Exit signs and emergency luminaires become first-class, gradable product classes. Two new optional blocks (exit_sign and emergency), ten new taxonomy vocabularies, and per-class grading profiles let an exit-sign-only or emergency-only manufacturer reach the grade its cutsheets actually support rather than being stranded at incomplete for lacking an LM-79 report it never produces. Every change is additive and non-gating: a v0.9.x record validates and grades identically, and no existing grade or index.conformance_level moves.

For consumers

Unlike 0.9.0, this release changes no finding codes and needs no migration. The new class-gated conformance/gap and conformance/enrichment rows appear only on records whose primary_category is exit_sign or emergency_luminaire, or that author the new emergency block; no existing record can trigger them, because the two blocks did not exist before this version. BuilderVersion is unchanged, and the index schema and its projections are unchanged: a sign record's index simply carries its category and whatever sparse photometric fields it has.

Schema (additive, optional)

• Two new optional top-level blocks. exit_sign carries the legend (text, color, height, and the externally-illuminated stroke/letter geometry), illumination mode and technology, face count, directional indicators, rated viewing distance, and the mode-specific photometrics (face luminance, face illuminance, contrast ratio, tritium rated life, photoluminescent charging illuminance). emergency carries emergency_role and power_source (both required within the block), battery duration, chemistry, and self-test, the distinct emergency-mode lumen output and input power, remote-head capacity, and an emergency-mode photometry-file reference. Both blocks are absent unless authored; an empty exit_sign block is valid, and an emergency block requires its two discriminators.
• Ten new taxonomy vocabularies: ExitSignIlluminationMode, ExitSignIlluminationTechnology, LegendColor, ExitSignFaceCount, ExitSignDirectionalIndicator, RatedViewingDistance, EmergencyRole, EmergencyPowerSource, BatteryChemistry, and EmergencySelfTestCapability.
• An end_mount token added to MountingType (end mounting is a standard ordering option on the reference exit-sign series).

Grading

• Per-class profiles, derived from the existing core field product_family.primary_category. An exit_sign grades against the sign dataset (the architectural-photometry rows are not-applicable); an emergency_luminaire grades against the normal profile minus luminaire efficacy, plus the emergency gates; every other category is unchanged. 18 new class-gated rubric rows (4 core, 12 standard, 2 full) and 13 new non-gating enrichment rows carry the sign and emergency data.
• The sign full tier is anchored on UL 924 test-report depth: a lab-measured face luminance or illuminance carrying test_report provenance, partitioned by illumination mode so every sign has exactly one applicable full row.
• ul_924 now satisfies the core safety-listing gate (it joins both the North-American and the general acceptance sets) and, for a North American dedicated-class product, a dedicated UL 924 listing core row. This can only turn a fail into a pass and moves no existing record, since none carries ul_924. UL 924 is read from the attestation ledger; there is no ul_924_listed boolean.
• The gates are US-first, anchored on UL 924 and the NFPA 101 / IBC evidence base. International emergency standards are deferred (see ROADMAP.md).

Examples

• Three new real exit-sign reference records from published Cooper Sure-Lites and AtLite series: cooper-sure-lites-lpx7sd (self-powered polycarbonate exit, grades core), cooper-sure-lites-es61src (AC-only edge-lit exit, grades standard), and cooper-atlite-auxswhsd (self-powered NYC-compliant edge-lit exit, grades standard, its ul_924 attestation backed by two attached UL Certificates of Compliance). As with every reference record, source files are referenced by content hash and not committed.
