Node 20 was deprecated 2026-04-30 and deploys are blocked after 2026-10-30. nodejs22 is GA
for BOTH gens (deprecation 2027-04-30) — required because the runtime is codebase-wide and
onUserDelete stays gen1. nodejs24 was checked per plan and rejected: 2nd-gen only.
- functions/package.json engines.node 20 → 22 (the deploy-facing change; dist unaffected)
- .github/workflows/backend-ci.yml: both setup-node pins 20 → 22 so CI matches prod
Verified pre-deploy: tsc clean, 70 tests green, emulator discovery loads all 35 / 0 errors.

Bump firebase-functions ^5.1.0 → ^7.2.5. The whole codebase now uses the v2 API
(firebase-functions/v2/*) with onUserDelete explicitly on firebase-functions/v1, so the
v6/v7 removal of the root v1 namespace is a no-op for us. firebase-admin unchanged (v7 does
not peer-require a bump).
The plan assumed v6 was latest; the actual latest is v7.2.5 (v7 released after the plan was
written). Verified under v7: tsc clean, 70 tests green, emulator discovery loads all 33
functions in us-central1 with zero errors and the "outdated firebase-functions" warning gone
(v6.6.0 still tripped that warning).
