Kyle Isom 661c050d83 Step 5: Checkpoint and Status.

Checkpoint re-hashes all tracked files, stores changed blobs, and
updates per-file timestamps only when content changes. Missing files
are skipped gracefully. Status compares each tracked entry against
the filesystem and reports ok/modified/missing.

CLI: sgard checkpoint [-m message], sgard status.
4 new tests (changed file, unchanged file, missing file, status).

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: Steps 1–5 complete. Ready for Step 6 (Restore).

Last updated: 2026-03-23

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.

Known Issues / Decisions Deferred

Blob durability: blobs are not stored in git. A strategy for backup or replication is deferred to a future phase.
gRPC remote mode: Phase 2. Package structure is designed to accommodate it (garden core separates logic from CLI wiring).
