No implementation or runtime cutover has started. +> **Working branch:** `feat/fund-grade-data-layer-v2`, created from `dev`. +> **Detailed architecture:** [Fund-grade architecture and migration guide](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md) +> **Compatibility boundary:** Existing `/v1`, SDK v1, Redis keys and Redis Pub/Sub remain supported until a governed per-consumer sunset. + +## 1. How To Use This Tracker + +This file is the tracked implementation journal for the fund-grade data-layer upgrade. The architecture guide owns detailed design and rationale; this file owns execution order, status, evidence, decisions and remaining debt. + +Every phase must keep the following fields current: + +- **Goal:** the measurable outcome, not merely files to create. +- **Guide index:** links to the detailed architecture sections that govern implementation. +- **To do:** approved scope for the phase. +- **Completed:** exact code, configuration, migration and operational work actually performed. +- **Verification:** commands, fixtures, data comparisons, latency/capacity results and cleanup evidence that actually ran. +- **Technical debt / decision gate:** only unresolved matters that require a user, infrastructure, cost or business-semantics decision. In-scope defects are fixed before phase closure, not relabeled as debt. +- **Rollback:** a tested path back to the last authoritative producer/read path. + +Phase status is one of `PLANNED`, `IN_PROGRESS`, `BLOCKED`, `COMPLETE`. A phase is not `COMPLETE` while a required gate is untested or while test artifacts affect live data. + +## 2. Program-Wide Rules And Invariants + +These rules apply to all seven phases. + +1. **No big-bang cutover.** Use strangler migration, shadow reads/writes, parity reports and per-feed authority flags as defined in [Sections 30-33](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md#30-migration-strategy-no-big-bang-rewrite). +2. **V1 remains stable.** Existing alpha and Trading System consumers must not change merely because internal transport, schemas or implementation language changes. Protect `/v1`, SDK v1 and legacy Redis payloads with golden tests. +3. **One canonical contract across languages.** Python and Rust generate types from the same Protobuf/OpenAPI sources. External projects are behavioral references, not naming authorities for established data-layer fields. +4. **Correctness before throughput.** Validate exact decimal representation, venue/market/instrument identity, source/event/receive timestamps, sequence semantics, bar closure, provenance and quality flags before accepting performance results. +5. **No silent loss.** Trade and order-book delta queues must never use “drop oldest and continue healthy”. Backpressure, spool, reconnect, resnapshot and feed-state transitions must be explicit and observable. +6. **Demand controls cost, capability controls architecture.** Unused Spot feeds are disabled by configuration and zero-demand evidence, not deleted. A new consumer can re-enable them through a reviewed `DataRequirement` without code changes. +7. **Multi-venue by capability.** Core code must not route with growing `if venue == ...` branches. Market types include spot, equity, perpetual, dated futures, option and index/reference products. Future Deribit support must fit the existing instrument/event/order-book contracts. +8. **Rust is promoted by evidence.** Rust owns approved hot paths only after shadow parity, replay determinism, failure recovery and capacity gates pass. Python remains the control/query/history authority where it is the better fit. +9. **Tests are isolated and cleaned.** Use deterministic venue fixtures and disposable Compose project names, topics, Redis prefixes, PostgreSQL schemas and object-store buckets. Do not flush shared Redis, alter production parquet, or reuse live consumer groups. Remove test resources and report cleanup after each phase. +10. **Real-provider tests are bounded.** Read-only venue smoke tests use small symbol/feed sets, respect rate limits and never seed/bypass missing data. They supplement deterministic tests; they do not replace them. +11. **Evidence is concise and durable.** Store checksums, counts, latency percentiles, gap/duplicate results and compact report files. Do not paste unbounded logs into this plan. +12. **Commit discipline.** Commit one coherent, tested implementation slice at a time with the configured BobbyAxerol identity. Do not bundle unrelated `symbols.json`, local data, logs or caches. Open PRs into `dev`; promote to `main` only through release gates. +13. **New debt is governed.** Fix in-scope bugs during the phase. Stop and request direction only for a material architecture, infrastructure-cost, licensing, source-authority or public-contract decision. + +## 3.

Phase 0 - Containment, Inventory And Measurable Baseline + +**Status:** `PLANNED` + +### Goal + +Create a trustworthy, reproducible baseline before changing transport or schemas; freeze V1 behavior; identify every real consumer; and stop broad Spot streaming only when no active/declared consumer requires it. + +### Guide Index + +- [Phase 0 detailed guide index: Sections 2, 4, 24, 27, 30-31 and Epic E0](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md#implementation-phase-0) + +### To Do + +- Inventory all REST routes, request/response examples, SDK public methods, Redis keys/channels, source/market semantics and known consumers in alpha, Trading System and diagnostics. +- Snapshot V1 OpenAPI and legacy Redis payloads as golden compatibility artifacts. Record owner, criticality, freshness, warmup and fallback requirements per consumer. +- Measure current host/runtime baseline: enabled feeds, shard count, messages/s, queue depth/drop delta, reconnects, Redis commands/memory/network, API latency, CPU/RSS, parquet coverage and provider REST pressure. +- Add a deterministic baseline corpus for Binance USD-M, Binance Spot, OKX and VN payloads, including malformed, duplicate, out-of-order, reconnect and market-closed cases. +- Separate `liveness`, service `readiness`, feed readiness and execution eligibility in reports without changing V1 response shape. +- Add explicit source/market feature flags and validate configuration at startup. Remove duplicate/hardcoded universe overrides from runtime ownership. +- Prove Spot demand from declaration plus telemetry. If demand is zero, set Spot ingestion disabled by default while preserving Spot REST wrappers, adapter code and a tested re-enable path. +- Establish test-resource namespaces and cleanup commands for broker topics, Redis, PostgreSQL and object storage before those dependencies are introduced. +- Record