### GNU General Public License v3.0 (`edge-tts`)

`edge-tts` is licensed under the GNU General Public License v3.0 (GPL-3.0).
`clip-storyboard-director` invokes `edge-tts` strictly as an optional external utility /
library subprocess for audio speech synthesis. The core orchestrator is licensed under MIT,
and users may freely substitute or swap speech synthesis backends without modifying the core.

### GNU Lesser General Public License v2.1+ (`FFmpeg` / `FFprobe`)

FFmpeg is licensed under the LGPL v2.1+ (or GPL v2.0+ depending on build flags).
`clip-storyboard-director` executes FFmpeg strictly via standard unprivileged system
subprocesses (`subprocess.run`) across standard OS PATHs without linking FFmpeg C/C++ libraries.

## Compliance, Level 1 SBOM & Invariant Cross-Reference Matrix

The table below cross-references all 10 project governance invariants (`INV-LOCAL-01` to `INV-SLA-10`) against third-party dependency boundaries and verification mechanisms:

| Invariant ID | Canonical Title | Level 1 SBOM Verification & Architectural Boundary | Status |
| :--- | :--- | :--- | :---: |
| **INV-LOCAL-01** | 100% Local-First & Zero-Egress | Zero external network telemetry; no cloud tracking, phone-home metrics, or external asset transmission. | Verified |
| **INV-UNPRIV-02** | Non-Elevation / `RunAsInvoker` | Runs exclusively in standard unprivileged user-space; zero administrative elevation or root requirements. | Certified |
| **INV-LOOPBACK-03** | Loopback IPC Socket Isolation | All HTTP/WS communication (`board_server.py`, CDP) is hard-bound strictly to `127.0.0.1`. | Verified |
| **INV-SANDBOX-04** | Subprocess Sandboxing | FFmpeg/FFprobe and edge-tts execute in isolated subprocesses with parameterized arguments; zero shell injections. | Verified |
| **INV-CONTINUITY-05** | 4D Persistence Continuity | Bounded character, location, object, and prop tracking stored exclusively in local `project.yaml`. | Verified |
| **INV-CLUEFRAME-06** | Clue-Frame Optical Chaining | Deterministic tail-frame extraction seeds subsequent shot prompts locally via filesystem artifacts. | Verified |
| **INV-STANDALONE-07** | Standalone Production Guarantee | Fully functional media generation and assembly pipeline without hard dependency on external suites. | Verified |
| **INV-MULTIOS-08** | Multi-OS Cross-Platform Parity | Validated deterministic execution across Windows, Linux, and macOS platforms. | Verified |
| **INV-SYNC-09** | Cloud-Sync & Mutex Resilience | Ignores ephemeral sync conflict artifacts (`*-conflict-*`, `*.sync-temp-*`) and honors canonical `LOCK*.txt`. | Verified |
| **INV-SLA-10** | Dual Security SLA Commitment | Formal 48h initial response and 5-business-day triage SLA backed by dedicated security channels. | Committed |

## RunAsInvoker Non-Elevation Certification

`clip-storyboard-director` is certified to run with standard, unprivileged user credentials under Windows, Linux, and macOS. The application does not write to system-wide protected directories, does not install system services, and does not require administrator or root elevation (`RunAsInvoker`).
