Production processing validates and transforms the complete request before the first JDBC write and then performs all accepted target writes inside one Spring transaction. Only transient Spring data-access failures are retried. A deterministic request failure does not become a retry storm. -## 5. Non-Functional Requirements +When `Idempotency-Key` is absent, existing synchronous behavior is preserved. When the key is present, an authenticated principal is required; the semantic key is normalized, principal-scoped, hashed, protected by a transaction-lifetime PostgreSQL try-lock, and tied to the request digest. Target writes and the durable response ledger commit in one transaction. -### 5.1 Performance Requirements +#### Durable asynchronous intake -#### NFR-PERF-1: CDC Latency +When the disabled-by-default durable-intake feature is explicitly enabled: -- **Requirement**: Change events published within 1 second of database commit -- **Measurement**: Monitor lag between transaction commit and Kafka publish -- **Priority**: P0 +- `POST /api/etl/jobs` durably creates or replays one principal-scoped pending job; +- `GET /api/etl/jobs/{job_record_id}` returns only an owner-scoped status representation; +- responses use `Cache-Control: no-store`; +- successful submissions use `202 Accepted`, `Location`, and `Idempotency-Replayed` metadata; +- malformed, missing, and foreign-owned identifiers share one non-enumerating not-found surface. -#### NFR-PERF-2: ETL Throughput +The protected baseline is intake-only. Worker execution, pagination, polling advice, conditional status, cancellation, and replay are not described as shipped. V2 requires terminal rows to have a null `request_payload`, but protected `develop` has no worker that transitions accepted jobs to terminal state; therefore an enabled intake can retain `PENDING` payloads without a bounded runtime lifetime. This retention boundary is a `known_gap`, and durable intake remains disabled by default until an integrated worker/lifecycle or explicit retention policy proves bounded retention and restart/recovery behavior. -- **Requirement**: Process minimum 1000 records per second -- **Measurement**: Monitor processing time and throughput metrics -- **Priority**: P1 +#### CDC -#### NFR-PERF-3: API Response Time +The CDC service embeds Debezium 3.4 for PostgreSQL logical change capture, exposes start/stop/status/source/target surfaces, and publishes raw Debezium JSON to Kafka for compatibility.

Issue #141 is the accepted reliability remediation path. -#### NFR-SCALE-2: Data Volume +Protected develop durable intake persists request payloads for active rows and has no integrated worker/TTL that guarantees an accepted `PENDING` row becomes terminal. The V2 terminal-null constraint prevents payload retention *after* a terminal transition, but does not itself create that transition or a TTL.

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.

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.

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.

Compare authorized internal hashes/digests, principal namespace, transaction history, target effects, and application SHA.

Stateful identifiers—including Kafka topics/consumer groups, Debezium connector names, replication slots/publications, database schemas/tables, Docker volumes, secret/config keys, and durable artifact paths—require explicit migration and collision evidence. A documentation rename does not move state. +5. Configuration transitions use versioned aliases only when needed. Reads may accept a bounded legacy alias; writes and generated examples use one canonical identifier. Alias use is observable, non-secret, documented, and has a removal criterion. +6. Java package/Maven/artifact/API renames preserve compatibility through deliberate major-version or adapter strategy. Relocated code and coordinates must not produce ambiguous duplicate classes/artifacts. +7. Metrics/traces/log fields preserve continuity through explicit old→new mappings and cardinality review; identifiers containing customer, principal, job, payload, or secret data are not introduced as labels. +8. Migration order is dependency-aware: inventory → accepted mapping → compatibility implementation → dual-read/alias where justified → state migration → verification → canonical write → deprecation → removal. +9. Rollback is defined before cutover and does not rely on destructive force, state overwrite, or hidden dual writers. +10. Active-PR and planned identifiers remain labeled as such in PRD/TRD/Architecture/UML/ERD/API/Operability/Traceability; a new product name never implies state migration already occurred. + +## Consequences + +- Renaming is slower but auditable and recoverable. +- Some historical identifiers may remain intentionally stable until a major compatibility boundary. +- Operators get explicit manifests, warnings, and cutover evidence instead of silent drift. +- Duplicate broker/database/service state and observability fragmentation become tested failure modes. + +## Alternatives rejected + +- **repository-wide search/replace:** ignores external and persisted consumers. +- **rename only display text and claim completion:** leaves runtime truth ambiguous. +- **write both old and new state indefinitely:** creates split-brain and duplicate effects. +- **drop legacy identifiers immediately:** breaks installed environments without evidence. +- **reuse one compatibility alias for every category:** package, config, broker, DB, and metrics require different controls. + +## Failure and recovery + +If inventory is incomplete, migration does not start.
