Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When Set or Delete is called with key paths containing Unicode characters, the parser shall correctly resolve the path and perform the mutation or return a well-defined error without panicking.
the parser shall always satisfy !mutation_input_has_unicode_keys | mutation_handles_unicode_keys_safely

Rationale & tags
Why this requirement exists, and how it is categorised.
JSON object keys can be arbitrary Unicode strings. Mutation helpers must handle non-ASCII key paths without corrupting the document.

The formula requires Unicode key paths to either resolve and mutate correctly or fail cleanly without panicking. Set (parser.go:1397) and Delete (parser.go:1238) delegate to setConfig/deleteFoundConfig, which match keys byte-wise through internalGet with no decode step that could panic on multi-byte input. TestMutationUnicodeKeys (obligation_property_test.go:758) exercises Set/Delete on a document carrying a raw UTF-8 key and confirms the mutation applies and the document stays parseable, and the MCDC Row2 witness confirms a non-nil result for a Unicode-key Set. The Set/Delete demo defects KI-3/KI-4/KI-16 are confined to array-index and root-delete paths, none of which this requirement's Unicode-string-key cases touch; all witness tests pass.

Obligations
What this requirement must witness to be considered satisfied — the required evidence, and the tests that discharge each one.
The tests that discharge each obligation aren't available for a historical run
The evidence matrix behind each obligation comes from the live audit index, which can't be rebuilt for a past commit. Nothing here means unknown — not that the requirement has no obligations.
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).

MC/DC truth table· 3 rows
Each row assigns the formula's conditions (T/F) and shows the Result— the formula's value for that input row, not a test pass/fail. A row proves a condition when flipping only that condition flips the outcome. The test that covers each row is linked.
