# Session Log – zlh-grind

Append-only execution log for GPT work.

## 2025-12-13
- Goal: Establish `zlh-grind` as the execution ledger and drift firewall.
- Scope: Repo scaffolding + constraints + session templates.
- Explicit non-goals: Any architecture or canonical docs changes.
- Canonical refs used: `jester/knowledge-base` (Drift card, tracker, GPT handover).

Work completed:
- Verified Gitea MCP connectivity (server version 0.5.0+2-g8b06d71).
- Confirmed `jester/zlh-grind` exists.
- Added repo-level drift controls:
  - `CONSTRAINTS.md`
  - `SESSION_START.md`
  - `OPEN_THREADS.md`
  - `SESSION_LOG.md`
- Added explicit guardrail doc: `ANTI_DRIFT.md`.
- Stabilized MCP routing and validated the Knowledge tool is working reliably.
- Tagged `jester/zlh-agent` with annotated tag `v0.1.0-dev`.
- Added `UPSTREAMS.md` to register canonical + execution repos and the Go agent repo.

Notes:
- MCP write operations are now functional from this environment.
