Conversation
…p path MAESTRO-YV: `contextTimeline:getCaptures` / `contextTimeline:clearCaptures` were never registered in a shipped build, so every renderer call rejected with "No handler registered". `registerContextTimelineHandlers` was imported into `src/main/ipc/handlers/index.ts` and added to `registerAllHandlers()`, which reads like the authoritative registration list but is dead - nothing calls it. The live path is `setupIpcHandlers()` in `src/main/ipc/bootstrap/index.ts`, which `main/index.ts` invokes at app-ready. The registrar was also never re-exported from `handlers/index.ts`, so the bootstrap file could not reach it. Impact: the Context Timeline panel hydrated empty on every window reload, second window, and web-desktop client - exactly what #1365 set out to fix. `forgetContextTimelineCaptures` fires `clearCaptures` as a floating `void` promise, so its rejection surfaced as an unhandled rejection in Sentry. The existing handler unit test calls `registerContextTimelineHandlers()` directly, so it stayed green while production was broken. The new test reads both sources and asserts the invariant that actually held wrong: a registrar invoked by the dead list must also be invoked by the live one. Both cases were confirmed red against the unfixed source.
📝 WalkthroughWalkthroughThe change exports ChangesIPC handler wiring
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new regression test currently treats an intentionally unreachable handler wrapper as a live registrar, so it fails instead of validating the intended bootstrap wiring.

Greptile SummaryThis PR wires the existing Context Timeline IPC registrar into the live main-process bootstrap and re-exports it from the handler barrel.
Confidence Score: 4/5The runtime fix appears safe to merge, but the regression test should parse or isolate the registration function bodies so unrelated source text cannot determine its result. The Context Timeline registrar now has one reachable startup invocation with no duplicate live registration path; the only accepted concern is the non-blocking fragility of the source-scanning test.

There was a problem hiding this comment.
invokedRegistrars scans entire source files and counts function declarations and comments as calls. The current sets include the registerAllHandlers declaration from the handlers file and a comment mentioning registerAllHandlers() from the bootstrap file, so unrelated comment changes can fail the test and registrar-shaped comments can hide missing live registrations.
Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Exclude the registerAllHandlers definition from the registrar set.
Line 39 matches registerAllHandlers( in the function declaration in src/main/ipc/handlers/index.ts. The test then requires the live bootstrap to invoke that dead wrapper. Lines 53-54 fail because setupIpcHandlers() intentionally does not call it.
Proposed fix
function invokedRegistrars(filePath: string): Set<string> {
const source = readFileSync(filePath, 'utf-8');
const names = source.match(/register[A-Za-z]+Handlers\(/g) ?? [];
- return new Set(names.map((n) => n.slice(0, -1)));
+ return new Set(
+ names
+ .map((n) => n.slice(0, -1))
+ .filter((name) => name !== 'registerAllHandlers')
+ );

Eleventh Sentry triage pass,

I pinned the query to
release:0.18.5-RC(=package.jsonatorigin/rcHEAD), which is the decisive main-vs-rc filter. That returned 18 aggregate rows. Exactly one of them was a live, clearly-fixable defect in current rc code, so this PR is deliberately small.Fixed: MAESTRO-YV
Error invoking remote method 'contextTimeline:clearCaptures': No handler registered for 'contextTimeline:clearCaptures'-environment: production,channel: rc, release0.18.5-RC.Root cause. There are two registration lists:
registerAllHandlers()insrc/main/ipc/handlers/index.ts- reads like the authoritative list, but nothing calls it. Its only mention anywhere is inside a comment.setupIpcHandlers()insrc/main/ipc/bootstrap/index.ts- the live path, invoked frommain/index.tsat app-ready.registerContextTimelineHandlerswas imported intohandlers/index.tsand added to the dead list only. It was also never re-exported from that module, sobootstrap/index.tscould not have called it even if someone tried.Net effect: neither
contextTimeline:getCapturesnorcontextTimeline:clearCaptureswas ever registered in a shipped build.Timeline corroborates it. The feature landed in
07b5ac381(#1365, 2026-08-10); MAESTRO-YV's first event is 2026-08-11.User-visible impact. The Context Timeline panel hydrated empty on every window reload, every second window, and every web-desktop client - precisely the problem #1365 set out to fix.
hydrateContextTimelinetreats a failed fetch as "not hydrated" and returns quietly, sogetCapturesfailed invisibly.forgetContextTimelineCapturesfiresclearCapturesas a floatingvoidpromise with no.catch(), so only that half surfaced, as an unhandled rejection.Fix. Re-export the registrar and call it in
setupIpcHandlers(), next toregisterTabsHandlers().Regression test
src/__tests__/main/ipc/bootstrap/handler-wiring.test.ts.The existing
context-timeline.test.tscallsregisterContextTimelineHandlers()directly, so it passed 100% while production was broken - the same "a permissive test harness hides exactly the bug you are chasing" failure mode as the duplicate-ipcMain.handlefinding in #1341.So the new test does not re-test the handler. It reads both sources and asserts the invariant that actually held wrong: every registrar invoked by the dead
registerAllHandlersmust also be invoked by the livesetupIpcHandlers. That catches the whole bug class, not just this instance. It includes a floor assertion on the extracted count so a regex that silently stops matching fails loudly rather than passing vacuously.Both cases confirmed red against the unfixed source before the fix, green after.

Per the dead-code-hygiene rule, listing rather than deleting:
registerAllHandlers()(handlers/index.ts:219, 38 registrars) - unreachable, and it is the trap that caused this bug: it looks like the registration list, so a new handler gets added there. This PR makes the two lists consistent, and the new test keeps them consistent, but deleting it would remove the trap outright.
