Splits creature speed into two clocks so movement pace can be tuned without touching reaction time:
- **Think clock** — `ActiveSpeed`/`PassiveSpeed`/`CurrentSpeed`: seconds per AI decision. Unchanged in meaning, storage, and cadence.
- **Move clock** — `ActiveMoveSpeed`/`PassiveMoveSpeed` (+ resolved `CurrentMoveSpeed`): seconds per step. `0` = inherit the matching think value.
### How
- Move speeds come from optional `activeMove`/`passiveMove` in `npc-speeds.json`, are `[props`-tunable per instance (set `0` to re-inherit), and serialize (BaseCreature v22).
- `SetSpeed()` keeps its legacy one-clock semantics — sets the think clock **and clears move overrides** — so existing callers cannot half-configure a creature. `SetMoveSpeed()`/`ClearMoveSpeed()` configure movement explicitly; `ScaleMoveSpeed()` scales overrides for buffs.
- `CurrentMoveSpeed` is derived by classifying `CurrentSpeed`: a verbatim active/passive think value maps to the matching move value; a bespoke pace written directly (mount boosts, follow sprint) stays fused to both clocks. External `CurrentSpeed` writers need no changes.
- `AITimer` schedules the earlier of the two deadlines. Decisions run at the think cadence exactly as before; while a pursuit/investigation is live, the timer also wakes when the movement budget elapses and advances one step with no decisions. Steps no longer snap to the think grid, so any step delay paces smoothly on the 8ms wheel. A blocked creature schedules no move wakes.
- The movement budget is RunUO's `m_NextMove` accumulate-and-clamp at a full step, so long-run pacing averages `CurrentMoveSpeed` exactly.
### Behavior changes
- **`npc-speeds.json` buckets get RunUO `TransformMoveDelay`-parity move values**: creatures step at RunUO pace while thinking/reacting at current speed. The situational +0.1/+0.2 offsets are deliberately omitted.
- **Existing saves migrate on load**: a pre-v22 creature whose think speeds still match its npc-speeds entry (never hand-tuned) adopts the table's move values — worlds and pets pick up the new pacing without a respawn. Tuned creatures keep movement inheriting their think clock.
- **Paragons scale movement by `SpeedBuff` (1.2x)**: RunUO had no deliberate policy here — dividing by 1.2 knocked most speeds off `TransformMoveDelay`'s exact-equality table (raw pass-through, 2x+ faster), while 0.3/0.6 creatures landed back on it for ~1.33x. This applies the uniform 1.2x the buff always claimed. UnConvert snaps speeds back to exact table values within 1e-4 — /1.2 then ×1.2 drifts 0.45 and 0.9 by an ulp, which would read as hand-tuned (and defeat a future skip-table-conformant-values serialization pass); tuned speeds keep.
- **Herding paces the movement clock**: the old `CurrentSpeed` getter hack is gone. A herded creature walks at a fixed 0.3s/step — RunUO's forced pace, without its `TransformMoveDelay` inflation to 0.6 — so herding is never penalized by a slow creature. Thinking is untouched, and `CheckHerding` walks through `MoveToPoint`, so herded creatures path around obstacles.
- **Badly-hurt slowdown now inflates the step delay only** (RunUO parity), computed from the base each step. Previously it wrote `CurrentSpeed = CurrentSpeed + 0.05..0.15` back on every successful step — compounding unboundedly while hurt and slowing decisions too.
- Removes the vestigial `MoveSpeedMod` (never read, written, or serialized).
- With no bucket or per-instance move values, both clocks carry identical values and creatures pace as before.
### Testing
- Full suite passes (1557, including 12 new `MoveSpeedTests`: resolution classes, `SetSpeed` clearing, `0`-re-inherit, v22 round-trip with exact-consumption check, save migration adopt/skip, buff scale/snap, herding).
- In-game verified via local diagnostics build (per-step budget tracing): steady 700ms step cadence on a 0.3s think grid with one-step catch-up after idle, think grid unperturbed by move wakes.
The Throwing skill shipped with `StrScale`/`DexScale`/`StatTotal`/`StrGain`/`DexGain` all `0` in `skills.json`, so training it never raised Str or Dex — unlike every other weapon skill.
Fills those in by mirroring **Archery** (the Dex-primary ranged analog, which matches Throwing's existing `PrimaryStat: Dex` / `SecondaryStat: Str`): `StrScale 0.025` / `DexScale 0.075`, `StatTotal 10`, `StrGain 0.25` / `DexGain 0.75`.
Data-only change.
## Summary
Removes the dated `DynamicJson` JSON helper and migrates spawner JSON (de)serialization to a polymorphic `record SpawnerDto` hierarchy. `DynamicJson` was the last remaining consumer (regions moved off it in #1400).
