Review fix round 1. Seven non-blocking findings; the blocking one is a merge gate for Task 4 rather than anything in this diff, and the report's concern about it is corrected: until Task 4 lands, PingNode probes two subjects no serve-backend worker subscribes to any more, so every healthy worker reads as absent and is marked unhealthy on the scheduling path. The rune-boundary cut in truncate was true behaviour with nothing holding it: a byte-wise mutation survived all 201 specs. isRuneStart is replaced by utf8.RuneStart, the same predicate the cluster package uses for this rule, and two specs pin it, one with a rune straddling the bound and one with a rune ending exactly on it so the fix cannot be "always walk back". unloadModel answered Success:true whatever Free did. That is the worker saying "done" about work it did not do, and the frontend's only caller is EvictLRU, so a false yes told the scheduler VRAM had been released and let it place the next model on a node still holding the old one. It now reports the failure, following stopModelExact, which is the honest pattern already in this package. Still a 200: the worker answered, only its verdict is negative. An address with nothing loaded still answers success, which is a true answer rather than a claim about work done. NewDebouncedInstallProgressPublisher had no production caller after the last commit, only its own spec. Deleted rather than wired: wiring it would publish every event on two carriers, which is what the carrier decision exists to avoid. Its specs now run against the sink, plus one that pins the identity stamped on each event, since the subject used to carry the op and node id and now nothing but the body does. The install progress wiring was exercised by no spec, because with no gallery nothing ever invokes the download callback. The guard moves into startProgress, shared by install and upgrade, which also emits one resolving event before any gallery work. That is worth having on its own: a cold install spends minutes on a manifest and a progress stream with nothing on it is indistinguishable from a broken one. It also makes the wiring observable end to end, and four specs now drive the real installBackend and upgradeBackend over HTTP with no override. model/stop and backend/stop keep taking Background rather than the caller's context, and the sites now say why. model/stop is the acknowledged stop path: it reserves the process, frees it, kills it, waits for exit and releases the port, and abandoning that because the caller hung up would leave a process marked stopping, a port not returned to the allocator and a row nothing reconciles. In stopBackendExact the Free is a courtesy before a kill that happens anyway. model/unload differs because Free IS the operation there. A route set with no prefix or no registrar is now a startup error rather than a silent no-op: a server that comes up healthy while every route the caller registered answers 404 is, through a tunnel, indistinguishable from a version skew. And the AllPaths spec no longer claims to catch a constant that was never added to the set, which it cannot; it asserts the whole set instead, which catches a verb dropped from it.
