dev 4427837e7a Mistake tagging: per-question why-lost form plus dashboard rollup ... Result page shows a why-lost row (concept gap / calculation slip / misread / out of time / blind guess) on every wrong or blank question. POST /result/:attempt/tag/:qid toggles one tag; ownership checked, vocabulary enforced server-side. Dashboard gains a 'why you lose marks' section aggregating tags across all submitted attempts. Verified live: tag persists, rollup renders.		2026-10-12 12:44:30 +05:30
