# Sprint 0509 · Ops & Offline · Samples (190.D)

## Topic & Scope
- Produce and curate large-scale fixtures for graph, vulnerability explorer, and linkset/VEX scenarios to support performance and regression suites.
- Focus on sample data parity with current schemas across Graph, Concelier, Excititor, and UI/CLI consumers.
- **Working directory:** `samples`.

## Dependencies & Concurrency
- Upstream schema readiness: Concelier/Excititor linkset formats; Graph overlays; Scanner SBOM bundles.
- Relies on AirGap/Offline kit feeds to mirror sample availability for offline validation.

## Documentation Prerequisites
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/graph/implementation_plan.md (for graph fixture shape)
- docs/modules/concelier/architecture.md (for linkset schema/statuses)
- docs/modules/vuln-explorer/architecture.md

| 1 | SAMPLES-GRAPH-24-003 | BLOCKED | Await Graph overlay format decision + mock SBOM cache availability | Samples Guild · SBOM Service Guild | Generate large-scale SBOM graph fixture (~40k nodes) with policy overlay snapshot for perf/regression suites. |
| 2 | SAMPLES-GRAPH-24-004 | TODO | Blocked on 24-003 fixture availability | Samples Guild · UI Guild | Create vulnerability explorer JSON/CSV fixtures capturing conflicting evidence and policy outputs for UI/CLI automated tests. |
| 3 | SAMPLES-LNM-22-001 | BLOCKED | PREP-SAMPLES-LNM-22-001-WAITING-ON-FINALIZED | Samples Guild · Concelier Guild | Create advisory observation/linkset fixtures (NVD, GHSA, OSV disagreements) for API/CLI/UI tests with documented conflicts. |

## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-11-19 | Normalized PREP-SAMPLES-LNM-22-001 Task ID (removed trailing hyphen) for dependency tracking. | Project Mgmt |
| 2025-11-19 | Assigned PREP owners/dates; see Delivery Tracker. | Planning |
| 2025-11-18 | Drafted fixture plan (`samples/graph/fixtures-plan.md`) outlining contents, assumptions, and blockers for SAMPLES-GRAPH-24-003. | Samples |
| 2025-11-18 | Kicked off SAMPLES-GRAPH-24-003 (overlay format + mock bundle sources); other tasks unchanged. | Samples |
| 2025-11-18 | Normalised sprint to standard template; renamed from SPRINT_509_samples.md. | Ops/Docs |
| 2025-11-19 | Marked SAMPLES-GRAPH-24-003 BLOCKED pending Graph overlay format decision and mock SBOM cache availability. | Implementer |

## Decisions & Risks
- Linkset fixtures blocked by Concelier/Excititor schema finalization; revisit once schemas freeze.
- Large graph fixture: overlay format + mock SBOM bundle sources being aligned with Graph Guild; risk of mismatch until confirmed.
- Ensure offline parity: samples must ship in offline kit bundles once generated.
- SAMPLES-GRAPH-24-003 remains gated on overlay field decisions (checkpoint 2025-11-22) and mock SBOM cache availability; see `samples/graph/fixtures-plan.md`.

## Next Checkpoints
- 2025-11-20 · Confirm linkset schema freeze; unblock SAMPLES-LNM-22-001. Owner: Concelier Guild.
- 2025-11-22 · Decide graph overlay format for 40k-node fixture (SAMPLES-GRAPH-24-003). Owner: Graph Guild.
- 2025-11-27 · Reassess readiness to start SAMPLES-GRAPH-24-004 after 24-003 artifact exists. Owner: Samples Guild.
