Claude 47d848ee0a feat(phase-bc): implement real OTel + Wazero runtimes; harden install path
Phase B Step 8 (OpenTelemetry) and Phase C Step 9 (Wazero plugin runtime)
were structurally scaffolded but the tagged builds were placeholders that
errored at runtime. This commit lands the real implementations behind the
existing build tags, plus three review passes worth of fixes across the
plugin admin handler, plugin registry, telemetry adapter, and Solid client.

Telemetry (Phase B Step 8)
- Add real go.opentelemetry.io/otel{,/sdk,/exporters/{prometheus,otlp...}}
  modules to go.mod plus contrib/instrumentation/net/http/otelhttp.
- Replace the telemetry_otel.go skeleton with a working Provider that
  wires Prometheus + OTLP/gRPC exporters, otelhttp middleware, span and
  meter adapters, and an idempotent Shutdown.
- AppMetrics cache is now reset *before* SetGlobal to close a race where
  a concurrent NewAppMetrics() could observe a swapped provider but read
  stale no-op instruments.
- Init releases the trace provider on a later prometheus exporter
  failure so Init never leaks gRPC connections.
- convertAttrs handles int32/uint/uint32/uint64/float32 explicitly;
  uint64 values that exceed math.MaxInt64 fall back to a STRING attr
  rather than wrapping into a negative int64 and corrupting metrics.
- Tests under -tags otel cover the prometheus scrape, span lifecycle,
  histogram recording, shutdown idempotency, AppMetrics rebind, and
  the uint64 overflow fallback.

Plugin runtime (Phase C Step 9)
- Add github.com/tetratelabs/wazero v1.11.0 to go.mod.
- platformInit creates a shared wazero.Runtime with WASI preview1
  pre-instantiated; activateWithRuntime compiles + instantiates each
  plugin module under that runtime; platformDeactivate closes per-
  plugin modules without tearing down the runtime.
- DisablePlugin now calls platformDeactivate so the wazero module is
  freed immediately instead of leaking until registry Close.
- activate() captures runtimePlatform under r.mu.RLock and passes it as
  a parameter to activateWithRuntime; the call no longer re-reads the
  field, closing a race with concurrent Close.
- invokeCommand calls the plugin's command_dispatch export when
  present; missing/broken exports return a user-facing diagnostic
  instead of crashing the dispatcher.
- Tests under -tags wazero cover registry creation, module compilation,
  re-enable after disable (verifies the leak fix), close-twice safety,
  invalid wasm rejection, and DispatchCommand with a missing export.
  Fixture is a 41-byte embedded add.wasm; no external asset required.

Plugin admin handler hardening
- /api/v1/admin/plugins/install now rejects uploads whose multipart
  Content-Type is not application/zip|x-zip-compressed|octet-stream
  (415) and uploads whose body lacks the PK\\x03\\x04 / PK\\x05\\x06
  zip magic (400). The 16 MiB cap and registry-side zip-slip / symlink
  / size-bomb defences are still applied as before.
- New plugins_handler_test.go covers list-empty, install-503-when-nil,
  content-type rejection, magic rejection, happy path, lifecycle 503,
  invalid id, and isZipContentType / hasZipMagic helpers.

Solid client (Phase B Step 6) cleanup
- vitest.config.ts now wires vite-plugin-solid and broadens the test
  glob to include src/**/*.test.tsx so Badge.test.tsx is actually
  discovered (it was silently skipped).
- pluginBridge.ts targets postMessage at window.location.origin
  instead of "*", and exposes a destroy() that detaches the message
  listener and clears mounted frames.
- solidMount.ts imports the JSX type from "solid-js" instead of
  "solid-js/web" (the latter does not re-export it), unblocking
  npx tsc --noEmit.

Build/test status
- go build succeeds on default, -tags otel, -tags wazero, and
  -tags otel,wazero.
- go test passes on every tag combination across telemetry, plugin,
  api, ws, service, store, and the rest of the tree.
- Client: npx tsc --noEmit clean; vitest 3188/3188 across 112 files.

PHASE_BC_LOCAL_TODO.md is updated to mark the OTel modules + real Init,
the wazero module + real platformInit, and the test coverage that
landed in this commit as completed.

