Retained observations
Complete point observations retained from the archive. They count as witnessed price-days and participate in the longitudinal record.
Method & coverage
Trust the record, not the banner.
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.

The pipeline
From listing to verdict
A tool page is the end of a traceable measurement process, not a rewritten retailer card.
- 01
Identify the exact offer
Product, configuration, retailer listing, retailer, and channel form one identity. A bare tool, kit, and bundle never share a price record.
- 02
Witness the offer
Price and availability observations are stored with their source batch and exact time. Failed or incomplete coverage cannot prove absence.
- 03
Build the record
Price-days accumulate. Gaps remain gaps. Retailer reference-price claims stay separate from prices Wasitever actually witnessed.
- 04
Publish only what it earns
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
Three classes. Different jobs.
All three can be real evidence; they do not carry the same analytical weight.
Current longitudinal observations
New point observations accruing through the active collection pipeline. They carry source-batch and coverage receipts.
Dated summary facts
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
The maturity ladder
More ambitious language requires more evidence. Pages cannot promote themselves into a stronger claim.
- M0Shows observations and coverage. Publishes no price verdict.
Building
Fewer than 7 price-days or less than a 14-day span
- M1May compare today’s exact offer with its witnessed 90-day reference.
Measured
7–29 price-days spanning at least 14 days
- M2May describe empirical position, including lowest-decile claims.
Deep record
At least 30 price-days
- M3May support claims that explicitly require year-scale evidence.
Long horizon
A continuous 12-month record

Coverage is part of the answer
Today’s limits are stated directly. New retailers and brands will enter as parallel scopes under the same evidence contract.

A verdict is valid only inside its stated exact-offer, retailer, channel, and observed-time scope. One retailer’s record does not establish another retailer’s history.
Corrections
Errors stay visible.
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
Every build carries receipts.
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
Evidence determines placement.
No one can pay for a verdict or position. Qualifying offers are ordered by the canonical evidence ranking. Retailers are compared by witnessed offer facts, never commercial preference. Some outbound links may earn a commission; the ranking and verdict systems receive no affiliate input.
Site measurement
Aggregate, not behavioral.
