F01 / VERIFIED-LIKE FACT PATTERNARCHIVE
The blue benches were installed
In fictional Rillport, the transit board says six blue benches were added at the eastern terminus.
SIMULATED GRADE A · Documented within story
Open evidence dossier ↗
Fictional source: Municipal notice + dated site photographs
Within this fiction: a signed installation log, six timestamped site images, and a budget line match. This supports installation, not an inference that every rider feels safer.
What else is needed? An independent site visit and an accessibility inspection would test whether the benches serve intended users.
F02 / VERIFIED-LIKE FACT PATTERNARCHIVE
A library changed its opening hours
The invented Mosswick Library extended Thursday closing from 6 to 8 p.m. for a four-week trial.
SIMULATED GRADE A · Documented within story
Open evidence dossier ↗
Fictional source: Public library schedule + staffing memo
A posted trial schedule, staffing roster and dated announcement align. No long-term policy change is established.
What else is needed? After the trial, compare actual opening times and published evaluation rather than extrapolating permanent change.
F03 / VERIFIED-LIKE FACT PATTERNARCHIVE
A footbridge was inspected
Engineers in the imaginary town of Alderfen filed a routine inspection report about the North Walk footbridge.
SIMULATED GRADE A · Documented within story
Open evidence dossier ↗
Fictional source: Engineering report + archive copy
A dated inspection report and independent archive copy exist in the fictional packet. It records minor repairs, not an emergency closure.
What else is needed? Confirm author, scope and whether follow-up repairs were completed.
O01 / OPINIONARCHIVE
The night bus deserves more space
One columnist argues a city budget should favour night buses over decorative lighting.
SIMULATED GRADE B · Value judgment; check premises
Open evidence dossier ↗
Fictional source: Signed editorial
The argument states a clear value priority and offers a hypothetical allocation. It is not a factual report of a city decision.
What else is needed? A full budget, ridership distribution and effects on street safety would make the trade-off less abstract.
O02 / OPINIONARCHIVE
Silence should count as public infrastructure
A fictional essayist calls for quiet zones in crowded transport hubs.
SIMULATED GRADE B · Value judgment; check premises
Open evidence dossier ↗
Fictional source: Attributed essay
The claim is normative: quiet is presented as a public good. There is no asserted measurement of noise effects here.
What else is needed? Consider accessibility needs, enforcement burdens and who gets to define acceptable sound.
O03 / OPINIONARCHIVE
Every mural is also an argument
A critic believes a new painted wall should invite disagreement rather than automatic civic pride.
SIMULATED GRADE B · Value judgment; check premises
Open evidence dossier ↗
Fictional source: Culture column
The writer describes a position rather than independent evidence of a community consensus.
What else is needed? Hear from residents, the artists and those whose spaces are represented.
P01 / PROMOTIONAL COPYARCHIVE
The lantern that will fix your evenings
A shop in fictional Juniper Quay offers a lantern advertised as the secret to calmer nights.
SIMULATED GRADE C · Sales claim; independent testing absent
Open evidence dossier ↗
Fictional source: Seller advertisement
The copy includes a product photograph and a price but no comparative test showing improved wellbeing.
What else is needed? Check safety certification, return terms and independent product testing; decide whether the claim is measurable.
P02 / PROMOTIONAL COPYARCHIVE
Only nine seats left at the Idea Salon
An imagined event page urges immediate booking for a community discussion night.
SIMULATED GRADE C · Seller-controlled scarcity
Open evidence dossier ↗
Fictional source: Event organiser landing page
An event date, venue and payment page exist in the fiction. The scarcity claim is unverified and changes without notice.
What else is needed? Ask for capacity, refund policy, organiser identity and evidence of remaining seats.
P03 / PROMOTIONAL COPYARCHIVE
Discover the most trusted tea in town
A fictional tea brand uses a gold seal and a satisfaction promise to imply broad acclaim.
SIMULATED GRADE C · Self-attested superlative
Open evidence dossier ↗
Fictional source: Brand packaging copy
The seal is its own design. No independently sampled consumer survey is supplied.
What else is needed? Define “most trusted”, examine survey methods and compare similar products.
