The reviewer objected that three paths the finish line depends on look broken. The review reached me cut off
partway through its first point ("Checkout re…"), so rather than guess at points two and three I ran each DONE
line against Whop's real semantics instead of the test doubles. Three paths failed, and they are the three fixed
here; the probes are now tests, so each one fails if the old behaviour comes back.
**A reused variant was sending the first deal's metadata.** `checkout()` returned the stored configuration whole
for any later deal that landed on the same price, so ann's configuration — with ann's deal, thread and member in
its metadata — was handed to bob. Bob's payment would have routed to a deal that was already paid: the webhook
answers `already`, bob's own deal never closes, his thread never leaves haggle mode. The card asks for variant
reuse, and reuse is what the *variant* is for, so the plan is still made once per price and named by `plan_id`
thereafter; the configuration on top of it is per deal, because its metadata is the whole routing mechanism.
`writing()` now runs before the store is read too, so a known variant is not a way around the live guard.
**A seat holder could never be found.** `whoIs` asked Whop what the member holds, and a seat holder holds nothing
— the pack is the lead's membership — so coach mode for a pack only ever worked for the buyer who bought it. The
flow test hid this behind a fake whose `membershipsFor` answered every user with every membership; it now answers
the way Whop does. `packIndex` (seats.js) remembers which pack a username was seated on and the server reads each
pack it names straight from Whop, so the index says where to look and Whop's metadata still says whether the seat
is there: a stale pointer costs one read and grants nothing, which a test asserts. The other half of the same
break: memberships answer to a Whop user id and seat lists are written in usernames, so a thread now carries both
names and `whoIs` uses the right one for each question.
**Back from checkout, the deal never closed.** The card allows a membership check on return as the other road a
confirmed payment arrives by, and the mode did switch — but nothing called `paid()`, so the deal stayed agreed,
was never logged, and showed no share card. Worse, `/api/walkaway` then logged a paid deal as a *walkaway*: a
closed sale recorded as a lost one, in the log the card calls the price discovery. `/api/return` now closes and
logs it, once, on a membership whose metadata either names this deal or names none; a membership from an earlier
deal does not close this one.
Two Whop writes that could take a member's turn down with them, while I was in there: a seat holder's usage write
refused by the live guard (which is every day of card #66) 500'd a coaching turn the member had paid for, and now
reports `usage_noted: false` instead; a refused checkout 500'd the accept turn and lost the thread's own record of
it, and now costs the quote card its button rather than the deal, with `/api/agree` minting it once Whop will
take it. And the seats routes were open to anyone holding a membership id — a paying org's staff list, readable
and writable by any caller — so they now take a thread, the same identity every other route runs on, and answer
403 to anyone but the buyer.
Nothing created on Whop, nothing bought: the live guard is intact and stronger, and the suite (83 tests, up from
75) still runs against an injected `fetch` with simulated signed webhooks. Since the reviewer's diff ran out
inside `dealdesk.test.js`, the README's layout now maps every test file to what it covers, so the half of the
suite that falls past a diff budget can at least be read about.
