hgraph Development

hgraph-compute-sink-node

Implement or review C++ hgraph compute nodes, sink nodes, algorithms, and concrete operator-node specializations. Use when adding or changing a static node `eval`, lifecycle hooks, local or recordable state, REF usage, incremental or windowed algorithms, input-type branching, operator strategy selection or overload registration, type-erased node strategy, node naming, complexity documentation, or native/Python behavioral tests for a compute or sink node.

hgraph-write-graphs

Implement or review composable C++ hgraph graphs and Python `@graph` functions. Use when adding or changing graph composition, wiring-time type or scalar decisions, graph overloads and polymorphism, `GlobalState` or `LOGGER` graph injection, conditional wiring, graph documentation, or native/Python graph behavior tests.

hgraph-write-operators

Define or review hgraph operator contracts and overload families in C++ and Python. Use when adding a C++ operator marker or Python `@operator`, replacing input-type or wiring-policy branches with overload selection, implementing node or graph overloads, registering C++ or Python candidates, designing defaults/resolvers/requires predicates, diagnosing overload ranking or ambiguity, generating the Python operator surface, or testing operator dispatch and cross-language parity.
