clawbot	c247f6bcf5	watcher: notify nameserver address changes (closes #105) ... Each domain check now looks up the addresses every nameserver's name resolves to, with the resolver's ResolveIPAddresses, and saves them sorted in the domain's state. A nameserver that stays in the delegation and resolves to different addresses sends one NS Address Change notification naming the domain, the nameserver and the old and new addresses. Added or removed nameservers get only the NS change notification. A failed or empty lookup keeps the previous addresses, because the resolver returns no address without an error when every server it asks times out. State files without the field load, and the next check fills it in silently. Watcher tests that run domain checks use example.com, which has two nameservers, to stay within the per-attempt limit.

clawbot	8f11ef0038	watcher: notify NS query failure and recovery (closes #104) ... LookupAllRecords now returns each nameserver's response, so the watcher saves its status: ok when it answered, NXDOMAIN and no records included, and error with the reason when it timed out, answered SERVFAIL or REFUSED, or could not be reached. A nameserver that starts failing sends NS Failure and one that answers again sends NS Recovery. A failing nameserver is left out of the record change and inconsistency comparisons. The resolver used to report REFUSED and network errors as an answer with no records; they are now errors. A lookup cut short by its context now returns an error instead of a failure of the nameserver it was querying. Model: opus-5-5	2026-10-01 22:23:33 +02:00
clawbot	db94c903df	tests: move the test-only constructors into export_test.go (closes #111) ... state.NewForTest, state.NewForTestWithDataDir and watcher.NewForTest were compiled into and exported by the production packages internal/state and internal/watcher. NewForTestWithDataDir and watcher.NewForTest now live in their package's export_test.go. Tests in other packages cannot see those files, so the watcher and middleware tests build their State with state.New and a temporary data directory; the watcher tests no longer try to save to /state.json. state.NewForTest, whose State saved to /, is deleted: the state tests that used it pass t.TempDir() to NewForTestWithDataDir, and the test of the helper itself is gone.

clawbot	a93389e1a0	watcher: send the inconsistency alert once per disagreement (closes #158) ... detectInconsistencies alerted for neighbouring pairs of nameservers whose records differed, on every DNS check, for as long as they differed. It now also takes the previous hostname state, compares every pair of nameservers, and alerts for a pair that differs unless both were in that state and already differed there, so a nameserver new on a check that answers differently is reported once. The state loaded at startup is the previous state for the first check, so a disagreement saved before a restart is not reported again. The choice of pairs is tested on record data, and the alert through the hostname change detection with the notifier stand-in and no resolver. The README describes the new behaviour.
