Groups documentation produced during 2026-05-28 brain-retro session: retro notes 8 (carryover) and 9, self-retrospect 1, sanity check JSON, three Phase plans for router-hooks fixes. All implementation already pushed in earlier commits — this commit groups artifact metadata. Plus typo fixes in self-retrospect (agregatov, seryj) and cspell vocab extensions for session-specific terms (PAMYATKA / procs / russian verbs). Pure documentation. No code, no normative drift.
