Solution Overview +## 2. Problem Statement -### 3.1 Core Capabilities +Enterprise data movement fails commercially when any of these are true: -#### 3.1.1 Change Data Capture (CDC) +- a retry duplicates writes or returns a response that was not committed with the data; +- a large batch partially commits before a later record fails; +- asynchronous work disappears with a process restart or cannot be identified by its owner; +- CDC offsets advance before downstream delivery is acknowledged; +- a stop endpoint reports success before an asynchronous engine has actually terminated; +- connector catalogs imply support that runtime code does not provide; +- authentication documentation claims a real trust boundary while the implementation is still a placeholder; +- CI reports green for a generated merge revision while a governance contract requires literal source-head evidence; +- architecture decisions live only in PR descriptions or chat history. -- **Real-time Database Monitoring**: Captures INSERT, UPDATE, DELETE operations from PostgreSQL databases -- **Debezium Integration**: Uses Debezium embedded engine for reliable change data capture -- **Kafka Streaming**: Publishes change events to Kafka topics for downstream processing -- **Minimal Source Impact**: Uses PostgreSQL logical replication (pgoutput) to minimize performance impact +The product therefore treats correctness, durability, provenance, operational truthfulness, and documentation traceability as product requirements rather than internal engineering preferences. -#### 3.1.2 ETL Processing +## 3.

Future Work: Admin Console (v2) +### 4.2 `processed_data` -- The UI should be deployed as a separate frontend (static hosting) or served via the gateway; keep services API-only. -- All management APIs must be protected by JWT + `ADMIN` role. -- Audit logging is required for state-changing actions (pipeline control, configuration changes, role changes). -- Prefer integrating with existing observability backends (Actuator endpoints, Zipkin) instead of introducing bespoke log storage. +The local compose target bootstrap creates `processed_data`; synchronous ETL currently inserts transformed payload text through parameterized JDBC. + +### 4.3 `etl_idempotency_records` + +Required protected-develop columns: + +- `idempotency_key_hash` — SHA-256 hex primary key; +- `request_digest` — SHA-256 exact payload digest; +- `response_body` — committed replay representation; +- `created_at` — durable creation timestamp. + +Raw principal names, raw idempotency keys, and request payloads must not be stored here. + +### 4.4 `etl_job_records` + +Required protected-develop columns: + +- `job_record_id`; +- `principal_scope_hash`; +- `submission_key_hash`; +- `request_digest`; +- `request_payload` while active; +- `job_status`; +- `attempt_count`; +- `failure_code`; +- `created_at` / `updated_at`. + +Lifecycle constraints must keep active-state payload presence consistent and reject unsupported status values. + +### 4.5 Active-PR migrations + +Lease, owner-pagination index, cancellation, replay-lineage, and replay-index migrations belong to the durable-stack active PRs. They are not merged persistence until their predecessor order and direct-base evidence are satisfied. + +## 5. HTTP and Error Requirements + +- HTTP semantics follow RFC 9110 where the product defines status/header behavior. +- Typed ETL API failures follow RFC 9457 and must not include raw internal exception, SQL, secret, payload, or principal data. +- Structured `Idempotency-Key` normalization is aligned to RFC 9651 String syntax while retaining the documented compatibility representation. +- `202 Accepted` durable submission is intentionally noncommittal about worker completion. +- Owner-scoped durable status is `Cache-Control: no-store`. +- A current or future `ETag`/`If-None-Match` implementation remains `active_pr` until PR #146 integrates. + +## 6. Security and Privacy Requirements + +- Default deny at production trust boundaries. +- No hard-coded production bearer token, issuer, key, or client credential. +- No raw credential, token, key, SQL, exception text, or secret in ordinary logs/metrics/client problems. +- PII required for legitimate ETL/CDC use is not blanket-masked. Use purpose-bound authorization, data minimization, encryption, retention limits, and auditable privileged access. +- Agent/model execution never receives a broader GitHub authority simply because deterministic publication is needed. +- Workflow dependencies and installation artifacts are immutable/checksum-bound where the repository policy requires it. +- Use NIST SSDF 1.1 as the finalized secure-development reference; draft successors may inform future changes but do not replace the final baseline without an explicit ADR. + +## 7. Observability and Reliability Requirements + +- Micrometer/Actuator/Zipkin or OpenTelemetry-compatible telemetry must use finite-cardinality dimensions for resource state. +- New cross-service telemetry should adopt OpenTelemetry