Module samples 

Built-in demo chunks assembled with crate::ChunkBuilder.

Use these as runnable specs of the messaging contract (and as regression tests). Prefer copying a sample over inventing hop register layouts from scratch.

Sample	Shows
add_forty_two	Scalar VM path (no natives)
ping_pong	Cap spawn + Atomic Hop round-trip
atomic_request_reply	Tagged REQ/REP + print
selective_receive	ReceiveMatch FIFO skip
ask_reply	Ask RPC hop
forged_sender_send / forged_sender_ask	S1: forged make_msg sender dies
boom	Immediate trap (supervisor demos)

Hop samples require crate::std_native_table.

Constants

TAG_JUNK

Decoy hop for selective_receive ÔÇö must be skipped by ReceiveMatch.

TAG_PING

TAG_PONG

TAG_REP

TAG_REQ

Protocol tags for Atomic Hop samples.

Functions

add_forty_two

r0 = 41 + 1; return r0 ÔÇö the 60-second sanity chunk.

ask_reply

Atomic request/reply via Opcode::Ask (RPC hop).

atomic_request_reply

Atomic request-reply with crate::Value::Message (one envelope per hop).

boom

Immediate Trap ÔÇö used to show crate::Supervisor restart.

forged_sender_ask

Same security property as forged_sender_send, via Opcode::Ask.

forged_sender_send

Security regression sample: forged make_msg sender must not survive Send.

ping_pong

Two flows, one Atomic Hop round-trip: main sends a Message to pong, pong replies with payload+1 via msg_reply_cap, main returns that payload (2).

selective_receive

Selective Atomic Hop: server waits for TAG_REQ while a TAG_JUNK hop sits ahead in the mailbox (FIFO skip, not drop).
