+# Ship TODO
+
+## Open
+
+### ~~Support custom Caddyfile~~ ✅ FIXED
+**Fixed in:** commit b976b14
+
+- Caddyfile is only generated on first deploy
+- Redeploys preserve existing Caddyfile (manual edits survive)
+- SSH in and customize as needed, future deploys won't overwrite
+
+---
+
+### ~~ship list should show custom domains~~ ✅ FIXED
+**Fixed in:** commit c1b0bb8
+
+- Reads actual domain from Caddyfile instead of assuming subdomain
+- Works for both apps and static sites
+
+---
+
+## Fixed
+
+### ~~Port allocation collision bug~~ ✅ FIXED
+**Fixed in:** commit d97bb6f
+
+- Port allocation now uses atomic flock on `/etc/ship/next_port`
+- Prevents race conditions when multiple deploys run concurrently
+- Each app still gets its port stored in `/etc/ship/ports/<name>`
+
+### ~~Docker container port assumption~~ ✅ FIXED
+**Fixed in:** commit d97bb6f
+
+- Added `--container-port` flag (default 80)
+- Template now uses `{{.ContainerPort}}` instead of hardcoded 80
+- Supports containers that listen on 8080, 3000, etc.
+
+### ~~ship host init doesn't create local state.json~~ ✅ FIXED
+**Fixed in:** commit 6b2c047
+
+- Removed all v1 code (-2837 lines)
+- Simplified `internal/state/state.go` to just `default_host` + `base_domain`
+- `host init` now creates minimal state.json
+- Ports/deploys tracked on server at `/etc/ship/ports/`
