Problem

Discord users asked for broken Hub scripts to be hidden. The client already had upstream disable and minClientVersion, but there were gaps:

  • disable hid a plugin from every Hub user, including users who had it installed.
  • remove() refused disabled plugins, so they could not be uninstalled.
  • A Hub-level disable never stopped an installed jar, because the code for that (refresh()) is never called.
  • The update prompt pushed users to the latest version even when that version was the broken one.
  • Nothing could tell users why a plugin was broken, which versions were affected, where the issue was tracked, or the last build verified to work.

Change

Health metadata. Manifest entries can carry an optional health object, published by Microbot-Hub (companion PR: chsami/Microbot-Hub#576). Fields:

  • status: ok, broken or unverified
  • reason
  • affectedVersions: exact plugin version strings, with no ranges, or ["*"] for every version
  • trackingUrl: https only
  • lastVerifiedVersion, lastVerifiedClientVersion, updatedAt

Old manifests and old clients are unaffected. If one entry's health is malformed, only that entry is ignored.

Evaluation. MicrobotPluginHealth evaluates each version, highest priority first: DISABLED > INCOMPATIBLE > BROKEN > UNVERIFIED > VERIFIED > UNKNOWN.

Plugin Hub panel.

  • Badges: red ! for disabled, incompatible or confirmed broken; orange ? for unverified; green ✓ for verified.
  • Clicking a badge opens a details dialog: reason, affected versions, tracking link, and the last verified plugin and client. Missing values are labelled unknown or not provided.
  • Searchable keywords: broken, disabled, incompatible, unverified, verified.

Blocking and recovery.

  • Confirmed affected versions are refused at install and skipped at load, the same way disable works. Other versions stay installable.
  • A Hub-level disable now also skips installed jars at load.
  • Every skipped external jar is recorded with its reason. That covers a jar disable, a newer-client requirement, a Hub disable and a broken version. Recorded plugins stay visible in the Hub so users can remove them or pick an unaffected version.
  • Disabled plugins can be removed again. remove() now only stops a plugin loaded by that jar's classloader. Before this, removing the Hub ExamplePlugin matched the core ExamplePlugin and silently did nothing.
  • A blocked latest version no longer triggers the update arrow, the orange border or the "out of date" dialog.

Startup notice. After startup, one non-modal notice lists the plugins that were not loaded and why. It is not repeated for the same reason.

No guessing. Brokenness is never inferred from plugin age, and an unverified report never blocks.

Validation

  • New tests:
    • MicrobotPluginHealthTest (12): old/new manifests, healthy, incompatible, disabled, missing metadata, recovered, unverified, malformed, https-only.
    • MicrobotPluginManagerHealthTest (9): load skip and recording, notify once, update prompt suppressed, disabled plugin removable, same-named core plugin untouched.
    • MicrobotPluginListPanelNoticeTest (1).
  • Full :client:runUnitTests: 1968 tests, 0 failures.
  • Login-screen check on Xvfb with a local fixture manifest (temporary URL patch, reverted), using real Hub jars:
    • broken and disabled jars were blocked, still shown in the Hub, and removable;
    • all badges and dialogs appeared;
    • installing the unaffected 1.0.10 recovered the plugin; selecting the broken 1.0.12 was refused;
    • the startup notice appeared and did not block the client;
    • with the unmodified live manifest, the Hub looked unchanged.
  • Merges cleanly with fix(hub): order the New filter by addition date, newest first #1896 and fix(plugins): stop config toggle from disabling always-on plugins #1892.

Known gaps

  • Not tested while logged in, or on Windows/macOS. Replacing a jar after a blocked load on Windows depends on the classloader close, which is untested there.
  • Health is read once at startup, like the rest of the manifest.

Adds an optional, additive `health` object to Hub manifest entries
(status ok|broken|unverified, reason, affectedVersions, trackingUrl,
lastVerifiedVersion, lastVerifiedClientVersion, updatedAt), parsed
leniently so malformed metadata never breaks the manifest.

