regenerating the Prisma client for the new operation models +- Risks: + - cluster operations are now durable and queryable, but execution is still process-local in-memory orchestration, so restart-resume semantics remain future work + - remote node ACKs still rely on authenticated HTTP responses rather than mTLS-backed service identity or a separate ACK callback channel + - only the current reload and certificate-sync workflows use the operation journal so far; additional cluster-wide mutations still need to adopt the same contract in later sessions +- Follow-up sessions: + - Session 13 — implement staged NGINX config generation and atomic activation + - Session 17 — rework cluster certificate distribution and activation + - Session 22 — add cluster operations and node-status admin APIs + - Session 25 — expand metrics and alerting +- Notes: + - added durable `ClusterOperation` and `ClusterOperationAck` tables so cluster-wide mutations can be tracked independently from lease state + - introduced `ClusterOperationsService` to create operation records, pre-register per-node ACK rows, execute local and remote work, and summarize final success/partial-failure state + - changed `POST /cluster/reload` to return `202 Accepted` with an operation ID and added `GET /cluster/operations` plus `GET /cluster/operations/:operationId` for inspection + - updated cluster-triggered certificate sync broadcasts to use the same operation journal, and the per-node sync endpoint now returns HTTP 500 for tracked failures so remote ACK state is

assessment identified two closely related certificate risks: + +1. domain input was weakly validated, which left room for malformed FQDNs, wildcard/path confusion, and unsafe filesystem path derivation +2. certificate and TLS workflows still built OpenSSL and certbot commands through shell-interpolated strings, which increased command-injection risk and made argument handling brittle + +These problems affected certificate issuance, upload, self-signed generation, TLS inspection helpers, generated NGINX certificate paths, and backup archive naming. + +### Decision + +Adopt the following certificate-domain and certificate-process policy: + +1. normalize certificate-related domains to lowercase ASCII/punycode before use +2. accept only fully-qualified domains; reject local-only names, IPs, path separators, whitespace, and control characters early +3. accept wildcard domains only in the left-most `*.` form, and explicitly reject wildcard issuance in the current built-in ACME flow until DNS-01 support exists +4. derive certificate storage paths from deterministic safe storage identifiers instead of raw domain strings +5. execute OpenSSL, certbot, and NGINX helper commands in the certificate/TLS path through `execFile`-style argument arrays rather than shell-interpolated command strings + +### Consequences + +- certificate uploads, self-signed generation, TLS inspection, and route-param-based domain workflows now fail fast on malformed input before they reach filesystem or subprocess boundaries +- wildcard certificate issuance remains intentionally unavailable in the current HTTP-01 flow, which makes the limitation explicit until Session 18 lands a wildcard-safe ACME strategy +- generated NGINX certificate paths, local certificate directories, and backup archive paths no longer depend on raw domain text, reducing path-confusion risk +- future certificate lifecycle work should build on the shared normalized-domain utilities and

safe certificate storage names in generated NGINX config + - ran `npm run typecheck`, `npm test`, and `npm run build` successfully after landing the domain-validation and process-execution changes + -

strategy for clustered production + - Session 19 — encrypt private key material at rest + - Session 20 — harden backup, export, import, and restore flows + - Session 26 — expand automated regression coverage further +- Notes: + - domain handling now enforces lowercase normalized FQDNs with punycode conversion, explicit wildcard rules, and early rejection of path separators, whitespace, control characters, and IP addresses + - certificate storage directories now derive from safe deterministic storage IDs instead of raw domain strings, preventing wildcard/path characters from leaking into filesystem layout or generated NGINX certificate paths + - OpenSSL, certbot, and NGINX invocations in the certificate and TLS flows now use argument arrays via a shared `execFile`-based helper instead of shell-interpolated command strings + - route params and certificate DTO domain arrays are validated and normalized before the certificate services run, reducing the chance of malformed input

Session 9 adds durable audit logging for privileged and mutating operations, including successful writes, denied privileged attempts, and controller/service failures on protected routes. Session 23 now adds dedicated security administration APIs for secret-health review, access review, API-key rotation planning, private-key re-encryption maintenance, and the future internal-certificate rotation contract.

Audit events persist: - -- actor identity -- action name -- target identifier or label when available -- outcome (`success`, `failure`, or `denied`) -- HTTP status and request path -- correlation ID and timestamp - -Readiness now returns **HTTP 503** when critical dependencies are unhealthy. The readiness body also reports the status of: - -- PostgreSQL connectivity -- NGINX master-process health -- last successful config apply -- last successful certificate sync - -### Current authorization matrix - -| Role / actor | Intended scope | -| ---------------- | -------------------------------------------------------------------- | -| Public | health probes, metrics, ACME challenge serving | -| `viewer` | read-only admin inspection endpoints | -| `operator` | runtime operations such as reload, renew, and log inspection | -| `security-admin` | certificate/key management, encrypted backup/import/restore, TLS hardening | -| `platform-admin` | full admin access including cluster maintenance endpoints | -| `internal-node` | internal certificate sync and future node-only control-plane actions | - -### Certificate Endpoints - -| Method | Endpoint | Description | Required role / actor | -| ------ | ------------------------------------ | --------------------------------- | ----------------------------------- | -| GET | `/certificates` | List all certificates with status | `viewer` | -| GET | `/certificates/:id` | Get certificate details | `viewer` | -| POST | `/certificates/upload` | Upload custom certificate | `security-admin` | -| POST | `/certificates/generate-self-signed` | Generate self-signed cert | `security-admin` | -| POST | `/certificates/renew/:id` | Renew specific certificate | `operator` | -| POST | `/certificates/renew-all` | Renew all certificates | `operator` | -| DELETE | `/certificates/:id` | Delete certificate | `security-admin` | -| GET | `/certificates/validate/:domain` | Validate domain | `viewer` | -| GET | `/certificates/health/ocsp-check` | Inspect OCSP support status | `viewer` | -| POST | `/certificates/sync` | Trigger certificate sync | `internal-node` or `platform-admin` | - -### Backup Endpoints - -| Method | Endpoint | Description | Required role | -| ------ | --------------------------------- | ------------------- | ---------------- | -| POST | `/certificates/backup` | Create backup | `security-admin` | -| GET | `/certificates/backup` | List backups | `security-admin` | -| GET | `/certificates/backup/:filename` | Download backup | `security-admin` | -| POST | `/certificates/backup/:filename/verify` | Verify encrypted backup integrity | `security-admin` | -| POST | `/certificates/backup/:filename/restore` | Restore from encrypted backup | `security-admin` | -| DELETE | `/certificates/backup/:filename` | Delete backup | `security-admin` | -| POST | `/certificates/backup/import` | Import certificates | `security-admin` | -| GET | `/certificates/backup/export/:id` | Export decrypted certificate PEMs | `platform-admin` | - -### Metrics Endpoints - -| Method | Endpoint | Description | Auth | -| ------ | --------------- | ------------------ | ------ | -| GET | `/metrics` | Prometheus metrics for health, leases, operations, certificates, and backups | Public | -| GET | `/metrics/json` | JSON metrics with per-section collection status and errors | Public | - -### Logs Endpoints - -| Method | Endpoint | Description | Required role | -| ------ | -------- | ----------- | ------------- | -| GET | `/logs` | Return recent in-memory operational log entries and raw JSON log lines for the current process | `operator` | - -Operational logs now emit structured JSON to stdout for platform log shipping.

The most relevant auth env vars are: - -- `API_KEY` — temporary legacy compatibility credentials -- `AUTH_JWT_SECRET` — enables locally signed HS256 bearer tokens and `/auth/token` -- `AUTH_JWT_PUBLIC_KEY` — optional RS256 verification key for externally issued bearer tokens -- `AUTH_JWT_ISSUER` — expected token issuer and local token issuer -- `AUTH_JWT_AUDIENCE` — expected token audience and local token audience -- `AUTH_DEFAULT_ADMIN_ROLES` / `AUTH_DEFAULT_ADMIN_SCOPES` — bridge claims applied to legacy API keys during the migration from shared keys to bearer-token identities - -Session 23 also formalizes the current rotation expectations: - -- rotate `API_KEY` outside the app by updating the injected secret/config and redeploying every node; use `POST /security/rotate/api-key` to validate the candidate and generate a safe overlap plan -- rotate certificate master keys by changing `PRIVATE_KEY_ENCRYPTION_KEY_VERSION` plus the injected `PRIVATE_KEY_ENCRYPTION_MASTER_KEY`, then calling `POST /security/rotate/private-key-encryption` -- rotate backup-envelope keys by changing `BACKUP_ENCRYPTION_KEY_VERSION` plus `BACKUP_ENCRYPTION_KEY`, then re-creating fresh backup artifacts - -Example migration flow: - -```bash -# Exchange a legacy API key for a short-lived bearer token -JWT=$(curl -s http://localhost:3000/auth/token \ - -X POST \ - -H "X-API-Key: $API_KEY" | jq -r '.accessToken') - -# Use the bearer token for subsequent admin requests -curl http://localhost:3000/auth/me \ - -H "Authorization: Bearer $JWT" -``` - -### Health Endpoints - -| Method | Endpoint | Description | Auth | -| ------ | ----------------- | ------------------------------------------------------------------------- | ---------- | -| GET | `/health/live` | Liveness probe; returns 200 while the process is alive | Public | -| GET | `/health/startup` | Startup probe; returns 503 until first config apply + cert sync succeed | Public | -| GET | `/health/ready` | Readiness probe; returns 503 when DB/NGINX/config/cert state is unhealthy | Public | -| GET | `/health/dependencies` | Dependency drilldown for DB, NGINX, config apply, and certificate sync | Public | -| GET | `/health/deep` | Combined liveness/startup/readiness/dependency report for incident triage | Public | -| GET | `/health` | Legacy alias for `/health/live` | Public | -| GET | `/ready` | Legacy alias for `/health/ready` | Public | -| POST | `/reload` | Reload NGINX config | `operator` | - -### ACME Challenge Endpoint - -| Method | Endpoint | Description | Auth | -| ------ | ------------------------------------ | ------------------------- | ------ | -| GET | `/.well-known/acme-challenge/:token` | Serve ACME challenge data | Public | - -### ACME Challenge Operations - -| Method | Endpoint | Description | Auth | -| ------ | ------------------------- | -------------------------------------------------------------- | -------- | -| GET | `/certificates/challenges` | Inspect recent ACME challenge publication / cleanup lifecycle | `viewer` | - -**📖 API documentation status:** a refreshed API reference is still pending; for now, use the controller source under `src/`, `IMPLEMENTATION_STATUS.md`, and `PRODUCTION_READINESS_ASSESSMENT.md` as the current references. - ---- - -## 🔐 Certificate Management - -### Automatic Let's Encrypt - -Certificates are automatically obtained and renewed for proxy entries with `ssl = true`. - -```sql --- Enable SSL for a proxy entry -UPDATE "ProxyEntry" -SET ssl = true -WHERE id = 1; -``` - -The system will: - -1.

Auto-renew when within `RENEW_BEFORE_DAYS` threshold - -Certificate domain input is now normalized and validated strictly before any filesystem or process interaction: - -- domains must be fully-qualified (`example.com`, not `localhost`) -- internationalized domains are normalized to ASCII/punycode -- wildcard domains must use the left-most `*.` form -- path separators, whitespace, control characters, and shell metacharacter tricks are rejected early -- wildcard issuance remains intentionally unsupported in the hardened built-in ACME flow because production issuance should not require DNS TXT changes - -### ACME strategy selection - -Session 18 formalizes ACME challenge handling behind an explicit strategy layer. - -The runtime supports two `ACME_CHALLENGE_STRATEGY` modes: - -- `auto` *(default)* — use the built-in HTTP-01 flow -- `http-01` — force the built-in database-backed HTTP-01 flow - -This Session 18 implementation is intentionally HTTP-01 only so clustered production issuance works without operator DNS TXT changes. Wildcard orders are rejected early with a clear validation error. - -#### Built-in HTTP-01 strategy - -The hardened HTTP-01 flow is the default for non-wildcard orders and remains cluster-safe: - -1. the issuing node starts an in-process ACME order through the NestJS `AcmeService` -2. the HTTP-01 challenge token + key authorization are written into PostgreSQL together with order/strategy metadata -3. any node can answer `/.well-known/acme-challenge/:token` from the shared database record -4. challenge verification happens in-process before the ACME order is completed -5. the certificate service finalizes the challenge lifecycle as `validated` or `failed`, which makes challenge publication / finalization inspectable after the run - -The `GET /certificates/challenges` endpoint exposes recent built-in HTTP-01 challenge records with statuses such as `presented`, `cleaned-up`, `validated`, `failed`, and `expired`. - -### Private-key storage model - -As of Session 19, the database no longer stores certificate private keys as plaintext PEMs for active certificates or certificate artifacts. - -- `Certificate.keyPem` and `CertificateArtifactVersion.keyPem` now contain encrypted payloads rather than raw PEM text -- per-record `keyEncryption` metadata stores the envelope version, provider type, master-key version, and ciphertext parameters needed for decryption/rotation -- runtime workflows decrypt private keys only when they need to validate material, write local `privkey.pem` files, create backups, or serve explicit export flows - -That means order-history APIs still avoid raw key exposure, while the storage layer now has a clear path for future master-key rotation and external key-manager integration. - -### Backup and restore protection model - -Session 20 moves backup artifacts themselves onto a hardened envelope format: - -- backups are written as encrypted `.lyttlebackup` artifacts instead of plaintext ZIP files -- the encrypted payload contains the familiar logical entries (`certificates.json`, `metadata.json`, `certs/.../fullchain.pem`, `certs/.../privkey.pem`), but those entries are only available after successful decryption -- every backup includes a signed manifest with per-entry SHA-256 checksums, and restore refuses to import anything unless the manifest signature, decrypted payload, and entry digests all verify cleanly -- direct import still exists for explicitly supplied certificate payloads, but each entry is now validated for PEM structure, private-key match, certificate SAN/CN coverage, and validity-window consistency before it is accepted -- raw certificate export is treated as a higher-risk break-glass flow and is now restricted to `platform-admin` -- Session 23 adds `GET /security/status`, `GET /security/secrets/health`, and `GET /security/access-review` so operators can inspect whether the backup and private-key protection inputs are present before attempting high-risk maintenance - -### Break-glass procedures - -Session 23 adds an explicit operator-facing break-glass note instead of leaving these actions implicit: - -- use `GET /certificates/backup/export/:id` only for time-bound emergency recovery that truly requires decrypted PEM material -- prefer encrypted backup verify/restore flows and bearer tokens for normal operations -- record the reason for any break-glass action, review `GET /audit` afterward, and rotate/re-issue credentials if exposed material may have been copied outside the platform -- follow the detailed runbook in `docs/runbooks/security-break-glass.md` - -Example configuration snippets: - -```bash -# Default production strategy: shared HTTP-01 without DNS TXT changes -ACME_CHALLENGE_STRATEGY=auto - -# Force the built-in database-backed HTTP-01 flow -ACME_CHALLENGE_STRATEGY=http-01 -ACME_HTTP01_PROPAGATION_SECONDS=5 - - -# Optional explicit ACME account key location -ACME_ACCOUNT_PRIVATE_KEY_PATH=/app/state/acme/account.pem -``` - -### Certificate order state machine - -Session 16 adds a durable certificate-order workflow so issuance is no longer just an ephemeral ACME subprocess plus a best-effort database write. - -Current order states are: - -- `requested` -- `challenge-published` -- `validating` -- `issued` -- `distributing` -- `activated` -- `failed` -- `revoked` - -Each order now stores: - -- normalized domains and primary domain -- source type (`acme`, `uploaded`, `self-signed`, `imported`) -- attempt and retry counters -- next retry time for failed ACME orders -- per-order event history -- certificate artifact versions linked to the order - -The order read APIs intentionally return metadata and history only;

