From PR #329 (stacked on #328): a game's usage manifest, dm/games/<id>/usage.tsv,
written by its owner with regress.py usage (shader features of its chain build,
and the NVN / HLE functions, SVCs and present path of one smoke-route run;
names and counts only), and regress.py impact <base>..<head>, which maps the
functions around the changed lines through the host's callers and the rules of
dm/tools/impact_map.tsv to manifest rows. Manifests for Breath of the Wild,
Tears of the Kingdom and Hades.
Fixed on top of the PR:
- impact checked the head out as a git worktree under the harness root, so it
stopped (PermissionError on /Volumes/NX) for exactly the contributors it is
for, who have no games and no harness root. The call graph is now read from
the git object store at the head revision, and the report is printed and
written only to --out or an existing harness root.
- A hunk mapped only to the function at its first line: a hunk spanning two
functions named one. Every added line is mapped now, and a pure deletion maps
to the function around it (it was moved one line up).
- Functions defined in headers were not in the call graph: the frame step
(nvn_fstep.h, static inline, called from nvnQueuePresentTexture) reached no
entry point, so 4acde72 named no game. Headers are scanned, and their
functions are visible to every file. 4acde72 now names both Zeldas through
nvnQueuePresentTexture.

Compare revision shader builds and pipeline interfaces across local games,
and run available smoke routes with crash, hang, timing and image checks.
Add the developer loop and share the measuring lock with bench.py.
Keep all local games in static checks and honor --no-smoke. Include shader
bytes and fallback pairs in cache keys, recheck interfaces on reuse, and
reuse smoke baselines only for matching inputs and run settings. Detect
failed prebuilds, missing or intermittently bad screenshots, and Vulkan
build failures even when no MSL was emitted. Keep game-derived files and
writable profile copies inside each game's NSP work folder.
Validation: tool tests and the lint ratchet pass. Full shader rebuilds and
gameplay comparisons remain unverified; the 26 discovered Mac builds have
no smoke routes in this checkout.
