What we read from 300 public GitHub events across the last day. Real attribution preserved — these events are already public.

Jarred-Sumner is carrying 94% of the human writing work.

1 PR merged with no independent review. Spans 1 repo. Either reviewers were anonymous to the events feed, or the PRs went in without a non-author approval.

Jarred-Sumner is carrying 94% of the human writing work. 45 of 48 commit + PR-open + PR-merge events concentrated on a single human contributor. Bus-factor risk visible from the public feed.

@Jarred-Sumner

Jarred-Sumner authored 45/46 commits in oven-sh/bun. 98% concentration in this window. If Jarred-Sumner stops, oven-sh/bun stalls.

63% of writing this window was automated. robobun accounts for 75 of 80 bot events. The underlying human-engineering signal is sparse — interpret human-only stats with that in mind.

FIG 5  ·  Rituals we can't see from GitHub alone

Public-GitHub data shows code behaviour. The rituals below need the rest of the toolchain. With Slack, Linear, Notion and Google connected, Assemblr would also surface:

  • Silent merge · PR merged with no Slack/release-notes followup within 30 min.

    Needs: Slack #releases channel

  • Orphan ticket · Linear issue closed without a corresponding code merge in 7 days.

    Needs: Linear (or Jira) to see ticket transitions

  • Ladder break · Cross-toolkit ritual fires N-1 of N expected steps for ≥3 occurrences.

    Needs: Linear + Slack to stitch the cross-tool ladder

  • Stale-design code · Code shipped where the linked design doc hasn't been touched in 30+ days.

    Needs: Notion or Google Docs for design-doc edit history

  • Postmortem skip · Incident channel created, no postmortem doc within 7 days of resolution.

    Needs: Slack incident channels + Notion postmortem template

  • Phantom standup · Standup channel post pattern that ran ≥4 weeks then stopped ≥7 days ago.

    Needs: Slack standup-channel message stream

This is what we'd see for your team.

Connect GitHub, Slack, Linear, Notion, and Google. We mine the actual behavioural patterns and ship a weekly briefing your VPE will actually read.
