+**SHIPPED 2026-07-17 (session 5):** gogobee `7e59697`, Pete `6c6de56`. All tests
+green both sides, gofmt-clean, screenshot-verified day + night (all six verdict
+chips, including the purple `new` chip the theme-contrast history warned about).
+NOT deployed. Additive private `Compare` field → safe deploy order either way.
+
+**The one both-sides error, and it overturned a settled design decision: the game
+only ever wears one ring.** `DnDSlotRing2` is declared and looped over as a valid
+slot, but nothing in live code assigns to it — every ring in the registry is
+`Slot: ring_1`, and the only equip path (`applyMagicEquip`, the same one ask 5's
+web button drives) equips to `mi.Slot`. So "weaker of the two worn rings" (the
+verified-at-scope proposal below) describes a trade that can't happen. The shipped
+behaviour: a backpack ring compares against the `ring_1` occupant — which collapses
+the ring special-case entirely, since **every** item's compare target is just
+`mi.Slot`. Even a section written after verifying both repos carried the class of
+error the rest of the spec did; the ring-slot subtlety was flagged "confirm before
+building" and the confirmation is what caught it. (Owner was asked; chose ring_1.)
+
+Everything else below shipped as written: strict-dominance verdict, engine-computed
+deltas over tempered effects (reusing `magicItemEffectFor`, no Pete-side math), the
+inert override that counts bonds *after* the slot's occupant is evicted, always-
+visible verdict chip (no hover — phones don't have one) with deltas beside it. Chip
+colours mix a fixed hue into `--ink`/`--card` so they survive all four phases by
+construction (the map's trick), NOT a `dark:` variant. The mobile hover→tap
+disclosure the spec proposed was dropped: deltas are short (≤3 chips), so showing
+them inline is simpler and needs no JS.

 A sixth ask, scoped after all five shipped. On the owner's own page, hovering a
 backpack magic item shows a **compare card**: the item currently worn in that
