Solution: LP-0017 — Whistleblower: censorship-resistant document upload and indexing

[jefdiesel]

Solution for LP-0017 — Whistleblower (censorship-resistant document upload + indexing on the Logos stack).

• Repo: https://github.com/jefdiesel/whistleblower-lp0017
• Narrated demo video (RISC0_DEV_MODE=0): https://github.com/jefdiesel/whistleblower-lp0017/releases/tag/v0.1.0
• Full writeup, FURPS self-assessment, and per-criterion checklist in solutions/LP-0017.md.

Summary. A reusable upload→broadcast→anchor module (wb-index), a permissionless + idempotent + resumable batch-anchor CLI, and an on-chain LEZ program registry (SPEL) — deployed on a standalone LEZ sequencer with single- and 50-CID batch anchors verified on-chain (real Codex CIDs + canonical SHA-256 metadata hashes), queryable by CID. 30 tests, CI green, dual-licensed MIT OR Apache-2.0.

Open questions for evaluators (also asked in #builder-hub) — these determine a few criteria, so flagging them up front:

1. Deployment target. Does a standalone-sequencer deployment (with the program's RISC0 image id as the documented address) satisfy "deployed and tested on LEZ devnet/testnet", given there's no published public LEZ sequencer/RPC endpoint? (Criterion S2 itself specifies a standalone sequencer for the E2E/CI tests.) If public-testnet settlement is required, is there a public bedrock/indexer endpoint, or is running the full node stack expected?
2. Video "proof generation". The registry uses public state → public execution on the sequencer's executor, so there's no per-transaction STARK proof to display. The video shows RISC0_DEV_MODE=0 + the real public-execution output (executor run + on-chain persistence). Is that sufficient, or do you need a private-proof workload on camera?
3. Live Delivery (Waku) demo. There's no macOS-arm64 Logos Delivery/Waku binary published, so the live Delivery beat uses the tested dev path on the build machine (issue filed). Is a Linux-run Delivery demo acceptable?

The writeup documents these (and a couple of other environment/upstream-blocked items) honestly. Happy to address any follow-ups.

Hi @jefdiesel . Thank you for your submission!

I quickly checked it and there are things you must address before we would proceed:

• Basecamp GUI not built and not packaged;
• deployed to a local sequencer (no public LEZ endpoint);
• video explicitly does not show proof generation (hope I did not misunderstood);

Also, CI on PR must pass before we review it properly.

Thank you again, and please, re-open once you address points above.
