Kyle Isom	3b961b5d8a	Step 17: Encryption core — passphrase-only, selective per-file. ... Manifest schema: Entry gains Encrypted, PlaintextHash fields. Manifest gains Encryption section with KekSlots map (passphrase slot with Argon2id params, salt, and wrapped DEK as base64). garden/encrypt.go: EncryptInit (generate DEK, wrap with passphrase KEK), UnlockDEK (derive KEK, unwrap), encryptBlob/decryptBlob using XChaCha20-Poly1305 with random 24-byte nonces. Modified operations: - Add: optional encrypt flag, stores encrypted blob + plaintext_hash - Checkpoint: detects changes via plaintext_hash, re-encrypts - Restore: decrypts encrypted blobs before writing - Diff: decrypts stored blob before comparing - Status: compares against plaintext_hash for encrypted entries 10 tests covering init, persistence, unlock, add-encrypted, restore round-trip, checkpoint, status, diff, requires-DEK guard.

Kyle Isom	08e24b44e0	Step 7: Remaining commands — remove, verify, list, diff. ... Remove: untrack files, remove manifest entries, save. 2 tests. Verify: check blobs against manifest hashes, report ok/mismatch/missing. 3 tests. List: return all tracked entries, CLI formats by type. 2 tests. Diff: compare stored blob vs current file, simple line diff. 3 tests. Each command in its own file (garden/<cmd>.go) for parallel development. Remove, verify, list implemented by parallel worktree agents; diff manual. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-23 21:55:37 -07:00
