glm-5.1 19b3d3a078 docs: write Phase 0 architecture foundation — ADRs 026-034, spec docs, and task updates
Phase 0a — ADRs (9 new):
- ADR-026: Transport/interface separation (three-layer model)
- ADR-027: Crate decomposition (core, secret, storage, flowgraph, napi, CLI)
- ADR-028: Auth as irpc service (AuthProtocol behind feature flag)
- ADR-029: Identity as core type (Identity + IdentityProvider in alknet-core)
- ADR-030: Static/dynamic config split (ArcSwap, ConfigReloadHandle)
- ADR-031: Forwarding policy (rule-based allow/deny, TransportKind-aware)
- ADR-032: Event boundary discipline (domain, irpc, call protocol boundaries)
- ADR-033: OperationEnv universal composition (three dispatch paths)
- ADR-034: Head/worker terminology (replace hub/spoke)

Phase 0b — New spec documents (7):
- identity.md, services.md, interface.md, configuration.md,
  storage.md, flowgraph.md, secret-service.md

Updated existing docs:
- auth.md: reference identity.md for canonical definitions, add AuthProtocol
- open-questions.md: resolve OQ-12, OQ-16, OQ-18, OQ-22, OQ-23-25
- README.md: add all new docs, ADRs 026-034

Marked 19 architecture tasks as completed.

Description

Create docs/architecture/flowgraph.md — an architecture spec for the alknet-flowgraph crate, covering FlowGraph<N,E>, operation graph construction, call graph population, and type compatibility checking.

Like storage.md, this can be a contract-level document if the crate will have its own docs later. The key contract point: OperationSpec and CallNodeAttrs types must match alknet-core's definitions, with serialization as the bridge.

Source: docs/research/flow.md (472 lines, straightforward port of TypeScript design)

This is the lowest-risk new spec — pure computation crate, no I/O, no external state, straightforward petgraph port.

Acceptance Criteria

  • docs/architecture/flowgraph.md exists with YAML frontmatter (status: draft)
  • Follows spec format: What, Why, Architecture, Constraints, Open Questions, Design Decisions
  • Documents FlowGraph<N, E> generic graph over petgraph::DiGraph
  • Documents NodeAttributes / EdgeAttributes traits
  • Documents operation graph construction from OperationSpecs
  • Documents call graph population from EventEnvelope events
  • Documents type compatibility checking (jsonschema)
  • Documents cycle detection, topological sort, reachability queries
  • Documents serde serialization/deserialization
  • States crate dependencies: petgraph, serde, serde_json, jsonschema, thiserror
  • States crate does NOT depend on alknet-core, alknet-storage, or alknet-secret
  • States interface back to core: OperationSpec and CallNodeAttrs types match alknet-core's definitions; bridge is serialization
  • References ADR-027
  • docs/architecture/README.md updated to include flowgraph.md
