Adds the gear-icon popover on the map view with per-game persistence
of every category toggle plus the wrap-mode radio. Hide-by-id and
visibility-fog facilities land on the renderer so every flip applies
within one frame without a Pixi remount; the wrap-mode toggle keeps
its existing remount + camera-preserve path. A new server-side turn
force-resets every flag to defaults so a hidden category never makes
the player miss the next turn's news.
Also fixes the FligthDistance → FlightDistance typo in pkg/calc/race.go
(plus the single Go caller); the TS side keeps duplicating the formula
until a race-level WASM bridge lands.

Browser fetch-streaming layers close response bodies they consider
idle after roughly 15-30 s without incoming bytes. Safari is the
most aggressive, but the symptom matters everywhere: a quiet
SubscribeEvents stream (lobby, between turns, mailbox empty) gets
torn down by the browser, the EventStream singleton reconnects with
backoff, and any push event that fires inside the reconnect window
is lost because `push.Hub` queues are not persisted across
subscription closes. The user-visible failure mode is the
intermittent "Fetch API cannot load … due to access control checks"
console error (a misleading WebKit symptom — CORS headers are
actually present) plus missed turn-ready / mail-received toasts.
Server-side fix: a silence-based heartbeat at the
`authenticatedPushStreamService` wrapper layer. After the signed
`gateway.server_time` bootstrap event, gateway wraps the bound
stream with `heartbeatingStream`. Every tail Send (fan-out, future
variants) resets the silence timer; when the timer elapses, a
goroutine emits `gateway.heartbeat` with only `EventType` set —
everything else stays at proto3 defaults, so the wire frame is
~45 bytes amortised. A `sendMu` serialises the heartbeat goroutine
with tail Sends because grpc.ServerStream.Send is not goroutine-safe.
The heartbeat is intentionally UNSIGNED: heartbeats carry no
payload, dispatch to no handler on the client, and an injected
heartbeat trivially causes no user-visible state change. TLS still
protects the wire and real events keep the signed envelope
unchanged. Documented in `docs/ARCHITECTURE.md` § 15 alongside the
per-scale bandwidth projection (100…100 000 clients × 15…60 s).
Config: new `GATEWAY_PUSH_HEARTBEAT_INTERVAL` (default `15s`,
`0s` disables). Telemetry: new
`gateway.push.heartbeats_sent{outcome}` counter so operators can
budget bandwidth and spot a sudden `outcome=error` bump as an
upstream-failing-before-flush signal.
Client (`ui/frontend/src/api/events.svelte.ts`): early `continue`
on `event.eventType === "gateway.heartbeat"` before `verifyEvent`,
`verifyPayloadHash`, or dispatch — empty signature would otherwise
trip SignatureError and reconnect. A leading heartbeat still flips
`connectionStatus` to `connected` and resets backoff, because
receiving one is proof the stream is healthy.
Tests:
- `push_heartbeat_test.go`: unit tests for the wrapper — zero
interval returns nil, heartbeat fires after silence, real Send
resets the timer, Stop / context-cancel halt the goroutine,
Send errors propagate.
- `server_test.go`: integration tests through the full gateway
pipeline — heartbeat fires after the configured silence window,
zero interval keeps the stream silent.
- `config_test.go`: default applied, env-override parsed,
negative value rejected.
- `events.test.ts`: heartbeat skipped before verification + not
dispatched to handlers; leading heartbeat still flips
`connectionStatus` to `connected`.

The Phase 28 ConnectRPC migration of the battle viewer added a
guard in `lib/active-view/battle.svelte` that waits for the
surrounding layout to publish a `GalaxyClient` before issuing the
fetch. The in-game shell layout deliberately skips
`galaxyClient.set(...)` on the synthetic branch (gateway is not
reachable in synthetic mode), so for any battle opened from a
synthetic-report game the viewer sat on "loading battle…"
forever — `fetchBattle` was never called, so the synthetic-fixture
short-circuit it carries was unreachable.
Let the guard skip synthetic ids: `fetchBattle` already resolves
those through `lookupSyntheticBattle` and never touches the
client, so its signature widens to `GalaxyClient | null` and the
synthetic path passes `null`. The live path still waits for the
handle as before; a `null` client on the live path now fails
fast with a transport-level `BattleFetchError` instead of silently
sitting on `loading`.
Tests:
- Existing "loading placeholder" smoke now uses a non-synthetic
game id so it keeps asserting the live-path wait.
- Two new cases pin the synthetic behaviour: missing fixture →
`battle-not-found`; registered fixture → `BattleViewer` mounts.
Docs:
- `docs/FUNCTIONAL.md` §6.5 still described the pre-Phase-28
raw REST path. Updated to the signed ConnectRPC command and
noted the synthetic short-circuit. Russian mirror updated.

