Was 7/16 of tools/testserver/README.md's mode table covered by engine_test.cpp. Adds the rest: - engine_expiring_signed_url_recovers_via_refresh_url: an expired signed URL 403s, the engine asks (paused, decision_calls >= 1) rather than failing terminally, and DownloadHandle::refresh_url() with a freshly signed URL completes it -- exercises both do_refresh_url() fixes and the probe-level referrer retry's second-403 path from the previous commit. - engine_403_without_referer_retries_with_origin: no spec.referrer set, the automatic single retry (previous commit) recovers with zero decisions asked. - engine_redirect_chain_follows_to_completion: 5 hops of a plain 302. No core-side change needed -- documents that CURLOPT_FOLLOWLOCATION/ MAXREDIRS (already on, RequestOptions::follow_redirects) cover both the probe's and every worker's own request, not just one of the two. - engine_slow_loris_stall_timeout_fires: proves curl's stall detector (CURLOPT_LOW_SPEED_LIMIT/_TIME, download_task.cpp's hardcoded 1024 B/s for 30s) actually fires rather than hanging. Needed a real fix, not just a test: every other test in this file relies on TestServer's short 1s loris dribble to keep runtime down, but 1s of trickle followed by full-speed streaming never accumulates curl's required 30 CONSECUTIVE seconds under the floor, so it would never actually abort -- a test built on the default dribble would pass by the download merely finishing a bit late, not by observing the stall timeout fire. testserver_fixture.hpp's TestServer gained an explicit-loris-seconds constructor (default ctor unchanged, still 1s) so this one test can ask for a dribble (40s) that genuinely outlasts the threshold. - engine_401_digest_then_provide_auth_completes: same shape as the existing 401-basic test: http_client.cpp already asks libcurl for CURLAUTH_ANY regardless of net::AuthScheme, so this needed no core change -- it passed on the first run and is here to prove that's true end-to-end, not just at the http_client unit level. - engine_chunked_no_length_completes_single_segment: Transfer-Encoding: chunked, no Content-Length anywhere (including HEAD). No core change needed -- takes the same size-agnostic "unknown size, one plain-GET segment" path as the existing no-range test. - utf8/legacy-content-disposition: already covered end-to-end by probe_reads_utf8_content_disposition and probe_reads_legacy_content_disposition in probe_test.cpp (probe-level, as these modes only affect the initial request) -- verified passing, no new test needed. All 20 engine_test.cpp cases and all 10 probe_test.cpp cases pass. Every testserver.py spawned while writing and running this was reaped by TestServer's destructor; verified no stragglers with `ps aux` after each run.
