PR 7 of the #1169 train. One thesis: every paid or destructive action shows its price before the click, and no payment flow dead-ends.

What changed

1. Trial requests name their price (UX-1)

trialPriceInPaise is a real column, the fetcher already includes it, and the #780 result extension already turns it into a number in paise before it crosses the RSC boundary — it was simply never declared on the client type, so it was never rendered. The booking modal and the CTA now show either "Free trial" or the formatted amount, and a paid trial adds the copy that says nothing is charged now and a payment link follows the consultant's acceptance.

Formatted with formatCurrencyAmount(paise, plan.priceCurrency), deliberately not useCurrency().formatPrice — the latter assumes INR paise and applies the viewer's FX rate, which would relabel a plan already denominated in another currency.

2. Removing an attendee confirms, and reports the money (UX-3)

One click, no confirmation, and the DELETE response — a refund summary since #1003 — was explicitly discarded in a comment. Now: a confirm dialog that states the organiser tier (full refund at any notice), a success toast carrying the actual outcome from the response, and a destructive toast with a ToastAction retry on failure. The bare <div>Error loading event data</div> became a card with a retry.

The toast distinguishes three genuinely different facts the old code could not: never removed, removed with no payment found, and removed with a policy-zero refund.

3. Cancel preview (UX-4)

New read-only GET /api/appointments/[appointmentId]/cancel/preview. It computes what cancelling right now would return, without writing anything, by reusing the POST route's own pieces rather than restating the rule:

  • resolveBookingRefundContext from lib/booking/cancellation-scope (a pure read; its only side effect is a fire-and-forget system-error record on an unreachable branch)
  • computeRefundPct + parsePolicySnapshot from lib/payments/operations/cancellation-policy
  • the linear per-session proration base (floor(gross × remaining / total)), mirroring the math on fix/reschedule-cancel-lifecycle
  • the same clamp to refundablePaise
  • Number.POSITIVE_INFINITY for the never-scheduled case, and 100% for group events, which cancel wholesale through refundWholeEventPayments

Returns { refundPct, estimatedRefundPaise, currency, hoursUntilNextSession, prorated, creditFunded }. Authorization mirrors the POST route exactly — participant, privileged, or org OWNER/MAINTAINER — because a preview that answers where the cancel would 403 is a quote for an action the viewer cannot take.

CancelConfirmationDialog fetches it on open and renders the concrete number, with a loading state and the old policy sentence as the fallback on any error.

4. Razorpay: no dead ends, and success parity (UX-5)

  • modal.ondismiss. Closing the gateway sheet fires neither handler nor payment.failed, so the button sat on "Processing..." forever with no way back. It now resets and says the payment was not completed and can be retried. The blanket finally { setIsProcessing(false) } also un-disabled the button while the sheet was open; processing state is now owned by the sheet's own exits.
  • Success routes to /checkout/checkout-success. Razorpay landed on /dashboard, where the webhook-driven confirmation gap reads as "I paid and got nothing". Stripe has always gone to the poll surface that drives the pipeline synchronously and says "payment received, confirming". Payment.paymentIntent is the Razorpay order id, which is what the verify route keys on, so that is what gets handed over.

5. Webinar re-entry honesty

The page printed the plan's maxParticipants, which an instance override silently contradicts, and counted nobody. It now uses getWebinarCapacity from lib/events/capacity, shows real remaining seats (or "Sold out"), disables both pay buttons and re-checks at submit. fetchWebinarPlanDetail already included slotsOfAppointment.user — the page's type just never said so, which is exactly how countWebinarParticipants silently answers 0. Also: the date/time block now describes the instance named by ?eventId rather than the plan's first webinar.

6. Trial checkout page: correct times, and linked

  • toLocaleString("en-IN") with no timeZone in a server component resolves against the server's zone (UTC on Netlify). Both datetimes — the session and the payment deadline — now render viewer-local via a small client component.
  • The page is no longer orphaned. The pending-payments widget and the appointment sheet's "Pay now" point at it wherever the trial id is available (payment.id is the TrialSession id in the widget; the sheet's vm id is trial-<id>).

