Do you need a standalone gate?
If DVC, MLflow, Snakemake, or another reviewed control already covers this job, keep it. v1 is for one small local contract.
Paid local software · v1.0.0 · Private delivery
Stop a replay before missing or changed inputs reach it.
Declare the local authority files, inputs, exact identities, discovery rules, and byte limits another tool should require. Replay Input Preflight returns READY, REVIEW, or BLOCKED without invoking the replay.
Already using DVC, MLflow, Snakemake, or an equivalent input gate? Keep it. This package is for a small standalone local contract and verifiable evidence pack. No account is required to run it; no checkout is active. Do not send replay inputs, datasets, code, credentials, or private strategy material.
01 / InputOne strict JSON contract
Declare the workspace, authorities, expected inputs, exact hashes, discovery rules, and hard ceilings.
02 / OutputThree small evidence files
Retain report.json, summary.md, and SHA256SUMS.txt in a deterministic create-only pack.
03 / BoundaryZero replay execution
The tool reads only declared local paths and makes no runtime network request, upload, or telemetry call.
Supported decision
Do the declared local files pass the exact checks required before this replay starts?
Use it when a run should stop before execution because a required authority is missing, a file identity changed, a directory manifest differs, a discovery count falls outside policy, or the declared byte envelope is exceeded.
Fast fit check
Four questions before you buy.
Can readiness be declared?
You must name the authorities, inputs, optional hashes, discovery rules, and resource ceilings in JSON.
Is mechanical evidence enough?
The result says whether declared checks passed; it does not validate meaning, independence, or completeness.
Will another system execute?
This tool stops at the preflight record. Your reviewed workflow decides whether and how a replay runs.
READY / REVIEW / BLOCKED runtimeInspect contract rules, decision exits, release files, test coverage, and support.
Licensed runtime
Preflight, then verify the pack.
python -m replay_input_preflight preflight contract.json --out readiness-pack
python -m replay_input_preflight verify readiness-packpreflight exits 0 for READY, 2 for REVIEW, 3 for BLOCKED, and 1 for invalid input or operation.

Request to buy
Send five non-sensitive facts. Keep the real inputs local.
Include the purchasing legal entity, billing contact, country, Python version, and approximate declared file count plus largest file size. A request is not an accepted order and starts no delivery clock.
