Phase 1.0AC fake-syscall contract

This contract is executable only against the exact built-in fake facade.

Synthetic operation	Accepted result	Rule
CREATE_STREAM	OK, ERROR	exactly once after a precommitted receipt
SET_NONBLOCKING	OK, ERROR	immediately after create
START_CONNECT	IMMEDIATE, PENDING, ERROR	contains no target or address
WAIT_WRITE	READY, INTERRUPTED, TIMEOUT, ERROR	remaining fake budget is rechecked
GET_SO_ERROR	ZERO, NONZERO, ERROR	mandatory after pending readiness
WRITE_BYTES	PROGRESS, ZERO, ERROR	positive progress cannot exceed remainder
WAIT_READ	READY, INTERRUPTED, TIMEOUT, ERROR	deadline wins a simultaneous readiness event
READ_BYTES	PROGRESS, EOF, ERROR	EOF is failure; total input is bounded
local close	OK, ERROR	one call after ownership; none if create failed

The facade accepts at most 1,024 scripted steps. One step may advance the fake clock by at most 60 seconds. These are model bounds, not proposed live values. Unused synthetic steps are logically discarded at close; physical memory erasure is not proven.

There is deliberately no adapter protocol, inheritance hook, address field, network import or live factory. A later phase cannot reinterpret this fake as device authorization.
