Purpose

Keep Field Studio a generic Akaunting module for defining, validating, storing and auditing custom fields, with no organization-specific configuration or historical migration logic bundled in its code.

Changes

• Remove the production-specific historical ETL script scripts/production-metadata.php.
• Remove the legacy free-text parser Domain/ProductionMetadataText.php and its dedicated tests.
• Remove the Produção Cooperativista migration procedures from docs/operations.md.
• Clarify the generic module boundary in README.md, docs/development.md, and AGENTS.md.

Company-specific field definitions, policies, discounts, normalization procedures and business rules are not shipped or versioned by Field Studio. Organizations configure their fields at runtime through its UI/API.

Data safety

This is source-code/documentation removal only. No database schema changes, no changes to custom field CRUD, no migration execution, and no deletion or update of stored definitions, values, audit rows, invoices or payments. The Field Studio's own generic database migrations remain intact. Existing installed runtime data is preserved. No production deployment is included.

Validation performed

• All remaining PHP files: php -l (PHP 8.4 container) — passed.
• php tests/i18n-check.php — passed (176 catalog strings; 136 references).
• node --check for all remaining JS tests — passed.
• module.json and composer.json parse — passed.
• git diff --check origin/main...HEAD — passed.
• Repository search for removed migration classes, marker, script, and cooperative-specific field keys — no occurrences.
• Signed commits with verified DCO.

End-to-end API/browser tests against an isolated Akaunting installation were not executed in this change. CI status must be evaluated at the final HEAD.

Scope exclusions

No alteration of the existing company-specific definitions and values in any installed instance; no changes to the separate #7 select-persistence fix; no migration or data cleanup on Conceição.
