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

+# 06 - Convert to PostgreSQL (indexed + partitioned)
+
+## Context / Goal
+Build the production-grade relational variant: the system-of-record candidate per the existing Storage ADR (PostgreSQL primary, RDF as deferred virtual layer).
+
+## Dependencies
+03.
+
+## Input
+CSV tree.
+
+## Processing instructions
+- Local PostgreSQL 16, database `tribo`. Same logical schema as task 05 with PostgreSQL types (`INT`, `REAL`, `TIMESTAMPTZ`, `TEXT`).
+- `friction_cycles` and `friction_loop_points`: declarative RANGE partitioning by `track_id` (12 partitions of 120 tracks) - models the partitioning strategy needed at 600 GB scale.
+- Load via `COPY FROM STDIN` (psycopg3 `copy`), not INSERT.
+- Indexes after load: PK b-trees; `tracks(environment, load_mn)`, `coupons(au_wtpct_mean)`, `nanoindentation(coupon_id)`, BRIN on `friction_cycles(cycle)` per partition.
+- `track_summary` as a materialized view (`cof_ss_mean` = avg of cycles > run_in threshold; `run_in_cycles` via first cycle where |cof - cof_ss| < 2σ).
+- `VACUUM ANALYZE` after load. Record `pg_total_relation_size` per table and total into `storage_sizes.csv`.
+- Also export a compressed dump `./out/pg/tribo.dump` (pg_dump -Fc) for archiving-format comparison.
+
+## Output
+- Live `tribo` database + `./out/pg/tribo.dump`.
+- Marker `./out/.done/06.ok`.
