Found by accident on #208 and reported rather than resolved, because it was a
different question: adminAdjustBudget is exported from a "use server" module
and imported by nothing. In Next.js that is not dead code — every export of a
module-level "use server" file compiles to a POST target with a stable action
id
, so whether a component imports it decides whether a BUTTON exists, not
whether the ENDPOINT does. One instance found by luck is not a control.


1. The sweep, and what it covers

21 module-level "use server" files in apps/web/src, 89 runtime exports,
checked against an import graph of 2,402 edges over every file in the tree.

What the search sees: static import / export … from, dynamic
import("…"), side-effect imports, namespace imports (import * as ns) and
export * — the last two treated as referencing every export of the target,
on purpose. A <form action={x}>, a prop passed down, a re-export barrel and a
client-component binding are all covered, because each still needs some module
to import the name first. Both barrel and namespace paths were tested with
planted code and correctly reported reachable.

What it cannot see: a caller outside apps/web/src (Playwright specs drive
the browser rather than importing actions); a name resolved through a string at
runtime; a specifier that does not resolve on disk — that last case is
asserted empty so a new path alias cannot blind the guard quietly.

Result: 3 of 89 had no importer. git log --all -G over every page,
component and e2e spec in the repository's history shows none of the three
ever had one
— these are callers never written, not callers removed:

export file:line gate would write, if POSTed
adminRenameSeat app/(app)/admin/actions.ts:733 seat.manage Role.name, nothing else
adminAdjustBudget app/(app)/admin/actions.ts:1513 budget.override + stated reason Budget.allocatedCents, Budget.notes
leavePreviewPersonaAction app/preview/actions.ts:126 requirePreviewAccount a Preview.PersonaLeft audit row; clears the caller's own cookie

The other 86 all resolve to a rendered component, and 86/89 are reachable from
a route entry point by transitive walk. The three exceptions are the
lib/__fixtures__/form-refusal/* actions: they have real importers (fixture
pages) but no route reaches them, so they never become endpoints in the
deployed app.

app/page.tsx, signin/page.tsx, signin/pilot/page.tsx and
signin/activate/page.tsx declare inline "use server" closures. Those are
endpoints too, but they are defined inside the component that renders them, so
they cannot be orphaned in the way this is about — they are not in scope and not
enumerated.

2. Two got their surface

adminRenameSeat — a rename field on /admin/clubs/<slug>, inside the same
can.seat guard as the panel beside it. That panel has been telling operators
"Renaming the seat does not change it — this does" about a rename no screen
offered. No reason field: seat.manage is deliberately not on
CAPABILITIES_REQUIRING_A_STATED_REASON, and that exclusion is argued in
capabilities.ts — adding one here would re-litigate #208 in the wrong diff.

leavePreviewPersonaAction — a "Stop previewing" control on /preview. The
only previous way out of a persona was signing out, and signOutAction clears
the cookie through forgetPreviewPersona() without writing the
Preview.PersonaLeft audit row this action writes. The trail therefore recorded
every entry into a role and no exit from one.

3. The third is NOT deleted, and that is the finding

adminAdjustBudget is the only requireCapability("budget.override") site
in the tree, and budget.override is on
CAPABILITIES_REQUIRING_A_STATED_REASON, which
every-listed-capability-is-wired.test.ts asserts must have a call site — "a
listed capability with no caller is not enforcement, it is a list entry."

Measured, not assumed: the deletion was made, npx jest went red on exactly
that test, and the deletion was reverted. All three ways to make it green again
weaken a control to pass a cleanup:

  • drop the id from the reason list → a latent weakening; whoever wires the real
    budget override later gets no prompt and nothing tells them why
  • delete the capability → it names a power that IS exercised (below)
  • exempt it in the wiring test → weakening a control so a cleanup passes

The real defect, one level up

Budget.allocatedCents is read by nothing in apps/web/src. The only
db.budget.* calls in the tree are this action's own findUnique and update;
allocatedCents appears nowhere else outside schema.prisma and
seed-preview-world.mjs. Club money is BudgetLine + LedgerEntry now.

So every-listed-capability-is-wired passes on budget.override vacuously
the control is wired to a table nothing reads — while the power it names is
exercised somewhere else entirely:

canManageFinance (lib/rbac.ts:525) returns true for an OSE Director on
every club. A Director already rewrites any club's budget lines and ledger
through orgs/[slug]/finance/actions.ts, which gates on
requireFinanceManager (:147) — no capability gate, no stated reason
and writes its own audit rows.

