+## ~~Phase 14. First End-to-End Command — Rename Planet~~
 
-Status: pending.
+Status: done.
 
 Goal: prove the entire pipeline (inspector → composer → submit →
 server → state refresh) by wiring up exactly one action: renaming a
 planet.
 
-Artifacts:
+Decisions taken with the project owner during implementation:
 
-- `ui/frontend/src/lib/inspectors/planet.svelte` adds a `Rename` action
+1. **Optimistic overlay over `user.games.order`.** The plan's
-  that opens a small inline editor and adds a `RenamePlanet` command
+   acceptance criterion ("name change within one second") is
-  to the order draft on confirm
+   inconsistent with the engine's order endpoint, which only
-- `ui/frontend/src/sync/submit.ts` `submitOrder()` function that POSTs
+   validates and stores; rename takes effect at turn cutoff.
-  the entire draft via `GalaxyClient.execute('user.games.order', ...)`
+   Phase 14 keeps `user.games.order` for the wire path and adds a
-  and applies per-command results
+   pure projection `applyOrderOverlay(report, commands, statuses)`
-- `ui/frontend/src/lib/sidebar/order-tab.svelte` adds a `Submit order`
+   in `api/game-state.ts`. Inspector, mobile sheet, and map
-  button calling `submitOrder()` and renders accepted / rejected
+   renderer read a derived `renderedReport` (context key
-  status per command after submit
+   `RENDERED_REPORT_CONTEXT_KEY`) that swaps planet names in for
-- on successful submit, refresh game state so the rename appears on the
+   every applied or in-flight rename. Raw `gameState.report`
-  map and in the inspector
+   stays available for debugging / history mode.
+2. **Read-back endpoint `user.games.order.get`.** Without a
+   server snapshot of stored orders the optimistic overlay would
+   not survive a cache wipe. Phase 14 adds the new authenticated
+   message type with a backend route
+   `GET /api/v1/user/games/{game_id}/orders?turn=N` (pass-through
+   to the engine's existing `GET /api/v1/order`). The frontend
+   calls it from `OrderDraftStore.hydrateFromServer` only when
+   the local cache row is *absent* — an explicitly empty cache
+   row honours the user's empty draft. The `turn` query is
+   required (the frontend always knows the current turn from the
+   lobby record).
+3. **Per-command results from real engine response.** The engine
+   now answers `PUT /api/v1/order` with `202 Accepted` and a
+   populated `UserGamesOrder` body (per-command `cmdApplied`,
+   `cmdErrorCode`, plus an engine-assigned `updatedAt`). The
+   gateway parses that JSON into the extended FBS
+   `UserGamesOrderResponse` envelope and the frontend reads the
+   per-command outcome through `submitOrder`. A defensive
+   batch-level fallback covers an empty `commands` array.
+4. **Applied commands stay in the draft.** Per the gameplay
+   model, the order is the player's intent surface — submitted
+   commands stay until the user removes them or until turn
+   cutoff (Phase 24 wires the auto-clear). Statuses are
+   runtime-only; on reload the draft re-validates as `valid` and
+   the overlay re-applies.
+5. **Validator parity through a TS port.** `ValidateTypeName`
+   from `pkg/util/string.go` is mirrored in
+   `ui/frontend/src/lib/util/entity-name.ts`. The inspector's
+   inline editor disables the confirm button until the input
+   passes; the draft store re-runs the validator on every `add`
+   and exposes per-row `valid` / `invalid` to the order tab.
+6. **`updatedAt` plumbing without enforcement.** Phase 14 sends
+   `0` on every submit (no client-side stale-order detection
+   yet); the engine still writes a real timestamp, the gateway
+   surfaces it in the FBS response, and the draft stashes it.
+   Future phases can wire conditional updates without a wire
+   change.
+
+Artifacts (delivered):
+
+- `pkg/schema/fbs/order.fbs` — extended `UserGamesOrderResponse`
+  (`game_id`, `updated_at`, `commands`); new
+  `UserGamesOrderGet` / `UserGamesOrderGetResponse` tables.
+- `pkg/model/order/order.go` — `MessageTypeUserGamesOrderGet` and
+  `UserGamesOrderGet` typed payload.
+- `pkg/transcoder/order.go` — `JSONToUserGamesOrder`,
+  `UserGamesOrderResponseToPayload`,
+  `UserGamesOrderGetToPayload`,
+  `PayloadToUserGamesOrderGet`,
+  `PayloadToUserGamesOrderResponse`,
+  `UserGamesOrderGetResponseToPayload`,
+  `PayloadToUserGamesOrderGetResponse`. Replaces the old
+  `EmptyUserGamesOrderResponsePayload` helper.
+- `backend/internal/server/handlers_user_games.go` — new
+  `GetOrders` handler. `engineclient.GetOrder` forwards to the
+  engine's `GET /api/v1/order` with the player rebound.
+  `backend/openapi.yaml` documents the new GET operation;
+  `contract_test.go` extended with a `queryParamStubs` map for
+  required query parameters.
+- `gateway/internal/backendclient/games_commands.go` — updated
+  `executeUserGamesOrder` (parses real engine JSON via
+  `JSONToUserGamesOrder`); new `executeUserGamesOrderGet` and
+  `projectUserGamesOrderGetResponse`.
+  `gateway/internal/backendclient/routes.go` registers the new
+  message type.
+- `ui/Makefile` — `order.fbs` joins `FBS_INPUTS`; regenerated TS
+  bindings under `ui/frontend/src/proto/galaxy/fbs/order/`.
+- `ui/frontend/src/sync/order-types.ts` — `PlanetRenameCommand`
+  variant added to the discriminated union.
+- `ui/frontend/src/sync/submit.ts` — `submitOrder` posts the FBS
+  request and parses per-command verdicts.
+- `ui/frontend/src/sync/order-load.ts` — `fetchOrder` issues
+  `user.games.order.get`.
+- `ui/frontend/src/sync/order-draft.svelte.ts` — extended with
+  per-command `statuses`, `validate` / `markSubmitting` /
+  `applyResults` / `markRejected` / `revertSubmittingToValid` /
+  `hydrateFromServer`, and the `needsServerHydration` flag.
+- `ui/frontend/src/lib/util/entity-name.ts` — TS port of
+  `ValidateTypeName`.
+- `ui/frontend/src/api/game-state.ts` — pure
+  `applyOrderOverlay(report, commands, statuses)` projection
+  plus the `currentTurn` rune on `GameStateStore`.
+- `ui/frontend/src/lib/rendered-report.svelte.ts` — derives the
+  overlay-applied report and exposes it through
+  `RENDERED_REPORT_CONTEXT_KEY`.
+- `ui/frontend/src/lib/galaxy-client-context.svelte.ts` —
+  `GalaxyClientHolder` so command-driven UI can resolve the
+  per-game `GalaxyClient` via context.
+- `ui/frontend/src/lib/inspectors/planet.svelte` — Rename action
+  + inline editor with `validateEntityName`-driven feedback.
+- `ui/frontend/src/lib/sidebar/order-tab.svelte` — per-row
+  status, Submit button with disabled-state matrix, refresh on
+  success, surfaces batch errors inline.
+- `ui/frontend/src/lib/sidebar/inspector-tab.svelte` and
+  `ui/frontend/src/lib/active-view/map.svelte` — switched to
+  `renderedReport`.
+- `ui/frontend/src/routes/games/[id]/+layout.svelte` — wires the
+  rendered report and galaxy-client contexts; runs
+  `orderDraft.hydrateFromServer(...)` after the boot
+  `Promise.all` resolves when `needsServerHydration`.
+- `ui/frontend/src/lib/i18n/locales/{en,ru}.ts` — keys for
+  rename action / editor / order statuses / submit copy.
+- Tests: `entity-name.test.ts`, `submit.test.ts`,
+  `order-load.test.ts`, `order-overlay.test.ts`,

