Generate a construction draw workbook

Prerequisites

• A working Rust toolchain and a checkout of the workspace containing the accounting crates.
• A data directory with the shared entity/account/consolidation registry populated for the entity these reports run against, plus real budget-lock data from the sibling construction engine (see tool-construction — construction cost, schedule, and quality ledger).
• No services need to be running for any of the five binaries below.

Purpose

Produce the reporting package an equity investor's independent directors, or a construction lender where one exists, review during an active build: what's being requested against the project's approved budget, the statutory declaration required under construction-lien law, a record of payments actually disbursed, and a calendar of statutory payment due dates cascading from real invoice-receipt dates.

This guide is distinct from Generate a financial statement package, which covers a different, entity-level statement toolchain — this one is specific to an active construction project's own draw/capital-call cycle.

Procedure

1. Point every binary at the shared data directory

export TCO26_DATA_DIR=/data/construction/example-project

The same environment variable the construction-side reports use — this toolchain reads from the same data directory, not a separate one.

2. Run the reports

cargo run --bin capital_call_request -p tool-accounting-tco-26
cargo run --bin capital_call_schedule -p tool-accounting-tco-26
cargo run --bin statutory_declaration -p tool-accounting-tco-26
cargo run --bin checks_issued -p tool-accounting-tco-26
cargo run --bin cash_flow_calendar -p tool-accounting-tco-26

Each is independent — running one does not require having run any other first, and each writes its own HTML and PDF into <data-dir>/outputs/<year>/.

Expected outcome

Report	Real output
Capital call request	The current request to the entity's independent directors, sized against the real approved budget
Capital call schedule	The running Original Estimate / Revised Estimate / Costs Completed to Date / Cost to Complete / % Complete / Holdback register a capital call draws from
Statutory declaration	The sworn lien/holdback compliance attestation the underlying construction-lien statute requires
Checks issued	A disbursement register keyed off the real cash account — genuinely empty until a real payment has been disbursed
Cash-flow calendar	A calendar of owner-payment and subcontractor-payment due dates, each cascaded from a real invoice-received date

Verification

• Open each PDF and look at it.
• A genuinely empty register is not a defect. On a project with no real payroll, invoice, or payment ever posted, every one of these five reports correctly renders with real, honest zero balances or an empty table — not a fabricated figure. Read each report's own basis-of-preparation note before treating an empty result as broken.
• Confirm the capital call reports never use lender language (a "draw request" to a bank) if the entity you're running this against is equity-financed — the report's own framing follows the entity's real financing structure rather than defaulting to loan terminology.

What this task does not do

• It does not compute the statutory due-date cascade from anything other than a real, recorded invoice-received date. A blank invoice-received date produces no calendar entry for that transaction, not an estimated one.
• It does not disburse or authorize a payment. These reports read the ledger; nothing in this task writes a payment or a check.

Edge cases

• A project with no real transactions posted yet produces a complete, real set of five reports, all correctly showing empty balances — this is the expected state for a project at kick-off, not an error.

Rollback

Nothing to undo — every binary reads existing files and writes only into <data-dir>/outputs/<year>/.

Next steps

• Monitor an active construction project — the construction-side reports this workbook's figures ultimately trace back to