Binding budget.override to BudgetLine is a product decision about whether a
Director must state a reason to touch a club's finances. It belongs in a diff
that argues it, not in a dead-code sweep. Evidence is recorded above the action
and in the guard's exemption entry.

4. The guard

apps/web/src/lib/__tests__/every-server-action-has-a-caller.test.ts — enumerates
the class and fails on an export nothing imports.

  • A spec importer is reported but not counted: a test is not a surface, and
    the question is whether the product leads to the endpoint. Free today — no
    action in the tree is imported only by specs.
  • The escape hatch is a declared list in the test file with a written
    justification, checked for rot: an entry naming an export that no longer
    exists, or one that has since acquired a caller, or one with an empty
    justification, all fail.
  • Why a hard failure: a warning about an endpoint nobody looks at is a
    warning nobody looks at. The declaration costs one line and a sentence, which
    is strictly cheaper than disabling the test — the failure mode a soft signal
    is really choosing between.
  • Why the list lives in the test and not as a pragma in the action: an
    exemption declared beside the action is buried in the middle of a
    1,700-line module; declared here it lands in the same diff as "we are adding
    an endpoint nothing calls."
  • Why "has an importer" and not "a route reaches it": the stronger property
    needs a transitive walk from route entry points and goes red on a component
    mid-refactor, which is how a test gets deleted. The weaker one catches the
    entire observed class.
  • Its own enumeration is asserted first (file/module/export/edge floors), so a
    scan that quietly stops finding things cannot pass by checking nothing.

Mutation testing

# mutation killed
M1 walker returns no files actually enumerated the tree
M2 export extractor returns nothing ✅ same
M3 "use server" detector always false ✅ same
M4 @/ alias fails to resolve ✅ 3 of 4 tests
M5 exemption names a non-existent export keeps no stale exemption
M6 exemption with an empty justification ✅ same
P1 planted orphan in an existing module ✅ named in the failure
P2 planted orphan in a brand-new "use server" module ✅ named
P3 planted export imported only by a spec ✅ named, "a spec is not a surface"
FP1 action reached only via a re-export barrel correctly stays green
FP2 action reached only via a namespace import correctly stays green

Two mutations killed NOTHING, reported rather than papered over:

  • M7 — counting spec importers as callers (removing the isTestFile filter)
    kills nothing against today's tree, because no action is imported only by a
    spec. That branch is exercised only by plant P3.
  • M8 — matching an exemption by name alone, ignoring the file, kills nothing
    today. Re-run as M8c with a same-named orphan planted in another module it
    does matter: the mutant passes, the real matcher catches it. So the
    file-qualification is defensive, justified by a demonstrated scenario, and not
    exercised by the current tree.

5. Related family — pairs writing the same state through different gates

Reported, not changed, per the brief.

A. Document.isArchived, two doors. adminSetDocumentArchived
(admin/actions.ts:1490) requires content.override and, since #208, refuses
without a written reason, landing it on an Admin.content.override audit row.
deleteDocumentAction / restoreDocumentAction
(orgs/[slug]/documents/actions.ts:119, :157) gate on canManageRoster,
which is isOseDirector(ctx, org.institutionId) || isActivePresident. An OSE
Director is a roster manager of every club
, so the same Director can archive
the same document through the club route with no stated reason, writing
Document.Deleted instead. Not a privilege escalation — both routes admit
Director — but the same "door beside the control" shape #208 fixed for
setClubStatus, still open on documents. Exposure is audit-trail integrity.

B. budget.override vs canManageFinance. Section 3 above. The larger of
the two.

Checked and found defensible: Organization.status (the #208 pair, now both
through club.archive); Event.status (event.override for a direct
institution-wide set, vs the approval chains where the status change is a
consequence of a decision, not a status write — lib/calendar-write.ts writes
title/venue/times and never status); MemoryRecord.isArchived (single writer);
User.institutionRole (each path has its own capability).

A note on reading the gate column: a scan of an action's own body reports
"no gate" for moveException, the finance actions and the memory actions.
That is a scanning artifact, checked by hand — they delegate to
moveException's requireCapability(capability, …), requireFinanceManager,
and lib/memory-moves.ts respectively. None of them is ungated.

…r surface

Found by accident on #208: `adminAdjustBudget` is exported from a "use server"
module and imported by nothing. In Next.js that is not dead code — every export
of a module-level "use server" file compiles to a POST target with a stable
action id, so whether a component imports it decides whether a BUTTON exists,
not whether the ENDPOINT does. One instance found by luck is not a control, so
this sweeps the class and then guards it.

