regret

What it actually is

The experience of computing a better past and having nowhere to put the output.

How it works

An event concludes.
memory encodes the outcome with higher fidelity than the decision that caused it.
The brain runs counterfactual thinking: a simulation of the road not taken, rendered in suspiciously flattering detail.
The gap between simulated outcome and actual outcome is measured.
The gap is assigned to the self as fault.
Repeat indefinitely.

The process is automatic. There is no opt-out flag. Suppression attempts typically increase loop frequency.

Features

Temporal flexibility: operates on events from 30 seconds ago to 47 years ago with equal enthusiasm
Selective rendering: the alternative timeline is always cleaner than the one you lived
Social mirroring: intensifies when other people appear to have chosen correctly
Nocturnal mode: activates at 3am without user prompt
Compound interest: small regrets accrue quietly until they are not small

Known bugs

Bug	Frequency	Status
Certainty that you knew better at the time	Universal	Won't fix
Mistaking regret for guilt	Common	By design
Retroactive clarity about what mattered	Chronic	Cannot reproduce in forward time
Regretting the regret	Rare (then common)	Open
Conflating "I should have" with "I could have"	Very common	Upstream issue

Configuration

# regret.config.yml
intensity: auto          # scales with perceived stakes; not user-adjustable
target: self             # occasionally misdirected to others (see: resentment)
duration: indefinite     # set to "brief" in documentation; ignored at runtime
trigger_on_idle: true    # cannot be set to false
compare_to: best_case_scenario  # hardcoded; median_case not available

Error codes

ERR_404  : The life you meant to live was not found
ERR_301  : Permanently redirected from who you were going to be
ERR_409  : Conflict between who you are and who you told yourself you were
WARN_001 : Memory is reconstructive; this simulation may not reflect actual conditions

Edge cases

No regret: Either very healthy or a known sociopathy symptom. Diagnostics inconclusive.
Regret about nothing specific: See existential dread. Different module, shared infrastructure.
Regret expressed immediately: Usually called an apology. Different spec, overlapping codebase.
Regret as motivation: Documented but unreliable. Side effects include overcompensation and anxiety.

FAQ

Does it get easier? The literature says yes. The module does not appear to have read the literature.

Is it useful? In small doses: yes. It encodes lessons. In large doses: it encodes identity.

Can I turn it off? Alcohol, sleep deprivation, and dissociation each reduce signal temporarily. All three introduce their own regrets downstream.

Should I regret reading this? That is now, technically, your problem.
