docs(fleet): DRAFT PRD proposal — Jarvis HMI main agent, Matrix-first transport, webUI fleet control, permission relay, backlog providers, Hermes decommission
Some checks failed
ci/woodpecker/push/ci Pipeline failed

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.

# Proposed additions to docs/fleet/NORTH_STAR.yaml — DRAFT (Jason ratification pending, 2026-07-09)
#
# Merge these entries into the existing NORTH_STAR.yaml sections, then regenerate
# NORTH_STAR.md via renderNorthStarMarkdown (packages/mosaic/src/commands/fleet.ts).
# Ids chosen to avoid collision with existing workstreams AH and goals.
standing_objectives:
- id: NS-10
text: >-
Every Mosaic system runs exactly one always-on HMI main agent (default
alias "Jarvis", unit mosaic-agent@main) that owns all human conversation
and user-level personal-assistant work (ideas, schedule, email, tasks,
knowledge) and delegates engineering/research/ops missions to the
orchestrator as Mosaic Backlog cards; the main agent never executes fleet
work itself and never interrupts the orchestrator for status.
- id: NS-11
text: >-
Irreversible or externally-visible agent actions pass a human-in-the-loop
permission relay (approve/deny from chat or webUI) governed by
per-capability guard rails; prepare freely, execute with approval.
- id: NS-12
text: >-
The Mosaic Backlog remains the sole backlog of record; external providers
(Gitea, GitHub, local kanban, …) attach as bidirectional sync adapters,
never as the record.
- id: NS-13
text: >-
Hermes is fully decommissioned once Mosaic reaches verified parity on
transport (Matrix connector), task board (native backlog + webUI),
permission relay, and multi-platform reach (mautrix bridges).
success_criteria:
- id: AC-NS-8
text: >-
A user converses with the main agent in its Matrix room while the
orchestrator is under full load; main-agent response latency is unaffected
and the orchestrator receives zero conversational traffic.
- id: AC-NS-9
text: >-
A mission agreed in the main-agent conversation appears as a backlog card
set with acceptance criteria, is drained by the orchestrator without
chat-level handoff, and its completion is reported back to the user by the
main agent from board/heartbeat state alone.
- id: AC-NS-10
text: >-
An action listed as requires_approval executes only after an explicit
human approve from Matrix or webUI; deny and timeout paths leave the
system unchanged and audited.
- id: AC-NS-11
text: >-
With Hermes stopped, no fleet or main-agent capability regresses
(transport, board, approvals, multi-platform reach all served by Mosaic).

assumptions:
- id: ASM-5
vetoable: true
text: >-
The main agent initially runs on the homelab fleet host alongside the
orchestrator under mosaic-agent@main.service; host placement is a config
field, not a code assumption.
- id: ASM-6
vetoable: true
text: >-
Product multi-tenancy at MVP means self-hosted installs with multiple
workspaces per install (Authentik OIDC); per-tenant isolated FLEETS
(agents per workspace) are post-MVP.
- id: ASM-7
vetoable: true
text: >-
mautrix bridges are deployed as infrastructure (GitOps), not as Mosaic
application code; Mosaic's only conversational protocol is Matrix.
- id: ASM-8
vetoable: true
text: >-
During migration (before X3), Hermes remains running untouched; no
Hermes-dependent capability is removed until its Mosaic replacement is
verified in production.
- id: ASM-9
vetoable: true
text: >-
The trial environment is the homelab fleet deployment (D12). Environments
running the primitive-era implementation (USC/web1: mos-claude.service,
Hermes, jarvis-brain boards) are untouched during the trial; workstream X
executes there as a post-trial adoption phase, environment by
environment.
