Hew on SlOS — recorded supervised HTTP service
Verified 25 October 2026. Selected real-QEMU evidence, not a live service.

Provenance:
  Hew target/compiler: 95340fc
  Generic SlOS SDK/kernel: 04fcefa
  Hew-on-SlOS consumer: 2602e68
  Profile: O2 (--release)
  Gate: service-check, included in integration-final-o2.log
  Session: d7dd47b7ed274de899b20ac34c319bc5
  Sources: host.log and selected service.log output lines

The host harness checks exact HTTP response bytes. Its host.log records
status/body summaries below. Serial excerpts omit boot text, ANSI terminal
control sequences and incremental command echoes. Output order is preserved
within each source; the host and serial sources are displayed separately.
The second invocation uses a one-request budget.

HOST — original host.log:
notification b'ready\n'
notification b'timer sibling=101\n'
response 200 OK: 'worker=1 sibling=101\n'
response 200 OK: 'worker=2 sibling=101\n'
response 500 Internal Server Error: 'worker restarted\n'
response 200 OK: 'worker=1 sibling=101\n'
response 400 Bad Request: 'bounded ASCII headers required\n'
response 200 OK: 'stopping\n'
notification b'ready\n'
notification b'timer sibling=101\n'
response 200 OK: 'worker=1 sibling=101\n'

GUEST — selected service.log output:
supervised service listening :19080
supervised service stopped after 6 requests
status: PASS expected=0 actual=0
supervised service listening :19080
supervised service stopped after 1 requests
status: PASS expected=0 actual=0

Scope:
  Compiled Hew, cooperative local actors, one-for-one checked worker restart,
  fresh worker state, surviving sibling, independent timer during idle recv,
  bounded ASCII HTTP headers, graceful socket/supervisor cleanup.
  Serial single-connection diagnostic HTTP/1.0 example, not full std.net.http.
  No authentication or idle-client timeout. Crash/stop are diagnostic endpoints.
  Not full Rust-runtime/stdlib parity, full POSIX/libc, or a public Hew release.
