Claude Fable 5	0875e2a087	Add the sandbox host runtime for plugin iframes (#73) ... Implements the security core of the plugin system: code-plugin surfaces run in opaque-origin iframes (sandbox="allow-scripts", never allow-same-origin) with a capability-filtered RPC bridge. - api: serve a per-plugin sandbox frame document at /plugins/:id/:version/frame with a CSP that pins every load to the plugin's own asset path (built from APP_BASE_URL, not the request Host, so a Host-rewriting proxy cannot break it) and forbids network access (connect-src 'none'). Plugin assets get Access-Control-Allow-Origin: * so the null-origin frame can load its own module bundle. - web: sandbox-host creates the frame, wires the SDK host bridge over a source-filtered postMessage transport, drives render under a 5 s deadline (hung/failed plugin -> placeholder, never a frozen page), and tears down on unmount. PluginFrame/PluginPreviewPage surface it; the built-in ui.resize handler clamps plugin-requested heights. - plugin-sdk: host bridge reports gate violations via onViolation and registers a gated handler for every v1 method, so an undeclared capability is rejected with capability_not_permitted (not unknown_method). - tests: SDK gate unit test; web sandbox unit tests (opaque origin, source filtering, timeout); and the e2e security pack with a permanent malicious fixture plugin proving no escape (DOM/cookies/storage/fetch/ undeclared capability all blocked) plus well-behaved and hung cases.

Claude Opus 4.8	621aa47244	Add plugin storage, install API, and directory watcher (#71) ... Backend for installing plugin ZIPs (ADR 0008, plugin-architecture.md §Lifecycle, security.md §Plugins). Consumes the #70 SDK for validation. - Schema: `plugins` (id, name, version, apiVersion, kind, mode, manifest jsonb, removedAt soft-delete) + `pond_plugins` (per-pond activation) + `PluginInstanceMode` enum; migration 20260710130000_plugins. - `PluginPackageService`: pure, stateless ZIP → validated package via fflate — structure check, manifest validation (SDK), apiVersion gate, kind/bundle/styles rules, CSS sanitation (no @import / external url() / expression()), zip-slip and unpacked-size guards. Each failure carries a stable PluginErrorCode; manifest issues travel as ApiError details. - `PluginStorageService`: on-disk layout `<PLUGINS_DIR>/<id>/<version>/`; atomic writeVersion (staging dir + rename, no 404 window mid-update), removeVersion/removePlugin, traversal-safe asset resolution, dropzone + quarantine dirs. - `PluginsService`: install/update (update only to a strictly higher version, preserving the admin's instance mode; files land before the metadata pointer flips) / uninstall (refused while required; soft-delete + files removed + pond activations dropped) / list / get. - `POST/GET/DELETE /admin/plugins` (SiteAdminGuard, multer memory upload), error→HTTP-status mapping. Public version-pinned static serving at `GET /plugins/:id/:version/*rest` with immutable cache + nosniff, only for the installed current version. - `PluginWatcherService`: watches `<PLUGINS_DIR>/_dropzone/`, runs the same validation, installs valid drops and quarantines invalid ones with the error logged; inert under NODE_ENV=test (tests drive processDropped). - SDK: `compareVersions`/`isHigherVersion`. shared: `PluginView`, `PluginInstanceMode`, `PLUGIN_ERROR_CODES`, `PLUGINS_DIR` env, plugin error i18n (de+en). Compose: `plugins` volume + `PLUGINS_DIR`. - Tests: package unit test (valid + each invalid class) and an e2e DB test (GUI install + immutable serving, non-admin 403, invalid-manifest details, dropzone install + quarantine, atomic higher-only update, required-guarded uninstall that removes files and tombstones metadata).

Claude Opus 4.8	ec6ca80c4d	Add plugin SDK: manifest schema, capabilities, and RPC protocol (#70) ... The SDK is the contract every other M7 story builds on (ADR 0008, plugin-architecture.md). New package `@dorfteich/plugin-sdk`, standalone (only depends on zod) so a plugin author needs nothing else. - Zod manifest schema (`validateManifest`/`parseManifest`) with actionable `{ path, message }` issues and cross-field rules (extension-point/kind match, unique ids, section_style declares no permissions). Fixtures: 3 valid + 14 invalid variants, asserted individually. - `checkApiVersion` compatibility helper against the host's supported range. - Capability names + method→capability map as the single source of truth for the permission gate. - Transport-agnostic postMessage RPC engine (`createRpcEndpoint`) with request/response ids, per-request timeouts, unknown-method and endpoint-disposed handling, plus a `windowTransport` adapter. - Host side (`createHostBridge`): routes plugin capability calls through the manifest permission gate; drives plugin lifecycle (render/edit/destroy). - Plugin side (`createPlugin`): answers lifecycle calls, exposes a typed `host` proxy. RPC roundtrip verified in a jsdom MessageChannel test (roundtrip, args, timeout, unknown method, undeclared capability, dispose). - README documents the protocol with a mermaid sequence diagram.
