The shared edge config for rutster-edge (T2 modular) and rutster-allinone
(T1 solo). ~6-line site block + global options per spec §3.2 / TLS brief
§3(a):
* read_body 30s / read_header 30s — Twilio webhook budget (15s cap by
invariant 6 + slack).
* write 0 — 20ms media frames self-flush; never write-timeout.
* idle 24h / stream_close_delay 24h — above max call duration (invariant
3); the universal 60s-class default kills quiet mid-call WS.
* reverse_proxy + header_up — Caddy sets honest X-Forwarded-Proto/Host/For
for the engine's reconstruct_public_url (plan-A Task 5); engine-side
RUTSTER_TRUSTED_PROXIES is the trust gate (fail-closed default).
CI override via RUTSTER_LOCAL_CERTS=true uses Caddy's internal CA (no
ACME in CI per spec §9). The reload-during-live-call smoke (Task 9)
regresses the stream_close_delay mitigation against caddy #6420/#7222.

One Dockerfile, four named --target stages: rutster-engine (FOB),
rutster-brain (brain), rutster-edge (custom xcaddy + curated DNS plugins
cloudflare/route53/porkbun/hetzner/desec, duckdns excluded per spec §3.2),
rutster-allinone (s6-overlay v3 supervising caddy + FOB + brain +
valkey-server).
Builder pins rust:1.85-slim-bookworm (matches rust-toolchain.toml).
libopus-dev in builder, libopus0 in runtime (matches dev — spec §6.1
distro-over-static-bundled). Brain image gets libopus0 too: although the
brain never calls an opus symbol, the linker records NEEDED:libopus.so.0
because rutster-brain-realtime depends on rutster-media (spec ambiguity
resolved in this slice's plan README).
All-in-one vendors s6-overlay v3.2.0.0 (ISC) + uses upstream valkey/valkey
binary (COPY --from pattern, BSD-3). Bundled-binary licenses
aggregation-clean vs GPL-3 (Caddy Apache-2.0). No Rust crates touched;
cargo-deny unaffected.
s6-rc service definitions land in this commit (caddy/engine/brain/
valkey-database run scripts + dependency edges). The Caddyfile lands in
Task 3 (same PR); the image-build CI job (Task 7) runs after both.
