Patterns-Borrowed-Not-Understood Thesis

Description

Community consensus from the 20-day retrospective: Claude Code's architectural patterns (fork-subagent, sidechain transcripts, deny-first layered permissions, five-layer compaction) are being widely replicated in derivative agents, but without the design reasoning behind them. Implementations tend to get the surface pattern right and the invariants wrong — e.g., copying fork-subagent without preserving the summary-only return invariant, or copying deny-first without the precedence rules.
