What the data means

• One event, many posts. An official post, a team member's relay and reposts describing the same reset are merged into one record with several sources. Only records with kind = usage_reset and event_status = confirmed are counted.
• Time precision. time_precision = exact records carry announced_at (decoded from the X post id). Date-only records carry announced_on and no timestamp; nothing is invented. utc_day is null when the evidence does not establish a UTC day.
• Counts and gaps. stats.total counts distinct qualifying events. avg_interval_days and longest_gap_days use only gaps between consecutive events with exact times on both sides, and a gap never bridges a date-only event. days_since_last is the unfinished time since the latest event and is never part of the longest gap.
• Filters. audience=max|pro|team match events whose stated audience includes the plan; "all users" and "all subscribers" count as including paid plans; unknown eligibility never matches. window=five_hour|weekly match named windows only. A filter is not a check of anyone's account.
• Corrections. Edited events keep their id and bump revision and revised_at. Retracted or cancelled events stay retrievable on their event page but leave the counted history; the feeds label them.
• Forecasts. None. active_watch is always null.
• Caching. Responses carry ETag and Cache-Control: public, max-age=60; send If-None-Match to get 304. Rate limiting returns 429 with Retry-After. Content problems return 503. Errors use application/problem+json.
• Metadata. meta.generated_at is when the response was built; meta.editorial_reviewed_at changes only after a manual source review; meta.content_revision changes whenever content is republished.

Feeds

The same published history is available as RSS and JSON Feed. Item ids are the stable event URLs; date_modified / atom:updated change on corrections.