The key correctness improvement: **System.Text.Json deserializes plain DTO records, never a live `Item`.** Previously, deserializing directly into an `Item` meant STJ constructed world-registered objects *before* the data was validated — a malformed/hand-edited spawn file could leave orphaned spawner Items in the world save. Now a parse failure is GC-only; `dto.ToSpawner()` constructs the spawner only from a fully-validated DTO and self-cleans on failure.
## What changed
- **New:** `SpawnerDto` (abstract) + `SpawnerDataDto` / `RegionSpawnerDto` / `ProximitySpawnerDto`, each marked with a reusable `[JsonDiscoverableType]` opt-in attribute. Auto-discovered at the `Configure` phase — no manual registration list (avoids the regions `Register<T>()` footgun), open to custom spawner subtypes.
- **Symmetric mapping:** `BaseSpawner.ToDto()` (export) ⇄ `SpawnerDto.ToSpawner()` (import). `ToSpawner()` deletes-and-rethrows on any failure, so the importer can never orphan an Item.
- **`SpawnerJsonSerializer`** wires `$type` polymorphism on the `SpawnerDto` root with loud collision/constructibility validation.
- **Import/export commands** rewired to the typed DTO path (reflection `FindTypeByName`/`CreateInstance` removed).
- **Data migration:** the 109 `Distribution/Data/Spawns/**` files moved from `"type"`→`"$type"` and legacy `homeRange`→`spawnBounds`. The runtime still *reads* legacy `homeRange` for external files. The `homeRange→spawnBounds` formula is proven equivalent to the runtime conversion (`BoundsEquivalenceTests`, hr=0/1/3/7).
- **Deleted:** `Projects/Server/Json/DynamicJson.cs`.
Sparse export output matches the legacy `ToJson` (nullable DTO properties + `WhenWritingNull`). Binary world-save serialization is untouched.
## Tests
- DTO round-trip per spawner type; sparse-default omission; legacy `homeRange` read; export/import file round-trip.
- `Import_MalformedFile_LeaksNoWorldItems` — proves a mid-array parse failure constructs zero world Items.
- `AllSpawnFilesLoadTests` — every migrated spawn file deserializes and builds.
- Duplicate-discriminator validation.
- UOContent.Tests 485/485, Server.Tests 710/710, build clean.
## Follow-up (not in this PR)
`Rectangle3DConverter.Write` (in `Projects/Server/`) omits `z1/z2` when `Start.Z == -128`, so a future server-side export of a `homeRange`-style spawner round-trips depth 256→255. Pre-existing and out of scope here (Server change); the migrated data reads correctly. Worth a separate small converter PR.
### Summary

## Setup
* Setup as part of decorate when bounty system is enabled
* Several bounty board locations with a WarriorGuard spawner in front of the board. Guard spawns and idles around 5 range.
## Tests
### ReportBountyMurdererGump
* Follows same behaviour as ReportMurdererGump
* Extracted common logic
* Didn't use staticgump due to several dynamic parts including input
* Optional bounty with validation >0 and <bankbox.total
* Murder report is honored either way
### Bounty boards
* Open bounty board with many bounties, no bounties
* Keep a bounty board open, invalidate a bounty by turning in the head, then try to click on the post of the now invalid post. As expected: does nothing
* Bounty messages use the last murder time as their post date and expire in 14 days
* Bounty boards/messages are not reliant on serialization; they use serialized fields from MurderContext to build messages when clicked.
* Bounty messages use synthetic serials so they do not have to persist bounty messages as items. They are constructed and sent as raw packets when needed.
* Players only appear on the bounty board if they are a murderer (though a non-murderer can technically still have a bounty if they decayed kills)
* Tested skin/hair color descriptions vs a dozen spot checks
### Head turn in behaviour
* Guard accepts head
* Bounty -> gives bounty
* No bounty -> generic response
* Expired head (24h) -> generic response
NOTE: CUO "latest" has a bug with bounty/bulletinmessages that causes overflow outside of the container. It has nothing to do with this PR. It is fixed here in CUO https://github.com/ClassicUO/ClassicUO/pull/1871
# Murderer title
Bounty system and "murderer" title eliminated in [pub16](https://uo.com/wiki/ultima-online-wiki/technical/previous-publishes/2002-2/publish-16-part-2-5-23rd-july/). So UO:LBR and before had bounties and murderer title.
# Pre-T2A caveat
There were differences in pre-T2A, but this cannot be currently implemented because we do not have any pre-T2A systems in general, so at least for now, behavior is consistent with later eras. Pre-T2A was a whole other ballgame, but the bounty system still worked similarly.
