## Tactile Dot Template Measurement Review

USD 9.00 per job.

Compare explicitly identified raised dots with a supplied tactile template, retaining missing/extra dots, coordinate errors, diameter differences and height differences. At most64expected and64measured dots. Dot identities and intended patterns are supplied; this does not translate text or infer Braille meaning. Calculations use supplied measurements and owner-defined tolerances only. No physical inspection, accessibility certification, clinical interpretation, structural approval or external system change is included. Use consistent units. Tolerance comparisons use the same twelve significant digits as the report. Integral report quantities must remain exactly representable; unsupported calculation profiles reject before checkout. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.

## Incremental JSON Text Sequence Codec

USD 1.00 per job.

Encode or incrementally decode supplied RFC7464 UTF8 record-separator bytes. Records keep their original JSON text, avoiding numeric preview rounding. Invalid completed records are reported and parsing resumes at the next separator. Use final only at end-of-input; prepend pendingHex and resume with nextByteOffset. At most16384bytes/128records; exact safe integral JSON numbers, depth16 and2048nodes per value. No network stream or external execution. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.

[Technical reference](https://www.rfc-editor.org/rfc/rfc7464.html). No endorsement is implied.

Example input:

```json
{
  "mode": "decode",
  "initialByteOffset": 0,
  "final": false,
  "chunks": [
    "1e7b2261223a317d0a1e22c3",
    "a9220a"
  ],
  "jsonTexts": []
}
```

Selected expected fields:

```json
{
  "/records": [
    {
      "offset": 0,
      "jsonText": "{\"a\":1}\n"
    }
  ],
  "/nextByteOffset": 9,
  "/pendingHex": "1e22c3a9220a",
  "/complete": false
}
```

## URI Template Composite Operator Expansion

USD 1.00 per job.

Expand supplied URI templates with all eight RFC6570 operators, scalar Unicode prefixes, list/map values and explode modifiers. Variable names use the documented ASCII identifier/dot profile; prefix values must be unescaped Unicode strings. Empty composites are undefined; map order follows supplied pairs. At most128variables/expressions and16384output characters. This creates a reference string only, without visiting or validating a destination. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.
