Phase B Step 6 — Solid.js incremental migration
- vite-plugin-solid + solid-js + @solidjs/testing-library in package.json
- vite.config.ts compiles src/components/solid/** as Solid TSX
- tsconfig.json gains jsx: preserve / jsxImportSource: solid-js
- lib/solidAdapter.ts wraps existing custom Stores as Solid signals
- lib/solidMount.ts adapts Solid render to {mount,destroy} contract
- components/solid/Badge.tsx (proof-of-concept leaf)
- components/solid/ChannelListItem.tsx (store-subscribed leaf)
- components/solid/Badge.test.tsx pipeline smoke test
- components/solid/README.md documents the migration recipe
Phase B Step 7 — Event persistence layer
- SQLite + Postgres migrations for the events table
- sqlc query files for both engines
- EventStore interface + SQLite raw-SQL impl + MemStore impl + pg stubs
- ws.EventPersister: async batched writer (queue / flush / drain / drop)
- ws.StartEventPruner: background retention pruner
- hub persists every replay-buffer push and exposes reconnect-tier counters
- serve.handleReconnect: tiered replay (buffer -> DB -> full re-sync)
- EventPersistenceConfig + main.go wiring
- event_persister_test.go covers batching / drops / drain
Phase B Step 8 — OpenTelemetry skeleton
- Server/telemetry package with public Provider/Tracer/Meter/Counter API
- telemetry_default.go (no-op build) + telemetry_otel.go (build tag otel)
- telemetry/metrics.go declares the AppMetrics bundle
- HTTPMiddleware mounted in Chi router (pass-through in default build)
- PrometheusHandler optionally mounted at /metrics
- Spans on MessageService.SendMessage, PermissionService.HasChannelPerm,
ChannelService.ListVisibleChannels
- Reconnect-tier counter wired into the global meter
- TelemetryConfig defaults
Phase C Step 9 — Wazero plugin runtime skeleton
- Server/plugin package: manifest parser, loader, registry, host APIs
(commands, storage, events, http, ui), errors
- sandbox_default.go (no-op) + sandbox_wazero.go (build tag wazero)
- SQLite + Postgres migrations for plugins + plugin_kv tables
- PluginStore interface + impls + pg stubs
- plugin/examples/hello manifest + README
- plugin_test.go covers manifest, loader, capability gating
- api/plugins_handler.go admin REST surface, mounted under admin group
- PluginsConfig + main.go wiring (disabled by default)
- Client: lib/pluginBridge.ts iframe + postMessage host
- Client: components/solid/PluginContainer.tsx Solid host component
Verification
- Default build (no -tags) is intended to compile cleanly with no new
third-party dependencies. The sandbox lacked Go 1.25.0 so go build
could not run; PHASE_BC_LOCAL_TODO.md enumerates the local follow-up
work (npm install, go mod tidy, sqlc-generate, real otel/wazero
wiring, remaining service spans, full Solid migration).
