* feat: add plugin system with grpc runtime and native ui plugins - go plugin backends ship as release tarballs (per-platform binaries, checksums) that kandev installs from url/upload or filesystem sideload+sync, then spawns and supervises via hashicorp/go-plugin (unix socket / loopback tcp+automtls) - strict typed grpc contract (kandev.plugin.v1): DeliverEvent/InvokeTool/HandleWebhook plus a capability-gated host service (state, secrets, emit); author sdk in pkg/pluginsdk; packaging cli in cmd/plugin-pack - native frontend bundles: window.registerKandevPlugin + registry/host loader with dynamic routes, nav items, slots and ws handlers; plugins settings page with install dialog, sync button and enable/disable/uninstall - gated behind the plugins feature flag (prod off, dev/e2e on); covered by unit and integration tests plus playwright e2e against a real packaged fixture plugin Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(plugins): hydrate base app context on plugin routes Plugin-owned SPA routes classify as RouteUnknown, so the boot payload shipped only feature flags — no workspaces, workflows, or kanban context. Native plugin UI (e.g. host.ui.TaskCreateDialog) then had an empty store. Hydrate the same base context as the Home route for unknown SPA routes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(plugins): expose TaskCreateDialog on host.ui Lets a native plugin open kandev's real create-task modal (prefilled via initialValues) instead of POSTing directly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(plugins): harden filesystem/URL sinks against CodeQL findings Add sink-level guards on the plugin trust boundary: securejoin containment on archive extraction (zip-slip), plugin-id validation before every fs_store path, http/https scheme validation on install-from-URL, and non-interpolated ws-handler error logging. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(plugins): address review findings (races, resource caps, lifecycle) - serialize per-plugin startup to close a TOCTOU double-spawn race, and let a plugin restart after exhausting attempts - bound plugin startup with an explicit 30s timeout - reject backslash paths and cap decompressed bytes by actual size in pkgtar; only mark a package Signed when a verifier actually ran and passed - delete plugin_state on uninstall; validate webhook keys against the manifest and cap webhook body size; restart an active plugin when a new version installs Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(plugins): sanitize plugin-id path sinks for CodeQL Pin the plugin id to a single path segment with filepath.Base at recordPath/ configPath and pkgtar.Remove — a barrier the taint analysis recognizes. Behaviour-identical for valid ids (already validated by safePluginID); clears the go/path-injection alerts. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(plugins): inline plugin-id validation at path sinks for CodeQL filepath.Base does not strip '..', so it is not a path-injection barrier. Call the recognized safePluginID / id-pattern guard inline in Delete/GetConfig/ SetConfig and pkgtar.Remove — the same barrier that already cleared the Get sink. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(plugins): address code-review findings (backend) - add capability-gating tests for the Host RPC service (was untested) - close a stop-during-start orphan race so Disable/Uninstall can't leave a supervised subprocess behind - on failed upgrade, remove only the new version dir (not all versions + data); restart the prior version - validate manifest version and reject ids ending in .config (record-file alias) - make Deliverer.Refresh non-blocking and cancel in-flight delivery on worker stop - clamp out-of-range webhook status, skip-and-warn corrupt records in List, write records atomically, semver-aware sideload version pick Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(plugins): address code-review findings (frontend) - wrap plugin routes + settings routes in a shared PluginErrorBoundary so a throwing plugin page shows a fallback instead of white-screening the SPA - fix disable/re-enable in one session: keep the cached registration and re-run initialize instead of relying on a cached ES-module re-import - prefix root-relative bundle/style URLs with apiBaseUrl (split-origin/Tauri) - surface partial-install warnings via toast.warning instead of a bare success - dedupe/remove injected style links on unload; gate PluginNavItems on the flag Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(plugins): serialize per-plugin lifecycle + guard config writes - add a per-plugin keyed lock in Service so concurrent Enable/Disable/Install/ Uninstall/UpdateConfig for one id are serialized (no status-machine race) - take s.mu in SetConfig/GetConfig and write config atomically - bound each plugin initialize() with a timeout so one hung bundle can't stall the rest of the boot load Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(plugins): split service_test.go to satisfy file-length lint Move the install/URL test group into service_install_test.go; no logic change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * ci: build and ship the e2e fixture plugin package to E2E shards The plugin E2E specs' global-setup requires apps/backend/.build/kandev-plugin-e2e-1.0.0.tar.gz. Build it in the E2E build job, upload it as an artifact, and download it in both the regular and container shard jobs.

# Fixture plugin binary
|
|
|
|
## Title
|
|
Standalone Go HTTP server implementing the plugin contract, for Go integration
|
|
tests and Playwright e2e.
|
|
|
|
## Inputs
|
|
- Spec `docs/specs/plugins/spec.md` → event delivery headers/HMAC, tool
|
|
invocation, webhook proxy, UI page contract.
|
|
- Must be self-contained: only stdlib + `crypto/hmac`,`crypto/sha256`. NO imports
|
|
from `internal/plugins` (proves the contract is decoupled).
|
|
|
|
## Acceptance
|
|
1. `apps/backend/cmd/plugin-fixture/main.go` starts an HTTP server on a port from
|
|
`-addr`/`PLUGIN_FIXTURE_ADDR` (default `127.0.0.1:0` → print chosen addr on
|
|
stdout as `LISTENING <addr>` so tests can capture it).
|
|
2. Endpoints:
|
|
- `GET /health` → 200 `{"status":"ok"}`.
|
|
- `POST /events` → verifies `X-Kandev-Signature: sha256=<hmac>` against
|
|
`HMAC-SHA256(secret, rawBody)` using secret from `-secret`/`PLUGIN_FIXTURE_SECRET`;
|
|
records delivery (event_type + event_id) in memory; returns 200. Bad sig → 401.
|
|
- `POST /tools/echo` → returns `{"output": <input>}`.
|
|
- `POST /webhooks/test-hook` → records the call; returns 200.
|
|
- `GET /ui/dashboard` → returns a small HTML page with `<h1 id="plugin-dashboard">Fixture Plugin</h1>`
|
|
and a `<script>` that reads theme via postMessage (enough for e2e to assert render).
|
|
- `GET /_debug/deliveries` → JSON list of recorded event_types (test-only introspection).
|
|
3. Graceful shutdown on SIGINT/SIGTERM.
|
|
|
|
## Files
|
|
- `apps/backend/cmd/plugin-fixture/main.go`
|
|
- `apps/backend/cmd/plugin-fixture/main_test.go` (spins the server, asserts health +
|
|
HMAC accept/reject + echo)
|
|
|
|
## Verification
|
|
- `go test ./cmd/plugin-fixture/...` from `apps/backend`
|
|
- `go build ./cmd/plugin-fixture` from `apps/backend`
|
|
- `make -C apps/backend lint`
|
|
|
|
## Output contract
|
|
Report: chosen flags/env, the `LISTENING <addr>` handshake, endpoints implemented,
|
|
how HMAC is verified. Stay within `apps/backend/cmd/plugin-fixture/`.
|
|
|
|
## Dependencies
|
|
None.
