# Tasks — MVP (Top-Level Rollup)

> Single-writer: orchestrator only. Workers read but never modify.
>
> **Mission:** mvp-20260312
> **Manifest:** [docs/MISSION-MANIFEST.md](./MISSION-MANIFEST.md)
>
> This file is a **rollup**. Per-workstream task breakdowns live in workstream task files
> (e.g. `docs/federation/TASKS.md`). Workers operating inside a workstream should treat
> the workstream file as their primary task source; this file exists for orchestrator-level
> visibility into MVP-wide state.
>
> **Status values:** `not-started` | `in-progress` | `done` | `blocked` | `failed`

## Workstream Rollup

| id  | status            | workstream          | progress         | tasks file                                        | notes                                                           |
| --- | ----------------- | ------------------- | ---------------- | ------------------------------------------------- | --------------------------------------------------------------- |
| W1  | planning-complete | Federation v1 (FED) | 0 / 7 milestones | [docs/federation/TASKS.md](./federation/TASKS.md) | M1 task breakdown populated; M2–M7 deferred to mission planning |

## Cross-Cutting Tracking

These are MVP-level checks that don't belong to any single workstream. Updated by the orchestrator at each session.

## Pointer to Active Workstream

Active workstream is **W1 — Federation v1**. Workers should:

1. Read [docs/federation/MISSION-MANIFEST.md](./federation/MISSION-MANIFEST.md) for workstream scope
2. Read [docs/federation/TASKS.md](./federation/TASKS.md) for the next pending task
3. Follow per-task agent + tier guidance from the workstream manifest

## Thin-core prompt diet (#528) — feat/contract-thin-core

- Status: PR open, awaiting maintainer merge ratification (fleet-governing change).
- Cut always-injected contract AGENTS+TOOLS+RUNTIME 8,827→4,122 tok (−53%); all 12 hard gates intact.
- Validation: deterministic gate-checklist PASS; headless A/B thin 7/9 vs monolith 5/9. Detail: scratchpads/contract-thin-core.md.

## P5 — Overlay composer + cross-harness (#604) — feat/p5-overlay-composer

- Status: in progress. R7 (compose-contract) + R8 (cross-harness) + R9 (composer test).
- `composeContract({harness, mosaicHome})` pure fn + `.local` overlay deltas-by-value; `mosaic compose-contract <harness>` command; AGENTS bare-launch nudge; composer spec (per-tier anchor + Tier-3 byte-equality). Detail: scratchpads/p5-overlay-composer.md.
- Defer to P6: CONTRIBUTING.md + compliance matrix; line-count CI ceiling; aiguide; alpha tag.
