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

+# Task 07 — Column Mapping (raw → canonical)
+
+## Goal
+For every `measurement_type × fingerprint`, a complete mapping of raw columns to canonical columns.
+
+## Input
+- `manifest/fingerprint_report.md`, `manifest/inconsistencies.csv`.
+- Target canonical schemas (ERD): `xrf_spectrum_points`, `nanoindentation_points`, `friction_data_points`, `macro_friction_points`.
+
+## Actions
+1. For each fingerprint create `config/column_mappings/<type>__<fingerprint>.json`: `{raw_name|position → canonical_name, unit_in, unit_out, dtype, transform(optional)}`.
+2. Resolve synonyms, reordering, unit variants; record every decision inline as `"note"`.
+3. Columns with no canonical target → escalate to Task 08 (ontology change) instead of dropping silently.
+4. `macro_friction_points` schema is PROVISIONAL — finalize from an actual macro-friction file profile here; propagate to Task 08.
+
+## Intermediate Result (done when)
+- Every fingerprint has a mapping file; no raw column is unmapped or undocumented.
+- Escalation list for Task 08 written to `schema/ontology_escalations.md`.