THE SWEEP. 21 module-level "use server" files, 89 runtime exports, checked
against an import graph of 2,402 edges over every file in apps/web/src (static
imports, dynamic import(), namespace imports and `export *`, all resolved on
disk). Three exports had no importer, and `git log --all -G` over every page,
component and e2e spec shows none of the three ever had one — these are callers
never WRITTEN, not callers removed:

  adminRenameSeat              admin/actions.ts:733    seat.manage, writes Role.name
  adminAdjustBudget            admin/actions.ts:1513   budget.override, writes Budget
  leavePreviewPersonaAction    preview/actions.ts:126  writes Preview.PersonaLeft

TWO ARE GIVEN THEIR SURFACE.

`adminRenameSeat` now has a rename field on /admin/clubs/<slug>, inside the same
`can.seat` guard as the panel beside it — which has been telling operators that
"renaming the seat does not change it" about a rename no screen offered. No
reason field: `seat.manage` is deliberately not on
CAPABILITIES_REQUIRING_A_STATED_REASON, and that exclusion is argued in
capabilities.ts.

`leavePreviewPersonaAction` now has a "Stop previewing" control on /preview. The
only previous way out of a persona was signing out, and signOutAction clears the
cookie through forgetPreviewPersona() WITHOUT writing the Preview.PersonaLeft
audit row — so that trail recorded every entry into a role and no exit from one.

THE THIRD IS NOT DELETED, AND THAT IS THE FINDING.

`adminAdjustBudget` is the only requireCapability("budget.override") site in the
tree, and budget.override is on CAPABILITIES_REQUIRING_A_STATED_REASON, which
every-listed-capability-is-wired.test.ts asserts must have a call site. Deleting
the action turns that test red, and all three ways to make it green again weaken
a control to pass a cleanup. Measured, not assumed: the deletion was made, the
suite went red on exactly that test, and the deletion was reverted.

The real defect is one level up. `Budget.allocatedCents` is read by NOTHING in
apps/web/src — the only db.budget.* calls in the tree are this action's own —
so that wiring test passes on budget.override vacuously, while the power the
capability names is exercised somewhere else: canManageFinance (lib/rbac.ts:...)
returns true for an OSE Director on EVERY club, so a Director already rewrites
any club's budget lines and ledger through orgs/[slug]/finance/actions.ts, which
calls no capability gate and asks for no stated reason. Binding budget.override
to BudgetLine is a product decision about club finances and belongs in a diff
that argues it, not in a dead-code sweep. The evidence is recorded above the
action and in the guard's exemption entry.

THE GUARD. lib/__tests__/every-server-action-has-a-caller.test.ts enumerates the
class and fails on an export nothing imports. A spec importer is reported but
not counted — a test is not a surface. The escape hatch is a declared list in
the test file with a written justification, checked for rot (an entry naming an
export that no longer exists, or one that has since acquired a caller, fails).
It is in the test rather than a pragma in the action so the exemption lands in
the diff a reviewer is already reading, which is strictly cheaper than disabling
the test — the failure mode a soft warning would really be choosing.

Mutation-tested: blinding the walker, the export extractor, the "use server"
detector or the @/ alias each kills a test; a planted orphan in an existing
module, in a new module, and one imported only by a spec are each caught by
name; a stale or unjustified exemption fails. Two mutations killed nothing and
are reported in the PR rather than papered over.

CodeRabbit found three false negatives in the sweep — the direction that
matters, because a guard that over-reports is a nuisance and one that
under-reports is a hole. All three are planted-and-caught, not argued:

1. `isTestFile` matched `.test.ts(x)` but `CODE` admits `.mts`/`.cts`/`.mjs`,
   which jest's own `moduleFileExtensions` lists. A `foo.test.mts` outside
   `__tests__` therefore counted as a PRODUCT caller, so a spec could satisfy
   the orphan check. Planted `evadeViaMts` + a `probe.test.mts`: caught now,
   and with the old regex restored the same plant passes — the control.

2. `export default` was not extracted at all, so a default-exported action was
   never checked. It is now recorded under "default", which is the name an
   importer has to bind, and the import side records the default slot from
   `import D from` / `import D, { a }` rather than swallowing it into
   "everything". Planted an orphan default (caught) and an imported one
   (correctly green).

3. `import type`, `export type`, a `type x` specifier inside a mixed clause,
   `typeof import("…")` and a bare `import "./x"` were all counted as runtime
   edges. Every one of them is erased or binds no name, so a type reference to
   a same-named symbol made an orphan look reachable. The `type` keyword is now
   captured rather than skipped, mixed clauses drop their erased half,
   `typeof import` is excluded by lookbehind, and a side-effect import records
   no edge — while still being resolved, so a broken specifier still surfaces.
   Four separate plants, four catches.