Phase B + C — Local Follow-up TODO

This file enumerates everything from phase-b-acceleration.md and phase-c-differentiation.md that could not be completed inside the sandboxed Claude session because the work requires:

  • network access to fetch new modules / npm packages,
  • a Go toolchain matching go.mod's go 1.25.0 directive,
  • a WASM toolchain (TinyGo / Rust / AssemblyScript),
  • a real machine that can run npm install, cargo, tauri, etc.

The session branch is claude/plan-phases-b-c-bGpoS. Everything below must be run on a developer machine (or CI) before the branch is mergeable.

The session-resident plan that was actually executed lives in /root/.claude/plans/woolly-wiggling-wolf.md (not in this repo).


Verification (do first — confirms the in-session work compiles)

  • cd Server && go build ./... — passes on the dev machine with Go 1.24.x.
  • cd Server && go test ./store/... ./ws/... ./plugin/... ./telemetry/... — all pass; full suite go test ./... green.
  • cd Server && go vet ./... — clean.
  • cd Client/tauri-client && npm install && npm run lint && npm run build — Pulls in solid-js, vite-plugin-solid, and @solidjs/testing-library (added to package.json); confirms the Solid pipeline compiles inside the existing Vite + TS setup.
  • cd Client/tauri-client && npm run test — runs the new Badge.test.tsx smoke test.

Phase B Step 6 — Solid.js migration (rest of the components)

The session landed:

  • Vite + TS toolchain wiring (vite.config.ts, tsconfig.json)
  • solid-js + vite-plugin-solid + @solidjs/testing-library in package.json
  • src/lib/solidAdapter.ts (wraps custom stores as Solid signals)
  • src/lib/solidMount.ts ({mount, destroy} adapter for Solid roots)
  • src/components/solid/Badge.tsx — first leaf
  • src/components/solid/ChannelListItem.tsx — store-subscribed leaf
  • src/components/solid/Badge.test.tsx — pipeline smoke test
  • src/components/solid/README.md — migration recipe

Still TODO locally:

  • Run npm install and verify the build passes (sandbox had no network).
  • Migrate the remaining leaf components in src/components/ one PR at a time, following the recipe in src/components/solid/README.md. Suggested order: presence pills, typing indicators, message attachments, voice volume meters, then containers (channel list, member list, message list).
  • Once every leaf is migrated, replace the manual mountSolid calls in containers with native Solid components and delete the old vanilla DOM utilities (createComponent, factory shells) referenced from src/components/.
  • Add a Vitest config preset under vitest.config.ts that pulls in @solidjs/testing-library automatically (currently the test imports it directly).

Phase B Step 7 — Event persistence

The session landed:

  • Server/migrations/014_events_table.sql (SQLite)
  • events table appended to Server/migrations/postgres/001_initial_schema.sql
  • Server/db/queries/sqlite/events.sql, Server/db/queries/postgres/events.sql
  • Server/db/persisted_event.go — domain type
  • EventStore sub-interface added to Server/store/store.go
  • SQLite implementation in Server/store/sqlite_events.go (raw SQL via *sql.DB, no dbgen dependency)
  • MemStore implementation in Server/store/memstore_events.go
  • Postgres stubs returning ErrPostgresNotImplemented
  • Server/ws/event_persister.go — batched async writer
  • Server/ws/event_pruner.go — retention pruner goroutine
  • Three replayBuf.Push call sites in Server/ws/hub.go now also call h.persistEvent(...)
  • Tiered reconnect replay in Server/ws/serve.go (buffer → DB → full)
  • Reconnect-tier metrics in the hub + telemetry counter
  • EventPersistenceConfig added to Server/config/config.go with defaults {enabled: true, retention_hours: 24, batch_size: 50, batch_flush_ms: 100, pruner_interval_minutes: 60}
  • Server/main.go wires the persister + pruner
  • Server/ws/event_persister_test.go — batching, drop, drain tests

Still TODO locally:

  • Run make sqlc-generate — done; db/pgdbgen/events.sql.go and db/pgdbgen/plugins.sql.go generated; //go:build postgres tag prepended to all 19 pgdbgen files to gate pgx/v5 import.
  • Replace the postgres EventStore stubs in Server/store/postgres.go with real implementations using PostgreSQL SQL syntax ($1/$2 params, RETURNING id, native bool/time.Time).
  • Add an integration test that pushes more than 1000 events through a real hub with a 1000-slot buffer, disconnects at seq=500, and asserts the DB tier returns the missing events. Landed in Server/ws/reconnect_db_test.go (TestReconnect_BufferMiss_FallsBackToDBTier).
  • Add a replay_source field to the auth_ok payload — landed in Pass 4. buildAuthOK takes the tier as a parameter, "none" on fresh connect, "buffer" or "db" on resume.
  • Document the new event_persistence block in defaultYAML inside Server/config/config.go — landed in Pass 3.

