Code
// A STANDING RULE CAN NAME THE HANDLE OF THE ROW IT IS VISITING, and the
// handle it hands out is RETAINABLE — it still addresses that row after a
// swap-remove has moved the row somewhere else.
//
// `[id]` landed on sweep arms first (690_246). On a `rule` arm any destructure
// was refused as "the retired projection block" — a wrong error on a legal
// construct, since a request block is not a projection block. RULED 2026-08-03:
// `[id]` is admissible here, and the gate is why. Clause 1 says the request
// names something the SITE knows and the ROW does not, and SITE is deliberate:
// a rule has a ROW and no TRAVERSAL, so a handle is exactly as meaningful here
// as on a sweep (a handle does not depend on traversal) while `[ordinal]` is
// meaningless and refused BY NAME (690_248). A gate phrased around "the VISIT"
// would have collapsed *meaningless here* into *unimplemented here*.
//
// WHAT THIS PROVES, and it is the retention clause end to end:
//
// units: a(hp 10) -> dense 0, b(hp 20) -> dense 1, c(hp 0) -> dense 2
// the rule enters on c's insert, `[id]h` names c's HANDLE, the body writes it
// into a sibling store — the external index the store never maintains for you
// take(units[b]) swap-removes b, RELOCATING c from dense 2 to dense 1
// `units[mark.who].hp: 777` follows the STORED handle
//
// The 777 lands on c at its NEW position. A position would have addressed dense
// 2 — past `len`, inside capacity, writing nothing anyone reads, which is
// exactly the silent corruption 690_092 measured before O10.iii shipped. So the
// value `[id]` mints on a rule arm is the same handle `| row` mints, carrying
// brand and generation, and clause 2 of the gate ("a value that may OUTLIVE the
// visit must be generation-checked") is satisfied rather than assumed.
//
// The motivating workload is the one that earned `[id]` in the first place: a
// reactive chain update needs the visited row to name itself as a value.
