feat(server): install plugins from npm with integrity checks and staged updates by saphid · Pull Request #16054 · pingdotgg/t3code

saphid · 2026-10-05T12:08:33Z

Stacked on #16053 (and #15010). Review only the top 12 commits: fec5fa9.

Rebased 2026-10-10 onto #15010's current head (1fe8efd69a, on main 57b3780). The npm handlers are registered in main's instrumentation map instead of observing themselves. Installing and updating from npm stays on access:write, and the scope test also expects main's requiredPermission field. The follow-up commits in this PR answer review-bot and review findings, each with a focused test; GPT-6.1 Sol (high) reviewed them in two rounds: SHIP. Main moved the host process references into a HostProcess module (#17641), so the npm install test provides the process arguments through HostProcess.Arguments. The commit that types WebSocket handlers against the plain RPC group moved down to the plugin views layer, because main's newer WebSocket methods hit the type checker's instantiation limit one layer earlier. Two new commits end this layer. The tarball reader now reads a prefix only from POSIX headers, not GNU ones, treats a directory's size as reserved space rather than data, and refuses a global header that sets a path or size. A staged update's summary now comes from the catalogue's summarizer, so it lists tools, settings, and actions too. A further commit ends this layer: the tarball reader now refuses a pax record whose last byte is not a newline, so a malformed record can no longer rename the file that follows it. Four further commits end this layer. The tarball reader sizes a GNU long-name record by its own header and refuses a path with a NUL byte. Applying an update now reports the installed new version when only re-enabling the plugin failed, and refuses an update whose files are the ones already installed, which a restart mid-swap could otherwise lose. GPT-6.1 Sol (high) reviewed this port: SHIP. Bot reviews later found three npm tarball header bugs (PAX global headers, directory sizes, GNU magic) and a staged-update summary that left out tools, settings and actions; "fix(server): read npm tarball headers the way tar writers mean them" and "fix(server): list a staged npm update's tools, settings, and actions" fix them, with tests that fail without the fixes (GPT-6.1 Sol (high): SHIP). "fix(server): size the npm unpack cap by archive entries, not files" stops valid archives with directories or extended headers being refused as too large. "fix(server): refuse a pax record that does not end in a newline" rejects a malformed extended header that could rename the next file. "refactor(server): follow the Effect service rules in npm plugin installs" applies main's service rules (namespace service import, errors built where they happen, causes kept). Four fixes from review: GNU long names sized by their own header, NUL bytes refused in tarball paths, an update that applied but could not re-enable the plugin reported as applied, and an update to the already-installed files refused instead of removing the package. A test-only change in the first commit: the two "disable was cut short" tests no longer wait on a file watch, which macOS could miss under load and hang the test. The test plugin now waits on a local socket the test answers. The full npm test file passed 30 of 30 runs under CPU load at this layer and at the top of the stack. Captures below were taken at the revisions they name. At this head (fec5fa9cfd) these pass: focused tests (12 files, 145 tests), typecheck (t3, @t3tools/contracts), lint and fmt on the changed files, knip.

Problem

Plugins can only be added from a directory already on the server's disk. To share a plugin, an author has to tell people to clone or copy files by hand, and there is no safe way to update one: overwriting the directory changes the bytes under a running plugin and drops its consent.

This PR lets an administrator install a plugin from an npm registry, and update it in two steps: stage the new version, review it, then approve and apply it. Installing and updating run nothing; the catalogue still needs consent to the exact unpacked files before a plugin can be enabled. Nothing changes in the web, desktop or mobile UI yet.

Why this qualifies

This is the proposal route in CONTRIBUTING, and no maintainer has agreed to it yet. It needs #6714 (plugin distribution / marketplace), on top of the plugin-system approval the plugin host PR needs on #6714 / #6837.

It stacks on the plugin views PR. It uses only the plugin host (catalogue, consent, supervised children); the dependency on the layers between is ordering. No client calls these RPCs in this PR. The install and update buttons arrive with the plugin management UI PR; until then they are reachable from an administrative connection (the evidence uses a script). We recommend reviewing this together with that UI PR. If the answer is no, we close this and the plugin PRs above it. Previous PR in this stack: feat: show plugin views as isolated right-panel tabs on web and desktop (#16053).

