https://arxiv.org/abs/2503.12244 CV-QPINN consistency-loss reproduction of Panichi et al. on the 1D Poisson and heat equations: pure-PyTorch Fock-truncated CV simulator, matched classical PINN baselines, 5-seed heat sweep, nested-vs- consistency ablation, and a MerLin linear-optics adaptation.

MerLin layer uses the 0.4 API (MeasurementStrategy.probs factory); re-running poisson_merlin under 0.4.0 reproduces the 0.3.2 RMSE (2.3728e-4 vs 2.3727e-4). Includes merlin_pinn unit tests and a ruff-clean pass over the paper directory.

results/ (tracked) now holds only compact curated artefacts; outdir/
(gitignored) keeps full raw run artefacts. New utils/curate_results.py
is the single supported promotion path (tested); aggregate_seeds.py
gains a compact results/seed_aggregate.json, epoch-aware grouping, and
per-group seed de-duplication. Removed raw prediction arrays, per-seed
JSON copies, and duplicate outputs from tracking; figures follow the
<label>.png convention. Also untrack session-handoff docs (LOG.md,
FEEDBACK.md, CONFLUENCE.md, INSIGHTS.md, VISITED_URLS.md) that were
swept into the previous commit by mistake — repo convention keeps them
local-only.
