glm-5.1 2b63cda1c7 Setup repo: migrate architecture specs, code stubs, and tasks from alkhub_ts
Copy architecture docs, ADRs, storage domain specs, research, reviews,
and 56 storage architecture tasks from the alkhub_ts monorepo. Adapt for
standalone @alkdev/hub repo structure (src/ not packages/hub/).

Sanitize all sensitive information:
- Replace private IPs (10.0.0.1) with localhost defaults
- Remove internal server hostnames (dev1, ns528096)
- Replace /workspace/ private paths with npm package references
- Remove hardcoded credentials from examples
- Rewrite infrastructure.md without private network details

Add Deno project scaffolding: deno.json (pinned deps), .gitignore,
AGENTS.md, entry point. Migrate existing code stubs (crypto, config
types, logger) with updated import paths.

define-call-graph-retention Define Call Graph Retention Policy completed
narrow low component implementation

Description

W09: Call graph data grows unboundedly — every operation invocation creates a node and edges. CASCADE handles cleanup on node deletion, but nothing deletes old nodes. README.md acknowledges this as Open Question #5 but no approach is specified.

Specify the intended approach: TTL-based deletion, archival to cold storage, or aggregation + deletion. Even a phased notation ("v1: manual cleanup, v2: automatic TTL") helps implementers understand the plan.

Acceptance Criteria

  • call-graph.md includes a "Retention Policy" section
  • Short-term approach specified (e.g., manual cleanup or no cleanup for v1)
  • Long-term approach outlined (e.g., TTL-based, aggregation + deletion)
  • README.md Open Question #5 resolved with cross-reference to call-graph.md section
