# ECP-0031: HDHomeRun End-to-End Test (Single Host, Two Nodes)

Status: Draft

## Problem

We need a real end-to-end test that exercises the full ingestion and transport path against a real HDHomeRun on the LAN. Unit tests cover a lot of logic, but they cannot validate:

- live TS ingest from the tuner
- chunking on real packets
- manifest creation/signing
- stream encryption/decryption
- MoQ publish/subscribe over QUIC between two nodes
- subscriber verification and HLS write-out

## Decision

Add an ignored integration test that:

- spawns `ec-node moq-publish hdhr ...` against a user-provided HDHomeRun host and channel
- reads the publisher's printed endpoint addr, broadcast name, and track name
- spawns `ec-node moq-subscribe ... --subscribe-manifests --require-manifest --network-secret ...`
- asserts that the subscriber writes `index.m3u8` and at least one `segment_*` file

The test is opt-in and runs only when environment variables are present:

- `EVERY_CHANNEL_E2E_HDHR_HOST`
- `EVERY_CHANNEL_E2E_HDHR_CHANNEL`

## Details

- Publisher uses `--publish-manifests --epoch-chunks 1 --network-secret <hex>`.
- Subscriber uses `--require-manifest --max-invalid-chunks 0` to enforce verification.
- A new subscriber flag `--stop-after N` allows deterministic termination.

## Consequences

- Local developers can validate true end-to-end behavior before sharing builds.
- CI remains unaffected unless explicitly enabled.
