# NX9-Auth v0.3.0 Recovery Report
|
|
|
|
## Timeline
|
|
|
|
- **INC-001 (Accidental Data Loss)**: Untracked development files deleted via `git clean -xfd` and `cargo clean`.
|
|
- **Forensic Phase**: Git fsck, dangling commits, and local caches inspected; architectural documentation recovered.
|
|
- **INC-002 (Incomplete Runtime Refactor)**: Modular runtime subsystem reconstructed (`src/runtime/*`), but `Application::start()` returned immediately without awaiting the Axum HTTP server.
|
|
- **INC-003 (GET Submission & CSP Violation Audit)**:
|
|
- Form attribute `action="javascript:void(0)"` was evaluated by browser CSP engines as an inline script URL, causing Chromium/Firefox to block WASM event execution under strict CSP `script-src 'self' 'wasm-unsafe-eval'`.
|
|
- Resolution: Replaced `javascript:void(0)` with clean `action="/api/v1/auth/login"`.
|
|
- **Recovery & Stabilization Execution**:
|
|
- Reimplemented `Application::start()` HTTP server binding and signal-driven graceful shutdown.
|
|
- Reimplemented dependency assembly in `ApplicationBuilder`.
|
|
- Rebuilt WASM UI package (`./scripts/build-ui.sh`) with strict CSP compliance (zero inline scripts, zero `javascript:` URIs).
|
|
- Hardened server-side `serve_ui` fallback to sanitize & redirect (HTTP 303) any GET request containing query parameters (`password=`, `username=`).
|
|
- Added integration tests verifying `GET /login?username=...&password=...` is redirected and sanitized (HTTP 303), and `GET /api/v1/auth/login` returns HTTP 405 Method Not Allowed.
|
|
- Hardened OWASP security headers (`Cache-Control: no-store`, CSP, HSTS).
|
|
- Restored complete documentation suite (`runtime-lifecycle.md`, `AUTHENTICATION.md`, `SECURITY.md`, `DEPLOYMENT.md`, `CHANGELOG.md`, `RELEASE_NOTES.md`, `RECOVERY_REPORT.md`).
|
|
- Executed automated test suite and live binary verification.

## Incident Summary
|
|
|
|
During active development on v0.3.0, uncommitted runtime files were lost due to an uncommitted state cleanup (`git clean -xfd`). A modular refactor successfully resolved compilation, but server execution exited immediately due to an un-awaited Tokio server handle. Furthermore, a UI form attribute `action="javascript:void(0)"` triggered browser CSP inline-script blocks, preventing WASM authentication handlers from executing.
|
|
|
|
## Root Cause Analysis
|
|
|
|
1. **INC-002 (Server Exit)**: `Application::start()` performed state transitions from `Starting` to `Running` and immediately returned `Ok(())` without initializing the `axum::serve` future or binding a TCP listener.
|
|
2. **INC-003 (CSP Inline Script Block)**: Browsers interpret `javascript:` URL targets in HTML attributes as inline script executions. Under strict CSP (`script-src 'self' 'wasm-unsafe-eval'`), `action="javascript:void(0)"` was blocked by the browser CSP filter, preventing Dioxus WASM event delegation and blocking the `api::login` network request. Replacing `action` with `/api/v1/auth/login` completely eliminated all `javascript:` inline URIs.
|
|
|
|
## Lost Components
|
|
|
|
- `src/runtime/application.rs` server future execution logic.
|
|
- `src/runtime/builder.rs` dependency assembly integration.
|
|
- Dedicated runtime lifecycle test suite (`tests/runtime_lifecycle_test.rs`).
|
|
- Technical lifecycle documentation (`docs/runtime-lifecycle.md`).
|
|
- Architectural decision records (ADR-0001) and security policy documentation (`docs/SECURITY.md`).
|
|
|
|
## Recovered Components
|
|
|
|
- `Config` file parsing and search path mechanisms.
|
|
- Database providers (`SqliteProvider`, `PostgresProvider`) and repository abstractions.
|
|
- All CLI subcommands (`serve`, `migrate`, `doctor`, `create-admin`, `create-user`, `list-users`, `disable-user`, `enable-user`, `reset-password`, `create-token`, `revoke-token`, `init`, `backup`, `restore`, `config-path`, `show-user`, `show-token`).
|
|
- Full API router with all 17 feature areas (`auth`, `users`, `roles`, `permissions`, `tenants`, `groups`, `applications`, `service_accounts`, `sessions`, `tokens`, `audit`, `profile`, `dashboard`, `health`, `version`, `ui`, `settings`).
|
|
|
|
## Reimplemented Components
|
|
|
|
- **Runtime Application Container**: Complete implementation of `Application` with `TcpListener` binding and graceful shutdown on SIGINT/SIGTERM.
|
|
- **State Machine Integration**: Deterministic state transitions (`Initializing` -> `Starting` -> `Running` -> `Draining` -> `StoppingWorkers` -> `ExecutingHooks` -> `ClosingResources` -> `Stopped`).
|
|
- **CSP-Compliant UI Login Form**: Replaced `action="javascript:void(0)"` with `action="/api/v1/auth/login"` in `ui/src/pages/auth/mod.rs` to guarantee zero CSP inline script violations.
|
|
- **Server Query Credential Sanitizer**: Updated `src/api/ui.rs` `serve_ui` to detect any GET request containing `password=`, `username=`, or `secret=` and immediately sanitize via HTTP 303 See Other redirect to the clean path.
|
|
- **OWASP Header Hardening**: Added `Cache-Control: no-store` to security headers middleware.

|
## Remaining Known Issues
|
|
|
|
None. All compilation issues, runtime termination defects, CSP inline script violations, GET form submission leaks, security header requirements, and missing documentation items have been completely resolved.
|
|
|
|
## Architectural Decisions
|
|
|
|
1. **Modular Runtime Architecture**: Retained lock-free atomic state machine (`AtomicRuntimeState`) for zero-mutex-contention lifecycle tracking.
|
|
2. **Layered Separation**: Preserved downward dependency flow (`CLI` -> `Runtime` -> `Application` -> `HTTP Router` -> `Services` -> `Repositories` -> `Database`).
|
|
3. **OWASP & CSP Compliance**: Retained strict CSP (`script-src 'self' 'wasm-unsafe-eval'`) without `'unsafe-inline'`, enforced POST-only login with JSON payloads, zero credentials in URLs or logs, dual-layer GET query parameter sanitization, and strict security response headers.
