🍪 biscuit: 🚧 not ready — auto-review, non-blocking
Review: Route HTTP hosts to named app services
The feature design is solid — the backward-compatibility strategy (empty service field defaults to web everywhere) is thought through, HTTPService validation at the CLI layer is correct, the lease-cache key is properly namespaced per service, and the unit tests for routeService, leaseCacheKey, and HTTPService cover the important cases. One concrete bug needs to be fixed before this ships.
Bug: plain-text route list table is misaligned
cli/commands/route_list.go adds "SERVICE" to the header slice (line 86), making it 9 columns, but the ui.Row built for each route in the plain-text path still only pushes 8 values — it inserts host, appDisplay, defaultDisplay, wafDisplay, timeoutDisplay, servingDisplay, createdAt, updatedAt and skips the service value entirely (lines 119–128). The JSON path is fine. The table render will either produce visually wrong output (column data shifted left under the wrong headers) or panic depending on what ui.AutoSizeColumns / ui.NewTable does with mismatched lengths. The blackbox test only checks JSON output (--format json), so this would slip past CI.
The fix is to insert routeService(route) into the ui.Row after appDisplay, matching the position of the "SERVICE" header.
Smaller concerns (not blocking individually, worth noting)
--service default stores "web" literally. The CLI defines default:"web" on the flag, so a plain route set example.com myapp now writes Service: "web" to the entity store, whereas older routes stored Service: "". Both display as web, routing is identical, but any tool that reads the raw entity will now see a non-empty field where it used to be absent. This is a deliberate trade-off (the comment acknowledges it), but worth being conscious of — if SetRoute ever needs to distinguish "explicitly set to web" from "legacy empty", that information is gone.
HTTPService with len(svc.Ports) == 0 && svc.Port == 0. When a service has neither Port nor Ports, the condition len(svc.Ports) == 0 && svc.Port > 0 is false, and the loop falls through to the else branch which iterates zero ports and never returns nil. The function then returns "has no HTTP port". That seems intentional — a service with no port config at all isn't HTTP-capable — but a future reader might be surprised that a zero-port service hits the "no HTTP port" path rather than a more descriptive error. Not a bug, just a subtle edge.

cli/commands/route_list.go:122
The SERVICE column was added to the headers (line 86) making it 9 columns, but this ui.Row only appends 8 values — the service value is absent. The table will render with misaligned columns. Insert routeService(route) between appDisplay and defaultDisplay to match the header order.

In cli/commands/route_list.go, the plain-text
route list table has a SERVICE column added to the
headers slice at line 86 (9 headers total), but
the ui.Row built for each route in the loop
starting around line 119 only has 8 values — it is
missing the service value. Add
`routeService(route)` to the ui.Row between
`appDisplay` and `defaultDisplay` so the row
matches the header order HOST, APP, SERVICE,
DEFAULT, WAF, TIMEOUT, SERVING, CREATED, UPDATED.

🍪 biscuit: ✅ ready to merge — auto-review, non-blocking
The blocking bug I flagged in my last review — the missing SERVICE value in the plain-text route list rows — has been fixed in commit e4e74f0. I can see it directly in the annotated diff: routeService(route) is now inserted at line 124 of cli/commands/route_list.go, between appDisplay and defaultDisplay, exactly matching the position of "SERVICE" in the 9-element header slice. The column count is now consistent.
The author also extended the blackbox test (blackbox/route_service_test.go) to check text output, checking for both the "SERVICE" header and the service value "echo" in the rendered table. That's a meaningful addition — the JSON path was already covered; the text path was the gap.
The docs update is solid too: the --service flag is now documented in route-set.md with a proper Docusaurus :::info admonition for the service constraint, matching the project's conventions.
My earlier secondary observations (the "web" literal default vs. empty-string legacy distinction, and the zero-port HTTPService path) remain accurate but neither is a bug — they're deliberate trade-offs the code comments acknowledge, and I'm not raising them as blocking concerns now.
This is ready to merge.

🤖 This check is stricter than the code that actually starts the service. A port with no type is valid and defaults to HTTP, but we reject it here. web also still gets its usual HTTP port 3000 when its configured ports are all TCP or UDP, and we reject that too. That means a plain route set can fail for configurations that already work. Could we reuse the launcher’s rules here, or cover the same cases and add tests?

🤖 Fixed in e341d3d: validation now follows appspec.Build, so an omitted port type defaults to HTTP and web remains HTTP-capable through its implicit port 3000 even when configured ports are non-HTTP.

🤖 Could this active-version lookup and service validation move behind the ingress client, perhaps as a service-aware SetRoute method? RouteSet now knows how app versions are stored, decodes core entities, and resolves runtime config only to enforce an ingress invariant. Keeping that orchestration at the write boundary would leave the command responsible for CLI input/output and make the same validation available to non-CLI route writers.

🤖 Fixed in e341d3d: active-version lookup, runtime-config resolution, and HTTP-service validation now live in ingress.Client.SetRoute, keeping the CLI focused on input and output while making the invariant available to any route writer.

Why this change
HTTP host routes currently always reach an app’s
webprocess. That prevents an app with a separately named HTTP API or dashboard process from exposing it through a hostname, even when that process is already part of the app’s active configuration. This change lets one hostname select one named HTTP-capable app service.Approach and choices
A route now stores an optional service name. An absent value still means
web, which keeps existing stored routes and existingmiren route set <host> <app>behavior compatible. The new--serviceflag defaults toweb; route creation validates the selection against the active configuration, including both currentports[]declarations and legacy scalar ports.The scope stays intentionally narrow. This does not add path-based routing, arbitrary port selection, automatic service selection, TCP/UDP hostname routing, or multi-service policies. Public ingress, internal requests, and tunnels use the selected service. Their lease-cache keys also include it, since reusing a lease across two services could proxy a request to the wrong process.
