Lifetime totals (count · distance · ascent · elapsed time) + a last-4-weeks count on the profile, viewer-scoped (public-only for visitors, full for the owner). Design records the cost decision: compute on the fly with a single aggregate over stored columns on the owner_id-leading indexes (cheap even for power users) — no cache table, no schema change — with a documented escape hatch to a user_activity_stats cache if profiling ever shows it's hot. Validates with `openspec validate --strict`. Specs only; no code. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |
