# Tasks — restore-crypto-fold-keys-vault

## 1. Pre-move audit

- [ ] 1.1 Confirm no consumer outside `crypto-vault`'s own tests imports `ChainSigner`
- [ ] 1.2 List every `@suaveplan/crypto-keys` and `@suaveplan/crypto-vault` consumer with `grep -rln` (expected: only `auth/auth`)
- [ ] 1.3 Snapshot test count + coverage across the three packages so post-move parity is measurable

## 2. Move files (preserve git history with `git mv`)

- [ ] 2.1 `git mv crypto-keys/src/keypair/* crypto/src/keychain/keypair/`
- [ ] 2.2 `git mv crypto-keys/src/keychain/* crypto/src/keychain/storage/`
- [ ] 2.3 `git mv crypto-vault/src/mnemonic/* crypto/src/vault/mnemonic/`
- [ ] 2.4 `git mv crypto-vault/src/vault/* crypto/src/vault/legacy-vault/`
- [ ] 2.5 Merge `crypto-keys/src/errors/codes/*` and `crypto-vault/src/errors/codes/*` into `crypto/src/errors/codes/` (resolve any code collisions; document in the diff)
- [ ] 2.6 Walk every internal import in moved files and re-point relative paths to the new home
- [ ] 2.7 Update `crypto/src/index.ts` to re-export the moved surface from the new locations

## 3. Delete `ChainSigner`

- [ ] 3.1 `git rm -r crypto-vault/src/chain-signer/`
- [ ] 3.2 Confirm no remaining import of `ChainSigner` anywhere in `packages/`

## 4. Delete the two old packages

- [ ] 4.1 `git rm -r packages/crypto/crypto-keys/`
- [ ] 4.2 `git rm -r packages/crypto/crypto-vault/`
- [ ] 4.3 Run `bun install` to refresh the workspace lockfile

## 5. Migrate consumers

- [ ] 5.1 `auth/auth/package.json`: remove `@suaveplan/crypto-keys` dep; add `@suaveplan/crypto` dep
- [ ] 5.2 Codemod-update every `auth/auth/src/**/*.ts` import from `@suaveplan/crypto-keys` to `@suaveplan/crypto` (subpath form may need adjustment to match the new layout)
- [ ] 5.3 If any other consumer surfaces in the audit (Section 1.2), repeat for it

## 6. Manifest + docs

- [ ] 6.1 Update `CLAUDE.md` package list: remove `crypto-keys`, `crypto-vault`
- [ ] 6.2 `bun scripts/folder-reorg/generate-manifest.ts` to refresh `MANIFEST.md`

## 7. Verification gates

- [ ] 7.1 `bun run check` — Biome 0/0/0 across monorepo
- [ ] 7.2 `bunx turbo lint typecheck test --filter=@suaveplan/crypto` green
- [ ] 7.3 `bunx turbo lint typecheck test --filter=@suaveplan/auth` green
- [ ] 7.4 `bunx turbo test:coverage --filter=@suaveplan/crypto` 100/100/100/100 over folded modules
- [ ] 7.5 `bunx turbo test --filter=...@suaveplan/crypto` (dependent sweep) green
- [ ] 7.6 `grep -rln "@suaveplan/crypto-keys\|@suaveplan/crypto-vault" packages/` returns zero (excluding `archive/`)

## 8. Archive

- [ ] 8.1 Fold spec delta into `openspec/specs/crypto/spec.md`
- [ ] 8.2 Delete `openspec/specs/crypto-keys/` and `openspec/specs/crypto-vault/` if those dirs exist
- [ ] 8.3 Move `openspec/changes/restore-crypto-fold-keys-vault/` → `openspec/archive/<yyyy-mm-dd>-restore-crypto-fold-keys-vault/`
