.png) (likely waivers, policy exceptions, risk acceptances)

Why changed like this

Keep it intact, but force “release governance shape”:

  • exceptions are time-bound, scoped (env/bundle/component/CVE), and audited
  • shows “exceptions expiring soon” prominently
  • links to approvals using this exception (so you see operational dependency)

What this consolidation fixes (in practical terms)

  • Decision-first navigation: security starts with “what blocks releases / where CritR exists”, not raw SBOM tooling.
  • Reachability is second-class but visible: it’s a column/filter everywhere it matters (Findings/Vulns/Detail), not a buried third-class afterthought.
  • Audit friendliness: each screen has explicit export hooks into Evidence (decision packets, exception ledger, filtered findings sets).
  • No feature loss: SBOM Lake/Graph, VEX Hub, Exceptions remain exactly as capabilities—just grouped and linked to approvals/releases/environment context.

If you want the next pack, Pack 20 can do the same consolidation for Evidence & Audit (Evidence Bundles, Export Center, Replay/Verify, Trust & Signing) so audit outputs are “release/bundle/env centric” and still preserve all PoC screens.
