Retained observations
Complete point observations retained from the archive. They count as witnessed price-days and participate in the longitudinal record.
Method & coverage
Wasitever measures exact retailer offers over time. Every verdict is bounded by what we actually witnessed, and every important limit stays visible beside the result.
Latest coverage is partial · evidence through
The pipeline
A tool page is the end of a traceable measurement process, not a rewritten retailer card.
Product, configuration, retailer listing, retailer, and channel form one identity. A bare tool, kit, and bundle never share a price record.
Price and availability observations are stored with their source batch and exact time. Failed or incomplete coverage cannot prove absence.
Price-days accumulate. Gaps remain gaps. Retailer reference-price claims stay separate from prices Wasitever actually witnessed.
The canonical algorithm applies one maturity and verdict policy. Qualifying events enter an append-only journal before any publication surface can use them.
Evidence model
All three can be real evidence; they do not carry the same analytical weight.
Complete point observations retained from the archive. They count as witnessed price-days and participate in the longitudinal record.
New point observations accruing through the active collection pipeline. They carry source-batch and coverage receipts.
A durable witnessed high or low with a date. It appears as a detached mark, never a continuous curve, and never counts as a price-day.
Claim permissions
More ambitious language requires more evidence. Pages cannot promote themselves into a stronger claim.
Fewer than 7 price-days or less than a 14-day span
7–29 price-days spanning at least 14 days
At least 30 price-days
A continuous 12-month record
Live scope
Today’s limits are stated directly. New retailers and brands will enter as parallel scopes under the same evidence contract.

One retailer’s record does not establish another retailer’s history.
Corrections
When a published fact is wrong, its page states the old value, corrected value, date, and cause. Evidence and canonical deal events are append-only; a correction supersedes a bad publication instead of silently rewriting history.
Reproducibility
Pages identify the evidence timestamp, export manifest, algorithm version, and build. Two builds from the same accepted snapshot must produce byte-identical output.
Placement policy
No one can pay for a verdict or position. Qualifying offers are ordered by the canonical evidence ranking.