baseline budgets and acceptance thresholds used by later phases. Thresholds must reflect measured load plus agreed headroom, not arbitrary aspirational numbers. + +### Verification And Exit Gate + +- Golden `/v1`, SDK and Redis compatibility tests pass against the current implementation. +- Consumer inventory covers every observed and declared caller; unknown callers are listed and block destructive contract changes. +- Two bounded runtime windows show demand telemetry, feed freshness, queue/drop deltas, reconnect behavior and resource usage. +- Spot-off configuration starts without Spot WebSocket shards, leaves USD-M/VN demanded feeds healthy, reduces resource use measurably and can be rolled back with one configuration change. +- Existing unit suite, Docker integration suite and read-only sampled provider smoke pass; generated test state is cleaned. +- Baseline report and machine-readable artifacts are committed without credentials or raw unbounded logs. + +### Completed + +- Not started. + +### Technical Debt / Decision Gate + +- Confirm measured production headroom target after baseline results. No infrastructure purchase is assumed in this phase. +- Any consumer that depends on undeclared Spot Pub/Sub must be registered before Spot can remain disabled. + +### Rollback + +- Restore the previous feed-enable configuration and immutable image. No schema, topic or consumer cutover occurs in Phase 0. + +## 5. Phase 1 - Canonical Contracts, Identity And Runtime Boundaries + +**Status:** `PLANNED` + +### Goal + +Define one precise, venue-neutral data domain and split the combined process into independently scalable roles while preserving all V1 behavior. + +### Guide Index + +- [Phase 1 detailed guide index: Sections 8-10, 12, 20-23, P1 and Epics E1-E3](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md#implementation-phase-1) + +### To Do + +- Create versioned Protobuf packages and Buf configuration for common envelope, instrument, trade, BBO/quote, bar, order-book snapshot/delta, quality and feed-state events. +- Preserve price/quantity as exact decimal coefficient/scale or venue-native string; prohibit canonical binary float. +- Implement canonical `instrument_uid`, aliases, venue, source/provider, market/product type, contract expiry, strike, option type, multiplier, tick/lot metadata and trading calendar/session model. +- Define capability descriptors for REST history, trades, BBO, bars, L2 snapshots/deltas, sequence/checksum, resubscribe/resnapshot and source authority. Ensure options and dated contracts need no core schema redesign. +- Build PostgreSQL migrations for instrument master, aliases, source policy, subscription registry, config revisions, leases/fencing and job state. Do not store the tick stream in PostgreSQL. +- Extract deployable Python roles (`api`, `control`, `history`, compatibility facade) from the current combined lifespan. A role flag must have one owner and fail startup on contradictory ownership. +- Keep legacy imports and application entrypoints through explicit facades. API replicas must not create venue subscriptions. +- Write ADRs for contract representation, instrument identity, role boundaries, transport decision inputs and V1 compatibility ownership. + +### Verification And Exit Gate + +- Buf lint/generation and breaking checks pass; generated Python and Rust types encode/decode the same golden bytes. +- Exact decimal, timestamp, event-ID and identity collision suites pass for spot, perpetual, dated futures, VN derivative and option fixtures. +- Role-topology integration test proves scaling API replicas does not increase provider connections or duplicate publication. +- V1 OpenAPI/Redis/SDK golden artifacts are byte/semantic compatible with Phase 0. +- Schema migrations are forward-only, idempotent in clean and existing DB cases, and have backup/rollback evidence. +- Static dependency tests prevent API/control/history modules from importing and starting ingestion ownership accidentally. + +### Completed + +- Not started. + +### Technical Debt / Decision Gate + +- Contract naming or semantics that affect public V2 behavior require explicit approval before schema freeze. Pure implementation details do not. + +### Rollback + +- New roles and schemas remain dark. Existing combined runtime stays authoritative until a later per-feed cutover. + +## 6. Phase 2 - Durable Backbone And Rust Foundation + +**Status:** `PLANNED` + +### Goal + +Introduce a replayable raw/canonical event backbone and a deterministic Rust data-plane foundation without making Rust or the new broker authoritative. + +### Guide Index + +- [Phase 2 detailed guide index: Sections 6-7, 11, 28-29 and Epics E4-E5](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md#implementation-phase-2) + +### To Do + +- Select and document the Kafka-compatible implementation from measured capacity, operational burden, disk budget and recovery requirements. Keep producer/consumer contracts Kafka-compatible. +- Provision isolated raw, canonical, quality and DLQ/quarantine topics with explicit partition keys, retention, replication, quotas and ACLs. +- Implement idempotent publication, deterministic event IDs, retry classification, bounded local spool and feed-state transition when durable commit is unavailable. +- Create a Cargo workspace for contract types, decimal/time utilities, instrument identity, event IDs, adapter traits, broker client, telemetry and replay test tools. +- Implement cross-language golden codecs/checksums and a deterministic venue simulator reusable by Python and Rust. +- Build a shadow raw-to-canonical pipeline for one small, demand-backed slice. The provisional slice is selected Binance USD-M trade symbols, not broad Spot. +- Keep Redis as latest-state/legacy projection only; prove it can be rebuilt from canonical events. +- Add CI gates for formatting, lint, tests, unsafe-code policy, dependency/license/security audits, Buf compatibility and reproducible container artifacts. + +### Verification And Exit Gate + +- Broker restart/failover tests lose no acknowledged canonical events and do not expose non-idempotent duplicate state. +- Same raw fixtures and config/normalizer revision produce identical canonical checksums across repeated replay and across Python/Rust reference implementations. +- Slow/down broker tests prove spool bounds, backpressure and `DEGRADED/BLOCKED` semantics; no silent queue drop is allowed. +- Redis flush/restart followed by replay rebuilds the same latest-state checksum and legacy projection fixture. +- Performance baseline reports p50/p95/p99/p99.9, throughput, CPU, RSS, allocation and disk/network amplification using semantically identical parsing. +- All