Phase 2 of the teaching demo: everything the status page will need is now
reachable over HTTP.
- New crate crates/web (axum). JSON endpoints for status, peers, local
routes (announce / withdraw), received routes, the exact UPDATE bytes a
local route produces per session, and well-known community names.
Communities are accepted as ASN:VALUE or by name (NO_EXPORT, BLACKHOLE,
...); large communities as A:B:C. Policy errors map to 403/409/422.
- GET /api/events is a server-sent event stream merging session up/down,
local route and Adj-RIB-In changes, with lag notifications.
- GET /metricz serves Prometheus metrics; the server crate now counts
messages sent/received by type and sessions established.
- The runnable main moves from crates/server to bin/bgp so it can depend
on both server and web without a cycle. `cargo run -- config.textpb`.
- Config gains http_endpoint; unset disables the API.
- Integration tests drive the API against a live server with a real BGP
peer, including verifying the wire view matches the bytes the peer got.

- Implement passive-side BGP FSM (OpenSent → OpenConfirm → Established)
with hold timer, keepalive timer, and NOTIFICATION on expiry
- Add bgp-server crate: config validation, TCP listener accept loop
(BgpServerBuilder → BgpServer), connection dispatch
- Add bgp-rib crate: Adj-RIB-In actor owning route state with event
broadcast for streaming consumers and snapshot for introspection
- Wire Adj-RIB-In into FSM: announce/withdraw on UPDATE for both legacy
IPv4 NLRI fields and MP_REACH/MP_UNREACH path attributes
- Add bgp-integration-tests crate with 15 end-to-end tests covering
session establishment, timers, UPDATE handling, and RIB introspection
- Fix require_empty! macro bug in open.rs (checked wrong buffer)
- Fix FourByteAsn capability parser returning consumed buffer as remainder
- Fix tracing subscriber not being installed in TracingArgs::install
- Expand docs/RFCs.md with full implementation status across 15 RFCs
