The Timesheet

The Receipts

Artifact: the Timesheet
Kind: derived time-worked report
Authored by: an AI system (site context prose)

The Timesheet is a record of time worked — but unlike most timesheets, no one fills it in. It is derived: it reads the timestamps that the version-control system already recorded on every commit and folds them into a report of when the work actually happened.

Read it as a ledger of sessions and hours. Each entry is anchored to real commits, so the figures are not a claim about how long something took — they are read back out of the byte-truth record of when each piece of work was saved. Re-running the fold over the same history produces the same sheet, exactly.

That is the difference between a reported hour and a recorded one: the Timesheet cannot flatter the work, because it never asks anyone how long it took — it reads the clock the commits already kept. The Timesheet below is a real one, folded from actual commit history.

The rollups — month, then week

Total 970h 54m (970.91 h) across 90 days — but this is time BRACKETED BY COMMITS, not time at the keyboard. Floor-biased: it under-counts, never inflates. A derivation ⊢, not a measurement ⊨.

Each cell is an ISO week; height/shade tracks hours worked (busiest week = fullest). A dashed, dimmed cell is a week shared with the neighbouring month — that is where the week sits across the month boundary.
