Add unit tests for Router configuration and transport layers

- Implemented tests for RouterConfig, RoutingOptions, StaticInstanceConfig, and RouterConfigOptions to ensure default values are set correctly.
- Added tests for RouterConfigProvider to validate configurations and ensure defaults are returned when no file is specified.
- Created tests for ConfigValidationResult to check success and error scenarios.
- Developed tests for ServiceCollectionExtensions to verify service registration for RouterConfig.
- Introduced UdpTransportTests to validate serialization, connection, request-response, and error handling in UDP transport.
- Added scripts for signing authority gaps and hashing DevPortal SDK snippets.

+# Excititor OpenAPI Freeze Checklist (chunk API) — unblocker for EXCITITOR-DOCS-0001
+
+Status: awaiting CI validation + contract freeze. This checklist defines the gate to flip EXCITITOR-DOCS-0001 to DOING/DONE.
+
+## Freeze criteria
+- Chunk API CI green on main (tests + contract lint).
+- OpenAPI spec version pinned (e.g., `api/chunk-api.yaml` with semver tag) and referenced from README/architecture.
+- Breaking-change log reviewed (added/removed fields, status codes) with ack from Console Guild.
+- Deterministic samples produced (request/response NDJSON) and hash-listed.
+- Observability fields (trace IDs, request IDs) documented.
+
+## Required artefacts
+- `docs/modules/excititor/api/chunk-api.yaml` (pinned version)
+- `docs/modules/excititor/api/SHA256SUMS` with hashes for OpenAPI + samples (file stub present)
+- `docs/modules/excititor/api/samples/*.json` (deterministic examples; directory stub present)
+
+## Actions when criteria met
+1) Set EXCITITOR-DOCS-0001 to DOING in sprint and TASKS; pull pinned OpenAPI + samples.
+2) Update module README/architecture to reference the pinned spec + samples.
+3) Add hash entries to `docs/modules/excititor/api/SHA256SUMS`.
+4) Flip EXCITITOR-DOCS-0001 to DONE and unblock ENG/OPS tasks.

+## Latest updates (2025-12-05)
+- OpenAPI freeze gate added at `OPENAPI_FREEZE_CHECKLIST.md`; EXCITITOR-DOCS-0001 remains BLOCKED until chunk API CI passes and pinned spec + hashed samples are delivered.

 - Observability/runbook assets remain in `operations/observability.md` and `observability/` (timeline, locker manifests); dashboards stay offline-import friendly.
 - Prior updates (2025-11-05): Link-Not-Merge readiness and consensus beta note (`../../updates/2025-11-05-excitor-consensus-beta.md`), observability guide additions, DSSE packaging guidance, and Policy/CLI follow-ups tracked in SPRINT_200.
 - Link-Not-Merge readiness: release note [Excitor consensus beta](../../updates/2025-11-05-excitor-consensus-beta.md) captures how Excititor feeds power the Excititor consensus beta (sample payload in [consensus JSON](../../vex/consensus-json.md)).
