Dependencies

• [2] GE3VNRXL ck 2
• [3] LQLC7S3A trying gemini: Inconsistent Standards in @utils/ refactoring
• [4] KZKLAINJ run out of space on nest, cleaned out
• [5] 2HAQZPV3 more refactoring with glm
• [6] 2P27XV3D fixed cyclo over 30
• [7] DS22DKV3 added shell script integration tests.
• [*] JZRF7OBJ refactor to get db omports out of utils, but still have failing tests, may need updating

  + ### Complexity reductions (Stream 6)

  +

  + **tui.Model.View** (14→7): Extracted `renderHeader`, `renderProgressBar`,

  + `renderSegmentInfo`, and `renderLabels` helper methods from the monolithic

  + View function.

  +

  + **utils/normalizeFlat** (14→6): Extracted `convertToDB` helper that finds

  + minNonZero, converts power values to dB in-place, and returns min/max dB.
• edit in CHANGELOG.md at line 91
  [2.8674]

  [9.7568]
  + **utils/collectMappedLabels** (13→8): Extracted `collectUnmappedCalltypes`

  + helper that adds calltypes from .data files with no explicit mapping entry.
