#!/usr/bin/env bash
# USE CASE: a SECOND foreground `start -c` (separate config) streams ITS OWN logs.
#
# WHAT THIS TESTS (real dogfooding bug)
#   term1: `sysg start -c alpha.yaml` (foreground) — owns the shared control
#   socket and streams alpha's logs. term2: `sysg start -c beta.yaml`
#   (foreground, DIFFERENT config) registers beta into the same supervisor AND
#   must stream BETA's logs to term2. In 0.54.2/0.55.0 the second foreground
#   start was silently ABSORBED: it registered beta but streamed nothing, so
#   term2 sat on a spinner with no output. Contract: each foreground terminal
#   follows its OWN project.
#
# EXPECTED OUTCOME
#   - alpha's captured output contains ALPHA_MARKER_LINE.
#   - beta's  captured output contains BETA_MARKER_LINE  (the bug: it was empty).
#   - neither terminal is cross-contaminated with the other's marker.
