electrical.energy_consumption

Three distinct suites: educational examples on the calculator page, this legacy regression count (16/16 golden + boundary), and the CVP verification suite below. They are not the same number. Property, metamorphic, round-trip, O3, and interface statuses/checks are recorded in the CVP Manifest . SKIP (0/0) means that suite has no published vectors.

CVP verification suite

Protocol checks from the Evidence Manifest. Distinct from the legacy regression suite above. Verification revision 2026-10-28.meta-metrics-v2. Calculation version 1.4.2. CVP 1.0.0-proposed. 2/2 golden · 3/3 CVP boundary · 5/5 invalid · 4/4 property · 2/2 metamorphic · 2/2 cross-interface · 6/6 CVP contract. digest 66fea25f438c.

• Golden (oracle-backed) 2 / 2
• CVP boundary 3 / 3
• Invalid input 5 / 5
• Property 4 / 4
• Metamorphic 2 / 2
• Cross-interface 2 / 2
• CVP contract 6 / 6
• Interfaces PASS · UI (SSR) / REST / MCP
• Interface claim ui-ssr is query-result HTML, not a live browser session.
• Verified scope core energy calculation (W × h / 1000 → kWh)
• Assurance Engineering
• Deferred UI daily/month/year projections (×30 / ×365)

• release artifacts aligned PASS
• schema output required declared PASS
• schema valid input executes PASS
• engine success output validates schema PASS
• schema rejects incomplete input PASS
• rest success payload validates schema PASS

Input schema sha256:4fbea79f291b0be2d402bcdf35e1ee32958364497986406299f9bc995d16ad71 · Output schema sha256:513207640dd3f6145f0da67434085aa12ebf3bc9a84d9250d53dda64ead66e47 · Build-time SHA-256 digests prove published artifacts agree with each other (release_integrity.scope=workspace). Production attestation GETs canonical URLs twice (public/cached view and origin), including Capability HTML, via npm run attest:production --write (published at /.well-known/calculatorx-production-attestation.json) and fails if the public Capability page advertises a different calculation_version. This is artifact consistency, not an independent immutable release log.

Assumptions

• Constant power over the stated hours.
• Month = 30 days, year = 365 days in daily UI projections (presentation-only).
• User converts kW→W when needed.
• W ≥ 0 and hours ≥ 0 (consumption, not signed energy flow).

Limitations

• Assumes constant power over the stated hours
• W and hours must be ≥ 0 (VALUE_MUST_BE_NON_NEGATIVE)
• UI daily month/year projections are presentation-only; engine returns period kWh