-**Current caveats:** - -- global mode is the intended target architecture -- Session 6 replaces public-IP autodiscovery with explicit `CLUSTER_CONTROL_ADDRESS` / `CLUSTER_CONTROL_PORT` registration -- Session 10 replaces leader advisory-lock ownership with a durable `ClusterLease` record and generation-based fencing token -- Session 12 adds durable `ClusterOperation` and `ClusterOperationAck` tracking so cluster-wide reload/sync flows return operation IDs and per-node convergence state -- Sessions 7-8 add request identity plus explicit RBAC, but internal-node traffic is still plain HTTP and mTLS remains future work -- the current assessment still identifies remaining P0/P1 blockers in full lease-backed heartbeat reconciliation, cluster ACK tracking, certificate lifecycle hardening, internal-traffic security, and transactional config rollout even after the completed health, auto-recovery, inter-node addressing, auth/RBAC, audit logging, and lease-foundation sessions -- use the swarm manifest for evaluation and development feedback, not as a final production deployment contract yet - -The current container model is intentionally **fail-fast**: if either the NestJS control-plane process or the foreground NGINX master exits unexpectedly, the container exits non-zero so Docker or Swarm can restart it instead of leaving the node wedged. - -The current Swarm manifest now treats peer communication as an **advertised control-plane endpoint** problem: - -- `PORT` remains the internal NestJS listen port inside the container (`3000` by default) -- `CLUSTER_CONTROL_PORT` is the peer-facing port other nodes should call (`3003` in the current host-published Swarm example) -- `CLUSTER_CONTROL_ADDRESS` is the routable hostname/address peers should use for this node (`{{.Node.Hostname}}` in the current example) -- nodes register that advertised endpoint in the database and cluster broadcasts now use that registration instead of building URLs from discovered public IPs - -Leader election now uses a durable database lease: - -- `CLUSTER_LEASE_TTL_SECONDS` controls how long the leader lease remains valid without renewal (default `30`) -- `CLUSTER_LEASE_RENEW_INTERVAL_MS` controls how frequently the local leader renews that lease (default: one third of the TTL, minimum `1000ms`) -- the active lease carries a monotonically increasing generation number that acts as the leader fencing token for later cluster operations - -Cluster-wide mutations now use a durable operation journal: - -- `POST /cluster/reload` now returns `202 Accepted` with an operation ID instead of only reporting local-node success -- `GET /cluster/operations` returns recent cluster operations and summary counts -- `GET /cluster/operations/:operationId` returns per-node acknowledgement state for a specific operation -- `GET /cluster/operations?nodeId=&type=` filters the operation journal down to the node and workflow an operator is investigating -- internal certificate-sync broadcasts also use the same operation journal so later certificate activation work can build on a shared ACK model - -Session 22 adds operator-focused cluster inspection APIs on top of that journal: - -- `GET /cluster/status` returns a single overview payload containing cluster counts, leader/lease health, active nodes, and recent operations -- `GET /cluster/nodes?includeInactive=true` includes stale/inactive nodes instead of only the currently active set -- `GET /cluster/nodes/:nodeId` returns node detail plus recent per-node operation history, config state, and certificate state -- `GET /cluster/nodes/:nodeId/config` returns the latest reload ACK for that node and, on the local node, the current/last-known-good NGINX runtime release metadata -- `GET /cluster/nodes/:nodeId/certificates` returns the latest certificate activation/sync ACKs for that node and, on the local node, a summary of the current certificate inventory from the shared database - -Transactional config activation now uses a managed runtime release layout: - -- the stable loader at `/etc/nginx/nginx.conf` reads virtual-host configs from `/etc/nginx/runtime/current/conf.d/*.conf` -- each reload stages a full config snapshot under `/etc/nginx/runtime/releases/` -- the staged snapshot is validated with `nginx -t -c /.validation-nginx.conf` before activation -- activation swaps the `current` symlink atomically, preserves a `last-known-good` symlink, and rolls back automatically if `nginx -s reload` fails -- each staged release records metadata in `lyttle-nginx-release.json`, including validation output, apply node, phase, and rollback context when relevant - -If your Swarm nodes are not mutually reachable by node hostname, override `CLUSTER_CONTROL_ADDRESS` with a routable internal DNS name or address per node before treating cluster operations as healthy. -

Full local-login/service-account lifecycle APIs were not required for the shipped operating model. | +| `6.2` Cluster topology/control API | Partial | The repo ships status/lease/leader/nodes/operations visibility, but not the full aspirational drain/maintenance/reconcile/lease-transfer surface. | +| `6.3` Desired-state/config rollout API | Partial | Transactional staged rollout exists internally and node config state is visible, but a dedicated draft/commit/diff/rollback API surface is not implemented. | +| `6.4` Proxy management API | Mostly done | CRUD, validation, and upstream test support ship today, though enable/disable lifecycle endpoints are not separate routes. | +| `6.5` Certificate lifecycle API | Mostly done | Listing, challenge inspection, retries, renewals, rollback, upload/import/export, and backup endpoints exist. Cancel/revoke/history/distribution/activate endpoints are not all separate first-class routes. | +| `6.6` Node sync/apply status API | Partial | Node-specific config/certificate views exist under the cluster API, but not the full standalone `/nodes/*` surface. | +| `6.7` Backup/restore/disaster recovery API | Partial | Encrypted backup verify/restore flows exist for certificate material, but not a generic restore-job orchestration API or full DB DR bundle management. | +| `6.8` Observability/audit API | Mostly done | Metrics, audit, logs, and deep health endpoints ship today. Dedicated event-stream and log-search APIs do not. | +| `6.9` Security administration API | Done with one deferred contract | Security posture and key-rotation endpoints exist. Internal-cert rotation remains a placeholder contract until mTLS exists. | +| `7` Security hardening checklist | Mostly done with explicit deferments | Auth, RBAC, at-rest encryption, audit trails, secret redaction, signed backups, and CI scans are in place. mTLS, first-class secret integration, tuned rate controls, and full container hardening remain deferred. | +| `8` Observability and SRE requirements | Mostly done | The repository now exposes most of the requested metrics/runbooks/alerts guidance. External monitoring, alert routing, and environment-specific thresholds remain deployment responsibilities. | +| `9` Data model changes | Done via equivalent persisted models | The schema now includes durable certificate orders/events/artifact versions, cluster leases, cluster operations/ACKs, audit events, ACME challenges, and richer cluster node metadata. | +| `10` Testing strategy required before calling this production-ready | Mostly done | Unit, integration, e2e, and deterministic chaos tests exist and are gated in CI.

