Top-Band Source Evidence Completion Bridge
A low-risk abstain became a source-backed, caveated fallback by using the attached JD context instead of title-only repair.
This slice fixed one remaining top-band runtime abstain without using an LLM or live embedding call. The title ai content writer was blocked because existing snippets were too thin, but the LinkedIn JD rows already contained clean responsibility evidence.
Source Completion And Bridge
Two new lanes were added. top_band_source_evidence_completion_v1 reads only low-risk source-authority incomplete abstains and derives clean snippets from existing JD rows. top_band_source_evidence_contract_bridge_v1 consumes only completion-pass rows and emits caveated fallback contracts.
The JD Was Useful
The completed row is ai content writer, rank 413, top band top_500, function marketing. Clean snippets include chatbot conversations, prompt-answer writing, model comparison, and fact-checking. Benefits, paid hourly text, PayPal/payment text, and schedule artifacts were filtered out.
| Persisted Signal | Why It Matters |
|---|---|
| Compare AI model performance | Supports evaluator and workflow realism. |
| Research and fact-check AI responses | Maps directly to judgment quality. |
| Write prompt-based answers | Supports content-production practice tasks. |
One Less Abstain
The row moved from abstain to fallback, not full serve. That is the right production posture because source evidence is now stronger, but full runtime service authority is still not claimed.

Still Local And Safe
Sensitive Rows Need A Stricter Lane
The remaining 25 abstains are risk-tagged or confirmation-blocked. The next move is a sensitive-role source-authority lane grouped by risk bucket, with evaluator guardrails before any fallback bridge. case manager should remain held until subtype or learner/source confirmation exists.
Resume by inspecting the 25-row repair queue, then design the stricter sensitive-role bridge rather than promoting those rows by title alone.
