+# Sprint 1200_001_004 · Router Rate Limiting · Service Migration (AdaptiveRateLimiter)
+
+## Topic & Scope
+- Close the planned migration of `AdaptiveRateLimiter` (Orchestrator) into Router rate limiting.
+- Confirm whether any production HTTP paths still enforce service-level rate limiting and therefore require migration.
+- **Working directory:** `src/Orchestrator/StellaOps.Orchestrator`.
+- **Evidence:** `src/__Libraries/StellaOps.Router.Gateway/RateLimit/` (router limiter exists) and Orchestrator code search indicates `AdaptiveRateLimiter` is not wired into HTTP ingress (library-only).
+
+## Dependencies & Concurrency
+- Depends on: `SPRINT_1200_001_001`, `SPRINT_1200_001_002`, `SPRINT_1200_001_003` (rate limiting landed in Router).
+- Safe to execute in parallel with Sprint 5/6 since no code changes are required for this closure.
+
+## Documentation Prerequisites
+- `docs/implplan/SPRINT_1200_001_000_router_rate_limiting_master.md`
+- `docs/modules/router/architecture.md`
+- `docs/modules/orchestrator/architecture.md`

+| 3 | RRL-04-003 | DONE | Update master tracker | Router | Update `SPRINT_1200_001_000_router_rate_limiting_master.md` to reflect closure outcome. |
+
+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2025-12-17 | Sprint created and closed as N/A: `AdaptiveRateLimiter` appears to be a library-only component in Orchestrator (tests + core) and is not wired into HTTP ingress; no service-level HTTP rate limiting was found to migrate. | Automation |
+
+## Decisions & Risks
+- **Decision:** Close Sprint 4 as N/A (no production wiring found). If Orchestrator (or any service) introduces HTTP-level rate limiting, open a dedicated migration sprint under that service’s working directory.
+- **Risk:** Double-limiting during future migration if both service-level and router-level limiters are enabled. Mitigation: migration guide + staged rollout (shadow mode), and remove service-level limiters after router limits verified.
+
+## Next Checkpoints
+- None (closure sprint).

+
+## Decisions & Risks
+- **Decision:** Integration tests require Docker; they are opt-in (skipped unless explicitly enabled) to keep `dotnet test StellaOps.Router.slnx` runnable without Docker.
+- **Risk:** Flaky timing around fixed-window boundaries. Mitigation: assert ranges (not exact seconds) and use small windows with slack.

+# Sprint 1200_001_006 · Router Rate Limiting · Documentation & Rollout Prep
+
+## Topic & Scope
+- Publish user-facing configuration guide and ops runbook for Router rate limiting.
+- Update Router module docs to reflect the new centralized rate limiting feature and where it sits in the request pipeline.
+- Add migration guidance to avoid double-limiting during rollout.
+- **Working directory:** `docs/`.
+- **Evidence:** `docs/router/`, `docs/operations/`, `docs/modules/router/`.
+
+## Dependencies & Concurrency
+- Depends on: `SPRINT_1200_001_001`, `SPRINT_1200_001_002`, `SPRINT_1200_001_003`.
+- Can run in parallel with Sprint 5 tests.
+
+## Documentation Prerequisites
+- `docs/README.md`
+- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
+- `docs/modules/platform/architecture-overview.md`
+- `docs/modules/router/architecture.md`

+
+## Decisions & Risks
+- **Decision:** Keep docs offline-friendly: no external CDNs/snippets; prefer deterministic, copy-pastable YAML fragments.
+- **Risk:** Confusion during rollout if both router and service rate limiting are enabled. Mitigation: explicit migration guide + recommended rollout phases.

+- Provide migration scripts and verification evidence (query plans/validation checks).
+- Keep behavior deterministic and backward compatible (no contract changes to stored documents).
+
+## Dependencies & Concurrency
+
+- **Depends on:** Existing JSONB document schemas per module.
+- **Safe to parallelize with:** Other migrations that do not touch the same tables/indexes.
+
+## Documentation Prerequisites
+
+- `docs/db/SPECIFICATION.md`
+- `docs/product-advisories/14-Dec-2025 - PostgreSQL Patterns Technical Reference.md`

