Introduce tenant-scoped Space/SpaceMembership with list and detail views.
Document markdown-in-Forgejo as content SoR (ADR-0002). Run migrations on
container start so app.coulomb.social picks up the new tables.
Post-login lands on Spaces empty state instead of a principal dump.
Profile menu exposes Session details with identity, tenant, roles/groups,
and authz diagnostics for operator refinement (CSOC-WP-0004 T01/T07).
Local + HTTP POST /v1/check PEP with fail-closed transport errors;
shell:view enforced on /app/. Vocabulary docs for T07. Helm chart lives
in railiance-apps; Dockerfile already present for T08.
HttpUserEngineClient uses trusted-proxy claims against live user-engine.
Offline stub when URL/secret unset. Align default tenant with KeyCape
tenant:coulomb; map OIDC tenant/principal_type/groups into the envelope.
Django scaffold aligned with the business delivery lane: tenant-keyed
Member model without passwords, identity app as sole OIDC/session
boundary, dev-claims login, authenticated /app/ shell, ADR-0001, and
tests. T01/T02/T05/T06 done; OIDC registration, real user-engine HTTP,
flex-auth, and packaging remain open.