Fix

RPCs, registered in the RPC scope middleware like every other method, and gated on a new optional pluginNpm environment capability so clients never call an older server:

Method	Does	Scope
`plugins.npm.list`	installed npm packages, with any staged update	`orchestration:read`
`plugins.npm.add({ name, version, registry? })`	resolves, verifies, unpacks, adds to the catalogue as `needs-consent`; runs nothing	`access:write`
`plugins.npm.stageUpdate({ installationId, version })`	downloads and checks a version next to the installed one, which keeps running	`access:write`
`plugins.npm.applyUpdate({ installationId, digest })`	consents to the staged digest and swaps it in; puts the old version back on failure	`access:write`
`plugins.npm.discardUpdate({ installationId })`	deletes the staged files	`access:write`

Removal is the existing plugins.remove; the server then deletes the downloaded files once the plugin has stopped.

Layout. Each package lives under <state>/plugins/npm/<key>/: package/ is the catalogue installation's directory (same path across updates), npm.json records where it came from, .staging-* holds a download in progress or a staged update, and .previous exists only while an update is applied.

Applying an update journals the swap in npm.json, then runs one catalogue step (PluginCatalog.replace, new and server-internal) under the catalogue's management lock: disable, wait for the process to exit, rename package → .previous and staged → package, re-digest, and consent to the reviewed digest. That consent is the commit point; a failure before it restores .previous and the old consent still applies. If the plugin was enabled it restarts on the new version with a new generation, so calls in flight on the old one can never reach the new bytes. A swap a crash interrupted is finished (if the catalogue already holds the new consent) or rolled back at the next start, and the installation is left disabled.

One rule for file moves. Every move or deletion of plugin files under the npm root goes through one of three catalogue steps (replace, settleReplace, changeFiles). Each claims its paths under the management lock: it is refused while any other installation is rooted in or around them, and it waits until every process that ran from those files has actually exited, even if the disable that stopped it was interrupted. A deletion that is refused or fails stays queued and is retried before every npm step, after every catalogue change, and at startup. The one exception is the provenance record npm.json beside package/, written whole by temp-file-and-rename under the npm lock.

Size: 20 files, +4076 / −5. About 2.45k of the added lines are tests and the tarball test kit; production is about 1.6k (server ~1.4k, contracts ~0.2k).

Security: supply chain

Who can install: only administrative sessions (access:write). A standard pairing can list packages and is refused for every mutation, through the same middleware as the other plugin management RPCs.
Nothing runs on install or update. No npm, no package scripts, no require. A package with a preinstall, install or postinstall script, or a native build (binding.gyp), is refused (npm-install-scripts). Dependencies are never installed: every runtime dependency (and each of theirs, by Node's lookup, never above the package root) must be bundled inside the package (npm-dependencies). The plugin then needs consent and an enable like any other plugin.
Integrity. The registry must publish a sha512 SRI value for the resolved version, or the install fails (npm-integrity-missing); sha1 shasum is not accepted. The downloaded tarball must hash to it, or the install fails (npm-integrity-mismatch) and nothing is written. Only the exact resolved version and its integrity are stored, never a range or tag; ranges are refused by the schema. This protects against a tampered tarball host or transport. It does not protect against a compromised registry or a malicious publish, which can publish matching integrity for bad bytes; that is what consent to the unpacked digest is for. Signatures and provenance attestations are not checked.
Registry. The default is the public npm registry, kept as one server constant. An administrator may name another registry as an http/https URL; credentials, queries and fragments are refused, and no .npmrc or auth helper is read. The registry response's name must match the request, and its version must be exact (and equal the request when the request was exact). The tarball URL may be any http(s) URL, because the integrity covers the bytes. Requests go out from the server with the server's network access; only administrators can trigger them.
Extraction limits. Metadata ≤ 1 MiB (30 s timeout). Tarball ≤ 32 MiB compressed, counted while streaming (120 s timeout). The archive is parsed in memory, linear in its inflated size: ≤ 40,000 tar headers of any kind, each path ≤ 1,024 bytes and ≤ 64 segments, pax/GNU long-name headers ≤ 64 KiB, and the unpacked package ≤ 10,000 files / 64 MiB (the catalogue's own caps).
Path traversal. The whole archive is checked before anything is written. Only regular files and directories under package/ are accepted; links, devices, absolute paths, .. segments, colons (which would name a hidden NTFS stream the consent digest cannot see) and anything that leaves the package root are refused (npm-archive-unsafe). Files are written with wx into a fresh mkdtemp staging directory, so nothing outside it can be created, followed or replaced.
Package checks. package.json must exist with the resolved name and version (npm-package-mismatch). The catalogue validates t3-plugin.json as usual. A new version must keep the same plugin id (npm-plugin-id-changed).
Consent is required again on update. applyUpdate takes the digest the administrator was shown; it must equal the staged digest, and the staged files are re-digested before the swap and again after it. The catalogue then holds consent to the new digest only: the old digest is refused (source-changed), so a stale consent can never enable new bytes.
Trust model. Unchanged from the plugin host PR: a consented, enabled plugin is trusted local code running as the server's user. A dynamic require of something outside the package is not caught by the dependency check.

