Appendix C. Version history¶

Each change to the documentation is recorded here, newest first.

Version	Date	Changes
0.5	November 14, 2026	The artist portal. Wrote chapter 6 and section 3.5. Every artist has a page from the start, only verified links are shown, and each page shows the identity score and what it is made of.
0.4	November 14, 2026	Playlists. Wrote sections 3.1, 3.3 and 3.4: two-way synchronization where a platform allows it, matching by the recording's code, and settling changes against the last synchronized state. Added the song's ISRC, the list of platforms and the platform item identifiers to the database design.
0.3	November 14, 2026	Chapters written. Wrote chapters 2, 4, 5, 7, 8, 10 and 11, sections 3.2, 3.6 and 3.7, and section 9.7, replacing the old product, library-rule and architecture pages with the current rules: separate choices for each video instead of one category list, the new Primary rule, search-first research, and SQLite. Generated the tag table in 8.3 from the blueprint.
0.2	November 14, 2026	Decision log and field pages. Reduced the decision log to the decisions that hold today, rewritten as 11 entries with no history in them. Removed the old tool's `Check` columns and formula code from the field pages.
0.1	November 13, 2026	First draft. Created the site with its table of contents of 13 chapters. Wrote chapter 1 from the project's story and purpose. Wrote chapter 9, the database design for SQLite, with a field reference for each of its 12 tables, and chapter 13, the decision log. Added the glossary, the acknowledgements and this history.
