close bucket 0

B8 done, so every defect that made opencode behave wrongly is fixed. Notes what that does
not mean: bucket 1 is capability gaps, and the visible ones are downstream of the phase 2
fork, which is still unstarted and still Andre to call.

 Also fixed after the review, and not in this table because it was found by reviewing the fix for B5/B6:
 a superseded OpenCode turn ran its whole completion path against the turn that replaced it. See