Evidence

Environment: macOS arm64; this PR on top of the plugin views PR. Tests use an in-memory registry (a mocked HTTP client serving generated tarballs); no test touches the network.

How to exercise it (isolated vp run dev, an administrative session and a standard pairing): from the administrative session, plugins.npm.add a tiny plugin package (a local registry fixture or a real small package), see it needs-consent in plugins.list, consent and enable it; stageUpdate a newer version, applyUpdate with its digest, and see the old digest refused by plugins.consent. From the standard pairing, plugins.npm.list works and plugins.npm.add is refused.

Live trace at this head (isolated server on a fresh home, macOS 26 arm64, Node 24; an administrative session and a standard pairing; a local registry on 127.0.0.1 named through the registry input, so nothing touched the public registry). The test package has one action that reports which version is running, records each activation, and carries prepare and test scripts that would leave a marker if anything ran them.

	Plugin views PR (parent)	This PR
`capabilities.pluginNpm`	absent	`true`
`plugins.npm.*` (all five, administrative session)	`Unknown request tag`	served, scope-checked

What the trace shows, in order:

Install: plugins.npm.add with the latest tag resolves to exact 1.0.0 and returns the installation as needs-consent with its digest. No plugin process starts and no script runs.
Refused installs, each leaving the package directory unchanged: a tarball whose bytes differ from the published sha512 (npm-integrity-mismatch, "Nothing was installed."), a tarball with the entry package/payload:code.mjs (npm-archive-unsafe, "has a colon in its path"), and a package with a postinstall script (npm-install-scripts).
Consent and enable with the shown digest. The action answers proof.npm 1.0.0 running.
Standard pairing: plugins.npm.list works. add, stageUpdate, applyUpdate, discardUpdate and plugins.remove are each refused with requiredScope=access:write.
Stage, discard and stage again: staging 1.1.0 shows its manifest and a new digest while the plugin still answers 1.0.0. Discarding deletes the staged files.
Approve the update again: applyUpdate with the old digest is refused (source-changed) and 1.0.0 keeps running. With the staged digest the installation moves to 1.1.0 at generation 2 with consent to the new digest, and the action answers proof.npm 1.1.0 running. plugins.consent with the old digest is then refused (source-changed).
Remove: the catalogue and npm list are empty, no plugin process is left, and the downloaded files are gone.
No package script ran: the only markers are the two activations. The package's postinstall, prepare and test markers are absent.

Remote pass (vp run dev --share, fresh isolated home, clients reached the server only through the tailnet HTTPS origin): every npm mutation from a remote standard pairing, and its remove, was refused with requiredScope=access:write, though it could list. A remote administrative session installed a package (needs-consent), approved and enabled it, ran its action, and removed it, leaving no files.

Checks at this head (25422fd6c3), re-run 2026-10-05 (vp test run, CI=true, all exit 0):

apps/server PluginNpm, PluginNpmRpc, npmTarball, PluginCatalog, PluginSupervisor, PluginSettings, PluginTools, PluginCatalogRpc and RpcAuthorization tests: 9 files, 99 tests pass. packages/contracts pluginNpm, pluginCatalog and plugin tests: 3 files, 17 tests pass.
PluginNpm.test.ts runs real plugin child processes from the installed files: install runs nothing until the digest is approved; tampered (integrity mismatch), unsafe, script-bearing and unbundled packages are refused and leave nothing behind; staged update keeps the old version running, applies with new consent, and the old digest is refused; rollback when the update fails after the swap; other management waits behind an apply; an update interrupted by a restart is finished or rolled back; file moves wait for a plugin whose disable was cut short; a home another installation now owns is kept; the reply, list, consent and running version agree whichever cleanup after the commit fails. A fault-injecting file system and deferreds order the steps; no sleeps.
npmTarball.test.ts: links, special files, paths with a colon and paths that leave the package are refused; corrupt or truncated archives; file, size, entry, path-length and header limits; macOS extended attributes.
PluginNpmRpc.test.ts serves the five RPCs through the real scope middleware: a standard pairing lists but every mutation is refused with requiredScope: access:write and no handler runs; an administrative session reaches every handler; a session without orchestration:read cannot list.
Recorded during development, on the parent: the npm and tarball test files cannot load, the three RPC scope tests fail, and the contracts npm test cannot load. With plugins.npm.add registered at orchestration:read, the denial test fails.
vp run --filter typecheck for @t3tools/contracts and t3; vp lint --report-unused-disable-directives and vp fmt --check on the touched files (three warnings, all on unchanged lines of ws.ts, present on the parent); vp run knip:check; web build; vp run build:desktop; node scripts/release-smoke.ts. All pass.

