Leave Calendar Compatibility API

Summary

Six compatibility operations expose Holiday CRUD and weekly-off read/replace using existing client routes.

Audience

Frontend/backend developers, QA, Leave/Attendance administrators, support, and implementation partners.

Reference Content

Maturity: Compatibility / Transitional. Authentication: monolith requires authenticated calls; gateway/service expectation applies after cutover. Authorization: monolith permits authenticated reads and administrator mutations; extracted parity Requires confirmation. Tenant: required.

Operation	Method/public route	Body/parameters	Response/status	Behavior
List Holidays	GET /api/holidays	None	200 Holiday rows	Tenant list; no filter/side effect.
Create Holiday	POST /api/holidays	Holiday name/date/type	200 row; 400 invalid; 403 monolith non-admin	Audit in extracted service; no Leave event.
Update Holiday	PUT /api/holidays/{id}	Route id + Holiday body	200 row; 404; 400/403 as owner enforces	Replaces fields.
Delete Holiday	DELETE /api/holidays/{id}	Route id	200 plain success; 404; possible 403	Removes entry.
List weekly offs	GET /api/weekly-offs	None	200 day rows	Read-only.
Replace weekly offs	PUT /api/weekly-offs	JSON day-name array	200 day rows; possible 400/403	Replaces tenant collection; exact day validation absent in extracted command.

Holiday fields and examples are in Holidays; weekly-off fields/examples are in Weekly Offs. No date-range Holiday lookup, optional/regional calendar operation, per-employee weekly-off operation, or individual weekly-off CRUD exists.

Weekly-off routing can resolve to Attendance Service before Leave Service depending on current Time Office ownership. This overlap is Transitional and must be included in gateway parity testing.
