open-questions.md buries live OQs under ~23.5 kB of resolved inline analysis #165

Severity: Low (process debt). Review finding D19; deferred by #157. Re-verified at 1c4e71e.

In docs/planning/open-questions.md, 10 table rows exceed 2 kB (34,285 characters in total; the longest is 5,707):

• 6 are RESOLVED mega-rows, about 23.5 kB of inline resolved analysis: OQ-27 (4,509), OQ-28 (2,239), OQ-29 (4,891), OQ-30 (5,707), OQ-31 (2,337), OQ-32 (3,871).
• 4 live or unmarked rows of 2.1–3.2 kB: OQ-33 to OQ-36.

The live questions are buried among closed ones.

Reproduce: use Python to count table rows longer than 2,000 characters.

Fix: move resolved analyses into per-OQ files (the repo already does this for spikes) and leave a one-line resolution plus a pointer in the table.