7. Subscription/class reschedule clamps

buildRescheduleSubject omitted allowedStart/allowedEnd/schedulingTimezone/sessionsPerWeek/totalSessions, so the grid was unclamped and the consultee's choice was rejected at submit instead of being unselectable with a stated reason. Populated the way the allocate subject does. Class gets the same treatment — it is the other recurring shape.

8. P2 riders

  • The "slot starting soon" destructive toast re-fired every 60 seconds for as long as the tab stayed open. Fires once per threshold crossing.
  • PendingPaymentsWidget returned null while loading (collapsing the sidebar column, then pushing everything back down); it now renders a widget-shaped skeleton. And it passed payment.amount to formatPrice, which assumes INR paise and converts — so a non-INR row was converted a second time and relabelled. Non-INR rows now format in their own currency.

9. Price-parity suite (#1167)

__tests__/payments/checkout-price-parity.test.ts — 35 tests over base / discounted (percentage, capped percentage, fixed, over-value fixed) / credit-applied / international fixtures, asserting page math against the server derivation within one paise (the two round differently by construction: the client keeps two decimals of a paise value, the server rounds to whole paise).

Residual, stated honestly. The server's amount derivation lives inside createCheckoutSession's Prisma transaction (checkout.ts ~470–538) and is not exported, so it cannot be imported without standing up prisma, razorpay and stripe. The suite imports every pure primitive that derivation uses — the real determineTax and the real MIN_CREDIT_REDEMPTION_PAISE — and transcribes only the sequencing, once, in a commented helper. Extracting that derivation into a pure function is the proper fix and is not in this PR's scope.

The suite also records a live divergence rather than papering over it: the ₹500 credit-redemption floor is enforced only on the server, so on an order below it the pages show a credit the charge will not honour. Asserted as a named failing-behaviour test so the eventual fix turns it red instead of passing silently.

Descopes and contradictions

  • ConsulteeAppointmentsAdapter.tsx does not pass appointmentId to the cancel dialog. It is on this PR's do-not-touch list, and it is the main consultee cancel surface. The prop is optional and the dialog degrades to today's copy without it, so the one-line follow-up is appointmentId={activeVm.appointmentId} at ConsulteeAppointmentsAdapter.tsx:435. Wired on the consultant adapter, which is not restricted. This is the gap worth closing first.
  • The appointment-row "Pay now" still opens the gateway link for trials. Same file, same reason. The sheet's "Pay now" (AppointmentSheet.tsx) does route to the branded page.
  • lib/booking/org-actor.ts is replicated from origin/fix/reschedule-cancel-lifecycle (fix(booking): the reschedule loop closes; lifecycle authz, proration, and audit stop lying #1174), byte-identical so the merge resolves trivially. The TODO(#1174) lives in the preview route, where it cannot conflict.
  • Trials get a 403 from the preview route, because the POST cancel route has no trial branch in its participant check either. Mirroring it was deliberate; the dialog falls back to today's copy. Fixing the cancel route's trial authorization is a separate change on a do-not-touch file.
  • getWebinarCapacity reads a response cached s-maxage=60, so the seat count can be up to a minute stale. The server holds the real gate under the allocation lock; this is a display plus a soft gate, not the authority.
  • Removed an unnecessary resolvedSearchParams dep from the webinar page's handleCheckout — it was already unused there, and the rule's "missing deps" message had been masking it.
  • Refund amounts in the attendee-removal toast are formatted as INR, because refundRemovedAttendeeSeat returns no currency and lib/payments/operations/** is do-not-touch. Settlement is INR-only by design, so this is correct today.
  • Prettier: the repo is not prettier-clean at dev (several files I touched already failed format:check before my changes), so I did not reformat them and create unrelated diff noise. All four new files are prettier-clean.