ephemeral topics, groups, Redis prefixes and volumes created by tests are removed after evidence capture. + +### Completed + +- Not started. + +### Technical Debt / Decision Gate + +- Broker distribution and production topology require user approval if they add material memory/disk/operations cost. +- Phase 2 must not silently substitute Redis Streams as the permanent canonical backbone. + +### Rollback + +- Stop shadow Rust/broker services and remove their isolated resources. Existing Python-to-Redis path remains authoritative. + +## 7. Phase 3 - Scalable Ingestion And Compatibility Projection + +**Status:** `PLANNED` + +### Goal + +Run high-throughput ingestion and canonical projection with explicit shard ownership, demand-driven subscriptions and V1-compatible outputs, initially in shadow and then per-feed authority slices. + +### Guide Index + +- [Phase 3 detailed guide index: Sections 12-14, 20, 23, 37, P2 and Epics E6-E8](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md#implementation-phase-3) + +### To Do + +- Implement Rust Binance USD-M adapter for demanded trade/BBO/bar feeds using capability-based interfaces, validated instrument discovery and exact native sequence/time/decimal extraction. +- Replace configured broad-universe ownership with declared baseline plus TTL demand leases; implement lease/fencing epochs so only one active owner publishes a shard. +- Keep Spot disabled when registry refcount is zero. Add conformance tests showing Spot can be enabled without changing code or namespaces. +- Implement bounded queues by feed class: lossless backpressure/spool for trade/book delta; explicit coalescing only for latest-state-safe projections. +- Add reconnect/resubscribe, rate-limit budget, jittered backoff, heartbeat, gap detection and REST snapshot/resync appropriate to each feed. +- Implement canonical Redis projector plus V1 compatibility projector with checkpointed idempotence, versioned keys and legacy payload snapshots. +- Shadow-compare Python and Rust on event count, IDs, price, quantity, side, timestamps, sequence, bar closure and quality flags before authority changes. +- Provide adapter extension fixtures for OKX and a synthetic Deribit-style option/order-book source to prove capability boundaries without claiming those venues production-ready. + +### Verification And Exit Gate + +- Adapter conformance suite passes normal, malformed, duplicate, out-of-order, gap, reconnect storm, delist and graceful shutdown cases. +- Two-owner fencing test proves stale owner cannot publish after lease loss. +- Burst and sustained load at measured universe size plus headroom produces zero silent loss, bounded memory and controlled broker/Redis lag. +- Python-versus-Rust shadow reports meet exact-field parity; every allowed divergence is versioned and approved. +- Legacy V1/Redis consumers observe no shape, namespace or source-authority regression. +- One low-risk feed slice can switch authority and roll back without restarting unrelated venue/feed shards. + +### Completed + +- Not started. + +### Technical Debt / Decision Gate + +- Venue-specific sequence/checksum limitations must be documented in capability metadata and certification, not hidden with generic assumptions. + +### Rollback + +- Per-feed authority flag returns publication to Python. Rust remains shadow; compatibility projector checkpoints permit deterministic recovery. + +## 8. Phase 4 - Quality, History, Replay And Gap-Free Handoff + +**Status:** `PLANNED` + +### Goal + +Produce auditable, replayable and revision-aware data from raw ingestion through historical warmup and live continuation, with no undetected gap or duplicate at the handoff. + +### Guide Index + +- [Phase 4 detailed guide index: Sections 13-16, 38 and Epics E7/E9](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md#implementation-phase-4) + +### To Do + +- Implement canonical validation levels, duplicate/out-of-order handling, sequence/gap ledger, clock-discipline metrics and failover/source-authority state machine. +- Preserve raw source payload and lineage for governed retention; quarantine malformed/unknown-instrument events instead of coercing invalid values. +- Add S3-compatible object storage and Iceberg/Parquet materialization with immutable data files, atomic snapshots, schema evolution and compaction governance. +- Migrate existing VN canonical 1m and derived intervals without fabrication; preserve session calendars, origin, revision and sparse-market semantics. +- Materialize crypto history/replay only where demand/cost evidence requires it; retain direct bounded REST wrappers for ordinary warmup. +- Implement snapshot plus durable cursor/watermark protocol, cursor persistence and reconnect replay so warmup transitions to live without gap or duplicate. +- Add historical/live reconciliation, bar revision behavior and replay determinism reports keyed by source/config/normalizer versions. + +### Verification And Exit Gate + +- OHLCV oracle tests verify first/max/min/last/sum rules, market-session boundaries, DST/time zones, daily close and late/revised bars. +- Crash tests at file upload/metadata commit boundaries expose either old or new Iceberg snapshot, never partial state. +- Snapshot-cursor tests cover cold start, reconnect, cursor expiration, compaction boundary, late event and consumer restart. +- Historical/live overlap checks produce zero unexplained gaps/duplicates for certified feeds. +- Raw replay produces deterministic canonical checksums and traceable lineage to historical rows and Redis latest state. +- VN real-provider bounded checks distinguish market closed/sparse/late data from outage without synthetic seeding. + +### Completed + +- Not started. + +### Technical Debt / Decision Gate + +- Object-store/catalog deployment and retention cost require approval before production provisioning; local MinIO/catalog remains a test implementation only. +- Provider licensing constraints must be recorded before raw retention is enabled for a new source. + +### Rollback + +- Existing VN Parquet/read path remains available until shadow snapshot reconciliation passes. Historical authority switches per dataset, never globally. + +## 9. Phase 5 - V2 API, SDK And Controlled Consumer Migration + +**Status:** `PLANNED` + +### Goal + +Expose provider-neutral V2 snapshot/query/stream contracts and migrate consumers one `DataRequirement` at a time while V1 remains fully operational. + +### Guide Index + +- [Phase 5 detailed guide index: Sections 17-19, 24-25, 32, P2/P3 and Epics E10-E13](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md#implementation-phase-5) + +### To Do + +- Implement provider-neutral V2 REST