+# Router · Rate Limiting
+
+This page is the module-level dossier for centralized rate limiting in the Router gateway (`StellaOps.Router.Gateway`).
+
+## What it is
+- A **gateway responsibility** that applies policy and protects both the Router process and upstream microservices.
+- Configurable by environment, microservice, and (for environment scope) by route.
+- Deterministic outputs and bounded metric cardinality by default.
+
+## How it works
+
+### Scopes
+- **for_instance**: in-memory sliding window counters (fast path).
+- **for_environment**: Valkey-backed fixed windows (distributed coordination).
+
+### Inheritance
+- Environment defaults → microservice override → route override.
+- Replacement semantics: a more-specific `rules` set replaces the parent rules.
+
+### Rule stacking
+- Multiple rules on a target are evaluated with AND logic.
+- Denials return the most restrictive `Retry-After` across violated rules.
+
+## Operational posture
+- Valkey failures are fail-open (availability over strict enforcement).
+- Activation gate reduces Valkey load at low traffic.
+- Circuit breaker prevents cascading latency when Valkey is degraded.
+
+## Migration notes (avoid double-limiting)
+- Prefer centralized enforcement at the Router; remove service-level HTTP limiters after Router limits are validated.
+- Roll out in phases (high limits → soft limits → production limits).
+- If a microservice must keep internal protection (e.g., expensive job submission), ensure it is semantically distinct from HTTP admission control and does not produce conflicting client UX.
+
+## Documents
+- Configuration guide: `docs/router/rate-limiting.md`
+- Per-route guide: `docs/router/rate-limiting-routes.md`
+- Ops runbook: `docs/operations/router-rate-limiting.md`
+- Testing: `tests/StellaOps.Router.Gateway.Tests/` and `tests/load/router-rate-limiting-load-test.js`

+# Router Rate Limiting Runbook
+
+Last updated: 2025-12-17
+
+## Purpose
+- Enforce centralized admission control at the Router (429 + Retry-After).
+- Reduce duplicate per-service HTTP throttling and standardize response semantics.
+- Keep the platform available under dependency failures (Valkey fail-open + circuit breaker).
+
+## Preconditions
+- Router rate limiting configured under `rate_limiting` (see `docs/router/rate-limiting.md`).
+- If `for_environment` is enabled:
+ - Valkey reachable from Router instances.
+ - Circuit breaker parameters reviewed for the environment.
+
+## Rollout plan (recommended)
+1. **Dry-run wiring**: enable rate limiting with limits set far above peak traffic to validate middleware order, headers, and metrics.
+2. **Soft limits**: set limits to ~2× peak traffic and monitor rejected rate and latency.
+3. **Production limits**: set limits to target SLO and operational constraints.
+4. **Migration cleanup**: remove any remaining service-level HTTP rate limiters to avoid double-limiting.
+
+## Monitoring
+
+### Key metrics (OpenTelemetry)
+- `stellaops.router.ratelimit.allowed{scope,microservice,route?}`
+- `stellaops.router.ratelimit.rejected{scope,microservice,route?}`
+- `stellaops.router.ratelimit.check_latency{scope}`
+- `stellaops.router.ratelimit.valkey.errors{error_type}`
+- `stellaops.router.ratelimit.circuit_breaker.trips{reason}`
+- `stellaops.router.ratelimit.instance.current`
+- `stellaops.router.ratelimit.environment.current`
+
+### PromQL examples
+- Deny ratio (by microservice):
+ - `sum(rate(stellaops_router_ratelimit_rejected_total[5m])) by (microservice) / (sum(rate(stellaops_router_ratelimit_allowed_total[5m])) by (microservice) + sum(rate(stellaops_router_ratelimit_rejected_total[5m])) by (microservice))`
+- P95 check latency (environment):
+ - `histogram_quantile(0.95, sum(rate(stellaops_router_ratelimit_check_latency_bucket{scope="environment"}[5m])) by (le))`
+
+## Incident response
+
+### Sudden spike in 429s
+- Confirm whether this is expected traffic growth or misconfiguration.
+- Identify the top offenders: `rejected` by `microservice` and (optionally) `route`.
+- If misconfigured: raise limits conservatively (2×), redeploy config, then tighten gradually.
+
+### Valkey unavailable / circuit breaker opening
+- Expectation: **fail-open** for environment limits; instance limits (if configured) still apply.
+- Check:
+ - `stellaops.router.ratelimit.valkey.errors`
+ - `stellaops.router.ratelimit.circuit_breaker.trips`
+- Actions:
+ - Restore Valkey connectivity/performance.
+ - Consider temporarily increasing `process_back_pressure_when_more_than_per_5min` to reduce Valkey load.
+
+## Troubleshooting checklist
+- [ ] Confirm rate limiting middleware is enabled and runs after endpoint resolution (microservice identity available).
+- [ ] Validate YAML binding: incorrect keys should fail fast at startup.
+- [ ] Confirm Valkey connectivity from Router nodes (if `for_environment` enabled).
+- [ ] Ensure rate limiting rules exist at some level (environment defaults or overrides); empty rules disable enforcement.
+- [ ] Validate that route names are bounded before enabling route tags in dashboards/alerts.
+
+## Load testing
+- Run `tests/load/router-rate-limiting-load-test.js` against a staging Router configured with known limits.
+- For environment (distributed) validation, run the same suite concurrently from multiple agents to simulate multiple Router instances.

