Check the exact operation, source preservation and receiving format.
Name the operation precisely
Encoding, decoding, formatting and validating are different tasks. Base64 encoding represents bytes as text; it is not encryption. URL decoding interprets escape sequences; it does not fetch the destination. A formatter can adjust whitespace without proving that a programme or document is syntactically valid.
Keep a source fixture
Retain a short representative input and its expected output. Include quotation marks, non-ASCII text, line breaks and separators that matter to the receiving system. A regular expression literal containing a semicolon must remain intact when JavaScript is formatted. Compare meaningful characters before accepting a whitespace transformation.
Test the receiving contract
A well-formed XML document can still fail an XSD or application schema. JSON syntax alone does not verify required field names or business rules. A generated UTM address does not establish that analytics receives campaign data. Check the output in the target system and distinguish local processing from an external integration.
Separate estimates from exact counts
A rough English token estimate is not a model tokenizer. Billing, context limits and multilingual content need the provider’s exact convention. For usage costs, attach the rate-card date, billing scale, retries and free-tier treatment. Keep the original source and the verified result so another person can reproduce the check.
Review record
| Source | Convention | Result | Next check |
|---|---|---|---|
| Record the measured or supplied values. | State units, period and inclusions. | Retain the original calculation. | Name the person and evidence needed before use. |
