glm-5.1 466b121f77 decompose architecture into 38 atomic tasks across 12 parallel generations
Decompose the reviewed architecture specs into taskgraph-managed tasks:
- 2 setup tasks (project init, test infrastructure)
- 4 schema tasks (enums, node attrs, edge attrs, graph schemas)
- 1 error hierarchy task
- 6 graph tasks (FlowGraph class, 3 construction paths, queries, validation)
- 5 analysis tasks (type-compat, build-type-edges, ordering, template-validation, defaults)
- 5 component tasks (Operation, Sequential, Parallel, Conditional, Map)
- 2 host config tasks (GraphologyHostConfig, ReactiveHostConfig)
- 4 reactive tasks (WorkflowRoot, node-status, max-concurrency, retry-semantics)
- 3 review tasks (foundation, reactive-and-hosts, complete-library)
- 5 meta cluster tasks (schema, graph, component, reactive, analysis layers)
- 1 API exports task

Validated with taskgraph: zero cycles, 38 tasks, 12 parallel generations.
Critical path: 12 tasks through reactive execution layer.

Description

Implement the standalone analysis functions for execution ordering. These are pure functions operating on FlowGraph instances, delegating to graphology-dag algorithms.

Acceptance Criteria

  • topologicalOrder(graph: FlowGraph): string[] — uses graphology-dag topologicalSort, throws CycleError on cycles
  • parallelGroups(graph: FlowGraph): string[][] — groups by dependency depth (group 0 = roots, group 1 = dependents of group 0, etc.)
  • criticalPath(graph: FlowGraph): string[] — longest path through DAG
  • reachableFrom(graph: FlowGraph, nodeIds: string[]): Set<string> — BFS/DFS from starting nodes
  • ancestors(graph: FlowGraph, nodeId: string): string[] and descendants(graph: FlowGraph, nodeId: string): string[]
  • All functions are standalone (not FlowGraph methods), in src/analysis/
  • O(V + E) complexity for all — documented in JSDoc
  • Unit tests: known DAGs produce expected orderings, parallel groups, critical paths
