Cli::Run is the whole client but its transport, so tests run it in
process against a real Session; main will hand it the QUIC connection.
- Commands: ls, status, cmds, help, call, get, set, pause, resume,
step, wait, trace, log (with --follow), screenshot, quit, debugger,
guide and version, with -i, --json and --timeout.
- call types key=value from the command's argument schema (slot=1 is
a number, name=1 a string, at.x=3 nests), so agents need no JSON
for simple calls; a value that cannot fit its field is a usage
error before anything is sent.
- The instance comes from discovery; one running instance needs no -i.
The record's protocol is checked before any request: a mismatch
exits 4, says which side is newer and prints the app's own client.
Other sources only warn.
- A request with no reply is diagnosed: the app has exited, stopped
in a debugger (with the attach command), or no longer calls Pump
(with what to change). Exit codes: 2 usage, 3 no instance,
4 version, 5 timeout, 6 the app's error.
- Output is short by default, arrays cut at 20 with a note; --json
prints everything. `guide` is the full reference for agents.

Crafter.Debug.Core is what the app side and the crafter-debug client
both need, without the session:
- Value: a JSON value with its own parser and printer, so no consumer
interface sees a JSON library. Integers stay integers and whole
doubles stay doubles; NaN and the infinities, which JSON cannot
spell, are written as strings rather than hidden, because a debugger
must not lose a NaN; invalid UTF-8 is replaced so output always
parses. Objects keep insertion order, the order an agent reads.
- Reflect: aggregate members and names through structured-binding
packs and source_location, taken from Crafter.DB, plus scoped-enum
names by probing a range of values. Self-tested with static_asserts
so a compiler that changes function_name()'s shape fails the build.
- Codec<T>: encode, decode and describe for bool, integers, floating
point, strings, enums, optional, vector, array, string-keyed maps,
Value, Required<T> and every aggregate. Decode reports every
problem in a call with its path and, for a typo, the likely intended
name, and never throws: a bad call cannot take an app down, which a
wrongly typed parameter could in 3DForts' hand-written from_json.
- Result, Error and Async: handler results, including ones that take
frames to arrive, so callers need no ready:false polling.
project.cpp now builds Crafter.Debug.Core as its own library, used by
both the app library and the client.
