What to inspect next
Why the signal is high
This case has multiple accessible sources, a durable visual record, recurring anniversary coverage, and a clear unresolved residue: the later light row is explainable, while the earlier formation accounts are harder to reconstruct cleanly.
Case Verdict
Best current interpretation
Strongly supported
Please help improve it by removing references to unreliable sources , where they are used inappropriately .
Likely explained
This case still needs a stronger dedicated debunk source; current interpretation should remain conservative until better analysis is attached.
Still unresolved
