# every.channel

A global, disaggregated mesh of relays that turns local ATSC antennas into a coherent, worldwide stream. The stack is Rust-first, MoQ-native, and designed for deterministic chunking so identical broadcasts yield identical data.

## Goals

- Free, global access to broadcast TV through user-run relays.
- Deterministic encoding and chunking to make availability a coordination problem.
- Clean layering: capture -> transcode -> MoQ publish -> relay -> client playback.
- Cross-platform clients: Tauri app, CLI, and a static web UI.

## Repository layout

- `crates/ec-core`: shared types and determinism profiles.
- `crates/ec-hdhomerun`: HDHomeRun discovery and lineup scaffolding.
- `crates/ec-linux-iptv`: Linux DVB ingest scaffolding.
- `crates/ec-iroh`: iroh transport scaffolding.
- `crates/ec-crypto`: stream key derivation helpers.
- `crates/ec-eth`: Ethereum-compatible protocol representations and commitments.
- `crates/ec-ts`: MPEG-TS timing and table parsing.
- `crates/ec-chopper`: deterministic ffmpeg chunking scaffolding.
- `crates/ec-moq`: MoQ data model and relay scaffolding.
- `crates/ec-node`: node runner (ingest + publish).
- `crates/ec-cli`: CLI for discovery and node control.
- `apps/tauri`: desktop client shell.
- `apps/tauri/ui`: Dioxus web frontend embedded in the Tauri app.
- `docs/USAGE.md`: runbook for viewer and ingest pipelines.
- `docs/IROH_EXAMPLES.md`: summary of iroh repos/examples used for design.
- `docs/`: architecture, roadmap, and MoQ notes.
- `contracts/`: Solidity contracts for compact private-chain settlement rails.

## WebTransport Watch (MoQ)

Publish (node -> Cloudflare relay):

```sh
cargo run -p ec-node -- wt-publish \
  --url https://relay.every.channel/anon \
  --name la-nbc \
  --input http://<hdhr-host>/auto/v4.1 \
  --control-announce \
  --control-endpoint-addr-out /tmp/la-nbc-control-endpoint.json
```

`wt-publish` defaults to `--passthrough=true` so relay and archive retain exact CMAF fragment bytes.

Watch (web):

```txt
https://every.channel/watch?url=https%3A%2F%2Frelay.every.channel%2Fanon&name=la-nbc
```

Archive (relay -> CAS objects + JSONL manifests):

```sh
cargo run -p ec-node -- wt-archive \
  --url https://relay.every.channel/anon \
  --name la-nbc \
  --output-dir /tank/every-channel/archive \
  --manifest-dir /var/lib/every-channel/manifests
```

Replay server (archive -> HLS DVR endpoints):

```sh
cargo run -p ec-node -- wt-archive-serve \
  --output-dir /tank/every-channel/archive \
  --manifest-dir /var/lib/every-channel/manifests \
  --listen 0.0.0.0:7788
```

Control protocol (iroh gossip, relay + direct transport discovery):

```sh
# Listener (on node A)
cargo run -p ec-node -- control-listen --gossip-peer <node-b-endpoint-addr-json>

# Announcer (on node B)
cargo run -p ec-node -- control-announce \
  --stream-id la-nbc \
  --relay-url https://relay.every.channel/anon \
  --relay-broadcast la-nbc \
  --gossip-peer <node-a-endpoint-addr-json>

# Resolver (consumer picks best announced path)
cargo run -p ec-node -- control-resolve \
  --stream-id la-nbc \
  --prefer direct-first \
  --gossip-peer <node-a-endpoint-addr-json>

# Bridge iroh control announcements to every.channel public web list
EVERY_CHANNEL_WEB_UPSERT_TOKEN=<token> \
cargo run -p ec-node -- control-bridge-web \
  --directory-url https://every.channel \
  --gossip-peer <node-a-endpoint-addr-json>
```

`wt-publish`, `control-announce`, `control-listen`, `control-resolve`, and `control-bridge-web` print both
`control endpoint id` and `control endpoint addr` on startup. Use the `endpoint addr` JSON for
`--gossip-peer` when bootstrapping.

Default discovery identity:

- If you pass `--stream-id`, that exact value is announced.
- If you do not pass `--stream-id`, `ec-node` now prefers a broadcast-scoped ID when the selected
  channel exposes usable broadcast metadata. HDHomeRun sources also probe early TS packets to fill
  missing `tsid` / `program_number`, and raw TS inputs can derive identity directly from PAT data.
- ATSC PSIP parsing now covers `MGT`, `TVCT/CVCT`, `STT`, `RRT`, `EIT`, and `ETT`. `EIT` and `ETT`
  are accepted on the PIDs advertised by `MGT`, not only on the base PSIP PID `0x1FFB`.
- Discovery identity currently consumes `PAT` plus `VCT` data. `RRT`, `EIT`, `ETT`, and full `STT`
  parsing are available for inspection and future policy, but they do not currently change the
  default dedupe key beyond the existing broadcast identity fields.
- PAT-derived promotion is intentionally conservative: only single-program streams are promoted. If
  the probe sees multiple non-zero programs, `ec-node` does not guess and keeps the stream
  source-scoped.
- Sources without usable broadcast metadata still fall back to source-scoped IDs.

Ethereum rails:

- `ec-node` keeps BLAKE3 `manifest_id`s and `merkle+blake3` object proofs on the wire, and also
  emits Ethereum-compatible ABI commitments for settlement.
- Manifests can now carry both local Ed25519 signatures and optional secp256k1 EIP-712 signatures
  over `ManifestBody`. Set `EVERY_CHANNEL_MANIFEST_SIGNING_KEY` for the local signer and
  `EVERY_CHANNEL_ETH_MANIFEST_SIGNING_KEY` for the Ethereum-native signer.
- Stream descriptors and iroh control announcements now carry Keccak commitments so broadcast
  identity, discovery, and manifest settlement share one vocabulary.
- The new `contracts/EveryChannelRail.sol` contract is intentionally storage-light: it stores only
  latest commitment pointers, while full manifests and media stay off-chain on iroh/relays/archive.
- Observation consensus now has dedicated Solidity surfaces:
  `contracts/EveryChannelWitnessRegistry.sol` and
  `contracts/EveryChannelObservationLedger.sol`.
- `scripts/op-stack/anvil-reality-smoke.sh` validates the observation rail against real archive
  data pulled from `ecp-forge`, not only synthetic fixtures.
- `nix/modules/ec-op-stack.nix` and `docs/OP_STACK_ECP_FORGE.md` define the repo-owned OP Stack
  operator path for `ecp-forge`.
- The dev shell now includes `forge`, `cast`, `anvil`, and `solc`, and the repo ships a
  top-level `foundry.toml`.

## Status

This repository is intentionally minimal. It captures the initial architecture and scaffold for a MoQ-first network and will expand as proposals are accepted.
