MossTank was casting cheapest-first. That is a reasonable rule for surviving
a mana shortfall and a bad one for everything else, because AC's buff order is
not a preference -- each group raises the skill the next group is cast with:
1. Creature Enchantment, and inside it:
- the Creature Enchantment skill itself, which every remaining creature
buff is then cast with;
- Focus, then Willpower, then Endurance -- Focus and Self are the
attributes the Item Enchantment and Life Magic skills derive from, so
raising them raises the skill groups 2 and 3 are cast with;
- the rest of the creature spells.
2. Item Enchantment -- the banes and weapon auras.
3. Life Magic last -- the protections and Armor Self.
Casting out of that order means casting at a lower skill than the character
could have had, which shows up as fizzles.
Grouping is by the spell's school rather than by name or category, so
protections land in group 3 because retail files them under Life Magic, not
because anything here says "protections go last".
Willpower is matched as "Self": retail's spell is named Willpower but its
description reads "Increases the caster's Self by 10 points", and MossTank
classifies from the description, so the name it matches is the one retail
actually writes. Verified against the spell table rather than assumed
(0x05A5 Willpower Self I).
Cheapest-first survives as the tiebreak inside a group, so a mana shortfall
still costs the cheapest of the last group instead of something the rest of
the pass depended on.
The two ordering tests were confirmed to fail when CastRank is neutralised --
the third guards the tiebreak and passes either way, by design.

Three whole categories of buff were missing, for two different reasons, and
both were my errors.
**Protections and weapon auras were silently dropped by the description
parser.** They are self-targeted and were sitting in the spellbook the whole
time, but retail words them differently and the pattern only accepted
"Increases the caster's X by N":
Fire Protection Self -> "Reduces damage the caster takes from Fire by 9%."
Armor Self -> "Increases the caster's natural armor by 20 points."
Aura of Blood Drinker -> "Increases a weapon's damage value by 2 points."
So the weapon and wand buffs do exist as self-cast "Aura of" lines and are now
cast. Each category has its own toggle, matching VTank's separate
BuffProfile_Prots and BuffProfile_Banes.
The underlying flaw mattered more than the two missing patterns: anything
unmatched was DISCARDED. It now falls into an Other bucket (off by default)
instead, so nothing self-targeted is lost without a word. A test caught a
second instance immediately -- regeneration spells say "Restores..." and were
vanishing the same way.
**Banes were excluded because I misread a flag.** I took IsSelfTargeted as
"can be cast on you". It means "needs no selection". Retail's own bane text
says exactly how they work:
"Increases a shield or piece of armor's resistance to slashing damage by
10%. Target yourself to cast this spell on all of your equipped armor."
So banes ARE cast on the person, and the catalogue now includes every
beneficial non-untargeted spell rather than only flagged self-casts, leaving
EvaluateGate to decide what a given target accepts. Before casting anything
without the self flag, MossTank selects the player -- and restores whatever
was selected before the pass, so targeting yourself does not quietly steal
the selection.
They are matched on retail's "Target yourself..." sentence rather than on the
word "Bane", so the classification comes from what the spell says it does.

Virindi Tank's own term: Force Buff recasts the lot rather than only what has
lapsed. The button now does that, and says so.
BuffPlan gained a force flag that skips the already-in-force check. Forcing
means "ignore what is already up", NOT "ignore the settings" -- the trained-
skill filter, the attribute toggle and the difficulty margin all still apply,
and there is a test pinning that.
The loop had to change shape for this. It used to re-derive the plan every
tick and treat "plan is empty" as done, which works only because the ordinary
plan shrinks as buffs land. A forced plan never shrinks -- that is the point --
so the same loop would have cast forever. A pass now captures a queue at the
start and works through it by index, which is also cheaper: no rebuilding 80-odd
buff lines every frame.
A spell that will not go now advances the queue rather than blocking it. One
missing component used to mean everything behind it waited for the stall
timeout; now the status line names the refusal and the pass carries on.

Three things from the first working buff pass.
**Pacing.** Casts were three seconds apart because of a fixed interval I added
before there was a real busy signal. There is one now -- the shared busy count,
incremented by the cast and decremented by the server's UseDone -- so the
interval is gone and the server is the only throttle. MossTank casts the moment
the previous action is acknowledged, which is the spam behaviour VTank has. The
stall timeout moved 25s -> 30s so a slow server does not read as a stall.
**Stamina to Mana was surprising.** VTank does convert vitals by default
(Recharge-*-Mana), so the behaviour is right, but a buff pass quietly spending
your stamina is not something to discover by watching. It is now a setting,
with its own thresholds, and can be turned off outright.
**Settings view.** Spell difficulty margin, rebuff time, the three vital
thresholds, and three toggles. Two details worth recording:
* The difficulty margin is SIGNED, per the VTank wiki: "a positive number
raises the skill necessary to cast spells, a negative number lowers it. To
attempt higher spells at a low level use a negative number." So the range
spans -100..+100 rather than starting at zero.
* It is a second registered panel with a complementary visible binding rather
than a tab control. Two panels and an Action need no new markup vocabulary,
and only one is ever on screen.
Adjuster buttons rather than typed fields: buttons are proven in plugin markup,
while an editable UiField would need keyboard routing plumbed through to plugin
panels first. Worth doing, but not as a side quest inside this change.
Also fixed: the App copy target names plugin files explicitly, so the new
markup would have been left out of the plugin directory and the settings panel
would have failed to load at runtime with the build perfectly green. Caught by
listing the output rather than trusting the build.

