- [ ] milestone: Honey compiles its production compiler, then that compiler compiles itself again and builds/runs the example programs.
## observed baseline
## current boundary
`./build/honey run source/main.hon` exits `1`: import declarations produce
`unexpected token`, qualified names produce `invalid character` at `.`, and
recovery ultimately reports a missing entry point. an isolated import followed
by a supported `main` still prints `42` but exits `1`; recovery is not import support.
the driver now retains frontend storage through `@source/compilation`; source IDs
qualify local AST declaration IDs, and package IDs retain source membership.
CLI commands still compile one source. the unchecked items below remain planned support.
directory loading and import declaration discovery are implemented; qualified
namespace selection and the richer types/control flow used by the compiler
remain unsupported. the driver retains frontend storage and source provenance
through `@source/compilation`, with compilation-wide AST node identities.
file commands retain single-file behavior; directory commands compile the
package's production files and load its dependencies in separate scopes.
## next milestone: scalar-function packages

- [x] retain source/package identity and source ownership across the compilation; keep one identifier pool and unambiguous declaration IDs.
- [ ] load directory packages once per canonical path, with deterministic file discovery, package scopes and root-only entry selection. follow Bro's existing relative and project-root `@` import rules; diagnose cycles rather than recurse indefinitely.
- [ ] parse bare and aliased imports plus postfix namespace selection; resolve file-local import aliases without injecting dependency names into the importing package.

- [ ] finish postfix namespace selection and resolve file-local import aliases without injecting dependency names into the importing package; bare and aliased import declarations are already parsed for dependency discovery.
- [ ] reuse ordinary scalar signature checking, function values and IR calls for selected declarations; namespaces have no runtime representation.
- [ ] preserve originating filenames and spans in dependency diagnostics and native runtime traps; retain demand-driven diagnostic recovery.
- [ ] verify sibling source files, transitive/shared imports, same-spelled declarations in different packages, alias conflicts, missing packages/members, argument errors and dependency-file diagnostics. preserve existing single-file commands.
