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.

Description

W18: The truncation strategy says "truncate payloads larger than 10KB" but doesn't specify: when truncation happens (on write? after call completes?), what preview contains (first N bytes? N characters?), whether 10KB is configurable, or how object storage reference URLs are structured.

Specify: (a) truncation happens on write to DB (in-flight calls have full payloads); (b) preview is the first 1024 bytes of the JSON-serialized payload; (c) threshold is configurable per operation type or via hub config; (d) defer object storage details but add a placeholder section.

Acceptance Criteria

  • call-graph.md specifies truncation timing: on DB write, not in-flight
  • preview field defined: first 1024 bytes of JSON-serialized payload
  • 10KB threshold documented as configurable (hub config or per-operation-type)
  • Placeholder section for object storage reference (deferred)
  • Cross-reference to redaction strategy (this task depends on W08 resolution)
