# Project State
## Project Reference
See: .planning/PROJECT.md (updated 2026-03-11)
**Core value:** Users can reliably search and find any transaction across all connected Camel instances -- by any combination of state, time, duration, or content -- even at millions of transactions per day with 30-day retention.
**Current focus:** Phase 2: Transaction Search + Diagrams
## Current Position
Phase: 2 of 4 (Transaction Search + Diagrams) -- COMPLETE
Plan: 4 of 4 in current phase (gap closure)
Status: Phase 02 Complete (including gap closure)
Last activity: 2026-03-11 -- Completed 02-04 (Diagram hash linking, Surefire fix, test stability)
Progress: [██████████] 100%

## Accumulated Context
### Decisions
Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:
- [Roadmap]: ClickHouse chosen as primary store (research recommendation, HIGH confidence)
- [Roadmap]: Full-text search starts with ClickHouse skip indexes (tokenbf_v1), OpenSearch deferred
- [Roadmap]: Phases 2 and 3 can execute in parallel (both depend only on Phase 1)
- [Roadmap]: Web UI deferred to v2
- [Phase 01]: Used spring-boot-starter-jdbc for JdbcTemplate + HikariCP auto-config
- [Phase 01]: Created MetricsSnapshot record in core module (cameleer3-common has no metrics model)
- [Phase 01]: Upgraded testcontainers to 2.0.3 for Docker Desktop 29.x compatibility
- [Phase 01]: Changed error_message/error_stacktrace to non-nullable String for tokenbf_v1 index compat
- [Phase 01]: TTL expressions require toDateTime() cast for DateTime64 columns in ClickHouse 25.3
- [Phase 01]: Controllers accept raw String body to support both single and array JSON payloads
- [Phase 01]: IngestionService is a plain class in core module, wired as bean by IngestionBeanConfig in app
- [Phase 01]: Removed @Configuration from IngestionConfig to fix duplicate bean with @EnableConfigurationProperties
- [Phase 02]: FlatProcessor record captures depth and parentIndex during DFS traversal
- [Phase 02]: Exchange bodies/headers concatenated into single String columns for LIKE search
- [Phase 02]: Headers serialized to JSON via Jackson ObjectMapper (static instance)
- [Phase 02]: DiagramRenderer/DiagramLayout stubs created to resolve pre-existing compilation blocker
- [Phase 02]: ELK layered algorithm with top-to-bottom direction for route diagram layout
- [Phase 02]: JFreeSVG over Batik for lightweight server-side SVG generation
- [Phase 02]: Manual Accept header parsing -- JSON only when first preference, SVG as default
- [Phase 02]: xtext xbase lib required at runtime by ELK 0.11.0 LayeredMetaDataProvider
- [Phase 02]: Compound node children detected from RouteNode.getChildren() (matches agent graph model)
- [Phase 02]: Search tests use correlationId scoping for shared ClickHouse isolation
- [Phase 02]: findProcessorSnapshot uses ClickHouse 1-indexed array access
- [Phase 02]: DetailController injects ClickHouseExecutionRepository directly for snapshot (not via interface)
- [Phase 02]: DiagramRepository injected via constructor into ClickHouseExecutionRepository for diagram hash lookup during batch insert
- [Phase 02]: Awaitility ignoreExceptions pattern adopted for all ClickHouse polling assertions
- [Phase 02]: Surefire and Failsafe both need reuseForks=false for ELK classloader isolation
### Pending Todos
None yet.
### Blockers/Concerns
- [Phase 1]: ClickHouse Java client API needs phase-specific research (library has undergone changes)
- [Phase 1]: Must read cameleer3-common PROTOCOL.md before designing ClickHouse schema
- [Phase 2]: Diagram rendering library selection is an open question (Batik, jsvg, JGraphX, or client-side)
- [Phase 2]: ClickHouse skip indexes may not suffice for full-text; decision point during Phase 2
