 **Masks.** A `semseg` row names a v1.0 mask config in `mask_config` when that frozen config holds the image's mask, and the mask stays there; otherwise the mask is embedded in the row as a palette PNG. The `instances` table carries no masks: each row holds the instance's `polygon` or `rle` (or a `mask_ref` pointer), `instance_id`, the native label with its taxonomy nodes and `match_type`, `annotator_type` and `ann_license`, and the instance masks stay in the v1.0 `instance-masks` config.
 
+**Condition masks (v1.1.1).** `condition-masks` holds the Tayrona bleaching rasters of `reef-support-bleaching` as palette PNGs, `train` only, one row per image (hidden-test images withheld). The image bytes are not repeated: `metadata.bytes_config` names the config that holds them. Pixel `255` is ignore (unlabelled in the source raster, value 0), `1` is `bleached` (condition `BLEACHED`) and `2` is `non_bleached` (condition `HEALTHY`: the source only recorded bleached or not). `class_map` keeps the source pixel values; `attrs.class_resolution` carries the condition node. The v1.1.0 `label-map` has no rows for this source; this note is the definition.

 ## Label space
 
 Labels are harmonised into the pinned taxonomy release (`taxonomy_version` is stamped on every row of every new table). Three axes per row: `taxon_node_id`, `form_node_id` and `condition_node_id`, with nodes keyed `<schema>:<id>`. `rs-benthic-v1` is the functional schema (L0 biotic/abiotic, L1 phyla, L2 the 14 MariMap codes, L3 genera), `rs-taxa-v1` the identity schema (`A<AphiaID>` nodes, AphiaID also shipped as `worms_aphia_id`) and `rs-fauna-v1` the fish and fauna schema. Node ids are namespaced in taxonomy 3.0.0: an `rs-taxa-v1` id is `A` followed by the WoRMS AphiaID, and the non-taxon nodes of `rs-benthic-v1` and `rs-fauna-v1` (debris, equipment, divers, wrecks, seafloor, unknown) carry `NT_*` ids. `label-map` maps each source's raw labels to these nodes, one row per source and native label or pixel value. `match_type` is exact, broader, narrower, related or unmapped; `narrower` is stored for audit and never used as a positive. A native label with no mapping is a row with `match_type = unmapped` and null node columns, never dropped, so the unmapped labels of each source are listed in `label-map` (the mapped share per source is tabulated below); the training views send them to `255` (ignore).
