+# Plan: dist publish + dist.mize.works (approved)
+
+## Config
+- `parts.workspaces`: list of dirs; each subdir is a part to build/upload
+- `parts.dist.cd`: bool; when true artifact uses `-cd` instead of `-{version}`
+
+## Publish (`mize.dev`)
+- After build: pack each part `.so` under `lib/`, special part `mize` gets `libmize.so` + `bin/mize`
+- Hash via `get_part_hash` with modName, system (target), mize_version
+- Filename: `{hash}-{id}-{version}.tar.gz` or `{hash}-{id}-cd.tar.gz`
+- rsync to `ocib:host/mize-dist/`
+
+## fetch_part
+- Base URL `https://dist.mize.works/`
+- Same naming; ensure mize_version in selector
+
+## ocib
+- `~/host/docker-compose.yaml`: Traefik + kugland/darkhttpd serving `mize-dist` for `dist.mize.works`

+# load_part_at instances (priv.spacetime / ppc.spacetime)
+
+Approved 2026-11-04.
+
+## Goal
+Instantiate the same `spacetime` `.so` under different part ids (`priv.spacetime`, `ppc.spacetime`), each with its own config namespace. Dependents use `Spacetime::get("priv.spacetime")` etc.
+
+## Changes
+1. Platform `load_part(part_name, path, at_id)` via `get_global_mize()`; save/restore `cur_eval_part`.
+2. Rename `Mize::load_part_at` → `load_part_from_path`.
+3. `config::load_part_at(at_id, part_name)` — no-op in generate mode.
+4. Codegen: special SpacetimeDB client gen when `gen` contains `"spacetime"`, module at `{cwd}/spacetime` if present.
+5. `sci`: `gen += spacetime`, `load_part_at("priv.spacetime", "spacetime")`.
+6. New `mize/parts/ppc`: loads `ppc.spacetime`.
