Content corrected against upstream docs, deployed-version source and the live config: retention/GC semantics (untagged manifests including digest-only pull-through entries are GC-eligible; keepUntagged is v2.1.19+, not deployed), warm-cache guarantees (tag pulls revalidate upstream per open issue; digest pulls serve locally), retry arithmetic (buildah --retry counts retries: 16 max, not 12), five-upstream flat-namespace routing stated as observed risk with a proposed prefix redesign, auth-canary design validated against longest-match policy precedence with the Docker-client caveat, coalescing reframed from deadlock to design with the restart as recovery-not-root-cause. Adds fact panel, contents, failure-mode and cache test matrices, decision table, open verification register and primary-source references. Front-end: grid full-bleed (no viewport units - no scrollbar overflow), shell-level skip link, real 1600x872 intrinsic dims injected from bytes, lazy below-fold plates, AA code-comment contrast, scene engine rewritten (IO-gated, rAF-coalesced, live reduced-motion, hidden-tab pause, zero guards). Assembler: per-page gates plus mirror-specific required/banned content assertions. README describes the multi-page site honestly.
