FEATURE: Input Stream Controls

Workflow

Expose the remaining JSON values from the process input stream through input and inputs, while preserving the already-selected current input and generator ordering. Provide the fixed-interface filename and line-number primitives required by the corpus.

Programmatic Acceptance

=== AC io-001-input-conformance ===
Intent: The authoritative corpus cases covering input stream controls execute and pass.
Suite: scoped
Requires: executable=python3; scope=test

import json import os import subprocess import sys

selector = r"input|inputs|input_filename|input_line_number" result = subprocess.run( [sys.executable, "sources/run_conformance.py", "--select", selector, "--json"], capture_output=True, text=True, env={**os.environ, "JQ": f"{os.getcwd()}/jq"}, ) print(result.stdout) print(result.stderr, file=sys.stderr) report = json.loads(result.stdout) summary = report["summary"] assert sum(summary.values()) > 0 assert summary["fail"] == 0 and summary["error"] == 0 assert result.returncode == 0 === END AC io-001-input-conformance ===

=== AC io-001-streams ===
Intent: The selected corpus includes both single-next-input and remaining-input stream behavior.
Suite: scoped
Requires: executable=python3; scope=test

import json import os import subprocess import sys

selector = r"\binput\b|\binputs\b" result = subprocess.run( [sys.executable, "sources/run_conformance.py", "--select", selector, "--json"], capture_output=True, text=True, env={**os.environ, "JQ": f"{os.getcwd()}/jq"}, ) print(result.stdout) print(result.stderr, file=sys.stderr) report = json.loads(result.stdout) summary = report["summary"] assert sum(summary.values()) > 0 assert summary["fail"] == 0 and summary["error"] == 0 assert result.returncode == 0 === END AC io-001-streams ===

User Acceptance

• None.

Guardrails

• Read only the fixed standard input stream; do not add command-line input modes.
• Preserve the distinction between the current input and remaining inputs.
