Voice analysis: Strong throughout. Part 1's "two-platform problem" framing gives the reader the mental model immediately — Apple and Google each run their own system, they share nothing, your server has to speak both. The progression from concepts → project setup → APNs → FCM → unified service → mobile clients → reliability → production is well-structured. Part 5's PushRouter trait with TokenStatus (Valid/Invalid/RetryLater) is a clean abstraction that makes the unified service feel inevitable rather than forced. Part 1's table comparing APNs vs FCM is a genuine use of a grid (comparing two platforms across multiple dimensions) — not a lazy list. No voice drift detected.

Highlights: Part 1's "why your server has to exist" explanation (you can't ship credentials in a mobile app). Part 5's PushBackend trait and TokenStatus enum design. Part 7's retry strategies with exponential backoff + jitter. Part 8's production hardening (connection pooling, health checks, constant-time API key comparison).

Status: 0 outstanding items. Maintenance mode continues.
