Changelog • dagriculture

dagriculture 0.1.6

Error message consistency: dagri_validate_node_ids(), dagri_validate_external_holds(), and dagri_pending_gates() now use sprintf to embed missing IDs in error messages, matching the pattern used by all other not-found errors.
Package metadata: added explicit Author and Maintainer fields to DESCRIPTION for bare R CMD check compatibility alongside the existing Authors@R field.
Build ignore cleanup: added .desloppify, .factory, .Rcheck, and ..Rcheck to .Rbuildignore.

param_schema validation: dagri_kind() now validates that param_schema is a named list or NULL before scanning it for closures, rejecting non-lists and unnamed inputs early.
DFS re-validation: dagri_dfs() and dagri_topo_order() no longer re-validate the graph on every iteration, improving performance for large reachability queries.
Subset validation in dagri_topo_order(): the subset argument is now validated and de-duplicated via dagri_validate_node_ids() before building the topological sort.
Documentation: fixed edge_id parameter name to edge in dagri_add_gate() calls in README and doc vignette. Expanded dagri_validate_graph() description to document full validation scope.

Graph validation: all public functions now validate that the graph argument has the required structure (dagri_validate_graph()), producing a clear error instead of cryptic R failures on malformed input.
Input contract enforcement: dagri_kind() validates that input_contract is a named list with character or NULL values. dagri_add_node() checks that node params satisfy the kind’s input_contract at creation time.

CI and structural helper linting: fixed .lintr snapshot exclusions for current lintr, documented dagri_target_closure() and dagri_pending_gates(), updated dagri_terminal() docs for scoped targets, and shortened structural test fixture names to satisfy CI lint checks.

Node deletion cleanup: dagri_remove_node() now removes incident edges and any gates attached to those edges, preventing dangling references after structural deletes.

Planner-visible external holds: dagri_plan() now accepts caller-supplied external_holds, preserves structural eligible semantics, and returns propagated non-structural holds in external_blocked without mutating the graph.

Constructors: Functions to create and define kinds, registries, and the core graph structure (dagri_kind(), dagri_registry(), dagri_graph()).
Graph Editing: Implemented structural modifiers to add/remove/update nodes, edges, and explicit blockers called gates.
Topology Queries: Topological sorting and traversal utilities (ancestors, descendants, upstream, downstream, roots, leaves, reachability).
Structural Planning: Determine node eligibility and blocked reasons through declarative resolution without side-effects or executing runtime jobs (dagri_recompute_state(), dagri_plan()).

All structures fully align with the plain-data spec and are serialized purely as nested named lists (JSON compatible).
Defined explicit typed errors in abort_dagri().
Removed hello() template code.