snapshot/batch/history endpoints, typed errors, explicit quality/provenance and partial-batch semantics. +- Implement gRPC server-streaming with snapshot cursor, durable replay, backpressure status and consumer telemetry. +- Generate Python SDK V2 from canonical contracts; provide sync/async wrappers, cursor persistence, freshness/source validators and V1 compatibility facade. +- Make `DataRequirement` manifests the audited source for subscription, startup readiness, fallback, revision and warmup needs. +- Integrate one reference alpha-grade and one execution-grade consumer in shadow. Trading System must not need Kafka knowledge. +- Validate current alpha runtime and Trading System V1 behavior unchanged; migrate only explicitly selected consumers after parity evidence. +- Publish deprecation telemetry and owner notifications, but do not remove V1 or legacy Redis in this phase. + +### Verification And Exit Gate + +- OpenAPI/Buf breaking gates and generated-client tests pass in CI. +- End-to-end tests cover venue simulator -> durable log -> canonicalizer -> Redis/V1 and gRPC/V2 -> reference consumers. +- Consumer restart, slow consumer, cursor expiration, fallback activation and revised-bar cases produce documented deterministic behavior. +- V1 and V2 shadow responses match canonical values and differ only in declared metadata/versioning. +- Selected alpha and Trading System consumers pass warmup, latest, stream, reconnect and freshness tests without direct venue connections. +- Load tests prove API replicas scale independently and do not multiply ingestion connections. + +### Completed + +- Not started. + +### Technical Debt / Decision Gate + +- No consumer is forced to migrate without owner acceptance. Sunset dates are a separate governed decision based on telemetry. + +### Rollback + +- Move the selected consumer manifest back to V1/legacy projection. V2 and durable state remain available for diagnosis; no shared contract reversion is needed. + +## 10. Phase 6 - Production Certification And Multi-Venue Readiness + +**Status:** `PLANNED` + +### Goal + +Certify production reliability, security, resource efficiency and operational recovery; complete controlled authority cutover for approved feeds; and prove the architecture can add OKX, DNSE/VN and future Deribit options without core redesign. + +### Guide Index + +- [Phase 6 detailed guide index: Sections 25-29, P3, 34-35, 37-41 and Appendix B](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md#implementation-phase-6) + +### To Do + +- Add OpenTelemetry traces/metrics/log correlation, role/feed dashboards, error budgets and actionable alerts for connection, lag, gaps, quality, projection, history and consumers. +- Enforce network zones, control-plane AuthN/AuthZ, secret handling, egress allowlists, SSRF/payload limits, audit logs and supply-chain/container policies. +- Run chaos matrix: process kill, broker failover, Redis loss/rebuild, projector checkpoint boundaries, DB/object-store outage, network partition, malformed frames, reconnect storm and slow consumers. +- Run sustained and burst performance/soak against measured production load plus headroom; verify CPU/RSS/disk/network and no monotonic memory/lag growth. +- Certify Binance USD-M first; certify OKX and Python VN adapters independently using the common conformance suite and explicit source-authority policies. +- Prove option readiness with instrument discovery, expiry/strike/call-put identity and order-book snapshot/delta/checksum fixtures representative of Deribit. Actual Deribit production activation remains a separate adapter certification, not a core rewrite. +- Cut over authority per venue/market/feed/hash range only after shadow parity and rollback rehearsal. Keep V1 compatibility projector until registered consumer sunset criteria are met. +- Remove obsolete combined-runtime producers and unused broad Spot runtime only after ownership, consumer and rollback gates pass; retain reusable adapter capability. +- Produce immutable artifacts, SBOM/provenance, release notes, runbooks and DR evidence; clean all test infrastructure and generated state. + +### Verification And Exit Gate + +- Every item in [Section 41 production acceptance checklist](upgrade/quant-data-layer-fund-grade-upgrade-architecture.md#41-production-acceptance-checklist) and Appendix B has evidence or an explicitly approved non-applicable rationale. +- Certified feeds meet correctness, freshness, gap, durability, replay, latency and recovery SLOs under normal, burst and failure tests. +- Security scans and AuthN/AuthZ/egress/secret-redaction tests meet policy with no unresolved critical/high issue. +- Capacity report demonstrates safe headroom on the current host or supplies a measured scale-out requirement before cutover. +- Rollback rehearsal restores the previous authoritative producer without data ambiguity. +- Test topics, consumer groups, schemas, Redis prefixes, buckets, volumes and containers are removed; production state remains untouched. + +### Completed + +- Not started. + +### Technical Debt / Decision Gate + +- Actual Deribit, additional options vendors or regional HA are separate production activations requiring credentials, licensing, capacity and source-semantics approval. The core architecture must already support them. +- V1/legacy Redis removal is not part of automatic Phase 6 closure; it requires zero-consumer telemetry and an approved sunset release. + +### Rollback + +- Authority flags roll back per feed/partition to the last certified producer. Durable cursors and canonical data remain available for reconciliation. + +## 11. Approval Gate Before Implementation + +Implementation begins only after the user approves this seven-phase decomposition and the two architecture-guide clarifications: + +1. Use a demand-backed Binance USD-M slice instead of blindly starting with broad Binance Spot. +2. Treat options/Deribit as a first-class capability test now, while deferring actual venue activation until its own certification. + +Upon approval, Phase 0 is implemented first. Later phases may refine measurable thresholds from Phase 0 evidence, but may not weaken compatibility, correctness, no-silent-loss or cleanup gates without explicit approval. diff --git a/README.md b/README.md index f3812a3..8d22c68 100644 --- a/README.md +++ b/README.md @@ -13,6 +13,8 @@ It currently serves: ## Quick Links - [Integration guide](./DATA_LAYER_SERVICE_ACCESS_GUIDE.md) +- [Fund-grade implementation tracker](./DATA_LAYER_UNIFIED_IMPLEMENTATION_PLAN.md) +- [Fund-grade architecture and migration guide](./upgrade/quant-data-layer-fund-grade-upgrade-architecture.md) - [Contributing guide](./CONTRIBUTING.md) - [Security