- Gold article added as reference standard in STEP4_MASTER_DRAFT
- MANDATORY SECTIONS removed — replaced with continuous prose requirement
- STEP3_OUTLINE: now a flow plan (3-4 beats), not a section list
- STEP5_REALITY_INJECTION: no longer adds 'What Breaks' sections — injects into prose
- STEP9_QA_CHECK: format violations now primary HARD FAIL, above content checks
- DR4 wavelength fix: 1310nm = 0.35 dB/km (not 1550nm = 0.22 dB/km)
- Scope description fix: visual inspection tool ≠ loss measurement device
- Invented firmware version numbers now explicit HARD FAIL
