PR_26175_CHARLIE_012-024-system-health-completion

[ToolboxAid]

Summary

• Extends the existing Charlie System Health stack from Phase 2 through completion commit 024.
• Keeps System Health scoped to the current deployment only; Environment Map remains reference-only.
• Adds runtime health, service health, configuration summary, manual actions, scheduled monitoring foundation, notifications foundation, API contract cleanup, environment capabilities, Admin API registry, runtime feature flags, focused contract tests, documentation closeout, and durable operational docs.
• Uses API/service contracts for health state; no browser-owned infrastructure health state or cross-environment checks.

System Health v1 Review Closeout

• PASS: System Health v1 is feature-complete through PR_26175_CHARLIE_024-system-health-operational-docs.
• PASS: Each deployment actively checks only itself; Environment Map remains reference-only.
• PASS: Local, DEV, IST, UAT, and PRD environment models are documented and covered by the API contract/test guardrails.
• PASS: Shared R2 folder model is documented as /local, /dev, /ist, /uat, and /prd.
• PASS: Manual health actions are API/service-contract owned.
• PASS: Scheduled monitoring and notifications remain production-safe Not Configured foundations.
• Future enhancements only: scheduler implementation, notification sending, deeper provider telemetry, external alert delivery, and any additional operational automation.
• No new Team Charlie System Health feature PRs should be opened unless Owner creates a new phase.
