Phase 20 Plan 01: Member-profile update route + isAdmin read Summary

PATCH /api/admin/members/:id with displayName/isAdmin partial update, D-03 last-admin guard (409), and isAdmin added to GET /members — implemented test-first.

Tasks Completed

Task	Name	Commit	Files
1	RED — failing tests for member-profile route + isAdmin read	a0a82ac	apps/api/tests/routes/admin.test.ts
2	GREEN — implement PATCH /members/:id + isAdmin in GET /members	bc48632	apps/api/src/routes/admin.ts, apps/api/tests/routes/admin.test.ts
3	REFACTOR — tidy + pass CI gates	(no changes needed)	—

What Was Built

• PATCH /api/admin/members/:id route in apps/api/src/routes/admin.ts:
  • Accepts { displayName?: string; isAdmin?: boolean } via updateMemberSchema
  • Protected by router-wide requireAdmin (no second guard — D-02)
  • parsePositiveIntParam rejects malformed ids → 400
  • Existence check → 404 for unknown member ids
  • D-03 last-admin guard: when demoting the only admin → 409 { error: 'Cannot remove the last admin' }
  • Self-demotion with a second admin present → 200
  • Partial set() from whichever fields are present; try/catch 503 fallback
  • noEchoHook applied per T-20-04 consistency posture
• isAdmin field added to GET /api/admin/members select and mapped response object

Test Coverage (8 scenarios, all passing)

Test	Scenario	Status
A	displayName update → 200; GET reflects change	GREEN
B	isAdmin promote → 200; GET shows isAdmin true	GREEN
C	Last-admin demotion → 409; member stays admin	GREEN
D	Self-demotion with second admin → 200; one admin remains	GREEN
E	Non-admin PATCH → 403 (requireAdmin boundary)	GREEN
F	Wrong-type body → 400 Invalid request; malformed :id → 400	GREEN
G	Non-existent member id → 404	GREEN
H	GET /members includes boolean isAdmin per member	GREEN

Full suite: 44 tests passed, 0 failed.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Test D GET called with demoted user

• Found during: Task 2 (GREEN run)
• Issue: Test D called GET /members while currentDevUserId was still adminId1, who had just been demoted — resulting in 403 instead of 200 for the verification GET
• Fix: Switched currentDevUserId = adminId2 before the GET call so the verification uses the remaining admin's session
• Files modified: apps/api/tests/routes/admin.test.ts
• Commit: bc48632

CI Gates

All gates pass for modified files:

• tsc --noEmit: pass
• eslint src/routes/admin.ts: pass
• prettier --check: pass (both files)

TDD Gate Compliance

• RED gate commit: a0a82ac (test(20-01): ...) — 7 tests failing for right reasons
• GREEN gate commit: bc48632 (feat(20-01): ...) — all 44 tests passing
• REFACTOR: no code changes needed — code was already clean from GREEN

Known Stubs

None.

Threat Flags

None — no new network surfaces beyond the planned PATCH route. All T-20-xx mitigations applied as specified.
