Builds out the Cards spinoff end-to-end so the standalone app at
cards.mana.how shares its data layer with the in-mana cards module
through a single pure-utility package.
Why a spinoff and not just a deeper module: per the GUIDELINES, Cards
gets its own brand + URL while reusing mana-auth, mana-sync, and the
mana-credits/billing stack. The in-mana module under mana.how/cards
stays untouched as the integrated experience.
Phase 0 — mana-modul foundation
• New tables cardReviews + cardStudyBlocks (Dexie v61) + plaintext
classification in the crypto registry.
• LocalCard learns a {type, fields} shape; legacy front/back columns
kept as a back-compat mirror so older builds keep rendering.
• FSRS v6 scheduler + Cloze parser + Markdown render pipeline.
• UI in apps/mana/.../routes/(app)/cards/ gets a learn session
(learn/[deckId]), 4-type card editor, due-counter, markdown lists.
Phase 1 — standalone (apps/cards/apps/web)
• SvelteKit 2 + Svelte 5 + Tailwind 4, port 5180.
• Own Dexie 'cards' DB with a slim 5-table schema.
• Own sync engine: pending-changes hooks, 1 s push / 5 s pull against
POST /sync/cards, server-apply with suppression to avoid ping-pong.
• Auth-Gate via @mana/shared-auth-ui (LoginPage / RegisterPage).
• Encryption hooks at every write/read/apply path, currently no-op
stubs — flipping to real vault-backed AES-GCM is a single-file
change in src/lib/data/crypto.ts.
Shared package — @mana/cards-core
• Pulls types, cloze, card-reviews, FSRS wrapper, and Markdown
renderer out of the mana module so both frontends import from one
source. mana-modul keeps thin re-export shims so consumers don't
need to change imports.
• 19 vitest tests carried over from the mana module.
Server-side wiring
• cards.mana.how added to mana-auth PRODUCTION_TRUSTED_ORIGINS and
its CORS_ORIGINS env (sso-config.spec.ts stays green).
• New cards-web container in docker-compose.macmini.yml (mirrors
manavoxel-web pattern, 128m, depends on mana-auth healthy).
• cloudflared-config.yml repoints cards.mana.how from :5000 (the
unified mana-web container) to :5180. mana.how/cards is unchanged.
Cleanup
• Removed an unrelated 2026-03/04 NestJS+Supabase+Expo experiment
that was lingering under apps/cards/ (apps/landing, supabase/,
.github/workflows, MANA_CORE_*.md, etc.). It predated this plan
and would have confused future readers.
Validation
• svelte-check on mana-web: 0 errors over 7697 files
• svelte-check on cards-web: 0 errors over 3481 files
• vitest on cards-core: 19/19 pass
• pnpm check:crypto: 214 tables classified
• bun test sso-config.spec.ts: 8/8 pass
• vite build on cards-web: green
Not done in this commit (deliberate)
• Real encryption (vault roundtrip) — Phase 2.
• WebSocket-driven pull (5 s polling for now).
• Mobile/landing standalone surfaces — Phase 2/3.
• The actual production cutover on the Mac mini (build, deploy,
cloudflared sync) — config is staged, deploy is a user action.