Surfaces

Entry points: none in the UI. Administrators use the plugins.npm.* requests; install and update buttons arrive with the management UI PR.
Clients: web, desktop and mobile unchanged. An npm installation is an ordinary catalogue row to every client, including remove.
Providers: not applicable; Codex, Claude, Cursor, Grok, OpenCode, Antigravity and Pi are unaffected.
Contracts: new pluginNpm.ts (records and inputs), five RPCs, optional pluginNpm environment capability, new open-string PluginCatalogError reasons. Old server: no capability, so clients do not call. New server + old client: new methods only; records ignore unknown fields.
Reverse states: install ↔ plugins.remove (files deleted after the plugin stops); stage ↔ discard; apply rolls back on failure; a restart forgets a staged update.
Connection modes: the RPCs add no transport and behave the same locally, over remote/relay and through the tunnel. The scope check is per session, so a remote standard pairing can list and cannot install. Downloads always happen on the server.
Docs: new docs/user/plugin-npm.md: installing, what is checked, writing a package for T3 Code (bundle dependencies), the two-step update and its re-approval, removal. The management UI PR consolidates the plugin pages into one guide. No internals doc.

Not verified

An update interrupted by a restart, rollback after a failed swap, the size, entry and path limits, links and .. paths, missing integrity, unbundled dependencies, a name or version mismatch, and a changed plugin id are shown by tests, not in the live trace.
The live trace used a local registry, not the public npm registry. The remote pass used the tailnet (--share) with a scripted RPC client; no relay or T3 Connect tunnel run.
No client calls the RPCs in this PR.
No signature or provenance check; no registry authentication; no automatic update checks.
npm.json publication by rename is atomic on the tested platform; fsync/power-loss durability and Windows rename semantics were not verified.
Windows and Linux were not run; the colon refusal is checked by the parser test, not by an extraction on NTFS.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a large, security-sensitive plugin platform with new code execution, npm installation, filesystem updates, secrets, RPC authorization, MCP tools, persistent migrations, and user-facing workflows. It also changes default capability advertisement and adds diagnostic suppressions, while an unresolved High finding remains in the tarball-size handling.

4680-4693: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

pluginViews gets a new identity on every render, so the useMemo never reuses its result.

sidePanelPluginViews(...) runs on every render. If it filters or maps the array, it returns a new array each time. In that case pluginViewLaunchers is rebuilt on every render. The launchers are passed to both RightPanelTabs instances, so the memo has no effect. Put the selector call inside the memo, or memoize the raw views.
♻️ Proposed fix
-  const pluginViews = sidePanelPluginViews(
-    usePluginViews(activeThreadRef?.environmentId ?? null).views,
-  );
+  const rawPluginViews = usePluginViews(activeThreadRef?.environmentId ?? null).views;
+  const pluginViews = useMemo(() => sidePanelPluginViews(rawPluginViews), [rawPluginViews]);

32-39: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Keep the underlying error as cause and build reason without raw error text.

PluginManifestError has no cause field. Every mapError in loadPluginDirectory throws away the underlying error. Line 105 also copies the schema decoder's error.message into reason. The catalogue saves that text as the installation problem and shows it to clients. The repository's Effect service rules say: "The message is fixed or built from those attributes, never from cause, cause.message, or a stringified defect." They also say: "An error that wraps a failure keeps the immediate underlying error as cause." Add an optional cause field. Pass the error at each wrapping site, and limit the length of the decode detail.
♻️ Proposed change
 class PluginManifestError extends Schema.TaggedError<PluginManifestError>()("PluginManifestError", {
   directory: Schema.String,
   reason: Schema.String,
+  cause: Schema.optional(Schema.Defect()),
 }) {
-  const fail = (reason: string) => new PluginManifestError({ directory, reason });
+  const fail = (reason: string, cause?: unknown) =>
+    new PluginManifestError({ directory, reason, ...(cause === undefined ? {} : { cause }) });
   const manifest = yield* decodeManifest(raw).pipe(
-    Effect.mapError((error) => fail(`${PLUGIN_MANIFEST_FILE} is invalid: ${error.message}`)),
+    Effect.mapError((error) =>
+      fail(`${PLUGIN_MANIFEST_FILE} is invalid: ${error.message.slice(0, 500)}`, error),
+    ),
   );

Move handler instructions out of the user guide.

