larsandClaude Sonnet 5	b944bba8fb	Offset event_id per file to avoid cross-file collisions ... Each input parquet file is one Geant4 job (scripts/steps_to_parquet.py), and a job's event_id numbering always restarts from 0 — so loading multiple files together (a directory or .manifest) let same-numbered events from different files collapse into one during the event index scan and train/val split, corrupting both. Every per-file event_id now gets offset by file index * EVENT_ID_FILE_STRIDE (giant/data/loader.py), threaded through the setup-cache event index, the streaming dataset, and predict/rollout seeding. Bumps the setup-cache format version so stale sidecars computed pre-fix are invalidated. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>	2026-07-30 11:36:48 +02:00
larsandClaude Sonnet 5	47a6c9db1f	Add regression coverage for vocab/process index-map builders ... build_index_maps, build_index_maps_from_files, and (mostly) build_process_map_from_files had no test pinning their sort order, tie-breaking, or cross-file union behavior — all load-bearing for a trained checkpoint's vocabulary, and all at risk of silently changing under a future single-pass (pyarrow/polars) rewrite of the setup-stage scan. Add tests for numeric-vs-lexicographic PDG sort (nuclear/ion codes), negative PDG codes, dedup/bijective indices, file-order independence, and process-map tie-breaking/boundary conditions (n_experts=1, fewer processes than experts, 3-file partial overlap).

lars	05d5dee606	Apply ruff format after merging phase2-secondary-prediction ... The merged proc_idx/proc_map plumbing wasn't run through ruff format before merging; reflow only, no logic changes.	2026-07-15 10:00:36 +02:00
lars	0b3ece52ed	Add ProcessRouter for physics-process-based expert gating ... Routes on the physics process (Compton, phot, brems, ...) that ends a step, supervised by a small classifier since process is a post-step outcome unobservable at gate time. Threads a process label end-to-end through the data pipeline (loader, build_features, dataset batches, training loss/checkpointing) alongside the existing EnergyRouter.	2026-07-08 16:15:09 +02:00
larsandClaude Sonnet 4.6	320365606a	Add tooling for a versioned geant_steps dataset layout ... Introduces raw/<kind>/<gen>/<detector>/shard-NNN.root and processed/<kind>/<gen>/<schema>/<detector>/shard-NNN.parquet as the dataset convention, plus scripts to operate on it: migrate_geant_steps.py for the one-time move into this layout, bump_dataset_version.py to cut new gen/schema versions with a logged reason, steps_to_parquet_parallel.py to convert ROOT shards to parquet in parallel and place them correctly, and create_root_files.py to generate new ROOT shards via a minicalosim executable. The loader gains .manifest file support so pools/ (train/dev/ holdout shard lists) can be passed straight to `giant train`.
