Node-scoped demo apps and persistent media
Status: implementation under qualification; not deployed or accepted.
The V4V demo is restricted to Yaya. The global catalog and other nodes must not
receive an install button or banner for this prototype. Its manifest lives in
demos/node-demo-v4v/, deliberately outside public apps/ generation.
Catalog boundary
A node may load node-app-catalog.json beside its normal catalog. This document
must carry a valid pinned release-root signature, schema: 1,
scope: "single-node-demo", the exact target_node_did, and an unexpired
expires_at. Entries use the reserved node-demo- namespace, include validated
image manifests, and cannot replace existing catalog IDs. It is a separate
file; global signed bytes remain intact. No public mirror fetch or peer
redistribution is implemented for this file.
The authenticated /api/node-app-catalog endpoint returns the original signed
bytes only after these checks. The dashboard combines these entries/promotions
for display without saving them into its normal browser fallback catalog.
Removal, invalid signatures, expiry or another node's DID remove that demo
listing. They do not erase installed app data. Installation still uses the
normal app manifest, image, port and lifecycle enforcement.
Current activation: stage the signed file atomically, then restart the backend to reload its manifest overlay. Automatic delivery of private catalog revisions is not claimed. Qualification must test copying the file to a different node, expiry, signature tampering, backend restart and preservation of public entries.
V4V app
Source baseline: private V4V demo-portainer commit
3ae171d6b0c728665a860520fe393c0abb772798. Retain the original demo songs,
attribution and destinations. The demo keeps PULSEWIRE_LN_MODE=mock and its
existing password login. It does not inject Archipelago's native Nostr signer.
The media bridge is a distinct, non-signing integration.
Candidate bridge source: 5bc5f61b. Session and receipt secrets are generated
by the manifest only when missing. For this migration, preserve the existing
password hash and seed it privately as node-demo-v4v-password-hash before
installation. Missing credentials must fail installation; do not fall back to
the upstream shared password. General public first-run credential provisioning
is outside this node-only demo and must be implemented before a public listing.
The login backdrop was captured from the running app's actual canvas in an isolated browser context, with the form hidden. Use this asset for the node-only “Sovereign Music” promotion. The public artifact can include the image; visibility of the app/promotion is controlled by the scoped catalog.
Before migration, back up the existing Portainer data/media volumes and secret configuration privately. Qualify a separate copy first. Do not attach both live containers to the same writable database. Keep the original stack and volumes available for rollback until the managed replacement passes lifecycle checks. No live V4V state or Portainer stack has been changed by this implementation yet.
Persistent player contract
The app declares metadata.launch.media_controls: archipelago-v1. The dashboard
retains its iframe while hidden and controls that same player through messages;
it never copies a protected media URL into a second audio player. The app checks
the exact dashboard origin and parent window; the host checks the exact loaded
app origin/window and a per-session nonce. The protocol carries bounded title,
artist, time, duration and playback state, plus play/pause/seek/next/previous
controls. It contains no credentials, signer operations or payment commands.
The bottom bar is hidden while the app player is open. Closing the app shows the bar while audio continues; Open app reveals the retained session. Closing the bar pauses playback and releases the hidden frame. Starting a Cloud track pauses the app player. Late state from the paused player must not steal playback back. Logout/unmount must release the frame and its state.
Required remaining evidence: actual mounted iframe survives close/reopen, mobile/desktop controls and layout, fresh install and copied-volume upgrade, restart/rollback, native companion background/resume, real catalog audience rejection on another node, and exact final artifact hashes. Unit tests alone are insufficient for this acceptance.
Qualification checkpoint: the dashboard suite passed 1,241 tests in 155 files. The app bridge/player tests passed four tests, including pre-login connection, origin/nonce rejection, locked controls and removal of metadata after relocking. The isolated container reached HTTP health 200, then exposed the management reaper's separate-storage ownership bug. Runtime acceptance is blocked on its tested deployment; the old V4V image and live Portainer volumes are untouched.
Registry qualification — 2026-10-06
The node-only manifest now pins the staged image by immutable digest:
sha256:13044ecbeae9eb17bc98cc531ca202db9e9a0db8dc2ce01bb9f8cb789248d020.
The registry namespace is chaum/v4v-demo, where the publisher has package write
access. This does not publish an app catalog entry.
Anonymous registry access verified the raw manifest digest and raw Docker
configuration blob. Its configuration digest matches the qualified local image,
sha256:cd56bef6ec2c9d5d56b41d370c735fc3b4c12885acb1530be75c79a5dbde923f.
The raw blob retains the Node /healthz probe, 30-second interval, 3-second
timeout, 10-second start period and three retries. skopeo inspect --config
normalizes this configuration and omits the Docker Healthcheck field; therefore
that output alone must not be used to decide whether this image retains it.
The accepted push explicitly used Docker v2 schema 2 format.
This is registry verification, not managed-install acceptance. Root-signed node catalog, copied-data installation, lifecycle checks, physical companion checks and final dashboard cold-launch regression remain required. Deployment writes to dev and Yaya are paused because another session installed a mining candidate on both nodes; reconcile source before replacing either build.
