workstation: docs — multi-tenancy Workstation section + offboard runbook + service-catalog fix [ci skip]

Browse source 
multi-tenancy.md: new DevVM Workstation section (roster SSoT, tiers, config inheritance, locked clone, built-vs-gated status). service-catalog.md t3code row: corrected the stale 'source of truth = /etc/ttyd-user-map' (now roster.yaml; the map/dispatch are GENERATED). offboard-user.md: written (was a referenced-but-missing dead link) — staged reversible-cut-then-gated-destructive for both cluster + workstation surfaces.

| k8s-dashboard | Kubernetes dashboard at `k8s.viktorbarzin.me`. **Forward-auth + auto-injected SA token** (apiserver OIDC blocked, see design §12). nginx token-injector (`dashboard_injector.tf`) maps `X-authentik-username` → the user's `dashboard-<user>` SA token (ns admin + read-only on namespace-list/nodes only via `dashboard-nav-readonly` — no cross-tenant reads, `rbac/.../dashboard-sa.tf`; admins → cluster-admin SA) and sets `Authorization: Bearer` → no token-paste, dashboard auto-authenticates per user. Forward-auth admits `kubernetes-*` groups for this host (`stacks/authentik/admin-services-restriction.tf`). oauth2-proxy + `k8s-dashboard` OIDC app built but idle. | k8s-dashboard |

| t3code | Multi-user coding-agent GUI at t3.viktorbarzin.me. `auth=required` (Authentik) → DevVM `t3-dispatch` service (`10.0.10.10:3780`, unprivileged user) maps `X-authentik-username` → that user's own `t3-serve@<u>` instance (file perms enforced by uid; wizard→:3773, emo→:3774; unmapped→403) and **auto-injects the t3 session on first visit** (mints via the root `t3-mint` wrapper, scoped sudoers → `/api/auth/bootstrap` `t3_session` cookie). Source of truth `/etc/ttyd-user-map`; `t3-provision-users` reconcile (systemd timer) turns map entries into `t3-serve@<u>` instances + `dispatch.json`. **Add a user:** one line in `/etc/ttyd-user-map` (must already be an OS account + Authentik identity) → reconcile. DevVM artifacts versioned in `infra/scripts/` (`t3-serve@.service`, `t3-provision-users`, `t3-dispatch/`, `t3-mint`, `sudoers-t3-autopair`, `t3-autoupdate.*`); TF (`stacks/t3code`) owns only the ingress + Endpoints→:3780. **t3 binary tracks `nightly`** via `t3-autoupdate` (daily systemd timer; health-check + auto-rollback on a bad build; restarts only idle instances) — so new models (e.g. Opus 4.8) land as t3 ships them. Native app/app.t3.codes unsupported (cross-origin) — deferred until published. Design: `docs/plans/2026-06-01-t3-auto-provision-*`. | t3code |

New non-admins inherit wizard's Claude config (machine-wide managed `claudeMd` in `/etc/claude-code/managed-settings.json` + per-user `~/.claude/{skills,rules}` symlinks seeded by `/etc/skel`) and get a **writable git-crypt-LOCKED** infra clone at `~/code` (code plaintext, secret files ciphertext). Tiers: admin / power-user (cluster-wide read-only) / namespace-owner. **Add a user:** one entry in `roster.yaml` → reconcile (the per-user OIDC kubeconfig + Authentik `T3 Users` gate are separate gated cluster/auth applies).