 ## Store
 
@@ -124,6 +157,70 @@ The order tab consumes the store via
 `getContext(ORDER_DRAFT_CONTEXT_KEY)`; Phase 14's planet inspector
 will use the same key to push a new command.
 
+## Submit pipeline
+
+`sync/submit.ts` wraps `GalaxyClient.executeCommand("user.games.order", …)`:
+
+1. The order tab filters the draft to `valid` entries, calls
+   `markSubmitting(ids)` so each row reads `submitting`, then
+   posts the snapshot through `submitOrder`.
+2. `submitOrder` builds the FBS `UserGamesOrder` request (game_id,
+   `updatedAt = 0` in Phase 14, every command encoded as a
+   `CommandItem` with the typed payload union) and signs it via
+   the existing `executeCommand` orchestration.
+3. The engine validates, stores, and answers `202 Accepted` with
+   the stored order body — `game_id`, `updatedAt`, plus each
+   command echoed with `cmdApplied` and (on rejection)
+   `cmdErrorCode`.
+4. The gateway re-encodes that JSON into FBS
+   `UserGamesOrderResponse`, and the frontend parses it back into
+   `Map<cmdId, "applied" | "rejected">`.
+5. The order tab calls `applyResults` on the draft, then
+   `gameState.refresh()` to fetch a fresh report. The optimistic
+   overlay (`api/game-state.ts.applyOrderOverlay`) keeps the
+   player's intent visible on the map / inspector even if the
+   engine has not yet applied the rename — turn cutoff resolves
+   the divergence on the next report.
+
+If the gateway answers with a non-`ok` `resultCode` (auth /
+transcoder / engine validation), the submit pipeline marks every
+in-flight entry as `rejected` and surfaces the gateway's error
+message inline; no refresh is issued. Network exceptions revert
+in-flight entries back to `valid` so the operator can retry.
+
+## Optimistic overlay
+
+`applyOrderOverlay(report, commands, statuses)` (in
+`api/game-state.ts`) returns a copy of the server `GameReport`
+with every command in `applied` or `submitting` status projected
+on top. Phase 14 understands `planetRename` only; future phases
+extend the switch.
+
+The overlay has its own context (`RENDERED_REPORT_CONTEXT_KEY`,
+`lib/rendered-report.svelte.ts`) — the in-game shell layout owns
+the source and exposes it to the inspector tab, the mobile sheet,
+and the map renderer. Raw `gameState.report` stays available for
+debugging and for any future consumer that needs the un-overlaid
+snapshot (history mode is the planned reader).
+
+## Server hydration on cache miss
+
+`OrderDraftStore` records `needsServerHydration = true` when no
+cache row exists for the active game (fresh install, cleared
+storage, switching device). After the layout boot resolves both
+`gameState.init` and `orderDraft.init`, it calls
+`orderDraft.hydrateFromServer({ client, turn })` which issues
+`user.games.order.get` against the gateway. A `found = false`
+answer leaves the draft empty; a stored order is decoded into
+`OrderCommand[]` and persisted to the local cache so subsequent
+reloads use the cached copy.
+
+An *explicitly* empty cache row (the user has removed every
+command they composed) does not trigger hydration — local intent
+always wins over the server snapshot. The "did this row exist?"
+distinction matters: `Cache.get` returns `undefined` on a miss
+and `[]` on an explicitly stored empty array.
