The integration is **opt-in and host-app +driven** so that only the CoMapeo Mobile app pays the bundle cost, +sends events to a DSN, and sees its data in Sentry — other apps that +depend on this module continue to ship with no Sentry traffic and no +Sentry binaries. + +Companion docs: +- [`ARCHITECTURE.md`](./ARCHITECTURE.md) — process model, IPC, lifecycle. +- Reference implementation in CoMapeo Mobile: + [`comapeo-mobile/src/backend/src/app.js`](https://github.com/digidem/comapeo-mobile/blob/develop/src/backend/src/app.js). +- Upstream OpenTelemetry instrumentation in `@comapeo/core`: + [`comapeo-core PR #1051`](https://github.com/digidem/comapeo-core/pull/1051). + +--- + +## 1. Goals & non-goals + +### Goals + +1. **Capture errors** raised at every layer the module owns: + - Node backend: `uncaughtException`, `unhandledRejection`, boot + phase failures (`listen-control`, `init`, `construct`, + `runtime`), per-RPC throws. + - RN/JS layer: `state` ERROR transitions, `messageerror` protocol + parse failures, RPC client rejections. + - Native: rootkey load failures, watchdog timeouts, IPC + connection errors, hard process crashes (Android FGS, + iOS in-process). +2. **Trace RPC calls** end-to-end across the React Native ↔ Node + boundary, mirroring the `onRequestHook` pattern used in + `comapeo-mobile/src/backend/src/app.js`. Each RPC call appears + as a transaction whose parent span is the JS-side caller. +3. **Forward OpenTelemetry spans** emitted by `@comapeo/core` (once + PR #1051 lands) to Sentry without bundle-time coupling to a + specific exporter. +4. **App-specific gating**: zero Sentry traffic, zero Sentry SDK + activation, and ideally zero meaningful bundle delta for any + consumer that doesn't opt in. + +### Non-goals + +- We are not adding a generic telemetry abstraction. The module + speaks Sentry-shaped APIs (DSN, `Sentry.captureException`, + OpenTelemetry-compatible spans). Other backends are out of scope. +- We are not capturing user-PII or message contents. Spans get + method names and structural metadata, not arguments. +- We are not auto-installing Sentry SDKs on the host app's behalf. + The host app declares the dependency; the module just wires it in. + +--- + +## 2. Why "app-specific" matters here + +`@comapeo/core-react-native` is a library. It has at least two +different consumers expected over time (the CoMapeo Mobile app, and +the in-tree `apps/example` integration harness — and potentially +third-party apps building on the module). We cannot: + +- **Bundle a hard dependency on `@sentry/node` into the published + Node backend.** That bundle is staged into + `android/src/{debug,main}/assets/nodejs-project/` and + `ios/nodejs-project/` at `npm run backend:build` time + (see `backend/rollup.config.ts` and + `scripts/build-backend.ts`). Whatever ends up in the rollup is on + every consumer's device, regardless of whether they want Sentry. +- **Hard-import `@sentry/react-native` from `src/`.** Doing so + would force every consumer to install it, and any consumer that + does not call `Sentry.init()` would still get a runtime warning + from the module attempting to use an uninitialized client. +- **Ship a DSN.** The DSN is per-app secret (well, per-app config). + It belongs in the host app's environment, not in the published + module's source. + +The integration must therefore be: + +1. **Inert by default.** Module installed but not configured → no + Sentry calls, no SDK init, no trace metadata on RPC frames. +2. **Activated by the host app.** A single configuration entry + point, called from the host app's startup code, switches + instrumentation on with a DSN, environment, release, sample + rates, etc. +3. **Reachable from all three layers.** The same call from JS must + propagate to the Node backend (so it can `Sentry.init()` and + register `onRequestHook`) and to native (so iOS/Android crash + reporters can be enabled). + +--- + +## 3. Layered architecture + +There are three independent Sentry scopes to manage. They share a +DSN and a release tag, but each runs in its own process / runtime +and needs its own SDK init. + +``` +┌──────────────────────────── Host app ─────────────────────────────┐ +│ │ +│ ┌─────────────── React Native (JS) ────────────────┐ │ +│ │ @sentry/react-native │ │ +│ │ - JS errors, native crashes (iOS+Android) │ │ +│ │ - starts trace for RPC calls │ │ +│ │ │ │ +│ │ @comapeo/core-react-native: │ │ +│ │ - state.on('stateChange', ERROR) → captureException │ +│ │ - state.on('messageerror', ...) → captureException │ +│ │ - comapeo.