zlh-grind/README.md

zlh-grind

Execution workspace for ZeroLagHub (ZLH).

This repo is intentionally lightweight and is used for:

• handovers / "where we left off" notes
• architecture decisions + rationale
• config snippets worth preserving
• TODO lists that don't belong in a code repo

Latest handover (2026-02-07)

• SCRATCH/2026-02-07_customer-id-schema.md

  • Why a newly registered user looked "hashed" (it's Prisma cuid()),
  • Why ContainerInstance.customerId got polluted with u-dev-001,
  • The chosen short-term rule: use req.user.id everywhere.

• SCRATCH/2026-02-07_prometheus-grafana.md

  • Prometheus HTTP service discovery via API /sd/exporters,
  • Grafana dashboard import gotchas + the "CPU doesn't match top" note,
  • Next steps to power portal server cards with metrics.

• SCRATCH/2026-02-07_host-controls-and-delete-failsafe.md

  • Decision: keep delete failsafe, add host controls.

Scratchpad

SCRATCH/ contains one-off notes that may later be promoted into formal docs.
