Ilker ManapandClaude Opus 5.5	abaf086fd5	A standby's portal is the leader's; the changelog as the release notes read it ... A proxy left pointing at a standby showed an empty cluster: the portal and the admin pages read the standby's own memory. A standby now passes its client port to the leader's, all but /health, /ready and /leader, which must describe the machine a load balancer is choosing; and its admin port passes the dashboard as well as the API. The leader trusts the control planes' X-Forwarded-For, so clients keep their own address. The changelog's candidate section is "Unreleased" again: release notes for an rc read that section, and v0.11.3-rc.1 got none. The e2e wait for two endpoints is 30s: under the race detector on a busy runner, 15s was missed once. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>	2026-10-05 06:34:57 +02:00
Ilker ManapandClaude Opus 5	1c57a4e378	Let the catalog change while the cluster is running ... Adding a model was an operator procedure with downtime: edit a file on the control plane, restart it, wait out the settling window, watch replicas churn while adoption catches up. I did that eight times in a day, and one of the restarts cost two minutes of outage while stalled replicas timed out. None of it was necessary. The reconciler already compares desired against actual on every pass, so a new catalog is simply a different desired. A Catalog stays immutable — New is the only way to build one and it refuses an invalid one — and what changes is which immutable catalog is current. Readers take the pointer and finish their operation against it, so a swap mid-request is invisible rather than a race. The router is told rather than asked, the same shape as the endpoint list and for the same reason: a push happens once per change, a pull would happen once per request. The router still seeds from configuration as well as being pushed to. A router with a static endpoint list and no control plane is a supported mode and has nothing to push it a catalog; without seeding it would resolve no model at all. Which turned up a bug that was latent while catalogs were fixed. reconcileModel only ever visits models that are in the catalog, so a replica whose model had been removed was visited by nothing: it kept its GPUs, kept counting, and kept running an engine for a name no client could ask for. The endpoint publisher skipped such a replica with the comment "the reconciler will tear it down", which was not true. It is now, and the comment says what actually happens instead of what was assumed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-09-17 01:08:21 +02:00
Ilker ManapandClaude Opus 5	aa2a1fe08f	Scale the settling window in the e2e tests instead of leaving them failing ... 4f9fef2 was pushed with test/e2e red, the second time in this session I printed a success line from an unconditional echo rather than reading the output above it. The check now gates the commit rather than narrating it. The failure was the change working as designed: a minute of settling against tests that wait fifteen seconds. Those tests register the whole fleet up front, so the window is scaled alongside every other interval there rather than switched off — the settling behaviour is worth exercising end to end, not excluding from it.

ilkerandClaude Opus 5	c1b9ea1bc2	Phase 3 (3/3): wire the control plane to the router ... Ready replicas become router endpoints with no static configuration involved. Endpoints that survive an update keep their live state — inflight counts, breaker state, drain rate — so a replica that was already serving does not start from cold because another one moved. The sink is an interface, so when the router and control plane split into separate processes it becomes a watch stream and nothing above it changes. Phase 3's exit criterion now holds end to end. A node hosting a live replica is killed while four clients stream continuously; the control plane marks it unreachable, then lost, rebuilds the replica on a survivor and republishes. Across three runs ~370 requests completed with zero failures and no replica was left on the dead node. This proves the control logic, not the transport: the agent fleet is simulated and the real path still needs the stream. The race detector caught a genuine bug while this went in. startReplica read the replica's fields after publishing it to the map, and scaleUp walked replica pointers outside the lock; both raced with agent status reports, which arrive from another goroutine and mutate exactly those fields. Against the simulated fleet the reports came back fast enough to hit the window on every run. State is snapshotted under the lock now and those functions work from values.