The repository also relied on per-endpoint guard annotations, which made it easy to miss new routes and accidentally expose control-plane functionality. - -### Decision - -Adopt an authenticated-by-default API policy for the NestJS control plane: - -1. register the API-key guard globally so admin and internal-control endpoints require authentication unless explicitly marked otherwise -2. keep a small, explicit public allowlist using a `@Public()` decorator -3. limit the current public allowlist to: - - `GET /health` - - `GET /ready` - - `GET /metrics` - - `GET /metrics/json` - - `GET /.well-known/acme-challenge/:token` -4. remove the previous development-mode bypass that made protected endpoints public when `API_KEY` was unset - -### Consequences - -- new endpoints are protected by default, which reduces the chance of future accidental public mutations -- operators must configure `API_KEY` even in local evaluation when they need to access admin endpoints -- public observability and ACME flows remain available, but all other current API surfaces should be treated as admin/control-plane endpoints -- Session 7 and Session 8 can build on this deny-by-default posture when introducing richer identity and RBAC models - ---- - -## ADR-007 — Explicit probe endpoints with dependency-aware readiness - -- Status: accepted -- Session: Session 4 — Fix health, readiness, liveness, and startup semantics -- Date: 2026-05-24 - -### Context - -The previous health model exposed only `/health` and `/ready`, always returned HTTP 200 for readiness, and did not validate the database or recent control-plane convergence. That allowed orchestration layers to keep routing traffic to nodes that had lost PostgreSQL connectivity, had stale config/certificate state, or had not finished startup. - -### Decision - -Adopt explicit probe semantics for the NestJS control plane: - -1. expose `GET /health/live` for liveness -2. expose `GET /health/startup` for startup completion -3. expose `GET /health/ready` for readiness -4. keep `GET /health` and `GET /ready` as temporary compatibility aliases for liveness and readiness respectively -5. make readiness return HTTP 503 when any critical dependency check fails -6. require readiness to validate at least: - - PostgreSQL connectivity - - NGINX master-process health - - a recent successful config apply - - a recent successful certificate sync -7. update the container healthcheck script to inspect both the readiness HTTP status and the JSON body - -### Consequences - -- orchestrators can now distinguish “process alive” from “safe to receive traffic” -- the service stays unready after restart until config apply and certificate sync have completed successfully at least once -- later sessions should persist and broaden health signals beyond the current in-memory freshness tracking, especially for cluster-wide convergence and richer observability - ---- - -## ADR-008 — Fail-fast container supervision and restart-friendly deployment policies - -- Status: accepted -- Session: Session 5 — Fix container and process auto-recovery behavior -- Date: 2026-05-24 - -### Context - -The previous container startup flow tried to recover crashes inside `docker-entrypoint.sh`, but it did so unsafely: - -- failure paths ended with `exit 0`, which could suppress orchestrator restarts -- repeated failures eventually triggered `sleep infinity`, leaving the service permanently wedged -- `nginx` daemonized away from the supervising shell, which made process-state tracking fragile -- the Swarm manifest limited restart attempts to three failures, which was too aggressive for the intended self-healing edge runtime - -### Decision - -Adopt a fail-fast supervision model for the current single-container runtime: - -1. run the NestJS process and the NGINX master as directly supervised child processes -2. start NGINX in foreground mode (`daemon off;`) so the entrypoint can track its actual lifecycle -3. treat any unexpected child-process exit as a container failure and exit non-zero so Docker or Swarm can restart the container -4. reserve exit code `0` for intentional shutdowns initiated by container stop signals -5. remove restart-state bookkeeping, in-container retry suppression, and all `sleep infinity` wedged states -6. configure deployment manifests to prefer continued recovery: - - Compose uses `restart: unless-stopped` - - Swarm uses `restart_policy.condition: any` without a hard `max_attempts` cap - - both manifests allow a grace window for orderly child-process shutdown - -### Consequences - -- Node or NGINX crashes now translate into observable container failures instead of hidden partial outages -- graceful container stops still terminate both supervised processes cleanly without turning normal shutdown into a failure -- the current architecture still relies on a shell-based two-process container, so later sessions may still choose to split the control plane from the edge runtime or adopt a dedicated supervisor - ---- - -## ADR-009 — Explicit advertised control-plane endpoints for cluster communication - -- Status: accepted -- Session: Session 6 — Fix inter-node addressing and Swarm communication model -- Date: 2026-05-24 - -### Context - -The production-readiness assessment identified two related cluster-communication flaws: - -- nodes tried to discover their identity through third-party public-IP services -- inter-node requests assumed `process.env.PORT` matched the peer-facing reachable port in Swarm - -That made peer communication fragile, leaked topology information to public services, and broke the distinction between the container's internal listen port and the port other nodes must actually call. - -### Decision - -Adopt an explicit advertised control-plane endpoint model: - -1. each node advertises a routable control-plane address using `CLUSTER_CONTROL_ADDRESS` or `CLUSTER_CONTROL_URL` -2. each node advertises a peer-facing control-plane port using `CLUSTER_CONTROL_PORT` -3. `PORT` remains the local NestJS listen port and must not be reused implicitly for peer URL construction -4. cluster registration stores the advertised control-plane endpoint in node metadata -5. inter-node reload and certificate-sync broadcasts build their URLs from the registered endpoint, not from public-IP discovery or hard-coded port assumptions -6. loopback or otherwise non-routable advertised endpoints are rejected for peer use in production-mode registration - -### Consequences - -- Swarm and other clustered deployments must now provide explicit control-plane addressing configuration -- operators can inspect the registered peer endpoint for each node through cluster metadata instead of inferring behavior from logs or container internals -- inter-node communication remains HTTP + API-key authenticated for now; Session 7, Session 8, and later security work still need to introduce stronger node identity and transport security - ---- - -## ADR-010 — Identity-aware auth foundation with bearer-token support and legacy API-key compatibility - -- Status: accepted -- Session: Session 7 — Introduce a real auth foundation -- Date: 2026-05-24 - -### Context - -The production-readiness assessment identified the current shared API-key model as too weak for real production administration because it lacked request identity, richer claim semantics, and a credible bridge toward RBAC, audit logging, and stronger internal node authentication. - -Session 3 already moved the API surface to authenticated-by-default, but the code still treated auth as a yes/no API-key check rather than an actor model. - -### Decision - -Adopt an identity-aware authentication foundation with the following properties: - -1. keep the API authenticated by default using the existing global guard posture -2. allow that guard to resolve either: - - legacy API keys (`X-API-Key` or `Authorization: ApiKey ...`) - - JWT bearer tokens (`Authorization: Bearer ...`) -3. attach a structured identity object to each authenticated request, including: - - subject - - actor type (`admin` or `internal-node`) - - auth method - - roles - - scopes - - issuer/audience metadata -4. support short-lived locally issued HS256 bearer tokens via `AUTH_JWT_SECRET` -5. support verification of externally issued bearer tokens through standard issuer/audience claims and optional `AUTH_JWT_PUBLIC_KEY` for RS256 verification -6. preserve temporary legacy API-key compatibility and allow API-key-authenticated clients to exchange for a bearer token via `POST /auth/token` -7. introduce identity inspection endpoints (`GET /auth/me`, enriched `GET /auth/status`, and richer `GET /auth/info`) so operators and future tests can observe the resolved actor context - -### Consequences - -- the codebase now has a real request identity object that later sessions can use for RBAC decisions, audit logging, and internal-node policy separation -- operators can begin migrating clients from raw API keys to short-lived bearer tokens without breaking existing integrations immediately -- bearer-token support is intentionally a foundation, not a full security model: Session 8 still needs RBAC, Session 9 still needs audit logging, and later sessions still need stronger internal transport security such as mTLS - ---- - -## ADR-011 — Explicit RBAC policies with a global authorization guard - -- Status: accepted -- Session: Session 8 — Add RBAC and authorization policies -- Date: 2026-05-24 - -### Context - -Session 7 introduced stable request identity, but the API still treated most authenticated actors equivalently. The production-readiness assessment explicitly called for RBAC roles such as `viewer`, `operator`, `security-admin`, `platform-admin`, and `internal-node`, plus an explicit permission matrix for all endpoints. - -Without a second authorization layer, any authenticated caller with a valid credential could still reach sensitive backup, cluster-maintenance, certificate, and TLS-hardening routes. - -### Decision - -Adopt an explicit RBAC model enforced by a global authorization guard: - -1. keep the existing authenticated-by-default posture from Session 3 and identity resolution from Session 7 -2. add a second global guard that evaluates authorization metadata on every non-public route -3. require protected routes to declare an explicit authorization policy; missing policy metadata is treated as a configuration error and denied -4. define the initial RBAC catalog as: - - `viewer` - - `operator` - - `security-admin` - - `platform-admin` - - `internal-node` -5. adopt the following initial hierarchy: - - `platform-admin` implies `security-admin`, `operator`, and `viewer` - - `security-admin` implies `viewer` - - `operator` implies `viewer` - - `internal-node` remains separate from admin roles -6. map the current API surface explicitly, including: - - read-only inspection endpoints → `viewer` - - runtime operational actions such as reload and renew → `operator` - - certificate/key, backup, export/import, and TLS hardening actions → `security-admin` - - cluster leader-management and break-glass maintenance endpoints → `platform-admin` - - internal certificate sync → `internal-node` or `platform-admin` for operator fallback during migration -7. preserve temporary legacy API-key compatibility by continuing to map configured API keys to default admin roles from env configuration - -### Consequences - -- the current endpoint permission matrix is now explicit in code, enforceable at runtime, and regression-tested -- later sessions can add audit logging, service accounts, and finer-grained operational APIs without first reworking the basic authorization model again -- legacy API keys remain a compatibility bridge rather than a destination state; future security work should continue pushing operators toward short-lived bearer identities and narrower role assignment - ---- - -## ADR-012 — Durable audit events for privileged and mutating operations - -- Status: accepted -- Session: Session 9 — Add audit logging for privileged and mutating operations -- Date: 2026-05-24 - -### Context - -Sessions 7 and 8 introduced stable request identity and explicit RBAC, but the control plane still lacked a durable record of who attempted sensitive operations, what they targeted, whether they succeeded, and how to correlate those actions across logs and client-visible failures. - -The production-readiness assessment explicitly called for audit logging of privileged and mutating operations, including failed privileged attempts. - -### Decision - -Adopt a durable audit-event model with request correlation for the current NestJS control plane: - -1. persist audit records in a new Prisma-backed `AuditEvent` table -2. record at least: - - actor identity metadata when available - - action name - - target identifier or label when available - - outcome (`success`, `failure`, or `denied`) - - request method/path and HTTP status - - correlation ID and timestamp -3. generate or propagate a correlation ID for audited requests and return it via `X-Correlation-Id` -4. audit all protected mutating routes by default through a global interceptor -5. allow explicit `@Audit(...)` metadata on routes that need stable action names or auditing despite using non-mutating HTTP verbs -6. record denied attempts directly from the authentication and authorization guards so failed privileged requests are not lost before controller execution -7. expose a minimal privileged audit-review endpoint at `GET /audit` - -### Consequences - -- successful writes, controller/service failures, and denied privileged attempts are now durably attributable even before the later structured-logging work lands -- route authors can opt into clearer action naming and target extraction without reworking the global audit pipeline -- audit storage currently shares the main application database, so later sessions should still harden retention, redaction, export controls, and long-term operational reporting - ---- - -## ADR-013 — Lease-based leader coordination with generation fencing tokens - -- Status: accepted -- Session: Session 10 — Add lease-based coordination primitives -- Date: 2026-05-24 - -### Context - -The previous cluster leader model relied on PostgreSQL advisory locks plus `ClusterNode.isLeader` booleans. That left leader intent split across transient session state and durable database state, made recovery paths advisory-lock-specific, and provided no monotonic fencing token that later cluster-wide operations could use to reject stale leaders. - -The production-readiness assessment called for a durable lease record with expiration and generation semantics. - -### Decision - -Adopt a database-backed lease primitive for leader coordination: - -1. add a new Prisma-backed `ClusterLease` table with a unique `leaseName` -2. store the current owner, acquisition/renewal timestamps, TTL, and expiry in that table -3. maintain a monotonically increasing `generation` value that acts as the leader fencing token -4. preserve the generation when a lease is released so the next owner observes a higher fencing token -5. make the leader-acquisition path in `DistributedLockService` use the durable lease primitive with automatic renewal -6. expose lease state through the cluster API so operators can inspect the active owner and fencing token - -### Consequences - -- leader identity is now durably visible in the database instead of existing only in a PostgreSQL session lock -- future cluster-wide writes can carry the leader generation and reject stale actors using the fencing token -- the codebase remains in a transitional hybrid state until Session 11 finishes moving heartbeat and leader reconciliation fully onto the lease model - ---- - -## ADR-014 — Lease-backed heartbeat and leader reconciliation - -- Status: accepted -- Session: Session 11 — Move heartbeat and leader flows onto leases -- Date: 2026-05-24 - -### Context - -Session 10 introduced durable `ClusterLease` records and generation-based fencing tokens, but the heartbeat service still treated `ClusterNode.isLeader` as an operational source of truth. That left split-brain recovery logic dependent on stale DB flags and heartbeat recency rather than the current leader lease. - -### Decision - -Adopt the leader lease as the authoritative source of truth for cluster leadership: - -1. derive leader reads, cluster stats, and node leader annotations from the active `cluster:leader` lease -2. treat `ClusterNode.isLeader` as a denormalized observability field only, reconciled from the lease rather than used for leader election -3. when the lease owner is missing or stale, clear denormalized leader flags and wait for lease expiry instead of force-electing a replacement from heartbeat recency -4. simplify admin repair flows so “enforce leader” means reconciling DB flags to the active lease, not choosing a winner from multiple DB leaders - -### Consequences - -- leadership and membership diagnostics now stay aligned with durable lease ownership instead of transient DB flag drift -- stale-node cleanup no longer performs risky split-brain arbitration; it marks nodes stale and lets lease expiry govern failover timing -- operator-facing leader status can explicitly report lease-owner-missing or lease-owner-not-active states, which were previously hidden behind generic “multiple leaders” logic -- later sessions can layer cluster operations and per-node ACKs onto a cleaner lease-backed control-plane model without preserving the old DB-leader election semantics - ---- - -## ADR-015 — Durable cluster operation journal with per-node acknowledgements - -- Status: accepted -- Session: Session 12 — Add cluster operations and per-node ACK tracking -- Date: 2026-05-24 - -### Context - -Sessions 10 and 11 established lease-backed leader coordination, but cluster-wide mutations still returned local-only success. That meant operators could not tell whether a reload or sync had actually converged across the cluster, and later certificate/config rollout work had no durable operation record to build on. - -### Decision - -Represent cluster-wide mutations as durable operations with explicit per-node acknowledgement state: - -1. add new Prisma-backed `ClusterOperation` and `ClusterOperationAck` tables to persist operation intent, status, and per-node outcomes -2. introduce a `ClusterOperationsService` that creates operation records before execution, seeds ACK rows for all targeted nodes, runs local work, and issues authenticated peer calls to collect ACKs -3. change cluster-wide reload requests to return `202 Accepted` with an operation ID instead of a best-effort synchronous broadcast result -4. expose operation inspection endpoints so operators can query current status and per-node ACK details -5. route cluster-triggered certificate sync broadcasts through the same operation journal so later certificate activation work can reuse a consistent contract - -### Consequences - -- cluster-wide mutations now have durable, queryable status instead of collapsing into local-node success responses -- operators can inspect which nodes succeeded or failed for a given operation before later Session 22 API expansion work lands -- future sessions can layer desired-state versions, certificate activation ACK policies, and richer operational metrics onto the shared operation journal instead of inventing separate tracking paths -- operation execution is still initiated in-process on the requesting node, so restart-resume durability and stronger internal transport guarantees remain future work - ---- - -## ADR-016 — Staged NGINX runtime releases with atomic activation and rollback - -- Status: accepted -- Session: Session 13 — Implement staged NGINX config generation and atomic activation -- Date: 2026-05-24 - -### Context - -The previous NGINX reload flow cleared `/etc/nginx` in place, recopied repository assets directly into the live directory, regenerated configs there, and only then ran `nginx -t`. That meant a failed copy, partial write, or invalid generated config could leave a node with a broken or incomplete live NGINX tree before validation had even occurred. - -### Decision - -Adopt a staged runtime-release model for NGINX virtual-host configuration: - -1. keep `/etc/nginx/nginx.conf` as a stable loader that includes `/etc/nginx/runtime/current/conf.d/*.conf` -2. create a full staged release under `/etc/nginx/runtime/releases/` for every reload attempt -3. validate the staged release with a release-specific `nginx -t -c /.validation-nginx.conf` before activation -4. activate a validated release by atomically swapping the `current` symlink to the new release -5. preserve a `last-known-good` symlink and automatically roll back to the prior release if `nginx -s reload` fails after activation -6. record release metadata on disk in `lyttle-nginx-release.json`, including release phase, apply node, validation output, and rollback context when applicable -7. bootstrap a runtime `current` and `last-known-good` release at container startup so the stable loader is usable before the first dynamic reload occurs - -### Consequences - -- invalid generated configs are rejected before they become the active NGINX release -- live config activation no longer depends on destructive in-place mutation of `/etc/nginx` -- operators have a filesystem-local rollback point and release metadata trail even before later sessions add richer config-version APIs or database-backed apply history -- later sessions should build on this model for metrics, operator inspection APIs, certificate artifact activation, and stronger controls around advanced custom NGINX fragments - ---- - -## ADR-017 — Validated allowlisted `nginx_custom_code` fragments - -- Status: accepted -- Session: Session 14 — Restrict or redesign `nginx_custom_code` -- Date: 2026-05-24 +- `npm run audit:prod` -### Context - -Even after Session 13 made NGINX rollout transactional, `ProxyEntry.nginx_custom_code` still flowed straight into generated server blocks as raw text.

