Editorial policy.
Every PieceID guide must make its sources, comparison boundary and uncertainty visible. The objective is a better evidence file—not a dramatic verdict.
Source hierarchy.
- Primary sources: current manufacturer pages, official collection material and official service information for present-day context.
- Qualified secondary sources: specialist or archival material when primary historical documentation is unavailable, labelled by source type.
- Seller-supplied material: preserved as a claim, not converted into verified fact.
A current product page is never presented as a complete historical archive. When a comparison depends on period, model, reference or material, the guide says so.
Four evidence labels.
| Label | Meaning |
|---|---|
| Observed | Directly visible in the supplied material without interpretation. |
| Source-dependent | A comparison that depends on the relevance and quality of an identified source. |
| Unresolved | Evidence is missing, ambiguous or not comparable. |
| Specialist review | A physical, technical or high-stakes question outside the guide’s limits. |
PieceID avoids arbitrary percentages, “guaranteed authentic” language and conclusions based on a single identifier.
Dates and corrections.
Substantive guides display an update date and name external sources near the relevant scope statement. When a source changes, the guide should be reviewed rather than silently treating the new page as evidence for older configurations.
Corrections should preserve the distinction between a factual correction, expanded context and a changed editorial interpretation.
Independence and commercial boundaries.
Referenced brands do not approve PieceID’s guides. No brand relationship, expert reviewer, certification, customer outcome or product availability is invented. Commercial relationships, if introduced later, must be disclosed without changing evidence labels or conclusions.