() wrapper: startSpan + │ │ +│ │ attach sentry-trace + baggage in metadata │ │ +│ └──────────────────────────────────────────────────┘ │ +│ │ │ +│ │ control.sock {type:"init",sentry:…} │ +│ │ comapeo.sock RPC (with sentry-trace) │ +│ ▼ │ +│ ┌─────────────────── Node backend ─────────────────┐ │ +│ │ @sentry/node (bundled, init only on opt-in) │ │ +│ │ - handleFatal → captureException │ │ +│ │ - createMapeoServer({ onRequestHook }) → spans │ │ +│ │ - OpenTelemetry processor sends @comapeo/core │ │ +│ │ spans (PR #1051) to Sentry transport │ │ +│ └──────────────────────────────────────────────────┘ │ +│ │ │ +│ │ shared DSN/release/env │ +│ ▼ │ +│ ┌─────────────────── Native (FGS) ─────────────────┐ │ +│ │ Android: sentry-android via @sentry/react-native│ │ +│ │ iOS: sentry-cocoa via @sentry/react-native │ │ +│ │ - hard crash reports │ │ +│ │ - we forward NodeJSService ERROR transitions │ │ +│ │ with phase tag for correlation │ │ +│ └──────────────────────────────────────────────────┘ │ +└───────────────────────────────────────────────────────────────────┘ +``` + +Key splits: + +- **JS and native** share a single `@sentry/react-native` SDK that + the host app installs and initializes. The module never imports + `@sentry/react-native` directly; it accepts a Sentry-shaped + adapter object that the host hands in (see §4.1). +- **Node backend** runs a separate `@sentry/node` SDK, initialized + inside the bundle.

The main barrel +(`@comapeo/core-react-native`) keeps no Sentry imports and the +adapter type is the only thing pulled into typecheck for those +that do opt in. + +### 4.2 Plumbing the backend config + +The Node backend can't read `process.env` from the host RN app — +it's a separate JS runtime. The control socket already carries the +boot handshake; we extend the existing `init` frame: + +```js +// Native → Node +{ + type: "init", + rootKey: "", + sentry: { // new, optional + dsn: "https://…", + environment: "production", + release: "1.4.2", + sampleRate: 1.0, + tracesSampleRate: 0.1, + rpcArgsBytes: 0 + } +} +``` + +Why piggyback on `init` rather than a separate frame: +- Init is already a one-shot, validated frame + (`backend/index.js:57-103`). Adding an optional sibling field + costs ~10 lines of validation. +- Sentry init must complete **before** `MapeoManager` is + constructed (so span context is available for any boot-time + spans we add) and **before** `ComapeoRpcServer.listen` (so the + `onRequestHook` is registered). The current init handler is the + exact moment we need. +- The control socket is already AF_UNIX local; the DSN never + hits the wire outside the device. + +The native side reads the DSN/environment/release from a +platform-specific source. The simplest path: `configureSentry()` +stashes the backend config into `state` (or a sibling), and +the native module reads it back when it builds the `init` frame. +Specifically: + +- Add a new native bridge method `setSentryConfig(json: string)` + that the JS sub-export calls before the rootkey handshake + completes. Native stores it as a property on `NodeJSService`. +- `NodeJSService.sendInit(rootKey)` includes `sentryConfig` in + the payload if set. + +If `configureSentry()` is called too late (after init has been +sent), we fall back to a separate `sentry-init` control frame +sent post-handshake — the backend's RPC server will then +re-register its `onRequestHook` with the configured Sentry +client. Calls already in flight at that moment are not traced +(documented limitation). + +--- + +## 5. Backend instrumentation (`backend/`) + +Mirrors `comapeo-mobile/src/backend/src/app.js`, adapted to this +module's two-socket boot. + +### 5.1 Bundle strategy + +`@sentry/node` becomes a `dependencies` entry of `backend/package.json` +and gets rolled into the bundle. The built backend therefore +contains the SDK whether or not anyone uses it. + +Bundle-size cost: `@sentry/node` core is ~150–250 KB minified + +gzipped depending on integrations imported. Acceptable for the +APK/IPA but not zero. Mitigations: + +- Subpath-import only what we need + (`@sentry/node/init`, `@sentry/core`) rather than the full + default bundle. We do **not** want HTTP / Express / undici + auto-instrumentation in this Node — the only network surface + is the local fastify on 127.0.0.1. +- Exclude OTLP exporters; the only transport we need is the + Sentry HTTPS transport that ships in `@sentry/node`. +- Confirm rollup can tree-shake; if not, the bundle plugin + config in `backend/rollup.config.ts` may need an explicit + `external: []` adjustment. + +A future optimisation if size matters more than build simplicity +(§9.2): produce a second backend bundle with Sentry stripped, and +have the native module pick which assets dir to copy into +`nodejs-project/` based on host-app config. Not in v1. + +### 5.2 `Sentry.init()` location + +In `backend/index.js`, before any other side-effecting import that +might throw and before `controlIpcServer.listen()`: + +```js +// backend/index.js (sketch) +import * as Sentry from "@sentry/node"; + +let sentryActive = false; + +function initSentry(config) { + Sentry.init({ + dsn: config.dsn, + environment: config.environment, + release: config.release, + sampleRate: config.sampleRate ?? 