oobDegraded tested five things and the sixth never arrived. The agent has emitted `operator_key_configured` on every heartbeat since v0.72.0 — the SAME version that introduced the `oob` stanza carrying it — and store.HostOOBRow mirrored five of the agent's eight OOB fields. With no field for it, encoding/json discarded the fact on arrival, so a box with felhom-sshd active, reachable, a valid config and a configured peer reported `ok` with NO OPERATOR KEY INSTALLED AT ALL. Not a wrong answer: an answer to a question nobody was asking. `operator_peer_configured`, which the hub did read, only says the peer IP is in desired-state — that OOB is MEANT to work, not that entry is possible. Now decoded: operator_key_configured, plus wg_handshake_age_s and healed_at. The last two ride the ALERT TEXT and are deliberately NOT in the predicate — widening a check beyond the fact that is now arriving is how a check stops being read. SCENARIO F, decided on a measurement rather than a preference. operator_key_configured decodes as a POINTER: nil = the agent never said, reported distinctly and never as ok. The version gate was rejected because the field and its stanza shipped in the SAME agent version (v0.72.0), so a stanza without the field cannot come from any released agent; the fleet is 0.113.0/0.127.0 and the vouched floor is 0.127.0. Handled explicitly anyway and pinned, because "cannot happen" is a claim this project has been burned by. THE MESSAGE NAMES THE FAULT. oobDegradedReason is the single source for both predicate and text, so the alert can never name a different fault from the one that fired. The old form derived it separately and had a vocabulary of two — unreachable, or config invalid — with no way to say the key is missing. The operator reads this at 07:00. TESTS DRIVE THE DECODE BOUNDARY. Every hub OOB test before this built a HostOOBRow by hand, and a test written that way CANNOT SEE A FIELD THAT NEVER DECODES — which is how this held a green suite for five weeks. The pre-existing fixture oobReport() also omitted the field, so those scenarios ran against a report shape no released agent produces (same family as R-262). Both fixed. Red-proofs, 8 expected outcomes and 0 wrong, each with the mutation asserted applied: dropping the field returns the false ok; an unconditional check alerts a healthy box; unknown-as-ok restores the silent pass. G-1 CLOSED — scripts/wire_contract_gate.py shipped as ranked, built BEFORE the fixes and seen failing on 40 fields (documentation/tests/wire-contract-gate-2026-08-08/BEFORE.md). Two instrument defects the control caught first: a substring false negative (grep -F healed_at matched privsep_healed_at) and treating dr_recipe as wholly opaque when its top-level sections ARE decoded through an allow-list that already cost offsite_restic (R-122). The prompt for this session said "465 emitted tags, eight unreachable". Checked against the repo: R-260 said "at least eight DECISION-BEARING facts", never eight tags. The real count is 40. R-260 CLOSED (class gated, sharpest instance fixed). R-247 CLOSED (controller v0.209.0). R-264 MINTED and OPEN — the 21 facts with no consumer, allowlisted with reasons so that gating the class could not be mistaken for deciding them. Still open and named: R-246, R-255..R-259, R-261..R-263, and C7's test-comment half. Capability map checked: it claims OOB access is implemented, never monitored, so no row was untrue; what was untrue sat one layer down and the row now records it. repo_gates --fast: all 8 OK. go build/vet/test green in hub, run separately from this commit.
