"""repo_gates.py — THE entry point for this repo's gates. Run from the repo root:

    python3 scripts/repo_gates.py            # every gate
    python3 scripts/repo_gates.py --fast     # only gates that touch no network and no container
                                             # runtime (what .githooks/pre-push runs)

Gates, in order (all must pass; **non-zero exit on any failure**):

  1. site            website HTML: BOM, emoji, nav/footer, analytics, CDN, tokens, cache-busting
  2. hostinstall     felhom-host-install.sh's five drill-swept invariants (+ R-94's absent-version)
  3. hub-confirm     no native confirm()/prompt() in hub templates
  4. manifest-bearer no bearer-shaped literal anywhere in manifests/
  5. reuse-refs      every path cited by this repo's REUSE.md still resolves

WHY THIS FILE EXISTS (2026-08-02, closing R-29 leg (a) and half of leg (b)).

A census of all thirteen gate scripts across the four felhom repos found one clean correlation:
**every check a CLAUDE.md tells a person to run was passing, and two of the four nobody is told
to run were failing** — one since 14 July. Neither failure was harmful in effect, which was
checked line by line; nothing would have said so if they had been. The fix is not more gates, it
is one place to run them from. `app-catalog-felhom.eu/scripts/catalog_gates.py` is the canonical
shape (R-161) and this copies it deliberately rather than inventing a second one.

`site_gates.py` is a GATE — eight assertions in one file — and is NOT the model for this file. A
runner that invokes separate gates is the shape that survives; copying site_gates would just add
a ninth monolith.

FAIL-CLOSED. A gate script that is missing is a FAILURE, never a skip, and the exact path tried
is printed. A runner that quietly drops a gate is the inert-seam failure this project has shipped
four times.

EXIT CODES. Each gate returns 0 clean / 1 convicted / 2 inconclusive. This runner exits non-zero
if any gate is non-zero, and reports 2 distinctly as INCONCLUSIVE — an undetermined result is
never a pass, but it is not a conviction either, and the operator needs to know which they have.
