# research_log — WP28 "distributed MLE: local bias correction vs. global synchronization"

## 2026-10-28
- 18:33 Mandate received (brief `CLAUDE.md`, 1,055 lines). Series inspected; template and WP 25/27 conventions noted (PROJECT_MAP.md).
- 18:36 Prior draft located in `~/Downloads/WP28_UQO_Claude_Research_Brief/`; frozen under `references/initial_pamle/` with SHA256.
- 18:39 Original Monte Carlo re-run: `python3 monte_carlo.py` in a scratch copy, seed 20261028 → max |Δ| = 7e-15 (summary),
  4.5e-13 (replicates). Old `pamle.tex` compiles (16 pp.).
- 18:45 Cluster inventory: 22 nodes reachable; default `python3` lacks NumPy on most minis → Phase 8 will provision a venv per node.
- 18:47 Four literature-verification tasks launched (ZDW/Huang–Huo/Lin–Xi/Rosenblatt–Nadler; CSL/CEASE/FONE/DANE/EDSL/Battey/
  Volgushev/Shang–Cheng; jackknife & bias-correction classics; 2013–2026 priority-threat sweep).
- Decision: identifier WP28 kept (see SOURCE_PROVENANCE.md collision note).
