Step 6: downstream_client() no longer sends X-Request-Id, and request_id
is gone from the internal request bodies, models, function signatures
and log lines; correlation now travels as traceparent. The gateway's
public request_id stays (the contract tests require it) but is now the
trace ID, 32 hex digits and still a valid UUID, so the value the
frontend shows can be pasted into Tempo.
Step 7: delete tests/test_no_observability.py. It guarded the Phase 0
"no observability" state, which Phase 3 ends by design.

81 tests across 11 files plus a 5-module harness (load, pg, streams,
containers, payloads), covering all eleven Phase 0 goals and all 13 named
chaos-flag pathologies. Talks to the system only over HTTP, Postgres, Redis,
and the Docker CLI -- no imports of application code. RED-BASELINE.md records
the suite failing red against the empty repo before any implementation
existed; README.md documents the request-contract fields invented to fill
gaps in the spec, measurement methodology, and known-flaky tests.
This suite is a frozen contract from this point forward per CLAUDE.md.
