Hardpoint Guardian Design Decisions

The comprehensive analysis of hp-guard's design has been split into 7 focused articles, each covering a specific aspect of the policy engine:

Article Focus
Dual-Runtime Philosophy No reference implementation; conformance drives correctness
Constrained YAML Language Ambiguous scalars rejected; bounded condition surface
Explicit Audit JSON Lines format; deliberate audit boundaries
v2 Rate Limits Process-local fixed-window only; no persistence
Inline Adapter Validate + decide + log + return effect; host executes
Simulator Replay traces without execution or side effects
Time Windows Local UTC wall clock; no clock skew compensation
