Move the payment provider settings into their own file - #2114
Conversation
src/shared/db/settings.ts assembles the whole settings namespace, and it also held every payment provider decision: which provider takes new sales, which provider owns the payments that already exist, and the stored Stripe, Square, and SumUp credentials. That put one large statement and three credential namespaces in the file whose job is assembly, and it kept the file at 593 lines, well above the 400-line target. The provider code now lives in src/shared/db/settings/payment-provider.ts. It exports the getters to merge onto `settings` and the writers to spread onto `settings.update`, the same shape `stringAccessors` already uses. The behaviour is unchanged: the same statement, the same snapshot writes, and the same names on the namespace. withProperties moves to src/shared/db/settings/namespace.ts, because both files now merge parts that build their own getters. A spread cannot do this work. A spread calls every getter once, at assembly time. The tests move to the mirror path the mutation runner reads: test/shared/db/settings/payment-provider/activation.test.ts holds the provider choice, and credentials.test.ts holds the stored credentials. Ten test names in the moved credentials suite named helpers that the settings namespace replaced, so they now say what the behaviour is. settings.ts is 373 lines.

Three payment entries described work that is done: - The payment-provider split out of `src/shared/db/settings.ts` landed in the commit before this one. - `src/features/api/webhooks.ts` came down from 494 lines to 333 in #2065, so it is already below the 400-line target. - #2106 made `readSessionOrder` throw when a completed Square payment names an order that reads as missing, so the webhook is retried, not acknowledged. Each entry keeps its text and gains the outcome. A note that says a fixed bug is open sends the next person to fix it twice.

The branch mutation gate refused the new src/shared/db/settings/namespace.ts: it carries two mutants, and no test sat at its mirror path. Both mutants are real. One drops the Object.defineProperties call, so nothing merges. The other drops the return, so the caller gets undefined. The test pins the two things withProperties promises. Every property of the part reaches the target, and a getter stays a getter, so it reads the value at read time. A spread would freeze the answer instead. deno task mutation src/shared/db/settings/namespace.ts test/shared/db/settings/namespace.test.ts — 2 mutants, 2 killed.

TODO.md holds work that is still open, so a finished entry leaves it instead of staying in place marked "done". AGENTS.md now says so, and this change applies the rule to every entry the code already answers: - the payment-provider split out of `src/shared/db/settings.ts`, done in the commit before this one; - `src/features/api/webhooks.ts` below 400 lines, done by #2065; - a completed Square webhook whose order reads as missing, retried rather than acknowledged since #2106; - two suites covering the attendees list; - four feature modules that now have a test at their mirrored path. One entry was half open. The shared "reasons" shape shipped, but the surfaces it makes cheap did not, so the entry keeps the four open surfaces and the three decisions that bound them, and loses the record of what shipped. The stripe-mock port-steal entry stays: AGENTS.md cites it as the worked example for reading a written-down diagnosis, so it is documentation, not a job. The branch mutation gate found four survivors in the moved provider code. Two were real: - `changePaymentProvider` defaulted `first` to `false`. No caller reads that default, because only the credentials kind reads `first` at all, and that caller always passes the flag. The parameter is now optional with no default. - `settings.square.hasToken` moved into the new module, but its only test stayed in `public-api.test.ts`, which is not a direct test of that file. The mirror suite now covers the getter on both answers. The other two are one expression, `provider ?? ""`, and both are recorded in `scripts/mutation/equivalent-mutants/shared-db.txt` with their proof. No provider id is the empty string, so `??` and `||` agree. Only the disable kind takes the fallback, and the disable statement never evaluates a placeholder bound to that value. `deno task precommit:mutation` — 197 mutants, 195 killed, 2 suppressed, 100%.

Review of PR #2114 noted that the test read the merged values only, so an implementation that built and returned a new object would still pass. The settings namespace merges its parts one after another, each onto the object the last call returned, so returning the target is part of the contract.

