Changes touching this path

• the shorthand whose NAME states the path axis while its SHAPE states the arity axis is DELETED, so the terse spelling is now the one that REFUSES - which was this ticket whole thesis, that the wrong declaration was cheaper to write than the right one and that is why the silent-drop class kept recurring. every site that meant it now types the open constructor out, and the only shorthand left is the one that takes nothing. option A beat option B on BOTH axes, measured rather than preferred: B would have changed the constructor signature, so EVERY open call site owed a reason string - including the path-taking and the genuinely variadic ones - and the two dozen dispatch verbs would each have written the SAME sentence, which is boilerplate that teaches nothing and is itself a hand-maintained population. so A has the smaller blast radius AND the stronger property. the blast radius is ZERO BEHAVIOURAL, because the retired constant was literally that expression: no verb declared arity, no slot kind and no refusal moved - thirty-five declaration sites, eleven imports and about twenty-five prose sites, with the workspace check clean and no new warnings. the exemption list was ALREADY down to its two legitimate names before this began, since #1569 narrowed the other twenty-one hours earlier, so nothing was added to it or taken from it, and the #545 refusal that earns those two their place is untouched by construction - pinned rather than incidental, because the mutation that hands one of them the no-arguments declaration reddens all three censuses. the rename then exposed two more counts standing beside sets that MOVE, and both are fixed rather than carried: a fixture doc claiming all FOUR verbs it exists to serve are exactly this shape, where there are FIVE production attachers and NONE of them is that shape, and a line naming the four verbs that used the retired constant. both now state the rule and count nothing. the new guard refuses BINDING the zero-slot open claim to a name, which is the single edit that would undo this, while deliberately NOT refusing a leaf that spells the claim out at its own spec - the two told apart by what PRECEDES the constructor, with both run through the predicate before its answer is read. its limits are in its own header. and the control that mattered is the second: with the comment-strip removed AND the predicate control disabled, the tree scan names the flags file itself, over the retired declaration QUOTED INSIDE THE SURVIVING CONSTANT OWN DOC - so the strip is load-bearing rather than decorative. the first and third mutations are each other discrimination, one reddening only the tree arm and the other only the binding-versus-spelling arm, and the fourth proves the floor fires at zero files rather than agreeing silently (#1675) 123fdbd4 · dbf3dbe6…

Renames are not followed. loot's tree maps a path to an address, so a rename is a delete and an add. This list is the history of the name, not of the bytes.
