# Session Log – zlh-grind

Append-only execution log for GPT working in ZeroLagHub environment.

- Goal: Stabilize zlh-agent provisioning pipeline for game + dev containers + addons without regressing game provisioning.
- Scope: Agent routing (ctype=dev), local artifacts strategy, addon skeleton, initial end-to-end tests.
- Adopted single base template approach (zlh-agent template) where agent installs roles at runtime.

## 2025-12-20
- Goal: Restore reliable end-to-end provisioning for **game + dev** without regressions; preserve the explicit orchestration steps/logging.

### Current Architecture Reality (IMPORTANT)
- We are on **single base template**: `AGENT_TEMPLATE_VMID` is the only template in `.env`.
- In this workflow, **any zlh-agent code change requires rebuilding + pushing the binary into the template container**.
  - That effectively means: **agent change = new template promotion**.

### Key Findings / Fixes
- Game provisioning steps are functioning again and show clear step-by-step orchestration output (allocate VMID → clone → configure → start → IP → agent config → wait → DB save → edge publish).
- Dev provisioning failure was traced to a **wire contract mismatch** between API JSON and agent `state.Config` struct tags:
  - Agent expects: `container_type` (snake_case) on the JSON wire
  - API refactors were sending: `ctype` / `containerType` (camelCase) in some variants
  - Result: `cfg.ContainerType == ""` on decode → agent routes into game path → errors like:
    - `unsupported container identity (containerType="" game="")`

### Decision (to minimize churn)
- Because agent changes force a template promotion in this pipeline, the correct short-term move is:
  - **Update API to emit `container_type`** to match the existing agent contract
  - Avoid touching agent code until we intentionally rev the template

### Operational Guardrails
- Do NOT remove or "simplify" the explicit provisioning steps/logging; they are required for debugging and operator confidence.
- Treat `container_type` as the canonical wire key until the next planned template rev.
