# Phase 1.0BF: offline live SDL adapter boundary audit

Status: `LIVE_ADAPTER_CONTRACT_BOUND_SOURCE_ONLY_NO_INSTALL_OR_BUILD`

Date: 2026-07-29

The BE operation order can be implemented by a dormant local adapter only if
all paths resolve beneath the declared RetroArch build root, every argv is a
fixed sequence passed without a shell, identity output is bounded, each process
has a hard timeout, and fresh stage/build/archive paths are required. One
failure consumes the attempt; there is no retry, fallback, resume or automatic
cleanup.

The adapter may know only Git, CMake and Ninja operations needed for the exact
SDL archive. It may not contain apt/package installation, network, RetroArch
compilation, target address, device command or launch behavior. Patch checking
must precede patching, and the changed-file set must equal the three BD paths.

Local Ubuntu metadata identifies official repository candidates CMake
`4.2.3-2ubuntu2` and ninja-build `1.13.2-1`; neither is installed. This audit
does not authorize installation. It authorizes dormant adapter source with
fake-process tests only and no invocation against the real workspace.
