…list Whether a site is over any of its limits is asked without naming one, so every limit has to be able to answer it. An allowlist limit cannot, because it judges one particular value and the question carries no value, so it raised an incorrect-usage error that escaped the sweep entirely. A site that limits which themes it may use, which is every hosted site, could therefore not answer the question at all. Those limits are now passed over rather than asked. The pin that recorded the old failure now records the answer, and the rethrow it used to reach incidentally is covered by naming the limit directly instead.
The number of whole periods since a subscription started was allowed to come out negative, which happens when the start date has not arrived yet: a subscription beginning later today, or a host clock running a little ahead of ours, is enough. The period was then anchored before the subscription existed, so sending from before the site was ever subscribed counted against the current allowance. Nothing has elapsed in that case, so the current period now begins at the start date itself.
Only a limit that resets has a period to count within, so a host capping emails outright rather than per period leaves the count with no date to narrow by. On the server that made the query builder refuse to build the query, and in Admin it made formatting the absent date throw. Both reached the publisher as a failed send rather than as a refused one, and Admin told them their sending was disabled because of an invalid time value. The whole history is what a plain maximum caps, so the period is now only applied where there is one.
The package was moved into Ghost with its history rather than copied, but git log --follow cannot reach the commits from before the move because it does not traverse the merge that brought them in, so following a file stops at the move into src. The README now says where to pick the history back up and which commit to ask from.
That suite was written to pin what a host limit does to a site before any of this moved, at a point when the package had no tests worth trusting and no way to reach Ghost's configuration. Some of what it recorded was never about a site at all: whether an unbuildable limit takes the others down with it, whether a periodic limit registers when its start date cannot be read, whether a name nobody declared is ignored. Those are answered by building a service, and now that the package is here and typed, that is where they are answered. The ones about Ghost's own wiring move beside it, to the suite that already covers loading a host's configuration. What is left asserts only what a caller receives through the API, which is what the suite says it does and the only thing in this repository that proves limits work rather than that Ghost calls a stub.

Host settings arrive from Ghost(Pro) as strings in a single column, and nothing read them before handing them to the limit service. A maximum that is not a number survives that journey intact and then compares false against every count, so the limit reads as configured, is charged for, and is never enforced; the only way anyone finds out is a customer exceeding a limit they were sold. Reading them now happens in one place, which decides everything that makes a limit usable: whether its values can be read, whether a counted limit has anything to count, whether a list has anything on it, and whether a limit that resets has a period to reset against. The service takes what was read rather than raw configuration, so it can assume the limits it is handed already work, and the type it accepts can only be produced by reading a host's settings. How to count what a limit measures is passed apart from the configuration, because it is behaviour rather than configuration and a browser counts differently to a server. None of this can stop a site starting. A limit nobody can use cannot be applied either way, and refusing to boot over one would take a site off the air for a mistake made elsewhere, so each limit is read on its own and the ones that cannot be used are set aside and logged at error level. That also ends one limit taking every other limit down with it, which used to leave a site unlimited in ways nobody chose. ref BER-3952

Closing unmerged. The compliance goal this stack followed on from already shipped in #30637, and the faults fixed here could not be shown to reach production: the limits they depend on are set on none of the billing products, and one of them fixes a method with no caller in Ghost at all. That left preventive value against risk in the path that decides whether a customer can publish. The branch stays on the remote. Findings from the production check, including the Daisy and Zuul transform chain and what was never verified, are recorded on BER-3952: https://linear.app/ghost/issue/BER-3952/bring-limit-service-onto-the-package-golden-path |

Last of the stack, on top of #30778. The faults the conversion recorded, each fixed on its own, and then the reason they were able to hide.
Problem
A site that restricts which themes it may use cannot answer whether it is over any of its limits. The question names no value, an allowlist limit judges one particular value, so asking it raises an incorrect-usage error that escapes the sweep entirely. Every hosted site has such a limit.
A subscription whose start date has not arrived yet counts sending from before the site existed against its current allowance. The number of whole periods elapsed was allowed to come out negative, and a subscription beginning later the same day, or a host clock running slightly ahead of ours, is enough.
A host that caps emails outright rather than per period breaks sending rather than limiting it. Only a limit that resets has a period to count within, so a plain maximum leaves the count with no date to narrow by: on the server the query cannot be built, and in Admin the absent date cannot be formatted. Both surface to the publisher as a failed send.
Underneath all three, nothing read a host's settings before applying them. They arrive as strings in a single column and were handed to the service as they came, so a maximum that is not a number survives intact and then compares false against every count. The limit reads as configured, is charged for, and is never enforced. The only way anyone finds out is a customer exceeding a limit they were sold, and by then nothing in a log explains it. Worse, one limit a host got wrong took every other limit down with it, because building stopped at the first one that could not be built and the limits configured alongside it never loaded at all.
Solution
Pass over the limits that cannot answer the sweep, rather than asking them. Let nothing elapse before the start date, so the current period begins there. Apply the period only where there is one, on both server and Admin, and refuse a start date that cannot be read rather than counting from it.
Then read a host's settings in one place, and let that place decide everything that makes a limit usable: whether its values can be read, whether a counted limit has anything to count, whether a list has anything on it, and whether a limit that resets has a period to reset against. The service is built from what was read rather than from raw configuration, so it can assume the limits it is handed already work, and the type it accepts can only be produced by reading a host's settings. How to count what a limit measures is passed apart from the configuration, because counting is behaviour rather than configuration and a browser counts differently to a server.
What a misconfigured site does now
Nothing a host can configure stops a site starting. A limit nobody can use could not have been applied either way, and refusing to boot over one would take a site off the air for a mistake made elsewhere. Each limit is read on its own, the ones that cannot be used are set aside, and every one of them is logged at error level with the limit named and the reason given, because a limit that is configured, charged for and then not applied is otherwise invisible.
That also ends one limit taking the others down with it. A site keeps every limit its host got right.
Measured
Every billing product in production was read through this and built into a service. None was refused, none lost a limit, and the one limit name Ghost(Pro) sends that this version has never heard of is passed over rather than treated as a mistake.
The behaviour of a well-formed configuration is unchanged throughout: the same limits apply, at the same thresholds, with the same answers.
How to read it
One fault per commit, each with its tests, each passing on its own and each revertable without the others, and then the change to how settings are read.
Where a test recorded a fault it now records the answer, and says what it used to say. The cases the package can answer for itself have moved into it, out of Ghost's own limits suite, which keeps the ones that are about Ghost's wiring rather than about limits.
Admin and Ember both lose code to this. Neither has to take apart what it was handed any more, and one of them loses a helper whose only purpose was to work around a limit failure taking the rest down.
Not doing
The package still holds a database it does not need, which is why Admin builds an emails limit it can never check. Moving the counting out is the larger change and is tracked separately.
Limits a host sets on one site rather than on a product have not been read through this. That needs customer data rather than the product catalogue, so it is worth doing before this is rolled out widely.