semantic conventions where applicable. +- No job ID, principal, raw key, payload, lease token, SQL, exception message, or unbounded connector identifier may become an uncontrolled metric label. +- `isRunning`, health, status, and stop responses must represent the lifecycle state they actually prove. +- Crash/restart boundaries must document at-least-once or replay tolerance rather than claim end-to-end exactly once without proof. + +## 8. CI, Test, and Coverage Requirements + +### 8.1 TDD + +Every production defect or new behavior begins with a deterministic RED that reaches the intended production boundary. Import/setup/fixture failures are test defects, not valid RED evidence. + +### 8.2 Coverage + +Owned production code requires zero missed configured statements/lines/methods/branches. Public production APIs require complete beginner-readable documentation. A coverage report is accepted only from the same source revision under review. + +### 8.3 Platform matrix + +The Maven reactor must pass on the supported GitHub-hosted OS matrix (Ubuntu, macOS, Windows) for a merge-eligible source head. Conditional self-hosted runs are useful only when actually executed; a skipped conditional job is not positive evidence. + +### 8.4 exact-head source identity + +Protected develop currently uses default checkout on `pull_request`, so GitHub may run source-executing jobs on the generated merge ref. GitHub documents that `actions/checkout` defaults to `GITHUB_REF`, which is the pull-request merge branch for this event. Therefore aggregate green on current protected workflows may be compatibility-preview evidence but is **synthetic-merge** evidence, not literal source-head evidence. + +PR #121 is `active_pr` and carries explicit source-head checkout/verification for CI/SBOM plus scheduler authority separation. Until integrated, its controls must not be described as protected-develop behavior. + +### 8.5 Required evidence inventory + +Before protected merge, evaluate as applicable: + +- exact source CI/test/coverage; +- Dependency Review; +- SBOM (CycloneDX); +- SAST/Semgrep and other configured code scanning; +- hard security scanner source identity; +- unresolved security/review threads; +- commit statuses; +- migration/rollback and compatibility evidence; +- independent non-author formal approval where explicit CWL/mightyETL governance requires it. + +Queued, pending, missing, skipped-required, stale or predecessor evidence is non-passing. + +## 9. Autonomous Maintenance Technical Contract + +The hourly NVIDIA OpenCode scheduler is `active_pr` in #121 and is not yet protected-develop runtime. Its intended authority topology is: + +- model/source-reading job: read-only GitHub authority; +- deterministic branch publisher: isolated `contents: write` only; +- deterministic PR publisher: isolated `pull-requests: write` only; +- exact-head run authorizer: isolated `actions: write` only; +- independent review and merge: separate authorities. + +`NVIDIA_NIM_API_KEY` is the model credential. `COPILOT_GITHUB_TOKEN` is not an autonomous-development credential. + +A branch write requiring an exact parent uses branch-wide compare-and-swap semantics. File-level Contents API SHA alone does not prove the branch parent was unchanged. Prefer trusted checkout or Git Data tree/commit publication followed by non-forced (`force=false`) ref movement after an immediate live-ref reread. + +A writer conflict freezes only the affected branch for that invocation. It does not justify repository-wide idle time while another safe lane exists. + +## 10. Stack and Compatibility Requirements + +- A stacked PR head must descend from the exact live head of its immediate predecessor. +- Old checks, approvals, reviews, and base snapshots do not transfer to replacement branches. +- Destructive force push, `-X ours`, `-X theirs`, or rewritten fail-first evidence are prohibited as ancestry repair mechanisms. +- Downstream stack work does not become merge-eligible merely because the local PR is mergeable. +- Public HTTP/connector/persistence changes require compatibility and rollback evidence. + +## 11. Packaging, Provenance, and Release + +A release is permitted only from the integrated protected head with all required quality, security, coverage, compatibility, migration, SBOM/provenance, review, and release-acceptance gates satisfied. `CHANGELOG.md` must move relevant Unreleased entries to the versioned release. Published artifacts must be verified after publication. + +## 12. Documentation Requirements + +Canonical families are: + +- `PRD.md`; +- `TRD.md`; +- `ARCHITECTURE.md`; +- `SECURITY.md`; +- `docs/adr/README.md` and ADRs; +- `docs/UML.md`; +- `docs/ERD.md`; +- `docs/API_CONTRACT.md`; +- `docs/THREAT_MODEL.md`; +- `docs/TEST_STRATEGY.md`; +- `docs/OPERABILITY.md`; +- `docs/TRACEABILITY.md`. + +Changes to public API, persisted state, lifecycle, trust boundary, deployment, scheduler authority, or release gates update the affected canonical families in the same PR. + +## 13.

