Targeting an NPC whose faction you are Exalted with no longer opens a script error. `UnitReaction` answered 8 there, and stock `TargetFrame_CheckFaction` indexes `UnitReactionColor[reaction]`, which has seven entries (`TargetFrame.lua:6-14`, `:183`).
- **The cap.** `UnitReaction 0x6061e0` takes `0x606530`'s answer through `min(rank, 6)` at `0x606439` (`cmp esi,6` / `jl` / `mov esi,6`), so Revered and Exalted both read 6, and the Lua binding adds one (`0x51683e`), so Lua sees at most 7. `ring_reaction` now caps its answer there.
- **The ladder stays whole.** `reputation_rank` is untouched: the reputation pane and the item requirement lines still read Exalted.
- **Every caller** of `ring_reaction` models `0x6061e0` and tests at 1, 3, 4 or 5, so none changes but the four Lua unit feeds (target, targettarget, npc, mouseover), which now share one `unit_reaction` helper. The vendor discount's Exalted row reads as Revered, as in the reference, and still takes 10%.
- **Comments** that gave the scale as 0..7 or 1..8 now say 0..=6 and 1..=7.
Checked: `the_reputation_rank_is_capped_at_revered` walks both sides of the Honored, Revered and Exalted thresholds; `an_exalted_npc_target_reads_revered_and_its_plate_is_green` runs stock `TargetFrame` on an Exalted Stormwind unit. With the cap loosened to 7 both fail, the second with the issue's `TargetFrame.lua:183: attempt to index field '?'`; restored, both pass. Gates green on macOS; no platform seam touched.
