The summary now covers the whole lifecycle: buying, renewing, changing
tier, moving to another device or profile, and ending. The badge retires
as soon as the store says the subscription ended, a lapsed iOS subscriber
can resume the retired badge, an App Store raise is granted at once and
a lower tier at the renewal, and a Play plan change is a new purchase.
The known limits and the before-sale list follow the code.
The seven diagrams are updated, with stale file and line references
dropped, and two are added: a tier change and a restore. The page now
points at the diagram files instead of carrying copies of them.
The RPC document splits a store tier change by store and direction: the
app never starts one, an App Store raise seen within a day of its charge
is sent as upgradeBadgeSubscription, every other change waits for the
renewal check, and a Play plan change is a new token, a new purchase.
transferBadge and its limits are checked against the handlers, and the
upgrades that are not built are marked so.
The overview admits what Restore discloses: the service links the two
purchase keys, a store receipt moves its subscription to whoever presents
it within the move limit, and a new badge or tier is shown as soon as it
is issued. The Android gap names what remains of Restore.
A Supporter charge handed over while Legend is shown is answered from the record and sends nothing, and the renewal check grants Supporter, shown once the Legend credential expires; a record an older build held for a lower tier settles with no request. Both fail if every change of tier is sent at once again.

Apple keeps charging the old plan to the end of the period, so applying a downgrade at once took away a badge the subscriber had already paid for. A charge of another tier is now held and sent at once only from supporter to legend; a lower tier, or one that is not ranked (investor, unknown), is answered from the record and the renewal check grants it, as badges-rpc.md says. A record already held for such a change settles silently.

- R3-1: a tier change whose answer says the subscription ended is not credited, as a resume is not, so the credit's clearing of a stored ended never drops the one this answer carries.
- R3-2: the changeTier comment in two lines.
Run: 015-badge-fixes, review round 3
- R2-1: a granted tier change clears an ended state the device reported before it. A renewing report never replaces ended, and a charge of the new tier granted proves the subscription has not ended, so without this the worker retired the new tier's badge at its paid-through while the subscription renewed.
- R1-B3: test a tier change whose credential does not verify: the failure stays on the receipt record, not the purchase, and Supporter stays shown.
- R2-3: the refused tier change's test buys Supporter through an invoice, so it shows the refusal announces nothing.
- R2-2: the changeTier comment says what follows each way the record settles.

The App Store tier-change hold, reviewed for the first time:
- R1-B2: a tier change's credit now shows its purchase again (shown_badge_id) in the same transaction, as a resume's does, so a retire that ran while the change was with the service cannot leave a paid purchase unshown and never renewed.
- R1-B5: a tier change of a shown purchase is held whatever other receipt is held, as the worker serves it while the badge is shown; only a resume waits for other held receipts.
- R1-B3: test a tier change the store does not vouch for: refused in silence, the badge kept, and answered from the record after.
- R1-B8: the changeTier comment names when the record settles.

After a tier change the newer issuance can end before the older one, so ordering issuances by period end would answer the superseded credential to the worker and to the resume and tier-change paths. Pin the row order: the test fails if the query goes back to period_end order.

Play reports only a period's end, and the service dates the charge a plan length before it, so month-end clipping could leave a charge funding less than its month. Walk a monthly and an annual Play plan anchored on 31 January through their renewals at the device's request moments, through the deployed Play verifier: each charge funds exactly its months, paid-through stays at most the grace behind Play's period end (three days at most in this walk), and no charge is left without a grant.

A pass announced the badge state only when the balance start moved, so a charge granted onto running coverage, or a debit the service wrote, changed months left and paid-through without an event, and the apps kept showing the old renewal date until the screen was reopened. The pass now announces whenever the ledger's last entry is not the one it started from, which a moved balance start implies.

The iOS app refused any subscription to an Apple ID that ever subscribed, so a lapsed subscriber could never subscribe again in the app. Core now tells the apps each subscription's store reference (BadgeSubscription.transactionRef, optional in JSON), and the iOS gate opens a subscription card only when every earlier subscription of the Apple ID is the active profile's newest purchase, retired, of the card's badge: the one charge core resumes. Kotlin gets the model field only, as Play gives a resubscription a new token and needs no gate.

Review round 1 fixes:
- R1-1: a resumable charge waiting behind another held receipt of the owner is answered held and left unfinished, rather than answered from the record and finished uncredited.
- R1-3: a resume shows the purchase again only with a credential that has not expired.
- R1-2, R1-8: tests of the resumable-charge rule and the hold's edge, of a held charge whose paid period ends before it is sent, and that a resumed profile shows the newest credential. The resume test is split in two, one environment each.
- R2-V1: a test comment that the reordered steps made false.

A same-install resubscription keeps Apple's original transaction id, so its hand-over found the old credited record and was answered from it with the old credential: the subscriber paid and got nothing. A credited record is now held again when a later charge of its subscription is handed over, the charge is not revoked, its paid period runs and it is dated less than a day ahead of this device's clock, and the record's purchase is its owner's newest, a subscription and not shown, with no other receipt held. The receipt worker then sends the purchase's issueBadge, and the service grants the charge as a renewal. A covered answer shows the purchase again with the newest credential and clears an ended state. A charge the service answers without crediting is deferred an hour and refused a day after its purchase date, so it holds the profile for about a day. A refused resume is remembered on the record (every credit, re-hold and resume clears credit_error), so the app's sweep does not hold the same charge again after its day.

StoreKit can report a subscription expired during Apple's billing retry, and Apple may then recover the charge, so retiring at once on that report left a paying user without the badge. The service's answered ended still retires at once, also while the ledger covers. A stored ended, which is how the device's report arrives, retires once paidThrough has passed.

The receipt worker's attempt already holds the owner's badge lock, which is not reentrant, so it cannot call requestBadgeIssue. The body becomes sendBadgeIssue, and both answer a service error as Left (code, retryAfter) instead of Nothing, so that caller can classify it as it does today. No behaviour change.

/_badge request <userId> sends the profile's badge request now, while
its badge is shown, and runs the badge pass on the answer, so a renewal
or an ended subscription can be watched by hand against the dev
service.
It is allowed only when ChatConfig's badgeDevRequests is set, which no
shipped build does and nothing sets at runtime: the dev-service branch
sets it beside its own badge service overrides. A request off the shared
expiry would tell requests apart, so every other build refuses it, and
it is refused from a paired remote controller.

[dev] check_store_during_coverage = on makes every issueBadge for a
subscription ask the dev mock, during paid coverage too, and bank the
month of a charge it can grant, issued once coverage reaches it. So a
renewal can be watched by hand without waiting a month, and a mock that
forgot the plan after a restart answers ended at once.
Off by default, and refused unless accept_unverified_store_receipts is
on, which is itself refused beside a real store: a real store has not
started its next charge while coverage runs, and asking spends the
quota every subscriber shares.
