Handbook
L4 — Feature/component
Status: Vision — policy defined; no PoC or Platform-native enforcement today.
Level at a glance
| Autonomous unit | Capability across modules; may add a component within existing architecture; cross-repo, one platform |
| What stays fixed | Platform, major architecture |
| Human gate | ADR + release gate |
Canonical policy: Autonomy levels (Blueprints).
Building blocks at this level (planned)
| Building block | Planned role at L4 | Handbook link |
|---|---|---|
| forge-lenses | ForgeRun system of record; evidence review before release | Workflows and runs |
| Forge Campaign | Multi-repo effort under one frun_*; manifest phases |
Forge Campaign |
| forge-lcdl | Governed reasoning graphs for complex planning | Platform reference architecture §5 |
| forge-fleet | Optional container execution for audit/remediate workers | Platform reference architecture §6 |
| forge-workcells | campaign_orchestrator, fleet_ux_worker, cursor_cli |
Workcell catalog |
| blueprints | ADR ceremony; Assay Gate at release boundary | Assay Gate |
| forge-platform | Schemas, ADRs, ecosystem contracts | Platform reference architecture |
All L0–L3 blocks remain available for sub-tasks within an L4 campaign; L4 adds cross-module scope and ADR/release gates.

Gates and evidence (vision)
Inherits all L0–L3 gates for constituent work, plus:
- ADR recorded for architectural decisions introduced at this level
- Release gate (Assay Gate ceremony) before promotion
- Cross-module acceptance criteria in campaign manifest
No automated L4-specific assay exists in Dark Factory or Platform workcells today.
Implemented vs planned
| Implemented | Policy table row; Forge Campaign manifest sketch; workcell catalog ids |
| Not implemented | L4 assay enforcement; demonstrated multi-module autonomous delivery |
| Planned | Campaign orchestrator with L4 manifest constraints; ADR linkage in EvidencePacket |