policy](./SECURITY.md) - [Code of conduct](./CODE_OF_CONDUCT.md) diff --git a/upgrade/quant-data-layer-fund-grade-upgrade-architecture.md b/upgrade/quant-data-layer-fund-grade-upgrade-architecture.md new file mode 100644 index 0000000..6283210 --- /dev/null +++ b/upgrade/quant-data-layer-fund-grade-upgrade-architecture.md @@ -0,0 +1,4812 @@ +# Quant Data Layer — Fund-Grade Architecture & Migration Plan + +> **Repository:** `BobbyAxerol/quant-data-layer` +> **Document status:** Proposed target architecture and implementation roadmap +> **Architecture style:** Python + Rust, contract-first, durable event log, backward-compatible migration +> **Primary audience:** Data platform, quant research, alpha, execution, risk, infrastructure, SRE +> **Scope:** Market-data acquisition, normalization, short historical warmup, live distribution, recovery, replay, quality control, SDK and compatibility +> **Out of scope:** Alpha decisions, portfolio logic, risk decisions, OMS/EMS, order routing, broker account state and execution ownership + +--- + +## Document map + +- **Implementation tracker:** [`DATA_LAYER_UNIFIED_IMPLEMENTATION_PLAN.md`](../DATA_LAYER_UNIFIED_IMPLEMENTATION_PLAN.md) translates this architecture into seven gated phases with status, test evidence, rollback and technical-debt decisions. + +- **Sections 0–7:** scope, current state, principles, guarantees, target architecture, Python–Rust split and recommended stack. +- **Sections 8–19:** canonical domain/events, schema versioning, durable topics, venue adapters, quality/fallback, historical, warmup-to-live, API, SDK and alpha integration. +- **Sections 20–29:** service/monorepo decomposition, configuration, Redis compatibility, readiness, observability, security, testing, CI/CD and HA/DR. +- **Sections 30–35:** migration strategy, roadmap P0–P4, compatibility matrix, implementation epics, runbooks and governance. +- **Sections 36–43:** concrete configuration, performance/failure policy, prohibited anti-patterns, ADRs, acceptance checklist and final target state. +- **Appendices:** first production slice, adapter definition of done, non-functional requirements and the seven-phase execution index. + +--- + +## 0.

Control endpoint cũng tự mô tả runtime hiện tại là `combined_api_ingestion_history`. Vì vậy deployment API nhiều replica có thể kéo theo nhiều ingestion owner và duplicate publication. + +Các contract hiện tại phải được xem là **legacy public surface**, không phải nền tảng để tiếp tục mở rộng trực tiếp. + +### 2.2 Constraints bắt buộc + +1. Các alpha hiện tại phải tiếp tục chạy trong khi migration. +2. `/v1` không được thay đổi breaking shape hoặc source semantics mà không có compatibility flag và release notice. +3. Các channel như `stream:trade:*`, `stream:kline:*`, `stream:vn:*` phải tiếp tục được publish trong migration window. +4. Redis key hiện tại phải tiếp tục hỗ trợ recovery cho service cũ. +5. Không yêu cầu mọi alpha cài Kafka client. +6. Không rewrite DNSE/vnstock sang Rust chỉ vì chuẩn hóa ngôn ngữ. +7. Không đưa quá nhiều thay đổi hạ tầng vào cùng một release. +8. Mọi cutover phải có shadow comparison, rollback path và consumer telemetry. +9. Contract mới không được encode assumption chỉ đúng với crypto; phải support equity, futures, perpetual, option, index và vendor/reference source. +10. Venue không được đồng nghĩa với toàn bộ trading system hay toàn bộ data layer. + +### 2.3 Những lỗi cần khóa ngay trước khi mở rộng + +- Không cho spot và futures ghi chung canonical kline namespace. +- Không dùng `market=auto` cho execution-grade flow mới. +- Không coalesce hoặc silent-drop trade/book-delta canonical event. +- Không dùng `float` làm canonical representation của price/quantity. +- Không biến missing/invalid numeric field thành `0` nếu `0` có thể là giá trị thị trường hợp lệ. +- Không cho GET warmup route tự ý thực hiện mutation dài và không có job identity. +- Không cho API replica tự sở hữu venue stream. +- Không cho arbitrary outbound fallback URL từ request. + +--- + +## 3. Architecture principles + +### 3.1 Contract-first, implementation-second + +Public contract, event contract, quality semantics và versioning policy được định nghĩa trước adapter implementation. Python và Rust đều generate type từ cùng source schema. + +### 3.2 Event log khác latest state + +- **Event log** cần durability, replay, ordering và cursor. +- **Latest state** cần đọc nhanh và có thể rebuild. +- **Notification Pub/Sub** có thể mất message nếu consumer offline. + +Không dùng một công nghệ hoặc một key/channel để giả định cả ba semantics. + +### 3.3 Raw, canonical và derived là ba data products khác nhau + +- **Raw:** bảo toàn payload từ source để audit/renormalize. +- **Canonical:** stable typed contract cho trading system. +- **Derived:** bars, snapshots, features hoặc materialized views được tạo từ canonical events. + +Consumer không được đọc raw layer trừ diagnostics/research được cấp quyền rõ ràng. + +### 3.4 No silent loss + +Với lossless feed class như trade hoặc order-book delta: + +- Nếu event không thể commit vào durable log, adapter phải retry/spool hoặc chuyển feed sang `DEGRADED/BLOCKED`. +- Không được tiếp tục báo healthy trong khi drop. +- Mọi loss phải có counter, quality event, incident context và gap record. + +### 3.5 At-least-once transport, effectively-once projection + +Duplicate có thể xuất hiện do retry/replay. Hệ thống dùng deterministic event ID, source sequence, idempotent producer và idempotent projector để đảm bảo state/output không bị áp dụng hai lần. + +### 3.6 Ordering có boundary rõ ràng + +Không cam kết global ordering. Cam kết ordering theo: + +```text +partition_key = instrument_uid + feed_type + source_id +``` + +Với book delta, partition key và source sequence là bắt buộc. + +### 3.7 Source fidelity trước convenience + +Raw decimal, timestamps, source sequence và source identity được bảo toàn. Convenience conversions được thực hiện ở canonical layer với precision rõ ràng. + +### 3.8 Fallback không được trộn âm thầm + +Primary, secondary, reference và backfill là các source role khác nhau. Cross-venue reference data không tự động thay thế authoritative venue data trong execution-grade projection. + +### 3.9 Scale theo workload, không scale toàn bộ service cùng nhau + +- API scale theo request load. +- Ingestor scale theo venue/market/shard. +- Canonicalizer/projector scale theo event partitions. +- History materializer scale theo data partitions/jobs. +- Reconciler scale theo audit workload. + +### 3.10 Backward compatibility là feature bắt buộc + +Legacy projector và compatibility API là thành phần chính thức của migration, không phải temporary hack không có owner. + +--- + +## 4.

