Two Important findings from review, both against the plan's own text.
The frozen-booking test could not fail for a defect this diff introduces.
Digging into why turned up two problems, not one. The two assertions the
review named were never exercised: sync-catalogue never writes
subscription_addons.stripe_price_id, and the orphan planted for the new
figure sits at a different amount than the booking's own price, so
archiveSuperseded's net_cents scoping was never going to reach it either.
Underneath that, the test's own orphan was inert regardless of any of that:
with no StripeAddonPrice row seeded first, AddonPrices::product() minted its
own Stripe Product instead of reusing 'prod_support', so the competing
orphan planted under that literal id sat on a product nothing ever asked
about. Fixed both — seeded the product the way the first two tests in this
file already do, added the three assertions the review specified, and a
comment on what the two original assertions do and do not prove.
Verified the fix actually bites, since a test whose teeth are asserted but
never demonstrated is what produced this finding in the first place. With
just the amount check in AdoptStripePrice disabled, the booking still
survived: the `claimed` callback this diff wires into AddonPrices::ensure()
caught it as a second, independent guard. Only disabling both together
reproduced the failure — the honest demonstration, not the single-line
sabotage first suggested, which this diff's own defense-in-depth absorbs.
The remember() comment credited a unique index stripe_addon_prices does not
have — that index sits on stripe_plan_prices, the plan side. Reworded to
name what actually keeps two rows off one Price id today (the `claimed`
callback), what 2026_07_31_210000_one_row_per_stripe_price adds as a net
under it, and why two rows sharing one Price is dangerous: archiving one —
the ordinary response to a superseded figure — would withdraw the very
Price the other row is still selling.
