# Phase 1.0BB: source-only launch-canary profile

Status: `REMOTE_BOUND_SOURCE_PROFILE_COMPLETE_BUILD_PREREQUISITE_AUDIT_ONLY`

Date: 2026-07-29

RetroArch commit `b0f5178e5acb59172fb352098d2ba32e5c42831b` adds the
BA-authorized post-S15/pre-`_Exit` terminal call and a distinct
`launch-canary` profile. The profile inherits write-diag startup, SDL overlay,
write firewall, inherited stdout and bounded runtime behavior. No launcher
identity enters the payload bytes.

All host C/sanitizer tests, existing parser/runner tests, historical source
validators, the BB mutation tests and PS5 structural validation passed. No
launch-canary ELF or map was produced. The source commit was pushed to and
read from the private Gitea origin.

Only an offline prerequisite audit may now determine whether the exact pinned
SDK, SDL archive, linker script, write wrappers and expected object graph are
present and hashable. This phase does not authorize a cross-build, artifact,
runner activation or device action.
