…— recipient-zone dates, currency amounts, plan titles, labelled types, and a reschedule sentence that never reads "from to" (#536, #1085) The Novu templates live in the dashboard and interpolate payload fields verbatim, so whatever this repository puts in `dateTime`, `amount` or `appointmentType` is the exact text a customer reads. The inbox was showing raw ISO timestamps, integer counts of paise and shouted enum members. `lib/novu/humanize.ts` is now the single place that turns a stored value into the sentence fragment a template needs, and the conversion happens at the trigger boundary rather than at each call site: every `notifyX` accepts an input type holding raw values and sends the rendered shape. A template field without a unit suffix carries the human value; the machine value keeps the same stem under `dateTimeIso`, `amountPaise` or `appointmentTypeCode`. Dates render in the recipient's own `User.timezone`, so the multi-recipient helpers now group recipients by zone and send one payload per distinct zone instead of one payload that can be right for at most one reader.

…, the timezone race clears its timer, and a blank plan title falls back to the session label CodeRabbit round 1 on #1524. The five payload builders now lift each raw date field out of the input before spreading it, so a value the formatter refuses cannot survive under the display key that the templates gate on. The two-second recipient-timezone race clears its losing timer in `finally`. The capture webhook's plan-title chain now runs through `planTitleOrSessionLabel`, so an empty title falls back to the session label instead of a blank. The pin gains a zero-amount row (credit-covered checkouts are a live zero) and a garbage-date row.

CodeRabbit round 1 — triage (verified against

| # | File | Claim | Verdict | Action |
|---|---|---|---|---|
| 1 | lib/novu/service.ts (appointmentWire) |
A non-empty string the formatter rejects survives the ...input spread under the display key, and {{#if payload.dateTime}} treats it as truthy |
Legit. The spread came first; only a successful format overwrote it. Reachable only through a caller passing a malformed string (every live caller passes an ISO string or nothing), but the code contradicted its own comment | Fixed: all five builders destructure the raw date field(s) before spreading; rescheduledWire strips oldDateTime/newDateTime before handing the input to appointmentWire. Pin: a not-a-date reminder carries neither dateTime nor dateTimeIso |
| 2 | lib/novu/humanize.ts (resolveRecipientTimezones) |
The losing setTimeout of the Promise.race stays armed for up to 2 s after a fast read |
Legit. | Fixed: the handle is kept and cleared in finally |
| 3 | lib/payments/webhooks/handlers.ts:997 |
An empty-string plan title short-circuits the ?? chain, so planTitleOrSessionLabel never sees it and both payment notifications get a blank title |
Legit on the ?? semantics (an appointment carries exactly one plan family, so "first non-blank" and "trim inside the helper" are the same rule) |
Fixed: the chain is now the helper's argument, so the helper trims and falls back |
| 4 | __tests__/security/novu-payload-allowlist.test.ts |
Cover zero and negative money inputs | Half. Zero is a live amount (a booking paid entirely with referral credit still raises payment-success) and was unpinned. Negative has no source: payment_amounts_nonnegative (prisma/sql/check-constraints.sql:18) refuses it at the row, and the refund/dispute twins carry the same CHECK |
Added the zero row (amount: "0.00", amountFormatted: "₹0.00", amountPaise: 0); no negative row, because the constraint makes it unreachable rather than a formatting case |
Verification on the worktree: prettier + eslint clean on the four files; cold tsc --noEmit exit 0; 95 suites / 1021 tests across __tests__/security, __tests__/payments, __tests__/moderation, __tests__/booking-algorithm/reschedule. The four threads are resolved without replies per the triage convention; the @coderabbitai full review on a216dcd35 was rate-limited, so an incremental review is re-requested when the allowance returns.

Tip For best results, initiate chat on the files or code changes.
The fixes address the four findings:
The exclusion of negative formatting tests is appropriate because database constraints reject negative payment, refund, and dispute amounts before notification construction. ✏️ Learnings added

Learning: In this repository, `payment_amounts_nonnegative` in `prisma/sql/check-constraints.sql` rejects negative payment amounts. Equivalent constraints apply to refund and dispute amounts. Notification tests should cover zero-value payments when they are reachable, but negative-value payloads are unreachable from persisted payment records.

