— WHY IS THIS NEEDED?
Heparin Sodium — unfractionated heparin for thrombosis prophylaxis:
• Activity Ratio: Key parameter distinguishing UFH from low molecular weight heparins. Anti-Xa to Anti-IIa ratio must be close to 1.0 (range 0.8–1.2). This ensures predictable anticoagulant effect.
• Protein: Heparin is derived from porcine intestinal mucosa. Residual protein is an allergen and strictly limited (≤0.1%).
• Sterility and Endotoxins: Absolute requirements for parenteral administration.
• Molecular Weight: Controlled via gel chromatography (indirectly reflected by activity profile here, but MWD is critical in full QC).
⚠️ CRITICAL:
• Anti-Factor Xa Activity: 140–160 IU/mg
• Anti-Factor IIa Activity: 140–160 IU/mg
• Xa/IIa Ratio: 0.8–1.2
• Protein Content: ≤ 0.1%
• Sterility: No growth
• Endotoxins: ≤ 1.0 EU/mg
• Heavy Metals: ≤ 10 ppm
• Appearance: Clear, colorless to slightly yellow
⚠️ Note: Utility places special emphasis on UFH specificity. Deviation in Xa/IIa ratio indicates improper fractionation or degradation, altering pharmacokinetics and safety profile. Protein control is critical to prevent anaphylactic reactions.

5. URS — user requirements

ID	Requirement	Criticality	Acceptance criterion
URS-001	The system shall accept an `input.csv` file for Heparin Sodium 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, 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.

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-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-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.
