Development record

The 05-internals index and the 04-surfaces row still call shipped site capabilities design targets, contradicting 10-site.md. 05-internals/README.md row 10 says the check gates, the explorer pages and the deploy workflow are design targets, and 04-surfaces/README.md row 22 says the deploy workflow remains a design target — but 10-site.md marks only the abcdev.app MkDocs root as the design target, abcd site check is registered shipped in surface.json, the explorer shipped (itd-136), and the deploy workflow ships (adr-48 accepted, release.yml calls site.yml, CHANGELOG 0.6.6). Both index cells are stale surviving copies of the earlier all-staged claim; outside the release-gate crosscheck's pinned briefDocs corpus, so no gate catches the record-vs-record contradiction. Fix: align both cells with 10-site.md.
