Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds real-daemon end-to-end coverage without changing product runtime behavior. The test can still obscure setup failures or become flaky if the daemon emits enough output to fill its pipes, so merge is reasonable with owner awareness and follow-up on test reliability. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

These three
rt chatcalls discard their result. Ifdmorpostfails, the test still continues and fails later at thetoEqualassertion on Line 232 with a mismatched context string. That hides the real cause.signInalready throws on a non-zero exit code; apply the same treatment here.♻️ Proposed helper

dmcall at Line 247 and togetBuddiesat Line 128, which parses stdout without checking the exit code.🤖 Prompt for AI Agents

96-100: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winDo not leave the daemon's piped stdout and stderr undrained.
runRtalways setsstdout: "pipe"andstderr: "pipe". Short-lived CLI calls go throughfinished(), which drains both streams. The daemon started here is never drained and lives for the whole test. If the daemon writes more than the OS pipe buffer (commonly 64 KB), its writes block and the daemon stalls, which shows up as an intermittent timeout in these 30 s tests.Pass an output mode for the daemon spawn, or drain its streams in the background.
♻️ Proposed change: allow an output mode per spawn
-function runRt(args: string[], homeDir: string, extraEnv: Record<string, string> = {}) { +function runRt( + args: string[], + homeDir: string, + extraEnv: Record<string, string> = {}, + output: "pipe" | "ignore" = "pipe", +) { const bunDir = join(process.execPath, ".."); const proc = Bun.spawn([RT_BINARY, ...args], { @@ - stdout: "pipe", - stderr: "pipe", + stdout: output, + stderr: output, });async function startDaemonForHome(homeDir: string, extraEnv: Record<string, string> = {}): Promise<void> { apiPort = freePort(); - runRt(["--daemon"], homeDir, extraEnv); + runRt(["--daemon"], homeDir, extraEnv, "ignore"); await waitForSocket(join(homeDir, ".mattstack", "rt", "rt.sock")); }The
chat tailprocess at Line 244 has the same exposure, but its output volume is bounded by the single DM in that test.🤖 Prompt for AI Agents

e2e: the chat plugin's pulse hook against a real rt
The plugin's hook scripts were tested only against a stub
rtechoing canned JSON, so the chain from the compiled binary throughrt chat pulse --jsonto the injectedadditionalContextwas correct by inspection, not by test. The final review of the presence work asked for this.What changed
e2e/tests/chat-plugin-hooks.test.ts: runs the plugin's realpulse.shas a subprocess against the compiled binary, under the e2e isolated HOME, with a real daemon and real sign-insRT_CHAT_PLUGIN_DIR, then the two default marketplace paths; skips the file entirely when none exists, so a machine without that checkout is unaffectedVerification
5/5 locally; full gate green (unit 4136, e2e 107, tsc clean, purity clean).
