Two review threads from PR 4, and the answer to the third. The routine status was a bare string with its legal set in a comment. Nothing caught a typo at compile time, nothing enumerated the set for a test, and a bad value surfaced as a /routines row that neither accepts nor dismisses. It is a RoutineStatus now, with the three constants, a RoutineStatuses slice as the single source of truth, and Valid(). Listing by an unknown status is refused with ErrRoutineStatus instead of answering "no rows", which is what a correct query says about an empty table. A round-trip test moves a routine into each state and reads it back, so a constant that drifts from the inline SQL fails loudly. The hand-rolled framing stays, and frame.go now says why: ninety lines, readable with socat, and every standard replacement brings schema machinery this boundary does not want. What was wrong was inheriting it untested. frame_test.go covers the paths a real socket produces and the round-trip test never does — truncated header, truncated body, one byte per Read, two frames back to back, and a non-JSON body. Empty input is the only EOF. The unanswered question in the same file is answered in place: a routine object stays a local string, not a Nexus ref, because nothing acts on it. It is the word he used, replayed back to him, compared only against itself for the UNIQUE key. Canonical refs arrive if a routine ever drives a Hexis call, which is V-272. The mood enum has the same shape and is not done here: it is spelled in the GBNF grammar, three prompts and the parse, so it is its own change.
