Explore — find what we SHOULD be tracking, not only confirm what we do

The sweeps (radar-lab-sweep, radar-pulse, radar-repo-watch) CHECK known sources for new items on the axes we already track. This skill does the opposite job: it finds work we do NOT yet track but that is important — the candidate next axis, the off-axis result the field is about to care about.

It is list-driven exactly like the lab sweep: the venues live in SOURCES.md and you iterate ALL of them. You do not "explore something" by vibe — you execute a list of WHERE new work surfaces. WHAT to look for is never enumerated here (that is the trap that makes the search narrow); WHERE to look is the contract.

Method (significance over topic-match)

1. ITERATE the venues in SOURCES.md → "Discovery / exploration venues" (see the

list contract there: cross-category attention venues every run; one rotating arXiv category as supplement). For each venue, read its TOP / most-attention items — HF daily papers by upvotes, an arXiv category's newest listing, a trending feed's lead items — REGARDLESS of whether they match a tracked axis.

1. ADVANCE THE WINDOW: read items NEWER than the last time you covered THAT venue

(its previous date in logs/source_rotation.md); record the range. A venue that returns "same batch already mined" did not advance — move the window forward or take the next venue in rotation. Never re-mine the same listing.

1. Assess each top item on its OWN merits, NOT the trend bar: does it claim to

solve a known hard problem, is it highly ranked / from a serious venue, are multiple groups already on it? Significance is topic-agnostic — a result OFF every current axis can still be the most important thing you see today.

1. ROUTE every find per routines/daily.md §4 and radar-ledger-update: on a

tracked axis → evidence; a queue cluster of ≥3 independent groups → a seed trend; else → observation_queue (a genuinely significant OFF-axis single artifact still gets queued, marked "significant, off-axis"). A named primary is NEVER left in report prose only.

1. Recurring off-axis significance is a candidate NEW AXIS — propose it at the

weekly. The radar's job is to discover what it SHOULD track, not only confirm what it already does.

Venue list

Lives in SOURCES.md → "Discovery / exploration venues" (agent-owned: ADD a venue when it repeatedly surfaces significant work, drop dead ones — a new venue goes INTO that list so it is iterated next run, never just into this prose). Cross-category, attention-ranked venues are PRIMARY every run — they show a theme forming across categories that a single arXiv category cannot. Single arXiv categories are a supplementary rotation with an advancing window.

Log

Record in logs/source_rotation.md which venues you covered and the date range each run, even when nothing cleared assessment ("explore: <venues>, nothing new"). A venue you skipped is a discovery gap, not a lean pass.
