Tasks — restore-crypto-cleanup-duplicates

1. Snapshot

• 1.1 Build @suaveplan/crypto and capture public symbol set from dist/index.d.ts to tests/before.dts.txt

2. Rewrite the barrel

• 2.1 Rewrite crypto/src/index.ts so every primitive-surface symbol re-exports from @suaveplan/crypto-core (typed export { ... } from "@suaveplan/crypto-core")
• 2.2 Verify the symbol set still matches by re-running the dist diff

3. Delete duplicate modules

• 3.1 Delete crypto/src/aead/ (5 files)
• 3.2 Delete crypto/src/agree/ (6 files)
• 3.3 Delete crypto/src/auth-box/ (5 files)
• 3.4 Delete crypto/src/sealed-box/ (5 files)
• 3.5 Delete crypto/src/sign/ (9 files)
• 3.6 Delete crypto/src/primitives/ (10 files)
• 3.7 Delete crypto/src/engines/ (6 files)
• 3.8 Walk every internal import in the retained crypto/src/ modules and re-point any reference that resolved into a deleted directory at @suaveplan/crypto-core (subpath imports as needed)

4. Trim package.json

• 4.1 Audit crypto/package.json deps: keep crypto-core, bitpacker, error, types, tslib, zod; remove any of crypto-cipher, crypto-curve, crypto-hash, crypto-utils that are no longer directly imported by retained modules
• 4.2 Re-run typecheck to verify no transitive-dep gap

5. Verification gates

• 5.1 bun run check — Biome 0/0/0 across monorepo
• 5.2 bunx turbo lint typecheck test --filter=@suaveplan/crypto green
• 5.3 bunx turbo test:coverage --filter=@suaveplan/crypto 100/100/100/100 over retained modules
• 5.4 bunx turbo build --filter=@suaveplan/crypto produces a dist/index.d.ts byte-identical to the pre-change snapshot
• 5.5 bunx turbo test --filter=...@suaveplan/crypto (dependent sweep) green
• 5.6 OpenSpec conformance script clean for @suaveplan/crypto

6. Archive

• 6.1 Fold spec delta into openspec/specs/crypto/spec.md (preserves the new "primitives sourced from crypto-core" requirement)
• 6.2 Move openspec/changes/restore-crypto-cleanup-duplicates/ → openspec/archive/<yyyy-mm-dd>-restore-crypto-cleanup-duplicates/