Comment thread apps/web/src/lib/__tests__/every-server-action-has-a-caller.test.ts Outdated
The fourth reviewer finding on this guard is the same finding as the first
three: a TypeScript construct that spans lines, or carries unexpected
whitespace, slips past a line-oriented regex — and every miss makes an orphaned
server action look referenced, which is the one thing this file exists to
prevent.

The four, in order:
  · isTestFile did not know .mts/.cts/.mjs, so a TEST-only importer counted as
    a product caller
  · runtimeExports omitted `export default`, invisible to a guard on a version
    of Next that supports default server actions
  · `import type` / `typeof import()` were counted as runtime edges, so a
    TYPE-ONLY reference made an orphan look reachable
  · multiline `export { … }` was invisible, and `typeof` followed by more than
    four spaces defeated the lookbehind separating a type query from a real
    dynamic import

Patching a fifth regex buys a fifth hole. The compiler answers all of it
exactly, and it is already a dependency:

  · `typeof import("x")` is an ImportTypeNode — a TYPE node, structurally a
    different kind from the CallExpression a dynamic import is. Telling them
    apart needs no lookbehind and no whitespace assumption.
  · a named export clause is ONE node whatever its formatting.
  · `isTypeOnly` is a property, on the clause and on each specifier, rather
    than a prefix to be pattern-matched.

MY OWN REGRESSION FIXTURE CAUGHT A BUG IN THIS COMMIT. `export default function
go() {}` is a FunctionDeclaration carrying BOTH modifiers, not an
ExportAssignment, so the name branch matched first and recorded "go" — when the
only name an importer can bind is "default". Fixed, and the fixture that caught
it is one of the five kept.

The five fixtures assert against the parser directly rather than against the
tree, because the tree happens not to contain these forms today — and "no
example exists right now" is exactly the condition under which a hole survives
unnoticed.

MUTATIONS: blind the export-clause walk -> 2 tests die. Stop honouring
isTypeOnly on specifiers -> 1 dies. Both restored green.

tsc 0, lint 0, 281 suites / 4674 tests.

Addressed the fourth finding by replacing the parsing rather than extending it.

Both gaps named are the same shape as the three before them — a construct that spans lines or carries unexpected whitespace slips past a line-oriented pattern — so a fifth regex would have bought a fifth hole. The module is now parsed with the TypeScript compiler, which was already a dependency:

  • typeof import("x") is an ImportTypeNode, structurally a different kind from the CallExpression a dynamic import is — telling them apart needs no lookbehind and no whitespace assumption.
  • A named export clause is one node whatever its formatting, so the multiline case stops being a special case.
  • isTypeOnly is a property on the clause and on each specifier, rather than a prefix to be matched.

Five regression fixtures cover both named forms plus the mixed { a, type B } clause and both default-export spellings. They assert against the parser directly rather than against the tree, because the tree does not contain these forms today — which is exactly the condition under which a hole survives unnoticed.

One fixture caught a real bug in the fix itself: export default function go() {} is a FunctionDeclaration carrying both modifiers, not an ExportAssignment, so it was recorded as go when the only name an importer can bind is default.

Mutations: blinding the export-clause walk kills 2 tests; ignoring isTypeOnly on specifiers kills 1. tsc 0, lint 0, 281 suites / 4674 tests.

Assert this fixture through importGraph.

This test duplicates the CallExpression check from importGraph in a local walk function. It therefore validates the copy, not the shipped classifier. If the branch at lines 304-313 regresses, this test still passes. The neighbouring fixtures call runtimeExports directly, so they do guard the production path.

Write the two files into a temporary directory and assert on the edges that importGraph returns, so the type query produces no edge for ./actions and the dynamic import produces an everything edge for ./other.

MEASURED FIRST, because the premise could have been wrong. It was not.

`budget.override` — Director-only, on CAPABILITIES_REQUIRING_A_STATED_REASON —
had ONE requireCapability call site in the tree: `adminAdjustBudget`, writing
`Budget.allocatedCents`. Nothing in apps/web/src reads that table. The only
`db.budget.*` calls anywhere are that action's own findUnique and update, and
`allocatedCents` appears nowhere outside schema.prisma and the preview seed. So
`every-listed-capability-is-wired.test.ts` was passing on that id VACUOUSLY.

The power the capability NAMES was exercised somewhere else. Club money is
`BudgetLine`; every write to it went through `canManageFinance`, which returned
true for an OSE Director on EVERY club in the institution. Seven allocation
writes across `orgs/[slug]/finance/actions.ts`, zero requireCapability calls in
that file, zero stated reasons. A Director could rewrite any club's allocation,
retire any club's line, or replace a club's whole plan from a spreadsheet, and
the trail said only that somebody with finance authority did something.

