Closes #142

What

• PluginStore, with Records, Activate and Pause, is the application's record of each plugin's state between boots: not installed, inactive, active or paused, with the text of the failure that paused it. The application implements it over its own tables.
• NewBoot reads every record once. Register records a plugin it has never seen as active, registers the active and paused plugins through RegisterEach, never registers inactive or not installed ones, and pauses each plugin that fails to register.
• Boot.Pause pauses a plugin for a reason of the application's own. Boot.Started pauses each plugin that failed to migrate or start, leaves a failed migration record alone because that plugin still started, and activates each paused plugin that started again, clearing its error.
• A boot whose context ends, while plugins register or start, pauses nothing and returns the context's error. A store read or write that fails is returned, as pluginkit: read the plugin records: ..., pluginkit: pause feed: ... or pluginkit: activate feed: .... A boot where nothing changes writes nothing.
• pluginstoretest.Run checks any store against the contract, and pluginstoretest.NewMemory is a store in memory that keeps it.
• The behaviour is written as scenarios in pluginkit/features/boot.feature.

Why

A downstream application must keep serving when one of its plugins fails at boot, show that plugin as paused with its error, as WordPress's recovery mode does, and try it again at the next start, while a plugin turned off on purpose stays off.

Testing

• go test -race -shuffle=on passes for pluginkit, pluginkit/pluginstoretest and pluginkit/wire, and coverage stays at 100%.
• 16 scenarios with 97 steps pass in boot.feature, beside the hook, screen and registration scenarios, 20 times in a row under -race. Breaking each boot rule on purpose fails the scenarios that describe it.
• The contract suite's own checks are tested with a recording testing.TB, so their failure paths are covered too.
• Mutation testing killed all 18 mutants in the new code.
• CodeScene scores 10.0 on every new and changed Go file.

Walkthrough

The PR adds plugin state records and a store interface, then uses them to coordinate registration and startup. Boot failures can pause plugins while other eligible plugins continue. Paused plugins are retried on later boots. The PR also adds an in-memory store and tests for the store contract and boot behavior.

Changes: Plugin state and boot flow

Layer / File(s)	Summary
Plugin state contract and test store pluginkit/pluginstore.go, pluginkit/pluginstoretest/*	Defines plugin states, records, and store operations. Adds a reusable contract test runner and a mutex-protected in-memory store with tests.
Boot registration and startup coordination pluginkit/boot.go, pluginkit/boot_test.go	Adds boot-time record loading, registration eligibility, pausing for eligible failures, and activation of paused plugins that start successfully. Tests cover store errors, context cancellation, and unchanged state.
Boot scenarios and validation pluginkit/features/boot.feature, pluginkit/features/features_test.go, pluginkit/features/steps_boot_test.go, pluginkit/CHANGELOG.md	Adds Gherkin scenarios and a test harness for registration, startup, retries, context cancellation, and store failures. Documents the new behavior and store test package.

Full details: Title check

Explanation

The title names the main change: plugin state persistence (keeping each plugin's state) and pausing a plugin that fails at boot. The changeset adds PluginState/PluginRecord/PluginStore, Boot with NewBoot, Register, Started, and Pause, and the boot tests and feature scenarios that pause failing plugins. The title is specific, follows the conventional commit form, and its length (79 characters) is acceptable. It omits the Gherkin feature, the pluginstoretest contract runner, and the in-memory store, which is expected for a short title.

Full details: Linked Issues check

Explanation

Directly linked issue #142 has coding requirements only. Each requirement maps to code at the reviewed head:

• PluginState, PluginRecord, PluginStore (pluginkit/pluginstore.go): four states (not installed, inactive, active, paused), a record with ID, State and LastError, and an interface with Records, Activate and Pause. Matches #142.
• NewBoot (pluginkit/boot.go): reads records once through store.Records. Matches #142.
• Register: admit() records unseen plugins active via activate(). Active and paused plugins are kept; inactive and not-installed plugins are dropped. The kept entries go through RegisterEach. pauseEach() pauses each failure with failure.Err text. Matches #142.
• Boot.Pause: pauses with the application's reason text through the store. Matches #142.
• Boot.Started: rejects an ended context before any write. pauseEach() pauses each failed migration or start. Failures at StepRecord are skipped, and the code comment states these are failed migration records of plugins that still started. Activate() is called for each started plugin whose stored state is paused, which clears the error per the PluginStore contract. Matches #142.
• Store errors are returned with the operation name through guarded(), for example 'pluginkit: pause feed: ...'.
• pluginstoretest.Run (contract suite) and pluginstoretest.NewMemory (memory store) are present, with tests in check_test.go and memory_test.go.
• Gherkin scenarios are in pluginkit/features/boot.feature, run by TestBoot, with step support in steps_boot_test.go.

Residual uncertainty: the context check for Register and Boot.Pause depends on guarded(), which is defined outside the reviewed boot.go excerpt and was not inspected. Only Started's ended-context check is visible in boot.go. The feature summary reports an ended-context scenario for pause writes. No concrete unmet requirement is shown.

RegisterEach only emits StepRegister failures, so the StepRecord skip in pauseEach does not change Register behaviour.

Not a #142 requirement: a paused plugin that fails again at boot is paused again, which writes. This does not conflict with #142.

Full details: Out of Scope Changes check

Explanation

Every changed area maps to an objective in #142 or supports one:

• pluginkit/pluginstore.go: PluginState, PluginRecord and PluginStore (#142 item 1).
• pluginkit/boot.go: NewBoot, Register, Boot.Pause and Boot.Started (#142 items 2 and 3).
• pluginkit/boot_test.go and pluginkit/features/* (boot scenarios and steps): tests and Gherkin scenarios that #142 requests.
• pluginkit/pluginstoretest/*: contract suite and memory store (#142 store contract item).
• pluginkit/CHANGELOG.md: documentation of the new behaviour, which supports the change.

No change in the summary is unrelated to #142. Ignored files were none, so no exclusion affects this result. The whole-PR diff was taken from the merge base to the reviewed head, and the summary matches the files present at the head.

Full details: Docstring Coverage

Explanation

Docstring coverage is 57.14% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 21 functions across 8 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

[Medium impact] The PR appears safe to merge; all three previous findings are fixed and no new actionable issues were found.

Summary

Adds saved plugin states and a boot flow that pauses failed plugins and retries paused plugins on the next boot.

• Plugin boots now follow saved states and pause plugins that fail.
• Plugin stores now share a contract for saved states and failures.
