UPDATE: I am not going to continue to troubleshoot this. Composer is working OK in my local site, so I'm going to change my approach to deployment and stop running composer in my staging site. Instead I will run composer locally, commit core & vendor to the git project, and deploy all code to staging with git.
I am trying to get my permissions right, so I don't have to run composer as root. As part of this process, I deleted vendor, core and composer.lock and ran composer install with my non-root user. The site appears to be working fine, despite this message composer displayed:
Problem 1
- drupal/core 8.2.x-dev requires symfony/psr-http-message-bridge v0.2 -> satisfiable by symfony/psr-http-message-bridge[v0.2] but these conflict with your requirements or minimum-stability.

- don't install drupal/core-render 8.2.6|remove drupal/drupal dev-master
- don't install drupal/core-render 8.2.7|remove drupal/drupal dev-master
etcetera
What does this mean? Is my site OK, or did I take a wrong turn?
I'm not sure why the composer message references "drupal/core 8.2.x-dev". Here is the "require" section of my composer.json:

composer why-not drupal/core:8.6.13lists? This may narrow the problem down better. As a side note, I suspect there is a Symfony related dependency problem. Personally I always usewebflo/drupal-core-strict, pinned top the same version as core, which tends to prevent dependency problems.