Verification

  • NODE_OPTIONS=--max-old-space-size=8192 npx tsc --noEmit --incremental false → exit 0
  • eslint on all 17 touched files → exit 0, zero warnings (the repo-wide pre-existing warnings are all in files this PR does not touch)
  • Full jest suite: 248 suites, 2816 tests, all passing
  • No prisma generate, no next build, no DB access

Closes #1167. Part of #1169.

Recurring slot-picker metadata

Layer / File(s) Summary
Recurring scheduling subject data
lib/scheduling/slot-picker-subject.ts
Subscription and class subjects now forward scheduling bounds, timezone, cadence, and session limits.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 338c4

The PR improves price and cancellation transparency, but the current version can still let buyers start payment for sold-out webinars, show an amount that differs from the eventual charge, display an incorrect group-cancellation refund, or falsely report that an attendee removal and refund did not happen. These user-facing payment and cancellation risks should be fixed before merge.

… amount floor (#1161)

resolveBookingRefundContext filtered payments to amount > 0, so a fully-
credit-funded payment never became paidPayment and the cancel route's
isFreeCreditFunded branch could not fire — dead on arrival. Caught by the
#1180 preview work, which had to do its own lookup to see the free_ rail.
The floor is gone; zero-amount rows flow through the tier math harmlessly

The #1169 train's wave-1 PRs carried their own documentation; the late
ones (#1174, #1177, #1178, #1179, #1180) shipped without changelog rows.
Adds 21 rows to the August 2026 table, each verified against the PR diff
rather than the PR description, plus a note in 01-architecture recording
that the client auto-allocator is gone and the grid now polls.

… and audit stop lying (#1174)

* fix(booking): the reschedule loop closes, and the lifecycle stops mislabeling actors and dead-ending refunds (#1169 PR 4a)

The counterparty can finally answer a proposal (#1163): a respond endpoint
accepts (proposed times re-validated through the full allocator under the
wide lock, finalized ACCEPTED via CAS) or declines (guarded transition;
released slots deliberately stay in the allocate queue — the withdraw
module documents that rule). The consultee's event reads carry the live
proposal with its proposed times, ending the indefinite "Awaiting schedule
confirmation". Anti-oracle 404s match the withdraw route.

Admins of the funding org may cancel and reschedule org-funded bookings
(#1166 ORG-9 lifecycle half), acting on the PAYER side: cancellations tier
like the buyer's own, and their reschedule proposals carry the consultee
role. Subscription cancellation gains linear per-session proration — the
undelivered share of the plan price tiered by the policy — replacing the
₹0 + MANUAL_REVIEW escalation (#1006). Credit-funded bookings route to the
restoration rail on cancel (#1161): full restoration in full-refund
windows, a recorded escalation for partial windows where no product rule
exists yet. The cancel activity log gains its missing "system" arm, removed
attendees lose event-channel access at refund time, and the booked
notification carries the session time (#1085 in-repo residue).

The consultee-facing UI for the response loop rides PR 4b.

Closes #1006. Part of #1169, #1163, #1166, #1161, #1085.

* fix: address review round 1 on #1174

CI was red on __tests__/payments/cancel-route-refund.test.ts — the one suite
the PR's verification missed, because it lives under __tests__/payments/ and
the run covered __tests__/booking-algorithm/.

- `escalates a partly-consumed plan instead of guessing a proration` pinned the
  ₹0 + MANUAL_REVIEW behaviour that this PR deliberately retires: linear
  proration (#1006, item 3 of the PR) replaced it, and the sibling
  reschedule-respond suite already asserts the escalation string is gone.
  Rewritten to pin the shipped rule instead — 1 of 3 sessions delivered, next
  session 72h out, so the 100% tier applies to floor(500000 × 2/3) = 333333
  paise and nothing lands on the ops queue. No production code was changed to
  make it pass.
- The #1006 comment above the refund branch survived the change and now
  described an escalation that is no longer there, sitting over the
  `isFreeCreditFunded` test it does not describe. Rewritten to say why the
  credit branch runs first.

