`headroom monitor` becomes a full-screen ratatui TUI by default;
the previous behaviour (line-delimited JSON, useful for scripts and
tests) is preserved behind --json.
5 — Monitor TUI
New `crates/headroom-cli/src/tui.rs` (~700 lines incl. tests).
Main thread does subscribe + initial status() + route_list() before
entering raw mode, so connect errors surface as clean stderr
messages instead of corrupting the terminal. A reader thread owns
the headroom_client::Client and forwards each subscription event
through a crossbeam channel; an input thread blocks on
event::read() and forwards keys (q / Esc / Ctrl-C) through a
second channel; the main thread `select!`s both plus a 10 Hz
ticker (so uptime + staleness display advance even when no
events are flowing). On quit the OS reaps the reader; a CLI tool
doesn't need a graceful UnixStream shutdown.
Layout: outer block carries the profile / version / uptime in the
top-right title and a footer with subscribed topics + an overflow /
error / disconnected banner when relevant. Inside: bus DSP gauges
(AGC target, compressor GR, limiter GR, true peak), a loudness
panel (momentary / short-term / integrated, greyed when stale),
and a streams table with route + Layer A reduction column.
Wire types caught up to the daemon
`headroom-ipc::RoutingEvent` gained `StreamRemoved`,
`LayerAAttached`, `LayerADetached` variants — these are events the
daemon already publishes (registry.rs §pw) but that
weren't typed in the proto. Without `StreamRemoved` the TUI would
accumulate departed streams forever; without the Layer A pair the
per-stream column couldn't track tap state.
New `LayerALevel` struct types the `meters/layer_a_level` payload
(node_id, app, volume_lin, reduction_db).
`headroom_core::agc::LOUDNESS_FLOOR_LUFS` is now `pub` — it's
published as-is in MeterTick.*_lufs fields when ebur128 has no
useful measurement yet, so clients need it to render "no
measurement" without hard-coding `-200.0`.
Toolchain notes
ratatui and crossterm pinned to =0.28.1. Newer ratatui pulls in
`instability` 0.3.12 + `darling` 0.23 which need rustc 1.88+; the
project pins 1.86 via rust-toolchain.toml. Lockfile also pins
`instability` to 0.3.7 and `darling` to 0.20.10 (older patches that
still build on 1.86).
Verified
185 tests passing (was 178: +5 for TUI event mapping +
fmt_uptime, +2 for stream_removed / layer_a_level handling).
Clippy clean at -D warnings --all-targets.
Live smoke: daemon emits routing/{stream_routed, stream_removed,
layer_a_attached, layer_a_detached} and meters/{tick, layer_a_level}
in shapes that round-trip cleanly through the new typed enums.
TUI binary survives raw-mode init + initial RPCs + subscription
against a live daemon.
Known unrelated daemon gap (to be fixed next): pre-existing streams
aren't actually re-linked when the daemon writes target.object —
WirePlumber updates metadata but doesn't tear the old link down or
create a new one into the processed sink. Bus DSP path therefore
sees silence even when status reports route=processed. Not Phase 5;
addressed separately.
