Seed the org refactor: goal, scope, blast radius, entry gate

Establishes the prj- flavor baseline (GOAL.md, SCOPE.md, AGENTS.md,
.repo-classification.yaml, genesis, foundation workplan) for splitting the
single coulomb/ Forgejo org into stewardship orgs.

Records the blast radius verified 2026-08-11: 112 repos with a coulomb/ origin,
ArgoCD repoURL sources, Chart.yaml metadata, and - the finding that made this
project-sized rather than workplan-sized - container image paths, since
Forgejo's package registry is org-scoped. That failure is deferred: it does not
appear at rename time but at the next pod reschedule.

Seeded deliberately deferred per operator decision. ORGREF-WP-0001 is backlog
and carries a four-part entry gate (validator live, deployable coverage known,
stable re-runnable inventory, demonstrated rollback) so the decision to start
is made against evidence rather than memory. T01 and T02 are read-only and safe
to advance at any time.

+# SCOPE
+
+> Lightweight orientation: what this project repo is for, and when it is not
+> the right place to work.
+
+---
+
+## One-liner
+
+Temporary coordination repo for splitting the single `coulomb/` Forgejo
+organization into stewardship organizations without breaking GitOps, image
+pulls, or clones.
+
+---
+
+## Project authority
+
+This repo **coordinates**. It owns the inventory, the org taxonomy, the
+sequencing, the rollback plan, and the evidence. It does **not** own the repos
+being moved, and it hosts no production implementation.
+
+Changes land in the repos that own them. This project links their work records
+by ID; it does not duplicate their tasks.
+
+---
+
+## In Scope
+
+- Inventory of every `coulomb/` reference across the fleet
+- Target org taxonomy and the assignment criteria behind it
+- Verification of Forgejo rename / transfer / redirect behavior, including the
+  package registry
+- Migration sequencing, rollback plan, and cutover evidence
+- Promotion of the durable org-assignment convention to a permanent home
+
+---
+
+## Out of Scope
+
+- Rapp context grouping — a separate dimension by ratified decision
+  (`d07ee5f9`); see `railiance-platform/docs/rapp-platform-service-pattern.md`
+- State Hub domain taxonomy — a separate dimension, owned by the-custodian
+- Legal-entity structure and IP attribution — handled by `LICENSE`, copyright
+  headers, and `contribution-convention_v0.1`
+- Renaming the `forgejo.coulomb.social` host (open question, may become scope
+  only if the org split forces it)
+- Any repo's internal structure or content
+
+---
+
+## Participating repos
+
+| Repo | Role |
+| --- | --- |
+| `railiance-forge` | Forgejo runtime owner — executes org/transfer operations |
+| `railiance-platform` | ArgoCD Application sources, OpenBao lanes referencing repo URLs |
+| `railiance-apps` | Chart image `repository:` paths and chart metadata |
+| `railiance-master` | Durable home candidate for the org-assignment convention |
+| `the-custodian` | Canon home candidate; repo-classification alignment |
+| all 112 `coulomb/` repos | Subjects of the migration |
+
+---
+
+## Relevant When
+
+- Planning or executing the Forgejo org split
+- Deciding which org a **new** repo should be created in (until G7 promotes
+  that convention to a permanent home)
+
+## Not Relevant When
+
+- Deciding which rapp a workload belongs to (different dimension)
+- Deciding which State Hub domain work belongs to (different dimension)
+- The entry gate in `GOAL.md` is not yet met — the project is deliberately
+  parked until then
+
+---
+
+## Work-record rule
+
+Workplan files live in `workplans/` with prefix `ORGREF-WP-NNNN`. Child work in
+participating repos keeps its own prefix and is linked by stable ID from this
+project's workplans, never copied.
+
+---
+
+## Current State
+
+- Status: **draft, deliberately deferred**
+- Seeded 2026-08-11 with the finding, blast radius, and entry gate
+- Execution begins only when the `ORGREF-WP-0001` entry gate is met
