Haze posts can be current while their numbers are old

Original research record

We connect the OTR data on skyline photographs, Grand Prix visitor questions and NEA measurements. The 10 October NEA advisory gives a 7 PM observation; a weather-service mirror labels the same values 6 PM. That clock difference needs checking. We see a risk when a later repost makes an earlier reading look current. A smoky photograph can establish what a camera showed at a place and time, but cannot replace a PM2.5 measurement or establish an event cancellation.

We would record the reading time separately from the post time. We would use the official next-hour PM2.5 guidance for immediate plans and organisers for event decisions. We would preserve the disagreement between official page clocks until clarified. We expect at least one time-sensitive haze claim in a fixed sample of 20 local posts to need a timestamp or event-status correction over the next 24 hours. This predicts an information-quality issue, not the next PSI level.

Posts may already carry clear timestamps and links. A later official correction may settle the mirror difference. If the sampled posts remain correctly dated and sourced, our claim should be marked a miss.

We would share the observation time beside the number and check the event organiser before spreading a cancellation claim.

Bayesian · what changed the estimate? We give the stated testable claim a 66% subjective estimate over 24 hours. It is uncalibrated and is not a market-direction probability. We raise the weight of dated original statements and concrete events, while keeping repeated OTR files in the same evidence family. de Finetti · are the comparisons fair? We judge the exact event and sample stated here; broader audience belief, adoption and price returns are separate outcomes. Kolmogorov · do the numbers agree? The event estimate and its opposite add to 100%; no measured global denominator or validated base rate is available. The three checks organise the reasoning and do not produce three independent probabilities.

We compare the OTR Database Data across the five-desk editions, research-intelligence records and global-signal verification records. The linked original documents support the underlying facts. The new connection and testable expectation are our inference, rather than a reported result.

Not applicable. This is a social information signal, without an asset-price forecast.

Not applicable to a market direction. We are recording a new synthesis. Earlier versions of the OTR data are used to preserve what was already known; repeated reporting is not counted as a new discovery.

We distinguish discussion, promotion and accusation from original documents, measurements and official decisions. Public comments show that a view was expressed; they do not establish whole-community belief or a measured real-world effect.

We have no frozen, version-matched social-forecast outcome series for this exact claim. We cannot report a historical accuracy percentage. The proposed sample and deadline make this forecast checkable.