1.0, + tracesSampleRate: config.tracesSampleRate ?? 0, + integrations: [ + // Keep this list explicit — auto-discovery pulls in + // http/express/etc. that we don't want. + Sentry.consoleLoggingIntegration(), + ], + // tag every event so we can split JS vs native vs backend + // in Sentry's UI. + initialScope: { tags: { layer: "backend" } }, + }); + sentryActive = true; +} +``` + +The `init` handler in `controlIpcServer` calls `initSentry` if the +frame includes a `sentry` field, before resolving `initPromise`: + +```js +init: (message) => { + // … existing rootKey validation … + if (message.sentry) { + try { initSentry(message.sentry); } + catch (e) { console.error("Sentry init failed", e); } + } + resolveInit(rootKey); +} +``` + +### 5.3 Error capture wiring + +Three failure surfaces in `backend/index.js` to retrofit: + +1. **`handleFatal(phase, error)`** — already the single funnel for + uncaught exceptions, unhandled rejections, and boot-phase + throws (`listen-control`/`init`/`construct`/`runtime`). Add: + + ```js + if (sentryActive) { + Sentry.captureException(err, { + tags: { phase, layer: "backend" }, + }); + // Ensure the event is flushed before process.exit(1). + await Sentry.flush(100).catch(() => {}); + } + ``` + + The 100 ms flush window aligns with the existing + `broadcastError` flush — both run inside the same + pre-exit window, in parallel. + +2. **`error-native` handler** — frames forwarded from Android + FGS-local failures (rootkey, watchdog) reach `handleFatal` + with the FGS-supplied phase, so they get captured by #1 + automatically. We add a `tags: { source: "native" }` so + Sentry can filter cross-process forwarding. + +3. **Per-RPC errors** — handled in §5.4. + +### 5.4 RPC tracing — server side + +Replicates the `onRequestHook` from +`comapeo-mobile/src/backend/src/app.js`, called from +`backend/lib/comapeo-rpc.js`: + +```js +// backend/lib/comapeo-rpc.js (sketch) +import * as Sentry from "@sentry/node"; + +export class ComapeoRpcServer extends ServerHelper { + constructor(manager, { sentry } = {}) { + super((socket) => { + const messagePort = new SocketMessagePort(socket); + messagePort.start(); + const server = createMapeoServer(manager, messagePort, { + onRequestHook: sentry ? makeSentryRequestHook() : undefined, + }); + messagePort.on("close", () => server.close()); + }); + } +} + +function makeSentryRequestHook() { + return (request, next) => { + const sentryTrace = request.metadata?.["sentry-trace"]; + const baggage = request.metadata?.baggage; + return Sentry.continueTrace({ sentryTrace, baggage }, () => + Sentry.startSpan( + { + op: "rpc", + name: request.method.join("."), + forceTransaction: true, + attributes: { + "rpc.method": request.method.join("."), + // args intentionally omitted unless rpcArgsBytes>0 + }, + }, + async (span) => { + try { + await next(request); + span.setStatus({ code: 1, message: "ok" }); + } catch (error) { + span.setStatus({ code: 2, message: "internal_error" }); + Sentry.captureException(error, { + tags: { layer: "backend", op: "rpc" }, + }); + throw error; + } + }, + ), + ); + }; +} +``` + +Differences from the comapeo-mobile reference: + +- The hook is only registered when Sentry is active; absent + config, `createMapeoServer` is called without + `onRequestHook` and there is zero overhead. +- We rethrow after `captureException` so the IPC error path + still returns a rejection to the JS caller. The reference + swallows it inside `startSpan`'s callback, which silently + resolves the RPC promise — that loses error visibility + on the JS side. +- `request.args` is not serialized by default. In CoMapeo data + the args can be project-scoped content (observation fields, + attachments). PII risk is high, so opt-in only via + `rpcArgsBytes`. + +### 5.5 OpenTelemetry forwarding (PR #1051) + +When `comapeo-core` PR #1051 merges, `@comapeo/core` will emit +OpenTelemetry spans through the global `@opentelemetry/api` +provider. `@sentry/node` v8+ is built on OpenTelemetry: spans +emitted via `@opentelemetry/api` are picked up automatically by +the Sentry span processor. + +Concretely, after `Sentry.init()`, no further wiring is needed — +`@comapeo/core`'s spans become children of the active Sentry +transaction (the RPC span from §5.4) and ship to the configured +DSN. + +If PR #1051 lands before this integration, we should verify the +parent span linkage in a manual smoke test (see §10). + +--- + +## 6. JS / RN module instrumentation (`src/`) + +### 6.1 New files + +- `src/sentry.ts` — public sub-export. Exposes + `configureSentry()`, types, and the wrapped client. +- `src/sentry-internal.ts` — module-private state holding the + active adapter (or `null`), keyed reads for the RPC wrapper. + +The main barrel (`src/index.ts`) is unchanged so consumers who +don't import the sub-export get no Sentry types or runtime code +linked in. + +### 6.2 RPC client tracing — request side + +The existing `comapeo` client is created once at module load: + +```ts +// src/ComapeoCoreModule.ts:71-72 +const messagePort = new CoreMessagePort() as unknown as MessagePort; +export const comapeo: MapeoClientApi = createMapeoClient(messagePort); +``` + +To attach `sentry-trace` + `baggage` headers as `request.metadata` +on outgoing RPC frames, we have two options: + +**Option A — IPC-level metadata factory** (preferred) + +`@comapeo/ipc/client.js` already supports `request.metadata` on +the wire (the server reads it in `onRequestHook`). If +`createMapeoClient` accepts (or can be extended to accept) a +`getMetadata(method)` option, we register one that returns the +current trace headers from the active Sentry adapter: + +```ts +// src/ComapeoCoreModule.ts (changed) +import { activeAdapter } from "./sentry-internal"; + +export const comapeo: MapeoClientApi = createMapeoClient(messagePort, { + getMetadata: () => { + const a = activeAdapter(); + if (!a) return undefined; + // Sentry v8 helper that returns sentry-trace + baggage. + const { "sentry-trace": st, baggage } = a.getTraceData(); + return st ? { "sentry-trace": st, baggage } : undefined; + }, +}); +``` + +Verify whether the installed `@comapeo/ipc` (currently `^8.0.0`) +exposes such a hook. If it doesn't, file an upstream issue and +fall back to Option B for the interim. + +**Option B — Method proxy wrapper** + +`configureSentry` returns a Proxy-wrapped clone of `comapeo` +where each method call: +1. Starts a `Sentry.startSpan({ op: "rpc.client", name: ... })`. +2. Reads `getTraceData()` for headers. +3. Calls the underlying `comapeo` method with a wrapped first + argument that smuggles the headers — but this only works if + the IPC supports per-call metadata, which collapses Option B + into Option A. + +If neither path is possible without an upstream change to +`@comapeo/ipc`, we accept JS-side spans without distributed +tracing for v1 (the backend still produces its own spans, just +unlinked) and pursue the IPC change as a follow-up. + +### 6.3 State observer capture + +`state` already surfaces every error condition the JS layer +sees. `configureSentry()` registers two listeners: + +```ts +state.addListener("stateChange", (s, info) => { + if (s !== "ERROR" || !info) return; + const e = new Error(info.errorMessage); + e.name = `ComapeoError:${info.errorPhase}`; + adapter.captureException(e, { + tags: { + layer: "rn", + "comapeo.phase": info.errorPhase, + "comapeo.state": s, + }, + }); +}); + +state.addListener("messageerror", (err) => { + adapter.captureException(err, { + tags: { layer: "rn", source: "control-socket" }, + level: "warning", + }); +}); +``` + +Phase tags align with the values produced in +`src/ComapeoCore.types.ts` and the native sources +(`rootkey`, `node-runtime-unexpected`, `shutdown-timeout`, +`starting-timeout`, `ipc`, `listen-control`, `init`, +`construct`, `runtime`). They become Sentry filterable tags so +the team can dashboard "rootkey load failure rate" or "FGS +watchdog timeout rate" without parsing message strings. + +### 6.4 Public client error capture + +The IPC client surfaces RPC errors as rejected promises. Most +captures happen on the backend side (§5.4) and reach Sentry from +there with full context. The JS side adds a thin +`captureException` for client-perceived errors (e.g. RPC timeouts, +disconnect mid-call) that the backend never observed: + +```ts +// inside the wrapper or proxy from §6.2 +async (...args) => { + return Sentry.startSpan({ op: "rpc.client", name: method }, async () => { + try { + return await underlying[method](...args); + } catch (e) { + // Only capture if it didn't originate from a backend + // event we already see in §5.4 — the backend tags its + // captures with `layer: "backend"`. Backend RPC failures + // arrive here as plain errors, but Sentry de-dupes if + // the same exception is captured twice with different + // contexts. Acceptable. + Sentry.captureException(e, { + tags: { layer: "rn", op: "rpc.client", "rpc.method": method }, + }); + throw e; + } + }); +} +``` + +--- + +## 7. Native instrumentation (`ios/`, `android/`) + +The host app's `@sentry/react-native` already configures the +underlying `sentry-cocoa` and `sentry-android` SDKs