Close readings of first-party writing from the labs and companies the money runs through.
First-party writing from the labs and companies the money runs through — posts that are moves in the market they describe. A benchmark write-up from the team selling the tool it benchmarks is not reporting on the field; it is the field, announcing itself.
A piece here carries the same parts as a recap, in the same order: the claims the post makes, each one quoted, graded and assessed, and the argument chains they form — written so that someone who never opens the post can argue with it, claim by claim. What the grading must add for this source class: which claims rest on the author’s own product, and what survives that discount. Not editorial distance — the author has a position and says so. Not peer review — nobody reviewed it and nobody will. The third thing: a primary source with skin in the game, read accordingly.
Conventions
Followed, not enforced. Nothing here checks them.
- Every piece analyses exactly one post, declared as its `article:` source.
- The title is the original's title, so a piece is findable by the thing it analyses rather than by what someone decided to call the analysis.