Add numeric service latency/availability targets only with load profile, capacity model, and alert/error-budget ownership. + +## 4. Health and readiness + +- Process liveness must not be confused with dependency readiness. +- ETL readiness for target-write traffic should prove required target/database dependencies for the enabled path. +- CDC readiness should distinguish service process health, source configuration, engine task state, and downstream publication readiness. +- `known_gap`: current CDC stopped-state observability can precede graceful Debezium Future completion; issue #141 owns repair. +- Gateway readiness must fail closed when the selected identity mode lacks its required trust material once #142 integrates. + +## 5. Start/stop/restart + +### ETL + +Synchronous requests rely on database transactions. A process termination before commit must not be reported as a committed success. Durable idempotency/job state allows later replay/status recovery according to the stored contract. + +### CDC + +`start()` uses a dedicated single-thread executor and supports restart after `stop()` on protected develop. Application shutdown closes the engine, shuts down the executor, and waits up to its bounded termination period before forceful shutdown. + +Ordinary `stop()` currently does not wait on the captured task Future. Operators must treat this as a known reliability gap until issue #141 integrates. + +## 6. Backup and disaster recovery + +### PostgreSQL + +Backups must include, according to deployed scope: + +- target business data; +- `etl_idempotency_records`; +- `etl_job_records` and all integrated later migrations; +- schema/Flyway history. + +Recovery verification must test ledger/job referential/lifecycle constraints and avoid replaying a response ledger against target data restored to a different logical point without an explicit reconciliation plan. + +### CDC offsets/schema history + +The embedded engine uses configured offset and schema-history storage. Treat these files as continuity state. Backup/restore must be paired with source WAL/slot retention assumptions; restoring stale offsets can replay events and must be consumer-safe. + +### Kafka + +Topic durability/retention/replication are deployment-owned. mightyETL must not claim broker durability beyond the configured cluster and acknowledged producer semantics. + +## 7. Rollback principles + +- Never modify an already-applied Flyway migration in place; add a reviewed migration/recovery action. +- Stop serving an API that emits/depends on a new lifecycle state before rolling back to binaries that cannot deserialize/handle it. +- A database rollback across cancellation/replay lineage must preserve or deliberately archive evidence first. +- External warehouse/file/API/message effects require connector-native compensation/idempotency; database rollback alone cannot reverse them. +- Scheduler/workflow rollback must preserve branch protection and independent review; do not solve an automation incident by widening tokens. + +## 8. Incident classes + +### ETL atomicity incident + +Freeze affected writes, preserve exact request/revision/transaction evidence, compare accepted rows with committed rows, identify whether a connector escaped the local transaction, and restore from an evidence-backed point rather than replay blindly. + +### Idempotency divergence + +Do not log raw keys while diagnosing. Compare authorized internal hashes/digests, principal namespace, transaction history, target effects, and application SHA. Reconcile target and ledger together. + +### Durable job lifecycle incident + +Pause intake/worker as appropriate, preserve job row and migration state, inspect lease/lifecycle constraints, and do not manually coerce terminal state without understanding transactional target effects. + +### CDC lag/delivery incident + +Inspect source slot/WAL lag, engine task state, Kafka producer/broker state, and downstream idempotency before resetting offsets. Do not delete offset state as a generic retry mechanism. + +### Authentication incident + +Protected develop's placeholder token filter is not an acceptable production identity boundary. For #142 deployments preserve issuer/JWK/audience/algorithm configuration evidence and deny-mode behavior without logging bearer values. + +### Autonomous-agent incident + +Disable candidate publication/authorization at the narrow deterministic writer layer while preserving read-only evidence collection. Revoke/rotate only credentials proven affected. Preserve exact branch/ref/workflow SHA and candidate bundle provenance. + +## 9.

Therefore runtime terminal clearing is **not** a shipped protected-develop execution capability, and an enabled intake can retain a pending payload indefinitely if no worker consumes it.

