Overview

Parses various reference forms into an ItemId model.

Supported formats:

- Full:    "8pp.t.q7w"    → prefix=8pp, marker=t, suffix=q7w
- Short:   "t.q7w"        → prefix=nil, marker=t, suffix=q7w
- Suffix:  "q7w"          → prefix=nil, marker=nil, suffix=q7w
- Subtask: "8pp.t.q7w.a"  → prefix=8pp, marker=t, suffix=q7w, subtask=a
- Raw:     "8ppq7w"       → prefix=8pp, marker=nil, suffix=q7w (6-char raw b36ts)

Constant Summary collapse

FULL_PATTERN =

Full format: prefix.marker.suffix (e.g., “8pp.t.q7w”)

/^([0-9a-z]{3})\.([a-z])\.([0-9a-z]{3})$/
SUBTASK_PATTERN =

Full with subtask: prefix.marker.suffix.subtask (e.g., “8pp.t.q7w.a”)

/^([0-9a-z]{3})\.([a-z])\.([0-9a-z]{3})\.([0-9a-z])$/
SHORT_PATTERN =

Short format: marker.suffix (e.g., “t.q7w”)

/^([a-z])\.([0-9a-z]{3})$/
SUFFIX_PATTERN =

Suffix-only: 3 chars (e.g., “q7w”)

/^[0-9a-z]{3}$/
RAW_PATTERN =

Raw 6-char b36ts (e.g., “8ppq7w”)

/^[0-9a-z]{6}$/
