+Breaks the mutual wait recorded on STATE-WP-0079-T04. T04 waits on hub-core
+receipts HUB-WP-0011-T03 and HUB-WP-0006-T06. Both of those wait on artifacts
+that State Hub owns. This plan delivers those artifacts. It does not switch any
+route: switches stay under STATE-WP-0079-T04 and the founder's 2026-10-05
+writer authorization (913b924b), with old-route fallback and metered
+acceptance retained by State Hub.
+
+## A5 topic-spine comparison packet
+
+```task
+id: STATE-WP-0098-T01
+status: todo
+priority: high
+```
+
+Input for HUB-WP-0006-T06. Enumerate the A5 topic/classification read
+endpoints (8 per `docs/retirement-cutover-slice-plan.md`) and their actual
+callers from the legacy meter. Capture legacy response shapes. State the alias
+expectations: legacy topic ids and slugs versus registrar `repository_id`.
+Define concrete comparison cases against the deployed hub-core projection.
+Name the fallback route. Deliver as `docs/a5-topic-spine-comparison-packet.md`
+plus a JSON case list, and notify hub-core.
+
+## A4 work/repo UI caller inventory and owner asks
+
+```task
+id: STATE-WP-0098-T02
+status: todo
+priority: medium
+```
+
+Enumerate the 22 A4 UI read endpoints and the clients that call them. Name the
+UI/client owner for each. Ask each owner for a candidate read smoke and a
+reversible switch plan. Record the owners and requests in the A5 packet's
+companion section. A4 redirects stay behind the retained UI as rollback.
+
+## Inbox change-feed contract
+
+```task
+id: STATE-WP-0098-T03
+status: todo
+priority: high
+```
+
+Input for HUB-WP-0011-T01. Specify a versioned State Hub inbox change feed:
+a consistent snapshot plus a monotonic revision/cursor; read/archive state
+changes; deletion versus retention semantics (tombstones; State Hub stays the
+only message writer); replay/compaction recovery; and source timestamps for
+freshness. Deliver as `docs/inbox-change-feed-contract.md`. Any
+retention/ownership choice that the existing T08/T09 record does not settle
+goes to the founder before hub-core implements against it.
+
+## Named single reader and parity window
+
+```task
+id: STATE-WP-0098-T04
+status: todo
+priority: medium
+```
+
+Input for HUB-WP-0011-T03. Name the one inbox reader to switch first. Give
+its parity sample/window and the rollback endpoint (current State Hub
+`/messages/`). Get the reader owner's agreement. This depends on T03 being
+accepted by hub-core.
