Produce a worker-health report with: asOf (UTC ISO at fetch time); uniqueSeats (dedupe by tokenId); onlineCount defined clearly as seats where working==true OR lastHeartbeatAt within the last 15 minutes of asOf (state which rule you used); daemonVersion histogram (version string -> count of unique seats); stale list = tokenIds whose lastHeartbeatAt is older than 2 hours before asOf (or missing heartbeat); seats on versions other than the mode/majority build (list those tokenIds + their version).

Deliverables: WORKER_HEALTH.md (readable summary matching the numbers) and WORKER_HEALTH.json (structured: asOf, uniqueSeats, onlineCount, onlineRule, daemonVersionHistogram, staleTokenIds, nonModeVersionSeats[{tokenId,daemonVersion}]). Do not invent ids; if /workers is a live snapshot not a historical archive, state that caveat. Success = JSON parses, sum of histogram counts equals uniqueSeats, and MD totals match JSON.

Worker health report

  • asOf (UTC, fetch time): 2026-09-25T05:50:24Z
  • Source: GET https://api.imd.fun/workers — raw response saved at data/workers-snapshot.json (HTTP 200, server date: Fri, 25 Sep 2026 05:50:24 GMT, 384031 bytes)
  • Caveat: GET /workers is a live point-in-time snapshot of currently registered daemons, not a historical archive; seats that are disconnected may be absent entirely rather than listed as stale.
  • Structured twin: WORKER_HEALTH.json (every number below is copied from it).

Online rule used: online = working is truthy (the API returns an integer; treated as working when > 0) OR lastHeartbeatAt is within the 15 minutes before asOf (asOf - 15m <= lastHeartbeatAt, future timestamps also count as fresh).
Breakdown: 1 seat(s) have working > 0; 342 seat(s) have a heartbeat inside the 15-minute window.
Stale rule used: stale = lastHeartbeatAt missing/unparseable OR lastHeartbeatAt < asOf - 2h.

None. Oldest heartbeat in the snapshot is 2026-09-25T05:50:05Z, newest 2026-09-25T05:50:24Z — all within seconds of asOf.

Facts, inferences, uncertainty

Facts (read directly from the snapshot):

  • The response had count: 342 and 342 worker records; 0 lacked a tokenId and 0 repeated an already-seen tokenId, giving 342 unique seats.
  • Seat(s) with working > 0: 1943.
  • Heartbeats range from 2026-09-25T05:50:05Z to 2026-09-25T05:50:24Z.

Inferences (not stated by the API):

  • working is returned as an integer (0/1 in this snapshot), not a boolean; it is read as "currently running a job" and treated as true when > 0.
  • Every record reports connectedHere: true and a heartbeat seconds old, which suggests the endpoint lists only currently connected daemons. If so, the stale list is structurally near-empty: a seat that went offline is dropped rather than shown with an old heartbeat, and offline seats cannot be counted from this endpoint.
  • The earliest connectedAt in the snapshot is 2026-09-25T04:46:29Z, so the connection set may have been reset (e.g. server restart) around then; the snapshot says nothing about earlier periods.
  • The "mode build" is the single most common daemonVersion string; the build suffix (e.g. +5bfa8261) looks like a git short hash, but whether it is newer or older than the other builds cannot be determined from this data.

Uncertainty / unanswered questions:

  • This is one point-in-time read; numbers will differ on the next fetch. No history or trend is available.
  • The total number of seats that exist (including offline ones) is not answerable from /workers.
  • Server-side semantics of lastHeartbeatAt, working, and connectedHere are undocumented here; the rules above are this report's definitions.

    The worker-health report is done: I fetched a live snapshot from GET https://api.imd.fun/workers at asOf 2026-09-25T05:50:24Z (HTTP 200) and built the report from it.

    MetricValue
    Unique seats (deduped by tokenId)342 (342 records, no duplicates, none missing a tokenId)
    Online342
    Stale (heartbeat older than 2h, or missing)0. Every heartbeat is between 05:50:05Z and 05:50:24Z.

    Seats not on the majority build (+5bfa8261)29, each listed with its tokenId and version

    Online rule: a seat counts as online if working > 0 or its lastHeartbeatAt is within the 15 minutes before asOf. The API sends working as a number (0 or 1), not true/false. Only one seat (tokenId 1943) had working > 0; all 342 were online because of their heartbeats.

    Caveats, stated in the report:

    • /workers is a live snapshot, not a historical archive.
    • Every record shows connectedHere: true and a heartbeat seconds old. That suggests the endpoint only lists currently connected daemons. If so, the stale list will almost always be empty, because offline seats drop out of the list rather than showing an old heartbeat. This is an inference.
    • The earliest connectedAt is 04:46:29Z, so the connections may have been reset (for example by a server restart) around then.
    • Unanswered: the total number of seats including offline ones, and whether the builds are newer or older than each other.

    The report separates facts, inferences and unanswered questions under their own headings.

    Checks: I ran these locally and they all passed:

    • The JSON parses.
    • The histogram sums to uniqueSeats.
    • The markdown totals, histogram rows and the 29-seat list match the JSON exactly.
    • Every tokenId and version in the report appears in the raw response.

    The verifier only checks files, and nobody else has reviewed the numbers.

    Files:

    • WORKER_HEALTH.md and WORKER_HEALTH.json: the deliverables.
    • WORKER_HEALTH_README.md: the question and the limits.
    • data/workers-snapshot.json: the unmodified API response, with fetch details in data/workers-snapshot.meta.json.
    • scripts/worker_health.py: the generator. --as-of 2026-09-25T05:50:24Z rebuilds the report offline from the saved response; --fetch takes a new snapshot.

    These are committed as 9dd0b60. Git had no user name or email set, so I set your email as author and committer for that one commit only. I didn't change the git config.

    artifacts/report.md is a copy of WORKER_HEALTH.md. It's untracked, as required: the repo already excludes artifacts/ from git, which is why the committed files are at the top level instead.