for the main +process. What's left for this module: + +### 7.1 Forwarding the backend Sentry config + +A new bridge method on the Expo module: + +- iOS: `ComapeoCoreModule.swift::Function("setSentryConfig", …)` + → calls `nodeService.setSentryConfig(json)`. +- Android (main app process): same function, forwards the JSON + to the FGS via an Intent extra on `startService`. + +The `NodeJSService` on each platform stores the JSON and +embeds it in the `init` frame (§4.2). + +### 7.2 Android FGS process + +The FGS runs in the `:ComapeoCore` process — see +`ARCHITECTURE.md §2.2`. `Sentry.init()` in the host app's +`MainApplication` runs only in the main process; the FGS process +gets a fresh `Application` and needs its own init. + +Two options: + +1. **Host-app responsibility.** Document that the host app's + `MainApplication.onCreate` should detect the FGS process and + call `SentryAndroid.init(...)` with the same DSN there. + `@sentry/react-native` does not handle multi-process + automatically. +2. **Module convenience.** Add a helper + `ComapeoCoreInit.installSentryInFgs(application, options)` that + the host calls from its `MainApplication`. The helper detects + `getProcessName().endsWith(":ComapeoCore")` and conditionally + inits `SentryAndroid`. + +Option 2 keeps the cross-process detail inside the module that +introduced the second process. Recommended. + +### 7.3 Native error tagging + +When `NodeJSService` enters ERROR locally (rootkey load, +watchdog), it already populates `_lastError` and emits +`stateChange`. The module emits a JS-visible event that §6.3 +captures, but on Android FGS that capture happens in the main +process — the FGS's own context (logcat tail, foreground state, +notification ID) is in the *FGS* process's Sentry scope. + +If the FGS-side Sentry SDK is initialised (§7.2 option 2), we +also call `SentryAndroid.captureException` from the FGS error +handler, tagged `proc:fgs phase:`, before we forward the +`error-native` frame to Node. The duplicate event (FGS-side + +backend-side via `error-native` re-broadcast + main-process JS-side +via `stateChange`) is deduplicated by Sentry's fingerprinting and +gives us all three vantage points. + +iOS doesn't need this — the FGS doesn't exist there, everything +runs in the host app process and the host app's +`@sentry/react-native` already covers it. + +### 7.4 Hard-crash reporting + +Crashes that bypass JS (SIGSEGV in a native addon, OOM kill, +`process.abort()`) are documented in `ARCHITECTURE.md §6` as +"belong in a separate channel". `sentry-cocoa` and +`sentry-android` already handle native crashes for the host app +process; on Android the FGS process needs its own init (§7.2) +to capture FGS-process crashes. + +We do not bundle `sentry-native` into the embedded `nodejs-mobile` +runtime. A V8 abort or libnode crash will not produce a Sentry +event from inside Node — but it will produce an Android-process +crash (since the FGS process dies) which `sentry-android` will +capture with a stacktrace from the JNI side. + +--- + +## 8. PII, sampling, and privacy + +CoMapeo data is sensitive (observation locations, attachments, +device identities). Defaults must avoid leaking it into Sentry: + +- **`request.args` is never serialized** unless + `rpcArgsBytes > 0` is explicitly set. Method names and + metadata only. +- **No project IDs in span names**; only RPC method paths + (`project.observation.create`, etc.). If we later want + per-project breakdowns, hash the project ID before adding + it as a tag. +- **No rootkey, no public/secret keypair, no observation + contents** in event payloads. The `error-native` frame + carries phase + message; the backend `Sentry.captureException` + call does too. +- **Stacktraces** are fine — they may include filenames from + inside `@comapeo/core` and the bundled backend. No user data + unless an `Error.message` was constructed with one (audit + these on integration). +- **`tracesSampleRate`** defaults to `0` if unspecified.

Native reads those at process start, no JS round-trip, before booting @sentry/node and @sentry/android. - §7.4 added: native telemetry data design mapped onto Sentry primitives (breadcrumbs for state transitions, transaction + spans for boot/shutdown phases, captureMessage for timeouts, tags/contexts for cross-process attribution). Categorizes captures as essential vs opt-in and documents a hard never-capture list for PII. - §9 added: persisted "capture application data" toggle with restart-to-activate semantics. Snapshot read at boot, embedded in the init frame; gates per-RPC spans, sync-session transactions, memory checkpoints, and storage-size sampling. Never unlocks the never-capture list. - §10 phasing and §13 file-change list updated.

