FIDO2Device interface abstracts hardware interaction (Register, Derive, Available, MatchesCredential). Real libfido2 implementation deferred; mock device used for full test coverage. AddFIDO2Slot: registers FIDO2 credential, derives KEK via HMAC-secret, wraps DEK, adds fido2/<label> slot to manifest. UnlockDEK: tries all fido2/* slots first (checks credential_id against connected device), falls back to passphrase. User never specifies which method. 6 tests: add slot, reject duplicate, unlock via FIDO2, fallback to passphrase when device unavailable, slot persistence, encrypted round-trip unlocked via FIDO2.

# PROGRESS.md
|
||
|
||
Tracks implementation status. See PROJECT_PLAN.md for the full plan and
|
||
ARCHITECTURE.md for design details.
|
||
|
||
**If you are picking this up mid-implementation, read this file first.**
|
||
|
||
## Current Status
|
||
|
||
**Phase:** Phase 3 in progress. Steps 17–18 complete, ready for Step 19.
|
||
|
||
**Last updated:** 2026-03-24
|
||
|
||
## Completed Steps
|
||
|
||
- **Step 1: Project Scaffolding** — removed old C++ files and `.trunk/` config,
|
||
initialized Go module, added cobra + yaml.v3 deps, created package dirs,
|
||
set up cobra root command with `--repo` flag.
|
||
- **Step 2: Manifest Package** — `Manifest` and `Entry` structs with YAML tags,
|
||
`New()`, `Load(path)`, and `Save(path)` with atomic write. 5 tests.
|
||
- **Step 3: Store Package** — content-addressable blob store with SHA-256 keying.
|
||
`New()`, `Write()`, `Read()`, `Exists()`, `Delete()` with atomic writes,
|
||
hash validation, and two-level directory layout. 11 tests.
|
||
- **Step 4: Garden Core — Init and Add** — `Garden` struct tying manifest +
|
||
store, `Init()`, `Open()`, `Add()` handling files/dirs/symlinks, `HashFile()`,
|
||
tilde path conversion, CLI `init` and `add` commands. 8 tests.
|
||
- **Step 5: Checkpoint and Status** — `Checkpoint()` re-hashes all tracked files,
|
||
stores changed blobs, updates timestamps. `Status()` reports ok/modified/missing
|
||
per entry. CLI `checkpoint` (with `-m` flag) and `status` commands. 4 tests.
|
||
- **Step 6: Restore** — `Restore()` with selective paths, force mode, confirm
|
||
callback, timestamp-based auto-restore, parent dir creation, symlink support,
|
||
file permission restoration. CLI `restore` with `--force` flag. 6 tests.
|
||
- **Step 7: Remaining Commands** — Remove (2 tests), Verify (3 tests), List
|
||
(2 tests), Diff (3 tests). Each in its own file to enable parallel
|
||
development. All CLI commands wired up.
|
||
- **Step 8: Polish** — golangci-lint config, all lint issues fixed, clockwork
|
||
clock abstraction injected into Garden, e2e lifecycle test, docs updated.
|
||
|
||
## In Progress
|
||
|
||
(none)
|
||
|
||
## Up Next
|
||
|
||
Step 19: Encryption CLI + Slot Management.
|
||
|
||
## Known Issues / Decisions Deferred
|
||
|
||
- **Manifest signing**: deferred — trust model (which key signs, how do
|
||
pulling clients verify) needs design.
|
||
- **DEK rotation**: `sgard encrypt rotate-dek` (re-encrypt all blobs)
|
||
deferred to future work.
|
||
- **FIDO2 testing**: hardware-dependent, may need mocks or CI skip.
