Evidence Narrative
Mixed evidence with cautious interpretation
The Gaussian bump comparator fit the r-band detections cleanly within the reported errors. The variability texture comparator found changes that are comparable to the reported photometric errors. Together, these favor a simple one-bump description over repeated or irregular texture in the current r-band detections. Coverage appears sparse or uneven, so cadence may affect the comparison.

Standard feature summarycomputed
Descriptive light-curve features were computed from 8 usable r-band point(s) for comparison across objects.
Template-family probelimited
Template-family probing was limited because required context such as redshift is unavailable.
Cross-survey contextnot_requested
External catalog context was not requested for this case-file run.
What Argus Can Say
Standard descriptive features are available for comparison across objects.
No spectroscopic information is recorded in this case file.
What Argus Cannot Say
Argus does not identify the object type.
Argus does not certify that the source is unusual.
Argus does not treat broker or catalog labels as ground truth.
Argus does not treat template-family probes as object identity.
Recommended Next Checks
Add verified redshift or context before interpreting template-family probes.
Run cross-survey context if network access and optional dependencies are available.
Inspect forced photometry around recent detections if available.
Caveat: This narrative summarizes evidence layers. It is not a physical classification.

Interpretation
Descriptive light-curve features were computed for r-band detections using the light-curve package. The r-band observed brightness range is moderate (0.37 mag). Standardized scatter is moderate for this detection set (0.11 mag). These features support comparison across objects. The maximum_slope value is cadence-sensitive for this object and should be read with the feature quality notes.
Caveat
Feature values are descriptive summaries only and do not identify the object type.
Evidence Triage Assessment
anomaly_assessment is an evidence triage summary inside this case file. It summarizes available signals for review; it is not an object-identity claim.

Drivers
10 detections provide a usable local record.
Coverage spans 2917 days, enough to inspect long-baseline behavior.
Both g and r observations are present for cross-band review.
Standard descriptive light-curve features were computed.
Tensor mask diagnostics are available (87% bins masked).
Cautions
maximum_slope is cadence-sensitive: the steepest adjacent pair is separated by 3.6 minute(s). Treat this as a sampling diagnostic, not a robust physical rate.
Minimum adjacent detection spacing is 3.6 minute(s).
Template-family probe is limited: missing_required_context.
Catalog-context status is not_requested; external context remains limited.

Caveat: This deterministic assessment supports review triage only. It is not a classification, model verdict, or claim about physical identity.
Comparison Summary
Mostly consistent with a single smooth bump
The Gaussian bump comparator fit the r-band detections cleanly within the reported errors. The variability texture comparator found changes that are comparable to the reported photometric errors. Together, these favor a simple one-bump description over repeated or irregular texture in the current r-band detections. Coverage appears sparse or uneven, so cadence may affect the comparison.
Caveat
This is not a physical classification. It does not identify the object type, physical cause, or special status.
Recommended next check
Inspect residuals and verify that the pattern persists with additional local photometry.

Residual Summary
Residuals are concentrated in the most recent portion of the light curve.
The fitted peak time falls in a region with fewer than two nearby detections; peak placement is loosely constrained.
Coverage is highly uneven (largest gap 1282 days vs median gap 44.89 days); fit quality is limited by sparse coverage.
Residual scatter (σ ≈ 0.11 mag) is comparable to the fitted bump amplitude (-0.18 mag) — the data is not well described by a single bump.
Interpretation
A single Gaussian bump was fit to the r-band detections. RMSE = 0.11 mag, reduced χ² ≈ 0.4 — the bump shape is consistent with the data within the reported errors. See residual_summary for where the fit fails.
After 3-point smoothing, counted 1 local extrema/sign change(s).
Robust scatter is comparable to the reported errors.
Interpretation
The r-band detections (8 point(s)) span 0.37 mag with robust scatter 0.09 mag. After 3-point smoothing, 1 local extrema/sign change(s) were counted. The scatter is comparable to the reported photometric errors. The measured changes are small relative to the reported errors, so this check treats the sequence as measurement-level or nearly flat. This is descriptive only: it does not identify an object type, physical cause, or special status.

Uncertainty and Recommended Next Checks
Evidence Notes
Object has 10 rb-filtered detection(s) and 212 non-detection(s) on file.
Filters observed: g, r.
Coverage spans MJD 58263.42 to 61180.47 (2917 days).
Most recent detection: MJD 61180.47.
Longest gap between consecutive detections: 1282 days.
In g-band: 0 detections and 78 non-detection(s). Source was below detection threshold whenever ZTF looked in g.
No external classification label is attached to this object in local data.
Uncertainty Notes
Cross-survey catalog context is tracked in the cross_survey_context field; default offline runs record not_requested unless the optional lookup is explicitly enabled.
No spectroscopic information is on file.
No forced-photometry follow-up has been requested.
Candidate explanations above are placeholders, not fits, so mismatch magnitudes and goodness-of-fit values are not yet available.
No external classification label is present in local data.
Recommended Next Checks
Run the optional cross-survey context check at RA=284.45227, Dec=9.60622 if network access and optional dependencies are available.
Inspect archival image cutouts at this position and record any nearby source context as external metadata.
Pull ZTF forced photometry in a plus/minus 90-day window around the most recent detection (MJD 61180.47).
Add richer comparator families only when the required context is available, and record their residuals without treating them as object identity.
If the source is still active (last detection within ~60 days), request follow-up spectroscopy.