Reworks MossTank against user feedback and the Virindi Tank feature docs
(virindi.net is reachable again over https with a self-signed cert; the
research doc's "unreachable" note is stale).
VTank's stated default is the spec: "automatically buffs every Attribute and
Skill you have trained", and "all buff spells are recast when they go below 5
minutes". The previous pass buffed the whole spellbook and refreshed at 60s;
both are corrected.
The hard problem was working out WHICH stat each buff raises. The client's
spell table has no such link -- it arrives from the server with the
enchantment -- and the naming is too irregular to infer: Invulnerability
raises Melee Defense, Impregnability raises Missile Defense, Fealty raises
Loyalty, Sprint raises Run, Arcane Enlightenment raises Arcane Lore, and the
line called Willpower raises the attribute named Self. Any name-matching
scheme dies on that last one.
Retail states it outright in each spell's own description ("Increases the
caster's Life Magic skill by 10 points"), so BuffProfile derives the whole
mapping from shipped data at runtime. It also carries the one alias the data
needs: the spell text says "Assess Monster" where the skill table says "Assess
Creature", and without that the skill silently never matches.
Two data facts that would each have caused a real bug, found by dumping the
spell table rather than assuming:
* Family is NOT a spell-line identity in general. Retail groups the
instantaneous vital transfers by SOURCE vital, so family 89 holds both
"Stamina to Health" and "Stamina to Mana". Picking the strongest tier in a
family would convert into the wrong vital about half the time. Buff lines
group by family (correct for duration buffs, which is retail's own stacking
bucket); the conversions are found by name stem instead.
* Instantaneous spells have no duration and must be excluded from buff lines
entirely, or they are treated as buffs that never appear to land.
Tier selection now follows the character's skill in the casting school against
the spell's difficulty (VTank's SpellDiffExcessThreshold-Buff), which is why
PluginSpellInfo gained School as a SKILL id -- MagicSchool is retail's 1-5
school enum, not something a character trains.
Mana upkeep is the loop asked for: convert stamina to mana when mana is low,
Revitalize when that leaves stamina too low to convert, and refuse to drain
stamina past a floor. Unknown vitals read as zero and are treated as "no
information" rather than "empty", so it will not cast on a healthy character.
Panel no longer shows at character select. IsAvailable is now the runtime's
own lifecycle state rather than a proxy, and markup gained visible="{Binding}"
plus UiElement.VisibleSource -- evaluated before the visible gate, because
TickSelfAndChildren returns early when hidden and an element could otherwise
never un-hide itself.
Also: a generated SpellId enum of all 6,266 spells (tools/SpellDump --enum),
generated from portal.dat rather than copied, so it cannot drift and carries
no third-party licence; skill and spell names now come from the retail tables
for display; and the Buff click logs unconditionally, so "nothing happened"
can be told apart from "the click never arrived".
Solution builds clean; 14,433 tests pass on the standard hermetic lane filter,
0 failures, including 21 covering the buff profile, tier selection and mana
loop.

First consumer of acdream's plugin automation surface, and the first slice of
the VTank-class plugin milestone
(docs/research/2026-07-29-vtank-plugin-automation-requirements.md).
MossTank shows a panel with a Buff button; clicking it casts every self-buff
the character is missing, skips what is already in force at an equal or higher
tier, and refreshes what is nearly expired.
The host/plugin line is the load-bearing decision here. The host publishes
spell DATA -- family, tier, difficulty, mana, duration -- plus a cast
primitive with a preflight gate. The plugin owns the POLICY. That is the
architectural conclusion the requirements research reached: VTank's engine
lived in plugin-land, built on Decal's primitives, and baking "best buff for
skill X" into the host would start pulling the engine inward one convenience
at a time.
Why the plan is driven off the spellbook rather than off trained skills, which
is the obvious reading of "buff every trained and specialised skill": the
client cannot honestly make that mapping. The link between a spell and the
stat it modifies arrives from the SERVER in the enchantment message and is
absent from the client's own spell table. What the client does know is which
spells the character has learned -- and a character only learns buffs for the
skills they use, so the spellbook reaches the same set without inventing a
mapping the client has no grounds for.
Surface added, all BCL-only so Plugin.Abstractions keeps its zero project
references:
* ICharacterInfo, ISpellCatalog, IMagicCommands, grouped behind one
IAutomationSurface so IPluginHost grows by one member rather than three.
* IEvents.Tick. Automation is sequences, not single calls -- a buff pass casts
several spells and must wait between them. Without a host tick a plugin
would need its own timer thread re-entering the host off its update thread.
* NoOpAutomationSurface for hosts with no live session, so a plugin keeps one
code path and checks IsAvailable.
Markup gained <button> and <label>; it previously supported only <meter>, with
a comment promising the rest. Buttons bind onclick to an Action property and
FAIL THE PANEL LOAD if it does not resolve -- a silently dead button is worse
than a panel that refuses to load, because the user clicks and there is
nothing to diagnose. Labels bind through a Func so a status line tracks its
binding instead of freezing at build time.
Enchantment reads use EnchantmentsInEffectSnapshot rather than the raw active
set: retail leaves a weaker same-family enchantment in the registry while a
stronger one is in force, and a plugin asking "am I buffed?" means in force.
BuffPlan is a pure function of (known buffs, active enchantments) precisely so
it can be tested without a session; 9 tests cover tier supersede, the
family-0 no-stack bucket that must not be de-duplicated, expiry refresh, and
plan stability across the rebuilds the tick loop performs.
Solution builds clean; 14,421 tests pass on the standard hermetic lane filter,
0 failures.
