Closes OPE-440.

The bug

Every Steam base-app buyer receives a granted subscription month (subscription.provider === null). While that grant was live, they had no way to pay us at all:

  • the tier they held rendered "Subscribed" with no button — no request was ever made;
  • any other tier failed with "Couldn't update your subscription".

At launch that is the entire cohort, for their whole first month — the window where conversion is most likely.

The second symptom came from routing: a granted subscription fell through to changeSubscriptionTier, and the server answers 400 "Cannot change tier of a granted subscription". That refusal is correct and stays — change-tier reprices an existing provider subscription, and a grant has none. A granted player's tier selection is a first purchase.

The API already admitted this on both rails (infra OPE-228/OPE-294); the client simply never used the carve-out. Nothing server-side changes.

What changed

One definition of "granted"isGrantedSubscription in ApiSchemas.ts, now shared by the account panel and the store instead of each re-deriving it. It preserves the documented three-state rule for provider: null granted, a rail string paid, and undefined (a server predating the field) falling back to paid — the safe side at every caller, since it keeps Cancel in front of a paying subscriber and never sends one to a second checkout.

Routing — a granted subscriber reaches startPurchase for any tier, including the one they hold. No rail check: a grant has no provider, so the device decides, which is what paymentsProvider() already does.

The store tile — a granted tier is no longer marked "owned", so it renders a price button rather than a dead "Subscribed" label.

Honest copy. When a paid subscription settles, the server expires the granted row in the same transaction: the paid period starts immediately and remaining free days are forfeited outright — no credit, no extension, no proration. The confirm says exactly that and names the days being lost, rounded up so it never understates them, with distinct branches for an open-ended admin comp and a grant whose end date has passed rather than inventing a number for either.

Verification

Cold-reviewed independently, then a second round. 17 mutation runs across the two, 14 killed, and every survivor that represented real missing coverage now has a test.

Three defects the review caught, all fixed here:

  • Grammar at exactly one day"the 1 day left on it are not refunded". The verbs sat outside the plural branch, so only the singular was wrong: the case that fires for anyone converting near the end of their month. The copy tests now format the real en.json through IntlMessageFormat, because a test asserting only that days: 1 was passed stays green against a broken string.
  • A latent regression this change introduced — demoting the granted tier out of "owned" meant a tier with no Stripe product would vanish from the store rather than show a status. Not reachable with today's catalog, and the root cause is filed as OPE-441, but a missing card is worse than a dead one, so the demotion is now conditional.
  • An unasserted refreshbroadcastFreshUserMe() after a completed purchase could be deleted with nothing failing. That call is what stops the store offering a tier the player just bought, on the overlay path this whole cohort uses. Now asserted, with a paired negative test so an unconditional refresh cannot satisfy it.

The regression guards matter as much as the fix: a paid Stripe subscriber still reaches changeSubscriptionTier, a paid subscriber is still refused a duplicate of their own tier, and an older server's undefined provider is still treated as paid. All three are mutation-covered.

tsc --noEmit, lint and prettier clean. Full suite 5594 tests with one pre-existing load-dependent InventoryModal timeout that reproduces on a clean origin/main.

Filed, not fixed

  • OPE-441 — subscription tiles gate the buy button on the Stripe product block, so a Steam-only tier would be unbuyable on both rails. Same class as the OPE-231 fault already fixed for currency packs.
  • OPE-442 — the account modal still offers a granted subscriber no route to the store.

The new purchase-flow tests bypass the required full simulation setup and may miss integration regressions. Production behavior is otherwise covered, so this is a bounded test-quality risk.

Every Steam base-app buyer receives a granted month -- a subscription row
with `provider: null`, which nobody is billing. For that whole month they
had no way to pay us. The tier their grant confers rendered a dead
"Subscribed" box where the buy button goes, and every other tier routed to
`/subscriptions/@me/change-tier`, which answers 400 "Cannot change tier of a
granted subscription" because there is no agreement to reprice. At launch
that is the entire cohort, through the window where conversion is likeliest.

The server needs nothing: `/payments/checkout` already admits a granted
player on both rails (its exclusivity gate filters
`isNotNull(subscriptions.provider)`, so a granted row is never an incumbent),
and `startPurchase` picks the rail from the device, which is the only answer
a grant can have.

