By name: streaming-and-execution description: Incremental/streaming computation and query execution — DBSP, dataflow, windows, operators, deterministic replay.
streaming and execution
Category skill (blueprint pack). The description above is the only thing the
router sees — broad and generic on purpose. The fat detail lives in the
blueprints below; open the one that matches and read it in full.
Governs its own form per .claude/rules/rules-are-small-carved-sentences-pointing-to-docs.md
and .claude/rules/mirror-beacon-register-discipline.md (carved sentence = hub /
Beacon; blueprint = satellite / Mirror). The directory is an independent shipping unit.
