+
+### Glaztech — Exchange Online DMARC Override
+
+- Consented Exchange Operator app in glaztech.com tenant (82931e3c-de7a-4f74-87f7-fe714be1f160)
+- Created transport rule "TEMP - Allow DMARC fail from clearcutglass.com" via EXO REST InvokeCommand
+  - GUID: 6b702a5c-02ad-46e5-a2e1-7cb70284bd5c
+  - Action: SetSCL = -1 for sender domain clearcutglass.com
+- Syncro ticket #32176 created for Glaz-Tech Industries (customer ID 143932)
+- Full detail: `clients/glaztech/session-logs/2026-04-20-session.md`
+
+### Syncro Skill Fix
+
+- Investigated why labor/time entries weren't being saved on tickets
+- Root cause: `POST /tickets/{id}/comment` silently ignores `product_id`, `minutes_spent`, `bill_time_now` (Syncro API bug)
+- Fix: use `POST /tickets/{id}/timer_entry` with `start_at`, `end_at`, `billable`, `product_id` — confirmed working
+- Updated `.claude/commands/syncro.md` with correct two-call pattern and WARNING on broken comment fields
+- New behavior rules: always ask for minutes + labor type before billing; always show comment preview before posting
+
+### Memory Updates
+
+- `feedback_syncro_billing.md` — ask for time + show preview before any Syncro billing action
