Error 500 seems served by nginx itself, as PHP log is empty.
PHP log: /var/log/www/dereckson.be/zed51-php.log
nginx log: undefined, we should probably start by ensueing EACH vhost has its own log file

Thanks to D4057 we now have a direct nginx error log to parse:

There are several issues here:
- a clean way to co-develop in Keruald and Zed needs to be found, as Zed is one of the key application to battle-test Keruald libraries
- Zed seems to still use rKGF -> we're ready to redefine everything to be in omnitools directly
- libraries should be served from /var/51-wwwroot, but /var/51-wwwroot/zed/vendor/composer/../keruald resolves to /home/dereckson/dev/keruald/_monorepo/core (which satisfies the need to develop Keruald)
- there is no globalfunctions/ folder in our Keruald development directory
This issue has probably been introduced symlinking in vendor folder keruald/ to the Keruald monorepo:
$ pwd /var/51-wwwroot/zed/vendor $ file keruald keruald: symbolic link to /home/dereckson/dev/keruald/_monorepo/core
A clean way would be to symlink to /var/51-wwwroot/keruald
That makes sense to move _monorepo/core there as that folder is intended to serve web applications and supporting libraries: if Keruald is developed not only for CLI applications / pure libraries unit tests but also for web applications, it really needs to live in /var/51-wwwroot (same issue than for mediawiki).
That won't solve the globalfunctions issue, so I'd suggest a two step config:
(1) recreate keruald as directory, symlink needed libraries from keruald here + clone rKGF
(2) after globalfunctions isn't needed, keruald -> /var/51-wwwroot/keruald

First step of the plan is done.
Next bag of issues: configure local MariaDB
2026/04/13 13:23:53 [error] 97670#103960: *319791 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught mysqli_sql_exception: Access denied for user 'zed'@'localhost' (using password: YES) in /var/51-wwwroot/keruald/database/src/Engines/MySQLiEngine.php:56
Issue 1 is obvious: we need to ensure we've a local Zed database.
Issue 2 is the existence of start.html file from old laptop development/demo to invite to start MySQL server. It was the page to use in the past if we couldn't connect to database. Current code doesn't seem to refer to it anymore. We can prune it.
Issue 3 is the services registration code: we have no error handling when a service can't be created.
____
After creating the database with a combo of dev/schema-mysql.sql + doc/database/migrations/001_allow_longer_password_hashes/up.sql + dev/test_content.sql, the following issues remain:
(1) update keys to ensure 1000 bytes key max (varchar 255 is too big, as utf8mb4 can use up to 4 bytes): perso flags can be InnoDB, content_locations can reduce location_local to 240
(2) user_actkey tries to import NULL in dev/test_content.sql, code expects ""
Finally, we're in a "normal" error for the migration of the library code to Keruald:

We've a last nginx fix to apply to simplify the configuration, and we'll be good to close this task.
