ProbeLabsviewing a historical runWhen internal helper blockEnd returns -1 indicating no matching closing bracket or brace was found, all callers of blockEnd shall treat this as a malformed-structure condition and shall not proceed with normal value extraction.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When internal helper blockEnd returns -1 indicating no matching closing bracket or brace was found, all callers of blockEnd shall treat this as a malformed-structure condition and shall not proceed with normal value extraction.
the parser shall always satisfy !blockEnd_returns_negative_one | caller_handles_blockEnd_sentinel

Rationale & tags
Why this requirement exists, and how it is categorised.
blockEnd returning -1 is a sentinel value that indicates truncated or malformed structural input. All callers must check for this before using the return value as an offset.
Verification & provenance
How this requirement was checked: the review trail, edit history, and the machine-analysis status terms (each ⓘ explains what it means).

blockEnd/blockEndConfig (parser.go:376) return -1 on an unmatched bracket/brace. Callers handle it as malformed-structure: array/object skips in searchKeys return -1 (parser.go:840, parser.go:1071, parser.go:608), the object-brace skip returns -1 (parser.go:552), internalGet raises MalformedArrayError/MalformedObjectError (parser.go:1600, parser.go:1610), and the top-level array append returns MalformedArrayError (parser.go:1466). The two container-skip sites at parser.go:159/164 simply leave the index unadvanced on -1 rather than dereferencing, which is also a safe handling. MCDC Row3 sentinel-handled witness passes.

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.
