Merge branch 'worktree-tensorx-provider' into main

🤖 merge: slice 1 — the sibling contract, §4.1's ruling on every search, and gate 8

Discussion 3. Thirteen commits, three independent reviews, every gate
mutation-tested with survivors chased rather than argued away.

Two spec amendments where §8.1 disagreed with itself: the breaker's
window is a UTC day (day-keyed counters cannot answer a rolling
question), and its NOT_VISIBLE clause binds each counted asker rather
than the window — §13 already had that fix and §8.1 was amended without
opening it.

Three rendering bugs found that predate this work: rst-callout,
rst-btn and rst-cell-mut all spelled outside the design system's
vocabulary. The first is fixed with a gate; the other two are listed by
name and left for Paul, because which variant a button should be is a
visual decision.

Blocked and recorded in §13: post-restore reconciliation, S1a's
re-announce and gate 27 all need AHEAD in the contract module.