This handler registration recipe explains how to implement a plugin, rather than how to use an action. Move the authoring recipe to developer documentation. Keep this page focused on enabling, finding, and running actions. As per coding guidelines, “Keep user docs in the shipped product's voice, without implementation details or contributor tooling.”

- Around line 3996-4006: In the composer slash-menu handler for plugin-action
items, check that the environment has orchestration:operate before applying the
prompt replacement or calling runPluginAction; reuse the same scope-checking
mechanism as the thread action menu and leave the composer unchanged when the
scope is missing.

- Line 83: Update the worktree-path fallbacks in TerminalSidePanel so they use
threadWorktreePath only when the corresponding terminal summary is absent;
preserve a summary’s null worktreePath, keeping it consistent with that
summary’s cwd and runtime environment.

Review comments at @docs/user/plugin-actions.md:
- Line 5: Update the plugin action description to clarify that, in a remote
environment, the plugin runs under the server process’s OS account rather than
the client’s OS user. Replace “as your OS user” with wording that identifies the
server account, while preserving the surrounding explanation that the action
does not write a prompt or start an agent turn.

Pre-merge checks failed. Please resolve the failing checks before merging.

A message bound below the IPC stream's own 64 KiB buffer could fill without any write reporting backpressure, so Node never emitted drain and the plugin's host calls and answers stayed blocked after it read again. Room is now also there whenever the stream is not waiting to drain. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Enabled plugins can declare actions in their manifest (capability `actions`). The server lists them from the consented manifest without starting the plugin and runs one on request through the plugin's `action:<name>` handler. Web, desktop and mobile offer them in the command palette, the composer slash menu and the thread menus; a server without `pluginActions` is never asked. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Since the Effect 4.0.1 rewrite of ForwardCompatibleArray, a forward-compatible array nested in another one drops the whole outer element when it drops an inner value. An action offered in a placement this client does not know therefore vanished instead of losing just that placement. Placements now filter unknown names directly. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Manifest action names are lowercase, but the offered action list accepts any name, so a newer server could send one with capitals that the lowercased query never matched. Web and mobile now lowercase the name before matching. The guide also notes that mobile offers the slash menu anywhere in the message. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…n them Running a plugin action needs orchestration:operate. The command palette and composer slash menu on web and mobile offered actions to read-only connections, and the slash menu removed the typed command before the server refused it. Both entry points now list plugin actions only when the connection can operate the environment, and a stale slash pick is refused before the draft changes. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The hook now reads plugin actions for the thread menu, and that module needs React context, which this test's minimal React mock does not provide. These tests cover the built-in menu items, so the plugin actions module is stubbed to return none. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The slash menu and palette offer plugin actions from the cached orchestration:operate grant, which can be stale after a reconnect. Picking a slash action now reads the live grant first: without it the draft stays untouched and nothing runs; with it the typed command is removed at pick time, as before, and the action runs. runPluginAction reads the live grant too, so a palette entry picked after the grant changed is refused, and it reports whether the plugin ran the action. Nothing writes the draft after the action settles. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…an open thread The mobile command palette loaded plugin actions only from the open thread's environment, so on a page without a thread it offered none, not even actions that target the environment. Take the open thread's environment, else the first connected one, and pass thread and project only when they exist, as the web palette does. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

A plugin with the `views` capability declares side-panel views (one script, optional stylesheet). The server serves each view's consented bytes per installation generation over three scoped RPCs and revokes them with the generation. Web and desktop list the current session's views in the right panel launcher and mount each in a sandboxed srcdoc frame bridged by one MessagePort; desktop also vetoes view-frame navigations in the main process. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The view bridge refilled its message bucket from the wall clock, so a clock that stepped back drained it and could close a healthy view for violations. Elapsed time is now never negative. The desktop window also logged the start of a refused plugin view URL, which can carry the view's data in its path or query; it now logs only the protocol and host. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

