Authoritative source, reproduced unchanged. Exact Markdown · Agent copy with resolved links · The files: data/pixels-hourly/README-activity.md. These instructions govern research runs, not checkpoint interviews. They keep the run's own words: a room is a community, a mark an artwork, the analyst the aggregator, the case lead the community coder and the global model the population model.

One row per room of the frame: how active it was in the 168 hours before the canvas opened (2017-03-24 16:00 to 2017-03-31 16:00 UTC).

sub, posts_week_before, comments_week_before, distinct_posters_week_before,
first_record_utc, existed_before_window, founded_during_event

distinct_posters_week_before counts the accounts that posted or commented in the room that week, less [deleted], [removed] and AutoModerator. first_record_utc is the room's first item in the 24-day record; existed_before_window is 1 if that falls before the canvas opened; founded_during_event is 1 if the room's first item falls inside the event. A room with no poster that week has 0 there.

Counted from each room's full 24-day record (raw24) as collected in August 2026, the same record the coders' rooms were cut from, and the same scan whose author lists define px_by_pre_members in pixels.csv. It measures size before the event, not anything the room did on the canvas. Stage D4 uses it for the volume check: log(1 + distinct_posters_week_before).

Provenance by row (2026-10-04)

705 rooms. 690 rows come from the study's pre-window list (_pre_progress.jsonl, LINK.md; sha256 ee3f8eebbfaf427b9351457363256e01cb3dcfd1d2bf63903a1320e4f4fc743e): 679 that build_pixels.py --activity reproduces byte for byte from it; r/dota2, r/globaloffensive, r/leagueoflegends and r/overwatch, appended from it on 2026-10-02; and r/anime, r/DestinyTheGame, r/hearthstone, r/masseffect, r/pcmasterrace, r/rickandmorty and r/wow, appended from it on 2026-10-04 when they joined the frame. r/lehigh and r/upvote left the frame on 2026-10-04 and their rows with them. r/chelseafc and r/hyperlightdrifter were remade from their full records on 2026-09-27, and 13 communities added to the census on 2026-09-26 and 27 come from their raw24 lists (--lists-from-raw24).