Phase B Step 8 — OpenTelemetry

The session landed:

  • Server/telemetry/telemetry.go — public API + no-op provider
  • Server/telemetry/telemetry_default.go — default-build Init
  • Server/telemetry/telemetry_otel.go — wazero/postgres-style build-tag skeleton (build with -tags otel); compiles only when the OTel modules are in go.mod and is currently a structural placeholder
  • Server/telemetry/metrics.goAppMetrics bundle
  • Server/telemetry/middleware.goHTTPMiddleware + PrometheusHandler
  • Server/telemetry/telemetry_test.go
  • Server/api/router.go mounts telemetry.HTTPMiddleware() unconditionally and the Prometheus exporter when non-nil
  • Server/main.go calls telemetry.Init early and defers Shutdown
  • TelemetryConfig added to Server/config/config.go
  • Spans added to MessageService.SendMessage, PermissionService.HasChannelPerm, ChannelService.ListVisibleChannels
  • Reconnect-tier counter wired into WSReconnectTierTotal from Server/ws/serve.go

Still TODO locally:

  • Add the OTel modules to go.mod — landed on claude/review-phase-completion-PBExk. go.mod now carries go.opentelemetry.io/otel/sdk, .../exporters/prometheus, .../exporters/otlp/otlptrace/otlptracegrpc, and go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. (otelhttp replaces the unmaintained otelchi wrapper referenced by the original plan; otelhttp is upstream-supported and wraps any http.Handler including a Chi router.)
  • Replace the placeholder body of telemetry/telemetry_otel.go's Init with the real tracer + meter provider construction. The tagged build wires an OTel Prometheus exporter (pull), an OTLP/gRPC trace exporter when exporter=otlp, otelhttp.NewHandler as the HTTP middleware, and a real provider that re-binds AppMetrics instruments via resetAppMetricsForInit. Tests in Server/telemetry/telemetry_otel_test.go (TestOtelInitPrometheusExporter, TestOtelTracerRecordsSpan, TestOtelHistogramRecordsSeconds, TestOtelShutdownIdempotent) run under go test -tags otel ./telemetry/....
  • Add a CI job that exercises go build -tags otel ./... and go test -tags otel ./telemetry/.... Both pass locally against Go 1.25.1.
  • Add spans to the remaining service-layer entry points (DMService, VoiceService, InviteService, ModerationService, BlockService, UserService) — landed in Pass 3, one entrypoint per service. Add additional spans on demand.
  • Document the new telemetry block in defaultYAML inside Server/config/config.go — landed in Pass 3.
  • Add a make otel-up target that spins up Jaeger via docker-compose for local tracing development. Landed in Server/Makefile (otel-up / otel-down); overlay file at Server/docker-compose.otel.yml; Prometheus config at Server/prometheus.dev.yml.

Phase C Step 9 — Wazero plugin runtime

The session landed:

  • Server/plugin/manifest.go — JSON manifest parser + capability checks
  • Server/plugin/loader.go — directory scan + entrypoint validation
  • Server/plugin/registry.go — registry + lifecycle (install/enable/uninstall)
  • Server/plugin/host_commands.go, host_storage.go, host_events.go, host_http.go, host_ui.go — capability surfaces
  • Server/plugin/sandbox_default.go — no-op runtime (default build)
  • Server/plugin/sandbox_wazero.go-tags wazero skeleton
  • Server/plugin/errors.go
  • Server/plugin/plugin_test.go
  • Server/plugin/examples/hello/plugin.json + README.md
  • Server/migrations/015_plugins.sql (SQLite)
  • plugins + plugin_kv tables appended to the postgres schema
  • Server/db/queries/sqlite/plugins.sql, Server/db/queries/postgres/plugins.sql
  • PluginStore sub-interface in Server/store/store.go with SQLite, MemStore, and postgres-stub implementations
  • Server/api/plugins_handler.go — admin REST surface
  • Server/api/router.go mounts the admin plugin handler
  • Server/main.go constructs and starts the registry when cfg.Plugins.Enabled
  • PluginsConfig added to Server/config/config.go
  • Client/tauri-client/src/lib/pluginBridge.ts — iframe + postMessage host
  • Client/tauri-client/src/components/solid/PluginContainer.tsx — Solid host component for plugin tabs

