Second edition: five sites merged into one

This site became the canonical ai-factories site. It began as one of five variants built from the same brief by different model/effort pairs as a benchmark; the comparison chose this one as the base and grafted the strongest material from the other four onto it, per a merge spec written before the session that executed itworkspace.

What arrived in the merge. The 90-second argument and the position quote on the front page; the dimmer in chapter 8 and standalone; the playbook with per-stage stop conditions; the staffed/unread figure pair in chapter 3; calibration status chips and per-factory lesson lines on the case studies; the dark-after-design finding stated as a claim; chapter role labels; the provenance footer on every page; a large social card, with a build gate that fails any page missing its metadata.

What happened to the predecessors. The four superseded sites were unpublished. GitHub Pages does not redirect an unpublished project site, so their URLs stopped serving; the old baseline’s chapter slugs redirect here to the corresponding chapters. The built output of all five variants was archived into this repository firstworkspace, and the benchmark itself is written up as a case study — the sole citable record now that the evidence sites are dark.

Recorded, not overwritten. The first edition below stands as published; this entry is the reversal-safe way this log records a change of that size.
