raspi-sentinel v0.5.0

Released: 2026-04-17

Highlights

Added robust deferred notification delivery for Discord:
- network/transient delivery failures are aggregated in state backlog
- retry attempts run on notify.discord.retry_interval_sec (default 60s)
- recovery sends one summary message with outage window (delivery_failed_from / delivery_failed_until)
Added retry_interval_sec to Discord notify config schema and validation.
Expanded network_uplink reasoning and observability:
- layered reason/subreason evidence (route/gateway/wan decomposition)
- clearer DNS/HTTP error kind classification
- stronger null-vs-false evidence handling in outputs
Strengthened typed runtime model usage and removed remaining mixed raw-dict mutation paths in core runtime flow.

Enforced strict typing workflow (mypy --strict) in project/CI path.
Expanded integration and branch tests across config, engine, notifications, and state serialization.
Verified full quality gate (ruff, mypy, pytest, coverage branch gate).

retry_interval_sec = 60

No manual migration is required for existing state.json; new notification backlog fields are backward-compatible.
For operators: see docs/facts/operations-runbook.md section "Notification Delivery Outage Runbook" for troubleshooting and interpretation.