The Plugin Hub shows a badge and details dialog for disabled,
incompatible, confirmed broken, unverified and verified plugins, with
unknown values labelled honestly. Confirmed affected versions are
refused at install and skipped at load like upstream-disabled jars;
other versions stay installable. Installed but blocked or disabled
plugins stay visible in the Hub so users can remove them or pick an
unaffected version, removal of disabled plugins is allowed again, and
update prompts no longer point at a blocked latest version.

- A Hub-level disable now skips installed jars at load.
- Every external-jar skip (jar disable, newer client, Hub disable,
  confirmed broken version) is recorded with its reason, so the Hub
  keeps showing the plugin and it can be removed.
- remove() only stops a plugin loaded by that jar's classloader, so a
  same-named core plugin is no longer matched and removal completes.
- One non-modal notice lists blocked plugins and reasons after the
  plugin list is built.
- Tracking links must be https.
- Tests for load blocking, notice, update prompt and removal.

Walkthrough

The change adds health metadata and evaluation for external plugins. Plugin management uses health results and other block conditions during loading, installation, and update checks, and records blocked-plugin reasons. The Plugin Hub displays health status and details, while the plugin list panel can show a blocked-plugin notice. Tests cover health evaluation, manager behavior, and notice formatting.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to e37cc

A compatible older plugin version can be unavailable through the Hub when the latest version requires a newer client. This is a bounded version-selection issue; the PR is mergeable with owner awareness or a follow-up fix.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to e37cc

The change adds useful protection against known-broken plugins, but failed-removal recovery can discard installation state while leaving the old plugin registered. This can undermine removal and replacement guarantees within a client. No new remote execution privilege was established.

Retained concerns

  • Medium · reliability · inferred: Removal releases classloader ownership before shutdown succeeds. If shutdown throws, the plugin remains registered. A subsequent removal now skips that instance, deletes the JAR, clears installed-version state, and reports removal. Replacement loading can then skip the retained instance, and an enabled retained plugin can restart during profile refresh. The failed-stop ownership loss predates this PR, but deletion and successful-removal reporting on retry materially worsen recovery-state consistency.
Security review details

Security Blast Radius

  • inferred — Hub metadata can affect eligibility across clients consuming an entry, including every version through the wildcard. Plugin instantiation remains inside the client process; the retained recovery concern affects that client's plugin ownership and removal guarantees.

Security Findings and Attack Paths

  • inferred — A shutdown exception followed by removal retry can leave an enabled registered instance eligible for later restart despite artifact deletion. This is a conditional cleanup and control-drift concern, not a demonstrated new remote-code-execution vulnerability. Normal scheduling and event subscriptions are removed before shutdown is invoked.

Trust Boundaries and Controls

  • observed — Health is an eligibility policy, not authenticated artifact identity. HTTPS protects manifest transport, while the load gate uses name and descriptor metadata. Advisory hash-mismatch handling remains unchanged from the PR base. New health text is HTML-escaped, and tracking links require HTTPS and an explicit user choice.

Resilience and Maintainability Implications

  • observed — The classloader identity filter protects same-named plugins owned elsewhere. Tests cover this protection and disabled-plugin removal, but do not exercise successful removal through a real JAR loader or failed shutdown followed by retry.

Hardening Proposals

  • proposed — Retain recoverable classloader ownership until stop and deregistration complete. Distinguish an intentionally unloaded blocked artifact from a registered instance whose cleanup failed, and make retry reconcile runtime ownership before clearing installation state.

Apply the client-version gate to the selected version.

installSelectedVersion(version) checks manifest.getMinClientVersion() for every selection. This can block a healthy older jar whose descriptor supports the current client. The manager checks the selected jar’s descriptor.minClientVersion() during loading, so make this correction in the Hub path, not MicrobotPluginManager.install.

Suggested fix
-				if (!ensureHealthAllows(version) || !ensureClientVersionCompatible())
+				if (!ensureHealthAllows(version)
+					|| ((Strings.isNullOrEmpty(version) || version.trim().equals(manifest.getVersion()))
+						&& !ensureClientVersionCompatible()))
