Migrate node's rsmt2d imports, generated mocks and nested tastora module to the independent library in celestia-app #8312. Pin app at the migration-only v10.4.0 backport #8314 simultaneously so exported EDS/tree types use the same Go import path.

The backport preserves node's current app API, Fibre defaults and dependency versions. Current app v10.x is deliberately not used: it contains additional Fibre interface/default changes. Outside the new rsmt2d path and app commit, dependency versions are unchanged in both modules.

Preview module/app commits are real and resolvable. Replace both pseudo-versions with the corresponding published releases before releasing node; maintainer selection of the app v10.4 release branch is pending. No release or tag is created here.

Validation: all root packages compile (go test -run '^$' ./...); EDS, shwap, IPLD, header and store suites pass; both module manifests tidied; changed imports checked with the repository's goimports-reviser configuration. The rsmt2d library's repeated race tests and old/new root/repair/JSON parity checks also pass. Nested tastora manifests were tidied, but its Docker integration suite was not run.

Review level: [high] — app and node exchange exported EDS types across a Go module identity change. Draft pending coordinated app/library releases and CI.

CI note: the Go Mod Parity Check reports two pre-existing mismatches (Azure/go-ansiterm and docker/go-connections). Complete module lists generated from untouched baseline 55a5be2 reproduce exactly the same two mismatches; neither dependency declaration changes here. Root/tastora tidy and import lint pass. This unrelated baseline CI failure remains visible rather than adding dependency upgrades to the migration.

Final CI snapshot: Linux and macOS unit tests, coverage, golangci-lint, import lint, tidy and OpenRPC generation all pass. Only the baseline parity mismatch above fails; Docker-based integration tests were skipped.

Confidence Score: 5/5

[High impact] No blocking issue is identified. Replacing the preview dependency pins remains a documented prerequisite for releasing node, rather than an unresolved merge blocker.

Summary

Migrates node code, tests, and generated mocks to github.com/celestiaorg/celestia-app/rsmt2d, with matching app pins in the root and Tastora modules. No actionable correctness issue is reported.

rootulp explicitly deferred replacing the preview pseudo-versions with published releases until the coordinated app/library releases are available; maintainer selection of the app v10.4 release branch remains pending.

rootulp explicitly left the Azure/go-ansiterm and docker/go-connections parity mismatches outside this change because both reproduce on the untouched baseline and neither dependency declaration changes here.

• Node data-availability code now uses the same rsmt2d package as Celestia app.
