This release moves the LM-79 attestation to Full and zonal lumens to Standard, and requires a positive number of lumen-maintenance hours or a populated maintenance table. There is no schema structure or vocabulary change; the ConformanceLevel description is corrected, and the IndoorOutdoor title and description are clarified. The workbook template and converter assembly logic do not change. Newly converted records default to 1.16.0. The builder moves to 0.10.0, and the scope manifest contract moves to 2.0.0.

For consumers

Stored records re-grade on validation, and every stored record must re-stamp its index with ulc build-index. Until re-stamped, ulc validate and ulc build-index --check report index drift on builder_version.

A record at Standard without photometry.zonal_lumens grades Core, including a workbook-converted record without a zonal_lumens sheet: the converter does not compute zones from the photometric file. A record held at Core only by a missing LM-79 attestation grades Standard if it carries zonal lumens and meets the other Standard rows. A record at Standard on a claim type, an identifier, LM-80 test data without a projection (test_hours, temperature, current), or zero hours grades Core. A record at Full on a zero projection grades Standard, or Core where that zero was its only stated hours. A record at Full whose lm_79* attestation carries no source_document_ref, or only the draft sentinel hash, grades Standard.

The two moved gap strings are unchanged and appear under a new next_conformance_level. The scope manifest lists the two items at their new tiers, changing their (tier, path) identities. This is a break of the scope contract, so scope_version moves to 2.0.0; the gating table changes on two rows.

Grading

• LM-79 attestation moves from Standard to Full, keeping source document test_report and standard LM-79. An lm_79* attestation counts only with a source_document_ref object with a non-empty filename and a 64-character lowercase hexadecimal SHA-256 hash other than the all-zero missing-file sentinel. The status word does not decide the row.
• /photometry/zonal_lumens moves from Full to Standard, keeping source document ies and standard LM-79.
• The Standard /lumen_maintenance_luminaire (or /lumen_maintenance_package) row requires positive manufacturer_rated_claim.claimed_hours, positive tm_28.tm_28_projection_hours, a CIE 97 table with a numeric lmf in lmf_by_cleanliness_and_interval or numeric llmf or lsf in llmf_by_hours, or a package entry with positive tm_21_projection_hours. An hours-only table entry does not count; a factor of zero is read data and counts.
• The Full method-backed lumen maintenance (TM-21 hours or TM-28) row requires positive TM-21 or TM-28 projection hours. The helper predicates that switch on enrichment remain unchanged, so enrichment output is unchanged.

Examples

• selux-aya-pole-sr-ho-3000k re-grades from standard to core: its cutsheet states no lumen-maintenance hours, and the record's zero is a placeholder. Every other example keeps its grade.
• erco-quintessence-30416-023, lumenpulse-lumenfacade-loi-12-rgb-30x60-ts0, lumenpulse-lumenfacade-loi-12-rgbw30k-10x60-ts2-5 and vode-nexa-suspended-807-so-3500k-90cri-hl-black-48in gain photometry.zonal_lumens, five bands each, computed from the record's own pinned IES file: for each C-plane the candela curve is integrated by trapezoid over the vertical angle weighted by its sine, split at the band edges, and each plane is weighted by its angular cell; the bands from 0-30 to 0-90 are cumulative from 0 degrees. Each value carries provenance source ies, method computed, and the record's attestation reference. On both Lumenpulse records and Vode the 0-90 and 90-180 bands note that their sum differs from the record's stated total flux, which is unchanged.

Documentation

• The methodology, attestation guide, how-it-works guide, validator and examples READMEs, workbook guide, sheet design and code comments, taxonomy conformance description, and roadmap describe the revised ladder and hours rule.
• The IndoorOutdoor title and description say the field records the intended use the product is sold for, not its environment rating; the enum is unchanged.
