- config.yaml: remove ambiguousorinvalidcolumn linter rule (false positives on read_csv TVFs)
- fct_cot_positioning: use TRY_CAST throughout — CFTC uses '.' as null in many columns
- raw/cot_disaggregated: add columns() declaration for 33 varchar cols
- dim_commodity: switch from SEED to FULL model with SQL VALUES to preserve leading zeros
Pandas auto-converts '083' → 83 even with varchar column declarations in SEED models
- seeds/dim_commodity.csv: correct cftc_commodity_code from '083731' (contract market code)
to '083' (3-digit CFTC commodity code); add CSV quoting
- test_cot_foundation.yaml: fix output key name, vars for time range, partial: true,
and correct cftc_commodity_code to '083'
- analytics.py: COFFEE_CFTC_CODE '083731' → '083' to match actual data
Result: serving.cot_positioning has 685 rows (2013-01-08 to 2026-02-17), 23/23 tests pass.

Remove distributed R2/Iceberg/SSH pipeline architecture in favor of
local subprocess execution with NVMe storage. Landing data backed up
to R2 via rclone timer.
- Strip Iceberg catalog, httpfs, boto3, paramiko, prefect, pyarrow
- Pipelines run via subprocess.run() with bounded timeouts
- Extract writes to {LANDING_DIR}/psd/{year}/{month}/{etag}.csv.gzip
- SQLMesh reads LANDING_DIR variable, writes to DUCKDB_PATH
- Delete unused provider stubs (ovh, scaleway, oracle)
- Add rclone systemd timer for R2 backup every 6h
- Update supervisor to run pipelines with env vars

- Update secret token: CLOUDFLARE_API_TOKEN → R2_ADMIN_API_TOKEN
- Update warehouse name: R2_WAREHOUSE_NAME → ICEBERG_WAREHOUSE_NAME
- Update endpoint: ICEBERG_REST_URI → ICEBERG_CATALOG_URI
- Remove CREATE SCHEMA and USE statements
- DuckDB has bug with Iceberg REST: missing Content-Type header
- Schema creation via SQL currently not supported
- Models will use fully-qualified table names instead
Successfully tested with real R2 credentials:
- Iceberg catalog attachment works ✓
- Plan dry-run executes ✓
- Only fails on missing source data (expected) ✓

- Add catalog ATTACH statement in before_all with SECRET parameter
- References r2_secret created by connection configuration
- Uses proper DuckDB ATTACH syntax per Cloudflare docs
- Single-line format to avoid Jinja parsing issues
- Remove manual CREATE SECRET from before_all hooks
- Secret automatically created by SQLMesh from connection config
- Cleaner separation: connection defines credentials, hooks use them
Successfully tested - config validates without warnings.
Only fails on missing env vars (expected locally).

- Move Iceberg secret from before_all hook to connection.secrets
- Fixes SQLMesh warning about unsupported @env_var syntax
- Uses Jinja templating {{ env_var() }} instead of @env_var()
- Remove database: ':memory:' (incompatible with catalogs)
- DuckDB doesn't allow both database and catalogs config
- Connection defaults to in-memory when no database specified
- Simplify before_all hooks to only handle ATTACH and schema setup
- Secret is now created automatically by SQLMesh
- Cleaner separation: connection config vs runtime setup

- Remove dev gateway (local DuckDB file no longer needed)
- Single prod gateway connects to R2 Iceberg catalog
- Use virtual environments for dev isolation (e.g., dev_<username>)
- Update CLAUDE.md with new workflow and environment strategy
- Create comprehensive transform/sqlmesh_materia/README.md
Benefits:
- Simpler configuration (one gateway instead of two)
- All environments use same R2 Iceberg catalog
- SQLMesh handles environment isolation automatically
- No need to maintain local 13GB materia_dev.db file
- before_all hooks only run for prod gateway (no conditional logic needed)
