MIS logbook submit

Read references/workflow.md before doing real work.

Core rules

• Use local secrets for login, never ask for or echo credentials in chat.
• Prefer browser automation with Playwright.
• Write Kegiatan/Materi in natural Indonesian.
• Respect the approval-first flow when a pending draft exists.
• Keep the text under the form limit and avoid literal SELECT, INSERT, UPDATE, and DELETE because the page may reject them.
• Check for an existing row before creating a new one.
• Verify both the success state and the saved row after submit.
