Problem

On every boot registration the relay's reconcileOrigin returned ready as soon as the allocation's recorded origin matched the host's, without reading the tunnel's live Cloudflare ingress. If the ingress had drifted to another port (in the report: ingress http://127.0.0.1:4711, allocation and server 127.0.0.1:3773), the tunnel stayed healthy but proxied to a dead port, clients saw 502 / origin_unreachable, and restarting T3 Code changed nothing because the restart takes the same matching-origin path. Reproduced on main as a provider test: provision at 3773, move the tunnel's ingress to 4711 behind the relay's back, call reconcileOrigin with 3773, and it returns ready with the ingress still on 4711.

Change

• reconcileOrigin now reads the tunnel's configuration when the recorded origin matches. If the hostname's ingress rule already serves the origin, it returns ready with no write. Otherwise it falls through to the existing claimed putConfiguration + markReady path that already repairs a changed origin, so every boot registration converges the ingress.
• The tunnel client gains a getConfiguration operation wired to the Cloudflare binding. Cloudflare reports a tunnel with no remote configuration as TunnelConfigurationNotFound (code 1055, not a 404), so the binding reads that as empty ingress and the rewrite runs. A missing tunnel still returns recovery_required.
• The cost is one gated Cloudflare read per registration whose origin matches. The recovery path (reuseReadyTunnel) is unchanged.

Scope and approval

Fixes #27952

Triaged via the automated issue flow.

Verification

Focused tests in infra/relay/src/environments/ManagedEndpointProvider.test.ts:

• restores Cloudflare ingress that drifted from the recorded origin: a registration whose ingress already serves the origin only reads (get, getConfiguration), then the ingress drifts to 4711 and the next registration rewrites it to 3773.
• reads a tunnel without remote configuration as having no ingress: Cloudflare's code-1055 response through the real binding.

Server-only (relay) change with no rendered surface, so there are no captures. Not checked: a run against the live Cloudflare API. Whether Cloudflare echoes the service string back exactly as the relay writes it is assumed, not observed; if it normalised it, a matching registration would rewrite on each boot rather than fail.

Approvability

Verdict: Approved at 9920d41

Macroscope's review found this PR approvable — Tunnel reconciliation now checks live ingress and repairs drift even when the recorded origin already matches. Repairs remain scoped to the validated managed allocation and use the existing guarded configuration-update path.

Walkthrough

The tunnel client now reads Cloudflare ingress configuration. When the recorded origin matches, reconciliation checks live ingress and proceeds to repair if the matching rule does not serve the requested origin or has a path restriction.

Changes: Managed tunnel ingress reconciliation

Layer / File(s)	Summary
Tunnel configuration reads infra/relay/src/environments/ManagedEndpointProvider.ts, infra/relay/src/environments/ManagedEndpointProvider.test.ts	The tunnel client adds a configuration-read operation. The Cloudflare binding returns ingress rules, treats missing configuration as empty ingress, and maps other failures to client errors. Tests add configuration-aware mocks and cover the missing-configuration response.
Ingress verification and repair infra/relay/src/environments/ManagedEndpointProvider.ts, infra/relay/src/environments/ManagedEndpointProvider.test.ts, infra/relay/src/environments/ManagedEndpointReaper.test.ts	When the recorded origin matches, reconciliation checks the first matching exact-host, wildcard, or catch-all rule. It returns ready only if the service matches and the rule has no path; otherwise, it continues to configuration repair. Tests cover service drift, wildcard ordering, and path removal. The reaper test client adds a getConfiguration stub.

Full details: Title check

Explanation

The title names the main change: reconcileOrigin now repairs tunnel ingress that drifted from a matching origin. It also names the relay scope. It follows the conventional commit form used in the repository template, and the title is 81 characters long, which is longer than ideal but still readable.

Full details: Description check

Explanation

The description covers the required template sections. Problem explains the drift bug, the failing behavior, and a reproduction. Change explains the fix, the new getConfiguration operation, and the code-1055 handling. Scope and approval links issue #27952 and states the triage path. Verification lists the focused tests, a red/green transcript, the check command results, and what was not checked, including the live Cloudflare API run. The description does not show an explicit maintainer approval comment, so the Scope and approval section relies on a triaged issue reference. That is a gap the reviewer should confirm, but the section is otherwise complete.

Full details: Linked Issues check

Explanation

Issue #27952 requires live ingress verification when recorded and host-reported origins match, plus repair when ingress differs. reconcileOrigin now calls getConfiguration, selects the managed hostname, wildcard, or catch-all rule, and returns ready only when the service matches and the rule has no path restriction. Otherwise it uses the existing guarded configuration update and markReady path. The Cloudflare binding treats code 1055 as empty ingress, so reconciliation repairs the configuration; missing tunnels retain recovery_required. Focused tests cover matching reads, drift repair, path-restricted rules, and code-1055 handling.

Full details: Out of Scope Changes check

Explanation

The changes remain within issue #27952. The getConfiguration client operation and code-1055 mapping support live ingress verification. The path field and path-restricted-rule test prevent a false ready result. Test-fixture updates support the new client method and behavior. No unrelated product surface or administrative changes are present.

Follow-up Comments

Check the effective ingress rule before returning ready.

803-804: Major · Stability & Availability · Quick win

Check the effective ingress rule before returning ready.

The managed hostname is a subdomain of t3code.test, so an earlier *.t3code.test rule can match it. reconcileOrigin currently selects a later exact-hostname rule and can report ready even when Cloudflare routes the request through the earlier wildcard rule.

Select the first matching rule, including wildcard hostnames, before skipping repair.

Suggested fix

         const hostname = normalizeHostname(allocation.hostname);
         const rule = configuration.value.ingress.find(
-          (entry) => entry.hostname != null && normalizeHostname(entry.hostname) === hostname,
+          (entry) => {
+            if (entry.hostname == null) return true;
+            const ruleHostname = normalizeHostname(entry.hostname);
+            return (
+              ruleHostname === "*" ||
+              ruleHostname === hostname ||
+              (ruleHostname.startsWith("*.") && hostname.endsWith(ruleHostname.slice(1)))
+            );
+          },
         );

Add a regression test with *.t3code.test before the exact-hostname rule. The affected tunnel can otherwise report ready while requests return 404.
