+# Stage 1 cutover — productive transfer set
+
+| Field | Value |
+|-------|--------|
+| Decision | [`../decisions/2026-08-12-feature-cut-stage-1.md`](../decisions/2026-08-12-feature-cut-stage-1.md) |
+| Model | [`model-v0.yaml`](model-v0.yaml) |
+| Date | 2026-08-12 |
+| Stance | **Partial rebuild is enough** for transfer; extend with later use cases after Bubble is reference-only |
+
+## Goal of stage 1
+
+Move members to **`app.coulomb.social`** as the **productive** home and retire
+Bubble on apex as a **productive** system. After transfer:
+
+- Bubble may remain online only as an **implementation reference** (read-only /
+  archival / comparison), not as the place where new work happens.
+- Additional capabilities (marketplace, social graph, monetization, …) ship
+  **later** on the rebuild without blocking transfer.
+
+## Must capabilities (stage 1)
+
+### 1. User onboarding — `cap.member-onboarding`
+
+Members can obtain and use an account on the rebuild without depending on
+Bubble for day-to-day login.
+
+| Feature | Status | Notes |
+|---------|--------|--------|
+| OIDC sign-in (existing LLDAP/KeyCape users) | shipped | Case A proven |
+| JIT Member + user-engine link | shipped | |
+| Session / account diagnostics | shipped | `/account/session/` |
+| Public Create account + verified mail | partial / blocked | App entry ready; NK mailbox (`CSOC-IN-0001`) |
+| Guided first landing on app home | shipped | post-login → Spaces |
+| Bulk / assisted member transfer from Bubble | todo | Process + optional import; no password migration |
+
+**Stage-1 acceptance:** known operators and community members can sign in;
+new members can register once NK path is live **or** operator-provisioned
+LLDAP accounts cover the transfer cohort. No Bubble password import.
+
+### 2. Spaces with markdown content — `cap.space-content`
+
+Members work in **spaces** whose durable content is **markdown** (ADR-0002).
+
+| Feature | Status | Notes |
+|---------|--------|--------|
+| Space list (tenant-scoped) | shipped | |
+| Space detail + render page from Forgejo | shipped | |
+| Edit in Forgejo + refresh / webhook | shipped | git SoR |
+| **Space CRUD** (create/read/update/delete or archive) | partial | Admin/seed today; **member UI CRUD todo** |
+| **Title** on space | partial | Model field exists; member edit UI todo |
+| **Abstract** on space | partial | Use `description` as abstract until renamed |
+| **Visual** on space (cover/image) | todo | Not in model yet |
+| Page list within space | partial | path-based pages; richer list todo |
+| **Page CRUD** (create/update/delete markdown pages) | partial | Via Forgejo only; in-app or first-class API todo |
+| **Title** on page | partial | From H1 / filename; structured frontmatter todo |
+| **Abstract** on page | todo | Frontmatter or metadata |
+| **Visual** on page | todo | Frontmatter image / assets |
+| Fail-closed missing binding | shipped | |
+
+**Stage-1 acceptance:** members can create and maintain spaces and pages with
+**Title, Abstract, Visual** as first-class fields (not only raw git for metadata),
+content body in markdown, readable on app host. Exact UX (in-app editor vs
+structured form + Forgejo body) can vary; **utility** must not require Bubble.
+
+### 3. Move page between spaces — `cap.page-transfer`
+
+| Feature | Status | Notes |
+|---------|--------|--------|
+| Transfer page to another space | todo | Move markdown (+ assets) + rewrite links; metadata follows |
+| Authz (source + destination membership) | todo | |
+
+**Stage-1 acceptance:** a page can leave space A and appear in space B without
+Bubble, with clear ownership after the move.
+
+### 4. Duplicate page — `cap.page-copy`
+
+| Feature | Status | Notes |
+|---------|--------|--------|
+| Generate copy of page (same or other space) | todo | New slug/title; independent thereafter |
+| Copy assets referenced by page | todo | Or document “copy body only” if scoped |
+
+**Stage-1 acceptance:** member can produce an independent copy without manual
+git surgery as the only path (operator git escape hatch may exist but is not
+the product path).
