rpe-context-assembler

Section: section5-rpe Subsystem: telegram-services_v2 Port: — Deploy type: image-copy Compose: telegram-services_v2/phase2-section5-rpe/docker-compose.yml

Fragile: IMAGE-COPY — requires build + up -d. Loads KnownPersons scoped to the CURRENT SPEAKER's UserProfile — not the channel owner. Historical bug: was fetching channel owner's KnownPersons instead (Laura identity bug 2026-04-18).

Description

RPE context assembly service

Role

Assembles relational context (KnownPersons, UserProfile, channel history) for each incoming message

Dependencies

hard rabbitmq (prysm-store)

hard agent-tools (section4.5-agent)

hard rpe-classifier (section5-rpe)

hard rpe-dynamics (section5-rpe)

hard rpe-extractor (section5-rpe)

Runbooks

Diagnose missing botScopeUuid in rpe-context-assembler (Layer 2 skipped) data-quality

Diagnose missing prompt_modifier key for relationship context block data-quality

Diagnose missing userScopeUuid in rpe-context-assembler (degraded render) data-quality

Behavioral Assertions

rpe.assemble queue has exactly 1 consumer
Input: Normal operating state
Expected: RabbitMQ management API: queue rpe.assemble consumer_count = 1

Analysis fanout completes within 30 seconds (all 5 analysis services respond)
Input: DM message processed through full RPE pipeline
Expected: Time between request.dispatched (fanout) and request.dispatched (to agent-brain) < 30s

Diagnostic Tools

Check Redis relationship block cache for a channel bash —

Check relationship_members for NULL scope_uuids sql —

Verify bots table has scope_uuid for all rows sql —

Verify context_modifier keys exist in prompt_modifiers for all active channels sql —
