## Engram (Mandatory)

start: mem_context
decisions: mem_save (type: decision/architecture)
end: mem_session_summary

Store only: architectural decisions, pattern choices, trade-offs, constraints.
Never store: code, diffs, ephemeral reasoning.

## Modes

active: standard
- performance-strict → @perf+ | O(n) always | hot-paths
- high-reliability   → @rel+  | err-explicit | invariants
