Declare each admin route once, and check every page lets in who it says - #2113
Conversation
Five sweeps looked for shape-level repetition across the codebase. The admin surface keeps a hand-made map of its own routes in six places, with no check that ties the role in the map to the role at the handler. The plan makes each fact one declaration and derives every consumer from it. TODO.md gains one verified finding from the survey: Square reports a malformed payment link as an unconfigured provider.

The admin surface kept a hand-made map of its own routes in four tables. An area now declares its routes once, with the role that reaches them stated once for the area. The destination map, the segments each area serves, and the navigation all derive from that declaration. Two facts stop being repeated. An area's audience was written on every route it owns, 121 times across the tables; it is now written 43 times, once per area. The segments an area serves were a second 43-entry map beside the loader map; they now come from the patterns the area declares, with 'segments' left only for a route that has no page of its own. The section a route sits in was declared on all 111 destinations, but only the 42 with navigation ever read it. Sections now name their own routes in the order a reader sees them, so the order is explicit instead of implicit in the position of an entry in a 383-line file. Proved faithful by comparing the derived destinations, segments, and per-section navigation against the old tables: all 111 routes, 43 segment lists, and 12 navigation orders are identical.

The surface says which roles reach each page, and each handler enforces its own policy. Nothing checked that the two agree. A new check walks every page whose pattern takes no parameter and asks it as all four roles. A role outside the audience must never be served the page. A role inside it must never be forbidden. It is written about being served and being forbidden, not one exact status, because a page whose feature is off answers 404 to everyone, which is still a refusal. It found one disagreement. The deliveries run sheet declared staff only, but GET /admin/deliveries is gated by deliveryPage, which admits agents, and its comment calls the run sheet an agent's only page. So adminDestinationAllowed gave the wrong answer for every link to it. The declaration now says DELIVERY_ADMIN_LEVELS, which matches what the handler has always enforced. No access changed. Reverting that one line fails the check with 'deliveries served agent'. Three test files move to mirror the source they cover, so each is mutation-tested against its own file, and the fold gains direct unit tests of its own.

The replace callback took a plain string and cast the parameters to a loose record. Naming the key type keeps the same check the rest of the module relies on, with no cast. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019DqY181KZ5hBa6gEUKvFYJ
The fold wrote each route into a map keyed by id. Two areas using one id left the loser unreachable, with every link to it pointing at the winner. The fold now names both areas and stops. The areas table also gains its own tests: every route sits under /admin, names roles that exist, and can be reached by at least one of them; every route belongs to a declared area; and the paths other modules type by hand keep their values.

Every link names a route from the areas table, so the checks that matter are about that tie: each link points at a route that exists, each section opens with its own landing link, only that link is the landing kind, and each route is linked from one section only. One rule guards read-only mode. It hides a link by the intent of the route behind it, so an add or import link pointing at a view route would stay clickable with writing switched off. The two section tests move here from the surface test, next to the table they are about.

The gate mutates every changed file, and 42 mutants lived through the first run. Each is now covered by a test about the behaviour it breaks: - The navigation words: every section and every link names a message the English catalog defines, so an empty or misspelt key fails. - The record pages: only listings and groups have one, both keep it to staff, and both keep the exact path entityReturnPath rewrites. - The navigation model: a section holding one link shows no sub-navigation, an add link disappears while the site is read only without taking its siblings with it, and a link the viewer's role cannot reach stays hidden. - Admin dispatch: a signed-out visitor is sent back to /admin but still reaches the login pages, a signed-in one gets the page, and the footer that exposes the query log opens for staff and stays shut for an editor. That last rule was written in a comment and checked by nothing. Two survivors are equivalent and recorded: the fallbacks in groupDestinations and declaredSegments both take an object or an array, which is always truthy, so only undefined ever reaches them.

Every other signed-out admin page is sent back to /admin. The check-in endpoint must not be: the scanner reads the answer as JSON, so a redirect would reach it as a page it cannot parse. Nothing covered that branch, because a signed-out page redirects whether the dispatcher refuses it or the route's own guard does. The check-in path is where the two differ.

The test asked for a settings page twice while signed out. Dispatch refuses a signed-out visitor before it ever builds the segment's router, so both hits answered 302 whether or not a segment can reuse the router it built the first time. Both hits are now signed in and answer 200, which is the reuse the test is named for. The plan also said the declared audience already builds each handler's gate. It does not yet; Slice 3 does that. What is true today is that the role matrix proves the two agree. Both found by CodeRabbit on #2113.

The security note claimed the matrix proves the declared audience and the handler's gate agree, without saying for which pages. It covers the 48 whose pattern takes no parameter. The other 63 answer about one record, and a missing record answers 404 whatever the role is, so each needs a fixture before it can be checked. The test now states that split itself, so the document cannot claim wider cover than the suite has. Found by CodeRabbit on #2113.

What changed
The admin surface kept a hand-made map of its own routes: 111 entries across
four tables, naming a path, a role, an area, a section, and a read or write
intent that the real route tables and handler guards named again. Nothing tied
the two together except a test and care.
An area now declares its routes once, in
src/shared/admin-surface/areas.ts. The route map, the segments each areaserves, and the navigation all derive from that declaration. A new check then
asks every page who it lets in, and compares the answer with what the surface
says.
The value, and the caller that gets it
Two facts stop being repeated:

differs from the rest of its area.

deliveryPage, which admits agents, and its own comment calls the runsheet "their only page". An agent could open the page while the surface said
they could not, so
adminDestinationAllowedgave the wrong answer for everylink to it.
The declaration now says
DELIVERY_ADMIN_LEVELS, matching what the handler hasalways enforced. No access changed — only the answer the surface gives
about it. This overrules the plan's "stricter side wins" default on purpose:
the strict reading would take the run sheet away from the agents it was built
for. Reverting that one line fails the new check with
deliveries (/admin/deliveries) served agent.Two things differ from the approved plan

Trusted and observed facts
The declaration is now the single expected map. The route tables and handler
guards remain the observed authority for what exists and what is enforced, and
the tests below compare the two rather than assuming they agree.

test/integration/admin-role-matrix.test.ts— the backwards check. Everyparameter-free page, asked as all four roles: a role outside the audience is
never served the page, a role inside it is never forbidden. Written about
being served (200) and forbidden (403) rather than one exact status, because
a page whose feature is off answers 404 to everybody, which is still a
refusal.
test/shared/admin-surface/definitions.test.ts— the fold: area defaultaudience, per-route override, intent by group, segments derived from
patterns, extra segments, an area with no routes, and a table that declares
one route twice.
test/shared/admin-surface/areas.test.tsandsections.test.ts—the declaration's own rules, including that every label names a message the
English catalog defines, and that every add or import link points at a write

pin two rules that were written in comments and checked by nothing: only
staff get the footer exposing the query log, and the scanner's check-in
endpoint answers JSON rather than the sign-in redirect every other page gets.
One safety rule was added while closing the gaps: the fold refuses a table
that declares one route id twice, which would have left the loser unreachable
with every link pointing at the winner.
