Permissions

Authorization lives in two places: graphql/public/permissions.ts (preferred) and inline in resolver functions (legacy). The goal is to move all auth into permissions.ts.

How it works

permissions.ts exports a permissionMap that maps GraphQL types/fields to shield rules. composeResolvers.ts wraps each resolver with its rule as a higher-order function — avoiding the overhead of graphql-middleware.

'*' wildcard sets a default rule for all fields on a type (e.g., all Mutations default to isAuthenticated)
Specific field entries override the wildcard
Rules can be composed with and(), or(), not() from graphql-shield

Rules directory: `graphql/public/rules/`

Rule	What it checks
`isAuthenticated`	viewer has a valid auth token
`isSuperUser`	viewer has `su` role
`isTeamMember`	`authToken.tms` includes the teamId (fast, no DB)
`isViewerTeamLead`	viewer has `isLead` on the team member record (DB)
`isViewerOnTeam`	viewer has an active (non-removed) team member record (DB)
`isTeamMemberOfMeeting`	viewer's `authToken.tms` includes the meeting's teamId (fast)
`isMeetingMember`	viewer has an actual `meetingMembers` record (DB, stricter)
`isViewerBillingLeader`	viewer has `BILLING_LEADER` or `ORG_ADMIN` org role
`hasOrgRole`	viewer has a specific org role (`ORG_ADMIN`, etc.)
`isViewerOnOrg`	viewer is a member of the org
`isOrgTier`	org is on a specific tier (`enterprise`, etc.)
`hasPageAccess`	viewer has `viewer` or `owner` access to a page
`hasProviderAccess`	viewer can access an OAuth provider
`isNull`	an arg is null (used for conditional or() rules)
`isEnvVarTrue`	an env var is set to true
`rateLimit`	rate limits by perMinute/perHour

Key distinction: isTeamMemberOfMeeting (used for createReflection) only checks team membership and is more permissive. isMeetingMember checks for an actual meeting member record and is stricter. Use isMeetingMember when you need to confirm the viewer has joined the meeting.

Dot-path convention

Rules that take a dotPath accept strings like:

'args.teamId' — top-level arg
'args.input.meetingId' — nested arg
'args.newAgendaItem.teamId' — nested arg
'source.id' — field on the parent resolver's source object
'source.orgId' — field on the parent resolver's source object

Moving auth from resolver to permissions.ts

When extracting inline auth:

Identify the auth check (usually guarded by a comment like // AUTH)
Find the matching rule or compose existing rules with and()/or()
Add the entry to permissionMap in permissions.ts (keep fields alphabetical, '*' first)
Remove the inline check from the resolver, along with any imports that are no longer used
If no existing rule fits and the logic is reusable, ask before creating a new rule — most cases can reuse existing rules

When a new rule is needed (ask first)

Auth that depends on an array of IDs (e.g., "team lead for any of these teamIds")
Auth that branches on an enum arg (e.g., scope === 'global' | 'org' | 'team')
