The three /api/diagnostics/* routes (export, preview, hardware) plus their
exclusive payload-cap helpers and the `_diag_*` normalisers. Bodies verbatim
except @app->@router, CONFIG_DIR->appstate.config_dir, _running_version()->
appstate.running_version() (a new seam slot; the impl stays in server.py where
the settings region also calls it), and the builtin-plugins lookup in
_diag_plugins_roots: Path(__file__).parent -> Path(__file__).resolve().parents[2]
(routers -> lib -> app root; plugins/ ships at the app root in every packaging
path).
The pure caps/normalisers (_diag_cap_console/_dict/_contributions,
_diag_coerce_bool, _diag_normalize_include, _DIAG_MAX_*) are re-exported from
server.py so the existing `server._diag_*` / `server._DIAG_*` tests keep
resolving — none of them monkeypatch these, so no test retargets.
server.py: 7,216 -> 6,960.
Verified: pyflakes clean (bar the intentional re-export lines); route table
IDENTICAL (143); full pytest 2399 passed (77 diag/packaging + 122 diagnostic-
matched cases incl the cap/coerce/normalize suites); eslint 0; Codex pending.
Boot smoke: /hardware, /preview, and POST /export (200 application/zip) all
serve from the new router location.
