How to read this
The stream below stacks each month's coverage by the lens you choose: Tone (how the press frames the story — promotional, skeptical, critical, or neutral), Story type (launches, funding, lawsuits, partnerships…), or Stage — how far the reported claim has gone: speculation → announcement → launch → results.
Taller bands mean more coverage that month; the dots beneath mark notable non‑neutral events. Every signal is sourced and dated.
How this is counted — why the article numbers differ
39 articles mention Mythos 5.1 across the corpus. The coverage make-up above is measured on the 26 of them that were read into dated, classified coverage items — and one article can produce more than one item, because story type, claim stage and framing are read separately.
