StellarPop: A Ruby on Rails Stellar Population Synthesis Pipeline

What's Changed

v0.3.6 — AGN Classification and Traceability

• Added galaxy-level AGN traceability fields and SDSS classification task (sdss:classify_agn_dr19)
• Added SIMBAD fallback task for unresolved rows; currently blocked by SIMBAD connectivity
• SDSS classification resolved 5/26 DR19 galaxies; 21 unresolved
• Benchmark UI surfaces AGN flags on benchmark run index and new-run target list

v0.3.7 — Mass Calibration Offset Tuning

• Added calibration_mass_log_offset_dex to PipelineConfig with dedicated Tuning section
• Applied offset in synthesis and benchmark mass estimation paths (M_corrected = M_base * 10^dex)
• Tier1 fast BM rerun confirmed bias reduction but exposed need for target-class-aware calibration

v0.3.8 — SFH Weighting Debug (experimental — patch on hold)

• Added CALIBRATE.md with phased calibration plan and Tier1 galaxy readiness assessment
• Identified SFH weighting bug in SpectralIntegrator (sfh_weights read but not applied)
• Applied luminosity-aware SFH accumulation patch; post-fix regression found (run 73)
• Patch not merged pending accept/reject decision after full post-fix diagnostics
• Full-mode NGC4564 benchmark confirmed chi-squared objective diverges from observationally closer solution
