+# ProofFrame Devpost Submission Preview
+
+Mode: `pre_live_preview_ready`
+Safe to share: `true`
+Safe to submit: `false`
+
+## Project
+
+- Name: ProofFrame
+- Tagline: B2-ready provenance desk for GenAI media.
+- Repository: https://github.com/adjcjh777/backblaze-proofframe
+- Demo: https://adjcjh-backblaze-proofframe.hf.space/?judge=1
+- Video: TBD after final B2 and Genblaze proof.
+
+## Copy Blocks
+
+### 30-Second Pitch
+
+ProofFrame is not another image generator. It is a media operations desk that turns each generated asset into a reviewable packet: prompt, provider/model metadata, storage reference, checksum, approval state, risk note, manifest, and exportable evidence.
+
+### Short Description
+
+ProofFrame is a review desk for generated media. The local demo creates a campaign, generates mock variants, approves or rejects assets, exports a manifest, and downloads an evidence ZIP with prompts, provider/model fields, storage references, hashes, and approval status. The final hackathon submission gate is to verify the same flow with Genblaze-backed generation and Backblaze B2-backed storage.
+
+### Backblaze B2 Usage
+
+ProofFrame treats Backblaze B2 as the final durable evidence layer, not as a late file-upload checkbox. The public demo currently runs in local/mock mode, but every asset packet already carries the B2-ready object model: storage backend, storage key, checksum, byte size, prompt, provider/model metadata, approval state, and risk note. The repo includes a dedicated B2 S3-compatible storage adapter, a recorded private B2 bucket setup, and a one-command B2 proof runner that will upload one generated asset and one manifest with environment-only credentials. That live upload remains the final submission gate before any public claim is upgraded to completed B2 storage.
+
+### Genblaze Usage
+
+ProofFrame includes a Genblaze/GMICloud provider adapter built around the official Genblaze Pipeline API. In the public mock demo, deterministic generation keeps the workflow inspectable without secrets; the same manifest fields are reserved for the final provider, model, request/run metadata, prompt, and asset checksum. The final submission gate is a live Genblaze-compatible run that proves the provider path and then carries the resulting asset into the ProofFrame review and storage packet.

+- `genblaze_live_proof`: live Genblaze proof - T021 is doing; final evidence status is missing.
+- `credential_handoff`: Live credential handoff is ready - Credential handoff mode is missing_live_env; missing ids: b2_key_id, b2_application_key, genblaze_api_key.
+- `public_video`: final public video - Storyboard mode is mock_storyboard_ready; public video ready is False.
+- `public_video_check`: public video URL check - Public video check mode is pending_video_url; safe_to_submit is False.
+- `final_recording`: Final recording gate is ready - Demo readiness mode is pre_live_mock_ready; final recording ready is False.
+- `final_secret_scan`: final secret scan task completion - T041A is todo; secret scan mode is clear; secret scan ok is True.
+- `final_submission_audit`: strict final submission audit - T041 is todo; audit mode is pre_submit_audit_blocked; audit ok is False.
+- `devpost_submitted`: Devpost submission receipt - T042 is todo; receipt mode is pending_submission; receipt ok is False.
+
+## Claim Boundary
+
+- Public demo evidence proves only the credential-free local/mock judge flow.
+- Do not claim completed live Backblaze B2 storage until T020 has sanitized live evidence.
+- Do not claim completed live Genblaze generation until T021 has sanitized live evidence.
+- Do not submit this packet as final until safe_to_submit is true.
+
+## Next Actions
+
+- Finalize Devpost fields: Demo video URL.
+- Resolve final blocker: Final Devpost web submission checklist is ready.
+- Resolve final blocker: live Backblaze B2 proof.
+- Resolve final blocker: live Genblaze proof.
+- Resolve final blocker: Live credential handoff is ready.
