Submission Evidence Package
This file is the internal source of truth for Devpost submission assets. Anything marked "public-ready" can be copied into Devpost or the public README. Anything marked "final gate" must not be claimed as completed until the linked task is done.

Judge Quickstart
- Open https://adjcjh-backblaze-proofframe.hf.space/?judge=1.
- Confirm the first screen shows the Sponsor Evidence Model and the fail-closed final gate.
- Use Judge Demo to create a local/mock media packet.
- Inspect the asset ledger, manifest preview, approval state, checksum, and downloadable evidence ZIP.
- Read
docs/assets/judge-brief.md,docs/assets/judge-crosswalk.md,docs/assets/judge-evidence-index.md, anddocs/assets/final-submission-control.mdfor the safe claim boundary: B2 and Genblaze code paths are implemented, while live proof remains final-gated.

Safe Devpost Draft
Project name: ProofFrame
Tagline:
B2-ready provenance desk for GenAI media.
One-liner:
ProofFrame turns generated media into approved evidence packets with B2-ready manifests, Genblaze-gated provider metadata, checksums, review status, and an exportable proof bundle.
Short description, safe before final live integrations:
ProofFrame turns generated media into reviewable asset packets. The current app lets a team create a campaign, generate variants in local demo mode, approve or reject assets, and export a manifest with prompts, provider/model fields, storage references, checksums, and review status. The final hackathon submission gate is to verify the same flow with Genblaze-backed generation and Backblaze B2-backed storage.
Short description, safe after T020 and T021:
ProofFrame turns Genblaze-generated media into Backblaze B2-backed asset packets. Each packet includes prompt history, provider/model metadata, storage references, checksums, approval state, and an exportable manifest so creative teams can reuse generated media with confidence.
Suggested Devpost Sections
Inspiration
Generated media is easy to create but hard to govern. Teams often lose the exact prompt, model, approval status, and storage evidence for the assets they end up using.
What It Does
ProofFrame provides a browser-based review desk for generated media. It creates a campaign, generates candidate assets, lets reviewers approve or reject them, and exports a manifest that ties each asset to its prompt, provider, model, storage backend, object reference, hash, and review status.
How We Built It
FastAPI powers the API and manifest flow. The browser UI is a single-file index.html proof ledger. Storage is abstracted behind local and Backblaze B2-compatible backends. Generation is abstracted behind local mock and Genblaze-backed provider paths.
Challenges
The main challenge is keeping public claims aligned with verified sponsor integrations. ProofFrame is built with fail-closed adapters so missing B2 or Genblaze configuration is visible instead of silently falling back.
What Is Next
Add team roles, signed judge access links, richer asset types, and a release dashboard for retiring or reproducing approved media packets.
Evidence Hygiene
- Never upload
.env, credentials, cookies, browser session files, or raw signed URLs. - Do not include private Backblaze bucket names or account ids in public screenshots unless they are dedicated demo resources.
- Prefer sanitized object references plus checksums in screenshots and manifests.
- Keep public copy aligned with
docs/public_claim_freeze.md.
