# Mosaic Fleet — NORTH_STAR (machine-readable source of truth)
#
# This file is the single machine-readable source of truth for fleet planning.
# Prose docs (including NORTH_STAR.md) are deterministic PROJECTIONS of this file.
# Regenerate the Markdown projection with the pure generator in
# packages/mosaic/src/commands/fleet.ts (renderNorthStarMarkdown). Edit the YAML,
# never the .md.
#
# Self-contained Mosaic. NO Hermes runtime dependency. The backlog of record is
# the Mosaic Backlog on Mosaic's OWN native Postgres storage service.

version: 1

mission: >-
  A self-driving Mosaic delivery fleet that 24/7 unattended converts a
  machine-readable goal set into merged, CI-green, budget-bounded change —
  looping plan→backlog→assign→execute→verify→merge→reassess — on Mosaic's OWN
  native backlog/dispatch engine.

substrate:
  note: >-
    The Mosaic Backlog is the backlog of record + dispatch engine, built on
    Mosaic's native Postgres storage service (@mosaicstack/db drizzle;
    PGlite-embedded by default, full Postgres by config). NOT Hermes.

standing_objectives:
  - id: NS-1
    text: >-
      Single machine-readable source (this file) drives planning; prose docs are
      projections.
  - id: NS-2
    text: >-
      Every backlog item is an independently-shippable unit with stable id,
      priority, depends_on DAG, represented as a Mosaic Backlog card; spend
      tracked as advisory projection.
  - id: NS-3
    text: >-
      The supervisor guarantees movement: no idle agent while ready
      dependency-satisfied work exists; no empty backlog without a replan
      request; assignment via Mosaic native dispatch/claim.
  - id: NS-4
    text: >-
      Exactly one merge-gate approver; nothing reaches main except via
      pr-merge.sh after pr-ci-wait.sh success; Gitea branch protection is the
      backstop.
  - id: NS-5
    text: >-
      Every unit bounded by wall-clock TTL on its claim; token caps enforced
      only where a real meter exists, else advisory.
  - id: NS-6
    text: >-
      Context cleared between tasks for ephemeral runners
      (reset_between_tasks); persona+mission re-injected per task.
  - id: NS-7
    text: >-
      Meta-loop (session-review + enhancer) continuously proposes small
      fleet-improvement PRs.
  - id: NS-8
    text: >-
      Single operator-flippable PAUSE kill-switch (fleet/run/PAUSED) honored
      before every dispatch and every merge.

success_criteria:
  - id: AC-NS-1
    text: >-
      The supervisor keeps a two-agent floor (1 orchestrator + >=1 enhancer)
      healthy across reboot.
  - id: AC-NS-2
    text: >-
      A goal added to this YAML is decomposed to cards and either merged or
      escalated, with no human in the loop.
  - id: AC-NS-3
    text: >-
      No PR merges with failure/error/no-status/timeout CI, and none bypass
      pr-merge.sh.
  - id: AC-NS-4
    text: >-
      TTL is enforced on claims; token caps remain advisory until a real meter
      exists.
  - id: AC-NS-5
    text: >-
      Flipping fleet/run/PAUSED halts dispatch and merges within one tick.

assumptions:
  - id: ASM-1
    vetoable: true
    text: >-
      The Mosaic Backlog on the native Postgres storage service is the backlog
      of record.
  - id: ASM-2
    vetoable: true
    text: >-
      Claude gate roles have no native busy status, so readiness = pane-idle +
      heartbeat.
  - id: ASM-3
    vetoable: true
    text: 'Two-agent floor = 1 orchestrator + >=1 enhancer.'

spend:
  advisory: true
  note: >-
    No per-task token meter yet; budgets degrade to TTL. Spend is tracked only
    as an advisory projection alongside each card.
