Nothing is queued: on the human's decision, 412541 (jax_cpu sparse) and 412565 (numba_cpu sparse) were cancelled ~15:51Z with partial stages left on disk (no CPU fixed-light row exists). 412535 and 412537 (A100) and 412539 (jax_cpu dense) completed; numba_cpu dense dropped. The project is on the flat layout (autolens_inference#36, c3ca4de; output/autolens/..., rows at results/slam/imaging/hst/&lt;variant&gt;/&lt;config&gt;/), and the wave-1 attempt-1 material is set aside. Next, each needing the human's go: confirm keeping prepared/; a Mind bug task and laptop repro for the jax_gpu sparse fixed-light mass_total[1] divergence; rerun the cancelled sparse remainder (jax_cpu sparse seed 1 from source_pix[2], the lightfixed mass_total[1] legs); GPU wave 1 attempt 2 (nautilus+emcee); commit the clean-slate rows in a project PR.

 This is the markdown version of the [PyAutoCortex Dashboard](https://pyautolabs.github.io/PyAutoCortex/), which puts the check-in and each project's resume prompt on your clipboard with a single tap of 📋.
 
 One ledger per science project: what is on the cluster right now, what the human said they would do next, and the last few things they wrote down. Nothing here is inferred from a result — the board hands you the check-in and the resume prompt; what a run meant is yours to log.

Next: pull the A100 dense rows and read them; wave 1 attempt 2 (nautilus and emcee) after the writer fix in the filed Mind task, NUTS and SMC deferred with the OOM evidence; then the CPU wave once the CPU dense base rows land.

+Clean slate on pin 2026.10.17.1, campaign hst-imaging-mass-samplers, state read 2026-10-19 15:49:05Z. Nothing is queued: on the human's decision, 412541 (jax_cpu sparse) and 412565 (numba_cpu sparse) were cancelled ~15:51Z with partial stages left on disk (no CPU fixed-light row exists). 412535 and 412537 (A100) and 412539 (jax_cpu dense) completed; numba_cpu dense dropped. The project is on the flat layout (autolens_inference#36, c3ca4de; output/autolens/..., rows at results/slam/imaging/hst/&lt;variant>/&lt;config>/), and the wave-1 attempt-1 material is set aside. Next, each needing the human's go: confirm keeping prepared/; a Mind bug task and laptop repro for the jax_gpu sparse fixed-light mass_total[1] divergence; rerun the cancelled sparse remainder (jax_cpu sparse seed 1 from source_pix[2], the lightfixed mass_total[1] legs); GPU wave 1 attempt 2 (nautilus+emcee); commit the clean-slate rows in a project PR.

GPU sampler wave 1 (412543) attempt 1 failed on every arm in two classes: a row-writer TypeError on tuple-keyed parameter names after the nautilus and emcee fits completed, and A100 out-of-memory for NUTS (385.32GiB) and SMC (48.45GiB); pending arms 18-23 cancelled at 19:40Z, arms 9, 13, 17 still running then. Next: pull the A100 dense rows and read them; wave 1 attempt 2 (nautilus and emcee) after the writer fix in the filed Mind task, NUTS and SMC deferred with the OOM evidence; then the CPU wave once the CPU dense base rows land.

+Clean slate on pin 2026.10.17.1, campaign hst-imaging-mass-samplers, state read 2026-10-19 15:49:05Z. Nothing is queued: on the human's decision, 412541 (jax_cpu sparse) and 412565 (numba_cpu sparse) were cancelled ~15:51Z with partial stages left on disk (no CPU fixed-light row exists). 412535 and 412537 (A100) and 412539 (jax_cpu dense) completed; numba_cpu dense dropped. The project is on the flat layout (autolens_inference#36, c3ca4de; output/autolens/..., rows at results/slam/imaging/hst/<variant>/<config>/), and the wave-1 attempt-1 material is set aside. Next, each needing the human's go: confirm keeping prepared/; a Mind bug task and laptop repro for the jax_gpu sparse fixed-light mass_total[1] divergence; rerun the cancelled sparse remainder (jax_cpu sparse seed 1 from source_pix[2], the lightfixed mass_total[1] legs); GPU wave 1 attempt 2 (nautilus+emcee); commit the clean-slate rows in a project PR. No scientific acceptance implied.

 - 2026-10-18 — note — HUMAN DECISION 2026-10-18, verbatim: "lets just drop dense numba we would never use it." The numba_cpu dense leg (RAL 412563, failed with pool-worker SIGSEGV) is dropped from hst-imaging-mass-samplers with no rerun; the campaign's CPU base is jax_cpu dense, jax_cpu sparse and numba_cpu sparse. Canonical record: https://github.com/PyAutoLabs/PyAutoInsight/blob/main/decisions/hst-cleanslate-drop-numba-dense.md (Insight commit e289c04 on PR #36).
 - 2026-10-18 — note — OBSERVATION awaiting the human's reading, not a conclusion (architect, 2026-10-18 ~16:55Z, rows read on RAL, pin 2026.10.17.1): the slam_base_lightfixed mass_total[1] stage on the jax_gpu SPARSE inversion (412537) lands on a wrong, sharply peaked solution on both seeds: max logL about -43 500 against about +31 649 for the linear mode; log Z -43567.1 / -43201.6; posterior pinned at slope 2.964+-0.0004 / 2.963+-0.0002, einstein_radius 2.493 / 2.427, gamma_1 0.0994 / 0.0998, ell_comps_0 0.59 / 0.57; truth_delta_sigma slope 2250 / 6275 (seed 0 einstein_radius 114, gamma_1 289); 48 700 evaluations at seed 0. The same stage on the jax_gpu DENSE inversion (412535) is the best-recovered row of the campaign (worst abs delta-sigma 0.24 / 0.34). Stages 1-4 are shared between the two light modes, so the difference is isolated to the fixed-light mass_total[1] under the sparse path. Possibly a library or driver fault in the sparse (w_tilde) inversion with ordinary (non-linear) lens light profiles rather than a sampler effect; a laptop reproduction on the exported prepared problem is proposed before any CPU or sampler wave uses the sparse fixed-light problem. Human reading pending.
