 ### Fixed
-- Herb/ore categorization no longer guesses from display-name keywords. The old
-  `SplitByCategory()` matched "lotus"/"clover"/"thorn"/"bloom" for herbs and
-  "vein" for ore, which only worked for the original Northrend default pool and
-  silently fell back to the unsplit pool for almost every v2 zone (Outland/Classic
-  ore uses "Deposit", not "Vein"; most herb names match no keyword). Replaced with
-  a static ID→category lookup table built from the DB-verified entry IDs in
-  `docs/zone-specific-resources-spec.md`, with the old keyword check retained only
-  as a fallback for entries not in the table. See
-  `docs/herb-ore-category-fix-spec.md`.
 - Event start/end announcements no longer crash the server. `StartEvent()` and
   `EndEvent()` both used `ChatHandler(nullptr).SendWorldText(...)` to broadcast
   server-wide -- `ChatHandler::SendWorldText` assumes a real session and calls

-# Fix: herb/ore categorization breaks for almost every zone in the v2 pool
-
-## The bug, confirmed by reading the code
-
-`SplitByCategory()` (`GoldRush.cpp:648`) decides whether a resource entry
-is a herb or ore purely by matching keywords in its display name:
-
-```cpp
-bool isHerb = ContainsWord(name, "lotus") || ContainsWord(name, "clover") || ContainsWord(name, "thorn") || ContainsWord(name, "bloom");
-bool isOre = ContainsWord(name, "vein");
-```
-
-This was written against the *original 5-entry Northrend default pool*
-(Goldclover→"clover", Icethorn→"thorn", Frost Lotus→"lotus", Titanium
-**Vein**→"vein") and never updated when the v2 zone-resources feature (PR
-#5) introduced ~70 new resource names across 57 zones.
-
-**Confirmed failure case**: tested live in Hellfire Peninsula. Its
-configured pool is Felweed, Dreaming Glory, Fel Iron **Deposit**,
-Adamantite **Deposit**. None of these match any herb keyword, and neither
-ore entry contains "vein" — most Outland/Classic ore uses "Deposit," not
-"Vein." So both `herbEntries` and `oreEntries` come back empty, and
-`SpawnHotspot()` (`GoldRush.cpp:998-1017`) falls back to
-`fallbackEntries` (the whole site pool, unsplit) for every node. The
-intended herb/ore alternation silently never happens for the large
-majority of the 57 configured zones — only the handful whose names happen
-to contain one of the four hardcoded herb words or "vein" categorize
-correctly at all.
-
-**Observed symptom**: the test run in Hellfire produced overwhelmingly
-Felweed with no observed ore, despite the fallback pool containing ore
-entries. Whether that's pure sampling variance or a second, separate
-issue (see "Worth checking after this fix" below) isn't confirmed from
-reading the code alone — don't assume the placement-bias theory without
-testing after this fix ships.
-
-## Fix: stop guessing category from the name, use a known lookup table
-
-Every entry ID used across the 57-zone pool was already individually
-verified against `acore_world.gameobject_template` when the pool was
-built (`docs/zone-specific-resources-spec.md`). Rather than continue
-patching an ever-growing, ever-fragile keyword list — the next zone added
-will just as easily introduce another unmatched name — replace the
-name-based guess with a static ID→category lookup built from data that's
-already verified correct.
-
-**Add a lookup table** (e.g. `static const std::unordered_map<uint32,
-bool> IsHerbById` or similar, `true` = herb, `false` = ore), populated
-from every entry in the tables below. Change `SplitByCategory` to check
-this table first; **keep the existing name-keyword check as a fallback
-only** for any entry not found in the table (defensive — covers the
-original global-pool default entries and anything added by hand later
-without an explicit table update).

-(This is every entry that appears anywhere in `gold_rush.conf.dist`'s
-`GoldRush.ZonePool` plus the module's own default global
-`GoldRush.NodeEntries` — cross-check against both files while
-implementing, in case an entry was missed here.)
-
-## Worth checking after this fix — don't build blind for this part
-
-Once real ID-based categorization is in, re-test Hellfire Peninsula (or
-another Outland zone) with `.goldrush teststart` a few times. If ore
-still rarely/never appears despite `oreEntries` now correctly populated,
-look at the placement-validation loop (`GoldRush.cpp:1019` onward) —
-specifically the `MaxVerticalDrift` cliff/rock-face rejection. Ore
-deposits are commonly placed on steep terrain in the actual game world;
-if placement attempts for ore entries are failing validation far more
-often than herb entries, that's a second, separate bug worth its own fix
-— but confirm it's actually happening before changing that logic, rather
-than assuming.
-
-## Testing
-
-- Hellfire Peninsula (the confirmed failure case) should now show a mix
-  of Felweed/Dreaming Glory *and* Fel Iron/Adamantite, not all-herb.
-- Spot-check one or two zones whose original names *did* match the old
-  keyword list (e.g. Un'Goro Crater — Firethorn contains "thorn", Black
-  Lotus contains "lotus") to confirm the table-based path didn't regress
-  anything that used to work by keyword-coincidence.
-- Confirm entries not in either table (if any exist) still fall through
-  to the old keyword check rather than being silently dropped.
