test-stack-up.sh: an app started by mxcli run --local always reads APP_OWNERSHIP=unverified, so journey-runner refuses the documented local loop #160

What happens

project-bin/test-stack-up.sh proves that a serving port is this project's only one way: through a Docker container under <project>/.docker (owned_app_port, ~l.131; find_app_port, ~l.161-177). An app started by mxcli run --local is the documented local loop, and it has no such container. The port is found by scan and recorded as APP_OWNERSHIP=unverified in stack.env. The harness then refuses it unless the port is asserted by hand (ALLOW_UNVERIFIED_APP=1 / APP_PORT=…), on every run.

Evidence (card-disbursement requirements-driven build, 2026-09-25)

• Every journey run in the project needed APP_PORT=8080 asserted by hand. There is a register ruling for it.
• The proof of ownership was available all along. The runtime's java process runs runtimelauncher.jar <project>/app/deployment (read from /proc/<pid>/cmdline), which names this project's own deployment directory.

Suggested fix

In find_app_port (or owned_app_port), after the container check, accept a second proof:

1. Find the PID listening on the candidate port:
   • Linux: ss -ltnp or /proc/net/tcp → inode → /proc/*/fd;
   • macOS: lsof -nP -iTCP:<port> -sTCP:LISTEN.
2. Read its command line:
   • Linux: /proc/<pid>/cmdline;
   • macOS/Git Bash: ps -o args= -p <pid>.
3. Record APP_OWNERSHIP=verified only when the command line runs runtimelauncher.jar and its argument resolves (realpath) to this project's deployment directory. Check both layouts: <root>/deployment and <root>/app/deployment on a two-tree checkout.
4. Otherwise it stays unverified, as today.

Filed rather than fixed because the field-proof bar needs a run against a live run --local app on each platform. test-stack-up.sh also probes the port over HTTP, which could not be done against the field app from this session.