A01 / AMBIGUOUS REPORTARCHIVE
A humming sound near the reservoir
Several residents of invented Fenlow report an intermittent hum after dusk; its source is unknown.
SIMULATED GRADE B · Observation credible; cause unknown
Open evidence dossier ↗
Fictional source: Unconfirmed local observations
Multiple accounts mention a sound, but reports were collected informally and no calibrated recording or cause analysis exists.
What else is needed? Independent measurements across nights, location mapping and alternative explanations.
A02 / AMBIGUOUS REPORTARCHIVE
The market queue got shorter
A neighbourhood post claims that wait times fell after signs were moved at the fictional Glass Market.
SIMULATED GRADE C · Direction untested
Open evidence dossier ↗
Fictional source: Community post + one photograph
A photograph shows moved signs, not a reliable before-and-after waiting-time comparison.
What else is needed? Sample wait times across days and hours; check crowd size and staffing.
A03 / AMBIGUOUS REPORTARCHIVE
Students say the workshop helped
A small informal group at an invented arts school reports feeling more confident after a weekend workshop.
SIMULATED GRADE B · Experience reported; effect uncertain
Open evidence dossier ↗
Fictional source: Informal participant comments
Self-selected comments suggest genuine experience, not controlled evidence of lasting impact or general benefit.
What else is needed? Participant count, nonresponse, comparison conditions and longer-term follow-up.
V01 / PERSONAL VIGNETTEARCHIVE
Someone saved me a seat
A fictional commuter describes a stranger quietly moving a bag so they could sit after a long shift.
SIMULATED GRADE B · Personal testimony; not a trend
Open evidence dossier ↗
Fictional source: First-person fictional diary
The narrated experience is not independently checkable. Its emotional meaning does not require it to prove a population-wide trend.
What else is needed? For the personal account, seek consent and context; for a wider generalisation, use representative data.
V02 / PERSONAL VIGNETTEARCHIVE
The repaired kite
A child in invented Harrowmere writes about a grandparent repairing an old kite rather than buying a new one.
SIMULATED GRADE B · Meaningful narrative; not proof
Open evidence dossier ↗
Fictional source: Fictional personal letter
This is an explicitly imagined memory meant to express care; there are no population or economic claims.
What else is needed? Distinguish the value of the story from broader claims about repair cultures.
V03 / PERSONAL VIGNETTEARCHIVE
The apology at closing time
A shopkeeper recounts telling a colleague they had been unfair during a busy afternoon.
SIMULATED GRADE B · Personal account; limited scope
Open evidence dossier ↗
Fictional source: Fictional diary entry
The apology may matter personally, but no outside witness or corroborating record is supplied in this invented scene.
What else is needed? If evaluating a broader claim about workplace change, look for repeated behaviour and the colleague’s account.
U01 / UNSUPPORTED CLAIMARCHIVE
All clocks in Fenlow run six minutes fast
A dramatic anonymous message insists the entire fictional district is manipulating public time.
SIMULATED GRADE D · No supporting evidence
Open evidence dossier ↗
Fictional source: Anonymous chain message
No time standard, cross-checkable clocks, documents or mechanism are offered. Universality makes this easy to test and the packet offers nothing.
What else is needed? Compare independently synchronised clocks, define where and when, and demand a testable mechanism.
U02 / UNSUPPORTED CLAIMARCHIVE
One song doubled everyone’s memory
A viral-style post claims an unnamed melody produced an immediate cognitive breakthrough for all listeners.
SIMULATED GRADE D · No supporting evidence
Open evidence dossier ↗
Fictional source: Unattributed repost
No author, sample, controls, measurements or independent replication. A universal claim outruns the material.
What else is needed? Original study, operational definition of memory, comparison group, effect sizes and replication.
U03 / UNSUPPORTED CLAIMARCHIVE
The moon chose the council’s budget
A mysterious fictional flyer attributes an entire municipal budget to the phase of the moon.
SIMULATED GRADE D · No supporting evidence
Open evidence dossier ↗
Fictional source: Unsigned flyer
A metaphor may be intended, but the flyer supplies no records linking a celestial event to the decision.
What else is needed? Meeting minutes, transparent spending records and evidence of actual decision mechanisms.
