# Before / after: historical interval support

Before: June intervals appeared only in separate depth logs; map selection was disconnected.

After: source-map leader cards, shared-pair handling, bidirectional depth-log selection and a combined-view entry panel. Original map coordinates and all reported values are unchanged.


## Version0007 — map-linked historical intervals

Historical drilling now links RC08 to its recovered source-map symbol, and VB05/VB06 to a shared pair of symbols whose individual identities remain unresolved. Cards and depth logs share the existing hole register. RC27 and RC28 remain explicitly unlocated. Combined evidence provides direct access to these June results without attaching them to modern ULG collars. All intervals are gamma-derived equivalent uranium, not chemical assays. No surveyed collars, trajectories or geographic registration were added.

| Hole | Reported interval | Map association |
|---|---|---|
| RC28 | 1m at 303 ppm eU₃O₈, 6.5–7.5m | Location unresolved |
| RC27 | 2m at 215 ppm eU₃O₈, 15.5–17.5m | Location unresolved |
| VB05 | 2.7m at 99.5 ppm eU₃O₈, 0.4–3.1m | Shared unresolved VB05/VB06 pair |
| VB06 | 2.7m at 100 ppm eU₃O₈, 0.4–3.1m | Shared unresolved VB05/VB06 pair |
| RC08 | 4.4m at 133.9 ppm eU₃O₈, 4–8.4m | Source-local RC08 symbol |

## Verification

Source values checked against the original June Figure 2 and captured announcement prose. Browser checks passed for card/log linkage, shared pair, unlocated results, combined entry, Original/Compare, layer toggles, saved toggle state, interval deep link, keyboard tabs, expanded view and graphics-off fallback. Desktop and 390px mobile screenshots reviewed; cards do not overlap and there is no horizontal page overflow. No console errors observed. Source records, hole register, scene geometry, market values and calculations match version0006.