Verified: 1035 tests green across __tests__/payments/ and
__tests__/booking-algorithm/, tsc clean on a cold cache, eslint clean.

Part of #1169.

* fix(booking): address review round 1 on #1174

- Proration measured the undelivered share against a plan that had shrunk.
  The denominator summed only COMPLETED + live slots, so every session that
  was terminal-but-not-completed dropped out of it: three UNVERIFIED past
  sessions plus seven live ones scored 7/7 and refunded the whole price for a
  plan that was 30% consumed. `slotsTotal` is the plan the buyer bought.
  slotsTotal === 0 still keeps the full gross — that is the never-scheduled
  plan `neverScheduled` already tiers at 100%, not a zero base.
- Credit restoration reports what came back instead of a hardcoded 0, which
  reintroduced the ambiguity the field exists to remove.
- Accepting a proposal now refuses a booking with a live payment dispute, as
  cancel and reschedule already do. Placed AFTER the counterparty gate so the
  guard cannot be walked as a dispute oracle; decline stays open because it
  moves nothing.
- acceptProposal honours expiresAt. The expiry job runs hourly, and expiry is
  min(now + 72h, earliest released session - 24h), so accepting a lapsed
  proposal was how a booking landed inside the 24-hour window the reschedule
  route refuses to move it into.
- The org-admin membership lookup left the interactive transaction: it runs on
  the global client, so it was taking a second pooled connection while the
  transaction held its own -- the shape #908 documents.
- The consultee read now loads the live proposal for SUBSCRIPTION appointments
  (it was on consultation and webinar only, and webinars never carry one). The
  three copies collapse into one shared select.
- The respond route reads each booking relation instead of casting the union,
  so a changed select shape can no longer silently drop the consultant from the
  authorization set; the two nested ternaries SonarCloud flagged are gone.
- reschedule-respond.test.ts was source-text assertions that proved nothing.
  Replaced with 24 behavioral tests driving the real helpers and route against
  a mocked Prisma and allocator, plus 6 new behavioral cancel-route tests
  (proration denominator, credit restoration, org-admin payer-side authz).

Part of #1174, #1169, #1163, #1166, #1006, #1161, #1008.

* docs(booking): record the two accept-path refusals the review round added

The response-loop section described accept as unconditional once the caller is
the counterparty. It now also states the expiry refusal (and why the status
alone cannot stand in for the deadline), the dispute freeze, why the freeze
sits after the authorization gate rather than before it, and why decline is
exempt from both.

Part of #1174, #1163, #1008.

Inline comments:
In `@__tests__/payments/checkout-price-parity.test.ts`:
- Around line 46-76: Extract the amount derivation currently represented by
serverAmount into a pure exported function in the checkout implementation,
preserving discount, tax, and credit sequencing. Update createCheckoutSession to
call this shared function, and replace the local serverAmount transcription in
the parity suite with the exported function.
- Around line 250-271: Update the client pricing path used by clientAmount to
enforce MIN_CREDIT_REDEMPTION_PAISE, or reuse a server-authoritative quote, so
below-floor orders do not redeem credits. Then revise the DIVERGES test to
assert server and client credit and total amounts are equal for this case.

In `@app/api/appointments/`[appointmentId]/cancel/preview/route.ts:
- Around line 34-255: Refactor the GET handler into focused named helpers for
appointment authorization and refund estimation, reducing its cognitive
complexity below the configured limit of 15. Keep authentication, lookup,
authorization outcomes, refund calculations, error handling, and the existing
response contract unchanged; use the current GET flow and symbols such as
resolveBookingRefundContext, computeRefundPct, and bookingPayment as the helper
boundaries.
- Around line 179-182: Update the group-event preview path around
resolveBookingRefundContext so consultant-initiated cancellations use the same
aggregate payment set as refundWholeEventPayments, while attendee self-service
previews remain scoped to the attendee payer. Preserve the existing
authorization and individual-booking behavior.

