fix(hooks): derive project wing from non-macOS transcript paths (#1145)

igorls · igorls · commit d1583750e8d9 · 2026-04-23T23:39:23.000-03:00
_wing_from_transcript_path only matched '-Projects-<name>' segments, so Linux users with code under ~/dev/, ~/code/, or ~/src/ fell through to the wing_sessions fallback and lost the per-project diary scoping introduced in #659. Broaden the heuristic to derive the project from the final dash-separated token of the encoded project-folder name under .claude/projects/. Keeps the legacy -Projects- regex as a secondary match for transcripts living outside the standard Claude Code path. Covers macOS Users layout, Linux dev/code layouts, and deeper nested source paths while preserving existing Projects/ behavior.