- `isGrantedSubscription` in ApiSchemas is now the single definition of
  "granted", replacing SubscriptionPanel's private copy (OPE-314). It keeps
  the three-state rule intact: `undefined` is an older server and must stay
  on the PAID behaviour.
- purchaseCosmetic routes a granted subscriber to checkout for ANY tier,
  including the one they hold -- buying that same tier is the likeliest
  conversion, and `already_subscribed` refused exactly that click.
- resolveCosmetics stops marking the granted tier "owned", so the store
  renders its buy button instead of the status box. A flare-unlocked tier is
  untouched. Subscription `relationship` is read only by the store, so
  nothing about the grant's current entitlements changes.
- A granted player is not counted as a subscriber for the "Switch" label:
  there is no paid plan to switch away from.
- New confirm copy, because the tier-change strings promise Stripe proration
  that does not happen here. Infra expires every granted row in the same
  transaction as the paid insert (`expireGrantsForPaidReplacement`), so the
  paid period starts at settle and the unused free days are gone -- no
  credit, no extension, no stacking. The string says so and names the days
  when `currentPeriodEnd` gives us a number; an open-ended admin comp gets a
  variant that quotes none rather than inventing one.

Tests cover the behaviour, not the markup, and include the regression guard
that a fix routing EVERYONE to checkout would fail: a paid Stripe subscriber
still reprices in place, and an older server's `undefined` provider is still
treated as paid. 12 of the new assertions fail on the unfixed build.

Cold review follow-ups:

- The confirm was ungrammatical at exactly one day ("the 1 day left on it
  ARE not refunded") because the verbs sat outside the plural branch. They
  are inside it now. Both strings also stop calling a grant a "month": only
  the Steam ownership grant is one, an admin comp is open-ended, and even a
  dated grant is not necessarily thirty days. New tests format the real
  en.json through IntlMessageFormat, because a test asserting only that
  `days: 1` was passed is exactly what let this through.
- Demoting the granted tier out of "owned" is now conditional on the tier
  having a Stripe `product`. Without one it falls to "blocked", and the
  subscriptions tab lists only purchasable and owned -- so the card would
  have VANISHED where it previously showed "Subscribed". Not reachable while
  every live tier carries a product, and OPE-441 is the real fix, but a
  disappearing card is a worse failure than a dead status box and this is
  not the PR to introduce it.
- Two mutation survivors killed: the profile refresh after a completed
  purchase is now asserted (without it an open store keeps offering the tier
  the player just bought, which is precisely the Steam overlay flow this
  cohort is in), as is the confirm heading.
- The paid-path tests no longer reach the network. `fetchCosmetics` is called
  from inside the module under test, so the seam is `fetch` itself rather
  than a vi.mock of a collaborator; unstubbed it requested a real
  cosmetics.json, which failed fast in jsdom and swallowed the error but was
  one DNS timeout from a flaky CI job. The stub serves a schema-VALID
  catalog, because an unparseable one leaves the current cosmetic null and
  silently defaults every confirm to "upgrade" — a new downgrade test is
  what proves the catalog is really read. The file went from 16.9s to 2.0s.

Review record — the repository's automated reviewer is out of quota, so this change was reviewed by three independent agent reviewers instead. Recording it here so the history doesn't read as though it merged unreviewed.

The review check on this PR fails with Claude result reported subtype success with is_error:true after ~21s and posts no verdict. That is repo-wide, not specific to this PR: the workflow last succeeded at 08:53Z on 12 Sept and has failed on every run since, across at least five branches.

What stood in for it:

Round Head Scope Outcome
1 a81a22d78 Full change, cold 17 mutations, 14 killed — 1 confirmed defect, 2 survivors
2 f671d16c1 Full change, cold, no priors disclosed 23 mutations, 20 killed — both survivors non-gaps; verdict: merge
3 b736387cd The remaining fix Network-reaching unit test removed

Each round found something the previous one missed, all now fixed: a test fixture seeding an admin self-grant while claiming to cover the Steam system grant; ungrammatical copy at exactly one day remaining ("the 1 day left on it are not refunded" — only the singular was wrong, and it is the case that fires for anyone converting near the end of their month); a latent regression where a tier with no Stripe product would have vanished from the store rather than showing a status; an unasserted post-purchase refresh whose removal broke no test; and a unit test making a real network call to cosmetics.json (16.9s → 2.0s once stubbed).