In `@app/checkout/plans/trial/`[trialId]/page.tsx:
- Around line 115-118: Update the trial payment display around
formatCurrencyAmount to read the persisted amount and currency from the Payment
record created by createApprovalPaymentIntent, using its existing link to the
trial appointment or adding a direct TrialSession association. Ensure the page
and pending-payments API use this Payment data instead of the mutable
trial.subscriptionPlan values.

In `@app/checkout/plans/trial/`[trialId]/ViewerLocalTime.tsx:
- Around line 36-39: Update the fallback rendering in ViewerLocalTime so it
preserves timezone information instead of truncating and replacing the ISO
timezone marker. Render the full value or explicitly append UTC, while leaving
the formatted effect result unchanged.

In `@app/checkout/plans/webinar/`[planId]/page.tsx:
- Around line 267-280: Move the fresh capacity validation out of handleCheckout
and into the shared production payment-initiation path used by the Razorpay and
Stripe components, or run it immediately before either gateway starts. When the
response is full, update isSoldOut so both production controls disable and
prevent payment initiation; preserve the existing rejection behavior.

In
`@app/dashboard/consultant/`[consultantId]/(features)/appointments/participants/[eventType]/[eventId]/page.tsx:
- Around line 159-179: Update the removeParticipantMutation onError handler to
invalidate or refresh the participant roster, and replace the toast description
with wording that only states the removal and refund result could not be
confirmed. Do not claim that nothing changed or that no refund was issued, and
preserve the existing retry action and error reporting.

In `@components/appointments/consultee/CancelConfirmationDialog.tsx`:
- Around line 133-139: Update the refund display in CancelConfirmationDialog so

Test the production server amount derivation.

serverAmount() is a local transcription. It does not call the calculation in createCheckoutSession. If lib/payments/operations/checkout.ts changes its sequencing, this suite can still pass while the gateway order amount changes.

Extract the server amount calculation into a pure exported function. Use that function in both checkout creation and this parity suite.

Do not make the known credit-floor mismatch pass.

Lines 258-270 assert that the page applies ₹200 credit while the server applies none. The buyer can see a lower total than the amount the server charges.

Apply MIN_CREDIT_REDEMPTION_PAISE in the client pricing path, or display a server-authoritative quote. Then change this test to require parity for below-floor orders.

Six places where the platform took a decision from someone by not telling
them what it cost, plus the two dead ends that followed a payment.

Trial requests named no number anywhere — `trialPriceInPaise` was on the
plan and in the payload, but absent from the client type, so a paid trial
read as free until the payment link arrived. The modal and the CTA now
name the amount, in the plan's own currency, and say when it is charged.

Removing an attendee was one click, silent, and issued a refund whose
summary the client explicitly discarded. It now confirms, states the
organiser tier, and reports what actually came back; failures get a toast
with a retry instead of a console line.

Cancelling said "any refund follows the booking's cancellation policy",
which is true and useless — the number is knowable before the click. A new
read-only preview route computes it from the cancel route's own pieces
(same context builder, same tier function, same proration, same clamp) and
the dialog renders it.

Razorpay: closing the gateway sheet left the button on "Processing..."
forever, and success landed on /dashboard, where the webhook gap reads as
"I paid and got nothing". Both fixed — dismiss resets and explains, success
goes to the same /checkout/checkout-success poll surface Stripe uses.

Webinar checkout printed the PLAN's capacity, ignoring the instance
override, and counted nobody, so a sold-out event advertised its full
capacity and took the money. It now shows real remaining seats and refuses
to sell when full.

Also: viewer-local times on the trial checkout page (it was formatting in
the server's zone) and that page linked from the surfaces holding a trial
id; the subscription/class reschedule grid clamped to the period the buyer
actually bought; a destructive toast that re-fired every 60s fires once;
the pending-payments widget keeps its shape while loading and stops
double-converting non-INR amounts.

Closes #1167. Part of #1169.

