FINVECTOR · DATA QUALITY AUDIT · NOTE 07

A stocking week is not a stocking day

An evidence-classification example showing why published date precision must survive the ranking pipeline.

DECISION READING

The audit finding.

Water A can still have useful recent evidence, but the interface must say “week of” rather than fabricate a precise event date. Precision is part of the evidence, not a display detail.

HUMAN ACCOUNTABILITY + AI USE RECORD

The owner is accountable; the technical checks were AI-assisted.

The TOOOLBOX site owner authorized the publication scope and remains the correction contact. AI assistance was used for drafting, implementation, arithmetic recomputation, and source-link checks. This record does not claim line-by-line human fact-checking or licensed professional review.

  1. Tested the classification rule with week-level and exact-day records without assigning a fabricated midpoint.
  2. Kept planned and reported-completion evidence as separate statuses throughout the example.
  3. Checked that freshness is not extended into a survival, catch, access, regulation, or safety claim.

BOUNDARIES

What passed data checks still cannot prove.

  • This case does not identify a specific trip destination.
  • Agencies can revise schedules and reports.
  • Users must verify current regulations, closures, and access before departure.

SENSITIVITY

Failure modes to retest.

  • Scheduled and completed stocking records should be labelled separately.
  • A recent record can be outweighed by closures, unsafe weather, or uncertain access.
  • Stocking quantity is not directly comparable when agencies report different life stages or units.
