"""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
  6. instructions    CLAUDE.md length/versions/TEMPORARY, rule-file scoping, workspace-copy identity
  7. golden-currency a released controller has a golden carrying it (R-242)
  8. wire-contract   every emitted field is decodable by its receiver (G-1)
  9. hub-copy        the hub's customer-facing words, against the retired-name list (R-324)
 10. due-checks      a dated check in OPEN-ITEMS.md that has come due (R-341)
 11. one-register    open work living outside OPEN-ITEMS.md (R-369)
 12. closed-register a CLOSED row whose verdict still reads open, or an id in both (R-405)
 13. observations    a REPORT.md observation with no register row behind it (R-389)

**THE `GATES` TABLE BELOW IS THE LIST; THIS IS A POINTER TO IT.** It drifted once already —
it read eleven while thirteen were registered, from 2026-08-24 until 2026-09-01, so
`one-register` and `closed-register` ran on every push while being documented nowhere
(R-418). Add a gate here in the same commit, or delete this list rather than let it lie.

SCOPE (R-404, 2026-09-01). `--scope=docs` marks a push whose whole range touches documents.
It changes ONE thing: a CONVICTION by a gate whose fifth `exemptible` field is True — today
`golden-currency`, and only it — prints as ADVISORY and does not refuse the push. The gate
still RUNS and still CONVICTS; its verdict, exit codes and wording are untouched. Every
other gate refuses every push, in every scope. An unscoped run behaves exactly as before.

WHY 11 IS HERE (2026-08-24, R-389). On 2026-08-23 a session measured on live hardware that only the
FIRST broken app per hour reaches the operator — the notification cooldown keys on the event type,
not on the app. It was real, reproducible, and written under `## Observations` in `REPORT.md`. It was
written NOWHERE ELSE. `REPORT.md` is overwritten every session by this project's own convention, so
the finding had a lifetime of exactly one session and had to be re-derived the next day. That is
gate 10's shape one surface over — a commitment recorded in prose that nothing enforces — and the
instruction invited it: PROMPT-TEMPLATE.md §15 asked for observations "documented, not acted on", and
"documented" was satisfied by the paragraph. The template was corrected in the same session; **this
gate is the mechanism that correction points at.** It REFUSES rather than warns, for gate 10's
reason. It PASSES quietly when there is no observations section, deliberately — a gate that taxes
every push is one that gets disabled within a week. `--fast` (stdlib file reads only).

WHY 10 IS HERE (2026-08-18, R-341). R-341 booked two dated measurements — +24 h and +7 d —
as a sentence inside a register row. Nothing read those dates, and nothing would have said a word
when they passed; the row would simply have gone quiet and stayed that way. That is the same shape
as R-242 (a rule filed without a mechanism, which recurred the next day) and as the R-29 census
finding below, where the checks nobody was told to run were the ones that had been failing for
weeks. The dates now live in a machine-readable block INSIDE OPEN-ITEMS.md — inside, so there is no
sidecar to drift from the register — and this gate refuses the push once one comes due. It REFUSES
rather than warns, deliberately: a warning is the thing that gets scrolled past, and this repo has
the census to prove it. It is `--fast` (stdlib file read, no network) so it runs in both the
pre-push hook and CI. **It is not a scheduler and its docstring says so** — it fires on the next
push after a date passes, not on the date.

WHY 7 IS HERE (2026-08-08, R-242). R-242 was filed as a rule with no mechanism — *a controller
release is not finished until a golden carries it* — and RECURRED THE NEXT DAY: v0.206.0 shipped
while the vouched golden still carried 0.205.0, so a machine installed that morning would have got
neither of the R-241 fixes. Two occurrences in two days, the first (R-239) invisible until a walk
measured it from the customer's side. It is `--fast` because both the pre-push hook and CI run only
`--fast`; a non-fast gate would run in neither, which is the R-29 failure this runner ended. That
constraint is why it checks the BAKE and not the vouch — the full reasoning is in its docstring.

WHY 6 IS HERE AND WAS NOT (2026-08-06, R-229 deferred leg). instructions_gate.py LIVES in this
repo's scripts/ and was registered in the controller and agent runners on the day it was written —
but not in this one, because this repo's own CLAUDE.md was still 27 lines over the ceiling and a
registered-but-failing gate refuses every push through .githooks/pre-push. The file was trimmed
(227 -> 115 effective lines, core + .claude/rules/) and the gate registered in the same session.
A check that does not run in the place it applies is the exact failure the R-29 gate census found.

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.
