Development record

The brief at .abcd/development/brief/05-internals/03-configuration.md:847 says: prompt-router stdout carries 'the rendered block of the domains new this turn, and nothing else'; the --json envelope's fields are text, injected, active and error. The shipped surface differs: `abcd hook prompt-router --help`: plain stdout is the rule block 'followed by a "## MEMORY" block of the memory notes the prompt recalls', and the --json envelope is {"text", "injected", "recalled", "active", "error"}; the chapter does not mention the memory block or the `recalled` field. (v0.14.2 release crosscheck, false-claim, raised by opus in a34.)
