The daemon side and the Emacs side both landed with nothing written down. Four
files owed something.
`BUILT.md` gets the whole of it: why rooting at an address alone was rejected
and why that rejection was half wrong, what a path step is and how a union's
case travels with it, why the slot goes by index and not by name, and the two
capability lists side by side — the expression root works on a running program
and cannot name a frame; the slot root names one frame and one slot and reaches
an option's payload and a union case's fields, and needs the program stopped.
Neither contains the other, which is the reason there are two.
`emacs/MANUAL.md` says the same thing in the register that file uses, under the
inspector, because the person pressing `i` is the one who needs to know which
root they got and what it cannot do. The globals section's claim that `i` works
on a global "exactly as it does on a local" was true and is now the interesting
difference, so it says what the difference is.
`NEXT.md`'s decided item is struck with what actually shipped: a frame and a
slot index rather than an address and a type, and `l` crossing between the modes
was predicted as a cost and turned out not to be one.
`DISCUSS.md` item 1 is no longer an open question. The number stays — cimport.ml
and NEXT.md cite these by number — and what stays with it is the one correction
worth keeping: an address is not an expression, but a step does not have to be
one either.
And BUILT.md's last paragraph still said `render.ml` prints `(V {:x 1.5})` and
that the printer would move when its reader did. They moved together some time
ago.
