# 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 1: Ingestion Pipeline + API Foundation

## Current Position

Phase: 1 of 4 (Ingestion Pipeline + API Foundation) -- COMPLETE
Plan: 3 of 3 in current phase
Status: Phase 1 Complete
Last activity: 2026-03-11 -- Completed 01-02 (Ingestion endpoints, ClickHouse repositories, flush scheduler, 11 ITs)

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

### 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
