Renames the package to its final names (owner decision 2026-10-25, tracker #19): distribution arcadedb (JVM wheel) and later arcadedb-native, import name arcadedb for both, and no arcadedb_embedded / arcadedb-embedded naming anywhere in this repository. There is no compatibility shim here: the old PyPI packages get a deprecation shim from the humemai repository. The stack of port PRs (#20 to #41) has merged, so the codemod ran on the merged tree and is deleted in this PR.

What changed

• src/arcadedb_embedded moved to src/arcadedb (19 files). The codemod changed 140 other files with 406 replacements: tests 83 / 234, examples 30 / 56, build and verify scripts 8 / 31, docs 8 / 32, CI workflows 3 / 28, package source 6 / 16, packaging metadata 2 / 9 (files / replacements). By rule: distribution or package name 274, import statement 112, repository URL 4, native distribution name 3. All 13 exact-text edits applied. Against main the PR shows 158 files (19 renames, 4 added, 135 modified).
• The codemod was re-run on its own output: nothing moved, every exact-text edit reported "already", zero files changed. scripts/rename_to_arcadedb.py and tests/test_rename_codemod.py are deleted in this PR.
• scripts/check_no_embedded_name.py stays as a permanent guard. It runs as a pre-commit hook and as tests/test_no_embedded_name.py, which the CI test job runs on every platform (the repository has no separate lint job). The allowlist no longer names the codemod; it keeps docs/superpowers/, changelogs, humemai/arcadedb-embedded-python#N issue references, "published as" and "formerly" lines, and lines marked allow-old-name.
• Docs line "This package was published as arcadedb-embedded until 26.10.x; install arcadedb now." in README.md and docs/modules/ROOT/pages/installation.adoc.
• README: the packages table and the status paragraph are rewritten for the new names (arcadedb, arcadedb-native, and a row for the former names). The three places that point to the humemai fork by its URL or name keep it and carry the allow-old-name marker. The README had changed since the codemod was written (the readme-refresh PR), so three exact-text edits were added to the codemod before it ran.
• New import-time warning: src/arcadedb/_dist_conflict.py, called from arcadedb/__init__.py. Both wheels import as arcadedb, so pip overwrites one with the other silently. Importing arcadedb now emits a RuntimeWarning when importlib.metadata finds both the arcadedb and the arcadedb-native distributions; unreadable metadata never breaks the import. tests/test_dist_conflict.py covers the function with a stand-in lookup (both, one, none, broken metadata) and the real import in a fresh interpreter with fake .dist-info directories. The installation page says to install only one of the two and mentions the warning.

Not touched: Java package names (com.arcadedb...), ARCADEDB_* environment variables, engine artifact names, history, and the generic word "embedded" (kept in the pyproject description and keywords).

Checks

• pre-commit run --all-files passes black, isort, shfmt, actionlint and the new hook. "Pretty format YAML" fails on docs/antora.yml (version: ~, indented nav); it fails the same way on current main, so that file is left as it is.
• Source-level import arcadedb (with PYTHONPATH=src, JPype installed) works.
• 95 tests that need no wheel pass in 13 files, pinned to cores 0-3: the new test_dist_conflict.py and test_no_embedded_name.py, plus test_extract_version*, test_check_test_skips, test_build_scripts, test_build_wheel_check, test_build_no_uv_refresh, test_no_monorepo_wording, test_wheel_size, test_stage_jars, test_wheel_licences and test_example11_degree_matching. The wheel build and the engine tests were not run locally; CI builds and runs them.

Order on cutover day

Merge this, then release arcadedb 26.11.1 from this repository, then the humemai shims (see .notes/DECISIONS.md). Until 26.11.1 is on PyPI, pip install arcadedb gives the placeholder, and import arcadedb works only from a source checkout or a wheel built here.