Closes the documentation gaps from the freshly-audited diplomail
implementation. FUNCTIONAL.md gains a §11 "Diplomatic mail" with
the full user-facing story across all five stages, mirrored into
FUNCTIONAL_ru.md as the project conventions require. A new
backend/docs/diplomail-translator-setup.md captures the
LibreTranslate operational recipe (Docker image, env wiring,
manual smoke test, troubleshooting). The package README gains a
"Multi-instance posture" note documenting the deliberate absence
of FOR UPDATE in the worker pickup query — single-instance is
safe today; multi-instance scaling will revisit the claim
mechanism.
Two small edge-case tests round things out: malformed
LibreTranslate response bodies (single string, short array,
empty array, missing field) must surface as errors so the worker
falls back instead of crashing; and an empty translation queue
must produce zero events on three consecutive Worker.Tick calls.

Three Phase-27 BattleViewer refinements on top of the radial scene:
1. Height fit. The viewer is pinned to `calc(100dvh − 80px)` so it
never pushes the in-game shell past the viewport. `.active-view`
gains `overflow: hidden` + flex column; `.viewer` becomes a
`flex: 1` child; the always-visible text log shrinks to a 30 dvh
ceiling with its own scroll. A global `body { margin: 0 }`
reset (added to `app.html`) plugs the 16 px the browser's
default body margin used to leak.
2. Mass-based ship-class circles. New `lib/battle-player/mass.ts`
carries the radius formula and the per-battle FullMass compute:
`MIN_RADIUS + (MAX_RADIUS − MIN_RADIUS) * sqrt(mass / max)`,
clamped to `[6, 24] px`. FullMass goes through the existing
wasm bridge (`emptyMass` → `carryingMass` → `fullMass`) — no
new wire fields. The viewer page resolves a
`(race, className) → ShipClassRef` lookup from the parent
GameReport's `localShipClass` + `otherShipClass` tables and
passes it to the viewer via context. Unknown class or
degenerate (weapons/armament) params fall back to MAX_RADIUS
so the bucket stays visible.
3. Cloud cluster layout. Cluster key shifts from per-group
`g.key` to `(raceId, className)` so tech-variants of the same
hull collapse into one visual bucket. The horizontal
classCircleX row is replaced by a Vogel sunflower spiral in
the local `(u, v)` basis — `u` points from the race anchor to
the planet, `v` is `u` rotated 90° clockwise. Buckets are
sorted by NumberLeft desc; the cluster anchor is pushed inward
by a quarter step so rank-0 sits closest to the planet. The
step is adaptive (`min(baseStep, MAX_CLUSTER_RADIUS / sqrt(N))`)
so clusters with many classes do not spill into neighbours.
Tests:
- Vitest: `radiusForMass` covering zero / max / quarter-mass /
out-of-range cases (6 cases).
- Playwright: new `battle-viewer.spec.ts` case asserts
`document.documentElement.scrollHeight - window.innerHeight ≤ 4`
at a 1280×720 desktop viewport. The existing fixture gains
`localShipClass` + `otherShipClass` so the lookup has data to
render proportional circles.
Docs: `ui/docs/battle-viewer-ux.md` rewrites the "Radial scene"
section (cloud layout, mass-based radius, height fit) and adds
a "Height fit" subsection. `docs/FUNCTIONAL.md` §6.5 (+ ru
mirror) get the one-line story about per-mass sizing, cluster
aggregation, and the viewport-locked layout.

Side activity on top of Phase 27: the legacy-report tool now extracts
the "Battle at (#N) Name" / "Battle Protocol" blocks the parser used
to skip. Both the per-battle summary (Report.Battle: []BattleSummary)
and the full BattleReport (rosters + protocol) flow through.
Parser:
- new sectionBattle / sectionBattleProtocol states, with handle()
trapping the per-race "<Race> Groups" sub-headers so the roster
stays attributed to the right race;
- parseBattleHeader extracts (planet, planetName) from
"Battle at (#NN) <Name>";
- parseBattleRosterRow maps the 10-token row into
BattleReportGroup; column 8 ("L") is NumberLeft, confirmed against
KNNTS fixtures;
- parseBattleProtocolLine counts shots and builds
BattleActionReport entries from the 8-token "X Y fires on A B :
Destroyed|Shields" lines;
- flushPendingBattle finalises a battle on next "Battle at" or any
top-level section change and appends both the summary and the
full report;
- syntheticBattleID(idx) + syntheticBattleRaceID(name) synthesise
stable UUIDs in dedicated namespaces so re-runs produce
byte-identical JSON.
Parse() signature widens to (Report, []BattleReport, error); the
single caller — the CLI — is updated.
CLI emits a v1 envelope:
{ "version": 1, "report": <Report>, "battles": { <uuid>: <BR>, ... } }
Bare-Report JSONs still load on the UI side for backward compat.
UI synthetic loader: loadSyntheticReportFromJSON detects the v1
envelope, decodes the report as before, and forwards every battle
through registerSyntheticBattle so the Battle Viewer resolves any
UUID offline. Pre-envelope JSON files (no `version` field) still
load — the battle registry stays empty for them.
Docs: legacy-report README moves Battles from "Skipped" to
in-scope, documents the envelope and UUID namespaces;
docs/FUNCTIONAL.md §6.5 (and the ru mirror) note that synthetic
mode is now end-to-end via the envelope.
Tests:
- TestParseBattles covers two battles with full rosters,
per-shot destroyed/shielded mapping, NumberLeft from column 8,
deterministic UUIDs across re-parses, and proves a trailing
top-level section still parses (battle state closes cleanly);
- smokeWant gains a battles count; runSmoke cross-checks
BattleSummary ↔ BattleReport alignment (id/planet/shots);
- all six real-fixture smoke tests pinned to their `Battle at`
counts (28, 79, 56, 30, 83, 57);
- Vitest covers the synthetic-report envelope path (battles
forwarded, missing-battles tolerated, bare-Report backward
compat);
- KNNTS041.json regenerated against the new parser (existing
diff was stale w.r.t. Phase 23 anyway; this commit brings it
in line with the v1 envelope).

