commit 51a9f322482586cd0c5120fc5fd42fb3dd6c45b4
Author: Fintan Halpenny <fintan.halpenny@gmail.com>
Date: Wed Dec 17 14:24:09 2025 +0000
protocol/connections: testing Connections
Adds property based tests to ensure the correctness of the
`Connections` logic.
The basis of the tests is to ensure that the state transitions are
correct, and that the machine cannot end up in an unexpected state.
There are also tests that ensure that certain state is preserved
across transitions, as well as other domain logic.
Disclaimer: the basis of the test suite was generated using Claude
with human input on what properties to start off with. All generated
code was reviewed for correctness and modified to fit the style of the
project as best as possible.

protocol/connections: noting not using the address during connected
The address is only used in the case of a fresh inbound connection but
is ignored if the connection existed or is an outbound case.
Adding a note to investigate this behaviour, and add a
`debug_assert_eq` for the time being.

protocol/connections: ensure no sessions for local node
Ensure that a `Session` is never created for the local node by
carrying the `NodeId` and guarding against it when calling state
transitioning methods.

protocol/service: wire up connections management
This replaces the `Sessions` logic by using `Connections`.
Wherever there was a use of `Sessions`, `Connections` is now used to
drive the state forward.
There are two ways we use the commands, paired with the I/O actions.
The first is to provide the command before the I/O action, so that the
state can be checked and validated that it can transition,
e.g. `connect` to see if a connection can be made.
The second is the I/O action drives the updating of the state that is
reflective of the real-world, e.g. `connected` since an inbound
connection was made. Note that further actions may be take from events
output here, for example, disconnecting the connected node because the
running node is at its limit.
It also removes the configuration constants in `service` to
consolidate them into the one module `connections::config`, and reuses
values set via `connections.config()`.

protocol/connections: refactor config
Refactor the configuration of connections.
This places the config types and values into their own sub-module.
It then refactors to have more logical units for sub-configuration:
durations, inbound, and outbound.
It also defines the constants that can be used as the default values,
which will replace the constants defined in `service`.

protocol: connections manager
This change defines the connections manager in a sans-IO fashion.
The goal is to have on-par behaviour with the management of connection
sessions that exists in the current `Service`.
It does this by using the `Sessions` state, defined in the previous
change, and pairs with commands and events.
The commands indicate what inputs the `Connections` state can receive
for changing the state of the sessions, and the events are the outputs
for those changes.

protocol: session state
This change introduces session state as part of the sans-IO rewrite of
connection management. It is similar to the `Session` and `Sessions`
types that are defined as part of `service`.
Where the `Session` and `Sessions` type differ is by providing a
generic type for keeping track of which state they are in: initial,
attempted, connected, or disconnected. The nodes in each state are
then kept track of in individual maps – one for each state.
The transition logic and mutation of session state are all
encapsulated in this module, so as not to leak these details.
The other benefit of using the generic parameter allows us to define
methods that are specific to a specific state for a session,
e.g. being able to ping a connected session.

+//! State management for node connection states.
+//!
+//! # Session
+//!
+//! The main type to describe a node connection is [`Session`]. It has a single
+//! generic parameter that describes the current state the session is in, which
+//! is one of:
+//! - [`Initial`]
+//! - [`Attempted`]
+//! - [`Connected`]
+//! - [`Disconnected`]
+//!
+//! Or, if a collection of sessions in various states is required, then
+//! [`State`] enumerates all of them.
+//!
+//! The are two main ways to construct a [`Session`]:
+//! - [`Session::outbound`]
+//! - [`Session::inbound`]
+//!
+//! # Sessions
+//!
+//! The [`Sessions`] type keeps track of what the current state a [`NodeId`] is
+//! in, with its corresponding [`Session`].
+//!
+//! A given [`NodeId`] must only appear in one state at a given time, if a
+//! session for it exists.
