When a JSON object member key is escaped in the payload and the decoded path segment matches that logical key value, Get shall resolve the member through the normal successful lookup contract.

Specification

The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.

Description

When a JSON object member key is escaped in the payload and the decoded path segment matches that logical key value, Get shall resolve the member through the normal successful lookup contract.

FRETish formula
the parser shall always satisfy !escaped_json_object_key_is_present | !decoded_path_segment_matches_escaped_key | returns_value_from_decoded_escaped_key

Rationale & tags

Why this requirement exists, and how it is categorised.

Escaped-key matching is caller-visible compatibility behavior and should be specified directly rather than left implicit in helper implementation.

Obligations

What this requirement must witness to be considered satisfied — the required evidence, and the tests that discharge each one.

No obligations recorded for this requirement

Proof obligations are recorded once evidence is generated. None have been captured here yet — this is expected, not a gap in the requirement itself. A required class of evidence the requirement must witness — the bridge between the requirement existing and it being proven.

Formula evidence

The formal formula behind this requirement, the variables it is written over, and the tests that exercise it (each term is explained inline).

FRETish formula

the parser shall always satisfy !escaped_json_object_key_is_present | !decoded_path_segment_matches_escaped_key | returns_value_from_decoded_escaped_key

Variables

NameTypeDirectionDescription
escaped_json_object_key_is_presentTrue when the addressed object member key is encoded with JSON escape sequences in the payload.
decoded_path_segment_matches_escaped_keyTrue when the decoded lookup path segment matches the logical value of an escaped JSON object key.
returns_value_from_decoded_escaped_keyTrue when Get resolves an escaped JSON object key by comparing the decoded path segment to the logical key value.
