File history: follow renamed and rewritten files; absent version at the right commit - #95

FRM-05 is now a GWT acceptance scenario: given Git Good was just opened, when the folder is not a Git repository and not inside one, then it opens on the welcome view. The Reopen the last repository preference, which opened the most recent repository instead and was on by default, is removed with its launch fallback; an old "reopen_last" key in settings.json is ignored. FRM-06 covers a launch in a repository's subfolder, which opens that repository.

Reported on baol/recipes: after renaming Focaccia.md, Review of the rename commit listed the old path as deleted and the new one as added with every line new, so the file's history looked cut at the rename. Review now pairs renames as git diff -M does (exact moves and moves with edits, 50 % similarity), with gix's tree diff in process, read only when a comparison adds or deletes a file. A rename is one change at the new path with the old side and old_path/old_path_bytes, marked R in the file list; File history on it crosses the rename. The CLI's show lists kind "renamed" with old_path, and --file accepts either path.

Reported on baol/recipes: File history of "Focaccia con il Bimby.md" stopped at 935e221, where Focaccia.md was renamed and mostly rewritten (27 % alike, below Git's 50 % rename threshold; git log --follow stops there too). The earlier rename fix was checked on a pure git mv only. An added file now continues the most similar file the same commit deleted, down to 25 % similarity (RENAME_SIMILARITY_PERCENT), in File history (git diff-tree -M25%) and in Review (gix rewrites at 0.25). Acceptance REV-78; its four tests fail at 50 % and pass at 25 %. On the recipes clone File history now lists 7 versions across the rename.

File history of baol/recipes' Focaccia ended with an absent row at the repository's first commit (6f2795d Initial commit) instead of the commit just before the file was added (d46c131 Update pancakes., parent of d7fb0bb): an absent state took the commit where the absence began. Before a file first appears its absent version is now the commit just before the add; after a deletion it stays the deleting commit. Acceptance REV-79; its tests fail without the change.

Two File history fixes from
baol/recipes, each reproduced on that repository before the change and validated on it after.1. Follow a renamed and rewritten file down to 25 % similarity
File history of
docs/Pane e pizza/Focaccia con il Bimby.mdshowed 2 rows. In 935e221 the file was renamed fromFocaccia.mdand mostly rewritten (27 % alike). That is below Git's 50 % threshold, so evengit log --followstops there. The earlier fix (#93) had only been checked on a puregit mv.Decision (user): an added file continues the most similar file the same commit deleted, down to 25 %. One constant,
RENAME_SIMILARITY_PERCENT, drives both File history (git diff-tree -M25%) and Review (gix rewrites at 0.25).Validated on the clone: File history lists 7 versions, from

R030.2. The absent version names the commit just before the file
The absent row at the end of File history read
6f2795d Initial commit, the repository's first commit. It should name the commit just before the file was added:d46c131 Update pancakes., the parent of d7fb0bb. An absent state took the commit where the absence began.It now takes the commit just before the add. After a deletion, it stays the commit that deleted the file.

Checks
fmt, clippy
-D warnings, all workspace tests, and the README screenshot--checkpass. The branch also carries a no-op merge of the old #93 tip, so it could be pushed without force.🤖 Generated with Claude Code
