 ## Accumulated Context
 
 ### Decisions
 
-- Stay with SQLite -- single-user app, Postgres adds unnecessary complexity
-- Lucide Icons for category icons -- best outdoor/gear coverage
-- categoryId on threads is NOT NULL with FK to categories -- every thread belongs to a category
-- [Phase 04]: Modal dialog for thread creation instead of inline form -- cleaner UX, supports category selection
-- [Phase 04]: Educational empty state with numbered workflow steps -- helps new users understand planning flow
-- [Phase 04]: Pill tab segment control for Active/Resolved -- replaces checkbox, more intuitive
-- [Phase 05]: Image bug root cause: Zod schemas missing imageFilename -- validator silently stripped it from payloads
-- [Phase 05]: Inline SVGs instead of lucide-react -- only 3 icons needed, avoids dependency
-- [Phase 05]: Setup detail page only uses ItemCard grid -- no separate thumbnail component needed
-- [Phase 06]: ALTER TABLE RENAME COLUMN for SQLite migration instead of table recreation
-- [Phase 06]: Applied migration via Bun SQLite API since drizzle-kit requires interactive input
-- [Phase 06]: 119 curated Lucide icons across 8 groups for gear coverage
-- [Phase 06]: Native HTML select cannot render React components -- category selects show name only
-- [Phase 06]: iconData.ts renamed to iconData.tsx -- contains JSX, required for production build
