Recovery fix, member of the group fix/1966-views-page-time (mesh-sdk, mesh-tools, mesh-host), merged as one group.

Cause

mesh-grants' first view of mesh-delivery-assigner.wants has failed every minute since 2026-11-09 00:42 UTC with "the page after "", failed after 30.001s: context deadline exceeded". views.FirstView listed the keys and then made one KeptState.Get bus request per key, up to 768 KiB a page. The wants state is 387 keys and 1.7 MB, so one page was about 170 requests, past the reader's 30 s. With no grant written, distribution's move on novox (the artifact store) cannot proceed.

Quick or thorough

Quick: a smaller page.
Thorough, chosen: a page is read in one request through the runtime's new state verb mesh/state.page (mesh-tools), with KeptState.Page and an optional Pager interface. FirstView falls back to per-key Get when the runtime lacks the verb, matched by code -32601. Every page is also bounded by time (views.PageBudget, 10 s, sent as budget_ms), always with at least one value and Next for the rest.

Evidence

New cases are subtests in the existing first-view table, and a refusal row in state_test.go. Each fails without its change.
The unit suite, go vet and go vet -tags integration pass.

Rules bent (rules-are-weighed)

No test proves the budget cuts a page before the deadline: it holds by construction, since every bus request in the loop has its own deadline, and a test would need real sleeping. The reviewer agreed.

Undo

Revert the group's merges.
