From 9e6b99553804d02c1e3be9b64d5d0079e6142a1c Mon Sep 17 00:00:00 2001 From: kami Date: Thu, 30 Jul 2026 23:40:04 +0400 Subject: [PATCH] Remove dead code and three tests that assert nothing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Finding 5 and the "remove" list of REVIEW-2026-07-30.md. The tests were prose, not verification. TestContract_ChangesSinceAlwaysZero documented a bug commit 74b19e0 had already fixed and could only t.Logf. TestContract_TimeoutGoroutineNotCancelled was a bare t.Log, and is now falsified by the preceding commit anyway. TestContract_DestructiveCapabilityDisabledByDefault re-implemented `risk != "destructive"` inside the test and asserted on its own local variable — it would have passed if the handler were deleted. The real derivation is now domain.EnabledForRisk and is tested against production code. Also removed: the systemd provider (no systemctl in the distroless image and nothing ever registered it), Server.ListenUnix, Registry.List, DiscoveredTools, Capability.IsDestructive, the ExecutionDenied status, EventCapabilityUnavailable, ResolveRequest/ResolveResult (superseded by nexusclient), Engine.emitEvent, and eight unused Err values. Three items on the review's list were kept, having turned out to be wrong: ifString is still used by BuildCapabilities; EventExecutionDenied is asserted on by a real test; and schema_migrations was NOT dropped. migrate() applies migrations by slice index and writes user_version = index + 1, so removing an element renumbers every later migration and any database past that point would permanently skip one it had not yet applied. The live database is far behind HEAD, so that is a data hazard rather than a cleanup. The CREATE TABLE is now a no-op holding its slot, with a comment saying why the slot must stay.
