# The wire-contract gate, run against the tree at b7fb211 on 2026-08-08

Deliverable 1 of the G-1/R-260 session: the gate FAILING, before any field was fixed.
Captured verbatim. If this had been green, the gate would not work and that would be the finding.

WIRE-CONTRACT GATE FAILED: 40 emitted field(s) cannot be received.
A tag whose literal string occurs nowhere in the receiving repo cannot be decoded
by any struct, named or anonymous — encoding/json discards it on arrival.
Fix: model the field on the receiving side and say what consults it — or, if it is
deliberately not consumed, add it to ALLOWLIST WITH A REASON. Never a quiet skip.

Blind spots (a green is not full coverage — see the module docstring):
  generic tag names are not checked; reachability of a NAME is not use of a VALUE;
  only the declared ROOTS are covered (hub desired-state and the agent local API
  are NOT).
exit=1
```

## Self-test (a planted unreachable tag on a real root)
```
  planted an unreachable tag on agent HostReport -> gate exit 1, planted tag convicted: True
  unplanted tree -> gate exit 1
SELFTEST OK — the gate convicts a planted unreachable tag and the plant is the only difference.
exit=0