Those names are conceptual or external unless a protected migration states otherwise; no table was invented to satisfy the ERD request. -All work below remains unshipped and must stay visibly `active_pr`, `planned`, or `known_gap` rather than being omitted or promoted to protected truth: - -- PR #155 — retire abandoned local-auth tables from new clean installations with explicit existing/private-consumer compatibility; -- PR #156 — remove the misleading Qlik row-write scaffold from production discovery/configuration; -- PR #157 — establish checked-in machine-readable OpenAPI/AsyncAPI contracts without advertising active-PR lifecycle behavior; -- PR #158 and PR #163 — remove nonfunctional MySQL and SQL Server Debezium scaffolds from production discovery; -- PR #160 — establish the shared Jackson 2.21.5 baseline for CVE-2026-54515, CVE-2026-59889, and GHSA-mhm7-754m-9p8w without suppressing findings; -- issue #161 — replace the independently reachable ETL HTTP Basic boundary with supported direct/east-west service authentication; -- issue #162 / PR #164 — make JaCoCo non-vacuous and prove a real production class set before any 100% claim; -- issue #165 — bind exact protected source, packages, SBOM, provenance, reproducibility, attestation verification, publication authority, rollback, and release acceptance; -- issue #166 / PR #167 — restore Zipkin internal 9411 while preserving explicit host compatibility; -- issue #168 / PR #169 — remove opaque runtime bootstrap, mutable remote scripts, duplicate launch authority, and tracked binary follow-through; -- PR #170, PR #171, PR #172, PR #174, PR #176, and PR #211 — harden diagnostic confidentiality across controller, loader, CDC, parser, DDL/row and DLT boundaries; -- PR #184 — establish Flyway-only production schema mutation authority; -- PR #189 — require explicit fail-closed Config Server repository authority; -- PR #191 — inventory runtime/Kafka/Debezium/config/state identifier compatibility before product-name migration; -- PR #192 and PR #197 — govern dead-letter privacy and terminal routing; -- PR #199 — reject invalid amount-like values fail-closed; -- PR #201 — make CDC connector registry identity collision-safe; -- issue #196 — reject Maven security evidence built from an unresolved dependency graph; -- issue #205 — prove repository-wide owned-production coverage rather than only focused class bundles; -- PR #208 — bind PostgreSQL backup/restore to exact provenance without inventing disaster-recovery attainment; -- PR #222 and PR #228 — preserve structured record snapshot integrity at mutable/hostile object boundaries; -- PR #224, PR #226, and PR #230 — make public bootstrap and environment/configuration APIs beginner-readable without changing behavior. - -The legal/release boundary remains unresolved: issue #151 requires an explicit owner-approved licensing/copyright decision. Automation must not invent a root license merely to make packaging or documentation appear complete. - -Issue #159 is `planned` follow-through for live documentation coverage and traceability. It is not a substitute for updating canonical docs when relevant implementation changes. - -## ADR sufficiency - -The eight foundational ADRs provide a coherent baseline, but they are **not sufficient for the whole current conversation and live repository** unless the following durable decisions are explicitly absorbed into existing ADRs or recorded in new, non-colliding ADRs after checking active-PR reservations: - -1. one production schema mutation authority and Flyway migration/rollback/recovery semantics; -2. service, registry, Config Server, gateway, and direct/east-west identity authority; -3. diagnostic confidentiality and stable non-sensitive error contracts; -4. DLT payload/header retention, access, encryption, deletion, terminal routing, redrive, and replay authority; -5. non-vacuous focused and repository-wide quality evidence plus source/revision/evidence-channel separation; -6. complete dependency-graph scanner evidence and fail-closed supply-chain acceptance; -7. release/SBOM/provenance/reproducibility/licensing/NOTICE/publication authority; -8. runtime identifier and stateful compatibility migration; -9. backup, restore, destructive-loss recovery, external-side-effect reconciliation, and measured RPO/RTO authority; -10. tenancy choice and principal/tenant/data-residency/retention/deletion boundaries. - -Adding filenames without decisions is not completion. Each ADR must state context, alternatives, decision, consequences, failure/recovery, migration/rollback, security/data-governance impact, tests/acceptance, and supersession conditions. - -## UML and ERD sufficiency - -`docs/UML.md` is structurally useful but `partial`. It must eventually add or update source-backed diagrams for: - -- direct client→ETL, gateway→ETL, service-registry, Config Server, and CDC control-plane identity flows; -- schema mutation and Flyway migration/rollback/recovery