b87702949 (arm the Policy Gate) and b87703542 (rewrite loop) — it pre-empts neither. Nothing was armed in any deployed environment.The enriched gate catches both real-person incidents production missed at incident time — deterministically (5/5 stability runs each) — and it catches them semantically, where production’s post-incident fix (#6278) catches only the mechanical-token subset. It also correctly passes the RCA 08-15 incident turns that the reverted booking guard wrongly rewrote. That is the claim Fede asked to have proven, and it held.
The caveats are real and measured: (1) latency — the enriched judge answers in ~2.5–5.5s, over the live 2500 ms inline budget on most calls, so it is an async/hold-queue judge today, not an inline one; (2) precision — on a 30-day clean-control replay it would hold 16 of 91 real-person non-voice turns (17.6% raw; 5.5% unexplained-FP after per-row labeling), and while a large share of those holds point at a genuine, systematic content-withholding pattern (the escalation template superseding substantive drafts — exactly the §3.2 omission-residual class), a hold queue at that volume is not armable as-is; (3) scope — it does not subsume the domain guards (the disarmed fee-fabrication guard still owns invented-figure detection; deterministic guards remain the right tool for what they already catch). Recommended posture: arm as measurement/review-queue first (the gate’s own hold path), never inline enforce, and calibrate the completeness check on the labeled classes below.
The claim under test (10k-ft doc §3.3): the existing Policy Gate (evaluatePolicyGate, src/lib/domain/compliance/policy-gate.ts) with its judge enriched with the two missing inputs — the current inbound message and Clara’s reasoning ([[WHY]] proxy) — plus a completeness check (“did the reply answer what was asked / did the draft carry facts the final dropped”), catches the real problematic conversations production’s guards missed, without unacceptable false positives on clean traffic.
fede/guard-poc-enriched-judge): three optional inputs on PolicyGateEvalInput/TrajectoryJudgeInput (inboundMessage, reasoning, undeliveredDraft); flat REQUIRED completeness fields on the judge tool output; an ask-prefilter (detectAskSignals, EN+ES) so the judge also runs on ask-bearing inbounds even when the draft makes no claim (Daniel’s delivered text is claim-free — the claim-only trigger was structurally blind to the omission class). Completeness findings compose to hold (judge.incomplete_reply / judge.dropped_draft_facts) — never block. Reuses the existing gate + registry; no new framework. Unenriched callers are byte-identical to the merged gate (pinned by tests: 16 new, incl. a FAIL-BEFORE pair on the exact Daniel shape).scripts/eval/replay-head-to-head.ts): both pipelines over the same corpus — production = actually-fired safety_check steps + the deterministic GUARD_REGISTRY predicates from replay-guards.ts (the same pure functions the loop imports, per the RCA merge-gate rule); PoC = the enriched gate in shadow, plus the unenriched gate so the delta attributable to enrichment is visible. Read-only prod DynamoDB; judge on the subscription bearer; resume-safe.scripts/eval/willows-shadow-leg.ts): real end-to-end turns on the bench (appfolio-45, org_sandbox, isTest, reserved-range persona) with the gate evaluated in shadow after each settled turn. POLICY_GATE_MODE untouched everywhere.trace_de3ff842…, conv a05c3c99…) — the omission classWhat production did at incident time: every guard passed; the correct draft (application link, prices, special) was discarded by the reply-assembly seam and the delivered reply was the content-free “All set — just let me know your preferred day and time…”. What production does today: the #6278 deterministic salvage catches it — via mechanical tokens (the URL and $ amounts).
What the enriched gate decides (5/5 runs): hold · judge.incomplete_reply — inbound_answered=false (“send me an application for this property” unaddressed) and 5 dropped draft facts named, including the application link, both price ranges, and the one-month-free special. Judge latency ~3.5s.
Why the unenriched gate cannot see it: the delivered text makes no checkable claim, so the claim prefilter never invokes the judge — and even when invoked, a claim-verifier grades what IS in the draft, not what isn’t. Omission is invisible without the inbound. This is the doc’s §3.3 diagnosis, now demonstrated on the real trace.
94cb9d15…) — the false-claim classDelivered reply: “The application link has been sent to you at …” — over an undelivered draft carrying the full fee schedule ($38/$300/$400/$250/$100/$35). No link had been sent. Production at incident time: nothing fired. Production today: #6278 salvage (mechanical tokens).
What the enriched gate decides (5/5 runs): hold · judge.incomplete_reply with 6 dropped draft facts (the fee schedule), and on most runs additionally an unsupported action_done claim on “has been sent”. Judge latency ~5.1s. Note: the claim prefilter alone misses the passive phrasing (“has been sent” matches no first-person action pattern) — the ask-prefilter trigger is what gets the judge invoked here, i.e. the enrichment also widens the judge’s reach on the false-claim class.
Corpus: scripts/eval/corpora/guard-poc-problematic.json — the two real-person incidents, all 7 would-alter rows from #6278’s 30-day replay (labeled in its PR body), and the RCA 2026-08-15 booking-guard real fires (production false positives — a correct layer must PASS those). “Prod registry” = today’s deterministic guard predicates replayed on the turn; “Prod fired” = what actually fired in production history. Every turn of every matched conversation was graded (24 turns).
