From 686f5fb33ee13b9ce7c16518cf98acf5016f6ff3 Mon Sep 17 00:00:00 2001 From: saravanakumardb1 Date: Tue, 31 Mar 2026 23:31:04 -0700 Subject: [PATCH] =?UTF-8?q?feat(mcp):=20Phase=20A.1=20=E2=80=94=20reschedu?= =?UTF-8?q?le,=20availability,=20and=20start-routine=20endpoints?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add 3 new backend REST endpoints for MCP tool support: - POST /timers/:id/reschedule — shift timer by delta seconds or set new target time - GET /timers/availability — find free time slots in a window (interval merge algorithm) - POST /routines/:id/start — transition routine from ready/template → active All endpoints gated behind isFeatureEnabled('mcp.enabled') flag (default false). Zod schemas: RescheduleTimerSchema (XOR validation), AvailabilityQuerySchema, FreeSlot type. All 182 backend tests pass.
