| `Config::set_host_plugin_basename( plugin_basename( __FILE__ ) )` is optional and matters only on | ||
| multisite. It lets the library compare your plugin's activation scope against a standalone's, so it | ||
| declines to deactivate a network-active standalone when your plugin is not itself network-activated | ||
| — a deactivation that would otherwise pull the standalone from the network's other sites, where your | ||
| bundled copy never loads. Left unset, that guard stays off and deactivation behaves as it always has. |

Having this be optional has me skeptical. Even if we may not officially support multisite in some cases, allowing things to potentially break because we didn't make an optional config required doesn't sit right with me.

Do not document the multisite guard as active yet.
Config::set_host_plugin_basename() stores the value, but no current consumer uses it to change deactivation behavior. This text promises protection for network-active standalone plugins and incorrectly describes the setter as a no-op off a network. Describe the setting as preparation for the follow-up guard, or include that consumer in this change.

This is part of a set of stacked PRs. It is used in followup PRs.

@d4mation, thanks for the clarification. The configuration is consumed by the follow-up pull requests in this stack. The README describes the completed stacked behavior. I withdraw this finding.

Learning: In the Plugin Absorber change stack, the pull request that adds `Nexcess\PluginAbsorber\Config::set_host_plugin_basename()` stores configuration for multisite guard behavior implemented and consumed by follow-up pull requests. Review documentation for this setting in the context of the full stacked change, not this configuration pull request in isolation.

@coderabbitai This doesn't need to be a learning. If you want to add a learning, it should be to check to see if a given PR is part of a GitHub Stack and check to see if something is consumed in a later stack.

@d4mation, thanks for the guidance. The prior PR-specific learning is unnecessary.
I cannot remove that learning here because its UUID is not available. You can delete it from the CodeRabbit learnings page.

Learning: When reviewing a pull request in a GitHub Stack, check the Change Stack context and related later pull requests before reporting that a new API or configuration value has no consumer. A later pull request can provide the consumer or behavior that the current pull request documents.

@nikolaystrikhar You may want to go into CodeRabbit's dashboard and clean up some Learnings it made for this PR stack. It looks like stacking PRs may confuse CodeRabbit 🫠
We may need to add something like this as a general Review Instruction.

What: Add optional
Config::set_host_plugin_basename()/get_host_plugin_basename()— the host fact the multisite stranding guard (later in this stack) reads. Nothing consumes it yet.Usage:
Why this way:
Optional, with a non-throwing getter. Unlike the hook prefix and the container, an unset basename is a valid state — it stands the multisite guard down — so
get_host_plugin_basename()returns''rather than throwing the way the other two accessors do.Stored verbatim, not through the hook-prefix validator. A basename is a path (
dir/file.php), and the prefix validator rejects/and., so reusing it would reject every real basename.Config_State::DEFAULTSgains the new static too, so the suite's reset stays exhaustive (it throws on any unknown static).No caller yet, on purpose. This is the config surface only; the checker, the notice, and the guard that reads all three arrive in the next PRs, keeping each one under the source-file cap.