Session 17 also made certificate activation ACK-driven, which increased the need for operator-facing APIs that answer “what happened on this node?” without requiring direct database access. - -### Decision - -Adopt an operator-focused cluster inspection surface with the following characteristics: - -1. add `GET /cluster/status` as a single aggregated overview that combines cluster counts, leader/lease health, active-node summaries, and recent operation state -2. extend `GET /cluster/operations` so operators can filter the operation journal by node and operation type while receiving normalized status-summary metadata and stable self-links -3. add node-detail endpoints: - - `GET /cluster/nodes/:nodeId` - - `GET /cluster/nodes/:nodeId/config` - - `GET /cluster/nodes/:nodeId/certificates` -4. treat the durable operation journal as the primary source of per-node convergence history, while enriching the local node view with runtime NGINX release metadata and the current certificate inventory from the shared database -5. keep the new cluster-inspection APIs read-only and RBAC-protected under the existing `viewer` posture so later sessions can layer richer logging, metrics, and desired-state workflows on top without reworking the basic operator contract again - -### Consequences - -- operators can now answer cluster-status and node-convergence questions through authenticated API calls instead of correlating multiple low-level routes or inspecting the database directly -- async operation responses now expose a more uniform contract across accepted, listed, and detailed operation views, which gives later admin APIs a stable status-summary shape to reuse -- remote-node config/certificate detail is still limited to the current ACK payload plus cluster metadata; later sessions should expand that with structured logs, metrics, and desired/applied-state version tracking rather than bypassing the operation journal - ---- - -## ADR-026 — Security administration APIs expose posture review, manual rotation bridges, and a future internal-cert rotation contract - -- Status: accepted -- Session: Session 23 — Add security administration APIs - Date: 2026-05-28 -### Context - -After Sessions 7-20, the project had stronger auth, RBAC, audit logging, encrypted private-key storage, and hardened backup artifacts, but operators still lacked a dedicated security-administration API surface. Important maintenance tasks such as checking secret posture, reviewing effective access, rotating API keys safely, and re-encrypting stored private keys after a master-key version bump were still implicit or dependent on direct environment/config edits with little in-app guidance. - -The roadmap for Session 23 also called for break-glass documentation and an internal-certificate rotation hook for future mTLS work. - ### Decision -Adopt a dedicated `/security` administration surface with the following rules: - -1. add posture-review endpoints under `security-admin` RBAC: - - `GET /security/status` - - `GET /security/policy` - - `GET /security/secrets/health` - - `GET /security/access-review` -2. keep higher-risk maintenance actions explicit and auditable: - - `POST /security/rotate/api-key` → `platform-admin` - - `POST /security/rotate/private-key-encryption` → `security-admin` - - `POST /security/rotate/internal-certs` → `platform-admin` -3. treat API-key rotation as a **manual overlap + redeploy** workflow for now; the endpoint validates the proposed key, reports safe fingerprints/IDs, and can optionally mint a short-lived bearer-token bridge when `AUTH_JWT_SECRET` is configured -4. use the existing Session 19 private-key migration logic as the operator-facing rotation hook for certificate-key re-encryption after `PRIVATE_KEY_ENCRYPTION_KEY_VERSION` changes -5. expose the internal certificate rotation endpoint immediately as a stable contract, but return a documented “not configured” response until node-to-node mTLS and internal PKI actually exist -6. add an explicit break-glass runbook so decrypted certificate export and legacy API-key overlap procedures are documented rather than tribal knowledge +- leader ownership is derived from persisted lease state +- cluster-wide mutations are recorded as operations with per-node acknowledgements +- operator visibility is exposed through cluster status, lease, operations, and node-detail APIs ### Consequences -- operators can now review secret/configuration posture and their own effective security capabilities without direct database access or environment inspection -- API-key rotation becomes safer even though it is still deployment-driven, because the platform can validate candidates, report current key fingerprints, and provide a bearer-token migration bridge without exposing raw key material -- private-key master-key rotation now has an authenticated in-app trigger for the actual re-encryption pass, reducing the chance that operators bump `PRIVATE_KEY_ENCRYPTION_KEY_VERSION` but forget to migrate stored rows -- the `/security/rotate/internal-certs` endpoint makes the current inter-node mTLS gap explicit while preserving a stable API contract for the future PKI workflow -- break-glass actions remain narrow, highly privileged, and auditable instead of being treated as undocumented side paths +- cluster behavior is observable beyond local-node success responses +- split-brain mitigation depends on lease ownership rather than stale DB leader flags +- inter-node transport hardening remains a separate deferred concern --- -## ADR-027 — Structured stdout operational logging with request-scoped context and redaction +## ADR-007 — NGINX rollout is staged, validated, and rollback-aware - Status: accepted -- Session: Session 24 — Replace ad hoc logging with structured operational and audit logging - Date: 2026-05-28 -### Context - -Session 9 added durable audit persistence, but the operational logging path was still ad hoc: synchronous local file writes, duplicated stdout/stderr writes, inconsistent plain-text messages, and no common request/actor/operation context on runtime logs. That made centralized collection harder and increased the chance of leaking sensitive material in logs. - ### Decision -Adopt the following operational logging model for the current monolith: - -1. treat stdout/stderr as the primary operational log sink and emit machine-parseable JSON lines there -2. keep a small in-memory ring buffer only for the authenticated `GET /logs` review endpoint; do not treat local files as the primary store anymore -3. propagate per-request context through async execution so operational logs can include: - - correlation/request ID - - request method/path/IP - - actor identity and roles when available - - node ID - - cluster operation ID when a workflow is operating inside a tracked operation -4. keep audit logging as a separate concern backed by the `AuditEvent` table and `GET /audit`, rather than mixing audit records into the operational log stream -5. apply consistent redaction for obviously sensitive values such as API keys, bearer tokens, cookies, master/encryption secrets, and PEM private keys before they are written to logs -6. log request lifecycle completion and exception events through the same structured operational logger so HTTP activity is traceable without scraping Nest's default console format +- config generation produces staged releases +- staged config is validated before activation +- activation swaps runtime pointers atomically +- reload failure triggers rollback to the last-known-good release +- custom NGINX fragments are restricted by allowlisted guardrails ### Consequences -- operators and log shippers can now parse control-plane runtime logs consistently and correlate them with audit events through shared correlation IDs -- request/actor/operation context is attached once in middleware/async context rather than reimplemented piecemeal inside every service -- the `/logs` endpoint now exposes structured entries for the current process only, while durable review of privileged actions remains the responsibility of `GET /audit` -- later sessions can enrich this schema with additional metrics, node-state detail, and external log shipping guidance without reintroducing synchronous file logging or mixed audit/operational concerns +- runtime config rollout is safer than direct in-place mutation +- a dedicated manual rollback API is still deferred +- operator runbooks must document rollback and recovery workflows clearly --- -## ADR-028 — Dependency drilldowns plus state-based Prometheus metrics for leases, operations, orders, and backups +## ADR-008 — Certificate lifecycle state is durable and rollback-aware - Status: accepted -- Session: Session 25 — Expand metrics and alerting - Date: 2026-05-28 -### Context - -After Session 24, operational logs were structured and correlated, but the public metrics surface was still shallow: mostly certificate and proxy counts. Operators still lacked first-class metrics for leader leases, cluster operation backlog/failures, certificate-order staleness, backup freshness, and richer dependency drilldowns beyond the binary readiness response. - ### Decision -Adopt the following observability model for the current monolith: - -1. keep `GET /metrics` public and extend it with state-based Prometheus gauges for: - - dependency health and DB latency - - config-apply and certificate-sync freshness - - leader lease presence, expiry window, and generation - - cluster operations by status/type plus recent failure windows and ACK rollups - - certificate orders by lifecycle state plus stale/retry counts - - encrypted backup inventory and freshness - - per-section metrics collection success/failure so partial scrape issues are visible -2. keep `GET /metrics/json` as the dashboard/debug-friendly JSON mirror of the same data, including per-section `collection.errors` -3. add `GET /health/dependencies` for direct dependency drilldowns and `GET /health/deep` for combined liveness/startup/readiness/dependency inspection -4. drive alert recommendations primarily from *current state* and *recent failure windows* rather than all-time counters, so Prometheus alerts can debounce and clear cleanly -5. document recommended alert rules and dashboard panels in operator docs instead of embedding policy directly in the app runtime +- certificate orders are durable +- artifact versions are tracked explicitly +- artifact activation is coordinated across the cluster with ACKs +- rollback to a prior artifact version is supported ### Consequences -- operators can now distinguish a node that is merely “up” from one that is healthy, converged, and backed by fresh config/certificate/backup state -- dashboards and alerts can reason about lease expiry, stuck operations, stale certificate workflows, and backup freshness without shelling into the node -- metrics scrapes can degrade gracefully when one section fails, while still exposing section-level collection errors to Prometheus and the JSON API -- later sessions can build historical SLOs, chaos validation, and CI release gates on top of a broader but still stable observability contract +- certificate workflows survive retries and partial failures more cleanly than file-only flows +- cluster activation state is inspectable +- broader disaster recovery remains partly external to the repository --- -## ADR-029 — Classified Node.js test harness with shared preload and baseline coverage pillars +## ADR-009 — Built-in ACME support is limited to shared HTTP-01 for non-wildcard issuance - Status: accepted -- Session: Session 26 — Add automated test harness and baseline coverage - Date: 2026-05-28 -### Context - -The repository had accumulated many focused regression tests across Sessions 3-25, but they were still treated as one undifferentiated `npm run test` command. The implementation plan for Session 26 requires an explicit unit/integration/e2e harness, stable test commands, and clear baseline coverage for auth, health, leases, config rollout, and certificate-order transitions. - ### Decision -Adopt the built-in Node.js test runner as the repository-standard harness, with an explicit suite manifest and shared preload layer: - -1. keep the current Node.js + `ts-node/register/transpile-only` test stack instead of introducing a second framework, so the repo continues to run tests directly against the existing CommonJS/TypeScript mix -2. add a shared preload entrypoint that loads `reflect-metadata` and defaults `NODE_ENV=test` for all test invocations -3. classify every `test/**/*.test.js` file into one of three named suites: - - `unit` - - `integration` - - `e2e` -4. make suite classification explicit in a checked-in harness config and fail the runner if any discovered test file is unclassified or any configured file is missing -5. expose first-class commands for `npm run test`, `npm run test:unit`, `npm run test:integration`, `npm run test:e2e`, `npm run test:coverage`, and `npm run test:list` -6. treat the following as the Session 26 baseline coverage pillars: - - auth - - health - - leases - - config generation - - certificate-order transitions -7. update `npm run verify` so automated tests are now part of the default repository verification contract rather than an optional extra step +The built-in ACME flow supports shared HTTP-01 challenge handling only. Wildcard and DNS-01 issuance are intentionally not part of the shipped design. ### Consequences -- contributors and future CI jobs can target the right test depth quickly instead of running an opaque monolithic suite every time -- new test files now require intentional classification, which reduces drift between “tests that exist” and “tests the harness actually runs” -- the repository gains a stable entrypoint for later Session 27 chaos/fault suites and Session 28 CI gating without replacing the existing Node-native runner -- coverage reporting is now available from the same harness, while stricter thresholds and release gates remain future work for Session 28 +- operators needing wildcard issuance must use another strategy such as import/upload workflows +- ACME behavior stays aligned with the current cluster-safe implementation +- docs and validation messages must state this limit explicitly --- -## ADR-030 — Dedicated deterministic chaos suite for recovery and fault-injection validation +## ADR-010 — Private keys and backup artifacts are protected at rest - Status: accepted -- Session: Session 27 — Add chaos and fault-injection validation - Date: 2026-05-28 -### Context - -By the end of Session 26, the repository had strong focused regressions for auth, health semantics, leases, cluster operations, rollback-safe config rollout, certificate orders, and backup/security behavior. What it still lacked was a single reproducible way to prove the critical failure-mode claims called out in the production-readiness assessment and the Session 27 roadmap scope: database outages, leader crashes, NGINX crashes, bad config activation, node communication failure, and partial certificate activation failure. - -Running those drills only as ad hoc manual steps would make them hard to repeat locally and difficult to gate in CI later. Fully externalized chaos infrastructure is also out of scope for the current in-repo test harness. - ### Decision -Add a dedicated `chaos` suite to the Node.js repository harness and implement Session 27 failure drills as deterministic, in-process fault-injection scenarios: - -1. keep using the existing Node.js test runner and shared preload path from Session 26 instead of introducing a second chaos framework -2. expose `npm run test:chaos` as the focused entrypoint for recovery/failure-mode validation -3. include the `chaos` suite in `npm run test` by way of the `all` harness classification so recovery proof is part of the default repository regression contract -4. model failure scenarios with deterministic shims and mocks close to the affected code paths, including: - - PostgreSQL readiness failure - - stale leader crash with lease-expiry recovery - - supervised NGINX master crash in `docker-entrypoint.sh` - - staged-config activation rollback after reload failure - - inter-node communication timeout/error handling in cluster operations - - partial certificate activation failure that preserves the prior active artifact -5. treat the Session 27 chaos suite as a baseline recovery-evidence pillar that complements, rather than replaces, later environment-level Swarm or infrastructure chaos drills +- stored TLS private keys use application-layer envelope encryption metadata +- backup artifacts are encrypted and signed +- raw PEM export remains a break-glass path only ### Consequences -- the repository now has a repeatable, code-reviewed proof path for the core failure scenarios that previously relied on design intent or isolated unit/integration tests -- contributors can run only the failure drills when iterating on recovery-sensitive code without re-running every other suite first -- Session 28 can wire `npm run test:chaos` into CI as an explicit release gate alongside the existing suite families -- later operator runbooks and final readiness validation can reference the same deterministic scenarios as the documented minimum recovery baseline +- production secret handling is stronger than plaintext storage +- external KMS, Vault, or HSM integration remains deferred +- restore guidance must emphasize encrypted backup workflows over raw export --- -## ADR-031 — Multi-job GitHub Actions release gates with coverage thresholds and publish-after-success image delivery +## ADR-011 — Operator visibility relies on structured logs, audit events, health drilldowns, and metrics - Status: accepted -- Session: Session 28 — Upgrade CI/CD and release gating - Date: 2026-05-28 -### Context - -Before Session 28, the repository's GitHub Actions workflow only built and pushed a container image. It did not verify lint, type safety, automated tests, dependency vulnerabilities, or container-image vulnerabilities before publication. - -That meant broken or insecure revisions could still produce a published image even after Sessions 26 and 27 had already created a meaningful automated regression and fault-injection baseline. - ### Decision -Adopt a gated GitHub Actions release workflow with explicit jobs for the repository's current quality and security checks: - -1. run separate CI jobs for: - - semantic lint (`npm run lint:ci`) - - typecheck (`npm run prisma:generate && npm run typecheck`) - - full automated tests with enforced coverage thresholds (`npm run test:coverage:ci`) - - build (`npm run prisma:generate && npm run build`) - - production dependency audit (`npm run audit:prod`) - - container vulnerability scan (Trivy against the built Docker image) -2. publish the GHCR image only on pushes to `main`, and only after all of the jobs above succeed -3. enforce the current minimum repository coverage thresholds through a dedicated Node.js helper instead of relying on manual review of coverage output: - - line coverage: 70% - - branch coverage: 67% - - function coverage: 76% -4. keep the existing local `npm run lint` command strict, but introduce `npm run lint:ci` that disables only the `prettier/prettier` rule until the repository's existing formatting debt is cleaned up in a separate change -5. add targeted npm overrides for the currently known production-audit transitive dependencies so the dependency gate can pass without waiting for a broader upstream release cadence +The primary observability surfaces are: -### Consequences - -- image publication now depends on the actual verification state of the repository rather than only on Docker build success -- pull requests and main-branch pushes exercise the same core release gates operators expect before publication -- the repository now has an explicit coverage floor suitable for CI enforcement, building directly on the Session 26 and Session 27 harness work -- CI remains honest about the current formatting situation by separating semantic lint failures from repository-wide Prettier cleanup instead of silently dropping lint enforcement entirely -- branch protections and required status checks should be enabled in GitHub settings so the workflow policy also becomes a merge policy - ---- - -## ADR-032 — Operator-facing docs describe the shipped architecture, current limits, and concrete recovery procedures - -- Status: accepted -- Session: Session 29 — Reconcile README, architecture docs, and runbooks with reality -- Date: 2026-05-28 - -### Context - -By the end of Session 28, the codebase had materially changed from the original assessment baseline: leases, ACK-backed operations, staged NGINX activation, durable certificate orders, encrypted backups, structured logs, richer metrics, test harnesses, and CI release gates all existed. The top-level documentation had grown large and uneven, mixing accurate shipped behavior with stale feature-marketing language and missing operational procedures. - -Session 29 specifically requires the docs to stop overstating readiness and to give operators practical runbooks for high-risk workflows. - -### Decision - -Adopt the following documentation posture for operator-facing materials: - -1. keep `README.md` concise and reality-based, focusing on: - - current implementation capabilities - - explicit deployment expectations - - known architectural limits that still matter operationally - - links to the canonical planning/status docs and runbooks -2. add a dedicated current-state architecture document that explains the shipped runtime shape, trust boundaries, major workflows, and unresolved limits without forcing operators to reconstruct that from ADR history alone -3. maintain first-class runbooks for the highest-risk operational scenarios currently supported by the repo: - - leader failure - - NGINX config rollback - - encrypted backup restore - - certificate issuance failure - - credential rotation -4. document current gaps explicitly instead of papering over them, including: - - Session 30 final validation still pending - - internal node transport still using authenticated HTTP rather than mTLS - - the current combined NestJS + NGINX container model - - the lack of a dedicated manual config-rollback API +- structured operational logs +- persisted audit events +- health, dependency, and deep diagnostics endpoints +- Prometheus and JSON metrics ### Consequences -- operators now have a practical starting point for day-2 operations without relying on roadmap prose or code archaeology -- the README is less likely to drift into feature-marketing claims that exceed the actual validated implementation state -- future sessions should update the dedicated architecture overview and affected runbooks whenever they materially change runtime behavior or recovery procedures -- Session 30 can build its final go-live checklist from a documentation set that already distinguishes shipped behavior from remaining validation work +- incident response should start from documented operator APIs rather than direct database inspection where possible +- log redaction and audit persistence remain part of the default operational model +- external monitoring and alert routing are still environment responsibilities --- -## ADR-033 — Final readiness sign-off uses an explicit checklist plus deferment register instead of silently implying parity with the ideal target architecture +## ADR-012 — Tests are organized by suite depth and are part of both CI and Docker build verification - Status: accepted -- Session: Session 30 — Final production-readiness validation pass - Date: 2026-05-28 -### Context - -By Session 30, the repository had completed the planned implementation work across endpoint protection, health semantics, recovery behavior, cluster leases and ACKs, staged NGINX activation, certificate-order durability, encrypted backups, operational APIs, observability, tests, CI gates, and operator documentation. - -At the same time, several original assessment recommendations still remained intentionally unimplemented or only partially implemented, most notably: - -- internal node transport still uses authenticated HTTP rather than mTLS -- the current runtime keeps NestJS and NGINX in the same container -- secret ingestion is still environment-variable driven rather than first-class secret-provider integration -- rate limiting and some Docker runtime hardening expectations remain baseline rather than fully production-tuned -- several assessment sections describe a broader ideal API and target architecture than the current shipped scope - -Declaring the project simply “production-ready” without preserving those boundaries would repeat the documentation overstatement problem Session 29 was created to fix. - ### Decision -Use the following final-readiness posture: - -1. publish a `FINAL_PRODUCTION_CHECKLIST.md` that: - - reconciles every numbered assessment section - - records the verification evidence used for Session 30 - - defines the manual go-live checks operators must complete outside the repository -2. publish a `PRODUCTION_DEFERMENT_REGISTER.md` that captures each accepted residual gap with: - - assessment linkage - - current compensating controls - - impact if left unchanged - - recommended follow-up direction -3. describe the repository as ready only for the **documented current operating model**, not as automatic proof that the ideal target architecture from the assessment has been reached in full -4. require future production claims to reference both the checklist and deferment register together +- tests are classified into `unit`, `integration`, `e2e`, and `chaos` +- the harness fails if discovered tests are unclassified or missing +- CI uses the coverage-gated full suite +- the Docker builder stage runs the same verification contract before producing the runtime image ### Consequences -- Session 30 closes the roadmap without hiding residual risk -- operators get a concrete yes/no rollout checklist instead of scattered caveats across README text and ADR history -- accepted deferments such as internal mTLS, stronger runtime hardening, secret-provider integration, and richer operational APIs remain visible and traceable -- future work can reduce risk incrementally by retiring deferments one-by-one rather than reopening the entire readiness question from scratch -