+
+## Explicitly later (not stage-1 blockers)
+
+Examples — full list in `model-v0.yaml`:
+
+- Favorites / social graph  
+- Marketplace (challenges, methods, solutions)  
+- Monetization / payments  
+- Full Bubble workflow automation parity  
+- Pixel-perfect Research chrome parity  
+- In-app collaborative real-time editing  
+
+## Platform dependencies (not product features)
+
+| Dependency | Stage-1 role |
+|------------|----------------|
+| NetKingdom OIDC + (eventually) registration mail | Onboarding |
+| apps-pg | Space/member metadata |
+| Forgejo | Markdown SoR |
+| Railiance deploy | Host app.coulomb.social |
+
+## Implementation backlog (derived)
+
+Priority order suggested for build work after this decision:
+
+1. Space member CRUD + Title / Abstract edit  
+2. Visual field (space, then page) + asset storage convention  
+3. Page metadata (title/abstract/visual) + create/update/delete path  
+4. Page copy  
+5. Page transfer  
+6. Onboarding: transfer cohort process + unstick public registration residual  
+
+Bubble export/mapping (CSOC-WP-0001-T02) feeds **content migration** into these
+capabilities but does not redefine the must set.
+
+## Open product questions
+
+1. **Visual** — cover image only, or gallery? Max size? Forgejo `assets/` vs object store?  
+2. **Abstract** — rename `Space.description` → abstract in UI only, or schema rename?  
+3. **Page body editing** — stage 1 keeps edit-in-Forgejo for body, app forms for Title/Abstract/Visual only? Or in-app markdown editor?  
+4. **Delete** — hard delete vs archive (`is_active`)?  
+5. **Transfer cohort** — require public self-registration, or LLDAP bulk invite for stage 1?

+# Capability / feature vocabulary (coulomb-social)
+
+Status: **adopted for product work** (2026-08-12)  
+Promote to fleet canon after one full cutover cycle.  
+Cites: orthogonal architecture Capability (C1–C3, `realizes`); reuse-surface
+for *cross-product* reuse only — not product feature flags.
+
+## The coin
+
+| Side | Name | Question |
+|------|------|----------|
+| **Utility** | **Capability** | What can a person *do* or *get*? Stable job-to-be-done. |
+| **Implementation** | **Feature** | Which concrete product slice delivers (part of) that utility? |
+
+Capabilities change slowly. Features appear, split, toggle, and retire under them.
+
+## Hierarchy (depth capped)
+
+```text
+Capability
+  └── Feature+          (implementation slices)
+        └── Realization (code, config, deploy)   — optional detail
+        └── Toggle?     (runtime/config switch on a feature or stage)
+```
+
+Rules:
+
+1. **Capabilities: few.** Target ~10–30 for all of coulomb.social, not hundreds.
+2. **No unlimited trees.** At most capability → optional sub-capability → feature.
+3. **One feature, one primary capability.** Cross-links allowed as `supports`, not multi-parent ownership.
+4. **Toggles attach to features (or release stages), never to capabilities.**  
+   “Turn off identity” is a product decision, not a flag.
+5. **Feature cut = prioritize capabilities**, then name which features are enough to call a capability *realized for that stage*.
+6. **Partial rebuild is valid.** Stage N can retire Bubble as *productive* home while Bubble remains *reference-only* for later capabilities.
+
+## Status labels
+
+### Capability priority (cut / roadmap)

+- Capabilities: `cap.<kebab>` — noun phrase of utility  
+  e.g. `cap.space-content`
+- Features: `feat.<kebab>` — verb/noun of implementation  
+  e.g. `feat.space-md-render`
+- Prefer stable ids; titles may change.

+# Decision: Stage-1 feature cut (productive transfer)
+
+| Field | Value |
+|-------|--------|
+| Id | CSOC-DEC-2026-001 |
+| Date | 2026-08-12 |
+| Status | **accepted** (founder direction; refine fields as product details firm up) |
+| Owner | bernd |
+| Workplan | CSOC-WP-0001-T03 |
+| Model | `docs/capability/model-v0.yaml` |
+| Narrative | `docs/capability/stage-1-cutover.md` |
+
+## Context
+
+coulomb.social rebuild runs on `app.coulomb.social` in parallel with Bubble on
+apex. Full Bubble parity is not required before transfer. We need an explicit
+**must** set so implementation and migration do not stall on marketplace-class
+scope, and so reductions are intentional.
+
+Discussion baseline: capability = utility, feature = implementation; practice
+capability model on coulomb first; HelixForge extraction later.
+
+## Decision
+
+1. **Partial rebuild is the strategy for stage 1.** Transfer users and retire
+   Bubble as the **productive** system when stage-1 capabilities work. Bubble
+   may remain as **implementation reference only** (not productive use).
+
+2. **Stage-1 must capabilities:**
+   - **User onboarding** (`cap.member-onboarding`)
+   - **Spaces with markdown content and CRUD**, including **Visual, Title,
+     Abstract** on space/page as product fields (`cap.space-content`)
+   - **Transfer of pages to other spaces** (`cap.page-transfer`)
+   - **Generate copy of page** (`cap.page-copy`)
+
+3. **Later use cases** (social, marketplace, monetization, full chrome parity,
+   etc.) extend the rebuild **after** stage 1; they do not block productive
+   transfer.
