What shipped, and why it mattered.

# <feature>: PRD lite

**Problem**: what's broken, for whom, and why now.
**Users / context**: who hits this, how often, in what situation.
**Goal**: the one outcome that means success.
**Out of scope**: what we are deliberately NOT doing.
**Approach**: the shape of the solution (a level up from implementation).
**Success metric**: how we'll know, stated before we build.
**Risks / unknowns**: what could make this wrong.
**Rollout**: how it ships, and how it rolls back.

# <decision>: ADR

**Status**: proposed | accepted | superseded
**Context**: the forces in play; what makes this a real choice.
**Options considered**: each with its honest tradeoffs.
**Decision**: what we chose.
**Rationale**: why this beat the alternatives.

# <experiment>: note

**Hypothesis**: we believe X will cause Y, because Z.
**Method**: what we ran, on whom/what, how controlled.
**Measured**: the metric(s), defined up front.
**Result**: what actually happened (including "nothing").
**Decision**: ship / iterate / drop, and why.