See deferment `D-006`. | -| `2.4` Leader election too weak | Done | Sessions 10-12, 22, 25, and 27 moved the control plane to lease-backed leadership with generation/fencing metadata, operation journals, per-node ACKs, and failure validation. | -| `2.5` Health, metrics, and alerting incomplete | Mostly done | Sessions 4, 25, 27, and 29 added deep health probes, dependency drilldowns, expanded metrics, alert-rule guidance, and runbooks. External Prometheus/Alertmanager deployment is still an environment responsibility. | -| `2.6` Rate limiting not production-tuned | Deferred | The repository still uses baseline global throttling. Upstream WAF/ingress controls and richer policy tuning remain follow-up work. See deferment `D-005`. | -| `2.7` Logging not production-grade | Done | Session 24 replaced ad hoc logging with structured JSON operational logs, request correlation, actor context, and secret redaction while preserving a separate audit trail. | -| `3.1` CI/CD did not validate production claims | Mostly done | Session 28 added lint/typecheck/test/build/audit/container-scan release gates and publish-after-gates behavior. SBOM generation and GitHub branch-protection enforcement remain external follow-up items. | -| `3.2` No automated tests | Done | Sessions 26 and 27 introduced classified unit/integration/e2e/chaos suites plus coverage gating. | -| `3.3` Documentation inconsistent with reality | Done | Sessions 29 and 30 aligned the README, architecture docs, runbooks, checklist, and deferment register with shipped behavior and remaining boundaries. | -| `3.4` Docker packaging security/reproducibility issues | Partially done | The image is now multi-stage and base-image-pinned, but non-root runtime, log-file permissions, secret ingestion, and capability/read-only-fs hardening are not fully complete. See deferments `D-003` and `D-007`. | -| `3.5` Single-instance compose invalid for production use | Done for documented evaluation scope | `docker-compose.yml` and `docker-compose.swarm.yml` now present separate, explicit deployment examples. Single-node Compose remains evaluation-focused rather than the preferred hardened rollout path. | -| `3.6` Default NGINX template issues | Done | Default asset/template paths were corrected and later exercised by the staged-rollout tests. | -| `4.1` Known dependency vulnerabilities | Mostly done | Session 2 patched the direct dependency issues, and Session 28 added automated production dependency auditing in CI. SBOM generation remains deferred. | - -### 2. Target-architecture, API, and operational recommendation sections - -| Assessment section | Disposition | Evidence / current position | -| --- | --- | --- | -| `5.1` Recommended target architecture | Partial / accepted alternative | The repository still runs a combined NestJS + NGINX container. This is explicitly documented rather than implied away. | -| `5.2` Cluster-safe certificate design | Done for current scope | The shipped design uses leader-coordinated shared HTTP-01, durable order state, encrypted artifact storage, and ACK-backed activation for non-wildcard certificates. | -| `5.3` Stronger coordination model | Done | Lease records, generation counters, operation journals, and ACKs replaced the earlier advisory-lock-only posture. | -| `6.1` Auth/authz API | Partial | The current API exposes `GET /auth/status`, `GET /auth/info`, `GET /auth/me`, and `POST /auth/token`. Full local-login/service-account lifecycle APIs were not required for the shipped operating model. | -| `6.2` Cluster topology/control API | Partial | The repo ships status/lease/leader/nodes/operations visibility, but not the full aspirational drain/maintenance/reconcile/lease-transfer surface. | -| `6.3` Desired-state/config rollout API | Partial | Transactional staged rollout exists internally and node config state is visible, but a dedicated draft/commit/diff/rollback API surface is not implemented. | -| `6.4` Proxy management API | Mostly done | CRUD, validation, and upstream test support ship today, though enable/disable lifecycle endpoints are not separate routes. | -| `6.5` Certificate lifecycle API | Mostly done | Listing, challenge inspection, retries, renewals, rollback, upload/import/export, and backup endpoints exist. Cancel/revoke/history/distribution/activate endpoints are not all separate first-class routes. | -| `6.6` Node sync/apply status API | Partial | Node-specific config/certificate views exist under the cluster API, but not the full standalone `/nodes/*` surface. | -| `6.7` Backup/restore/disaster recovery API | Partial | Encrypted backup verify/restore flows exist for certificate material, but not a generic restore-job orchestration API or full DB DR bundle management. | -| `6.8` Observability/audit API | Mostly done | Metrics, audit, logs, and deep health endpoints ship today. Dedicated event-stream and log-search APIs do not. | -| `6.9` Security administration API | Done with one deferred contract | Security posture and key-rotation endpoints exist. Internal-cert rotation remains a placeholder contract until mTLS exists. | -| `7` Security hardening checklist | Mostly done with explicit deferments | Auth, RBAC, at-rest encryption, audit trails, secret redaction, signed backups, and CI scans are in place. mTLS, first-class secret integration, tuned rate controls, and full container hardening remain deferred. | -| `8` Observability and SRE requirements | Mostly done | The repository now exposes most of the requested metrics/runbooks/alerts guidance. External monitoring, alert routing, and environment-specific thresholds remain deployment responsibilities. | -| `9` Data model changes | Done via equivalent persisted models | The schema now includes durable certificate orders/events/artifact versions, cluster leases, cluster operations/ACKs, audit events, ACME challenges, and richer cluster node metadata. | -| `10` Testing strategy required before calling this production-ready | Mostly done | Unit, integration, e2e, and deterministic chaos tests exist and are gated in CI.

- Session 28 — upgrade CI/CD and release gating -- Notes: - - upgraded the direct dependency versions called out in the assessment (`@nestjs/core`-aligned Nest packages and `nodemailer`) - - follow-up maintenance on 2026-05-24 refreshed the full npm package set to the latest available versions, regenerated `package-lock.json`, and pinned the repo toolchain to Node `24.16.0` and npm `11.15.0` - - tightened `.gitignore` so live env files, generated key material, and backup artifacts stay out of git while keeping `.env.example` tracked - - rewrote `.env.example` to use safe placeholders and explicit runtime-injection guidance - - documented Docker Swarm secrets and external secret-manager expectations in `README.md` - ---- - -## Phase 1 — Emergency hardening and correctness fixes - -## Session 3 — Lock down public mutating endpoints -

- `src/health/health.controller.ts` - - `src/metrics/metrics.controller.ts` - - `test/session3/auth-lockdown.test.js` -- Tests added/updated: - - added `test/session3/auth-lockdown.test.js` to prove unauthenticated writes are rejected and explicit public probe endpoints remain reachable - - wired `npm run test` to execute the Session 3 regression checks with Node's built-in test runner - - verified the focused access-control test suite passes locally -- Risks: - - authentication is still API-key based only; Session 7 and Session 8 remain responsible for real identity and RBAC - - internal node-to-node traffic still shares the same auth mechanism and is not yet mTLS-protected - - health/readiness semantics are still shallow until Session 4 lands -- Follow-up sessions: - - Session 4 — fix health, readiness, liveness, and startup semantics - - Session 7 — introduce a real auth foundation - - Session 8 — add RBAC and authorization policies - - Session 26 — expand automated test coverage beyond the current focused regression set -- Notes: - - admin and internal-control endpoints are now authenticated by default through a global guard - - the explicit public allowlist is currently limited to health probes, metrics, and the ACME challenge endpoint - - removed the previous development-mode auth bypass so write endpoints no longer become public when `API_KEY` is unset - -## Session 4 — Fix health, readiness, liveness, and startup semantics - -- Status: done -- Objective: make health signaling reliable for orchestration and recovery -- Files touched: -

- added `test/session4/health-semantics.test.js` to verify explicit liveness/startup/readiness routes and their HTTP status semantics - - validated the focused Session 4 test suite locally with the repository test runner -- Risks: - - readiness still relies on in-memory timestamps for config apply and certificate sync, so state is reset on process restart until the first successful post-boot operations complete - - cluster communication health and deeper dependency reporting remain future work for Session 6 and Session 25 -- Follow-up sessions: - - Session 5 — fix container and process auto-recovery behavior - - Session 6 — fix inter-node addressing and Swarm communication model - - Session 25 — expand metrics and alerting - - Session 27 — add chaos and fault-injection validation -- Notes: - - added explicit `GET /health/live`, `GET /health/startup`, and `GET /health/ready` endpoints while keeping `/health` and `/ready` as compatibility aliases - - readiness now returns non-200 when PostgreSQL, NGINX master health, recent config apply, or recent certificate sync checks fail - - `healthcheck.sh` now inspects both the readiness HTTP status and the JSON body instead of trusting status code alone - -## Session 5 — Fix container and process auto-recovery behavior - -- Status: done -- Objective: ensure process failure leads to correct container recovery -- Files touched: - - `docker-entrypoint.sh` - - `docker-compose.yml` - - `docker-compose.swarm.yml` - - `README.md` - - `IMPLEMENTATION_STATUS.md` - - `ARCHITECTURE_DECISIONS.md` - - `test/session5/entrypoint-recovery.test.js` -- Tests added/updated: - - added `test/session5/entrypoint-recovery.test.js` to verify fail-fast supervision for Node and NGINX crashes, graceful signal handling, and restart-policy regressions in the deployment manifests - - validated the focused Session 5 recovery suite locally with the repository test runner -- Risks: - - Node and NGINX still share a single container, so this remains shell-based supervision rather than a split control-plane/dataplane architecture or a dedicated supervisor - - restart behavior now depends on Docker or Swarm policy after container exit; deeper fault-injection proof remains planned for Session 27 -- Follow-up sessions: - - Session 6 — fix inter-node addressing and Swarm communication model - - Session 13 — implement staged NGINX config generation and atomic activation - - Session 27 — add chaos and fault-injection validation -- Notes: - - removed restart-state tracking, `sleep infinity`, and all failure paths that masked crashes with `exit 0` - - NGINX now runs as a supervised foreground child, and the entrypoint exits non-zero when either supervised process dies unexpectedly - - the single-node Compose manifest now uses a valid port-mapping configuration instead of the previous conflicting host-network example - - the Swarm manifest now favors continued recovery by restarting on any exit without a hard `max_attempts` cap and by allowing a graceful stop window - -## Session 6 — Fix inter-node addressing and Swarm communication model - -- Status: done -- Objective: use explicit internal control-plane addressing instead of fragile discovery assumptions -- Files touched: -

- added `test/session6/inter-node-addressing.test.js` to cover explicit control-plane endpoint parsing, peer URL construction, and manifest/documentation regressions - - verified the focused Session 6 regression suite locally with the repository test runner - - verified type-checking for the edited TypeScript files after migrating peer URL construction away from `process.env.PORT` -- Risks: - - the current peer transport is still plain HTTP with shared API keys; mTLS and per-node identity remain future work - - Swarm hostname reachability is environment-specific, so operators must override `CLUSTER_CONTROL_ADDRESS` where node hostnames are not resolvable or routable on the internal network - - cluster-wide operations are still best-effort broadcasts without durable ACK tracking until Sessions 10-12 -- Follow-up sessions: - - Session 7 — introduce a real auth foundation - - Session 10 — add lease-based coordination primitives - - Session 11 — move heartbeat and leader flows onto leases - - Session 12 — add cluster operations and per-node ACK tracking -- Notes: - - removed all public-IP discovery from `src/utils/network-utils.ts` and replaced it with explicit `CLUSTER_CONTROL_ADDRESS` / `CLUSTER_CONTROL_PORT` or `CLUSTER_CONTROL_URL` registration - - node heartbeats now persist the advertised control-plane endpoint in cluster metadata so operators and peer workflows can inspect what each node registered - - inter-node reload and certificate-sync broadcasts now build URLs from the registered endpoint instead of assuming the peer-facing port matches the local `PORT` - - authenticated peer requests now attach the configured API key to certificate sync broadcasts so the Session 3 lockdown does not silently break cluster propagation - ---- - -## Phase 2 — Security model foundation - -## Session 7 — Introduce a real auth foundation - -- Status: done -- Objective: move from shared API keys toward a real identity model -- Files touched: - - `src/auth/auth.controller.ts` - - `src/auth/auth.service.ts` - - `src/auth/guards/api-key.guard.ts` - - `src/auth/decorators/current-identity.decorator.ts` - - `src/auth/interfaces/authenticated-request.interface.ts` -

- added `test/session7/auth-foundation.test.js` to verify structured request identity, bearer-token auth, legacy API-key token exchange, and expired-token rejection - - validated the focused Session 7 auth suite locally with the repository test runner - - validated TypeScript type-checking for the edited auth files after introducing bearer-token verification and request identity types -- Risks: - - bearer-token support is now in place, but endpoint-level authorization policy remains coarse until Session 8 introduces RBAC - - inter-node traffic can now carry an `internal-node` identity model, but the transport is still plain HTTP and not yet mTLS-protected - - local token issuance currently uses HS256 shared-secret signing; external IdP/JWKS integration remains future work if operators need full OIDC federation -- Follow-up sessions: - - Session 8 — add RBAC and authorization policies - - Session 9 — add audit logging for privileged and mutating operations - - Session 23 — add security administration APIs -- Notes: - - the global auth guard now resolves either legacy API keys or JWT bearer tokens and attaches a structured identity object to `request.auth` - - the identity model distinguishes `admin` and `internal-node` actors and carries roles/scopes so later RBAC and audit work can build on stable request context - - `POST /auth/token` now provides a migration bridge from API-key clients to short-lived bearer tokens when `AUTH_JWT_SECRET` is configured - -## Session 8 — Add RBAC and authorization policies - -- Status: done -- Objective: make endpoint permissions explicit and enforceable -- Files touched: - - `src/auth/auth.module.ts` - - `src/auth/auth.service.ts` -

- `test/session7/auth-foundation.test.js` - - `test/session8/rbac-authorization.test.js` -- Tests added/updated: - - added `test/session8/rbac-authorization.test.js` to verify viewer/operator/security-admin/platform-admin/internal-node authorization behavior and role hierarchy - - updated the Session 3 and Session 7 auth regression harnesses to include the new global authorization guard - - verified `npm test` passes with the full Session 3-8 regression suite after the RBAC changes landed -- Risks: - - RBAC is now explicit for the current route surface, but it still relies on bearer-token/API-key claims rather than centralized user/service-account persistence - - legacy API keys still map to broad admin roles for migration compatibility; Session 23 should narrow rotation and break-glass workflows further - - internal-node traffic now has a distinct authorization path, but transport security remains HTTP until later mTLS work -- Follow-up sessions: - - Session 9 — add audit logging for privileged and mutating operations - - Session 21 — add proxy management API - - Session 22 — add cluster operations and node-status admin APIs - - Session 23 — add security administration APIs -- Notes: - - added a second global guard so protected endpoints must now have an explicit authorization policy in addition to authentication - - defined the initial role catalog and hierarchy: `viewer`, `operator`, `security-admin`, `platform-admin`, and `internal-node` - - mapped the current API surface to explicit role requirements and documented that matrix in `README.md` - - fixed controller registration order so `/certificates/backup` resolves to the intended backup controller instead of being shadowed by `/certificates/:id` - -## Session 9 — Add audit logging for privileged and mutating operations -

