The renderer is not a copy: both TraceSift's +web page and this plugin import the same components from +`@callstack/tracesift-explore`, so a drill-down cannot drift from the app that +produced the numbers. + +The card's frame cannot reach the TraceSift service — Codex strips plain HTTP +origins from widget CSP — so its data rides MCP like everything else here. +`mobile_tracesift_explore_payload` fetches `/api/integration/v1/task` or +`/api/integration/v1/react-explore` with the service bearer token and returns the +payload as one text item plus a small `structuredContent` envelope +(`apiVersion`, `kind`, `encoding`, `payloadBytes`). A full task card carries its +whole call tree and timeline, which runs to megabytes, so past 64 KiB the text is +gzip-compressed base64; a measured 25 MB tree crosses in about 8 ms at a fifth +of its JSON size. Below that threshold it stays plain JSON. Keeping the tree out +of structured content avoids the deep-structured-payload failure documented +above: the SDK and host validate only the envelope, and the iframe inflates and +parses the payload once into the shapes the explorer draws. Payloads above +24 MiB are refused before decoding and point at the browser window; the service +already caps its trees at 60k nodes and 5k commits. Payload size is reported as +`tracesift.explore.payload_bytes`, which is where an oversized tree shows up +before a reader reports a spinner. + +The same rule applies to the payload's age: it is fetched from the live service, +so an expired analysis answers with the existing "run it again" error instead of +a half-drawn tree. **Open in browser** keeps the previous path, which hands the +selection to `tracesift explore`. + +Version skew favours the reader's installed service: payloads are additive-only +within integration API v1, the explorers ignore fields they do not know, and an +older service that cannot answer the endpoint fails with an update message. The +plugin folds the package's one compiled stylesheet into its single HTML bundle, +after the plugin's own Tailwind layer, so neither build compiles the other's +sources. That sheet opens by writing its theme tokens to `:root` and `.dark`, +which would recolor the plugin's cards behind the explorer, so the fold scopes +both token blocks to `.tracesift-explore` — descendants inherit the custom +properties, and a block that no longer has the shape the fold expects fails the +build rather than leaking globally. During development the package is wired in +with a local `file:` link; the build then resolves its imports from this +project's install whenever the versions agree, so the bundle never carries a +second React or a duplicated copy of a shared library. + ## Sources The implementation follows [Baguette's HTTP and WebSocket routes](https://github.com/tddworks/baguette/blob/v0.2.1/docs/serve.md) and [gesture protocol](https://github.com/tddworks/baguette/blob/v0.2.1/docs/wire.md).

Since Explore renders in-panel, the older meaning of `ui.tracesift.explore` (a successful CLI browser launch) now belongs to the `ui.tracesift.explore_browser` counter and its `ui.tracesift.explore_browser` timing and `ui.tracesift.explore_browser_failed` counter. Explorer readiness reuses `ui.surface.ready`, and `tracesift_view` distinguishes `cards` from `explorer` so explorer work is not attributed to the card list; navigating back resets that context.

These measurements describe plugin and local-service work, not the profiled app's performance. The environments are `development` and `release`. `npm run build` and `npm run package` default to `development`, including local installed packages. For a public release, run `npm run build:release` followed by `npm run package:release`. Packaging rejects a build from the other environment. The package stores its environment in `dist/telemetry-environment.json`; Node telemetry, native helpers and the served UI use that setting. Live reload does not determine the environment. Set `MOBILE_DEV_ENVIRONMENT=development` or `MOBILE_DEV_ENVIRONMENT=release` in the MCP launch environment to override explicitly, then restart the MCP processes and reopen the panel. diff --git

Real TaskCard trees measured from perf-ai shapes sit far +below that, but the guard below makes it moot. Chrome's own `JSON.parse` is +iterative for objects since Blink's parser rewrite; the plugin's own +`JSON.parse` in the iframe shares V8's stringify limit only if it re-serializes. + +### What this does NOT model (read before trusting the table) + +- The real Codex host sits between stdio JSON and postMessage. Its + structuredContent decoder reportedly has depth/size limits + (docs/architecture.md ~line 73: a deep runtime tree as structured content + "can cause a host to discard the response and wait until timeout"). This + harness cannot replicate that; only V3 sidesteps it **by construction** + (the host sees a flat string, never a deep object). +- InMemory-style transport ≠ the host's process boundary: the real path adds + at least one more serialize/copy per hop, so absolute wall times here are + lower bounds. Relative ordering between variants should hold. +- Real postMessage uses structured clone (keeps numbers exact, usually faster + than JSON.parse); ext-apps' `PostMessageTransport` also safeParses each + message with `JSONRPCMessageSchema` (result is `z.unknown()`, shallow — fine + at depth; verified not to recurse). +- Peak RSS with all fixtures live hit ~500 MB in this single process; the real + app/server are separate processes, one payload at a time. + +## RECOMMENDATION — transport + +**Ship V3: `content:[{type:'text', text: base64(gzip(json))}]` on an +app-only tool with no outputSchema**, decoded in the iframe with +`DecompressionStream('gzip')` → `JSON.parse`. + +Why V3 over the rest: +- It is the **only variant immune to host structuredContent depth/size + decoders**: the bridge carries a string. That is the phase-0 risk that + motivated the spike; V1/V2 leave it open, V4 only shrinks it to + "base64 string inside a resource" (same string-safety, but 33% bigger and + the resource lifecycle/URI-revision machinery buys nothing for a + one-shot payload). +- Smallest wire by far (5.3 MB vs 25–33 MB at the 25 MB fixture) — least + exposure to any per-message cap anywhere in the host, and fastest wall time + (~8 ms vs 335 ms in-process). +- Total user-perceived cost at 25 MB ≈ server gzip 223 ms + bridge + iframe + decode 133 ms ≈ well under a second — acceptable for an explicit Explore + click, and no variant gets the iframe decode below ~64 ms anyway at 25 MB. + +Belt-and-braces, keep anyway: +- **Flatten server-side: no.** With V3 the tree depth is invisible to the + bridge and both Node and Chrome handle depth 500 (and ≥2000 for parse) + comfortably; flattening would force the perf-ai components (`TaskExplorer` + expects nested `TaskTreeNode`) to fork on shape, breaking parity-by- + construction — the plan's core property. Instead **cap depth server-side** + (see guard) and keep the plugin's flat-array pattern only where it already + exists (UI inspection). +- **Do not define a recursive outputSchema** for the payload tool (stack risk + at ~2000 depth + tools/list conversion cost). Use no outputSchema or + `{ payloadRef: z.string(), bytes: z.number(), encoding: z.string() }`-style + flat metadata beside the text block. + +Proposed max-payload guard (plugin server, `mobile_tracesift_explore_payload`): +1. Reject before fetching if the request would exceed perf-ai's own caps + (60,000 nodes / 5,000 commits) — mirror them server-side. +2. After fetching: raw JSON > **24 MiB** → return `isError` with a + "payload too large, open in browser" result (keep the CLI fallback link). +3. Walk the tree iteratively to measure depth; depth > **1500** → flatten + that response to a parentId array *or* fall back to browser (cheap O(n), + and turns the depth question into a policy instead of a crash class). +4. Always gzip (any payload > ~64 KiB pays ~5 ms/MB, buys 5–7× wire). + Use the async `zlib.gzip` callback form so a 200 ms compression doesn't + stall the MCP server's event loop (it also serves frame streams). +5. Keep the existing `callServerTool` timeout pattern from the other panels + (they pass `{ timeout: 45000 }`) on the view-side call. +6.
