patterns

Overview ¶

Package patterns implements learning pipeline D: an offline cross-branch pattern index. The learn worker compares each configured repo's branch tips against persisted state (milliseconds of git, zero LLM); only branches whose tips moved are re-mined — commit clusters become work units, one cheap call per branch turns them into repo-scoped pattern cards whose bodies carry representative diff hunks (the payload that makes "apply this pattern" work at retrieval time). Deleted branches retire their cards unless the work was merged.
