Detailed Description

What constrained one decode, and what asked for it (gh#154).

The engine always knew this and no consumer could ask. GrammarRegistry:: get() returns "" on a miss, the engine logs a warning, and the decode proceeds UNCONSTRAINED — so from outside, a constrained run and an unconstrained one produce output of the same shape whenever the prompt also describes the shape. The only distinguishing signal was the ABSENCE of a log line, which is not something a consumer can assert on; three days of speculative-decode measurements were published against it and withdrawn.

source names who ASKED. resolved says whether a grammar text actually reached the sampler. They are separate on purpose: a named key that does not resolve is exactly the state that was undiagnosable.

◆ conflict_winner

std::string entropic::GrammarProvenance::conflict_winner

The winning source when two grammars collided ("" = no collision).

A request grammar displacing a tool-call grammar means the staged tools were NOT structurally enforced.

Definition at line 54 of file generation_result.h.

◆ key

std::string entropic::GrammarProvenance::key

Registry key / frontmatter stem that was named ("" = none).

Definition at line 46 of file generation_result.h.

◆ resolved

bool entropic::GrammarProvenance::resolved = false

true when a grammar text actually constrained this decode.

Definition at line 49 of file generation_result.h.

◆ source

std::string entropic::GrammarProvenance::source = "none"

"request" | "tier" | "tool_call" | "none".
