admin 560f0d4451 G-1: a gate for the dropped field — built first, and seen failing on 40
Campaign 12 ranked this first of eight gating candidates. It is built BEFORE the fixes it finds,
because last night an off-the-shelf tool for a neighbouring class (deadcode, for C6) was made to
prove itself first and found NEITHER of the two defects it was meant for. A gate nobody has watched
fail has not been shown to work.

scripts/wire_contract_gate.py, registered in repo_gates.py as --fast (no network, no container, so
it runs in BOTH the pre-push hook and CI — the R-29 constraint).

THE TEST. For every json tag reachable from a declared wire ROOT, does that literal tag occur
anywhere in the receiving repo's production Go or templates? A tag occurring nowhere cannot be
decoded by any struct, named OR anonymous. That last clause is why a string test is used instead of
comparing struct to struct: Campaign 12's first attempt paired types by shape and false-positived
badly, because the hub decodes one report through several ad-hoc anonymous structs.

RESULT ON TODAY'S TREE: 210 tags checked across 3 declared wires, 51 skipped (generic / opaque /
allowlisted), 40 CONVICTED. Captured verbatim in documentation/tests/wire-contract-gate-2026-08-08/
BEFORE.md, which is deliverable 1 of this session.

The prompt for this session said "465 emitted tags, eight unreachable". Checked against the repo
rather than quoted: R-260's wording was "at least eight DECISION-BEARING facts", not eight tags in
total. The real count on the three declared wires is 40, and R-260's own census already listed more
than eight. Recorded because this prompt's own rule 6 says not to quote a document as source.

TWO THINGS THE CONTROL CAUGHT, both before the gate was trusted:

1. A SUBSTRING FALSE NEGATIVE. `grep -F healed_at` also matches `privsep_healed_at`, so a genuinely
   dropped field read as received — and R-260 named healed_at, so its absence from the output was
   the tell. Now a whole-token regex; healed_at is convicted.
2. dr_recipe IS NOT WHOLLY OPAQUE. The hub stores each half as json.RawMessage and re-emits nested
   shapes verbatim, so the LEAVES are genuinely not on this wire. But the TOP-LEVEL SECTION KEYS are
   decoded by hostHalfShape/appHalfShape, and those are ALLOW-LISTS: a section an emitter adds is
   silently dropped until named in both. That already cost `offsite_restic` (R-122). So the gate is
   opaque BELOW depth 1, not opaque — the sections are checked and pass.

Self-test: `--selftest` plants an unreachable tag on a real root in a throwaway copy and asserts
conviction. Verified: exit 1, planted tag named.

Blind spots are in the module docstring AND in the gate's own output, because Campaign 12's C1 guard
turned out blind to one of the three shapes it was written for: generic tag names are not checked;
reachability of a NAME is not use of a VALUE; only declared ROOTS are covered, and the hub's
desired-state (served as raw stored JSON, no typed emitter) and the agent local API are NOT.

Allowlist entries carry a stated reason. A quiet exclusion is a dropped field with paperwork.

Not pushed alone: the fixes follow in the next commit so main is never red on this check.

"""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)
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.
