Mirrors the cacheReason treatment: ppr_state in the description, prompt signals (ppr state / ppr_state / x-vercel-ppr-state), retrieval alias + entity, and a PPR state concept table (page/shell/blocking -> Static/ Partial/Dynamic) next to the cache-reason section. Regenerated manifests. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Adds

ppr state,ppr_state,x-vercel-ppr-state) + retrieval alias/entitya PPR state concept table under Key concepts, right after the Cache reason table:
ppr_statepageshellblockingplus how to read it (
vercel logs, dashboard Logs panel,vercel metrics --group-by ppr_state) and the internal-onlyx-vercel-ppr-stateheader note.regenerated
generated/manifests.Why
ppr_stateis a per-request PPR field the proxy now emits (page/shell/blocking), surfaced invc logs, the Logs panel, andvercel metrics. It belongs next tocacheReasonin the CDN caching skill since PPR's static shell is served from the ISR cache.
