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.
