 Nine content PRs to migrate learn.internetcomputer.org articles into `docs/`. Source staging files are in `.migration/learn-hub/`. Full article-to-file mapping and cross-link instructions: `.docs-plan/learn-hub-navigation.md`. Per-batch agent workflow: `.docs-plan/learn-hub-migration.md`.
 
-| Batch | Branch | Target files | Effort |
-|---|---|---|---|
-| 1 — Protocol stack | `docs/concepts-protocol-stack` | `concepts/protocol/index.md`, `consensus.md`, `peer-to-peer.md`, `message-routing.md`, `execution.md`, `state-synchronization.md` | Large |
-| 2 — Node infrastructure | `docs/concepts-node-infrastructure` | `concepts/node-infrastructure.md` | Medium |
-| 3 — Edge infrastructure | `docs/concepts-edge-infrastructure` | `concepts/edge-infrastructure.md` | Medium |
-| 4 — Evolution & scaling | `docs/concepts-evolution-scaling` | `concepts/evolution-scaling.md` | Small–medium |
-| 5 — Chain Fusion deep dives | `docs/concepts-chain-fusion-deep-dives` | `concepts/chain-fusion/index.md` (moved), `bitcoin.md`, `ethereum.md`, `solana.md`, `dogecoin.md`, `exchange-rate-canister.md`, `chain-key-tokens.md` | Large |
-| 6 — Cryptography deep dives | `docs/concepts-cryptography-deep-dives` | `concepts/certified-data.md`, expand `concepts/chain-key-cryptography.md` | Medium |
-| 7 — Governance deep dives | `docs/concepts-governance-deep-dives` | expand `concepts/governance.md`, `concepts/sns-framework.md`, `references/nns-proposal-types.md`, `references/sns-dao-settings.md` | Large |
-| 8 — Tokens & ledgers | `docs/concepts-tokens-ledgers` | `concepts/tokenomics.md`, `concepts/token-ledgers.md`, expand `concepts/cycles.md` | Medium |
-| 9 — Canister concept fillers | `docs/concepts-canister-fillers` | `concepts/principals.md`, expand `concepts/canisters.md` | Medium |
-
-Recommended order: batches 1–4 can run in parallel. Batch 8 before batch 7 (governance links to tokenomics). Batches 5, 6, 9 independent.
+To claim a batch: check `git ls-remote origin docs/concepts-*` — branch exists means claimed, open PR against `infra/learn-hub-migration-prep` means in progress, branch gone (merged) means done. No GitHub Issues needed. Full workflow: `.docs-plan/learn-hub-migration.md`.
