 - Frequency: deterministic (by code reading; confirmed by the RED test of the fix)
 - Evidence: the code sites quoted in Description; no logs kept.
 ## Root cause
-TODO: required for fixed/partial
+`validateHost` (`controllers/hosts.go`) wrote a 403 via `ReturnError` without aborting, so `ControlHost`'s `IsAborted()` check never fired and it wrote a second (202) response. Pre-existing.
 
 ## Fix
-TODO: required for fixed/partial
+`validateHost` no longer writes a response: it checks `host:control` once, before the host loop (it used to check per host and not at all for an empty list), and returns an error; `ControlHost` writes a single 403 and returns; for `all` the host list is resolved first.
 
 ## Verification
-- Test: TODO: name + file; RED before the fix, GREEN after
-- Suites: TODO: suite results and build profile
-- Live: TODO: soak/deploy run, or n/a and why
+- Test: `TestControlHost_RejectedWritesSingleResponse` (`controllers/hosts_handler_test.go`, route without its guard): RED `hosts_handler_test.go:61: handler wrote 2 responses, want 1`, GREEN after.
+- Suites: `xce-build.sh all asan xce.build --incremental` on the merged branch, 2026-10-10: C suites Ok 157 / Fail 0; frontend Go tests ok (the build now also runs apiserver cmd, middleware, models and router)
+- Live: n/a: unit/fixture-level verification; no live deployment was run
