Merged pull requests across the public polarizetech repositories, newest first, synced from GitHub once a day. Every repository, with the posts about it, is under Work.

Findings, pre-release review, lint and MIT licence

  • docs/FINDINGS.md: every result across the project, and the project marked paused.
  • docs/REVIEW.md: three independent code and methods reviews; dated corrections appended to the affected reports (nothing rewritten).
  • ruff (correctness rules only) + lint workflow; the private-tool imports degrade loudly; MIT licence; public README.
  • Test suite: 100 passed. No numerical change to any committed run.

E01-stentor-map: Stentor-mapped habituation constraints (SR1–SR3) on the depression cascade

Preregistered experiment. See experiments/E01-stentor-map/PREREG.md and RESULTS.md.

Closed: FAIL (E01-stentor-map-closed, f10f688). 90 runs, 0 failed, model-v0.1.0.

  pre-registered (efficacy) observed (spikes) verdict
SR1-std: decrement deepens as recovery slows 0.126 → 0.494 → 0.624 → 0.728 0.057 → 0.418 → 0.597 → 0.765 PASS
SR1-std: half-point later 4 → 6 → 6 → 7 4 → 5.5 → 8 → 8 PASS
SR1-hebb_only: predicted null no change D16 unchanged (≤ ±0.023); median half point 4 → 4.5 FAIL (half-point clause)
SR3-std: strong insert deepens −0.21 % / −0.33 % −0.69 % / −0.93 %, under MDE 3.5 % UNINTERPRETABLE (analyse.py: FAIL)
SR3-hebb_only deepening −0.74 % (under MDE) / −3.46 % [−5.92, −1.00] UNINTERPRETABLE (analyse.py: FAIL)
SR2: decrement–rate slope +28.7 / +19.8 dB/decade slow-rate decrement below the ±0.03 floor not computable
  • Stentor’s longer retention after a block: not reproduced by the depression cascade (0 at ×1 and ×0.25; control at the floor at ×0.1 and frozen). It appears only in hebb_only, on shrinking n.
  • No dishabituation in any arm.
  • Deviations #1–#4 are in DEVIATIONS.md; #4 was decided with the outcome known.
  • Exploratory (fast-forward vs direct gaps) is under exploratory/.
  • Next EID: RESULTS.md §8.
  • Merge with a merge commit, never a squash.

E02-local-negative-image: depletion's specificity map, B-vs-H removal, R&M receptor structure under a synthesis block

Preregistered experiment E02 (KIT Adaptive Preregistration). Design and the research behind it: docs/E02/RESEARCH.md; plan: experiments/E02-local-negative-image/PREREG.md. Runs against model-v0.2.0. Tag receipts are posted below as each tag is made.

Nothing runs until the operator approves the preregistration.
