Who wrote which line of version 1

Lines kept from an earlier version keep their author; added lines belong to the version that added them. Kinds: the heuristic of the store (a wholly new line with ≥ 15 words → writing, otherwise editing) unless set on save.

1	Jens Allmer	v1 writing	A component publication of the Internet of Science: `FASTALenFilter` 0.2.0, an atom. Generated from the manifest and the class comment on 2026-10-26; the author completes it and saves new versions. Lines marked FILL IN are the author's.

14	Jens Allmer	v1 writing
15	Jens Allmer	v1 writing	- input `in`: `FASTA.Entry` — One FASTA record: { header: string (with leading ">"), seq: string (no whitespace) }.

17	Jens Allmer	v1 writing
18	Jens Allmer	v1 writing	`## Parameters`
19	Jens Allmer	v1 writing
20	Jens Allmer	v1 writing	- `minLen` (integer, default 1, min 1): Minimum length
21	Jens Allmer	v1 writing	- `maxLen` (integer, default -1, min 1, -1 = unlimited): Maximum length (-1: unlimited)

50	Jens Allmer	v1 writing
51	Jens Allmer	v1 writing	`Maturity 1 of 3 (ADR 0012); a reviewer raises it, the credits earn it. Maturity 2 needs a test or test-validation credit by a person who is not an author: independent tests (CONTRIBUTING rules 17, 21); from then on this publication must exist (rule components/publication).`

73	Jens Allmer	v1 writing
74	Jens Allmer	v1 writing	`## Results`
75	Jens Allmer	v1 writing
76	Jens Allmer	v1 writing	FILL IN: run the example workflow (`node bin/ios.js run-workflow src/workflows/examples/fasta-length-filter.workflow.json --artefacts <dir>`) on a registered dataset, open the result in the builder and drag the figure or table into this article (Manuscript pane); write one paragraph on what it shows.
