education.final_grade

Three distinct suites: educational examples on the calculator page, this legacy regression count (26/26 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 1.1.1. CVP 1.0.0-proposed. 1/1 golden · 12/12 CVP boundary · 4/4 invalid · 8/8 property · 2/2 metamorphic · 1/1 cross-interface · 6/6 CVP contract. digest abffb9d33246.

• Golden (oracle-backed) 1 / 1
• CVP boundary 12 / 12
• Invalid input 4 / 4
• Property 8 / 8
• Metamorphic 2 / 2
• Cross-interface 1 / 1
• CVP contract 6 / 6
• Interfaces PASS · UI (SSR) / REST / MCP
• Interface claim ui-ssr is query-result HTML, not a live browser session.
• Assurance Engineering

• 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 sha256:548a9acb12e46491968636cf4991a6f7ab8a701719afbde49b6e02c3921c9df2 · Output schema sha256:2fa2caf68de0f94e8f23cae378eed36318bc3b0edbb0cdebcadfd2b07cd7e1ba · 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

• Category weights are percentages that should total about 100% including remaining work.
• Need on final / Overall after final: Current must exclude the final. Do not enter a current grade that already counts the final as 0%.
• Weighted course: enter category grades and weights as they actually appear in the syllabus or LMS for completed work.
• No curve, drop-lowest, or extra credit unless you adjust inputs yourself.

Limitations

• Need on final / Overall: Current must exclude the final (pre-final grade). Do not enter an LMS current that already counts the final as 0%.
• Weighted: enter category grades and weights as they actually appear for completed work; remaining weight is optional.
• W is percent (40); w = W/100 is the fraction form. Do not mix W and w in one expression.
• Need on final with W = 0 → status invalid, code WEIGHT_REQUIRED (not a number).
• Points mode total ≤ 0 → TOTAL_POINTS_REQUIRED. Final points > total still computes and warns POINTS_EXCEED_TOTAL.
• Letter cutoffs / GPA points are a reference example, not part of the calculation model.
• Planning estimate only — not an official transcript. No curve, drop-lowest, or extra credit unless you adjust inputs.
• Engine aliases current/goal/W/finalScore/totalPoints are accepted at runtime; prefer share-URL field names in schemas.