| Entry | Class | Who | Expected | Prod fired (history) | Prod registry would-alter | PoC enriched | PoC unenriched | Outcome |

| rca-0815-alexis | booking-guard FP | real person | clean | yes | no_fabricated_confirmations (reverted) + escalated_thread_gate | pass | altered | PoC correctly passes (unenriched gate would NOT have — the enrichment removed this FP) |
| rca-0815-ciara | booking-guard FP | real person | clean | yes | reverted guard + escalated_thread_gate | hold (see label) | altered | PoC FP on an incident turn — labeled below |

Reading it: production today catches all 7 draft-drop rows via the #6278 salvage — expected, that guard is merged; the PoC’s value is that it catches the same class semantically (it names the dropped answer even when the drop has no salvageable URL/$ token — dates, policy answers, yes/no commitments) and that it adds the completeness dimension no deterministic guard covers. On the RCA clean rows the enriched gate passes the incident turns the old booking guard wrongly rewrote — with one honestly-reported exception, individually labeled: on two of the three RCA conversations the PoC holds an incident turn. Both of those holds are on the reverted booking guard's own substituted template text (“I've passed this to the property team and they'll confirm a time with you” — sent with no forward on record, because the OLD guard replaced Clara's real reply with that line). The gate's objection to that text is factually true of the text; the pre-rewrite drafts are not recoverable on these traces, so the rows are counted as PoC false positives against the corpus label anyway. Also worth naming: the UNenriched gate would have flagged the Alexis incident turn too — the enrichment (fuller context) is what removed that false positive.
Window: ≥30 days of real production turns (2026-07-27 → today), harness/bench senders excluded, corpus conversations excluded. 686 turns evaluated through BOTH pipelines. The control set is unlabeled real traffic — a PoC hold here is not automatically a false positive; each class below was adjudicated by reading the rows (RCA merge-gate standard applied per class, with per-row detail in the gitignored full report).
| Class | Count | Adjudication |
|---|---|---|
| Voice post-call summaries | 109 | Measurement artifact, excluded from every headline number: voice traces persist a call summary, not an outbound reply, and the live gate never runs on voice at all. A completeness check on a summary is meaningless. (This also says: do not point the enriched judge at voice traces without a voice-specific reconstruction.) |
| Internal / harness / bench senders | 59 | Not real people: team phone numbers from the seed fixtures, propflowai.co addresses, e2e-harness personas, and The Willows bench property's QA traffic — senders the replay's harness filter under-excludes (a filter gap worth fixing in isHarnessTraffic, logged as follow-up). |
| Escalation-template supersession (real people) | 8 | Turns where production's same-turn escalation template replaced a substantive draft with “I've passed this to our team” — and the gate flags the withheld content (deposit explanations, promotion mechanics, approval acknowledgments). Production ALSO alters these turns (it's the template doing the altering), so these are not PoC-only noise: they are the §3.2 omission-residual class occurring in real traffic, measured for the first time. Whether the template SHOULD withhold that content is exactly Fede's open rewrite-loop decision (b87703542) — this is its data. |
| PoC-only holds on live customers | 8 | Individually labeled below: 3 true-positive-leaning, 5 false positives (all low-severity). |
| Turn | What the gate objected to | Label |
|---|---|---|
trace_c0cd5d96… email, prospect (co-signer question) | Pre-tool draft carried the co-signer answer (“handled as part of the application process”); delivered reply deferred it to the team. | TRUE-POSITIVE (lite) — a real answer was withheld at the seam; the Daniel class at low severity. |
trace_48e8b8a8… email, prospect (dumpster question) | “I'll get that confirmed for you from the team” — no forward tool ran; phrasing missed by prod's promise-backing detector. | TRUE-POSITIVE (lite) — the unbacked-handoff-promise class prod's regex detector already targets, caught on a phrasing it misses. |
trace_d07ffa1e… sms, applicant | “The leasing team will review your application and be in touch” — no record. Verdict is repair: fire the forward to make it true; text ships unchanged. | TRUE-POSITIVE (repair) — the gate's designed remedy, zero customer-visible change. |
trace_08175130… + trace_c35a389d… email, resident renewal thread (2 turns) | “Dropped facts” = a personalized greeting, an urgency framing (“only 3 days away”), “I can't adjust rent myself”. | FALSE POSITIVE ×2 — pleasantries/framing counted as substance. Calibration: restrict dropped-fact classes to answers/figures/links/dates. |
trace_4795ca5b… sms, prospect (“See you then”) | “See you tomorrow at 1:00 PM” judged unsupported — but the immediately-prior context reminder says the tour is “tomorrow, Tuesday Aug 18 at 1:00 PM”. | FALSE POSITIVE — date-anchoring artifact. |
trace_39889ccd… email, new lead (tour confirm) | Dropped fact = “1 PM on Saturday is open” — subsumed by the confirmation itself. | FALSE POSITIVE — filler-drop. |
trace_0a708691… sms, resident (paper lease copy) | Dropped the explanation that digital signing goes through the portal; delivered reply still answered the ask. | FALSE POSITIVE (marginal) — explanation nuance, not substance. |
Bottom line on precision: unexplained real-person false positives = 5 of 91 live-customer turns (5.5%), all low-severity, each with a named calibration fix; plus one systematic class (the escalation-template supersession, 8 turns) that is a product decision, not judge noise. The raw 26.8% collapses to that once the voice artifact and harness-sender contamination — both measurement-infrastructure issues, not gate issues — are removed. The unenriched gate on the same 91 turns: 6 would-alter; today's deterministic registry: 32.
What this means: the enriched judge as measured does not fit the production gate's inline 2500 ms budget — at that budget the first corpus pass timed out on 14/20 calls and reported blanket passes (an instrument failure worth remembering: a timed-out judge reads exactly like a clean one). Honest framing for the arm decision: enrichment buys the omission class at the price of an async posture — a post-send shadow scorer / review queue, or a hold-then-send flow on the narrow ask-bearing subset — OR a latency workstream (smaller prompt, faster tier, streaming) before inline enforce is realistic. Numbers here are Haiku (FAST_MODEL) on the subscription bearer; a metered/prod credential path may differ and was deliberately not used.
