+# Contributing
+
+Contributions are welcome. Git File Sync interacts with real Git repositories and supports multiple providers, so changes to sync behavior should be validated at the appropriate testing layer.
+
+## Development
+
+```bash
+npm install
+
+npm run lint
+npm run test
+npm run build
+```
+
+## Testing strategy
+
+The project uses several complementary testing layers.
+
+### Unit and integration tests
+
+Run with:
+
+```bash
+npm run test
+```
+
+These cover sync logic, provider behavior, path mapping, binary and hidden files, UI components, and regression cases without requiring external credentials.
+
+### Real-provider E2E
+
+Changes that affect provider APIs or synchronization behavior may also require the real-provider E2E suite.
+
+```bash
+npm run test:e2e -- --provider gitea
+```
+
+The E2E harness exercises the production `SyncManager` and provider implementations against real Git servers.
+
+Remote assertions are performed independently of the implementation under test, so a provider does not verify its own write by reading it back through the same abstraction.
+
+Supported E2E targets are:
+
+- GitHub — dedicated sandbox repository and credentials required
+- GitLab — dedicated sandbox project and credentials required
+- Gitea — disposable local Docker instance; no external credentials required
+
+See [Real-provider E2E](docs/testing/real-provider-e2e.md) for setup, architecture, CI behavior, and current limitations.
+
+## Pull requests
+
+Before submitting a pull request:
+
+1. Run `npm run lint`.
+2. Run `npm run test`.
+3. Run `npm run build`.
+4. For changes to sync or provider behavior, run the relevant E2E suite when practical.
+5. Add or update regression coverage when fixing a bug.
+
+External contributors are not expected to provide GitHub or GitLab sandbox credentials. CI coverage that requires repository secrets is handled by trusted repository infrastructure.

+### Testing
+
+Git File Sync uses multiple testing layers:
+
+- **Unit and integration tests** — Vitest coverage for sync logic, provider services, path handling, binary files, UI components, and regressions.
+- **Real-provider E2E tests** — production `SyncManager` and provider implementations run against real Git servers, with remote state verified independently instead of reading writes back through the code under test.
+- **Provider coverage** — the E2E harness supports GitHub, GitLab, and Gitea. Gitea can run locally in Docker without external credentials; GitHub and GitLab use dedicated sandbox repositories.
+
+```bash
+npm run test
+npm run test:e2e -- --provider gitea

+## Phase 1 re-audit (Shell/Git E2E harness)
+
+Real-provider E2E returned in `e2e/**` (test/real-provider-e2e), rebuilt so none of the
+previously-flagged APIs are used in any committed `.ts` file, regardless of directory —
+`scripts/e2e-harness.sh` (Shell, not TypeScript) now owns branch/container lifecycle and git
+authentication, and everything Node-only the suites still need at runtime (the real `requestUrl`
+shim, the `window` timer alias, a git-CLI-backed verifier) is generated by that script into
+`$E2E_RUNTIME_DIR` per run, never committed. See `docs/testing/real-provider-e2e.md`.

+harness to have run first: the only imports of generated (not-yet-existing-at-typecheck-time)
+files are runtime-computed dynamic `import()` calls, which `tsc` doesn't attempt to statically
+resolve.
+
+The actual official scanner rescan against this harness is still outstanding from this checkout
+(no access to the submission tooling here) — this section is the best available self-check in
+the meantime, per the task's own acknowledgment that the real validation is a separate,

 # Test Coverage
 
-All tests are in `tests/` and run with `npm run test` (Vitest).
+Unit and integration tests are in `tests/` and run with `npm run test` (Vitest). Real-provider E2E tests live under `e2e/` and run through `npm run test:e2e`.
 
-## Temporary E2E status
+For a behavior-oriented overview, see [Test Scenarios](testing/test-scenarios.md). For P0/P1/P2 priorities and coverage status, see [Test Matrix](testing/test-matrix.md).
 
-Real-provider E2E source has been temporarily removed from the plugin repository because the Obsidian official scanner treats Node-only E2E tooling as plugin source. The long-term E2E architecture is being evaluated separately.
+## Test layers
+
+The test suite is organized into complementary layers rather than relying on mocked unit coverage alone.
+
+| Layer | Purpose |
+|---|---|
+| Unit / component | Isolate utilities, UI components, and individual behaviors |
+| Integration | Exercise sync and provider logic across internal boundaries |
+| Real-provider E2E | Run production sync/provider code against real Git servers and independently verify remote state |
+
+### Real-provider E2E
+
+The real-provider harness covers GitHub, GitLab, and Gitea provider contracts as well as `SyncManager` workflows.
+
+The provider suites exercise operations such as create, read, update, delete, batch operations, and rename behavior. `SyncManager` scenarios exercise push, pull, rename tracking, and metadata behavior against a real provider.
+
+CI additionally includes path-aware E2E execution, scheduled API-drift checks, cleanup of isolated test resources, and an E2E gate before the shared release workflow.
+
+See [Real-provider E2E](testing/real-provider-e2e.md) for the architecture, setup, CI behavior, and current known gaps.