+
+4. **Capability/feature vocabulary and map** live in `docs/capability/` and
+   guide backlog and toggles. Feature toggles attach to features, not to
+   capability ids.
+
+## Consequences
+
+- Implementation backlog prioritizes space/page CRUD metadata + copy/move over
+  marketplace and social graph.
+- CSOC-WP-0001 migration/export targets stage-1 content and members first.
+- Public registration may complete via NetKingdom residual; transfer cohort may
+  use provisioned accounts if registration is late (open question in stage-1 doc).
+- ADR-0002 remains: page **bodies** markdown in Forgejo; Title/Abstract/Visual
+  may live in app DB and/or frontmatter — detail in implementation WPs.
+
+## Non-goals (stage 1)
+
+- Rebuild-as-is of all Bubble workflows  
+- Pixel-perfect Research UI  
+- In-app real-time collab editor (unless later promoted)  
+- HelixForge capability-management platform (extract later)
+
+## Open questions
+
+See `docs/capability/stage-1-cutover.md` § Open product questions (Visual
+storage, Abstract field naming, body editor UX, delete vs archive, transfer
+cohort auth).

+# CSOC-WP-0006 — Stage-1 space and page capabilities
+
+Implement product features required by the **stage-1 productive transfer** cut
+(`docs/capability/stage-1-cutover.md`, `docs/capability/model-v0.yaml`).
+
+**Out of scope here:** marketplace, social graph, monetization; Bubble export
+(CSOC-WP-0001-T02); public registration platform path (CSOC-IN-0001 / NK).
+
+## T01 — Space member CRUD + Title / Abstract
+
+```task
+id: CSOC-WP-0006-T01
+status: todo
+priority: high
+state_hub_task_id: "337baa68-0459-4985-9981-30a6d37f5bf5"
+```
+
+Member-facing create / update / archive (or delete) for `Space`. Expose
+**Title** and **Abstract** (current `description` field or rename). List and
+detail stay tenant-scoped. Tests for authz and isolation.
+
+## T02 — Space and page Visual
+
+```task
+id: CSOC-WP-0006-T02
+status: todo
+priority: high
+state_hub_task_id: "1ee74b60-a87d-4aff-91f1-3f97026774a5"
+```
+
+Add **Visual** (cover/image) for space and page. Decide storage (Forgejo
+`assets/` vs app media) in implementation notes; no secrets in git. Show
+visual on list/detail.
+
+## T03 — Page metadata + product CRUD path
+
+```task
+id: CSOC-WP-0006-T03
+status: todo
+priority: high
+state_hub_task_id: "fe95438c-2ed1-4efd-b6ea-84966636dbc3"
+```
+
+Structured **Title**, **Abstract**, **Visual** for pages; create/update/delete
+product path (app UI and/or API) while keeping markdown body SoR per ADR-0002
+(Forgejo commit or equivalent). Page list in space.
+
+## T04 — Generate copy of page
+
+```task
+id: CSOC-WP-0006-T04
+status: todo
+priority: high
+state_hub_task_id: "98d7428c-1b2f-45f1-b080-a833a4790b69"
+```
+
+`feat.page-duplicate`: independent copy with new slug/title; optional target
+space; asset handling per stage-1 acceptance.
+
+## T05 — Transfer page to another space
+
+```task
+id: CSOC-WP-0006-T05
+status: todo
+priority: high
+state_hub_task_id: "5ec81ff4-1d6f-4c86-8c93-b68b1570cc32"
+```
+
+`feat.page-move`: move page (+ agreed assets) with source and destination
+authz; no Bubble dependency.
+
+## T06 — Stage-1 smoke and capability model update
+
+```task
+id: CSOC-WP-0006-T06
+status: todo
+priority: medium
+state_hub_task_id: "752f52a8-8c18-402c-8f00-bce6c76a1db7"
+```
+
+Update `docs/capability/model-v0.yaml` feature statuses as work lands; extend
+`docs/identity/smoke.md` / deploy runbook with space CRUD, copy, transfer
+checks on app.coulomb.social.
+
+## Acceptance
+
+- [ ] Members can CRUD spaces with Title, Abstract, Visual without Django admin
+- [ ] Members can CRUD pages with Title, Abstract, Visual + markdown body path
+- [ ] Page copy and page transfer work with membership checks
+- [ ] Capability model statuses match reality
+- [ ] Stage-1 cut doc open questions resolved or explicitly deferred with owner
