v0.12.0 — Grok Build, Needs You, transcript streaming, iOS UX

Grok Build — first-class backend

• Full xAI OAuth flow (device-auth), ~/.grok/auth.json mirrored per mission workspace, container-aware --cwd translation, grok-build default model exposed via /api/providers.
• /goal <objective> for Grok. Grok ships no native goal mode, so sandboxed.sh drives the loop: a sentinel protocol (<goal_complete/> / <goal_continue/> / <goal_aborted reason="…"/>) is injected into the first-turn prompt, then an AgentFinished automation re-fires a short continuation prompt every turn until the model declares done, the iteration budget (25) is hit, or two consecutive sentinel-missing turns trigger an auto-abort. Iteration / status events use the same SSE shape as codex so the dashboard's iter-N pill and the Automations panel light up without UI changes. Cancellation cleanly tears the loop down (aborted:cancelled).
• Pre-existing Grok bugs fixed. Grok no longer inherits the global DEFAULT_MODEL (was anthropic/claude-opus-4-6, which the CLI rejected). Continuations use -s/--session-id (upsert semantics) instead of --resume so orphan sessions from a failed first turn self-heal.

"Needs You" mission lifecycle

• New MissionStatus::AwaitingUser / Acknowledged variants. Turn-complete-with-no-follow-up parks the mission in AwaitingUser instead of Completed. Opening the mission stamps first_viewed_at; a 1 h grace timer promotes the mission to Acknowledged. Any new user message wakes it back to Active.
• Dashboard column rewired: Needs You = awaiting_user; Finished = completed / acknowledged / failed / interrupted / blocked / not_feasible with green/red tone via finishedTone(status). New POST /api/control/missions/:id/opened broadcasts the state change so other open clients re-tint without a refresh.
• New GET /api/control/missions/:id/{transcript,trace} endpoints split the mission view: chat paints from transcript (small, fast) and tool/thinking activity hydrates from trace after first paint. Storage backends (sqlite/memory/file) updated with first_viewed_at + idempotent migration.

iOS UX responsiveness pass

• Mission switch is cache-first — opening a recent mission renders instantly instead of behind a spinner.
• Parallelized RTTs — loadMission / switchToMission fan out metadata + events via async let; BackendAgentService walks per-backend configs and agents via two withTaskGroups instead of N sequential awaits.
• Synchronous-optimistic gestures everywhere: queue swipe-to-delete + clear, mission delete, automation toggle / delete, mission status menu, mission cancel chip, send-message bubble (isPending), FIDO approve/deny — all mutate local state on the same frame as the gesture, then fire the network call.
• Files browser: per-path LRU cache with stale-while-revalidate so navigation doesn't blank.
• Skeleton scaffolds on History, Files, Workspaces initial loads (replaces full-screen LoadingView).
• Cosmetic latency deleted: SetupSheet 500 ms post-success sleep, Terminal 500 ms "fake connect" timer, 300 ms workspace-switch reconnect delay. Terminal now promotes to .connected on first message with a 3 s safety fallback for silent shells.

Transcript performance & correctness

• Mission history streams newest-first; cache hydrates instantly on reopen.
• "Load older messages" pinning bug fixed on web + iOS: metaTotal is now computed from the loadable subset of event_counts only.
• Deferred trace merge deduplicates by sequence (web Map, iOS [Int64: StoredEvent]).

Cleanup & fixes

• Amp/ampcode backend removed.
• Local dashboard API-base inference; config naming aligned.
• xAI add-provider modal now selects ["opencode", "grok"] for both OAuth-method and direct-provider paths.
• Thinking panel default reverted to closed (auto-show on thinking-start remains).
• Trace API limit/offset use !== undefined so offset: 0 survives.
• Favicon dot colors aligned with STATUS_DOT_COLORS palette.
• Clippy clean against Rust 1.95.
