From 9b4ad55cd8cf669b6f2816d09dad76af889c3bd7 Mon Sep 17 00:00:00 2001 From: Quinn Ftw Date: Sun, 28 Dec 2025 02:18:21 -0800 Subject: [PATCH] feat(infra): add verification and rollback to Bash reconciliation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement "first step = last step" verification pattern for infrastructure reconciliation. After applying changes, the system re-probes to verify state matches expectations, with rollback capability on failure. New components: - lib/verify.sh: Core verification library with snapshot/verify/rollback - state-snapshots/: Pre-reconciliation state storage (gitignored) - Service handlers: Added _state_hash() to all 8 services New CLI flags: - --auto-rollback: Automatic rollback on verification failure - --no-rollback: Log failures without rollback - --verify-only: Re-verify without applying changes - --list-snapshots: List available snapshots - --show-snapshot: Display snapshot details Rollback capability matrix: - reversible: hostname, services, agent, cron, files - partial: packages, dns, users (may have side effects) - irreversible: firewall, vpn, certs (manual intervention) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- infrastructure/reconciliation/.gitignore | 2 + .../inventory/hosts/apricot.conf | 2 +- .../reconciliation/inventory/hosts/black.conf | 2 +- .../inventory/hosts/macbook.conf | 2 +- .../reconciliation/inventory/hosts/ns2.conf | 2 +- .../inventory/hosts/vpn-gateway.conf | 2 +- .../reconciliation/inventory/hosts/vps.conf | 3 +- infrastructure/reconciliation/lib/service.sh | 114 +++++ infrastructure/reconciliation/lib/verify.sh | 426 ++++++++++++++++++ infrastructure/reconciliation/reconcile | 240 +++++++++- .../reconciliation/services/health-monitor.sh | 39 ++ .../services/host-status-monitor.sh | 179 +++++++- .../services/nginx-config-sync.sh | 62 +++ .../services/nginx-whitelist.sh | 18 + .../reconciliation/services/socks5-tunnel.sh | 45 ++ .../services/ssl-certificate.sh | 20 + .../services/status-dashboard.sh | 18 + .../services/wireguard-client.sh | 39 ++ .../reconciliation/state-snapshots/README.md | 16 + 19 files changed, 1201 insertions(+), 30 deletions(-) create mode 100644 infrastructure/reconciliation/.gitignore create mode 100644 infrastructure/reconciliation/lib/verify.sh create mode 100644 infrastructure/reconciliation/state-snapshots/README.md diff --git a/infrastructure/reconciliation/.gitignore b/infrastructure/reconciliation/.gitignore new file mode 100644 index 000000000..a454f82a4 --- /dev/null +++ b/infrastructure/reconciliation/.gitignore @@ -0,0 +1,2 @@ +state-snapshots/* +!state-snapshots/README.md diff --git a/infrastructure/reconciliation/inventory/hosts/apricot.conf b/infrastructure/reconciliation/inventory/hosts/apricot.conf index 6a0a9cb68..aa648a125 100644 --- a/infrastructure/reconciliation/inventory/hosts/apricot.conf +++ b/infrastructure/reconciliation/inventory/hosts/apricot.conf @@ -9,7 +9,7 @@ ROLE="workstation" #
