workstation: stop the Claude Code onboarding wizard reappearing for terminal users

emo reported being "logged out" on terminal.viktorbarzin.me: every new shell
dropped him at the first-run "Choose the text style" wizard, even though he'd
used many sessions and is in fact fully authenticated. Root cause is NOT a
logout — ~/.claude.json is a single file that all of a user's concurrent claude
processes (the ttyd terminal + their t3-serve instance + agent sessions)
read-modify-write, and a stale writer periodically drops top-level keys,
including hasCompletedOnboarding. That bounces the next interactive session back
to onboarding; credentials are safe in the separate ~/.claude/.credentials.json
(which is why T3 kept working). wizard's own ~/.claude.json showed the same key
loss, so this hits any heavy multi-session user.

Fix:
- skel/start-claude.sh: ensure_onboarding() idempotently re-asserts
  hasCompletedOnboarding (+ lastOnboardingVersion) in ~/.claude.json right before
  launching claude. Merge-only (never clobbers other keys), runs as the user, and
  no-ops if jq is missing or the file is empty/corrupt. So even if the race drops
  the flag, the next launch restores it before claude reads it.
- t3-provision-users.sh: deploy_user_launcher() re-copies skel/start-claude.sh
  into every non-admin home (copy-if-changed) on the hourly reconcile. /etc/skel
  only seeds the launcher at account creation, so without this the fix (and any
  future launcher edit) would never reach existing users. .tmux.conf is
  deliberately not re-copied — terminal-lobby appends a managed section to it.

 **Config inheritance (live):** wizard authors the base (his chezmoi-versioned `~/.claude`). Two native layers carry it to every user — the enforced org `claudeMd` in `/etc/claude-code/managed-settings.json` (top precedence, all sessions) and per-user `~/.claude/{skills,rules,…}` **symlinks** to the base (seeded via `/etc/skel`; edits propagate live). Secrets stay per-user at mode 600, never symlinked. **The managed config self-deploys from the repo** (2026-06-10): the hourly reconcile's `sync_managed_config` installs `scripts/workstation/managed-settings.json` to `/etc/claude-code/` whenever the repo copy changes — so editing the claudeMd = edit + commit, no manual install — and `refresh_codex_mirror` regenerates each user's `~/.codex/AGENTS.md` (a static mirror of the claudeMd; only files carrying the mirror header are touched, user-customized ones are left alone). Repo-level guidance (`.claude/CLAUDE.md`, `AGENTS.md`, `CONTEXT.md` in the infra repo) reaches non-admins through their auto-freshened clones — commit + push and every user has it within the hour.
 
+**Onboarding state self-heals (2026-06-15):** `~/.claude.json` is a single file that ALL of a user's concurrent `claude` processes (the ttyd terminal + their `t3-serve` instance + agent/SDK sessions) read-modify-write, so a stale writer periodically drops top-level keys — including `hasCompletedOnboarding` — which bounces the next *interactive* session back to the first-run "Choose the text style" wizard even though the user is fully logged in (credentials live in the SEPARATE `~/.claude/.credentials.json`, untouched by the race; first observed for emo 2026-06-15). The launcher (`skel/start-claude.sh`) now idempotently re-asserts `hasCompletedOnboarding` (+ `lastOnboardingVersion`) in `~/.claude.json` right before it runs `claude` — merge-only, never clobbers other keys, no-op if jq is missing or the file is empty/corrupt. And since the launcher is a per-user copy that `/etc/skel` only seeds at account creation, the reconcile's new `deploy_user_launcher` step re-copies `skel/start-claude.sh` into every non-admin home (copy-if-changed) so launcher edits now reach EXISTING users within the hour — `.tmux.conf` is deliberately NOT re-copied (terminal-lobby appends its own managed section to it).

 **Infra access:** non-admins get their own **writable, git-crypt-LOCKED** clone of the (public) infra repo — code/docs plaintext, secret files (`*.tfvars`, `secrets/**`) stay ciphertext. Its location depends on the per-user `code_layout` in `roster.yaml`: `single` (default) puts the clone AT `~/code`; `workspace` makes `~/code` a plain directory of per-project clones — the infra clone at `~/code/infra` plus each roster `repos` entry cloned from Forgejo `viktor/<name>` **as the user** (their PAT authenticates, so private repos work; clone failures WARN and retry next hour). Flipping a user to `workspace` auto-migrates their existing `~/code` clone to `~/code/infra` (local branches/dirty state survive; running processes follow the moved inode). ancamilea = workspace + `tripit` since 2026-06-10. The provisioner clones infra anonymously from the public GitHub mirror; **contribute access is wired per-user on top** (see below). The apply boundary still holds (`scripts/tg apply` needs an admin Vault token + cluster RBAC), but **pushing `master` is NOT inert** — the Forgejo→Woodpecker webhook fires `.woodpecker/default.yml` (`event: push, branch: master`, `require_approval: forks` only), which terragrunt-applies changed stacks. `master` is **branch-protected on Forgejo** (force-push disabled for everyone — history is append-only; push + merge whitelists = `viktor` + explicitly granted users, deploy keys allowed). **Allow-then-audit (Viktor, 2026-06-10):** `ebarzin` (emo) is on the whitelist and pushes straight to `master` — no PR gate. The tracking burden moves to: (a) **commit messages that record what + why** (the agent instructions in AGENTS.md and the managed claudeMd require the body to paraphrase the user's request), (b) the **`notify-nonadmin-push` Slack audit step** in `.woodpecker/default.yml` — every master push by a non-admin author is posted to Slack (admin pushes are not), and (c) non-admins **never use `[ci skip]`** so every change fires the pipeline (and thus the audit feed). Users NOT on the whitelist fall back to `<user>/<topic>` branches + PRs. **Clones stay fresh automatically** (2026-06-10): the hourly `t3-provision-users` reconcile runs `refresh_user_clone` over every managed clone — the infra clone and any workspace repos (fetch all remotes + fast-forward `master`, ONLY when on master with a clean tree and an upstream — dirty trees and local commits are left alone with a WARN) — and also `wire_forgejo_remote`, which idempotently adds the documented `forgejo` remote + `forgejo/master` upstream to infra clones that predate that contract. `start-claude.sh` does the same freshen at session launch (10s fetch cap per repo so an offline remote never stalls the session; workspace layouts freshen each repo under `~/code`).
