…liably Three defects on the New Call polling path, each of which let the source skip or repeat calls. The cursor was not the newest call. /v2/calls returns calls ordered by id, not by start time, so `Array.from(resources).reverse()[0]` picked an arbitrary call rather than the most recent. Verified against a live workspace: the batch's true max(started) was 2026-05-20T04:36:25.028Z while the stored cursor was 04:35:39.986Z. When a batch truncates at DEFAULT_MAX the cursor could be taken from an arbitrary member of the truncated set, permanently skipping earlier-starting calls beyond the cap - the reported symptom, reachable with no processing lag at all. The batch is now ordered by `started`, which also makes deploy() emit the 25 most recent instead of an arbitrary 25; it was getting 16 of 25 wrong. The lookback prop was unbounded. `min` without `max` let a large value push Date.now() - lookbackMs outside the range Date accepts, throwing RangeError and aborting the poll: a trigger reporting active: true while emitting nothing. The prop now carries max: 168, and the value is clamped at runtime as well, because the deploy API accepts out-of-range values verbatim - prop min/max are enforced client-side only. Dedupe leaned on a cache smaller than the window. Holding the cursor behind the present means every poll re-reads its window, and dedupe: "unique" remembers only the last 100 ids, which a busy workspace overruns immediately: 83,838 duplicate deliveries over a simulated 24h at high volume. Emitted ids are now tracked in db, pruned to the window the cursor reopens and capped, so repeats are suppressed before $emit rather than after it. Verified live: a poll that re-read 92 calls emitted none of them, and the same 97 calls were still delivered exactly once. State is now written after emitting rather than before, which the source guidelines require and which the ledger depends on - persisting what was emitted before emitting it would drop calls on a partial failure.

Hi @MLuc24, thank you for your contribution! A couple of fixes to be addressed - lastResource is not the newest call. Gong returns /v2/calls ordered by call id, not by started, so it's best to sort the batch by started descending before slicing.
I've also made a couple of other fixes and QA'd the changes. Thank you once again.

- Line 100: Update both the main and unfilterable call sorting logic to compare
Gong IDs numerically rather than via String.localeCompare, preserving
lowest-ID-first ordering before the DEFAULT_MAX cap is applied. Use the existing
sort paths near the unfilterable and filtered collection handling, and retain
correct behavior for numeric IDs of different lengths.
- Around line 186-191: Update processResources to await all processEvent

unseenResources.forEach(this.processEvent) flow with an awaited aggregation that
rejects on any failed emission. Only call setLastCreatedAt and persist

failures.

Included review availability: Your plan provides up to 10 included reviews per hour; 9 remain after this review.
`common/constants.mjs` reaches every action in this app through `gong.app.mjs`, so changing it obliges a version bump on five components this PR does not affect. Keep the db key local to the polling source instead, alongside the lookback constants that are there for the same reason.
…rsisting Gong call ids are numeric strings past Number's safe integer range, so `localeCompare` ordered different-length ids incorrectly and the ledger's cap could evict the wrong entries. `$emit` is async, and the emit loop neither returned nor awaited its promises, so state was persisted once the events were queued rather than once they were out - a failed emission would still have advanced the cursor. The loop is awaited now, and `run`/`deploy` await the batch so a failure fails the poll instead of escaping as an unhandled rejection.
Summary
Closes #21479.
New Callstores the neweststartedit has seen and sends it back asfromDateTime. Gong applies that filter tostartedserver-side, but it only makes a call queryable once it has finished processing it — and those two times are not the same. A call whose processing finishes after a later-starting call has already moved the cursor past it is never returned again by any poll, silently and permanently.The cursor is now held behind the present:
so a call that becomes queryable within that window is still inside the next poll's range. The calls this reads a second time are dropped by
dedupe: "unique", which the source already sets.Two details worth calling out:
paginatestops atDEFAULT_MAX(600) resources per poll. Without the floor, an account recording more than 600 calls per lookback window would have its cursor land back inside a range it had already read, and it would stop advancing entirely. Clamping against the stored value keeps every poll moving forward, because the newest call read is always at or after the cursor that requested it.startedleaves the cursor alone rather than writingInvalid Dateinto it. The old code stored the raw string, so this path could not throw before; now that the value is parsed, it can.The constant lives in
sources/common/polling.mjsrather thancommon/constants.mjson purpose: the latter is imported by all six components in this app, so putting it there would force a version bump on five components that this change does not affect.Sizing the window
The window has to span a whole call plus the processing that follows it, not just the processing — because Gong filters on the time a call started while processing only begins when it ends. An hour-long call whose processing takes half an hour surfaces 90 minutes after the timestamp the filter is applied to.
Gong's processing is generally quoted at 10–60 minutes after a call ends, so the default is two hours: an hour-long call plus an hour of processing. That is a defensible default rather than a universal bound, and no bound is derivable from the component's side — the safe number depends on how long a given workspace's calls run and how quickly its recordings are processed.
So the window is a prop,
Processing Lookback (Hours), defaulting to 2. A workspace that still misses calls can widen it without waiting on a release; one recording more calls than a single poll can read within the window can narrow it. I would rather expose the number honestly than bury a guess in a constant — but if you would prefer it fixed, or prefer a different default, say which and I will change it.Checklist

How I verified
I replayed the reporter's scenario against the real source module — importing
sources/new-call/new-call.mjsitself, with a fakedb, a frozen clock and a stub Gong that filters onstartedserver-side and only returns a call once its processing time has passed.On
master:With this change:
Poll 4 shows the cursor catching up to the newest call once more than the window has passed, so the range does not grow without bound.
Limitations of that harness, stated plainly: it is a simulation of Gong's filtering behaviour read off the API documentation and this component's own code, not a run against a live workspace, and it does not implement
dedupe: "unique"— the repeat emissions it prints are what the platform's dedupe is expected to drop. I also could not runeslint, since installing the monorepo's dependencies was not practical here;node --checkpasses on the modified file and I kept to the surrounding style.Summary by CodeRabbit