… charge does

The preview prorated a subscription refund over `sessionsCompleted +
sessionsRemaining`. #1174 landed the authoritative formula on the POST
route and it divides by `slotsTotal` — every session the plan ever held
time for — precisely because the completed+live sum drops terminal-but-
not-COMPLETED sessions out of the plan and measures the undelivered share
against a plan that has shrunk.

So the two disagreed on exactly the bookings the split exists for. A
ten-session plan with three UNVERIFIED past sessions, two COMPLETED and
five live quoted 5/7 of the price and paid 5/10. A plan whose sessions
were all cancelled quoted the whole price and paid nothing: with no
completed and no live sessions the old gate read "not proratable" and
fell through to the full gross.

`prorated` moves onto the same two numbers for the same reason — a
session that is no longer live has already shrunk the quote whether or
not it COMPLETED, and the flag is what tells the buyer the number was
prorated at all.

Part of #1169, #1167.

…edit payers

Two money statements the dialog made that the POST route does not keep.

Group events. Cancelling a class or webinar never reaches the notice tiers:
the POST route hands the whole event to `refundWholeEventPayments`, which
refunds EVERY attendee's seat in full, whoever pressed cancel. The preview
quoted that act against the VIEWER's own payment — and an organiser owns no
seat, so it found nothing and rendered "No refund at this notice" over a click
that was about to return the entire roster's money. The preview now returns an
aggregate for group events: the sum of the attendees' refundable balances, read
through `refundWholeEventPayments`' own payment filter, plus the paid-seat count
and a `wholeEvent` flag. The dialog names both — "refunds all N attendees in
full, ~X in total" — and says so plainly when nobody has paid yet.

Credit-funded bookings. #1161 made credit restoration all-or-nothing: a
full-refund window restores, and anything below it records MANUAL_REVIEW and
restores nothing pending the product call. The dialog promised restoration for
both. It now promises it only at 100% and, below that, says the credits are
reviewed manually rather than returned — no invented policy, just the branch the
money path actually takes.

The route stays strictly read-only. Its estimation and authorization paths are
extracted into named helpers, which is what drops the handler under SonarCloud's
cognitive-complexity limit, and the notice-hours ternary is now its own
statement. The approximation marker moved inside the amount so `~` and the
figure cannot be split across elements.

…laims match their facts

Review follow-ups, all of them the same shape as the PR: a surface stating
something the system does not do.

The webinar seat re-check was inert where it mattered. It lived inside
`handleCheckout`, whose only production caller is the development mock-pay
button — the real Razorpay and Stripe controls take `checkoutData` and open the
gateway themselves, so a webinar that filled while the tab sat open still let
the buyer pay into a rejection. Both gateway components gained an optional
`onBeforeCheckout` guard that runs on the click, before the spinner, and aborts
when it returns false; the webinar page uses it to refetch the plan `no-store`
(the endpoint is cached `s-maxage=60`, which is the staleness being corrected),
refresh `isSoldOut` so both buttons disable behind it, and stop the payment. A
failed check does not block the sale: the allocation lock on the server is the
authority, and refusing a paying customer over a timed-out display query trades
a real sale for a race we do not own.

The trial checkout page quoted the plan, not the charge. `createApprovalPaymentIntent`
freezes the amount and currency onto the Payment row when the consultant accepts
and mints the pay-link for exactly that figure, while `trialPriceInPaise` stays
editable underneath — so a consultant who repriced after accepting turned the
page into a number the gateway would not honour. It now reads the persisted
payment, falling back to the plan only before one exists, where the plan price
genuinely is the quote.

The attendee-removal error toast asserted "nothing was changed and no refund was
issued". A lost response is not a lost write: the DELETE may have disconnected
the attendee and issued their refund before the connection dropped, and a retry
answering `removed: false` would not recover the original result either. It now
refreshes the roster and says only that the outcome could not be confirmed.

And the pre-hydration timestamp keeps its UTC marker. Trimming the ISO string to
a bare wall-clock dropped the one character saying which zone it was in, so a
payment deadline read as local time and was wrong by the viewer's offset.

