Reference generated images / videos by path, not by loading metadata. Brand profile loads once per session.\n\nWraps `scripts/c2pa_sign.py` to add a **C2PA manifest** to any SocialForge-generated marketing asset. The manifest carries:\n\n- Machine-readable provenance trail (brand, generator name, timestamp, prompt, target platform)\n- IPTC digital-source-type vocabulary tag (`TRAINED_ALGORITHMIC_MEDIA` / `COMPOSITE_WITH_TRAINED_ALGORITHMIC_MEDIA` / `HUMAN_EDITS`)\n- schema.org CreativeWork assertion (author = brand organization, dateCreated, publishingPrinciples = target platform)\n\n**Why this matters:** EU AI Act Article 50 applies from **2 August 2026**. Generative-AI marketing content distributed in EU markets must be marked in a machine-readable format using open, interoperable standards — C2PA is the emerging backbone. Penalty: up to **€15 million or 3% global annual turnover**. Additional disclosure obligations apply under NY synthetic-performer law (effective June 2026) and FTC May 2026 endorsement guidance.\n\nThe resulting asset is verifiable at [contentcredentials.org/verify](https://contentcredentials.org/verify) or in any C2PA-aware viewer (Adobe Photoshop, Lightroom, Truepic, Microsoft Copilot, etc.).\n\n### C2PA spec versions relevant to SocialForge (June 2026)\n\n- **Content Credentials 2.3** (released 9 February 2026 — [launch post](https://c2pa.org/the-c2pa-launches-content-credentials-2-3-and-celebrates-5-years-of-impact-across-the-digital-ecosystem/)) added support for **live video** (broadcast/streaming), **plain text documents**, **OGG Vorbis audio**, **large AVI video files**, and **EXIF Original Preservation Images**. Relevant to SocialForge because:\n  - Live video signing matters if you're producing Reels / TikTok / Shorts streaming content alongside the planned monthly batch.\n  - EXIF Original Preservation Image format is the cleanest path for signing product photography that the brand wants to preserve through ad ops cropping.\n- **C2PA Spec 2.4** (April 2026 — [spec.c2pa.org/specifications/specifications/2.4](https://spec.c2pa.org/specifications/specifications/2.4/specs/C2PA_Specification.html)) introduces the **AI Disclosure Assertion (`c2pa.ai-disclosure`)** — machine-readable AI transparency info that the EU AI Act Article 50 deployer pathway will read. When `c2pa_sign.py` is on a C2PA SDK ≥ 0.36 that handles 2.4, include this assertion alongside the existing IPTC + schema.org tags. The combination is what the **EU Code of Practice WG1/WG2** drafts reference as the canonical machine-readable mark.\n- **C2PA Trust List** is now handled via the public C2PA Conformance Program — production signing certificates should come from a Conformance-Program-listed CA.\n\nFor the regulatory context (EU Article 50, the voluntary Code of Practice, the provider-vs-deployer obligations split, and where SocialForge falls), see `references/eu-ai-act-article50.md` in this plugin.\n\n## When SocialForge invokes this automatically\n\nIf a brand profile sets `c2pa_auto_sign: true`, the image and video generation pipelines call this script as a post-generation step before delivering the asset. The signed file replaces the unsigned one — original output path is preserved.\n\nIf the brand profile does NOT set `c2pa_auto_sign: true`, generated assets are unsigned by default. You can sign on demand by invoking this skill explicitly.\n\n## Quick examples\n\n```bash\n# Sign an image generated by Vertex AI for Instagram\n/socialforge:c2pa-sign \\\n    --input assets/q3-launch-hero.png \\\n    --output assets/signed/q3-launch-hero.png \\\n    --brand \"Acme Corp\" \\\n    --generator \"Vertex AI Nano Banana Pro\" \\\n    --ai-claim ai-generated-content \\\n    --platform instagram\n\n# Sign a video generated by Kling for TikTok\n/socialforge:c2pa-sign \\\n    --input campaigns/launch.mp4 \\\n    --output campaigns/signed/launch.mp4 \\\n    --brand \"Acme Corp\" \\\n    --generator \"WaveSpeed Kling v3.0 Pro\" \\\n    --ai-claim ai-generated-content \\\n    --platform