Normalize long-form CODEX cycle folders to short form before notebooks run. Trigger: cyc001_reg001_*, hard-coded cyc paths breaking, staged CODEX raw data failing in Notebooks 1/2.
v5.6.0 joint multi-TF model: single model per symbol with broadcast 1Hour context replaces dual 15Min/1Hour models. Trigger: (1) replacing weighted-voting model aggregation, (2) adding broadcast features to vectorized env, (3) limited training data + worried about overfitting from doubling obs_dim, (4) backtest builder mismatch with newer feature counts.
DEPRECATED in v5.6.0 — see joint-multi-tf-v560 skill. Documents the v5.2.0 dual-model approach (train separate 15Min/1Hour models, combine via weighted voting). Still relevant for: (1) loading legacy v5.5.0 dual models, (2) understanding the historical aggregation layer, (3) resampling pattern via origin='start'.
Surface a shipped-but-undocumented CLI feature in user-facing docs. Trigger: user reports a known feature missing from README/readthedocs even though the CLI command exists.
KINTSUGI Snakefile + CLI changes that route SLURM jobs around accounts saturated by OTHER users on the same QOS pool. Trigger: QOSGrpMemLimit, jobs stuck pending despite available GPU slots in config, noisy neighbor on shared QOS, multi-user investment pool exhaustion, _build_cycle_assignment static-vs-live.
KINTSUGI SLURM batch processing: Maximize throughput using multi-account resource calculation with GPU+CPU pools per account. Trigger: SLURM job submission, batch processing, resource maximization, GPU+CPU concurrent, headless processing, resource pool.

| Goal | Convert HiperGator signal-isolated channel TIFs into pyramidal OME-TIFF for QuPath |
| Environment | Python 3.12, tifffile, numpy; Linux |
| Status | Success |
HiperGator CODEX/Phenocycler processing outputs individual TIF files per channel (after signal isolation). These need to be consolidated into a single pyramidal OME-TIFF with proper metadata to be opened in QuPath v0.6.0 for downstream analysis.

# MUST use XML entity µ for µ — tifffile requires 7-bit ASCII
xml = f'''...PhysicalSizeXUnit="µm"...'''
| Attempt | Why it Failed | Lesson Learned |
|---|---|---|
Using Unicode µm in OME-XML | ValueError: TIFF strings must be 7-bit ASCII — tifffile encodes description tag as ASCII | Use XML numeric entity µm instead of Unicode µ |
Not setting metadata=None on first page | tifffile adds its own metadata conflicting with OME-XML | Always pass metadata=None when providing custom description |
