+# Pre13 Execution Status
+
+## Final Status
+
+Pre13 is **scoped PASS** for the planned and admitted Pre13 work at
+`b804d7b77d1c76b8e844dc4a758c6ab3381ca006`.  This is not a full feature-suite
+PASS and does not claim V02 positive coverage.
+
+At status backfill time, DUT `HEAD`, local `main`, fetched `xdm/main`, remote
+`refs/heads/main`, and the DUT worktree all resolve to
+`b804d7b77d1c76b8e844dc4a758c6ab3381ca006`; the DUT worktree is clean.

+
+## Stage0 Decisions
+
+- H04 ROOT-NONDIR: `READY`, then implemented and custom validated.
+- H07 ZERO-RUN: `STOP/no-op`; 1,360 legal states showed no reachable
+  zero-progress path.
+- H01a/b/c map request work: `STOP`; the tuple oracle lacked chunk,
+  multidevice, bounds, and overflow coverage.
+- H03 comparator: `READY`; Python 11,562 cases and C 1,048,576 cases passed.
+- Device-option probing: blocked/non-gating, no behavior claim.
+
+## Validation Status
+
+- Targeted build/layout/probe retry:
+  `/work/tests-dev/temp/pre13-targeted-final-runnerfix-retry-20260814T0138Z`.
+  `WITH_ZSTDIO=0` and `WITH_ZSTDIO=1` builds passed with module SHA256
+  `0b1244cf9b7fe70649bdcc1c6ef12e6151c77b10c2755b366f960b101ccb7220`
+  and `15db1fbf9450259d030e88602e1c5ba2e452a731c641b359bd5a2d7823da2735`.
+  Layout probe and four userspace probe builds passed.
+- H04 custom fixture: PASS.  Valid root mounted/remounted; non-directory root
+  returned exact `EINTEGRITY` (`97`); failed mount left the provider
+  detachable.
+- H03 targeted feature cases: PASS for TC042, TC043, TC044, TC045, TC053,
+  TC054, TC123, TC141, and TC148.  TC141's raw runner failure was an extra
+  empty `umount ''` false negative after 25 real commands passed.  TC148
+  covered 320 files, 322 dirents, content, and empty suspect dmesg.
+- Final smoke:
+  `/work/tests-dev/temp/pre13-missing-and-smoke-20260814T021330Z/final-summary.md`.
+  Plain, LZ4, and LZMA passed; KLD load/stat/unload and cleanup passed.
+- V01 race:
+  `/work/tests-dev/temp/pre13-v01-race-20260814T031032Z/retry-fresh-20260814T032500Z`.
+  Raw runner FAIL was reclassified by the final offline analyzer at tests-dev
+  `22c0bea73b9b81cc44385d1ba7103fa820c56070` as
+  `DUT PASS / TEST false-negative-corrected`.  The four offline analyzer unit
+  tests passed.  Dmesg total delta was 24 lines / 1,266 bytes with suspect
+  bytes 0.
+
+## Explicit Non-Claims
+
+- No full feature suite was run.
+- No V02 positive explicit-extent fixture was produced; V02 remains PARTIAL.
+- TC004, TC011, TC143, TC144, TC145, TC150, and other unlisted feature cases
+  are not claimed as passing.
+- H01, H07, H05, H06, H02, and H08 source changes were intentionally stopped,
+  rejected, or no-op as recorded in the final report.
+
+Detailed evidence and limits are recorded in `pre13-final-report.md`.