Allows the FGS process to capture native + crashes, ANRs, and the §7.4 telemetry events with the same DSN. + On iOS the host app's `@sentry/react-native` already owns the + single-process SDK; we don't re-init. +2. **Backend init frame.** When `NodeJSService.sendInit(rootKey)` + builds the `init` frame, it embeds `SentryConfig` as a + `sentry` field (see §4.5).

That convention is CoMapeo-specific and shouldn't be hard-coded in this module. Consumers feed `environment` via app.config.js + EAS build-profile env vars (SENTRY_ENVIRONMENT). The plugin requires `dsn` and `environment`; `release` defaults to versionName at runtime. - §4.5 + §5: replace control-socket init-frame transport with Node argv at spawn time. Sentry config in argv satisfies the auto-instrumentation order requirement (Sentry.init must run before any module loads so import-in-the-middle can patch them).

Confirm the host - app's `@sentry/react-native` config doesn't override our tag - in the main-process events. -6. **Release tagging via plugin**: §4.1 has the consumer pass - `release` as a literal in `app.json`. CoMapeo Mobile likely - wants this auto-derived from the host app's version. The - plugin can read `config.version` (the consumer's `expo.version`) - as a default; a `${VERSION}` placeholder is another option. - Decide which. -7. **Plugin output for empty config**: when the consumer - registers the plugin without a `sentry` argument (e.g. just - `["@comapeo/core-react-native"]`), the plugin should be a - no-op for Sentry. Confirm we don't accidentally write empty - `` entries that confuse the native loader. -8. **Toggle UI surface**: where does the host app expose the - `setCaptureApplicationData` switch? CoMapeo Mobile already - has a settings screen — coordinate the copy and restart - prompt. Out of scope for this module but called out for - integration. -9. **Boot transaction sample rate**: §7.4.2 forces 100% on boot - even when overall `tracesSampleRate` is low. Confirm this - doesn't blow Sentry quota for high-launch-volume users. - May need a 1-in-N sampler with a minimum floor. -10. **Sourcemap upload for the backend bundle**: §5.1 mentions - `@sentry/rollup-plugin` for sourcemap upload. Confirm CI - has `SENTRY_AUTH_TOKEN` available and that uploaded - sourcemaps reference the right release tag (matching - what native passes as `--sentryRelease`). -11. **Lazy chunk on iOS**: nodejs-mobile on iOS runs V8 with - `--jitless`. Confirm dynamic `import()` works there for - a separate ESM chunk; the mainline path is well-tested - but the lazy path is new code. iOS is also where we - already stub the `@comapeo/core` maps plugin to keep - undici out (see `backend/lib/maps-stub.js` and the - `stubComapeoMapsPlugin` in `rollup.config.ts`); the - Sentry chunk is an additional surface for this kind of - iOS-only quirk. -12. **Offline transport**: comapeo-mobile uses - `sentry-offline-transport-better-sqlite` to queue events - while offline. Decide whether v1 ships offline transport - or accepts dropped events when the device is offline. - Mobile fieldwork is offline more than online; this is - likely required for production usage but adds another - bundled dep. -13. **Capture-application-data toggle and EAS development - builds**: development builds are presumably - `environment: "development"` and frequently want - detailed traces. Consider whether the toggle should - default to `true` for non-production environments - (read from the manifest at startup), so developers - don't have to flip it in their settings UI on every - fresh install. Defaulting to `false` everywhere is - safer; defaulting to `true` for `environment !== - "production"` is more useful. Decision pending. +## 12. Decisions and remaining questions + +### 12.1 Decided + +| Question | Decision | +|---|---| +| Sentry SDK versions | `@sentry/node@^8`, `@sentry/react-native@^6`, `@sentry/core@^8`. OpenTelemetry-first majors so PR #1051 forwarding works without glue (§5.1). | +| `@comapeo/ipc@^8` client-side hook | Confirmed: `createMapeoClient` accepts `onRequestHook` directly. Pattern lifted from [`comapeo-mobile/src/frontend/lib/createMapeoApi.ts`](https://github.com/digidem/comapeo-mobile/blob/develop/src/frontend/lib/createMapeoApi.ts) (§6.2). | +| `release` source | Default to `versionName + "+" + versionCode` (Android) / `CFBundleShortVersionString + "+" + CFBundleVersion` (iOS). Successive EAS builds of the same marketing version produce distinct releases. Plugin override always wins (§4.1). | +| Boot transaction