+
+## Overview
+
+Per-route rate limiting lets you apply different limits to specific HTTP paths **within the same microservice**.
+
+Configuration is nested as:
+
+`rate_limiting.for_environment.microservices..routes.`
+
+## Configuration
+
+### Example (rules + routes)
+
+```yaml
+rate_limiting:
+ for_environment:
+ valkey_connection: "valkey.stellaops.local:6379"
+ valkey_bucket: "stella-router-rate-limit"
+
+ # Default environment rules (used when no microservice override exists)
+ rules:
+ - per_seconds: 60
+ max_requests: 600
+
+ microservices:
+ scanner:
+ # Default rules for the microservice (used when no route override exists)
+ rules:
+ - per_seconds: 60
+ max_requests: 600
+
+ routes:
+ scan_submit:
+ pattern: "/api/scans"
+ match_type: exact
+ rules:
+ - per_seconds: 10
+ max_requests: 50
+
+ scan_status:
+ pattern: "/api/scans/*"
+ match_type: prefix
+ rules:
+ - per_seconds: 1
+ max_requests: 100
+
+ scan_by_id:
+ pattern: "^/api/scans/[a-f0-9-]+$"
+ match_type: regex
+ rules:
+ - per_seconds: 1
+ max_requests: 50
+```
+
+### Match types
+
+`match_type` supports:
+
+- `exact`: exact path match (case-insensitive), ignoring a trailing `/`.
+- `prefix`: literal prefix match; patterns commonly end with `*` (e.g. `/api/scans/*`).
+- `regex`: regular expression (compiled at startup; invalid regex fails fast).
+
+### Specificity rules
+
+When multiple routes match a path, the most specific match wins:
+
+1. `exact`
+2. `prefix` (longest prefix wins)
+3. `regex` (longest pattern wins)
+
+## Inheritance (resolution)
+
+Rate limiting rules resolve with **replacement** semantics:
+
+- `routes..rules` replaces the microservice rules.
+- `microservices..rules` replaces the environment rules.
+- If a level provides no rules, the next-less-specific level applies.
+
+## Notes
+
+- Per-route rate limiting applies at the **environment** scope (Valkey-backed).
+- The Router returns `429 Too Many Requests` and a `Retry-After` header when a limit is exceeded.
+
+## See also
+
+- `docs/router/rate-limiting.md` (full configuration guide)

+# Router Rate Limiting
+
+Router rate limiting is a **gateway-owned** control plane feature implemented in `StellaOps.Router.Gateway`. It enforces limits centrally so microservices do not implement ad-hoc HTTP throttling.
+
+## Behavior
+
+When a request is denied the Router returns:
+- `429 Too Many Requests`
+- `Retry-After: `
+- `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset` (Unix seconds)
+- JSON body:
+
+```json
+{
+ "error": "rate_limit_exceeded",
+ "message": "Rate limit exceeded. Try again in 12 seconds.",
+ "retryAfter": 12,
+ "limit": 100,
+ "current": 101,
+ "window": 60,
+ "scope": "environment"
+}
+```
+
+## Model
+
+Two scopes exist:
+- **Instance (`for_instance`)**: in-memory sliding window; protects a single Router process.
+- **Environment (`for_environment`)**: Valkey-backed fixed window; protects the whole environment across Router instances.
+
+Environment checks are gated by an **activation threshold** (`process_back_pressure_when_more_than_per_5min`) to avoid unnecessary Valkey calls at low traffic.
+
+## Configuration
+
+Configuration is under the `rate_limiting` root.
+
+### Minimal (instance only)
+
+```yaml
+rate_limiting:
+ process_back_pressure_when_more_than_per_5min: 5000
+
+ for_instance:
+ rules:
+ - per_seconds: 60
+ max_requests: 600
+```
+
+### Environment (Valkey)
+
+```yaml
+rate_limiting:
+ process_back_pressure_when_more_than_per_5min: 0 # always check environment
+
+ for_environment:
+ valkey_connection: "valkey.stellaops.local:6379"
+ valkey_bucket: "stella-router-rate-limit"
+
+ circuit_breaker:
+ failure_threshold: 5
+ timeout_seconds: 30
+ half_open_timeout: 10
+
+ rules:
+ - per_seconds: 60
+ max_requests: 600
+```
+
+### Rule stacking (AND logic)
+
+Multiple rules on the same target are evaluated with **AND** semantics:
+
+```yaml
+rate_limiting:
+ for_environment:
+ rules:
+ - per_seconds: 1
+ max_requests: 10
+ - per_seconds: 3600
+ max_requests: 3000
+```
+
+If any rule is exceeded the request is denied. The Router returns the **most restrictive** `Retry-After` among violated rules.
+
+### Microservice overrides
+
+Overrides are **replacement**, not merge:
+
+```yaml
+rate_limiting:
+ for_environment:
+ rules:
+ - per_seconds: 60
+ max_requests: 600
+
+ microservices:
+ scanner:
+ rules:
+ - per_seconds: 10
+ max_requests: 50
+```
+
+### Route overrides
+
+Route-level configuration is under:
+
+`rate_limiting.for_environment.microservices..routes.`
+
+See `docs/router/rate-limiting-routes.md` for match types and specificity rules.
+
+## Notes
+
+- If `rules` is present, it takes precedence over legacy single-window keys (`per_seconds`, `max_requests`, `allow_*`).
+- For allowed requests, headers represent the **smallest window** rule for deterministic, low-cardinality output (not a full multi-rule snapshot).
+- If Valkey is unavailable, environment limiting is **fail-open** (instance limits still apply).
+
+## Testing
+
+- Unit tests: `dotnet test StellaOps.Router.slnx -c Release`
+- Valkey integration tests (Docker required): `STELLAOPS_INTEGRATION_TESTS=true dotnet test StellaOps.Router.slnx -c Release --filter FullyQualifiedName~ValkeyRateLimitStoreIntegrationTests`
+- k6 load tests: `tests/load/router-rate-limiting-load-test.js` (see `tests/load/README.md`)

