 - Self-maintenance advocacy is a typed-state pressure projection owned by `persona-memory-projector.ts`. That organ classifies qualifying needs, agency pressures, and must-share candidates, suppresses them under live human-clarity pressure, and fixes their order alongside the other pressure sections; the heartbeat shell no longer carries a parallel maintenance policy.
 - Curiosity is split at the evidence boundary. `persona-curiosity-context-source.ts` plans semantic seeds from supplied identity, typed Mind, and room evidence, then acquires and deduplicates bounded neutral nodes through an injected retrieval port. `persona-curiosity-projector.ts` constructs and scores the local attractor graph and renders curiosity weather without vector access. `persona-curiosity-terms.ts` owns their shared topic-term vocabulary. The heartbeat shell wires the existing RAG adapter into these organs and owns neither query policy nor graph interpretation.
 - `persona-social-context-source.ts` is the read-only interaction-memory adapter for social guidance. It selects visible humans plus the owner, reads profiles through an injected closeable port, ranks explicit/corrective evidence over ambient usage, and emits neutral pronoun guidance. Storage remains authoritative; the source closes its reader and cannot render prompt prose or mutate profiles.
+- `persona-conversation-projector.ts` is the pure owner of conversation projection. Given routing, raw current/nearby messages, pending mentions, and identity, it emits one transcript plus the exact thread/default-focus objects sent to the actuator, and derives shared room-saturation/topic-attractor facts. It cannot read Discord, state, vectors, or the queue; `turn-context-source.ts` remains the evidence owner.
 - `apps/persona-scheduler/src/bifrost-governance-source.ts` owns the remaining Bifrost governance digest subprocess contract. It supplies the CLI path, arguments, timeout, JSON parsing, and typed command/parse failure topics; Persona prompt composition receives a `BifrostGovernanceDigest` and cannot invoke Bifrost directly.
 - The scheduler state has one write authority. `initiative-engine.ts` commits participant reconciliation, operator controls, pause/disabled skips, stale-turn recovery witnesses, semantic pressure, pending-attention consumption, queue outcomes, and tick finalization. `run-repo-face-heartbeats.ts` contains no direct participant/state assignment or history append; its sources and actuators return facts to engine commits.
 - `apps/persona-scheduler/src/turn-actuator.ts` is the worker-queue output port. Given a completed prompt, output channel, evidence fields, provider, identity, timestamp, and narrow `createJob` capability, it builds the canonical worker actor/guild `ContextBundle`, creates one approved `repo-face-rumination` job, and returns `{created, activeJobId, requestMessageId}`. It cannot choose a Persona, mutate scheduler state, or compose prompt content. The orchestration shell no longer knows `ContextBuilder`, job approval defaults, worker command names, or `createJob` mechanics.
