The parity rule from ui/PLAN.md says every UI phase that decodes a
new Report field must extend the legacy converter in lockstep.
Phase 19 brings ship groups (LocalGroup / OtherGroup /
UnidentifiedGroup / IncomingGroup) and LocalFleet onto the wire-
compatible UI surface; this commit teaches
tools/local-dev/legacy-report to populate the three sections that
exist in the legacy text format:
- "Your Groups" → []LocalGroup. Cargo type, load, fleet name,
state, on-planet vs hyperspace position (origin / range) all
decoded; LocalGroup.ID is synthesised deterministically from
the per-report group index so re-running the converter
produces byte-identical JSON. Speed is left zero — the legacy
table doesn't expose it.
- "Your Fleets" → []LocalFleet. Origin / range / state mirror
the row layout used by Killer / Tancordia variants; gplus's
state-less rows still resolve.
- "Incoming Groups" → []IncomingGroup. Origin / destination
names — and `#NN` by-id references — resolve against the
parsed planet tables. Because the section can land before
"Your Planets" in some engines, group / fleet / incoming rows
are buffered and resolved in `parser.finish` after every
planet is known.
Battles, OtherGroup (only ever in battle rosters), and
UnidentifiedGroup stay out of scope — README.md spells out what
remains not-derivable.
Adds Killer031–033 / TSERCON_Z032–033 / Tancordia036–039 fixtures
to the dg directory and exercises three of them through new
TestParseDg{Killer031,Tancordia037,KNNTS041} smoke tests, plus
inline tests for each new section parser. Drops the stale
KNNTS039.json artefact left over from Phase 18 development.