A view calls its plugin through handlers registered on context.proposed, which only exists with "proposedApi": true. A manifest that asked for views without it could be added and enabled, and then every call from its views failed. The loader now refuses it, as it does for the other proposed capabilities. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

When an environment had plugin views placed outside the side panel, the filtered list was rebuilt on every chat render, so the launchers and both right-panel tab strips got a new array each time. The filtered list is now memoized on the session's views. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…roup Typing every WebSocket handler against the instrumented group runs past the type checker's instantiation limit once the plugin view RPCs join main's WebSocket methods, and the checker then silently widens the server layer's requirements to `any`. RpcServer finds a handler by its tag alone, so the handlers are typed against the plain group while the server still runs the instrumented one. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A view asset such as `..board.js` sits inside the plugin directory, but the containment check treated any `..` prefix as leaving it, so the whole installation's views failed to load. Only a whole `..` segment now counts, matching the entry check in the manifest loader. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A view's files were read before the directory was digested, so a file changed for the read and restored before the digest served bytes that were never approved. Each read file's hash must now match the hash the digest pass took of it, and a file that several views share must read the same bytes every time. A view file that fails to read also runs the digest, so an approved plugin whose view was edited into an invalid file is disabled instead of keeping its stale approval. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…ed updates Adds `plugins.npm.list/add/stageUpdate/applyUpdate/discardUpdate`, gated on the `pluginNpm` environment capability. Install and update download one exact version, require the registry's sha512 integrity to match, check the whole archive in memory before writing it, refuse install scripts and unbundled dependencies, and hand the unpacked directory to the catalogue, which still requires consent to its digest before anything runs. Applying an update consents to the staged digest and swaps the files in one catalogue step; interrupted swaps are finished or rolled back at startup. Listing needs orchestration:read; installing and updating need access:write. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The integrity check compares the tarball with the sha512 the same registry publishes. Over plain http a network attacker can replace both, so the check authenticated nothing. Registries must now use https, except a loopback registry for local testing. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…https rule Only the registry typed into add was checked. Metadata requests followed redirects anywhere, so one plain http hop let a network attacker supply both the integrity and the tarball, and an update of an installation saved from a plain http registry skipped the check entirely. Metadata requests now follow each redirect only to https or a loopback registry, and every metadata lookup refuses a saved registry that is not one. Tarball downloads still follow redirects: their integrity comes from that metadata. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Three header cases were misread. A GNU header's `ustar ` magic passed the POSIX check, so its access time became a path prefix and files landed under the wrong names. A directory entry's size is space to reserve, not data, so a nonzero one shifted every later header. A pax global header that sets `path` or `size` was skipped, so later entries kept names and sizes their writer did not mean. Only the full POSIX magic and version now read a prefix, directories carry no data, and a global path or size is refused. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A staged update's summary was built by its own copy of the manifest summarizer, which left out tools, settings, and actions, so an administrator reviewing an update could not see changes to them before applying it. The npm installer now uses the catalogue's summarizer, so the review shows exactly what the catalogue will list once the update is applied. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The inflate cap allowed 1.5 KiB of header and padding per file, but directories and extended headers are entries of their own, so an archive inside the file, byte, and entry limits could still be refused as too large. The cap now budgets every entry and one tar record of end padding. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The pax reader dropped each record's last declared byte as its newline without checking it, so a malformed record such as `20 path=package/fooX` renamed the next file instead of being refused. A record whose last byte is not a newline now makes the archive unsafe. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

PluginNpm now reaches the plugin catalogue through its module namespace and builds each PluginCatalogError where the failure happens instead of through a forwarding helper. A failed file step keeps the file system error as the storage error's cause, and every Node builtin import exemption in the npm install modules says why it is needed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A pax size waiting for the next file was applied to a GNU long-name record in between, so the reader misread the name and refused a valid archive. Extended headers now always use their declared size. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A pax path may carry a NUL, which passed the path checks and then failed the staging write after earlier files were already written. Such an archive is now refused before anything is staged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…nabled again When enabling the plugin again failed after the consent to the new files was saved, applying the update reported a failure although the new version was installed, and a retry found no update to apply. It now returns the applied version and the installation as it is. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Applying an update whose files match the installed ones could lose the package: after a restart between the two moves, recovery read the existing consent as a finished swap and deleted the only copy. Such an update is now discarded before anything moves. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
