2026-02-20 21:08 - T-009

Overview: Added CLI entry point for entity/period/unit report generation.

Completed:

• feat(format): implement CLI arg parsing for --entity, --period, and --unit
• feat(format): wire CLI execution to assembleReport() and success/error logging

Files:

2026-02-20 21:09 - T-010

Overview: Installed dependencies and verified type-check for the new Format package.

Completed:

• chore(*): run bun install and update lockfile
• test(format): pass bun run test:type --filter @packages/format

Files:

• bun.lock

2026-02-20 21:09 - T-011

Overview: Attempted end-to-end format run; verification is blocked by missing marts in local DuckDB.

Completed:

• test(format): run bun run format --entity IONS --period 2026-02

Blockers:

• mart_revenue table does not exist in local atlas.db, so end-to-end verification cannot complete yet.

2026-02-20 21:12 - Amendment

Overview: Adjusted DuckDB binding strategy after runtime crash in Bun.

Changes:

• requirement: replaced duckdb-async usage with @duckdb/node-api in the format package implementation
• task: kept T-003 scope intact (typed query helper + closeable client), but implemented on stable bindings

Rationale:

• duckdb-async produced a Bun process crash (SIGTRAP) after report generation, preventing reliable CLI exits
• @duckdb/node-api is already used successfully in this repo (@packages/sync) and exits cleanly in Bun

2026-02-20 21:13 - T-011

Overview: Re-ran end-to-end verification after binding/path fixes and completed all acceptance checks.

Completed:

• fix(format): resolve DuckDB path against project root to avoid package-local empty DB creation
• refactor(format): switch client implementation to @duckdb/node-api for Bun runtime stability
• test(format): pass bun run format --entity IONS --period 2026-02 and validate report contents

Learnings:

• bun run --filter <pkg> executes in package context, so DB paths must be root-aware.
• Old DuckDB bindings can crash Bun on process teardown even after successful query execution.
