Conformance

sample-logbook/ is one week of a fictional person (Oslo, March 2026). Nothing in it is real.

Your implementation is conformant with format v0.1 when:

1. verify on sample-logbook/ reports valid and prints the seq and head in expected.json;
2. appending one line to a copy of it yields a logbook that still verifies, with seq + 1;
3. editing any byte inside any line's content, or deleting any line, makes verify fail.

Regenerate with python conformance/make_sample.py (only when the spec changes; it changes the head).