Summary
The Novu templates live in the Novu dashboard, not in this repository, and every one of them interpolates payload fields verbatim. Whatever this codebase puts in
dateTime,amountorappointmentTypeis therefore the exact text a customer reads. Three separate places had forgotten that, and the in-app inbox was showing raw ISO timestamps, integer counts of paise and shouted enum members.Reminder: Your consultation with Sarah Chen for Basic Consultation starts at 2026-09-06T02:23:35.600ZReminder: Your consultation with Sarah Chen for Basic Consultation starts at Sun, 6 Sep 2026 · 7:53 AM IST— and a recipient in New York readsSat, 5 Sep 2026 · 10:23 PM EDTfor the same instant.Sarah Chen rescheduled the CONSULTATION for Basic Consultation from toSarah Chen rescheduled the consultation for Basic Consultation from Sun, 6 Sep 2026 · 7:53 AM IST to a new time your consultant will confirmPayment of INR 5567948 received for cmqb1c4h900xxtxyohdnk96j7 (SUBSCRIPTION) with Aarav AndersonPayment of INR 55,679.48 received for Basic Consultation (subscription session) with Aarav Anderson— the plan id came from a defect already fixed by #1484/#1489; the paise and the enum are fixed here.consultee cancelled the CONSULTATION session for Basic Consultation. Reason:Aarav Anderson cancelled the consultation session for Basic Consultation. Reason: I am travelling that weekThe rule the payload layer now follows is that a template interpolates the unit-free field name and receives a value written for a person, while the machine-readable original travels beside it under the same stem with a unit suffix. So
dateTimecarries the sentence anddateTimeIsothe instant,appointmentTypecarriesconsultationandappointmentTypeCodecarriesCONSULTATION, andcancelledBycarries a person's name whilecancelledByRolecarries the discriminator.Money follows the same rule with one deliberate exception, driven by the live templates rather than by the money. Four in-app templates already print
{{payload.currency}} {{payload.amount}}themselves —payment-success,payment-failed,refund-processedandrefund-requested— and they cannot be edited on the Novu plan currently in use. A symbol-bearingamountwould render "INR ₹55,679.48" in exactly those four places, soPaymentSuccessPayload,PaymentFailedPayloadandRefundPayloadsendamountas the localised figure with the symbol stripped (55,679.48), leavecurrencyas the ISO code the template prints, and carry the symbol-bearing string beside it asamountFormattedfor whichever template is written next.amountPaiseremains on all of them. Every other money payload —PayoutPayload,DisputePayload, the referral payloads and the eleven organisation ones — keeps the symbol insideamount, because nothing prints a currency code next to it.The stripping is done by a new
formatCurrencyAmountBareinutils/formatting.ts, which drops the currency part from the existing currency formatter's own output rather than configuring a second formatter, so grouping, locale and subunit rules cannot drift between the two shapes.RefundPayloadis shared byrefund-failedas well as the two live refund templates, and it keeps one shape across all three: a payload type that meant different things depending on which workflow carried it would be a trap.Call sites do none of this themselves. Each
notifyXfunction now takes an input type (AppointmentPayloadInput,PaymentSuccessInput,RefundInput,OrgInvoiceIssuedInput, …) holding the values exactly as they are stored, and the trigger boundary inlib/novu/service.tsandlib/novu/org-workflows.tsrenders the customer-facing shape throughlib/novu/humanize.ts. That is why most of the forty-odd call sites are untouched by this change and yet all of them are fixed: a new call site cannot forget to format anything, because it never had the opportunity.The per-recipient timezone design
A date is only meaningful once you know whose clock it is on.
formatNotificationDateTimerenders in the recipient'sUser.timezone, falls back toAsia/Kolkatawhen that column is unset or holds a zone Intl cannot resolve, and always names the zone it used so nobody has to guess.That creates a problem for
triggerForMultiple, which sends one payload to a list of subscribers: a single rendered date can be correct for at most one of them. Every workflow whose payload carries a date now goes throughtriggerForMultipleZoned(andtriggerManyZonedon the organisation side) instead. It loads all recipients' zones in one query, groups the recipients by zone, and sends one payload per distinct zone. Both parties to a booking usually share a zone, so this is a single trigger in the common case and two in the cross-border one; the existing batching, deduplication and deterministictransactionIdare all preserved because the zoned helper delegates to the original.The zone lookup is deliberately defensive. It is bounded by a two-second race and swallows every error, falling back to the platform default for all recipients.
