-`test/testenv` helper package (`libbyteid`, `wwi`, `asmwindow`,
-`freenoop`, `structabi`, `mangle`), each retired with its port in the
-same commit. Rows migrated to fixtures or native `@test`
-owners were removed from those carriers; there is no compatibility execution
-path for retired rows. 74 former byte/artifact carriers whose only assertion
-was a cstage-vs-wwstage `.s` byte-compare of sources now living in the
-corpus were retired into the blanket `test-data-byteid` comparator (the
-last 13 had their remaining inline sources added as fixtures first); the
-observations the blanket cannot subsume — assembly-pattern windows,
-symbol tables, `.wwi` round-trips, the wwstage-driver leg — are
-ww-native tests under `test/byteid/`. Wwstage-driver-leg byte identity
-(`ww_ww` versus `ww` over the emitted `.s` set) has one owner,
-`test/byteid/libbyteid_test.ww`, whose unit sweep spans the 44-entry lib
-roster (test fixtures, sentinel-guarded import probes, a zero-dep
-root-only build) plus the lib/ completeness scan; the former 815/940/951
-driver-parity carriers were folded into it, their content identity
-already owned by their corpus twins.
+16 native C carriers remain. They are partitioned exactly once as five
+in-process units, six bootstrap gates, one platform gate
+(`996_dyn_ww`), and four residual survivors, each held by a named
+terminal reason: `738_module_decl` (in-process parsefile calls — a
+C-bootstrap observer misfiled among the residuals; freezes with the
+units at the selfhost flip), `810_dyn` and `989_dynentry_run` (host
+loader/glibc claims — platform class), and `794_xmod_ident_prefer`
+(pins the OPEN wwstage bare-leaf fn-shadow cgen bug, a #55 sibling;
+its cstage-run + wwstage-build-accept assertion set is not
+fixture-expressible while the bug lives — it retires with the fix).
+
+The 2026-08-08 residual drain retired the other 107: 5 deleted against
+verified owners, 196 rows migrated into corpus fixtures (700_e2e's 136,
+the fixture-class 46, the 926/929/671 run legs), and the rest ported to
+ww-native observer suites on `test/testenv`, each carrier retired in
+the same commit as its replacement: `test/sep/` (sep-layout/driver),
+`test/xmod/` (module-tree collisions, mangle, typecheck, direnum),
+`test/asm/` (positional asm-window needle observers), `test/object/`
+(w6a/w6l ELF, archive, and link facts), `test/misc/` (divergence pins,
+stamp probes, wwi round-trips), `test/tool/` (driver CLI, wwdump
+gates, FFI, the c6 soak), and `test/libenv/` (the lib/os + lib/dirs
+env-arranger legs; those lib suites now pass bare with loud SKIPs).
+All suites run under `test-compiler`. The byte/artifact partition
+stays EMPTY under `test/byteid/` exactly as before; wwstage-driver-leg
+byte identity keeps its one owner, `test/byteid/libbyteid_test.ww`
+(44-entry roster plus the lib/ completeness scan). Known cs≠ww
+divergences exposed by row migration are pinned in
+`DATABYTEID_DIVERGED` (3 entries) on the graduation discipline.
