limit has an explicit `body-size-limit` or `body-allocation-limit` unavailable

Additional implementation bounds are 16 simultaneous network-content reads,

| `128 + N` | Signal-derived status. An unhandled signal may have ended the process, with the shell or runtime preserving the conventional status; a command may instead have handled the signal, waited for its operation and cleanup to settle, and assigned the same status (`130` for SIGINT, `143` for SIGTERM). In the handled case, it may also have printed a structured `cancelled` result. |
|
||||
|
||||
A `cancelled` result does not by itself determine the exit status; it depends on
|
||||
the command's signal handling. Commands routed through the shared
|
||||
`withCommandCancellation` handler in the CLI set status `130` for SIGINT or
|
||||
`143` for SIGTERM after their operation settles. Current source registrations
|
||||
use that handler for process capture and comparison (`capture-process`,
|

`compare-process-captures`), JavaScript application analysis (`analyze` when it

selects the JavaScript lane, and `analyze-javascript-application`), selected

WASM/EVM, Go/Rust and binary diagnostics, Frida instrumentation, the Cutter

command, objdump, Rizin and GDB. In these paths, a returned structured
|
||||
`cancelled` result can be printed before the wrapper assigns the
|
||||
signal-derived status. This describes the current source routing; it is not a

claim that every command or provider runtime has been independently exercised.
|
||||
|
||||
`inspect-artifact` also returns a structured cancelled result, but its direct
|
||||
analysis cancellation path does not set a signal-derived exit status, so it
|

exits `1`. Setup has its own contract: cancellation exits `0`. Treat the

structured result and process status as separate signals when scripting

cancellation.
