A straight line from model call to audit response.Three steps. One evidence trail.
Plumbline gives regulated-vertical teams a way to follow a decision from the moment it is made to the moment someone needs to defend it. Start at the call site, keep the record intact as the system changes, and make the answer replayable for risk, audit, and counsel.
Walkthrough · three moves
The trail stays straight when the stakes rise.
Each step answers a different buyer question: where did the evidence begin, can we trust the record as the system changed, and can we show our work when an auditor or incident lead asks for the decision back?
§01a · Plain-English guide
Explain this simply.
Plumbline is designed to fit the way regulated teams already work: one lightweight connection, one durable record, and one replay path for the people accountable for the outcome.
STEP 01 · CONNECT
Put the SDK where decisions happen.
Connect the lightweight SDK to a model or agent pipeline without moving the work into a separate governance workflow.
Capture the decision context at the call site: the model or agent version, relevant inputs, output, and the review boundary your team needs to keep visible.
STEP 02 · CAPTURE
Keep every evaluation run tied to its evidence.
Capture versioned evaluation runs, signed records, and drift ledgers as the system changes over time.
The record preserves what was tested, what changed, and what was signed. Drift signals sit beside the same chain instead of disappearing into a separate dashboard or spreadsheet.
STEP 03 · REPLAY
Defend the decision when the question arrives.
Replay the path from decision to evidence when audit, incident response, or counsel needs a clear answer.
Open the signed record, verify its chain, and hand the right audience a defensible explanation of what happened — without reconstructing the story from memory.
Keep going
The technical layer is there for inspection; the buyer-facing story stays simple enough to use in a risk review.
