+### Addon check: raiders answer through shootyepgp
+
+* Every addon check (the **Check addons** button and the automatic check when
+  the tab opens) now also sends one `ADDONCHECK` query: `Q1:<id>:<folders>`
+  for BigWigs, TWThreat, shootyepgp, UpsiRinse, Rinse, RABuffs and
+  BetterCharacterStats. shootyepgp builds with the responder answer
+  `A1:<id>:<Folder>=L/<version>;<Folder>=D;<Folder>=M` (loaded with the
+  version from its `.toc`, installed but disabled, not installed), split into
+  messages of at most 240 characters.
+* An answer is certain and beats every passive rule and class rule in its
+  column: green with the version when loaded, red when not installed or
+  disabled (the tooltip says which). Rinse counts as loaded if either Rinse
+  or UpsiRinse is.
+* Versions from answers are compared across the raid like every other
+  version, so an older one gets the "!" mark.
+* Raiders without the responder are read exactly as before; silence is never
+  turned into red.
+
+### Own row
+
+* Your own row shows an addon you have installed even where the class rule
+  would call it not expected (Rinse on a class that cannot dispel).
+
+### Addons tab: RABuffs and BetterCharacterStats
+
+Two more columns on the Addons tab. Without an addon-check answer both are
+detected **passively** (nothing is sent for them, no visible chat, no
+whispers):
+
+* **RAB (RABuffs).** Any `RAB/BT` broadcast (every 30 s per client, only when
+  the member has mana or a tracked timed buff) marks the raider as present;
+  the version only comes from `RAB/V`/`RAB/VC`, which RABuffs has disabled
+  upstream but are parsed if they ever arrive. After 70 s in the raid without
+  any message the cell shows grey "Not seen" (never red); the tooltip says
+  this is weak evidence.
+* **BCS (BetterCharacterStats).** A `bcs` message starting with `TREE,` marks
+  the sending druid as present. Everyone not heard from and without an
+  addon-check answer stays unknown, never missing and never n/a (the message
+  only reaches the sender's own subgroup, and only in Tree of Life form).
+* The addon keeps track of when each raider first appeared in the roster for
+  the 70 s rule. Your own row reads RABuffs and BetterCharacterStats from your
+  own addon list. `/dc test` shows both columns.
+* The tab has two more columns, so the matrix is wider on this tab.
