— WHY IS THIS NEEDED?
Canagliflozin — SGLT2 inhibitor for type 2 diabetes treatment:
• Structure contains a thiophene ring. Thiophene-containing impurities are strictly controlled (≤0.1%) due to potential genotoxicity risk.
• Synthesis may involve toluene and acetonitrile (ICH Q3C Class 2).
• Drug has low water solubility at neutral pH, so dissolution profile is critical for ensuring stable bioavailability.
• Drug taken long-term, so heavy metal and residual solvent requirements are stricter than usual.
⚠️ CRITICAL:
• Assay: 98–102%
• Melting Point: 220–225°C (with decomposition)
• Thiophene Impurity: ≤ 0.1% (strict genotoxicity limit)
• Isomer Impurity: ≤ 0.2%
• Total Impurities: ≤ 0.5%
• Toluene: ≤ 890 ppm
• Acetonitrile: ≤ 410 ppm
• Heavy Metals: ≤ 10 ppm
• Dissolution: ≥ 80% in 30 min, ≥ 85% in 60 min
• Microbiology: standard limits
⚠️ Note: Utility adapted for dissolution profile check. If dissolution data absent (0), check skipped (for substance). For finished forms, deviation from dissolution profile is critical defect. Thiophene impurity control is priority due to safety risks associated with heterocyclic impurities.

5. URS — user requirements

ID	Requirement	Criticality	Acceptance criterion
URS-001	The system shall accept an `input.csv` file for Canagliflozin with the exact columns listed in the “Input data contract” section.	High	A file with the correct header is processed without manual editing; missing mandatory columns produce FAIL/import error.
URS-002	The system shall support execution without arguments in demo mode and execution with `input.csv output.json` for user data.	Medium	Both execution scenarios produce a predictable result or clear diagnostic error.
URS-003	The system shall perform rule-based controls for: assay / content, purity and impurities, dissolution / disintegration, residual solvents, microbiology and pathogens, heavy metals / elemental impurities, pH and physicochemical parameters.	High	Each controlled parameter receives a status and message; the result does not depend on hidden Excel formulas or ML.
URS-004	The system shall preserve traceability between batch/lot, source values, applied rules and final verdict.	High	Output includes batch identifier, source values, parameter statuses and critical findings.
URS-005	The system shall generate machine-readable `output.json` for LIMS/ELN/MES, batch record and QA/QC review.	High	JSON contains overall status, check array, warnings, failures and source-file reference.
URS-006	The system shall support use in the client validation package: URS/FS, IQ/OQ preparation, installation and operational scenario checks.	High	The document, test scenarios and reproducible CSV/JSON flow are suitable for audit and internal approval.
URS-007	The system shall clearly separate technical data errors from specification nonconformities.	Medium	Schema/type errors are not mixed with pharmacopoeial deviations and are reported separately.

9. OQ/PQ test scenarios

ID	Scenario	Expected result
TC-001	Valid CSV with expected header and sample row	All rows are processed; output contains PASS/WARNING/FAIL and parameter-level detail.
TC-002	A mandatory input.csv column is missing	Import is rejected or the row receives FAIL with schema reference.
TC-003	A numeric field contains text or a blank value	Type conversion error is recorded; the result is not hidden as PASS.
TC-004	A parameter is outside specification or critical limit	Critical parameters produce FAIL; non-critical deviations produce WARNING according to the rule.
TC-005	Positive pathogen/microbiological flag or microbiological limit excursion	Critical FAIL is produced with the offending parameter.
TC-006	Insufficient dissolution or excessive disintegration time	FAIL/WARNING is produced according to method criticality.
TC-007	Residual solvent above applicable limit	FAIL is produced with solvent name and measured value.

10. QA/QC, CSV and change control

Before production use, the client records executable version, checksum, specification/monograph version, test CSV, expected JSON and IQ/OQ results.
Column names must not be changed without updating the validator and test scenarios.
The source CSV, output.json and utility version should be stored together as an evidence package.
Any change in control rules must go through change control and repeated OQ scenario verification.