Mark affected source/feed `DEGRADED` or `OFFLINE`. +2. Stop advertising `execution_eligible=true`. +3. Verify venue status, DNS, credential, rate limit and local network. +4. Reconnect with bounded exponential backoff and jitter. +5. On reconnect, create new `source_session_id`. +6. Resubscribe from authoritative instrument registry. +7. For sequence-sensitive feed, obtain snapshot and reconcile buffered deltas. +8. Emit recovery/gap records. +9. Promote to `LIVE` only after freshness and gap gates pass. +10. Record incident duration and affected requirements. + +Do not silently switch execution authority to another venue unless source policy explicitly permits it. + +### 34.2 Sequence gap detected + +1. Persist gap ledger record: instrument, feed, expected, observed, source session. +2. Set `gap_open=true`; affected execution requirement blocks. +3. Buffer later deltas only within bounded capacity. +4. Fetch venue snapshot/backfill according to adapter semantics. +5. Rebuild state from snapshot + valid buffered deltas. +6. Verify checksum/sequence continuity. +7. Emit reconciliation result and close gap. +8. If recovery impossible, start new epoch/source session and mark unfillable range. +9. Notify historical materializer of gap/revision. + +Never fill unknown trade/order-book events with fabricated values. + +### 34.3 Kafka produce degradation + +1. Producer stops acknowledging canonical success to upstream processing. +2. Apply bounded in-memory backpressure. +3. Use approved local spool only if configured and disk health permits. +4. Mark feed degraded before buffer exhaustion. +5. Alert broker/platform owner. +6. Resume and drain in source order after broker recovery. +7. Validate source sequence and broker offsets. +8. Reconcile any unacknowledged range. + +If capacity is exhausted, disconnect/resubscribe and record explicit loss/gap rather than overwrite canonical events. + +### 34.4 Kafka partition/rebalance issue + +1. Check leader/ISR and consumer-group assignments. +2. Pause rollout causing repeated rebalance. +3. Ensure old shard owner fenced. +4. Restore healthy broker replica/partition. +5. Restart only affected consumer if necessary. +6. Compare checkpoint with output state. +7. Replay idempotently from safe offset. + +### 34.5 Redis unavailable or lost + +1. Canonical ingestion continues if broker healthy. +2. API marks latest projection degraded; stream v2 from broker remains available if gateway healthy. +3. Restart/fail over Redis. +4. Run projector rebuild to isolated namespace. +5. Validate key cardinality, checksum and freshness. +6. Switch namespace/traffic atomically. +7. Resume legacy Pub/Sub publication. + +Do not backfill missing Pub/Sub messages; legacy consumers must use REST/warmup recovery. V2 cursor consumers replay from durable stream. + +### 34.6 Projector lag above SLO + +1. Identify partition/skew/instrument hotspot. +2. Verify Redis latency and consumer errors. +3. Pause noncritical legacy projections if policy allows. +4. Scale projector consumers within partition constraints. +5. Repartition only through planned topic migration, not emergency arbitrary change. +6. Alpha SDK evaluates projection/stream freshness and blocks if requirement violated. + +### 34.7 Historical snapshot corruption or reconciliation mismatch + +1. Freeze affected snapshot from new readers. +2. Identify last verified Iceberg snapshot. +3. Compare data-file checksums and source/canonical offsets. +4. Roll back reader pointer to verified snapshot if required. +5. Replay/materialize affected partitions to shadow snapshot. +6. Run row-count, OHLCV invariant and source reconciliation. +7. Commit new corrected snapshot with revision metadata. +8. Notify consumers of revised bars/range. + +Never overwrite data files in place. + +### 34.8 Source fallback activation + +1. Primary transitions to degraded/offline. +2. Evaluate `DataSourcePolicy` for feed/consumer grade. +3. Publish `FeedState` and source-role change before or with fallback data. +4. For reference-only fallback, set `authoritative=false` and `execution_eligible=false`. +5. Consumer SDK enforces configured behavior: block, reference, conservative mode or approved failover. +6. On primary recovery, require stability window and reconciliation before switchback. +7. Audit actor/policy/config revision. + +### 34.9 Schema regression + +1. Stop new writer version/canary. +2. Keep old readers and old writer compatible path active. +3. Quarantine unknown/incompatible events; do not poison entire consumer group. +4. Roll back binary/config or deploy forward-compatible reader. +5. Replay quarantined events after fix. +6. Add fixture and Buf/OpenAPI gate to prevent recurrence. + +### 34.10 Consumer cursor expired + +1. SDK receives typed `CURSOR_EXPIRED` error with earliest available cursor. +2. Block execution decision. +3. Request fresh warmup/snapshot and new watermark. +4. Rebuild local state. +5. Subscribe from returned cursor. +6. Resume only after requirement gate passes. + +### 34.11 Bad config rollout + +1. Automatic validation rejects impossible config before activation where possible. +2. Canary config revision applies to limited shard/consumer. +3. On anomaly, set previous config revision active. +4. Fencing ensures stale owner cannot keep publishing. +5. Replay/reproject affected range if semantics changed. +6. Audit before/after revision and reason. + +### 34.12 Full regional recovery + +1. Declare active region unavailable. +2. Fence old region venue ownership where reachable. +3. Promote replicated broker/control/storage dependencies according to DR plan. +4. Acquire venue leases in standby region. +5. Establish new source sessions. +6. Reconcile source gaps from venue historical APIs where possible. +7. Restore query/stream endpoints. +8. Consumers perform snapshot-plus-cursor recovery. +9.

