ℹ️ Does not use machine learning — rule-based logic only.
⚠️ CRITICAL! PAP ≤0.005%. Uniformity RSD ≤6.0%. Dissolution ≥80%!

— WHY IS THIS NEEDED?
Hydrocodone + Acetaminophen combination — strong analgesic:
• Hydrocodone is an opioid, requires strict content and uniformity control (low dose)
• Acetaminophen has toxic impurity PAP (p-aminophenol), limit is extremely strict (0.005%)
• Hydrocodone has specific synthesis impurities (thebaine, codeine)
• Synchronous dissolution of both components critical for analgesic effect
• Content Uniformity (CU) critical due to small hydrocodone dose in tablet
⚠️ CRITICAL:
• Content of both APIs: 95–105%
• PAP (Acetaminophen): ≤ 0.005% (toxicity)
• Thebaine/Codeine (Hydrocodone): ≤ 0.2% each
• Uniformity (RSD): ≤ 6.0%
• Dissolution: ≥ 80% in 30 min for both components
• Microbiology: absence of pathogens
⚠️ Note: Utility focuses on safety of opioid component and toxicity of paracetamol impurities. PAP exceedance unacceptable due to risk of liver and blood damage. Low hydrocodone uniformity may lead to lack of effect or overdose.

TC-001Valid CSV with expected header and sample rowAll rows are processed; output contains PASS/WARNING/FAIL and parameter-level detail.
TC-002A mandatory input.csv column is missingImport is rejected or the row receives FAIL with schema reference.
TC-003A numeric field contains text or a blank valueType conversion error is recorded; the result is not hidden as PASS.
TC-004A parameter is outside specification or critical limitCritical parameters produce FAIL; non-critical deviations produce WARNING according to the rule.
TC-005Positive pathogen/microbiological flag or microbiological limit excursionCritical FAIL is produced with the offending parameter.
TC-006Insufficient dissolution or excessive disintegration timeFAIL/WARNING is produced according to method criticality.

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.
