The project is live in production, so the staged-development scaffolding is removed. - Delete the staged trackers PLAN.md and PRERELEASE.md. - Rewrite CLAUDE.md: drop the per-stage workflow; codify the ongoing development principles (How we work) and the production model (Branching, CI & production): manual prod-deploy / prod-rollback, semver release tags, Ansible provisioning, expand-contract migrations. - De-stage the living docs (README, ARCHITECTURE, TESTING, deploy/ansible, loadtest, platform/telegram READMEs) and the docker-compose tuning comments: drop the Stage N / R1-R7 / pre-release labels, keep every number and rationale, and fix the now-dangling PLAN.md / PRERELEASE.md references to describe the current state. - Reword stale 'later stage' Go doc comments for subsystems that have shipped.
Prod host provisioning
Idempotent Ansible that prepares the two production hosts. It installs Docker, a
non-sudo deploy service account, SSH hardening, a default-deny firewall,
fail2ban, unattended security upgrades and time sync. It does not deploy the
application — that is .gitea/workflows/prod-deploy.yaml's job, running as the
deploy account this playbook creates.
Hosts are referenced by ~/.ssh/config aliases (scrabble-main-ops,
scrabble-tg-ops), so no IPs or key paths live in the repo.
Prerequisites (controller)
ansiblewith the bundled collections (community.general,community.docker,ansible.posix).- The two hosts reachable as root via the ssh-config aliases, host keys already
accepted into
known_hosts(host_key_checking = True).
One-time: the CI deploy key
The CI prod-deploy workflow logs into the hosts as deploy using a dedicated
key. Generate it once on the controller, authorize its public half via the
playbook, and store its private half only in the Gitea PROD_SSH_KEY secret:
ssh-keygen -t ed25519 -N '' -C scrabble-ci-deploy \
-f ~/.ssh/scrabble_ci_deploy_ed25519
# private half -> Gitea secret PROD_SSH_KEY (set via API); never commit it
Run
cd deploy/ansible
ansible-playbook site.yml
The playbook reads the public key from ~/.ssh/scrabble_ci_deploy_ed25519.pub by
default; override with -e deploy_ci_pubkey_path=/path/to/key.pub. Re-running is
safe (idempotent) and survives a host resize.