- `README.md` - - `ARCHITECTURE_DECISIONS.md` - - `IMPLEMENTATION_STATUS.md` - - `test/session9/audit-logging.test.js` - - `tsconfig.json` -- Tests added/updated: - - added `test/session9/audit-logging.test.js` to verify successful mutating audit events, denied privileged attempts, controller-level failures, and the new audit review endpoint - - re-ran the repository test suite so Sessions 3-9 continue to pass together after the new global interceptor and guard changes - - regenerated the Prisma client after adding the `AuditEvent` model so TypeScript and runtime code resolve the new table correctly -- Risks: - - audit persistence currently shares the primary application database, so a database outage can still block durable audit writes until later resilience work lands - - audit retention, redaction, export controls, and long-term reporting remain future work for Sessions 20, 23, and 24 - - audit payloads intentionally avoid request bodies by default, which reduces secret exposure but means some targets are represented by IDs or labels rather than full change diffs -- Follow-up sessions: - - Session 20 — harden backup, export, import, and restore flows - - Session 23 — add security administration APIs - - Session 24 — replace ad hoc logging with structured operational and audit logging - - Session 28 — upgrade CI/CD and release gating -- Notes: - - added a Prisma-backed `AuditEvent` model and migration for durable audit persistence - - introduced a global audit interceptor plus explicit `@Audit(...)` route metadata so all protected mutating routes are audited by default and privileged GET-style maintenance actions can opt in explicitly - - updated the authentication and authorization guards to record denied attempts before controller execution, closing the gap for failed privileged actions - - added `GET /audit` for security-admin review workflows and propagated per-request `X-Correlation-Id` headers for audited requests - - aligned the repo with Prisma 7 generation and typing requirements so the new audit-event schema can be generated and type-checked cleanly in this workspace - ---- - -## Phase 3 — Cluster coordination redesign - -## Session 10 — Add lease-based coordination primitives - -- Status: done -- Objective: replace advisory-lock-centric leadership with durable leases and fencing tokens -- Files touched: - - `prisma/schema.prisma` -

- `.env.example` - - `README.md` - - `ARCHITECTURE_DECISIONS.md` - - `IMPLEMENTATION_STATUS.md` - - `test/session10/lease-coordination.test.js` -- Tests added/updated: - - added `test/session10/lease-coordination.test.js` to cover the new lease schema/migration, leader-lease acquisition state, fencing-token validation, and the new cluster lease inspection endpoint - - regenerated the Prisma client after adding `ClusterLease` so the new delegate and schema types resolve correctly in TypeScript - - re-ran the repository test suite so Sessions 3-10 continue to pass together after the lease-foundation changes -- Risks: - - the cluster heartbeat service still maintains transitional `ClusterNode.isLeader` reconciliation until Session 11 completes the full lease-backed leader flow - - cluster-wide operations do not yet persist operation IDs or per-node ACKs; Session 12 remains responsible for making lease ownership actionable across async workflows - - inter-node transport is still authenticated HTTP rather than mTLS, so this session improves coordination correctness but not network trust boundaries -- Follow-up sessions: - - Session 11 — move heartbeat and leader flows onto leases - - Session 12 — add cluster operations and per-node ACK tracking - - Session 22 — add cluster operation and node-status admin APIs - - Session 27 — add chaos and fault-injection validation -- Notes: - - added a durable `ClusterLease` table with owner, TTL, expiry, and generation-based fencing-token state - - moved leader acquisition in `DistributedLockService` to lease upsert/renew/release primitives while preserving the existing advisory-lock helper methods for non-leader exclusivity - - replaced the advisory-lock-specific deadlock recovery path with lease reconciliation so the transitional cluster heartbeat can reason about durable lease ownership before the full Session 11 refactor lands - - exposed `GET /cluster/lease` and enriched `GET /cluster/leader/status` so operators can inspect current lease owner and fencing-token state - -## Session 11 — Move heartbeat and leader flows onto leases - -- Status: done -- Objective: align membership and leadership around the new lease model -- Files touched: - - `src/distributed-lock/distributed-lock.service.ts` - - `src/distributed-lock/cluster-heartbeat.service.ts` - - `src/distributed-lock/cluster.controller.ts` - - `test/session11/lease-backed-heartbeat.test.js` - - `README.md` - - `ARCHITECTURE_DECISIONS.md` - - `IMPLEMENTATION_STATUS.md` -- Tests added/updated: - - added `test/session11/lease-backed-heartbeat.test.js` to verify lease-derived leader reads, stale lease-owner handling, lease-only leader election, and stale-node cleanup behavior - - re-ran the focused Session 11 regression suite and the repository test suite so Sessions 3-11 continue to pass together after the lease-backed refactor - - validated the edited cluster coordination files with `npm run typecheck` and `npm run build` after removing the remaining generated-client dependency from lease snapshot reads -- Risks: - - `ClusterNode.isLeader` is still retained as a denormalized observability field for compatibility, so later sessions should continue reducing reliance on legacy node flags in any new APIs - - cluster-wide mutating workflows still do not persist operation IDs or per-node ACKs; Session 12 remains responsible for making lease ownership actionable across async workflows - - inter-node transport is still authenticated HTTP rather than mTLS, so this session improves coordination correctness but not network trust boundaries -- Follow-up sessions: - - Session 12 — add cluster operations and per-node ACK tracking - - Session 22 — add cluster operation and node-status admin APIs - - Session 24 — replace ad hoc logging with structured operational and audit logging - - Session 27 — add chaos and fault-injection validation -- Notes: - - heartbeat updates, leader reads, and cluster stats now derive leadership from the active leader lease instead of choosing a leader from `ClusterNode.isLeader` flags - - stale-node cleanup now marks nodes stale and clears denormalized leader flags, but it waits for lease expiry instead of force-electing a replacement from heartbeat recency - - the cluster leader status endpoint now surfaces lease-owner-missing and lease-owner-not-active states explicitly so leadership drift is diagnosable without relying on split-brain heuristics - -## Session 12 — Add cluster operations and per-node ACK tracking - -- Status: done -- Objective: represent cluster-wide mutations as tracked async operations -- Files touched: - - `prisma/schema.prisma` -

- `test/session8/rbac-authorization.test.js` - - `test/session9/audit-logging.test.js` - - `test/session12/cluster-operations.test.js` -- Tests added/updated: - - added `test/session12/cluster-operations.test.js` to verify successful cluster-wide operation tracking and remote ACK failure handling when peer auth is unavailable - - updated the Session 6 regression to assert peer URL construction now lives in the new cluster-operations layer instead of the controller directly - - updated Session 8 and Session 9 controller harnesses so `ClusterController` still instantiates with the new cluster-operations dependency - - re-ran `npm test`, `npm run typecheck`, and `npm run build` after regenerating the Prisma client for the new operation models -- Risks: - - cluster operations are now durable and queryable, but execution is still process-local in-memory orchestration, so restart-resume semantics remain future work - - remote node ACKs still rely on authenticated HTTP responses rather than mTLS-backed service identity or a separate ACK callback channel - - only the current reload and certificate-sync workflows use the operation journal so far; additional cluster-wide mutations still need to adopt the same contract in later sessions -- Follow-up sessions: - - Session 13 — implement staged NGINX config generation and atomic activation - - Session 17 — rework cluster certificate distribution and activation - - Session 22 — add cluster operations and node-status admin APIs - - Session 25 — expand metrics and alerting -- Notes: - - added durable `ClusterOperation` and `ClusterOperationAck` tables so cluster-wide mutations can be tracked independently from lease state - - introduced `ClusterOperationsService` to create operation records, pre-register per-node ACK rows, execute local and remote work, and summarize final success/partial-failure state - - changed `POST /cluster/reload` to return `202 Accepted` with an operation ID and added `GET /cluster/operations` plus `GET /cluster/operations/:operationId` for inspection - - updated cluster-triggered certificate sync broadcasts to use the same operation journal, and the per-node sync endpoint now returns HTTP 500 for tracked failures so remote ACK state is accurate - ---- - -## Phase 4 — Configuration rollout and rollback safety - -## Session 13 — Implement staged NGINX config generation and atomic activation - -- Status: done -- Objective: make config rollout transactional and rollbackable -- Files touched: - - `src/reloader/reloader.service.ts` - - `src/nginx/nginx.service.ts` - - `nginx/nginx.conf` - - `nginx/conf.d/default.conf` - - `docker-entrypoint.sh` - - `README.md` - - `ARCHITECTURE_DECISIONS.md` - - `IMPLEMENTATION_STATUS.md` - - `test/session13/transactional-nginx-rollout.test.js` -- Tests added/updated: - - added `test/session13/transactional-nginx-rollout.test.js` to verify staged release validation, atomic `current` symlink activation, rollback to the prior release on reload failure, and the bootstrap runtime layout wiring - - re-ran `npm test`, `npm run typecheck`, and `npm run build` after the staged rollout changes landed -- Risks: - - the stable loader currently swaps only the managed virtual-host release path; broader NGINX extensibility such as `nginx_custom_code` still remains unsafe until Session 14 narrows or redesigns that surface - - release metadata is currently filesystem-backed inside the container/runtime volume rather than persisted in PostgreSQL, so operators must retain the runtime state directory to preserve local rollout history across node replacement - - certificate and TLS asset paths are still live-system paths outside the staged release tree, so later certificate-hardening sessions must keep config rollout and certificate artifact activation coordinated -- Follow-up sessions: - - Session 14 — restrict or redesign `nginx_custom_code` - - Session 17 — rework cluster certificate distribution and activation - - Session 25 — expand metrics and alerting - - Session 27 — add chaos and fault-injection validation -- Notes: - - reloader deployments now create full staged releases under `/etc/nginx/runtime/releases/<release-id>` instead of clearing `/etc/nginx` in place - - each staged release is validated with a release-specific `nginx -t` config before activation, and activation now swaps the `current` release symlink atomically - - the runtime keeps both `current` and `last-known-good` symlinks, and failed reloads automatically roll back to the previous release before returning an error - - each release writes `lyttle-nginx-release.json` metadata with phase, node, validation output, and rollback details so apply state is inspectable on disk - -## Session 14 — Restrict or redesign `nginx_custom_code` - -- Status: done -- Objective: remove arbitrary config injection risk while preserving advanced extensibility -- Files touched: - - `src/nginx/nginx-custom-code.ts` -

- added `test/session14/nginx-custom-code-guardrails.test.js` to verify allowlisted custom fragments render successfully, dangerous directives are rejected, path-prefix enforcement works, and invalid fragments fail reloads before activation - - re-ran `npm test`, `npm run typecheck`, and `npm run build` after landing the guarded fragment parser so Sessions 3-14 continue to pass together -- Risks: - - `nginx_custom_code` is now constrained to a narrow allowlist, so operators who relied on arbitrary directives will need to move to the reviewed fragment subset or wait for a future structured extensibility model - - proxy management still occurs outside a dedicated API surface today; Session 21 remains responsible for shipping authenticated CRUD and validation workflows around proxy state instead of direct database mutation -- Follow-up sessions: - - Session 15 — add strict domain validation and safe process execution - - Session 21 — add proxy management API - - Session 29 — reconcile README, architecture docs, and runbooks with reality -- Notes: - - raw `nginx_custom_code` injection has been replaced with a validated fragment parser that only accepts reviewed server-level directives and `location` blocks - - `root` and `alias` paths now must stay within `NGINX_CUSTOM_CODE_ALLOWED_PATH_PREFIXES`, and directory creation derives from the validated fragment AST instead of regex extraction from raw text - - invalid custom fragments now fail the staged reload immediately, preventing unsafe or unsupported config from reaching `nginx -t`, activation, or side-effectful directory creation - ---- - -## Phase 5 — Certificate lifecycle redesign - -## Session 15 — Add strict domain validation and safe process execution - -- Status: done -- Objective: reject malformed domains early and stop using unsafe shell interpolation -- Files touched: - - `src/utils/domain-utils.ts` -

- `IMPLEMENTATION_STATUS.md` - - `test/session15/domain-validation-and-safe-process.test.js` -- Tests added/updated: - - added `test/session15/domain-validation-and-safe-process.test.js` to verify strict FQDN normalization, malformed-domain rejection, wildcard HTTP-01 issuance rejection, safe OpenSSL argument execution, and safe certificate storage names in generated NGINX config - - ran `npm run typecheck`, `npm test`, and `npm run build` successfully after landing the domain-validation and process-execution changes - - ran `npm run lint`; the repo-wide lint command still reports pre-existing unrelated formatting debt in untouched files, but the Session 15 files were cleaned up and do not block typecheck/build/test verification -- Risks: - - wildcard issuance remains intentionally blocked until Session 18 introduces DNS-01 or another wildcard-safe ACME strategy - - certificate lifecycle durability, retry journaling, and resumable issuance state are still pending Session 16 and Session 17 - - private keys and backup artifacts are still not encrypted at rest; Session 19 and Session 20 remain responsible for that hardening -- Follow-up sessions: - - Session 16 — add certificate order state machine - - Session 17 — rework cluster certificate distribution and activation - - Session 18 — harden the ACME strategy for clustered production - - Session 19 — encrypt private key material at rest - - Session 20 — harden backup, export, import, and restore flows - - Session 26 — expand automated regression coverage further -- Notes: - - domain handling now enforces lowercase normalized FQDNs with punycode conversion, explicit wildcard rules, and early rejection of path separators, whitespace, control characters, and IP addresses - - certificate storage directories now derive from safe deterministic storage IDs instead of raw domain strings, preventing wildcard/path characters from leaking into filesystem layout or generated NGINX certificate paths - - OpenSSL, certbot, and NGINX invocations in the certificate and TLS flows now use argument arrays via a shared `execFile`-based helper instead of shell-interpolated command strings - - route params and certificate DTO domain arrays are validated and normalized before the certificate services run, reducing the chance of malformed input reaching DNS lookups, certbot, OpenSSL, or archive generation - -## Session 16 — Add certificate order state machine - -- Status: done -- Objective: model certificate issuance as a durable workflow -- Files touched: - - `prisma/schema.prisma` - - `prisma/migrations/20260524191500_session16_certificate_orders/migration.sql` -

- `test/session16/certificate-order-state-machine.test.js` -- Tests added/updated: - - added `test/session16/certificate-order-state-machine.test.js` to verify durable self-signed order history, artifact-version tracking, failed ACME order persistence, and manual retry/resume behavior - - updated the Session 15 certificate-service harness for the new order-service dependency - - ran `npm run prisma:generate`, `npm run typecheck`, the focused Session 16 regression, the full `npm test` suite, and `npm run build` successfully after landing the new workflow models and APIs -- Risks: - - order activation is still local-first and immediate; Session 17 remains responsible for separating issuance from cluster-wide distribution and ACK-driven activation - - uploaded/imported orders are queryable but not automatically retryable because replaying those workflows safely still requires operator-supplied certificate material and later restore hardening - - certificate artifact versions currently store plaintext PEMs alongside the existing certificate table, so Session 19 remains responsible for encryption-at-rest before this history is suitable for production key storage -- Follow-up sessions: - - Session 17 — rework cluster certificate distribution and activation - - Session 18 — harden the ACME strategy for clustered production - - Session 19 — encrypt private key material at rest - - Session 25 — expand metrics and alerting -- Notes: - - added durable `CertificateOrder`, `CertificateOrderEvent`, and `CertificateArtifactVersion` models so certificate workflows now persist their lifecycle, retry/backoff history, and artifact-version metadata - - ACME issuance, uploaded certificates, and self-signed certificates now create order records and transition through explicit lifecycle states instead of relying only on ephemeral logs and the final `Certificate` row - - failed ACME issuance now records per-order retry scheduling, and operators can inspect or manually retry orders through the new `GET /certificates/orders`, `GET /certificates/orders/:id`, and `POST /certificates/orders/:id/retry` APIs - - order read APIs intentionally omit raw PEM payloads even though artifact history is now persisted, keeping lifecycle observability separate from private-key export flows - -## Session 17 — Rework cluster certificate distribution and activation -

