+# Phase 1.0L write-firewall result analysis
+
+Status: **ONE-SHOT AUTHORIZATION CONSUMED; FIRST WRITE IS MKDIR**.
+
+The exact ignored Phase-1.0J artifact ran once on firmware 9.60 through the
+manifest-gated Phase-1.0K runner. The host received a valid terminal trace
+with no parser error, retry or reconnect:
+
+```text
+D00 D01 D02(0) I00 I01 I02 I03 D13(6,1) D12(6,118)
+```
+
+`D13` is source-defined as `(first_blocked_write, write_block_count)`. Enum
+value 6 is `CHIMERA_SMOKE_WRITE_MKDIR`; the count was one. `D12` records
+shutdown reason 6 (`WRITE_FIREWALL`) and first error 118
+(`E118_WRITE_BLOCKED`). The J guard observed shutdown and returned before I04,
+so this run did not enter SDL, VideoOut or rendering.
+
+## Bounded cause
+
+The exact source, map, disassembly and relocation evidence agree on this
+bounded call chain:
+
+```text
+I03
+  -> retroarch_parse_input_and_config()
+  -> config_load()
+  -> config_set_defaults()
+  -> built-in playlist default-directory check
+  -> path_mkdir()
+  -> path_mkdir_cb
+  -> mkdir write-firewall wrapper
+  -> chimera_ps5_smoke_block_write(MKDIR)
+```
+
+The source site is `configuration.c:3357` at artifact source commit
+`2e385265ab893dbba5898178dde5e108d3dbfa19`. The ELF map binds
+`config_set_defaults=0x22ba0`, `path_mkdir=0x188f0` and
+`chimera_ps5_smoke_block_write=0x466d0`. Disassembly contains the conditional
+`path_mkdir` call at `0x26856`. The `path_mkdir_cb` relocation at `0x17c280`
+resolves to the wrapper at `0x15ae0`, which passes operation value 6.
+
+The runtime pathname was not included in D13 and is therefore **UNOBSERVED**.
+This evidence proves the operation category and compiled source route, not an
+on-device path identity or successful filesystem mutation. The firewall
+returned failure; no project filesystem write is evidenced.
+Normal SDK CRT effects remain inherited under ADR-0010, so the run is not
+classified as globally side-effect-free.
+
+## Next offline boundary
+
+A later artifact phase may make one scoped source correction: when
+`CHIMERA_PS5_NO_FILESYSTEM_WRITES` is defined, skip the built-in playlist
+directory creation in `config_set_defaults` while preserving all in-memory
+path derivation and every write wrapper. It must then rebuild twice, re-audit
+the complete artifact and remain ineligible. It must not weaken the firewall,
+permit a real mkdir, infer a device path, or inherit this consumed authority.
+
+The historical H flip result remains separate. This K run intentionally never
+reached the dormant J D07 errno instrumentation, so flip errno, successful
+presentation and cleanup remain unproven.
+
+All current authorization and eligibility values are false. There is no
+connection, transfer, execution, result-receive, retry or reconnect authority.