sample rate | Force 100% even when overall `tracesSampleRate` is low. Boot is once-per-process and high-value. Document quota implications (§7.4.2). | +| Bundle size strategy | Single bundle with rollup chunk-splitting — accept the disk cost. No dual-bundle build for v1 (§5.1). | +| Plugin behaviour with no `sentry` arg | No-op silently. Treat absent meta-data / plist keys as Sentry off. Used by `apps/example/` (§4.1). | +| Sourcemap upload | Consumer responsibility. Module ships `*.map` in npm package; consumer excludes from APK/IPA and runs `sentry-cli sourcemaps upload` against `node_modules/.../nodejs-project/` in their own CI with their own credentials (§5.1). | +| Toggle UI surface | Out of scope for this module. Module exposes `getCaptureApplicationData` / `setCaptureApplicationData` only; consumer builds the settings UI and the restart prompt (§9.2). | +| Capture-application-data default | Per-environment, decided by consumer at build time via `captureApplicationDataDefault` plugin field. EAS env var pattern: default to `true` when `environment !== "production"`. Once user flips the switch their explicit choice wins (§9.7). | + +### 12.2 Still open / verify-during-build + +1. **Cross-process scope on Android**: Phase 2 smoke test must + verify FGS-process Sentry events carry `proc:fgs` and that + `@sentry/react-native`'s main-process tags don't override + them in the dashboard. +2. **Lazy chunk on iOS `--jitless`**: dynamic `import()` of a + separate ESM chunk should work but isn't proven for our + specific config.

The native-side direct-Sentry-SDK init in the FGS process and the breadcrumb/span/event calls remain deferred to Phase 2b — they need a Gradle dep on io.sentry:sentry-android-core, scoped out of this PR. Phase 1 (JS-side adapter): - src/sentry-internal.ts holds the active SentryAdapter slot. Phase 3 RPC tracing reads from it. - src/sentry.ts exposes configureSentry({ sentry }) as the public API. SentryAdapter is hand-rolled (not Pick) so consumers without the optional peer dep don't get a typecheck error. State listeners emit a comapeo.state breadcrumb on every transition and a captureException tagged ComapeoError: on ERROR. messageerror events capture as warning-level. - package.json gains an exports field (./, ./sentry, ./app.plugin) and lists @sentry/react-native@^6 as an optional peer dep. Phase 2a (config plugin + native readers): - app.plugin.js (root) is an ESM Expo plugin (the package is type:module). withAndroidManifest upserts on the main ; withInfoPlist upserts plist keys. Validates dsn+environment at prebuild. No-op when registered without a sentry argument. - SentryConfig.kt + SentryConfigTest.kt land the typed manifest reader. Pure load(metaString, defaultRelease) overload makes the parser unit-testable on the JVM classpath without mocking android.os.Bundle. Default release = versionName + "+" + longVersionCode (API 28+) so successive EAS builds disambiguate. - SentryConfig.swift + SentryConfigTests.swift mirror the Android side.

The FGS process (`:ComapeoCore`) gets its own Sentry SDK init because the host's `@sentry/react-native` only fires in the main process. Without this, FGS-originated errors carry no logcat tail / foreground-state context and the boot transaction is unobservable from the dashboard. What's new on Android: - `io.sentry:sentry-android-core:7.20.1` added as `compileOnly` + `testImplementation`. The runtime classes come transitively from `@sentry/react-native@^6` — consumers without Sentry pay nothing. - `SentryFgsBridge.kt` (guard) + `SentryFgsBridgeImpl.kt` (impl) split. The guard's `Class.forName` probe (with `initialize=false` so the SDK's `` doesn't run on the JVM unit-test classpath) gates every public method. Impl freely imports `io.sentry.*` and is only loaded when the guard says the SDK is present. - `ComapeoCoreService.onCreate` calls `SentryFgsBridge.init(applicationContext, cfg)` from `SentryConfig.loadFromManifest(...)