Asset Weight and Duplication

Fixtures covering minification detection on CSS/JS/HTML, duplicate and identical resource grouping, single-asset and combined per-category size thresholds, same-origin request counting, and enormous-network-payload detection.

Fixtures that let a crawler prove it measures page weight from response bytes: per-resource sizes from exact Content-Length headers, byte-identity grouping across URLs, and per-category budget sums.

Families:

• Minification: a pretty-printed HTML page linking a stylesheet and a script served as UTF-16LE with BOM — the encoding is load-bearing because the product’s minified-checker reinterprets raw bytes as UTF-16 chars, so ordinary UTF-8 files always report “minified”.
• Oversized single stylesheet: a committed 20,480-byte minified stylesheet over the 14.5 KB threshold.
• Duplicates: the same stylesheet and script served byte-identically under ?v=1/?v=2 query variants.
• Identical resources: byte-identical stylesheet and script pairs at URLs whose paths differ beyond the query string.
• Combined budgets: pages whose CSS (583,680 B), JS (573,440 B), image (1,081,344 B), and webfont (245,760 B) totals each exceed their budget while every individual asset stays under its per-asset threshold.
• Request count: one page referencing 36 distinct same-origin subresources (30 tile images, 6 deferred no-op scripts) totalling ~10 KB.
• Enormous payload: a direct-entry-only page referencing two streamed 2,621,440-byte binaries, with a concurrency cap of 4 and deterministic 429 + Retry-After overflow behaviour.

Size-threshold fixtures declare the compression-control capability: an environment whose ingress rewrites Content-Encoding/Content-Length reports them unavailable rather than corrupting the byte targets. Everything is safe or moderate except the enormous-payload trio, which is risky and direct-entry only so casual crawls never trigger the expensive generators.
