fix(docs): fix formatting issues in README.md

- adapt meta-/code-/obs- rules to the local Python benchmark pipeline
- replace db-sql-ddl, code-config-env-scope, test-e2e-pytest with pipeline equivalents
- add code-python-style, data-determinism, data-naming-units, bench-methodology, build-pipeline-tasks
- normalize specs and README typography to ASCII per code-data-formatting
- rewrite root CLAUDE.md trigger table; add .cursorrules and .gitignore
- specs: pipeline plan and task specs 00-11
- rules: 19 binding rule files adapted for this project
- docs: CLAUDE.md rule-trigger table
- config: .cursorrules commit convention, .gitignore excluding out/ and .venv/
- docs: rewrite README.md with pipeline diagrams, setup guide, result placeholders
- config: requirements.txt for the closed dependency list
- datagen: make_lab_config.py writes out/config/lab_config.yaml and .done marker

+# 02 - Process Flow Diagrams
+
+## Context / Goal
+Generate the comprehensive Mermaid documentation of the laboratory workflow (reconstructed from the 10 Miro slides) as standalone `.md` / `.mermaid` artifacts for the final report and for human review.
+
+## Dependencies
+01 (uses volumes/terminology from lab_config.yaml).
+
+## Task
+Produce `./out/report/process_flow.md` containing the following diagrams, each also saved as a separate `.mermaid` file in `./out/report/diagrams/`.
+
+### D1 - Coupon Assembly
+```mermaid
+flowchart LR
+    A([Ti-6Al-4V Base 10x10x3 mm]) --> B[Cleaning]
+    B --> B1([Rinsed in deionized water])
+    B1 --> B2([Sonicated in cleaning solution])
+    B --> C[Smearing Adhesive]
+    C --> C1([Cr adhesive coating])
+    C --> D[Vapor Deposition System<br/>Kurt J. Lesker PVD 200]
+    D --> D1([PtAu sputter coating, gradient])
+    D --> E([Test Coupon])
+```
+
+### D2 - Characterization & Batch Assembly
+Test Coupon → SIMTRA (composition / atom energies) → Optical profilometry (film thickness 0.3-1.1 µm) → assemble Test Wafer (×49 coupons) → assemble Test Batch (×3 wafers) → batches 721-724 with the deposition parameter table.
+
+### D3 - Testing tree
+Friction (RAPID; Lab Air → µ_normal; Dry N2 → µ_dry_nit), Nanoindentation (TI980 → hardness, reduced modulus), AFM (topography → Ra), XRF (M4 Tornado → Pt/Au map).
+
+### D4 - Tribometer session sequence (sequenceDiagram)
+Request test → Get samples → Load samples → Load ball holders (3 counterfaces/holder) → Create Excel test plan (Sample Plate, Plate Location, Sample ID, Save Location, Folder Name, X/Y/Z Offset, Load, Iterations) → Transfer to tribometer → Set up platter → Activate software → Load plan → Activate tribometer → ... → Software stop → Save avg files → Remove plates/platters → Close software → Pull equipment out.
+
+### D5 - Execution loop (flowchart)
+```
+Load all counter-faces
+  FOR EACH of 5 plates
+    FOR EACH of 6 probes (parallel)
+      FOR EACH of 4 coupons on coupon square
+        3x per coupon: draw track -> rotate counter-face
+```
+
+### D6 - Data hierarchy ERD-style
+batch → wafer → coupon → {xrf_map, nanoindentation, afm, profilometry} and coupon → track → {cycles, loops, wear}; deposition → simtra_profile.
+
+## Output
+- `./out/report/process_flow.md`, `./out/report/diagrams/D1..D6.mermaid`
+- Marker `./out/.done/02.ok`.
