-## ci(conformance) -- wp18 gate third kind bitexact_selfconsistent (this PR, Closes #1182)
-
-- **CHANGED** `tools/wp18_conformance_gate.py`: Check B recount is now TRI-STATE
-  (bitexact / bitexact_selfconsistent / structural) instead of binary; INDEX key
-  `selfconsistent_packs` OPTIONAL (defaults 0) so a legacy 2-kind INDEX stays green;
-  unknown kind -> drift (never folded into bitexact).
-- **CHANGED** `conformance/vectors/gen_all_formats.py`: SELFCONSISTENT registry keeps
-  the affected packs verbatim + emits the `selfconsistent_packs` summary key.
-- **NEW** `tools/wp18_gate_selfconsistent_selftest.py`: 13 checks, 6 FAIL-reachable
-  controls. Patched gate on UNCHANGED tree: exit 0, recount [83,55,0,28].
-- catalog stays 83; ASCII-only; gate-side prerequisite for the INDEX-sync (#1146).
-- Closes #1182

+## wp18-gate-third-kind -- Check B tri-state bitexact_selfconsistent (Closes #1182)
+
+- **WHERE**: tools/wp18_conformance_gate.py, tools/wp18_gate_selfconsistent_selftest.py (new), conformance/vectors/gen_all_formats.py
+- **WHAT**: Check B recount changed from a binary model (bitexact unless structural) to a tri-state recount counting bitexact / bitexact_selfconsistent / structural separately. The INDEX summary key selfconsistent_packs is OPTIONAL and defaults to 0, so a legacy 2-kind INDEX recounts unchanged (backward compatible). An unknown kind is flagged as drift and is never folded into bitexact. gen_all_formats.py gains a SELFCONSISTENT registry (mirrors the EXISTING pattern) that keeps the affected packs verbatim under the new kind and emits the summary key.
+- **Why**: the wide GoldenFloat rungs (gf48/gf96/gf128/gf512/gf1024) are bit-exact by construction but only gf16 has an independent silicon oracle (Corona ROM); the third kind records the honest, strictly-weaker status so their vectors can enter the INDEX without overstating evidence. Gate-side prerequisite for the INDEX-sync (#1146). New self-test 13 checks, 6 FAIL-reachable controls; the existing wp18_selftest_gate.py stays 15/15; patched gate on the UNCHANGED tree exits 0 with recount [83, 55, 0, 28]. L6 gf16 SSOT untouched; catalog stays 83; no gen/ edits; ASCII-only added lines; no quality claim added. Closes #1182.
+- **Anchor**: phi^2 + phi^-2 = 3
