The last of the progression cluster. XP award (1 route) + per-song practice stats
(record/recent/best/top/per-song, 5 routes) — meta_db-only apart from the two
seam accessors record_stats uses (get_progression_content, builtin_diagnostic_
filename, both landed by shop/progression). Bodies verbatim; @app -> @router,
meta_db -> appstate.meta_db, _as_int from metadata_db, _clean_str from reqfields.
Three scattered source blocks (xp, the stats block, and the separated
/api/stats/{filename:path} which the /api/library/practice-suggestions route
splits off) are assembled into one module and mounted once. Registration order
is preserved WHERE IT MATTERS: the /api/stats/{filename:path} catch-all is
assembled LAST inside the router, so it still can't shadow the fixed /recent
/best /top paths — verified against the live route table (recent/best/top all
precede the catch-all) and the route SET is identical to origin/main (143).
server.py: 7,478 -> 7,275.
Verified: pyflakes clean; route set identical + catch-all-last; pytest 2401
passed (113 across song_stats/profile/progression); eslint 0. Boot smoke:
/stats/recent /best /top all 200 (not shadowed), xp/award 200.
