The v14 lilac field guide reverses the network codes supported by v13 bloom records and the 2015 paper

We tested the network labels in two public US lilac and honeysuckle workbooks. The v14 field guide assigns code 7 to Western and code 8 to Eastern. Table 1 of the 2015 data paper gives the reverse map. All 15,370 network-specific lilac first-bloom descriptions in the v13 observations agree with the paper. The pattern holds in early and late records for both programs. The two maps assign opposite labels to 108,852 historical rows at 2,027 sites. This is a source-specific metadata conflict, not evidence that all downstream analyses used the wrong map. We supply a checked code map, a full audit evidence table, source hashes, code, counts, and a figure. We do not estimate climate or pollution effects, event-date error, or observation delay. Later source revisions and other repositories were not tested.
