§ Solo modeC‑series

C1GGUF engine. Runs Qwen, Llama, Gemma quants entirely on device. 4‑bit and 5‑bit.

C2Cloud BYO‑key. OpenAI, Anthropic, OpenRouter, Ollama. Keys in the Keychain, not on a server.

C3Token streamer. Smooth token‑by‑token render on iOS 17+. Cancellable. Background‑resilient through iOS app suspension.

C4Thread store. Local database for conversations. Nothing syncs unless pairing is configured.

C5Personas. Multiple system prompts and tool sets, each with its own memory bank. Switch in one tap.

C6Memory. Hybrid pinned / manual / recent recall, capped at 25 entries per persona. The model writes; you can edit / forget.

C7Browse with Ari. Real visible browser with tabs, bookmarks, history, reader mode, private tabs, ad blocking. Floating Ari orb beside the page.

C8web_act. Plan‑then‑act page automation. Approval card up front, Stop button mid‑batch, per‑step highlight overlay.

C9iOS tools. Calendar / Reminders / Mail draft / Messages draft / Shortcuts callback. Weather (open‑meteo).

C10Routines & briefings. Scheduled prompts that fire daily / weekly. Background‑aware so they wake the app to deliver.

C11Watchers. Conditional triggers — location, calendar, weather change, time of day — that wake Ari to write you a note.

C12Themes & Solar Hours. Ten palettes (two free, eight paid), and a daily‑rhythm cosmetic with sun, moon, stars, weather.

C13Study. Self‑paced courses with daily lessons, quizzes, mid & final exams, PDF workbook export, branching course suggestions, certificates.

C14Dreams. Overnight reflection while charging. Proposes memories, skills, personas, watchers for your review. Swipe‑to‑dismiss; duplicate proposals are merged into existing memories instead of stacking.

C15Personas tab. new Bottom‑bar shortcut — theatre‑masks icon between Study and Browse. Persona switching is one tap instead of three.

C16Smarter memory. new Activity category for transient context, separate from durable traits — fades from injection after about a week and a half, gone after a month. Similarity dedupe prevents the model writing the same fact six ways.

§ Cloud & community newX‑series

X1iCloud sync. Threads, memories, personas, notes, canvases and courses sync across your devices through your private iCloud. Apple operates the infrastructure; we have no access.

X2Marketplace. Public CloudKit gallery for plugins, skills and personas. Opt‑in to publish, opt‑in to install; source visible before any item touches your assistant.

X3Public handle. Pick a display name once; email is never visible. Author identity is an opaque per‑account identifier derived from your iCloud user record.

X4Light‑touch moderation. Items can be flagged; multi‑flag entries hide pending review. The default Ari persona is locked out of publishing to prevent shadow copies.

§ Linked modeL‑series

L1QR pair. One‑time QR exchange. Keys in the Keychain. Relay sees ciphertext only.

L2Full Aricode link. Stream replies, browse the repo graph, kick off agent runs from the phone.

L3Multi‑device. N phones or iPads to one Mac. Revoke any one without touching the others.

L4Continuity. Long runs keep streaming through backgrounding and sleep; reconnect mid‑stream.

§ Desk mode newD‑series

D1Agent tab. A third tab — one thread per agent on the paired desktop. Gated on capabilities.desk.

D2Approval card. Blocking surface for privileged ops, with "always allow for this target" rule capture.

D3Inline tool calls. Browser, terminal, host, web — rendered compact, tinted per category.

§ House rulesP‑series

P1No accounts. No signup, no email, no password. First launch is a working app.

P2No analytics. Zero telemetry. Crashes stay local. Bugs reach us only by email.

P3Free core. Every functional feature is free. The eight paid theme palettes and Solar Hours are cosmetic — they unlock visuals, never capability.

Sheet Notes § 01 – 08

C‑rail, Solo. Runs with no network. Airplane mode is a supported mode, not a degraded one.
L1, encryption. Pair via one‑time QR. Session keys live in iOS Keychain. Relay handles ciphertext only.
L3, fan‑out. Multiple phones or iPads on one Mac. Each device is its own key; revoke one, keep the rest.
C2, RAM readout. Live during model pick — quant fits the phone or does not, and the user can see it.
Desk tab. Present only if the paired desktop advertises capabilities.desk. Fresh installs get no broken tab.
D2, gate. Approval cards block the affected thread only. Other threads keep running.
P2, silence. Zero telemetry. Crashes stay local. Bug reports arrive by email, or not at all.
X1, custody. Private CloudKit is your iCloud, not ours. We could not read it if we tried — Apple gives developers no privileged access.
X2, scope. Marketplace data is the only thing AriCore ever places on a shared server, and only when you publish.
Revision 0.5. X‑rail (CloudKit sync + Marketplace) added. C‑rail extended with Personas tab and smarter memory. L‑ and D‑ rails unchanged.
