Bootstrap coulomb-social: INTENT, SCOPE, TRSL, agent files, State Hub

Prepare the greenfield rebuild of coulomb.social (bubble.io exit) with
orientation docs, TRSL license, Claude/Codex agent integration, and repo
classification under domain communication / topic coulomb-social. Workplan
CSOC-WP-0001 (exit assessment) is already registered via fix-consistency.

+> when it is relevant, and when it is not.

+
+## One-liner
+
+Reimplementation of the coulomb.social co-creation platform as a standalone Railiance / NetKingdom / HelixForge application, exiting the stalled bubble.io stack.
+
+---
+
+## Core Idea
+
+coulomb.social connects people around shared projects and complementary capabilities. Development on bubble.io has stalled. This repo owns the full product rebuild — UI, content, data model, and migration — so the platform can evolve with the rest of the Coulomb agentic fleet under the business-app service contract.
+
+---
+
+## In Scope
+
+- Product intent, scope, workplans, and ADRs for the coulomb.social rebuild
+- Inventory of the existing bubble.io app (pages, workflows, data types, integrations, content)
+- Data export, relational schema mapping, and migration rehearsal
+- Feature-cut decisions (rebuild-as-is vs reduced v1) and acceptance criteria
+- Application implementation: UI parity, domain model, app-local accounts, APIs
+- Packaging for the business delivery lane (commit-SHA images, railiance-apps release values)
+- Tenant-keyed data model from the first migration; member account export/delete
+- Ops/runbook stubs required by the business-app service contract (§§3–6)
+- State Hub workplans, progress events, and classification for this repo
+
+---
+
+## Out of Scope
+
+- Remaining on bubble.io as the primary development platform
+- Owning Railiance cluster, platform, or app-chart infrastructure code (`railiance-*`)
+- Owning NetKingdom identity platform implementation (Keycloak/OpenBao) — only the app-local auth boundary and future OIDC switch point live here
+- Owning HelixForge standards or capability registry implementation
+- Core Hub embedding or treating coulomb.social as a hub extension
+- Fleet self-improvement loops (owner: `coulomb-loop`)
+- Serving paying external multi-tenant SaaS before the service-contract preconditions are met
+
+---
+
+## Relevant When
+
+- Planning or implementing the bubble.io exit and product rebuild
+- Mapping coulomb.social features, content, or data into code-owned artifacts
+- Packaging or deploying the coulomb.social app via the business delivery lane
+- Checking tenancy, identity, backup, or cost-attribution obligations for this app
+
+---
+
+## Not Relevant When
+
+- You need cluster or mesh infrastructure changes → use the relevant `railiance-*` repo
+- You need platform SSO/secret custody work → use `net-kingdom` / OpenBao workplans
+- You need fleet kaizen loop operation → use `coulomb-loop`
+- You need a reference business-app implementation pattern → start with `vergabe-teilnahme`
+- You only need the historical seed note → `the-custodian/docs/coulomb-social-rebuild-seed.md` (pointer; work originates here)
+
+---
+
+## Current State
+
+- Status: bootstrap / greenfield
+- Implementation: orientation docs only; no application code yet
+- Stability: evolving
+- Usage: internal — product rebuild not yet serving members from this stack
+- Prior art: rebuild seed from CUST-WP-0058-T08; topic `coulomb-social` already exists in State Hub under domain `communication`
+
+---
+
+## How It Fits
+
+- **Upstream decisions:** business-app service contract; DR-1 C / DR-2 B / DR-3 A
+- **Delivery lane:** `vergabe-teilnahme` (pattern) → this repo (product) → `railiance-apps` (release values) → railiance01
+- **Platform peers:** `railiance-*`, `net-kingdom`, `helix-forge`, `ops-hub`, `fin-hub`
+- **Coordination:** State Hub topic `coulomb-social` (domain `communication`); related engagement repo `coulomb-loop`
+
+---
+
+## Getting Oriented
+
+- Start with: `INTENT.md`, `GOAL.md`, `.custodian-brief.md`
+- Key paths: `workplans/`, `docs/` (as they appear), application source (once scaffolded)
+- First workplan: `workplans/CSOC-WP-0001-bubble-io-exit-assessment.md`
+- Contract: `the-custodian/canon/standards/business-app-service-contract_v0.1.md`
