All three want the same three facts about a name — what it is, what it looks like, and where it was written — so the daemon answers all three in one `defs` reply and the client keeps the last one. `defs` is its own op rather than more fields on `describe`. `describe` is what an editor *polls*: it is how the program's output gets drained, and the existing tests ask it in loops. Signatures riding on that would be paid for every time anyone glanced at the output buffer. This is asked once on connect and again after each accepted install, which is exactly when the answer can have changed — so a `defn` typed a second ago completes. It is a cache rather than a request per keystroke because of where these are called from: eldoc fires on an idle timer and completion inside redisplay, and neither may block on a socket or signal. Three refusals rather than three guesses. A global has no location because `Tast.global` carries no `Loc`, and searching the buffer for "(defvar ticks" instead would find the wrong one in a program of several files. The prelude is a string inside the compiler, so its location names a file nobody can visit. A short name that could be several of the program's package-qualified ones is ambiguous, and picking would be a guess about which function you meant — a name that is the tail of exactly *one* is not a guess, and resolves. Functions the checker invented — a lifted handler-bind clause, which carries an `fparent` — are left out entirely: nobody wrote that name, so completing it is noise and jumping to it is meaningless. And the daemon now makes its own source path absolute before building, because every location it reports derives from it. `flan dev src/game.flan` from a project root answered `src/game.flan:12:7`, which an editor can only resolve by guessing what it was relative to. lib/dev.ml is the only compiler file touched: a `defs` op, its three list builders, and the one `realpath` in `start`. Nothing existing changed shape — `describe`, `eval` and `eval-expr` answer byte for byte what they did.
