Content quality and language

Calibrated word counts, readability and sentiment extremes, template subtraction, rendered word divergence, multilingual spelling, and a near-duplicate similarity gradient.

Calibration fixtures for content analysis. Every page carries committed, frozen copy whose stated numbers — word counts, readability bands, sentiment sums, seeded misspellings, and similarity percentages — never change for the life of the route. Body markers in this group are HTML comments, because visible marker text would change the word counts and register as spelling errors.

Families:

• Word counts: exactly 120, 750, and 1,200 content words, pinning the 501 to 900 word bin from inside and above.
• Readability and sentiment: prose designed deep inside the very easy and very difficult Flesch-Kincaid bands, and reviews seeded with AFINN vocabulary far beyond the very positive and very negative cut-offs.
• Template subtraction: four siblings sharing a byte-identical 150-word nav and aside template over 200, 300, 400, and 500 main-content words.
• Rendered divergence: a browser fixture whose raw body holds exactly 150 content words and whose inline script appends exactly 100 more.
• Spelling: eight languages plus a regional-code fallback page and a custom-dictionary trap, each seeding five documented misspellings and an alt-text probe that must contribute nothing.
• Similarity gradient: a 1,000-word base and three variants retaining 95, 85, and 70 percent of its paragraphs.

Every route except the rendered-divergence browser fixture sits in the default sitemap, so one crawl discovers the whole similarity cluster and the template family together.