authority; -- DLT publication, retention, terminal routing, redrive/replay and authorization; -- PostgreSQL backup→manifest verification→destructive-loss replacement→clean restore→application/invariant validation; -- exact source→scanner/SBOM/review→merge→protected-develop operational acceptance→release authority; -- runtime identifier migration and stateful compatibility; -- degraded modes and failure-domain boundaries. - -`docs/ERD.md` remains accurate for the protected physical tables and active durable-job overlays, but is `partial` as a data-governance model. It must reconcile clean-install legacy-auth retirement, tenant/principal authority, pending payload retention, replay lineage once exact migrations stabilize, DLT/recovery artifact ownership where mightyETL actually persists them, and conceptual/external ownership labels. Do not invent tables merely to satisfy an ERD request; non-relational backup bundles, manifests, Kafka/DLT state, and external warehouses belong in a clearly labeled logical artifact/data model unless a real migration introduces persistence. - -## Remaining cross-cutting documentation authority - -The spine is necessary but file count alone is not sufficient. Each category below needs either a dedicated canonical document or a clearly discoverable index to one authoritative equivalent: - -1. roadmap/lifecycle status and dependency-ordered exit criteria; -2. data governance, privacy, retention, principal/tenant authority, deletion and DLT evidence; -3. migration, rollback, forward recovery, downgrade, identifier migration and compatibility policy; -4. release, versioning, SBOM/provenance, reproducibility, licensing/NOTICE, publication and rollback evidence; -5. standalone/MSA deployment profiles, optional versus required dependencies and failure domains; -6. standards/research doctoring with APA 7 references linked to decisions and tests; -7. connector support matrix distinguishing production, scaffold, removed-from-discovery and planned integrations; -8. SLI/SLO targets versus actually measured attainment, including RPO/RTO; -9. acquisition-diligence controls covering security, rights, dependency obligations, recovery, data authority and residual known risks; -10. identity/trust-boundary authority distinguishing gateway, direct/east-west ETL, Eureka, Config Server, CDC and operator identities; -11. quality/evidence semantics distinguishing literal source, synthetic merge, complete/incomplete dependency graphs, focused/repository-wide coverage, and vacuous/non-vacuous evidence; -12. repository-runtime and observability supply-chain authority, including third-party binaries/images and supported startup paths; -13. backup/restore/recovery acceptance and external side-effect reconciliation; -14. data classification and terminal lifecycle for DLT, request payloads, snapshots, logs, metrics and backup artifacts. - -These categories may be satisfied by existing canonical sections if indexed and machine-checkably discoverable. They are not complete merely because an issue or PR body describes them. - -## Documentation completeness gate - -The minimum canonical graph remains: - -1. `PRD.md` -2. `TRD.md` -3. `ARCHITECTURE.md` -4. `SECURITY.md` -5. `docs/adr/README.md` plus detailed ADRs -6. `docs/UML.md` -7. `docs/ERD.md` -8. `docs/API_CONTRACT.md` -9. `docs/THREAT_MODEL.md` -10. `docs/TEST_STRATEGY.md` -11. `docs/OPERABILITY.md` -12. `docs/TRACEABILITY.md` -13. `docs/DOCUMENTATION_ASSESSMENT.md` -14. discoverable authorities for migration/rollback/recovery, data governance/privacy/retention, release/provenance/licensing, connector support, standards/research, and acquisition diligence -15. `AGENTS.md`, `CLAUDE.md`, `README.md`, and `CHANGELOG.md` aligned to those contracts - -A future feature that changes a public API, persisted state, security/trust boundary, lifecycle state machine, deployment topology, autonomous-authority topology, compatibility promise, or merge/release evidence contract must update the relevant canonical family in the same pull request. Newly opened material PRs/issues must be reconciled during the next stable documentation update. +## Remaining completion conditions -## Overall conclusion +The whole documentation graph remains insufficient on protected `develop` until all applicable conditions hold: -- **Document breadth:** strong on PR #149; insufficient on protected `develop`. -- **PRD/TRD/Architecture depth:** substantial, but stale relative to post-169 work. -- **ADR coverage:** foundational but partial. -- **UML coverage:** useful, but partial for identity, DLT, recovery, schema and release authority. -- **ERD/data model:** truthful for protected persistence, partial for current lifecycle and artifact governance. -- **Traceability:** reconciled on this active documentation branch through current post-169 work; not protected truth until merge. -- **Acquisition-ready documentation:** not yet sufficient. +1.