- `test/session17/certificate-distribution-and-rollback.test.js` -- Tests added/updated: - - added `test/session17/certificate-distribution-and-rollback.test.js` to verify failed rollout retries reuse stored artifacts and rollback reactivates the prior successful artifact version - - updated the Session 15 and Session 16 certificate harnesses so they cover the new activation-time certificate validation and NGINX reload steps - - ran `npm run prisma:generate`, `npm run typecheck`, the focused Session 15-17 certificate suites, the full `npm test` suite, and `npm run build` successfully after landing the new rollout flow -- Risks: - - cluster artifact activation now waits for node ACKs, but peer transport is still authenticated HTTP rather than mTLS-backed service identity - - artifact rollout state is durable, but rollback and retry visibility is still routed through certificate-order detail plus the cluster-operation journal; richer operator-focused cluster/certificate views remain future work for Session 22 - - activation failure recovery currently relies on retrying the stored artifact and on the existing active certificate row for safe rollback; broader fault-injection proof remains planned for Session 27 -- Follow-up sessions: - - Session 18 — harden the ACME strategy for clustered production - - Session 22 — add cluster operations and node-status admin APIs - - Session 25 — expand metrics and alerting - - Session 27 — add chaos and fault-injection validation -- Notes: - - issuance, upload, and self-signed generation now create durable certificate artifacts first and only update the live `Certificate` row after the artifact has been ACKed across the cluster - - certificate artifacts now persist rollout metadata (`isCurrent`, `distributionStatus`, `distributionOperationId`, `distributionCompletedAt`) and order detail responses surface the latest distribution ACK summary - - failed activation retries now reuse the existing artifact instead of reissuing certificate material, reducing unnecessary issuance churn and preserving rollback targets - - added admin rollback support that reactivates the prior successful artifact version through the same cluster operation + ACK path used for forward activation - -## Session 18 — Harden the ACME strategy for clustered production - -- Status: done -- Objective: make challenge handling explicit, durable, and cluster-safe -- Files touched: - - `prisma/schema.prisma` -

- `IMPLEMENTATION_STATUS.md` - - `test/session15/domain-validation-and-safe-process.test.js` - - `test/session18/acme-strategy-hardening.test.js` -- Tests added/updated: - - added `test/session18/acme-strategy-hardening.test.js` to verify Nest-managed ACME strategy resolution, production-hardened HTTP-01 behavior, explicit wildcard/DNS rejection, challenge inspection delegation, and challenge-serving lifecycle behavior - - updated the Session 15 wildcard regression so it now asserts wildcard ACME requests are rejected because the hardened flow must not require DNS TXT changes - - updated the Session 16 and Session 17 harnesses for the new in-app ACME service dependency and re-ran the focused Session 3 / 15 / 16 / 17 / 18 suites locally after the refactor -- Risks: - - the validated Session 18 flow is intentionally limited to non-wildcard certificates so clustered issuance stays production-safe without operator DNS TXT changes - - built-in challenge inspection now focuses on shared HTTP-01 publication / cleanup / validation state; richer per-order observability and operator workflows remain future work - - private keys and artifact history are still stored plaintext until Session 19 lands encryption-at-rest -- Follow-up sessions: - - Session 19 — encrypt private key material at rest - - Session 20 — harden backup, export, import, and restore flows - - Session 22 — add cluster operations and node-status admin APIs - - Session 25 — expand metrics and alerting - - Session 29 — reconcile README, architecture docs, and runbooks with reality -- Notes: - - replaced the prior shell-hook/certbot orchestration path with a Nest-managed `AcmeService` built on `acme-client`, so the hardened HTTP-01 challenge lifecycle now stays inside the application - - the built-in HTTP-01 flow stores publication, cleanup, expiry, and finalization state in `AcmeChallenge`, and operators can inspect recent challenge rows through `GET /certificates/challenges` - - wildcard orders are now rejected explicitly because the production-hardened Session 18 scope requires cluster-safe issuance without any DNS TXT record changes - - the runtime now persists the ACME account key under `ACME_ACCOUNT_PRIVATE_KEY_PATH` instead of depending on external certbot account state and hook scripts -

- `IMPLEMENTATION_STATUS.md` - - `test/session19/private-key-encryption-at-rest.test.js` -- Tests added/updated: - - added `test/session19/private-key-encryption-at-rest.test.js` to verify legacy-plaintext backfill, key-version re-encryption, encrypted artifact/certificate storage, and decrypted export behavior - - ran the focused Session 19 regression with the repository's Node test runner and `ts-node/register/transpile-only` - - ran `npm run typecheck` after wiring the new encryption service through certificate issuance, activation, sync, and backup flows -- Risks: - - backup ZIP files and explicit certificate-export responses still contain decrypted PEM material today; Session 20 remains responsible for encrypting artifacts and adding integrity validation around backup/restore flows - - the shipped provider abstraction currently implements only the local master-key envelope backend, so operator-facing Vault/KMS/HSM integrations and rotation APIs remain future work for Session 23 - - production deployments must now supply `PRIVATE_KEY_ENCRYPTION_MASTER_KEY`; the development/test fallback should not be used for hardened environments -- Follow-up sessions: - - Session 20 — harden backup, export, import, and restore flows - - Session 23 — add security administration APIs - - Session 29 — reconcile README, architecture docs, and runbooks with reality -- Notes: - - certificate private keys are now envelope-encrypted before persistence in both `Certificate` and `CertificateArtifactVersion`, with per-record `keyEncryption` metadata that stores scheme/provider/key-version details for future rotation - - startup now migrates legacy plaintext private keys already present in the database and re-encrypts stored material when `PRIVATE_KEY_ENCRYPTION_KEY_VERSION` changes - - certificate sync, activation, backup, import, and export paths now decrypt private keys only at the moment they are needed instead of assuming the database returns plaintext PEMs - -## Session 20 — Harden backup, export, import, and restore flows - -- Status: done -- Objective: make backup and recovery flows encrypted, validated, and authorized -- Files touched: - - `.env.example` -

- added `test/session20/backup-hardening.test.js` to verify encrypted backup creation, signed-manifest verification, tamper rejection, server-side restore, and mismatched-key import rejection - - updated the Session 8 RBAC regression so raw certificate export now requires `platform-admin` while `security-admin` retains encrypted backup/import/restore access - - updated the Session 9 audit regression so denied raw certificate export attempts are recorded as audited authorization failures - - updated the Session 19 private-key regression fixtures to use valid certificate material now that Session 20 import validation rejects malformed placeholder PEMs - - ran the focused Session 8/9/19/20 regression suites plus `npm run typecheck`, `npm test`, and `npm run build` after landing the backup hardening changes -- Risks: - - the current backup envelope uses a locally configured symmetric key and HMAC signature; external KMS/Vault/HSM-backed backup-key custody and rotation workflows remain future work for Session 23 - - restore currently recreates active certificate rows but does not yet rebuild higher-level order/artifact history from older backups, so operators should still treat backup restore as certificate-state recovery rather than full workflow replay - - legacy plaintext `.zip` backups remain downloadable for backward compatibility, but the hardened verify/restore flow intentionally refuses to trust or import them -- Follow-up sessions: - - Session 23 — add security administration APIs - - Session 27 — add chaos and fault-injection validation - - Session 29 — reconcile README, architecture docs, and runbooks with reality -- Notes: - - backups are now written as encrypted `.lyttlebackup` artifacts with a signed manifest and per-entry SHA-256 checksums instead of plaintext ZIP archives - - added `POST /certificates/backup/:filename/verify` and `POST /certificates/backup/:filename/restore` so operators can verify and restore encrypted backups server-side without manual plaintext extraction - - direct import now validates PEM structure, key/certificate matching, SAN/CN domain coverage, and validity-window consistency before accepting certificate material - - raw `GET /certificates/backup/export/:id` remains available as a break-glass flow but is now restricted to `platform-admin` and continues to be audited explicitly - ---- - -## Phase 7 — Operational API expansion - -## Session 21 — Add proxy management API - -- Status: done -- Objective: manage proxy config through authenticated API endpoints instead of direct DB mutation -- Files touched: -

- `README.md` - - `ARCHITECTURE_DECISIONS.md` - - `IMPLEMENTATION_STATUS.md` - - `test/session21/proxy-management-api.test.js` -- Tests added/updated: - - added `test/session21/proxy-management-api.test.js` to verify authenticated proxy CRUD access rules, validation-first create/update behavior, duplicate-domain rejection, stored/draft validation endpoints, and upstream-resolution diagnostics - - validated the focused Session 21 regression locally together with repository type-check/build verification after wiring the new module into `AppModule` -- Risks: - - proxy changes now surface a `reloadRequired` desired-state hook, but they still rely on operators or later orchestration to trigger the existing cluster reload flow explicitly - - proxy ownership conflict checks currently protect direct and wildcard-overlap domain collisions, but broader rollout-policy/versioning semantics remain future work for Session 22 and Session 25 -- Follow-up sessions: - - Session 22 — add cluster operations and node-status admin APIs - - Session 24 — replace ad hoc logging with structured operational and audit logging - - Session 25 — expand metrics and alerting - - Session 26 — add automated test harness and baseline coverage -- Notes: - - added `GET /proxies`, `GET /proxies/:id`, `POST /proxies`, `PATCH /proxies/:id`, and `DELETE /proxies/:id` with explicit RBAC (`viewer` for reads, `platform-admin` for config mutations) - - added `POST /proxies/validate`, `POST /proxies/:id/validate`, and `POST /proxies/:id/test-upstream` so operators can validate proxy payloads and inspect upstream reachability before rollout - - proxy writes now validate domains, upstream target shape, guarded custom NGINX fragments, and conflicting domain ownership before persistence, reducing the chance of invalid config entering the desired state store - - mutating responses now include a lightweight `configChange` hint that points operators to `/cluster/reload` until later sessions add fuller desired-state versioning and rollout APIs - -## Session 22 — Add cluster operations and node-status admin APIs -

- `test/session22/cluster-admin-apis.test.js` -- Tests added/updated: - - added `test/session22/cluster-admin-apis.test.js` to verify the new cluster overview, inactive-node listing, per-node config/certificate detail, filtered operation inspection, and stable not-found contracts - - updated the Session 8 and Session 9 controller harnesses to provide the new `PrismaService` dependency required by the expanded `ClusterController` - - ran `npm run typecheck`, `npm run build`, the focused Session 22 regression, and the full `npm test` suite successfully after landing the new APIs -- Risks: - - node-level config and certificate views still derive primarily from the current operation journal plus local runtime/DB inspection; richer desired-state drift tracking and per-node metrics remain future work for Sessions 24 and 25 - - remote node runtime detail is still limited to what the latest ACK payload exposes, because inter-node transport remains request/response HTTP rather than a dedicated status stream - - the local certificate inventory is sourced from the shared database and represents the cluster control-plane view, not an independently attested on-disk filesystem scan of every remote node -- Follow-up sessions: - - Session 23 — add security administration APIs - - Session 24 — replace ad hoc logging with structured operational and audit logging - - Session 25 — expand metrics and alerting - - Session 26 — add automated test harness and baseline coverage -- Notes: - - added `GET /cluster/status` as a single operator-facing overview that combines cluster counts, lease/leader diagnostics, active node summaries, and recent operation state - - expanded `GET /cluster/operations` with node/type/status filtering and normalized status-summary metadata so async operation responses are easier to consume consistently - - added `GET /cluster/nodes/:nodeId`, `GET /cluster/nodes/:nodeId/config`, and `GET /cluster/nodes/:nodeId/certificates` so operators can inspect per-node convergence, local runtime release state, and recent certificate rollout ACKs - - added public reloader runtime-release inspection so the node config API can expose current and last-known-good release metadata without requiring shell access to the container - -## Session 23 — Add security administration APIs -

- `docs/runbooks/security-break-glass.md` - - `test/session23/security-admin-apis.test.js` -- Tests added/updated: - - added `test/session23/security-admin-apis.test.js` to verify security posture review endpoints, API-key rotation planning with bridge-token issuance, private-key re-encryption maintenance, the deferred internal-cert rotation hook, and audited denied/successful access patterns - - validated the edited Session 23 files with targeted error checks before running the focused regression suite - - ran targeted Session 23 verification plus repository type-check/build validation after wiring the new module into `AppModule` -- Risks: - - API-key rotation is now explicit and auditable, but it is still a manual secret-store + redeploy workflow rather than hot-reloaded in-app credential persistence - - internal node mTLS is still not implemented, so `POST /security/rotate/internal-certs` currently documents the future contract and prerequisites instead of rotating live node certificates - - backup-key rotation still depends on operators creating fresh encrypted artifacts after changing `BACKUP_ENCRYPTION_KEY_VERSION`; older artifacts remain protected by the previous configured backup key until they are replaced or retired -- Follow-up sessions: - - Session 24 — replace ad hoc logging with structured operational and audit logging - - Session 25 — expand metrics and alerting - - Session 29 — reconcile README, architecture docs, and runbooks with reality -- Notes: - - added a dedicated `/security` administration surface for posture review (`status`, `policy`, `secrets/health`, `access-review`) under `security-admin` RBAC - - added an audited `POST /security/rotate/api-key` planning endpoint for safe overlap-based legacy API-key rotation and optional bearer-token bridge issuance when `AUTH_JWT_SECRET` is available - - added `POST /security/rotate/private-key-encryption` as the operator-facing hook for Session 19 key-version migration so stored certificate private keys can be re-encrypted after a master-key rotation - - reserved `POST /security/rotate/internal-certs` as the future internal-PKI rotation contract while making the current mTLS gap explicit in both API responses and documentation - - documented the break-glass export/API-key overlap procedures in `docs/runbooks/security-break-glass.md` - ---- - -## Phase 8 — Logging, metrics, and SRE readiness - -## Session 24 — Replace ad hoc logging with structured operational and audit logging - -- Status: done -- Objective: make logs machine-parseable, traceable, and safe for centralized collection -- Files touched: -

- `README.md` - - `ARCHITECTURE_DECISIONS.md` - - `IMPLEMENTATION_STATUS.md` - - `test/session24/structured-logging.test.js` -- Tests added/updated: - - added `test/session24/structured-logging.test.js` to verify structured JSON operational log entries, request/actor/operation context propagation, correlation header behavior, and secret redaction - - ran the focused Session 24 logging regression directly with the repository test runner - - ran `npm run typecheck`, `npm run build`, and the full `npm test` suite successfully after landing the structured logging changes -- Risks: - - the in-memory `/logs` buffer is intentionally process-local and non-durable; operators should treat stdout log shipping as the primary retention path - - many existing service messages still originate from historical plain-text strings, so the new logger structures context around them but does not rewrite every message into a domain-specific event schema yet - - audit persistence still shares the primary application database; this session cleanly separates operational vs audit outputs, but it does not make audit writes resilient to database outages on its own -- Follow-up sessions: - - Session 25 — expand metrics and alerting - - Session 27 — add chaos and fault-injection validation - - Session 28 — upgrade CI/CD and release gating - - Session 29 — reconcile README, architecture docs, and runbooks with reality -- Notes: - - replaced synchronous local file logging with structured JSON stdout/stderr emission plus a bounded in-memory buffer for `GET /logs` - - added async request-scoped logging context so correlation IDs, actor identity, request metadata, and cluster operation IDs flow through runtime logs automatically - - routed HTTP lifecycle and exception logs through the structured logger while keeping audit records on the separate `AuditEvent` / `GET /audit` path - - added recursive secret redaction for common sensitive keys and PEM private-key material before operational logs are emitted - -## Session 25 — Expand metrics and alerting - -- Status: done -- Objective: add observability for leases, config apply, cert orders, backups, and DB health -- Files touched: - - `.env.example` - - `README.md` -