Dynamic prices, quantities and timestamps are not committed. +- Inventory scanned 1,748 workspace source/config files, including 361 Trading System files and 261 active-alpha files. +- Active migrated alpha tree has three SDK integration files and no detected direct Binance/OKX/DNSE/vnstock endpoint imports after excluded logs/state/research data. +- Workspace-wide direct-provider references remain high because legacy alpha trees, provider adapters, broker execution SDKs and research utilities are intentionally present. They are not evidence that each path is an active market-data consumer. +- Trading System still consumes legacy `stream:trade:{symbol}`. The current producer lets Spot and USD-M both project to this alias, so Spot removal is a source-authority cutover requiring V1 parity evidence, not merely a container flag. + +## Runtime Baseline + +Two ten-second windows were captured from the existing service without restart: + +| Metric | Window 1 | Window 2 | +|---|---:|---:| +| HTTP service health | `ok` / `ok` | `degraded` / `degraded` | +| Redis command delta | 42,968 | 45,270 | +| Redis input-byte delta | 19,757,878 | 20,416,067 | +| Redis output-byte delta | 1,474,224 | 1,075,203 | +| Redis evictions/rejected connections | 0 / 0 | 0 / 0 | +| Queue cumulative drops | 3,790,249 | 3,790,249 | +| Queue recent drops | 0 | 0 | + +Window 2 degraded because demand added `kline:binance_usdm:1m:BTCUSDT`, while raw kline publication lost its internal source metadata. The Redis V1 payload itself remained valid. Commit `965275e` fixes supervisor correlation by carrying source as publisher metadata without changing the Redis payload or endpoint response.

Confirm durable storage, Redis shadow namespace and history bucket have safe + capacity. Never reuse a production consumer group for testing. + +## Venue Loss Or Reconnect Storm + +1. Mark only the affected feed `DEGRADED`/`OFFLINE`; remove execution eligibility. +2. Inspect heartbeat age, provider status, DNS, rate budget and credentials. +3. Reconnect with bounded exponential backoff and jitter under connection limits. +4. Create a new source session and resubscribe from the registry snapshot. +5. For sequence feeds, fetch a provider snapshot and reconcile buffered deltas. +6. Close the gap ledger only after sequence/checksum/freshness pass. +7. Restore `LIVE` after the configured stability window. Do not silently promote + a reference source. + +For OKX maintenance notice `64008`, use make-before-break: open a replacement, +subscribe and obtain a fresh book snapshot, switch generation atomically, then +close the old socket. Old-generation frames are discarded. + +## Durable Transport Or Network Partition + +1. Stop acknowledging canonical success while the sink is unavailable. +2. Apply bounded backpressure. Use the approved local spool only while disk and + scope bounds remain healthy. +3. Before capacity exhaustion, mark the feed degraded and disconnect cleanly. +4. After recovery, drain in source order, verify cursor continuity and reconcile + the unacknowledged source range. +5. A missing acknowledged event is SEV-1. Preserve spool and logs as evidence. + +## Redis Loss + +1. Keep durable ingestion running; mark latest projection unavailable. +2. Rebuild to an isolated namespace from canonical events. +3. Compare key count, content checksum and freshness with the previous namespace. +4. Switch projection/API traffic atomically, then restore V1 compatibility + publication. Pub/Sub messages are not backfilled; V1 consumers warm up again. + +## Projector Or Consumer Failure + +1. Compare durable checkpoint with idempotent output before restart. +2. Replay from the last confirmed cursor; duplicate events must not produce a + second visible state transition. +3. A slow stream consumer is disconnected with a typed error. Other consumers + remain live; the slow consumer uses its signed cursor to replay. +4. An expired cursor blocks trading until a new snapshot-plus-cursor handoff. + +## Historical/Object-Store Failure + +1. Never expose uploaded data or manifests before the atomic head update. +2. On upload/commit timeout, retain the old head and classify new objects as + orphans. +3. Verify checksums and lineage, then retry from the old parent snapshot. +4. Purge orphans only after the retention floor and exact dataset confirmation. +5. For corruption, move readers to the last verified snapshot and rebuild a new + immutable revision; do not overwrite files in place. + +## Authority Promotion And Rollback + +Promotion unit is `(environment, provider, venue, market, feed, instrument/hash +range)`. Required gates are contract, correctness, durability, projection, +recovery, compatibility, performance, security and operations. + +1. `OFF -> SHADOW`: no public write authority. +2. `SHADOW -> CANARY`: compare source identity, counts, values, timestamps, + sequence and quality against the current producer. +3. `CANARY -> PRIMARY`: approve only after rollback rehearsal and clean error + budget. Keep V1 compatibility projection. +4. Rollback by fencing the new writer, restoring the old authority flag and + replaying/reconciling the affected cursor range. Never delete a topic or + canonical event to roll back. + +OKX SBE rollback always returns to JSON for the same capability. Unknown SBE +template/version fails closed and cannot fall through to best-effort decoding. + +## Game-Day Matrix + +Exercise and attach evidence for process kill, broker outage, Redis rebuild, +projector checkpoint boundary, object-store commit failure, malformed frame, +sequence gap, reconnect storm, duplicate shard owner, slow consumer and bad +config rollback. Regional DR requires real replicated infrastructure and cannot +be certified by a same-host test. + +## Cleanup + +Remove disposable containers, networks, volumes, test spool files, test Redis +prefixes, consumer groups and generated signing keys.

