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EventCapabilityUnavailable, ResolveRequest/ResolveResult (superseded by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.

Execution events (started/failed/succeeded) never carried the
correlation/causation IDs from the ExecuteRequest, even though the
fields existed on Execution. Added CausationID to ExecuteRequest and
Execution, and split emitEvent into a correlated variant used
throughout the execution lifecycle. handleExecute falls back to
X-Correlation-ID/X-Causation-ID headers when the body omits them.
Also add X-Hexis-Version negotiation on /api/v1/*, matching Nexus.
Part of Vikunja #273.
