# FEATURE: Streaming Transformations

| Field       | Value |
|-------------|-------|
| Version     | 20260822 V1 |
| Description | Provides jq streaming conversion and truncation filters. |
| Depends On  | ARCHITECTURE.md |
| Provides    | tostream, fromstream, truncate_stream |
| Consumes    | ordered generator evaluator, path primitives |

## Questions

- None.

## Workflow

The implementation exposes `tostream`, `fromstream`, and `truncate_stream` as generator-aware filters. Streaming values use jq path/value records, preserve ordering, and reconstruct composite JSON values without mutating the source.

## Programmatic Acceptance

=== AC io-003-conformance ===
Intent: The streaming transformation cases selected from the authoritative corpus execute and pass.
Suite: scoped

import json
import os
import subprocess
import sys

selector = r"tostream|fromstream|truncate_stream"
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
assert summary["error"] == 0
assert result.returncode == 0
=== END AC io-003-conformance ===

## User Acceptance

- None.

## Guardrails

- Streaming filters must preserve generator order and must not depend on external runtimes or network access.

# FEATURE: Conformance Asset Staging

| Field       | Value |
|-------------|-------|
| Version     | 20260822 V1 |
| Description | Stages and validates the immutable jq conformance assets. |
| Depends On  | ARCHITECTURE.md |
| Provides    | sources/ conformance corpus, manual, grammar, harness, exclusions, full-test script |
| Consumes    | target application root |

## Questions

- None.

## Workflow

The supplied source assets are staged byte-for-byte beneath `sources/`. The harness parser is imported directly to validate corpus structure and exclusion consistency without launching the candidate interpreter.

## Programmatic Acceptance

=== AC conf-001-assets ===
Intent: The staged corpus parses into the authoritative case set and all declared exclusions match cases.
Requires: executable=python3; scope=test

import sys

sys.path.insert(0, "sources")
import run_conformance as harness

cases = harness.parse_corpus(harness.CORPUS.read_text(encoding="utf-8"))
excluded = harness.apply_exclusions(
    cases,
    harness.parse_exclusions(harness.EXCLUSIONS),
)
assert len(cases) == 550
assert len(excluded) == 13
assert harness.CORPUS.is_file()
assert harness.EXCLUSIONS.is_file()
=== END AC conf-001-assets ===

## User Acceptance

- None.

## Guardrails

- The supplied scoring assets remain read-only and are never modified, rewritten, filtered, or substituted.

# FEATURE: Scoped Conformance Verification

| Field       | Value |
|-------------|-------|
| Version     | 20260822 V1 |
| Description | Provides executable, machine-readable scoped conformance verification. |
| Depends On  | ARCHITECTURE.md, FEATURE-CONF-001.md |
| Provides    | scoped conformance execution with JQ candidate binding |
| Consumes    | ./jq, sources/run_conformance.py |

## Questions

- None.

## Workflow

Scoped verification invokes the supplied runner against a construct selector, extends the inherited environment with the candidate executable through `JQ`, parses the runner's JSON report, and requires every selected case to pass without errors.

## Programmatic Acceptance

=== AC conf-002-scoped-run ===
Intent: The authoritative reduce slice executes selected cases and passes through the candidate executable.
Suite: scoped

import json
import os
import subprocess
import sys

result = subprocess.run(
    [sys.executable, "sources/run_conformance.py", "--select", r"reduce", "--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
assert summary["error"] == 0
assert result.returncode == 0
=== END AC conf-002-scoped-run ===

## User Acceptance

- None.

## Guardrails

- Scoped verification must execute selected cases and must never use enumeration, dry-run, or unscoped execution as its product verdict.

# FEATURE: Complete Conformance Verification

| Field       | Value |
|-------------|-------|
| Version     | 20260822 V1 |
| Description | Runs the complete jq conformance corpus as the terminal release verification. |
| Depends On  | FEATURE-IO-003.md, FEATURE-CONF-002.md |
| Provides    | complete jq conformance release verification |
| Consumes    | ./jq, sources/full_test.sh |

## Questions

- None.

## Workflow

As the terminal verification, this story runs the supplied `sources/full_test.sh` without filtering or reinterpretation. The script validates the executable boundary and runs the complete non-excluded corpus.

## Programmatic Acceptance

=== AC conf-003-full-suite ===
Intent: The supplied complete conformance suite passes with a successful exit status.
Suite: full

import subprocess

result = subprocess.run(
    ["sh", "sources/full_test.sh"],
    capture_output=True,
    text=True,
)
print(result.stdout)
print(result.stderr, file=__import__("sys").stderr)
assert result.returncode == 0
=== END AC conf-003-full-suite ===

## User Acceptance

- None.

## Guardrails

- This is the only story that runs the complete corpus.
- The scoring script and its exit status are authoritative; its output is diagnostic only.