Included review availability: 1 review is currently available. Your included PR review attempts over the past 7 days set your current allowance at 2 reviews per hour.
Review of PR #2114 caught the wording in the entry about splitting settings.test.ts. "Its describes already name the split" uses "describes" as a noun, which it is not. The entry now says "describe block" in both places. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EW4n7LWYByACzixWob1X21
CI failed one test out of 24,088 on this branch: "keeps a reserved port unavailable until release". The commit it failed on changed two lines of prose in TODO.md, which no test reads, and the commit before it passed the same test. The cause is not the diff. The test reserved a port, proved a second bind was refused, released the reservation, and then bound the same number again. Released means free to the whole machine. The suite runs in parallel, and every sibling that asks for port 0 can be handed that exact number in the window between the release and the re-bind, so the re-bind throws AddrInUse and the test fails. This is the hazard AGENTS.md names under "Tests That Share A Machine", and the one TODO.md has tracked since #1966. The re-bind now goes through retryWhilePortTaken, which asks again on a fresh reservation and gives up loudly after five steals in a row. Only AddrInUse is forgiven, so any other failure still fails the test. Proved both halves against a fake thief that takes the port the moment it is released: the old shape fails with AddrInUse, the guarded shape passes on its third attempt after two steals. The TODO entry records this third sighting. It stays open, because the wider fix it asks for — handing out ports so that no two tests in a run can receive the same one — is still not built.

Review of PR #2114 noted that the held-port assertion took a bare toThrow(), which passes on any exception. A Deno.listen that failed for an unrelated reason would have satisfied it without proving that the reservation held the port. It now asserts Deno.errors.AddrInUse, matching the check on the re-bind below it, which already forgives only that error. Checked that the matcher earns the change: @std/expect's toThrow accepts a constructor and compares the class, so a wrong class fails.

The statement that changes the payment provider was one `const sql` of five lines, each around four hundred characters, with twenty-four positional placeholders. The argument list was six sub-arrays flattened together, so reading it meant counting question marks against array positions. It now uses SQLite's numbered parameters, the pattern #2040 introduced for the two rate limiters and TODO.md asks to sweep across the bigger hand-built statements. `kind` was bound six times and `chosen` seven; each now has one slot. Nine values replace twenty-four. The SQL is broken into named fragments, each with a comment saying which rule it carries: CURRENT_PROVIDER, NOTHING_CHOSEN_YET, CREDENTIAL_SAVE_WINS, NEW_PROVIDER, NEW_LAST_ACTIVE, RECOVERY_ALLOWED, and ACTIVATION_ALLOWED. Two of them were spelled out twice inline and are now written once. The provider-to-credential mapping was a CASE with literal 'stripe', 'square', and 'sumup' arms. It is now an exhaustive Record keyed by PaymentProviderType, with the key list mapped off PAYMENT_PROVIDER_IDS, so the two lists line up by construction and a fourth provider is a compile error rather than a missing arm. The statement is built once at module load instead of on every call. No behaviour change. The same rows are written, the same guards refuse, and the same values are bound. The 23 activation tests, the credentials suite, and the wider provider consumers all pass unchanged, as do cpd, check:comments, lint:ci, and deno check. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EW4n7LWYByACzixWob1X21
The mutation gate left one survivor on the previous commit: the newline that joined the arms of a generated CASE. Nothing could kill it, because each arm already began with spaces and SQL reads any run of whitespace as one separator. That is the gate pointing at a construct doing no work. The CASE mapped the chosen provider to its credential key, but `changePaymentProvider` already holds the provider and CREDENTIAL_KEY_OF already holds the mapping, so the key is now bound as its own parameter and the CASE is gone. Behaviour is the same. A change that names no provider binds an empty key, which matches no row — and that path, switching sales off, never reaches the guard that reads it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EW4n7LWYByACzixWob1X21
Binding the credential key by hand moved the unkillable literal rather than removing it: the empty fallback for a change that names no provider now carries the same proof its two siblings already carry. Slot ?4 is read in one place, inside RECOVERY_ALLOWED, behind `?1 <> 'recover'`. Only the disable call omits the provider and takes the fallback, and for that kind the guard's left side is already true, so the row set is the same whatever the key holds. No input can tell the two apart. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EW4n7LWYByACzixWob1X21
CI failed "escalates repeated interrupts" on a commit that changed one text file in the mutation equivalents registry, which CI never reads. The cause is in the test, not the diff. forceStopChild removes the claim inside the guard body, and the guard still has to release its lock file before the .finally() that exits. The claim is therefore gone a whole filesystem operation before the exit is recorded. The test polled for the claim and then read exitCodes at once, so it could look in that gap and find nothing. The second symptom follows from the first: the test ends, `using` disposes the Deno.exit stub, and the pending exit reaches the real one, which is why the whole run reported exit code 130. The test now waits for the exit it is asserting. A model of the same ordering missed the exit in 49 of 200 runs on the old shape and 0 of 200 on this one.

