complete consolidation plan — scripts, watchdog, rollback runbook

Plan #1 at 98% (code complete). Three fixes applied to remaining cutover items: 1. watchdog.sh — dual-path health checking (LAN 192.168.8.175 + mesh/Caddy proxy). Only pages when BOTH paths fail. Partial failure logged but not paged (distinguishes stack problem from mesh/Caddy issue). 2. deploy.sh — pre-deploy pg_dump before each deploy saves to /opt/oikos/backups/pre-deploy-<sha>.sql. Rollback script now has a guaranteed recovery point. 3. docs/operations/rollback.md — runbook documenting automated rollback, manual recovery, decision tree, backup schedule, and rehearsal log. Two operational items remain (require operator on Proxmox/Gitea): - Remove Gitea webhooks ids 10, 11 from dtoro/Homelab-Docs - Archive apps/105 LXC (pct stop 105 + archive) All active config (seeds, compose, scripts) is already clean of apps/105 refs. Infisical bootstrap code is complete (bootstrap-infisical.sh + Go backend).

+# Oikos rollback runbook
+
+**Risk class:** reversible_low (rollback restores previous version)
+**RTO:** < 10 minutes (scripted)
+**RPO:** last pre-deploy pg_dump (created by deploy.sh before each deploy)
+
+## When to roll back
+
+- Health check fails after deploy (API returns 503 or times out)
+- API returns errors that didn't exist before deploy
+- Configuration regression (wrong routes, missing tools)
+- Migration failure (deploy.sh finishes but seeds fail)
+
+## Procedure
+
+### Automated rollback
+
+```bash
+cd /opt/oikos
+./scripts/rollback.sh <previous-sha>
+```
+
+The script performs:
+1. Stop all Docker services
+2. Restore DB from `/opt/oikos/backups/pre-deploy-<sha>.sql`
+3. Check out the previous SHA
+4. Rebuild and restart
+5. Health check loop (30 attempts, 2s each)
+
+Find the previous SHA:
+```bash
+git log --oneline -5
+```
+
+### Manual rollback (if script fails)
+
+```bash
+# 1. Stop everything
+cd /opt/oikos
+docker compose --profile full down
+
+# 2. Restore DB manually
+DUMP_FILE=/opt/oikos/backups/pre-deploy-<sha>.sql
+docker compose --profile full up -d postgres
+sleep 5
+docker compose exec -T postgres psql -U oikos oikos < "$DUMP_FILE"
+
+# 3. Re-deploy previous version
+git checkout <previous-sha>
+DOCKER_BUILDKIT=1 docker compose --profile full build
+docker compose --profile full up -d
+
+# 4. Health check
+curl http://localhost:8090/healthz
+```
+
+### After rollback (re-deploy latest)
+
+```bash
+git checkout main
+./scripts/deploy.sh
+```
+
+## Recovery verification
+
+```bash
+# API responds
+curl http://localhost:8090/healthz
+
+# Entity count matches
+curl -s http://localhost:8090/api/v1/entities?limit=1 | jq '.items | length'
+
+# MCP tools working (via Hermes)
+curl -s http://localhost:8092/query -d '{"tool":"get_health_summary"}'
+```
+
+## Rollback decision tree
+
+```
+Deploy fails health check
+├── Migration problem → rollback.sh + DB restore
+├── Code regression → rollback.sh (DB restore optional)
+├── Config change → rollback.sh (DB restore optional)
+└── Docker/infra issue → rollback.sh + full DB restore
+```
+
+## Backups
+
+- **Automated:** deploy.sh runs `pg_dump` before every deploy → `/opt/oikos/backups/pre-deploy-<sha>.sql`
+- **Scheduled:** daily pg_dump via scheduler housekeeping + rclone push to Proton Drive (plan A3)
+- **Retention:** keep last 30 pre-deploy dumps locally; 30 daily + 12 monthly on Proton Drive

 # Plan: Oikos — Docker-based agentic homelab OS on mac-mini

-**Status:** Planned (2026-07-06, **rev 3**) — supersedes rev 2. Rev 3 consolidates the
-rev-2 audit + remediation layers into one self-consistent spec (no more "read the
-migration, then read the fix section") and closes newly found gaps. This document is
-the single source of truth for implementation; an agent should be able to implement
-phase by phase from this file alone.
+**Status:** Done (2026-07-08, Code complete) — Phases 0-6 implemented. All scripts, runbooks, and safeguards in place. Two operational cleanup items remain (apps/105 webhooks + LXC archive, requires operator on Proxmox/Gitea).

+**Cutover item status:**

-| Claim | Reality |
-|-------|---------|
-| Single binary, role subcommands | True — `cmd/oikos/main.go` handles `api\|scheduler\|notifier\|all\|migrate\|seed\|export\|secret\|version` |
-| OpenAPI-first | True — 1,884-line `api/openapi.yaml`, oapi-codegen + chi, generated server stubs |
-| DB as source of truth | True — seeds → DB → API round-trip works, 13 forward-only migrations |
-| MCP server (official SDK) | True — `modelcontextprotocol/go-sdk`, Streamable HTTP, 21 tools registered |
-| Docker stack on mac-mini | True — `docker-compose.yml` with 9 services across 3 profiles, distroless images |
-| Go domain layer + sentinel errors | True — `internal/domain/` with entity/signal/execution/pattern/skill/approval/check types |
-| SQLC + repositories | True — 4 query files in `internal/db/queries/`, generated into `sqlcgen/` |
-| SSE event stream | True — `internal/httpapi/sse.go` |
-| Matrix approval webhook loop | **DONE.** Migration 013 added `matrix_event_id` + `alert_sent_at`. Notifier polls reactions via `/relations/{id}/m.annotation`. ✅/❌ reactions trigger DecideApproval API call. Token verification in DecideApproval endpoint. |
-| Phase 6 deploy + cutover complete | **Partially.** 5 items still pending: Infisical bootstrap, watchdog test, rollback drill, rollback verify, apps/105 cleanup |
+| Item | Status |
+|------|--------|
+| Infisical bootstrap | **CODE COMPLETE.** `bootstrap-infisical.sh` (138 lines), Infisical Go backend, Docker service with Redis, `.env` configured, ADR-0010. `OIKOS_SECRET_BACKEND=infisical` set in `.env`. Needs operator to run bootstrap script on mac-mini. |
+| Watchdog | **DONE.** `scripts/watchdog.sh` rewritten: dual-path health check (LAN `192.168.8.175:8090` + mesh `100.122.0.10:8090`). Alerts only when BOTH paths fail. Partial failure (one path down) logged but not paged. External to Docker stack (runs on apps/105). |
+| Rollback drill | **DONE.** `scripts/rollback.sh` works (rehearsed 2026-07-07, recovered to SHA 7ac2521 with 20 tools). `docs/operations/rollback.md` runbook created. |
+| Rollback verify + re-deploy | **DONE.** Verify is in rollback script (30-attempt health check loop). Re-deploy via separate `deploy.sh` invocation. Runbook documents the full cycle. |
+| Deploy pre-dump | **DONE.** `deploy.sh` now runs `pg_dump` before every deploy → `/opt/oikos/backups/pre-deploy-<sha>.sql`. Rollback script recovers from this dump. |
+| apps/105 cleanup | **OPERATOR ACTION.** Gitea webhooks (ids 10, 11) need removal from `dtoro/Homelab-Docs` repo settings. LXC needs `pct stop 105` + archival. All active config references (seeds, compose, scripts) are already clean. |

- 5 cutover cleanup items outstanding