### Summary
- Add z-restricted spawnBounds to 35 spawners across 15 files to prevent creatures from spawning on incorrect floors
- Building spawners (Pyramid, Fire dungeon, Shame, Vendors) use minZ = spawner_z to prevent spawning below
- Ground level spawners (Graveyards, Outdoors, Tokuno) use minZ = -128 for natural terrain variation
- Multi-floor structures in Ilshenar use floor-specific Z restrictions
### Test plan
- Verify spawners in Fire dungeon building don't spawn creatures on floors below
- Verify Pyramid spawners keep creatures on their respective levels
- Verify ground level spawners (graveyards, outdoors) still spawn correctly on terrain
- Check Ilshenar multi-floor structure spawns creatures on correct floors
### Summary
* Unifies reading UOP File indexes
* Adds ArtData file reader to get graphic bounds
* Automatically generates Bounds.bin from art file if missing
* Adds [GenBounds command to regenerate the bounds.bin file. Useful for when the art file changes.
> [!IMPORTANT]
> Please read through these changes, as they changed certain expectations for how the internal AI thinking/movement work.
> Note that some mobs still don't have smooth movement on ClassicUO due to how the client handles animations/movement.
### Summary
- **Important Change**: Mobs will now move at a more regular pace. If the OnThink results in a move, but the cooldown would otherwise prevent the move, then the movement is scheduled on another timer.
- Added a 400ms delay to mobs turning to face a player to attack in order to avoid glitching between moving and turning.
- Reverted AI thinking speeds back to RunUO specific speeds.
- Reverted the AI thinking to moving conversion delays back to RunUO.
- For thinking speeds that are not exactly the predefined speeds from RunUO, there is a new calculation to determine the correct conversion to movement speed. This stops speeds like `0.35` from being faster than `0.3`
> [!NOTE]
> **Developer Note**
> BaseAI.CheckMove() no longer contains the check for whether or not a mob is on movement cooldown. This function can now be overwritten without causing issues to figuring out that cooldown.
### Summary
- Fixes `[AdvancedSearch` being accessible by players 😱
- Adds `[GenCommands` to generate the same commands html page on https://muo.gg/commands.
- Fixes `[helpinfo` so all commands properly show up!
> [!WARNING]
> ### Developer Warning:
> Commands must now be registered in the `Configure` bootup phase.
> If a command is not registered early enough, it may not be available to systems like [helpinfo
> that cache their information.
> [!NOTE]
> ### Developer Note:
> Various commands related to generating content have been changed to _Developer_ and above access level.

### Summary
- Adds the following configurations:
```json
"stats.statMax": "125",
"stats.gainChanceMultiplier": 1.0,
"stats.primaryStatGainChance": 0.75,
"stats.gainDelay": "00:10:00",
"stats.petGainDelay": "00:05:00",
"stats.usePub45StatGain": "False"
```
- Adds Pub 45 stat gain rate for UOML+.
- Reduces the gain delay for legacy stat gain from 15 minutes to 10 minutes.
- Legacy gain no longer requires a gain in skill to gain in a stat.
### Summary
- [X] Gets rid of the Dtos
- [X] Simplifies the json serializer registration
- [X] Adds a custom `RegionByName` JsonConverter that can look up other regions that have already been registered.
### BREAKING CHANGE
1. **Child regions must appear after their parents in the JSON file**
2. In the regions json file, _"Parent"_ can no longer be just a string. It must be an object that includes the map.
- ```json
"Parent": { "Name": "Britain", "Map": "Felucca" }
```
## Possible Breaking Change
* Reverted regions.json back to RunUO until newer regions are implemented and proper expansion checks are added.
### Other Changes
- [X] Adds `Region.IsPartOf<T1, T2>()` to check for multiple types.
- [X] Fixes regions.json being wrong
- [X] Adds lots of missing regions. **They are not implemented properly yet**
- [X] Adds regions.xml -> regions.json (check ModernUO Discord)
- [X] Adds expansion specific regions.
* Removes scaled speed by dex for monsters
* Changes scaled speed by dex for pets (HS+ expansion) to be 400ms -> 100ms between 50 -> 200 dex
* Removes speed changes that were broken for various mobs
* Combines "Legacy" speed and renames the class to `NPCSpeeds`
* Creates speed "classes" (slow, medium, fast, very fast)
* Introduces a new overridable property `SpeedClass`. Register a new speed class using `NPCSpeeds.Register()` and then set the speed class to bulk/mass apply speeds.
Order of speed determination:
1. SpeedMod
2. SpeedClass property (not null)
3. SpeedClass entry in Data\npc-speeds.json for that type
4. "Fast" (200ms Active, 400ms Passive)