+# StellaOps.Attestor.Persistence — Local Agent Charter
+
+## Scope
+- This charter applies to `src/Attestor/__Libraries/StellaOps.Attestor.Persistence/**`.
+
+## Primary roles
+- Backend engineer (C# / .NET 10, EF Core, Npgsql).
+- QA automation engineer (xUnit) for persistence + matcher logic.
+
+## Required reading (treat as read before edits)
+- `docs/modules/attestor/architecture.md`
+- `docs/db/SPECIFICATION.md`
+- `docs/db/MIGRATION_STRATEGY.md`
+- PostgreSQL 16 docs (arrays, indexes, JSONB, query plans).
+
+## Working agreements
+- Determinism is mandatory where hashes/IDs are produced; all timestamps are UTC.
+- Offline-friendly defaults: no network calls from library code paths.
+- Migrations must be idempotent and safe to re-run.
+- Prefer small, composable services with explicit interfaces (`I*`).
+
+## Testing expectations
+- Unit/integration tests live in `src/Attestor/__Tests/StellaOps.Attestor.Persistence.Tests`.
+- Perf dataset and query harness lives under `src/Attestor/__Libraries/StellaOps.Attestor.Persistence/Perf` and must be deterministic (fixed data, fixed sizes, documented parameters).

+# ProofChain DB perf harness
+
+This folder provides a deterministic, production-like dataset and a small harness to validate index/query performance for the ProofChain schema (`proofchain.*`).
+
+## Files
+- `seed.sql` – deterministic dataset generator (uses SQL functions + `generate_series`).
+- `queries.sql` – representative queries with `EXPLAIN (ANALYZE, BUFFERS)`.
+- `run-perf.ps1` – starts a local PostgreSQL 16 container, applies migrations, seeds data, runs queries, and captures output.
+
+## Run
+From repo root:
+
+```powershell
+pwsh -File src/Attestor/__Libraries/StellaOps.Attestor.Persistence/Perf/run-perf.ps1
+```
+
+Output is written to `docs/db/reports/proofchain-schema-perf-2025-12-17.md`.

+- Determinism requirements:
+ - All manifest entries and tarball paths must be sorted deterministically (ordinal string compare).
+ - Hash inputs must be canonical and stable; retrying packaging MUST yield identical bundle bytes when inputs are unchanged.
+- Local evidence cache (offline-first, side-by-side with scan artefacts):
+ - `src/ExportCenter/StellaOps.ExportCenter/StellaOps.ExportCenter.Core/EvidenceCache/LocalEvidenceCacheService.cs`
+ - Cache manifests and enrichment queue must be deterministic and replay-safe.
## Working Agreements
- Enforce tenant scoping and RBAC on every API, worker fetch, and distribution path; no cross-tenant exports unless explicitly whitelisted and logged.

+- Decision domain model lives under `src/Findings/StellaOps.Findings.Ledger/Domain/DecisionModels.cs`.
+- Decision invariants:
+ - Decisions are append-only (corrections are new events).
+ - Every decision MUST include a `replay_token` (content-addressed reproduce key).
+ - Evidence hashes captured at decision time must be stable and ordered deterministically.
## Execution rules
- Update sprint `Delivery Tracker` status when you start/stop/finish: TODO → DOING → DONE/BLOCKED.
