docs(phase2): coverage gate, migration TODOs, session handoff

- add tools/check_coverage.py and .audit/coverage ledger (schema + settings pilot)
- add coverage gap worklist and source-doc migration TODOs
- add session handoff; redirect stale resume points in AGENTS.md, docs/README.md, reconciliation record
- add rows: CAPTURE-41, CAPTURE-141, METADATA-66, PUBLISH-31, SETTINGS-51

 | CAPTURE-35 | Sheet detection samples a 2 to 5 percent strip on all four borders and classifies green or black by HSV; otherwise the owner picks the sheet. | shipped | frontend/src/mask/sheetKeep.test.ts |
 | CAPTURE-40 | Mask controls are exactly Sheet (auto, green, black) and Sensitivity (0 to 100, step 1); Edge offset and Feather are removed. | shipped | — |
+| CAPTURE-41 | Sensitivity 0 to 100 maps to green-sheet chroma tightness and black-sheet brightness cutoff in the worker; both widen as sensitivity rises. | shipped | frontend/src/mask/sheetKeep.test.ts |
 | CAPTURE-45 | A Sensitivity change debounces 2000 ms; a Sheet change runs immediately; the overlay recomputes in a worker and the last good overlay stays visible. | shipped | frontend/src/capture/session.calibrate.test.ts |

 | CAPTURE-130 | The photos-ready lineup order is clean calibration PNG, dimension-overlay copy, then remaining batch photos in capture order. | shipped | frontend/src/capture/photosReadyLineup.test.ts |
 | CAPTURE-135 | The client computes all deterministic math; the server stores the client numbers and never recomputes them as source of truth. | shipped | — |
 | CAPTURE-140 | Load-bearing client APIs are image decode, canvas or OffscreenCanvas, a worker, PNG encode, IndexedDB, and fetch; no OpenCV, ONNX, or U2Net on the shipped path. | shipped | — |
+| CAPTURE-141 | The preview is display-only: it fits the device width with a height cap so controls stay visible, and mask, rectangle, crop, scale, sqft, and PNG encode use source photo pixels, never the preview's CSS size. | shipped | frontend/src/capture/fitDisplay.test.ts |

 | CAPTURE-150 | Mask tuning has no apply step and no server round trip. | shipped | — |
 | CAPTURE-155 | Failures such as a broken mask or undersized source never silently guess; the resolution is retake. | shipped | — |

 | METADATA-60 | Call 2 receives all metadata confirmed or changed in review plus the literal dimension fact block; the template guides style and the model has creative license. | M3 | — |