- `src/metrics/metrics.controller.ts` - - `src/metrics/metrics.service.ts` - - `test/session25/metrics-and-alerting.test.js` -- Tests added/updated: - - added `test/session25/metrics-and-alerting.test.js` to verify the expanded JSON/Prometheus metrics surface, partial metrics collection failure handling, and the new `/health/dependencies` + `/health/deep` drilldown endpoints - - validated the edited health/metrics files with targeted IDE error checks before running repository verification - - ran the focused Session 25 regression, `npm run typecheck`, `npm run build`, and the full `npm test` suite after landing the observability changes -- Risks: - - the new metrics are primarily current-state gauges built from live DB/filesystem reads and in-memory health state, so historical time-series retention and SLO alert tuning still depend on external Prometheus/Grafana infrastructure - - backup freshness metrics currently reflect the local node backup directory only; cluster-wide backup orchestration and off-node retention validation remain future work - - metrics and health drilldowns improve diagnosability, but they do not themselves prove recovery behavior under fault injection; Session 27 remains responsible for that evidence -- Follow-up sessions: - - Session 26 — add automated test harness and baseline coverage - - Session 27 — add chaos and fault-injection validation - - Session 29 — reconcile README, architecture docs, and runbooks with reality -- Notes: - - expanded `GET /metrics` and `GET /metrics/json` to expose certificate, proxy, dependency-health, leader-lease, cluster-operation, certificate-order, backup, and metrics-collection status gauges - - added `GET /health/dependencies` and `GET /health/deep` so operators can inspect dependency drilldowns and combined probe state without inferring detail from readiness alone - - documented configurable freshness thresholds for metrics/alerting in `.env.example` and added `docs/runbooks/monitoring-alerts.md` with recommended Prometheus alert rules for the newly exposed signals - ---- - -## Phase 9 — Test harness and release gates - -## Session 26 — Add automated test harness and baseline coverage - -- Status: done -- Objective: formalize the repository test harness into explicit unit, integration, and e2e suites with baseline coverage for critical workflows -- Files touched: - - `package.json` - - `README.md` - - `ARCHITECTURE_DECISIONS.md` - - `IMPLEMENTATION_STATUS.md` - - `src/auth/auth.service.ts` - - `test/setup/register.js` - - `test/test-harness.config.js` - - `test/run-suite.js` - - `test/session26/auth-service-unit.test.js` -- Tests added/updated: - - added `test/session26/auth-service-unit.test.js` to provide direct unit coverage for API-key identity resolution and bearer-token validation without booting a Nest application - - updated `src/auth/auth.service.ts` so API-key authentication returns cloned roles/scopes/audience arrays after the new unit harness exposed shared mutable identity state - - classified the full repository test inventory into explicit `unit`, `integration`, and `e2e` suites through `test/test-harness.config.js` - - added a shared preload step in `test/setup/register.js` so all test runs consistently load `reflect-metadata` and default `NODE_ENV=test` - - added `npm run test`, `npm run test:unit`, `npm run test:integration`, `npm run test:e2e`, `npm run test:coverage`, and `npm run test:list` - - updated `npm run verify` so automated tests are now part of the default repo verification contract - - verified the new harness with `npm run test:list`, `npm run test:unit`, `npm run test:integration`, `npm run test:e2e`, `npm run test`, `npm run test:coverage`, `npm run typecheck`, and `npm run build` -- Risks: - - the current harness still focuses on deterministic in-process regression coverage; full chaos and failure-mode proof remains the responsibility of Session 27 - - coverage reporting now exists, but minimum thresholds and CI enforcement remain future work for Session 28 - - some suites intentionally exercise filesystem/process shims and emit verbose Nest logs; later sessions may still want finer-grained logging controls for CI readability -- Follow-up sessions: - - Session 27 — add chaos and fault-injection validation - - Session 28 — upgrade CI/CD and release gating -- Notes: - - the harness now enforces explicit classification of every `test/**/*.test.js` file and fails fast if any test file is untracked or missing from the suite manifest - - baseline coverage pillars are now explicit for auth, health, leases, config generation, and certificate-order transitions - - the repository continues to use the built-in Node.js test runner plus `ts-node/register/transpile-only`, avoiding a second test framework while still adding suite-level ergonomics and coverage entrypoints - -## Session 27 — Add chaos and fault-injection validation - -- Status: done -- Objective: prove recovery and coordination claims with reproducible failure tests -- Files touched: - - `package.json` - - `README.md` - - `ARCHITECTURE_DECISIONS.md` - - `IMPLEMENTATION_STATUS.md` - - `test/test-harness.config.js` - - `test/session27/chaos-fault-injection.test.js` -- Tests added/updated: - - added `test/session27/chaos-fault-injection.test.js` to deterministically inject a PostgreSQL readiness outage, stale-leader crash recovery, supervised NGINX master failure, staged-config rollback, inter-node communication failure, and partial certificate activation failure - - added `npm run test:chaos` plus an explicit `chaos` suite classification in `test/test-harness.config.js` so the new failure drills can run independently or as part of `npm run test` - - verified `npm run test:chaos`, `npm run test`, `npm run test:list`, `npm run typecheck`, and `npm run build` after landing the Session 27 suite -- Risks: - - the chaos suite is intentionally deterministic and in-process, so it validates application recovery contracts without replacing later environment-level Swarm fault drills or external dependency chaos exercises - - node-to-node transport is still authenticated HTTP rather than mTLS, so the injected node communication failures prove ACK/error handling behavior but do not yet validate a future mTLS transport stack -- Follow-up sessions: - - Session 28 — upgrade CI/CD and release gating - - Session 29 — reconcile README, architecture docs, and runbooks with reality - - Session 30 — final production-readiness validation pass -- Notes: - - the repository now has a first-class chaos/fault-injection suite instead of relying only on unit/integration/e2e regressions for recovery claims - - the new suite exercises the exact failure modes called out in the implementation plan: DB outage, leader crash with lease expiry/re-election, NGINX crash, bad config activation rollback, node comms failure, and partial certificate activation failure - - `npm run test` now includes the chaos suite automatically through the `all` classification, while `npm run test:chaos` provides a focused recovery-proof entrypoint for operators and CI - -## Session 28 — Upgrade CI/CD and release gating -

- added `scripts/ci/assert-coverage.js` and `npm run test:coverage:ci` so CI enforces minimum line/branch/function coverage thresholds while still running the full Session 3-27 regression suite - - ran `npm run test:coverage:ci`, `npm run test`, `npm run typecheck`, `npm run build`, `npm run audit:prod`, and focused Session 28 verification after refreshing the lockfile with the new transitive dependency overrides -- Risks: - - the repo still has broad Prettier formatting debt across existing TypeScript files, so the new CI lint gate intentionally disables only the `prettier/prettier` rule while continuing to fail on semantic ESLint issues - - the container scan currently ignores unfixed high/critical CVEs to avoid blocking releases on base-image issues with no upstream patch yet; operators should still review scan output and keep base images current - - image publication is now gated on GitHub Actions success, but branch protections and required-status-check enforcement must still be enabled in the GitHub repository settings to make the policy mandatory for merges -- Follow-up sessions: - - Session 29 — reconcile README, architecture docs, and runbooks with reality - - Session 30 — final production-readiness validation pass -- Notes: - - replaced the old image-build-only workflow with explicit GitHub Actions jobs for lint, typecheck, tests with coverage thresholds, build, production dependency audit, and container scanning - - GHCR publication now runs only on pushes to `main` and only after every verification and scan job succeeds, preventing image publication from bypassing the new release gates - - added targeted npm overrides for `@hono/node-server`, `@prisma/streams-local`/`ajv`, and `fast-uri` so the production dependency audit passes without waiting for a broader Prisma release - - added repo-level CI scripts (`lint:ci`, `test:coverage:ci`, `audit:prod`, `verify:ci`) so local and CI verification contracts are explicit and repeatable - ---- - -## Phase 10 — Documentation and final validation -

- validated the updated docs against the current route surface, package scripts, workflow files, and existing runbooks before close-out -- Risks: - - Session 30 final production-readiness validation is still required before any production-ready claim can be made - - internal node traffic is still authenticated HTTP rather than mTLS, and the docs now call that out explicitly instead of softening the gap - - manual NGINX config rollback is still an operator procedure around desired-state reversion and automatic rollback behavior, not a dedicated API -- Follow-up sessions: - - Session 30 — final production-readiness validation pass -- Notes: - - replaced the oversized README with a shorter, reality-based overview that focuses on shipped behavior, current deployment expectations, and explicit limitations - - added a dedicated `docs/architecture/current-architecture.md` reference that explains the current monolith + NGINX runtime shape, trust boundaries, workflows, and unresolved architectural limits - - added operator runbooks for leader failure, encrypted restore, NGINX config rollback, certificate issuance failure, and credential rotation -

- no code-level tests were added for this documentation-and-validation session - - ran `node -v` and `npm -v` to confirm the pinned toolchain is available in the workspace session (`24.16.0` / `11.15.0`) - - ran `npm run verify:ci` as the final repository validation contract; the first run exposed a stale README omission around explicit `CLUSTER_CONTROL_PORT` guidance, which Session 30 corrected before the verification suite was rerun to green - - the CI-grade verification pass exercises Prisma client generation, linting, typechecking, coverage-gated tests, build validation, and production dependency audit in one contract -- Risks: - - rollout still requires explicit acceptance of the residual items in `PRODUCTION_DEFERMENT_REGISTER.md`, especially the lack of internal mTLS, incomplete Docker runtime hardening, baseline rate limiting, and environment-driven secret ingestion - - the repository now has a final readiness position, but some operational controls still depend on external platform configuration rather than in-repo code alone (for example isolated control-plane networking, Swarm/external secret injection, GitHub branch protections, and external monitoring/alert delivery) -- Follow-up sessions: none -- Notes: - - published `FINAL_PRODUCTION_CHECKLIST.md` to reconcile every numbered assessment section and capture the final go-live checklist - - published `PRODUCTION_DEFERMENT_REGISTER.md` to track accepted residual gaps, compensating controls, and recommended future work - - updated the README and current-architecture docs so they no longer describe Session 30 as pending and instead point operators to the final validation artifacts - - recorded ADR-033 to formalize the final-readiness posture: controlled production rollout for the documented current architecture, with explicit deferment sign-off instead of implied parity with the ideal target architecture diff --git a/PRODUCTION_DEFERMENT_REGISTER.md b/PRODUCTION_DEFERMENT_REGISTER.md index d36740a..bd19c7d 100644 --- a/PRODUCTION_DEFERMENT_REGISTER.md +++ b/PRODUCTION_DEFERMENT_REGISTER.md @@ -2,7 +2,7 @@ _Date: 2026-05-28_ -This register captures residual gaps that Session 30 intentionally leaves visible instead of silently absorbing into a broad "production-ready" label. +This register captures residual gaps that remain intentionally visible instead of being silently absorbed into a broad "production-ready" label.

-## 1.5 Certificate issuance and distribution is not robust enough for clustered production - -### Findings - -#### A. certificate state machine is too weak -The system stores some certificate status metadata, but it does not model a full order lifecycle such as: -- requested -- authorizing -- challenge-published -- validation-pending -- issued -- distributing -- activated -- failed -- rollback -- revoked - -**Impact:** -- poor visibility -- weak recovery after mid-flight failure -- hard to reason about certbot/ACME retries safely - -#### B. issuance uses shell commands with interpolated user/domain data -`CertificateService` and `TlsConfigService` build shell commands using string interpolation. -Domain DTOs only validate that values are non-empty strings. - -**Impact:** -- command injection risk -- path traversal / invalid path materialization risk -- malformed domain values can poison certbot, OpenSSL, filesystem paths, or generated NGINX config - -#### C. cert storage path uses raw domain values -Certificate directories are built from the primary domain. -Without strict canonical validation, this is unsafe. - -#### D. certbot account/certificate metadata is not persisted in Swarm config -`docker-compose.swarm.yml` defines no persistent volumes for: -- `/etc/letsencrypt` -- `/etc/nginx/ssl` -- `/var/www/certbot` -- backup storage - -Even if certificate PEMs are stored in PostgreSQL, loss of local certbot account metadata is still operationally dangerous. - -#### E. challenge serving is globally reachable, but issuance coordination is still fragile -The ACME challenge-from-DB design is directionally correct for a cluster, but issuance coordination still relies on advisory locks + DB bookkeeping without a stronger lease/fencing model. - -#### F. rate-limit handling is naive -The rate-limit logic counts local DB records by string `contains` on domains. -This is not a reliable Let’s Encrypt rate-limit model. - -#### G. failed-cert retry logic may repeatedly churn without strong backoff orchestration across nodes -The current model is better than no retry, but still not robust enough for fleet-wide issuance incidents. -

- disaster-recovery bundle -- encrypt all backups -- add integrity manifest + signing -- add retention/rotation policy -- validate imported certificates before acceptance -- support point-in-time recovery for database state -- support cluster restore with node reconciliation - ---- - -## 2.4 Leader election is not strong enough for high-stakes coordination - -### Findings - -Current approach uses PostgreSQL advisory locks plus DB booleans. -Problems include: -- no fencing token / generation counter -- lock state and DB state can diverge -- deadlock recovery logic comments overstate what `pg_advisory_unlock_all()` can do from a single session -- lock management is tied to the general Prisma client rather than an isolated lock session -- leader intent is duplicated across services - -### Impact - -Under restart storms, DB hiccups, or timing races, this can still create inconsistent control-plane behavior. - -### Required changes - -Use a real lease model: -- `cluster_leases` table or dedicated coordination backend -- fields: - - `lease_name` - - `owner_node_id` - - `generation` - - `expires_at` - - `renewed_at` -- leader operations must include the active generation/fencing token -- stale generation writes must be rejected -- one component should own leader/lease decisions centrally -- optionally move to etcd/Consul if stronger consensus is required -

Admin/API request reaches **any node** -2. Receiving node authenticates/authorizes request -3. Request is forwarded to leader over internal mTLS, or leader is resolved and the request is proxied internally -4. Leader creates a **certificate order record** with idempotency key -5. Leader acquires a lease/fencing token for issuance -6. Leader publishes ACME challenge records to shared storage -7. All nodes serve challenge responses from shared storage -8. Leader finalizes ACME order -9. New cert/key bundle is encrypted and stored centrally -10. Desired-state version is incremented -11. Each node pulls the bundle, validates it locally, writes atomically, runs `nginx -t`, reloads, and ACKs success/failure -12. Leader reports completion only after required ACK policy is met - -### ACK policy options - -- `all-nodes` -- `majority` -- `at-least-one-per-region` -- `best-effort` - -For certificate activation, I strongly recommend: -- **all eligible nodes ACK** before the operation is considered complete -- failure should leave old cert active where possible - ---- - -## 5.3 Stronger coordination model - -Replace advisory-lock-only logic with: -- lease record with expiration -- generation number -- idempotency keys on all mutating requests -- operation journal/event table -- per-node apply acknowledgements - -Suggested tables: -- `ClusterLease` -- `ClusterOperation` -- `ClusterOperationAck` -- `DesiredConfigVersion` -- `NodeAppliedConfigVersion` -- `CertificateOrder` -- `CertificateArtifactVersion` - ---- - -# 6.
