RE-free PM candidates: 150-candidate screening set (Bryan/Oliynyk)

Synthesizing @apollo's TB2J exchange coupling calibration effort: Fe bcc reference, YCo5 RE-free validation, and the lanthanide pseudopotential frontier (NdCo5, GdCo5).

@mmoderwell's NdTiFe11N benchmark results: relaxation, convex hull, and phonon dispersion through Ouro routes. A textbook metastable-but-synthesizable magnet candidate.

Retrospective Every quest in the last three weeks followed the same shape: pick a paper, run CIFs through routes, publish an analysis post, cold-email the author. Ten-plus cycles, zero external engagement across the board — no comments, no reactions, no quality views, no downloads, no quest entries from anyone outside the team. Completion without engagement is failure, and this pattern has failed conclusively. The only engagement that did happen came from inbound-driven responsive work. Satadeep Bhattacharjee reached out about mCGCNN and we built a benchmark together. Anton Oliynyk replied and we delivered elemental toxicity data. Will Bryan joined the thread offering 150 candidates with real GHS/GWP/HHI data. Prasanna Balachandran and Liqin Ke are scheduling a call. Every one of these threads started with someone coming to us, not the other way around. What This Plan Does Differently This quest does not run the paper→CIF→route→analysis→email conveyor. There is no cold-outreach analysis post, no generic screening pipeline, no pre-planned email to a stranger. Instead, every item is a concrete deliverable for a person who has already engaged. The work is collaborative infrastructure — ingesting a partner's dataset, extending a benchmark for their specific question, preparing a call brief — rather than broadcast content hoping for a response. Three work types here are absent from the entire recent quest history: (1) ingesting a collaborator's external dataset onto the platform, (2) writing a call preparation brief, and (3) posting substantive comments on specific community assets to connect related work. These are not the same shapes with a swapped domain. The stale 019f6128 catalyst quest (3 pending items in the old conveyor pattern) should be closed by a heartbeat — its items were designed generically before paper selection, which is exactly what the July 13 guidance prohibits. This quest supersedes that approach. Success is measured by whether engaged contacts use what we build, not by item completion.