`. Sets `proc:fgs` and `layer:native` as process-level tags so dashboards can split FGS events from the main-process events that carry `proc:main` from `src/sentry.ts`. - `NodeJSService` opens `comapeo.boot` transaction in `start()`, closes on first STARTED (`ok`) / ERROR (`internal_error`). Phase spans (`boot.rootkey-load`, `boot.init-frame`) match the bench backend's taxonomy from `apps/benchmark/backend/lib/boot-spans.js` on `claude/benchmark-uds-rpc-bridge-1Zahz` so a single Sentry dashboard query charts both sides. - State-transition breadcrumbs in `applyAndEmit`, control-frame breadcrumbs (started/ready/stopping/error/ malformed) in `handleControlMessage`, FGS lifecycle breadcrumbs (`onCreate`/`onStartCommand`/`onDestroy`). - Timeout events (`comapeo: startup timeout fired`, `comapeo: FGS stop timeout fired`) tagged `timeout:startup` / `timeout:fgsStop`. - FGS-side `captureException` on rootkey-load failure tagged `comapeo.phase:rootkey`, `source:rootkey-store`. Fires before `sendErrorNativeFrame` so the FGS scope is intact; the same exception is re-broadcast and re-captured by the main-process JS adapter for the cross-process triple per §7.4.7. Phase 1 polish: added `proc:main` to the JS adapter's `captureException` calls so the pair with `proc:fgs` is filterable in the dashboard. Tests: - `SentryFgsBridgeTest.kt` pins the no-op guard contract: pre-init calls (addBreadcrumb / captureException / captureMessage / startBootTransaction / startBootSpan / finishSpan) all return cleanly; the `Class.forName` probe with `initialize=false` finds sentry-android on the test classpath and is idempotent. - `eslint.config.js` ignores `.claude/**/*` so leftover worktree artifacts don't break the lint cache. Verified locally: - `npm run lint` clean - `npx tsc --noEmit` clean - `./gradlew :comapeo-core-react-native:testDebugUnitTest` passes (54 tests, including 9 new SentryFgsBridge cases) - `./gradlew :comapeo-core-react-native:compileDebugKotlin` succeeds with sentry-android on the compile classpath Plan + README updated: - §10.2 Phase 2b reframed as "landed (Android only)" with full implementation list + iOS-deferred note. - §13 file-change list reflects what shipped. - README "Optional: Sentry integration" gains a "What gets captured automatically" section explaining the three event streams (JS/main, FGS/native, backend later) and the automatic FGS-process SDK init. --- README.md | 29 +++ android/build.gradle | 17 ++ .../com/comapeo/core/ComapeoCoreService.kt | 46 ++++ .../java/com/comapeo/core/NodeJSService.kt | 188 +++++++++++++- .../java/com/comapeo/core/SentryFgsBridge.kt | 236 ++++++++++++++++++ .../com/comapeo/core/SentryFgsBridgeImpl.kt | 166 ++++++++++++ .../com/comapeo/core/SentryFgsBridgeTest.kt | 133 ++++++++++ docs/sentry-integration-plan.md | 157 +++++++++--- eslint.config.js | 6 +- src/sentry.ts | 21 +- 10 files changed, 951 insertions(+), 48 deletions(-) create mode 100644 android/src/main/java/com/comapeo/core/SentryFgsBridge.kt create mode 100644 android/src/main/java/com/comapeo/core/SentryFgsBridgeImpl.kt create mode 100644 android/src/test/java/com/comapeo/core/SentryFgsBridgeTest.kt diff --git a/README.md b/README.md index b57182f..7d9f12b 100644 --- a/README.md +++ b/README.md @@ -128,6 +128,35 @@ events are captured to your Sentry project tagged with the relevant phase (`rootkey`, `starting-timeout`, `node-runtime-unexpected`, etc.).

Span op/description ordering (was: review #19) - transaction.startChild(op, description) — op is the indexed dashboard column. Was passing ("boot", "boot."), swapped to ("boot.", human-readable description) so the dashboard groups by the phase taxonomy that matches the bench backend's boot-spans.js helper. Plugin idempotency (was: review #7) - Previously, dropping `props.sentry` from the plugin registration left stale meta-data / plist entries from a previous prebuild (with `expo prebuild --no-clean`). Plugin now passes through a no-Sentry cleanup mod that strips every key it owns; consumer-owned keys (e.g. io.sentry.* set by @sentry/react-native's plugin) are untouched. messageerror payload truncation (was: review #8) - src/sentry.ts now truncates the wrapped error message to 256 chars before forwarding to captureException. The control-frame parser surfaces offending input verbatim, which can include arbitrary bytes from a corrupted frame — truncating keeps Sentry events small and readable. IPC + SEND_ERROR_NATIVE breadcrumbs/events (was: review #9, #10) - NodeJSIPC's onConnectionStateChange callback wired in the FGS-side controlIpc construction; emits comapeo.ipc breadcrumbs at info (warning on Error). Per §7.4.5. - SEND_ERROR_NATIVE_TIMEOUT_MS firing now captures a level=warning event with timeout:errorNativeForward tag. Per §7.4.4. Logging swallowed surprises (was: review low-priority) - SentryFgsBridge's empty `catch (t: Throwable) {}` blocks now Log.w so debug builds notice swallowed bridge / SDK bugs. Post-init bridge tests (was: review #6) - New SentryFgsBridgeImplTest spins up a real Sentry hub via the cross-platform Sentry.init(SentryOptions) path with an in-memory ITransport.
