jobcan:backfill

Month-end catch-up. Nothing is assumed about how the user works: the preset says which sources count as evidence of what they did and what their usual day looks like.

Needs

• The jobcan MCP server with writes enabled.
• The user's preset at ~/.config/jobcan-agent/preset.md, in particular its "My defaults" and "Backfill" sections. Missing preset: stop and ask for the usual hours, the attendance note and which sources to check, then suggest saving them as a preset.
• Whatever connectors the preset's sources need. A missing connector means that source is skipped, and the report says so.

Procedure

1. Pick the month. "Last month" is relative to jobcan_get_today. Confirm the month in one line if the user was vague.
2. Gather, read-only.
   • Jobcan: jobcan_get_timesheet for the month and jobcan_list_leave_requests for it.
   • Each source the preset lists (references/sources.md): the user's own posts in the channel for the month, out-of-office events on the calendar. Ignore other people's posts and events that are not about the user's absence.
3. Build the month, one row per workday, from the timesheet's own calendar (weekends and holidays are already marked there). For each day: what Jobcan has (leave, clock times, pending), what each source says (off, half day, hours, nothing).
4. Sort the days into:
   • agree: nothing to do;
   • leave missing in Jobcan: a source says off and Jobcan has no request;
   • unclear: sources disagree, a half day whose hours are not stated, an event that may not be leave (a lunch block, a trip), leave in the middle of a day;
   • nothing recorded: a workday with no leave and no clock times, to be filled in step 6. Show the table. Ask about every unclear day before going on; never resolve one by guessing. A source alone never proves leave: if the user says the calendar block was not leave, it is not leave.
5. File the missing leave: jobcan_request_leave for the confirmed dates, past dates allowed, the user's half-day rule from the preset for half days. One preview with the balance before and after, one yes, then confirm: true. Stop on any failure and report it.
6. Fill in the attendance: jobcan_record_attendance for the month with the preset's usual hours, note and spot. It skips days off, days already recorded, days on full-day leave and today, and works around hourly leave. Show its day-by-day plan (before → after), get one yes, then confirm: true.
7. Report: what was filed, what was recorded, what was skipped and why, and what still needs the user or an administrator (an approved request that is wrong, a day that could not be recorded).

Rules

• Leave before attendance, always: the attendance plan depends on the leave being in Jobcan.
• Two confirmations, one per step. Do not merge them; the user may want the leave but not the attendance.
• Never record attendance for a day the user has not accounted for if a source says they were away that day; that day goes to "unclear".
• Do not post anything to the channel or the calendar in this skill. If the reconciliation shows a leave that was filed but never announced, say so and offer jobcan:request-leave's announcement step separately.
• Jobcan is the source of truth for the result; the chat and calendar are evidence of intent.