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).

Backend now owns the turn-cutoff and pause guards the order tab
relies on: the scheduler flips runtime_status between
generation_in_progress and running around every engine tick, a
failed tick auto-pauses the game through OnRuntimeSnapshot, and a
new game.paused notification kind fans out alongside
game.turn.ready. The user-games handlers reject submits with
HTTP 409 turn_already_closed or game_paused depending on the
runtime state.
UI delegates auto-sync to a new OrderQueue: offline detection,
single retry on reconnect, conflict / paused classification.
OrderDraftStore surfaces conflictBanner / pausedBanner runes,
clears them on local mutation or on a game.turn.ready push via
resetForNewTurn. The order tab renders the matching banners and
the new conflict per-row badge; i18n bundles cover en + ru.

Wires the gateway's signed SubscribeEvents stream end-to-end:
- backend: emit game.turn.ready from lobby.OnRuntimeSnapshot on every
current_turn advance, addressed to every active membership, push-only
channel, idempotency key turn-ready:<game_id>:<turn>;
- ui: single EventStream singleton replaces revocation-watcher.ts and
carries both per-event dispatch and revocation detection; toast
primitive (store + host) lives in lib/; GameStateStore gains
pendingTurn/markPendingTurn/advanceToPending and a persisted
lastViewedTurn so a return after multiple turns surfaces the same
"view now" affordance as a live push event;
- mandatory event-signature verification through ui/core
(verifyPayloadHash + verifyEvent), full-jitter exponential backoff
1s -> 30s on transient failure, signOut("revoked") on
Unauthenticated or clean end-of-stream;
- catalog and migration accept the new kind; tests cover producer
(testcontainers + capturing publisher), consumer (Vitest event
stream, toast, game-state extensions), and a Playwright e2e
delivering a signed frame to the live UI.

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.

Wires the first end-to-end command through the full pipeline:
inspector rename action → local order draft → user.games.order
submit → optimistic overlay on map / inspector → server hydration
on cache miss via the new user.games.order.get message type.
Backend: GET /api/v1/user/games/{id}/orders forwards to engine
GET /api/v1/order. Gateway parses the engine PUT response into the
extended UserGamesOrderResponse FBS envelope and adds
executeUserGamesOrderGet for the read-back path. Frontend ports
ValidateTypeName to TS, lands the inline rename editor + Submit
button, and exposes a renderedReport context so consumers see the
overlay-applied snapshot.

Adds a minimal Svelte 5 i18n primitive (`src/lib/i18n/`) backing the
login form, the layout blocker page, and the lobby placeholder.
SUPPORTED_LOCALES drives both the picker and the runtime lookup;
adding a language is a two-step change inside `src/lib/i18n/`.
Login form gains a globe-icon language dropdown (English / Русский
in their native names), defaulting to navigator.languages with `en`
as the fallback. Switching the locale re-renders the form in place;
on submit, the locale rides in the JSON body of `send-email-code`
because Safari/WebKit silently drops JS-set Accept-Language. Gateway
gains a body `locale` field that takes priority over the request
header for preferred-language resolution.
Email and code inputs disable browser autofill / suggestions
(`autocomplete=off` + `autocorrect=off` + `autocapitalize=off` +
`spellcheck=false`) so Keychain / address-book pickers and
remembered-value dropdowns no longer fire on focus.
Cross-cuts:
- backend & gateway openapi: clarify that body `locale` is honored.
- docs/FUNCTIONAL{,_ru}.md §1.2: document body-vs-header priority.
- gateway tests: body `locale` overrides Accept-Language; blank
body `locale` falls back to header.
- new ui/docs/i18n.md; cross-links from auth-flow.md and ui/README.

Replace the native-gRPC server bootstrap with a single
`connectrpc.com/connect` HTTP/h2c listener. Connect-Go natively
serves Connect, gRPC, and gRPC-Web on the same port, so browsers can
now reach the authenticated surface without giving up the gRPC
framing native and desktop clients may use later. The decorator
stack (envelope → session → payload-hash → signature →
freshness/replay → rate-limit → routing/push) is reused unchanged
behind a small Connect → gRPC adapter and a `grpc.ServerStream`
shim around `*connect.ServerStream`.
