# Phase 1.0AY: offline RetroArch target-source base reassessment

Status: `EXACT_PHASE10N_BASE_SELECTED_HOST_SOURCE_PATCH_ONLY`

Date: 2026-07-29

The local primary RetroArch checkout remains on the historical loader-diagnosis
branch. It is not switched or rewritten. The exact source base selected for the
next isolated worktree is private commit `606909706f91d7213751c245081333f56c2cce89`,
the inactive Phase-1.0N runner tip.

That commit descends from Phase-1.0M, contains its artifact audit and preserves
all target-source blobs relevant to AX byte-for-byte. Its Makefile difference
adds only inactive N runner validation. This makes it the least-lossy base and
avoids replaying the completed M/N history onto the older checkout.

The next patch is limited to host-tested source structure: cleanup-failure
accounting, `CHD10AV1`, D14 and its cleanup predicate. It may not add a target
profile, cross-build, artifact, launcher-specific define or runner activation.
Every hardware and build authorization remains false.
