archipelago 03a4ee1b30 feat(container): manifest-declared generated secrets + companion/quadlet hardening
Generated-secrets system: apps declare `generated_secrets` in their manifest
(kinds hex16/hex32/bcrypt); `container::secrets::ensure_generated_secrets`
materialises them 0600/rootless in resolve_dynamic_env — idempotent and
self-healing (recovers wrongly root-owned secrets with no privilege). Replaces
per-app Rust (deletes ensure_fmcd_password). fedimint-clientd/gateway manifests
now declare fmcd-password / fedimint-gateway-hash.

companion.rs: rebuild the auto-built :latest image when its build context changes
(staleness check) so baked-in fixes (e.g. guardian-UI CSS) actually reach nodes.

quadlet.rs: skip PublishPort under Network=host (podman rejects the combo, exit
125) + regression tests.

UI: "Fedimint Guardian" rename, fedimint-clientd/nostr-rs-relay/meshtastic tagged
as Services (headless backends), gateway icon fallback.

Deployed + verified on .228 (generated-secrets fixed fedimint-gateway start;
grafana/strfry orphan crash-loop units removed).

name: Fedimint Client
version: 0.8.0
description: Fedimint ecash client daemon (fmcd). Lets the node hold Fedimint ecash and join federations; the wallet talks to it over a local REST API.
container:
# fmcd built from source (github.com/minmoto/fmcd v0.8.0, fedimint-client
# 0.8.2 — iroh-capable). No usable upstream image exists, so we build + push
# this to the node registry. Pin the tag to match the REST shapes coded in
# core/archipelago/src/wallet/fedimint_client.rs (validated against 0.8.2).

# No entrypoint override: the image's resilient `fmcd-run` launcher loops
# fmcd and retries on join failure (fmcd needs >=1 federation to boot), so an
# unreachable default never crash-loops. All config comes from FMCD_* env
# below. Nodes can join more federations via wallet.fedimint-join.
# Auto-generated on first install (random hex, 0600, rootless-owned) so the
# app needs no host provisioning. The wallet bridge reads the same file.

# NOTE: this is a CLIENT, not the guardian — it does not require the local
# `fedimint` app. It joins external federations (default below), so it can be
# bundled standalone on every node.

security:
# fmcd's `fmcd-run` launcher chowns its /data (existing federation DB) on
# every start. With the default `cap_drop: ALL` and no caps added back, that
# chown fails and fmcd dies "Operation not permitted (os error 1)" — but ONLY
# once /data holds a joined federation (a fresh/empty dir needs no chown, so
# it appeared to work). Restore the standard container capability set so the
# startup chown succeeds (#7). Verified by bisection on .116: these caps make
# fmcd boot + serve /v2/*; DAC_OVERRIDE or SETUID/SETGID alone do NOT.

# NOT isolated: fmcd needs outbound UDP + Mainline DHT (port 6881) + iroh
# relays to reach iroh-transport federations. `bridge` gives NAT'd outbound
# (UDP/DHT/iroh hole-punch all work) plus the published 8178→8080 port the
# wallet bridge targets. ("open" is not a valid policy — it made the loader
# skip this whole manifest, so fmcd never ran and federations never joined.)
# Lock down once the default federation's reachability model is finalized.

# join reliability from a real second node before relying on auto-bundle.

# fmcd serves only authenticated /v2/* routes — there is no unauthenticated
# /health endpoint, so an http probe to /health 404s forever and pins the
# container in "(starting)". fmcd's own image also ships neither curl nor wget.
# Use a TCP probe: the Quadlet renderer skips it (no HealthCmd emitted) and the
# host-side lifecycle layer verifies reachability, so the container reports
# "running" instead of a perpetual false-negative "(starting)".
