The Studium engine + chamber-library are David's **personal** projects — but Seb now recognizes them as **fundamental to the shared CapableMind vision**. The strategic value of keeping them separate: David can **experiment unfettered** on the library/engine without risk of breaking CM's production L1/BMF runtime — while breakthroughs still **transfer CM-ward**. The engine is a *microcosm of CM*: the same governance thesis (executor/jurist/steward loop, L2-over-L1, honest-degradation / earned-confidence) instantiated over a bounded, provenanced library instead of the L1 runtime. Code-separable (zero L1/BMF/`mcp__capablemind` imports; verified 2026-07-08); coupled only at the governance-thesis level.
Concrete transfer surface — the V2 verifier work is the live example: per-language honest-degradation semantics ↔ CM's honest-degradation contract (REVIEWED-22); abstain-when-ungrounded ↔ earned-confidence ("the system does not grant epistemic authority to its own outputs without external grounding", REVIEWED-19); per-language trust/revise/abstain thresholds against a real failure taxonomy ↔ the confidence-floor/ceiling invariants (I-CF / I-CC), which L1 has only specified abstractly. Studium is where CM's epistemic-integrity invariants get pressure-tested on a real corpus before L1 hardens them.
**Why:** this is the rationale for concentrating effort on the library/engine — a safe, unfettered ground for the epistemic risks CM's live runtime cannot take, with a transfer path back. Named by the steward 2026-07-08 (the Fable-window allocation conversation).
**How to apply:** treat Studium/chamber as the experimentation sandbox (design freely, take research-grade risks there); when designing there, actively surface what transfers to CM — cf. the V2 charter's Deliverable 9, the CM-transfer note (`studium-engine/docs/v2-validation-harness-scope-charter-2026-07-08.md`). Keep them distinct projects — don't conflate Studium with CM, kin to [[mempalace-is-unaffiliated-stopgap]]'s build-vs-use discipline — but do harvest the transfer. Companion to [[project-studium-engine-telos-chamber-of-voices]] and [[reference-studium-engine-architectural-charter]].
