What alignment is this dungeon?

So for those anti alignment fans this wont bring you joy. This is quick way of exploring the otherworldly taint of every dungeon. It provides a quick way to differentiate dungeons or parts of them. Some dungeons are sentient or influenced by plains or at least have a leader with an alignment.

A dungeon might be built for one purpose and be repurposed by another. This could have happened in past or be in middle of happening.

I have detect alignment abilities pretty common. A good room in a monster hellhole is possible or remains of good, defiled by evil possible.

Alignment on the law-chaos axis is a measure of how a dungeon is organised.

A lawful dungeon has:
A sensible ecology
Toilets and food supply
Map makes sense
Things have a function
Follows principles of design and engineering
Internally consistent and logical
Things placed deliberately by reason
Grows on principles of cause and effect
Monsters restock over time from processes and cycles
Intelligent deliberate design
Well maintained and clean
Inhabitants behave in logical manner
Exploits and controls
Homoeostatic systems, patterns or cycles
Population tends to stabilise

eg
A fortified gatehouse at front of area
A store room full of food
Monster barracks
A faction calls other clan to repopulate area
Traps built to defend area or goods
Magical defence to defend treasure
A chest full of potions in a lab
A vault full of tax records
Sacred shrine of elaborate marriage rites

A chaotic dungeon has:
A random nonsense ecology
Basic needs of inhabitants ignored
Map might make no sense
Strange bewildering or pointless contents
Might break common laws of physics, geometry or engineering
Random and inconsistent
Things just appear and disappear at random
Spontaneous random growth
Restocks by magic
Mad or insane design
Run down with dug and graffiti
Inhabitants are insane and irrational
Confuses and mutates
Chaotic, unstable and fluid 
Population tends to boom and bust randomly

eg
A room randomly has a force of monsters with no idea why they are here
Random goods scattered around dungeon
A room full of orcs at end of corridor full of yellow mould
Monsters just appear at random to repopulate
Traps built randomly to be annoying more like pranks
Magical maze built by crazy wizard just because he could
A magical pool with random effects
A casino or gambling den with magic games
A room full of eggs covering every surface

A balanced dungeon might have:
Both lawful and chaotic features in harmony using best of both
Law and chaos in a struggle between factions in a war zone
Lawful beings trying to utilise a chaotic feature like guarding that magic pool
Chaotic beings ruining orderly structures like destroying doors or water supply
A ecology that includes chaotic features like monster jelly eating dung and corpses
May unite using best of both to fight intruders then return to conflict

Alignment on the good-evil axis is a measure of a dungeon ethical intention

A evil dungeon has:
Is equipped for sadism and cruelty
Have innocent prisoners in cells or torture chambers
Creating monsters from unwilling victims
Evidence of victims like blood, skulls, blood
Macabre trophies like pile of severed heads, bloody altars
Traps with delayed effects or that imperil trapped victims
Monsters bully each other in brutal manner
Evidence of defiled goodness
Screams, moans, evil cackles of bosses
Inhabitants are scarred, maimed and hungry
Inhabitants are angry, violent and mean spirited even to own
Dominates and abuses
Expansive, selfish and warlike
Population tends to aggressive

eg
A torture chamber with victims chained to a wall
A altar where undead created with pile of stolen defiled bodies
Monsters just torturing each other for fun
Monsters or villagers in chains hanging on walls
Trap that impales then drops scorpions onto face
Curse that turns victim into a beserker
Poisoned food or drink left out
Graffiti chamber full of faction tags and threats and sadistic murals
Training chamber with fighting pits and pits of corpses

A good dungeon has:
Is equipped for healing and self defence
Have evil creatures imprisoned and well cared for
Evidence of reformed evil doers confessions and atonement
Evidence of healing, good altars and noble self sacrifice for others
Artworks depicting good deeds and heroes bringing benefits to people
Traps which trap victim for later questioning
Guardians act in self defence, warn enemies and use fair play
Evidence of purged evil
Singing, chanting and prayers
Inhabitants are well cared for to best of leaders ability
Inhabitants are kindly, helpful and care for own kind and sometimes others
Helps and Protects
Defencive, harmonious and compassionate
Population tends to be peaceful

eg
A dispensary with quality food and drink
A altar where locals prey and perform healing
Locals discussing how to help each other with loving kindness
Well fed monsters or criminals in cells well cared for
Trap that drops cage over victim and rings alarm
Curse that turns victim into good
Healing potion left out trustfully for emergencies

A healers clinic helps anyone hurt no questions
A pleasant grotto or grove for contemplation and rest with food and drink

A middle dungeon might have:
Both good and evil features based on necessity
Good and evil in a struggle between factions in a war zone
Good beings trying to convert evil ones with kindness and love
Evil beings trying to taunt and enrage good beings into anger
A prison for possible reformed evil and a execution block for those deemed lost forever
May unite using best of both to fight intruders then return to conflict

Also consider...
So by now your thinking a good dungeon sounds totally lame and deserves to have monsters over run it. Which is a credible point. A good dungeon might be a base for good defending itself from evil. Perhaps wicked adventurers have come to steal poorly guarded healing potions. Perhaps they hire other alignments to do what they wont like kill prisoners they cant afford to keep and will do evil if released. Much like many religions hire other faiths to be butchers to avoid bad karma. Of course when war over, mercenaries might need to be paid to leave.

Lawful dungeons can be hacked by upsetting the systems or patterns or internal communications. A Chaotic one is more likely to depend on a relic or individual or magic to break it.

Sample Alignments Dungeon Types
Here are some tables to generate alignment features. Note the good ones are kind of struggling. A post on dungeon bosses and possible sentient dungeons will follow.

Obviously the dungeon ones below are to create stories where adventurers invaders mostly.