* docs(collaborators): rewrite all seven files against the merged Collaborator model

The collaborators folder was the worst-drift band in the repo: it still
documented the deleted WebinarCollaborator/ClassCollaborator models and
their per-type role enums (merged into one Collaborator model by #784),
a permissions JSON override (replaced by four typed booleans in #768, of
which only canSeeAttendees is enforced today), a nonexistent
lib/collaborators/permissions.ts module and checkWebinarPermission
function, and a float revenueSharePercentage column (revenueShareBps Int
since #772 B5). All seven files are rewritten from the current code:
service.ts, availability.ts (the AE-2 enforced co-host guard), the
collaboration routes, and the settlement path in earnings-service.ts
(pool-based split with floors per #778 §C-2, org settlement per #773,
verified Stream revocation per #1125).

FundingSource at :1100 (said 901), and the fundingSource resolution at
checkout.ts:1986 (said 1907). The remaining refs in the doc had drifted
the same way (PaymentLeg, WalletTopUp, skipPayment, walletDebit, and the
refund.ts audit/clawback/Step-9 blocks); each new number was verified
against the current files before writing. Also cross-links the new
booking-side page for this rail.

DPDP consent, fundingSource from the org BillingAccount, INVOICE
credit-limit and verified-domain gates, ProgramAssignment resolution —

wallet debit; CLASS debiting N engagements at checkout while
SUBSCRIPTION debits lazily per allocation; and inline settlement with

* docs(prompts): index the corpus, fix the ledger drift, reconcile the seed cohorts, add two booking cases

Four changes to the prompts corpus. (1) A new prompts/README.md indexes
the 43 prompt files by directory and states how the enterprise-tests
tree relates to docs/enterprise/90-audits/03-verification-guide.md.
(2) shared-setup.md stops teaching the deleted three-ledger models:
FundingLedgerEntry and SettlementLedgerEntry (and WalletEntry) were
replaced by the LedgerAccount/LedgerTransaction/LedgerEntry double-entry
journal plus UsageLedgerEntry in #772 — rule 2, the glossary section,
the webhook-idempotency note and the schema table are all corrected.
(3) The two documented seed cohorts are reconciled: the founder@*.test /
TestPassword123! roster in shared-setup §2 never existed in the seeds
(and its table swapped the IIT/LearnPro shapes); the verification
guide's SeedPass123! roster matches prisma/seedFiles/, so §2 now defers
to it and each doc points at the other. (4) Two new case files in the
Agent-005 template style: 007 covers the reschedule-proposal response
loop (lands with train PR 3, #1162) and 008 covers maintenance-freeze
correctness — a freeze must not destroy a PENDING payment, and
freeze-then-cancel must not double-refund (lands with train PR 4,
#1163); both carry explicit coverage markers. New files are added with
-f, matching how the ignored-but-tracked corpus is versioned.

* docs: adversarial-review corrections — merged-reality alignment

Four corrections against merged dev, each verified before writing.

Rule 4 of the booking-doctrine skill listed `trial-slot-booking:` as a
live lock namespace. #1170 retired it entirely: trials now take the
shared `slot-booking:` atom keys, one key per 30-minute atom the booked
interval covers, floored to the half-hour grid. The rule also still
promised the consolidation as future work; it has landed.

`08-cancellation-flow.md` was untouched by this train despite the PR
claiming `Closes #1013`, and PRs 4 and 6 never picked it up either — the
file is byte-identical on dev. It still taught delete-on-cancel, no
authentication and no refunds, which are the three claims #1013 was
raised against. The walkthrough, every diagram, the record tables and
the error contract now match `cancel/route.ts`. The #1006 escalation for
partly-consumed subscriptions is gone: #1006 is closed and the linear
per-session proration replaced it, so the refundable base is
`floor(gross × sessionsRemaining / slotsTotal)` for subscriptions and
the policy tier applies to that base. The only surviving `MANUAL_REVIEW`
path is the credit-funded partial-window case (#1161).

