 It also compares the complete `checksum:` field, so extra or trailing checksum
 text, or a duplicate checksum field, is rejected as `BAD package checksum`.
+The project manifest must also contain exactly one non-empty `name:` field;
+otherwise doctor reports `BAD project manifest name: expected a non-empty name`.
 
 Starter projects created with `claro new MyProject` use the same `manifest-version: 1` and `lock-version: 1` headers as `claro package init`, so the first project files match the package maintenance tools.

 1. Keep beginner-facing docs current and separate from historical release notes.
 2. Keep examples aligned with the modern simple syntax (`END`, `DO`, short `SET`, short `ASK`) while documenting older compatibility forms separately.
 3. Expand validation around typecheck diagnostics and package/networking safety. Current Forgejo/Gitea CI runs the documented release gates (`claro validate`, typecheck diagnostics validation, version convention validation, package security validation, and CI workflow coverage validation). Current package safety validation covers safe project creation, rejecting unsafe project names during `claro new`, safe manifest/lockfile creation, rejecting unsafe package names during `package add`, detecting unsafe package names already present in `claro.project` during `package doctor`, refusing to write lockfile data for unsafe package names during `package lock`, making `package list` fail instead of displaying unsafe package entries as normal package names, making `package init` fail instead of reporting the project ready when unsafe package names are already present, making `package add` fail before changing files when unsafe package names are already present, making `package remove` fail instead of reporting success when unsafe package names remain during lockfile refresh, allowing `package remove` to remove an exact unsafe package entry so learners can repair a bad `claro.project`, making `package doctor` reject stale lockfile checksums for listed packages, and making `package doctor` reject lockfile package entries that are not listed in `claro.project`. Current function validation covers correct checked calls, wrong-type arguments, missing checked-argument diagnostics, missing unchecked-argument diagnostics for simple functions in both modern `DO greet` and empty compatibility `CALL greet WITH` forms, extra-argument diagnostics, and beginner-facing unknown-function diagnostics for mistyped modern `DO` and compatibility `CALL ... WITH` calls; current object-method parameter validation covers correct modern `DO object.method ...` and compatibility `CALL object.method WITH ...` checked calls, wrong-type diagnostics for both call forms, checked methods after another method in the same class, missing and extra checked-argument diagnostics including the extra-argument case for a checked method after another method in the same class, missing unchecked-argument diagnostics for simple object methods, missing-object guidance when `DO player.method ...` or compatibility `CALL object.method WITH ...` appears before `NEW` even if the method name is also wrong, and class-specific unknown-method diagnostics for both modern and compatibility calls when a learner calls a method the class does not declare; current object-field validation covers direct NUMBER/TEXT/YESNO field-assignment positives, direct object-field `CHECK TYPE` metadata positives for NUMBER/TEXT/YESNO fields, negative NUMBER/TEXT/YESNO field metadata mismatches, NUMBER/TEXT/YESNO-expectation unknown-field `CHECK TYPE` diagnostics, direct wrong-type field assignment diagnostics, field collection when a `HAS` field appears after a simple method, direct unknown-field diagnostics for NUMBER/TEXT/YESNO values, a beginner-facing fallback for unknown fields assigned from expressions whose type is not inferable yet, and missing-object diagnostics for both `SET object.field value` and `CHECK TYPE object.field IS TYPE` before `NEW`.

+3a. Keep package validation honest by checking that the project manifest has one non-empty project name, and that the project and each listed package manifest declare the exact supported manifest version, package version, local source, and expected package name.
 3b. Keep package security validation in Forgejo/Gitea CI so unsafe names, exact manifest-version/name/checksum mismatches, missing manifests, duplicate project packages, duplicate lock packages, duplicate package manifest names and checksums, and lockfile errors remain release blockers.
 4. Add small examples for each foundation feature before adding bigger syntax.
