+# ECP-0120: Material Watch Surface
+
+Status: Draft
+
+## Problem statement
+
+The web watch page should feel like a real television/player surface, not a protocol console,
+marketing page, or dark decorative shell. It also needs room for modern watch behaviors: channel
+switching, multiview, scrubbing, clipping, direct tuning, and DVR mode.
+
+## Constraints
+
+- Preserve existing live WebTransport playback, DVR replay, public station scanning, share links,
+  and manual signal tuning.
+- Keep the first screen content/player-first and operable with obvious controls.
+- Use YouTube as interaction grammar, not as visual branding.
+- Keep the palette bright enough for daytime/living-room use.
+- Do not rely on browser-specific copy.
+
+## Alternatives considered
+
+- Continue the dark broadcast-console skin from ECP-0118. Rejected because it reads too much like
+  a control-room hero image and too little like a daily-use player.
+- Copy YouTube visually. Rejected because every.channel should inherit watch-page mechanics without
+  borrowing YouTube brand language.
+- Use pure flat CSS. Rejected because the desired direction is a tactile television object with
+  material depth.
+
+## Decision
+
+Rebuild the static web watch surface around a large video player, right-side channel rail, lower
+scrubber, clip controls, and multiview tray. Use generated bitmap material assets for live-preview
+tiles and subtle hardware texture, then layer a lighter skeuomorphic system in CSS: warm wood,
+brushed metal, smoked acrylic, cream buttons, and broadcast-monitor geometry.
+
+The design lineage is intentionally loose: Braun/Ulm clarity for simple control layout, Sony-style
+broadcast monitor seriousness for the player frame, and Bang & Olufsen-style furniture warmth for
+the room/object feel. These references are constraints, not objects to copy.

+## Rollout / teardown plan

+Ship as a static web UI change and validate with desktop/mobile screenshots plus the web build.
+Teardown is reverting the HTML/CSS shell to the previous watch page while leaving playback,

+# ECP-0121: Greedy Multi-Relay Streams
+
+Status: Draft
+
+## Problem statement
+
+Live streams should be publishable to more than one relay at once so viewers can pick the fastest
+path and regional relays can mirror each other. The current public directory shape only exposes one
+`relay_url` per stream, which encourages duplicate publishers when we want redundancy. For OTA
+sources, duplicate publishers are dangerous because each one opens another tuner read.
+
+## Constraints
+
+- Preserve the existing `relay_url`, `broadcast_name`, and `track_name` fields for deployed web,
+  archive, and manual watch links.
+- Keep those primary fields as the compatibility contract; `relays[]` is additive and optional for
+  consumers.
+- Do not duplicate HDHomeRun source reads to get multi-region relay presence.
+- Let the public directory advertise multiple relays before every consumer implements racing.
+- Keep rollback simple: clients can ignore `relays[]` and keep using the primary legacy fields.
+
+## Decision
+
+Add an ordered `relays[]` candidate list to public stream entries and stream upserts. Stream upserts
+continue to require the primary legacy fields; the first relay is mirrored into those fields and
+remains the primary/default path. `control-bridge-web` now forwards all relay transports already
+present in a control announcement instead of flattening to the first relay only. Current consumers
+can keep reading the legacy fields until they explicitly add relay racing.
+
+The intended next step is a single ingest/fanout publisher: read the source once, encode/fragment
+once, publish the same stream objects to LAX and NYC relay sessions, and optionally let relays mirror
+to each other. Consumers can then race candidates greedily by availability/latency without causing
+extra source reads.
+
+## Alternatives considered
+
+- Start one publisher per relay. Rejected because it duplicates source reads and can exhaust physical
+  tuners, which was the LA outage failure mode.
+- Replace the legacy fields with `relays[]`. Rejected because deployed clients and archive workers
+  already depend on the single-relay shape.
+- Accept `relays[]` without primary legacy fields. Rejected because that would make rollback depend
+  on every publisher being downgraded at the same time as the directory.
+- Wait for full relay racing before changing the directory. Rejected because exposing the ordered
+  candidate set is a small compatible step that unblocks incremental consumers.
+
+## Rollout / teardown plan
+
+Deploy the compatible schema first. Then add publisher fanout and consumer relay racing behind
+separate flags. Teardown is removing `relays[]` from upserts and consumers; legacy primary-field
+behavior remains intact throughout.

+# ECP-0122: Publisher Source Locks And Cgroup Cleanup
+
+Status: Draft
+
+## Problem statement
+
+LA channels disappeared when stale proof/archive publisher helpers kept HDHomeRun tuner HTTP streams
+open after the managed publishers restarted. The restarted publishers saw `503 Service Unavailable`
+from the tuners, stopped refreshing the public stream directory, and the guide expired to empty.
+
+## Constraints
+
+- A publisher restart must not leave child media processes holding tuners.
+- A duplicate publisher on the same node must not open the same physical source URL.
+- Keep rollback simple and deployment-owned; no source-device firmware or manual tuner reset should be
+  required for normal recovery.
+
+## Decision
+
+The NixOS publisher wrapper now takes a non-blocking per-source lock under
+`/run/every-channel/source-locks` before launching `ec-node`. If another managed publisher on the
+same node is already reading that input URL, the duplicate launch logs and skips instead of opening a
+second tuner stream.
+
+Publisher and archive worker services also set explicit `KillMode=control-group`,
+`TimeoutStopSec=10s`, and `SendSIGKILL=true`, and archive auto-workers terminate tracked children on
+shutdown before systemd's cgroup cleanup runs. The async `wt-publish` and `nbc-wt-publish` ffmpeg
+children are marked kill-on-drop so cancelled Rust futures do not strand encoder children.
+
+## Alternatives considered
+
+- Rely on operator cleanup only. Rejected because the failure silently empties the public guide after
+  TTL expiry.
+- Run duplicate publishers for redundancy. Rejected because OTA tuner capacity is the scarce resource;
+  redundancy should happen after one source read, via publisher fanout and relay mirroring.
+- Add only systemd cgroup cleanup. Rejected because it does not prevent two managed units from
+  intentionally opening the same source at the same time.
+
+## Rollout / teardown plan
+
+Deploy the NixOS module update to every publisher node. Confirm no stale proof/archive helpers remain,
+all managed publisher units are active, and `/api/public-streams` lists the expected channels.
+Rollback is reverting this module change and redeploying; source locks are runtime files under `/run`
+and disappear on reboot.