Python canonical/quality implementation. +25. **Data-plane identity is application-enforced and consumer-bound.** Gateway + authentication is not the sole trust boundary. REST dependencies and gRPC + interceptors verify short-lived workload identity, audience, issuer, + environment and scopes inside the V2 application. The authenticated subject + resolves to one registered consumer manifest; a caller-supplied + `consumer_id`, purpose, grade or execution flag cannot elevate entitlement. +26. **Public V2 payloads are typed and closed.** A public beta response or SDK + model must use feed-discriminated payload types with `extra = forbid`, + generated enums and exact decimal semantics. `dict[str, Any]`, unversioned + provider payloads and ambiguous string enums are restricted to authenticated + diagnostics. `UNSPECIFIED` enum values fail validation rather than selecting + a production default. +27. **Delivery policy follows event lifecycle, not only feed name.** Trade, + order-book delta/snapshot/reset, final bar, bar revision/correction, + source-authority transition and quality-state transition are lossless + canonical events. BBO, ticker and explicitly marked in-progress bar updates + may be coalesced only by a deterministic lifecycle-aware key. A final or + revised bar may never be overwritten by an in-progress update. +28. **Readiness is measured, not declared.** Liveness, process readiness, + dependency readiness, data readiness, authority readiness and per-consumer + eligibility are separate states. A route or runtime role cannot return + `ready` from a phase constant or static manifest when its broker, query + store, cursor signer, catalog, source policy, auth state or projector is + unavailable or outside the approved lag/freshness bound. +29. **Cursor claims bind the complete recovery contract.** Signed cursors bind + environment, authenticated consumer, requirement digest, stream/partition, + snapshot watermark, schema major, partition epoch, source-policy revision, + instrument-catalog revision and expiry. A cursor from a previous + repartition, policy revision, environment or consumer is rejected + deterministically. +30. **Snapshots and checkpoints are immutable facts.** SDKs and services must + not fabricate a placeholder snapshot ID, cursor or watermark. Missing + immutable snapshot identity or a signed resume cursor is a fail-closed + contract error. Execution-grade consumers acknowledge only a contiguous + applied range and persist checkpoints through a consumer-owned durable or + transactional adapter. +31. **Raw lineage preserves exact provider evidence.** The raw-provider envelope + stores the exact received frame bytes, the declared transport transform, + source session and connection generation. `raw_frame_hash` covers exact + bytes at the declared capture boundary; `canonical_payload_hash` covers the + deterministic canonical representation. Re-serialized JSON is not evidence + of byte-for-byte source fidelity. +32. **Replicated durability precedes authority.** A local SQLite WAL, local file + or single-node Redis Stream may support bounded shadow certification, but no + canonical feed becomes the sole production authority until replicated + durable transport, acknowledgements, retention, failover, restore, quotas, + ACLs and cursor recovery are proven on the real deployment topology. +33. **Authority is persistent, compare-and-swap and sink-fenced.** Every + venue/market/product/feed/partition slice has one durable authority record, + monotonically increasing revision and lease epoch. Producers include owner, + slice, authority revision and lease epoch in publication metadata. The + authoritative sink/projector rejects stale or non-owner writes; producer-side + self-checks alone are insufficient against zombie writers. +34. **Partition ownership is stable and versioned.** Canary selection and + subscription sharding operate on stable instrument or durable-partition + identity, never per event. Rendezvous/consistent hashing or a persisted + assignment table limits churn. Any partition-count or hash-function change + creates a new partition-plan epoch with an explicit handoff watermark. +35. **Corrections and revisions are append-only domain events.** Trade busts, + trade corrections, bar revisions, instrument metadata revisions and source + authority revisions reference the superseded event or revision. Historical + state is rebuilt into a new snapshot; canonical history is not silently + mutated in place. +36. **Capacity gates are machine-evaluable.** A report is `PASS` only when every + configured throughput, bytes/s, latency, loss, duplicate, gap, queue, spool, + CPU, RSS, disk and recovery criterion passes exactly or an explicit approved + tolerance is recorded. Tools may not label a result `PASS` when the measured + target is missed implicitly. +37. **An in-process lock is not a distributed handoff proof.** A local lock may + protect one replica, but multi-replica replay-to-live continuity requires a + broker-native cursor/barrier or one active fenced gateway per partition. + Remote durable I/O is not held under one global event-loop lock. +38. **Execution eligibility is derived server-side.** Data grade, authority, + source policy, freshness, completeness, open-gap state and consumer + entitlement jointly determine execution eligibility. A request header or + payload field cannot assert that a response is execution-grade. +39. **Disaster recovery precedes execution dependency.** A critical alpha or + execution service may not depend solely on V2 until broker failover, + PostgreSQL control-state restore, cursor-key rotation, object-store/PITR, + Redis/projector rebuild and authority reconstruction from the audit log have + passed the approved recovery objectives. + ## 3.

V1 requires - no data replay, schema rollback or restart. +- Remove the V2 beta gateway route and stop only dedicated V2 roles. +- Revoke beta credentials and disable/delete beta consumer manifests. +- Delete isolated beta cursor/checkpoint state, Redis prefixes, consumer groups, + containers and networks after evidence capture. +- V1 requires no replay, schema rollback, venue reconnection or service restart. +- If a beta contract defect is found, revoke the affected schema/SDK release, + keep V1 authoritative and issue a new beta contract revision rather than + silently changing semantics in place. ## 12.
