Laborbuch — user manual

Logging in, the dashboard, entries field by field, limits, commits, reports and week closes.

The day-to-day manual for Laborbuch — for everyone who keeps records. System configuration is covered by the separate administrator manual.

Logging in

Open your instance’s address, then the Journal (/dashboard/). The login form has three fields: User, Password and One-time code (2FA).

The dashboard — what you see after logging in

A new entry — field by field

Field What to enter
Project The project the work belongs to (you only see your projects)
Vorhaben The undertaking code from the BSFZ application (e.g. B5) — your R&D lead knows it
Work date The day the work happened (not the day of typing it in)
Hours Working time, e.g. 2 or 2.5
From / To Optional time range — strengthens credibility
off-computer Tick for conceptual/paper work — a switched-off computer then disproves nothing
outside R&D (continuity/routine) Tick when the work is NOT research (maintenance, routine) — the entry documents continuity but its hours do not count towards R&D totals, the weekly cap or reports
Activity (R&D core) What exactly you did — the auditor will read this sentence; be factual
Result / note Close the block with one result sentence: a decision, a rejected alternative, a conclusion
Commits (evidence anchors) Tick the commits the entry covers — the list narrows after choosing a project; commits not yet described are marked “no entry”
Evidence files Scans, instrument printouts, photos, measurement data; in hash-only mode the file is not uploaded — the browser computes only its SHA-256 fingerprint

Click Save entry. It appears immediately under “Recent entries”.

Rules the system enforces

Made a mistake — what now

Commits — where they come from and why

Commits of the project repositories are fetched automatically every 15 minutes (Refresh commits forces it immediately). A commit attached to an entry becomes an evidence anchor. The commit table has an Entry column: ✓ means “described”, highlighted no entry is your to-do list. Describe routine commits too — with “outside R&D” ticked.

Reports

Menu: Auditor report (Stundenaufzeichnung — entries by week, with close status) and BSFZ basis (activities grouped by project and Vorhaben).

Week closes

The administrator closes the week. Closing computes the cryptographic fingerprint (SHA-256) of all the week’s entries and timestamps it through two independent channels. From then on entries carry 🔒 and the Week closes table shows status and fingerprint. For you it means one thing: record as you go — nothing can be added after the close.