Closes the first of the three deferred splits recorded under Payment
aggregate — safety behaviour (PR 1) in
TODO.md. PR #2020 named the targetpath and the mirror test folder, and deferred the move only because it would
have taken that PR past its 800-line source limit.
What changed
src/shared/db/settings.tsassembles the whole settings namespace. It alsoheld every payment provider decision:
already exist (
changePaymentProviderand the one statement that writes bothrows together);
settings.update.*writers.That code now lives in
src/shared/db/settings/payment-provider.ts. It exportspaymentProviderAccessors, which carries the getters to merge ontosettingsand the writers to spread onto
settings.update— the same shapestringAccessorsalready uses.withPropertiesmoves tosrc/shared/db/settings/namespace.ts, because bothfiles now merge parts that build their own getters. A spread cannot do this
work. A spread calls every getter once, at assembly time, and freezes the
answer it returned then.
Behaviour
No behaviour changes. The same statement runs, the same snapshot fields are
written, and every name on
settingsandsettings.updateis unchanged. Nocaller outside
settings.tsneeded an edit, because every reader already wentthrough the namespace.
One dead default went with the move:
changePaymentProviderdefaultedfirstto
false, but only the credentials kind readsfirstat all, and that calleralways passes the flag. The parameter is now optional with no default.
Current-system value
settings.tsgoes from 593 lines to 373, so the file whose job is assemblydoes assembly alone, and the provider rules sit in a file named after them. The
production callers are unchanged: the admin settings pages
(
/admin/settings/stripe,/admin/settings/square,/admin/settings/sumup),the provider activation and recovery forms, and every checkout, webhook, and
refund path that reads
settings.paymentProvider.Tests
The tests move to the mirror path the mutation runner reads:
test/shared/db/settings/payment-provider/activation.test.ts— the providerchoice, recovery, and the remembered provider. Moved out of
public-api.test.tsandsettings.test.ts.test/shared/db/settings/payment-provider/credentials.test.ts— the storedStripe and Square credentials. Moved out of
settings.test.ts,public-api.test.ts, andstripe-credentials.test.ts, which is deleted.test/shared/db/settings/namespace.test.ts— new, because the mutation gaterefuses a source file with mutants and no test at its mirror path.
Two gaps closed while moving:
settings.square.hasTokenmoved into the new module, but its only teststayed in
public-api.test.ts, which is not a direct test of that file. Themirror suite now covers the getter on both answers.
namespace replaced (
hasStripeKey,getStripeSecretKeyFromDb,updateStripeKey,getStripeKeyMode). They now say what the behaviour is.These stay direct Deno tests rather than becoming Cucumber stories. They assert
exact stored rows, the atomic statement's refusals, stale-request races, legacy
backfill, and ciphertext at rest — what E2E_TESTS.md calls a direct technical
contract. The organiser journey is already a story:
specs/payments/payment-provider-choice.feature.Two source files shrink as a side effect:
settings.test.ts747 → 651, andpublic-api.test.ts355 → 81.Also in this branch
TODO.mdholds work that is still open, so a finished entry now leaves itinstead of staying in place marked "done".
AGENTS.mdsays so under Afinished job leaves
TODO.md, and this branch applies the rule to everyentry the code already answers: the split above,
webhooks.tsbelow 400 lines(#2065), the Square webhook whose missing order is retried rather than
acknowledged (#2106), the attendees-list suites, and the four feature modules
that now have a test at their mirrored path. The shared "reasons" entry was
half open, so it keeps its four open surfaces and loses the record of what
shipped. The stripe-mock port-steal entry stays, because
AGENTS.mdcites itas a worked example.
