<reusable-compact filename="ARCHITECTURE.md">
- Executable: `./jq -c '<program>'`; compact JSON lines on stdout.
- Exit codes: `0` success, `3` compile failure, `5` runtime failure; diagnostics on stderr.
- Standard-library Python only; no external jq, dependencies, networking, or persistence.
- Modules: CLI, lexer, parser/AST, evaluator streams, runtime values, builtins, paths/assignment, diagnostics.
- Preserve generator ordering, multiplicity, backtracking, immutable transformations, and partial output.
</reusable-compact>

RESULT: SUCCESS

FILES CHANGED:

SUMMARY:
Established the standalone Python interpreter architecture, executable boundary, module contracts, exit-code handling, streaming identity behavior, immutable path reads, and foundational tests. All 5 tests pass. No staged conformance suite was run because this architecture specification declares no programmatic acceptance.

BLOCKERS:
- None