PG_POOL_MAX=1on Netlify means this read waits behind whatever else holds the single connection, and a caller triggering from inside a transaction would otherwise wait on a connection its own transaction is holding. Every date-bearing trigger site in the codebase was checked and all of them dispatch after their transaction commits, but the guard makes the failure mode "one notification renders in the default zone" rather than "the request hangs".Two payloads have no recipient whose zone could be used, and both say so in their field documentation: a maintenance broadcast goes to every subscriber at once, and an organisation invite is emailed to somebody who does not have an account yet. Both render in the platform default zone.
The reschedule sentence (#1085, code half)
AppointmentRescheduledInputkeeps the discriminated union #1083 introduced, so a caller still cannot construct aMOVEDorPROPOSEDoutcome without both timestamps. The wire payload now declaresnewDateTimeas required, and the trigger boundary fills it with a phrase when there is no instant to render — "a new time your consultant will confirm" for a release, "the time it was already booked for" for a declined or withdrawn proposal. The blank-blank sentence is now unrepresentable from either direction.The cancellation sentence
The live
appointment-cancelledtemplate reads "{{cancelledBy}} cancelled the {{appointmentType}} session for {{planTitle}}. Reason: {{reason}}", and it was failing at both ends.cancelledByopens the sentence, so it was starting with the lower-case word "consultee". One payload reaches both parties at once, which rules out a relative phrase — "Your consultant" is false for the consultant reading their own copy — so the field now names the person (consultantNameorconsulteeName, whichever acted), or reads "The platform" for a system-driven cancellation. Every branch is capitalised because of where it sits. The raw discriminator moved tocancelledByRolefor any template that wants to branch on who acted.reasoncloses the sentence, and it was optional, so a cancellation with no stated reason ended on a dangling colon. It is now required on the wire payload, resolved by a newcancellationReasonLabel: an exactCancellationReasonmember becomes a clause — the moderation paths were sending the bare enum memberMODERATIONto the person it had just been used against, and that now reads "a moderation decision on this account" — free text a user typed passes through verbatim, and nothing at all becomes "No reason given". The enum table is exhaustive overCancellationReason, so a reason added to the schema without copy fails the build rather than reaching an inbox as its own identifier.The specs in
03-novu-template-specs.mdwere corrected to the live copy for this workflow.Files

No template edit is needed for dates, plan titles, appointment-type labels, the cancelled-by noun or the four
{{currency}} {{amount}}templates — the last of those is handled on the wire, as described above, precisely because those templates cannot be edited today. Two items remain, and they are dashboard work rather than repository work.appointment-rescheduled— the template still renders "from X to Y" unconditionally. The sentence now always completes, so nothing is blank, but a release would read better as its own sentence. Branch on{{payload.outcome}}as Novu template still renders "from X to Y" for a reschedule with no new time — dashboard edit needed to finish #1083 #1085 describes.

These fields were named*Paisefrom the outset, so the integer they carry is honest and could not simply be replaced with a string; the formatted amount arrives as a new unit-free sibling (total,amount,expectedTotal,balance,minimum,newBalance). Any template printing{{payload.totalPaise}}or{{payload.amountPaise}}today is showing paise and should switch to the unit-free name. The organisation date fields need no edit.Also left alone deliberately:
AppointmentPayload.dateTimeis still absent from the twonotifyAppointmentCompletedcalls in the auto-complete sweep, which is the residual #1085 lists. Adding it means widening a select in a sweep this pull request does not otherwise touch, so it stays on #1085.Closes #536