Two questions round 2 raised as potential blockers were resolved against infra, which the client-repo reviewers could not read:

  • Does the server admit a granted player buying the tier they already hold? Yes — the merged test at tests/api/endpoints/payments/checkout/POST.test.ts seeds a grant on the tier seedTier creates and then checks out that same tier by name, mutation-verified. Without this the fix would have moved the dead end one dialog later rather than removing it.
  • Does the product-gated guard strand Steam buyers? No — cosmetics.json builds product from the tier's Stripe listing and serves one catalog to every rail. The original bug report is the evidence: the other tiers rendered price buttons in the Playtest app, which requires product.price.

Rebased onto main after OPE-422 and OPE-445 landed; affected suites re-run green against the new global DOM teardown (82 passed).

## The bug

Every Steam base-app buyer receives a **granted** subscription month
(`subscription.provider === null`). While that grant was live, they had
**no way to pay us at all**:

- the tier they held rendered "Subscribed" with **no button** — no
request was ever made;
- any other tier failed with "Couldn't update your subscription".

At launch that is the entire cohort, for their whole first month — the
window where conversion is most likely.

The second symptom came from routing: a granted subscription fell
through to `changeSubscriptionTier`, and the server answers `400 "Cannot
change tier of a granted subscription"`. That refusal is correct and
stays — `change-tier` reprices an existing *provider* subscription, and
a grant has none. A granted player's tier selection is a **first
purchase**.

The API already admitted this on both rails (infra OPE-228/OPE-294); the
client simply never used the carve-out. Nothing server-side changes.

## What changed

**One definition of "granted"** — `isGrantedSubscription` in
`ApiSchemas.ts`, now shared by the account panel and the store instead
of each re-deriving it. It preserves the documented three-state rule for
`provider`: `null` granted, a rail string paid, and `undefined` (a
server predating the field) falling back to **paid** — the safe side at
every caller, since it keeps Cancel in front of a paying subscriber and
never sends one to a second checkout.

**Routing** — a granted subscriber reaches `startPurchase` for *any*
tier, including the one they hold. No rail check: a grant has no
`provider`, so the device decides, which is what `paymentsProvider()`
already does.

**The store tile** — a granted tier is no longer marked "owned", so it
renders a price button rather than a dead "Subscribed" label.

**Honest copy.** When a paid subscription settles, the server expires
the granted row in the same transaction: the paid period starts
immediately and remaining free days are forfeited outright — no credit,
no extension, no proration. The confirm says exactly that and names the
days being lost, rounded up so it never understates them, with distinct
branches for an open-ended admin comp and a grant whose end date has
passed rather than inventing a number for either.

## Verification

Cold-reviewed independently, then a second round. 17 mutation runs
across the two, 14 killed, and every survivor that represented real
missing coverage now has a test.

Three defects the review caught, all fixed here:

- **Grammar at exactly one day** — *"the 1 day left on it **are** not
refunded"*. The verbs sat outside the plural branch, so only the
singular was wrong: the case that fires for anyone converting near the
end of their month. The copy tests now format the real `en.json` through
`IntlMessageFormat`, because a test asserting only that `days: 1` was
passed stays green against a broken string.
- **A latent regression this change introduced** — demoting the granted
tier out of "owned" meant a tier with no Stripe `product` would vanish
from the store rather than show a status. Not reachable with today's
catalog, and the root cause is filed as OPE-441, but a missing card is
worse than a dead one, so the demotion is now conditional.
- **An unasserted refresh** — `broadcastFreshUserMe()` after a completed
purchase could be deleted with nothing failing. That call is what stops
the store offering a tier the player just bought, on the overlay path
this whole cohort uses. Now asserted, with a paired negative test so an
unconditional refresh cannot satisfy it.

The regression guards matter as much as the fix: a paid Stripe
subscriber still reaches `changeSubscriptionTier`, a paid subscriber is
still refused a duplicate of their own tier, and an older server's
`undefined` provider is still treated as paid. All three are
mutation-covered.

`tsc --noEmit`, lint and prettier clean. Full suite 5594 tests with one
pre-existing load-dependent `InventoryModal` timeout that reproduces on
a clean `origin/main`.

## Filed, not fixed

- **OPE-441** — subscription tiles gate the buy button on the Stripe
`product` block, so a Steam-only tier would be unbuyable on both rails.
Same class as the OPE-231 fault already fixed for currency packs.
- **OPE-442** — the account modal still offers a granted subscriber no
route to the store.
