Foreword. Data Artifact: the machine-readable twin of VRS-FLD-201 (VRS 2026 (draft)) — the sector criteria with their point ranges, rungs and tier ceilings, the contributing intrinsic criteria, the letter bands and the application classes — generated FROM the protocol’s Clause 5–7 by
tools/vrs-twin-generate.py. Consistency is by construction and re-verified on every build (conformance check 15). The JSON in Clause 4 is the normative payload; scorer tooling consumes it directly. A change to VRS-FLD-201 and to this twin is one change instrument.
1 Scope
This Data Artifact carries the rubric data of the Field & Outdoor (FLD) sector in machine-readable form: the 9 sector criteria of VRS-FLD-201 Clause 6 with points, rungs and Unverified / Verified / Certified ceilings; the contributing intrinsic criteria of Clause 5; the letter bands and application classes of Clause 7. It states no independent requirements. Where this artifact and VRS-FLD-201 could be read to differ, VRS-FLD-201 governs and this twin is regenerated to match.

3 Terms and definitions
The terms of VRS-GEN-001 and VRS-FLD-201 apply. data twin — a machine-readable artifact regenerated one-to-one from a source protocol’s normative clauses. rung — a named state of a criterion awarding a stated integer number of points (VRS-GEN-002 §3.9). ceiling — the maximum points a criterion awards at a stated tier (VRS-GEN-002 §3.10).
4 Payload
Sector criteria total 100 points; ceilings Unverified 70, Verified 85, Certified 100.

| Field | Meaning |
|---|---|
sector_criteria[].clause |
VRS-FLD-201 subclause (6.k) — the “Required by” reference used in derived packs and protocols |
sector_criteria[].points_max |
Upper end of the criterion’s integer range |
sector_criteria[].rungs[] |
Every verifiable state and its points, highest first; the 0 state is implicit where not listed |
sector_criteria[].ceiling |
Maximum points at each tier; always equal to a rung value (VRS-GEN-002 §7.5.1) |
sector_criteria[].company_wide |
Field-record criteria only: the reduced ceiling when company-wide data substitutes for model data |
sector_criteria[].applicability / not_applicable_by_class |
Application classes the criterion applies to; excluded criteria leave the pool for that class |
contributing_ir_criteria[] |
Intrinsic criteria counted in the sector pool, with the standard and clause that score them |
pool.sector_only |
Sums over the sector criteria and the best attainable letter at each tier (A / AA / AAA by construction) |
bands_percent |
Letter thresholds as a percentage of the applicable pool (VRS-GEN-006 §4) |
6 Verification
Regenerate with python3 tools/vrs-twin-generate.py --sector fld --check; a non-zero exit means the
committed twin no longer matches VRS-FLD-201 and shall be regenerated before publication.
