B-XSZL-corpus-repoint-post-sdlc-move
The apps/sdlc to solutions/ontological move deliberately left 207 docs/planning files citing old paths, matching the precedent from the plugin/ to apps/sdlc move. Sweep the corpus prose: update live/normative citations, leave genuinely historical narrative (completion notes, closed tasks) as history. One generated line in docs/index.md self-corrects with the sweep. Mechanical, low risk, no schema changes.
