glm-5.1 5c820a41e9 tasks: decompose Phase 0a ADR foundation and mark prior tasks completed
Add 10 new tasks under tasks/architecture/ for Phase 0a (ADR writing):
- 9 ADR tasks (026-034) with dependency-ordered structure
- 1 review checkpoint task before Phase 0b spec writing

ADR dependency graph (3 generations):
  Gen 1 (parallel): 026, 029, 030, 031, 032, 034
  Gen 2 (depends on 029): 027, 028
  Gen 3 (depends on 027+028): 033
  Gen 4: review checkpoint

Also mark all 34 prior implementation tasks as completed — they
were finished but still showing as pending in the taskgraph.

architecture/adr-030-static-dynamic-config-split Write ADR-030 — Static/dynamic config split pending
narrow low phase implementation

Description

Write ADR-030 establishing the split between StaticConfig (immutable after startup) and DynamicConfig (hot-reloadable at runtime) in alknet-core.

This is largely a promotion from the well-analyzed research in docs/research/configuration.md. The ADR records why this split matters, what goes in each config, and how reload works.

Key points:

  • StaticConfig: transport mode, listen addr, TLS config, iroh config, host key, stealth mode, max auth attempts, max connections per IP — everything that requires socket/TLS renegotation to change
  • DynamicConfig: auth policy (authorized keys, cert authorities), forwarding policy, rate limits — everything checked per-connection or per-channel
  • ArcSwap for lock-free hot reload of DynamicConfig
  • ServeOptions builder pattern is preserved; StaticConfig is constructed from ServeOptions
  • TOML config file is an optional convenience input format (amends ADR-011, doesn't replace programmatic API)
  • ConfigReloadHandle with reload(DynamicConfig) method
  • NAPI exposes reloadAuth(), reloadForwarding(), reloadAll() on AlknetServer

Acceptance Criteria

  • docs/architecture/decisions/030-static-dynamic-config-split.md exists
  • ADR follows established format
  • Context explains the three failures: no hot reload of auth, no forwarding policy, no structured config beyond CLI flags
  • Decision states: StaticConfig vs DynamicConfig split; ArcSwap for DynamicConfig; ServeOptions preserved as builder; TOML as optional convenience; ConfigService wraps reloads; amends ADR-011
  • Lists what's in StaticConfig and what's in DynamicConfig
  • Consequences: auth and forwarding can be reloaded without restart; config file users get TOML format; programmatic-first API preserved
  • References: research/configuration.md, ADR-011

References

  • docs/research/configuration.md — full analysis, nearly spec-ready
  • docs/architecture/decisions/011-no-ssh-config-programmatic-api.md — programmatic-first decision (amended, not superseded)
