# IC 443 agent log: every PixInsight call, 25 October 2026

The pixinsight-connector record of one supervised afternoon processing the Jellyfish Nebula (IC 443) in PixInsight, from 14:22:53 to 17:39:17 local time (IST). 651 calls in 522 rows, plus 15 decisions of mine.

- **#** is the connector call number. Runs of `job_status` polls on one background job are collapsed into one row; the poll count is in the Tool column.
- **Status:** ok (worked), rejected (ran fine, but the result was rejected on evidence; set on the check or preview that showed it), fail (real error), undone (rolled back on purpose), alarm (false "watcher stopped" report), decision (mine, not a tool call).
- **Time** is when the call returned. **s** is the time spent inside the call.
- Paths are relative to the project folder. The user name, machine identifier and drive letters have been removed.
- The scripts the agent wrote are in `scripts/`. The structured version of this table is `ic443-agent-log.json`.


## Preflight

|---|---|---|---|---|---|---|---|
| 1 | 14:22:53 | pixinsight_info |  | PixInsight 1.9.5 and ImageSolver located | ok | 0 | Preflight: find PixInsight and ImageSolver before anything runs |
| 2 | 14:22:53 | workspace_info |  | Workspace usable; state, scratch, bridge, log and output folders resolved under the project | ok | 0 | Confirm the workspace and the bridge, log and output folders the connector will use |

| 4 | 14:23:13 | inspect_environment | full probe | Gaia DR3/SP valid (18 files); MARS DR1 and DR2 readable; BXT, NXT, SXT 2.6.10 on GPU; 15.5 s | ok | 15.5 | Preflight: probe Gaia, MARS and the RC-Astro tools so the processing skills can refuse a broken setup |

## Intake

|  | 14:37 | decision | Agent asked: There is no L master. How should luminance be handled? | "Can we take HSO all for luminance?" | decision |  |  |
|  | 14:37 | decision | Agent asked: RGB filter brand, narrowband bandwidth and pixel scale? | Optolong 3nm (clarified next); 3 nm; 1.176″/px | decision |  |  |
