Engine wire change: Report.battle switched from []uuid.UUID to
[]BattleSummary{id, planet, shots} so the map can place battle
markers without N extra fetches. FBS schema + generated Go/TS
regenerated; transcoder + report controller updated; openapi
adds the BattleSummary schema with a freeze test.
Backend gateway forwards engine GET /api/v1/battle/:turn/:uuid as
/api/v1/user/games/{game_id}/battles/{turn}/{battle_id} (handler
plus engineclient.FetchBattle, contract test stub, openapi spec).
UI:
- BattleViewer (lib/battle-player/) is a logically isolated SVG
radial scene that consumes a BattleReport prop. Planet at the
centre, races on the outer ring at equal angular spacing, race
clusters by (race, className) with <class>:<numLeft> labels;
observer groups (inBattle: false) are not drawn; eliminated
races drop out and survivors re-distribute on the next frame.
- Shot line per frame: red on destroyed, green otherwise; erased
on the next frame. Playback controls: play/pause + step ± +
rewind + 1x/2x/4x speed (400/200/100 ms per frame).
- Page wrapper (lib/active-view/battle.svelte) loads BattleReport
via api/battle-fetch.ts; synthetic-gameId prefix routes to a
fixture loader, otherwise REST through the gateway. Always-
visible <ol> text protocol satisfies the accessibility ask.
- section-battles.svelte links every battle UUID into the viewer.
- map/battle-markers.ts: yellow X cross of 2 LinePrim through the
corners of the planet's circumscribed square (stroke width
clamps from 1 px at 1 shot to 5 px at 100+ shots); bombing
marker is a stroke-only ring (yellow when damaged, red when
wiped). Wired into state-binding.ts; click handler dispatches
battle clicks to the viewer and bombing clicks to the matching
Reports row.
- i18n keys for the viewer in en + ru.
Docs: ui/docs/battle-viewer-ux.md, FUNCTIONAL.md §6.5 + ru
mirror, ui/PLAN.md Phase 27 decisions + deferred TODOs (push
event, richer class visuals, animated re-distribution).
Tests: Vitest unit (radial layout + timeline frame builder +
marker stroke formula + marker primitives), Playwright e2e for
the viewer (Reports link → viewer, playback step, not-found),
backend engineclient FetchBattle (200 / 404 / bad input), engine
openapi freezes (BattleReport, BattleReportGroup,
BattleActionReport, BattleSummary, Report.battle items).

Replaces the Phase 10 report stub with a scrollable orchestrator that
renders every FBS array as a dedicated section (galaxy summary, votes,
player status, my/foreign sciences, my/foreign ship classes, battles,
bombings, approaching groups, my/foreign/uninhabited/unknown planets,
ships in production, cargo routes, my fleets, my/foreign/unidentified
ship groups). A sticky table of contents (a <select> on mobile),
"back to map" affordance, IntersectionObserver-driven active-section
highlight, and SvelteKit Snapshot-based scroll save/restore round out
the view.
GameReport gains six new fields (players, otherScience, otherShipClass,
battleIds, bombings, shipProductions); decodeReport, the synthetic-
report loader, the e2e fixture builder, and EMPTY_SHIP_GROUPS extend
in lockstep. ~90 new i18n keys land in en + ru together.
The legacy-report parser is extended to populate the new sections from
the dg/gplus text formats (Your Sciences, <Race> Sciences, <Race> Ship
Types, Bombings, Ships In Production). Ships-in-production prod_used
is derived through a new pkg/calc.ShipBuildCost helper; the engine's
controller.ProduceShip refactors to call the same helper without any
behaviour change (engine tests stay unchanged and green). Battles
remain in the parser's Skipped list — the legacy text carries no
stable per-battle UUID.

Adds the Races View in the in-game shell. The table lists every
non-extinct other race with tech levels (percent), totals,
planets, votes received, and a per-row WAR | PEACE segmented
control. A single vote-recipient slot above the table queues a
`CommandRaceVote`; per-row buttons queue `CommandRaceRelation`.
Both commands flow through the existing order draft store with
collapse-by-acceptor (stance) and singleton (vote) rules.
`GameReport` widens with `races`, `myVotes`, `myVoteFor`; the
decoder walks `report.player[]` once for the richer projection.
The optimistic overlay flips stance and vote target immediately;
`votesReceived`, `myVotes`, and the alliance summary stay
server-authoritative — alliance grouping and the 2/3 victory
check are tallied on the server at turn cutoff and explicitly
not surfaced client-side (`rules.txt` keeps foreign races'
outgoing vote targets private).
Includes Vitest component coverage of stance and vote
collapse rules + a Playwright e2e that drives both commands
through the dispatcher route and verifies the gateway saw the
expected `CommandRaceRelation` / `CommandRaceVote` payloads.

Lights up the player-defined sciences feature: a table view with sort
and filter, a designer with four percent inputs and a strict
sum-equals-100 gate, and a Research-sub-row integration so the
planet production picker lists the user's sciences alongside the
four tech buttons. Phase 21 decisions are baked back into ui/PLAN.md
(no UpdateScience on the wire — write-once via createScience +
removeScience; percentages instead of fractions; sciences live under
the existing Research segment).

Send joins Modernize / Dismantle / Transfer as a lockable command:
once any of the four lands in the draft for a group, every action
button on its inspector is disabled with a "command pending"
tooltip and the banner names the queued kind. Load / Unload /
Split / Join Fleet stay non-locking — they stack legitimately on
the engine side.
Two dashed overlays now run alongside the cargo-route arrows:
- Yellow dashed track for own in-space groups, drawn from the
origin planet to the destination (matches the in-space point
colour so eye reads both as one entity).
- Green dashed track for every wire-valid sendShipGroup command
in the order draft, drawn from the source group's orbit planet
to the chosen destination. Disappears when the command is
removed from the order tab, when the engine rejects it, or
when the group has left orbit (in-space track replaces it).
Both tracks are wrap-aware via torusShortestDelta and never
participate in hit-test.
