WIP: recheck a take's filesystem, follow only the module's branch, count users in an access change, hold the identity until its data is taken (hq ADR 0325 review)

A keep wait on a filesystem that cannot carry ACLs is not excused, and nothing is asked; one whose
filesystem must first enable them says in the ask that the take sets it. The tool runner's account is sent
with no uid, for the engine to resolve by name.

-// than the one its machine was last sent** (novox/hq issue 201). Every send made through sendToEach keeps it — a
-// plan's, a release's, a healer's, a rotation's, and the bus step too, which is a person's act but composes under
-// sendKeeps like the rest. On 2026-10-02 two merges a minute apart made two plans;
-// the controller's plan rolled the new controller, which widened its seat's row, and the node-engine's plan then
-// sent the control node the controller build before it. The older binary read the row it could not serve and the
-// mesh lost its voice for ten minutes — the thing that would have corrected it was the thing that was down. ADR
-// 0185 took the outage out of it (a controller behind its row serves what it can); the race is closed here,
-// without needing its trigger: whatever made the mesh's record older, the send keeps the build.
-//
-// **Kept, not refused.** The send composes the controller or the node-engine at the build the machine was last
-// sent, as a recorded module is kept (ADR 0245), and carries everything else: no other module, secret, healer or
-// walk waits on it, and nothing is retried. The kept move is no move for a gate either: ungatedIn and gatedSend
-// leave it out (withoutKept), so a gate judges the other moves of its send. A plan whose own build is the older one finds its gate superseded by
-// the build kept there (issue 352) and ends. The mesh's record stays older, and a warning condition says so until
-// a send carries the record — a person's `push <node>` accepts the older build — or the record moves forward: a
-// newer merge, or `rebuild mesh-controller`.
-//
-// Older is by the builds' registration order — when each was asked (novox/hq issue 219) — never by the commits'
-// dates. So a retry or a rebuild of an old commit, asked anew, counts as newer: it is registered as the module's
-// current build by the same order, and the guard does not stop that move. A build that failed its gate is never
-// ahead: the machine was sent it and the record was put back before it (gateFailed), and if the put-back's own
-// send was refused, the next send completes it rather than keeping the failed build there. A gate's own put-back

+// The mesh takes a shared folder that already holds data once, on the operator's word (novox/hq ADR 0325 §7, §8).
+//
+// **What waits.** A node-engine that keeps folders states an access waiting, naming it (inventory.Wait.Access), while
+// its folder is there and has not been taken; the controller excuses that wait only for a declared, placed folder not
+// yet taken (checkAccessWait), and the module is said as its needs-operator condition, in words with no path.
+//
+// **One ask per folder and machine.** The serving controller's asker asks the operator once for each such folder on
+// each machine — however many modules wait on it — at the level approve (ADR 0259), in the clause's words: "Let the
+// mesh keep <path> on <machine>, now for <modules>: …". It is kept in the controller's asks beside a proposal
+// (asked.Take), never a condition's: the condition is the module's, and two modules waiting on one folder are one
+// question. While it is open no second is asked; one that expired unanswered is asked again while the folder waits;
+// one about a folder that no longer waits is taken back. None is asked for a folder already taken, so a module that
+// joins a taken folder is asked nothing (its access wait is not excused, and its entries are added at apply).
+//
+// **On the warrant, and only on it**, the controller asks the machine's engine to take the folder (link.AskTake),
+// naming the access by its resource id and the warrant; the engine adds the entries of the users it was declared for
+// that folder. On its word that it started, the folder is recorded taken (kept_folder), and from the next send every
+// access to it says `taken`. Where the engine's wait says the filesystem must first allow ACLs (acl
+// "needs-enabling"), the ask says the take sets that; where it cannot carry them (acl "unsupported") the wait is not
+// excused and nothing is asked.
