Ratification draft (Jason, 2026-07-09) extending NORTH_STAR.yaml with NS-10..NS-13 and workstreams J/K/W/P/Q/X. Written against origin/main's fleet suite (F4/F6 anchors, H2 profiles, native backlog per ASM-1). Homelab is the trial environment (D12); USC/web1 adopts post-trial. See proposals/mosaic-platform-prd/README.md for the full decision record D1-D12. Not yet merged into NORTH_STAR.yaml — landing and card decomposition are the homelab orchestrator's mission.

# PRD — HMI Main Agent ("Jarvis") · Workstream J
|
||
|
||
> **Status:** DRAFT for ratification · **Source of truth once landed:** NORTH_STAR.yaml goals J1–J5
|
||
> **Depends on upstream:** H2 (system-type profiles), A3a (card lifecycle), B1 (supervisor tick), F4/K1 (Matrix connector)
|
||
|
||
## Mission
|
||
|
||
Every Mosaic system gets exactly one always-on human-machine-interface agent — default alias **Jarvis**, unit `mosaic-agent@main.service` — that owns the human relationship: conversation, idea development, schedule, email, tasks, knowledge. It delegates all engineering/research/ops work to the orchestrator (**Mos**, `mosaic-agent@orchestrator.service`) through the Mosaic Backlog, and reports fleet status to the user without ever interrupting the orchestrator.
|
||
|
||
This solves the observed failure mode: a busy orchestrator that can't respond, accumulates conversational context rot, and derails over time. Post-split, the orchestrator's context is execution-only.
|
||
|
||
## Requirements
|
||
|
||
### Persona & runtime (J1)
|
||
|
||
| ID | Requirement |
|
||
|---|---|
|
||
| J-R1 | Jarvis is provisioned from the personal-assistant persona baseline via system-type profiles (H2/H3); alias, model tier, host, and channel are profile fields, not code. |
|
||
| J-R2 | Default model tier **Opus** (ratified D11); the orchestrator's tier is independent. |
|
||
| J-R3 | Jarvis survives reboot under systemd (`mosaic-agent@main`), participates in the fleet heartbeat protocol, and is counted in the supervisor's health floor. |
|
||
| J-R4 | Persona customization is update-surviving per H4 (override layer wins on merge). |
|
||
|
||
### PA toolchain (J2)
|
||
|
||
| ID | Requirement |
|
||
|---|---|
|
||
| J-R5 | Jarvis executes personal-assistant mutations **directly** in the user's workspace via the product API: tasks, events/calendar, knowledge entries, ideas, tickets. No delegation for PA ops (ratified D4). |
|
||
| J-R6 | External PA integrations (email, external calendars, helpdesk) are workspace-scoped integrations with credentials in the product credential vault; actions flagged `requires_approval` route through the permission relay (workstream P). |
|
||
| J-R7 | Until tenant-1 migration (X2) completes, Jarvis may read/write the jarvis-brain flat files as a transitional adapter; the adapter is deleted at X2 cutover. |
|
||
|
||
### Delegation contract (J3)
|
||
|
||
| ID | Requirement |
|
||
|---|---|
|
||
| J-R8 | The Jarvis→Mos handoff is **only** via Mosaic Backlog cards: goal, acceptance criteria, priority, depends_on, advisory budget. Never via chat messages to the orchestrator. |
|
||
| J-R9 | Jarvis translates conversation outcomes into card sets; ambiguity is resolved with the user *before* card creation — the orchestrator receives only decision-complete work. |
|
||
| J-R10 | Card authorship is attributed (author=main-agent, ratified-by=user where applicable) for audit. |
|
||
| J-R11 | Authority line: Mos holds all execution and merge authority (NS-4). Jarvis relays the user's GO/NO-GO gates as card state, and never acquires fleet mutation, merge, or dispatch rights. |
|
||
|
||
### Passive observability (J4)
|
||
|
||
| ID | Requirement |
|
||
|---|---|
|
||
| J-R12 | Jarvis answers "what's the fleet doing" from read-only sources: heartbeat files, `mosaic fleet ps` JSON, backlog card states, CI status. Zero messages to the orchestrator for status. |
|
||
| J-R13 | Jarvis proactively surfaces to the user: blocked cards, failed CI on user-ratified missions, approval requests pending, budget advisories. (PDA-friendly phrasing per SOUL.md.) |
|
||
|
||
### Channel (J5)
|
||
|
||
| ID | Requirement |
|
||
|---|---|
|
||
| J-R14 | Jarvis's conversation lives in a dedicated Matrix room on the self-hosted homeserver via `OrchestratorConnector(matrix)` (K1). Matrix-first: no Discord channel is created for Jarvis (ratified D1). |
|
||
| J-R15 | Multi-platform user reach arrives via mautrix bridges (K2); Jarvis's code path is Matrix-only. |
|
||
|
||
## Acceptance criteria
|
||
|
||
1. AC-NS-8: user converses with Jarvis under full orchestrator load; latency unaffected; orchestrator receives zero conversational traffic.
|
||
2. AC-NS-9: a conversationally-agreed mission round-trips (cards → drained → completed → reported by Jarvis) with no chat handoff.
|
||
3. Kill the orchestrator mid-conversation: Jarvis conversation is unaffected; Jarvis reports the outage from heartbeat state.
|
||
4. `!sys`-equivalent admin verbs work in the Matrix room (status/logs/clear/restart of the main agent).
|
||
|
||
## Non-goals
|
||
|
||
- Jarvis executing code/infra changes (that is Mos + fleet).
|
||
- Horizontal sharding of the main agent (rejected in the Matrix charter: split-brain).
|
||
- Per-workspace fleets (post-MVP per ASM-6).
|
||
|
||
## Open items (for Mos's planner)
|
||
|
||
- Context hygiene: Jarvis's durable memory is the workspace (tasks/knowledge/ideas); define its resume protocol (KICKSTART-equivalent) so `/clear` is cheap. ASSUMPTION: mirror the MOS-KICKSTART two-file pattern until the product grows a native session-resume feature.
|
||
- Reconcile the old `apps/api` matrix-bot-sdk workspace bridge with the F4 connector design (one Matrix stack, not two).
