docs: fix re-review findings — seat-migration obligation, evidence rule moved into the standard, first-cut family settled

Restore the ReactNode seats' pending-migration obligation the earlier
rewrite had flipped into a permanent exception; state the merged-PR/issue
evidence allowance in docs/AGENTS.md itself so the citations note defers
to the standard instead of overriding it; rewrite the one current-state
'first cut' fact and record the historical-stage-name exemption (with
indexical stamps still banned); pairs re-recorded.

@@ -23,7 +23,7 @@ How live data reaches render code, and what may cross a business boundary:
1. **Everything a render reads that can change outside React arrives through a framework hook** (rule 4 above). Event-handler code may read live snapshots (e.g. `keyboard.snapshot`); render code subscribes.
2. **Business components contain no subscription machinery** — no `useSyncExternalStore`, no manual subscribe wiring, no mirroring an external snapshot into local state or a second store. Give each reactive fact its owning channel instead: registrant-private → the inject `hooks` compartment; cross-entry or remount-surviving → a declared store; per-session standard → `sessions.provide`.
3. **Data-access ladder** — resolve needs in this order: framework hooks (standing seats + provide/inject-bound `use<Name>`) → a declared store (`useStore`/`actions`) → inject callbacks → anything else is a new framework extension point and needs main-thread arbitration.
4. **Contract currency is JSON-able data and callbacks.** Everything crossing a business boundary (owner props, inject faces, store state, provide contributions) is plain serializable data or a callback over such data; the inject `hooks` compartment is the one sanctioned carrier of bare observables, and components never see those either. ReactNode is not a currency: route render content through a slot; no new ReactNode-valued owner props or inject members (the composer's existing `accessory`/`overlay`/`leftItems`/`rightItems` seats are the sanctioned exceptions).

5. **An observable source keeps two identities stable**: the source object itself (hook binding is cached per source), and its snapshot between changes (`getSnapshot` returns the same reference until the fact moves).
6. **Whoever rebuilds a published value republishes it through the same source in the same step**, and a registration path that can run after consumers exist notifies the live consumers as part of registering.
