Handbook
Forge control-plane stack
fl (workspace visibility), fp (platform contracts), ff (job execution), fwc (workcells), lcdl (governed LLM) — complementary layers operators compose; not one monorepo.
The collision
Feature placed in wrong layer — e.g. Docker job orchestration coded in Lenses, or LLM parse logic in Fleet SQLite admin.
How to choose
1) Inspect/guide repos, Studio, local FTS? → fl. 2) ForgeRun, AgentRun, campaign schemas, ADRs? → fp (handbook fpw). 3) Bearer-gated docker_argv jobs, git-self-update? → ff. 4) Pack/workcell execution, local_llm_worker? → fwc. 5) Governed LLM task/operator, OWA atoms? → lcdl. 6) Cross-cutting doc? → Platform handbook + Lenses handbook — link, don't duplicate.
Using several at once
Cockpit ingest orchestrates lcdl+cdp+ff but is not listed as core schema owner — control-plane docs in fp tie the narrative; fl surfaces workspace health.
Terms covered
Examples from chat / plan.md
Docs Health job → ff schedules container; fl may display outcome; lcdl not required unless LLM break-in enabled.
New EvidencePacket field → fp schema first; consumers (fwc, ff jobs) bump against fp handbook contract.