THE FIX. `financeAuthorityOf` (lib/rbac.ts) now answers WHERE the authority came
from, not merely whether it existed: SEAT for the club's own ACTIVE president or
VP of Finance, OSE_OVERRIDE for a Director holding no seat in the club, null for
everybody else. `canManageFinance` is derived from it rather than restated, so
the two cannot drift into two answers to one question. The seat is asked FIRST,
so a Director who is also this club's treasurer is doing the club's own work and
is not interrogated — and the same person is still an override next door.

`requireFinanceManager` then routes an OSE_OVERRIDE through
`requireBudgetOverride` (lib/finance-override.ts) for the four writes that change
what a club may SPEND: Finance.EditLine, CloseLine, ReopenLine, Import. That is
`requireCapability("budget.override", { statedReason })` — the gate that already
existed, refusing on the server, writing a DENY row for a groundless attempt and
putting the operator's own sentence verbatim on the ALLOW.

NOT GATED, and each named rather than omitted: Finance.SaveForecast writes a
projection, never authority. Finance.PostLedger and Finance.ReverseLedger record
that money MOVED — both already refuse without a description, or a reason code
plus a note. Whether an OSE ledger posting is itself an override is a real
question and a separate one; it is stated in finance-override.ts and asserted by
name in the tests so deciding it later is a decision rather than a discovery.

THE UI EXTENDS THE PRECEDENT, and is not the control. `components/forms/
ReasonField.tsx` — the asterisk the onboarding decline already uses — gains an
optional controlled mode, because the add-a-line form asks "did you mean to
re-budget?" and resubmits itself, and React empties an uncontrolled box when a
server action resolves. The close dialog reuses the note it ALREADY refuses
without rather than asking the same person twice, raising only its floor from 8
to 12 for an override and saying so. Reopen was one click; for an override it
now opens a dialog. A club officer sees none of this.

PR #214's DECISION IS NOT REOPENED. `adminAdjustBudget` stays, exempted with its
written reason. What changed is the ground under the exemption: it is no longer
"the only wiring of a listed capability", so deleting it would no longer weaken a
control. Both stale sentences that said "delete this in the same diff" are
corrected, along with the sweep header that recorded it as deleted.

THE GUARD IS A CLASS CONTROL, not a check of today's call site.
`spending-authority-is-gated.test.ts` walks the AST of every tracked source file,
finds each Prisma write on BudgetLine/Budget whose payload carries an allocation
column (plus every create and delete), resolves it to the OUTERMOST enclosing
function, and requires that function to reach a gate. It also derives
BUDGET_AUTHORITY_ACTIONS from the source and compares it with the declared list
in both directions, so a gated write under a name nobody listed — a gate present
and inert — fails too. Payloads only, never `where`: postToLedger names
`closedAt: null` as a compare-and-swap, and counting filters would read every
guarded movement as a retirement.

FIVE MUTATIONS RUN, each md5-verified as applied and restored:

  strip requireCapability from the gate    → guard test 1 red, endpoint test 20 red
  unwire requireBudgetOverride             → "routes an OSE override" red
  new ungated write, same file             → named grantExtraBudget() at its line
  new ungated write, NEW file              → named bumpBudget() at its line
  gated write under an unlisted action     → named "Finance.RaiseLine"

NEIGHBOURING BRANCHES, asked deliberately: a Director with an EXPIRED seat here
is an override (tested — reading storedStatus would have let a past treasurer
keep editing). A third model carrying `budgetedCents` would be invisible to the
walk, so the scan reads schema.prisma and fails if one appears. Raw SQL sits
under $allOperations and no AST walk keyed on the model API sees it, so that is
checked too — from the SQL itself, because a file-level grep reported
lib/tenancy/registry.ts, which only mentions both in prose.

Delegation is deliberately NOT honoured: the finance write resolves no delegated
authority of its own, and opening that door would admit a delegate the command
then refuses.

CONCURRENCY: the existing `db.auditEvent.create` in requireFinanceManager is
untouched — the capability check is added AFTER it, and no audit write site was
restructured.

307 tsc errors (parity with main), lint clean, jest 3 failed suites (the same
three that fail on pristine main), 5578 passed.

NOT DONE, and not claimed: no Playwright spec. The finance page has no e2e
harness to extend and one written blind would be an overclaim; the server-side
proof is `an-ose-override-with-no-reason-writes-nothing.test.ts`, which posts to
the exported server actions with no form and asserts no statement was issued.