tiktok\n\n# Production sign with a real C2PA certificate\n/socialforge:c2pa-sign \\\n    --input assets/q3-launch-hero.png \\\n    --output assets/signed/q3-launch-hero.png \\\n    --brand \"Acme Corp\" \\\n    --generator \"Vertex AI Nano Banana Pro\" \\\n    --ai-claim ai-generated-content \\\n    --platform instagram \\\n    --signing-cert /secure/c2pa-prod-cert.pem \\\n    --signing-key /secure/c2pa-prod-key.pem\n```\n\n## AI claim values (IPTC digital source type)\n\n| Value | When to use |\n|---|---|\n| `ai-generated-content` | Asset fully generated by AI (default for SocialForge image/video output) |\n| `ai-assisted-edits` | Human-created asset with AI editing (e.g. brand-watermarked stock photo + AI background replacement) |\n| `ai-no-substantive-changes` | AI used but no semantic change (e.g. AI upscaling, AI noise reduction) |\n\n## Supported asset formats\n\nImage: `.png` · `.jpg/.jpeg` · `.webp` · `.gif` · `.tiff`\nVideo: `.mp4` · `.mov` · `.webm`\nAudio: `.mp3` · `.wav`\n\n## Signing certificate\n\nProduction C2PA signatures require a certificate from a CAI-recognized signing authority (Adobe, Truepic, Numbers Protocol, Microsoft Azure Confidential Ledger). Pass `--signing-cert` and `--signing-key` for production. If omitted, the script generates a **self-signed 90-day dev certificate** — assets sign successfully but verify as \"signature present, signer not in trust list\" at contentcredentials.org/verify. **Do not ship dev-cert-signed assets to production.**\n\nFor production deployment:\n\n1. Obtain a C2PA-compatible signing certificate from a CAI-recognized authority\n2. Store cert + key securely (not in git; use environment variables or a secret store)\n3. Either pass paths on every invocation OR set `c2pa_signing_cert_path` and `c2pa_signing_key_path` in brand profile so the auto-sign hook picks them up\n\nReference: [opensource.contentauthenticity.org/docs/manifest/signing-manifests/](https://opensource.contentauthenticity.org/docs/manifest/signing-manifests/)\n\n## Python dependencies\n\n- `c2pa-python>=0.32.6` — auto-installed on first run\n- `cryptography` — only required for the dev self-signed cert path; auto-installed if missing\n\nThese are part of SocialForge's full install. The script auto-installs them via `pip install --quiet` on first invocation if not present.\n\n## Output\n\nJSON status report to stdout:\n\n```json\n{\n  \"status\": \"success\",\n  \"input\": \"assets/q3-launch-hero.png\",\n  \"output\": \"assets/signed/q3-launch-hero.png\",\n  \"size_bytes\": 482371,\n  \"brand\": \"Acme Corp\",\n  \"generator\": \"Vertex AI Nano Banana Pro\",\n  \"ai_claim\": \"ai-generated-content\",\n  \"c2pa_digital_source_type\": \"TRAINED_ALGORITHMIC_MEDIA\",\n  \"platform\": \"instagram\",\n  \"created\": \"2026-05-17T10:30:00+00:00\",\n  \"manifest_embedded_and_verified\": true,\n  \"c2pa_active_manifest_id\": \"urn:c2pa:...\",\n  \"using_dev_cert\": false,\n  \"verify_url\": \"https://contentcredentials.org/verify\"\n}\n```\n\n## Interoperability\n\nThis skill is intentionally **self-contained** — signing requires nothing beyond this plugin. Manifests follow the open C2PA spec (same manifest schema, same IPTC vocabulary), so any standards-compliant C2PA tool verifies a SocialForge-signed asset identically, and assets signed elsewhere verify here.\n\n## Related\n\n- `scripts/c2pa_sign.py` — the underlying implementation\n- `scripts/generate_image.py` — calls `c2pa_sign.py` as a post-step when brand profile has `c2pa_auto_sign: true`\n- `scripts/video_postprocess.py` — same auto-sign hook for video output\n- `references/eu-ai-act-article50.md` — regulatory context\n- [C2PA spec v2.0](https://c2pa.org/specifications/specifications/2.0/specs/C2PA_Specification.html)\n- [Content Authenticity Initiative](https://contentauthenticity.org/)\n","tagline":"Embed C2PA provenance manifests in AI-generated assets — the machine-readable AI disclosure EU AI Act Article 50 expects (enforceable since 2 Aug 2026), plus the human-approval record for the Article 50(4) exemption.
