Web archive engineering notes

Field notes from maintaining large content archives — collected here as plain markdown so they're reusable beyond the sites they were written for.

Notes included

• sitemap-chunk-verification.md — keeping a sitemap index and its chunk generator on one source of truth; incident write-up from a ~462K-URL archive (RHentai, 420K+ galleries / 30K+ waifus / 14K+ videos). Covers the "index says 50 chunks, generator makes 43" failure mode.
• upsert-merge-pipeline.md — hourly crawl → staging → single-statement ON CONFLICT ... IS DISTINCT FROM merge, and the two Postgres footguns that bit us (unqualified columns in the WHERE, row-by-row updates at volume).
• generation-recipe-sidecar.md — storing AI generation settings (base model, sampler, steps, CFG, prompt, LoRA stack) as structured data at ingest time. Pattern used by BedreamAI, a 2.4M+ model library for Stable Diffusion / SDXL / Flux.

Why publish these

Large-archive SEO and ingestion problems are solved in private over and over. These notes are the parts we wish someone had written down before we hit them.
