# Samples Prep — PREP-SAMPLES-LNM-22-001

Status: **Ready for implementation** (2025-11-20)
Owners: Samples Guild · Concelier Guild
Scope: Produce finalized advisory linkset samples aligned to frozen Concelier linkset schema (LNM-21-002 freeze on 2025-11-20).

## Inputs
- Link-Not-Merge schema: `docs/modules/concelier/link-not-merge-schema.md` (frozen 2025-11-20) and samples under `docs/samples/lnm/`.
- Evidence bundle v1 and console fixtures (for hashes) already published.

## Deliverables
- Two NDJSON fixtures placed under `samples/linkset/`:
  - `lnm-advisories-sample.ndjson` — 1k advisory observations with conflicts (NVD vs GHSA vs OSV) using frozen schema.
  - `lnm-vex-sample.ndjson` — 500 VEX linkset entries with differing exploitability per product.
- Each file accompanied by `.sha256` hash.
- README (`samples/linkset/README.md`) describing schema version, generation seed, and deterministic ordering rules.

## Determinism
- Generation seed: `2025-01-01T00:00:00Z` (use in faker/RNG).
- Sort records by `observationId` before writing; timestamps set to deterministic `2025-01-02T00:00:00Z` for all entries.

## Acceptance criteria
- Files validate against frozen LNM schema without additional fields.
- Hashes recorded; no external network calls to create fixtures.
- README references the schema doc and seed; links added back into Sprint 0509 Delivery Tracker.
