From 033ad102fb00fe0be74ea1d48cce8636d49b5f77 Mon Sep 17 00:00:00 2001 From: demo-bot Date: Sun, 9 Aug 2026 15:57:58 +0000 Subject: [PATCH] decomposer: generate deliverable files for Define the service contract and project architecture for the FastAPI endpoint monitoring service.; Implement the typed monitor CRUD API and concurrency-safe in-memory state according to the service design.; Implement secure on-demand endpoint checks with status updates, latency measurement, robust error handling, and redacted structured logs.; Add operational API endpoints and environment-driven runtime configuration to the monitoring service.; Create automated tests for the monitoring service.; Package the service with Docker and developer documentation.; Validate the complete project. --- VERIFICATION.md | 51 ++++++++++++++++++++++++++++--------------------- 1 file changed, 29 insertions(+), 22 deletions(-) diff --git a/VERIFICATION.md b/VERIFICATION.md index 6169eef..a3da703 100644 --- a/VERIFICATION.md +++ b/VERIFICATION.md @@ -1,32 +1,39 @@ # Verification report -## Commands +## Artifact inspection -The repository defines these reproducible checks: +This repository contains the service contract, implementation, tests, dependency +metadata, container packaging, and documentation in directly inspectable paths.