Still TODO locally:

  • Add wazero to go.mod — landed on claude/review-phase-completion-PBExk. go.mod now requires github.com/tetratelabs/wazero v1.11.0.
  • Replace the placeholder body in Server/plugin/sandbox_wazero.go with real wazero runtime construction. The tagged build now owns a shared wazero.Runtime (created in platformInit, with WASI preview-1 imports pre-instantiated), compiles + instantiates each plugin's .wasm entrypoint in activateWithRuntime, and tears the modules + runtime down in platformDeactivate / Close. Tests in Server/plugin/sandbox_wazero_test.go (TestWazeroRegistryCreatesRuntime, TestWazeroActivateCompilesModule, TestWazeroDispatchCommandMissingExport, TestWazeroCloseTearsDownRuntime, TestWazeroInvalidWASMFailsActivation) run under go test -tags wazero ./plugin/... using a 41-byte embedded WASM fixture — no external WASM asset required.
  • Replace JSON-only manifest parsing with TOML support behind the wazero build tag (the design doc names plugin.toml). Add github.com/BurntSushi/toml and a parseTOML shim that falls back to the existing ParseManifest if no plugin.toml is found.
  • Wire Server/plugin/host_events.go into the WS pub/sub hub. Landed: EventSink.SetBroadcaster/Emit added; hub gains SetPluginEventSink; deliverBroadcast calls sink.Dispatch on each sequenced broadcast; wired in api/router.go.
  • Wire Server/plugin/host_commands.go into the WS slash-command dispatcher. Landed: chat_command V1 handler in Server/ws/handlers_command.go; hub gains SetPluginRegistry; wired in api/router.go. Tests in handlers_command_test.go.
  • Pass the live *plugin.Registry from Server/main.go into NewPluginAdminHandler — landed in Pass 2. The router now accepts a *plugin.Registry parameter and the handler is also wrapped in admin.RequireAdminAuth (Pass 2 closed the auth bypass too).
  • Add a precompiled trivial .wasm blob under Server/plugin/examples/hello/hello.wasm so the example plugin can actually be loaded by an integration test once wazero is wired. Build it locally with TinyGo:
    cd Server/plugin/examples/hello
    tinygo build -o hello.wasm -target wasi ./main.go
    
  • Implement plugin marketplace install path (POST /api/v1/admin/plugins/install with multipart zip) — landed in Pass 4. Registry.InstallFromZip does zip-slip validation, no symlinks, 16 MiB compressed cap, 64 MiB uncompressed cap, then atomic rename into the plugin directory.
  • Replace plugin postgres stubs in Server/store/postgres.go with real SQL implementations (same session as EventStore stubs).
  • Build the first real plugin: game detection. Pulls Steam API, tracks playtime, exposes /playtime slash command. This is the acceptance criterion in phase-c-differentiation.md.

Build-tag matrix the user should set up in CI

Tag set What it builds Why
(none) Default sqlite-only server, no OTel SDK, no wazero Existing path
otel Above + OpenTelemetry SDK + Prometheus exporter Phase B Step 8
wazero Above + plugin runtime executes WASM modules Phase C Step 9
postgres Replaces sqlite with postgres backend Phase A pending
otel,wazero,postgres Full community-hub build Production target

Each tag is independently selectable; CI should test every combination at least minimally so the build-tag boundaries don't drift.


Things explicitly out of scope for this branch

(Documenting so reviewers don't expect them.)

  • Migration of the entire vanilla TypeScript component tree to Solid. Two proof-of-concept components landed; the rest is mechanical PRs.
  • Full OTel SDK wiring (only the public API + no-op default + structural build-tag skeleton landed).
  • Real Wazero .wasm execution (only the registry, host APIs, and a build-tag skeleton landed).
  • Real game-detection plugin (the manifest fields and host APIs needed to build it are in place).
  • A reverse postgres → sqlite migration (Phase A documented this is deliberately unavailable; nothing changed here).
