+# Copilot instructions for `distributed-files`
+
+## Build, test, and lint commands
+
+Use npm scripts from `package.json`:
+
+- Install dependencies: `npm ci`
+- Build TypeScript: `npm run build`
+- Run full test suite: `npm test` (runs `vitest run`)
+- Run a single test file: `npm test -- tests/status.test.ts`
+- Run a single test by name: `npm test -- -t "determineState (glob patterns)"`
+
+Linting:
+
+- `npm run lint` — check for lint/format issues
+- `npm run lint:fix` — auto-fix lint/format issues
+- `npm run format` — format code
+
+## High-level architecture
+
+`dfiles` is a manifest-driven CLI that pulls selected paths from remote Git repos into local destinations.
+
+- **CLI entrypoint (`src/index.ts`)** wires Commander commands (`init`, `add`, `pull`, `status`, `list`, `remove`) to command modules and centralizes top-level error handling.
+- **Manifest system (`src/config.ts`, `src/types.ts`)** defines and validates `dfiles.json` (`version: 1`, `entries[]`). Commands (except `init`) call `requireManifest()`, which discovers the manifest by walking up parent directories.
+- **Cache/update layer (`src/cache.ts`)** keeps repo mirrors in `~/.dfiles/cache/<repo-hash>`, where hash is SHA-256 of repo URL (first 16 chars). It uses shallow clone/fetch and recovery paths for stale locks, non-fast-forward pulls, and corrupted caches.
+- **Sync layer (`src/sync.ts`)** copies file, directory, or glob sources from cache to destination. File copies are hash-based (`sha256`) so unchanged files are skipped.
+- **Pull workflow (`src/commands/pull.ts`)** selects entries, groups by `repo#branch`, updates cache once per group, syncs each entry, then prints a summary and exits non-zero if any entry failed.
+- **Status workflow (`src/commands/status.ts`)** is offline-only: it compares current local destinations against cached repo content (including directory hashing and glob-aware comparisons) and reports `current`, `outdated`, or `missing`.
+
+## Key repository conventions
+
+- **Always normalize destination paths with `resolvePath()`** (`src/config.ts`) so `~` expansion and absolute resolution stay consistent.
+- **`source` supports file, directory, and glob semantics**; glob sync/status logic is shared via `isGlobPattern()` + `globBase()` (`src/sync.ts`) and treats glob matches as files with preserved relative structure.
+- **Manifest writes use `saveManifest()`** (pretty JSON, 2-space indent) rather than ad hoc file writes.
+- **Error model is command-level throw + top-level handling**: command modules usually throw `Error`, and `src/index.ts` converts failures into `Error: ...` plus exit code 1.
+- **`pull` behavior is intentionally partial-failure tolerant**: failures are tracked per entry, printed in summary rows, and only then converted to process failure if any errors occurred.
+- **Tests use Vitest with focused module mocks** (notably `simple-git` and cache functions), and test files are organized by subsystem under `tests/`.
+
+## Must follow workflow
+
+1. Always when implementing a feature or bug fix  always create new tests and update exisiting ones as needed. Tests should cover both typical and edge cases.
+2. Always make sure documentation is up to date, including README.md and any relevant comments in the code.
