[architect] Spec duplication across deps/, gnome-49/, gnome-50/ — overlapping packages with no inheritance

Architecture Finding

Type: coupling / tech-debt
Affected area: src/deps/, src/gnome-49/, src/gnome-50/

Same packages (avahi, fontconfig, gtk4, mutter, glib2, etc.) are defined in 2-3 different directories, each with independent spec file copies:

• src/deps/ — 42 dependency packages
• src/gnome-49/ — GNOME 49 variants
• src/gnome-50/ — GNOME 50 variants

Impact

• Bug fixes to a shared package must be manually propagated across 2-3 directories
• 3x maintenance cost for shared packages
• No inheritance or patch-overlay mechanism

Recommendation

Consolidate into single source tree with variant patches. Define base spec + version-specific deltas (Fedora dist-git model).