The collaborators rewrite dropped a qualifier the pre-PR text had right:
`assertCollaboratorsAvailable()` is called from the webinar plan route
alone, so class-plan co-hosts have no availability guard. The over-claim
had spread to six files, all corrected.

`16-recurring-events-journey.md` still named the deleted
`ClassCollaborator` model; de-drifted to `Collaborator` with
`collaboratorType: CLASS` and `revenueShareBps` (#784, #772 B5).

The ~27 stale citations in `17-org-funded-checkout.md` and
`payments/05-b2c-b2b-funding-seam.md` are deliberately left alone —
they re-derive after this branch's final rebase.

Part of #1169. Closes #1013.

…s quote frozen amounts (#1181, #1182) (#1217)

* fix(payments): approval payments carry their appointment; duplicate guard goes live and reuses the pending link (#1181)

createApprovalPaymentIntent was invoked without appointmentId for
consultations and subscriptions even though both already own an
appointment at mint time — consultations create it when the request is
submitted, subscriptions carry the placeholder direct checkout made for
exactly this linkage. The Payment row therefore shipped with
appointmentId null, and four things were inert or dangerous because of
it:

checkExistingPayment walks appointment.payment, so it never matched an
approval payment — every retry minted a parallel gateway order, with the
distributed lock as the only line of defense. checkConsultationPayment
and the PaidWithoutAppointmentError 409 shipped by #1172 were unreachable
the same way. The capture webhook branches on payment.appointmentId, so
an approval capture fell into the legacy-create path and built a TWIN
Appointment for a one-to-one Consultation — colliding on the unique or
stranding the request-time appointment with its tentative slots. And a
mint that failed after the gateway call left a PENDING payment no retry
could find, the #1172 deadlock shape.

Both approval routes now thread the request-time appointment through
CreateApprovalPaymentParams (subscriptions pick the first under the
route's deterministic createdAt/id order), mirroring how direct checkout
anchors its Payments. The guard became findExistingLivePayment and grew
a reuse path: a PENDING payment from a prior attempt is handed back
as-is — Razorpay's client_secret IS the stored intent, so the original
pay-link reconstructs without a second gateway order — while SUCCEEDED
still refuses and EXPIRED falls through to a fresh mint. Capture now
confirms the request-time appointment instead of fabricating one.

The lifecycle doc's claim that approval payments are invisible to the
guard was true when written and false after this change; it now states
the reuse behavior instead.

Closes #1181. Part of #1169.

* fix(dashboard): pending-payments quotes the frozen Payment.amount, not the mutable plan price (#1182)

The consultee pending-payments surface read the plan's CURRENT price for
approval-pending consultations and subscriptions (and the plan's current
trialPriceInPaise for trials), while the pay-link it links to charges the
amount createApprovalPaymentIntent froze onto the Payment row at mint
time. A consultant who repriced after accepting turned the widget into a
number the gateway would not honour.

Same rule #1180 landed on the trial checkout page: quote the frozen
Payment first — earliest live payment on the appointment, or the trial's
own direct Payment — and fall back to the plan only before any payment
exists, where the plan price genuinely is the quote. The subscription arm
now orders its take-1 appointment pick like the mint does (#1181) so the
frozen charge comes off the appointment the pay-link actually anchored to.

Closes #1182. Part of #1169's residuals.

* fix(approval-payments): live-status filter on trial reuse; operative frozen quote; personal-appointment pin

CodeRabbit triage (all three Major findings verified against source):
- findExistingLivePayment's trial arm returned TrialSession.payment
  unfiltered — an EXPIRED order would have been handed back as a reusable
  checkout link instead of minting fresh. Now filtered to SUCCEEDED|PENDING
  like the other arms (+2 tests).
- pending-payments quotes the NEWEST non-deleted payment per appointment:
  a re-mint freezes the current quote onto a newer row, so newest is the
  operative charge an expired-order retry would resume.
- subscription arm pins its take:1 appointment pick to organizationId null,
  so a mixed subscription can't leak an org-funded frozen amount onto the
  personal dashboard.
