Phase 1.0M write-free defaults correction
Status: OFFLINE ARTIFACT AUDITED; DEVICE ACTION BLOCKED.
The consumed Phase-1.0K trace identified one blocked MKDIR before I04, and
Phase 1.0L bound it to the built-in playlist directory creation in
config_set_defaults(). Phase 1.0M makes only the corresponding offline source
correction in the separate chimera-retroarch fork.
For CHIMERA_PS5_NO_FILESYSTEM_WRITES, RetroArch now skips the directory
existence probe and path_mkdir() at that source site. It still calculates
new_path and all subsequent in-memory playlist paths. The write-diagnostic
profile has HAVE_CONFIGFILE=0, so the separate legacy migration block is not
compiled. All 17 --wrap write-firewall options remain in the link contract.
Static callgraph delta
The exact old Phase-1.0J function contained:
0x26845 -> path_is_directory
0x26856 -> path_mkdir
In the exact Phase-1.0M ELF, config_set_defaults retains six calls to
fill_pathname_join_special for this playlist block and contains no call to
path_is_directory or path_mkdir. The generic path_mkdir symbol remains in
the binary, but is no longer reachable from this defaults function. Link-time
garbage collection retains the actually referenced __wrap_open,
__wrap_fopen and __wrap_fwrite; each still enters the common fail-closed
write blocker.
Reproducible artifact
Two clean builds from RetroArch source commit

The ELF remains ET_DYN, entry 0xff220, with R-X, R-- and RW- LOAD
segments and no RWX LOAD segment. Init/fini arrays are empty, TLS is absent and
BSS is 697,632 bytes. It has 142 undefined dynamic symbols, seven DT_NEEDED
modules and 1,055 relocations (142 GLOB_DAT, 913 RELATIVE). send is the only
network primitive; socket creation, connect, listener, receive and GNM imports
are absent.
The artifact, map and audit JSON remain ignored local evidence and are not committed. The SDK v0.41 CRT effects remain inherited under ADR-0010. Static acceptance by the hardened-loader model is not runtime proof.
All current authorization fields are false. This new artifact is
execution_eligible=false, transfer_eligible=false and
installation_eligible=false. No PS5 connection, request, transfer, result
reception, execution, device write, retry or reconnect occurred in Phase 1.0M.
The Chimera GFX whole-tree secrets scan passed. The sibling RetroArch changed-file scan found zero matches; its whole-tree scan separately flags pre-existing upstream BearSSL/mbedTLS sample-key fixtures, so no whole-tree RetroArch PASS is claimed.
