Limit

What it actually is

A boundary that either defines the shape of something, or exposes the shape of whoever is running into it.

How it works

A limit activates when a system, person, or process approaches a value it cannot exceed without changing its fundamental nature. There are two modes:

Hard limits: The system stops. The bone breaks. The budget hits zero. No negotiation.

Soft limits: The system continues, but degrades. Output quality drops. patience drains. The thing is technically still running but nobody should trust it.

In mathematics, a limit is cleaner: the value a function approaches as the input gets arbitrarily close to some point. It never arrives. It just gets close enough to matter. This is also how most people experience their own potential.

Features

Enforces structure on otherwise formless systems
Creates scarcity, which creates value, which creates entire economies
Reveals character. What a thing does at its limit is what it actually is
Available in: time, space, energy, memory, love, rope, patience, cellular data
Self-reporting: most limits announce themselves through discomfort before failure

Known bugs

Users frequently mistake cultural limits for physical ones, and vice versa
ego causes systematic underestimation of personal limits until approximately 72 hours too late
Some limits are set so low they function more like pessimism than physics
Limits on other people are almost always misconfigured by the person observing them
Occasionally a limit believed to be hard turns out to be soft. This is called a breakthrough, or an injury, depending on the domain

Configuration

limit:
  type: hard | soft | perceived | imposed | self-selected
  source: biology | society | physics | habit | someone-else's-opinion
  visibility: visible | hidden | discovered-the-hard-way
  negotiable: rarely
  retry_after: depends

Error codes

Code	Message	Likely cause
`LIM_001`	Threshold exceeded	Tried to pour more than capacity allows
`LIM_002`	Approaching limit	Normal. Slow down or commit.
`LIM_003`	Limit not found	Either you have no limits or you haven't looked hard enough
`LIM_004`	Limit set by external process	Not yours to configure
`LIM_SELF`	User-imposed constraint	Possibly load-bearing. Do not remove without inspection

Edge cases

A system with no limits is not free. It is undefined.
Children do not ship with preconfigured limits. These are installed gradually by consequence.
In calculus, a limit can exist even when the function does not reach it. Philosophers have been using this as a metaphor for approximately 300 years.
Two people can approach the same limit from opposite directions and arrive at completely different conclusions about whether it exists.

FAQ

Q: Can limits be expanded? A: Some. The ones worth expanding usually resist at first.

Q: Should I push mine? A: The spec does not make recommendations. It only documents behavior.

Q: What lives on the other side of a limit? A: Either growth, or a different kind of limit. Sometimes both.
