Converts BaseCreature's hand-written v22 serialization to codegen v23.
Nearly every field sits behind a [SaveFlag], so a creature matching its
defaults writes only [version int][ulong flags][default AI] - 13 bytes -
instead of ~236, and the writer's work is mostly branch-not-taken. With
500k-1M creatures in a world, this is the dominant slice of mobile save
freeze time and disk.
- Speeds serialize only when they differ from the creature's npc-speeds
values (GetSpeeds/GetMoveSpeeds on both the flag check and the load
default), so table edits now reach existing unmodified spawns on
restart, and former paragons (snapped back to table values) elide
fully. CurrentSpeed writes only when it differs from PassiveSpeed.
- The delete countdown is a [DeserializeTimer] field (anchored);
stabled/controlled pets never persist one, and the abandoned-pet
3-day fallback lives in AfterDeserialization for both load paths.
- SummonEnd stays anchored, written only while summoned.
- Old saves (v0-22) load through the retained legacy
Deserialize(reader, version), now assigning raw fields; the shared
post-load fixups (stat timers, AI creation, followers, animate-dead
registration, unsummon timer) moved to [AfterDeserialization].
- Side-effect setters became generated-field hooks (Team, Controlled,
Summoned, Loyalty clamp, resistance seeds, CurrentSpeed); properties
whose semantics the hooks cannot express stay hand-written as
[SerializableProperty] (ControlMaster/SummonMaster bracket the
assignment with follower bookkeeping, ControlOrder must run on equal
re-assignment, Tamable/IsParagon/move speeds have custom getters).
- CreatureDeathEvent/CreatureDeletedEvent moved to a CreatureEvents
host class: the events generator and the serialization generator each
emit a [GeneratedCode] partial for the declaring type, and the
attribute forbids duplicates (CS0579).
- m_ fields renamed to _camelCase.
Tests: new-format round trips (default and fully populated) with exact
byte consumption, back-to-back saves byte-identical, and a
byte-authentic fossilized v22 stream loading through the legacy path.

Fixes#1690. Addresses Blood Oath holistically — three bugs found while researching the spell against RunUO, ServUO, the UODemise/uo.com guides, and the archived UOGuide page.
## Bugs fixed
### 1. Expiry timing (the filed issue)
The `ExpireTimer` polled every 1s, so expiry and death/delete cleanup lagged up to ~1s. Replaced with a **single-shot** timer plus centralized `[OnEvent]` handlers on `PlayerDeathEvent`/`PlayerDeletedEvent`/`CreatureDeathEvent`/`CreatureDeletedEvent` — the oath now breaks immediately on death/delete of either party.
### 2. Duration formula
Used `/80` (the bugged in-game tooltip value) instead of the real OSI formula `((SpiritSpeak - Resist) / 8) + 8`. Confirmed by RunUO, ServUO, the emulator guides, and the code's own fixed-point comment. At GM Spirit Speak this changes duration from ~9.5s to 23s and makes Spirit Speak actually affect duration.
### 3. Damage reflection (`BaseCreature.Damage` vs `PlayerMobile.Damage`)
`BaseCreature.Damage` diverged: it attributed the reflected hit to the attacker itself (`from.Damage(amount, from)`) instead of the caster, reflected the bonused (not original) amount, used `×1.1` vs `×1.2`, lacked the caster-survival guard, and had no Publish 48 resist mitigation.
Unified both paths: reflect the **original** damage attributed to the **caster** at `×1.2`. Publish 48 resist mitigation now applies only to creature casters and is gated behind `Core.SA`.
## Internals
- Collapsed the parallel `_oathTable` into a single `_table` keyed by both participants → shared timer, so `RemoveCurse` resolves from either side (required by the event handlers).
- Extracted `GetDurationSeconds` and `ComputeReflectedDamage` as testable statics.
## Tests
13 new tests (duration formula, reflection mitigation, oath lifecycle, end-to-end event-driven removal). Full suite: **436/436 pass**.
## Issue
Fixes#2452. A player with 30 Ninjitsu reported that the Animal Form menu showed **every** form; selecting one above their skill (e.g. Dog, req 40) **consumed mana** and returned "you need at least 40 skill", and afterwards the **gump never reopened** — every recast silently re-attempted the unusable form and drained more mana.
## Root cause
Three linked bugs, all reproduced from the code:
1. **Gump not gated by skill.** `AnimalFormGump.BuildLayout` compared `Skill.Fixed` (which is `Value * 10`, so 30 skill → `300`) against the raw 0–100 `ReqSkill` (Dog = `40`). `300 >= 40` is always true, so all forms were shown. `Morph` itself correctly uses `.Value`.
2. **Mana charged on a no-skill cast.** `Morph` returns `MorphResult.NoSkill` for an under-skilled form, but both call sites (`OnCast`, `OnResponse`) only special-cased `MorphResult.Fail`; `NoSkill` fell through to the branch that deducts mana.
3. **Menu never reopened.** Per OSI ([uo.com](https://uo.com/wiki/ultima-online-wiki/skills/ninjitsu/), [uoguide](https://www.uoguide.com/Animal_Form)), casting while **standing still always opens the selection menu**, and casting while **moving** quick-transforms into the last selected form. ModernUO only opened the menu when `lastAnimalForm == -1`, so once any form was selected a stationary recast skipped the menu.
## Fix
- Add `AnimalForm.CanSelectEntry` (compares `Skill.Value` to `ReqSkill`, plus the talisman check) and use it for the gump's per-entry enable check.
- `OnCast`: standing still always opens the menu; moving quick-transforms into the last form. `NoSkill` no longer costs mana.
- `OnResponse`: handle `Success` / `Fail` / `NoSkill` explicitly so `NoSkill` costs no mana.
## Tests
Adds `AnimalFormTests`:
- `CanSelectEntry` rejects forms above skill, accepts forms at/below skill, and requires a talisman for talisman-gated forms.
- `Morph` returns `NoSkill` (without transforming) when under-skilled, and `Success` when sufficiently skilled.
Verified the gating test catches the regression (reintroducing `.Fixed` fails it). Full solution build is clean; the 5 new tests plus 284 other UOContent tests pass (the pathfinding/AI sequential tests were excluded only because they deadlock under concurrent local runs — they are unrelated to this change).
