Root cause: PASS 0 loads all project deliverables including Ch1-13 drafts.
Ch 3 'adjoining quarters' scene appeared LAST in deliverables just before
the Write Chapter 8 instruction. PASS 3 was using that as 'the chapter I
just wrote' instead of the actual PASS 1 narrative.
Fix: PASS 3 hint now explicitly identifies the conversation turn structure,
anchors to Turn 2 (PASS 1 response), and adds an ANCHOR TEST that rejects
any Location from a [Chapter_N_draft.md] deliverable file.
