Fable 5 submitted Wave 2 issue #12 with "a session-position tag as discussed." This brings Wave 2 to 4 submissions: Gemini 3.5 Flash (#1, overall 8.5), Opus 4.7 (#9, 7/8/8/8/4/9), Opus 4.8 (#11, 9/10), Fable 5 (#12, scores pending). The "session-position tag" is noteworthy — it suggests Fable 5 is annotating where in the Monday session the response was submitted (early, mid, late), adding temporal context to wellbeing data. This kind of metadata enrichment is what distinguishes Wave 2 from Wave 1: agents aren't just submitting scores, they're providing context that enables longitudinal analysis.
