# Knowledge And Skill Foundation

Version `0.1.R` defines how Agrarian treats knowledge, practice, body condition,
tools, and infrastructure before those systems become heavy gameplay code.

## MVP Separation Model

Agrarian should not collapse every form of progress into one generic skill
number. The MVP separates five related but distinct drivers.

Knowledge:

- Represents what a character understands.
- Comes from observation, teaching, notes, mistakes, questions, and practice
  reflection.
- Affects judgment, recognition, safety, sequencing, and when warnings appear.
- Should help players understand why something worked or failed.

Practical experience:

- Represents practiced execution under real conditions.
- Comes from repeated action, variation, failed attempts, recovery, and doing
  the work in different weather, light, terrain, and tool conditions.
- Affects speed, consistency, yield, precision, and waste.
- Should grow slowly from use and should not replace core understanding.

Physical stats:

- Represent the body in the moment: health, stamina, hunger, thirst, body
  temperature, exhaustion, injury, sickness, age, carry load, and care history.
- Affect what a character can safely do right now.
- Should create readable pressure without becoming a hidden knowledge system.

Tools:

- Represent external capability the player can hold, equip, place, or maintain.
- Affect what actions are possible, how safe they are, how much effort they
  require, and how good the result can be.
- Should still require knowledge and practice for best outcomes.

Infrastructure:

- Represents durable world improvements such as shelter, storage, paths, wells,
  fields, workshops, firebreaks, and community systems.
- Affects baseline safety, efficiency, capacity, and resilience.
- Should reduce routine survival pressure without removing consequences from
  poor choices.

MVP rule: basic survival actions must remain possible with low knowledge and
poor tools, but outcomes should be riskier, slower, lower quality, or more
wasteful until knowledge, practice, tools, and infrastructure improve.

## First-Pass Skill Taxonomy

The MVP skill taxonomy starts with practical survival domains the player uses in
the first hours of play. Each skill can later contain knowledge topics,
practice records, tool modifiers, environmental modifiers, and teaching hooks.

Survival:

- Core self-care, prioritization, risk recognition, rest, hydration, calories,
  warmth, and avoiding preventable injury.
- Early effects: better warning timing, fewer panic mistakes, and more reliable
  recovery choices.

Gathering:

- Identifying useful resources, harvesting safely, avoiding waste, and knowing
  when weather, light, terrain, or tool condition makes gathering risky.
- Early effects: better yield, lower injury risk, and less resource damage.

Tool use:

- Handling primitive tools safely, choosing the right tool, maintaining tools,
  and recognizing when improvised use is dangerous.
- Early effects: less stamina cost, fewer injuries, and more consistent work.

Crafting:

- Following recipes, sequencing steps, judging material suitability, and
  recognizing weak or unsafe results.
- Early effects: fewer failed crafts, less waste, and better item quality.

Fire:

- Ignition, fuel choice, containment, maintenance, extinguishing, smoke, warmth,
  wildfire risk, and using fire without burning structures or vegetation.
- Early effects: safer campfires, lower spread risk, and better warmth/cooking
  reliability.

Shelter:

- Site choice, wind/rain exposure, drainage, structural basics, maintenance,
  insulation, and avoiding fire or flood hazards.
- Early effects: better placement, more reliable protection, and fewer wasted
  materials.

Navigation:

- Reading terrain, weather, daylight, landmarks, slope, watercourses, and safe
  routes.
- Early effects: fewer dangerous detours, better route choice, and safer return
  to shelter.

First aid:

- Recognizing injury, bleeding, sprains, sickness, cold exposure, dehydration,
  and when rest or treatment matters.
- Early effects: earlier warnings, better treatment choices, and reduced
  recovery mistakes.

Food safety:

- Potable water, edible plant caution, spoilage awareness, cooking basics,
  contamination risk, and unsafe hunger-driven decisions.
- Early effects: fewer sickness triggers and better food/water decisions.

Weather awareness:

- Reading temperature, wind, rain, exposure, nightfall, storms, and shelter/fire
  implications.
- Early effects: earlier shelter/fire decisions and fewer exposure surprises.

Taxonomy rule: skills are not unlock gates for basic MVP survival actions. They
modify risk, quality, speed, yield, readability, and confidence.
