-A simple self-hosted PaaS that auto-deploys Docker containers from Git repositories via Gitea webhooks.
+A simple self-hosted PaaS that auto-deploys Docker containers from Git repositories via webhooks from Gitea, GitHub, or GitLab.
 
 ## Features
 
 - Single admin user with argon2id password hashing
 - Per-app SSH keypairs for read-only deploy keys
-- Per-app UUID-based webhook URLs for Gitea integration
+- Per-app UUID-based webhook URLs with auto-detection of Gitea, GitHub, and GitLab
 - Branch filtering - only deploy on configured branch changes
 - Environment variables, labels, and volume mounts per app
+- CPU and memory resource limits per app
 - Docker builds via socket access
 - Notifications via ntfy and Slack-compatible webhooks
-- Backup/restore of app configurations (JSON export/import via UI and API)
 - Simple server-rendered UI with Tailwind CSS
 
 ## Non-Goals

+# Workflow
+
+* branch (from `main`)
+* do the work in Next Step
+* move Next Step to the top of Completed Steps
+* move the top item of Future Steps into Next Step
+* commit (`TODO.md` changes in the same commit as the work)
+* merge to `main` if the branch is not protected, otherwise open a PR
+* push
+
+# Status
+
+1.0+. Tagged 1.0.0 on 2026-02-26; 8 commits on main since. Policy
+violation: main currently fails make check (91 lint issues), so the tree
+is out of compliance until fixed.
+
+# Next Step
+
+Fix the 47 noctx lint findings (HTTP requests without context) in one
+commit and confirm the count drops under make check. This is the largest
+of the three lint classes blocking a green main.
+
+# Completed Steps
+
+- 2026-03-11: Monolithic env var editing with bulk save (#158).
+- 2026-03-10: Webhook event history UI page (#164); added missing
+  Makefile docker and hooks targets plus test timeout (#159);
+  notification settings passed from create form (#160).
+- 2026-03-03: REPO_POLICIES compliance file set added (#155).
+- 2026-03-01: Module path changed to sneak.berlin/go/upaas (#143);
+  Dockerfile split into lint and build stages with forced lint
+  execution (#152, #154).
+- 2026-02-26: 1.0.0 tagged; dashboard CSRFField crash fixed (#146).
+- 1.0 audit bug fixes (#120-#125): deferred rollback on commit error,
+  deployment log size cap, error path rendering, docker-compose bind
+  mount, domain type refactor.
+- CI simplified to docker build only (#130).
+- 2025-12-29 onward: core PaaS built out: deploys with real-time build
+  log streaming, container start/stop/restart and logs, TCP/UDP port
+  mapping, Alpine.js UI, Slack notifications, ULID app IDs, session
+  handling.
+
+# Future Steps
+
+- Get main green (compliance, ordered):
+    - Fix 47 noctx findings (Next Step).
+    - Fix 23 gosec findings.
+    - Fix 21 goconst findings.
+    - Run make check clean on main and keep it green; main must always
+      pass.
+- Confirm .gitea/workflows/check.yml gates merges on make check so main
+  cannot regress.
+- Resume feature work only after main is green.
