# Migration rehearsal — reichelag sample (2026-08-13)

| Field | Value |
|-------|--------|
| Workplan | CSOC-WP-0001-T04 |
| Depends on | CSOC-WP-0006 PageOps landing pad |
| Source (local only) | `~/.config/coulomb-social/auth/exports/corpus-202608131015057/trees/reichelag/` |
| Destination | `CONTENT_ROOT/spaces/reichelag/` (local; not committed) |
| Command | `manage.py import_content_tree` |

**Do not commit** source trees or imported content — private business notes.

## Command

```bash
export CONTENT_ROOT="$PWD/var/content-rehearsal"   # or default var/content
uv run python manage.py migrate
# sign-in once or ensure a Member exists for --member-subject
uv run python manage.py import_content_tree \
  ~/.config/coulomb-social/auth/exports/corpus-202608131015057/trees/reichelag \
  --tenant tenant:coulomb \
  --member-subject <your-oidc-subject> \
  --replace
```

Dry-run:

```bash
uv run python manage.py import_content_tree PATH/TO/tree --dry-run
```

## Result (this run)

| Metric | Value |
|--------|------:|
| Pages copied | 30 (1 index + 29 articles) |
| Assets copied | 29 (logo/visual images) |
| Space row | Created `reichelag` title **ReichelAG** |
| Render path | `load_space_page` → `source=content-plane` |
| Index title | ReichelAG |
| Sample page | frontmatter title + markdown body render OK |
| Visual files | Present under `assets/` for pages that declare them |

## Lossiness and residuals

| Gap | Severity | Note |
|-----|----------|------|
| Bubble `Slug` vs export slug | low | Bubble space slug was `new-space-36`; export/tree uses friendly `reichelag` |
| Space display title | medium | Not first-class on `custom.space`; taken from index frontmatter / guess |
| Membership list | medium | Only local owner from `--member-subject`; Bubble `members_list_user` not mapped to NetKingdom |
| Parent/article graph | medium | Frontmatter `parent` kept as opaque bubble id; no outline/include graph yet |
| Full corpus coverage | high | Only **one** dense sample tree; 70 other spaces not imported; many spaces have incomplete article dumps |
| Chunk / Research UI | deferred | Bubble `pg_chunk` / Research surfaces not in tree |
| Workflows / privacy flags | deferred | `isprivate_boolean` not enforced in rebuild authz beyond tenant membership |
| Identity | blocked elsewhere | Member transfer assist / public registration (CSOC-IN-0001) |
| Production path | deferred | Rehearsal is local `CONTENT_ROOT`; cluster import needs operator CONTENT_ROOT volume + tenant choice |

## What worked losslessly (for this tree)

- Page **Title / Abstractor / Visual** frontmatter → PageOps + Space index fields  
- Markdown **body** → content-plane render (bleach markdown pipeline)  
- Relative **visual** assets under `assets/`  
- **Page list** via `list_pages`  
- Idempotent re-import with `--replace`

## Acceptance against CSOC-WP-0001

- [x] At least one migration rehearsal run  
- [x] Residual gaps listed (above)  
- [ ] Bulk multi-space import + NK membership map — residual  
- [ ] Apex cutover — still gated on product parity + self-registration
