PaaS Incident Queue Storage and Retention

​

1. Queue Scope

1. contexts/<context>/events/incidents.jsonl

1. canonical incident payload
2. queue key (dedupe_key|window_start)
3. first/last seen timestamps
4. status
5. seen count

​

2. Retention Defaults

1. max_entries: 1000
2. max_age: 14d
3. collection scan limit per sync: 200

​

3. Retention Rules

1. Drop entries older than max_age by last_seen.
2. Sort newest-first by last_seen.
3. Truncate oldest entries when queue exceeds max_entries.

​

4. Upsert Rules

1. queue key is dedupe_key|window_start
2. same key updates existing row (seen_count++, last_seen refresh)
3. severity can escalate (info -> warning -> critical)
4. metadata is merged with sensitive-field redaction
