Must-use diagnostics

MU Plugin Rescue

Use this recovery path when normal BarkBowl REST diagnostics return internal errors or when an active plugin failure may be stopping the request before diagnostics can answer.

Helper target 1.29.0 wp-content/mu-plugins

Step 1

Copy the helper.

From the source package, copy ops/mu-plugins/barkbowl-emergency-diagnostics-v1.29.0.php to wp-content/mu-plugins/barkbowl-emergency-diagnostics.php.

Step 2

Open the direct MU beacon.

The direct beacon exits before normal active plugins load, so it can answer even when the normal BarkBowl plugin has a fatal error.

Open MU ping

Step 3

Then test normal BarkBowl.

If the MU helper passes, install the normal plugin/theme, run the seeder twice, save permalinks, clear caches, then test /wp-json/barkbowl/v1/ping.

Copyable check order

/barkbowl-mu-ping.json
/barkbowl-mu-diagnostics.json
/?barkbowl_mu_ping=1
/wp-json/barkbowl/v1/mu/ping
/wp-json/barkbowl/v1/ping
/wp-json/barkbowl/v1/diagnostics/lite

Boundary: MU diagnostics are public-safe smoke signals. They do not approve releases, validate credentials, probe private networks, train models, or replace human review.
