Phase 121 — SMSPLANET Conversation + Notifications:
- migration 20260512_000110 adds smsplanet conversation + notifications tables
- src/Modules/Sms (SmsConversationService, SmsMessageRepository, SmsplanetWebhookController)
- src/Modules/Notifications (Repository, Controller, ApiController)
- order SMS tab, notification center, sender mode, inbound webhook
- public notifications.js + layouts/app.php integration

Phase 122 — SMSPLANET Default SMS Footer:
- migration 20260512_000111 adds smsplanet_integration_settings.default_footer
- footer appended to test SMS and order SMS, validated against 918 char limit
- settings textarea + compact order SMS note when footer configured

Bundled (could not split per-phase without hunk staging):
- routes/web.php (also carries Phase 118 fakturownia redirects)
- DOCS/{ARCHITECTURE,DB_SCHEMA,TECH_CHANGELOG}.md (118 + 121 + 122 entries)
- .paul/codebase/{architecture,db_schema,tech_changelog}.md (118 + 121 + 122)
- .paul/STATE.md, ROADMAP.md, changelog/2026-05-12.md (UNIFY closure)
