Both fields MUST be updated together. Updating only one causes silent drift.

Waiver field: waber (Bengali transliteration of "waiver"). Do NOT rename.

Waiver purpose: waber_purpose. Do NOT rename.

Receipt chain: invoice → invoice_child → payment_receipt. Never break the chain.

Cash status: cash_status transitions are protected.

Protected

ALL waiver and receipt code requires [BIZ-QC-NEEDED] in commit body.

Do NOT

Rename waber or waber_purpose
Update total without updating on_net_total
Touch cash_status transitions without BIZ-QC approval
Query invoices directly from Blade views

Example

User: /fee-module Claude: Fee module context loaded. Protected: waiver calculation, receipt chain, cash_status. I will flag [BIZ-QC-NEEDED] on any commit touching these.
