Value
Value governs the semantic correctness of individual fields, histories, representations, calculated values, missingness states, and identity-bearing attributes.
VAL-01 · PARSE-01 — Freeze the Extraction Contract. Define the exact expected field and history schema before production parsing and stop when the authoritative source or target schema drifts beyond that certified contract.
VAL-02 · PARSE-02 — Certify an Exact Entity Before Production. Demonstrate that the parser can identify and correctly extract one exact authoritative entity before applying it broadly.
VAL-03 · PARSE-03 — Populate Values Only from Qualified Evidence. Every non-generated field must derive from qualified evidence belonging to the exact live authoritative entity source.
VAL-04 · PARSE-04 — Never Manufacture Apparent Completeness. Reject fabricated values, guesses, placeholders, generic routes, fake rows, blank substitutes, or misuse of NULL solely to make a record appear structurally complete.
VAL-05 · PARSE-05 — Capture Complete Displayed Histories. When the contract requires an authoritative history, capture every in-scope displayed history row and every required field within each row.
VAL-06 · PARSE-06 — Certify Bounded Representation Variants. Validate parsing across the known bounded variants of the authoritative source rather than assuming one observed representation covers all entities.
VAL-07 · PARSE-07 — Prove Derived Component Values. Accept a value generated by source-side calculation or component logic only when the calculation is source-owned, evidenced, fingerprinted where feasible, and checked against the rendered or otherwise authoritative value.
VAL-08 · PARSE-08 — Reproduce and Repair Parser Misses on the Same Case. When certification exposes a parser failure, repair the parser and rerun the same failing entity until the specific failure is demonstrably resolved.
VAL-09 · PARSE-09 — Isolate Failures Without Converting Them into Successes. Keep unresolved production failures active while allowing independently verified entities to continue through the pipeline.
VAL-10 · PARSE-10 — Treat Genuine Source Omission as Unresolved. When an authoritative source genuinely omits a contract-required value, preserve that condition as unresolved. Do not fabricate the value or claim complete coverage.
VAL-11 · PARSE-11 — Keep Provenance Separate from Data Values. Notes, comments, evidence fields, or provenance metadata may explain why a value is missing or disputed, but they do not substitute for the required value itself.
VAL-12 · PARSE-12 — Preserve Missingness Semantics. Keep numeric zero, Boolean false, empty collection or history, blank content where legitimately meaningful, unknown, not applicable, and genuine source absence semantically distinct.
VAL-13 · PARSE-13 — Validate Representation Fidelity. Validate types, ranges, precision, Unicode, dates, percentages, units, rounding behavior, and other representation rules before declaring a value correct.
VAL-14 · PARSE-14 — Require Cross-Field Identity Consistency. Every identity-bearing attribute—such as source route, source identifier, authoritative identifier, and descriptive identity—must refer to the same entity.
VAL-15 · PARSE-15 — Do Not Scale an Uncertified Parser. Broad ingestion must not begin until both routing identity and parser behavior have passed their required certification conditions.
